Description

Technical Field

[0001] This utility model relates to the field of hot stamping technology for plastic parts, and in particular to a hot stamping device for plastic parts. Background Technology

[0002] Hot stamping is an important method of surface decoration for plastic parts. It involves using a heated hot stamping head to press a layer of metal or pigment from a hot stamping die onto the surface of the workpiece to achieve the purpose of decoration or marking.

[0003] For example, Chinese utility model patent CN212331832U discloses a hot stamping equipment for the production and processing of plastic products. During the use of this hot stamping equipment, when there are many plastic products to be hot stamped, it is quite troublesome for the user to fix and disassemble the plastic products through the cooperation between the groove, slide bar, slide sleeve, vertical block and spring. Since hot stamping of plastic parts is a mass production, the above operations reduce the working efficiency of the hot stamping equipment and cannot meet the needs of mass production in factories. Therefore, this application proposes a hot stamping equipment for plastic parts. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a hot stamping equipment for plastic parts.

[0005] An embodiment of this utility model provides a hot stamping device for plastic parts, comprising:

[0006] support;

[0007] A hot stamping assembly; the bracket is equipped with a conveying mechanism for transporting plastic parts, and both conveying mechanisms transport intermittently; the bracket is equipped with a mounting frame, and the mounting frame is equipped with a movable electric push rod. The output end of the electric push rod is fixed with a printing plate. The mounting frame is equipped with a limiting plate, and the limiting plate has a through groove that is opposite to the two conveying mechanisms and allows the printing plate to pass through. The movement of the electric push rod drives the printing plate to move. In conjunction with the intermittently moving conveying mechanisms, hot stamping can be performed on the plastic parts on the two conveying mechanisms.

[0008] Furthermore, the bracket includes a support frame and a U-shaped plate, the U-shaped plate being fixed to the support frame.

[0009] Furthermore, the conveying mechanism includes two shafts rotatably mounted on a U-shaped plate, with transmission rollers fixed on the shafts and connected to each other via a conveyor belt. Multiple rubber frames are fixed on the conveyor belt at equal intervals, and a stepper motor is fixed on the U-shaped plate. The output end of the stepper motor is connected to one of the shafts.

[0010] Furthermore, two toothed rings are fixed on the transmission roller and distributed in front and behind, and two gear belts are fixed on the conveyor belt and distributed in front and behind, and the gear belts mesh with the toothed rings.

[0011] Furthermore, it also includes a support mechanism, which includes a support block fixed to the U-shaped plate, the support block being located between two gear belts, and the support block slidingly abutting against the conveyor belt.

[0012] Furthermore, an electric slide rail is mounted on the mounting bracket, an electric slider is mounted on the electric slide rail, and an electric push rod is mounted on the electric slider.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model features an electric push rod and a reciprocating printing plate, working in conjunction with intermittent conveyor belts on both sides to hot stamp plastic parts in batches. The two conveyor belts work together, avoiding the waiting time required when only one conveyor belt is working, which would otherwise be spent waiting for the conveyor belt to finish conveying before hot stamping can begin. This greatly improves the efficiency of hot stamping plastic parts. Attached Figure Description

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-4 As shown in the figure, this utility model embodiment proposes a hot stamping device for plastic parts, comprising:

[0022] Support 1, wherein support 1 includes a support frame and a U-shaped plate, the U-shaped plate being fixed on the support frame;

[0023] Hot stamping assembly; a conveyor mechanism for conveying plastic parts is installed on the bracket 1, and both conveyor mechanisms convey intermittently; the conveyor mechanism includes two shafts 16 rotatably mounted on a U-shaped plate, a transmission roller 13 is fixed on the shaft 16, the transmission roller 13 is connected to the conveyor belt 4, a plurality of rubber frames 5 are fixed on the conveyor belt 4 at equal intervals, a stepper motor 3 is fixed on the U-shaped plate, the output end of the stepper motor 3 is connected to one of the shafts 16, the output end of the stepper motor 3 rotates intermittently to drive the shaft 16 and the transmission roller 13 to rotate intermittently, thereby realizing the intermittent movement of the conveyor belt 4 and the rubber frames 5. When stopped, the rubber frames 5 are positioned opposite to the printing plate 9.

[0024] To ensure stable movement of the conveyor belt 4, two toothed rings 15 are fixed on the drive roller 13 and two gear belts 14 are fixed on the conveyor belt 4 and are distributed in the front and back. The gear belts 14 mesh with the toothed rings 15, thus ensuring stable movement of the conveyor belt 4.

[0025] A mounting bracket 2 is installed on the bracket 1. A movable electric push rod 8 is installed on the mounting bracket 2. An electric slide rail 6 is installed on the mounting bracket 2. An electric slider 7 is installed on the electric slide rail 6. The electric push rod 8 is installed on the electric slider 7. The electric slider 7 moves back and forth on the electric slide rail 6, which enables the electric push rod 8 and the printing plate 9 to move back and forth. The position of the back and forth movement is between the two through slots 11, that is, from one through slot 11 to the other through slot 11.

[0026] The output end of the electric push rod 8 is fixed with a printing plate 9. A heating wire is installed inside the printing plate 9 to heat the printing plate 9. When the printing plate 9 passes through the through groove 11 and comes into contact with the plastic part, the plastic part can be hot stamped.

[0027] A limiting plate 10 is installed on the mounting frame 2. The limiting plate 10 has a through groove 11 that is opposite to the two conveying mechanisms and allows the printing plate 9 to pass through. The limiting plate 10 is set to block and limit the plastic parts, so as to prevent the printing plate 9 from moving upward and causing the plastic parts to move upward, which would affect the next hot stamping operation of the printing plate 9.

[0028] The electric push rod 8 moves, driving the printing plate 9 to move. In conjunction with the intermittently moving conveyor mechanism, hot stamping can be performed on plastic parts on both conveyor mechanisms. That is, after the plastic parts on one side are hot stamped, the electric push rod 8 resets and moves the conveyor belt 4 where the plastic parts were located. After the electric push rod 8 resets, it moves to the through groove 11 on the other side. Then, the electric push rod 8 drives the printing plate 9 to move down to hot stamp the plastic parts. The above operation is repeated. The electric push rod 8 and the printing plate 9 move back and forth in conjunction with the intermittently conveying conveyor belts 4 on both sides, which can hot stamp plastic parts in batches. The two conveyor belts 4 work together, which avoids the waiting time required when only one conveyor belt 4 is working, which is when hot stamping can only be performed after the conveyor belt 4 has finished conveying. This can greatly improve the hot stamping efficiency of plastic parts.

[0029] However, at this time, the conveyor belt 4 provides support for the plastic parts, but the stability of the support is insufficient. Therefore, this utility model also includes a support mechanism, which includes a support block 12 fixed on the U-shaped plate. The support block 12 is located between the two gear belts 14, and the support block 12 slides against the conveyor belt 4. A crossbeam is installed on the U-shaped plate, and the support block 12 is fixed on the crossbeam. The support block 12 can support the hot-stamped plastic parts.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
