Abstract
Description
Technical Field
[0001] The present application relates to the field of roller conveying technology, and in particular to a conveyor roller for transporting rolled pieces. Background Art
[0002] In the metal processing industry, the conveyor roller of rolled products is a key equipment on the production line, which undertakes the important task of transporting the high-temperature rolled products from the rolling mill to the next process.
[0003] Existing conveyor roller designs often focus on their conveying function, while neglecting the need to dissipate heat during the conveying process. Particularly in continuous, high-intensity production environments, where temperatures often reach hundreds of degrees Celsius, failure to dissipate heat in a timely and effective manner can not only affect the quality of the rolled pieces but can also cause thermal damage to the conveyor rollers themselves, shortening their service life.
[0004] Conveyor rollers have significant shortcomings in heat dissipation. For one thing, some roller designs lack dedicated heat dissipation devices, relying solely on natural cooling or the indoor environment for heat dissipation. This approach has minimal cooling effect in high indoor temperatures or high production intensity, making it difficult to meet actual needs. Furthermore, while some rollers attempt to enhance heat dissipation by introducing indoor circulating air, these methods are often limited by the indoor temperature and have poor heat dissipation effects.
[0005] Furthermore, most existing cooling systems utilize a closed design, lacking direct exchange with the outside environment, resulting in inefficient cooling. This is especially true in summer or high-temperature environments, where indoor air temperatures are already high. Using such cooling systems is ineffective and fails to achieve the desired cooling effect.
[0006] In view of the above problems, a conveyor roller table for transporting rolled pieces is now designed. Utility Model Content
[0007] The embodiment of the present application provides a conveyor roller for transporting rolled pieces, so as to solve the problem of poor heat dissipation effect of the conveyor roller for transporting rolled pieces in the related art.
[0008] In a first aspect, a conveyor roller conveyor for conveying rolled products is provided, comprising:

DETAILED DESCRIPTION
[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0026] The embodiment of the present application provides a conveyor roller for transporting rolled pieces, which can solve the problem of poor heat dissipation effect of the conveyor roller for transporting rolled pieces in the related art.
[0027] See also Figure 1-Figure 3, a conveyor roller for transporting rolled products comprises: a frame 1 and a fixed plate 2 relatively arranged on the frame 1, a plurality of bearing seats 3 are provided on the fixed plate 2, a roller 4 is rotatably arranged between two of the bearing seats 3, and a plurality of the rollers 4 are distributed along the length of the fixed plate 2 to form a roller 12 for conveying the rolled products, a driving member 5 is provided on the fixed plate 2, the driving member 5 is connected to any of the rollers 4 and is used to drive the roller 12 to operate and transport the rolled products; a cooling box 6 is provided between the tops of the two fixed plates 2, a heat dissipation channel 7 for cooling the rolled products is provided inside the cooling box 6, an air supply duct 8 is embedded above the cooling box 6, the bottom of the air supply duct 8 extends into the heat dissipation channel 7, a fan 9 located above the heat dissipation channel 7 is provided inside the air supply duct 8, and the air supply duct 8 is used to transmit outdoor air.
[0028] In terms of conveying, the fixed plates 2 arranged opposite to each other on the frame 1, as well as the bearing blocks 3 and rollers 4 distributed on the fixed plates 2, form a roller table 12 distributed along the length of the fixed plates 2. When the driving member 5 is started and connected with any roller 4, it drives all rollers 4 to rotate synchronously, thereby achieving continuous conveying of the rolled products on the roller table 12.
[0029] The cooling box 6, located between the tops of the two fixed plates 2, and its internal heat dissipation channel 7 play a key role in cooling. An air supply duct 8 is embedded above the cooling box 6, with its bottom extending into the heat dissipation channel 7. A fan 9, located within the air supply duct 8, draws in cool air from the outside and delivers it through the air supply duct 8 into the heat dissipation channel 7. As the rolled material passes through the heat dissipation channel 7 on the roller table 12, the cool air directly contacts the rolled material surface, exchanging heat and effectively reducing its temperature.
[0030] By introducing cold outdoor air as a cooling medium, combined with the forced convection of fan 9, efficient heat dissipation from the rolled material is achieved. This design overcomes the problem of high indoor air temperature and poor heat dissipation, significantly improving the cooling efficiency of the rolled material. Because the rolled material is promptly and effectively cooled during conveyance, thermal damage to equipment caused by high temperatures is avoided, thereby extending the service life of the conveyor roller and its associated equipment.
[0031] By utilizing outdoor cold air for heat dissipation, there is no need to consume additional energy for refrigeration or circulating air treatment, which reduces production costs and energy consumption, while also reducing the impact on the indoor environment, in line with the concept of environmental protection and energy conservation.
[0032] like Figure 2 As shown, in this embodiment, several of the bearing seats 3 are distributed along the length of the fixed plate 2, one end of the roller 4 passes through the bearing seat 3 and extends outward, and a transmission shaft 41 is provided at the outwardly extending end of the roller 4.
[0033] Several bearing seats 3 are evenly distributed along the length of the fixed plate 2, providing stable support for the roller 4. This layout ensures that the roller 4 can remain stable during rotation, reducing vibration and noise.
[0034] One end of each roller 4 extends through its corresponding bearing seat 3. This design allows the roller 4 to rotate freely within the bearing seat 3 while bearing the weight and friction of the workpiece. The other end of the roller 4 extends outward to accommodate a drive shaft 41. Drive shaft 41 is mounted on the outwardly extending end of the roller 4 and connects the roller 4 to the drive member 5.
[0035] Specifically, the driving member 5 includes a mounting frame 51 arranged on the fixed plate 2, a reducer is arranged on the mounting frame 51, a driving motor 52 is arranged on the reducer, the output shaft of the driving motor 52 is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the end of the roller 4 away from the transmission shaft 41; two sprockets 53 are arranged on the other end of the transmission shaft 41, and a chain is wound around the outer sides of two adjacent sprockets 53 on the same side, and several of the chains are staggered front and back.
[0036] The mounting frame 51 provides support for the entire drive system. A reducer is mounted on the mounting frame 51, reducing the output speed of the drive motor 52 and increasing the torque to meet the driving requirements of the roller 4. The output shaft of the drive motor 52 is connected to the input shaft of the reducer. When the drive motor 52 is started, the power generated by it is transmitted to the output shaft through the reducer. The output shaft of the reducer is directly connected to the end of the roller 4 away from the transmission shaft 41, thereby driving the roller 4 to rotate.
[0037] To achieve synchronous rotation of the multiple rollers 4, two sprockets 53 are mounted on the other end of the drive shaft 41. Two adjacent sprockets 53 on the same side are connected by chains, forming a chain drive system. These chains are staggered front to back, ensuring efficient power transfer from one roller 4 to the next, achieving synchronous operation of the entire roller conveyor 12.
[0038] In this embodiment, a protective bin is provided on the fixed plate 2 and is located outside the transmission shaft 41 and the sprocket 53. The protective bin is U-shaped with openings at both ends. A through hole is provided on the protective bin for the transmission shaft 41 to extend.
[0039] In one embodiment, both ends of the heat dissipation channel 7 are open, and exhaust nets are arranged on the cooling box 6 opposite to each other.
[0040] Both ends of the heat dissipation channel 7 are designed to be open, allowing the rolled pieces to freely enter and exit the heat dissipation channel during transportation, while also facilitating the inflow of cold air and the discharge of hot air.
[0041] Inside the air supply duct 8, air is driven by a fan 9 and extends through the bottom of the air supply duct 8 into the heat dissipation channel 7. In the heat dissipation channel 7, the cold air exchanges heat with the rolled workpiece, removes the heat from the rolled workpiece, and is discharged through the exhaust mesh on the cooling box 6 and the openings at both ends of the heat dissipation channel 7.
[0042] As a preferred embodiment, it further includes a main pipeline 10, which is arranged above the air supply pipeline 8, one end of the main pipeline 10 is connected to the outdoors, and the top end of the air supply pipeline 8 is connected to the main pipeline 10.
[0043] The main duct 10 is positioned above the supply ducts 8, creating a more centralized air supply system. One end of the main duct 10 is directly connected to the outside air, allowing fresh air to flow in unimpeded. As outdoor air enters through the main duct 10, it is distributed to the individual supply ducts 8. The top ends of the supply ducts 8 are connected to the main duct 10, ensuring that each supply duct 8 receives sufficient air flow.
[0044] Furthermore, a baffle 11 is provided on the fixed plate 2, and two of the baffles 11 are arranged on both sides above the roller 12; the baffle 11 includes a plurality of fixed bars 111 provided on the fixed plate 2, and the plurality of fixed bars 111 are located between adjacent rollers 4, and a blocking plate 112 is provided between the tops of the plurality of fixed bars 111 on the same side.
[0045] The baffle 112 can be a continuous plate or connected in sections, depending on design and process requirements. The top edge of the baffle 112 is kept a certain distance above the roller table 12 to avoid direct contact with the workpiece. As the workpiece moves on the roller table 12, the baffle 112 prevents it from rolling off or falling off the roller table 12 due to vibration or deviation.
[0046] In another embodiment, a waste slag box is provided inside the frame 1 and is located below the roller conveyor 12 , and a plurality of discharge valves are provided at the bottom of the waste slag box.
[0047] During the rolling process, the friction between the rolled stock and the rollers 4 and the deformation of the rolled stock itself may produce some slag and debris. These slag and debris will fall into the slag box below the roller table 12.
[0048] The slag box has sufficient capacity to store this slag and debris, preventing it from accumulating on the roller conveyor 12 or escaping into the production environment. When the slag in the slag box reaches a certain amount, it can be discharged by operating the discharge valve at the bottom. The discharge valves can be opened individually or simultaneously as needed to control the discharge speed and direction of the slag.
