[0002] In the field of rubber product manufacturing, rubber compounding is a crucial process, and its quality directly affects the final performance of rubber products. Rubber compounding mainly involves uniformly mixing raw rubber with various ingredients under mechanical action.

[0003] Currently, common rubber mixing equipment suffers from numerous inconveniences in the feeding process: traditional mixing equipment typically requires manual transport of materials to the top of the mixing device for feeding, or a simple feeding platform where materials are manually lifted to a certain height and poured into the mixing device. This feeding method is labor-intensive and inefficient. Therefore, we have made improvements and proposed a new mixing equipment for rubber mixing. Utility Model Content

[0033] Furthermore, the stirring component includes a rotating shaft 103 mounted in the mixing chamber 102 via a bearing. The outer surface of the rotating shaft 103 is fixedly connected to a stirring blade 104 located in the mixing chamber 102. During the rotation of the stirring blade 104, the raw materials in the mixing chamber 102 can be stirred.

[0034] Furthermore, a protective box 106 is provided on the side of the mixing tank 102, one end of the rotating shaft 103 extends to the outside of the mixing tank 102, a motor 105 is provided on the first frame 101, and sprockets located inside the protective box 106 are provided on the output shaft of the motor 105 and the outer surface of the rotating shaft 103, and a chain is provided between the two sprockets. The motor 105 can drive the rotating shaft 103 to rotate through the chain and sprockets, thereby driving the mixing blades 104 to rotate.

[0035] Furthermore, a protective cover 115 is hinged to the top of the mixing tank 102, and a handle is installed on the protective cover 115. The protective cover 115 is used to protect the top of the mixing tank 102.

[0036] Furthermore, a discharge port 107 is provided on the side of the mixing tank 102 away from the protective box 106. A baffle 108 is installed on the side of the mixing tank 102 near the discharge port 107 via a hinge. A fixing member is provided between the baffle 108 and the mixing tank 102. The discharge port 107 is used to discharge the raw materials after mixing in the mixing tank 102, while the baffle 108 is used to block the discharge port 107.

[0037] Furthermore, the fasteners include a threaded opening 109 on the mixing tank 102 and an internally threaded pipe 111 fixedly connected to the mixing tank 102. A hand-tightening bolt 110 is inserted and connected to the baffle 108, and the hand-tightening bolt 110 is threadedly connected to the inner wall of the threaded opening 109. The hand-tightening bolt 110 and the threaded opening 109 cooperate to fix the position of the baffle 108.

[0038] Furthermore, a transfer box 112 is fixedly connected to the first frame 101. The transfer box 112 is located below the discharge port 107, and a discharge port 113 is opened on the outside of the transfer box 112.

[0041] When using, refer to Figure 1 The raw materials are poured into the feeding hopper 204, and then conveyed by the auger conveyor 203 to the discharge pipe 205. From there, the raw materials fall into the mixing tank 102, where they are stirred by the mixing blades 104. After feeding is complete, the conveying device 2 is moved, causing the feeding hopper 204 to move to the discharge port 113. Figure 4 As shown, after unscrewing the hand-tightening bolt 110, rotate the baffle 108 upwards to open it. Then, pass the hand-tightening bolt 110 through the baffle 108 and connect it to the internal threaded pipe 111. The raw material in the mixing tank 102 falls into the feeding hopper 204, and is then conveyed by the auger conveyor 203 to the discharge pipe 205. The material then falls into the subsequent processing equipment (such as an extruder) through the discharge pipe 205. After the discharge is completed, move the conveying device 2 back to its original position and reset the baffle 108.
