Figure 2 , 3 The release shaft 102 is connected and driven by a release shaft motor 15 installed on the equipment housing 17. A cam mechanism is installed on the release shaft 102 for movably connecting the lifting plate 105. The lifting plate 105 performs periodic lifting and lowering motions driven by the release shaft 102 and the cam mechanism.

[0044] Further, such as Figures 3 to 6 As shown, the cam mechanism includes a bearing fixing seat 101, a cam follower bearing 104 and a cam 1. The cam follower bearing 104 is supported on the bearing fixing seat 101, and the bearing fixing seat 101 is fixed on the lifting plate 105. The cam 1 connected and driven by the release shaft 102 contacts the outer periphery of the cam follower bearing 104, and the cam follower bearing 104 is relatively fixed with the bearing fixing seat 101. Therefore, under the drive of the release shaft motor 15, the lifting plate 105 performs periodic lifting and lowering motion; the height of the bearing fixing seat 101 is adjusted by the bearing seat height adjustment stud 103. Air springs 2 are provided on both sides of the lifting plate 105. The air springs 2 are fixed on the equipment housing 17 through air spring seats 106. The air spring seats 106 are connected to the air spring pressure regulating valve 16 arranged on the equipment housing 17 to control the pressure of the air spring 2.

Both ends of the lifting shaft 24 are provided with fixed blocks 202 for fixedly connecting the lifting plate 105, the left pressure wheel 7 is slidably sleeved on the lifting shaft 24 through the left pressure wheel brake pad 206, and a through hole is provided in the lifting shaft 24 for inserting the release shaft airbag tube 203, one end of the release shaft airbag tube 203 enters and exits air through the release shaft rotary joint 201, and the other end of the release shaft airbag tube 203 is sealed with a release shaft airbag tube plug 204; a pressing groove 205 is provided on the outer wall of the lifting shaft 24 along its length direction, and the wall of the release shaft airbag tube 203 expanded by gas presses the left pressure wheel brake pad 206 and the left pressure wheel 7 through the pressing groove 205, thereby fixing the left pressure wheel 7. After the left pressure wheel 7 moves on the lifting shaft 24 and adjusts its position, the release shaft rotary joint 201 is opened, and the airflow enters the release shaft airbag tube 203 to expand and thicken it. The tube wall of the release shaft airbag tube 203 presses against the left pressure wheel brake pad 206, so that the left pressure wheel 7 remains in a fixed locked state under the clamping force of the left pressure wheel brake pad 206.

One end of the driving shaft airbag tube 302 is connected to the driving shaft rotary joint 301 installed on the driving shaft fixing seat 307 to achieve air inlet and outlet. The other end of the driving shaft airbag tube 302 is sealed with a driving shaft airbag tube plug 306. The left roller 8 is slidably mounted on the driving shaft 303 through the driving shaft roller brake pad 305. A second pressing groove 308 is provided on the outer wall of the driving shaft 303 along its length direction. The wall of the driving shaft airbag tube 302 expanded by gas presses the driving shaft roller brake pad 305 and the left roller 8 through the second pressing groove 308, thereby fixing the left roller 8. The driving shaft 303 is supported on the fixed side 19 of the device housing 17 through the driving shaft bearing 304. After the left roller 8 moves on the driving shaft 303 and adjusts its position, the driving shaft rotary joint 301 is opened, and the airflow enters the driving shaft airbag tube 302 to expand and thicken it. The tube wall of the driving shaft airbag tube 302 presses against the driving shaft roller brake pad 305, so that the left roller 8 remains in a fixed locked state under the clamping force of the driving shaft airbag tube 302.

[0053] The working process of the present invention is as follows: first, according to the actual thickness of the raw material to be fed, the left track cover switch 3 and the right track cover switch 4 are started, and the cover gap adjustment hand wheel 10 is rotated at the same time to adjust the cover gap 509 between the left track 9 and the right track 12. After the gap adjustment is completed, the left track cover switch 3 and the right track cover switch 4 are closed. Then, the width between the left track 9 and the right track 12 is controlled by the left hand wheel 5 or the right hand wheel 6 to match the different widths of the raw materials to be fed. After adjusting the track width and the cover gap, the raw material to be fed is placed in the cover gap between the left track 9 and the right track 12 until it passes through the feeding driving wheel 11. Finally, the air spring pressure regulating valve 16 is adjusted according to the thickness of the raw material to be fed so that the air spring 2 has a suitable clamping pressure.
