Description

Technical Field

[0001] This utility model relates to the field of rubber mixing mill technology, and in particular to an automatic scraping rubber mixing mill. Background Technology

[0002] Rubber products, such as rubber bearings and rubber pads, require their raw materials to be processed through a rubber open mill during the production process. The rubber compound is squeezed and sheared by the relative rotation of two rollers to achieve uniform mixing and plasticization. It is one of the key pieces of equipment in the rubber processing process.

[0003] Currently, traditional rubber open mills are equipped with scrapers at the extrusion rollers to clean the rollers after rubber processing. However, these scrapers generally cannot adjust the gap between the two rollers and cannot adapt to rubber raw materials of different thicknesses and hardnesses, resulting in poor applicability and inability to guarantee processing results. Therefore, it is necessary to propose an automatic scraping rubber open mill to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic rubber scraping open mill with adjustable spacing between two rollers, which enables the processing of rubber of different thicknesses and improves its applicability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic rubber extrusion mill, comprising a base, two symmetrically fixed plates fixedly mounted on the top of the base, an adjustable extrusion assembly disposed between the two fixed plates, a scraper structure disposed on the adjustable extrusion assembly, a rinsing structure disposed on the top between the two fixed plates, the adjustable extrusion assembly comprising two U-shaped frames symmetrically slidably disposed on the base, a screw component for controlling the distance between the two U-shaped frames disposed inside the base, a first motor mounted on one side of the U-shaped frame, and an extrusion roller mounted on the output end of the first motor.

[0006] By adopting the above technical solution, the rubber extrusion roller is driven to rotate by the first motor, which can extrude the rubber. The distance between the two rubber extrusion rollers can be adjusted by the screw component, so as to meet the processing of rubber of different thicknesses. The rubber adhering to the rubber extrusion roller is scraped off by the scraper structure. When a lot of rubber is adhering to the scraper, it can be washed by the flushing structure to maintain better cleaning performance.

[0007] A further feature of this invention is that the fixing plate has a groove for the two extrusion rollers to slide left and right, and the base has openings on both the left and right sides for the U-shaped frame to slide.

[0008] By adopting the above technical solution, the opening allows the U-shaped frame to move stably, and the groove allows the extrusion roller to slide, thereby adjusting the distance between the two.

[0009] A further feature of this invention is that the lead screw component includes a second motor mounted on the right side of the base, the output end of the second motor is equipped with a bidirectional lead screw threadedly connected to two U-shaped frames, and two guide rods slidably connected to the U-shaped frames are mounted on the inner side of the base.

[0010] By adopting the above technical solution, the second motor drives the bidirectional lead screw to rotate, and under the limit of the guide rods on both sides, the U-shaped frames on both sides slide relative to each other, thereby adjusting their spacing.

[0011] A further feature of this invention is that the scraper structure includes two vertical rods fixed to the inner side of the U-shaped frame, and a scraper close to the extrusion roller is installed at the top between the two vertical rods.

[0012] By adopting the above technical solution, the scraper always stays in contact with the surface of the extrusion roller when the U-shaped frame moves, and the surface of the extrusion roller can be cleaned when it rotates.

[0013] A further feature of this invention is that a receiving trough located directly below the two extrusion rollers is fixedly installed on the top of the base.

[0014] By adopting the above technical solution, the processed and cleaned rubber can fall onto the receiving trough. Due to the inclined setting of the receiving trough, it can be automatically conveyed and collected.

[0015] A further feature of this invention is that the rinsing structure includes a connecting frame fixed at the top between two fixed plates, an electric actuator is fixedly installed at the upper end of the connecting frame, a movable plate is installed at the output end of the electric actuator, a plurality of nozzles are equidistantly arranged at the bottom of the movable plate, a water supply pipe connecting the plurality of nozzles is installed at one end of the movable plate, and the other end of the water supply pipe is connected to an external water inlet structure.

[0016] By adopting the above technical solution, the water inlet structure consists of an external water pump and a water tank. When the water pump is driven, the water in the water tank can be sent to the nozzle through the water delivery pipe. The nozzle is then pushed down to the scraper position by the electric push rod, thereby cleaning it.

[0017] A further feature of this invention is that limiting rods that are slidably connected to the connecting frame are fixedly installed on both sides of the top of the movable plate.

[0018] By adopting the above technical solution, the setting of the limit rod makes the sliding of the moving plate more stable and reliable.

[0019] A further feature of this invention is that a controller is fixedly installed at the end of the fixing plate on the right side.

[0020] By adopting the above technical solution, the controller can operate the equipment, making equipment control more convenient.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model uses a second motor to drive a bidirectional lead screw to rotate. Under the limitation of the guide rods on both sides, the U-shaped frame on both sides slides relative to each other, thereby adjusting their spacing and changing the spacing between the two extrusion rollers. The extrusion rollers are driven to rotate by a first motor, which can extrude rubber, thereby enabling the processing of rubber of different thicknesses.

[0023] 2. In this utility model, when the U-shaped frame moves, the scraper always stays in contact with the surface of the extrusion roller. When the extrusion roller rotates, it can clean its surface. Water from the water tank is sent to the nozzle by the water supply pipe. The nozzle is pushed down to the scraper position by the electric push rod, so that it can be rinsed clean and maintain better cleaning performance. Attached Figure Description
