Description

Technical Field

[0001] This invention relates to the field of hook and loop fastener production technology, specifically to a hook and loop fastener forming apparatus and its usage method. Background Technology

[0002] Hook and loop fasteners, as a convenient connecting accessory, are widely used in clothing, bags, medical supplies, daily necessities, industrial parts, and other fields due to their advantages such as simple operation, reliable connection, and high reusability. In the large-scale production process of hook and loop fasteners, the formed hook and loop fasteners need to undergo subsequent processes such as slitting, winding, cutting, and transfer to form finished rolls that meet market demands. Among these processes, the winding device is the core equipment connecting the forming and subsequent processing.

[0003] After the hook and loop fastener is wound to the preset length, it needs to be cut. In traditional devices, the winding and cutting processes are mostly operated independently. It is necessary to manually pause the winding, align the cutting line, and cut manually. This is not only cumbersome and time-consuming, but also prone to causing the cut edge to tilt and the length of the roll to be too far due to manual intervention. Some automated devices lack precise guidance and blade retraction protection in their cutting structure, which can easily damage the surface structure of the hook and loop fastener or cause blade jamming during cutting.

[0004] Traditional winding devices rely heavily on manual alignment and installation of the winding rollers, which is difficult to operate, has low positioning accuracy, and is labor-intensive. After winding, unwinding and transferring the material requires manual disassembly of the winding rollers and transportation to the storage area. This process can easily lead to loosening of the rolled material and surface wear. At the same time, frequent manual intervention severely restricts production continuity and is difficult to adapt to the needs of large-scale production.

[0005] After winding, the hook and loop fastener rolls must maintain a regular shape to prevent deformation and tangling during subsequent storage and transportation. Existing equipment lacks a dedicated support and transfer structure, and the rolls are often directly stacked after unloading, which can easily lead to roll collapse and edge damage. Furthermore, there is no partitioning or isolation design when transferring multiple rolls, resulting in mutual squeezing and friction, which further affects product quality. Summary of the Invention

[0030] (III) Beneficial Effects

[0031] Compared with the prior art, the present invention provides an apparatus for forming hook and loop fasteners and a method for using the same, which has the following advantages:

[0032] The device for forming hook and loop fasteners and its usage method include a cutter holder set inside an i-shaped cutting frame, which provides a stable guide for the cutter holder's movement. At the same time, the guide block fits against the upper wall of the cutting frame to form a clamping structure. At this time, the free end of the material tray and the clamping structure complete the tensioning of the material. The retraction groove and the cutting blade are precisely aligned, forming a double guarantee of "frame guidance + groove positioning" to ensure that the cut is flat and vertical, solving the problem of tilted cuts in manual cutting or traditional devices.

[0033] The feeding assembly drives the feeding plate to rise and fall through the first lifting device, and works with the guiding assembly to guide the material. The feeding plate is precisely matched with the first U-shaped groove of the winding roller, and the free end of the material is inserted into the first U-shaped groove to realize the feeding limit of the free end of the material.

[0034] After winding is completed, the unloading assembly drives the support plate to rise through the second lifter. The second U-shaped groove of the support precisely receives the winding roller, and then the second pusher pushes the support to move along the support groove. In conjunction with the first and second transfer devices, the roll material is automatically transferred without the need for manual disassembly and handling, avoiding frequent machine downtime and significantly improving production continuity, thus meeting the needs of large-scale production.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figures 1-9 A device for forming hook and loop fasteners includes a base 1, a center plate 2, a first motor 3, and a take-up roller 4. The center plate 2 is disposed on the base 1. The output end of the first motor 3 passes through the center plate 2 and is connected to the take-up roller 4. A first U-shaped groove is disposed on the front side of the take-up roller 4. The device also includes:

[0047] The guide assembly includes a support frame 5, a drive component, positive and negative toothed rods 6, a first slide plate 7, an upper guide frame 8, and a lower guide frame 9. The support frame 5 is provided on the front side of the center plate 2. The inner wall of the support frame 5 is symmetrically provided with sliding grooves at both ends. The positive and negative toothed rods 6 are rotatably arranged in the sliding grooves. The support frame 5 is also provided with a drive component that drives the two sets of positive and negative toothed rods 6 to rotate on the side near the material input end. The front and rear sides of the first slide plate 7 are threadedly connected to the positive and negative toothed rods 6. The upper guide frame 8 and the lower guide frame 9 are respectively provided on the upper and lower sides of the first slide plate 7.

[0048] The cutting assembly includes a second sliding plate 10, a guide block 11, a cutting frame 12, and a cutter. The front and rear sides of the second sliding plate 10 extend into the slide groove and are threadedly connected to the positive and negative toothed rods 6. A guide block 11 is provided on the upper end of the second sliding plate 10 away from the driving component. A knife relief groove is provided on the guide block 11. A U-shaped cutting frame 12 is also provided on the support frame 5. The upper wall of the cutting frame 12 can contact the guide block 11. A cutter for cutting materials is also provided on the center plate 2.

[0049] The feeding assembly includes a top plate 13, a first lifter 14, a lifting plate 15, and a feeding plate 16. The top plate 13 is provided on the front side of the upper part of the center plate 2. The output end of the first lifter 14 passes through the top plate 13 and is connected to the lifting plate 15. The feeding plate 16, which is adapted to the first U-shaped groove, is provided below the lifting plate 15.

[0050] The base 1 is also provided with a material feeding component.

[0051] In this embodiment, a third lifting device 36 is also provided on the top plate 13. The output end of the third lifting device 36 passes through the top plate 13 and is connected to the pressure plate 37. An auxiliary plate 38 is also provided on the support frame 5. The auxiliary plate 38 is located below the top plate 13. A number of guide grooves adapted to the partition groove are provided on the upper guide frame 8. The top wall of the auxiliary plate 38 is flush with the bottom wall of the guide groove.

[0052] The material is fed by the feeding device. Initially, the first motor 3 drives the take-up roller 4 to rotate, so that the first U-shaped groove is connected from top to bottom. The distance between the first slide plate 7 and the second slide plate 10 is small. The material first passes through the upper guide frame 8 and the guide block 11. The free end of the material is located on the side of the take-up roller 4 away from the material input end under the action of gravity and the toughness of the material itself. According to the requirements, the first motor 3 is a servo motor, which can be used with a reducer and a Roots encoder to ensure precise control of the rotation speed and angle.

[0053] At this time, the guide block 11 is located between the feeding plate 16 and the upper guide frame 8. The upper guide frame 8 provides guidance for the material. The guide block 11 is located below the feeding plate 16. The first lifter 14 is started. The first lifter 14 drives the lifting plate 15 to descend under the support of the top plate 13. The lifting plate 15 and the guide block 11 will not interfere with each other. The feeding plate 16 inserts the free end of the material into the first U-shaped groove. Then the first lifter 14 is reset, completing the feeding of the free end of the material. The first motor 3 is started. The first motor 3 drives the winding roller 4 to rotate, which works with the lower guide frame 9 to complete the winding of the material to form a material tray.

[0054] The drive unit is activated. The drive unit includes a cover 17, a second motor 18, a worm gear 19, and a worm 20. The cover 17 is connected to the side wall of the support frame 5. The worm 20 and two worm gears 19 are arranged inside the cover 17. The worm 20 meshes with the two worm gears 19. The output end of the second motor 18 passes through the center plate 2 and the cover 17 and is connected to the worm 20. The cutter includes a first pusher 21, a blade holder 22, and a cutting blade 23. The output end of the first pusher 21 passes through the center plate 2 and is connected to the blade holder 22. The cutting blade 23 is arranged on the side of the blade holder 22 near the retraction groove. The blade holder 22 is arranged inside the cutting frame 12.

[0055] The second motor 18 drives the worm gear 20 to rotate, which in turn drives two worm wheels 19 to rotate synchronously. The two worm wheels 19 then drive two positive and negative toothed rods 6 to rotate. At this time, the first slide plate 7 and the second slide plate 10 move towards each other until the guide block 11 contacts the cutting frame 12. This, in conjunction with the material tray, achieves tensioning and fixing of the material. The third lifting device 36 drives the pressure plate 37 to move downward. The pressure plate 37 contacts the auxiliary plate 38 to limit the material. At this time, the second slide plate 10 causes the lower guide frame 9 to be misaligned with the material tray, preparing for subsequent material feeding.

[0056] In this embodiment, the unloading assembly includes a second lifter 24, a support plate 25, a first bracket 26, a first transferor 27, a second bracket 28, a second transferor 29, a support member, a second pusher 30, and a push plate 31. The center plate 2 is provided with a hollow hole, and the base 1 is provided with a first bracket 26, which is disposed in the hollow hole. The first bracket 26 is provided with a first transferor 27. The upper and lower ends of the second lifter 24 are respectively connected to the support plate 25 and the base 1. The front side of the base 1 is also provided with a second bracket 28, and the second bracket 28 is provided with a second transferor 29. The support plate 25 is provided with a support member. The output end of the second pusher 30 passes through the center plate 2 and is connected to the push plate 31.

[0057] The support component moves to the support plate 25 via the first transfer device 27 on the first support 26. Both the first transfer device 27 and the second transfer device 29 include a transfer frame, transfer rollers, a motor, and a transfer belt, representing a conventional intermittent transfer structure, which will not be elaborated upon here. The support plate 25 has a through-type support groove, and the support component can slide with the support groove. The second support 28 also has an arc-shaped column 32 near the center plate 2. The output end of the support groove is adapted to the arc-shaped column 32, which is located between the left and right side walls of the support groove. The support plate 25 has material inlets on both the front and rear sides. The support component abuts against the arc-shaped column 32 to complete the feeding of the support component. At this time, the second pusher 30 is in a retracted state, and the second lifter 24 is in a retracted state. The material is wound from a contracted state to an extended state until the bottom wall of the support groove of the support plate 25 is flush with the top wall of the second transfer device 29. The support component includes a support frame 33 and a partition plate 34. The support frame 33 is provided with several sets of partition grooves. The support frame 33 is also provided with partition plates 34 located on the front and rear sides of the partition grooves. The partition plate 34 is provided with a second U-shaped groove. The winding roller 4 is located between the two side walls of the second U-shaped groove. At this time, the bottom wall of the second U-shaped groove of the partition plate 34 is located around the winding roller 4. The material tray is wound into the corresponding partition groove. When cutting, the first pusher 21 is started. The telescopic rod of the first pusher 21 is initially in the retracted state. The output end of the first pusher 21 drives the knife holder 22 to feed. The cutting blade 23 of the knife holder 22 cuts the material tensioned in the retraction groove.

[0058] At this time, the free end of the material tray is in a scattered state. As needed, the first motor 3 can be started. The first motor 3 drives the winding roller 4 to rotate and wind the free end of the material tray into the groove. At this time, there is no need to manually glue the free end of the material tray to the material tray body, so that the material tray can be stably wound up. Moreover, the support component realizes the stable storage and collection of each material tray, which is convenient for subsequent transfer and packaging, and there will be no scattering.

[0059] The second pusher 30 is activated, which drives the push plate 31 to move. The push plate 31 abuts against the support frame 33, causing the support frame 33 with several sets of material trays to move onto the second transfer device 29, thus achieving stable material transfer. Then, the second pusher 30 and the second lifter 24 are reset. The lower rear part of the support plate 25 is also provided with a guide frame 35, which is adapted to the output end of the first transfer device 27 to ensure stable feeding of subsequent empty support components.

[0060] The second motor 18 is started and reversed. The first slide plate 7 and the second slide plate 10 move towards each other. Since the cutting end is located at the end of the guide far from the material input, as the first slide plate 7 and the second slide plate 10 gradually reset, the free end of the material will automatically adhere to the winding roller 4 due to gravity and the stress of the material itself, and return to the initial state of waiting to be loaded. After the loading is completed, the third lifting device 36 resets and waits for the subsequent material tray to be formed.

[0061] In this embodiment, the central plate 2 is also provided with reinforcing ribs 39 that are connected to the left and right side walls of the support frame 5 to ensure the strength of the equipment.

[0062] In this embodiment, the first thruster 21, the second thruster 30, the first lifter 14, the second lifter 24, and the third lifter 36 can all be cylinders;

[0063] In this embodiment, the rotation of the worm gear 19 and worm 20 can also be replaced by two sets of bevel gears cooperating with a rotating shaft for transmission.

[0064] In this embodiment, the guide block 11 and the first sliding plate 7 may have rounded edges in the parts that come into contact with the material to prevent them from scratching the material.

[0065] The present invention further provides a method of using an apparatus for forming hook and loop fasteners, comprising the following steps:

[0066] Step 1: The first motor 3 drives the take-up roller to rotate under the support of the center plate 2, and the upper and lower sides of the first U-shaped groove of the take-up roller are connected.

[0067] Step 2: The cut material first passes through the upper guide frame 8 on the second slide plate 10. At this time, the distance between the first slide plate 7 and the second slide plate 10 is small. The first slide plate 7 and the guide block 11 are located on the right side of the lifting plate 15. Then it passes through the guide block 11, and then the end of the material overlaps on the left side of the take-up roller (after the free end of the material is cut, it will naturally fall on the left side of the take-up roller due to gravity).

[0068] Step 3: Start the first lifting device 14. The first lifting device 14 drives the lifting plate 15 to descend. The free end of the material is folded and limited in the first U-shaped groove. The first lifting device 14 drives the lifting plate 15 to reset.

[0069] Step 4: Start the first motor 3 to complete the material winding. Initially, the second lifter 24 is in the retracted state. Then, start the unloading assembly. The first conveyor drives the support to move to the arc-shaped column 32 and then stops. The second lifter starts the support to rise, and the material is confined within the support.

[0070] Step 5: Start the drive unit. The first slide plate 7 and the second slide plate 10 move in opposite directions until the guide block 11 and the cutting frame 12 clamp the material to be loaded, and the lower guide frame 9 of the second slide plate 10 is misaligned with the wound material.

[0071] Step 6: Start the cutter to cut the tensioned part of the free end of the wound material. During the cutting, the third lifter 36 is activated so that the pressure plate 37 and the auxiliary plate 38 can limit the material of the feeding part, thereby ensuring the stability of the free end of the material. At this time, the material roll is limited by the support member, and the support member is limited by the support plate 25. The first motor 3 is started as needed to continue winding the free end of the material roll. Then the second pusher 30 is started, and the push plate 31 transfers the support member carrying the material roll to the second transferor 29. Then the second transferor 29 transfers the material roll. The cutting component is reset, the driver drives the first slide plate 7 and the second slide plate 10 to reset, and the second lifter 24 is reset. After the material is loaded, the third lifter 36 is reset. Then the above steps are repeated to complete the subsequent material winding and transfer.
