DETAILED DESCRIPTION The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

[0017] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled.

For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0019] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them.

A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0020] In the description of this embodiment, the terms "up", "down", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] like Figures 1 to 8 As shown, it shows a material carrying conveyor rack in one embodiment of the present invention, comprising a base 1 and a bottom frame 101; The top of the base frame 101 is fixedly connected to multiple support frames 2, and the tops of the multiple support frames 2 are commonly fixedly connected to a load-bearing plate a201. One side of the load-bearing plate a201 is rotatably connected to the load-bearing plate b202 through a hinge shaft. The load-bearing plates a201 and b202 are arranged in a V shape as a whole. The inner cavities of the load-bearing plates a201 and b202 are both rotatably connected to guide wheels 203. The inner cavity of the base frame 101 is movably connected to a first cylinder 204. The top end of the telescopic rod of the first cylinder 204 is hinged to the bottom surface of the load-bearing plate b202. In some examples, the base frame 101 fixes the carrying plate a201 through the support frame 2, and the carrying plate b202 is hinged to the a plate and driven by the first cylinder 204 to form a reversible V-shaped carrying platform; The guide wheel 203 in the inner cavity of the bearing plate assists the tube in rolling, and the cylinder drives the b plate to flip and change the shape of the bearing surface (V-shaped → inclined surface); The V-shaped structure can center and position pipes of different diameters, and the guide wheel 203 can reduce the pushing resistance; The cylinder drives the load-bearing plate b202 to flip, so that the pipe switches from a static load-bearing state to an inclined rolling state, realizing the "load-release" automation.

[0023] For example, Figure 4As shown, after the pipe is cut, it rolls out of the supporting platform along the guide wheel 203 by its own gravity or pushing force, replacing manual unloading.

[0024] like Figure 4-6 As shown, the inner cavity of the support frame 2 is rotatably connected to a material receiving assembly, which includes a material receiving plate 3, which is rotatably connected to the inner cavity of the support frame 2. The material receiving plate 3 is L-shaped, and the inner cavity of the material receiving plate 3 is rotatably connected to a rotating shaft 301. The surface of the rotating shaft 301 is fixedly connected to a buffer plate 302. Both ends of the rotating shaft 301 are fixedly connected to a gear 303, and both sides of the material receiving plate 3 are movably connected to a rack 304. The material receiving assembly also includes two connecting plates 305, which are fixedly connected to both sides of the material receiving plate 3. A compression spring 306 is fixedly connected between the connecting plate 305 and the rack 304. An extrusion plate 307 is fixedly connected to one side of the support frame 2. The position of the extrusion plate 307 corresponds to that of the rack 304, and the contact surfaces of the two are both provided with an extrusion slope 308. The inner cavity of the support frame 2 is movably connected to a second cylinder 309, and the top of the telescopic rod of the second cylinder 309 is hingedly matched with the bottom surface of the material receiving plate 3; The rack 304 and the gear 303 are meshed together, one end of the compression spring 306 is fixedly connected to one end of the connecting plate 305, and the other end of the compression spring 306 is fixedly connected to the top of the rack 304. A groove 4 is formed on the surface of the buffer plate 302. In some examples, the L-shaped receiving plate 3 is driven to rotate by the second cylinder 309, and the built-in rotating shaft 301 is connected to the buffer plate 302, and the buffer plate is dynamically exposed through the gear 303-rack 304 transmission; The inclined surface 308 of the extrusion plate 307 cooperates with the compression spring 306 to control the movement of the rack 304 and the reset of the buffer plate; The vertical section of the splice plate 3 blocks the inertial sliding of the pipe, and the groove 4 of the horizontal section of the buffer plate fits the outer circle of the pipe. The impact energy is absorbed by the elastic deformation of the compression spring 306, and the port cracking rate is reduced from 15% to below 1%; The expansion and hiding of the buffer plate 302 depends on the transmission of the rack 304 and the gear 303 when the receiving plate 3 rotates and the energy storage of the compression spring 306, without the need for additional motors or sensors, thus improving reliability; The L-shaped structure integrates the buffer function under the carrier, which occupies less space than traditional buffer devices and is suitable for narrow production lines; For example, Figure 6 As shown, an extrusion slope 308 is provided on the contact surface between the extrusion plate 307 on one side of the support frame 2 and the rack 304. When the receiving plate 3 is reset, the rack 304 slides along the slope, driving the buffer plate 302 to hide in the inner cavity of the receiving plate 3.

[0025] like Figure 2 、 Figure 7As shown, the top of the base 1 is slidably connected to the body 5, the inner cavity of the body 5 is provided with a cutting mechanism, one end of the body 5 is bolted to a drive motor 501, and the output end of the drive motor 501 is transmission-connected to the cutting mechanism; Both ends of the body 5 are fixedly connected to the connecting ring 6. The inner cavity of the connecting ring 6 is rotatably connected to four clamping arms 601. The surfaces of the four clamping arms 601 are mounted with limit rings 602. Adjacent clamping arms 601 are slidably hinged by connecting rods 603. One end of the body 5 is movably connected to the third cylinder 604. The top end of the telescopic rod of the third cylinder 604 is hingedly engaged with the inner cavity of the clamping arm 601. In some examples, the machine body 5 is equipped with a driving motor 501 to drive the cutting mechanism, and the clamping arms 601 at both ends are controlled by a third cylinder 604 and are linked to be retracted / released through a connecting rod 603; The clamping arm 601 fixes the pipe and the driving motor 501 cuts at high speed. The verticality error of the cut surface is ≤0.5°, replacing manual positioning cutting. After the cutting is completed, the cylinder is depressurized, the clamping arm 601 is released, and the pipe is automatically separated from the mother pipe by the rear end thrust or gravity, avoiding damage to the port caused by manual pulling; For example, Figure 7 As shown, adjacent clamping arms 601 are slidably hinged by connecting rods 603, and the top end of the telescopic rod of the third cylinder 604 is hinged to the inner cavity of the clamping arm 601 to achieve synchronous opening and closing; like Figure 2 、 Figure 7 As shown, both ends of the body 5 are fixedly connected to a support plate 7, the inner cavity of the support plate 7 is slidably connected to a guide rod 701, one end of the guide rod 701 is fixedly connected to a mounting bracket 702, the inner cavity of the mounting bracket 702 is rotatably connected to a roller 703, the top of the support plate 7 is fixedly connected to a first sleeve 704, the inner cavity of the first sleeve 704 is threadedly connected to a first threaded rod 705, and one end of the first threaded rod 705 is fixedly connected to the bottom of the mounting bracket 702; A second sleeve 8 is fixedly connected to the top of the base 1. A second threaded rod 801 is threadedly connected to the inner cavity of the second sleeve 8. One end of the second threaded rod 801 is fixedly connected to a mounting plate 802. Auxiliary wheels 803 are rotatably connected to both ends of the mounting plate 802. The surface of the mounting bracket 702 slides with the inner cavity of the auxiliary wheel 803. One end of the first sleeve 704 and the second sleeve 8 are both sleeved with a threaded ring 9, and a plurality of push rods 901 are fixedly connected to the surface of the threaded ring 9; In some examples, by rotating the threaded ring 9 , the support plate 7 adjusts the height of the roller 703 via the first sleeve 704 - threaded rod 705 , and the base auxiliary wheel 803 is adjusted synchronously via the second sleeve 8 ; The height of the roller 703 and auxiliary wheel 803 is continuously adjustable, which is compatible with the transportation and positioning of pipes of different diameters, solving the problem that traditional equipment can only handle a single specification; The roller 703 and auxiliary wheel 801 are coated with polytetrafluoroethylene, and cooperate with the guide rod 701 to slide linearly, reducing the conveying resistance and making it suitable for long-distance pipe transportation; "like Figure 7 As shown, the inner cavity of the first sleeve 704 is threadedly connected to the first threaded rod 705, one end of which is fixed to the mounting bracket 702. Rotating the threaded ring 9 can drive the threaded rod to move up and down, thereby adjusting the height of the roller 703.

[0026] Carrying system: The carrying plate a201 and the carrying plate b202 form a V-shaped carrying platform, the inner cavity guide wheel 203 assists in pipe transportation, and the first cylinder 204 drives the carrying plate b to flip.

[0027] Material receiving buffer system: The L-shaped material receiving plate 3 is linked by the second cylinder 309 and the gear 303 and rack 304 mechanism to realize the dynamic exposure and hiding of the buffer plate 302, and cooperate with the compression spring 306 to absorb impact.

[0028] Cutting and clamping system: The machine body 5 has a built-in cutting mechanism, which controls the clamping arm 601 to clamp the pipe through the third cylinder 604 and drives the motor 501 to realize cutting power output.

[0029] Pipe positioning and cutting stage Transport and positioning: The entire plastic pipe is transported to the inner cavity of the body 5 through the roller 703 on the base 1.

[0030] Clamping and fixing: The telescopic rod of the third cylinder 604 extends, and drives the four clamping arms 601 to retract toward the center through the connecting rod 603. The limiting ring 602 on the surface of the clamping arm is close to the outer wall of the pipe to achieve rigid fixation.

[0031] Cutting execution: the drive motor 501 is started, and the cutting mechanism is driven to rotate at high speed through the transmission mechanism. At the same time, the body 5 slides along the base 1 (controlled by an external drive device), so that the cutting mechanism is fed along the axis of the pipe to complete the fixed-length cutting.

[0032] Pipe pushing and loading stage Cutting and separation: After the cutting is completed, the third cylinder 604 releases pressure, the clamping arm 601 is released, and the body 5 continues to move forward. The uncut pipe is squeezed by its own gravity or the rear-end pushing mechanism, so that the cut pipe section is separated from the mother pipe and rolls along the guide wheel 203 to the V-shaped bearing platform (the bearing plate a201 and the bearing plate b202 form an angle of 60°-90°).

[0033] In-place detection: The guide wheel 203 has a built-in speed sensor. When it detects that the pipe has stopped rolling, it is determined that the pipe is completely in place and the subsequent material connection components are triggered.

[0034] Linkage between receiving plate and buffer plate The receiving plate pre-action: the telescopic rod of the second cylinder 309 extends, pushing the receiving plate 3 to rotate counterclockwise (initially rotate from the vertical state).

[0035] Rack and pinion linkage: When the receiving plate 3 rotates, the racks 304 on both sides move with the connecting plate 305. When the racks are separated from the top of the extrusion plate 307, the compression spring 306 releases the stored energy and pushes the racks 304 to move downward.

[0036] The buffer plate is exposed: the rack 304 is meshed with the gear 303 to drive the rotating shaft 301 to rotate 90° clockwise, so that the buffer plate 302 is rotated out of the inner cavity of the receiving plate 3, and the groove 4 on its surface fits the outer circle of the pipe.

[0037] Loading plate flipping and pipe rolling buffer The V-shaped platform disintegrates: the telescopic rod of the first cylinder 204 extends, pushing the bearing plate b202 to rotate clockwise around the hinge axis, and the V-shaped bearing platform becomes an inclined plane. Under the action of gravity, the pipe rolls along the guide wheel 203 toward the material receiving plate 3.

[0038] Cushioning and energy absorption: Buffering: The front end of the pipe contacts the buffer plate 302, the groove 4 limits the rolling direction of the pipe, and the buffer plate 302 rotates slightly counterclockwise with the rotating shaft 301, and absorbs the initial impact through the elastic deformation of the compression spring 306.

[0039] Reset stage and blanking preparation The supporting plate is reset: the first cylinder 204 is depressurized, the supporting plate b202 returns to the V-shaped position counterclockwise, and the guide wheel 203 returns to the horizontal conveying state.

[0040] The receiving plate is reset: the telescopic rod of the second cylinder 309 is retracted, and the receiving plate 3 rotates clockwise to reset to a vertical state. During this process, the rack 304 contacts the extrusion slope 308 of the extrusion plate 307, and the rack overcomes the resistance of the compression spring 306 and moves upward, driving the buffer plate 302 to rotate and hide in the inner cavity of the receiving plate.

[0041] Low-height blanking: The bottom of the vertical section of the splicing plate 3 is ≤200mm above the ground. The pipe rolls out slowly along the guide groove on the inner side of the splicing plate to avoid impact from falling from a high altitude (equivalent falling height <30cm, impact acceleration <5g).

[0042] Cycle preparation and precision adjustment Guide wheel calibration: By rotating the threaded ring 9 on the first sleeve 704 and the second sleeve 8, the height of the guide rod 701 and the auxiliary wheel 803 can be adjusted to adapt to pipes of different diameters.

[0043] Adaptive clamping force: The pressure sensor of the third cylinder 604 provides real-time feedback on the clamping force, and the PLC system automatically adjusts the air pressure to avoid deformation of thin-walled pipes.

[0044] Core innovation working principle Rack and pinion linkage buffer mechanism: By driving the inclined surface of the extrusion plate 307 and resetting the energy stored in the compression spring 306, the buffer plate 302 can be passively deployed and actively reset without the need for an additional power source. The response time is ≤0.3s, solving the lag problem of traditional buffer devices.

[0045] L-shaped splice plate for low-impact blanking: By utilizing the geometric characteristics of the vertical section blocking and the horizontal section buffering of the connecting plate 3, the height of the pipe landing point is reduced from 1 to 2 meters in the traditional solution to below 200 mm.
