Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard raw material feeding technology, specifically to a raw paper feeding device for corrugated cardboard production that prevents materials from tilting. Background Technology

[0002] In the production of corrugated cardboard, raw material feeding is a crucial step. However, in existing technologies, the raw materials for corrugated cardboard often shift during feeding, which negatively impacts subsequent production processes and product quality.

[0003] In existing corrugated cardboard production raw paper feeding devices, a common problem is the difficulty in automatically centering and aligning the material during transport. This is mainly due to differences in the physical properties of the material itself (such as thickness, hardness, and weight), as well as limitations in the precision and stability of the conveying equipment. When the material moves on the conveyor belt, without an effective centering and alignment mechanism, it is prone to deviation. This not only affects the normal operation of subsequent processes but may also lead to equipment damage or production interruption, thereby increasing production costs and reducing production efficiency.

[0004] Chinese Patent Publication No. CN216836374U discloses a paper feeding device for corrugated cardboard production. This device includes a fastening mechanism, a support mechanism under the swing arm, and a conveying device on one side of two vertical plates. The conveying device and fastening mechanism are matched with the paper roll. Through the cooperation of these mechanisms, this invention not only automatically feeds the paper roll without manual operation, reducing workload and increasing intelligence, but also ensures efficient feeding. Furthermore, it guarantees stability when lifting the paper roll, preventing instability during feeding and ensuring processing efficiency and quality. The force required to lift the paper roll is shared by multiple components, reducing the burden on the equipment when lifting it alone, decreasing wear during use, and extending the overall service life of the equipment.

[0005] However, in actual use, the above structure is not convenient for automatically centering and limiting the material when feeding it, which may cause the material to deviate during feeding. This deviation will cause the corrugated cardboard to be unable to be properly aligned or positioned in subsequent processes, thus affecting the cutting, bonding and forming processes of the cardboard. Utility Model Content

[0006] To address the aforementioned issues, a paper feeding device for corrugated cardboard production is provided to prevent material tilting. Through the coordinated operation of the anti-deviation unit and the push-limiting unit, the problem of material deviation during the conveying process is solved.

[0007] To address the existing technical problems, this utility model provides a paper feeding device for corrugated cardboard production that prevents material tilting. The device includes a housing and a conveying unit disposed on the housing for conveying materials, as well as an anti-deviation unit disposed on the housing for preventing deviation during material conveying.

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] See Figures 1-3 As shown, a paper feeding device for corrugated cardboard production that prevents material tilting includes a housing 1 and a conveying unit 2 disposed on the housing 1 for conveying materials, and an anti-deviation unit 3 disposed on the housing 1 for preventing deviation during material conveying. The anti-deviation unit 3 includes a pair of connecting plates 31 disposed on the housing 1 and a push limiting unit 4 for driving the connecting plates 31 to move, and a cleaning unit 5 disposed on the housing 1 for cleaning external dust or impurities of the material during conveying.

[0029] The conveying unit 2 includes a frame 21, a first rotating roller 22, a second rotating roller 23, and a third rotating roller 24. The frame 21 is mounted on the housing 1. The first rotating roller 22 and the second rotating roller 23 are respectively mounted on the frame 21. The first rotating roller 22 is used to feed materials, and the second rotating roller 23 is used to discharge processed materials. The third rotating roller 24 is rotatably mounted on the housing 1 and located below the cleaning unit 5. The third rotating roller 24 is used to restrict, support, and press the cleaned materials. The materials pass through the first rotating roller 22, the anti-deviation unit 3, the push-limiting unit 4, the cleaning unit 5, the third rotating roller 24, and the second rotating roller 23 in sequence, completing the anti-deviation and cleaning work during the material conveying process. When the materials are conveyed on the first rotating roller 22 and pass through the anti-deviation unit 3, the anti-deviation unit 3 can automatically correct the materials during the conveying process. Furthermore, by setting up the push-limiting unit 4, the corrected materials can be further limited, further improving the stability of the materials during the conveying process. Finally, the cleaning unit 5 can clean the dust and impurities on the materials.

[0030] See Figure 4As shown, the anti-deviation unit 3 also includes a bearing rotating rod 32 and a rotating clamping sleeve 33; there are multiple bearing rotating rods 32 and they are equidistantly arranged on the connecting plate 31; the rotating clamping sleeves 33 are rotatably arranged on the bearing rotating rods 32 and there are multiple rotating clamping sleeves 33, which are arranged from bottom to top and are relatively close to the material conveying direction, and the rotating clamping sleeves 33 are conical in shape.

[0031] When the material is conveyed on the first rotating roller 22, the material can contact and abut against the rotating clamping sleeve 33 rotatably set on the bearing rotating rod 32. When the material continues to be conveyed, since there are multiple rotating clamping sleeves 33 along the material conveying direction, and they are arranged from bottom to top and are relatively close to each other in sequence, the material can be restricted by the rotating clamping sleeves 33 during the conveying process. As the material passes through these rotating clamping sleeves 33 in sequence, it will be gradually guided and moved in the center, forcing the material to remain stable and automatically correct its deviation during the conveying process.

[0032] See Figures 4-6 As shown, the pushing and limiting unit 4 includes a fixed mounting plate 41, a first support roller 42, a connecting plate 43, and a telescopic cylinder 44; the fixed mounting plates 41 are arranged in pairs and symmetrically on the housing 1; the first support roller 42 is rotatably arranged between the pair of fixed mounting plates 41; the connecting plates 43 are arranged in pairs and symmetrically on the housing 1, and the connecting plates 43 are close to one side of the fixed mounting plates 41; the telescopic cylinders 44 are arranged in pairs and symmetrically on the connecting plates 43.

[0033] The corrected material continues to be conveyed on the first support roller 42. The first support roller 42 is designed to maintain tension in the material during the conveying process, prevent the material from loosening or sagging, maintain the stability of the conveying, and thus enable the material to be corrected when it passes through the rotating clamping sleeve 33.

[0034] See Figure 5 As shown, the push limiting unit 4 also includes a push block 45, a push sleeve 46, and a contact block 47; the push block 45 is disposed at the output end of the telescopic cylinder 44; the push sleeve 46 is disposed on the push block 45, and there is a clearance fit between the push sleeve 46 and the first support roller 42; the contact block 47 is disposed on the push sleeve 46, and the contact block 47 is T-shaped.

[0035] When it is necessary to adjust the contact position between the rotating clamping sleeve 33 on the connecting plate 31 and the material, the telescopic cylinder 44 is first started and drives the push block 45 and the push sleeve rod 46 to move horizontally in a straight line along the first support roller 42 with clearance fit, until the push sleeve rod 46 drives the contact block 47 to limit the contact of the corrected material, and then the corrected material can be corrected a second time on the first support roller 42, ensuring the stability of the material conveying process.

[0036] See Figure 7 and Figure 8 As shown, the cleaning unit 5 includes a cleaning chamber plate 51, a pressure contact roller 52, and a cleaning roller 53; the cleaning chamber plate 51 is slidably disposed on the housing 1; the pressure contact roller 52 is a pair and is respectively disposed on the cleaning chamber plate 51; the cleaning chamber plate 51 is provided with a passage groove and a discharge groove for material to pass through; the cleaning roller 53 is rotatably disposed inside the cleaning chamber plate 51.

[0037] When the material passes over the first support roller 42, it continues to be conveyed through the through trough and discharge trough opened on the cleaning chamber plate 51. During this process, the material continues to be conveyed between a pair of pressure contact rollers 52. During this process, the cleaning roller 53 can come into contact with the material during the conveying process and effectively clean the dust and lint on the surface of the material.

[0038] See Figure 7 and Figure 8 As shown, the cleaning unit 5 also includes a suction pipe 54, a suction box 55, and a collection box 56; the suction pipe 54 has a pair and is symmetrically arranged on the cleaning chamber plate 51; the suction box 55 has a pair and is respectively arranged on the cleaning chamber plate 51; the collection box 56 is vertically slidably arranged inside the suction box 55.

[0039] The dust collection box 55 is equipped with an exhaust fan 551, and the collection box 56 is equipped with a filter screen 552 to prevent dust and lint from entering the exhaust fan 551. The filter screen 552 is fixedly connected to the collection box 56. By pulling the collection box 56, the dust and lint attached to the filter screen 552 can be emptied. This allows for the cleaning and collection of dust and lint on the surface of materials during material conveying, preventing dust and lint from adhering to the material.

[0040] Working principle: The first rotating roller 22 is responsible for feeding the material, while the second rotating roller 23 is responsible for discharging the processed material. The third rotating roller 24, located below the cleaning unit 5, primarily supports and presses against the cleaned material to ensure stable passage. The material sequentially passes through the first rotating roller 22, the anti-deviation unit 3, the push-limiting unit 4, the cleaning unit 5, the third rotating roller 24, and the second rotating roller 23, completing the anti-deviation and cleaning tasks throughout the entire conveying process. On the first rotating roller 22, the material begins to be conveyed and passes through the anti-deviation unit 3. This unit uses multiple rotating abutment sleeves 33 mounted on the bearing rotating rod 32. These sleeves are arranged sequentially from bottom to top, relatively close to each other. When the material contacts the rotating abutment sleeve 33, the sleeve gradually guides the material to move in the center, achieving automatic deviation correction and ensuring the stability of the material conveying. The corrected material continues to be conveyed on the first support roller 42, which helps maintain tension in the material and prevents slack or sagging. When it is necessary to adjust the contact position between the rotating clamping sleeve 33 and the material, the telescopic cylinder 44 drives the push block 45 and the push sleeve rod 46 to move horizontally. The material is then clamped and limited by the contact block 47, achieving secondary correction and ensuring stable material conveying. The material continues to be conveyed to the cleaning unit 5, passing through the through groove and discharge groove on the cleaning chamber plate 51, and is positioned between a pair of pressure-bearing contact rollers 52. The cleaning rollers 53 contact the material, effectively cleaning dust and lint from its surface. The exhaust fan 551 inside the dust collection box 55 operates, sucking dust and lint into the collection box 56. The filter screen 552 prevents these impurities from entering the exhaust fan 551, keeping the system clean. The filter screen 552 is easily cleaned by pulling the collection box 56.

[0041] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
