Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air compressors, in particular to a screw air compressor for laser cutting. Background Technique
[0002] Laser cutting utilizes the property of high power density of the laser beam to converge the laser onto a very small light spot, rapidly heating the material to make it reach the boiling point and vaporize to form a space. Then, by moving the laser beam on the material surface, cutting is achieved to complete the cutting of the processed object. In addition to a laser that can provide high energy, auxiliary gas is an indispensable substance for completing the cutting process. The main types of auxiliary gas are oxygen, nitrogen, and compressed air. Compressed air is easier to obtain and cheaper than oxygen and nitrogen. The quality of compressed air has a very direct impact on the quality of metal laser cutting.
[0003] Upon inquiry, the publication number: CN214837109U discloses a screw air compressor for laser cutting, which includes a machine body, a male rotor and a female rotor arranged inside the machine body. The two ends of the female rotor are respectively provided with female rotor bearings, and the two ends of the male rotor are respectively provided with male rotors. A linkage bearing that abuts against the female rotor bearing is arranged on the main transmission shaft of the male rotor. An air inlet and an oil injection nozzle are arranged at the top of one end of the machine body. A double-layer filter screen is arranged on the air inlet, and an air outlet is arranged at the other end of the machine body. An oil-gas separation chamber is arranged inside the air outlet end of the machine body. Since a double-layer detachable filter screen is arranged on the air inlet, the setting of a separate filter is reduced, the cost is lowered, and it is convenient to replace the filter screen; the setting of the oil injection nozzle enables the oil to flow inside the male and female rotors, which can reduce the wear of the male and female rotors; the setting of the oil-gas separation chamber can separate the compressed air and the oil, so that the oil can flow back to the bearings for repeated use, greatly reducing the cost.
[0004] Based on the above-mentioned prior art, the currently existing screw air compressors for laser cutting still have the following problems. Traditional air compressors are often fixedly installed in the laser cutting system, making it difficult to meet the requirements of different working scenarios, and the transportation process is cumbersome. Therefore, the utility model provides a screw air compressor for laser cutting. Content of the Utility Model

Detailed Embodiment
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0024] A screw air compressor for laser cutting, including a screw air compressor body 1, characterized in that: a moving mechanism 2 is arranged at the bottom of the screw air compressor body 1 for facilitating the movement of the screw air compressor, and the moving mechanism 2 includes:
[0025] A fixing unit 21, arranged at the bottom of the screw air compressor body 1 and used for supporting the screw air compressor body 1;
[0026] The lifting unit 22 is arranged inside the fixed unit 21 and includes a connecting shaft 221. At both the front and rear ends of the connecting shaft 221, a first lifting rod 222 and a second lifting rod 223 are hingedly installed. At the left end of the first lifting rod 222, a first guide seat 224 is hingedly installed, and at the left end of the second lifting rod 223, a second guide seat 225 is hingedly installed. Sliding components 3 are arranged at the right ends of both the first lifting rod 222 and the second lifting rod 223.
[0027] In this embodiment, the lifting unit 22 further includes a rotating sleeve 228 rotatably sleeved on the outer circle of the connecting shaft 221. A hydraulic rod 227 is fixedly installed on the surface of the rotating sleeve 228. One end of the hydraulic rod 227 is hingedly installed with a fixed seat 226. A bottom plate 229 is fixedly installed at the bottom of the second guide seat 225. Universal wheels 2210 are fixedly installed at the four corners of the bottom of the bottom plate 229.
[0028] When the hydraulic rod 227 operates to push and pull, the connecting shaft 221 is pushed and pulled through the rotating sleeve 228. The connecting shaft 221 drives a scissor-like movement between the first lifting rod 222 and the second lifting rod 223. At this time, the slider 33 slides inside the slide rail 31. The movement of the first lifting rod 222 and the second lifting rod 223 drives the bottom plate 229 and the four universal wheels 2210 to perform a lifting movement, thereby realizing the movement of the screw air compressor.
[0029] When the bottom plate 229 and the universal wheels 2210 descend, the universal wheels 2210 contact the ground to support the screw air compressor and make it move. When the bottom plate 229 and the universal wheels 2210 rise, the adjusting anchor 212 contacts the ground and the universal wheels 2210 are separated from the ground to fix the position of the screw air compressor.
[0030] In this embodiment, the sliding component 3 includes a connecting seat 32 hingedly installed at the right ends of the first lifting rod 222 and the second lifting rod 223. A slider 33 is fixedly installed at the bottom of the connecting seat 32. A number of balls 34 are installed at both the top and bottom of the slider 33. And a slide rail 31 is sleeved outside the slider 33, and the slider 33 slides inside the slide rail 31.
[0031] A number of balls 34 are installed at both the top and bottom of the slider 33, and the slider 33 slides inside the slide rail 31 through a number of balls 34. Thus, the number of balls 34 reduces the friction for the movement of the slider 33, making the movement of the slider 33 smoother and extending the service lives of the slider 33 and the balls 34.
[0032] In this embodiment, the fixing unit 21 includes a base 211 fixedly installed at the bottom of the screw air compressor body 1. A push rod 213 is fixedly installed at the top of the base 211, and the first guide seat 224 is fixedly installed at the top of the inner cavity of the base 211. Four adjusting feet 212 are threadedly inserted and installed at the bottom of the base 211, and are installed in a rectangular array at the four corners of the bottom of the base 211.
[0033] The user rotates the adjusting feet 212 to achieve the adjustable height of the adjusting feet 212, thereby achieving the adjustable levelness of the screw air compressor.
[0034] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0035] During operation, the hydraulic rod 227 operates to push and pull. By rotating the sleeve 228, the connecting shaft 221 is pushed and pulled. The connecting shaft 221 drives a scissor-like movement between the first lifting rod 222 and the second lifting rod 223. At this time, the slider 33 slides inside the slide rail 31. The movement of the first lifting rod 222 and the second lifting rod 223 drives the bottom plate 229 and the four universal wheels 2210 to perform a lifting movement. When the bottom plate 229 and the universal wheels 2210 descend, the universal wheels 2210 contact the ground to support the screw air compressor and make it move. When the bottom plate 229 and the universal wheels 2210 ascend, the adjusting feet 212 contact the ground and the universal wheels 2210 are separated from the ground, fixing the position of the screw air compressor.
