Description

Technical Field

[0001] This utility model relates to tire production, specifically a rubber mixing machine that facilitates waste removal. Background Technology

[0002] Rubber mixing mills are divided into two types: open and closed. Open mills are mainly used for hot refining, sheeting, breaking, plasticizing, and mixing of rubber. Closed mills are mainly used for plasticizing and mixing rubber, and they have an additional mixing chamber compared to open mills. Rubber mixing mills are mainly used in rubber-related industries such as reclaimed rubber plants, transmission belt plants, conveyor belt plants, rubber product plants, shoe factories, cable factories, hose factories, and sealing parts factories.

[0003] Publication (Announcement) No.: CN220162924U discloses a rubber mixing mill for easy waste removal, comprising: a rubber mixing mill body, a U-shaped frame installed on the top of the rubber mixing mill body, a collection component installed on the inner bottom of the rubber mixing mill body, a scraping component and a telescopic rod assembly for driving the scraping component to move up and down installed on the U-shaped frame, the scraping component including a U-shaped scraper, and rubber removal mechanisms symmetrically arranged on both sides of the U-shaped scraper. This utility model, through the cooperation of the U-shaped scraper and the telescopic rod assembly, uses an electric push rod to drive the U-shaped scraper downwards, so that its ends contact the heating rollers on the rubber mixing mill body respectively. That is, when the rollers on the rubber mixing mill body rotate in opposite directions, the U-shaped scraper can scrape off the rubber material from the surfaces of the two heating rollers respectively.

[0004] However, research has revealed that this technical solution still has at least the following drawbacks: In the above-mentioned device, the rubber material on the surface of the heating roller is scraped off by a U-shaped scraper, and the residual rubber material on the surface of the U-shaped scraper is removed by an L-shaped cleaning plate. However, the residual rubber material on the surface of the U-shaped scraper has a strong adhesive property, and it is difficult to completely remove the residual rubber material by simply manually pushing the L-shaped cleaning plate across the surface of the U-shaped scraper. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a rubber mixing machine that facilitates waste removal. This machine can thoroughly remove adhering residual rubber materials and features good removal effect and high removal efficiency.

[0006] The technical solution of this utility model is: a rubber mixing machine that is easy to clean waste, including a rubber mixing machine body, a set of heating rollers on the rubber mixing machine body, a horizontally arranged top plate connected to the top of the rubber mixing machine body through a set of columns, a vertically arranged cylinder in the middle of the top plate, and a horizontally arranged lifting platform connected to the moving end of the cylinder.

[0007] The bottom of the lifting platform is symmetrically provided with scraper blades on both sides for scraping the surface of the heating roller. A lead screw is rotatably connected to the lifting platform between the two scraper blades. A handwheel is installed at the end of the lead screw, and a sliding plate is threaded onto the lead screw.

[0008] Both ends of the sliding plate are connected to heat-conducting cleaning plates that slide in contact with the outer surface of the scraper plate via guide frames. The heat-conducting cleaning plates have cavities inside, and heating tubes are installed inside the cavities.

[0009] Preferably, the lifting platform is provided with a set of guide grooves, the guide frame passes through the guide grooves, and the guide frame is slidably connected to the guide grooves.

[0010] Preferably, the column is provided with a vertically arranged lifting groove, and a lifting rod is slidably connected in the lifting groove, with the free end of the lifting rod fixedly connected to the lifting platform.

[0011] Preferably, a material collection box is provided below the heating roller.

[0012] Preferably, the material collection box is slidably provided with a pusher plate, and a pusher frame is provided on one side of the pusher plate. The pusher frame extends out of the material collection box and is slidably connected to the material collection box.

[0013] Compared with the prior art, this utility model has the following advantages: This utility model can scrape off the residual rubber adhering to the surface of the heating roller through the liftable scraper, so as to clean the outer surface of the heating roller. When some rubber material adheres to the scraper, the scraper is heated by heat conduction through the heat-conducting cleaning plate, and then scraped off by moving the heat-conducting cleaning plate. The residual rubber, which becomes soft after heating, is easily scraped off by the heat-conducting cleaning plate, which helps to completely remove the residual rubber material and improves the removal effect of the residue.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0019] like Figures 1 to 3 A rubber mixing mill that facilitates waste removal includes a rubber mixing mill body 5, and a set of heating rollers 4 are provided in the middle of the rubber mixing mill body 5.

[0020] The top of the rubber mixing machine body 5 is connected to a horizontally arranged top plate 2 by four columns 3. A vertically arranged cylinder 1 is provided in the middle of the top plate 2. A through hole is opened on the top plate 2. The moving end of the cylinder 1 passes through the through hole and is connected to a horizontally arranged lifting platform 9.

[0021] The lifting platform 9 consists of a rectangular frame and a platform mounted on the frame. A pair of vertically arranged scraper blades 17 are symmetrically installed on both sides of the bottom of the lifting platform 9. The bottom of the scraper blades 17 is provided with inclined blades, which scrape off the adhesive residue on the surface of the heating roller 4.

[0022] A lead screw 12 is located on the lifting platform 9 between the two scraper blades 17. The lead screw 12 is rotatably connected to the frame of the lifting platform 9. A handwheel 13 is installed at one end of the lead screw 12. Rotating the handwheel 13 will drive the lead screw 12 to rotate.

[0023] A sliding plate 18 is threaded onto the lead screw 12. Both ends of the sliding plate 18 are connected to a heat-conducting adhesive removal plate 11 via a guide frame 16. The inner side of the heat-conducting adhesive removal plate 11 slides in contact with the outer surface of the scraper plate 17, and the heat-conducting adhesive removal plate 11 scrapes away the residual adhesive adhering to the outer surface of the scraper plate 17.

[0024] The heat-conducting adhesive removal plate 11 is made of heat-conducting material. The heat-conducting adhesive removal plate 11 has a cavity inside, and a heating tube 19 for heating the heat-conducting adhesive removal plate 11 is installed inside the cavity. The heat from the heating tube 19 can be transferred to the scraper plate 17 through the heat-conducting adhesive removal plate 11.

[0025] Working principle:

[0026] When the heating roller 4 on the rubber mixing mill body 5 needs to be cleaned, the control cylinder 1 extends to make the lifting platform 9 drive the scraper 17 to move downward until the bottom blade of the scraper 174 contacts the top side surface of the heating roller 4. Then the heating roller 4 is started to rotate, and the scraper 17 is used to scrape off the residual rubber adhering to the surface of the heating roller 4.

[0027] When some residual adhesive cannot fall off and adheres to the outer surface of the scraper 17, the heating tube 19 is activated to heat the heat-conducting adhesive removal plate 11, and the heat-conducting adhesive removal plate 11 heats the scraper 17, making the residual adhesive on the scraper 17 soft. Then, the handwheel 13 is turned to drive the lead screw 12 to rotate. The sliding plate 18, which is threaded to the lead screw 12, drives the heat-conducting adhesive removal plate 11 to move through the guide frames 16 on both sides to scrape off the residual adhesive adhering to the scraper 17.

[0028] This invention utilizes a liftable scraper 17 to remove residual adhesive adhering to the surface of the heating roller 4, thus cleaning the outer surface of the heating roller 4. When some adhesive adheres to the scraper, the scraper 17 is heated by the heat-conducting cleaning plate 11 through heat conduction. Then, the scraper is cleaned by moving the heat-conducting cleaning plate 11. The residual adhesive, softened by heating, is easily scraped off by the heat-conducting cleaning plate 11, thereby facilitating the thorough removal of residual rubber material and improving the removal effect. Example 2

[0029] This embodiment is a further optimization based on the above embodiment, specifically:

[0030] like Figures 1 to 3 The lifting platform 9 is provided with a set of guide slides 10, and the guide frame 16 passes through the guide slides 10. The guide frame 16 is slidably connected to the guide slides 10. Through the sliding cooperation between the guide frame 16 and the guide slides 10, the heat-conducting cleaning plate 11 moves more stably and smoothly.

[0031] The column 3 is provided with a vertically arranged lifting groove 15, and a lifting rod 14 is slidably connected in the lifting groove 15. The free end of the lifting rod 14 is fixedly connected to the lifting platform 9. The lifting groove 15 and the lifting rod 14, which are slidably connected, make the lifting platform 9 rise and fall more stably and smoothly. Example 3

[0032] This embodiment is a further optimization based on the above embodiment, specifically:

[0033] like Figure 1 A collection box 8 is provided below the heating roller 4. The collection box 8 is used to hold some of the rubber material that falls off the heating roller 4 when the rubber mixing machine body 5 is working, as well as the residual rubber that falls off when cleaning the heating roller 4 and the scraper 17.

[0034] The material collection box 8 is slidably equipped with a pusher plate 7. A pusher frame 6 is provided on one side of the pusher plate 7. The pusher frame 6 extends out of the material collection box 8 and is slidably connected to the material collection box 8. When the material collection box 8 contains some adhesive, the operator controls the pusher frame 6 to move, so that the pusher frame 6 drives the pusher plate 7 to push the adhesive in the material collection box 8 to one side of the material collection box 8 and squeeze it into a block, which occupies less space.

[0035] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
