In the existing technology, factors that need to be considered in hot stamping devices include temperature, time, pressure and material selection to ensure clear and durable printing effects. At the same time, attention should also be paid to issues such as safety and reliability.

[0003] At present, most of the hot stamping mechanisms on the market require people to manually deliver the items to be hot stamped into the hot stamping device. Due to the high temperature required for hot stamping, people may be burned by hot air or printing blocks when feeding, or the operator may make an operating error and the hot stamping block may press down when feeding, causing the operator to be injured. Therefore, it is necessary to separate the feeding and stamping of personnel to avoid injuries.

[0004] Therefore, in order to solve the above difficult problem, need to design a kind of hot stamping device for plastic product processing. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 to Figure 4 As shown, this embodiment proposes a hot stamping device for plastic product processing, including a base 1, an upper material tray 2, a lower material tray 3, a left feeding mechanism, a right feeding mechanism and a printing mechanism. The upper material tray 2 is fixedly installed on the base 1 by bolts, and the lower material tray 3 is fixedly installed on the base 1 by bolts. The left feeding mechanism and the right feeding mechanism are located on the base 1 and are fixedly installed on the base 1. The left feeding mechanism has the same structure as the right feeding mechanism. The left feeding mechanism or the right feeding mechanism includes a screw guide rail 4, a guide rail motor 14, a slider 5, a lifting cylinder 6, and a lifting cylinder. The lowering mounting plate, the suction cup cylinder 8, the cylinder mounting plate 9, the screw guide rail 4 is located on the base 1 and is fixedly installed on the base 1 by bolts, the slider 5 is slidingly connected to the screw guide rail 4 through the screw on the screw guide rail 4, the lifting mounting plate 7 is fixedly installed on the slider 5 by bolts, the lifting cylinder 6 is fixedly installed on the lifting mounting plate 7 by bolts, the cylinder mounting plate 9 is fixedly installed on the output end of the lifting cylinder 6 by bolts, the suction cup cylinder 8 is fixedly installed on the cylinder mounting plate 9 by bolts, and the printing mechanism is located on the base 1 and is fixedly connected to the base 1.

[0027] The printing mechanism includes a heating base plate 10, a printing block 11, a support frame 12 and a pressing cylinder 13. The heating base plate 10 is fixedly installed on the base 1 by bolts. The heating base plate 10 is provided with a heating air outlet 17 at the position where the material is placed on the base plate. Two hot air blowers are provided at the bottom of the heating base plate 10. The hot air blowers send heat to the material to be heated through the heating air outlet 17 of the base plate, so as to heat the material to the required temperature. The support frame 12 is fixedly installed on the base 1 by welding, and the pressing cylinder 13 is fixedly installed on the support frame 12 by bolts. The printing block 11 is fixedly connected to the output end of the pressing cylinder 13 by bolts. Generally speaking, different materials require different places to be heated, and the printed patterns are also different. The heating base plate 10 is installed with the base 1 by bolts. When different materials need to be replaced, the heating base plate 10 corresponding to the material can be replaced. At the same time, the printing block 11 can also be replaced with printing blocks 11 of different shapes by bolts.

[0028] Since the feeding mechanism in this embodiment is provided with a left feeding mechanism and a right feeding mechanism, and the two feeding mechanisms need to control the left and right movement of the same material, therefore, in this embodiment, the guide motor 14 is preferably driven by a servo motor. The advantage of the servo motor is that it can accurately control the position. Through the setting, the two servo motors can achieve synchronous rotation. At the same time, the speed of the servo motor is also faster, and the heat and noise are lower, which can increase work efficiency.

[0029] The feeding mechanism can also be set up with four groups at the same time, two groups for feeding and two groups for unloading, which can speed up the work efficiency. The diagram of this embodiment only shows the solution of two groups of feeding mechanisms.

[0030] Different materials have different shapes, and the shapes required for the loading tray 2 and the unloading tray 3 are also different. The loading tray 2 and the unloading tray 3 can also be replaced by bolts. Both the loading tray 2 and the unloading tray 3 are provided with a positioning block 15. Since the moving distance of the servo motor and the heating position of the heating base plate 10 are fixed, the loading tray 2 is provided with a positioning block 15 to prevent the material from being placed incorrectly during manual loading, resulting in the heating base plate 10 heating in the wrong position, resulting in reduced work efficiency. The unloading tray 3 is provided with a positioning block 15 to help manual unloading quickly and avoid the material translation caused by air resistance or low friction when the suction cup cylinder 8 is unloading, resulting in the need to sort out the already hot-stamped materials before manual collection, resulting in reduced work efficiency.

[0031] Both the upper material tray 2 and the lower material tray 3 are provided with a circular groove 16 , so that the bottom of the upper material tray 2 and the lower material tray 3 will not completely fit with the materials, and the operator can quickly put the materials into the upper material tray 2 or take them out from the lower material tray 3 through the circular groove 16 .

[0032] Compared with ordinary mechanical grippers, the suction cup cylinder 8 can save some space and improve work efficiency.

[0033] The lifting cylinder 6 is a rodless cylinder. The use of a rodless cylinder for the lifting cylinder 6 can save space and prevent the feeding mechanism and the printing mechanism from interfering with each other.

[0034] The air outlet of the heating base plate 10 corresponds to the printing block 11, so that the heating can be accurately applied to the position where printing is required, thereby improving work efficiency.

[0035] The specific installation process of this embodiment is as follows: the loading tray 2 is fixedly installed on the base 1 by bolts, the unloading tray 3 is fixedly installed on the base 1 by bolts, the screw guide rail 4 is fixedly installed on the base 1 by bolts, the slider 5 is slidably connected with the screw guide rail 4 through the screw on the screw guide rail 4, the cylinder mounting plate 7 is fixedly installed on the slider 5 by bolts, the lifting cylinder 6 is fixedly installed on the lifting mounting plate 7 by bolts, the cylinder mounting plate 9 is fixedly installed on the output end of the lifting cylinder 6 by bolts, the suction cup cylinder 8 is fixedly installed on the cylinder mounting plate 9 by bolts, the heating bottom plate 10 is fixedly installed on the base 1 by bolts, the heating bottom plate 10 is provided with a heating air outlet 17 at the position where the material is placed on the bottom plate, and two hot air blowers are provided at the bottom of the heating bottom plate 10, and the hot air blowers send heat to the material to be heated through the heating air outlet 17 of the bottom plate, so as to heat the material to the required temperature, the support frame 12 is fixedly installed on the base 1 by welding, and the pressing cylinder 13 is fixedly installed on the base 1 by screws The bolt is fixedly installed on the support frame 12, and the printing block 11 is fixedly connected to the output end of the pressing cylinder 13 by bolts. When working, firstly, the material to be hot stamped is placed on the loading tray 2 manually, and then the start button is pressed to drop the lifting cylinder 6 to the specified position. The suction cup cylinder 8 touches the material and absorbs the material. The lifting cylinder 6 rises to the specified position, and the servo motor rotates to send the material to the heating base plate 10. At the same time, the next material to be heated and hot stamped is manually put in and waits for the mechanism to reset. After the servo motor is in place, the hot air blower is started to heat the material through the heating vents 17 of the heating base plate 10. After the material is heated for a certain period of time and reaches the required temperature for hot stamping, the pressing cylinder 13 descends to control the printing block 11 to press the material, and the pressing cylinder 13 rises. At the same time, the servo motor starts to send the material to the top of the unloading tray 3, and the lifting cylinder 6 drops to the specified height. After the suction cup cylinder 8 releases the suction and puts the material into the unloading tray 3, all mechanisms are reset to their original positions to complete a round of work.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
