Description

Technical Field

[0001] This utility model belongs to the field of protective clothing production and processing technology, and in particular relates to a heat sealing device for medical protective clothing. Background Technology

[0002] Medical protective clothing is a type of garment used to protect workers in the healthcare industry. It is designed to isolate pathogens, harmful ultrafine dust, acidic and alkaline solutions, and electromagnetic radiation. It can be categorized into one-piece and two-piece designs based on how it is worn. During the production of medical protective clothing, to ensure its airtightness, users typically use heat-sealing devices to seal the garments. Existing heat-sealing devices, such as the utility model patent (CN216293151U, entitled "A High-Precision Heat-Sealing Device for Medical Protective Clothing Production"), disclose a heat-sealing mechanism, a moving mechanism, a support plate, a pressing plate, and a control panel. However, this existing technology has two limitations: 1. It can only perform linear pressing on the protective clothing, failing to heat-seal areas requiring bending; 2. It is inconvenient to remove and secure the protective clothing. Therefore, the existing technology suffers from low heat-sealing efficiency and cannot heat-seal bent areas of the protective clothing. Utility Model Content

[0003] This invention addresses the technical problems of existing protective clothing, such as the inconvenience of heat sealing bent areas and the difficulty in adjusting the heat-sealed parts. It provides a heat-sealing device for medical protective clothing, comprising a horizontally arranged support plate with several supporting legs at its bottom. A vertically arranged retractable support column is located on the left side of the top of the support plate. The retractable support column includes a vertically arranged outer support tube, the bottom of which is fixed to the top of the support plate. Above the outer support tube is a vertically arranged inner support tube, the lower end of which is slidably fitted onto the upper end of the outer support tube. A vertically arranged electric actuator is positioned between the outer and inner support tubes. The bottom end of the electric actuator is fixed to the outer support tube via a support, and the top end is fixed to the inner support tube via a support. The electric actuator is connected to a power source and a PLC controller via a cable. Activating the electric actuator pushes the inner support tube vertically along the inner wall of the outer support tube, allowing adjustment of the support beam's height. The top of the retractable support column is detachably fixed with a horizontally arranged support beam. The bottom of the support beam is equipped with a left-right displacement mechanism. Below the left-right displacement mechanism is a vertically arranged column. The top of the column is mounted on the left-right displacement mechanism. The left-right displacement mechanism includes a horizontally arranged slide rail, the top of which is fixed to the bottom of the support beam. A slider is slidably connected inside the slide rail. It also includes a lead screw arranged parallel to the slide rail. The two ends of the lead screw are rotatably mounted on the two ends of the slide rail. The slider is threadedly connected to the slide rail. One end of the slide rail is equipped with a lead screw motor, which is connected to the lead screw drive. The lead screw motor is connected to the power supply and PLC controller via a cable. When the lead screw motor is started, it drives the lead screw to rotate and pushes the slider to move freely along the slide rail, thereby adjusting the position of the slider in the left and right directions. A heat-sealing mechanism is fixed at the bottom of the column (the heat-sealing mechanism is existing technology and will not be described in detail here, but is introduced in the background section). A horizontally positioned support platform is provided above the support plate. A rotating mechanism is provided between the support platform and the support plate. The support platform is rotatably mounted on the support plate through the rotating mechanism. The rotating mechanism includes a vertically positioned support shaft, which is rotatably mounted on the support plate through bearings. The top end of the support shaft is fixed to the bottom end of the support platform. A rotary motor bracket is provided at the bottom end of the support plate. A rotary motor is fixed on the rotary motor bracket. The power output shaft of the rotary motor is connected to the support shaft. The rotary motor is connected to the power supply and PLC controller through a cable. When the rotary motor is started, it drives the support platform to rotate through the support shaft, thereby enabling heat sealing of the protective clothing at more angles.The top of the support plate is fixed with an annular guide rail, and the top of the guide rail has an annular guide groove. The bottom of the support platform is provided with several roller brackets arranged circumferentially around the support platform. The lower end of the roller brackets is rotatably equipped with rollers, and the bottom end of the rollers is in roller-pressed fit with the guide rail. The top of the support platform is provided with several clamping mechanisms for holding the protective clothing. Each clamping mechanism is arranged circumferentially around the center line of the support platform. The clamping mechanism includes a vertically arranged upright plate, the bottom end of which is fixed to the top of the support platform. The inner side of the upright plate is provided with an L-shaped pressure plate, the top end of which is hinged to the upper end of the upright plate. An inclined tension spring is provided between the pressure plate and the upright plate. The clamping mechanism facilitates the fixing of the protective clothing to the top of the support platform, making it convenient for the heat sealing mechanism to perform heat sealing treatment on the protective clothing.

[0004] Preferably, the lower end of the support shaft extends downward to form a support plate, and a driven gear is fixed to the lower end of the support shaft. The power output shaft of the rotary motor is fixed with a driving gear, and the driving gear and the driven gear mesh with each other.

[0005] The above scheme has the following advantages: The guide rails and rollers enhance the stability and reduce vibration of the support platform as it rotates, indirectly improving the heat-sealing quality of the protective suit. The rotary mechanism drives the support platform to rotate, facilitating angle adjustment when the heat-sealing parts of the protective suit bend, thus improving heat-sealing efficiency. The clamping mechanism secures the protective suit to be heat-sealed on the support platform, reducing displacement during the heat-sealing process. The left-right displacement mechanism allows for adjustment of the heat-sealing mechanism's position in the left-right direction. Attached Figure Description

Then, the protective suit 9 is pressed and fixed onto the support platform 5 by the pressure plate 82. The electric push rod 23 is activated, which pushes the inner support tube 22 to slide up and down along the inner wall of the outer support tube 21 to adjust the height of the support beam 24. Then, the lead screw motor 34 on the left and right displacement mechanism 3 is activated, which drives the lead screw 33 to rotate. The lead screw 33 pushes the slider 32 to slide along the slide rail 31, thereby adjusting the position of the heat sealing mechanism 4 in the left and right directions. The rotary motor 64 is activated, which drives the support platform 5 and the protective suit 9 at the top of the support platform 5 to rotate a certain angle through the support shaft 61, so that the heat sealing mechanism 4 can heat seal the turning parts of the protective suit 9.
