Description

Technical Field

[0001] This invention relates to the field of plastic pipe manufacturing technology, and in particular to a multifunctional conveying device for plastic pipe manufacturing. Background Technology

[0002] In the fields of plastic pipe production, warehousing, and logistics, cut plastic pipes are typically neatly stacked on shelves for transportation, storage, or subsequent processing. Traditional plastic pipe laying methods often rely on manual operation or simple mechanical auxiliary equipment, such as using overhead cranes or hoists to lift the produced plastic pipes to the shelves and then drop them directly onto the shelves. However, when pipes fall freely from a height onto the shelf floor or onto already stacked pipes, they generate severe impacts and collisions. These impacts can easily cause problems such as pipe deformation, scratches on the surface coating, and damage to the joints, seriously affecting the quality and service life of the pipes. Summary of the Invention

[0003] To overcome the drawbacks of pipes falling freely from a height onto the shelf floor or stacked pipes, which can cause severe impacts and collisions, leading to pipe deformation, surface coating damage, and joint damage, thus seriously affecting pipe quality and service life, this invention provides a multifunctional conveying device for plastic pipe production.

[0004] Technical Solution: A multifunctional conveying device for producing plastic pipes includes a base frame and a receiving plate fixed to the base frame; it also includes a baffle; a baffle is fixed to the rear of the receiving plate; two symmetrically arranged chain conveyors are fixed to the base frame; several U-shaped lifting plates are equidistantly fixed to the chain of each chain conveyor, the U-shaped lifting plates being used to lift the plastic pipes; an inclined guide surface is provided on the upper part of the base frame; two symmetrically arranged motors are fixed to the base frame; a pull rope is wound on the output shaft of each motor; each pull rope slides in a groove opened in the base frame; an electromagnetic rod is fixed to the common end of the two pull ropes; two symmetrically arranged mounting plates are fixed to the base frame; a motor is fixed to each mounting plate; a pull rope is wound on the output shaft of each motor; a metal rod is fixed to the common end of the two pull ropes; the electromagnetic rod and the metal rod are attracted together; each pull rope slides in a groove opened in the corresponding mounting plate.

[0005] More preferably, the U-shaped lifting plate is provided with an arc-shaped part.

[0006] More preferably, it also includes a limiting plate; each mounting plate is fixedly connected to a limiting plate; the limiting plate and the guide surface are arranged in a trumpet shape.

[0007] More preferably, it also includes industrial vision cameras; several vertically distributed industrial vision cameras are fixed at equal intervals on the base frame.

[0008] More preferably, it also includes a connecting rod and a baffle; a connecting rod is fixed to each end of the electromagnetic rod; the connecting rod passes through the metal rod, and the through hole of the metal rod is larger than the diameter of the connecting rod; a baffle is connected to the upper part of each connecting rod.

[0009] More preferably, it also includes a pin that is inserted into the baffle and the connecting rod; the baffle and the connecting rod are slidably connected; and a number of insertion holes are equidistantly arranged on the connecting rod.

[0010] More preferably, it also includes an electric push rod and an electric clamp; two symmetrically arranged electric push rods are fixedly connected to the base frame; and an electric clamp is fixedly connected to the telescopic end of each electric push rod.

[0011] More preferably, the clamping plate of the electric clamp is equipped with anti-slip strips.

[0012] More preferably, it also includes an electric push rod II and a push plate; an electric push rod II is fixedly connected to each mounting plate; and a push plate is fixedly connected to the telescopic end of each electric push rod II.

[0013] More preferably, sponge pads are provided on both sides of the two push plates facing each other.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention first blocks the plastic pipe between the guide surface and the mounting plate by pulling rope two, then lowers the plastic pipe to a position near the bottom of the shelf or where pipes have been placed, and then lets the plastic pipe between pulling rope one and pulling rope two roll down and lay on the bottom of the shelf (or the plastic pipe that has been placed). The plastic pipe only falls from a height close to the bottom of the shelf or where pipes have been stacked, avoiding the plastic pipe falling from a high position and reducing the risk of damage to the plastic pipe.

[0015] 2. This invention ensures that the gap between the electromagnetic rod and the metal rod is only wide enough for one plastic pipe to pass through, allowing the plastic pipes to roll down one by one. This prevents all the plastic pipes between the first and second pull ropes from rolling down after the electromagnetic rod separates from the metal rod, thus avoiding the risk of damage to the uppermost plastic pipe due to its excessive descent height.

[0016] 3. This invention uses two push plates to align the left and right sides of each plastic pipe before stacking them on a shelf. This ensures that the plastic pipes are aligned on both sides after being placed on the shelf, resulting in a neater arrangement of the plastic pipes. Attached Figure Description

Figures 1-5 As shown, it includes a base frame 1 and a support plate 2; the support plate 2 is welded onto the base frame 1; It also includes a baffle 3, a chain conveyor 4, a U-shaped lifting plate 5, a motor 6, a pull rope 7, an electromagnetic rod 8, a mounting plate 9, a second motor 10, a second pull rope 11, and a metal rod 12; a baffle 3 is welded to the rear of the receiving plate 2; two chain conveyors 4 are fixedly mounted on the base frame 1 in a symmetrical arrangement; three U-shaped lifting plates 5 are fixedly mounted equidistantly on the chain of each chain conveyor 4; an inclined guide surface 101 is provided on the upper part of the base frame 1; two motors 6 are bolted to the base frame 1 in a symmetrical arrangement; each motor 6 has an output shaft Each pull rope 7 is wound around a base frame 1; each pull rope 7 slides in a groove opened in the base frame 1; the ends of the two pull ropes 7 are fixedly connected to an electromagnetic rod 8; two mounting plates 9 are welded to the base frame 1 and are arranged symmetrically on the left and right; a motor 2 10 is bolted to each mounting plate 9; a pull rope 2 11 is wound around the output shaft of each motor 2 10; the ends of the two pull ropes 2 11 are fixedly connected to a metal rod 12; the electromagnetic rod 8 and the metal rod 12 are attracted together; each pull rope 2 11 slides in the groove of the corresponding mounting plate 9.

[0021] To prevent damage to the plastic pipe, the U-shaped lifting plate 5 is provided with an arc-shaped part 501.

[0022] It also includes a limiting plate 13; a limiting plate 13 is welded to the front side of each mounting plate 9; the limiting plate 13 and the guide surface 101 are arranged in a trumpet shape, and the limiting plate 13 is used to guide the plastic pipe to roll down between the guide surface 101 and the mounting plate 9.

[0023] It also includes industrial vision cameras 26; three vertically distributed industrial vision cameras 26 are fixed at equal intervals on the rear side of the base frame 1. The industrial vision cameras 26 are used to monitor the position of the plastic pipe.

[0024] It also includes a connecting rod 21 and a baffle 22; a connecting rod 21 is welded to the left end and the right end of the electromagnetic rod 8 respectively; the connecting rod 21 passes through the metal rod 12, and the through hole of the metal rod 12 is larger than the diameter of the connecting rod 21; a baffle 22 is connected to the upper part of each connecting rod 21.

[0025] It also includes a pin 23; a baffle 22 is slidably connected to the connecting rod 21; a pin 23 is inserted between the baffle 22 and the connecting rod 21; and several insertion holes are equidistantly arranged on the connecting rod 21.

[0026] It also includes an electric push rod 24 and an electric clamp 25; two electric push rods 24 are fixedly mounted on the base frame 1 and are arranged symmetrically on the left and right; each electric push rod 24 has an electric clamp 25 fixedly mounted on its telescopic end, and the electric clamp 25 is used to clamp the pull rope 7 and the pull rope 11.

[0027] To facilitate clamping of pull rope 1 7 and pull rope 2 11, anti-slip strips are provided on the clamping plate of the electric clamp 25.

[0028] by Figure 1 Using the viewing angle as a reference, with the side where the base frame 1 is located as the front side, the base frame 1 is installed at the end of the plastic pipe production line.

[0029] In use, place the shelf 14 behind the base frame 1, energize the electromagnetic rod 8 to generate suction force to firmly adhere to the metal rod 12. When the plastic pipe production line starts, the cut plastic pipes are conveyed to the receiving plate 2 and intercepted by the baffle 3 on the receiving plate 2. The chain conveyor 4 is then started. Using a right-to-left view as a reference, the chain of the chain conveyor 4 moves clockwise. The chain of the chain conveyor 4 drives the U-shaped lifting plate 5 to move clockwise. As the U-shaped lifting plate 5 moves, it lifts the plastic pipes... The material pipe is lifted upwards. After passing the highest point, the plastic pipe rolls down between the guide surface 101 and the mounting plate 9 and is blocked by the pull rope 11. When the space between the guide surface 101 and the mounting plate 9 is full of plastic pipe, the control motor 6 rotates to release the pull rope 7 and the electromagnetic rod 8. At the same time, the control motor 10 rotates to release the pull rope 11 and the metal rod 12. Under the action of gravity, the plastic pipe falls with the pull rope 11. When the lowest plastic pipe descends to the adjacent shelf 14... After the bottom (or already placed plastic pipes) is reached, the industrial vision camera 26 monitors the position of the bottommost plastic pipe. Then, the electromagnetic rod 8 is no longer powered, causing it to lose its magnetism and stop attracting the metal rod 12. Under the influence of gravity, the plastic pipe between the pull rope 1 7 and pull rope 2 11 will roll down and be laid at the bottom of the shelf 14 (or the already placed plastic pipes). The plastic pipes will force the metal rod 12 away from the electromagnetic rod 8. Then, the motor 1 6 is controlled to rotate and rewind the pull rope 1 7 and the electromagnetic rod 8 to their original positions. At the same time, the motor 2 10 is controlled to rotate and rewind the pull rope 2 11 and the metal rod 12 back to their original positions. At this time, the metal rod 12 naturally hangs down and contacts the electromagnetic rod 8. Then, the electromagnetic rod 8 is powered again, causing it to generate a suction force and firmly attract the metal rod 12. Through the above laying method, the plastic pipes only fall from the height of the bottom of the shelf 14 (or the already placed plastic pipes), avoiding the plastic pipes falling from a higher position and reducing the risk of damage to the plastic pipes.

[0030] The U-shaped lifting plate 5 can be made wide, so that multiple plastic pipes can be lifted upward at once. After the plastic pipes are lifted past the highest point of the chain conveyor 4, each plastic pipe rolls down simultaneously between the guide surface 101 and the mounting plate 9. There is a possibility that some plastic pipes will roll directly over the mounting plate 9 and fall out. Therefore, a limiting plate 13 is welded to the front side of each mounting plate 9. The limiting plate 13 and the guide surface 101 are arranged in a trumpet shape, and the limiting plate 13 guides the plastic pipes to roll down between the guide surface 101 and the mounting plate 9.

[0031] After the electromagnetic rod 8 separates from the metal rod 12, all the plastic pipes between the pull rope 7 and pull rope 11 roll down together. The uppermost plastic pipe falls from a greater height, posing a risk of damage. Therefore, a connecting rod 21 is installed on the electromagnetic rod 8, and a baffle 22 is installed on the connecting rod 21 to restrict the position of the metal rod 12. When the electromagnetic rod 8 separates from the metal rod 12, the rolling plastic pipes force the metal rod 12 to slide away from the electromagnetic rod 8 on the connecting rod 21. However, the metal rod 12 can only move as far as it can reach contact with the baffle 22. At this point, the gap between the electromagnetic rod 8 and the metal rod 12 is only wide enough for one plastic pipe to pass through. Then, the motor 6 is controlled to rotate to rewind pull rope 7 and the electromagnetic rod 8 back to their original positions, and the motor 10 is controlled to rotate to rewind pull rope 11 and the metal rod 12 back to their original positions. This allows the plastic pipes to lose the restriction of pull rope 7 and pull rope 11 from bottom to top. This causes the plastic pipes to roll down one by one, preventing all the plastic pipes between pull rope 1 7 and pull rope 2 11 from rolling down together after the electromagnetic rod 8 separates from the metal rod 12, thus avoiding the risk of damage to the uppermost plastic pipe due to its high descent height. Since the through hole of the metal rod 12 is larger than the diameter of the connecting rod 21, there will be no strong friction between the connecting rod 21 and the metal rod 12 during the process of the electromagnetic rod 8 and the metal rod 12 returning to contact each other, thus preventing the metal rod 12 from sliding back to its original position. In addition, the distance between the baffle 22 and the electromagnetic rod 8 can be adjusted to achieve the effect of adjusting the spacing between the electromagnetic rod 8 and the metal rod 12, thereby accommodating plastic pipes of different diameters. During adjustment: first, remove the pin 23 from the connecting rod 21 and the baffle 22, then move the baffle 22, and then insert the pin 23 back into the connecting rod 21 and the baffle 22 to fix the baffle 22 to the connecting rod 21.

[0032] Plastic pipes are prone to deformation under long-term uneven stress. Neat arrangement, especially layered placement, can prevent permanent deformation due to bending stress. To automatically arrange the plastic pipes in an orderly manner (all plastic pipes within the same layer should maintain parallel axes and be closely packed together, with upper-layer pipes placed between adjacent lower-layer pipes), after the electromagnetic rod 8 separates from the metal rod 12, the bottommost plastic pipe contacts the bottom of the shelf 14 (or the already placed plastic pipes). Figure 5As shown; then control the electric push rod 24 to drive the electric clamp 25 to move backward, so that the electric clamp 25 moves to the clamping plate located on both sides of the pull rope 7 and the pull rope 11. Then control the electric clamp 25 to clamp the pull rope 7 and the pull rope 11. Then continue to control the electric push rod 24 to drive the electric clamp 25 to move backward, so that the plastic pipes roll down to the bottom of the shelf 14 (or the plastic pipes that have been placed) in an orderly manner from front to back, thus automatically arranging them in an orderly manner (all pipes in the same layer should keep their axes parallel and the pipes should be close together, with the upper pipes placed between two adjacent pipes on the lower layer).

[0033] Example 2: Based on Example 1, such as Figures 1-5 As shown, it also includes an electric push rod 31 and a push plate 32; an electric push rod 31 is fixedly connected to each mounting plate 9; a push plate 32 is fixedly connected to the telescopic end of each electric push rod 31, and the push plate 32 is used to align the left and right sides of the plastic pipe.

[0034] To prevent damage to the plastic pipe, sponge pads are provided on both sides of the two push plates 32 facing each other.

[0035] After the plastic pipes between the guide surface 101 and the mounting plate 9 are filled, the two electric push rods 31 are controlled to drive the two push plates 32 to move towards each other until the push plates 32 contact the plastic pipes. The two push plates 32 align the left and right sides of each plastic pipe. Then the plastic pipes are stacked on the shelf 14. This makes the left and right sides of each plastic pipe aligned after they are stacked on the shelf 14, so that the plastic pipes are arranged more neatly.
