Description

Technical Field

[0001] This utility model relates to the field of pulp board technology, specifically to an automatic pulp board slitting machine. Background Technology

[0002] Pulp board is a sheet material made of plant fibers. It has excellent moisture resistance, fire resistance, sound insulation and heat insulation properties, and high strength and stability. Its main component is plant fiber, which can reduce its impact on the environment and makes it more environmentally friendly. It is commonly divided into hard pulp board and soft pulp board, and is widely used in many fields such as papermaking, packaging, building decoration, and furniture manufacturing.

[0003] The production process of pulp board involves separating the fibers of wood or other plant materials (such as bagasse) through a pulping machine, then removing impurities through processes such as cooking, washing, screening, and bleaching, followed by the addition of environmentally friendly adhesives or resins for bonding, and finally pressing and dehydrating under high temperature and pressure to form a board material with a certain thickness and strength.

[0004] After pressing and before being made into finished products, pulp boards need to undergo slitting and drying processes to form finished products of standard sizes for easy transportation and storage. During the slitting process in pulp board production, the pulp board still has a high moisture content. If slitting is done directly with a slitting blade, the beveled edge and thickness of the blade will cause a slight localized bulge on the top side of the pulp board corresponding to the slitting blade. If not properly handled, this bulge will be more susceptible to additional impacts and friction during subsequent drying, packaging, and transportation, leading to localized damage and chipping, affecting the product's appearance and quality. This requires improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic pulp board slitting machine to solve the problem that pulp board slitting easily produces bulges, leading to localized damage and chipping of the product.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An automatic pulp board slitting machine includes a horizontal conveyor for conveying pulp boards, and a slitting assembly, a coating assembly, and a leveling assembly are respectively arranged above the pulp boards along the conveying direction of the pulp boards.

[0008] The slitting assembly includes a slitting push rod, a blade holder fixed to the lower end of the piston rod of the slitting push rod, and a slitting blade fixed below the blade holder. The slitting blade is a single-edged blade, and the bevel of the slitting blade's blade edge corresponds to the downstream side of the pulp board conveying.

[0009] The coating assembly includes an unwinding roller for winding the film and a take-up roller for winding the edge material. The wound film is provided with intermittently spaced anti-sticking film. The unwinding roller and the take-up roller are driven by an unwinding motor and a take-up motor, respectively. A pressure push rod is provided directly above the film between the unwinding roller and the take-up roller. The lower end of the piston rod of the pressure push rod is fixed with an insert plate through a connecting seat. The insert plate is provided with a slope near the bottom on the side downstream of the pulp board conveyor.

[0010] The leveling assembly includes a pressure roller that is in contact with and tumbledly connected to the upper surface of the pulp board.

[0011] Preferably, the slitting assembly further includes slots on both sides of the slitting blade, with absorbent cotton in contact with both sides of the slitting blade installed in each of the two slots, and a water supply tube connected to the top of the slots.

[0012] Preferably, the slitting assembly further includes a regulating valve installed on the water supply capillary.

[0013] Preferably, both the cutting push rod and the pressing push rod are servo push rods.

[0014] Preferably, the unwinding motor and the winding motor are a servo motor and a torque motor, respectively.

[0015] Preferably, the bottom of the insert plate has a smooth rounded corner structure, and the sloping surface on one side of the insert plate is parallel to the slitting surface of the cutting blade.

[0016] Preferably, the pressure roller is a smooth stainless steel non-powered circular roller.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention involves pressing a separating anti-sticking film into the slit portion of the pulp board after slitting, and then using a pressure roller to roll the pulp board from the top to restore the raised areas created by slitting to a flat state. The separating anti-sticking film prevents adjacent pulp boards from sticking together again after restoring their flatness, facilitating the separation of the slit pulp boards for drying. This achieves the effect of ensuring a flat product surface and avoids the problem of pulp board bulges being prone to collisions and friction. It also solves the problem of pulp board bulges easily causing localized damage and chipping of the product. Attached Figure Description

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: an automatic pulp board slitting machine, including a horizontal conveyor 2 for conveying pulp board 1, and a slitting component 3, a coating component 4 and a leveling component 5 respectively arranged above the pulp board 1 along the conveying direction of the pulp board 1;

[0026] The slitting assembly 3 includes a slitting push rod 31, a blade holder 32 fixed to the lower end of the piston rod of the slitting push rod 31, and a slitting blade 33 fixed below the blade holder 32. The slitting blade 33 is a single-edged blade, and the bevel of the blade edge of the slitting blade 33 corresponds to the downstream side of the pulp board 1.

[0027] The slitting assembly 3 also includes slots 34 on both sides of the slitting blade 33. Water-absorbing cotton 35 that contacts both sides of the slitting blade 33 is installed in the two slots 34 respectively. A water supply tube 36 is connected to the top of the slots 34. The slitting assembly 3 also includes a regulating valve 37 installed on the water supply tube 36.

[0028] The coating assembly 4 includes an unwinding roller 41 for winding the film 6 and a take-up roller 42 for winding up the edge material 62. The film 6 is provided with intermittently spaced anti-sticking film 61. The unwinding roller 41 and the take-up roller 42 are driven by an unwinding motor 43 and a take-up motor 44, respectively. A pressing push rod 45 is provided directly above the film 6 at a position between the unwinding roller 41 and the take-up roller 42. The lower end of the piston rod of the pressing push rod 45 is fixed with an insert plate 47 through a connecting seat 46.

[0029] The insert plate 47 is provided with a sloping surface near the bottom on the downstream side of the pulp board 1. The slitting push rod 31 and the pressing push rod 45 are both servo push rods. The unwinding motor 43 and the winding motor 44 are servo motors and torque motors, respectively. The bottom of the insert plate 47 has a smooth rounded corner structure, and the sloping surface on one side of the insert plate 47 is parallel to the blade slope of the slitting blade 33.

[0030] The leveling assembly 5 includes a pressure roller 51 that is in contact with and rolledly connected to the upper surface of the pulp board 1. The pressure roller 51 is a smooth stainless steel non-powered round roller.

[0031] Working principle:

[0032] Pulp board 1 is conveyed to the right by horizontal conveyor 2. The slitting pusher 31 drives the slitting knife 33 to reciprocate vertically via the knife holder 32, slitting the pulp board 1 to a fixed length. Each two slits form one pulp board 1. The pressing pusher 45 is positioned at a distance of one pulp board 1 product length from the slitting pusher 31. The unwinding motor 43 and the winding motor 44 drive the unwinding roller 41 and the winding roller 42 to rotate. The pressing pusher 45 drives the insert plate 47 to reciprocate vertically via the connecting seat 46. The insert plate 47 presses down on the separating anti-stick film 61 on the film 6 to separate it and insert it between two adjacent pulp boards 1. The pulp board 1 drives the separating anti-stick film 61 to continue to be conveyed. The separating anti-stick film 61 inserted between two adjacent pulp boards 1 drives the unwinding roller 41 to rotate. The separated anti-stick film 61 moved by the inserted plate 47 by the length of one pulp board 1 and covered the surface of one pulp board 1. When it passed the pressure roller 51, it was rolled by the pressure roller 51 in contact with the upper surface of the pulp board 1, so that the raised parts were restored to flatness. When the next pulp board 1 moves under the insert plate 47, the pressing push rod 45 drives the insert plate 47 to reciprocate in the vertical direction through the connecting seat 46. The insert plate 47 presses down on the separating anti-stick film 61 on the film 6, which has moved by the length of one pulp board 1, to separate it from the separating anti-stick film 61 that was previously covered on the previous pulp board 1, and inserts it between two adjacent pulp boards 1. Following the above cyclic steps, after multiple slitting of the pulp board 1 and the separating anti-sticking film 61, and rolling by the pressure roller 51, the separating anti-sticking film 61 is covered and smoothed on the upper surface of the pulp board 1.
