Description

Technical Field

[0001] The utility model relates to the technical field of measuring instruments, in particular to a device for detecting the parallelism between two rollers. Background Art

[0002] With the continuous development of the new energy industry, the key equipment for electrode preparation in the battery production process, such as coating machines and roller presses, as well as equipment in the thin film production process of other industries, will use roller mechanisms of varying numbers, diameters, and spacings. The rollers between the unwinding shaft and the reeling shaft need to maintain a high degree of parallelism to ensure the stability of the foil and film during the tape feeding process. Especially when ensuring that the foil does not curl or solving the elongation problem, a greater tension is required. The parallelism between the rollers is required to be higher. Otherwise, not only will the foil easily deviate and be unevenly wound, but it will also be more likely to wrinkle and break due to the different tensile tension on both sides, resulting in production waste. Traditionally, the parallelism of two rollers is measured with a tape measure or caliper to measure the distance between the two ends of the two rollers. However, due to errors in the operator's technique, the measuring points at both ends are difficult to find accurately, resulting in large measurement errors and the accuracy of the parallelism of the two rollers cannot be guaranteed.

[0003] The patent with publication number CN218380716U in the prior art discloses a roller parallelism detection tool, including a horizontal measuring rod, a reference limit rod, a dial indicator and a dial indicator fixing assembly, the reference limit rod is vertically arranged at the bottom of one end of the horizontal measuring rod, and the dial indicator is movably mounted on the horizontal measuring rod through the dial indicator fixing assembly; the dial indicator fixing assembly includes a clamping seat, a dial indicator clamping rod and an adjusting nut, the clamping seat can be movably mounted on the horizontal measuring rod and fixed by a set screw, the dial indicator clamping rod vertically passes through the clamping seat, and the dial indicator is clamped at the bottom; the surface of the dial indicator clamping rod is provided with a thread, and a limit groove is provided along its length direction, a limit rib is provided in the through hole of the clamping seat, and the adjusting nut threadedly connected to the dial indicator clamping rod is rotatably riveted above the through hole.

[0004] The above-mentioned parallelism detection tooling can detect different roller diameters and roller spacings, but it still has the following technical defects: it adopts a single-rod structure, which is unstable to a certain extent, and the connecting rod will swing left and right during measurement, affecting the measurement accuracy. Utility Model Content

[0005] The utility model provides a device for detecting and adjusting the parallelism of two rollers, which solves the problem in the prior art that a connecting rod may swing left and right relative to the rollers, thereby affecting measurement accuracy.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A device for detecting and adjusting the parallelism of two rollers comprises a reference roller support and a measuring assembly, the reference roller support and the measuring assembly being connected via a length adjustment assembly. The reference roller support comprises a positioning plate, to which at least two guide rods are connected, arranged perpendicularly to the positioning plate; the guide rods are located in the same plane, with the plane of the guide rods being perpendicular to the direction of extension and retraction of the length adjustment assembly. When the detection and adjustment device is in use, the plane of the guide rods and the positioning plate contact and position the reference roller, effectively preventing the adjustment device from swinging relative to the reference roller. This ensures that the relative angle between the length adjustment assembly and the axis of the reference roller is fixed each time the detection and adjustment device is placed on the reference roller, thereby ensuring measurement accuracy.

[0008] The positioning plate is provided with a connecting block, the length adjustment component is connected to the connecting block, and the guide rod and the connecting block are located on both sides of the positioning plate to avoid interference between the length adjustment component and the guide rod, thereby ensuring the normal use of the detection and adjustment device.

[0009] The length adjustment assembly includes an intermediate conversion block, to which a first connecting rod and a second connecting rod are slidably connected. The first connecting rod is connected to the measuring assembly at its end, while the second connecting rod is connected to the reference roller support. The intermediate conversion block is provided with a locking member for securing the first and second connecting rods. The length adjustment assembly allows the spacing between the reference roller support and the measuring assembly to be adjusted, enabling the detection and adjustment device to be adapted for parallelism testing at various roller distances.

[0010] The intermediate transition block is provided with a first connecting hole and a second connecting hole, with the first connecting rod slidingly engaging with the first connecting hole and the second connecting rod slidingly engaging with the second connecting hole. The locking member is a locking bolt, which passes through the side wall of the first connecting hole and is pressed into engagement with the first connecting rod, while the locking bolt passes through the side wall of the second connecting hole and is pressed into engagement with the second connecting rod. The connecting rod slides within the connecting hole to change the relative position of the connecting rod and the intermediate transition block, thereby adjusting the spacing between the reference roller support seat and the measuring assembly. After the positions of the first and second connecting rods are adjusted, the locking bolts are tightened to secure the first and second connecting rods, ensuring the stability of the detection and adjustment device during use.

[0011] The first and second connecting rods are both provided with scales, which facilitate the user to check the relative positions of the first and second connecting rods, thereby facilitating the user to precisely control and adjust the spacing between the reference roller support seat and the measuring assembly.

[0012] The intermediate conversion block is connected to at least two first connecting rods and at least two second connecting rods, with the number of first connecting rods and second connecting rods being equal. Multiple sets of connecting rods are used to connect the reference roller support seat and the measuring assembly to enhance the overall stability of the detection and adjustment device.

[0013] The measuring assembly includes a dial indicator mounting base, to which at least two dial indicators are detachably connected. The dial indicator contacts extend through the mounting base, and a first connecting rod is connected to the mounting base. Simultaneous measurement using multiple dial indicators allows the parallelism of the roller to be adjusted by directly observing the movement of the indicator needles during testing. This avoids a seesaw effect during adjustment and eliminates the need for repeated point-finding and testing, making adjustment more convenient.

[0014] The dial indicator fixing seat is provided with a clamping groove, the dial indicator is arranged in the clamping groove, and the clamping groove is provided with a clamping bolt for clamping the dial indicator.

[0015] The lengths of the contacts of the dial indicators extending out of the dial indicator fixing seat are equal, which facilitates the parallelism judgment of the two rollers during parallelism detection. Specifically, when the readings of the dial indicators tend to be consistent, the two rollers tend to be parallel.

[0016] The dial indicator fixing base and the connecting block are both provided with bubble level gauges. The bubble level gauge on the connecting block is used to determine the level of the reference roller, and the bubble level gauge on the dial indicator fixing base is used to determine the level of the detection and adjustment device.

[0017] The beneficial effects of the utility model are: 1. When the detection and adjustment device is in use, the two surfaces of the guide rod and the positioning plate are in contact with the reference roller and positioned, which can effectively prevent the adjustment device from swinging relative to the reference roller, and ensure that the relative angle between the length adjustment component and the axis of the reference roller is fixed each time the detection and adjustment device is placed on the reference roller, thereby ensuring the accuracy of the measurement.

[0018] 2. The distance between the reference roller support seat and the measuring assembly can be adjusted through the length adjustment component, so that the detection and adjustment device can be suitable for parallelism detection of different roller distances.

[0019] 3. The length adjustment assembly uses multiple sets of connecting rods to connect the reference roller support seat and the measuring assembly to enhance the overall stability of the detection and adjustment device.

[0020] 4. The scale on the connecting rod makes it easy for users to check the relative positions of the first connecting rod and the second connecting rod, thereby making it easier for users to accurately control and adjust the distance between the reference roller support seat and the measuring assembly.

[0021] 5. The bubble level is convenient for checking the level of the detection and adjustment device itself and the reference roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] When the device is in use, the reference roller support seat is mounted on the reference roller 10, and the distance between the reference roller support seat and the measuring assembly is adjusted by the length adjustment assembly so that the measuring assembly can contact the roller to be measured 11, and the parallelism between the reference roller 10 and the roller to be measured 11 is measured by the measuring assembly.

[0030] Example 2, based on Example 1, provides a device for detecting and adjusting the parallelism of two rollers. The length adjustment assembly includes an intermediate conversion block 5, to which a first connecting rod 41 and a second connecting rod 42 are slidably connected. The end of the first connecting rod 41 is connected to the measuring assembly, and the second connecting rod 42 is connected to the reference roller support seat. The intermediate conversion block 5 is provided with a locking member for securing the first connecting rod 41 and the second connecting rod 42. Specifically, the second connecting rod 42 is slidably connected to the connecting block 9, which is provided with a sliding hole and a fixing bolt. The fixing bolt passes through the side wall of the sliding hole and is pressed into engagement with the second connecting rod 42. The length adjustment assembly can be used to adjust the distance between the reference roller support seat and the measuring assembly, making the detection and adjustment device suitable for parallelism detection of different roller spacings.

[0031] Furthermore, the intermediate conversion block 5 is provided with a first connecting hole and a second connecting hole, wherein the first connecting rod 41 is slidably engaged with the first connecting hole, and the second connecting rod 42 is slidably engaged with the second connecting hole; the locking member is a locking bolt, which passes through the side wall of the first connecting hole and is pressed and engaged with the first connecting rod 41, and the locking bolt passes through the side wall of the second connecting hole and is pressed and engaged with the second connecting rod 42. In this embodiment, the number of the first connecting rod 41 and the second connecting rod 42 is one, and the first connecting rod 41 and the second connecting rod 42 are arranged in parallel; the connecting rod slides in the connecting hole to change the relative position of the connecting rod and the intermediate conversion block 5, thereby adjusting the spacing between the reference roller support seat and the measuring assembly, and after the positions of the first connecting rod 41 and the second connecting rod 42 are adjusted, the locking bolts are tightened to fix the first connecting rod 41 and the second connecting rod 42 to ensure the stability of the detection and adjustment device during use.

[0032] Furthermore, a scale is provided on each of the first connecting rod 41 and the second connecting rod 42. The scale facilitates the user to check the relative position of the first connecting rod 41 and the second connecting rod 42, thereby facilitating the user to precisely control and adjust the spacing between the reference roller support seat and the measuring assembly.

[0033] Example 3 is different from Example 2 in that a device for detecting and adjusting the parallelism of two rollers is provided. Figure 1As shown, the intermediate conversion block 5 is connected to at least two first connecting rods 41 and at least two second connecting rods 42, with the number of first connecting rods 41 and second connecting rods 42 being equal. In this embodiment, the number of each of the first connecting rods 41 and second connecting rods 42 is two, and the two first connecting rods 41 and the two second connecting rods 42 are simultaneously connected to one intermediate conversion block 5. The first connecting rods 41 and the second connecting rods 42 form a frame structure, effectively ensuring the structural stability of the detection and adjustment device.

[0034] Example 4, based on Example 1, Example 2, or Example 3, provides a device for detecting and adjusting the parallelism of two rollers, wherein the measuring assembly includes a dial indicator holder 2, to which at least two dial indicators 1 are detachably connected, the contacts of the dial indicators 1 extending out of the dial indicator holder 2, and a first connecting rod 41 connected to the dial indicator holder 2. In this embodiment, there are two dial indicators 1, and the two dial indicators 1 are respectively disposed at both ends of the dial indicator holder 2. Measurements are performed simultaneously using the two dial indicators 1.

[0036] Furthermore, the length of the contacts of each dial gauge 1 extending out of the dial gauge fixing base 2 is equal, which facilitates the parallelism judgment of the two rollers during parallelism detection. Specifically, when the readings of each dial gauge 1 tend to be consistent, the two rollers tend to be parallel.

[0037] Furthermore, a bubble level 3 is provided on both the dial indicator fixing base 2 and the connecting block 9. The bubble level 3 on the connecting block 9 is used to determine the level of the reference roller 10, and the bubble level 3 on the dial indicator fixing base 2 is used to determine the level of the detection and adjustment device.

[0038] The use process of the detection and adjustment device is as follows:

[0039] When preparing for use, first install the dial indicator 1 on the dial indicator fixing seat 2, and ensure that the length of the dial indicator 1 extending out of the dial indicator fixing seat 2 remains consistent; loosen the locking bolts on the intermediate conversion block 5, slide the first connecting rod 41 and the second connecting rod 42 on the intermediate conversion block 5, and adjust the relative positions of the first connecting rod 41 and the second connecting rod 42 according to the scale so that the total length of the detection and adjustment device can be adapted to the spacing between the reference roller 10 and the roller to be measured 11. After the positions of the first connecting rod 41 and the second connecting rod 42 are adjusted, tighten the locking bolts on the intermediate conversion block 5 to fix it;

[0040] During use, the two guide rods 7 and the positioning plate 6 of the reference roller support seat are simultaneously tangent to the reference roller 10, and the entire device is mounted on the reference roller 10. Then the device is rotated longitudinally to make the measuring head of the dial indicator 1 contact with the surface of the roller to be measured 11, which is in a slightly top state. The device is continued to rotate to make the value of the dial indicator 1 tend to be stable. When the value of one of the dial indicators 1 stabilizes at the minimum value, check the numerical deviation of the two dial indicators 1. This deviation is the parallelism deviation value of the two rollers. Then, the corresponding roller shaft end of the dial indicator that has not yet stabilized to the minimum value can be adjusted in parallel. While keeping the detection device stationary, adjust the values ​​of the two dial indicators to be consistent to complete the parallelism adjustment of the two rollers.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
