[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0025] Example 1: Figures 1-13 As shown, this embodiment provides a corrugated cardboard production gluing device, including a bracket 1, and also includes a gluing mechanism 2 on the bracket 1, and a glue storage mechanism 3 is provided on one side of the bracket 1; the gluing mechanism 2 includes a rubber roller 201 provided on the bracket 1, and a glue pool 207 is provided at the bottom of the rubber roller 201, and two groups of glue injection pipes 208 are connected through the bottom of the glue pool 207, and a pool bottom 209 is provided below the glue pool 207, and the pool bottom 209 is arc-shaped and concavely engages with the rubber roller 201, and the gluing mechanism 2 also includes a recovery component 21, a glue pressing component 22 and a temporary storage component 23 provided on the glue pool 207; the glue storage mechanism 3 includes a glue storage tank 301 provided on one side of the bracket 1, and the glue storage mechanism 3 also includes a glue squeezing component 31, an air storage component 32, a liquid storage component 33 and a cooling component 34 provided under the glue storage tank 301.

[0026] The gluing mechanism 2 also includes two groups of clamping rollers 202 movably connected to the top of the bracket 1. The top of the two groups of clamping rollers 202 is provided with a cylinder a203, one side of the clamping roller 202 is provided with an electric heating roller 204, one side of the electric heating roller 204 is provided with a guide roller 205, one side of the glue roller 201 is provided with a scraper 206, the bottom of the scraper 206 is provided with two groups of deflection seats 2061, and the two groups of deflection seats 2061 are provided with cylinders b2062.

[0027] In this embodiment, the cylinder a203 drives the two ends of the upper clamping roller 202 to move downward to adjust the distance between the two sets of clamping rollers 202, thereby realizing the pressure-bonding of the cardboard. After the pressure is applied, the resistance heat in the electric heating roller 204 is used to quickly dry the glue on the cardboard, and finally it is sent out after being guided by the guide roller 205. When applying glue, the scraper 206 can adjust the degree of adhesion and angle with the cardboard on the glue roller 201 through the adjustment components on the two sets of deflection seats 2061 and the cylinder b2062 to evenly apply the glue on the cardboard.

[0029] In this embodiment, two sets of bidirectional screw rods 211 are driven by pulley a212, and the threaded connection of the nut 213 drives the two sets of top strips 214 and the lower elastic scraper strips 215 to move inward synchronously during rotation. During the displacement process, the elastic scraper strips 215 are affected by the elastic parts in the telescopic plate 216, so that the elastic scraper strips 215 can always contact the bottom wall of the glue pool 207, so that the adhered glue can be scraped to the center of the pool bottom 209 for recovery during movement.

[0030] The glue pressing assembly 22 includes: a bottom groove tube 221, which is connected to the bottom of the pool 209; a worm 222, which is arranged at the center of the bidirectional screw 211; a worm wheel 223, which is arranged under the worm 222; a cam 224, which is arranged at one end of the worm wheel 223; a track plate 225, with two groups of track plates 225 fixedly connected to the inner wall of the glue pool 207; a connecting rod 226, which is arranged on the cam 224; a slider 227, which is movably connected to the track of the track plate 225; a movable plate 228, which is fixedly connected to the slider 227; and a pressure strip 229, which is arranged under the movable plate 228.

[0031] In this embodiment, the bottom groove tube 221 collects the recycled glue. When the two sets of bidirectional screw rods 211 rotate, the cam 224 on the worm gear 223 is driven to rotate through the worm 222, and the movable plate 228 on the slider 227 is driven to rise and fall along the track on the track plate 225 through the connecting rod 226 on the cam 224, thereby driving the pressure strip 229 to reciprocate and squeeze on the bottom groove tube 221, and squeezing the glue collected in the bottom groove tube 221 through pressure.

[0032] The temporary storage component 23 includes: a glue storage tank 231, which is located under the glue pool 207; a limiting wall ring 2311, which is located on the inner wall of the glue storage tank 231; a pressure gauge 2312, which is located on the glue storage tank 231; a guide pipe 232, which is connected to the glue storage tank 231; a lower glue pipe 233, which is connected to the bottom of the bottom groove pipe 221; an inflation pipe 234, The inflation tube 234 is connected to one end of the guide tube 232; the air hole bottom plate 235 is fixedly connected to the bottom end of the glue storage tank 231; the telescopic rod 236 is arranged on the air hole bottom plate 235; the spring 237 is arranged on the outside of the telescopic rod 236; the piston plate 238 is arranged at the bottom end of the telescopic rod 236; the heat dissipation outer tank 239 is arranged on the outside of the glue storage tank 231.

[0033] In this embodiment, the glue discharged from the bottom trough tube 221 is sent to the guide tube 232 through multiple groups of lower glue hoses 233, and is filled with inert gas through the inflation tube 234. The glue in the guide tube 232 is sent to the upper end of the inner cavity of the glue storage tank 231, that is, the piston plate 238, by air pressure. Under the influence of gravity, the piston plate 238 will overcome the rebound force of the spring 237 and decrease, so that the glue can be stored. Through contact with the inert gas and the low temperature of the coolant in the heat dissipation outer tank 239, oxygen is isolated, the curing of the glue is delayed, and the reaction activity of the borax component in the glue is maintained.

[0034] Example 2: Figure 14-Figure 25 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below.

[0044] Working steps Step 1: Glue preparation and coating process: Put the glue raw material into the glue storage tank 301 through the upper hatch of the glue storage tank 301, and use the motor a302 to drive the ribbon plate 304 and the scraping bottom plate 305 to rotate to achieve the fusion of the raw materials and the preparation of glue. Then, the glue is controlled to enter the glue extrusion tank 311 from the glue inlet pipe 312 through the glue outlet pipe 306. The motor b313 is energized to drive the outer spiral blade 315 of the rotating shaft b314 to rotate and squeeze the glue from the glue outlet nozzle 318 into the glue pool 207; During glue extrusion, when the glue passes through the vacant end 316, it is divided by the multi-component cutter 317, forming multiple gaps. The liquid storage tank 331 can inject borax solution from the tee pipe 332 into the annular pipe 333 via a pump, and finally spray it out from the multiple groups of liquid outlet nozzles 335 on the liquid outlet pipe 334. The liquid outlet pipe 334 is arranged behind the multi-component cutter 317, so that the borax solution can be sprayed onto the divided glue gaps, thereby increasing the contact surface between the borax solution and the glue, improving the fusion effect, and improving the glue solidification efficiency through the borax. The cardboard passes through the rubber roller 201, the nip roller 202, the electric heating roller 204 and the guide roller 205 in sequence. The cardboard is driven by the motor on the rubber roller 201 and adheres to the glue when passing through the glue pool 207. The glue is evenly spread by the scraper 206. The two sets of nip rollers 202 apply pressure to the cardboard. The resistance heat in the electric heating roller 204 quickly dries the glue on the cardboard. Finally, the cardboard is guided by the guide roller 205 and sent out to complete the gluing. Step 2: Shutdown and recovery process: When the equipment is shut down, the valves on the multiple sets of lower rubber hoses 233 below the bottom trough pipe 221 are opened, and the glue in the glue pool 207 flows along the multiple sets of lower rubber hoses 233 and enters the guide pipe 232 for recovery; During recycling, the motor c348 drives the two sets of bidirectional screw rods 211 to rotate synchronously through the pulley b3483 on the rotating shaft c3481 and the pulley a212 on the two sets of bidirectional screw rods 211. The threaded connection of the nut 213 drives the elastic scraping strips 215 under the two sets of top strips 214 to move synchronously inward during rotation. During the displacement process, the elastic scraping strips 215 are affected by the elastic parts in the telescopic plate 216, so that the elastic scraping strips 215 can always contact the bottom wall of the glue pool 207, so that the adhered glue can be scraped to the center of the pool bottom 209 during movement to complete the recycling. During recycling, the worm 222 on the two sets of bidirectional screws 211 drives the worm gear 223 to drive the upper cam 224 to rotate, and the connecting rod 226 on the cam 224 drives the movable plate 228 on the slider 227 to reciprocate along the track on the track plate 225, thereby driving the pressure strip 229 to reciprocate on the bottom groove tube 221, and squeezing the glue collected in the bottom groove tube 221 through pressure; When the recycling is completed, the glue will fill the guide tube 232. The valves of the air outlet pipe 323 and the air filling pipe 234 on the gas tank 321 are opened. The nitrogen in the gas tank 321 is quickly filled to one end of the guide tube 232. The glue in the guide tube 232 is sent to the upper end of the inner cavity of the glue storage tank 231, that is, the piston plate 238. Under the influence of gravity, the piston plate 238 will overcome the rebound force of the spring 237 and fall down, so that the glue can be stored. Step 3: Delaying the curing process: When the machine is shut down, the user closes the valves on the liquid supply of the liquid storage tank 331 and the glue outlet nozzle 318, so that the glue in each unit is stored separately. The borax solution exists in the glue squeezing tank 311 and cannot come into contact with the glue in the glue storage tank 301. This reduces the curing speed of the glue in the largest storage unit without affecting the normal curing of the glue. Nitrogen can be injected into the glue storage tank 301, the glue storage tank 231 and the glue squeezing tank 311 respectively through the gas outlet pipe 323 on the gas tank 321. The inert gas contact can isolate oxygen and moisture, greatly slowing down the curing speed of the glue and effectively preserving the reactivity of the borax solution. The coolant in the cooling station 341 can be injected into the serpentine cooling pipe 344, the heat dissipation outer tank 239 and the outer tank of the glue extrusion tank 311 through the circulation pump 342 and the two-way pipe 343, so as to cool the glue in each unit, and cool the borax solution in the liquid storage tank 331 through heat exchange of multiple groups of fins 346 running through the liquid storage tank 331, thereby further delaying the curing speed of the glue.
