Technical Field

[0001] This invention relates to the technical field of laser film processing equipment, specifically a dual-station laser film hot air circulation curing device. Background Technology

[0002] In the production of laser film, curing is one of the important processing steps. A flow-through process is typically used for curing laser film, which improves production efficiency. However, in this flow-through method, the heating time of the laser film is fixed, and some laser films have specific requirements for the heating time. For laser films requiring long heating times, the flow-through method can easily result in insufficient curing, affecting the quality of later production. Furthermore, uneven heating can easily occur during the curing process, reducing the curing quality and impacting the overall product quality. Summary of the Invention

A double-groove pulley system drives two pulleys to rotate via a belt, causing two rotating rods to rotate. In conjunction with a fixed limiting mechanism, the fixed block engages with the laser film roll, allowing the laser film roll to rotate simultaneously during hot air circulation. This ensures full contact between the laser film surface and the hot air, improving the curing efficiency of the laser film. By rotating the right rotating cylinder before the curing process, the screw rod moves vertically downwards according to the action of the fixed bar and limiting groove, extending into the laser film roll, preventing the laser film roll from falling off and being damaged during the curing process.

A hot air circulation mechanism 5 is installed inside the base 1, with the top of the hot air circulation mechanism 5 extending through the curing box 3 into the interior of the curing box 3. A fixed limiting mechanism is installed above the curing box 3. Structure 6, the fixed limiting mechanism 6 extends through the bottom of the curing box 3 and into the interior of the curing box 3. The hot air circulation mechanism 5 includes a motor 504, a double-groove pulley 505, a circulation cylinder 506, a spiral rod 507, two rotating rods 510 and two pulleys 511. The base 1 has a horizontally opened working chamber 501. The bottom surface of the working chamber 501 has a motor groove 502. The motor 504 is installed inside the motor groove 502. The bottom surface of the motor 504 is fixedly connected to the bottom surface of the motor groove 502. The bottom surface of the motor groove 502 has a heat dissipation hole 503 through the bottom surface of the base 1. The double-groove pulley 505 is fixedly sleeved on the surface of the output rod of the motor 504. The circulation cylinder 506 is vertical. The circulation cylinder 506 is fixedly connected to the inner wall of the maturation tank 3 at its upper and lower ends. A spiral rod 507 is vertically installed inside the circulation cylinder 506. The top of the output rod of the motor 504 extends from bottom to top through the working chamber 501, the maturation tank 3, and the circulation cylinder 506 into the circulation cylinder 506. The top of the output rod of the motor 504 is fixedly connected to the bottom of the spiral rod 507. An air inlet 508 is provided at the bottom of the circulation cylinder 506, and a circulation hole 509 is provided at the top. Two rotating rods 510 are vertically installed left and right inside the working chamber 501, respectively. The bottom of both rotating rods 510 is rotatably connected to the bottom surface of the working chamber 501 through a bearing seat. Two pulleys 511 are fixedly mounted on the surfaces of two rotating rods 510. Both pulleys 511 are connected to the double-groove pulley 505 via belt drive. The tops of the two rotating rods 510 extend through the working chamber 501 and the bottom surface of the curing box 3 into the interior of the curing box 3. By setting up a hot air circulation mechanism 5, the motor 504 rotates, driving the screw rod 507 to rotate. The hot air delivered to the interior of the curing box 3 through the hot air conveying pipe 4 is circulated in the curing box 3 through the air inlet 508 and circulation hole 509 on the surface of the circulation cylinder 506. This allows the hot air to be blown evenly from top to bottom onto the surface of the laser film roll, reducing uneven heat distribution and improving the curing effect of the laser film. The fixed limiting mechanism 6 includes an adjusting frame 601, two receiving plates 602, two fixing blocks 603, two rotating cylinders 604, a threaded rod 605, a fixing strip 607, and two pulleys 608. The adjusting frame 601 has an open bottom surface and is horizontally positioned on the top surface of the curing box 3. The two receiving plates 602 are horizontally fixed on the top surfaces of the two rotating rods 604. The two fixing blocks 603 are vertically fixed on the top surfaces of the two receiving plates 602. The receiving plates 602 are hollowed out. The fixing blocks 603 are cuboids, and their top surfaces fit the inner wall of the laser film roll. The two rotating cylinders 604 are vertically positioned on the left and right sides inside the adjusting frame 601. The bottom ends of the two rotating cylinders 604 are rotatably connected to the top surface of the curing box 3 through bearing seats 604. The top of the right rotating cylinder 604 penetrates the adjusting frame 601. 01 extends above the adjustment frame 601. Two pulleys 608 are fixedly sleeved on the surfaces of two rotating cylinders 604 respectively. The two pulleys 608 are connected by a belt. A threaded rod 605 is vertically installed inside the rotating cylinder 604. The bottom end of the threaded rod 605 passes through the rotating cylinder 604 and the curing box 3 and extends into the curing box 3. The surface of the threaded rod 605 is threadedly connected to the inner wall of the rotating cylinder 604. A limiting groove 606 is vertically opened on the side of the threaded rod 605. A fixing strip 607 is vertically slidably installed inside the limiting groove 606. The side of the fixing strip 607 is fixedly connected to the inner wall of the curing box 3. By rotating the right rotating cylinder 604 before the curing process, the threaded rod 605 moves vertically downward according to the action of the fixing strip 607 and the limiting groove 606, extending into the laser film roll, so that the laser film roll will not fall off and be damaged during the curing process.

[0016] In use, a hot air circulation mechanism 5 is set up. The motor 504 rotates, driving the screw 507 to rotate. The hot air, delivered through the hot air delivery pipe 4 to the curing box 3, circulates within the curing box 3 via the air inlet 508 and circulation holes 509 on the surface of the circulation cylinder 506. This ensures the hot air is evenly blown from top to bottom onto the surface of the laser film roll, reducing uneven heat distribution and improving the curing effect of the laser film. A double-groove pulley 505 drives two pulleys 511 to rotate via belt one, causing the two pulleys to rotate. The rotating rod 510 rotates, cooperating with the fixed limiting mechanism 6, and interlocks with the laser film roll through the fixing block 603, so that the laser film roll can rotate simultaneously during hot air circulation, allowing the surface of the laser film to fully contact the hot air and improve the curing efficiency of the laser film. By rotating the right rotating cylinder 604 before the curing process, the threaded rod 605 moves vertically downward according to the action of the fixing strip 607 and the limiting groove 606, extending into the laser film roll, so that the laser film roll will not fall off and be damaged during the curing process.
