Detailed implementation manner

[0017] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0018] Please refer to Figures 1 to 13 , the present invention provides a technical solution: a feeding and conveying mechanism for the production of stainless steel pump valve castings, including two conveyor belt machines 1, the two conveyor belt machines 1 are connected end to end, a connecting plate 2 is arranged between the two conveyor belt machines 1, a bracket 3 is installed at the bottom of the connecting plate 2, a plurality of guide rollers 10 are rotatably connected to the top surface of the connecting plate 2, the connecting plate 2 is an inverted trapezoidal plate, both side walls of the connecting plate 2 are arc surfaces, an installation groove 8 is opened on the top surface of the connecting plate 2, a plurality of limiting shafts 9 are fixed between the two parallel side walls of the installation groove 8, guide rollers 10 are sleeved on the rod bodies of the limiting shafts 9, and the top surfaces of the guide rollers 10 and the top surface of the conveyor belt of the connecting plate 2 are coplanar. When in use, in order to extend the conveying length, the multiple conveyor belt machines 1 are connected end to end. Refer to the attached Figure 1 As shown, the conveyor belt machine 1 on the left conveys the stainless steel pump valve castings from left to right. When the stainless steel pump valve castings are conveyed to the right end of the conveyor belt machine 1 on the left, the stainless steel pump valve castings fall on the connecting plate 2, and the stainless steel pump valve castings continue to slide due to inertia until the stainless steel pump valve castings slide onto the conveyor belt machine 1 on the right. The addition of the guide rollers 10 ensures that the stainless steel pump 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 belt machines 1 to ensure that the stainless steel pump valve castings can slide from the conveyor belt machine 1 on the left to the connecting plate 2 on the right.

[0019] The bracket 3 is in a "T"-shaped plate structure. The bracket 3 is fixed to the bottom surface of the connecting plate 2 through the connecting screw 7. A rubber pad 29 is fixed to the bottom surface of the bracket 3. A plurality of screws 5 are fixed to the bottom surface of the bracket 3. The screws 5 penetrate through the through holes 4, and the through holes 4 are opened on the frame bottom plate of the conveyor 1. A nut 6 is screwed to the bottom end of the screw 5. After the nut 6 is screwed and locked on the screw 5, the rubber pad 29 is clamped between the bracket 3 and the frame bottom plate of the conveyor 1 to generate elastic deformation; a slope 11 is opened on the bottom surface of the installation groove 8, and the slope 11 slopes downward from both sides to the center of the installation groove 8. A through port 12 is opened on the bottom surface of the connecting plate 2, and the through port 12 communicates with the slope 11. A chip storage groove 13 is opened on the top surface of the bracket 3. First, place the bracket 3 under the connecting plate 2, and then fix the bracket 3 to the bottom surface of the connecting plate 2 by means of the connecting screw 7, that is, the connecting screw 7 penetrates 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 two conveyors 1, the screw 5 penetrates through the through hole 4, and then the nut 6 is sleeved and screwed to the bottom end of the screw 5. When the nut 6 is tightened, the nut 6 abuts against the bottom surface of the frame bottom plate of the conveyor 1. At this time, the rubber pad 29 is clamped between the bracket 3 and the frame bottom plate of the conveyor 1, acting as an elastic gasket after the screw 5 and the nut 6 are screwed together. The connecting plate 2 transfers the load of the stainless steel pump valve casting to the frame bottom plate of the conveyor 1 through the bracket 3; the dust falling from the gap of the guide roller 10 slides down along the slope 11 to the through port 12 and then falls into the chip storage groove 13 for storage. That is, the bracket 3 not only realizes the support of the connecting plate 2, but also realizes the storage of the dust and chips falling from the connecting plate 2, and is fixed to the frame bottom plate of the conveyor 1 in cooperation with the screw 5 to complete the installation of the connecting plate 2. Thus, the bracket 3 serves multiple purposes and has rich functions.

[0020] At both ends of the top surface of the connecting plate 2, hanging plates 16 are fixed. The bottom ends of the hanging plates 16 are inserted into the surface of the chip storage rack 18. A hand-tightening screw 19 is screwed on the surface of the chip storage rack 18. One end of the hand-tightening screw 19 is screwed on the surface of the hanging plate 16. Brush plates 15 are installed on both sides of the bracket 3. A blanking port 22 is formed on the frame bottom plate of the conveyor 1. Side grooves 14 are formed on both sides of the bracket 3. The brush plates 15 are inserted into the side grooves 14 and fixed in the side grooves 14 by screws. The bristles of the brush plates 15 are in contact with the conveyor belt of the conveyor 1; the hanging plate 16 is in a "J"-shaped plate structure and overlaps on the side plates of the frames of the two conveyors 1. The chip storage rack 18 is in a square frame shape. Insertion ports 17 are formed at both ends of the chip storage rack 18. The bottom end of the hanging plate 16 is inserted into the insertion ports 17; a reserved port 20 is formed on the bottom surface of the chip storage rack 18. A protective frame 21 is inserted and fixed inside the reserved port 20. A sealing gasket 30 is fixed on the top surface of the reserved port 20. The sealing gasket 30 is in an annular plate shape and is clamped between the chip storage rack 18 and the frame bottom plate of the conveyor 1. The screw 5 is located in the inner ring opening of the protective frame 21; on the top surface of the frame bottom plate of the conveyor 1, a cushion plate 23 and a slope plate 24 are fixed. The cushion plate 23 and the slope plate 24 are symmetrically distributed with respect to the blanking port 22. After the brush plates 15 sweep the dust and chips falling from the conveyor belt of the conveyor 1 along the cushion plate 23 and the slope plate 24 and slide them into the blanking port 22, the dust and chips fall into the chip storage rack 18.

[0021] During use, after the connecting plate 2 is pushed between the two conveyors 1, the top plate of the hanging plate 16 overlaps on the side plates of the frames of the two conveyors 1. At this time, the chip storage rack 18 is pushed from the bottom up of the frame of the conveyor 1 until the bottom end of the hanging plate 16 is inserted into the insertion port 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 1. Then, the hand-tightening screw 19 is screwed and inserted on the surface of the hanging plate 16 to realize the anti-disengagement 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 serves two purposes and has rich functions; during the rotation of the conveyor belt of the conveyor 1, the brush plates 15 sweep the dust and chips on the surface of the conveyor belt of the conveyor 1. After being swept, the dust and chips fall into the chip storage rack 18 through the blanking port 22. In this way, the bracket 3 not only cooperates with the brush plates 15 to clean the surface of the conveyor belt of the conveyor 1, but also the bracket 3 supports the connecting plate 2, and realizes the collection of the dust and chips falling from the connecting plate 2, and is fixed on the frame bottom plate of the conveyor 1 in cooperation with the screw 5 to complete the installation of the connecting plate 2. Thus, the bracket 3 serves multiple purposes and has rich functions; the reason for installing the protective frame 21 at the bottom of the chip storage rack 18 is to reserve space for loading and unloading the nut 6, that is, the falling dust and chips are collected in the space between the chip storage rack 18 and the protective frame 21.

[0022] Both sides of the hanging plate 16 are fixed with ear plates 25. An inner cavity 26 is provided inside the ear plate 25. An air pump 27 is installed on the surface of the ear plate 25. A through hole 28 is formed on the surface of the ear plate 25. After the ear plate 25 sucks in external air and injects it into the inner cavity 26, it is ejected through the through hole 28. The through hole 28 is in a flared shape, and there are multiple through holes 28, which are arranged equidistantly and in the same size along the long side of the bottom surface of the inner cavity 26. After triggering the switch of the air pump 27, the air pump 27 injects air into the inner cavity 26, and the gas inside the inner cavity 26 is ejected through the through hole 28. The ejected gas can blow off the dust and debris on the conveyor belt of the conveyor machine 1 and the surface of the stainless steel pump valve casting. The hanging plate 16 not only realizes the hanging and limiting of the connecting plate 2, but also realizes the hanging and limiting of the chip storage rack 18. Moreover, the hanging ear plates 25 on both sides of the hanging plate 16 realize the chip blowing function, that is, the hanging plate 16 has multiple functions.

[0023] Usage method of the feeding and conveying mechanism for the production of stainless steel pump valve castings: Place the bracket 3 under the connecting plate 2, and use the connecting screw 7 to pass through the top plate of the bracket 3 and then thread it on the bottom surface of the connecting plate 2 to fix the connecting plate 2 and the bracket 3 together. At this time, the rubber pad 29 is located between the bracket 3 and the connecting plate 2. Place the assembled connecting plate 2 and bracket 3 between the two conveyor machines 1, and make the screw 5 pass through the perforation 4 formed on the bottom plate of the frame of the conveyor machine 1. Set the nut 6 and thread it on the bottom end of the screw 5, and tighten the nut 6 so that the nut 6 abuts against the bottom surface of the frame bottom plate of the conveyor machine 1. At this time, the rubber pad 29 is clamped between the bracket 3 and the frame bottom plate of the conveyor machine 1, completing the preliminary fixation of the connecting plate 2 on the conveyor machine 1 through the bracket 3, and the connecting plate 2 transfers the load of the stainless steel pump valve casting to the frame bottom plate of the conveyor machine 1. Insert the brush plate 15 into the side grooves 14 formed on both sides of the bracket 3, and use screws to fix the brush plate 15 in the side grooves 14 so that the bristles of the brush plate 15 contact the conveyor belt of the conveyor machine 1. Fix the hanging plate 16 at both ends of the top surface of the connecting plate 2. The hanging plate 16 is in a "J"-shaped plate structure, and its top plate is used for subsequent lapping on the frame side plates of the two conveyor machines 1. After the connecting plate 2 is pushed between the two conveyor machines 1, push the chip storage rack 18 from the bottom up from the bottom of the frame of the conveyor machine 1 so that the bottom end of the hanging plate 16 is inserted into the sockets 17 formed at both ends of the chip storage rack 18. At this time, the sealing gasket 30 (in an annular plate shape, fixed on the top surface of the reserved opening 20) is clamped between the top surface of the chip storage rack 18 and the bottom surface of the frame of the conveyor machine 1. Screw the hand-tightening screw 19 and insert it on the surface of the hanging plate 16 to realize the anti-disengagement limit of the chip storage rack 18. Insert and fix the enclosing frame 21 into the reserved opening 20 formed on the bottom surface of the chip storage rack 18. The screw 5 is located in the inner ring opening of the enclosing frame 21. The enclosing frame 21 is used to reserve space for loading and unloading the nut 6, and the falling dust and debris are collected in the space between the chip storage rack 18 and the enclosing frame 21.

[0024] Turn on the two conveyor belts 1 to start the conveyor belts rotating. The left conveyor belt 1 conveys the stainless steel pump valve castings from left to right. Conveying and connection of the castings: When the stainless steel pump valve castings are conveyed to the right end of the left conveyor belt 1, they fall onto the connecting plate 2. The stainless steel pump valve castings continue to slide forward by inertia and, under the action of the guide rollers 10, ensure smooth sliding until they slide onto the right conveyor belt 1, achieving the conveying 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 and debris on the surface of the conveyor belt of the conveyor belt 1. The swept dust and debris slide along the backing plate 23 and the slope plate 24 (fixed on the top surface of the bottom plate of the conveyor belt 1 frame and symmetrically distributed about the material dropping opening 22) and fall into the material dropping opening 22 and then into the chip storage rack 18. The dust falling through the gaps of the guide rollers 10 slides along the slope surface 11 opened on the bottom surface of the installation groove 8 on the top surface of the connecting plate 2 and then into the through opening 12 and falls into the chip storage groove 13 opened on the top surface of the bracket 3 for storage. Trigger the switch of the air pump 27. After the air pump 27 sucks in external air, it injects it into the inner cavity 26 inside the ear plate 25. The gas inside the inner cavity 26 is ejected through a plurality of through holes 28 that are flared and arranged at equal distances and of equal size along the long side of the bottom surface of the inner cavity 26, blowing off the dust and debris on the surface of the conveyor belt of the conveyor belt 1 and the stainless steel pump valve castings. Regularly clean the dust and debris collected in the chip storage rack 18 and the chip storage groove 13 to prevent the accumulation of dust and debris from affecting the normal operation of the mechanism. Regularly check the fastening conditions of the various connecting components (such as the connecting screw 7, screw 5, nut 6, hand-tightening screw 19, etc.). If there is looseness, tighten it in time; check the wear conditions of components such as the conveyor belt, guide rollers 10, and brush plate 15. If there is severe wear, replace them in time. Regularly check the working status of the air pump 27, clean the air inlet and the through holes 28 of the air pump 27 to prevent blockage and ensure the normal chip blowing function.

[0025] The differences between the "loading and conveying mechanism for the production of stainless steel pump valve castings" proposed by the present invention and the existing conveyors are as follows: Existing conveyors usually use a single conveyor belt or simply connect multiple conveyor belts, lacking a special connection design; the present invention connects the two conveyor belts 1 end to end, with a connecting plate 2 provided between them to ensure smooth sliding of the stainless steel pump valve castings.

[0026] Existing conveyors usually have a flat plate or simple inclined plane design, lacking auxiliary sliding structures such as guide rollers; the present invention is in the shape of an inverted table-shaped plate, with the two side walls being arc-shaped surfaces, and an installation groove 8 is opened on the top surface, on which a limiting shaft 9 and guide rollers 10 are installed.

[0027] Existing conveyors usually do not have a guide roller configuration, and the sliding of the castings may be blocked; 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.

[0028] 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 connecting screw 7, and the bottom surface has a rubber pad 29 and a screw 5. The screw 5 passes through the bottom plate of the conveyor belt machine 1 frame and is fixed with a nut 6.

[0029] 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 rollers 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.

[0030] 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 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.

[0031] Existing conveyors usually do not have a chip blowing function and the cleaning effect may be poor. In the present invention, ear plates 25 are 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 on the conveyor belt and the surface of the casting.

[0032] 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 is convenient for operators to perform quick and accurate installation; each component is easy to disassemble and replace, and maintenance is simple.

[0033] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
