Description

Automatic pulp molding equipment

The invention relates to the technical field of automatic pulp molding equipment, especially an automatic pulp molding equipment that can realize synchronous processing in the reciprocating strokes of several stations.

At present, known automatic pulp molding machines, such as Chinese invention patent CN1426363A and US invention patent US6,352,617, disclose a combination of multiple processing stations, such as including a suction molding station and a disposable heating Each station is equipped with a pair of upper and lower corresponding molds and a reciprocating moving device. The reciprocating moving device is used to perform a one-way processing stroke on each paper product, but its reverse direction The return trip is not subject to any processing. The definition of the so-called "one-time hot pressing and shaping station" here refers to: when the suction mold of the suction molding station vacuums a pulp tank (Slurry Tank) to form a pulp made of high-humidity plant fibers After the rough billet (the moisture content accounts for more than 60% of the overall weight of the rough billet), then the rough billet is only pressed against the rough billet through the two upper and lower hot pressing molds in the one-time hot pressing and shaping station." "One-time hot-pressing process" mold clamping, that is, using the one-time hot-pressing process to remove most of the moisture contained in the high-humidity plant fiber in the rough, or even immediately realize a one-time drying of the paper product; However, the one-time hot-pressing process through the one-time hot-press shaping station To remove most of the moisture contained in the rough blank at one time, the time course of the one-time hot pressing process required by it will take about 160 seconds (or more) to obtain each completely dried paper product. Undoubtedly prolonging the working cycle (Cycle Time) of each paper product, and correspondingly prolonging the total processing time of each batch of paper product output; at the same time, it is desirable to once within 160 seconds of the one-time hot pressing process. To remove most of the moisture contained in the rough blank means that within the process time of 160 seconds, the mold clamping pair of the two upper and lower hot pressing molds of the one-time hot pressing and shaping station must be The mold clamping pressure and the one-time heating temperature of the one-time hot pressing process are carried out on the rough blank, which not only easily causes the paper product to be poorly dried (such as not completely dried), but also needs to be greatly increased in an instant. Both the clamping pressure and the one-time heating temperature of the one-time hot-pressing process; however, both of them need to be greatly increased instantaneously; however, such high temperature and high pressure processing conditions are very likely to cause the structure of the paper product to break, It makes the molding surface rough, has many burrs, and increases the defective rate of the product, especially for the paper product that needs hot pressing to extrude a kind of paper product with a longitudinal depth of the transverse molding surface that is greater than 1 cm.

For example, in a time sequence diagram of a processing cycle of the conventional automatic pulp molding machine with a unidirectional processing stroke as shown in FIG. The station is used as the initial point O of the processing cycle T of each paper product. In the reciprocating mobile device, a transfer mold for absorbing paper products is driven from the suction along the single processing direction S1 (that is, the sequential processing direction) The pulp forming station moves to the one-time thermoforming station, which is called "one-way processing stroke". Assume that the corresponding production processes of the slurry suction forming station and the one-time thermoforming station in the direction of the one-way processing direction S1 are respectively t1 and t2 (where t2 also includes the reciprocating moving device The moving time of the transfer mold of the mobile adsorption paper product to the disposable hot-pressing shaping station, and the up-and-down moving time of the upper and lower hot-pressing molds, so t2 is a one-time hot-pressing process time course greater than 160 seconds); in this reciprocating A mobile device transports the paper product to the disposable thermoforming station After placing, then the reciprocating mobile device must take the transfer mold and spend a return time t3 along a return direction S2 that is opposite to the processing direction S1 to return to the slurry suction forming station for homing. Even if the last working cycle T of the paper product is finished, the next working cycle T of the paper product can be restarted from the initial point 0 at the same time, so the return time t3 of the reciprocating moving device is approximately equal to the pulp suction The sum (t3=t1+t2) of the corresponding production process time schedules t1 and t2 of the forming station and the one-time hot-pressing and shaping station, so that the conventional automatic pulp molding with one-way processing stroke The entire processing cycle of the forming machine for each paper product is T=t1+t2+t3; in other words, once the corresponding production process schedule of each station in the conventional automated pulp molding machine (also Including the respective corresponding return time of the reciprocating mobile device) is lengthened, it will naturally lengthen the time length of the working cycle T of each of the paper products; at the same time, when the reciprocating mobile device carries The transfer mold moves along the return direction S2 from the one-time hot press shaping station back to the return time t3 of the pulp suction molding station for homing, the conventional automatic pulp molding machine In essence, each station does not perform any processing on each paper product, resulting in poor mass production efficiency. In addition, since the pulp suction molding station of the conventional automatic pulp molding machine is also provided with a turning mechanism for turning the lower molding surface of the lower pulp suction mold 180 degrees, the turning mechanism is mostly driven by hydraulic pressure /Hydraulic cylinder, servo motor, push rod, steering gear and other structures not only make the structure too complicated, but also lead to high equipment cost and high maintenance cost. The lower molding surface of the lower molding surface is alternately flipped by 180 degrees to carry out several production processes of downward suction or upward mold clamping, but the time required for the bottom suction mold to be turned over further lengthens each The time length of the duty cycle T of the paper product.

Although, another kind of conventional automatic pulp molding machine has appeared at present, can Able to carry out reciprocating and alternating processing strokes, which includes a slurry suction molding station located in the middle of the machine (also equipped with a turning mechanism that turns the lower molding surface of the lower slurry suction mold for 180 degrees alternately), left and right two groups Disposable hot-pressing and shaping stations of the same size (that is, each group of the one-time hot-pressing and shaping station includes two hot-pressing molds with corresponding upper and lower molds) are respectively connected side by side to the suction molding station left and right sides, and at least one reciprocating mobile device. In a time sequence diagram of a processing cycle of the conventional automatic pulp molding machine with reciprocating and alternate processing strokes as shown in Figure 2, every two suction molding processes performed by the pulp suction molding station in sequence The time courses are t1 and t1' respectively, and there is a period of time K1 between the time courses t1 and t1' of each two slurry suction forming processes. After that, the at least one reciprocating moving device moves along the The left and right two alternate processing directions S1 and S1', which are opposite to each other, reciprocate and alternately drive the designated hot-pressing upper die (or hot-pressing lower die) of the left and right two sets of disposable hot-pressing shaping stations to move to the suction forming station. station (the initial point of the time sequence is O) to absorb the corresponding rough blanks produced by it and alternately transfer the corresponding rough blanks to the left and right two groups of disposable hot-pressing and shaping stations, so as to carry out every two hot-pressing and shaping processes respectively The time schedule t2, t2' is the so-called "reciprocating alternate processing stroke"; however, there will be a waiting period between the time schedule t2 of the first hot-pressing shaping process and the time schedule t1 of the second slurry suction molding process ( Idle) and no action time difference G1, the waiting idle time difference G1 represents: when the designated hot-pressing upper mold of one group of one-time hot-pressing and shaping workstations is preparing to move to the suction molding station to absorb the corresponding rough blank, another group of one-time hot-pressing and shaping stations are waiting for idle (Idle) without any action; secondly, during the two-stage hot-pressing process shaping time course t2, t2', the at least one The reciprocating moving device sequentially reciprocates and alternately drives the designated hot-pressing upper dies of the left and right groups of disposable hot-pressing and shaping stations to absorb the corresponding rough blank along the two sides respectively opposite to the two alternate processing directions S1, S1'. The return direction S2, S2' returns to the two groups of one-time hot-pressing and shaping stations to perform one-time hot-pressing process on each of the two corresponding rough blanks, so the conventional automated paper with reciprocating and alternate processing strokes The pulp molding machine is used to reciprocate and alternately produce every two corresponding paper products. Every two processing cycles T1 and T2 are T1=t1+t2 and T2=t1'+t2' respectively. The corresponding designated hot-pressing mold of the permanent hot-pressing shaping station still carries out the "one-time hot-pressing process schedule" of about 160 seconds for each corresponding rough billet, but another group of one-time hot-pressing shaping However, the workstation may be waiting for idle (Idle) without action (so there is a time difference G1 of several production processes waiting to be idle), so it still cannot effectively solve the above technical problems: the time schedule of several production processes for each batch The structure of paper products that are elongated and mass-produced is easy to break, their molding surface is rough and has many burrs, and the defective rate of products increases.

In order to solve the above-mentioned technical problems and shortcomings of various conventional automatic pulp molding equipment, it is necessary to propose an improved automatic pulp molding equipment and an automatic pulp molding method.
