Description

Technical Field

[0001] This invention relates to the field of bamboo curtain processing technology, specifically to a bamboo strip weaving curtain production line and production method. Background Technology

[0002] Bamboo blinds are sliding blinds made of woven bamboo strips. The processing first involves splitting the bamboo strips into wefts; then, these wefts are woven into a blind. Current bamboo blind processing techniques have the following drawbacks:

[0003] 1. In the bamboo splitting process, only two bamboo strips can be split at a time, resulting in low production efficiency and large space occupation; without a stable and reliable bamboo pressing mechanism, the bamboo is easily vibrated and shaken during the splitting process, affecting the surface quality of the split bamboo strips; the produced bamboo strips are piled up in a mess, resulting in low levels of continuous and automated production.

[0004] 2. The bamboo strips have uneven thickness and are stacked haphazardly at different widths, resulting in uneven thickness and inconsistent width in the woven bamboo curtain, causing a large difference in width between the left and right sides.

[0005] Therefore, it is necessary to provide a new process to solve the above-mentioned technical problems. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a bamboo strip weaving curtain production line and production method, which can realize continuous automated operation and improve production efficiency; at the same time, it improves the surface quality of split bamboo strips, and the woven bamboo curtain has uniform thickness and small difference in width between the left and right sides.

[0007] The first aspect of this invention is to provide a bamboo strip weaving curtain production line, the technical solution of which is:

[0014] Furthermore, the width of the support block is greater than the width of one bamboo strip, but less than the width of two bamboo strips;

[0015] The first image sensor is used to acquire images of both ends of each bamboo strip and calculate its edge size and area. The areas of both ends of each bamboo strip are denoted as SAi and SBi (i=1,2,3,4...), and the areas of both ends of each bamboo strip are compared.

[0016] When the area SAi at both ends of the i-th bamboo strip is greater than SBi, the flipping device is controlled to flip the (i+1)-th bamboo strip by 180° or not flip it, so that the area at both ends of the (i+1)-th bamboo strip satisfies SA(i+1) < SB(i+1).

[0017] When the area SAi at both ends of the i-th bamboo strip is less than SBi, the flipping device is controlled to flip the (i+1)-th bamboo strip by 180° or not flip it, so that the area at both ends of the (i+1)-th bamboo strip satisfies SA(i+1)>SB(i+1).

[0018] The flipping device includes a telescopic cylinder and a rotating gripper connected to the end of the telescopic cylinder.

[0019] Furthermore, the bamboo strip splitting mechanism includes multiple sets of conveying rollers for conveying bamboo strips arranged at intervals, pressure rollers corresponding to the discharge end of each set of conveying rollers, and multiple sets of splitting cutters distributed at intervals with working surfaces not on the same horizontal plane. Each set of conveying rollers includes a first conveying roller and a second conveying roller arranged symmetrically. The multiple sets of splitting cutters simultaneously split the bamboo strips into multiple bamboo strips of equal thickness.

[0020] Furthermore, the pressure roller is disposed on one side of the first conveying roller to press the surface of the first bamboo strip formed by splitting, and the diameter of the pressure roller is smaller than the diameter of the first conveying roller / second conveying roller; the splitting cutter is located between the first conveying roller and the second conveying roller, and the spacing between two adjacent sets of splitting cutters in the bamboo strip thickness direction is adjusted according to the thickness of the bamboo strip.

[0021] Furthermore, the bamboo strip feeding mechanism includes a conveyor belt, a bamboo strip sorting device located above the conveyor belt, adjusting blocks located on both sides of the conveyor belt for aligning the bamboo strips, a second photoelectric sensor for detecting whether the bamboo strips are in place, a stop block located above the conveyor belt, a second image sensor for acquiring images of both ends of the bamboo strips and calculating their width and thickness, and a gripping device located at the end of the conveyor belt for gripping defective bamboo strips, wherein the length direction of the bamboo strips is perpendicular to the conveying direction of the conveyor belt.

[0022] Furthermore, the bamboo strip sorting device includes a slot formed by an upper pressure plate and a lower pressure plate, a third photoelectric sensor located in the slot for detecting whether the bamboo strip is in place, a drive cylinder located in the slot for pushing the bamboo strip to the conveyor belt, and an elastic roller located on the upper pressure plate and at the discharge end of the slot for rolling the bamboo strip. The bamboo strips are stacked together in the slot, and the stacking direction is consistent with the conveying direction of the conveyor belt. The distance between the upper pressure plate and the lower pressure plate is greater than the width of the bamboo strip.

[0023] A second aspect of the present invention is to provide a method for producing bamboo strip woven curtains, comprising the following steps:

[0024] Step S1: Provide a bamboo strip feeding mechanism, which feeds bamboo strips alternately according to their large and small ends;

[0025] Step S2: Provide a bamboo strip splitting mechanism. The bamboo strip feeding mechanism conveys bamboo strips to the bamboo strip splitting mechanism. During the bamboo strip conveying process, the bamboo strip splitting mechanism simultaneously splits the bamboo strips into multiple bamboo strips of equal thickness.

[0026] Step S3: Provide a curtain feeding mechanism. The split bamboo strips are transported to the curtain feeding mechanism. The curtain conveying mechanism transports bamboo strips with the required thickness and cumulative width to the curtain weaving mechanism and transfers unqualified bamboo strips to the waste area.

[0027] Step S4: Provide a weaving mechanism to weave bamboo strips into a bamboo curtain.

[0028] Further, in step S1, the bamboo strip feeding mechanism includes: two feeding chains driven synchronously by a driving device and arranged in a vertical direction; a support block on the feeding chain for supporting the bamboo strips; a first image sensor on both sides of the feeding chain for collecting the dimensions of the two ends of the bamboo strips; a flipping device between the two feeding chains for flipping the bamboo strips; a conveying trough below the feeding chain for receiving the bamboo strips conveyed by the feeding chain; a first photoelectric sensor for detecting whether the bamboo strips are in place; an adjusting cylinder on one side of the conveying trough for adjusting the position of the bamboo strips; and a feeding cylinder on one end of the conveying trough for pushing the bamboo strips to the bamboo strip splitting station.

[0029] The bamboo strip feeding mechanism feeds bamboo strips alternately according to their large and small ends, including the following steps:

[0030] In step S11, the drive device moves the discharge chain, and the support block moves the bamboo strips upward in an orderly manner from the bamboo strip bin.

[0031] Step S12: The first image sensor acquires images of both ends of each bamboo strip during the transportation process, calculates the edge size and area of ​​both ends based on the images, and records the areas of both ends of each bamboo strip as SAi and SBi (i=1,2,3,4...). The areas of both ends of each bamboo strip are compared to determine the size of the bamboo strip.

[0032] Step S13: When the area SAi at both ends of the i-th bamboo strip is greater than SBi, control the flipping device to flip the (i+1)-th bamboo strip by 180° or not flip it, so that the area at both ends of the (i+1)-th bamboo strip satisfies SA(i+1) < SB(i+1).

[0033] When the area SAi at both ends of the i-th bamboo strip is less than SBi, the flipping device is controlled to flip the (i+1)-th bamboo strip by 180° or not flip it, so that the area at both ends of the (i+1)-th bamboo strip satisfies SA(i+1)>SB(i+1).

[0034] In step S14, the bamboo strips are conveyed to the bottom of the discharge chain and fall into the conveying trough. When the first photoelectric sensor detects that there are bamboo strips in the conveying trough, it controls the adjusting cylinder to extend and push the bamboo strips to the position opposite to the feeding cylinder. After the adjusting cylinder pushes the bamboo strips to the set position, the adjusting cylinder retracts.

[0035] Step S15: The feeding cylinder extends to push the bamboo strips to the bamboo strip splitting mechanism.

[0036] Step S16: Repeat steps S14-S15, feeding the bamboo strips alternately according to their large and small ends.

[0037] Further, in step S2, the bamboo strip splitting mechanism includes multiple sets of conveying rollers for conveying bamboo strips arranged at intervals, pressure rollers corresponding to the discharge end of each set of conveying rollers, and multiple sets of splitting cutters that are distributed at intervals and whose working surfaces are not on the same horizontal plane. Each set of conveying rollers includes a first conveying roller and a second conveying roller arranged symmetrically.

[0038] The pressure roller is positioned on one side of the first conveying roller to press the surface of the first bamboo strip formed by splitting, and the diameter of the pressure roller is smaller than the diameter of the first conveying roller / second conveying roller; the splitting cutter is located between the first conveying roller and the second conveying roller, and the spacing between two adjacent sets of splitting cutters in the bamboo strip thickness direction is adjusted according to the thickness of the bamboo strip;

[0039] The bamboo strip splitting mechanism simultaneously splits the bamboo strips into multiple bamboo strips of equal thickness during the bamboo strip conveying process, including the following steps:

[0040] In step S21, the bamboo strips are conveyed forward under the frictional force of the first and second conveying rollers;

[0041] Step S22: When the front end of the bamboo strip reaches the position of the first set of splitting cutters, the corresponding splitting cutter splits the bamboo strip for the first time to form the first bamboo strip; the pressure roller corresponding to the first set of conveying rollers presses the split bamboo strip, and the bamboo strip moves with the remaining bamboo strip to the next set of first and second conveying rollers.

[0042] Step S23: When the front end of the bamboo strip reaches the position of the second set of splitting tools, the corresponding splitting tool will split the bamboo strip a second time to form the second bamboo strip.

[0043] In step S24, the bamboo strips pass through multiple sets of splitting knives along the conveying direction until they are split into multiple bamboo strips of equal thickness.

[0044] Further, in step S3, the woven curtain feeding mechanism includes a conveyor belt, a bamboo strip sorting device located above the conveyor belt, adjusting blocks located on both sides of the conveyor belt for adjusting the bamboo strips in the width direction, a second photoelectric sensor for detecting whether the bamboo strips are in place, a stop block located above the conveyor belt, a second image sensor for acquiring images of both ends of the bamboo strips and calculating their width and thickness, and a gripping device located at the end of the conveyor belt for gripping defective bamboo strips, wherein the length direction of the bamboo strips is perpendicular to the conveying direction of the conveyor belt;

[0045] The bamboo strip sorting device includes a slot formed by an upper pressure plate and a lower pressure plate, a third photoelectric sensor located in the slot for detecting whether the bamboo strips are in place, a drive cylinder located in the slot for pushing the bamboo strips to the conveyor belt, and an elastic roller located on the upper pressure plate at the discharge end of the slot for rolling the bamboo strips. The bamboo strips are stacked together in the slot, and the stacking direction is consistent with the conveying direction of the conveyor belt. The distance between the upper pressure plate and the lower pressure plate is greater than the width of the bamboo strips.

[0046] The weaving curtain conveying mechanism transports bamboo strips that meet the width and thickness requirements to the weaving curtain mechanism, and transfers unqualified bamboo strips to the waste area, including the following steps:

[0047] Step S31: The bamboo strips split by the bamboo strip splitting mechanism are transported into the slot, and the bamboo strips split from a bamboo strip are stacked in the slot, and the stacking direction of the bamboo strips is consistent with the conveying direction of the conveyor belt.

[0048] Step S32: When the third photoelectric sensor detects that all the bamboo strips have entered the slot, the drive cylinder is activated to push the bamboo strips forward.

[0049] Step S33: When the bamboo strips reach the bottom of the elastic roller, the elastic roller presses the bamboo strips, causing the adjacent bamboo strips stacked together to be separated by different pressures; when the foremost single bamboo strip is pushed out of the slot, it is no longer bound by pressure and falls onto the conveyor belt. At this time, the width direction of the bamboo strips is consistent with the conveying direction of the conveyor belt.

[0050] Step S34: When the bamboo strip moves to the position of the adjusting block, the position of the bamboo strip is adjusted by the adjusting block to make it aligned.

[0051] Step S35: When the second photoelectric sensor detects that the bamboo strip has moved to the set position, the transmission belt is controlled to stop working, and the stop block is controlled to move down to block the current bamboo strip from moving forward.

[0052] Step S34: The second image sensor captures images of both ends of the current bamboo strip, calculates the width and thickness of both ends respectively, counts the number of bamboo strips, calculates the width of both ends of the bamboo strip by superposition, and compares the thickness of both ends of the current bamboo strip.

[0053] In step S35, the stop block moves upward, and the bamboo strip continues to move forward. When the thickness difference between the two ends of the bamboo strip is greater than the value of h, the gripping device grips the unqualified bamboo strip to the waste area, and the bamboo strip that meets the thickness requirements is transported to the weaving mechanism, where h = 0.1-0.5 mm.

[0054] Step S36: When the cumulative width of the bamboo strips at both ends reaches the design requirements of the bamboo curtain, stop feeding the bamboo strips to the curtain weaving mechanism.

[0055] Compared with the prior art, the bamboo strip weaving curtain production line and production method provided by the present invention have the following advantages:

[0056] I. The bamboo strip weaving curtain production line and method provided by this invention involves feeding bamboo strips alternately at their large and small ends using a bamboo strip feeding mechanism, simultaneously dividing the bamboo strips into multiple equal pieces using a bamboo strip splitting mechanism, and inspecting the split bamboo strips using a curtain feeding mechanism to transport bamboo strips with cumulative width and thickness that meet the requirements to the curtain weaving mechanism. Throughout the production process, because the bamboo strips are fed alternately at their large and small ends, the large and small ends of the bamboo strips transported to the curtain feeding mechanism are arranged in a regular pattern, resulting in a woven bamboo curtain with approximately equal width on both sides. The thickness of the split bamboo strips is inspected on the curtain feeding mechanism, and defective bamboo strips with inconsistent thickness at both ends are picked up and moved to the waste area, thus ensuring a uniform thickness for the woven bamboo curtain.

[0069] Please refer to the following: Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of the bamboo strip weaving curtain production line of the present invention. Figure 2 Figure 1 A schematic diagram of some structures in the bamboo strip weaving production line of the present invention. The bamboo strip weaving production line of the present invention includes a bamboo strip feeding mechanism 1, a bamboo strip splitting mechanism 2, a weaving curtain feeding mechanism 3, a weaving curtain mechanism 4, and a control device 5 for controlling the operation of each mechanism, arranged sequentially and connected to each other. The bamboo strip feeding mechanism 1 is used to feed bamboo strips alternately according to their end area, with the bamboo strip splitting mechanism 2 used to simultaneously split the bamboo strips into multiple bamboo strips of equal thickness. The weaving curtain feeding mechanism 3 is used to transport bamboo strips with the required width and thickness to the weaving curtain mechanism. The weaving curtain mechanism 4 is used to weave the bamboo strips into a curtain to form a bamboo curtain.

[0070] Please refer to the following: Figure 3 ,yes Figure 2 The diagram shows a different angle of the bamboo strip feeding mechanism in the bamboo weaving curtain production line. In this invention, the bamboo strip feeding mechanism 1 includes two feeding chains 11 driven synchronously by a driving device and arranged vertically, a support block 12 on the feeding chains for supporting bamboo strips 100, a first image sensor 13 on both sides of the feeding chains for collecting images of the two ends of the bamboo strips, a flipping device 14 between the two feeding chains for flipping the bamboo strips, a conveying trough 15 below the feeding chains for receiving the bamboo strips conveyed by the feeding chains, a first photoelectric sensor 16 for detecting whether the bamboo strips are in place, an adjusting cylinder 17 on one side of the conveying trough for adjusting the position of the bamboo strips, and a feeding cylinder 18 on one end of the conveying trough for pushing the bamboo strips to the bamboo strip splitting station.

[0071] The feeding chain 11 is positioned vertically, driving the bamboo strips to move upwards and downwards in the vertical direction. The support block 12 is used to support only one bamboo strip; therefore, its width is greater than the width of one bamboo strip but less than the width of two bamboo strips. The support blocks 12 are symmetrically distributed on the two feeding chains, making the movement of the bamboo strips smoother. In this embodiment, the feeding chain 11 moves, relying on the support blocks to orderly drive the bamboo strips upwards from the bamboo strip hopper.

[0072] There are two first image sensors 13, which are used to acquire images of both ends of the bamboo strip and calculate the edge dimensions and areas of both ends based on the images. The areas of both ends of each bamboo strip are denoted as SAi and SBi (i=1,2,3,4...). The areas of both ends of each bamboo strip are compared to determine the larger end of the bamboo strip. If SAi > SBi, the SAi end is the larger end and the SBi end is the smaller end. In this embodiment, SAi can be defined as the left end of the bamboo strip and SBi can be defined as the right end of the bamboo strip.

[0073] When the area SAi at both ends of the i-th bamboo strip is greater than SBi, the flipping device is controlled to flip the (i+1)-th bamboo strip by 180° or not flip it, so that the area at both ends of the (i+1)-th bamboo strip satisfies SA(i+1) < SB(i+1).

[0074] When the area SAi at both ends of the i-th bamboo strip is less than SBi, the flipping device is controlled to flip the (i+1)-th bamboo strip by 180° or not flip it, so that the area at both ends of the (i+1)-th bamboo strip satisfies SA(i+1)>SB(i+1).

[0075] The bamboo strips are flipped using a flipping device to achieve alternating feeding of the large and small ends of the bamboo strips. The flipping device 14 includes a telescopic cylinder 141 and a rotating gripper 142 connected to the end of the telescopic cylinder. When the flipping device 14 needs to perform a flipping action, firstly, the rotating gripper is controlled to clamp the corresponding bamboo strip, then the telescopic cylinder 141 is controlled to extend, causing the bamboo strip to detach from the support block. Next, the rotating gripper is controlled to rotate 180°, changing the large and small ends of the bamboo strip. Finally, the telescopic cylinder is controlled to retract again, placing the bamboo strip on the corresponding support block.

[0076] In this embodiment, both the first image sensor 13 and the flipping device 14 are located at the top of the discharge chain, making the operation of the flipping device more convenient.

[0077] The conveying trough 15 is located below the discharge chain, with one end connected to the bamboo strip splitting mechanism, used to transport bamboo strips to the bamboo strip splitting mechanism. The bamboo strip falls into the conveying trough 15, its length direction being the length direction of the conveying trough. When the first photoelectric sensor 16 detects that a bamboo strip has fallen into the conveying trough, it controls the adjusting cylinder 17 to extend, pushing the bamboo strip to one side of the conveying trough, opposite the feeding cylinder; after the adjusting cylinder pushes the bamboo strip to the set position, the adjusting cylinder retracts, at which point the feeding cylinder 18 actuates. The feeding cylinder 18 extends, abuts against the end of the bamboo strip, and pushes the bamboo strip to the bamboo strip splitting mechanism.

[0078] Please refer to the following: Figure 4 ,yes Figure 2 The diagram shown is a structural schematic of the bamboo strip splitting mechanism in a bamboo weaving production line from another angle. This diagram illustrates the positional relationship between the splitting cutter and the conveyor rollers. Figure 2In the bamboo strip weaving production line shown, the bamboo strip splitting mechanism rotates 90 degrees. Specifically, the bamboo strip splitting mechanism 2 includes multiple sets of conveying rollers 21 spaced apart for conveying bamboo strips, pressure rollers 22 corresponding to the discharge end of each set of conveying rollers, and multiple sets of splitting cutters 23 spaced apart with their working surfaces not on the same horizontal plane. Specifically, each set of conveying rollers 21 includes a first conveying roller 211 and a second conveying roller 212 symmetrically arranged. The bamboo strips are conveyed forward under the friction of the first conveying roller 211 and the second conveying roller 212. The multiple sets of conveying rollers 21 not only realize the conveying of bamboo strips, but also satisfy the requirement of pressing the bamboo strips during the conveying process, fixing the bamboo strips, reducing the vibration amplitude during bamboo strip splitting, thereby improving the surface quality of the split bamboo strips. In this embodiment, the first conveying roller and the second conveying roller are symmetrically distributed from left to right (e.g., Figure 2 As shown), the splitting tool is set in a vertical direction. Figure 2 (No schematic diagram of the corresponding splitting cutter is provided). As an alternative, the first and second conveying rollers can also be symmetrically distributed vertically, in which case the splitting cutter is set horizontally. It should be noted that the working surface of the splitting cutter refers to the cutting surface on which it splits the bamboo strips.

[0079] The pressure roller 22 is located at the discharge end of the conveying roller and is used to press the split bamboo strips. Therefore, the pressure roller is correspondingly located on one side of the discharge end of the first conveying roller. In this embodiment, the diameter of the pressure roller is smaller than the diameter of the first conveying roller / second conveying roller.

[0080] Multiple sets of splitting cutters 23 simultaneously split bamboo strips into multiple bamboo strips of equal thickness. Specifically, the splitting cutters are located between the first and second conveying rollers, and the working surfaces of the multiple sets of splitting cutters are not on the same horizontal plane, thereby splitting the bamboo strips into multiple bamboo strips. The spacing between two adjacent sets of splitting cutters in the bamboo strip thickness direction is adjusted according to the thickness of the bamboo strips, such as being set to 0.5-4mm. In this embodiment, each set of conveying rollers corresponds to one set of splitting cutters, and the splitting cutters are located between the first conveying roller 211 and the pressure roller 22. When the front end of the bamboo strip reaches the position of the first set of splitting cutters, the corresponding splitting cutter splits the bamboo strip for the first time, forming the first bamboo strip; the pressure roller corresponding to the first set of conveying rollers presses the split bamboo strip tightly, and the bamboo strip moves together with the remaining bamboo strip to the next set between the first and second conveying rollers; when the front end of the bamboo strip reaches the position of the second set of splitting cutters, the corresponding splitting cutter splits the bamboo strip for the second time, forming the second bamboo strip; the bamboo strip passes through multiple sets of splitting cutters in sequence along the conveying direction until the bamboo strip is split into multiple bamboo strips of equal thickness.

[0081] In this invention, the bamboo strip splitting mechanism 2, compared with the traditional splitting method, not only ensures the surface quality of the split bamboo strips, but also enables the bamboo strips to be split into multiple bamboo strips simultaneously, improving production efficiency, producing bamboo strips with uniform thickness, and requiring less production space.

[0082] After being split, the bamboo strips are conveyed to the weaving curtain feeding mechanism by the conveyor rollers, and multiple bamboo strips split from a single bamboo strip are stacked together for conveying. When the bamboo strips are conveyed to the weaving curtain feeding mechanism, the length direction of the bamboo strips 200 is perpendicular to the conveying direction of the weaving curtain feeding mechanism.

[0083] Please refer to the following: Figure 5 ,yes Figure 2 The diagram shows a schematic of the feeding mechanism in a bamboo weaving production line. The feeding mechanism 3 includes a conveyor belt 31, a bamboo strip sorting device 32 located above the conveyor belt, adjusting blocks 33 on both sides of the conveyor belt 31 for aligning the bamboo strips, a second photoelectric sensor (not shown) for detecting whether the bamboo strips are in position, a stop block 35 located above the conveyor belt, a second image sensor 36 for acquiring images of both ends of the bamboo strips and calculating their width and thickness, and a gripping device 37 located at the end of the conveyor belt for grabbing defective bamboo strips. The bamboo strip sorting device 32, adjusting blocks 33, stop blocks 35, and gripping device 37 are arranged sequentially along the conveying direction of the conveyor belt.

[0084] Please refer to the following: Figure 6 ,yes Figure 5 The diagram shows the structure of the bamboo strip sorting device in the curtain feeding mechanism. In this embodiment, the bamboo strip sorting device 32 includes a slot 323 formed by an upper pressure plate 321 and a lower pressure plate 322, a third photoelectric sensor (not shown) located in the slot for detecting whether the bamboo strips are in place, a drive cylinder 324 located in the slot for pushing the bamboo strips to the conveyor belt, and an elastic roller 325 located on the upper pressure plate and at the discharge end of the slot for rolling the bamboo strips (e.g., ...). Figure 7 As shown), the bamboo strips are stacked together in the slot (as shown). Figure 8 As shown), the stacking direction is consistent with the conveyor belt's conveying direction, and the distance between the upper pressure plate 321 and the lower pressure plate 322 is greater than the width of the bamboo strips.

[0085] A bamboo strip is split into bamboo strips by a bamboo splitting mechanism and then conveyed layer by layer into a slot. At this point, the bamboo strips are tightly packed together. Once the third photoelectric sensor detects that all the bamboo strips have entered the slot, it controls the drive cylinder to actuate, slowly pushing the bamboo strips forward. When the bamboo strips reach below the elastic roller, the elastic roller 325 presses down on the bamboo strips, keeping them vertical and separating adjacent strips by applying different pressures. When the foremost bamboo strip is pushed out of the slot, it is no longer constrained by pressure and falls onto the conveyor belt. At this point, the width of the bamboo strip is aligned with the conveyor belt's transport direction. The other bamboo strips remain vertical under the pressure of the elastic roller, ensuring that adjacent strips do not overlap and maintain a certain distance. Once all the bamboo strips have been pushed out of the slot, the drive cylinder quickly resets, ready to carry the next batch of bamboo strips.

[0086] In this embodiment, the elastic roller can also be replaced by a ball bearing; the drive cylinder can be an electric drive cylinder or a hydraulic drive cylinder. In order to ensure the stability of the drive cylinder pushing the bamboo strip forward, two drive cylinders are set and distributed at both ends of the slot axis.

[0087] In this embodiment, the distance between the upper pressure plate 321 and the lower pressure plate 322 is 2-5mm greater than the width of the bamboo strip, and the elastic roller is located in the gap between the bamboo strip and the upper pressure plate.

[0088] Adjusting blocks 33 are located on both sides of the transmission belt to adjust the position of the bamboo strips, ensuring they are parallel and aligned along their length. In this embodiment, the adjusting blocks 33 are inclined blocks. When the bamboo strips are conveyed to the corresponding positions, the adjusting blocks 33 are controlled to move closer to both ends of the bamboo strips to adjust their positions and align them.

[0089] Stop blocks 35 are used to prevent the bamboo strips from moving forward. In this embodiment, there are two stop blocks 35, located on the same straight line. When preventing the current bamboo strip from moving forward, it ensures that the length direction of the bamboo strip is always perpendicular to the transmission direction. A second photoelectric sensor is mounted on the stop block 35; correspondingly, there are also two second photoelectric sensors. When the second photoelectric sensor detects that the bamboo strip has moved to a set position, the control device controls the transmission belt to stop working and controls the stop block to move downwards to block the current bamboo strip from moving forward. At this time, the second image sensor 36 acquires images of both ends of the current bamboo strip and uses image processing techniques such as the Canyon algorithm to calculate the width and thickness of the bamboo strip at both ends. The second image sensor also counts and statistically analyzes the bamboo strips that have passed through, superimposes the widths of the counted bamboo strips at both ends, and compares the thicknesses of the current bamboo strip at both ends. By superimposing the widths of the two ends of the statistically recorded bamboo strips, it can be determined whether the cumulative width of the bamboo strips fed to the weaving mechanism meets the requirements based on the specifications of the processed bamboo curtain. If the requirements are met, bamboo strips can be temporarily fed into the weaving mechanism according to the program settings. By comparing the thicknesses of the two ends of the current bamboo strips, the uniformity of the bamboo strip thickness can be detected. Bamboo strips with a thickness difference greater than a set value at both ends are identified as defective bamboo strips. Based on the detection results, the gripping device 36 is controlled to grip the defective bamboo strips and move them to the waste area. In this embodiment, bamboo strips with a thickness difference greater than h at both ends are identified as defective bamboo strips, where h = 0.1-0.5 mm.

[0090] The weaving mechanism 4 can be any commercially available equipment that can weave bamboo curtains; its specific structure will not be described in detail here.

[0091] Based on the structure of the bamboo strip weaving curtain production line described above, the present invention also provides a method for producing bamboo strip weaving curtains.

[0092] A method for producing bamboo strip woven curtains includes the following steps:

[0093] Step S1: The bamboo strip feeding mechanism feeds bamboo strips alternately according to their large and small ends, specifically including the following steps:

[0094] In step S11, the drive device moves the discharge chain, and the support block moves the bamboo strips upward in an orderly manner from the bamboo strip bin.

[0095] Step S12: The first image sensor acquires images of both ends of each bamboo strip during the transportation process, calculates the edge size and area of ​​both ends based on the images, and records the areas of both ends of each bamboo strip as SAi and SBi (i=1,2,3,4...). The areas of both ends of each bamboo strip are compared to determine the size of the bamboo strip.

[0096] For example, when SAi > SBi, the SAi end is the big end and the SBi end is the small end.

[0097] Step S13: When the area SAi at both ends of the i-th bamboo strip is greater than SBi, control the flipping device to flip the (i+1)-th bamboo strip by 180° or not flip it, so that the area at both ends of the (i+1)-th bamboo strip satisfies SA(i+1) < SB(i+1).

[0098] When the area SAi at both ends of the i-th bamboo strip is less than SBi, the flipping device is controlled to flip the (i+1)-th bamboo strip by 180° or not flip it, so that the area at both ends of the (i+1)-th bamboo strip satisfies SA(i+1)>SB(i+1).

[0099] In step S14, the bamboo strips are conveyed to the bottom of the discharge chain and fall into the conveying trough. When the first photoelectric sensor detects that there are bamboo strips in the conveying trough, the adjusting cylinder is controlled to extend and push the bamboo strips to the position opposite to the feeding cylinder. After the adjusting cylinder pushes the bamboo strips to the set position, the adjusting cylinder retracts.

[0100] Step S15: The feeding cylinder extends and pushes the bamboo strips to the bamboo strip splitting mechanism.

[0101] Step S16: Repeat steps S14-S15, feeding the bamboo strips alternately according to their large and small ends.

[0102] Step S2: The bamboo strip feeding mechanism conveys the bamboo strips to the bamboo strip splitting mechanism. During the bamboo strip conveying process, the bamboo strip splitting mechanism simultaneously splits the bamboo strips into multiple bamboo strips of equal thickness. Specifically, this includes the following steps:

[0103] In step S21, the bamboo strips are conveyed forward under the frictional force of the first and second conveying rollers;

[0104] Step S22: When the front end of the bamboo strip reaches the position of the first set of splitting cutters, the corresponding splitting cutter splits the bamboo strip for the first time to form the first bamboo strip; the pressure roller corresponding to the first set of conveying rollers presses the split bamboo strip, and the bamboo strip moves with the remaining bamboo strip to the next set of first and second conveying rollers.

[0105] Step S23: When the front end of the bamboo strip reaches the position of the second set of splitting tools, the corresponding splitting tool will split the bamboo strip a second time to form the second bamboo strip.

[0106] In step S24, the bamboo strips pass through multiple sets of splitting knives along the conveying direction until they are split into multiple bamboo strips of equal thickness.

[0107] Step S3: The split bamboo strips are conveyed to the weaving curtain feeding mechanism. The weaving curtain conveying mechanism transports bamboo strips with the required width and thickness to the weaving curtain mechanism and transfers unqualified bamboo strips to the waste area; specifically, it includes the following steps:

[0108] Step S31: The bamboo strips split by the bamboo strip splitting mechanism are transported into the slot, and the bamboo strips split from a bamboo strip are stacked in the slot, and the stacking direction of the bamboo strips is consistent with the conveying direction of the conveyor belt.

[0109] Step S32: When the third photoelectric sensor detects that all the bamboo strips have entered the slot, the drive cylinder is activated to push the bamboo strips forward.

[0110] Step S33: When the bamboo strips reach the bottom of the elastic roller, the elastic roller presses the bamboo strips, causing the adjacent bamboo strips stacked together to be separated by different pressures; when the frontmost single bamboo strip is pushed out of the slot, it is no longer bound by pressure and falls onto the conveyor belt. At this time, the width direction of the bamboo strips is consistent with the conveying direction of the conveyor belt.

[0111] The elastic rollers ensure that adjacent bamboo strips do not overlap and maintain a certain distance. After all the bamboo strips are pushed out of the slots, the drive cylinder quickly resets and prepares to carry the next batch of bamboo strips.

[0112] Step S34: When the bamboo strip moves to the position of the adjusting block, adjust the position of the bamboo strip by adjusting the adjusting block to make it aligned;

[0113] Step S35: When the second photoelectric sensor detects that the bamboo strip has moved to the set position, the transmission belt is controlled to stop working, and the stop block is controlled to move down to block the current bamboo strip from moving forward.

[0114] Step S36: The second image sensor captures images of both ends of the current bamboo strip, calculates the width and thickness of both ends respectively, counts the number of bamboo strips, calculates the width of both ends of the bamboo strip by superposition, and compares the thickness of both ends of the current bamboo strip.

[0115] By superimposing the widths of the two ends of the statistically recorded bamboo strips, it can be determined whether the cumulative width of the bamboo strips that have been fed to the weaving mechanism meets the requirements based on the specifications and dimensions of the processed bamboo curtain. If the requirements are met, bamboo strips can be temporarily fed into the weaving mechanism according to the program settings. By comparing the thicknesses of the two ends of the current bamboo strips, the uniformity of the bamboo strip thickness can be detected, and bamboo strips with inconsistent thicknesses at both ends can be identified as defective bamboo strips.

[0116] In step S37, the stop block moves upward, and the bamboo strip continues to move forward. When the thickness difference between the two ends of the bamboo strip is greater than the value of h, the gripping device grips the unqualified bamboo strip to the waste area, and the bamboo strip that meets the thickness requirements is transported to the weaving mechanism, where h = 0.1-0.5 mm.

[0117] Step S38: When the cumulative width of the bamboo strips at both ends reaches the design requirements of the bamboo curtain, stop feeding the bamboo strips to the curtain weaving mechanism.

[0118] Step S4: The weaving mechanism weaves the bamboo strips into a bamboo curtain. The structure of the bamboo curtain is as follows... Figure 9 As shown.

[0119] The bamboo strip weaving production line and production method of the present invention, because the bamboo strips are fed alternately according to the large and small ends, the large and small ends of the bamboo strips conveyed to the weaving curtain feeding mechanism are arranged in a regular manner, so that the width of the woven bamboo curtain is equal on both sides; while in the traditional bamboo strip weaving process, the width difference between the two sides of the bamboo curtain can be as high as 20-30cm.

[0120] The bamboo strip weaving curtain production line and production method of the present invention involve performing thickness detection on the bamboo strips after splitting on the curtain feeding mechanism, so that defective bamboo strips with inconsistent thickness at both ends are picked up and sent to the waste area, thereby making the woven bamboo curtain of uniform thickness.

[0121] The embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and spirit of the present invention still fall within the protection scope of the present invention.
