[0002] In order to facilitate the special-shaped cutting of engineering plastics, a wire saw is usually used for cutting. The cutting tool of the wire saw is a high-speed reciprocating diamond wire, which cuts the engineering plastics through the high-speed friction between the diamond wire and the plastic.

[0003] During the friction cutting process between the wire saw and engineering plastics, a certain amount of plastic debris and dust will be generated. Most of the debris is scattered on the workbench of the wire saw. In order to facilitate continuous production, workers usually use blowing equipment to blow the debris on the workbench to the ground, which is not only inconvenient for cleaning after work, but also the dust is not conducive to the physical and mental health of the workers.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1 , which is an engineering plastic cutting device that is easy to use disclosed in an embodiment of the utility model, includes a workbench 1 and a wire saw sanding line 2. A through hole 11 is opened on the workbench 1, and the wire saw sanding line 2 passes through the through hole 11. A support frame 3 is fixedly installed on the workbench 1. A dust removal port 4 is fixedly installed under the support frame 3 and the through hole 11. Please refer to Figure 2 The dust removal port 4 is trumpet-shaped, and the two dust removal ports 4 are mirror-symmetrical. The trumpet mouths of the dust removal ports 4 are connected to the through hole 11. The wire saw sand wire 2 passes through the dust removal port 4 along the axis of the dust removal port 4. The side of the dust removal port 4 is fixedly connected with a dust extraction pipe 51. Please refer to Figure 1 The dust extraction pipe 51 is connected to the filter box 52. Please refer to Figure 3 A filter element 521 is installed in the filter box 52 , and a dust extraction pump 53 is installed on the side of the filter element 521 away from the dust extraction pipe 51 .

[0034] Specifically, two dust removal ports 4 are installed on the wire sawing line 2 of the wire sawing machine. The dust removal port 4 is connected to the filter box 52 through the dust extraction pipe 51. The filter box 52 is provided with a filter element 521 and a dust extraction pump 53. During the reciprocating operation of the wire sawing line 2, the debris generated by friction is brought upward or downward, and the dust extraction pump 53 exhausts air to the outside, making the filter box 52 under negative pressure, and then making the dust extraction pipe 51 and the dust removal port 4 under negative pressure, so that the debris brought out by the wire sawing line 2 is sucked into the filter box 52, filtered by the filter element 521, and then falls into the filter box 52.

[0035] In this way, the two positions where the wire saw sanding line 2 discharges debris are evacuated through the two dust removal ports 4, so that the discharged debris is sucked into the filter box 52, reducing the debris scattered on the workbench 1 and in the air, and reducing the cleaning of the workbench 1 and the harm of dust to the staff.

[0036] In some feasible embodiments, the workbench 1 and the wire saw sanding wire 2 are the existing technologies of the wire saw machine tool, which will not be repeated here. The dust removal port 4 is a trumpet-shaped rotating body structure, the filter box 52 is a sealed rectangular box, the filter element 521 can be selected as a filter net or a dust bag, the dust extraction pipe 51 and the dust extraction pump 53 are respectively located on both sides of the filter element 521, and the dust extraction pump 53 discharges gas to the outside of the filter box 52. The dust removal port 4 serves as the gas input end to carry plastic debris into the filter box 52 and is blocked by the filter element 521. Then the gas is discharged through the dust extraction pump 53, and the debris falls on the filter element 521.

[0037] As a specific implementation of a convenient-to-use engineering plastic cutting device provided by the utility model, please refer to Figure 2 One end of the dust removal port 4 away from the bell mouth is fixedly connected with a rubber ring 41, and one end of the rubber ring 41 away from the dust removal port 4 is fixedly installed with two connecting half rings 42. The two connecting half rings 42 are fixedly connected with bolts, and the wire saw sanding wire 2 is located between the connecting half rings 42.

[0038] In general, by setting the rubber ring 41 and the connecting half ring 42, one end of the dust removal port 4 is sealed to improve work efficiency. At the same time, the wire saw sanding line 2 is a high-speed reciprocating motion component, which will rub against the rubber ring 41 during the motion and then cut the rubber ring 41 part. After being set to a rubber material, the rubber is a flexible material. When one end of the rubber ring 41 is fixed to the wire saw sanding line 2 by the connecting half ring 42, the end of the rubber ring 41 moves with the wire saw sanding line 2, reducing the possibility of cutting and extending the service life of the rubber ring 41 part.

[0039] Furthermore, the rubber ring 41 is sleeved on the dust removal port 4 , and an adjustable pipe hoop 43 is installed on the outer side of the rubber ring 41 .

[0040] It should be understood that during the reciprocating motion of the wire saw sanding wire 2, the rubber ring 41 is constantly folded and unfolded. When the fatigue limit of the rubber ring 41 is reached, the cracked rubber ring 41 needs to be replaced. An adjustable pipe clamp 43 is provided to fix the rubber ring 41 to facilitate the disassembly and assembly of the rubber ring 41.

[0041] Furthermore, the rubber ring 41 is located at one end of the connecting half ring 42 and covers the inner side of the connecting half ring 42 .

[0042] As it is understood that the rubber ring 41 is a wearing part, the rubber ring 41 covers the inner side of the connecting half ring 42 so that the wire saw sanding wire 2 rubs against the rubber ring 41 to reduce the wear on the connecting half ring 42 .

[0043] As another specific embodiment of the engineering plastic cutting device provided by the utility model, please refer to Figure 1 A bellows section 401 is arranged in the middle of the dust removal port 4 located at the top.

[0044] In combination with specific usage scenarios, according to the different thicknesses of the cut plastic sheets, the height of the dust removal port 4 at the top is also different. By setting the bellows section 401, the dust removal port 4 can be stretched and contracted through the bellows section 401 to facilitate adjustment of the working height of the dust removal port 4, so that the dust removal port 4 is suitable for processing plastic sheets of different thicknesses.

[0045] As a specific implementation of a convenient-to-use engineering plastic cutting device provided by the utility model, please refer to Figure 3 A water tank 522 is provided in the filter box 52 , the dust extraction pipe 51 is inserted into the water tank 522 , and the filter element 521 covers the upper end of the water tank 522 .

[0046] It should be understood that plastic debris is generated during the friction between the online saw sanding wire 2 and the plastic. During the filtering process, the plastic debris may be adsorbed on the filter element 521 in large quantities, causing the filter element 521 to be blocked. By setting up a water tank 522, air flow enters the water, and part of the plastic debris is blocked by the water and remains in the water, reducing the filtering pressure of the filter element 521, thereby reducing the replacement and maintenance work of the filter element 521.

[0047] Furthermore, a filter plate 523 is fixedly installed in the water tank 522 , the filter plate 523 is a porous plate, and the dust extraction pipe 51 passes through the filter plate 523 .

[0048] It should be understood that by providing the filter plate 523, the airflow of the dust extraction pipe 51 is dispersed through the porous structure, the contact between the airflow and water is increased, and the retention effect of water on debris is improved.

[0049] 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 protection scope of the present invention.
