[0017] Figure 3 This is a schematic diagram of the blade lifting mechanism and the blade clamping mechanism. Detailed Implementation

[0018] like Figure 1 , 2 As shown in Figure 3, a dust-free cutting machine includes a frame 1, a follower frame 2, a roller mechanism 3, a front pressure foot 4, a rear pressure foot 5, a blade lifting mechanism 6, and a blade clamping mechanism 7. The follower frame 2 is slidably mounted on the frame 1. The roller mechanism 3 is mounted on the surface of the follower frame 2. The follower frame 2 is mounted on guide rails via mounting brackets and has the blade lifting mechanism 6 and blade clamping mechanism 7 mounted on it. A synchronous drive mechanism is mounted on the follower frame 2 to drive the blade lifting mechanism 6 and blade clamping mechanism 7 to move. A hot air duct of an external hot air system is fixedly mounted on the front shaft side of the blade lifting mechanism 6 and blade clamping mechanism 7. The follower frame 2 is also equipped with a front pressure foot 4 and a rear pressure foot 5 respectively located in front of and behind the blade lifting mechanism 6.

[0019] The synchronous drive mechanism consists of a ball screw 9, a sprocket mechanism 10, and a geared motor 11. The blade lifting mechanism 6 and the blade clamping device 7 are respectively installed on the guide rail and the ball screw 9. The two sets of ball screws 9 are connected through the sprocket mechanism 10 and connected to the geared motor 11.

[0020] The driving blade lifting mechanism 6 is composed of a mounting frame, a lifting cylinder 62 and a blade 63, and the blade 63 is fixed to the extension of the lifting cylinder 62.

[0021] The front pressing foot 4 and the rear pressing foot 5 are lowered by the pressing foot cylinder on the mounting frame and are pressed on the front and rear of the product to be cut off when cutting; the hot air system starts the heating and blowing device, the product surface is heated by hot air, the speed reducer 11 starts to run, the blade lifting mechanism 6 and the blade clamping device 7 on the upper and lower sliding plates are moved by the rotation of the upper and lower ball screws 9, before this, the blade is first clamped, the lifting cylinder 62 of the blade lifting mechanism 6 drives the blade 63 to descend, at this time, the upper blade clamping device 7 of the lower sliding plate is clamped by the horizontal cylinder 71 to drive the blade 63, so as to achieve the function of fixing the blade; then the whole sliding plate moves, gradually heats and cuts off the product, after cutting, the blade rises and the pressing foot rises.

[0022] In addition, the front and rear pressing feet make the product and the follow-up frame 2 more stable and follow, and the follow-up cylinder 8 is installed in the frame 1, the extension of the follow-up cylinder 8 is fixedly connected with the follow-up frame 2 through a connecting plate.

[0023] The working principle is that when the product reaches the length to be cut off, the front and rear pressing foot cylinders work to press the product, the product can drive the follow-up frame to run along the frame rail, so that when cutting is completed, the blade rises and the pressing foot rises; the follow-up cylinder can be used to pull the follow-up frame back to the original position, and then the next cutting instruction is waited.

[0024] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, any modification, equivalent replacement or improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
