[0010] Furthermore, the clamping mechanism includes a connecting spring, and the connecting spring is fixedly connected to the bottom end of the connecting block, the bottom end of the connecting spring is fixedly connected to the sliding block, and the sliding block is rotatably connected to a connecting rod, one side of the connecting rod is connected to the adjusting roller, and sliding grooves are provided at the upper ends of both sides of the outside of the mounting frame, and one side of the connecting rod passes through and extends to the inner side of the mounting frame.

[0011] Furthermore, a damper is arranged inside the connecting spring, and the top end of the damper is connected to the connecting block, and the bottom end of the damper is connected to the sliding block.

[0012] Furthermore, in order to operate, the transmission mechanism includes a rotating block, and one side of the rotating block is connected to the driving gear, the outer side of the rotating block is fixedly connected to an eccentric wheel, and a limit frame is provided on the other side of the mounting plate outside the eccentric wheel, a connecting frame is fixedly connected to the middle position of the top of the limit frame, and one side of the connecting frame is connected to the connecting rod.

The anti-skid mechanism includes an anti-skid plate, and the anti-skid plate is fixedly connected to the other side of one end of the top of the fixed base plate. A plurality of anti-skid protrusions are fixedly connected to the top of the anti-skid plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Align the positions of the cloth belt and the chain teeth and place them at one end between the adjusting roller and the fixed roller. The output end of the driving motor can drive the driving gear to rotate, so that the driving gear can drive the driven gear to rotate. During the rotation process, the rotation directions of the driven gear and the driving gear are different, so that the material is pushed between the adjusting roller and the fixed roller to realize automatic feeding, avoiding the need to manually drive the cloth belt and the chain teeth forward and feed the material, thereby increasing the overall working efficiency of the device;

[0017] Furthermore, when in use, by placing the cloth tape and the chain teeth that need to be arranged on the anti-slip plate and the anti-slip protrusion, and by utilizing the anti-slip performance of the anti-slip plate and the anti-slip protrusion, the cloth tape and the chain teeth can be more stably aligned and spliced, thereby increasing the applicability during use;

[0018] Furthermore, the adjusting roller and the fixed roller can also smoothly rotate relative to each other and feed the cloth belt and the chain teeth, and the driving gear can stably control the speed of the driven gear, so that the whole is more stable when conveying materials;

[0019] 2. The adjusting roller and the fixed roller can also play a clamping role, so as to reinforce the position of the chain teeth and the cloth belt. In the process of automatic feeding, the position of the fixed roller is fixed and can only rotate. During the rotation of the adjusting roller, the connecting spring is used to make the adjusting roller press downward by its own weight, so as to squeeze the chain teeth and the cloth belt to avoid position deviation. At the same time, the damper can be used to prevent the connecting spring from shaking due to the elastic force, causing the adjusting roller to move up and down continuously. The sliding groove can facilitate the connection rod to pass through and connect with the adjusting roller, so as to adjust the height of the adjusting roller and increase the overall flexibility in use.

[0020] Furthermore, during the feeding process, it is necessary to ensure that the adjusting roller moves up and down and clamps the material. The active gear can drive the rotating block to rotate when it rotates, and the eccentric wheel on the outside of the rotating block is driven and rotated, so that the eccentric wheel rotates within the range of the limit frame. When one side of the eccentric wheel rotates 90° or 270°, the limit frame will be pushed upward or downward, so that the connecting frame drives the connecting rod to rotate. At the same time, due to the auxiliary connection of the limit frame, the position of the adjusting roller can also be changed in height, thereby facilitating better use of the device.

[0032] The upper ends of both sides of the outside of the mounting frame 4 are fixedly connected with connecting blocks 11, and the bottom ends of the connecting blocks 11 are provided with clamping mechanisms, which can clamp the materials to facilitate the conveying of the automatic feeding mechanism and prevent positional deviation during the conveying process.

[0033] The automatic feeding mechanism includes a mounting plate 7, and the mounting plate 7 is fixedly connected to one side of the top of the fixed base plate 1, the lower end of one side of the mounting plate 7 is rotatably connected to a driving gear 10, one side of the driving gear 10 is fixedly connected to a driving motor 8 through a coupling, and the output end of the driving motor 8 is connected to the driving gear 10, and one side of the mounting plate 7 above the driving gear 10 is rotatably connected to a driven gear 9, and the driven gear 9 and the driving gear 10 are meshed with each other.

[0034] An anti-skid mechanism is fixedly connected to the other side of the top end of the fixed base plate 1. The anti-skid mechanism is used for staff to organize cloth belts and chain teeth to facilitate subsequent material feeding.

A plurality of anti-skid protrusions 22 are fixedly connected to the top of the anti-skid plate 21.

[0035] In this example, the positions of the cloth belt and the chain teeth are aligned and then placed at one end between the adjusting roller 5 and the fixed roller 6. The output end of the driving motor 8 can drive the active gear 10 to rotate, so that the active gear 10 can drive the driven gear 9 to rotate. During the rotation process, the driven gear 9 and the active gear 10 have different rotation directions, so that the material is pushed between the adjusting roller 5 and the fixed roller 6, realizing automatic feeding, avoiding the need to manually drive the cloth belt and the chain teeth forward and feed the material, and increasing the overall work efficiency of the device during operation.

[0036] Embodiment 2:

[0037] like Figure 1 , Figure 2 and Figure 3The technical solution shown is based on Example 1, in order to solve the problem that it is inconvenient to maintain the connection distance between the cloth tape and the chain teeth during the feeding process: the feedable zipper sewing machine discloses a clamping mechanism, the clamping mechanism includes a connecting spring 12, and the connecting spring 12 is fixedly connected to the bottom end of the connecting block 11, the bottom end of the connecting spring 12 is fixedly connected to a sliding block 14, and the sliding block 14 is rotatably connected to a connecting rod 15, one side of the connecting rod 15 is connected to the adjusting roller 5, and sliding grooves 16 are provided at the upper ends of both sides of the outside of the mounting frame 4, and one side of the connecting rod 15 passes through and extends to the inner side of the mounting frame 4.

The sliding groove 16 can facilitate the connecting rod 15 to pass through and connect with the adjusting roller 5, so as to adjust the height of the adjusting roller 5 and increase the overall flexibility during use.

[0040] Embodiment three:

A connecting frame 19 is fixedly connected to the middle position of the top of the limit frame 17, and one side of the connecting frame 19 is connected to the connecting rod 15.

[0042] The limiting frame 17 and the mounting plate 7 are slidably connected, and the sliding block 14 and the mounting frame 4 are slidably connected.

[0043] In this example, during the feeding process, it is necessary to ensure that the adjusting roller 5 moves up and down and clamps the material.
