Technical Field
[0001] This utility model relates to the field of corrugated cardboard box production technology, specifically to an adjusting roller for a glue coating thickness die head. Background Technology
[0002] Corrugated cardboard boxes are one of the most widely used packaging products. During the production of corrugated cardboard boxes, the seams are usually glued to increase the structural strength of the boxes. Therefore, the application of glue determines the stability of the bonded corrugated cardboard boxes.
[0003] In existing technologies, a rotating coating roller is typically used to apply adhesive from a storage tank to a grooved storage tank on the surface of the roller. The rotating roller then applies the adhesive to the corrugated paper. The amount of adhesive applied to the corrugated paper is determined by the amount of adhesive in the storage tank. However, since the grooved storage tank on the surface of the roller is of a fixed size, the amount of adhesive applied cannot be adjusted for corrugated paper of different thicknesses. If too much adhesive is applied, the corrugated paper may absorb too much moisture from the adhesive and become soft, while too little adhesive will affect the bonding strength. Utility Model Content
[0004] The purpose of this invention is to provide an adjusting roller for a glue coating thickness die head, to solve the problems mentioned in the background art. In the prior art, the glue coating roller is usually rotated to apply glue from the glue storage tank to the grooved glue storage groove on the surface of the glue storage roller. Then, the rotating glue coating roller applies the glue to the corrugated paper. The amount of glue applied to the corrugated paper is determined by the amount of glue in the glue storage groove. However, since the grooved glue storage groove on the surface of the glue storage roller is of a fixed size, the amount of glue applied by the glue coating roller cannot be adjusted for corrugated paper of different thicknesses. If too much glue is applied, the corrugated paper is prone to absorbing too much water from the glue and becoming soft. If too little glue is applied, it will affect the bonding strength.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjusting roller for a coating thickness die head, comprising a frame, a coating section, and a pressing section:

A motor is located on the side of the frame, and the output end of the motor is connected to the glue application roller. The slider and the adjusting shaft are connected by a transmission. The adjusting shaft slides to drive the slider to slide within the glue storage grooves, thereby adjusting the glue storage amount. The pressing section is located inside the frame and has a slide frame that is slidably mounted inside the frame and a pressing roller that is rotatably mounted inside the slide frame. The pressing roller is located directly above the glue application roller and is pressed with corrugated cardboard to abut against the glue application roller.
[0007] By adopting the above technical solution, the sliding displacement of the adjusting shaft inside the glue coating roller can be controlled, thereby enabling the adjusting shaft to drive the slider to slide inside the glue storage tank, thus changing the depth of the glue storage tank and consequently changing the amount of glue stored in the glue storage tank.
[0008] Preferably, the surface of the coating roller is provided with twelve glue storage grooves, the twelve glue storage grooves are centrally rotationally symmetrical about the rotation axis of the coating roller, and each of the twelve glue storage grooves has a slider slidably disposed therein.
[0009] By adopting the above technical solution, the amount of glue stored in the glue storage tank can be changed by sliding the slider inside the glue storage tank.
[0010] Preferably, the adhesive application section also has a groove formed inside the adjustment shaft and a guide rod disposed at one end of the slider, the guide rod being embedded in the groove and slidably connected thereto.
[0011] By adopting the above technical solution, the slider can be driven to slide within the glue storage tank by adjusting the lateral sliding displacement of the shaft within the glue coating roller.
[0012] Preferably, the coating section also has a limiting frame disposed on the side of the frame and a limiting block slidably disposed inside the limiting frame. One end of the adjusting shaft passes through the limiting frame and is rotatably connected to it. The limiting block is fixed inside the limiting frame by bolts. The bottom semi-circular groove of the limiting block is engaged with the adjusting shaft.
[0013] By adopting the above technical solution, the position of the adjusting shaft can be fixed by the limit block.
[0014] Preferably, the adhesive coating part also has several limiting grooves formed at one end of the adjusting shaft, and the several limiting grooves are annular grooves surrounding the adjusting shaft that engage with the limiting block.
[0015] By adopting the above technical solution, the position of the adjusting shaft inside the coating roller can be controlled by engaging the limiting block with different limiting grooves.
[0016] Preferably, the pressing part also has a slide bar disposed on the top of the slide, which passes through the frame and is slidably connected to it.
[0017] By adopting the above technical solution, the carriage can slide up and down inside the frame.
[0018] Preferably, the pressing part also has a spring nested on the outside of the slide bar, the spring being located between the frame and the slide.
[0019] By adopting the above technical solution, the spring force can be used to push the slide to slide inside the frame.
[0020] Compared with the prior art, the beneficial effects of this utility model are: by providing a glue application part, the sliding displacement of the adjusting shaft inside the glue application roller can be controlled, thereby enabling the adjusting shaft to drive the slider to slide inside the glue storage tank, thereby changing the depth of the glue storage tank and thus changing the amount of glue stored in the glue storage tank.

A motor 210 is mounted on the side of the frame 1. The output end of the motor 210 is connected to the glue application roller 201. The slider 208 and the adjusting shaft 203 are connected by a transmission. The adjusting shaft 203 slides to drive the slider 208 to slide within the glue storage grooves 202, thereby adjusting the glue storage amount. The surface of the glue application roller 201 has twelve glue storage grooves 202, which are centered around the rotation axis of the glue application roller 201. The structure features a rotationally symmetrical design. Each of the twelve glue storage tanks 202 has a sliding slider 208. The amount of glue stored in each tank can be changed by the sliding displacement of the slider 208 within the tank. The pressing part 3 is located inside the frame 1, and a slide 301 is slidably installed inside the frame 1. A pressing roller 304 is rotatably installed inside the slide 301. The pressing roller 304 is located directly above the coating roller 201 and is pressed down to make it abut against the coating roller 201. By controlling the sliding displacement of the adjusting shaft 203 inside the coating roller 201, the adjusting shaft 203 can drive the slider 208 to slide within the glue storage tank 202, thereby changing the depth of the glue storage tank 202 and thus the amount of glue stored in the tank. Example
[0031] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: an adjusting roller for a coating thickness die head, comprising a coating section 2, a coating roller 201, and an adjusting shaft 203.
[0032] A groove 204 is provided inside the adjusting shaft 203. A guide rod 209 is provided at one end of the slider 208. The guide rod 209 is embedded in the groove 204 and slidably connected thereto. The slider 208 can be slidably moved in the glue storage tank 202 by the lateral sliding displacement of the adjusting shaft 203 in the glue coating roller 201. A limit frame 206 is provided on the side of the frame 1. A limit block 207 is slidably provided inside the limit frame 206. One end of the adjusting shaft 203 passes through the limit frame 206 and is rotatably connected thereto. 7. The limiting block 207 is fixed inside the limiting frame 206 by bolts. The bottom semi-circular groove of the limiting block 207 engages with the adjusting shaft 203. The position of the adjusting shaft 203 can be fixed by the limiting block 207. Several limiting grooves 205 are provided at one end of the adjusting shaft 203. The several limiting grooves 205 are annular grooves around the adjusting shaft 203 and engage with the limiting block 207. The position of the adjusting shaft 203 inside the coating roller 201 can be controlled by engaging the limiting block 207 with different limiting grooves 205. Example
[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: an adjusting roller for an adhesive coating thickness die head, comprising a pressing part 3, a slide 301, and a slide bar 302.
[0034] A slide rod 302 is provided on the top of the slide 301. The slide rod 302 passes through the frame 1 and is slidably connected to it, allowing the slide 301 to slide up and down inside the frame 1. A spring 303 is nested on the outside of the slide rod 302. The spring 303 is located between the frame 1 and the slide 301. The elastic force provided by the spring 303 can push the slide 301 to slide inside the frame 1.
[0035] Working principle: First, the device is powered on, and then glue is introduced into the glue storage tank (101) until the glue covers the bottom of the coating roller (201). Then, the motor 210 drives the coating roller (201) to rotate, so that the glue enters the glue storage tank 202 during the rotation of the coating roller (201). Next, the corrugated cardboard passes between the coating roller (201) and the lower pressure roller 304. Under the push of the spring 303, the lower pressure roller 304 will press the corrugated cardboard onto the coating roller (201), so that the glue in the glue storage tank 202 will adhere to the corrugated cardboard, thereby completing the glue application operation. Then, by adjusting the lateral sliding displacement of the adjusting shaft 203 in the coating roller 201, the slider 208 can be driven to slide in the glue storage tank 202, thereby enabling the adjusting shaft 203 to drive the slider. The 208 slides inside the glue storage tank 202, thereby changing the depth of the glue storage tank 202 and thus changing the amount of glue stored in the glue storage tank 202. One end of the adjusting shaft 203 passes through the limiting frame 206 and is rotatably connected to it. The limiting block 207 is fixed inside the limiting frame 206 by bolts. The semi-circular groove at the bottom of the limiting block 207 engages with the adjusting shaft 203. The position of the adjusting shaft 203 can be fixed by the limiting block 207. Several limiting grooves 205 are provided at one end of the adjusting shaft 203. The several limiting grooves 205 are annular grooves around the adjusting shaft 203 and engage with the limiting block 207. The position of the adjusting shaft 203 inside the glue coating roller 201 can be controlled by engaging the limiting block 207 with different limiting grooves 205.
