[0003] In order to meet the packaging and aesthetic requirements of goods, woven bags will be trimmed at their corners, such as pressing and cutting rounded corners.
[0004] The existing bag corner pressing and cutting device is driven by a driving mechanism to drive the cutter to rise and fall to achieve pressing and cutting. Before pressing and cutting, a limiting mechanism is needed to fix the position of the woven bag to be cut. The angles formed by the limiting mechanism are all right angles.

DETAILED DESCRIPTION
[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0028] like Figure 1-4 As shown, a woven bag corner pressing and cutting device includes a cabinet 1 and a linear drive device 2 located in the cabinet 1. The linear drive device 2 is a cylinder or a hydraulic cylinder. The driving end of the linear drive device 2 passes through the top plate 101 of the cabinet 1 and is connected to a lifting plate 8. A cutter 7 is installed on the lifting plate 8. The cutter 7 is fixed by bolts and can be replaced. Two groups of limit assemblies 5 are also arranged on the top plate 101, and the two groups of limit assemblies 5 are symmetrically arranged with the center line of the cutter 7 as a reference. The limit assembly 5 includes a limit plate 501, which is rotatably connected to the top plate 101. The limit plate 501 is also provided with a locking device 505 for fixing the position of the cutter 7.
[0029] In this embodiment, if Figure 1 and Figure 2 As shown, the limit plates 501 of the two limit assemblies 5 can be rotated, so the angle between the two limit plates 501 can be changed, so that the two limit plates 501 can be rotated according to the corner angles of different types of woven bags, so that the angle formed by the two limit plates 501 corresponds to the corner angle of the woven bag, and then, the two side edges of the corner of the woven bag are respectively attached to the limit plates 501, and then, the linear drive device 2 is controlled to work, driving the cutter 7 to descend, and then the corner of the woven bag is pressed and cut to cut the corner of the woven bag into a desired shape, and a cutting groove 6 is opened on the top of the top plate 101, and the cutting groove 6 is located directly below the cutter 7, so the cutter 7 will not hit the top plate 101 during the pressing and cutting process.
[0030] Among them, Figure 2As shown, the adjacent edges of the two groups of limit assemblies 5 are provided with bar magnets 503, and the limit plates 501 and the top plate 101 are both made of iron. After the position of the limit plates 501 is determined, the two bar magnets 503 can be adsorbed on the adjacent side edges of the two limit plates 501 respectively, and it is ensured that the bar magnets 503 are also adsorbed and fixed to the top plate 101, thereby preventing the edge of the thinner woven bag from being inserted into the gap formed by the limit plates 501 and the top plate 101, and a grip rod 504 is fixedly connected to the top of the bar magnet 503. When the bar magnet 503 needs to be removed, force can be conveniently applied to the bar magnet 503 through the grip rod 504, so that the bar magnet 503 is easy to remove.
[0031] Among them, Figure 1 and Figure 3 As shown, the limit plate 501 is rotatably connected to the top plate 101 via the rotating shaft 502. Therefore, the limit plate 501 rotates around the rotating shaft 502, and the locking device 505 is a locking screw. The limit plate 501 is connected to the locking screw via a threaded through hole. When the position of the limit plate 501 is determined, the locking screw should be tightened so that its bottom is against the top plate 101, thereby fixing the position of the limit plate 501.
[0032] like Figure 1 As shown, the top of the top plate 101 is also connected to the vertical plate 10, the lifting plate 8 is connected to the vertical plate 10 through a sliding device 9, the sliding device 9 includes at least one set of slide rails 901 fixed on the vertical plate 10, and a slider 902 is slidably connected to the slide rails 901. The lifting plate 8 is fixedly connected to the slider 902, and the driving end of the linear drive device 2 is connected to the lifting plate 8 through a connecting device 4;
[0033] like Figure 4 As shown, the connecting device 4 includes a U-shaped plate 402 fixedly connected to the driving end of the linear drive device 2, and a connecting plate 401 is rotatably connected inside the U-shaped plate 402. The connecting plate 401 is fixedly connected to the lifting plate 8, and the slider 902 can only slide on the slide rail 901. The lifting plate 8 is fixedly connected to the slider 902, and the cutter 7 is fixed on the lifting plate 8. Therefore, the sliding device 9 can only make the cutter 7 perform vertical lifting operations, and the linear drive device 2 is connected to the lifting plate 8 through the connecting plate 401 and the U-shaped plate 402. Compared with the method of directly fixing with bolts, in this method, when the lifting plate 8 has unexpected movement (swinging back and forth), the connecting plate 401 can reduce the force transmitted to the linear drive device 2 through its own rotation, thereby minimizing damage to the linear drive device 2.
[0034] Working principle: first, rotate the two limit plates 501 according to the corner angles of different types of woven bags, so that the angle formed by the two limit plates 501 corresponds to the corner angle of the woven bag. Next, tighten the locking screws to make their bottoms against the top plate 101, thereby fixing the position of the limit plates 501, and then adsorb the two bar magnets 503 on the adjacent sides of the two limit plates 501 respectively, and ensure that the bar magnets 503 are also adsorbed and fixed to the top plate 101, so as to avoid the thinner woven bag from being stuck. The edge of the woven bag is inserted into the gap formed by the limiting plate 501 and the top plate 101. In the next step, the two side edges of the corners of the woven bag are respectively attached to the limiting plate 501. Subsequently, the linear drive device 2 is controlled to work, driving the cutter 7 to descend, and then the corners of the woven bag are pressed and cut to cut the corners of the woven bag into the required shape. In addition, a cutting groove 6 is opened on the top of the top plate 101, and the cutting groove 6 is located directly below the cutter 7, so the cutter 7 will not hit the top plate 101 during the pressing and cutting process.
[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
