When in use, in order to extend the conveying length, multiple conveyor belt machines 1 are connected end to end, refer to the attached Figure 1 As shown, the conveyor belt 1 on the left transports the stainless steel pump and valve castings from left to right. When the stainless steel pump and valve castings are transported to the right end of the conveyor belt 1 on the left, the stainless steel pump and valve castings fall on the connecting plate 2. The stainless steel pump and valve castings continue to slide with inertia until they slide onto the conveyor belt 1 on the right. The addition of the guide roller 10 ensures that the stainless steel pump and valve castings slide smoothly on the connecting plate 2. At this time, the connecting plate 2 is used to connect the gap between the two conveyor belts 1 to ensure that the stainless steel pump and valve castings can slide from the conveyor belt 1 on the left to the connecting plate 2 on the right.

[0032] The bracket 3 is a "T"-shaped plate structure. The bracket 3 is fixed to the bottom surface of the connecting plate 2 by the second screw 7. A rubber pad 29 is fixed to the bottom surface of the bracket 3. A plurality of first screws 5 are fixed to the bottom surface of the bracket 3. The first screw 5 passes through the through hole 4. The through hole 4 is provided on the bottom plate of the frame of the conveyor belt machine 1. The bottom end of the first screw 5 is screwed with a nut 6. After the nut 6 is screwed and locked on the first screw 5, the rubber pad 29 is clamped between the bracket 3 and the bottom plate of the frame of the conveyor belt machine 1 to produce elastic deformation; a slope 11 is provided on the bottom surface of the mounting groove 8, and the slope 11 is inclined downward from both sides of the mounting groove 8 to the center. A through opening 12 is provided on the bottom surface of the connecting plate 2, and the through opening 12 is connected to the slope 11. A chip storage groove 13 is provided on the top surface of the bracket 3. The bracket 3 is placed under the connecting plate 2 in advance, and then the bracket 3 is fixed to the bottom surface of the connecting plate 2 with the help of the second screw 7, that is, the second screw 7 passes through the top plate of the bracket 3 and is screwed to the bottom surface of the connecting plate 2. At this time, the connecting plate 2 and the bracket 3 are fixed together. When the connecting plate 2 and the bracket 3 are placed between the two conveyor belts 1, the first screw 5 passes through the through hole 4, and then the nut 6 is sleeved and screwed to the bottom end of the first screw 5. When the nut 6 is tightened, the nut 6 rests on the bottom surface of the frame bottom plate of the conveyor belt 1. At this time, the rubber pad 29 is clamped between the bracket 3 and the conveyor belt. 1, acts as an elastic gasket after the first screw 5 and the nut 6 are screwed together, and the connecting plate 2 transfers the load of the stainless steel pump valve casting to the frame bottom plate of the conveyor belt machine 1 through the bracket 3; the dust falling from the gap of the guide roller 10 slides along the slope 11 to the through port 12 and then falls into the chip storage trough 13 for storage, that is, the bracket 3 not only supports the connecting plate 2, but also stores the dust falling from the connecting plate 2, and cooperates with the first screw 5 to be fixed on the frame bottom plate of the conveyor belt machine 1 to complete the installation of the connecting plate 2, so that the bracket 3 has multiple uses and rich functions.

[0033] The top surface of the connecting plate 2 is fixed with hanging plates 16 at both ends, and the bottom end of the hanging plate 16 is inserted into the surface of the chip storage rack 18. The surface of the chip storage rack 18 is screwed with a hand screw 19, and one end of the hand screw 19 is screwed to the surface of the hanging plate 16. Brush plates 15 are installed on both sides of the bracket 3. A blanking port 22 is provided on the bottom plate of the frame of the conveyor machine 1. Side grooves 14 are provided on both sides of the bracket 3. The brush plates 15 are inserted into the side grooves 14. The brush plates 15 are fixed in the side grooves 14 by screws, and the bristles of the brush plates 15 are in contact with the conveyor belt of the conveyor machine 1; the hanging plate 16 is a "J"-shaped plate structure, and the hanging plate 16 is overlapped on the frame side panels of the two conveyor machines 1. The chip storage rack 18 is a square frame, and both ends of the chip storage rack 18 A socket 17 is provided on each of them, and the bottom end of the hanging plate 16 is inserted into the socket 17; a reserved opening 20 is provided on the bottom surface of the chip storage rack 18, and a protective frame 21 is fixed inside the reserved opening 20, and a sealing gasket 30 is fixed on the top surface of the reserved opening 20. The sealing gasket 30 is a ring-shaped plate, and the sealing gasket 30 is clamped between the chip storage rack 18 and the bottom plate of the frame of the conveyor machine 1, and the first screw 5 is in the inner ring mouth of the protective frame 21; the conveyor machine 1 is fixed with a pad 23 and a ramp plate 24 on the top surface of the bottom plate of the frame, and the pad 23 and the ramp plate 24 are symmetrically distributed about the blanking port 22. After the brush plate 15 slides the dust swept off the conveyor belt of the conveyor machine 1 along the pad 23 and the ramp plate 24 to the blanking port 22, the dust falls into the chip storage rack 18.

[0034] When in use, after the connecting plate 2 is pushed between the two conveyor belt machines 1, the top plate of the hanging plate 16 is overlapped on the frame side plates of the two conveyor belt machines 1. At this time, the chip storage rack 18 is pushed from the bottom up from the bottom of the frame of the conveyor belt machine 1 until the bottom end of the hanging plate 16 is inserted into the socket 17, and the sealing gasket 30 is clamped between the top surface of the chip storage rack 18 and the bottom surface of the frame of the conveyor belt machine 1. The hand screw 19 is screwed and inserted into the surface of the hanging plate 16 to realize the anti-slip limit of the chip storage rack 18. The hanging plate 16 not only realizes the hanging limit of the connecting plate 2, but also realizes the hanging limit of the chip storage rack 18. That is, the hanging plate 16 has two uses and is rich in functions. The conveyor belt of the conveyor belt machine 1 rotates during During the process, the brush plate 15 sweeps off the dust on the surface of the conveyor belt of the conveyor machine 1, and the swept dust falls into the chip storage rack 18 through the drop port 22. In this way, the bracket 3 not only cooperates with the brush plate 15 to clean the conveyor belt surface of the conveyor machine 1, but also the bracket 3 supports the connecting plate 2 and collects the dust falling from the connecting plate 2. It is also fixed on the frame bottom plate of the conveyor machine 1 with the first screw 5 to complete the installation of the connecting plate 2, so that the bracket 3 has multiple uses and rich functions. The reason why the protective frame 21 is installed at the bottom of the chip storage rack 18 is to reserve space for loading and unloading the nut 6, that is, the fallen dust is collected in the space between the chip storage rack 18 and the protective frame 21.

[0035] Lugs 25 are fixed to both sides of the hanging plate 16. Lugs 25 define an inner cavity 26, and an air pump 27 is mounted on the surface of the lugs 25. Through holes 28 are formed on the surface of the lugs 25. The lugs 25 draw in external air, inject it into the inner cavity 26, and then eject it through the through holes 28. The through holes 28 are bell-shaped, and there are multiple through holes 28, equidistantly spaced and equally sized along the long side of the bottom surface of the inner cavity 26. When the air pump 27 is activated, it injects air into the inner cavity 26, which is then ejected through the through holes 28. The ejected air blows away dust and debris from the conveyor belt 1 and the stainless steel pump and valve castings. The hanging plate 16 not only limits the suspension of the connecting plate 2 but also limits the suspension of the chip storage rack 18. Furthermore, the lugs 25 on both sides of the hanging plate 16 provide a chip-blowing function, meaning that the hanging plate 16 serves multiple purposes.

[0036] To use the feeding and conveying mechanism for stainless steel pump and valve casting production: Place bracket 3 below adapter plate 2. Insert second screw 7 through the top plate of bracket 3 and screw it to the bottom of adapter plate 2, securing adapter plate 2 and bracket 3 together. Rubber pad 29 is now positioned between bracket 3 and adapter plate 2. Place the assembled adapter plate 2 and bracket 3 between two conveyors 1, inserting first screw 5 through hole 4 in the bottom plate of conveyor 1. Slip nut 6 onto the bottom end of first screw 5 and tighten until it rests against the bottom of the conveyor 1 frame. Rubber pad 29 is now clamped between bracket 3 and the conveyor 1 frame, completing the initial securement of adapter plate 2 to conveyor 1 via bracket 3. The adapter plate 2 then transfers the load of the stainless steel pump and valve casting to the conveyor 1 frame. Insert the brush plate 15 into the side grooves 14 on either side of the bracket 3 and secure it with screws, ensuring the bristles of the brush plate 15 contact the conveyor belt of the conveyor 1. Fasten the hanging plates 16 to the ends of the top surface of the connecting plate 2. The hanging plates 16 are J-shaped, with their top plates later overlapping the side panels of the two conveyor frames 1. Once the connecting plate 2 is inserted between the two conveyor frames 1, push the chip hopper 18 upward from the bottom of the conveyor frame 1, inserting the bottom ends of the hanging plates 16 into the sockets 17 at each end of the chip hopper 18. The sealing gasket 30 (annular plate, secured to the top surface of the reserved opening 20) is now clamped between the top surface of the chip hopper 18 and the bottom surface of the conveyor frame 1. Tighten the hand screws 19 that engage the hanging plates 16 to prevent the chip hopper 18 from falling out. The protective frame 21 is inserted and fixed inside the reserved opening 20 opened on the bottom surface of the chip storage frame 18. The first screw 5 is in the inner ring opening of the protective frame 21. The protective frame 21 is used to reserve space for loading and unloading the nut 6. The falling dust is collected in the space between the chip storage frame 18 and the protective frame 21.

[0037] Turn on the two conveyor belts 1 and start rotating them. The conveyor belt 1 on the left transports the stainless steel pump and valve castings from left to right. Casting transportation and connection: When the stainless steel pump and valve castings are transported to the right end of the conveyor belt 1 on the left, they fall onto the connecting plate 2. The stainless steel pump and valve castings continue to slide due to inertia, and the guide rollers 10 ensure smooth sliding until they slide onto the conveyor belt 1 on the right, thus achieving the transportation connection between the two conveyor belts 1. During the rotation of the conveyor belt of the conveyor belt 1, the brush plate 15 sweeps off the dust on the surface of the conveyor belt of the conveyor belt 1. The swept dust slides along the pad 23 and the ramp plate 24 (fixed on the top surface of the bottom plate of the conveyor belt 1 frame, symmetrically distributed about the drop-out port 22) to the drop-out port 22, and then falls into the chip storage rack 18. Dust falling through the gaps in the guide rollers 10 slides down the slope 11 on the bottom of the mounting slot 8 on the top surface of the connecting plate 2 to the opening 12, where it falls into the chip trough 13 on the top surface of the bracket 3. When the air pump 27 is activated, it draws in outside air and injects it into the inner cavity 26 within the ear plate 25. The air within the inner cavity 26 is ejected through multiple, bell-shaped holes 28 equidistantly spaced and sized along the long side of the bottom surface of the inner cavity 26, blowing away dust from the conveyor belt 1 and the stainless steel pump and valve castings. Regularly clean dust collected in the chip trough 18 and chip trough 13 to prevent dust accumulation that may affect normal operation. Regularly check the tightness of all connecting components (such as the second screw 7, the first screw 5, the nut 6, and the hand screw 19) and tighten them immediately if loose. Inspect the conveyor belt, guide rollers 10, brush plate 15, and other components for wear and replace them if severely worn. Regularly check the working status of the air pump 27, clean the air inlet and through hole 28 of the air pump 27 to prevent blockage, and ensure that the chip blowing function is normal.

[0038] The differences between the "a feeding and conveying mechanism for producing stainless steel pump and valve castings" proposed in the present invention and the existing conveyor are as follows:

[0039] Existing conveyors usually use a single conveyor belt or multiple conveyor belts that are simply connected, and lack a special connection design; the present invention connects two conveyor belts 1 end to end, and provides a connection plate 2 between them to ensure smooth sliding of stainless steel pump and valve castings.

[0040] Existing conveyors are usually flat or simple inclined designs, lacking auxiliary sliding structures such as guide rollers; the present invention is an inverted table-type plate with arc-shaped side walls and a mounting groove 8 on the top surface for installing a limit shaft 9 and a guide roller 10.

[0041] Existing conveyors are usually not equipped with guide rollers, which may hinder the sliding of castings. In the present invention, a plurality of guide rollers 10 are rotatably connected to the top surface of the connecting plate 2 to ensure smooth sliding of the castings.

[0042] Existing conveyors usually do not have a special bracket design, and the fixing method may be relatively simple, lacking elastic deformation and stability design; the present invention uses a bracket 3 in a "T" shape, which is fixed to the bottom surface of the connecting plate 2 through a second screw 7. The bottom surface has a rubber pad 29 and a first screw 5. The first screw 5 passes through the bottom plate of the conveyor belt machine 1 and is fixed with a nut 6.

[0043] Existing conveyors usually rely on manual or simple cleaning devices to clean dust, and lack an automated dust collection system; the present invention installs brush plates 15 on both sides of the bracket 3, and the bristles contact the conveyor belt, sweeping the dust and dropping it into the chip storage rack 18 through the drop port 22; the dust falling from the gap between the guide roller 10 of the connecting plate 2 slides along the slope 11 to the through port 12 and then falls into the chip storage trough 13.

[0044] Existing conveyors usually do not have a special chip storage rack design, and dust may be scattered everywhere; the present invention uses a chip storage rack 18 in the form of a square frame with sockets 17 at both ends, which are plugged into the bottom end of the hanging plate 16; a reserved opening 20 is opened on the bottom surface, and a protective frame 21 is plugged and fixed inside.

[0045] Existing conveyors usually do not have a chip blowing function, and the cleaning effect may be poor. The present invention has ear plates 25 fixed on both sides of the hanging plate 16, an inner cavity 26 is provided inside, and an air pump 27 is installed on the surface. Gas is ejected through the through hole 28 to blow away dust and chips on the conveyor belt and the surface of the casting.

[0046] The existing conveyor structure may be bulky, installation and maintenance may not be convenient, and component replacement may be difficult; the present invention has a compact structure, reasonable design, and clear installation steps, which facilitates operators to perform quick and accurate installation; each component is easy to disassemble and replace, and maintenance is simple.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
