Description

Technical Field

[0001] The utility model relates to the technical field of MPP pipe processing, in particular to MPP pipe cutting processing equipment. Background Art

[0002] With the acceleration of urbanization, the demand for underground pipelines is growing. MPP (modified polypropylene) pipes, due to their excellent corrosion resistance, compressive strength, and long service life, are widely used in applications such as power cable protection conduits. However, in actual construction, to ensure the sealing of pipeline joints and the overall aesthetics, MPP pipes must be precisely cut and polished, which is an indispensable step in ensuring project quality.

[0003] While some existing highly automated MPP pipe cutting equipment has been able to effectively address the issue of rapid cutting, deficiencies remain in the subsequent polishing process. Specifically, before polishing the cut, the relative position between the polishing wheel and the pipe must be adjusted according to the pipe diameter to ensure good contact and achieve the desired polishing effect. However, most current equipment on the market can only adjust the height of each polishing wheel individually, failing to achieve simultaneous raising and lowering of both wheels. This design requires the operator to set the height of each polishing wheel separately, increasing the difficulty and time required for adjustment. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an MPP pipe cutting processing equipment, which has a simple structure and can adjust the height of the polishing wheels on both sides at the same time, thereby improving convenience.

[0005] The MPP pipe cutting processing equipment of the utility model includes a base plate, two sliders are slidably connected to the top of the base plate, each slider is provided with a height adjustment mechanism, the output end of the height adjustment mechanism is a lifting plate, and a polishing mechanism is installed on the top of the lifting plate. The height adjustment mechanism includes a screw rod rotatably connected to the slider, each screw rod end is rotatably connected to one end of a connecting rod, and the other ends of the two connecting rods are rotatably connected through an intermediate shaft, and the two screw rods are both transmission connected to the intermediate shaft.

[0006] As a preferred solution of the present invention, a sprocket 1 is installed at one end of the screw rod, two sprockets 2 are installed on the intermediate shaft, and chains are sleeved on the sprockets 1 and 2.

[0007] As a preferred solution of the present invention, it also includes a power mechanism for driving the screw to rotate.

[0008] As a preferred solution of the present invention, the power mechanism is a servo motor fixed to one end of one of the screw rods.

[0009] As a preferred solution of the present invention, the height adjustment mechanism further comprises two movable plates sliding on the slider, both movable plates are rotatably connected to one end of a driving rod, and the other end of the driving rod is rotatably connected to the lifting plate;

[0010] The lead screw has a forward thread and a reverse thread, and the forward thread and the reverse thread are respectively threadably connected to the two moving plates.

[0011] As a preferred solution of the present invention, the polishing mechanism includes a second servo motor fixedly connected to the lifting plate, and the output end of the second servo motor is a polishing wheel.

[0012] As a preferred solution of the present invention, two linear mechanisms 1 are fixed on the top of the base plate, and the output end of the linear mechanism 1 is connected to the slider.

[0013] As a preferred solution of the present invention, a base plate is fixed at the middle position of the top of the bottom plate, and the base plate is rotatably connected to two support shafts.

[0014] As a preferred solution of the present invention, a second linear mechanism is fixed above the base plate, and the output ends of the second linear mechanism are two self-rotating limit shafts.

[0015] As a preferred solution of the present invention, at least two driving rods are rotatably mounted on each movable plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: when in use, the positions of the two sliders are adjusted according to the length of the pipe to be processed so that they are at an appropriate distance so that the polishing mechanism can polish the incision. During this process, the distance between the two sliders will change. In order to adapt to this change, the angle between the two connecting rods changes. During this process, the distance between the screw rod and the intermediate shaft will not change, so that the chain can operate normally, and sprocket one and sprocket two are of the same model. When the two sliders move, the screw rod will not rotate. After the position of the slider is adjusted, one of the screw rods is rotated, and with the cooperation of sprocket one, sprocket two, chain and intermediate shaft, the other screw rod is driven to rotate synchronously, thereby driving the two height adjustment mechanisms to act synchronously, so that the height of the two polishing mechanisms can be adjusted at the same time, which greatly reduces the time required to manually adjust the height of each side separately, thereby improving the overall work efficiency.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "embodiment" as used herein refers to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0024] Example

[0025] Reference Figure 1-Figure 3 This embodiment provides an MPP pipe cutting processing equipment, including a base plate 1, two sliders 2 are slidably connected to the top of the base plate 1, the sliders 2 are slidably installed on a track 20 fixed to the top of the base plate 1, and the track 20 is arranged along the axial direction of the MMP pipe. Each slider 2 is provided with a height adjustment mechanism, the output end of the height adjustment mechanism is a lifting plate 3, and a polishing mechanism is installed on the top of the lifting plate 3. The height adjustment mechanism includes a screw rod 4 rotatably connected to the slider 2, and each end of the screw rod 4 is rotatably connected to one end of a connecting rod 5. The other ends of the two connecting rods 5 are rotatably connected through an intermediate shaft 6, and the intermediate shaft 6 is lower than the two screw rods 4. The two connecting rods 5 form a V shape, and the two screw rods 4 are both transmission-connected to the intermediate shaft 6; more specifically, a sprocket 7 is installed at one end of the screw rod 4, and two sprockets 8 are installed on the intermediate shaft 6. Chains 9 are set on the sprocket 7 and the sprocket 8, and the sprocket 7 and the sprocket 8 are of the same model;

[0026] In this embodiment, when in use, the positions of the two sliders 2 are adjusted according to the length of the pipe to be processed so that they are at an appropriate distance so that the polishing mechanism can polish the incision. During this process, the distance between the two sliders 2 will change. In order to adapt to this change, the angle between the two connecting rods 5 changes. During this process, the distance between the screw rod 4 and the intermediate shaft 6 will not change, so that the chain 9 can operate normally, and the sprocket 1 7 and the sprocket 2 8 are of the same model. When the two sliders 2 move, the screw rod 4 will not rotate. After the position of the slider 2 is adjusted, one of the screw rods 4 is rotated, and with the cooperation of the sprocket 1 7, the sprocket 2 8, the chain 9 and the intermediate shaft 6, the other screw rod 4 is driven to rotate synchronously, thereby driving the two height adjustment mechanisms to act synchronously, so that the height of the two polishing mechanisms can be adjusted at the same time, which greatly reduces the time required to manually adjust the height of each side separately, thereby improving the overall work efficiency.

[0027] As a preferred solution of the present invention, it also includes a power mechanism 10 for driving the screw rod 4 to rotate. More specifically, the power mechanism 10 is a servo motor fixed to one end of one of the screw rods 4. Driven by the servo motor, the operator does not need to manually rotate the screw rod 4, which greatly reduces labor intensity. Especially when processing a large number of pipes, it can significantly reduce labor costs.

[0028] As a preferred solution of the present invention, the height adjustment mechanism further includes two movable plates 11 sliding on the slider 2, the movable plates 11 slide on the track 21 fixedly connected to the slider 2, and the two movable plates 11 are both rotatably connected to one end of the drive rod 12, such as Figure 3 As shown, the driving rod 12 is inclined, and the two driving rods 12 are symmetrically arranged, and the other end of the driving rod 12 is rotatably connected to the lifting plate 3; the screw rod 4 has a forward thread and a reverse thread, and the forward thread and the reverse thread are respectively threadedly connected to the two movable plates 11; when in use, the servo motor drives the screw rod 4 to rotate. Since the screw rod 4 has a forward thread and a reverse thread, which are respectively threadedly connected to the two movable plates 11, when the screw rod 4 rotates, the two movable plates 11 will move in opposite directions. As the movable plate 11 moves, one end of the driving rod 12 moves synchronously with the movable plate 11, and the other end pushes the lifting plate 3 up and down, so that the lifting plate 3 can be height-adjusted.

[0029] As a preferred solution of the present invention, the polishing mechanism includes a servo motor 13 fixedly connected to the lifting plate 3, the output end of the servo motor 13 is a polishing wheel 14, and the polishing wheel 14 is driven to rotate by controlling the servo motor 13.

[0030] As a preferred solution of the present invention, two linear mechanisms 15 are fixed on the top of the base plate 1, and the output end of the linear mechanism 15 is connected to the slider 2. The linear mechanism 15 is a cylinder or an electric push rod, and the linear mechanism 15 is used to control the movement of the slider 2 without manual adjustment.

[0031] As a preferred solution of the present invention, a base plate 16 is fixed to the middle position of the top of the base plate 1, and the base plate 16 is rotatably connected to two support shafts 17; a linear mechanism 18 is fixed above the base plate 1, and the linear mechanism 18 is a cylinder or an electric push rod, and the output end of the linear mechanism 18 is two limit shafts 19 that can rotate. Figure 1 As shown, the two support shafts 17 are symmetrically arranged, the two limit shafts 19 are symmetrically arranged, and the support shaft 17 located below is driven to rotate by external power. When in use, the mpp pipe is placed on the two support shafts 17. There is a distance between the two support shafts 17, which can position the pipe. Then, the linear mechanism 18 is operated to make the limit shaft 19 contact with the pipe. Then, the external power is operated to drive the pipe to rotate. Under the action of the support shaft 17 and the limit shaft 19, the pipe is driven to rotate. When the pipe rotates, the polishing wheel 14 polishes the pipe cut.

[0032] As a preferred solution of the present invention, at least two driving rods 12 are rotatably mounted on each movable plate 11 to improve the lifting stability of the lifting plate 3 .

[0033] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.
