The outer wall of arc groove rod 71 is provided with an arc groove. When sleeve 72 moves left and right on its outer wall, it will drive arc groove rod 71 to rotate by pressing the inner wall of arc groove through ball block 711.

[0020] Reference Figure 2 - Figure 4 The front end of the material feeding box 3 is slidably connected to a rear baffle 74 for blocking materials. A gear 75 is fixedly connected to the front end of the rear baffle 74 for moving the rear baffle 74 up and down. The gear 75 meshes with a gear 73. When the gear 73 rotates, it drives the rear baffle 74 up and down through the gear 75. A connecting plate 712 is fixedly connected to the right end of the rear baffle 74 for moving the front baffle 76. A front baffle 76 for temporarily blocking material rods is slidably connected to the left end of the connecting plate 712. The baffle 76 slides at the bottom of the feeding box 2. When the rear baffle 74 moves upward, the first material bar will roll into the inside of the feeding box 3, while the front baffle 76 will move upward simultaneously to block the second material bar. The right end of the fixed block 77 is fixedly connected to a reset spring 79 for driving the sliding sleeve 710 to move to the right and reset. The right end of the reset spring 79 is fixedly connected to the left end of the sliding sleeve 710. The reset spring 79 will push the sliding sleeve 710 to the right at all times, and the sliding sleeve 710 slides on the inner wall of the feeding box 3.

[0021] Reference Figure 1 - Figure 3The adjustment assembly 8 includes a handle 81 for moving the front baffle 76. The left end of the handle 81 is fixedly connected to the right end of the front baffle 76, and the left end of the handle 81 is slidably connected to the right end of the connecting plate 712. By moving the handle 81, the front baffle 76 can be moved diagonally back and forth. The inner wall of the handle 81 is slidably connected to a slide plate 82 for moving the adjustment block 84. The left end of the slide plate 82 is fixedly connected to the adjustment block 84 for fixing the front baffle 76. The right end of the connecting plate 712 is provided with an adjustment groove 85 for accommodating the adjustment block 84. The adjustment groove 85 and the adjustment block 84 are adapted to each other. When the adjustment block 84 is inserted into the adjustment groove 85, the handle 81 will be fixed and cannot move. The right end of the slide plate 82 is fixedly connected to an adjustment spring 83 for pushing the slide plate 82. The right end of the adjustment spring 83 is fixedly connected to the inner wall of the handle 81. The adjustment spring 83 will push the slide plate 82 to the left at all times to drive the adjustment block 84 into the adjustment groove 85.

[0022] Working principle: When continuous feeding is required, the material bar can be placed into the feeding box 1 first. Then, the motor 5 can be started to drive the threaded rod 6 to rotate back and forth. The threaded rod 6 will drive the push plate 4 to move back and forth. When the push plate 4 moves to the left and squeezes the sliding sleeve 710, it will drive the sliding sleeve 710 and the round sleeve 72 to move to the left. The round sleeve 72 will force the arc groove rod 71 to rotate through the ball block 711. The arc groove rod 71 will drive the rear baffle 74 to move upward through the gear 73. In this way, the material bar in the first position will roll into the feeding box 3, while the front baffle 76 will move upward to block the material bar in the second position. When the push plate 4 moves to the right, it will push the material bar into the core-sliding machine. At the same time, since the sliding sleeve 710 is no longer squeezed, the return spring 79 will push the sliding sleeve 710 to move to the right. At this time, the rear baffle 74 and the front baffle 76 will move downward synchronously. The material bar will roll down along the inner wall of the feeding box 2 and contact the rear baffle 74, waiting for the next feeding.

[0023] When the size of the material bar changes, you can first start the motor 5 to drive the push plate 4 to move to the rightmost end of the threaded rod 6. At this time, the front baffle 76 will move downward and disengage from the feeding box 2. Then you can hold the handle 81 and push the slide plate 82 outward to drive the adjusting block 84 out of the adjusting groove 85. Then you can move the handle 81 diagonally to adjust the position of the front baffle 76. When it is adjusted to the appropriate position, you can release the slide plate 82. The adjusting spring 83 will push the slide plate 82 to re-lock it into the adjusting groove 85 and fix the handle 81 again.
