Description

Technical Field

[0001] The utility model relates to the technical field of internal mixers, in particular to an internal mixer for temperature control of polyethylene foam boards. Background Art

[0002] The closed plastic mixer is simply called an internal mixer. The main component of the internal mixer is the mixing chamber, also called the plasticating chamber, with a feeding device at the upper part and a discharging device at the lower part, and there is a top bolt at each of the upper and lower parts; when the upper top bolt and the lower top bolt are closed, a closed plasticating chamber is formed.

[0003] During the processing of polyethylene foam board raw materials, an internal mixer is required. When the existing internal mixer feeds powdery raw materials from the feeding port into the mixing chamber, under the action of backflush, powder particles will fly out of the feeding port, causing the phenomenon of material particle diffusion. Working in an environment filled with powder particles for a long time will seriously affect the health of the operating workers; moreover, the flying powdery rubber raw materials also cause waste of resources.

[0004] Therefore, we propose an internal mixer for temperature control of polyethylene foam boards to solve the existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to propose an internal mixer for temperature control of polyethylene foam boards aiming at the problems existing in the background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An internal mixer for temperature control of polyethylene foam boards, including a bottom plate, a feed pipe, a suction ring and a box body. A support seat is provided on the lower surface of the bottom plate, a mixing chamber is provided on one side of the upper surface of the bottom plate, a material cylinder is provided on the mixing chamber, a feed hopper is provided at the upper end of the material cylinder, a suction ring is provided on the upper surface of the feed hopper, the feed pipe penetrates through the suction ring, and the suction ring is interconnected with the box body through a pipe body. The box body is provided on the other side of the upper surface of the bottom plate.

[0007] Preferably, rotors are symmetrically and rotatably installed inside the mixing chamber, a discharge port is installed at the bottom end of the mixing chamber, a valve control is provided on the discharge port, and temperature control sensors are symmetrically embedded on both sides of the inner wall of the mixing chamber.

[0008] Preferably, a cylinder is provided on the upper surface of the material cylinder, a hammer body is installed at the output end of the cylinder, and the hammer body slides inside the material cylinder.

[0009] Preferably, one end of the feed pipe is inserted into the feed hopper, and a control valve is installed on the feed pipe.

[0011] Preferably, there are four support seats in total, and the positions of the four support seats are distributed in a rectangular array on the lower surface of the bottom plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. During the use of the polyethylene foam board temperature control internal mixer of the present utility model, the raw materials for producing the polyethylene foam board enter the feed hopper through the feed pipe under the action of pump transportation. The material falls into the mixing chamber. During this process, a negative pressure is generated inside the box body. Under the action of the negative pressure, the air above the feed hopper is sucked through the suction ring, so as to suck the material particles that spill out of the feed hopper into the box body for collection.
