The frame 10 includes two wall panels, and a swing arm shaft 31 is provided between the two wall panels. Two feeding swing arms 32 are provided on the swing arm shaft 31. One end of the swing arm shaft 31 is connected to a first transmission mechanism 33, and the first transmission mechanism 33 is connected to a first drive mechanism 34. The end of the feeding swing arm 32 away from the swing arm shaft 31 is provided with a hook 321. The rear side of the wall panel is provided with an arc surface 111. The wall panel is provided with a relief groove 112 at the upper end of the arc surface 111. Two support rollers 1 are provided on one side of the relief groove 112. 13. The feeding roller 21 is provided with a limiting boss 211 on the inner side of the feeding swing arm 32. The limiting boss 211 is used to facilitate the alignment of the feeding roller 21 and the feeding swing arm 32 during feeding. The first drive mechanism 34 drives the swing arm shaft 31 to rotate through the first transmission mechanism 33 and drives the feeding swing arm 32 to swing up and down. During feeding, the feeding swing arm 32 is raised, and the feeding roller 21 is located at the hook part 321 of the feeding swing arm 32. After the feeding swing arm 32 drives the feeding roller 21 to move upward along the arc surface 111 to the upper limit, the feeding roller 21 rolls downward along the feeding swing arm 32 until it abuts against the support roller 113.

[0024] The first transmission mechanism 33 includes a sector gear 331 connected to the swing arm shaft 31 and a motor gear 332 meshing with the sector gear 331. The first drive mechanism 34 includes a first motor 341 and a first reducer 342. The output shaft of the motor gear 332 and the first reducer 342 are connected.

[0025] The frame 10 is provided with a positioning mechanism 40 above the support rollers 113. The positioning mechanism 40 includes a pressure shaft connecting rod 41, a pressure shaft roller 42, and a first cylinder 43. The middle part of the pressure shaft connecting rod 41 is rotatably connected to the frame 10. The pressure shaft roller 42 is located at the lower part of the pressure shaft connecting rod 41. The piston rod of the first cylinder 43 is connected to the upper part of the pressure shaft connecting rod 41. The cylinder body of the first cylinder 43 is rotatably connected to the frame 10. Figure 3 As shown, during feeding, the pressure roller 42 and the feeding roller 21 abut against each other, as... Figure 4 As shown, during material change, the cylinder drives the pressure shaft connecting rod 41 to rotate and drives the pressure shaft roller 42 to rise, causing the pressure shaft roller 42 to disengage from the discharge roller 21.

[0026] The frame 10 is equipped with a fine-tuning mechanism 50. The fine-tuning mechanism 50 includes two slide rods 51 fixedly connected to the frame 10, an adjusting seat 52 sleeved on the two slide rods 51 and slidable along the slide rods 51, a fixing plate 53 disposed at the outer end of the slide rods 51, and a screw 54 rotatably connected to the fixing plate 53. The screw 54 is threadedly connected to the adjusting seat 52, and the screw 54 does not move axially relative to the fixing plate 53. Specifically, as shown... Figure 2 As shown, the screw 54 has a step 541 on the inner side of the fixed plate 53. A thrust bearing 55 is sleeved on the screw 54 between the step 541 and the inner side of the fixed plate 53. Another thrust bearing 55 is sleeved on the screw 54 on the outer side of the fixed plate 53. A nut 56 is connected to the screw 54 and abuts against the end face of the thrust bearing 55 on the outer side of the fixed plate 53 away from the fixed plate 53. A handle 57 is provided at the outer end of the screw 54. The adjusting seat 52 has a limiting groove 521. One end of the feeding roller 21 has a limiting shaft section 212. The diameter of the limiting shaft section 212 is smaller than the shaft sections at both ends. When feeding, the limiting shaft section 212 is set in the limiting groove 521. When not feeding, by rotating the screw 54, the adjusting seat 52 slides along the slide rod 51. The adjusting seat 52 drives the feeding roller 21 to move axially, which facilitates fine adjustment of the position of the feeding roller 21 left and right when not feeding.

[0027] The feeding roller 21 is equipped with two baffles 22. The feeding roller 21 has a central air-expanding shaft with pneumatic radial protrusions. The baffles 22 have axially oriented through grooves 221. The protrusions and through grooves 221 engage to connect the baffles 22 and the feeding roller 21. The air-expanding shaft is existing technology, where the expansion and contraction of keyways or protrusions on the shaft surface are controlled by inflation and deflation to fix or release the tubing fitted onto the shaft. The baffles 22 are positioned on both sides of the material to ensure neat material distribution during feeding.

[0028] The frame 10 has a traction roller 61 and a pressure roller 62 at the front. The traction roller 61 is connected to a second drive mechanism 63 that drives its rotation, and the pressure roller 62 is connected to a third drive mechanism 64 that drives it to move closer to and away from the traction roller 61. A guide roller 65 is provided between the feed roller 21 and the traction roller 61. The feed roller 21 is connected to a magnetic powder brake 23 through a second transmission mechanism 24. The traction roller 61, pressure roller 62, guide roller 65, second drive mechanism 63, and third drive mechanism 64 can all adopt existing structures. In this embodiment, the second drive mechanism 63 includes a second motor 631 and a second reducer 632, and the third drive mechanism 64 includes a second cylinder 641 and a pressure roller swing arm 642. The middle part of the pressure roller swing arm 642 is rotatably connected to the frame 10, the rear end is connected to the piston rod of the second cylinder 641, and the front end is connected to the pressure roller 62. The second cylinder 641 drives the pressure roller swing arm 642 to rotate, causing the pressure roller 62 to move closer to and away from the traction roller 61.

[0029] The second transmission mechanism 24 includes a roller gear 241 mounted on the feeding roller 21, a brake gear mounted on the output shaft of the magnetic powder brake 23, and an intermediate gear 242 positioned between the roller gear 241 and the brake gear, meshing with both gears respectively. The magnetic powder brake 23 is existing technology and can be an FZK type. The magnetic powder brake 23 can apply a certain load torque to the feeding roller 21 through the second transmission mechanism 24, making the feeding process smoother.

[0030] When loading or changing materials, move the material to the rear of the frame 10, release the positioning mechanism 40 from limiting the feeding roller 21, remove the feeding roller 21, release the air shaft from limiting the baffle 22, remove one side of the baffle 22, insert the air shaft into the material, and then put the baffle 22 back in. Turn on the air shaft to clamp the material and the baffle 22, move the feeding roller 21 between the two feeding swing arms 32, start the first motor 341 to make the feeding swing arm 32 drive the feeding roller 21 to rise. When the feeding roller 21 rises to the predetermined upper limit, the feeding roller 21 rolls down along the feeding swing arm 32 until it abuts against the support roller 113. Then the feeding swing arm 32 descends, and the positioning mechanism 40 is activated to limit the feeding roller 21, thus completing the loading.
