Description

Technical Field

[0001] This utility model relates to an adhesive tape applicator and a buffer paper pad winding device for winding up buffer paper pads. Background Technology

[0002] When packaging heavy items, if the cushioning paper pads used for packaging are insufficient, they are easily flattened. If the cushioning paper pads are excessive, there are certain requirements for the stacking method and quantity of the cushioning paper pads to ensure that the heavy items are well supported and have limited movement in all directions inside the box.

[0003] Existing cushioning paper pad equipment produces cushioning paper pads in segments. These cushioning paper pads do not provide good cushioning during the packing of heavy objects. Furthermore, packers need to manually place the cushioning paper pads into the carton in a certain arrangement to cushion the heavy objects. This method is labor-intensive, and the cushioning effect of manually stacked cushioning paper pads is inconsistent.

[0004] Currently, the cushioning paper rewinding rack can rewind continuous cushioning paper pads into a roll. After the cushioning paper pads are rewound, they need to be wrapped together with tape to prevent them from unraveling.

[0005] The existing methods for wrapping cushioning paper pads with tape after winding are mostly done manually, which is inefficient. Some winding racks equipped with tape-applying devices have also appeared on the market, but the tape adhesion is poor, causing the tape to easily fall off. Moreover, during the winding process and before tape application, the free end of the tape is very easy to detach from the equipment. Operators need to frequently check and reposition the free end of the tape, which has a certain impact on the winding efficiency of the cushioning paper pads.

[0006] Therefore, overcoming the aforementioned technical deficiencies is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide an adhesive tape applicator and a buffer paper pad winding device for winding buffer paper pads, so as to solve at least one of the above-mentioned technical problems.

[0008] According to one aspect of the present invention, an adhesive tape mechanism for winding up a cushioning paper pad is provided, comprising:

[0009] The bearing plate is equipped with a first guide roller;

[0010] A tape clamping component is mounted on a support plate.

[0011] A unidirectional rotating roller has its end located on a support plate, and a first guide roller is located below the roller. The first guide roller is used to guide the tape onto the roller.

[0012] The first driving component can drive the carrier plate to move up and down to stick the tape on the tape pressing component to the cushioning paper pad;

[0013] A cutter, located on the side of the tape clamping component; and

[0014] The second drive component can drive the cutter to move up and down to puncture or cut the tape.

[0015] This utility model's adhesive tape applicator works in conjunction with a cushioning paper pad winding device. The adhesive tape sequentially wraps around the first guide roller and the winding roller, with the adhesive side of the tape adhering to the winding roller. The free end of the tape is located on the tape pressing component. The first guide roller guides the tape to smoothly and tautly wrap around the winding roller. After one roll of cushioning paper pads is wound up, under the action of the first drive component, the support plate drives the tape pressing component to move upward. The tape pressing component pushes the tape upward, thereby adhering the tape to the tail of the cushioning paper pad roll. As the cushioning paper pad winding device restarts for a certain period of time, the tape can be adhered and wound around the outer periphery of the cushioning paper pad roll. Then, the second drive... The component drives the cutter to move upward, piercing or cutting the tape. The cushioning paper pad winding device then winds up the remaining unattached tape on the cushioning paper pad and secures it tightly. The tape wrapping and pasting of one roll of cushioning paper pad is completed. In the tape pasting mechanism of this utility model, during the tape pasting process, the tape pressing component can smoothly paste the tape onto the cushioning paper pad, ensuring the tape's adhesion effect and preventing the cushioning paper pad from unraveling after winding. Moreover, since the winding roller rotates in one direction, it can ensure that the tape wrapped on the winding roller will not fall off during the upward movement of the tape pressing component and will not affect the normal forward conveying of the tape with the cushioning paper pad, thereby ensuring the winding efficiency of the cushioning paper pad.

[0016] In some embodiments, the tape clamping component may include a base, a clamping block, a guide rod, and a spring. The side of the base is disposed on a support plate, the bottom of the guide rod is inserted into the base, the top of the guide rod is inserted into the clamping block, the spring is sleeved on the guide rod, the spring is located between the base and the clamping block, the clamping block is located above the base, and the cutter is located on the side of the clamping block.

[0017] Therefore, during the tape application process, the guide rod and spring installed between the clamping block and the base ensure that the force of the clamping block sticking the tape to the cushioning paper pad is uniform. Moreover, due to the presence of the spring, there is no rigid contact between the clamping block and the cushioning paper pad. The spring can effectively reduce the impact force of the clamping block on the cushioning paper pad, ensuring that the clamping block will not damage the discharge port of the external cushioning paper pad making machine during the tape application process.

[0018] In some embodiments, a second guide roller and a limiting roller may also be included, with the ends of the second guide roller and the limiting roller both disposed on the bearing plate. The second guide roller is located on the side of the pressing block, the pressing block is located between the cutter and the second guide roller, and the limiting roller is located diagonally above the second guide roller, with the bottom of the limiting roller not lower than the top of the pressing block.

[0019] Therefore, the second guide roller can guide the tape to be smoothly conveyed to the pressing block. Since the limiting roller is located diagonally above the second guide roller and the bottom of the limiting roller is not lower than the pressing block, the limiting roller can prevent the tape on the pressing block from sticking up and prevent the tape from sticking to the cushioning paper pad when it is not needed. At the same time, no adhesive will stick to the limiting roller.

[0020] In some embodiments, the winding roller may include a roller body, a one-way bearing, and a shaft portion, with the end of the shaft portion disposed on a bearing plate, the inner ring of the one-way bearing sleeved on the shaft portion, and the roller body sleeved on the outer ring of the one-way bearing.

[0021] Therefore, under the action of the one-way bearing, the roller can only rotate in one direction. That is, the roller can only guide the tape to be conveyed forward with the cushioning paper pad, and the tape cannot be conveyed in the opposite direction. This ensures that the tape wrapped around the roller will not fall off during the upward movement of the tape pressing component and will not affect the normal forward conveying of the tape with the cushioning paper pad.

[0022] In some embodiments, the first driving component may include a motor, a connecting rod, and a driving roller, and the bearing plate is provided with transverse grooves.

[0023] One end of the connecting rod is fixed on the motor shaft, and the end of the driving roller is located on the other end of the connecting rod. The driving roller is housed in the transverse groove, and the axis of the driving roller is parallel to the axis of the motor shaft.

[0024] Therefore, when the motor shaft rotates, the end of the connecting rod connected to the drive roller moves in a circular motion around the motor shaft. The connecting rod drives the drive roller to move in a circular motion around the motor shaft. Since the drive roller is housed in the transverse groove, it can drive the support plate to move up and down. That is, when the motor shaft rotates one revolution, the support plate can move upward to the highest point and return to the initial position. The support plate drives the tape pressing component to move upward to the highest point and return to the initial position simultaneously. When the tape pressing component moves upward to the highest point, it sticks the tape to the buffer paper pad. The first driving component, composed of the motor, connecting rod, and drive roller, cooperates with the transverse groove on the support plate, which can make the support plate move up and down smoothly. Moreover, it can convert the circular motion of the motor shaft into the linear motion of the tape pressing component. There are no additional driving components such as cylinders or linear motors in the longitudinal space, which provides installation space for the support rod that carries the tape roll to be installed below the support plate.

[0025] In some embodiments, the surface of the roller may be knurled.

[0026] Therefore, the knurling on the roller body can further ensure that the tape wrapped around the roller body will not fall off during the upward movement of the tape pressing component and will not affect the normal forward conveying of the tape with the cushioning paper pad.

[0027] In some embodiments, the cutter may have triangular blades arranged at an angle, and the second drive component is an electric push rod, a cylinder, or a linear motor.

[0028] Therefore, an electric push rod, cylinder, or linear motor can drive the cutter to puncture the tape. The triangular blades arranged at an angle on the cutter allow the cutter to puncture the tape with less force. An electric push rod is preferred because it allows the cutter to puncture the tape at a faster speed, thus ensuring that the tape does not wrap the cushioning paper pad more tightly during the puncturing process, and also preventing the cutter from being damaged.

[0029] According to another aspect of the present invention, a cushioning paper pad winding device is provided, including a winding mechanism and an adhesive tape applicator. The adhesive tape clamping component is located below the discharge port of the cushioning paper pad machine used to make cushioning paper pads. The winding mechanism can wind and rewind the cushioning paper pads made by the cushioning paper pad machine.

[0030] This utility model discloses a cushioning paper pad winding device. The tape sequentially wraps around a first guide roller and a winding roller, with the adhesive surface of the tape adhering to the winding roller. The free end of the tape is located on a tape pressing component. The first guide roller guides the tape to smoothly and tautly wrap around the winding roller. Cushioning paper pads produced by the cushioning paper pad machine are fed out through the machine's outlet. The winding mechanism winds and rewinds the continuous cushioning paper pads produced by the machine. When a set length of cushioning paper pad is fed out from the machine's outlet, a cutter component at the outlet cuts the pad. When the winding mechanism is about to complete winding the set length of cushioning paper pad, under the action of the first driving component, the bearing plate drives the tape pressing component to move upward. The tape pressing component pushes the tape upward, thereby adhering the tape to the paper of the cushioning paper pad roll. At the tail end of the pad, after the winding mechanism restarts for a certain period of time, the tape can be pasted and wrapped around the outer circumference of the cushioning paper pad roll. Then, the second drive component drives the cutter to move upward, and the cutter punctures or cuts the tape. The winding mechanism then winds up and tightly wraps the remaining un-pasted tape on the cushioning paper pad roll, and the tape wrapping and pasting of one roll of cushioning paper pad is completed. In the process of pasting the tape, the tape pressing component can smoothly paste the tape onto the cushioning paper pad, ensuring the adhesive effect of the tape and preventing the cushioning paper pad from unraveling after winding. Moreover, since the winding roller rotates in one direction, it can be ensured that the tape wrapped on the winding roller will not fall off during the upward movement of the tape pressing component and will not affect the normal forward conveying of the tape with the cushioning paper pad, thereby ensuring the winding efficiency of the cushioning paper pad.

[0031] In some embodiments, when the first drive component drives the tape pressing component to move upward to its highest point, the distance between the bearing surface of the tape pressing component for carrying the tape and the inner top of the discharge port of the external cushioning paper pad machine for making cushioning paper pads is less than or equal to 15 mm.

[0032] When the tape clamping component applies the tape to the buffer pad in the discharge port of the buffer pad making machine, the top of the buffer pad presses against the inner top of the discharge port of the buffer pad making machine.

[0033] This ensures that the tape clamping component firmly adheres the tape to the cushioning paper pad.

[0034] In some embodiments, the winding mechanism may include a turntable, a winding rod, a pusher plate, a third drive component, and a fourth drive component. The winding rod is disposed on the turntable, the third drive component drives the turntable to rotate, the pusher plate is disposed around the periphery of the turntable, and the fourth drive component can drive the pusher plate to move along the length direction of the winding rod.

[0035] Therefore, when the third drive component drives the turntable to rotate, the rotating winding rod on the turntable will wind up the buffer paper pad. After the winding is completed, under the action of the fourth drive component, the pusher plate moves along the length direction of the winding rod. The pusher plate can push the wound buffer paper pad roll off the winding rod. Then, under the action of the fourth drive component, the pusher plate retracts along the length direction of the winding rod to reset and prepare for the next push.

[0036] In some embodiments, the winding mechanism may further include a crank-connecting rod mechanism, a guide rod, and a mounting plate, with both the third and fourth drive components mounted on the mounting plate.

[0037] One end of the guide rod is mounted on the pusher plate, and the guide rod is inserted into the mounting plate. The guide rod can slide along its length.

[0038] The third drive component is a torque motor.

[0039] The fourth driving component is a motor. The input end of the crank-connecting rod mechanism is located on the rotating shaft of the fourth driving component, and the output end of the crank-connecting rod mechanism is located on the pusher plate.

[0040] Therefore, the mounting plate can support the third drive component, the fourth drive component, the turntable, and the pusher plate. The pusher plate can move smoothly back and forth along the length of the winding rod via the guide rod. When the motor shaft rotates once, the pusher plate can be driven by the crank-connecting rod mechanism to push out the buffer paper pad on the winding rod and retract the pusher plate to its original position. In addition, the tightness of the buffer paper pad roll during the winding process can be adjusted by adjusting the speed of the torque motor and the output speed of the buffer paper pad machine. For example, if the torque motor rotates fast and the output speed of the buffer paper pad machine is slow, the winding of the buffer paper pad roll will be tighter. If the torque motor rotates slowly and the output speed of the buffer paper pad machine is fast, the winding of the buffer paper pad roll will be looser. Attached Figure Description

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0051] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0052] Figures 1 to 4 The diagram schematically illustrates the structure of an adhesive tape mechanism for winding a cushioning paper pad according to one embodiment of the present invention.

[0053] refer to Figures 1 to 4 An adhesive tape applicator for winding cushioning paper pads includes a support plate 1, a tape pressing component 2, a winding roller 3, a first drive component, a cutter 5, and a second drive component 6. Furthermore, the adhesive tape applicator may also include a second guide roller 7, a limiting roller 8, a fixing plate 100, and a mounting frame 200.

[0054] refer to Figures 1 to 3The tape clamping component 2 is mounted on the support plate 1. Specifically, the tape clamping component 2 includes a base 21, a clamping block 22, a guide rod 23, and a spring 24. The side of the base 21 is fixed to the support plate 1. The bottom of the guide rod 23 is inserted into the base 21, and the top of the guide rod 23 is inserted into the clamping block 22. The guide rod 23 can be screwed into the base 21 from the bottom, and the top of the screw extends from the top of the base 21 and is inserted into the receiving hole at the bottom of the clamping block 22. This ensures a stable connection between the guide rod 23 and the base 21. The inner diameter of the receiving hole at the bottom of the clamping block 22 is larger than the outer diameter of the screw. The spring 24 is sleeved on the guide rod 23. The spring 24 is located between the base 21 and the clamping block 22. Between the clamping blocks 22, the clamping block 22 is located above the base 21. The free end of the clamping block 22 is used to support the tape. The clamping block 22 can float up and down along the length of the guide rod 23. During the tape application process, since the guide rod 23 and the spring 24 are installed between the clamping block 22 and the base 21, it can be ensured that the force of the clamping block 22 to stick the tape to the buffer paper pad is uniform. Moreover, due to the presence of the spring 24, there will be no rigid contact between the clamping block 22 and the buffer paper pad. The spring 24 can effectively reduce the impact force of the clamping block 22 on the buffer paper pad, ensuring that the clamping block 22 will not damage the discharge port of the external buffer paper pad making machine during the tape application process.

[0055] refer to Figures 1 to 3 The ends of the second guide roller 7 and the limiting roller 8 are both mounted on the bearing plate 1. The second guide roller 7 is located on the side of the pressing block 22, and the limiting roller 8 is located diagonally above the second guide roller 7. Figure 1 The second guide roller 7 is located to the right of the clamping block 22. Figure 1 The middle limiting roller 8 is located to the upper left of the second guide roller 7. The bottom of the limiting roller 8 is not lower than the top of the pressing block 22. In this embodiment, both the second guide roller 7 and the limiting roller 8 are rotatably connected to the bearing plate 1, that is, the second guide roller 7 and the limiting roller 8 can rotate on the bearing plate 1. In other embodiments, the ends of the second guide roller 7 and the limiting roller 8 can also be fixed on the bearing plate 1. The second guide roller 7 can guide the tape to be smoothly conveyed to the pressing block 22. Since the limiting roller 8 is located diagonally above the second guide roller 7 and the bottom of the limiting roller 8 is not lower than the pressing block 22, the limiting roller 8 can prevent the tape on the pressing block 22 from lifting up and prevent the tape from sticking to the buffer paper pad when it is not needed.

[0056] To prevent the tape from sticking to the limiting roller 8, the limiting roller 8 can be designed to be non-stick. The material of the limiting roller 8 can be a material with low friction, such as POM or polytetrafluoroethylene. Alternatively, a knurled or grooved structure can be formed on the surface of the limiting roller 8 to reduce the contact area between the adhesive surface of the tape and the surface of the limiting roller 8.

[0057] refer to Figure 1 and Figure 2 The cutter 5 is located on the side of the clamping block 22. Figure 1 The cutting blade 5 is located to the left of the clamping block 22, which is positioned between the cutting blade 5 and the second guide roller 7. The second driving component 6 can drive the cutting blade 5 to move up and down to pierce or cut the tape. The second driving component 6 can be mounted on the fixed plate 100 via a connecting plate. In this embodiment, the second driving component 6 is an electric push rod, and the cutting blade 5 is mounted on the drive rod of the electric push rod. The electric push rod can enable the cutting blade 5 to pierce the tape at a faster speed, thereby ensuring that the tape does not wrap the cushioning paper pad more tightly during the piercing process. If the tape is not pierced quickly, the tape will pull the cushioning paper pad on the cushioning paper pad roll in the opposite direction of the cushioning paper pad's conveying direction, causing the cushioning paper pad on the cushioning paper pad roll to wrap more tightly. If the tape is not quickly pierced by the cutter 5, the buffer paper pad will drag the tape forward, causing the adhesive on the tape to be scraped by the cutter 5, leaving adhesive residue on the cutter 5. This affects the sharpness of the cutter 5, and in severe cases, it may prevent the cutter 5 from piercing or cutting the tape. In other embodiments, the second drive component 6 may also be a cylinder or a linear motor as needed. The second drive component 6 may also adopt a structure of "rotary motor + lead screw + nut". The rotary motor drives the lead screw to rotate, and the nut is screwed onto the lead screw. The cutter 5 can be fixed on the nut. The second drive component 6 may also adopt a structure of "rotary motor + gear + rack". The rotary motor drives the gear to rotate, and the gear meshes with the rack. The cutter 5 can be fixed on the rack.

[0058] refer to Figure 2 In this embodiment, the top of the cutter 5 is formed with inclined triangular blades 51, which can make the cutter 5 quickly puncture the tape with less force.

[0059] refer to Figure 1 The end of the winding roller 3 is mounted on the bearing plate 1. The winding roller 3 can only rotate in one direction on the bearing plate 1, specifically in direction A. This ensures that the tape wrapped around the winding roller 3 remains in place during the upward movement of the pressing block 22. Figure 5 (As shown) It will not fall off and will not affect the normal forward conveying of the tape with the cushioning paper pad.

[0060] refer to Figure 4 The winding roller 3 includes a roller body 31, a one-way bearing 32, and a shaft 33. The end of the shaft 33 is fixed to the bearing plate 1. The inner ring of the one-way bearing 32 is fitted onto the shaft 33. The roller body 31 is cylindrical and fits onto the outer ring of the one-way bearing 32. Under the action of the one-way bearing 32, the roller body 31 can only rotate in one direction, that is, the roller body 31 can only guide the conveyor belt to be conveyed forward with the cushioning paper pad, and the conveyor belt cannot be conveyed in the opposite direction. Figure 1The middle roller 31 can only rotate in direction A, which ensures that the tape wrapped around the roller 31 during the upward movement of the pressing block 22 ( Figure 5 As shown, the tape will not fall off and will not affect the normal forward conveying of the tape with the cushioning paper pad. In addition, the surface of the roller 31 can be formed with knurling. The knurling on the roller 31 can increase the friction between the tape and the surface of the roller 31, further ensuring that the tape wrapped around the roller 31 will not fall off during the upward movement of the pressing block 22 and will not affect the normal forward conveying of the tape with the cushioning paper pad.

[0061] refer to Figure 3 The ends of the base 21, the winding roller 3, the second guide roller 7, and the limiting roller 8 are all mounted on a connecting piece 210. That is, the base 21, the winding roller 3, the second guide roller 7, and the limiting roller 8 are sandwiched between the connecting piece 210 and the bearing plate 1. The winding roller 3, the second guide roller 7, and the limiting roller 8 can rotate between the connecting piece 210 and the bearing plate 1. The connecting piece 210 can improve the overall stability of the tape pressing component 2 and the winding roller 3, the second guide roller 7, and the limiting roller 8 on the bearing plate 1.

[0062] Under the driving action of the first driving component, the support plate 1 can move up and down, and the support plate 1 drives the tape pressing component 2 to move up and down, so that the tape on the pressing block 22 can be pasted onto the cushioning paper pad; specifically, refer to Figures 1 to 3 Two parallel guide rails 101 are mounted on the fixed plate 100, and a slider 102 is mounted on each guide rail 101. The slider 102 can slide up and down along the guide rail 101. The support plate 1 is fixed on the two sliders 102, that is, the support plate 1 can move up and down on the fixed plate 100 along the two guide rails 101; Reference Figure 3 The first driving component includes a motor 41, a connecting rod 42, and a driving roller 43. The motor 41 is mounted on a fixed plate 100, which has a through hole. The rotating shaft 411 of the motor 41 passes through the through hole. The upper end of the connecting rod 42 is fixed to the rotating shaft 411 of the motor 41, and the end of the driving roller 43 is fixed to the lower end of the connecting rod 42. The axis of the driving roller 43 is parallel to the axis of the rotating shaft 411 of the motor 41. A transverse groove 11 is formed on the bearing plate 1, and the driving roller 43 is accommodated in the transverse groove 11. Figure 1As shown, when the shaft 411 of the motor 41 rotates, the end of the connecting rod 42 connected to the driving roller 43 moves in a circular motion around the shaft 411 of the motor 41. The connecting rod 42 drives the driving roller 43 to move in a circular motion around the shaft 411 of the motor 41. Since the driving roller 43 is housed in the transverse groove 11 on the bearing plate 1, the driving roller 43 can drive the bearing plate 1 to move up and down. That is, when the shaft 411 of the motor 41 rotates one revolution, the bearing plate 1 can move upward to the highest point and return to the initial position. The bearing plate 1 drives the tape pressing component 2 to move upward synchronously to the highest point. The tape is then returned to its initial position. When the pressing block 22 of the tape pressing component 2 moves upward to the highest point, the tape is adhered to the buffer paper pad. The first driving component, consisting of the motor 41, connecting rod 42, and driving roller 43, cooperates with the transverse groove 11 on the support plate 1, which allows the support plate 1 to move smoothly up and down. Moreover, the circular motion of the rotating shaft 411 of the motor 41 can be converted into the linear motion of the pressing block 22. In this way, there are no additional driving components such as cylinders or linear motors in the longitudinal space, providing installation space for the support rod 201 that carries the tape roll to be installed below the support plate 1.

[0063] refer to Figures 1 to 3 The mounting bracket 200 is fixed on the fixing plate 100. A rotatable support rod 201 is mounted on the mounting bracket 200. The support rod 201 is located below the winding roller 3 and is used to mount the tape roll.

[0064] refer to Figure 1 and Figure 3 The support plate 1 is also equipped with a rotatable first guide roller 12. The first guide roller 12 is located below the winding roller 3 and above the support rod 201. The first guide roller 12 can guide the tape roll installed on the support rod 201 to smoothly and tautly pass around the winding roller 3.

[0065] refer to Figure 1 A photoelectric sensor 13 can also be installed on the support plate 1. The photoelectric sensor 13 is located on the side of the first guide roller 12. The photoelectric sensor 13 can detect whether there is tape around the first guide roller 12. When there is tape between the first guide roller 12 and the winding roller 3, the photoelectric sensor 13 is triggered and generates a switch signal. The photoelectric sensor 13 can send the switch signal to a controller (microcontroller or single-chip microcomputer). Only when the controller receives the switch signal sent by the photoelectric sensor 13 can the motor 41 and the second drive component 6 work. If the photoelectric sensor 13 is not triggered, it means that there is no tape between the first guide roller 12 and the winding roller 3. At this time, the motor 41 and the second drive component 6 cannot work. The operator needs to feed new tape to ensure that there is tape around the first guide roller 12, the winding roller 3, and the second guide roller 7 and then on the pressing block 22.

[0066] Figure 5 schematically shown Figure 1 The image shows the usage status of the tape application mechanism.

[0067] The adhesive tape applicator of this invention is used in conjunction with a cushioning paper rewinding device. (See reference...) Figure 5 The clamping block 22 is installed below the discharge port 401 of the cushioning paper pad machine. The bottom of the discharge port 401 of the cushioning paper pad machine has an opening 403. The clamping block 22 is located directly below the opening 403. The tape roll 300 is installed on the support rod 201. The free end of the tape 301 of the tape roll 300 passes through the first guide roller 12, the winding roller 3, and the second guide roller 7 in sequence and is located on the clamping block 22. The tape 301 passes between the limiting roller 8 and the second guide roller 7, and the adhesive surface of the tape 301 is attached to the winding roller 3. The distance between the clamping block 22 and the inner top of the discharge port 401 is set as follows. When the clamping block 22 moves upward to its highest point, the distance between the upper surface of the clamping block 22 (the surface used to support the tape) and the inner top of the discharge port 401 is less than or equal to 15mm. Therefore, when the clamping block 22 adheres the tape to the buffer paper pad in the discharge port 401, the top of the buffer paper pad presses against the inner top of the discharge port 401, allowing the clamping block 22 to firmly adhere the tape to the buffer paper pad. After the buffer paper pad winding device has finished winding a roll of buffer paper pad, under the drive of the motor 41, the bearing plate 1 drives the clamping block 22. The pressing block 22 moves upward, pushing the tape 301 upward, thus adhering the tape 301 to the tail of the cushioning paper pad roll. After the cushioning paper pad winding device restarts for a certain period, the tape 301 is adhered and wrapped around the outer periphery of the cushioning paper pad roll. Then, the second drive component 6 drives the cutter 5 to move upward, piercing or cutting the tape 301. The cushioning paper pad winding device then winds up and tightly adheres the remaining unadhered tape on the cushioning paper pad roll, completing the tape wrapping and adhering of one roll of cushioning paper pads. In this invention's tape-adhering mechanism, during the tape-adhering process, the pressing block 22... 2. The tape can be smoothly adhered to the cushioning paper pad, and the force of the pressing block 22 in adhering the tape to the cushioning paper pad is uniform, thereby ensuring the adhesion effect of the tape and preventing the cushioning paper pad from unraveling after winding. In addition, since the winding roller 3 rotates in one direction, it can be ensured that the tape wound on the winding roller 3 will not fall off during the upward movement of the pressing block 22 and will not affect the normal forward conveying of the tape with the cushioning paper pad, thereby ensuring the winding efficiency of the cushioning paper pad. The limiting roller 8 can prevent the tape on the pressing block 22 from sticking up and prevent the tape from sticking to the cushioning paper pad when it is not needed.

[0068] Figures 6 to 8 The diagram schematically illustrates the structure of a buffer paper pad winding device according to one embodiment of the present invention.

[0069] refer to Figures 6 to 8A cushioning paper pad winding device includes a winding mechanism 10 and an adhesive tape applicator. The cushioning paper pad winding device is used in conjunction with a cushioning paper pad machine 400 that produces cushioning paper pads. An adhesive tape clamping component 2 is installed below the discharge port 401 of the cushioning paper pad machine 400. A material trough 402 is installed between the winding mechanism 10 and the discharge port 401 of the cushioning paper pad machine 400. An opening 403 is formed at the bottom of the discharge port 401 of the cushioning paper pad machine 400. The clamping block 22 of the adhesive tape clamping component 2 is located directly below the opening 403. The winding mechanism 10 can wind and rewind the continuous cushioning paper pads produced by the cushioning paper pad machine 400.

[0070] refer to Figures 6 to 8 The winding mechanism 10 includes a turntable 20, a winding rod 30, a pusher plate 40, a third drive component 50, a fourth drive component 60, a crank-connecting rod mechanism 70, a guide rod 80, and a mounting plate 90. The ends of the winding rod 30 are fixed to the turntable 20. There are two winding rods 30, located at opposite ends of the turntable 20 in the diametrical direction. The third drive component 50 is mounted on the mounting plate 90 and is driven by a transmission mechanism consisting of two synchronous pulleys 501 and a synchronous belt (not shown). The rotating turntable 20 rotates. The third drive component 50 can be a torque motor. The pusher plate 40 is annular, with the inner diameter of the pusher plate 40 slightly larger than the outer diameter of the turntable 20. The pusher plate 40 is circumferentially arranged around the turntable 20. The guide rod 80 passes through the mounting plate 90 via a bushing. One end of the guide rod 80 is fixed to the pusher plate 40, and the guide rod 80 can slide along its length on the mounting plate 90. The fourth drive component 60 is a motor, which is mounted on the mounting plate 90. The crank-connecting rod mechanism 70... The input end is mounted on the shaft of the fourth drive component 60, and the output end of the crank-connecting rod mechanism 70 is fixed on the pusher plate 40. The fourth drive component 60 can drive the pusher plate 40 to move along the length direction of the winding rod 30 through the crank-connecting rod mechanism 70. The mounting plate 90 can support the third drive component 50, the fourth drive component 60, the turntable 20, and the pusher plate 40. The pusher plate 40 can move smoothly back and forth along the length direction of the winding rod 30 through the guide rod 80. The shaft of the fourth drive component 60 (i.e., the motor) rotates one revolution. The crank-connecting rod mechanism 70 can drive the pusher plate 40 to push out the buffer paper roll on the winding rod 30 and retract the pusher plate 40 to its original position. In addition, the tightness of the buffer paper roll during the winding process can be adjusted by adjusting the speed of the torque motor and the output speed of the buffer paper roll machine 400. For example, if the torque motor rotates fast and the output speed of the buffer paper roll machine 400 is slow, the winding of the buffer paper roll will be tighter. If the torque motor rotates slowly and the output speed of the buffer paper roll machine 400 is fast, the winding of the buffer paper roll will be looser.

[0071] refer to Figures 6 to 8There are three guide rods 80, which are arranged in a triangular pattern on the pusher plate 40. Under the driving action of the fourth drive component 60, the pusher plate 40 can move smoothly back and forth along the two winding rods 30. In other embodiments, the number of guide rods 80 can be adjusted as needed.

[0072] refer to Figure 6 The feed trough 402 of the cushioning paper pad machine 400 can be configured such that the free end of the feed trough 402 ( Figure 6 The left end of the material trough 402 floats up and down with the discharge port 401 as the center. A tension spring can be installed between the material trough 402 and the discharge port 401. When the two winding rods 30 are winding the buffer paper pad, the free end of the material trough 402 can be attached to the outer periphery of the buffer paper pad roll.

[0073] Figure 9 schematically shown Figure 6 The shown image shows the operating status of the cushioning paper rewinding device.

[0074] refer to Figure 9 The tape roll 300 is mounted on the support rod 201. The free end of the tape 301 of the tape roll 300 passes through the first guide roller 12, the winding roller 3, and the second guide roller 7 in sequence and is located on the pressing block 22. The tape 301 passes between the limiting roller 8 and the second guide roller 7, and the adhesive surface of the tape 301 is attached to the winding roller 3.

[0075] refer to Figure 9 The continuous cushioning paper pads produced by the cushioning paper pad machine 400 are conveyed to the winding mechanism 10 through the discharge port 401 and the feed trough 402. When the third drive component 50 drives the turntable 20 to rotate, the two rotating winding rods 30 on the turntable 20 wind up the cushioning paper pads. After the cushioning paper pad of a set length is delivered from the discharge port 401 of the cushioning paper pad machine 400, the cutter component at the discharge port 401 of the cushioning paper pad machine 400 cuts the cushioning paper pad. When the winding mechanism 10 is about to finish winding up the cushioning paper pad of the set length, the motor 41 ( Figure 1 Under the driving action of the third driving component 50 (as shown), the bearing plate 1 drives the pressing block 22 to move upward, and the pressing block 22 pushes the tape 301 upward, thereby sticking the tape 301 to the tail of the cushioning paper pad roll. As the third driving component 50 starts again for a certain period of time, the tape 301 can be pasted and wrapped around the outer periphery of the cushioning paper pad roll. Then the second driving component 6 drives the cutter 5 to move upward, and the cutter 5 punctures or cuts the tape 301. The winding mechanism 10 winds up and tightly wraps the remaining unpainted tape on the cushioning paper pad roll. The tape wrapping and pasting of a roll of cushioning paper pad is completed. Then the fourth driving component 60 ( Figure 8Under the driving action (as shown), the pusher plate 40 moves along the length direction of the winding rod 30, and the pusher plate 40 can push the wound buffer paper pad roll on the winding rod 30 out of the winding rod 30. Then the pusher plate 40 retracts along the length direction of the winding rod 30 to reset, preparing for the next push. In the buffer paper pad winding device of this utility model, during the process of pasting tape, the clamping block 22 can smoothly paste the tape onto the buffer paper pad, and can ensure that the force of the clamping block 22 to paste the tape onto the buffer paper pad is uniform, thereby ensuring the pasting effect of the tape and preventing the buffer paper pad from unraveling after winding. In addition, since the winding roller 3 rotates in one direction, it can ensure that the tape wound on the winding roller 3 will not fall off during the upward movement of the clamping block 22 and will not affect the normal forward conveying of the tape with the buffer paper pad, thereby ensuring the winding efficiency of the buffer paper pad. The limiting roller 8 can prevent the tape on the clamping block 22 from sticking up and prevent the tape from sticking to the buffer paper pad when it is not needed.

[0076] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
