The two stirring shafts are rotatably installed in the mixer, and the motor is connected to one of the stirring shafts. The two stirring shafts are drivingly connected. By the operation of the motor, the two stirring shafts can rotate simultaneously, and the materials inside the mixer can be mixed and stirred.

[0003] When the existing double-shaft mixer is in use, it stirs statically, with poor stirring effect, low mixing efficiency and low stirring range, which cannot meet the use requirements. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and meet the actual needs, and provide a double-shaft mixer. This design can not only perform double-shaft stirring, but also reciprocally move the stirring shafts, which can expand the stirring range and improve the stirring effect.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows:

[0006] Design a double-shaft mixer, including a mixing tank. A tank cover is installed on the top of the mixing tank. A rectangular hole is opened on the tank cover. A regulating plate is slidably installed in the rectangular hole. Two stirring shafts are rotatably installed on the regulating plate. Spiral stirring blades are installed on the outer sides of the two stirring shafts. The two stirring shafts are drivingly connected. A motor is installed on the top of the regulating plate. The motor is connected to one of the stirring shafts. An eccentric wheel is installed on the outer side of the other stirring shaft. A stress block is installed on the top of the mixing tank. The eccentric wheel abuts against the stress block. A plurality of return springs are installed between the regulating plate and the rectangular hole.

[0007] Preferably, four supporting legs are installed at the bottom of the mixing tank. Rubber pads are installed at the bottoms of the four supporting legs. A controller and a feeding port are arranged on the front of the mixing tank. An outlet is arranged on the right side of the mixing tank.

[0008] Preferably, a driving gear is installed on the output shaft of the motor. A driven gear is sleeved on the outer side of the stirring shaft located on the left side of the regulating plate. The driving gear meshes with the driven gear.

[0009] Preferably, sprockets are installed at the top ends of the two stirring shafts. The same chain meshes with the outer sides of the two sprockets.

[0010] Preferably, rectangular bars are installed on the inner walls of both sides of the rectangular hole. Notches are opened on both sides of the regulating plate. The rectangular bars are slidably connected to the inner walls of the corresponding notches.

[0011] The beneficial effects of the utility model are:

[0012] 1. The motor drives the stirring shaft on the left side of the adjustment plate to rotate through the driving gear and the driven gear, and drives the other stirring shaft to rotate through two sprockets and chains. The two stirring shafts rotate synchronously, and the stirring shaft drives the corresponding spiral stirring blades to rotate, which can perform double stirring on the materials. The spiral stirring blades can lift the materials upward to avoid sedimentation;

[0013] 2. The rotation of the stirring shaft on the right side of the adjustment plate drives the eccentric wheel to rotate. The eccentric wheel resists the force block. Through the cooperation of the reset spring, the adjustment plate can move back and forth in the rectangular hole. The adjustment plate drives the two stirring shafts to move back and forth horizontally. The stirring can be carried out by reciprocating movement, which expands the stirring range and improves the stirring effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Example 1: A double mixer, see Figures 1 to 5, including a mixing tank 1. A tank cover 5 is installed on the top of the mixing tank 1. A rectangular hole 6 is opened on the tank cover 5. An adjusting plate 7 is slidably installed in the rectangular hole 6. Two stirring shafts 3 are rotatably installed on the adjusting plate 7. Spiral stirring blades 4 are installed on the outer sides of the two stirring shafts 3. The two stirring shafts 3 are drivingly connected. A motor 12 is installed on the top of the adjusting plate 7. The motor 12 is connected to one of the stirring shafts 3. An eccentric wheel 9 is installed on the outer side of the other stirring shaft 3. A force-receiving block 8 is installed on the top of the mixing tank 1. The eccentric wheel 9 abuts against the force-receiving block 8. A plurality of return springs 17 are installed between the adjusting plate 7 and the rectangular hole 6.

[0022] In this embodiment, four support legs 2 are installed at the bottom of the mixing tank 1. Rubber pads are installed at the bottoms of the four support legs 2. A controller 18 and a feeding port 19 are arranged on the front surface of the mixing tank 1. An outlet 20 is arranged on the right side of the mixing tank 1.
