Description

Technical Field

[0001] The utility model relates to the technical field of composite paper cutting, in particular to a composite paper cutting machine. Background Technique

[0002] Composite paper refers to a kind of composite processed paper formed by laminating paper, paperboard and other materials (such as plastics, aluminum foils, cloth, etc.) through adhesives. During the processing, in order to obtain composite paper sheets of the required length, the composite paper will be conveyed to a cutting machine by a conveyor and cut. The cutting machine cuts at regular intervals to achieve equal-length cutting of the composite paper conveyed to the cutting machine.

[0003] During the cutting process of composite paper, the thicker the paper, the more fibers are contained in the cross-section, so the more paper scraps are carried out by the cutting, which is likely to cause paper scraps to adhere to the cutting part of the cutting knife. At present, it is not easy to clean the paper scraps on the cutting knives of most cutting machines during the cutting process, which affects the continuous cutting of the cutting knives. Sometimes, the same cutting machine cuts composite papers with different widths, and most cutting machines only install a cutting knife with a longer length to meet the cutting of composite papers with different widths. Using a cutting knife with a longer length to cut narrow-width paper may cause waste of the blade, because the length of the blade is much greater than the width of the paper to be cut, so that part of the blade is not fully utilized, while a shorter cutting knife can better adapt to this cutting requirement and improve the utilization rate of the blade. Content of the Utility Model

[0004] The purpose of the utility model is to provide a composite paper cutting machine to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A composite paper cutting machine includes two support columns fixedly installed on the ground. Between the tops of the two support columns, a feeding plate and a cutting plate are fixed. Between the feeding plate and the cutting plate, two conveying rollers for conveying composite paper are arranged. At the tops of the two support columns, a paper pressing mechanism for fixing the cutting position of the composite paper is provided. Between the cutting plate and the two support columns, a support plate is fixed. On the top of the support plate, a cutting mechanism for cutting paper is provided. The cutting mechanism includes a support box slidably supported on the support plate. At both ends of the support box, support seats are fixed. Between the two support seats, a knife roller is rotatably connected. On the outer side of the knife roller, a plurality of cutting knives with different lengths are fixedly arranged at equal angles in a ring shape. On the top surface of the support plate, a cylinder one for driving the support box to move up and down is fixed.

[0007] Furthermore, between the bottoms of the two support seats, a brush roller is rotatably connected. On the top of one support seat, a motor two for driving the knife roller to rotate is fixed. On the bottom of the other support seat, a motor three for driving the brush roller to rotate is fixed.

[0008] Furthermore, both sides inside the support box are fixedly provided with dust suction pipes through openings. A connecting pipe is fixedly connected between the two dust suction pipes, and the connecting pipe is fixedly connected to the dust suction pipe of an external vacuum cleaner through a hose.

[0009] Furthermore, two first brushes are fixedly arranged on the top of the support box, two first support pipes are fixedly arranged on the top surface of the pallet, and a first support rod fixedly connected to the support box is slidably connected inside the first support pipe.

[0010] Furthermore, a chassis is fixedly arranged on the outer side of a support column. The chassis is fixedly provided with two first motors respectively used for driving the conveying rollers at corresponding positions to rotate, and through holes are formed in the top surface of the cutting plate.

[0011] Furthermore, the paper pressing mechanism comprises a connecting plate fixedly connected to the support column. A second air cylinder is fixedly arranged on the bottom surface of the connecting plate, an output end of the second air cylinder is fixedly provided with a pressing block, and a notch is formed in the bottom surface of the pressing block.

[0012] Furthermore, two second support pipes are fixedly arranged at both ends of the bottom surface of the connecting plate, and a second support rod fixedly connected to the pressing block is slidably connected inside the second support pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The composite paper is conveyed to the position between the two conveying rollers by an external conveyor. The two conveying rollers convey the composite paper onto the cutting plate. The first air cylinder drives the support box to move upward, so that the guide roller drives the vertically arranged cutting knife to move upward through the cutting plate. At the same time, the second air cylinder drives the pressing block to move downward. The cutting knife and the pressing block cooperate to cut the composite paper. According to the width and length of the composite paper, the second motor can be driven to drive the knife roller to rotate in advance below the cutting plate, and the cutting knife with a length matching the width of the composite paper is replaced to the vertical state, so that composite papers with different widths can be cut by cutting knives with different lengths matching, and the utilization rate of the cutting edge is improved.

[0015] 2. The first air cylinder drives the knife roller on the support box to move downward, so that the cutting knife moves to below the cutting plate. The second motor drives the knife roller to drive the cutting knife to rotate, so that the brush on the brush roller can clean the paper scraps on the cutting knife. At the same time, the third motor drives the brush roller to rotate, further improving the efficiency of the brush roller in cleaning the paper scraps on the cutting knife. When a cutting knife at a certain position is damaged, the intact spare cutting knife can be rotated to the cutting position by means of the rotation of the knife roller, realizing rapid replacement of the cutting knife without stopping the machine.

[0016] 3. By fixedly arranging two first brushes inside the support box, the first brushes can contact with the rotating brush roller, facilitating cleaning and combing the paper scraps attached to the brush roller into the support box. Then, the external vacuum cleaner sucks air through the connecting pipe into the two dust suction pipes, so that the paper scraps inside the support box can be sucked and cleaned by the dust suction pipes, facilitating collection of impurities such as paper scraps and dust.

[0017] 4. By arranging multiple cutting knives below the composite paper for paper cutting, the paper scraps falling off the cleaning cutting knives will not fall onto the composite paper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Example 1, please refer to Figures 1-5, in the embodiment of the present utility model, a composite paper cutting machine includes two support columns 100 fixedly installed on the ground. Between the tops of the two support columns 100, a feeding plate 110 and a cutting plate 120 are fixed. Between the feeding plate 110 and the cutting plate 120, two conveying rollers 130 for conveying composite paper are arranged. At the tops of the two support columns 100, a paper pressing mechanism 200 for fixing the cutting position of the composite paper is provided. Between the cutting plate 120 and the two support columns 100, a support plate 140 is fixed. At the top of the support plate 140, a cutting mechanism 300 for cutting paper is provided. The cutting mechanism 300 includes a support box 310 slidably supported on the support plate 140. At both ends of the support box 310, support seats 320 are fixed. Between the two support seats 320, a knife roller 330 is rotatably connected. On the outer side of the knife roller 330, a plurality of cutting knives 340 with different lengths are fixedly arranged at equal angles in a ring shape. On the top surface of the support plate 140, a cylinder 141 for driving the support box 310 to move up and down is fixed.

[0026] Specifically, by installing a plurality of cutting knives 340 with different lengths on the knife roller 330, as the knife roller 330 rotates, the cutting knives 340 with different lengths can be used to cut the composite paper with different widths in a matching manner, which is beneficial to improving the utilization rate of the cutting knives 340. And when a certain cutting knife 340 is damaged, the spare cutting knife 340 can also be rotated to the cutting position by means of the rotation of the knife roller 330, realizing automatic replacement of the cutting knife 340 without stopping the machine. By rotatably connecting a brush roller 321 below the knife roller 330, during the rotation of the knife roller 330 with a plurality of cutting knives 340, the cutting knives 340 can be in contact with the bristles of the brush roller 321, and at the same time, the brush roller 321 rotates, which is beneficial to automatically cleaning the paper scraps attached to the cutting knives 340.

[0027] As Figure 4 shown, in this embodiment, between the bottoms of the two support seats 320, a brush roller 321 is rotatably connected. At the top of one support seat 320, a motor 322 for driving the knife roller 330 to rotate is fixed. At the bottom of the other support seat 320, a motor 323 for driving the brush roller 321 to rotate is fixed.

[0028] In this embodiment, during the rotation of the knife roller 330 with the cutting knives 340, the cutting knives 340 are in contact with the bristles on the outer side of the brush roller 321, and the bristles can clean the paper scraps on the cutting knives 340. During this process, the motor 323 can drive the brush roller 321 to rotate synchronously, so that the brush roller 321 can actively rotate outside the cutting knives 340 to clean the cutting knives 340, which is beneficial to improving the efficiency of cleaning the cutting knives 340.

[0029] As Figure 3As shown, in this embodiment, a chassis 150 is fixed to the outside of a support column 100. Two motors one for driving the corresponding conveying rollers 130 to rotate are fixed to the chassis 150. A through hole 121 is formed in the top surface of the cutting plate 120.

[0030] In this embodiment, the motor one is used to drive the conveying roller 130 to rotate so that the two conveying rollers 130 can convey the composite paper to the cutting position. The through hole 121 facilitates the passing of the cutting knife 340, enabling the cutting knife 340 to move upward from below the composite paper to cut the composite paper.

[0031] As Figure 2 shown, in this embodiment, the paper pressing mechanism 200 includes a connecting plate 210 fixedly connected to the support column 100. A cylinder two 220 is fixed to the bottom surface of the connecting plate 210. The output end of the cylinder two 220 is fixed with a pressing block 230, and a notch 231 is formed in the bottom surface of the pressing block 230.

[0032] In this embodiment, during the process of the cutting knife 340 moving upward to cut the paper, the cylinder two 220 drives the pressing block 230 to move downward synchronously. The pressing block 230 cooperates with the cutting knife 340 to cut the composite paper. The notch 231 on the pressing block 230 facilitates the entry of the blade, providing a moving space for the cutting knife 340 to cut.

[0033] As Figure 2 shown, in this embodiment, two support tubes two 240 are fixed to both ends of the bottom surface of the connecting plate 210. A support rod two fixedly connected to the pressing block 230 is slidably connected inside the support tube two 240. The sliding of the support rod two inside the support tube two 240 enables the pressing block 230 to move up and down stably.

[0034] Embodiment Two, on the basis of Embodiment One, in order to collect and clean the paper scraps on the bristles of the brush roller 321.

[0035] As Figure 4 and Figure 5 shown, in this embodiment, two brush one 312 are fixed to the top of the support box 310. Two support tubes one 142 are fixed to the top surface of the support plate 140. A support rod one fixedly connected to the support box 310 is slidably connected inside the support tube one 142.

[0036] In this embodiment, the brush one 312 facilitates contact with the bristles on the outside of the brush roller 321, facilitating the combing of the paper scraps on the brush roller 321 into the support box 310. The sliding of the support rod one inside the support tube one 142 enables the support box 310 to move up and down stably.

[0037] As Figure 5As shown, in this embodiment, dust suction pipes 311 are fixedly installed by opening doors on both sides inside the support box 310. A connecting pipe 3111 is fixedly connected between the two dust suction pipes 311. The connecting pipe 3111 is fixedly connected to the dust suction pipe 311 of an external vacuum cleaner through a hose.

[0038] In this embodiment, a hose is fixedly connected to the pipe outside the connecting pipe 3111. The hose is connected to the dust suction end of an external vacuum cleaner. The length of the hose meets the length requirement for the support box 310 to move up and down with the connecting pipe 3111. The vacuum cleaner sucks air into the support box 310 through the hose and the connecting pipe 3111, so that the paper scraps falling into the support box 310 can be sucked and collected.

[0039] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
