Description

Technical Field

[0001] The invention relates to the technical field of silicone extruders, in particular to a silicone extruder with gear transmission, synchronous feeding and automatic temperature control. Background Art

[0002] Silicone extruder is a basic equipment in the silicone industry and plays a very important role in the tube and strip production process. Most silicone products are extruded through silicone extruders, especially silicone tubes, silicone strips, silicone special-shaped sheets, etc. Silicone products produced by silicone extruders have high production efficiency, large output and excellent quality.

[0003] The production process of silicone extruder usually includes the following steps: 1. Rubber mixing: the mixed rubber raw materials are mixed in a double-roll rubber mixer and pressed into silicone extrusion materials; 2. Extrusion molding: the mold is installed on the head of the silicone extruder, and then the refined silicone material is cut into shapes of the same size and length, and the silicone raw materials are placed in a long drying oven for high-temperature vulcanization. The silicone products that come out of the drying oven are called semi-finished products; 3. Subsequent processing: the rest is subsequent processing such as shearing or bonding according to the length and shape required by the customer.

[0004] When a silicone extruder is used to produce silicone products, it is necessary to accurately control the extrusion speed and extrusion temperature to ensure the quality of the silicone products. Traditional silicone extruders usually use manual adjustment of the feeding speed and extrusion temperature, which is not only inefficient but also difficult to ensure the quality stability of the product. For this reason, a silicone extruder that can automatically control the feeding speed and extrusion temperature is proposed, which can further improve the extrusion efficiency and product quality of the silicone extruder.

The control unit controls the electric proportional valves at the medium circulation inlets at various locations to adjust the flow rate through the execution unit according to the feedback signal of the temperature sensor. Controlling the flow rate at various locations can achieve differential temperature control at various locations to achieve automatic control of different temperatures at various locations. The stainless steel heater is installed at the water tank, and the water pump is fixedly connected to the water tank and the electric proportional valve.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the cooling medium circulation cavity can be penetrated by a water pipe of a water supply temperature control system, and the cooling medium flows from the water pipe to the bottom of the internal hole of the screw, and then flows out through the screw hole cavity, thereby realizing the circulation of the cooling medium inside the screw.

[0011] Furthermore, a scraper is fixedly installed in the feeding mechanism, and the scraper is in contact with the feeding roller, so that the residual silica gel material on the outer wall of the feeding roller can be scraped off.

[0012] Furthermore, the feeding roller is rotatably connected to a feeding mechanism, and the feeding mechanism is provided with a feeding port.

[0013] Furthermore, the feeding roller is connected to a water inlet pipe, which is connected to a water supply temperature control system.

[0015] Furthermore, when the water supply temperature control system needs to be cooled, the stainless steel heater stops working to achieve medium cooling. When the system needs to be heated, the stainless steel heater starts working to achieve medium heating, thereby achieving temperature control.

[0016] Furthermore, the electric proportional valve is provided with a plurality of water outlets, which are respectively connected to the extrusion barrel, the screw, the feed roller and the transmission gear set, and the temperature can be controlled when the medium enters the barrel, the screw, the feed roller and the transmission gear set.
