Technical Field
[0001] This utility model relates to a picture frame cleaning device, and more particularly to a cleaning device for removing dust from the surface of a picture frame. Background Technology
[0002] Picture frames are common home decorations. Most picture frames on the market are made of wood or similar materials. Due to the limitations of this material, these frames cannot be soaked or washed after production and assembly. They require manual cleaning with a small brush along the surface of the frame. To avoid damaging the coating, soft-bristled brushes are generally used. However, because the bristles are soft, they are difficult to control during manual cleaning, making it hard to reach deeper, narrower grooves in the frame. This results in dust and impurities not being removed, and it's difficult to ensure every area is thoroughly cleaned, leading to poor overall cleaning results. Therefore, cleaning existing wooden picture frames often results in ineffective cleaning. Utility Model Content
[0003] The purpose of this invention is to provide a cleaning device for removing dust from the surface of picture frames. This invention has the advantage of good cleaning effect.

Conveyor chains are installed on both sides of the groove on the base, and each conveyor chain is connected to a drive device for moving the conveyor chain. Multiple movable seats for placing the picture frame shell are arranged between two conveyor chains, and each movable seat has a through slot in the middle for the lifting device to pass through. A gantry frame is installed directly above the groove, and a pushing device is installed on the gantry frame for driving the dust collection hood up and down. By utilizing the annular air duct and the dust collection hood in conjunction, rapid and comprehensive dust removal and cleaning of all parts of the picture frame shell can be achieved, improving both cleaning speed and cleaning effect. The conveyor chains, drive devices, and movable seats can automatically move the picture frame shell on the base, eliminating the need for extensive manual operation and reducing labor intensity.
[0005] In the aforementioned cleaning device for removing dust from the surface of a picture frame, a plurality of annularly distributed baffles are provided on the top surface of the movable base, and all baffles are set on the outer circumference of the through groove; the height of each baffle is less than the height of the picture frame, and the distance from each baffle to the center of the movable base is less than the radius of the dust suction hood; the baffles can limit and fix the position of the picture frame shell on the movable base from the outside, preventing the picture frame shell from moving or falling off during cleaning or moving, thus improving the stability of the operation.
[0006] In the aforementioned cleaning device for removing dust from the surface of a picture frame, the top surface of the movable base is provided with a plurality of evenly distributed slots; the bottom surface of the stop is provided with inserts that cooperate with the slots; the slots on the movable base and the inserts on the stop allow the position of the stop on the movable base to be adjusted autonomously according to the size of the picture frame shell to be cleaned, thereby improving the flexibility of use.
[0007] In the aforementioned cleaning equipment for removing dust from the surface of a picture frame, the lifting device includes two symmetrically distributed servo motors, each servo motor being connected to a ball screw; each ball screw is slidably mounted with a nut seat, and each nut seat has an "L"-shaped mounting seat on its side, with a lifting plate between the two mounting seats; the annular air duct is located on the top surface of the lifting plate.
[0008] In the aforementioned cleaning device for dust removal from the surface of a picture frame, a first magnet is provided on the top surface of the mounting base; a second magnet that cooperates with the first magnet is provided on the bottom surface of the lifting plate; by providing a first magnet on the mounting base and a second magnet on the lifting plate, the connection stability between the lifting plate and the mounting base is ensured, and the lifting plate can be removed from both mounting bases, thereby facilitating the maintenance of the annular duct.
[0009] In the aforementioned cleaning device for removing dust from the surface of a picture frame, the driving device includes a drive sprocket and a driven sprocket respectively disposed at both ends of the conveyor chain. A drive motor is connected to the drive sprocket, and a reducer is disposed between the drive motor and the drive sprocket.
[0010] In the aforementioned cleaning equipment for removing dust from the surface of a picture frame, an infrared sensor is installed on the top surface of the base at the position between the groove and the conveyor chain; the lifting device, the pushing device, and the driving device are all electrically connected to the infrared sensor; a sensing block that cooperates with the infrared sensor is installed on the bottom surface of each moving seat; by installing an infrared sensor on the base and cooperating with the sensing block installed on the bottom surface of the moving seat, the purpose of automatically controlling the operation of the lifting device, the annular air duct, the pushing device, and the driving device can be realized, thereby improving work efficiency.
[0011] In the aforementioned cleaning equipment for removing dust from the surface of a picture frame, the pushing device includes a push-out cylinder disposed on the top surface of the gantry frame, and a push-out seat connected to the push-out cylinder; the dust suction hood is disposed on the push-out seat; and a retractable dust suction pipe is provided between the dust suction hood and the dust suction fan.
[0012] In the aforementioned cleaning device for removing dust from the surface of a picture frame, the movable seat is made of elastic rubber material.
[0013] Compared with existing technologies, this utility model improves upon existing picture frame surface cleaning devices. By incorporating a dust suction hood and an annular air duct on the base, along with a through-slot in the center of the moving seat for the annular air duct to pass through, the conveyor chain stops moving when it transports the moving seat and the picture frame shell directly above the slot. The annular air duct then passes through the through-slot on the moving seat and enters the inside of the picture frame shell, allowing for omnidirectional airflow inside the frame. This quickly blows up dust from various locations on the picture frame surface. Combined with the dust suction hood and vacuum fan, the blown dust can be collected and processed. This design improves both cleaning effectiveness and efficiency. A lifting device within the groove allows the annular duct to move up and down, ensuring both proper cleaning operation and stable movement of the cleaned picture frame. Furthermore, two conveyor chains, each connected to a drive unit, and multiple evenly distributed movable seats between the chains, automatically move the picture frame on the base, eliminating the need for extensive manual operation and reducing labor intensity.
[0014] Furthermore, this invention features multiple evenly distributed stops on the top surface of the movable base. These stops effectively limit and fix the position of the picture frame shell on the movable base from the outside, preventing the shell from shifting or falling during cleaning or movement, thus improving operational stability. The slots on the movable base and the inserts on the stops allow for independent adjustment of the stops' positions on the movable base according to the size of the picture frame shell to be cleaned, thereby increasing flexibility. The presence of a first magnet on the mounting base and a second magnet on the lifting plate ensures stable connection between the lifting plate and the mounting base while also allowing the lifting plate to... The device can be removed from the two mounting bases, facilitating maintenance of the annular duct. A reducer between the drive motor and the drive sprocket allows for better control of the conveyor chain's speed, simplifying operation. An infrared sensor on the base, working in conjunction with a sensing block on the bottom of the moving base, automatically controls the lifting device, annular duct, pushing device, and drive device when the moving base is directly above the groove, improving work efficiency. A retractable suction pipe between the dust hood and the suction fan ensures stable movement of the dust hood, guaranteeing effective cleaning. Therefore, this invention not only provides excellent cleaning results but also boasts advantages such as high cleaning efficiency, high operational stability, convenient maintenance, low labor intensity, and high flexibility.

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0023] Example. A cleaning device for removing dust from the surface of a picture frame, comprising as follows: Figures 1 to 6 As shown, the device includes a base 1, a dust collection hood 2, and a dust collection fan 3 connected to the dust collection hood 2. The base 1 has a groove 4 in the middle, and a lifting device is installed in the groove 4. The lifting device is equipped with an annular air duct 5, and multiple annularly distributed air outlets 6 are provided on the outer surface of the annular air duct 5. Conveyor chains 7 are installed on the base 1 at positions corresponding to both sides of the groove 4, and each conveyor chain 7 is connected to a drive device for moving the conveyor chain 7. Multiple movable seats 8 for placing the picture frame shell are arranged between two conveyor chains 7, and each movable seat 8 has a through groove 9 in the middle for the lifting device to pass through. A gantry frame 10 is arranged directly above the groove 4, and a pushing device for driving the dust collection hood 2 to move up and down is provided on the gantry frame 10.
[0024] The top surface of the movable base 8 is provided with multiple annularly distributed baffles 11, all of which are located on the outer circumference of the through groove 9. The height of each baffle 11 is less than the height of the picture frame, and the distance from each baffle 11 to the center of the movable base 8 is less than the radius of the dust collection hood 2. The top surface of the movable base 8 is provided with multiple evenly distributed slots 12. The bottom surface of each baffle 11 is provided with a plug 13 that mates with the slot 12. The lifting device includes two symmetrically distributed servo motors 14, each servo motor 14 is connected to a ball screw 15. Each ball screw 15 is slidably mounted with a nut seat, and each nut seat has an "L"-shaped mounting seat 16 on its side. A lifting plate 17 is provided between the two mounting seats 16. The annular air duct 5 is located on the top surface of the lifting plate 17. A first magnet 18 is provided on the top surface of the mounting seat 16. The bottom surface of the lifting plate 17 is provided with... A second magnet 19 is provided to cooperate with the first magnet 18; the driving device includes a drive sprocket 20 and a driven sprocket 21 respectively disposed at both ends of the conveyor chain 7, a drive motor 22 is connected to the drive sprocket 20, and a reducer 23 is provided between the drive motor 22 and the drive sprocket 20; an infrared sensor 24 is provided on the top surface of the base 1 at the position corresponding to the groove 4 between the conveyor chain 7; the lifting device, the pushing device and the driving device are all electrically connected to the infrared sensor 24; a sensing block 25 cooperating with the infrared sensor 24 is provided on the bottom surface of each movable seat 8; the pushing device includes a push cylinder 26 disposed on the top surface inside the gantry frame 10, and a push seat 27 is connected to the push cylinder 26; a dust suction hood 2 is disposed on the push seat 27; a retractable dust suction pipe 28 is provided between the dust suction hood 2 and the dust suction fan 3; the movable seat 8 is made of elastic rubber material.
[0025] Working principle: During the cleaning process, the picture frame shell to be cleaned is first placed on the movable base 8. A stopper 11 is inserted into the slot 12 closest to the outer edge of the picture frame shell, according to its size. The stopper 11 limits the position of the picture frame shell from the outside, preventing it from shifting and blocking the through slot 9 or falling off the movable base 8 during subsequent movement, thus ensuring the stability of the subsequent work. Then, the entire device is connected to an external safe mains power supply, activating the infrared sensor 24 (the infrared sensor used in this invention...). The sensor 24 can specifically be a PIS209, LHI878, or SE2470, etc., which then controls the two drive motors 22 to start. After the drive motors 22 start, they will drive the drive sprocket 20 to rotate. After the drive sprocket 20 rotates, it will drive the conveyor chain 7 to move. After the conveyor chain 7 moves, it will drive the driven sprocket 21 to rotate. After both the driven sprocket 21 and the drive sprocket 20 rotate, the conveyor chain 7 will move in a cycle. During the movement of the conveyor chain 7, it will drive the moving seat 8 to move towards the groove 4. During the movement of the moving seat 8, it will drive the picture frame shell to move together.
[0026] When the conveyor chain 7 moves the movable seat 8 and the picture frame shell on the movable seat 8 to directly above the groove 4, the sensing block 25 on the bottom surface of the movable seat 8 will sense the infrared sensor 24 on the base 1, causing the infrared sensor 24 to send a signal to the controller (which can be a programmable controller such as FX2C-20MRD, Cortex-R8, or Cortex-M7) located on the side of the base 1. After receiving the signal from the infrared sensor 24, the controller will first control the drive motor 22 to stop. After the drive motor 22 stops, the drive sprocket 20 will stop rotating, thereby stopping the conveyor chain. When the servo motor 7 and the movable seat 8 stop rotating, the outer shell of the picture frame can be stably and accurately positioned directly above the groove 4. Then, the servo motor 14, the ejector cylinder 26, and the vacuum fan 3 are started for a certain period of time. At the same time, the external blower connected to the annular duct 5 is started, so that there is flowing air inside the annular duct 5. When the servo motor 14 starts, it drives the ball screw 15 to rotate. The rotation of the ball screw 15 drives its own nut seat movable seat 8 to move in a certain direction. During the movement of the nut seat, the mounting seat 16 moves together with it. During the movement of the mounting seat 16, the lifting plate 17 moves together with it. Finally, the lifting plate 17 moves the annular duct 5 upward together. The annular air duct 5, located on one side of the frame shell via the through-slot 9 (in its final state, the top surface of the annular air duct 5 will be above the top surface of the frame shell, and the bottom surface of the annular air duct 5 will be on the same horizontal plane as the bottom surface of the frame shell), blows air from the inside of the frame shell outwards using multiple evenly distributed annular air nozzles 6 on the annular air duct 5, thereby blowing away dust and impurities on the frame shell. When the ejector cylinder 26 is activated, it pushes the ejector seat 27 towards the top surface of the base 1. During the movement of the ejector seat 27, the dust collection hood 2 moves along with it, ultimately causing the bottom surface of the dust collection hood 2 to contact the top surface of the moving seat 8, completely enclosing the frame shell inside the dust collection hood 2. After the dust blower 3 is started, it will suck the air out of the dust hood 2 through the dust suction pipe 28, thereby creating a negative pressure inside the dust hood 2. This allows the dust hood 2 to suck the surrounding dust and impurities into the dust suction pipe 28 and discharge them out of the dust suction pipe 28 for centralized treatment. By using the dust hood 2 and the annular air duct 5 in conjunction, the surface of the picture frame can be cleaned quickly and thoroughly. After cleaning is completed, the dust blower 3, the annular air duct 5 and the push cylinder 26 are stopped, the servo motor 14 is started in reverse, and after the push cylinder 26 stops, it will drive the dust hood 2 to move upward through the push seat 27, thereby separating the dust hood 2 from the moving seat 8.After the servo motor 14 starts in reverse, it drives the ball screw 15 to rotate in the opposite direction. This rotation of the ball screw 15 then moves the lifting plate 17, mounting base 16, and annular air duct 5 towards the bottom surface of the groove 4. Ultimately, the lifting plate 17 moves through the through slot 9 to below the bottom surface of the moving base 8. Once the lifting plate 17 and dust hood 2 have returned to their initial positions, the drive motor 22 is started again for a certain period. The drive motor 22 then drives the conveyor chain 7 to circulate again. This movement of the conveyor chain 7 moves the cleaned picture frame shell from above the groove 4 to one side, allowing the next picture frame shell to be cleaned to be moved directly above the groove 4 for further cleaning.
