As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0054] Embodiment one

[0055] Referring to FIG. 1, a flow chart of a bamboo chopstick segmentation linear programming method according to an embodiment of the present application is shown, which comprises the following steps S01-S03: Figure 1

[0056] In step S01, the bamboo node density and the internode length are obtained, and the whole bamboo is cut into several segments based on the node length and the internode length.

[0057] The node density of the bamboo root is higher and the node is thicker, so the internode length of the bamboo root is shorter.

[0058] The node density of the bamboo middle part is lower than that of the bamboo root, and the node is thinner, so the internode length of the bamboo middle part is greater than that of the bamboo root.

[0059] The distance between the adjacent nodes of the bamboo top part is far and the node is small, so the internode length of the bamboo top part is the largest.

[0060] Then, compared with the bamboo root and the bamboo top part, the bamboo middle part is more suitable for making bamboo chopsticks.

[0061] Based on the bamboo node density and the internode length, the whole bamboo is cut into a bamboo top segment, a bamboo middle segment, and a bamboo root segment, and the bamboo top segment, the bamboo middle segment, and the bamboo root segment are processed to obtain the sawn-off material, and the sawn-off material comprises a bamboo top strip, a bamboo middle strip, and a bamboo root strip.

[0062] It is to be understood that based on the limitation of equipment processing, the length of the distance of the bamboo top strip, the bamboo middle strip, and the bamboo root strip is not more than 1.6 m, and when processing the bamboo top segment, the bamboo middle segment, and the bamboo root segment, in order to ensure the flatness of the cut, the thickness of the waste material cut down is required to be not less than 0.5 cm.​

[0063] Step S02, based on the distance limit of the node, adaptive cutting rules are set for different types of sawn-off materials to be cut.

[0064] The top strip, middle strip and root strip are cut to obtain five types of bamboo skewers, i.e. non-node bamboo skewer, left node bamboo skewer, right node bamboo skewer, middle node bamboo skewer and random node bamboo skewer. In the left node bamboo skewer, the node is located at the left end of the bamboo skewer. In the right node bamboo skewer, the node is located at the right end of the bamboo skewer. In the middle node bamboo skewer, the node is located at the middle of the bamboo skewer. In the random node bamboo skewer, the node is randomly distributed (there can be multiple nodes).

[0065] In order to improve the appearance of the bamboo skewer and thus the value of the bamboo skewer, a distance limit of the node is set. The distance limit is that the node of the left node bamboo skewer must be within dcm from the left end of the bamboo skewer, the node of the right node bamboo skewer must be within dcm from the right end of the bamboo skewer, and the node of the middle node bamboo skewer must be within d / 2cm from the center of the bamboo skewer.

[0066] Since the nodes of the root strip are relatively dense, the length of the cut bamboo skewer is set. In this embodiment, the length of the cut bamboo skewer is usually set to 24cm. Therefore, the optimal bamboo skewer cut from the root strip is usually the left node bamboo skewer or the right node bamboo skewer of the first segment, which is a random node bamboo skewer. The length of the random node bamboo skewer is required to be within the range of 18cm-30cm, and thus only needs to be cut in sequence.

[0067] According to the length of the node interval of the middle strip, the middle strip is cut in accordance with the value priority rule, the non-node priority rule and the even number priority rule.

[0068] It can be understood that, based on the scheme of this embodiment, the length of the cut bamboo skewer is controlled to be as close to 24cm as possible during the cutting of the middle strip into bamboo skewers. In order to maximize the value, the non-node bamboo skewer is cut first, and the remaining length is ensured to be within the range of 18cm-30cm. Finally, the even number is cut. For example, if 5 pairs of bamboo skewers can be cut from a middle strip, 5 pairs of bamboo skewers are output. If 4.5 pairs of bamboo skewers are cut, 4 pairs of 24cm non-node bamboo skewers are cut first. If it is not possible to cut non-node bamboo skewers, the remaining length can be used to cut bamboo skewers with a length greater than 24cm. It should be noted that, during the cutting of the middle strip, random node bamboo skewers are avoided as much as possible.

[0069] Similarly, according to the length of the node interval of the top strip, the top strip is cut in accordance with the value priority rule and the even number priority rule.

[0070] Step S03, based on the distance limit and the length of the bamboo skewer, the value of the sawn-off material is calculated.

[0071] Based on the adaptive cutting rule in step S02, the value calculation formula of any one of the top bamboo strip, or the middle bamboo strip, or the root bamboo strip is:

[0072]

[0073] wherein, is the total value of the sawn-off material, , , and is the value of each bamboo chopstick, is the serial number of the bamboo chopstick cut by the sawn-off material;

[0074] The value calculation formula of each segment of the bamboo chopstick is:

[0075]

[0076] wherein, is the basic value of the bamboo chopstick, is an adaptive adjustment of the scarcity coefficient based on the position of the node, is a reduction coefficient based on the number of nodes; the scarcity coefficient is set based on the position of the node on the bamboo chopstick, and it is worth noting that when the bamboo chopstick is a nodeless bamboo chopstick, the scarcity coefficient is the largest, with a value of 1, and the scarcity coefficients of the left and right straight node bamboo chopsticks are less than 1 and greater than the scarcity coefficient of the middle node bamboo chopstick, wherein the scarcity coefficient of the random node bamboo chopstick is the smallest.

[0077] The basic value of the bamboo chopstick is calculated by the formula:

[0078]

[0079] wherein, is the basic value proportion calculation coefficient, is the length of the bamboo chopstick.

[0080] In summary, according to the bamboo chopstick segmentation linear programming method proposed by the present application, according to the node density and the length of the internode of the whole bamboo, the whole bamboo is sawn into three segments and processed into corresponding bamboo strips; and based on the convenience of use and the beauty, the position of the node on the bamboo chopstick is set, and adaptive cutting rules are set for different types of bamboo strips according to the distance limit of the node, so as to maximize the economic effect; finally, the value of each bamboo chopstick is calculated according to the length of the bamboo chopstick, the position and number of nodes and other influencing factors, and the value of the bamboo strip is finally calculated. The present application uses the distance limit of the node on the bamboo chopstick to set adaptive cutting rules to replace the traditional direct cutting method, which improves the beauty of the bamboo chopstick, and thus improves the selling value of the bamboo chopstick and increases the revenue.

[0081] Example two

[0082] Please refer to Figures 2-5 , it is a structure schematic diagram of a bamboo chopstick cutting device in the second embodiment of the present application, the bamboo chopstick cutting device comprises a support bracket 400, a transmission assembly 110 arranged on the support bracket 400, a pushing assembly 300 arranged on both sides of the support bracket 400, and a cutting assembly 200 arranged on the end of the support bracket 400 away from the transmission assembly, wherein:

[0083] In order to transport bamboo strips, the transmission assembly 110 comprises a power mechanism 110 arranged on the lower layer of the support bracket 400, a first transmission mechanism 120 arranged on the upper layer of the support bracket 400, a second transmission mechanism 130, and a third transmission mechanism 140. The power mechanism 110 drives the above-mentioned transmission mechanisms to rotate by being connected with the first transmission mechanism 120, the second transmission mechanism 130, and the third transmission mechanism 140 respectively, so as to realize the function of transporting bamboo strips.

[0084] Specifically, the power mechanism 110 comprises a transmission motor 111 arranged on the lower layer of the support bracket 400, a first transmission shaft 112 arranged on the transmission motor 111, and a second transmission shaft 113 meshed and connected with the first transmission shaft 112. In order to drive the first transmission mechanism 120 and the third transmission mechanism 140 to rotate, a first gear 114 for connecting with a first transmission belt 123 is arranged on both ends of the second transmission shaft 113, and a third gear 116 for connecting with a third transmission belt 143 is arranged on both ends of the second transmission shaft 113. In order to drive the second transmission mechanism 130 to rotate, a second gear 115 for connecting with a second transmission belt 133 is arranged on the end of the transmission motor 111 away from the second transmission shaft 113. Since the transmission direction of the first transmission mechanism 120 and the transmission direction of the third transmission mechanism 140 are the same, and both are perpendicular to the transmission direction of the second transmission mechanism 130, the first gear 114 and the third gear 116 are arranged in parallel, and the arrangement direction of the second gear 115 is perpendicular to the arrangement direction of the first gear 114 and the second gear 115.

[0085] In addition, if it is necessary to make the transmission direction of the first transmission mechanism and the second transmission mechanism 130 opposite, the second transmission shaft 113 can be provided with "staggered teeth" or a speed changer, so that the rotation direction of the first gear 114 and the third gear 116 is opposite.

[0086] In order to be connected with the power mechanism 110, the first transmission mechanism 120 comprises two first transmission rollers 121, a first transmission track 122 sleeved on the two first transmission rollers 121, and a first transmission belt 123 arranged between the two first transmission rollers 121 and between the first transmission roller 121 and the first gear 114;

[0087] The second transmission mechanism 130 comprises two second transmission rollers 131, a second transmission track 132 sleeved on the two second transmission rollers 131, and a second transmission belt 133 arranged between the two second transmission rollers 131 and between the two second transmission rollers 131 and the second gear 115.

[0088] The third transmission mechanism 140 comprises two third transmission rollers 141, a third transmission track 142 sleeved on the two third transmission rollers 141, and a third transmission belt 143 arranged between the two third transmission rollers 141 and between the two third transmission rollers 141 and the third gear 116.

[0089] In the embodiment, the first transmission roller, the second transmission roller 131, and the third transmission roller 141 are all provided with gears on one side, and the gears on the transmission rollers are connected with the first gear 114, the second gear 115, and the third gear 116 respectively by using a rack. The power output by the transmission motor 111 drives the second gear 115 to rotate, and then drives the second transmission shaft 113 to rotate, so that the second transmission track 132 rolls along the length direction of the bamboo strip, and then the bamboo strip is transported to a preset position. When the bamboo strip is transported by the second transmission track 132 to abut against the baffle 410 provided on the support bracket 400, the second gear 115 is controlled to stop rotating, and the first transmission shaft 112 is driven to rotate, and then the first transmission roller 121 and the third transmission roller 141 are synchronously driven to rotate, so that the first transmission track 122 and the third transmission track 142 are rotated towards one side of the support bracket 400, so as to convey the bamboo strip to the pushing assembly 300 on both sides of the support bracket 400, and then the bamboo strip is pushed to the cutting assembly 200 to be cut into bamboo chopsticks.

[0090] In order to push the bamboo strip to the cutting assembly 200, the pushing assembly 300 comprises a first pushing mechanism 310 arranged on both sides of the support bracket 400 and a second pushing mechanism 320 arranged on both sides of the collecting mechanism 220. The first pushing mechanism 310 comprises a pushing track 311 arranged on both sides of the support bracket 400, a second moving motor 312 and a pushing piece 313 arranged on the pushing track 311. 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 strip is sent into the pushing track 311, the pushing piece 313 can be pushed to the cutting assembly 200 under the pushing of the second moving motor 312.

[0091] Further, when the bamboo strip is pushed to the end of the pushing track 311 close to the cutting assembly 200, the cutting assembly 200 starts to work. The cutting assembly 200 includes cutting mechanisms 210 symmetrically arranged on both sides of the support bracket 400 and a collecting mechanism 220 arranged between the two cutting mechanisms 210. The cutting mechanism 210 includes a first moving motor 211 arranged on the support bracket 400, a cutting member 212 arranged on the first moving motor 211 and rotating, the first moving motor 211 drives the cutting member 212 to move in a direction perpendicular to the pushing track 311 and also drives the cutting member 212 to rotate. The pushing member 313 pushes the bamboo strip 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 end of the material returning track, and the cutting member 212 is arranged between the second pushing mechanism 320 and the pushing track 311.

[0092] In order to push the bamboo chopsticks into the collecting mechanism 220, the second pushing mechanism 320 includes support plates 321 arranged 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 arranged at the end of the pushing track 311, and the other end is arranged at the entrance of the collecting mechanism 220. When the bamboo strip is cut into bamboo chopsticks, the pushing plate 322 is arranged at the end of the support plate 321 away from the collecting mechanism 220, until a certain stage when the bamboo strip is cut, the pushing plate 322 moves towards the collecting mechanism 220 based on electrical control, so as to sweep the bamboo chopsticks into the collecting mechanism 220.

[0093] Further, the collecting mechanism 220 includes a collecting pipe 221, a plurality of collecting hoppers 222 symmetrically arranged on both sides of the collecting pipe 221, and a gripper 223 arranged at the hopper opening of the collecting hopper 222. In order to gather the bamboo chopsticks in the collecting pipe 221 into the collecting hopper 222 by the gripper 223, a pneumatic cylinder 224 is arranged on the side of the collecting hopper 222 close to the baffle 410, and the pneumatic cylinder 224 is connected to the gripper 223. After the pushing plate 322 pushes the bamboo chopsticks on the support plate 321 into the collecting pipe 221, the pneumatic cylinder 224 drives the gripper 223 to move towards the collecting pipe 221. Since the gripper 223 is arranged obliquely, when the gripper 223 is arranged obliquely in the collecting pipe 221, the bamboo chopsticks falling into the gripper 223 slide into the collecting hopper 222, thereby completing the collection of the bamboo chopsticks. In the embodiment, the collecting pipe 221 is arranged vertically on the support bracket 400, and three layers of collecting hoppers 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.

[0094] In summary, according to the bamboo chopstick cutting device provided in the embodiment, the bamboo strips are conveyed 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 collecting pipeline by the pushing plate, and finally the collection is completed by the gripper. The present application realizes the functions of automatic conveying, automatic cutting and automatic collection of bamboo strips, reduces the labor input, and improves the cutting and collection efficiency.

[0095] Embodiment three

[0096] The present application also provides a bamboo chopstick segmentation linear programming system, please refer to Figure 6 , which is a structural schematic diagram of the bamboo chopstick segmentation linear programming system in the second embodiment of the present application. The bamboo chopstick segmentation linear programming system comprises:

[0097] A bamboo strip classification module 11 is used to obtain the bamboo joint density and the joint length, and based on the joint length and the joint length, the bamboo is cut into several sawn-off materials;

[0098] A rule setting module 12 is used to set adaptive cutting rules for different types of sawn-off materials based on the distance limit of the bamboo joints, so as to cut;

[0099] A value calculation module 13 is used to calculate the value of the sawn-off materials based on the distance limit and the length of the bamboo chopsticks.

[0100] In the whole bamboo, the bamboo joints in the root part are more dense and thick, so the joint length of the root part is shorter;

[0101] The bamboo joints in the middle part are less dense and thinner than those in the root part, so the joint length of the middle part is greater than that of the root part;

[0102] The distance between the adjacent bamboo joints in the top part is far and the bamboo joints are small, so the joint length of the top part is the largest;

[0103] Then, compared with the root part and the top part, the middle part is more suitable for making bamboo chopsticks.

[0104] Based on the bamboo joint density and the joint length, the whole bamboo is cut into a top segment, a middle segment and a root segment, and the top segment, the middle segment and the root segment are processed to obtain sawn-off materials, and the sawn-off materials include top strips, middle strips and root strips.

[0105] It is worth noting that based on the limitation of equipment processing, the length of the distance of the top strips, the middle strips and the root strips does not exceed 1.6m, and when processing the top segment, the middle segment and the root segment, in order to ensure the flatness of the cut, the thickness of the waste material after cutting is required to be not less than 0.5cm.

[0106] The bamboo top strip, bamboo middle strip, and bamboo root strip are cut to obtain the five kinds of bamboo chopsticks, i.e., the joint-free bamboo chopstick, the left joint-in-order bamboo chopstick, the right joint-in-order bamboo chopstick, the middle joint bamboo chopstick, and the joint-disorder bamboo chopstick. In the left joint-in-order bamboo chopstick, the bamboo joints are inclined to the left end of the bamboo chopstick, in the right joint-in-order bamboo chopstick, the bamboo joints are inclined to the right end of the bamboo chopstick, and in the middle joint bamboo chopstick, the bamboo joints are arranged in the middle part of the bamboo chopstick. In the joint-disorder bamboo chopstick, the bamboo joints are randomly distributed (there can be multiple bamboo joints).

[0107] In order to improve the appearance of the bamboo chopstick and thus the value of the bamboo chopstick, the distance limit of the bamboo joint is set. The distance limit is that the bamboo joint in the left joint-in-order bamboo chopstick must be within dcm from the left end of the bamboo chopstick, the bamboo joint in the right joint-in-order bamboo chopstick must be within dcm from the right end of the bamboo chopstick, and the bamboo joint in the middle joint bamboo chopstick must be within d / 2cm from the center of the bamboo chopstick.

[0108] Since the bamboo joints of the bamboo root strip are relatively dense, the length of the cut bamboo chopstick is set. In this embodiment, the length of the cut bamboo chopstick is usually set to 24cm, so the optimal bamboo chopstick cut from the bamboo root strip is usually the left joint-in-order bamboo chopstick or the right joint-in-order bamboo chopstick of the first segment, and the joint-disorder bamboo chopstick, which has a length requirement of 18cm-30cm, is also included. Thus, only sequential cutting is required.

[0109] According to the length of the bamboo joint of the bamboo middle strip, the bamboo middle strip is cut in accordance with the value priority rule, the joint-free priority rule, and the even number priority rule.

[0110] It can be understood that, based on the scheme of this embodiment, the length of the cut bamboo chopstick is controlled to be as close to 24cm as possible during the cutting of the bamboo middle strip. Based on this, in order to maximize the value, the joint-free bamboo chopstick is cut first, and the remaining length is ensured to be between 18cm and 30cm. Finally, the even number is cut. For example, if a bamboo middle strip is cut, and 5 pairs of bamboo chopsticks can be cut, then 5 pairs of bamboo chopsticks are produced. If 4.5 pairs of bamboo chopsticks are cut, 4 pairs of 24cm joint-free bamboo chopsticks are cut first. If the bamboo middle strip cannot be cut into joint-free bamboo chopsticks, the remaining length can be used to cut bamboo chopsticks with a length greater than 24cm. It should be noted that, during the cutting of the bamboo middle strip, the joint-disorder bamboo chopstick is avoided as much as possible.

[0111] Similarly, according to the length of the bamboo joint of the bamboo top strip, the value priority rule and the even number priority rule are followed.

[0112] Based on the adaptive cutting rule in step S02, the value calculation formula of any one of the bamboo top strip, or the bamboo middle strip, or the bamboo root strip is:

[0113]

[0114] wherein, is the total value of the current sawn-off material 、 、 and is the value of each bamboo chopstick, is the serial number of the bamboo chopstick cut by sawing;

[0115] The value calculation formula of each bamboo chopstick is:

[0116]

[0117] wherein, is the basic value of the bamboo chopstick, is an adaptive adjustment of the scarcity coefficient based on the position of the node, is a reduction coefficient based on the number of nodes; the scarcity coefficient is set based on the position of the node on the bamboo chopstick, and it is worth noting that when the bamboo chopstick is a non-noded bamboo chopstick, the scarcity coefficient is the largest, with a value of 1, and the scarcity coefficients of the left and right straight node bamboo chopsticks are less than 1 and greater than the scarcity coefficient of the middle node bamboo chopstick, wherein the scarcity coefficient of the random node bamboo chopstick is the smallest.

[0118] The basic value of the bamboo chopstick is calculated by the formula:

[0119]

[0120] wherein, is the basic value proportion calculation coefficient, is the length of the bamboo chopstick.

[0121] In summary, according to the bamboo chopstick segmentation linear programming system proposed by the present application, according to the node density and internode length of the whole bamboo, the whole bamboo is sawn into three sections and processed into corresponding bamboo strips; and based on the convenience of use and the beauty, the position of the node on the bamboo chopstick is set, and adaptive cutting rules are set for different types of bamboo strips according to the distance limit of the node, so as to maximize the economic effect; finally, the value of each bamboo chopstick is calculated according to the length, node position and number of bamboo chopsticks and other influencing factors, and the value of the bamboo strip is finally calculated. The present application uses the distance limit of the node on the bamboo chopstick to set adaptive cutting rules to replace the traditional direct cutting method, which improves the beauty of the bamboo chopstick, and thus improves the selling value of the bamboo chopstick and increases the revenue.
