Description

Technical Field

[0001] This utility model relates to the field of bonding roller inspection technology, and in particular to a device for detecting the straightness and radial runout of bonding rollers. Background Technology

[0002] Laminating rollers are widely used components in industrial production, commonly used in material bonding processes to extrude and bond different materials together. Due to the complex manufacturing process and high requirements for laminating rollers, the pass rate has consistently been low. Therefore, the straightness and radial runout detection of laminating rollers have always been of paramount importance in the manufacturing process.

[0003] For heavy-duty bonding rollers with a length of 1100 mm-1600 mm, a diameter of 600 mm-850 mm, and a weight of 0.5 tons-1.5 tons, since there is currently no special device for detecting the straightness and radial runout of such heavy-duty bonding rollers, they can only be directly installed on the production equipment, and the straightness and radial runout errors of the heavy-duty bonding rollers can be judged by the quality of the produced products.

[0004] However, judging the straightness and radial runout error of heavy-duty bonding rollers based on the quality of trial products will result in a large number of defective products and waste of resources. At the same time, due to the large weight of heavy-duty bonding rollers, their installation and disassembly on production equipment are very time-consuming and labor-intensive, which not only leads to huge consumption of manpower, but also makes it difficult to improve inspection efficiency.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0034] Example:

[0035] The specific embodiments of this utility model are as follows: Figure 1 , 2As shown in Figures 7 and 8, a device for detecting the straightness and radial runout of a bonding roller includes a horizontally arranged rectangular base 1. A slider mounting rail 11 is horizontally arranged on the upper surface of the base 1. A fixed slider 12 is fixed at one end of the slider mounting rail 11, and a movable slider 13, opposite to the fixed slider 12, is slidably mounted at the other end. A slider driving assembly is provided on the base 1 to drive the movable slider 13 to translate along the slider mounting rail 11. Both the fixed slider 12 and the movable slider 13 have V-shaped irons 14 at their tops to support the ends of the bonding roller. Furthermore, a roller assembly for driving the bonding roller shaft is located on the side of one V-shaped iron 14 away from the other. A micrometer displacement sensor 7 is also mounted on one side of the base 1 via a three-dimensional position adjustment assembly, and the detection end of the micrometer displacement sensor 7 is in perpendicular contact with the outer wall of the bonding roller. In this embodiment, the micrometer displacement sensor 7 is vertically arranged, and its detection end is located at its lower end.

[0036] Before testing, the length of the roller section of the bonding roller to be tested is measured using a measuring tape. Then, the position of the movable slider 13 is adjusted using the slider drive assembly so that the distance between the V-shaped iron 14 on the movable slider 13 and the V-shaped iron 14 on the fixed slider 12 is greater than the length of the roller section by 50mm-100mm. Next, the bonding roller to be tested is hoisted between the two V-shaped iron 14s, and the roller shafts at both ends of the bonding roller are placed on the two V-shaped iron 14s respectively. Then, the three-dimensional position adjustment assembly is used to adjust the three-dimensional spatial position of the micrometer displacement sensor 7 so that the detection end of the micrometer displacement sensor 7 is in perpendicular contact with the center high point of the outer wall of the bonding roller, thus completing the pre-test preparation. During testing, the bonding roller shaft is driven to rotate by the roller rotation assembly, and the micrometer displacement sensor 7 can detect the radial runout of the bonding roller; based on this, the three-dimensional position adjustment assembly drives the micrometer displacement sensor 7 to translate along the axial direction of the bonding roller, which can detect the straightness of the bonding roller.

[0037] It should be noted that in order to accurately adjust the distance between the two V-shaped iron blocks 14, a distance detection photoelectric sensor 16 is installed on the side wall of one of the V-shaped iron blocks 14, and a signal baffle 15 that cooperates with the signal of the distance detection photoelectric sensor 16 is installed on the side wall of the other V-shaped iron block 14.

[0038] Therefore, this equipment can perform straightness and radial runout detection before the installation of heavy-duty bonding rollers. Compared to the existing method of directly installing the bonding rollers onto the production equipment and judging the straightness and radial runout errors of the heavy-duty bonding rollers by the quality of the produced products, this equipment can avoid the generation of a large number of defective products, thereby avoiding resource waste. Furthermore, the use of this equipment also avoids the process of repeatedly installing and disassembling bonding rollers on the production equipment, saving manpower and improving inspection efficiency.

[0039] Regarding the specific structure of the slider drive component, such as Figure 3As shown, the slider drive assembly includes a slider drive screw 21 horizontally disposed on the upper surface of the base 1 and parallel to the slider mounting rail 11. The slider drive screw 21 is threadedly connected to the bottom of the movable slider 13, and one end of the slider drive screw 21 is connected to a slider drive motor 2 that drives its shaft to rotate. The slider drive motor 2 is fixedly mounted on the side wall of the base 1 by a motor mounting bracket. By driving the slider drive screw 21 to rotate through the slider drive motor 2, the movable slider 13 can move along the extension direction of the slider mounting rail 11, thereby adjusting the position of the movable slider 13 and thus adjusting the distance between the two V-shaped blocks 14.

[0040] Regarding the specific structure of the roller assembly, such as Figure 4 As shown: The roller assembly includes an L-shaped plate 3, the vertical plate of which is vertically slidably connected to the side wall of the V-shaped iron 14. Two friction wheels 33, parallel to the radial cross-section of the bonding roller and capable of axial rotation, are provided on the upper part of the vertical plate of the L-shaped plate 3 on the side facing away from the V-shaped iron 14. The upper surfaces of both friction wheels 33 are in close contact with the end side wall of the bonding roller. A wheel drive motor 35 is also provided on the upper surface of the flat plate of the L-shaped plate 3, and the power output end of the wheel drive motor 35 is connected to the shaft of one of the friction wheels 33 via a transmission belt 34. Through the power transmission of the wheel drive motor 35 and the transmission belt 34, one of the friction wheels 33 can be driven to rotate actively. Combined with the close contact between the friction wheel 33 and the roller shaft of the bonding roller, the bonding roller shaft can be driven to rotate by friction transmission. At this time, the other friction wheel 33 acts as a driven wheel and rotates passively.

[0041] In this embodiment, to ensure that the upper surfaces of both friction wheels 33 are in tight contact with the sidewall of the laminating roller end, a fixing plate 38 is horizontally provided below the flat plate of the L-shaped plate 3 and is fixedly connected to the V-shaped iron 14. A spring 37 is vertically provided between the fixing plate 38 and the flat plate of the L-shaped plate 3, and both ends of the spring 37 are in tight contact with the fixing plate 38 and the flat plate of the L-shaped plate 3, respectively. At the same time, at least two mounting slots 31 are vertically provided on the vertical plate of the L-shaped plate 3, and mounting screws 32 are provided in the mounting slots 31 and threadedly connected to the V-shaped iron 14. Through the elastic force of the spring 37 and the vertical sliding installation of the L-shaped plate 3 on the V-shaped iron 14, the two friction wheels 33 are in a vertically floating state, thus ensuring tight contact with the sidewall of the laminating roller end, thereby realizing friction-driven laminating roller.

[0042] In addition, regarding the specific structure of the three-dimensional position adjustment component, such as Figure 5 , 6As shown: The three-dimensional position adjustment assembly includes a slide rail mounting base horizontally disposed on one side of the base 1. The slide rail mounting base is connected to the base 1 via fixing brackets 43 disposed at both ends. The upper surface of the slide rail mounting base has an axial slide rail 4 horizontally disposed along the axial direction of the bonding roller, and an axial moving seat 44 is slidably mounted on the axial slide rail 4. The upper surface of the axial moving seat 44 has a radial slide rail 5 horizontally disposed along the radial direction of the bonding roller, and a radial moving seat 53 is slidably mounted on the radial slide rail 5. Simultaneously, a column 6 is vertically disposed on the upper surface of the radial moving seat 53. A lifting slide rail 61 is vertically mounted on the column 6 near the bonding roller, and a lifting cantilever 64 is slidably mounted on the lifting slide rail 61. The lifting cantilever 64 is horizontally disposed and extends towards the bonding roller, and its free end is connected to a micrometer displacement sensor 7 via a mounting bracket 71. The mounting bracket 71 uses a rack product, specifically model 7121-0025 manufactured by Dashico.

[0043] By sliding the axial moving seat 44 on the axial slide rail 4, the position of the micrometer displacement sensor 7 can be adjusted in the axial direction of the bonding roller; by sliding the radial moving seat 53 on the radial slide rail 5, the position of the micrometer displacement sensor 7 can be adjusted in the radial direction of the bonding roller; by sliding the lifting cantilever 64 on the lifting slide rail 61, the position of the micrometer displacement sensor 7 can be adjusted in the vertical direction. Thus, the three-dimensional spatial position of the micrometer displacement sensor 7 can be adjusted by combining these three methods.

[0044] In this embodiment, in order to accurately adjust the micrometer displacement sensor 7 in the axial direction of the bonding roller, an axial screw 41 parallel to the axial slide rail 4 is horizontally provided on the upper surface of the slide rail mounting base. The axial screw 41 is threadedly connected to the bottom of the axial moving seat 44, and one end of the axial screw 41 is connected to the axial motor 42 fixed on the slide rail mounting base.

[0045] In order to accurately adjust the micrometer displacement sensor 7 in the radial direction of the bonding roller, a radial screw 51 parallel to the radial slide rail 5 is horizontally provided on the upper surface of the axial moving seat 44. The radial screw 51 is threadedly connected to the bottom of the radial moving seat 53, and one end of the radial screw 51 is connected to the radial motor 52 fixed on the axial moving seat 44.

[0046] In order to accurately adjust the micrometer displacement sensor 7 in the vertical direction, a lifting screw 62 is vertically installed on the side of the column 6 near the bonding roller. The lifting screw 62 is threadedly connected to the lifting cantilever 64, and a lifting motor 63 is provided at the top of the column 6 and is connected to the upper end of the lifting screw 62.

[0047] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
