Description

Technical Field

[0001] This invention relates to the field of zipper device technology, and specifically to a zipper device with an easy-pull structure and its production equipment. Background Technology

[0002] Zippers consist of teeth, a slider, top and bottom stops or locking components, etc. As an item used in daily life to connect or close pockets, zippers can quickly open pockets or clothes, making it easier for people to put on and take off clothes.

[0003] According to patent number CN202110832122.7, it not only has an easy-pull function, but also makes it easy for the zipper head to be pulled on the entire zipper device. It provides sliding friction through rolling friction, resulting in low overall pulling friction resistance and easy movement.

[0004] However, during use, we found that the zipper teeth of the aforementioned patent still have problems such as being too rough and easily snagging on clothing or other items, causing discomfort when worn. At the same time, the exposed side of the zipper head can easily scratch other clothing and get stuck when sliding, making it difficult to pull. Furthermore, the use of ball bearings to reduce friction is not only difficult to manufacture, but also the ball bearings can become more resistant to friction due to impurities after prolonged use, which can affect the use of the zipper and make it difficult to slide. Summary of the Invention

[0005] The purpose of this invention is to provide a zipper device with an easy-pull structure and its production equipment. The structure is simple and easy to produce, while also concealing the problem of exposed zipper head sides, further reducing the problem of clothing being clamped or hooked due to exposure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a zipper, comprising a nylon braided tape, a main zipper plate, zipper teeth, and a zipper head slidably disposed between the zipper teeth, wherein the top of the main zipper plate is provided with sliding grooves, and symmetrically arranged sliding plates on the zipper head are slidably disposed within the sliding grooves, and metal guide plates are linearly arranged within the sliding grooves.

[0007] Preferably, the zipper teeth are fixedly installed on the outer wall of the two main zipper plates on adjacent sides. The zipper teeth include curved heads arranged in a linear array. The two curved head supports are provided with curved grooves, and the curved grooves are provided with recessed portions. The protrusion provided on one of the curved heads is driven to engage with the recessed portion on the other zipper tooth.

[0008] Preferably, the zipper head includes a mounting plate, and the sliding plate is symmetrically and fixedly mounted on the bottom of the mounting plate. The sliding groove is a triangular groove with a cross-section, and the sliding plate matches the triangular groove with a cross-section.

[0009] Preferably, a curved guide plate is fixedly installed at the bottom of the mounting plate, and a lower support plate is provided below the curved guide plate. A connecting rod is directly fixedly installed on the curved guide plate and the lower support plate, and the first end of the connecting rod is fixedly installed at the bottom of the mounting plate. The zipper teeth are respectively movably arranged between the curved guide plate and the lower support plate, and the two zipper teeth mesh with each other.

[0010] Preferably, a horizontal guide plate is symmetrically arranged at one end of the lower support plate, and guide rails are symmetrically opened on the outer wall of the two main zipper plates on adjacent sides. U-shaped guide plates are linearly arrayed and fixedly installed in the guide rails, and the horizontal guide plates are slidably arranged on the U-shaped guide plates respectively.

[0011] Preferably, hooks are symmetrically arranged on the outer walls of the U-shaped guide plate on both sides near the U-shaped port. The U-shaped guide plate is inserted into the guide rail, and the hooks are fixedly installed on both sides of the guide rail port. The outer walls of the U-shaped guide plate on both sides are symmetrically arranged with protrusions.

[0012] Preferably, the top of the mounting plate is symmetrically provided with a locking plate and a guide post, and a mounting block is inserted into the locking plate and the guide post. The mounting block has a storage slot, and a pull plate is inserted into the storage slot.

[0013] A production device includes the zipper described in the above-mentioned solution, including a worktable and a guide rail opened on the worktable, and a mounting plate is slidably disposed in the guide rail, and also includes a lower pressing platform, the bottom of which is adsorbed with a mounting block, and the lower pressing platform is driven to make the mounting block insert into a locking plate and a guide post.

[0014] Preferably, the bottom of the pressing platform is provided with a slot, and a magnetic magnet is fixedly installed on the inner wall of the slot, and the mounting block is attracted to the magnetic magnet.

[0015] Preferably, the locking plate is a resilient metal plate.

[0016] In the above technical solution, the present invention has the following beneficial effects: the zipper head located between the zipper teeth drives the zipper teeth to open and close, while the symmetrically arranged sliding plates on the zipper head are slidably disposed in the sliding groove, thereby hiding the sliding plates on the side of the zipper head, so as to avoid the inconvenience of pulling the zipper head when the clothes are hooked when it slides. At the same time, the metal guide plates arranged in a linear array in the sliding groove facilitate the sliding of the zipper head by the low friction of the metal itself, thereby making it easier to pull the zipper head.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-7As shown, a zipper device with an easy-open structure and its production equipment include a nylon braided tape 2, a main zipper plate 1, zipper teeth, and a zipper head slidably disposed between the zipper teeth. The top of the main zipper plate 1 is provided with sliding grooves 35, and symmetrically arranged sliding plates 54 on the zipper head are slidably disposed within the sliding grooves 35. Metal guide plates 36 are linearly arranged within the sliding grooves 35. The zipper head, located between the zipper teeth, drives the zipper teeth to open and close. Simultaneously, the symmetrically arranged sliding plates 54 on the zipper head are slidably disposed within the sliding grooves 35, thus concealing the sliding surface of the sliding plates 54 on the side of the zipper head. This prevents the zipper head from being difficult to pull when hooking clothing. Furthermore, the linearly arranged metal guide plates 36 within the sliding grooves 35 facilitate the sliding of the zipper head through the low friction of the metal itself, thereby making it easier to pull the zipper head.

[0029] like Figure 1 As shown, as a further technical solution provided by the present invention, in order to enable the two zipper teeth to quickly engage, the zipper teeth are respectively fixedly installed on the outer wall of the adjacent side of the two main zipper plates 1. The nylon braided tape 2 serves as a flexible tape to connect the main zipper plates 1 to clothing or other items. The zipper teeth include curved heads 3 arranged in a linear array. The supports of the two curved heads 3 are provided with curved grooves 31, and the curved grooves 31 are provided with recesses 32. By making the curved heads 3 on the two main zipper plates 1 staggered and making the curved heads 32 staggered, the zipper teeth can achieve rapid engagement. The curved head 3 is located on one side of the groove 32 on another main zipper plate 1. By sliding the two main zipper plates 1 onto the zipper head respectively, the curved head 3 is driven and engaged in the curved groove 31 in sequence, so that the two main zipper plates 1 are connected to each other. At the same time, the protrusion 33 provided on one of the curved heads 3 is driven and engaged in the groove 32 on the other zipper tooth. The protrusion 33 is engaged in the groove 32, thereby reducing the likelihood of the curved head 3 of the two main zipper plates 1 being dislodged from the curved groove 31.

[0030] Furthermore, to prevent the slide plate 54 from slipping off the sliding groove 35, the zipper head includes a mounting plate 4, and the slide plate 54 is symmetrically fixedly installed on the bottom of the mounting plate 4. The sliding groove 35 is a triangular groove with a cross-section, and the slide plate 54 matches the triangular groove with a cross-section. Specifically, the slide plate 54 includes a side plate and a triangular rod with a cross-section located at the bottom of the side plate. The triangular rod slides in the triangular groove with a cross-section, thereby preventing the slide plate 54 from slipping off the sliding groove 35. At the same time, the main zipper plate 1 is a flexible plastic plate. Therefore, in order to reduce the friction between the slide plate 54 and the sliding groove 35, the slide plate 54 and the metal guide plate 36 are smooth metal surfaces. The metal guide plate 36 can greatly reduce the friction between the slide plate 54 and the sliding groove 35. Moreover, the metal guide plate 36 is arranged in a linear array, so the main zipper plate 1 can be bent to a certain extent, which enhances its flexibility.

[0031] Furthermore, in order to guide the two main zipper plates 1 to engage and disengage, a curved guide plate 5 is fixedly installed at the bottom of the mounting plate 4, and a lower support plate 52 is provided below the curved guide plate 5. A connecting rod 51 is directly fixedly installed on the curved guide plate 5 and the lower support plate 52, and the first end of the connecting rod 51 is fixedly installed at the bottom of the mounting plate 4. The zipper teeth are respectively movably arranged between the curved guide plate 5 and the lower support plate 52, and the two zipper teeth mesh with each other, thereby enabling the two main zippers to engage and disengage. The curved heads 3 on plate 1 slide on both sides of the connecting rod 51 and slide between the curved guide plate 5 and the lower support plate 52 under the guidance of the connecting rod 51. Then, when the slide plate 54 slides in the sliding groove 35, it drives the two main zipper plates 1 to move closer to each other, thereby squeezing the main zipper plates 1 located between the curved guide plate 5 and the lower support plate 52 to engage with each other. When the connecting rod 51 moves in the opposite direction, the connecting rod 51 pushes the two main zipper plates 1 to drive the two main zipper plates 1 to separate from each other.

[0032] Furthermore, to ensure the stability of the skateboard 54 when sliding within the sliding groove 35, a horizontal guide plate 53 is symmetrically arranged at the end of the lower support plate 52 away from the connecting rod 51. Guide rails are symmetrically opened on the outer walls of the two main zipper plates 1 on adjacent sides. U-shaped guide plates 34 are linearly arrayed and fixedly installed in the guide rails. The horizontal guide plates 53 are slidably arranged on the U-shaped guide plates 34 respectively. By using the horizontal guide plates 53 to slide on the U-shaped guide plates 34 respectively, the stability of the skateboard 54 when sliding within the sliding groove 35 is improved, thereby reducing the force on the skateboard 54 when sliding and avoiding deformation due to excessive force, which would affect subsequent use.

[0033] More specifically, in order to install the U-shaped guide plate 34, hooks 37 are symmetrically arranged on the outer walls of the U-shaped guide plate 34 near the U-shaped port on both sides. The main zipper plate 1 is fixed by the equipment, and the U-shaped guide plate 34 is pushed into the guide rail by the equipment. At this time, the hooks 37 are inserted into the slots on both sides of the guide rail for fixing, thereby making the U-shaped guide plate 34 fixed on the main zipper plate 1. At the same time, protrusions 38 are symmetrically arranged on the outer walls of the U-shaped guide plate 34 on both sides. When the U-shaped guide plate 34 is pushed into the guide rail, the protrusions 38 push against the inner wall of the guide rail, thereby making the U-shaped guide plate 34 more firmly located in the guide rail.

[0034] like Figure 4 As shown, for the zipper head, the top of the mounting plate 4 is symmetrically provided with a locking plate 41 and a guide post 42. Mounting blocks 43 are inserted into the locking plate 41 and the guide post 42. The mounting block 43 is provided with a storage groove 44. Elastic pieces 45 are symmetrically fixedly installed on the inner walls of the storage groove 44 on both sides. A pull plate 46 is inserted into the storage groove 44. By sliding the shaft 47 on the pull plate 46 between the two elastic pieces 45, and moving it to the bottom of the storage groove 44 with the sliding shaft 47, the pull plate 46 can be quickly installed on the mounting block 43 under the cover of the elastic pieces 45.

[0035] like Figure 7 As shown, the production equipment for processing zipper heads includes a worktable 6 and guide rails 61 symmetrically arranged on the worktable 6. The two sides of the mounting plate 4 are slidably arranged in the guide rails 61. The equipment also includes a pressing platform 7. The bottom of the pressing platform 7 is used to attract the mounting block 43, and the pressing platform 7 is pushed by a hydraulic cylinder to make the mounting block 43 insert into the locking plate 41 and the guide post 42. When the mounting block 43 is pressed down on the locking plate 41 and the guide post 42, the locking plate 41 is inserted into the slots 48 symmetrically arranged on the mounting block 43. At this time, the locking plate 41 deforms and its buckle is engaged in the slot in the slot 48 when it slides in the slot 48, thereby making the locking plate 41 engage with the mounting block 43. At this time, the guide post 42 slides into the guide groove 49 on the mounting block 43 as the mounting block 43 is pressed down, thereby reducing the sliding of the mounting block 43 to the top of the mounting plate 4.

[0036] Furthermore, to enable the bottom of the pressing platform 7 to quickly attract the mounting block 43, a slot is provided at the bottom of the pressing platform 7. A magnet 71 is fixedly installed on the inner wall of the slot. By pressing down on the pressing platform 7, the mounting block 43 is made to snap into the slot and be attracted to the magnet 71. When the mounting block 43 is engaged with the locking plate 41, the pressing platform 7 is disengaged from the mounting block 43. At this time, the mounting plate 4 slides into the guide rail 61, so that the next mounting plate 4 can move to the pressing position. Specifically, regarding the sliding of the mounting plate 4... The guide rail 61 can be moved by a motor in conjunction with a rotating wheel and a transmission belt on the rotating wheel. The transmission belt, in conjunction with the servo motor, rotates at a fixed angle to move the mounting plate 4 a certain distance, thereby causing the lower pressure table 7 to press down and install the mounting block 43. At the same time, a hydraulic cylinder can be installed on the lower pressure table 7 to drive the lower pressure table 7 to press down, and in conjunction with the motor, drive the lower pressure table 7 to rotate and engage the mounting block 43 in the slot, and then rotate and press down again to install the mounting block 43 on the mounting plate 4.

[0037] Specifically, considering that the locking plate 41 will deform under stress, the locking plate 41 is an elastic metal plate.

[0038] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
