[0024] like Figure 1-4As shown, a mixing device for one-component silicone rubber includes a mixing box 1, the mixing box 1 includes a box body 101, an adsorption device 102 is installed on one side of the top of the box body 101, an inlet 104 is installed on the other side of the top of the box body 101, a water cooling device 103 is buried inside the shell of the box body 101, a discharge port 105 is opened at the bottom of the box body 101, a stirring component 2 is arranged inside the box body 101, the stirring component 2 includes an arc scraper 209, a disassembly component 3 is arranged at the bottom of the arc scraper 209, and the disassembly component 3 includes a connecting shell 301, a spiral blade tube 302 is arranged below the connecting shell 301, a connecting block 304 is fixedly connected to the top of the spiral blade tube 302, and the spiral blade tube 302 is fixedly connected to the top of the spiral blade tube 304. The inner part of the spiral blade tube 302 is slidably connected with an inner rod 305, and the top end of the inner rod 305 penetrates into the connecting block 304, and the connecting block 304 is engaged and connected with the connecting shell 301; through the inner rod 305 pushing column 307, cooperating with the clamping block 309 and the clamping groove 308, the spiral blade tube 302 can be directly disassembled for cleaning or replacement after long-term use, so that the spiral blade tube 302 can be kept clean, and it is avoided that the spiral blade tube 302 is stuck with too much material after long-term use, resulting in clogging of the discharge port 105, thereby reducing the discharge efficiency; and when disassembling, it is only necessary to push the inner rod 305 upwards, and when installing, it is only necessary to insert the connecting block 304 into the connecting shell 301, which is simple to operate.

[0025] The inner rod 305 passes through the bottom end of the spiral blade tube 302, and a plastic sleeve 303 is provided on the outer side of the bottom end of the inner rod 305, and the plastic sleeve 303 is adhered to the bottom end of the spiral blade tube 302; the plastic sleeve 303 is made of polystyrene, which can protect the inner rod 305 and the bottom end of the spiral blade tube 302 from being adhered by sticky materials, causing the assembly and disassembly component 3 to malfunction, and the plastic sleeve 303 is easy to crush, and the fragments are not lethal, so it is relatively safe.

[0026] The top of the inner rod 305 is symmetrically connected to a telescopic spring 306, and the other ends of the two telescopic springs 306 are respectively connected to a push column 307, which passes through both sides of the connecting block 304;

[0027] A card slot 308 is provided on the top side of the connecting block 304, and a card block 309 is connected to the card slot 308 by a buckle.

[0030] An arc scraper rod 209 is fixedly connected between the two arc scrapers 207. The arc scraper rod 209 fits the bottom of the box body 101.

A push plate 212 is fixedly connected to the side of the sliding sleeve 211; the length of the push plate 212 is greater than the distance between the two wave peaks of the corrugated groove 210. The push plate 212 pushes the raw materials at the bottom of the box body 101 into the discharge port 105 during the movement.

[0031] The working principle of this utility model:

[0032] When the utility model is working, the driving gear 202 is first started, and the driving shaft 204 is rotated through the driving gear 202 and the rotating gear 203, so that the fan blade 205 and the arc scraper 207 are rotated, so that the raw materials in the box body 101 are stirred, and the spiral blade tube 302 is rotated through the arc scraper rod 209, so that the raw materials falling into the discharge port 105 will be turned up, and the arc design of the fan blade 205 and the arc scraper 207 makes the raw materials be turned upward, thereby increasing the stirring efficiency;

[0033] When the spiral leaf tube 302 needs to be replaced, the plastic sleeve 303 is crushed, and the spiral leaf tube 302 is held in the hand, while the inner rod 305 is pushed upward to rotate the telescopic spring 306 and push the push column 307 to extend into the connecting block 304, and the displacement plate 310 is pushed to squeeze the reset spring 311 and move outward, so that the block 309 is disengaged from the slot 308, and then the spiral leaf tube 302 is pulled downward and the inner rod 305 is released and pushed, and finally the spiral leaf tube 302 is disassembled and cleaned, and the plastic sleeve 303 is re-adhered after cleaning, and then the connecting block 304 is inserted into the connecting shell 301, and finally the block 309 is engaged with the slot 308;

[0034] When discharging the material, the motor 201 is reversed so that the fan blades 205 and the arc scraper 207 push the material downward, and while the sleeve 211 slides on the corrugated groove 210, the push plate 212 pushes the material at the bottom of the box body 101 into the discharge port 105.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
