Description

Technical Field

[0001] The utility model belongs to the technical field of refiners, in particular to a power transmission mechanism of a refiner. Background Art

[0002] The refiner is a rubber mixing machine used to remove hard impurities contained in recycled rubber. The surface of the front and rear rollers is smooth and slightly drum-shaped. When the refiner is running, it can squeeze the hard impurities contained in the rubber from the center of the roller to the two ends and gather them on the edge of the rubber sheet. Then the impurities on the edge of the rubber are removed with a cutter.

[0003] Among them, the file A recycled rubber refining machine is disclosed, which mainly solves the problem of poor roller cooling effect, which leads to low production efficiency. However, it is found in the long-term use process that when the distance between the two sets of rollers needs to be adjusted according to actual production, the existing power transmission mechanism also needs to be adjusted synchronously. If no adjustment is made, it is easy to cause the shaft of the driving motor and the roller to be out of sync and produce abnormal noise. In order to optimize this solution, practitioners have designed a power transmission mechanism of the refiner. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1:

[0024] Combination Figures 1 to 4 The power transmission mechanism of the refiner shown includes a refiner body 1, the bottom of the refiner body 1 is equipped with an adjustable support foot, which is convenient for adjusting the position of the refiner body 1 on the horizontal plane to ensure the stability of subsequent use. Two sets of support platforms 2 are relatively arranged on the upper surface of the refiner body 1. The support platforms 2 can ensure that the recycled rubber is put in from the top of the roller 4 in the subsequent work and recovered from the bottom. Two sets of bearing seats 3 are arranged on the inner walls of the two sets of support platforms 2. The roller 4 is rotatably arranged between the two sets of bearing seats 3 on the same side. A power transmission mechanism 5 is arranged on the upper surface of the refiner body 1 on one side of the roller 4. The power transmission mechanism 5 is used to control the rotation of the roller 4. The power transmission mechanism 5 is arranged on the outer side to facilitate fine adjustment to maintain the best driving roller 4 rotation position;

[0025] The power transmission mechanism 5 includes a transmission case 501, which is the main bearing transmission part. The interior of the transmission case 501 is hollow to facilitate the subsequent component arrangement. An oil filling hole 508 is arranged at the top center of the transmission case 501. The position of the oil filling hole 508 can realize that when lubricating oil is added to the interior of the transmission case 501, the lubricating oil can be directly poured on the internal transmission components. Two groups of driving gears 502 are rotatably arranged at the bottom of the cavity of the transmission case 501. A driving motor 503 for controlling the rotation of the driving gear 502 is arranged on the outside of the transmission case 501. The rotating shaft of the driving motor 503 is connected to the end of the driving gear 502 through a coupling 504. A driven gear set 505 is arranged on the driving gear 502. At least two groups of driven gear sets 505 are arranged, so that the most basic transmission ratio can be guaranteed. A transmission gear is arranged above the driven gear set 505. 506, the end of the transmission gear 506 passes through the transmission box 501 and is provided with a universal transmission shaft 507, the other end of the universal transmission shaft 507 is connected to the roller 4, the main working principle of the power transmission mechanism 5 is to start the driving motor 503 to drive the driving gear 502 to rotate, and then the driving gear 502 engages the driven gear set 505 to rotate it, the driven gear set 505 acts on the transmission gear 506 to rotate it, and finally the transmission gear 506 drives the universal transmission shaft 507 to rotate and then acts on the roller 4 to rotate. Firstly, due to the addition of the universal transmission shaft 507, the power transmission mechanism 5 will not be interfered when the roller 4 finely adjusts its position, so no abnormal noise will be generated. In addition, the multi-stage transmission setting has the advantages of strong conveying capacity, high-speed and stable operation, low noise, simple structure, and convenient program control.

[0026] In this embodiment, a water cooling pipe 6 is arranged on the inner wall of the roller 4 cavity, and the water cooling pipe 6 is fixedly arranged on the side wall of the support platform 2. In this arrangement, the water cooling pipe 6 does not contact the roller 4. Therefore, during the rotation of the roller 4, the water cooling pipe 6 will not be affected by the rotation.

[0027] In this embodiment, one group of the two groups of rollers 4 is fixedly installed, and the other group is adjustably installed, so that the distance between the two groups of rollers 4 can be adjusted according to actual needs. A rocking wheel 7 for changing the position of the adjustable rollers 4 is arranged on the side wall of the support platform 2. This method belongs to the existing technology. The rocking wheel 7 is a wheel with a built-in propulsion screw, so that the adjustable rollers 4 can be propulsed by simple rotation.

[0028] In this embodiment, a raised platform is provided at the bottom of the driving motor 503, and the height of the driving motor 503 is kept the same as the height of the driving gear 502, so as to ensure the most basic optimal position of the driving roller 4 rotation. The driving motor 503 adopts a permanent magnet synchronous motor. The permanent magnet synchronous motor is more energy-saving during use, and the power saving can reach more than 10%.
