[0002] Plastic bag manufacturing is an important part of the plastics processing industry, and its production process involves multiple steps and key technologies.

[0003] The main raw material for plastic bags is plastic particles such as polyethylene or polypropylene. These plastic particles are usually obtained through petrochemical processing and have characteristics such as high strength and impact resistance. Before bag making, these plastic particles need to be processed into granular materials by a crusher for subsequent melting and extrusion. After that, the crushed plastic particles are poured into a storage bin for storage and use. However, the existing storage bin devices do not have the function of adjusting the size of the plastic particles during feeding. Therefore, the quantity of plastic particles fed during the feeding process cannot be accurately controlled, which will adversely affect subsequent melting, extrusion, and blown film steps.

[0004] Therefore, we propose a novel adjustable-size plastic bag maker. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figure 1-2 This utility model provides a technical solution: an adjustable-size plastic bag maker, including a bag maker body 1, a storage box 2 at the top of the bag maker body 1, and a feeding adjustment component 3 connected to the bottom of the storage box 2. The feeding adjustment component 3 includes an adjustment box 301, a sliding groove 302 inside the adjustment box 301, an adjustment plate 304 inside the sliding groove 302, a feeding hole 303 through the side of the adjustment box 301, a threaded hole 305 inside the adjustment plate 304, a servo motor 306 connected to the outer surface of one side of the adjustment box 301, a one-way screw 307 connected to the output end of the servo motor 306, a bearing sleeve 308 on the surface of the one-way screw 307 near the servo motor 306, and a PLC control panel 309 connected to the front surface of the storage box 2.

[0025] like Figure 2 As shown, the servo motor 306 and the PLC control panel 309 are electrically connected. The PLC control panel 309 is electrically connected to an external power supply through a control switch. The servo motor 306 can be started through the PLC control panel 309, which facilitates the adjustment of the feeding speed.

[0026] like Figure 2 As shown, the one-way screw 307 is threadedly connected to the adjusting plate 304 through the threaded hole 305, and the bearing sleeve 308 is rotatably connected to the one-way screw 307. The position of the adjusting plate 304 can be adjusted by rotating the thread, thereby achieving the purpose of adjusting the feeding quantity control. The bearing sleeve 308 can improve the stability of the one-way screw 307 when rotating.

[0027] As shown in Figure 2, the outer surface of the adjusting plate 304 is in contact with the inner wall of the slide groove 302. The adjusting plate 304 is connected to the adjusting box 301 through the slide groove 302, which facilitates the movement of the adjusting plate 304 within the slide groove 302.

[0028] like Figure 1 and Figure 3 As shown, a cleaning component 4 is provided on the top of the storage bin 2. The cleaning component 4 includes a stirring motor 401, which is connected to the center of the top of the storage bin 2. The stirring motor 401 can fully stir the plastic particles in the storage bin 2, so that the raw materials are more evenly distributed and avoid local accumulation or emptying.

[0029] like Figure 3 As shown, the top two sides of the storage box 2 are provided with inlets 402, and the output end of the stirring motor 401 is connected to the stirring rod 403. The stirring rod 403 has slots 405 on both sides. The inlets 402 can easily pour the raw materials into the storage box 2.

[0030] like Figure 3 As shown, each set of slots 405 is equipped with a spring 406 inside. A push rod 407 is connected to one side of the spring 406, and a scraper 404 is connected to one side of the push rod 407. The scraper 404 can easily clean the raw materials adsorbed on the inner wall of the storage box 2, ensuring the cleanliness of the inside of the storage box 2.

[0031] like Figure 3 and Figure 4 As shown, the outer surface of the scraper 404 is in contact with the inner wall of the storage bin 2, and the push rod 407 and the spring 406 form an elastic structure. The spring 406 will push the scraper 404 tightly against the inner wall of the storage bin 2 through its own elastic force, thereby improving the cleaning effect.

[0032] The operating method and working principle of this device are as follows: When producing plastic bags through the bag maker body 1, plastic granules can be poured into the storage bin 2. When it is necessary to increase the size of the feeding hole 303, the reverse rotation function of the servo motor 306 can be activated through the PLC control panel 309, so that the servo motor 306 can drive the one-way screw 307 to rotate in the reverse direction. The bearing sleeve 308 can improve the stability of the one-way screw 307 during rotation. While the one-way screw 307 rotates in the reverse direction, it will also rotate in the opposite direction through the threaded hole 305 and the adjusting plate 304, so that the adjusting plate 304 can slide in the slide groove 302, thereby opening the feeding hole 303. After adjusting to a suitable feeding speed, the servo motor 306 can be turned off. When it is necessary to close the feeding hole 303, it can be done through the PLC control panel 309. The forward rotation of the one-way screw 307 is initiated, causing the one-way screw 307 to rotate in the forward thread through the threaded hole 305 and the adjusting plate 304. This allows the adjusting plate 304 to move towards the feed inlet 402, thus closing the feed inlet 402 and achieving precise control of the raw material feeding quantity. This avoids the problem that the quantity of plastic granules fed cannot be accurately controlled, which would adversely affect subsequent melting, extrusion, and blown film steps. After the plastic granule raw material is poured into the storage box 2 through the feed inlet 402, the stirring motor 401 can be started to drive the stirring rod 403 to stir and mix the raw material. At the same time, the spring 406 will also push the push rod 407 through its own elasticity, causing the scraper 404 to stick tightly to the surface of the adjusting box 301. While mixing, the scraper 404 can also clean the inner wall of the storage box 2.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
