Therefore, it is very important to understand the research and development direction, equipment, technology and trends of rubber granule production technology at home and abroad for improving the technical specifications of rubber granules and enhancing market competitiveness. Rubber granules are mainly produced through the processing of various waste rubber raw materials including waste rubber, tourist shoe soles, scraps, cable skins, rubber scraps, car mats, etc. Generally, manufacturers will add curing agents and other raw materials to the rubber granules to improve the bonding strength.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0020] like Figure 1-3 As shown, the present application provides a high-efficiency mixer for synthetic rubber composite materials, which is provided with a premixing chamber 1 and a mixing chamber 2. A premixing component is provided in the premixing chamber 1, and the premixing component is connected to the power component. The premixing component includes a first rotating shaft 3 and a second rotating shaft 4, and the first rotating shaft 3 and the second rotating shaft 4 are rotatably connected to the premixing chamber 1. A plurality of stirring blocks 5 are connected to the first rotating shaft 3 and the second rotating shaft 4. A plurality of filter holes 6 are provided on the bottom side wall of the premixing chamber 1. A mixing component is provided in the mixing chamber 2, and the mixing component includes a mixing motor 7. The output end of the mixing motor 7 is connected to a third rotating shaft 8, and a mixing block 9 is connected to the third rotating shaft 8. The outer walls of the premixing chamber 1 and the mixing chamber 2 are both connected to temperature control devices.

[0021] In the technical solution adopted in this embodiment, the rubber raw materials can be pre-mixed by setting up a pre-mixing chamber 1. It should be noted that a feed port is provided at the top of the pre-mixing chamber 1, and a discharge port is provided at the bottom of the mixing chamber 2. The rubber raw materials are added to the pre-mixing chamber 1 from the feed port, and the power component is driven to rotate by the power component to pre-mix the rubber raw materials. Specifically, the power component drives the first rotating shaft 3 and the second rotating shaft 4 to rotate, thereby driving multiple stirring blocks 5 to rotate together, and pre-mixing the rubber raw materials in the pre-mixing chamber 1. The pre-mixed rubber raw materials pass through several filter holes 6 and enter the mixing chamber 2. The third rotating shaft 8 is driven to rotate by the mixing motor 7, thereby driving the mixing block 9 to rotate, and further mixing the rubber raw materials, thereby ensuring the mixing quality of the rubber raw materials. The temperature control device can control the temperature in the pre-mixing chamber 1 and the mixing chamber 2, thereby preventing the temperature in the pre-mixing chamber 1 and the mixing chamber 2 from being too high, resulting in the production of by-products during the mixing process.

[0022] Furthermore, in this embodiment, the power assembly includes a premixing motor 10 and a guide wheel device 11 , and the premixing motor 10 is cooperatively connected to the guide wheel device 11 , the first rotating shaft 3 , and the second rotating shaft 4 via a chain 12 .

[0023] In the technical solution adopted in this embodiment, the power component is specifically powered by a premixing motor 10. The premixing motor 10 is connected to the first rotating shaft 3 and the second rotating shaft 4 through a chain 12, driving the first rotating shaft 3 and the second rotating shaft 4 to rotate together, thereby realizing the premixing of the rubber raw materials. The guide wheel device 11 is provided to tension and guide the chain 12.

[0024] Furthermore, in this embodiment, the stirring block 5 is adjustably connected to the first rotating shaft 3 and the second rotating shaft 4 , and the distance between the stirring block 5 and the inner wall of the premixing chamber 1 is adjustable.

[0025] In the technical solution adopted in this embodiment, the adjustable connection between the stirring block 5 and the first rotating shaft 3 and the second rotating shaft 4 is specifically a threaded fitting connection. By controlling the threaded fitting depth between the stirring block 5 and the first rotating shaft 3 and the second rotating shaft 4, the distance between the stirring block 5 and the inner wall of the premixing chamber 1 is adjusted. It should be noted that in the process of premixing the rubber raw materials, there will be a phenomenon of rubber raw material agglomeration, which affects the mixing efficiency of the rubber raw materials. By adjusting the distance between the stirring block 5 and the inner wall of the premixing chamber 1, rubber raw material particles of different sizes can be extruded as needed, thereby reducing the number of raw material particles in the premixing chamber 1 and improving the mixing efficiency of the raw materials.

[0026] Furthermore, in this embodiment, the temperature control device is a cooling pipe, and the cooling pipe is wound around the outer walls of the premixing chamber 1 and the mixing chamber 2.

[0027] In the technical solution adopted in this embodiment, a temperature control device is provided to control the temperature in the premixing chamber 1 and the mixing chamber 2, thereby preventing the temperature in the premixing chamber 1 and the mixing chamber 2 from being too high, which leads to the production of by-products during the mixing process. Specifically, a cooling pipe is provided and a coolant is introduced into the cooling pipe to reduce the temperature in the premixing chamber 1 and the mixing chamber 2.

[0028] Furthermore, in this embodiment, a controller is provided, temperature sensors 13 are provided in the premixing chamber 1 and the mixing chamber 2, an electrically controlled valve is provided on the cooling pipe, and the controller is electrically connected to the temperature sensor 13 and the electrically controlled valve.

[0029] In the technical solution adopted in this embodiment, the temperature in the premixing chamber 1 and the mixing chamber 2 can be monitored by providing a temperature sensor 13. The temperature sensor 13 can also transmit a temperature signal to the controller. When the controller receives an overtemperature signal from the temperature sensor 13, the controller controls the electronically controlled valve to open and introduce coolant into the cooling pipe, thereby realizing automatic regulation of the temperature of the premixing chamber 1 and the mixing chamber 2.

[0030] The principle of the present utility model is as follows: the rubber raw material is put into the premixing chamber 1 through the feed port, the premixing motor 10 is started, the premixing motor 10 drives the first rotating shaft 3 and the second rotating shaft 4 to rotate through the chain 12, thereby driving the stirring block 5 to rotate, and the rubber raw material is premixed. The stirring block 5 and the inner wall of the premixing chamber 1 act together to squeeze the rubber raw material particles, thereby reducing the number of rubber raw material particle agglomerates. The premixed rubber raw material passes through the filter hole 6 and enters the mixing chamber 2. The mixing motor 7 drives the third rotating shaft 8 to drive the mixing block 9 to rotate, and the rubber raw material is further mixed, thereby ensuring the mixing quality of the rubber raw material.

[0031] The utility model provides a premixing chamber 1 and a mixing chamber 2, and cooperates with a premixing component and a mixing component to premix the rubber raw materials. During the premixing process, the distance between the stirring block 5 and the inner wall of the premixing chamber 1 is adjustable, so that the agglomerated rubber raw material particles are squeezed, the number of agglomerated rubber raw material particles is reduced, and thus the mixing efficiency of the rubber raw materials is improved. By providing a temperature control device, a temperature sensor 13 and a controller, the temperature in the premixing chamber 1 and the mixing chamber 2 is monitored and controlled, so as to prevent the temperature in the premixing chamber 1 and the mixing chamber 2 from being too high, which would lead to the generation of by-products in the mixing process, thereby ensuring the quality of the mixed rubber.
