Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, and in particular relates to a single-facer for preparing packaging boxes. Background Technology

[0002] In the packaging industry, corrugated cardboard is the core material for making various packaging boxes, and the single-facer (also known as a corrugated forming machine) is one of the key pieces of equipment on the corrugated cardboard production line. Its main function is to combine base paper and corrugated paper through processes such as heating, gluing, and corrugating to form corrugated cardboard with a single layer of paper, laying the foundation for subsequent compounding with other cardboard to form multi-layer corrugated cardboard. The single-facer for packaging box preparation is the core equipment on the corrugated cardboard production line. Its main function is to process the face paper and the corrugated base paper through a series of processes to form a single-face corrugated cardboard, which provides the basic material for the subsequent production of multi-layer corrugated cardboard and various packaging boxes. Different types of corrugated rolls need to be replaced according to production needs, especially when producing corrugated cardboard of different specifications. However, the corrugated rolls in existing equipment are usually fixed with bolts, which is difficult to disassemble, resulting in long-term downtime of the equipment and affecting production efficiency. Therefore, we propose a single-facer for packaging box preparation. Utility Model Content

Through the quick-release mechanism and the glue coating mechanism, it solves the problem that different types of corrugated rollers need to be replaced according to production needs, especially when producing corrugated cardboard of different specifications. However, the corrugated rollers in the existing equipment are usually fixed with bolts, which is difficult to disassemble, resulting in long-term downtime of the equipment and affecting production efficiency.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a single-facer for preparing packaging boxes, including a base plate, a single-facer fixedly connected to the top outer wall of the base plate, an unwinding roller rotatably connected to the top inner wall of the single-facer, a plurality of conveying rollers rotatably connected to the inner wall of the single-facer, and a quick-release mechanism provided on the inner wall of the single-facer. The quick-release mechanism includes a fixing plate, the outer wall of which is fixedly connected to the outer wall of the single-sided machine. A self-locking motor is fixedly connected to the outer wall of the fixing plate. A connecting sleeve is fixedly connected to the bottom output end of the self-locking motor via a coupling. Several connecting sleeves are rotatably connected to the inner wall of the single-sided machine. Corrugated rollers are contacted on the inner walls of the connecting sleeves. Hollow inserts are inserted into the inner walls of the corrugated rollers and connecting sleeves. Lead screws are threadedly connected to the inner walls of the hollow inserts. Extrusion blocks are fixedly connected to the bottom outer walls of the lead screws. An adhesive applicator is provided on the top outer wall of the single-sided machine.

[0005] Furthermore, each of the hollow inserts has a positioning plate fixedly connected to its inner wall, a limiting slide rod slidably connected to the inner wall of each positioning plate, a sliding groove formed on the inner wall of each hollow insert, the inner wall of each sliding groove slidably connected to the outer wall of the limiting slide rod near the positioning plate, the outer wall of the limiting slide rod away from the positioning plate contacts the outer wall of the extrusion block, and a spring is sleeved on the outer wall of each limiting slide rod.

[0006] Furthermore, the glue coating mechanism includes a glue storage tank, the bottom outer wall of which is fixedly connected to the top outer wall of the single-sided machine, a stirring shaft is rotatably connected to the inner wall of the glue storage tank, a water pump is fixedly connected to the outer wall of the glue storage tank, a connecting pipe is fixedly connected to the bottom output end of the water pump, the outer wall of the connecting pipe away from the water pump is fixedly connected to the inner wall of the glue storage tank, and a transmission pipe is fixedly connected to the inner wall of the water pump away from the connecting pipe.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a spring that rebounds, causing the limiting slide rod to reset. The reset limiting slide rod then retracts the end of the hollow insert rod that was originally outside the hollow insert rod through a sliding groove into the hollow insert rod. This allows the hollow insert rod to be pulled out from the connecting sleeve and the corrugated roller, enabling the corrugated roller to be replaced. This achieves rapid replacement of the corrugated roller, significantly reducing downtime, minimizing production interruptions, and improving production line efficiency.

[0013] 2. This utility model incorporates a water pump. When the water pump starts working, it draws glue stored in the glue tank through a connecting pipe and then transmits it to a transmission pipe for spraying through a nozzle. The glue is sprayed onto the surface of the coating roller. At this point, the controller starts the first motor, which drives the coating roller to rotate. The coating roller then applies the glue to the surface of the paper core, achieving the effect of coating the paper core surface. This is a key step in improving the strength, durability, and appearance of the cardboard, effectively increasing production efficiency and reducing material waste.

[0019] Please see Figure 1-5 As shown, this utility model is a single-facer for packaging box preparation, including a base plate 1, a single-facer 101 fixedly connected to the top outer wall of the base plate 1, and an unwinding roller 102 rotatably connected to the top inner wall of the single-facer 101. The unwinding roller 102 is used to fix the paper core, thereby facilitating the conveying of the paper core. Several conveying rollers 103 are rotatably connected to the inner wall of the single-facer 101. The conveying rollers 103 are used to convey the paper core to a suitable position for subsequent operations. A quick-release mechanism 2 is provided on the inner wall of the single-facer 101. The quick-release mechanism 2 includes a fixing plate 201. The outer wall of the fixing plate 201 is fixedly connected to the outer wall of the single-sided machine 101. A self-locking motor 202 is fixedly connected to the outer wall of the fixing plate 201. The fixing plate 201 is used to support and fix the self-locking motor 202, thereby making it more stable during operation. The bottom output end of the self-locking motor 202 is fixedly connected to a connecting sleeve 203 through a coupling. Several connecting sleeves 203 are rotatably connected to the inner wall of the single-sided machine 101. The inner walls of the several connecting sleeves 203 are all in contact with corrugated rollers 204. When the self-locking motor 202... When rotated, the connecting sleeve 203 rotates, which in turn drives the corrugated roller 204 to rotate. Hollow insert rods 205 are inserted into the inner wall of several corrugated rollers 204 and the connecting sleeve 203. Screws 206 are threadedly connected to the inner wall of several hollow insert rods 205. Extrusion blocks 207 are fixedly connected to the bottom outer wall of several screws 206. When the screws 206 rotate, they will move upward in the hollow insert rods 205. When moving, they drive the extrusion blocks 207 to move in the same direction. The top outer wall of the single-sided machine 101 is provided with a glue application mechanism 3. A number of hollow insert rods 205 are fixedly connected to their inner walls with positioning plates 208. A limiting slide rod 209 is slidably connected to the inner walls of the positioning plates 208. The limiting slide rod 209 is used to limit the corrugated roller 204, thus preventing it from falling off during use. A groove 211 is formed on the inner wall of each hollow insert rod 205. The inner wall of each groove 211 is slidably connected to the outer wall of the limiting slide rod 209 near the positioning plate 208. The outer wall of the limiting slide bar 209 away from the positioning plate 208 is in contact with the outer wall of the extrusion block 207. The extrusion block 207 presses the limiting slide bar 209, causing it to move, thereby moving one end to the outside of the hollow insert rod 205 to limit and fix the corrugated roller 204. The outer walls of several limiting slide bars 209 are fitted with springs 212. The glue coating mechanism 3 includes a glue storage tank 301. The bottom outer wall of the glue storage tank 301 is in contact with the top of the single-facer 101. A stirring shaft 302 is rotatably connected to the inner wall of the glue storage tank 301, which is fixedly connected to the outer wall. The stirring shaft 302 is used to stir the glue in the glue storage tank 301 to prevent it from solidifying and affecting subsequent glue application. A water pump 303 is fixedly connected to the outer wall of the glue storage tank 301. A connecting pipe 304 is fixedly connected to the bottom output end of the water pump 303. The outer wall of the connecting pipe 304 away from the water pump 303 is fixedly connected to the inner wall of the glue storage tank 301. A transmission pipe 305 is fixedly connected to the inner wall of the water pump 303 away from the connecting pipe 304. The water pump 303 draws glue from the glue storage tank 301 through the connecting pipe 304 and then transmits it to the transmission pipe 305. The outer wall of the transmission pipe 305 is fixedly connected to the inner wall of the single-sided machine 101. A nozzle 306 is fixedly connected to the inner wall of the transmission pipe 305. The glue transmitted to the transmission pipe 305 is sprayed through the nozzle 306 so that it can be sprayed onto subsequent parts. A fixing plate 307 is fixedly connected to the outer wall of the single-facer 101. A first motor 308 is fixedly connected to the outer wall of the fixing plate 307. A glue-applying roller 309 is fixedly connected to the bottom output end of the first motor 308 via a coupling. When the first motor 308 runs, it drives the glue-applying roller 309 to rotate. When the glue-applying roller 309 rotates, it applies glue to the surface of the paper core. The outer wall of the glue-applying roller 309 is rotatably connected to the outer wall of the single-facer 101. A pulley 310 is fixedly connected to the outer wall of the glue-applying roller 309. A belt 311 is driven to the outer wall of the pulley 310. A second pulley 312 is driven to the outer wall of the belt 311. The inner wall of the second pulley 312 is fixedly connected to the inner wall of the stirring shaft 302. When the pulley 310 rotates, it drives the belt 311 to rotate. At this time, the belt 311 drives the second pulley 312 to rotate. After the second pulley 312 rotates, it drives the stirring shaft 302 to rotate, thereby stirring the glue.

[0020] One specific application of this embodiment is: When the operator needs to use the equipment, firstly, the paper core on the unwinding roller 102 is placed on 103 and pulled into the corrugated roller 204. Then, the self-locking motor 202 is started via the controller. When the self-locking motor 202 starts running, it drives the connecting sleeve 203 to rotate. When the connecting sleeve 203 rotates, it drives the corrugated roller 204 to rotate. After the corrugated roller 204 rotates, it squeezes the paper core. Through continuous squeezing, the paper core is pressed into the corresponding corrugated shape and conveyed forward. When it is necessary to change to a different corrugated roller 204, firstly, the lead screw 206 is rotated. When the lead screw 206 rotates, it will... The hollow insert rod 205 moves upward, simultaneously moving the pressing block 207. When the pressing block 207 moves upward a certain distance, it releases the pressure on the limiting slide rod 209. At this time, the limiting slide rod 209 simultaneously releases the pressure on the spring 212, and then the spring 212 begins to rebound. The rebound force of the spring 212 drives the limiting slide rod 209 to reset. After resetting, the limiting slide rod 209 will retract the end that was originally outside the hollow insert rod 205 into the hollow insert rod 205 through the sliding groove 211. At this point, the hollow insert rod 205 can be removed from the connecting sleeve 2. 03 is removed from the corrugated roll 204, and then the corrugated roll 204 can be replaced. When the processed paper core moves to below the glue coating roll 309, the glue coating roll 309 will apply glue to its edges. Before the glue application begins, some operations are required. First, the water pump 303 is started by the controller. When the water pump 303 starts working, it will draw the glue stored in the glue storage tank 301 through the connecting pipe 304, and then transfer it to the transfer pipe 305 and spray it through the nozzle 306. At this time, the glue will be sprayed onto the surface of the glue coating roll 309. Then, the first... When the first motor 308 starts running, it drives the glue-applying roller 309 to rotate. At this time, the glue-applying roller 309 applies glue to the edge of the paper core. When the glue-applying roller 309 rotates, it synchronously drives the pulley 310 to rotate. At this time, the pulley 310 drives the second pulley 312 to rotate through the belt 311. When the second pulley 312 rotates, it drives the stirring shaft 302 to rotate. When the stirring shaft 302 rotates, it stirs the glue in the glue storage tank 301, thereby preventing the glue from solidifying and affecting the glue-applying effect. After the glue-applying paper core is completed, it will be conveyed forward for subsequent operations.
