Description

Technical Field

[0001] This utility model belongs to the technical field of paperboard processing equipment, and in particular relates to an adaptive paperboard bonding pressure adjustment mechanism. Background Technology

[0002] According to the published patent CN223252510U, a paperboard bonding device for corrugated cardboard production includes a housing assembly. The housing assembly has a through groove with two sides communicating with each other. The inner walls of the through grooves on both sides have an array of bonding slots that communicate with the outside. Each bonding slot has a bonding component inserted into it. The ends of each row of bonding components away from the through grooves are connected. The bonding components are filled with adhesive. After the device is completed, by pressing down the extrusion block, the bonding slider can slide freely in the bonding slot. Thus, different layers of bonding sliders can be extracted according to the different thicknesses of corrugated cardboard, and bonding work can be performed on corrugated cardboard of different thicknesses. However, the following shortcomings still exist.

[0003] After the above equipment is completed, it can only flexibly extract the adhesive sliders of different layers according to the thickness of the corrugated paper. However, it is difficult to automatically adjust the extrusion pressure according to the degree of extrusion of the corrugated paper when extruding the corrugated paper, which leads to excessive extrusion pressure. This causes the corrugated paper to deform and be damaged due to excessive extrusion pressure, making it difficult to use normally. Therefore, we propose an adaptive cardboard adhesive pressure adjustment mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide an adaptive cardboard bonding pressure adjustment mechanism. Through the adjustment mechanism and the limiting mechanism, it solves the problem that the bonding sliders of different layers can be flexibly extracted according to the thickness of the corrugated paper, but it is difficult to automatically adjust the extrusion pressure according to the degree of extrusion of the corrugated paper when extruding the corrugated paper, which leads to excessive extrusion pressure, causing the corrugated paper to be deformed and damaged due to excessive extrusion pressure, making the corrugated paper unusable.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an adaptive cardboard bonding pressure adjustment mechanism, which includes several support legs. A placement plate is fixedly connected to the top outer wall of the support legs, and an L-plate is fixedly connected to the top outer wall of the placement plate. An adjustment mechanism is provided on the inner wall of the L-plate.

[0007] The adjustment mechanism includes an electric push rod, the outer wall of which is fixedly connected to the inner wall of the L-plate. An output plate is fixedly connected to the output end of the electric push rod. Several sleeves are fixedly connected to the bottom outer wall of the mounting plate. A sliding rod is slidably connected to the inner wall of each sleeve. A spring is fitted onto the outer wall of the sliding rod. A pressure plate is fixedly connected to the outer wall of the sliding rod on the side away from the electric push rod. Several fixing brackets are fixedly connected to the bottom outer wall of the mounting plate. A threaded rod is rotatably connected to the inner wall of each fixing bracket. A fixing plate is threadedly connected to the outer wall of the threaded rod. A circular groove is formed on the inner wall of the fixing plate, and a guide rod is slidably connected to the inner wall of the circular groove.

[0008] Furthermore, the outer wall of the guide rod is fixedly connected to the inner wall of the fixing frame, a round rod is fixedly connected to the inner wall of the fixing plate, a grooved plate is slidably connected to the outer wall of the sliding rod, a number of triangular plates are fixedly connected to the top outer wall of the grooved plate, an inclined groove is opened on the inner wall of the triangular plate, the inner wall of the inclined groove is slidably connected to the outer wall of the round rod, and a limit mechanism is provided on the bottom outer wall of the placement plate.

[0009] Furthermore, the limiting mechanism includes a support frame, the outer wall of which is fixedly connected to the bottom outer wall of the placement plate, and the inner wall of the support frame is rotatably connected to a rotating shaft.

[0010] Furthermore, a crown gear is fixedly connected to the outer wall of the rotating shaft on the side away from the support frame, and a roller is rotatably connected to the inner wall of the placement plate.

[0011] Furthermore, a gear is fixedly connected to the outer wall of the roller near the crown gear, and a mounting bracket is fixedly connected to the outer wall of the roller.

[0012] Furthermore, the inner wall of the mounting frame is fixedly connected to several rotating rods, and the outer wall of the rotating rods is rotatably connected to connecting rods.

[0013] Furthermore, a rolling rod is rotatably connected to the inner wall of the end of the connecting rod away from the rotating rod, and several sliding grooves are provided on the inner wall of the placement plate.

[0014] Furthermore, a slider is slidably connected to the inner wall of the groove, the bottom outer wall of the slider is fixedly connected to the outer wall of the rolling rod, and a limit plate is fixedly connected to the top outer wall of the slider.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a spring and a grooved plate. When the threaded rod rotates, the fixed plate slides on the guide rod, while the fixed plate moves along with the round rod. As the round rod moves, it slides in the inclined groove, and simultaneously, the round rod presses against the triangular plate, causing the triangular plate to move. As the triangular plate moves, it moves along with the grooved plate, which then slides on the surface of the sliding rod. This improves the flexibility of the equipment. During cardboard extrusion, the extrusion force can be automatically adjusted according to the degree of extrusion, preventing excessive extrusion force from causing deformation and damage to the cardboard. Furthermore, the spring preload can be flexibly adjusted according to the cardboard thickness, allowing the equipment to adapt to cardboard of different thicknesses and preventing the extrusion process from being too tight or too loose due to an unsuitable spring preload.

[0017] 2. This utility model incorporates a connecting rod and a limiting plate. When the roller rotates, it carries the mounting frame to rotate as well. The mounting frame then carries the rotating rod in a circular motion. As the rotating rod moves, it carries the connecting rod in an arc motion. The connecting rod then carries the rolling rod to move. As the rolling rod moves, it carries the slider to slide in the groove. Simultaneously, the slider carries the limiting plate to move, bringing the limiting plate closer to the cardboard. This improves the bonding accuracy. When bonding different cardboards, it can limit them to the designated positions on the equipment, preventing displacement deviations during the extrusion and bonding process, resulting in more precise and neat bonding of different cardboards.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 As shown, this utility model is an adaptive cardboard bonding pressure adjustment mechanism, including several support legs 1. A placement plate 101 is fixedly connected to the top outer wall of the support leg 1. An L plate 102 is fixedly connected to the top outer wall of the placement plate 101. An adjustment mechanism 2 is provided on the inner wall of the L plate 102.

[0030] Adjustment mechanism 2 includes an electric push rod 201. The operator starts the electric push rod 201. The outer wall of the electric push rod 201 is fixedly connected to the inner wall of the L-plate 102. An installation plate 202 is fixedly connected to the output end of the electric push rod 201. Several sleeves 203 are fixedly connected to the bottom outer wall of the installation plate 202. After the electric push rod 201 is started, it pushes the installation plate 202 to move, and then the installation plate 202 moves along with the sleeves 203, realizing the kinetic energy transfer process between parts. A sliding rod 204 is slidably connected to the inner wall of the sleeve 203. When the sliding rod 204 slides in the sleeve 203, it will not swing, keeping it moving horizontally. A spring 205 is sleeved on the outer wall of the sliding rod 204. When the spring 205 is compressed on the sliding rod 204, it will not swing. The spring 205 is misaligned to ensure normal operation. A pressure plate 206 is fixedly connected to the outer wall of the sliding rod 204 away from the electric push rod 201. Several fixing brackets 207 are fixedly connected to the bottom outer wall of the mounting plate 202. When the threaded rod 208 rotates in the fixing bracket 207, the threaded rod 208 will not swing, ensuring smooth operation. The threaded rod 208 is rotatably connected to the inner wall of the fixing bracket 207. A fixing plate 209 is threadedly connected to the outer wall of the threaded rod 208. A circular groove 210 is opened on the inner wall of the fixing plate 209. A guide rod 211 is slidably connected to the inner wall of the circular groove 210. When the threaded rod 208 rotates, the fixing plate 209 will slide on the guide rod 211. The guide rod 211 limits the fixing plate 209, preventing it from rotating with the threaded rod 208.

[0031] The outer wall of the guide rod 211 is fixedly connected to the inner wall of the fixing frame 207. A round rod 212 is fixedly connected to the inner wall of the fixing plate 209. When the fixing plate 209 moves, it will move the round rod 212, realizing the kinetic energy transfer process between the parts. A grooved plate 213 is slidably connected to the outer wall of the sliding rod 204. Several triangular plates 214 are fixedly connected to the top outer wall of the grooved plate 213. An inclined groove 215 is opened on the inner wall of the triangular plate 214. The inner wall of the inclined groove 215 is slidably connected to the outer wall of the round rod 212. When the round rod 212 moves, it will slide in the inclined groove 215. At the same time, the round rod 212 will squeeze the triangular plate 214, causing the triangular plate 214 to move. When the triangular plate 214 moves, it will move the grooved plate 212. The movement of the slot plate 213 realizes the kinetic energy transfer process between parts. The bottom outer wall of the placement plate 101 is provided with a limiting mechanism 3. The limiting mechanism 3 includes a support frame 301. The outer wall of the support frame 301 is fixedly connected to the bottom outer wall of the placement plate 101. The inner wall of the support frame 301 is rotatably connected to a rotating shaft 302. When the rotating shaft 302 rotates in the support frame 301, the rotating shaft 302 will not swing, so that the rotating shaft 302 keeps running smoothly. The outer wall of the rotating shaft 302 away from the support frame 301 is fixedly connected to a crown gear 303. The inner wall of the placement plate 101 is rotatably connected to a roller 304. When the rotating shaft 302 rotates, it will drive the crown gear 303 to rotate, thus completing the kinetic energy transfer process between parts.

[0032] A gear 305 is fixedly connected to the outer wall of the roller 304 near the crown gear 303. A mounting bracket 306 is fixedly connected to the outer wall of the roller 304. Several rotating rods 307 are fixedly connected to the inner wall of the mounting bracket 306. When the crown gear 303 rotates, it will drive the gear 305 to rotate, and then the gear 305 will drive the roller 304 to rotate. At the same time, the roller 304 will drive the mounting bracket 306 to rotate, and then the mounting bracket 306 will drive the rotating rods 307 to rotate in a circular motion, completing the kinetic energy transfer process between the parts. A connecting rod 308 is rotatably connected to the outer wall of the rotating rod 307, and a roller is rotatably connected to the inner wall of the connecting rod 308 away from the rotating rod 307. The moving rod 309, when the rotating rod 307 moves, will cause the connecting rod 308 to move in an arc. Then the connecting rod 308 will move the rolling rod 309, completing the kinetic energy transfer process between the parts. The inner wall of the placement plate 101 is provided with several sliding grooves 310. The inner wall of the sliding groove 310 is slidably connected to the slider 311. The bottom outer wall of the slider 311 is fixedly connected to the outer wall of the rolling rod 309. The top outer wall of the slider 311 is fixedly connected to the limiting plate 312. When the rolling rod 309 moves, it will cause the slider 311 to slide in the sliding groove 310. Then the slider 311 will move with the limiting plate 312, realizing the kinetic energy transfer between the parts.

[0033] One specific application of this embodiment is:

[0034] When the operator needs to use the equipment, first, different cardboard pieces are placed on the placement plate 101, and glue is applied between them. Then, the cardboard pieces are positioned between multiple limiting plates 312. After the cardboard pieces are placed, the operator rotates the rotating shaft 302. As the rotating shaft 302 rotates, it drives the crown gear 303 to rotate. As the crown gear 303 rotates, it drives the gear 305 to rotate. As the gear 305 rotates, it drives the roller 304 to rotate. As the roller 304 rotates, it drives the mounting bracket 306 to rotate. The mounting bracket 306 then drives the rotating rod 307 to move in a circular motion. As the rotating rod 307 moves, it drives the connecting rod 308 to move in an arc. The connecting rod 308 then drives the rolling rod... As the roller 309 moves, it carries the slider 311, which slides within the groove 310. Simultaneously, the slider 311 moves the limiting plate 312, bringing it closer to the cardboard. The limiting plate 312 then holds the cardboard in a fixed position, preventing displacement or misalignment during pressing and ensuring precise bonding. After the cardboard is placed, the operator activates the electric push rod 201. This activates the mounting plate 202, which in turn moves the sleeve 203. The movement of the sleeve 203, via the spring force of the spring 205, causes the pressure plate 206 to move as well. The sliding rod 204 moves along with the pressure plate 206. When the pressure plate 206 moves, it contacts the cardboard. As the pressure plate 206 continues to move, it presses the different cardboards together. Once the cardboards are pressed together, the pressure plate 206 stops moving. Then, as the sleeve 203 continues to move, it compresses the spring 205. At the same time, the sliding rod 204 slides within the sleeve 203. The contraction of the spring 205 prevents the pressure plate 206 from moving too far and causing the cardboards to be pressed too tightly, thus preventing the cardboard from being flattened. The operator can adjust the preload of the spring 205 according to the thickness of the cardboard. During adjustment, the operator can rotate the threaded rod 208. When the groove rod 208 rotates, the fixed plate 209 slides on the guide rod 211. At the same time, the fixed plate 209 moves the round rod 212. When the round rod 212 moves, it slides in the inclined groove 215. Simultaneously, the round rod 212 presses the triangular plate 214, causing the triangular plate 214 to move. When the triangular plate 214 moves, it moves the grooved plate 213. Then, the grooved plate 213 slides on the surface of the sliding rod 204. At the same time, the grooved plate 213 pre-compresses the spring 205, changing the preload value of the spring 205. This allows the equipment to be used with cardboard of different thicknesses, avoiding situations where the preload value of the spring 205 is unsuitable for the cardboard thickness, resulting in poor or excessive pressing during cardboard pressing.
