Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to an air blowing cleaning and dust removal device. Background Technology

[0002] Pallets are typically used as transport containers for products. After being used repeatedly on the production line, pallets accumulate dust and other foreign matter, necessitating cleaning. Currently, dust adhering to pallets is removed manually, leading to reduced cleaning efficiency and consequently lower production productivity. Therefore, further improvements are needed. Utility Model Content

[0003] To improve the cleaning efficiency of pallets, this application provides an air-blowing cleaning and dust removal device.

[0004] The air-blowing cleaning and dust removal device provided in this application adopts the following technical solution:

[0005] An air-blowing cleaning and dust removal device includes a frame, a conveyor belt for conveying a pallet, an upper cleaning mechanism located above the conveyor belt for air-blowing cleaning of the upper surface of the pallet, and an exhaust mechanism for extracting air from the air-blowing cleaning area.

[0006] By adopting the above technical solution, the pallet is placed on the conveyor belt. When the conveyor belt passes the upper cleaning mechanism, the upper cleaning mechanism blows air to clean the upper surface of the pallet to improve the cleanliness of the upper surface of the pallet. The dust blown up is drawn away by the exhaust mechanism, reducing the possibility of dust re-attaching to the pallet after flying.

[0007] Preferably, the frame is provided with an electrostatic eliminator located upstream of the upper cleaning mechanism to eliminate static electricity from the tray.

[0008] Preferably, the static eliminator is an ionizer bar.

[0009] By adopting the above technical solution, the ion bar generates a large amount of airflow with positive and negative charges, which is blown out at high speed by compressed air to neutralize the charge on the tray, thereby eliminating static electricity on the tray, reducing the adhesion of dust, and making the dust attached to the tray easier to clean.

[0010] Preferably, the conveyor belt is a mesh conveyor belt, and the frame is provided with a lower cleaning mechanism for blowing air to clean the lower surface of the pallet.

[0011] By adopting the above technical solution, when the pallet passes through the lower cleaning mechanism, the lower cleaning mechanism blows air to clean the lower surface of the pallet, thereby improving the cleanliness of the lower surface of the pallet.

[0012] Preferably, the upper cleaning mechanism includes a first upper air knife disposed on the frame, the length direction of the first upper air knife being parallel to the width direction of the conveyor belt.

[0013] By adopting the above technical solution, the air knife generates a high-speed rotating airflow jet that passes through a special flow channel or nozzle outlet, forming a high-speed airflow shear boundary at the outlet, thereby generating strong shearing force to blow away and separate the dust adhering to the tray.

[0014] Preferably, the upper cleaning mechanism further includes a second upper air knife that slides along the width direction of the conveyor belt and is connected to the frame. The length direction of the second upper air knife is parallel to the length direction of the conveyor belt. The frame is provided with an air knife driving mechanism that drives the second upper air knife to reciprocate and slide.

[0015] By adopting the above technical solution, the first and second upper air knives work together to blow air and clean different directions on the upper surface of the pallet, thereby improving cleaning efficiency. The air knife driving mechanism drives the second upper air knife to move so as to blow air and clean different positions on the upper surface of the pallet.

[0016] Preferably, the air knife driving mechanism includes a rodless cylinder fixedly connected to the frame and located above the conveyor belt, and a sliding seat fixedly connected to the slider of the rodless cylinder. The length direction of the rodless cylinder is parallel to the width direction of the conveyor belt, and the second upper air knife is disposed on the sliding seat.

[0017] By adopting the above technical solution, the sliding seat is driven to slide by a rodless cylinder, thereby driving the second upper air knife to slide.

[0018] Preferably, the sliding seat includes a vertical plate fixedly connected to the slider of the rodless cylinder and a horizontal plate fixedly connected to the lower part of the vertical plate. The second upper air knife is fixedly connected to the horizontal plate. The frame is provided with a dust cover covering the rodless cylinder. The lower part of the dust cover has an opening for the vertical plate to slide out.

[0019] By adopting the above technical solution, a dust cover is added to the rodless cylinder, which effectively reduces the possibility of blowing dust adhering to the rodless cylinder.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. Place the pallet on the conveyor belt. When the conveyor belt passes the upper cleaning mechanism, the upper cleaning mechanism blows air to clean the upper surface of the pallet to improve the cleanliness of the upper surface of the pallet. The dust blown up is drawn away by the exhaust mechanism to reduce the possibility of dust re-adhering to the pallet after flying.

[0022] 2. When the pallet passes through the lower cleaning mechanism, the lower cleaning mechanism blows air to clean the lower surface of the pallet to improve the cleanliness of the lower surface of the pallet;

[0023] 3. The first and second upper air knives work together to blow air and clean different directions on the upper surface of the pallet, improving cleaning efficiency. The air knife drive mechanism drives the second upper air knife to move so as to blow air and clean different positions on the upper surface of the pallet. Attached Figure Description

Detailed Implementation

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] This application discloses an air-blowing cleaning and dust removal device, referring to... Figure 1 , Figure 2 The system includes a frame 1, to which a conveyor belt 2 for transporting pallets is rotatably connected. The length direction of the conveyor belt 2 is parallel to the length direction of the frame 1. In this embodiment, four conveyor frames 11 are fixedly connected to the frame 1 and distributed along the length direction of the frame 1. Four sets of conveyor belts 2 are correspondingly arranged and rotatably connected to the conveyor frames 11. Each set of conveyor belts 2 is a mesh conveyor belt 2. The two sets of conveyor belts 2 at the beginning and end are the loading station and the unloading station, respectively, and the two sets of conveyor belts 2 in the middle are the cleaning station. Pallets can be transported sequentially at the loading station, the cleaning station, and the unloading station.

[0031] Reference Figure 1 , Figure 3A cleaning housing 12 is fixedly connected to the middle of the upper surface of the frame 1. The lower part of the cleaning housing 12 is open. The cleaning housing 12 is located above the cleaning station. Both sides of the cleaning housing 12 have openings for the pallet to pass through. An electrostatic eliminator is provided on the outer wall of the cleaning housing 12 near the loading station to eliminate static electricity from the pallet. The electrostatic eliminator is an ion air bar 3 fixedly connected to the outer wall of the cleaning housing 12 near the loading station. The ion air bar 3 is located above the openings, and the air outlet of the ion air bar 3 is oriented downwards.

[0032] Reference Figure 2 , Figure 4 The cleaning housing 12 has an upper cleaning mechanism 4 for blowing air to clean the upper surface of the tray and a lower cleaning mechanism 5 for blowing air to clean the lower surface of the tray. The lower cleaning mechanism 5 is a lower air knife, which is located between the conveyor belts 2 of the two cleaning stations. The air outlet of the lower air knife faces upward, the length direction of the lower air knife is parallel to the width direction of the conveyor belt 2, and the upper surface of the lower air knife is lower than the upper surface of the conveyor belt 2.

[0033] The upper cleaning mechanism 4 includes a first upper air knife 41 and a second upper air knife 42, both with their air outlets facing downwards. The length direction of the first upper air knife 41 is parallel to the width direction of the conveyor belt 2, and the first upper air knife 41 is located above the conveyor belt 2 at the cleaning station near the loading station. The first upper air knife 41 is fixed to the conveyor frame 11 at the cleaning station by a bracket. The length direction of the second upper air knife 42 is parallel to the length direction of the conveyor belt 2, and the second upper air knife 42 is located above the conveyor belt 2 at the cleaning station near the unloading station.

[0034] Reference Figure 2 , Figure 4 The cleaning housing 12 is equipped with an air knife drive mechanism 6 that drives the second upper air knife 42 to reciprocate. The air knife drive mechanism 6 includes a rodless cylinder 61 fixedly connected to the inner wall of the cleaning housing 12 near the unloading station and located above the conveyor belt 2, and a sliding seat 62 fixedly connected to the slider of the rodless cylinder 61. The length direction of the rodless cylinder 61 is parallel to the width direction of the conveyor belt 2. The sliding seat 62 includes a vertical plate 621 fixedly connected to the slider of the rodless cylinder 61 and a horizontal plate 622 fixedly connected to the lower part of the vertical plate 621. The second upper air knife 42 is fixedly connected to the horizontal plate 622. The cleaning housing 12 is fixedly connected with a dust cover 63 covering the rodless cylinder 61. The lower part of the dust cover 63 has an opening for the vertical plate 621 to slide out.

[0035] The frame 1 is equipped with an exhaust mechanism 7 for extracting air from the air-blowing cleaning area. The exhaust mechanism 7 includes a first upper exhaust hood 71 fixedly built into the cleaning housing 12 and covering the first upper air knife 41, a second upper exhaust hood 72 fixedly connected to the horizontal plate 622 and covering the second upper air knife 42, a first lower exhaust hood 73 fixedly connected to the frame 1 and located below the conveyor belt 2 of one of the cleaning stations, a second lower exhaust hood 74 fixedly connected to the frame 1 and located below the conveyor belt 2 of the other cleaning station, and an exhaust fan 75 fixedly connected to the frame 1. The first upper exhaust hood 71, the second upper exhaust hood 72, the first lower exhaust hood 73, and the second lower exhaust hood 74 are all connected to the exhaust fan 75 through pipes.

[0036] The implementation principle of the air-blowing cleaning and dust removal device in this application embodiment is as follows: The tray to be cleaned is placed on the conveyor belt 2 of the loading station. When the tray passes under the ion bar 3, the ion bar 3 generates a large amount of airflow with positive and negative charges, which is blown out at high speed by compressed air to neutralize the charge on the tray, thereby eliminating static electricity on the tray and reducing the adhesion of dust. After the tray continues to be conveyed into the cleaning chamber 12, it first passes through the first upper air knife 41 and the lower air knife in sequence. The first upper air knife 41 and the lower air knife respectively perform transverse air-blowing cleaning on the upper and lower surfaces of the tray. Next, the second upper air knife 42 is driven by the rodless cylinder 61 to slide the sliding seat 62, thereby driving the second upper air knife 42 to slide longitudinally. The second upper air knife 42 performs longitudinal air blowing cleaning on the upper surface of the pallet. The first upper air knife 41 and the second upper air knife 42 respectively perform air blowing cleaning on different directions of the upper surface of the pallet, improving cleaning efficiency and cleaning effect. During the air blowing cleaning process, the dust blown up is drawn away by the exhaust mechanism 7, reducing the possibility of dust re-attaching to the pallet after flying. Finally, the cleaned pallet is conveyed away by the conveyor belt 2 of the unloading station.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
