Description

Technical Field

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

[0002] The rubber roller is mainly composed of a roller shaft, a rubber layer and other structures, among which the roller shaft plays the role of support and transmission, and is the heaviest component in the rubber roller. Since the rubber roller is in a rotating state when working, in order to ensure the smooth operation of the equipment, after the roller shaft is processed, it is necessary to perform dynamic balancing detection on a special dynamic balancing detection device. For example, Chinese patent application No. 202223527059.5 discloses a roller dynamic balancing detection device, including a base, two movable wheels are installed on the left and right parts of the lower end of the base, a connecting shaft is installed between the two movable wheels on the right part, a driving device is installed on the outer surface of the connecting shaft, a support frame is installed on the right part of the upper end of the base, a detection device is installed on the upper right part of the support frame, a support seat is installed on the middle part of the upper end of the base, a support plate is installed on the left part of the upper end of the base, and an adjustment clamping device is installed on the right end of the support plate and the front inner wall and rear inner wall of the support seat. After the existing detection equipment detects the dynamic balance through sensors such as infrared sensors, it will give the angle of weight offset and the runout weight. According to the above parameters, the workers use tools such as chalk and protractor to draw the positions where holes need to be drilled on the side of the roller, and then drill holes on the side of the roller through a drilling rig to achieve the purpose of weight reduction, thereby adjusting the dynamic balance center of the roller so that the dynamic balance center of the roller is located on the central axis of the roller. However, the use of tools such as chalk and protractor is cumbersome. Many workers draw lines based on experience, resulting in poor hole positions and increased hole turning times. Therefore, a roller detection device is needed, which has a laser marker on one side to facilitate operators to quickly draw the positions of holes on the side of the roller and increase the speed of dynamic balance adjustment.

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.

If the specific posture changes, the directional indication will also change accordingly.

[0018] 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.

[0019] like Figures 1 to 3As shown, an embodiment of the utility model provides a roller detection device, including: a base 1, a first support 2, a second support 3, a side support frame 4, and a roller 5. The first support 2 and the second support 3 are installed on both sides of the base 1, and rollers 7 are provided on the upper parts of the first support 2 and the second support 3. Both ends of the roller 5 are mounted on the rollers 7; the side support frames 4 are installed on both sides of the base 1, and side top cones 8 are installed on the side support frames 4. One end of the side top cone 8 is slidably installed on the side support frame 4, and the other end of the side top cone 8 is inserted into the center hole on the side of the roller 5; the side top cone 8 is provided with a laser marker 6, and the laser marker 6 is rotatably connected to the side top cone 8, and the laser rays emitted by the laser marker 6 are irradiated on the side of the roller 5.

[0020] The roller 5 is placed on the first support 2 and the second support 3, and then a thrust is applied to the side top cone 8 through the side support frame 4, so that the roller 5 can be prevented from axial deviation during dynamic balancing adjustment. The roller 5 rotates under the drive of the driving device and the belt, and the angle of the center of gravity relative to the 0° position and the weight of the deviation are detected by the sensor. After the roller 5 stops, the operator rotates the first rotating rod 11 so that the laser emitted by the laser marker 6 on the first rotating rod 11 is irradiated at the 0° position, and then the second sleeve 13 is fixed by the locking nut on the second sleeve 13, and then the second rotating rod 12 is rotated so that the pointer on the identification hole 16 points to the corresponding scale. At this time, the second rotating rod 12 is rotated to prevent the roller 5 from axial deviation during dynamic balancing adjustment. The laser line marker 6 on the second rotating rod 12 emits a laser beam that shines on the side of the roller 5. The beam is the offset direction of the center of gravity of the roller 5. After the operator marks the roller 5 with chalk, he uses a drill to drill holes on the marking line to reduce the weight of the offset side. The offset weight can be adjusted by the drilling depth, so that the center of gravity is corrected back to the central axis of the roller 5. The first rotating rod 11 and the second rotating rod 12 can rotate freely on the first sleeve 10 to meet the requirements of marking at different angles. The laser line marker 6 adopts a currently commercially available laser line marker that emits a straight line of laser that shines on the side and periphery of the roller 5 to facilitate operator marking.

[0021] In a preferred embodiment, Figure 2 , Figure 3 As shown, a slider 9 is provided in the side support frame 4, and the slider 9 is slidably connected to the side support frame 4, and one side of the slider 9 is connected to the side support frame 4 through a locking nut 14, and a first sleeve 10 is provided on the other side of the slider 9. The interior of the first sleeve 10 is connected to the side top cone 8 through a bearing. The slider 9 can slide up and down to meet the marking of rollers of different diameters, and the side top cone 8 can rotate in the first sleeve 10, so as to apply thrust to the side of the roller shaft 5 through the side top cone 8 to prevent axial displacement of the roller shaft 5.

[0022] Specifically, Figure 2As shown, a first rotating rod 11 and a second rotating rod 12 are provided on the side top cone 8. The first rotating rod 11 is connected to the first sleeve 10 through a second sleeve 13. The first rotating rod 11 can rotate circumferentially around the first sleeve 10. The end of the second rotating rod 12 is sleeved on the outside of the second sleeve 13. The length of the first rotating rod 11 is longer than that of the second rotating rod 12. The laser marker 6 is respectively installed at the ends of the first rotating rod 11 and the second rotating rod 12. The laser markers 6 on the two rotating rods can rotate freely without interfering with each other, so that the convenient direction of the center of gravity of the roller shaft 5 can be quickly marked by irradiating the laser marker 6 at the 0° position and the offset position.

[0023] Preferably, if Figure 2 As shown, a dial 15 is provided on the first rotating rod 11, and angle scale lines are provided on the outer side of the dial 15 to facilitate angle marking.

[0024] In a preferred embodiment, Figure 2 As shown, an identification hole 16 is provided in the middle of the second rotating rod 12, and a pointer is provided in the identification hole 16, and the pointer is located in the middle of the second rotating rod 12. The operator can quickly obtain the angle of the second rotating rod 12 relative to the first rotating rod 11 through the pointer on the identification hole 16, so as to quickly and accurately identify the direction of the center of gravity offset of the roller shaft 5.

[0025] Specifically, rollers 7 of the same size are symmetrically provided on the first support 2 and the second support 3, and the center plane of the side support frame 4 coincides with the symmetry plane of the roller 7. When rollers 5 of different diameters are placed thereon, their midlines will be on the symmetry plane. The center plane of the side support frame 4 coincides with the symmetry plane of the roller 7, so that after the slider 9 and the side top cone 8 slide up and down, they can be inserted into the center holes of rollers 5 of different diameters, thereby allowing the first rotating rod 11 and the second rotating rod 12 to rotate around the axis of the roller 5, which is convenient for quick line drawing.

[0026] 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.
