DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-4 As shown, a clamping mechanism for a zipper head includes a base 1, a mobile mechanism 2 installed on the base 1, a front clamping mechanism 3, and a rear clamping mechanism 4. The front clamping mechanism 3 and the rear clamping mechanism 4 clamp the zipper head from the front and rear ends. After the previous process is completed, the zipper head is sent in and clamped between the front clamping mechanism 3 and the rear clamping mechanism 4. After the next process is completed, the zipper head is sent out for insertion into the zipper. The zipper head is limited by clamping the zipper head to prevent the zipper head from falling due to vibration during the working process. The rear clamping mechanism 4 is installed on the upper end of the mobile mechanism 2, and the mobile mechanism 2 drives the rear clamping mechanism 4 to move so as to clamp or release the zipper head.

[0024] A lifting mechanism 5 is provided between the front clamping mechanism 3 and the rear clamping mechanism 4, and the zipper head is placed on the upper end of the lifting mechanism 5. The height of the zipper head is adjusted by the lifting mechanism 5 to adapt to zipper heads of different thicknesses, which helps to detach the zipper head during the working process and enter the next step. Before the machine starts working, the height of the lifting mechanism 5 is adjusted according to the specifications of the zipper head to be used, and zipper heads of different thicknesses can be compatible to meet the versatility of user use. This device can be used to adapt to zipper heads of different sizes, and users do not need to purchase machines of different sizes according to each zipper head of different sizes, which is convenient for users to use and saves costs.

[0025] The moving mechanism 2 shown includes a slide rail fixed on the base 1 and a slider 8 installed on the upper end of the slide rail 7, and a cylinder 8 installed on one side of the front clamping mechanism 3. The slider 8 can slide on the slide rail 9. The gas rod of the cylinder 8 passes through the front clamping mechanism 3 and is connected to the slider 8. The rear clamping mechanism 4 is installed on the upper end of the slider 8. The slider 8 is driven to move laterally by contraction of the gas rod, and the rear clamping mechanism is driven to move laterally at the same time, thereby clamping or releasing the zipper head.

[0026] A clamping groove 8 is formed between the lifting mechanism 5 and the front clamping mechanism 3 and the rear clamping mechanism, and the clamping groove 8 is adapted to the outer contour of the zipper head, and the scraper of the zipper head faces downward and is clamped in the clamping groove 8. The contour of the clamping groove 8 is adapted to the outer contour of the zipper head, which can further limit the zipper head to prevent it from falling off.

[0027] The lifting mechanism 5 shown includes a front lifting block 6 on the inner side of the front clamping mechanism 3 and a rear lifting block 7 on the inner side of the rear clamping mechanism 4. The front and rear ends of the zipper head are respectively placed on the upper ends of the front lifting block 6 and the rear lifting block 6. The clamping groove 8 is formed between the front lifting block 6 and the side wall of the front clamping mechanism 3, and between the rear lifting block 7 and the side wall of the rear clamping mechanism 4. The up and down displacement of the front lifting block 6 and the rear lifting block 7 can change the height of the clamping groove 8. Before the work starts, the height of the clamping groove 8 is adjusted to be equal to the thickness of the top sheet of the zipper head, which ensures that the zipper head can be stably clamped and helps the manipulator to easily remove the zipper head from the clamping groove 8.

[0028] As shown, a spring block 9 is provided below the front lifting block 6, a spring groove 10 is provided at the bottom of the front lifting block 6, a spring 11 is provided between the spring block 9 and the spring groove 10, and the spring 11 is embedded in the spring groove 10 to prevent the spring 11 from falling off. The spring block 9 is fixed to the front clamping mechanism 3 by a threaded manner, and is used to support the spring 11 at the lower end, and the spring 11 plays a role in assisting the displacement of the front lifting block 6. Similarly, an adjustment block 12 is provided at the center position of the lower end of the rear lifting block 14, and a spring groove 10 is also provided at the bottom of the rear lifting block 14. A spring 11 is provided between the spring groove 10 and the adjustment block 12, and the adjustment block 12 plays a role in supporting the spring 11 at the bottom, and the lower end of the spring 11 is placed on the adjustment block 12, and the upper end is embedded in the spring groove 11, and the spring 11 plays a role in assisting the displacement of the rear lifting block 7.

[0029] The front clamping mechanism 3 and the rear clamping mechanism 4 are both provided with a first through hole 13, and the front lifting block 6 and the rear lifting block 7 are both provided with a first threaded hole 14 corresponding to the position of the first through hole 13. The diameter of the first through hole 13 is larger than the first threaded hole 14. A fixing screw 18 is provided to pass through the first through hole 13 and screw into the first threaded hole 14. The front lifting block 6 and the rear lifting block 7 are respectively fixed to the inner side of the front clamping mechanism 3 and the rear clamping mechanism 4 by the fixing screw 18. When the height of the front lifting block 6 or the rear lifting block 7 needs to be adjusted, the fixing screw 18 needs to be loosened first, and the fixing screw 18 needs to be tightened again after the adjustment is completed to prevent the vibration during the working process from causing the height of the front lifting block 6 or the rear lifting block 7 to change. After the height of the front lifting block 6 and the rear lifting block 7 changes, the positional relationship of the first threaded hole 14 will also change, and the position of the first through hole 13 is constant. Since the diameter of the first through hole 13 is larger than the first threaded hole 14, the fixing screw 18 can still pass through the through hole 13 and be screwed into the first threaded hole 14. The larger size is the distance that the front lifting block 6 or the rear lifting block 7 can be displaced up and down.

[0030] The front clamping mechanism 3 and the rear clamping mechanism 4 are provided with a second threaded hole 16, which is located on one side of the first through hole 13; the front lifting block 6 and the rear lifting block 7 are provided with a second through hole 15, which is located on one side of the first threaded hole 14, and the second through hole 15 corresponds to the second threaded hole 16. The second through hole 20 is provided with a tilting block 17, and an adjusting screw 19 is screwed into the second threaded hole 16 and penetrated into the second through hole 15, and the end of the adjusting screw 19 abuts against the tilting block 17. The adjusting screw 19 is screwed inward, and the adjusting screw 19 moves along the inclined surface of the tilting block 17. The more it is screwed inward, the more the adjusting screw 19 abuts against the high point of the inclined surface. Since the height of the adjusting screw 19 is always constant, the tilting block 17 is squeezed to move downward, driving the front lifting block 6 or the rear lifting block 7 to move downward. The adjusting screw 19 is gradually withdrawn outward, and the front lifting block 6 or the rear lifting block 7 gradually rises due to the rebound force of the lower end spring 11. The heights of the front lifting block 6 and the rear lifting block 7 can be adjusted by screwing in or out the adjusting screw 19, which is relatively simple and convenient to operate.

[0031] As shown, a discharge trough 24 is provided on the top of the front clamping mechanism 3, and a feed trough 25 is provided on the top of the rear clamping mechanism 4. The zipper head enters and is clamped in the clamping trough 12 through the feed trough 11, and is finally discharged through the discharge trough 24. The discharge trough 24 includes a first discharge trough 26 and a second discharge trough 27. A guide block 28 is provided on the second discharge trough 27. A first discharge channel 29 and a second discharge channel 30 are formed between the side walls of the guide block 28 and the second discharge trough 27. During the discharge of the zipper head, the guide block 28 can play a guiding role and can guide the zipper head to smoothly enter the first discharge channel 29 or the second discharge channel 30. The design of the two discharge channels reduces the burden of the machine when it is running at high speed, and it can be discharged through any discharge channel. The first discharge channel 29 and the second discharge channel 30 meet in the first discharge trough 26. The zipper head passes through the first discharge channel 29 or the second discharge channel 30, and then is discharged through the first discharge trough 26 to enter the next process. The width of the first discharge slot 26 is smaller than that of the second discharge slot 27. A guide surface 31 is provided between the first discharge slot 26 and the second discharge slot 27. The guide surface 31 is an inclined surface, which helps the zipper head to enter the first discharge slot 26 from the first discharge channel 29 or the second discharge channel 30, thereby playing a guiding role.

[0032] The center of the top surface of the front lifting block 6 and the rear lifting block 7 is provided with an inner concave portion 20, and the hanging tag of the zipper head is clamped downward in the clamping groove 8, and the hanging piece of the zipper head is located in the interior 20 to prevent the hanging piece from shaking at will and causing inconvenience to the user.

[0033] The moving mechanism 2 shown includes a slide rail 21 fixed on the base 1 and a slider 22 installed on the upper end of the slide rail 21, and a cylinder 23 installed on one side of the front clamping mechanism 3. The slider 22 can slide on the slide rail 21. The gas rod of the cylinder 23 passes through the front clamping mechanism 3 and is connected to the slider 22. The rear clamping mechanism 4 is installed on the upper end of the slider 22. The slider 8 is driven to move laterally through the contraction of the gas rod of the cylinder 23, and the rear clamping mechanism 4 is driven to move laterally at the same time, so as to clamp or release the zipper head.
