[0004] In the above scheme, the rubber block is used to apply pressure to the plastic plate to fix the plastic plate on the support table, which still has the following disadvantages: when the plastic plate is fixed on the support table, the rubber block and the plastic plate have a sliding friction with a large friction force, and the large friction force may reduce the convenience of pushing the plastic plate to move. Utility Model Content

[0005] The utility model aims to provide an improved plastic plate cutting device to solve the problem that the rubber block and the plastic plate have a relatively large sliding friction, and the relatively large friction may reduce the convenience of pushing the plastic plate to move.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: an improved plastic plate cutting equipment, including a processing table, a lifting plate is slidably arranged above the processing table, a driving motor is fixed to the bottom surface of the lifting plate, a cutting blade is detachably arranged on one end of the output shaft of the driving motor, two sliding holes are arranged on the top surface of the lifting plate, a lifting rod is slidably inserted inside the sliding hole, a connecting plate is fixed to the bottom end of the lifting rod, a spring is surrounded by the surface of the lifting rod, one end of the spring is fixed to the top surface of the connecting plate, and the other end of the spring is fixed to the bottom surface of the lifting plate, a rotating column is fixed to the bottom surface of the connecting plate, a roller is rotatably arranged below the connecting plate, a rotating groove is arranged on the top surface of the roller, a bearing is fixed inside the rotating groove, and the surface of the rotating column is fixed to the inner wall surface of the inner ring of the bearing.

[0011] Preferably, a receiving opening is provided on the top surface of the processing table.

[0012] Compared with the prior art, an improved plastic plate cutting device using the above technical solution has the following beneficial effects:

[0013] 1. Before cutting the plastic plate, the staff will first rotate the adjusting nut on the threaded column counterclockwise to adjust the height of the lifting plate above the processing table. Then the staff will place the plastic plate on the top surface of the processing table, and then rotate the adjusting nut clockwise to drive the lifting plate to move down, and then drive the roller to press on the top surface of the plastic plate. As the lifting plate continues to descend, the spring will be slowly compressed, and the compressed spring will exert a downward force on the connecting plate, and then the roller can be continuously used to exert a downward force on the plastic plate to press and fix the plastic plate on the top surface of the processing table. Since the plastic plate is in contact with the roller, the friction force when the staff pushes the plastic plate for cutting is reduced, which increases the convenience of cutting the plastic plate;

[0014] Second, the downward moving lifting plate will drive the cutting disc to descend synchronously. The excessively descending cutting disc will enter the interior of the accommodating port to protect the cutting disc from damage. As the cutting disc is used for a longer time, it will inevitably be damaged. At this time, the staff will first unscrew the threaded ring out of the surface of the output shaft of the drive motor, and then remove the cutting disc and replace it with a new one. When installing the new cutting disc, the limit groove and the limit plate can be connected together, and finally the threaded ring is rotated and squeezed on one side of the cutting disc, which increases the convenience of the staff when replacing the cutting disc;

[0015] 3. The scraps cut by the cutting disc will fall from the top surface of the processing table and enter the interior of the storage box under the push of the subsequent plastic plate. When the interior of the storage box is filled with scraps, the staff will pull the storage box out from between the two fixed plates to recycle the cut scraps, reducing the loss during processing.

The through holes 13 are slidably inserted with the threaded columns 12. Two adjusting nuts 14 are threadedly connected to the threaded columns 12, and the lower adjusting nuts 14 support the lifting plate 2 upward.

[0023] During use, before cutting the plastic plate, the staff will first rotate the adjusting nut 14 on the threaded column 12 counterclockwise to adjust the height of the lifting plate 2 above the processing table 1, and then the staff will place the plastic plate on the top surface of the processing table 1, and then rotate the adjusting nut 14 clockwise to drive the lifting plate 2 to move down, and then drive the roller 10 to press on the top surface of the plastic plate. As the lifting plate 2 continues to descend, the spring 7 will be slowly compressed, and the compressed spring 7 will apply a downward force to the connecting plate 8, and then the roller 10 can be continuously used to apply a downward force to the plastic plate to press and fix the plastic plate on the top surface of the processing table 1.

As the cutting disc 4 is used for a longer time, it will inevitably be damaged. At this time, the staff will first unscrew the threaded ring 18 out of the surface of the output shaft of the drive motor 3, and then remove the cutting disc 4 and replace it with a new one. When installing the new cutting disc 4, the limit groove 17 and the limit plate 16 can be connected together, and finally the threaded ring 18 is rotated and squeezed on one side of the cutting disc 4, which increases the convenience of the staff when replacing the cutting disc 4.
