DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Referring to Figures 1-5 A decorative plate extruder with a cooling mechanism, comprising an extruder main body 1, an extrusion shell 2 is connected to the extrusion end of the extruder main body 1, a layer of spiral water channel 21 is arranged in the extrusion shell 2, a cooling mechanism 3 is arranged at the bottom of the extruder main body 1, the cooling mechanism 3 is connected with the water channel 21, and is used for cooling the extrusion shell 2.

[0025] Among them, the cooling mechanism 3 includes a water tank 31, a water supply pipe 32 connected to both ends of the water channel 21, and a water supply device 33 connected with the pipeline of the water tank 31, and the water supply pipe 32 at both ends is connected with the water tank 31 and the water supply device 33 respectively.

[0026] The water supply device 33 and the water supply pipe 32 are further provided with a filter assembly 4, and the filter assembly 4 is used for filtering cooling water.

[0027] It should be added that the water supply device 33 is a water pump, the water tank 31 is used to store cooling water, the water pump draws cooling water from the water tank 31 through the water supply pipe 32 and delivers it to the water channel 21. After that, the heated cooling water in the water channel 21 returns to the water tank 31 through the water supply pipe 32 at the other end, realizing the recycling of cooling water.

[0028] Furthermore, the filter assembly 4 includes a filter cylinder 41, the two ends of which are connected to the water supply pipe 32 and the output end of the water supply device 33, respectively. A filter channel 42 is also connected to the side of the filter cylinder 41, and a filter screen 44 is detachably connected to the filter channel 42 through a support frame 43.

[0029] Furthermore, the inner wall of the filter cylinder 41 is provided with a first abutment 45 and a second abutment 46 on the upper and lower sides of the connection port of the filter channel 42, respectively, and one end of the support frame 43 is abutted against the first abutment 45 and the second abutment 46 by a sealing ring.

[0030] The filter channel 42 is threaded to an end cap 411, which is provided with a water-stop pad between the end cap 411 and the filter cylinder 41, and the end cap 411 abuts against the other end of the support frame 43.

[0031] It is worth mentioning that the filter cylinder 41 is pressed against the first abutting part 45 and the second abutting part 46 by a sealing ring, and the other end of the filter cylinder 41 is pressed against by the end cap 411 to prevent the filter cylinder 41 from moving in the filter pipe 42.

[0032] Among them, such as Figure 3 As shown, the free end of the second abutment 46 extends downward to form an extension, which abuts against the end of the filter cylinder 41, and the extension, together with the end cap 411, fixes both ends of the filter cylinder 41.

[0033] More specifically, the two ends of the support frame 43 are fitted with the filter channel 42 with a gap, and a number of support bars 431 are arranged in a circular array between the two ends. The filter screen 44 covers the periphery of the support frame 43, and the filter screen 44 is stacked on both ends.

[0034] In general, the filter assembly 4 also includes a fixing plate 47, which is adapted to the length of the support bar 431. The side of the fixing plate 47 is also provided with a number of protruding structures 471 that extend in length. One of the support bars 431 is provided with a through hole 432 corresponding to the protruding structure 471. The protruding structure 471 passes through the beginning and end sides of the filter screen 44 and is provided in the through hole 432.

[0035] It is worth mentioning that the filter screen 44 is preferably made of nylon material, so as to prevent the protruding structure 471 from being inconveniently arranged through the filter screen 44 or causing damage to the filter screen 44 when arranged through the filter screen 44, wherein the protruding structure 471 is in a columnar structure, and a free end thereof is in a conical structure, and the protruding structure 471 is matched with the through hole 432;

[0036] It is worth mentioning that, as shown in Figure 5 The two ends of the support frame 43 are in a ring structure, and there is a certain spacing between the outer edges of the two ends of the support frame 43 and the support bars 431, and the spacing is used to accommodate the fixing plate 47.

[0037] The thickness of the fixing plate 47 is slightly greater than the width of the above-mentioned gap, so that the outer wall of the fixing plate 47 can be tightly abutted with the inner wall of the filter pipeline 42 without being excessively protruded.

[0038] Finally, the fixing plate 47 is arranged in the filter passage 42, and the other side thereof is tightly abutted with the inner wall of the filter passage 42.

[0039] The working mode is that, during working, the water supply device 33 conveys the water in the water tank 31 to the water channel 21 through the water supply pipe 32, and the heated cooling water in the water channel 21 is conveyed to the water tank 31 through the other end of the water supply pipe 32, so as to cool the extruder main body 1 through a recycling mode.

[0040] When the water supply device 33 is pumping water, the cooling water enters the filter cylinder 41 along the water supply pipe 32, and then enters the water channel 21 after being filtered through the filter screen 44.

[0041] When the filter screen 44 needs to be replaced after long-time use, the selected end cover 411 is disassembled, and then the support frame 43 and the filter screen 44 are taken out together, and the fixing plate 47 can be directly taken out after losing the abutting force of the inner wall of the filter pipeline 42, so that the filter screen 44 can be replaced.

[0042] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
