Description

Technical Field

[0001] This application relates to the field of finished cotton bag opening technology in textile production, and in particular to an auxiliary device for opening finished cotton bags. Background Technology

[0002] Finished cotton is the basic raw material for textile production, and its use involves multiple stages such as opening, carding, spinning, and weaving. By breaking down cotton clumps into single fibers, and then forming yarn through processes such as combing and spinning, the yarn can be used in textile production.

[0003] Currently, textile companies typically purchase packaged cotton in bags. Cotton expands during transport, so to reduce its volume and increase transport capacity, each cotton bag is usually secured with multiple reinforcing ribs (such as wire) to compress the cotton inside and reduce its volume. Once the cotton bags are delivered to the textile company, these ribs need to be cut to open the bags and remove the cotton.

[0004] like Figure 1 As shown, currently, mechanical cutting of the stirrups is done using wire cutters. However, because the stirrups are compressed and bound to the cotton bags, the thinner stirrups are pressed down and embedded into the cotton bags, causing the cotton bags on both sides of the stirrups to cover them, making it difficult to insert the cutting blades of the wire cutters into the stirrups. Currently, the cutting operation is achieved by pressing down on the cotton bags on both sides of the stirrups with the wire cutters, exposing the stirrups to the outside. Because the stirrups are deeply embedded in the cotton bags after being bound, the operator needs to apply considerable downward pressure to press down on the cotton bags, resulting in a significant physical burden when cutting multiple finished cotton bags. At the same time, because the stirrups are tightly bound to the cotton bags, the surface of the cotton bags is also cut during the process of cutting the stirrups, allowing the wire cutters to penetrate into the finished cotton and cause contamination. Furthermore, the shavings generated during the cutting of the wire stirrups also fall into the finished cotton, and the contaminated shavings affect the quality in subsequent yarn spinning and textile production. Utility Model Content

[0005] To address the aforementioned problems, this application aims to provide an auxiliary device for opening finished cotton bags. By using an arc-shaped plate, the downward pressure is eliminated during the use of cutting pliers, and a horizontal cutting force is applied unilaterally. This effectively improves the convenience of the cutting operation, reduces the physical burden on the operator when pressing down on the cotton bag, and also prevents the cutting pliers from tearing the cotton bag.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: an auxiliary device for opening finished cotton bags, wherein the cotton bag is circumferentially bound with multiple hoops, and the hoop ties are cut by cutting pliers to open the bag. The pliers have a left and right blades that are hinged to each other. The auxiliary device is an arc-shaped plate that is adapted to the outer shape of the left and right blades of the pliers and can cover the left and right blades from the outside.

[0007] Preferably, the thickness of the arc-shaped plate gradually decreases from its center toward both ends, and the inner and outer surfaces meet at the ends in an arc.

[0008] Preferably, the width of the arc-shaped plate gradually decreases from its center toward both ends, and the ends are in the shape of a circular arc plane.

[0009] Preferably, protruding ribs are provided on both sides of the arc plate along the length direction. The protruding ribs drive the stirrups to be completely located inside the left and right blades, and the symmetrical protruding ribs form a chip accumulation groove with an inner width greater than the hinge thickness of the left and right blades.

[0010] The beneficial effects of this application are as follows: The arc-shaped plate disclosed in this application can be inserted into the bottom of the stirrup and press down the cotton bag, so that the shears abut against the surface of the arc-shaped plate and cut the stirrup. This eliminates the need to apply downward pressure during the use of the shears, and instead applies a horizontal cutting force, thereby effectively improving the convenience of the cutting operation and reducing the physical burden on the operator when pressing down the cotton bag. At the same time, the arc-shaped plate also avoids the problem of the shears tearing the cotton bag, and the upper surface of the arc-shaped plate can catch the shearing chips generated during the cutting process, preventing the chips from falling into the finished cotton.

[0011] By setting protruding ridges on the curved plate, the bottom side of the stirrup can be completely located within the left and right cutting edges, thus enabling a complete shearing operation. At the same time, the chip accumulation groove formed by the two protruding ridges can prevent the chips generated during the stirrup shearing process from falling from the sides of the curved plate into the finished cotton, thus blocking the chips.

[0026] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] See attached document Figures 4-13 The illustration shows an auxiliary device for opening a finished cotton bag. The cotton bag 1 is circumferentially bound with multiple reinforcing ribs 2. The bag is opened using cutting pliers 3, which have hinged left and right blades 31 and 32. Currently, by using the handle of the cutting pliers, the left and right blades 31 and 32 are driven to press down on the cotton bag on both sides of the reinforcing ribs 2, causing the reinforcing ribs 2 to protrude from the cotton bag and extend into the left and right blades 31 and 32. By driving the handle, the left and right blades 31 and 32 on both sides are hinged closer together, thus achieving the cutting operation of the reinforcing ribs 2.

[0028] To address the physical burden of current cutting operations and the resulting contamination and debris from tearing the cotton bag, this application provides an auxiliary device, such as... Figure 4 As shown, the auxiliary device is an arc-shaped plate 4 (preferably made of metal). This arc-shaped plate 4 is adapted to the outer shape of the left blade 31 and the right blade 32 of the shears 3, and can cover the left blade 31 and the right blade 32 from the outside. The usage process is as follows: Figure 5-7 As shown, hold the curved plate and place one end of it in contact with one side of the stirrup 2. Then, drive the curved plate to insert it along the bottom surface of the stirrup, and continue inserting the curved plate 4 until the curved plate forms a shape like... Figure 7 As shown, it is located below the stirrup 2 and above the cotton bag. Then, move the shears 3 down, as... Figure 8 As shown, the left blade 31 and the right blade 32 are brought into contact with the arc plate 4, and the stirrup 2 is located between the left blade 31 and the right blade 32. In this state, the arc plate 4 presses down on the cotton bags on both sides of the stirrup 2 by being located below the stirrup 2, so that the cotton bags are exposed outside the stirrup. This drives the handle of the shearing pliers 3, and the left blade 31 and the right blade 32 slide close along the surface of the arc plate 4 to achieve the shearing operation of the stirrup.

[0029] Therefore, the arc-shaped plate 4 allows for the downward pressure of the cotton bags on both sides of the stirrup 2 before shearing, and allows the cotton bags to protrude from the stirrup 2. During the use of the shearing pliers 2, it is not necessary to apply downward pressure. Instead, a horizontal shearing force is applied unilaterally, which effectively improves the convenience of the shearing operation and reduces the physical burden on the operator to press down the cotton bags. At the same time, the arc-shaped plate 4 also avoids the problem of the shearing pliers 3 tearing the cotton bags. Furthermore, the upper surface of the arc-shaped plate 4 can catch the shearing chips generated during shearing, preventing the chips from falling into the finished cotton.

[0030] Because the stirrups press the cotton bag down tightly, to facilitate the insertion of the curved plate 4 between the stirrup 2 and the cotton bag, as follows: Figure 4 As shown, the thickness of the arc-shaped plate 4 gradually decreases from its center towards both ends, and the inner and outer surfaces meet at the ends with an arc. The thinned ends and the arc-shaped connection structure at the ends allow the ends of the arc-shaped plate 4 to smoothly penetrate between the stirrups and the cotton bag, enabling the arc-shaped plate to be inserted smoothly and quickly. The thicker middle section ensures the bending strength of the arc-shaped plate 4, preventing the cotton bag from causing the ends of the arc-shaped plate 4 to bend inwards, thus preventing the shears from being inserted into the arc-shaped plate 4.

[0031] Because the stirrups are tied circumferentially, the wider curved plate 4 cannot be smoothly inserted from below the stirrups 2 of the curved structure. Therefore, to facilitate the smooth insertion of the curved plate 4, as follows: Figure 11 As shown, the width of the arc-shaped plate 4 gradually decreases from its center towards both ends, and the ends are in the shape of a rounded plane. The narrower ends and the matching rounded end structure facilitate insertion under the stirrups of the arc-shaped structure.

[0032] like Figure 9 As shown, during the above-mentioned shearing operation, since the bottom of the stirrup 2 and the tips of the left blade 31 and right blade 32 all contact the same arc-shaped surface of the arc-shaped plate 4, the bottom of the stirrup 2 may not be completely sheared during the shearing process. Therefore, to solve this problem, as follows... Figure 10-12As shown, protruding ribs 41 are provided on both sides of the arc-shaped plate 4 along the length direction. These protruding ribs 41 are preferably pressed from the back side of the arc-shaped plate 4. The protruding ribs 41 drive the stirrups 2 to be completely located within the left blade 31 and right blade 32, and the symmetrical protruding ribs 41 form a chip accumulation groove 4a with an inner width greater than the hinge thickness of the left blade 31 and right blade 32. During the cutting process, the tips of the left blade 31 and right blade 32 of the shearing pliers 3 are within the chip accumulation groove 4a and still located on the upper surface of the arc-shaped plate 4, while the stirrups 2 are pushed upwards by the protruding ribs 41. Figure 12 (As shown by the middle arrow), this allows the bottom side of the stirrup 2 to be completely within the left blade 31 and the right blade 32, thus enabling a complete shearing operation. Meanwhile, as... Figure 13 As shown, the chip groove 4a formed by the two protruding ridges 41 can restrict the chips generated during the shearing of the stirrups from falling from the side of the arc plate 4 into the finished cotton, thus blocking the chips.

[0033] The principle of this application is as follows: When cutting the hoop 2 of the finished cotton bag using the auxiliary device disclosed in this application, the arc plate 4 is held so that one end passes through the bottom of the hoop 2 and the top of the cotton bag, and the cotton bag is pressed down by the arc plate 4 and located below the hoop 2; then the cutting pliers are moved down so that the left blade 31 and the right blade 32 contact the surface of the arc plate 4, and then the hoop 2 is cut by driving the handle of the cutting pliers.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope of protection, and all such changes and modifications fall within the scope of protection claimed by this utility model.
