Description

Technical Field

[0001] The utility model relates to the technical field of plastic product production, and more specifically, it relates to a hot stamping device for plastic products. Background Technique

[0002] Plastic products refer to various products made of plastic materials. Plastic is an artificial material composed of synthetic high-molecular compounds, which has plasticity and can be formed into various shapes and sizes of products through heating and melting followed by cooling and solidification. Plastic products are ubiquitous in life. They are light, durable, and low-cost, and are widely used in multiple fields such as packaging, household, construction, medical, and electronics. Hot stamping is an important means of surface decoration for plastic parts and is also a commonly used decoration process for household appliances and consumer electronic products. It uses a heated hot stamping head to laminate the metal or pigment layer on the hot stamping die onto the surface of the workpiece to be processed to achieve the purpose of decoration or marking.

[0003] After the existing hot stamping equipment hot stamps plastic products, the plastic products are easily adhered to the hot stamping die and are inconvenient to separate, which affects the blanking. At the same time, due to the low melting point of plastic products, their surfaces will be deformed during hot pressing. Finally, during hot stamping, plastic products are prone to emit pungent smoke, which cannot be adsorbed, polluting the production environment. Content of the Utility Model

A hot stamping die 3 is provided on the mounting bracket 2, and a mounting plate 4 is provided on the mounting bracket 2. Slide sleeves 5 are symmetrically provided on the mounting plate 4. A sliding rod 6 is provided in the slide sleeve 5. A limiting plate 7 is provided at one end of the sliding rod 6, and a limiting ring 8 is provided at the other end. A limiting spring 9 is provided between the limiting ring 8 and the mounting plate 4. A cooling plate 10 is provided on the workbench 1. A plurality of cooling pipes 11 are provided in the cooling plate 10. A connecting pipe 12 is provided between the cooling pipes 11. A cooling tank 13 is provided on one side of the workbench 1. Cooling water 14 is provided in the cooling tank 13. A circulating pump 15 and a cooler 16 are provided on one side of the cooling tank 13. A circulating pipe 17 is provided between the cooling tank 13 and the cooling pipes 11. A gas treatment device is provided on the workbench 1. A limiting pad 26 is provided at the bottom of the limiting ring 8. A mounting screw 27 is provided at the top of the hot stamping die 3. The mounting screw 27 is threadedly connected to the mounting bracket 2. The gas treatment device includes an air extractor 28. One end of the air extractor 28 is communicatively connected to a treatment box 29. One end of the treatment box 29 is communicatively connected to an air extraction hood 30. A negative ion adsorption layer 31 and an activated carbon adsorption layer 32 are provided in the treatment box 29.

[0030] In this embodiment, during the hot stamping operation, a suitable hot stamping die 3 is selected and installed on the mounting bracket 2 through the mounting screw 27. The plastic product is placed on the cooling plate 10. The lifting device drives the mounting bracket 2, the mounting plate 4 and the hot stamping die 3 to move downward. The limiting ring 8 and the limiting pad 26 first come into contact with the plastic product. As the mounting plate 4 continues to move, the limiting spring 9 is compressed. The limiting spring 9 gives a downward elastic force to the limiting ring 8 and the limiting pad 26, so that the limiting ring 8 cooperates with the limiting pad 26 to tightly fix the plastic product. Subsequently, when the hot stamping die 3 contacts the plastic product, the surface of the plastic product is hot stamped. At the same time, the air extractor 28 is started, and the exhaust gas is extracted through the air extraction hood 30. The exhaust gas is purified and adsorbed through the negative ion adsorption layer 31 and the activated carbon adsorption layer 32, and then discharged after treatment. At the same time, the cooler 16 and the circulating pump 15 are started. The cooler 16 cools the cooling water 14 in the cooling tank 13. The water inlet end of the circulating pump 15 is communicatively connected to the cooling tank 13, and the water outlet end is communicatively connected to the circulating pipe 17, so that the cooling water 14 circulates between the cooling tank 13 and the cooling pipes 11, thereby cooling the cooling plate 10, and facilitating the rapid cooling of the hot stamped plastic product to prevent the surface of the plastic product from deforming.

[0031] Please refer to Figure 2 Figure 2 As an embodiment of the lifting device: The lifting device includes a lifting screw 18 symmetrically and rotatably arranged on a workbench 1. A lifting sleeve 19 is threadedly connected to the lifting screw 18. A lifting plate 20 is provided between the lifting sleeves 19. A pulley 21 is provided on each lifting screw 18. A transmission belt 22 is provided between the pulleys 21. A lifting motor 23 is provided on the workbench 1. A first bevel gear 24 is provided on the motor shaft of the lifting motor 23. A second bevel gear 25 is provided on the lifting screw 18.

[0032] More specifically, when adjusting the height of the hot stamping die 3, start the lifting motor 23. The motor shaft of the lifting motor 23 drives the first bevel gear 24 to rotate. The first bevel gear 24 drives the second bevel gear 25 and a lifting screw 18 to rotate. Through the action of the pulleys 21 and the transmission belt 22, the synchronous rotation of the two lifting screws 18 is realized, thereby driving the two lifting sleeves 19 and the lifting plate 20 to move, and further moving the height of the mounting bracket 2 and the hot stamping die 3.

[0033] In summary, when the overall equipment is in use or operation: When performing hot stamping operations, select a suitable hot stamping die 3 and install it on the mounting bracket 2 through the mounting screw 27. Place the plastic product on the cooling plate 10. Drive the mounting bracket 2, the mounting plate 4, and the hot stamping die 3 to move downward through the lifting device. The limit ring 8 and the limit pad 26 first come into contact with the plastic product. As the mounting plate 4 continues to move, the limit spring 9 is compressed. The limit spring 9 gives a downward elastic force to the limit ring 8 and the limit pad 26, thereby enabling the limit ring 8 to cooperate with the limit pad 26 to tightly fix the plastic product. Subsequently, when the hot stamping die 3 comes into contact with the plastic product, hot stamp the surface of the plastic product. At the same time, start the air extractor 28, and extract waste gas through the air extraction hood 30. The waste gas is purified and adsorbed through the negative ion adsorption layer 31 and the activated carbon adsorption layer 32, and then discharged after treatment. At the same time, start the cooler 16 and the circulation pump 15. The cooler 16 cools the cooling water 14 in the cooling tank 13. The water inlet end of the circulation pump 15 is connected to the cooling tank 13, and the water outlet end is connected to the circulation pipe 17, so that the cooling water 14 circulates between the cooling tank 13 and the cooling pipe 11, thereby cooling the cooling plate 10, and further facilitating the rapid cooling of the hot-stamped plastic product to prevent deformation of the surface of the plastic product.

[0034] When adjusting the height of the hot stamping die 3, start the lifting motor 23. The motor shaft of the lifting motor 23 drives the first bevel gear 24 to rotate. The first bevel gear 24 drives the second bevel gear 25 and a lifting screw 18 to rotate. Through the action of the pulleys 21 and the transmission belt 22, the synchronous rotation of the two lifting screws 18 is realized, thereby driving the two lifting sleeves 19 and the lifting plate 20 to move, and further moving the height of the mounting bracket 2 and the hot stamping die 3.

[0035] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
