[0002] Internal mixers are mainly used for the plasticating and mixing of rubber. An internal mixer is a machine that is provided with a pair of rotors with specific shapes and rotating relatively, and intermittently plasticates and mixes polymer materials in a closed state with adjustable temperature and pressure. It mainly consists of an internal mixing chamber, rotors, rotor sealing devices, feeding and pressing devices, discharging devices, transmission devices, machine bases and other parts. Currently, an internal mixer is provided with a feeding port at the upper front part of its equipment, and an electrically controlled flap feeding door is installed at the feeding port. After the flap feeding door is flipped, it can be used as a feeding slide plate. However, the height of the feeding port from the ground is still relatively high. When feeding manually, the material needs to be transported and moved to the flap feeding door to achieve feeding. Therefore, it is necessary to design a device that is convenient for feeding to reduce the labor intensity of workers. Summary of the Invention

[0029] See Figure 1 As shown, the length of the material cylinder 231 is not greater than the width of the flap feeding door 11. The two cover plates 232 on the material cylinder 231 are abutted against each other, and the outer walls of the cover plates 232 and the outer wall of the material cylinder 231 are within the same cylindrical surface.

[0030] See Figure 2 As shown, the sliding plate 2321 on the cover plate 232 is circular, and the outer wall of the sliding plate 2321 and the outer wall of the material cylinder 231 are within the same cylindrical surface; the central axes of the driving shaft 221, the driving disc 22, and the material cylinder 231 are on the same straight line.

[0031] See Figure 2 As shown, there are at least three connecting columns 233 on the sliding plate 2321.

[0032] See Figure 5 As shown, a wire passing hole 222 opposite to the electromagnet 236 is formed in the center of the driving shaft 221.

[0033] After the electromagnet 236 is powered off, it attracts the permanent magnet block 234, and after the electromagnet 236 is powered on, it repels the permanent magnet block 234.

[0034] See Figure 5 As shown, the climbing seat 244 is sleeved on the outside of the rack 25 and the frame 2112. A guiding block 2441 is formed at the upper end of the climbing seat 244, and the guiding block 2441 abuts against the upper end face of the frame 2112; the end of the driving shaft 221 is connected to the climbing seat 244 through a bearing.

[0035] See Figure 1 、 2 As shown in Figure 3, protective covers 26 are fixed on both sides of the upper machine base 21 of the feeding device 2. The side vertical plates 211, the climbing assembly 24, and the rack 25 are all inserted into the protective covers 26; avoiding notch openings 261 opposite to the cover plates 232 are respectively formed on the inner sides of the upper and lower ends of the protective cover 26; the radius of the outer wall of the material cylinder 231 and the radius of the driving disc 22 are both smaller than the center distance from the inclined plane on the side vertical plate 211 to the center of the driving disc 22.

[0036] See Figure 1As shown in the figure, a dust suction hood 3 is provided above the front of the main machine 1. The dust suction hood 3 is located above the flap feeding door 11. A rubber sealing strip 31 is fixed around the lower side of the dust suction hood 3. The dust suction hood 3 can be used to absorb the pungent smell escaping from the feeding port during the mixing process of the internal mixer.

[0037] An installation frame is fixed to the bottom of the main machine 1. A socket 2113 opposite to the installation frame is formed at the rear side of the side vertical plate 211.

[0038] Working principle: The present invention is an internal mixer with an electric feeding device assembled therein. The technical point of the internal mixer is located on the feeding device 2. The feeding device 2 is similar to a climbing type elevator, but there are differences from the elevator. The differences lie in the climbing component 24 and the loading cylinder component 23. The climbing component 24 and the loading cylinder component 23 are specifically designed for the flap feeding door 11 on the internal mixer. The climbing component 24 is mainly driven by a motor 245, and the climbing of the loading cylinder component 23 is achieved by gear transmission. During the climbing process of the loading cylinder component 23, it can rotate by itself. Based on the precise control of gear transmission and the self-rotation of the loading cylinder component 23, it can be realized that the loading port 2311 on the loading cylinder component 23 faces upward at the lower part of the feeding device 2, and when it moves to the upper part of the feeding device 2, the loading port 2311 faces downward, so that the material can fall on the opened flap feeding door 11.

[0039] During specific feeding, as Figure 2 shown in the figure, when the loading cylinder component 23 is at the lower part of the feeding device 2, the electromagnet 236 is started. By the repulsion between the electromagnet 236 and the permanent magnet block 234, the cover plate 232 on the cylinder 231 is opened, and materials are filled into the cylinder 231 from the loading port 2311 of the cylinder 231. Then the electromagnet 236 is powered off, and the cover plate 232 is manually closed. The motor 245 on the climbing component 24 is started, and the climbing component 24 drives the cylinder 231 to move to the upper rear of the feeding device 2. Then the flap feeding door 11 on the internal mixer is started, and the flap feeding door 11 is flipped to the lower layer of the cylinder 231. At this time, the electromagnet 236 is powered on again, the cover plate 232 will be opened, and the materials will come out from the loading port 2311 and fall on the flap feeding door 11, and enter the internal mixer along the flap feeding door 11; after discharging, the flap feeding door 11 is reset, and then it can be manually closed or not closed, and the climbing component 24 is started to move the cylinder 231 downward; thus, the next feeding can be carried out.

[0040] The above embodiments are used to illustrate the present invention by way of example, rather than to limit the present invention. Any person skilled in the art can modify the above embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of the patent protection of the present invention shall be as set forth in the claims of the present invention.
