Description

Technical Field

[0001] This utility model relates to an auxiliary mechanism for a steel bar surface coating spraying equipment, specifically a material feeding mechanism for a steel bar surface coating spraying equipment, which can output the steel bar material after coating is completed while reducing surface damage. 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 coating material nozzles and a rebar feeding mechanism for conveying the rebar material. Several nozzles, arranged at equal angles, uniformly spray the coating material onto the rebar material conveyed past the nozzle stations. Currently, the unloading process of the coated rebar material mainly relies on manual handling, which is often difficult due to the relatively large weight of the rebar. Therefore, automated unloading mechanisms have begun to be developed and put into use. However, because the rebar material entering the coating process is generally quite long, it is relatively prone to bending and deformation, making automated handling difficult; furthermore, the surface coating of the rebar material is easily damaged during automated unloading, making it difficult to effectively implement automated unloading mechanisms.

[0004] Therefore, the research objective of this utility model is to design a feeding mechanism for a steel reinforcement surface coating spraying equipment that can effectively and conveniently automatically transport and unload steel reinforcement materials after coating spraying, and effectively reduce damage to the surface coating of steel reinforcement materials during automatic transport. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a feeding mechanism for a steel bar surface coating spraying equipment, which can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A feeding mechanism for a steel bar surface coating spraying equipment includes:

[0008] A feeding frame, on which at least one row of several corresponding output rollers are rotatably mounted side by side, and the output rollers are connected to the output shaft end of the corresponding feeding motor by chain drive;

[0009] Several feeding rods are respectively arranged between corresponding output rollers, and the outer ends of the feeding rods are respectively fixed to corresponding rotating shafts. At least one feeding rod is driven by a corresponding feeding cylinder to swing.

[0010] The storage mechanism includes several H-shaped product storage components arranged side by side on the outside of the unloading frame. The upper ends of the H-shaped product storage components are respectively provided with deformable bearing components arranged in an arc shape.

[0011] The top of the feeding rod is movably engaged with a corresponding guide rod, and a counterweight is fixed to the outer end of the guide rod. The top surface of the feeding rod is provided with a corresponding trapezoidal groove, and the end of the guide rod is provided with a guide block that engages with the trapezoidal groove. When the feeding rod swings down to its position, the inner end of the feeding rod is tilted downward, and the guide rod is reset under the action of gravity. When the feeding rod swings up to discharge material, the guide rod moves downward until the guide block is engaged with the end of the trapezoidal groove.

[0012] The guide rod and counterweight are made of engineering plastic through a one-piece molding process.

[0013] The output roller is made of engineering plastic, and corresponding baffles are integrally formed and fixed upward on both sides of the output roller.

[0014] The deformable support component is made of iron chain, and its two ends are fixedly welded upwards to the upper sides of the H-shaped product storage component.

[0015] The H-shaped product storage unit is constructed by welding channel steel. A corresponding mounting plate is fixedly welded to the bottom of the H-shaped product storage unit, and the mounting plate is fixedly installed on the workshop floor by corresponding fastening bolts.

[0016] Advantages of this utility model:

[0017] 1) The feeding frame of this utility model has at least one row of several corresponding output rollers mounted side by side for rotation. The output rollers are connected to the output shaft of the corresponding feeding motor via chain drive. During the feeding process, the rotation of the output rollers provides rolling support for the coated steel reinforcement material. After the steel reinforcement material is discharged into position, the piston rod of the feeding cylinder extends to control at least one feeding rod to swing upward. Then, the rotating shaft synchronously drives all the feeding rods to swing upward, thereby pushing and feeding the steel reinforcement material on the output rollers onto the deformable bearing of the storage mechanism. This effectively and conveniently enables automatic handling and feeding of the coated steel reinforcement material, and effectively reduces damage to the surface coating of the steel reinforcement material during automatic handling.

[0018] 2) The top of the feeding rod of this utility model is movably engaged with a corresponding guide rod, and the outer end of the guide rod is fixedly connected with a counterweight. The top surface of the feeding rod is provided with a corresponding trapezoidal groove, and the end of the guide rod is provided with a guide block that engages with the trapezoidal groove. When the feeding rod swings down to its position, the inner end of the feeding rod is tilted downward to ensure that the guide rod can be reset under the action of gravity. When feeding is required, the feeding rod is controlled to swing upward. At this time, the guide rod can move downward until the guide block is engaged with the end of the trapezoidal groove, thereby increasing the guiding stroke. This ensures that the steel reinforcement material after spraying does not collide excessively with the deformable bearing or other steel reinforcement material stored on the deformable bearing during feeding, thereby further preventing excessive damage to the surface coating of the steel reinforcement material after spraying.

[0025] 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:

[0026] refer to Figure 1-5 A material feeding mechanism for a steel bar surface coating spraying equipment, comprising:

[0027] The feeding frame 1 has at least one row of several corresponding output rollers 2 rotatably mounted side by side on the feeding frame 1. The output rollers 2 are connected to the output shaft end of the corresponding feeding motor 3 by chain drive.

[0028] Several feeding rods 4 are respectively arranged between corresponding output rollers 2, and the outer ends of the feeding rods 4 are respectively fixed to corresponding rotating shafts 5. At least one feeding rod 4 is driven by a corresponding feeding cylinder 6 to swing.

[0029] The storage mechanism 7 includes several H-shaped product storage components 701 arranged side by side on the outside of the unloading frame 1. The upper ends of the H-shaped product storage components 701 are respectively provided with deformable bearing components 702 arranged in an arc shape facing downward.

[0030] In the material feeding process of this invention, the output roller 2 rotates to support the coated steel reinforcement material during feeding. After the steel reinforcement material is fed into position, the piston rod of the feeding cylinder 6 extends to control at least one feeding rod 4 to swing upward. Then, the rotating shaft 5 synchronously drives all feeding rods 4 to swing upward, thereby feeding the steel reinforcement material on the output roller 2 onto the deformable bearing member 702 of the storage mechanism 7. This effectively and conveniently enables automatic handling and feeding of the coated steel reinforcement material, and effectively reduces damage to the surface coating of the steel reinforcement material during automatic handling.

[0031] The top of the feeding rod 4 is movably engaged with a corresponding guide rod 8. A counterweight 9 is fixedly connected to the outer end of the guide rod 8. A trapezoidal groove 401 is provided on the top surface of the feeding rod 4. A guide block 801 is provided at the end of the guide rod 8, which engages with the trapezoidal groove 401. When the feeding rod 4 swings down to its position, the inner end of the feeding rod 4 is tilted downward, and the guide rod 8 is reset under the action of gravity. When the feeding rod 4 swings up to discharge material, the guide rod 8 moves downward until the guide block 801 is engaged with the end of the trapezoidal groove 401.

[0032] When the unloading rod 4 is lowered to its position, the inner end of the unloading rod 4 is inclined downward to ensure that the guide rod 8 can be reset under the action of gravity. When unloading is required, the unloading rod 4 is controlled to swing upward. At this time, the guide rod 8 can move downward until the guide block 801 is locked at the end of the trapezoidal slide 401, thereby increasing the guiding stroke. This ensures that the steel reinforcement material after spraying does not collide excessively with the deformable bearing 702 or other steel reinforcement material stored on the deformable bearing 702 during unloading, thereby further preventing excessive damage to the surface coating of the steel reinforcement material after spraying.

[0033] The guide rod 8 and the counterweight 9 are made of engineering plastic through a one-piece molding process. The output roller 2 is made of engineering plastic, and corresponding baffles 201 are integrally molded and fixed upward on both sides of the output roller 2.

[0034] The deformable support member 702 is made of iron chain, and its two ends are fixedly welded upward to the upper sides of the H-shaped product storage member 701.

[0035] The H-shaped product storage component 701 is made of channel steel welded together. A corresponding mounting plate 10 is fixedly welded to the bottom of the H-shaped product storage component 701. The mounting plate 10 is fixedly installed on the workshop floor by corresponding fastening bolts.

[0036] 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.
