Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging box technology, specifically, it relates to a hot stamping device for cosmetic packaging boxes. Background Technology

[0002] Cosmetic packaging boxes are an indispensable part of the cosmetics industry. Besides protecting the product, they also carry the brand image and product information. Meanwhile, the hot stamping process on cosmetic packaging boxes is a crucial step in enhancing the product's appearance and brand recognition. The packaging boxes must be precisely fed to the hot stamping station to ensure that the hot stamped patterns and text are accurately printed in the preset positions. This avoids misalignment, excessively light or dark stamping due to feeding deviations, which would affect the product's aesthetics and market competitiveness. Stable feeding ensures the continuity and precision of the hot stamping process, thereby improving the production quality of cosmetic packaging boxes.

[0003] Currently, in existing hot stamping equipment, during the feeding process, the cosmetic packaging box moves to the hot stamping station along the conveyor belt. When the hot stamping plate at the hot stamping station applies downward pressure to the cosmetic packaging box under hydraulic drive, the conveyor belt of the existing hot stamping equipment can only move horizontally and cannot provide stable support for the cosmetic packaging box in the vertical direction. This causes the cosmetic packaging box to shift downward under pressure, resulting in uneven force between the hot stamping plate and the cosmetic packaging box, leading to problems such as local hot stamping being too shallow or too deep, thereby reducing the quality of hot stamping.

[0012] According to one embodiment of the present invention, the rubber-coated wheel support mechanism includes a support base, two rubber-coated wheel fixing plates, and multiple rubber-coated wheels; the support base is disposed on the frame, the two rubber-coated wheel fixing plates are symmetrically disposed on the support base in the horizontal direction, and the multiple rubber-coated wheels are rotatably disposed between the two rubber-coated wheel fixing plates at intervals, and the multiple rubber-coated wheels support multiple material-carrying fixtures located on the belt.

[0015] The beneficial effects of this application are as follows: The hot stamping device for cosmetic packaging boxes of this application uses a drive unit to rotate a belt. During the rotation of the belt, multiple material carriers move stably along the conveyor channel. The cosmetic packaging boxes are initially positioned by the limiting grooves on the top of the material carriers, ensuring that the cosmetic packaging boxes do not shift during horizontal conveying. When the material carriers move to the bottom of the hot stamping mechanism, the hot stamping positioning mechanisms symmetrically distributed on both sides of the conveyor channel push the positioning components into the positioning grooves of the material carriers through the positioning drive, achieving secondary positioning of the material carriers in the horizontal direction until they reach the hot stamping mechanism, further ensuring the accurate positioning of the cosmetic packaging boxes during the hot stamping process. After the secondary positioning is completed, the hot stamping mechanism begins to apply a downward force to the cosmetic packaging boxes on the material carriers to perform hot stamping. At this time, since multiple support bearings are located within the space enclosed by the belt, the support bearings provide stable vertical support from the bottom of the material carriers, relieving the downward pressure applied by the hot stamping mechanism and preventing the material carriers and cosmetic packaging boxes from shifting downward. Compared to traditional hot stamping devices that rely solely on conveyor belts and lack stable support, this application can instantly provide positioning and support for cosmetic packaging boxes during the hot stamping process. This ensures uniform force distribution between the hot stamping plate and the cosmetic packaging box, effectively preventing issues such as shallow hot stamping in certain areas caused by downward displacement of the material jig and cosmetic packaging box, or excessive hot stamping caused by continuous downward pressure from the hot stamping mechanism. This significantly improves the quality of hot stamping. Attached Figure Description

[0034] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:

[0035] like Figure 1 As shown, Figure 1 This is a three-dimensional structural diagram of the hot stamping device for cosmetic packaging boxes in this embodiment. This embodiment provides a hot stamping device for cosmetic packaging boxes, including a frame 1, a feeding mechanism 2, a hot stamping mechanism 3, and a discharging mechanism 4. The feeding mechanism 2, hot stamping mechanism 3, and discharging mechanism 4 are all mounted on the frame 1. The feeding mechanism 2 is horizontally mounted on the frame 1, the hot stamping mechanism 3 is located on one side of the feeding mechanism 2, and the discharging mechanism 4 is located at the end of the feeding mechanism 2 away from the feeding start end. The feeding mechanism 2 is used to carry and orderly transport cosmetic packaging boxes to the hot stamping mechanism 3, where the hot stamping mechanism 3 performs hot stamping on the cosmetic packaging boxes. The discharging mechanism 4 transfers the hot stamped cosmetic packaging boxes and unloads them into a subsequent collection area. After the hot stamping operation is completed with the hot stamping mechanism 3, the discharging mechanism 4 unloads the cosmetic packaging boxes, thereby improving the hot stamping quality and production efficiency.

[0036] Please refer to the following: Figure 2-6 As shown, Figure 2 This is a three-dimensional structural diagram of the feeding mechanism in the embodiment; Figure 3 This is a three-dimensional structural diagram of the transmission drive component in the embodiment; Figure 4 This is a three-dimensional structural diagram of the support mechanism in the embodiment; Figure 5 This is a three-dimensional structural diagram of the material-carrying fixture in the embodiment; Figure 6 This is a three-dimensional structural diagram of the hot stamping positioning mechanism in the embodiment. The feeding mechanism 2 includes a conveying bracket 21, a conveying drive assembly 22, a support mechanism 23, multiple material-carrying fixtures 24, and multiple hot stamping positioning mechanisms 25. The conveying bracket 21 is mounted on the frame 1. The conveying drive assembly 22 includes a mounting frame 221, a drive unit 222, and a belt 223. The mounting frame 221 is mounted on the conveying bracket 21 and has a conveying channel 2210. The drive unit 222 is located at both ends of the mounting frame 221. The belt 223 is wound around the drive unit 222 and located in the conveying channel 2210. Multiple material-carrying fixtures 24 are evenly spaced on the belt 223. Each material-carrying fixture 24 has a limiting groove 2401 at its top and a positioning groove 2402 at its bottom.

[0037] The conveyor support 21 is mounted on the frame 1, providing the mounting base for the entire feeding mechanism 2. The conveyor drive assembly 22 includes a mounting frame 221, a drive unit 222, and a belt 223. The mounting frame 221 is fixed to the conveyor support 21, and the mounting frame 221 has a conveying channel 2210 along its length, providing space for the movement of the belt 223 and the material-carrying fixture 24. The drive unit 222 is located at both ends of the mounting frame 221, and the belt 223 is wound around the drive unit 222 and located in the conveying channel 2210. The drive unit 222 drives the belt 223 to move cyclically along the length of the conveying channel 2210. The conveyor channel 2210 provides guidance for the movement of the material carrier 24; multiple material carriers 24 are evenly fixed on the belt 223 along the length of the belt 223 and move synchronously with the belt 223. Each material carrier 24 has a limiting groove 2401 at the top. The shape and size of the limiting groove 2401 are adapted to the shape of the cosmetic packaging box to be hot-stamped, so that the cosmetic packaging box can be stably embedded in the limiting groove 2401 to prevent the packaging box from shifting horizontally during the conveying process; each material carrier 24 has a positioning groove 2402 at the bottom. The positioning groove 2402 is used to cooperate with the hot-stamping positioning mechanism 25 to achieve precise positioning of the material carrier 24 at the hot-stamping station.

[0038] Please review Figure 2 and Figure 4-5The support mechanism 23 includes a support frame 231 and multiple support bearings 232. The support frame 231 is fixed on the frame 1, and the multiple support bearings 232 are rotatably connected to the support frame 231 in parallel. The support bearings 232 are located in the space enclosed by the belt 223. When the belt 223 drives the multiple material carriers 24 to rotate, the material carriers 24 pass over the support bearings 232.

[0039] The support frame 231 is fixed on the frame 1 and is arranged along the width direction of the mounting frame 221, located directly below the conveyor channel 2210 facing the hot stamping mechanism 3. Multiple support bearings 232 are rotatably connected to the top of the support frame 231 along the length direction of the support frame 231, and the support bearings 232 are located in the space enclosed by the belt 223. When the belt 223 drives multiple material carriers 24 to rotate to the vicinity of the hot stamping mechanism 3, the bottom of the material carrier 24 contacts the top of the support bearing 232, and the support bearing 232 can provide stable support for the material carrier 24 above. This design effectively addresses the shortcomings of existing devices. Specifically, when the hot stamping mechanism 3 applies downward hot stamping pressure to the cosmetic packaging box within the material carrier fixture 24, the support bearing 232 provides upward support from the bottom of the material carrier fixture 24, counteracting the hot stamping pressure and preventing downward displacement of the material carrier fixture 24 and the cosmetic packaging box under pressure. This ensures uniform contact and force between the hot stamping mechanism 3 and the cosmetic packaging box, preventing issues such as excessively shallow or deep hot stamping in certain areas, and significantly improving the hot stamping quality. Simultaneously, the support bearing 232 rotates synchronously with the movement of the material carrier fixture 24, reducing frictional resistance between the material carrier fixture 24 and the support mechanism 23, ensuring smooth conveying.

[0040] Please review Figure 2 and Figure 6 Multiple hot stamping positioning mechanisms 25 are mounted on the mounting frame 221 and symmetrically distributed on both sides of the conveying channel 2210. Each hot stamping positioning mechanism 25 includes a positioning drive 251 and a positioning component 252. The positioning drive 251 is fixed to the mounting frame 221, and the positioning component 252 is mounted on the positioning drive 251. The positioning component 252 faces the material loading fixture 24 located above the support bearing 232, and the positioning component 252 is adapted to the positioning groove 2402.

[0041] The positioning drive component 251 is fixed to the side of the mounting bracket 221, and the positioning component 252 is disposed on the positioning drive component 251. The positioning component 252 faces the material carrier 24 located above the support bearing 232, and the shape and size of the positioning component 252 are adapted to the positioning groove 2402. When the material carrier 24 moves to the hot stamping mechanism 3 with the belt 223, the positioning drive component 251 drives the positioning component 252 to move towards the material carrier 24, so that the positioning component 252 is engaged in the positioning groove 2402 at the bottom of the material carrier 24, thereby performing secondary limiting and fixing of the material carrier 24 in the horizontal direction, preventing the material carrier 24 from shifting horizontally during the hot stamping process, and further ensuring the accuracy of hot stamping.

[0042] Please review Figure 1 The hot stamping mechanism 3 is mounted on the frame 1 and faces the support bearing 232; the unloading mechanism 4 is mounted on the frame 1 and located at the end of the loading mechanism 2. The hot stamping mechanism 3, being mounted on the frame 1 and located on one side of the mounting bracket 221, faces the support bearing 232, allowing it to perform hot stamping on cosmetic packaging boxes within the limiting groove 2401 of the material carrier 24 above the support bearing 232. As the material carrier 24 completes its positioning, the hot stamping mechanism 3 moves downwards and contacts the cosmetic packaging box within it, completing the hot stamping operation. The unloading mechanism 4, mounted on the frame 1 and located at the end of the loading mechanism 2, picks up the hot-stamped cosmetic packaging box from the material carrier 24 and transfers it to a subsequent storage area after hot stamping, thus achieving automated unloading.

[0043] For further details, please review. Figure 3 The drive unit 222 includes a drive motor 2221, a drive shaft wheel 2222, and a driven shaft wheel 2223.

[0044] The drive motor 2221 is fixed to one end of the mounting frame 221 by a bracket. The output end of the drive motor 2221 extends horizontally. The two ends of the drive shaft wheel 2222 are rotatably connected to the inner wall of one end of the mounting frame 221 by bearings. The drive shaft wheel 2222 is then fixed to the output end of the drive motor 2221. The driven shaft wheel 2223 is rotatably mounted on the inner wall of the other end of the mounting frame 221 by bearings. The belt 223 is wound between the drive shaft wheel 2222 and the driven shaft wheel 2223 and is located in the conveying channel 2210. The outer surface of the belt 223 and the fixing plate 241 of the material loading fixture 24 are fixedly connected by bolts or other fasteners. When the drive motor 2221 starts, the output end drives the drive shaft wheel 2222 to rotate. The drive shaft wheel 2222 rotates the slave shaft wheel 2223 via the belt 223, thereby realizing the cyclic movement of the belt 223 along the length of the conveying channel 2210, providing a stable and continuous conveying for the material jig 24.

The fixture body 242 is fixed to the fixing plate 241 by bolts. The top of the fixture body 242 has a limiting groove 2401 along the thickness direction, which is used to stably embed the cosmetic packaging box in the limiting groove 2401 to prevent the packaging box from shifting horizontally during transportation. Both ends of the fixing plate 241 are provided with multiple positioning grooves 2402. The positioning grooves 2402 are U-shaped groove structures, symmetrically opened on both sides of the fixing plate 241. They can work together with the positioning parts 252 on the hot stamping positioning mechanism 25 on both sides of the mounting frame 221 to achieve bidirectional positioning and improve positioning stability.

[0046] For further details, please review. Figure 6The positioning drive component 251 includes a cylinder fixing plate 2511, a drive cylinder 2512, and a positioning slider 2513. The cylinder fixing plate 2511 is mounted on the mounting bracket 221, the drive cylinder 2512 is located on one side of the cylinder fixing plate 2511, and the positioning slider 2513 is located on the other side of the cylinder fixing plate 2511. The positioning slider 2513 has an embedded cavity 25130. The positioning component 252 includes a connecting block 2521 and multiple positioning protrusions 2522. The connecting block 2521 is located in the embedded cavity 25130 and connected to the output end of the drive cylinder 2512. One end of the multiple positioning protrusions 2522 is connected to the connecting block 2521, and the other end protrudes through the positioning slider 2513. The drive cylinder 2512 drives the connecting block 2521 to move in the embedded cavity 25130. The connecting block 2521 drives the positioning protrusions 2522 to slide relative to the positioning slider 2513. The positioning protrusions 2522 are adapted to the positioning groove 2402.

[0047] The cylinder fixing plate 2511 is fixed to the side of the mounting bracket 221 by bolts; the drive cylinder 2512 is arranged horizontally on one side of the cylinder fixing plate 2511, the cylinder body of the drive cylinder 2512 is fixed on the cylinder fixing plate 2511, and the piston rod faces the conveying channel 2210; the positioning slider 2513 is arranged on the other side of the cylinder fixing plate 2511 opposite to the drive cylinder 2512, and an embedded cavity 25130 is opened horizontally on the positioning slider 2513, the extension direction of the embedded cavity 25130 is consistent with the extension and retraction direction of the piston rod of the drive cylinder 2512. The positioning component 252 includes a connecting block 2521 and a plurality of positioning protrusions 2522. The connecting block 2521 is rectangular and is located in the inner cavity 25130 and is connected to the piston rod end of the drive cylinder 2512 by bolts. The plurality of positioning protrusions 2522 are spaced apart in the vertical direction. One end of the positioning protrusion 2522 is integrally formed with the connecting block 2521 or fixedly connected by bolts, and the other end extends out of the positioning slider 2513 in the horizontal direction toward the material loading fixture 24. The end shape of the positioning protrusion 2522 is adapted to the U-shaped groove of the positioning groove 2402. When the material carrier fixture 24 moves to the hot stamping station, the piston rod of the drive cylinder 2512 extends, driving the connecting block 2521 to slide horizontally in the inner cavity 25130. The connecting block 2521 drives the positioning protrusion 2522 to slide synchronously relative to the positioning slider 2513, so that the end of the positioning protrusion 2522 is engaged in the positioning groove 2402 at the bottom of the material carrier fixture 24, realizing the horizontal positioning of the material carrier fixture 24. After the hot stamping is completed, the piston rod of the drive cylinder 2512 retracts, driving the positioning protrusion 2522 to disengage from the positioning groove 2402, releasing the positioning, and the material carrier fixture 24 can continue to move to the unloading mechanism 4 with the belt 223.

[0049] Furthermore, each cam bearing mechanism 26 includes a bearing fixing plate 261 and a plurality of cam bearings 262; the bearing fixing plate 261 is mounted on the mounting frame 221, the plurality of cam bearings 262 are rotatably mounted on the bearing fixing plate 261 at intervals and located in the conveying channel 2210, and the bottoms of the plurality of material loading fixtures 24 located above the mounting frame 221 are supported on the cam bearings 262. The bearing fixing plate 261 is L-shaped and fixed to the inner wall of the mounting frame 221. Multiple cam bearings 262 are rotatably connected to the bearing fixing plate 261 at intervals along the length of the bearing fixing plate 261. The top of the cam bearings 262 is higher than the inner wall of the mounting frame 221. The bottom sides of the multiple material carriers 24 located above the mounting frame 221 are in contact with the top of the cam bearings 262 on both sides. The cam bearings 262 provide horizontal support to the material carriers 24 from both sides, further preventing the material carriers 24 from swaying horizontally during the conveying process. At the same time, the cam bearings 262 can rotate synchronously with the material carriers 24 to reduce frictional resistance.

[0050] For further details, please review. Figure 2 And refer to them together Figure 8 As shown, Figure 8 This is a three-dimensional structural diagram of the rubber-coated wheel support mechanism in the embodiment. The feeding mechanism 2 also includes a rubber-coated wheel support mechanism 28; the rubber-coated wheel support mechanism 28 is disposed on the frame 1, and the tops of the multiple material-carrying jigs 24 located below the mounting frame 221 are supported on the rubber-coated wheel support mechanism 28. That is, the rubber-coated wheel support mechanism 28 is located in the return section of the multiple material-carrying jigs 24 below the mounting frame 221. This return section is the section in which the multiple material-carrying jigs 24, after completing the unloading, are driven by the belt 223 to move downward from one end of the mounting frame 221, around the driven shaft wheel 2223, and towards the drive shaft wheel 2222 at the other end of the mounting frame 221.

[0051] Furthermore, the rubber-coated wheel support mechanism 28 includes a support base 281, two rubber-coated wheel fixing plates 282, and multiple rubber-coated wheels 283; the support base 281 is mounted on the frame 1, the two rubber-coated wheel fixing plates 282 are symmetrically mounted on the support base 281 in the horizontal direction, and the multiple rubber-coated wheels 283 are rotatably mounted between the two rubber-coated wheel fixing plates 282 at intervals, and the multiple rubber-coated wheels 283 support multiple material-carrying fixtures 24 located on the belt 223. The support base 281 has a frame structure and is fixed to the frame 1 with bolts. The support base 281 is arranged along the length of the mounting frame 221 and is located directly below the multiple material-carrying fixtures 24 on the belt 223. Two rubber-coated wheel fixing plates 282 are long strips and are symmetrically arranged on the top sides of the support base 281 in the horizontal direction, with an installation gap between the two rubber-coated wheel fixing plates 282. Multiple rubber-coated wheels 283 are spaced apart along the length of the rubber-coated wheel fixing plates 282. The two ends of the rubber-coated wheels 283 are rotatably connected between the two rubber-coated wheel fixing plates 282 through bearings. The multiple rubber-coated wheels 283 are located on top of the multiple material-carrying fixtures 24 on the belt 223 below the mounting frame 221, that is, the fixture body 2. The top of 42 contacts the outer peripheral surface of the rubber-coated wheel 283. The rubber-coated wheel 283 provides upward support to the corresponding material-carrying fixture 24 from above, preventing the belt 223 from sag downward due to the weight of the material-carrying fixture 24. This ensures that the belt 223 can maintain a horizontal transmission state during the return stroke, thereby ensuring smooth transmission of the entire transmission drive assembly 22. At the same time, the outer peripheral surface of the rubber-coated wheel 283 is covered with a wear-resistant elastic rubber layer, which can buffer the contact impact between the material-carrying fixture 24 and the rubber-coated wheel 283, reduce the collision wear between the two, extend the service life of the material-carrying fixture 24 and the rubber-coated wheel 283, and the friction of the elastic rubber layer can assist the belt 223 in transmission and prevent the belt 223 from slipping.

The pattern of the hot stamping heating lower template is consistent with the hot stamping pattern of the cosmetic packaging box. The hot stamping heating assembly 33 faces the material carrier 24 located above the support bearing 232. After the material carrier 24 is positioned, the hot stamping drive assembly 32 drives the hot stamping heating assembly 33 to move downward, so that the hot stamping heating lower template contacts the surface of the cosmetic packaging box in the material carrier 24 and applies a set pressure. At the same time, the hot stamping heating plate heats the hot stamping heating lower template. After the hot stamping operation is completed, the hot stamping drive assembly 32 drives the hot stamping heating assembly 33 to return to its original position.

Simultaneously, the precise cooperation between the hot stamping positioning mechanism 25 and the positioning groove 2402 on the material carrier fixture 24, combined with the auxiliary support of the cam bearing mechanism 26 on both horizontal sides, further ensures the stability of the material carrier fixture 24 at the hot stamping mechanism 3, thereby improving the alignment accuracy of the hot stamping process. Furthermore, the dust removal hood 27 can remove dust and impurities from the surface of the cosmetic packaging box in real time, preventing foreign objects from affecting the hot stamping effect and further ensuring the cleanliness and aesthetics of the hot stamped surface.
