Description

Technical Field

[0001] This application relates to the technical field of auxiliary processing equipment for paper products, and in particular to a paper waste collection device. Background Technology

[0002] Currently, the production steps for paper bags and other paper products are roughly as follows: preparing raw materials; printing, printing patterns and text onto paper; die-cutting, using a die-cutting machine to cut the paper into the corresponding shapes according to the size and shape requirements of the paper bags; laminating, bonding two or more layers of raw materials together with adhesive to achieve better performance of the packaging film and bag; curing, accelerating the curing speed of the adhesive between the raw materials; slitting, slitting the printed and laminated raw materials into the specifications and models required by the customer; and bag making, making the printed, laminated, and slitting raw materials into various types of bags required by the customer, which can be made into a variety of bag types.

[0003] In the process of paper product processing, in order to ensure the continuity of production, long strips of paper in rolls are usually used as raw materials. Rollers are used to transport the paper rolls, and processing steps such as cutting the raw materials are completed during the transport process.

[0004] Since the paper is cut to adjust its width, a certain width of waste paper is cut off from both sides of the paper's width direction during the cutting process. Because the paper is in a long, rolled shape, the resulting waste paper is also long and thin, with a length close to the length of the original paper. To prevent the waste paper from getting stuck in the equipment, a waste paper collection device is installed.

[0005] Currently, waste paper collection is mostly done using collection bins. These bins are placed under the paper cutting equipment so that the cut waste paper automatically falls into them, thus achieving the purpose of waste paper collection.

[0006] However, because waste paper is lightweight and not fixed, it is easily disturbed when it is windy or when the airflow speed is high. The waste paper between the cutting equipment and the collection box can be blown into the cutting equipment, which can easily damage the cutting equipment or affect its normal operation. Summary of the Invention

[0007] This application provides a paper waste collection device, the purpose of which is to collect waste paper during the paper cutting process, increase the surface tension of the waste paper, and reduce the possibility of waste paper being blown into the cutting equipment.

[0008] The paper waste collection device provided in this application adopts the following technical solution: A paper waste collection device includes a mounting frame, on which a winding mechanism and a guiding mechanism are provided. The winding mechanism includes a winding roller, and one end of the winding roller is coaxially connected to a winding drive component capable of driving the winding roller to rotate.

[0009] The guiding mechanism includes a traction arm, the length direction of which is parallel to the axial direction of the take-up roller, and the traction arm is connected to a reciprocating drive member capable of driving the traction arm to move along the axial direction of the take-up roller.

[0010] A guide arm is provided on the side wall of the traction arm, and the length direction of the guide arm is perpendicular to the length direction of the traction arm.

[0011] By adopting the above technical solution, firstly, a winding mechanism is set on the mounting frame. Through the cooperation of the winding roller and the winding drive, the waste paper generated during cutting can be collected.

[0012] Secondly, the traction arm in the guiding mechanism allows the waste paper strip to pass through the side of the traction arm with the guide arm, and then be wound by the take-up roller. During this process, the traction arm can change the conveying path of the waste paper strip and support it, increasing the surface tension of the waste paper strip. The guide arm on the traction arm, in conjunction with the reciprocating drive that drives the traction arm to move axially along the take-up shaft, further enhances this effect. On the one hand, the traction arm can also change the conveying path of the waste paper strip and support it, increasing the surface tension. On the other hand, it allows the waste paper strip to spirally wind onto the take-up roller along its axial direction, improving the uniformity of the waste paper strip winding.

[0013] In summary, the winding mechanism can wind up the waste paper tape, while the guiding mechanism can increase the surface tension of the waste paper tape during winding, making the waste paper tape less susceptible to wind disturbance. Therefore, the winding of the waste paper tape is more stable and reduces the possibility of the waste paper tape being blown into the cutting equipment.

[0014] Optionally, the take-up roller includes a roller body, and the two ends of the roller body are respectively connected to a first limiting plate and a second limiting plate, the diameters of the first limiting plate and the second limiting plate are both larger than the diameter of the roller body.

[0015] By adopting the above technical solution, the roller body can realize the winding and collection of waste paper strips. The roller body is provided with a first limiting plate and a second limiting plate at both ends. The diameters of the first limiting plate and the second limiting plate are both larger than the diameter of the roller body, so it can prevent the waste paper strips wrapped on the roller body from falling off from both ends of the roller body.

[0016] Optionally, it also includes a synchronous motion mechanism, which includes a drive motor, and the output shaft of the drive motor is coaxially connected to a first drive sprocket;

[0017] The winding drive includes a winding drive shaft, one end of which is coaxially connected to the winding roller, and a winding sprocket and a second drive sprocket are coaxially connected to the winding drive shaft.

[0018] The reciprocating drive component includes a reciprocating lead screw, the traction arm is connected to the reciprocating lead screw in a transmission connection, and a reciprocating sprocket is coaxially connected to the reciprocating lead screw;

[0019] A winding chain is provided between the first drive sprocket and the winding sprocket. The winding chain is sleeved on the outside of the first drive sprocket and the winding sprocket. Both the first drive sprocket and the winding sprocket mesh with the winding chain.

[0020] A reciprocating chain is provided between the second drive sprocket and the reciprocating sprocket. The reciprocating chain is sleeved on the outside of the second drive sprocket and the reciprocating sprocket, and both the second drive sprocket and the reciprocating sprocket mesh with the reciprocating chain.

[0021] By adopting the above technical solution and setting up a synchronous motion mechanism, firstly, the first drive sprocket and the winding sprocket cooperate with the winding chain so that when the drive motor drives the first drive sprocket to rotate, the first drive sprocket can drive the winding sprocket to rotate synchronously, thereby realizing the winding shaft winding the waste paper strip.

[0022] Secondly, the second drive sprocket and the reciprocating sprocket work together with the reciprocating chain to enable the reciprocating drive component to drive the second drive sprocket to rotate, so that the second drive sprocket and the reciprocating sprocket can rotate synchronously. Thus, through the setting of the reciprocating screw, the traction arm can move back and forth.

[0023] Therefore, by coordinating the first drive sprocket, the winding sprocket, the second drive sprocket, and the reciprocating sprocket with the winding chain and the reciprocating chain, synchronous movement of the winding shaft and the traction arm can be achieved.

[0024] Optionally, a switching mechanism is provided on one side of the mounting bracket. The switching mechanism includes a first rotating disk and a rotating motor mounted on the first rotating disk that can drive the first rotating disk to rotate.

[0025] The winding rollers are provided in a plurality of manner, and one winding roller is coaxially arranged with the winding drive component. The winding roller and the winding drive component are detachably connected.

[0026] The axial direction of the take-up roller is parallel to the axial direction of the first rotating disk. One end of the take-up roller is rotatably connected to the first rotating disk. Several take-up rollers are arranged at intervals along the circumference of the first rotating disk.

[0027] By adopting the above technical solution, a switching mechanism is set on one side of the mounting frame. The switching mechanism includes a first rotating disk and a rotating motor, and the rotating motor can drive the first rotating disk to rotate.

[0028] The first rotating disk is equipped with several winding rollers, one of which is coaxially arranged with the winding drive, so that one winding roller can realize the winding of waste paper tape.

[0029] The winding roller and the winding drive are detachably connected. Therefore, after a single winding roller finishes winding the waste paper strip, the winding roller and the winding drive can be separated. At this time, rotating the first rotating disk can switch to a new winding roller and the winding drive being coaxially set. Then, the new winding roller and the winding drive are connected to each other. Since the winding roller is rotatably connected to the first rotating disk, the winding drive can drive the new winding roller to rotate, thus restoring the function of winding the waste paper strip.

[0030] Therefore, by setting up a switching mechanism, new take-up rolls can be switched quickly, reducing the time required to change take-up rolls.

[0031] Optionally, a magnetic coupling is provided between the take-up roller and the take-up drive; the magnetic coupling includes a first half coupling and a plurality of second half couplings, the first half coupling is interconnected with the take-up drive, and the first half coupling is located at the end of the take-up drive facing the take-up roller.

[0032] The second half coupling is provided in a one-to-one correspondence with the take-up roller, and the second half coupling is coaxially connected to the corresponding take-up roller. The second half coupling is located at the end of the corresponding take-up roller facing the take-up drive component.

[0033] By adopting the above technical solution, the setting of the magnetic connector between the winding roller and the winding drive allows the first half coupling and the corresponding second half coupling to be magnetically attracted when the winding roller and the winding drive are coaxial, thus connecting the winding roller and the winding drive. At this time, the winding drive can drive the winding roller to rotate to achieve the winding of the waste paper strip.

[0034] Therefore, a detachable connection between the take-up roller and the take-up drive can be achieved by using a magnetic coupling.

[0035] Optionally, a connecting shaft is provided between the take-up roller and the first rotating disk, one end of the connecting shaft is rotatably connected to the first rotating disk, and the other end of the connecting shaft is coaxially connected to the corresponding second half coupling.

[0036] The winding roller has an insertion hole at one axial end, and the insertion hole is inserted into the corresponding connecting shaft along the axial direction of the winding roller.

[0037] By adopting the above technical solution, a connecting shaft is provided on the first rotating disk, and the connecting shaft is rotatably connected to the first rotating disk. The second half coupling is provided at one end of the corresponding connecting shaft, so the winding drive can drive the corresponding connecting shaft to rotate.

[0038] The winding roller has an insertion hole at one end of its axial direction. The connecting shaft and the corresponding winding roller are connected through the insertion hole. Therefore, the winding roller can be driven by the connecting shaft to realize the winding of the waste paper strip. At the same time, it is also convenient to remove the winding roller from the first rotating disk, so as to facilitate the replacement of the waste paper strip and the replacement of the new winding roller.

[0039] Optionally, the connecting shaft is slidably connected to the inner wall of the corresponding insertion hole along its own axial direction;

[0040] The outer wall of the connecting shaft is provided with a plurality of locking grooves, the locking grooves are opened along the axial direction of the connecting shaft, and the locking grooves pass through the end of the connecting shaft away from the corresponding second half coupling;

[0041] The inner wall of the locking groove is provided with a plurality of locking rods, and the length direction of the locking rods is arranged along the axial direction of the take-up roller;

[0042] The locking rods are configured to correspond one-to-one with the locking slots;

[0043] When the connecting shaft is inserted into the insertion hole, the locking rod is inserted into the corresponding locking groove along its own length direction.

[0044] By adopting the above technical solution, since the connecting shaft is slidably connected to the inner wall of the insertion hole, the take-up roller can be removed from the corresponding connecting shaft by sliding, thus improving the replacement speed of the connecting shaft.

[0045] However, this makes it difficult for the connecting shaft to drive the take-up roller to rotate. Therefore, a locking groove is opened on the connecting shaft, and a locking rod is set in the insertion hole. When the connecting shaft is inserted into the corresponding insertion hole, the locking rod in the insertion hole will be inserted into the corresponding locking groove. At this time, when the connecting shaft is rotated, the connecting shaft can drive the take-up roller to rotate, so that the take-up roller can take up the waste paper strip.

[0046] Optionally, a fixing rod is coaxially connected to the end of the connecting shaft away from the corresponding second half coupling;

[0047] A support base is provided at one axial end of the take-up roller, and a threaded hole is provided on one side of the support base along the axial direction of the take-up roller.

[0048] The fixing rod is inserted into the threaded hole along its own axial direction, and the fixing rod is connected to the inner wall of the threaded hole by threads; the support base abuts against the winding roller along the axial direction of the fixing rod.

[0049] By adopting the above technical solution, since the take-up roller can be detached from the corresponding connecting shaft by sliding, it is easy for the take-up roller to slide along its own axial direction on the connecting shaft. Therefore, a fixing rod is provided at the end of the connecting shaft away from the second half coupling. A support seat is sleeved on the outside of the fixing rod. The support seat has a threaded hole, which is inserted into the fixing rod. The inner wall of the threaded hole is connected to the fixing rod by threads, so the support seat can be fixed to the end of the take-up roller. Thus, the support seat limits the take-up roller along its axial direction, preventing the take-up roller from sliding along its own axial direction on the connecting shaft.

[0050] Optionally, the take-up roller includes a roller body, and the two ends of the roller body are respectively connected to a first limiting disk and a second limiting disk, wherein the diameters of the first limiting disk and the second limiting disk are both larger than the diameter of the roller body;

[0051] The first limiting plate is provided with a cutting mechanism, the cutting mechanism includes a cutting groove, the cutting groove is opened on the side of the first limiting plate facing the second limiting plate, and the length direction of the cutting groove is arranged along the radial direction of the roller body;

[0052] A cutting plate is inserted into the cutting groove. The cutting plate is slidably connected to the inner wall of the cutting groove along the length direction of the cutting groove. A cutting drive component is provided on the side of the cutting plate away from the roller body, which can drive the cutting plate to move along the length direction of the cutting groove.

[0053] By adopting the above technical solution, the cutting mechanism is set on the first limiting plate, and the cutting plate in the cutting mechanism can move towards the roller body under the drive of the cutting drive component.

[0054] Therefore, driven by the traction arm and guide arm, the waste paper strip enters between the cutting plate and the outside of the roller. At this time, the cutting plate moves towards the roller, so that the cutting plate can press the waste paper strip onto the surface of the roller.

[0055] Based on the above principle, the new take-up roll is moved between the currently winding take-up roll and the traction arm. At this time, the waste paper strip passes over the surface of the new take-up roll and is wound up by the current take-up roll. When a new take-up roll needs to be replaced, the guide arm moves the waste paper strip between the cutter plate and the outside of the roll body. The cutter plate then presses the waste paper strip firmly. The rotation of the current take-up roll breaks the waste paper strip, and one end of the waste paper strip is pressed onto the new take-up roll. At this point, the old take-up roll can be switched by the first rotating disc, and the new take-up roll connects to the take-up drive, allowing the new take-up drive roll to directly perform the winding operation.

[0056] Therefore, by setting up a cutting mechanism, the waste paper strip can be cut when the old winding roll finishes winding and fixed to the new winding roll. This facilitates the switching between the old and new winding rolls and allows the machine to start working immediately after the switching is completed, reducing the time required to switch winding rolls.

[0057] Optionally, the second limiting disc has a mounting groove on the side facing the roller body, and the roller body is inserted into the mounting groove along its own axial direction.

[0058] By adopting the above technical solution, the installation groove on the second limiting plate can, on the one hand, realize the installation between the second limiting plate and the roller body; on the other hand, it facilitates the disassembly of the second limiting plate, which also facilitates the peeling of the waste paper strip from the roller body.

[0059] In summary, this application includes at least one of the following beneficial technical effects:

[0060] 1. The winding mechanism can wind up the waste paper tape, while the guiding mechanism can increase the surface tension of the waste paper tape during winding, making the waste paper tape less susceptible to wind disturbance. Therefore, the winding of the waste paper tape is more stable, reducing the possibility of waste paper being blown into the cutting equipment.

[0061] 2. By setting the switching mechanism, new take-up rolls can be switched quickly, reducing the time required to change take-up rolls.

[0062] 3. The magnetic coupling enables a detachable connection between the take-up roller and the take-up drive, reducing manual intervention during the take-up roller switching process.

[0063] 4. By setting up a cutting mechanism, the waste paper strip can be cut when the old winding roll finishes winding and fixed to the new winding roll, reducing manual intervention during the winding roll switching process. Attached Figure Description

[0081] The following is in conjunction with the appendix Figure 1 -Appendix Figure 11 This application will be described in further detail below.

[0082] Example 1:

[0083] A paper waste collection device, as described above Figure 1 and Figure 2 It includes a mounting frame 1, a winding mechanism 2, and a guiding mechanism 3, with the winding mechanism 2 and the guiding mechanism 3 both mounted on the mounting frame 1.

[0084] Reference Figure 1 and Figure 2 The winding mechanism 2 includes a winding roller 21 and a winding drive component 22. The winding drive component 22 includes a winding drive shaft 221, which is mounted on the mounting frame 1 via a bearing seat. The axial direction of the winding drive shaft 221 is horizontal, and one end of the winding drive shaft 221 is coaxially connected to the winding roller 21, which is located outside the mounting frame 1. Therefore, the winding drive shaft 221 can drive the winding roller 21 to move synchronously, so that after the waste paper is wrapped around the outside of the winding roller 21, the winding roller 21 can wind up the waste paper. Thus, the winding roller 21 can tighten the waste paper, increase the surface tension of the waste paper, and reduce the disturbance of the waste paper by airflow.

[0085] Reference Figure 1 and Figure 2 The take-up roller 21 includes a roller body 211, a first limiting disk 212, and a second limiting disk 213. The roller body 211 is coaxially connected to the take-up drive shaft 221. Both axial ends of the roller body 211 are coaxially connected to the first limiting disk 212 and the second limiting disk 213, respectively. The diameters of the first limiting disk 212 and the second limiting disk 213 are both larger than the diameter of the roller body 211. Therefore, when the roller body 211 takes up waste paper, the first limiting disk 212 and the second limiting disk 213 can prevent the waste paper from slipping off from both ends of the roller body 211.

[0086] Reference Figure 1 and Figure 2The guiding mechanism 3 includes a reciprocating drive component 31 and a traction arm 32. The reciprocating drive component 31 includes a reciprocating screw 311, the axial direction of which is parallel to the axial direction of the take-up drive shaft 221. The reciprocating screw 311 is mounted on the outer wall of the mounting frame 1 via a bearing seat. A sliding seat 312 is provided on the reciprocating screw 311, and the reciprocating screw 311 and the sliding seat 312 are connected in a transmission manner. Therefore, when the reciprocating screw 311 rotates, it can drive the sliding seat 312 to reciprocate along the axial direction of the reciprocating screw 311. The traction arm 32 is arranged along the axial direction of the reciprocating screw 311 in the length direction. One end of the traction arm 32 away from the take-up roller 21 in the length direction is connected to the sliding seat 312, and the other end of the traction arm 32 is provided with a guide arm 33. The guide arm 33 is arranged in the vertical direction in the length direction, and the lower end of the guide arm 33 is connected to the traction arm 32.

[0087] Therefore, during the process of the reciprocating screw 311 driving the sliding seat 312 to reciprocate along its own axial direction, the traction arm 32 drives the guide arm 33 to reciprocate along the axial direction of the reciprocating screw 311. Thus, during the winding process of the take-up roller 21, the waste paper strip will first pass through the guide arm 33, so the guide arm 33 drives the waste paper strip to reciprocate along the axial direction of the take-up roller 21, so that the waste paper can be evenly wound onto the take-up roller 21.

[0088] Reference Figure 1 and Figure 2 The mounting frame 1 is also equipped with a synchronous motion mechanism 4, which includes a drive motor 41. The drive motor 41 is mounted on the mounting frame 1. The axial direction of the output shaft of the drive motor 41 is parallel to the axial direction of the winding drive shaft 221. The output shaft of the drive motor 41 is coaxially connected to a first drive sprocket 42. The winding drive shaft 221 is coaxially connected to a winding sprocket 43 and a second drive sprocket 44. The reciprocating screw 311 is coaxially connected to a reciprocating sprocket 45. The winding sprocket 43 and the first drive sprocket 42 are aligned with each other along the axial direction of the winding drive shaft 221. The second drive sprocket 44 and the reciprocating sprocket 45 are also aligned with each other along the axial direction of the winding drive shaft 221.

[0089] A winding chain 46 is provided between the winding sprocket 43 and the first drive sprocket 42. The winding chain 46 is sleeved on the outside of the winding sprocket 43 and the first drive sprocket 42, and the winding chain 46, the winding sprocket 43, and the first drive sprocket 42 are all meshed. A reciprocating chain 47 is provided between the second drive sprocket 44 and the reciprocating sprocket 45. The reciprocating chain 47 is sleeved on the outside of the second drive sprocket 44 and the reciprocating sprocket 45, and the reciprocating chain 47, the second drive sprocket 44, and the reciprocating sprocket 45 are all meshed.

[0090] Therefore, the drive motor 41 within the synchronous motion mechanism 4 drives the first drive sprocket 42 to rotate. The first drive sprocket 42, through the winding sprocket 43, drives the winding sprocket 43 to rotate, thereby driving the winding roller 21 to wind up the paper. Simultaneously, the winding roller 21 drives the second drive sprocket 44 to rotate. The second drive sprocket 44, through the reciprocating chain 47, drives the reciprocating sprocket 45 to rotate, which in turn drives the reciprocating screw 311 to rotate, realizing the reciprocating motion of the traction arm 32 and the guide arm 33. Thus, the winding of the waste paper strip by the winding roller 21 and the guiding of the waste paper strip by the guide arm 33 can be performed synchronously.

[0091] The transmission ratio between the first drive sprocket 42, the winding sprocket 43, the second drive sprocket 44, and the reciprocating sprocket 45 is obtained based on actual debugging.

[0092] The implementation principle of this application embodiment is as follows: the waste paper is wound up by the winding mechanism 2, and the guide mechanism 3 enables the waste paper to move along the axial direction of the winding roller 21 during the winding process, so that the waste paper can be evenly wound onto the winding roller 21. Therefore, the waste paper can be collected through the cooperation of the winding mechanism 2 and the guide mechanism 3.

[0093] Example 2:

[0094] A paper waste collection device, as described above Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the synchronous motion mechanism 4 further includes a first intermediate sprocket 400 and a second intermediate sprocket 401. The first intermediate sprocket 400 and the second intermediate sprocket 401 are coaxially connected and mounted on the side wall of the mounting frame 1. Both the first intermediate sprocket 400 and the second intermediate sprocket 401 are rotatably connected to the side wall of the mounting frame 1. The first intermediate sprocket 400 and the second intermediate sprocket 401 are located vertically between the winding drive shaft 221 and the drive motor 41. The first intermediate sprocket 400 and the first drive sprocket 42 are flush with each other along the axial direction of the winding drive shaft 221, and the second intermediate sprocket 401 and the winding sprocket 43 are flush with each other along the axial direction of the winding drive shaft 221.

[0095] Reference Figure 3 and Figure 4A first intermediate chain 402 is provided between the first intermediate sprocket 400 and the first drive sprocket 42. The first intermediate chain 402 is sleeved on the outside of the first intermediate sprocket 400 and the first drive sprocket 42, and the first intermediate chain 402 meshes with both the first intermediate sprocket 400 and the first drive sprocket 42. A second intermediate chain 403 is provided between the second intermediate sprocket 401 and the take-up sprocket 43. The second intermediate chain 403 is sleeved on the outside of the second intermediate sprocket 401 and the take-up sprocket 43, and the second intermediate chain 403 meshes with both the second intermediate sprocket 401 and the take-up sprocket 43.

[0096] The transmission ratio between the first intermediate sprocket 400 and the second intermediate sprocket 401 is obtained through actual debugging.

[0097] The implementation principle of this application embodiment is as follows: through the cooperative arrangement of the first intermediate sprocket 400, the second intermediate sprocket 401, the first intermediate chain 402, and the second intermediate chain 403, the driving action of the first drive sprocket 42 on the take-up sprocket 43 is realized. Furthermore, the cooperation of the first intermediate sprocket 400 and the second intermediate sprocket 401 can reduce the rotational speed of the drive motor 41 transmitted to the take-up drive shaft 221, ensuring that the rotational speed of the take-up drive shaft 221 is at a suitable level.

[0098] Example 3:

[0099] A paper waste collection device, as described above Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that: a switching mechanism 5 is provided on one side of the mounting frame 1. The switching mechanism 5 includes a first rotating disk 51 and a second rotating disk 52. The first rotating disk 51 and the second rotating disk 52 are arranged coaxially, and the first rotating disk 51 is spaced apart from the second rotating disk 52 along its own axial direction. The axial direction of the first rotating disk 51 is parallel to the axial direction of the winding drive shaft 221. The second rotating disk 52 is located on the side of the first rotating disk 51 away from the mounting frame 1 along its own axial direction.

[0100] Reference Figure 6 and Figure 7 The switching mechanism 5 also includes a mounting base 53. Both the first rotating disk 51 and the second rotating disk 52 are rotatably connected to the mounting base 53. A rotating motor 54 is mounted on the mounting base 53, and the output shaft of the rotating motor 54 is connected to the first rotating disk 51. Several connecting rods 55 are provided between the first rotating disk 51 and the second rotating disk 52, with each end of the connecting rod 55 connected to both the first rotating disk 51 and the second rotating disk 52 along its length. Therefore, the first rotating disk 51 and the second rotating disk 52 can rotate synchronously by the drive of the rotating motor 54.

[0101] Reference Figure 6 and Figure 7The first rotating disk 51 is provided with a plurality of connecting shafts 56, which are evenly spaced along the circumference of the first rotating disk 51, and the axial direction of the connecting shafts 56 is parallel to the axial direction of the first rotating disk 51.

[0102] Reference Figure 6 and Figure 7 The first rotating disk 51 has several connecting holes 511, which penetrate the first rotating disk 51 along its axial direction. Each connecting hole 511 corresponds to a connecting shaft 56, and the connecting shaft 56 is inserted into the corresponding connecting hole 511. The connecting shaft 56 is rotatably connected to the inner wall of the corresponding connecting hole 511 or spaced apart from it. Several fixed bearing seats 58 are installed on the side of the first rotating disk 51 facing the second rotating disk 52. Each fixed bearing seat 58 corresponds to a connecting shaft 56, and the fixed bearing seat 58 is inserted into the corresponding connecting shaft 56.

[0103] Therefore, the fixed bearing housing 58 is provided to fix the connecting shaft 56 while ensuring that the connecting shaft 56 can rotate. The connecting hole 511 is provided so that the connecting shaft 56 can pass through the first rotating disk 51 in the direction of the mounting bracket 1.

[0104] Reference Figure 7 and Figure 8 The switching mechanism 5 also includes a magnetic coupling 57, which comprises a first half-coupling 571 and several second half-couplings 572. The first half-coupling 571 is coaxially connected to the winding drive shaft 221 and is located at the end of the winding drive shaft 221 facing the first rotating disk 51 along the axial direction of the winding drive shaft 221. Each second half-coupling 572 corresponds to a connecting shaft 56, and is coaxially connected to the corresponding connecting shaft 56 and is located at the end of the connecting shaft 56 facing the mounting bracket 1 along the axial direction of the corresponding connecting shaft 56.

[0105] During the rotation of the first rotating disk 51, a connecting shaft 56 is coaxially arranged with the winding drive shaft 221. Therefore, when the winding drive shaft 221 and the corresponding connecting shaft 56 are coaxially arranged, the first half-coupling 571 and the corresponding second half-coupling 572 can rotate coaxially, so that the winding drive shaft 221 can drive the corresponding connecting shaft 56 to rotate.

[0106] Reference Figure 1 and Figure 9 Several take-up rollers 21 are provided, and each take-up roller 21 and connecting shaft 56 are provided in a one-to-one correspondence.

[0107] Reference Figure 9 and Figure 10The take-up roller 21 has an insertion hole 214 at one axial end, which penetrates the take-up roller 21 along its axial direction. The insertion hole 214 is inserted into the corresponding connecting shaft 56 along its axial direction. A plurality of locking rods 215 are provided on the inner wall of the insertion hole 214, with their length direction along the axial direction of the insertion hole 214. A plurality of locking grooves 561 are provided on the side wall of the connecting shaft 56, penetrating the side wall of the connecting shaft 56 along its axial direction. The locking rods 215 and locking grooves 561 are arranged in a one-to-one correspondence, and the locking rods 215 are inserted into the corresponding locking grooves 561 along the axial direction of the corresponding connecting shaft 56, while also slidingly connected to the inner wall of the corresponding locking groove 561 along the axial direction of the corresponding connecting shaft 56.

[0108] Therefore, a take-up roller 21 can be installed on each connecting shaft 56, and the locking groove 561 and locking rod 215 can achieve synchronous rotation between the take-up roller 21 and the corresponding connecting shaft 56. Therefore, the switching mechanism 5 can realize the automatic switching of the take-up roller 21.

[0109] Reference Figure 9 and Figure 10 The first limiting plate 212 is located between the second limiting plate 213 and the first rotating plate 51 along its own axial direction, and the first limiting plate 212 is fixedly connected to the roller body 211. The second limiting plate 213 has an installation groove 2131 on one axial side, which is coaxial with the roller body 211 and is inserted into the roller body 211 along the axial direction.

[0110] Therefore, by opening the mounting groove 2131, the second limiting plate 213 can be detachably connected to the shaft, making it easy to remove the second limiting plate 213 from the shaft, thereby making it easy to remove the waste paper wound by the winding roller 21 from the winding roller 21.

[0111] Reference Figure 5 and Figure 6 The second rotating disk 52 is provided with a plurality of fixing holes 521. The fixing holes 521 penetrate the second rotating disk 52 along the axial direction of the second rotating disk 52. The fixing holes 521 and the connecting holes 511 are provided one-to-one. The fixing holes 521 and the corresponding connecting holes 511 are arranged coaxially.

[0112] Reference Figure 5 and Figure 9A fixing rod 562 is coaxially mounted on the end of the connecting shaft 56 away from the mounting bracket 1 along its own axial direction. The fixing rod 562 is inserted into the corresponding fixing hole 521, and the side wall of the fixing rod 562 and the inner wall of the fixing hole 521 are spaced apart from each other. A support seat 522 is inserted into the fixing hole 521, and the support seat 522 is rotatably connected to the inner wall of the fixing hole 521. A threaded hole 5221 is provided through the support seat 522, and the support seat 522 is coaxially connected to the corresponding fixing rod 562. The threaded hole 5221 is inserted into the corresponding fixing rod 562, and the inner wall of the threaded hole 5221 is connected to the fixing rod 562 by threads. The side of the support seat 522 facing the first rotating disk 51 along the axial direction of the fixing rod 562 abuts against the second limiting disk 213.

[0113] Therefore, during the rotation of the connecting shaft 56, the cooperation between the support base 522 and the fixing rod 562 can support the end of the connecting shaft 56 away from the mounting frame 1, thereby improving the stability of the rotation of the connecting shaft 56. At the same time, since the support base 522 abuts against the second limiting plate 213, the installation stability between the second limiting plate 213 and the roller body 211 can be improved.

[0114] Reference Figure 10 and Figure 11 A cutting mechanism 6 is provided on the first limiting plate 212. The cutting mechanism 6 includes a cutting groove 61, which is opened on the side of the first limiting plate 212 facing the second limiting plate 213. The length direction of the cutting groove 61 is arranged radially along the first limiting plate 212. A cutting plate 62 is inserted into the cutting groove 61. The length direction of the cutting plate 62 is parallel to the axial direction of the roller body 211. One end of the cutting plate 62 is inserted into the cutting groove 61 and slides along the length direction of the cutting groove 61 to the inner wall of the cutting groove 61.

[0115] Reference Figure 10 and Figure 11 A cutting drive 63 is provided on the side of the cutting plate 62 away from the roller body 211. The cutting drive 63 is installed on the inner wall of the cutting groove 61. The cutting drive 63 includes a driving electromagnet 631 and a return spring 632. The driving electromagnet 631 is arranged at intervals with the cutting plate 62 along the length direction of the cutting groove 61. The return spring 632 is arranged axially along the length direction of the cutting groove 61. The two ends of the return spring 632 are respectively connected to the driving electromagnet 631 and the cutting plate 62. The cutting plate 62 is made of a magnet or a material that can be attracted by a magnet.

[0116] Reference Figure 10 and Figure 11 The cutting mechanism 6, through the setting of the cutting drive 63, can drive the cutting plate 62 to move toward the roller 211, thereby cutting the waste paper strip passing over the upper side of the roller 211, and fixing one end of the waste paper strip to the roller 211.

[0117] The implementation principle of this application embodiment is as follows: when the winding roller 21 is in working state, the magnetic coupling 57 will drive the winding roller 21 to rotate to realize the winding of waste paper.

[0118] Since the waste paper strip wound by the old take-up roller 21 will pass outside the new take-up roller 21, the guide arm 33 will drive the waste paper strip to move on the new take-up roller 21. Therefore, when the new take-up roller 21 is determined to be replaced, at the instant when the waste paper strip moves to the gap between the cutter plate 62 and the roller body 211, the drive electromagnet 631 is de-energized, and the return spring 632 pushes the cutter plate 62 to move towards the roller body 211. At this time, the cutter plate 62 cuts the waste paper strip and fixes one end of the waste paper strip to the new take-up roller 21. At this time, the cutting mechanism 6 rotates, and the new take-up roller 21 moves to be coaxial with the take-up drive shaft 221. The magnetic coupling 57 realizes the coaxial rotation between the new take-up roller 21 and the take-up drive roller.

[0119] After the switch is completed, the support base 522 corresponding to the old take-up roller 21 is removed, so that the old take-up roller 21 can be pulled out and replaced with a new take-up roller 21.

[0120] With this setup, the waste paper tape does not need to be stopped or only needs to be briefly stopped during the process of changing the take-up roller 21.

[0121] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
