Description

Technical Field

[0001] This utility model relates to the field of plastic pipe cutting, and in particular to a large plastic pipe cutting device. Background Technology

[0002] Plastic pipes are widely used in municipal, water conservancy, and power engineering projects due to their advantages such as light weight, corrosion resistance, and easy installation. With the development of engineering needs, the use of large-diameter plastic pipes is increasing, and cutting operations are becoming more frequent. Traditional cutting methods mainly rely on manual labor or hand tools, which easily leads to uneven cuts, burrs, and low efficiency. This is especially true for large-diameter, thick-walled plastic pipes, where operation is more difficult, time-consuming, labor-intensive, and poses certain safety hazards. Furthermore, existing tools have poor versatility and are difficult to adapt to the cutting needs of different pipe specifications. Therefore, a large-scale plastic pipe cutting device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0021] like Figure 1-6 As shown, a large plastic pipe cutting device includes a support base 1. In this embodiment, the support base 1 includes a base plate and an H-shaped support frame disposed on the base plate. An inclined support is disposed between the H-shaped support frame and the base plate. An outer ring 2 is disposed on the top of the support base 1. A cutting rotating ring 3 is rotatably disposed in the outer ring 2. A bearing is disposed between the outer ring 2 and the cutting rotating ring 3. A rotary drive mechanism 4 for driving the cutting rotating ring 3 to rotate is disposed on the support base 1. One or more cutting mechanisms 5 are retractably disposed on the front side of the cutting rotating ring 3. In this embodiment, the number of cutting mechanisms 5 is three and they are evenly distributed. A telescopic control mechanism 6 for controlling the telescopic movement of the cutting mechanisms 5 is also disposed in the cutting rotating ring 3.

[0022] With this design, the pipe body 7 can be coaxially inserted into the cutting rotating ring 3, and the cutting mechanism 5 can be moved to the cutting position by the telescopic control mechanism 6. Then, the cutting rotating ring 3 is driven by the rotation drive mechanism 4 to drive the cutting mechanism 5 to rotate synchronously, thereby completing the cutting of the pipe body 7. This realizes the automated cutting of large plastic pipes and can adapt to plastic pipes of different diameters. It should be noted that the pipe body 7 is clamped and fixed by the existing fixing device during this process, so it will not be described in detail here.

[0023] In the preferred embodiment, the front side of the cutting rotating ring 3 is provided with a telescopic groove 302 for movably mounting the cutting mechanism 5, and limit blocks 303 are provided on the two inner wall surfaces opposite to each other of the telescopic groove 302.

[0024] Furthermore, the cutting mechanism 5 includes a telescopic seat 501 movably installed in the telescopic groove 302. Both sides of the telescopic seat 501 are provided with limiting grooves 502 that slide with the limiting block 303. A support frame 503 is provided at the front edge of the bottom of the telescopic seat 501. A cutting machine 504 is installed on the support frame 503. The cutting machine 504 is a common commercially available product, so it will not be described in detail here.

[0025] With this design, the cutting position of the cutting machine 504 can be adjusted by extending and retracting the telescopic seat 501 in the telescopic groove 302.

[0026] In the preferred embodiment, the cutting mechanism 5 also includes a telescopic cutting auxiliary wheel 505.

[0027] Furthermore, the cutting mechanism 5 includes a telescopic cavity 5050 disposed in the telescopic seat 501 and having an open bottom. Sliding grooves 5051 are symmetrically arranged on the two inner walls of the telescopic cavity 5050. A telescopic rod 5053 with its bottom end protruding from the opening is movably installed in the telescopic cavity 5050. A sliding block 5054 is provided at one end of the telescopic rod 5053 located in the telescopic cavity 5050, which slides in cooperation with the sliding groove 5051, thereby limiting its telescopic range. An auxiliary wheel 5055 that can roll in the direction of rotation is provided at the protruding end. Through the rolling contact between the auxiliary wheel 5055 and the tube body 7, auxiliary clamping can be achieved during the rotational cutting process, improving the stability of the cutting. A telescopic spring 5052 that abuts against the telescopic rod 5053 is also provided in the telescopic cavity 5050.

[0028] With this design, after the cutting machine 504 penetrates into the tube body 7, the auxiliary wheel 5055 compresses the telescopic spring 5052 to abut against the outer wall of the tube body 7, thereby assisting in cutting while avoiding affecting the normal operation of the cutting machine 504.

[0029] In the preferred embodiment, the telescopic control mechanism 6 includes a rotating cavity 601 disposed in the cutting rotating ring 3. The rotating cavity 601 is connected to the telescopic groove 302. A guide disk 602 is rotatably disposed in the rotating cavity 601. The guide disk 602 is rotatably mounted in the rotating cavity 601 through a bearing disposed on its inner ring wall. A telescopic guide groove 603 corresponding to the cutting mechanism 5 is disposed on the side of the guide disk 602 near the telescopic groove 302. A guide seat 506 that slides with the telescopic guide groove 603 is disposed on the back of the telescopic seat 501. A guide drive mechanism for driving the guide disk 602 to rotate is disposed outside the cutting rotating ring 3.

[0030] With this design, the cutting mechanism 5 can be controlled to extend and retract in the telescopic groove 302 by rotating the drive guide plate 602 and by sliding the telescopic guide groove 603 with the guide seat 506.

[0031] Furthermore, the guide drive mechanism includes a first toothed ring 604 disposed on the outer ring of the guide disk 602, a notch 607 corresponding to the first toothed ring 604 disposed on the outer wall of the cutting rotating ring 3, a first drive device 605 mounted on the outside of the cutting rotating ring 3, and a first drive gear 606 disposed on the output shaft of the first drive device 605, which passes through the notch 607 and meshes with the first toothed ring 604.

[0032] With this design, the guide disc 602 can be rotated by the drive of the first drive device 605 and the meshing relationship between the first drive gear 606 and the first gear ring 604, thereby achieving the above-mentioned effect of adjusting the extension and retraction of the cutting mechanism 5.

[0033] In the preferred embodiment, a second toothed ring 301 is provided on the other side of the cutting rotating ring 3, and the rotating drive mechanism 4 includes a second drive device 401 provided on the crossbeam of the support base 1. A second drive gear 402 that meshes with the second toothed ring 301 is provided on the output shaft of the second drive device 401, so that the cutting rotating ring 3 can be driven to rotate as a whole by the drive of the second drive device 401.

[0034] It should be noted that in this embodiment, both the first driving device 605 and the second driving device 401 are composed of a motor and a reducer transmission combination.

[0035] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
