Description

Technical Field

[0001] This utility model relates to the field of material guiding device technology, and in particular to a material guiding structure for the production of buried PVC-C power cable sheathing pipes. Background Technology

[0002] Cable sheathing is a protective conduit with a certain mechanical strength, laid on the outer layer of cables to prevent damage. Cable protection conduits are mainly installed at intersections where communication cables and power lines cross, preventing short circuits caused by power line breaks that could energize communication cables and steel ropes. This protects cables, switches, circuit boards, and even the entire device from burnout, and also provides some isolation against magnetic field interference from power lines. With the rapid development of underground power cable laying projects, higher requirements have been placed on cable sheathing, leading to the development of PVC-C power sheathing conduits. PVC-C power sheathing conduits are modified PVC pipes with special properties, including good flexibility, high temperature resistance, long service life, and ease of use, and are widely used in domestic power systems.

[0003] In the production process of PVC-C power cable sheathing pipes, since the initial extruded PVC-C power cable sheathing pipes are relatively long, they need to be cut twice to reduce their length. However, at present, there is a lack of corresponding material guiding mechanisms during the cutting process. Generally, the PVC-C power cable sheathing pipes are placed on the operating table manually before cutting. However, manual operation is inefficient and labor-intensive. In view of this, this application proposes a material guiding structure for the production of buried PVC-C power cable sheathing pipes. Utility Model Content

[0004] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides a material guiding structure for the production of buried PVC-C power cable sheathing pipes. The technical solution it solves is as follows: it includes a material guiding hopper, characterized in that the material guiding hopper is arranged obliquely with the left side higher than the right side. A short flat chamber is integrally arranged at the lower right end of the material guiding hopper. A material guiding slope is integrally arranged obliquely to the lower right at the right end of the short flat chamber. An operating platform is integrally arranged at the right end of the material guiding slope. An arc-shaped groove is arranged on the operating platform. Two through grooves are opened at the lower end of the short flat chamber, arranged in a front-to-back correspondence. A lifting device is arranged below the short flat chamber. The lifting device is connected to a U-shaped bracket. The U-shaped bracket is fixedly connected to two top blocks that are inserted into the through grooves one by one. The upper end of each top block has a slope structure with the left side higher than the right side.

[0005] The lifting device includes a frame located below the short flat compartment. A stepper motor is fixedly connected to the upper end of the frame. One end of a drive rod is fixedly connected to the output shaft of the stepper motor. The other end of the drive rod is fixedly connected to an insert rod. A guide cylinder is arranged below the U-shaped support frame. A top rod is slidably connected to the guide cylinder on the same axis. The upper end of the top rod is fixedly connected to the middle of the U-shaped support frame. The guide cylinder has a guide groove arranged vertically. A guide block is fixedly connected to the top rod and slidably connected vertically to the guide groove. A driven ring is fixedly connected to the guide block. The driven ring is movably inserted into the insert rod.

[0006] Preferably, a chip removal groove is provided in the middle of the arc-shaped groove.

[0007] Preferably, the lower end of the feed hopper is fixedly connected to four support legs arranged in a rectangular array.

[0008] Preferably, the lower end of the push rod is coaxially fixedly connected to the upper end of the assist spring, and the lower end of the assist spring is fixedly connected to the inner bottom surface of the guide cylinder.

[0009] Preferably, a grounding flange is coaxially fixedly connected to the lower end of the guide cylinder.

[0010] The beneficial effects of this utility model are:

[0011] During use, the feed hopper and short flat bin of this application facilitate the centralized arrangement of pipes. Under the weight of the pipes themselves, when the rightmost pipe is conveyed into the arc-shaped groove for cutting, the remaining pipes can automatically shift and fill the gap under their own weight, thus facilitating the next conveying of the pipes and completing the feeding work for the cutting operation. This application has a simple structure, is easy to use, and is highly practical. It frees up manual operation and improves work efficiency. Attached Figure Description

[0020] The following is combined with Figure 1-6 The specific embodiments of this utility model will be described in further detail.

[0021] In the first embodiment, the technical solution is that, during use, the guide hopper 1 and the short flat bin 2 facilitate the centralized arrangement of pipes. Under the weight of the pipes, when the rightmost pipe is conveyed into the arc-shaped groove 5 for cutting, the remaining pipes can automatically shift and fill the gap under their own weight, thus facilitating the next conveying of the pipes and completing the material guiding work for the cutting operation. The present application has a simple structure, is easy to use, and is highly practical. It liberates manual operation and improves work efficiency.

[0022] In Example 2, based on Example 1, specifically, when using this application, a corresponding cutting device should be arranged on the right end of the operating table 4 to facilitate cutting operations. This application will not describe the cutting device in detail. The chip removal trough 21 can be used in conjunction with the cutting blade of the cutting device. The left end of the guide hopper 1 can correspond to the connection end of the conveyor belt for conveying PVC-C power cable sheathing pipes, allowing the sheathing pipes to be directly conveyed to the guide hopper 1. When an appropriate number of sheathing pipes enter the guide hopper 1, the conveyor belt stops conveying. In use, the supporting legs 22 provide support for the guide hopper 1, and the frame 11 provides support for the stepper motor 12. Both the supporting legs 22 and the frame 11 can be fixed to the workshop floor by cement pouring. The guide cylinder 16 can be fixed to the ground by the grounding flange 24 and expansion bolts.

[0023] Because the guide hopper 1 is arranged at an angle with the left side higher than the right side, the sheath tube in the guide hopper 1 will, under its own weight, be as shown in the attached diagram of the instruction manual. Figure 1The sheath tubes are arranged adjacent to each other, and the rightmost sheath tube (for ease of description, this sheath tube is referred to as sheath tube 1, 25, and the sheath tube adjacent to sheath tube 1, 25 is referred to as sheath tube 2, 26) will abut against the right end of the short flat compartment 2. At this time, the through groove 6 and the top block 9 in the through groove 6 correspond exactly to the lower edge of sheath tube 1, 25. First, start the lifting device 7 once. Each time the lifting device 7 works, the stepper motor 12 rotates one revolution. Then, the output shaft 13 of the stepper motor 12 will drive the drive rod 14 to rotate. The rotation of the drive rod 14 will rotate along with the insertion rod 15. The insertion rod 15 is movably inserted into the driven ring 20. Then, the insertion rod 15, which rotates with the drive rod 14, will act on the driven ring 20, thereby causing the driven ring 20 and the guide block 19 to move vertically back and forth along the guide groove 18.

[0024] As the guide block 19 moves upward along the vertical groove, the top rod 17, which is fixedly connected to the guide block 19, will also move upward along the guide cylinder 16. The upward movement of the top rod 17 will drive the U-shaped bracket 8 to move upward, and the top block 9, which is fixedly connected to the U-shaped bracket 8, will move downward along the through groove 6. The upward movement of the top block 9 will lift the No. 1 sheath tube 25 upward. Since the upper end of the top block 9 has a slope structure 10 that is higher on the left and lower on the right, when the top block 9 lifts the No. 1 sheath tube 25 to a certain height, the No. 1 sheath tube 25 will slide down along the slope structure 10 on the top block 9 to the guide slope 3. Then the No. 1 sheath tube 25 will enter the arc groove 5 on the operating table 4 along the guide slope 3, which will facilitate the cutting operation of the No. 1 sheath tube 25 by the cutting device.

[0025] After the top block 9 feeds the No. 1 sheath tube 25 into the arc-shaped groove 5, as the stepper motor 12 continues to rotate, the drive rod 14, in conjunction with the insertion rod 15, drives the driven ring 20 downward. Consequently, the guide block 19 moves downward along the guide groove 18 to reset. During the upward resetting process of the guide block 19 along the vertical groove, the corresponding top rod 17, U-shaped bracket 8, and top block 9 also move downward synchronously to reset. After the top rod 17 resets, under the weight of the numerous sheath tubes, the No. 2 sheath tube 26 will automatically move to the right to compensate for the previous position of the No. 1 sheath tube 25, thus facilitating the next material guiding operation. The provided assist spring 23 can extend and retract with the lifting and lowering of the top rod 17, providing assistance for the resetting of the top rod 17.

[0026] Furthermore, during use, the top block 9 should have a certain height so that during its vertical reciprocating movement along the through groove 6, the left end of the top block 9 will always abut against the left side of the second sheath tube 26, preventing the second sheath tube 26 from prematurely moving to the right to compensate for the position of the first sheath tube 25, thereby interfering with the reset of the top block 9. After the cutting and unloading of the first sheath tube 25 is completed, the lifting device 7 is activated again to transport the second sheath tube 26 into the arc-shaped groove 5 for cutting.
