Description

Technical Field

[0001] The utility model belongs to the technical field of refiners, and in particular relates to a refiner roller position adjustment mechanism. Background Art

[0002] A 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 shaped like a waist drum. When the refiner is running, it can squeeze the hard impurities contained in the rubber from the center of the roller to both ends and gather them on the edge of the rubber. Then the impurities on the edge of the rubber are removed with a cutter.

[0003] Among them, in order to cope with different production needs, the two sets of rollers of the refining machine will be arranged as a fixed roller and a movable roller. The movable roller can be adjusted in position to a certain extent, so that the distance between the two sets of rollers can be adjusted according to actual production. However, the existing movable roller position adjustment mechanism is mostly through the direct spiral advancement of threaded rods set on the side walls of the support platform. This method is not only time-consuming and labor-intensive to adjust, but also it is found during long-term use that the rollers will produce certain vibrations under high-speed rotation. This vibration will cause the threaded rod to slightly withdraw the wire, thereby causing the fixed roller position to slightly retreat, which has a certain impact on the final refined product. In order to optimize this solution, practitioners have designed a refining machine roller position adjustment mechanism. Utility Model Content

[0004] The utility model aims to provide a refiner drum position adjustment mechanism to solve the problem that the existing refiner drum adjustment mechanism is time-consuming and labor-intensive to adjust and may produce slight retreat when the movable drum rotates at high speed.

DETAILED DESCRIPTION

[0020] 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.

[0021] Embodiment 1:

[0022] Combination Figure 1-4 A refiner roller position adjustment mechanism shown in the figure comprises a refiner body 1, two groups of support platforms 2 are arranged oppositely above the refiner body 1, a fixed cylinder 3 and a movable cylinder 4 that cooperate with each other are arranged between the two groups of support platforms 2, when the fixed cylinder 3 and the movable cylinder 4 rotate in cooperation, the hard impurities contained in the rubber material can be squeezed from the center of the roller to the two ends, a transmission mechanism 5 for driving the fixed cylinder 3 and the movable cylinder 4 to rotate is arranged on one side of the support platform 2, the transmission mechanism 5 has a certain adaptive function, and can effectively drive the movable cylinder 4 to rotate even after the position of the movable cylinder 4 is adjusted, the fixed cylinder 3 is fixedly arranged between the two groups of support platforms 2, the movable cylinder 4 is slidably arranged between the two groups of support platforms 2, and an adjustment component 6 for driving the movable cylinder 4 to slide is arranged on the outer wall of the support platform 2, so as to effectively adjust the distance between the fixed cylinder 3 and the movable cylinder 4 to adapt to actual working needs;

[0023] Combination Figure 2The adjustment assembly 6 shown includes an adjustment body 601 arranged on the side wall of the support platform 2, and the adjustment body 601 and the support platform 2 are integrated. A first bearing 602 is arranged in the cavity of the adjustment body 601, and a ball screw nut 603 is sleeved in the first bearing 602. A screw 604 cooperating with the ball screw nut 603 is arranged in the cavity of the ball screw nut 603, and a connector 605 is arranged at the end of the screw nut 604. The connector 605 is fixed to the side wall of the moving cylinder 4, and a toothed disc 606 is fixed at the end of the ball screw nut 603. A threaded rod 607 meshing with the toothed disc 606 is arranged at the bottom of the toothed disc 606, and a second bearing 608 is arranged at the end of the threaded rod 607. The end of the threaded rod 607 is connected to realize its rotation The crank handle 609 of the adjustment component 6 drives the threaded rod 607 to rotate during use by turning the crank handle 609, and then the threaded rod 607 engages the toothed disc 606 to rotate it, and the toothed disc 606 drives the ball screw nut 603 to rotate in the first bearing 602. The rotation process of the ball screw nut 603 drives the internal screw 604 to act with it. At this time, since the connecting piece 605 at the end of the screw 604 is fixed to the side wall of the movable cylinder 4, the screw 604 is prevented from rotating and the screw 604 is pushed forward and backward, and finally acts on the movable cylinder 4 to change its position. This method saves time and effort in the adjustment process. In addition, the internal structural coordination relationship will not cause the screw 604 to retreat due to the vibration caused by the high-speed rotation of the movable cylinder 4.

[0024] In this embodiment, the Figure 1 The transmission mechanism 5 shown includes a transmission box 501 fixedly arranged on the upper surface of the refiner body 1, and a motor 502 for driving the transmission box 501 is arranged on the transmission box 501.

The movable cylinder 4 includes two groups of bearing seats 401 , and a roller 402 is rotatably arranged between the two groups of bearing seats 401 , thereby ensuring that the transmission mechanism 5 effectively drives the rotation effect of the roller 402 .

[0026] In this embodiment, the Figure 3 The sliding method between the movable cylinder 4 and the support platform 2 shown is that two groups of guide bars 201 are provided on the upper and lower inner walls of the cavity of the support platform 2, and a guide groove 202 is formed between the two groups of guide bars 201. An auxiliary wheel 403 that cooperates with the guide groove 202 is provided on the bearing seat 401 at the end of the movable cylinder 4. This arrangement can ensure that the movable cylinder 4 will not produce abnormal noise due to hard friction when the support platform 2 is displaced, and it can also save effort to make it displace.

[0027] Embodiment 2: The sliding mode between the movable cylinder 4 and the support platform 2 in the embodiment 2 is improved on the basis of the above embodiment. The technical contents disclosed in the above embodiment are not described repeatedly, and the contents of the above disclosed embodiment also belong to the contents disclosed in the embodiment 2.

[0028] One embodiment of the present invention, in combination with Figure 4 The sliding mode between the movable cylinder 4 and the support platform 2 shown is that the upper and lower inner walls of the cavity of the support platform 2 are provided with guide rails 203, and the bearing seat 401 at the end of the movable cylinder 4 is provided with a slider 404 that cooperates with the guide rails 203. This sliding mode is roughly the same as that of the first embodiment, but it will be smoother during the displacement process. However, this method occupies space when setting up, and the subsequent maintenance cost after damage is high.
