Description

Technical Field

[0001] The present invention relates to the technical field of paper flattening, in particular to a seed germination paper flattening device and method. Background Art

[0002] During the papermaking process, seeds are added to the wood pulp, which can be dyed with various colors, thus producing paper containing seeds, which is called seed paper. After use, this paper can be discarded in the soil. At the right time, temperature and humidity, the seeds in the paper can germinate and grow small seedlings. Seed paper can be produced in various ways. The seeds can be sandwiched between two pieces of paper and the two pieces of paper can be combined into one with adhesive. Alternatively, seeds can be added to the pulp in the early stage of paper production. After the paper is formed, seeds can be mixed inside it. After the seed paper is produced, it needs to be flattened for easy storage and to make it more beautiful.

[0003] In the prior art, after the seed paper is produced, it is flattened by extrusion. Pressure is applied to a stack of seed paper to make the seed paper flat. Since the seed paper itself may have wrinkles, directly applying pressure to the stack of seed paper can easily cause the wrinkled parts to fold.

[0035] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings. Obviously, the described ones are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0036] Refer to Figures 1-5 , a seed germination paper leveling device, including a frame 1, and a circulation mechanism is provided on the frame 1;

[0037] The circulating mechanism includes a conveyor belt 2, on which multiple sets of clamping components are arranged for fixing the seed paper. Horizontally and radially, a plurality of air holes 3 are opened in the conveyor belt 2. Vertically above the plurality of air holes 3, a plurality of air nozzles 4 are opened. The plurality of air nozzles 4 are respectively communicated with the plurality of air holes 3. At the rear side of the frame 1, a ventilation component is provided, and the output end of the ventilation component faces the air holes 3;

[0038] At the upper and lower sides in front of the frame 1, rolling components are provided. The rolling component includes two first telescopic cylinders 5, a cross beam 6, two second telescopic cylinders 7, a support frame 8 and a plurality of pressing wheels 9. The two first telescopic cylinders 5 are vertically and fixedly installed on the frame 1. The cross beam 6 is horizontally and fixedly installed at the output ends of the two first telescopic cylinders 5. The two second telescopic cylinders 7 are horizontally and fixedly installed inside the cross beam 6. The support frame 8 is horizontally and fixedly installed at the output ends of the two second telescopic cylinders 7. The plurality of pressing wheels 9 are rotatably installed on one side of the support frame 8 close to the conveyor belt 2. When rolling, the second telescopic cylinder 7 extends, so that the support frame 8 drives the plurality of pressing wheels 9 to move to the end where the paper is clamped. Then the first telescopic cylinder 5 contracts, so that the pressing wheels 9 descend to contact the seed paper. The second telescopic cylinder 7 shortens, so that the pressing wheels 9 roll on the upper side of the seed paper to flatten the seed paper;

[0039] The circulating mechanism operates intermittently, and a transfer mechanism is provided at the upper and lower sides of the input end. The upper side of the input end is the loading position, and the bottom side is the unloading position.

[0040] Each electrical device is powered by an external power supply, and the entire device is controlled by a control terminal. Since the control terminal is a common device and belongs to the existing mature technology, the electrical connection relationship and the specific circuit structure are not described herein again.

[0041] The transfer mechanism includes a carriage 23, two third telescopic cylinders 24 and a suction cup device 25. Two guide rails 26 are horizontally and radially fixedly installed on the side surface of the frame 1. The two ends of the carriage 23 are respectively slidably embedded in the two guide rails 26. The two third telescopic cylinders 24 are both vertically arranged and are fixedly connected to the carriage 23. The suction cup device 25 is horizontally arranged and is fixedly connected to the output ends of the two third telescopic cylinders 24.

[0042] At the top of the front side of the frame 1, a paper frame 27 is fixedly installed. At the bottom of the frame 1, a receiving frame 28 is provided. At the entrance of the receiving frame 28, a roller-type conveying device 29 is inclinedly arranged. The two transfer mechanisms are connected through a transmission component.

[0043] The transmission components include a main shaft 30, a second power device 31, two gears 32, two first racks 33 and two second racks 34. The main shaft 30 is horizontally rotatably installed in two guide rails 26 and penetrates through the guide rails 26. The two gears 32 are respectively fixedly installed at both ends of the main shaft 30. The two first racks 33 are respectively fixedly installed at the bottom ends of both sides of the upper carriage 23 and are respectively meshed and connected to the upper sides of the two gears 32. The two second racks 34 are respectively fixedly installed at the top ends of both sides of the bottom carriage 23 and are respectively meshed and connected to the lower sides of the two gears 32. The second power device 31 is fixedly installed inside one of the guide rails 26, and the output end is fixedly connected to the main shaft 30.

[0044] The circulation mechanism further includes two belt pulleys 10 and a first power device 11. The two belt pulleys 10 are both rotatably installed at both ends of the frame 1 through a rotating shaft 12. The output end of the first power device 11 is fixedly connected to the rotating shaft 12 to transmit torque. The rotating shaft 12 is fixedly connected to the belt pulley 10. The conveyor belt 2 is rolling and embedded in the two belt pulleys 10 and is in a tensioned state.

[0045] The clamping components include two clamping plates 13 and a clamping plate 14. The two clamping plates 13 are horizontally and radially symmetrically fixedly arranged on the conveyor belt 2. The clamping plate 14 is made of an elastic material and is horizontally arranged. The two ends are respectively vertically slidably installed in the two clamping plates 13. Springs 15 are vertically fixedly installed on the bottom surfaces of both ends of the clamping plate 14, and the bottom ends of the springs 15 are fixedly connected to the upper side of the conveyor belt 2.

[0046] A locking component is fixedly installed on the frame 1 through a plurality of first brackets 16. The locking component includes a snap ring 17 and a plurality of rollers 18. The snap ring 17 is fixedly connected to the ends of the plurality of first brackets 16. The plurality of rollers 18 are all rolling and embedded in the upper and lower inner walls of the snap ring 17. When the clamping plate 14 moves to the bottom side of the plurality of rollers 18, it is compressed to clamp the paper.

[0047] The ventilation components include a fan 19, two diversion pipes 20 and two shunt pipes 21. The fan 19 is fixedly installed at the rear side of the frame 1. The two shunt pipes 21 are both horizontally arranged and are fixedly installed on the frame 1 through a plurality of second brackets 22, and the air outlets are all oriented towards the air holes 3. One ends of the two diversion pipes 20 close to each other are fixedly connected and communicated with the output end of the fan 19, and the other ends far away from each other are respectively fixedly connected and communicated with the two shunt pipes 21.

[0048] The snap ring 17 does not extend to the loading position and the unloading position. The plurality of pressure wheels 9 and the two shunt pipes 21 respectively correspond to the upper and lower straight sections of the conveyor belt 2 and do not extend to the loading position and the unloading position. In the clamping position where the snap ring 17 and the clamping plate 14 enter the reduced state, there is no pressure wheel 9.

[0049] When using this device to flatten the seed paper, first place the seed paper to be flattened into the paper frame 27. The suction cup device 25 on the upper side adsorbs the topmost paper. Then, the second power device 31 drives the main shaft 30 to rotate. The main shaft 30 drives the first rack 33 and the second rack 34 to move through two gears 32. The first rack 33 drives the upper carriage 23 to move, so that both sides of the adsorbed seed paper are respectively clamped into two corresponding clamping plates 13, and the end of the paper finally moves to the lower side of the clamping plate 14. After placing it properly, the conveyor belt 2 operates, so that the next pair of clamping plates 13 is aligned with the paper frame 27. The upper transfer mechanism sends a seed paper between two corresponding clamping plates 13 in sequence, so that the seed paper forms single sheets and spreads on the conveyor belt 2.

[0050] The conveyor belt 2 moves, so that the clamping plate 14 moves to the inside of the snap ring 17. Under the action of the roller 18, the clamping plate 14 is squeezed, and the spring 15 is compressed to fix and clamp the paper, and it enters the air flow area. The fan 19 operates, and sends the air flow into the two shunt pipes 21 through the diversion pipe 20. The two shunt pipes 21 introduce the air flow into the air holes 3 on the conveyor belt 2. The air holes 4 are communicated with the air holes 3. The air flow speed at the bottom side of the seed paper is large, so that the air pressure at the bottom side is relatively low. Under the action of the pressure difference, the seed paper is subjected to a downward air pressure and is initially flattened. At the same time, the air flow has a drying effect on the seed paper.

[0051] While the fan 19 is operating, the rolling and pressing assembly operates to roll and flatten the seed paper. The moving direction of the rolling and pressing is the same as the air flow direction. The air flow and the clamping plate 14 cooperate to have a certain pulling effect on the seed paper, weakening the wrinkles. The pressing wheel 9 moves along the air flow direction to roll and press the seed paper to achieve the final flattening of the seed paper. The conveyor belt 2 moves intermittently, and each seed paper will be rolled and pressed multiple times to achieve complete flattening. Moreover, the conveyor belt 2 has a certain elasticity and cooperates with the rolling and pressing to have a certain protective effect on the seeds, which can effectively prevent the seeds from being damaged and ensure the production quality of the seed paper.

[0052] Through the above method, single-sheet laying of the seed paper can be realized, which can effectively avoid the adverse effects of stacking wrinkles on flattening. Through the air flow, the seed paper is flattened by the pressure difference, and the seed paper will be rolled and pressed multiple times during the whole process, so that the seed paper is fully flattened.

[0053] Under the intermittent operation and movement of the conveyor belt 2, the seed paper is moved to the output end at the bottom, i.e., the upper side of the drum conveyor device 29. At the same time, the clamping plate 14 disengages from the snap ring 17 to unlock the paper. The transfer mechanism at the bottom adsorbs the paper, and the transmission component operates, causing the transfer mechanism at the bottom to move outward, extracting the flattened seed paper from between the two clamping plates 13. The end of the seed paper lands on the drum conveyor device 29, and then the suction cup device 25 at the bottom releases the adsorption. The drum conveyor device 29 guides the unloaded seed paper into the receiving frame 28, completing the entire flattening process.

[0054] When the transmission component operates, the transfer mechanism on the upper side moves inward, and the transfer mechanism on the bottom side moves outward, enabling the spreading and unloading of the seed paper to be carried out simultaneously, and the entire process is automatically completed, improving the flattening efficiency.

[0055] A method for producing seed paper using the above device includes:

[0056] S1: Loading, stacking the seed paper to be flattened in the paper frame 27;

[0057] S2: Spreading, the equipment operates intermittently, and the transfer mechanism on the upper side spreads the seed paper into the corresponding clamping components in sequence to achieve single-page separation of the seed paper;

[0058] S3: Clamping and fixing, the conveyor belt 2 moves, causing the seed paper to move to the area of the locking component to fix the end of the seed paper and prevent the seed paper from moving during the flattening process;

[0059] S4: Ventilation, moving to the airflow area, ventilating through the air holes 3, generating a pressure difference above and below the seed paper to achieve preliminary flattening and simultaneous air drying;

[0060] S5: Rolling, moving to the area of the rolling component, the pressing wheel 9 rolls on the upper side of the seed paper along the airflow direction to thoroughly flatten the seed paper;

[0061] S6: Multiple rollings, the equipment operates intermittently, causing the rolling component to roll the seed paper multiple times to achieve more thorough flattening of the seed paper;

[0062] S7: Unloading, the flattened seed paper moves to the area of the lower transfer mechanism and simultaneously exits the area of the locking component, and the moving component at the bottom unloads the flattened seed paper.

[0063] Throughout the process, the seeds are spread in sequence, flattened by the airflow pressure difference, and flattened multiple times by rolling, enabling the seed paper to be fully flattened.

[0064] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
