Description

Technical Field

[0001] This invention relates to the field of shaping winged moxibustion patches before packaging, and more particularly to a winged moxibustion patch shaping device. Background Technology

[0002] The wing-type moxibustion patch is long and narrow, with an adhesive area on its bottom surface. The heating inner pack is centrally located in the adhesive area, and the two sides of the bottom surface extend outward to form adhesive wings (referred to as side wings). Since the heating inner pack needs to be in contact with air to generate heat, its outer surface is usually made of breathable non-woven fabric.

[0003] During the production process, the adhesive on the adhesive wings needs to be covered with release paper for protection to facilitate subsequent packaging. However, existing processes cannot cover only a portion of the adhesive wings. Therefore, the moxibustion patch production equipment first uses a roller cutter to cut a whole sheet of release paper with the same shape as the bottom layer, and then uses the adhesive wings to adhere it to the moxibustion patch as a whole. At the same time, the roller cutter pre-cuts the release paper area corresponding to the heating inner package during the cutting process.

[0004] Currently, after the production of winged moxibustion patches is completed, they need to be manually sorted before being transferred to packaging equipment for sealing. This method has the following problems: a. Release paper in the non-adhesive area needs to be removed manually: Since the outer surface of the heating inner package is non-woven fabric, it cannot be bonded to the release paper. After pre-cutting, the release paper in this area still needs to be removed manually, resulting in low shaping efficiency. b. Manual folding and long-term exposure: Before entering the packaging process, the adhesive wings on both sides are usually manually folded before being fed into the multi-channel packaging equipment. This method seriously restricts production efficiency. Moreover, the moxibustion patch is exposed for a long time, and the heating inner package is prone to continuous contact with air and premature reaction failure, which leads to an increase in the defect rate. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention provides a wing-type moxibustion patch forming device that can automatically remove the release paper in the non-adhesive area, fold the two side wings, and realize multi-channel high-efficiency feeding.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wing-type moxibustion patch material preparation device, characterized in that it includes a release paper waste removal mechanism for the glue-free area, a side wing folding mechanism, and a multi-channel conveying mechanism; the release paper waste removal mechanism for the glue-free area includes a release paper adsorption station, a release paper waste discharge station, a release paper waste removal unit, and a conveying plane; the conveying plane passes through the release paper adsorption station; the release paper waste removal unit includes a release paper adsorption component; the release paper adsorption component is used to adsorb the release paper of the glue-free area of ​​the moxibustion patch at the release paper adsorption station and transfer it to the release paper waste discharge station; the side wing folding mechanism includes a material suction and conveying channel and a folding wing unit; the material suction and conveying channel is used for material feeding. The outlet is connected to the discharge end of the conveying plane; the folding wing unit includes a first folding guide plate and a second folding guide plate, which are respectively arranged on both sides of the suction conveying channel. The first folding guide plate is used to make the material wing on the same side fold before the material wing on the other side fold; the multi-channel conveying mechanism includes an adsorption transfer unit and several transversely arranged packaging connection channels; the adsorption transfer unit is connected between the suction conveying channel and the packaging connection channel. The adsorption transfer unit is used to adsorb several materials from the suction conveying channel, change the arrangement of several materials from longitudinal to transverse, and make the wing folded by the second folding guide plate on the material face the entrance of the packaging connection channel.

[0007] This invention utilizes a release paper rejection mechanism in the glue-free zone and a side wing folding mechanism to achieve automatic connection between receiving materials, organizing them, and then sending them out. The release paper adsorption component adsorbs the release paper from the glue-free zone at the release paper adsorption station and transfers it to the release paper waste discharge station, achieving precise removal and automatic waste discharge. In the side wing folding mechanism, the first and second folding guide plates ensure the orderly sequential folding of the two side wings, avoiding mutual interference. The adsorption and transfer unit of the multi-channel conveying mechanism transfers materials between the suction conveying channel and the packaging connection channel, adjusting the bonding arrangement direction and orientation to adapt to the multi-channel requirements of the packaging process and ensuring the outer side wings face the entrance of the packaging connection channel. This allows subsequent limiting components to press down on the outer side wings, effectively preventing the folded side wings from springing back and opening before final sealing. Furthermore, the adsorption and transfer unit ensures a one-to-one correspondence between materials and packaging connection channels. The entire device achieves full automation of rejection, folding, transfer, and distribution, reducing labor costs, improving production efficiency, and eliminating the need for prolonged material exposure, thus significantly reducing the defect rate caused by premature reactions.

[0008] Preferably, the first folding guide plate includes a first twisting surface for folding the material side wings on the same side, and the second folding guide plate includes a second twisting surface for folding the material side wings on the same side, with the first twisting surface located upstream of the second twisting surface. This ensures that the two side wings are folded sequentially, with the later-folded side wings overlapping the earlier-folded side wings, avoiding interference when the two side wings are folded simultaneously, and guaranteeing the neatness and consistency of the folds.

[0009] Preferably, the conveying plane is provided with a plurality of adsorption holes, which are used to adsorb and position the material. The adsorption holes on the conveying plane can adsorb and position the material, preventing the material from shifting during conveying and rejection, ensuring that the release paper adsorption component can accurately align with the non-adhesive area, and improving rejection accuracy and success rate.

[0010] Preferably, the release paper adsorption component includes a lifting suction element, which is connected to the release paper waste discharge drive unit. A release paper waste discharge port is provided at the release paper waste discharge station. The release paper waste discharge drive unit is electrically connected to a controller. The controller, based on the conveying speed of the conveying plane, controls the release paper waste discharge drive unit to move the lifting suction element following the conveying plane to pick up paper, and then moves the lifting suction element above the release paper waste discharge port to discharge waste. The controller controls the release paper waste discharge drive unit to move the lifting suction element synchronously with the conveying plane, achieving follow-up waste removal. This eliminates the need for machine downtime to complete release paper adsorption and waste discharge, enabling continuous production and significantly improving production efficiency. Furthermore, the release paper waste discharge port centrally discharges waste paper, preventing it from scattering and affecting normal equipment operation.

[0011] Furthermore, the release paper rejection unit also includes a lifting moving seat, and the release paper waste discharge drive unit is connected to the lifting moving seat. The lifting suction component is located in the middle of the lifting moving seat, and the lifting moving seat is equipped with positioning components, which are located on both sides of the lifting suction component. In the non-working state, the bottom of the positioning component is lower than the bottom of the lifting suction component. The lifting moving seat can use a lifting power source to drive the positioning components to position the material before the suction component contacts the material, reducing costs. The positioning components contact the material before the lifting suction component to position the material, and then the lifting suction component continues to move down to absorb the release paper in the non-adhesive area, ensuring that the lifting suction component accurately absorbs the release paper in the non-adhesive area.

[0012] Based on the adsorption force of the conveying plane, the release paper adsorption component includes an upper adsorption conveyor belt. This upper adsorption conveyor belt sequentially passes through the release paper adsorption station and the release paper waste discharge station. The upper adsorption conveyor belt is positioned above the conveying plane and inclined upwards along the conveying direction. The minimum gap between the conveying plane and the upper adsorption conveyor belt corresponds to the material thickness. When the material passes through, the adsorption holes on the conveying plane adsorb and position the material. The lower surface of the upper adsorption conveyor belt adsorbs the release paper from the adhesive-free area. Because the upper adsorption conveyor belt is inclined upwards, the release paper is peeled off upwards and transported with the upper adsorption conveyor belt to the release paper waste discharge station for discharge. The structure is simple, and the upper adsorption conveyor belt can operate continuously.

[0013] Preferably, the adsorption and transfer unit includes an adsorption component, a lifting and rotating support, and a following material-picking drive component. The adsorption component is mounted on the lifting and rotating support, which drives the material on the adsorption component to rotate. The following material-picking drive component is driveably connected to the lifting and rotating support and electrically connected to a controller. The controller controls the following material-picking drive component to drive the adsorption component to follow and pick up the material at a speed matching the material conveying channel. The material conveying channel can operate continuously, and the adsorption and transfer unit follows and picks up the material, realizing continuous production of the device.

[0014] Furthermore, the adsorption component is a magnetic suction element, and the adsorption transfer unit also includes a feeding component; the feeding component includes a lifting feeding plate and a pressing drive component. The lifting feeding plate has a clearance notch for the magnetic suction element to pass through, and the pressing drive component drives the lifting feeding plate to press the material on the magnetic suction element into the packaging connection channel. The magnetic suction element can magnetically pick up the material through the iron powder in the heated inner packaging. The structure is simple and reliable, and it will not scratch the outer surface of the material.

[0015] Preferably, a limiting component is provided on the upper side of the packaging connection channel to prevent the side wings from springing back. The limiting component presses down on the outer side wings, ensuring that the side wings will not spring back and spread out during the process of being conveyed to the packaging machine, thus guaranteeing the subsequent packaging quality.

[0016] Preferably, a front wing folding mechanism is provided between the conveying plane and the material conveying channel. The front wing folding mechanism includes an air-blowing working surface and a baffle plate. The air-blowing working surface is used to blow air onto the front wing of the material and make it stand up. The baffle plate, located downstream of the air-blowing working surface, is used to fold the standing front wing downwards. For three-wing materials, the air-blowing working surface first blows air onto the adhesive extension part (front wing) at the front end of the material in the length direction to make it stand up. The moving material folds the standing front wing by passing through the baffle plate, thus achieving the folding of the front wing.

[0017] Preferably, the side wing folding mechanism further includes a shaping unit located downstream of the folding wing unit. The shaping unit includes a pressure roller with elastic pressure, which rolls and shapes the material at the corresponding side wing folding position. The pressure roller rolls along the side wing folding line, utilizing the gap in the adhesive layer between the material's side wing and the heating inner packaging to fold and shape the side wing, preventing subsequent side wing rebound and ensuring packaging quality during the packaging process.

[0018] Preferably, the conveying plane is formed by the outer surface of a telescopic conveyor belt, and the inlet or outlet end of the telescopic conveyor belt is a telescopic end; the frame is provided with a defective product discharge port I, which is correspondingly located below the telescopic part. The telescopic conveyor belt can allow defective products to fall directly by retracting part of the conveyor belt, intercepting defective products before they enter the folding process and preventing them from entering subsequent workstations. Moreover, the telescopic conveyor belt occupies little space.

[0019] Preferably, the bottom of the suction conveyor channel is equipped with a suction-type conveyor belt, and the first folding guide plate and the second folding guide plate are arranged on both sides of the suction-type conveyor belt. There is a waste discharge gap between the suction-type conveyor belt and the multi-channel conveyor unit. A defective product waste discharge port II is provided on the frame corresponding to the waste discharge gap. When defective material is detected, the adsorption-transfer unit stops picking up material, and the suction-type conveyor belt passes through the waste discharge gap to allow the material to fall into the defective product waste discharge port II. The suction-type conveyor belt ensures that the material remains tightly attached to the conveying surface of the first conveyor belt under the force of the folding guide plates on both sides, without shifting, thus ensuring precise folding of the side wings. When defective material is detected, the adsorption-transfer unit does not pick up material, and the suction-type conveyor belt continues to run, sending the defective product out of the waste discharge gap and into the defective product waste discharge port II, achieving the removal of folded defective products.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Figure 1 In the diagram, the X-axis represents the left-right direction, i.e., the horizontal direction; the Y-axis represents the front-back direction (the arrow indicates the material conveying direction), i.e., the vertical direction; and the Z-axis represents the up-down direction, i.e., the vertical direction. Example 1

[0028] See Figure 1 A wing-type moxibustion patch material handling device includes a release paper rejection mechanism 1 for the glue-free area, a side wing folding mechanism 2, and a multi-channel conveying mechanism. The release paper rejection mechanism 1 is used to automatically remove the pre-cut release paper from the glue-free area of ​​the material. The side wing folding mechanism 2 is used to fold the side wings on both sides of the material sequentially. The multi-channel conveying mechanism is used to transfer the folded material in groups to multiple packaging connection channels 31 to adapt to subsequent multi-channel packaging equipment.

[0029] See Figure 2 and Figure 3 The release paper rejection mechanism 1 in the glue-free area includes a release paper adsorption station, a release paper waste discharge station, a release paper rejection unit 13, and a conveying plane 11. The conveying path of the conveying plane 11 passes through the release paper adsorption station. The conveying plane 11 is used to transfer horizontally placed materials to the release paper adsorption station, and the release paper waste discharge station is located on one side of the conveying plane 11. The conveying plane 11 can be a conventional circular conveyor belt or a reciprocating conveying mechanism, etc. To ensure that the material maintains its posture during conveying, the conveying plane 11 is provided with several adsorption holes. These adsorption holes are used to adsorb and position the material, and are connected to a negative pressure source.

[0030] The release paper rejection unit 13 includes a release paper adsorption component 411. The release paper adsorption component 411 adsorbs the release paper from the adhesive-free area at the release paper adsorption station and transfers it to the release paper waste discharge station. There are various methods by which the release paper adsorption component 411 adsorbs the release paper from the adhesive-free area and transfers it to the release paper waste discharge station; see [link to relevant documentation]. Figure 3 In this embodiment, the release paper adsorption component 411 includes a lifting suction component 132, which is connected to the release paper waste discharge drive unit 131. The lifting suction component 132 is a liftable adsorption component. In this embodiment, the lifting suction component includes a cylinder and a suction cup. The suction cup is connected to the output shaft of the cylinder via a mounting rod. Of course, the suction cup can be implemented using other adsorption components, and the cylinder can also be replaced by a motor, etc. In addition, a release paper waste discharge port 12 is provided at the release paper waste discharge station. The release paper waste discharge port 12 is set on the frame 8, and the frame 8 has a release paper waste discharge pipe. This pipe is connected to the release paper waste discharge port 12, which can send the release paper out of the device to avoid the release paper scattering and affecting the normal operation of the device. To ensure continuous operation of the device, the release paper waste removal drive unit 131 is electrically connected to the controller 9. The controller 9 controls the release paper waste removal drive unit 131 to drive the lifting suction component 132 to follow the conveying plane 11 to pick up paper, and drives the lifting suction component 132 to move above the release paper waste discharge port 12 to discharge waste, based on the conveying speed of the conveying plane 11. Preferably, the release paper waste removal drive unit 131 is a servo drive module, which includes a longitudinal servo drive structure and a transverse servo drive structure. The longitudinal servo drive structure drives the release paper waste removal unit to move longitudinally following the conveying plane 11, and the transverse servo drive structure drives the release paper waste removal unit to reciprocate between the conveying plane 11 and the release paper waste discharge port 12. Specifically, a first material arrival sensor is set upstream of the conveying plane 11 to detect the material position. Then, the controller 9 controls the release paper waste removal drive unit 131 to drive the release paper waste removal unit to move above the heat-pressing and move synchronously according to the conveying speed of the conveying plane 11, so that the lifting suction component 132 descends to pick up the release paper in the glue-free area.

[0031] To ensure the lifting suction component 132 accurately adsorbs the release paper from the adhesive-free area, the release paper waste removal unit 13 further includes a lifting moving seat 134, and the release paper waste discharge drive unit 131 is connected to the lifting moving seat 134. The lifting suction component 132 is located in the middle of the lifting moving seat 134, and the lifting moving seat 134 is provided with positioning components 133, which are located on both sides of the lifting suction component 132. In the non-working state, the bottom of the positioning component is lower than the bottom of the lifting suction component 132. The positioning component 133 is used to position the side wings of the material before the lifting suction component contacts the material. The positioning component 133 can be a spring telescopic rod or a positioning rod (when the positioning component 133 is a fixed rod, the lifting suction component 132 needs to have an independent power source). At least two positioning components 133 are provided, corresponding to the two side wings respectively. Alternatively, the positioning component 133 can also be an integrally designed positioning frame, which is sleeved on the main shaft and pressed and reset by a spring. In this embodiment, the positioning component 133 and the lifting suction component 132 can each have their own power source or share a power source. In this embodiment, the lifting moving seat 134 includes a lifting bracket and a sliding seat. The lifting bracket is sleeved on the sliding seat, and a synchronous lifting power source is fixedly installed on the sliding seat. This synchronous lifting power source is connected to the lifting bracket and drives the positioning component 133 and the lifting suction component 132 at the bottom of the lifting bracket to move downwards synchronously until the positioning component 133 presses down on both sides of the material. Then, the lifting suction component 132 moves downwards. During the downward movement of the lifting suction component 132, the positioning component 133 moves upwards and retracts. After the lifting suction component 132 picks up the release paper from the adhesive-free area, it returns to its original position one by one with the positioning component. Alternatively, the lifting suction component 132 can be connected to another power source to drive it downwards to pick up the release paper from the adhesive-free area, after which the positioning component 133 and the lifting suction component 132 return to their original positions. The lifting suction component 132 has an independent design to prevent the release paper rejection unit from putting excessive pressure on the conveyor belt-type conveying plane 11, affecting its tension. To prevent the telescopic positioning component from scratching the outer surface of the heat-pressing material, rollers can be installed at the bottom of the telescopic positioning component to make the telescopic positioning component roll into contact with the heat-pressing material.

[0032] See Figure 4The side wing folding mechanism 2 includes a material suction and conveying channel 21 and a folding wing unit 22. The inlet of the material suction and conveying channel 21 is connected to the outlet of the conveying plane 11. The material suction and conveying channel 21 and the conveying plane 11 are respectively set on different conveying mechanisms and are connected to each other; or, the material suction and conveying channel 21 and the conveying plane 11 can be set on the same conveying mechanism, that is, the conveying plane 11 forms the bottom of the material suction and conveying channel 21. The folding wing unit 22 includes a first folding guide plate 221 and a second folding guide plate 222. The first folding guide plate 221 and the second folding guide plate 222 are respectively arranged on both sides of the material conveying channel 21. The first folding guide plate 221 is used to fold the side wings on the same side as it before the side wings on the side of the second folding guide plate 222. The material moves between the first folding guide plate 221 and the second folding guide plate 222. The two side wings of the material are guided to fold by the guide surfaces of the first folding guide plate 221 and the second folding guide plate 222, respectively. For ease of understanding, the side wings on the corresponding side of the first folding guide plate 221 are called the first side wings, and the side wings on the corresponding side of the second folding guide plate 222 are called the second side wings. The first side wings will overlap the second side wings after folding. Specifically, the first folding guide plate 221 includes a first torsion surface for folding the material side wing on the same side, and the second folding guide plate 222 includes a second torsion surface for folding the material side wing on the same side. The first torsion surface is located upstream of the second torsion surface, that is, the first torsion surface is partially (or entirely) positioned in front of the second torsion surface. When the material passes through, the first torsion surface of the first folding guide plate 221 first contacts the first side wing and gradually flips and folds it onto the upper surface of the material; subsequently, the second torsion surface of the second folding guide plate 222 flips and folds the second side wing, and stacks it on top of the first side wing. This sequential folding method can avoid mutual interference when both sides fold simultaneously.

[0033] See Figure 5 and Figure 6The multi-channel conveying mechanism includes an adsorption and transfer unit 41 and several horizontally arranged packaging connection channels 31. The outlet of the material conveying channel 21 is connected to the inlet of the packaging connection channel 31. The adsorption and transfer unit 41 is connected between the material conveying channel 21 and the packaging connection channel 31. The adsorption and transfer unit 41 is used to adsorb a certain amount of material from the material conveying channel 21, change the material from a longitudinal arrangement to a horizontal arrangement, and make the side wings folded by the rear folding guide plate 222 on the material face the entrance of the packaging connection channel 31. The adsorption and transfer unit 41 is used to pick up materials in groups on the suction and conveying channel 21 and transfer them to the corresponding packaging connection channel 31 of the multi-channel conveying unit 3. The adsorption and transfer unit 41 includes an adsorption component 411, a lifting and rotating bracket 412, and a following material picking drive component 413. The adsorption component 411 is disposed on the lifting and rotating bracket 412 and installed at the lower end of the lifting and rotating bracket 412. The lifting and rotating bracket 412 drives the material on the adsorption component 411 to rotate, changing the orientation of the folded material so that the second fold faces the entrance of the packaging connection channel 31. Specifically, the lifting and rotating bracket 412 includes a lifting base 4122 and a rotating mounting base 4121. The rotating mounting base 4121 is connected to a rotating power source that drives its rotation. A cylinder (or a motor) is fixedly disposed on the rotating mounting base 4121. The drive rod of the cylinder is connected to the lifting base 4122. Magnetic suction components are fixedly disposed at the lower end of the lifting base 4122. The number of magnetic suction components matches the number of packaging line connection channels. The following material-picking drive component 413 is connected to the lifting and rotating bracket 412 via a transmission connection. The following material-picking drive component 413 is electrically connected to the controller 9. The controller 9 controls the following material-picking drive component 413 to drive the adsorption component 411 to follow and pick up materials at a speed matching the material-picking and conveying channel 21. Specifically, a second material arrival sensor (which can be a photoelectric sensor or other sensor for detecting whether the material to be transferred is in place) is provided upstream of the adsorption and transfer unit 41. The controller 9 then controls the following material-picking drive component 413 to drive the magnetic suction component to move longitudinally synchronously with the material. Subsequently, the lifting base 4122 drives the magnetic suction component to move downwards to pick up the material, so that the material-picking and conveying channel 21 can continuously feed materials, improving production efficiency.

[0034] The adsorption component 411 can be a vacuum suction cup or a magnetic suction device. For products containing iron powder in the heating inner packaging of the material, the adsorption component 411 is preferably a magnetic suction device, which is a permanent magnet or electromagnet, installed at the lower end of the lifting and rotating bracket 412, and uses the iron powder in the heating inner packaging of the material for adsorption. The adsorption and transfer unit 41 also includes a feeding component 42, which includes a lifting feeding plate 421 and a pressing drive component. The lifting feeding plate 421 has a clearance notch 422 for the magnetic suction device to pass through. The pressing drive component drives the lifting feeding plate 421 to press the material on the magnetic suction device down into the packaging connection channel 31. The lifting feeding plate 421 has a lifting power source. The clearance notch 422 on the lifting feeding plate 421 allows the magnetic suction device to pass through, while the plate surface of the lifting feeding plate 421 presses the material off the magnetic suction device and into the packaging connection channel 31. The limiting component 32 of the packaging connection channel 31 prevents the side wings from rebounding and spreading out during the conveying process, ensuring that the shape is intact when entering the packaging process.

[0035] To ensure the material remains intact when it enters the packaging process, a limiting component 32 is provided on the upper side of the packaging connection channel 31. The limiting component 32 is used to prevent the side wings from springing back. The limiting component 32 can be a baffle. After the material is turned, with the second side wing facing the entrance of the packaging connection channel 31, the limiting component 32 can press down on the second side wing (the folded outer side wing), ensuring the material enters smoothly and preventing the side wings from springing back.

[0036] Due to manufacturing requirements, the heating inner package has dimensional tolerances. Therefore, a certain allowance is provided in the center of the heat-pressing process to accommodate these tolerances. This tolerance creates a gap between the side wings and the heating inner package, allowing the side wings to fold along this gap. Additionally, an adhesive layer is present in this gap to fix the side wings in their folded position. To achieve this fixed folding position along the gap, the side wing folding mechanism 2 further includes a shaping unit 6, located downstream of the folding wing unit 22. The shaping unit 6 includes a pressure roller 61 with elastic pressure. The pressure roller 61 is mounted on the frame 8 via a swing arm, and an elastic element 62 is connected to the swing arm, giving the pressure roller 61 elastic pressure. The pressure roller 61 rolls and shapes the material at the corresponding side wing folding positions. At least two pressure rollers 61 are provided, corresponding to the folding positions of the first and second side wings, respectively. The pressure rollers 61 align and roll along the side wing folding lines, shaping the side wings along the adhesive layer gap and further preventing subsequent side wing rebound.

[0037] To prevent defective products from entering subsequent packaging processes, they can be rejected before the side wings are folded. Specifically, the conveying plane 11 is formed by the outer surface of a telescopic conveyor belt. The inlet or outlet end of the telescopic conveyor belt is a telescopic end, and the frame 8 is provided with a defective product discharge port I, which is correspondingly located below the telescopic part. The inlet or outlet end of the telescopic conveyor belt is a telescopic section. When waste needs to be discharged, the telescopic section retracts, and the material loses its support and falls into the defective product discharge port I below, thus achieving defective product rejection. The detection of defective products and the telescopic conveyor belt are existing technologies, and their specific structures will not be described in detail here.

[0038] Additionally, waste can be removed after the material is folded on the side wings. The bottom of the suction conveyor channel 21 is equipped with a suction conveyor belt. The first folding guide plate 221 and the second folding guide plate 222 are located on both sides of the suction conveyor belt. The suction conveyor belt can fix the posture of the material during the side wing folding process, ensuring folding quality. There is a waste discharge gap between the suction conveyor belt and the multi-channel conveying unit 3. The frame 8 is equipped with a defective product waste discharge port II7 corresponding to the waste discharge gap. When defective material is detected, the adsorption and transfer unit 41 stops picking up material, and the suction conveyor belt allows the material to fall into the defective product waste discharge port II7 through the waste discharge gap. How to detect defective material is existing technology and will not be described further here.

[0039] The working principle of the preferred embodiment of the present invention is described below with reference to the accompanying drawings: The conveying plane 11 continuously moves multiple materials placed laterally at intervals forward. When the first material arrival sensor detects the arrival of the material, the controller 9 controls the longitudinal movement drive structure 1311 of the release paper waste removal drive unit 131 to drive the release paper waste removal unit 13 to move synchronously with the material according to the conveying speed of the conveying plane 11. During the synchronous movement, the positioning member 133 first presses down on both sides of the material for positioning, and then the lifting suction member 132 descends to absorb the release paper in the non-adhesive area, and then rises to peel off the release paper. The positioning member and the lifting suction member 132 rise to reset. After peeling is completed, the transverse movement drive structure 1312 drives the release paper waste removal unit 13 to move above the release paper waste discharge port 12, and the lifting suction member 132 blows air to discharge the waste paper into the release paper waste discharge port 12.

[0040] After the release paper is removed, the material enters the suction conveyor channel 21 and moves within it. During the movement, the first torsional surface of the first folding guide plate 221 of the folding wing unit 22 folds the first side wing, and then the second torsional surface of the second folding guide plate 222 folds the second side wing and overlaps it on top of the first side wing. The pressure roller 61 of the shaping unit 6 then rolls and shapes the folded side wing.

[0041] The folded material continues to move. After the second material arrival sensor detects the material, it sends a signal to the controller 9. The controller 9 controls the following material picking drive component 413 to drive the magnetic suction component to move synchronously with the material. The lifting and rotating bracket 412 drives the magnetic suction component to descend, picking up multiple materials at once. The rotating mounting base 4121 then drives the material to rotate, so that the second side wing faces the entrance of the packaging connection channel 31. Subsequently, the following material picking drive component 413 moves the rotated material to the top of the packaging connection channel 31. The lifting and unloading plate 421 then presses the folded material down into the corresponding packaging connection channel 31. The conveyor belt at the bottom of the packaging connection channel 31 transports the material. During the transport process, the limiting component 32 limits the side wing to prevent the side wing from rebounding. Example 2

[0042] The difference between this embodiment and Embodiment 1 lies in the specific structure of the release paper adsorption component 411.

[0043] In this embodiment, the release paper adsorption component 411 includes an upper adsorption conveyor belt, which is disposed between the release paper adsorption station and the release paper waste discharge station, and is located above the conveying plane 11. The upper adsorption conveyor belt is arranged in a ring between the release paper adsorption station and the release paper waste discharge station, and is inclined upward along the conveying direction of the conveying plane 11. The minimum gap between the conveying plane 11 and the upper adsorption conveyor belt is consistent with the material thickness.

[0044] During operation, the material is fed in through the conveyor plane 11. When it passes the release paper adsorption station, the lower surface of the upper adsorption conveyor belt adsorbs the release paper from the non-adhesive area. Because the upper adsorption conveyor belt is inclined upwards, the release paper is peeled off upwards and moved with the upper adsorption conveyor belt to the release paper waste discharge station for discharge. This non-reciprocating moving parts can continuously and efficiently complete the waste removal process.

[0045] The other structures and working methods are the same as in Example 1, and will not be described again here. Example 3

[0046] This embodiment is applicable to triplane materials, and adds a front wing folding mechanism 5 based on embodiment 1 or embodiment 2.

[0047] In this embodiment, a front wing folding mechanism 5 is provided between the conveying plane 11 and the suction conveying channel 21. The front wing folding mechanism 5 includes an air-blowing working surface 51 and a baffle plate 52. The air-blowing working surface 51 is used to blow air onto the front wing of the material and make it stand up. The baffle plate 52 is located downstream of the air-blowing working surface 51 and is used to fold the standing front wing downwards. The air-blowing plane is connected to the end of the conveying plane 11 and has an air-blowing hole 511 facing the front end of the material conveying direction. When the front wing of the material passes by, the air-blowing plane blows air upwards, making the front wing stand up vertically. As the material continues to move forward, the standing front wing touches the baffle plate 52 located downstream of the air-blowing plane. The folding guide surface of the baffle plate 52 causes the front wing to flip downwards and fold onto the upper surface of the material. To prevent the blowing action of the blowing plane from affecting the bonding posture, a pressure roller 53 can be installed at the end of the conveying plane 11. The pressure roller 53 is used to prevent the material being blown from shifting on the conveying plane 11. The pressure roller 53 is rotatably mounted on the frame 8 and cooperates with the conveying plane 11 to clamp and feed the material to ensure its conveying posture.

[0048] During operation, the pressure roller 53 and the conveying plane 11 work together to clamp and convey materials. The air blowing working surface 51 of the front wing folding mechanism 5 blows air onto the front wing to make it stand up. As the material continues to move forward, the standing front wing touches the downstream baffle plate 52. The folding guide surface of the baffle plate 52 causes the front wing to flip downward and fold onto the upper surface of the material. After the front wing is folded, the material enters the side wing folding mechanism 2 for the sequential folding of both sides.

[0049] The other structures and working methods are the same as in Embodiment 1 or Embodiment 2, and will not be described again here.
