Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a roller device for avoiding the generation of paper scraps. Background Technology

[0002] In existing aseptic packaging production lines, packaging materials are usually guided and transported by steering rollers. Most existing rollers have a fully cylindrical structure, and their roller surfaces are in contact with the entire width of the packaging material. However, paper scraps are easily left behind at the edges of the packaging material during the cutting and forming process. These paper scraps will further fall off and accumulate when they come into contact with and rub against the roller surface, resulting in paper scraps contaminating the aseptic system such as the aseptic silo and affecting the cleanliness of the production environment. Therefore, it is necessary to solve the problem that the existing roller structure is prone to generating paper scraps by rubbing against the edges of the packaging material, causing contamination of the aseptic system. Utility Model Content

[0019] Please refer to Figure 1This utility model provides a roller device to avoid paper scraps, comprising: a roller body 100 and a paper piece, wherein the roller body 100 includes a rotating roller 101 and a covering layer 102 disposed on the outer wall of the rotating roller 101; the width of the paper piece is greater than the length of the covering layer 102; when the paper piece is transported through the roller body 100, the middle part of the paper piece contacts the covering layer 102, and the opposite sides of the paper piece are suspended. Further, the roller body 100 includes a rotating roller 101 and a covering layer 102 disposed on the outer wall of the rotating roller 101, specifically a metal roller can be used as the rotating roller 101 with a rubber layer wrapped around its surface. The width of the paper piece is greater than the length of the covering layer 102, specifically a covering material width that is at least 10 mm longer than the covering layer 102, and the suspension of the paper piece on both sides avoids contact and friction between the edges and the roller. When a sheet of paper is transported through the roller body 100, the middle of the sheet contacts the covering layer 102, while the opposite sides of the sheet are suspended. This prevents the edges of the sheet from contacting the roller surface, thus avoiding edge friction and paper scraps. The roller body 100 rotates to drive the sheet, and the covering layer 102 provides appropriate friction to ensure stable transport of the sheet. The contact area between the middle of the sheet and the covering layer 102 is sufficient to support the weight of the sheet and provide transport power, while the suspended edges effectively prevent paper scraps from forming.

[0020] In this embodiment, the width of the paper piece is 10 mm greater than the length of the covering layer 102, and the distance between the two sides of the paper piece and the covering layer 102 is 5 mm. Further, the length of the covering layer 102 is 10 mm less than the width of the paper piece, forming a 5 mm gap on each side. This dimensional relationship ensures that the length of the suspended portion is limited within a specific range by maintaining a fixed distance between the two ends of the covering layer 102 and the edge of the paper. The friction generated when the rubber covering layer 102 contacts the center of the paper effectively suppresses lateral paper shift, while the symmetrical distribution of the gaps on both sides maintains the force balance of the paper during transport.

[0021] In this embodiment, the covering layer 102 is made of rubber material. Furthermore, the rubber material has elastic deformation capability, which reduces friction with the paper through its own deformation. The covering layer 102 is fixedly connected to the outer wall of the rotating roller 101 to ensure stability during rotation. Specifically, when the paper is transported through the roller body 100, the rubber covering layer 102 contacts the center of the paper, using the elastic deformation of the rubber to absorb contact stress, reduce the coefficient of friction, and reduce paper scraps. The rubber material rotates with the rotating roller 101, forming a buffer interface between its surface and the paper, avoiding edge wear caused by hard contact.

[0022] In this embodiment, the roller body 100 includes a connecting shaft 103 integrally formed with both sides of the rotating roller 101. The connecting shaft 103 and the bearing housing 104 are connected. The bearing housing 104 is provided with a bearing whose inner ring is connected to the connecting shaft 103. Furthermore, the connecting shaft 103 is formed on both sides of the rotating roller 101 through an integral forming process, eliminating the assembly gap that may be generated by the split connection. The connecting shaft 103 is embedded in the bearing inner ring in the bearing housing 104, and the rotational support is achieved through the fixed cooperation between the bearing inner ring and the connecting shaft 103. The bearing housing 104 serves as a load-bearing structure, restricting the rotational movement of the rotating roller 101 within the axial range.

[0023] In this embodiment, a drive motor 200 is included. One end of the connecting shaft 103 is connected to the drive end of the drive motor 200. Further, the drive motor 200 is fixedly connected to one end of the connecting shaft 103 via a coupling or a transmission belt, and the drive end outputs rotational power. The other end of the connecting shaft 103 is fixed to the inner ring of the bearing in the bearing housing 104. Specifically, after the drive motor 200 starts, the rotational torque output from the drive end is transmitted to the rotating drum 101 through the connecting shaft 103, causing the covering layer 102 to rotate synchronously. The contact area between the middle of the paper and the covering layer 102 moves with the direction of drum rotation under the action of friction, while the suspended areas on both sides avoid paper scraps falling off due to the lack of contact friction. The constant speed control of the drive motor 200 ensures uniform paper transport speed and reduces sliding friction between the covering layer 102 and the paper caused by speed fluctuations.

[0024] In this embodiment, the roller body 100 includes at least an active roller 300, a first passive roller 310, and a second passive roller 320. The active roller 300 is disposed between the first passive roller 310 and the second passive roller 320. The active roller 300 is connected to the drive end of the drive motor 200. Further, the active roller 300 is configured as the power output core. The drive end of the drive motor 200 is rigidly connected to the connecting shaft 103 of the active roller 300 through a coupling or gear set. The covering layer 102 forms a continuous contact surface on the surfaces of the three rollers. During the transmission process, the paper passes through the first passive roller 310, the active roller 300, and the second passive roller 320 in sequence.

[0025] Specifically, after the drive motor 200 starts, the power drives the active roller 300 to rotate via the connecting shaft 103. The first passive roller 310 and the second passive roller 320 rotate passively under the influence of the paper. The central region of the paper comes into contact with the covering layer 102 of the active roller 300.

[0026] In this embodiment, a housing 400 is included, within which a receiving space 401 is provided. The roller body 100 is disposed within the receiving space 401. The housing 400 isolates the roller body 100 from the external environment through the receiving space 401, forming a physical barrier. Furthermore, a collection device can be provided below the roller, allowing paper scraps to fall into it. This effectively blocks the path of paper scrap diffusion, preventing paper scraps from entering the sterile chamber 500 or the hydrogen peroxide tank.

[0027] In this embodiment, a window is provided on the top of the housing 400, and the window is covered by a movable cover plate 402, which is rotatably connected to the window. Furthermore, the window is located in the central area of ​​the top of the housing 400, and its size covers the mounting area of ​​the roller body 100. The movable cover plate 402 is made of metal sheet, and one edge of it is rotatably connected to the edge of the window via a hinge. When closed, the cover plate is flush with the top plane of the housing 400, and the opening angle range of the cover plate is 0-90 degrees. A sealing strip is provided on the inner edge of the cover plate, forming a compression seal with the edge of the window when closed. Furthermore, a handle 403 is provided on the top of the movable cover plate 402 for convenient gripping and rotating the cover plate 402.

[0028] In this embodiment, the bearing housing 104 is disposed on the inner sidewall of the housing 400. The bearing housing 104 is fixed to the inner sidewall of the housing 400 by welding or bolting. The fixing position is selected in the inner sidewall area symmetrically distributed on both sides of the housing 400, and is located within the axial projection range corresponding to the end of the connecting shaft 103. The outer ring of the bearing is fixed in the bearing housing 104 by interference fit or snap-fit ​​structure, and the inner ring of the bearing is clearance fitted to the connecting shaft 103 and injected with grease.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
