Description

Technical Field

[0001] The present application relates to the technical field of rubber roller production equipment, and in particular to a rubber coating thickness detection device. Background Art

[0002] During the production of rubber rollers, after the outer surface of the roller is roughened, it enters the rubber coating stage. The main function is to wrap the rubber strip around the outside of the roller so that the rubber layer can be tightly wrapped around the outside of the roller after later vulcanization. In the rubber coating process, the tape is currently wrapped around the outside of the roller layer by layer. After the rubber layer thickness of the entire rubber roller reaches the set thickness, it can enter the later vulcanization process. Currently, there are two types of rubber coating thickness detection: contact and non-contact. For some smaller rubber rollers, the outer diameter of the rubber roller can be measured by a vernier caliper or the like. The thickness of the rubber layer can be obtained by subtracting the outer diameter of the roller and dividing by 2. For rubber rollers with larger diameters, non-contact measurement is mostly used. The distance difference before and after the rubber roller is coated with rubber is detected by laser or ultrasonic ranging. The difference is the thickness of the rubber layer. For example, a method for detecting the thickness of the rubber layer is disclosed in Chinese patent application number 202022457797.1. The rubber coating device comprises a mounting mechanism, a tape roller shaft and a tape stabilizing mechanism. A thickness gauge is arranged on the tape stabilizing mechanism. The thickness gauge is aligned with the part to be rubber coated to detect the thickness of the rubber coating. In actual use of the equipment, the outer diameter of the rubber roller has various specifications ranging from 20 cm to 100 cm, and the outer diameter varies greatly. Moreover, the thickness gauge is fixed on the equipment. At present, industrial laser rangefinders have long range or high precision due to the different laser wavelengths used. Although the long-range laser rangefinder has a sufficient range, the accuracy is only ±1 mm, which cannot meet the requirements. The high-precision laser rangefinder has an accuracy of ±0.05 mm, but the optimal range is only 20 cm to 30 cm, which cannot meet the manufacturing of rubber rollers of different specifications. Therefore, a rubber coating thickness detection device is required, and the laser rangefinder configured therein can adjust the position on the equipment to meet the production requirements of rubber rollers of different outer diameter specifications. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a rubber coating thickness detection device, which is equipped with a laser rangefinder that can adjust the position on the equipment to meet the production requirements of rubber rollers with different outer diameter specifications.

[0004] This application is implemented through the following technical solutions:

[0005] The present application proposes a rubber bag thickness detection device, comprising: a rubber wrapping machine platform, a walking machine platform, a distance meter bracket, and a distance meter. A roller is installed on the rubber wrapping machine platform, a guide rail is provided on the ground on one side of the rubber wrapping machine platform, and the walking machine platform is installed on the guide rail. The distance meter bracket comprises an outer cylinder and a slide rod, one end of the outer cylinder is installed on the upper part of the walking machine platform through a rotating shaft, one end of the slide rod is inserted into the outer cylinder and slidably connected to the outer cylinder, and the other end of the slide rod is fixedly connected to the distance meter, and the detection end of the distance meter faces the roller.

[0006] Furthermore, a locking nut is provided on the outer cylinder, and one end of the locking nut passes through the outer cylinder along the radial direction of the outer cylinder and is tightly pressed on the sliding rod.

[0007] Furthermore, a connecting block is provided on the upper part of the walking machine platform, one side of the connecting block is hinged to the walking machine platform through a rotating shaft, and the connecting block is connected to the middle part of the outer cylinder through a pull rod.

[0008] Furthermore, the lower end of the pull rod is hinged to the middle part of the outer tube, the upper end of the pull rod passes through the connecting block, and an adjusting nut is installed on the upper end of the pull rod.

[0009] Furthermore, an air blowing pipe is installed on the walking machine, the air blowing pipe is installed on the rangefinder bracket, one end of the air blowing pipe faces the detection end of the rangefinder, and the other end of the air blowing pipe is connected to the high-pressure air source through a joint.

[0010] Furthermore, the guide rail is parallel to the roller shaft, and the swing plane of the rangefinder bracket is perpendicular to the axis of the roller shaft.

[0011] The beneficial effects of the present application are as follows: by using a distance meter bracket to fix the distance meter, the distance between the distance meter and the roller can be appropriately adjusted according to the outer diameter of the roller to be processed, so that the distance between the distance meter and the roller is within the measuring range, so as to adapt to rollers with different outer diameters.

[0015] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0017] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0018] like Figure 1 to Figure 2 As shown, an embodiment of the utility model provides a device for detecting the thickness of a rubber bag, comprising: a wrapping machine platform 1, a walking machine platform 2, a rangefinder bracket 3, and a rangefinder 4. A roller 5 is installed on the wrapping machine platform 1, a guide rail 6 is provided on the ground on one side of the wrapping machine platform 1, and the walking machine platform 2 is installed on the guide rail 6. The rangefinder bracket 3 comprises an outer cylinder 7 and a slide bar 8. One end of the outer cylinder 7 is installed on the upper part of the walking machine platform 2 through a rotating shaft, one end of the slide bar 8 is inserted into the outer cylinder 7 and is slidably connected to the outer cylinder 7, and the other end of the slide bar 8 is fixedly connected to the rangefinder 4, and the detection end of the rangefinder 4 faces the roller 5.

[0019] Before rubberizing the roller 5, loosen the locking nut 9, then adjust the position of the distance meter 4 so that the interval between the distance meter 4 and the roller 5 is 30cm to 25cm, which meets the range requirement of the distance meter 4, and then tighten the locking nut 9 to prevent the slide bar 8 from sliding in the outer tube 7 during rubberizing. After the position of the distance meter 4 is adjusted, adjust the adjusting nut 12 to make the distance meter bracket 3 swing, and then adjust the direction of the distance meter bracket 3. When the reading of the distance meter 4 is the smallest, it means that the distance between the distance meter 4 and the roller 5 is the shortest. At this time, the distance meter bracket 3 points to the center of the roller 5. After completing the above adjustment, the distance is cleared on the indicator of the distance meter 4.

[0020] When the roller 5 is coated with rubber, the tape roll is installed on the support frame on the walking machine 2, and then the tape is pulled through the pressure roller to be wound on the roller 5. The roller 5 is driven to rotate by the rotating mechanism on the wrapping machine 1, and the motor on the walking machine 2 drives the walking machine 2 to move back and forth along the guide rail 6, so that the tape is evenly wound on the roller 5. When wrapping the tape, the distance between the roller 5 and the distance meter 4 is detected in real time by the distance meter 4. Since the indication of the distance meter 4 has been cleared before the rubber coating, the indicator of the distance meter 4 is the change value before and after the rubber coating, and the change value is the thickness of the rubber layer on the roller 5. However, when the thickness of the rubber layer reaches the process requirements, the winding is stopped, and after processing, it can be sent to the vulcanization tank for vulcanization.

[0021] The distance meter 4 adopts the currently available high-precision laser distance meter, with the accuracy of ±0.05mm and the maximum range of 400mm. For rollers 5 of different diameters, the distance of the distance meter 4 from the outer periphery of the roller 5 can be adjusted by the distance meter bracket 3 to adapt to rubber rollers of different diameters, and the distance meter bracket 3 can be swung to make the detection end of the distance meter 4 point to the center of the roller 5, so as to obtain the thickness of the rubber bag through the change of the indication before and after the rubber bag.

[0022] In a specific embodiment, a locking nut 9 is provided on the outer cylinder 7, and one end of the locking nut 9 passes through the outer cylinder 7 along the radial direction of the outer cylinder 7 and is tightly pressed on the slide rod 8. After the locking nut 9 is tightened, the slide rod 8 can be clamped to prevent the slide rod 8 from sliding in the outer cylinder 7 when the equipment is running, thereby affecting the detection result.

[0023] Specifically, a connecting block 10 is provided on the upper part of the walking machine 2, and one side of the connecting block 10 is hinged to the walking machine 2 through a rotating shaft, so that the connecting block 10 can rotate within a certain angle range to adapt to the angle change of the pull rod 11. The connecting block 10 is connected to the middle part of the outer cylinder 7 through the pull rod 11, and the pull rod 11 can drive the outer cylinder 7 to adjust the pitch angle, adjust the angle of the rangefinder 4, so that the laser emitted by the rangefinder 4 can point to the axis of the roller 5, so that the rangefinder 4 can accurately convert the rubber coating thickness of the roller 5 through the distance change.

[0024] In a specific embodiment, Figure 2 As shown, the lower end of the pull rod 11 is hinged to the middle of the outer tube 7, the upper end of the pull rod 11 passes through the connecting block 10, and an adjusting nut 12 is installed on the upper end of the pull rod 11. After the adjusting nut 12 is rotated, the pull rod 11 can be driven to move axially through the thread, thereby driving the rangefinder bracket 3 to perform pitch adjustment.

[0025] In a preferred embodiment, an air blowing pipe 13 is installed on the walking machine 2, and the air blowing pipe 13 is installed on the rangefinder bracket 3, and one end of the air blowing pipe 13 is facing the detection end of the rangefinder 4, and the other end of the air blowing pipe 13 is connected to the high-pressure air source through a joint. Since there is some dust in the workshop and the rangefinder 4 is close to the rotating roller 5 and is easily affected by the thrown adhesion promoter, the air blowing pipe 13 is used to regularly blow air to the glass of the detection end of the rangefinder 4 to ensure the cleanliness of the detection end of the rangefinder 4.

[0026] Preferably, if Figure 1 As shown, the guide rail 6 is parallel to the roller 5, so that when the walking machine 2 moves, the distance between the rangefinder 4 and the roller 5 remains unchanged, and the swing plane of the rangefinder bracket 3 is perpendicular to the axis of the roller 5. After the rangefinder bracket 3 is adjusted by adjusting the nut 12 and the pull rod 11, the laser emitted by the rangefinder 4 can be radially emitted to the center of the roller 5. The thickness of the rubber coating on the roller 5 can be obtained by the change in the distance before and after the rubber coating, thereby realizing contactless distance measurement.

[0027] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
