Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a cutting machine for processing plastic pipes. Background Art

[0002] Material pipes are generally made of synthetic resin, that is, polyester as raw material, with the addition of stabilizers, lubricants, plasticizers, etc., and are extruded in a pipe making machine using a "plastic" method. Due to its light weight, corrosion resistance, beautiful appearance, no bad odor, easy processing, and convenient construction, its use in the field of construction engineering has become more and more widespread. During use, plastic pipes need to be cut into different lengths according to actual needs. Existing plastic pipes are generally cut manually by workers using scissors, which is inefficient. There is also a process of cutting plastic pipes using a cutting machine. When workers use the cutting machine to cut the plastic pipe, they generally need to use a ruler to measure the required size and then cut it. If the plastic pipe is not fixed properly, the cut size may be inaccurate, which not only affects work efficiency but also leads to waste of pipe materials.

[0003] The patent with the current announcement number CN220680905U discloses a plastic pipe cutting machine, comprising a base, a gantry fixedly mounted above one end of the base, a cutting blade slidably mounted within the gantry, a cylinder fixedly mounted above the gantry, the output end of the cylinder passing through the gantry and fixedly connected above the cutting blade, a tape measure slot formed on one side of the base located on the gantry, a tape measure mounted within the tape measure slot, a guide slot formed on one side of the base located on the tape measure slot, a guide rod slidably mounted within the guide slot, one end of the guide rod fixedly connected to a connecting rod. This device is equipped with a tape measure, which allows the user to effectively and intuitively view the required cut size when cutting plastic pipes, making the cut size more accurate. The clamp effectively secures the plastic pipe, preventing it from shaking during cutting, further improving the accuracy of the cut size.

[0004] Although the above device solves the problem of measurability during cutting of plastic pipes, it still has the following shortcomings:

[0005] The device uses a threaded column to clamp the plastic pipe, and the nut needs to be turned multiple times, which is inconvenient. Moreover, when the plastic pipe is cut for the first time, the size needs to be measured with a tape measure. Since it does not have a temporary fixing component for the size, the plastic pipe needs to be measured again when it is cut for the second time, which causes inconvenience. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a cutting machine for processing plastic pipes, which is convenient for clamping the plastic pipes during cutting and for limiting the size.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cutting machine for processing plastic pipes, comprising a cutting machine body and a quantitative rod connected to the end of the cutting machine body, the top of the cutting machine body is fixedly connected to two groups of symmetrically arranged brackets, the top of the bracket is fixedly connected to a top plate, the bottom surface of the top plate is connected to a clamping mechanism, the clamping mechanism comprises an electric push rod, the electric push rod is fixedly connected to the top surface of the top plate, and the output end is fixedly connected to a cross bar through the set top plate, the bottom of the cross bar is fixedly connected to a number of connecting rods, the bottom of the connecting rod is fixedly connected to an extrusion block, an extrusion groove is provided in the extrusion block, and the outer wall of the quantitative rod is connected to a limiting piece.

[0011] Furthermore, the blocking member includes a U-shaped baffle, and the two ends of the cross bar are fixedly connected to end blocks, and a limiting groove is opened in the end block. A slider fixedly connected to the two ends of the U-shaped baffle is slidably connected in the limiting groove, and the inner wall of the U-shaped baffle is against the outer wall of the card plate and the cross bar.

[0012] Furthermore, the cross sections of the limiting groove and the sliding block are T-shaped or wedge-shaped.

[0013] Furthermore, the top surface of the crossbar is fixedly connected to two symmetrically arranged guide rods, which pass through the top plate and are slidably connected thereto.

As a result, when cutting subsequent pipes of the same size, there is no need to adjust the size again, which is suitable for batch cutting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] like Figures 1 to 5 As shown, a cutting machine for processing plastic pipes includes a cutting machine body 1 and a quantitative rod 2 connected to the end of the cutting machine body 1. Two groups of symmetrically arranged brackets 3 are fixedly connected to the top of the bracket 3, a top plate 31 is fixedly connected to the top of the top plate 31, and a clamping mechanism 4 is connected to the bottom of the top plate 31. The clamping mechanism 4 includes an electric push rod 404, the electric push rod 404 is fixedly connected to the top surface of the top plate 31, and the output end is fixedly connected to a cross bar 401 through the set top plate 31, and a plurality of connecting rods 402 are fixedly connected to the bottom of the connecting rod 402. An extrusion block 403 is fixedly connected to the bottom of the connecting rod 402, and an extrusion groove is provided in the extrusion block 403. The outer wall of the quantitative rod 2 is connected to a limiting member 6.

[0026] like Figure 1 As shown, the plastic pipe processing cutting machine in the present invention is similar in structure to the existing plastic pipe cutting machine, such as the patent with announcement number CN220680905U discloses a plastic pipe cutting machine. The main improvement of the present invention is to facilitate the clamping of the plastic pipe during cutting and to facilitate the limitation of the size, such as Figures 1 to 5 As shown, when the plastic pipe processing cutting machine in the present invention is in use, the worker places the pipe on the cutting machine body 1, determines the size through the quantitative rod 2, and starts the electric push rod 404, so that the output end of the electric push rod 404 descends on the top plate 31, driving the cross bar 401 to descend, and then the several connecting rods 402 and the extrusion block 403 squeeze the pipe. The extrusion groove on the extrusion block 403 can squeeze the pipe well to achieve clamping; before cutting, the limiter 6 is operated to fix the extended length of the quantitative rod 2, so that subsequent pipes of the same size do not need to be adjusted in size again when cutting, which is suitable for batch cutting. After the cutting is completed, the electric push rod 404 rises, the extrusion block 403 rises, and the pipe is moved. The electric push rod 404 drives the extrusion block 403 to descend to achieve clamping of the pipe. This is repeated to complete the cutting of the pipe.

[0027] By coordinating the electric push rod 404, the cross bar 401, the extrusion block 403 and the extrusion groove, the pipe can be conveniently clamped. When the cross bar 401 is lowered, several extrusion blocks 403 can be lowered at the same time, so that the same power source can drive multiple extrusion blocks 403 to clamp, and the clamping effect is good.

[0028] like Figure 1 、 Figure 3 and Figure 4 As shown, the limiter 6 includes a fixed ring 601, the top surface of which is fixedly connected to a plurality of spring plates 603, the outer wall of the fixed ring 601 is threadedly connected to a threaded ring 602, the inner wall of the threaded ring 602 is against the outer wall of the spring plate 603, and the inner wall of the spring plate 603 is against the outer wall of the quantitative rod 2.

[0029] Specifically, when it is necessary to limit the length of the quantitative rod 2, it is only necessary to rotate the threaded ring 602 to drive the threaded ring 602 to rotate and move on the outer wall of the fixed ring 601, so that the inner wall of the threaded ring 602 and the outer wall of the spring plate 603 gradually collide with each other, and then the spring plate 603 can clamp the outer wall of the quantitative rod 2, so that the friction between the spring plate 603 and the outer wall of the quantitative rod 2 increases, and the quantitative rod 2 is fixed, so that when cutting subsequent pipes of the same size, there is no need to adjust the size again, which is suitable for batch cutting.

[0030] like Figure 3 and Figure 4 As shown, the outer wall of the threaded ring 602 is fixedly connected with a handle 604. The setting of the handle 604 can facilitate the rotation of the threaded ring 602.

[0031] like Figure 2 As shown, a sliding groove is provided in the crossbar 401, and the top surfaces of the plurality of connecting rods 402 are fixedly connected with a clamping plate 8 which is slidably connected to the sliding groove, and the outer wall of the clamping plate 8 is connected with a blocking member.

[0032] like Figure 2 and Figure 5 As shown, the blocking member includes a U-shaped baffle 9, and the two ends of the cross bar 401 are fixedly connected with end blocks 7, a limiting groove 71 is provided in the end block 7, and a slider 91 fixedly connected to the two ends of the U-shaped baffle 9 is slidably connected in the limiting groove 71, and the inner wall of the U-shaped baffle 9 is against the outer wall of the clamping plate 8 and the cross bar 401.

[0033] Specifically, when the extrusion block 403 needs to be replaced, it is only necessary to slide the U-shaped baffle 9 to drive the sliders 91 at both ends of the U-shaped baffle 9 to slide in the limit groove 71 in the end block 7, thereby removing the restriction on the outer wall of the card plate 8. At this time, the card plate 8 can be slid out of the slide groove in the cross bar 401. With this arrangement, several extrusion blocks 403 can be replaced.

[0034] like Figure 2 and Figure 5 As shown, the cross-sections of the limiting groove 71 and the slider 91 are T-shaped or wedge-shaped. The T-shaped or wedge-shaped arrangement can prevent the slider 91 from sliding out of the limiting groove 71. Both options can provide multiple options for the manufacturer.

[0035] like Figure 1 and Figure 2 As shown, the top surface of the crossbar 401 is fixedly connected to two symmetrically arranged guide rods 5, which penetrate the top plate 31 and are slidably connected thereto. The arrangement of the guide rods 5 can facilitate the downward movement of the crossbar 401 to be more stable.

[0036] like Figure 1 and Figure 2 As shown, the extrusion block 403 is a rubber block. The rubber block is provided to prevent the extrusion block 403 from damaging the outer wall of the pipeline.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
