Description

Technical Field

[0001] The present invention relates to the technical field of shot blasting machines, and particularly to a sealing device for a shot blasting machine. Background Art

[0002] A shot blasting machine refers to a casting equipment that uses high-speed steel shots ejected by a shot blasting device to clean or strengthen the surface of castings. The shot blasting machine can simultaneously perform sand falling, core removal, and cleaning on castings. In the prior art, a sealing mechanism is usually installed on the top of the shot blasting machine to prevent high-speed steel shots from flying out and injuring people. However, currently, domestic shot blasting machines usually adopt a simple structure of felt, asbestos, rubber plus two protective doors to achieve single-layer sealing, and a baffle is provided between the two doors to prevent steel shots from flying out of the chamber. However, as the sealing strip ages, the sealing effect will gradually decrease, and then steel shot splashing, serious dust leakage, and waste of steel shots are likely to occur. At the same time, the bottom of some shot blasting machines is not reasonably designed, and the steel shots and workpiece waste are irregular at the bottom, which is not conducive to the cleaning operation of employees. In addition, the poor sealing of the shot blasting machine will cause greater noise during the shot blasting process. Prolonged exposure to a high-intensity noise environment will cause damage to people's hearing, and even hearing loss. Summary of the Invention

[0025] Embodiment

[0026] As Figures 1 to 3 shown, a shot blasting machine sealing device proposed by the present invention includes a shot blasting machine body 1, and further includes: a sealing mechanism 2, a double-layer guide plate 11, a hoist tooling 3 and a sealing plate mechanism arranged in the shot blasting machine body 1. After the top sealing plate 13 is adopted for the shot blasting machine body 1, not only the utilization rate of steel shots is increased by 30%, but also the cleaning operation time of employees is reduced, and working hours can be saved every day. The lifting operation of the hoist tooling 3 is controlled by a PLC (controller), which improves the operation efficiency and significantly improves the operation time compared with the original manual lifting operation. At the same time, a double-door structure is adopted, and the opening and closing of the door are controlled by the PLC. Compared with the original manual opening of the door, the operation time is further improved. A guide port 12 for the flow of steel shots is provided inside the shot blasting machine body 1, and the guide port 12 allows the steel shots to flow down through the gap, enabling the steel shots to be recycled again, improving the service life of the steel shots and reducing the cost. A hook 14 is provided at one end of the sealing mechanism 2 away from the chain hoist 31.

[0027] Among them, as Figure 1 and Figure 2As shown, the sealing mechanism 2 includes a pair of brush 24, first sealing plate 21, second sealing plate 22, and third sealing plate 23 that are sequentially installed from top to bottom. The brush 24 is made of steel wire. Since steel wire has high strength and rigidity and can withstand large impact forces, for high-speed projected steel shots, the steel wire brush can directly block the advancement of steel shots by virtue of its firm characteristics, effectively preventing steel shots from flying out of the shot blasting area, and is suitable for occasions with high requirements for blocking strength. At the same time, the steel wire is generally surface-treated such as galvanized or nickel-plated to make it have good corrosion resistance. In the harsh environment inside the shot blasting machine, it is not easy to rust, can maintain good performance for a long time, and maintain the blocking effect on the shot blasting impact force. In addition, even under a strong shot blasting impact force, the steel wire can better maintain its shape and will not easily deform or twist, so as to always maintain an effective blocking area and structure, ensuring the reliability of the blocking function. The brush 24, first sealing plate 21, second sealing plate 22, and third sealing plate 23 are arranged in a four-layer structure. When the steel shots pass through the three lower sealing plates and then the top brush, the speed of the high-speed steel shots can be gradually attenuated, so that the steel shots will not fly out from the top of the equipment. At the same time, they all adopt an external disassembly and assembly method, which is safe and simple to operate. The brush 24, first sealing plate 21, second sealing plate 22, and third sealing plate 23 are fixedly connected by fixing bolts 25. The first sealing plate 21, second sealing plate 22, and third sealing plate 23 are sealing plates, which connect multiple sealing plates into an integral structure, improving the strength and rigidity of the entire sealing system. When the equipment needs to be maintained or repaired, the sealing plates need to be disassembled for inspection, repair, or replacement. Using the fixing bolts 25 to connect, only by unscrewing the bolts, the sealing plates can be easily disassembled, the operation is simple and fast, reducing the maintenance cost and difficulty. The sealing plate mechanism includes a top sealing plate 13 and a bottom sealing plate 15. The materials of the top sealing plate 13 and the bottom sealing plate 15 are made of high manganese steel, and the high manganese steel material improves the stability of the hoist walking and lifting. The shape of the bottom sealing plate 15 is set in a V shape. The V-shaped bottom sealing plate 15 is conducive to the collection of steel shots and the concentration of waste after casting shot blasting, facilitating the cleaning operation of later employees. The hoist tooling 3 includes a chain hoist 31, a chain funnel 32, a moving rod 33, a fixed rod 34, a connecting block 35, a lower limit block 36, an upper limit block 37, a hanger positioning tooling 38, and a rotating disk 39. The chain hoist 31 is a common mechanical equipment for hoisting and lifting. Its composition structure includes a driving device, a chain, a sprocket, a braking device, and a hook. Among them, the driving device includes a motor or a manual driving mechanism. The motor-driven chain hoist has a high hoisting efficiency and can realize the lifting and lowering of heavy objects through electric drive. The chain is usually an annular chain made of high-strength alloy steel and is a key component for the chain hoist to realize the hoisting function. The chain has high strength and wear resistance and can withstand large tensile forces, ensuring the safety and reliability of the hoisting process. Among them, the sprocket is usually matched with the chain, and the rotation of the sprocket drives the movement of the chain, thereby realizing the lifting and lowering of heavy objects.Sprockets are usually made of high-quality steel and have good wear resistance and transmission performance after special processing and heat treatment processes. Secondly, the braking device is an important component to ensure the safe operation of the ring chain hoist, and generally adopts electromagnetic braking or mechanical braking methods. During the lifting process, when it is necessary to stop or hold the position of the heavy object, the braking device can quickly brake to prevent the chain from slipping and ensure the stability and safety of the heavy object. Finally, the hook is used to hang the heavy object and is usually forged from high-strength alloy steel, with sufficient strength and toughness. The shape and size of the hook are designed according to different usage requirements to adapt to various types of heavy object hoisting.

[0028] Secondly, as Figure 3 shown, the bottom of the fixed rod 34 is connected with a sealing cover 40 through a pair of connecting blocks 35. The lower limit block 36 and the upper limit block 37 can enable the moving rod 33 to achieve PLC (controller) automated control of lifting, reducing the original manual operation by manpower and improving production efficiency. The PLC controller is a digital computer used for automated control and is mainly used in industrial control systems. It controls the operation of mechanical equipment, production lines, robots, etc. through programming. PLCs are widely used in various automated systems, such as manufacturing, traffic control, energy management and other fields. The sealing cover 40 is arranged in an inverted V shape to prevent the steel shot from overflowing. A rotating disk 39 is provided on the lower surface of the middle part of the fixed rod 34. Both upper surfaces of the two ends of the fixed rod 34 are fixedly connected with moving rods 33. The top of the moving rod 33 is connected to the hoist tooling 3. The lower limit block 36 and the upper limit block 37 are arranged on the outer wall of the hoist tooling 3. The bottom end of the ring chain hoist 31 is provided with a chain 41, and the chain 41 is arranged corresponding to the chain funnel 32.

[0029] Furthermore, the shot blasting machine body 1 is provided with a pneumatic door 16, the pneumatic door 16. The pneumatic door 16 includes a rear door 161 and a front door 162. Both the rear door 161 and the front door 162 adopt the structure of automobile door seals, and the sealing of the door body itself is softer and more airtight. A pair of cylinders are provided on both the rear door 161 and the front door 162 and an automatic double-opening pneumatic door is adopted. Moreover, a duckbill cap structure is provided at the top of the rear door 161 and the front door 162. When the structure is embedded in the front end of the top seal to firmly seal the steel shot and dust after closing the door, its working principle is that the shape and size of the duckbill cap structure are designed to match the front end of the top seal. When closing the door, the duckbill cap structure can accurately embed into the front end of the top seal, forming a fit similar to a mortise and tenon structure, making the connection between the door and the top seal closer and reducing or even eliminating possible gaps. In addition, the duckbill cap structure protrudes from the top of the door. After embedding into the front end of the top seal, it forms an additional barrier between the door and the top seal. For the steel shot and dust that may splash or disperse upward, the duckbill cap structure can directly block them from passing through, intercepting them inside the door and playing a preliminary blocking role.

[0030] In this embodiment, when the shot blasting machine sealing device needs to be used, after starting the shot blasting machine body 1, the workpiece is first placed on the shot blasting hoist tooling 3, and then the shot blasting machine body 1 is started. After the internal equipment of the hoist tooling 3 is started, it moves to the equipment through the diversion port 12, and the shot blasting machine body 1 starts shot blasting. As the steel shots are ejected, only the sealing mechanism 2 needs to be opened, and then the brush 24, the first sealing plate 21, the second sealing plate 22, and the third sealing plate 23 are opened immediately. The steel shots first pass through the first sealing plate 21, the second sealing plate 22, and the third sealing plate 23, and then pass through the brush 24, so that the speed of the high-speed steel shots can be gradually attenuated, and at the same time, the steel shots will not fly out from the top of the equipment. Finally, the shot blasting machine body 1 can be stopped and reset for the next cycle. The hoist tooling 3 returns from the guide rail to the working area, and the shot blasted workpiece is removed, and then the next cycle can be started. During the use of the shot blasting machine body 1, after closing the rear door 161 and the front door 162 and cooperating with the top sealing plate 13 and the bottom sealing plate 15, since the "duckbill structure" is added to the door tops of the rear door 161 and the front door 162, after closing the rear door 161 and the front door 162, the structure is embedded in the front end of the top sealing plate 13, and the steel shots and dust can be firmly sealed.
