To sort the bamboo sheets into single sheets, a bamboo sheet sorter is required. The bamboo sheet sorter usually includes two rotating shafts arranged up and down. Sprockets are provided on the rotating shafts. Chains are sleeved on the sprockets on the two rotating shafts. A number of pick-up handles are evenly arranged on the outer circumference of the chains. A carrier is arranged on one side of the chains to carry a pile of bamboo sheets. By rotating the rotating shafts, the chains drive the pick-up handles to move upward to pick up the bamboo sheets on the carrier. The pick-up of the pick-up handles is used to sort the pile of bamboo sheets. However, after the pick-up handles pick up all the bamboo sheets on the carrier within the pick-up range of the pick-up handles, it is still necessary to manually push the bamboo sheets at other positions on the carrier to the range that can be picked up by the pick-up handles. Through manual feeding, the labor intensity of the staff is relatively large, and it is not conducive to the automated development of bamboo sheet processing. Summary of the Utility Model

Detailed Description of the Invention

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0017] Embodiment 1

[0018] An automatic blanking mechanism includes a support frame 1, a carrier frame 2 and a driving assembly 3. The carrier frame 2 includes a sliding frame body 21, a carrier plate 22 and extension rods. Two rollers 211 arranged at intervals along the width direction are rotatably provided at both ends of the sliding frame body 21. The support frame 1 includes a cross bar 11 and two side plates 12. The two side plates 12 are arranged in parallel and symmetrically. One end of the cross bar 11 is fixedly connected to one side plate 12, and the other end of the cross bar 11 is fixedly connected to the other side plate 12. Concave chutes 121 matching the rollers 211 are provided on the opposite side walls of the two side plates 12. The rollers 211 at both ends of the sliding frame body 21 are respectively clamped into the two chutes 121 and slide therein. The chutes 121 are inclined so that the sliding frame body 21 is inclined. The inclination angle of the sliding frame body 21 is 10 - 30°, preferably 15°. Bottom plates 13 are provided at the bottoms of the two side plates 12 to increase the contact area with the ground, making the side plates 12 stable and not easy to shake. The driving assembly 3 includes a motor frame 31, a servo motor 32, a connecting block 33, a hinge shaft 34, a spherical eye joint 35 and a connecting member 36. The motor frame 31 is located on one side of the sliding frame body 21 and below the sliding frame body 21. The servo motor 32 is fixed on the motor frame 31 and is placed horizontally parallel to the sliding frame body 21. One end of the connecting block 33 is fixedly connected to the driving shaft of the servo motor 32, and the other end of the connecting block 33 is fixedly connected to the hinge shaft 34. The hinge shaft 34 is parallel to the driving shaft of the servo motor 32. One end of the spherical eye joint 35 is hinged to the hinge shaft 34, and the other end of the spherical eye joint 35 is hinged to the connecting member 36. The connecting member 36 is fixedly connected to the bottom of the sliding frame body 21. By driving the servo motor 32, the connecting block 33 drives the hinge shaft 34 to rotate around the driving shaft of the servo motor 32. By the hinge shaft 34 rotating around the driving shaft of the servo motor 32, one end of the spherical eye joint 35 hinged to the connecting member 36 makes an arc motion. Through the limit of the chute 121, the connecting member 36 drives the sliding frame body 21 to reciprocate along the length direction of the chute 121. Since the chute 121 is inclined, a high-level drop is continuously generated when the sliding frame body 21 reciprocates along the length direction of the chute 121.

[0019] There are two extension rods 23. The two extension rods 23 are placed at both ends of the top surface of the sliding frame 21, and the lengths of the two extension rods 23 extend outward from one side of the sliding frame 21. The extension rods 23 are designed as cylindrical rods. The cylindrical rods are convenient for reducing the contact area with the bamboo slices, reducing the friction and facilitating the sliding of the bamboo slices on the extension rods 23. The bearing plate 22 is fixed to the top of the extension rods and is directly above the sliding frame 21 and parallel to the sliding frame 21 for supporting the stacked bamboo slices. A number of cushion blocks 212 arranged along the length direction are also fixed on the top surface of the sliding frame 21. The number of cushion blocks 212 abuts against the bottom surface of the bearing plate 22, increasing the bearing capacity of the bearing plate 22, so that the stacked bamboo slices are not easily crushed the bearing plate 22. When the sliding frame 21 reciprocates along the length direction of the sliding groove 121, a high-level drop is continuously generated, driving the bearing plate 22 to continuously generate a high-level drop, causing the bamboo slices on the bearing plate 22 to vibrate, continuously falling onto the extension rods 23 to be supported by the extension rods 23, and sliding along the inclined direction on the extension rods 23.

[0020] The implementation principle of Embodiment 1 is as follows: The bearing frame 2 is located on one side of the upward transmission direction of the picking handle, and the picking handle penetrates between the two extension rods 23. The driving component 3 is used to drive the sliding frame 21 to reciprocate along the length direction of the sliding groove 121, so that the sliding frame 21 drives the bearing plate 22 to continuously generate a high-level drop, causing the bamboo slices on the bearing plate 22 to vibrate. The bamboo slices fall onto the extension rods 23 along the inclined direction of the bearing plate 22. The extension rods 23 guide the bamboo slices to the picking range of the picking handle, realizing the automatic blanking of the bamboo slices, eliminating the need for manual stacking of the bamboo slices and reducing the labor intensity of the staff.

Circular grooves 122 matching the rollers 211 are recessed on the opposite side walls of the two side plates 12. Slots 123 are opened on the side walls of the two side plates 12 on one side of the circular grooves 122. The slots 123 penetrate upward through the tops of the side plates 12. One roller 211 at one end of the sliding frame body 21 is engaged in the circular groove 122 of one side plate 12, and the other roller 211 abuts against the bottom of the slot 123 of this side plate 12 to obtain support. One roller 211 at the other end of the sliding frame body 21 is engaged in the circular groove 122 of the other side plate 12, and the other roller 211 abuts against the bottom of the slot 123 of this side plate 12 to obtain support. The bottom of the slot 123 is higher than the circular groove 122, so that the sliding frame body 21 is inclined. The inclination angle of the sliding frame body 21 is 10 - 30°, preferably 15°. Bottom plates 13 are provided at the bottoms of the two side plates 12. By means of the bottom plates 13, the contact area with the ground is increased, so that the side plates 12 are stable and not easy to shake. The driving assembly 3 includes a motor frame 31, a servo motor 32, a connecting block 33, a hinge shaft 34, a ball eye joint 35 and a connecting member 36. The motor frame 31 is located on one side of the sliding frame body 21 and below the sliding frame body 21. The servo motor 32 is fixed on the motor frame 31 and is placed horizontally and parallel to the sliding frame body 21. One end of the connecting block 33 is fixedly connected to the driving shaft of the servo motor 32, and the other end of the connecting block 33 is fixedly connected to the hinge shaft 34. The hinge shaft 34 is parallel to the driving shaft of the servo motor 32. One end of the ball eye joint 35 is hinged to the hinge shaft 34, and the other end of the ball eye joint 35 is hinged to the connecting member 36. The connecting member 36 is fixedly connected to the bottom of the sliding frame body 21 near one side of the slot 123. By driving the servo motor 32, the connecting block 33 drives the hinge shaft 34 to rotate around the driving shaft of the servo motor 32. By the hinge shaft 34 rotating around the driving shaft of the servo motor 32, one end of the connecting member 36 hinged by the ball eye structure makes an arc motion. By engaging the rollers 211 in the circular grooves 122, the sliding frame body 21 is hinged to the side plates 12. The sliding frame body 21 is limited by the circular grooves 122, so that the ball eye joint 35 drives the sliding frame body 21 to swing up and down with the rollers 211 as the axis, continuously generating a high-level drop.

[0023] There are two extension rods 23. The two extension rods 23 are respectively placed at both ends of the top surface of the sliding frame body 21, and the lengths of the two extension rods 23 extend outward from one side of the sliding frame body 21. The extension rods 23 are designed as cylindrical rods.

The bearing plate 22 is fixed to the top of the extension rod and is directly above the sliding frame body 21 and parallel to the sliding frame body 21 for supporting the stacked bamboo slices. A number of cushion blocks 212 arranged along its length direction are also fixed on the top surface of the sliding frame body 21. The number of cushion blocks 212 abuts against the bottom surface of the bearing plate 22 to increase the bearing capacity of the bearing plate 22, so that the stacked bamboo slices are not easily crushed to the bearing plate 22. The sliding frame body 21 swings up and down with the roller 211 as the axis, continuously generating a high-level drop, so as to drive the bearing plate 22 to continuously generate a high-level drop, making the bamboo slices on the bearing plate 22 vibrate, continuously falling onto the extension rods 23 to be supported by the extension rods 23, and sliding along the inclined direction on the extension rods 23.

[0024] The implementation principle of Embodiment 2 is as follows: The bearing frame 2 is located on one side of the upward transmission direction of the picking plate, and the picking handle penetrates between the two extension rods 23. The sliding frame body 21 is driven by the driving assembly 3 to swing up and down with the roller 211 as the axis, so that the sliding frame body 21 drives the bearing plate 22 to continuously generate a high-level drop, making the bamboo slices on the bearing plate 22 vibrate. The bamboo slices fall onto the extension rods 23 along the inclined direction of the bearing plate 22. The extension rods 23 guide the bamboo slices to the picking range of the picking handle, realizing automatic blanking of the bamboo slices, without the need to manually push the bamboo slices, reducing the labor intensity of the staff.
