Description

Technical Field

[0001] The invention relates to the technical field of equipment for making mulberry leaf tea, and in particular to a mulberry cutting and conveying device for making mulberry leaf tea. Background Art

[0002] Mulberry leaves are leaves of the mulberry tree, a plant of the Moraceae family. The stems are generally upright, with many branches, yellow-brown skin, and gray-green branches. The leaves are oval or elliptical, green on the upper side, light green on the lower side, and with obvious veins. Mulberry trees are native to central and northern China, and are now cultivated in provinces and regions from the northeast to the southwest, and in the northwest to Xinjiang. They are also cultivated in Korea, Japan, Mongolia, Central Asian countries, Russia, Europe, India, and Vietnam. Mulberry leaves were first recorded in Shennong's Herbal Classic, and recorded in Yaoxinglun and Bencao Congxin that they have the functions of dispersing wind and heat, clearing the lungs and moistening dryness, cooling blood and improving eyesight. Mulberry leaves have certain antibacterial and lipid-lowering effects. The existing mulberry cutting and conveying device will cut mulberry leaves of different sizes according to different uses when cutting mulberry leaf tea, and then determine the subsequent operations according to the size of the mulberry leaves. For example, in the drying step, the large mulberry leaves have a long drying time, and the small mulberry leaves have a short drying time. When the large mulberry leaves are mixed with small mulberry leaves during drying, the small mulberry leaves will be over-dried. When the small mulberry leaves are mixed with large mulberry leaves during drying, the humidity of the large mulberry leaves will be too high, affecting the quality of the product. The existing equipment generally mixes and conveys, and then classifies and conveys through a screen or adds a screening device. However, there will always be a problem of wrong classification during screening after mixing. Therefore, there is an urgent need for a device that can directly separate the mulberry leaves and convey them when cutting mulberry leaves. Summary of the invention

[0031] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0032] Please refer to Figures 1 - 8, the present invention provides a mulberry leaf cutting and conveying device for making mulberry leaf tea, which includes a frame 1, and a mulberry leaf conveying component 2, a screening and conveying component 3, and a mulberry leaf cutting component 4 arranged on the frame 1; the mulberry leaf cutting component 4 is arranged above the mulberry leaf conveying component 2, the screening and conveying component 3 is vertically arranged below the mulberry leaf conveying component 2, and the mulberry leaf cutting component 4 includes a jet component 5, a lifting component 6, a fixed base 7, a first elastic component 8, a first knife net 9, and a second knife net 10 arranged around the first knife net 9. The fixed end of the lifting component 6 is connected to the frame 1, and the moving end of the lifting component 6 is connected to the fixed base 7; one end of the first elastic component 8 is connected to the fixed base 7, and the other end of the first elastic component 8 is connected to the first knife net 9. The distance from the first knife net 9 to the fixed base 7 is greater than the distance from the second knife net 10 to the fixed base 7, and the jet component 5 is used to jet air at the position of the second knife net 10.

[0033] In the technical solution of the present invention, the lifting component 6 drives the fixed base 7 to move downward, the first knife net 9 abuts against the mulberry leaves for cutting, then the lifting component 6 drives the fixed base 7 to continue moving downward, the first elastic component 8 is compressed, the second knife net 10 abuts against the mulberry leaves for cutting. After cutting, the lifting component 6 drives the fixed base 7 to move upward, and the second knife net 10 is separated from the mulberry leaves (the first knife net 9 continues to abut against the fixed base 7). The jet component 5 blows the shredded leaves and the mulberry leaves cut by the second knife net 10 onto the screening and conveying component 3. The mulberry leaves inside the first knife net 9 will not be blown off due to the blocking of the first knife net 9. After the first knife net 9 rises, the mulberry leaves inside the first knife net 9 are thus transported to the second collection box 32. The screening and conveying component 3 is net-shaped, small waste residues pass through the mesh conveyor belt and fall into the waste collection box, and small pieces of mulberry leaves are conveyed to the first collection box 31 through the screening and conveying component 3, so as to separately transport the mulberry leaves cut by the first knife net 9 and the second knife net 10 during mulberry leaf cutting, and prevent the problems that the cut mulberry leaves are not easy to screen and transport after being mixed and transported.

[0034] Specifically, the telescopic component is an electric telescopic rod or a pneumatic telescopic rod.

[0035] In another embodiment of the present invention, the jet component 5 includes a fixed ring 11. One side of the fixed ring 11 is connected to the fixed base 7, and the other side of the fixed ring 11 is connected to the second knife net 10. A cavity 18 is arranged in the middle of the fixed ring 11; the jet component 5 further includes a two-position three-way valve 12. The first inlet of the two-position three-way valve 12 is communicated with the air source, the outlet of the two-position three-way valve 12 is communicated with the cavity 18, the second inlet of the two-position three-way valve 12 faces the second knife net 10, and the two-position three-way valve 12 includes a valve rod 16, and the valve rod 16 is connected to the first knife net 9.

[0036] Specifically, when the first cutting net 9 and the second cutting net 10 are not moved, the second inlet of the two-position three-way valve 12 is communicated with the outlet, and the first inlet is not communicated with the outlet;

[0037] When the fixed base 7 continues to move downward and when both the first cutting net 9 and the second cutting net 10 cut the mulberry leaves, the first cutting net 9 drives the valve rod 16 to move. The second inlet of the two-position three-way valve 12 is not communicated with the outlet, and the first inlet is communicated with the outlet. The gas in the air source enters the cavity 18;

[0038] When the fixed base 7 continues to move upward, after the second cutting net 10 moves upward and when the first cutting net 9 still abuts against the mulberry leaves, the valve rod 16 moves. The second inlet of the two-position three-way valve 12 is communicated with the outlet, and the first inlet is not communicated with the outlet. The compressed gas in the cavity 18 is ejected from the cavity 18 through the second inlet. The compressed gas blows the mulberry leaf blocks and waste residues cut by the second cutting net 10 onto the screening and conveying assembly 3;

[0039] When the fixed base 7 continues to move upward, the relative positions of the first cutting net 9 and the second cutting net 10 do not move and do not drive the valve rod 16 to move.

[0040] Thus, when the first cutting net 9 moves upward, the release of the compressed gas in the cavity 18 is completed. Thus, the mulberry leaf blocks inside the first cutting net 9 will not be blown off, achieving the separation effect.

[0041] By providing the two-position three-way valve 12 and the cavity 18, it can be realized that when the second cutting net 10 presses down, the jetting device 5 does not jet, preventing the mulberry leaves from being blown around. Only after the second cutting net 10 moves upward and when the first cutting net 9 still abuts against the mulberry leaves, the jetting device jets, so as to ensure that the complete mulberry leaves inside the first cutting net will not be blown away, while the mulberry leaves outside the first cutting net 10 are blown off. After the gas in the cavity 18 is released, it will not jet continuously, thus preventing the complete mulberry leaves inside the first cutting net 9 from being blown down.

[0042] More specifically, a plurality of the two-position three-way valves 12 are provided and are evenly distributed inside the first cutting net 9.

[0043] In another embodiment of the present invention, the valve rod 16 is connected to the second cutting net 10 through an elastic member.

[0044] Specifically, through the connection of the elastic member, the valve rod 16 is elastically connected to the second cutting net 10. Since the stroke of the valve rod 16 is smaller than the stroke of the second cutting net 10, the valve rod 16 can be prevented from being damaged.

[0045] Please refer to Figure 1 and Figure 5, in another embodiment of the present invention, a petiole fixator 17 is provided on the mulberry leaf conveying assembly 2, and the petiole fixator 17 is used to fix the mulberry leaf on the mulberry leaf conveying assembly 2 when the central axis of the mulberry leaf is parallel to the diagonal of the first knife net 9.

[0046] Please refer to Figures 6 - 8 , specifically, the stacked mulberry leaves are fixed on the mulberry leaf conveying assembly 2 through the petiole fixator 17, and the central axis of the mulberry leaf is parallel to the diagonal of the first knife net 9. Since mulberry leaves are generally oval or heart-shaped, the central axis of the mulberry leaf is parallel to the diagonal of the first knife net 9, and there is more overlap between the diamond-shaped knife net and the edge of the oval mulberry leaf, thereby reducing the loss of mulberry leaves.

[0047] In another embodiment of the present invention, the petiole fixator 17 includes a magnet 13, a clamping rod 14 and a clamping block 15. The mulberry leaf conveying assembly 2 includes a chain plate 25. A guiding hole is formed in the chain plate 25. One end of the clamping rod 14 is connected to the magnet 13, and the other end of the clamping rod 14 is connected to the clamping block 15. The clamping block 15 is used to limit the sliding of the rod. A fixing groove is formed in the cross section of the end of the clamping rod 14 connected with the clamping block 15. The fixing groove is used to fix the petiole, and the side of the fixing groove is parallel to the diagonal of the first knife net 9.

[0048] Specifically, since the petiole is generally located on the central axis of the mulberry leaf, when the petiole is bent, the petiole is cut short, and the position close to the mulberry leaf is reserved, so as to ensure that the petiole is located on the central axis of the mulberry leaf. Thus, by determining the direction of the fixing groove for fixing the petiole, the central axis of the mulberry leaf can be fixed. At the same time, the fixing groove can fix the stacked mulberry leaves. After the mulberry leaves are picked, they are manually sorted and stacked, and then the equipment of the present application is used.

[0049] More specifically, when the clamping block 15 of the petiole fixator 17 is below the magnet 13 (i.e., on the lower chain plate conveyor belt), under the action of gravity, the clamping rod 14 slides downward, and the magnet 13 is magnetically attracted to the chain plate 25. When the chain plate 25 continues to rotate to the position where the mulberry leaves are placed (i.e., on the upper chain plate conveyor belt), since the magnet 13 and the chain plate 25 are magnetically attracted, the clamping rod 14 will not move. The staff clamps the petiole of the mulberry leaf in the fixing groove. When reaching the position of the mulberry leaf cutting assembly 4, the second knife net 10 moves downward to press down the clamping rod 14. When the downward pressure is greater than the suction force of the magnet 13, the clamping rod 14 moves downward, and the clamping block 15 at one end of the clamping rod 14 blocks the clamping rod 14, so as to prevent the clamping rod 14 from moving out of the guiding hole. Then the chain plate 25 continues to move and rotate back to the lower chain plate conveyor belt, so that under the action of gravity, the clamping rod 14 slides downward, the magnet 13 is magnetically attracted to the chain plate 25, and the clamping rod 14 repeats back and forth.

[0050] In yet another embodiment of the present invention, a contact post for abutting against the petiole holder 17 is provided on the fixed base 7. The contact post is used to abut and move the latch 15 downward when the first cutter grid 9 abuts against the mulberry leaves.

[0051] In yet another embodiment of the present invention, the mulberry leaf cutting assembly 4 further includes a second elastic telescopic member 20 and a first blade 21. One end of the second elastic telescopic member 20 is connected to the fixed base 7, and the other end of the second elastic telescopic member 20 is connected to the second cutter grid 10. The first blade 21 is fixed on the fixed base 7. The first blade 21 is disposed within the grid of the first cutter grid 9, and both ends of the first blade 21 abut against the side walls of the grid where it is located. The distance from the second cutter grid 10 to the fixed base 7 is greater than the distance from the first blade 21 to the fixed base 7.

[0052] Specifically, the first cutter grid 9 abuts against and cuts the mulberry leaves. Then, the lifting member 6 drives the fixed base 7 to continue moving downward, the first elastic member 8 is compressed, and the second cutter grid 10 abuts against and cuts the mulberry leaves. When it is necessary to further cut the mulberry leaf pieces within the first cutter grid 9, the stroke of the telescopic member is adjusted, so that the telescopic member continues to move downward, the second elastic member is compressed, and the first blade 21 cuts the mulberry leaf pieces within the cutter grid.

[0053] In yet another embodiment of the present invention, the mulberry leaf cutting assembly 4 further includes an elastic telescopic rod 22, a connecting pipe 23, and a second blade 24. One end of the elastic telescopic rod 22 is connected to the fixed base 7, and the other end of the elastic telescopic rod 22 is vertically connected to the first blade 21. The connecting pipe 23 is sleeved outside the elastic telescopic rod 22. One end of the connecting pipe 23 is vertically connected to the fixed base 7, and opposite sides of the other end of the connecting pipe 23 are both connected to the second blade 24. The distance from the first blade 21 to the fixed base 7 is greater than the distance from the second blade 24 to the fixed base 7.

[0054] Specifically, the first cutter grid 9 abuts against and cuts the mulberry leaves. Then, the lifting member 6 drives the fixed base 7 to continue moving downward, the first elastic member 8 is compressed, and the second cutter grid 10 abuts against and cuts the mulberry leaves. When it is necessary to further cut the mulberry leaf pieces within the first cutter grid 9, the stroke of the telescopic member is adjusted, so that the telescopic member continues to move downward, the second elastic member is compressed, and the first blade 21 cuts the mulberry leaf pieces within the cutter grid. The lifting member 6 continues to press downward, and the elastic telescopic rod 22 contracts until the second blade 24 cuts the mulberry leaves, thereby cutting the mulberry leaves within the grid into four parts.

[0055] Specifically, the first cutter grid 9 cooperates with the vertically arranged first blade 21 and second blade 24, so as to evenly divide the mulberry pieces within the grid of the first cutter grid 9 into four equal parts.

[0056] Specifically, the first cutter grid 9 cooperates with the first cutter blade 21 to evenly divide the mulberry blocks in the grid of the first cutter grid 9 into two equal parts.

[0057] In another embodiment of the present invention, the grid area of the first cutter grid 9 is four times that of the second cutter grid 10.

[0058] In another embodiment of the present invention, the mulberry leaf conveying assembly 2 includes two chains arranged in parallel and chain plates 25 arranged between the two chains, with a gap provided between the two chain plates 25; both ends of the chain plates 25 are respectively connected to the two chains; the first driving roller 26, the second driving roller 27 and the guiding roller 28 surrounded by the two chains, and the first driving roller 26, the second driving roller 27 and the guiding roller 28 are all connected to the frame 1 through bearings; the first driving roller 26 and the second driving roller 27 are horizontally arranged, and the guiding roller 28 is arranged below the middle of the first driving roller 26 and the second driving roller 27; a motor connected to and driving the first driving roller 26.

[0059] Specifically, the first driving roller 26, the second driving roller 27 and the guiding roller 28 are provided to form a triangle for the conveyor belt, so that the space for placing the screening and conveying assembly 3 below the chain plates 25 is larger, facilitating the blowing down of the broken leaf waste residue and the small pieces of mulberry leaves cut by the second cutter grid 10 from the gap provided between the two chain plates 25.

[0060] In another embodiment of the present invention, the screening and conveying assembly 3 includes a mesh chain conveyor belt 29, a third driving roller 30, a fourth driving roller and a motor, the mesh chain conveyor belt 29 surrounds the third driving roller 30 and the fourth driving roller, the third driving roller 30 and the fourth driving roller are both connected to the frame 1 through bearings, and the motor is used to connect to and drive the third driving roller.

[0061] Specifically, the waste residue can fall through the mesh chain conveyor belt 29, while the small pieces of mulberry leaves are conveyed by the mesh chain conveyor belt 29 to the outlet for screening and conveying.

[0062] In another embodiment of the present invention, the grid area of the first cutter grid 9 is larger than that of the second cutter grid 10.

[0063] Specifically, the grid area of the first cutting net 9 is larger than that of the second cutting net 10, and the mulberry leaf area cut by the first cutting net 9 is larger than that cut by the second cutting net 10. Since mulberry leaves are generally oval or heart-shaped, if all mulberry leaves are cut into large pieces, the large pieces of mulberry leaves cut out will have uneven edges and a small number that meets the standards, resulting in serious waste of mulberry leaves. In this application, large pieces of mulberry leaves are cut from the middle of the mulberry leaves, and small pieces of mulberry leaves are cut from the periphery. The qualification rate of the small pieces of mulberry leaves on the periphery increases, which can reduce the waste of mulberry leaves. At the same time, through classification and screening, the screening pressure can be reduced, and the accuracy of the screening and transportation device can be improved.

[0064] In another embodiment of the present invention, the grid area of the first cutting net 9 is four times that of the second cutting net 10.

[0065] In another embodiment of the present invention, the grid area of the first cutting net 9 is twice that of the second cutting net 10.

[0066] In another embodiment of the present invention, a waste collection box is provided below the screening and conveying assembly 3, a first collection box 31 is provided in the outlet direction of the screening and conveying assembly 3, and a second collection box 32 is provided in the outlet direction of the mulberry leaf conveying assembly 2.

[0067] Specifically, after the mulberry leaves are cut by the mulberry leaf cutting assembly 4, when the first fixing base 7 is lifted for the first time, the second cutting net 10 is lifted, and the jet member 5 blows the broken leaves and the small pieces of mulberry leaves cut by the second cutting net 10 down to reach the screening and conveying assembly 3 and fall onto the screening and conveying assembly 3. The mulberry leaves in the first cutting net 9 will not be blown down due to the blockage of the cutting net and are thus conveyed to the second collection box 32; the screening and conveying assembly 3 is a net-chain conveyor belt, and small waste residues pass through the net chain and are conveyed and fall into the waste collection box, and the small pieces of mulberry leaves are conveyed to the first collection box 31 through the screening and conveying assembly 3.

[0068] Specifically, a guiding hopper is provided on the frame 1, and the outlet of the guiding hopper faces the waste collection box.

[0069] In another embodiment of the present invention, lockable movable wheels are provided below the frame 1 to facilitate the transportation of the equipment.

[0070] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
