Technical Field

[0001] The utility model relates to the technical field of automatic sandblasting for metal materials, and specifically relates to an automatic sandblasting device for metal materials. Background Technique

[0002] An automatic sandblasting device is an automatic equipment used for sandblasting the surface of workpieces. The automatic sandblasting device can improve work efficiency, ensure the consistency of sandblasting quality, be applicable to a variety of workpieces, and is widely used in industries such as metal processing, automobile manufacturing, aerospace, and shipbuilding for removing rust, scale, and old coatings on the surface of workpieces, and can also be used for surface strengthening and decorative treatment;

[0003] The applicant found through retrieval that the Chinese patent disclosed an "automatic sandblasting device for aluminum tube production", and its publication (announcement) number is "CN211967159U". This patent mainly reduces the difficulty of subsequent cleaning of aluminum tubes by setting up a cleaning component to clean the sand and water on the aluminum tubes, reduces the waste of sand and water, and saves costs. However, when the sand material in the existing automatic sandblasting device is static in the sand bucket for a long time and the environment is humid, the internal sand material is prone to caking, which in turn causes blockage in sandblasting and affects the sandblasting quality. For this reason, we propose an automatic sandblasting device for metal materials. Content of the Utility Model

[0026] In an embodiment of the utility model: the heating groove 502 is opened inside the sand bucket 501. The outer wall of the heating cable 503 is clamped inside the heating groove 502. The bottom of the limit buckle 504 is inserted into the heating groove 502. Both ends of the heating cable 503 are located outside the sand bucket 501, and the temperature controllers 505 are fixedly installed on the front surface of the sand bucket 501.

[0027] In an embodiment of the utility model: the sealing cover plate 506 is arranged on the upper surface of the sand bucket 501. The sand inlet pipe 507 is fixedly installed at a position close to the left side on the upper surface of the sealing cover plate 506, and the motor 508 is fixedly installed at a position close to the right side on the upper surface of the sealing cover plate 506.

[0028] In an embodiment of the utility model: the driving gear disc 509 is fixedly installed at the lower end of the motor 508. The driven gear disc 510 is fixedly installed at a position close to the upper end on the outer wall of the rotating frame 511. The driving gear disc 509 and the driven gear disc 510 are meshed with each other. The rotating frame 511 is rotatably connected with the sealing cover plate 506, and the stirring member 512 is fixedly installed at a position close to the lower end on the outer wall of the rotating frame 511.

[0029] In an embodiment of the utility model: a recycling mechanism 6 is arranged below the frame 1. The recycling mechanism 6 includes a material receiving channel 61. The upper end of the material receiving channel 61 is fixedly installed at the lower end of the frame 1. The upper end of the material receiving channel 61 coincides with the lower end of the leakage plate 4. Slide grooves 62 are respectively opened at positions close to the lower end on the inner side surface of the material receiving channel 61. A material receiving box 63 is slidably connected inside the slide grooves 62.

[0030] In one embodiment of the present utility model: a rotating hole 64 is opened on the inner walls of both sides of the material receiving box 63 near the middle position of the upper end, and a sieve plate 67 is rotatably connected inside the rotating hole 64. Limiting members 65 are fixedly installed at the four corners of the inner wall of the material receiving box 63 near the upper end, and springs 66 are fixedly installed on the upper and lower inner walls of the limiting members 65. The four corners of the sieve plate 67 are located between the two groups of springs 66.

[0031] Example 1, please refer to the attached Figure 1 -Attached Figure 3 A wire groove adapted to the heating cable 503 is opened on the inner wall of the heating groove 502. The heating groove 502 is coiled in the heating cable 503 and is inserted into the heating groove 502 through a limiting buckle 504, so that the heating cable 503 is fixed inside the heating cable 503.

[0032] Example 2, please refer to the attached Figure 1 -Attached Figure 5 The sand material that comes into contact with the metal material in the frame 1 is prone to carry dust. A dust filter that can absorb dust is provided inside the screen plate 67. The dust can be absorbed while screening the sand material, thereby improving the recovery rate of the sand material.

[0033] Specifically, the temperature value of the thermostat 505 is adjusted to control the heat dissipation temperature of the heating cable 503, and then the heating tank 502 of the sand bucket 501 is heated to heat the sand inside the sand bucket 501. At the same time, the motor 508 is turned on to rotate the driving gear plate 509, and then the driven gear plate 510 is rotated, driving the stirring member 512 on the rotating frame 511 to stir the sand in the sand bucket 501, so as to prevent the sand inside the sand bucket 501 from being agglomerated due to being left still for a long time, thereby avoiding the problem of uneven sandblasting caused by clogging of the nozzle 2, and improving the quality and efficiency of sandblasting of metal materials.

[0034] Specifically, excess sand material during sandblasting in the frame 1 falls into the material collecting channel 61. The sand material falls on different positions of the sieve plate 67, causing the sieve plate 67 to swing left and right with the rotating hole 64 as the midpoint, thereby screening the sand material. The sieve plate 67 is kept swinging by two sets of springs 66, and the collected sand material falls into the material collecting box 63, which can be pulled out for replacement when it is full, thereby improving the utilization rate of the sand material.

[0035] Working principle:

[0036] First, adjust the temperature value of the thermostat 505 to control the heat dissipation temperature of the heating cable 503, and then heat the heating groove 502 of the sand bucket 501 to heat the sand inside the sand bucket 501, and at the same time turn on the motor 508 to rotate the active gear plate 509, and then rotate the driven gear plate 510, driving the stirring member 512 on the rotating frame 511 to stir the sand in the sand bucket 501 to prevent the sand inside the sand bucket 501 from being agglomerated due to long-term static state, thereby avoiding the problem of uneven sandblasting caused by blockage of the nozzle 2. After sandblasting the metal material, the excess sand will fall into the material receiving channel 61 along the leak plate 4. The sand falls on different positions of the sieve plate 67, causing the sieve plate 67 to swing left and right with the rotating hole 64 as the midpoint, and the sand is sieved. The sieve plate 67 is kept swinging by two sets of springs 66. The collected sand falls into the material receiving box 63, which can be pulled out for replacement after being filled. At this point, the entire workflow ends.
