Description

Technical Field

[0001] This utility model relates to the field of paper slitting machine technology, specifically a pressing device for a paper slitting machine. Background Technology

[0002] Paper slitting machines are specialized equipment used in the paper processing industry. Their core function is to precisely cut and divide large-format paper and cardboard into smaller finished products according to preset dimensions. They are widely used in printing plants, packaging plants, and carton factories, and are key equipment for improving paper cutting efficiency and dimensional accuracy.

[0003] The paper slitting machine works by conveying large-format paper or cardboard into the equipment; then the conveying mechanism drives the paper forward, followed by the cutting mechanism, which cuts the paper into preset sizes; finally, the cut small-format paper is conveyed to the collection area by the discharge mechanism.

[0004] When existing paperboard enters the paper slitting machine, it is subjected to traction for a long time, which causes the paperboard to deviate during the conveying process, resulting in the cut paperboard not conforming to the expected value. Therefore, a pressing device for paper slitting machine is proposed to address the above problem. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A pressing device for a paper slitting machine, comprising a worktable; a pair of first rollers are rotatably connected to the inner side wall of the worktable; multiple sets of cutters are arranged in the middle of the first rollers; the cutters are evenly distributed at the top of the first rollers; a pair of linear motors are fixedly connected to the side wall of the worktable; a second roller is fixedly connected to the middle of the linear motors; a slide rail is fixedly connected to the top of the worktable; a sliding seat is slidably connected to the top of the slide rail; bolts are threadedly connected to the side wall of the sliding seat; a first support rod is rotatably connected to the top of the sliding seat; the second rollers can be driven by the linear motors to adjust the spacing, accurately matching the squeezing force for paperboards of different thicknesses, ensuring that the paperboard fits the conveying surface, reducing the warping of the paperboard during conveying, laying the foundation for subsequent cutting; in conjunction with the adjustable spacing of the sliding seat, the first support rod limits the width of the paperboard to a specified range, which can reduce the deviation of the paperboard during conveying, resulting in dimensional deviation after the paperboard is cut by the cutter, causing the paperboard to be scrapped, and improving the positioning accuracy of the paperboard during feeding.

[0007] Preferably, a first fixing rod is fixedly connected to the top of the workbench; the first fixing rod is located on one side of the bolt; a fixing seat is fixedly connected to the top of the first fixing rod; a rotating shaft is rotatably connected to the top of the fixing seat; the fixing seat can provide upward support for the uncut cardboard portion, keeping the cardboard in a horizontal conveying state, reducing cardboard sagging and deformation damage, and cooperating with the rotating shaft to increase the stability of cardboard feeding.

[0008] Preferably, a pair of grooves are provided on the side wall of the first roller shaft; a support seat is fixedly connected to the side wall of the cutter; a second fixing rod is fixedly connected to the top of the support seat; by disassembling and installing the second fixing rod, the spacing between multiple sets of cutters can be adjusted, so that the first roller shaft can be used to cut cardboard of different widths, reducing the need to disassemble the first roller shaft as a whole when changing different cutting sizes, which leads to cumbersome replacement.

[0009] Preferably, a pair of guide discs are fixed to the side wall of the first support rod; the guide discs are located in the middle section of the first support rod; the pair of guide discs in the middle section of the first support rod can further limit the cardboard from both sides, so that the cardboard is centered and constrained on the conveying path, ensuring that the cardboard is accurately positioned when it enters the first roller, and improving the dimensional accuracy after cutting.

[0010] Preferably, a pair of second support rods are fixedly connected to the inner side wall of the workbench; the second support rods are located on the side of the first roller shaft; a wiping block is fixedly connected to the bottom end of the second support rod; the wiping block is slidably connected to the cutter; by the wiping block sliding contacting the cutter, contaminants are scraped off in real time, ensuring that the cutter is always kept clean and reducing defects such as increased burrs on the cardboard after cutting caused by contaminant adhesion.

[0011] Preferably, a silicone layer is fixed to the side wall of the second roller shaft; the silicone layer wraps around the second roller shaft; the silicone layer can increase the friction between the second roller shaft and the paperboard, enhance the squeezing force of the second roller shaft on the paperboard, and make the paperboard maintain a uniform speed during conveying.

[0012] The advantages of this utility model are: 1. The pressing device for a paper slitting machine described in this utility model can drive the second roller shaft to adjust the spacing via a linear motor, precisely matching the squeezing force for paperboards of different thicknesses, ensuring that the paperboard adheres to the conveying surface, reducing warping during the conveying process, and laying the foundation for subsequent cutting. In conjunction with the sliding seat adjusting the spacing, the first support rod limits the width of the paperboard within a specified range, which can reduce the deviation of the paperboard during conveying, resulting in dimensional deviations after the paperboard is cut by the cutter, causing the paperboard to be scrapped, and improving the positioning accuracy of the paperboard during feeding.

[0013] 2. The pressing device for a paper slitting machine described in this utility model can provide upward support for the uncut cardboard portion through a fixed base, keeping the cardboard in a horizontal conveying state, reducing deformation and breakage caused by sagging, and increasing the stability of cardboard feeding when it is rotated with the rotating shaft.

[0017] 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 scope of protection of the present utility model.

[0018] Specific implementation examples are given below.

[0019] like Figures 1 to 5As shown in the embodiment of this utility model, a pressing device for a paper slitting machine includes a worktable 1; a pair of first rollers 11 are rotatably connected to the inner side wall of the worktable 1; multiple sets of cutters 12 are arranged in the middle of the first rollers 11; the cutters 12 are evenly distributed at the top of the first rollers 11; a pair of linear motors 13 are fixedly connected to the side wall of the worktable 1; a second roller 14 is fixedly connected to the middle of the linear motors 13; a slide rail 15 is fixedly connected to the top of the worktable 1; a sliding seat 16 is slidably connected to the top of the slide rail 15; bolts 17 are threadedly connected to the side wall of the sliding seat 16; a first support rod 18 is rotatably connected to the top of the sliding seat 16; during operation, the cardboard to be cut is passed between the pair of second rollers 14, and then the pair of second rollers 14 are driven to rotate, the second rollers 14 can squeeze the cardboard, so that the cardboard is smoothly conveyed to the pair of first rollers 11, and the multiple sets of cutters 12 in the middle of the first rollers 11 can cut the cardboard. When dealing with cardboard of different thicknesses, a pair of linear motors 13 can be activated to adjust the spacing between a pair of second rollers 14 according to the thickness of the cardboard. Before the cardboard is traction and conveyed, a pushing force can be applied to the sliding seat 16 to slide in the middle of the slide rail 15. The spacing between the pair of sliding seats 16 can be adjusted according to the width of the cardboard. Then, the bolts 17 are rotated to fix the sliding seat 16. When the cardboard is conveyed, the first support rod 18 will rotate and contact the side wall of the cardboard, so that the cardboard is limited during conveying. The spacing can be adjusted by driving the second rollers 14 through the linear motors 13 to accurately match the squeezing force for cardboard of different thicknesses, ensuring that the cardboard fits the conveying surface and reducing the warping of the cardboard during conveying, laying the foundation for subsequent cutting. In conjunction with the adjustment of the spacing of the sliding seats 16, the first support rod 18 limits the width of the cardboard to a specified range, which can reduce the deviation of the cardboard during conveying, which would cause the cardboard to be cut by the cutter 12 and become scrapped, thus improving the positioning accuracy of the cardboard during feeding.

[0020] like Figure 1 and Figure 5 As shown, a first fixing rod 2 is fixedly connected to the top of the workbench 1; the first fixing rod 2 is located on one side of the bolt 17; a fixing seat 21 is fixedly connected to the top of the first fixing rod 2; a rotating shaft 22 is rotatably connected to the top of the fixing seat 21; during operation, when the cardboard is squeezed and conveyed by the second roller shaft 14, the fixing seat 21 can support the cardboard, so that the uncut part of the cardboard will not sag due to its weight, and the rotating shaft 22 will contact and rotate with the bottom of the cardboard; the fixing seat 21 can form an upward support for the uncut part of the cardboard, keeping the cardboard in a horizontal conveying state, reducing the deformation and breakage caused by the sagging of the cardboard, and increasing the stability of the cardboard feeding when rotating with the rotating shaft 22.

[0021] like Figures 2 to 3As shown, a pair of grooves 3 are provided on the side wall of the first roller shaft 11; a support base 31 is fixedly connected to the side wall of the cutter 12; a second fixing rod 32 is fixedly connected to the top of the support base 31; during operation, when it is necessary to cut cardboard of different widths, the second fixing rod 32 can be removed from the top of the support base 31, and then a pushing force can be applied to the cutter 12, which can slide on the top of the groove 3. After adjusting the spacing between multiple sets of cutters 12, the second fixing rod 32 can be installed back into the middle of the support base 31 to fix the cutter 12; by removing and installing the second fixing rod 32, the spacing between multiple sets of cutters 12 can be adjusted, so that the first roller shaft 11 can be used to cut cardboard of different widths, reducing the need to disassemble the first roller shaft 11 as a whole when changing different cutting sizes, which leads to cumbersome replacement.

[0022] like Figure 4 As shown, a pair of guide discs 4 are fixed to the side wall of the first support rod 18; the guide discs 4 are located in the middle section of the first support rod 18; during operation, when the first support rod 18 rotates in contact with the cardboard, the pair of guide discs 4 in the middle of the first support rod 18 can restrict the cardboard in the middle, so that the cardboard is further restricted when moving; the pair of guide discs 4 in the middle section of the first support rod 18 can further limit the cardboard from both sides, so that the cardboard is centered and constrained on the conveying path, ensuring that the cardboard is accurately positioned when entering the first roller 11, and improving the dimensional accuracy after cutting.

[0023] like Figure 2 As shown, a pair of second support rods 5 are fixedly connected to the inner wall of the workbench 1; the second support rods 5 are located on the side of the first roller shaft 11; a wiping block 51 is fixedly connected to the bottom end of the second support rods 5; the wiping block 51 is slidably connected to the cutter 12; during operation, contaminants will appear on the surface of the cutter 12 after long-term use. When the cutter 12 cuts the cardboard, the contaminants will come into contact with the cardboard. At this time, the wiping block 51 can continuously clean the cardboard while the cutter 12 is rotating; by sliding contacting the wiping block 51 with the cutter 12, the contaminants are scraped off in real time, ensuring that the cutter 12 is always kept clean and reducing the defects such as increased burrs on the cardboard after the cutter 12 is cut due to the adhesion of contaminants.

[0024] like Figure 4 As shown, a silicone layer 6 is fixed to the side wall of the second roller shaft 14; the silicone layer 6 wraps around the second roller shaft 14; during operation, when the second roller shaft 14 presses the cardboard, the silicone layer 6 can contact the cardboard, thereby increasing the friction between the second roller shaft 14 and the cardboard; the silicone layer 6 can increase the friction between the second roller shaft 14 and the cardboard, enhance the squeezing force of the second roller shaft 14 on the cardboard, and make the cardboard maintain a uniform speed during conveying.

[0025] Working principle: The cardboard to be cut passes between a pair of second rollers 14, which then rotate, squeezing the cardboard and smoothly conveying it to a pair of first rollers 11. Multiple cutters 12 in the middle of the first rollers 11 cut the cardboard. For cardboard of different thicknesses, a pair of linear motors 13 are activated to adjust the distance between the second rollers 14 according to the cardboard thickness. Before the cardboard is conveyed, a pushing force is applied to the sliding seat 16, which slides along the middle of the slide rail 15. The distance between the sliding seats 16 is adjusted according to the width of the cardboard, and then the bolts 17 are rotated to fix the sliding seats 16. During cardboard conveying, the first support rod 18 rotates and contacts the side wall of the cardboard, creating a limit during conveying. When the cardboard is squeezed and conveyed by the second rollers 14, the fixed seat 21 supports the cardboard, preventing it from being cut. Parts will not sag due to weight, and the rotating shaft 22 will rotate in contact with the bottom of the cardboard. When cutting cardboard of different widths, the second fixing rod 32 can be removed from the top of the support base 31, and then a pushing force can be applied to the cutter 12. The cutter 12 can slide on the top of the groove 3. After adjusting the spacing between multiple sets of cutters 12, the second fixing rod 32 can be installed back into the middle of the support base 31 to fix the cutter 12. When the first support rod 18 rotates in contact with the cardboard, a pair of guide discs 4 in the middle of the first support rod 18 can restrict the cardboard in the middle, further restricting the movement of the cardboard. After long-term use, contaminants will appear on the surface of the cutter 12. When the cutter 12 cuts the cardboard, the contaminants will come into contact with the cardboard. At this time, the wiping block 51 can continuously clean it while the cutter 12 is rotating. When the second roller shaft 14 presses the cardboard, the silicone layer 6 can come into contact with the cardboard, increasing the friction between the second roller shaft 14 and the cardboard.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
