[0024] Refer to Figures 1 - 5 .

[0025] In view of the problems mentioned in the above background art, the embodiment of the present utility model provides a novel rubber mixer to solve the above technical problems, and its technical solution is as follows:

[0026] A novel rubber mixer includes: a base, side plate frames 110 fixed on both sides of the base, and two rollers 120 rotatably connected between the two side plate frames 110; the rollers 120 are driven by a driving motor.

[0027] It further includes: a trimming mechanism 130.

[0028] The trimming mechanism 130 includes a fixing plate 131, a rotating shaft 132, a rotating shaft seat 133, a cylinder 134, a U-shaped plate 135, a driving rod 136, a connecting rod 137, an adjusting block 138, and a blade 139.

[0029] Both ends of the connecting rod 137 are rotatably connected between the two side plate frames 110 and are arranged close to the front roller 120.

[0030] The fixing plate 131 is fixed inside the side plate frame 110 and above the front roller 120.

[0031] The rotating shaft 132 is fixed on the fixing plate 131, and the rotating shaft seat 133 is fixed at the tail of the cylinder block of the cylinder 134; the rotating shaft 132 is rotatably connected to the rotating shaft seat 133.

[0032] The U-shaped plate 135 is fixed at the end of the driving part of the cylinder 134. One end of the driving rod 136 is located between the two arms of the U-shaped plate 135 and is rotatably connected to the two arms of the U-shaped plate 135 through a pin shaft; the other end of the driving rod 136 is fixed on the connecting rod 137.

[0033] There are two adjusting blocks 138. The two adjusting blocks 138 are fixed on the connecting rod 137, and the blade 139 is fixed on the adjusting block 138.

[0034] In this embodiment, a through shaft hole is provided on the adjusting block 138, and the adjusting block 138 slides on the connecting rod 137 through the shaft hole; an installation hole 138a communicating with the shaft hole is provided on one side of the adjusting block 138, and a screw is inserted into the installation hole 138a to lock the adjusting block 138 on the connecting rod 137.

[0035] When it is necessary to adjust the position of the blade 139 according to the trimming width, loosen the screw in the installation hole 138a, then slide the position of the adjusting block 138 on the connecting rod 137. After adjusting to the appropriate position, tighten the screw in the installation hole 138a.

[0036] In this embodiment, fixing seats 141 are respectively fixed to the tops of the two side plate frames 110. A guide post 145 is fixedly connected between the two fixing seats 141, and a bidirectional lead screw 142 is rotatably connected between the two fixing seats 141. Among them, two material baffle plates 143 are slidably arranged at intervals on the guide post 145, and the two material baffle plates 143 are respectively threadedly connected to two sections of reverse threads of the bidirectional lead screw 142. A motor 144 is fixed to the outside of the side plate frame 110, and the main shaft of the motor 144 is fixedly connected to one end of the bidirectional lead screw 142.

[0037] By arranging the material baffle plates 143, it is possible to prevent the rubber compound from overflowing between the two rollers 120. By controlling the operation of the motor 144, the position spacing between the two material baffle plates 143 can be adjusted.

[0038] In this embodiment, a receiving tray 150 is arranged on the base between the two side plate frames 110 and below the rollers. The receiving tray 150 is used to collect the scattered rubber compound.

[0039] The working principle of a novel rubber mixer provided by an embodiment of the present utility model is as follows:

[0040] 1. When the mixer needs to perform a sheeting operation after the rubber mixing is completed, according to the cutting position of the burrs on the sheet rubber, the screws in the mounting holes 138a can be loosened first, and then the position of the adjusting block 138 on the connecting rod 137 can be slid and adjusted. After adjusting to the appropriate position, the screws in the mounting holes 138a can be tightened.

[0041] 2. The cylinder 134 works to drive the connecting rod 137 to rotate, adjust the inclination angle of the blade 139, so that the cutting edge of the blade 139 abuts against the sheet rubber. When the sheet rubber comes out from the lower surface of the roller 120 at the front side position, the blade 139 attached to the lower surface of the sheet rubber cuts off the excess edge part, completing the edge cutting operation.

[0042] 3. After the edge cutting operation is completed, control the cylinder 134 to work again to drive the cutting edge of the blade 139 away from the roller 120 to prevent the blade 139 from interfering with the normal operation of the mixer.

[0043] A novel rubber mixer provided by an embodiment of the present utility model has the following beneficial effects: The present utility model designs a novel rubber mixer, and a trimming mechanism is added to the mixer, which can realize the automatic trimming operation of sheet rubber, which is simple, efficient and convenient to operate.
