Description

Technical Field

[0001] The present application relates to the field of strapping processing equipment, and particularly relates to a fully automatic forming equipment for the end and loop parts of a strap. Background Art

[0002] Currently, in the production and processing of straps, the forming of the end and loop parts usually requires multiple processes such as cutting, winding and folding, and stitching. Traditional processes mostly rely on manual operation, with low efficiency and difficult to guarantee accuracy. Especially when dealing with the loop parts of high-strength materials, problems such as unstable structure and insecure stitching are likely to occur.

[0003] Currently, in the automatic forming equipment for the end and loop parts of a strap, the existing technology (such as the automatic sewing machine system disclosed in CN110485069B) mainly focuses on the combined assembly and stitching of multiple components such as webbing, hooks, and fabric labels. It realizes partial automation by integrating processes such as webbing feeding, cutting, bending, fabric label and hook assembly, and handling and stitching. However, this technology has the following limitations:

[0004] (1) The existing equipment needs to simultaneously process the collaborative assembly of multiple components such as webbing, hooks, and fabric labels, resulting in a complex mechanical structure (such as setting up a hook feeding device, a fabric label feeding device, etc.), and the workpiece needs to be transferred multiple times through a handling mechanism, with a long process connection time. For example, for the forming of its loop part, the right end of the webbing needs to be bent to cover the fabric label first, then the left end is bent around the hook to close the loop, and finally stitched in two times, significantly increasing the production beat.

[0005] (2) In the existing technology, the formation of the strap loop part relies on the hook as a support, and the folding is realized by the segmented pushing of a mechanical stop column and a top block. This method is only applicable to specific forms (such as a hook-closed loop), and there is insufficient control over the tension of the strap itself, making it difficult to form a tight and symmetrical ring structure alone. For the forming requirement of a pure strap loop part without a hook, the existing equipment cannot be directly adapted.

[0006] (3) Due to the need to be compatible with the assembly of multiple components, the design of the bending path, clamping structure, etc. of the existing equipment highly depends on the positioning of the hook and the fabric label. For straps of different widths or materials, the mold needs to be replaced or the parameters need to be adjusted, resulting in low flexibility of the equipment. For example, its right bending device needs to match the position of the fabric label, and the left bending device needs to align with the hook-closed loop, and it is impossible to independently optimize the forming process of the strap loop part.

[0007] (4) In the existing technology, the stitching of the loop part and the strap body needs to ensure the position consistency of the hook, fabric label, and webbing at the same time. If there is any displacement in any link (such as the installation deviation of the hook, inaccurate adsorption of the fabric label), it will cause the stitching position to shift. While the forming of a pure strap loop part only needs to control the winding accuracy of the strap itself, without the need for multi-component collaboration, and theoretically higher positioning accuracy can be achieved. Summary of the Invention

[0008] The object of the present application is to propose a fully automatic device focusing on the forming of the loop part of the strap. Through the coordinated control of the rotary driving device and the clamping part, the predetermined length section of the strap is directly wound and folded to form an independent annular structure.

[0009] To achieve the above object, the present application proposes the following technical solutions:

[0010] A fully automatic device for forming the end loop part of a strap, comprising a strap feeding mechanism, a strap cutting mechanism, a strap end winding and folding mechanism, a second strap pulling mechanism, a strap sewing mechanism and a strap discharging mechanism; the strap feeding mechanism is used to convey the wound strap to the strap end winding and folding mechanism; the strap end winding and folding mechanism is arranged on one side of the strap feeding mechanism, and the strap end winding and folding mechanism includes a clamping part and a rotary driving device, the clamping part is installed on the rotary driving device, the clamping part is used to clamp the predetermined length section of the strap, and the rotary driving device drives the clamping part to rotate, so that the end of the predetermined length section of the strap is folded over the strap body to form an annular structure; the strap cutting mechanism is arranged between the strap feeding mechanism and the strap end winding and folding mechanism, and is used to cut the strap after the strap body is folded to form an annular structure; after the strap is cut, the second strap pulling mechanism clamps the annular structure of the strap and conveys it to the working area of the strap sewing mechanism; the strap sewing mechanism is used to sew the connection between the annular structure and the strap body; the strap discharging mechanism discharges the sewn strap.

[0011] Further, the clamping part includes a first clamping driving device and a first clamping plate part, and the first clamping plate parts are respectively arranged up and down opposite to each other on the first clamping driving device, and the first clamping driving device is used to drive the first clamping plate part to perform a clamping movement.

[0012] Further, the first clamping plate part includes a first left clamping plate and a first right clamping plate, and there is a first avoiding part between the first left clamping plate and the first right clamping plate, and the first avoiding part is used to avoid the clamping area of the second strap pulling mechanism, and the position of the first avoiding part corresponds to the annular structure, so as to ensure that the second strap pulling mechanism can clamp the annular structure and transfer it to the working area of the sewing machine.

[0013] Further, the strap end winding and folding mechanism further includes an auxiliary strap winding device, which includes a clamping roller and a clamping plate. The clamping roller is rotatably arranged on one side of the clamping part, and its axis is perpendicular to the strap conveying direction. The clamping plate is arranged opposite to the clamping roller, and forms an adjustable clamping gap with the clamping roller through a second clamping driving device. When the clamping part rotates and folds the strap, the clamping roller and the clamping plate cooperate to clamp the non-wound section of the strap, and restrain the swinging of the strap through friction to ensure that the tail end of the strap with a predetermined length is stably wound into a loop.

[0014] Further, the clamping plate is provided with a second avoidance part, which is a rectangular notch opened on the right side of the clamping plate. The clamping jaw of the second strap pulling mechanism extends into the clamping plate through the second avoidance part to clamp the non-wound section of the strap.

[0015] Further, the strap end winding and folding mechanism further includes a second Y-axis driving module. The strap end winding and folding mechanism is installed on the second Y-axis driving module, and the second Y-axis driving module is used to drive the strap end winding and folding mechanism to move along the Y-axis direction.

[0016] Further, the strap feeding mechanism includes a turntable tape feeding device, a pressing roller device, a guiding device and a first strap pulling device. The turntable tape feeding device includes a rotatable tape feeding turntable for installing the strap coil. The pressing roller device includes at least a pair of cooperating pressing rollers, and the strap is stably conveyed forward through the friction between the pressing rollers. The guiding device includes a plurality of guiding rods arranged on the strap conveying path, and guiding plates are arranged on the guiding rods, and the guiding plates are used to guide the strap to be conveyed along a predetermined path to prevent the strap from running off. The first strap pulling device includes a clamping jaw and a clamping jaw driving mechanism for driving the clamping jaw to move. The clamping jaw of the first strap pulling device is used to clamp the end of the strap, and the clamping jaw driving mechanism drives the clamping jaw to move along the strap conveying direction.

[0017] Further, a turntable limiting device is arranged on one side of the tape feeding turntable.

The first fixing sleeve is fixed on the rotating shaft and is used to limit the sliding stroke of the first limiting block. The turntable limiting device drives the first limiting block to press one side of the tape feeding turntable through the elastic force of the first limiting spring, so that the tape feeding turntable cooperates with the tape feeding turntable on the other side to clamp the strap coil and prevent the strap from loosening or shifting during the tape feeding process.

[0018] Further, the pressing roller device further includes an adaptive pressing device, which includes a first pressing spring, a first mounting seat, a first pressing adjustment screw, and a first pressing push plate. The first mounting seat is used to mount the end of the pressing roller. The first pressing spring is arranged between the first mounting seat and the first pressing push plate.

[0019] Further, a spacing adjustment device is provided on one side of the guiding plate, and the spacing adjustment device is used to adjust the spacing between the two guiding plates.

[0020] The beneficial effects of this application are as follows:

[0021] (1) Compared with the prior art, this application omits the assembly processes of external components such as hooks and cloth labels, and only needs to complete the cutting, winding, and sewing of the binding strap itself, reducing the complex operations of multi-station collaboration. Through the coordinated action of the rotary driving device and the clamping part, the forming of the annular structure can be completed in a single winding process, and the production beat is shortened by more than 50%, significantly improving the production efficiency.

[0022] (2) This application uses a rotary driving device to precisely control the winding angle, combined with the dynamic adjustment of the binding strap tension by the clamping part, to ensure the symmetry and tightness of the annular structure.

[0023] (3) By adjusting the rotation speed, rotation angle of the rotary driving device and the pressure parameters of the clamping part, this application can quickly adapt to the forming requirements of binding strap loop parts with different widths, thicknesses, and materials, without replacing the mold or mechanical structure, significantly improving the flexibility level of the production line.

[0024] (4) This application directly clamps the annular structure through the second pulling strap mechanism to ensure the stable position of the connection between the annular structure and the binding strap main body. Combined with the high-precision positioning system of the sewing machine mechanism, it ensures the appearance consistency and structural strength of the product. Description of the Drawings

[0059] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present application and are not configured to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0060] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, the elements defined by the statement "including..." do not exclude the existence of additional identical elements in the process, method, article or device including the elements.

[0061] It should be understood that when describing the structure of a component, when a layer or a region is referred to as being "above" or "over" another layer or another region, it may mean directly above the other layer or another region, or there may be other layers or regions between it and the other layer or another region. And if the component is turned over, this layer or region will be "below" or "beneath" the other layer or region.

[0062] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0063] As Figure 1 shown, the end of the strap A is turned over to form an annular structure A1, and finally the connection A2 between the annular structure A1 and the strap body A4 is sutured.

[0064] As Figure 2As shown in the figure, a fully automatic forming device for the end ring part of a binding band includes a binding band feeding mechanism 100, a binding band cutting mechanism 200, a binding band end winding and folding mechanism 300, a second strap pulling mechanism 400, a binding band sewing machine mechanism 500, and a binding band discharging mechanism 600; the binding band feeding mechanism 100 is used to convey the wound binding band to the binding band end winding and folding mechanism 300; the binding band end winding and folding mechanism 300 is arranged on one side of the binding band feeding mechanism 100, as Figure 3 shown, the binding band end winding and folding mechanism 300 includes a clamping part 310 and a rotary driving device 320. The clamping part 310 is installed on the rotary driving device 320. The clamping part 310 is used to clamp a predetermined length section of the binding band A. The rotary driving device 320 drives the clamping part 310 to rotate, so that the end of the binding band of the predetermined length section is folded over the binding band body to form an annular structure A1; the binding band cutting mechanism 200 is arranged between the binding band feeding mechanism 100 and the binding band end winding and folding mechanism 300. After the binding band body is folded to form the annular structure A1, it is used to cut the binding band; after the binding band is cut, the second strap pulling mechanism 400 clamps the annular structure A1 of the binding band and conveys it to the working area of the binding band sewing machine mechanism 500; the binding band sewing machine mechanism 500 is used to sew the connection A2 between the annular structure and the binding band body; the binding band discharging mechanism 600 discharges the sewn binding band.

[0065] As Figure 3 shown, in one embodiment, the clamping part 310 includes a first clamping driving device 311 and a first clamping plate part. The first clamping plate parts are respectively arranged up and down opposite to each other on the first clamping driving device 311. The first clamping driving device 311 is used to drive the first clamping plate part to perform a clamping motion. The first clamping driving device is a cylinder.

[0066] As Figure 3 and Figure 5 shown, in one embodiment, the first clamping plate part includes a first left clamping plate 312 and a first right clamping plate 313. There is a first avoiding part 314 between the first left clamping plate 312 and the first right clamping plate 313. The first avoiding part 314 is used to avoid the clamping area of the second strap pulling mechanism 400. The position of the first avoiding part 314 corresponding to the annular structure ensures that the second strap pulling mechanism 400 can clamp the annular structure and transfer it to the working area of the sewing machine.

[0067] As Figure 3 and Figure 4As shown, in one embodiment, the strap end winding and folding mechanism 300 further includes an auxiliary strap winding device 700. The auxiliary strap winding device 700 includes a second clamping drive device 740, a clamping roller 710, and a clamping plate 720. The clamping roller 710 is rotatably provided on one side of the clamping portion 310, and its axis is perpendicular to the strap conveying direction. The clamping plate 720 is disposed opposite to the clamping roller 710, and an adjustable clamping gap is formed with the clamping roller 710 through the second clamping drive device 740. When the clamping portion 310 rotates and folds the strap, the clamping roller 710 and the clamping plate 720 cooperate to clamp the non-winding section A3 of the strap, and the swing of the strap is restricted by friction to ensure that the tail end of the strap of a predetermined length is stably wound into a loop. By the friction between the clamping roller 710 and the clamping plate 720, the free end of the non-winding section A3 of the strap is restricted, effectively suppressing the swing caused by centrifugal force or material elasticity during rotational winding, ensuring that the tail end is tightly wound into a loop along a predetermined path, and avoiding the loosening or deformation of the annular structure.

[0068] As Figure 5 shown, in one embodiment, the clamping plate 720 is provided with a second avoidance portion 730. The second avoidance portion 730 is a rectangular notch opened on the right side of the clamping plate 720. The jaws of the second strap pulling mechanism 400 extend into the clamping plate 720 through the second avoidance portion 730 to clamp the non-winding section of the strap.

[0069] As Figure 4 shown, in one embodiment, the strap end winding and folding mechanism 300 is installed on the second Y-axis drive module 330, and the second Y-axis drive module 330 is used to drive the strap end winding and folding mechanism 300 to move along the second Y-axis direction.

[0070] As Figure 6 shown, in one embodiment, the strap feeding mechanism 100 includes a turntable tape feeding device 110, a pressing roller device 120, a guiding device 130, and a first strap pulling device 140. The turntable tape feeding device 110 includes a rotatable tape feeding turntable 111 for installing the strap reel. The pressing roller device 120 includes at least a pair of cooperating pressing rollers 121, and the strap is stably conveyed forward by the friction between the pressing rollers 121. The guiding device 130 includes a plurality of guiding rods 131. The guiding rods 131 are arranged on the strap conveying path, and guiding plates 132 are provided on the guiding rods 131. The guiding plates 132 are used to guide the strap to be conveyed along a predetermined path to prevent the strap from running off. As Figure 10 shown, the first strap pulling device 140 includes a jaw 141 and a jaw drive mechanism 142 for driving the movement of the jaw. The jaw of the first strap pulling device 140 is used to clamp the end of the strap, and the jaw drive mechanism 142 drives the jaw to move along the strap conveying direction.

[0071] As Figure 7As shown, in one embodiment, a turntable limiting device 150 is provided on one side of the tape feeding turntable 111. The turntable limiting device 150 includes a first limiting block 151, a first limiting spring 152, and a first fixing sleeve 153. The first limiting block 151 is slidably sleeved on the rotating shaft of the tape feeding turntable 111; the first limiting spring 152 is sleeved on the rotating shaft and is located between the first limiting block 151 and the tape feeding turntable 111, and is used to apply an axial elastic force to the first limiting block 151. The first fixing sleeve 153 is fixed on the rotating shaft and is used to limit the sliding stroke of the first limiting block 151; the turntable limiting device 150 drives the first limiting block 151 to press against one side of the tape feeding turntable 111 through the elastic force of the first limiting spring 152, so that the tape feeding turntable 111 cooperates with the tape feeding turntable 111 on the other side to clamp the binding tape roll material, preventing the binding tape from loosening or shifting during the tape feeding process.

[0072] As Figure 8 shown, in one embodiment, the pressing roller device 120 further includes an adaptive pressing device 160. The adaptive pressing device 160 includes a first pressing spring 161, a first mounting seat 162, a first pressing adjustment screw 163, and a first pressing push plate 164. The first mounting seat 162 is used to mount the end of the pressing roller 121. The first pressing spring 161 is arranged between the first mounting seat 162 and the first pressing push plate 164. The first pressing adjustment screw 163 is connected to the first pressing push plate 164. The first pressing adjustment screw 163 is mounted on the side plate. The first pressing adjustment screw 163 is used to drive the first pressing push plate 164 to move up and down to adjust the compression amount of the first pressing spring 161, thereby adaptively adjusting the pressing force of the pressing roller on the binding tape.

[0073] As Figure 9 shown, in one embodiment, a spacing adjustment device is provided on one side of the guide plate 132. The spacing adjustment device is used to adjust the spacing between the two guide plates 132.

[0074] As Figure 9 shown, in one embodiment, the spacing adjustment device includes a spacing adjustment screw 133. The spacing adjustment screw 133 is horizontally arranged perpendicular to the binding tape conveying direction, and the surface of the screw is provided with a positive and negative thread section; a threaded hole is provided on one side of the guide plate 132, and the threaded hole directly cooperates with the positive and negative thread sections of the spacing adjustment screw 133; when the spacing adjustment screw 133 rotates, the guide plate 132 moves along the axis of the screw through the threaded hole, thereby adjusting the spacing between the two guide plates 132.

[0075] As Figure 10 shown, in one embodiment, clamping teeth 143 are provided on the clamping jaw 141, and the clamping teeth 143 are conical. Through the tip contact design, the conical clamping teeth 143 can generate a higher local pressure under the same clamping pressure, significantly improving the friction force with the surface of the binding tape.

[0076] As Figure 11 shown, in one embodiment, the strap cutting mechanism 200 includes an upper cutter 210, a lower cutter 220, a cutter driving device 230, a cutter mounting seat 240, a cutter lifting guide rod 250, and a cutter buffer spring 260. The upper cutter 210 is located above the lower cutter 220. The cutter driving device 230 is connected to the upper cutter 210 and drives the upper cutter 210 to reciprocate in the vertical direction. The cutter lifting guide rod 250 is vertically arranged between the upper cutter 210 and the cutter mounting seat 240. The upper cutter 210 is slidably connected to the cutter lifting guide rod 250. The cutter buffer spring 260 is sleeved on the cutter lifting guide rod 250 and is located between the upper cutter 210 and the cutter mounting seat 240. When the cutter driving device 230 drives the upper cutter 210 to press down, the cutter buffer spring 260 absorbs the impact energy through elastic deformation, and the cutter lifting guide rod 250 ensures that the upper cutter 210 and the lower cutter 220 come into parallel contact, realizing the smooth cutting of the strap.

[0077] As Figure 11 shown, in one embodiment, the strap cutting mechanism 200 further includes a blowing device 270. The blowing device 270 is arranged on one side of the strap cutting mechanism 200, and the blowing direction of the blowing device 270 is the moving direction of the strap. The blowing device 270 blows along the moving direction of the strap to timely remove the debris (such as plastic chips, fibers, etc.) generated during the cutting process, avoid the accumulation of debris in the cutting mechanism or subsequent workstations, and prevent equipment failures or product contamination caused by debris blockage. The blowing device 270 is a fan.

[0078] In addition, the wind force pushes the cut strap loop part to move along the conveying direction, reducing the stagnation caused by gravity or friction, ensuring that the second strap pulling mechanism 400 can quickly clamp and transfer it to the sewing station, and shortening the production cycle.

[0079] As Figure 12 shown, in one embodiment, a first X-axis driving module 800 is arranged below the second strap pulling mechanism 400 and the strap feeding mechanism 600. The first X-axis driving module 800 synchronously drives the second strap pulling mechanism 400 and the strap feeding mechanism 600 to move along the moving direction of the strap.

[0080] As Figure 13As shown, in one embodiment, the second strap mechanism 400 includes a strap clamping assembly 410 and a first Y-axis driving module 420. The first Y-axis driving module 420 drives the strap clamping assembly 410 to move in a direction perpendicular to the movement of the strap. The strap clamping assembly 410 includes a movable clamping plate 411, a fixed clamping plate 412, and a movable clamping plate lifting driving device 413. The movable clamping plate 411 and the fixed clamping plate 412 are arranged opposite to each other vertically. The movable clamping plate lifting driving device 413 drives the movable clamping plate to approach or move away from the fixed clamping plate 412. Third avoidance portions 414 are provided on both the movable clamping plate and the fixed clamping plate 412.

[0081] As Figure 14 As shown, in one embodiment, the strap feeding mechanism 600 includes a feeding head 610, a feeding head lifting driving device 620, and a second Y-axis transverse movement module 630. The feeding head 610 is installed on the feeding head lifting driving device 620, and the feeding head lifting driving device 620 is installed on the second Y-axis transverse movement module 630. The second Y-axis transverse movement module 630 drives the feeding head to move in a direction perpendicular to the movement of the strap, and the feeding head lifting driving device 620 drives the feeding head to perform a lifting movement.

[0082] In one embodiment, suction holes 640 are provided at the bottom of the feeding head, and a suction force adjusting gear 650 is provided inside the feeding head. The purpose of providing the suction holes 640 in this embodiment is that the surface of the strap has a printed logo. Mechanical clamping or pushing is likely to cause surface scratches or indentations, while the suction method reduces the risk of damage to the surface through uniformly distributed negative pressure contact.

[0083] The suction holes 640 are usually small holes uniformly distributed at the bottom of the feeding head. Their diameter and spacing will be designed according to actual requirements. Generally, the diameter is relatively small to ensure that sufficient suction force can be generated. The shape of the suction holes 640 can be circular, square, etc., and the common one is circular, so that the suction force distribution can be more uniform. The suction holes 640 are connected to the air path inside the feeding head. The air path can be a separate channel or an interconnected cavity for transmitting the suction force to the suction holes 640.

[0084] The suction adjustment gear 650 is usually installed inside the blanking head and connected to the valve or adjustment device in the air circuit. Its working principle is as follows: The suction adjustment gear 650 cooperates with the rack or gear mechanism on the valve. When the gear rotates, it drives the opening degree of the valve to change. The size of the valve opening directly affects the gas flow in the air circuit, thereby adjusting the suction force at the adsorption hole 640. For example, when a larger suction force is required to adsorb heavier or smoother-surfaced straps, rotate the suction adjustment gear 650 to increase the valve opening, the gas flow in the air circuit increases, and the suction force at the adsorption hole 640 also increases accordingly. Conversely, when adsorbing lighter straps or straps with lower suction requirements, rotate the suction adjustment gear 650 to reduce the valve opening and lower the suction force at the adsorption hole 640.

[0085] In one embodiment, the strap sewing machine mechanism 500 includes a sewing machine device 510 and an auxiliary feeding device 520. The auxiliary feeding device 520 is arranged below the sewing machine device 510. The auxiliary feeding device 520 is used to clamp and move the annular structure at the end of the strap, facilitating the sewing machine device 510 to sew the connection between the annular structure and the strap body.

[0086] As Figure 17 shown, in one embodiment, the auxiliary feeding device 520 includes an upper auxiliary clamping plate 521, a lower auxiliary clamping plate 522, a third lifting drive device 523, and an auxiliary clamping plate XY-axis transverse movement module 524. The upper auxiliary clamping plate 521 and the lower auxiliary clamping plate 522 are arranged downward opposite to each other. The upper auxiliary clamping plate 521 is movably installed on the third lifting drive device 523, and the lower auxiliary clamping plate 522 is fixedly installed on the third lifting drive device 523. The third lifting drive device 523 drives the upper auxiliary clamping plate 521 to approach or move away from the lower auxiliary clamping plate 522. The third lifting drive device 523 is installed on the auxiliary clamping plate XY-axis transverse movement module 524, and the auxiliary clamping plate XY-axis transverse movement module 524 drives the upper auxiliary clamping plate 521 and the lower auxiliary clamping plate 522 to clamp the strap and move along the X-axis and Y-axis directions.

[0087] As Figure 17 shown, in one embodiment, a fourth avoidance portion 525 is provided on the upper auxiliary clamping plate 521. The fourth avoidance portion 525 is used for the sewing machine device 510 to perform sewing work.

[0088] This application realizes the efficient forming of the annular part at the end of the strap through the full-process automatic integration and rotary winding technology. The specific working process is as follows:

[0089] 1. Feeding stage: The turntable tape releasing device 110 releases the roll-shaped strap A. The pressing roller device 120 stably conveys it with an adaptive pressing force. The adjustable-spacing guiding plate 132 of the guiding device 130 ensures that the strap A feeds linearly along a predetermined path. The jaws of the first tape pulling device 140 clamp the end of the strap A and drive it to move towards the winding and folding mechanism.

[0090] 2. Winding and folding stage: The clamping part 310 clamps a predetermined length section of the strap A, and the rotary driving device 320 drives the clamping part 310 to rotate 180°, causing the end of the strap to fold around the main body to form an annular structure A1. The clamping roller 710 of the auxiliary winding device cooperates with the clamping plate 720 to restrain the swing of the non-winding section A3 through friction, ensuring the tight formation of the ring part.

[0091] 3. Cutting stage: The upper cutter 210 of the strap cutting mechanism 200 is smoothly pressed down under the action of the buffer spring, and cooperates with the lower cutter 220 to cut the strap. The blowing device 270 removes the chips on the cutter and assists in conveying.

[0092] 4. Transferring and sewing stage: The jaws of the second pulling belt mechanism 400 clamp the annular structure A1 through the avoidance part, and are transferred to the sewing machine mechanism by the X / Y axis driving module. The upper / lower auxiliary clamping plates 522 of the auxiliary feeding device 520 clamp the ring part, and are accurately positioned to the sewing machine working area through the XY axis transverse movement module to realize the sewing of the connection part A2 between the ring part and the main body.

[0093] 5. Unloading stage: The unloading head of the unloading mechanism adsorbs the finished product through the adsorption holes 640, and is transferred to the designated position by the second Y axis transverse movement module to complete automatic unloading.
