Description

Technical Field

[0001] This utility model relates to the field of plastic bag conveying technology, and more specifically, to a conveying device for a plastic bag production line. Background Technology

[0002] Plastic bags, as an important packaging material, are widely used in food, daily necessities, chemical products, and other fields. With the continuous growth in demand for plastic bags, production technology is also constantly being updated and developed. In the plastic bag production process, the conveying device, as one of the key pieces of equipment, plays a crucial role. Its main function is to effectively transport different materials or products in various production processes to ensure the efficient operation of the production line. For example, in the early stage of production, plastic granules are sent from the raw material storage area to the extruder through the conveying equipment. During the blown film process, the extruded plastic film needs to flow through the conveying device for further processing. During the bag making process, the completed plastic film or printed film needs to be transported to the next process through the conveying device to ensure a smooth production flow. The finished bag products need to be sent to the packaging area through the conveying device for subsequent packaging and storage.

[0003] Existing plastic bag production lines use conveyor systems that make it difficult to adjust the tension of plastic bags when sending them to the winding and packaging area, thus affecting the winding quality of the plastic bags. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the above-mentioned traditional technology and provide a conveying device for a plastic bag production line that overcomes or at least partially solves the above-mentioned technical problems.

[0005] The objective of this utility model is achieved through the following technical measures:

[0012] In a preferred embodiment, a drive ring is slidably sleeved on the surface of the take-up roller, and the drive ring is fixedly connected to the take-up rod for driving the take-up rod to retract.

[0017] The present invention provides a conveying device for a plastic bag production line, the advantages of which include:

The first electric telescopic rod then resets, driving the winding rod to retract into the winding roller. The plastic bag roll then falls onto the surface of the unloading hopper for unloading. Simultaneously, another set of winding reels is activated to wind the plastic bag, improving winding efficiency. By setting up a tensioning mechanism, during the initial winding of the plastic bag by the winding reel and winding rod, the second electric telescopic rod drives a toothed plate to extend, driving the mounting frame to move the tensioning roller upwards, reducing tension and ensuring proper winding of the plastic bag. As the thickness of the wound plastic bag gradually increases, the second electric telescopic rod drives the tensioning roller to gradually move downwards, increasing tension and ensuring winding quality.

[0027] Reference Figures 1 to 4 In a preferred embodiment, a drive ring 310 is slidably sleeved on the surface of the take-up roller 303. The drive ring 310 is fixedly connected to the take-up rod 305 and is used to drive the take-up rod 305 to retract. A first electric telescopic rod 311 is fixedly installed on the side wall of the turntable 301. A drive frame 312 is fixedly installed on the telescopic end of the first electric telescopic rod 311. The drive frame 312 is sleeved on the surface of the drive ring 310. A feeding bin 313 is fixedly installed in the inner cavity of the frame 1 for feeding plastic bag rolls. The first electric telescopic rod 311 can drive the drive frame 312 to drive the drive ring 310 and the take-up rod 305 to move towards the take-up reel 304, thereby limiting the plastic bag in the take-up reel 304. Then, the second motor 309 drives the take-up reel 304 to rotate, so as to rewind the plastic bag.

[0028] In a preferred embodiment, during use, the first electric telescopic rod 311 drives the drive frame 312 to move the drive ring 310 and the winding rod 305 toward the winding reel 304, and one end of the plastic bag passes through the bottom of the winding rod 305 and rests on the surface of the first guide roller 302, thereby limiting the plastic bag in the winding reel 304 by the winding rod 305. Then, the second motor 309 drives the winding reel 304 to rotate, so as to wind up the plastic bag. At the same time, the first motor 307 drives the turntable 301 to rotate 180 degrees clockwise until the winding is completed. Then, the first electric telescopic rod 311 resets, and the winding rod 305 is driven to retract into the winding roller 303. The plastic bag roll can then fall onto the surface of the unloading bin 313 for unloading. Simultaneously, another set of winding reels 304 is turned on to wind up the plastic bag, improving the winding efficiency.

[0029] Reference Figures 1 to 5 In a preferred embodiment, a tensioning mechanism 4 is mounted on the surface of the conveyor frame 2 for tensioning the plastic bag. The tensioning mechanism 4 includes a second guide roller 401 and a tensioning roller 404. The second guide roller 401 is rotatably mounted in the inner cavity of the conveyor frame 2. A rotating shaft 402 is rotatably mounted in the inner cavity of the conveyor frame 2. A mounting frame 403 is fixedly mounted on the surface of the rotating shaft 402. A tensioning roller 404 is rotatably mounted in the inner cavity of the mounting frame 403 for tensioning the plastic bag and improving the winding quality.

[0030] Reference Figures 1 to 5 In a preferred embodiment, a second gear 405 is fixedly mounted on the surface of the rotating shaft 402, a toothed plate 406 is slidably mounted on the side wall of the conveyor frame 2, the toothed plate 406 meshes with the second gear 405, and a second electric telescopic rod 407 is fixedly mounted on the side wall of the conveyor frame 2, the telescopic end of the second electric telescopic rod 407 being fixedly connected to the toothed plate 406.

[0031] In a preferred embodiment, when the plastic bag is initially wound up by the take-up reel 304 and the take-up rod 305, the toothed plate 406 is extended by the second electric telescopic rod 407, which drives the mounting bracket 403 to move the tension roller 404 upward, reducing the tension force and ensuring that the take-up rod 305 can properly wind up the plastic bag. As the thickness of the wound plastic bag gradually increases, the tension roller 404 is gradually moved downward by the second electric telescopic rod 407, at which point the tension force increases, ensuring the winding quality.

[0032] Working principle: In use, the first electric telescopic rod 311 drives the drive frame 312 to move the drive ring 310 and the winding rod 305 towards the winding reel 304, so that one end of the plastic bag passes through the bottom of the winding rod 305 and rests on the surface of the first guide roller 302. Thus, the winding rod 305 limits the plastic bag in the winding reel 304. Then, the second motor 309 drives the winding reel 304 to rotate, so as to wind up the plastic bag. At the same time, the first motor 307 drives the turntable 301 to rotate 180 degrees clockwise until the winding is completed. Then, the first electric telescopic rod 311 resets, and the winding rod 305 is driven to retract into the winding roller 303. The plastic bag roll can then fall onto the surface of the unloading bin 313 for unloading. Simultaneously, another set of winding reels 304 is opened to wind up the plastic bag, improving the winding efficiency.

[0033] When the plastic bag is initially wound up by the take-up reel 304 and take-up rod 305, the toothed plate 406 is extended by the second electric telescopic rod 407, which drives the mounting bracket 403 to move the tension roller 404 upward, reducing the tension and ensuring that the take-up rod 305 can properly wind up the plastic bag. As the thickness of the plastic bag gradually increases, the tension roller 404 is gradually moved downward by the second electric telescopic rod 407, at which point the tension increases to ensure the winding quality.
