[0002] A label paper roll, also known as a roll label or a disk label, is a material used by a label printer. Its characteristic is that it exists in the form of a roll and is suitable for the needs of a large number of continuous printing.

[0003] The packaging of label paper rolls is usually carried out by a heat shrink packaging machine. When using the heat shrink packaging machine, the product to be packaged needs to be placed on the conveyor belt of the heat shrink packaging machine to ensure that the products are neatly arranged. The equipment will automatically stretch the packaging film from the reel and cover it on the surface of the product for sealing and cutting. When the product passes through the heat shrinkage area, the heater will heat the packaging film covering the product to make it shrink and tightly wrap the product.

[0004] In the prior art, when using a heat shrink packaging machine for label paper rolls, it is usually necessary for workers to manually place the label paper rolls on the conveyor belt for conveying, which easily leads to different distances or mutual contact when each label paper roll is conveyed.

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 work shall fall within the protection scope of the present invention.

[0026] Embodiment 1

[0027] Please refer to Figures 1-6 , the present invention provides a technical solution: a label paper packaging device, including a heat shrink packaging machine 100, on which there is a material conveyor belt 101; two mounting seats 200 are symmetrically and fixedly installed on the top side of the material conveyor belt 101, a storage structure is installed on the two mounting seats 200, a U-shaped frame 300 is installed on the storage structure, a discharge structure is installed on the U-shaped frame 300, a lifting plate 400 is installed on the storage structure, and an adjusting structure is installed on the lifting plate 400.

[0028] Furthermore, the storage structure includes two adjusting slide bars 201, which are respectively slidably installed on the two mounting seats 200. The same bin 202 is fixedly installed on the side of the two adjusting slide bars 201 close to each other. The bottom side of the bin 202 is fixedly installed with a bottom plate 203. A discharge port 204 is opened on the bin 202. A plurality of label paper rolls 205 are movably installed in the bin 202, and the label paper rolls 205 are located on the top side of the bottom plate 203.

[0029] Further, the discharging structure includes a transmission shaft 301 rotatably installed on a U-shaped frame 300. The U-shaped frame 300 is fixedly installed on the bottom side of the bottom plate 203. Two driving rollers 302 are fixedly sleeved on the transmission shaft 301. Transmission belts 303 are installed on both of the two driving rollers 302. A plurality of driven rollers 304 are installed on both of the two transmission belts 303. The driven rollers 304 are rotatably installed on the U-shaped frame 300. A plurality of pushing rods 305 are fixedly installed on both of the two transmission belts 303. A plurality of sliding holes 306 are formed in the bottom plate 203. A plurality of communication holes 307 are formed in the material bin 202. The sliding holes 306 and the communication holes 307 on the same side are communicated with each other. The pushing rods 305 are movably installed in corresponding sliding holes 306. The pushing rods 305 on the same side correspond to the communication holes 307. A first bevel gear 308 is fixedly sleeved on the transmission shaft 301. A feeding motor 309 is fixedly installed on one side of the U-shaped frame 300. The output end of the feeding motor 309 penetrates through the U-shaped frame 300 and is fixedly installed with a second bevel gear 310. The second bevel gear 310 meshes with the first bevel gear 308. Before use, the label paper roll 205 can be stacked in the material bin 202. When using the heat shrink packaging machine 100 to package the label paper roll 205, the feeding motor 309 can be turned on to drive the pushing rods 305 to move in a circular motion by the transmission belts 303. Furthermore, the pushing rods 305 can contact the label paper roll 205 on the bottom plate 203 and push it to move. Finally, under the continuous pushing of the pushing rods 305, the label paper roll 205 can be pushed onto the material conveyor belt 101. During the process, the label paper roll 205 located above will fall back onto the bottom plate 203 again. Thus, under the action of the continuous circular motion of the pushing rods 305, the label paper roll 205 can be intermittently pushed onto the material conveyor belt 101. By adjusting the rotation speed of the feeding motor 309, the discharging speed can be adjusted, and further the discharging distance between the two label paper rolls 205 can be adjusted.

[0031] Further, a pressing screw 207 is threadedly installed in the inner wall of the mounting seat 200. One end of the pressing screw 207 is fixedly installed with a pressing block 208. The pressing block 208 contacts one side of the adjusting sliding rod 201. By rotating the pressing screw 207, the pressing block 208 can be driven to press on the adjusting sliding rod 201, so as to adjust and fix the position of the adjusting sliding rod 201.

[0032] Further, an adjustment screw hole 209 is formed in the inner wall of the mounting base 200. The pressing screw rod 207 is threadedly installed in the adjustment screw hole 209. The pressing block 208 is located in the adjustment screw hole 209. The adjustment screw hole 209 communicates with the guiding sliding hole 206. Rotating the pressing screw rod 207 can make it rotate and move in the adjustment screw hole 209 through the threaded fit with the adjustment screw hole 209.

[0033] Embodiment 2

[0034] As Figures 2-5 , in order to enable the size of the discharge port 204 to be adjusted and adapted according to the height of the stored label paper roll 205, an adjustment structure is arranged on the lifting plate 400. The adjustment structure includes a lifting lead screw 401. The lifting lead screw 401 is threadedly installed on the lifting plate 400. The lifting plate 400 is slidably installed on the inner wall of the storage bin 202. The lifting plate 400 is located in the discharge port 204. The lifting lead screw 401 is rotatably installed on the inner wall of the storage bin 202. One end of the lifting lead screw 401 penetrates through the storage bin 202 and is fixedly installed with a knob 402. Vertical sliding grooves 403 are formed in both inner walls of the storage bin 202. Vertical sliders 404 are slidably installed in the two vertical sliding grooves 403 respectively. The two vertical sliders 404 are fixedly installed on both sides of the lifting plate 400 respectively. A lifting screw hole 405 is formed in the inner wall of the lifting plate 400. The lifting lead screw 401 is threadedly installed in the lifting screw hole 405. By rotating the knob 402, the lifting lead screw 401 can be driven to rotate. The rotating lifting lead screw 401 can drive the lifting plate 400 to move vertically through the threaded fit with the lifting screw hole 405. The vertically moving lifting plate 400 can drive the vertical sliders 404 on both sides to slide in the corresponding vertical sliding grooves 403 respectively, thereby restricting the moving direction of the lifting plate 400. By adjusting the height of the lifting plate 400, the discharge port 204 can be blocked or opened. The remaining features are the same as those in Embodiment 1.

[0035] The working principle is as follows: Before use, the label paper roll 205 can be stacked in the bin 202. When using the heat shrink packaging machine 100 to package the label paper roll 205, the feeding motor 309 can be turned on. The output end of the feeding motor 309 can drive the second bevel gear 310 to rotate. The rotating second bevel gear 310 drives the transmission shaft 301 to rotate through meshing with the first bevel gear 308, so that the transmission shaft 301 drives the two driving rollers 302 to rotate simultaneously. Through the transmission cooperation among the driving roller 302, the transmission belt 303 and the transmission roller 304, when the driving roller 302 rotates, it can drive a plurality of transmission rollers 304 to rotate. At the same time, the transmission belt 303 will perform a circular motion, and the circular motion of the transmission belt 303 will drive the pushing rod 305 to perform a circular motion. As a result, the pushing rod 305 can move in the sliding hole 306 and the communication hole 307. By setting the sliding hole 306 and the communication hole 307, the offset of the pushing rod 305 can be avoided. The continuously moving pushing rod 305 will contact the label paper roll 205 on the bottom plate 203 and push it to move, so that the label paper roll 205 moves on the bottom plate 203 and is removed from the bin 202 through the discharge port 204. Finally, under the continuous pushing of the pushing rod 305, the label paper roll 205 can be pushed onto the material conveyor belt 101. During the process, the label paper roll 205 located above will fall back onto the bottom plate 203 again. Thus, under the action of the continuous circular motion of the pushing rod 305, the label paper roll 205 can be intermittently pushed onto the material conveyor belt 101. By adjusting the rotation speed of the feeding motor 309, the discharge speed can be adjusted, and then the discharge spacing between the two label paper rolls 205 can be adjusted. By rotating the pressing screws 207 on both sides, they can rotate and move in the adjusting screw holes 209 through the threaded cooperation with the adjusting screw holes 209. The moving pressing screws 207 will drive the pressing blocks 208 to disengage from the pressing of the adjusting slide rod 201. At this time, the position limit of the adjusting slide rod 201 can be released. Then, the adjusting slide rod 201 can be pushed or pulled to adjust the position of the bin 202 on the top side of the material conveyor belt 101. After adjustment, the pressing screws 207 can be rotated in the reverse direction to make the pressing blocks 208 press on the adjusting slide rod 201 again to prevent the position offset of the adjusting slide rod 201 and the bin 202. By rotating the knob 402, the lifting screw rod 401 can be driven to rotate. The rotating lifting screw rod 401 can drive the lifting plate 400 to move vertically through the threaded cooperation with the lifting screw hole 405. The vertically moving lifting plate 400 can drive the vertical sliders 404 on both sides to slide in the corresponding vertical sliding grooves 403 respectively, thereby restricting the moving direction of the lifting plate 400. By adjusting the height of the lifting plate 400, the discharge port 204 can be blocked or opened, so as to adjust according to the height of the label paper roll 205 stored in the bin 202.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
