Description

Technical Field

[0001] The utility model relates to the technical field of open mixing mills, in particular to an automatic open mixing mill device for silica gel processing. Background Art

[0002] An open rubber mixer has two horizontally arranged rollers, and is a machine that mixes rubber between the two rollers. It is called an open mixer for short. It is mainly composed of rollers, a frame, a distance adjustment device, and a transmission device. The material is pulled into the gap between the two rollers rotating in opposite directions at different linear speeds under the action of friction. The material in the frame is strongly sheared and squeezed through the gap between the rollers, which increases the temperature of the material and the plasticity, thereby achieving the purpose of mixing rubber. It is used for operations such as plastication, mixing, sheeting, and hot mixing.

[0003] When processing silicone, the open mill shears and squeezes the silicone through double rollers. The existing open mill has a relatively simple structure. During the processing of silicone at different times, the distance between the double rollers cannot be adjusted according to the hardness of the silicone itself, which is not convenient for processing silicone with different hardness. In addition, during the processing of the existing open mill, silicone is easy to stick to the surface of the roller, and the existing degumming mechanism is not convenient to adapt to the adjustable roller. Utility Model Content

[0006] When using an automatic refining device for silicone processing in the technical solution, silicone is introduced from the upper end of the device between the two rubber refining rollers, the built-in motor of the side box is started to drive the second screw to rotate, and the second screw thread drive realizes the displacement of the drive box, and the drive box drives the rubber refining roller to move through the turntable, so that the distance between the two rubber refining rollers is reduced. At the beginning of processing, the silicone is in a relatively soft state after production, and the surface has no tension and hardness. Therefore, the distance between the two rubber refining rollers is adjusted to be smaller, which is convenient for shearing processing. The built-in motor of the drive box is started to drive the turntable to rotate, and the turntable drives the corresponding rubber refining roller to rotate. The rapid relative rotation makes the rubber mixing roller process the silicone. Multiple shearing heats and softens the silicone. The plasticity of the silicone increases, and the distance between the two rubber mixing rollers can be gradually controlled to increase to ensure the hardness and plasticity. During the processing, the silicone sticks to the surface of the rubber mixing roller. The built-in motor of the side rail is started to drive the first screw to rotate. The first screw thread drive realizes the horizontal bar displacement. The horizontal bar drives the scraper to displace on the upper side of the rubber mixing roller. When the rubber mixing roller rotates, the silicone sticking to the surface of the rubber mixing roller is scraped off through the scraper fitting design, so that it gathers on the upper side of the two rollers for continuous processing. The scraper slides on the guide rail and can adjust its position with the rubber mixing roller.

The box is placed and supported by the foot pad, and the anti-slip cover increases friction and ensures support stability.

[0008] Preferably, both ends of the box body are provided with assembly openings, and the side box is fixedly installed in the assembly openings by bolts. The assembly openings and bolts are used to realize detachable installation of the side box, which is convenient for later maintenance.

[0009] Preferably, sliders are fixed on the upper and lower sides of the drive box, and a slide groove is provided in the side box, and the slider is slidably installed in the corresponding slide groove. The slider cooperates with the slide groove to make the drive box move more smoothly and limit its position at the same time.

[0010] Preferably, the horizontal bar is longitudinally located on the upper side of the rubber mixing roller, and the two ends of the horizontal bar are slidably mounted in the two side rails. The horizontal bar is slidably mounted between the two side rails.

[0011] Preferably, a first screw rod is rotatably installed in the side rail, and both ends of the first screw rod are provided with positive and negative threads, and both ends of the first screw rod are respectively threaded through the corresponding sliding ends of the horizontal bar. The first screw rod is driven to rotate by the built-in motor of the side rail, and the first screw rod thread drives the two horizontal bars to move relative to each other.

[0012] Preferably, the lower side of the scraper is designed to be arc-shaped, and the arc-shaped opening of the scraper fits with the upper side of the rubber mixing roller. Through the arc-shaped opening, the rubber mixing roller synchronously drives the scraper to move during the displacement process, and the fit is ensured at the same time.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the operator starts the device through an external control device when powered by an external power supply, introduces the silica gel from the upper end of the device to between the two rubber mixing rollers, starts the built-in motor of the side box to drive the second screw to rotate, and the second screw thread drive realizes the displacement of the drive box, and the drive box drives the displacement of the rubber mixing roller through the turntable, so that the distance between the two rubber mixing rollers is reduced.

Therefore, the distance between the two rubber mixing rollers is adjusted to be smaller, which is convenient for shearing processing. The built-in motor of the drive box is started to drive the turntable to rotate, and the turntable drives the corresponding rubber mixing roller to rotate. The relative rotation at different speeds enables the rubber mixing roller to process the silica gel. Multiple shearings heat and soften the silicone, and the plasticity of the silicone increases. The spacing between the two rubber mixing rollers can be gradually controlled to increase, ensuring the hardness and plasticity. During the processing, the silicone sticks to the surface of the rubber mixing roller, and the built-in motor of the side rail is started to drive the first screw to rotate.
