A reinforcing bar screening device

Abstract

This utility model discloses a rebar screening device, including a hopper and a discharge turntable assembly. The discharge turntable assembly includes a rotating shaft and a discharge turntable mounted on the rotating shaft. The rebar screening device also includes a material sorting component and a trigger component. The first end of the material sorting component is located at the bottom of the hopper, and the second end is located on one side of the rotating shaft. The trigger component is located on the rotating shaft. When the trigger component rotates, it can squeeze the second end of the material sorting component, causing the first end of the material sorting component to swing upward. In this utility model, the trigger component rotates with the rotating shaft. When the second end of the material sorting component is squeezed, the first end of the material sorting component located at the bottom of the hopper swings upward, thereby lifting the rebar in the hopper upward and bringing it closer to the discharge turntable, making it easier for the rebar in the hopper to be discharged. At the same time, the periodic swinging of the first end of the material sorting component helps to make the disordered rebar above roll relative to each other, thereby arranging them neatly.

Description

Technical Field

[0001] This utility model relates to the field of steel bar processing equipment technology, and in particular to a steel bar screening device. Background Technology

[0002] In automatic rebar mesh welding devices, rebar screening devices are often used to sequentially screen out individual rebars to be welded from the storage area before they fall into the welding station. Existing rebar screening devices are mainly divided into two categories: one is a device that directly screens rebars, and the other is a screening device with a primary storage and feeding mechanism. The storage and feeding mechanisms are designed to address the problem of material jamming between the screening turntable and the arc-shaped baffle if the amount of rebar in the screening area is too large. While adding storage and feeding mechanisms solves the problem of insufficient storage capacity, the storage and feeding mechanisms also have issues during the feeding process. Rebars may be attracted off-center by the magnetic turntable, leading to misalignment after screening or even jamming. This is especially true for short transverse rebars, which are more prone to significant swaying angles and being attracted into the next process, severely impacting subsequent steps. The applicant's earlier application (application number: 202521131135.1) proposed a magnetic sieving device for reinforcing bars. When the reinforcing bars have a large sway angle, one end of the reinforcing bar is located in the positioning groove, while the other end is located outside the positioning groove. This results in one end of the reinforcing bar being lower than the other end, increasing the distance between the middle section of the reinforcing bar and the magnetic sieving element, reducing the magnetic force, and preventing the reinforcing bar from being reliably attracted. The reinforcing bar will fall into the hopper and wait for sieving again. This can effectively prevent the reinforcing bars from swaying and misaligning. Moreover, the overall mechanism is simple and low in cost.

[0003] However, the steel bars inside the silo sometimes fail to fall due to their own weight, and the steel bars located on top of the steel bar pile are also prone to being misplaced, so further improvements are urgently needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a steel bar screening device that is simple in structure, low in cost, facilitates the smooth discharge of steel bars in the silo, and makes the misplaced steel bars neatly arranged.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rebar screening device includes a hopper and a discharge turntable assembly. The discharge turntable assembly includes a rotating shaft and a discharge turntable disposed on the rotating shaft. The rebar screening device also includes a material sorting component and a trigger component. The first end of the material sorting component is disposed at the bottom of the hopper and the second end is disposed on one side of the rotating shaft. The trigger component is disposed on the rotating shaft. When the trigger component rotates, it can squeeze the second end of the material sorting component to make the first end of the material sorting component swing upward.

[0006] As a further improvement to the above technical solution: the rotating shaft is provided with a mounting seat, the trigger is rotatably connected to the mounting seat, a first reset elastic element is connected between the first end of the trigger and the mounting seat, and the second end of the trigger can squeeze the second end of the material handling component when it rotates.

[0007] As a further improvement to the above technical solution: the first reset elastic element is a helical spring, an elastic rope, or an elastic rubber body.

[0008] As a further improvement to the above technical solution: the material handling component is rotatably connected to the hopper, and a second reset elastic component is connected between the first end of the material handling component and the hopper.

[0009] As a further improvement to the above technical solution: the second end of the material feeder is provided with a trigger plate for cooperating with the trigger member, and the width of the trigger plate is greater than the width of the material feeder along the axial direction of the rotating shaft.

[0010] As a further improvement to the above technical solution: the material handling component is provided in two or more parts and is distributed at intervals along the axial direction of the rotating shaft, and the trigger component is provided in a one-to-one correspondence with the material handling component.

[0011] As a further improvement to the above technical solution: the discharge turntable is provided with multiple steel bar receiving slots along the circumferential direction.

[0012] As a further improvement to the above technical solution: the rotating shaft is provided with two or more discharge turntables spaced apart along the axial direction.

[0013] As a further improvement to the above technical solution: the bottom of the silo is arranged at an angle, and the rotating shaft is also provided with steel bars to support the turntable.

[0014] As a further improvement to the above technical solution: the discharge side of the discharge turntable is provided with a discharge support plate, and the discharge support plate is arranged at an angle.

[0015] Compared with the prior art, the advantages of this utility model are: The steel bar screening device disclosed in this utility model uses a rotating shaft to drive a discharge turntable to rotate, thereby screening the steel bars from the hopper and transferring them to the downstream welding station. A trigger element rotates with the shaft; when it presses the second end of the sorting component, the first end of the sorting component at the bottom of the hopper swings upward, lifting the steel bars in the hopper and bringing them closer to the discharge turntable, making it easier for the steel bars to exit the hopper. Simultaneously, the periodic swinging of the first end of the sorting component helps to relatively roll the misaligned steel bars above, thus arranging them neatly. The structure is simple and effective.

[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Figures 1 to 4 This illustration shows an embodiment of the rebar screening device of the present invention. The rebar screening device of this embodiment includes a hopper 1 and a discharge turntable assembly 2. The discharge turntable assembly 2 includes a rotating shaft 21 and a discharge turntable 22 disposed on the rotating shaft 21. The rebar screening device also includes a material handling component 3 and a trigger component 4. The first end of the material handling component 3 is disposed at the bottom of the hopper 1, and the second end is disposed on one side of the rotating shaft 21. The trigger component 4 is disposed on the rotating shaft 21. When the trigger component 4 rotates, it can squeeze the second end of the material handling component 3, causing the first end of the material handling component 3 to swing upward. Preferably, the hopper 1 can be assembled from a side baffle 11, a bottom plate 12, and an end baffle 13; the driving component (e.g., a motor) of the rotating shaft 21 is disposed on the outside of the side baffle 11.

[0026] In this embodiment of the rebar screening device, the rotating shaft 21 drives the discharge turntable 22 to rotate, thereby screening the rebar from the hopper 1 and transferring it to the downstream welding station. The trigger element 4 rotates with the rotating shaft 21. When the second end of the material handling element 3 is squeezed, the first end of the material handling element 3 located at the bottom of the hopper 1 swings upward (specifically as follows). Figure 3 and Figure 4 As shown in the figure, the steel bars in the hopper 1 can be lifted upward and brought closer to the discharge turntable 22, making it easier for the steel bars in the hopper 1 to be discharged. At the same time, the periodic oscillation of the first end of the material handling component 3 helps to make the disordered steel bars above roll relative to each other, thus arranging them neatly. The structure is simple and effective.

[0027] Furthermore, in this embodiment, a mounting base 23 is provided on the rotating shaft 21, and the trigger 4 is rotatably connected to the mounting base 23 (e.g., through a pin, screw, etc.). A first reset elastic element 24 is connected between the first end of the trigger 4 and the mounting base 23. When the second end of the trigger 4 rotates, it can squeeze the second end of the material handling component 3. If the weight of the steel bars in the hopper 1 is too large, causing the second end of the material handling component 3 to be unable to rotate even after being squeezed by the trigger 4, the trigger 4 can rotate around its own rotation center after overcoming the elastic force of the first reset elastic element 24, thereby avoiding the obstruction of the second end of the material handling component 3. This prevents the rotating shaft 21 from failing to rotate normally, thus achieving the purpose of overload protection and avoiding equipment damage. After avoiding the obstruction of the second end of the material handling component 3, the trigger 4 resets under the elastic force of the first reset elastic element 24.

[0028] Preferably, in this embodiment, the first reset elastic element 24 is a helical spring, which has good reliability and low cost. Of course, in other embodiments, the first reset elastic element 24 can also be an elastic rope or an elastic rubber body, as long as it can achieve the reset of the trigger element 4.

[0029] In a preferred embodiment, the feeder 3 is rotatably connected to the hopper 1 (e.g., via a pin, screw, etc.), and a second reset elastic element 31 is connected between the first end of the feeder 3 and the hopper 1. When the trigger 4 disengages from the second end of the feeder 3, the elastic force of the second reset elastic element 31 acts on the first end of the feeder 3, causing it to reset and prepare for the next cycle. Preferably, the second reset elastic element 31 is a helical spring, which offers high reliability and low cost. Of course, in other embodiments, the second reset elastic element 31 can also be an elastic rope or an elastic rubber body, as long as it can achieve the reset of the feeder 3.

[0030] See details Figure 2 In this embodiment, the second end of the material handling component 3 is provided with a trigger plate 32 for cooperating with the trigger component 4. Along the axial direction of the rotating shaft 21, the width of the trigger plate 32 is greater than the width of the material handling component 3. By increasing the width of the trigger plate 32, it can be better squeezed by the trigger component 4, eliminating errors in the processing and assembly process, and further improving reliability.

[0031] In a preferred embodiment, there are two or more material handling components 3, which are spaced apart along the axial direction of the rotating shaft 21, and the triggering component 4 is arranged in a one-to-one correspondence with the material handling component 3. Since the reinforcing bar has a certain length, setting multiple material handling components 3 can better enable the reinforcing bar to move as a whole.

[0032] In a preferred embodiment, the discharge turntable 22 is provided with multiple rebar receiving slots 221 along the circumferential direction. When the discharge turntable 22 rotates, the rebars in the hopper 1 enter the rebar receiving slots 221. When the rebar receiving slots 221 rotate to the discharge side, the rebars fall out of the rebar receiving slots 221. The structure is simple, low in cost, and reliable. Of course, in other embodiments, the discharge turntable 22 can also be a magnetic turntable.

[0033] Furthermore, in this embodiment, the rotating shaft 21 is provided with two or more discharge turntables 22 spaced apart along the axial direction. Since the reinforcing bars have a certain length, providing multiple discharge turntables 22 helps to keep the reinforcing bars as a whole parallel to the rotating shaft 21 and prevents swaying.

[0034] Furthermore, in this embodiment, the bottom of the hopper 1 is arranged at an incline, and a steel bar support turntable 25 is also provided on the rotating shaft 21. The incline arrangement of the bottom of the hopper 1 facilitates the entry of the steel bars in the hopper 1 into the steel bar receiving groove 221 of the discharge turntable 22 under the action of gravity; the steel bar support turntable 25 can provide support for the steel bars in the hopper 1, which is conducive to making the steel bars stacked neatly.

[0035] Furthermore, in this embodiment, the discharge turntable 22 is provided with a discharge support plate 5 on the discharge side, and the discharge support plate 5 is arranged at an angle. When the steel bars in the steel bar receiving groove 221 rotate to the discharge side, they contact the discharge support plate 5, and the discharge turntable 22 continues to rotate, causing the steel bars to detach from the steel bar receiving groove 221 and roll along the discharge support plate 5 to the set position. The structure is simple, the cost is low, and the reliability is good.

[0036] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
