Description

Technical Field

[0001] The invention relates to the technical field of plastic stamping, in particular to a high-speed fully automatic plastic stamping line. Background Art

[0002] High-speed fully automatic plastic stamping line is a highly automated production equipment. It is mainly composed of feeding system, stamping system, transmission system, discharging system and other structures. When in use, the raw materials are automatically fed into the stamping system through the feeding system. The stamping system uses the mold to stamp the raw materials to form the required shape. The transmission system is responsible for transferring the stamped workpiece to the next process or the discharging system. The discharging system removes the finished stamped parts from the stamping machine and performs necessary inspections and packaging.

[0003] For example, the Chinese patent "A Plastic Gasket Stamping Device" with announcement number CN219926231U includes a stamping device body, a mounting base and a hydraulic device, the bottom end of the stamping device body is fixedly connected to the mounting base, the top surface of the stamping device body is fixedly connected to an operating table, and the back of the operating table is fixedly connected to a support rod, a movable push rod is installed on the surface of the operating table, the top of the support rod is fixedly connected to a clip, and the clip is connected to a hydraulic device through screws, the output end of the hydraulic device is connected to a stamping plate, and the left side of the stamping device body is fixedly connected to a raw material collection box.

[0004] Although the above-mentioned prior art can realize plastic stamping, in actual use, on the one hand, the replacement of the fixed mold and the movable mold is not convenient enough. Usually, when replacing the fixed mold assembly and the movable mold assembly, the overall fixed structure needs to be dismantled, thereby increasing the workload of the operator. On the other hand, the clamping and fixing mechanism is not flexible enough to adjust. When stamping plastics of different sizes, different clamping mechanisms need to be used to fix the raw material tube and the winding tube, thereby reducing the adaptability of the clamping mechanism. Therefore, it does not meet the existing needs. In this regard, we propose a high-speed fully automatic plastic stamping line. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention can clamp and fix the fixed mold assembly through the extrusion rod and the positioning rod. When the fixed mold assembly and the movable mold assembly need to be replaced, the old fixed mold assembly and the movable mold assembly are removed, and then the position of the extrusion rod is adjusted according to the size of the fixed mold assembly. At this time, the second hydraulic telescopic device is turned on, and the extrusion rod is driven to move in the second slide groove by the extension or contraction of the telescopic end of the second hydraulic telescopic device until the extrusion rod moves to a suitable position. At this time, the fixed mold assembly is placed between the extrusion rods. When installing a new movable mold assembly, the connecting seat is aligned with the opening of the first clamping seat and pushed into the first clamping seat. At this time, the second threaded hole on the first clamping seat corresponds to the position of the second threaded hole on the connecting seat, and then fixed by the first bolt. When the stamping operation is performed, the positioning is performed by cooperating with the positioning hole and the positioning rod. At the same time, when the movable mold assembly is stamped, the damper will be squeezed to a certain extent, and the squeezing will cause the damper and the support spring to be compressed. The compression deformation of the damper and the support spring buffers the impact to a certain extent, thereby protecting the fixed mold assembly and simplifying the replacement steps of the fixed mold assembly and the movable mold assembly.

[0018] 2. The present invention can make the replacement of the winding drum more convenient by using the screw rod and the second clamping seat. When the plastic stamping on the raw material drum is completed, the raw material drum is pulled to be removed from the first mounting plate, and then the second bolt is rotated to make the second bolt move outward in the first threaded hole through the external thread until the second bolt is disengaged from the first threaded hole. At this time, the winding drum is removed from the second clamping seat. When installing a new raw material drum and winding drum, the distance between the first mounting plate and the second mounting plate is first adjusted according to their lengths. At this time, the servo motor is turned on to make the output shaft of the servo motor drive the screw rod to rotate. The threads on the outside of the rod drive the first mounting plate and the second mounting plate to move in the first sliding grooves on both sides respectively until the first mounting plate and the second mounting plate move to appropriate positions. At this time, the limiting cylinders at both ends of the new raw material barrel are aligned with the openings of the arc groove and inserted into the arc groove, and then the connecting rods at both ends of the winding drum are aligned with the openings of the second clamping seat and placed in the second clamping seat until the second clamping seat corresponds to the position of the first threaded hole on the connecting rod, and then fixed with the second bolt, so that the replacement of the winding drum is more convenient, and at the same time, the adaptability of the first mounting plate and the second mounting plate to raw material barrels and winding drums of different lengths is improved.

[0019] 3. The present invention can perform dust removal on plastic before stamping through the third hydraulic telescopic device and the electrostatic roller. Before stamping the plastic, one end of the plastic is passed through the electrostatic rollers on both sides and fixed on the winding drum, and the upper and lower ends of the plastic are both in contact with the electrostatic roller. When stamping, the electrostatic roller is energized. When the dust particles on the plastic have complementary charges with the electrostatic roller and the electrostatic roller rotates continuously, the dust particles are adsorbed on the surface of the electrostatic roller. After a period of time, the dust on the electrostatic roller is cleaned by the staff and the third hydraulic telescopic device is turned on at the same time. The extension or contraction of the telescopic end of the third hydraulic telescopic device drives the mounting ear plate to move in the vertical direction together with the electrostatic roller. The position of the mounting ear plate and the electrostatic roller is adjusted to keep the plastic in a tensioned state to avoid the slack of the plastic from affecting the stamping, thereby improving the quality of the stamped product.
