TECHNICAL FIELD

[0001] The present application relates to the technical field of gap adjustment between oil rollers of hydraulic rolling equipment, in particular to an oil roller gap adjustment device. BACKGROUND

[0002] It is well known that there are various types of hydraulic crushers and other oil rolling equipment at home and abroad. At present, the commonly used crushers or rolling machines include double roller and double pair roller rolling machines. The former has small roller pressure and is inconvenient to adjust, and the crushing or rolling effect is not good.

[0003] The latter has large roller pressure and high speed, so the unit processing capacity is large. The existing various crushers or rolling machines have the problems of low yield, poor crushing or rolling effect, unstable hydraulic system, frequent failures, easy wear of transmission belt (especially vertical transmission), and the like. In addition, the gap adjustment between rollers of the crusher or rolling machine is difficult, and the rollers are prone to peeling and edge dropping, the service life of the rollers is short, and the parts are prone to damage (such as bearing damage). Therefore, the oil roller of the rolling machine needs to be replaced and disassembled frequently. Due to the large volume and weight of the oil roller, replacement and disassembly are very difficult. In addition, the maintenance, installation and disassembly of the oil roller of the rolling machine are very large at home and abroad. In addition, the oil roller has large volume and weight, and is difficult to replace and disassemble. The safety, accuracy, quality and efficiency of disassembly are low, and the cost is high. At present, electric hoists or hand hoists are used for lifting and disassembling, and special disassembly and installation tools or devices for oil rollers are also used. The disassembly and installation tools or devices need to be separately equipped, and have relatively complex structure and high cost. In addition, the oil roller has large volume and weight, and is difficult to replace and disassemble. In addition, the adjustment device of the piston rod of the oil cylinder on the market directly acts on the working surface by adjusting the rear end of the piston rod of the oil cylinder. After the roller wears, the oil cylinder must be disassembled to add a gasket at the rear end of the piston rod for compensation. In this process, the rolling machine oil roller needs to be disassembled and installed, which affects the production efficiency. These problems have become urgent problems to be solved in the adjustment of the gap between the rollers of the oil crushing or rolling machine. SUMMARY

[0004] The present application aims at improving the prior art, overcoming the shortcomings and defects of the prior art, and providing a gap adjustment mechanism or device for the oil rollers at both ends of the crusher or the roll mill, which can directly adjust the gap between the rollers of the crusher or the roll mill without disassembling the oil rollers of the roll mill, and has the advantages of simple structure, safety and stability, no disassembly, accuracy and safety, low cost and high efficiency.

[0006] B, the cylinder connecting and mounting mechanism comprises a front upright column 27, a mounting plate 23 arranged on the front upright column 27, a hexagonal slotted nut 28, an arcuate plate 29, a butterfly spring connecting shaft 30 and a butterfly spring 31, wherein the arcuate plate 29 is mounted on the bearing seat assembly 34 of the base 37 of the roll mill roll 36 through the hexagonal slotted nut 28, the butterfly spring connecting shaft 30 and the butterfly spring 31, and the mounting plate 23 is fixedly connected with the rear cylinder cover 10 of the cylinder part by a bolt 32, as shown in Figures 1-8.

[0007] C. The oil cylinder adjusting mechanism comprises a hollow screw rod 1 arranged in the piston rod 14 of the oil cylinder part, an adjusting screw rod 25 arranged in the hollow screw rod 1, and an oil cylinder locking nut 24 and an internal hexagonal bolt 26, wherein the hollow screw rod 1 is externally threaded, the piston rod 14 of the oil cylinder part is internally threaded, and the internal thread of the piston rod 14 and the external thread of the hollow screw rod 1 are matched to realize the fast left-right movement and positioning of the rolling mill movable roller sliding bearing body through threaded engagement movement. The adjusting screw rod 25 is extended through the arcuate plate 29 of the oil cylinder connecting and mounting mechanism at the right end and is connected with the bearing seat assembly 34 on the base 37 of the rolling mill roller 36 through threading, as shown in Figs. 1-8.

[0008] The working process and principle of the present technology are as follows: first, the present application is installed on the oil cylinder connecting mechanism, which comprises a front column 27, an installation plate 23 arranged on the front column 27, a hexagonal slotted nut 28, an arch-shaped plate 29, a butterfly spring connecting shaft 30, and a butterfly spring 31 installed on the embryo rolling machine, that is, the arch-shaped plate 29 of the oil cylinder connecting mechanism is installed on the bearing seat assembly 34 of the embryo rolling roller 36 of the embryo rolling machine through the hexagonal slotted nut 28, the butterfly spring connecting shaft 30, and the butterfly spring 31, and the installation plate 23 is fixedly connected to the rear cylinder cover 10 of the oil cylinder part through the bolt 32, then the oil cylinder locking nut 24 is locked by adjusting the lead screw 25, and at the same time, the internal hexagonal bolt 26 is locked, at this time, the piston 17 is located at the left end position of the oil cylinder, and the oil cylinder is in the initial position, as shown in FIG. 4; when the hydraulic oil enters the oil cylinder cavity from the oil inlet 7, the hydraulic oil pushes the piston 17 to move backward, and the piston 17 and the piston rod 14 are cooperatively installed through the stop washer 21 and the circular nut 22, so that the piston rod 14 also moves synchronously; because the piston rod 14 is provided with a hollow lead screw 1, the hollow lead screw 1 is provided with an adjusting lead screw 25 and an oil cylinder locking nut 24 and an internal hexagonal bolt 26 matched therewith, wherein the hollow lead screw 1 is provided with external threads, and the piston rod 14 of the oil cylinder part is provided with internal threads, which are matched by thread engagement, when the piston 17 moves backward, the adjusting lead screw 25, the oil cylinder locking nut 24, the internal hexagonal bolt 26, the piston rod 14, and the hollow lead screw 1 will finally move backward, because the hollow lead screw 1 is located on the end surface of the arch-shaped plate 29, so the arch-shaped plate 29 also moves backward, at the same time, the excess hydraulic oil in the oil cylinder flows back to the pump station from the oil outlet 8, when the oil cylinder is in contact with the inner side surface of the rear cylinder cover 10, the oil cylinder stroke is in place, as shown in FIG. 5; when the oil cylinder gap adjusting device (or equipment) needs to be fine-tuned and compensated after the oil cylinder stroke is in place, the oil cylinder locking nut 24 and the internal hexagonal bolt 26 can be loosened and rotated outward by a certain distance, at this time, because the hollow lead screw 1 is provided with external threads, and the piston rod 14 of the oil cylinder part is provided with internal threads, the two are matched by thread engagement, and the piston rod 14 is in a fixed state because the piston 17 is in place, so only the hollow lead screw 1 needs to be rotated by using a wrench, the rotated hollow lead screw 1 moves to the right again, and because the hollow lead screw 1 is always in contact with the end surface of the arch-shaped plate 29, the arch-shaped plate 29 continues to move to realize fine-tuning and compensation, as shown in FIG. 6.The process of the combination and separation of the rollers in the specific production is as follows: when the combination of the rollers is needed, the oil cylinder locking nut 24 needs to be locked first, and then the internal hexagonal bolt 26 is locked after the locking, and the piston 17 is at the front end of the oil cylinder, at this time the oil cylinder is at the initial position; when the hydraulic oil enters the oil cylinder cavity from the oil inlet 7, the hydraulic oil pushes the piston 17 to move to the right, and the piston 17 and the piston rod 14 are installed through the stop washer 21 and the round nut 22, so the piston rod 14 also moves synchronously. Because the hollow screw rod 1 is arranged in the piston rod 14, the adjusting screw 25 and the oil cylinder locking nut 24 and the internal hexagonal bolt 26 matched therewith are arranged in the hollow screw rod 1, wherein the hollow screw rod 1 is externally provided with external threads, the piston rod 14 of the oil cylinder part is internally provided with internal threads, and the two are matched through thread engagement; therefore, when the piston 17 moves backward, the adjusting screw 25, the oil cylinder locking nut 24, the internal hexagonal bolt 26, the piston rod 14 and the hollow screw rod 1 are finally moved backward; because the hollow screw rod 1 is on the end surface of the arch-shaped plate 29, the arch-shaped plate 29 is assembled with the bearing seat assembly 34 through the butterfly spring 31, the butterfly spring connecting shaft 30 and the hexagonal slotted nut 28, and the bearing seat assembly 34 and the roller 36 form a component; therefore, when the piston rod 14 moves, the roller 36 is finally moved; when the roller 36 moves to the specified position, the equipment starts to work; after a certain period of use, the roller 36 is worn and the diameter becomes smaller, resulting in that the gap between the two rollers becomes larger; but the stroke of the oil cylinder has reached the position and cannot be moved any more, at this time because the hollow screw rod 1 is externally provided with external threads, the piston rod 14 of the oil cylinder part is internally provided with internal threads, and the two are matched through thread engagement, and the piston rod 14 is in a fixed state because the piston 17 is in the position, so only the hollow screw rod 1 needs to be rotated by using a wrench, and the rotated hollow screw rod 1 moves to the right again.When the gap between the rollers needs to be adjusted, the oil cylinder locking nut 24 and the inner hexagonal bolt 26 are locked, so that the hydraulic oil enters the oil outlet 8 and the oil inlet 7, pushing the piston 17 in the oil cylinder to move to the left until the piston 17 is attached to the inner side of the front cylinder cover 5, and the oil cylinder return stroke is in place. In this process, the piston 17 and the piston rod 14 are installed by the stop washer 21 and the round nut 22, so that the piston rod 14 also moves synchronously. Because the piston rod 14 is provided with the hollow screw 1, the hollow screw 1 is provided with the adjusting screw 25, and the oil cylinder locking nut 24 and the inner hexagonal bolt 26 are matched, the outer thread of the hollow screw 1 is provided, and the inner thread of the piston rod 14 of the oil cylinder part is provided. When the piston 17 moves backward, the hollow screw 1 moves to the left. Because the hollow screw 1 is in contact with the end surface of the oil cylinder locking nut 24 during the return stroke, the oil cylinder locking nut 24 is threadedly connected with the adjusting screw 25, so that the adjusting screw 25 moves forward synchronously. At this time, because the adjusting screw 25 is threadedly connected with the bearing seat assembly 34, and the bearing seat assembly 34 is connected with the rolling mill roller 36 to form an integral assembly, when the hollow screw 1 moves to the left, the rolling mill roller 36 moves to the left, so that the rollers are separated.

[0009] The beneficial effects of the present technology or the characteristics compared with the existing technology are: the present technology belongs to the gap adjusting device of the oil rolling mill roller, which overcomes the shortcomings and defects of the existing technology, and provides a gap adjusting device for the oil rolling mill roller, which can directly adjust the gap between the rollers of the crusher or the rolling mill without disassembling the oil rolling mill roller. The device has the advantages of simple structure, safety and stability, no disassembly, accuracy and safety, low cost and high efficiency. BRIEF DESCRIPTION OF DRAWINGS
