[0004] In daily production, when cleaning the extruder, the damping plate needs to be removed. The common method is to use the remaining material in the extruder's chamber to push the damping plate out of the chamber by extrusion. However, in actual operation, the damping plate has been stuck on the machine head or stuck on the chamber. In this case, the operator will use tools such as screwdrivers and water pump pliers to remove the damping plate. Although the damping plate can be removed during actual operation, the disassembly process is time-consuming and laborious, causing irreversible damage to the outer cylindrical surface of the damping plate, resulting in dimensional problems and deformation of the sealing surface, causing the subsequent installation state of the damping plate to be abnormal and leaking, affecting the sealing performance and subsequent use, and causing it to be scrapped in severe cases.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Reference Figure 1 A disassembler for disassembling a damping plate between a chamber and a head of an extruder, the disassembler comprising a clamp 1, a block 2, a connecting bolt 3 and an adjusting bolt 4. The clamp 1 is preferably made of stainless steel. The clamp 1 is the main structure of the disassembler and is made of stainless steel, which has a long service life.

[0027] Reference Figure 2 The damping plate 300 has many shapes and specifications, but the structures are similar. Generally, it includes an outer sealing block 301 and a hole plate 302 fixed together. The outer sealing block 301 is a rotating body with an inner cavity. An annular groove 303 is arranged on the outer wall of the outer sealing block 301. Through holes are distributed on the hole plate 302, which can allow the molten material flowing out of the machine chamber 100 to pass through and flow into the machine head 200 for molding. When the material passes through the hole plate 302, the hole plate 302 can have a certain damping effect on the material, allowing the material to pass smoothly and dispersedly.

[0028] The clamp 1 includes two jaws 11, each of which has an arc-shaped inner wall and the arc-shaped inner walls of the two jaws 11 are distributed on the same cylindrical surface; each of the jaws has an arc-shaped inner wall with an arc of 180°, so after the two jaws 11 of the clamp 1 are spliced ​​together, the inner wall of the clamp 1 is a complete cylindrical surface. The jaw 11 can be an arc-shaped flat plate, and the thickness direction of the arc-shaped flat plate is parallel to the center line of the arc-shaped inner wall. The arc-shaped inner walls of the two jaws 11 can cooperate to clamp the outer wall of the outer sealing block 301. The two jaws 11 are arranged symmetrically on the left and right, that is, they are both semicircular, which can adapt to the damping plate 300 with a set outer diameter size.

[0029] A clamping block 2 is provided on the arc-shaped inner wall of each of the clamping jaws 11 for extending into the annular groove 303 of the outer sealing block 301 to limit the axial displacement of the clamping jaw 11 along the outer sealing block 301; the clamping block 2 and the clamping jaw 11 are preferably integrally formed.

[0030] The two clamping jaws 11 are detachably connected together by the connecting bolts 3 so as to cooperate and clamp the outer wall of the outer sealing block 301; the ends of each clamping jaw 11 are respectively provided with connecting holes; each connecting bolt 3 passes through the two connecting holes 12 at the corresponding positions to fix the two clamping jaws 11 together. The two connecting bolts 3 are parallel to each other. In addition, the connecting bolts 3 are perpendicular to the adjusting bolts 4, and the length direction of the connecting bolts 3 is parallel to one of the chords of the cross section of the cylindrical surface where the arc-shaped inner wall of the clamping jaw 11 is located, so that the two clamping jaws 11 are close to each other to clamp the outer sealing block 301.

[0031] There are multiple adjusting bolts 4, each of the clamping jaws 11 is threadedly connected with an adjusting bolt 4, and each of the adjusting bolts 4 is parallel to the center line of the arc-shaped inner wall of the clamping jaw 11, so that the clamp 1 and the damping plate 300 can be moved by turning the adjusting bolt 4. The center line of the adjusting bolt 4, the center line of the arc-shaped inner wall of the clamping jaw 11, and the center line of the outer sealing block 301 are parallel to each other.

[0032] The block 2 on one clamping jaw 11 can be a continuous arc-shaped strip, and the multiple blocks 2 on one clamping jaw 11 can also be dispersed teeth, as long as they can be inserted into the annular groove 303 of the outer sealing block 301. The block 2 can be plate-shaped and have a thickness, and the plate thickness of each of the blocks 2 is not greater than the groove width of the annular groove 303, so that the block 2 can be inserted into the annular groove 303 of the outer sealing block 301. After the block 2 is inserted into the annular groove 303, the axial displacement of the clamp 1 can be limited, so that the clamp 1, the block 2 and the outer sealing block 301 of the damping plate 300 can move together along the axial direction of the clamp 1. The key point of disassembly of the disassembler of the utility model is to allow the block 2 to be inserted into the annular groove 303 of the outer sealing block 301. Therefore, when the damping plate 300 is installed on the machine head 200 and the machine chamber 100, there should be a gap between the machine head 200 and the machine chamber 100, and the annular groove 303 is located at the gap, so that the annular groove 303 is exposed from both the machine head 200 and the machine chamber 100, so that it is convenient for the clamp to extend into the gap and for the block 2 to extend into the annular groove 303. The annular groove 303 is a process groove to assist disassembly.

[0033] For each of the adjusting bolts 4, it includes an integrally formed bolt head and a bolt rod. If the two clamping jaws 11 form a circular ring-shaped clamp 1, and the clamp 1 is an annular plate, the center line of the bolt rod is parallel to the center line of the clamp 1, that is, parallel to the plate thickness direction of the clamp 1, and the axial length of the bolt rod is greater than the plate thickness of the clamp 1, so that the clamp 1 and the block 2 can be driven to move by turning the adjusting bolt 4, and then the damping plate 300 can be driven to move through the block 2.

[0034] After the damping plate 300 is installed on the head 200 and the bore 100 of the extruder, if the damping plate 300 is adhered to the extruder, and one end of the adjusting bolt is exposed from the damping plate 300 and abuts against the head 200 (or the bore 100), the adjusting bolt 4 is turned, and the clamp 1 and the block 2 will move, and the block 2 will also move with the damping plate 300, so that the damping plate 300 is loosened, and the damping plate 300 is convenient to remove. If a plurality of the adjusting bolts 4 are circumferentially distributed on the clamp 1, the adjusting bolts 4 can be turned circumferentially to gradually loosen the damping plate 300 from the extruder. More preferably, the center lines of all the adjusting bolts 4 are distributed on the same cylindrical surface, so that when the adjusting bolts 4 are turned circumferentially, the force applied to the outer sealing block 301 each time can be roughly consistent and uniform. In addition, if the multiple adjustment bolts 4 on the clamp 1 are arranged symmetrically, when tightening the adjustment bolts 4, two symmetrical adjustment bolts 4 can be tightened in sequence as a pair, so that the outer sealing block 301 is subjected to force and moves symmetrically, and the outer wall of the outer sealing block 301 is not easily damaged.

[0035] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
