Description

Technical Field

[0001] This invention relates to the field of surgical gown manufacturing technology, specifically to a folding and welding device for producing surgical gowns. Background Technology

[0002] Surgical gowns, as essential protective clothing during surgery, reduce the risk of medical staff coming into contact with pathogens and also reduce the risk of pathogen transmission between medical staff and patients, serving as a safety barrier in the sterile area during surgical procedures. The waist belt, as an accessory to the surgical gown, is manufactured through processes including inner four-folding, ultrasonic welding, and cutting.

[0003] Utility model patent CN208434766U discloses a nonwoven surgical gown production system. This system uses a cutting roller and a smoothing roller to cut the raw fabric into the desired surgical gown body. A folding plate then bends the gown body at its end, allowing it to fall to a preset length. The folding plate then transfers the gown to a clamping device for folding, ensuring the top and bottom edges of the gown overlap. This method achieves efficient production of surgical gowns and effectively reduces manual labor. However, existing technologies typically use a single welding process for the surgical gowns. This method cannot guarantee the quality of the finished product, resulting in poor quality gowns. Furthermore, the lack of securing the gown during welding can easily cause wrinkles on one side, affecting the welding quality. Summary of the Invention

[0004] The purpose of this invention is to provide a folding and welding device for producing surgical gowns. Two supporting uprights pass through corresponding slots, and the end of a connecting plate is installed to the two supporting uprights. Simultaneously, the top surface of the connecting plate is fixed to the telescopic end of an electric push rod, facilitating the installation of a hot press roller. The electric push rod drives the hot press roller to press against the pre-welded surgical gown. To improve the pressing quality, a guide seat slides on a guide rod and compresses a spring, making the hot press roller press against the surgical gown more tightly and achieving a better heat-sealing effect. Combined with the sliding of a linear guide rail and a slide block, the processing frame moves, thereby achieving a rolling heat-sealing effect on the surgical gown.

A receiving cavity is provided on the top surface of the inner cavity of the folding plate, and a buffer pressure plate for pressing the surgical gowns is installed inside the receiving cavity. A lifting cylinder II for pushing the buffer pressure plate up and down is installed at the top end of the folding plate.

[0012] A further technical improvement of the present invention is that: an L-shaped support is installed on the bottom surface of the processing table near the empty part, and an electric push rod II for pushing the folding plate to rotate is hinged on the bottom surface of the support, and the telescopic end of the electric push rod II is hinged to the bottom surface of the folding plate.

[0013] A further technical improvement of the present invention is that: a sliding cavity is provided inside the processing table and below the linear guide rail, a telescopic plate is slidably installed inside the sliding cavity, a horizontal cylinder for pushing the telescopic plate is installed on the rear surface of the processing table, an electric push rod three is installed on the front top surface of the telescopic plate, and a pressure pad for pressing the surgical gown is fixedly installed at the telescopic end of the electric push rod three.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this invention, the ultrasonic welding head contacts the seam of the surgical gown, thereby welding and sewing the seam of the surgical gown to achieve preliminary welding of the two halves of the surgical gown. Two support plates are passed through the interior of the corresponding through slots, and the end of the connecting plate is installed with the two support plates.

[0026] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0027] Please see Figures 1-6As shown, this invention discloses a folding and welding device for producing surgical gowns, including a processing table 1 for welding and folding surgical gowns. The top surface of the processing table 1 has a processing groove, and a linear guide rail 4 is installed at the end of the top surface of the processing table 1. A slide block 5 is slidably mounted on the linear guide rail 4, and the slide block 5 is fixed to the bottom surface of an L-shaped processing frame 6. A conveyor table 3 is provided on one side of the processing table 1, and a conveyor belt 2 is installed on the top surface of the conveyor table 3, which is in contact with the top surface of the processing groove. An ultrasonic generator 8 for ultrasonic welding is installed on the bottom surface of the processing table 1. A welding protrusion 7 for welding the surgical gown is provided in the middle of the top surface of the processing groove. During welding, the collar of the surgical gown is pre-processed, requiring only the welding of two separate halves of the gown. The welding material for the two halves of the gown is transported to the processing groove by the conveyor belt 2. The welding parts of the two halves of the gown are placed on the welding protrusion 7 for easy welding of the surgical gown material. A laser welding mechanism for welding the surgical gown is provided above the welding protrusion 7. The hot rolling mechanism, laser welding mechanism, and hot rolling mechanism are all installed on the bottom surface of the processing frame 6. The laser welding mechanism includes an ultrasonic welding head 11. A lifting cylinder 10 is also installed on the top surface of the processing frame 6. The piston rod end of the lifting cylinder 10 is fixed to the top surface of the ultrasonic welding head 11. The lifting cylinder 10 pushes the ultrasonic welding head 11 downward, so that the ultrasonic welding head 11 contacts the seam of the surgical gown and welds the seam. In order to ensure the integrity of the seam, the slide 5 slides on the linear guide rail 4, which drives the ultrasonic welding head 11 to move linearly along the welding protrusion 7, thereby welding the seam of the two surgical gowns. The entire operation is completed automatically. The hot rolling mechanism includes a hot pressing roller 18 for hot pressing and sealing the seam of the surgical gown. The length of the hot pressing roller 18 is greater than the bottom diameter of the ultrasonic welding head 11, so that the contact area between the hot pressing roller 18 and the welded and sealed part of the surgical gown is larger, the hot pressing effect is better, the seam quality of the surgical gown is improved, and the product performance is better.

[0028] The hot roller pressing mechanism includes two through slots 17 on the surface of the processing frame 6. Each through slot 17 has a supporting plate 13 slidably mounted inside. A U-shaped connecting plate 16 is mounted on the top inner wall of the two supporting plates 13. An electric push rod 15, fixedly connected to the top surface of the connecting plate 16, is mounted on the top surface of the inner cavity of the U-shaped frame 14. Each supporting plate 13 has a sliding groove 19 on its bottom surface. An I-shaped guide rod 22 is vertically mounted inside the sliding groove 19. A guide seat 20 is slidably mounted on the guide rod 22, and a spring 21 is sleeved on the outside of the guide rod 22 between the sliding groove 19 and the top surface of the guide seat 20. The end of the hot roller 18 is rotatably connected to the side surface of the guide seat 20 via a bearing. When the ultrasonic welding head 11 presses against… After the two surgical gowns are initially welded, the two support plates 13 are passed through the corresponding through slots 17, and the end of the connecting plate 16 is installed with the two support plates 13. At the same time, the top surface of the connecting plate 16 is fixed with the telescopic end of the electric push rod 15. After installation, the two support plates 13 are pushed downward by the electric push rod 15, which drives the hot press roller 18 to press against the initially welded surgical gown. In order to improve the pressing quality, the guide seat 20 slides on the guide rod 22 and squeezes the spring 21, so that the hot press roller 18 presses against the surgical gown more tightly and the heat sealing effect is better. With the sliding of the linear guide rail 4 and the slide seat 5, the processing frame 6 moves, thereby achieving a rolling heat sealing effect on the surgical gown and facilitating the disassembly and assembly of the hot press roller 18.

[0029] A notch 23 is provided on the surface of the processing groove. A folding plate 9 for folding surgical gowns is rotatably mounted inside the notch 23. A receiving cavity 27 is provided on the top surface of the inner cavity of the folding plate 9. A buffer plate 28 for pressing the surgical gown is installed inside the receiving cavity 27. A lifting cylinder 26 for pushing the buffer plate 28 up and down is installed at the top end of the folding plate 9. When one half of the surgical gown reaches one side of the welding boss 7, the lifting cylinder 26 pushes the buffer plate 28 away from the receiving cavity 27, and the buffer plate 28 presses and fixes one half of the surgical gown, ensuring the stability of the surgical gown during welding and preventing damage during the welding process. To improve welding accuracy, an L-shaped support 24 is installed on the bottom surface of the processing table 1 near the missing part 23. An electric push rod 25 for pushing the folding plate 9 to rotate is hinged to the bottom surface of the support 24. The telescopic end of the electric push rod 25 is hinged to the bottom surface of the folding plate 9. After the welding roller pressing is completed, the electric push rod 25 pushes the folding plate 9 to rotate, and the folding plate 9 flips half of the surgical gown, thus achieving the folding effect. During the rotation and folding process, the buffer plate 28 returns to its original position and enters the receiving cavity 27, and the buffer plate 28 loses its restraining effect on half of the surgical gown.

[0030] A sliding cavity 29 is provided inside the processing table 1 and below the linear guide rail 4. A telescopic plate 31 is slidably installed inside the sliding cavity 29. A horizontal cylinder 30 for pushing the telescopic plate 31 is installed on the rear surface of the processing table 1. An electric push rod 32 is installed on the front top surface of the telescopic plate 31. A pressure pad 33 for pressing the surgical gown is fixedly installed at the telescopic end of the electric push rod 32. When welding and rolling the two halves of the surgical gown, the horizontal cylinder 30 pushes the telescopic plate 31 to slide away from the inside of the sliding cavity 29. Then, the electric push rod 32 pushes the pressure pad 33 downward and fits it against the other half of the surgical gown, thus fixing the other half of the surgical gown. In the initial state, the telescopic plate 31 is located inside the sliding cavity 29, while the electric push rod 32 is located on the top front side of the telescopic plate 31. The purpose of this arrangement is not to affect the flipping of the folding plate 9, making it easy to fold the surgical gown after welding and sewing.

[0031] In use, the two support plates 13 are passed through the corresponding through slots 17, and the end of the connecting plate 16 is installed with the two support plates 13. At the same time, the top surface of the connecting plate 16 is fixed with the telescopic end of the electric push rod 15 to facilitate the installation of the hot press roller 18. The electric push rod 15 drives the hot press roller 18 to press against the surgical gown after preliminary welding. In order to improve the pressing quality, the guide seat 20 slides on the guide rod 22 and squeezes the spring 21, so that the hot press roller 18 presses against the surgical gown more tightly and the heat sealing effect is better. With the sliding of the linear guide rail 4 and the slide seat 5, the processing frame 6 moves, thereby achieving a rolling heat sealing effect on the surgical gown. This ensures that the hot press roller 18 contacts the welded sealing part of the surgical gown, resulting in a good heat pressing effect and improving the seam quality of the surgical gown.

[0032] The second lifting cylinder 26 pushes the buffer plate 28 away from the inside of the receiving cavity 27. The buffer plate 28 presses and fixes the half of the surgical gown, ensuring the stability of the surgical gown during welding, avoiding the deviation of the surgical gown during the welding process, and improving the accuracy of welding. The second electric push rod 25 pushes the folding plate 9 to rotate, and the folding plate 9 flips the half of the surgical gown, thereby achieving the effect of folding. During the rotation and folding process, the buffer plate 28 returns to the inside of the receiving cavity 27, and the buffer plate 28 loses its restraining effect on the half of the surgical gown.

[0033] When the two halves of the surgical gown are welded and rolled, the horizontal cylinder 30 pushes the telescopic plate 31 to slide away from the inside of the slide cavity 29. Then, the electric push rod 32 pushes the pressure pad 33 downward and fits it against the other half of the surgical gown, thus fixing the other half of the surgical gown. In the initial state, the telescopic plate 31 is located inside the slide cavity 29, while the electric push rod 32 is located on the top front side of the telescopic plate 31. The purpose of this setting is not to affect the flipping of the folding plate 9, making it easy to fold the surgical gown after welding and sewing.
