Description

Technical Field

[0001] The utility model relates to the technical field of disc brush cleaning machines, in particular to a disc brush device and a disc brush cleaning machine. Background Art

[0002] The disc brush cleaning machine is an indispensable process equipment in the glass substrate production industry. Its working principle is to use a disc brush that adjusts the rotation to perform contact brushing on the upper and lower surfaces of the glass substrate. In the equipment, two rows of disc brushes are placed opposite each other and can be rotated and adjusted as a whole. The glass substrate flows from the butt surface of the two layers of disc brushes, thereby achieving brushing on the upper and lower surfaces of the glass substrate. Due to the small brushing area of ​​the disc brush and the large size of the glass substrate, each row of disc brush devices needs to be installed with multiple disc brushes to achieve brushing of the entire glass substrate surface; at the same time, in order to meet the size adjustment of the upper and lower disc brushes and the amount of pressure on the glass substrate, how to better match the rotation drive and lifting adjustment of the disc brush has become a key technical issue.

[0003] Existing disc brush devices mostly use a drive shaft to simultaneously drive a row of bevel gears to rotate. Each bevel gear drives a disc brush to rotate to realize the rotation of the entire row of disc brushes. The drive shaft is directly connected to the motor. This structure has the following problems that need to be solved: 1. Due to process requirements, the entire row of disc brushes needs to be raised and lowered, so each row of disc brush devices requires a separate motor to perform the lifting and lowering action simultaneously with it, which is complex to control and has high costs; 2. There are many mechanisms extending outward along the drive shaft to the side of the cleaning machine, and the space is limited, which makes the cleaning machine difficult to maintain.

[0004] CN113020015A discloses a multi-disc brush plate cleaning device, which is different from the existing method of a motor drive shaft driving a row of bevel gears to drive the disc brushes to rotate, but the motor drives the transmission mechanism to drive each transmission assembly, so that the transmission gears at the same end rotate in the same direction, and then the adjacent transmission gears are driven to rotate through the disc brush gear rings meshing with them, and then all the disc brush gear rings on the transmission assembly are driven in sequence. This method has a relatively complex structure and high start-stop hysteresis. Utility Model Content

[0005] A technical problem to be solved by the utility model is that each row of disc brush devices in the existing disc brush cleaning machine needs to be driven by a separate motor, which is complex to control and has a high cost.

[0008] In some embodiments, the driven flat gear and the first driving bevel gear are both disposed on the first transition shaft and are integrally connected.

[0028] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0029] In order to solve the problem in the prior art that each row of disc brush devices in a disc brush cleaning machine requires a separate motor drive, which is complex to control and has high cost, the utility model provides a disc brush device in the first aspect, comprising: a driving mechanism, the driving mechanism comprising a motor drive shaft 9 extending along a first direction; a cleaning mechanism, the cleaning mechanism comprising two cleaning components 1 arranged opposite to each other along the first direction, the two cleaning components 1 comprising a disc brush shaft 13 extending along the first direction and a disc brush 14 arranged on the disc brush shaft 13; and a transmission mechanism, the transmission mechanism comprising two transmission components 15 axially spaced and transmission-connected to the motor drive shaft 9, the two transmission components 15 being transmission-connected to the two cleaning components 1 respectively.

[0030] Among them, Figure 1-2 As shown, the first direction can be set to a vertical direction, and the disc brush shaft 13 of the cleaning mechanism is parallel to the motor drive shaft 9 in the first direction. The disc brush shafts 13 on the two cleaning components 1 extend in opposite directions in the first direction so that the two cleaning components 1 are arranged opposite to each other. One end of the transmission component 15 is transmission-connected to the motor drive shaft 9, and the other end is transmission-connected to the disc brush shaft 13 of the cleaning component 1. The transmission mechanism can make the disc brush shaft 13 independent of the motor drive shaft 9, and can change the extension direction of the disc brush shaft 13 relative to the motor drive shaft 9, so that the two cleaning components 1 can be connected to the same motor drive shaft 9 respectively and one motor drive shaft 9 can control the two cleaning components 1 at the same time.

[0031] In this solution, two transmission components 15 are arranged at intervals on the motor drive shaft 9 of the driving mechanism, so that the same shaft can control the operation of the two cleaning components 1; the transmission mechanism is used to change the extension direction of the disc brush shaft 13 of the cleaning mechanism connected to the driving mechanism so that it is parallel to the motor drive shaft 9 of the driving mechanism, and the two cleaning components are further arranged oppositely to clean the two surfaces of the disc brush 14. Compared with the existing disc brush cleaning machine that uses two motor drive shafts to drive the upper and lower sets of disc brushes respectively, the disc brush device of the present application has a simple structure and low cost.

[0032] In some embodiments, each transmission assembly 15 includes a driving flat gear 8 disposed on a motor drive shaft 9, a driven flat gear 4 meshing with the driving flat gear 8, a first driving bevel gear 3 coaxial with the driven flat gear 4, and a first driven bevel gear 2 meshing with the first driving bevel gear 3. Figure 1 As shown, the driving flat gears 8 of the two transmission assemblies 15 can be respectively sleeved on both ends of the motor drive shaft 9. The driven flat gear 4 is coaxial with the first driving bevel gear 3, so that when the driving flat gear 3 rotates, the driven flat gear 4 and the first driving bevel gear 3 are driven to rotate synchronously. The first driving bevel gear 3 and the first driven bevel gear 2 cooperate, so that the extension direction of the transmission assembly 15 is rotated 90 degrees relative to the original first direction.

[0033] In some embodiments, the driven flat gear 4 and the first driving bevel gear 3 are both disposed on the first transition shaft 5 and are integrally connected. Figure 1 As shown, the driven flat gear 4 and the first active bevel gear 3 can be fixed by bolts to achieve an integral connection, so that the motor drive shaft 9 and the first transition shaft 5 can rotate synchronously, and the first driven bevel gear 2 meshing with the first active bevel gear 3 can drive the second transition shaft 10 to rotate synchronously, avoiding hysteresis in the overall transmission.

[0034] In some embodiments, each transmission assembly 15 further includes a second transition shaft 10 extending along a second direction, a second active bevel gear 11 disposed on the second transition shaft 10, and a second driven bevel gear 12 meshing with the second active bevel gear 11, wherein the second direction is perpendicular to the first direction. Figure 2 As shown, the first active bevel gear 3 cooperates with the first driven bevel gear 2, so that the extension direction of the transmission assembly 15 rotates relative to the original first direction to the second direction perpendicular to the first direction, that is, the extension direction of the second transition shaft 10. The second active bevel gear 11 on the second transition shaft 10 cooperates with the second driven bevel gear 12, so that the extension direction of the transmission assembly 15 continues to rotate 90 degrees to the first direction perpendicular to the second direction, that is, the extension direction of the disc brush shaft 13.

[0035] In some embodiments, the first driven bevel gear 2 is disposed on the second transition shaft 10, and the second driven bevel gear 12 is disposed on the disc brush shaft 13. Figure 2 As shown, the first driven bevel gear 2 can be arranged near one end of the second transition shaft 10, the second driving bevel gear 10 can be connected to the second transition shaft 10 by a key, and the second driven bevel gear 12 can be connected to the disc brush shaft 13 by bolts.

[0036] In some embodiments, a plurality of disc brush shafts 13 are disposed at intervals on each second transition shaft 10. Figure 2 As shown, the disc brush device requires multiple disc brushes 14 to fully clean the glass surface, so multiple disc brush shafts 13 can be spaced apart on the second transition shaft 10 to connect the multiple disc brushes 14, and the disc brush shafts 13 are preferably equally spaced in the second direction.

[0037] In some embodiments, the driving mechanism further includes a motor 6, and the motor 6 is connected to the motor drive shaft 9 via a coupling 7. Figure 1 As shown, the coupling 7 is arranged at the end of the motor drive shaft 9. In some other embodiments, the coupling 7 can also be replaced by a gear, a chain, etc. according to the actual volume of the disc brush device.

[0038] The second aspect of the utility model provides a disc brush cleaning machine, comprising: the disc brush device mentioned above; a lifting platform, the lifting platform is used to install a transmission mechanism and a cleaning mechanism; and a shell, the shell has a space for accommodating the disc brush device and the lifting platform.

[0039] The lifting platform can drive the connected transmission assembly 15 and the cleaning assembly 1 to move a certain distance in the first direction as a whole, and each connected transmission assembly 15 and the cleaning assembly 1 can be lifted and lowered as a whole. The lifting platform is a conventional lifting device, and its lifting and lowering can be achieved by a screw mechanism or a worm gear mechanism. When the lifting platform is lifted and lowered, the driven flat gear 4 on the transmission assembly 15 can move up and down in the first direction along the tooth surface of the driving flat gear 8, so the lifting platform does not affect the transmission of the disc brush device when adjusting the lifting height.

[0040] It should be noted that in the aforementioned disc brush device, since there is no relative motion between the active flat gear 8 and the driven flat gear 4, the transmission mechanism can be connected to the driving mechanism first through the flat gear set and then through the bevel gear set, or can be connected to the driving mechanism first through the bevel gear set and then through the flat gear set. However, in the disc brush cleaning machine, since the lifting platform needs to drive the transmission mechanism and the cleaning mechanism to realize the motion in the first direction, the transmission mechanism and the driving mechanism in the disc brush cleaning machine are set to be connected by flat gears.

[0041] In some embodiments, the drive mechanism includes a motor 6, a motor drive shaft 9 passes through the housing, and the motor 6 is disposed outside the housing. Figure 1 As shown, the motor drive shaft 9 passes through the housing in a first direction, and the motor 6 can be arranged on the top of the housing. In the existing cleaning machines, most of the mechanisms extend outward along the motor drive shaft to the side of the cleaning machine, so the installation space on the side is limited, which makes the cleaning machine difficult to maintain. However, the space on the top of the equipment is large, and placing the motor in this position is convenient for maintenance and repair.

[0042] In some embodiments, the adjustable distance range of the lifting platform in the first direction is set to 3 to 5 mm. Figure 1 As shown, the adjustable distance of the lifting platform in the first direction should be smaller than the thickness difference between the driving flat gear 8 and the driven flat gear 4. In some specific embodiments, the adjustable distance range of the lifting platform in the first direction can be set to 3 to 5 mm.

[0043] So far, various embodiments of the present invention have been described in detail. In order to avoid obscuring the concept of the present invention, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.

[0044] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
