Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of glue pressing machine, specifically point to a kind of glue pressing machine for solid silicone rubber production. BACKGROUND
[0002] Solid silicone rubber can be produced into various kinds of silicone rubber products, and a glue pressing machine is needed in this process. The working principle of the glue pressing machine is to press the glue through heating and pressure to achieve sealing and other functions. The glue pressing machine is usually composed of a heating system, a pressure system and a control system. During operation, the silicone rubber raw material to be processed is placed in the feeder of the glue pressing machine, and the pressing speed, temperature, pressure and other parameters are set according to the specific requirements, and then the machine is started to begin the pressing process. After pressing is completed, the pressed silicone rubber raw material is taken out for subsequent processing or use. For example, a glue pressing machine for rubber product production is disclosed in publication No. CN216359695U, which includes a bottom plate, a gantry frame No. 1 glue roller, a center column and an electric heating wire. The bottom plate is fixed on the top of the gantry frame by bolts. A No. 1 glue roller is installed in the gantry frame through bearings. A No. 2 glue roller is installed on the top of the No. 1 glue roller through bearings. A temperature controller is installed on the top of the gantry frame through a mounting seat. A No. 1 speed reducer motor is installed on one end of the bottom plate through a mounting bracket. The utility model can heat the glue roller, improve its glue pressing efficiency, and can also convey the rubber raw material, which is convenient for personnel to take.
[0003] However, when in use, the pressing is not complete by relying on the No. 1 glue roller and the No. 2 glue roller, and the distance between them cannot be adjusted, which leads to the fact that the actual pressing thickness cannot be adjusted during glue pressing, resulting in the fact that the pressed product may not meet the actual production needs, thereby affecting the subsequent use of the rubber product.
