Description

Technical Field

[0001] This utility model relates to the technical field of packaging bag production equipment, specifically to a wrinkle-resistant flattening roller based on image recognition. Background Technology

[0002] Thin sheet materials, such as packaging bags, printed materials, and paper, are typically processed through multiple steps by being conveyed forward by several conveyor rollers during the production process. Due to different uses, the extensibility of thin sheet materials varies in different areas.

[0003] In production practice, taking packaging bags as an example, common packaging bags include polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). Depending on the purpose, different areas of a plastic packaging bag can have different extensibility, such as different extensibility resulting from different thicknesses on the front and back, or different extensibility caused by different materials in different areas;

[0004] In existing technology, packaging materials in a flattened state are conveyed forward by several conveying rollers, and then sealed by equipment to obtain semi-finished or finished packaging bags. In production practice, due to the different extensibility of different areas of the flattened packaging material, and in order to ensure the needs of online image recognition and detection during the conveying process, the flattened packaging material must also be tensioned, which causes the packaging material to wrinkle easily during forward conveying, seriously affecting the accuracy of online image recognition and detection. Utility Model Content

[0005] This utility model discloses a wrinkle-resistant flattening roller based on image recognition. It solves the technical problem in existing technologies where wrinkles occur due to varying extensibility in different areas of the conveyed thin, sheet-like material, affecting production stability and hindering the improvement of finished product quality. The roller has a reasonable structure, provides good support during transport, and reduces the likelihood of wrinkles. The technical solution adopted is as follows:

[0006] A wrinkle-resistant flattening roller based on image recognition includes a roller body that can abut against, tension, and convey material. The roller body is designed such that its axis is inclined and forms a lower end and a higher end, or the roller surface of the roller body includes outwardly bulging portions to tension the material.

[0007] Based on the above technical solution, when the axis of the roller body is tilted to form a lower end and a higher end, an adjustment component is also included. The adjustment component is designed to make the vertical height position of the lower end or the higher end of the roller body adjustable.

[0008] Based on the above technical solution, the adjustment component includes a screw and a nut sleeved on the screw. When the nut moves up and down relative to the screw, the lower end or the higher end of the roller body moves accordingly, so that the upper and lower height positions of the lower end or the higher end of the roller body are adjustable.

[0009] Based on the above technical solution, the axis of the roller body is set horizontally, and the bulge is a conical section coaxial with the roller surface.

[0010] Based on the above technical solution, the small-diameter end of the conical section smoothly transitions to the adjacent roller surface, or the conical section covers the roller surface axially.

[0011] Based on the above technical solution, the axis of the roller body is set horizontally, and the bulge is a drum section coaxial with the roller surface.

[0012] Based on the above technical solution, the drum surface section smoothly transitions with the adjacent roller surface, or the drum surface section covers the roller surface axially.

[0013] Based on the above technical solution, the roller surface of the roller body is integrally formed.

[0014] Beneficial effects

[0015] This utility model has a reasonable structure. The roller body is designed such that the axis of the roller body is inclined and forms a lower end and a higher end, or the roller body includes a bulge. In this way, it can adaptively support areas with different extensibility on thin sheet materials, that is, always keep each area of ​​the material in a taut state, reduce the probability of wrinkles, ensure printing and dyeing quality, ensure good accuracy of online image recognition and detection, and help improve the quality of finished products.

[0016] When the roller body axis is tilted to form a lower end and a higher end, an adjustment component is also included, which can adjust the degree of tilt of the roller body axis to adapt to different material conveying.

[0017] When the roller surface of the roller body includes an outwardly bulging portion, the bulging portion can be a conical section or a drum section to accommodate areas with different ductility on the material, provide good support for the material, and reduce the probability of wrinkles.

[0018] This invention is ingeniously designed. The roller body axis is inclined or the roller surface includes a bulge. This not only provides good support for the material, but also allows the slightly deformed material to be displaced relative to the roller body due to the different radial dimensions of the contact surface between the roller body and the material relative to the transmission plane, further reducing the probability of wrinkles.

[0019] In this invention, when the bulging part is a drum-shaped section, during the transmission process, the centerline of the material can be automatically aligned with the centerline of the drum-shaped section, which helps to ensure the stability of the transmission process.

[0031] Example 1

[0032] like Figures 1-3 The image recognition-based anti-wrinkle flattening roller shown includes a roller body 1, which can come into contact with the material, tension and convey the material.

[0033] The roller body 1 is designed such that its axis is inclined in the vertical plane and forms a lower end and a higher end. In this embodiment, the roller body 1 is a passive roller, and the roller surface 12 of the roller body 1 can rotate relative to the roller shaft 11. To facilitate the adjustment of the axis of the roller body 1, the frame side plate 3 corresponding to the positions at both ends of the roller shaft 11 is provided with vertically extending elongated holes 31. The two ends of the roller shaft 11 pass through the two elongated holes 31 respectively. The first end 111 of the roller shaft 11 passes through the elongated hole 31 and is hinged to the first mounting plate on the frame side plate 3.

[0034] like Figure 2 and 3As shown, it also includes an adjustment component 2, which is located near the second end of the roller shaft 11. In this embodiment, the adjustment component 2 includes a screw 21, a nut 22 sleeved on the screw 21, a fixing seat 23, and a pin 24. The screw 21 passes through two vertically arranged second mounting plates 4 and is screwed to the two second mounting plates 4. The two second mounting plates 4 are fixed on the side plate 3 of the frame. The nut 22 is located on the screw 21 between the two second mounting plates 4. The fixing seat 23 is sleeved on the outside of the nut 22 and fixedly connected to the nut 22. The fixing seat 23 abuts laterally against the outer wall of the side plate 3 of the frame. When the screw 21 is rotated, the nut 22 and the fixing seat 23 can be moved up and down. The second end 112 of the roller shaft 11 passes through the elongated hole 31 at the corresponding position and extends into the fixing seat 23. Figure 3 As shown, the second end 112 of the roller shaft 11 is provided with an axially extending positioning elongated hole. The first end of the pin shaft 24 is fixedly connected to the fixed seat 23, and the second end of the pin shaft 23 passes through the positioning elongated hole. In this way, the higher end of the roller body 1 moves with the pin shaft 23, and the vertical height position of the higher end of the roller body 1 is adjustable.

[0035] Thus, when different areas of the material have different extensibility and the tensioning process causes uneven material stretching, the material can be well tensioned and supported by adaptively adjusting the height of the higher end of the roller body, while flattening the material to avoid wrinkles and facilitating image recognition.

[0036] In other embodiments of this utility model, the adjustment component 2 may also be located near the first end 111 of the roller 11.

[0037] Example 2

[0038] The difference between Example 2 and Example 1 is that, as Figure 4 As shown, the axis of the roller body 1 is set horizontally in the vertical plane, and the two ends of the roller shaft of the roller body 1 pass through the two frame side plates 3 and are connected to the frame side plates 3.

[0039] like Figure 4 As shown, the roller surface of the roller body 1 bulges outward to form a bulge portion, which is a drum section 13 coaxial with the roller surface. The drum section 13 smoothly transitions with the adjacent roller surface 12 and is integrally formed, which is beneficial for stably supporting and tensioning the material. The bulge portion is designed to correspond to the area of ​​the material with better extensibility, supporting the area of ​​the material with better extensibility to reduce the degree of wrinkling. In this embodiment, the drum section 13 has a left-right symmetrical structure to evenly support and flatten the material.

[0040] In other embodiments of this utility model, the drum section 13 covers the roller surface 12 along the axial direction, and correspondingly, the area with better extensibility on the material is roughly in the center and accounts for a large proportion of the area.

[0041] Example 3

[0042] The difference between Example 3 and Example 2 is that, as Figure 5 As shown, the axis of the roller body 1 is horizontally arranged, and the bulge is a conical section 14 coaxial with the roller surface 12. In this embodiment, the large-diameter section of the conical section 14 is flush with one end of the roller shaft 11, and the conical section 14 corresponds to the area on the material with better extensibility. The small-diameter end of the conical section 14 smoothly transitions to the adjacent roller surface 12. In other embodiments of this utility model, the conical section 14 may also cover the roller surface 12 axially.

[0043] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
