[0014] The present invention provides a novel hydraulic distance adjustment device for a rubber mixing machine, which has the following beneficial effects:

[0015] (1) The invention adjusts the distance between the squeezing rollers by moving the squeezing rollers so that the roller distances at both ends of the squeezing rollers are consistent during adjustment, which is convenient for adjusting the thickness of the film. It has a wide range of applications and can meet different needs. It prevents the hydraulic adjustment structure from moving rapidly when the PLC intelligent controller controls the hydraulic adjustment structure to move, causing the internal pressure of the hydraulic system to change rapidly, which may cause additional pressure shocks to the hydraulic components, seals and pipelines in the system, thereby accelerating their wear and aging. The arrangement of the hydraulic cylinder and the hollow tube can ensure that the roller distance is always within the specified range during the distance adjustment process, preventing the occurrence of roller collision and improving the protection effect of the equipment.

[0016] (2) The invention causes the threaded block to reciprocate along the reciprocating spiral groove through the reciprocating spiral groove. The reciprocating movement of the threaded block along the reciprocating spiral groove drives the connecting plate and the rubber turning rod to reciprocate. The reciprocating movement of the rubber turning rod makes the rubber material evenly distributed between the rollers of the rubber mixer, thereby preventing the rubber material from accumulating or piling up on the roller surface, thereby ensuring the uniformity and consistency of mixing. The fixed plate moves toward the middle of the rotating rod and contacts the T-shaped rod, and is subjected to the reverse thrust of the T-shaped rod, so that the fixed plate drives the rotating plate to rotate upward. The upward rotation of the rotating plate drives the rubber material to move upward, thereby preventing the rubber material from getting stuck between the rollers and affecting the mixing effect.

[0017] (3) In the present invention, the downward movement of the cylinder will cause the oil outlet hole to separate from the oil outlet port, resulting in loss of the seal of the oil outlet port on the oil outlet hole, causing the lubricating oil inside the oil storage tank to flow through the oil outlet hole to the output end of the motor, thereby lubricating the output end of the motor with the lubricating oil to prevent the lack of lubrication from causing increased friction inside the motor, especially at the contact surface between the bearing and other moving parts, which will cause increased wear of the parts and may even cause serious damage. When the brush moves downward, it will contact the output end of the motor, and the brush can make the lubricating oil more evenly applied, thereby improving the overall lubrication effect and preventing waste.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 4One embodiment of the present invention is: a new type of hydraulic distance adjustment device for a rubber mixing machine, comprising: a support frame 1, a No. 1 motor 2 is fixedly installed on the surface of the support frame 1, and an extrusion roller 3 is fixedly installed on the output end of the No. 1 motor 2; a hydraulic distance adjustment device, the hydraulic distance adjustment device is arranged on the surface of the support frame 1, and the hydraulic distance adjustment device includes a fixed frame 4, a PLC intelligent controller 5, a hydraulic adjustment structure 6, a No. 2 motor 7, a slider 8, a hydraulic cylinder 9, a hollow tube 10, a ring 11, a hollow rod 12, a liquid inlet 13 and a sealing plate 14. The distance between the extrusion rollers 3 is adjusted by moving the extrusion rollers 3, so that the roller distances at both ends of the extrusion rollers 3 are consistent during adjustment, which is convenient for adjusting the thickness of the film and has a wide range of applications. The fixed frame 4 is fixedly installed on the surface of the support frame 1, the PLC intelligent controller 5 is fixedly installed on the top of the fixed frame 4, the hydraulic adjustment structure 6 is fixedly installed on the surface of the support frame 1, and the surface of the support frame 1 A slide groove is provided, a slider 8 is slidably mounted on the inner wall of the slide groove, the No. 2 motor 7 is fixedly mounted on the surface of the slider 8, the extrusion roller 3 is fixedly mounted on the output end of the No. 2 motor 7, the output end of the hydraulic adjustment structure 6 is fixedly mounted on the fixed end of the No. 2 motor 7, the hydraulic cylinder 9 is fixedly mounted on the inner wall of the slide groove, the hollow tube 10 is slidably mounted on the inner wall of the hydraulic cylinder 9, the ring 11 is fixedly mounted on the inner wall of the hollow tube 10, the hollow tube 10 is fixedly mounted on the surface of the slider 8, the hollow rod 12 is fixedly mounted on the inner wall of the hydraulic cylinder 9, the liquid inlet hole 13 is provided on the surface of the hollow rod 12, and the sealing plate 14 is fixedly mounted on the end of the hollow rod 12 away from the hydraulic cylinder 9 to prevent the PLC intelligent controller 5 from controlling the hydraulic adjustment structure 6 to move, and the rapid movement of the hydraulic adjustment structure 6 causes the internal pressure of the hydraulic system to change rapidly, which may cause additional pressure shock to the hydraulic components, seals and pipelines in the system, thereby accelerating their wear and aging.

[0028] The PLC intelligent controller 5 is electrically connected to the hydraulic adjustment structure 6 , a liquid is arranged inside the hydraulic cylinder 9 , and the sealing plate 14 is attached to the inner wall of the hollow tube 10 , so that the sealing effect is improved by the sealing plate 14 being attached to the inner wall of the hollow tube 10 .

[0029] When the present embodiment is working, the hydraulic adjustment mechanism 6 is controlled by the PLC intelligent controller 5 to perform oil pressure distance adjustment. The movement of the hydraulic adjustment mechanism 6 will drive the No. 2 motor 7 and the squeezing roller 3 to move. The distance between the squeezing rollers 3 is adjusted by the movement of the squeezing rollers 3, so that the roller distances at both ends of the squeezing rollers 3 are consistent during adjustment, which is convenient for adjusting the thickness of the film. It has a wide range of applications and can meet different needs. At the same time, when the No. 2 motor 7 moves toward the direction close to the No. 1 motor 2, it will drive the slider 8 to move toward the direction close to the No. 1 motor 2. The movement of the slider 8 toward the direction close to the No. 1 motor 2 will drive the hollow tube 10 and the ring 11 to squeeze the liquid inside the hydraulic cylinder 9, so that the liquid can pass through. The liquid enters the hollow rod 12 through the liquid inlet hole 13, and then enters the hollow tube 10 through the hollow rod 12. As the ring 11 moves, the speed at which the liquid enters the hollow rod 12 through the liquid inlet hole 13 will slowly decrease, preventing the PLC intelligent controller 5 from controlling the hydraulic adjustment structure 6 to move, and preventing the hydraulic adjustment structure 6 from moving quickly, causing the internal pressure of the hydraulic system to change rapidly. This may cause additional pressure shocks to the hydraulic components, seals and pipelines in the system, thereby accelerating their wear and aging. At the same time, the setting of the hydraulic cylinder 9 and the hollow tube 10 can ensure that the roller distance is always within the specified range during the distance adjustment process, prevent the roller collision phenomenon from occurring, and improve the protection effect on the equipment.

[0030] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, a rubber turning device is arranged on the inner wall of the support frame 1, and the rubber turning device includes a pulley 151, a rotating wheel 152, a rotating rod 153, a fixed rod 154, a threaded block 155, a connecting plate 156 and a rubber turning rod 157. The pulley 151 is fixedly mounted on the surface of the extrusion roller 3, the rotating wheel 152 is rotatably mounted on the inner wall of the support frame 1, the pulley 151 and the rotating wheel 152 are connected by a belt transmission, the rotating rod 153 is fixedly mounted on the surface of the rotating wheel 152, the surface of the rotating rod 153 is provided with two reciprocating spiral grooves, the two reciprocating spiral grooves are opposite, the threaded block 155 is threadedly mounted on the surface of the rotating rod 153, the connecting plate 156 is fixedly mounted on the circumferential surface of the threaded block 155, and the rubber turning rod 157 is fixedly mounted on the surface of the connecting plate 156. The rubber material is evenly distributed between the rollers of the rubber mixer through the reciprocating motion of the rubber turning rod 157, which can avoid the accumulation or accumulation of the rubber material on the roller surface, thereby ensuring the uniformity and consistency of mixing.

[0031] A rotating plate 158 is rotatably installed on the inner wall of the connecting plate 156, a fixed plate 159 is fixedly installed on the top of the rotating plate 158, a limiting block 1510 is fixedly installed on the inner wall of the connecting plate 156, and a T-shaped rod 1511 is fixedly installed on the circumferential surface of the fixed rod 154. The upward rotation of the rotating plate 158 will drive the rubber material to move upward to prevent the rubber material from being stuck between the rollers and affecting the mixing effect.

[0032] A torsion spring No. 1 is arranged between the connecting plate 156 and the rotating plate 158, and the rotating plate 158 is reset by the torsion spring No. 1. The T-shaped rod 1511 and the fixed plate 159 are in the same horizontal plane. The glue-turning rod 157 contacts the surface of the extrusion roller 3, and the limit block 1510 contacts the surface of the rotating plate 158. Through the contact between the limit block 1510 and the surface of the rotating plate 158, the limit block 1510 limits the rotating plate 158 to only rotate in one direction.

[0033] A lubrication device is arranged on the inner wall of the support frame 1, and the lubrication device includes a push rod 161, a triangular block 162, an L-shaped rod 163, an oil storage tank 164, a triangular plate 165, a cylinder 166 and an inclined plate 167. The push rod 161 is fixedly mounted on the surface of the connecting plate 156, a groove is provided on the inner wall of the support frame 1, the triangular block 162 is slidably mounted on the top of the groove, the L-shaped rod 163 is fixedly mounted on the surface of the triangular block 162, the oil storage tank 164 is fixedly mounted on the top of the inner wall of the groove, the triangular plate 165 is fixedly mounted on the bottom of the L-shaped rod 163, an oil outlet is provided at the bottom of the oil storage tank 164, the cylinder 166 is slidably mounted on the inner wall of the oil outlet, an oil outlet hole is provided on the surface of the cylinder 166, and the inclined plate 167 is fixedly mounted on the top of the cylinder 166. The output end of the motor is lubricated by lubricating oil to prevent lack of lubrication from causing increased internal friction of the motor, especially on the contact surface between the bearing and other moving parts, which will cause increased wear of the parts and may even cause serious damage.

[0034] A collecting frame 168 is fixedly installed at the bottom of the cylinder 166, and a brush 169 is provided at the bottom of the collecting frame 168. The brush 169 can make the lubricating oil more evenly applied, thereby improving the overall lubrication effect and preventing waste.

[0035] A No. 1 spring is arranged between the oil outlet and the cylinder 166 , and the No. 1 spring drives the cylinder 166 to reset, the inclined plate 167 contacts the surface of the triangular plate 165 , and the brush 169 is arranged above the output end of the No. 2 motor 7 .

[0036] The rotation of the extrusion roller 3 drives the pulley 151, the belt and the rotating wheel 152 to rotate, and the rotation of the rotating wheel 152 drives the rotating rod 153 to rotate. The rotation of the rotating rod 153 drives the reciprocating spiral groove to rotate, and the reciprocating spiral groove makes the thread block 155 reciprocate along the reciprocating spiral groove. The reciprocating movement of the thread block 155 along the reciprocating spiral groove drives the connecting plate 156 and the rubber turning rod 157 to reciprocate. The reciprocating movement of the rubber turning rod 157 makes the rubber material evenly distributed between the rollers of the rubber mixing machine, which can avoid the rubber material from accumulating or piling up on the roller surface, thereby ensuring the uniformity and consistency of mixing. The reciprocating motion will drive the rotating plate 158, the fixed plate 159 and the limit block 1510 to reciprocate. The limit block 1510 will limit the rotating plate 158 in one direction, so that when the rotating plate 158 contacts the rubber material, it will not be subjected to the reverse force and rotate in the direction away from the rubber material. The fixed plate 159 moves toward the middle of the rotating rod 153 and contacts the T-shaped rod 1511. The reverse thrust of the T-shaped rod 1511 will cause the fixed plate 159 to drive the rotating plate 158 to rotate upward. The upward rotation of the rotating plate 158 will drive the rubber material to move upward, thereby preventing the rubber material from being stuck between the rollers and affecting the mixing effect.

[0037] The reciprocating motion of the connecting plate 156 drives the push rod 161 to reciprocate. When the push rod 161 moves toward the direction of the support frame 1, it will contact the inclined surface of the triangular block 162. The push rod 161 will push the triangular block 162, the L-shaped rod 163 and the triangular plate 165 to move toward the direction close to the oil storage tank 164. The triangular plate 165 moves toward the direction close to the oil storage tank 164 and contacts the inclined plate 167. The triangular plate 165 will push the inclined plate 167 to move downward. The downward movement of the inclined plate 167 will drive the cylinder 166 to move downward. The downward movement of the cylinder 166 will cause the oil outlet hole to separate from the oil outlet port, and the oil outlet port will lose its sealing on the oil outlet hole, so that the lubricating oil inside the oil storage tank 164 will flow to the output end of the motor through the oil outlet hole. The output end of the machine is lubricated to prevent lack of lubrication from causing increased internal friction in the motor, especially on the contact surface of the bearings and other moving parts, which will cause increased wear of the parts and may even cause serious damage. The connecting plate 156 drives the push rod 161 to move back and forth, so the output end of the motor can be lubricated intermittently to increase the service life of the motor. At the same time, when the cylinder 166 moves downward, it will drive the collection frame 168 and the brush 169 to move downward. The outflowing lubricating oil will enter the inside of the collection frame 168 and then be contaminated on the brush 169. When the brush 169 moves downward, it will contact the output end of the motor. The brush 169 can make the lubricating oil more evenly applied, thereby improving the overall lubrication effect and preventing waste.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
