DETAILED DESCRIPTION

[0015] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-6 As shown, a hot stamping device for a cosmetic box of the present invention comprises a chain conveyor 1, a machine table 11 is installed at the rear side of the chain conveyor 1, the machine table 11 is installed with a hot stamping mechanism, the chain conveyor 1 is connected to a plurality of U-shaped tables 2, a bearing plate 21 is slidably provided in the U-shaped table 2, a first spring 22 is provided between the bearing plate 21 and the U-shaped table 2, sleeves 23 are rotatably installed on both the front and rear sides of the U-shaped table 2, and a clamping assembly is provided between the two sleeves 23; A slide bar 24 is slidably arranged in the rear sleeve 23, a spiral groove 25 is provided on the inner wall of the rear sleeve 23, a guide block 26 matching the spiral groove 25 is fixed to the slide bar 24, a top block 27 is connected to the rear end of the slide bar 24, a second spring 28 is arranged between the top block 27 and the U-shaped table 2, an electric telescopic rod 12 is installed on the upper side of the machine table 11, and a push block 13 matching the top block 27 is fixed to the output shaft of the electric telescopic rod 12; The clamping assembly includes two sleeves 23 with cross bars 3 fixed on opposite sides, and cross grooves 31 are opened on both sides of the two cross bars 3. Clamps 32 are slidably provided in the two cross grooves 31 on the same side, and a third spring 33 is provided between the clamps 32 and the side walls of the cross grooves 31. A slider 34 is slidably provided in the front sleeve 23, and the slider 34 is connected to the clamp 32 by a pull wire 35. A circular plate 36 is connected to the front side of the slider 34, and a convex strip 37 matching the circular plate 36 is fixed to the middle part of the upper end of the chain conveyor 1, and the two ends of the convex strip 37 are processed with inclined surfaces.

[0017] When the U-shaped platform 2 is on both sides of the chain conveyor 1, the circular plate 36 is not in contact with the convex strip 37, and under the elastic force of the third spring 33, the two clamping plates 32 are away from each other; When in use, the cosmetic box 0 is conveyed to the carrying plate 21, and the chain conveyor 1 can drive the U-shaped table 2 to be conveyed from left to right. After the circular plate 36 contacts the inclined surface of the convex strip 37, the circular plate 36 can be pushed to move forward, thereby driving the slider 34 to slide in the front sleeve 23, and the two clamping plates 32 are pulled by the pull wire 35 to move relative to each other to clamp the cosmetic box 0 in the center. After the cosmetic box 0 moves to the lower side of the hot stamping mechanism, the chain conveyor 1 stops conveying, and the upper surface of the cosmetic box is hot stamped by the hot stamping mechanism. At this time, the top block 27 on the rear side of the U-shaped table 2 is aligned with the push block 13 of the electric telescopic rod 12. After the hot stamping of the upper surface of the cosmetic box 0 is completed, the machine 11 can be started The electric telescopic rod 12 on the side drives the push block 13 to move forward, so that the push block 13 contacts the top block 27, and the top block 27 moves forward, then the slide bar 24 moves forward in the rear sleeve 23, and the guide block 26 fixed by the slide bar 24 slides in the spiral groove 25, which can drive the sleeve 23 to rotate, and the makeup box 0 clamped by the two clamping plates 32 rotates accordingly. When the makeup box 0 rotates, it can push the supporting plate 21 to overcome the elastic force of the first spring 22 and move downward, so as to avoid the supporting plate 21 blocking the makeup box 0. Finally, the makeup box 0 will turn 180°, and its lower surface will face the upper side, and then the lower surface can be stamped by the stamping mechanism to achieve the function of double-sided stamping. After the gilded cosmetic box 0 is conveyed to the rear side of the chain conveyor 1, the two clamping plates 32 move away from each other and do not clamp the cosmetic box 0, so that unloading is convenient; When the cosmetic box 0 is turned over, the front sleeve 23 will also rotate accordingly. The arrangement of the circular plate 36 can ensure that it is always in contact with the convex strip 37 , so that the two clamping plates 32 can stably clamp the cosmetic box 0 .

[0018] A telescopic rod 271 is provided between the top block 27 and the U-shaped platform 2; the telescopic rod 271 can limit the top block 27 so that it can only slide forward and backward to avoid self-rotation.

[0019] The hot stamping mechanism includes a mounting frame 4 mounted on the machine 11, a cylinder 41 is mounted in the middle of the mounting frame 4, an output shaft of the cylinder 41 is connected to an electric heating plate 42, a hot stamping template 43 is arranged at the lower side of the electric heating plate 42, and a hot stamping paper 44 is arranged at the lower side of the hot stamping template 43; A discharging roller 45 is provided on the left side of the mounting frame 4, and a winding roller 46 is provided on the right side of the mounting frame 4, and the hot stamping paper 44 is wound around the discharging roller 45; When the cosmetic box 0 is hot stamped, the electric heating plate 42 heats the hot stamping template 43, and the hot stamping template 43 is driven downward by the cylinder 41 to attach the hot stamping paper 44 to the surface of the cosmetic box 0, and a designated pattern is hot stamped by the hot stamping template 43.

[0020] The output shaft of the cylinder 41 is connected to two vertical slide rails 5, and a sliding block 51 is slidably arranged in each of the two vertical slide rails 5. A mounting plate 52 is fixed between the two sliding blocks 51. The mounting plate 52 is provided with two mounting grooves 53 distributed front and back. The two mounting grooves 53 are both installed with a hot stamping template 43. A fourth spring 54 is arranged between the front side of the sliding block 51 and the vertical slide rail 5, and a push rod 55 is connected to the rear side of the sliding block 51. The output shaft of the electric telescopic rod 12 is detachably connected with an abutment plate 56 that matches the position of the push rod 55 .

[0021] In the initial state, under the elastic force of the fourth spring 54, the mounting groove 53 on the front side of the mounting plate 52 is located below the electric heating plate 42, so that the hot stamping template 43 in the front side mounting groove 53 contacts the electric heating plate 42, and the abutment plate 56 is located at the rear side of the top rod 55. When the top rod 55 moves downward, it will not contact the abutment plate 56. Therefore, when hot stamping is performed on the upper surface of the cosmetic box 0, the pattern on the surface of the hot stamping template 43 can be hot stamped on the upper surface of the cosmetic box 0; When the lower surface of the cosmetic box 0 is stamped, the push block 13 is driven forward by the electric telescopic rod 12, and the slide 24 is pushed forward by the top block 27 to slide forward, so that the cosmetic box 0 is turned 180 degrees, and the electric telescopic rod 12 will simultaneously drive the abutment plate 56 to move forward, so that the abutment plate 56 is located below the top rod 55. Therefore, when the lower surface of the cosmetic box 0 is stamped, the cylinder 41 drives the vertical slide rail 5 to move downward, and the top rod 55 will contact the abutment plate 56, pushing the top rod 55 to move forward, so that the mounting plate 52 slides forward, and the stamping template 43 in the rear mounting groove 53 will move to the bottom of the electric heating plate 42, so that the pattern on the surface of the stamping template 43 can be stamped on the lower surface of the cosmetic box 0, so that different patterns can be stamped on different surfaces of the cosmetic box 0; The abutment plate 56 is detachably fixed on the output shaft of the electric telescopic rod 12 , and the abutment plate 56 can be installed and removed according to actual production needs.

[0022] A movable frame 6 is slidably disposed on the upper side of the machine table 11, the electric telescopic rod 12 and the mounting frame 4 are both mounted on the movable frame 6, a fifth spring 61 is disposed between the right side of the movable frame 6 and the machine table 11, and a groove 272 matching the push block 13 is provided on the top block 27; Since the top block 27 is provided with a groove 272 matching the push block 13, when the push block 13 moves forward, it will first enter the groove 272, and then push the top block 27 forward to turn the cosmetic box 0 over; In this way, the chain conveyor 1 conveys the cosmetic box 0 on the U-shaped table 2 to the bottom of the hot stamping mechanism and then stops conveying. After the hot stamping mechanism completes the hot stamping of the upper surface of the cosmetic box 0, the electric telescopic rod 12 is started to drive the push block 13 to move forward, enter the groove 272 and push the top block 27 to move forward to make the cosmetic box 0 flip 180°. At this time, the chain conveyor 1 can be directly started to work, and the U-shaped table 2 continues to move to the right. Since the push block 13 and the top block 27 are connected to each other, the movable frame 6 will move synchronously with the U-shaped table 2, and the hot stamping mechanism remains stationary relative to the cosmetic box 0. During this process, the cylinder 41 moves downward to perform hot stamping on the lower surface of the cosmetic box 0, and then the electric telescopic rod 12 is started to drive the push block 13 to move backward and push out of the groove 272, so that the movable frame 6 is disconnected from the U-shaped table 2, and under the elastic force of the fifth spring 61, the movable frame 6 will return to its initial state; Such a design can achieve the hot stamping work on the lower surface of the cosmetic box 0 during the movement of the chain conveyor 1, reduce the stop time of the chain conveyor 1, and improve the processing efficiency of the device.

[0023] The bottom of the moving frame 6 is provided with sliding wheels; the sliding wheels can reduce the friction between the moving frame 6 and the machine table 11, making it slide more smoothly.
