Description

Technical Field

[0001] The invention relates to the technical field of light paper cutting devices, and in particular to a cutting dust collecting device for light paper production. Background Art

[0002] Light paper is light offset paper, which is a cheap paper type. It is high quality, light, low price and high mechanical pulp content. Because it is easy to turn yellow, the original color tone can protect the eyes of readers, especially the elderly and children, so that they can protect their eyesight from damage when reading. Because it is very light and thin, it is easy for readers to carry and read.

[0003] However, light paper has a poor texture and is loose, which easily stirs up a lot of dust during the production and cutting process. This dust will affect the workshop environment, the health of operators and the operating life of equipment in the workshop. Therefore, the debris generated by cutting needs to be processed simultaneously during cutting to avoid damage to the surrounding environment and personnel.

[0004] Chinese patent announcement number CN213197826U discloses a cutting dust collection device for light paper production, including a cutting machine, a workbench, a supporting platform, a cutter and a cutter driving device, a paper scraps separation component is arranged between the workbench and the cutting machine, the paper scraps separation component includes a separation seat, a paddle plate, a rotating shaft and a reduction motor, a chip collecting box is arranged below the workbench, a dust collecting plate is arranged on the supporting platform, a plurality of dust collecting plugs are arranged in the dust collecting plate, a dust collecting groove is arranged below the dust collecting plate, a first air inlet and a second air inlet are arranged on the side of the dust inlet, a dust collector is arranged at the output end of the first air inlet, a dust collecting box is connected to the second air inlet through an air inlet duct, and the dust collecting box is arranged on the cutter.

[0005] The device in the above document uses a paper scrap removal component to turn the paper scraps generated by cutting into a chip collection box, which is beneficial to reducing workload and improving work efficiency; the dust collector can effectively collect the dust carried by the paper pile and the dust generated by cutting, improve the working environment, and has strong practicality and high utilization rate.

[0006] However, in actual use, a large amount of high-fiber dust will be generated during the cardboard cutting process. This dust will block the air flow channel. If it is operated for a long time, the air flow will be blocked, affecting the collection effect.

[0007] Furthermore, the paper scraps removing assembly used in the above-mentioned documents can only clean the paper scraps at the bottom of the light paper stack when taking out the light paper stack.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0039] like Figure 1As shown, a cutting dust collection device for light paper production includes a cutting chamber 2, a dust collecting structure 1 is fixedly connected to the lower end of the cutting chamber 2, a hydraulic cylinder 5 is fixedly connected to the upper end of the cutting chamber 2, the output end of the hydraulic cylinder 5 passes through the upper end of the cutting chamber 2 and extends to the inner cavity of the cutting chamber 2 and is fixedly connected to a positioning and clamping structure 4, a cutting dust cleaning structure 6 fixedly connected to the positioning and clamping structure 4 is slidably connected to the front side wall of the inner cavity of the cutting chamber 2, and a feeding support plate 3 is fixedly connected to the upper front end of the dust collecting structure 1.

[0040] It should be noted that the hydraulic cylinder 5 is a conventional hydraulic telescopic device, which extends or retracts its telescopic rod by injecting or extracting hydraulic oil. This structure has been widely used in the prior art. In the present invention, it is only used to realize the telescopic function, and its internal structure, operating principle, oil circuit, circuit connection method and control method are not described in detail.

[0041] In addition, buttons for controlling the hydraulic cylinder 5 are provided on the left and right sides of the front of the cutting chamber 2, which need to be pressed simultaneously to drive the hydraulic cylinder 5 to operate. This is a conventional safety control method in cutting equipment. This driving method is relatively conventional and will not be displayed or repeated in the present invention.

[0042] During the operation of this embodiment, the stacked light paper pile is first pushed into the positioning and clamping structure 4 in the inner cavity of the cutting chamber 2 through the feed pallet 3, and the light paper pile is sorted and pressed and fixed by the action of the hydraulic cylinder 5 on the positioning and clamping structure 4. At the same time, the light paper is cut by the action of the hydraulic cylinder 5 and the cutting dust cleaning structure 6. After the cutting is completed, the hydraulic cylinder 5 is lifted and the cutting dust cleaning structure 6 is used to clean the dust on the cut surface of the light paper, thereby reducing the dust residue in the light paper and improving the utilization efficiency. Embodiment 2

[0043] On the basis of the first embodiment, the present embodiment drives the positioning assembly 42 to operate from the left and right sides to sort the light paper pile through the cooperation of the hydraulic cylinder 5 and the U-shaped bracket 41, so that the light paper pile to be cut is more neat, and burrs on the cut surface caused by paper misalignment during the cutting process are prevented, thereby reducing the influence of these burrs on the paper cutting quality and improving the product quality;

[0044] At the same time, the U-shaped bracket 41 and the spring buffer rod 43 cooperate to compress and fix the paper pile, so as to prevent the paper pile from collapsing due to unilateral pressure during the cutting process.

[0045] Specifically, to achieve the compression and fixation of the paper pile, refer to Figure 2 and Figure 3The positioning and clamping structure 4 includes a U-shaped bracket 41 fixedly connected to the output end of the hydraulic cylinder 5, and positioning components 42 are symmetrically fixedly connected on both sides of the vertical part of the U-shaped bracket 41. A bottom support 45 is fixedly connected to the bottom wall of the inner cavity of the cutting chamber 2, and a limit plate 46 is fixedly connected to the rear part of the upper end of the bottom support 45. The outer surface of the limit plate 46 is slidably connected to a U-shaped connecting rod 47 fixedly connected to the lower end of the vertical part of the U-shaped bracket 41. The front end of the U-shaped connecting rod 47 is fixedly connected to the cutting dust cleaning structure 6, and a spring buffer rod 43 is fixedly connected to the lower end of the horizontal part of the U-shaped bracket 41, and a pressure plate 44 is fixedly connected to the lower end of the piston rod of the spring buffer rod 43.

[0046] The piston rod of the hydraulic cylinder 5 extends to drive the U-shaped bracket 41 to descend and simultaneously drives the spring buffer rod 43 and the positioning assembly 42 to descend, thereby arranging and fixing the paper pile. The bottom support 45 is suitable for supporting the paper pile, and the limiting plate 46 at the rear thereof plays a limiting role when the paper pile is pushed in.

[0047] Further, in order to realize the arrangement of the paper pile, see Figure 3 , Figure 4 and Figure 5 The positioning assembly 42 includes an L-shaped rod 421 and a T-shaped plate 423 fixedly connected to the vertical part of the U-shaped bracket 41; the lower end of the vertical part of the positioning assembly 42 is fixedly connected to a driving slider 422 that is slidably connected to the inner wall of the cutting chamber 2 on the same side; the inner surface of the horizontal part of the driving slider 422 is slidably connected to a U-shaped limiting rod 424 that is fixedly connected to the inner wall of the cutting chamber 2 on the same side; the vertical part of the T-shaped plate 423 is symmetrically fixedly connected to a compression spring 426; the end of the compression spring 426 away from the T-shaped plate 423 is fixedly connected to a contact plate 425; the end of the contact plate 425 close to the T-shaped plate 423 is symmetrically fixedly connected to a limiting support rod 427 that is slidably connected to the T-shaped plate 423.

[0048] Further, in order to achieve the paper pile to be arranged in advance before the pressure plate 44 arrives, the pressure is maintained after the pressure plate 44 reaches the upper part of the paper pile, see Figure 5 The driving slider 422 is in a Z shape, the width of the upper part is greater than the width of the lower part, and the junction is a smooth slope. The difference between the upper and lower widths is greater than the distance between the contact plate 425 and the edge of the bottom support 45.

[0049] The U-shaped bracket 41 descends and drives the L-shaped rod 421 to descend. The lower part of the L-shaped rod 421 has a certain advance amount relative to the lower end of the pressing plate 44. The height difference is determined by the thickness range of the paper pile to be processed in the specific processing process.

[0050] The L-shaped rod 421 descends and drives the driving slider 422 to slide downward on the inner wall of the cutting chamber 2, thereby driving the T-shaped plate 423 to slide along the direction limited by the U-shaped limiting rod 424 through the change in its width, thereby pushing the contact plate 425 toward the direction of the paper pile through the compression spring 1 426 and clamping the paper pile from both sides. Due to the buffering of the compression spring 1 426, the contact between the contact plate 425 and the paper pile is not rigid, and the paper pile can be slowly pushed to be folded into a neat state, and the auxiliary pressing plate 44 fixes the paper pile from the left and right sides;

[0051] The spring buffer rod 43 can retract under pressure. It is a conventional telescopic rod with a built-in spring. In the initial state, the lower end of the pressure plate 44 is lower than the lower end of the cutting part in the cutting and dust cleaning structure 6, and there is a certain margin. After the pressure plate 44 is in place, the U-shaped bracket 41 continues to descend so that the pressure plate 44 is compressed. At this time, although the driving slider 422 continues to descend, it will no longer drive the T-shaped plate 423 to slide. The U-shaped bracket 41 drives the U-shaped connecting rod 47 to press down, thereby driving the cutting and dust cleaning structure 6 to move, and cut the gathered and fixed paper pile. Embodiment 3

[0052] On the basis of the second embodiment, this embodiment further utilizes the cooperation between the U-shaped connecting rod 47 and the cutting knife 62 to cut the paper pile. After the cutting is completed, the cooperation between the roller 631 and the dust cleaning component 65 is used to drive the dust cleaning component 65 to slide out of the isolation door 61 and approach the cutting surface. The paper on the cutting surface is moved by the action of the material shifting component 653, and the dust collecting structure 1 and the connecting pipe 2 655 are used to clean the dust on the cutting surface through the dust collection box 654, thereby reducing the dust residue on the surface and gaps of the paper, improving the cleanliness and thus ensuring the product quality.

[0053] Specifically, to achieve the cutting dust cleaning of the paper pile, refer to Figure 6 and Figure 7 The cutting dust cleaning structure 6 includes an isolation door 61 that is slidably connected to the cutting chamber 2 through a pulley and a pulley groove and the inner wall of the cutting chamber 2, and a cutting knife 62 that is fixedly connected to the front end of the U-shaped connecting rod 47. The isolation door 61 is symmetrically provided with a slide groove 64 that communicates with its inner cavity on one side near the U-shaped connecting rod 47. The end of the cutting knife 62 near the isolation door 61 is rectangularly distributed and fixedly connected with four limit sliders 63 that are slidably connected to the inner surface of the slide groove 64 on the same side. The bottom walls of the inner cavities of the two slide grooves 64 are fixedly connected with compression springs 2 that are fixedly connected to the limit sliders 63 located at the bottom. 66. A dust cleaning component 65 is provided in the inner cavity of the isolation door 61. The two limit sliders 63 located at the bottom are rotatably connected with rollers 631 that are slidably connected to the dust cleaning component 65 on one side that is close to each other.

[0054] After the pressing plate 44 is in place, the cutting knife 62 will follow the U-shaped connecting rod 47 to drop above the paper pile. Before this, the cutting knife 62 will press the isolation door 61 to drop under the action of the compression spring 2 66. Before the cutting blade of the cutting knife 62 drops above the paper pile, the cutting knife 62 will isolate the inner cavity of the cutting chamber 2 from the outside to avoid dust splashing caused by cutting. The chute 1 64 is used to limit the running path of the cutting knife 62 to vertical up and down movement through the limit slider 63, and at the same time, the dust cleaning component 65 is used to link the movement state of the dust cleaning component 65 and the cutting knife 62.

[0055] Further, in order to clean the dust generated by cutting in the paper pile, refer to Figure 8 The dust cleaning component 65 includes driven plates 651 symmetrically distributed on the left and right and slidably connected to the inner cavity of the isolation door 61. A Z-shaped slide groove 652 is provided on the side away from each other of the two driven plates 651. The inner surface of the Z-shaped slide groove 652 is slidably connected to the outer surface of the Z-shaped slide groove 652 on the same side. The ends of the two driven plates 651 close to each other are symmetrically fixedly connected with dust collection boxes 654 through the back plate. The lower end of the dust collection box 654 is slidably connected to a connecting pipe 2 655 fixedly connected to the bottom wall of the inner cavity of the isolation door 61. The connecting pipe 2 655 is connected to the dust collecting structure 1. The ends of the two driven plates 651 close to each other are commonly provided with a material shifting component 653.

[0056] The driven plate 651 slides in the inner cavity of the isolation door 61 and a Z-shaped groove 652 matched with the roller 631 is provided on the side close to the roller 631 on the same side. When the rollers 631 on both sides slide in the Z-shaped groove 652, the driven plate 651 will be driven to slide in the isolation door 61 along the path of the Z-shaped groove 652. At the same time, the dust collection box 654 moves toward the direction close to the paper pile, so as to fit the cutting surface of the paper pile. At this time, the inner cavity of the dust collection box 654 is connected with the lower connecting pipe 2 655, and the dust collection structure 1 provides suction to the inner cavity of the dust collection box 654, thereby sucking dust into the inner cavity of the dust collection structure 1.

[0057] Further, to clean the dust hidden in the gaps between the papers, refer to Fig. 9 The material-prying component 653 includes a transmission shaft 6532 rotatably connected to the isolation doors 61 on both sides and a second driving motor 6534 fixedly connected to the lower end of the dust collection box 654 through a motor seat. Three circulating belts 6531 are linearly distributed and wound around the outer surface of the transmission shaft 6532. The lower part of the inner surface of the circulating belt 6531 is wound around a pulley 6535. The two pulleys 6535 close to the driven plate 651 are rotatably connected to the driven plate 651. The lower end of the dust collection box 654 is symmetrically fixedly connected to a bearing bracket 6533 supporting the pulley 6535. One of the bearing brackets 6533 is transmission-connected to the second driving motor 6534. A plurality of rubber paddles 6536 are curvedly distributed and fixedly connected to the outer surfaces of the three circulating belts 6531.

[0058] The dust generated by cutting will fall into the gaps between the papers, and it is impossible to clean the dust in the gaps by simply sweeping;

[0059] One of the pulleys 6535 is driven to rotate by the driving motor 2 6534, and all the circulating belts 6531 are driven to rotate at the same time by the transmission shaft 6532. At this time, the rubber paddle 6536 on the surface of the circulating belt 6531 will pry the light paper apart one by one, thereby separating the gaps in the light paper, and then the dust in these gaps is extracted by the dust collection box 654 to reduce the dust residue between the papers. Embodiment 4

[0060] On the basis of the third embodiment, the present embodiment utilizes the action of the fan 16 to extract the air in the connecting pipe 2 655 through the dust filter assembly 15 and the connecting pipe 1 14, so that the dust absorbed by the material removing component 653 is sucked into the upper part of the inner cavity of the dust collecting chamber 11 through the action of the connecting pipe 2 655 and the connecting pipe 1 14, and the dust is filtered and adsorbed by the dust filter assembly 15, and the dust is scraped off and falls into the lower part of the inner cavity of the dust collecting chamber 11 through the action of the scraping brush plate 157 and the anti-collapse plate 154, so as to ensure the permeability of the isolation net 155 and prevent the paper dust from blocking the ventilation path of the isolation net 155, causing the wind path to be blocked and affecting its dust collection efficiency.

[0061] Specifically, to achieve dust collection, refer to Fig.10 The dust collecting structure 1 includes a dust collecting chamber 11, a maintenance door 12 is symmetrically connected to the front of the inner cavity of the dust collecting chamber 11, a dust filter assembly 15 is fixedly connected to the middle of the inner cavity of the dust collecting chamber 11, and an isolation plate 13 fixedly connected to the inner wall of the dust collecting chamber 11 is arranged in front of the dust filter assembly 15, a fan 16 connected to the outside is fixedly connected to the rear of the inner cavity of the dust collecting chamber 11, a connecting pipe 14 connected to the connecting pipe 2 655 is fixedly connected to the top wall of the inner cavity of the dust collecting chamber 11, and a waste port 17 connected to the inner cavity of the cutting chamber 2 is opened at the upper part of the inner cavity of the dust collecting chamber 11.

[0062] The fan 16 exhausts air outwards. At this time, the large pieces of shredded paper produced by the cutting knife 62 can be drawn into the upper part of the isolation plate 13 in the inner cavity of the dust collecting chamber 11 under the action of the waste port 17, and the dust and shredded paper are driven to fall into the lower part of the isolation plate 13 for storage through the action of the isolation plate 13 and the dust filter assembly 15.

[0063] Further, to achieve the filtration and collection of dust, refer to Fig.11The dust filter assembly 15 includes a support frame 152, the inner surface of the support frame 152 is connected to a drive shaft 156 which rotates symmetrically up and down, the outer surfaces of the two drive shafts 156 are commonly wound and connected to an isolation net 155, the lower part of the inner wall of the support frame 152 located on the inner side of the isolation net 155 is fixedly connected to an anti-collapse plate 154, the lower part of the rear end of the support frame 152 is fixedly connected to a shielding plate 153, the front part of the inner cavity of the support frame 152 located below the isolation plate 13 is linearly fixedly connected to a plurality of scraper brush plates 157 that can fit with the surface of the isolation net 155, and the lower left end of the support frame 152 is fixedly connected to a drive motor 151 which is transmission-connected to the drive shaft 156 located at the bottom.

[0064] Further, in order to clean the dust on the surface of the isolation net 155, refer to Fig.11 The front end of the anti-collapse plate 154 is in contact with the inner surface of the isolation net 155, and the upper side of the part where the scraper brush plate 157 is in contact with the isolation net 155 is a plane, and the lower side is a brush.

[0065] The isolation net 155 rotates between the two support frames 152 under the action of the driving motor 151. The two sides of the upper isolation net 155 are connected, and the suction force generated by the fan 16 will pass through the upper part of the isolation net 155, so that the dust and shredded paper strips in the upper part of the inner cavity of the dust collecting chamber 11 are attached to the surface of the isolation net 155. At this time, the isolation net 155 gradually crosses the isolation plate 13 to reach the lower part of the isolation plate 13 under the movement of the isolation net 155. At this time, under the action of the anti-collapse plate 154 and the shielding plate 153, the isolation net 155 at the lower part will not be affected by the fan 16, and some shredded paper strips and dust will fall into the lower part of the inner cavity of the dust collecting chamber 11 through the inclined surface of the scraper brush plate 157, and those that are tightly attached will be swept down by the brush on the scraper brush plate 157 and fall into the lower part of the inner cavity of the dust collecting chamber 11, thereby realizing the collection of dust and shredded paper strips.
