[0055] Embodiment 1

[0056] See also Figure 1 , which is a flow chart of a linear programming method for bamboo chopstick segmentation in Embodiment 1 of the present invention, and the linear programming method for bamboo chopstick segmentation includes the following steps S01 to S03, wherein:

[0057] Step S01, obtaining the density of bamboo nodes and the length of internodes, and cutting the bamboo into several sections based on the length of bamboo nodes and the length of internodes.

[0058] In the whole bamboo, the bamboo nodes at the root are denser and thicker, so the internode length at the root is shorter;

[0059] The density of bamboo nodes in the middle of the bamboo is lower than that in the root of the bamboo, and the bamboo nodes are thinner, so the internode length in the middle of the bamboo is greater than that in the root of the bamboo;

[0060] The distance between adjacent bamboo nodes at the top of the bamboo is farther and the bamboo nodes are smaller, so the internode length at the top of the bamboo is the largest;

[0061] Then, compared with the root and top of the bamboo, the middle part of the bamboo is more suitable for making bamboo chopsticks.

[0062] Based on the density of bamboo nodes and the length of internodes, the whole bamboo is cut into bamboo top section, bamboo middle section and bamboo root section, and the bamboo top section, bamboo middle section and bamboo root section are processed to obtain sawn pieces, and the sawn pieces include bamboo top strips, bamboo middle strips and bamboo root strips.

[0063] It is worth noting that due to the limitations of equipment processing, the lengths of the bamboo top strips, bamboo middle strips, and bamboo root strips shall not exceed 1.6m, and when processing the bamboo top section, bamboo middle section, and bamboo root section, in order to ensure a smooth incision, the thickness of the cut waste is required to be no less than 0.5cm.

[0064] Step S02: based on the distance limit of the bamboo nodes, adaptive cutting rules are set for different types of sawn pieces to perform cutting.

[0065] The bamboo top strips, bamboo middle strips, and bamboo root strips are cut to obtain the five types of bamboo chopsticks mentioned above, namely, nodeless bamboo chopsticks, left-node bamboo chopsticks, right-node bamboo chopsticks, middle-node bamboo chopsticks, and random-node bamboo chopsticks. Among them, the bamboo nodes in the left-node bamboo chopsticks are biased towards the left end of the bamboo chopsticks, the bamboo nodes in the right-node bamboo chopsticks are biased towards the right end of the bamboo chopsticks, the bamboo nodes in the middle-node bamboo chopsticks are located in the middle part of the bamboo chopsticks, and the bamboo nodes in the random-node bamboo chopsticks are scattered (there may be multiple bamboo nodes).

[0066] In order to improve the aesthetics of bamboo chopsticks and thus increase their value, a distance limit for bamboo nodes is set. The distance limit is: the bamboo node in the left-jointed bamboo chopstick must be within dcm of the left end of the bamboo chopstick, the bamboo node in the right-jointed bamboo chopstick must be within dcm of the right end of the bamboo chopstick, and the bamboo node in the middle-jointed bamboo chopstick must be within d / 2cm of the center of the bamboo chopstick.

[0067] Since the bamboo joints of the bamboo root strip are relatively dense, the length of the cutting bamboo chopsticks is set. In this embodiment, the cutting length is usually set to 24cm. Therefore, the best bamboo chopsticks for cutting bamboo root strips are usually the left straight-joint bamboo chopsticks or the right straight-joint bamboo chopsticks of the first section. The left and right straight-joint bamboo chopsticks are both random-joint bamboo chopsticks. The length of the random-joint bamboo chopsticks is required to be within the range of 18cm-30cm, and then they only need to be cut in order.

[0068] According to the internode length of the middle bamboo strips, the middle bamboo strips are cut according to the value priority principle, the no-node priority principle and the even number priority principle.

[0069] It can be understood that, based on the solution of this embodiment, in the process of cutting the middle bamboo strip into bamboo chopsticks, the length of the bamboo chopsticks obtained by cutting is controlled to be as long as possible 24cm. Based on this, in order to maximize the value, the cutting of the bamboo chopsticks without knots is given priority, and the length of the excess cut bamboo chopsticks is guaranteed to be between 18cm-30cm, and finally the number of pairs is cut. For example, if 5 pairs of bamboo chopsticks can be cut when cutting a middle bamboo strip, 5 pairs of bamboo chopsticks will be produced; in the case of cutting 4.5 pairs, 4 pairs of 24cm non-knotted bamboo chopsticks will be cut first; if they cannot be evenly cut into non-knotted bamboo chopsticks, the remaining length can be used to cut bamboo chopsticks with a length greater than 24cm while ensuring the number of non-knotted bamboo chopsticks. It is worth noting that when cutting the middle bamboo strip, try to avoid cutting bamboo chopsticks with messy knots.

[0070] Similarly, according to the internode length of the bamboo top strips, follow the value priority principle and the even number priority principle.

[0071] Step S03, calculating the value of the sawed-off material based on the distance limit and the length of the bamboo chopsticks.

[0072] Based on the adaptive cutting rule in step S02, the value calculation formula of any bamboo top strip, bamboo middle strip, or bamboo root strip is:

[0073] V max =V1+V2+V3+…+V n

[0074] Among them, V max is the total value of the current sawn material, V1, V2, V3 and V n is the value of each bamboo chopstick, n is the serial number of the bamboo chopsticks cut into pieces;

[0075] The formula for calculating the value of each piece of bamboo chopsticks is:

[0076] V n =P n ×K n ×J n

[0077] Among them, P n is the basic value of bamboo chopsticks, K n is the scarcity coefficient adaptively adjusted based on the position of the bamboo node, J n It is a reduction coefficient based on the number of bamboo nodes; the scarcity coefficient is set based on the position of the bamboo nodes on the bamboo chopsticks. It is worth noting that when the bamboo chopsticks are nodeless bamboo chopsticks, the scarcity coefficient is the largest and is 1. The scarcity coefficient of left-node bamboo chopsticks and / or right-node bamboo chopsticks is less than 1 and greater than the scarcity coefficient of middle-node bamboo chopsticks. The scarcity coefficient of disordered-node bamboo chopsticks is the smallest.

[0078] The basic value of bamboo chopsticks P n The calculation formula is:

[0079] P n =S×L n

[0080] Among them, S is the basic value ratio calculation coefficient, L n is the length of the bamboo chopsticks.

[0081] In summary, according to the segmented linear programming method of bamboo chopsticks proposed by the present invention, the whole bamboo is sawed into three sections and processed into corresponding bamboo strips according to the density of bamboo sections and the length of internodes of the whole bamboo; and based on the convenience of use and aesthetics, the position of the bamboo sections on the bamboo chopsticks is set, and adaptive cutting rules are set for different types of bamboo strips according to the distance limit of the bamboo sections to maximize the economic effect; finally, the value of each bamboo chopstick is calculated according to the influencing factors such as the length of the bamboo chopsticks, the position of the bamboo sections and the number, and finally the value of the bamboo strips is calculated. The present invention uses the distance limit of the bamboo sections on the bamboo chopsticks to set adaptive cutting rules to replace the traditional direct cutting method, thereby improving the aesthetics of the bamboo chopsticks, thereby improving the selling value of the bamboo chopsticks and increasing revenue.

[0082] Embodiment 2

[0083] See also Figure 2-Figure 5 , which is a schematic structural diagram of a bamboo chopstick cutting device in Embodiment 2 of the present invention, the bamboo chopstick cutting device comprises a support bracket 400, a transmission assembly 110 disposed on the support bracket 400, a pusher assembly 300 disposed on both sides of the support bracket 400, and a cutting assembly 200 disposed at one end of the support bracket 400 away from the transmission mechanism, wherein:

[0084] In order to transport bamboo strips, the transmission assembly 110 includes a power mechanism 110 arranged at the lower layer of the support bracket 400, a first transmission mechanism 120, a second transmission mechanism 130, and a third transmission mechanism 140 arranged at the upper layer of the support bracket 400. The power mechanism 110 is respectively connected to the first transmission mechanism 120, the second transmission mechanism 130 and the third transmission mechanism 140 and drives the above-mentioned transmission mechanisms to rotate, so as to realize the function of transporting bamboo strips.

[0085] Specifically, the power mechanism 110 includes a transmission motor 111 disposed at the lower layer of the support bracket 400, a first transmission shaft 112 disposed on the transmission motor 111, and a second transmission shaft 113 meshingly connected with the first transmission shaft 112, wherein, in order to drive the first transmission mechanism 120 and the third transmission mechanism 140 to rotate, a first gear 114 for connecting with the first transmission belt 123 and a third gear 116 for connecting with the third transmission belt 143 are respectively disposed at both ends of the second transmission shaft 113, and in order to drive the second transmission mechanism 130 to rotate, a second gear 115 connected with the second transmission belt 133 is disposed at one end of the transmission motor 111 away from the second transmission shaft 113. Since the transmission direction of the first transmission mechanism 120 is the same as the transmission direction of the third transmission mechanism 140, and both are perpendicular to the transmission direction of the second transmission mechanism 130, the first gear 114 and the third gear 116 are disposed in parallel, and the setting direction of the second gear 115 is perpendicular to the setting directions of the first gear 114 and the second gear 115.

[0086] In addition, if the transmission directions of the first transmission mechanism and the second transmission mechanism 130 need to be opposite, the second transmission shaft 113 can be provided with "staggered teeth" or a transmission can be added to make the rotation directions of the first gear 114 and the third gear 116 opposite.

[0087] In order to connect with the power mechanism 110, the first transmission mechanism 120 includes two first transmission rollers 121, a first transmission crawler 122 sleeved on the two first transmission rollers 121, and a first transmission belt 123 arranged between the first transmission rollers 121 and between the first transmission rollers 121 and the first gear 114;

[0088] The second transmission mechanism 130 includes two second transmission rollers 131, a second transmission crawler 132 sleeved on the two second transmission rollers 131, and a second transmission belt 133 disposed between the second transmission rollers 131 and between the second transmission rollers 131 and the second gear 115;

[0089] The third transmission mechanism 140 includes two third transmission rollers 141, a third transmission crawler 142 sleeved on the two third transmission rollers 141, and a third transmission belt 143 disposed between the third transmission rollers 141 and between the third transmission rollers 141 and the third gear 116;

[0090] In this embodiment, since gears are provided on one side of the first transmission roller, the second transmission roller 131, and the third transmission roller 141, racks are used to connect the gears provided on the transmission rollers to the first gear 114, the second gear 115, and the third gear 116 respectively. The transmission motor 111 outputs power to drive the second gear 115 to rotate, and then drives the second transmission shaft 113 to rotate, so that the second transmission crawler 132 rolls along the length direction of the bamboo strips, and then transports the bamboo strips to a preset position. When the bamboo strips are transported by the second transmission crawler 132 to abut against the baffle 410 arranged on the upper side of the support bracket 400, the second gear 115 is controlled to stop rotating, and drives the first transmission shaft 112 to rotate, and then drives the first transmission roller 121 and the second transmission roller 131 to rotate synchronously, so that the first transmission crawler 122 and the second transmission crawler 132 rotate toward one side of the support bracket 400, so as to transmit the bamboo strips to the pushing assembly 300 on both sides of the support bracket 400, and then push the bamboo strips to the cutting assembly 200 to cut and segment them into bamboo chopsticks.

[0091] In order to push the bamboo strips to the cutting assembly 200, the pushing assembly 300 includes a first pushing mechanism 310 disposed on both sides of the support bracket 400, and a second pushing mechanism 320 disposed on both sides of the collecting mechanism 220. The first pushing mechanism 310 includes a pushing track 311 disposed on both sides of the support bracket 400, a second moving motor 312 disposed on the pushing track 311, and a pushing member 313. The length of the pushing track 311 is greater than the sum of the lengths of the first transmission track 122, the second transmission track 132, and the third transmission track 142, so as to ensure that when the bamboo strips are fed into the pushing track 311, the pushing member 313 can be pushed to the cutting assembly 200 under the push of the second moving motor 312.

[0092] Furthermore, when the bamboo strips are pushed to the port of the pushing track 311 close to the cutting assembly 200, the cutting assembly 200 starts to operate. The cutting assembly 200 includes a cutting mechanism 210 symmetrically arranged on both sides of the support bracket 400, and a collecting mechanism 220 arranged between the cutting mechanisms 210 on both sides. The cutting mechanism 210 includes a first moving motor 211 arranged on the support bracket 400, and a cutting member 212 rotating on the first moving motor 211. The first moving motor 211 drives the cutting member 212 to move in a direction perpendicular to the pushing track 311 while also driving the cutting member 212 to rotate. The pushing member 313 pushes the bamboo strips to move, and then the cut bamboo chopsticks are collected on the second pushing mechanism 320. It is worth noting that the second pushing mechanism 320 is arranged at the port of the material withdrawal track, and the cutting member 212 is arranged between the second pushing mechanism 320 and the pushing track 311.

[0093] In order to push the bamboo chopsticks into the collecting mechanism 220, the second pushing mechanism 320 includes support plates 321 disposed on both sides of the collecting mechanism 220, and a pushing plate 322 moving along the length direction of the support plate 321. One end of the support plate 321 is disposed at the end of the pushing track 311, and the other end is disposed at the entrance of the collecting mechanism 220. When the bamboo strips are cut into bamboo chopsticks, the pushing plate 322 is disposed at one end of the support plate 321 away from the collecting mechanism 220, until the bamboo strips are cut at a certain stage, and the pushing plate 322 moves toward the collecting mechanism 220 based on electrical control to sweep the bamboo chopsticks into the collecting mechanism 220.

[0094] Furthermore, the collecting mechanism 220 includes a collecting pipe 221, a plurality of collecting buckets 222 symmetrically arranged on both sides of the collecting pipe 221, and a gripper 223 arranged at the mouth of the collecting bucket 222. In order to collect the bamboo chopsticks in the collecting pipe 221 into the collecting bucket 222 through the gripper 223, a cylinder 224 is provided on the side of the collecting bucket 222 close to the baffle 410, and the cylinder 224 is connected to the gripper 223. When the push plate 322 pushes the bamboo chopsticks on the supporting plate 321 into the collecting pipe 221, the cylinder 224 drives the gripper 223 to move toward the collecting pipe 221. Since the gripper 223 is arranged obliquely, when the gripper 223 is obliquely intercepted in the collecting pipe 221, the bamboo chopsticks falling into the gripper 223 slide into the collecting bucket 222, thereby completing the collection of the bamboo chopsticks. In this embodiment, the collecting pipe 221 is vertically arranged on the supporting bracket 400, and three layers of collecting buckets 222 are symmetrically arranged on both sides of the collecting pipe 221, which are respectively used to collect bamboo chopsticks made of bamboo top strips, bamboo middle strips, and bamboo root strips.

[0095] In summary, according to the bamboo chopstick cutting device proposed in this embodiment, the bamboo strips are transmitted to the pushing track through the first transmission mechanism, the second transmission mechanism and the third transmission mechanism, the bamboo strips are pushed to the cutting member by the pushing member, and the cut bamboo chopsticks are pushed into the collection pipe through the pushing plate, and finally the collection is completed by the gripper.

[0097] Another aspect of the present invention is to provide a bamboo chopstick segmentation linear programming system, please refer to Figure 6 , which is a schematic diagram of the structure of the bamboo chopstick segmentation linear programming system in the second embodiment of the present invention, and the bamboo chopstick segmentation linear programming system includes:

[0098] The bamboo strip classification module 11 is used to obtain the density of bamboo nodes and the length of internodes, and cut the bamboo into several sections and saw off the materials based on the length of bamboo nodes and the length of internodes;

[0099] A rule setting module 12 is used to set adaptive cutting rules for different types of sawn materials based on the distance limit of the bamboo nodes, so as to perform cutting;

[0100] The value calculation module 13 is used to calculate the value of the sawed-off material based on the distance limit and the length of the bamboo chopsticks.

[0101] In the whole bamboo, the bamboo nodes at the root are denser and thicker, so the internode length at the root is shorter;

[0102] The density of bamboo nodes in the middle of the bamboo is lower than that in the root of the bamboo, and the bamboo nodes are thinner, so the internode length in the middle of the bamboo is greater than that in the root of the bamboo;

[0103] The distance between adjacent bamboo nodes at the top of the bamboo is farther and the bamboo nodes are smaller, so the internode length at the top of the bamboo is the largest;

[0104] Then, compared with the root and top of the bamboo, the middle part of the bamboo is more suitable for making bamboo chopsticks.

[0105] Based on the density of bamboo nodes and the length of internodes, the whole bamboo is cut into bamboo top section, bamboo middle section and bamboo root section, and the bamboo top section, bamboo middle section and bamboo root section are processed to obtain sawn pieces, and the sawn pieces include bamboo top strips, bamboo middle strips and bamboo root strips.

[0106] It is worth noting that due to the limitations of equipment processing, the lengths of the bamboo top strips, bamboo middle strips, and bamboo root strips shall not exceed 1.6m, and when processing the bamboo top section, bamboo middle section, and bamboo root section, in order to ensure a smooth incision, the thickness of the cut waste is required to be no less than 0.5cm.

[0107] The bamboo top strips, bamboo middle strips, and bamboo root strips are cut to obtain the five types of bamboo chopsticks mentioned above, namely, nodeless bamboo chopsticks, left-node bamboo chopsticks, right-node bamboo chopsticks, middle-node bamboo chopsticks, and random-node bamboo chopsticks. Among them, the bamboo nodes in the left-node bamboo chopsticks are biased towards the left end of the bamboo chopsticks, the bamboo nodes in the right-node bamboo chopsticks are biased towards the right end of the bamboo chopsticks, the bamboo nodes in the middle-node bamboo chopsticks are located in the middle part of the bamboo chopsticks, and the bamboo nodes in the random-node bamboo chopsticks are scattered (there may be multiple bamboo nodes).

[0108] In order to improve the aesthetics of bamboo chopsticks and thus increase their value, a distance limit for bamboo nodes is set. The distance limit is: the bamboo node in the left-jointed bamboo chopstick must be within dcm of the left end of the bamboo chopstick, the bamboo node in the right-jointed bamboo chopstick must be within dcm of the right end of the bamboo chopstick, and the bamboo node in the middle-jointed bamboo chopstick must be within d / 2cm of the center of the bamboo chopstick.

[0109] Since the bamboo joints of the bamboo root strip are relatively dense, the length of the cutting bamboo chopsticks is set. In this embodiment, the cutting length is usually set to 24cm. Therefore, the best bamboo chopsticks for cutting bamboo root strips are usually the left straight-joint bamboo chopsticks or the right straight-joint bamboo chopsticks of the first section. The left and right straight-joint bamboo chopsticks are both random-joint bamboo chopsticks. The length of the random-joint bamboo chopsticks is required to be within the range of 18cm-30cm, and then they only need to be cut in order.

[0110] According to the internode length of the middle bamboo strips, the middle bamboo strips are cut according to the value priority principle, the no-node priority principle and the even number priority principle.

[0111] It can be understood that, based on the solution of this embodiment, in the process of cutting the middle bamboo strip into bamboo chopsticks, the length of the bamboo chopsticks obtained by cutting is controlled to be as long as possible 24cm. Based on this, in order to maximize the value, the cutting of the bamboo chopsticks without knots is given priority, and the length of the excess cut bamboo chopsticks is guaranteed to be between 18cm-30cm, and finally the number of pairs is cut. For example, if 5 pairs of bamboo chopsticks can be cut when cutting a middle bamboo strip, 5 pairs of bamboo chopsticks will be produced; in the case of cutting 4.5 pairs, 4 pairs of 24cm non-knotted bamboo chopsticks will be cut first; if they cannot be evenly cut into non-knotted bamboo chopsticks, the remaining length can be used to cut bamboo chopsticks with a length greater than 24cm while ensuring the number of non-knotted bamboo chopsticks. It is worth noting that when cutting the middle bamboo strip, try to avoid cutting bamboo chopsticks with messy knots.

[0112] Similarly, according to the internode length of the bamboo top strips, follow the value priority principle and the even number priority principle.

[0113] Based on the adaptive cutting rule in step S02, the value calculation formula of any bamboo top strip, bamboo middle strip, or bamboo root strip is:

[0114] V max =V1+V2+V3+…+V n

[0115] Among them, Vmax is the total value of the current sawn material, V1, V2, V3 and V n is the value of each bamboo chopstick, n is the serial number of the bamboo chopsticks cut into pieces;

[0116] The value of each piece of bamboo chopsticks is calculated as follows:

[0117] V n =P n ×K n ×J n

[0118] Among them, P n is the basic value of bamboo chopsticks, K n is the scarcity coefficient adaptively adjusted based on the position of the bamboo node, J n It is a reduction coefficient based on the number of bamboo nodes; the scarcity coefficient is set based on the position of the bamboo nodes on the bamboo chopsticks. It is worth noting that when the bamboo chopsticks are nodeless bamboo chopsticks, the scarcity coefficient is the largest and is 1. The scarcity coefficient of left-node bamboo chopsticks and / or right-node bamboo chopsticks is less than 1 and greater than the scarcity coefficient of middle-node bamboo chopsticks. The scarcity coefficient of disordered-node bamboo chopsticks is the smallest.

[0119] The basic value of bamboo chopsticks P n The calculation formula is:

[0120] P n =S×L n

[0121] Among them, S is the basic value ratio calculation coefficient, L n is the length of the bamboo chopsticks.

[0122] In summary, according to the bamboo chopstick segmentation linear programming system proposed by the present invention, the whole bamboo is sawed into three sections and processed into corresponding bamboo strips according to the density of bamboo sections and the length of internodes of the whole bamboo; and based on the convenience of use and aesthetics, the position of the bamboo sections on the bamboo chopsticks is set, and adaptive cutting rules are set for different types of bamboo strips according to the distance limit of the bamboo sections to maximize the economic effect; finally, the value of each bamboo chopstick is calculated according to the influencing factors such as the length of the bamboo chopsticks, the position of the bamboo sections and the number, and finally the value of the bamboo strips is calculated. The present invention uses the distance limit of the bamboo sections on the bamboo chopsticks to set adaptive cutting rules to replace the traditional direct cutting method, thereby improving the aesthetics of the bamboo chopsticks, thereby improving the selling value of the bamboo chopsticks and increasing revenue.
