Description

Technical Field

[0001] The present invention relates to the technical field of silicone extruders, and particularly to a gear-driven synchronous feeding and automatic temperature-controlled silicone extruder. Background Art

[0002] A silicone extruder is a basic equipment in the silicone industry and plays a very important role in the production process of tubes and strips. Most silicone products are extruded by a silicone extruder, especially silicone tubes, silicone strips, silicone profiled sheets, etc. The silicone products produced by a silicone extruder have high production efficiency, large output, and excellent quality.

[0003] The production process flow of a silicone extruder usually includes the following steps: 1. Rubber mixing: The raw material of the mixed rubber is mixed on a two-roll rubber mixer and pressed into a silicone extrusion material; 2. Extrusion molding: Install a mold on the head of the silicone extruder, then cut the refined silicone material into the same size and length, put the silicone raw material into a long drying tunnel, and vulcanize it at high temperature. The silicone product coming out of the drying tunnel is called a semi-finished product; 3. Subsequent processing: The rest is the subsequent processing such as cutting or bonding according to the length and shape required by the customer.

[0004] When producing silicone products, a silicone extruder needs to accurately control the extrusion speed and extrusion temperature to ensure the quality of silicone products. Traditional silicone extruders usually manually adjust the feeding speed and extrusion temperature, which is not only inefficient but also difficult to ensure the quality stability of products. Therefore, 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. Summary of the Invention

[0005] The present invention provides a gear-driven synchronous feeding and automatic temperature-controlled silicone extruder, which solves the problems raised in the above background art, further improves the production efficiency and product quality of the silicone extruder. Through an accurate temperature control system, it can adjust the extrusion temperature in real time, thereby ensuring the physical properties and dimensional accuracy of silicone products and avoiding product defects caused by temperature fluctuations.

[0006] The solution of the present invention to the above technical problems is as follows: A gear-driven synchronous feeding and automatic temperature-controlled silicone extruder, comprising a frame, a driving motor, a transmission gear set, a feeding mechanism, an extrusion barrel, a screw, a water supply temperature control system, a water inlet control system, and a silicone extruder electric box. The transmission gear set, the water supply temperature control system, the water inlet control system, and the silicone extruder electric box are fixedly connected to the frame. The frame is rotatably connected to the extrusion barrel. The driving motor is fixedly installed on the top of the water inlet control system. One end of the transmission gear set is connected to the driving motor, and the other end is connected to the screw. One end of the screw is provided with a first gear, and the driving end of the feeding mechanism is provided with a second gear. The first gear and the second gear are meshed and connected. The second gear is fixedly connected with a feeding roller. The extrusion barrel is evenly provided with temperature measuring holes, and a cooling medium circulation cavity is arranged inside the screw.

[0007] The water supply temperature control system includes a temperature sensor, a control unit, an execution unit, a water tank, a stainless steel heater, a water pump, and an electric proportional valve. The temperature sensor is used to detect the temperature of each temperature measuring hole. The control unit controls the electric proportional valve at the medium circulation inlet at each place to adjust the flow rate separately according to the feedback signal of the temperature sensor. By controlling the flow rate at each place, the temperature control difference at each place can be adjusted to achieve the automatic control of different temperatures at each place. The stainless steel heater is installed at the water tank, and the water pump is fixedly communicated with the water tank and the electric proportional valve.

[0008] On the basis of the above technical solution, the present invention can be further improved as follows.

[0009] Further, two sections of water flow channels are arranged inside the extrusion barrel, and the two sections of water flow channels are respectively located at the front end and the rear end of the extrusion barrel. The extrusion barrel is communicated with a first water inlet pipe and a water outlet pipe for the corresponding two water flow channels.

[0010] Further, the cooling medium circulation cavity can be penetrated by the water pipe of the water supply temperature control system. The cooling medium flows into the bottom of the inner hole of the screw through the water pipe, and then flows out through the cavity of the screw hole to realize the circulation of the cooling medium inside the screw.

[0011] Further, a scraper is fixedly installed inside the feeding mechanism, and the scraper is attached to the feeding roller, so that the residual silicone raw material on the outer wall of the feeding roller can be scraped off.

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

[0013] Further, the feeding roller is communicated with a second water inlet pipe, the second water inlet pipe is communicated with the water supply temperature control system, and a water temperature control cavity is arranged on the inner wall of the feeding roller. The cooling medium can be circulated through the water temperature control cavity to control the temperature of the feeding roller.

[0014] Further, the water temperature control cavity is provided with a water inlet hole communicating with the second water inlet pipe, and the water temperature control cavity is provided with a water outlet hole communicating with the water supply temperature control system, so that the cooling medium liquid can circulate in the water temperature control cavity.

[0015] Further, when the water supply temperature control system needs to be cooled, the stainless steel heater stops working to cool the medium. When the system needs to be heated, the stainless steel heater works to heat the medium, so as to achieve temperature control.

[0016] Further, the electric proportional valve is provided with a plurality of water outlet holes, and the plurality of water outlet holes are respectively communicated with the extrusion barrel, the screw, the feeding roller and the transmission gear set. The medium enters the barrel, the screw, the feeding roller and the transmission gear set to control the temperature.
