Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] The following gives specific embodiments.

[0035] Please refer to Figure 1 , the present utility model provides a feeding mechanism for a plastic bag sealing, bag making and slitting machine, including two support plates 1 and two support mechanisms 2 respectively located at the front parts of the mutually remote sides of the two support plates 1;

[0036] A first stabilizing plate 3 is fixedly connected to the lower front side between the two support plates 1. Two telescopic cylinders 4 are fixedly connected to the upper end of the first stabilizing plate 3. A support plate 5 is fixedly connected to the upper ends of the two telescopic cylinders 4. A second stabilizing plate 6 is fixedly connected to the lower rear side between the two support plates 1. A guiding roller 7 is movably connected to the upper rear part between the two support plates 1.

[0037] Further, as Figure 2 shown, the support mechanism 2 includes a fixing plate 21. A first sliding groove 22 is formed in the middle of the upper end of the fixing plate 21. A moving groove 23 is formed in the front wall of the first sliding groove 22. A fixing seat 24 is slidably connected inside the first sliding groove 22. A moving hole 241 is formed in the upper part of the left end of the fixing seat 24. A threaded hole 242 is formed in the lower part of the front end of the fixing seat 24. A support assembly 25 is movably connected inside the moving hole 241. A fastening bolt 26 is threadedly connected inside the threaded hole 242. A fastening plate 27 is fixedly connected to the front part of the outer surface of the fastening bolt 26. The fixing plate 21 is fixedly connected to the support plate 1. The fastening bolt 26 is located inside the moving groove 23.

[0038] Through the above solution: When the support mechanism 2 is in use, after the support assembly 25 is connected to the inner cylinder of the raw material roll, the fastening bolt 26 can be tightened to make the fastening plate 27 outside the fastening bolt 26 and the fixing plate 21 frictionally limit each other, so as to realize the limiting and fixing of the fixing seat 24 and the support assembly 25 and prevent the raw material roll from falling off during the use of the device.

[0039] Further, as Figures 3 - 5As shown in the figure, the support assembly 25 includes a fixed rod 251. One end of the fixed rod 251 is fixedly connected to a grip rod 252. In the middle of the outer surface of the fixed rod 251, a threaded ridge 253 is fixedly connected. On the side of the outer surface of the fixed rod 251 away from the grip rod 252, four second sliding grooves 254 are provided at equal distances in a circular array. Springs 255 are arranged inside the four second sliding grooves 254 and support members 256 are slidably connected to them respectively. The outer surface of the fixed rod 251 is threadedly connected with an adjusting ring 257 through the threaded ridge 253. One end of the adjusting ring 257 away from the grip rod 252 is fixedly connected to a top ring 258. The fixed rod 251 is inserted and movably connected with the moving hole 241. The grip rod 252 is located on the side of the fixed seat 24 away from the support plate 1, and the adjusting ring 257 is located on the side of the fixed seat 24 close to the support plate 1. The four support members 256 are all located on the side of the adjusting ring 257 away from the fixed seat 24. The four springs 255 are respectively located on the side of the four support members 256 away from the adjusting ring 257. The four second sliding grooves 254 are all inclined. The support member 256 includes a support plate 2561. One end of the support plate 2561 close to the fixed rod 251 is fixedly connected to a connecting block 2562 and a reinforcing block 2563. One end of the connecting block 2562 close to the fixed rod 251 is fixedly connected to a slider 2564. The reinforcing block 2563 is located on the side of the connecting block 2562 away from the adjusting ring 257 and is fixedly connected to the connecting block 2562. The slider 2564 is located inside the second sliding groove 254, and both the slider 2564 and the connecting block 2562 are slidably connected to the second sliding groove 254.

[0040] Through the above solution: the four support members 256 in the support assembly 25 can be moved and expanded through the adjustment of the adjusting ring 257, so as to support and fix the inner cylinder of the raw material roll with deformation and the inner cylinders of raw material rolls of different specifications, which can greatly improve the practicability of the device.

[0041] Working principle: The present utility model provides a feeding mechanism for a plastic bag sealing, bag making and slitting machine. The core highlight lies in its unique support mechanism 2 design. This mechanism is internally provided with a flexible support assembly 25, which is particularly equipped with four adjustable and automatically expandable support members 256. In actual operation, the user first adjusts the position of the fixed seat 24 to accurately insert the inner cylinder of the raw material roll between the support assemblies 25 in the two support mechanisms 2. Subsequently, by rotating the adjusting ring 257, the four support members 256 are driven to slowly move along a preset track towards the center of the raw material roll and automatically expand outwards during this process until they closely fit and stably support the raw material roll.

[0042] The ingenuity of this design lies in its high adaptability and flexibility. Whether facing the slightly deformed inner cylinder of the raw material roll due to long-term storage or raw material rolls of different specifications and models, through the flexible adjustment and expansion of the support member 256, this mechanism can provide stable and reliable support, greatly broadening the application range of the equipment and significantly enhancing its practical value.

[0043] In addition, to further optimize the user experience, a spring 255 element is cleverly incorporated into the sliding path of the support member 256 - the second chute 254. This design enables, when it is necessary to replace the raw material roll, the user to simply rotate the adjustment ring 257 in the reverse direction, and the support member 256 can automatically retract to its initial position with the assistance of the elastic force of the spring 255, thus easily achieving the rapid separation of the support assembly 25 from the inner cylinder of the raw material roll, greatly simplifying the replacement process and improving work efficiency.

[0044] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
