[0027] This utility model provides, for example Figure 1 The silicone tube extruder shown for easy filter replacement includes an extruder body 1, and also includes:

[0028] The filter mechanism 2, located at the discharge port of the extruder body 1, is used to filter the silicone tube material.

[0029] To facilitate the installation and replacement of filter plate 205, such as Figure 1-5 As shown, the filter mechanism 2 includes a fixed ring 201. Multiple connecting seats 202 are evenly spaced and fixedly installed on the outer walls of both ends of the fixed ring 201. Connecting bolts 203 are provided between the multiple connecting seats 202 at one end and the extruder body 1. A filter plate 205 is movably inserted into the inner side of the fixed ring 201. A pressure plate 207 is rotatably installed on one side of the fixed ring 201. A traction spring 211 is fixedly installed on the inner wall of the top of the pressure plate 207. A fastening plate 212 is fixedly installed at the bottom of the traction spring 211. Fastening bolts 214 are provided between the outer side of the fastening plate 212 and the pressure plate 207. The connecting bolt 203 penetrates the inner wall of one end of the extruder body 1 and is threadedly connected to the inner wall of the adjacent multiple connecting seats 202, so that the filter mechanism 2 can be installed at the discharge end of the extruder body 1. The filter plate 205 can be installed and fixed by the fixing ring 201 and the pressure plate 207. The fastening plate 212 can press the filter plate 205 under the elastic force of the traction spring 211. The fastening bolt 214 penetrates the inner wall of the pressure plate 207 and abuts against the outer wall of the fastening plate 212, so that the filter plate 205 remains stable inside the fixing ring 201 and the pressure plate 207.

[0030] To facilitate the extrusion of silicone tubes, such as Figure 1-2 and Figure 4 As shown, the extruder body 1 includes a support base 101, a fixed outer shell 102 is fixedly installed on the top of the support base 101, a feed hopper 103 is fixedly installed at one end of the top of the fixed outer shell 102, a screw rod 104 is rotatably installed inside the fixed outer shell 102, and a servo motor 105 is fixedly installed on the outer wall of one end of the fixed outer shell 102. The output shaft of the servo motor 105 is connected to one end of the screw rod 104. The support base 101 can support and fix the fixed outer shell 102. Material can be added into the fixed outer shell 102 through the feed hopper 103. The servo motor 105 drives the screw rod 104 to rotate, which can extrude the material by screw extrusion.

[0031] To prevent the filter plate 205 from detaching from the retaining ring 201 and the inner side of the pressure plate 207, such as Figure 2 and Figure 5 As shown, a placement groove 204 is provided at the bottom inner side of the fixing ring 201, and a plug ring 206 is fixedly installed on the outer side of the filter plate 205. The inner wall of the placement groove 204 is movably connected to the outer wall of the plug ring 206. A fixing groove 208 is provided on the inner side of the pressure plate 207. The fixing groove 208 is movably sleeved on the outer side of the top of the plug ring 206. A fixing bolt 209 is threaded into the inner wall of one side of the pressure plate 207. The bottom of the fixing bolt 209 is threaded to the inner wall of the fixing ring 201. The placement groove 204 and the fixing groove 208 can fix the plug ring 206 on the outer side of the filter plate 205. The fixing bolt 209 passes through the pressure plate 207 and is threaded to the inner wall of the fixing ring 201, so that the filter plate 205 remains stable inside the fixing ring 201 and the pressure plate 207.

[0032] In order to ensure that the fastening plate 212 can stably press the filter plate 205, such as Figure 2-3 and Figure 5 As shown, movable grooves 210 are provided on both sides of the notch position of the fixed groove 208. Slider blocks 213 are fixedly installed on both outer walls of the fastening plate 212. The inner walls of the two movable grooves 210 are movably connected to the outer walls of the two sliders 213 respectively. The fastening plate 212 is movably sleeved on the outer side of the top of the insertion ring 206. The pressure plate 207 is threadedly connected to the outer wall of the fastening bolt 214. The bottom of the fastening bolt 214 abuts against the outer wall of the fastening plate 212. The fastening bolt 214 is movably inserted into the traction spring. Inside the spring 211, the fastening plate 212 can be sleeved onto the outer top of the insertion ring 206 under the elastic force of the traction spring 211. The movement of the adjacent slider 213 can be limited by the movable groove 210. The fastening bolt 214 penetrates the inner wall of the pressure plate 207 and abuts against the outer wall of the fastening plate 212, so that the fastening plate 212 can firmly press and limit the filter plate 205, so that the filter plate 205 remains stable inside the fixing ring 201 and the pressure plate 207.

[0033] When installing and using the filter mechanism 2, the filter plate 205 is inserted into the inner wall of the fixing ring 201, so that the insertion ring 206 can be inserted into the placement groove 204. Then, by rotating the pressure plate 207, it can press the top of the filter plate 205, so that the fixing groove 208 can be fitted onto the outer side of the top of the insertion ring 206. Then, the fixing bolt 209 is used to pass through the pressure plate 207 and be threaded to the inner wall of the fixing ring 201, so that the filter plate 205 can remain stable inside the fixing ring 201 and the pressure plate 207. At the same time, when the pressure plate 207 presses the filter plate 205, the fastening plate 212 is squeezed and pushes towards the inner side of the pressure plate 207. The movement of the part causes the traction spring 211 to contract. After the pressure plate 207 is connected to the fixed ring 201, the fastening plate 212 is sleeved on the outside of the insertion ring 206 under the elastic force of the traction spring 211, which can press and limit the filter plate 205. At the same time, the movable groove 210 can limit the movement of the adjacent slider 213, so that the fastening plate 212 remains stable during the movement. Then, the fastening bolt 214 is used to penetrate the inner wall of the pressure plate 207 and abut against the outer wall of the fastening plate 212, so that the fastening plate 212 can stably press the filter plate 205, which can prevent the filter plate 205 from moving or shifting during the operation.

[0034] Then, the filter mechanism 2 is installed at the discharge port of the extruder body 1. The connecting bolt 203 is used to penetrate the inner wall of one end of the fixed housing 102 and is threaded to the inner wall of the adjacent connecting seat 202, so that the filter mechanism 2 can be stably installed at the port of the extruder body 1. Material can be added into the fixed housing 102 through the feed hopper 103. The servo motor 105 drives the screw rod 104 to rotate, which can extrude the material by screw. The material can be filtered through the filter plate 205, which can prevent impurities from entering the subsequent mold. This embodiment specifically solves the problem of low silicone tube extrusion efficiency caused by the inconvenience of installing and replacing damaged filter components in the prior art.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
