[0032] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figure 1 As shown, the embodiment of the utility model application provides a pipe cutting device, including: a box body 1, a cutting mechanism 2, a dust suction mechanism 3, a bearing plate 4 and a telescopic structure 5.

[0035] The cutting mechanism 2 is arranged above the box body 1, and is used to cut the pipe to be cut; the box body 1 is provided with a collecting chamber 11 for receiving the cut pipe; the dust suction mechanism 3 is connected to the collecting chamber 11, and collects and processes the dust generated during the pipe cutting process; the supporting plate 4 is movably arranged in the collecting chamber 11 through the telescopic structure 5, and a plurality of filter holes are opened on the supporting plate 4, and the supporting plate 4 can move downward under the drive of the telescopic structure 5.

[0036] When in use, the plastic tube to be cut is placed or transported to the cutting area on the top of the box 1 (the surface of the box 1 corresponding to the cutting mechanism 2), and the cutting mechanism 2 cuts the plastic tube. The cut plastic tube falls onto the supporting plate 4 in the collecting chamber 11. As the number of plastic tubes on the supporting plate 4 increases, the telescopic structure 5 drives the supporting plate 4 to gradually move downward, and the dust generated during the cutting process is collected and processed by the dust collection mechanism 3.

[0037] As an implementation scenario, in this scenario, the telescopic structure 5 is a plurality of sets of telescopic springs, see the attached Figure 1 As shown, the lower end of the telescopic spring is connected to the bottom of the collecting chamber 11, and the upper end is connected to the bottom of the supporting plate 4. The cut plastic tube falls onto the supporting plate 4. The supporting plate 4 squeezes the telescopic spring under the action of gravity, and the supporting plate 4 moves downward at the same time. This can effectively prevent the plastic tube from falling with too large a height difference, thereby avoiding unnecessary damage.

[0038] Optionally, a telescopic rod is provided between the carrying plate 4 and the inner bottom of the collecting chamber 11, and the telescopic spring is sleeved on the telescopic rod.

[0039] As another implementation scenario, in this scenario, the telescopic structure 5 is an electric telescopic rod (not shown in the figure), which is arranged at the bottom of the collection chamber 11, and its upper end is connected to the carrier plate 4. The cut plastic tube falls onto the carrier plate 4, and the electric telescopic rod moves downward by a unit distance. The cut plastic tube is moved downward by a unit distance along with the electric telescopic rod by the carrier plate 4. Every time the plastic tube falls, the electric telescopic rod moves downward by a unit distance. The movement mode of the electric telescopic rod can be set by the control system, that is, the input end of the electric telescopic rod is electrically connected to the output end of the controller. The electric telescopic rod drives the carrier plate 4 to move gradually downward, which can effectively prevent the cut plastic tube from falling with too large a height difference.

[0042] The top plate 22 is installed on the box body 1 through the vertical rod 21, and the cylinder 23 is installed on the top plate 22. The movable end of the cylinder 23 is connected to the connecting plate 24 below the top plate 22. The connecting plate 24 can move upward or downward under the drive of the cylinder 23. A plurality of connecting rods 25 are movably arranged on the connecting plate 24. A driving motor 26 is installed on the connecting rod 25. A cutting knife 27 is connected to the power output end of the driving motor 26. When the driving motor 26 is started, the driving motor 26 drives the cutting knife 27 to rotate to achieve cutting of the plastic pipe.

[0043] The position of the connecting rod 25 can be adjusted. The connecting rod 25 can be fixed at any position of the connecting plate 24 by means of a fixing bolt. By setting the connecting rod 25 at different positions, the distance between adjacent connecting rods 25 can be changed, thereby changing the distance between adjacent cutting knives 27 to achieve cutting of plastic pipes of different lengths. The surface of the connecting plate 24 can be provided with a scale to facilitate measuring the distance between the connecting rods.

[0044] Example 3

[0045] On the basis of implementation 2, in this embodiment, the dust collection mechanism 3 includes a dust box 31 and a suction fan 32. The dust box 31 is arranged at the bottom of the box body 1 and is connected to the collection chamber 11. The suction fan 32 is connected to the dust box 31. The suction fan 32 is turned on to collect the dust generated during cutting.

[0046] Optionally, a filter adsorption net for filtering and adsorbing dust is provided inside the dust box 31. One end of the dust box 31 is connected to the collection chamber 11, and the other end is connected to the suction fan 32 through an air duct. The power provided by the suction fan 32 is used to make the air in the collection chamber 11 enter the dust box 31, and the dust entering the dust box 31 is filtered and adsorbed by the filter adsorption net. The filter adsorption net can be replaced after using it for a period of time. It is convenient to collect and use.

[0047] Of course, other types of dust collection mechanisms 3 may also be used, and those skilled in the art may configure them according to actual needs, and the embodiments of the present application do not limit this.
