Description
Technical Field
[0001] This invention relates to the field of agricultural production technology, specifically to a novel rice seedling tray and its manufacturing method. Background Technology
[0002] With the successful development of biodegradable biomaterial rice seedling trays, rice seedling transplanting technology has begun to be experimentally applied in agricultural production. Because the seedlings can receive effective nutrients in the nutrient pots after transplanting, there is no slow seedling period, and the seedlings grow and develop well, increasing the yield per unit area of rice. However, biomaterial rice seedling trays have problems such as complex processing technology, high manufacturing cost, and long degradation cycle, which urgently need to be solved. To this end, Chinese patent disclosed a complete set of equipment for processing paper seedling trays for rice seedlings, application number 201510955207.9. This patent can process paper materials with hot melt adhesive properties into rice seedling trays, realizing the mechanized production and processing of paper seedling trays. It has the characteristics of novel and reasonable structure, convenient operation, reliable use, good operation quality, and high operation efficiency.
[0003] However, the efficiency of subsequent stacking of embryo materials in this patent is too low, the feeding, cutting and unloading processes are time-consuming, and the one-way transportation wastes too much time, resulting in a decrease in the overall production efficiency. Therefore, this invention provides a new type of rice seedling tray and its manufacturing method to meet people's needs. Summary of the Invention
[0004] This invention provides a novel rice seedling tray and its manufacturing method, which can effectively solve the problems mentioned in the background art, such as low efficiency of subsequent stacking of embryo materials, excessive time consumption in the feeding, cutting and unloading processes, unidirectional transportation, and excessive time wastage, resulting in reduced work efficiency of the entire production process.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel rice seedling tray and its manufacturing method, comprising the following steps:
[0006] S1. Material preparation: Take the stacked blanks and place them on the movable long plate located at the top of the frame. The number of stacked blanks is the same as the number of storage boxes. One stacked blank is placed in each storage box.
[0007] S2, Traction: The left or right take-up motor drives the left and right take-up shafts to rotate, pulling the moving plate along the guide groove.
[0008] S3, Positioning: The laser emitted by the laser emitter is captured by the laser receiver, and its corresponding placement frame moves to below the slicing blade, stopping the traction movement;
[0009] S4. Slicing: The hydraulic telescopic rod drives the slicing blade to descend, cutting the stacked blanks in the storage frame into slices. After completion, the hydraulic telescopic rod drives the slicing blade to rise back to its original position.
[0010] S5, Repositioning: The left or right take-up motor drives the left and right take-up shafts to rotate again, causing the moving longboard to move forward a certain distance and then stop.
[0011] S6. Material Retrieval: Move the next placement frame and stack of embryo material to the bottom of the slicing blade for slicing. The staff can remove the sheet-like embryo material after the previous slicing is completed and load the stack of embryo material for subsequent slicing.

A left take-up motor is fixedly installed at the top of one hydraulic adjusting rod, and a right take-up motor is fixedly installed at the top of the other hydraulic adjusting rod. The output shafts of the left and right take-up motors are both fixedly connected to drive gears. A left take-up shaft is installed at the middle of the top of one of the mounting bases, and a right take-up shaft is installed at the middle of the top of the other mounting base. A left traction rope is wound around the middle of the left take-up shaft, and a right traction rope is wound around the middle of the right take-up shaft. A transmission gear is fixedly connected to one end of both the left and right take-up shafts. A fixed bracket is fixedly installed at one end of the top of the mounting base. A positioning shaft is fixedly installed at the top of the fixed bracket, and a limit wheel is rotatably installed in the middle of the positioning shaft.
[0015] Fixed plates are fixedly connected to the bottom of both ends of the top of the frame. A fixed frame is fixedly connected to one end of the bottom of the fixed plate.

A hemispherical contact block is fixedly installed in the middle of the movable plate away from the mounting seat. A fixing block is fixedly installed in the middle of the frame at the position corresponding to the laser emitter. An arc-shaped metal spring is fixedly installed at one end of the fixing block.
[0017] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.
[0018] 1. Equipped with a bidirectional traction mechanism, the left and right winding motors alternately operate on both sides, driving the left and right winding shafts to rotate and wind the left and right traction ropes. This pulls the moving long plate to both sides, pushing the corresponding placement frames under the slicing blade for slicing. The seedling tray embryos are cut into sheet-like embryos of the same thickness. Multiple placement frames can be used, allowing for simultaneous loading and unloading. Loading and unloading can be performed on both sides of the slicing blade. After cutting in the placement frame, the frame is pulled forward, and the operator removes the cut sheet-like embryos and places the embryos to be cut into the placement frame. When the moving long plate moves in the opposite direction, the placed embryos are pulled under the slicing blade for cutting. Loading and unloading can be performed in both directions, and the operation can be switched according to the direction of movement, effectively improving work efficiency and reducing waiting time for the same operation.
[0019] Simultaneously, the extrusion rod moves along with the moving long plate. When it reaches the end, it extrudes the movable rod and the push block, compressing the extrusion spring. The push block and the contact pad then contact the contact switch, controlling the hydraulic adjustment rod in the corresponding direction. After the moving long plate reaches the end, the left and right take-up motors alternate their operation, thereby raising or lowering the corresponding left or right take-up motor. This allows the drive gear on one side to mesh with the transmission gear and rotate synchronously, while the drive gear on the other side remains away from the transmission gear and does not obstruct the rotation operation. The control method is simple, and automatic operation control is performed based on the position of the moving long plate.
[0020] 2. By using a laser receiver that corresponds to a laser emitter that moves below the slicing blade, a positioning and detection function is achieved. After the laser receiver captures the emitted laser, it promptly transmits the information and controls the left and right take-up motors. The left and right take-up motors then drive the moving plate to a predetermined position and stop, making the pulling position more accurate.
[0021] Simultaneously, the hemispherical contact block is squeezed by the arc-shaped metal spring during movement, causing the buffer pad to press on the control button, activating the laser emitter, and then emitting a laser downward for positioning and detection. Only the laser emitter that moves to the corresponding position under the slicing tool will be activated, while other laser emitters will remain off, reducing energy consumption during idle periods and realizing the concept of energy conservation and environmental protection in production.
[0022] 3. A monitoring and protection mechanism is installed, which uses the friction wheel and friction pad to stabilize the left and right take-up shafts through friction. This ensures that the left and right take-up shafts will only rotate when pulled by the left and right traction ropes, improving their stability and making the rotation angle more accurate. This prevents the left and right take-up shafts from shaking when being pulled, which could cause them to rotate excessively and loosen the left and right traction ropes, thus affecting subsequent rotation and pulling operations.
[0023] The friction pad is embedded in the arc-shaped limiting frame and positioned by the limiting arc-shaped block. The mounting block is fixed in the positioning block, making the installation method simple. The other side of the friction pad is in contact with the arc-shaped fitting block, so that the friction pad is limited by both sides, making the installation more stable. The installation and replacement methods are extremely simple.
[0024] 4. The contact wheel comes into contact with the left and right traction ropes, which compress the wheel. The positioning frame and the contact pad apply pressure to the pressure sensor, which detects that the left and right traction ropes are taut and tightly compressed. This allows for monitoring of the left and right traction ropes. When the left and right traction ropes become loose, a significant difference in pressure is detected by the pressure sensor, allowing staff to promptly identify and adjust the system. The system also monitors the friction pads. When the friction pads wear down and can no longer maintain contact with the friction wheel, the left and right traction ropes may become loose, alerting staff to replace or adjust them in a timely manner.
[0025] In summary, through the bidirectional traction mechanism and monitoring and protection mechanism, the moving long plank is pulled by the left and right traction ropes. The friction generated by the friction wheel and friction pad limits the left and right winding shafts, ensuring that the winding of the left and right traction ropes is not problematic. The pressure sensor monitors the tautness of the left and right traction ropes by sensing the pressure, which also maintains the traction of the left and right traction ropes, improves the stability of traction, and allows for timely detection and maintenance when problems occur.

[0043] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0044] Example: Figure 1 As shown, the present invention provides a technical solution, a method for manufacturing a novel rice seedling tray, comprising the following steps:
[0045] S1. Material preparation: Take the stacked blanks and place them on the movable long plate 602 located at the top of the frame 1. The number of stacked blanks is the same as the number of storage boxes 603. Each storage box 603 contains one stacked blank.
[0046] S2, Traction: The left take-up motor 608 or the right take-up motor 609 drives the left take-up shaft 611 and the right take-up shaft 612 to rotate, pulling the moving long plate 602 to slide along the guide groove 601;
[0047] S3, Positioning: The laser emitted by the laser emitter 627 is captured by the laser receiver 628, and its corresponding placement frame 603 moves to below the slicing blade 4, stopping the traction movement;
[0048] S4, Slicing: The hydraulic telescopic rod 3 drives the slicing blade 4 to descend, cutting the stacked blank in the storage frame 603 into sliced blanks. After completion, the hydraulic telescopic rod 3 drives the slicing blade 4 to rise back to its original position.
[0049] S5. Repositioning: The left take-up motor 608 or the right take-up motor 609 drives the left take-up shaft 611 and the right take-up shaft 612 to rotate again, so that the moving plate 602 moves forward a certain distance and then stops.
[0050] S6. Material Removal: The next placement frame 603 and the stack of embryo material are moved to the bottom of the slicing blade 4 for slicing. The staff can remove the sheet-like embryo material after the previous slicing is completed and load the stack of embryo material for subsequent slicing. After the sheet-like embryo material is removed, the bottom is sealed to form a seedling tray.
[0051] like Figure 2-12 As shown, a mounting frame 2 is fixedly installed at the middle of the top of the frame 1. Hydraulic telescopic rods 3 are symmetrically fixedly installed on the top of the mounting frame 2. A slicing blade 4 is fixedly installed between the bottom ends of the two hydraulic telescopic rods 3. A protective cover 5 is fixedly installed in the middle of the mounting frame 2. The bottom of the hydraulic telescopic rod 3 moves through the top of the protective cover 5. The protective cover 5 wraps around the outside of the slicing blade 4. A bidirectional traction mechanism 6 is installed at both ends of the frame 1.
[0052] The bidirectional traction mechanism 6 includes a guide groove 601, a movable long plate 602, a storage frame 603, a connecting block 604, a compression rod 605, a mounting base 606, a hydraulic adjusting rod 607, a left winding motor 608, a right winding motor 609, a drive gear 610, a left winding shaft 611, a right winding shaft 612, a left traction rope 613, a right traction rope 614, a transmission gear 615, a fixed bracket 616, a positioning shaft 617, a limit wheel 618, a fixed plate 619, a fixed frame 620, a movable rod 621, a compression spring 622, a push block 623, a contact pad 624, a contact switch 625, a mounting base 626, a laser emitter 627, a laser receiver 628, a control button 629, a guide rod 630, a movable plate 631, a buffer pad 632, a hemispherical contact block 633, a fixed block 634, and an arc-shaped metal spring 635.
[0053] A guide groove 601 is provided in the middle of the frame 1. A movable long plate 602 is movably embedded in the middle of the frame 1. A storage frame 603 is fixedly installed at equal intervals on the top of the movable long plate 602. Both sides of the movable long plate 602 are movably embedded in the guide groove 601. The storage frame 603 is located below the slicing blade 4. Connecting blocks 604 are symmetrically fixedly connected to both ends of the bottom of the movable long plate 602. Extrusion rods 605 are symmetrically fixedly connected to one end of each of the two connecting blocks 604. Mounting bases 606 are installed on both sides of the bottom of the frame 1. Hydraulic adjusting rods 607 are fixedly installed at one end of the top of each of the two mounting bases 606. A left take-up motor 608 is fixedly installed at the top of one hydraulic adjusting rod 607, and a right take-up motor 609 is fixedly installed at the top of the other hydraulic adjusting rod 607. The output shafts of the left take-up motor 608 and the right take-up motor 609 are fixedly connected to drive gears 6. 10. A left take-up shaft 611 is installed at the middle of the top of one mounting base 606, and a right take-up shaft 612 is installed at the middle of the top of another mounting base 606. A left traction rope 613 is wound around the middle of the left take-up shaft 611, and a right traction rope 614 is wound around the middle of the right take-up shaft 612. A transmission gear 615 is fixedly connected to one end of both the left take-up shaft 611 and the right take-up shaft 612. A fixed bracket 616 is fixedly installed at one end of the top of the mounting base 606. A positioning shaft 617 is fixedly installed on the top of the fixed bracket 616. A limit wheel 618 is rotatably installed in the middle of the positioning shaft 617. Two drive gears 610 are located directly below the two transmission gears 615. One end of the left traction rope 613 and the right traction rope 614 are connected to the middle of the two connecting blocks 604 respectively. The left traction rope 613 and the right traction rope 614 are tightly attached to the inner side of the middle of the two limit wheels 618 respectively.
[0054] Fixed plates 619 are fixedly connected to the bottom of both ends of the top of the frame 1. A fixed frame 620 is fixedly connected to one end of the bottom of the fixed plate 619. A movable rod 621 is symmetrically and movably installed through both ends of the fixed frame 620. A compression spring 622 is sleeved on the surface of the movable rod 621. A push block 623 is fixedly connected to the middle of the movable rod 621. A contact pad 624 is fixedly bonded to the middle of the push block 623. A contact switch 625 is fixedly installed in the middle of one end of the fixed frame 620. The position of the compression rod 605 corresponds to the position of the movable rod 621. The two ends of the compression spring 622 are connected to the fixed frame 620 and the push block 623 respectively. The contact pad 624 and the contact switch 625 correspond to each other. The signal output terminals of the two contact switches 625 are connected to the signal input terminals of the two hydraulic adjustment rods 607 respectively. The left take-up motor 608 and the right take-up motor 609 alternately operate on both sides. The movement of the left and right take-up shafts 611 and 612 causes them to rotate, winding the left and right traction ropes 613 and 614. This, in turn, pulls the moving plate 602 to both sides, pushing the corresponding placement frame 603 under the slicing blade 4 for slicing. This cuts the seedling tray embryo into sheet-like embryos of the same thickness. Multiple placement frames 603 can be used simultaneously for loading and unloading. Both sides of the slicing blade 4 can be used for loading and unloading. After cutting in the placement frame 603, the frame 603 is pulled forward. The worker removes the cut sheet-like embryo and places the embryo to be cut into the placement frame 603. When the moving plate 602 moves in the opposite direction, the placed embryo is pulled under the slicing blade 4 for cutting. Loading and unloading can be performed in both directions. The operation can be switched according to the direction of movement, which effectively improves work efficiency and reduces the waiting time for the same operation.
[0055] Simultaneously, the extrusion rod 605 moves along with the moving long plate 602. When it reaches the end, it extrudes the movable rod 621 and the push block 623, compressing the extrusion spring 622. The push block 623 and the contact pad 624 contact the contact switch 625, controlling the hydraulic adjustment rod 607 in the corresponding direction. After the moving long plate 602 moves to the end, the left winding motor 608 and the right winding motor 609 alternate their operation, thereby raising or lowering the corresponding left winding motor 608 or right winding motor 609. This allows the drive gear 610 on one side to mesh with the transmission gear 615 and rotate synchronously, while the drive gear 610 on the other side is far from the transmission gear 615 and does not obstruct the rotation operation. The control method is simple, and the automatic operation control is performed according to the position of the moving long plate 602.
[0056] Mounting bases 626 are fixedly mounted at equal intervals at the bottom of the movable long plate 602. Laser emitters 627 are fixedly mounted at the bottom of the mounting bases 626. Laser receivers 628 are fixedly mounted in the middle of the frame 1. The number of laser emitters 627 is the same as the number of storage frames 603, and the positions of the laser emitters 627 correspond one-to-one with the positions of the storage frames 603. The laser receivers 628 are located directly below the slicing blade 4. The signal output terminal of the laser receiver 628 is connected to the signal input terminals of both the left take-up motor 608 and the right take-up motor 609. A control button 629 is fixedly mounted in the middle of one end of the mounting base 626. Guide rods 630 are fixedly mounted on both sides of the control button 629 at one end of the mounting base 626. A movable plate 631 is movably connected to the end of the guide rod 630. A buffer pad 632 is fixedly mounted in the middle of the movable plate 631 corresponding to one end of the mounting base 626. The middle of the movable plate 631 is away from the mounting base 626. A hemispherical contact block 633 is fixedly installed at one end of the mounting base 626. A fixing block 634 is fixedly installed at the middle of the frame 1 at the position corresponding to the laser emitter 627. An arc-shaped metal spring 635 is fixedly installed at one end of the fixing block 634. The signal output end of the control button 629 is the same as the signal input end of the laser emitter 627. The buffer pad 632 is in close contact with the surface of the control button 629. The arc-shaped metal spring 635 and the hemispherical contact block 633 are at the same horizontal height. The laser receiver 628 corresponds to the laser emitter 627 that has moved to below the slicing blade 4, which plays a role in positioning and detection. After the laser receiver 628 captures the emitted laser, it promptly reacts with the information and controls the left take-up motor 608 and the right take-up motor 609. The left take-up motor 608 and the right take-up motor 609 drive the moving long plate 602 to a certain position and then stop, making the pulling position more accurate.
[0057] Simultaneously, the hemispherical contact block 633 is squeezed by the arc-shaped metal spring 635 during movement, causing the buffer pad 632 to press on the control button 629, activating the laser emitter 627, which then emits a laser downward for positioning detection. Only the laser emitter 627 that moves to the corresponding position below the slicing blade 4 will be activated, while other laser emitters 627 will remain in the off state, reducing energy consumption in idle state and realizing the concept of energy conservation and environmental protection in production.
[0058] A monitoring and protection mechanism 7 is provided above the mounting base 606;
[0059] The monitoring and protection mechanism 7 includes a friction wheel 701, a positioning block 702, a mounting block 703, a mounting bolt 704, an arc-shaped limiting frame 705, a friction pad 706, a limiting arc-shaped block 707, an arc-shaped fitting block 708, a fixed base plate 709, a rotating seat 710, a connecting plate 711, a positioning frame 712, a fitting pad 713, a fitting wheel 714, a limiting protrusion 715, a mounting vertical plate 716, a pressure sensor 717, an inclined connecting seat 718, and a buffer spring 719.
[0060] Friction wheels 701 are fixedly connected to one end of both the left take-up shaft 611 and the right take-up shaft 612. Positioning blocks 702 are fixedly installed at one bottom end of both the left take-up shaft 611 and the right take-up shaft 612. An installation block 703 is embedded in the middle of the positioning block 702. An installation bolt 704 is installed in the middle of the installation block 703. An arc-shaped limiting frame 705 is fixedly connected to the top of the installation block 703. A friction pad 706 is embedded in the middle of the arc-shaped limiting frame 705. A limiting arc-shaped block 707 is installed on the surface of the arc-shaped limiting frame 705. Arc-shaped fitting blocks 708 are fixedly installed at the corresponding positions of the arc-shaped limiting frame 705 at one end of both the left take-up shaft 611 and the right take-up shaft 612. The top end of the friction pad 706 is in close contact with the surface of the bottom end of the friction wheel 701. 3. The mounting bolt 704 is fixed inside the positioning block 702. The limiting arc-shaped block 707 is in close contact with the surface of the friction pad 706. The back of the friction pad 706 is in contact with the arc-shaped contact block 708. The friction wheel 701 is in contact with the friction pad 706. The friction force stabilizes the left take-up shaft 611 and the right take-up shaft 612. This ensures that the left take-up shaft 611 and the right take-up shaft 612 will only rotate when pulled by the left traction rope 613 and the right traction rope 614. This improves their stability and makes the rotation angle more accurate. It also prevents the left take-up shaft 611 and the right take-up shaft 612 from shaking when pulled, causing them to rotate excessively and loosen the left traction rope 613 and the right traction rope 614, which would affect the subsequent rotation and pulling operations.
[0061] The friction pad 706 is embedded in the arc-shaped limiting frame 705 and is positioned by the limiting arc-shaped block 707. The mounting block 703 is fixed in the positioning block 702. The installation method is simple. The other side of the friction pad 706 is in contact with the arc-shaped fitting block 708, so that the friction pad 706 is limited by both sides, making the installation more stable. The installation and replacement methods are very simple.
[0062] A fixed base plate 709 is fixedly installed at the middle of one end of the top of the fixed bracket 616. A rotating seat 710 is fixedly installed at the middle of the fixed base plate 709. A connecting plate 711 is movably connected to the middle of the rotating seat 710 via a rotating shaft. A positioning frame 712 is fixedly installed on the top of the connecting plate 711. An adhesive pad 713 is fixedly bonded to one end of the positioning frame 712. An adhesive wheel 714 is fixedly connected to the other end of the adhesive pad 713. Limiting protrusions 715 are symmetrically fixedly installed on both sides of the adhesive wheel 714. The fixed base plate 709... A mounting plate 716 is fixedly installed on the top of the rotating base 710, with a pressure sensor 717 mounted on its top. An inclined connecting seat 718 is fixedly installed on the top of the fixed base plate 709, away from the mounting plate 716. A buffer spring 719 is fixedly connected to the inclined end of the inclined connecting seat 718. A contact pad 713 is tightly attached to the surface of the pressure sensor 717. A contact wheel 714 is located below the limiting wheel 618, with one end of the contact wheel 714 contacting the contact pad 713 and the contact wheel 719. 14 phases are in contact, with limiting protrusions 715 located on both sides of the contact pad 713 and the contact wheel 714. The top of the buffer spring 719 is connected to the middle of the connecting plate 711. The contact wheel 714 is in contact with the left traction rope 613 and the right traction rope 614, that is, the left traction rope 613 and the right traction rope 614 squeeze the contact wheel 714. The positioning frame 712 and the contact pad 713 exert a certain pressure on the pressure sensor 717, sensing that the left traction rope 613 and the right traction rope 614 are in a taut and tightly pressed state, thereby... The status of the left traction rope 613 and the right traction rope 614 is monitored. When the left traction rope 613 and the right traction rope 614 become loose, the pressure sensor 717 detects a significant difference in pressure. The staff can promptly capture the signal and make adjustments. The system also monitors the friction pad 706. When the friction pad 706 wears down and can no longer maintain contact with the friction wheel 701, the left traction rope 613 and the right traction rope 614 are likely to become loose, which alerts the staff and allows for timely replacement and adjustment.
[0063] The working principle and usage process of this invention are as follows: First, a hydraulic adjusting rod 607 retracts downward, pulling the right take-up motor 609 and drive gear 610 downward. This causes the corresponding drive gear 610 to move away from the transmission gear 615, thereby causing the right take-up shaft 612 to lose its limit position. Meanwhile, the drive gear 610 of the corresponding left take-up motor 608 meshes with the transmission gear 615 at the end of the left take-up shaft 611. The left take-up motor 608 drives the drive gear 610 and transmission gear 615 to rotate, and the left take-up shaft 611 winds up the left traction rope 613, pulling the movable plate 602 to move to the frame 1. At one end, the movable long plate 602 is located above the left take-up shaft 611. The extrusion rod 605 will extrude the movable rod 621, the extrusion spring 622 will be compressed, the push block 623 will move forward with the movable rod 621, the contact pad 624 will press on the surface of the contact switch 625, the contact switch 625 will transmit the signal to the hydraulic adjustment rod 607, the hydraulic adjustment rod 607 will retract downward, driving the left take-up motor 608 to descend, while the hydraulic adjustment rod 607 on the other side will extend, driving the right take-up motor 609 to rise, and the drive gear 610 at its end will mesh with the corresponding transmission gear 615 above.
[0064] At this time, the staff places the prepared seedling tray-shaped embryos into the placement frame 603 in sequence. The right winding motor 609 is started, driving the drive gear 610 to rotate continuously, meshing with the transmission gear 615, which in turn drives the right winding shaft 612 to rotate, winding the right traction rope 614 and pulling the moving plate 602 to move along the guide groove 601. After moving a certain distance, one placement frame 603 moves to below the slicing blade 4, and the mounting base 626 below this placement frame 603 corresponds to the position of the laser receiver 628. The corresponding hemispherical contact block 633 at one end contacts the arc-shaped metal spring 635. Under the pressure of the arc-shaped metal spring 635, the movable plate 631 moves along the guide rod 630. The movement of the buffer pad 632 presses the control button 629, which activates the corresponding laser emitter 627 and emits a laser downwards until the emitted laser is captured by the laser receiver 628 and the signal is transmitted. The right take-up motor 609 stops rotating, indicating that the stack of blanks placed in the middle of the storage frame 603 corresponds to the position of the slicing knife 4. The friction wheel 701 at one end of the left take-up shaft 611 and the right take-up shaft 612 will be in close contact with the friction pad 706, which plays a role in limiting and stabilizing the left take-up shaft 611 and the right take-up shaft 612. This makes the left take-up shaft 611 and the right take-up shaft 612 more stable when they are pulled and rotated, and will not cause excessive rotation that would loosen the left traction rope 613 and the right traction rope 614.
[0065] Then, the hydraulic telescopic rod 3 extends downward, driving the slicing blade 4 downward, causing it to detach from the protective cover 5 and slice the stacked blanks inside the storage frame 603 into sheet-like blanks of the same thickness. After slicing, the slicing blade 4 rises, the right winding motor 609 restarts, driving the right winding shaft 612 to rotate, and winding the right traction rope 614 again, thereby pulling the moving plate 602 to move until the next storage frame 603 moves below the slicing blade 4. Correspondingly, the control button 629 below is pressed, activating the laser. The laser emitter 627 is activated, and the laser is captured by the laser receiver 628 to accurately position the storage frame 603. Then, the slicing blade 4 can descend again to slice the stack of blanks below. The blanks that have just been sliced are moved to one side, and the operator can remove them and place new stacks of blanks in the empty storage frame 603. The moving plate 602 moves intermittently a certain distance to cut one stack of blanks in the storage frame 603 at a time. When performing subsequent cuts, the blanks that have been cut can be removed before the stack of blanks can be loaded.
[0066] Then, the last storage box 603 on the moving plate 602 moves to below the slicing blade 4 to slice the stacked blanks. After completion, the right take-up motor 609 starts, pulling the moving plate 602 to one side again. The extrusion rod 605 extrudes and pushes the movable rod 621 above the right take-up shaft 612, causing the contact switch 625 to be extruded. This activates the hydraulic adjustment rod 607 in the corresponding direction, causing it to retract downwards and drive the right take-up motor 609 down, releasing the limit on the right take-up shaft 612. Meanwhile, the corresponding left take-up motor 60... The hydraulic adjustment rod 607 of the 8 extends upward, pushing the left winding motor 608 to rise. The drive gear 610 at its end rises and meshes with the corresponding transmission gear 615. The worker can remove the cut blank from the last storage frame 603 and then take a stack of blanks and place it in the storage frame 603. At this time, all the previous storage frames 603 are also filled with stacks of blanks. The loading and unloading are carried out at the same time. After moving to one side and cutting, the unloading and repositioning of blanks in multiple storage frames 603 are completed in sequence.
[0067] Next, reverse traction operation is implemented. The left winding motor 608 drives the left winding shaft 611 to rotate, and the left traction rope 613 is wound to pull the moving long plate 602 forward. This repeats the intermittent movement of the moving long plate 602, so that multiple storage frames 603 move sequentially to the bottom of the slicing blade 4 for slicing. The stacked embryo material is produced by using a seedling tray stacking machine to heat-melt and stack paper material with hot-melt adhesive properties and low price and biodegradability. The stacked embryo material is cut into sheet embryo material. After the sheet embryo material is removed, it can be sealed with a sheet material bottom sealing machine to form the corresponding paper seedling tray.
[0068] When the left traction rope 613 and right traction rope 614 are pulled, they remain taut, pressing against the edge of the contact wheel 714 and exerting pressure. This causes the contact pad 713 to press tightly against the end of the pressure sensor 717, which senses the pressure. The limiting protrusion 715 limits the left traction rope 613 and right traction rope 614, preventing them from tilting to either side. The pressure sensor 717 monitors the state of the left traction rope 613 and right traction rope 614. If the friction pad 706 remains in close contact with the friction wheel 701, the resulting friction limits and stabilizes the left and right take-up shafts 611 and 612, preventing them from rotating excessively. The left traction rope 613 and right traction rope 614 remain taut. If the friction pad 706 wears down to a certain extent and no longer remains in close contact with the friction wheel 701, it loses its support for the left and right take-up shafts 611 and 612. The limiting position of 2 can easily cause the left traction rope 613 and right traction rope 614 to loosen, affecting subsequent winding and pulling. When loose, the pressing pressure on the bonding wheel 714 decreases, and the pressure sensed by the pressure sensor 717 changes significantly. The staff can maintain the equipment in time. If the friction pad 706 is worn too much, the mounting bolt 704 can be loosened to remove the mounting block 703 and the arc-shaped limiting frame 705. Take out the worn friction pad 706, insert the new friction pad 706 into the arc-shaped limiting frame 705, with one end tightly attached to the limiting arc-shaped block 707. Insert the mounting block 703 into the positioning block 702 and lock it with the mounting bolt 704. The back of the friction pad 706 is tightly attached to the arc-shaped bonding block 708. Both sides of the friction pad 706 are limited, making its installation more stable. After replacement, it is tightly attached to the friction wheel 701. Its friction can be used to stabilize the left winding shaft 611 and right winding shaft 612 again.
[0069] Meanwhile, a new type of rice seedling tray is produced according to a new method for making rice seedling trays.
