Description

Technical Field

[0001] This invention relates to the field of glass cleaning machine technology, and more particularly to a glass cleaning machine. Background Technology

[0002] Glass cleaning machines are common post-processing equipment in glass sheet processing. They use a combination of spraying and airflow to clean the dust and dust generated after edge grinding on the glass sheets during the glass sheet conveying process, and then blow the glass sheets dry.

[0003] Existing glass washing machines typically use fans to deliver airflow to air knives. However, traditional fans are too large and take up space when placed next to the washing machine. A glass washing machine with air knife drying, patent number CN202411398443.0, mounts the fan on top of the washing machine. However, since the fan needs to be inspected frequently, employees have to climb up and down often, which is not only troublesome but also easy to cause injury to employees. In addition, traditional fans need to be used in conjunction with heating equipment to generate hot air to dry the glass, which consumes a lot of energy. When cleaning glass, the glass plates need to be sprayed for cleaning. Traditional glass cleaning machines usually have a water tank on one side, with a filter screen at the top of the tank. A water pump is installed inside the tank to pump water to the glass cleaning machine. After cleaning the glass plates, the water is filtered through the filter screen and returned to the water tank. In this process, the filter screen can only filter impurities, but the water is still turbid. Using this water to clean subsequent glass plates will not produce good cleaning results. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a glass cleaning machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A glass cleaning machine includes a frame with a conveying assembly on the frame, a cleaning area and a drying area inside the frame, a cleaning device in the cleaning area, a drying device in the drying area, a fan unit on one side of the frame that supplies air to the drying device, and a water return device on the other side of the frame that supplies water to the cleaning device.

[0006] Preferably, the frame includes a housing, a support frame is connected to the lower side of the housing, the transmission mechanism is provided on the housing, and a cover is provided on the upper side of the housing, the cover being able to move up and down relative to the housing.

[0007] Preferably, a lifting mechanism is provided on the outside of the frame, and the lifting mechanism drives the cover to move up and down.

[0008] Preferably, the cleaning device includes a set of partition components that divide the cleaning area into a set of cleaning tanks, with a first spraying component and a cleaning roller assembly connected in each cleaning tank.

[0009] Preferably, a preliminary cleaning mechanism is also provided on one side inside the housing. The glass preliminary cleaning mechanism includes a cleaning tank, with inlets and outlets on both sides of the cleaning tank, and a second spray cleaning component and a first air knife are provided inside the cleaning tank.

[0010] Preferably, a first water outlet is provided at the bottom of each of the cleaning tanks, and a first drainage component is connected to the lower side of each first water outlet. The first drainage component is configured in conjunction with the water return device.

[0011] Preferably, a second water outlet is provided at the bottom of the cleaning tank, and a second drainage component is connected to the lower side of the second water outlet. The second drainage component is configured in conjunction with the water return device.

[0012] Preferably, the first spraying component and the second spraying component have the same structure. They both include a fixed rod and a vertical tube, and two horizontal tubes are fixedly connected between the fixed rod and the vertical tube. The two horizontal tubes are connected to the vertical tube, and a row of nozzles is connected to the upper and lower opposite sides of the two horizontal tubes.

[0013] Preferably, the water return device includes a water tank with an open upper side, at least one baffle connected inside the water tank, the baffle dividing the water tank into at least two water storage tanks, and a water pump connected to each water storage tank, the water pump being connected to the corresponding vertical pipe through a connecting pipe fitting.

[0014] Preferably, the air-drying device includes an air knife assembly, which includes an upper air knife and a lower air knife. The upper air knife is connected inside the housing, and the lower air knife is connected inside the housing.

[0015] The advantages of this invention are as follows: The glass washing machine provided by this invention uses an H-10 model fan, which is smaller in size. The fan unit is placed next to the frame, which occupies little space and does not hinder the movement of employees. In addition, it is more convenient to maintain the fan, and employees do not have to climb up and down, which ensures the safety of employees. Furthermore, the fan has a high rotation speed and generates air with its own heat, which can save energy. In addition, a water return device is used to supply water to the cleaning device. The dirty water after cleaning the glass is filtered through a filter screen and filter. The filtered water is cleaner. Using the filtered water to clean heavy glass not only has high cleaning efficiency, but also saves water resources. Finally, a set of spray washing components is used to clean the glass multiple times, and a set of cleaning rollers is also provided to rinse the glass, which can clean the glass thoroughly. After cleaning, the glass enters the drying area, where the drying device can quickly dry the glass. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0019] like Figure 1 and Figure 2 As shown, the present invention provides a glass cleaning machine, including a frame 1, the frame 1 including a housing 1.1. The housing 1.1 is a rectangular box structure with an open top. A cover 1.2 is attached to the upper side of the housing 1.1. A lifting mechanism 8 is provided on the outside of the frame 1. The lifting mechanism 8 drives the cover 1.2 to move up and down.

[0020] like Figure 12 As shown, the lifting mechanism 8 includes a set of screw jacks 8.1. The screw jacks 8.1 are existing structures. The lifting end of each screw jack 8.1 is rotatably connected to a support block 8.2. The support block 8.2 is connected to the cover 1.2 through a fixing plate 8.3. In this embodiment, there are six screw jacks 8.1, three on each side of the frame 1. In addition, the linkage of multiple screw jacks 8.1 for lifting is also existing technology. The output shafts of a set of screw jacks 8.1 are connected in series through a set of connecting shafts 8.4. Then, one of the connecting shafts 8.4 is driven to rotate by a first motor 8.5. The first motor 8.5 is connected to the frame 1. The first motor 8.5 synchronously drives a set of screw jacks 8.1 to lift, thereby driving the cover 1.2 to move up and down.

[0021] like Figure 4 As shown, a waterproof sleeve 8.6 is fitted onto the outside of the lead screw of each screw jack 8.1. The waterproof sleeve 8.6 is fixed to the upper side of the screw jack 8.1. When the lead screw of the screw jack 8.1 moves to the lowest position, the upper end of the lead screw is just flush with the upper end of the waterproof sleeve 8.6. That is, the height of the waterproof sleeve 8.6 will not affect the up and down movement of the cover 1.2. The waterproof sleeve 8.6 can prevent water from entering the interior of the screw jack 8.1.

[0022] A conveyor assembly 2 is provided on rack 1, such as Figure 3As shown, the conveying assembly 2 has an existing structure, including a conveying motor 2.1, a conveying shaft 2.2, and conveying rollers 2.3. The conveying motor 2.1 is connected to the frame 1, and the conveying shaft 2.2 is rotatably connected to one side of the frame 1. It can be connected to the shaft of the conveying motor 2.1 by means of a chain, belt, etc. The conveying rollers 2.3 are evenly distributed on the frame 1, and the conveying rollers 2.3 rotate synchronously when they rotate through a helical gear combination structure, so as to realize the continuous conveying of glass sheets. For details, please refer to the description of the conveying assembly in application number CN202411398443.0, which will not be elaborated here.

[0023] Additionally, a protective plate 2.4 is connected to the outside of the helical gear assembly structure. The protective plate 2.4 is an L-shaped plate, which protects the helical gear assembly structure. Protective covers 1.4 are connected to both sides of the frame 1, and the protective plate 2.4 is inside the protective cover 1.4.

[0024] The frame 1 is equipped with a cleaning area and a drying area. The cleaning area is equipped with a cleaning device 3, and the drying area is equipped with a drying device 4.

[0025] The cleaning device 3 includes a set of dividing components 3.1. In this embodiment, there are two dividing components 3.1. The two dividing components 3.1 divide the cleaning area into three cleaning tanks. The dividing components 3.1 include upper and lower dividing plates with a gap between them. A glass plate passes through the gap. The upper dividing plate is connected to the inside of the cover 1.3, and the lower dividing plate is connected to the inside of the housing 1.1. The upper and lower dividing plates can prevent the water from mixing between the various cleaning tanks. Each cleaning tank is provided with a first spray washing component 3.2 and a cleaning roller assembly 3.9.

[0026] The first spray cleaning component 3.2 and the second spray cleaning component 3.4 described below have the same structure, as follows: Figure 3 and Figure 5 Each of them includes a fixed rod 3.5 and a vertical tube 3.6. Two horizontal tubes 3.7 are fixedly connected between the fixed rod 3.5 and the vertical tube 3.6. The two horizontal tubes 3.7 are connected to the vertical tube 3.6. A row of nozzles 3.8 is connected to the upper and lower opposite sides of the two horizontal tubes 3.7. The upper and lower sides of the glass plate are sprayed and washed through the two rows of nozzles 3.8.

[0027] In this embodiment, the number of cleaning roller assemblies 3.9 is three, such as Figure 6 and Figure 8As shown, the cleaning roller assembly 3.9 includes an upper cleaning roller and a lower cleaning roller. The lower cleaning roller is disposed within the housing 1.1, and the upper cleaning roller is disposed within the cover 1.2. A rotating shaft 3.26 is connected to both ends of each cleaning roller. The rotating shaft 3.26 is inserted into a bearing seat, which slides up and down within a rectangular frame 3.27. The rectangular frame 3.27 is connected to either the housing 1.1 or the cover 1.2. A through hole is provided on the upper side of the rectangular frame 3.27, and a fixing rod 3.28 is inserted into the through hole. The fixing rod 3.28 is connected to the bearing seat, and the fixing rod 3.28 drives the bearing seat and the rotating shaft to move up and down, thereby... The cleaning rollers move up and down, adjusting the distance between the upper and lower cleaning rollers so that they can contact the upper and lower sides of the glass plate. An external thread is provided on the upper side of the fixing rod 3.28, which is fixed in place by two nuts threaded onto the external thread. A second motor 3.29 is connected to the outside of both the housing 1.1 and the cover 1.2. Both second motors 3.29 drive the upper and lower rotating shafts 3.26 synchronously via a belt and pulley structure, thereby driving the upper and lower cleaning rollers to clean the glass plate.

[0028] A preliminary cleaning mechanism is also provided on the side of the housing 1.1 near the inlet, such as... Figure 9 As shown, the glass preliminary cleaning mechanism includes a cleaning box 3.3, which is connected inside the housing 1.1. The cleaning box 3.3 has an inlet and an outlet on both sides. Inside the cleaning box 3.3, there is a second spray cleaning component 3.4 and a first air knife 3.9. The air outlet of the first air knife 3.9 is set downwards, and the airflow blows towards the upper side of the glass plate.

[0029] A baffle plate 10 is connected inside the housing 1.1. The baffle plate 10 is located between the cleaning device 3 and the drying device 4 to prevent water from entering the area of ​​the drying device 4.

[0030] The air drying device 4 includes an air knife assembly, which comprises an upper air knife 4.1 and a lower air knife 4.2. The upper air knife 4.1 is connected inside the housing 1.2, and the lower air knife 4.2 is connected inside the housing 1.1. Figure 7 As shown, both ends of all the air knives are fixedly connected to the frame 1 by clamps. The clamps include two semicircular parts 4.3 connected by bolts. One semicircular part is connected to the frame 1. The two semicircular parts 4.3 are fitted onto the outside of the air knife and then connected and fixed by bolts, thereby fixing the air knife to the frame 1. The clamps make it easy to disassemble the air knife.

[0031] Furthermore, the upper air knife 4.1 is installed above the conveying assembly 2, causing the airflow to exit above the glass plate, and the lower air knife 4.2 is installed below the conveying assembly 2, causing the airflow to exit below the glass plate. In this embodiment, the specific structures of the upper and lower air knives can be found in the descriptions of air knives in Chinese patent documents CN219817315U or CN221403830U, and will not be detailed here.

[0032] Traditional fans are too large and are mounted on top of the cleaning machine. Each time they are inspected, employees have to climb up and down. Placing the fan unit 5 on one side of the frame 1 makes maintenance more convenient and eliminates the need for employees to climb up and down, thus ensuring their personal safety.

[0033] The blower unit 5 uses a blower of model H-10, H-15, or H-30. Compared with traditional blowers, this blower is smaller in size, occupies less space, and will not obstruct employees' movement. The rated voltage is 380V, the drive method is high-speed variable frequency permanent magnet drive, the cooling method is air cooling, the rated power is 10KW, 15KW, or 30KW, the maximum speed is 20000r / min, 18000r / min, or 16000r / min, the pressure is 22kpa, 15kpa, or 20kpa, and the flow rate is 28m3 / min, 62m3 / min, or 105m3 / min. Because the impeller of the blower rotates at high speed, it compresses air and forms a high air pressure. In the process of compressing air, heat is inevitably generated. Therefore, this blower produces hot air, eliminating the need for heating equipment and making the blower more energy-efficient. The blower unit 5 delivers airflow to the first air knife 3.12, the upper air knife 4.1, and the lower air knife 4.2.

[0034] A water return device 6 is provided on the other side of the frame 1. The water return device 6 supplies water to the cleaning device 3, such as... Figure 13 As shown, the water return device 6 includes a water tank 6.1 with an open upper side. At least one second baffle 6.2 is connected inside the water tank 6.1. In this embodiment, there are two second baffles 6.2, which divide the water tank 6.1 into three water storage tanks 6.3. A water pump 6.4 is connected to each water storage tank 6.3. The water pump 6.4 is connected to the corresponding vertical pipe 3.6 through a connecting pipe 6.5. A filter element 6.6 is provided on the upper side of each water storage tank 6.3. The filter element 6.6 includes a rectangular frame, and a filter screen is connected to the bottom of the rectangular frame to filter dirty water.

[0035] like Figure 14As shown, the connecting pipe 6.5 includes a water pipe connected to the outlet of the water pump 6.4. The water pipe is connected to the main pipe 6.52 and the backup pipe 6.53 via a three-way ball valve 6.51. A filter 6.54 is connected to the main pipe. The filter 6.54 is an existing device. The main pipe 6.52 and the backup pipe 6.53 are connected to the first output pipe 6.56 via a three-way ball valve 6.55. One of the first output pipes 6.56 is connected to two second output pipes 6.57 via a three-way connector. The two second output pipes 6.57 and the other two first output pipes 6.56 are connected to the corresponding vertical pipes 3.6. Normally, the water pump 6.4 draws water from the water storage tank 6.3, which is then filtered by the filter 6.54 before being sent into the vertical pipes 3.6. When the filter 6.54 is being repaired, the water in the water storage tank 6.3 is discharged through the backup pipe 6.53 via the three-way ball valves 6.51 and 6.55.

[0036] The water tank 6.1 also has a water inlet pipe. When the water level in the water tank 6.1 drops to a certain level, water is pumped into the water inlet pipe to replenish the water tank 6.1.

[0037] Each cleaning tank has a first water outlet at the bottom, and a first drainage component 7 is connected to the lower side of each first water outlet. The first drainage component 7 is configured to cooperate with the return water device 6. A second water outlet is provided at the bottom of the cleaning tank 3.3, and a second drainage component 9 is connected to the lower side of the second water outlet. The second drainage component 9 is configured to cooperate with the return water device 6.

[0038] The first drainage component 7 and the second drainage component 9 have the same structure, such as Figure 10 and Figure 11 As shown, they all include a water outlet pipe 7.1, which is connected to the corresponding first water outlet. The water outlet pipe 7.1 can be funnel-shaped or rectangular. In this embodiment, the water outlet pipe 7.1 of the first drainage component 7 is a funnel-shaped pipe, and the water outlet pipe 7.1 of the second drainage component 9 is a rectangular pipe structure. A water receiving component 7.2 is slidably connected to the opening of the water outlet pipe 7.1. The water receiving component 7.2 includes a rectangular box with an open top. L-shaped slide rails 7.3 are connected to both sides of the opening of the water outlet pipe 7.1. Hooks 7.4 are connected to the upper two sides of the rectangular box. The hooks 7.4 are attached to and slide on the corresponding L-shaped slide rails 7.3. The sliding of the hooks 7.4 on the L-shaped slide rails 7.3 allows the rectangular box to move, thereby changing the position of the water outlet. A circular outlet pipe 7.5 is connected to the lower side of the rectangular box. The circular outlet pipe 7.5 is set on the upper side of the corresponding filter element 6.6, so that the discharged water is filtered by the filter element 6.6 and returned to the water storage tank 6.3 for reuse, thus saving water resources.

[0039] In use, the glass plate is conveyed by the conveying component 2. The glass is then initially cleaned and dried by the preliminary cleaning mechanism. Then, the glass plate is sprayed and scrubbed by the first spraying component 3.2 and the cleaning roller assembly 3.9. After cleaning, the glass plate enters the drying area, where a set of upper air knives 4.1 and a set of lower air knives 4.2 blow the water off the upper and lower sides of the glass plate, thus completing the cleaning of the glass plate.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
