Description

Technical Field

[0001] This utility model relates to the field of label paper rewinders, and in particular to a paper clamping structure for a label paper rewinder. Background Technology

[0002] Label paper rewinders are auxiliary devices widely used in logistics, warehousing, and retail. They are mainly used to automatically rewind labels or remaining backing paper after the label printer has finished printing, in order to keep the working environment clean and improve operational efficiency.

[0003] Before rewinding, the label paper needs to be fixed. In the existing technology, the end of the label paper is usually wrapped around the rewinding shaft manually before the rewinder is started to rewind. This method is not only inefficient, but the end of the label paper is also prone to loosening and shifting during the rewinding process, resulting in loose, shifted, or even jammed labels, which affects subsequent rewinding processes and requires frequent manual adjustments. Summary of the Invention

[0004] The purpose of this invention is to provide a paper clamping structure for a label paper rewinder to solve the above-mentioned problems.

[0005] According to one aspect of the present invention, a paper clamping structure for a label paper rewinder is provided, comprising: a rewinder body, a rewind shaft, and a paper clamping part, wherein the rewind shaft is detachably connected to the output end of the rewinder body, the rewind shaft has a cavity, the cavity contains a magnet, the rewind shaft has at least one groove for accommodating the paper clamping part, the paper clamping part is magnetically engaged with the magnet, and after the paper clamping part is magnetically engaged with the magnet, the label paper is clamped between the paper clamping part and the groove.

[0006] In some embodiments, the output end of the rewinder body is provided with a fixing ring whose inner diameter is the same as the outer diameter of the rewind shaft. A screw hole is provided on one side of the fixing ring, and a fixing bolt is screwed into the screw hole. The fixing bolt is in contact with the rewind shaft.

[0007] In some embodiments, the cavity is a cylindrical structure, and the magnet is a cylindrical structure adapted to the cavity.

[0008] In some embodiments, the groove has an arc-shaped structure.

[0009] In some embodiments, the paper clamping part includes a straight rod that cooperates with the groove body, one end of the straight rod extending vertically to a stop bar, the straight rod being used to press the label paper, and the stop bar being used to block the label paper roll.

[0010] In some embodiments, the paper clamping portion is made of a ferromagnetic material.

[0011] In some embodiments, the groove is arranged along the axial direction of the rewind shaft.

[0012] In some embodiments, four grooves are evenly distributed on the rewind shaft.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] The detachable rewind shaft of this application can be replaced with a specific rewind shaft according to the needs of the label paper, realizing quick loading and unloading and improving winding efficiency; through the magnetic cooperation between the paper clamping part and the magnet, the end of the label paper can be fixed in the groove. During the winding process, the label paper will not become loose, shifted or even accumulate and jam, which improves winding efficiency and is simple to operate, saving manpower and material resources. Attached Figure Description

[0015] Figure 1 This is a three-dimensional structural diagram of the present invention;

[0016] Figure 2 This is a schematic diagram of the cross-sectional structure of the rewind shaft of this utility model. Detailed Implementation

[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] refer to Figures 1 to 2 This application provides a paper clamping structure for a label paper rewinder, including: a rewinder body 1, a rewind shaft 2, and a paper clamping part. The rewind shaft 2 is detachably connected to the output end of the rewinder body 1. The rewind shaft 2 has a cavity 3, and a magnet 4 is placed inside the cavity 3. The rewind shaft 2 has at least one groove 5 for accommodating the paper clamping part. The paper clamping part is magnetically engaged with the magnet 4. After the paper clamping part is magnetically engaged with the magnet 4, the label paper is clamped between the paper clamping part and the groove 5.

[0019] In some embodiments, the output end of the rewinder body 1 is provided with a fixing ring 6 whose inner diameter is the same as the outer diameter of the rewind shaft 2. A screw hole 7 is provided on one side of the fixing ring 6, and a fixing bolt is screwed into the screw hole 7. The fixing bolt contacts the rewind shaft 2, and the rewind shaft 2 is loaded and unloaded by tightening or loosening the fixing bolt.

[0020] In some embodiments, the cavity 3 is a cylindrical structure, and the magnet 4 is a cylindrical structure adapted to the cavity 3.

[0021] In some implementations, the groove 5 has an arc-shaped structure to prevent the label paper from being scratched by the edge of the groove 5.

[0022] In some embodiments, the paper clamping part includes a straight rod 8 that cooperates with the groove body 5. One end of the straight rod 8 extends vertically and is provided with a stop bar 9. The straight rod 8 is used to press the label paper, and the stop bar 9 is used to block the label paper roll.

[0023] In some embodiments, the paper clamping part is made of ferromagnetic material and magnetically engages with magnet 4.

[0024] In some embodiments, the groove 5 is arranged along the axial direction of the rewind shaft 2.

[0025] In some embodiments, four grooves 5 are evenly distributed on the rewind shaft 2, which can be used to magnetically clamp the label paper and enhance its firmness.

[0026] The specific winding principle of this application is as follows: one end of the label paper is magnetically clamped into the groove 5 by the paper clamping part, and the output end of the rewinder body 1 rotates to drive the rewinding shaft 2 to rotate. The rotation of the rewinding shaft 2 also retracts the label paper. In some embodiments, the output end of the rewinder body 1 can also be flipped to prevent the label paper roll from winding.

[0027] The detachable rewind shaft 2 of this application can be replaced with a specific rewind shaft 2 according to the needs of the label paper, so as to achieve quick loading and unloading and improve the winding efficiency. Through the magnetic cooperation between the paper clamping part and the magnet 4, the end of the label paper can be fixed in the groove 5. During the winding process, the label paper will not become loose, shifted or even accumulate and jam, which improves the winding efficiency and is simple to operate, saving manpower and material resources.
