Description

Technical Field

[0001] This utility model relates to the field of shot blasting machine technology, specifically a shot blasting machine with an anti-shaking structure. Background Technology

[0002] A shot blasting machine is a processing device that uses shot blasters to throw steel shot at high speed onto the surface of a material. Compared with other surface treatment technologies, it is faster and more efficient. Shot blasting machines are required for surface cleaning of small and medium-sized workpieces.

[0003] The existing Chinese utility model patent with publication number CN222026203U discloses a vibration-damping shot blasting machine, including a base with a groove inside. A vibration-damping plate is installed in the groove, and a piston block is installed inside a slide. A vibration-damping rod is welded to the piston block, and the vibration-damping rod passes through the top plate of the vibration-damping block and is fixedly connected to the bottom side of the vibration-damping plate. A spring is installed between the vibration-damping plate and the bottom wall of the groove. The machine body is welded to the top side of the vibration-damping plate. The machine body drives the vibration-damping plate to vibrate, and the spring between the vibration-damping plate and the bottom wall of the groove undergoes elastic deformation. The spring can absorb the stored energy of the impact force. Friction is generated between the side wall of the piston block and the inner wall of the slide, which consumes the kinetic energy of the spring, reducing the impact force and vibration. By installing the vibration-damping component, the shot blasting machine is damped, protected, and its vibration damping effect is improved, thus extending the service life of the shot blasting machine.

[0004] After prolonged use, the internal impeller of a shot blasting machine wears down, affecting its dynamic balance and causing vibration. The aforementioned vibration-damping shot blasting machine uses damping components to absorb some of the force generated by the vibration. However, the vibration generated by the shot blasting unit is still transmitted to the machine body, leading to loose or missing bolts, cracked welds, and machine body deformation. Furthermore, due to the limitation of the piston block, the damping plate can only move vertically and cannot absorb the force generated by the horizontal vibration of the shot blasting machine, resulting in limited damping effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a shot blasting machine with an anti-sway structure, which solves the problems that vibration still affects the machine body and that the horizontal shock absorption effect is limited.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A shot blasting machine with an anti-sway structure includes a base plate, and a shot blasting mechanism is arranged above the base plate.

[0007] A conveying assembly, positioned above the base plate, is used to convey the workpiece being processed.

[0008] A support component, positioned above the base plate, is used to support the drive component;

[0009] A drive assembly, positioned above the support assembly, is used to transport and eject steel shot.

[0010] The vibration damping component includes a base fixedly installed above a base plate, a connecting frame movably installed above the base, a connecting block fixedly installed above the connecting frame, a damping rod movably installed above the connecting block, a spring movably installed on the outer side of the damping rod, an adapter block movably installed at the upper end of the damping rod, and a limit block fixedly installed above the adapter block.

[0011] Preferably, the conveying assembly includes a shock-absorbing pad fixedly installed above the base plate, a support frame fixedly installed above the shock-absorbing pad, a conveying roller movably installed on the inner side of the support frame, toothed discs provided at both ends of the conveying roller, chains meshing at both ends of the conveying roller, and a conveying motor fixedly installed on one side of the support frame.

[0012] Preferably, the support assembly includes a housing fixedly installed above the shock-absorbing pad, rubber curtains fixedly installed on both sides of the housing, a canvas tube fixedly installed on the outer side of the housing, and a movable frame fixedly installed on the outer end of the canvas tube.

[0013] Preferably, the drive assembly includes a distributor fixedly installed above the housing, a conveying pipe fixedly installed below the distributor, a shot blaster fixedly installed at the bottom end of the conveying pipe, the shot blaster being fixed to the outside of the movable frame, and the shot blaster communicating with the inner cavity of the housing through a canvas pipe.

[0014] Preferably, the vibration-damping components are in four sets and are respectively installed on the front and rear sides of the base plate. The connecting frame and the base form a rotatable connection. The connecting blocks are mirror-symmetrically installed on the left and right ends of the connecting blocks with the center of the connecting frame as the reference.

[0015] Preferably, the bottom end of the damping rod is rotatably connected to the connecting block, and the top end of the damping rod is rotatably connected to the transition block. A disc-shaped protrusion is provided on the bottom end of the damping rod and the outer side of the movable end of the damping rod. The bottom end of the spring is fixedly connected to the protrusion structure at the bottom end of the damping rod, and the top end is fixedly connected to the protrusion structure on the outer side of the movable end of the damping rod. The limiting block and the transition block are rotatably connected, and the top end of the limiting block is fixedly connected to the bottom end of the movable frame.

[0016] Beneficial effects

[0017] This invention provides a shot blasting machine with an anti-sway structure. Compared with the prior art, it has the following advantages:

[0018] (1) The shot blasting machine with anti-shaking structure is equipped with a canvas tube. The canvas tube is fixedly installed on the outside of the shell and connects the shell and the movable frame. This makes it impossible for the vibration generated by the shot blaster fixed on the outside of the movable frame to be efficiently transmitted to the shell. At the same time, the damping pad above the bottom plate can play a shock absorption role on the support frame and the shell above. This method can avoid the formation of a soft connection between the main vibration source, the shot blaster, and the shell, and avoid the vibration affecting the structural strength of the shell.

[0019] (2) The shot blasting machine with anti-sway structure restricts the rotation axis and position of the damping rods on both sides by setting damping rods and connecting blocks at both ends of the connecting frame. The top of the damping rod is connected to the transition block, and the transition block is connected to the limiting block at the bottom of the movable frame. The initial angle between the base and the connecting frame, and between the transition block and the limiting block is 150 degrees. Since the base and the connecting frame are connected by rotation, when the vibration generated by the shot blaster is transmitted to the top of the movable frame, the angle between the base and the connecting frame, and between the transition block and the limiting block will change. The force generated by the vibration is absorbed by the contraction of the damping rod and converted into the internal energy of the damping rod. It is restored by the outer spring. This method enables the damping rod to reduce the vertical vibration while absorbing the force generated by the horizontal vibration, so as to improve the vibration resistance effect.

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.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a shot blasting machine with an anti-sway structure, including a base plate 1, and a shot blasting mechanism 2 arranged above the base plate 1.

[0027] The conveying assembly 21 is disposed above the base plate 1 for conveying the workpiece to be processed. The conveying assembly 21 includes a shock-absorbing pad 211 fixedly installed above the base plate 1, a support frame 212 fixedly installed above the shock-absorbing pad 211, a conveying roller 213 movably installed on the inner side of the support frame 212, a toothed disc provided at both ends of the conveying roller 213, a chain 214 meshing at both ends of the conveying roller 213, and a conveying motor 215 fixedly installed on one side of the support frame 212.

[0028] Specifically, the base plate 1 can limit the position of the conveying component 21, the shock-absorbing pad 211 can dampen the support frame 212 and the support component 22, the support frame 212 can limit the position of the conveying roller 213, the conveying roller 213 is linked by the toothed discs at both ends and the chain 214, the conveying motor 215 can drive one conveying roller 213 to rotate, and the remaining conveying rollers 213 are driven to rotate by the toothed discs at both ends of the conveying roller 213 to convey the workpiece.

[0029] The support assembly 22 is disposed above the base plate 1 to support the drive assembly 23. The support assembly 22 includes a housing 221 fixedly installed above the shock-absorbing pad 211. Rubber curtains 222 are fixedly installed on both sides of the housing 221. A canvas tube 223 is fixedly installed on the outer side of the housing 221. A movable frame 224 is fixedly installed on the outer end of the canvas tube 223.

[0030] Specifically, the outer shell 221 can support the drive assembly 23 and prevent steel shot from splashing after impacting the workpiece. The rubber curtain 222 can facilitate the workpiece to enter the interior of the outer shell 221 and block the steel shot. The canvas tube 223 can facilitate the formation of a soft connection between the outer shell 221 and the movable frame 224. The movable frame 224 can limit the position of the shot blaster 233.

[0031] The drive assembly 23 is located above the support assembly 22 and is used to transport steel shot and throw it out. The drive assembly 23 includes a diverter 231 fixedly installed above the housing 221. A conveying pipe 232 is fixedly installed below the diverter 231. A shot blaster 233 is fixedly installed at the bottom end of the conveying pipe 232. The shot blaster 233 is fixed to the outside of the movable frame 224 and is connected to the inner cavity of the housing 221 through the canvas pipe 223.

[0032] Specifically, the distributor 231 facilitates the entry of steel shot into each conveying pipe 232, and the steel shot is conveyed to the shot blaster 233 through the conveying pipe 232. The motor on one side of the shot blaster 233 can drive the internal impeller to rotate, and the impeller drives the steel shot to rotate, and the internal steel shot is thrown out by centrifugal force.

[0033] The vibration damping assembly 24 includes a base 241 fixedly installed above the base plate 1. A connecting frame 242 is movably installed above the base 241. A connecting block 243 is fixedly installed above the connecting frame 242. A damping rod 244 is movably installed above the connecting block 243. A spring 245 is movably installed on the outer side of the damping rod 244. A transition block 246 is movably installed at the upper end of the damping rod 244. A limit block 247 is fixedly installed above the transition block 246. The vibration damping assembly 24 has four sets installed on the front and rear sides of the base plate 1 respectively. The connecting frame 242 and the base 241 are rotatably connected. The connecting block 243 is connected to the connecting frame 241. The center of the damping rod 244 is mirror-symmetrically mounted on the left and right ends of the connecting block 243. The bottom end of the damping rod 244 is rotatably connected to the connecting block 243, and the top end of the damping rod 244 is rotatably connected to the adapter block 246. The bottom end of the damping rod 244 and the outer side of the movable end of the damping rod 244 are provided with a disc-shaped protrusion. The bottom end of the spring 245 is fixedly connected to the protrusion structure at the bottom end of the damping rod 244, and the top end is fixedly connected to the protrusion structure on the outer side of the movable end of the damping rod 244. The limiting block 247 is rotatably connected to the adapter block 246, and the top end of the limiting block 247 is fixedly connected to the bottom end of the movable frame 224.

[0034] Specifically, the base 241 can restrict the position of the connecting frame 242 and allow the connecting frame 242 to rotate in the left and right axial directions. The connecting blocks 243 at both ends of the connecting frame 242 restrict the rotation axis and position of the damping rods 244 on both sides. The top of the damping rod 244 is rotatably connected to the transition block 246. The transition block 246 is rotatably connected to the limiting block 247 at the bottom of the movable frame 224. The initial included angle between the base 241 and the connecting frame 242, and between the transition block 246 and the limiting block 247 is 150 degrees. The force generated by vibration is absorbed by the contraction of the damping rod 244, which is converted into the internal energy of the damping rod 244 and restored by the outer spring 245.

[0035] Specifically, the model of the conveyor motor 215 is YBK3, and the model of the damping rod 244 is YQ HSI. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] During operation, the canvas tube 223 is fixedly installed on the outside of the outer shell 221, connecting the outer shell 221 and the movable frame 224. This prevents the vibration generated by the shot blaster 233, which is fixed on the outside of the movable frame 224, from being efficiently transmitted to the outer shell 221. At the same time, the damping pad 211 above the base plate 1 can dampen the support frame 212 and the upper outer shell 221. This method can avoid a soft connection between the main vibration source, the shot blaster 233, and the outer shell 221, thus preventing vibration from affecting the structural strength of the outer shell 221. The connecting blocks 243 at both ends of the connecting frame 242 restrict the rotation axis and position of the damping rods 244 on both sides. The top of the damping rod 244 is rotatably connected to the adapter block 246. The adapter block 246 is connected to the bottom of the movable frame 224. The position blocks 247 are rotatably connected. The initial included angle between the base 241 and the connecting frame 242, and between the transition block 246 and the limiting block 247 is 150 degrees. Since the base 241 and the connecting frame 242 are rotatably connected, when the vibration generated by the shot blaster 233 is transmitted to the upper part of the movable frame 224, the included angle between the base 241 and the connecting frame 242, and between the transition block 246 and the limiting block 247 will change. The force generated by the vibration is absorbed by the contraction of the damping rod 244, which is converted into the internal energy of the damping rod 244 and restored by the outer spring 245. In this way, the damping rod 244 can reduce the vibration in the vertical direction while absorbing the force generated by the vibration in the horizontal direction, so as to improve the vibration resistance effect.
