Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, specifically to an adjustable line-adding device for corrugated cardboard. Background Technology

[0002] Paperboard refers to thick sheets of paper made from various pulps, composed of interwoven fibers. Currently, corrugated paperboard is the most commonly used type. Corrugated paperboard is a multi-layered laminate, consisting of at least one corrugated core layer and one layer of paperboard. It is mainly used for manufacturing cartons, carton fillings, and outer packaging for fragile goods. Corrugated paperboard is less affected by temperature, has good light-blocking properties, and is generally less affected by humidity. During the production process, reinforcing lines, such as metal or plastic lines, are added inside the paperboard to improve its strength or compressive strength. However, some existing corrugated paperboard processing equipment cannot adjust the position and spacing of these reinforcing lines as needed, making it unsuitable for producing multiple paperboard sizes. This results in low equipment versatility, requiring the replacement of appropriate line dividers for different sizes of paperboard with varying reinforcing line distributions, thus reducing production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-8As shown, this utility model provides an adjustable corrugated cardboard creasing device, including a machine housing 1 and a creasing assembly 2. The creasing assembly 2 is installed inside the machine housing 1. The machine housing 1 also houses a conveying roller group and a pressing roller group, used for conveying cardboard and pressing two sheets of cardboard, respectively. The creasing assembly 2 includes a fixing frame 201 and a creasing roller 202. The fixing frame 201 is fixedly installed inside the machine housing 1. Multiple creasing rods 203 are evenly distributed and fixedly installed at the bottom of the fixing frame 201. The tops of the multiple creasing rods 203 are... A cover plate 204 is threadedly installed. A first through groove 208 is formed at the top of the fixing frame 201. Multiple equally spaced wire divider blocks 205 are slidably installed within the first through groove 208. Each wire divider block 205 has a wire-passing hole 212. A rotating roller 207 is rotatably installed on the upper surface of each wire divider block 205. A fastening bolt 206 is threaded into one side of each wire divider block 205. A second through groove 213 is formed on one side of the top of the fixing frame 201, and the fastening bolt 206 can slide along the second through groove 213. The fixing frame 201... A baffle 209 is slidably installed on one side of the top edge of component 1, which can be used to place the reinforcing wire coil onto the insertion rod 203 (the height of the wire coil is lower than the height of the insertion rod 203, and the inner diameter of the paper tube of the wire coil is larger than the diameter of the insertion rod 203). A cover plate 204 is then screwed on to limit the wire coil's position. The position and spacing of multiple wire dividing blocks 205 can be adjusted as needed, and the fastening bolts 206 are tightened to secure them. Then, the reinforcing wire on the wire coil is passed through the wire-passing hole 212 on the wire dividing block 205 and placed on the rotating roller 207. 207 can reduce the friction of the reinforcing lines. The pressure roller 202 can be used to make the reinforcing lines contact the surface of the bottom cardboard, so that multiple reinforcing lines are evenly distributed on the surface of the bottom cardboard. The two cardboards coated with glue are conveyed by the conveying roller group, and the two cardboards are pressed together by the pressing roller group, thereby adding the reinforcing lines between the two cardboards to improve the strength or compressive strength of the cardboard. A baffle 209 is set at one end of the fixed frame 201, which can facilitate the increase or decrease of the number of reinforcing lines as needed.

[0023] Two symmetrically distributed guide rods 210 are fixedly installed on one side of the top of the fixed frame 201, and the guide rods 210 are inserted through the baffle 209. Springs 211 are sleeved on both guide rods 210. When it is necessary to add or remove the dividing block 205, the baffle 209 can be manually pulled up along the guide rod 210 and the springs 211 can be squeezed. After the addition is completed, the baffle 209 is released and the spring force of the spring 211 is used to reset the baffle 209.

[0024] An adjustment component 3 is installed on the outer casing 1 of the machine body. The adjustment component 3 includes two symmetrically distributed slide grooves 301, and the slide grooves 301 are fixedly installed inside the outer casing 1 of the machine body. A slider 302 is slidably installed in each of the two slide grooves 301, and a creasing roller 202 is rotatably installed between the two sliders 302. According to the different thicknesses of the cardboard, the slider 302 drives the creasing roller 202 to slide up and down along the slide groove 301, and the creasing roller 202 can be used to make the reinforcing line contact the surface of the bottom cardboard.

[0025] Both slide grooves 301 are rotatably installed with threaded rods 303, and the threaded rods 303 are threadedly inserted into the corresponding sliders 302. The threaded rods 303 drive the sliders 302 to slide within the slide grooves 301.

[0026] A drive shaft 304 is rotatably mounted on the top of the outer shell 1. Two first bevel gears 305 are fixedly mounted on the drive shaft 304, causing the drive shaft 304 to drive the first bevel gears 305 to rotate.

[0027] The top ends of the two threaded rods 303 are fixedly equipped with second bevel gears 306, and the second bevel gears 306 mesh with the corresponding first bevel gears 305, so that the first bevel gears 305 drive the second bevel gears 306 to rotate, and the second bevel gears 306 drive the threaded rods 303 to rotate.

[0028] A motor 307 is fixedly installed on one side of the top of the outer casing 1, and the output end of the motor 307 is fixedly connected to one end of the drive shaft 304, so that the motor 307 drives the drive shaft 304 to rotate.

[0029] Working Principle: In use, the reinforcing wire coil can be placed on the insertion rod 203, and the cover plate 204 is screwed on to limit the coil and prevent it from falling off the insertion rod 203 when the reinforcing wire is pulled. The number of reinforcing wires can be adjusted by manually pulling up the baffle 209 along the guide rod 210 and squeezing the spring 211 to increase or decrease the number of wire dividing blocks 205. After adding the wires, the baffle 209 is released, and the spring 211 returns it to its original position. Then, the position and spacing of the multiple wire dividing blocks 205 are adjusted as needed, and the fastening bolts 206 are tightened to secure them. The reinforcing wire on the coil is then passed through the threading hole 212 on the wire dividing block 205 and placed on the rotating roller 207. Depending on the thickness of the cardboard, the motor 307 drives the drive shaft 304 to rotate. The drive shaft 304 drives the first bevel gear 305 to rotate, the first bevel gear 305 drives the second bevel gear 306 to rotate, the second bevel gear 306 drives the threaded rod 303 to rotate, the threaded rod 303 drives the slider 302 to slide in the groove 301, the slider 302 drives the pressure roller 202 to slide and rise along the groove 301, the pressure roller 202 makes the reinforcing line contact the surface of the bottom cardboard, so that multiple reinforcing lines are evenly distributed on the surface of the bottom cardboard, and are adhered to the bottom cardboard by the glue on the bottom cardboard. The two conveyor rollers convey the glued cardboard, and the bottom cardboard moves while the reinforcing line is unwound and moves with it. The pressing rollers press the two cardboards together, and the pressed cardboard is conveyed at the same time, thereby adding the reinforcing line between the two cardboards to improve the strength or compressive strength of the cardboard.
