Description

Technical Field

[0002] Polyethylene pipe is also called PE pipe. In China's municipal pipe market, plastic pipes are developing steadily. PE pipe, PP-R pipe and UPVC pipe all have a place. Among them, the strong development momentum of PE pipe is the most remarkable. PE pipe has a wide range of uses, among which water pipes and gas pipes are its two largest application markets.

[0003] During the current production of polyethylene pipes, a conveying device is usually required to convey the pipe extruded by the extruder in a stable and uniform manner away from the extruder to ensure that the extruder can stably produce polyethylene pipes. However, since the newly produced polyethylene pipe has not been completely cooled and formed, it may cause slight deformation of the polyethylene pipe when it is conveyed at the beginning, affecting the subsequent use of the entire polyethylene pipe. In addition, the current conveying device is often only suitable for conveying polyethylene pipes of fixed diameters, and cannot convey polyethylene pipes of different diameters, thereby reducing the scope of application of the entire conveying device. At the same time, the current conveying device often has a single function and is only capable of conveying polyethylene pipes, but cannot wrap a plastic protective film around the outside of the produced polyethylene pipe, and thus cannot protect the surface of the finished polyethylene pipe.

[0014] Preferably, a method for using a conveying device for producing polyethylene pipes comprises the following steps:

[0015] 1. After the extruder extrude the polyethylene pipe, the head end of the polyethylene pipe passes through the two sets of first guide wheels, the inside of the main box and the two sets of second guide wheels in sequence, and then the electric lifting rod is controlled to extend, so that the top set of first guide wheels and the bottom first guide wheels clamp the polyethylene pipe, and then the driving motor is controlled to drive the bottom set of first guide wheels to rotate at a constant speed, so that the polyethylene pipe just extruded moves steadily and evenly to the inside of the main box;

[0016] Second, the electric push rod is controlled to extend, pushing the moving ring to move toward the two ends of the main box. The inner wall of the moving ring squeezes the universal ball to force the U-shaped movable frame to go deeper into the rotating cylinder until the four sets of guide rollers inside the rotating cylinder are against the outside of the polyethylene pipe.

[0017] 3. Then open the warehouse door, fix the head end of the plastic protective film on a set of unloading rollers on the outside of the polyethylene pipe, and then control the driving device to drive the rotating rod to rotate, so that the guide roller rolls on the outside of the polyethylene pipe. At the same time, the plastic protective film on the unloading roller is gradually wrapped around the outside of the polyethylene pipe.

[0018] Compared with the prior art, the present invention provides a conveying device for polyethylene pipe production and a method of using the same, which has the following beneficial effects:

[0019] 1. When the polyethylene pipe is transported, the present invention controls the driving device to drive the rotating rod to rotate, and the rotating rod drives the mounting ring and the rotating drum to rotate through the transmission of the gear and the annular rack, and the four groups of guide rollers on the rotating drum are always against the outside of the polyethylene pipe. When the rotating drum rotates, it will drive the guide rollers thereon to roll on the outside of the polyethylene pipe. Since there are always four groups of guide rollers against the outside of the polyethylene pipe, the polyethylene pipe is limited to prevent the polyethylene pipe from sagging, and when the guide rollers roll on the outside of the polyethylene pipe, the outside of the polyethylene pipe is also smoothed, further improving the smoothness of the outside of the polyethylene pipe.

[0020] 2. When the present invention needs to transport polyethylene pipes of different diameters, if the diameter of the polyethylene pipe becomes smaller, the electric push rod is controlled to extend, and the moving ring inside the main box is pushed to move toward the two ends of the main box through the connecting block. Since the inner side of the moving ring is funnel-shaped, the inner wall of the moving ring squeezes the universal ball and forces the U-shaped movable frame to penetrate into the rotating cylinder. At this time, the distance between the four groups of guide rollers inside the rotating cylinder is shortened, so that the four groups of guide rollers can abut against the outside of the polyethylene pipe with a smaller diameter. On the contrary, if the polyethylene pipe increases, the electric push rod is controlled to shorten, and the two groups of moving rings inside the main box approach each other. The elastic potential energy of the first spring forces the four groups of moving rings to gradually approach the inner wall of the rotating cylinder, thereby increasing the distance between the four groups of moving rings, so that the moving rings can abut against the outside of the polyethylene pipe with a larger diameter, thereby improving the application range of the entire conveying device.

[0021] 3. Before conveying the polyethylene pipe, the present invention fixes the head end of the plastic protective film on a set of unwinding rollers on the outside of the polyethylene pipe, and then controls the driving device to drive the rotating rod to rotate. During the rotation of the mounting ring, the plastic protective film is gradually and automatically wrapped around the outside of the polyethylene pipe to protect the polyethylene pipe, thereby preventing the polyethylene pipe from being scratched or notched due to accidental collision during transportation, which affects the subsequent use of the polyethylene pipe. After the plastic protective film is wrapped around the outside of the polyethylene pipe, the four sets of guide rollers inside the second set of rotating drums rotate around the polyethylene pipe, so that the plastic protective film can wrap the polyethylene pipe more tightly.

[0043] Furthermore, a method for using a conveying device for producing polyethylene pipes is provided, and the steps of the method for using the conveying device are as follows:

[0044] 1. After the extruder extrude the polyethylene pipe, the head end of the polyethylene pipe passes through the two sets of first guide wheels, the inside of the main box 1 and the two sets of second guide wheels in sequence, and then the electric lifting rod is controlled to extend, so that the top set of first guide wheels and the bottom first guide wheels clamp the polyethylene pipe, and then the driving motor is controlled to drive the bottom set of first guide wheels to rotate at a constant speed, so that the polyethylene pipe just extruded moves steadily and evenly to the inside of the main box 1;

[0045] Second, the electric push rod 602 is controlled to extend, pushing the moving ring 604 to move toward the two ends of the main box 1, and the inner wall of the moving ring 604 squeezes the universal ball 607 to force the U-shaped movable frame 608 to go deeper into the rotating cylinder 12 until the four sets of guide rollers 605 inside the rotating cylinder 12 abut against the outside of the polyethylene pipe;

[0046] 3. Then open the warehouse door 8, fix the head end of the plastic protective film on a set of discharge rollers 702 to the outside of the polyethylene pipe, then control the driving device 2 to drive the rotating rod 17 to rotate, so that the guide roller 605 rolls on the outside of the polyethylene pipe. At the same time, the plastic protective film on the discharge roller 702 is gradually wrapped around the outside of the polyethylene pipe.

[0047] Embodiment 1, as Figure 1-3 As shown, after the extruder extrude the polyethylene pipe, the head end of the polyethylene pipe passes through between the two groups of first guide wheels, inside the main box 1 and between the two groups of second guide wheels in sequence, and then the control panel 4 controls the electric lifting rod to extend, so that the top group of first guide wheels and the bottom first guide wheels clamp the polyethylene pipe, and then the drive motor is controlled to drive the bottom group of first guide wheels to rotate at a uniform speed, so that the polyethylene pipe just extruded moves stably and evenly to the inside of the main box 1.

[0048] Embodiment 2, as Figure 2 , Figure 5-6 and Fig. 9As shown, the angle between the central axis of the guide roller 605 and the central axis of the polyethylene pipe is 5°, that is, the surface of the guide roller 605 is not completely in contact with the surface of the polyethylene pipe, and the two ends of the outer side of the guide roller 605 are not in contact with the surface of the polyethylene pipe. In this way, when the guide roller 605 rolls on the surface of the polyethylene pipe, the friction force will not affect the movement of the polyethylene pipe in the direction of the second guide device 3.

[0049] Embodiment 3, as Figure 2 and Figure 8-10 As shown, when it is necessary to take out the discharge roller 702 from the inside of the main box 1, first open the warehouse door 8, then drive the rotating rod 17 to rotate through the driving device 2, and the rotating rod 17 will also drive the mounting ring 11 to rotate through the annular rack 14 and the gear 16, and the discharge roller 702 will also rotate accordingly. When a group of discharge rollers 702 rotate to the position of the warehouse door 8, the driving device 2 is controlled to stop rotating. Then the operator holds the discharge roller 702 with one hand and pushes the push rod 704 toward one end of the insertion shaft 701 with the other hand, and pushes the push rod 704 into the inside of the card slot 703, and the second spring 709 is shortened by force and stores elastic potential energy. At this time, one end of the movable rod 705 completely leaves the inner side of the adjacent group of second bearings 707. Then, the unloading roller 702 is moved to the end away from the unloading roller 702, so that the plug-in shaft 701 leaves the corresponding second bearing 707. In this way, the unloading roller 702 can be taken out from the inside of the main box 1. After that, a new group of plastic protective film rolls are put on the outside of the group of unloading rollers 702, and then the plug-in shafts 701 and the movable rod 705 at both ends of the unloading roller 702 are re-inserted into the corresponding second bearing 707, thereby completing the replacement of the plastic protective film roll.

[0050] Working principle: Connect the device to the power supply before use. When it is necessary to transport polyethylene pipes of different diameters, if the diameter of the polyethylene pipe becomes smaller, the electric push rod 602 is controlled to extend, and the moving ring 604 inside the main box 1 is pushed to move toward the two ends of the main box 1 through the connecting block 603. Since the inner side of the moving ring 604 is funnel-shaped, the inner wall of the moving ring 604 squeezes the universal ball 607 to force the U-shaped movable frame 608 to go deeper into the rotating cylinder 12. At this time, the spacing between the four groups of guide rollers 605 inside the rotating cylinder 12 is shortened, so that the four groups of guide rollers 605 can be against the outside of the polyethylene pipe with a smaller diameter. On the contrary, if the polyethylene pipe increases, the electric push rod 602 is controlled to shorten, and the two groups of moving rings 604 inside the main box 1 are close to each other. The elastic potential energy of the first spring 609 forces the four groups of moving rings 604 to gradually approach the inner wall of the rotating cylinder 12, thereby increasing the four groups The spacing between the moving rings 604 allows the moving rings 604 to rest against the outside of the polyethylene pipe with a larger diameter. When the polyethylene pipe is transported, the control driving device 2 drives the rotating rod 17 to rotate, and the rotating rod 17 drives the mounting ring 11 and the rotating cylinder 12 to rotate through the transmission of the gear 16 and the annular rack 14, and the four groups of guide rollers 605 on the rotating cylinder 12 always rest against the outside of the polyethylene pipe. When the rotating cylinder 12 rotates, it will drive the guide rollers 605 thereon to roll on the outside of the polyethylene pipe. At this time, the universal ball 607 on the mounting seat 606 rolls on the inner wall of the moving ring 604. At the same time, when the mounting ring 11 rotates, it will also drive the four groups of discharge rollers 702 to rotate around the central axis of the main box 1. During this process, the plastic protective film on one group of discharge rollers 702 is gradually wrapped around the outside of the polyethylene pipe, and the polyethylene pipe wrapped by the plastic protective film leaves the inside of the main box 1.
