[0020] Advantages of the present invention:

[0021] 1) The fixed supports of the feeding assembly of the present invention are respectively provided with openings for reinforcing bar support facing upwards, and magnet members for adsorbing and fixing the reinforcing bars are fixedly connected to the openings. Driven by the driving mechanism, the fixed supports cyclically pass by the feeding end side of the spraying mechanism, thereby effectively conveying the reinforcing bar material to the feeding end side of the spraying mechanism at a uniform speed. Under the guiding and supporting of the lateral material supporting guide rollers of the feeding guiding mechanism, the reinforcing bar material passes through the inner hole of the longitudinal limiting cylinder and then enters the working station of the nozzle for spraying the coating material.

[0022] Through the support of the openings of the fixed supports and the adsorption and fixing method of the magnet members, the uniform conveying of the reinforcing bar material is ensured, and the front side of the spraying section of the reinforcing bar material is supported by the lateral material supporting guide rollers, thereby effectively preventing excessive sagging deformation of the spraying section of the reinforcing bar material; then, the radial position of the reinforcing bar material is limited through the inner hole of the longitudinal limiting cylinder to control the vibration amplitude generated when the reinforcing bar material leaves the magnet member within a reasonable range.

[0023] Thus, it can effectively and significantly improve the structural simplicity of the reinforcing bar feeding mechanism, so as to reduce the manufacturing and operating costs of the equipment; and it can greatly improve the uniformity of conveying the reinforcing bar material and reduce the influence of the vibration amount caused by the improvement of the uniformity, thereby effectively and greatly improving the spraying uniformity of the coating material.

[0024] 2) A feeding component is arranged on the front side of the feeding assembly of the present invention. The feeding component corresponds to the feeding assembly in position and has the same structure as the feeding assembly. Then, a feeding rack is arranged outside the feeding component, and a plurality of storage chains are horizontally arranged side by side outside the feeding rack. A plurality of lifting chains arranged in a staggered manner with the storage chains are upwardly inclined and installed on the feeding rack on the output end side of the storage chains. Driven by the two-axis motion mechanism, the position of the clamping jaw is controlled to regularly grab the reinforcing bar material stored on the baffle rod and place it on the feeding component. The reinforcing bar material enters the feeding component under the transmission of the feeding component for the next transmission and spraying work.

[0025] During the feeding process, the storage chain starts to convey the reinforcing bars arranged side by side on the storage chain to the position of the lifting chain. After the photoelectric sensor for detecting the reinforcing bars output from the storage chain detects the output of the reinforcing bar material, the storage chain stops operating and the lifting chain starts to lift the reinforcing bar material to the position where it falls into the transfer rod; after the reinforcing bar on the baffle rod is grabbed away, the driving cylinder drives the transfer rod to swing downward, so that the reinforcing bar material on the transfer rod falls onto the baffle rod, and then the storage chain and other components start again to store the single reinforcing bar material at the position of the transfer rod again. Thus, it effectively ensures feeding one by one as needed to ensure the continuous and coherent progress of the reinforcing bar spraying operation, thereby effectively assisting in improving the spraying efficiency of the reinforcing bar material of the present invention.

[0026] 3) On one side of the discharging end of the spraying mechanism of the present invention, there is a discharging component which corresponds to the position of the feeding component and has the same structure as the feeding component. The spraying mechanism, the feeding component, the feeding guiding mechanism, and the discharging component are respectively fixedly connected to the corresponding container body. Therefore, the spraying mechanism, the feeding component, the feeding guiding mechanism, and the discharging component of the present invention can be transported as a whole to the corresponding site for spraying processing operations, thereby effectively improving the use adaptability of the present invention.

[0027] 4) On one side of the discharging end of the discharging component of the present invention, there is a blanking mechanism. The blanking mechanism includes a blanking frame and a plurality of output rollers rotatably installed side by side on the blanking frame. The output rollers are used to output the steel bar materials after spraying. Then, the blanking cylinder is used to swing-drive the blanking rod to obliquely export the steel bar materials on the output rollers outward and make them fall into the storage iron chain of the H-shaped finished product storage part, so as to conveniently collect the steel bar materials after spraying.

[0028] 5) The top of the blanking rod of the present invention is movably clamped with a corresponding guiding rod. A counterweight block is fixedly connected to the outer end of the guiding rod. A corresponding trapezoidal chute is provided on the top end surface of the blanking rod. A guide block that is inserted into the trapezoidal chute is provided at the end of the guiding rod. When the blanking rod swings down to its place, the inner end of the blanking rod is inclined downward to ensure the reset of the guiding rod. When blanking is required, the blanking rod is controlled to swing upward. At this time, the guiding rod can move downward until the guide block is clamped at the end of the trapezoidal chute, thereby increasing the guiding stroke to ensure that the steel bar materials after spraying do not collide excessively with the storage iron chain or other materials stored on the storage iron chain during blanking, so as to prevent excessive damage to the surface of the steel bar materials after spraying.

[0029] 6) A damping mechanism is arranged in the longitudinal limiting cylinder of the present invention. When the vibration sensor detects that the vibration amount formed by the rotation of the transverse material supporting and guiding roller is greater than the set value V1, it can be determined that the steel bar materials are in a large vibration state at this time. At this time, the external air compressor is controlled to inject high-pressure gas into the driving cavity to drive each installation piston to move towards the inner hole side of the longitudinal limiting cylinder, so that each supporting ball respectively abuts against the surface of the steel bar to transfer the vibration amount of the steel bar to the longitudinal limiting cylinder, and effective damping is carried out under the friction energy consumption of the damping particles for damping. When the vibration sensor detects that the vibration amount formed by the rotation of the transverse material supporting and guiding roller is less than the set value V2, the pressure relief valve is controlled to open for pressure relief, and the installation piston is reset under the drive of the limiting spring. Thus, on the premise of not affecting the uniform conveying of the steel bar materials and reducing the wear amount of the supporting balls and the steel bar materials, the vibration amount of the steel bar materials is effectively and practically controlled within a lower range to further greatly improve the spraying uniformity of the coating materials.

Specific embodiments

[0047] For the convenience of those skilled in the art to understand, the embodiments will now be further described in detail in conjunction with the attached drawings for the structure of the present invention:

[0048] Reference Figure 1-16 , a spraying device for the surface coating of steel bars, comprising:

[0049] The spraying mechanism 1 includes at least one nozzle 101 for spraying the corresponding coating material onto the surface of the steel bar material. In this embodiment, there are three nozzles 101, which are arranged at equal angles of 120°, and surplus material collecting hoppers 102 are respectively arranged outside the discharging ends of the three nozzles. The surplus material collecting hoppers 102 are connected to the intake ends of the corresponding exhaust systems;

[0050] The feeding assembly 2 includes fixed support members 201 arranged side by side on the corresponding support frame. The fixed support members 201 are driven by the corresponding driving mechanism 202 to circulate past one side of the feeding end of the spraying mechanism 1. The fixed support members 201 are respectively provided with openings for supporting steel bars upwards, and magnet members 203 for adsorbing and fixing the steel bars are fixedly connected at the openings;

[0051] The feeding guiding mechanism 3 includes a plurality of horizontally supporting and feeding guide rollers 301 rotatably installed side by side at the feeding end of the spraying mechanism 1, and at least one longitudinally limiting cylinder 302 for vibration damping. The inner hole of the longitudinally limiting cylinder 302 is arranged with a coaxial gap with the steel bar. After being conveyed by the fixed support 201, the steel bar passes through the top of the horizontally supporting and feeding guide roller 301 and the inner hole of the longitudinally limiting cylinder 302, and then enters the working station of the spray head 101 for spraying the coating material.

[0052] The driving mechanism 202 adopts a chain conveyor, and the fixed support 201 is fixedly installed on the driving chain of the chain conveyor through a corresponding mounting rod 4.

[0053] The fixed supports 201 of the feeding assembly 2 of the present invention are respectively provided with openings for supporting the steel bars upwards, and magnet members 203 for adsorbing and fixing the steel bars are fixedly connected to the openings. Driven by the driving mechanism 202, the fixed supports 201 circulate past the feeding end side of the spraying mechanism 1, so as to effectively convey the steel bar material to the feeding end side of the spraying mechanism 1 at a uniform speed. Under the guiding and supporting of the horizontally supporting and feeding guide roller 301 of the feeding guiding mechanism 3, the steel bar material passes through the inner hole of the longitudinally limiting cylinder 302 and then enters the working station of the spray head 1 for spraying the coating material.

[0054] Through the support of the opening of the fixed support 201 and the adsorption and fixing method of the magnet member 203, the uniform feeding of the steel bar material is ensured, and the front side of the spraying section of the steel bar material is supported by the horizontally supporting and feeding guide roller 301, so as to effectively prevent excessive sagging deformation of the spraying section of the steel bar material; then, the inner hole of the longitudinally limiting cylinder 302 is used for radial limiting of the steel bar material to control the vibration amplitude generated when the steel bar material leaves the magnet member 203 within a reasonable range.

[0055] Thereby, the structural simplicity of the steel bar feeding mechanism can be effectively and significantly improved to reduce the manufacturing and operation costs of the equipment; and the uniformity of feeding the steel bar material can be greatly improved, and the influence of the vibration amount caused by the improvement of the uniformity can be reduced, so as to effectively and greatly improve the spraying uniformity of the coating material.

[0056] A feeding component 5 is arranged on the front side of the feeding assembly 2. The feeding component 5 corresponds to the position of the feeding assembly 2 and has the same structure as the feeding assembly 2.

[0057] A corresponding loading rack 6 is arranged outside the feeding assembly 5. A plurality of storage chains 7 are horizontally arranged side by side outside the loading rack 6, and the storage chains 7 are synchronously driven by corresponding storage motors 8. A plurality of lifting chains 9 which are arranged in a staggered manner with the storage chains 7 are obliquely upwardly installed on the loading rack 6 on one side of the output end of the storage chains 7. Corresponding clamping plates 901 are fixedly connected to the lifting chains 9 at intervals, and the lifting chains 9 are driven by corresponding lifting motors 10. A plurality of corresponding guide plates 11 are fixedly connected downward side by side on the loading rack 6 at the top of the lifting chains 9. Intermediate transfer rods 13 driven by corresponding driving cylinders 12 are swingably installed in the middle of the guide plates 11 respectively, and corresponding stop rods 14 are fixedly connected to the bottoms of the guide plates 11 respectively. At least one support column 15 is fixedly connected to the side of the feeding assembly 5 where the loading rack 6 is not arranged. A corresponding two-axis motion mechanism 16 is fixedly installed on the support column 15. Cross bars 17 are longitudinally fixedly connected to the moving seats of the two-axis motion mechanism 16 respectively. A plurality of corresponding clamping jaws 18 are fixedly connected downward at intervals on the cross bars 17. Photoelectric sensors 19 for detecting steel bars on the intermediate transfer rods 13 and for detecting steel bars output from the storage chains 7 are fixedly installed on the loading rack 6 respectively.

[0058] A feeding assembly 5 is arranged on the front side of the feeding component 2 of the present invention. The feeding assembly 5 corresponds to the feeding component 2 in position and has the same structure as the feeding component 2. Then a loading rack 6 is arranged outside the feeding assembly 5, and a plurality of storage chains 7 are horizontally arranged side by side outside the loading rack 6. A plurality of lifting chains 9 which are arranged in a staggered manner with the storage chains 7 are obliquely upwardly installed on the loading rack 6 on one side of the output end of the storage chains 7. Driven by the two-axis motion mechanism 16, the position of the clamping jaws 18 is controlled to regularly grab the steel bar materials stored on the stop rods 14 onto the feeding assembly 5. The steel bar materials enter the feeding component 2 under the transmission of the feeding assembly 5 for the next transmission and spraying work.

[0059] During the feeding process, the storage chain 7 is started to transport the steel bars arranged side by side on the storage chain 7 to the position of the lifting chain 9. After the photoelectric sensor for detecting the steel bars outputted from the storage chain 7 detects the output of the steel bar material, the storage chain 7 stops and the lifting chain 9 is started to lift the steel bar material to the position where it falls into the transfer rod 13. After the steel bars on the blocking rod 14 are grabbed away, the driving cylinder 12 drives the transfer rod 13 to swing down, so that the steel bar material on the transfer rod 13 falls onto the blocking rod 14, and then the storage chain 7 and other components are started again to store the single steel bar material again at the position of the transfer rod 13. This effectively ensures that the materials are fed one by one as needed to ensure the continuous and coherent progress of the steel bar spraying operation, thereby effectively assisting in improving the spraying effect of the steel bar material of the present invention.

[0060] A discharging assembly 20 corresponding to the position of the feeding assembly 2 and having the same structure as the feeding assembly 2 is provided on one side of the discharging end of the spraying mechanism 1; the spraying mechanism 1, the feeding assembly 2, the feeding guide mechanism 3, and the discharging assembly 20 are respectively fixed to the corresponding container body. Therefore, the spraying mechanism 1, the feeding assembly 2, the feeding guide mechanism 3, and the discharging assembly 20 of the present invention can be transported as a whole to the corresponding site for spraying processing operations, thereby effectively improving the adaptability of the present invention.

[0061] A discharge mechanism 21 is provided on one side of the discharge end of the discharge component 20, and the discharge mechanism 21 includes a discharge frame 2101, and a plurality of output rollers 2102 rotatably installed side by side on the discharge frame 2101, and the output rollers 2102 are connected to the output shaft ends of the corresponding discharge motors 2103 through chain transmission; a plurality of corresponding discharge rods 2104 are provided between the output rollers 2102, and the outer ends of the discharge rods 2104 are respectively fixed to the corresponding rotating shafts 2105, and at least one of the discharge rods 2104 is driven to swing by the corresponding discharge cylinder 2106.

[0062] A plurality of corresponding H-shaped finished product storage members 22 are arranged side by side on the outer side of the unloading rack 2101 , and arc-shaped storage iron chains 23 are respectively arranged downward at the upper ends of the H-shaped finished product storage members 22 .

[0063] On one side of the discharge end of the discharge assembly 20 of the present invention, a blanking mechanism 21 is provided. The blanking mechanism 21 includes a blanking frame 2101 and a plurality of output rollers 2102 rotatably installed side by side on the blanking frame 2101. The output rollers 2102 are used to output the sprayed steel bar materials. Then, the blanking cylinder 2106 is used to swing-drive the blanking rod 2104 to obliquely export the steel bar materials on the output rollers 2102 outward and make them fall into the storage iron chain 23 of the H-shaped finished product storage member 22, so as to conveniently collect the sprayed steel bar materials by blanking.

[0064] A corresponding guide rod 24 is movably clamped at the top of the blanking rod 2104. A counterweight 2401 is fixedly connected to the outer end of the guide rod 24. A corresponding trapezoidal chute 25 is provided on the top end surface of the blanking rod 2104. A guide block 2402 that is inserted into the trapezoidal chute 25 is provided at the end of the guide rod 24; when the blanking rod 2104 swings down to the in-place position, the inner end of the blanking rod 2104 is inclined downward, and the guide rod 24 resets; when the blanking rod 2104 swings up for blanking, the guide rod 24 moves downward until the guide block 2402 is clamped at the end of the trapezoidal chute 25 to increase the guiding stroke.

[0065] When the blanking rod 2104 of the present invention swings down to the in-place position, the inner end of the blanking rod 2104 is inclined downward to ensure the reset of the guide rod 24; when blanking is required, the blanking rod 2104 is controlled to swing up. At this time, the guide rod 24 can move downward until the guide block 2402 is clamped at the end of the trapezoidal chute 25, thereby increasing the guiding stroke to ensure that the sprayed steel bar materials do not collide excessively with the storage iron chain 23 or other materials stored on the storage iron chain 23 during blanking, so as to prevent excessive damage to the surface of the sprayed steel bar materials.

[0066] A corresponding damping mechanism is provided inside the longitudinal limiting cylinder 302. A vibration sensor 27 for detecting the vibration amount of the horizontal material supporting and guiding roller 301 is fixedly installed on the mounting seat of the horizontal material supporting and guiding roller 301 located in front of the longitudinal limiting cylinder 302; when the vibration sensor 27 detects that the vibration amount formed by the rotation of the horizontal material supporting and guiding roller 301 is greater than the set value V1, the damping mechanism starts to perform damping operation on the steel bars.

[0067] The vibration damping mechanism includes a vibration damping cavity 2601 disposed around the inner hole of the longitudinal limiting cylinder 302. A driving cavity 2602 is provided in the longitudinal limiting cylinder 302 outside the vibration damping cavity. A number of corresponding damping particles 2603 for vibration damping are filled in the vibration damping cavity 2601. The driving cavity 2602 is connected to an external air compressor through a corresponding air filling pipe 28, and a pressure relief valve 29 is connected to the air filling pipe 28. A number of corresponding connecting pipes 2604 are arranged at intervals in the vibration damping cavity 2601. The inner ends of the connecting pipes 2604 penetrate into the inner hole of the longitudinal limiting cylinder 302. Corresponding mounting pistons 2605 are movably installed in the connecting pipes 2604 respectively. Corresponding support balls 2606 are respectively installed on the inner end faces of the mounting pistons 2605 in a rolling manner. Corresponding fixing rods 2607 are respectively fixed in the connecting pipes 2604 outside the mounting pistons 2605. Corresponding limiting springs 2608 are respectively fixedly connected between the fixing rods 2607 and the mounting pistons 2605. When the vibration sensor 27 detects that the vibration amount formed by the rotation of the transverse material supporting roller 301 is greater than a set value V1, the external air compressor injects high-pressure gas into the driving cavity 2602 to drive each mounting piston 2605 to move towards the inner hole side of the longitudinal limiting cylinder 302, so that each support ball 2606 abuts against the surface of the steel bar respectively, and the vibration amount of the steel bar is transmitted to the longitudinal limiting cylinder 302, and effective vibration damping is carried out under the friction energy consumption of the damping particles 2603 for vibration damping. When the vibration sensor 27 detects that the vibration amount formed by the rotation of the transverse material supporting roller 301 is less than a set value V2, the pressure relief valve 29 is opened to relieve pressure, and the mounting piston 2605 is reset under the drive of the limiting spring 2608.

[0068] A vibration damping mechanism is provided in the longitudinal limiting cylinder 302 of the present invention. When the vibration sensor 27 detects that the vibration amount formed by the rotation of the transverse material supporting roller 301 is greater than the set value V1, it can be judged that the steel bar material is in a large vibration state at this time. At this time, the external air compressor is controlled to inject high-pressure gas into the driving cavity 2602 to drive each mounting piston 2605 to move towards the inner hole side of the longitudinal limiting cylinder 302, so that each support ball 2606 abuts against the surface of the steel bar respectively, and the vibration amount of the steel bar is transmitted to the longitudinal limiting cylinder 302, and effective vibration damping is carried out under the friction energy consumption of the damping particles 2603 for vibration damping. When the vibration sensor 27 detects that the vibration amount formed by the rotation of the transverse material supporting roller 301 is less than the set value V2, the pressure relief valve 29 is controlled to open and relieve pressure, and the mounting piston 2605 can be reset under the drive of the limiting spring 2608. Thus, on the premise of not affecting the uniform conveying of the steel bar material and reducing the wear amount between the support balls 2606 and the steel bar material, the vibration amount of the steel bar material can be effectively and practically controlled within a lower range, so as to further greatly improve the spraying uniformity of the coating material.

[0069] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
