[0002] Currently, in the field of tobacco planting technology, chain paper pots are beginning to be used to sow tobacco seedlings, so that tobacco seedlings can be planted continuously without the need for ridges and ponds. However, the chain paper pots currently on the market are mainly formed by pasting two equal-length parallel paper strips at specific positions. A folded seedling hole structure is formed between two adjacent pasting points. The paper strips are folded back and forth at a certain length to form a rectangular chain paper pot. During subsequent use, the user can first unfold the rectangular chain paper pot to unfold the folded seedling holes. After placing the seeds for seedling cultivation, the rectangular chain paper pot can be stretched to form a chain-shaped chain paper pot. However, when this type of chain paper pot is stretched to form a chain shape, multiple seedling holes will be concentrated on a single side of the paper tape, causing the chain paper pot to overturn toward the side where the seedling holes are formed, and it cannot be inserted vertically into the ridge ditch, affecting the planting efficiency.

Then the material moving component drives the flipping component and the suction component to reset and repeat the above steps, so that the suction component sucks the new paper sheet again and sticks the paper sheet to the lower side of the paper tape, thereby forming an unexpanded seedling hole structure on both sides of the paper tape. The paper strip then moves to the drying unit, where the hot press moves toward the base plate to dry the glue and set the seedling holes. Once the holes are set, the strip moves to the folding unit, which folds the strip along the creases to form a folded chain pot. By implementing the adhesive and drying units, the folded seedling holes are formed on both sides of the strip, optimizing the chain pot structure and preventing it from tipping over during subsequent sowing.

[0030] Reference Figures 1 to 5 As shown, a manufacturing device for a seedling hole structure in a chain paper pot provided according to an embodiment of the present application includes: a workbench 100, a crease device 200, a sticker device 300 and a drying device 400, the workbench 100 is provided with a unwinding device 110, three flattening traction roller groups 120 and a folding device in sequence along the first direction, a processing station 130 is formed between two adjacent flattening traction roller groups 120, the unwinding device 110 is wound with a paper tape to be processed, and the paper tape passes through the three flattening traction roller groups 120 and the folding device in sequence.

[0031] The crease device 200 is mounted on the processing station 130 near the unwinding device 110. The crease device 200 includes two opposing crease rollers, with a gap formed between the two rollers for the paper tape to pass through. The two crease rollers cooperate to form creases on the paper tape. Specifically, the outer peripheral walls of the crease rollers are symmetrically provided with protrusions and depressions with triangular cross-sections. The two crease rollers are arranged 180° apart, so that the protrusion of one roller is opposite the depression of the other roller. When the paper tape passes between the protrusion and depression, a crease is formed on the surface of the paper tape. The two crease rollers rotate continuously, forming creases alternately on both sides of the paper tape.

[0032] Along the second direction, the sticker device 300 is located on one side of the workbench 100, and the sticker device 300 is located on the rear side of the crease device 200 in the first direction. The sticker device 300 includes a material storage frame 310, a material moving component 320, a flip component 330, a glue spraying component 340 and a suction component 350. The material storage frame 310 is located on one side of the workbench 100, and paper sheets are stored in the material storage frame 310. The suction component 350 is located above the material storage frame 310. The material moving component 320 includes a first screw drive component, a second screw drive component and a third screw drive component. Rod driving member, the first screw driving member is provided with a first slider capable of reciprocating along the first direction, the second screw driving member is installed on the first slider, the second screw driving member is provided with a second driving member capable of reciprocating along the second direction, the third screw driving member is installed on the second slider, the third screw driving member is provided with a third slider capable of reciprocating along the vertical direction, the flipping assembly 330 includes a motor 331 and a rotating shaft 332, the motor 331 is installed on the third slider, the rotating shaft 332 is rotatably connected to the third slider and is transmission-connected to the output shaft of the motor 331.

[0033] The glue spraying assembly 340 is fixed to the second screw drive member and is located above the suction assembly 350. The rotating shaft 332 of the flipping assembly 330 is connected to the suction assembly 350. The output end of the material moving assembly 320 is connected to the flipping assembly 330. The flipping assembly 330 cooperates with the material moving assembly 320 to drive the suction assembly 350 to move the paper sheet to the glue spraying assembly 340 for the glue spraying assembly 340 to spray glue, or to stick the glued paper sheet to the upper side or the lower side of the paper tape. The drying device 400 is installed on the processing station 130 near the folding device. The drying device 400 includes a base plate 410 and a hot press plate 420. The hot press plate 420 is located above the base plate 410 and can move toward or away from the base plate 410. The folding device can fold the paper tape according to the crease on the paper tape. The first direction, the second direction and the vertical direction are perpendicular to each other.

[0034] It should be noted that the sticker device 300, the drying device 400 and the folding device usually operate synchronously, that is, while the sticker device 300 is stickering, the drying device 400 is drying the already stickered paper sheets, and the folding device folds the dried paper sheets and paper tapes at the same time. When the three flattening traction roller groups 120 are running, the sticker device 300, the drying device 400 and the folding device are stopped synchronously.

[0035] It can be understood that when the manufacturing equipment of the seedling hole structure in the chain paper pot is working, the three flattening traction roller groups 120 are linked together, and the traction paper tape passes through the unwinding device 110, the crease device 200, the sticker device 300, the drying device 400 and the folding device in sequence. The crease device 200 can form creases on the paper tape, and the flattening traction roller group 120 can flatten the paper tape and pull the paper tape to move along the first direction. The material moving component 320 of the sticker device 300 first drives the flipping component 330 to drive the suction component 350 to move to the top of the material storage frame 310 to suck the paper sheet, and the flipping component 330 rotates to cause the suction component 350 to drive the paper sheet to rotate 180 degrees, and the material moving component 320 then drives the flipping component 330 to drive The paper piece moves to the bottom of the glue spraying assembly 340, which sprays two parallel strips of glue on the paper piece. The material moving assembly 320 then drives the flipping assembly 330 to move the glue-sprayed paper piece to the upper side of the paper strip and press the paper piece downward, so that the paper piece is attached to the upper side of the paper strip, forming an unexpanded seedling hole structure. The material moving assembly 320 then drives the flipping assembly 330 and the suction assembly 350 to reset and repeat the above steps, so that the suction assembly 350 picks up a new paper piece and sticks it to the lower side of the paper strip. This process repeats (or the material moving assembly 320 first sticks the paper piece to the upper side of the paper strip, then sticks the paper piece to the lower side of the paper strip, and so on), thereby forming an unexpanded seedling hole structure on both sides of the paper strip. The paper strip then drives the paper piece to the drying device 400. The hot press plate 420 moves toward the bottom plate 410 and dries the glue, so that the seedling hole is fixed. After the seedling hole is shaped, the paper tape moves to the folding device, which folds the paper tape according to the creases to form a folded chain paper pot.

[0036] By setting the sticker device 300 and the drying device 400, a folded seedling hole structure is formed on both sides of the paper tape, the chain paper pot structure is optimized, and it is ensured that the chain paper pot will not overturn during subsequent sowing.

[0037] Furthermore, the flattening traction roller assembly 120 includes two transmission rollers 121, which are arranged opposite each other in a vertical direction and are transmission-connected. The upper transmission roller 121 can move in the vertical direction. Specifically, bearing seats are connected to each end of the transmission roller 121. The bearing seats of both transmission rollers 121 are mounted on the support of the workbench 100. The bearing seat of the upper transmission roller 121 is connected to a vertically arranged screw. The screw rotates in conjunction with the support. The user can vertically move the upper transmission roller 121 by rotating the screw.

[0038] With the above arrangement, the user can adjust the height of the upper transmission roller 121, thereby changing the size of the gap between the two transmission rollers 121, so that the flattening traction roller group 120 can adapt to paper tapes of different thicknesses, or the flattening traction roller group 120 can adapt to paper tapes after pasting paper pieces at different positions, effectively improving the practicality of the flattening traction roller group 120.

[0039] Reference Figures 1 to 3 As shown, it can be understood that a support plate 131 is installed on the processing station 130 near the unwinding device 110, and the support plate 131 is fixed to the workbench 100 through a pillar. The support plate 131 is located on the rear side of the crease device 200 in the first direction, and two support plates 131 are spaced apart along the first direction, one of the support plates 131 is located on the upper side of the paper tape, and the other support plate 131 is located on the lower side of the paper tape.

[0040] By setting up the support plate 131, when the material moving component 320 drives the suction component 350 to press the glue-sprayed paper piece to stick it on the paper tape, the support plate 131 can provide support for the paper tape, disperse the pressure exerted on the paper tape by the suction component 350, and avoid the paper tape from breaking.

[0041] Reference Figure 3 As shown, it can be understood that, along the first direction, two pressing rollers 132 are symmetrically provided on both sides of the support plate 131 , and a gap is formed between the pressing rollers 132 and the support plate 131 for the paper supply belt to pass through.

[0042] By setting a clamping roller 132, the clamping roller 132 and the support plate 131 cooperate to reduce the friction on the paper tape and facilitate the movement of the paper tape, and also limit the paper tape in the vertical direction to avoid the paper tape from deflecting or wrinkling, thereby ensuring the flatness of the paper tape.

[0043] Furthermore, a flexible pad is provided on the side of the support plate 131 facing the paper tape. Optionally, the flexible pad can be made of foam, sponge, rubber and other materials, which will not be described in detail here.

[0044] By providing the flexible pad, when the paper sheet contacts the paper tape, the flexible pad can buffer the impact force exerted by the paper sheet on the paper tape, thereby preventing the paper tape from breaking.

[0045] Reference Figure 1 As shown, it can be understood that two drying devices 400 are provided, and the two drying devices 400 are spaced apart along the first direction, and the distance between the two drying devices 400 is equal to the distance between the two support plates 131.

[0046] By providing two drying devices 400, the two drying devices 400 can simultaneously dry the glue on the paper sheets on both sides of the paper tape, reducing the start and stop times of the unwinding device 110 and the flattening traction roller group 120, and improving the production efficiency of the manufacturing equipment.

[0047] Reference Figure 1 and Figure 4As shown, it can be understood that, along the first direction, tensioning roller groups 500 are provided on both sides of the flattening traction roller group 120 close to the unwinding device 110, and the tensioning roller group 500 includes two tension rollers 510, and the two tension rollers 510 are spaced apart along the first direction and spaced apart along the vertical direction, and the two tension rollers 510 are respectively in contact with both sides of the paper tape.

[0048] By providing the tensioning roller set 500, the two tension rollers 510 of the tensioning roller set 500 can stretch the paper tape so that the paper tape maintains a certain surface tension before and after flattening, thereby further improving the flatness of the paper tape.

[0049] Furthermore, the tensioning roller assembly 500 also includes a retractable roller 520, which is located between the two tension rollers 510 and abuts the paper tape. The retractable roller 520 is capable of vertical movement. Specifically, two support members are provided on the workbench 100 spaced apart along a first direction. The support members include two support columns spaced apart along a second direction. The tensioning roller 510 is correspondingly mounted between the two support columns. A fourth screw drive is mounted between the two support members. The fourth screw drive includes a fourth slider capable of vertical movement. The fourth slider is slidably connected to the four support columns of the two support members. The retractable roller 520 is rotatably mounted on the fourth slider.

[0050] When the unwinding device 110 releases the paper tape, the rewinding roller 520 moves downward, storing a certain length of paper tape between the two tension rollers 510 (the stored length of the paper tape is equal to the distance the rewinding roller 520 has moved downward). The unwinding device 110 then stops, and the rewinding roller 520 moves upward, releasing the temporarily stored paper tape. By providing the rewinding roller 520, the tensioning roller assembly 500 can cache and release the paper tape. The tensioning roller assembly 500 can partially replace the unwinding function of the unwinding device 110, caching some of the paper tape while the sticker device 300, drying device 400, or folding device is operating, and releasing some of the paper tape after the sticker device 300, drying device 400, or folding device completes a process. This reduces the number of starts and stops of the unwinding device 110 and extends its service life.

[0051] Reference Figure 4 As shown, it can be understood that the tensioning roller set 500 further includes two position sensors 530 , and the two position sensors 530 are symmetrically arranged on both sides of the retracting roller 520 along the vertical direction.

[0052] By setting up two position sensors 530, on the one hand, the two position sensors 530 can detect the upper and lower limit positions of the retracting roller 520, and then determine whether the tensioning roller group 500 is in the state of caching the paper tape or releasing the paper tape, ensuring that the subsequent sticker device 300, drying device 400 or folding device starts working only after the tensioning roller group 500 releases the paper tape, ensuring the orderly operation of each device in the manufacturing equipment; on the other hand, when the position sensor 530 detects that the retracting roller 520 is in the limit position, it can feedback to the fourth screw drive component, and then control the fourth slider to stop, so as to avoid the retracting roller 520 being involved in the unreleased paper tape, causing the paper tape to break.

[0053] Reference Figure 5 As shown, it can be understood that the glue spraying assembly 340 is connected to a baffle 341 , and along the second direction, the baffle 341 is located between the workbench 100 and the material storage frame 310 .

[0054] By providing the baffle 341 , when the glue spraying assembly 340 sprays glue toward the paper sheet, the baffle 341 can shield the sprayed glue, preventing the glue from contaminating the material moving assembly 320 or the flipping assembly 330 , thereby effectively improving the structural rationality of the glue spraying assembly 340 .

[0055] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
