Description

Technical Field

[0001] This utility model relates to the field of silicone rubber production technology, and in particular to a reinforcing agent pretreatment device for silicone rubber production. Background Technology

[0002] Rubber reinforcing agents enhance the mechanical properties of rubber, significantly improving key indicators such as abrasion resistance, tear strength, and tensile strength of the finished product.

[0003] Rubber reinforcing agents are generally in the form of powdered solids. After long-term storage, they will clump together. In order for the rubber reinforcing agent to effectively bond with the rubber, it needs to be preheated. The clumped rubber also needs to be crushed into powder by extrusion. This requires pretreatment of the reinforcing agent. The existing pretreatment method is mainly stirring and heating. During the stirring and heating process, some of the reinforcing agent will clump together on the side of the stirring rod after being squeezed. This results in insufficient amount of reinforcing agent added and it cannot be quickly crushed after stirring and added into the rubber. This process requires multiple steps and is relatively complicated to use. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a pretreatment device for reinforcing agents in the production of silicone rubber.

[0007] In a preferred embodiment of this utility model, one end of the connecting bracket is fixed to the outer side of the bottom of the heating chamber, and the other end is fixed to the inner side of the outer cover.

[0008] The connecting bracket not only facilitates the installation of the baffle plate, but also provides auxiliary fixation for the bottom of the heating chamber, improving the stability of the equipment.

Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0023] like Figure 1-4 The device shown is a pretreatment apparatus for reinforcing agents in silicone rubber production, comprising an outer casing 1, a top cover 2, a motor 3, a feed pipe 4, a cylinder 5, a connecting ring 6, a heating ring 7, a heating chamber 8, a stirring device 9, a connecting bracket 10, and a baffle plate 11. The top cover 2 is installed on the top of the outer casing 1, the motor 3 is installed on the top of the top cover 2, the feed pipe 4 is fixedly connected to the top cover 2, the cylinder 5 is installed on the outside of the outer casing 1, the connecting ring 6 is fixedly installed on the inside of the outer casing 1, the heating ring 7 is fixedly installed at the bottom of the connecting ring 6, the heating chamber 8 is fixedly connected to the inside of the connecting ring 6, and the stirring device 9 is located on the outside of the outer casing 1. Inside the heating chamber 8, the connecting bracket 10 is located at the bottom of the stirring device 9, and the baffle plate 11 is clamped inside one end of the connecting bracket 10. The stirring device 9 includes a connecting pipe 91, a connecting piece 92, a vibrator 93, a stirring rod 94, a scraper 95, a pressure seat 96, and a pressure plate 97. The connecting piece 92 is fixedly located inside the connecting pipe 91, the vibrator 93 is installed on the top of the connecting piece 92, the stirring rod 94 is fixedly connected to the outside of the connecting pipe 91, the scraper 95 is clamped to one end of the stirring rod 94, the pressure seat 96 is fixedly located at the bottom of the connecting pipe 91, and the pressure plate 97 is clamped to the bottom of the pressure seat 96.

[0024] Specifically, one end of the connecting bracket 10 is fixed to the outer bottom of the heating chamber 8, and the other end is fixed to the inner side of the outer cover 1. The bottom of the heating chamber 8 is provided with a screening hole. The upper surface of the baffle plate 11 is attached to the bottom of the heating chamber 8. The connecting bracket 10 has a slot that matches the baffle plate 11. The telescopic end of the cylinder 5 passes through and extends into the inner side of the outer cover 1, and is fixed to the bottom of one end of the baffle plate 11. The top of the stirring rod 94 and the top of the pressure seat 96 are provided with a discharge slope to avoid material accumulation. The scraper 95 and the pressure plate 97 are made of heat-resistant silicone. The end of the scraper 95 is attached to the inner wall of the heating chamber 8, and the pressure plate 97 is attached to the inner bottom of the heating chamber 8. The top of the connecting pipe 91 is provided with a connecting rod. The connecting rod at the end of the connecting pipe 91 is fixed to the output end of the motor 3. One end of the feed pipe 4 passes through the top cover 2 and extends to the inner top of the heating chamber 8.

[0025] In this embodiment, the reinforcing agent powder to be used is first added into the heating chamber 8 through the feed pipe 4. Then, the heating ring 7 is turned on. The heating ring 7 is sleeved on the outside of the heating chamber 8 so that heat can be transferred to the inside of the heating chamber 8. During the heating process, the motor 3 is in the starting state. The connecting pipe 91 is rotated through the connecting rod at the top of the connecting pipe 91, thereby driving the stirring rod 94 to rotate. During the rotation of the stirring rod 94, the scraper 95 at its end scrapes off the powder on the inner wall of the heating chamber 8, so that the reinforcing agent inside can be heated evenly and effectively.

[0026] Furthermore, when the internal reinforcing agent is heated to a suitable temperature and maintained for a certain period of time, the cylinder 5 contracts, and the baffle plate 11 is pulled back in the connecting bracket 10, so that the powder can fall from the bottom sieve hole of the heating chamber 8. Under the pressure of the pressure seat 96 and its bottom pressure plate 97, the caking part will be crushed. At this time, the vibrator 93 installed inside the connecting pipe 91 through the connecting plate 92 is started, so that the stirring rod 94 and the heating chamber 8 will vibrate to a certain extent. This vibration will shake off the powder that is adhered to and squeezed on the surface of the stirring rod 94, and the vibration can make the sieve hole complete the sieve work more quickly, avoiding the caking of the powder due to compression and the blockage of the sieve hole, thereby ensuring the amount of reinforcing agent added and the sieve speed, and reducing the residue of reinforcing agent in the pretreatment equipment.
