Description

Technical Field

[0001] This utility model relates to the technical field of guide roller suction and transfer devices, specifically a guide roller suction and transfer device for a linerboard paper machine. Background Technology

[0002] Corrugated cardboard is mainly bonded to corrugated paper cores to form corrugated boxes, used for packaging household appliances, daily necessities, textiles, stationery, and the outer packaging of Chinese and Western medicines. During the operation of corrugated cardboard machines, guide rollers and suction devices are typically used to drive the equipment, ensuring stable cardboard transport and preventing slippage. Vacuum rollers, also called vacuum adsorption rollers, are adsorption rollers used in film winding and unwinding equipment. Unlike ordinary double-sided rollers, vacuum rollers have suction holes penetrating the roller surface, and suction elements are located inside the roller. These elements have suction ports facing the inner wall of the roller. As the roller rotates relative to the suction elements, the suction holes on the roller surface periodically pass through the suction ports of the suction elements.

[0003] For example, a Chinese authorized patent, publication number CN213804616U, describes a vacuum suction roller for a papermaking machine. The roller body has evenly distributed perforations, and suction ports are located at both ends inside the roller body. A vacuum chamber is located inside the roller body, and an adjusting screw is mounted on the vacuum chamber. A spraying device is located inside the roller body near the suction ports. This invention, employing the above structure, dilutes the filler material in the suction area after water is sprayed out, allowing the filler to be carried away by the vacuum system. This prevents filler accumulation and suction blockage, ensuring the normal operation of the vacuum suction roller. The pressurized nozzle allows the sprayed water to reach a greater distance, achieving a better dilution effect and facilitating the removal of the filler.

[0004] The aforementioned traditional vacuum suction rollers are prone to causing the linerboard to shift during use. This shifted linerboard can affect the forming effect of the equipment, reduce its aesthetics, and cause operational obstacles, especially during processes such as plate mounting, inking, printing, and paper feeding.

[0027] 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.

[0028] Example

[0029] Reference Figure 1-6 As shown, a guide roller suction device for a linerboard machine includes a roller body 1 and several sets of first holes 211 formed on the outer wall of the roller body 1. Fixed plates 212 are fixed at both ends of the roller body 1. A movable plate 213 corresponding to the fixed plate 212 is sleeved on the outer wall of the roller body 1. A toothed plate 221 is fixed on the outer wall of the movable plate 213 and penetrates the interior of the fixed plate 212. A drive mechanism is provided on the outer wall of the fixed plate 212 to drive the toothed plate 221 to move laterally and reciprocally. The drive mechanism drives the movable plate 213 to move closer to or away from the fixed plate 212. When the movable plate 213 moves away from the fixed plate 212, it can adhere the linerboard on the roller body 1 to achieve the purpose of protection and can be used to guide the linerboard to be transported flat. When the movable plate 213 moves closer to the fixed plate 212, it can be used to adjust the linerboard with a larger width for transport, achieving the purpose of multiple width adjustments. A sealing layer 214 is fixed to the inner wall of the movable plate 213. The sealing layer 214 is in contact with the outer wall of the roller body 1. The sealing layer 214 can be made of rubber. The sealing layer 214 has good wear resistance and can also achieve good sealing effect, preventing the boxboard paper from shifting and enhancing the stability of boxboard paper transportation.

[0030] The drive mechanism includes a first connecting plate 222, an adjusting motor 223, a rotating rod 224, and a rotating gear 225. The first connecting plate 222 is fixed to the outer wall of the fixed plate 212. The adjusting motor 223 is installed on the outer wall of the first connecting plate 222 and its output end is connected to the rotating rod 224. The end of the rotating rod 224 away from the adjusting motor 223 is fixed with a rotating gear 225 that meshes with the rack plate 221. By turning on the adjusting motor 223, the rotating rod 224 and the rotating gear 225 are driven to rotate. The rotating gear 225 drives the rack plate 221 to move the movable plate 213 laterally back and forth, thereby achieving the purpose of automated adjustment and facilitating the transportation of cardboard of different widths.

[0031] The guide roller suction device also includes two sets of brackets 215. The two ends of the roller body 1 are rotatably connected to opposite sides of the two sets of brackets 215. A drive motor 216 is installed on the outer wall of any set of brackets 215, and a vacuum pump 217 is installed on the outer wall of the other set of brackets 215. The output end of the drive motor 216 is connected to the roller body 1, and the output end of the vacuum pump 217 is connected to an input pipe 220 located inside the roller body 1 and an output pipe 218. By turning on the drive motor 216, the roller body 1 is driven to rotate, thereby achieving the purpose of conveying the boxboard paper. By turning on the vacuum pump 217, outside air enters the inside of the roller body 1 through the first hole 211 and is conveyed outward through the vacuum pump 217 and the output pipe 218, so that the outer wall of the roller body 1 generates suction force, which can adsorb the boxboard paper.

[0032] A movable block 226 is fixed at the bottom of the bracket 215. A sliding groove 227 is provided inside the movable block 226. The movable block 226 can be slidably connected to the machine tool through the sliding groove 227. The roller 1 is moved on the machine tool by electric drive through the hydraulic rod to achieve the purpose of horizontal conveying.

[0033] A second connecting plate 314 is fixed to the inner wall of the input pipe 220. The second connecting plate 314 has several sets of second holes 315 inside, the diameter of which is smaller than the diameter of the first hole 211, allowing for the filtration of impurities. An mounting plate 219 is installed on the inner wall of the roller body 1. The outer wall of the mounting plate 219 is rotatably connected to the vacuum pump 217, ensuring that the vacuum pump 217 does not rotate when the roller body 1 rotates. A fixing ring 311 is fixed to the outer wall of the mounting plate 219, and a mounting block 312 is fixed to the outer wall of the fixing ring 311. The mounting block 312 is threadedly connected to the outer wall of the roller body 1 by a locking bolt 313. By rotating the locking bolt 313, the mounting block 312 can be removed from the roller body 1 and the mounting block 312. Workers can then remove the mounting plate 219 and clean the several sets of second holes 315 on the surface of the second connecting plate 314 to ensure that the second holes 315 do not become clogged, thereby improving the suction effect inside the roller body 1.

[0034] Working principle: When needed, the adjusting motor 223 is turned on to drive the rotating rod 224 and the rotating gear 225 to rotate. The rotating gear 225 drives the rack plate 221 to move inside the fixed plate 212. The rack plate 221 pushes the movable plate 213 to move towards the middle position of the first hole 211. The movable plate 213 drives the sealing layer 214 to move and pushes the linerboard to the center position of the roller body 1, ensuring that the linerboard will not shift during transportation and thus ensuring that the linerboard can be processed better.

[0035] Then, the drive motor 216 is turned on to drive the roller 1 to rotate, so as to convey the boxboard paper. The movable block 226 can be slidably connected to the machine tool through the sliding groove 227 to achieve the purpose of further horizontal transportation. The vacuum pump 217 is turned on, and the vacuum pump 217 can adsorb the outside air and enter the inside of the roller 1 through the first hole 211, and discharge it to the outside through the output pipe 218, so as to adsorb the boxboard paper and stably fall on the outer wall of the roller 1.

[0036] When impurities need to be cleaned, the locking bolt 313 is rotated, and the threaded action causes the locking bolt 313 to disengage from the mounting block 312 and the roller body 1. Then, the mounting plate 219 is pulled to disengage it from the roller body 1. The staff can then clean the blocked second hole 315 to ensure that the suction of the vacuum pump 217 is not affected, so that the linerboard can be adsorbed and moved by the roller body 1.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
