[0036] It can be understood that with reference to Figures 1 to 5 , an embodiment of the first aspect of the present utility model provides a stripper, which includes a frame 100 and a conveying roller set 200. The frame 100 is used to connect to a printer, a conveying cavity 101 is formed inside the frame 100, and an inlet communicating with the conveying cavity 101 is provided at the upper end of the frame 100, such as Figure 4As shown in the figure, a baffle 130 is provided on the frame 100. The baffle 130 is arranged adjacent to the entrance. The separated label 310 falls on the side of the baffle 130 away from the entrance, and the substrate paper 320 enters the conveying cavity 101 from the entrance. A label sensor 330 is also installed at the upper end of the frame 100 to detect the separated label 310 through the label sensor 330. When the label 310 is taken away, the label sensor 330 sends a signal, and the printer prints the next label 310 and peels it off. When the label sensor 330 detects the label 310, the printing stops. The conveying roller group 200 is connected to the frame 100. The conveying roller group 200 includes a peeling rubber roller 210 and a peeling pressure roller 220. The peeling rubber roller 210 and the peeling pressure roller 220 are located at the upper part of the conveying cavity 101 and close to the entrance. The peeling pressure roller 220 is made of metal, such as stainless steel, aluminum alloy, etc. The outer wall of the peeling pressure roller 220 is provided with anti-slip patterns. It can be understood that the peeling rubber roller 210 is made of rubber or silica gel and has a certain elasticity. The peeling rubber roller 210 and the peeling pressure roller 220 cooperate to clamp the substrate paper 320. The metal peeling pressure roller 220 can press on the peeling rubber roller 210, causing the peeling rubber roller 210 to deform slightly, which is beneficial to clamping the substrate paper 320 and improving the friction force with the anti-slip patterns, which is beneficial to conveying the substrate paper 320.

[0037] When the stripper proposed by the present utility model operates, the conveying roller group 200 composed of the peeling rubber roller 210 and the peeling pressure roller 220 clamps the substrate paper 320. The peeling rubber roller 210 contacts and drives the substrate paper 320 to move. The peeling pressure roller 220 is made of metal and has anti-slip patterns on its outer wall. The friction force between the peeling pressure roller 220 and the substrate paper 320 is large, preventing the substrate paper 320 from slipping and running off, increasing the pulling force on the substrate paper 320, which is beneficial to peeling. A baffle 130 is provided on the frame 100 to block the peeled label 310 with the baffle 130, preventing the label 310 from being carried away by the substrate paper 320 and improving the reliability of use.

[0038] Refer to Figure 1 and Figure 2 In some embodiments of the first aspect of the present utility model, the frame 100 includes a fixing plate 110 and a cover plate 120. The lower end of the cover plate 120 is hinged to the fixing plate 110. Rotating the cover plate 120 can realize the opening and closing of the cover plate 120 relative to the fixing plate 110, that is, the conveying cavity 101 is formed between the fixing plate and the cover plate. Among them, the peeling rubber roller 210 is connected to the fixing plate 110, and the peeling pressure roller 220 is connected to the cover plate 120. When the cover plate 120 is in the closed state, it can be configured that the peeling pressure roller 220 contacts and slightly presses the peeling rubber roller 210, causing the peeling rubber roller 210 to deform slightly, which is beneficial to clamping the substrate paper 320 and increasing the pulling force on the substrate paper 320, which is beneficial to peeling.

[0039] It can be understood that in some embodiments of the first aspect of the present utility model, in order to drive the peeling pressure roller 220 to contact and slightly press the peeling rubber roller 210, a pressure roller bracket 140 is provided on the frame 100. Both ends of the peeling pressure roller 220 are rotatably connected to the pressure roller bracket 140. An elastic sheet 141 is provided at the upper end of the pressure roller bracket 140, and the upper end of the elastic sheet 141 is fixed to the cover plate 120. When the cover plate 120 is in the closed state, by using the elasticity of the elastic sheet 141, the peeling pressure roller 220 is pushed to press against the peeling rubber roller 210. The peeling pressure roller 220 can maintain contact and slightly press the peeling rubber roller 210. Even if there is an error in the relative position between the fixing plate 110 and the cover plate, it does not affect the use, reduces the assembly difficulty, and improves the reliability and stability during the use process.

[0040] In addition, other elastic members can also be used, such as torsion springs, elastic adhesives, etc., which can all meet the requirements of driving the peeling pressure roller 220 to contact and slightly press the peeling rubber roller 210.

[0041] Referring to Figure 2 and Figure 3 , in some embodiments of the first aspect of the present utility model, the cover plate 120 is provided with a hook plate 150.

The pin 111 can be the two ends of a smooth shaft. The hook plate 150 is provided with two hook portions 151. In the closed state, the hook portion 151 and the pin 111 cooperate to limit the cover plate 120. When it needs to be opened, by pressing or rotating the hook plate 150, the hook portion 151 is separated from the pin 111, so that the cover plate 120 can be opened.

[0042] It can be understood that in order to maintain the cooperation state between the hook portion 151 and the pin 111, as Figure 3 and Figure 5 shown, the cover plate 120 is provided with a hinge shaft 121. The hook plate 150 is hinged to the hinge shaft 121. Two torsion springs 122 are sleeved on the hinge shaft 121. One end of the torsion spring 122 is fixed to the cover plate 120, and the other end is connected to the hook portion 151. The torsion spring 122 is used to push the hook portion 151 to maintain an upward rotation trend, and the pin 111 is caught in the notch on the upper side of the hook portion 151, so that the hook portion 151 hooks the pin 111 to achieve the purpose of limiting the cover plate 120; when the cover plate 120 needs to be opened, by pressing the hook plate 150, the torsion spring 122 is compressed, so that the hook portion 151 is separated from the pin 111, and the cover plate 120 can be opened. For the convenience of operation, one end of the hook plate 150 extends outside the cover plate 120, and an opening cover decorative plate 152 is installed. The opening cover decorative plate 152 is close to the outer shape of the cover plate 120 and is convenient for operation.

[0043] It can be understood that there are two storage methods for the substrate paper 320 after peeling. The first is asFigure 4 As shown in the figure, a first outlet 103 is provided in the middle of the frame 100. The first outlet 103 is communicated with the conveying cavity 101. The first outlet 103 is located below the conveying roller group 200. The frame 100 is provided with a guide paper board 102. The guide paper board 102 is arranged obliquely in the conveying cavity 101. The upper end of the guide paper board 102 is adjacent to the conveying roller group 200. The lower end of the guide paper board 102 extends to the first outlet 103. After the bottom liner paper 320 passes through the conveying roller group 200, it is guided by the guide paper board 102 to the first outlet 103 for discharge and then collected.

[0044] The second type is as Figure 5 shown. The printer has a winding wheel 400 for winding the bottom liner paper 320. A second outlet 104 is provided at the lower part of the frame 100. The second outlet 104 is communicated with the conveying cavity 101. The frame 100 is connected with a lower guide roller 160. The lower guide roller 160 is located in the conveying cavity 101 and is distributed between the conveying roller group 200 and the second outlet 104. After the bottom liner paper 320 passes through the conveying roller group 200, it first bypasses the lower guide roller 160 and then is discharged from the second outlet 104. The winding wheel 400 winds the bottom liner paper 320. The lower guide roller 160 plays a role in tensioning and guiding to assist in winding.

[0045] The stripper can be adapted to two structures with and without winding, expanding the scope of use and having strong versatility.

[0046] Referring to Figure 2 , in some embodiments of the first aspect of the present invention, a guide roller 230 is connected to the upper end of the frame 100. A plurality of convex rings 231 are provided on the outer surface of the guide roller 230. The plurality of convex rings 231 are spaced apart along the axial direction of the guide roller 230. The convex rings 231 are made of metal and have a smooth outer surface. The guide roller 230 is arranged parallel to the conveying roller group 200 and is horizontally offset from the conveying roller group 200. As Figure 4 shown, the guide roller 230 is located above the conveying roller group 200. The stripping knife 500 is located above the guide roller 230. After the bottom liner paper 320 passes through the stripping knife 500, it enters the conveying cavity 101 from the inlet, first bypasses the guide roller 230, and then passes through the conveying roller group 200. The guide roller 230 can increase the turning angle of the bottom liner paper 320 on the stripping knife 500, which is beneficial to stripping. Moreover, the turning angle of the bottom liner paper 320 entering the conveying roller group 200 is also larger, which is beneficial to the conveying roller group 200 to clamp the bottom liner paper 320 and improve the pulling force. In addition, the convex rings 231 are made of metal and have a smooth outer surface, so that the contact area between the convex rings 231 and the bottom liner paper 320 is small, the frictional resistance is small, and the residual glue adhered to the bottom liner paper 320 on the guide roller 230 can be greatly reduced, maintaining the stability of use.

[0047] Referring to Figure 6, in some embodiments of the first aspect of the present utility model, the guide roller 230 includes a guide shaft 232 and a plurality of metal sleeves 233. The guide shaft 232 is connected to the frame 100. The plurality of metal sleeves 233 are sleeved on the guide shaft 232, and the metal sleeves 233 can rotate relative to the guide shaft 232. A convex ring 231 is provided on the outer wall of the metal sleeve 233, which facilitates assembly. Moreover, the metal sleeve 233 is easy to process and reduces costs.

[0048] It can be understood that the frame 100 is provided with a guide roller bracket 180. Both ends of the guide shaft 232 are installed on the guide roller bracket 180. The upper end of the elastic sheet 141 is located between the guide roller bracket 180 and the cover plate 120. The guide roller bracket 180 is fixed to the cover plate 120 by bolts. The elastic sheet 141 is also provided with through holes. The bolts pass through the through holes for fixing the guide roller bracket 180 and the through holes of the elastic sheet 141, and at the same time fix the guide roller bracket 180 and the elastic sheet 141.

[0049] Refer to Figure 6 , in some embodiments of the first aspect of the present utility model, the frame 100 is provided with a connecting seat 170. One end of the stripping rubber roller 210 is installed on the connecting seat 170. A bearing or a bushing can be provided in the connecting seat 170. The end of the stripping rubber roller 210 is supported by the bearing or the bushing. A transmission sleeve 171 is connected to the end of the stripping rubber roller 210. The transmission sleeve 171 is connected to a driving gear 172. The driving gear 172 is connected to a power member. For example, a motor and a gear are used as the power member. Thus, the stripping rubber roller 210 is driven to rotate through the driving gear 172 and the transmission sleeve 171, and the bottom liner paper 320 is driven by the stripping rubber roller 210. A plurality of circumferentially evenly distributed card slots are provided on the outer wall of the transmission sleeve 171. The driving gear 172 has a central hole for accommodating the transmission sleeve 171. Card ribs matching the card slots are provided inside the central hole.
