Description

Technical Field

[0001] This utility model belongs to the field of zipper machine equipment and relates to a chain belt angle splitting device for a chain belt threading machine. Background Technology

[0002] A chain threading machine is a device that automatically threades a pull head onto a chain. For example, a chain threading machine disclosed in Chinese Invention Patent No. 202410401973.X includes a chain guide platform mounted on a frame, a chain traction mechanism, an upper pull head mold, and an upper stop positioning mechanism. The upper pull head mold includes an upper pull head cylinder and a pull head base. The pull head base has a pull head cavity formed on it. A dividing needle is fixed in front of the pull head cavity. The vertical distance from the outer side of the dividing needle to the center line of the pull head is greater than the vertical distance from the outer side of the pull head to the center line. Because there is a triangular dividing needle inside the pull head, the upper stop can easily get stuck when passing through it. Therefore, by using the dividing needle in front of the pull head cavity, and given that the vertical distance from the outer side of the dividing needle to the center line of the pull head is greater than the vertical distance from the outer side of the pull head to the center line, the chain in front of the upper stop is shifted to the side at an angle that allows the upper stop to avoid the triangular dividing needle, preventing the triangular dividing needle from getting stuck on the upper stop. However, in this method, the minute hand and the slider move synchronously. When the slider moves upward, the minute hand also moves upward. At this time, the minute hand will separate the chain from the bottom up, thus pushing the chain upward at an angle. And because the minute hand and the slider are synchronized, the chain will remain in an upward-push state during the chain threading process. This can easily cause the pin to deviate when inserting into the block, resulting in it not being able to be inserted. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a chain belt splitting device for a chain belt threading machine. This device has a splitting pin and a pull head seat that operate independently. When the upper stop of the block chain is inserted into the pull head, the splitting pin will rise and reset, leaving the chain belt. Thus, when the pull head moves to the block and the pin is inserted, the accuracy of the pin insertion will not be affected.

[0004] The purpose of this utility model is achieved as follows:

[0005] A chain belt splitting device for a chain belt threading machine includes an upper stop positioning mechanism. An upper pull head mold is provided below the upper stop positioning mechanism. The upper stop positioning mechanism includes a slide block. A splitting pin seat is fixed at the front end of the slide block. A splitting cylinder is fixed on the splitting pin seat. The output end of the splitting cylinder extends downward and is fixedly connected to a splitting pin. The upper pull head mold includes a pull head seat. A pull head groove is provided on the pull head seat. After the upper pull head mold rises, the pull head groove is located on the path of the chain belt, and the splitting pin is located in front of the pull head groove.

[0006] With the above settings, once the upper stop positioning mechanism has positioned the upper stop, the upper pull head mold rises and enters between the two chain branch points. At this time, the angle-dividing cylinder controls the angle-dividing pin to move from top to bottom, shifting the chain in front of the upper stop to the side at an angle that allows the upper stop to avoid the triangular chain branch pin, preventing the triangular chain branch pin from jamming the upper stop. After the upper stop successfully enters the pull head, the angle-dividing cylinder controls the angle-dividing pin to rise and reset, and the chain continues to move forward until the block reaches the rear end of the pull head. Then, the pin of the pin branch is inserted into the pull head and the block. Because the angle-dividing pin and the pull head mold operate independently, the angle-dividing pin has already left the chain when the pin is inserted, preventing chain deformation and thus not affecting the accuracy of the pin insertion.

[0007] The present invention is further configured such that: the dividing needle extends into a dividing portion on one side of the fabric tape of the square chain, and the width of the dividing portion is greater than half the width of the zipper head.

[0008] With the above settings, the corner pin can shift the block chain to the side at a larger angle, allowing the top stop to better avoid the triangular chain pin and making it easier to insert the top stop into the pull head.

[0009] The present invention is further configured such that: the dividing part includes a transition section and a stop section, the transition section being larger at the top and smaller at the bottom and connected to the stop section from the lower end of the dividing needle.

[0010] With the above settings, the dividing pin can gradually open the chain through the transition section, playing a role in buffering and protecting the chain.

[0011] The present invention is further configured such that: a connecting block is fixedly connected to the output end of the angle-dividing cylinder, and the lower end of the connecting block is fixedly connected to the upper end of the angle-dividing needle.

[0012] The present invention is further configured such that: the angle-dividing needle seat is formed with a vertical through groove, the output end of the angle-dividing cylinder and the connecting block are disposed in the vertical through groove, and the shape of the connecting block is adapted to the vertical through groove.

[0013] By adapting the shape of the connecting block to the vertical through groove, the connecting block not only connects the output end of the angle cylinder and the angle needle, but also acts as a guide, making the movement of the angle needle more stable.

[0014] The present invention is further configured such that: the upper end of the dividing pin is provided with a fixing part, the lower end side wall of the connecting block is formed with a fixing groove, the fixing part extends a fixing protrusion toward the fixing groove, the fixing protrusion is disposed in the fixing groove, and the fixing part is fixedly connected to the connecting block by bolts.

[0015] The above settings enable a more stable connection between the angle pin and the connecting block, preventing the angle pin from rotating.

[0016] The present invention is further configured such that: the upper end of the pull head seat is provided with a smoothing end face on the side of the cloth tape facing the block branch chain.

[0017] By smoothing the end face, when the dividing pin is inserted from top to bottom, the smoothed end face can prevent the part of the chain near the zipper from deforming excessively downwards. This further improves the stability of the top stop insertion into the zipper.

[0018] The significant and beneficial technical advantages of this invention compared to existing technologies are as follows: After the upper stop positioning mechanism positions the upper stop, the upper pull head mold rises and enters between the two chain branch points. At this time, the angle-dividing cylinder controls the angle-dividing pin to move downwards, shifting the chain in front of the upper stop to the side at an angle that allows the upper stop to avoid the triangular chain branch pin, preventing the triangular chain branch pin from jamming the upper stop. After the upper stop successfully enters the pull head, the angle-dividing cylinder controls the angle-dividing pin to rise and reset, and the chain continues to move forward until the block reaches the rear end of the pull head. Then, the pin of the pin branch is inserted into the pull head and the block. Because the angle-dividing pin and the pull head mold operate independently, the angle-dividing pin has already left the chain when the pin is inserted, preventing chain deformation and thus ensuring the accuracy of the pin insertion.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] A chain belt splitting device for a chain belt threading machine includes an upper stop positioning mechanism 1, with an upper pull head mold 2 located below the upper stop positioning mechanism 1. Both the upper stop positioning mechanism 1 and the upper pull head mold 2 are existing technologies and will not be described in detail here. The upper stop positioning mechanism includes a slide 3, and a splitting pin seat 4 is fixed to the front end of the slide 3. A splitting cylinder 5 is fixed to the upper part of the splitting pin seat 4. The output end 6 of the splitting cylinder extends downward and is fixedly connected to a splitting pin 7. The upper pull head mold includes a pull head seat 8, and a pull head groove 9 is provided on the pull head seat 8. After the upper pull head mold rises, the pull head groove 9 is located on the path of the chain belt, and the splitting pin 7 is located in front of the pull head groove 9.

[0031] With the above settings, once the upper stop positioning mechanism has positioned the upper stop, the upper pull head mold raises the pull head 10 between the two chain segments. At this time, the angle-dividing cylinder 5 controls the angle-dividing pin 7 to move downwards, shifting the chain in front of the upper stop to the side at an angle that allows the upper stop to avoid the triangular chain-dividing pin 11, preventing the triangular chain-dividing pin 11 from jamming the upper stop. After the upper stop successfully enters the pull head, the angle-dividing cylinder 5 controls the angle-dividing pin 7 to rise and reset, and the chain continues to move forward until the block reaches the rear end of the pull head. Then, the pin of the pin-separated chain is inserted into the pull head and the block. Since the angle-dividing pin 7 and the upper pull head mold operate independently, the angle-dividing pin has already left the chain when the pin is inserted, preventing chain deformation and thus not affecting the accuracy of the pin insertion.

[0032] The dividing pin 7 extends into a dividing portion 12 towards the side of the square chain strap, and the width of the dividing portion 12 is greater than half the width of the zipper pull. This design allows the dividing pin to shift the square chain strap to the side at a larger angle, thus allowing the top stop to better avoid the triangular chain strap pin and making it easier to insert the top stop into the zipper pull.

[0033] The dividing section 12 includes a transition section 13 and a stop section 14. The transition section 13 is wider at the top and narrower at the bottom, and is connected to the stop section 14 from the lower end of the dividing pin 7. With the above arrangement, the dividing pin 7 can gradually open the chain through the transition section 13, which plays a role in buffering and protecting the chain.

[0034] The output end 6 of the angle-dividing cylinder is fixedly connected to a connecting block 15, and the lower end of the connecting block 15 is fixedly connected to the upper end of the angle-dividing needle 7.

[0035] The angle-dividing needle seat 4 has a vertical through groove 16. The output end 6 of the angle-dividing cylinder and the connecting block 15 are disposed in the vertical through groove 16, and the shape of the connecting block 15 is adapted to the shape of the vertical through groove 16. By adapting the shape of the connecting block 15 to the vertical through groove 16, the connecting block 15 not only serves to connect the output end 6 of the angle-dividing cylinder and the angle-dividing needle 7, but also serves as a guide, making the movement of the angle-dividing needle 7 more stable.

[0036] The upper end of the angle pin 7 is provided with a fixing part 17, and the lower end side wall of the connecting block 15 is formed with a fixing groove 18. The fixing part 17 extends a fixing protrusion 19 toward the fixing groove 18, and the fixing protrusion 19 is disposed in the fixing groove 18. The fixing part 17 is fixedly connected to the connecting block by bolts. With the above configuration, the angle pin 7 and the connecting block 15 can be connected more stably, and the angle pin 7 is not easy to rotate.

[0037] The upper end of the zipper head 8, facing the side of the fabric tape of the block-shaped chain, is provided with a smoothing end face 20. By providing the smoothing end face 20, when the dividing pin 7 is inserted from top to bottom, the smoothing end face 20 can prevent the part of the chain tape near the zipper head from deforming excessively downwards. This further improves the stability of the zipper head insertion.

[0038] This invention features an independent operation of the dividing pin and the pull head seat. When the upper stop of the block chain is inserted into the pull head, the dividing pin will rise and reset, leaving the chain. Thus, when the pull head moves to the block and the pin is inserted, the accuracy of the pin insertion will not be affected.

[0039] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
