Description

Technical Field

[0001] This utility model relates to the field of plastic blister tray technology, specifically a heating device for plastic blister tray substrate. Background Technology

[0002] Blister trays, also known as plastic inner trays, are made by forming a plastic sheet into a specific groove using a blister forming process. Products are placed in the groove to protect and enhance their appearance. There are also transport-type trays. The most common use of trays is for convenience.

[0003] After the blister tray roll is unwound and before blister forming, the roll is transferred to the bottom of the heating seat. The heating wire on the heating seat heats and softens the roll, making it easier to blister form. However, there is a certain distance between the heating seat and the roll, which is easily affected by airflow, resulting in uneven heating of the roll and affecting the subsequent blister forming effect. Therefore, we propose a heating device for plastic blister tray substrate to solve this defect of the existing technology. Utility Model Content

[0026] 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.

[0027] Please see Figures 1 to 4The heating device for the plastic blister tray substrate in this embodiment includes components such as a mounting frame 1, a lower heating seat 2, a pushing component 3, an upper heating seat 4, heating wires 6, and heat-conducting rollers 12. The lower heating seat 2 is fixedly mounted on the bottom wall of the mounting frame 1, and the upper heating seat 4 is located above the lower heating seat 2. The pushing component 3, fixed on the upper surface of the mounting frame 1, is used to push the upper heating seat 4 to move. Multiple heating wires 6 are fixedly arranged at equal intervals in both the lower heating seat 2 and the upper heating seat 4. Multiple air holes 5 are opened on the opposite surfaces of the lower heating seat 2 and the upper heating seat 4. Multiple heat-conducting rollers 12 are rotated and attached to the opposite surfaces of the lower heating seat 2 and the upper heating seat 4. The mounting frame 1 is also provided with an air supply component for supplying air to the lower heating seat 2 and the upper heating seat 4.

[0028] The front and rear surfaces of the lower heating seat 2 and the upper heating seat 4 are provided with multiple rotating seats through which the heat-conducting roller 12 passes and rotates, and the rotating seats ensure the stability of the rotation of the heat-conducting roller 12.

[0029] Mounting frame 1 is the supporting structure of the entire device. It is made of high-strength steel and has good stability and load-bearing capacity. The pushing component 3 is a hydraulic push rod, which can be replaced by other push structures. The push rod of the hydraulic push rod is connected and fixed to the heating seat 4, which can realize the up and down movement of the heating seat 4. The heating wire 6 is made of high-quality alloy material and can generate uniform heat to heat the roll material.

[0030] The pusher 3 pushes the upper heating seat 4 to move, so as to adjust the distance between the upper heating seat 4 and the lower heating seat 2 to accommodate roll materials of different thicknesses. The air holes 5 are evenly distributed to ensure that the hot air can be discharged evenly and to heat the roll material comprehensively.

[0031] Both the lower heating seat 2 and the upper heating seat 4 have arc-shaped grooves on their surfaces for the heat-conducting roller 12 to be inserted, ensuring the stability of the heat-conducting roller 12 when it rotates. The heat-conducting roller 12 is made of a metal material with high thermal conductivity, such as aluminum alloy or copper alloy, which can quickly transfer heat to the roll material. At the same time, its surface is smooth, reducing frictional damage to the roll material.

[0032] The air supply assembly includes a booster fan 7 fixed on the upper surface of the mounting bracket 1. The exhaust port of the booster fan 7 is connected to the exhaust pipe 9. The other end of the exhaust pipe 9 is connected to the lower heating seat 2 and the upper heating seat 4 through the connecting hose 8. When the booster fan 7 is working, it compresses air into the exhaust pipe 9, and then delivers it to the lower heating seat 2 and the upper heating seat 4 through the hose 8. Finally, it is discharged from the air hole 5 and mixes with the heat generated by the heating wire 6 to form a hot airflow to heat the roll material.

[0033] A pair of drive motors 11, symmetrically distributed vertically, are mounted and fixed on the right rear side of the mounting frame 1. The output end of the drive motor 11 is connected and fixed to a guide roller 10. The guide roller 10 is rotatably connected to the front side of the mounting frame 1. The guide roller 10 is used to guide the transmission direction of the roll material to ensure that the roll material enters the heating area smoothly.

[0034] A sliding limiting plate 15 is sleeved between the front and rear outer sides of the heat-conducting roller 12 located on the upper heating seat 4. Loading frames 13 are fixed on both the front and rear surfaces of the upper heating seat 4. An electric push rod 14 is installed and fixed on the surface of the loading frame 13. The push rod of the electric push rod 14 is connected and fixed to the limiting plate 15. By the extension and retraction of the electric push rod 14, the limiting plate 15 is pushed to move, thereby limiting the side of the conveyed roll material and preventing the roll material from shifting during the heating process, thus ensuring the accuracy of the heating position.

[0035] The limiting plate 15 is provided with sliding rods 16 on both the left and right sides. The sliding rods 16 are slidably connected to the upper heating seat 4 to ensure the stability of the movement of the limiting plate 15.

[0036] The structural design principle and usage steps are as follows: Place the heating device for the plastic blister tray substrate on a flat work surface, ensuring the stability of mounting frame 1.

[0037] After the plastic blister tray roll is unwound, the roll is guided to be transferred between the lower heating seat 2 and the upper heating seat 4 at the upper end of the mounting frame 1. The drive motor 11 is started, which drives the guide roller 10 to rotate, so that the roll located between the guide rollers 10 is smoothly transferred to the heating area.

[0038] The hydraulic pusher 3 is activated, which pushes the upper heating seat 4 downward, so that the heat-conducting rollers 12 on the lower heating seat 2 and the upper heating seat 4 clamp the roll material. At the same time, the booster fan 7 is activated, which forces air into the exhaust pipe 9 and delivers it to the lower heating seat 2 and the upper heating seat 4 through the hose 8, and then discharges it from the air hole 5. The heating wire 6 is energized and heats up, which heats the discharged air and forms a hot airflow that evenly heats both sides of the roll material. The heat-conducting rollers 12 rotate continuously during the roll material transfer process, transferring heat to the roll material to achieve uniform heating and softening of the roll material.

[0039] Adjust the extension length of the electric push rod 14 according to the width of the roll material, and push the limiting plate 15 to move so that the limiting plate 15 is close to both sides of the roll material to limit the roll material from the side, prevent it from shifting during the heating process, and ensure the accuracy of the heating position.

[0040] It is equipped with a PLC-based automated control system to achieve centralized control of the heating device for the plastic blister tray substrate.

[0041] Beneficial effects: Multiple air holes 5 are provided on the opposite surfaces of the upper heating seat 4 and the lower heating seat 2, and the pressurized airflow provided by the air supply component, combined with the heating effect of the heating wire 6, achieve uniform discharge of hot airflow, and uniformly heat both sides of the roll material. At the same time, the close-fitting and rotating design of the heat-conducting roller 12 not only assists in the transmission of the roll material, but also directly transfers heat to the roll material, further improving the uniformity and efficiency of heating. This solves the problem of uneven heating of the roll material caused by the influence of airflow in traditional heating devices, and ensures the quality of subsequent thermoforming.

[0042] The drive motor 11 drives the guide roller 10 to rotate, providing stable transmission power for the roll material. The electric push rod 14 pushes the limit plate 15 to move, limiting the roll material from the side, effectively preventing the roll material from shifting during transmission and heating, ensuring the accuracy of the heating position, avoiding uneven heating and forming defects caused by roll material offset, and improving the yield rate of production.

[0043] The pusher 3 can adjust the distance between the upper heating seat 4 and the lower heating seat 2 according to the thickness of the roll material, adapting to roll materials of different specifications. The cooperation between the electric push rod 14 and the limiting plate 15 can flexibly adjust the limiting width to meet the heating requirements of roll materials of different widths.

[0044] In summary, the plastic blister tray substrate heating device in this embodiment has a reasonable structure and complete functions. It can effectively improve the heating uniformity and quality of the roll material, enhance the stability of the roll material transmission, and has good adaptability and flexibility. It can significantly improve the efficiency and quality of plastic blister tray production and is a highly practical device with broad application prospects.
