Description

Technical Field

[0001] This invention belongs to the field of plastic product processing technology, and in particular, it is a heat-printing device for plastic products that is easy to handle. Background Technology

[0002] Thermal printing is an emerging printing technology. This printing process is divided into two main parts: transfer film printing and transfer processing. Transfer film printing uses halftone printing to pre-print the pattern on the surface of a thin film. The printed pattern has rich layers, bright colors, and is ever-changing. It has small color difference, good reproducibility, and can meet the requirements of the designer. It is also suitable for mass production.

[0003] Current heat-printing equipment is often not convenient for automatically clamping different types of plastic products, and positional shifts are prone to occur during heat printing, which reduces the product qualification rate after heat printing.

[0004] For example, the existing Chinese patent number CN216659284U describes a hot stamping device for plastic products, which "includes a base, mounting frame, electric heating controller, lifting cylinder, screw tube, hot stamping mold, top plate, two sets of sliding rods, two sets of limiting blocks, two sets of springs, disc, motor, moving plate, and placement mold. The bottom of the base is provided with four sets of support legs. The bottom of the mounting frame is fixedly connected to the top of the base. The bottom of the electric heating controller is fixedly connected to the top of the mounting frame. The bottom of the lifting cylinder is fixedly connected to the top of the mounting frame. The output end of the lifting cylinder is provided with a cylinder rod that passes through the top of the mounting frame. The top of the screw tube is fixedly connected to the bottom of the cylinder rod. The top of the hot stamping mold is provided with a screw that is threadedly connected to the screw tube. The screw tube is fixedly installed in the top plate. The top plate is provided with two sets of sliding holes. The two sets of sliding rods slide through the two sets of sliding holes respectively. The two sets of limiting blocks are fixedly connected to the tops of the two sets of sliding rods respectively." Although this improves the convenience of material unloading, it is not convenient for automatically clamping different types of plastic products, and positional displacement is prone to occur during hot stamping. Therefore, a new type of heat-printing device for plastic products that is easy to handle is needed. Summary of the Invention

[0040] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0041] This easy-to-use plastic product heat-printing device allows for easy handling. When in use, the plastic product to be heat-printed is placed on a circular platform. The electric lifting column controls the lifting of the platform according to the height of the plastic product. Then, the electric telescopic rod extends to push the clamping plate, holding the plastic product from two directions. When changing to a new model of plastic product, the pin is pulled upwards via the pull ring, disengaging it from the positioning hole. The adjusting platform is then pushed along the sliding groove of the clamping platform to the appropriate position. The pull ring is then released, and under the spring force, the pin inserts into the new positioning hole, completing the clamping mechanism's position adjustment. The combination of the clamping mechanism and its cooperating position adjustment mechanism enhances the versatility of the clamping mechanism.

[0042] This easy-to-use plastic product heat-printing device allows for easy placement and removal of plastic products. Before use, rotating the first turntable drives the moving stage along the optical axis via the second screw to adjust its position. Then, rotating the second turntable drives the T-shaped slider along the inner cavity of the moving stage via the third screw to adjust its position, positioning the heat-pressing plate at a suitable position above the plastic product to be heat-printed. Next, a stepper motor drives the first screw to rotate, which in turn drives the moving heat-printing mechanism to slide vertically downwards along the support column via the drive seat, allowing the heat-pressing plate to heat-print the plastic product. After heat-printing, the lifting mechanism drives the moving heat-printing mechanism back to its original position, and then the clamping mechanism releases its grip on the plastic product, allowing it to be removed. Thanks to the moving heat-printing mechanism, heat-printing can be performed on different positions of the plastic product, improving the convenience of heat-printing. Attached Figure Description

[0062] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0064] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0065] In order to automatically clamp different types of plastic products, such as Figures 1 to 9The illustrated heat-printing device for easy handling of plastic products includes a clamping mechanism 4 and a position adjustment mechanism 5 used in conjunction with it, which improves the versatility of clamping. It includes a base plate 1 and four support columns 2 respectively fixedly installed at the four corners of the base plate 1. The four support columns 2 are together fixedly fitted with a clamping platform 3. The clamping platform 3 is equipped with four sets of clamping mechanisms 4, and the four sets of clamping mechanisms 4 are arranged in a circular array. Each set of clamping mechanisms 4 is fixedly connected to the position adjustment mechanism 5. An electric lifting column 9 is fixedly installed at the center of the base plate 1, and a frustum 8 is fixedly installed on the top of the electric lifting column 9.

[0066] Each clamping mechanism 4 includes:

[0067] Two limiting posts 402 are slidably mounted on the clamping table 3;

[0080] In use, the plastic product to be heat-printed is placed on the circular platform 8. The electric lifting column 9 controls the raising and lowering of the circular platform 8 according to the height of the plastic product. Then, the electric telescopic rod 403 extends and pushes the clamping plate 404 to clamp the plastic product to be heat-printed from two directions. When heat-printing a new model of plastic product, the pin 502 is pulled upward by the pull ring 505, so that the pin 502 is disengaged from the positioning hole. Then, the adjusting table 401 is pushed to the appropriate position along the slide groove of the clamping platform 3. Then, the pull ring 505 is released. Under the action of the spring 504, the pin 502 is inserted into the new positioning hole, and the position adjustment of the clamping mechanism 4 is completed.

[0081] Four support columns 2 are slidably fitted with a movable heat printing mechanism 7. Both ends of the clamping table 3 are equipped with lifting mechanisms 6, and each set of lifting mechanisms 6 is connected to the movable heat printing mechanism 7.

[0099] Before use, rotate the first turntable 706 to drive the moving stage 707 to slide along the optical axis 704 and adjust its position via the second screw 705. Then, rotate the second turntable 709 to drive the T-shaped slider 710 to slide along the inner cavity of the moving stage 707 and adjust its position via the third screw 708, so that the hot press plate 711 is in a suitable position above the plastic product to be heat-printed. Then, the stepper motor 602 drives the first screw 604 to rotate, and the first screw 604 drives the moving heat-printing mechanism 7 to slide vertically downward along the support column 2 via the drive seat 605, so that the hot press plate 711 heat-prints the plastic product. After heat-printing, the lifting mechanism 6 drives the moving heat-printing mechanism 7 to return to its original position, and then the clamping mechanism 4 releases the clamp on the plastic product, so that the plastic product can be removed.

[0100] The electric telescopic pole 403, stepper motor 602, hot press plate 711 and electric lifting column 9 are all existing technologies. Their working principles, dimensions and models are not related to the functions of this application, so they will not be described in detail. They are all controlled by remote control switches.

[0101] Working principle

[0102] Before use, this easy-to-use plastic product heat-printing device places the plastic product to be heat-printed on the circular platform 8. The electric lifting column 9 controls the raising and lowering of the circular platform 8 according to the height of the plastic product. Then, the electric telescopic rod 403 extends to push the clamping plate 404 to clamp the plastic product to be heat-printed from two directions. When changing to heat-print a new model of plastic product, the pull ring 505 pulls the pin 502 upward, causing the pin 502 to disengage from the positioning hole. Then, the adjusting table 401 is pushed to the appropriate position along the slide groove of the clamping table 3. Then, the pull ring 505 is released, and under the action of the spring 504, the pin 502 is inserted into the new positioning hole. The position of the clamping mechanism 4 is adjusted. The first turntable 706 is then rotated. The second screw 705 drives the moving stage 707 to slide and adjust its position along the optical axis 704. Then, the second turntable 709 is rotated to drive the T-shaped slider 710 to slide and adjust its position along the inner cavity of the moving stage 707 via the third screw 708, so that the hot press plate 711 is in a suitable position above the plastic product to be heat-printed. Then, the stepper motor 602 drives the first screw 604 to rotate. The first screw 604 drives the moving heat-printing mechanism 7 to slide vertically downward along the support column 2 via the drive seat 605, so that the hot press plate 711 heat-prints the plastic product. After heat-printing, the lifting mechanism 6 drives the moving heat-printing mechanism 7 to return to its original position. Then, the clamping mechanism 4 releases the clamp on the plastic product, and the plastic product can be removed.
