Description

Technical Field

[0001] This utility model relates to the field of steel wire mesh polyethylene composite pipe processing, and more specifically, this utility model relates to a device for preparing peeling strips for steel wire mesh polyethylene composite pipe. Background Technology

[0002] Steel wire mesh polyethylene composite pipes are widely used in municipal water supply, gas transmission and other fields because they combine the corrosion resistance of polyethylene and the high strength of steel wire mesh. The interlayer bonding strength is a key indicator to ensure the long-term stable operation of the pipes and needs to be tested by peel test. A qualified peel sample is the basis for the accuracy of the test.

[0003] Traditionally, the preparation of stripping samples often relies on manual labor or simple tools for layering. However, the fixed structure of traditional devices is not adjustable, making it unsuitable for pipes of different lengths and resulting in poor versatility. At the same time, the cutting depth is difficult to control precisely, and it is impossible to achieve coordination between pipe rotation and the axial movement of the cutting device. It is also difficult to cut precisely along the interface between the wire mesh and the polyethylene layer, leading to incomplete or excessive damage to the strip layering, which affects the accuracy of subsequent test data.

[0004] Therefore, it is necessary to redesign a strip preparation device for steel wire mesh polyethylene composite pipe to address the above-mentioned problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for preparing layered strips of steel wire mesh polyethylene composite pipe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for preparing peeling strips of steel wire mesh polyethylene composite pipe includes a mounting base. A groove is formed on the upper surface of the mounting base, and an adjusting device is installed within the groove. A second fixing plate is fixedly connected to the output end of the adjusting device. A first fixing plate is fixedly mounted on the upper surface of the mounting base. Clamping blocks are rotatably connected to one side of both the first and second fixing plates. A fixing frame is fixedly mounted on the upper surface of the first fixing plate, and a driving device is provided on one side of the fixing frame. A cutting device is fixedly connected to the output end of the driving device.

[0008] In a preferred embodiment, the adjusting device includes a threaded rod, which is mounted on the inner wall of the slide groove via a bearing. The threaded rod is threadedly connected to a slider, which is slidably connected within the slide groove. A second fixing plate is fixedly connected to the upper end face of the slider. Elastic protective membranes are fixedly connected to both sides of the slider, and one end of each elastic protective membrane is fixedly connected to the inner wall of the slide groove.

[0009] In a preferred embodiment, the drive device includes a reciprocating screw, which is rotatably mounted on one side of a fixed frame via a bearing. One end of the reciprocating screw rotatably passes through one side of the fixed frame and extends outward to be mounted with a second synchronous pulley. The reciprocating screw is connected to a moving block via a screw sleeve. A hydraulic telescopic cylinder is fixedly connected to the bottom end of the moving block, and the cutting device is fixedly connected to the output shaft of the hydraulic telescopic cylinder. A limit block is fixedly connected to the end of the reciprocating screw away from the second synchronous pulley.

[0010] In a preferred embodiment, a mounting bracket is fixedly mounted on one side of the mounting base, a first motor is fixedly connected to the mounting bracket, and the output shaft of the first motor passes through one side of the first fixed plate and is fixedly connected to a clamping block at a corresponding position. A first synchronous pulley is fixedly connected to the output shaft of the first motor, and a synchronous belt is installed between the first synchronous pulley and the second synchronous pulley.

[0011] In a preferred embodiment, two limiting rods are symmetrically fixedly installed on one side of the fixing frame, and the moving block is slidably sleeved on the outer wall of the two limiting rods.

[0012] In a preferred embodiment, a second motor is fixedly mounted on one side of the mounting base, and the output shaft of the second motor rotates through one side of the mounting base and is fixedly connected to one end of a threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a second motor, an adjustment device and other devices, drives the threaded rod to rotate through the second motor, which can flexibly adjust the distance between the first fixed plate and the second fixed plate, and can adapt to steel wire mesh polyethylene composite pipes of different lengths. At the same time, the elastic protective membranes on both sides of the slider move and expand and contract with the slider, which can effectively block cutting debris from entering the groove and avoid interfering with the operation of the adjustment device.

[0015] 2. This utility model, by setting up a drive device, a first motor and other devices, can accurately adjust the cutting depth of the cutting device with the help of a hydraulic telescopic cylinder. Combined with the rotation of the pipe and the axial reciprocating motion of the cutting device driven by the drive device, it can achieve precise cutting of the interface between the wire mesh and the polyethylene layer.

[0016] In summary, this utility model is simple to operate.

The elastic protective membranes on both sides of the slider can prevent cutting debris from entering the groove and avoid interfering with the operation of the adjustment device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-4 A device for preparing strips of steel wire mesh polyethylene composite pipe includes a mounting base 1. A groove 18 is provided on the upper surface of the mounting base 1. An adjustment device is provided in the groove 18. A second fixing plate 5 is fixedly connected to the output end of the adjustment device. A first fixing plate 2 is fixedly installed on the upper surface of the mounting base 1. Clamping blocks 14 are rotatably connected to one side of the first fixing plate 2 and the second fixing plate 5, respectively. As shown in the attached drawings, each clamping block 14 is conical and double-conical, thus adapting to pipes of different diameters. A fixing frame 6 is fixedly installed on the upper surface of the first fixing plate 2. A driving device is provided on one side of the fixing frame 6. A cutting device 17 is fixedly connected to the output end of the driving device.

[0024] The adjusting device includes a threaded rod 19, which is mounted on the inner wall of the slide groove 18 via bearings. The threaded rod 19 is threadedly connected to a slider 20, which is slidably connected within the slide groove 18. A second fixing plate 5 is fixedly connected to the upper end face of the slider 20. Elastic protective membranes 15 are fixedly connected to both sides of the slider 20, and one end of each elastic protective membrane 15 is fixedly connected to the inner wall of the slide groove 18. The elastic protective membranes 15 on both sides of the slider 20 extend and retract with the movement of the slider 20, which can effectively block cutting debris from entering the slide groove 18, prevent the adjusting device from jamming or wearing, ensure its long-term stable operation, and reduce maintenance costs.

[0025] The drive device includes a reciprocating screw 11, which is rotatably mounted on one side of the fixed frame 6 via a bearing. One end of the reciprocating screw 11 rotatably passes through one side of the fixed frame 6 and extends outward to install a second synchronous pulley 8. The reciprocating screw 11 is connected to a moving block 13 via a screw sleeve. The bottom end of the moving block 13 is fixedly connected to a hydraulic telescopic cylinder 16, and the cutting device 17 is fixedly connected to the output shaft of the hydraulic telescopic cylinder 16. The end of the reciprocating screw 11 away from the second synchronous pulley 8 is fixedly connected to a limit block 10, which can limit the stroke of the moving block 13 and prevent the cutting device 17 from exceeding the range of the reciprocating screw 11.

[0026] A mounting bracket 3 is fixedly installed on one side of the mounting base 1. A first motor 4 is fixedly connected to the mounting bracket 3. The output shaft of the first motor 4 passes through one side of the first fixed plate 2 and is fixedly connected to the corresponding clamping block 14. A first synchronous pulley 7 is fixedly connected to the output shaft of the first motor 4. A synchronous belt 9 is installed between the first synchronous pulley 7 and the second synchronous pulley 8. Both the first synchronous pulley 7 and the second synchronous pulley 8 can drive each other to rotate through the synchronous belt 9.

[0027] Two limiting rods 12 are symmetrically fixedly installed on one side of the fixed frame 6, and the moving block 13 is slidably sleeved on the outer wall of the two limiting rods 12. The limiting rods 12 guide the moving block 13 to ensure its smooth movement and prevent the cutting device 17 from shaking and affecting the cutting accuracy.

[0028] A second motor 21 is fixedly installed on one side of the mounting base 1, and the output shaft of the second motor 21 rotates through one side of the mounting base 1 and is fixedly connected to one end of the threaded rod 19.

[0029] In use, the steel wire mesh polyethylene composite pipe to be processed is placed between the first fixed plate 2 and the second fixed plate 5. The second motor 21 is started, and its output shaft rotates through one side of the mounting base 1 and extends into the slide groove 18, driving the threaded rod 19 to rotate. This causes the threaded slider 20 to slide along the slide groove 18, thereby moving the second fixed plate 5. By adjusting the distance between the first fixed plate 2 and the second fixed plate 5, the clamping blocks 14 on both sides clamp the pipe, ensuring that the pipe will not shake during processing. At the same time, the elastic protective membranes 15 on both sides of the slider 20 extend and retract with the movement of the slider 20, which can prevent cutting debris from entering the slide groove 18 and affecting the operation of the adjustment device.

[0030] The first motor 4 on the mounting frame 3 starts, and its output shaft drives the clamping block 14 on the side of the first fixed plate 2 to rotate. On the other hand, it drives the reciprocating screw 11 on the side of the fixed frame 6 to rotate through the first synchronous pulley 7, the synchronous belt 9 and the second synchronous pulley 8. Since the moving block 13 is slidably sleeved on the two limit rods 12, under the drive of the reciprocating screw 11, the moving block 13 can only make reciprocating linear motion along the axial direction of the reciprocating screw 11. The hydraulic telescopic cylinder 16 and the cutting device 17 fixed at the bottom of the moving block 13 also move accordingly, so that the cutting device 17 can obtain the ability to move along the axial direction of the pipe.

[0031] Once the cutting device 17 moves to the appropriate position, the hydraulic telescopic cylinder 16 is activated, and its output shaft drives the cutting device 17 to descend. The cutting depth is adjusted according to the requirements of pipe layering, so that the cutting device 17 accurately contacts the bonding surface of the steel wire mesh and polyethylene layer of the pipe. At the same time, the pipe rotates under the drive of the clamping block 14. As the cutting device 17 reciprocates with the moving block 13, it cuts the rotating pipe, thereby achieving the layering of the steel wire mesh and polyethylene layer.

[0032] The limiting block 10 at the end of the reciprocating screw 11 away from the second synchronous pulley 8 can limit the maximum travel of the moving block 13, preventing the cutting device 17 from exceeding the pipe range and causing invalid cutting or equipment damage, thus ensuring the safety and stability of the cutting process.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
