Description

Technical Field

[0001] This utility model relates to the field of tape peeling technology, specifically a tape peeling mechanism. Background Technology

[0002] According to patent number CN207792281U, a tape peeling and feeding device is disclosed, comprising: a feeding mechanism, a peeling mechanism corresponding to the feeding mechanism; a receiving mechanism disposed on one side of the peeling mechanism in a conveying direction; a receiving drive mechanism, the output end of which is drivenly connected to a receiving shaft; and a traction component disposed between the feeding mechanism and the peeling mechanism. The traction component includes a conveying shaft, a traction shaft, and a traction drive mechanism, the output end of which is drivenly connected to the traction shaft. The traction shaft moves closer to or away from the conveying shaft via the traction drive mechanism. Unlike existing technologies, this invention uses only the receiving drive mechanism as the power drive for tape receiving, and the traction component as the traction power for tape, effectively providing tape with the protective film after peeling. This avoids asynchronous feeding and receiving, is convenient to use, and has high peeling efficiency. The peeling mechanism in the aforementioned patent is overly complex, prone to tape entanglement, and difficult to repair when part of the mechanism malfunctions, leading to reduced efficiency. Furthermore, pulling the tape requires manual labor, increasing workload.

[0003] Chinese Utility Model Publication No. CN216887554U discloses a tape peeling mechanism, which relates to the field of tape peeling. It includes a side plate, a first fixed shaft fixedly connected to the front of the side plate, an intermediate gear on the surface of the axle, a driven gear meshing with the top of the intermediate gear, a second fixed shaft inside the driven gear, the back of the second fixed shaft fixedly connected to the front of the side plate, a circular ring fixedly connected to the side of the driven gear, a tape roll on the surface of the circular ring, and the second fixed shaft on the surface inside the circular ring.

[0004] The device moves the packaging box via a conveyor belt, which compresses the tape to adhere it. Then, the tape is cut and peeled off by contact with a cutter. However, the device relies solely on the natural compression between the conveyor belt and the tape to achieve adhesion, without actively compacting the tape at the adhesion point to the item. This results in poor adhesion. Without a secondary compaction process after adhesion, the tape is prone to lifting or detaching from the item's surface under external forces during subsequent handling and transmission, affecting the packaging quality. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a tape peeling mechanism.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a tape peeling mechanism, comprising a side plate, a tape roll, an intermediate gear, and a driven gear. A transmission belt for conveying items is provided on the front of the side plate, and a rack is fixedly connected to the back of the transmission belt. The top of the rack and the bottom of the intermediate gear are meshed together. A baffle is arrayed on the top of the transmission belt, and a cutter is fixedly connected to the top of the baffle. A fixing tube is provided on the side wall of the side plate, and a lifting seat is slidably installed inside the fixing tube. Rollers are installed on both sides of the lifting seat, and pressing pads for pressing the tape are installed on the outside of the rollers, flexibly pressing the tape. An installation groove is provided inside the lifting seat, and the lower part of the installation groove extends through the bottom of the lifting seat. A rebound device is installed inside the installation groove, and rollers are provided below the rebound device to cooperate with rollers to convey the pressing pads. During operation, the rebound device applies downward pressing force to rollers.

[0007] Furthermore, the rebound device includes an elastic element and a sliding plate, the sliding plate sliding up and down in the mounting groove; the upper part of the elastic element is disposed at the top of the mounting groove, and the lower part of the elastic element is disposed at the top of the sliding plate, generating a downward thrust on the sliding plate.

[0008] Furthermore, the elastic element is a spring.

[0009] Furthermore, the lower part of the lifting seat is provided with an extension tube, and the inside of the extension tube is provided with a through groove running vertically through the body. The mounting groove of the lifting seat is completely overlapped with the through groove, which is used to increase the extension amount of the sliding plate moving downward.

[0010] Furthermore, the center point of roller two is higher than the top surface of the item, and the lowest point of the lower edge of roller two is lower than the top surface of the item.

[0011] Preferably, the side wall of the lifting seat is provided with several threaded holes, one of which is threaded with a bolt.

[0012] Preferably, the side wall of the fixing tube is provided with a through hole, and the through hole and the bolt are arranged in a through-hole configuration.

[0013] Preferably, the pressure pad has a certain degree of shrinkage.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a tape peeling mechanism, which has the following beneficial effects: The tape peeling mechanism has a connecting seat that fixes roller one and roller two to form a stable inverted triangle structure. When an item passes over it, it pushes roller two, triggering the rebound device to exert a reverse force, causing roller two to apply pressure evenly to the tape through the pressing pad, firmly pressing the tape onto the item. This improves the tape adhesion effect to a certain extent and ensures the packaging quality. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the prior art, a tape peeling mechanism includes a side plate 1, a tape roll 2, an intermediate gear 3, and a driven gear 4. The front of the side plate 1 is provided with a transmission belt 5 for conveying items. A rack 6 is fixedly connected to the back of the transmission belt 5. The top of the rack 6 and the bottom of the intermediate gear 3 are meshed. A baffle 7 is arranged on the top of the transmission belt 5. A cutter 8 is fixedly connected to the top of the baffle 7. When the transmission belt 5 is started, the baffle 7, the cutter 8, and the packaging box or other items placed on the transmission belt 5 are moved. At the same time, the meshing intermediate gear 3 is rotated, which in turn drives the driven gear 4 to rotate, thus adhering the tape to the packaging box or other items. The cutter 8 cuts the tape into segments. This is the prior art and will not be elaborated on here.

[0019] Please see Figure 1-2This utility model discloses a tape peeling mechanism. A fixing tube 9 is provided on the side wall of the side plate 1. A groove is provided inside the fixing tube 9. The lower part of the groove passes through the lower part of the fixing tube 9 to form a slot. The upper part of the lifting seat 10 extends into the groove from the slot and slides with the fixing tube 9. When the lifting seat 10 slides up and down, the height of the lifting seat 10 is adjusted so that the position of the lifting seat 10 can be flexibly adjusted according to the size of the packaging box or other items. A through hole is provided on the side wall of the fixing tube 9, and the through hole and the bolt 17 are connected through each other. Several threaded holes are provided on the side wall of the lifting seat 10. The bolt 17 is installed in one of the threaded holes. The bolt 17 is passed through the through hole of the fixing tube 9 and then screwed into the corresponding threaded hole of the lifting seat 10 to fix the lifting seat 10 at that height.

[0020] Rollers 11 are installed on both sides of the lifting seat 10. Each roller 11 includes a connecting rod fixedly installed on the side wall of the lifting seat 10. One end of the connecting rod and the roller 11 are rotatably connected together through a rotating shaft, bearing or bushing. A pressing pad 18 for pressing the tape is installed on the external drive of the roller 11. The drive belt 5 drives the item to move. After contacting the tape, the tape and the pressing pad 18 collide. The pressing pad 18 flexibly presses the tape, and the collision and friction drive the pressing pad 18 to move, thereby driving the roller 11 to rotate.

[0021] The lifting seat 10 has an internal mounting groove 12, and the lower part of the mounting groove 12 penetrates the bottom of the lifting seat 10 to form a slot. A rebound device is installed from the slot into the mounting groove 12. The lower part of the rebound device is provided with a roller 13. The roller 13 includes a connecting rod fixedly mounted on the side wall of the rebound device. One end of the connecting rod and the roller 13 are rotatably mounted together through a rotating shaft, bearing or bushing, etc., and cooperate with the roller 11 to convey the pressing pad 18, forming an inverted triangular shape. The side wall of the item carrying the tape impacts one side of the roller 13. On the pressing pad 18, the roller 13 moves upward under the impact force, and the compression rebound device moves into the mounting groove 12. At this time, the pressing pad 18 on the lower left side of the roller 13 moves from the side wall of the item to the upper surface of the item, pressing the tape onto the upper surface. When the item is removed from the roller 13, the rebound device pushes the roller 13 downward, and at the same time, the pressing pad 18 on the lower right side of the roller 13 exerts pressure on the left side of the item, adhering the tape to the seat of the item, thereby improving the adhesion effect of the tape.

[0022] The pressing pad 18 has a certain degree of contractility. When the roller 2 13 is pushed upward by an object, the pressing pad 18 contracts. The inner wall of the pressing pad 18 is always in contact with the roller 11 and roller 2 13 and will not slip off the roller 11 and roller 2 13.

[0023] Please see Figure 3The rebound device includes an elastic element and a sliding plate 14. The sliding plate 14 slides up and down in the mounting groove 12, driving the roller 13 to move up and down. The upper part of the elastic element is set at the top of the mounting groove 12, and the lower part of the elastic element is set at the top of the sliding plate 14, generating a downward pushing force on the sliding plate 14, causing the roller 13 to generate a downward pressing force on the pressing pad 18, thereby pressing the tape onto the item.

[0024] The elastic element is spring 15. Spring 15 is a common elastic component, which is inexpensive and readily available, so spring 15 is preferred.

[0025] Please see Figure 4 The lower part of the lifting seat 10 is provided with an extension tube 16. The inside of the extension tube 16 is provided with a through groove that runs vertically through the body. The through groove completely overlaps with the mounting groove 12 of the lifting seat 10. The sliding plate 14 slides from the mounting groove 12 into the through groove of the extension tube 16, which increases the downward extension of the sliding plate 14 and prevents the sliding plate 14 from detaching from the mounting groove 12.

[0026] The center point of roller 13 is higher than the top surface of the item, and the lowest point of the lower edge of roller 13 is lower than the top surface of the item. This allows roller 13 to move upward when the top of the item hits a position below the center of roller 13, thereby causing the sliding plate 14 to slide upward within the mounting groove 12.

[0027] In summary, when using this tape peeling mechanism, the equipment is started, the transmission belt 5 rotates, and the item to be tapered is placed on top of the transmission belt 5. The item moves with the transmission belt 5, first contacting the tape released from the tape roll 2, and then causing the tape to collide with the pressing pad 18. The pressing pad 18 exerts pressure on the right side of the item, pressing the tape onto the right side of the item. At the same time, the impact force pushes the roller 13 upward, and the roller 13 drives the sliding plate 14 to compress the spring 15, moving it into the mounting slot of the lifting seat 10. 12 retracts inward. At this time, the pressing pad 18 on the left side of roller 2 13 transitions from the side wall of the item to the upper surface, flexibly pressing the tape to make the tape initially adhere. The item continues to move with the transmission belt 5. After disengaging from roller 2 13, the spring 15 extends and resets, pushing the sliding plate 14 and roller 2 13 downward. The pressing pad 18 on the right side of roller 2 13 exerts pressure on the left side of the item, further compacting the tape and completing the adhesion. The item continues to move to the cutter 8, and the cutter 8 cuts the tape, ending the single adhesion process.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
