Description

Technical Field

[0001] The present application relates to the technical field of printers, and in particular to a device for preventing the adhesive surface of a bottomless paper tape from sticking to a channel. Background Art

[0002] In existing printing technologies, especially when it comes to linerless paper rolls using self-adhesive materials, there are often some operational challenges. Due to their sticky properties, when self-adhesive labels pass through the paper path during printing, their unused back side tends to adhere to the path surface, which may cause the paper to stick, wrinkle or block in the subsequent printing process, thus affecting the printing quality and efficiency.

[0003] Moreover, traditional paper feeding systems are usually designed for continuous sliding contact, which exacerbates the problem of adhesive adhesion when handling sticky materials. Since the adhesive layer of the adhesive is prone to leave residues when in contact with the channel, these residues will accumulate over time and increase the friction of the paper feeding channel, further causing the paper to not feed smoothly. Utility Model Content

[0004] To this end, the present application provides a device for preventing the adhesive surface of a linerless paper tape from sticking to a paper passage, so as to solve the problem in the prior art that linerless paper easily sticks to a paper passage.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A device for preventing the adhesive surface of a bottomless paper from sticking to a channel, comprising an upper channel bracket and a lower channel bracket arranged below the upper channel bracket, wherein the lower channel bracket comprises a horizontal plate parallel to the upper channel bracket and a vertical plate perpendicular to the horizontal plate, wherein the vertical plate is fixed to the bottom of the horizontal plate, and a paper feeding channel for bottomless paper to pass through is formed between the horizontal plate and the upper channel bracket;

[0007] A rubber roller is rotatably connected to the transverse plate, and the axis of the rubber roller is parallel to the transverse plate. A transmission mechanism for driving the rubber roller to rotate is arranged on the longitudinal plate, and the rubber roller partially protrudes beyond the upper surface of the transverse plate, and the bottom surface of the upper channel bracket is in contact with the peripheral wall of the rubber roller; a plurality of rollers are rotatably connected to the bottom of the transverse plate, and a circle of protruding teeth is arranged on the peripheral wall of each roller, the roller is located on one side of the rubber roller, and the axis of the roller is parallel to the axis of the rubber roller; a through hole is opened on the transverse plate directly above each roller, and each roller can have at least one protruding tooth passing through the corresponding through hole at the same time and protruding beyond the upper surface of the transverse plate.

[0008] Optionally, a plurality of groups of roller frames for fixing rollers are installed at the bottom of the transverse plate, each group of roller frames includes two clamping plates, and each clamping plate is provided with a clamping groove for the roller shaft to pass through.

[0009] Further optionally, the lower end of the slot is open and the opening width is smaller than the diameter of the roller shaft.

[0010] Optionally, the rollers are distributed in a matrix, and the opening positions of the through holes correspond to the rollers.

[0011] Optionally, the upper surface of the horizontal plate is recessed downward to form a groove for the rubber roller to be placed in, and mounting plates are provided at both ends of the groove. The mounting plates are provided with mounting grooves for the rubber roller shaft to pass through, and the upper ends of the mounting grooves are open.

[0012] Further optionally, the opening side wall of the mounting groove is chamfered.

[0013] Optionally, the protrusions on all rollers can extend beyond the upper surface of the cross plate to the same height.

[0024] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0026] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this application are usually used to indicate the general relative position relationship for the purpose of intuitive understanding by referring to the drawings, and are not absolute limitations on the position relationship in the actual product.

[0027] A device to prevent the adhesive surface of the bottomless paper from sticking to the channel, referring to Figure 1 and Figure 2 , including an upper channel support 1 and a lower channel support arranged below the upper channel support 1, wherein the upper channel support 1 is a plate-shaped structure with a flat bottom surface. The lower channel support includes a horizontal plate 2 parallel to the upper channel support 1 and a vertical plate 3 perpendicular to the horizontal plate 2, the vertical plate 3 is fixed to one side of the bottom of the horizontal plate 2, and there is a certain gap between the horizontal plate 2 and the upper channel support 1 to form a paper feeding channel for the bottomless paper 4 to pass through, and the upper surface of the horizontal plate 2 is flat, thereby preventing the bottomless paper 4 from being scratched.

[0028] Reference Figure 1 and Figure 3One side of the upper surface of the horizontal plate 2 is recessed downward to form a semi-cylindrical groove 5, and a rubber roller 6 is placed horizontally inside the groove 5. After the rubber roller 6 is placed in the groove 5, a part of the rubber roller 6 still exceeds the upper surface of the horizontal plate 2, and the bottom surface of the upper channel bracket 1 is in contact with the peripheral wall of the rubber roller 6. The length of the groove 5 is greater than the length of the rubber roller 6. Mounting plates 7 are fixed at both ends of the groove 5, and the setting direction of the mounting plates 7 is perpendicular to the axial direction of the rubber roller 6. Each mounting plate 7 is provided with a mounting groove for the shaft rod of the rubber roller 6 to pass through, so that the rubber roller 6 can be rotatably connected in the groove 5. In order to facilitate the disassembly and assembly of the rubber roller 6, the upper end of the mounting groove is open. At the same time, in order to prevent the rubber roller 6 from loosening and moving out of the groove 5, the width of the mounting groove opening is set to be slightly smaller than the diameter of the shaft rod of the rubber roller 6. Furthermore, the side wall of the mounting groove opening is set to a chamfered structure, so that the installation of the rubber roller 6 is more convenient and quick.

[0029] Specifically, the axis of the rubber roller 6 is parallel to the upper surface of the horizontal plate 2 and perpendicular to the surface of the longitudinal plate 3. A transmission mechanism 8 for driving the rubber roller 6 to rotate is arranged on the outer side of the longitudinal plate 3, and a driving member (not shown in the figure) for providing power to the transmission mechanism 8, such as a motor, is fixed on the inner side.

[0030] Reference Figure 1 and Figure 4 , a plurality of freely rotatable rollers 9 are arranged at the bottom of the horizontal plate 2, and a circle of protruding teeth 10 is arranged on the peripheral wall of each roller 9. Specifically, a plurality of roller 9 frames for fixing the rollers 9 are installed at the bottom of the horizontal plate 2, and each group of roller 9 frames includes two parallel clamping plates 11, and the gap between the two clamping plates 11 is slightly larger than the axial length of the roller 9, so that there is a certain gap between the roller 9 and the two clamping plates 11, so that they can rotate freely. A clamping groove for the roller 9 shaft to pass through is provided on the clamping plate 11, and the lower end of the clamping groove is open and the opening width is smaller than the diameter of the roller 9 shaft, so as to prevent the roller 9 shaft from falling.

[0031] All rollers 9 are on the same side of the rubber roller 6, and the axis of the roller 9 is parallel to the axis of the rubber roller 6. A through hole 12 is opened on the horizontal plate 2 just above each roller 9, and each roller 9 can have at least one protruding tooth 10 passing through the corresponding through hole 12 and exceeding the upper surface of the horizontal plate 2 at the same time.

[0032] It should be noted that, in order to prevent the protruding teeth 10 from cutting the bottomless paper 4, the specifications and installation heights of all rollers 9 are consistent, so that the height of the protruding teeth 10 that exceeds the upper surface of the horizontal plate 2 is also consistent, so as to prevent the bottomless paper 4 lifted by the protruding teeth 10 from being uneven. In addition, in order to be able to separate the bottomless paper 4 from the horizontal plate 2 and the upper channel bracket 1, the height that the protruding teeth 10 can exceed the upper surface of the horizontal plate 2 should be less than the height difference between the top surface of the rubber roller 6 and the upper surface of the horizontal plate 2.

[0033] The rollers 9 are distributed in a matrix under the transverse plate 2 , and the opening positions of the through holes 12 correspond to the rollers 9 .

[0034] The implementation principle of the embodiment of the present application is as follows: during the implementation process, the bottomless paper 4 is mounted on the protruding teeth 10 of the roller 9. Under the support of the protruding teeth 10, the bottomless paper 4 is separated from the paper feeding channel (i.e., away from the cross plate 2 and the upper channel bracket 1). The bottomless paper passes between the rubber roller 6 and the upper channel bracket 1 and is clamped by the two. Therefore, when the transmission mechanism 8 drives the rubber roller 6 to rotate, the rotation of the rubber roller 6 can drive the bottomless paper 4 to move through friction to achieve paper feeding. At the same time, the movement of the bottomless paper 4 will drive the roller 9 to rotate. When the previous protruding teeth 10 leave the rubber surface of the bottomless paper 4, the next protruding teeth 10 will follow and hold the rubber surface of the bottomless paper 4. The purpose of preventing the rubber surface of the bottomless paper 4 from adhering to the protruding teeth 10 is achieved by rotation.

[0035] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
