[0001] The invention relates to the field of plastic cup processing, in particular to a trimming device for plastic cup processing. Background Art

[0002] In the plastic cup processing industry, trimming is an indispensable part of the production process, which is directly related to the appearance quality, performance and customer satisfaction of the final product. Traditional trimming devices for plastic cup processing mostly rely on manual operation or simple mechanical cutting. These methods have many defects and are difficult to meet the high standards of efficiency, precision and consistency required by modern industrial production.

[0016] The support member includes a chassis rotatably mounted on a base through a drive shaft, and a servo motor is arranged at the bottom end of the drive shaft. A circular groove is opened at the inner end of the chassis, and multiple groups of first damping springs are arranged in the circular groove. A movable disk is arranged at the other end of the first damping spring, and the movable disk is slidably installed in the circular groove.

[0017] As a further preferred embodiment of the present technical solution, a plurality of rotating plates are rotatably connected to the top of the chassis, and the plurality of rotating plates are arranged in a circular array with the chassis as the axis, a pressure wheel is arranged at the inner end of the rotating plate, a second damping spring is arranged at the bottom of the outer end of the rotating plate, and the bottom of the second damping spring is fixedly connected to the chassis.

[0019] The outer wall of the driving shaft is fixedly connected with a second gear, one side of the second gear is meshedly connected with a third gear, and the other side of the third gear is meshedly connected with a fourth gear.

[0020] Compared with the prior art, it has the following beneficial effects:

[0021] The positioning rod drives the fifth gear and the gear ring to rotate synchronously, and then drives the trimming knife to trim the cup body. In this process, by accurately controlling the relative speed and pressure between the trimming knife and the cup body, the width and depth of the trimming can be very effectively controlled to ensure the consistency and accuracy of the trimming effect, so that the edge of the cup body is smooth and burr-free; the movement of the guide rod in the thread groove and the inclined groove drives the fixed frame, the sliding rod and the movable rod, so that the trimming knife can gradually cut the edge of the cup body from shallow to deep. This progressive trimming method not only improves the quality of trimming, but also reduces the risk of excessive cutting at one time. The risk of damage to the cup body caused by trimming is reduced; when the guide rod moves into the third circular groove, the limiting push rod contacts the outer wall of the cup body, determining the final distance between the trimming knife and the cup body, ensuring stability and consistency during the trimming process. This automatic adaptation and limiting mechanism simplifies the operation process and improves processing efficiency. After the trimming is completed, the elastic force of the third damping spring drives the fixed frame and the sliding rod to move outward, so that the guide rod returns to the initial position through the inclined groove, preparing for the next trimming operation. This elastic reset mechanism not only simplifies the structure of the equipment, but also improves the efficiency of the processing cycle.

[0022] Through the linkage of the vertical rod, the third bevel gear, the first bevel gear, the second bevel gear, the connecting rod and other components, the synchronous operation between the trimming assembly and the conveying system is realized. This design not only simplifies the production process, but also greatly improves the degree of automation of the production line, reduces manual intervention, and thus improves production efficiency; when the two conveyor belts are transmitting, they can stably and continuously convey the cup body from the vertical cylinder to the installation assembly in sequence. This stable unloading rate ensures that the trimming assembly can continuously and efficiently trim the cup body, avoiding production stagnation or efficiency reduction caused by poor unloading; the close cooperation between the conveying system and the trimming assembly realizes the perfect connection of the cup body trimming process. When the cup body is conveyed to the installation assembly, the trimming assembly immediately starts to trim it without the need for additional waiting or adjustment time, thereby further improving production efficiency.

[0023] The servo motor drives the chassis, cup body and transmission system to achieve stable rotation of the cup body during the trimming process. At the same time, the trimming knife in the trimming assembly rotates in the opposite direction to the cup body. This reverse motion helps to remove burrs and uneven parts more thoroughly, improves the flatness and smoothness of the outer wall of the cup body, and thus improves product quality. The pressure plate and pressure wheel combination driven by the opening and closing motor can automatically clamp and limit the cup body during the trimming process, which avoids the cup body from shifting or shaking during the trimming process and ensures the accuracy and stability of the trimming.

[0043] In the embodiment of the present invention, when the mounting assembly 4 is working, the positioning rod 61 drives the fifth gear 68 to rotate synchronously, and the fifth gear 68 drives the meshing ring gear 63 to rotate when rotating, so that when the ring gear 63 rotates, it drives the trimming knife 69 to rotate synchronously, so that the trimming knife 69 trims the cup body 3 during the rotation process;

[0044] The guide rod 620 is initially located at the connection position of the thread groove 623 and the oblique groove 625. As the guide rod 620 rotates, the guide rod 620 moves from the connection position of the thread groove 623 and the oblique groove 625 to the connection position of the third circular groove 624 and the thread groove 623.

[0055] In the embodiment of the present invention, when the cup body 3 in the vertical cylinder 2 is transported to the movable plate 45 at the inner end of the bottom plate 43, the second rotating rod 411 is driven to rotate synchronously by turning on the opening and closing motor 413, and the second rotating rod 411 drives the two second rotating rods 411 to rotate through the two meshing first gears 412, so that the two second rotating rods 411 drive the semicircular plate 414 and the pressure plate 415 to move inward at the same time. Since the surface of the pressure plate 415 is inclined inwardly, the pressure plate 415 can drive the cup body 3 located on the movable plate 45 to move downward during the inward rotation, and at the same time, the pressure wheel 49 is in the second damping spring The elastic force of the spring 410 cooperates with the rotating plate 48 to drive the pressing wheel 49 to rotate inwardly, so as to clamp and limit the position of the cup body 3, so as to avoid the cup body 3 from deflecting inwardly during the trimming process.
