Description

Technical Field

[0001] The utility model belongs to the field of zipper machine equipment and relates to a latch chain-splitting moving device with an inclined groove. Technical Background

[0002] The traditional zipper molding method first molds the lower stop of the chain, then completes the upper pull head action through the chain threading machine, and then molds the front upper stop, so it requires two injection moldings. Now this bevel upper pull head process can mold the upper stop and lower stop at one time, and then mold the bevel on the chain upper stop with a square, and complete the upper pull head work through the bevel, reducing the process steps and shortening the production line length.

[0003] After putting on the pull head on the split chain with the block, a chain paralleling process is required to parallel the block split chain and the pin split chain. Chinese invention patent ZL202311597528.7, the patent name is a chain threading and paralleling integrated machine with an oblique stop belt on a chain belt, which discloses a chain paralleling method with an oblique stop belt on a chain belt, positioning the block position through a block positioning device, moving the split chain with a pin backward through a rear traction device, so that the originally co-located pin and block are misaligned, and the pin is moved backward to the rear side of the block, and the split chain with a pin is moved up, down, left, and right through the pin split chain moving plate, so that the pin is aligned with the socket of the block and the pull head, and then the aligned pin is inserted into the socket through the front traction device, and then the chain belt is pulled forward through the front traction device to realize the chain paralleling process. This method can realize the automation of chain paralleling of the oblique chain belt, but it has a complex structure, complex steps, high production cost, and low work efficiency. Summary of the invention

[0004] In view of the above problems, the present invention provides a latch chain moving device with an inclined groove, which has the advantages of simple structure, simplified chaining steps, reduced production costs and improved production efficiency.

[0005] The purpose of the utility model is achieved in this way:

[0006] A latch chain moving device with an inclined groove comprises a latch chain moving plate and a driving mechanism for driving the latch chain moving plate to move left and right, the latch chain moving plate comprises an upper plate and a lower plate, a latch chain slide groove running through front and back is provided between the upper plate and the lower plate, a latch notch is provided on the outer side of the front end of the latch chain moving plate, an inclined groove is provided on the inner side of the front part of the latch chain slide groove, and the inclined groove is inclined downward away from the latch notch.

[0007] By setting the inclined groove, the cloth bag in front of the latch is folded upward to a higher level than the latch. When the driving mechanism moves the latch chain moving plate to the set position so that the latch is aligned with the socket of the slider, the folded cloth bag will be against the side of the slider and will not enter the slider. Then the latch is inserted into the socket of the slider through the chain belt traction device, thereby completing the chain connection.

[0008] The utility model is further configured as follows: the inner side of the front end of the lower plate is tilted downward to form a lower inclined surface, the inner side of the front end of the upper plate is also tilted downward to form an upper inclined surface, and an inclined groove is formed between the upper inclined surface and the lower inclined surface.

[0009] The utility model is further configured as follows: the lower inclined surface and the upper inclined surface are both triangles.

[0010] The utility model is further configured as follows: the two sides of the lower inclined surface connecting the inclined angle are respectively arranged on the front end surface and the inner side surface of the latch pin chain slot, and the two sides of the upper inclined surface connecting the inclined angle are also respectively arranged on the front end surface and the inner side surface of the latch pin chain slot.

[0011] The above arrangement is to reduce the area of ​​the upper inclined surface and the lower inclined surface, so that the inclined surface is triangular, thereby reducing the inclined area and facilitating the molding of the upper plate and the lower plate.

[0012] The utility model is further configured as follows: a hinge seat is fixed on the lower plate, a hinge shaft is arranged in the hinge seat, a hinge groove is arranged on the upper plate, hinge holes are arranged on both sides of the hinge groove, and the hinge shaft on the hinge seat passes through the hinge holes on the hinge groove to realize hinge.

[0013] By hingedly arranging the upper plate and the lower plate, the upper plate can be opened to facilitate the installation of the latch chain.

[0014] The utility model is further configured as follows: a torsion spring is sleeved on the hinge shaft, one end of the torsion spring abuts against the upper plate, and the other end abuts against the lower plate, and the torsion spring applies a pre-tightening force to press the upper plate downward.

[0015] By setting the torsion spring, the upper plate can always have a pre-tightening force to press the lower plate, so as to prevent the upper plate from loosening and opening during the movement of the latch chain.

[0016] The utility model is further configured as follows: the driving mechanism comprises a cylinder fixed on the bracket, the extended end of the cylinder is rotatably connected to the front end of the lower plate, and the rear end of the lower plate is rotatably connected to the fixing seat.

[0017] Through the above arrangement, the latch chain moving plate is controlled to move the latch chain in a swinging manner. Compared with the overall horizontal movement of the latch chain moving plate (large deformation is generated at the latch chain inlet, large shear force is generated, and it is easy to deform), the swinging manner generates less shear force on the latch chain, which is not easy to deform and is more conducive to the stability of transportation.

[0018] The utility model is further configured as follows: the lower plate is "L"-shaped and comprises a horizontal section and a vertical section, the extended end of the cylinder is hinged to the front end of the horizontal section, and the vertical section of the lower plate is rotatably connected to the fixing seat through a pin shaft.

[0019] The utility model is further configured as follows: the latch chain-dividing slide groove comprises a chain tooth slide groove and a chain belt slide groove, half of the chain tooth slide groove is arranged on the upper plate and half is arranged on the lower plate, and the notch is arranged on the front end of the chain tooth slide groove.

[0020] The utility model is further configured as follows: the front end of the side wall of the chain tooth slide groove is inclined toward the outside.

[0021] Through the above arrangement, the latch can be tilted toward the slider at a slight angle, making it easier for the latch to be inserted into the slider.

[0022] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects: after the chain threading device passes the pull head through the oblique opening into the block chain to complete the chain threading, the chain belt traction device tractions the chain belt to the set position, at which time the blocks on the block chain are fixed, the latch of the latch chain is at the latch notch, and the blade in front of the latch is in front of the latch chain slide (in an unobstructed state), and through the setting of the inclined groove, the cloth bag in front of the latch (across the blade) is folded up and tilted at a certain angle, so that the cloth bag in front of the latch is higher than the horizontal position of the latch after folding, and then the driving mechanism sends the latch chain moving plate to the set position, so that the latch is aligned with the plug of the pull head, because the cloth bag in front of the latch is higher than the horizontal position of the latch after folding, the cloth bag in front of the latch will not enter the pull head, but will be deformed against the side of the pull head, and finally the latch is inserted into the plug of the pull head through the chain belt traction device, thereby completing the chaining. Compared with the prior art, this method not only reduces multiple components and reduces production costs, but also reduces process steps and improves production efficiency.

[0034] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0035] The chain belt 10 includes a block sub-chain 101 and a latch sub-chain 102. The block sub-chain 101 is provided with a block 103 in front and an upper stop 105 in the rear. The upper stop 105 has an oblique opening 106 for passing the slider. The latch sub-chain 102 is provided with a latch 104 in front and an upper stop 105 in the rear. The upper stop 105 has no oblique opening. The block sub-chain 101 and the latch sub-chain 102 of each section of the chain belt are provided with a knife edge 107 in front. The knife edge 104 is conducive to the deformation of the cloth bag 109 at the knife edge, so as to facilitate the latch to enter the slider.

[0036] A latch chain moving device with an inclined groove comprises a latch chain moving plate 1 and a cylinder 2 for driving the latch chain moving plate 1 to move left and right, the latch chain moving plate 1 comprises an upper plate 11 and a lower plate 12, a latch chain sliding groove 13 which passes through the upper plate 11 and the lower plate 12, a latch notch 14 is arranged on the outer side of the front end of the latch chain moving plate 1, an inclined groove 15 is arranged on the inner side of the front part of the latch chain sliding groove 13, and the inclined groove 15 is inclined downward away from the latch notch 14.

[0037] After the chain threading device passes the pull head through the oblique opening into the block chain 101 to complete the chain threading, the chain belt traction device pulls the chain belt to the set position. At this time, the block 103 on the block chain 101 is fixed, the latch 104 of the latch chain 102 is at the latch notch 14 of the latch chain moving plate 1, and the knife edge 107 in front of the latch 104 is in front of the latch chain slide groove 13 (in an unobstructed state). Through the setting of the inclined groove 15, the cloth bag 109 in front of the latch 104 (separated by the knife edge) is folded upward and tilted. At a certain angle, the cloth bag 109 in front of the latch 104 is folded to be higher than the horizontal position of the latch 104, and then the cylinder 2 sends the latch chain moving plate 1 to the set position, so that the latch 104 is aligned with the socket of the slider. Since the cloth bag 109 in front of the latch 104 is higher than the horizontal position of the latch 104 after being folded, the cloth bag 109 in front of the latch 104 will not enter the slider, but will be deformed against the side of the slider. Finally, the latch 104 is inserted into the socket of the slider through the chain belt traction device, thereby completing the chain connection.

[0038] The front inner side of the lower plate 12 is tilted downward to form a lower tilted surface 16, and the front inner side of the upper plate 11 is also tilted downward to form an upper tilted surface 17, and an inclined groove 15 is formed between the upper tilted surface 17 and the lower tilted surface 16. The lower tilted surface 16 and the upper tilted surface 17 are both triangular.

[0039] The two sides of the lower inclined surface 16 connecting the inclined angle are respectively arranged on the front end face 131 and the inner side face 132 of the latch pin chain chute 13, and the two sides of the upper inclined surface 17 connecting the inclined angle are also respectively arranged on the front end face 131 and the inner side face 132 of the latch pin chain chute 13. The above arrangement is to reduce the area of ​​the upper inclined surface 17 and the lower inclined surface 16, so that the inclined surface is triangular, thereby reducing the area of ​​the inclined surface, and facilitating the molding of the upper plate 11 and the lower plate 12.

[0040] The lower plate 12 is fixed with an articulation seat 31, in which an articulation shaft 32 is arranged, and the upper plate 11 is provided with an articulation groove 33, and articulation holes 34 are arranged on both sides of the articulation groove 33. The articulation shaft 32 on the articulation seat 31 passes through the articulation holes 34 on the articulation groove 33 to achieve articulation. By articulating the upper plate 11 and the lower plate 12, the upper plate can be opened to facilitate the installation of the latch chain 102.

[0041] The hinge shaft 32 is sleeved with a torsion spring 35, one end of which is against the upper plate 11 and the other end is against the lower plate 12. The torsion spring 35 applies a pre-tightening force to press the upper plate 11 downward. By providing the torsion spring 35, the upper plate 11 can always have a pre-tightening force to press the lower plate 12, thereby preventing the upper plate from loosening and opening during the movement of the latch chain 102.

[0042] The driving mechanism includes a cylinder 2 fixed on the bracket, the extended end 21 of the cylinder 2 is rotatably connected to the front end of the lower plate 12, and the rear end of the lower plate 12 is rotatably connected to the fixed seat 22. Through the above arrangement, the latch chain moving plate 1 controls the movement of the latch chain 102 in a swinging manner. Compared with the overall horizontal movement of the latch chain moving plate 1 (large deformation and large shear force are generated at the inlet of the latch chain moving plate 1), the swinging manner generates less shear force on the latch chain and is not easy to deform, which is more conducive to the stability of transportation.

[0043] The lower plate 12 is "L" shaped and comprises a horizontal section 121 and a vertical section 122. The extended end 21 of the cylinder 2 is hinged to the front end of the horizontal section 121, and the vertical section 122 of the lower plate is rotatably connected to the fixing seat 22 via a pin shaft 23.

[0044] The latch chain slot 13 includes a chain tooth slot 133 and a chain belt slot 134 . The chain tooth slot 133 is half arranged on the upper plate 11 and half arranged on the lower plate 12 . The latch notch 14 is arranged at the front end of the chain tooth slot 134 .

[0045] The front end of the side wall 135 of the chain tooth slideway is inclined toward the outside. Through the above arrangement, the latch 104 can be tilted toward the slider at a certain angle, making it more convenient for the latch to be inserted into the slider.

[0046] The utility model has the characteristics of simple structure, simplified chaining steps, reduced production cost and improved production efficiency.

[0047] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
