Description

Technical Field

[0001] This utility model relates to the field of rolling equipment, and more specifically, to a rolling mill for producing rebar. Background Technology

[0002] In the production of rebar, rolling is the core process. During rolling, the steel billet is fed into the rolling mill and undergoes multiple rolling and drawing processes to finally become rebar with a diameter of 6–50 mm. The rolling process requires controlling parameters such as rolling temperature, rolling speed, and rolling force to ensure the dimensional accuracy and mechanical properties of the rebar.

[0003] Announcement No. CN219151159U proposes a rolling equipment for rebar. By using a combination of a conveyor belt, a sliding plate, and a cleaning brush, the equipment can improve the straightness of the rebar after it has been rolled, and simultaneously drive the cleaning brush to remove the burrs generated during the rolling process, all without requiring additional power.

[0004] However, during the implementation of this device, the burrs cleaned from the rebar fall directly to the ground, which affects the working environment and requires workers to clean them later, increasing their workload. To address this issue, a rebar rolling mill is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that burrs falling off affect the working environment, requiring workers to clean them later, which increases their workload.

[0006] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a rolling mill for producing rebar, comprising a fixed frame, a conveyor belt inside the fixed frame, a collecting structure at the bottom of the fixed frame, a fixed shell, an observation window fixedly connected to the surface of the fixed shell (the observation window is transparent), a collecting box slidably connected inside the fixed shell, a mounting frame fixedly connected inside the fixed shell, two conveying pipes fixedly connected inside the mounting frame (the two conveying pipes are located on opposite sides inside the fixed shell), an inlet hopper fixedly connected to the surface of each conveying pipe, a guide plate slidably connected inside the fixed shell, a motor mounted inside each conveying pipe, a rotating rod fixedly connected to the surface of the motor, and fan blades fixedly connected to the surface of the rotating rod.

[0007] As a preferred technical solution of this application, the inlet bucket is arranged in a funnel shape and the guide plate is arranged at an angle.

[0008] As a preferred technical solution of this application, a sliding sleeve is fixedly connected to the surface of the guide plate, the interior of the sliding sleeve is slidably connected to the surface of the rotating rod, and a sliding groove is provided inside the sliding sleeve.

[0010] As a preferred technical solution of this application, a limiting rod is fixedly connected to the bottom of the mounting bracket, and the surface of the limiting rod is slidably connected to the inside of the guide plate.

[0011] As a preferred technical solution of this application, a limiting rod is fixedly connected to the bottom of the collection box, and the surface of the limiting rod is slidably connected to the inside of the fixed shell.

[0012] As a preferred technical solution of this application, the fixed shell is fixedly connected to the interior of the mounting frame, the mounting frame is slidably connected to the interior of the moving rod, the bottom of the guide plate is fixedly connected to the driving rod, the driving rod is slidably connected to the interior of the mounting frame, and the sides of the moving rod and the driving rod that are close to each other are serrated.

[0013] As a preferred technical solution of this application, a return spring is fixedly connected inside the mounting frame, and the end of the return spring away from the mounting frame is fixedly connected to the moving rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] 1. By starting the motor, the fan blades rotate, which in turn sucks up the burrs and makes them fall into the interior of the fixed housing, thus preventing the working burrs from scattering everywhere and reducing the workload of the workers by eliminating the need for them to clean the burrs.

[0017] 2. By rotating the rotating rod, the drive rod causes the guide plate to vibrate, which further reduces the amount of burrs adhering to the guide plate and allows the burrs to slide into the inside of the collection box, making it easier to process the burrs later.

By placing the reciprocating screw 19 inside the sliding sleeve 10, the reciprocating screw 19 is prevented from contacting falling burrs, thus reducing the possibility of equipment jamming.

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The bottom of the mounting bracket 6 is fixedly connected to a limiting rod 14. The surface of the limiting rod 14 is slidably connected to the inside of the guide plate 22. The sliding of the guide plate 22 is limited by the setting of the limiting rod 14.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A limiting rod 15 is fixedly connected to the bottom of the collection box 4. The surface of the limiting rod 15 is slidably connected to the inside of the fixed shell 5. The sliding of the collection box 4 is limited by the setting of the limiting rod 15.

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The mounting frame 11 is fixedly connected inside the fixed shell 5. The moving rod 12 is slidably connected inside the mounting frame 11. The bottom of the guide plate 22 is fixedly connected to the drive rod 13. The drive rod 13 is slidably connected to the inside of the mounting frame 11. The sides of the moving rod 12 and the drive rod 13 that are close to each other are serrated.

[0034] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A return spring 18 is fixedly connected inside the mounting frame 11. The end of the return spring 18 away from the mounting frame 11 is fixedly connected to the moving rod 12. The sliding of the moving rod 12 is controlled by the setting of the return spring 18.

[0035] The operation process of the rebar rolling mill provided by this utility model is as follows: In the comparative case, the rebar rolling process is described. During operation, the rebar passes between two pressure rollers, then enters between the upper and lower rollers for pressing, and finally passes through the housing and is discharged. During this process, the rebar first enters between two conveyor belts. Through the use of the upper and lower conveyor belts and the sliding plate, the rebar is straightened and the conveyor belts are rotated. The conveyor belts drive the first roller to rotate (the outer wall of the first roller has teeth, and the inner wall of the conveyor belt has grooves, which mesh). The first roller drives the first gear on it to rotate. The first gear drives the first gear on the second roller to rotate through the first gear-type conveyor belt, thereby rotating the second roller. The second roller grinds the burrs on the rebar.

[0036] When it is necessary to collect the burrs from the grinding of rebar, the operator starts the motor 16. The output end of the motor 16 drives the rotating rod 9 to rotate, which in turn drives the fan blade 17 to rotate. The rotation of the fan blade 17 draws in air, and the conveying pipe 8 is set on both sides inside the fixed shell 5, which draws in air at both ends of the equipment. This allows the falling burrs to enter the fixed shell 5 through the inlet hopper 7 and the conveying pipe 8, where they are collected. Furthermore, the guide pipe on the conveying pipe 8 prevents the fan blade 17 from blowing the burrs on the guide plate 22 again.

[0037] When the rotating rod 9 rotates, it drives the reciprocating lead screw 19 to rotate, and the rotation of the reciprocating lead screw 19 drives the lead screw seat 20. The lead screw seat 20 drives the sliding sleeve 10 to move up and down, and then the guide plate 22 slides up and down, so that the guide plate 22 transports the falling burrs. The guide plate 22 drives the drive rod 13 to move, and the movement of the drive rod 13 causes its surface to press against the surface of the moving rod 12. The moving rod 12 then slides under force. The sliding of the moving rod 12 causes the return spring 18 to deform. Then, under the elastic force of the return spring 18, when the moving rod 12 aligns with the serrations on the drive rod 13, it will strike the drive rod 13. This causes the drive rod 13 to drive the guide plate 22 to vibrate, further reducing the situation where burrs adhere to the guide plate 22, so that the burrs slide into the inside of the collection box 4, which is convenient for later burr processing.
