Description

Technical Field

[0002] Silicone pressure-sensitive adhesive is a high-quality pressure-sensitive adhesive with a wide range of uses. It has excellent high-temperature resistance, weather resistance, chemical resistance and electrical properties. It is widely used in automobile manufacturing, shipbuilding, electrical insulation of generators and motors, shielding protection in the manufacturing process of printed circuit boards, and aerospace. Adding tackifiers to silicone pressure-sensitive adhesives improves the adhesion between the silicone and the substrate, thereby improving the use effect of silicone pressure-sensitive adhesives.

[0003] According to patent number CN215464085U, a silicone pressure-sensitive adhesive stirring device is disclosed, comprising a body and a motor, wherein the body comprises a stirring chamber, the surface of the stirring chamber is fixedly connected to the motor, the inner side of the stirring chamber is connected to a stirring rod, the inner side of the stirring chamber is provided with a disassembly mechanism, the disassembly mechanism comprises a support plate, the inner side of the stirring chamber is fixedly connected to the support plate, the surface of the support plate is fixedly connected to a fixing rod, and the inner side of the support plate is provided with a fixing groove. The connection angle and position of the utility model in the fixing groove are changed to facilitate the horizontal sliding of the telescopic rod in the fixing groove. Under the action of the fixing groove, the stirring rod can be quickly disassembled in the stirring chamber, and the surface thereof can be easily cleaned. The rotation of the rotating sleeve facilitates the change of the position of the ring in the sliding sleeve, thereby facilitating the fixing of the sliding sleeve and the cross bar on the stirring rod.

[0004] However, during the implementation of the above solution, when removing the stirring component in the machine body, personnel need additional practical tools to remove the machine cover, which is a time-consuming and labor-intensive operation. Since the pressure-sensitive adhesive is relatively viscous, the above stirring component also requires a higher-power motor to operate when stirring, which consumes a lot of energy. In addition, in the above solution, the pressure-sensitive adhesive is also prone to accumulation at the bottom of the machine body, resulting in the pressure-sensitive adhesive being easily stirred and mixed or sticking and lumping at the bottom of the machine body, making it difficult to discharge the material.

The operation of the dual-axis motor causes the first and second rotating shafts at both ends to rotate together.

[0027] S2: The rotation of the second rotating shaft drives each first connecting plate and each second connecting plate to rotate, so that each connecting rod and each scraper frame rotate in the mixing frame. The gear is engaged with the inner gear ring, so that the gear rotates on the inner gear ring, so that the connecting rod and the spiral blade rotate together between the mixing frame and the heating sleeve, further fully stirring the pressure-sensitive adhesive in the mixing frame.

Since the rotating rod and the vibration mechanism are rotationally connected, the lifting and stirring mechanism on the machine cover is in a vertical state, so as to facilitate the cleaning of the lifting and stirring mechanism without the need for manual removal of the machine cover.

[0031] (3) Beneficial effects

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1.

After the lifting and stirring mechanism is completely separated from the machine body, the operation of the second electro-hydraulic push rod is then started, which will push the first electro-hydraulic push rod to swing, so that the machine cover and the vibration mechanism can swing through the rotating rod. Since the rotating rod and the vibration mechanism are rotationally connected, the lifting and stirring mechanism on the machine cover is in a vertical state, so as to facilitate the cleaning of the lifting and stirring mechanism without the need for manual removal of the machine cover.

[0034] 2. The present invention is provided with a lifting and stirring mechanism, a heating sleeve, a mixing frame and a discharging mechanism. The operation of the double-axis motor causes the first rotating shaft and the second rotating shaft at both ends to rotate together. Under the rotation of the first rotating shaft, it can be lifted and lowered back and forth on the positioning plate, further driving the double-axis motor to move up and down in the mounting cylinder. The rotation of the second rotating shaft will drive each first connecting plate and each second connecting plate to rotate, so that each connecting rod and each scraper frame rotate in the mixing frame. Through the engagement of the gear and the inner gear ring, the gear rotates on the inner gear ring, so that the connecting rod and the spiral blade rotate together between the mixing frame and the heating sleeve, further fully stirring the pressure-sensitive adhesive in the mixing frame, and when the scraper frame moves in the mixing frame, the pressure-sensitive adhesive on the inner wall of the mixing frame and the surface of the heating sleeve is scraped off, so as to avoid the pressure-sensitive adhesive from continuously adhering to the inner wall of the mixing frame and the surface of the heating sleeve, thereby saving energy consumption in stirring the pressure-sensitive adhesive.

[0035] 3. The present invention can scrape off the pressure-sensitive adhesive on the inner wall of the machine body through the setting of the scraping and stirring mechanism, and the stirring rod can also accelerate the flow rate of the pressure-sensitive adhesive at the bottom of the machine body, so that the pressure-sensitive adhesive can be better discharged out of the machine body.
