AI Technical Summary
When the label printing press peels off the residual paper, the label and the residual paper are prone to stick together, resulting in the label being unable to separate from the residual paper at one time, which in turn causes the label page to be damaged or the label edges are curled, affecting the quality of the label.
A paper strip separation device for label printing press is designed, including a body, a support plate, a guide wheel, a release paper guide roller and a residual paper guide mechanism. The residual paper guide mechanism uses air pressure to promote the separation of the residual paper from the label through the guide cylinder and the air intake device, so that the label is closely attached to the surface of the release paper to prevent the edges from being curled.
By setting up a residual paper guide mechanism, the air pressure acts on the label, effectively preventing the label from being curled or detached on the release paper, and improving the quality of the separation of the label paper.

[0002] A label printing machine, also known as a self-adhesive printing machine, is a device for printing labels and trademarks. The label printing and label equipment manufacturing have gradually formed a relatively independent system to adapt to the diversified development of the label application fields.
[0003] After the label is printed, it is necessary to peel the waste paper from the release paper through a separating device. During the peeling process, the waste paper and the label are prone to adhesion, resulting in the label being unable to be separated from the waste paper at one time, and then causing defects in the label page or warping of the label, etc., affecting the label quality. In view of this, we propose a label paper separating device for a label printing machine. Content of the Utility Model

Detailed Embodiment
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1-6 , a technical solution provided by the present invention:
[0024] A label paper separation device for a label printing machine, including a machine body 1. On one side of the machine body 1, two support plates 2 are fixedly connected. A guide wheel 3 and a release paper guide roller 4 are rotatably connected between the two support plates 2. A waste paper guiding mechanism 5 is arranged between the two support plates 2. During use, the guide wheel 3 exports the printed label paper, and the waste paper is separated from the release paper through the waste paper guiding mechanism 5.
[0025] Specifically, the waste paper guiding mechanism 5 in this embodiment includes a hollow guiding cylinder 51. The guiding cylinder 51 is rotatably connected to the two support plates 2 through a connecting member. When the waste paper passes through the guiding cylinder 51, it can drive the guiding cylinder 51 to rotate through friction, making the movement of the waste paper smoother. A plurality of air outlet holes 511 are formed on the surface of the guiding cylinder 51. One end of the guiding cylinder 51 is connected with an air inlet device. Through the air inlet device, gas can be introduced into the guiding cylinder 51. The gas is blown out through the plurality of air outlet holes 511 on the surface of the guiding cylinder 51, contacts the surface of the label, promotes the separation of the waste paper from the label through air pressure, and makes the label closely adhere to the surface of the release paper to prevent the label from warping.
[0026] Please refer to Figures 3-5 , the connecting member is a rotating sleeve 52. The outer circumference of the rotating sleeve 52 is rotatably connected to the inner wall of the support plate 2 through a bearing (not shown in the figure). The inner circumference of the rotating sleeve 52 is threadedly connected to the outer circumference of the guiding cylinder 51. Through the threaded transmission between the guiding cylinder 51 and the rotating sleeve 52, the position of the guiding cylinder 51 can be adjusted, so that the air outlet holes 511 on the surface of the guiding cylinder 51 can be aligned with the labels on the surface of the release paper. One end of the guiding cylinder 51 is fixedly connected with a turning handle 55, which is convenient for rotating the guiding cylinder 51. Both ends of the rotating sleeve 52 are fixedly connected with end plates 521. The outer diameter of the end plates 521 is greater than the outer diameter of the rotating sleeve 52. The opposite surfaces of the two end plates 521 are respectively in contact with both sides of the support plate 2, so that the rotating sleeve 52 cannot perform axial movement relative to the support plate 2. When the guiding cylinder 51 rotates, the rotating sleeve 52 is fixed to prevent it from rotating, and a screw drive can be generated between the guiding cylinder 51 and the rotating sleeve 52.
[0027] In this embodiment, the air intake device includes a fan 54 which is fixedly installed on the machine body 1. The output end of the fan 54 is communicated with a connecting pipe 53. One end of the connecting pipe 53 away from the fan 54 penetrates through the guiding cylinder 51 and extends into the guiding cylinder 51 to ventilate the guiding cylinder 51. A fixing bracket 57 is fixedly connected to the surface of the connecting pipe 53. The fixing bracket 57 is fixedly installed on the support plate 2. The fixing bracket 57 is used to fix one end of the connecting pipe 53 so that it will not rotate with the rotation of the guiding cylinder 51, avoiding pipeline twisting and winding. The connecting pipe 53 and the guiding cylinder 51 are hermetically connected through a sealing ring 56. The sealing ring 56 is made of silica gel material. The outer circumference of the sealing ring 56 is fixedly connected to the inner wall of the guiding cylinder 51, and the inner circumference of the sealing ring 56 is attached to the surface of the connecting pipe 53.
[0028] When the label paper separating device for the label printing machine of the present utility model is in use, first, the position of the air outlet holes 511 is adjusted according to the size of the label paper adopted. The specific method is as follows: press one side of the end plate 521 tightly, and then turn the turning handle 55, so that the guiding cylinder 51 rotates relative to the rotating sleeve 52. While the guiding cylinder 51 rotates, it axially moves relative to the rotating sleeve 52, so that the air outlet holes 511 can be aligned with the labels on the surface of the release paper, and the subsequent air pressure can directly act on the labels.
[0029] During the label printing process, the printed label paper will pass through the separation of the release paper guide roller 4 and the guiding cylinder 51, so that the waste paper is separated from the release paper. During the separation, the fan 54 is started. The fan 54 inputs gas into the guiding cylinder 51 through the connecting pipe 53. The gas blows out from a plurality of air outlet holes 511 on the surface of the guiding cylinder 51 and contacts the surface of the label. Through the air pressure, the separation of the waste paper and the label is promoted, and the label is tightly attached to the surface of the release paper to prevent the label from curling.
