Description

Technical Field

[0001] This utility model relates to a spraying mechanism, specifically a spraying mechanism for a steel bar surface coating spraying device, which can convey steel bar materials at a uniform speed to ensure the uniformity of the steel bar surface coating. Background Technology

[0002] In some special working conditions, steel bars used require coating spraying to ensure the service life of the steel bar materials under special working conditions.

[0003] Existing rebar surface coating equipment generally includes a spraying mechanism for spraying coating materials, as well as a loading mechanism and a unloading mechanism for loading and unloading the rebar materials. The loading mechanism loads the rebar materials one by one to the spraying mechanism for coating, and the unloading mechanism unloads and collects the coated rebar materials.

[0004] Existing steel bar surface coating spraying equipment generally includes a feeding component and a discharging component for conveying incoming materials, as well as a spraying component located between the feeding component and the discharging component. Because the steel bar material is prone to deformation during the conveying process of the feeding component and the discharging component, the conveying speed often fails to meet the design requirements, resulting in the coating material spraying uniformity failing to meet the design requirements, which is quite troublesome.

[0005] Therefore, the research objective of this utility model is to design a spraying mechanism for a steel reinforcement surface coating spraying device that can effectively ensure the uniformity of steel reinforcement material conveying speed, thereby effectively ensuring the uniformity of coating material spraying. Summary of the Invention

[0006] In view of the technical problems existing in the prior art, the present invention provides a spraying mechanism for a steel bar surface coating spraying equipment, which can effectively solve the technical problems existing in the prior art.

[0007] The technical solution of this utility model is:

[0008] A spraying mechanism for a steel bar surface coating spraying equipment, comprising:

[0009] A spraying assembly, comprising at least one nozzle, for spraying a corresponding coating material onto the surface of a reinforcing steel material;

[0010] The feeding assembly includes fixed support members arranged side by side on corresponding support frames. The fixed support members circulate through one side of the feeding end of the spraying assembly under the drive of the corresponding drive mechanism. The fixed support members are provided with openings for supporting steel bars facing upwards. Magnets for adsorbing and fixing steel bars are fixed to the openings respectively.

[0011] The discharge component is located on one side of the discharge end of the spraying component. The discharge component is positioned corresponding to the feeding component and has the same structure as the feeding component.

[0012] The spraying mechanism also includes a container body, and the spraying assembly, feeding assembly, and discharging assembly are respectively fixedly installed inside the container body.

[0013] The spraying assembly has several transverse guide rollers for supporting the reinforcing bars and at least one longitudinal limiting cylinder for vibration damping installed side by side on one side of the feed end. The inner hole of the longitudinal limiting cylinder is coaxially spaced with the reinforcing bars conveyed by the feed assembly. The reinforcing bars are conveyed by the fixed support and pass through the top of the transverse guide rollers and the inner hole of the longitudinal limiting cylinder before entering the station of the spray head for coating material spraying.

[0014] The drive mechanism is a chain conveyor, and the fixed support is fixedly installed on the drive chain of the chain conveyor by corresponding mounting rods.

[0015] The longitudinal limiting cylinder is equipped with a corresponding vibration damping mechanism. A vibration sensor for detecting the vibration of the transverse material guide roller is fixedly installed on the mounting seat of the transverse material guide roller located in front of the longitudinal limiting cylinder. When the vibration sensor detects that the vibration generated by the rotation of the transverse material guide roller is greater than the set value V1, the vibration damping mechanism is activated to perform vibration damping operation on the reinforcing bar.

[0016] The vibration damping mechanism includes a vibration damping cavity disposed around the inner hole of the longitudinal limiting cylinder. A driving cavity is disposed inside the longitudinal limiting cylinder surrounding the vibration damping cavity. The vibration damping cavity is filled with a number of corresponding damping particles. The driving cavity is connected to an external air compressor through a corresponding air inlet pipe, and a pressure relief valve is connected to the air inlet pipe. Several corresponding connecting pipes are arranged at intervals inside the vibration damping cavity. The inner end of the connecting pipe extends through the inner hole of the longitudinal limiting cylinder. A corresponding mounting piston is movably installed in each connecting pipe. A corresponding support ball is rolled on the inner end face of each mounting piston. A corresponding fixing rod is fixedly connected in the connecting pipe outside the mounting piston. A corresponding limiting spring is fixedly connected between the fixing rod and the mounting piston.

[0017] There are three nozzles, which are arranged at equal angles. Each nozzle has a residual material collection hopper on the outside of its discharge end. The residual material collection hopper is connected to the air inlet of the corresponding extraction system.

[0018] Advantages of this utility model:

[0019] 1) The fixed support members of the feeding assembly of this utility model are respectively provided with upward-facing openings for supporting reinforcing bars, and magnets for adsorbing and fixing the reinforcing bars are fixed to each opening. Under the drive of the driving mechanism, the fixed support members circulate through one side of the feeding end of the spraying assembly, thereby effectively conveying the reinforcing bar material to the feeding end of the spraying assembly at a uniform speed. By using the opening support of the fixed support members and the adsorption and fixing method of the magnets, a stable support against deformation is formed for the reinforcing bar material, ensuring the uniform conveying of the reinforcing bar material, thereby effectively ensuring the uniformity of the coating material spraying.

[0020] 2) This utility model also includes a container body, and the spraying component, feeding component and discharging component are respectively fixedly installed in the container body. Therefore, the spraying component, feeding component and discharging component of this utility model can be transported as a whole to the corresponding site for spraying processing, thereby effectively improving the adaptability of this utility model.

[0021] 3) The spraying assembly of this utility model has several transverse material guide rollers for supporting the reinforcing bars and at least one longitudinal limiting cylinder for vibration damping installed side by side on one side of the feeding end. The inner hole of the longitudinal limiting cylinder is coaxially spaced with the reinforcing bars conveyed by the feeding assembly. The transverse material guide rollers support the front side of the spraying section of the reinforcing bar material, thereby effectively preventing excessive sagging deformation of the spraying section of the reinforcing bar material. Then, the inner hole of the longitudinal limiting cylinder radially limits the reinforcing bar material to control the vibration amplitude generated when the reinforcing bar material leaves the magnet within a reasonable range, thereby further improving the uniformity of the coating material spraying.

[0022] 4) The longitudinal limiting cylinder of this utility model is equipped with a vibration damping mechanism. When the vibration sensor detects that the vibration generated by the rotation of the transverse material guide roller is greater than the set value V1, it can be determined that the steel reinforcement material is under significant vibration. At this time, the external air compressor is controlled to inject high-pressure gas into the drive chamber to drive each mounting piston to move towards the inner hole of the longitudinal limiting cylinder, so that each support ball abuts against the surface of the steel reinforcement, thereby transmitting the vibration of the steel reinforcement to the longitudinal limiting cylinder. The vibration is effectively damped by the frictional energy dissipation of the damping particles. When the vibration sensor detects that the vibration generated by the rotation of the transverse material guide roller is less than the set value V2, the pressure relief valve is controlled to open and release pressure, so that the mounting piston is reset under the drive of the limiting spring. Thus, without affecting the uniform conveying of the steel reinforcement material and reducing the wear of the support balls and the steel reinforcement material, the vibration of the steel reinforcement material is effectively controlled within a low range, thereby further improving the uniformity of the coating material spraying.

Detailed Implementation

[0031] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0032] refer to Figure 1-7 A spraying mechanism for a steel bar surface coating spraying equipment, comprising:

[0033] The spraying assembly 1 includes at least one nozzle 10101 for spraying a corresponding coating material onto the surface of the reinforcing steel material;

[0034] The feeding assembly 2 includes fixed support members 202 arranged side by side on the corresponding support frame 201. The fixed support members 202 are driven by the corresponding driving mechanism 203 and circulate through the feeding end side of the spraying assembly 1. The fixed support members 202 are respectively provided with openings for supporting steel bars facing upwards. Magnets 204 for adsorbing and fixing steel bars are respectively fixed to the openings.

[0035] The discharge component 3 is disposed on one side of the discharge end of the spraying component 1. The discharge component 3 is positioned corresponding to the feeding component 2 and has the same structure as the feeding component 2.

[0036] The feeding assembly 2 of this invention has upward-facing openings for supporting reinforcing bars on its fixed support members 202. Magnets 204 for adsorbing and fixing the reinforcing bars are fixed to these openings. Driven by the driving mechanism 203, the fixed support members 202 circulate through the feeding end of the spraying assembly 1, effectively conveying the reinforcing bar material uniformly to the feeding end of the spraying assembly 1. The openings of the fixed support members 202, combined with the adsorption and fixing by the magnets 204, provide a stable and deformation-resistant support for the reinforcing bar material, ensuring uniform conveying of the material and effectively guaranteeing the uniformity of the coating material spraying.

[0037] The spraying mechanism also includes a container body 4, and the spraying component 1, the feeding component 2, and the discharging component 3 are respectively fixedly installed inside the container body 4. By using the container body 4, the spraying component 1, the feeding component 2, and the discharging component 3 of this invention can be transported as a whole to the corresponding site for spraying operations, thereby effectively improving the adaptability of this invention.

[0038] The spraying assembly 1 has several transverse material guide rollers 5 for supporting the reinforcing bars and at least one longitudinal limiting cylinder 6 for vibration damping installed side by side on one side of the feeding end. The inner hole of the longitudinal limiting cylinder 6 is coaxially spaced with the reinforcing bars conveyed by the feeding assembly 2. The reinforcing bars are conveyed by the fixed support 202, pass through the top of the transverse material guide rollers 5 and the inner hole of the longitudinal limiting cylinder 6, and then enter the station of the spray head 101 for coating material spraying.

[0039] The transverse guide roller 5 supports the front side of the spraying section of the steel reinforcement material, thereby effectively preventing excessive sagging deformation of the spraying section of the steel reinforcement material; then the longitudinal limiting cylinder 6 radially limits the steel reinforcement material to control the vibration amplitude generated when the steel reinforcement material leaves the magnet 204 within a reasonable range, thereby further improving the uniformity of the coating material spraying.

[0040] The drive mechanism 203 is a chain conveyor, and the fixed support 202 is fixedly installed on the drive chain of the chain conveyor by corresponding mounting rods 205.

[0041] The longitudinal limiting cylinder 6 is equipped with a corresponding vibration damping mechanism 7. A vibration sensor 8 for detecting the vibration of the transverse material guide roller 5 is fixedly installed on the mounting seat of the transverse material guide roller 5 located in front of the longitudinal limiting cylinder 6. When the vibration sensor 8 detects that the vibration generated by the rotation of the transverse material guide roller 5 is greater than the set value V1, the vibration damping mechanism 7 is activated to perform vibration damping operation on the steel bar.

[0042] The vibration damping mechanism 7 includes a vibration damping cavity 701 disposed around the inner hole of the longitudinal limiting cylinder 6. A driving cavity 702 is disposed inside the longitudinal limiting cylinder 6 surrounding the vibration damping cavity 701. The vibration damping cavity 701 is filled with a plurality of corresponding damping particles 703. The driving cavity 702 is connected to an external air compressor through a corresponding air inlet pipe 9. A pressure relief valve 10 is connected to the air inlet pipe 9. A plurality of corresponding connecting pipes 704 are arranged at intervals inside the vibration damping cavity 701. The inner end of the connecting pipe 704 extends through the inner hole of the longitudinal limiting cylinder 6. A corresponding mounting piston 705 is movably installed in each connecting pipe 704. A corresponding support ball 706 is rolled on the inner end face of each mounting piston 705. A corresponding fixing rod 707 is fixedly connected to each connecting pipe 704 outside the mounting piston 705. A corresponding limiting spring 708 is fixedly connected between the fixing rod 707 and the mounting piston 705.

[0043] The longitudinal limiting cylinder 6 of this utility model is equipped with a vibration damping mechanism 7. When the vibration sensor 8 detects that the vibration generated by the rotation of the transverse material guide roller 5 is greater than the set value V1, it can be determined that the steel bar material is under a large vibration state. At this time, the external air compressor is controlled to inject high-pressure gas into the drive chamber 702 to drive each mounting piston 705 to move toward the inner hole of the longitudinal limiting cylinder 6, so that each support ball 706 abuts against the surface of the steel bar to transmit the vibration of the steel bar to the longitudinal limiting cylinder 6. The vibration is effectively damped by the frictional energy dissipation of the damping particles 703. When the vibration sensor 8 detects that the vibration generated by the rotation of the transverse material guide roller 5 is less than the set value V2, the pressure relief valve 10 is controlled to open to release pressure, so that the mounting piston 705 is reset under the drive of the limiting spring 708. This effectively controls the vibration of the steel reinforcement material within a low range without affecting the uniform conveying of the steel reinforcement material and reducing the wear of the support ball bearings 706 and the steel reinforcement material, thereby significantly improving the uniformity of the coating material spraying.

[0044] In this embodiment, there are three nozzles 10101, which are arranged at equal angles of 120°. Each of the three nozzles 10101 has a residual material collection hopper 102 on the outside of its discharge end. The residual material collection hopper 102 is connected to the air inlet of the corresponding extraction system.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
