For the convenience of description, if the words "upper", "lower", "left" and "right" appear below, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] Examples, such as Figures 1 to 8As shown, the utility model provides a dustproof and noise-reducing precision cutting machine, including a chassis 1, wherein a cutting system 2 is arranged inside the chassis 1, and the cutting system 2 includes a spindle motor 21, and a spindle 22 and a saw blade 23 are arranged at the power output end of the spindle motor 21. The spindle motor 21 drives the spindle 22 and the saw blade 23 to rotate synchronously, so as to cut the workpiece extending into the cutting system 2. On this basis, the chassis 1 provided by the utility model is a fully enclosed structure, and a front insulating glass 11 and a rear insulating glass 12 are arranged on the front and rear sides thereof, respectively. The cutting system 2 includes an integrated seat 24, and a feed trough 3 and a discharge trough 4 are arranged on the feed side and the discharge side of the integrated seat 24, respectively, which are connected to the two sides of the chassis 1. Furthermore, the integrated seat 24 includes a seat plate 241, and a cutting opening 242 for the saw blade 23 to move up and down is arranged on the seat plate 241, and a plurality of slots are arranged on the top of the seat plate 241 to surround the cutting opening 242. A door-type cover 243 of cloth is provided, and inclined dust suction ports 244 are provided on both sides of the door-type cover 243. A dust suction pipe is provided at the dust suction port 244, and a dust collector is provided at the power end of the dust suction pipe. Dumbbell ports 245 for debris to fall are provided at both ends of the cutting port 242, and the dumbbell ports 245 prevent debris from accumulating near the cutting port 242. A chip box 246 corresponding to the cutting port 242 is provided at the bottom of the seat plate 241, and an inclined tubular groove 247 is provided at the bottom of the chip box 246, and the end of the tubular groove 247 is used to discharge the chips.

[0027] In this device, the hollow glass used on the chassis 1 is made of two (or three) pieces of glass, using a high-strength and high-airtightness composite adhesive to bond the glass pieces to an aluminum alloy frame containing a desiccant, to form a high-efficiency sound-insulating and heat-insulating glass. The hollow glass also has high explosion-proof properties and high safety, and can effectively block the debris splashed by cutting. By using the front hollow glass 11 and the rear hollow glass 12, not only can it be seen through, but it can also effectively improve the sound insulation and noise reduction performance of the device. In addition, the cutting system 2 uses a door-shaped cover 243 as a protection to reduce the range of cutting dust diffusion. The dust is sucked away by a vacuum cleaner and there is a chip box 246 to centrally guide the chips, which is conducive to improving the cleanliness and dustproof performance of the inside of the device.

[0028] In order to improve the practicality of the chassis 1, the chassis 1 provided by the utility model includes a front cabinet 13, a rear cabinet 14, a left side plate 15 and a right side plate 16, the left side plate 15 and the right side plate 16 are both higher than the front cabinet 13 and the rear cabinet 14, a top frame 17 is arranged on the top of the left side plate 15 and the right side plate 16, a top plate 18 is arranged on the top frame 17, a front frame 19 and a rear frame 110 are arranged between the top frame 17 and the front cabinet 13 and the rear cabinet 14, respectively, the front insulating glass 11 and the rear insulating glass 12 are respectively installed on the front frame 19 and the rear frame 110, and an operation panel 111 is arranged on one side of the front frame 19. The chassis 1 adopts a frame structure as a whole, the left side plate 15 and the right side plate 16 adopt a sheet metal structure, and the front insulating glass 11, the rear insulating glass 12 and the top plate 18 are convenient for assembly with the top frame 17, the front frame 19 and the rear frame 110. The front cabinet 13 and the rear cabinet 14 may be provided with door panels, which are convenient for opening to carry out routine maintenance and repair of the specific structure of the cutting system 2 .

[0029] Furthermore, the front frame 19 provided by the utility model is a single-sash structure, and the rear frame 110 is a double-sash structure. Accordingly, the front insulating glass 11 installed on the front frame 19 is a whole surface, reducing the middle frame, which is convenient for observing the working condition of the cutting system 2 inside the chassis 1, and the rear insulating glass 12 installed on the rear frame 110 is double-sided, and its cost is lower than that of the front insulating glass 11, and it has sufficient installation reliability and safety.

[0030] In order to improve the dustproof performance of the device, the front frame 19 and the rear frame 110 provided by the utility model are curved frames, and their front and rear widths gradually increase from top to bottom until they are connected to the front cabinet 13 and the rear cabinet 14. In this way, under the premise of providing sufficient cutting operation space, the internal space of the chassis 1 is reduced from bottom to top, and the range of dust activity is reasonably controlled, which is conducive to improving the dustproof performance of the chassis 1.

[0031] Considering the transmission characteristics of the workpiece from left to right, in order to improve the cutting efficiency of the cutting system 2, the cutting system 2 provided by the utility model provides a corresponding lifting function for the spindle motor 21. Specifically, a strip hole 248 is provided in the horizontal direction of the chip box 246 for the spindle 22 to move up and down, and a vertical guide rail 249 is provided on the outer side of the chip box 246. A lifting seat 25 that slides with it is provided on the guide rail 249. The lifting seat 25 is used to install the spindle motor 21 and a lifting drive cylinder 26 connected to it is provided at the bottom. The lifting drive cylinder 26 drives the lifting seat 25, and the lifting seat 25 rises and falls along the guide rail 249. For example, before the workpiece is transmitted, the spindle motor 21 can be moved downward, and the saw blade 23 leaves the transmission direction of the workpiece. After the workpiece is in place, the lifting drive cylinder 26 drives the spindle motor 21 and the saw blade 23 to gradually rise, thereby cutting the workpiece. The cut workpiece extends out of the discharge chute 4 and is removed.

[0032] In order to improve the feeding efficiency, the feeding trough 3 provided by the utility model includes a trough plate 31, which extends horizontally from the outside of the chassis 1 into the chassis 1, and a supporting plate 32 is provided at the bottom of the trough plate 31, which is nested with the trough plate 31 and connected with the door-shaped cover 243. The supporting plate 32 improves the stability of the trough plate 31 on the one hand, and provides connection between the trough plate 31 and the door-shaped cover 243 on the other hand, which is conducive to the smooth extension of the workpiece into the range where the cutting opening 242 is located.

[0033] In order to improve the discharging performance, one end of the discharging chute 4 provided by the utility model is a folded angle that is folded downward and is spaced apart from the cutting system 2, and the other end of the discharging chute 4 horizontally extends out of the chassis 1. The discharging chute 4 leaves a certain space for the cutting system 2, and leaves a certain angle when the workpiece is extended, so that the workpiece can be smoothly placed on the surface of the discharging chute 4 until the workpiece is cut and removed.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
