Description

Technical Field

[0001] This utility model belongs to the field of chain plate technology, specifically a continuous flipping chain plate mechanism for shot blasting machines. Background Technology

[0002] A chain plate is a plate-shaped transmission component made of metal or non-metal materials. It is usually used in conjunction with chains and sprockets to form a chain plate conveyor system. Its core function is to achieve continuous material conveying through chain drive. The chain plate for shot blasting machines is a conveyor chain plate specifically designed for shot blasting machines and is the core conveying component of the shot blasting machine.

[0003] However, the following problems were found in the implementation of the relevant technologies:

[0004] Most existing shot blasting machines using chain plate mechanisms require an additional flipping drive device to achieve workpiece flipping, which not only increases equipment cost and structural complexity, but also easily reduces operating efficiency due to the coordination problem of multiple devices; moreover, the conveyor transmission structure lacks precision, and the chain plate is prone to shaking during operation, resulting in unstable workpiece flipping position and affecting the multi-faceted shot blasting treatment effect;

[0005] Furthermore, the existing mechanism's shaft height is usually fixed, which cannot adapt to the flipping fulcrum requirements of workpieces of different sizes, resulting in poor versatility; the adjustment structure design is unreasonable, resulting in poor stability and easy loosening during adjustment, and the component connection method is complicated, making disassembly and maintenance inconvenient, with low adaptability and maintenance efficiency. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a continuous tilting chain plate mechanism for shot blasting machines, which features automatic tilting, stable conveying, flexible adjustment, and convenient maintenance. This invention uses a drive motor, sprockets, and chain to drive the chain plate components for conveying, combined with a rotating shaft guide linkage, to achieve automatic workpiece tilting and stable conveying, solving the problems of requiring additional tilting devices and chain plate swaying. Furthermore, the adjustable connection structure between the upright plate and the mounting block allows for flexible adjustment of the rotating shaft height and convenient assembly / disassembly, solving the problems of fixed rotating shaft height and inconvenient maintenance.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a continuous flipping chain plate mechanism for a shot blasting machine, comprising a support, a frame fixedly provided on the upper surface of the support, and a chain plate component provided within the frame, mounting blocks symmetrically fixed on both sides of the frame, and a vertical plate detachably provided on the outer side of the mounting blocks, a support frame fixedly provided on the upper surface of the vertical plate, the support frames on both sides being mirror-distributed, and a rotating shaft provided between two corresponding support frames.

[0008] Preferably, the frame is symmetrically fixed with limiting plates on both sides, and the inner side of the limiting plates is provided with sprockets. The outer surfaces of the two sprockets on one side are meshed with a chain, and the outer surface of the chain is fixedly connected to the chain plate.

[0009] Preferably, a support plate is fixedly installed inside the bracket, and a drive motor is fixedly installed on the upper surface of the support plate. The output end of the drive motor is connected to one of the sprockets.

[0010] Preferably, the outer surface of the upright plate is threaded with a positioning bolt, and the positioning bolt is threaded into the corresponding mounting block. The outer surface of the upright plate is symmetrically provided with a number of bolt grooves that are distributed at the same vertical spacing to cooperate with the positioning bolt.

[0011] Preferably, the inner side of the upright plate is fixedly provided with an insert strip, and the insert strip is snapped onto the corresponding mounting block. The two sides of the mounting block are symmetrically fixed with protective plates, and the inner side of the protective plates is movably fitted with the corresponding upright plate.

[0012] Preferably, spring columns are symmetrically fixed to one inner wall of the support frame, and a support block is fixed to the end of the spring column. A support plate is fixed to the inner side of the support block, and the inner side of the support plate is rotatably connected to the corresponding rotating shaft.

[0013] Preferably, a limiting block is fixedly provided on the outer side of the support block, and a positioning column is fixedly provided inside the support frame, with the positioning column passing through the corresponding limiting block and fixedly provided with a limiting plate.

[0014] Preferably, reinforcing frames are symmetrically fixed on the outer surface of the frame, and side stops are symmetrically fixed to the upper parts of both sides of the frame by bolts.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model achieves continuous and uniform conveying through the transmission cooperation of the drive motor, sprocket, and chain, providing a stable power foundation for workpiece flipping. The rotating shaft, as a guide structure, forms a linkage with the chain plate transmission, enabling the workpiece to automatically flip during conveying without the need for an additional flipping drive device, thus improving the efficiency of shot blasting machine in multi-faceted workpiece processing. The high meshing transmission precision of the sprocket and chain, combined with the limiting effect of the limiting plate, reduces the shaking of the chain plate during operation, ensuring the positional stability of the workpiece during flipping.

[0017] 2. This utility model allows for flexible adjustment of the shaft height through the cooperation of the positioning bolts and bolt slots of different heights on the upright plate. This meets the flipping fulcrum requirements of workpieces of different sizes (e.g., the shaft height needs to be lowered for small workpieces to avoid over-flipping, while the shaft height needs to be increased for large workpieces to ensure smooth flipping). The interlocking structure of the insert and the mounting block, as well as the fitting design of the guard plate and the upright plate, ensure the stability of the upright plate during adjustment and prevent loosening after adjustment. In addition, the detachable connection of the positioning bolts facilitates the disassembly and maintenance of the upright plate, improving the adaptability and ease of maintenance of the mechanism.

[0023] 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.

[0024] like Figures 1 to 4As shown, this utility model provides a continuous tilting chain plate mechanism for a shot blasting machine, including a support 1, a frame 2 fixedly mounted on the upper surface of the support 1, and a chain plate component 3 inside the frame 2. Mounting blocks 41 are symmetrically fixed on both sides of the frame 2, and upright plates 42 are detachably mounted on the outer side of the mounting blocks 41. A support frame 4 is fixedly mounted on the upper surface of the upright plate 42. The support frames 4 on both sides are mirror-distributed, and a rotating shaft 5 is provided between two corresponding support frames 4. The rotating shaft 5 serves as a guide structure. When the workpiece is conveyed forward with the chain plate component 3 and contacts the rotating shaft 5, the workpiece will tilt around the rotating shaft 5 as a fulcrum under the thrust of the continuous transmission of the chain plate component 3 (the support frames 4 on both sides are mirror-distributed, which can form symmetrical guidance from both sides of the workpiece to ensure stable tilting posture).

[0025] Specifically, symmetrical limiting plates 12 are fixed on both sides of the frame 2, and sprockets 13 are rotatably mounted on the inner side of the limiting plates 12. The outer surfaces of the two sprockets 13 on one side are connected to a chain 14, and the outer surface of the chain 14 is fixedly connected to the chain plate 3. The two sprockets 13 on the same side are connected by the chain 14. When the sprockets 13 rotate, they will drive the chain 14 to move synchronously, and the chain plate 3 fixed on the outer surface of the chain 14 will move accordingly, thereby realizing the continuous conveying of the workpiece on the chain plate 3. At the same time, the limiting plates 12 on both sides of the frame 2 limit the sprockets 13, ensuring the stability of the sprockets 13 during rotation and preventing the chain 14 from disengaging.

[0026] Furthermore, a support plate 11 is fixedly installed inside the bracket 1, and a drive motor 15 is fixedly installed on the upper surface of the support plate 11. The output end of the drive motor 15 is connected to one of the sprockets 13. After the drive motor 15 on the support plate 11 inside the bracket 1 starts, its output end drives the sprocket 13 connected to it to rotate.

[0027] Furthermore, the outer surface of the upright plate 42 is threaded with a positioning bolt 43, and the positioning bolt 43 is threaded into the corresponding mounting block 41. The outer surface of the upright plate 42 is symmetrically provided with several bolt grooves 44 that are distributed at the same vertical spacing to cooperate with the positioning bolt 43. If it is necessary to adjust the height of the rotating shaft 5 according to the workpiece size (to adapt to the flipping fulcrum requirements of different workpieces), the positioning bolt 43 on the upright plate 42 can be unscrewed, and the upright plate 42 can be moved up and down along the mounting block 41. After the upright plate 42 is moved to the appropriate position, the positioning bolt 43 is passed through the bolt groove 44 of the corresponding height and screwed into the mounting block 41 to complete the height fixation of the support frame 4 and the rotating shaft 5.

[0028] It is worth noting that the inner side of the upright plate 42 is fixedly provided with a strip 46, and the strip 46 is snapped onto the corresponding mounting block 41. The two sides of the mounting block 41 are symmetrically fixed with guard plates 45, and the inner side of the guard plate 45 is movably fitted with the corresponding upright plate 42. The snapping structure between the strip 46 and the mounting block 41 ensures the stability of the movement direction. The guard plate 45 restricts the lateral displacement of the upright plate 42 from both sides during the movement and use of the upright plate 42.

[0029] It is worth noting that spring columns 52 are symmetrically fixed on one inner wall of the support frame 4, and a support block 53 is fixed at the end of the spring column 52. A support plate 54 is fixed on the inner side of the support block 53, and the inner side of the support plate 54 is rotatably connected to the corresponding rotating shaft 5. The spring column 52 on the inner wall of the support frame 4 drives the support plate 54 to closely adhere to the rotating shaft 5 through the support block 53. When the workpiece flips and contacts the rotating shaft 5, the spring column 52 can buffer the impact force through elastic deformation and reduce the vibration of the rotating shaft 5.

[0030] It is worth mentioning that a limiting block 55 is fixedly provided on the outer side of the support block 53, and a positioning post 56 is fixedly provided inside the support frame 4. The positioning post 56 passes through the corresponding limiting block 55 and is fixedly provided with a limiting plate 57. The limiting block 55 on the outer side of the support block 53 slides on the positioning post 56. With the help of the limiting plate 57, the movement range of the support block 53 can be limited, ensuring that the support plate 54 supports the rotating shaft 5 stably at all times, and avoiding the deviation of the rotating shaft 5 from affecting the workpiece flipping accuracy.

[0031] It is worth emphasizing that the outer surface of the frame 2 is symmetrically fixed with reinforcing frames 21, and the upper parts of both sides of the frame 2 are symmetrically fixed with side stops 22 by bolts. The reinforcing frames 21 on the outer surface of the frame 2 enhance the overall structural strength and prevent the frame 2 from deforming during long-term operation. The side stops 22 on the upper parts of both sides of the frame 2 form a blockage on the workpiece from the side to prevent the workpiece from slipping off the edge when it is transported or flipped.

[0032] The drive motor 15 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0033] Working principle: After the drive motor 15 on the inner support plate 11 of the bracket 1 starts, its output end drives the sprocket 13 connected to it to rotate. Since the two sprockets 13 on the same side are connected by the chain 14, the rotation of the sprocket 13 will drive the chain 14 to move synchronously, and the chain plate 3 fixed on the outer surface of the chain 14 will move accordingly, thereby realizing the continuous conveying of the workpiece on the chain plate 3. At the same time, the limiting plates 12 on both sides of the frame 2 play a limiting role on the sprocket 13, ensuring the stability of the sprocket 13 during rotation and preventing the chain 14 from disengaging.

[0034] As a guide structure, when the workpiece is conveyed forward with the chain plate 3 and comes into contact with the rotating shaft 5, the workpiece will flip around the rotating shaft 5 as a fulcrum under the thrust of the continuous transmission of the chain plate 3 (the two support frames 4 are mirrored and can form symmetrical guidance from both sides of the workpiece to ensure the stability of the flipping posture). The spring column 52 on the inner wall of the support frame 4 drives the support plate 54 to stick to the rotating shaft 5 through the support block 53. When the workpiece flips and contacts the rotating shaft 5, the spring column 52 can buffer the impact force through elastic deformation and reduce the vibration of the rotating shaft 5. The limiting block 55 on the outside of the support block 53 slides on the positioning column 56. With the help of the limiting plate 57, the movement range of the support block 53 can be limited to ensure that the support plate 54 supports the rotating shaft 5 stably and avoids the rotating shaft 5 from deviating and affecting the workpiece flipping accuracy.

[0035] If the height of the rotating shaft 5 needs to be adjusted according to the workpiece size (to adapt to the flipping fulcrum requirements of different workpieces), the positioning bolts 43 on the upright plate 42 can be unscrewed, and the upright plate 42 can be moved up and down along the mounting block 41 (the interlocking structure between the insert 46 and the mounting block 41 ensures the stability of the movement direction). After the upright plate 42 is moved to the appropriate position, the positioning bolts 43 are passed through the bolt grooves 44 of the corresponding height and screwed into the mounting block 41 to complete the height fixation of the support frame 4 and the rotating shaft 5. The guard plate 45 restricts the lateral displacement of the upright plate 42 from both sides during the movement and use of the upright plate 42.

[0036] The reinforcing frame 21 on the outer surface of the frame 2 enhances the overall structural strength and prevents the frame 2 from deforming during long-term operation; the side stops 22 on the upper sides of the frame 2 form a barrier against the workpiece from the side to prevent the workpiece from slipping off the edge when being transported or flipped.
