[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figure 1 、 Figure 2 and Figure 4 The utility model provides an embodiment: a non-PVC film weak welding mold welding device, including a body 1, a pressing mechanism 18 is installed in the middle of the body 1, a weak welding mold 5 is installed at the bottom of the pressing mechanism 18, the front and rear sides of the bottom of the weak welding mold 5 are slidably connected with a rectangular protrusion 8, the right side of the bottom of the weak welding mold 5 is fixedly connected with a fixed long plate 19, the front and rear sides of the fixed long plate 19 are penetrated by the rectangular protrusion 8, and the local pressure is increased by the installation of the rectangular protrusion 8. The right side of the rectangular protrusion 8 is fixedly connected with a connecting short column 7, and a sliding groove 20 is provided on the right side of the weak welding mold 5. The sliding groove 20 is internally slidable. It is connected to a sliding column 23, and the right side of the sliding column 23 is fixedly connected to a moving circular plate 21. The front and rear sides of the sliding column 23 are fixedly connected to a connecting rod 6. The bottom end of the connecting rod 6 is fixedly connected to the connecting short column 7. A panel 15 is installed at the middle and lower part of the body 1. A fixing mechanism 2 is installed on the top of the panel 15. The fixing mechanism 2 is used to fix the medicine bag. The right side of the moving circular plate 21 is fixedly connected to a connecting column 22. The right side of the connecting column 22 is rotatably connected to a turntable 24. The installation of the turntable 24 facilitates the movement of the sliding column 23. The front and rear ends of the right side of the body 1 are fixedly connected to a fixed square plate 10. The middle part of the fixed square plate 10 is rotatably connected to a rotating column 9.
[0033] Specifically, first, a sliding groove 20 is opened on the right side of the weak welding mold 5. By holding the turntable 24 and moving it up and down, the turntable 24 will make the movable circular plate 21 slide up and down with the sliding column 23 inside the sliding groove 20 through the connecting column 22. Since the two sides of the sliding column 23 are fixedly connected to the rectangular protrusions 8 on the front and rear sides through the connecting rod 6, the rectangular protrusions 8 on both sides slide on the outer wall of the fixed long plate 19. Through the installation of the rectangular protrusions 8 on both sides, the local pressure is increased during the welding process, thereby achieving the effect of blocking the small holes passing through the junction of the virtual weld and the real weld. The movement of the sliding column 23 changes the position of the rectangular protrusions 8 on both sides, so that the device is also applicable when facing non-PVC films of different sizes, thereby expanding the scope of application and improving production efficiency. After the weak welding is completed, it is accurately transported to the next stage through the rotating column 9.
[0034] Reference Figure 1 、 Figure 3 and Figure 5 The fixing mechanism 2 includes a plurality of fixing plates 201, and the plurality of fixing plates 201 are equidistantly installed on the top of the panel 15. The front side of the top of the fixing plate 201 is fixedly connected to a fixing block 207. Through the installation of the fixing plate 201, the non-PVC film can be pressed. The front side of the fixing plate 201 is rotatably connected to a rotating short column 206, and the front side of the rotating short column 206 is rotatably connected to a right-angle plate 203. The front side of the right-angle plate 203 is slidably connected to a connecting long rod 202. The top of the connecting long rod 202 is fixedly connected to the fixing block 207 through a connecting soft rod 205. The bottom front sides of the right-angle plates 203 on both sides are fixedly connected to a limiting block 204 to prevent excessive movement during movement. The middle part of the front side of the connecting long rod 202 is fixedly connected to the second handle 16. The middle part of the second handle 16 is installed with a protective cover 17. The installation of the second handle 16 facilitates the movement of the connecting long rod 202.
[0035] Specifically, before the non-PVC film is spread flat on the panel 15, the second handle 16 is moved downward to move the connecting long rod 202 downward. Since the connecting long rod 202 is fixedly connected to the rotating short column 206 through the connecting soft rod 205, this will cause the three fixed plates 201 to tilt upward. Then, it is spread flat on the panel 15, and the second handle 16 is moved upward. The connecting long rod 202 moves upward accordingly, causing the fixed plates 201 to return to their original position and press the non-PVC film. This process can avoid the position of the non-PVC film from moving during the weak welding process, thereby preventing the weak welding from failing and effectively reducing the failure rate. The installation of the protective cover 17 can avoid it from slipping out of your hand when using the second handle 16.
[0036] Reference Figure 1 、 Figure 2 and Figure 3 The left and right ends of the bottom front side of the body 1 are both equipped with cabinet doors 12, and the front side of the cabinet door 12 is fixedly connected to the first handle 14. The bottom of the body 1 is fixedly connected to the base 11, and the left and right ends of the middle part of the base 11 are both provided with forklift holes 13. The top right side of the body 1 is fixedly connected to the slide box 3, and the interior of the slide box 3 is equidistantly slidably connected to a plurality of hooks 4;
[0037] Specifically, the cabinet doors 12 on both sides can be opened through the first handle 14, and the equipment inside can be inspected. During work, the staff can hang some items on the hook 4 for easy removal and use. The forklift hole 13 is opened to facilitate the movement of the device.
[0038] Working principle: First, a sliding groove 20 is opened on the right side of the weak welding mold 5. By holding the turntable 24 and moving it up and down, it slides up and down inside the sliding groove 20. Since the two sides of the sliding column 23 are fixedly connected to the rectangular protrusions 8 on the front and rear sides through the connecting rods 6, the rectangular protrusions 8 on both sides slide on the outer wall of the fixed long plate 19. The installation of the rectangular protrusions 8 on both sides increases the local pressure, which can achieve the effect of blocking the through-holes at the intersection of the virtual welding and the stone welding. By moving the positions of the rectangular protrusions 8 on both sides, it can be applied to non-PVC films of different sizes, thereby increasing the scope of application and improving production efficiency.
[0039] Before the non-PVC film is laid flat on the panel 15, the second handle 16 is moved downward, so that the connecting long rod 202 moves downward. Since the connecting long rod 202 is fixedly connected to the rotating short column 206 through the connecting soft rod 205, the three fixed plates 201 are tilted upward. Then it is laid flat on the panel 15, and the second handle 16 is moved upward. The connecting long rod 202 will move upward accordingly, and the fixed plates 201 will return to their original position and press the non-PVC film. This can avoid the position of the non-PVC film from moving during the weak welding process, which may cause the weak welding to fail, thereby reducing the failure rate.
[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
