Description

Technical Field

[0001] This utility model relates to the technical field of mulberry leaf processing equipment, specifically a mulberry leaf uniform cutting device. Background Technology

[0002] Silkworms begin feeding on mulberry leaves from the edges. Cutting the leaves into pieces and scattering them evenly on the silkworm tray allows the silkworms to eat and molt simultaneously, which is more scientific than feeding them directly with mulberry leaves. Currently, silkworm farmers use commercially available mulberry leaf cutters to chop the leaves before feeding. However, these cut leaves are often damaged, crushed, and clumped together, resulting in uneven distribution on the tray and making it inconvenient for the silkworms to eat.

[0003] In existing mulberry leaf uniform cutting devices, a batch of mulberry leaves are placed on a plate for cutting. Due to the stacking of mulberry leaves, their positions are misaligned, resulting in some leaves not being cut or only being cut in a small area when the cutter cuts down. This leads to uneven cutting and low cutting efficiency.

[0004] This case arose in order to resolve the aforementioned issues. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a mulberry leaf uniform cutting device, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a mulberry leaf uniform cutting device, comprising a frame, a cover plate hinged to the frame, cutters spaced apart below the cover plate, a motor inside the frame, a rotating rod connected to the upper output end of the motor, a sling plate for placing mulberry leaves connected to the upper end of the rotating rod, a sealing frame connected to the lower side of the sling plate, the rotation of the rotating rod simultaneously driving the sling plate and the sealing frame to rotate, a bushing pivotally connected to the rotating rod, the bushing being hollow inside and having an annular opening at the top, an insertion port on one side of the bushing and connected to an external air pipe, the air pipe providing negative pressure to the inside of the sealing frame through the bushing, and air holes arrayed through the sling plate, wherein the air pipe is located below the sealing frame.

[0009] Preferably, the frame is internally fixed with a covering frame and a material gathering frame, which are connected vertically and internally. A conveying mechanism is provided below the material gathering frame to separate the cut and uncut mulberry leaves into sections. The bottom of the material gathering frame is open, and the orthographic projection of the open is entirely located within the conveying mechanism. The motor is located in the middle of the covering frame.

[0010] Preferably, the cutting plate has a long groove on one side of the air hole, and the cutting blade is placed in the long groove during cutting.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1-2As shown: A mulberry leaf uniform cutting device includes a frame 1. A covering frame 2 and a material collection frame 6 are fixed inside the frame 1. The two are connected vertically and internally. A conveying mechanism is provided below the material collection frame 6 to separate the uniformly cut mulberry leaves and the uncut leaves into sections. A motor 13 is installed in the middle of the covering frame 2. A rotating rod 14 is connected to the upper output end of the motor 13. A swing plate 5 for placing mulberry leaves is connected to the upper end of the rotating rod 14. A sealing frame 12 is connected to the lower side of the swing plate 5. The rotation of the rotating rod 14 simultaneously drives the swing plate 5 and the sealing frame 12 to rotate.

[0023] A bushing 15 is pivotally connected to the rotating rod 14. The bushing 15 does not rotate with the rotating rod 14. The bushing 15 is hollow inside and has an annular opening 19 at the top. An insertion port 20 is located on one side and connects to an external air pipe 16. The air pipe 16 provides negative pressure to the interior of the sealing frame 12 through the bushing 15. The insertion port 20 is positioned below the sealing frame 12, so the connected air pipe 16 does not need to rotate. The negative pressure can be generated by a miniature vacuum pump.

[0024] The swivel plate 5 has a through-array of air holes 18, which allows a layer of mulberry leaves on the contact surface of the swivel plate 5 to be adsorbed during swishing. The mulberry leaves stacked on the upper side can be rotated out of the swivel plate 5 during rotation, thus allowing the single layer (mostly single layer) of mulberry leaves on the swivel plate 5 to be cut evenly. The rotated mulberry leaves are then placed back into the swivel plate 5 for further cutting, and this operation is repeated cyclically.

[0025] Specifically, the mulberry leaves are cut with a cutter 4. A cover plate 3 is hinged to the frame 1, and the cutter 4 is positioned at intervals below the cover plate 3. When the cover plate 3 is flipped in and closed, the cutter 4 can rotate onto the swing plate 5 for cutting. To prevent the cutter 4 from cutting the swing plate 5 and causing damage, a long groove can be opened on the side of the swing plate 5 located at the air hole 18. During cutting, the cutter 4 is placed in the long groove and can cut the mulberry leaves more completely.

[0026] The size of the swivel plate 5 and the sealing frame 12 are adapted, and the cross-section is preferably square or similar to a square, so that it will not touch the inner wall of the covering frame 2 during rotation, and can swing the mulberry leaves placed on the swivel plate 5 into the gap between it and the material collection frame 6, and then guide them downward along the covering frame 2 from the bottom of the material collection frame 6.

[0027] It should be noted that the entire orthographic projection of the bottom opening of the material collection frame 6 is located inside the transmission mechanism, allowing the falling mulberry leaves to be completely placed into the transmission mechanism for subsequent transfer.

[0028] The conveying mechanism includes two spaced-apart drive wheels and a conveyor belt 7 covering the two drive wheels. One of the drive wheels is driven by a motor 8 installed on the inner wall of the frame 1. To prevent mulberry leaves falling onto the conveyor belt 7 from falling out laterally, baffles 9 extending upwards are installed on both sides of the conveyor belt 7 to form a shield. Furthermore, a discharge plate 10 and a return plate 11, inclined downwards, are installed on both sides of the conveyor belt 7, respectively, for conveying uniformly cut mulberry leaves and uncut mulberry leaves, which can be conveyed to both sides by the conveyor belt 7.

[0029] The above-described embodiments are for illustrative purposes. Based on the above description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this utility model is not limited to the contents of the specification; its protection scope must be determined according to the claims.
