Description

Technical Field

[0001] This utility model relates to the field of plastic basin trimming technology, specifically to a trimming mechanism for a plastic basin trimming machine. Background Technology

[0002] Plastic basins are lightweight, durable, available in a variety of colors, inexpensive, and easy to use, making them widely used in daily life. The most common manufacturing process for plastic basins is injection molding. This involves mixing plastic raw materials, heating and melting them in an injection molding machine, and injecting the mixture under high pressure into a plastic basin mold. After cooling and solidification, the molded basin is removed by a robotic arm, becoming a semi-finished product. Because the plastic is injection molded, the mold's venting channels and the temperature drop as the plastic flows through the mold can cause incomplete fusion and edge cracking. This can result in uneven or sharp edges on the top of the finished basin, damaging its appearance. Trimming is generally required for this process.

[0003] There is a lack of edge trimming tools designed for plastic basins in the current technology. The edge trimming work is mostly done manually. First, the worker places the plastic basin on the placement plate, then rotates it manually, then controls the rotating rod to press it down, and then cuts it. The production efficiency is low and the labor intensity is high. Utility Model Content

[0004] To address the shortcomings of existing technologies, a trimming mechanism for a plastic basin edge trimming machine is proposed. This mechanism solves the problems of low production efficiency and high labor intensity in existing technologies, where workers place the plastic basin on a placement plate, manually rotate it, control the rotating rod to press down, and then perform cutting.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A trimming mechanism for a plastic basin edge trimming machine includes a turntable unit. After the turntable unit receives and limits the plastic basin body, it rotates and drives the plastic basin body to rotate synchronously, so that the trimming unit can trim the edge of the plastic basin body.

[0007] Furthermore, the turntable unit includes several support blocks that are equidistant from the rotation axis of the turntable unit. The support blocks support and limit the plastic basin body to enable the rotating unit to drive the plastic basin body to rotate stably.

[0008] Furthermore, the turntable unit also includes a chassis fixed to the output end of the drive motor, and several support blocks are arranged in a circular array on the chassis. When the plastic basin body is fastened to the chassis, the support blocks support the plastic basin body from the inside.

[0009] Furthermore, the distance between the support block and the rotating shaft is adjustable. Adjusting the distance between the support block and the rotating shaft changes the size of the circle containing the support block's distribution trajectory, so as to facilitate the snapping of the plastic basin body or to support it.

[0010] Furthermore, a slider is fixedly connected to the bottom of the support block, the slider is slidably connected to a slide rail, the slide rail is fixed to the surface of the chassis, the slide rail is arranged radially along the chassis, and the slider slides along the slide rail to adjust the distance between the support block and the rotation axis.

[0011] Furthermore, the turntable unit also includes a limiting plate coaxial with the chassis. The limiting plate is parallel to the chassis and spaced apart. The limiting plate has a sliding groove, and a roller is slidably connected in the sliding groove. The roller is rotatably connected to the support block. When the support block slides on the chassis, it drives the limiting plate to rotate through the cooperation of the sliding groove and the roller to achieve the limiting.

[0012] Furthermore, a limiting component is provided between the limiting plate and the chassis. The limiting component presses the plastic basin body fastened to the chassis from the inside and cooperates with the support block to limit the plastic basin body to ensure stable rotation of the plastic basin body.

[0013] Furthermore, the limiting component includes two cylinders symmetrically arranged about the center of the rotation axis. The cylinders are fixed on the chassis, and the telescopic end of the cylinder is provided with a top block. When the cylinder extends, it causes the top block to abut against the inner wall of the plastic basin body to achieve limiting.

[0014] Furthermore, the trimming unit is located around the turntable unit, and the trimming unit includes a mounting base for mounting trimmers. The mounting base drives the trimmers to approach the edge of the plastic basin body fastened to the turntable unit to achieve trimming and edge trimming.

[0015] Furthermore, the trimming unit also includes a lifting rod for adjusting the height of the mounting base. The lifting rod is rotatable, and rotating the lifting rod causes the mounting base and trimmer to avoid the plastic basin body so that the plastic basin body is engaged with the turntable unit.

[0016] Compared with the prior art, the comprehensive effects brought about by this utility model include:

[0017] This application sets up a turntable unit to support and limit the plastic basin body, and then automatically rotates to drive the plastic basin body that is in contact with it to rotate. In conjunction with the trimming unit, the edge of the plastic basin body is trimmed to achieve edge trimming, which improves the degree of automation. Compared with manual operation, the trimming of the plastic basin is more uniform, thereby improving the edge trimming efficiency, reducing the labor intensity of workers, reducing errors, improving the edge trimming quality of the plastic basin body, and reducing the generation of defective products.

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 4 As shown, a trimming mechanism for a plastic basin edge trimming machine includes a turntable unit. After the turntable unit receives and limits the plastic basin body, it rotates and drives the plastic basin body to rotate synchronously, so that the trimming unit can trim the edge of the plastic basin body.

[0026] By setting up a turntable unit to support and limit the plastic basin body, it automatically rotates to drive the plastic basin body that is in contact with it to rotate. In conjunction with the trimming unit, it trims the edge of the plastic basin body to achieve edge trimming, which improves the degree of automation. Compared with manual operation, the trimming of the plastic basin is more uniform, thereby improving the edge trimming efficiency, reducing the labor intensity of workers, reducing errors, improving the edge trimming quality of the plastic basin body, and reducing the generation of defective products.

[0027] In the trimming mechanism of the plastic basin edge trimming machine in this embodiment, the turntable unit includes several support blocks 2 that are equidistant from the rotation axis 1 of the turntable unit. The support blocks 2 support and limit the plastic basin body so as to enable the rotating unit to drive the plastic basin body to rotate stably.

[0028] Specifically, support block 2 is set to limit the plastic basin from the circumference of the plastic basin body to ensure a stable connection between the plastic basin and the turntable unit. This prevents the plastic basin body from being misaligned or detached when the turntable unit rotates, which would affect the uniform trimming and edge trimming of the plastic basin by the trimming unit and improve the trimming quality.

[0029] In the trimming mechanism of the plastic basin edge trimming machine in this embodiment, the turntable unit also includes a base plate 3 fixed to the output end of the drive motor. Several support blocks 2 are arranged in a circular array on the base plate 3. When the plastic basin body is fastened to the base plate 3, the support blocks 2 support the plastic basin body from the inside.

[0030] Specifically, a base 3 is set to support the plastic basin body and support the installation of support blocks 2. The support blocks 2 are arranged in a circular array to provide uniform circumferential support for the plastic basin, ensuring that the plastic basin is subjected to uniform force, thereby improving the fit and fixation effect. The support blocks 2 support the plastic basin from the inside. When the plastic basin is upside down, the support blocks 2 are located inside the plastic basin cavity, avoiding obstruction of the edges and affecting the operation of the trimming unit.

[0031] Preferably, an abutment block is provided on the outer side of the support block 2. The abutment block can be a rubber block to avoid wear on the plastic basin while effectively supporting the plastic basin. In addition, it generates friction with the inner wall of the plastic basin to improve the limiting and fixing effect.

[0032] In the trimming mechanism of the plastic basin edge trimming machine in this embodiment, the distance between the support block 2 and the rotating shaft 1 is adjustable. Adjusting the distance between the support block 2 and the rotating shaft 1 changes the size of the circle where the distribution trajectory of the support block 2 is located, so as to facilitate the snapping of the plastic basin body or support it.

[0033] The distance between the support block 2 and the rotating shaft 1 is adjustable. When the plastic basin is about to be fastened to the outside of the support block 2, the distance between the support block 2 and the rotating shaft 1 is reduced simultaneously to make it easier for the plastic basin to be fastened to the base 3. This avoids the plastic basin not being fastened tightly and affecting the synchronous rotation. After the plastic basin is fastened, the distance between the support block 2 and the rotating shaft 1 is increased simultaneously so that the abutment block on the support block 2 can effectively abut against the inner wall of the plastic basin.

[0034] In the trimming mechanism of the plastic basin edge trimming machine in this embodiment, a slider 4 is fixedly connected to the bottom of the support block 2. The slider 4 is slidably connected to the slide rail 5. The slide rail 5 is fixed to the surface of the chassis 3. The slide rail 5 is arranged radially along the chassis 3. The slider 4 slides along the slide rail 5 to adjust the distance between the support block 2 and the rotating shaft 1.

[0035] Specifically, the support block 2 moves via a pneumatic slide rail structure. A sliding cylinder is installed between the support block 2 and the slider 4. The slider 4 and the support block 2 slide on the slide rail 5 by extending and retracting the sliding cylinder, thereby adjusting the radius of the support block 2. Multiple sliding cylinders extend and retract synchronously, thereby adjusting the circumference diameter by moving multiple support blocks 2 synchronously.

[0036] In the trimming mechanism of the plastic basin edge trimming machine in this embodiment, the turntable unit further includes a limiting plate 6 coaxial with the base plate 3. The limiting plate 6 is parallel to the base plate 3 and spaced apart. A sliding groove 7 is provided on the limiting plate 6. A roller 8 is slidably connected in the sliding groove 7. The roller 8 is rotatably connected to the support block 2. When the support block 2 slides on the base plate 3, the limiting plate 6 is driven to rotate through the sliding groove 7 and the roller 8 to achieve the limiting.

[0037] Specifically, the limiting disk 6 is rotatable, and multiple sliding grooves 7 are provided, the same number as the support blocks 2. The multiple sliding grooves 7 are inclined and have the same inclination angle and length. When the support blocks 2 slide along the slide rail 5, the rollers 8 slide in the sliding grooves 7. The multiple support blocks 2 synchronously drive the rollers 8 to move radially while rolling in the sliding grooves 7, and the limiting disk 6 is driven to rotate. Through the above settings, the limiting disk 6 limits the support blocks 2 through the sliding grooves 7 and the cooperation of the rollers 8, ensuring that the multiple support blocks 2 slide the same distance along the slide rail 5, thereby ensuring that the multiple support blocks 2 are distributed circumferentially to fit against the inner wall of the plastic basin and improving the synchronicity of the movement of the multiple support blocks 2.

[0038] In the trimming mechanism of the plastic basin edge trimming machine in this embodiment, a limiting component is provided between the limiting plate 6 and the base plate 3. The limiting component presses the plastic basin body fastened to the base plate 3 from the inside and cooperates with the support block 2 to limit the plastic basin body to ensure the stable rotation of the plastic basin body.

[0039] The setting of the limit component, in conjunction with the support block 2, further improves the fixing effect on the plastic basin body and enhances the synchronization of the rotation of the plastic basin body and the chassis 3.

[0040] Specifically, the limiting component includes two cylinders 9 arranged symmetrically about the center of the rotation axis 1. The cylinders 9 are fixed on the chassis 3. The telescopic end of the cylinder 9 is provided with a top block 10. The extension of the cylinder 9 causes the top block 10 to abut against the inner wall of the plastic basin body to achieve limiting.

[0041] In the trimming mechanism of the plastic basin edge trimming machine in this embodiment, the trimming unit is located on the periphery of the turntable unit. The trimming unit includes a mounting base 12 for mounting the trimming scissors 11. The mounting base 12 drives the trimming scissors 11 to approach the edge of the plastic basin body fastened to the turntable unit to achieve trimming.

[0042] Specifically, the mounting base 12 is used to install and fix the trimmer 11, so that the angle of the trimmer 11 is fixed and a certain angle is maintained with the edge of the plastic basin to trim and remove the excess material on the edge of the plastic basin. This allows for continuous operation and ensures that the cutting allowance of each plastic basin is equal, thereby improving the quality of the plastic basin.

[0043] In the trimming mechanism of the plastic basin edge trimming machine in this embodiment, the trimming unit further includes a lifting rod 13 for adjusting the height of the mounting base 12. The lifting rod 13 is rotatable. Rotating the lifting rod 13 causes the mounting base 12 and the trimming shears 11 to avoid the plastic basin body so that the plastic basin body is engaged with the turntable unit.

[0044] The lifting rod 13 drives the trimmer 11 downwards to approach the edge of the plastic basin, and then the drive motor drives the chassis 3 and the plastic basin to rotate. The edges of the plastic basin are evenly contacted with the trimmer 11 to achieve edge trimming, thereby effectively cutting the excess material. It is set to a rotatable structure, which can avoid obstruction when the plastic basin is fastened to the outside of the support block 2, thus ensuring that the edge trimming is carried out smoothly.
