Description

Technical Field

[0001] This utility model relates to the field of cleaning brush technology, and more specifically, to a quick-change cleaning brush assembly. Background Technology

[0002] Cleaning brushes are common cleaning tools consisting of bristles and a handle. They are mainly used to remove dust, stains, and debris from the surface of objects. Industrial brushes refer to those used in industrial production processes for cleaning, dust removal, and polishing, such as brush rollers, drum brushes, wire brushes, strip brushes, sanitation vehicle sweeping brushes, and glass washing machine brush rollers.

[0003] However, most existing industrial brushes adopt a one-piece structure design. While this design ensures the overall strength of the brush to a certain extent, it brings significant drawbacks. With the high intensity and long-term operation of industrial production, the bristles are prone to problems such as curling and wear. Once such problems occur, since the brush cannot be disassembled, the user can only replace the entire brush.

[0004] Therefore, a quick-change cleaning brush assembly is proposed to address the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a quick-replaceable cleaning brush assembly, which can realize the function of easy and quick disassembly and replacement.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A quick-change cleaning brush assembly includes a base plate, a connecting component fixedly connected to the upper end of the base plate, a disassembly component slidably connected inside the connecting component, a brush structure slidably connected outside the disassembly component, and a driving component fixedly connected to the upper end of the base plate.

[0010] Furthermore, the connecting assembly includes a positioning plate, the lower end of which is fixedly connected to the upper end of the base plate, a bearing is fixedly connected to the inner surface of the positioning plate, and a slot is fixedly connected to the inner surface of the bearing.

[0011] Furthermore, the brush structure includes a brush tube, with two sliding strips fixedly connected to the inner surface of the brush tube, and a number of bristles fixedly connected to the outer surface of the brush tube. The bristles can be made of materials such as nylon, pig bristles, or steel wire, depending on different cleaning needs, and are arranged closely to effectively remove various stains.

[0012] Furthermore, the drive assembly includes a second positioning plate, the lower end of which is fixedly connected to the upper end of the base plate, a motor is fixedly connected to the rear end of the second positioning plate, the output end of the motor is fixedly connected to a second slot via a coupling, a second bearing is fixedly connected to the outer surface of the second slot, and the outer surface of the second bearing is fixedly connected to the inner surface of the second positioning plate.

[0013] Furthermore, the disassembly assembly includes a connecting rod with a groove at its front end. A spring is fixedly connected to the rear wall of the groove's inner cavity, and an insert rod is fixedly connected to the front end of the spring. The outer surface of the insert rod is slidably connected to the inner cavity of the groove. A limit ring is fixedly connected to the outer surface of the connecting rod, and two guide grooves are formed on the outer surface. A locking ring is threaded onto the outer surface of the connecting rod. The spring is a compression spring with good elasticity and reset capability. The limit ring is used to restrict the sliding position of the brush tube and prevent it from sliding excessively and detaching from the connecting rod. Rotating the locking ring can firmly fix the brush tube to the connecting rod.

[0030] In this design, the push rod base plate 1 positions the connecting component 2 and the driving component 5. The connecting component 2 and the driving component 5 cooperate with the disassembly component 3 to provide support and drive, while also enabling quick disassembly of the brush. The disassembly component 3 cooperates with the brush structure 4 to achieve quick brush replacement.

[0031] Please see Figure 2-5 The connecting component 2 includes a positioning plate 21, the lower end of which is fixedly connected to the upper end of the base plate 1, a bearing 22 is fixedly connected to the inner surface of the positioning plate 21, and a slot 23 is fixedly connected to the inner surface of the bearing 22.

[0032] The brush structure 4 includes a brush tube 41, the inner surface of the brush tube 41 is slidably connected to the outer surface of the connecting rod 31, two slide bars 42 are fixedly connected to the inner surface of the brush tube 41, the outer surfaces of the two slide bars 42 are slidably connected to the inner surfaces of the two guide grooves 36 respectively, and a number of bristles 43 are fixedly connected to the outer surface of the brush tube 41.

[0033] The bristles 43 can be made of a suitable material depending on the application scenario to meet cleaning needs.

[0034] The drive assembly 5 includes a second positioning plate 51. The lower end of the second positioning plate 51 is fixedly connected to the upper end of the base plate 1. A motor 52 is fixedly connected to the rear end of the second positioning plate 51. The output end of the motor 52 is fixedly connected to a second slot 53 through a coupling. A second bearing 54 is fixedly connected to the outer surface of the second slot 53. The outer surface of the second bearing 54 is fixedly connected to the inner surface of the second positioning plate 51.

[0035] The disassembly assembly 3 includes a connecting rod 31. The outer surface of the connecting rod 31 is slidably connected to the inner cavity of slot 2 53. A groove 32 is provided at the front end of the connecting rod 31. A spring 33 is fixedly connected to the rear wall of the inner cavity of the groove 32. An insertion rod 34 is fixedly connected to the front end of the spring 33. The outer surface of the insertion rod 34 is slidably connected to the inner cavity of slot 1 23. The outer surface of the insertion rod 34 is slidably connected to the inner cavity of the groove 32. A limit ring 35 is fixedly connected to the outer surface of the connecting rod 31. Two guide grooves 36 are provided on the outer surface of the connecting rod 31. A locking ring 37 is threadedly connected to the outer surface of the connecting rod 31.

[0036] During installation, first rotate the locking ring 37 to unscrew it from the connecting rod 31. Then, align the two sliding strips 42 inside the brush tube 41 with the two guide grooves 36 on the outer surface of the connecting rod 31. Slide the brush tube 41 along the guide grooves 36 until the brush tube 41 abuts against the limiting ring 35. Then, screw the locking ring 37 onto the outer surface of the connecting rod 31 and tighten it so that it abuts against one end of the brush tube 41. The brush tube 41 is then firmly fixed to the connecting rod 31 under the combined action of the limiting ring 35 and the locking ring 37.

[0037] Press the insert rod 34 to retract it into the slide groove 32. At this time, the spring 33 is in a compressed state. Then, insert the connecting rod 31 into the slot 2 53 and align the connecting rod 31 with the slot 1 23. Release the insert rod 34 to allow the spring 33 to return to its original position, so that the insert rod 34 can be inserted into the slot 1 23, thus completing the connection between the disassembly component 3, the connecting component 2, and the drive component 5.

[0038] Start the motor 52, and the slot 2 53 will rotate on the inner surface of the positioning plate 2 51 under the action of the motor 52 and the cooperation of the bearing 2 54. At this time, the connecting rod 31 will rotate under the action of the slot 2 53 and the cooperation of the bearing 1 22 and the slot 23. Since the brush structure 4 is fixed on the connecting rod 31, when the connecting rod 31 rotates, the brush structure 4 will rotate synchronously with the connecting rod 31. The bristles 43 can perform cleaning operations on the objects that need to be cleaned in the state of high-speed rotation.

[0039] When the bristles 43 are worn and need to be replaced, turn off the motor 52, then press the insertion rod 34 to retract it from the slot 23, and pull the disassembly component 3 out from the connecting component 2 and the drive component 5. After the disassembly component 3 is removed, rotate the locking ring 37 to remove it from the connecting rod 31 again, and then slide the brush tube 41 out along the guide groove 36. After replacing the new brush structure 4, reassemble it according to the above installation steps. It is quick and convenient.

[0040] It should be noted that the motor 52 in this utility model is powered by a power source and controlled by a controller.

[0041] It should be noted that the specific installation method, circuit connection method and control method of the motor 52 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0042] Working principle:

[0043] When it is necessary to install or replace the brush, first rotate the locking ring 37 to unscrew it from the connecting rod 31. Then, align the two sliding strips 42 inside the brush tube 41 with the two guide grooves 36 on the outer surface of the connecting rod 31. Slide the brush tube 41 along the guide grooves 36 until the brush tube 41 abuts against the limiting ring 35. Then, screw the locking ring 37 onto the outer surface of the connecting rod 31 and tighten it so that it abuts against one end of the brush tube 41. The brush tube 41 is then firmly fixed to the connecting rod 31 under the combined action of the limiting ring 35 and the locking ring 37. (When replacing the brush, after removing the locking ring 37, pull out the old brush structure 4 and put the new brush structure 4 on the connecting rod 31.)

[0044] Then press the insertion rod 34 to retract it into the slide groove 32. At this time, the spring 33 is in a compressed state. Then insert the connecting rod 31 into the slot 2 53 and align the connecting rod 31 with the slot 1 23. Release the insertion rod 34 to allow the spring 33 to return to its original position, so that the insertion rod 34 can be inserted into the slot 1 23, thus completing the connection between the disassembly component 3, the connecting component 2, and the drive component 5.

[0045] When in use, start the motor 52, and the slot 2 53 will rotate on the inner surface of the positioning plate 2 51 under the action of the motor 52 and the cooperation of the bearing 2 54. At this time, the connecting rod 31 will rotate under the action of the slot 2 53 and the cooperation of the bearing 1 22 and the slot 1 23. Since the brush structure 4 is fixed on the connecting rod 31, when the connecting rod 31 rotates, the brush structure 4 will rotate synchronously with the connecting rod 31. The bristles 43 can perform cleaning operations on the objects that need to be cleaned in the state of high-speed rotation.

[0046] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
