Description

Technical Field

[0001] The present invention relates to the technical field of flue-cured tobacco planting, and in particular to a method for manufacturing a chain paper pot and the chain paper pot. Background Art

[0002] Taking Chuxiong, Yunnan, as an example, in the fragmented tobacco growing areas, tobacco transplanting is still mainly done manually, supplemented by small semi-automatic transplanting machines, due to the wide distribution of available areas, small individual areas, and inconvenient transportation between areas. The efficiency of transplanting is low, and it is difficult to achieve efficient transplanting with large transplanting machines. Furthermore, the operation of semi-automatic transplanting machines requires a large number of personnel to manually feed the tobacco seedlings into the semi-automatic transplanting machines one by one. Long operation times cause fatigue and often lead to seedling leakage. Furthermore, due to the limitations of human physiological reaction speed, the transplanting speed is low, only about 1 plant per second, which is only 2-5 times that of manual planting. This seriously restricts the promotion and application of transplanting machines and increases the burden of transplanting tobacco seedlings.

[0003] Chain paper pots are seeding containers that improve the performance of semi-automatic transplanting machinery. Existing chain paper pots can be used to grow crops such as vegetables and flowers. To meet the spacing requirements for flue-cured tobacco, the spacing between individual pots on existing chain paper pots needs to be increased. However, this makes the chain paper pots difficult to fold, resulting in a larger volume when folded and a tendency for seedlings to fall over during transplanting.

[0004] Based on the above, there is an urgent need for a chain paper bowl manufacturing method and a chain paper bowl to solve the above technical problems. Summary of the Invention

[0005] An object of the present invention is to provide a chain-type paper pot manufacturing method, which can tightly fold multiple individual paper pots suitable for flue-cured tobacco and reduce the phenomenon of seedlings falling over during the transplanting process.

[0006] To achieve this object, the present invention adopts the following technical solutions:

[0007] A chain paper bowl manufacturing method comprising:

[0008] S10, adhering a plurality of paper sheets to a paper tape at intervals, wherein a single paper bowl is formed between each of the paper sheets and the paper tape;

[0009] S20. Fold the paper strip between two adjacent single paper bowls 2n times, wherein the nth and n+1th folds are performed in the same direction, and the spacing between the creases formed by the nth and n+1th folds is twice the length h of the paper sheet, and the remaining two adjacent folds are folded in opposite directions, and the spacing between the creases formed is one times the length h of the paper sheet, to form a paper bowl combination; the paper bowl combination includes at least two single paper bowls, and both sides of each single paper bowl are folded at least n times and bonded together, and the paper sheets in the paper bowl combination are all arranged parallel to a preset first direction.

[0010] Preferably, after step S20, the method further includes:

[0011] S30, arranging the two paper bowl assemblies along a preset second direction, wherein the preset second direction is perpendicular to the preset first direction, and fixedly connecting one end of the paper tapes in two adjacent paper bowl assemblies.

[0012] Preferably, after step S20, the method further includes:

[0013] S31. Arrange at least three paper pot assemblies along a preset second direction, wherein the preset second direction is perpendicular to the preset first direction, and fix the paper strips in at least three adjacent paper pot assemblies in an S-shape or an inverted S-shape.

[0014] Preferably, in step S31, the method further includes:

[0015] Along the preset first direction, two adjacent rows of the paper pot combinations are staggered, the staggered distance is 0.5 times the length h of the paper sheet, and the setting directions of the two adjacent staggered arrangements are opposite.

[0016] Preferably, after step S20 and before step S31, the method further includes:

[0017] S21. An extension area is provided at the end of the paper tape of each paper bowl combination, wherein the length of the extension area is not less than 0.5 times the length h of the paper sheet, and the extension area is used to fixedly connect the paper tapes of two adjacent paper bowl combinations.

[0018] Preferably, in step S10, the method further includes:

[0019] At least two groups of paper sheets are bonded to the paper tape, each group of paper sheets includes m paper sheets, and a first spacing k1 between the m paper sheets in each group of paper sheets satisfies:

[0020] k1=2nh, h is the length of the paper;

[0021] Furthermore, the second spacing k2 between two adjacent groups of paper sheets satisfies:

[0022] k2=(2n+0.5)h.

[0023] Preferably, step S20 further includes:

[0024] The paper strips to which each group of paper sheets is bonded are folded to form a paper bowl assembly.

[0025] Preferably, each group of paper sheets includes 5 paper sheets, and the length of the paper sheets is 6.6 cm.

[0026] The beneficial effects of the chain-type paper bowl manufacturing method of the present invention are as follows:

[0027] This chain paper pot manufacturing method can produce chain paper pots suitable for crops with large planting distances, such as flue-cured tobacco. While achieving large planting distances, a special folding method conceals the longer paper strips between the two individual paper pots, allowing the chain paper pots to be stored and used for seedling cultivation in a smaller volume, significantly reducing transportation, storage, and seedling cultivation costs. Furthermore, this even-numbered folding method primarily utilizes a reciprocating folding strategy, placing folds in the same direction away from the individual paper pots. This allows the chain paper pots to be dragged more smoothly during transfer, reducing problems such as seedling tipping and jamming.

[0028] Another object of the present invention is to provide a chain-type paper pot that is suitable for transferring flue-cured tobacco and reduces the phenomenon of seedlings falling over during the transplanting process.

[0031] The beneficial effects of the chain paper bowl of the present invention are:

[0032] This chain paper pot is suitable for crops with large planting distances, such as flue-cured tobacco. While achieving this large planting distance, the special folding structure conceals the longer paper strips between the two individual pots, allowing the chain paper pots to be stored and used for seedling cultivation in a compact volume, significantly reducing transportation, storage, and seedling cultivation costs. Furthermore, this folding structure primarily utilizes a reciprocating folding strategy, with the folds in the same direction positioned away from the individual pots. This allows the chain paper pots to be dragged more smoothly during transfer, reducing problems such as seedling tipping and jamming. BRIEF DESCRIPTION OF THE DRAWINGS

These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0050] The following is based on the attached Figure 1 To the attached Figure 10 The present invention introduces the chain paper bowl manufacturing method and the chain paper bowl. It should be noted that, in order to facilitate the description of the size, the width direction of the chain paper bowl and the paper belt 1 and paper sheet 2 therein is defined as the same direction (i.e. Figure 1 The vertical direction in the chain paper bowl is defined as the same direction (i.e. Figure 1 horizontal direction in the .

[0051] The chain-type paper bowl manufacturing method comprises:

[0052] S10 , bonding a plurality of paper sheets 2 to the paper tape 1 at intervals, so that a single paper bowl 100 is formed between each of the paper sheets 2 and the paper tape 1 .

[0053] Specifically, in step S10, Figure 1 、 Figure 2As shown, multiple paper pieces 2 are glued to a paper strip 1 at predetermined intervals. The paper strip 1 is a long strip of paper with equal width. Seedling holes are provided at intervals on the long strip of paper 1. Each seedling hole can be glued to a paper piece 2. At the same time, along the length of the paper strip 1, both ends of each seedling hole are glued to the paper piece 2, while the middle part of each seedling hole can be freely separated from the paper piece 2, thereby forming a cavity. Figure 3 As shown, each cavity can form a single paper pot 100 , and after the cavity is filled with a matrix, the flue-cured tobacco seedlings can be grown in the single paper pot 100 .

[0054] After step S10, a chain paper pot in the form of a paper chain can be formed. Then, in order to facilitate seedling cultivation, refer to Figure 4 As shown, it is also necessary to fold and fix the chain pots 100, and reduce the distance between the two individual pots 100 so that the distance between the two adjacent individual pots 100 is significantly smaller than the length of the paper strips 1 of the two individual pots 100, thereby reducing the occupied area during seedling cultivation. Therefore, step S20 is also required as follows:

[0055] S20. Fold the paper strip 1 between two adjacent single paper bowls 100 2n times, wherein the nth and n+1th folds are performed in the same direction, and the distance between the creases formed by the nth and n+1th folds is twice the length h of the paper sheet 2. The remaining two adjacent folds are folded in opposite directions, and the distance between the creases formed is one times the length h of the paper sheet 2, to form a paper bowl combination; the paper bowl combination includes at least two single paper bowls 100, and both sides of each single paper bowl 100 are folded at least n times and bonded together, and the paper sheets 2 in the paper bowl combination are all arranged parallel to the preset first direction.

[0056] For example, Figure 5 As shown, three individual paper bowls 100 (the circle symbol in the figure represents a single paper bowl 100) are arranged in a row to form a paper bowl assembly. In this paper bowl assembly, eight folds are performed between each adjacent paper bowl. The first, second, third, and fourth folds are performed in opposite directions, i.e., a reciprocating fold. The fifth, sixth, seventh, and eighth folds are also performed in opposite directions, i.e., a reciprocating fold. The fourth and fifth folds are folded in the same direction.

[0057] For example, Figure 5As shown, the eight folds form creases A1, A2, A3, A4, A5, A6, A7, and A8. The direction from the individual paper bowl 100 through A1 to A2 is considered the continuation direction of the paper strip 1. The fold direction at A1 can be defined as a clockwise fold, while the fold direction at A2 is the opposite of the fold direction at A2 and can be defined as a counterclockwise fold. Similarly, the fold directions at A3, A6, and A8 are all clockwise, while the fold directions at A4, A5, and A7 are all counterclockwise.

[0058] Furthermore, in order to achieve the effect of hiding the paper tape 1 by attaching the folded paper tape 1 to the side of the paper bowl, continue to refer to Figure 5 As shown, the spacing between A1 and A2, between A2 and A3, between A3 and A4, between A5 and A6, between A6 and A7, and between A7 and A8 is approximately one time the length h of the paper sheet 2, while the spacing between A4 and A5 is approximately two times the length h of the paper sheet 2. That is, the spacing from A1 to A8 is approximately eight times the length h of the paper sheet 2. For example, in this embodiment, the length h of the paper sheet 2 is approximately 6.6 cm, the spacing between A1 and A2 is approximately 6.6 cm, the spacing between A4 and A5 is approximately 13 cm, and the spacing between A1 and A8 is approximately 52.8 cm.

[0059] After folding, the folded paper strip 1 can be fixed in the form of a paper book by gluing and fixing, ensuring that it will not spread out during transportation and seedling cultivation. For example, water-soluble glue is used for gluing, so that after seedling cultivation, the paper strips 1 that are glued and fixed can automatically spread out due to the dissolution of the glue, making it convenient for transfer. At this time, the paper pieces 2 in the paper pot combination are all arranged parallel to the preset first direction, and the folded paper strip 1 is also divided into multiple sections and all arranged parallel to the preset first direction, which can not only make multiple individual paper pots 100 arranged in a regular manner, but also effectively reduce the size of each paper pot combination.

[0060] It should be noted that the value of n and the length h of the paper sheet 2 are determined according to the specific planting requirements of the crop, and in order to ensure smoothness after folding, the present invention does not make detailed requirements on the value of n and the specific numerical value of the length h of the paper sheet 2. In addition, since the specific planting requirements of the crop do not require precise numerical values, the spacing between the above-mentioned folds is approximately one times the length h of the paper sheet 2, and specifically can be between 0.8 times and 1.2 times the length h of the paper sheet 2. The spacing between the above-mentioned folds is approximately twice the length h of the paper sheet 2, and specifically can be between 1.7 times and 2.3 times the length h of the paper sheet 2. As long as the paper strip 1 can be hidden so that the distance between two adjacent individual paper pots 100 is significantly smaller than the length of the paper strip 1 of the two individual paper pots 100, thereby reducing the occupied area during seedling cultivation, then it falls within the scope of protection of the present invention.

[0061] This chain paper pot manufacturing method can produce chain paper pots suitable for crops with large planting distances, such as flue-cured tobacco. While achieving large planting distances, the longer paper strip 1 between the two individual paper pots 100 can be hidden through a special folding method, allowing the chain paper pots to be stored and raised in a smaller volume, significantly reducing transportation, storage, and seedling raising costs. Furthermore, this even-numbered folding method primarily employs a reciprocating folding strategy, placing folds in the same direction away from the individual paper pots 100. This allows the chain paper pots to be dragged more smoothly during transfer, reducing phenomena such as seedling tipping and jamming.

[0062] Preferably, in step S1, the seedling hole area includes a first seedling hole area 11 and multiple second seedling hole areas 12, the first seedling hole area 11 is arranged on one side of the thickness direction of the paper tape 1, and the second seedling hole area 12 is arranged on the other side of the thickness direction of the paper tape 1, so that the single paper pots 100 are alternately formed on both sides of the thickness direction of the paper tape 1, so that in the process of using the chain paper pot, the two sides of the paper tape 1 can be relatively balanced in force, thereby greatly reducing the possibility of the chain paper pot tipping over during use, ensuring that the crop seedlings can maintain a vertical posture during transplanting and planting, and ensuring good growth of the crops.

[0063] Optionally, in some embodiments, after step S20, the method further includes:

[0064] S30, arranging two paper pot assemblies along a preset second direction, wherein the preset second direction is perpendicular to the preset first direction, and fixing one end of the paper tapes 1 in two adjacent paper pot assemblies together.

[0065] Specifically, in step S30, the paper pot assembly is moved along the preset second direction (ie Figure 5 The vertical direction in the figure is arranged to form the following Figure 6Of course, in order to enable the individual paper pots 100 in the two paper pot assemblies to be transferred in sequence, one end of the paper strips 1 in the two adjacent paper pot assemblies needs to be fixedly connected.

[0066] Optionally, in some embodiments, after step S20, the method further includes:

[0067] S31. Arrange at least three paper pot assemblies along a preset second direction, wherein the preset second direction is perpendicular to the preset first direction, and fix the paper strips 1 in the at least three adjacent paper pot assemblies in an S shape or an inverted S shape.

[0068] Specifically, in step S31, Figure 5 、 Figure 7 As shown, place the three paper bowls together along Figure 5 The three paper pots are arranged in the vertical direction, and one end of the paper tape 1 in the two adjacent paper pot combinations is fixedly connected, so that the three paper pot combinations form an S-shaped fixed connection, so that the individual paper pots 100 in the three paper pot combinations can be transferred in sequence.

[0069] Of course, in order to improve the efficiency of raising seedlings, more paper pot components can be connected in a similar manner. Figure 8 As shown, five paper bowl assemblies are arranged in an array, the paper bowl assemblies are connected in sequence, and three adjacent paper bowl assemblies are fixedly connected in an S shape or an inverted S shape.

[0070] Preferably, in the above steps, a paper tape 1 can also be used, and multiple paper sheets 2 can be glued to the paper tape 1 to form a plurality of paper bowl assemblies connected as one body, which also falls within the scope of protection of the present invention.

[0071] More preferably, in step S31, the following is further included:

[0072] Along a preset first direction, two adjacent rows of paper pot assemblies are staggered, with the staggered distance being 0.5 times the length h of the paper sheet 2 , and the directions of the two adjacent staggered arrangements being opposite.

[0073] Specifically, if Figure 8 、 Figure 9As shown, during the seedling raising process, it is necessary to fill the matrix into the individual paper pots 100, which will cause the volume of the individual paper pots 100 to increase along the thickness direction of the paper strip 1. At this time, due to the staggered arrangement of the two adjacent rows of individual paper pots 100, this volume change also becomes a staggered distribution. After filling the matrix, along the length direction of the paper strip 1, the thickness of the individual paper pots 100 presents a small-large-small shape. At this time, by staggering the two adjacent rows of individual paper pots 100, the position with a larger thickness dimension of the individual paper pots 100 in the previous row can be directly abutted with the position with a smaller thickness dimension of the individual paper pots 100 in the next row, thereby making the total thickness dimension of the two rows of individual paper pots 100 smaller, reducing the occupied area requirements during seedling raising. Preferably, each individual paper pot 100 presents a hexagonal or hexagon-like shape after being filled with the matrix, and multiple individual paper pots 100 can be arranged in a honeycomb shape to achieve a higher space utilization rate.

[0074] Specifically, in order to achieve the above-mentioned staggered setting, after step S20 and before step S31, the following steps are further included:

[0075] S21. An extension area 14 is provided at the end of the paper strip 1 of each paper bowl combination. The length of the extension area 14 is not less than 0.5 times the length h of the paper sheet 2. The extension area 14 is used to fixedly connect the paper strips 1 of two adjacent paper bowl combinations.

[0076] like Figure 8 、 Figure 10 As shown, the setting of the extension area 14 allows for a staggered space between two adjacent rows of paper pot assemblies. Preferably, in this embodiment, the extension area 14 is directly provided on the paper strip 1, that is, the extension area 14 is formed by controlling the spacing of the paper sheets 2 bonded together.

[0077] For example, to achieve staggered placement between two adjacent rows of individual paper pots 100, a portion of the paper sheets 2 between two adjacent individual paper pots 100 are configured as folding zones 13, each folding zone 13 being folded to one or two times the length h of the paper sheet 2. Another portion of the paper sheets 2 between the individual paper pots 100 are configured as folding zones 13 and extension zones 14, with the extension zones 14 being located between any two folds within the folding zones 13. The spacing of the paper sheets 2 includes a first spacing k1 and a second spacing k2, such that a portion of the paper pots 100 are spaced apart by the first spacing k1, while another portion of the paper pots 100 are spaced apart by the second spacing k2. The difference between the first spacing k1 and the second spacing k2 is the length of the extension zone 14. Specifically in this embodiment, the length of the folding area 13 is the first spacing k1, which is approximately 52.8 cm (ideally, k1 should be approximately 8 times the length h of the paper piece 2, but there will be certain fluctuations for reasons such as smooth folding), the length of the extension area 14 is approximately 3.3 cm, and the sum of the length of the folding area 13 and the length of the extension area 14 is the second spacing k2, which is approximately 56.1 cm.

[0078] In order to realize the above-mentioned extension area 14, step S10 further includes:

[0079] At least two groups of paper sheets 2 are bonded to the paper tape 1 , each group of paper sheets 2 includes m paper sheets 2 , and a first spacing k1 between the m paper sheets 2 in each group of paper sheets 2 satisfies:

[0080] k1=2nh, where h is the length of the paper piece 2;

[0081] Furthermore, the second distance k2 between two adjacent groups of paper sheets 2 satisfies:

[0082] k2=(2n+0.5)h.

[0083] For example, when n=4 and the length h of the paper sheet 2 is 6.6 cm, the first spacing k1 is 52.8 cm and the second spacing k2 is 56.1 cm, which can realize the above-mentioned staggered setting. Figure 10 As shown, the first distance k1 and the second distance k2 refer to the length of the paper strip 1 between two paper sheets 2 .

[0084] Therefore, in step S20, it also includes:

[0085] A paper bowl assembly is formed by folding the paper strip 1 to which each group of paper sheets 2 is bonded.

[0086] That is, the paper strip 1 with a group of paper sheets 2 bonded thereto is folded to form a paper bowl assembly, and the portion with the extended area 14 is located between two adjacent paper bowl assemblies after folding. For example, in this embodiment, m=5, i.e., every five paper sheets 2 are arranged in a group.

[0087] The present invention also provides a chain paper pot, which is manufactured using the above-mentioned chain paper pot manufacturing method. The chain paper pot is suitable for chain paper pots for crops with large planting spacing, such as flue-cured tobacco, and can achieve a large planting spacing while hiding the longer paper strip 1 between the two individual paper pots 100 through a special folding structure, thereby enabling the chain paper pot to be stored and raised in a smaller volume, greatly reducing transportation, storage, and seedling raising costs. At the same time, this folding structure mainly adopts a reciprocating folding strategy, setting the folds in the same direction at a position away from the individual paper pots 100, which can make the chain paper pot dragging smoother during the transfer process, reducing phenomena such as seedling falling and jamming.
