Description

Technical Field

[0001] The invention relates to the technical field of plastic processing, and in particular to a device and method for preparing a PE plastic basket by continuous welding. Background Art

[0002] PE plastic frame generally refers to a frame or container made of polyethylene (PE) material. This material is widely used in various products and industries due to its light, durable, waterproof and corrosion-resistant properties. Traditional PE plastic frame preparation devices have a low degree of automation and require a lot of manual intervention. After the injection molding is completed, there will be strips of plastic residue at the bottom of the plastic frame caused by the injection molding feed, which needs to be removed manually with a spatula. The manual removal of the residue is time-consuming and may affect the overall production efficiency. If the operation is improper, scratches or other surface defects may occur, resulting in inconsistent product quality. Secondly, after the PE plastic frame is injection molded, it is necessary to manually remove the molded plastic frame from the mold and transfer it to the workbench. Manual transfer may cause safety risks such as mold pinching or scalding of high-temperature plastic during injection molding.

[0055] A method used in a continuous welding and forming PE plastic basket preparation device comprises the following steps:

[0056] S1. First, the mixed PE material is fed into the extruder. The material is sheared, extruded and heated by the screw in the barrel of the extruder, gradually melted and plasticized to form a uniform melt. The plasticized melt is extruded through the die head of the extruder body 9 to form a plastic basket blank with a certain shape and size.

[0057] S2, then the plastic frame is taken out from the mold on the extruder body 9 by the cooperation of the clamping and limiting component 8 and the lifting and synchronous flipping component 7 and transported to the fixed frame 305 in the double-station alternating conveying component 3;

[0058] S3, during the alternating conveying process, the double-station alternating conveying component 3 centers and clamps the plastic frame through the synchronous positioning and clamping component 4, and removes the residual waste at the bottom of the plastic frame through the waste removal component 6;

[0059] S4. Finally, the produced plastic frame is taken out from the corresponding fixing frame 305 for subsequent processing.

[0060] Working principle: First, Figure 1 As shown, after the plastic frame is extruded and formed by the extruder body 9 and the mold, the two molds are automatically separated. Fig. 9 , Fig.11 As shown, the No. 1 electric cylinder 712 is controlled to start, and the driving end of the No. 1 electric cylinder 712 extends to push the rack 710 to move. The rack 710 drives the flip rod 708 to rotate clockwise by rotating the gear 711 and the rotating shaft 707. The flip rod 708 drives the lifting frame 705 to rise under the guidance of the two guide rods 704 through the driven rod 709. During the rising process of the lifting frame 705, the fixed shaft 714 cooperates with the flip plate 713 to drive the blanking limit fork 706 to rotate 90° counterclockwise under the guidance of the No. 3 guide groove 716. After the lifting frame 705 has finished rising, the two blanking limit forks 706 are kept horizontally corresponding to the position of the plastic frame on the mold, as shown in FIG. Fig.10 As shown, the second electric cylinder 717 is controlled to be turned on, and the driving end of the second electric cylinder 717 extends to push the moving frame 703 to move under the guidance of the third guide rail 702, so that the two material unloading limit forks 706 move toward the plastic frame, as shown in FIG. Fig.12 As shown, Fig.12The two feeding limit forks 706 are in the clamping state, and the No. 3 electric cylinder 807 is controlled to be turned on. The driving end of the No. 3 electric cylinder 807 contracts and drives the left lever 802 to move toward the side of the lifting frame 705 through the push rod 808. During the movement of the left lever 802, the right lever 802 is driven to move synchronously in the opposite direction through the connecting rod 806 and the rotating plate 805. The two levers 802 approach each other and drive the two feeding limit forks 706 to approach each other synchronously through the disc 803 to clamp and fix the plastic frame. Then the driving end of the No. 2 electric cylinder 717 is controlled to contract and drive the moving frame 703 is reset to separate the plastic frame from the mold, and then the driving end of the No. 1 electric cylinder 712 is controlled to retract, and the lifting frame 705 is driven to reset according to the reverse steps above. During the process of the lifting frame 705 descending and resetting, the plastic frame is driven to flip 90° clockwise so that the bottom of the plastic frame faces downward. The lifting frame 705 is completely lowered. At this time, the plastic frame is located in the fixed frame 305. The driving end of the No. 3 electric cylinder 807 is controlled to extend according to the reverse steps above to drive the two material discharge limit forks 706 to move away from each other and separate from the plastic frame. During the next plastic frame production process of the extruder body 9, as shown in FIG. Figure 6 , Figure 7 As shown, the driving end of the control motor 611 drives the driving shaft 608 to rotate clockwise, and the driving shaft 608 drives the threaded rod 308 to rotate clockwise synchronously through the pulley transmission group. The threaded rod 308 drives the corresponding connecting plate 306 to move to the other end through the slider 309. The two connecting plates 306 move synchronously in opposite directions under the action of the synchronous wheel 310 and the conveyor belt 311. The two fixed frames 305 are on the same horizontal line in a static state. In the alternating process, as shown in FIG. Figure 3 As shown, under the action of the first guide wheel 312 and the first guide groove 313, the two sliding frames 304 move away from each other, so that the two fixed frames 305 are mutually displaced to avoid collision during the alternation process. The two fixed frames 305 continue to move after being displaced. Figure 8 , Fig.13 As shown, the sliding rod 404 continues to move under the action of the No. 2 guide wheel 408 and the No. 2 guide groove 410. During the movement of the sliding rod 404, the two guide plates 401 are driven to approach each other through the swing rod 406. During the movement of the guide plate 401, the four clamping blocks 411 are driven to move centripetally through the transverse groove 402, the inclined groove 407 and the guide column 403 to clamp and fix the plastic frame. During the rotation of the driving shaft 608, the large bevel gear 610 and the small bevel gear 609 drive the driven shaft 604 to rotate. The driven shaft 604 drives the sliding tool holder 602 and the cutting blade 603 to reciprocate under the guidance of the guide rod 601 through the rotating rod 605 and the guide frame 606. The plastic residue at the bottom of the plastic frame is cut off by the reciprocating movement of the cutting blade 603. After the cut plastic frame moves to the end away from the extruder body 9, the plastic frame can be taken out of the fixed frame 305. When the next alternation is required, it is only necessary to control the motor 611 to rotate in the opposite direction.
