Description

Technical Field

[0001] The invention relates to the technical field of cold dryers for laser cutting machines, and more specifically, to a special cold dryer for laser cutting machines. Background Art

[0002] In the prior art, cold dryers dedicated to laser cutting machines, as an important auxiliary equipment, play a key role in ensuring the gas quality during the laser cutting process. Such cold dryers mainly rely on the cold source of the copper drum refrigerator to cool the compressed air, and through the cooling process, ensure the accuracy and effect of laser cutting. However, the cold dryers commonly used in the market currently have a significant defect, that is, they cannot dynamically adjust the cooling effect according to the actual gas flow and pressure changes. This fixed cooling mode not only cannot adapt to the differentiated requirements of different cutting processes for gas quality, but may also lead to problems such as energy waste or insufficient cooling, thereby affecting the efficiency and quality of the entire laser cutting process.

[0003] Existing cold dryer equipment also has obvious deficiencies in the adjustment of the filter element fixing pressure. As the core component of the cold dryer, the filter element's fixing pressure directly affects the filtering effect and service life. However, the current designs of most cold dryers do not fully consider the adjustability of the filter element fixing pressure. As a result, in actual use, it is difficult for operators to optimize the working state of the filter element according to different working conditions and gas characteristics. The non-adjustability of the fixed pressure may not only affect the filtering effect of the filter element, but may also cause problems such as premature damage to the filter element or gas leakage. This design limitation seriously affects the convenience of use and maintenance efficiency of the cold dryer, increases the operating cost of the equipment, and may also affect the reliability and work efficiency of the entire laser cutting system due to the instability of the filter element performance.

[0037] Working principle: When existing equipment cools the laser cutting machine, it is first necessary to generate cold air through a cold source, and then dehumidify and pressurize the air before passing it into the laser cutting machine for cooling. Although this method is direct, it cannot effectively remove moisture from the air. Therefore, the present application separates the air generated by the cold source and the air passed into the laser cutting machine, and the air passed into the air compressor 2 is in a relatively dry state. The compressed air is then cooled through non-contact heat exchange, and the cold air is dehumidified for a second time. Therefore, it can be ensured that the moisture content of the air passed into the laser cutting machine is further reduced to meet the requirements.

[0038] First, relatively dry air is introduced into the air compressor 2, and then the air is compressed by the air compressor 2. At this time, the cold air generated in the cold source is introduced into the pressurized shell 1 through the cold inlet pipe 33, and then the cold air is deflected multiple times under the action of multiple baffles 31, so it will fully exchange heat with the control pipe 5 and the heat exchange pipe 7. The compressed air generated by the air compressor 2 is introduced between the two baffle sleeves 6 and the partition plate 4 through the air inlet pipe 3, and then introduced into multiple control pipes 5. At this time, the opening pressures of the multiple control pipes 5 are different. First, when the pressure reaches a smaller opening pressure When the air pressure in the pressure regulating pipe 8 is increased, the seal in the corresponding pressure regulating pipe 8 will be released, and then the compressed air will flow into the pressure regulating pipe 8 through the gap between the sealing disk 17 and the sealing head 16, and then be discharged to the space at both ends of the pressurized shell 1 through the air outlet 22, and then flow into the heat exchange pipe 7 to exchange heat with the cold air again, thereby completing the heat exchange process, and then be discharged through the air outlet pipe 36. At this time, a cycle is completed. When the cooling demand of the laser cutting machine increases, the pressure provided by the air compressor 2 increases, more pressure regulating pipes 8 will be opened, and then the heat exchange flow rate will be increased to meet the needs of the laser cutting machine.

[0039] When it is necessary to change the opening pressure in the pressure-regulating tube 8, first, the handle 27 can be turned to drive the rotation of the telescopic tube 15, and the hexagonal sleeve 10 will rotate accordingly. Since the follower sleeve 11 is slidably connected to the hexagonal sleeve 10, the follower sleeve 11 and the internal tube 9 can be driven to rotate synchronously, and the internal tube 9 is threadedly connected to the inner wall of the pressure-regulating tube 8, so the position between the internal tube 9 and the sealing disk 17 can be changed. Since the follower disk 101 is rotatably connected in the follower groove 19, the tension spring 18 can be driven to change position, thereby changing the tension of the tension spring 18, and then changing the opening pressure. When the follower sleeve 11 moves to fit on the limit disk 12, the sealing head 16 is in a fixed state at this time, so the sealing head 16 and the sealing disk 17 can be in a fixed and sealed state, and it will not open.

[0040] When it is necessary to sample the corresponding pressure regulating tube 8 to detect the moisture content, the insertion head 25 is abutted against the insertion hole 26 before it is opened. At this time, the insertion hole 26 is in a sealed state. When the sealing head 16 is in an open state, the air flows into the connecting hole 21 through the diffusion hole 20 and then is discharged. It will not be discharged through the sampling tube 23. When the sampling tube 23 rotates so that the middle disk 29 abuts against the stop disk 28, the sampling tube 23 and the telescopic tube 15 are in a threaded fixed state, and then the gas will flow into the sampling tube 23 through the insertion tube, and then be collected by the sampling tube 23, thereby completing the moisture detection process.

[0041] In order to enhance the heat transfer effect, add a baffle mechanism, please refer to Figure 1 to Figure 2 The baffle mechanism includes a baffle 31, a spoiler 32, a cold inlet pipe 33, a cold outlet pipe 34 and a drag reduction block 35. A plurality of baffles 31 are provided, and the plurality of baffles 31 are respectively and alternately installed on the control pipe 5 and the heat exchange pipe 7. A plurality of spoilers 32 are respectively and equidistantly arranged on both sides of each baffle 31. One end of the cold inlet pipe 33 and the cold outlet pipe 34 are connected to the pressurized shell 1, and the other end of the cold inlet pipe 33 and the cold outlet pipe 34 are connected to the cold source. The drag reduction block 35 is installed on the lower end surface of the partition plate 4.

[0042] Working principle: The cooling air can flow into the pressurized shell 1 through the cold inlet pipe 33, and then the sufficient heat exchange between the multiple control pipes 5 and the heat exchange pipes 7 is ensured through multiple baffles 31. Then, the flow direction of the air is guided under the action of multiple spoilers 32. The air after the heat exchange is completed flows into the cold source through the cold outlet pipe 34 and is re-cooled, thus performing the circulating cooling process.

[0043] See also Figures 7 to 10In order to realize the fixed pressure adjustment of the filter sleeve 39, an additional mounting mechanism is provided. The mounting mechanism includes an air outlet pipe 36, an outer shell 37, a top plate 38, a filter sleeve 39 and a vertical rod 40. The air outlet pipe 36 is mounted on the lower end surface of the pressurized shell 1, the top plate 38 is fixedly connected to the air outlet pipe 36, the outer shell 37 is sleeved on the top plate 38, the vertical rod 40 is mounted on the top plate 38, an outer sleeve 301 is provided on the top plate 38, and the filter sleeve 39 is mounted on the top plate 38 and the outer shell 37. A constant pressure rod 41 is provided on the vertical rod 40, and a constant pressure pipe 42 is slidably provided on the constant pressure rod 41, and the constant pressure pipe 42 abuts against the lower end surface of the shell 37, and a cone head 43 is provided on the lower end surface of the constant pressure rod 41, and transverse holes 44 are equidistantly provided on the side wall of the constant pressure pipe 42, and each transverse hole 44 is slidably provided with a push rod 45, and a plurality of thread grooves 46 are equidistantly provided on the side wall of the constant pressure rod 41, and a plurality of push rods 45 abut against the thread grooves 46, respectively, and the constant pressure pipe 4 A plurality of annular holes 47 are equidistantly provided on the side wall of the filter 2, a mounting sleeve 48 is threadedly provided in each annular hole 47, a compression spring 49 is provided on each mounting sleeve 48, a traverse head 50 is provided on the compression spring 49, the traverse head 50 abuts against the push rod 45, an internal disk 51 is provided in the compression spring 49, a push rod 52 is slidably provided in each mounting sleeve 48, one end of the push rod 52 abuts against the internal disk 51, a synchronous sleeve 53 is provided on the other end of the push rod 52, a lifting sleeve 54 is threadedly provided on the constant pressure pipe 42, a push sleeve 55 is coaxially provided in the lifting sleeve 54, a thrust bearing 56 is provided on the push sleeve 55, the synchronous sleeve 53 abuts against the thrust bearing 56, a fixing sleeve 57 is provided on the constant pressure pipe 42, a transparent tube 58 is connected to the outer shell 37, and the transparent tube 58 is respectively connected to the two sides of the filter sleeve 39, two sealing bolts 59 are threadedly provided on the upper end of the transparent tube 58, and a bottom bolt 60 is threadedly provided on the lower end of the transparent tube 58.

[0044] Working principle: when it is necessary to install the corresponding filter sleeve 39, first install the filter sleeve 39 on the top plate 38, then pass the outer shell 37 through the vertical rod 40 so that the outer shell 37 is pressed on the filter sleeve 39 and the top plate 38, and then apply pressure to the outer shell 37 through the constant pressure pipe 42, thereby ensuring the sealing of the filter sleeve 39, and then the air will filter out the moisture through the filter sleeve 39 and gather on the lower end surface of the outer shell 37, and then the compressed cold air will flow into the laser cutting machine through the outer sleeve 301 for cooling, thereby completing a cycle process. When a lot of water accumulates in the outer shell 37 for a long time, the water can be discharged by loosening the sealing bolts 59 and the bottom bolts 60 when the machine is shut down, thereby completing the cycle process. The filter sleeve 39 also needs to be replaced regularly after a long period of use.

[0045] When it is necessary to adjust the fixed pressure according to the filter sleeve 39, first, since the push rod 45 is slidably connected in the transverse hole 44, and one end of the push rod 45 abuts on the transverse head 50, the other end of the push rod 45 is threadedly connected in the thread groove 46, at this time, it can be rotated along the thread groove 46 to make the constant pressure tube 42 abut on the outer shell 37. When the abutting force is greater than the force of multiple compression springs 49, the push rod 45 will slide backward, thereby releasing the connection between the push rod 45 and the thread groove 46, so that the corresponding fixed pressure can be adjusted. Since the transverse hole 44 and the push rod 45 have a certain friction, the constant pressure tube 42 will not slip when it is not connected.

[0046] When it is necessary to adjust the elastic force of the compression spring 49, by rotating the lifting sleeve 54, since the lifting sleeve 54 is threadedly connected to the constant pressure tube 42, it will drive the movement of the thrust bearing 56 and the synchronous sleeve 53, and the multiple push rods 52 will also move synchronously. At this time, the push rods 52 will abut against the inner disk 51, thereby causing the compression spring 49 at the upper end to be compressed, thereby changing the pressure of the compression spring 49, and then changing the unlocking pressure of the multiple push rods 45 and the threaded grooves 46.

[0047] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
