Description

Technical Field

[0001] The present invention relates to the technical field of material processing, and in particular to a high-sound-absorbing hollow EPP extrusion module. Background Art

[0002] EPP itself is a lightweight foam material with a closed-cell structure. It is made of polypropylene resin particles foamed by steam heating. It has good cushioning, heat resistance, chemical stability and recyclability. High-sound-absorbing hollow EPP combines the characteristics of the hollow structure and the EPP material itself, which can achieve good sound absorption effects. It has excellent acoustic performance and light weight. By designing hollow structures in EPP materials, such as cavities, micropores, honeycomb structures, etc., the absorption capacity of sound waves is enhanced, and it is widely used in automobiles, construction, electronic equipment and industrial noise reduction.

[0003] In the existing patent CN213137743U, an EPP foam plastic extrusion die is disclosed, comprising a work platform, an extrusion barrel is fixedly provided on the top of the work platform, a motor is fixedly installed on one side of the extrusion barrel, and the motor is fixedly connected to an extrusion screw through the output end of the extrusion barrel. The beneficial effects of the utility model are as follows: by rotating the rotating handle, the fixing nut moves on the fixing bolt, and then the fixing bolt is rotated outward to rotate the rotating rod until the fixing bolt no longer engages the second groove, and then the die is pulled outward to separate the second clamping block from the second clamping groove and the first clamping block from the first clamping groove. At this time, the die is disassembled, and then the first clamping block on the new die is clamped into the first clamping groove, and then the fixing bolt is rotated so that the fixing bolt is clamped into the second groove, and then the fixing nut is used to fix the fixing bolt. This design is convenient for the user to replace the die, thereby producing products of different shapes, and the replacement operation is simple, which is convenient for the user to use.

[0004] In the above structure, the extrusion of EPP material can be achieved, but during the extrusion process, a filter screen is generally installed on the head of the device to filter impurities in the material, and the filter screen is regularly disassembled and cleaned. The filter screen removal process is relatively troublesome, and the head needs to be disassembled first, and then the filter screen is removed, and the filter screen is transported to the cleaning station for cleaning. The various steps cannot be effectively connected, which reduces the connectivity of the device disassembly steps, makes it impossible to quickly disassemble the head of the device, and makes it difficult to quickly clean the filter screen, which reduces the efficiency of disassembly of the filter screen and thus reduces the extrusion efficiency of the EPP material.

[0031] Working principle: according to the extrusion requirement, the appropriate model of the extrusion mandrel 504 and the extrusion strip 503 are taken, the threaded pipe 501 is butted with the end of the mounting block two 403, the nut 502 is rotated, the threaded pipe 501 is rotatably mounted on the mounting block two 403, the raw material is fed into the feeding hopper 2, the feeding motor 301 is started, the output shaft of the feeding motor 301 is rotated to drive the feeding rod 302 to rotate, the feeding rod 302 is rotated to drive the helical blade 303 to rotate, the helical blade 303 continuously conveys the EPP material, the material is guided into the threaded pipe 501 through the mounting block one 401, the filter screen body 1004 and the mounting block two 403, the material is extruded into the required shape by the action of the extrusion mandrel 504 and the extrusion strip 503, the EPP material is extruded to the next process, and the filtering effect of the EPP material is realized when the material passes through the filter screen body 1004; When the filter body 1004 needs to be disassembled and cleaned, the hydraulic lifting rod is started, and the output end of the hydraulic lifting rod 1101 drives the connecting plate 1102 to move downward, so that the connecting plate 1102 drives the support rod 1103 to move downward, and the support rod 1103 drives the limiting plate 1104 to move downward to a reasonable position, so that the installation groove 1105 moves downward along the filter body 1004 until the limiting plate 1104 blocks the installation block 1 401 and the installation block 2 403, thereby limiting the flow of the material; Start the electric push rod 602, the output end of the electric push rod 602 drives the push block 603 to move, and the movement of the push block 603 drives the toggle rod 704 to move. Under the action of the toggle slot 703, the toggle rod 704 drives the connecting rod 702 to rotate around the shaft 701, so that the connecting rod 702 and the shaft 701 rotate synchronously first, the shaft 701 drives the active bevel gear 805 to rotate, the active bevel gear 805 rotates and drives the driven bevel gear 806 to rotate, the driven bevel gear 806 rotates and drives the transmission rod 802 to rotate, and the transmission rod 802 rotates and drives the pulley 803 to rotate. , through the action of the pulley 803 and the belt 804, the rotating rod 902 is forced to rotate, the rotating rod 902 drives the connecting gear 903 to rotate, the connecting gear 903 rotates and drives the rotating gear 1005 to rotate, the rotating gear 1005 rotates and drives the threaded sleeve 1002 to rotate, the threaded sleeve 1002 drives the threaded rod 1003 to move upward along a straight line, so that the threaded rod 1003 drives the filter body 1004 to move upward, so that the filter body 1004 moves to the maximum height position, at this time the toggle rod 704 moves to the maximum limit in the toggle slot 703; The output end of the electric push rod 602 continues to drive the push block 603 to move. Since the toggle rod 704 moves to the maximum, the push block 603 will force the connecting rod 702 to move linearly. The connecting rod 702 drives the shaft rod 701 to move linearly, so that the shaft rod 701 drives the mounting block 2 403 to move linearly, so that the mounting block 2 403 moves away from the mounting block 1 401.

At the same time, when cleaning, the filter body 1004 is cleaned with a cleaning system without removing the filter body 1004, which is convenient for the staff to operate. After the disassembly and cleaning is completed, the electric push rod 602 retreats, so that the output end of the electric push rod 602 drives the pushing block 603 to retreat. Since the mounting spring 404 is stretched, the mounting spring 404 needs to return to its original state, so that the mounting block 2 403 retreats along the mounting rod 402 close to the mounting block 1 401, so that the mounting block 2 403 and the electric push rod 602 retreat synchronously, and the mounting block 2 403 forces the toggle assembly 7, the transmission assembly 8 and the connecting assembly 9 to retreat synchronously until the mounting block 1 401 and the mounting block 2 403 are connected to form a whole, so that the connecting gear 903 is meshed with the rotating gear 1005, and the electric push rod 602 continues to retreat, and the pushing block 603 drives the toggle rod 704 to toggle the connecting rod 702, so that the connecting rod 702 rotates in the opposite direction around the shaft 701, so that the shaft 701 drives the active bevel gear 805 to rotate, and the active bevel gear 805 rotates to drive the driven bevel gear 806 to rotate, and the driven bevel gear 806 rotates to drive the transmission rod 802 The transmission rod 802 rotates, driving the pulley 803 to rotate.
