Abstract
The invention discloses a pull rod type single-point valve needle cylinder, which comprises a cylinder body, a cylinder bottom cover, a connecting rod and a piston arranged between the cylinder body and the cylinder bottom cover; the cylinder body comprises a cylinder block and a boss arranged on the cylinder block; the piston is inserted in the boss of the cylinder body; the cylinder bottom cover is fixed on the cylinder body, and covers the piston; a compressed air chamber is formed between the piston, the cylinder body and the cylinder bottom cover; the cylinder body is provided with a pull rod-fixing hole corresponding to the position of the piston, and a pull rod runs through the pull rod-fixing hole to fixedly connect with the piston. By means of the method, the pull rod type single-point valve needle cylinder can increase the pushing force of the moving piston, a valve needle does not move back, and adhesive opening sealing is table; cylinder cooling is rapid, and the working state is stable.
Description
Technical field
The present invention relates to high pressure cylinder field, particularly relate to a kind of pull-rod type single-point needle cylinder.
Background technique
When sealing, by the thrust of cylinder piston, needle is fixed, because sealing pressure is large, existing air cylinder structure delivery air chamber is little, and when piston movement, thrust is inadequate, causes needle to retreat, and incessantly glue of Jiao Kou envelope, affects quality of product.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of pull-rod type single-point needle cylinder, the thrust can increase piston movement time, and needle can not retreat, and the sealing of glue mouth is stable; Cylinder is cooling rapidly, stable working state.
For solving the problems of the technologies described above, the present invention adopt a technological scheme be: a kind of pull-rod type single-point needle cylinder is provided, comprises: cylinder block, cylinder bottom, connecting rod and be arranged on cylinder block and cylinder bottom between piston; Described cylinder block comprises cylinder block and is arranged on the boss on cylinder block; Described piston sleeve is on the boss of described cylinder block; Described cylinder bottom is fixed in cylinder block, and cylinder bottom covers described piston; Between described piston and the gentle cylinder bottom head of described cylinder block, form delivery air chamber; In described cylinder block, the position of corresponding piston is provided with pull bar fixed hole, and described pull bar is connected and fixed through pull bar fixed hole and described piston.
Preferably, the boss center of described cylinder block has main body mounting hole; In described cylinder block, be provided with cooling water channel, in described cylinder block, have the water intake and the water outlet that are communicated with described cooling water channel; Described main body mounting hole inwall is provided with stuffing box gland, and described stuffing box gland excircle is provided with water-stop sheet; The inwall of described stuffing box gland and described main body mounting hole forms the cavity of sealing; Described cavity is communicated with water intake and water outlet by described cooling water channel, and cavity and described cooling water channel form two joints; Described water-stop sheet is arranged between two joints of described cooling water channel and cavity, and water-stop sheet cuts off described cavity.
The invention has the beneficial effects as follows: piston thrust of the present invention is large, needle can not retreat, and the sealing of glue mouth is stable.
Brief description of the drawings
Fig. 1 is the sectional structure schematic diagram of a kind of pull-rod type single-point of the present invention needle cylinder one preferred embodiment;
Fig. 2 be shown in a kind of decomposition texture schematic diagram of pull-rod type single-point needle cylinder;
In accompanying drawing, the mark of each parts is as follows: 1, cylinder block; 2, cylinder bottom; 3, piston; 4, stuffing box gland; 5, pull bar fixed hole; 6, cooling water channel; 7, delivery air chamber; 8, cavity.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of pull-rod type single-point needle cylinder, comprising: cylinder block 1, cylinder bottom 2, connecting rod and be arranged on cylinder block 1 and cylinder bottom 2 between piston 3; Described cylinder block 1 comprises cylinder block and is arranged on the boss on cylinder block; Described piston 3 is enclosed within on the boss of described cylinder block; Described cylinder bottom 2 is fixed in cylinder block 1, and cylinder bottom 2 covers described piston 3; Between the gentle cylinder bottom head 2 of described piston 3 and described cylinder block 1, form delivery air chamber 7; In described cylinder block 1, the position of corresponding piston 3 is provided with pull bar fixed hole 5, and described pull bar is connected and fixed through pull bar fixed hole 5 and described piston 3.Pull bar pulls piston 3, and piston 3 is in the interior movement of delivery air chamber 7, and pressurized air, provides thrust to needle.The boss center of described cylinder block 1 has main body mounting hole; In described cylinder block, be provided with cooling water channel 6, in described cylinder block 1, have the water intake and the water outlet that are communicated with described cooling water channel 6; Described main body mounting hole inwall is provided with stuffing box gland 4, and described stuffing box gland 4 excircles are provided with water-stop sheet; Described stuffing box gland 4 forms with the inwall of described main body mounting hole the cavity 8 sealing; Described cavity 8 is communicated with water intake and water outlet by described cooling water channel 6, and cavity 8 forms two joints with described cooling water channel 6; Described water-stop sheet is arranged between two joints of described cooling water channel 6 and cavity 8, and water-stop sheet cuts off described cavity; Cooling water enters cavity 8 by cooling water channel 6 from a joint from water intake, cooling water after heat absorption flows out from water outlet by cooling water channel 6 from another joint, due to the blocking-up of water-stop sheet, the cooling water that flows into cavity 8 can not flow with the hydration of flowing out, good cooling results, provide safeguard to the stable operation of cylinder, the thrust that cylinder offers needle is stable.Thrust when the present invention can provide piston movement, needle can not retreat, and the sealing of glue mouth is stable; Cylinder is cooling rapidly, stable working state.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
