[0003] The above-mentioned patents have the following shortcomings:

[0004] Since the hot stamping position on the packaging box is usually located in a fixed position on the warranty box, and there are no limiters on both sides of the warranty box when the packaging box is conveyed on the conveyor belt, it is impossible to guarantee that the printed hot stamping position on the warranty box is directly below the hot stamping mechanism, which can easily lead to deviations in the hot stamping position. Utility Model Content

[0005] In view of the problems existing in a packaging box printing hot stamping machine, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a packaging box printing hot stamping machine, which solves the problem in the above-mentioned patent that the hot stamping position on the packaging box is usually located at the fixed position of the warranty box. However, when the packaging box is conveyed on the conveyor belt, there are no limit positions on both sides of the warranty box, so it is impossible to ensure that the printing hot stamping position of the warranty box is directly below the hot stamping mechanism, which easily leads to the hot stamping position deviation.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A hot stamping machine for packaging box printing includes two support plates, a conveying mechanism installed between the two support plates, a hot stamping mechanism installed on both support plates, and an adjusting limit mechanism installed on each support plate. The two sets of adjusting limit mechanisms limit the two ends of the packaging box located on the conveying mechanism.

[0009] In a preferred embodiment of the packaging box printing hot stamping machine described in this utility model, both ends of the two support plates are connected to a bridging bottom support plate.

[0010] In a preferred embodiment of the packaging box printing hot stamping machine of this utility model, the conveying mechanism includes a first transmission roller and a second transmission roller that are rotatably connected to two support plates via bearings, and the first transmission roller and the second transmission roller are connected to a conveyor belt for common transmission.

[0011] As a preferred embodiment of the packaging box printing hot stamping machine of this utility model, the hot stamping mechanism includes a U-shaped support frame welded to two support plates, an electric push rod is installed on the U-shaped support frame, and a hot stamping plate is installed at the bottom of the electric push rod.

[0012] As a preferred embodiment of the packaging box printing hot stamping machine of this utility model, the bottom of the U-shaped support frame is welded with a first support connecting seat, the top end of the first electric push rod is inserted into the first support connecting seat, and the corresponding positions of the first support connecting seat and the first electric push rod are provided with internal threaded holes, and the first support connecting seat and the electric push rod are fixed together by bolts.

[0013] The top of the hot stamping plate is welded with a second support connector. A first electric push rod is inserted into the inner wall of the second support connector. The first electric push rod and the second support connector are both provided with internal threaded holes at corresponding positions, and the electric push rod and the second support connector are fixed together by bolts.

[0014] In a preferred embodiment of the packaging box printing hot stamping machine of this utility model, the adjusting and limiting mechanism includes a U-shaped support block welded to a support plate, a second electric push rod installed on the U-shaped support block, and a limiting plate installed at the other end of the second electric push rod.

[0015] In a preferred embodiment of the packaging box printing hot stamping machine described in this utility model, a plurality of rollers are installed on the limiting plate.

[0016] Compared with existing technologies:

[0017] By setting an adjustable limiting mechanism on the support plates on both sides, the position of the two limiting plates can be adjusted, thereby limiting the two sides of the packaging box. This ensures that when the packaging box is transported to the bottom of the hot stamping mechanism, the hot stamping position on the packaging box is directly below the hot stamping mechanism, thus ensuring the accuracy of the hot stamping position and avoiding hot stamping position deviation.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example

[0025] This utility model provides a hot stamping machine for printing packaging boxes. Please refer to [link / reference]. Figure 1-4 It includes two support plates 1, a conveying mechanism is installed between the two support plates 1, a hot stamping mechanism is installed on both support plates 1, and an adjustment and limiting mechanism is installed on each of the two support plates 1. The two sets of adjustment and limiting mechanisms limit the two ends of the packaging box located on the conveying mechanism.

[0026] Both ends of the two support plates 1 are connected to a bridging bottom support plate 12.

[0027] The conveying mechanism includes a first transmission roller 10 and a second transmission roller 13 that are rotatably connected to the two support plates 1 via bearings. The first transmission roller 10 and the second transmission roller 13 are connected to a conveyor belt 11 for transmission. One end of the first transmission roller 10 or the second transmission roller 13 is connected to the output shaft of a servo motor via a coupling. The servo motor is mounted on the support plate 1.

[0028] The hot stamping mechanism includes a U-shaped support frame 2 welded to two support plates 1. A first electric push rod 4 is installed on the U-shaped support frame 2. Specifically, a first support connecting seat 3 is welded to the bottom of the U-shaped support frame 2. The top end of the first electric push rod 4 is inserted into the first support connecting seat 3. Internal threaded holes are opened at corresponding positions of the first support connecting seat 3 and the first electric push rod 4. The first support connecting seat 3 and the first electric push rod 4 are fixed together by bolts. A hot stamping plate 6 is installed at the bottom of the first electric push rod 4. Specifically, a second support connecting seat 5 is welded to the top end of the hot stamping plate 6. The first electric push rod 4 is inserted into the inner wall of the second support connecting seat 5. Internal threaded holes are opened at corresponding positions of the first electric push rod 4 and the second support connecting seat 5 are fixed together by bolts.

[0029] The adjusting limiting mechanism includes a U-shaped support block 7 welded to the support plate 1. A second electric push rod 8 is installed on the U-shaped support block 7. Specifically, a fourth support connecting seat 16 is welded to the U-shaped support block 7. The second electric push rod 8 is inserted into the inner wall of the fourth support connecting seat 16. The second electric push rod 8 and the fourth support connecting seat 16 are fixed together by bolts. A limiting plate 9 is installed at the other end of the second electric push rod 8. Specifically, a third support connecting seat 14 is welded to the limiting plate 9. The second electric push rod 8 is inserted into the inner wall of the third support connecting seat 14 and fixed together by bolts. A through hole is provided on the support plate 1 for the second electric push rod 8 to pass through. The end of the limiting plate 9 is arc-shaped, and the distance between the arc-shaped parts on the two limiting plates 9 is larger, thereby ensuring that the packaging box can smoothly enter between the two limiting plates 9.

[0030] In practical use, depending on the location where hot stamping is required on the packaging box, the positions of the two limiting plates 9 are adjusted by extending and retracting the two second electric push rods 8, so that the distance between the two limiting plates 9 is slightly greater than the width of the packaging box, and ensures that when the packaging box is transported to the bottom of the hot stamping plate 6, the hot stamping position of the packaging box is directly below the hot stamping plate 6.

[0031] The packaging box is placed on the conveyor belt 11 and is limited between the two limiting plates 9 until it is conveyed to the bottom of the hot stamping mechanism, where the hot stamping mechanism performs the hot stamping operation on the packaging box. Example

[0032] See attached document Figure 5Unlike embodiment 1, the limiting plate 9 is equipped with multiple rollers 15. When the rollers are positioned between the packaging box and the box, the rollers 15 can rotate, thus preventing the packaging box from getting stuck.
