Description

Technical Field

[0001] This invention relates to the field of plastic pipe stacking technology, specifically a plastic pipe cutting and stacking machine. Background Technology

[0002] Plastic pipes are generally made from synthetic resin, namely polyester, with the addition of stabilizers, lubricants, plasticizers, etc., and are processed by extrusion in a pipe-making machine using a "plastic" method. They are mainly used for piping in water supply systems, drainage, ventilation, and sewage systems in buildings, underground drainage systems, rainwater pipes, and conduits for electrical wiring installations.

[0003] In the production and processing of plastic pipes, the raw materials need to be melted and mixed before production. Then, under the action of the extruder, the plastic raw materials that need to be heated and melted are extruded through the mold and cooled and shaped. Next, they are cut and trimmed to meet the product requirements and size standards. After the plastic pipe quality inspection (appearance quality, dimensional accuracy, mechanical properties, etc.) is completed, it is packaged and stored.

[0004] The patent document with publication number CN111674936A describes a plastic pipe cutting and stacking machine. By using the elastic potential energy formula of a spring, the superposition of the weight of each layer of plastic pipes causes the stacking platform to descend by the same height each time, so that the next layer of plastic pipes can be stacked. The elastic potential energy of the torsional spring causes the stacking platform to slowly rise after the plastic pipes are transported away. The screw and slider structure causes the electric saw to rise and cut the plastic pipes. This method is safer and reduces manual labor.

[0005] However, in the process of implementing the above technical solution, the following technical problems were found:

[0006] Existing plastic pipe cutting and stacking machines utilize springs to provide support at the bottom of the stacking platform and control the platform's descent height using the weight of the plastic pipes. However, as the spring's compression increases, the force required to overcome its deformation changes, making it difficult to ensure that the stacking platform descends to the same height each time, ultimately affecting the effectiveness of stacking plastic pipes layer by layer. Summary of the Invention

[0007] To overcome the shortcomings of existing plastic pipe cutting and stacking machines, where the force required to overcome deformation changes with increasing spring compression, making it difficult to ensure consistent descent heights of the stacking platform and ultimately affecting the layer-by-layer stacking effect of plastic pipes, this application provides a plastic pipe cutting and stacking machine. This machine uses a receiving plate supported by four multi-stage hydraulic push rods at the bottom of the guide plate to receive plastic pipes. Both the guide plate and the receiving plate are inclined, facilitating the arrangement of plastic pipes to one side. After multiple plastic pipes are arranged on the top of one receiving plate, the four multi-stage hydraulic push rods simultaneously retract a distance, allowing the plastic pipes on the top of the receiving plate to be supported at the bottom of the receiving plate supplemented from the feed plate base to the bottom of the guide plate. Four limiting strips on the stacking components are then inserted into the four positioning slots of one receiving plate, facilitating the stacking of multiple plastic pipes and resulting in higher efficiency.

[0008] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0009] A plastic pipe cutting and stacking machine includes a receiving structure, a guiding structure, and a receiving plate, wherein the guiding structure is disposed on the top of one end of the receiving structure;

[0010] The receiving structure includes a plate feeding base frame, a receiving frame is machined on one side of the plate feeding base frame, a base plate is machined on the bottom of the receiving frame, two multi-stage hydraulic push rods are assembled and connected to both sides of the base plate, and support strips are assembled and connected to the top of the four multi-stage hydraulic push rods. The guiding structure includes two symmetrically arranged limiting brackets, a common guiding plate is machined between the middle of the two limiting brackets, and a guiding platform is machined on the top of the two limiting brackets.

[0011] The plastic tube rolls through the inside of the guide platform to the top of the guide plate. The receiving plate is conveyed from the top of the feeding base frame to one side of the receiving frame, and the plastic tube is received at the bottom of the guide plate.

[0012] In one possible implementation, the bottom end of the receiving plate is simultaneously abutted against the top ends of the four support plates. Both the guide plate and the receiving plate are inclined. The plastic tube rolls from one end of the guide plate near the limiting bracket to the other end, and the plastic tube rolls from one end of the receiving plate near the receiving frame to the other end.

[0013] In one possible implementation, the substrate has a receiving slot inside, a retaining ring is machined at the bottom of the substrate, and a stacking component is movably connected to the inner side of the retaining ring. The stacking component includes a stacking plate, and limit inserts are machined at the four corners of the top of the stacking plate.

[0014] In one possible implementation, positioning slots are machined inside the four corners of the receiving plate, multiple plastic tubes are arranged on the top of multiple receiving plates, the multiple receiving plates are stacked up and down, and the four limiting strips are respectively inserted into the four positioning slots.

[0015] In one possible implementation, both the receiving plate and the guide plate have their long sides turned upwards, and the length of the receiving plate is greater than the length of the guide plate, with the length difference being greater than the outer diameter of the plastic tube.

[0016] In one possible implementation, two symmetrical second supports are provided inside both sides of the plate feeding base frame. The second supports have an L-shaped cross-section, and multiple support rollers are provided between the two second supports. One side of the bottom of the second support is assembled to the bottom of the plate feeding base frame, and the receiving plate is movably connected to the top of the support rollers.

[0017] In one possible implementation, the top of both sides of the plate feeding frame is fitted with a first bracket, the first bracket has a U-shaped cross section, and the inner side of the first bracket is provided with a plurality of guide rollers, the surface of the guide rollers being in contact with the long side surface of the receiving plate.

[0018] In one possible implementation, the guide platform has a feeding slot machined inside, the feeding slot having a right-angled trapezoidal cross-section, and a limit stop is assembled and connected to the top of the guide platform. The plastic tube rolls along the inclined surface of one side of the feeding slot towards the bottom of the limit stop.

[0019] In one possible implementation, two symmetrical positioning blocks are machined on the top of one end of the guide platform. The cross-section of the positioning blocks is a right trapezoid. Multiple sets of the two symmetrical positioning blocks are provided, and the plastic tube is movably connected between the two positioning blocks.

[0020] In one possible implementation, a conveyor belt is provided inside one end of the guide platform, the outer wall of the plastic tube is in contact with the top surface of the conveyor belt, and the conveyor belt transports the plastic tube from between two positioning blocks into the interior of the feed trough.

[0021] The beneficial effects of this application are as follows:

[0022] Firstly, in this solution, plastic tubes are picked up by a receiving plate supported by four multi-stage hydraulic push rods at the bottom of the guide plate. Both the guide plate and the receiving plate are inclined, which helps to arrange the plastic tubes to one side. After the top of one receiving plate has completed the arrangement of multiple plastic tubes, the four multi-stage hydraulic push rods retract a certain distance simultaneously, so that the plastic tubes at the top of the receiving plate are supported on the bottom of the receiving plate supplemented from the bottom of the guide plate base frame to the bottom of the guide plate. The four limiting strips on the stacking parts are respectively inserted into the four positioning slots of one receiving plate, which is conducive to the arrangement and stacking of multiple plastic tubes and has high efficiency.

[0023] Secondly, in this solution, the cut and trimmed plastic tubes are transported to the top of the guide platform by a conveyor belt. The plastic tubes are then restricted by two symmetrical positioning blocks to the top of the unloading trough, where they fall onto the guide plate between the two limiting brackets. During this process, the plastic tubes are transported continuously, which facilitates the transfer and replenishment of the receiving plate from the top of the feeding frame to the bottom of the guide plate, as well as the movement of the receiving plate carrying multiple plastic tubes to the bottom. This is simple and convenient. Attached Figure Description

[0032] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0033] Example 1:

[0034] This embodiment describes the specific structure of a plastic pipe cutting and stacking machine, see details below. Figures 1-7 As shown, it includes a receiving structure 4, a guiding structure 1 and a receiving plate 3 disposed at the top of one end of the receiving structure 4. The receiving structure 4 includes a feeding base frame 402. A receiving mating frame 403 is machined on one side of the feeding base frame 402. A base plate 406 is machined on the bottom of the receiving mating frame 403. Two multi-stage hydraulic push rods 405 are assembled and connected to both sides of the base plate 406. Support strips 404 are assembled and connected to the top of the four multi-stage hydraulic push rods 405.

[0035] In this way, by extending the multi-stage hydraulic push rod 405, the support strip 404 at its top is supported on the bottom of the receiving plate 3, and the receiving plate 3 is set between the receiving frame 403 and the guiding structure 1, which is conducive to the arrangement of multiple plastic tubes 2 on the top of the receiving plate 3.

[0036] like Figure 1 and Figure 6 As shown, the substrate 406 has a receiving slot 6 inside, and a retaining ring 411 is processed on the bottom of the substrate 406. The inner side of the retaining ring 411 is movably connected to the stacked member 407.

[0037] like Figure 2 As shown, the material guiding structure 1 includes two symmetrically arranged limiting brackets 103, with the same material guiding plate 101 machined between the middle of the two limiting brackets 103, and a material guiding platform 102 machined on the top of the two limiting brackets 103.

[0038] Among them, such as Figure 1As shown, the length of the receiving plate 3 is greater than the length of the guide plate 101, and the length difference is greater than the outer diameter of the plastic tube 2. When the plastic tube 2 rolls through the inside of the guide plate 102 to the top of the guide plate 101, the plastic tube 2 can fall from the gap between the guide plate 101 and the receiving frame 403 to the top of the receiving plate 3, and the plastic tube 2 is received at the bottom of the guide plate 101.

[0039] Secondly, such as Figure 5 As shown, the bottom end of the receiving plate 3 is simultaneously attached to the top end of the four support plates 404, and both the guide plate 101 and the receiving plate 3 are inclined. When the plastic tube 2 rolls from one end of the guide plate 101 near the limiting bracket 103 to the other end, it can fall from the guide plate 101 and the receiving frame 403 onto the top of the receiving plate 3, and roll from one end of the receiving plate 3 near the receiving frame 403 to the other end.

[0040] Meanwhile, the receiving plate 3 is conveyed from the top of the feeding base frame 402 to one side of the receiving frame 403. Plastic tubes 2 can be arranged on the top of one receiving plate 3. After the receiving plate 3 is moved down by the control of the multi-stage hydraulic push rod 405, another receiving plate 3 is laid on top of the receiving plate 3 to carry out the subsequent arrangement of plastic tubes 2.

[0041] In addition, such as Figure 1 As shown, both the receiving plate 3 and the guide plate 101 have their long sides flipped up to the top. When the plastic tube 2 rolls to the top of the receiving plate 3 on the guide plate 101, it can restrict the plastic tube 2 from moving left and right on the top of the guide plate 101 or the receiving plate 3.

[0042] Furthermore, in order to allow multiple receiving boards 3 to be stacked vertically and to smoothly complete the transfer process, such as... Figure 1 As shown, the stacking component 407 includes a stacking plate 4071. Limiting inserts 4072 are processed at the four corners of the top of the stacking plate 4071. By processing positioning slots 5 inside the four corners of the receiving plate 3, when multiple plastic tubes 2 are arranged on the top of multiple receiving plates 3, and the four limiting inserts 4072 are respectively inserted into the four positioning slots 5, the receiving plate 3 can be mounted between the four limiting inserts 4072, and the plastic tubes 2 are prevented from sliding off the top of the receiving plate 3, which is beneficial for stacking multiple receiving plates 3.

[0043] Meanwhile, after the stacking component 407 completes the receiving work of multiple receiving plates 3 and supports their stacking, it can form a support at the bottom of the stacking component 407 with the help of transportation tools such as flatbed trucks, trucks, and forklifts. After the top of the stacking component 407 is separated from the bottom of the base plate 406, the stacking component 407 is pulled to one side, so that the limiting insert 4072 passes through the four support strips 404 and the bottom receiving plate 3 is separated from the top of the support strip 404.

[0044] Furthermore, to facilitate the receiving plate 3 that will soon participate in receiving the plastic tube 2, it is fed between the receiving mating frame 403 and the limiting bracket 103, such as... Figure 1 and Figure 4 As shown, two symmetrical second supports 410 are provided inside both sides of the plate feeding base frame 402. By setting the cross section of the second support 410 to L-shape, one side of the bottom of the second support 410 can be assembled and connected to the bottom of the plate feeding base frame 402. Multiple support rollers 401 are provided between the two second supports 410, thereby reducing the resistance when the receiving plate 3 moves on the top of the support rollers 401.

[0045] Meanwhile, to ensure that the receiving plate 3 can accurately pass through the inside of the receiving mating frame 403 from the top of the feeding base frame 402 and move to the bottom of the four support plates 404, such as Figure 4 As shown, the top of both sides of the plate feeding base frame 402 is equipped with a first bracket 409. By setting the cross section of the first bracket 409 to a U-shape, multiple guide rollers 408 are provided on the inner side of the first bracket 409. When the receiving plate 3 moves on top of the multiple support rollers 401, the surface of the guide rollers 408 can be made to fit with the long side surface of the receiving plate 3, thus correcting the moving angle of the receiving plate 3.

[0046] Example 2:

[0047] Based on Example 1, this example describes the specific structure of the material guiding structure 1. The material guiding platform 102 has a material discharge slot 105 machined inside, and the top of the material guiding platform 102 is assembled with a limit stop 104.

[0048] The cross-section of the feeding slot 105 is a right trapezoid. When the cut plastic tube 2 is transported to the top of the guide table 102, the plastic tube 2 falling into the feeding slot 105 can roll along the inclined surface on one side of the limit stop 104 to the bottom.

[0049] Secondly, in order for the plastic tube 2 to be conveyed to the top of the discharge trough 105, such as Figure 3 As shown, a conveyor belt 106 is installed inside one end of the guide platform 102. By making the outer wall of the plastic tube 2 fit against the top surface of the conveyor belt 106, the conveyor belt 106 can transport the plastic tube 2 from between the two positioning blocks 107 into the inside of the feed trough 105.

[0050] Meanwhile, in order to limit the plastic tube 2 from rolling on top of the conveyor belt 106, and to allow the plastic tube 2 to be controlled by the conveyor belt 106 to move directly above the discharge trough 105, such as... Figure 2 and Figure 3As shown, the guide table 102 has a feeding slot 105 machined inside. The top of the guide table 102 is assembled with a limit stop 104. By setting the cross section of the feeding slot 105 to a right trapezoid, the plastic tube 2 rolls along the inclined surface of one side of the feeding slot 105 towards the bottom of the limit stop 104.

[0051] Specifically, when using this plastic tube cutting and stacking machine to arrange and stack plastic tubes 2:

[0052] First, the cut and trimmed plastic tube 2 is transported to the top of the guide platform 102 by the conveyor belt 106, and the plastic tube 2 is restricted to roll on the top of the guide platform 102 by two symmetrical positioning blocks 107. When the plastic tube 2 is transported to the top of the discharge slot 105, the plastic tube 2 rolls along the inclined surface on one side to the bottom of the limiting bracket 104 and falls on the guide plate 101 between the middle of the two limiting brackets 103.

[0053] Then, controlled by the inclined guide plate 101, the plastic tube 2 rolls from the top of the guide plate 101 toward one side of the receiving frame 403, and falls into the top of the receiving plate 3 from the gap between the receiving frame 403 and the guide plate 101. Guided by the inclined state of the receiving plate 3, it rolls from one side to the other, which is beneficial for multiple plastic tubes 2 to be arranged on the top of the same receiving plate 3.

[0054] Next, after the arrangement of multiple plastic tubes 2 is completed on the top of a receiving plate 3, the multi-stage hydraulic push rod 405 retracts quantitatively, causing the support bar plate 404 supported on the bottom of the receiving plate 3 to move to the bottom, releasing the receiving plate 3 to the bottom, so that the four limiting inserts 4072 on the stacking piece 407 are respectively inserted into the four positioning slots 5 of a receiving plate 3, restricting the plastic tubes 2 from rolling off the top of the receiving plate 3;

[0055] Meanwhile, the receiving plate 3 at the top of the feeding base frame 402 is supported by multiple support rollers 401 and guided by multiple guide rollers 408. It passes through the interior of the receiving and mating frame 403 and fills the gap between the limiting bracket 103 and the receiving and mating frame 403. It is supported by multiple plastic tubes 2 at the top of the lower receiving plate 3. The subsequent receiving work of plastic tubes 2 is carried out at the bottom of the guide plate 101. In this way, multiple receiving plates 3 can be used to complete the arrangement and stacking of multiple plastic tubes 2, which is highly efficient.

[0056] Finally, after the stacking component 407 has completed the receiving work of multiple receiving plates 3 and supported their stacking, it can be supported at the bottom of the stacking component 407 by means of transport tools such as flatbed trucks, trucks, and forklifts. After the top of the stacking component 407 is separated from the bottom of the base plate 406, the stacking component 407 is pulled to one side, so that the limiting insert 4072 passes through the four support strips 404 and the bottom receiving plate 3 is separated from the top of the support strip 404, which is conducive to the transfer of multiple stacked plastic tubes 2.

[0057] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
