Description

Technical Field

[0001] This utility model relates to the field of medical protective equipment production technology, and in particular to an automatic packaging system for isolation gowns. Background Technology

[0002] With the increasing demand for medical protective equipment, the automation of isolation gown production has become an industry trend, but significant bottlenecks remain in the downstream packaging stage. Currently, although core production processes have been automated, finished product packaging still relies on manual labor for tasks such as filling, bag opening preparation, sealing, and compression. This leads to problems such as poor process coordination, unstable packaging quality, and low compression efficiency. Existing general-purpose packaging machinery generally suffers from structural redundancy, low functional integration, and complex maintenance. For example, modular design results in bulky equipment, separate subsystems for bag opening and sealing, and the risk of motion interference due to multi-cylinder linkage structures. These technical pain points severely restrict the automation upgrade of the packaging process.

[0003] While existing technologies have attempted improvements, they still suffer from issues such as insufficient bag opening positioning accuracy and high equipment costs. For example, some solutions use robotic arms to grip and support the bag, but in practical applications, a vision correction system is still required, further increasing equipment costs. To meet the demands for efficient, stable, and low-cost packaging of medical protective equipment, there is an urgent need to develop an automated packaging system that is highly integrated, easy to operate, and convenient to maintain.

Detailed Implementation

[0025] like Figure 1 As shown, an automatic packaging system for isolation gowns includes a conveying subsystem 1, a bag-supporting system 2, and a sealing subsystem 3. The conveying subsystem 1 is located at the beginning of the system and connected to the isolation gown folding system. The isolation gown folded by the isolation gown folding system is picked up and transported by the conveying subsystem 1. The sealing subsystem 3 is located at the end of the system and seals and vents the packaging bag 5. The bag-supporting system 2 is located between the conveying subsystem 1 and the sealing subsystem 3 and expands the opening of the packaging bag 5 outward and blows air into the bag to ensure that the folded isolation gown 4 can smoothly enter the packaging bag 5.

[0026] During system operation, the folded isolation gown 4 is folded by the folding system and then transported through the transmission subsystem 1. When the folded isolation gown 4 moves in front of the bag-holding system 2, the transmission subsystem 1 picks up the folded isolation gown 4 and continues to transport it forward. At the same time, the bag-holding system 2 opens the opening of the packaging bag 5 and blows air in to inflate the packaging bag 5. The transmission subsystem 1 then inserts the folded isolation gown 4 into the packaging bag 5 and continues to transport it forward until it enters the sealing subsystem 3.

[0027] After the folded isolation gown 4 and the packaging bag 5 enter the sealing subsystem 3, the sealing subsystem 3 will compress the packaging bag 5 downwards and expel the air inside the bag. Finally, the sealing subsystem 3 will seal the packaging bag 5 and complete the packaging.

[0028] Preferred solutions include Figure 2 As shown, the transmission subsystem 1 includes a transmission platform 101, inside which a transmission belt 103 is installed and connected to the front end of the isolation gown folding system. Parallel slide plates 102 are arranged on both sides of the transmission platform 101, and a sliding frame 104 is installed above the transmission platform 101. The two sides of the sliding frame 104 are engaged in the slide plates 102 and slide along the slide plates 102 for limiting. A drive motor 105 is installed on the sliding frame 104, and the drive motor 105 is connected to an external drive system. A pickup clamp 106 is connected below the drive motor 105 and clamps the folded isolation gown 4 on the transmission belt 103.

[0029] Since the external drive system is existing technology, its structure and operation are not described in detail in this case. The external drive system drives the drive motor 105 and the sliding frame 104 to slide along the slide plate 102 until they move directly above the folded isolation gown 4 on the conveyor belt 103. Then the drive motor 105 drives the pick-up clamp 106 to descend and pick up the folded isolation gown 4. The drive motor 105 and the pick-up clamp 106 are existing mechanical gripping devices. After the pick-up clamp 106 picks up the folded isolation gown 4, the sliding frame 104 continues to slide forward and allows the pick-up clamp 106 and the folded isolation gown 4 to enter the bag support system 2.

[0030] Preferred solutions include Figure 3 and Figure 4As shown, the bag-supporting system 2 includes a lifting platform 201, the lower end of which is connected to a pneumatic lifting rod 202, the other end of which is connected to an external pneumatic system. A side plate 206 is provided on the side of the lifting platform 201, and a strip groove 2061 is formed on the side plate 206. A bag-supporting device 203 is installed in the strip groove 2061. An air-blowing pipe 204 is provided on the conveying platform 101, and the air-blowing pipe 204 is symmetrically installed on the conveying platform 101 via fixing clamps 205. At the end of the air pipe 204, the air outlet is directly facing the bag support system 2; the bag support device 203 includes a mounting plate 2031, a screw 2032 passes through the mounting plate 2031 and the strip groove 2061 and then locks the mounting plate 2031 in place by a fixing nut 2033, a pneumatic rotating rod 2034 is vertically arranged on the upper end face of the mounting plate 2031, one end of the pneumatic rotating rod 2034 is provided with a bag support plate 2035, and the other end of the pneumatic rotating rod 2034 is connected to the spiral air supply pipe 2036;

[0031] When the system is working, the spiral air supply pipe 2036 supplies air through the external pneumatic system and rotates the pneumatic rotating rod 2034. The pneumatic rotating rod 2034 drives the bag support plate 2035 to flip outward, thereby expanding the opening of the packaging bag 5 on the lifting platform 201. At the same time, the air blowing pipe 204 blows air into the packaging bag 5 and causes the packaging bag 5 to expand. The pneumatic lifting rod 202 extends and raises the expanded packaging bag. The sliding frame 104 drives the pickup clamp 106 and the folded isolation gown 4 to smoothly enter the expanded packaging bag 5.

[0032] Preferred solutions include Figure 5 As shown, the sealing subsystem 3 includes a base box 301, a support frame 302 is provided above the base box 301, and a bracket 303 is connected between the support frames 302. A cylinder 304 is vertically mounted on the bracket 303, and the cylinder 304 is vertically connected to the pressure plate 306 below through a rod 305. A sealing machine 307 is installed on the inner side of the support frame 302, and the sealing machine 307 is connected to the heat sealing plate 309 through a telescopic rod 308. An air extraction hole 310 is opened on the upper end face of the base box 301, and a negative pressure fan 311 is installed inside the base box 301.

[0033] When the packaging bag 5 containing the folded isolation gown 4 enters the sealing subsystem 3, the cylinder 304 drives the air rod 305 to extend and the pressure plate 306 to press down the packaging bag 5. At the same time, the negative pressure fan 311 in the base box 301 starts and generates negative pressure inside it, further extracting the air from the packaging bag 5 through the air extraction hole 310. After the packaging bag 5 is compressed, the sealing machine 307 drives the heat sealing plate 309 to descend and seal the opening of the packaging bag 5.
