Description

Technical Field

[0001] The invention relates to the field of cutting technology, and in particular to a paper rough edge cutting device for notebook production. Background Art

[0002] The cutting process in notebook production is a key link in the manufacturing process, mainly used to cut large-size paper or materials into pages of standard specifications. Traditional cutting pursues smooth and flat edges to meet daily use and aesthetic requirements. To achieve this goal, removing burrs is an indispensable step. In traditional processes, burr removal is mainly completed by high-precision cutting machines, using sharp blades or rotary cutters to cut the edges of the paper in one go to ensure that the edges are neat and burr-free. In modern production, laser cutting technology is also widely used to remove burrs. The high energy of the laser beam instantly vaporizes the excess fibers on the edge of the paper to achieve precise and smooth cutting effects, while avoiding the debris problem that may be generated by mechanical cutting. In addition, grinding or polishing equipment is often used in the post-process to perform secondary processing on the edges to further improve the smoothness and durability of the edges. In the prior art, when cutting a whole stack of paper, the paper is often not aligned, which will cause paper waste, aligning the paper is time-consuming and labor-intensive, and will also reduce efficiency. Summary of the invention

[0003] In view of the above technical problems, the present invention discloses a rough edge cutting device for paper production for notebook production, including a cutting table and a mounting plate, a vibrator 1 is installed on the mounting plate, a cutting assembly is arranged on the cutting table, a third connecting rod is rotatably installed on the mounting plate, a paperboard is installed on the third connecting rod, the paperboard is a rectangular plate, two adjacent edges of which are fixedly installed with a first alignment plate and a second alignment plate, the two edges of the paper are aligned with the first alignment plate and the second alignment plate, a vibrator 2 is installed on the mounting plate, and the paperboard is in contact with the vibrator 2 for vibration alignment. Through the above technical scheme, the vibrator 2 is used to vibrate before the paper is cut, so that the paper in the paperboard can be attached to the edges of the first alignment plate and the second alignment plate, and then the other two edges are cut. Such a technical scheme greatly improves the cutting efficiency, and can ensure the overall neatness when only two edges are cut, and one of the uncut edges is packaged, and the other three edges are cut and trimmed.

[0004] Furthermore, an adjustment rod is fixedly mounted on the third connecting rod, and a plurality of through holes are arranged on the adjustment rod and the third connecting rod, and the length is adjusted in series through different through holes. A rotating shaft is rotatably mounted on the adjustment rod, and the rotating shaft is fixedly connected to the paper board, and a torsion spring is fixedly mounted between the rotating shaft and the adjustment rod.

[0005] Furthermore, a fixing plate is slidably mounted on the paperboard, and the fixing plate and the paperboard clamp the paper. Through the above technical solution, the paper is clamped by the fixing plate, and the fixing plate is loosened during vibration alignment, and the fixing plate is clamped after alignment, ensuring that the paper will not be scattered again during the process of moving to the cutting assembly.

[0006] Furthermore, the first alignment plate and the second alignment plate are both fixedly mounted with a fixed electric cylinder, the fixed plate is fixedly mounted with a matching plate, an inclined groove is arranged on the matching plate, a matching shaft is fixedly mounted on the cylinder arm of the fixed electric cylinder, and the matching shaft cooperates with the inclined groove to control the sliding of the fixed plate.

Through the above technical solution, since the distance between the third connecting rod and the adjusting rod is adjustable, the position of the paperboard placed on the cutting table is different, and the cooperation between the movable plate and the rotating shaft can ensure that the position of the cutting assembly is always relatively fixed with the position of the paper, thereby ensuring the accuracy of the cutting position.

[0008] Furthermore, a sliding shaft is fixedly mounted on the positioning plate, a side support plate is fixedly mounted on the cutting table, the side support plate is slidably connected to the sliding shaft, and a return spring is fixedly mounted between the sliding shaft and the side support plate.

[0009] Furthermore, the positioning plate is fixedly provided with a mounting column, the mounting column is fixedly provided with a vertical electric cylinder, the cylinder arm of the vertical electric cylinder drives a horizontal electric cylinder, the cylinder arm of the horizontal electric cylinder is fixedly provided with a cutting knife, a squeezing plate is slidably provided on the cutting knife, a squeezing spring is fixedly provided between the squeezing plate and the cutting knife, and the cutting knife cuts after the squeezing plate presses the paper. Through the above technical scheme, the horizontal electric cylinder can control the cutting position of the cutting knife, when the cutting knife is close to the fixed plate for cutting, the squeezing plate contacts the fixed plate, and when the cutting knife cuts the position outside the fixed plate, the squeezing plate presses the extended paper for cutting, ensuring that the paper will not swing during cutting, resulting in inaccurate cutting.

[0010] Furthermore, the mounting plate is provided with two upper and lower mounting holes, the mounting plate is fixedly mounted with a driving motor, a first connecting rod is fixedly mounted on the rotating shaft of the driving motor, a second connecting rod is hinged on the first connecting rod, and a third connecting rod is hinged on the second connecting rod.

Through the above technical solution, the vibration frequency and amplitude of the vibrator 1 and the vibrator 2 are different, and grounding through the grounding metal plate can reduce static electricity between the papers, making it easier to align the papers.

[0012] The beneficial effects of the present invention compared with the prior art are: (1) Through the technical solution of the present invention, the vibrator 2 is used to vibrate before the paper is cut, so that the paper in the paperboard can be attached to the edges of the first alignment plate and the second alignment plate, and then the other two edges are cut. This technical solution greatly improves the cutting efficiency and can ensure that the overall neatness is achieved when only two edges are cut, one of the uncut edges is packaged, and the other three edges are cut and trimmed.

[0013] (2) According to the technical solution of the present invention, the paper is clamped by a fixing plate, which is loosened during vibration alignment and clamped after alignment, thereby ensuring that the paper will not be scattered again during the process of moving to the cutting assembly.

[0014] (3) According to the technical solution of the present invention, since the distance between the third connecting rod and the adjusting rod is adjustable, the position of the paperboard placed on the cutting table is different.

When the cutting knife is close to the fixed plate for cutting, the squeezing plate contacts the fixed plate. When the cutting knife cuts the outer side of the fixed plate, the squeezing plate presses the extended paper to cut, thereby ensuring that the paper will not swing during cutting, resulting in inaccurate cutting.

[0016] (5) Through the technical solution of the present invention, the vibration frequency and amplitude of the vibrator 1 and the vibrator 2 are different, and the grounding through the grounding metal plate can reduce the static electricity between the papers, making it easier to align the papers.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 The device for cutting rough edges of paper for notebook production shown in the figure comprises a cutting table 2 and a mounting plate 16, a vibrator 1 24 is mounted on the mounting plate 16, a cutting assembly is mounted on the cutting table 2, a third connecting rod 21 is rotatably mounted on the mounting plate 16, a paperboard 26 is mounted on the third connecting rod 21, the paperboard 26 is a rectangular plate, two adjacent edges of which are fixedly mounted with a first alignment plate 37 and a second alignment plate 38, the two edges of the paper are aligned by affixing the first alignment plate 37 and the second alignment plate 38, a vibrator 2 25 is mounted on the mounting plate 16, and the paperboard 26 is aligned by contacting with the vibrator 2 25. Through the above technical solution, the vibrator 2 25 is used to vibrate before the paper is cut, so that the paper in the paperboard 26 can be attached to the edges of the first alignment plate 37 and the second alignment plate 38, and then the other two edges are cut. Such a technical solution greatly improves the cutting efficiency, and can ensure that the whole is neat when only two edges are cut, one of the uncut edges is packaged, and the other three edges are cut and trimmed.

[0025] In this embodiment, the third connecting rod 21 is fixedly mounted with an adjusting rod 20, and multiple through holes are provided on the adjusting rod 20 and the third connecting rod 21, and the length is adjusted in series through different through holes, and the mounting plate 16 is provided with two upper and lower mounting holes, and the mounting plate 16 is fixedly mounted with a driving motor 17, and the first connecting rod 18 is fixedly mounted on the rotating shaft of the driving motor 17, and the second connecting rod 19 is hinged on the first connecting rod 18, and the third connecting rod 21 is hinged on the second connecting rod 19. A parallelogram connecting rod structure is formed between the first connecting rod 18, the second connecting rod 19, the third connecting rod 21 and the mounting plate 16, and when the third connecting rod 21 is mounted to the mounting hole close to the lower side, the second connecting rod 19 uses a shorter rod, and the distance between the third connecting rod 21 and the adjusting rod 20 is adjusted to a long distance.

[0026] In this embodiment, a circular hinge hole is fixedly installed at the end of the adjustment rod 20, and a rotating shaft 27 is rotatably installed on the circular hinge hole. The rotating shaft 27 is fixedly connected to the paperboard 26, and a torsion spring 28 is fixedly installed between the rotating shaft 27 and the adjustment rod 20. The torsion spring 28 allows the paperboard 26 and the adjustment rod 20 to maintain a nearly vertical state in a natural state. When the third connecting rod 21 is installed in the lower mounting hole, the paperboard 26 rotates to fit the mounting vertical plate 16, and the edge of the paperboard 26 that fits the mounting vertical plate 16 slides down along the mounting vertical plate 16, and finally one surface of the mounting vertical plate 16 fits on the mounting vertical plate 16, and the paper placed in the paperboard is vertical at this time.

[0027] In this embodiment, a fixing plate 30 is slidably mounted on the paperboard 26, and the fixing plate 30 and the paperboard 26 clamp the paper. The paper is clamped by the fixing plate 30, and the fixing plate 30 is loosened during vibration alignment, and the fixing plate 30 is clamped after alignment, so as to ensure that the paper will not fall off again during the process of moving to the cutting assembly. A fixing electric cylinder 31 is fixedly mounted on the first alignment plate 37 and the second alignment plate 38, and a matching plate 33 is fixedly mounted on the fixing plate 30, and an inclined groove 34 is arranged on the matching plate 33. A matching shaft 32 is fixedly mounted on the cylinder arm of the fixing electric cylinder 31, and the matching shaft 32 cooperates with the inclined groove 34 to control the sliding of the fixing plate 30.

[0028] In this embodiment, two hinge holes are arranged vertically on the side of the mounting plate 16, and a grounding metal plate 23 and a vibrator 1 24 are fixedly mounted on the bottom of the mounting plate 16. A gap is set between the first alignment plate 37 and the second alignment plate 38, and the grounding metal plate 23 is inserted into the gap to abut against the paper. When the third connecting rod 21 is installed in the mounting hole close to the lower side, the bottom of the paperboard 26 will contact the grounding metal plate 23 and the vibrator 1 24. Through the above technical solution, the vibration frequency and amplitude of the vibrator 1 24 and the vibrator 2 25 are different, and the grounding through the grounding metal plate 23 can reduce the static electricity between the papers, making it easier to align the papers.

[0029] In this embodiment, the cutting assembly includes a positioning plate 12, the positioning plate 12 is slidably mounted on the cutting table 2, a moving plate 14 is fixedly mounted on the end of the positioning plate 12, a positioning groove 15 is arranged on the lower side of the moving plate 14, and a rotating shaft 27 approaches the moving plate 14 to push the positioning plate 12, and after the rotating shaft 27 is fitted with the positioning groove 15, the paperboard 26 is fitted with the cutting table 2. Through the above technical scheme, since the distance between the third connecting rod 21 and the adjusting rod 20 is adjustable, the position of the paperboard 26 on the cutting table 2 is different, and the cooperation between the moving plate 14 and the rotating shaft 27 can ensure that the position of the cutting assembly is always relatively fixed with the position of the paper, thereby ensuring the accuracy of the cutting position. A sliding shaft 4 is fixedly mounted on the positioning plate 12, and a side support plate 3 is fixedly mounted on the cutting table 2, and the side support plate 3 is slidably connected with the sliding shaft 4, and a reset spring 5 is fixedly mounted between the sliding shaft 4 and the side support plate 3. Two mounting columns 6 are fixedly mounted on the positioning plate 12, and a vertical electric cylinder 7 is fixedly mounted on the mounting column 6. The cylinder arm of the vertical electric cylinder 7 drives a horizontal electric cylinder 8, and a cutting knife 10 is fixedly mounted on the cylinder arm of the horizontal electric cylinder 8. A pressing plate 11 is slidably mounted on the cutting knife 10, and a pressing spring 9 is fixedly mounted between the pressing plate 11 and the cutting knife 10. The cutting knife 10 cuts after the pressing plate 11 presses the paper. Through the above technical solution, the horizontal electric cylinder 8 can control the cutting position of the cutting knife 10. When the cutting knife 10 is close to the fixed plate 30 for cutting, the pressing plate 11 contacts the fixed plate 30. When the cutting knife 10 cuts the position outside the fixed plate 30, the pressing plate 11 presses the extended paper for cutting, ensuring that the paper will not swing during cutting, resulting in inaccurate cutting.

[0030] Working principle: first adjust the position. According to the different qualities of the paper, when cutting thicker paper, place the third connecting rod 21 in the upper mounting hole. The distance between the adjustment rod 20 and the third connecting rod 21 is shorter. The paperboard 26 will contact and vibrate with the vibrator 25. At the same time, the paperboard 26 will be in an inclined state because thick paper is heavier and easier to align. If you want to cut thinner paper, you need to place the third connecting rod 21 in the lower mounting hole to fit the paperboard 26 with the vibrator 24. The vibration frequency of the vibrator 24 is large and the amplitude is small. The grounding metal plate 23 contacts the paper to eliminate static electricity.

[0031] Put the paper between the paperboard 26 and the fixed plate 30 without pressing it, start the vibrator 1 24 or the vibrator 2 25 to start vibrating, the paper is gradually aligned and fits with the first alignment plate 37 and the second alignment plate 38, then start the drive motor 17, the drive motor 17 drives the paperboard 26 to rotate through the parallelogram connecting rod, the rotating shaft 27 contacts the moving plate 14, drives the cutting assembly to slide and stretches the reset spring 5, the side of the cutting table 2 is equipped with a side support plate 3, the sliding shaft 4 slides on the side support plate 3, and finally the drive motor 17 fits with the positioning groove 15, the paperboard 26 fits with the cutting table 2, then start the vertical electric cylinder 7 to descend, the horizontal electric cylinder 8 adjusts the front and rear position, the cutting knife 10 falls to cut, and the squeezing plate 11 will press the paper exposed outside the fixed plate 30 during the process. Cut two edges, then encapsulate the uncut edge, and finally trim the uncut edge.

[0032] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
