Description

Technical Field

[0001] This invention relates to the technical field of material receiving devices, and specifically to a vertical material receiving device for multi-disc spring sheet strips. Background Technology

[0002] Spring contacts in electronic components are formed by stamping from strip material. These spring contacts are produced, transported, and assembled as continuous strips. The receiving device typically uses a receiving tray, which is driven by a motor to rotate, causing the strip material to wind onto the tray. During operation, the end of the strip needs to be fixed to the receiving tray, and a new receiving tray is replaced when it is full. When multiple receiving trays are used, usually one tray is in operation while the others can be switched, allowing for faster switching between trays and reducing downtime.

[0003] Chinese patent CN218370717U discloses a vertical multi-disc receiving mechanism with detection function, including a feeding device, a receiving device connected to the feeding device, a material changing device for driving the receiving device, and an electrical control box. A buffer device is provided at the front end of the feeding device. The feeding device includes a feeding channel, limiting blocks on both sides of the feeding channel, a feeding pressure roller mechanism on the feeding channel for pressing and transferring material, and a vision detection mechanism beside the feeding channel. The buffer device includes a linear longitudinal movement module. The first guide roller and several cooperating guide rollers are included. The receiving device includes a receiving rack, a paper tape reel located at the upper end of the receiving rack, a receiving tray located at the lower end of the receiving rack, and a receiving motor for driving the receiving tray to rotate and receive the paper tape. A paper tape detection component is also installed on the receiving rack, which includes a paper tape guide roller, a torque controller for adjusting the paper tape tension, and an Omron proximity switch located above the guide roller. A cutting device is located at the rear of the feeding device, which includes a punching cylinder, a punching blade driven by the punching cylinder, and a receiving tray. Several sets of paper tape reels are arranged side by side at the upper end of the receiving rack, and the same number of receiving trays are arranged at the lower end of the receiving rack. The material changing device includes a moving plate located at the bottom of the receiving device and a drive device for moving the moving plate. The drive device moves the moving plate, and every time it moves a certain distance, the feeding channel corresponds to a set of receiving trays, thereby realizing material changing.

[0004] After passing through the paper tape detection component, the paper tape on the paper tape reel needs to be wound onto the take-up tray. When the take-up tray winds the tape, it forms a loop of paper tape and a loop of material tape. On the one hand, the paper tape can separate the two loops of material tape, ensuring that the material tape can be released smoothly in subsequent use. On the other hand, the paper tape can clamp the end of the material tape between the two layers of paper tape so that the material tape can be smoothly wound onto the take-up tray. However, when the take-up tray is replaced, the end of the paper tape needs to be fixed to the inner wall of the take-up tray with tape so that the paper tape can be automatically wound onto the take-up tray when the take-up tray rotates. Because the gap inside the take-up tray is small, it is difficult for the operator to insert their hand into the take-up tray, making the operation of fixing the paper tape with tape very difficult. Summary of the Invention

[0005] This invention provides a vertical take-up device for multi-reel spring sheet paper strips, which aims to solve the problem of how to conveniently connect the ends of the paper strips to the periphery of the take-up reel.

[0006] The present invention provides a multi-reel spring sheet strip vertical take-up device, comprising a base, a feeding mechanism and a winding mechanism disposed on the base, wherein the winding mechanism is movable in the horizontal direction to dock with the feeding mechanism, the winding mechanism includes a plurality of strip winding frames for mounting take-up reels, the strip winding frame includes a material rack and a winding assembly, a material shaft driven by the winding assembly is rotatably disposed on the material rack, and the take-up reels are mounted on the material shaft;

[0007] The material rack is also equipped with a paper tape fixing assembly, which is used to press the end of the paper tape tightly and to wrap the paper tape around the inner peripheral wall of the receiving tray as it rotates.

[0008] The paper tape fixing assembly includes:

[0009] A rotating arm is rotatably mounted on the material rack. The rotation axis of the rotating arm on the material rack coincides with the center line of the material shaft. The rotating arm rotates from the starting position to the ending position with the receiving tray.

[0010] An inner extension rod connected to the rotating arm is capable of extending into the interior of the receiving tray;

[0011] And a roller located at the end of the inner extension rod is rotated to press the paper tape against the inner circumferential wall of the take-up tray; when the rotating arm reaches the end position, the roller rolls relative to the take-up tray to complete the paper tape winding.

[0012] Its effect is as follows: through the coordinated operation of the rotating arm, the inner extension rod, and the rollers, the end of the paper tape is pressed firmly against the inner wall of the take-up tray. At this time, the take-up tray can rotate under the drive of the winding assembly. The take-up tray and the rotating arm rotate simultaneously, and the paper tape begins to complete the initial winding. After the rotating arm rotates from the starting position to the ending position, the paper tape continues to be pressed by the rollers. At the same time, the rollers cooperate with the rotation of the take-up tray, so that the paper tape completes the winding while the rollers and the take-up tray are rolling. There is no need for the operator to insert their hand into the take-up tray, thus facilitating the fixing of the end of the paper tape. In the scenario of multi-reel take-up, the winding mechanism can move horizontally and seamlessly connect with the feeding mechanism, while the paper tape fixing assembly can quickly fix the end of the paper tape to the take-up tray. When one take-up tray is full, the winding mechanism can quickly switch to the next take-up tray. The rotation axis of the rotating arm coincides with the center line of the material shaft, ensuring that the pressure applied by the roller is always uniform. The movement trajectory of the rotating arm is synchronized with the rotation of the receiving tray. From the starting position to the ending position, the rotating arm completes the fixing and initial winding of the paper tape.

[0013] Meanwhile, the device effectively reduces reliance on operator skills and improves operational safety. The automated, fixed process replaces manual hand-insertion into the receiving tray, avoiding potential safety hazards.

[0014] Preferably, the rotating arm is provided with a locking device for locking the rotating arm and the receiving tray to rotate synchronously; a connecting block is installed at the end of the rotating arm away from the roller, and the locking device includes a locking plate slidably disposed on the connecting block and a first spring for pressing the locking plate against the peripheral wall of the receiving tray.

[0015] Its effect is as follows: the locking device, through the preload of the first spring, presses the locking plate against the circumferential wall of the take-up tray with a constant and reliable pressure, achieving a secure connection between the rotating arm and the take-up tray. From the very first moment of rotation, the rotating arm can rotate synchronously with the take-up tray. This slip-free synchronous movement ensures that the rollers can wrap the end of the paper tape around the take-up tray at the same linear velocity as the inner wall of the take-up tray, preventing the end of the paper tape from falling off.

[0016] Preferably, the locker further includes a sliding sleeve and a locking pin. The sliding sleeve is slidably connected to the connecting block, and the inner extension rod is slidably fitted inside the sliding sleeve. One end of the first spring is fixed to the sliding sleeve, and the other end is fixed to the locking plate. The locking pin is disposed on the side wall of the sliding sleeve perpendicular to the sliding direction of the sliding sleeve. When the locking pin extends out of the side wall of the sliding sleeve, the locker is in a locked state of the rotating arm and the receiving tray. A clearance groove is provided on the side wall of the inner extension rod. When the paper tape wound on the receiving tray pushes the inner extension rod to move, the locking pin on the locker enters the clearance groove, thereby unlocking the locker.

[0017] Its effect is as follows: as the paper tape begins to wind layer by layer, the increase in its thickness pushes the inner extension rod to shift. When the displacement reaches the point where the locking pin aligns with the clearance groove, the locking device unlocks instantly and precisely. If the locking device unlocks too early, the beginning end of the paper tape may not be fully secured; if it unlocks too late, continuous rolling will damage the already wound tape. Once the locking pin enters the clearance groove, the rotating arm, inner extension rod, and rollers can smoothly retract to a non-interfering state, completely releasing the subsequent winding space to the tape.

[0018] Preferably, a stop block is fixedly provided on the material rack, which is used to stop the rotating arm at the end position; a torsion spring is provided between the rotating arm and the material rack, which is used to drive the rotating arm to rotate towards the starting position.

[0019] Its effect is as follows: the stop block sets the end position for the working stroke of the rotating arm, ensuring that the material strip can wind smoothly during the process of the roller and the take-up tray clamping the strip. The force resisted by the torsion spring when the rotating arm passively rotates with the take-up tray is converted into its own elastic potential energy and stored. When the lock is unlocked, the torsion spring releases energy, driving the rotating arm to return to the starting position for easy use next time.

[0020] Preferably, a second spring is sleeved on the inner extension rod, one end of the second spring is fixed to the locking plate, and the other end is fixed to the inner extension rod, and the elastic force of the second spring is less than that of the first spring.

[0021] Its effect is as follows: when the paper tape winds and pushes the inner extension rod, the second spring is compressed first. The first spring is mainly responsible for providing the locking plate with the clamping force on the take-up tray to ensure synchronous rotation; while the second spring is responsible for sensing the pushing force of the paper tape and converting it into the displacement of the inner extension rod, driving the unlocking mechanism. Through the difference in elasticity between the first and second springs, the minimum paper tape thickness required for unlocking can be accurately controlled.

[0022] Preferably, the feeding mechanism includes a mounting frame, a rotating head, a connecting rod, and a linear drive module. The mounting frame is connected to the base, the rotating head is rotatably connected to the mounting frame and the rotation axis is horizontally set, the linear drive module is fixed on the mounting frame, one end of the connecting rod is rotatably connected to the rotating head, and the other end is mounted on the linear drive module. The rotating head is provided with a feeding channel, and the linear drive module is used to drive the rotating head to rotate so as to adjust the angle of the feeding channel.

[0023] Its effect is that the linear drive module drives the connecting rod, thereby controlling the rotation of the rotating head. In this way, the linkage between the rotating head and the linear drive module realizes the adjustment of the angle of the feeding channel. The angle of the feeding channel can be matched with the radius of the material strip winding on the receiving tray, so as to avoid damage caused by the material strip turning at a large angle at the end of the feeding channel.

[0024] Preferably, the rotating head is provided with an encoder wheel, a conveyor wheel, and a punching blade. The encoder wheel, conveyor wheel, punching blade, and feeding channel are arranged sequentially along the conveying direction of the material belt, and the encoder wheel is connected to an encoder.

[0025] Preferably, the base is provided with a lifting mechanism, which includes a stand, a linear guide rail and a lifting screw. The stand is fixed on the base, the mounting bracket is vertically slidably connected to the stand through the linear guide rail, and the lifting screw is rotatably mounted on the stand and threadedly connected to the mounting bracket.

[0026] Preferably, the winding mechanism further includes a paper tape unwinding frame and a paper tape driving assembly. The paper tape unwinding frame is used to install the paper tape reel, and the paper tape driving assembly includes an active roller and a driven roller for clamping and conveying the paper tape, a tensioning wheel for adjusting the tension of the paper tape, and a paper tape tension sensor for detecting the tension of the paper tape.

[0027] Its effect is that the paper belt drive assembly achieves precise control of the paper belt tension. The coordinated work of the drive roller and the driven roller can pull the paper belt forward at a constant speed. The tensioning wheel can fine-tune the tension of the paper belt by adjusting its position or applying additional tension, thereby ensuring the tightness of the paper belt's winding with the feed belt.

[0028] Preferably, the winding assembly includes a winding motor, a drive pulley connected to the output shaft of the winding motor, a driven pulley connected to the material shaft, and a transmission belt connecting the drive pulley and the driven pulley.

[0029] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0030] In this invention, the take-up reel rotates under the drive of the winding assembly. The take-up reel and the rotating arm rotate simultaneously, initiating the initial winding of the paper tape. After the rotating arm rotates from the starting position to the ending position, the paper tape continues to be pressed by the rollers. Simultaneously, the rollers, in conjunction with the rotation of the take-up reel, ensure the paper tape is wound while the rollers and take-up reel are rolling, eliminating the need for operators to insert their hands into the take-up reel, thus facilitating the fixing of the paper tape ends. When one take-up reel is full, the winding mechanism can quickly switch to the next take-up reel. The rotation axis of the rotating arm coincides with the center line of the material shaft, ensuring that the pressure applied by the rollers is always uniform. The movement trajectory of the rotating arm is synchronized with the rotation of the take-up reel. From the starting position to the ending position, the rotating arm completes the fixing and initial winding of the paper tape. The stop block sets the end position for the working stroke of the rotating arm, ensuring that the paper tape can wind smoothly during the winding process between the rollers and the take-up reel. The force resisted by the torsion spring when the rotating arm passively rotates with the take-up reel is converted into its own elastic potential energy and stored. Attached Figure Description

[0046] The following is combined Figures 1 to 13 Embodiments of the present invention will be described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] This embodiment discloses a vertical receiving device for multi-disc spring sheet material strips, such as... Figure 1 and Figure 2 As shown, the device includes a base 1, a feeding mechanism 2, a winding mechanism, and a moving mechanism 3. The feeding mechanism 2 and the moving mechanism 3 are mounted on the base 1. The winding mechanism moves horizontally via the moving mechanism 3. The feeding mechanism 2 and the winding mechanism are arranged sequentially along the conveying direction of the material belt. The moving mechanism 3 moves perpendicular to the conveying direction of the material belt. Multiple take-up trays 4 are mounted on the winding mechanism. The multiple take-up trays 4 are arranged sequentially along the driving direction of the moving mechanism 3, so that each of the multiple take-up trays 4 corresponds to the feeding mechanism 2. Thus, the material belt is conveyed from the feeding mechanism 2 to the take-up trays 4 and wound up by the take-up trays 4.

[0048] refer to Figure 2The feeding mechanism 2 is mounted on the base 1 via the lifting mechanism 5. The lifting mechanism 5 includes a frame 51, a linear guide rail, and a lifting screw 52. The frame 51 is vertically fixed on the upper surface of the base 1. The linear guide rail is installed between the frame 51 and the feeding mechanism 2. The lifting screw 52 is vertically set and rotatably mounted on the frame 51. The lifting screw 52 is connected to the feeding mechanism 2. The feeding mechanism 2 is vertically slidably connected to the frame 51 via the linear guide rail. The height of the feeding mechanism 2 can be adjusted by rotating the lifting screw 52, ​​thereby enabling the feeding mechanism 2 to adapt to the conveying of material belts at different height positions, so as to adapt to different receiving trays 4.

[0049] refer to Figure 3 The feeding mechanism 2 includes a mounting frame 21, a rotating head 22, a connecting rod 23, and a linear drive module 24. The mounting frame 21 is connected to the upright frame 51 via a linear guide rail and is threadedly connected to the lifting screw 52. A rotating shaft 25 is mounted on the mounting frame 21, and the rotating head 22 is rotatably connected to the mounting frame 21 via the rotating shaft 25. The rotating shaft 25 is horizontally positioned and perpendicular to the conveying direction of the material belt. One end of the connecting rod 23 is rotatably connected to the rotating head 22, and the other end is mounted on the moving part of the linear drive module 24. The linear drive module 24 is horizontally positioned and fixed on the mounting frame 21. The driving direction of the linear drive module 24 is perpendicular to the rotating shaft 25. The linear drive module 24 pushes one end of the connecting rod 23, causing the other end of the connecting rod 23 to drive the rotating head 22 to rotate vertically around the rotating shaft 25. A feeding channel 26 extending along the conveying direction of the material belt is fixedly provided on the rotary head 22. The end of the feeding channel 26 away from the rotary head 22 extends to the take-up tray 4. When the rotary head 22 rotates vertically, the end of the feeding channel 26 near the take-up tray 4 moves up and down to adjust the angle of the feeding channel 26 so that the feeding channel 26 is always tangent to the wound material belt on the take-up tray 4, thereby reducing the deformation of the material belt at the end of the feeding channel 26.

[0050] The rotary head 22 is also equipped with an encoder wheel 221, a conveyor wheel 222, and a punching blade 223. These components, along with the feeding channel 26, are arranged sequentially along the conveying direction of the material belt. The encoder wheel 221 is mounted on the rotary head 22 via an encoder to detect the conveying speed of the material belt. The conveyor wheel 222 is connected to a motor, which drives it to rotate. The conveyor wheel 222 is rotatably mounted on the rotary head 22. A clamping wheel 224 is correspondingly positioned above the conveyor wheel 222. The clamping wheel 224 moves up and down via a cylinder, engaging with the conveyor wheel 222 to clamp the material belt. The rotation of the conveyor wheel 222 actively conveys the material belt. The punching blade 223 is connected to a cylinder or hydraulic cylinder fixed on the mounting frame 21, allowing it to move vertically towards the material belt to cut it. In use, the conveyor wheel 222 actively conveys the material belt, and the encoder wheel 221 rolls with the material belt and detects the conveying speed through the encoder. When the take-up disc 4 completes the take-up of a roll, the punch cutter 223 cuts the material belt to complete the automatic material cutting.

[0051] refer to Figure 4 The winding mechanism includes a frame 64 and multiple tape winding frames 61, paper tape unwinding frames 62, and a paper tape drive assembly 63 mounted on the frame 64. The frame 64 is horizontally slidably connected to the base 1 via a set of linear guide rails. The sliding direction of the frame 64 on the base 1 is horizontal and perpendicular to the tape conveying direction. The moving mechanism 3 includes a drive motor 31 and a drive screw 32. The drive motor 31 is fixed to the base 1, and the drive screw 32 is rotatably mounted on the base 1 and connected to the output shaft of the drive motor 31 via a coupling. The drive screw 32 is arranged parallel to the linear guide rails. The number of tape winding frames 61 and paper tape unwinding frames 62 is the same; in this embodiment, four are selected, but five or six can also be used. Each tape winding frame 61 corresponds to one paper tape unwinding frame 62, and the multiple tape winding frames 61 are arranged sequentially along the moving direction of the frame 64. The tape take-up rack 61 is used to install the take-up reel 4, and the paper tape unwind rack 62 is used to install the paper tape reel. The paper tape reel newly installed on the paper tape unwind rack 62 contains paper tape. In use, the paper tape reel on the paper tape unwind rack 62 is unwound by the paper tape drive assembly 63, causing the paper tape to wind onto the take-up reel 4. When one take-up reel 4 finishes winding the tape, the tape is automatically cut by the punch cutter 223. Then, the drive motor 31 drives the drive screw 32 to rotate, causing the drive screw 32 to horizontally move the winding mechanism between two adjacent tape take-up racks 61, so that the other tape take-up rack 61 corresponds to the feeding channel 26. One end of the paper tape has been wound more than once on the take-up reel 4. At this time, the tape that actively enters the take-up reel 4 through the feeding channel 26 will enter between the two layers of paper tape. As the take-up reel 4 rotates, the tape will be automatically wound onto the take-up reel 4.

[0052] refer to Figure 5 and Figure 6 The paper tape unwinding frame 62 includes a fixed shaft 621, mounting arms 622, and mounting shaft 623. The fixed shaft 621 is fixedly mounted on the frame 64. Multiple mounting arms 622 of the paper tape unwinding frames 62 are arranged sequentially along the fixed shaft 621 and located on the same fixed shaft 621. One end of each mounting arm 622 is connected to the fixed shaft 621, and the other end is used to rotatably mount the mounting shaft 623. The mounting shaft 623 is used to mount the paper tape reel, which can rotate on the mounting arm 622 via the mounting shaft 623. A stop block 624 is also fixedly mounted on the frame 64. The stop block 624 is located on one side of the mounting arm 622. When the mounting arm 622 rotates to abut against the stop block 624, the mounting shaft 623 is on the side of the fixed shaft 621 where the stop block 624 is located, thus allowing the paper tape reel to be unwound stably.

[0053] refer to Figure 6 The paper tape drive assembly 63 is located below the paper tape reel. The paper tape drive assembly 63 pulls the paper tape downwards for unwinding. The paper tape drive assembly 63 includes a drive roller 631 and a driven roller 632. A mounting plate 633 is fixedly mounted on the frame 64. The drive roller 631 is rotatably mounted on the mounting plate 633 and is connected to a motor. The motor is a servo motor, and its speed is the same as the speed of the paper tape detected by the encoder, ensuring that the feeding speed of the paper tape equals the unwinding speed, facilitating the tightening of the paper tape on the take-up reel 4. The driven roller 632 is located below the drive roller 631 and is connected to a moving part 634. The moving part 634 is a hydraulic cylinder or a pneumatic cylinder, fixed to the mounting plate 633. The moving part 634 is used to move the driven roller 632 up and down, allowing the driven roller 632 to cooperate with the drive roller 631 to clamp the paper tape. The mounting plate 633 is also equipped with a first guide wheel 635, a second guide wheel 636, and a third guide wheel 637. A tensioning wheel 638 is positioned between the first guide wheel 635 and the second guide wheel 636, and a paper belt tension sensor 639 is positioned between the second guide wheel 636 and the third guide wheel 637. The paper belt passes sequentially over the drive roller 631, the first guide wheel 635, the tensioning wheel 638, the second guide wheel 636, the paper belt tension sensor 639, and the third guide wheel 637. The tensioning wheel 638 is used to adjust the tension of the paper belt to ensure that the paper belt is wound with the material belt at the appropriate tension. When the paper belt tension sensor 639 detects insufficient tension in the paper belt, the tension of the paper belt can be increased by slowing down the rotation speed of the drive roller 631 or adjusting the position of the tensioning wheel 638.

[0054] refer to Figure 7 and Figure 8The strip take-up frame 61 includes a strip rack 611 and a take-up assembly 612. A connecting shaft 613 is fixedly mounted on the frame 64. Each strip rack 611 has a sleeve 614 fixedly mounted at its end. A strip shaft 615 for mounting the take-up reel 4 is rotatably mounted at the end away from the sleeve 614. The strip shaft 615 is driven to rotate by the take-up assembly 612, and the take-up reel 4 rotates under the drive of the strip shaft 615. A damping block 616 is sleeved on the connecting shaft 613. The damping block 616 is positioned between the two sleeves 614 and is deformed by the compression of the two sleeves 614, creating friction between the damping block 616 and the ends of the sleeves 614. The sleeves 614 are rotatably connected to the connecting shaft 613 via bearings. A positioning block 617 is fixedly installed on the frame 64. The positioning block 617 is located on one side of the connecting shaft 613, and the material rack 611 is tilted after contacting the positioning block 617 during rotation. The take-up tray 4 is located on the side of the connecting shaft 613 where the positioning block 617 is located. When it is necessary to replace the take-up tray 4, the material rack 611 can be rotated to move the material rack 611 away from the positioning block 617 and stagger it from the take-up trays 4 of other normally wound material strips, thus making the installation of the take-up tray 4 more convenient. At the same time, the damping block 616 can control the rotation speed of the material rack 611 to prevent the material rack 611 from rotating too fast under the action of gravity during the operation of the operator.

[0055] refer to Figure 9 The winding assembly 612 includes a winding motor 6121, a drive pulley 6122, a driven pulley 6123, and a drive belt 6124. The drive pulley 6122 is coaxially fixed on the output shaft of the winding motor 6121. The winding motor 6121 is fixedly mounted on the material rack 611 and located at one end of the material rack 611 near the connecting shaft 613. The driven pulley 6123 is coaxially fixed on the material shaft 615. The driven pulley 6123 and the drive pulley 6122 are connected by the drive belt 6124. The material rack 611 has a hollow structure, and the drive pulley 6122, driven pulley 6123, and drive belt 6124 are all located inside the material rack 611. The winding motor 6121, drive pulley 6122, drive belt 6124, and driven pulley 6123 can drive the material shaft 615 to rotate, thereby causing the take-up reel 4 to rotate for winding the material strip.

[0056] refer to Figure 9 and Figure 10A paper tape fixing assembly 7 is installed on the material rack 611. The paper tape fixing assembly 7 is used to press the end of the paper tape against the inner peripheral wall of the take-up tray 4 and to complete the winding of the end of the paper tape around the take-up tray 4 at least once. The paper tape fixing assembly 7 includes a rotating arm 71, an inner extension rod 72, and a roller 73. One end of the rotating arm 71 is rotatably mounted on the material rack 611, and the rotation axis of the rotating arm 71 relative to the material rack 611 coincides with the rotation axis of the material shaft 615; alternatively, the rotating arm 71 can be rotatably connected to the material shaft 615. One end of the inner extension rod 72 is rotatably mounted with the roller 73, and the other end is located at the end of the rotating arm 71 away from the material shaft 615. The connection point between the inner extension rod 72 and the rotating arm 71 is located outside the take-up tray 4, allowing the inner extension rod 72 to be inserted into the interior of the take-up tray 4 from the edge of the take-up tray 4. When it is necessary to fix the paper tape to a new take-up tray 4, the operator inserts the end of the inner extension rod 72 with the roller 73 into the take-up tray 4, so that the roller 73 clamps the end of the paper tape against the inner peripheral wall of the take-up tray 4. Then the take-up tray 4 rotates, and the rotating arm 71 rotates simultaneously with the take-up tray 4. The endpoint of the rotation of the rotating arm 71 should be in the upper half of the take-up tray 4. During this process, the paper tape is subjected to the frictional force of the take-up tray 4, and the roller 73 does not rotate. Then, after the rotating arm 71 stops, the take-up tray 4 continues to rotate. At this time, the paper tape continues to be wound up with the take-up tray 4 under the frictional force of the take-up tray 4, while the roller 73 rolls on the inner peripheral wall of the rotating arm 71 and maintains the compression of the paper tape. The outer wall of the roller 73 is made of rubber material to increase friction.

[0057] refer to Figure 11 A stop block 74 is fixedly installed on the material rack 611. When the rotating arm 71 rotates with the take-up tray 4 until it abuts against the stop block 74, the rotating arm 71 stops rotating. This is the end position of the rotating arm 71. The starting position of the rotating arm 71 is on the other side of the material shaft 615 where the stop block 74 is installed and is in an inclined upward position. Therefore, the rotation angle of the rotating arm 71 from the starting position to the end position should be greater than 180 degrees, which can be selected as 250 degrees. After the paper tape is finished winding on the take-up tray 4, the paper tape fixing assembly 7 releases the paper tape and returns to the starting position.

[0058] refer to Figure 12 and Figure 13A torsion spring 75 is provided at the end of the rotating arm 71 connected to the material rack 611. One end of the torsion spring 75 is fixed to the rotating arm 71, and the other end is fixed to the material rack 611. The torsion spring 75 is used to drive the rotating arm 71 back to the starting position. A connecting block 77 is provided at the end of the rotating arm 71 away from the material shaft 615. The connecting block 77 is rotatably mounted on the rotating arm 71, and the axis of rotation of the connecting block 77 on the rotating arm 71 is parallel to the axis of the material shaft 615. A locking device 76 is slidably mounted on the connecting block 77. The locking device 76 is used to lock the rotating arm 71 and the receiving tray 4, so that the rotating arm 71 and the receiving tray 4 rotate simultaneously. After the locking device 76 is unlocked, the rotating arm 71 returns to the starting position through the torsion spring 75. In order to reduce the maximum elastic force of the torsion spring 75 so that the locking device 76 requires a smaller force to lock the rotating arm 71 and the receiving tray 4, both the rotating arm 71 and the inner extension rod 72 need to be made of plastic. The locking device 76 includes a sliding sleeve 761, a locking pin 762, a locking plate 763, a first spring 764, and a second spring 765. A guide hole 766 is provided on the connecting block 77, parallel to the inner extension rod 72. The sliding sleeve 761 is slidably fitted within the guide hole 766, and the inner extension rod 72 is slidably disposed within the sliding sleeve 761. The locking pin 762 is located on the side wall of the sliding sleeve 761, slidably connected to the sliding sleeve 761, and its sliding direction is perpendicular to the inner extension rod 72. When one end of the locking pin 762 extends out of the sliding sleeve 761, the end of the locking pin 762 blocks one end of the guide hole 766, preventing the sliding sleeve 761 from moving away from the center of the receiving tray 4. The first spring 764 is located between the sliding sleeve 761 and the locking plate 763, with one end of the first spring 764 fixed to the sliding sleeve 761 and the other end fixed to the locking plate 763. When the locking pin 762 extends, the first spring 764 is in a contracted state and exerts a spring force on the locking plate 763. The locking plate 763 is sleeved on the inner extension rod 72. The width of the locking plate 763 is greater than the thickness of the take-up tray 4, so that the locking plate 763 abuts against the side wall of the outer edge of the take-up tray 4. The locking plate 763 can be selected as an arc shape adapted to the take-up tray 4. Since the spring force of the first spring 764 is sufficient to keep the take-up tray 4 locked to the rotating arm 71, the rotating arm 71 can rotate with the take-up tray 4 until the rotating arm 71 abuts against the stop block 74. At this point, the locking plate 763 will rub against the edge of the take-up tray 4, causing the take-up tray 4 to continue rotating relative to the rotating arm 71. To reduce the friction of the locking plate 763 on the take-up tray 4, the locking plate 763 can be made of a material with a low coefficient of friction, such as nylon.

[0059] The second spring 765 is sleeved on the inner extension rod 72, with one end fixed to the locking plate 763 and the other end fixed to the inner extension rod 72. The elastic coefficient of the second spring 765 is less than that of the first spring 764. When the inner extension rod 72 compresses the paper tape, the second spring 765 is in a contracted state, and its elastic force is used to maintain the tendency of the roller 73 on the inner extension rod 72 to move towards the center of the take-up tray 4. A clearance groove 767 is provided on the inner extension rod 72 for retracting the extended locking pin 762. The clearance groove 767 is provided on the side wall of the inner extension rod 72 opposite to the locking pin 762. When the roller 73 on the inner extension rod 72 abuts against the paper tape, the clearance groove 767 is misaligned with the locking pin 762, and the misalignment distance can be selected as 0.2-0.35mm. When the paper tape is wound onto the take-up tray 4, the paper tape can push the inner extension rod 72 away from the center of the take-up tray 4, causing the clearance groove 767 to move towards the position corresponding to the locking pin 762. A compression spring 768 is fitted on the locking pin 762, with one end of the compression spring 768 abutting against the locking pin 762, giving the locking pin 762 a tendency to move towards the inner extension rod 72. During the paper tape winding process, the second spring 765 is further compressed by abutting against the inner extension rod 72 until the locking pin 762 can enter the clearance groove 767, at which point the second spring 765 reaches its maximum compression. It is important to note that the elastic force of the second spring 765 at its maximum compression is still less than the elastic force of the first spring 764 at its minimum compression, meaning that the locking plate 763 remains stationary while the inner extension rod 72 is pushed by the roller 73. When the locking pin 762 enters the relief groove 767 under the force of the compression spring 768, the locking pin 762 releases its lock on the sliding sleeve 761 and is in an unlocked state. At this time, the locking plate 763 no longer presses against the edge of the take-up tray 4, so the rotating arm 71 returns to the starting position without the control of the take-up tray 4. A slope 769 is provided at the end of the locking pin 762 near the inner extension rod 72. The slope 769 gradually moves away from the inner extension rod 72 along the direction away from the center of the take-up tray 4. When fixing the end of the paper tape, the end of the inner extension rod 72 can be directly pressed, so that the inner extension rod 72 automatically presses against the slope 769 through the edge of the relief groove 767, thereby pushing out the locking pin 762.

[0060] The working process of this embodiment is as follows: When replacing the take-up reel 4, the drive motor 31 drives the drive screw 32, causing the frame 64 to move horizontally under the action of the drive screw 32. This allows another tape take-up frame 61 to connect with the feeding channel 26. The take-up reel 4 that has completed winding is replaced manually. At this time, the material rack 611 is rotated to offset the take-up reel 4 from other take-up reels 4, and it is removed from the material shaft 615 and replaced with a new take-up reel 4. The rotating arm 71 is lifted upwards, causing the rotating arm 71 to push the inner extension rod 72 and the sliding sleeve 761 along the radial direction of the take-up reel 4 and towards the center of the take-up reel 4. The locking pin 762 on the sliding sleeve 761 is pushed to the guide hole 766 near one end of the take-up reel 4. Then, the roller 73 on the inner extension rod 72 engages with the inner side wall of the take-up reel 4 to clamp the paper tape. At this time, the clearance groove 767 on the inner extension rod 72 squeezes out the locking pin 762, putting the locking device 76 in a locked state. The take-up assembly 612 starts driving the take-up reel 4 to rotate, causing the take-up reel 4 to simultaneously rotate the locking device 76 and the rotating arm 71. The end of the paper tape begins to wind around the inner peripheral wall of the take-up reel 4 until the rotating arm 71 is blocked by the stop block 74. The length of the paper tape wound exceeds half of the inner peripheral wall of the take-up reel 4. At this point, the take-up reel 4 continues to rotate, the rotating arm 71 stops rotating, and the roller 73 rolls instead. The roller 73 cooperates with the take-up reel 4 to continue winding the paper tape. The locking plate 763 slides relative to the take-up reel 4 until the end of the paper tape is wound more than one turn. Then, the inner extension rod 72 is abutted by the paper tape and opens. The material initially moves radially along the take-up tray 4. The clearance groove 767 on the inner extension rod 72 is aligned with the locking pin 762, at which point the locking device 76 is unlocked. The rotating arm 71 returns to the starting position under the force of the torsion spring 75. However, due to the gravity of the rotating arm 71, the final stopping position of the rotating arm 71 does not reach the starting position. Therefore, the rotating arm 71 is in a horizontal state during the return, while the inner extension rod 72 is in a vertical state under the action of gravity, maximizing the distance between the inner extension rod 72 and the take-up tray 4 to prevent the inner extension rod 72 from affecting the take-up tray 4's winding of the material strip. At this point, the material rack 611 is reset. During the winding process of the take-up tray 4, the end of the feeding channel 26 is first tangent to the inner peripheral wall of the take-up tray 4, allowing the material strip to flow out of the feeding channel 26 and enter the paper strip winding position, so that the two layers of paper strip sandwich the material strip. The take-up tray 4 rotates via the take-up assembly 612, while the paper tape drive assembly 63 unwinds the paper tape, causing the paper tape and material tape to be wound onto the take-up tray 4 simultaneously. As the material roll on the take-up tray 4 gradually increases in size, the linear drive module 24 rotates the rotating head 22 via the connecting rod 23. At this time, the feeding channel 26 continuously lifts upward, ensuring that the extension direction of the feeding channel 26 is always tangent to the wound material roll, until the take-up tray 4 is completed. At this time, the punch cutter 223 cuts the material tape, and the paper tape is subsequently torn by the operator.
