[0002] During the production process of tape labels, the tape is generally wound by rollers, and the large tape roll is cut before winding, so that the tape after winding can be divided into multiple independent tape rolls. In order to ensure the user experience and appearance quality of the tape label during winding, the large tape roll needs to be folded and then wound up in strips. The excess waste generated by folding and dividing the tape is usually wound up by collecting rollers.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1, with reference to Figure 1 、 Figure 2 and Figure 7 , which is the first embodiment of the present invention, provides a tape label folding and winding device, including a frame 1 for fixing and supporting the device, a tape roll 2 arranged on the frame 1, which is used as a processing raw material for finished tape labels, a tape splitter 5 arranged on the frame 1, which is used to split the tape roll 2, and also includes a folding unit 3 arranged on the frame 1, which is used to drive the tape roll 2 to release and fold the released tape roll 2 to facilitate the tape splitter 5 to cut the tape roll 2 through the folding mark, a finished product winding unit 4 arranged on the frame 1, which is used to put a paper tube on the tape roll 2 after the tape is split and wind it up to process it into finished tape labels, and fold and grind the edges of the finished products, a tensioning unit 6 arranged on the frame 1, which is used to keep the tension when the tape roll 2 is released, and cooperate with the folding unit 3 to maintain the uniformity of the folding operation of the tape roll 2, and a folding waste winding unit 7 arranged on the frame 1, which is used to collect excess waste generated by folding and splitting. The tensioning unit 6 is used to maintain sufficient tension on the tape roll 2, and the folding unit 3 is used to fold the tape roll 2. The folding waste material rewinding unit 7 is then used to quickly rewind and release the waste material generated by the folding of the tape roll 2.

[0030] The tensioning unit 6 includes a tensioning roller 61 provided on the frame 1 for abutting the tape roll 2 and abutting the smooth surface of the released portion of the tape roll 2, sliding blocks 62 provided at both ends of the tensioning roller 61, and a sliding groove 63 provided on the frame 1 for cooperating with the sliding block 62. The sliding block 62 and the sliding groove 63 cooperate to move the tensioning roller 61 up and down in the sliding groove 63, thereby maintaining the tensioning force when the tape roll 2 is released, so that the folding operation of the folding unit 3 on the tape roll 2 remains uniform, and an electric push rod 64 provided on the sliding groove 63 for driving the sliding block 62, thereby driving the tensioning roller 61 to move up and down in the sliding groove 63 through the sliding block 62 to maintain the tension of the released portion of the tape roll 2. The tension roller 61 is provided with a tension sensor for detecting the force exerted by the tape roll 2 on the tension roller 61 in real time and providing data feedback to the electric push rod 64, thereby controlling the tension roller 61 to move up and down.

[0031] In summary, when the device is started, the folding unit 3 is started, driving the tape roll 2 to rotate and release, and folding the released part of the tape roll 2. At this time, the tape divider 5 divides the tape roll 2 through the creases, and divides the released tape roll 2 into multiple parts. At this time, the finished product winding unit 4 is started synchronously, and the tape roll 2 after division is wound into a finished tape label. At the same time, the folding waste winding unit 7 is started, and the waste generated after the tape roll 2 is folded and divided is collected by the folding waste winding unit 7. During this process, the tensioning unit 6 remains in the started state, and the tension sensor monitors the force of the tape roll 2 on the tensioning roller 61 in real time, and feeds back to the electric push rod 64. The electric push rod 64 drives the tensioning roller 61 to move up and down, so that the tension of the tape roll 2 is kept within a reasonable range to ensure the continuous operation of the corresponding operations of the folding unit 3 and the folding waste winding unit 7.

[0032] Example 2, reference Figure 1-Figure 7 This is the second embodiment of the present invention, which differs from the previous embodiment in that: it provides the specific structure of the folding unit 3 and the finished product winding unit 4 in the tape label folding and winding device. Compared with the first embodiment, the folding unit 3 further includes a motor 31 disposed on the frame 1 for generating power, a driving wheel 32 disposed on the driving end of the motor 31 for rotating in conjunction with the motor 31, a folding assembly 33 disposed on the frame 1 for driving the tape roll 2 to release and fold the released portion of the tape roll 2, and a transmission belt 34 disposed on the driving wheel 32 for driving the folding assembly 33 to move using the hull power. The tape roll 2 is provided with a driven wheel 21 to cooperate with the drive of the transmission belt 34. The transmission belt 34 drives the driven wheel 21 to rotate through the drive wheel 32, thereby driving the tape roll 2 to cooperate with the folding component 33 for release.

[0033] The folding assembly 33 includes a convex roller 331 provided on the frame 1 and a concave roller 332 provided on the frame 1. The convex roller 331 cooperates with the concave roller 332 to clamp the released part of the tape roll 2, keeping the tape roll 2 in a flat state when passing through the convex roller 331 and the concave roller 332, and at the same time cooperates with the rotation of the tape roll 2 to drive the release of the tape roll 2, a gear 1 333 provided on the convex roller 331, and a gear 2 334 provided on the concave roller 332 and connected to the gear 1 333. The gear 1 333 cooperates with the gear 2 334 to drive the convex roller 331 and the concave roller 332 to rotate in opposite directions, driving the tape roll 2 to clamp and release, and a driven wheel 2 335 provided on the gear 1 333 for cooperating with the drive belt 1 34 to drive the gear 1 333 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 correspondingly provided with an annular groove 3321 for cooperating with the annular protrusion 3311. The annular protrusion 3311 and the annular groove 3321 cooperate to squeeze and fold the tape roll 2 clamped and released by the convex roller 331 and the concave roller 332, thereby destroying the structure at the folded edge and forming a crease, so that the tape divider 5 can divide the tape roll 2 through the crease, keep the edge of the finished product winding uniform, and prevent the formation of burrs and wrinkles.

[0034] The finished product winding unit 4 includes a second motor 41 on the frame 1 for generating power, a winding roller 42 provided on the frame 1 and driven by the second motor 41 for rotating in conjunction with the second motor 41, and a paper tube 43 provided on the winding roller 42 for rotating in conjunction with the winding roller 42 to rewind the tape roll 2 after separation. The winding roller 42 is arranged in sections, and a folding grinding wheel 44 is provided on the winding roller 42 for folding and grinding the edge of the tape roll 2 wound on the paper tube 43 to further reduce burrs and sticking.

[0035] Among them, the number of blades on the tape divider 5 is set in correspondence with the number and spacing of the annular protrusions 3311. Through such a setting, the folds on the tape roll 2 correspond one-to-one to the blades on the tape divider 5. During the release process of the tape roll 2, the folds pass through the blades, dividing the tape roll 2 into multiple identical parts, thereby achieving uniform cutting of the tape roll 2.

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

[0037] In summary, when the device is started, the motor 31 starts, driving the driving wheel 32 to rotate, and the driving wheel 32 drives the driven wheel 21 and the driven wheel 2 335 to rotate through the transmission belt 1 34. At this time, the driven wheel 21 rotates to release the tape roll 2, and the convex roller 331 and the concave roller 332 cooperate to clamp the released part of the tape roll 2 and transport it outward. At this time, the part of the tape roll 2 passing through the convex roller 331 is formed by the cooperation of the annular protrusion 3311 and the annular groove 3321, and is divided into parts by the tape divider 5. The motor 2 41 starts synchronously and drives the paper roll 43 to rotate through the winding roller 42 to rewind the tape roll 2 after the tape is divided. At this time, the folding grinding wheel 44 cooperates with the winding roller 42 to rotate synchronously, and folds and grinds the edges of both sides of the tape roll 2 wound on the paper roll 43 to further eliminate burrs and wrinkles.

[0038] Example 3, reference Figures 1-10 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: a specific structure of the folding waste material winding unit 7 in the tape label folding and winding device is provided. Compared with Example 2, the folding waste material winding unit 7 further includes a motor 3 71 provided on the frame 1 for generating power, a winding assembly 72 provided on the driving end of the motor 3 71 for rotating in conjunction with the motor 3 71 to wind up the generated waste material, a shifting assembly 73 provided on the frame 1 for cooperating with the winding assembly 72 for shifting the waste material left and right so that the waste material is evenly wound at the position of the winding assembly 72, thereby preventing the waste material from being wound too much at a fixed position and requiring the waste material to be cleaned, and a transmission belt 2 74 provided on the winding assembly 72 for driving the shifting assembly 73 through the movement of the winding assembly 72.

[0039] Among them, the winding assembly 72 includes a connecting shaft 721 arranged on the driving end of the motor 3 71, which plays the role of connection and transmission, a collecting roller 722 arranged on the connecting shaft 721, which is used to cooperate with the connecting shaft 721 to rotate, and a contact piece 723 arranged on the collecting roller 722, which is used to cooperate with the collecting roller 722 to rotate and wind up the waste.

[0040] The contact member 723 includes a support block 7231 slidably disposed on the collecting roller 722 for moving up and down on the collecting roller 722; a contact wheel 7232 disposed on the support block 7231 for contacting the waste material on the tape roll 2, for directly contacting the waste material and converting the lateral friction between the waste material and the contact wheel 7232 into rolling friction, thereby facilitating the removal of the wound waste material from the contact wheel 7232; and an abutment rod 7233 disposed in the collecting roller 722 for slidably 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. Through such a setting, when the abutment rod 7233 is pulled, the inclined surface generates a pulling force toward the collecting roller 722 on the support block 7231, driving the support block 7231 to slide toward the collecting roller 722, so that the contact wheel 7232 is separated from the abutment against the wound waste, so that the waste wound on the contact wheel 7232 can be quickly removed.

[0041] The second end of the two-way screw rod 732 is connected to the two-way screw rod 732 by a screw thread, and is used to move back and forth through the rotation of the two-way screw rod 732; the guide shaft 734 provided on the movable block 733 is used to cooperate with the back and forth movement of the movable block 733 to shift the waste material, so that the waste material can be evenly wound around the contact wheel 7232 in cooperation with the rotation of the winding assembly 72; and the sliding rod 735 provided on the frame 1 and slidably connected to the movable block 733 plays the role of limited sliding, and cooperates with the rotation of the two-way screw rod 732 so that the movable block 733 can only move back and forth on the sliding rod 735 to shift the waste material back and forth. The guide shaft 734 is tilted relative to the side of the waste. This arrangement increases the contact area between the guide shaft 734 and the waste, preventing the waste from being subjected to stress on one side of the edge and causing breakage.

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

[0043] In summary, when the winding roller 42 rewinds the tape roll 2 after separation through the paper tube 43, the motor three 71 is started synchronously, and the collecting roller 722 rotates through the connecting shaft 1 721. At this time, the support block 7231 cooperates with the collecting roller 722 to rotate. The waste is rolled up and abuts against the contact wheel 7232 when it is wound. At this time, under the action of the transmission belt 2 74, the bidirectional screw rod 732 rotates, and the guide shaft 734 is driven to toggle the waste back and forth through the movable block 733. At this time, under the guidance of the toggle of the guide shaft 734, the waste is evenly wound around the contact wheel 7232. When the wound waste needs to be cleaned, the collecting roller 722 is removed from the device. At this time, the abutment rod 7233 is pulled, and the support block 7231 is driven to move toward the collecting roller 722 through the inclined surface. At this time, the contact wheel 7232 abuts against the waste roll. At this time, the waste roll can be quickly taken out from the toggle assembly 73 through the rolling friction between the contact wheel 7232 and the waste roll, and the winding assembly 72 is then installed 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 the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
