Description

Technical Field

[0001] The invention relates to the technical field of extruders, and more specifically to an extruder which is convenient for replacing a filter screen. Background Art

[0002] The extrusion process of plastic is to use the extruder screw to transport, compact, and further melt the plastic to make it in a completely uniform molten state, and then extrude it from the die under pressure, and it is shaped by the forming machinery and cooled to make the required product. Therefore, the extruder is the main equipment for plastic extrusion, which determines the quality and output of the extruded product. The extruder is mainly composed of extruder screw, barrel, heating and cooling system, transmission device and control device, among which the extruder screw is the most important functional component of the extruder, which is responsible for the key functions of the extrusion process such as transportation, compaction, melting, homogenization, pressurization and pumping of the raw materials.

[0003] The equipment we are currently using needs to be used in conjunction with a filter. The filter is used to transport the material to the mold, so that the material can be filtered and the mixing effect of the material can be improved. Since it is not convenient to process and replace the screen inside the equipment, the use effect of the equipment will be affected when it is in use.

[0004] Therefore, it is necessary to provide an extruder that is convenient for replacing the filter screen to solve the above problems.

[0005] new content

[0006] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide an extruder that is easy to replace the filter.

[0007] The technical solution adopted by the present application to solve its technical problems is: an extruder that is easy to replace the filter, including an extrusion tube and a filter assembly, the filter assembly including a mounting block installed on one side of the extrusion tube, the bottom plate of the mounting block is fixedly connected to the bottom block, the top of the bottom block is fixedly connected to the support column, the top of the support column is fixedly connected to the telescopic machine, the input end of the telescopic machine is electrically connected to an external power supply, and a positioning plate is inserted into the interior of the mounting block.

[0008] Furthermore, a fixing plate is fixedly connected to the bottom plate at the output end of the telescopic machine, fixing bolts are installed inside both sides of the fixing plate, and the two fixing bolts pass through the fixing plate and are threadedly connected to the top of the positioning plate respectively.

[0009] Furthermore, a first screen is fixedly connected to the interior of the positioning plate, a second screen is clamped on both sides of the positioning plate, and a handle is fixedly connected to the outer side of the second screen.

[0010] Furthermore, a plurality of fixing bars are fixedly connected to the outer side of the second screen, a plurality of limiting grooves are provided on one side of the positioning plate close to the fixing bars, and a plurality of fixing blocks that match each other are fixedly clamped inside the limiting grooves, and the inside of the limiting grooves matches the fixing bars.

[0011] The beneficial effects of this utility model are:

[0012] The utility model is equipped with a telescopic machine, so that the positioning plate can be quickly taken out from the inside of the mounting block, so that the effect of quick disassembly and installation can be achieved. At the same time, the fixing and disassembly between the fixing bolts and the positioning plate makes it easy to replace the positioning plate as a whole inside the equipment, which is beneficial to the later maintenance and repair of the first screen by the equipment, and the second screen can be installed so that the outer side of the first screen can be filtered for the second time, so that the use length of the first screen can be increased. Finally, the second screen can be easily taken out from the inside of the positioning plate through the fixing strip, so that the second screen can be easily replaced on one side of the first screen.

DETAILED DESCRIPTION

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0021] In the present invention, unless otherwise specified, directions such as "up" and "down" are usually relative to the directions shown in the drawings, or relative to the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "left" and "right" are usually relative to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0022] like Figure 1-4 As shown, the present application provides an extruder that is easy to replace the filter screen, including an extrusion tube 1 and a filter assembly 2, the filter assembly 2 includes a mounting block 201 installed on one side of the extrusion tube 1, the bottom plate of the mounting block 201 is fixedly connected to a bottom block 202, the top of the bottom block 202 is fixedly connected to a support column 203, the top of the support column 203 is fixedly connected to a telescopic machine 204, the input end of the telescopic machine 204 is electrically connected to an external power supply, and a positioning plate 205 is inserted into the interior of the mounting block 201.

[0023] The output end bottom plate of the telescopic machine 204 is fixedly connected with a fixing plate 206 , and fixing bolts 207 are installed inside both sides of the fixing plate 206 . The two fixing bolts 207 pass through the fixing plate 206 and are threadedly connected to the top of the positioning plate 205 .

[0024] The interior of the positioning plate 205 is fixedly connected with a first screen 208 , the two sides of the positioning plate 205 are clamped with second screens 209 , and the outer side of the second screen 209 is fixedly connected with a handle 211 .

[0025] A plurality of fixing bars 210 are fixedly connected to the outer side of the second screen 209 , and a plurality of limiting grooves 213 are formed on one side of the positioning plate 205 close to the fixing bars 210 . The inside of the limiting grooves 213 is adapted to the fixing bars 210 .

[0026] The interiors of the plurality of limiting grooves 213 are fixedly connected with mutually adapted fixing blocks 212 .

[0027] When the equipment needs to replace the first screen 208, the telescopic machine 204 can be opened to move the positioning plate 205 upward inside the mounting block 201 and take it out. At this time, the positioning plate 205 will be on the top of the mounting block 201, and then the surfaces of the two second screens 209 will adhere to the material. The staff holds the handle 211 and rotates it to expose the fixing bar 210 inside the limiting groove 213, and then several fixing blocks 212 are taken out from the limiting groove 213 respectively, so that the second screen 209 can be taken out on one side of the first screen 208, thereby achieving the effect of quick disassembly. At this time, the material on the surface of the second screen 209 can be processed, or the second screen 209 itself can be replaced as a whole;

[0028] After the second screen 209 is replaced, it needs to be reset and installed. At this time, the fixing strip 210 can be aligned with the position of each limiting groove 213, and then the second screen 209 is rotated together with the fixing strip 210, so that the fixing strip 210 can be snapped into the inside of the limiting groove 213, so that the second screen 209 can be preliminarily installed. At the same time, by installing the fixing block 212 in the position of the limiting groove 213, the limiting groove 213 can be blocked, thereby further improving the installation effect of the second screen 209 and avoiding shaking. Finally, by opening the telescopic machine 204, the positioning plate 205 can re-enter the interior of the installation block 201, so that the equipment can work again.
