[0031] The specific implementation process of the present invention is described below through multiple embodiments.

[0032] Example 1

[0033] See also Figures 1 to 5 This embodiment discloses a specific implementation of a release paper roller.

[0034] See also Figures 1 to 5 , a release paper roller includes a rotating shaft 1, an arc surface portion 2 and a sticker portion 3, the sticker portion 3 is detachably mounted on the arc surface portion 2, and the sticker portion 3 protrudes from the arc surface portion 2; the sticker portion 3 includes a sticker surface 31 and a first transition portion 32 and a second transition portion 33 arranged on both sides of the sticker surface 31, and at least one row of first air holes 311 is arranged on the surface of the sticker surface 31; a first air distribution component 4 and a second air distribution component 5 are arranged at both ends of the rotating shaft 1; in the process of the rotating shaft 1 driving the arc surface portion 2 and the sticker portion 3 to rotate one circle, the first air hole 311 is successively in a negative pressure state, a positive pressure state and a pressureless state.

[0035] Specifically, see Figure 4 The purpose of this embodiment is to attach the long strip of release paper to the predetermined position of the bag body 6, where a pressure-sensitive adhesive 61 is pre-adhered. Figure 4 The first air distribution assembly 4 and the second air distribution assembly 5 simultaneously distribute air to the sticker portion 3. Since the sticker surface 31 is long and narrow, with a length of up to 600 mm, the simultaneous air distribution of the first air distribution assembly 4 and the second air distribution assembly 5 can ensure a uniform and faster air distribution speed at the first air holes 311 at all locations, facilitating the timely absorption or outward blowing of the long strip of release paper.

[0036] The working process of the release paper roller is as follows: In the first step, the long strip of release paper is adsorbed on the sticker surface 31. Figure 5 As shown in A; In the second step, the long strip of release paper is rotated to Figure 5 At the aforementioned point B, during the process from point A to point B, the sticker surface 31 is in a negative pressure state; thirdly, during the process from point B to point C, the sticker surface 31 is in a positive pressure state, and the long strip of release paper is blown outward and pressed onto the surface of the pressure-sensitive adhesive 61; fourthly, during the process from point C to point A, the sticker surface 31 is in a non-pressure state; according to the cycle from the first step to the fourth step, the release paper roller completes the pressing and attaching of a long strip of release paper each time it rotates one circle.

[0037] See also Figures 1 to 5 , the first air distribution component 4 and the second air distribution component 5 have the same structure. The first air distribution component 4 is taken as an example for explanation below. The first air distribution component 4 includes an air distribution disk 41 and an air source disk 42. A negative pressure exhaust hole 421, a positive pressure blowing hole 422, an arc-shaped waist hole groove 423 and a hole-free area 424 are set on the air source disk 42. The positive pressure blowing hole 422 is adjacent to the arc-shaped waist hole groove 423, and the negative pressure exhaust hole 421 is connected to the arc-shaped waist hole groove 423; a mounting groove 411 is set on the air distribution disk 41, The mounting groove 411 is provided with a second air hole 412 and a third air hole 413; the sticker portion 3 is provided with a first horizontal hole 34 and a second horizontal hole 35, and the first horizontal hole 34 is connected to the first air hole 311; when the first horizontal hole 34 is aligned with the second air hole 412 and the second air hole 412 is aligned with the arc-shaped waist hole groove 423, the first air hole 311 is in a negative pressure state. During the rotation of the shaft 1, the arc surface portion 2, the sticker portion 3 and the gas distribution disk 41 rotate together, while the gas source disk 42 remains stationary. Figure 5In the process from point A to point B, the second air hole 412 is aligned with the arc-shaped waist hole groove 423, and the sticker surface 31 is in a negative pressure state; when the second air hole 412 is aligned with the positive pressure blowing hole 422, the first air hole 311 is in a positive pressure state. In the process from point B to point C, the second air hole 412 is aligned with the positive pressure blowing hole 422, and the sticker surface 31 is in a positive pressure state; when the second air hole 412 is aligned with the non-porous area 424, the first air hole 311 is in a non-pressure state. In the process from point C to point A, the second air hole 412 is aligned with the non-porous area 424, and the sticker surface 31 is in a non-pressure state. Figure 1 and Figure 2 The first transition portion 32 is detachably mounted on the sticker surface 31 , and the surface of the second transition portion 33 is an arc surface.

[0038] Through this embodiment, the long strip of release paper is adsorbed on the sticker surface 31. On the one hand, when the sticker surface 31 rotates one circle, the first air hole 311 is in a negative pressure state, a positive pressure state and a pressure-free state successively. In the negative pressure state, the long strip of release paper is adsorbed, and in the positive pressure state, air is blown and the long strip of release paper is pressed onto the area to be pasted. In the pressure-free state, it is ready to receive the next long strip of release paper, thereby achieving efficient absorption and pressing of the long strip of release paper; on the other hand, the first air distribution component 4 and the second air distribution component 5 respectively distribute air to the sticker surface 31 from both ends, so that the air pressure of the first air holes 311 at different parts of the sticker surface 31 tends to be consistent, which facilitates more efficient adsorption or blowing away of the long strip of release paper.
