Abstract
Description
Technical Field
[0001] This utility model relates to the field of bamboo strip stamping technology, specifically to a bamboo strip stamping machine. Background Technology
[0002] Existing bamboo strip punching machines mostly employ semi-automatic or manually assisted feeding, which may lead to inaccurate positioning and bamboo strip flipping issues, affecting processing consistency and yield. Most of these machines have low levels of automation, relying heavily on human experience and monitoring. Demolding during the feeding process is difficult, and waste and finished products require manual sorting, resulting in low automation. Furthermore, many equipment processes have poor workflow coordination, limiting overall efficiency.
[0003] In traditional equipment, the feeding, stamping, and sorting processes are separate or driven by different power sources, resulting in mismatched cycle times and intermittent waiting times, leading to bottlenecks in overall production efficiency. In existing technologies, some of these three functions are semi-automated, while others are implemented by independent motors, transmission systems, and control systems. This results in complex equipment structures, large footprints, high manufacturing costs, numerous maintenance points, and high failure rates. Multiple independently driven systems require precise electrical or program control for coordination and synchronization. Signal delays or malfunctions in any link (such as sensor failure or inaccurate motor speed control) can lead to chaotic operations, such as delayed feeding causing blanking, inaccurate sorting causing stacking or jamming, or even machine collisions. The energy consumption of multiple motors operating simultaneously is inevitably higher than that of equipment with a single power source. Complex multi-system equipment requires operators with higher skills for debugging and maintenance, resulting in high maintenance costs. Utility Model Content

[0033] Example 1
[0034] Combined with appendix Figure 1-7 This embodiment proposes a bamboo strip punching machine, including a motor 1004, an eccentric wheel 1003, an eccentric journal 1013, a connecting rod 1014, a storage bin, a slider 1015, and a mold, all mounted on a frame 1001. The motor 1004 drives the eccentric wheel 1003 via a belt. The eccentric journal 1013 is connected to the eccentric wheel 1003. One end of the connecting rod 1014 is connected to the eccentric journal 1013, and the other end of the connecting rod 1014 is connected to one side of the slider 1015. The other side of the slider 1015 is connected to the upper mold 1 of the mold. The machine also includes a pusher rod and a pusher plate. 8010, sorting link 5, sorting component 61, waste channel 72 and receiving channel 62, one end of the push link is connected to the eccentric journal 1013, the other end of the push link is connected to the push plate 8010, the bottom of the storage tank is provided with a gap for the push plate 8010 to move, the storage tank is located on one side of the mold, the waste channel 72 is located on the other side of the mold, and the receiving channel 62 is located on the side of the waste channel 72 away from the mold; one end of the sorting link 5 is connected to the eccentric journal 1013, the other end of the sorting link 5 is connected to the sorting component 61, and the sorting component 61 is located above the receiving channel 62.
[0035] After motor 1004 starts, it drives eccentric wheel 1003 to rotate via belt. Eccentric journal 1013 rotates accordingly. Connecting rod 1014 moves up and down under the rotation of eccentric journal 1013, thereby driving slider 1015 to move up and down, which in turn drives upper die 1 to move up and down, realizing the die stamping process. At the same time, the pusher connecting rod moves with the rotation of eccentric wheel 1003, driving pusher plate 8010 to move. Pusher plate 8010 pushes bamboo pieces from the bottom gap of storage tank into the mold. That is, when the mold is open, that is, when connecting rod 1014 drives upper die to move up via slider 1015, bamboo pieces are pushed into the mold, realizing feeding and punching; when the mold is closed, that is, when upper die 1 moves down, pusher plate 8010 moves back to the outside of the bottom of mold and storage tank under the drive of pusher connecting rod, ready for the next feeding. It should be noted that in practical applications, the size of the gap, the thickness of the bamboo strip, and the thickness of the pusher plate 8010 should all be consistent, or the gap size should be slightly larger than the thickness of the pusher plate 8010, so that the pusher plate 8010 can move back and forth smoothly in the gap. However, the gap size should not be too large, to ensure that the pusher plate 8010 can push only one bamboo strip at a time, ensuring that the bamboo strip stamping quality is qualified, and avoiding the production of defective or substandard products.
[0036] Meanwhile, the sorting link 5 moves under the rotation of the eccentric wheel 1003, thereby driving the sorting component 61 to move. When the mold opens, the sorting link 5 drives the sorting component 61 to move into the mold to catch the stamped bamboo pieces falling from the upper mold 1. When the mold closes, the sorting link 5 drives the sorting component 61 to move outside the mold, and at the same time, the bamboo pieces slide from the sorting component 61 into the receiving channel 62, completing the sorting of the finished bamboo pieces. The sorting component 61 is located above the receiving channel 62, which facilitates the collection of the formed bamboo pieces after the sorting component 61 receives them and slides down into the receiving channel 62.
[0037] Motor 1004 drives eccentric wheel 1003 to rotate. Through the coordinated operation of various components in this embodiment, bamboo strip feeding, die stamping, and sorting of finished bamboo strips are completed simultaneously. This simplifies the power transmission structure of the stamping machine and maintains consistent cycle time for each process. Motor 1004 provides the power source, driving eccentric wheel 1003 to rotate. Eccentric wheel 1003, via eccentric journal 1013, drives connecting rod 1014 (for driving die stamping), pushing connecting rod (for driving feeding), and sorting connecting rod 5 (for driving sorting) to operate simultaneously, maintaining consistent cycle time. In other words, through the coordination of various functional components, one power source simultaneously completes the functions of multiple processes, improving bamboo strip processing efficiency.
[0038] The frame 1001 is used to support the various components of the bamboo strip punching machine, providing them with a stable support platform so that they can perform their respective functions. The motor 1004 provides the power source for the rotation of the eccentric wheel 1003. The rotation of the eccentric wheel 1003 provides power for feeding, punching and sorting through the eccentric journal 1013.
[0039] The connecting rod 1014 and the slider 1015 work together to realize the downward and upward motion trajectory during the stamping process. Driven by the eccentric journal 1013 of the eccentric wheel 1003, the upper die 1 of the mold is driven to move. The upper die 1 moves downward to perform stamping, and the upper die 1 moves upward to open the mold for sorting and feeding.
[0040] The push link and push plate 8010 work together to ensure that the movement trajectory of the feeding meets the ideal setting and will not affect the operation of other functional components. Driven by the eccentric journal 1013 of the eccentric wheel 1003, it keeps in sync with the action rhythm of the mold. When the mold opens, feeding is carried out. The push link drives the push plate 8010 to push the bamboo strip to be pressed to the bottom of the upper mold 1, that is, to the top of the lower mold 2. At the same time, the bamboo strip to be pressed pushes the bamboo waste material that was originally located on the lower mold 2 to the other side of the mold, that is, it is pushed into the waste channel 72 next to the other side of the mold, completing the collection of waste material and collecting it separately from the formed bamboo strip. When the mold is stamping, the push plate 1015 retracts to the side of the storage tank away from the mold, waiting for the next time the upper mold 1 moves up to feed.
[0041] The sorting linkage 5 and the sorting component 61 work together to ensure that the sorting trajectory meets the ideal setting and does not affect the operation of other functional components. Driven by the eccentric journal 1013 of the eccentric wheel 1003, the sorting component 61 moves in sync with the action rhythm of the mold. When the mold opens, the sorting linkage 5 moves the sorting component 61 into the mold, that is, between the upper mold 1 and the lower mold 2. The bamboo strips formed after stamping remain in the upper mold 1. The sorting component 61 is used to catch the formed bamboo strips falling from the lower mold 1. When the upper mold 1 moves downward, the formed bamboo strips slide from the sorting component 61 into the receiving channel 62, completing the collection of the formed bamboo strips and separating them from the bamboo waste. When the mold is stamping, the sorting component 61, driven by the sorting linkage 5, leaves the mold and moves to the outside of the mold, above the receiving channel 62. It waits for the upper mold 1 to move upward again to receive the material, so that the finished bamboo strips and the bamboo waste are separated, completing the sorting. Waste channel 72 and receiving channel 62 separate different types of bamboo strips after pressing, eliminating the need for manual sorting and achieving automated sorting.
[0042] As a further improvement to this embodiment, a conveyor belt 1002 is also included, mounted on the frame 1001. A partition plate 63 is fixedly provided along the length of the conveyor belt 1002, dividing the conveyor belt 1002 into a waste channel 72 and a receiving channel 62. The waste channel 72 is located on the other side of the mold. When waste bamboo pieces reach the waste channel 72 and shaped bamboo pieces reach the receiving channel 62, the conveyor belt 1002 transports them out respectively to prevent accumulation from affecting the next forming and the feeding of waste bamboo pieces. In practical applications, the partition plate 63 can be fixed on the frame 1001 or on the conveyor belt 1002; the conveyor belt 1002 is driven by a motor and is not shown in the attached drawings.
[0043] As a further improvement to this embodiment, the push link includes push link one 8001, push link two 8002, push link three 8003, push link four 8004, push link five 8005, push link six 8006, push link seven 8007, push link eight 8008, and push seat 8009. One end of push link one 8001 is connected to the eccentric journal 1013, and the other end of push link one 8001 is connected to one end of push link two 8002. The other end of the second 8002, the third push link 8003, the fourth push link 8004 and the fifth push link 8005 are connected in sequence. The other end of the fifth push link 8005 is sleeved on the sixth push link 8006. One end of the seventh push link 8007 is sleeved on the sixth push link 8006. The other end of the seventh push link 8007 is connected to one end of the eighth push link 8008. The other end of the eighth push link 8008 is connected to the push seat 8009. The push seat 8009 is provided with a push plate 8010.
[0044] When the eccentric wheel 1003 rotates, one end of the push link 8001 connected to the eccentric journal 1013 moves up and down, thereby driving the push links 8002, 8003, 8004, and 8005 to move. The push link 8005 drives the push link 8006 to rotate, and the push links 8007 and 8008 to move, which in turn drives the push seat 8009 and the push plate 8010 to move, pushing the bamboo strips 8013 at the bottom gap of the storage silo to move. The rotation of the eccentric wheel 1003 is converted into the movement of the push plate 8010 by the push link 5, realizing automatic feeding with the rotation rhythm, and pushing the waste bamboo strips into the waste channel 72.
[0045] In a specific application, as another improvement, a storage platform 8014 is also provided on the frame 1001. The storage tank and the pusher plate 8010 are both located on the surface of the storage platform 8014, and the pusher seat 8009 is located below the storage platform 8014.
[0046] The rotation of the eccentric wheel 1003, via the push link, drives the feeding plate 8010 to move, thereby pushing the bamboo strips 8013, thus realizing the feeding process. The eccentric wheel 1003 drives the push link 8008 via the eccentric journal 1013, which in turn pushes the push plate 8010 to move. As the upper mold moves upward and the mold opens, the push plate 8010 moves forward, pushing the bamboo strips 8013 at the bottom of the storage bin into the mold. At the same time, the bamboo strips push the waste material that remains on the lower mold 2 after pressing into the waste channel 72. As the upper mold 1 moves downward and the mold closes, the push plate 8010, driven by the push link, retracts to the outside of the mold and storage bin. The bamboo strips 8013 in the storage bin fall into the gap at the bottom of the storage bin, located on the surface of the storage platform 8014, ready for the push plate 8010 to push them into the mold the next time the upper mold 1 moves upward.
[0047] The storage silo includes a first storage plate 8011 and a second storage plate 8012. The second storage plate 8012 is located on one side of the mold and fixed to the storage platform 8014. The first storage plate 8011 is fixed on the second storage plate 8012. On the side of the storage silo parallel to the second storage plate 8012, several interconnected first storage plates 8011 are arranged. The first storage plates 8011 and the second storage plate 8012 are interconnected to form the storage silo. Bamboo strips 8013 are stacked together in the storage silo. When the pusher plate 8010 pushes the bamboo strips 8013 located in the gaps into the mold, the pusher plate 8010 retracts and returns to its original position. At this time, the bamboo strips 8013 in the storage silo fall under the action of gravity, and the bamboo strips 8013 fill the gaps for the next push.
[0048] The height of the gap is greater than or equal to the thickness of a single bamboo strip 8013, but less than twice the thickness of a single bamboo strip 8013. The thickness of the pusher plate 8010 is less than or equal to the thickness of a single bamboo strip 8013. The pusher plate 8010 pushes only one bamboo strip 8013 into the mold at a time, ensuring that each bamboo strip 8013 is successfully stamped. The height of the gap and the thickness of the pusher plate 8010 ensure that the pusher plate 8010 can only push one bamboo strip 8013 at a time, thereby ensuring that the bamboo strip is pressed to the required standard.
[0049] Example 2
[0050] Combined with appendix Figure 5-7Compared with any technical solution in Embodiment 1, the bamboo strip punching machine of this embodiment can be improved as follows: The mold includes stripping pillars 3, upper mold 1 and lower mold 2. The upper mold 1 is provided with an upper mold cavity 131 and an upper mold core 14, and the upper mold core 14 is located in the upper mold cavity 131. The lower mold 2 is provided with a lower mold cavity 211 and a lower mold core 222, and the lower mold core 222 is located in the lower mold cavity 211. The upper mold cavity 131 and the lower mold cavity 211 are correspondingly matched, and the upper mold core 14 and the lower mold core 222 are correspondingly matched. The upper mold 1 is provided with a plurality of stripping pillars 3. One end of the stripping pillar 3 is located outside the upper mold 1, and the other end of the stripping pillar 3 is located on the top surface of the upper mold core 14 inside the upper mold 1. The frame 1001 is provided with a plurality of limiting pillars 31, and the limiting pillars 31 are opposite to the stripping pillars 3.
[0051] Motor 1004 drives eccentric wheel 1003 to rotate. When upper mold 1 moves upward, push linkage moves, push plate 8010 pushes bamboo strip 8013 into the space between upper mold 1 and lower mold 2. At the same time, the pushed bamboo strip 8013 pushes the bamboo waste material originally located between upper mold 1 and lower mold 2 into the waste material channel 72 on the other side of the mold. The bamboo strip 8013 to be stamped is located on the lower mold cavity 211. Limit post 31 touches stripping post 3 and pushes stripping post 3 to move downward relative to upper mold 1. Stripping post 3 pushes the top surface of upper mold core 14. Upper mold core 14 moves downward and pushes the formed bamboo strip out from upper cavity 131. Push linkage 5 drives sorting part 61 to extend into the mold, that is, between upper mold 1 and lower mold 2, to catch the fallen formed bamboo strip. The formed bamboo strip slides down along sorting part 61 into receiving channel 62.
[0052] When the upper mold 1 moves down, it presses, and the upper mold core 14 and the lower mold core 222 act on both sides of the bamboo strip 8013 to cut it. The cut bamboo strip remains in the upper mold cavity 131. The push linkage 5 drives the push plate 8010 to retract to the outside of the storage silo. The bamboo strip in the storage silo moves down under the action of gravity and falls into the gap between the bottom of the storage silo and the storage platform 8014. The receiving linkage 5 drives the sorting part 61 to move to the outside of the mold.
[0053] The receiving surface of the receiving component 61 forms an angle with the sorting link 5, and the receiving surface of the receiving component 61 is inclined, so that when the mold is opened, the receiving surface of the receiving component 61 is located between the upper mold 1 and the lower mold 2 of the mold, and is used to catch the shaped bamboo strips falling from the upper mold 1. The edge of the receiving surface faces the receiving channel 62, so that the shaped bamboo strips can slide along the receiving surface into the receiving channel 62, thereby separating the shaped bamboo strips. The eccentric wheel 1003 rotates, and the stamping link drives the upper mold 1 of the mold to move. When the mold is closed, the sorting link 5 moves the receiving component 61 to the outside of one side of the mold, making way for the mold stamping, and will not affect the stamping of the bamboo strips.
[0054] As a further improvement, the mold also includes a mold pin 15, which is located inside the upper mold core 14. One end of the mold pin 15 is located on the bottom surface of the upper mold core 14, and the other end of the mold pin 15 is located on the top surface of the upper mold core 14. The lower mold core 222 is provided with a hole that matches the mold pin 15.
[0055] During stamping, the bamboo strip is located between the upper die 1 and the lower die 2. The upper die 1 and the lower die 2 are close to each other and press against each other. The upper die core 14 and the lower die core 222 press against each other. The die needle 15 passes through the bamboo strip and extends into the hole on the lower die core 222 to punch a hole in the bamboo strip.
[0056] As a further improvement, the upper mold 1 includes a mold base plate 11, a mold base plate 2 12, and a mold base plate 3 13, which are stacked sequentially, and the upper mold cavity 131 is disposed on the mold base plate 3 13; the lower mold 2 includes a mold base plate 4 21 and a mold base plate 5 22, which are connected, the lower mold cavity 211 is disposed on the mold base plate 4 21, and the lower mold core 222 is disposed on the mold base plate 5 22.
[0057] The split structure of the upper mold 1 facilitates the machining of the upper mold cavity 131, as well as the machining and assembly of the various structures within the upper mold 1. Similarly, the split structure of the lower mold 2 facilitates the machining of the lower mold 2, as well as the machining and assembly of the various structures within the lower mold 2. Furthermore, it allows for easy replacement of the upper mold cavity 131, upper mold core 14, lower mold cavity 211, and lower mold core 222 when different shapes of bamboo strips need to be pressed.
[0058] The mold base plate 4 21 and mold base plate 5 22 are connected by several springs 221, which are located between the mold base plate 4 21 and mold base plate 5 22. One end of the spring 221 is connected to the mold base plate 4 21, and the other end of the spring 221 is connected to the mold base plate 5 22, that is, the spring 221 is located between the mold base plate 4 21 and mold base plate 5 22. When the upper mold 1 and the lower mold 2 press against each other, the mold base plate 3 13 where the upper mold cavity 131 is located and the mold base plate 4 21 where the lower mold cavity 211 is located come into contact and press against each other, the spring 221 is compressed, the lower mold core 222 on the mold base plate 5 22 extends out of the lower mold cavity 211 and cooperates with the upper mold core 14, distributed on both sides of the bamboo strip, to press the bamboo strip and cut it into shape; after cutting, the upper mold 1 and the lower mold 2 separate, and the spring 221 returns to its original position. In practical applications, the springs 221 are distributed on the opposing surfaces of the mold base plate 4 21 and the mold base plate 5 22. In order not to affect the setting of the lower mold core 222, two springs 221 are distributed at each end of the lower mold core 222.
[0059] The top surface of the upper mold core 14 is larger than the bottom surface. The upper mold core 14 matches the contour of the upper mold cavity 131. When the upper mold core 14 is pushed by the stripper column 3 and moves in the upper mold cavity 131, this structural design of the upper mold core 14 prevents it from falling out of the upper mold cavity 131, thereby ensuring the normal operation of the entire mold.
[0060] As a further improvement, both the mold base plate 11 and the mold base plate 2 are provided with stripper column channels 111. One end of the stripper column 3 is located outside the mold base plate 11, and the other end of the stripper column 3 is located inside the stripper column channels 111 in the mold base plate 11 and the mold base plate 2.
[0061] After the stripper column 3 touches the limiting column 31, it moves in the stripper column channel 111, pushing the upper mold core 14 to move in the upper mold cavity 131, pushing the formed bamboo strip that is attached to the bottom surface of the upper mold core 14 out of the upper mold cavity 131. The stripper column channel 111 provides movement space for the stripper column 3 within the upper mold 1. The number and position of the stripper column channels 111 correspond one-to-one with the number and position of the stripper column 3, so that all the stripper columns 3 can act on the upper mold core 14, allowing all parts of the formed bamboo strip to be stressed simultaneously, facilitating the smooth pushing out of the formed bamboo strip. The limiting column 31 is fixed to the frame 1001 and corresponds to the number and position of the stripper column 3. In specific applications, it can be a bolt or a stainless steel column, etc., to provide assistance for the movement of the upper mold core 14 in the upper mold cavity 131.
[0062] As a further improvement, the mold base plate 3 13 is provided with a guide hole 133, which matches the guide post 213. The guide post 213 is provided on the mold base plate 4 21 of the lower mold 2. The mold base plate 4 21 is provided with a limiting protrusion 212, which is located at both ends of the lower mold cavity 211. The mold base plate 3 13 of the upper mold 1 is provided with a limiting groove 132, which is located at both ends of the upper mold cavity 131 on the mold base plate 3 13. The limiting protrusion 212 cooperates with the limiting groove 132.
[0063] Guide posts 213 extend into guide holes 133, and the two match each other. When the upper mold 1 and the lower mold 2 press against each other, they play a guiding role, which helps to achieve the pressing and shaping of bamboo strips. In specific implementation, based on this, it is conceivable to set multiple pairs of guide posts 213 and guide holes 133 to jointly play a guiding role, so that the upper mold core 14 and the lower mold core 222 are aligned, and the upper mold cavity 131 and the lower mold cavity 211 are aligned, which facilitates the smooth pressing and shaping of bamboo strips.
[0064] The limiting protrusions 212 and the limiting grooves 132 cooperate correspondingly. Before the upper mold 1 and the lower mold 2 press against each other, the bamboo strip to be processed is placed on the surface of the lower mold cavity 211. The bamboo strip is located between the limiting protrusions 212 at both ends of the lower mold cavity 211. The two limiting protrusions 212 limit the bamboo strip, ensuring that the bamboo strip is placed longitudinally along the lower mold 2 and preventing misalignment. When the upper mold 1 and the lower mold 2 press against each other, the limiting protrusions 212 cooperate with the limiting grooves 132. The limiting protrusions 212 enter the limiting grooves 132, ensuring that both the upper mold core 14 and the lower mold core 222 apply pressure to the bamboo strip. The limiting protrusions 212 and the limiting grooves 132 can limit the bamboo strip, ensuring that the bamboo strip does not misalign longitudinally along the lower mold 2 due to pressure.
[0065] As a further improvement, a waste collection bin and a receiving bin are also included. Along the running direction of the conveyor belt 1002, a waste collection bin is provided at the tail end 721 of the waste channel 72, and a receiving bin is provided at the tail end 621 of the receiving channel 62. Transported by the conveyor belt 1002, the waste in the waste channel 72 is conveyed to the waste collection bin, and the shaped bamboo strips in the receiving channel 62 are conveyed to the receiving bin, achieving separate placement of the two and eliminating the need for manual sorting.
[0066] The bamboo strip is located between the upper mold 1 and the lower mold 2. The upper mold 1 and the lower mold 2 press against each other, and the upper mold core 14 and the lower mold core 222 cooperate with each other, as shown below. Figure 5 As shown, pressure is applied to the bamboo strips to press them into shape. The shaped bamboo strips remain in the upper mold cavity 131. After the upper mold 1 and the lower mold 2 separate, one end of the ejector pin 3 located outside the upper mold 1 touches the limiting pin 31. The ejector pin 31 moves in the upper mold 1, and one end of the ejector pin 3 pushes the top surface of the upper mold core 14 and moves in the upper mold cavity 131. The upper mold core 14 pushes the shaped bamboo strips out of the upper mold cavity 131, thus achieving demolding.
[0067] The stamping die is mounted on the stamping press, and the aforementioned limiting post 31 is mounted on the stamping press. In a specific embodiment, the limiting post 31 can be a rigid object that contacts the stripper post 3, capable of withstanding the pressure of the stripper post 3 without deformation, and relying on the reverse force of the limiting post 31 to push the stripper post 3 to move in the upper die cavity 131, with no restriction on shape.
[0068] As shown in the figure, a limiting post 31—a bolt—is set on the stamping machine, corresponding to the position of the stripper post 3. After the bamboo strip is pressed into shape, it remains in the upper mold cavity 131. When the upper mold 1 and the lower mold 2 separate, the stripper post 3 moves together with the upper mold 1 until one end of the stripper post 3 touches the bolt. Relative to the upper mold 1, the stripper post 3 moves within the upper mold 1, and the other end of the stripper post 3 pushes the top surface of the upper mold core 14 to move within the upper mold cavity 131. The upper mold core 14 then pushes the formed bamboo strip out of the upper mold cavity 131. Based on this, it is easy to see that the distance the stripper column 3 moves within the upper mold 1 is the same as the distance the upper mold core 14 moves within the upper mold cavity 131. Since this movement process can push the formed bamboo strip out of the upper mold cavity 131, this distance should be greater than or equal to the thickness of the bamboo strip to ensure that the formed bamboo strip can be smoothly removed from the upper mold cavity 131. Therefore, the distance the upper mold core 14 can move within the upper mold cavity 131 should be greater than the distance the stripper column 3 moves within the upper mold 1 to avoid damage to the stripper column 3, the upper mold core 14, and the upper mold cavity 131. This makes the mold design logic reasonable and consistent with actual application conditions.
[0069] In practical use, the bamboo strip is placed on the side of the lower mold 2 that mates with the upper mold 1, i.e., on the lower mold cavity 211. The upper mold 1 and lower mold 2 approach each other and press against each other. The upper mold core 14, located in the upper mold cavity 131, moves towards the bamboo strip through the upper mold cavity 131, and the lower mold core 222, located in the lower mold cavity 211, also moves towards the bamboo strip through the lower mold cavity 211. Both the upper mold core 14 and the lower mold core 222 apply pressure to the bamboo strip, pressing it into shape. The upper mold 1 and lower mold 2 then separate and move away from each other. The pressed bamboo strip is located on the lower mold 2, and the shaped bamboo strip is located in the upper mold cavity 131 and cannot fall off by itself. After the upper mold 1 and lower mold 2 separate, one end of the stripper column 3 outside the upper mold 1 touches the limiting column 31. The limiting column 31 pushes the stripper column 3 to move within the upper mold 1, and the other end of the stripper column 3 pushes the upper mold core 14 to move within the upper mold cavity 131. The upper mold core 14 pushes the formed bamboo strips out of the upper mold cavity 131. The sorting component 61 catches the formed bamboo strips and conveys them to the receiving channel 62, completing the sorting process.
[0070] The shaped bamboo strips, such as fan ribs or umbrella ribs, are generally long and narrow. Correspondingly, both the upper mold 1 and the lower mold 2 have a certain length. Therefore, to ensure successful stripping, multiple stripping pillars 3 can be set, along with multiple corresponding limiting pillars 31. The positions of the multiple limiting pillars 31 correspond to the positions of the multiple stripping pillars 3. After the upper mold 1 and the lower mold 2 separate, each limiting pillar 31 can push one stripping pillar 3 to move. The stripping pillar 3 is cylindrical in shape, and its cross-sectional shape can be circular, square, triangular, etc., to facilitate pushing. The multiple stripping pillars 3 are evenly distributed at one end within the upper mold 1. When acted upon by the limiting pillars 31, they can simultaneously apply pressure to the upper mold core 14, thereby smoothly pushing the shaped bamboo strip out of the upper mold cavity 131.
[0071] The shapes of the sides of the upper mold core 14 and the lower mold core 222 that contact the bamboo strip, as well as the corresponding shapes of the upper mold cavity 131 and the lower mold cavity 211, are the same as the shapes of the formed bamboo strips, so as to press the bamboo strips into shape.
[0072] When stamping bamboo strips, the lower die core 222 extends out of the lower die cavity 211 and, together with the upper die core 14, acts on both sides of the bamboo strip. That is, the lower die core 222 acts on one side of the bamboo strip, and the upper die core 14 acts on the other side of the bamboo strip. During stamping, the upper die core 14 and the lower die core 222 are used to cut the bamboo strip and press it into shape.
[0073] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
