[0001] This invention relates to the field of adhesive tape label processing, and in particular to an adhesive tape label folding and winding device. Background Technology

[0002] In the production process of adhesive tape labels, the tape is generally wound up using rollers. Before winding, the large tape roll is cut into multiple independent tape rolls. To ensure the user experience and appearance quality of the tape labels, the large tape roll needs to be folded before being split and wound up. The excess waste generated from folding and splitting is usually collected by a collection roller. However, since tape label waste is usually generated at the edge of the tape roll, the waste collected by the collection roller will be wrapped around both ends. The collection roller needs to be stopped and cleaned after each tape roll is processed, resulting in a high cleaning frequency. Summary of the Invention

[0003] In view of the problems in the above or existing technologies where adhesive label waste also has good adhesion, after being collected by the collection roller, the waste will be firmly wrapped on the collection roller under the action of tension, making it difficult to clean. At the same time, residual adhesive is also easy to stick to the collection roller, which is not easy to clean. Therefore, the present invention is proposed.

[0004] Therefore, the purpose of this invention is to provide a tape label folding and winding device.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Example 1, referring to Figure 1 , Figure 2 and Figure 7 This is the first embodiment of the present invention. This embodiment provides a tape label folding and winding device, including a frame 1 for fixing and supporting the device, a tape roll 2 set on the frame 1 for use as raw material for processing finished tape labels, a tape divider 5 set on the frame 1 for dividing the tape roll 2, a folding unit 3 set on the frame 1 for releasing the tape roll 2 and folding the released tape roll 2 to facilitate the tape divider 5 to cut the tape roll 2 through the fold, a finished product winding unit 4 set on the frame 1 for wrapping the divided tape roll 2 with a paper tube to wind it into finished tape labels and fold and grind the edges of the finished products, a tensioning unit 6 set on the frame 1 for maintaining tension when the tape roll 2 is released and working with the folding unit 3 to maintain the uniformity of the folding operation of the tape roll 2, and a folding waste material winding unit 7 set on the frame 1 for collecting the excess waste material generated by folding and dividing the tape. The tensioning unit 6 maintains sufficient tension on the tape roll 2, and the folding unit 3 folds the tape roll 2. Then, the folding waste material winding unit 7 quickly winds up and releases the waste material generated by the tape roll 2 during the folding process.

[0030] The tensioning unit 6 includes a tensioning roller 61 mounted on the frame 1 for contacting the tape roll 2 and for contacting the smooth surface of the released portion of the tape roll 2; sliding blocks 62 mounted at both ends of the tensioning roller 61; sliding grooves 63 mounted on the frame 1 for cooperating with the sliding blocks 62; and an electric push rod 64 mounted on the sliding groove 63 for driving the sliding blocks 62 to move the tensioning roller 61 up and down in the sliding groove 63, maintaining the tension force when the tape roll 2 is released, and ensuring uniformity of the folding operation of the folding unit 3 on the tape roll 2; and an electric push rod 64 mounted on the sliding groove 63 for driving the sliding blocks 62 to drive the tensioning roller 61 up and down in the sliding groove 63, maintaining the tension of the released portion of the tape roll 2. A tension sensor is installed on the tension roller 61 to detect the force exerted on the tension roller 61 by the tape roll 2 in real time, and provide data feedback to the electric push rod 64 to control the tension roller 61 to move up and down.

[0031] In summary, when the device is started, the folding unit 3 starts, driving the tape roll 2 to rotate and release while simultaneously folding the released portion of the tape roll 2. At this time, the tape divider 5 divides the tape roll 2 through the folds, separating the released tape roll 2 into multiple parts. Simultaneously, the finished product winding unit 4 starts, winding the divided tape roll 2 into finished tape labels. At the same time, the folding waste winding unit 7 starts, collecting the waste generated after the tape roll 2 is folded and divided. During this process, the tensioning unit 6 remains running, and the tension sensor monitors the force of the tape roll 2 on the tensioning roller 61 in real time, feeding back to the electric push rod 64. The electric push rod 64 drives the tensioning roller 61 to move up and down, keeping the tension of the tape roll 2 within a reasonable range, thus ensuring the continuous operation of the folding unit 3 and the folding waste winding unit 7.

[0032] Example 2, refer to Figures 1-7 This is the second embodiment of the present invention. Unlike the previous embodiment, it provides the specific structures of the folding unit 3 and the finished product winding unit 4 in the tape label folding and winding device. Compared to embodiment 1, the folding unit 3 further includes a motor 31 mounted on the frame 1 to generate power; a drive wheel 32 mounted on the drive end of the motor 31 to rotate in coordination with the motor 31; a folding assembly 33 mounted on the frame 1 to fold the released portion of the tape roll 2 while simultaneously releasing it; and a transmission belt 34 mounted on the drive wheel 32 to drive the folding assembly 33 to move using the power of the hull. The tape roll 2 is provided with a driven wheel 21 to cooperate with the drive belt 34. The drive belt 34 drives the driven wheel 21 to rotate through the drive wheel 32, thereby driving the tape roll 2 to be released in conjunction with the folding assembly 33.

[0033] The folding assembly 33 includes a convex roller 331 and a concave roller 332 mounted on the frame 1. The convex roller 331 and the concave roller 332 clamp the release portion of the tape roll 2, keeping the tape roll 2 in a flat state as it passes through the convex roller 331 and the concave roller 332. At the same time, the convex roller 2 is released as it rotates. The convex roller 331 has a gear 333 mounted on it, and the concave roller 332 has a gear 334 mounted on it and connected to the gear 333. The gear 333 and the gear 334 drive the convex roller 331 and the concave roller 332 to rotate in opposite directions, thereby clamping and releasing the tape roll 2. The gear 333 also has a driven wheel 335 mounted on the gear 333 to drive the gear 333 to rotate as it is driven by the transmission belt 34. The driven wheel 335 is driven by the transmission belt 34 to drive the gear 333 to rotate, thereby driving the folding assembly 33. The convex roller 331 is provided with an annular protrusion 3311 to cooperate with the finished product winding unit 4, and the concave roller 332 is provided with an annular groove 3321 to cooperate with the annular protrusion 3311. The annular protrusion 3311 and the annular groove 3321 cooperate to squeeze and fold the tape roll 2 that is clamped and released by the convex roller 331 and the concave roller 332, destroying the structure at the fold and forming a crease. This makes it easier for the tape separator 5 to separate the tape roll 2 through the crease, keeping the edge of the finished product winding uniform and preventing the generation of burrs and wrinkles.

[0034] The finished product winding unit 4 includes a motor 41 on the frame 1 for generating power, a winding roller 42 on the frame 1 driven by the motor 41 for rotating in coordination with the motor 41, and a paper tube 43 on the winding roller 42 for rotating in coordination with the winding roller 42 to wind up the tape roll 2 after separation. The take-up roller 42 is segmented and is equipped with an edge-folding grinding wheel 44, which is used to fold and grind the edges of the tape roll 2 wound on the paper tube 43 to further reduce burrs and stickiness.

[0035] The number of blades on the tape divider 5 is set in accordance with the number and spacing of the annular protrusions 3311. This setting ensures that the creases on the tape roll 2 correspond one-to-one with the blades on the tape divider 5. During the release of the tape roll 2, the creases pass through the blades and divide the tape roll 2 into multiple identical parts, achieving uniform cutting of the tape roll 2.

[0036] The rest of the structure is the same as in Example 1.

[0037] In summary, when the device is started, motor 31 starts, driving drive wheel 32 to rotate. Drive wheel 32 drives driven wheel 21 and driven wheel 335 to rotate via drive belt 34. Driven wheel 21 rotates and releases tape roll 2. The convex roller 331 and concave roller 332 cooperate to clamp the released portion of tape roll 2 and convey it outward. The portion of tape roll 2 that passes through convex roller 331 forms folded edges through the cooperation of annular protrusion 3311 and annular groove 3321. It is then divided into parts by tape divider 5. Motor 41 starts synchronously and drives paper tube 43 to rotate via take-up roller 42 to wind up the divided tape roll 2. At this time, folding grinding wheel 44 rotates synchronously with take-up roller 42 to fold and grind the two sides of the tape roll 2 wound by paper tube 43, further eliminating burrs and wrinkles.

[0038] Example 3, referring to Figures 1-10 This is the second embodiment of the present invention. Unlike the previous embodiment, it provides a specific structure for the waste material winding unit 7 in the tape label folding and winding device. Compared to embodiment 2, the waste material winding unit 7 further includes a motor 71 mounted on the frame 1 for generating power; a winding assembly 72 mounted on the drive end of the motor 71 for rotating in conjunction with the motor 71 to wind up the generated waste material; a toggle assembly 73 mounted on the frame 1 for cooperating with the winding assembly 72 to toggle the waste material left and right, ensuring the waste material is evenly wound around the position of the winding assembly 72, preventing excessive winding at a fixed position and thus requiring waste material cleaning; and a transmission belt 74 mounted on the winding assembly 72 for driving the toggle assembly 73 through the movement of the winding assembly 72.

[0039] The winding assembly 72 includes a connecting shaft 721 disposed on the drive end of the motor 71, which serves to connect and transmit power; a collecting roller 722 disposed on the connecting shaft 721, which is used to rotate in cooperation with the connecting shaft 721; and a contact element 723 disposed on the collecting roller 722, which is used to rotate in cooperation with the collecting roller 722 to wind up the waste material.

[0040] The contact element 723 includes a support block 7231 slidably disposed on the collection roller 722 for moving up and down on the collection roller 722; a contact wheel 7232 disposed on the support block 7231 for contacting the waste material of the tape roll 2 for direct contact with the waste material, thereby converting the lateral friction between the waste material and the contact wheel 7232 into rolling friction, which facilitates the removal of the entangled waste material from the contact wheel 7232; and an abutment rod 7233 disposed in the collection roller 722 for slidingly supporting the support block 7231, thereby supporting the support block 7231. The contact surface of the sliding connection between the abutment rod 7233 and the support block 7231 is set as an inclined surface. With this setting, when the abutment rod 7233 is pulled, the inclined surface generates a pulling force on the support block 7231 in the direction of the collecting roller 722, which drives the support block 7231 to slide into the collecting roller 722, so that the contact wheel 7232 disengages from the abutment of the wound waste, and the waste wound on the contact wheel 7232 can be quickly removed.

[0041] The actuating assembly 73 includes a connecting shaft 731 mounted on the transmission belt 74 for rotating in coordination with the transmission belt 74; a bidirectional lead screw 732 mounted on the connecting shaft 731 for rotating in coordination with the connecting shaft 731; movable blocks 733 mounted at both ends of the bidirectional lead screw 732 and threadedly connected to the bidirectional lead screw 732 for moving back and forth in coordination with the rotation of the bidirectional lead screw 732; a guide shaft 734 mounted on the movable blocks 733 for actuating the waste material in coordination with the back and forth movement of the movable blocks 733, and, in coordination with the rotation of the winding assembly 72, for evenly winding the waste material on the contact wheel 7232; and a slide rod 735 mounted on the frame 1 and slidably connected to the movable blocks 733 for limiting the sliding motion, and, in coordination with the rotation of the bidirectional lead screw 732, for allowing the movable blocks 733 to move back and forth only on the slide rod 735, thus actuating the waste material back and forth. The guide shaft 734 is inclined relative to the side of the waste material. This arrangement increases the contact area between the guide shaft 734 and the waste material, preventing the waste material from being subjected to force on one side edge, which could lead to breakage.

[0042] The rest of the structure is the same as in Example 2.

[0043] In summary, when the take-up roller 42 winds up the tape roll 2 after it has been split through the paper tube 43, the motor 71 starts synchronously. At this time, the collecting roller 722 rotates through the connecting shaft 721, and the support block 7231 rotates in coordination with the collecting roller 722. The waste material is wound up, and when it is wound, it abuts against the contact wheel 7232. At this time, under the action of the transmission belt 74, the bidirectional screw 732 rotates, and the guide shaft 734 is driven by the movable block 733 to move the waste material back and forth. Under the guidance of the guide shaft 734, the waste material is evenly wound on the contact wheel 7232. When it is necessary to clean the wound waste material, the collecting roller 722 is removed from the device. Then, the abutment rod 7233 is pulled, and the support block 7231 is moved towards the collecting roller 722 through the inclined surface. At this time, the contact wheel 7232 abuts against the waste material roll. Through the rolling friction between the contact wheel 7232 and the waste material roll, the waste material roll can be quickly removed from the actuating component 73. Then, the winding component 72 is installed back on the device.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
