Description

Technical Field

[0001] This utility model relates to the technical field of chain-type paper pot production equipment, and in particular to a manufacturing equipment for the seedling hole structure in a chain-type paper pot. Background Technology

[0002] Currently, in tobacco cultivation technology, chain-type paper pots are being used to sow tobacco seedlings, enabling continuous planting without the need for ridging or furrowing. However, most chain-type paper pots on the market consist of two parallel paper strips of equal length glued together at specific locations. Folded seedling holes are formed between adjacent glued points. The paper strips are folded back and forth along a certain length to form a rectangular chain-type paper pot. For subsequent use, the user can first unfold the rectangular chain-type paper pot, opening the folded seedling holes. After placing the seeds in for seedling cultivation, the rectangular chain-type paper pot can be stretched to form a chain-like structure. However, when this type of chain-type paper pot is stretched into a chain shape, multiple seedling holes tend to concentrate on one side of the paper strip, causing the chain-type paper pot to tilt towards the side with the seedling holes, making it impossible to insert vertically into the furrow and affecting planting efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a manufacturing device for the seedling hole structure in a chain-type paper pot, which forms the seedling hole structure on both sides of the paper strip, optimizes the structure, and prevents the chain-type paper pot from tipping over.

[0004] To achieve this objective, the present invention adopts the following technical solution: A manufacturing device for the seedling hole structure in a chain-type paper tray, comprising: a workbench, a crease device, a paper pasting device, and a drying device. The workbench is sequentially equipped with an unwinding device, three flattening traction roller groups, and a folding device along a first direction. A processing station is formed between two adjacent flattening traction roller groups. The unwinding device winds a paper strip to be processed, and the paper strip passes sequentially through the three flattening traction roller groups and the folding device. The crease device is installed at the processing station near the unwinding device. The crease device includes two opposing crease pressure rollers, with a gap between the two crease pressure rollers for the paper strip to pass through. The two crease pressure rollers cooperate to generate creases on the paper strip. The paper pasting device is located on one side of the workbench and at the location of the crease device in the first direction. On one side, the sticker-applying device includes a storage box, a transfer component, a flipping component, a glue spraying component, and a suction component. The storage box stores paper pieces. The suction component is located above the storage box, and the glue spraying component is located above the suction component. The flipping component is connected to the suction component, and the output end of the transfer component is connected to the flipping component. The flipping component cooperates with the transfer component to drive the suction component to move the paper pieces to the glue spraying component for glue spraying, or to stick the glued paper pieces to the upper or lower side of the paper strip. A drying device is installed at the processing station near the folding device. The drying device includes a base plate and a hot press plate. The hot press plate is located above the base plate and can move towards or away from the base plate.

[0005] Preferably, a support plate is installed at the processing station near the unwinding device. The support plate is located on the rear side of the crease device in the first direction. Two support plates are spaced apart along the first direction, one of which is located on the upper side of the paper tape and the other is located on the lower side of the paper tape.

[0006] Preferably, along the first direction, two clamping rollers are symmetrically arranged on both sides of the support plate, and a gap is formed between the clamping rollers and the support plate for the paper strip to pass through.

[0007] Preferably, the support plate has a flexible pad on the side facing the paper tape.

[0008] Preferably, there are two drying devices, which are spaced apart along a first direction, and the distance between the two drying devices is equal to the distance between the two support plates.

[0009] Preferably, tension roller groups are provided on both sides of the flattening traction roller group near the unwinding device along the first direction. The tension roller group includes two tension rollers, which are spaced apart along the first direction and spaced apart along the vertical direction. The two tension rollers respectively abut against both sides of the paper tape.

[0010] Preferably, the tension roller assembly further includes a take-up and release roller, which is located between the two tension rollers and abuts against the paper strip, and the take-up and release roller is movable in the vertical direction.

[0011] Preferably, the tensioning roller assembly further includes two position sensors, which are symmetrically arranged on both sides of the take-up and release rollers along the vertical direction.

[0012] Preferably, the flattening traction roller group includes two drive rollers, which are arranged opposite each other in the vertical direction and connected by transmission, and the drive roller located at the top can move in the vertical direction.

[0013] Preferably, the adhesive spraying assembly is connected to a baffle, which is located between the workbench and the storage box.

[0014] The beneficial effects of this utility model: When the equipment for manufacturing the seedling hole structure in the chain-type paper pot is working, three flattening traction roller groups work together to pull the paper belt through the unwinding device, crease device, sticker device, drying device and finally the folding device. The crease device can form creases on the paper belt. The transfer component of the sticker device first causes the flipping component to move the suction component to the top of the storage frame to pick up the paper sheet. The flipping component rotates to make the suction component rotate the paper sheet 180°. The transfer component then drives the flipping component to move the paper sheet to the bottom of the glue spraying component. The glue spraying component sprays two parallel glue strips on the paper sheet. The transfer component then drives the flipping component to move the glued paper sheet to the top of the paper belt and presses it down, so that the paper sheet is pasted to the top of the paper belt, forming an undeveloped seedling hole structure. Then the transfer component drives the flipping component and suction component to reset and repeat the above steps, so that the suction component picks up a new paper sheet again and pastes the paper sheet to the bottom of the paper belt, thereby forming an undeveloped seedling hole structure on both sides of the paper belt. Next, the paper strip moves the paper sheet to the drying device, where the hot press plate moves towards the base plate and dries the glue, shaping the seedling holes. After the seedling holes are shaped, the paper strip moves to the folding device, which folds the paper strip according to the creases to form a folded chain-type paper pot. By setting up the paper strip pasting device and the drying device, the folded seedling hole structure is formed on both sides of the paper strip, optimizing the chain-type paper pot structure and ensuring that the chain-type paper pot will not tip over during subsequent sowing.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

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

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

[0032] Along the second direction, the sticker applicator 300 is located on one side of the workbench 100, and is located behind the crease applicator 200 in the first direction. The sticker applicator 300 includes a storage box 310, a transfer assembly 320, a flipping assembly 330, a glue spraying assembly 340, and a suction assembly 350. The storage box 310 is located on one side of the workbench 100 and stores paper sheets inside. The suction assembly 350 is located above the storage box 310. The transfer assembly 320 includes a first lead screw drive, a second lead screw drive, and a third lead screw drive. The lever drive includes a first lead screw drive with a first slider capable of reciprocating along a first direction, a second lead screw drive mounted on the first slider with a second drive capable of reciprocating along a second direction, a third lead screw drive mounted on the second slider with a third slider capable of reciprocating along a vertical direction, and a flipping assembly 330 including a motor 331 and a rotating shaft 332. The motor 331 is mounted on the third slider, and the rotating shaft 332 is rotatably connected to the third slider and drively connected to the output shaft of the motor 331.

[0033] The glue spraying assembly 340 is fixed to the second lead screw drive and 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 transfer assembly 320 is connected to the flipping assembly 330. The flipping assembly 330 and the transfer assembly 320 cooperate to drive the suction assembly 350 to move the paper sheet to the glue spraying assembly 340 for glue spraying, or to paste the glued paper sheet to the upper or 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 towards or away from the base plate 410. The folding device can fold the paper tape according to the creases 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 applicator 300, the drying applicator 400, and the folding applicator usually operate synchronously. That is, while the sticker applicator 300 is applying stickers, the drying applicator 400 dries the already applied paper, and the folding applicator folds the dried paper and paper strip at the same time. When the three flattening traction roller groups 120 are running, the sticker applicator 300, the drying applicator 400, and the folding applicator stop synchronously.

[0035] Understandably, when the equipment for manufacturing the seedling hole structure in the chain-type paper pot is working, the three flattening traction roller groups 120 are linked together, pulling the paper strip sequentially through the unwinding device 110, the crease device 200, the paper pasting device 300, the drying device 400, and finally the folding device. The crease device 200 can form creases on the paper strip, and the flattening traction roller group 120 can flatten the paper strip and pull the paper strip to move along the first direction. The material transfer component 320 of the paper pasting device 300 first causes the flipping component 330 to drive the suction component 350 to move above the storage frame 310 to pick up the paper sheet. The flipping component 330 rotates, causing the suction component 350 to drive the paper sheet to rotate 180°. The material transfer component 320 then drives the flipping component 330 to rotate the paper sheet. The paper sheet moves below the glue spraying assembly 340, which sprays two parallel strips of glue onto the paper sheet. The transfer assembly 320 then drives the flipping assembly 330 to move the glued paper sheet to the upper side of the paper belt and presses it down, causing the paper sheet to adhere to the upper side of the paper belt, forming an undeveloped seedling hole structure. Next, the transfer assembly 320 drives the flipping assembly 330 and the suction assembly 350 to reset and repeat the above steps, causing the suction assembly 350 to pick up a new paper sheet again and adhere it to the lower side of the paper belt. This process is repeated (or the transfer assembly 320 first adheres the paper sheet to the upper side of the paper belt, and then adheres it to the lower side of the paper belt, and so on), thereby forming an undeveloped seedling hole structure on both sides of the paper belt. Then, the paper belt carries the paper sheet to the drying device 400, where the hot press plate 420 moves toward the base plate 410 and dries the glue, setting the seedling holes. After the seedling hole is shaped, the paper strip moves to the folding device, which folds the paper strip according to the creases to form a folded chain paper bowl.

[0036] By setting up a sticker-sticking device 300 and a drying device 400, folded seedling hole structures are formed on both sides of the paper strip, optimizing the chain-type paper pot structure and ensuring that the chain-type paper pot will not tip over during subsequent sowing.

[0037] Furthermore, the flattening traction roller assembly 120 includes two drive rollers 121, which are vertically opposite to each other and connected by transmission. The upper drive roller 121 can move vertically. Specifically, each end of the drive roller 121 is connected to a bearing housing, and the bearing housings of both drive rollers 121 are mounted on the support of the worktable 100. The bearing housing of the upper drive roller 121 is connected to a vertically arranged screw, which is rotatably engaged with the support. The user can move the upper drive roller 121 vertically by rotating the screw.

[0038] With the above arrangement, the user can adjust the height of the upper drive roller 121, thereby changing the gap between the two drive rollers 121, so that the flattening traction roller group 120 can adapt to paper tapes of different thicknesses, or adapt the flattening traction roller group 120 to paper tapes after pasting paper pieces in 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. The support plate 131 is fixed to the worktable 100 by a support column. The support plate 131 is located on the rear side of the crease device 200 in the first direction. Two support plates 131 are provided at intervals along the first direction. One support plate 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 the support plate 131, when the transfer component 320 drives the suction component 350 to press the paper sheet after spraying glue onto 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 prevent the paper tape from breaking.

[0041] Reference Figure 3 As shown, it can be understood that, along the first direction, two pressure rollers 132 are symmetrically arranged on both sides of the support plate 131, and a gap is formed between the pressure rollers 132 and the support plate 131 through which the paper feed belt passes.

[0042] By setting up the pressure roller 132, which works in conjunction with the support plate 131, the friction on the paper tape can be reduced, making the paper tape easier to move. It can also limit the paper tape in the vertical direction, preventing the paper tape from shifting or wrinkling, and 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 materials such as foam, sponge, or rubber, which will not be described in detail here.

[0044] By setting up a flexible pad, when the paper comes into contact with the paper tape, the flexible pad can buffer the impact force of the paper on the paper tape and prevent the paper tape from breaking.

[0045] Reference Figure 1 As shown, it can be understood that there are two drying devices 400, which 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 setting up two drying devices 400, the two drying devices 400 can simultaneously dry the glue on the paper sheets on both sides of the paper strip, reducing the number of start-stop cycles 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 tension roller groups 500 are provided on both sides of the flattening traction roller group 120 near the unwinding device 110 along the first direction. The tension roller group 500 includes two tension rollers 510. The two tension rollers 510 are spaced apart along the first direction and spaced apart along the vertical direction. The two tension rollers 510 respectively abut against both sides of the paper tape.

[0048] By setting up the tension roller group 500, the two tension rollers 510 of the tension roller group 500 can stretch the paper strip, so that the paper strip maintains a certain surface tension before and after flattening, thereby further improving the flatness of the paper strip.

[0049] Furthermore, the tension roller assembly 500 also includes a take-up and release roller 520, which is located between the two tension rollers 510 and abuts against the paper tape. The take-up and release roller 520 is movable in the vertical direction. Specifically, two support members are spaced apart along a first direction on the worktable 100. Each support member includes two support columns spaced apart along a second direction. The tension roller 510 is correspondingly installed between the two support columns. A fourth lead screw drive member is installed between the two support members. The fourth lead screw drive member has a fourth slider that is movable in the vertical direction. The fourth slider is slidably connected to the four support columns of the two support members. The take-up and release roller 520 is rotatably mounted on the fourth slider.

[0050] The unwinding device 110 releases the paper tape, and the take-up / unwind roller 520 moves downward, storing a certain length of paper tape between the two tension rollers 510 (the stored paper tape length is equal to the downward movement distance of the take-up / unwind roller 520). Then, the unwinding device 110 stops, and the take-up / unwind roller 520 moves upward, releasing the temporarily stored paper tape. By setting the take-up / unwind roller 520, the tension roller group 500 can buffer and release the paper tape. The tension roller group 500 can replace part of the unwinding function of the unwinding device 110, buffering part of the paper tape when the sticker device 300, drying device 400, or folding device is working, and releasing part of the paper tape after the sticker device 300, drying device 400, or folding device completes one process, reducing the number of starts and stops of the unwinding device 110 and extending its service life.

[0051] Reference Figure 4 As shown, it can be understood that the tensioning roller assembly 500 also includes two position sensors 530, which are symmetrically arranged on both sides of the take-up and release rollers 520 in the vertical direction.

[0052] By setting two position sensors 530, on the one hand, the two position sensors 530 can detect the upper and lower limit positions of the take-up and untake-up rollers 520, and thus determine whether the tension roller group 500 is in the state of buffering paper tape or releasing paper tape, ensuring that the subsequent sticker device 300, drying device 400 or folding device only starts working after the tension 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 take-up and untake-up rollers 520 are in the limit position, it can provide feedback to the fourth lead screw drive, thereby controlling the fourth slider to stop, avoiding the take-up and untake-up rollers 520 from pulling on the unreleased paper tape, which could cause 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, which is located between the worktable 100 and the storage box 310 along the second direction.

[0054] By setting up a baffle 341, when the glue spraying assembly 340 sprays glue onto the paper, the baffle 341 can block the sprayed glue, preventing the glue from contaminating the transfer assembly 320 or the flipping assembly 330, effectively improving the structural rationality of the glue spraying assembly 340.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
