Pull head pushing structure of double-pull-piece cutting and penetrating machine

Abstract

When the puller pushing structure of the double-pulling-piece cutting and penetrating machine works, the pushing mechanism pushes double-pulling-piece pullers to the position between two puller ejecting pieces one by one, then an air cylinder is started to move downwards, the air cylinder pushes a puller ejecting base to move downwards, and the puller ejecting base is pushed to move downwards. When the double-pull-piece puller is pushed to the next station, the two oppositely-distributed top puller pieces are driven to jointly push the double-pull-piece puller downwards to the next station, meanwhile, the second double-pull-piece puller moves downwards along with the previous double-pull-piece puller, and then the air cylinder returns to drive the top puller base to move upwards, so that the two oppositely-distributed top puller pieces are driven to jointly move upwards, and the double-pull-piece puller is pushed downwards to the next station. At the moment, when moving upwards, the two top pull head pieces rotate by taking the pin as a shaft under the action of the double-pull-piece pull head, the rotation directions of the two top pull head pieces are opposite, namely, the top pull head piece located on the left side rotates clockwise, and the top pull head piece located on the right side rotates anticlockwise, so that a second double-pull-piece pull head is avoided; and after reaching the upper part of the second double-pull-piece pull head, the next material pushing is waited.

Description

Technical Field

[0001] This utility model belongs to the technical field of double-pull-plate cutting and threading machine, and particularly relates to a pull-head pushing structure for a double-pull-plate cutting and threading machine. Background Technology

[0002] The double-tack cutting and threading machine is an automated device that installs double-tack zipper heads onto zippers. The double-tack cutting and threading machines commonly used are designed for double-tack zipper heads. When the double-tack zipper head enters the zipper head die, the zipper tabs will not interfere with the end of the zipper head.

[0003] The existing double-pull-plate cutting and threading machine uses a pusher to push the back of the pull head, which is not suitable for pull heads with pull plates on both sides; the existing double-pull-plate cutting and threading machine cannot achieve the pull head yielding function during the pushing process; therefore, this utility model proposes a pull head pushing structure for a double-pull-plate cutting and threading machine to solve the above problems. Utility Model Content

[0004] This invention provides a pull head pushing structure for a double-pulling-plate cutting and threading machine, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a pull head pushing structure for a double-pull-plate cutting and threading machine, including a top pull head seat;

[0006] The top pull head seat is driven by a cylinder;

[0007] The top pull head seat is provided with a spring seat on its side, and two oppositely distributed top pull head plates are provided on the front side of the top pull head seat, with a double pull tab pull head provided between the two top pull head plates.

[0008] Preferably, there are two spring seats, which are distributed opposite to each other on both sides of the top pull head seat.

[0009] Preferably, the top pull head is rotatably connected to the top pull head seat via a pin.

[0010] Preferably, the double pull tabs are pushed one by one by the pull tab pushing mechanism to the position between the two top pull tabs.

[0011] Preferably, the top pull head seat is driven downward by the cylinder, thereby causing the two top pull head plates to jointly push one of the double pull tab pull heads downward, while the second double pull tab pull head follows and moves downward.

[0012] Preferably, the top pull head seat is driven upward by the cylinder, at which time the two top pull head plates rotate around the pin as an axis.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] During operation, the pushing mechanism pushes the double-pull tab pull heads one by one to the position between the two top pull head tabs. Then, the cylinder is activated to move downward, pushing the top pull head seat downward. This causes the two relatively distributed top pull head tabs to jointly push the double-pull tab pull head (the first double-pull tab pull head) downward to the next station. At the same time, the second double-pull tab pull head will follow the first double-pull tab pull head downward. Then, the cylinder returns to its original position, causing the top pull head seat to move upward. This causes the two relatively distributed top pull head tabs to move upward together. At this time, when the two top pull head tabs move upward, they will rotate around the pin as an axis under the action of the double-pull tab pull head. The two top pull head tabs rotate in opposite directions, that is, the top pull head tab on the left rotates clockwise, and the top pull head tab on the right rotates counterclockwise. This avoids the second double-pull tab pull head and reaches above the second double-pull tab pull head, waiting for the next push. This utility model is suitable for pull heads with pull tabs on both sides and solves the problem of the pull head's clearance function. Attached Figure Description

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0022] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figures 1 to 3 This utility model provides a technical solution: a pull head pushing structure for a double pull head cutting and threading machine, including a top pull head seat 1; the top pull head seat 1 is driven by a cylinder; a spring seat 2 is provided on the side of the top pull head seat 1, and two oppositely distributed top pull head plates 3 are provided on the front side of the top pull head seat 1, with a double pull head 5 provided between the two top pull head plates 3.

[0026] For further details, please refer to Figure 1 There are two spring seats 2, which are distributed opposite each other on both sides of the top pull head seat 1.

[0027] For further details, please refer to Figure 1 The top pull head plate 3 is rotatably connected to the top pull head seat 1 via pin 4.

[0028] In this embodiment, the double pull tab 5 is pushed one by one by the pull tab pushing mechanism to the position between the two top pull tabs 3 (the pull tab pushing mechanism is the prior art, and its function is also commonly used by those skilled in the art, so it will not be described in detail). The two top pull tabs 3 will not rotate when they move downwards, but will rotate under the action of the double pull tab 5 when they move upwards. The two top pull tabs 3 rotate in opposite directions, that is, the top pull tab 3 on the left rotates clockwise, and the top pull tab 3 on the right rotates counterclockwise.

[0029] During operation, the pushing mechanism pushes the double-pulling heads 5 one by one to the position between the two top-pulling heads 3. Then, the cylinder is activated to move downward, pushing the top-pulling head seat 1 downward. This causes the two relatively distributed top-pulling heads 3 to jointly push the double-pulling heads 5 (the first double-pulling head 5) downward to the next station. At the same time, the second double-pulling head 5 will follow the first double-pulling head 5 downward. Then, the cylinder returns to its original position, causing the top-pulling head seat 1 to move upward. This causes the two relatively distributed top-pulling heads 3 to move upward together. At this time, when the two top-pulling heads 3 move upward, they will rotate around the pin 4 under the action of the double-pulling heads 5. The two top-pulling heads 3 rotate in opposite directions, that is, the top-pulling head 3 on the left rotates clockwise, and the top-pulling head 3 on the right rotates counterclockwise. This avoids the second double-pulling head 5 and reaches above the second double-pulling head 5, waiting for the next push.

[0030] The working principle and usage process of this utility model are as follows: During operation, the pushing mechanism pushes the double pull tabs 5 one by one to the position between the two top pull tabs 3. Then, the cylinder is activated to move downward, and the cylinder pushes the top pull tab seat 1 downward, thereby driving the two relatively distributed top pull tabs 3 to jointly push the double pull tabs 5 (the first double pull tab 5) downward to the next station. At the same time, the second double pull tab 5 will follow the first double pull tab 5 downward. Then, the cylinder returns to its original position and drives the top pull tab seat 1 upward, thereby driving the two relatively distributed top pull tabs 3 to move upward together. At this time, when the two top pull tabs 3 move upward, they will rotate around the pin 4 as an axis under the action of the double pull tabs 5. The two top pull tabs 3 rotate in opposite directions, that is, the top pull tab 3 on the left rotates clockwise and the top pull tab 3 on the right rotates counterclockwise, thereby avoiding the second double pull tab 5 and reaching above the second double pull tab 5, waiting for the next push.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
