Description

Technical Field

[0001] This utility model relates to the field of packaging gift box processing technology, specifically an automatic packaging gift box laminating machine. Background Technology

[0002] As the core carrier for product display and protection, the surface coating treatment of gift boxes can significantly improve wear resistance, water resistance and visual texture, which is a key process in gift box production.

[0003] A search revealed that patent document CN202220797221.6 discloses an "automatic laminating mechanism for a laminating machine," which includes a second fixed long block. The left and right sides of the second fixed long block are fixedly connected to first support columns. This automatic laminating mechanism for a laminating machine achieves the purpose of automatic cutting and can make the lamination tighter, thus having great practicality.

[0004] This patent has some problems in actual use. It uses a bottom support and a cutter to cut the film. First, the downward cutting method is not easy to cut the material, and it is very easy to produce partial cuts and partial connections. It requires manual secondary trimming, which increases the process and cost. Second, it cannot cut customized shapes according to market demand (such as wavy edges for holiday gift boxes and serrated edges for cultural and creative gift boxes), which limits its practicality and makes it difficult to meet the differentiated production needs of high-end gift boxes. Utility Model Content

[0005] The purpose of this invention is to provide an automatic laminating machine for gift boxes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic laminating machine for gift boxes, comprising two frame plates, with reinforcing rods welded to the four corners of opposite sides. Symmetrical bearing seats are mounted on the outer sides of the frame plates, and a rotating shaft is rotatably connected between the two opposing bearing seats. A laminating roller is mounted on the surface of the rotating shaft at a position corresponding to the two frame plates. A connecting plate is fixedly mounted on the bottom of the frame plates at the right side corresponding to the laminating roller. A support roller is rotatably connected between the two connecting plates. A primary drive mechanism is fixedly mounted on the bottom of the two frame plates at the right side corresponding to the support roller. A secondary drive mechanism is fixedly mounted on the moving end of the primary drive mechanism.

[0007] Furthermore, the primary drive mechanism includes a bracket, with both ends of the bracket fixedly connected to the bottom of two frame plates respectively. A stepper motor is fixedly installed on the outer side of the bracket, and the output shaft of the stepper motor passes through to the inner side of the bracket and is fixedly connected to a screw. A translation block is threaded along the axial direction on the screw. A guide sleeve is fixedly connected to the right side of the translation block through a frame rod. The guide sleeve is slidably connected to the bracket. Connecting rods are symmetrically installed on the left side of the translation block.

[0008] Furthermore, the secondary drive mechanism includes a movable housing, which is fixedly installed at one end of two connecting rods. An electric push rod is fixedly installed on the top of the movable housing. The telescopic end of the electric push rod extends through the interior of the movable housing and is fixedly connected to a lifting block. The left side of the lifting block extends through the exterior of the movable housing and is fixedly connected to a mounting plate. A laser cutting device is fixedly connected to the left side of the mounting plate.

[0009] Furthermore, a rolling bearing is fixedly installed on one side of the inner wall of the bracket at the position corresponding to the screw, and one end of the screw passes through the inside of the rolling bearing and is movably connected to it.

[0010] Furthermore, a number of ball bearings are movably installed on the inner side of the guide sleeve, and guide wheels are symmetrically installed on both sides of the lifting block, with the guide wheels rollingly connected to the inner wall of the movable shell.

[0011] Furthermore, a microcontroller is fixedly installed on the inner side of one of the frame plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention fixes the frame plate onto the laminating machine, thus securing the laminating mechanism. After lamination using two laminating rollers, the cardboard is supported and guided by the support rollers. During cutting, the microcontroller simultaneously controls the start of the stepper motor and the electric push rod according to the required cutting shape. After the stepper motor is turned on, its output shaft drives the screw to rotate. The translation block threaded onto it can drive the laser cutting device to move horizontally under the guidance of the frame rod and the guide sleeve. Similarly, the telescopic end of the electric push rod can drive the laser cutting device to move vertically. By adjusting the horizontal and vertical movement range and speed, different shapes of cuts can be formed by laser cutting. The equipment uses laser cutting to cut the film, which can completely solve the problem of film adhesion, eliminating the need for secondary trimming, effectively reducing processing steps and costs. At the same time, the cutting path can be customized according to market demand, improving practicality and meeting the differentiated needs of high-end gift boxes. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 An automatic gift box laminating machine includes two frame plates 1. The four corners of the two frame plates 1 on opposite sides are welded together with reinforcing rods 2. The frame plates 1 can be fixed to the laminating machine by welding mounting rods or by creating screw holes. The method for fixing the laminating mechanism is a mature existing technology and will not be elaborated here. Shaft seats 3 are symmetrically installed on the outer side of the frame plates 1. A rotating shaft 4 is rotatably connected between the two opposing shaft seats 3. A laminating roller 5 is installed on the surface of the rotating shaft 4 at a position corresponding to the two frame plates 1. The laminating roller 5 enables the laminating of objects. Materials and film can be inserted between the two laminating rollers 5. A connecting plate 6 is fixedly installed at the bottom of the frame plates 1, corresponding to the right side of the laminating roller 5. A support roller 7 is rotatably connected between the two connecting plates 6. The support roller 7 is used to support and guide the laminated gift box cardboard. The distance between the top of the support roller 7 and the bottom of the laminating roller 5 can be adjusted by adding or removing bearing shims to accommodate gift box cardboard of different thicknesses, ensuring that the laminated gift box is conveyed horizontally.

[0017] A primary drive mechanism 8 is fixedly installed at the bottom of the two support plates 1 and on the right side corresponding to the support roller 7. The primary drive mechanism 8 includes a bracket 81. A stepper motor 82 is fixedly installed on the outside of the bracket 81. The output shaft of the stepper motor 82 passes through the inside of the bracket 81 and is fixedly connected to a screw 83. A rolling bearing 88 is fixedly installed on one side of the inner wall of the bracket 81 at the position corresponding to the screw 83. One end of the screw 83 passes through the inside of the rolling bearing 88 and transitions with it. The rolling bearing 88 can connect and support one end of the screw 83, improving the smoothness during rotation. A translation block 84 is threaded along the axial direction on the screw 83. A guide sleeve 86 is fixedly connected to the right side of the translation block 84 through a bracket rod 85. Several balls 89 are movably installed on the inner side of the guide sleeve 86. The balls 89 reduce the friction and wear generated on the inner side of the guide sleeve 86 when it moves. A connecting rod 87 is symmetrically installed on the left side of the translation block 84.

[0018] A secondary drive mechanism 9 is fixedly installed on the moving end of the primary drive mechanism 8. The secondary drive mechanism 9 includes a moving shell 91. An electric push rod 92 is fixedly installed on the top of the moving shell 91. Its telescopic end extends through the interior of the moving shell 91 and is fixedly connected to a lifting block 93. Nylon guide wheels 96 are symmetrically installed on both sides of the lifting block 93 and are rolled to the inner wall of the moving shell 91 to restrict the lifting block 93 to move only in the vertical direction and avoid lateral deviation. A mounting plate 94 is fixedly connected to the left side of the lifting block 93 extending through the exterior of the moving shell 91. A laser cutting device 95 is fixedly connected to the left side of the mounting plate 94. The laser cutting device 95 is a small CO2 laser cutting head that supports setting various cutting paths such as straight lines, wavy lines, and serrated lines through software.

[0019] One of the mounting plates 1 has a microcontroller 10 fixedly installed on its inner side. The microcontroller 10 is an STM32F407VET6 microcontroller, which is electrically connected to the stepper motor 82, the electric push rod 92, and the laser cutting device 95.

[0020] In use, after fixing the frame plate 1 onto the laminating machine, the laminating mechanism is fixed. After laminating with two laminating rollers 5, the cardboard is supported and guided by the support roller 7. During cutting, the microcontroller 10 can simultaneously control the start of the stepper motor 82 and the electric push rod 92 according to the cutting shape requirements. After the stepper motor 82 is turned on, its output shaft can drive the screw 83 to rotate. The translation block 84 threaded onto it can drive the laser cutting device 95 to move horizontally under the connection and guidance of the frame rod 85 and the guide sleeve 86. Similarly, the telescopic end of the electric push rod 92 can drive the laser cutting device 95 to move vertically. By adjusting the horizontal and vertical movement range and speed, different shapes of cuts can be formed by laser cutting.
