Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to an intelligent automatic drape replacement system for a dental workbench. Background Art

[0002] During dental treatment, disposable drapes are usually placed on the dental workbench to keep the operating surface clean and hygienic. However, most existing dental workbenches rely on manual replacement of drapes, which is time-consuming and labor-intensive, and may increase the risk of cross-contamination. Especially in a high-intensity diagnosis and treatment environment, frequent contact and replacement of drapes can easily lead to the spread of bacteria and viruses, posing a potential threat to the health of medical staff and patients.

[0003] Some existing technologies attempt to achieve semi-automatic drape laying by adding a simple roller structure, but these designs have many deficiencies in practical applications. First, due to the lack of an automated cutting function, drapes can only be replaced as a whole roll, and it is difficult to automatically cut and collect them after use; second, most existing automatic drape laying devices have a simple structure and lack an effective tensioning and guiding mechanism, which can easily lead to uneven drape unfolding, wrinkles or misalignment, affecting the comfort and efficiency of operation. In addition, the recycling of discarded drapes also requires manual processing, further increasing the workload and pollution risk.

[0004] In short, the existing dental table drape replacement device cannot achieve efficient, intelligent, and automatic drape replacement and recycling, and it is difficult to meet the high requirements of modern dental treatment for hygiene and convenient operation. Therefore, there is an urgent need for a new type of automated drape replacement system that can automatically lay, cut, and recycle drapes, improve replacement efficiency, and reduce the risk of cross contamination, so as to better meet the needs of dental treatment scenarios.

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0026] like Figure 1-9 As shown, the present invention provides an intelligent dental table drape automatic replacement system, including a table body 1, a drape 2 that can be moved left and right is arranged in the middle of the table body 1, and is used to cover the work surface to keep it clean. A winding shaft 3 is arranged on the left side of the table body 1, and the drape 2 is wound around the outer periphery of the winding shaft 3, which is convenient for the orderly unfolding of the drape. The rotation of the winding shaft 3 is powered by a power motor 7, and the power motor 7 is meshed and connected with the relay gear shaft 5 and the reversing gear shaft 8 through the power gear 6 to form a stable transmission system. The relay gear shaft 5 is coaxially fixed with the winding shaft 3 through the winding gear 4, so that the winding shaft 3 can rotate under the drive of the power motor 7, ensuring the smooth supply of the drape 2.

[0027] The left and right sides of the platform 1 are provided with guide devices for guiding the movement of the drape 2. The guide devices include a drape discharging roller 11 and a drape collecting roller 19. The drape discharging roller 11 is installed on the left side of the platform 1, and is meshed and connected by the drape discharging lower gear shaft 9 and the drape discharging upper gear shaft 10, driving the drape 2 to gradually unfold from the winding shaft 3 and maintain its tension state. The drape discharging lower gear shaft 9 and the drape discharging upper gear shaft 10 are both rotatably connected to the inside of the platform 1, and the two are connected to the reversing roller shaft 13 through the drape discharging belt 12, so that the drape 2 can move smoothly under the guidance of the drape discharging roller 11.

[0028] A cutting device is installed on the right side of the table body 1, and the cutting device includes a cutting seat 20, a cutting knife 21 and a cutting telescopic rod 22. When the drape 2 reaches a predetermined length, the cutting telescopic rod 22 pushes the cutting knife 21 to move up and down to cut the drape 2 for subsequent recycling. A cutting bottom plate 26 is fixed below the cutting seat 20 to provide stable support.

[0029] A recycling device is provided on the right side of the cutting device for collecting the discarded drapes 2. The recycling device includes a trash bin 23, in which a top pressure plate 25 and a side push plate 24 are provided. The top pressure plate 25 is driven by a top pressure telescopic rod 28, and the side push plate 24 is controlled by a side push telescopic rod 27. The two cooperate to compress the discarded drapes 2 to the bottom of the trash bin 23, thereby reducing the volume of the waste and facilitating cleaning and recycling.

[0030] A power motor 7 is fixedly connected to the left side of the platform 1, and a power gear 6 is fixed to the rotating shaft of the power motor 7. The left and right sides of the power gear 6 are respectively meshed with a relay gear shaft 5 and a reversing gear shaft 8 to achieve power transmission. The relay gear shaft 5 and the reversing gear shaft 8 are both rotatably connected to the inside of the platform 1 through bearings to ensure a smooth and efficient transmission process.

[0031] The relay gear shaft 5 is meshedly connected with the winding gear 4, the winding gear 4 and the winding shaft 3 are coaxially fixedly connected, and the winding shaft 3 can be rotatably connected to the inside of the platform 1 to facilitate the unfolding and supply of the drape 2. The winding shaft 3 is used to accommodate and supply the drape 2 wound on the periphery, and driven by the power motor 7, the drape 2 is gradually released through the transmission system to provide source power for laying and guiding.

[0032] The reversing gear shaft 8 is meshed with the lower towel discharging gear shaft 9, and the lower towel discharging gear shaft 9 continues to mesh with the upper towel discharging gear shaft 10, forming a stable transmission match. The guide device is composed of a towel discharging roller 11 and a towel collecting roller 19 on the left and right sides. The towel discharging roller 11 is coaxially fixed with the lower towel discharging gear shaft 9 and the upper towel discharging gear shaft 10, respectively, to ensure that the position of the towel 2 in the guide device is stable and kept flat.

[0033] The left side of the table 1 is also rotatably connected to a reversing roller shaft 13, which is connected to the lower gear shaft 9 of the towel outlet through a pulley, and each pulley is driven by the towel outlet belt 12 to achieve synchronous movement. The drape 2 passes through the drape outlet rollers 11, passes over the reversing roller shaft 13, and extends from the left side of the table 1 to the laying area. This design can effectively prevent the drape 2 from being misaligned during movement, ensure the flatness of the laying, and keep the drape 2 properly tensioned during the entire use process, ensuring the cleanliness of the operation area and the smooth replacement of the drape.

[0034] The right side of the platform 1 is rotatably connected to a towel collecting roller shaft 15, and a pulley groove is opened in the middle of the outer circumference of the towel collecting roller shaft 15, corresponding to the left reversing roller shaft 13. The reversing roller shaft 13 also has a pulley groove, and the two are connected by a linkage belt 14, and the linkage belt 14 is located in the pulley groove, so as to realize the synchronous rotation of the two roller shafts. This design ensures the stability of the drape 2 during the transmission process, and effectively prevents the drape from being misplaced or slipped during the transmission.

[0035] The main function of the towel collecting roller shaft 15 is to cooperate with the towel collecting lower gear shaft 17 and the towel collecting upper gear shaft 18 to gradually guide the towel 2 to the cutting device on the right side of the platform 1, ensuring that the towel can smoothly enter the cutting position after reaching the predetermined length. The towel collecting roller 19 and the towel discharging roller 11 have similar structures, and both are driven by belts to achieve synchronous rotation, so that the towel maintains appropriate tension and stability during the entire movement process, thereby ensuring the laying effect.

[0036] The setting of the linkage belt 14 ensures that the drape 2 moves smoothly from the left side to the right side of the table body and maintains appropriate tension. Through the coordinated transmission of the drape collection roller shaft 15 and the reversing roller shaft 13, the drape 2 is smoothly and continuously unfolded from the winding shaft 3 to the cutting device during the entire laying process, avoiding wrinkles or looseness, and ensuring the quality and neatness of the laying. This structural design effectively reduces the complexity of the operation when replacing the drape, making the entire automatic replacement system more reliable and efficient.

[0037] The right inner side of the platform 1 is rotatably connected with a lower towel collection gear shaft 17 and an upper towel collection gear shaft 18, which are connected by gear meshing to form a stable power transmission relationship. The lower towel collection gear shaft 17 and the upper towel collection gear shaft 18 are coaxially fixedly connected to the corresponding towel collection roller 19, respectively, so as to ensure that the towel 2 can move smoothly along the predetermined path during the transmission process to avoid deviation or wrinkles.

[0038] In addition, the lower towel collecting gear shaft 17 and the towel collecting roller shaft 15 are coaxially fixedly connected with pulleys, and these pulleys are connected through the towel collecting belt 16 to form a reliable transmission system. When the towel collecting roller shaft 15 rotates, the lower towel collecting gear shaft 17 is driven by the towel collecting belt 16, so that the towel collecting roller 19 rotates synchronously. This design further ensures the transmission stability of the towel 2, so that it can maintain appropriate tension during the entire transmission process, thereby achieving a smooth laying effect.

[0039] The drape 2 passes from the outside of the table 1 over the drape collection roller shaft 15, passes between the drape collection rollers 19, and is then transferred to the area of ​​the cutting device 20, waiting for the subsequent automatic cutting operation. This transmission path design allows the drape 2 to be unfolded from left to right in sequence, smoothly passing through each guide and transmission component, thereby ensuring accurate control of the cutting position and preparing for the next drape replacement. The combination of the drape collection roller 19 and the drape collection roller shaft 15 not only effectively supports the movement of the drape 2, but also ensures the flatness and position stability of the drape when it reaches the cutting device 20, improving the overall reliability and operating efficiency of the system.

[0040] The cutting device includes a cutting seat 20 fixed inside the table 1. The cutting seat 20 serves as a fixed support structure for the entire cutting operation to ensure the stability of the cutting process. A cutting knife 21 that can move up and down is slidably connected to the upper side of the cutting seat 20. The up and down sliding of the cutting knife 21 enables it to accurately cut the drape 2, ensuring that each cutting can be completed at the predetermined position. The design of the cutting knife 21 is easy to maintain and replace, ensuring the durability of the system and the stability of the cutting effect.

[0041] The upper part of the cutting seat 20 is fixedly connected with a cutting telescopic rod 22, which is driven to extend and retract by a control signal, thereby driving the cutting knife 21 to move up and down. The end of the cutting telescopic rod 22 is fixedly connected to the cutting knife 21, so that the cutting knife 21 can achieve precise up and down movement during cutting, avoiding deviation or error during the cutting process. This design can ensure that the cutting knife 21 can quickly and accurately cut the drape 2 after it reaches the specified length, which is convenient for subsequent waste recycling.

[0042] In addition, a cutting base plate 26 is fixed to the lower side of the cutting seat 20. The cutting base plate 26 is located below the cutting knife 21 and serves as a support surface during cutting. The cutting base plate 26 can not only withstand the pressure of the cutting knife 21, but also stabilize the position of the drape 2, making the cutting more neat and smooth. The entire cutting device forms an efficient and accurate automatic cutting system through the cooperation of the cutting seat 20, the cutting knife 21, the cutting telescopic rod 22 and the cutting base plate 26, so that the drape 2 can be accurately cut after being used to a specified length, preparing for the recycling of waste and the next round of laying.

[0043] The recycling device includes a trash bin 23, which is located at the lower side of the cutting seat 20 and is used to collect and store the discarded drapes 2 after cutting so as to facilitate subsequent centralized cleaning and processing. The trash bin 23 has a reasonable design structure and can store the waste while keeping the table 1 clean and tidy, avoiding the scattering and contamination of the discarded drapes.

[0044] A side push telescopic rod 27 is fixed on the left side of the trash bin 23, and a side push plate 24 is connected to the end of the side push telescopic rod 27. The side push plate 24 is slidably connected to the inner side of the trash bin 23, and can move left and right under the drive of the side push telescopic rod 27, so as to push the waste drapes 2 that enter the trash bin 23 after being cut to a designated position, thereby ensuring that the waste can be evenly accumulated, maximizing the use of the volume of the trash bin 23, and reducing the cleaning frequency.

[0045] A pressing telescopic rod 28 is fixed to the upper right side of the trash bin 23, and the end of the pressing telescopic rod 28 is fixedly connected to the pressing plate 25. The pressing plate 25 is slidably connected to the inner side of the trash bin 23. Through the upward and downward telescopic movement of the pressing telescopic rod 28, the pressing plate 25 can compress the waste drapes 2, further reducing the volume of the waste. This compression function helps to accommodate more waste drapes 2 in the trash bin 23, thereby extending the cleaning interval and improving work efficiency.

[0046] Through the linkage of the side push telescopic rod 27 and the top pressure telescopic rod 28, the side push plate 24 and the top pressure plate 25 can work together to ensure that the waste drapes 2 are compressed and stacked in an orderly manner in the trash bin 23, preventing excessive accumulation or blockage of waste. The entire recycling device achieves efficient compression and storage of waste through the structural design of the trash bin 23, the side push plate 24, and the top pressure plate 25, ensuring the cleanliness of the operating table and the efficient operation of the recycling device.

[0047] When the device is in use, the following steps can be followed: ① When the drape 2 needs to be replaced, the power supply of the device is turned on, the system automatically enters the replacement mode, the power motor 7 starts working, and drives the winding shaft 3 to gradually unfold the drape 2. Under the coordinated action of the drape discharging roller 11, the drape collecting roller 19 and the reversing roller shaft 13 and other transmission components, the drape 2 is tightened and kept flat along a fixed path, ensuring that the drape is not wrinkled or loose when laid on the work surface. ② When the drape 2 reaches the preset replacement length, the cutting device is started, and the cutting telescopic rod 22 drives the cutting knife 21 to slide downward, cutting the drape 2 at the specified position, and the end of the drape after cutting falls into the trash can 23 located below the cutting device. ③ After the cutting is completed, the recycling device is started, and the side push telescopic rod 27 drives the side push plate 24 to remove the discarded drape after cutting. ④ After the cutting and recycling steps are completed, the new drape has been covered on the work surface, and the system returns to the initial state, waiting for the next operation requirement. ⑤ When the drape roll is about to run out or the waste in the trash bin 23 is close to being full, the system will issue a reminder to prompt the user to replace the drape roll or clean the trash bin. The user replaces or cleans it according to the prompt to ensure the continuous and efficient operation of the device.
