Description

Technical Field

[0001] This utility model relates to the field of glass processing equipment technology, and in particular to a three-line cold end power cleaner. Background Technology

[0002] Glass products are widely used in various industries such as construction, automobiles, photovoltaics, and home appliances. Their production process typically includes multiple stages such as melting and forming, annealing and cooling, conveying and cleaning, and inspection and sorting. In the cold end area of ​​the glass, the glass sheets move through a roller conveyor system. During this process, dust particles easily adhere to the bottom surface. If not cleaned in time, it can easily affect the stability of subsequent processes such as coating, lamination, or optical inspection and the quality of the finished product. Therefore, setting up a powered cleaning device at the cold end to effectively clean the bottom surface of the glass has become an important measure to ensure the stable operation of the production line.

[0003] In existing technologies, powered cleaning devices typically achieve contact cleaning of the bottom surface of the glass by using a rotating brush roller positioned below the glass plate. The cleaning mechanism is mostly driven by a motor reducer to rotate the brush roller in the opposite direction, and the speed is adjusted by a frequency converter control system to adapt to the glass conveying speed. Although such devices can basically achieve automated cleaning, dust, debris or other impurities will accumulate on the brush itself during long-term operation. If it is not manually disassembled and cleaned periodically, its cleaning ability will gradually decrease, and it may even cause secondary pollution or damage to the glass surface, affecting the continuous operation of the equipment and product quality.

[0004] Therefore, a cold-end cleaning device with a more reasonable structure and self-cleaning brush roller is needed, so that the brush can clean itself while performing the function of cleaning glass, thereby improving the cleaning efficiency and continuous operation stability of the equipment, reducing maintenance workload, and meeting the needs of automated operation of modern glass production lines. Utility Model Content

[0005] This utility model aims to provide a three-line cold-end powered cleaner to solve the problems mentioned in the background art. This solution forms a multi-segment cleaning structure by setting multiple equidistantly arranged brush rollers below the glass moving path along the conveying direction. While achieving efficient cleaning of the bottom surface of the glass, it introduces an adjustment mechanism to drive the brush rollers to move closer together, so that the brush rollers contact each other and generate friction when not in operation, thereby achieving the self-cleaning function of the brush roller surface. This structure not only improves the cleaning device's efficiency in removing dust particles, but also significantly reduces the problem of frequent manual disassembly and cleaning of the brushes due to dust accumulation, enhances the continuous operation capability and stability of the equipment, improves the overall automation level, and plays a positive role in improving the operational reliability of existing cleaning equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The three-wire cold-end power sweeper includes a mounting base, a first bracket, and a pair of second brackets. A support base is provided on the upper side of the mounting base, and multiple electric push rods are connected to the mounting base. The output ends of the multiple electric push rods are all connected to the support base. The first bracket is connected to the top of the support base. The pair of second brackets are symmetrically distributed on both sides of the first bracket and are slidably connected to the support base. Brush rollers are rotatably connected to the inner ends of both the first and second brackets, and a first servo motor is connected to both the first and second brackets. The output end of the first servo motor is connected to the rotation shaft of the brush roller. An adjustment component for controlling the movement of the pair of second brackets is provided on the support base.

[0008] Preferably, the tips of the plurality of brush rollers are all at the same horizontal position.

[0009] Preferably, the adjustment assembly includes a second servo motor and a bidirectional lead screw. The second servo motor is connected to the support base, and the bidirectional lead screw is rotatably connected to the inner end of the support base. The bidirectional lead screw is also connected to the output end of the second servo motor. Each pair of second brackets has a lead screw sleeve that works in conjunction with the bidirectional lead screw at its bottom end.

[0010] Preferably, the outer end of the mounting base is detachably connected to a dust collection hood, which surrounds the outside of multiple brush rollers, and the top of the dust collection hood is slightly lower than the top of the brush rollers.

[0011] Preferably, the dust collection hood has openings at both the top and bottom, and the dust collection hood is configured with a structure that is larger at the top and smaller at the bottom.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0013] This solution uses multiple equidistantly arranged brush rollers along the conveying direction below the glass movement path to form a multi-segment cleaning structure. While achieving efficient cleaning of the bottom surface of the glass, it introduces an adjustment mechanism to drive the brush rollers to move closer together, allowing them to contact and rub against each other when not in operation, thus achieving a self-cleaning function. This structure not only improves the cleaning device's efficiency in removing dust particles but also significantly reduces the problem of frequent manual disassembly and cleaning of the brushes due to dust accumulation. It enhances the continuous operation capability and stability of the equipment, improves the overall automation level, and plays a positive role in improving the operational reliability of existing cleaning equipment.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0019] like Figure 1-3 The three-wire cold-end power cleaner shown includes a mounting base 1, a first bracket 4, and a pair of second brackets 5. A support base 3 is provided on the upper side of the mounting base 1, and multiple electric push rods 2 are connected to the mounting base 1. The output ends of the multiple electric push rods 2 are all connected to the support base 3. The first bracket 4 is connected to the top of the support base 3. The pair of second brackets 5 are symmetrically distributed on both sides of the first bracket 4 and are slidably connected to the support base 3. Brush rollers 6 are rotatably connected to the inner ends of the first bracket 4 and the second bracket 5. A first servo motor 7 is connected to the first bracket 4 and the second bracket 5. The output end of the first servo motor 7 is connected to the rotation shaft of the brush roller 6. An adjustment component for controlling the movement of the pair of second brackets 5 is provided on the support base 3. The tops of the multiple brush rollers 6 are all at the same horizontal position.

[0020] Glass products are widely used in construction, automobiles, photovoltaics, and home appliances. During the cold end conveying process, the bottom surface of the glass often becomes dusty, affecting the quality of subsequent processes. To ensure cleaning effectiveness, a rotating brush roller driven by a motor is usually installed under the glass plate for cleaning. However, the existing brushes are prone to dust accumulation and clogging after long-term operation, requiring manual cleaning, which affects cleaning efficiency and equipment stability. Therefore, there is an urgent need for a cold end cleaning device with self-cleaning function to improve cleaning performance, reduce maintenance frequency, and meet the automation requirements of modern production lines.

[0021] In this solution, the mounting base 1 is connected and fixed to the cold-end roller conveyor frame used for transporting glass, and is located on the lower side of the glass. Multiple electric push rods 2 are set on the mounting base 1 to drive the support base 3 to lift and lower as a whole, thereby driving the brush rollers 6 to achieve overall height adjustment. This allows multiple brush rollers 6 to abut against the bottom of the glass to adapt to the cleaning requirements of glass with different thicknesses or working conditions. The multiple brush rollers 6 are distributed sequentially in the glass conveying direction, so that the bottom surface of the glass passes through multiple brush areas in sequence during the conveying process, completing the cleaning process segment by segment. Each brush roller 6 is driven to rotate independently by a corresponding first servo motor 7, and the rotation direction is opposite to the glass conveying direction, thereby enhancing the cleaning friction and improving the cleaning effect. The multiple brush rollers 6 are arranged at equal intervals, which is conducive to achieving multi-level dust removal. While cleaning the bottom surface of the glass, the user can periodically control the movement of a pair of second brackets 5 through the adjustment component, forcing the multiple brush rollers 6 to stagger, generate mutual contact and friction, and achieve self-cleaning function, thereby effectively preventing problems such as dust accumulation and jamming of the brush rollers and maintaining cleaning efficiency.

[0022] The adjustment assembly includes a second servo motor 8 and a bidirectional lead screw 9. The second servo motor 8 is connected to the support base 3, and the bidirectional lead screw 9 is rotatably connected to the inner end of the support base 3. The bidirectional lead screw 9 is also connected to the output end of the second servo motor 8. A lead screw sleeve 10 that works with the bidirectional lead screw 9 is connected to the bottom end of each pair of second brackets 5.

[0023] In this solution, by controlling the forward and reverse rotation of the second servo motor 8, the bidirectional lead screw 9 can synchronously drive the two second supports 5 to move inward or outward, thereby controlling the brush rollers 6 connected to them to move closer to or separate from the brush rollers 6 located on the first support 4. During working intervals or no-load sections, multiple brush rollers 6 come into contact with each other and generate rotational friction, realizing the automatic peeling and desorption of dust and debris from the brush roller surface, achieving the purpose of self-cleaning. This structure avoids manual cleaning or frequent disassembly, improves the continuity and intelligence level of equipment operation, and is a key component in achieving "no manual maintenance".

[0024] A dust collection cover 11 is detachably connected to the outer end of the mounting base 1. The dust collection cover 11 surrounds the outside of multiple brush rollers 6, and the top of the dust collection cover 11 is slightly lower than the top of the brush rollers 6. Both the upper and lower ends of the dust collection cover 11 are open, and the dust collection cover 11 is designed with a structure that is larger at the top and smaller at the bottom.

[0025] In this design, a dust collection hood 11 is detachably connected to the outer end of the mounting base 1. The dust collection hood 11 surrounds the outside of multiple brush rollers 6, forming a partially enclosed space. Its top is slightly lower than the top of the brush rollers 6, which facilitates the partial exposure of the brush rollers 6 for cleaning. At the same time, it confines the dust generated during cleaning or self-cleaning within the hood to prevent the spread of pollution. The dust collection hood 11 has an open structure at both the top and bottom, which facilitates the dust falling into the dust collection device or exhaust duct. The hood adopts a structure design that is larger at the top and smaller at the bottom, which is conducive to the smooth settling and centralized collection of dust under the action of gravity, further improving the environmental protection performance and the cleanliness of the work site. In addition, it works with the self-cleaning function to ensure the cleanliness stability of the equipment during long-term operation.
