Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a continuous bevel sawing device and method. Background Technology

[0002] Cutting square steel pipes is a common operation in metal processing. Sawing methods typically include manual sawing, mechanical sawing, and band sawing. Manual sawing is the most basic method, using a hand saw, but this method is labor-intensive and is generally used for small batches of simple cutting operations with low precision requirements. Band sawing, using a band saw machine, is a highly efficient sawing device that uses a circular saw band for cutting. The saw band can operate continuously, but it occupies a large space and is inconvenient to maintain. Circular sawing uses a high-speed rotating circular saw blade for cutting. The material and tooth design of the saw blade vary depending on the object being cut. Circular saws have a smaller overall size and are easy to maintain. However, due to the high-speed rotation of the saw blade, it is necessary to prevent severe vibration of the steel pipe and the saw blade during circular sawing.

[0003] Chinese patent CN221582159U discloses a square steel pipe cutting device, including a base, a fixed frame, a cutting device, a drive assembly, a pad, and a collection box. The fixed frame is located above the base, and the cutting device is located above the fixed frame. The drive assembly includes a transmission component, a motor, a bidirectional screw, and two sets of clamping components. The transmission component is located outside the fixed frame. The output end of the motor is fixedly connected to one end of the bidirectional screw and is located outside the fixed frame. The other end of the bidirectional screw is rotatably connected to the fixed frame and is located inside the fixed frame. The surface of the bidirectional screw has bidirectional threads. The clamping components are threadedly connected to the bidirectional screw and are located inside the fixed frame. The pad is located inside the fixed frame. The collection box is detachably connected to the base and is located outside the base. The bidirectional screw can effectively clamp the square steel pipe. By rotating the bidirectional screw, the square steel pipe is clamped. The cutting device moves downward to cut the square steel pipe.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patented technology can effectively clamp square steel pipes using a bidirectional screw and cut them by a downward-moving cutting device. However, it cannot continuously feed square steel pipes or quickly separate waste and finished products after cutting, resulting in low production efficiency.

[0006] Based on this, the present invention designs a continuous bevel sawing device and method to solve the above problems. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a continuous bevel sawing device and method.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A continuous bevel sawing device includes a frame. A first limiting strip is fixedly installed on the left side of the frame. A continuous cutting device for cutting L-shaped square tubes is arranged behind the first limiting strip. A second limiting strip is arranged in front of the first limiting strip and is fixedly installed on the left side of the frame. A first cylinder is arranged on the left side of the second limiting strip and is fixedly installed on the left side of the frame by fixing screws. A pressure plate for pressing down the L-shaped square tubes is fixedly installed at the output end of the first cylinder. A feeding device for continuously feeding the cut L-shaped square tubes is arranged on the right side of the continuous cutting device. A rotary feeding device for continuously feeding the L-shaped square tubes is arranged on the right side of the feeding device.

[0010] The continuous cutting device includes: a support bracket, a rotating bracket, a drive motor, a gearbox, a saw blade, and a second cylinder. The support bracket is fixedly installed on the left side of the frame. The rotating bracket is rotatably connected to the support bracket via a rotating shaft. The drive motor is fixedly installed on the upper side of the rotating bracket. The gearbox is fixedly installed on the front side of the motor housing of the drive motor. The input shaft of the gearbox is fixedly connected to the output shaft of the drive motor. The saw blade is fixedly installed on the output shaft of the gearbox. The lower side of the second cylinder is rotatably connected to the rear side of the frame via a rotating shaft. The output shaft of the second cylinder is rotatably connected to the rear side of the rotating bracket via a rotating shaft.

[0011] Furthermore, the left side of the support bracket is provided with multiple first protrusions, and the side wall of the rotating bracket is provided with multiple second protrusions, which are used to limit the maximum angle of leftward rotation of the rotating bracket on the support bracket.

[0012] Furthermore, the rotary feeding device includes a continuous pushing assembly and a rotary feeding assembly. The continuous pushing assembly is installed on the right side of the frame, and the rotary feeding assembly is installed on the upper side of the continuous pushing assembly. The continuous pushing assembly includes a third limiting bar, a pushing plate, a third cylinder, and an auxiliary sliding assembly. The two third limiting bars are symmetrically fixedly installed on the frame along the central axis of the frame. The pushing plate is disposed between the two third limiting bars and can slide left and right between the two third limiting bars. The third cylinder is fixedly installed on the right side of the frame, and the right side of the pushing plate is fixedly connected to the output end of the third cylinder. The auxiliary sliding assembly is installed on the left side of the pushing plate. The auxiliary sliding assembly includes auxiliary rollers, and multiple auxiliary rollers are rotatably connected to the left side wall of the pushing plate through a rotating shaft.

[0013] Furthermore, the rotary feeding assembly includes: a fixed disc, an indexing disc, a rotating disc, vertical supports, and L-shaped square tubes. The fixed disc is fixedly installed on the upper side of the third limiting bar. The indexing disc is fixedly installed on the frame. The rotating disc is fixedly installed on the upper side of the indexing disc. Four L-shaped openings are arranged in a circular array along the center circumference of the rotating disc. The L-shaped openings are used to place L-shaped square tubes. Multiple vertical supports are arranged around each L-shaped opening to form an L-shaped space for stacking L-shaped square tubes. The vertical supports are fixedly installed on the upper side of the rotating disc, and the L-shaped square tubes are vertically stacked on the L-shaped openings.

[0014] Furthermore, an L-shaped opening is provided on the left side of the fixed disc to accommodate an L-shaped square tube. The thickness of the fixed disc is the same as the thickness of the L-shaped square tube. A rectangular slot is provided on the right side of the pusher plate to avoid the output shaft of the indexing plate.

[0015] Furthermore, the height of the third limiting bar is slightly higher than that of the L-shaped square tube, allowing the L-shaped square tube to slide between the frame and the fixed disc.

[0016] Furthermore, a linear module is installed on the lower side of the frame, and multiple fixing posts are fixedly installed on the output end of the linear module. A strip-shaped opening is provided on the middle side of the frame, and the fixing posts slide through the strip-shaped opening and are slidably connected to the strip-shaped opening.

[0017] Furthermore, the feeding device includes: a fourth cylinder, a horizontal plate, and a finished product feeding trough. The fourth cylinder is fixedly installed on the rear side of the frame, the horizontal plate is fixedly installed on the output end of the fourth cylinder, and the finished product feeding trough is fixedly installed on the front side of the frame.

[0018] Furthermore, an irregularly shaped opening is provided on the left side of the first limiting strip, and a waste material discharge chute is fixedly installed on the lower side of the irregularly shaped opening.

[0019] To better achieve the objectives of this invention, the present invention also provides a method for continuous bevel sawing equipment, comprising the following steps:

[0020] Step 1: Using manual labor or a robotic arm, multiple L-shaped square tubes are placed into the L-shaped openings of the rotating disk of the rotating feeding assembly. The indexing plate drives the rotating disk to rotate 90 degrees periodically. The L-shaped openings on the left side of the rotating disk and the left side of the fixed disk coincide, causing the L-shaped square tubes to fall into the L-shaped openings on the left side of the fixed disk. Then, the output shaft of the third cylinder of the continuous pushing assembly shortens, causing the pushing plate to move to the right. The pushing plate moves to the right, causing the L-shaped square tubes in the L-shaped openings on the left side of the fixed disk to fall down. The output shaft of the third cylinder extends, causing the pushing plate to move to the left, pushing the L-shaped square tubes towards the second limiting bar. At this time, the output shaft of the third cylinder is still in the extended state. The output end of the first cylinder extends, causing the pressure plate to move towards the position of the L-shaped square tubes, pressing the L-shaped square tubes at the position of the first limiting bar. The L-shaped square tubes are fixed at the positions of the first and second limiting bars.

[0021] Step 2: The output shaft of the drive motor of the continuous cutting device rotates, driving the gearbox, which in turn drives the saw blade. The output shaft of the second cylinder extends, causing the rotating bracket to rotate to the left. The rotation of the rotating bracket to the left drives the drive motor, gearbox, and saw blade to rotate to the left. The saw blade cuts the L-shaped square tube fixed on the first and second limiting bars. After the L-shaped square tube is cut by the saw blade, the waste falls into the waste discharge trough. After the cutting is completed, the output shaft of the second cylinder shortens, causing the rotating bracket to rotate to the right. The rotation of the rotating bracket to the right drives the drive motor, gearbox, and saw blade to rotate to the right. The saw blade is lifted, waiting for the next cut. At this time, the output shaft of the third cylinder shortens, waiting for the next feeding.

[0022] Step 3: The output end of the linear module moves to the right, causing the fixed column to move to the right. The fixed column moves to the right, causing the L-shaped square tube to move to the right. After the L-shaped square tube moves a certain distance, the output end of the linear module returns to its initial state. The output end of the fourth cylinder of the feeding device extends, causing the horizontal plate to move forward. The horizontal plate moves forward, pushing the L-shaped square tube forward and pushing it into the finished product feeding slot. The output end of the fourth cylinder returns to its initial position, waiting for the next feeding.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses the extension of the output end of the first cylinder to drive the pressure plate to move towards the position of the L-shaped square tube, pressing the L-shaped square tube at the position of the first limiting strip. The extension of the output shaft of the third cylinder drives the pusher plate to move to the left, pushing the L-shaped square tube towards the second limiting strip. At this time, the output shaft of the third cylinder is still in the extended state, which is conducive to fixing the L-shaped square tube quickly from multiple directions. The output shaft of the drive motor of the continuous cutting device rotates to drive the gearbox, which in turn drives the saw blade to rotate. The extension of the output shaft of the second cylinder drives the rotating bracket to rotate to the left. The rotation of the rotating bracket to the left drives the drive motor, gearbox and saw blade to rotate to the left. The saw blade cuts the L-shaped square tube fixed on the first and second limiting strips. After the cutting is completed, the saw blade is lifted up to wait for the next cutting, which is conducive to continuous cutting of the L-shaped square tube.

[0024] 2. After the L-shaped square tube is cut by the saw blade, the waste falls into the waste discharge trough, which facilitates the rapid discharge of waste. After the cutting is completed, the saw blade is lifted to wait for the next cut. The output end of the linear module moves to the right, which drives the fixed column to move to the right. The fixed column moves to the right, which drives the L-shaped square tube to move to the right. After the L-shaped square tube moves to a certain distance, the output end of the linear module returns to the initial state. The output end of the fourth cylinder of the feeding device extends, which drives the horizontal plate to move forward. The horizontal plate moves forward and pushes the L-shaped square tube forward, pushing the L-shaped square tube into the finished product discharge trough. The output end of the fourth cylinder returns to the initial position to wait for the next feeding, which facilitates the rapid discharge of the finished L-shaped square tube.

[0025] 3. The indexing plate drives the rotating disk to rotate 90 degrees periodically. The L-shaped opening on the left side of the rotating disk coincides with the L-shaped opening on the left side of the fixed disk, causing the L-shaped square tube to fall into the L-shaped opening on the left side of the fixed disk. Then, the output shaft of the third cylinder of the continuous feeding component shortens, causing the feeding plate to move to the right. The movement of the feeding plate to the right causes the L-shaped square tube in the L-shaped opening on the left side of the fixed disk to fall down. The output shaft of the third cylinder extends, causing the feeding plate to move to the left, pushing the L-shaped square tube towards the second limiting bar, which is conducive to the continuous feeding of L-shaped square tubes.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] The present invention will be further described below with reference to embodiments.

[0040] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0041] Example 1: In some examples, please refer to Figures 1-9A continuous bevel sawing device includes a frame 1. A first limiting strip 2 is fixedly installed on the left side of the frame 1. A continuous cutting device 3 for cutting L-shaped square tubes 89 is provided behind the first limiting strip 2. A second limiting strip 4 is provided in front of the first limiting strip 2 and is fixedly installed on the left side of the frame 1. A first cylinder 5 is provided on the left side of the second limiting strip 4 and is fixedly installed on the left side of the frame 1 by fixing screws. A pressure plate 6 for pressing down the L-shaped square tubes 89 is fixedly installed at the output end of the first cylinder 5. A feeding device 7 for continuously feeding the cut L-shaped square tubes 89 is provided on the right side of the continuous cutting device 3. A rotary feeding device 8 for continuously feeding the L-shaped square tubes 89 is provided on the right side of the feeding device 7.

[0042] The first limiting strip 2 restricts the upper position of the L-shaped square tube 89, and the second limiting strip 4 restricts the left position of the L-shaped square tube 89, thus determining the position of the L-shaped square tube 89 in the plane. The output end of the first cylinder 5 extends and drives the pressure plate 6 to move towards the position of the L-shaped square tube 89, pressing the L-shaped square tube 89 at the position of the first limiting strip 2. The L-shaped square tube 89 is fixed to the second limiting strip 4 by the rotating feeding device 8. One end of the L-shaped square tube 89 is cut by the continuous cutting device 3, and the cut L-shaped square tube 89 is continuously fed by the unloading device 7.

[0043] The continuous cutting device 3 includes: a support bracket 31, a rotating bracket 32, a drive motor 33, a gearbox 34, a saw blade 35, and a second cylinder 36. The support bracket 31 is fixedly installed on the left side of the frame 1. The rotating bracket 32 ​​is rotatably connected to the support bracket 31 via a rotating shaft. The drive motor 33 is fixedly installed on the upper side of the rotating bracket 32. The gearbox 34 is fixedly installed on the front side of the motor housing of the drive motor 33. The input shaft of the gearbox 34 is fixedly connected to the output shaft of the drive motor 33. The saw blade 35 is fixedly installed on the output shaft of the gearbox 34. The lower side of the second cylinder 36 is rotatably connected to the rear side of the frame 1 via a rotating shaft. The output shaft of the second cylinder 36 is rotatably connected to the rear side of the rotating bracket 32 ​​via a rotating shaft.

[0044] The output shaft of the drive motor 33 of the continuous cutting device 3 rotates, driving the gearbox 34, which in turn drives the saw blade 35 to rotate. The output shaft of the second cylinder 36 extends, causing the rotating bracket 32 ​​to rotate to the left. The rotation of the rotating bracket 32 ​​to the left causes the drive motor 33, gearbox 34, and saw blade 35 to rotate to the left. The saw blade 35 cuts the L-shaped square tube 89 fixed on the first limiting bar 2 and the second limiting bar 4. After the cutting is completed, the output shaft of the second cylinder 36 shortens, causing the rotating bracket 32 ​​to rotate to the right. The rotation of the rotating bracket 32 ​​to the right causes the drive motor 33, gearbox 34, and saw blade 35 to rotate to the right. The saw blade 35 is lifted up, waiting for the next cut, which is beneficial for continuous cutting of the L-shaped square tube 89.

[0045] The support bracket 31 has multiple first protrusions 9 on its left side, and the rotating bracket 32 ​​has multiple second protrusions 10 on its side wall, which are used to limit the maximum angle of rotation of the rotating bracket 32 ​​to the left on the support bracket 31.

[0046] Example 2: In some embodiments, such as Figures 1-9 As shown, in a preferred embodiment of the present invention, the rotary feeding device 8 includes a continuous pushing component and a rotary feeding component. The continuous pushing component is installed on the right side of the frame 1, and the rotary feeding component is installed on the upper side of the continuous pushing component.

[0047] The continuous pushing component continuously pushes the L-shaped square tube 89 to the left, while the rotary feeding component rotates and feeds the L-shaped square tube 89, ensuring that the L-shaped square tube 89 can be continuously fed.

[0048] The continuous feeding assembly includes: a third limiting bar 81, a feeding plate 82, a third cylinder 83, and an auxiliary sliding assembly. The two third limiting bars 81 are symmetrically fixedly installed on the frame 1 along the central axis of the frame 1. The feeding plate 82 is disposed between the two third limiting bars 81 and can slide left and right between the two third limiting bars 81. The third cylinder 83 is fixedly installed on the right side of the frame 1. The right side of the feeding plate 82 is fixedly connected to the output end of the third cylinder 83. The auxiliary sliding assembly is installed on the left side of the feeding plate 82.

[0049] The auxiliary sliding assembly includes: auxiliary rollers 84, and a plurality of auxiliary rollers 84 are rotatably connected to the left side wall of the pusher plate 82 via a rotating shaft.

[0050] The output shaft of the third cylinder 83 of the continuous pushing assembly extends, causing the pushing plate 82 to move to the left. The leftward movement of the pushing plate 82 causes the auxiliary roller 84 to move to the left. The leftward movement of the auxiliary roller 84 pushes the L-shaped square tube 89 toward the second limiting strip 4, so that the left side of the L-shaped square tube 89 is tightly attached to the second limiting strip 4. Then, the output end of the first cylinder 5 extends, causing the pressure plate 6 to move toward the position of the L-shaped square tube 89, pressing the L-shaped square tube 89 onto the position of the first limiting strip 2. The auxiliary roller 84 is used to reduce the friction when the L-shaped square tube 89 moves toward the first limiting strip 2, which is beneficial for quickly fixing the L-shaped square tube 89 from multiple directions.

[0051] The rotary feeding assembly includes: a fixed disc 85, an indexing disc 86, a rotating disc 87, vertical supports 88, and L-shaped square tubes 89. The fixed disc 85 is fixedly installed on the upper side of the third limiting bar 81. The indexing disc 86 is fixedly installed on the frame 1. The rotating disc 87 is fixedly installed on the upper side of the indexing disc 86. Four L-shaped openings 810 are arranged along the circumference of the center of the rotating disc 87. The L-shaped openings 810 are used to place the L-shaped square tubes 89. Multiple vertical supports 88 are arranged around each L-shaped opening 810 to form an L-shaped space for stacking the L-shaped square tubes 89. The vertical supports 88 are fixedly installed on the upper side of the rotating disc 87. The L-shaped square tubes 89 are vertically stacked on the L-shaped openings 810.

[0052] The fixed disc 85 has an L-shaped opening 810 on its left side to accommodate an L-shaped square tube 89. The thickness of the fixed disc 85 is the same as the thickness of the L-shaped square tube 89. The pusher plate 82 has a rectangular slot 11 on its right side to avoid the output shaft of the indexing plate 86.

[0053] The height of the third limiting bar 81 is slightly higher than that of the L-shaped square tube 89, allowing the L-shaped square tube 89 to slide between the frame 1 and the fixed disc 85.

[0054] Multiple L-shaped square tubes 89 are stacked and placed in the L-shaped opening 810 of the rotating disk 87. The indexing plate 86 drives the rotating disk 87 to rotate 90 degrees periodically. The L-shaped opening 810 on the left side of the rotating disk 87 coincides with the L-shaped opening 810 on the left side of the fixed disk 85, so that the L-shaped square tubes 89 fall into the L-shaped opening 810 on the left side of the fixed disk 85. Then, the output shaft of the third cylinder 83 of the continuous pushing assembly shortens, driving the pusher plate 82 to move to the right. The pusher plate 82 moves to the right, causing the L-shaped square tubes 89 in the L-shaped opening 810 on the left side of the fixed disk 85 to fall down. The output shaft of the third cylinder 83 extends, driving the pusher plate 82 to move to the left, pushing the L-shaped square tubes 89 toward the second limiting bar 4.

[0055] After the L-shaped square tube 89 is loaded into the L-shaped opening 810 on the left side of the fixed disc 85, the indexing disc 86 drives the rotating disc 87 to rotate 90 degrees to load the next station. At this time, the empty L-shaped opening 810 can be loaded manually or by a robotic arm.

[0056] A linear module 12 is installed on the lower side of the frame 1. Multiple fixing posts 13 are fixedly installed at the output end of the linear module 12. A strip-shaped opening 14 is provided on the middle side of the frame 1. The fixing posts 13 are slidably connected to the strip-shaped opening 14 through the strip-shaped opening 14.

[0057] The feeding device 7 includes a fourth cylinder 71, a horizontal plate 72, and a finished product feeding trough 73. The fourth cylinder 71 is fixedly installed on the rear side of the frame 1, the horizontal plate 72 is fixedly installed on the output end of the fourth cylinder 71, and the finished product feeding trough 73 is fixedly installed on the front side of the frame 1.

[0058] The output end of the linear module 12 moves to the right, causing the fixed column 13 to move to the right. The fixed column 13 moves to the right, causing the L-shaped square tube 89 to move to the right. After the L-shaped square tube 89 moves a certain distance, the output end of the linear module 12 returns to its initial state. The output end of the fourth cylinder 71 of the feeding device 7 extends, causing the horizontal plate 72 to move forward. The horizontal plate 72 moves forward, pushing the L-shaped square tube 89 forward and pushing the L-shaped square tube 89 into the finished product feeding trough 73.

[0059] The first limiting strip 2 has an irregular opening 15 on its left side, and a waste material discharge trough 16 is fixedly installed on the lower side of the irregular opening 15.

[0060] After the L-shaped square tube 89 is cut by the saw blade 35, the waste material falls into the waste material discharge trough 16.

[0061] Example 3: In some embodiments, such as Figures 1-9 As shown, in a preferred embodiment of the present invention, a method for a continuous bevel sawing device includes the following steps:

[0062] Step 1: Multiple L-shaped square tubes 89 are placed manually or by a robotic arm into the L-shaped openings 810 of the rotating disk 87 of the rotating feeding assembly. The indexing plate 86 drives the rotating disk 87 to rotate 90 degrees periodically. The L-shaped openings 810 on the left side of the rotating disk 87 and the L-shaped openings 810 on the left side of the fixed disk 85 coincide, causing the L-shaped square tubes 89 to fall into the L-shaped openings 810 on the left side of the fixed disk 85. Then, the output shaft of the third cylinder 83 of the continuous pushing assembly shortens, causing the pushing plate 82 to move to the right, pushing the material... The plate 82 moves to the right, causing the L-shaped square tube 89 in the L-shaped opening 810 on the left side of the fixed disc 85 to fall down. The output shaft of the third cylinder 83 extends, driving the pusher plate 82 to move to the left, pushing the L-shaped square tube 89 towards the second limiting bar 4. At this time, the output shaft of the third cylinder 83 is still in the extended state. The output end of the first cylinder 5 extends, driving the pressure plate 6 to move towards the position of the L-shaped square tube 89, pressing the L-shaped square tube 89 at the position of the first limiting bar 2. The L-shaped square tube 89 is fixed at the positions of the first limiting bar 2 and the second limiting bar 4.

[0063] Step 2: The output shaft of the drive motor 33 of the continuous cutting device 3 rotates, driving the gearbox 34, which in turn drives the saw blade 35 to rotate. The output shaft of the second cylinder 36 extends, causing the rotating bracket 32 ​​to rotate to the left. The rotation of the rotating bracket 32 ​​to the left causes the drive motor 33, gearbox 34, and saw blade 35 to rotate to the left. The saw blade 35 cuts the L-shaped square tube 89 fixed on the first limiting bar 2 and the second limiting bar 4. After the L-shaped square tube 89 is cut by the saw blade 35, the waste material falls into the waste material discharge trough 16. After the cutting is completed, the output shaft of the second cylinder 36 shortens, causing the rotating bracket 32 ​​to rotate to the right. The rotation of the rotating bracket 32 ​​to the right causes the drive motor 33, gearbox 34, and saw blade 35 to rotate to the right. The saw blade 35 is lifted, waiting for the next cut. At this time, the output shaft of the third cylinder 83 shortens, waiting for the next feeding.

[0064] Step 3: The output end of the linear module 12 moves to the right, causing the fixed column 13 to move to the right. The fixed column 13 moves to the right, causing the L-shaped square tube 89 to move to the right. After the L-shaped square tube 89 moves a certain distance, the output end of the linear module 12 returns to its initial state. The output end of the fourth cylinder 71 of the feeding device 7 extends, causing the horizontal plate 72 to move forward. The horizontal plate 72 moves forward, pushing the L-shaped square tube 89 forward and pushing it into the finished product feeding slot 73.

9. A method for a continuous bevel sawing apparatus, used in the continuous bevel sawing apparatus of claim 8, characterized in that, Includes the following steps: Step 1: Multiple L-shaped square tubes (89) are placed manually or by a robotic arm into the L-shaped openings (810) of the rotating disk (87) of the rotating feeding assembly. The indexing plate (86) drives the rotating disk (87) to rotate 90 degrees periodically. The L-shaped openings (810) on the left side of the rotating disk (87) and the L-shaped openings (810) on the left side of the fixed disk (85) coincide, causing the L-shaped square tubes (89) to fall into the L-shaped openings (810) on the left side of the fixed disk (85). Then, the output shaft of the third cylinder (83) of the continuous pushing assembly shortens, causing the pusher plate (82) to move to the right. 2) Moving to the right causes the L-shaped square tube (89) in the L-shaped opening (810) on the left side of the fixed disc (85) to fall down. The output shaft of the third cylinder (83) extends and drives the pusher plate (82) to move to the left, pushing the L-shaped square tube (89) towards the second limiting bar (4). At this time, the output shaft of the third cylinder (83) is still in the extended state. The output end of the first cylinder (5) extends and drives the pressure plate (6) to move towards the position of the L-shaped square tube (89), pressing the L-shaped square tube (89) at the position of the first limiting bar (2). The L-shaped square tube (89) is fixed at the positions of the first limiting bar (2) and the second limiting bar (4). Step 2: The output shaft of the drive motor (33) of the continuous cutting device (3) rotates, driving the gearbox (34), which in turn drives the saw blade (35) to rotate. The output shaft of the second cylinder (36) extends, causing the rotating bracket (32) to rotate to the left. The rotation of the rotating bracket (32) to the left drives the drive motor (33), gearbox (34), and saw blade (35) to rotate to the left. The saw blade (35) will move the L-shaped square fixed on the first limiting bar (2) and the second limiting bar (4) to the left. The tube (89) is cut. After the L-shaped square tube (89) is cut by the saw blade (35), the waste falls into the waste discharge trough (16). After the cutting is completed, the output shaft of the second cylinder (36) shortens and drives the rotating bracket (32) to rotate to the right. The rotating bracket (32) rotates to the right and drives the drive motor (33), gearbox (34) and saw blade (35) to rotate to the right. The saw blade (35) is lifted and waits for the next cutting. At this time, the output shaft of the third cylinder (83) shortens and waits for the next feeding. Step 3: The output end of the linear module (12) moves to the right, driving the fixed column (13) to move to the right. The fixed column (13) moves to the right, driving the L-shaped square tube (89) to move to the right. The L-shaped square tube (89) moves to a certain distance, and the output end of the linear module (12) returns to the initial state. The output end of the fourth cylinder (71) of the feeding device (7) extends, driving the horizontal plate (72) to move forward. The horizontal plate (72) moves forward, pushing the L-shaped square tube (89) forward and pushing the L-shaped square tube (89) to the finished product feeding slot (73). The output end of the fourth cylinder (71) returns to the initial position, waiting for the next feeding.
