Description

Technical Field

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

[0002] For automatic welding devices for steel mesh, steel bar screening devices are often used to separate the steel bars to be welded from the storage area one by one, and then drop them into the welding station. Existing steel bar screening devices are mainly divided into two categories: one is a screening device that directly screens the steel bars, and the other is a screening device with a primary storage device and a feeding mechanism. When directly screening and separating materials, if the amount of steel bars in the screening area is too large, it can easily cause material jamming between the screening turntable and the outer arc-shaped baffle. Adding a storage device and a feeding mechanism can solve the problem of material jamming between the screening turntable and the arc-shaped baffle when the amount of steel bars in the screening area is too large. However, during the feeding process, the steel bars may also be attracted off-center by the magnetic turntable, no longer parallel to the rotation axis of the magnetic turntable, resulting in misalignment of the steel bars in the screening area, or even preventing them from entering the screening turntable, especially for some shorter transverse steel bars, where the misalignment is more severe. Furthermore, when the magnetic turntable transports steel bars, it magnetizes the steel bars, causing them to attract each other in the buffer zone. This increases the frictional resistance of the steel bars as they slide down, preventing them from falling smoothly into the screening turntable. Utility Model Content

[0003] 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 with a simple structure that helps to prevent steel bars from being attracted and magnetized, and avoids steel bars from being unable to enter the screening turntable smoothly.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A steel bar screening device includes a storage seat, a screening turntable mechanism, and a feeding turntable mechanism for conveying steel bars from the storage seat to the screening turntable mechanism. The feeding turntable mechanism includes a feeding turntable with a plurality of first receiving slots along its circumference. The screening turntable mechanism includes a screening turntable with a plurality of second receiving slots along its circumference.

[0006] As a further improvement to the above technical solution: one side wall of the first receiving groove has a hook-shaped structure.

[0007] As a further improvement to the above technical solution: the other side wall of the first receiving groove is a sloping structure to guide the reinforcing bars into the first receiving groove.

[0008] As a further improvement to the above technical solution: the feeding turntable mechanism is provided with a blocking mechanism for correcting the steel bars conveyed by the feeding turntable mechanism on the side near the screening turntable mechanism, and there is a gap between the blocking mechanism and the feeding turntable mechanism to allow the steel bars to fall.

[0009] As a further improvement to the above technical solution: the blocking mechanism includes a baffle and an adjusting plate slidably disposed on both sides of the baffle.

[0010] As a further improvement to the above technical solution, the feeding turntable mechanism also includes support turntables located on both sides of the feeding turntable along its axial direction.

[0011] As a further improvement to the above technical solution: a feeding buffer seat is provided between the feeding turntable mechanism and the screening turntable mechanism.

[0012] As a further improvement to the above technical solution: the storage seat is provided with a first material shortage detection element, and the feeding buffer seat is provided with a second material shortage detection element.

[0013] As a further improvement to the above technical solution: the storage seat is provided with a first inclined surface for guiding the rolling of the reinforcing bars, and the feeding buffer seat is provided with a second inclined surface for guiding the rolling of the reinforcing bars. The upper side of the second inclined surface is connected to the feeding turntable, and the lower side of the second inclined surface is connected to the screening turntable.

[0014] As a further improvement to the above technical solution: the screening turntable mechanism also includes an arc-shaped stop block disposed on one side of the screening turntable and a third material shortage detection element disposed on the arc-shaped stop block.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] The steel bar screening equipment disclosed in this utility model is equipped with a storage seat and a feeding turntable mechanism. This can avoid the problem of material jamming at the screening turntable when the amount of steel bars is too large during direct screening. Furthermore, the feeding turntable uses multiple first receiving grooves arranged circumferentially to feed small amounts of steel bars to the screening turntable one by one, avoiding the problem of steel bars being attracted and magnetized that is easily caused by using a magnetic turntable. This prevents steel bars entering the screening area from failing to enter the screening turntable smoothly. The structure is simple and reasonable, and has good reliability.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 4As shown, the steel bar screening equipment of this embodiment includes a storage base 1, a screening turntable mechanism 2, and a feeding turntable mechanism 4 for conveying the steel bars 3 in the storage base 1 to the screening turntable mechanism 2. The feeding turntable mechanism 4 includes a feeding turntable 41, which has a plurality of first receiving grooves 411 arranged circumferentially. The screening turntable mechanism 2 includes a screening turntable 21, which has a plurality of second receiving grooves 211 arranged circumferentially. Preferably, the steel bar capacity of the first receiving groove 411 is greater than that of the second receiving groove 211, which is beneficial to improving the feeding efficiency of the feeding turntable 41. Of course, in other embodiments, the steel bar capacity of the two can also be kept the same, which is suitable for steel bars 3 with large size and weight, and where the screening efficiency requirement is not high.

[0029] The steel bar screening equipment of this embodiment is equipped with a storage seat 1 and a feeding turntable mechanism 4. This can avoid the problem of material jamming at the screening turntable 21 when the amount of steel bars 3 is too large during direct screening. In addition, the feeding turntable 41 uses multiple first receiving grooves 411 arranged along the circumference to successively transport a small amount of steel bars 3 to the screening turntable 21. This avoids the problem of steel bars 3 being attracted and magnetized when using a magnetic turntable. It also prevents steel bars 3 entering the screening area from failing to enter the screening turntable 21 smoothly. The structure is simple and reasonable and has good reliability.

[0030] See details Figure 2 Furthermore, in this embodiment, one side wall of the first receiving groove 411 has a hook-shaped structure. Figure 2 Taking the first receiving tank 411 on the left side as an example, the lower side wall has a hook-shaped structure. When the feeding turntable 41 rotates clockwise, it can ensure that the steel bars 3 in the area below the horizontal can also be hooked up, thereby increasing the effective storage space of the first receiving tank 411. The structure is reasonable and effective.

[0031] Furthermore, in this embodiment, the other side wall of the first receiving groove 411 is a sloping structure to guide the reinforcing bar 3 into the first receiving groove 411. Figure 2 The upper sidewall of the first receiving groove 411 on the left side is an upward sloping structure, which makes it easier for the upper steel bar 3 to roll into the interior of the first receiving groove 411. After rotating 180° to the right side, the upper sidewall becomes downward, making it easier for the steel bar 3 to fall out of the first receiving groove 411. The structure is simple and effective.

[0032] See details Figure 1 In this embodiment, the feeding turntable mechanism 4 is provided with a blocking mechanism 5 on the side near the screening turntable mechanism 2 to correct the steel bars 3 conveyed by the feeding turntable mechanism 4. There is a gap between the blocking mechanism 5 and the feeding turntable mechanism 4 to allow the steel bars 3 to fall. The blocking mechanism 5 can reduce the impact force of the steel bars falling freely onto the second inclined surface 62, and can also initially correct the falling steel bars 3, so that the steel bars 3 will not become disordered during the process of falling under their own weight. Moreover, the structure is simple, the cost is low, and the effect is obvious.

[0033] See details Figure 3 The blocking mechanism 5 can be a single plate 51, or it can be as follows: Figure 4 As shown, the blocking mechanism 5 includes a baffle 511 and adjustable plates 512 slidably disposed on both sides of the baffle 511 (for example, through a structure such as a slotted hole, slide rail, or lead screw to achieve sliding adjustment). The width of the blocking mechanism 5 can be adjusted by sliding the adjustable plates 512 to increase the coverage area, making it easy to adapt to steel bars 3 of different lengths. The structure is simple and effective.

[0034] See details Figure 3 and Figure 4 In this embodiment, the feeding turntable mechanism 4 also includes support turntables 42 disposed on both sides of the feeding turntable 41 along the axial direction. The feeding turntable 41 is used to accommodate and transport the reinforcing bars 3, while the support turntables 42 on both sides of the axial direction can provide support for both ends of the reinforcing bars 3, which helps to maintain the state of the reinforcing bars 3.

[0035] Furthermore, in this embodiment, a feeding buffer seat 6 is provided between the feeding turntable mechanism 4 and the screening turntable mechanism 2. The feeding buffer seat 6 can play a buffering and transition role, so that the steel bars 3 conveyed by the feeding turntable 41 can be smoothly transferred to the screening turntable 21.

[0036] Furthermore, in this embodiment, the storage seat 1 is provided with a first material shortage detection element 11, and the feeding buffer seat 6 is provided with a second material shortage detection element 61. By setting the first material shortage detection element 11 and the second material shortage detection element 61, it is easier to control the start and stop of the feeding turntable mechanism 4, and the degree of automation is further improved.

[0037] Furthermore, in this embodiment, the storage seat 1 is provided with a first inclined surface 12 for guiding the rolling of the reinforcing bar 3, so that the reinforcing bar 3 on the storage seat 1 can be automatically fed to the feeding turntable 41. The feeding buffer seat 6 is provided with a second inclined surface 62 for guiding the rolling of the reinforcing bar 3. The upper side of the second inclined surface 62 is connected to the feeding turntable 41, and the lower side of the second inclined surface 62 is connected to the screening turntable 21, so that the reinforcing bar 3 on the feeding buffer seat 6 can be automatically fed to the screening turntable 21.

[0038] Furthermore, in this embodiment, the screening turntable mechanism 2 also includes an arc-shaped stop 22 disposed on one side of the screening turntable 21 and a third material shortage detection element 23 disposed on the arc-shaped stop 22. When the screening turntable 21 rotates, the steel bars 3 on the feeding buffer seat 6 enter each of the second receiving grooves 211 in a corresponding manner. After passing through the arc-shaped stop 22, the steel bars 3 can detach from the second receiving grooves 211 to supply material for the next station. The structure is simple and reliable.

[0039] The working principle of this utility model steel bar screening equipment is as follows:

[0040] The reinforcing bar 3 is stored on the storage seat 1. If the third material shortage detection element 23 detects a material shortage, the feeding turntable 41 and the support turntable 42 rotate. During the rotation, the reinforcing bar 3 is hooked by the first receiving groove 411 arranged on the circumference of the feeding turntable 41, and thus rotates with the feeding turntable 41, and then falls from the gap between the feeding turntable 41 and the blocking mechanism 5 to the lower second inclined surface 62.

[0041] After the steel bar 3 is brought into the screening section, it will roll along the second inclined surface 62 on the feeding buffer seat 6 to the bottom and stick to the screening turntable 21.

[0042] During the rotation of the screening turntable 21, when the second receiving groove 211 rotates to the bottom of the second inclined surface 62, the steel bar 3 that is in close contact with the screening turntable 21 will fall into the second receiving groove 211 by gravity, and thus rotate with the screening turntable 21. In order to achieve the purpose of screening a single steel bar 3, the second receiving groove 211 is set to only accommodate a single steel bar 3, and when the steel bar 3 rotates to the arc-shaped stop 22, there is a small gap between the two, allowing the steel bar 3 to pass smoothly through the area of ​​the arc-shaped stop 22, and the steel bar 3 will not fall out of the groove in this area.

[0043] A third material shortage detection element 23 is set on the arc-shaped stop 22. When the steel bar 3 is detected, it means that the steel bar has successfully fallen into the second receiving tank 211. The screening turntable 21 stops rotating and waits for the material use signal. If the material use signal is received, the screening turntable 21 continues to rotate. After the second receiving tank 211 leaves the area of ​​the arc-shaped stop 22, it can leave the second receiving tank 211 and fall into the next station.

[0044] 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.
