Abstract
Description
Technical Field
[0001] The utility model relates to the field of rubber rollers, in particular to a rubber roller facilitating dynamic balance adjustment. Background Art
[0002] A rubber roller is a roller-shaped object covered or made of rubber material, with its diameter usually ranging from dozens of millimeters to one meter and its length ranging from dozens of centimeters to several meters. The specific dimensions are determined according to actual application requirements. It is usually used in various industries such as the printing industry, plastic processing industry, rubber processing industry, and conveying system.
[0003] Regarding the above related technologies, the inventor found that during the production of rubber rollers, the rubber in the internal mixer is wound around the roller surface. Due to reasons such as production process, uneven material quality, or blank defects, the rubber on the roller surface is usually uneven in mass distribution relative to the axis, resulting in an unbalance amount during use, which easily causes vibrations during the rotation of the roller and accelerates the wear between parts. Therefore, designing a rubber roller for adjusting dynamic balance has become an urgent goal in this industry. Summary of the Utility Model
[0004] The main technical problem to be solved by the utility model is to provide a rubber roller facilitating dynamic balance adjustment, reducing the phenomenon of uneven mass distribution on the roller surface and enabling the roller to achieve motion balance.
[0005] To solve the above technical problem, a technical solution adopted by the utility model is: providing a rubber roller facilitating dynamic balance adjustment, including: a cylinder body and end covers connected to both ends thereof, hollow roller shafts are respectively connected to opposite sides of the end covers, and an adjustable counterweight assembly is further provided inside the cylinder body;
[0006] The adjustable counterweight assembly includes a counterweight rod and symmetrically arranged rotation adjustment members. Adjustment rods are respectively connected between the rotation adjustment members and the counterweight rod. Activity openings are respectively formed at both ends of the counterweight rod, and the adjustment rods are respectively inserted through the corresponding activity openings. Limiting mechanisms for preventing the counterweight rod from sliding up and down are respectively provided at both ends of the counterweight rod;
[0007] The rotation adjustment member includes an annular limiting block embedded in one end of the end cover facing each other. A rotating rod is fixedly connected inside the annular limiting block. Countersunk holes one are respectively formed at opposite ends of the hollow roller shaft. One end of the rotating rod is fixedly connected to the adjustment rod, and the other end is threadedly connected with a locking nut, and the locking nut is in contact connection with the inner wall of the countersunk hole one.
[0008] By adopting the above technical solution, the rotating rod drives the adjusting rod and the counterweight rod to rotate under the action of the annular limiting block, so that it rotates to the surface of the cylinder with lower mass, and cooperates with the locking nut to tightly abut against the inner wall of the hollow roller shaft to prevent loosening. The locking nut firmly fixes the rotating rod on the hollow roller shaft through threaded connection, ensuring the stability and reliability of the counterweight assembly, and enabling the counterweight rod to move axially to move the adjusting rod. At the same time, the limiting mechanism is used to fix it, and the position change of the counterweight rod is used to change its center of gravity distribution, thereby compensating for the imbalance generated on the surface of the roller.
[0009] In a preferred embodiment of the present utility model, it can be further configured that: a number of first convex teeth are connected at intervals on the opposite side of the adjusting rod. The limiting mechanism includes a receiving groove opened on the side of the movable opening away from the first convex teeth. A driving block is installed in the receiving groove. A number of second convex teeth are connected at intervals on the side of the driving block close to the first convex teeth. A countersunk hole two is opened at one end of the counterweight rod. The countersunk hole two communicates with the receiving groove. An adjusting bolt whose driving second convex teeth mesh with the first convex teeth is threadedly connected in the countersunk hole two. One end of the adjusting bolt is rotatably connected to the driving block, and the driving block is always located in the receiving groove.
[0010] By adopting the above technical solution, the first convex teeth on the adjusting rod and the second convex teeth on the driving block are connected in a meshing manner, and the movement of the driving block is controlled by rotating the adjusting bolt, thereby driving the position adjustment of the counterweight rod on the adjusting rod and limiting it at a suitable position to prevent it from moving.
[0011] In a preferred embodiment of the present utility model, it can be further configured that: a number of fan-shaped openings are annularly arranged on the end cover.
[0012] By adopting the above technical solution, the fan-shaped openings can enable the operator to directly use a socket wrench or other standard tools to rotate the internal adjusting bolt through external operation, thereby adjusting the position of the counterweight rod, without disassembling the entire end cover or other parts of the roller, avoiding complex disassembly and reinstallation processes, and reducing the operation difficulty and time cost.
[0013] In a preferred embodiment of the present utility model, it can be further configured that: reinforcing ribs matching the number of the fan-shaped openings are connected to the end cover. One end of the reinforcing rib is connected to the cylinder body, and the other end is connected to the roller shaft.
[0014] By adopting the above technical solution, the reinforcing ribs are used to reduce the stress concentration phenomenon at the connection between the end cover and the cylinder body, disperse the stress and load generated during the operation of the roller, thereby improving the overall structural strength of the roller.
[0015] In a preferred embodiment of the present utility model, it can be further configured that: color scale marks are provided on the opposite side of the adjusting rod.
[0016] By adopting the above technical solution, color scale markings form an indication area on the adjusting rod through different colors or changes in color shades, enabling the operator to visually see the current position of the counterweight rod and make precise adjustments accordingly.
[0017] In summary, the present utility model includes at least one of the following beneficial technical effects of a rubber roller that facilitates dynamic balance adjustment:
[0018] 1. Under the action of the locking nut, the fixed connection between the rotating rod and the hollow roller shaft is achieved, and it also allows the position of the counterweight rod in the circumferential direction of the cylinder body to be adjusted by loosening the locking nut when needed. At the same time, it is fixed by cooperating with the limiting mechanism, and the center of gravity distribution is changed by the position change of the counterweight rod, thereby compensating for the imbalance generated on the surface of the roller.
[0019] 2. By combining the meshing mechanism of the first convex tooth and the second convex tooth, the threaded connection of the adjusting bolt, and the intuitive indication of the color scale marking, the operator only needs to rotate the adjusting bolt according to the guidance of the color scale marking to achieve precise adjustment of the position of the counterweight rod. This not only reduces the human judgment error but also greatly shortens the adjustment time and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Refer to Figures 1-3 , a rubber roller for facilitating the adjustment of dynamic balance disclosed by the present invention, comprising: a cylinder body 1 and end covers 2 connected to both ends thereof. A plurality of fan-shaped openings 5 are annularly arranged on the end covers 2. Hollow roller shafts 3 are respectively connected to the opposite sides of the end covers 2. An adjustable counterweight assembly 40 is further provided inside the cylinder body 1. The adjustable counterweight assembly 40 includes a counterweight rod 41 and symmetrically arranged rotation adjustment members 42. Adjusting rods 43 are respectively connected between the rotation adjustment members 42 and the counterweight rod 41. Moving openings 45 are respectively formed at both ends of the counterweight rod 41. The adjusting rods 43 are respectively inserted into the corresponding moving openings 45. Limiting mechanisms 44 for preventing the counterweight rod 41 from sliding up and down are respectively provided at both ends of the counterweight rod 41. The rotation adjustment member 42 includes an annular limiting block 421 embedded in the opposite ends of the end cover 2. A rotating rod 422 is fixedly connected inside the annular limiting block 421. Countersunk holes one 423 are respectively formed at the opposite ends of the hollow roller shafts 3. One end of the rotating rod 422 is fixedly connected to the adjusting rod 43, and the other end is threadedly connected with a locking nut 424. The locking nut 424 is in abutting connection with the inner wall of the countersunk hole one 423; the hollow roller shafts 3 are connected to the other side of the end cover 2, and are used for supporting the cylinder body 1, transmitting power or realizing a specific rotation function. Its hollow design can not only reduce the weight and increase the strength, but also provide an installation space for the rotation adjustment member 42. The surface of the cylinder body 1 is wrapped with rubber. The uneven mass distribution on the surface of the cylinder body 1 can be determined by visual inspection, ultrasonic detection and other detection methods. By using a socket wrench and other related tools, the locking nut 424 is loosened, so that the staff can observe and adjust the circumferential distribution position of the counterweight rod 41 in the cylinder body 1 through the fan-shaped opening 5, and make precise adjustment according to the direction and magnitude of the unbalance amount, so as to compensate for the unbalance generated by the rubber roller.
[0031] On the opposite side of the adjusting rod 43, a number of first convex teeth 46 are connected at intervals. The limiting mechanism 44 includes a receiving groove 441 formed on the side of the movable opening 45 away from the first convex teeth 46. A driving block 442 is installed in the receiving groove 441. On the side of the driving block 442 close to the first convex teeth 46, a number of second convex teeth 443 are connected at intervals. A counterbore two 444 is formed at one end of the counterweight rod 41. The counterbore two 444 communicates with the receiving groove 441. An adjusting bolt 445 whose second convex teeth 443 are meshed with the first convex teeth 46 is threadedly connected in the counterbore two 444. One end of the adjusting bolt 445 is rotatably connected to the driving block 442, and the driving block 442 is always located in the receiving groove 441. The staff observes the initial distance between the counterweight rod 41 and the inner wall of the cylinder body 1 through the fan-shaped opening 5, and by rotating the adjusting bolt 445, adjusts the distance between the counterweight rod 41 and the inner wall of the cylinder body 1, changes the centrifugal force generated during the rotation of the counterweight rod 41, realizes the change of the counterweight of the counterweight rod 41, achieves precise adjustment. At the same time, by tightening the adjusting bolt 445, the first convex teeth 46 and the second convex teeth 443 are engaged with each other to limit the counterweight rod 41 and prevent it from moving.
[0032] Reinforcing ribs 6 are connected to the end cover 2 and are matched with the number of fan-shaped openings 5. One end of the reinforcing rib 6 is connected to the cylinder body 1, and the other end is connected to the roller shaft. The reinforcing rib 6 is used to reduce the stress concentration phenomenon at the connection between the end cover 2 and the cylinder body 1, disperse the stress and load generated during the operation of the roller, thereby improving the overall structural strength of the roller.
[0033] On the opposite side of the adjusting rod 43, there is a color scale mark 7; the color scale mark 7 forms an indication area on the adjusting rod 43 through different colors or the change of color depth, enabling the operator to intuitively see the current position of the counterweight rod 41. At the same time, the color scale mark 7 reduces the adjustment error caused by human judgment errors. The operator only needs to align the counterweight rod 41 with the required scale mark to complete precise adjustment.
[0034] The implementation principle of this embodiment is as follows: After the operator detects the area with uneven surface quality distribution of the rubber roller, by using other special tools such as a socket wrench to rotate the locking nut 424, observes and adjusts the circumferential distribution position of the counterweight rod 41 in the cylinder body 1 through the fan-shaped opening 5, adjusts according to the direction of the unbalance amount to compensate for the unbalance generated by the rubber roller, and according to the magnitude of the unbalance amount, rotates the adjusting bolt 445. The adjusting bolt 445 moves threadedly in the counterbore two 444, and at the same time drives the driving block 442 to move in the receiving groove 441, enabling the operator to accurately adjust the position distance of the counterweight rod 41 according to the guidance of the color scale mark 7. After adjusting to the appropriate position, by rotating the adjusting bolt 445, the first convex teeth 46 and the second convex teeth 443 are engaged with each other to limit the counterweight rod 41 and prevent it from moving.
