[0017] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0018] 1. A two-way traction mechanism is provided, and the left winding motor and the right winding motor are used to run alternately on both sides, respectively, to drive the left winding shaft and the right winding shaft to rotate, and the left traction rope and the right traction rope are wound, and then the moving long board is pulled to move to both sides, and the corresponding storage frame is pushed to the bottom of the slicing tool for slicing, and the seedling tray embryonic material is cut into sheet embryonic material of the same thickness. Multiple storage frames are used, and loading and unloading can be carried out at the same time, and both sides of the slicing tool can be loaded and unloaded. After the cutting is completed in the storage frame, the storage frame is pulled forward, and the staff removes the cut sheet embryonic material and puts the embryonic material to be cut into the storage frame. When the moving long board moves in the opposite direction, the inserted embryonic material can be pulled to the bottom of the slicing tool for cutting. Loading and unloading are carried out in both directions, and the operation is switched according to the moving direction, which effectively improves the work efficiency and reduces the waiting time for the same operation.

[0019] At the same time, the extruded round rod is used to move along with the moving long board. When it moves to the end, the movable rod and the pushing block are squeezed, the extrusion spring is compressed, the pushing block and the contact pad are in contact with the contact switch, and the hydraulic adjustment rod in the corresponding direction is controlled. After the moving long board moves to the end, the operation status of the left winding motor and the right winding motor are alternated, and then the corresponding left winding motor or the right winding motor is lifted and lowered, so that the driving gear on one side can mesh with the transmission gear and then rotate synchronously, and the driving gear on the other side is away from the transmission gear and will not hinder the rotation operation. The control method is simple, and automatic operation and control are performed according to the position of the moving long board.

[0020] 2. The laser receiver corresponds to the laser transmitter moved under the slicing tool, which plays a role in positioning detection. After the laser receiver captures the emitted laser, it responds to the information in time, and then controls the left winding motor and the right winding motor. Then the left winding motor and the right winding motor drive the moving long board to the determined position and then stop, so that the pulling travel position is more accurate;

[0021] At the same time, the hemispherical contact block is squeezed by the arc-shaped metal spring when it moves, so that the buffer pad presses on the control button to start the laser emitter, and then emits laser downward for positioning detection. Only the laser emitter that moves to the corresponding position under the slicing tool will be started, and other laser emitters are in the off state, reducing energy consumption in the idle state and realizing the concept of energy saving and environmental protection in production.

[0022] 3. A monitoring and protection mechanism is provided, which uses the friction wheel and the friction pad to fit each other, and the friction force plays a stabilizing role on the left and right reel shafts, so that the left and right reel shafts can rotate only when they are pulled by the left and right traction ropes, thereby improving their stability and making the rotation angle more accurate, and preventing the left and right reel shafts from shaking when being pulled, causing excessive rotation and loosening of the left and right traction ropes, which will affect the subsequent rotation and pulling operations;

[0023] The friction pad is embedded in the arc-shaped limit frame and is blocked and positioned by the limit arc block. The mounting block is fixed in the positioning block. The installation method is simple. The other side of the friction pad is in contact with the arc-shaped fitting block, so that the friction pad is limited on both sides. The installation is more stable, and the installation and replacement methods are extremely simple.

[0024] 4. Use the fitting wheel to contact the left traction rope and the right traction rope, that is, the left traction rope and the right traction rope squeeze the fitting wheel, and the positioning frame and the fitting pad exert a certain pressure on the pressure sensor, so as to sense that the left traction rope and the right traction rope remain in a straight and tightly compressed state, and then monitor the state of the left traction rope and the right traction rope. When the left traction rope and the right traction rope are loose, the pressure sensed by the pressure sensor changes greatly, and the staff can capture the signal in time to make adjustments, and it plays a monitoring role on the friction pad. When the friction pad continues to wear and cannot continue to fit and rub against the friction wheel, the left traction rope and the right traction rope are prone to loosening, which reminds the staff and makes replacement and adjustment in time.

[0025] To summarize, through the two-way traction mechanism and the monitoring and protection mechanism, in the process of pulling the mobile long board, the left traction rope and the right traction rope are used to pull the mobile long board, and the friction force generated by the friction wheel and the friction pad is to limit the left winding shaft and the right winding shaft, which fully ensures that there will be no problems in winding up the left traction rope and the right traction rope, and the pressure sensor monitors the straightness of the left traction rope and the right traction rope through the sensed pressure, and also maintains the traction condition of the left traction rope and the right traction rope, thereby improving the stability of traction and being able to capture and maintain in time when problems occur.

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 on both sides, and the installation is more stable. The installation and replacement methods are extremely simple.

[0062] A fixed bottom plate 709 is fixedly installed in the middle of one end of the top of the fixed bracket 616, a rotating seat 710 is fixedly installed in the middle of the fixed bottom plate 709, a connecting plate 711 is movably connected to the middle of the rotating seat 710 through a rotating shaft, a positioning frame 712 is fixedly installed on the top of the connecting plate 711, a bonding pad 713 is fixedly bonded to the surface of one end of the positioning frame 712, a bonding wheel 714 is fixedly connected to the other end of the bonding pad 713, and limited position protrusions 715 are symmetrically fixedly installed on both sides of the bonding wheel 714. A mounting vertical plate 716 is fixedly installed at the top of the rotating seat 710, and a pressure sensor 717 is installed at the top of the mounting vertical plate 716. An inclined connecting seat 718 is fixedly installed at one end of the top of the fixed bottom plate 709 away from the mounting vertical plate 716. A buffer spring 719 is fixedly connected to the inclined end of the inclined connecting seat 718. The bonding pad 713 is closely attached to the surface of the pressure sensor 717. The bonding wheel 714 is located below the limiting wheel 618. One end surface of the bonding wheel 714 is connected to the bonding pad 713 and the bonding wheel 718. 14 is in contact with each other, the limiting protrusion 715 is located on both sides of the fitting pad 713 and the fitting wheel 714, the top of the buffer spring 719 is connected to the middle of the connecting plate 711, and the fitting wheel 714 is used to contact 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 fitting wheel 714, and the positioning frame 712 and the fitting 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 kept straight and tightly pressed, 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 are loose, the pressure sensed by the pressure sensor 717 changes greatly. The staff can capture the signal in time to make adjustments, and the friction pad 706 is monitored. When the friction pad 706 is continuously worn and can no longer fit and rub against the friction wheel 701, the left traction rope 613 and the right traction rope 614 are prone to loosening, which reminds the staff and allows timely replacement and adjustment.

[0063] The working principle and use process of the present invention are as follows: first, a hydraulic adjustment rod 607 contracts downward, pulling the right winding motor 609 and the driving gear 610 to move downward, so that the corresponding driving gear 610 is away from the transmission gear 615, and then the right winding shaft 612 loses its limit, and the driving gear 610 corresponding to the left winding motor 608 is meshed with the transmission gear 615 at the end of the left winding shaft 611, and the left winding motor 608 is used to drive the driving gear 610 and the transmission gear 615 to rotate, and the left winding shaft 611 reels the left traction rope 613, pulling the movable long board 602 to move to the frame 1. At one end, one end of the movable long plate 602 is located above the left winding shaft 611, the squeezing round rod 605 squeezes the movable rod 621, the squeezing spring 622 is compressed, the pushing block 623 moves forward with the movable rod 621, the contact pad 624 presses on the surface of the contact switch 625, and the contact switch 625 transmits a signal to the hydraulic adjustment rod 607, the hydraulic adjustment rod 607 contracts downward, driving the left winding motor 608 to descend, and the hydraulic adjustment rod 607 on the other side extends, driving the right winding motor 609 to rise, and the driving gear 610 at its end is meshed with the corresponding transmission gear 615 above;

[0064] At this time, the staff puts the prepared seedling tray stack-shaped embryo materials in the storage frame 603 in turn, and the right winding motor 609 is started, driving the driving gear 610 to rotate continuously, so that it meshes with the transmission gear 615, and then drives the right winding shaft 612 to rotate, and the right traction rope 614 is wound, and the moving long plate 602 is pulled to move along the guide groove 601. After moving a certain distance, a storage frame 603 moves to the bottom of the slicing tool 4, and the mounting seat 626 under this storage frame 603 corresponds to the position of the laser receiver 628, and the corresponding hemispherical contact block 633 at one end contacts with the arc-shaped metal spring piece 635, and is squeezed by the arc-shaped metal spring piece 635, and the movable plate 631 moves along the guide rod 630 The buffer pad 632 squeezes the control button 629, starts the corresponding laser transmitter 627, and emits laser downward until the emitted laser is captured by the laser receiver 628, transmits the signal, and the right winding motor 609 stops rotating, indicating that the stack-shaped blank placed in the middle of the storage frame 603 corresponds to the position of the slicing tool 4, and the friction wheel 701 at one end of the left winding shaft 611 and the right winding shaft 612 will be in close contact with the friction pad 706, which plays a role in limiting and stabilizing the left winding shaft 611 and the right winding shaft 612, so that the left winding shaft 611 and the right winding shaft 612 are more stable when being pulled and rotated, and there will be no excessive rotation to cause the left traction rope 613 and the right traction rope 614 to loosen;

[0065] Then, the hydraulic telescopic rod 3 extends downward, driving the slicing tool 4 to move downward, so that the slicing tool 4 is separated from the protective cover 5, and slices the stack-shaped blank inside the storage frame 603 downward to cut it into sheet blanks of the same thickness. After the cutting is completed, the slicing tool 4 rises, and the right winding motor 609 is started again, driving the right winding shaft 612 to rotate, and winding the right traction rope 614 again, thereby pulling the moving long board 602 to move, until the next storage frame 603 moves to the bottom of the slicing tool 4, and accordingly, the control button 629 below is pressed to activate the laser emitter. The emitter 627 is started, and the laser is captured by the laser receiver 628, and the position of the storage frame 603 is accurately located. Then the slicing tool 4 can be lowered again to slice the stack-shaped blank below, and the blank just sliced ​​is moved to one side, and the staff can take it off, and put the new stack-shaped blank in the vacant storage frame 603. The moving long board 602 moves a certain distance intermittently, and cuts a stack-shaped blank in the storage frame 603 each time. When performing subsequent cutting, the blank after cutting can be taken off, and then the stack-shaped blank loading operation is performed;

[0066] Then, the last storage frame 603 on the mobile long board 602 moves to the bottom of the slicing tool 4 to slice the stacked blank. After completion, the right winding motor 609 is started to pull the mobile long board 602 to one side again, and the squeezing round rod 605 squeezes and pushes the movable rod 621 above the right winding shaft 612, so that the contact switch 625 is squeezed, and the hydraulic adjustment rod 607 in the corresponding direction is started and retracted downward, driving the right winding motor 609 to descend, releasing the limit of the right winding shaft 612, and the corresponding left winding motor 60 The hydraulic adjustment rod 607 of 8 extends upward, pushing the left winding motor 608 to rise, and the driving gear 610 at its end rises and meshes with the corresponding transmission gear 615. The staff can take down the cut blank on the last storage frame 603, and then take out a stack-shaped blank and place it in the storage frame 603. At this time, all the previous storage frames 603 are also filled with stack-shaped blanks. The unloading and loading are carried out at the same time. After moving to one side and cutting is completed, the unloading and re-placing operations in multiple storage frames 603 are completed in sequence.

[0067] Next, the reverse traction operation is realized, 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 board 602 to move forward, and then the intermittent movement of the moving long board 602 is repeated, so that the multiple storage frames 603 are moved to the bottom of the slicing tool 4 in turn for slicing processing, and the stack-shaped blank material is obtained by using a seedling tray stacking machine to heat-melt and stack the paper material with hot-melt adhesive performance, low price and degradable, and the stack-shaped blank material is cut into sheet blank material, and after the sheet blank material is removed, the sheet material bottom sealing machine can be used for bottom sealing processing, thereby forming a corresponding paper seedling tray;

[0068] When the left and right traction ropes 613 and 614 are pulled, they remain in a taut state, and they are squeezed on the edge of the fitting wheel 714, exerting a certain pressure on it, so that the fitting pad 713 is pressed tightly against the end of the pressure sensor 717, which will sense a certain pressure. The limiting protrusion 715 limits the left and right traction ropes 613 and 614, so that they will not tilt to both sides. The pressure sensor 717 can be used to monitor the status of the left and right traction ropes 613 and 614. If the friction pad 706 is always in close contact with the friction wheel 701, the friction force generated will limit and stabilize the left and right winding shafts 611 and 612, so that they will not rotate too much easily. The left and right traction ropes 613 and 614 continue to remain taut. If the friction pad 706 is worn to a certain extent, it will no longer be in close contact with the friction wheel 701, that is, it will lose the left and right winding shafts 611 and 612. 2, it is easy to cause the left traction rope 613 and the right traction rope 614 to loosen, affecting the subsequent winding and pulling. When loose, the pressing force on the fitting wheel 714 is reduced, and the pressure sensed by the pressure sensor 717 changes greatly. The staff can maintain the equipment in time. The friction pad 706 is worn too much, and the mounting bolt 704 can be screwed, the mounting block 703 and the arc limit frame 705 can be removed, the worn friction pad 706 can be taken out, and a new friction pad 706 can be inserted into the arc limit frame 705, one end of which is tightly against the limiting arc block 707, the mounting block 703 is inserted into the positioning block 702, and locked with the mounting bolt 704, the back of the friction pad 706 is tightly against the arc fitting block 708, and both sides of the friction pad 706 are limited, making its installation more stable. After replacement, it is tightly against the friction wheel 701, and its friction force can be used to stabilize the left and right winding shafts 611 and 612 again.
