Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of bar processing equipment, and relates to a counting device for the head of a bar for fixed length. Background Technology
[0002] In the metallurgical industry, the accuracy of counting the number of steel bars after the steel bar production line is crucial. Most existing methods for counting steel bars involve setting up a counter above the conveyor belt to count the steel bars being transported on the chain conveyor belt. However, sometimes two steel bars are stacked together on the conveyor belt, or multiple steel bars are too close together, which can affect the accuracy of the counting. This results in inaccurate counting of the finished bundles of steel bars, affecting product quality. Utility Model Content
[0003] The purpose of this invention is to address the problem of inaccurate counting in existing bar counting devices in the background art by providing a counting device for the head of a bar in fixed length.
[0004] Therefore, the present invention adopts the following technical solution:
[0005] A counting device for the length-fixing head of bar stock includes a chain conveyor belt. A baffle is provided above the chain conveyor belt, the baffle being arranged along the width direction of the chain conveyor belt, with a gap formed between the bottom of the baffle and the top of the chain conveyor belt. A first electrically operated telescopic rod is provided on one side of the chain conveyor belt along its width direction, and a second electrically operated telescopic rod corresponding to the first electrically operated telescopic rod is provided on the other side. A first limiting plate is provided at the top of the first electrically operated telescopic rod, and a first limiting plate is provided at the top of the second electrically operated telescopic rod. The first electrically operated telescopic rod is connected to a controller, which is connected to both the second electrically operated telescopic rod and the chain conveyor belt. A counter is also provided above the chain conveyor belt. Further, the first electrically operated telescopic rod is vertically arranged.
[0006] Furthermore, the second electric telescopic rod and the first electric telescopic rod are arranged parallel to each other.
[0007] Furthermore, the first limiting plate and the second limiting plate are arranged coplanarly with the baffle.
[0008] Furthermore, a support is provided below the chain conveyor belt, and the first and second electric telescopic rods are fixedly installed on the support.
[0009] The advantages of the new design are: the baffle and the limiting plate prevent the bars on the chain conveyor belt from stacking together by the baffle, and the limiting plate separates the bars on the chain conveyor belt by a certain distance to improve the accuracy of bar counting. The structure is simple and the method of use is convenient. Attached Figure Description

[0014] The present invention will now be described in detail with reference to the accompanying drawings:
[0015] like Figure 1 As shown, a counting device for the head of a bar stock includes a chain conveyor belt 1. The chain conveyor belt 1 can be a conventional chain conveyor belt for transporting bar stock. The bar stock is placed on the chain conveyor belt 1 along its width direction for transport. The length of the bar stock is greater than the width of the chain conveyor belt 1. A counter 2 is also provided above the chain conveyor belt 1. When the bar stock moves on the chain conveyor belt 1 and passes under the counter 2, it can be recorded by the counter 2. The counter 2 is a conventional counter for bar stock statistics. A baffle 3 is provided above the chain conveyor belt 1. The baffle 3 is vertically arranged along the width direction of the chain conveyor belt 1. The bottom of the baffle 3 forms a gap 4 with the top of the chain conveyor belt 1. The height of the gap 4 is adapted to the diameter of the bar stock, which can ensure that the bar stock passes through the gap 4 on the chain conveyor belt 1. The baffle 3 can be installed above the chain conveyor belt 1 by a fixing frame 11. The height can also be adjusted by placing a pad at the bottom of the fixing frame 11 to accommodate bars of different diameters.
[0016] A first electrically operated telescopic rod 5 is vertically arranged on one side of the chain conveyor belt 1, and a second electrically operated telescopic rod 6 corresponding to the first electrically operated telescopic rod 5 is arranged on the other side. The second electrically operated telescopic rod 6 is parallel to the first electrically operated telescopic rod 5. A first limiting plate 7 is provided at the top of the first electrically operated telescopic rod 5, and a second limiting plate 8 is provided at the top of the second electrically operated telescopic rod 6. The first limiting plate 7 and the second limiting plate 8 are coplanar with the baffle 2. The first limiting plate 7 and the second limiting plate 8 can move up and down in the vertical direction of the first electrically operated telescopic rod 5 and the second electrically operated telescopic rod 6. When the top of the first limiting plate 7 and the second limiting plate 8 are above the chain conveyor belt 1, they can block the bar being transported above the chain conveyor belt 1, causing it to be separated from the adjacent bar in front, and accurately counted by the counter 2. To ensure the first electrically operated telescopic rod 6 is in operation, the first limiting plate 7 and the second limiting plate 8 can be moved up and down in the vertical direction. The first electric telescopic rod 5 and the second electric telescopic rod 6 extend and retract synchronously. The first electric telescopic rod 5 is connected to a controller 9, which is connected to the second electric telescopic rod 6 and the chain conveyor belt 1 respectively. A bracket 10 is provided below the chain conveyor belt 1. The first electric telescopic rod 5 and the second electric telescopic rod 6 are both fixedly installed on the bracket 10. The controller 9 can control the extension and retraction frequency of the first electric telescopic rod 5 and the second electric telescopic rod 6 according to the running speed of the chain conveyor belt 1. When the first limit plate 7 and the second limit plate 8 simultaneously block multiple rods, after the first limit plate 7 and the second limit plate 8 descend and move through the gap 4 against the first limit plate 7 and the second limit plate 8, the first limit plate 7 and the second limit plate 8 can be quickly controlled to rise to quickly block the adjacent rods, preventing the adjacent rods from not being able to be pulled apart and affecting the accuracy of counting.
[0017] The method of using this utility model is as follows:
[0018] The produced bars are transported via a chain conveyor belt 1. When the bar reaches the gap 4 below the baffle 3, the first limiting plate 7 and the second limiting plate 8 rise to temporarily block the bar's movement, thus creating distance between the bar and adjacent bars. Then, the first limiting plate 7 and the second limiting plate 8 descend, allowing the blocked bar to continue moving through the gap 4 below the baffle 3. If there are stacked bars above the bar as it passes through the gap 4, the baffle 3 will cause the stacked bars to fall and be counted by the counter 2. After the bar passes through the gap, the first limiting plate 7 and the second limiting plate 8... The position plate 8 rises rapidly, and under the action of the controller 9, the moving speed of the chain conveyor belt 1 is matched with the lifting speed of the first electric telescopic rod 5 and the second electric telescopic rod 6 (that is, the first limit plate 7 and the second limit plate 8 descend, and when the distance the bar on the chain conveyor belt 1 moves reaches the diameter of the bar, the first limit plate 7 and the second limit plate 8 rise rapidly, and after a certain interval, the first limit plate 7 and the second limit plate 8 descend again), blocking the adjacent bars on the rear side. This device can effectively prevent the bars on the chain conveyor belt 1 from stacking or adjacent bars from being too close together, which would lead to counting errors and affect the accuracy of bar counting.
