[0041] Example:

[0042] See also Figures 1 to 8, the automatic bamboo strip feeding device in the preferred embodiment of the present invention is arranged on a base 9, which includes a lifting tool 1 and a workbench 8 arranged on the base 9, and a displacement assembly 2, a positioning turntable tool 3, a feeding and cutting tool 4, a feeding disc tool 5, an automatic tightening tool 6 and a discharging tool 7 arranged on the workbench 8. Among them, the feeding disc tool 5 and the automatic tightening tool 6 are correspondingly arranged on the displacement assembly 2, and are respectively used for feeding the bamboo strip disc 302 and setting the bamboo strip disc 302 in the row of the feeding disc 301. Further, the feeding and cutting tool 4 is arranged corresponding to the positioning turntable tool 3, and is used for feeding and cutting the bamboo strips on the bamboo strip disc 302, and the discharging tool 7 is arranged on the workbench 8, and is used for discharging the material from the feeding and cutting tool 4 to the next process, for example, discharging to the winding mold.

[0043] Specifically, the workbench 8 in the preferred embodiment is higher than the setting position of the base 9, and the lifting tooling 1 is set on the base 9 on one side of the workbench 8, which includes a horizontally set slider guide 101 and a vertically set lifting guide 105, and the lifting guide 105 is fixed with its bottom on the base 9 at one end of the slider guide 101.

[0044] Further, a clamp assembly is provided on the slider rail 101 for clamping and loading the bamboo strips tray. The clamp assembly includes a first clamp 102 and a second clamp 103 arranged relatively to each other. The two clamps (102, 103) can move relatively to clamp the bamboo strips tray placed between the two clamps. It is not difficult to see that the tops of the first clamp 102 and the second clamp 103 are both arranged as semicircular arc structures corresponding to the bamboo strips tray to match the shape of the bamboo strips tray. Preferably, the first clamp 102 is fixedly arranged, and the second clamp 103 can move relative to it. For example, in a preferred embodiment, a clamping component 104 is provided at the bottom of the second fixture 103 to drive the second fixture 103 to move. The clamping component 104 in the preferred embodiment can be further specifically a driving assembly consisting of a slider, a cylinder, and a polished rod. The slider is correspondingly sleeved on the polished rod and matched with the cylinder, so that the cylinder can drive the slider to reciprocate along the axial direction of the outer periphery of the polished rod, and the second fixture 103 is correspondingly provided on the slider, and can reciprocate with the slider. In order to achieve a stable setting of the second fixture 103, at least two "slider-polished rod combinations" are provided in the preferred embodiment, which are respectively provided on both sides of the bottom of the second fixture 103.

[0045] Of course, the clamping component 104 is not limited to the above-mentioned form, and it can also be preferably in other forms according to actual needs, such as a spiral screw form, as long as it can achieve relative movement between the two clamps and clamp the bamboo strips disc between the two clamps.

[0046] Furthermore, the lifting guide rail 105 is arranged on one side of the slider guide rail 101, which has a guide rail arranged vertically, and corresponding to the guide rail, there are Figure 1The shaft extension 106 shown in the figure is in the shape of a horizontally arranged rod, which is correspondingly arranged on a slider matched to the lifting guide rail 105, and is used to pass through the through hole in the middle of the bamboo strips plate. Specifically, the shaft extension 106 can reciprocate vertically in the lifting guide rail 105, and in the preferred embodiment, a sprocket 107 is arranged in the lifting guide rail 105 to realize this function, that is, the shaft extension 106 can reciprocate vertically under the action of the sprocket 107 to realize the lifting of the bamboo strips plate 302 on the base 9. Obviously, the component driving the shaft extension 106 in the lifting guide rail 105 is not only capable of being set to the sprocket 107, and it can also be preferably set to other forms according to actual needs, such as cylinder drive, gear drive, screw drive, etc.

[0047] Furthermore, a displacement assembly 2 is provided on the workbench 8 corresponding to the lifting guide rail 105, which includes an X-axis guide rail 201 and a Y-axis guide rail 202 arranged horizontally and orthogonally, and the Y-axis guide rail 202 is preferably arranged on the X-axis guide rail 201, and can reciprocate along the axial direction of the X-axis guide rail 201 on the X-axis guide rail 201. Correspondingly, at least one positioning turntable tooling 3 is provided on the workbench 8 on one side of the X-axis guide rail 201, for example, two are arranged side by side in the preferred embodiment. In fact, in the winding process of bamboo strips, since the alternating winding of axial bamboo strips and circumferential bamboo strips is often required, it is mostly necessary to respectively set the positioning turntable tooling 3 corresponding to the discharge of the axial bamboo strip disc and the circumferential bamboo strip disc, and at least two positioning turntable toolings 3 are arranged at intervals in the direction parallel to the X-axis guide rail 201.

[0048] Specifically, the positioning turntable tooling 3 in the preferred embodiment includes a base and a feed tray 301 arranged on the side of the base facing the X-axis guide rail 201. The feed tray 301 is rotatably arranged on the base, and a plurality of fixed shafts perpendicular to the disk surface are arranged at intervals on its end surface, which are used to pass through the through hole in the middle of the bamboo strip tray 302 to realize the installation of the bamboo strip tray 302 on the feed tray 301. At the same time, the feed tray 301 can rotate around the axis to ensure that the working bamboo strip tray 302 can be switched accordingly.

[0049] Furthermore, an automatic tightening fixture 6 is provided on the X-axis guide rail 201, and a tray feeding fixture 5 is provided on the Y-axis guide rail 202. The latter is used to carry the bamboo strip tray 302 lifted by the lifting fixture 1 to the corresponding positioning turntable fixture 3, and to sleeve the bamboo strip tray 302 on the fixed shaft on the feeding tray 301. The former is used to tighten and fix the bamboo strip tray sleeved on the fixed shaft to prevent the bamboo strip tray 302 from falling off the feeding tray 301.

[0050] In a preferred embodiment, the tray feeding tool 5 is as follows Figure 6 , 7As shown in , it includes a lifting bracket 502 vertically arranged above the Y-axis guide rail 202, and the lifting bracket 502 can reciprocate along the Y-axis direction on the Y-axis guide rail 202 to make the tray delivery tooling 5 close to or away from the feeding tray 301. Further, a tray delivery bracket 501 is arranged on the lifting bracket 502, and the tray delivery bracket 501 can slide back and forth vertically on the lifting bracket 502 to adjust the height of the tray delivery. At the same time, a third clamp 503 and a fourth clamp 504 are relatively arranged on the tray delivery bracket 501, and the arrangement of the two clamps is similar to that of the first clamp 102 and the second clamp 103, that is, the above two clamps (503, 504) can move relative to each other to realize the bearing and clamping of the bamboo strip tray 302. Preferably, the third clamp 503 is fixedly arranged on the tray feeding bracket 501, and the fourth clamp 504 is movably arranged, and can approach or move away from the third clamp 503 under the action of corresponding driving components (such as a cylinder, an optical axis, and a slider assembly arranged at its bottom).

[0051] Obviously, in order to realize the process of the disc delivery tooling 5 taking the disc from the lifting tooling 1, one end of the X-axis guide rail 201 in the preferred embodiment extends out from the side of the workbench 8, and its end is facing the lifting guide rail 105, and then the Y-axis guide rail 201 on the X-axis guide rail 201 can drive the disc delivery tooling 5 to move, and realize the alignment of the disc delivery tooling 5 and the lifting guide rail 105, that is, the third clamp 503 and the fourth clamp 504 can carry the bamboo strip disc 302 lifted by the shaft extension 106, and then use the clamping of the two clamps and the movement of the lifting bracket 502 along the Y-axis to remove the bamboo strip disc 302 from the shaft extension 106, and finally send the disc to the corresponding positioning turntable tooling 3.

[0052] Furthermore, the automatic tightening tool 6 in the preferred embodiment is as follows Figure 3 , 7 As shown in , it includes a base frame 601 arranged on the X-axis guide rail 201, a support plate 602 arranged on the base frame 601, and a tightening panel 606 correspondingly arranged on the side of the support plate 602 facing the positioning turntable fixture 3. The plate surface of the tightening panel 606 is preferably arranged vertically, and it is movably matched on the support plate 602 through a plurality of optical axes 607, and can reciprocate in the horizontal direction. In a preferred embodiment, there are four optical axes 607 arranged at intervals, one end of the optical axis 607 is fixed on the end face of the tightening panel 606, and the other end passes through a corresponding horizontal through hole on the support plate 602.

[0053] Furthermore, an electric wrench 604 is provided in the middle of the tightening panel 606, the axis of which is perpendicular to the disk surface of the feed disk 301 and can move horizontally with the tightening panel 606 to tighten the end of the bamboo strip disk 302 after being sleeved on the fixed shaft, thereby reducing the workload of manual operation and improving the installation and replacement efficiency of the bamboo strip disk 302. At the same time, a tightening cylinder 603 is provided on the support plate 602 corresponding to the tightening panel 606, which is used to drive the tightening panel 606 to move horizontally. The tightening cylinder is preferably arranged horizontally, and its output shaft is matched with the support plate 602 through a bearing, and the end of the output shaft is matched and connected to the tightening panel 606.

[0054] Furthermore, a detection component 605 is provided on the tightening panel 606 corresponding to the electric wrench 604, which is used to detect whether the bamboo strip disc 302 is tightened in place; specifically, the axis of the detection component 605 is parallel to the axis of the electric wrench 604, one end of which extends outward, and after the electric wrench 604 abuts against the fixed shaft or the bamboo strip disc 302, the end can abut against the end face of the bamboo strip disc 302 to detect the reaction force of the bamboo strip disc 302 on the detection component 605, so as to judge whether the bamboo strip disc 302 is tightened in place.

[0055] Preferably, the detection component 605 in the embodiment is arranged at the end of the output shaft of the tightening cylinder 603, and the output shaft passes through the tightening panel 606, and the output shafts on both sides of the tightening panel 606 are respectively provided with springs, namely a first spring and a second spring. By detecting the shrinkage deformation of the two springs, it can be determined whether the tightening panel 606 and the electric wrench 604 have moved into place, and whether the electric wrench 604 has tightened the bamboo strip disc 302 on the fixed shaft.

[0056] Furthermore, in a preferred embodiment, a feeding and cutting tool 4 is provided on a workbench 8 below each positioning turntable tool 3 , and a discharging tool 7 is provided at the end of the workbench 8 .

[0057] Among them, the feeding cutting tool 4 is as follows Figure 5 As shown in , it includes a bracket and a first pressing roller 401 and a second pressing roller 402 arranged at both ends of the bracket, and a panel 403 arranged horizontally below the two pressing rollers; in a preferred embodiment, the panel 403 is a transmission belt. Further, a cutting assembly is arranged on the side of the first pressing roller 401 away from the second pressing roller 402, which includes a cutter 404 and a cutting platform 405 arranged below the cutter 404, and a lifting component 406 is arranged corresponding to the cutter 404, which is matched with the two ends of the cutter 404, and can drive the two ends of the cutter 404 to rise and fall vertically, so that the cutter 404 cuts the material. In a preferred embodiment, the lifting component 406 is a hydraulic cylinder or a pneumatic cylinder.

[0058] Preferably, when the cutter 404 is not working, its bottom is higher than the bottom surface of the first roller 401, and the cutting platform 405 is lower than the top surface of the panel 403. At the same time, in the preferred embodiment, one end of the first roller 401 and the second roller 402 are rotatably connected to the bracket, and the other end is correspondingly locked on the bracket, so that the two rollers can rotate around the other end after one end is unlocked, that is, for Figure 5 As for the two pressing rollers, they can be converted from a horizontal state to a vertical state after one end is unlocked, so as to facilitate the overlapping of materials in different bamboo strip trays 302.

[0059] When there are multiple bamboo strip trays 302 on the feeding tray 301, the bamboo strip trays 302 are sequentially numbered 1, 2, 3, ... n. When the bamboo strip tray 1 is ready to feed, it moves with the feeding tray 301 to the top of the panel 403. Figure 1 , 2 As shown in , at this time, the bamboo strips disc 302 is located at the lowest point on the feed disc 301, and then the bamboo strips on the No. 1 bamboo strips disc can pass from under the first pressing roller 401, and the bottom of the bamboo strips material abuts against the lower panel 403, and the bamboo strips material penetrates between the cutter 404 and the cutting platform 405, so that the cutter 404 can cut the transmitted bamboo strips material as needed. When the bamboo strips material in the No. 1 bamboo strip tray is about to be fed, the material in the No. 2 bamboo strip tray can be overlapped at the second pressure roller 402 first, at which time the lockable end of the second pressure roller 402 is not locked, and the bamboo strips material does not contact the panel 403. When the No. 1 bamboo strip tray is about to finish feeding, the end of the second pressure roller 401 is locked, so that the bamboo strips material on the No. 2 bamboo strip tray contacts the panel 403. With the movement of the panel 403, the material in the No. 2 bamboo strip tray begins to feed from the first pressure roller 401 side first, and passes under the first pressure roller 401. Thereafter, the feeding tray 301 can start to rotate, so that the No. 2 bamboo strip tray starts to rotate toward the position of the No. 1 bamboo strip tray, and at the same time, the second pressure roller 402 is opened, so that the bamboo strips material in the No. 2 bamboo strip tray no longer passes under the second pressure roller 402. When the No. 2 bamboo strip plate moves to the position of the No. 1 bamboo strip plate, the second pressing roller 402 is still in the open state, and the preparation work for overlapping the No. 3 bamboo strip plate can continue.

[0060] When the positioning turntable fixture 3 is set to multiple, and the number of the feeding and cutting fixtures 4 corresponds to the number of the positioning turntable fixtures 3, and they are respectively set on the workbench 8 on one side of the positioning turntable fixture 3. For example, when there are two side-by-side fixtures as shown in the preferred embodiment, the two positioning turntable fixtures 3 are recorded as 3A and 3B, and the bottom of each positioning turntable fixture 3 is provided with a feeding and cutting fixture 4, which are recorded as 4A and 4B respectively. In actual application, it is preferred that the bamboo strips discs set on each positioning turntable fixture 3 are all made of the same bamboo strips material, for example, the positioning turntable fixture 3A is set as an axial bamboo strips disc, and the positioning turntable fixture 3B is set as an annular bamboo strips disc, and the switching between the bamboo strips discs 302 on each positioning turntable fixture 3 refers to the above process. At the same time, after the bamboo strips material in the positioning turntable tooling 3B passes through the feeding and cutting tooling 4B below it, it passes through the bottom of the feeding and cutting tooling 4A to avoid interference between the bamboo strips material on the positioning turntable tooling 3B and the bamboo strips material on the positioning turntable tooling 3A during feeding.

[0061] Furthermore, the switching process between the two positioning turntable toolings 3 is as follows: when the bamboo strips material in the positioning turntable tooling 3A is fed, the bamboo strips material is cut by the feeding and cutting tooling 4A, and the feeding and cutting tooling 4B starts to operate to transport the bamboo strips material forward, and the bamboo strips material can be overlapped with the bamboo strips material transported in the positioning turntable tooling 3A on the workbench 8 on one side of the feeding and cutting tooling 4A, and then the feeding of the bamboo strips material in the positioning turntable tooling 3B begins.

[0062] Further, the discharging tool 7 in the preferred embodiment is as follows Figure 8 As shown in , it includes a support frame fixedly arranged on the top surface of the end of the workbench 8 and a first motor 701 and a second motor 702 arranged on the support frame. The output shafts of the two motors are arranged in parallel, and a rotating shaft 703 is coaxially arranged corresponding to the output shaft of the first motor 701. The rotating shaft 703 is movably arranged on the support frame and can rotate under the drive of the first motor 701. At the same time, a pressing shaft 704 is correspondingly arranged above the rotating shaft 703, and the two ends of the pressing shaft 704 are respectively provided with support rods 706 matching the output shaft of the second motor 702. Through the drive of the second motor 702, the pressing shaft 704 can be moved closer to or away from the rotating shaft 703, and the distance between the pressing shaft 704 and the rotating shaft 703 can be changed. In actual work, the distance between the rotating shaft 703 and the pressing shaft 704 is less than the thickness of the bamboo strips material, so that the bamboo strips material can be clamped by the rotating shaft 703 and the pressing shaft 704 during feeding to prevent the material from slipping. Preferably, a guide shaft 705 is also provided on the support frame, which is a roller (i.e., a driven shaft) for guiding the feeding of the bamboo strips material. The material fed through the rotating shaft 703 is discharged from above or below the guide shaft 705.
