[0015] The first and second rotating disks rotate synchronously, driving the first and second shafts of the same group to cycle through four designed positions in a circumferential direction. When the first and second shafts of the same group are in the loading position, they move closer together to clamp the label shaft. Then, the label shaft rotates with the first and second rotating disks to the winding position. The first and / or second shafts can rotate around their own axes, driving the label shaft to rotate synchronously, thus winding the label around the outside of the label shaft. The wound label shaft then rotates with the first and second rotating disks to the sealing position for sealing, and then rotates with the first and second rotating disks to the unloading position for unloading. The entire winding process uses a mechanical structure to ensure that the position of the label on the label shaft and the tightness of the winding remain consistent, thereby improving production efficiency and product quality.

[0016] The feeding assembly conveys the label shaft to the clamping structure located at the feeding position. After the clamping structure clamps the label shaft, the first shaft rotates circumferentially around its own axis, and the glue application assembly applies an adhesive layer to the outer surface of the label shaft. Then, it moves to the winding position, where the label adheres to the outside of the label shaft, and the first shaft rotates circumferentially around its own axis to wind the label into a label roll. Then, it moves to the sealing position, where the cutting assembly cuts the label at the winding position, and the first shaft rotates circumferentially around its own axis, and the sealing assembly seals the label to form a finished label roll. Then, it moves to the unloading position, where the receiving assembly recycles the finished label roll. The entire winding process uses a mechanical structure to ensure that the position of the label on the label shaft and the tightness of the winding remain consistent, thereby improving production efficiency and product quality.

[0041] This application is described in detail below. Examples of embodiments of this application are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. Furthermore, detailed descriptions of known technologies that are unnecessary for the features of this application are omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0042] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “the” used herein may also include the plural forms. It should be further understood that the term “comprising” as used in the specification of this application means the presence of the stated features, elements, and / or components, but does not exclude the presence or addition of one or more other features, elements, components, and / or groups thereof. The term “and / or” as used herein includes all or any units and all combinations thereof of one or more associated listed items.

[0043] like Figure 1-5 As shown, this application embodiment provides a label winding assembly, which mainly includes a base 1 and a shaft holder 2. The shaft holder 2 is installed on the base 1. The shaft holder 2 includes a first rotating disk 21 and a second rotating disk 22 that are coaxial and rotate synchronously in the circumferential direction, four first shafts 23 installed on the first rotating disk 21, and four second shafts 24 installed on the second rotating disk 22. The first shafts 23 and / or the second shafts 24 can rotate around their own axes. The four first shafts 23 and the four second shafts 24 correspond one-to-one to form four sets of clamping structures for clamping the label shaft. The label shaft is clamped between the first shafts 23 and the second shafts 24 in the same set. The first shafts 23 and the second shafts 24 in the same set can move relatively closer or further away in the axial direction. The four sets of clamping structures are cyclically stopped at four designed positions in the circumferential direction. The four designed positions are the feeding position, the winding position, the sealing position, and the unloading position.

[0044] In this embodiment, the first rotating disk 21 and the second rotating disk 22 are vertically arranged. The first shaft 23 passes through the first rotating disk 21, and the second shaft 24 passes through the second rotating disk 22. The first rotating disk 21 and the second rotating disk 22 rotate synchronously in a clockwise or counterclockwise direction to drive the first shaft 23 and the second shaft 24 to rotate synchronously and cyclically stop at four designed positions in the circumferential direction. The axes of the first shaft 23 and the second shaft 24 are horizontally arranged and coaxial. There is a gap between the first shaft 23 and the second shaft 24 in the same group for clamping the label shaft. This gap is adjusted by moving the first shaft 23 and the second shaft 24 closer or further apart to achieve clamping or lowering of the label shaft.

[0045] The feeding position, winding position, sealing position, and unloading position are evenly distributed circumferentially. The feeding position is located at the bottom, the winding position is located on the leftmost side and above the feeding position, the sealing position is located at the top and on the same vertical line as the feeding position, and the unloading position is on the rightmost side and above the feeding position and on the same horizontal line as the winding position.

[0046] The four clamping structures rotate clockwise. If the clamping structure starts from the loading position, it will move sequentially to the winding position, the sealing position, and the unloading position, then move from the unloading position to the loading position, and then move to the winding position to repeat the aforementioned cycle of movement and dwell.

[0047] The label winding assembly provided in this application embodiment features a first rotating disk 21 and a second rotating disk 22 that rotate synchronously, causing the first shaft 23 and the second shaft 24 of the same group to circumferentially cycle through four designed positions. When the first shaft 23 and the second shaft 24 of the same group are in the loading position, they move closer together to clamp the label shaft. Then, the label shaft rotates with the first rotating disk 21 and the second rotating disk 22 to the winding position. The first shaft 23 and / or the second shaft 24 can rotate around their own axis, causing the label shaft to rotate synchronously, thus winding the label around the outside of the label shaft. The wound label shaft then rotates with the first rotating disk 21 and the second rotating disk 22 to the sealing position for sealing, and then rotates with the first rotating disk 21 and the second rotating disk 22 to the unloading position for unloading. The entire winding process uses a mechanical structure to ensure that the position of the label on the label shaft and the tightness of the winding remain consistent, thereby improving production efficiency and product quality.

[0048] like Figure 1-7As shown, in one optional implementation, the first shaft 23 includes an outer shaft 231 and an inner shaft 232. The outer shaft 231 and the inner shaft 232 can move relative to each other or closer along the axial direction; the first end of the inner shaft 232 is away from the second shaft 24, and the second end of the inner shaft 232 is close to the second shaft 24 and forms a cylindrical limiting seat 2321. The diameter of the limiting seat 2321 is larger than the shaft diameter of the inner shaft 232. The limiting seat 2321 protrudes axially on the side close to the second shaft 24 to form a limiting boss 2322. The limiting boss 2322 is centrally located. Multiple guide holes 2323 are provided around the outside of the limiting boss 2322; the label shaft is sleeved on the outside of the limiting boss 2322; the first end of the outer shaft 231 is far away from the second shaft 24, and the second end of the outer shaft 231 is close to the second shaft 24 and forms multiple guide posts 2311. The guide posts 2311 extend toward the second shaft 24, and the multiple guide posts 2311 and the multiple guide holes 2323 correspond one to one. The guide posts 2311 are provided in the guide holes 2323.

[0049] Based on the aforementioned embodiments, in this embodiment, the outer shaft 231 has a hollow structure and is sleeved on the outside of the inner shaft 232 and coaxial. At least one of the outer shaft 231 and the inner shaft 232 can move relatively away from or closer to each other along the axial direction under the action of an external force, so as to adjust the relative position of the outer shaft 231 and the inner shaft 232.

[0050] The inner shaft 232 includes a shaft body and a limiting seat 2321 coaxially connected, the diameter of which is larger than that of the shaft body. A limiting boss 2322 is formed at the center of the limiting seat 2321, protruding from the side of the limiting seat 2321 near the second shaft 24. The label shaft has a hollow structure, and one end of the label shaft is sleeved on the outside of the limiting boss 2322 to ensure the stability of the label shaft. The limiting seat 2321 has multiple guide holes 2323 along its own axial direction, which are evenly distributed around the outside of the limiting boss 2322 in the circumferential direction.

[0051] The outer shaft 231 includes a hollow shaft body 2312 and multiple guide posts 2311 connected to it. The hollow shaft body 2312 has segments with different outer diameters to adapt to different components. The axis of the guide posts 2311 is parallel to the axis of the hollow shaft body 2312. The multiple guide posts 2311 are evenly distributed circumferentially, and the shapes of the guide posts 2311 and the guide through holes 2323 are adapted to each other. The guide posts 2311 are inserted into the guide through holes 2323 and slide along the guide through holes 2323 to ensure that the outer shaft 231 and the inner shaft 232 can move relatively away from or towards each other axially.

[0052] like Figure 1-7As shown, in an optional implementation, the first shaft 23 further includes a first elastic member 233; the inner wall of the second end of the outer shaft 231 forms an inwardly protruding support platform; the first elastic member 233 is clamped between the limiting seat 2321 and the support platform; and a plurality of guide posts 2311 surround the outer side of the elastic member in the circumferential direction.

[0053] Based on the aforementioned embodiments, in this embodiment, the support platform is annular and formed inside the hollow shaft 2312, away from the guide post 2311. The first elastic element 233 is a spring, one end of which abuts against the support platform, and the other end abuts against the side of the limiting seat 2321 opposite to the second shaft 24. The inner shaft 232 moves axially towards the first end of the outer shaft 231, the distance between the limiting seat 2321 and the support platform decreases, and the first elastic element 233 compresses and accumulates elastic potential energy; the inner shaft 232 moves axially towards the second end of the outer shaft 231, the distance between the limiting seat 2321 and the support platform increases, and the first elastic element 233 releases the compressed and accumulated elastic potential energy, causing the inner shaft 232 to reset.

[0054] like Figure 1-5 As shown, in one optional embodiment, the base 1 includes a cam divider 11, a turntable flange shaft 12, a fixing plate 13, and two shaft drive members 14; the turntable flange shaft 12 is driven to rotate around its own axis by being connected to the output shaft of the cam divider 11; the fixing plate 13 is sleeved on the outside of the turntable flange shaft 12 via a bearing seat; a first rotating disk 21 and a second rotating disk 22 are spaced apart and sleeved on the outside of the turntable flange shaft 12; along the axial direction of the turntable flange shaft 12, the second rotating disk 22, the first rotating disk 21, the fixing plate 13, and the cam divider 11 are arranged sequentially; two A shaft drive 14 is fixed to a fixed plate 13, and the output shaft of the shaft drive 14 faces the first rotating disk 21. The first shaft drive 14 corresponds to the loading position, and the output end of the first shaft drive 14 is detachably connected to the first shaft 23 located at the loading position to drive the first shaft 23 to move axially closer to or away from the second shaft 24. The second shaft drive 14 corresponds to the unloading position, and the output end of the second shaft drive 14 is detachably connected to the first shaft 23 located at the unloading position to drive the first shaft 23 to move axially closer to or away from the second shaft 24.

[0055] Based on the aforementioned embodiments, in this embodiment, the cam divider 11 drives the first rotating disk 21 and the second rotating disk 22 to rotate synchronously via the turntable flange shaft 12, while the fixed plate 13 remains stationary relative to the cam divider 11. Both shaft drive members 14 are fixed to the side of the fixed plate 13 opposite to the first rotating disk 21, and the output shaft of the shaft drive member 14 passes through the fixed plate 13. The output shaft of the shaft drive member 14 is connected to the inner shaft 232 of the first shaft 23 and drives the inner shaft 232 to move along its own axial direction, thereby enabling the inner shaft 232 to move between a clamping position and a releasing position. When the inner shaft 232 is in the clamping position, the distance between the inner shaft 232 and the second shaft 24 is small, and the label shaft can be clamped between the first shaft 23 and the second shaft 24; when the inner shaft 232 is in the releasing position, the distance between the inner shaft 232 and the second shaft 24 is large, and the label shaft can be separated from both the first shaft 23 and the second shaft 24. More specifically, the first axis drive 14 drives the inner shaft 232 to move toward the second axis 24; the second axis drive 14 drives the inner shaft 232 to move away from the second axis 24.

[0056] like Figure 1-10 As shown, in an optional embodiment, the shaft holder 2 further includes a pull head 25, which is elongated and connected to the end of the first shaft 23 away from the second shaft 24. The pull head 25 includes a first limiting plate, a connecting section, and a second limiting plate connected in sequence. In the axial direction of the connecting section, the projections of the first limiting plate and the second limiting plate both cover the projection of the connecting section. The output shaft of the shaft drive 14 is connected to the connecting groove 15, the bottom of which faces the pull head 25. The first end of the connecting groove 15 serves as the inlet end and forms a first notch 151. The first notch 151 is formed in the connecting section. The first groove wall 152 of the connecting groove 15 is recessed in a direction away from the second groove wall 154 of the connecting groove 15, and the first groove wall 152 forms a first edge 153 extending toward the second groove wall 154; the first groove wall 152 and the second groove wall 154 of the connecting groove 15 are opposite to each other; the second end of the connecting groove 15 serves as the outlet end and forms a second notch 155, which is formed in the second groove wall 154 of the connecting groove 15, and the second notch 155 is recessed in a direction away from the first groove wall 152 of the connecting groove 15, and the second groove wall 154 forms a second edge 156 extending toward the second groove wall 154.

[0057] Based on the foregoing embodiments, in this embodiment, the slider 25 further includes a connecting portion disposed on the side of the first limiting plate opposite to the connecting section. The connecting portion is used to connect to the end of the first shaft 23 away from the second shaft 24. The first and second limiting plates are arranged parallel to each other, and the connecting section is perpendicular to both the first and second limiting plates. The connecting section is cylindrical. The first and second limiting plates protrude radially outward from the connecting section. The second limiting plate is away from the first shaft 23.

[0058] The first shaft drive member 14 has a vertically extending connecting groove 15. The first groove wall 152 is on the right, and the second groove wall 154 is on the left. The upper end of the connecting groove 15 of the first shaft drive member 14 serves as the first end, i.e., the inlet end, with the first notch 151 recessed to the right. The lower end of the connecting groove 15 of the first shaft drive member 14 serves as the second end, i.e., the outlet end, with the second notch 155 recessed to the left. The first edge 153 and the second edge 156 extend towards each other and are disposed on the same plane. The first edge 153 and the second edge 156 are not connected, and both the first edge 153 and the second edge 156 are disposed away from the bottom of the groove.

[0059] The extension direction of the connecting groove 15 of the second shaft drive member 14 is horizontal, with the first groove wall 152 on top and the second groove wall 154 on the bottom. The left end of the connecting groove 15 of the first shaft drive member 14 is the first end, that is, the inlet end, and the first notch 151 is recessed upward. The lower end of the connecting groove 15 of the second shaft drive member 14 is the second section, that is, the outlet end, and the second notch 155 is recessed downward.

[0060] The pull head 25 moves with the first shaft 23 from the unloading position to the loading position, that is, it moves circumferentially from right to left and downward. The first notch 151 and the second notch 155 of the connecting groove 15 of the first shaft drive member 14 are correspondingly arranged from right to left and downward. Part of the pull head 25 and the second limiting plate enter the connecting groove 15 through the first notch 151. The first shaft drive member 14 drives the connecting groove 15 to move towards the second shaft 24. The first edge 153 and the second edge 156 push the first limiting plate and thus push the inner shaft 232 to move towards the second shaft 24, that is, towards the clamping position. The pull head 25 moves with the first shaft 23 from the loading position to the winding position, that is, it moves circumferentially from bottom to left and upward. Part of the pull head 25 and the second limiting plate located in the connecting groove 15 move out of the connecting groove 15 through the second notch 155.

[0061] The pull head 25 moves from the sealing position to the unloading position along the first shaft 23, that is, it moves circumferentially from top to bottom right. The first notch 151 and the second notch 155 of the connecting groove 15 of the second shaft drive member 14 are correspondingly set from top to bottom right. Part of the pull head 25 and the second limiting plate enter the connecting groove 15 through the first notch 151. The first shaft drive member 14 drives the connecting groove 15 to move away from the second shaft 24. The first edge 153 and the second edge 156 push the second limiting plate, which in turn pushes the inner shaft 232 away from the second shaft 24, that is, it moves towards the shaft release position. The pull head 25 moves from the unloading position to the loading position along the first shaft 23, that is, it moves circumferentially from right to bottom left. Part of the pull head 25 and the second limiting plate located in the connecting groove 15 move out of the connecting groove 15 through the second notch 155.

[0062] like Figure 1-5As shown, in an optional embodiment, the base 1 further includes three drive components 16, which are respectively located near the feeding position, the winding position, and the sealing position. Each drive component 16 includes a motor 161, a drive gear 162, a driven gear 163, a swing arm 164, and a second elastic element 165. The motor 161 is fixed to the fixing plate 13, the drive gear 162 is sleeved on the outside of the output shaft of the motor 161, the swing arm 164 is sleeved on the outside of the output shaft of the motor 161 through a bearing seat, the driven gear 163 is fixed to the first end of the swing arm 164 and meshes with the drive gear 162, and the driven gear 163 is used to drive the first shaft 23 so that the first shaft 23 can rotate around its own axis. The second elastic element 165 is connected to the second end of the swing arm 164.

[0063] Based on the aforementioned embodiments, in this embodiment, the drive assembly 16 provides power for the first shaft 23 to rotate circumferentially around its own axis. When the first shaft 23 rotates circumferentially to the feeding position, winding position, or sealing position, it meshes with the driven gear 163 near the corresponding position, and the motor 161 drives the first shaft 23 to rotate around its axis.

[0064] The swing arm 164 provides space for the connection and separation of the drive gear 26 and the driven gear 163. The elastic element is used to reset the swing arm 164 to avoid the problem that the two turntables cannot rotate due to the meshing of the drive gear 26 and the driven gear 163.

[0065] like Figure 1-5 As shown in Figure 9, as an optional embodiment, the shaft holder 2 further includes a transmission gear 26, which is sleeved on the outside of the first shaft 23 and disposed between the first rotating disk 21 and the fixed plate 13. The transmission gear 26 is meshed with the driven gear 163.

[0066] Based on the aforementioned embodiments, in this embodiment, the transmission gear 26 is sleeved on the outside of the outer shaft 231, the motor 161 drives the outer shaft 231 to rotate, and the outer shaft 231 drives the inner shaft 232 to rotate synchronously through the guide through hole 2323 and the guide post 2311.

[0067] like Figure 1-5 As shown, as an optional implementation, the second shaft 24 passes through the second rotating disk 22, and the second shaft 24 can move closer to or further away from the first shaft 23 along its own axial direction.

[0068] Based on the aforementioned embodiments, in this embodiment, the second shaft 24 includes a first sub-shaft and a second sub-shaft connected together. The first sub-shaft is threaded through the second rotating disk 22, and the second sub-shaft is close to the first shaft 23. The distance between the second sub-shaft and the first shaft 23 can be adjusted by rotating the first sub-shaft to accommodate label shafts of different lengths.

[0069] like Figure 11 and12 As shown, based on the same inventive concept, this application provides a label winding device, which mainly includes a label winding assembly, a feeding assembly 3, a cutting assembly 5, a sealing assembly 6, and a receiving assembly 7 as described in any of the foregoing embodiments; the feeding assembly 3 is disposed on the first side of the winding assembly and near the feeding position; the adhesive application assembly 4 is disposed on the second side of the winding assembly and near the feeding position, and is used to apply adhesive for adhering the label to the outside of the label shaft; the cutting assembly 5 is disposed on the third side of the winding assembly and near the winding position; the label shaft winds the label at the winding position to form a label roll, and the cutting assembly 5 is used to cut the label of the label roll after the label roll moves to the sealing position with the shaft holder 2; the sealing assembly 6 is disposed on the fourth side of the winding assembly and near the sealing position, and is used to seal the label roll of the cut label; the receiving assembly 7 is disposed on the fifth side of the winding assembly and near the unloading position.

[0070] Based on the foregoing embodiments, in this embodiment, the label winding device is installed in an equipment cabinet. The feeding component 3 is located below the winding component, the gluing component 4 is located at the lower right of the winding component, the cutting component 5 is located on the left side of the winding component, the sealing component 6 is located above the winding component, and the receiving component 7 is located on the right side of the winding component.

[0071] The label winding device provided in this application embodiment delivers the label shaft to the clamping structure located at the feeding position. After the clamping structure clamps the label shaft, the first shaft 23 rotates circumferentially around its own axis, and the glue application component 4 coats the outer surface of the label shaft to form an adhesive layer. Then, it moves to the winding position, where the label adheres to the outside of the label shaft, and the first shaft 23 rotates circumferentially around its own axis to form a label roll. Then, it moves to the sealing position, where the cutting component 5 cuts the label located at the winding position, and the first shaft 23 rotates circumferentially around its own axis, and the sealing component 6 seals the label to form a finished label roll. Then, it moves to the unloading position, where the receiving component 7 recycles the finished label roll. The entire winding process uses a mechanical structure to ensure that the position of the label on the label shaft and the tightness of the winding remain consistent, thereby improving production efficiency and product quality.

[0072] In some embodiments, the adhesive application assembly 4 includes a first driving device and a coating roller connected by a drive; the first driving device drives the adhesive application roller to move closer to or away from the loading position; when the coating roller is close to the loading position, it is used to apply adhesive to the label shaft.

[0073] Based on the aforementioned embodiments, in this embodiment, after the clamping structure clamps the label shaft at the loading position, the first driving device drives the coating roller to move upwards towards the label shaft. The label shaft rotates synchronously under the influence of the first shaft 23 rotating around its own axis, and the coating roller applies double-sided adhesive to the outside of the label shaft. After the adhesive application is complete, the first driving device drives the coating roller to move downwards away from the loading position.

[0074] In some embodiments, the feeding assembly 3 includes a second driving device and a conveying structure connected by a drive; the first driving device drives the conveying structure to move closer to or away from the feeding position, the conveying structure is used to feed the shaft holding member 2 when it is close to the feeding position, and the conveying structure is used to receive material when it is away from the feeding position.

[0075] Based on the aforementioned embodiments, in this embodiment, the material handling structure includes a feeding gripper and a weight sensor connected to each other. After the label shaft moves to the feeding gripper, the weight sensor senses the weight of the label shaft. The first shaft 23 moves backward, that is, moves away from the second shaft 24. There is a large gap between the limiting boss 2322 and the second shaft 24. The second driving device drives the feeding gripper to move upward and closer to the feeding position, moving the label shaft to the aforementioned large gap. The first shaft 23 moves forward, that is, moves closer to the second shaft 24. The limiting boss 2322 extends into the hollow structure of the label shaft, and the second shaft 24 abuts against the label shaft to clamp and fix the label shaft.

[0076] In some embodiments, the sealing assembly 6 includes a third driving device and a roller connected by a drive, the third driving device driving the roller to approach the sealing position to press against the label roll; and a fourth driving device and an adhesive component connected by a drive, the fourth driving device driving the adhesive component to approach the sealing position to adhere to the label on the label roll.

[0077] Based on the aforementioned embodiments, in this embodiment, after the clamping structure with the label shaft moves to the sealing position, the third driving device drives the roller to move downward and press the label roll. The fourth driving device drives the adhesive component to move downward and adhere to the outside of the label on the label roll. The first shaft 23, located at the sealing position, rotates around its own axis to further wind the label, thereby applying single-sided adhesive to the outside of the label on the label roll. The roller presses the label with the single-sided adhesive, thus sealing the label roll.

[0078] In some embodiments, the receiving assembly 7 includes a fifth driving device and a receiving trough that are driven together; the fifth driving device drives the receiving trough to move between a receiving position and a waiting position; when the receiving trough is in the receiving position, the inlet end of the receiving trough is close to the sealing position and the outlet end of the receiving trough is far from the sealing position; when the receiving trough is in the waiting position, both the inlet end and the outlet end of the receiving trough are far from the sealing position.

[0079] Based on the aforementioned embodiments, in this embodiment, after the clamping structure with the label roll moves to the unloading position, the fifth driving device drives the receiving trough to move upward and approach the sealing position. The first shaft 23 located at the sealing position moves backward, and the label roll separates from the shaft holder 2 and falls into the receiving trough. The receiving trough tilts downward, and the label roll rolls along the receiving trough to achieve material collection.

[0080] As an optional implementation, the label winding device also includes a circular vibratory plate 8 and a linear vibrator 9; the output end of the circular vibratory plate 8 is connected to the input end of the linear vibrator 9, and the output end of the linear vibrator 9 corresponds to the input end of the feeding assembly 3, for transporting the label shaft to be wound.

[0081] Based on the aforementioned embodiments, in this embodiment, the label shaft is vibrated out of the circular vibratory feeder 8 and enters the linear vibrator 9 in the same direction. After the sensor on the linear vibrator 9 senses the label shaft material vibrated out of the circular vibratory feeder 8, the linear vibrator 9 starts to operate, conveying the label shaft to the feeding assembly 3. The output end of the linear vibrator 9 corresponds to the input end of the feeding assembly 3. The label shaft to be wound moves from the circular vibratory feeder 8 to the linear vibrator 9, and then from the linear vibrator 9 to the feeding assembly 3.

[0082] In one specific embodiment, the circular vibratory feeder 8 and the linear vibrator 9 deliver the label shaft to the feeding position of the winding mechanism. After the feeding hand sensor connected to the lifting cylinder detects the material, the first shaft 23 at the feeding position retracts. After receiving the signal, the lifting cylinder lifts the label shaft. After reaching the position, the first shaft 23 extends and fixes the label shaft between the first shaft 23 and the second shaft 24. The lifting cylinder resets, and the adhesive application assembly 4 moves upward after receiving the instruction. The double-sided adhesive is pressed onto the label shaft by the adhesive roller. After the double-sided adhesive is stuck on the label shaft, the first shaft 23 rotates, causing the label shaft to rotate synchronously. After the double-sided adhesive has covered the label shaft once, the cylinder of the adhesive application assembly 4 starts to cut the double-sided adhesive, and then the adhesive application assembly 4 resets.

[0083] The first rotating disk 21 and the second rotating disk 22 rotate clockwise, moving the clamping structure with the label shaft to the winding position. During the first winding of the label, the label needs to be manually attached to the double-sided tape on the label shaft beforehand. The first shaft 23 rotates for a set number of turns and then stops, so that the label is wound on the label shaft into a label roll of a specified size, and then rotates to the sealing position.

[0084] The label roll rotates to the sealing position and is sealed with single-sided adhesive tape; otherwise, the label roll will fall off. After receiving the instruction, the sealing component 6 extends the pressure plate cylinder with the adhesive-coated roller, causing the adhesive-coated roller to press against the ribbon, i.e., the label. At this time, the shearing component at the winding position receives the instruction and begins to operate, cutting the label. Subsequently, the first shaft 23 at the sealing position rotates, driving the cut label to slowly rewind. The sealing component 6 adheres the single-sided adhesive tape to the cut ribbon, and the adhesive-coated roller and the first shaft 23 on it continue to rotate, achieving single-sided sealing. The sealing component 6 then resets and rotates to the unloading position to complete the material collection.
