Description

Technical Field

[0001] This utility model relates to the field of paper product surface spraying technology, and more specifically, it relates to a paper product surface anti-compression coating spraying equipment. Background Technology

[0002] A compressive strength coating for paper products is a functional coating applied to the surface of paper or paperboard through a coating process (such as roll coating, spray coating, or dip coating). After drying or curing, it forms a continuous protective film. Its core function is to enhance the compressive strength, abrasion resistance, folding endurance, and surface hardness of paper products through physical film formation or chemical cross-linking. At the same time, it can improve moisture resistance, printability (such as ink adhesion), and appearance (such as gloss). The coating material is usually based on polymer resins (such as acrylates, polyurethanes, and water-based PVA), supplemented with nanofillers (such as calcium carbonate and silica) or functional additives such as wax emulsions to meet the performance requirements of different scenarios. This technology is widely used in corrugated boxes, packaging boxes, labels, book covers, and other fields, aiming to improve the mechanical stability and durability of paper products in stacking, transportation, folding, or friction environments.

[0003] This equipment is an automated or semi-automated device specifically designed for coating paper products with a pressure-resistant functional coating. Through processes such as spraying, roller coating, or dip coating, it uniformly applies pressure-resistant coatings (such as water-based resins, UV-curing materials, or nanocomposite coatings) to the surface of paper or cardboard, and then dries or cures to form a continuous protective film, thereby significantly improving the pressure resistance, abrasion resistance, folding endurance, and surface protection performance of paper products. Its core components include a feeding system, coating modules (such as spray guns, rollers, or doctor blades), drying / curing devices (hot air, UV lamps, or infrared), and a control system. It is widely used in packaging cartons, high-end gift boxes, labels, and other fields to meet the precise requirements for coating thickness, uniformity, and efficiency in industrial production.

[0004] Because paper products may become contaminated with dust, fiber debris, oil, and other impurities during production, transportation, or storage, existing paper product surface pressure coating spraying equipment usually requires cleaning the paper products before spraying. This is a key step to ensure the quality and performance of the coating. However, most paper product surface pressure coating spraying equipment does not have the function of cleaning the cardboard box surface. These contaminants will significantly reduce the adhesion between the coating and the paper surface, resulting in the coating being easy to peel off, blister, or crack.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a pressure-resistant coating spraying device for paper products. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a paper product surface anti-compression coating spraying equipment.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a paper product surface anti-compression coating spraying device, comprising a base, a conveyor belt connected in the base, and a first support frame and a second support frame connected to the upper end of the base, wherein a spray head is connected to the side of the second support frame corresponding to the conveyor belt;

[0008] The conveyor belt is connected to multiple rotating mechanisms for rotating the paper products to be sprayed. Each rotating mechanism is connected to a clamping mechanism for clamping and fixing the paper products to be sprayed.

[0009] A first cleaning mechanism is horizontally connected to one side of the first support frame corresponding to the conveyor belt, which is used to clean the upper end of the paper product to be sprayed. A second cleaning mechanism is vertically symmetrically connected to one side of the first support frame corresponding to the conveyor belt, which is used to vertically clean the paper product to be sprayed.

[0010] Preferably, each of the rotating mechanisms includes a movable platform, a support column, and a first gear. Multiple movable platforms are connected at intervals on the conveyor belt. A support column is rotatably connected to the upper end of each movable platform. A first gear is connected to each support column. A second rack is connected to one side of the base. Each first gear can mesh with the second rack to facilitate the rotation of the paper product.

[0011] Preferably, each of the clamping mechanisms includes a connecting frame, an electric telescopic rod, a clamping plate, and a protective pad. A connecting frame is connected to the upper end of each of the support columns. An electric telescopic rod is symmetrically connected to each of the connecting frames. A clamping plate is connected to the telescopic end of each of the electric telescopic rods. A protective pad is connected to each of the clamping plates to facilitate the clamping and fixing of paper products.

[0012] Preferably, the first cleaning mechanism includes a first roller brush and two second gears. The first support frame is laterally rotatably connected to the first roller brush on one side of the conveyor belt. The two ends of the first roller brush are respectively connected to the second gears. A first rack is connected to the conveyor belt. The first rack meshes with one of the second gears to facilitate cleaning the top of the paper product.

[0013] Preferably, each of the second cleaning mechanisms includes a second roller brush and a third gear. The first support frame is vertically and symmetrically connected to the second roller brush on one side of the conveyor belt. Each of the two second roller brushes is connected to a third gear, and each third gear meshes with the two second gears to facilitate vertical cleaning of paper products.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, through the first cleaning mechanism and the second cleaning mechanism set on the first support frame, when the conveyor belt rotates, the connected first rack will move. When the first rack rotates, the meshing second gear will rotate. When the second gear rotates, the connected first roller brush will rotate in the first support frame. When the first roller brush rotates, the two connected first gears will rotate. When the two first gears rotate, the two meshing second gears will rotate. When the two second gears rotate, the connected second roller brush will rotate. When the rotating paper product enters the cleaning area composed of one horizontal roller brush and two vertical roller brushes, the rotating first roller brush and the two rotating second roller brushes will clean the rotating paper product, thereby solving the problem in the background technology that contaminants will significantly reduce the adhesion between the coating and the paper surface, resulting in easy peeling, blistering or cracking of the coating.

[0016] 2. In this utility model, through multiple rotating mechanisms set on the conveyor belt and a second rack on the base, when the conveyor belt is started, it will move each connected moving platform. When each moving platform moves in sequence, it will cause the connected support column to move together. When the support column moves, it will cause the connected first gear to move. At this time, each first gear that moves with the conveyor belt will roll on the meshing second rack. At this time, each first gear will rotate. When the first gear rotates, it will cause the connected support column to rotate. When each support column rotates, it will cause the connected clamping mechanism to rotate. When each clamping mechanism rotates, it will cause the clamped paper product to rotate. The centrifugal force generated by the rotation can effectively accelerate the removal of dust and debris adhering to the paper surface. At the same time, the paper product continues to rotate in the clamping mechanism, so that the cleaning tool can cover the edges, corners and double-sided areas that are difficult to reach in the stationary state, avoiding the dead corner problem of traditional one-way cleaning.

[0023] like Figure 1-4 As shown, this utility model provides a paper product surface anti-compression coating spraying equipment, including a base 1, which is used to ensure the stability of the conveyor belt 2. The conveyor belt 2 is connected in the base 1 for transportation. A first support frame 3 and a second support frame 4 are connected to the upper end of the base 1. A spray head 10 is connected to one side of the second support frame corresponding to the conveyor belt 2 for spraying the paper product.

[0024] The conveyor belt 2 is equipped with multiple rotating mechanisms 5 for rotating the paper products to be coated. Each rotating mechanism 5 is connected to a clamping mechanism 6 for clamping and fixing the paper products to be coated. When the conveyor belt 2 is started, it will move each connected movable platform 501. As each movable platform 501 moves sequentially, the connected support column 502 will move along with it. When the support column 502 moves, the connected first gear 503 will move. At this time, each first gear 503 that moves with the conveyor belt 2 will roll on the meshing second rack 11. When the first gear 503 rotates, the connected support column 502 will rotate. When each support column 502 rotates, the connected clamping mechanism 6 will rotate. When each clamping mechanism 6 rotates, the clamped paper product will rotate. The centrifugal force generated by the rotation can effectively accelerate the removal of dust and debris from the paper surface. At the same time, the paper product continues to rotate in the clamping mechanism 6, allowing the cleaning tool to cover edges, corners and double-sided areas that are difficult to reach when stationary, avoiding the dead corner problem of traditional one-way cleaning.

[0025] Each rotating mechanism 5 includes a moving platform 501, a support column 502, and a first gear 503. Multiple moving platforms 501 are connected at intervals on the conveyor belt 2 to drive the support column 502. Each moving platform 501 is rotatably connected to the support column 502 at its upper end to drive the connecting frame 601. Each support column 502 is connected to a first gear 503, which causes the connected support column 502 to rotate when the first gear 503 rotates. A second rack 11 is connected to one side of the base 1 to enable the rotation of each first gear 503, thereby enabling the first roller brush 701 to rotate and clean the paper products. Each first gear 503 can mesh with the second rack 11.

[0026] Each clamping mechanism 6 includes a connecting frame 601, an electric telescopic rod 602, a clamping plate 603, and a protective pad 604. Each support column 502 is connected to a connecting frame 601 at its upper end, which is used to place paper products. Each connecting frame 601 is symmetrically connected to an electric telescopic rod 602, which is used to control the lateral movement of each clamping plate 603. Each telescopic end of the electric telescopic rod 602 is connected to a clamping plate 603, which is used to clamp and fix the paper products. Each clamping plate 603 is connected to a protective pad 604, which is used to protect the paper products.

[0027] A first cleaning mechanism 7 is horizontally connected to one side of the first support frame 3 corresponding to the conveyor belt 2, used to clean the upper end of the paper product to be sprayed. A second cleaning mechanism 8 is vertically symmetrically connected to one side of the first support frame 3 corresponding to the conveyor belt 2, used to vertically clean the paper product to be sprayed. This mechanism ensures that when the conveyor belt 2 rotates, the connected first rack 9 moves; when the first rack 9 rotates, the meshing second gear 702 rotates; and when the second gear 702 rotates, the connected first roller brush 701 rotates within the first support frame 3. When the roller brush 701 rotates, it will cause the two connected first gears 503 to rotate. When the two first gears 503 rotate, they will cause the two meshing second gears 702 to rotate. When the two second gears 702 rotate, they will cause the connected second roller brush 801 to rotate. When the rotating paper product enters the cleaning area consisting of one horizontal roller brush and two vertical roller brushes, the rotating first roller brush 701 and the two rotating second roller brushes 801 will clean the rotating paper product, effectively cleaning the paper product from all directions before spraying.

[0028] The first cleaning mechanism 7 includes a first roller brush 701 and two second gears 702. The first support frame 3 is laterally rotatably connected to the first roller brush 701 on the side corresponding to the conveyor belt 2, which is used to clean the top of the paper product. The two ends of the first roller brush 701 are respectively connected to the second gears 702, which are used to rotate the first roller brush 701. The conveyor belt 2 is connected to a first rack 9, which is used to control the rotation of one of the second gears 702. The first rack 9 and one of the second gears 702 mesh with each other.

[0029] Each second cleaning mechanism 8 includes a second roller brush 801 and a third gear 802. The first support frame 3 is vertically and symmetrically connected to the second roller brush 801 on the side corresponding to the conveyor belt 2. It is used to perform vertical cleaning of the paper products to be sprayed. Each of the two second roller brushes 801 is connected to a third gear 802, which is used to control the rotation of each second roller brush 801, thereby cleaning the paper products by rotating each second roller brush 801. Each third gear 802 meshes with the two second gears 702 respectively.

[0030] Working principle: When it is necessary to clean the paper products to be sprayed, first place the paper products in the connecting frame 601, and then simultaneously start the two electric extension rods on the connecting frame 601. When the two electric extension rods 602 are started, the connected clamping plates 603 will move laterally until the paper products are clamped and fixed. At the same time, the protective pads 604 on the two clamping plates 603 will protect the clamped paper products and prevent slipping.

[0031] Next, the conveyor belt 2 is started. When the conveyor belt 2 is started, it will move each connected moving platform 501. When each moving platform 501 moves in sequence, the connected support column 502 will move together. When the support column 502 moves, the connected first gear 503 will move. At this time, each first gear 503 that moves with the conveyor belt 2 will roll on the meshing second rack 11. At this time, each first gear 503 will rotate. When the first gear 503 rotates, the connected support column 502 will rotate. When each support column 502 rotates, the connected clamping mechanism 6 will rotate. When each clamping mechanism 6 rotates, the clamped paper product will rotate.

[0032] Simultaneously, when the conveyor belt 2 rotates, it will cause the connected first rack 9 to move. When the first rack 9 rotates, it will cause the meshing second gear 702 to rotate. When the second gear 702 rotates, it will cause the connected first roller brush 701 to rotate within the first support frame 3. When the first roller brush 701 rotates, it will cause the two connected first gears 503 to rotate. When the two first gears 503 rotate, they will cause the two meshing second gears 702 to rotate. When the two second gears 702 rotate, they will cause the connected second roller brush 801 to rotate. When the rotating paper product enters the cleaning area composed of one horizontal roller brush and two vertical roller brushes, the rotating first roller brush 701 and the two rotating second roller brushes 801 will clean the rotating paper product.

[0033] After the paper products are cleaned, they will follow the conveyor belt 2 into the lower end of the second support frame 4, and at the same time the spray head 10 will be activated to spray the paper products.

Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
