Description

Technical Field

[0001] The utility model relates to the technical field of accessories of a rear device of an abrasive jetting machine, in particular to a frame shot blasting protective device. Background Art

[0002] The carbon steel frame of the color sorter will be shot blasted before spraying to remove rust and increase the adhesion of the plastic powder surface. However, the high-speed shot will enter the square tube of the frame through the threading holes. Once the shot enters the square tube, it is difficult to clean it out.

[0003] This requires adding protective devices to the wire threading holes of the frame to prevent the shielding pellets from entering the square tube of the frame. The existing technology uses a rubber shielding device, which needs to make a casting mold according to the specific size of the wire threading hole, and then pour high-temperature liquid rubber into the mold, and then form a rubber shielding device after the rubber cools and solidifies. One casting mold can only make one shielding device, and the size of the shielding device is fixed and not universal. There are many types of color sorters, and the sizes of the wire threading holes are different. It is necessary to make a variety of shielding devices, which requires the production of a variety of casting molds. The mold opening fee is high, and the cost of the entire rubber shielding device is correspondingly too high.

[0004] After searching, the patent with authorization announcement number: CN204321876U and name "A protective device for shot blasting surface protection" discloses a technical effect of using magnets to adsorb on a carbon steel frame to achieve protection. The shortcomings of this patent are: First, the magnets are set on the bottom plate. If the magnets correspond to the holes in the frame, it is likely to cause the device to offset relative to the holes on the frame, resulting in relatively poor protection effect; Second, the bottom of the magnetic positioning plate is a plane, and dust will be generated during the shot blasting process. If the dust is between the magnetic positioning plate and the frame, it will affect the magnetic attraction effect. The bottom surface of the magnetic positioning plate needs to be cleaned before each use. Utility Model Content

[0005] In order to solve the technical problems existing in the background technology, the utility model proposes a frame shot blasting protection device.

[0006] The utility model proposes a frame shot blasting protection device, including an upper cover plate and a positioning plate installed on the upper cover plate, the positioning plate is provided with a magnet, a limiting groove is opened in the middle of the positioning plate, the magnet is provided with multiple groups, the multiple groups of magnets are arranged around the limiting groove, and the bottom surface of the magnet and the bottom surface of the positioning plate are in the same horizontal plane. During the installation project, the limiting groove corresponds to the hole on the frame, the magnet is adsorbed to the frame, thereby avoiding the magnet corresponding to the hole to be covered on the frame, thereby ensuring the adsorption of the magnet and the frame, thereby avoiding the displacement of the installation plate relative to the frame.

[0007] Preferably, a mounting groove is formed on the positioning plate, and one of the magnets is connected to one of the mounting grooves.

[0008] In order to achieve the stability of the magnet fixation, the magnet is fixed to the upper cover plate by a fixing part. The fixing part can be a screw, a fixing pin or the like in the prior art that can fix two parts. That is, the magnet fixes the magnet and the positioning plate while also fixing the upper cover plate and the positioning plate.

[0009] Preferably, the side wall of the installation groove is coated with an adhesive layer, and the adhesive layer can be a glue layer in the prior art to achieve sticking the magnet in the installation groove.

[0010] In order to further prevent dust generated during shot blasting from accumulating on the bottom surfaces of the magnet and the positioning plate, an elastic ring is provided on the positioning plate and / or the upper cover plate, and the distance from the bottom surface of the elastic ring to the upper cover plate is greater than the distance from the bottom surface of the positioning plate to the upper cover plate.

[0011] Preferably, the magnet is enclosed in the elastic ring.

[0012] In order to achieve a better dust-proof effect, preferably, when the magnet is adsorbed on the frame, the elastic ring is in a compressed state.

[0013] Preferably, the elastic ring has a hollow cavity in the middle.

[0014] Preferably, a handle is provided on a side of the upper cover plate away from the positioning plate.

[0015] In the utility model, the proposed frame shot blasting protection device has a simple structure. The limit groove is set to correspond to the hole on the frame during the installation process, so as to avoid the magnet and the hole on the frame from corresponding to each other, thereby ensuring the adsorption of the magnet and the frame, and thus avoiding the displacement of the mounting plate relative to the frame; further, the magnet is connected to the positioning plate and fixed to the upper cover plate through the fixing member, so that the force between the upper cover plate and the positioning plate is reduced in the process of pulling the device, thereby ensuring the stability of the magnet installation; further, the elastic ring is set to avoid dust generated during the shot blasting process from entering the bottom surface of the magnet or the positioning plate, thereby increasing the work efficiency.
