Description

A detachable synchronizer

technical field

The invention relates to the technical field of splicing machines, in particular to a detachable synchronizer.

Background technique

When the ZJ27 tipping machine produces cigarette products of different specifications, it is necessary to complete the equipment modification of different specifications and replace different types of raw and auxiliary materials at the same time. Among them, when the equipment chooses pre-punched tipping paper, there is no glue area on the surface of the tipping paper after being glued by the top roller, so as not to block the pores.

In order to ensure the quality of cigarette rubbing, the glued tipping paper must be synchronized with the tipping paper cutter to ensure that the cutting line is staggered in the glue-free area. The function of the synchronizer: it can make the cutting line staggered to the non-glue area to avoid the glue accumulation of the cutter; it can also pull the glued tipping paper back to a certain distance, so that the tipping paper can be adjusted to the mouth stick and cigarettes in the next process after cutting. bonding.

Since the glue-free area of different tipping papers is different, the synchronizer is also different, which is reflected in the glue-free area of the synchronizer, which means that the synchronizer must be replaced every time the brand is changed, which is time-consuming and laborious. Through the survey, it was found that: ① The frequency of synchronizer replacement is high, with an average of 15 times of synchronizer replacement per month; ② The replacement of synchronizers takes a long time, with an average of 60 minutes for each synchronization replacement; inconvenient.

The synchronization device consists of a synchronizer and two paper guide rollers. The synchronizer is an independent flat solid shaft, which is connected to the pulley drive through a flat key. Two 61901 bearings are installed on the synchronization bracket. The synchronizer rotates counterclockwise through the belt drive. The two paper guide rollers are fixed by their own locking screws, and the two sides are supported by bearings, which can rotate freely.

In the prior art, the steps for replacing the synchronizer are as follows: ① The paper guide roller frame needs to be removed first, that is, the two M4 locking screws are removed, and the paper guide roller frame can be pulled out. ② Loosen the tensioning device of the synchronizer, that is, remove the anti-wire M5 locking screw. ③Remove the synchronizer, that is, loosen the three M3 locking screws, and the synchronizer and other related parts can be pulled out. ④ Remove the screws, washers, pulleys, retaining springs, bearings, spacers and other related components on the synchronizer in sequence. ⑤ Replace the synchronizer with a new one. ⑥Install spacer sleeves, bearings, circlips, pulleys, gaskets, screws and other related components on the synchronizer in sequence. ⑦Install the synchronizer and tighten the three M3 locking screws. ⑧Tension synchronizer tensioning device, that is, install the anti-wire M5 locking screw. ⑨Install the paper guide roller frame in place, that is, tighten the two M4 locking screws. It can be seen that there are many steps to replace the synchronizer, which is time-consuming and labor-intensive.

A detachable synchronizer involved in the embodiment of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the following examples are only used to explain the present application and do not constitute a limitation to the present application.

In order to avoid dismantling the relevant parts of the synchronizer, thereby improving the replacement efficiency of the synchronizer, this application adopts a detachable design for the synchronizer. Combined design of the action part and base part of the synchronizer. When replacing the synchronizer, it can be operated directly on the equipment, and it can be done in one step.

The synchronizer in the prior art is shown in Figure 1-2. Through research on the synchronizer, it is found that the left area is the active part 1 of the synchronizer, the right area is the base part of the synchronizer, and the middle area is the non-active part. 2, that is, not involved in the work of the synchronizer. For this reason, the application intends to improve the intermediate area of the synchronizer—the non-active part 2.

As shown in Figures 3-5, a detachable synchronizer includes: an active part 1, and a base part 3, the appearance of the active part 1 and the base part 3 of the present application are the same as those of the synchronizer in the prior art There is no difference, so I won't repeat it here. Only in the middle of the action part 1 of the present application is a positioning hole 8 axially opened; a first step 6 is provided at one end of the action part 1; The second step 4 matched with the first step 6 is provided with a positioning rod 5 matched with the positioning hole 8 at the end of the second step 4; connecting parts, the active part 1 is connected to the base through the positioning hole 8 The cooperation of the positioning rod 5 of the seat part 3 realizes assembly positioning, so that the first step 6 fits with the second step 4 , and the connecting part is used to lock the fitted first step 6 and the second step 4 .

That is, the inactive part 2 of the synchronizer in the prior art is improved, and a positioning hole 8 is provided in the inside of the active part 1 respectively, and a positioning rod 5 is provided on the end face of the base part 3, whether it is the positioning hole 8 or the positioning The rod 5 does not affect the respective original functions of the acting part and the base part 3, and the connecting end faces of the acting part 1 and the base part 3 are respectively provided with a first step 6 and a second step 4. locking. The locked position of the first step 6 and the second step 4 is located at the inactive part 2 of the synchronizer in the prior art, and the maximum diameters of the first step 6 and the second step 4 are smaller than or equal to the Maximum diameter of active part 1. Does not affect the function of the synchronizer. But it can greatly improve the disassembly effect of the synchronizer.

Preferably, both the first step 6 and the second step 4 are circular, and the diameters of the first step 6 and the second step 4 are both equal to the maximum diameter of the active part 1 . The processing and installation of the first step 6 and the second step 4 are facilitated, and the function of the synchronizer is not affected while realizing the connection between the active part 1 and the base part 3 .

In some embodiments, the connecting parts are bolts 7 and nuts, and two sets of corresponding via holes are respectively opened on the first step 6 and the second step 4, and the nuts will pass through the first step 6 and the second step 4 in turn. The bolt 7 of the through hole on the second step 4 is locked. Two sets of corresponding via holes are opened on both sides of the active part 1 respectively.

The statistical data of the time-consuming replacement of the synchronizer before and after the improvement is shown in the table below. At the same time, the improved synchronizer has been continuously observed. The bonding quality of the tipping paper is good, and there is no negative impact on the product quality.

Through data analysis, it is found that the average time to replace the synchronizer before the improvement is 60.9min/time, and the average time to replace the synchronizer after the improvement is 3.3min/time, which improves the replacement efficiency by 1745.45%, which is quite valuable.
