Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to a zipper bonding processing equipment, system, processing method and processing technology, preferably applied to the rapid bonding processing of the edge of a flexible material (such as an airship bladder) piece to a zipper. Background Technology

[0002] In the manufacturing process of airship capsules, the welding of the capsule segments is crucial. Currently, the widely used methods for processing capsule welds rely on operators and equipment to position, hot-press, and cool the edges of the capsule segments for shaping, using intermittent heat sealing equipment or continuous welding equipment.

[0003] However, this method of processing the airship body weld has the problems of low efficiency and insufficient accuracy in manually positioning the airship body weld. To solve these problems, the applicant, after a long period of research and practice, has proposed a high-efficiency welding process for airship bodies. This process mainly includes two pre- and post-processing steps: zipper bonding and positioning processing, and welding processing of adjacent airship body pieces after zipper bonding. First, a single-sided zipper is reliably installed and bonded to the edge of the airship body piece; then, in the subsequent process, welding equipment is used to weld the two adjacent zipper-bonded pieces in the heat-sealing zone on the other side of the airship body piece where the zipper is not bonded, forming a reliable weld. This process has the advantages of quick and high-precision positioning of the piece weld and high welding efficiency.

[0004] However, existing technologies lack specialized equipment and techniques for quickly bonding zippers to the edges of pouch body panels. Furthermore, similar problems exist in other fields where zippers are bonded to panels, including low bonding accuracy, low efficiency, and difficulty in guaranteeing bonding quality.

[0005] To achieve the above objectives, those skilled in the art urgently need to develop a zipper bonding processing device that can quickly, accurately, and reliably bond a single-sided zipper to the edge of the bag body piece. Summary of the Invention

[0006] The purpose of this invention is to provide a zipper and cut piece edge alignment and bonding processing equipment and method. By setting the right side of the drive wheel, the right side of the pressure wheel, the inner side wall of the limiting groove, and the right side wall of the limiting structure to be coplanar, the technical problems of difficulty in aligning the zipper with the edge of the bag body or other cut pieces and unreliable bonding are solved, so as to achieve fast, accurate and reliable bonding of the zipper and the cut piece, and improve processing efficiency and quality.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: On one hand, a zipper bonding processing device is provided. This processing device includes a frame and a positioning component, a pressure component, and a drive wheel mounted on the frame. The positioning component includes a guide wheel and a guide limiter mounted on the frame. The guide wheel has a limiting structure adapted to match the zipper width, and the guide limiter has a limiting groove for limiting the movement path of the cut piece. The edge of the cut piece abuts against the inner wall of the limiting groove, and the zipper tooth edge abuts against the right side wall of the limiting structure. The pressure component includes a pressure device, a pressure rod, and a pressure roller. The pressure device drives the pressure rod to move the pressure roller vertically. The drive wheel cooperates with the pressure roller to drive the zipper and the cut piece to move synchronously. The right side of the drive wheel, the right side of the pressure roller, the inner wall of the limiting groove, and the right side wall of the limiting structure are coplanarly arranged on the same vertical plane, realizing the alignment of the zipper tooth edge with the edge of the cut piece.

[0008] Furthermore, the limiting structure is an annular groove formed on the guide wheel and adapted to the width of the zipper; the guide limiter is a limiting block fixedly connected to the frame, and the limiting groove formed on the limiting block is a C-shaped limiting groove.

[0009] Furthermore, the pressure device is located at one end of the pressure rod, and the pressure roller is located at the other end of the pressure rod. Under the action of the pressure device, the pressure rod drives the pressure roller to move vertically up and down.

[0010] Furthermore, the pressure assembly also includes two guide blocks for limiting the movement path of the pressure rod, which are respectively disposed near both ends of the pressure rod and fixedly connected to the frame.

[0011] Furthermore, the pressure device includes a rotary handle. When the rotary handle is rotated upward, the pressure rod drives the pressure roller to move vertically upward. When the rotary handle is rotated downward, the pressure rod drives the pressure roller to press vertically downward.

[0012] Furthermore, an annular receiving groove is provided on the right side of the pressure roller for the zipper teeth to pass through.

[0013] Furthermore, the processing equipment also includes a peeling wheel assembly for cold bonding and / or a welding heating mechanism for hot bonding, wherein the peeling wheel assembly includes a driving wheel and a driven wheel for synchronously removing the zipper protective film.

[0014] The welding heating mechanism includes a multi-degree-of-freedom articulated arm and a heating block at its end. The upper and lower surfaces of the head of the heating block are concave arc structures, and the curvature of the arc structure is the same as that of the pressure roller and the drive roller.

[0015] Furthermore, a temperature sensor is provided on the side of the heating block.

[0016] Furthermore, the processing equipment also includes a chain reel, located at the back of the frame, for storing zippers, which is freely rotatable and has a damping function.

[0017] Furthermore, the guide wheel includes a first guide wheel near the chain and a second guide wheel near the pressure wheel.

[0018] Furthermore, the guide limiter C-shaped limiting groove is used to limit the movement path of the cut piece. Its structure is a C-shaped channel structure composed of upper and lower baffles and a single inner side wall. It is made of rigid material and can resist the deformation caused by the weight of the capsule cut piece. Optionally, the C-shaped limiting groove of the guide limiter described in this invention can also be a C-shaped rod structure or a C-shaped spring clip structure formed by connecting upper and lower cantilever rods, which can achieve the same purpose of limiting the movement path of the cut piece.

[0019] This application also provides a zipper bonding processing method, which is implemented using the aforementioned zipper bonding processing equipment, and includes: The edge of the cut piece is positioned by the limiting groove, so that the edge of the cut piece is aligned with the right side of the drive wheel; The guide wheel's limiting structure positions the zipper teeth, aligning them with the right side of the drive wheel. The pressure roller is driven to press down, pressing the cut piece and zipper tightly between the drive roller and the pressure roller; The drive wheel rotates, synchronously conveying the cut pieces and zippers to achieve edge bonding.

[0020] Furthermore, the zipper bonding process specifically includes the following steps: Step S1: Prepare the cut pieces and zipper. Wrap the zipper around the chain wheel so that the zipper teeth are on the right side of the chain wheel and the heat-sealed or adhesive side is facing outwards. Step S2: Pass the cut piece through the C-shaped limiting groove of the guide limiter, and abut the edge of the cut piece against the inner side wall of the C-shaped limiting groove, with the edge of the cut piece aligned with the right side of the drive wheel; Step S3: Pull the zipper out of the chain tray and let it pass through the annular groove of the guide wheel, aligning the zipper teeth with the right side of the drive wheel. Step S4: If it is heat bonding, adjust the heating block between the zipper and the cut piece by rotating the multi-degree-of-freedom articulated arm, so that the upper surface of the head of the heating block is close to the adhesive surface of the zipper and the lower surface is close to the cut piece. If it is a cold bonding process, peel off the protective film on the adhesive side of the zipper, and pass the protective film through the drive wheel and driven wheel of the peeling wheel assembly to remove the zipper protective film simultaneously. Step S5: Rotate the handle of the pressure device to make the pressure rod drive the pressure roller to move down, pressing the cut piece, zipper and drive wheel together; Step S6: Start the drive wheel to rotate clockwise to achieve welding and feeding. The zipper is automatically fed by the chain disc, and the cut piece is fed through the C-shaped limiting groove. During the feeding process, the edge of the cut piece is tightly attached to the inner wall of the C-shaped limiting groove.

[0021] Furthermore, during the heat bonding process, the temperature sensor monitors the temperature of the heating block in real time and feeds it back to the temperature controller to ensure that the heating block operates under a constant temperature.

[0022] Furthermore, the drive wheel rotates counterclockwise for unloading material.

[0023] Furthermore, during the cold bonding process, the rotational speeds of the drive and driven wheels of the stripping wheel assembly are matched with the rotational speeds of the drive wheel and sprocket.

[0024] This application also provides a zipper bonding processing system, which includes the above-mentioned zipper bonding processing equipment and a control system, wherein the control system is configured to adjust the rotational speed of the drive wheel and / or the heating temperature.

[0025] Furthermore, during cold bonding, the control system is used to adjust the rotational speed of the drive wheel, the sprocket speed, and the stripping wheel speed; During heat bonding, the control system is used to adjust the rotational speed of the drive wheel, the rotational speed of the chain, and the heating temperature of the heating block.

[0026] This application also provides a zipper bonding process, which includes the above-mentioned zipper bonding method, and further includes: Before the zipper bonding process, the frame is fixed to the worktable with a clamp and the working parameters are set. The working parameters include, but are not limited to, the heating temperature of the heating block, the speed of the drive wheel, the speed of the chain, and the speed of the peeling wheel. If it is hot bonding, the heating temperature of the heating block, the speed of the drive wheel, and the speed of the chain are set. If it is cold bonding, only the speed of the drive wheel, the speed of the chain, and the speed of the peeling wheel are set.

[0027] Compared with the prior art, the advantages of the technical solution of this application are as follows: The zipper bonding processing equipment, system, processing method, and processing technology provided in this application solve the technical problems of difficult alignment and unreliable bonding between zippers and the edges of bag body pieces or other pieces by forming a coplanar positioning structure with the right side face of the drive wheel, the right side face of the pressure wheel, the inner side wall of the limiting groove, and the right side wall of the limiting structure. This achieves fast, accurate, and reliable bonding between zippers and pieces, improving processing efficiency and quality.

[0028] Specifically, this application provides a zipper bonding processing device, mainly used to quickly, accurately, and reliably bond a single-sided zipper to the edge of a pouch piece, forming a pouch piece with a zipper on the edge and normal zipping function. The processing device includes a frame, a positioning component, a pressure component, and a drive wheel. The positioning component includes a guide wheel for guiding and limiting the zipper and a limiting groove on the guide wheel for limiting the movement path of the pouch piece. Through the coordinated action of the guide wheel and the guide wheel, precise alignment between the zipper and the pouch piece is achieved. Under the action of the pressure component, the pressure rod drives the pressure wheel to move vertically up and down. Through the matching and pressing working surfaces of the drive wheel and the pressure wheel, the zipper and the pouch piece move synchronously. Furthermore, by setting the right side of the drive wheel, the right side of the pressure wheel, the inner wall of the limiting groove, and the right side of the guide wheel's annular groove coplanar on the same vertical plane, the zipper and the pouch piece work together to align the zipper teeth with the edge of the pouch piece during the bonding movement.

[0029] Furthermore, by using a peeling wheel assembly consisting of a drive wheel and a driven wheel, which is fixedly installed on the left side of the frame, the protective film can be automatically removed while the zipper is being attached and moved. This removal method greatly reduces the exposure time of the zipper adhesive surface to the air, preventing a large amount of dust and other particles in the air from adsorbing onto the adhesive surface and reducing the bonding strength.

[0030] This application combines processing equipment and methods to achieve rapid, accurate, and reliable bonding of zippers and cut pieces. By using both hot and cold bonding methods, it meets the processing needs of different types of zippers, greatly improving processing efficiency and reducing the intensity of manual labor.

[0037] Example 1 Please see Figure 1 , Figure 2As shown, this embodiment provides a zipper bonding processing device, which includes a frame 1 and a positioning component 2, a pressure component 3, and a drive wheel 4 disposed on the frame 1. The positioning component 2 includes a guide wheel 21 and a guide limiter 22 disposed on the frame 1. The guide wheel 21 is provided with a limiting structure matching the width of the zipper. The limiting structure is an annular groove formed on the guide wheel 21. The guide limiter 22 is provided with a limiting groove for limiting the movement path of the pouch piece 9. The limiting groove is preferably a C-shaped limiting groove 220. The edge of the pouch piece 9 abuts against the inner sidewall 221 of the C-shaped limiting groove, and the zipper teeth abut against the right sidewall of the annular groove. The pressure component 3 includes a pressure device. 31. Pressure rod 32 and pressure roller 33: The pressure rod 31 and pressure roller 33 are respectively located at both ends of the pressure rod 32. That is, the pressure rod 31 is located at the top of the frame 1 and acts on one end of the pressure rod 32, and the pressure roller 33 is located at the other end of the pressure rod 32. Under the action of the pressure rod 31, the pressure rod 32 drives the pressure roller 33 to move vertically. The working surfaces of the drive wheel 4 and the pressure roller 33 jointly drive the zipper and the cut piece to move synchronously. The right side surface of the drive wheel 4, the right side surface of the pressure roller 33, the inner side wall 221 of the C-shaped limiting groove, and the right side wall of the annular groove of the guide wheel 21 are coplanarly arranged on the same vertical plane to form a coplanar positioning structure, so as to align the zipper teeth with the edge of the cut piece.

[0038] It should be noted that the "coplanar setting" in this embodiment can be achieved through laser calibration, mechanical blocks or visual positioning; the limiting structure of the guide wheel is preferably not limited to annular groove, and can also be set as flange, guide rail or the like according to the actual situation; the limiting groove is preferably not limited to C-shaped limiting groove, and any groove / rail structure that can constrain the movement path of the cut piece falls within the protection range, such as U-shaped limiting groove or limiting guide rail structure.

[0039] Using the technical solution of this embodiment, this application positions the edge of the cut piece by a limiting groove, so that the edge of the cut piece is aligned with the right side of the drive wheel 4; positions the zipper tooth edge by a limiting structure of the guide wheel 21, so that the zipper tooth edge is aligned with the right side of the drive wheel 4; drives the pressure wheel 33 to press down, so that the cut piece and the zipper are pressed tightly between the drive wheel and the pressure wheel; drives the drive wheel 4 to rotate, synchronously conveying the cut piece and the zipper to achieve rapid and accurate alignment and bonding of their edges.

[0040] In this embodiment, the collaborative working mechanism of each component of the processing equipment is described in detail below: The frame 1, as the core support structure of the entire processing equipment, can be made of high-strength aluminum alloy, which not only ensures the stability of the equipment but also reduces the overall weight. It is fixed to any edge of the worktable 10 by clamping with the fixing clip 11, which facilitates the installation and disassembly of the equipment.

[0041] The guide wheel 21 in the positioning component 2 includes a first guide wheel 211 and a second guide wheel 212. The cooperation of the first guide wheel 211 and the second guide wheel 212 forms a multi-stage guiding structure. The first guide wheel 211 is close to the chain disc 7, and the groove wall of its annular groove is finely polished to a surface roughness of Ra0.8, which effectively reduces the frictional resistance of the zipper during the pulling process and ensures that the zipper is smoothly transported along the predetermined path. The second guide wheel 212 is close to the pressure roller 33, further precisely guiding the zipper and ensuring that the zipper teeth are accurately aligned with the right side of the drive wheel 4.

[0042] Combination Figure 5 , Figure 6 As shown, the guide wheel 21 and guide limiter 22 of the positioning component 2 mainly function to achieve alignment and limitation between the zipper and the edge of the bag body piece 9. The guide limiter 22 is a block structure and is set on the front of the frame 1. A limiting groove is opened on the guide limiter 22, which is open on one side and closed on the other side, namely a C-shaped limiting groove 220. The inner sidewall 221 of the C-shaped limiting groove is aligned with the right side of the drive wheel 4. The welding edge of the bag body piece 9 enters close to the inner sidewall 221 of the C-shaped limiting groove. Under the limiting action of the C-shaped limiting groove, the welding edge of the bag body piece 9 is aligned with the right side of the drive wheel 4. The zipper is pulled out from the chain disc 7, passes through the guide wheel 21 and enters between the pressure wheel 33 and the drive wheel 4. The zipper teeth are aligned with the right side of the drive wheel. The zipper teeth 81 pass through the annular receiving groove 330 on the right side of the pressure wheel 33, realizing automatic and rapid alignment between the edge of the zipper teeth and the welding edge of the bag body piece.

[0043] Combination Figure 3 , Figure 4 As shown, the pressure assembly 3 includes a pressure device 31, a pressure rod 32, a pressure roller 33, and a guide block 320. The pressure device 31 is located at the top of the frame 1 and includes a rotating handle 311. Driven by the rotating handle, pressure is stably provided to the pressure device 31 by utilizing spring pressure and structural dead-point characteristics. The pressure rod 32 drives the pressure roller 33 to move vertically up and down. Figure 4 The middle arrow indicates the up and down movement direction, ensuring that the zipper and the bag body piece are subjected to uniform and continuous force during the welding process. Two guide blocks 320 are provided, respectively located near the two ends of the pressure rod 32. The guide blocks are fixed to the left side of the frame 1, and their main function is to restrict the movement path of the pressure rod, ensuring that the pressure rod 32 can only move in the vertical direction.

[0044] Furthermore, an annular receiving groove 330 is provided on the right side of the pressure roller 33. The annular receiving groove 330 is used to allow the zipper teeth 81 to pass through during the zipper welding process, ensuring that the zipper teeth are intact and undamaged during the welding operation, and avoiding them from being crushed.

[0045] The drive wheel 4 is fixed directly below the pressure wheel 33. The outer dimensions of the drive wheel 4 are the same as those of the pressure wheel 33. The center of the drive wheel 4 and the center of the pressure wheel 33 are collinear in the vertical direction. The drive wheel 4 is the driving wheel, driven by a motor, and its speed is adjustable. The drive wheel 4 rotates clockwise for feeding and counterclockwise for unloading.

[0046] Place the bag body piece 9 and zipper 8 between the pressure roller 33 and the drive roller 4. After the pressure roller 33 presses down, it can press the bag body piece 9 and zipper 8 between the pressure roller 33 and the drive roller 4. When the drive roller 4 rotates, it can drive the pressed bag body piece and zipper to move together, so as to achieve reliable, stable and precise fitting processing.

[0047] Combination Figure 1 , Figure 9 , Figure 10 As shown, the welding heating mechanism 6 includes a multi-degree-of-freedom articulated arm 60 and a heating block 67 located at its end. The head of the heating block 67 is designed with an upper surface concave arc structure 671 and a lower surface concave arc structure 672. The curvature of the upper surface concave arc structure 671 and the lower surface concave arc structure 672 is the same as that of the pressure roller 33 and the drive roller 4, respectively. That is, the radius of curvature of the upper surface concave arc structure 671 and the lower surface concave arc structure 672 is the same as that of the pressure roller 33 and the drive roller 4, respectively. After the pressure roller 33 presses against the drive roller 4, the upper surface of the head of the heating block 67 is close to the surface of the pressure roller 33, and the lower surface is close to the surface of the drive roller 4, thereby realizing rapid heating between the zipper and the cut piece.

[0048] Specifically, such as Figure 1 As shown, the multi-degree-of-freedom articulated arm 60 includes, but is not limited to, a cantilever 61, an upper articulated arm 62, a middle articulated arm 63, and a lower articulated arm 64. One end of the cantilever 61 is fixedly connected to the top of the frame, and the other end is connected to the upper articulated arm 62. The upper articulated arm 62 is connected to the middle articulated arm 63, and the middle articulated arm 63 is connected to the lower articulated arm 64. There is a joint point between each articulated arm. The joint point consists of two discs. There is a connector between the two discs. The connector can control the force required for the two discs to rotate relative to each other. A brake or damping structure is provided at the connection between the connector and the disc. The rotation control of the disc is achieved by controlling the tightness of the disc and the connector through screws or other means. Through the connector, the two discs can rotate 360° around the joint point, which facilitates the flexibility of adjusting the position of the heating block 67 and ensures that the heating block can be accurately adjusted to the optimal position between the zipper and the cut piece.

[0049] An operating handle 65 and a heating block 67 are connected to the end of the lower joint arm 64. A heat insulation block 66 is provided on the outside of the heating block 67. A heating rod is provided inside the heating block 67 and a temperature sensor 68 is provided on the left side of the heating block 67. The temperature of the heating block can be monitored in real time and the monitoring results are fed back to the temperature controller to enable the heating block to work in a constant temperature state.

[0050] Furthermore, the multi-degree-of-freedom articulated arm 60 has a hollow internal structure to allow for the concealed routing of cables.

[0051] The main function of the handle 65 is to control the rotation of the multi-degree-of-freedom articulated arm and adjust the position of the heating block 67. The handle 65 is located at the end of the heat insulation block 66 away from the heating block 67 to prevent burns to the operator.

[0052] The peeling wheel assembly 5 includes a drive wheel 51 and a driven wheel 52. The drive wheel 51 is driven by a variable frequency motor. The speed of the motor can be adjusted in real time according to the rotation speed of the drive wheel and the chain wheel. This is used to simultaneously remove the zipper protective film while the zipper is attached to the cut piece.

[0053] Example 2 This embodiment uses the zipper bonding processing equipment from Embodiment 1 to achieve the detailed process of heat bonding between the zipper and the pouch body piece, as follows: When performing the heat bonding operation between the zipper and the pouch body piece, firstly, the frame 1 is securely clamped to the edge of the worktable 10 using the fixing clamp 11. The clamping function of the fixing clamp 11 ensures that the frame 1 remains stable throughout the processing and does not shift. Next, based on the material and characteristics of the zipper and the pouch body piece, as well as the processing requirements, the working parameters are precisely set in the control system. These working parameters mainly include the heating temperature of the heating block 67 and the rotation speed of the drive wheel 4. A suitable heating temperature allows the adhesive surface of the zipper to fully melt, achieving a firm bond with the pouch body piece; while an appropriate rotation speed of the drive wheel 4 ensures a smooth and efficient feeding process.

[0054] Prepare the required bag body pieces 9 and zippers 8, and neatly wrap the zippers 8 around the chain plate 7 on the back of the frame 1. During the wrapping process, ensure that the zipper teeth 81 of the zipper 8 are located on the right side of the chain plate 7, and that the heat-sealed or adhesive side faces outwards, for subsequent welding operations.

[0055] Then, the bag body piece 9 is slowly moved through the C-shaped limiting groove 220 of the guide limiter 22 located on the front of the frame 1. During this process, the operator must carefully adjust the position of the bag body piece 9 so that its edge is tightly abutting against the inner wall 221 of the C-shaped limiting groove 220, and ensure that the edge of the bag body piece 9 is aligned with the right side of the drive wheel 4. The C-shaped limiting groove 220 of the guide limiter 22 plays a precise limiting role, ensuring that the position of the bag body piece 9 is accurate during processing.

[0056] The zipper 8 is smoothly pulled out from the chainring 7, allowing it to pass smoothly through the annular groove of the guide wheel 21. The guide wheel 21 includes a first guide wheel 211 near the chainring 7 and a second guide wheel 212 near the pressure wheel 33. The width of the annular groove on both wheels matches the width of the zipper 8, and the inner wall of the right side of the annular groove is on the same plane as the right side of the drive wheel 4. In this way, guided by the guide wheel 21, the zipper 8 can move along a predetermined path, while aligning the teeth of the zipper 8 with the right side of the drive wheel 4, ensuring the positional accuracy of the zipper 8 in subsequent processing.

[0057] Next, operate the rotating handle 311 of the pressure device 31 and rotate it downwards. At this time, under the action of the pressure device 31, the pressure rod 32 drives the pressure roller 33 to move vertically downwards, tightly pressing the bag body piece 9, the zipper 8, and the drive wheel 4 together. The annular receiving groove 330 on the right side of the pressure roller 33 can accommodate the zipper teeth 81, ensuring that the zipper teeth 81 will not be damaged during the pressure process.

[0058] The heating block 67 is precisely adjusted between the zipper 8 and the pouch body piece 9 using the multi-degree-of-freedom articulated arm 60 of the rotary welding heating mechanism 6, including a cantilever 61, an upper articulated arm 62, a middle articulated arm 63, and a lower articulated arm 64. The upper and lower surfaces of the head of the heating block 67 have a concave arc structure, and their curvature is the same as that of the pressure roller 33 and the drive roller 4, allowing them to fit tightly against the surfaces of the pressure roller 33 and the drive roller 4. After the position is adjusted, the upper surface of the head of the heating block 67 is close to the adhesive surface of the zipper 8, and the lower surface is close to the pouch body piece 9, providing a stable heat source for thermal bonding.

[0059] The drive wheel 4 is activated and rotated clockwise to begin the welding and bonding feeding process. During feeding, the zipper 8 is automatically fed by the chain disc 7. Thanks to the free rotation and damping function of the chain disc 7, the zipper 8 is stably supplied. The pouch body piece 9 is fed manually. The operator only needs to keep the edge of the pouch body piece 9 tightly against the inner wall 221 of the C-shaped limiting groove 220 during feeding to ensure the bonding accuracy between the pouch body piece 9 and the zipper 8. At the same time, the temperature sensor 68 installed on the side of the heating block 67 monitors the temperature of the heating block 67 in real time and feeds the monitoring data back to the temperature controller to ensure that the heating block 67 operates under a constant temperature, thereby ensuring the quality of heat bonding.

[0060] When material needs to be ejected, control the drive wheel 4 to rotate counterclockwise to eject unprocessed or adjusted material.

[0061] Example 3: This embodiment uses the zipper bonding processing equipment from Embodiment 1 to achieve the detailed process of cold bonding the zipper to the pouch body piece: For the cold bonding operation of the zipper and the bag body piece, the frame 1 is first fixed to the edge of the worktable 10 by the fixing clamp 11. Since it is a cold bonding, only the welding speed related parameters need to be set in the control system, including the speed of the drive wheel 4, the speed of the chain 7, and the speed of the drive wheel 51 and the driven wheel 52 of the peeling wheel set 5. There is no need to set the heating temperature, that is, there is no need to use the welding heating mechanism 6.

[0062] Prepare the pouch body piece 9 and the zipper 8. Wrap the zipper 8 around the chain wheel 7, ensuring that the edge of the zipper teeth 81 is on the right side of the chain wheel 7 and that the adhesive side of the zipper 8 faces outward. Next, guide the pouch body piece 9 through the C-shaped limiting groove 220 of the guide limiter 22, aligning its edge with the inner wall 221 of the C-shaped limiting groove 220 and with the right side of the drive wheel 4. Then, pull the zipper 8 out of the chain wheel 7, passing it through the annular groove of the guide wheel 21, aligning the edge of the zipper teeth 8 with the right side of the drive wheel 4, with the zipper teeth 81 located within the annular groove on the right side of the drive wheel 4.

[0063] Peel off the protective film 80 on the adhesive surface of the zipper 8 and introduce the protective film 80 into the drive wheel 51 and driven wheel 52 of the peeling wheel assembly 5. During the cold bonding process, the rotational speed of the drive wheel 51 and driven wheel 52 of the peeling wheel assembly 5 is matched with the rotational speed of the drive wheel 4 and the sprocket 7. This allows the protective film 80 of the zipper 8 to be removed synchronously and reliably while welding and feeding, preventing the adhesive surface of the zipper 8 from being exposed to air for a long time and ensuring the bonding strength.

[0064] Rotating the handle 311 of the operating pressure device 31 downwards causes the pressure rod 32 to move the pressure roller 33 downwards, pressing the bag body piece 9, zipper 8, and drive wheel 4 together. Starting the drive wheel 4 to rotate clockwise enables welding feeding. The zipper 8 is automatically fed by the chain disc 7, while the bag body piece 9 is fed manually or automatically. During feeding, the welding edge of the bag body piece 9 is kept tightly against the inner wall 221 of the C-shaped limiting groove 220 of the guide limiter 22 to ensure bonding quality. If material removal is required, simply control the drive wheel 4 to rotate counterclockwise.

[0065] Example 4 like Figure 2As shown, this embodiment provides a zipper bonding processing system. The system includes the zipper bonding processing equipment described in Embodiment 1 and a control system for controlling the stable operation of the equipment. The control system includes a controller device 100, which is used to configure and adjust the rotational speed and / or heating temperature of the processing equipment according to actual conditions. When the processing equipment is used for cold bonding of zippers, the control system is used to adjust and control the rotational speed of the drive wheel, the rotational speed of the chain wheel, and the rotational speed of the peeling wheel. When the processing equipment is used for hot bonding of zippers, the control system is used to adjust and control the rotational speed of the drive wheel, the rotational speed of the chain wheel, and the heating temperature of the heating block. The controller device 100 receives temperature signals from the temperature sensor 68 and controls the operating status of the motor of the drive wheel 4, the motor of the peeling wheel assembly 5, the heater of the heating block 67, and the damping or drive device of the chain wheel 7 according to the set operating parameters.

[0066] It should be noted that the specific module structure of the control system is existing technology and will not be elaborated upon here.
