Description

Technical Field

[0001] The present application relates to the technical field of plastic product processing, and specifically relates to a hot stamping device for plastic product processing. Background Technique

[0002] Plastic product processing, also known as plastic forming processing, is the general term for various processes that convert synthetic resin or plastic into plastic products. It is a relatively large production department in the plastic industry. Plastic processing generally includes plastic batching, forming, machining, joining, finishing, and assembly, etc. The latter four processes are carried out after the plastic has been formed into products or semi-products, and are also known as plastic secondary processing.

[0003] A prior patent (publication number: CN216069212U) discloses a hot stamping device for plastic product production and processing, including a workbench. The upper surface of the workbench is fixedly installed with an installation frame. The upper surface of the installation frame is respectively provided with a controller and a forward and reverse motor. The output end of the forward and reverse motor extends into the interior of the installation frame and is fixedly installed with a vertical lead screw. The surface of the vertical lead screw is threadedly connected with an internally threaded cylinder. The bottom end of the internally threaded cylinder is fixedly installed with a hot stamping block. The lower surface of the hot stamping block is provided with a hot stamping template. A rectangular groove is opened on the upper surface of the workbench. For this hot stamping device for plastic product production and processing, by setting the forward and reverse motor, vertical lead screw, internally threaded cylinder, hot stamping block, heating block and hot stamping template, when hot stamping a plastic plate, the forward and reverse motor is started. The forward and reverse motor drives the vertical lead screw to rotate. The rotation of the vertical lead screw makes the hot stamping template on the hot stamping block hot stamp the plastic plate through the internally threaded cylinder, thereby achieving the purpose of automatic hot stamping and improving work efficiency.

[0004] During the use of the above document, it can achieve automatic ironing, but it lacks the ability of positioning itself, cannot position the workpiece, and at the same time lacks cooling for the workpiece after hot stamping, making it more inconvenient to use. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the present application provides a hot stamping device for plastic product processing, which has the advantages of improving the cleaning effect, etc., and solves the problems raised in the background technique.

[0006] To achieve the above object, the present application provides the following technical solution: A hot stamping device for plastic product processing, including a machine body. There are two push plates on the upper surface of the machine body. Two swing plates are hinged on the side surfaces of the two push plates close to each other. Torsion springs are fixedly connected to the bottom surfaces of multiple swing plates. The other ends of multiple torsion springs are fixedly connected to the push plates close to them. Contact wheels are rotatably connected to the bottom ends of multiple swing plates. A support frame is installed on the upper surface of the machine body.

[0035] See also Figure 1 , Figure 2 and Figure 4 The upper surface of the machine body 1 is provided with a notch 17, and a conveying device 18 is installed on the inner wall of the notch 17.

[0036] A plastic product processing and hot stamping device in the present embodiment, in which the contact wheel 5 is installed in cooperation with the torsion spring 4 and the swing plate 3, can flexibly clamp the workpiece on the body 1 to avoid damage to it, and can also position it so that it can be located at the center of the body 1 to facilitate hot stamping. At the same time, through the cooperation of multiple swing plates 3 and the contact wheel 5, workpieces of different shapes can be clamped, thereby improving the overall practicality.

[0037] The working principle of the above embodiment is as follows: When hot stamping a workpiece, first, the air pump is started, and then the workpiece is placed on the conveying device. At this time, the conveying device 18 conveys the workpiece. When the workpiece moves below the support frame 6, the infrared sensor detects the workpiece. At this time, the two electric valves 16 are opened, enabling the gas to be conveyed to the cylinder 7 through the air source distributor 14 and the connecting pipe 15, causing the cylinder 7 to push the push plate 2 towards the workpiece. The contact wheel 5 contacts the workpiece and clamps it. Through the cooperation of the mounting contact wheel 5 with the torsion spring 4 and the swing plate 3, the workpiece on the machine body 1 can be clamped flexibly, avoiding damage to it, and at the same time, it can be positioned so that it can be located at the center of the machine body 1, facilitating hot stamping. At the same time, through the cooperation of multiple swing plates 3 and contact wheels 5, workpieces of different shapes can be clamped, thereby improving the overall practicality. At this time, the telescopic rod 19 pushes the buffer frame 20 downward, causing the hot stamping piece 23 to contact the workpiece and perform hot stamping work. Through the cooperation of the mounting spring 22 and the buffer member 21, the pressure exerted by the hot stamping piece 23 on the workpiece can be buffered, avoiding rigid contact between the hot stamping piece 23 and the workpiece. When the hot stamping of the workpiece is completed, the electric valve 16 closes. At this time, the two cylinders 7 can drive the two push plates 2 to reset. At this time, the conveying device 18 can convey the workpiece to the right end of the machine body 1. At this time, the gas conveyed by the air source distributor 14 can be ejected from multiple nozzles 9 through the exhaust pipe 8. The external water source can enter the atomizer 11 through the water inlet pipe 10, enabling the atomizer 11 to atomize the water source so that it can be sprayed onto the hot-stamped workpiece in cooperation with the airflow, thereby realizing rapid cooling of the workpiece.
