Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel bar cleaning technology, and in particular relates to a shot blasting machine for cleaning the surface of steel bars. Background Technology
[0002] A shot blasting machine is a device that propels steel shot to the surface of reinforcing bars at high speed and with high density. Its core purpose is to efficiently and thoroughly remove impurities such as oxide scale, rust, welding slag, and oil stains from the surface of reinforcing bars, exposing the uniform metallic color of the reinforcing bars and forming a certain roughness on the surface.
[0003] Chinese patent CN204076034U discloses a shot blasting machine for cleaning the surface of reinforcing bars, including a shot blasting container with a shot blaster at the top for blasting shot into the container. Below the shot blaster is an inclined tray for holding reinforcing bars. The lower end of the tray is hinged to a column, and the bottom of the tray rests on at least one swing cam. The swing cam is connected to the output shaft of a motor through a transmission component. The output shaft of the motor also drives a translational cam through another transmission component. The translational cam contacts the inner wall of the container.
[0004] As shown above, the device drives the pallet to move by rotating the swing cam and the translation cam synchronously, thereby moving the steel bars placed inside the pallet so that the steel bars can be hit by the shot blaster from all directions. However, if the swing cam and the translation cam rotate too fast, the steel bars may fall off the pallet. If the speed is too slow, the steel bars may not be hit evenly. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a shot blasting machine for cleaning the surface of reinforcing bars, which solves the problem of uneven shot blasting coverage when cleaning the surface of reinforcing bars.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a shot blasting machine for cleaning the surface of reinforcing bars, comprising a shot blasting shell, a detachable cover plate provided on the top of the shot blasting shell, a shot blasting mechanism provided inside the shot blasting shell, and a collecting mechanism provided at the bottom of the shot blasting shell; The shot blasting mechanism includes several shot blasters fixedly connected to the outer wall of the shot blasting shell. A motor is fixedly connected to the outer wall of the shot blasting shell. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. A first disc is fixedly connected to the outer wall of the rotating shaft. Several rotating rods are rotatably connected to the inner wall of the first disc. A first extrusion block is fixedly connected to the outer wall of each rotating rod. A gear is fixedly connected to the side of each rotating rod away from the first extrusion block. A second disc is fixedly connected to the outer wall of the rotating shaft. Several lead screws are threadedly connected to the inner wall of the second disc. A knob is fixedly connected to the outer wall of each lead screw. A second extrusion block is rotatably connected to the side of each lead screw away from the knob. Limiting components are provided on the several lead screws. An internal gear is fixedly connected to the outer wall of the shot blasting shell.
[0007] Preferably, the limiting component includes several fixed plates fixedly connected to the outer wall of the second disc, two sliding shafts slidably connected to the inner wall of the fixed plates, a first locking block fixedly connected to the top of each of the two sliding shafts, two first springs fixedly connected to the side of the first locking block near the sliding shaft, and a connecting block fixedly connected to the bottom of each of the two sliding shafts.
[0008] Preferably, the inner wall of the internal gear meshes with the outer walls of several gears, the side of the two first springs away from the first locking block is fixedly connected to the outer wall of the fixing plate, and the two sliding shafts are respectively located inside the two first springs.
[0009] Preferably, the collecting mechanism includes a channel fixedly connected to the bottom of the shot blasting shell, a fan fixedly connected to the outer wall of the channel for blowing air into the channel, a first collecting shell provided at the bottom of the channel for collecting shot, a shell fixedly connected to the outer wall of the channel, a second locking block slidably connected to the inner wall of the shell, and two limiting blocks locking the outer wall of the second locking block.
[0010] Preferably, a second collection housing is fixedly connected to the bottom of the two limiting blocks for collecting impurities. A fixing block is fixedly connected to the outer wall of the housing, and a telescopic rod is fixedly connected to the side of the fixing block near the housing.
[0011] Preferably, the side of the telescopic rod away from the fixed block is fixedly connected to the outer wall of the second locking block, and a second spring is fixedly connected to the side of the fixed block near the telescopic rod. The end of the second spring away from the fixed block is fixedly connected to the outer wall of the second locking block, and the telescopic rod is located inside the second spring.
[0012] This utility model has the following beneficial effects: 1. This shot blasting machine for cleaning the surface of reinforcing bars moves the sliding shaft by pulling down the connecting block, causing the first clamping block to squeeze the first spring and disengage from the knob. Then, the reinforcing bar is placed between the first and second clamping blocks. The knob is manually turned to rotate the screw and push the second clamping block, thus working together with the first clamping block to clamp and fix the reinforcing bar. After the connecting block is released, the rebound force of the first spring pushes the first clamping block to reset and lock the knob, effectively preventing it from loosening. After the motor is started, the rotating shaft drives the first and second discs to revolve, forcing the clamped reinforcing bar to perform circular motion. At the same time, the gear fixed on the rotating rod meshes with the fixed internal gear during the revolution, generating a rotational motion, which allows the reinforcing bar to obtain a uniform shot blasting cleaning effect in all directions during the movement.
[0013] 2. The shot blasting machine for cleaning the surface of the reinforcing bars uses a blower to generate controllable air force, which is sufficient to blow light impurities into the second collection shell, while heavy shot falls directly into the first collection shell. By manually squeezing the second locking block, it compresses the second spring and pushes the telescopic rod to move, thereby breaking free from the limiting block. The second collection shell can then be easily moved out for cleaning, which can effectively improve the purity of the recovered shot and facilitate subsequent processing of impurities.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides two technical solutions: Figures 1-4 The first embodiment of a shot blasting machine for cleaning the surface of reinforcing bars is shown: A shot blasting machine for cleaning the surface of reinforcing bars includes a shot blasting shell 1, a detachable cover plate 101 is provided on the top of the shot blasting shell 1, a shot blasting mechanism 2 is provided inside the shot blasting shell 1, and a collecting mechanism 3 is provided at the bottom of the shot blasting shell 1. The shot blasting mechanism 2 includes several shot blasters 201 fixedly connected to the outer wall of the shot blasting housing 1. A motor 202 is fixedly connected to the outer wall of the shot blasting housing 1. The output shaft of the motor 202 is fixedly connected to a rotating shaft 203 via a coupling. A first disc 204 is fixedly connected to the outer wall of the rotating shaft 203. Several rotating rods 205 are rotatably connected to the inner wall of the first disc 204. A first extrusion block 206 is fixedly connected to the outer wall of the rotating rods 205. The side of the rotating rod 205 away from the first extrusion block 206 is fixed. A gear 207 is connected, and a second disc 208 is fixedly connected to the outer wall of the rotating shaft 203. Several lead screws 209 are threadedly connected to the inner wall of the second disc 208. A knob 210 is fixedly connected to the outer wall of the lead screw 209. A second extrusion block 217 is rotatably connected to the side of the lead screw 209 away from the knob 210. Limiting components are provided on the several lead screws 209. An internal gear 216 is fixedly connected to the outer wall of the shot blasting shell 1. The inner wall of the internal gear 216 meshes with the outer wall of the several gears 207.
[0020] The limiting assembly includes several fixed plates 211 fixedly connected to the outer wall of the second disc 208. Two sliding shafts 212 are slidably connected to the inner wall of the fixed plates 211. A first locking block 213 is fixedly connected to the top of each of the two sliding shafts 212. Two first springs 214 are fixedly connected to the side of the first locking block 213 near the sliding shaft 212. The side of the two first springs 214 away from the first locking block 213 is fixedly connected to the outer wall of the fixed plate 211. The two sliding shafts 212 are located inside the two first springs 214 respectively. A connecting block 215 is fixedly connected to the bottom of each of the two sliding shafts 212.
[0021] First, pull down the connecting block 215 to move the sliding shaft 212. As the sliding shaft 212 moves, it also moves the first locking block 213, thus compressing the first spring 214 and moving the first locking block 213 away from the knob 210. Then, the rebar is placed between the first pressing block 206 and the second pressing block 217. Next, manually turn the knob 210 to rotate the lead screw 209. As the lead screw 209 rotates, it moves itself, causing the second pressing block 217 to come closer to the rebar, thus engaging with the first pressing block 206 to clamp and fix the rebar. Finally, release the connecting block. 215. At this point, due to the reaction force of the first locking block 213, the first locking block 213 will be squeezed, thus bringing it close to the knob 210 and fixing the rotation angle of the knob 210. Then, the motor 202 is started by the external controller, driving the rotating shaft 203 to rotate. As the rotating shaft 203 rotates, it will drive the first disc 204 and the second disc 208 to rotate together, thus causing the steel bar that is squeezed and fixed by the first pressing block 206 and the second pressing block 217 to rotate circumferentially. When the first disc 204 rotates, it will drive the gear 207 to rotate. During the circular movement of gear 207, due to the presence of internal gear 216, gear 207 not only rotates but also rotates on its own axis, thereby causing the clamped steel coil to rotate. At this time, the shot blaster 201 is activated by the external controller to blast the steel bar. This mechanism drives the sliding shaft 212 to move through the pull-down connecting block 215, causing the first locking block 213 to squeeze the first spring 214 and disengage from the knob 210. Subsequently, the steel bar is placed between the first pressing block 206 and the second pressing block 217. The knob 210 is manually turned to rotate the lead screw 209 and advance the second pressing block 217. This, together with the first extrusion block 206, completes the clamping and fixing of the reinforcing bar. After the connecting block 215 is released, the rebound force of the first spring 214 pushes the first locking block 213 to reset and lock the knob 210, effectively preventing it from loosening. After the motor 202 is started, the rotating shaft 203 drives the first disc 204 and the second disc 208 to revolve, forcing the clamped reinforcing bar to perform circumferential motion. At the same time, the gear 207 fixed on the rotating rod 205 meshes with the fixed internal gear 216 during the revolution, generating a rotational motion, which can make the reinforcing bar obtain a uniform shot blasting cleaning effect in all directions during the movement.
[0022] Figures 5-7The second embodiment is shown. The main difference between this embodiment and the first embodiment of the shot blasting machine for cleaning steel reinforcement surfaces is that the collecting mechanism 3 includes a channel 301 fixedly connected to the bottom of the shot blasting housing 1. A fan 302 is fixedly connected to the outer wall of the channel 301 for blowing air into the channel 301. A first collecting housing 303 is provided at the bottom of the channel 301 for collecting shot. A housing 304 is fixedly connected to the outer wall of the channel 301. A second locking block 305 is slidably connected to the inner wall of the housing 304. Two limiting blocks 306 are engaged on the outer wall of the second locking block 305. A second collection housing 307 is fixedly connected to the bottom of the 06 for collecting impurities. A fixing block 308 is fixedly connected to the outer wall of the housing 304. A telescopic rod 309 is fixedly connected to the side of the fixing block 308 near the housing 304. The side of the telescopic rod 309 away from the fixing block 308 is fixedly connected to the outer wall of the second locking block 305. A second spring 310 is fixedly connected to the side of the fixing block 308 near the telescopic rod 309. The end of the second spring 310 away from the fixing block 308 is fixedly connected to the outer wall of the second locking block 305. The telescopic rod 309 is located inside the second spring 310.
[0023] After the projectile clears the reinforcing steel, it passes through channel 301 along with impurities due to its own weight. At this time, the blower 302 is activated by the external controller to blow air into the channel 301. The airflow is insufficient to move the projectile, but sufficient to move the impurities, causing them to be blown into the second collection housing 307. The projectile then falls into the first collection housing 303 for collection. After the second collection housing 307 has finished collecting, the second locking block 305 is manually squeezed, causing it to move. As the second locking block 305 moves, it squeezes the telescopic rod 309 and the second spring 310. During this movement, the second locking block 305... The projectiles will gradually detach from the limiting block 306. At this point, the second collection housing 307 can be moved horizontally and removed. When the cleaned projectiles and impurities fall through the channel 301 due to gravity, the fan 302 generates controllable wind force. This wind force is sufficient to blow light impurities into the second collection housing 307, while heavy projectiles fall directly into the first collection housing 303. By manually squeezing the second locking block 305, it squeezes the second spring 310 and pushes the telescopic rod 309 to move, thereby detaching from the limiting block 306. The second collection housing 307 can then be easily moved horizontally and removed for cleaning, which can effectively improve the purity of the recovered projectiles and facilitate subsequent processing of impurities.
