[0002] During the processing and production of plastic - molded parts, it is necessary to trim the edges and corners of the plastic - molded parts so that the edges and corners of the plastic - molded parts become smoother and rounder. Most of the products in the processing are box - type plastic - molded parts; currently, the R - angle processing of plastic - sheet parts in the household industry is carried out on CNC equipment, and the following technical disadvantages and problems occur during the processing: 1. After the existing electronic saw cuts, it cannot directly process the arc of the four right - angles of the sheet. During processing, the utilization rate of the sheet is relatively low, the cost increases, and the processing efficiency is relatively slow; 2. When processing on a straight - line edge - grinding machine for four - side grinding, the right - angles cannot be processed. At the same time, different equipment attempts cannot be completed; and for the straight - line sanding process, the next process requires manual cooperation with sandpaper grinding. The R - angle sizes of the four right - angle edges are different and not round, which does not meet the process requirements; for plastic - molding processing, a backing plate needs to be added, resulting in low production capacity and relatively slow efficiency; when processing the R - angle on a plastic - molding equipment, it is easy to not meet the processing requirements, resulting in wrinkled corners of the film skin, generating a large number of defective products, and secondary repair is required, increasing the cost; 3.

After processing, the rotary cutting mechanism is offset by the avoidance mechanism, so as to achieve the protection effect, prevent the tool from being damaged, have a long service life, reduce the replacement time and improve the production efficiency.

[0028] In the present utility model, the up-and-down operation mechanism includes an up-and-down air cylinder 11 vertically arranged on the box body 20. The top of the up-and-down air cylinder 11 is connected with a connecting steel plate 17. The connecting steel plate 17 is connected with the rotary cutting mechanism. The rotary cutting mechanism is pushed by the up-and-down air cylinder 11 to process the sheet.

[0029] In the present utility model, cylinder bases 13 are symmetrically arranged at the bottom of the box body 20. A connecting shaft 22 penetrates through the symmetric cylinder bases 13. The up-and-down air cylinder 11 is connected with a cylinder connecting plate 23. A connecting shaft 22 is arranged between the cylinder connecting plate 23 and the cylinder base 13. Through the connecting shaft 22 and the cylinder connecting plate 23, the up-and-down air cylinder 11 is rotatable.

[0030] In the present utility model, the avoidance mechanism includes a left-and-right air cylinder 10 arranged horizontally.

[0031] In the present utility model, a left limit plate 16 of the up-and-down air cylinder 11 is arranged on the side wall of the box body 20. The left limit plate 16 limits the up-and-down air cylinder 11 pushed by the left-and-right air cylinder 10. The offset of the up-and-down air cylinder 11 is limited by the left limit plate 16 to ensure that the up-and-down air cylinder 11 offsets by 10 degrees.

[0032] In the present utility model, the rotary cutting mechanism includes a rotary cutting motor 3 and a rotary cutting tool 9. The rotary cutting motor 3 is fixed on the connecting steel plate 17. The rotor shaft of the rotary cutting motor 3 extends out of the box body 20 and is fixedly connected with the rotary cutting tool 9 by a reverse-thread screw. The rotary cutting tool 9 is located on the operation table 1, which is convenient for processing the sheet.

[0033] In the present utility model, a dust suction port 4 is fixedly connected to the side wall of the box body 20 by screws. The dust suction port 4 corresponds to the rotor shaft of the rotary cutting motor 3. The dust suction port 4 is connected with a dust suction mechanism, which can extract the dust generated during the processing of the sheet.

[0034] In the present utility model, a tool safety shield 19 is welded to the box body 20. The tool safety shield 19 is used to protect the rotary cutter 9. The tool safety shield 19 covers the tool, protecting the tool and the safety of the operator at the same time.

[0035] In the present utility model, a front stop 2 and a left stop 18 are provided on the operation table surface 1. The connection part of the front stop 2 and the left stop 18 corresponds to the position of the rotary cutter 9, which can position the plate material and can adapt to the processing of various large, medium and small plate materials, with a wide processing range.

[0036] In the present utility model, an operation electrical control system is further included. This system includes a rotary cutting trigger switch 21, a solenoid valve 5, a frequency converter 6, a start button 7, a pressure gauge 8, a pressure regulating valve 12, and a power switch 15. The rotary cutting trigger switch 21 is provided on the front stop 2. The placed plate member pushes the rotary cutting trigger switch 21, and the switch gives a start signal for the up and down cylinders 11 to act. The solenoid valve 5 is provided on the side wall of the box body 20 near the up and down cylinders 11 and the left and right cylinders 10. The solenoid valve 5 is responsible for switching the air source for the up and down movements of the up and down cylinders 11 and the left and right movements of the left and right cylinders 10. The frequency converter 6, the start button 7, the pressure gauge 8, and the power switch 15 are provided on the side of the box body 20 opposite to the solenoid valve 5.

The pressure regulating valve 12 is used to adjust the air pressure of the air source of the up and down cylinders 11 and the left and right cylinders 10.

[0037] The implementation principle of a plastic sheet R-shaped chamfering device of the present utility model is as follows:

[0038] Turn on the power switch 15 to supply power to the system; observe that the pressure gauge 8 reaches the pressure value. Place a backing plate on the operation table surface 1, and then place the processing plate member on the operation table surface 1, press it against the left stop 18 and push it forward to the front stop 2, trigger the rotary cutting trigger switch 21 to make the up and down cylinders 11 move downward. The rotary cutting motor 3 drives the rotary cutter 9 to rotate and cut the right angle of the plate member to an R2.5 radian. After removing the plate member, the rotary cutting trigger switch 21 loses the signal and the up and down cylinders 11 rise. At the same time, the output rod of the left and right cylinders 10 is pushed out, thereby pushing the up and down cylinders 11 to make the up and down cylinders 11 deflect 10 degrees to the left to avoid the backing plate and prevent damage;

[0039] During the rotary cutting process, the tool safety shield 19 protects the rotary cutter 9, and the dust generated by the rotary cutting is discharged through the dust suction port 4.

[0040] The above exemplary description of the present utility model is made in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
