Description

Technical Field

[0001] The invention relates to the field of liquid reservoir processing, in particular to a laser cutting device for a liquid reservoir steel pipe. Background Art

[0002] The accumulator is an important part of the compressor, used for storage, gas-liquid separation, filtering, silencing and refrigerant buffering. It is usually assembled between the condenser and the evaporator, close to the condenser. It is mainly used to store liquid refrigerant and absorb moisture from the refrigerant. It is divided into two layers, upper and lower, using a water-absorbing medium. The pressurized refrigerant flows into the accumulator from the upper part, and only the liquid flows into the evaporator through the lower exhaust pipe.

[0003] The production process of the liquid storage tank requires the use of steel pipes of a certain length. These required steel pipes need to be purchased and cut into the required length according to the requirements. After the steel pipes are cut, a swingable receiving plate is generally used to slide the cut steel pipes into the collecting box. However, when the steel pipes are cut continuously, after one steel pipe falls, the next steel pipe falls immediately afterwards. During the falling process, the two connected steel pipes will collide. Due to the high temperature generated by laser cutting, the cut part of the steel pipe is relatively soft. When the two steel pipes collide, it is easy to cause a dent in the cut part, thereby affecting the production quality of the entire steel pipe. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative inspiration are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1-Figure 8 The laser cutting device for a liquid storage steel pipe shown in the figure comprises a device base 1 and a slide 2 fixedly mounted on the top of the device base 1, a long tube 3 is arranged on the top of the slide 2, two movable clamps 4 slidably mounted on the top of the slide 2 are arranged on the outside of the long tube 3 for conveying the long tube 3, a bracket 5 is fixedly mounted on the right side of the slide 2, a laser cutter 6 located just above the long tube 3 is fixedly mounted on the outside of the bracket 5 for cutting the long tube 3, and a laser cutter 6 located just above the long tube 3 is rotatably mounted on the inside of the bracket 5 There is a feeding table 7 directly below the tube 3, and a feeding box 8 is fixedly installed on the outer side of the slide 2. The feeding table 7 is tilted and rotated to pour the cut steel pipes into the feeding box 8; it also includes: a feeding mechanism, which is used to feed the steel pipes cut by the laser cutter 6 at intervals, and the feeding mechanism is installed inside the feeding box 8; a blocking mechanism, which is used to provide buffering for the steel pipes entering the feeding box 8, and the blocking mechanism is installed on the top of the feeding box 8; a discharging mechanism, which is used to guide the steel pipes in the feeding box 8 to be discharged, and the discharging mechanism is installed at the bottom of the feeding box 8.

[0031] The unloading mechanism includes two conveyor belts 9 symmetrically arranged inside the unloading box 8. The top of the conveyor belt 9 is an inclined structure. The cut steel pipe can be pushed downward along the inclined surface of the conveyor belt 9. Transmission rollers 10 are rotatably installed at both ends of the conveyor belt 9. A motor 11 is fixedly installed on the right side of the unloading box 8. The output end of the motor 11 is fixedly connected to the adjacent transmission roller 10. A gear 12 is fixedly installed at one end of the transmission roller 10 at the bottom of the conveyor belt 9. The two gears 12 cooperate with each other. When the motor 11 is running, it can The corresponding transmission roller 10 drives the two gears 12 to rotate, so that the two conveyor belts 9 can move synchronously in opposite directions. The distance between the two conveyor belts 9 is the same as the outer diameter of the long tube 3. The outer side of the conveyor belt 9 is fixedly connected with a plurality of equally spaced material receiving ribs 13. The outer side of the material receiving ribs 13 is an inclined structure, which is convenient for receiving the steel pipe. The inner side of the conveyor belt 9 is provided with a positioning bar 14, which is fixedly installed on the inner side of the unloading box 8. The outer side of the positioning bar 14 contacts the inner side of the conveyor belt 9 to provide support for the inner side of the conveyor belt 9.

[0032] When the motor 11 is running, the two gears 12 are driven to rotate in opposite directions through the corresponding transmission rollers 10, so that the gears 12 drive the corresponding transmission rollers 10 to rotate, so that the two conveyor belts 9 can achieve the effect of synchronous and opposite rotation. The steel pipes cut by the laser cutter 6 for the long tube 3 can fall on the conveyor belt 9 through the unloading platform 7. The two conveyor belts 9 clamp and position the steel pipes, and push the steel pipes downward through the splicing ribs 13 so that the steel pipes are between the two conveyor belts 9, and the mobile clamp 4 pushes the long tube 3 so that the laser cutter 6 cuts the long tube 3 again. The next steel pipe enters between the two conveyor belts 9. Under the separation of the splicing ribs 13, a certain distance is maintained between each steel pipe, so that collision-free transportation of multiple steel pipes is achieved, thereby achieving the effect of safe unloading.

[0033] The material blocking mechanism includes a blocking bar 15 arranged at the top opening of the material box 8, which is used to resist the outer side of the long tube 3. The outer side of the material box 8 is provided with a long groove for the blocking bar 15 to limit the sliding of the blocking bar 15. Both ends of the blocking bar 15 are fixedly connected with push rods 16. The outer side of the material box 8 is fixedly connected with a U-shaped frame 17 for limiting the sliding of two push rods 16 to provide a guide for the movement of the push rods 16. The U-shaped frame 17 and the outer side of the push rods 16 are fixedly connected with a support plate 18. A spring 19 is fixedly installed between the two support plates 18 to facilitate the reset of the push rods 16. A spring 19 is fixedly installed below the push rods 16. The turntable 20 is rotatably mounted on the outside of the material box 8. A convex strip 21 is fixedly connected to the outside of the turntable 20. Both sides of the convex strip 21 are inclined structures. The end of the push rod 16 away from the baffle 15 is rotatably mounted with a positioning wheel 22 in contact with the outside of the turntable 20. When the inclined surface of the convex strip 21 moves along the outside of the positioning wheel 22, it can push the push rod 16 to move upward. A synchronous belt 23 is rotatably mounted on the axis of the turntable 20. The other end of the synchronous belt 23 is rotatably mounted with the adjacent transmission roller 10, so that when the transmission roller 10 rotates, the turntable 20 is driven to rotate;

[0034] When the steel pipe enters the blanking box 8, the steel pipe contacts the outer side of the baffle 15 and the outer side of the conveyor belt 9. The rotation of the conveyor belt 9 is used to keep the steel pipe parallel to the baffle 15. At the same time, the driving roller 10 drives the turntable 20 to rotate through the synchronous belt 23, and the turntable 20 drives the convex strip 21 to rotate. When the inclined surface on one side of the convex strip 21 contacts the positioning wheel 22 on the push rod 16, the inclined surface of the convex strip 21 pushes the positioning wheel 22 to move, so that the positioning wheel 22 drives the push rod 16 to move along the inner side of the U-shaped frame 17, and compresses the spring 19 through the support plate 18 and drives the baffle 15 away from the steel pipe. The material connection rib 13 can push the steel pipe between the two conveyor belts 9 to carry out blanking and conveying of the steel pipe, which is convenient for correcting the steel pipe and preventing the steel pipe from tilting. When the convex strip 21 is away from the positioning wheel 22, the rebound force of the spring 19 is used to reset the push rod 16, thereby achieving the effect of smooth blanking.

[0035] The discharging mechanism includes a receiving box 24 fixedly mounted at the bottom of the unloading box 8, which is used to catch the falling steel pipe. A plurality of rotating rods 25 with inclined and equidistant distribution are rotatably mounted on the inner side of the receiving box 24. Both ends of the rotating rod 25 extend to the outside of the receiving box 24. A rotating drum 26 is fixedly connected to the outside of the rotating rod 25. The distance between adjacent rotating drums 26 is less than the outer diameter of the long tube 3, which is convenient for catching the cut steel pipe. Toothed belts 27 located on the outside of the rotating rod 25 are arranged on both sides of the receiving box 24. The rotating rod 25 is provided with a toothed belt 27. Both ends are fixedly connected with gears 28 matched with toothed belts 27. A discharge port is provided on the outer side of the material receiving box 24. A discharge plate 29 is fixedly installed on the inner side of the discharge port. The discharge plate 29 is an inclined structure and has the same inclination angle as the plurality of rotating rods 25. Both sides of the material receiving box 24 are provided with synchronous belts 230. The two ends of the synchronous belts 230 are rotatably installed with the adjacent rotating rods 25 and the transmission rollers 10, respectively. When the transmission rollers 10 rotate, the plurality of gears 28 can be driven to rotate synchronously through the synchronous belts 230.

[0036] When the conveyor belt 9 pushes the steel pipe into the receiving box 24, the steel pipe falls between the two rotating drums 26, and the driving roller 10 drives the corresponding rotating rod 25 to rotate through the synchronous belt 2 30, so that the rotating rod 25 drives the synchronous belt 2 30 to rotate through the corresponding gear 2 28, and the synchronous belt 2 30 drives the remaining gears 28 to rotate synchronously and in the same direction, thereby achieving the effect of synchronous rotation of multiple rotating rods 25, and utilizing the intervals and rotation between the rotating drums 26 to push the fallen cutting scraps into the bottom inner wall of the receiving box 24, and the rotating drum 26 pushes the steel pipe to move obliquely to the discharge plate 29, so that it can be discharged from the discharge port on the outside of the receiving box 24, thereby achieving the effect of smooth discharge and cleaning of scraps.

[0037] Working principle: First, the user installs the long tube 3 between the two mobile clamps 4, so that the mobile clamp 4 pushes one end of the long tube 3 to the bottom of the laser cutter 6. The laser cutter 6 cuts the long tube 3, and the cut steel tube and scraps fall on the unloading platform 7. The unloading platform 7 swings downward to push the steel tube and scraps into the unloading box 8, so that the steel tube contacts the top of the baffle 15 and the conveyor belt 9. At this time, the motor 11 runs, and the motor 11 drives the transmission roller 10 installed thereon to rotate, so that the transmission roller 10 drives another gear 12 through the corresponding gear 1. 12 rotates in the opposite direction, and the gear 12 drives the corresponding transmission roller 10 to rotate, so that the two conveyor belts 9 rotate synchronously and in the opposite direction. The conveyor belt 9 pushes the steel pipe to keep parallel with the baffle 15. At the same time, the transmission roller 10 drives the turntable 20 to rotate through the synchronous belt 23, and the turntable 20 drives the convex strip 21 to rotate, so that the inclined surface on one side of the convex strip 21 contacts the positioning wheel 22 on the push rod 16, and the inclined surface of the convex strip 21 pushes the positioning wheel 22 to move, so that the positioning wheel 22 drives the push rod 16 to move along the inner side of the U-shaped frame 17, driving the baffle 15 away from the steel pipe, and the material splicing ribs on the conveyor belt 9 The strip 13 pushes the steel pipe between the two conveyor belts 9, and pushes the steel pipe downward so that the steel pipe is between the two conveyor belts 9. The outer sides of the two conveyor belts 9 clamp and convey the steel pipe downward. At this time, the mobile clamp 4 pushes the long pipe 3, so that the laser cutter 6 cuts the long pipe 3 again. The next steel pipe enters between the two conveyor belts 9. Under the separation of the splicing rib 13, each steel pipe has a certain distance between them, so that collision-free conveying of multiple steel pipes is realized. Finally, the conveyor belt 9 pushes the steel pipe into the splicing box 24, and the steel pipe falls between the two rotating drums 26. The driving roller 10 drives the corresponding rotating rod 25 to rotate through the synchronous belt 2 30, so that the rotating rod 25 drives the synchronous belt 2 30 to rotate through the corresponding gear 2 28, and the synchronous belt 2 30 drives the remaining gears 28 to rotate synchronously and in the same direction, so that multiple rotating drums 26 rotate synchronously, pushing the steel pipe to move obliquely to the discharge plate 29, and then it can be discharged from the discharge port outside the receiving box 24. The interval and rotation between the rotating drums 26 are used to push the fallen cutting scraps into the bottom inner wall of the receiving box 24, thereby achieving a smooth and uniform feeding effect and improving the production quality of the steel pipe.

[0038] Example 2: Please refer to Figure 2-Figure 6The present embodiment further explains the first embodiment. The length of the material splicing rib 13 shown in the figure is less than the length of the conveyor belt 9, which is convenient for the falling of the scraps generated during cutting. Positioning frames 31 are provided at both ends of the conveyor belt 9. The positioning frame 31 is fixedly installed on the inner side of the blanking box 8. The inner side of the positioning frame 31 contacts the outer side of the conveyor belt 9 to improve the stability of the rotation of the conveyor belt 9. The outer side of the baffle 15 is fixedly connected with a rubber sleeve 32 to provide a buffer for the movement of the steel pipe. The top of the support plate 18 on the push rod 16 is fixedly connected with a sliding rod 33. The sliding rod 33 slides through the support plate 18 on the U-shaped frame 17 to improve the stability of the movement of the push rod 16.

[0039] In this embodiment: the scraps generated when the laser cutter 6 cuts the long tube 3 can fall downward through the material splicing ribs 13, and the material splicing ribs 13 can position the steel tube, which is convenient for screening the scraps and the steel tube. The positioning frame 31 can provide positioning support for the rotation of the conveyor belt 9, which is convenient for the top end of the conveyor belt 9 to remain tilted, and when the steel tube is close to the baffle 15, the rubber sleeve 32 can provide buffering and protection for the steel tube. When the push rod 16 moves, it can drive the sliding rod 33 to move along the inner side of the support plate 18 on the U-shaped frame 17, keeping the push rod 16 stable in resetting upward and downward.

[0040] Example 3: Please refer to Figure 7 and Figure 8 This embodiment further explains other embodiments. The bottom inner wall of the material receiving box 24 shown in the figure is provided with a slag storage box 34. The outer side of the slag storage box 34 is in contact with the inner side of the material receiving box 24 for storing scraps. The right side of the material receiving box 24 is provided with a limiting sliding opening for the slag storage box 34. The outer side of the slag storage box 34 is fixedly connected with a handle 35 to facilitate pulling the slag storage box 34 out of the material receiving box 24.

[0041] In this embodiment, the fallen scraps can pass through the material receiving box 24 and enter the slag storage box 34. When cleaning later, the user can pull the handle 35 to take the slag storage box 34 out of the material receiving box 24 to clean the scraps.
