Description

Technical Field

[0001] This application relates to the field of battery manufacturing equipment technology, specifically a winding device and a winding machine. Background Technology

[0002] In the lithium battery manufacturing process, the strips (such as cathode sheets, separators, and anode sheets) unwound from the unwinding device need to be wound to form battery cells.

[0003] The unwinding device includes an unwinding shaft for mounting the material roll, which drives the roll to rotate and unwind the output strip. Because it only includes one unwinding shaft, the downtime during roll changes is relatively long. Alternatively, an unwinding device with an automatic roll-changing function can be used. This device includes two unwinding shafts that can alternately serve as a working shaft and a spare shaft; one shaft acts as the working shaft for unwinding, while the other acts as a spare shaft for preparing materials (unloading empty rolls and loading full rolls). During roll changes, manual unloading of empty rolls from the unwinding shaft and loading of full rolls onto it is required, resulting in low automation, high labor intensity, and low production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a winding device and winding machine that can improve automation, reduce manual labor intensity, and increase production efficiency to address the above problems.

[0005] A roll changing device, comprising:

[0006] The unwinding mechanism includes an unwinding shaft, a first pusher, and a first drive member. The first pusher is movably arranged along the axial direction of the unwinding shaft and is connected to the drive end of the first drive member.

[0007] A material storage mechanism includes a material storage shaft, a second pusher, and a second drive member. The second pusher is movably disposed along the axial direction of the material storage shaft and is connected to the drive end of the second drive member.

[0008] A transfer mechanism includes a drive assembly and a transfer component disposed at the drive end of the drive assembly. The transfer component includes a transfer shaft, a third pusher, and a third drive member. The third pusher is movably disposed along the axial direction of the transfer shaft and is connected to the drive end of the third drive member.

[0009] In some embodiments, under the driving action of the drive component, the transfer component can move to the point where the transfer shaft is axially aligned with the unwinding shaft or the storage shaft.

[0010] In some embodiments, the unwinding mechanism further includes a first mounting base and a first guide rod. The first mounting base has a first guide hole, the first guide rod passes through the first guide hole, and the first pusher is connected to one end of the first guide rod.

[0011] In some embodiments, the storage shaft has a cavity and a clearance groove communicating with the cavity, the clearance groove extending longitudinally along the axial direction of the storage shaft;

[0012] The storage mechanism further includes a transmission unit disposed in the cavity of the storage shaft. The input end of the transmission unit is connected to the driving end of the second driving member, and the output end of the transmission unit passes through the clearance groove and is connected to the second pushing member.

[0013] In some embodiments, the transmission unit includes a lead screw and a moving member. The lead screw is rotatably connected to the cavity of the storage shaft, and the axial direction of the lead screw is aligned with the axial direction of the storage shaft. The output shaft of the second drive member is connected to the lead screw. The moving member is threaded onto the lead screw, passes through the clearance groove, and is connected to the second pusher member.

[0014] In some embodiments, the storage mechanism further includes a second mounting base and a moving drive component. The storage shaft and the second drive component are both mounted on the second mounting base. The second mounting base is mounted on the driving end of the moving drive component, and the moving drive component is used to drive the second mounting base to move axially along the storage shaft.

[0015] In some embodiments, the transfer assembly further includes a third mounting base and a second guide rod. The third mounting base is connected to the drive end of the drive assembly and has a second guide hole. The second guide rod passes through the second guide hole, and the third pusher is connected to one end of the second guide rod.

[0016] In some embodiments, the roll changing device further includes a waste shaft, and under the driving action of the drive assembly, the transfer assembly can also move to the point where the transfer shaft is axially aligned with the waste shaft.

[0017] In some embodiments, the unwinding shaft, the waste shaft, and the storage shaft are arranged at intervals along a first direction, and the axial directions of the unwinding shaft, the waste shaft, the storage shaft, and the transfer shaft are all parallel to a second direction, while the first direction is perpendicular to the second direction.

[0018] In some embodiments, one end of the storage shaft that is axially connected to the transfer shaft is the inlet / outlet end, and the second pusher is provided with a pusher block on the side facing the inlet / outlet end.

[0019] In some embodiments, the roll changing device further includes a starting mechanism connected to the drive end of the drive assembly. The starting mechanism includes a clamping drive, a first clamp, and a second clamp. The first clamp and the second clamp are arranged opposite to each other, and at least one of them is connected to the drive end of the clamping drive. The second clamp has adsorption surfaces on both opposite sides.

[0020] In some embodiments, the starting mechanism can abut against the roll using either of the adsorption surfaces to bond the tape on the adsorption surface to the starting end of the tape on the roll.

[0021] In some embodiments, the first clamping member has a first guide surface and a second guide surface on the side opposite to the second clamping member, and the arrangement direction of the first guide surface and the second guide surface is consistent with the arrangement direction of the two adsorption surfaces.

[0022] In the direction from the first clamping member to the second clamping member, the distance between the first guide surface and the second guide surface gradually increases.

[0023] In some embodiments, the roll changing device further includes a smoothing mechanism, which includes a mounting base and a first smoothing member and a second smoothing member, both mounted on the mounting base, with a smoothing channel formed between the first smoothing member and the second smoothing member.

[0024] In some embodiments, the first smoothing member and the second smoothing member are respectively capable of abutting against the two adsorption surfaces of the second clamping member entering the smoothing channel.

[0025] A winding machine includes a winding device as described in any of the above embodiments.

[0026] In actual use, after the material roll on the unwinding shaft is unwound, the drive assembly drives the transfer assembly to move toward the unwinding shaft until the transfer shaft axially aligns with the unwinding shaft. At this time, the first drive unit drives the first pusher to move axially along the unwinding shaft, thereby pushing the material roll on the unwinding shaft toward the transfer shaft until the material roll on the unwinding shaft is pushed onto the transfer shaft. Then, the drive assembly drives the transfer assembly to move to a designated position, and the third drive unit drives the third pusher to move axially along the transfer shaft until the material roll on the transfer shaft is pushed away from the transfer shaft, thereby realizing the unloading of the material roll. Then, the drive assembly drives the transfer assembly to move toward the storage mechanism until the transfer shaft axially aligns with the storage shaft. At this time, the second drive unit drives the second pusher to move axially along the storage shaft, thereby pushing the material roll on the storage shaft toward the transfer shaft until the material roll on the storage shaft moves onto the transfer shaft. Then, the drive assembly drives the transfer assembly to move toward the unwinding mechanism until the transfer shaft axially aligns with the unwinding shaft. At this time, the third driving component drives the third pushing component to move axially along the transfer shaft, thereby pushing the material roll on the transfer shaft toward the unwinding shaft until the material roll on the transfer shaft moves onto the unwinding shaft.

[0027] Thus, the aforementioned roll changing device automatically unloads the material cylinder on the unwinding shaft of the unwinding mechanism and automatically feeds the material roll from the storage shaft to the unwinding shaft through the transfer mechanism. This eliminates the need for manual unloading of the material cylinder and feeding of the material roll, thereby improving the automation level of the roll changing device, greatly reducing the labor intensity of workers, and increasing production efficiency.

[0042] Please see Figure 1 This application provides a winding changing device, including an unwinding mechanism 10, a material storage mechanism 20, and a transfer mechanism 30. The unwinding mechanism 10 includes an unwinding shaft 11, a first pusher 12, and a first drive member 13 (see...). Figure 2 The unwinding shaft 11 is used to load the material roll and can drive the material roll on it to rotate, thereby unwinding and outputting the material strip downstream. The first pusher 12 is movably arranged along the axial direction of the unwinding shaft 11 and is connected to the drive end of the first drive member 13. The first drive member 13 is used to drive the first pusher 12 to move along the axial direction of the unwinding shaft 11, thereby pushing the material roll on the unwinding shaft 11 away from the unwinding shaft 11. It should be noted that the material roll includes the material roll and the material strip wound on the material roll. Therefore, after the material roll on the unwinding shaft 11 is unwound, the first pusher 12 is needed to push the material roll on the unwinding shaft 11 away from the unwinding shaft 11 so that a new material roll can be loaded onto the unwinding shaft 11.

[0043] The storage mechanism 20 includes a storage shaft 21, a second pusher 22, and a second drive 23 (see...). Figure 3 The storage shaft 21 is used to load material rolls. A second pusher 22 is movably disposed along the axial direction of the storage shaft 21 and connected to the drive end of a second drive member 23. The second drive member 23 drives the second pusher 22 to move axially along the storage shaft 21, thereby pushing the material rolls on the storage shaft 21 away from the storage shaft 21. The transfer mechanism 30 includes a drive assembly 33 and a transfer assembly 31 disposed at the drive end of the drive assembly 33, the drive assembly 33 driving the transfer assembly 31 to move. Please refer to [further details omitted]. Figure 4As shown, the transfer assembly 31 includes a transfer shaft 311, a third pusher 312, and a third drive 313. The third pusher 312 is movably disposed along the axial direction of the transfer shaft 311 and is connected to the drive end of the third drive 313. The third drive 313 is used to drive the third pusher 312 to move along the axial direction of the transfer shaft 311 to push the material roll or cylinder on the transfer shaft 311 away from the transfer shaft 311. The drive assembly 33 can drive the transfer assembly 31 to a position where the transfer shaft 311 is axially aligned with the unwinding shaft 11, and the drive assembly 33 can also drive the transfer assembly 31 to a position where the transfer shaft 311 is axially aligned with the storage shaft 21.

[0044] In actual use, after the unwinding roll on the unwinding shaft 11 is unwound, the drive assembly 33 drives the transfer assembly 31 to move toward the unwinding shaft 11 until the transfer shaft 311 is axially aligned with the unwinding shaft 11. At this time, the first drive member 13 drives the first pusher 12 to move axially along the unwinding shaft 11, thereby pushing the material cylinder on the unwinding shaft 11 toward the transfer shaft 311 until the material cylinder on the unwinding shaft 11 is pushed onto the transfer shaft 311. Then, the drive assembly 33 drives the transfer assembly 31 to move to a designated position, and the third drive member 313 drives the third pusher 312 to move axially along the transfer shaft 311 until the material cylinder on the transfer shaft 311 is pushed away from the transfer shaft 311, thereby realizing the unloading of the material cylinder. Then, the drive assembly 33 drives the transfer assembly 31 to move toward the storage mechanism 20 until the transfer shaft 311 is axially aligned with the storage shaft 21. At this time, the second drive member 23 drives the second pusher member 22 to move axially along the storage shaft 21, thereby pushing the material roll on the storage shaft 21 toward the transfer shaft 311 until the material roll on the storage shaft 21 moves onto the transfer shaft 311. Then, the drive assembly 33 drives the transfer assembly 31 to move toward the unwinding mechanism 10 until the transfer shaft 311 is axially aligned with the unwinding shaft 11. At this time, the third drive member 313 drives the third pusher member 312 to move axially along the transfer shaft 311, thereby pushing the material roll on the transfer shaft 311 toward the unwinding shaft 11 until the material roll on the transfer shaft 311 moves onto the unwinding shaft 11.

[0045] Thus, the aforementioned roll changing device automatically unloads the material cylinder on the unwinding shaft 11 of the unwinding mechanism 10 and automatically feeds the material roll on the storage shaft 21 onto the unwinding shaft 11 through the transfer mechanism 30. This eliminates the need for manual unloading of the material cylinder and feeding of the material roll, thereby improving the automation level of the roll changing device, greatly reducing the labor intensity of workers, and increasing production efficiency.

[0046] Furthermore, the rewinding device also includes a waste shaft 40 for loading the material cylinder. The drive assembly 33 can also drive the transfer assembly 31 to move to a position where the transfer shaft 311 is axially aligned with the waste shaft 40. Thus, after the material cylinder on the unwinding shaft 11 is pushed onto the transfer shaft 311 of the transfer assembly 31, the drive assembly 33 drives the transfer assembly 31 to move toward the waste shaft 40 until the transfer shaft 311 is axially aligned with the waste shaft 40. At this time, the third drive member 313 drives the third pusher member 312 to move axially along the transfer shaft 311, thereby pushing the material cylinder on the transfer shaft 311 toward the waste shaft 40 until the material cylinder on the transfer shaft 311 moves onto the waste shaft 40, thus realizing the unloading of the material cylinder.

[0047] Optionally, the unwinding shaft 11, the scrap shaft 40, and the storage shaft 21 are arranged at intervals along the first direction X. The axial directions of the unwinding shaft 11, the scrap shaft 40, the storage shaft 21, and the transfer shaft 311 are all perpendicular to the second direction Y (see...). Figure 2 The first direction X is parallel to the second direction Y. The drive assembly 33 can drive the transfer assembly 31 to move along the first direction X, so that the transfer shaft 311 of the transfer assembly 31 can pass through the unwinding shaft 11, the waste shaft 40 and the storage shaft 21, which helps to simplify the stroke of the transfer assembly 31 and improve production efficiency.

[0048] It should be noted that the unwinding shaft 11, the waste shaft 40 and the storage shaft 21 are not limited to being arranged at intervals along the first direction X. Other arrangements can also be used in other embodiments, as long as the transfer of the material cylinder and the material roll can be achieved. No limitation is made here.

[0049] Please see Figure 1 and Figure 2 In the embodiments of this application, the unwinding mechanism 10 further includes a first mounting base 14, a first guide rod 15, and a first limiting member 16. A first guide hole is provided on the first mounting base 14, and the first guide rod 15 passes through the first guide hole on the first mounting base 14 and is slidable along the first guide hole. A first pusher 12 is connected to one end of the first guide rod 15, and the first limiting member 16 is connected to the other end of the first guide rod 15. A first drive member 13 is mounted on the first mounting base 14, and the drive end of the first drive member 13 is connected to the first pusher 12. Thus, the first guide rod 15 guides the axial movement of the first pusher 12 along the unwinding shaft 11, and the first limiting member 16 limits the maximum stroke of the first pusher 12, preventing the first guide rod 15 from dislodging from the first guide hole. Optionally, the first drive member 13 can be a cylinder.

[0050] Furthermore, the first mounting base 14 has two first guide holes, and two first guide rods 15 are also provided. The two first guide rods 15 pass through the two first guide holes respectively, the first pusher 12 is connected to the same end of the two first guide rods 15, and the first limiting member 16 is connected to the other end of the two first guide rods 15. In this way, the two first guide rods 15 simultaneously guide the first pusher 12, making the pushing action of the first pusher 12 more stable and reliable.

[0051] Furthermore, the unwinding shaft 11 can rotate around its own axis and can also move axially along the unwinding shaft 11. Thus, by controlling the rotation of the unwinding shaft 11 around its own axis, the material roll on it is driven to rotate, thereby achieving downstream unwinding and output of the material strip. When the transfer shaft 311 needs to be docked with the unwinding shaft 11, the drive assembly 33 first drives the transfer assembly 31 to move along the first direction X toward the unwinding mechanism 10 until the transfer shaft 311 of the transfer assembly 31 and the unwinding shaft 11 of the unwinding mechanism 10 are axially opposite to each other. Then, the unwinding shaft 11 is controlled to move along its own axis toward the transfer shaft 311 until the unwinding shaft 11 and the transfer shaft 311 are axially docked.

[0052] It should be noted that the unwinding shaft 11 can be driven to rotate around its own axis by a motor, or the unwinding shaft 11 can be driven to move along its own axis by a linear module. Relatively mature existing technologies can be used to achieve the rotation and axial movement of the unwinding shaft 11, and no limitation is made here.

[0053] Please see Figure 1 and Figure 3 In the embodiments of this application, the storage shaft 21 is a hollow shaft with an internal cavity. The storage shaft 21 also has a clearance groove 212 communicating with the cavity, extending longitudinally along the axial direction of the storage shaft 21. The storage mechanism 20 further includes a transmission unit (not shown) disposed within the cavity of the storage shaft 21. The input end of the transmission unit is connected to the driving end of the second driving member 23, and the output end of the transmission unit passes through the clearance groove 212 and is connected to the second pushing member 22. Thus, the transmission unit transmits the power output by the second driving member 23 to the second pushing member 22, thereby driving the second pushing member 22 to move axially along the storage shaft 21.

[0054] Furthermore, the transmission unit includes a lead screw and a moving component. The lead screw is rotatably connected to the cavity of the storage shaft 21, and the axial direction of the lead screw is aligned with the axial direction of the storage shaft 21. One end of the lead screw extends out of the storage shaft 21 and is coaxially connected to the output shaft of the second drive member 23, enabling the second drive member 23 to drive the lead screw to rotate around its own axis. The moving component is threaded onto the lead screw and passes through the clearance groove 212 to connect with the second pusher member 22, so that when the second drive member 23 drives the lead screw to rotate, it can drive the moving component to move along the axial direction of the lead screw, thereby causing the moving component to drive the second pusher member 22 to move along the axial direction of the storage shaft 21. Optionally, the second drive member 23 can be a motor.

[0055] In a specific embodiment, the storage mechanism 20 further includes a second mounting base 24 and a moving drive component 25. The storage shaft 21 and the second drive component 23 are both mounted on the second mounting base 24. The second mounting base 24 is mounted on the drive end of the moving drive component 25, enabling the moving drive component 25 to drive the second mounting base 24 to move axially along the storage shaft 21. Thus, when the transfer shaft 311 needs to be docked with the storage shaft 21, firstly, the drive component 33 drives the transfer component 31 to move towards the storage shaft 21 along the first direction X until the transfer shaft 311 and the storage shaft 21 are axially opposite each other. Then, the moving drive component 25 drives the second mounting base 24 to move axially along the storage shaft 21, causing the second mounting base 24 to gradually bring the storage shaft 21 closer to the transfer shaft 311 until the storage shaft 21 and the transfer shaft 311 are axially docked. Optionally, the moving drive component 25 can be a linear module.

[0056] Specifically, in this embodiment, the two ends of the storage shaft 21 are a mounting end a1 and an inlet / outlet end a2, respectively. The mounting end a1 of the storage shaft 21 is fixedly mounted on the second mounting base 24. One end of the lead screw passes through the mounting end a1 of the storage shaft 21 and is coaxially connected to the output shaft of the second drive member 23. Under the driving action of the second drive member 23, the second pusher 22 moves along the axial direction of the storage shaft 21 towards the inlet / outlet end a2, thereby pushing the material roll on the storage shaft 21 to detach from the storage shaft 21 from the inlet / outlet end a2.

[0057] Furthermore, a pusher block 221 is provided on the side of the second pusher 22 facing the inlet / outlet end a2, so that when the second pusher 22 pushes the material roll, the pusher block 221 contacts the material roll.

[0058] It should be noted that there can be one, two, or more pusher blocks 221, as long as they can stably push the material roll; no limitation is made here. The shape of the pusher block 221 can be cylindrical, frustum-shaped, or cuboid, etc., as long as it can stably push the material roll; no limitation is made here.

[0059] Please see Figure 1and Figure 4 In the embodiments of this application, the transfer assembly 31 further includes a third mounting base 314, a second guide rod 315, and a second limiting member 316. The third mounting base 314 is connected to the drive end of the drive assembly 33 and has a second guide hole. The second guide rod 315 passes through the second guide hole of the third mounting base 314 and is slidable along the second guide hole. A third pusher 312 is connected to one end of the second guide rod 315, and the second limiting member 316 is connected to the other end of the second guide rod 315. A third drive member 313 is mounted on the third mounting base 314, and the drive end of the third drive member 313 is connected to the third pusher 312. Thus, the second guide rod 315 guides the axial movement of the third pusher 312 along the transfer shaft 311, and the second limiting member 316 limits the maximum stroke of the third pusher 312, preventing the second guide rod 315 from dislodging from the second guide hole. Optionally, the third drive member 313 can be a cylinder.

[0060] Furthermore, the third mounting base 314 has two second guide holes and two second guide rods 315. The two second guide rods 315 pass through the two second guide holes respectively, the third pusher 312 is connected to the same end of the two second guide rods 315, and the second limiting member 316 is connected to the other end of the two second guide rods 315. In this way, the movement of the third pusher 312 is guided simultaneously by the two second guide rods 315, making the pushing action of the third pusher 312 more stable and reliable.

[0061] Please continue reading Figure 1 As shown in the embodiments of this application, there are two unwinding mechanisms 10. The rolls loaded on the two unwinding mechanisms 10 can be alternately used as working rolls A1 and spare rolls A2, respectively. That is, when one unwinding mechanism 10 is loaded with working roll A1, the other unwinding mechanism 10 is loaded with spare roll A2. The unwinding mechanism 10 loaded with working roll A1 drives the working roll A1 downstream to unwind and output the working strip. The drive assembly 33 can drive the transfer assembly 31 to move until the transfer shaft 311 is axially aligned with the unwinding shaft 11 of one of the unwinding mechanisms 10, thereby pushing the drum on the unwinding shaft 11 onto the transfer shaft 311 or pushing the roll on the transfer shaft 311 onto the unwinding shaft 11. The drive assembly 33 can also drive the transfer mechanism 30 to move to the transfer shaft 311 and axially engage with the unwinding shaft 11 of another unwinding mechanism 10, thereby pushing the material cylinder on the unwinding shaft 11 onto the transfer shaft 311 or pushing the material roll on the transfer shaft 311 onto the unwinding shaft 11.

[0062] Optionally, the two unwinding mechanisms 10 are arranged at intervals along the first direction X, such that the unwinding shaft 11, waste shaft 40 and storage shaft 21 of the two unwinding mechanisms 10 are arranged at intervals along the first direction X in sequence. This ensures that during the process of the drive assembly 33 driving the transfer assembly 31 to move along the first direction X, the transfer shaft 311 can pass through the two unwinding shafts 11, waste shaft 40 and storage shaft 21 in sequence, which helps to simplify the transfer path of the material cylinder and the material roll and improve production efficiency.

[0063] In embodiments of this application, the roll-changing device further includes a tape-connecting mechanism 40, a starting mechanism 50, and a glue-supplying mechanism 60. The tape-connecting mechanism 40 is arranged downstream of the two unwinding mechanisms 10, such that the unwinding shaft 11 of one of the unwinding mechanisms 10 drives the working material roll A1 on it to unwind and output the working material tape to the tape-connecting mechanism 40. The tape-connecting mechanism 40 can cut the passing working material tape and adsorb and fix the downstream cut end of the working material tape. The starting mechanism 50 can move to the glue-supplying mechanism 60 and clamp the tape provided by the glue-supplying mechanism 60. The starting mechanism 50 can also move to the spare material roll A2 on the unwinding shaft 11 and use the tape to adhere the starting end A21 of the material roll A2. The starting mechanism 50 is also used to move to the tape-connecting mechanism 40 and adhere the downstream cut end of the working material tape, thereby adhering the starting end A21 of the spare material tape and the downstream cut end of the working material tape to the same tape, thus realizing the connection between the working material tape and the spare material tape.

[0064] During use, one of the unwinding mechanisms 10 loads a working material roll A1 onto its unwinding shaft 11, and drives the working material roll A1 to rotate and unwind downstream to output the working material strip; the other unwinding mechanism 10 loads a spare material roll A2 onto its unwinding shaft 11. The starting mechanism 50 moves to the spare material roll A2 and uses adhesive tape to pick up the starting end A21 of the strip on the spare material roll A2.

[0065] When the strip on the working material roll A1 is about to be unwound and a changeover is needed, firstly, the tape receiving mechanism 40 cuts the passing working material roll and holds the downstream cut end formed after the working material roll is cut. Then, the starting mechanism 50 moves from the spare material roll A2 to the tape receiving mechanism 40 (the starting end A21 of the strip on the spare material roll A2 moves with the starting mechanism 50 and pulls out the spare material roll), so that the starting mechanism 50 uses the tape to hold the downstream cut end of the working material roll. Then, the starting mechanism 50 releases the tape, the spare material roll A2 is switched to the working material roll A1, and the working material roll continues to be unwound downstream. At this time, the transfer shaft 311 can be used to unload the material from the unwinding shaft 11, and the material roll on the storage shaft 21 can be transferred to the unwinding shaft 11 (this material roll serves as the spare material roll A2), preparing for the next changeover.

[0066] Please see Figure 1 , Figure 4and Figure 5 Specifically, in this embodiment, the starting mechanism 50 is installed at the driving end of the driving assembly 33, thereby driving the starting mechanism 50 to move between the glue supply mechanism 60, the unwinding mechanism 10, and the tape receiving mechanism 40. That is, the driving assembly 33 can drive the starting mechanism 50 to the glue supply mechanism 60, so that the starting mechanism 50 can grip the tape provided by the glue supply mechanism 60; the driving assembly 33 can also drive the starting mechanism 50 to the unwinding mechanism 10, so that the starting mechanism 50 can use the tape to adhere to the starting end A21 of the spare roll A2 on the unwinding mechanism 10; the driving assembly 33 can also drive the starting mechanism 50 to the tape receiving mechanism 40, so that the starting mechanism 50 can use the tape to adhere to the downstream cut end of the working tape that is adsorbed and fixed by the tape receiving mechanism 40.

[0067] It should be noted that the drive assembly 33 can drive the transfer mechanism 30 to move and complete the transfer of the material cylinder and the material roll. It can also drive the starting mechanism 50 to move and complete the clamping of the tape, the adhesion of the starting end A21 of the spare material roll A2 and the downstream cutting end of the working material roll. This avoids the need to configure two drive assemblies 33 to drive the transfer mechanism 30 and the starting mechanism 50 to move respectively, which greatly simplifies the equipment structure and reduces the size and cost of the equipment.

[0068] Specifically, in this embodiment, the drive assembly 33 includes a fourth drive member 331, a first transfer seat 332, a fifth drive member 333, a second transfer seat 334, a sixth drive member 335, and a third transfer seat 336. The first transfer seat 332 is mounted on the drive end of the fourth drive member 331, enabling the fourth drive member 331 to drive the first transfer seat 332 to move. The third mounting seat 314 of the transfer mechanism 30 is mounted on the first transfer seat 332, enabling the transfer mechanism 30 to move along with the first transfer seat 332. The fifth drive member 333 is mounted on the first transfer seat 332, enabling the fifth drive member 333 to move along with the first transfer seat 332. The second transfer seat 334 is mounted on the drive end of the fifth drive member 333, enabling the fifth drive member 333 to drive the second transfer seat 334 to move relative to the first transfer seat 332. The sixth drive member 335 is mounted on the second transfer seat 334, enabling the sixth drive member 335 to move along with the second transfer seat 334. The third transfer seat 336 is mounted on the drive end of the sixth drive member 335, enabling the sixth drive member 335 to drive the third transfer seat 336 to move relative to the second transfer seat 334. The aforementioned starting mechanism 50 is mounted on the third transfer seat 336, allowing the starting mechanism 50 to move together with the third transfer seat 336. Thus, the fourth drive member 331 drives the transfer assembly 31 to move between the unwinding shaft 11 of the unwinding mechanism 10, the storage shaft 21 of the storage mechanism 20, and the waste shaft 40, thereby realizing the transfer of the material cylinder and the material roll. The fourth drive member 331, the fifth drive member 333, and the sixth drive member 335 drive the starting mechanism 50 to move between the spare material roll A2 and the tape receiving mechanism 40 on the unwinding mechanism 10, thereby realizing the adhesion of the starting end A21 of the tape on the spare material roll A2 and the adhesion of the downstream cut end of the working tape.

[0069] Optionally, the fourth driving member 331 drives the first transfer seat 332 to move along the first direction X, the fifth driving member 333 drives the second transfer seat 334 to move along the second direction Y, and the sixth driving member 335 drives the third transfer seat 336 to move along the third direction Z. Thus, under the driving action of the fourth driving member 331, the fifth driving member 333, and the sixth driving member 335, the third transfer seat 336 can drive the starting mechanism 50 to move along the first direction X, the second direction Y, and the third direction Z. The first direction X, the second direction Y, and the third direction Z intersect each other. Preferably, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0070] Specifically Figure 1 In the embodiment shown, the first direction X is the left-right direction, the second direction Y is the direction perpendicular to the paper, and the third direction Z is the up-down direction.

[0071] It should be noted that the fourth drive component 331 can be a linear module, and the fifth drive component 333 can be a cylinder.

[0072] Optionally, the drive assembly 33 further includes a linear guide 3321 that extends longitudinally along a first direction X. The first transfer seat 332 is slidably connected to the linear guide 3321, thereby guiding the movement of the first transfer seat 332 along the first direction X using the linear guide 3321.

[0073] Optionally, the drive assembly 33 further includes a guide rod 3324 and a limiting plate 3326. A guide hole is provided on the first transfer seat 332, extending through the first transfer seat 332 along the second direction Y. The guide rod 3324 passes through the guide hole and is movable along the axial direction of the guide hole. The limiting plate 3326 is fixedly connected to one end of the guide rod 3324, and the second transfer seat 334 is fixedly connected to the other end of the guide rod 3324, thereby guiding the movement of the second transfer seat 334 relative to the first transfer seat 332 along the second direction Y using the guide rod 3324. The limiting plate 3326 limits the movement of the guide rod 3324 along the guide hole, preventing the guide rod 3324 from dislodging from the guide hole. It should be noted that the number of guide rods 3324 can be two or more, as long as the guiding function is achieved; this is not limited here.

[0074] Optionally, the second transfer seat 334 is provided with a first slide rail 3344 extending longitudinally in the third direction Z, and the third transfer seat 336 is provided with a first slider 3361. The first slider 3361 is slidably connected to the first slide rail 3344, thereby using the first slide rail 3344 to guide the movement of the third transfer seat 336 relative to the second transfer seat 334 in the third direction Z.

[0075] Optionally, the drive assembly 33 further includes a transmission unit connected between the sixth drive member 335 and the third transfer seat 336, for converting the rotational motion output by the sixth drive member 335 into linear motion of the third transfer seat 336 along the third direction Z. Optionally, the sixth drive member 335 may be a motor.

[0076] Optionally, the transmission unit includes a driving wheel 3341, a driven wheel 3342, and a transmission belt 3343. The driving wheel 3341 is mounted on the output shaft of the sixth drive member 335, thereby enabling the sixth drive member 335 to drive the driving wheel 3341 to rotate. The driven wheel 3342 is rotatably connected to the second transfer seat 334 and is spaced apart from the driving wheel 3341 along the third direction Z. The transmission belt 3343 is sleeved between the driving wheel 3341 and the driven wheel 3342, so that when the driving wheel 3341 rotates, it can drive the transmission belt 3343 to move sequentially forward between the driving wheel 3341 and the driven wheel 3342. The third transfer seat 336 is connected to the transmission belt 3343, so that the transmission belt 3343 can drive the third transfer seat 336 to move relative to the second transfer seat 334 along the third direction Z. Thus, in actual use, the sixth driving component 335 drives the drive wheel 3341 to rotate, thereby driving the transmission belt 3343 to move, so that the transmission belt 3343 drives the third transfer seat 336 to move relative to the second transfer seat 334 along the third direction Z.

[0077] It should be noted that the transmission unit is not limited to a belt drive structure. In other embodiments, a chain drive structure or a gear and rack drive structure can also be used, as long as it can drive the third transfer seat 336 to move relative to the second transfer seat 334 in the third direction Z. This is not limited here.

[0078] Please see Figure 4 and Figure 5 In an embodiment of this application, the starting mechanism 50 includes a clamping drive member 51, a first clamping member 52, and a second clamping member 53. The first clamping member 52 and the second clamping member 53 are arranged opposite to each other, forming a clamping space between them for clamping the tape. At least one of the first clamping member 52 and the second clamping member 53 is connected to the driving end of the clamping drive member 51, so that the clamping drive member 51 can drive the first clamping member 52 and the second clamping member 53 to clamp or release the tape between them. The second clamping member 53 has adsorption surfaces 531 on both opposite sides. When the tape is clamped between the first clamping member 52 and the second clamping member 53, the two ends of the tape hang down onto the two adsorption surfaces 531 of the second clamping member 53, so that the two adsorption surfaces 531 of the second clamping member 53 respectively adsorb and fix the two ends of the tape.

[0079] In actual use, the drive assembly 33 drives the starting mechanism 50 to move to the glue supply mechanism 60, so that the tape provided by the glue supply mechanism 60 enters between the first clamping member 52 and the second clamping member 53. Under the driving action of the clamping drive 51, the first clamping member 52 and the second clamping member 53 clamp the tape, and the two ends of the tape hang down onto the two adsorption surfaces 531 respectively, and are then adsorbed and fixed by the two adsorption surfaces 531.

[0080] When the strip on the working material roll A1 is almost unwound, the unwinding mechanism 10 containing the working material roll A1 stops unwinding, and the tape-joining mechanism 40 cuts the passing working material strip and holds the downstream cut end of the working material strip in place. Then, the drive assembly 33 drives the starting mechanism 50 to move to the unwinding mechanism 10 containing the spare material roll A2, so that one adsorption surface 531 of the second clamping member 53 abuts against the starting end A21 of the strip on the spare material roll A2, thereby causing the tape on the adsorption surface 531 to adhere to the starting end A21 of the strip on the spare material roll. Then, the drive assembly 33 drives the starting mechanism 50 to move to the tape-joining mechanism 40, so that the other adsorption surface 531 of the second clamping member 53 abuts against the downstream cut end of the working material strip held in place by the tape-joining mechanism 40, thereby causing the tape on the adsorption surface 531 to adhere to the downstream cut end of the working material strip. At this point, the starting end A21 of the spare material strip is bonded to the downstream cut end of the working material strip via the same adhesive tape, thus achieving the connection between the spare material strip and the working material strip. Under the driving action of the clamping drive 51, the first clamping member 52 and the second clamping member 53 release the adhesive tape and, under the driving action of the drive assembly 33, move away from the connecting mechanism 40. At this time, the spare material roll A2 switches to the working material roll A1, and continues to unwind and output the working material strip downstream, thus achieving automatic roll changing.

[0081] Thus, the aforementioned roll changing device automatically picks up and lifts the starting end A21 of the material strip on the spare roll A2 through the starting mechanism 50, and then the auxiliary tape connecting mechanism 40 completes the tape connecting action between the working material strip and the spare material strip. This helps to simplify the equipment structure, improve the automation level of the equipment, reduce labor costs, and improve production efficiency.

[0082] It should be noted that the two adsorption surfaces 531 of the second clamping member 53 can adsorb and fix the tape using negative pressure adsorption. Specifically, the adsorption surface 531 has multiple holes, each of which is connected to an external negative pressure source through a pipe. When the tape needs to be adsorbed, the external negative pressure source evacuates air, thereby creating negative pressure in each hole, which in turn adsorbs the tape onto the adsorption surface 531. When the tape is no longer needed, the external negative pressure source stops evacuating the vacuum, breaking the vacuum in each hole and releasing the tape from adsorption. The number and arrangement of the holes on the adsorption surface 531 are not limited here, as long as they can achieve the adsorption and fixation of the tape.

[0083] It should be noted that the adhesive tape provided by the adhesive supply mechanism 60 can be divided into a first segment and two second segments, which are respectively connected to the two ends of the first segment. When the starting mechanism 50 picks up the adhesive, the first segment of the tape is clamped and fixed by the first clamping member 52 and the second clamping member 53, and the two adsorption surfaces 531 on the second clamping member 53 respectively adsorb and fix the two second segments of the tape.

[0084] Please see Figure 7 and Figure 8In embodiments of this application, the adhesive supply mechanism 60 includes an adhesive tape unwinding assembly 61 (see...). Figure 1 The tape assembly includes a clamping component 62, a cutting component 63, and a pulling component 64. The tape unwinding component 61 unwinds the tape material into the clamping component 62, which clamps or releases the passing tape material. The pulling component 64 is spaced apart from the clamping component 62 along a first direction X. The pulling component 64 clamps the tape material at the clamping component 62 and pulls out a certain length of tape material along the first direction X. The cutting component 63 is arranged on the side of the clamping component 62 facing it and cuts the passing tape material. The portion of the tape material that is cut and located between the pulling component 64 and the cutting component 63 constitutes the aforementioned tape.

[0085] Thus, when adhesive needs to be removed, the adhesive pulling component 64 moves closer to the adhesive clamping component 62 until it clamps the starting end of the adhesive tape. Then, the adhesive clamping component 62 releases the passing adhesive tape, and the adhesive pulling component 64 moves away from the clamping component 62 until a certain length of adhesive tape is pulled out. At this point, the adhesive clamping component 62 clamps the passing adhesive tape again. The drive component 33 drives the starting component 50 to move to a position between the cutting component 63 and the pulling component 64, so that the adhesive tape between the cutting component 63 and the pulling component 64 enters between the first clamping member 52 and the second clamping member 53. Then, the clamping drive component 51 drives the first clamping member 52 and the second clamping member 53 to clamp the adhesive tape between them. Then, the tape cutting component 63 cuts the tape material, and the tape pulling component 64 releases the tape material. At this time, the tape formed by cutting the tape material is clamped and fixed between the first clamping member 52 and the second clamping member 53, thus realizing the removal of the tape.

[0086] In a specific embodiment, the roll-changing device further includes a smoothing mechanism 70, which includes a mounting base 71 and a first smoothing member 72 and a second smoothing member 73, both mounted on the mounting base 71. A smoothing channel is formed between the first smoothing member 72 and the second smoothing member 73. Under the driving action of the driving assembly 33, the first clamping member 52 and the second clamping member 53 of the starting mechanism 50 pass sequentially through the smoothing channel between the first smoothing member 72 and the second smoothing member 73. During the process of the second clamping member 53 passing through the smoothing channel, the first smoothing member 72 and the second smoothing member 73 respectively abut against the two adsorption surfaces 531 on the second clamping member 53, thereby pressing the two second segments of the tape flat onto the two adsorption surfaces 531, ensuring that the two adsorption surfaces 531 respectively adsorb and fix the two second segments of the tape.

[0087] Specifically, in this embodiment, the smoothing mechanism 70 is arranged above the space between the tape cutting assembly 63 and the tape pulling assembly 64. This allows the starting mechanism 50 to grip the tape using the first clamping member 52 and the second clamping member 53. As the driving assembly 33 drives the starting mechanism 50 to move upward, the first clamping member 52 and the second clamping member 53 can pass through the smoothing channel between the first smoothing member 72 and the second smoothing member 73 in sequence. This ensures that the two second segments of the tape are flattened onto the two adsorption surfaces 531 under the action of the first smoothing member 72 and the second smoothing member 73, respectively. This, in turn, ensures that the two adsorption surfaces 531 of the second clamping member 53 adsorb and fix the two second segments of the tape.

[0088] In some embodiments, the first smoothing member 72 and the second smoothing member 73 can be flattening plates. When the second clamping member 53 passes through the smoothing channel, the flattening plate is used to flatten the second section of the tape onto the adsorption surface 531. In this way, the second section of the tape is smoothed using a flattening plate, which has a simple structure and low cost.

[0089] Of course, in other embodiments, the first smoothing member 72 and the second smoothing member 73 may also be smoothing rollers. When the second clamping member 53 passes through the smoothing channel, the smoothing rollers are used to roll the second section of the tape onto the adsorption surface 531. As long as the second section of the tape can be smoothed onto the adsorption surface 531, it is not limited here. In some other embodiments, one of the first smoothing member 72 and the second smoothing member 73 may be a smoothing plate and the other may be a smoothing roller. As long as the two second sections of the tape can be smoothed onto the two adsorption surfaces 531 respectively, it is not limited here.

[0090] In a specific embodiment, the smoothing mechanism 70 further includes a first moving seat 74, a second moving seat 75, and a first elastic member 76. Both the first moving seat 74 and the second moving seat 75 are mounted on the mounting base 71. The first smoothing member 72 is mounted on the first moving seat 74, and the second smoothing member 73 is mounted on the second moving seat 75. The first moving seat 74 and the second moving seat 75 can move closer to or further away from each other, thereby causing the first smoothing member 72 and the second smoothing member 73 to move closer to or further away from each other. The two ends of the first elastic member 76 are respectively connected to the first moving seat 74 and the second moving seat 75, giving the first moving seat 74 and the second moving seat 75 an elastic force that tends to move closer to each other. Thus, when the first clamping member 52 and the second clamping member 53 pass through the smoothing channel, the first clamping member 52 and the second clamping member 53 are used to separate the first smoothing member 72 and the second smoothing member 73, that is, the first moving seat 74 and the second moving seat 75 overcome the elastic force provided by the first elastic member 76 and move away from each other (at this time, the stretching amount of the first elastic member 76 increases). When the first clamping member 52 and the second clamping member 53 leave the smoothing channel, the first moving seat 74 and the second moving seat 75, under the elastic force provided by the first elastic member 76, drive the first smoothing member 72 and the second smoothing member 73 to move closer to each other and reset. That is, when the first clamping member 52 or the second clamping member 53 has not entered the smoothing channel, the distance between the first smoothing member 72 and the second smoothing member 73 is less than the width of the first clamping member 52 and the second clamping member 53, thereby ensuring that the first smoothing member 72 and the second smoothing member 73 respectively press against the two adsorption surfaces 531 of the second clamping member 53 during the passage of the second clamping member 53 through the smoothing channel. Optionally, the first elastic member 76 can be a spring.

[0091] Furthermore, the smoothing mechanism 70 also includes a limiting block 77 mounted on the mounting base 71. The limiting block 77 is located between the first moving base 74 and the second moving base 75, thereby limiting the minimum distance between the first moving base 74 and the second moving base 75, that is, limiting the minimum distance between the first smoothing member 72 and the second smoothing member 73, thereby preventing the first clamping member 52 from being unable to enter between the first smoothing member 72 and the second smoothing member 73 due to the distance between the first smoothing member 72 and the second smoothing member 73 being too small.

[0092] It should be noted that it is not limited to both the first moving seat 74 and the second moving seat 75 being able to move relative to the mounting seat 71. In other embodiments, one of the first moving seat 74 and the second moving seat 75 may be able to move relative to the mounting seat 71, while the other is fixed relative to the mounting seat 71. As long as it is possible to achieve the goal of the first smoothing member 72 and the second smoothing member 73 pressing against the two adsorption surfaces 531 respectively when the second clamping member 53 passes through the smoothing channel, it is not limited here.

[0093] It should also be noted that the two ends of the first elastic member 76 are not limited to being connected to the first moving seat 74 and the second moving seat 75 respectively. In some other embodiments, the two ends of the first elastic member 76 may also be connected to the first smoothing member 72 and the second smoothing member 73 respectively, which is not limited here.

[0094] Please see Figure 6 Specifically, in this embodiment, the first clamping member 52 has a first guide surface a1 and a second guide surface a2 on the side opposite to the second clamping member 53, and the arrangement direction of the first guide surface a1 and the second guide surface a2 is consistent with the arrangement direction of the two adsorption surfaces 531. Figure 6 In the embodiment shown, the first clamping member 52 and the second clamping member 53 are arranged at intervals along the third direction Z. The two adsorption surfaces 531 are located on both sides of the second clamping member 53 in the first direction X. The length direction of the first clamping member 52 and the second clamping member 53 is the second direction Y. The first guide surface a1 and the second guide surface a2 are arranged along the first direction X. The two adsorption surfaces 531 are also arranged along the first direction X. The first smoothing member 72 and the second smoothing member 73 are also arranged along the first direction X. That is to say, the arrangement directions of the first guide surface a1 and the second guide surface a2, the arrangement direction of the two adsorption surfaces 531, and the arrangement directions of the first smoothing member 72 and the second smoothing member 73 are all consistent.

[0095] In the direction from the first clamping member 52 to the second clamping member 53, the distance between the first guide surface a1 and the second guide surface a2 gradually increases. Thus, as the driving assembly 33 drives the starting mechanism 50 into the smoothing channel along the third direction Z, the first smoothing member 72 and the second smoothing member 73 abut against the first guide surface a1 and the second guide surface a2, respectively. As the first clamping member 52 continues to enter the smoothing channel, the first smoothing member 72 and the second smoothing member 73 slide along the first guide surface a1 and the second guide surface a2, respectively. Because the distance between the first guide surface a1 and the second guide surface a2 gradually increases, the first smoothing member 72 and the second smoothing member 73 are gradually spread apart (i.e., the distance between them gradually increases), ensuring that when the second clamping member 53 enters the smoothing channel, the first smoothing member 72 and the second smoothing member 73 remain in contact with the two adsorption surfaces 531, respectively. It should be noted that the first guide surface a1 and the second guide surface a2 can be planar or curved, as long as they can achieve the guiding function; no limitation is made here.

[0096] Please continue reading Figure 7 and Figure 8 In some embodiments, the glue clamping assembly 62, glue pulling assembly 64, and glue cutting assembly 63 of the glue supply mechanism 60 are all mounted on the mounting base 71 of the smoothing mechanism to facilitate the assembly and disassembly of the glue supply mechanism 60 and the smoothing mechanism 70.

[0097] Specifically, the adhesive clamping assembly 62 includes a first adhesive clamping drive and two first adhesive clamping blocks. The first adhesive clamping drive is mounted on the mounting base 71. The two first adhesive clamping blocks are respectively mounted on the two drive ends of the first adhesive clamping drive, which is used to drive the two first adhesive clamping blocks to clamp or release the passing adhesive tape. Optionally, the first adhesive clamping drive can be a gripper cylinder.

[0098] Specifically, the adhesive stretching assembly 64 includes an adhesive stretching drive 641, a movable base 642, a second adhesive clamping drive 643, and two second adhesive clamping blocks 644. The adhesive stretching drive 641 is mounted on a mounting base 71. The movable base 642 is movably connected to the mounting base 71 along a first direction X and is connected to the drive end of the adhesive stretching drive 641. The adhesive stretching drive 641 drives the movable base 642 to move relative to the mounting base 71 along the first direction X, thereby causing the movable base 642 to move closer to or away from the adhesive clamping assembly 62. The second adhesive clamping drive 643 is mounted on the movable base 642, and the two second adhesive clamping blocks 644 are respectively mounted on the two drive ends of the second adhesive clamping drive 643, thereby enabling the second adhesive clamping drive 643 to drive the two second adhesive clamping blocks 644 to clamp or release the starting end of the adhesive tape. It should be noted that in other embodiments, one of the two second clamping blocks 644 may be installed on the driving end of the second clamping drive 643, so that the second clamping drive 643 drives the second clamping block 644 to move closer to or away from the other second clamping block 644, as long as it can clamp or release the passing tape material, and there is no limitation here.

[0099] Optionally, the glue-pulling drive component 641 can be a cylinder, and the second glue-clamping drive component 643 can be a gripper cylinder.

[0100] It should be noted that the movable seat 642 can be mounted on the mounting base 71 by means of guide rods or other guide components, thereby guiding the movement of the movable seat 642 relative to the mounting base 71.

[0101] Specifically, the tape cutting assembly 63 includes a tape cutting drive and a first cutter. The tape cutting drive is mounted on the mounting base 71, and the first cutter is mounted on the drive end of the tape cutting drive, enabling the tape cutting drive to drive the first cutter to move, thereby cutting the tape material in its path. Optionally, the tape cutting drive can be a cylinder.

[0102] Please continue reading Figure 4 and Figure 5In an embodiment of this application, the starting mechanism 50 further includes a rotary drive 54, and a clamping drive 51 is mounted on the drive end of the rotary drive 54. A first clamping member 52 and a second clamping member 53 are respectively mounted on the two drive ends of the clamping drive 51. The rotary drive 54 can drive the clamping drive 51 to rotate, thereby causing the first clamping member 52 and the second clamping member 53 to rotate as a whole. The clamping drive 51 can drive the first clamping member 52 and the second clamping member 53 to clamp or release the tape. Optionally, the rotary drive 54 can be a rotary cylinder, and the clamping drive 51 can be a gripper cylinder.

[0103] Thus, before adhering to the starting end A21 of the strip on the spare roll, the first clamping member 52 and the second clamping member 53 can be rotated as a whole by the rotary drive 54, so that when the starting mechanism 50 moves to the spare roll A2, a certain adsorption surface 531 on the second clamping member 53 faces the starting end A21 of the strip on the spare roll A2, and then the adhesive on the adsorption surface 531 is used to adhere to the starting end A21 of the strip on the spare roll A2. Before adhering to the downstream cut end of the working strip, the first clamping member 52 and the second clamping member 53 can be rotated as a whole by the rotary drive 54, so that when the starting mechanism 50 moves to the tape receiving mechanism 40, another adsorption surface 531 on the second clamping member 53 faces the downstream cut end of the working strip, and then the adhesive on the adsorption surface 531 is used to adhere to the downstream cut end of the working strip.

[0104] It should be noted that the first clamping member 52 and the second clamping member 53 are not limited to being installed on the two driving ends of the same clamping drive member 51. In other embodiments, two clamping drive members 51 may also be provided, both of which are installed on the driving ends of the rotary drive member 54, so that the rotary drive member 54 can drive the two clamping drive members 51 to rotate as a whole. The first clamping member 52 and the second clamping member 53 are respectively installed on the driving ends of the two clamping drive members 51. The two clamping drive members 51 respectively drive the first clamping member 52 and the second clamping member 53 to move closer or further away from each other, so that the first clamping member 52 and the second clamping member 53 together tighten or loosen the tape. Optionally, the two clamping drive members 51 can be cylinders.

[0105] In the embodiments of this application, the starting mechanism 50 is movably connected to the driving end of the driving assembly 33 along the first direction X. The starting mechanism 50 also includes a buffer elastic element 56, which is connected to the third transfer seat 336 and the starting mechanism 50, so that the starting mechanism 50 can float in the first direction X under the action of external force. Thus, when the adsorption surface 531 on the second clamping member 53 of the starting mechanism 50 abuts against the spare material roll A2 under the driving action of the driving assembly 33, the starting mechanism 50 overcomes the elastic force provided by the buffer elastic element 56 under the action of the pressing force provided by the spare material roll A2, and floats along the first direction X, avoiding a hard impact between the second clamping member 53 and the spare material roll A2 that could damage the spare material roll. That is, the buffer elastic element 56 plays a role in buffering the impact between the second clamping member 53 and the spare material roll A2.

[0106] In a specific embodiment, the starting mechanism 50 further includes a sliding seat 55, which is movably connected to the third transfer seat 336 along the first direction X. A rotary drive 54 is mounted on the sliding seat 55, allowing it to move along with the sliding seat 55. The buffer elastic member 56 can be a buffer cylinder, which is mounted on the third transfer seat 336, with its extension / retraction end connected to the sliding seat 55. Thus, in actual use, the extension / retraction end of the buffer cylinder is in the extended state. When the adsorption surface 531 of the second clamping member 53 abuts against the spare material roll A2, the sliding seat 55 floats along the first direction X, and the buffer cylinder provides a buffering effect.

[0107] It should be noted that the buffer elastic element 56 is not limited to a buffer cylinder. In other embodiments, a buffer spring can also be used, as long as it can play a buffering role. No limitation is made here.

[0108] Furthermore, a second slide rail extending longitudinally along the first direction X is installed on the third transfer seat 336, and a second slider is provided on the sliding seat 55. The second slider is slidably connected to the second slide rail, thereby using the second slide rail to guide the movement of the sliding seat 55 relative to the third transfer seat 336 along the first direction X.

[0109] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0110] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
