The shape of the rack 309 is the same as that of the first slide groove 308.

[0034] During operation, by pushing the movable plate 306 to move downward inside the first movable groove 302, the movable plate 306 simultaneously drives the limiting plate 305 to compress the first spring 304 downward, and the movable plate 306 drives the clamping block 307 to clamp the two ends of the plastic plate downward, thereby preventing the problem of the plastic plate warping up on both sides during rolling, and at the same time preventing the plastic plate from moving during the rolling process, thereby improving the rolling quality of the plastic plate.

[0035] As an embodiment of the present invention, Figure 3 , Figure 4 and Figure 5As shown, the rolling mechanism 4 includes a second movable groove 401, a rotating shaft 402, a gear 403, a motor 404, a third movable groove 405, a stabilizing plate 406, a slide plate 407, a push plate 408 and a pressing wheel 409.

[0036] During operation, the motor 404 is energized through the equipment control. After the motor 404 is energized, it drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives the gear 403 to rotate. Because the gear 403 is meshed with the rack 309, the gear 403 drives the rotating shaft 402 to slide inside the first slide groove 308. Because the middle part of the first slide groove 308 is 5 cm lower than the two ends, the rotating shaft 402 pushes the movable plate 306 downward, and the rotating shaft 402 drives the motor 404 to move, and the motor 404 drives the stable plate 406 to move.

At this time, under the action of the rotating shaft 402, the motor 404 moves downward, so that the stable plate 406 slides upward in the third movable groove 405, and at the same time, the push plate 408 drives the pressing wheel 409 downward to roll the plastic plate inside the pressing groove 5, thereby improving the stability of the equipment, thereby ensuring the automation effect of the equipment, and effectively completing the rolling process of the plastic plate.

[0037] As an embodiment of the present invention, Figure 6 and Figure 7As shown, the blocking mechanism 6 includes a second slide groove 601, a slide rod 602, a transmission rod 603, an inclined block 604, a fixed plate 605, a second opening 606, a third slide groove 607, a baffle 608, a second spring 609 and a fixed block 610. The second movable groove 401 is provided with a second slide groove 601 through the inside, and the slide rod 602 is slidably connected to the inside of the second slide groove 601. The transmission rod 603 is fixedly welded to the outside of the slide rod 602. The middle part of the lower end of the transmission rod 603 is fixedly connected to the inclined block 604. The inclined angle of the inclined block 604 is 45°. The outside of the workbench 1 is fixedly connected by bolts. A fixed plate 605 is connected, and a second opening 606 is provided at the lower end of the outer wall of the fixed plate 605. The size of the second opening 606 is adapted to the size of the pressing groove 5. A third slide groove 607 is provided inside the second opening 606. The bottom of the third slide groove 607 is arranged to be adapted to the inclined structure of the inclined block 604. A baffle 608 is slidably connected inside the third slide groove 607. The inner outer wall of the transmission rod 603 is fixedly connected to one end of the second spring 609. The other end of the second spring 609 is fixedly connected to a fixed block 610. The fixed block 610 is welded to the outer wall of the workbench 1.

[0038] During operation, under the action of the slide plate 407, the slide bar 602 is pushed to move outward inside the second slide groove 601, and the slide bar 602 drives the transmission rod 603 to move outward. The transmission rod 603 stretches the second spring 609 outward, and the transmission rod 603 drives the inclined block 604 to move outward. The inclined block 604 cannot support the baffle plate 608. The baffle plate 608 moves downward inside the third slide groove 607 under the action of gravity, which can limit the movement of the plastic sheet and enable the plastic sheet to continue to move after rolling processing, thereby ensuring the continuity of the plastic sheet processing and improving the processing efficiency of the plastic sheet.

[0039] Working principle: In the initial state, under the action of the extension force of the first spring 304, the movable plate 306 is at the highest position inside the first movable groove 302, and the rotating shaft 402 is at the highest position at both ends of the first slide groove 308, so that the motor 404 is at the highest position, so that the push plate 408 drives the pressure wheel 409 to be at the highest position, and at the same time, under the action of the contraction force of the second spring 609, the transmission rod 603 drives the inclined block 604 to abut against the bottom of the baffle 608, and the baffle 608 is at the highest position.

[0040] Start the device, and under the action of external equipment, the plastic sheet is continuously transmitted to the inside of the workbench 1. The plastic sheet stops inside the workbench 1 under the action of the baffle 608. At this time, under the control of the device, the motor 404 is powered on and started. After the motor 404 is powered on, it drives the rotating shaft 402 to rotate, and the rotating shaft 402 drives the gear 403 to rotate. Because the gear 403 and the rack 309 are meshed with each other, the gear 403 drives the rotating shaft 402 to slide inside the first slide groove 308. Because the middle part of the first slide groove 308 is 5 cm lower than the two ends, the rotating shaft 402 pushes the movable plate 306 downward, and the movable plate 306 moves downward inside the first movable groove 302. The movable plate 306 also drives the limit plate 305 to compress the first spring 304 downward, and the movable plate 306 drives the clamping block 307 to clamp the two ends of the plastic sheet downward.

[0041] At the same time, the shaft 402 drives the motor 404 to move, the motor 404 drives the stabilizing plate 406 to move, and the stabilizing plate 406 drives the slide plate 407 to slide inside the second movable groove 401, so that the motor 404 can move vertically and stably inside the workbench 1. At this time, under the action of the shaft 402, the motor 404 moves downward, so that the stabilizing plate 406 slides upward in the third movable groove 405, and at the same time, the push plate 408 drives the pressing wheel 409 downward to roll the plastic plate inside the pressing groove 5. After the rolling process is completed, the slide bar 602 is pushed in the second slide groove 601 under the action of the slide plate 407. The inside moves outward, the slide rod 602 drives the transmission rod 603 to move outward, the transmission rod 603 stretches the second spring 609 outward, the transmission rod 603 drives the inclined block 604 to move outward, the inclined block 604 cannot support the baffle 608, the baffle 608 moves downward inside the third slide groove 607 under the action of gravity, and the plastic sheet moves outward through the second opening 606 under the action of subsequent plastic sheets, thereby completing the processing operation, and the motor 404 drives the rotating shaft 402 to rotate in the opposite direction under the control of the equipment, and the rotating shaft 402 drives the gear 403 to rotate in the opposite direction, thereby restoring the motor 404 to its initial position.

[0042] To sum up, the advantages of the present invention are to prevent the problem of the two sides of the plastic plate being lifted up during rolling, and at the same time prevent the plastic plate from moving during the rolling process, thereby improving the quality of the plastic plate rolling, improving the stability of the equipment, and thus ensuring the automation effect of the equipment, being able to limit the movement of the plastic plate, and enabling the plastic plate to continue to move after the rolling process, thereby ensuring the continuity of the plastic plate processing and improving the processing efficiency of the plastic plate.
