Description

Technical Field

[0001] This utility model relates to the field of laser cardboard processing technology, specifically to a laser cardboard transfer molding device. Background Technology

[0002] In the fields of packaging printing and decorative materials, holographic cardboard is highly favored for its dazzling optical effects, and the molding process is a key step in giving holographic cardboard its special patterns and optical properties. Existing holographic cardboard molding devices mostly focus on the structural design and performance optimization of the molding mechanism itself, but generally neglect the fixation of the holographic cardboard. In actual molding processes, due to the lack of an effective fixing structure, the holographic cardboard is prone to shifting and wrinkling under molding pressure, leading to problems such as misalignment and ghosting of the molded pattern, seriously affecting product quality and production efficiency. Furthermore, the lack of a fixing structure also makes it difficult to accurately position the holographic cardboard when it is fed into the molding device, increasing the workload and difficulty of manual adjustment, and hindering automated and large-scale production.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0004] The purpose of this invention is to provide a transfer laser cardboard molding device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a transfer laser card molding device, including a bracket, a support column installed on the top surface of the bracket, a top plate installed on the support column, a hydraulic cylinder installed on the top plate, a movable template connected to the telescopic end of the hydraulic cylinder, a fixed template corresponding to the movable template installed on the top surface of the bracket, a groove opened on the top surface of the fixed template, a bearing plate installed inside the groove, a distribution air channel and a main air channel opened inside the bearing plate, an air hole communicating with the distribution air channel opened on the top surface of the bearing plate, and a negative pressure pump installed on the bottom surface of the bracket, the negative pressure end of the negative pressure pump communicating with the main air channel.

[0006] Furthermore, a control switch is installed on the bracket, and the control switch is electrically connected to the negative pressure pump.

[0007] Furthermore, a guide plate is installed on the top wall of the movable template, and a guide rod is installed on the top surface of the guide plate, the guide rod being slidably connected to the top plate.

[0008] Furthermore, four pillars are provided, and the four pillars are respectively located at the four corners of the top surface of the support.

[0009] Furthermore, multiple air holes are provided, and the multiple air holes are distributed in a rectangular array on the support plate.

[0010] Furthermore, a dustproof membrane is installed inside the vent, and a cross-shaped cut is made on the dustproof membrane.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting up a fixed structure consisting of a support plate, distribution air channels, main air channels, air holes, and a negative pressure pump, effectively solves the problems of misalignment and wrinkling that easily occur in the molding process of laser cardstock due to the lack of a fixed structure in the prior art. During the molding process, the laser cardstock is firmly adsorbed onto the support plate and will not move arbitrarily due to molding pressure. This allows the molded pattern to be accurately printed on the cardstock, avoiding quality problems such as pattern misalignment and ghosting, greatly improving product quality and meeting the market demand for high-quality laser cardstock.

[0013] 2. In this invention, multiple air holes are arranged in a rectangular array on the support plate, allowing the laser card to be subjected to a more uniform negative pressure adsorption force, further optimizing the fixing effect of the laser card and ensuring the stability of the card during the molding process. Simultaneously, the dustproof membrane with cross-cuts installed inside the air holes effectively prevents dust and other impurities from entering the air passages while ensuring the normal operation of the device, reducing the risk of air passage blockage, decreasing the frequency of equipment cleaning and maintenance due to air passage blockage, and improving the operational reliability and production continuity of the equipment.

[0019] 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.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a transfer laser card molding device, including a support 1, a support column 2 installed on the top surface of the support 1, a top plate 3 installed on the support column 2, a hydraulic cylinder 4 installed on the top plate 3, a movable template 5 connected to the telescopic end of the hydraulic cylinder 4, a fixed template 6 corresponding to the movable template 5 installed on the top surface of the support 1, a groove opened on the top surface of the fixed template 6, a bearing plate 7 installed inside the groove, a distribution air channel 9 and a main air channel 10 opened inside the bearing plate 7, an air hole 11 communicating with the distribution air channel 9 opened on the top surface of the bearing plate 7, and a negative pressure pump 8 installed on the bottom surface of the support 1, the negative pressure end of the negative pressure pump 8 communicating with the main air channel 10.

[0021] Specifically, bracket 1 serves as the foundation support for the entire device, providing an installation platform for other components. Support column 2 is vertically installed on the top surface of bracket 1, supporting top plate 3 and ensuring it is at a suitable height. After the hydraulic cylinder 4 on top plate 3 is activated, its telescopic end drives the movable template 5 to move vertically. Fixed template 6 is fixed to the top surface of bracket 1, opposite to the movable template 5, forming a molding space between them. Bearing plate 7 is installed in the groove on the top surface of fixed template 6 to support the laser card. The distribution air duct 9 and main air duct 10 inside bearing plate 7 are interconnected, and the distribution air duct 9 is connected to the air hole 11 on the top surface. When the negative pressure pump 8 on the bottom surface of bracket 1 operates, it extracts air from the main air duct 10, and the negative pressure is sequentially conducted through the distribution air duct 9 to the air hole 11, thereby adsorbing the laser card onto the bearing plate 7 and ensuring the stability of the card position during molding. When the hydraulic cylinder 4 pushes the movable template 5 downward, the movable template 5 cooperates with the fixed template 6 to mold the fixed laser card. Through the negative pressure adsorption fixing structure, and with the cooperation of the bearing plate 7, distribution air channel 9, main air channel 10, air hole 11 and negative pressure pump 8, the laser card is stably fixed. During the molding process, the card will not move due to pressure, avoiding quality problems such as pattern misalignment and ghosting, and greatly improving product quality. At the same time, the fixing structure makes the card positioning more accurate, reducing the amount of manual adjustment and laying the foundation for automated and large-scale production.

[0022] As a technical optimization of this utility model, a control switch 12 is installed on the bracket 1, and the control switch 12 is electrically connected to the negative pressure pump 8.

[0023] Specifically, the control switch 12 is mounted on the bracket 1 and electrically connected to the negative pressure pump 8. The operator can easily control the start and stop of the negative pressure pump 8 by operating the control switch 12. Before placing the laser card, press the control switch 12 to turn on the negative pressure pump 8, so that the air holes 11 on the carrier plate 7 generate negative pressure, which facilitates the accurate placement and adsorption and fixation of the card. After molding, operate the control switch 12 again to turn off the negative pressure pump 8, eliminate the negative pressure, and then remove the processed laser card.

[0024] As a technical optimization of this utility model, a guide plate 13 is installed on the top wall of the movable template 5, and a guide rod 14 is installed on the top surface of the guide plate 13. The guide rod 14 is slidably connected to the top plate 3.

[0025] Specifically, the movable template 5 is equipped with a guide plate 13 and a guide rod 14 on its top wall, with the guide rod 14 slidably connected to the top plate 3. When the hydraulic cylinder 4 pushes the movable template 5 to move up and down, the guide rod 14 slides along a fixed direction within the sliding structure of the top plate 3, and the guide plate 13 plays an auxiliary guiding and stabilizing role, ensuring that the movable template 5 maintains a stable trajectory during movement and does not deviate or shake.

[0026] As a technical optimization of this utility model, four pillars 2 are provided, and the four pillars 2 are respectively located at the four corners of the top surface of the support 1.

[0027] Specifically, four support pillars 2 are installed at the four corners of the top surface of the support 1, evenly distributed, to jointly support the top plate 3 and components such as the hydraulic cylinder 4 installed on the top plate 3. During the operation of the device, no matter how the molding pressure changes, the four support pillars 2 can evenly bear the weight and pressure, maintaining the overall balance and stability of the device.

[0028] As a technical optimization of this utility model, multiple air holes 11 are provided, and the multiple air holes 11 are distributed in a rectangular array on the support plate 7.

[0029] Specifically, multiple air holes 11 are arranged in a rectangular array on the carrier plate 7. When the negative pressure pump 8 is working, the negative pressure is transmitted to each air hole 11 through the distribution air channel 9, so that the laser card can be subjected to uniform negative pressure adsorption force at all parts of the carrier plate 7, thereby firmly fixing the card to the carrier plate 7.

[0030] As a technical optimization of this utility model, a dustproof film is installed inside the air hole 11, and a cross-shaped cut is made on the dustproof film.

[0031] Specifically, the dustproof membrane installed inside the air hole 11 has a cross-shaped cut. When the device is not working, the dustproof membrane can block dust and other impurities from entering the air hole 11, the distribution air channel 9 and the main air channel 10. When the negative pressure pump 8 works to generate negative pressure, the gas can enter and exit the air hole 11 through the cross-shaped cut on the dustproof membrane without affecting the generation of negative pressure and the adsorption and fixing function of the laser card.

[0032] Working Principle: In this laser card molding device, the support frame 1 serves as the basic support structure, providing a stable placement platform for the entire device. The support column 2 is vertically installed on the top surface of the support frame 1, connecting and supporting the top plate 3. A hydraulic cylinder 4 is installed on the top plate 3, with its telescopic end connected to the movable template 5. When the hydraulic cylinder 4 is activated, it telescopically extends according to control commands, thereby moving the movable template 5 up and down. The fixed template 6 is installed on the top surface of the support frame 1, corresponding to the movable template 5. The bearing plate 7 is installed inside a groove on the top surface of the fixed template 6, forming a bearing area for the laser card. When the hydraulic cylinder 4 pushes the movable template 5 downwards, the distance between the movable template 5 and the fixed template 6 gradually decreases, molding the laser card placed on the bearing plate 7. The bearing plate 7 has a distribution air channel 9 and a main air channel 10 inside, and its top surface has an air hole 11 communicating with the distribution air channel 9. A negative pressure pump 8 is installed on the bottom surface of the support frame 1, with its negative pressure end connected to the main air channel 10. When it is necessary to fix the laser cardstock, the negative pressure pump 8 is activated. The negative pressure pump 8 begins to work, drawing air out of the main air duct 10, creating a negative pressure within the main air duct 10. Since the distribution air duct 9 is connected to the main air duct 10, and the air hole 11 is also connected to the distribution air duct 9, the negative pressure is transmitted to the air hole 11 through the distribution air duct 9. At this time, the laser cardstock placed on the support plate 7 is tightly adsorbed onto the top surface of the support plate 7 under the negative pressure generated at the air hole 11, thus effectively fixing the laser cardstock during the molding process. The control switch 12 installed on the bracket 1 is electrically connected to the negative pressure pump 8. The operator can conveniently turn the negative pressure pump 8 on and off using the control switch 12. Before placing the laser card, the negative pressure pump 8 is turned on by the control switch 12, which creates negative pressure in the air holes 11 on the support plate 7, facilitating the accurate placement and fixation of the laser card. After molding, the negative pressure pump 8 is turned off by the control switch 12, releasing the adsorption of the laser card and making it easy to remove the processed laser card. A guide plate 13 is installed on the top wall of the movable template 5, and a guide rod 14 is installed on the top surface of the guide plate 13. The guide rod 14 is slidably connected to the top plate 3. When the hydraulic cylinder 4 pushes the movable template 5 up and down, the guide rod 14 slides in the corresponding sliding structure on the top plate 3. The guide rod 14 and the guide plate 13 ensure that the movable template 5 maintains a stable movement trajectory during up and down movement, without deviation or shaking, thereby ensuring that the movable template 5 and the fixed template 6 can be accurately aligned during molding, improving the precision and quality of molding. Four support columns 2 are provided, located at the four corners of the top surface of the support 1. This distribution method can evenly bear the weight of the top plate 3 and the hydraulic cylinder 4 installed on the top plate 3, and also provides stable support for the entire device during operation, ensuring that the device will not tilt or shake due to uneven force during the molding operation, and ensuring the smooth progress of the molding operation. Multiple air holes 11 are provided and are distributed in a rectangular array on the support plate 7.This layout ensures that the laser cardstock receives a relatively uniform negative pressure adsorption force across all parts of the carrier plate 7, thus more firmly fixing the laser cardstock and preventing localized instability. Furthermore, a dustproof membrane with cross-shaped slits is installed inside the air vents 11. When the device is not in operation, the dustproof membrane prevents dust and other impurities from entering the air vents 11, the distribution air channels 9, and the main air channel 10, avoiding blockages that could affect the normal operation of the negative pressure pump 8 and the fixation effect on the laser cardstock. When the negative pressure pump 8 generates negative pressure, gas can smoothly enter and exit the air vents 11 through the cross-shaped slits on the dustproof membrane, without affecting the generation of negative pressure or the adsorption and fixation function of the laser cardstock.
