Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to a dustproof roller conveyor device. Background Technology

[0002] With the continuous acceleration of my country's industrial development, the automation level and efficiency of material conveying equipment are becoming increasingly higher. Roller conveyors, which are mechanical devices that use the rotation of multiple parallel rollers to move objects, are widely used in logistics, manufacturing, warehousing, and other fields. Currently, roller conveyors are widely used in the ceramic production industry to transfer and transport products such as ceramic tiles. However, the transmission gear sets of existing roller conveyors are exposed to the working environment, where there is a large amount of ceramic dust. This dust easily accumulates between the transmission gear sets, leading to severe wear, short service life, and frequent maintenance and replacement, resulting in increased maintenance costs and reduced production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a dustproof roller conveyor device with compact structure, high transmission efficiency, long service life and low maintenance cost.

[0005] A dustproof roller conveying device includes a frame, on which multiple sets of conveying rollers and a drive motor for driving the conveying rollers to rotate are mounted. A profile trough is fixedly installed on one side of the frame, and a drive shaft is disposed within the profile trough. The drive shaft is equipped with a driving gear and multiple sets of transmission helical gears. A top cover plate is fixedly mounted on the profile trough, and multiple sets of sealed bearing seats are fixedly mounted on the top cover plate. A first bearing and a second bearing are disposed within the sealed bearing seats. A driven helical gear is disposed at one end of the conveying roller near the profile trough. The conveying roller passes through the sealed bearing seats, and the driven helical gear is located between the first bearing and the second bearing. The driving gear is poweredly connected to the drive motor, and the driven helical gear is meshed with the transmission helical gears.

[0006] As a further improvement to the above technical solution:

[0007] The top cover plate has a first connecting port, and the bottom of the sealed bearing seat has a second connecting port. The transmission helical gear located in the profile groove passes through the first connecting port and the second connecting port and meshes with the driven helical gear located in the sealed bearing seat.

[0008] The top of the sealed bearing housing is provided with an oil inlet, and the sealed bearing housing is provided with a dust plug for sealing the oil inlet.

[0009] The profile groove is provided with several sets of centering bearing seats, and the drive shaft passes through the centering bearing seats.

[0010] The top cover plate is also provided with a third connecting port for the drive gear to pass through and a fourth connecting port for the centering bearing seat to pass through. A sealing cover for covering the drive gear and the centering bearing seat is fixedly provided on the top cover plate.

[0011] The top of the profile groove is formed with a first connecting end face and a second connecting end face. The top cover plate abuts against the first connecting end face and the second connecting end face. Fastening screws pass through the sealing bearing seat, the top cover plate and the first connecting end face or the second connecting end face in sequence, so that the sealing bearing seat, the top cover plate and the profile groove are fixedly connected.

[0012] End caps are fixedly installed at both ends of the profile groove, and a sealing gasket is provided between the end caps and the profile groove.

[0026] like Figures 1 to 7As shown, the dustproof roller conveying device of this embodiment includes a frame 1, on which multiple sets of conveying rollers 2 and a drive motor 3 for driving the conveying rollers 2 to rotate are arranged. A profile trough 4 is fixedly installed on one side of the frame 1. A transmission shaft 5 is arranged inside the profile trough 4. The transmission shaft 5 is provided with a drive gear 501 and multiple sets of transmission helical gears 502. A top cover plate 6 is fixedly arranged on the profile trough 4. Multiple sets of sealed bearing seats 7 are fixedly arranged on the top cover plate 6. A first bearing 701 and a second bearing 702 are arranged inside the sealed bearing seats 7. A driven helical gear 201 is provided at one end of the conveying roller 2 near the profile trough 4. The conveying roller 2 passes through the sealed bearing seat 7, and the driven helical gear 201 is located between the first bearing 701 and the second bearing 702. The drive gear 501 is poweredly connected to the drive motor 3, and the driven helical gear 201 is meshed with the transmission helical gear 502. The dustproof roller conveyor includes a conveying roller 2 and a drive motor 3. The drive motor 3 and the conveying roller 2 are connected by a transmission shaft 5. A profile trough 4 is mounted on the frame 1, and the transmission shaft 5 is located inside the profile trough 4. A top cover plate 6 is provided on the profile trough 4, so that the entire transmission shaft 5 is located within the sealed space of the profile trough 4. At the same time, a sealed bearing seat 7 is provided on the top cover plate 6, and the conveying roller 2 passes through the sealed bearing seat 7, so that the driven helical gear 201 and the transmission helical gear 502 are within the sealed space of the sealed bearing seat 7. The device achieves meshing connection, provides excellent dust prevention, and prevents dust accumulation between the driven helical gear 201 and the transmission helical gear 502, as well as on the transmission shaft 5. This effectively reduces gear wear and extends service life. Furthermore, the sealed bearing housing 7 has a first bearing 701 and a second bearing 702 on both sides of the driven helical gear 201, which effectively reduces the frictional resistance of the conveying roller 2 and improves its load-bearing capacity. The dustproof roller conveying device of this utility model has the advantages of compact structure, high transmission efficiency, long service life, low maintenance cost, and high production efficiency.

[0027] It should be noted that the axis of the drive shaft 5 is perpendicular to the axis of the conveying roller 2. In this embodiment, the power transmission is achieved by the meshing connection between the drive helical gear 502 and the driven helical gear 201, which has the advantages of high transmission efficiency, strong load-bearing capacity and high precision. In other embodiments, the transmission connection between the drive shaft 5 and the conveying roller 2 can also be achieved by bevel gear sets, worm gears and other components, and is not limited to this embodiment.

[0028] Preferably, the top cover plate 6 has a first connecting port 601, and the bottom of the sealed bearing seat 7 has a second connecting port 703.

In other embodiments, when the diameters of the drive gear 501 and the centering bearing seat 9 are both smaller than the diameter of the transmission helical gear 502, that is, when the drive gear 501 and the centering bearing seat 9 are both located inside the profile groove 4, the top cover plate 6 does not need to have a third connecting port 602 and a fourth connecting port 603, and is not limited to this embodiment.

[0032] Preferably, the top of the profile groove 4 is formed with a first connecting end face 401 and a second connecting end face 402. The top cover plate 6 abuts against the first connecting end face 401 and the second connecting end face 402. The fastening screws pass through the sealing bearing seat 7 and the top cover plate 6 in sequence and are set with the first connecting end face 401 or the second connecting end face 402, so that the sealing bearing seat 7, the top cover plate 6 and the profile groove 4 are fixedly connected, which has high assembly efficiency and can effectively improve the connection stability between the top cover plate 6 and the profile groove 4.
