Description

Technical Field

[0001] The utility model relates to the technical field of ship painting, in particular to a ship painting sandblasting machine which can reduce dust. Background Art

[0002] Before repairing the paint on the ship workpiece, it is necessary to spray sand, copper ore and other abrasives on the workpiece surface to remove the rust on the workpiece surface and obtain a certain degree of cleanliness. When sandblasting a ship, a sandblasting machine is usually required to clean and roughen the surface of the substrate by utilizing the impact of high-speed sand flow. Compressed air is used as the power to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, Hainan sand) at high speed onto the surface of the workpiece to be processed, so that the appearance or shape of the outer surface of the workpiece surface changes.

[0003] A ship coating sandblasting machine disclosed in Chinese patent CN115570512A includes a sandblasting pot, a support frame, a high-pressure air supply box, a sandblasting tube, a high-pressure water supply box, and a sandblasting head. The sandblasting pot is arranged on the support frame, the high-pressure air supply box is arranged on one side wall of the sandblasting pot, and the high-pressure water supply box is arranged on the other side wall of the sandblasting pot; a sand outlet pipe is arranged at the lower end of the sandblasting pot, the sandblasting tube is arranged horizontally at the lower end of the sand outlet pipe, and the middle part of the sandblasting pot is connected with the sand outlet pipe; an air duct is arranged at the lower end of the high-pressure air supply box.

DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] See also Figures 1 to 7 As shown, a ship painting sandblasting machine capable of reducing dust comprises a sandblasting pot 1, a supporting foot 2 is arranged at the bottom of the sandblasting pot 1, a feed port 11 and a discharge port 12 are respectively opened on the sandblasting pot 1, a sandblasting mechanism 3 is arranged on one side of the sandblasting pot 1, an input end of the sandblasting mechanism 3 is connected with the discharge port 12 of the sandblasting pot 1 through a high-pressure air pipe 5, and the high-pressure air pipe 5 is connected to an external high-pressure air pump, and a dustproof mechanism 4 is arranged at the output end of the sandblasting mechanism 3.

[0025] When the device is used, the abrasive is first transported from the feed port 11 of the sandblasting pot 1 to the sandblasting pot 1, and high-pressure gas is generated through the cooperation of the high-pressure air pipe 5 and the external high-pressure air pump, and then the abrasive in the sandblasting pot 1 is transported from the discharge port 12 to the sandblasting mechanism 3, and then the abrasive is sprayed onto the surface of the ship through the sandblasting mechanism 3, and then the surface of the ship is polished. By setting the dustproof mechanism 4 installed at the output end of the sandblasting mechanism 3, a closed working space is formed at the output end of the sandblasting mechanism 3 during the polishing of the ship surface, so as to prevent a large amount of dust generated when the abrasive collides with the ship surface from diffusing into the air, thereby affecting the ring around the work, and at the same time, it can also prevent the sprayed abrasive from rebounding onto the staff after colliding with the ship surface.

[0026] See also Figure 1 and Figure 2 As shown, the sandblasting mechanism 3 includes an air-controlled valve 31, a sand outlet pipe 32 and a sandblasting gun head 33. The air-controlled valve 31 is arranged on the high-pressure air pipe 5, one end of the sand outlet pipe 32 is connected to the output end of the air-controlled valve 31, and the sandblasting gun head 33 is arranged at the end of the sand outlet pipe 32 away from the air-controlled valve 31.

[0027] Through the cooperation of the sand outlet pipe 32 and the sandblasting gun head 33, the abrasive in the sandblasting tank 1 can be sprayed onto the surface of the ship, thereby grinding the surface of the ship. Through the setting of the air control valve 31, the air flow intensity in the high-pressure air pipe 5 can be controlled, and the spraying intensity of the sandblasting gun head 33 can be controlled according to the grinding requirements of the ship surface.

[0028] See also Figure 3 As shown, the dustproof mechanism 4 includes a dustproof cover 41, a movable component 42 and a magnetic component 43. One end of the dustproof cover 41 is sleeved on the output end of the sandblasting mechanism 3, the magnetic component 43 is arranged at an end of the dustproof cover 41 away from the sandblasting mechanism 3, and the movable component 42 has multiple components respectively arranged on the dustproof cover 41.

[0029] When the sandblasting mechanism 3 is used, first, one end of the dust cover 41 on the sandblasting mechanism 3 is placed against the surface of the ship. The dust cover 41 is tightly fitted to the surface of the ship through the setting of the magnetic suction component 43. The dust cover 41 forms a closed working space between the sandblasting mechanism 3 and the surface of the ship, so that when the sandblasting mechanism 3 sandblasts and polishes the surface of the ship, a large amount of dust generated will not be dispersed into the outside air, thereby avoiding the pollution of the outside air. At the same time, it also avoids the staff from inhaling dust-containing gases in the air into their bodies during the sandblasting process, thereby having a certain protective effect on the staff's body. After the area of ​​the ship's surface covered by the dust cover 41 is polished, through the cooperation of multiple moving components 42, the staff can easily drive the dust cover 41 to move to the next polishing area on the ship's surface, and it will not affect the use of the magnetic suction component 43.

[0030] See also Figure 3 , Figure 5 and Figure 6 As shown, a plurality of mounting grooves 412 are provided on the outside of the dust cover 41, and the movable assembly 42 includes a mounting frame 421, a placement plate 422, a ball 423 and a buffer 424. The number of the mounting frames 421 is the same as the number of the mounting grooves 412 provided in the dust cover 41 and corresponds one to one. The mounting frames 421 are arranged in the corresponding mounting grooves 412, and the placement plate 422 is horizontally arranged below the mounting frame 421. A placement hole 4221 for placing the ball 423 is provided at the bottom of the placement plate 422, and the top of the placement plate 422 is movably connected to the mounting frame 421 through a buffer 424.

[0031] By cooperating with the mounting frame 421 and the mounting groove 412, the placement plate 422 is arranged outside the dust cover 41. The ball 423 arranged at the bottom of the placement plate 422 makes it easier to move the dust cover 41. The buffer 424 is arranged to reduce shock during the movement of the dust cover 41.

[0032] See also Figure 6 and Figure 7 As shown, the buffer member 424 includes a limiting column 4241, a buffer spring 4242 and a baffle 4243. The limiting column 4241 is arranged on the top of the placement plate 422, and one end of the limiting column 4241 away from the placement plate 422 passes upward through the mounting frame 421. The buffer spring 4242 is sleeved on the outside of the limiting column 4241, and the buffer spring 4242 is located between the mounting frame 421 and the placement plate 422. The baffle 4243 is arranged on one end of the limiting column 4241 passing through the mounting frame 421.

[0033] By setting the limiting column 4241, the placement plate 422 can move up and down on the mounting frame 421, so that the ball 423 on the placement plate 422 can move more smoothly on the surface of the ship. By setting the buffer spring 4242, the impact force generated by the collision between the ball 423 and the protruding particles on the surface of the ship can be reduced, thereby increasing the service life of the ball 423. By setting the baffle 4243, the limiting column 4241 on the top of the placement plate 422 is prevented from detaching from the mounting frame 421.

[0034] See also Figure 3 and Figure 5 As shown, the magnetic attraction assembly 43 includes a magnetic attraction ring 431 and a screw 432 . The magnetic attraction ring 431 is arranged on one end of the dust cover 41 that is in contact with the surface of the ship. The magnetic attraction ring 431 is fixed to the dust cover 41 by the screw 432 .

[0035] The magnetic ring 431 is fixed to the dust cover 41 by means of screws 432. Through the setting of the magnetic ring 431, the dust cover 41 can be temporarily adsorbed on the surface of the ship, so that the dust cover 41 and the surface of the ship fit more closely, avoiding the dust in the dust cover 41 from leaking out from the fitting point between the dust cover 41 and the surface of the ship, thereby improving the dustproof effect of the dust cover 41.

[0036] See also Figure 5 As shown, the magnetic attraction strength of the magnetic ring 431 is a constant value.

[0037] By setting the magnetic attraction strength of the magnetic attraction ring 431, it is convenient for the staff to separate the magnetic attraction ring 431 from the surface of the ship with one hand.

[0038] See also Figure 4 As shown, a collecting port 411 is provided on the dust cover 41 , and a collecting pipe 44 is connected to the collecting port 411 , and the collecting pipe 44 is connected to an external vacuum cleaner.

[0039] By opening a collecting port 411 on the dust cover 41, it is convenient to connect the collecting pipe 44 connected to an external vacuum cleaner. Through the cooperation of the collecting pipe 44 and the external vacuum cleaner, the dust mixed with abrasives in the dust cover 41 can be collected to facilitate the subsequent recycling of the abrasives.

[0040] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
