Technical Field

[0001] This utility model relates to the field of industrial technology, and in particular to a stone roller eccentric counterweight balancing device. Background Technology

[0002] Tension rollers are core tension control devices in industrial continuous production lines, achieving precise separation and stable control of material tension through the principle of tribomechanics. Their design requires comprehensive consideration of material properties (thickness, strength), operating conditions (speed, temperature), and cost to balance rigidity, wear resistance, and economic efficiency; stone rollers are one such type.

[0003] In existing technologies, tension rollers are indispensable. Tension rollers are generally composed of several motor-driven rollers combined together to generate large friction between the rollers and the conveyed material. The tension of the material is changed by driving or braking the motor. This type of tension roller is relatively expensive and has a complex control system. It is not a good choice for some units with small investment, frequent start-stop, and no need for frequent tension adjustment. Utility Model Content

[0004] In view of this, the present invention proposes an eccentric counterweight balancing device for stone rollers, which can adjust the position of the counterweight as needed during the use of the stone rollers, thereby automatically balancing the stone rollers, increasing the material wrap angle or tension, and thus increasing the material tension.

[0022] like Figure 1-4 As shown, this utility model discloses an eccentric counterweight balancing device for a stone roller, comprising a base plate 1, with frames 2 fixedly connected to both sides of the top of the base plate 1. Lifting blocks 3 are disposed within the inner cavity of the frames 2, and a roller body 4 is movably connected between the two lifting blocks 3. Counterweight adjustment components 5 are disposed on both sides of the top of the base plate 1, each comprising two lifting plates 501, fixedly connected to the front and rear sides of the bottom of the lifting blocks 3 respectively. Adjusting rods 502 are fixedly connected to opposite sides of the two lifting plates 501. One end extends through to the outside of frame 2 and is slidably fitted with an adjustment frame 503. The bottom of the adjustment frame 503 is fixedly connected to an installation block 504. The front and rear sides of the installation block 504 are movably connected to a fixing block 505. The bottom of the fixing block 505 is fixedly connected to the base plate 1. The top of the two adjustment frames 503 is fixedly connected to an installation plate 506. A handwheel 507 is provided on the surface of the installation plate 506. A screw 508 is fixedly connected to the surface of the handwheel 507. One end of the screw 508 extends through the installation plate 506 and is fitted with a counterweight 509.

[0023] By setting the counterweight adjustment component 5, the material is conveyed on the roller body 4. When it is necessary to adjust the balance height of the roller body 4, the screw 508 can be rotated by turning the handwheel 507. The rotation of the screw 508 can adjust the position of the counterweight 509. By adjusting the position of the counterweight 509, the lever formed by the adjustment frame 503 can be adjusted, thereby raising or lowering the roller body 4 and adjusting the material tension.

[0024] like Figures 1-4 As shown, sliders 510 are fixedly connected to both the front and rear sides of the counterweight 509. The surface of the adjusting frame 503 is provided with a sliding opening 511 that works in conjunction with the slider 510. The surface of the slider 510 is slidably connected to the inner wall of the sliding opening 511.

[0025] One end of the screw 508 is rotatably connected to a support plate 512, and the surface of the support plate 512 is fixedly connected to the adjustment frame 503.

[0026] By setting the sliding opening 511, the movement range of the slider 510 can be limited. By setting the sliding opening 511 and the slider 510, the stability of the counterweight 509 adjustment can be improved. By setting the support plate 512, one end of the screw 508 can be supported, thereby improving the stability of the screw 508.

[0027] like Figures 1-4 As shown, the surface of the screw 508 is movably connected to the support plate 512 and the mounting plate 506 through the first bearing, and the surface of the screw 508 is connected to the counterweight 509 through a thread.

[0028] The surface of the handwheel 507 is provided with anti-slip texture, and the surface of the adjustment bracket 503 is fixedly connected with the scale mark 513.

[0029] By setting the first bearing, the connection between the screw 508 and the mounting plate 506 and the support plate 512 can be facilitated. By setting the thread, the use of the counterweight 509 can be facilitated. By setting the anti-slip texture, it can play an anti-slip role. By setting the scale mark 513, the counterweight 509 can be adjusted precisely.

[0030] like Figures 1-4 As shown, one side of the lifting block 3 is rotatably connected to the roller body 4 through the second bearing, and the surface of the mounting block 504 is movably connected to the fixing block 505 through the rotating shaft.

[0031] Limiting frames 6 are fixedly connected to the front and rear sides of the top of the lifting block 3. Springs 7 are sleeved on the surface of the limiting frame 6, and the top of the limiting frame 6 extends through to the top of the frame 2.

[0032] By setting a second bearing, the roller 4 can be easily adjusted; by setting a rotating shaft, the connection between the mounting block 504 and the fixing block 505 can be easily made; by setting a limit frame 6, the stability of the lifting block 3 adjustment can be improved; and by setting a spring 7, the lifting block 3 can be easily reset.

[0033] The working principle of the eccentric counterweight balancing device for stone rollers of this utility model is as follows: Material is conveyed through the surface of roller body 4. When it is necessary to adjust the material tension, the screw 508 can be rotated by the handwheel 507. The rotation of the screw 508 can drive the counterweight block 509 to move. The movement of the counterweight block 509 will adjust the lever formed by the adjusting frame 503. The movement of the counterweight block 509 away from the fixed block 505 will cause one end of the adjusting frame 503 to press down. The other end of the adjusting frame 503 will cause the adjusting rod 502 to move upward. The adjusting rod 502 can drive the roller body 4 to move upward for adjustment through the cooperation of the lifting plate 501 and the lifting block 3. The movement of the counterweight block 509 closer to the fixed block 505 will cause one end of the adjusting frame 503 to rise. The other end of the adjusting frame 503 will drive the adjusting rod 502 to move downward. The adjusting rod 502 can drive the roller body 4 to move downward for adjustment through the cooperation of the lifting plate 501 and the lifting block 3. It can be adjusted according to the tension of the conveyed material, and plays an automatic balancing role.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
