Description

Technical Field

Its structure usually includes a hopper, a screw, a die head, a transmission system, etc. The transmission system plays a key role in power transmission in the extruder. It generally includes key components such as a motor, a reducer, and a coupling. The motor serves as a power source and provides the original power for the entire extrusion process. The size of its power directly affects the production efficiency of the extruder and the scale of materials that can be processed. The existence of the reducer is to convert the high-speed rotation output by the motor into the low-speed and high-torque rotation required by the screw. Such torque conversion can ensure that the material moves forward stably and evenly under the push of the screw, so that it can be smoothly extruded from the die head. The coupling is responsible for tightly connecting the motor and the screw to ensure smooth power transmission. , reduce the loss and fluctuation in the power transmission process. In addition to these main components, the extruder is also equipped with a control system. This control system is like the "brain" of the extruder. It can accurately regulate the speed of the motor, and then adjust the extrusion speed of the material. At the same time, the control system monitors the key parameters such as pressure and temperature of the material at various stages inside the extruder in real time through sensors installed in different parts, such as pressure sensors, temperature sensors, etc. Once these parameters are abnormal, the control system can respond quickly and automatically adjust the corresponding operating parameters, such as adjusting the screw speed, changing the heating power, etc., to ensure the stability and reliability of the entire extrusion process, thereby ensuring the quality of the extruded products.

The inner surface of the mold 1101 is fixedly connected with a positioning rod 1106, and the surfaces of the mold 1101 and the extrusion cylinder 9 are provided with threaded holes 1107. The surface of the mold 1101 is provided with a stopping groove 1108. The inner wall surface of the threaded hole 1107 is threadedly connected with a bolt 1109. The outer end surface of the bolt 1109 is fixedly connected with a connecting rod 1110. The outer wall surface of the connecting rod 1110 is provided with a sliding groove 1111.

Through the setting of the mounting mechanism 11, when the mold 1101 needs to be installed, the mold 1101 is first moved along the One end surface of the extrusion cylinder 9 slides, and during the sliding process, the positioning holes 1103 on the mold 1101 and the extrusion cylinder 9 are gradually aligned. At this time, the second telescopic spring 1104 fixed on the outer wall of the positioning hole 1103 is in a compressed state, and the elastic force generated by it pushes the stopper 1105, thereby driving the positioning rod 1106 to be inserted into the aligned positioning hole 1103, thereby preliminarily achieving a certain degree of positioning of the mold 1101 and the extrusion cylinder 9. Next, the bolt 1109 is screwed into the corresponding threaded holes 1107 on the mold 1101 and the extrusion cylinder 9. During the process of screwing the bolt 1109 in, the connecting rod 1110 fixed on the outer end of the bolt 1109 rotates accordingly, and the slide groove 1111 on the connecting rod 1110 is aligned with the stop pawl 11 The sliders 1113 on the inner side of 12 cooperate with each other, so that the stopping pawl 1112 can slide along the connecting rod 1110.

[0025] Furthermore, the supporting feet 3 are symmetrically arranged at the four corners of the cabinet 1 with respect to the central axis of the cabinet 1, and shock-absorbing pads 4 are arranged at the bottom of each group of supporting feet 3. Through the arrangement of the shock-absorbing pads 4, the shock-absorbing pads 4 are arranged at the bottom of each group of supporting feet 3, which can effectively buffer the impact force that the cabinet 1 may be subjected to during use. When the equipment starts or stops, momentary vibrations may occur. If there are no shock-absorbing pads 4, these vibrations will be directly transmitted to the cabinet 1 body and the internal equipment. Long-term accumulation may cause fatigue damage to the cabinet 1 structure and a decrease in the accuracy of the internal precision equipment or damage. The presence of the shock-absorbing pads 4 can absorb these vibration energies and reduce the impact on the cabinet 1 and the internal equipment.

[0026] Furthermore, the squeezing and pushing mechanism 7 includes a first motor 701, a rotating shaft 702, a gearbox 703, a connecting block 704, a threaded rod 705, a threaded groove 706, a telescopic hole 707, a first telescopic spring 708, a limiting plate 709, a clamping block 710, a clamping hole 711, a main screw 712 and a blade 713. The upper surface of one end of the workbench 5 is fixedly connected to the first motor 701, the one end surface of the first motor 701 is fixedly connected to the rotating shaft 702, the upper surface of the workbench 5 is provided with a gearbox 703, the outer wall surface of one end of the rotating shaft 702 is connected to the connecting block 704, the one end surface of the rotating shaft 702 is fixedly connected to the threaded rod 705, the inner wall surface of the connecting block 704 is provided with a threaded groove 706, the threaded rod 705 The inner wall surface of the telescopic hole 707 is provided with a telescopic hole 707, the inner end surface of the telescopic hole 707 is fixedly connected to the first telescopic spring 708, one end surface of the first telescopic spring 708 is fixedly connected to the limiting plate 709, one end surface of the limiting plate 709 is fixedly connected to the clamping block 710, the inner side surface of the threaded groove 706 is provided with a clamping hole 711, one end surface of the connecting block 704 is fixedly connected to the main screw 712, the outer wall surface of the main screw 712 is fixedly connected to the blade 713, the main screw 712 drives the blade 713 to transmit inside the sleeve 8, through the setting of the squeezing mechanism 7, when the equipment starts to run, first start the first motor 701, the first motor 701 drives the rotating shaft 702 to rotate, and the threaded rod 705 fixed on the rotating shaft 702 rotates When the screw rod 705 is rotated, the inner wall of the connecting block 704 is provided with a thread groove 706 that matches the threaded rod 705. During the rotation of the threaded rod 705, the interaction between the threads causes the connecting block 704 to move along the axial direction of the rotating shaft 702. During the connection process, the first telescopic spring 708 in the telescopic hole 707 is in a compressed or stretched state. The first telescopic spring 708 exerts a force on the limit plate 709, thereby pushing the clamping block 710 to tightly engage with the clamping hole 711 on the inner surface of the thread groove 706. This ensures that the connection between the threaded rod 705 and the connecting block 704 is more stable and prevents loosening or separation during rotation and movement. The movement of the connecting block 704 drives the main screw fixed at one end thereof The rod 712 moves, and the blades 713 fixed on the outer wall of the main screw 712 are transmitted inside the sleeve 8 along with the main screw 712. When the blades 713 rotate in the sleeve 8, they will produce an extrusion and pushing effect on the material. As the main screw 712 continues to rotate, the material gradually moves forward under the extrusion and pushing of the blades 713, realizing the material conveying and extrusion process. The gearbox 703 can adjust the output speed of the first motor 701, thereby changing the speed of the rotating shaft 702, and then adjusting the rotation speed of the main screw 712 and the blades 713. By adjusting the speed, the extrusion speed and extrusion degree of the material can be controlled to meet different production process requirements. For example, when the material needs to be conveyed quickly, the speed can be increased through the gearbox 703.When a more precise extrusion operation is required on the material, the speed can be reduced to achieve this.

[0027] Furthermore, the guide mechanism 10 includes a feed pipe 1001, a hopper 1002, a fixed plate 1003, a second motor 1004, a transmission shaft 1005, a guide pipe 1006, a guide plate 1007 and a screw rod 1008. The upper surface of the sleeve 8 is fixedly connected to the feed pipe 1001, the upper surface of the feed pipe 1001 is fixedly connected to the hopper 1002, the top surface of the hopper 1002 is fixedly connected to the fixed plate 1003, the upper surface of the fixed plate 1003 is fixedly connected to the second motor 1004, and the motor 1006 is fixedly connected to the feed pipe 1001. The bottom surface of 04 is fixedly connected with a transmission shaft 1005, the outer wall surface of the transmission shaft 1005 is fixedly connected with a guide tube 1006, one end surface of the guide tube 1006 is fixedly connected with a guide plate 1007, and the bottom surface of the transmission shaft 1005 is fixedly connected with a screw rod 1008. Through the setting of the guide mechanism 10, first, the material is poured into the hopper 1002, and the hopper plays the role of temporarily storing the material. Then the second motor 1004 is started, and the second motor 1004 drives the transmission shaft 1005 to start rotating. As the transmission shaft 1005 rotates, the screw rod 1008 fixed at the bottom of the transmission shaft starts to rotate, and the screw rod 1008 can continuously push the material in the hopper 1002 downward, so that the material can stably and evenly enter the feed pipe 1001. At the same time, the guide pipe 1006 fixed on the outer wall of the transmission shaft 1005 also rotates with the transmission shaft. The guide plate 1007 at one end of the guide pipe 1006 can guide and adjust the flow direction of the material. When the material enters the area of the guide pipe after being pushed from the hopper through the screw rod, the guide plate 1007 at one end of the guide pipe 1006 can guide and adjust the flow direction of the material. Plate 1007 can guide the material to a specific direction and flow into the feed pipe 1001, ensuring that the material can enter the feed pipe at a suitable angle and speed. From the feed pipe 1001, the material enters the sleeve 8 for subsequent processing. This guide mechanism can effectively control the feeding speed and feeding direction of the material, so that the material is more uniform and orderly when entering the subsequent processing links such as the squeezing mechanism, thereby ensuring the stability and continuity of the entire production process, reducing the occurrence of problems such as material accumulation and blockage, and improving production efficiency and product quality.

[0028] Furthermore, the second motor 1004 and the transmission shaft 1005 cooperate with each other to form a rotating structure, and two groups of guide plates 1007 are arranged inside the hopper 1002. Through the arrangement of the second motor 1004 and the guide plates 1007, the rotating structure formed by the second motor 1004 and the transmission shaft 1005 makes the power transmission more stable and reliable. The motor can continuously and stably output power, and the transmission shaft can efficiently transmit this rotational power to the guide tube 1006 and the screw rod 1008, ensuring the continuity of the material diversion process. At the same time, due to the arrangement of the two groups of guide plates 1007 inside the hopper 1002, the material can be guided from multiple angles during the material diversion process, making the flow of the material more uniform and smooth. This uniform diversion effect can avoid problems such as accumulation and blockage of materials in the hopper 1002, thereby improving the working efficiency of the entire equipment.

[0029] Furthermore, the stop block 1105 cooperates with the positioning rod 1106 through the second telescopic spring 1104 to form a telescopic structure. The positioning rod 1106 is symmetrically arranged in two groups with the central axis of the mold 1101. Through the setting of the positioning rod 1106, the positioning rod 1106 is symmetrically arranged in two groups with the central axis of the mold 1101, which ensures that the mold 1101 can be accurately positioned from two symmetrical directions during installation. When the mold 1101 is assembled with the extrusion barrel 9, the symmetrical positioning rods 1106 can ensure that the relative position of the mold 1101 and the extrusion barrel 9 is accurate, avoiding the displacement of the installation of the mold 1101 and improving the stability of the equipment operation. Moreover, the telescopic structure makes the installation and disassembly operations of the mold 1101 simpler and faster, saving time for equipment maintenance and replacement of the mold 1101.

[0030] Furthermore, the inner wall size of the stop groove 1108 is consistent with the outer size of the stop pawl 1112, and the inner wall size of the slide groove 1111 is consistent with the outer wall size of the slider 1113. Through the setting of the stop groove 1108 and the slide groove 1111, this precise size matching ensures the firmness of the connection between the bolt 1109 and the mold 1101. During the operation of the equipment, the stop pawl 1112 can be tightly stuck in the stop groove 1108, effectively preventing the bolt 1109 from loosening due to equipment vibration and other reasons, thereby ensuring the stability of the connection between the mold 1101 and the extrusion barrel 9, reducing equipment failures and safety hazards that may be caused by loose connections, and improving the reliability of equipment operation.

[0031] Working principle: First, the material is poured into the hopper 1002, and the hopper plays the role of temporarily storing the material. Then the second motor 1004 is started, and the second motor 1004 drives the transmission shaft 1005 to start rotating. As the transmission shaft 1005 rotates, the screw rod 1008 fixed at the bottom of the transmission shaft starts to rotate. The screw rod 1008 can continuously push the material in the hopper 1002 downward, so that the material can enter the feed pipe 1001 stably and evenly. At the same time, the guide pipe 1006 fixed on the outer wall of the transmission shaft 1005 also rotates with the transmission shaft. The guide plate 1007 at one end of the guide pipe 1006 can guide and adjust the flow direction of the material. When the material enters the feed pipe 1001 after being pushed from the hopper through the screw rod When the material enters the guide pipe area, the guide plate 1007 can guide the material to a specific direction and flow into the feed pipe 1001, ensuring that the material can enter the feed pipe at a suitable angle and speed. From the feed pipe 1001, the material enters the sleeve 8 for subsequent processing. This guide mechanism can effectively control the feeding speed and feeding direction of the material, so that the material is more uniform and orderly when entering the subsequent processing links such as the squeezing and pushing mechanism, thereby ensuring the stability and continuity of the entire production process, reducing the occurrence of problems such as material accumulation and blockage, and improving production efficiency and product quality. Then, the first motor 701 is started, and the first motor 701 drives the rotating shaft 702 to rotate, and the threaded rod 705 fixed on the rotating shaft 702 rotates accordingly. The inner wall of the connecting block 704 is provided with a thread groove 706 that matches the threaded rod 705. During the rotation of the threaded rod 705, the connecting block 704 moves along the axial direction of the rotating shaft 702 through the interaction between the threads. During the connection process, the first telescopic spring 708 in the telescopic hole 707 is in a compressed or stretched state. The first telescopic spring 708 exerts a force on the limit plate 709, thereby pushing the clamping block 710 to tightly engage with the clamping hole 711 on the inner surface of the thread groove 706. This ensures that the connection between the threaded rod 705 and the connecting block 704 is more stable and prevents loosening or separation during rotation and movement. The movement of the connecting block 704 drives the main screw 71 fixed at one end thereof 2 moves, and the blades 713 fixed on the outer wall of the main screw 712 are transmitted inside the sleeve 8 along with the main screw 712. When the blades 713 rotate in the sleeve 8, they will produce an extrusion and pushing effect on the material. As the main screw 712 continues to rotate, the material gradually moves forward under the extrusion and pushing of the blades 713, realizing the material conveying and extrusion process. The gearbox 703 can adjust the output speed of the first motor 701, thereby changing the speed of the rotating shaft 702, and then adjusting the rotation speed of the main screw 712 and the blades 713. By adjusting the speed, the extrusion speed and extrusion degree of the material can be controlled to meet different production process requirements. For example, when it is necessary to convey the material quickly, the speed can be increased by the gearbox 703.When a finer extrusion operation is required for the material, the rotation speed can be reduced to achieve this. When the mold 1101 needs to be installed, the mold 1101 is first slid along one end surface of the extrusion cylinder 9. During the sliding process, the mold 1101 and the positioning holes 1103 on the extrusion cylinder 9 are gradually aligned. At this time, the second telescopic spring 1104 fixed on the outer wall of the positioning hole 1103 is in a compressed state, and the elastic force generated by it pushes the stopper 1105, thereby driving the positioning rod 1106 to be inserted into the aligned positioning hole 1103, so that The mold 1101 and the extrusion cylinder 9 are initially positioned to a certain extent. Then, the bolt 1109 is screwed into the corresponding threaded hole 1107 on the mold 1101 and the extrusion cylinder 9. During the process of screwing the bolt 1109, the connecting rod 1110 fixed on the outer end of the bolt 1109 rotates accordingly, and the slide groove 1111 on the connecting rod 1110 cooperates with the slider 1113 on the inner side of the stop pawl 1112, so that the stop pawl 1112 can slide along the connecting rod 1110. When the bolt 1109 is fully screwed in, the sliding stop pawl 1112 is released. The pawl 1112 is moved to fit into the retaining groove 1108 on the surface of the mold 1101, thereby playing a retaining role and preventing the bolt 1109 from loosening. Finally, the nut 1114 is screwed on one end of the bolt 1109 to further enhance the tightness of the connection. When disassembling the mold 1101, the nut 1114 is first unscrewed, and then the bolt 1109 is rotated in the opposite direction to withdraw it from the threaded hole 1107. During this process, the retaining pawl 1112 slides along the connecting rod 1110 and disengages from the retaining groove 1108. Then, the first The elastic force of the second telescopic spring 1104 pulls the positioning rod 1106 out of the positioning hole 1103. At this time, the mold 1101 can be removed from the extruder barrel 9, enabling rapid mold replacement. By adjusting the mold 1101 with different extrusion holes 1102, the shape and size of the extruded strips can be changed, thereby achieving flexible adjustment of the extrusion amount. The model of the first motor 701 is YE2-132S-4, and the model of the second motor 1004 is Y315S-2. This completes the use of an extruder with adjustable extrusion amount.
