Description

Technical Field

[0001] This application relates to the field of idler roller processing equipment technology, and in particular to a grinding and rust removal device for idler roller production. Background Technology

[0002] As a core component of belt conveyors, the surface quality of idlers directly affects the conveyor's operational stability, service life, and conveying efficiency. During the production of idlers, the raw materials (usually steel pipes) are prone to rusting due to environmental humidity, oxidation, and other factors during storage and transportation. At the same time, defects such as burrs and oxide scale may remain on the surface during processing. Therefore, they must undergo grinding and rust removal treatment before proceeding to subsequent processes.

[0003] Currently, the grinding and rust removal devices used in idler roller production have many shortcomings: First, most devices can only grind the outer or inner wall of the idler roller in one direction, requiring multiple clamping operations to complete the comprehensive treatment of the inner and outer walls, which is not only cumbersome to operate, but also significantly reduces production efficiency; Second, the grinding components of existing devices are mostly fixed in position, which cannot be flexibly adjusted according to the diameter and length of idler rollers of different specifications, resulting in poor adaptability and limited grinding range, making it difficult to achieve precise grinding for non-standard sized idler rollers. Utility Model Content

[0004] This utility model addresses the aforementioned problems in the existing technology by providing a grinding and rust removal device for idler roller production.

[0005] The objective of this utility model is mainly achieved through the following solution:

[0006] A grinding and rust removal device for idler roller production includes a support platform, a rotating disk is mounted on the upper surface of the support platform, and the rotating disk is driven to rotate by a first drive component on the support platform. A clamp for vertically clamping raw materials is detachably and fixedly mounted on the upper surface of the rotating disk.

[0007] A support frame is installed on one side of the upper surface of the support platform, and a support plate that can move up and down is installed on one side of the support frame. The support plate can be moved up and down by the telescopic components on the support frame.

[0008] The lower surface of the support plate is equipped with two sets of grinding components, and the grinding components are driven to rotate by the second drive component on the support plate, thereby achieving grinding of the inner and outer walls of the raw material.

[0009] Preferably, the first drive component is mounted on the lower surface of the support platform, and the output end of the first drive component is fixedly connected to the middle of the lower surface of the rotary disk.

[0011] Preferably, a vertically arranged slide rail is installed on the front side of the support frame, and a slider that cooperates with the slide rail is installed on the lower part of the support plate. The telescopic component can drive the support plate and the slider to move up and down along the slide rail.

[0012] Preferably, each grinding assembly includes a support cylinder with a vertically arranged rotating shaft rotatably connected to it. The bottom of the rotating shaft passes through the lower surface of the support cylinder and is detachably and fixedly connected to a grinding head.

[0014] Preferably, the support plate is also equipped with a first tensioning pulley for tensioning the first transmission belt and a second tensioning pulley for tensioning the second transmission belt.

It can be adjusted to grind the inner wall of the roller at the same time or grind the outer wall on both sides of the roller according to the needs.

Detailed Implementation

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0026] like Figure 1 , 2 As shown, this utility model discloses a technical solution for a grinding and rust removal device for idler roller production, including a support platform 1. A rotating disk 2 is installed on the upper surface of the support platform 1, and the rotating disk 2 is driven to rotate by a first drive component 3 on the support platform 1. A clamp 4 for vertically clamping raw materials is detachably and fixedly installed on the upper surface of the rotating disk 2. The first drive component 3 drives the rotating disk 2 and the idler rollers on the clamp 4 to rotate synchronously, providing stable rotational power for the grinding process. The vertical clamping method can effectively prevent the idler rollers from axially shifting during the grinding process and improve clamping stability. In this embodiment, the support platform 1 is welded from Q235 steel plate, and the bottom is supported on the ground by adjustable feet to ensure that the device does not shake during operation. The first drive component 3 is a Siemens servo motor with model number 1FL6064-1AC61-2AA1, with a power of 2.2kW and a speed range of 0-300rpm. The output end of the motor is fixedly connected to the middle of the lower surface of the rotating disk 2 through a coupling. The rotating disk 2 is made of 45# steel.

[0027] A support frame 5 is welded or bolted to the rear side of the upper surface of the support platform 1. A support plate 6 that can move up and down is installed on one side of the support frame 5, and the support plate 6 is moved up and down by the telescopic component 7 on the support frame 5. The support plate 6 is moved up and down by the telescopic component to polish the roller. In this embodiment, the telescopic component 7 is a hydraulic cylinder of model HOB63×500. The cylinder body is fixed to the upper front side of the support frame 5 by bolts, and the end of the piston rod is fixedly connected to the upper surface of the support plate 6 by bolts.

[0028] The lower surface of the support plate 6 is equipped with two sets of grinding components, and the two sets of grinding components are driven to rotate in the same direction by the second drive component 8 on the support plate 6. The two sets of grinding components can be adjusted in position according to grinding requirements, so as to simultaneously extend into the steel pipe to grind the inner wall, or to be located on both sides of the steel pipe to grind the outside. The grinding efficiency and uniformity are improved by the synchronous operation of the two components.

[0029] Specifically, the first drive assembly 3 is bolted to the lower surface of the support platform 1, and the output end of the first drive assembly 3 passes through the bearing on the support platform 1 and is fixedly connected to the middle of the lower surface of the rotary disk 2. This installation method can ensure that the rotary disk is subjected to uniform force and the rotation process is more stable. The clamp 4 adopts a three-jaw chuck (model K11-200), and the fixed end of the three-jaw chuck is coaxially fixedly installed with the upper surface of the rotary disk 2. The three-jaw chuck has the characteristics of high centering accuracy and stable clamping force, which can realize reliable clamping of rollers of different diameters. At the same time, the coaxial installation ensures that the rotation center of the roller is consistent with the center of the rotary disk, avoiding the problem of uneven grinding caused by eccentricity.

[0030] Specifically, the support frame 5 is installed on the rear side of the upper surface of the support platform 1, and the telescopic end of the telescopic component 7 is vertically fixed to the upper front side of the support frame 5 by bolts, and the telescopic end of the telescopic component 7 is fixedly connected to the upper surface of the support plate 6. Setting the support frame 5 on the rear side can avoid interference with the clamping and removal of the idler rollers, improve the convenience of operation, and the vertically set telescopic component 7 can ensure the straightness of the vertical movement of the support plate 6.

[0031] Specifically, the front side of the support frame 5 is bolted with two vertically arranged slide rails 9, and the lower part of the support plate 6 is equipped with a slider 10 that works with the slide rails 9. The telescopic component 7 can drive the support plate 6 and the slider 10 to move up and down along the slide rails 9. The cooperation structure between the slide rail and the slider can accurately guide the movement direction of the support plate 6, prevent the support plate from shifting or shaking during the up and down movement, ensure the relative position of the grinding component and the roller is stable, and improve the grinding accuracy. In this embodiment, the slider 10 is a linear slider of model HGW25CA, and the slide rail 9 is a linear slide rail of model HGR25.

[0032] Specifically, each grinding component includes a support cylinder 11, on which a vertically arranged rotating shaft 12 is rotatably connected. The bottom of the rotating shaft 12 passes through the lower surface of the support cylinder 11 and is detachably and fixedly connected to a grinding head 13. This detachable structure allows for easy replacement of the appropriate grinding head model for the inner or outer wall of the roller according to grinding requirements, improving the flexibility of the device. The tops of the two rotating shafts 12 pass through the upper surfaces of the support cylinder 11 and the support plate 6, and are respectively fixedly fitted with a first driven pulley 14 and a second driven pulley 15. The second drive assembly 8 is vertically fixedly installed by bolts. On the support plate 6, and at the output end of the second drive assembly 8, a first drive pulley 16 and a second drive pulley 17 are fixedly sleeved. The first drive pulley 16 and the first driven pulley 14 are connected by a first transmission belt 18, and the second drive pulley 17 and the second driven pulley 15 are connected by a second transmission belt 19. With the transmission structure of double drive pulleys and double driven pulleys, two sets of grinding assemblies can be driven to rotate in the same direction simultaneously by a single second drive assembly. This simplifies the device structure while ensuring that the speed of the two grinding heads is synchronized, thus improving the uniformity of grinding.

[0033] Specifically, a connecting plate 20 is fixedly installed on the upper surface of the support cylinder 11 by bolts. Three horizontally arranged adjustment elongated holes 21 are evenly opened on the support plate 6. The connecting plate 20 is provided with a fixing hole 22 that cooperates with the adjustment elongated holes 21. The top of the rotating shaft 12 extends out of the support plate 6 through the middle adjustment elongated hole 21, and the axis of the rotating disk 2 passes through the middle adjustment elongated hole 21. By adjusting the fixed position of the connecting plate 20 on the adjustment elongated hole 21, the grinding component can be moved in the horizontal direction to adapt to the grinding needs of rollers with different diameters. The corresponding design of the middle adjustment elongated hole 21 and the axis of the rotating disk 2 ensures that the adjustment center of the grinding component is consistent with the rotation center of the roller, thus improving the adjustment accuracy.

[0034] Specifically, the support plate 6 is also equipped with a first tensioning pulley 23 for tensioning the first transmission belt 18 and a second tensioning pulley 24 for tensioning the second transmission belt 19. Both the first tensioning pulley 23 and the second tensioning pulley 24 are rotatably connected to the rotating rod 25. The support plate 6 is symmetrically provided with two elongated holes 26 on the left and right. The two rotating rods 25 are detachably and fixedly connected to the two elongated holes 26, and the two elongated holes 26 are in a figure-eight shape. By adjusting the position of the rotating rod on the figure-eight elongated hole, the contact angle and pressure between the tensioning pulley and the transmission belt can be changed, thereby achieving precise adjustment of the transmission belt tension, effectively avoiding belt slippage, ensuring transmission efficiency and the stability of the grinding head speed. The figure-eight structure design makes the tension adjustment range wider and adapts to the transmission needs under different working conditions.

[0035] The specific work process for this application is as follows:

[0036] 1. Roller clamping: The operator places the roller to be ground vertically between the jaws of the three-jaw chuck, activates the clamping mechanism of the three-jaw chuck, and the jaws move radially and contact the inner wall of the roller to achieve centering and clamping of the roller, ensuring that the roller does not loosen during rotation.

[0037] 2. Grinding component adjustment: According to the diameter specification of the idler roller, loosen the fixing bolts on the connecting plate 20, move the support cylinder 11 along the adjustment elongated hole 21, so that the distance between the grinding head and the outer / inner wall of the idler roller is about 2mm. After the adjustment is completed, tighten the fixing bolts to fix the support cylinder 11. At the same time, adjust the position of the rotating rod 25 in the elongated hole 26 to make the synchronous belt tensioned and ensure stable transmission.

[0038] 3. Height adjustment: Start the hydraulic cylinder, the piston rod extends and drives the support plate 6 to move downward along the slide rail 9, so that the grinding head contacts the upper part of the idler roller. Set the initial height of the support plate 6 according to the length of the idler roller to ensure that the grinding head can cover the entire length range of the idler roller.

[0039] 4. Grinding and Rust Removal: Simultaneously start the first drive assembly 3 and the second drive assembly 8. The first drive assembly drives the rotating disk 2 and the idler roller to rotate at a constant speed, and the second drive assembly drives the grinding head to rotate at a constant speed. Start the hydraulic cylinder 7, and the piston rod slowly extends, driving the support plate 6 to move downward. The grinding head contacts the surface of the idler roller and performs grinding and rust removal until the support plate 6 moves to the lowest position, completing one grinding stroke. Then, the hydraulic cylinder 7 drives the support plate 6 to reset, the first drive assembly 3 and the second drive assembly 8 stop running, the three-jaw chuck is released, and the operator removes the ground idler roller and enters the next work cycle.

[0040] 5. Equipment maintenance: After each work session, clean the rust and impurities from the surface of the grinding head, check the tension and wear of the timing belt, adjust it through the tensioning wheel if it is loose, and replace it in time if it is severely worn; add lubricating oil to the slide rails, bearings and other moving parts regularly to ensure smooth operation of the equipment.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
