The working principle is as follows:
in the process of using the device, the cutting length of the polyethylene pipe is set through the cutting length setting mechanism, so that subsequent repeated cutting operation in batches is facilitated. Specifically, the pipe top plate 17 is driven to move by the top plate moving driving unit, because the zero-scale end of the graduated scale 16 is aligned with the position of the cutting tool 2, the stopped position of the pipe top plate 17 corresponds to the scale reading of the graduated scale 16 right below, and the end of the polyethylene pipe needs to be supported on the pipe top plate 17 when the polyethylene pipe is subsequently cut, so that the reading is the length of the polyethylene pipe cut. In the process of driving the pipe top plate 17 by the top plate moving driving unit, firstly, the handle 19 is shaken by shaking, the ball screw 18 supported by the bearing is driven, because the nut pair 20 is fixedly connected with the moving block 22 by the connecting rod 23, the nut pair 20 cannot rotate, when the ball screw 18 rotates, the nut pair 20 moves along the axial direction of the ball screw 18 by thread fit, in the process, the moving block 22 is also driven to move along the slide rail 21, the graduated scale 16 is also driven to move along the extending direction of the graduated scale 16, and the length for cutting the polyethylene pipe is set when the pipe is moved to a proper position. Fix the polyethylene pipe through tubular product fixed establishment afterwards, prevent that the polyethylene pipe slippage when being cut from influencing normal cutting work. It is specific, the one end that the polyethylene pipe that the messenger waited to cut needs the cutting stretches into inside the tubular product sleeve 12 in the tubular product fixed establishment, and cross 13 tops of lip-pad piece and make the tip of polyethylene pipe support on tubular product roof 17, compress tightly 14 the inside polyethylene pipe of tubular product sleeve 12 through tubular product in the fixed unit afterwards and fasten, then fix, wherein slipmat 15 is the rubber pad, play skid-proof effect, it is better to the fixed effect that compresses tightly of polyethylene pipe to make pressure bolt 14, and slipmat 15 can not rip polyethylene pipe outer wall for the rubber pad. The supporting cushion block 13 is an arc concave surface, which plays a role in supporting the polyethylene pipe, and the polyethylene pipe is kept horizontally placed on the inner wall of the pipe sleeve 12 and supported by the supporting cushion block 13, so that the polyethylene pipe can be cut subsequently. And then the cutting tool 2 fixed by the tool supporting unit is driven by the tool feeding unit in the pipe cutting mechanism to cut the polyethylene pipe, wherein the polyethylene pipe is cut more labor-saving by the cooperation between the tool feeding unit and the tool supporting unit. Specifically, the lower end of the slide rod 5 in the cutter supporting unit is connected to the cutting cutter 2, and the specific connection means may be bolt fastening or the like, which is a known means. When a polyethylene pipe is cut, the swing arm 8 is pulled by the swing handle 9 in the cutter feeding unit to swing downwards, so that the downward pressing bulge 11 on the swing arm 8 is pressed on the top 10, the swing arm 8 is continuously pulled by the swing handle 9 to swing downwards, the downward pressing bulge 11 pushes the top 10 downwards, the sliding rod 5 in the cutter supporting unit is driven to slide downwards along the guide supporting cylinder 3, and the cutting cutter 2 is driven to move downwards and cut the polyethylene pipe. In the process, because the upper end of the ejector 10 is an arc-shaped surface, and the lower end of the downward pressing bulge 11 is an arc-shaped surface, when the downward pressing bulge 11 pushes the ejector 10 downwards, the arc-shaped surfaces of the downward pressing bulge and the arc-shaped surface slide relatively, so that the swinging arm 8 presses the sliding rod 5 to move downwards more labor-saving, and the swinging arm 8 presses the sliding rod 5 to move downwards by utilizing the lever principle, so that the labor-saving effect is also achieved. When loosening swing arm 8 afterwards, under the effect of the restoring force of compressed compression spring 7, promote limiting plate 6, drive slide bar 5 rebound then and resume initial position, make cutting tool 2 also resume initial position, the convenient cutting work to follow-up pipe fitting. Wherein the support arm 4 serves as a support for the guide support cylinder 3. To sum up, this device can carry out fixed length cutting in batches to the polyethylene pipe, and is more stable to the fixed cutting operation that makes of polyethylene pipe, improves cutting work efficiency.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
