Description

Technical Field

[0001] The utility model relates to the technical field of bar counting, in particular to an auxiliary device of an automatic steel counting system. Background Art

[0002] In the steel industry, rebar is an important building material, and its production efficiency and quality control are directly related to the economic benefits and market competitiveness of the enterprise. Traditionally, the end of the rebar production line is mostly counted and packaged manually. This process is not only labor-intensive and inefficient, but also very easy to cause counting errors due to human factors, affecting the weight measurement accuracy of the product and customer satisfaction. With the rapid development of industrial automation technology, automatic steel counting systems have gradually replaced manual work and become a key means to improve the automation level of production processes and production efficiency.

[0003] However, in the actual application of the automatic steel counting system, there are still a series of technical challenges. In particular, for the counting of fixed-length rebar, due to its special physical characteristics during transportation, such as easy flipping on the transport roller, slipping during chain transportation, and the accumulation and disturbance caused by the inertia of the steel itself, these have greatly affected the recognition accuracy and stability of the steel counting machine. Specifically, when the rebars form irregular accumulations or interfere with each other on the transport platform, the sensors of the steel counting machine may misjudge or miss, resulting in more or less counting results, which in turn affects the weight measurement of the product and the subsequent sales links, causing unnecessary economic losses and reputation risks to the company.

[0004] Therefore, how to effectively solve the problems of accumulation and disturbance of rebar during transportation and improve the recognition accuracy and reliability of the automatic steel counting system has become a technical problem that steel companies urgently need to solve. Summary of the invention

[0005] The utility model provides a device for breaking up and pressing bars before counting them, which solves the problems of accumulation and disturbance of bars and threaded steel during transportation, thereby reducing the disorder of identification of a steel counting machine and significantly improving the accuracy of steel counting.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is:

[0007] It includes a pressed steel chain located above the rod and parallel to the conveying direction of the rod, the pressed steel chain includes a driving wheel and a driven wheel, and a chain and a chain arm connecting the driving wheel and the driven wheel; wherein the chain arm is located on both sides of the chain, the driven wheel is installed on the chain arm through a pin shaft and screws at both ends of the pin shaft, the driving wheel is connected to a driving motor through a bearing and a transmission shaft, a boss is provided on one side of the driving motor, and a connecting rod is provided between the chain arm and the boss.

[0008] In the above technical solution, a more specific technical solution may further be: a base is provided at the bottom of the driving motor.

[0009] Further, the driving motor and the base are connected by bolts and nuts, and a gasket is provided between the bottom of the driving motor and the nut on the bolt.

[0010] Further, the chain is a toothed chain.

[0011] Further, a spacer sleeve is sleeved outside the pin shaft.

[0012] Further, a coupling is provided at the connection between the driving motor and the transmission shaft.

[0013] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0014] 1. The utility model improves the accuracy of counting steel bars:

[0015] By solving the problems of accumulation and entanglement of ribbed steel bars during transportation, it reduces the situation of disordered recognition by the steel bar counting machine, thus significantly improving the accuracy of counting steel bars, which helps to ensure the accuracy of the specified weight of product packaging and avoid weight measurement deviation caused by counting errors.

[0016] 2. The utility model improves the production efficiency:

[0017] The automatic steel bar counting system replaces the traditional manual steel bar counting method, which not only reduces the labor intensity of workers, but also greatly improves the operation efficiency of the production line. On this basis, the utility model further reduces the time delay and errors caused by manual counting, making the entire production process smoother and more efficient.

[0018] 3. The utility model reduces the enterprise cost:

[0019] Accurate steel bar counting results help enterprises reasonably control product costs and avoid waste of raw materials or overproduction caused by inaccurate counting; at the same time, it reduces customer complaints and returns caused by counting errors, and reduces the after-sales cost of enterprises.

[0020] 4. The utility model drives the chain on the driving wheel and the driven wheel above the steel bars through the driving motor, and separates the stacked steel bars through the chain, solves the problems of accumulation and entanglement of ribbed steel bars during transportation, thereby reducing the situation of disordered recognition by the steel bar counting machine and significantly improving the accuracy of counting steel bars.

Specific embodiments

[0027] The following further details the utility model in conjunction with the accompanying drawings:

[0028] As Figures 1 - 5 shown, a bar steel dispersing and pressing device before steel counting includes a steel pressing chain 2 located above the bar 1, parallel to the conveying direction of the bar 1 and perpendicular to the bar 1. The steel pressing chain 2 includes a driving wheel 2-1 and a driven wheel 2-2, as well as a chain 2-3 connecting the driving wheel 2-1 and the driven wheel 2-2 and a chain arm 2-4. Among them, the chain arm 2-4 is located on both sides of the chain 2-3. The design of the chain arm 2-4 and the chain 2-3 enables the steel pressing chain 2 to act on the bar 1 more evenly during operation. In particular, the structure where the chain arm 2-4 is located on both sides of the chain 2-3 helps to disperse the bar 1 from multiple angles, avoiding entanglement or stacking between the bars 1 and improving the dispersing efficiency. The driven wheel 2-2 is installed on the chain arm 2-4 through a pin shaft 2-5 and screws 2-6 at both ends of the pin shaft 2-5. The driving wheel 2-1 is connected to a driving motor 5 through a bearing 3 and a transmission shaft 4. The driving motor 5 controls the running speed of the steel pressing chain 2 to be consistent with the conveying speed of the bar conveying chain 6. There is a convex platform 7 on one side of the driving motor 5, and a connecting rod 8 is provided between the chain arm 2-4 and the convex platform 7. This connecting rod 8 further enhances the overall stability of the structure.

[0029] The bottom of the driving motor 5 is provided with a base 9, which not only ensures the stability of the driving motor 5 and other devices, but also facilitates installation and layout, effectively saving production space.

[0030] The drive motor 5 is connected to the base 9 by bolts 10 and nuts 11. A gasket 12 is provided between the bottom of the drive motor 5 and the nut 10 on the bolt 10. By adjusting the thickness of the gasket 12, the distance between the pressing steel chain 2 and the bar conveying chain 6 with different diameters and specifications is adjusted, so that the gap between the two is maintained at about 1.6 times the diameter of the bar 1.

[0031] The chain 2-3 is a toothed chain. The tooth profile design of the toothed chain makes the meshing between the chain 2-3 and the sprockets (i.e., the driving sprocket 2-1 and the driven sprocket 2-2) closer and more accurate, reducing the energy loss during the transmission process, thereby improving the transmission efficiency. And because the tooth profile of the toothed chain has higher precision, more accurate transmission can be obtained, reducing the counting error caused by chain slippage or tooth skipping.

[0032] A spacer sleeve 2-7 is sleeved outside the pin shaft 2-5. This spacer sleeve 2-7 can reduce friction and wear, thereby protecting the pin shaft 2-5 and adjacent components.

[0033] A coupling 13 is provided at the connection between the drive motor 5 and the transmission shaft 4. This coupling 13 can efficiently and reliably transmit the rotational motion of the drive motor 5 to the transmission shaft 4, and then drive the entire equipment to operate. This connection is not only stable, but also can ensure the continuous and smooth transmission of power, thereby improving the operation efficiency and stability of the equipment.

[0034] The working process of the present utility model is as follows:

[0035] Along the conveying direction of the bar 1, before the steel counting machine 14, the present utility model 15 is respectively placed on both sides of the bar conveying chain 6 (i.e., both ends of the bar 1), and then the thickness of the gasket 12 is adjusted according to the specifications such as the diameter of the bar 1 so that the distance between the pressing steel chain 2 and the bar conveying chain 6 (the gap between the two) is maintained at about 1.6 times the diameter of the bar 1. The control of the drive motor 5 of the present utility model 15 is adjusted to be synchronized with the control of the bar conveying chain 6, and the running speed and transmission direction of the pressing steel chain 2 are the same as those of the bar conveying chain 6. The single-layer bar 1 passes by incidentally. When the bar 1 accumulates, the thickness of the bar 1 is greater than the passable distance, and it is flattened into a single layer and queued up to pass through here by the present utility model 15, and then is conveyed to the front of the steel counting machine 14 orderly and neatly for counting statistics, thereby improving the accuracy and working efficiency of the steel counting machine 14.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
