[0031] like Figures 1 to 5 As shown, a cutting device for plastic processing in one embodiment of the present invention includes: a frame 1, a cutting line 101, a retractable protective assembly 2, and a filter purification assembly 3.

[0032] like Figure 1 As shown, a cutting wire 101 is mounted on one side of the frame 1. The plastic is cut by the relative movement between the cutting wire 101 and the plastic.

[0033] like Figure 1 As shown, a pair of symmetrically distributed wire guides 102 are fixedly mounted on one side of the frame 1, and the cutting wire 101 is mounted inside the wire guides 102. The wire guides 102 guide and limit the cutting wire 101.

[0034] like Figure 1 As shown, a cutting table 103 is fixedly connected to one side of the frame 1, and a cutting line 101 is set through the cutting table 103. The cutting table 103 can support and limit the plastic to be cut.

[0035] like Figures 1 to 3 As shown, the retractable protective assembly 2 is sleeved on the outside of the cutting line 101. The retractable protective assembly 2 includes a protective cylinder 201, which is fixedly sleeved on the outside of the cutting line 101. The protective cylinder 201 supports, limits, and guides the retractable inner cylinder 202. At the same time, the protective cylinder 201 and the retractable inner cylinder 202 work together to provide safety protection for the cutting line 101, reducing the risk of accidental injury to the cutting line 101.

[0036] like Figures 1 to 4As shown, a fixing ring 204 is fixedly sleeved on the upper end of the protective cylinder 201, and the fixing ring 204 is fixedly connected to the conductor frame 102. The protective cylinder 201 is assembled and fixed by the fixing ring 204.

[0037] like Figures 2 to 3 As shown, a retractable inner cylinder 202 is slidably fitted inside the protective cylinder 201. By retracting the inner cylinder 202 within the protective cylinder 201, the protective cylinder 201 and the retractable inner cylinder 202 can provide safe protection for cutting lines 101 of different lengths.

[0038] like Figures 2 to 3 As shown, a pair of locking bolts 203 are threadedly connected to the outer side of the protective cylinder 201, and the pair of locking bolts 203 are configured to cooperate with the shrinkable inner cylinder 202. The shrinkable inner cylinder 202 is locked and positioned by pressing the outer surface of the shrinkable inner cylinder 202 with the pair of locking bolts 203.

[0039] Preferably, one end of each pair of locking bolts 203 located inside the protective sleeve 201 is in contact with the outer surface of the shrinkable inner sleeve 202. This allows the shrinkable inner sleeve 202 to be locked and positioned by pressing the outer surface of the shrinkable inner sleeve 202 with the locking bolts 203.

[0040] Specifically, a shrink groove matching the shrinkable inner cylinder 202 is provided at the bottom of the protective cylinder 201. The shrink groove serves to guide the shrinkable inner cylinder 202 in its movement and sliding.

[0041] like Figures 2 to 3 As shown, a limiting plate 205 is fixedly connected to one end of the shrinkable inner cylinder 202 outside the protective cylinder 201. The limiting plate 205 limits the assembly of multiple ball bearings 206. At the same time, the shrinkable inner cylinder 202 can be limited for storage by the interference between the limiting plate 205 and the storage groove.

[0042] like Figures 2 to 3 As shown, a plurality of evenly distributed ball bearings 206 are rolled on the lower surface of the limiting plate 205, and the bottom surfaces of the plurality of ball bearings 206 are on the same horizontal plane. The rolling of the plurality of ball bearings 206 can reduce the risk of the limiting plate 205 scratching the plastic surface during the sliding process.

[0043] like Figures 2 to 5 As shown, the filter and purification assembly 3 is assembled on one side of the protective cylinder 201. The filter and purification assembly 3 includes an exhaust pipe 301, and the exhaust pipe 301 is fixed to one end of the shrinkable inner cylinder 202 located outside the protective cylinder 201.

[0044] Fixed connection. By evacuating air through the evacuation pipe 301, the air inside the shrinking inner cylinder 202 can be extracted and guided. This not only accelerates the airflow inside the shrinking inner cylinder 202 to assist in cooling the cutting wire 101, but also collects and guides harmful gases or debris generated during the cutting process.

[0045] like Figures 4 to 5 As shown, a guide pipe 302 is fixedly connected to one side of the exhaust pipe 301. The guide pipe 302 serves to connect the exhaust pipe 301 and the purification box 303.

[0046] like Figures 4 to 5 As shown, the side of the guide pipe 302 away from the exhaust pipe 301 is fixedly connected to the purification box 303. The purification box 303, in cooperation with the box cover 306, provides a dust filtration and purification space for the extracted airflow.

[0047] like Figures 4 to 5 As shown, a dust filter 304 is fixedly installed inside the purification chamber 303. The dust filter 304 filters the airflow delivered by the guide pipe 302. The horizontal position of the dust filter 304 is higher than the horizontal position of one end of the guide pipe 302 inside the purification chamber 303. This ensures the reliability of the dust filter 304 in filtering the airflow delivered by the guide pipe 302.

[0048] like Figures 4 to 5 As shown, several sets of adsorption and purification nets 305 are arranged above the dust filter 304, and all sets of adsorption and purification nets 305 are fixedly connected to the inner wall of the purification box 303. The adsorption and purification nets 305 adsorb and purify the harmful gases in the air inside the purification box 303.

[0049] Preferably, the adsorption purification mesh 305 is an activated carbon adsorption mesh.

[0050] like Figures 4 to 5 As shown, a cover 306 is fixedly connected to the top of the purification chamber 303. The cover 306 fastens and seals the purification chamber 303. The cover 306 and the purification chamber 303 cooperate to form a dust filtration and purification cavity. The dust filtration and purification cavity provides dust filtration and purification space for the airflow delivered by the guide pipe 302.

[0051] The top of the cover 306 is provided with an assembly guide hole. The assembly guide hole facilitates the flow of filtered and purified gas inside the purification chamber 303.

[0052] In addition, an exhaust fan can be installed inside the air guide hole. By setting the exhaust fan, the air in the purification box 303, the air guide pipe 302 and the air extraction pipe 301 can be extracted and guided. The exhaust fan is commercially available and can be purchased and used directly.

[0053] like Figures 4 to 5As shown, a conveying pipe 307 is fixedly connected to the top of the cover 306, and the conveying pipe 307 is connected to the assembly guide hole. The conveying pipe 307 serves to connect the assembly guide hole and the exhaust pipe 308.

[0054] like Figures 4 to 5 As shown, an exhaust pipe 308 is fixedly connected to the upper end of the conveying pipe 307, and the top end of the conveying pipe 307 is fixedly connected to the middle position of the exhaust pipe 308. The exhaust pipe 308 assists in the discharge of the gas conveyed by the conveying pipe 307. Both ends of the exhaust pipe 308 are fixedly connected to connecting flanges 309. The connecting flanges 309 connect the exhaust pipe 308 to external pipelines for communication.

[0055] In practical use, the plastic to be cut is placed on the cutting line 101 and moved. The plastic is cut by the relative movement between the cutting line 101 and the plastic. During the cutting process, the locking bolt 203 can be unscrewed to release the locking state of the shrinking inner cylinder 202 according to the thickness of the plastic to be cut, and the shrinking inner cylinder 202 can be extended out of the protective cylinder 201. After adjustment, the locking bolt 203 is tightened to lock the shrinking inner cylinder 202. Thus, the cooperation between the protective cylinder 201 and the shrinking inner cylinder 202 can protect plastics of different thicknesses during cutting.

[0056] In addition, the limiting plate 205 and the ball bearing 206 can be used to assist in limiting and guiding the plastic to be cut on the cutting table 103, thereby improving the stability of the plastic cutting process.

[0057] Meanwhile, an exhaust fan can be installed in the assembly guide hole or an external air extraction system can be connected through the connecting flange 309. By extracting air from the purification box 303, the guide pipe 302 and the extraction pipe 301, not only can the cutting line 101 be cooled, but also harmful gases or debris generated during the cutting process can be collected. The collected harmful gases or debris can be filtered and discharged through the dust filter 304 and the adsorption purification screen 305, thereby improving the environmental friendliness of plastic cutting.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
