Description

Technical Field

[0001] This utility model relates to the field of woven bag processing technology, specifically to a woven bag cutting device with a bag pressing structure. Background Technology

[0002] Woven bags are typically made by sewing woven fabric together using a bag-making machine to form a bag tube of a certain length or a sealed bag body. In order to obtain finished bags of specific specifications that facilitate subsequent filling, sealing, or use, it is necessary to cut the continuous bag tube or bag body to a fixed length.

[0003] Traditional woven bag cutting devices typically use a downward-moving cutting blade for cutting. However, during the cutting process, due to the inherent elasticity and flexibility of the woven bag material, it is prone to displacement, wrinkling, or shaking at the moment of cutting. This can lead to deviations in the cutting position or uneven cuts, resulting in a decrease in the quality of the woven bag cutting. Utility Model Content

[0004] (I) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to overcome the defect that the woven bag is prone to displacement during cutting, and to provide a woven bag cutting device with a bag pressing structure.

[0013] (III) Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] The pressure plate and spring in the bag-pressing structure work together to fix the front and back sides of the woven bag during the pressing process of the I-beam frame. At the same time, the vacuum pump actively draws air, creating negative pressure at the pressure plate position. The negative pressure adsorption force makes the woven bag more firmly and evenly pressed, which can effectively prevent the woven bag from shifting or curling during cutting, thus improving the quality of woven bag cutting.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] Combined with appendix Figures 1 to 3 As shown, a woven bag cutting device with a bag-pressing structure includes a workbench 1, a top plate 2 connected to the workbench 1 via a column, a cylinder 3 located at the center of the top plate 2, an I-beam frame 4 connected to the telescopic end of the cylinder 3, a cutter 5 connected to the I-beam frame 4, and fixed plates 6 connected to both sides of the I-beam frame 4. The fixed plates 6 are provided with a bag-pressing structure, which includes a bag-pressing plate 7. Multiple equidistant connecting rods 8 are connected to the bag-pressing plate 7. The fixed plates 6 are provided with through holes 9 adapted to the connecting rods 8. The connecting rods 8 are inserted into the through holes 9. A spring 10 is sleeved on the connecting rods 8. The two ends of the spring 10 abut against the fixed plate 6 and the bag-pressing plate 7, respectively.

[0028] Combined with appendix Figure 3 and Figure 5 As shown, the bottom surface of the bag pressing plate 7 is arrayed with several air holes 11. The bag pressing plate 7 is provided with an air extraction assembly that communicates with the air holes 11. The air extraction assembly includes a vacuum pump 12 fixedly mounted on the side wall of the bag pressing plate 7. The bag pressing plate 7 is provided with an air chamber 13. All air holes 11 are connected to the air chamber 13. The vacuum pump 12 is connected to an air pipe 14. One end of the air pipe 14 passes through the bag pressing plate 7 and communicates with the air chamber 13. The bottom surface of the bag pressing plate 7 is provided with a sponge gasket 15 around the side of the bag pressing plate 7. The gasket 15 can fill the gap between the edge of the bag pressing plate 7 and the workbench 1 or the woven bag, effectively preventing gas leakage.

[0029] Among them, the combination of appendix Figure 2 and Figure 3As shown, the I-beam frame 4 has limiting holes 22 at its four corners that match the columns. The columns are inserted into the limiting holes 22. The limiting holes 22 restrict the trajectory of the I-beam frame 4 as it rises and falls, serving as a guide to ensure the stability of its rise and fall and to prevent deviation and swaying.

[0030] The woven bag is conveyed to the predetermined cutting position on the workbench 1. The cylinder 3 drives the I-beam frame 4 to descend. At the same time, the bag-pressing plates 7 on both sides of the I-beam frame 4 also descend. When the bag-pressing plates 7 contact the woven bag, the vacuum pump 12 starts and presses the bag-pressing plates 7 into a negative pressure state through the air hole 11, thereby firmly fixing the woven bag. As the cutter 5 continues to descend, the front and back sides of the woven bag are firmly and evenly fixed with the cooperation of the spring 10 and the bag-pressing plates 7 until the cutting is completed. After completion, the cylinder 3 lifts the I-beam frame 4, the vacuum pump 12 releases the air, and the woven bag is adsorbed.

[0031] To further improve cutting efficiency and quality, and reduce unevenness of the cut, combined with the attached... Figure 3 , Figure 4 and Figure 6 As shown, the bottom surface of the I-beam frame 4 is provided with a mounting part 16, and a connecting groove 17 is provided on the mounting part 16. The top of the cutter 5 is connected to a connecting part 18 that is adapted to the connecting groove 17. The connecting part 18 is fixedly connected to the mounting part 16 by multiple bolts. The workbench 1 is provided with a blade groove 19 directly below the cutter 5. The blade groove 19 cooperates with the cutter 5 to provide space for the cutter 5 to fall, so as to better cut woven bags. The bottom surface of the mounting part 16 is provided with electric heating plates 20 on both sides of the connecting groove 17. The mounting part 16 is provided with a U-shaped heat insulation cover 21 outside the electric heating plate 20. The heat insulation cover 21 can prevent workers from accidentally touching high-temperature parts and getting burned.

[0032] The bolt-connected cutter 5 facilitates the repair and replacement of worn cutter 5. The electric heating plate 20 located on both sides of the cutter 5 can heat the cutter 5. The hot cutting method for cutting woven bags can prevent rough edges and loose edges, thus improving the cutting quality.

[0033] The present invention and its embodiments have been described above.
