Description

Technical Field

[0001] The present application relates to the technical field of processing equipment, and in particular to a zipper fitting processing equipment, system, processing method and processing technology, which is preferably used for the rapid fitting processing of the edge of a flexible material (such as an aerostat capsule) sheet and a zipper. Background Art

[0002] The weld seam processing of the aerostat bladder panels is crucial in the manufacturing process. Currently, the most widely used bladder weld processing methods utilize intermittent heat sealing equipment or continuous welding equipment, relying on operators and equipment to position the weld edges of the bladder panels, hot press forming, and cooling to finalize the shape.

[0003] However, this method of processing the bladder weld seam has the problem of low efficiency and insufficient precision in manual positioning of the airship bladder weld seam. To solve these problems, the applicant, after a long period of research and practice, has proposed an efficient welding process for airship bladders. The process mainly includes two processing steps: zipper fitting and positioning processing and welding processing of two adjacent bladder pieces after zipper fitting. That is, first, a single-sided zipper is reliably installed and fitted on the edge of the bladder piece; then, in a subsequent process, welding processing equipment is used to weld the two adjacent zippered pieces together in the heat sealing area on the other side of the bladder piece where the zipper is not fitted, using a welding tape to form a reliable weld. The process has the advantages of fast and high precision in piece weld positioning and high welding processing efficiency.

[0004] However, the existing technology lacks specialized equipment and related technologies that can quickly attach zippers to the edges of bag panels. Zipper-to-panel attachment processes in other fields also face similar problems, such as low attachment precision, low efficiency, and difficulty in ensuring attachment quality.

[0005] In order to achieve the above objectives, it is urgent for those skilled in the art to develop a zipper fitting processing equipment that can quickly, accurately and reliably fit a single-sided zipper to the edge of a bag body panel. Summary of the Invention

[0006] The purpose of the present invention is to provide a processing device and method for aligning and fitting the edges of zippers and cutting pieces. By arranging the right side of the driving 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 difficult edge alignment and unreliable fitting of zippers with bag cutting pieces or other cutting pieces are solved, and the zippers and cutting pieces are fast, accurate and reliable fitting is achieved, thereby improving processing efficiency and quality.

[0007] The technical solution adopted by the present invention to solve its technical problems is: on the one hand, a zipper fitting processing equipment is provided, which processing equipment includes a frame and a positioning assembly, a pressure assembly and a driving wheel arranged on the frame; the positioning assembly includes a guide wheel and a guide limiter arranged on the frame; the guide wheel is provided with a limiting structure adapted to match the width of the zipper, and the guide limiter is provided with a limiting groove for limiting the moving path of the cutting piece, the edge of the cutting piece abuts against the inner side wall of the limiting groove, and the sprocket edge of the zipper abuts against the right side wall of the limiting structure; the pressure assembly includes a pressure device, a pressure rod and a pressure wheel, and the pressure device drives the pressure rod to drive the pressure wheel to move vertically; the driving wheel and the pressure wheel cooperate to drive the zipper and the cutting piece to move synchronously; the right side surface of the driving wheel, the right side surface of the pressure wheel, the inner side wall of the limiting groove, and the right side wall of the limiting structure are coplanar and arranged on the same vertical plane, so that the sprocket edge of the zipper is aligned with the edge of the bag cutting piece.

[0008] Furthermore, the limiting structure is an annular groove provided 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 provided on the limiting block is a C-shaped limiting groove.

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

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

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

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

[0013] Furthermore, the processing equipment also includes a stripping wheel set for cold bonding and / or a welding heating mechanism for hot bonding, and the stripping wheel set 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 arranged 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 wheel and the driving wheel.

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

[0016] Furthermore, the processing equipment also includes a chain plate, which is arranged on the back of the frame and is used to store zippers. The chain plate can rotate freely and has a damping function.

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

[0018] Furthermore, the guide limiter C-shaped limit groove is used to limit the moving path of the cut piece. Its structural form is a C-shaped channel structure composed of upper and lower baffles and a single-side inner wall. It is made of rigid material and can resist deformation caused by the weight of the bag body cut piece.

[0019] Optionally, the C-shaped limit groove of the guide limiter of the present invention can also be a C-shaped rod structure or a C-shaped spring clip structure composed of upper and lower cantilever rods, which can achieve the same purpose of limiting the moving path of the cutting piece.

[0020] On the other hand, the present application provides a zipper laminating processing method, which is implemented by the above-mentioned zipper laminating processing equipment, comprising:

[0023] Driving the pressing wheel downward to press the cut piece and the zipper tightly between the driving wheel and the pressing wheel;

[0024] The driving wheel is driven to rotate, synchronously conveying the cut pieces and zippers to achieve edge fitting.

[0025] Furthermore, the zipper laminating processing method specifically includes the following steps:

[0026] Step S1: prepare the cut pieces and the zipper, and wrap the zipper around the chain disc so that the sprocket teeth of the zipper are located on the right side of the chain disc and the heat-sealed surface or the adhesive surface faces outward;

[0027] Step S2: passing the cut piece through the C-shaped limiting groove of the guide limiter, with the edge of the cut piece abutting against the inner side wall of the C-shaped limiting groove, and with the edge of the cut piece aligned with the right side of the driving wheel;

[0028] Step S3: Pull the zipper out of the chain disc, pass it through the annular groove of the guide wheel, and align the sprocket edge of the zipper with the right side of the driving wheel;

[0029] Step S4: If heat bonding is used, the heating block is adjusted between the zipper and the cut piece by rotating the multi-degree-of-freedom articulated arm so that the upper surface of the heating block head is close to the adhesive surface of the zipper and the lower surface is close to the cut piece;

[0030] If it is cold lamination, tear off the protective film on the adhesive surface of the zipper, and pass the protective film through the driving wheel and the driven wheel of the peeling wheel set to achieve synchronous removal of the zipper protective film;

[0031] Step S5: Rotate the rotary handle of the press to move the pressing rod downward to press the cutting piece, zipper and driving wheel together;

[0032] Step S6, start the driving wheel to rotate clockwise to realize welding and bonding feeding. The zipper is automatically fed by the chain disk, and the cut piece is fed through the C-shaped limiting groove. During the feeding process, the edge of the cut piece is closely attached to the inner wall of the C-shaped limiting groove.

[0033] Furthermore, during the thermal bonding process, the temperature sensor monitors the temperature of the heating block in real time and feeds back to the temperature controller to ensure that the heating block operates at a constant temperature.

[0034] Furthermore, the driving wheel rotates counterclockwise to withdraw the material.

[0035] Furthermore, during the cold lamination process, the rotation speeds of the driving wheel and the driven wheel of the stripping wheel set match the rotation speeds of the driving wheel and the chain disc.

[0036] On the other hand, the present application further provides a zipper laminating processing system, which includes the above-mentioned zipper laminating processing equipment and a control system, wherein the control system is configured to adjust the rotation speed and / or heating temperature of the driving wheel.

[0037] Furthermore, during cold lamination, the control system is used to adjust and control the speed of the driving wheel, the speed of the chain disc and the speed of the stripping wheel;

[0038] During thermal bonding, the control system is used to adjust and control the rotation speed of the driving wheel, the rotation speed of the chain disc and the heating temperature of the heating block.

[0039] On the other hand, the present application further provides a zipper laminating process, which includes the above-mentioned zipper laminating method and further includes:

[0040] Before the zipper laminating process, the frame is fixed to the workbench by a fixing clamp, and the working parameters are set, which include but are not limited to the heating temperature of the heating block, the speed of the driving wheel, the speed of the chain disk and the speed of the stripping wheel; if it is hot laminating, the heating temperature of the heating block and the speed of the driving wheel and the speed of the chain disk are set; if it is cold laminating, only the speed of the driving wheel, the speed of the chain disk and the speed of the stripping wheel are set.

[0041] Compared with the existing technology, the advantages of the technical solution of this application are as follows:

[0042] Through the zipper fitting processing equipment, system, processing method and processing technology provided by the present application, a coplanar positioning structure is formed by arranging the right side of the driving 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 in the same plane to solve the technical problems of difficult edge alignment and unreliable fitting of the zipper with the bag piece or other pieces, thereby achieving fast, accurate and reliable fitting of the zipper and the piece, and improving processing efficiency and quality.

[0043] Specifically, the present application provides a zipper fitting processing device, which is mainly used to quickly, accurately and reliably fit a single-sided zipper to the edge of a bag body piece, forming a bag body piece with a zipper on the edge and normal zippering function. The processing device includes a frame, a positioning assembly, a pressure assembly and a driving wheel; the positioning assembly includes a guide wheel for guiding and limiting the zipper and a limiting groove on the guide limiter for limiting the moving path of the piece. Through the coordinated action of the guide limiter and the guide wheel, the zipper and the bag body piece are precisely aligned; under the action of the pressure of the pressure assembly, the pressure rod drives the pressure wheel to move vertically up and down, and the zipper and the piece are driven to move synchronously through the matching and compressed driving wheel working surface and the pressure wheel working surface; further, by arranging the right side surface of the driving wheel, the right side surface of the pressure wheel, the inner side wall of the limiting groove, and the right side wall of the guide wheel annular groove on the same vertical plane, the zipper and the piece can cooperate to achieve the alignment of the zipper's chain tooth edge with the piece edge during the fitting movement.

[0044] Furthermore, by fixing a peeling wheel assembly including a driving wheel and a driven wheel on the left side of the frame, the protective film can be automatically removed while the zipper moves. This removal method greatly reduces the exposure time of the zipper adhesive surface to the air, avoiding the adsorption of large amounts of dust and other particles in the air on the adhesive surface, thereby reducing the bonding strength.

[0045] This application combines the processing method of the applied processing equipment to achieve fast, accurate and reliable bonding of zippers and cut pieces. Through hot bonding and cold bonding, it meets the processing requirements of different types of zippers, greatly improves processing efficiency and reduces manual labor intensity.

[0071] Example 1

[0072] See also Figure 1 、 Figure 2 As shown, this embodiment provides a zipper fitting processing equipment, which includes a frame 1 and a positioning component 2, a pressure component 3 and a driving wheel 4 arranged on the frame 1; the positioning component 2 includes a guide wheel 21 and a guide limiter 22 arranged on the frame 1; the guide wheel 21 is provided with a limiting structure matching the zipper width, and the limiting structure is an annular groove opened on the guide wheel 21, and the guide limiter 22 is provided with a limiting groove for limiting the moving path of the bag body piece 9, and the structure of the limiting groove is preferably a C-shaped limiting groove 220, and the edge of the bag body piece 9 abuts against the inner side wall 221 of the C-shaped limiting groove, and the sprocket edge of the zipper abuts against the right side wall of the annular groove; the pressure component 3 includes a pressure 31, a pressure rod 32 and a pressure wheel 33, the pressure device 31 and the pressure wheel 33 are respectively arranged at the two ends of the pressure rod 32, that is, the pressure device 31 is arranged on the top of the frame 1 and acts on one end of the pressure rod 32, and the pressure wheel 33 is arranged at the other end of the pressure rod 32. Under the action of the pressure device 31, the pressure rod 32 drives the pressure wheel 33 to move in the vertical direction; the working surfaces of the driving wheel 4 and the pressure wheel 33 jointly drive the zipper and the cut piece to move synchronously; wherein, the right side surface of the driving wheel 4, the right side surface of the pressure wheel 33 and 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 coplanar and arranged on the same vertical plane to form a coplanar positioning structure, so that the sprocket edge of the zipper is aligned with the edge of the cut piece.

[0073] It should be noted that the "coplanar setting" of this embodiment can be achieved through laser calibration, mechanical stops or visual positioning; the limiting structure of the guide wheel is preferably not limited to annular grooves, and can also be set to flanges, guide rails, etc. according to actual conditions; the limiting groove is preferably not limited to C-shaped limiting grooves, and any groove / rail structure that can constrain the moving path of the cut piece falls within the protection range, such as U-shaped limiting grooves or limiting guide rail structures.

[0074] Utilizing the technical solution of this embodiment, the present application positions the edge of the cutting piece through the limiting groove so that the edge of the cutting piece is aligned with the right side surface of the driving wheel 4; positions the zipper tooth edge through the limiting structure of the guide wheel 21 so that the zipper tooth edge is aligned with the right side surface of the driving wheel 4; drives the pressing wheel 33 downward to press the cutting piece and the zipper tightly between the driving wheel and the pressing wheel; drives the driving wheel 4 to rotate, and synchronously transports the cutting piece and the zipper to achieve fast and accurate alignment and fitting of the edges of the two.

[0075] In this embodiment, the collaborative working mechanism of each component of the processing equipment is described in detail as follows:

[0076] The frame 1 serves as the core supporting structure of the entire processing equipment. Its material can preferably be made of high-strength aluminum alloy, which not only ensures the stability of the equipment but also reduces the overall weight. It is clamped and fixed at any edge position of the workbench 10 by the fixing clamp 11, which facilitates the installation and disassembly operations of the equipment.

[0077] The guide wheels 21 in the positioning assembly 2 include a first guide wheel 211 and a second guide wheel 212. The first guide wheel 211 and the second guide wheel 212 cooperate to form a multi-stage guide structure. The first guide wheel 211 is located near the chain plate 7. The annular groove of the first guide wheel 211 has been finely polished to a surface roughness of Ra0.8, effectively reducing friction during the zipper's removal process while ensuring smooth transport along the intended path. The second guide wheel 212, located near the pressure wheel 33, further precisely guides the zipper, ensuring that the zipper teeth are accurately aligned with the right side of the drive wheel 4.

[0078] Combine Figure 5 、 Figure 6 As shown, the guide wheel 21 and the guide limiter 22 of the positioning assembly 2 have the main function of realizing the alignment and limitation of the edge of the zipper and the bag body piece 9. The guide limiter 22 is a block structure and is arranged on the front side of the frame 1. A limiting groove is provided on the guide limiter 22, one side is open and the other side is closed, that is, a C-shaped limiting groove 220. The inner side wall 221 of the C-shaped limiting groove is aligned with the right side of the driving wheel 4, and the welding edge of the bag body piece 9 enters close to the inner side wall 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 driving wheel 4, and the zipper is pulled out from the chain disk 7, passes through the guide wheel 21 and enters between the pressure wheel 33 and the driving wheel 4, and the zipper sprockets are aligned with the right side of the driving wheel. The zipper sprockets 81 pass through the annular accommodating groove 330 on the right side of the pressure wheel 33, thereby realizing automatic and rapid alignment of the zipper sprocket teeth edge and the welding edge of the bag body piece.

[0079] Combine Figure 3 、 Figure 4 As shown, the pressure assembly 3 includes a pressure device 31, a pressure rod 32, a pressure wheel 33 and a guide block 320. The pressure device 31 is set at the top of the frame 1 and includes a rotating handle 311. Under the drive of the rotating handle, the spring pressure and the structural dead point characteristics are used to stably provide pressure for the pressure rod 31. The pressure rod 32 drives the pressure wheel 33 to move vertically up and down, as shown in FIG. Figure 4 The middle arrows indicate the direction of up and down movement, ensuring uniform and continuous force is applied to the zipper and the body panels during the welding process. Two guide blocks 320 are provided, one located near each end of the pressure rod 32. These guide blocks are fixed to the left side of the frame 1 and primarily function to limit the movement of the pressure rod, ensuring that it can only move in the vertical direction.

[0080] Furthermore, an annular receiving groove 330 is provided on the right side of the pressing wheel 33. The annular receiving groove 330 is used for allowing the zipper teeth 81 to pass through during the zipper welding process, thereby ensuring that the zipper teeth are intact and avoid being crushed during the zipper welding operation.

[0081] The driving wheel 4 is fixed directly below the pressing wheel 33. The outer dimensions of the driving wheel 4 are the same as those of the pressing wheel 33. The center of the driving wheel 4 is collinear with the center of the pressing wheel 33 in the vertical direction. The driving wheel 4 is an active wheel, driven by a motor, and the speed is adjustable. The driving wheel 4 rotates clockwise for feeding and counterclockwise for withdrawing.

[0082] The bladder body piece 9 and the zipper 8 are placed between the pressing wheel 33 and the driving wheel 4. When the pressing wheel 33 is pressed down, the bladder body piece 9 and the zipper 8 can be pressed between the pressing wheel 33 and the driving wheel 4. When the driving wheel 4 rotates, the pressed bladder body piece and the zipper can be driven to move together, thereby realizing reliable, stable and precise fitting processing.

[0083] Combine 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 arranged at the end thereof, and 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 are respectively the same as the curvature of the pressing wheel 33 and the driving wheel 4, that is, the curvature radius of the upper surface concave arc structure 671 and the lower surface concave arc structure 672 are respectively the same as the curvature radius of the pressing wheel 33 and the driving wheel 4. After the pressing wheel 33 presses the driving wheel 4, the upper surface of the head of the heating block 67 is close to the surface of the pressing wheel 33, and the lower surface is close to the surface of the driving wheel 4, thereby realizing rapid heating between the zipper and the cut piece.

[0084] Specifically, if 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, and the joint point is composed of two discs. There is a connector between the two discs, and 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, and the tightness of the disc and the connector is controlled by screws or other means to realize the rotation control of the disc. Through the connector, the two discs can realize 360° rotation around the joint point, thereby facilitating the flexibility of position adjustment of the heating block 67, ensuring that the heating block can be accurately adjusted to the optimal position between the zipper and the cut piece.

[0085] A handling handle 65 and a heating block 67 are connected to the end of the lower joint arm 64, an insulating 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 can be fed back to the temperature controller to enable the heating block to operate at a constant temperature.

[0086] Furthermore, the interior of the multi-degree-of-freedom articulated arm 60 is a hollow structure, which is used to pass cables and realize invisible cable routing.

[0087] The main function of the setting of the handle 65 is to control the rotation of the multi-degree-of-freedom articulated arm through the handle 65 to adjust the position of the heating block 67, and the handle 65 is set at one end of the insulation block 66 away from the heating block 67 to prevent the operator from being scalded.

[0088] The stripping wheel group 5 includes a driving wheel 51 and a driven wheel 52. The driving 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 driving wheel and the chain disc, so as to simultaneously remove the zipper protective film while achieving the fitting of the zipper and the cut piece.

[0089] Example 2

[0090] This embodiment uses the zipper laminating equipment of the first embodiment to achieve the detailed process of thermal laminating the zipper and the bag body panel as follows:

[0091] When thermally bonding the zipper to the bladder body, the frame 1 is first securely clamped to the edge of the workbench 10 using the retaining clamp 11. The clamping function of the retaining clamp 11 ensures that the frame 1 remains stable and prevents displacement throughout the entire process. Next, the control system precisely sets operating parameters based on the materials, characteristics, and processing requirements of the zipper and bladder body. These parameters primarily include the heating temperature of the heating block 67 and the rotational speed of the drive wheel 4. The appropriate heating temperature fully melts the adhesive surface of the zipper, achieving a secure bond with the bladder body; while the appropriate rotational speed of the drive wheel 4 ensures a smooth and efficient feeding process.

[0092] Prepare the required bladder body pieces 9 and zipper 8, and neatly wind the zipper 8 around the chain disc 7 on the back of the frame 1. During the winding process, ensure that the zipper teeth 81 of the zipper 8 are on the right side of the chain disc 7, and the heat-sealed surface or adhesive surface faces outward for subsequent welding operations.

[0093] The bladder piece 9 is then slowly moved through the C-shaped retaining groove 220 of the guide stopper 22, located on the front of the frame 1. During this process, the operator must carefully adjust the position of the bladder piece 9 so that its edge closely abuts the inner wall 221 of the C-shaped retaining groove 220 and aligns the edge of the bladder piece 9 with the right side of the drive wheel 4. The C-shaped retaining groove 220 of the guide stopper 22 provides a precise retaining function, ensuring that the bladder piece 9 remains accurately positioned during processing.

[0094] The zipper 8 is smoothly pulled out of the sprocket 7, passing smoothly through the annular groove of the guide wheel 21. The guide wheels 21 include a first guide wheel 211 located near the sprocket 7 and a second guide wheel 212 located near the pressure wheel 33. The width of the annular groove on these guide wheels matches the width of the zipper 8, and the inner wall of the right side of the annular groove is flush with the right side of the drive wheel 4. This way, guided by the guide wheels 21, the zipper 8 can move along the prescribed path, while aligning the sprocket edge of the zipper 8 with the right side of the drive wheel 4, ensuring the positional accuracy of the zipper 8 during subsequent processing.

[0095] Next, operate the rotary handle 311 of the press 31 and rotate it downward. Under the action of the press 31, the pressure rod 32 drives the pressure wheel 33 to move vertically downward, tightly pressing the bladder panel 9, zipper 8, and drive wheel 4. The annular receiving groove 330 on the right side of the pressure wheel 33 can accommodate the zipper teeth 81, ensuring that the zipper teeth 81 are not damaged during the pressure process.

[0096] The multi-degree-of-freedom articulated arm 60 of the rotating welding and heating mechanism 6, comprising a cantilever 61, an upper articulated arm 62, a middle articulated arm 63, and a lower articulated arm 64, precisely adjusts the heating block 67 between the zipper 8 and the bladder body panel 9. The upper and lower surfaces of the heating block 67's head are concave arcs, with the same curvature as that of the pressure wheel 33 and the drive wheel 4, ensuring a close fit to the surfaces of the pressure wheel 33 and the drive wheel 4. After proper positioning, the upper surface of the heating block 67's head is positioned adjacent to the adhesive surface of the zipper 8, while the lower surface is positioned adjacent to the bladder body panel 9, providing a stable heat source for thermal bonding.

[0097] Start the drive wheel 4 and rotate it clockwise to begin the welding, laminating, and feeding process. During the feeding process, the zipper 8 is automatically fed by the chain disk 7. Thanks to the chain disk 7's free rotation and damping function, it can stably supply the zipper 8. The bladder piece 9 is manually fed. The operator only needs to keep the edge of the bladder piece 9 close to the inner wall 221 of the C-shaped limit groove 220 during the feeding process to ensure the laminating accuracy of the bladder piece 9 and the zipper 8. At the same time, the temperature sensor 68 installed on the side of the heating block 67 will monitor the temperature of the heating block 67 in real time and feed the monitoring data back to the temperature controller to ensure that the heating block 67 operates at a constant temperature, thereby ensuring the quality of the thermal lamination.

[0098] When the material needs to be withdrawn, the driving wheel 4 is controlled to rotate counterclockwise to withdraw the unprocessed material or the material that needs to be adjusted.

[0099] Example 3:

[0100] This embodiment uses the zipper laminating equipment of the first embodiment to achieve the detailed process of cold laminating the zipper and the bag body panel as follows:

[0101] For cold lamination of the zipper and the bag body, the frame 1 is similarly secured to the edge of the workbench 10 using the fixing clamps 11. Since this is cold lamination, only parameters related to the welding speed need to be set in the control system, including the speed of the drive wheel 4, the speed of the chain plate 7, and the speeds of the driving wheel 51 and the driven wheel 52 of the stripping wheel assembly 5. There is no need to set the heating temperature, which means that the welding heating mechanism 6 is not required.

[0102] Prepare the bladder body piece 9 and zipper 8. Wrap the zipper 8 around the chain disc 7, ensuring that the sprocket teeth 81 are on the right side of the chain disc 7 and the adhesive side of the zipper 8 faces outward. Next, pass the bladder body piece 9 through the C-shaped retaining groove 220 of the guide stopper 22, aligning its edge with the inner wall 221 of the C-shaped retaining groove 220 and the right side of the drive wheel 4. Then, pull the zipper 8 from the chain disc 7, pass it through the annular groove of the guide wheel 21, and align the sprocket edge of the zipper 8 with the right side of the drive wheel 4. The zipper teeth 81 are located in the annular groove on the right side of the drive wheel 4.

[0103] The protective film 80 on the adhesive surface of the zipper 8 is removed and introduced into the driving wheel 51 and the driven wheel 52 of the stripping wheel assembly 5. During the cold bonding process, the rotation speeds of the driving wheel 51 and the driven wheel 52 of the stripping wheel assembly 5 match the rotation speeds of the driving wheel 4 and the chain plate 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.

[0104] The rotary handle 311 of the operator press 31 is rotated downward, and the pressure rod 32 drives the pressure wheel 33 downward, pressing the bladder body piece 9 and zipper 8 against the drive wheel 4. The drive wheel 4 is activated to rotate clockwise to achieve welding and feeding. The zipper 8 is automatically fed by the chain disk 7, and the bladder body piece 9 is fed manually or automatically. During the feeding process, the welded edge of the bladder body piece 9 is always kept close to the inner wall 221 of the C-shaped retaining groove 220 of the guide stopper 22 to ensure a high-quality fit. To return the material, the drive wheel 4 is similarly controlled to rotate counterclockwise.

[0105] Example 4

[0106] like Figure 2As shown, this embodiment provides a zipper laminating processing system, which includes the zipper laminating processing equipment described in Example 1 and a control system for controlling the stable operation of the processing equipment. The control system includes a controller device 100, which is used to configure and adjust the rotation speed and / or heating temperature of the processing equipment according to actual conditions. When the processing equipment is used for cold laminating of zippers, the control system is used to adjust the rotation speed of the drive wheel, the rotation speed of the chain disc, and the rotation speed of the stripping wheel; when the processing equipment is used for hot laminating of zippers, the control system is used to adjust the rotation speed of the drive wheel, the rotation speed of the chain disc, and the heating temperature of the heating block. The controller device 100 receives the temperature signal from the temperature sensor 68 and controls the motor of the drive wheel 4, the motor of the stripping wheel assembly 5, the heater of the heating block 67, and the damping or driving device of the chain disc 7 according to the set working parameters.
