Description

Technical Field

[0001] This utility model relates to the technical field of oil-free anti-wear support rollers for heavy-duty plate feeders, specifically an oil-free anti-wear support roller for heavy-duty plate feeders. Background Technology

[0002] Heavy-duty plate feeders are generally used for mineral conveying, also known as iron plate feeders. Their advantages include the ability to perform heavy-duty work in harsh environments, providing uniform, accurate, stable, and reliable feeding. They are also highly adaptable to changes in material particle size and composition, temperature, viscosity, frost, rain, snow, or frozen materials. The support rollers of a heavy-duty plate feeder are devices used to improve the stability of mechanical equipment and reduce vibration. Support rollers typically consist of one or more weights that rotate to generate centrifugal force, thus balancing the equipment.

[0003] However, traditional support rollers require regular lubrication. Since multiple support rollers are typically used together, and each roller bears different loads, the lubricant consumption varies. Regular lubrication may cause some rollers to prematurely deplete their lubricant, increasing the friction coefficient between the roller body and the roller shaft, thus accelerating the roller's lifespan. Furthermore, regular lubrication increases labor and material costs, raising maintenance expenses. Therefore, a lubrication-free, wear-resistant support roller for heavy-duty plate feeders is proposed to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to provide an oil-free, wear-resistant support roller for a heavy-duty plate feeder, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant, oil-free support roller for a heavy-duty plate feeder, comprising a support roller body, the support roller body including a support roller shaft, circular pins inserted into the inner walls of both sides of the support roller shaft, a cover plate sleeved on the outer wall of the circular pins, a bearing sleeve sleeved on the outer wall of the cover plate, oil seal sleeves sleeved on both sides of the support roller shaft, a reinforcing bushing sleeve sleeved on the outer wall at the connection between the oil seal sleeve and the bearing sleeve, an annular oil-passing gasket ring sleeved on the outer wall of the middle section of the support roller shaft, and a threaded plug sleeve threadedly connected to the inner wall of the reinforcing bushing.

[0006] Preferably, a connecting bushing is fitted onto the outer wall of the middle section of the support roller axle, and a sealing plug is fitted onto the inner wall of the limiting opening of the connecting bushing.

[0007] Preferably, the inner wall of the reinforcing bushing has a through hole; high-quality industrial gear oil can disperse heat and play a certain cooling role; the threaded plug sleeve can limit the installation of the connected support roller shaft and fix it to the external equipment, thereby playing a fixed support role for the support roller and facilitating its use.

[0008] Preferably, the through hole is connected to the limiting groove opened in the threaded plug sleeve and the reinforcing bushing.

[0009] Preferably, the inner wall of the oil seal sleeve is provided with an oil storage cavity, which is connected to the through hole; when the connected support roller body rotates, the industrial gear oil inside enters the gap between the cover plate, the oil seal sleeve and the support roller shaft through the through hole, thereby playing a lubricating role when the support roller body rotates, reducing the friction coefficient between the oil seal sleeve and the support roller shaft.

[0010] Preferably, the inner wall of the connecting bushing is provided with an oil inlet channel, which is connected to the limiting hole provided in the sealing plug; the limiting hole of the connecting bushing is sealed by the sealing plug, and the gear oil flowing into the inner cavity of the connecting bushing flows into the oil storage chamber provided in the inner cavity of the oil seal sleeve through the oil inlet channel provided in the inner cavity of the connecting bushing. The track roller does not need to be lubricated or maintained during use, eliminating the manpower and material resources required for the regular addition of grease to the wheel body of traditional track rollers, thus saving maintenance costs.

[0011] Preferably, the annular oil-passing gasket ring has uniformly spaced limiting channels, and the limiting channels are connected to the oil inlet channel; an annular oil-passing gasket ring is sleeved on the outer wall of the connected support roller shaft, and the connected annular oil-passing gasket ring has uniformly spaced limiting channels, so that the falling gear oil can flow evenly into all parts of the outer wall of the support roller shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This heavy-duty plate feeder uses an oil-free, wear-resistant support roller. Oil is injected through a limiting hole in the middle of the connecting bushing, using high-quality industrial gear oil in a single application. The limiting hole of the connecting bushing is sealed by a sealing plug. Gear oil flowing into the inner cavity of the connecting bushing passes through an oil inlet channel and into an oil storage chamber within the oil seal sleeve. The support roller requires no oiling or maintenance during use, eliminating the need for the manpower and resources required to periodically add grease to the roller body, as is common with traditional support rollers, thus saving maintenance costs.

[0014] 2. This heavy-duty plate feeder uses an oil-free, wear-resistant support roller. An annular oil-passing gasket is fitted onto the outer wall of the connected support roller shaft. The annular oil-passing gasket has evenly spaced limiting holes, allowing gear oil to flow evenly into all parts of the outer wall of the support roller shaft. When the support roller rotates, the industrial gear oil inside enters through the through holes into the gap between the cover plate, oil seal sleeve, and the support roller shaft, thus providing lubrication and reducing the friction coefficient between the oil seal sleeve and the support roller shaft. Simultaneously, the high-quality industrial gear oil can dissipate heat, providing a certain cooling effect. Threaded plug sleeves and threaded plug sleeves can limit the installation of the connected support roller shaft and fix it to external equipment, thus providing a fixed support for the support roller and facilitating its use.

[0021] Please see Figures 1-4This utility model provides a technical solution: a wear-resistant, oil-free support roller for a heavy-duty plate feeder, comprising a support roller body 1, the support roller body 1 including a support roller shaft 102, circular pins 104 inserted into the inner walls of both sides of the support roller shaft 102, a cover plate 108 sleeved on the outer wall of the circular pins 104, a bearing sleeve 103 sleeved on the outer wall of the cover plate 108, oil seal sleeves 107 sleeved on both sides of the outer walls of the support roller shaft 102, a reinforcing bushing 105 sleeved on the outer wall of the connection between the oil seal sleeve 107 and the bearing sleeve 103, an annular oil-passing gasket ring 112 sleeved on the outer wall of the middle section of the support roller shaft 102, and a threaded plug sleeve 106 threadedly connected to the inner wall of the reinforcing bushing 105; the support roller A connecting sleeve 101 is fitted onto the outer wall of the middle section of shaft 102, and a sealing plug 111 is fitted onto the inner wall of the limiting port of the connecting sleeve 101; a through hole 109 is provided on the inner wall of the reinforcing sleeve 105; the through hole 109 is connected to the threaded plug sleeve 106 and connected to the limiting groove of the reinforcing sleeve 105; an oil seal sleeve 107 has an oil storage chamber 110 on its inner wall, and the oil storage chamber 110 is connected to the through hole 109; an oil inlet channel 113 is provided on the inner wall of the connecting sleeve 101, and the oil inlet channel 113 is connected to the limiting hole of the sealing plug 111; an annular oil gasket ring 112 has evenly spaced limiting channels, and the limiting channels are connected to the oil inlet channel 113.

[0022] Working principle: Oil is injected through the limiting hole in the middle section of the connecting bushing 101. High-quality industrial gear oil is added at once. The limiting hole of the connecting bushing 101 is sealed by the sealing plug 111. The gear oil flowing into the inner cavity of the connecting bushing 101 flows into the oil storage chamber 110 in the inner cavity of the oil seal sleeve 107 through the oil inlet channel 113 in the inner cavity of the connecting bushing 101. The support roller does not require oiling or maintenance during use, eliminating the manpower and material resources required for the regular addition of grease to the wheel body of traditional support rollers, saving maintenance costs. An annular oil passage gasket 112 is fitted on the outer wall of the connecting support roller shaft 102. The annular oil passage gasket 112 has evenly spaced limiting channels to facilitate the insertion of gears. Oil flows evenly into all parts of the outer wall of the support roller shaft 102. When the connected support roller body 1 rotates, the industrial gear oil inside 114 enters through the through hole 109 into the gap between the cover plate 108, the oil seal sleeve 107 and the support roller shaft 102. This lubricates the support roller body 1 during rotation, reducing the coefficient of friction between the oil seal sleeve 107 and the support roller shaft 102. At the same time, high-quality industrial gear oil can disperse heat and provide a certain cooling effect. The threaded plug sleeve 106 can limit the installation of the connected support roller shaft 102 and fix it to external equipment, thus providing a fixed support for the support roller and facilitating its use.
