It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] A plate filter mounting structure is provided, wherein the plate filter is used for filtering the extruded material of an extruder, and the plate filter 2 includes a sliding plate 21, a pulling assembly 22, and a filter plate 23; The extruder includes a cavity seat 1, which is provided with a discharge channel 10 and a chute 11; The discharge channel 10 extends axially through the cavity seat 1 and is connected to the inner cavity of the extruder; the chute 11 extends horizontally and extends through the cavity seat 1 in a direction perpendicular to the axial direction; the discharge channel 10 passes through the bottom surface of the chute 11 and is connected to the chute 11. The sliding plate 21 is provided with at least two through holes 211, which penetrate the surface of the sliding plate 21; the two through holes 211 are spaced apart along the length of the sliding plate 21; the sliding plate 21 is inserted into the sliding groove 11; The filter plate 23 is embedded in any of the through holes 211; a plurality of filter holes 231 distributed in the filter plate 23 respectively penetrate the filter plate 23; The pulling component 22 is mounted on the side of the cavity seat 1; the output end of the pulling component 22 is connected to one end of the sliding plate 21; the pulling component 22 pulls the sliding plate 21 along the slide groove 11, so that one of the through holes 211 is aligned with the discharge channel 10, and the other through hole 211 is exposed on the side of the cavity seat 1.

[0021] like Figure 1 and Figure 2As shown, before starting the extruder, the filter plate 23 is first installed in a through hole 211 using fasteners. By pulling the assembly 22, the sliding plate 21 is moved so that the other through hole 211, where the filter plate 23 is not installed, is aligned with the discharge channel 10 of the cavity seat 1. Then, the extruder is started, and the old material remaining in the extruder cavity is cleaned out through the other through hole 211. Subsequently, by pulling the assembly 22, the sliding plate 21 is moved so that the through hole 211 where the filter plate 23 is installed is aligned with the discharge channel 10, and the extruded material is continuously output outward through the filter plate 23. At this time, a cleaned spare filter plate can be installed in the other through hole 211. 23. When the filter plate 23 in use becomes clogged and needs to be replaced, the sliding plate 21 is moved by pulling component 22 to align the spare filter plate 23 with the discharge channel 10, so that the extruder can continue to discharge normally. At the same time, the blockage in the filter plate 23 exposed on the side of the cavity seat 1 is cleaned and cleared for backup. When the replaced filter plate 23 becomes clogged, the filter plate 23 can be replaced again by pulling component 22 to move sliding plate 21 in the same way. By repeating this operation and replacing the filter plate 23, the extruder can be kept running continuously without stopping, which can effectively improve the production efficiency of the extruder.

[0022] Preferably, the sliding plate 21 abuts against the bottom surface of the groove 11; The surface of the filter plate 23 facing the inner cavity of the extruder is flush with the surface of the sliding plate 21 that abuts against the groove 11.

[0023] When the filter plate 23 is moved from the discharge channel 10 and replaced, this arrangement prevents material from being left on the surface of the filter plate 23 facing the extruder cavity, thus avoiding material waste.

[0024] Specifically, the pulling assembly 22 includes a mounting plate 221, a driver 222, and at least two connecting rods 224; One end of each of the two connecting rods 224 is fixed to the side of the cavity seat 1, and the other end of each of the two connecting rods 224 is connected to the side of the mounting plate 221 facing the cavity seat 1; the sliding plate 21 is located between the two connecting rods 224. The driver 222 is mounted on the other side of the mounting plate 221 away from the cavity seat 1; the output end of the driver 222 passes through the surface of the mounting plate 221 and is connected to one end of the sliding plate 21.

[0025] like Figure 1 As shown, the driver 222 mounted on the mounting plate 221 can pull the sliding plate 21 to move along the slide groove 11, so that the sliding plate 21 moves closer to or away from the mounting plate 221, and the corresponding through hole 211 is aligned with the discharge channel 10 of the cavity seat 1.

[0026] Furthermore, the pulling assembly 22 also includes a lead screw 223; The sliding plate 21 is also provided with a threaded hole 213; the threaded hole 213 passes through the surface of the sliding plate 21 facing the mounting plate 221 in a horizontal direction and extends into the sliding plate 21; The two through holes 211 are located on the side of the threaded hole 213 away from the mounting plate 221; The lead screw 223 extends horizontally, one end of the lead screw 223 is connected to the output end of the driver 222, the driver 222 drives the lead screw 223 to rotate, and the other end of the lead screw 223 extends into the threaded hole 213, and the lead screw 223 is screwed to the sliding plate 21 through the threaded hole 213.

[0027] like Figure 1 and Figure 2 As shown, the drive 222 drives the lead screw 223 to rotate, which in turn drives the sliding plate 21 to move along the slide groove 11. This improves the smoothness of the movement of the sliding plate 21 and also improves the accuracy of controlling the displacement of the sliding plate 21.

[0028] Furthermore, the sliding plate 21 is also provided with a clearance hole 212; The clearance hole 212 penetrates the surface of the sliding plate 21.

The clearance hole 212 is used to accommodate the lead screw 223 that extends into the sliding plate 21.

[0029] like Figure 1 and Figure 2 As shown, by using the clearance hole 212 to house the portion of the lead screw 223 that extends into the sliding plate 21, the load on the driver 222 can be reduced, and the service life of the driver 222 can be improved.

[0030] Preferably, the actuator 222 is an electric cylinder or a pneumatic cylinder.

[0031] The drive unit 222 can be selected to use an electric cylinder or a pneumatic cylinder, which not only has good operational stability, but also the required power or air source is a matching setting of the extruder, which can improve the convenience of use and maintenance of the drive unit 222.

[0033] like Figure 3 The extruder of this utility model shown uses a plate filter 2 installed in the cavity seat 1. The sliding plate 21 can be moved by the pulling component 22. The filter plates 23 located in the two through holes 211 can be used alternately, which allows the extruder to run continuously without stopping and improves the production efficiency of the extruder.

[0034] In some embodiments, the pulling assembly 22 further includes a driver 222, which is an electric cylinder and is electrically connected to a power source configured for the extruder.

[0035] In other embodiments, the pulling assembly 22 further includes a driver 222, which is a pneumatic cylinder, and the air inlet of the driver 222 is connected to an air source configured in the extruder.

[0036] In summary, such as Figure 1-3 The embodiment of the present invention shown in the figure has a plate filter mounting structure that can improve the ease of cleaning the clogged filter plate 23 by moving the sliding plate 21 by pulling the component 22 and replacing the clogged filter plate 23 with the filter plate 23 located in another through hole 211.
