[0003] However, when dust or water adheres to the plastic sheet or mold, the high-frequency machine will spark, causing damage to the plastic sheet or mold, thus affecting production;

[0004] And if the voltage is unstable, it may cause unstable discharge, which may lead to sparking. Therefore, workers will observe the voltage. When the voltage is unstable, they will stabilize the voltage by twisting the adjustment knob to avoid voltage instability. Utility Model Content

The ejected gas will blow away the dust attached to the upper mold and the lower mold, thereby preventing the upper mold and the lower mold from igniting due to the attached dust. At the same time, since the sponge is in contact with the two plastic sheets, the sponge absorbs the water that may be attached to the plastic sheets, and the sponge scrapes away the dust on the plastic plate, thereby cleaning the plastic plate. At the same time, when the plastic plate is cleaned by the sponge, it can avoid the plastic sheet from swinging when directly blown with air, thereby preventing wrinkles and position shifts, and it can also avoid the inability to quickly clean up the water with air.

[0014] When the clamping rod moves on the plastic sheet, the threads of the clamping rod will push the middle of the plastic sheet to the left and right sides, thereby flattening the wrinkles caused by manual placement.

[0015] When the current detector detects that the current voltage increases or decreases, the stepper motor drives the knob to rotate, thereby controlling the current and voltage, thereby replacing the worker's adjustment and reducing the worker's operating burden. At the same time, the adjustment response can be made faster to avoid sparking. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The material clamping assembly includes an electric push rod 121, a clamping plate 122 and a clamping rod 123; two electric push rods 121 are fixedly connected to the upper and lower sides of the high-frequency machine 1; each telescopic part of each electric push rod 121 is fixedly connected to a clamping plate 122; each rear part of each jet plate 5 is fixedly connected to a clamping rod 123; each clamping rod 123 is provided with a thread 123a; the threads 123a on the left and right sides are in opposite directions.

[0027] It also includes a DD motor 116; each fixed block 115 is fixedly connected to a DD motor 116; the rotating part of the DD motor 116 is fixedly connected to the corresponding jet plate 5; nine jet holes 5c are opened on the opposite sides of the two jet plates 5; the jet holes 5c are connected to the cavity.

[0028] The air jet hole 2 5 c is inclined forward so that the blown dust and water are kept away from the sponge 6 opposite thereto.

[0029] It also includes a stepper motor 7; two stepper motors 7 are installed at the lower part of the high-frequency machine 1; the output shaft of the stepper motor 7 is fixedly connected to the knob for controlling the voltage of the high-frequency machine 1, and the stepper motor 7 is connected to an external power supply.

[0030] The specific working steps are:

[0031] The air inlet 5a is connected to an external air supply device;

[0032] During operation, the two plastic sheets are first placed on the lower sponge 6 and the lower clamping plate 122, and then the electric guide rail 111 drives the upper moving block 112 to drive the fixed block 113, the electric push rod 114, the fixed block 115, the jet plate 5 and the sponge 6 connected thereto to descend, thereby clamping the two plastic sheets. At the same time, the upper electric push rod 121 drives the clamping plate 122 to descend, clamping the front ends of the two plastic sheets, and then the external air supply device will supply gas to the air inlet 5a, so that the gas enters the cavity, and then is ejected from the jet hole 5b. At this time, the ejected gas will blow away the dust attached to the upper mold 3 and the lower mold 4. Dust is removed, thereby preventing the upper mold 3 and the lower mold 4 from sparking due to dust adhesion. At the same time, since the sponge 6 is in contact with the two plastic sheets, the sponge 6 absorbs the water that may be attached to the plastic sheets, and then the electric push rod 114 drives the jet plate 5 and the sponge 6 to move backward through the fixed block 2 115, so that the sponge 6 scrapes away the dust on the plastic sheet, thereby cleaning the plastic sheet. At the same time, when the sponge 6 cleans the plastic sheet, it can avoid the plastic sheet swinging when directly blowing with air, thereby preventing wrinkles and position deviation, and it can also avoid the inability to quickly clean the water with air blowing;

[0033] When the jet plate 5 and the sponge 6 move backward, the clamping rod 123 will be in close contact with the plastic sheet. Therefore, when the clamping rod 123 moves on the plastic sheet, the thread 123a of the clamping rod 123 will push the middle part of the plastic sheet to move to the left and right sides, thereby flattening the wrinkles caused by manual placement. When the jet plate 5 and the sponge 6 move and no longer contact the plastic sheet, the clamping rod 123 will continue to clamp the plastic sheet. At this time, the electric guide rail 111 drives all the moving blocks 112 to descend, so that the moving blocks 112 drive the jet plate 5 and the clamping rod 123 next to the plastic sheet to descend. At the same time, the electric push rod 121 drives the clamping plate 122 to descend, so that the plastic sheet contacts the lower mold 4, and then the electric telescopic rod 2 drives the upper mold 3 to descend to clamp the plastic plate, thereby performing heat sealing.

[0034] At the same time, the electric guide rail 111 drives the moving block 112 below to drive the lower jet plate 5 and the lower clamping rod 123 to descend, and then the DD motor 116 drives the jet plate 5 to rotate, so that the two jet plates 5 are in a less than sign when viewed from right to left, and then the external air supply device delivers gas again, so that the gas will enter the cavity again. Because the sponge 6 was previously in close contact with the plastic plate, the second jet hole 5c was blocked, resulting in the gas being unable to be ejected from the second jet hole 5c. At this time, the second jet hole 5c is no longer blocked by the plastic plate, so that the gas is ejected from the second jet hole 5c. At this time, the ejected gas will clean the sponge 6, blow away the dust attached to the sponge 6 during cleaning, and at the same time dry the water attached to the sponge 6, so as to avoid excessive accumulation, resulting in incomplete cleaning and ignition.

[0035] When the heat sealing work is completed, the upper electric push rod 2 121 will drive the clamping plate 122 to rise back to the original position, and the electric telescopic rod 2 will drive the upper mold 3 to rise back to the original position, and then the plastic sheet will be taken out, and then the electric guide rail 111, the moving block 112 and the electric push rod 1 114 will be controlled to drive the jet plate 5 and the sponge 6 back to the original position for the next work;

[0036] A current detector is installed in the high-frequency machine 1 to detect the voltage in the high-frequency machine 1. When the current detector detects that the current voltage becomes larger or smaller, the stepper motor 7 drives the knob to rotate to control the current voltage, thereby replacing the worker's adjustment and reducing the worker's operating burden. At the same time, the adjustment response can be made faster to avoid sparking.
