Description

Technical Field

[0001] This utility model relates to the field of woven bag cutting technology, and in particular to a positioning and cutting device for woven bag production. Background Technology

[0002] Woven bags are a type of plastic packaging product. Due to their low cost, long service life, and recyclability, they are widely used for packaging various items. Currently, in the production process of woven bags, a positioning and cutting device is usually required to cut the woven bags.

[0003] Existing positioning and cutting equipment typically uses a hot cutting blade to cut woven bags. However, during the hot cutting process, the cut edge of the woven bag is not positioned, which can easily cause the cut edge to move during cutting, affecting the cutting quality. At the same time, the part of the woven bag cut by the hot cutting blade at high temperature will generate molten waste that adheres to the hot cutting blade, thus affecting the smoothness of the entire cutting operation. Therefore, to solve these problems, designing a positioning and cutting device for woven bag production is something we need to consider. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a positioning and cutting device for woven bag production. This device incorporates a positioning and cutting mechanism to locate the cutting point of the woven bag and facilitate subsequent hot cutting operations, ensuring the cutting quality of the woven bag. It also includes a cleaning mechanism to scrape off and recycle molten waste from the hot cutting blade, ensuring smooth operation and improving work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning and cutting device for woven bag production includes a workbench with a U-shaped support frame fixedly connected to its upper end; a positioning and cutting mechanism including two telescopic rods installed on the upper end of the U-shaped support frame, the telescopic ends of the two telescopic rods being fixedly connected to a fixed plate, a hot cutting blade installed at the lower end of the fixed plate, a U-shaped limiting plate provided below the fixed plate, two guide rods fixedly connected to the upper end of the U-shaped limiting plate, the upper ends of the two guide rods penetrating the fixed plate and fixedly connected to a limiting block, two rectangular inner grooves formed at the upper end of the workbench, and an electromagnet installed in each of the two rectangular inner grooves; and a cleaning mechanism for cleaning the hot cutting blade.

[0007] Preferably, both guide rods are slidably connected to the fixed plate, and both electromagnets are engaged with the U-shaped limiting plate.

[0008] Preferably, the cleaning mechanism includes two scrapers fixedly connected to the inner sides of the front and rear of the U-shaped limiting plate, a cleaning block fixedly connected to the lower end of the workbench, a cleaning cavity opened in the cleaning block, a cleaning port opened at the top of the cleaning cavity, a vacuum cleaner installed at the lower end of the workbench, and the suction end of the vacuum cleaner is connected to the cleaning cavity through a conveying pipe.

[0009] Preferably, both scrapers are engaged with a hot cutting blade, a hot cutting groove is provided at the upper end of the worktable, and two U-shaped support legs are fixedly connected to the lower end of the worktable.

[0010] Preferably, the hot cutting groove is located directly above the cleaning port and directly below the hot cutting blade.

[0011] Preferably, both telescopic rods are electrically operated telescopic rods.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] A positioning and cutting mechanism is installed. By controlling two telescopic rods, the hot cutting blade and the return-shaped limiting plate can be moved down synchronously to complete the hot cutting operation. During this process, the return-shaped limiting plate, together with two electromagnets, can position the woven bag at the cutting point, preventing the woven bag from shifting during hot cutting and ensuring the actual cutting quality. A cleaning mechanism is also installed. Two scrapers can scrape off the molten waste adhering to the hot cutting blade. With the help of a vacuum cleaner, the scraped molten waste can be cleaned and recycled in a unified manner, effectively ensuring the smoothness of the cutting operation and improving the overall work efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A positioning and cutting device for woven bag production includes a workbench 1. A U-shaped support frame 2 is fixedly connected to the upper end of the workbench 1. A hot cutting groove 15 is opened at the upper end of the workbench 1. The hot cutting groove 15 is located directly above the cleaning port 12 and directly below the hot cutting blade 5. The hot cutting groove 15 allows the hot cutting blade 5 to pass through and allows the molten waste scraped off later to pass through. Two U-shaped support legs 16 are fixedly connected to the lower end of the workbench 1.

[0021] The system also includes a positioning and cutting mechanism, which consists of two telescopic rods 3 mounted on the upper end of the U-shaped support frame 2. Both telescopic rods 3 are electric telescopic rods, and the telescopic ends of the two telescopic rods 3 are fixedly connected to a fixed plate 4. A hot cutting knife 5 is installed at the lower end of the fixed plate 4, and a loop-shaped limiting plate 6 is set below the fixed plate 4. Two guide rods 7 are fixedly connected to the upper end of the loop-shaped limiting plate 6. The upper ends of the two guide rods 7 pass through the fixed plate 4 and are fixedly connected to a limiting block 8. The two limiting blocks 8 can ensure that the loop-shaped limiting plate 6 and the fixed plate 4 move upward synchronously after the hot cutting is completed. The two guide rods 7 are slidably connected to the fixed plate 4. Two rectangular inner grooves are opened at the upper end of the worktable 1. Electromagnets 9 are set in the two rectangular inner grooves. The two electromagnets 9 cooperate with the loop-shaped limiting plate 6. The part of the loop-shaped limiting plate 6 that contacts the two electromagnets 9 at the lower end is made of iron. When the two electromagnets 9 are activated, they can magnetically attract the loop-shaped limiting plate 6, thereby achieving stable positioning of the woven bag.

[0022] The system also includes a cleaning mechanism for cleaning the hot cutting blade 5. The cleaning mechanism includes two scraper blades 10 fixedly connected to the inner sides of the front and rear of the U-shaped limiting plate 6. Both scraper blades 10 cooperate with the hot cutting blade 5 and can scrape off the molten waste adhering to the hot cutting blade 5. A cleaning block 11 is fixedly connected to the lower end of the workbench 1. A cleaning chamber is opened in the cleaning block 11. A cleaning port 12 is opened at the top of the cleaning chamber. A vacuum cleaner 13 is installed at the lower end of the workbench 1. The vacuum cleaner 13 is existing technology and mainly consists of a motor, fan, suction port, filter, dust collection box, etc. The suction end of the vacuum cleaner 13 is connected to the cleaning chamber through a conveying pipe 14.

[0023] In this utility model, during use, the woven bag to be cut is transported to the upper end of the workbench 1, and the cut of the woven bag is ensured to be located at the hot cutting groove 15. Then, the hot cutting knife 5 is started and the two telescopic rods 3 are controlled to drive the fixed plate 4 to move down, which in turn drives the hot cutting knife 5 and the loop-shaped limiting plate 6 to move down synchronously. During the downward movement, the lower end of the loop-shaped limiting plate 6 will first abut against the woven bag and stop moving down. At this time, the two electromagnets 9 are started, so that the two electromagnets 9 respectively magnetically attract the lower two sides of the loop-shaped limiting plate 6. In this way, the cutting point of the woven bag can be positioned, and the woven bag will not be displaced during subsequent hot cutting, which will affect the cutting quality.

[0024] After positioning, the fixed plate 4 continues to move downwards, driving the hot cutting blade 5 to perform hot cutting on the woven bag. After hot cutting, the operator can control the two telescopic rods 3 to move the fixed plate 4 and the hot cutting blade 5 upwards simultaneously. During the upward movement, the hot cutting blade 5 will continuously contact the two scraper strips 10. The two scraper strips 10 can scrape off the molten waste adhering to the hot cutting blade 5. During this period, the vacuum cleaner 13 is activated, and the scraped molten waste can be passed through the hot cutting channel 15, the cleaning port 12, the conveying pipe 14, and finally cleaned and recycled into the vacuum cleaner 13. After the hot cutting blade 5 is completely separated from the two scraper strips 10, the two electromagnets 9 are turned off to cancel the adsorption limit of the loop-shaped limiting plate 6. Subsequently, the fixed plate 4 can drive the hot cutting blade 5 and the loop-shaped limiting plate 6 to move upwards simultaneously to the initial position. The whole process is convenient and quick. After hot cutting is completed, the molten waste on the hot cutting blade 5 can be scraped off and recycled in a unified manner, which improves the overall work efficiency.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
