Description

Technical Field

[0001] This utility model relates to the field of roller press technology, and in particular to a roller press tension adjustment component. Background Technology

[0002] During the electrode rolling process, the tension generated by the electrodes before and after the rolling mill is generally relatively large. Therefore, in order to facilitate the adjustment of the tension on the electrodes, adjustment mechanisms are set before and after the rolling mill. The swing roller swings in the circumferential direction to adjust the tension and meet the tension requirements of the electrodes entering and leaving the rolling mill.

[0003] In this adjustment mechanism, the rotation of the shaft drives the swing arm to swing, which in turn causes the swing roller supported between the swing arms to swing in a circumferential direction, thereby adjusting the tension. In order to maintain a balanced tension at both ends of the pressure roller, the axes of the swing roller and the shaft must be kept parallel and without deviation. This requires adjustment of the swing roller. Currently, the common method is to adjust the swing arm on the non-drive end of the shaft to adjust the axis of the swing roller.

[0004] The existing connection structure between the swing arm and the shaft on the non-drive side of the shaft can be either a tension sleeve or a threaded connection. The tension sleeve is locked by friction, but it is prone to wear when subjected to greater tension, which affects its service life. The other connection method is a threaded connection with a flat key for positioning, but this requires high precision in the machining of the parts. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a roller press tension adjustment component that is easy to process and has a better adjustment effect.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a tension adjustment component for a roller press, including a swing roller and a rotating shaft parallel to the axis of the swing roller. A first swing arm is provided between the driving end of the rotating shaft and the left end of the swing roller, and a second swing arm is provided between the non-driving end of the rotating shaft and the right end of the swing roller. The swing roller is rotatably supported between the upper ends of the first swing arm and the upper ends of the second swing arm. The lower end of the first swing arm is drivenly connected to the driving end of the rotating shaft. A transition plate is drivenly connected to the non-driving end of the rotating shaft. The lower end of the second swing arm is loosely fitted onto the non-driving end of the rotating shaft. The transition plate has a plurality of circumferentially distributed waist-shaped holes, and the second swing arm has a plurality of circumferentially distributed through holes. The transition plate and the second swing arm are fixedly connected by fastening bolts passing through the waist-shaped holes and through holes.

[0007] Specifically, a first support is fixed to the upper end of the first swing arm, a second support is fixed to the upper end of the second swing arm, a central shaft passing through the swing roller is fixed between the first support and the second support, and rolling bearings are respectively installed in the inner holes at the left and right ends of the swing roller, with the inner ring of the rolling bearings having a clearance fit with the central shaft.

[0008] Furthermore, to facilitate the angle adjustment of the second swing arm, top blocks are fixed on the front and rear sides of the adapter plate, and adjusting bolts that press against the side of the second swing arm during adjustment are connected to the top blocks.

[0009] Preferably, a transmission key is provided between the inner hole of the adapter plate and the rotating shaft, and a set screw for pressing the transmission key is connected to the side of the adapter plate.

[0010] Preferably, the adapter plate has four circumferentially distributed waist-shaped holes, and the second swing arm has four circumferentially distributed through holes.

[0011] The beneficial effects of this utility model are as follows: This utility model changes the traditional method of directly connecting the swing arm and the rotating shaft. By installing an adapter plate on the non-transmission end of the rotating shaft, the second swing arm can be adjusted by using the waist-shaped hole on the adapter plate, thereby realizing the angle adjustment of the swing roller in the circumferential direction and achieving the purpose of adjusting the tension at both ends of the pressure roller. This connection structure reduces the processing precision requirements of the parts and effectively improves the service life of the adjustment components. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] like Figures 1-5 The tension adjustment assembly of the roller press shown includes a swing roller 1 and a rotating shaft 2 with their axes parallel to each other. A first swing arm 3 is provided between the driving end of the rotating shaft 2 and the left end of the swing roller 1, and a second swing arm 4 is provided between the non-driving end of the rotating shaft 2 and the right end of the swing roller 1. Both the first swing arm 3 and the second swing arm 4 are plate-shaped structures with a round top and a round bottom. A shaft hole is provided at the center of the circular plate at the lower part of the first swing arm 3 and the lower part of the second swing arm 4.

[0021] Specifically, a first support 8 is fixed to the upper end of the first swing arm 3, and a second support 9 is fixed to the upper end of the second swing arm 4. A central shaft 10 passing through the swing roller 1 is fixed between the first support 8 and the second support 9. Rolling bearings 13 are respectively installed in the inner holes at the left and right ends of the swing roller 1. The inner ring of the rolling bearing 13 is fitted with the central shaft 10 with a small clearance. Through the action of the rolling bearings 13, the swing roller 1 is rotated and supported between the upper ends of the first swing arm 3 and the upper ends of the second swing arm 4.

[0022] The lower end of the first swing arm 3 is installed on the transmission end of the rotating shaft 2 through its shaft hole, and the first swing arm 3 and the rotating shaft 2 are connected by a flat key. A transition plate 5 is fitted on the non-transmission end of the rotating shaft 2. A transmission key 15 is provided between the inner hole of the transition plate 5 and the rotating shaft 2. A set screw 16 for pressing the transmission key 15 is connected to the side of the transition plate 5. The transition plate 5 and the rotating shaft 2 are connected by the transmission key 15. The lower end of the second swing arm 4 is fitted on the non-transmission end of the rotating shaft 2 through its shaft hole and fits against the right side of the transition plate 5.

[0023] The adapter plate 5 has four circumferentially distributed waist-shaped holes 6, and correspondingly, the second swing arm 4 has four circumferentially distributed through holes 7. The adapter plate 5 and the second swing arm 4 are fixedly connected by fastening bolts 14 passing through the waist-shaped holes 6 and the through holes 7.

[0024] To facilitate the adjustment of the second swing arm 4, top blocks 11 are fixed on the front and rear sides of the adapter plate 5, and adjusting bolts 12 are connected to the top blocks 11 to press against the side of the second swing arm 4 during adjustment.

[0025] When adjusting the tension, the cylinder drives the rotating shaft 2 to rotate, which in turn drives the swing roller 1 to swing in the circumferential direction via the first swing arm 3 and the second swing arm 4 to adjust the tension appropriately. If there is a misalignment between the axis of the rotating shaft 2 and the axis of the swing roller 1, resulting in an imbalance of tension at both ends of the swing roller 1, the installation position of the second swing arm 4 can be adjusted through the oblong hole 6 to adjust the angle of the swing roller 1 in the circumferential direction, so as to achieve parallelism between the axis of the swing roller 1 and the axis of the rotating shaft 2, thereby ensuring that the tension at both ends of the swing roller 1 is balanced.

[0026] When adjusting the second swing arm 4, first loosen the fastening bolt 14 between the adapter plate 5 and the second swing arm 4, then push the second swing arm 4 with the swing roller 1 to rotate to the appropriate position by adjusting the bolt 12. After the adjustment is completed, fix the adapter plate 5 and the second swing arm 4 with the fastening bolt 14.

[0027] This invention uses an adapter plate 5 mounted on the non-transmission end of the rotating shaft 2. Fastening bolts 14 pass through the oblong hole 6 and through hole 7 to fix the adapter plate 5 to the second swing arm 4. The oblong hole 6 on the adapter plate 5 is used to adjust the installation angle of the second swing arm 4, thereby realizing the adjustment of the swing roller 1 in the circumferential direction. This ensures that the swing roller 1 is parallel to the axis of the rotating shaft 1, achieving the purpose of adjusting the tension at both ends of the roller press. This connection structure can reduce the processing accuracy requirements of the parts and effectively improve the service life of the adjustment components.

[0028] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
