Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ton bags, in particular to a koji powder packaging and transfer bag. BACKGROUND

[0002] In the production process of liquor, the packaging and transfer of koji powder are often involved. In the prior art, when the koji powder is transferred, the packaging tool of the koji powder can be a sack or a ton bag. However, the sack has many pores on the surface due to the weaving process, and the koji powder is easy to produce a large amount of dust during packaging and unloading, which affects the working environment. Although the koji powder is packaged in the ton bag, it is not easy to produce dust, but the conventional ton bag is usually used for transferring granular materials such as sorghum and wheat. The broken degree of the granular material is relatively low, and the relatively fast unloading speed can be ensured during unloading. However, when the ton bag is used to transfer the koji powder with high broken degree, the koji powder has poor flowability (it has been verified that the flowability of the koji powder is worse than that of flour), and the unloading speed is slow. CONTENT OF THE UTILITY MODEL

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0027] The present application provides a curved powder packaging and transferring bag, as shown in Figures 1 to 3 The curved powder packaging and transferring bag comprises:

[0028] The ton bag body 100 is provided with a square cross section;

[0029] The feed inlet 200 is located at the top of the ton bag body 100 and is connected to the interior of the ton bag body 100.

[0030] The discharge port 300 has a circular cross-section and is located at the bottom of the ton bag body 100 and is connected to the interior of the ton bag body 100.

[0031] The ratio of the side length of the ton bag body 100 to the diameter of the discharge port 300 is between 1.05 and 1.9.

[0032] In this embodiment, it is exemplarily illustrated that in the process of liquor production, koji powder can be transferred using koji powder packaging and transfer bags. During transfer, the koji powder at the designated location is first packaged in the koji powder packaging and transfer bag, and then the koji powder packaging and transfer bag is conveyed manually or mechanically. When the koji powder packaging and transfer bag is conveyed to the target location, the koji powder is unloaded from the koji powder packaging and transfer bag.

[0033] like Figure 1 As shown, in this embodiment, the koji powder packaging and transfer bag may include a ton bag body 100 for temporarily storing the koji powder. Since the ton bag body 100 typically includes at least one of cloth, plastic, and composite materials, it can prevent dust generation when the koji powder is packaged into the ton bag body 100. The ton bag body 100 can be configured as a square tube structure with a square cross-section. The inlet 200 can be located at the top of the ton bag body 100 and can be configured as a cylindrical tube structure. Specifically, one side of the top of the ton bag body 100 can be configured as a plane, and the inlet 200 can be located at the middle position of one side of the top of the ton bag body 100, that is, the inlet 200 can be coaxially configured with the ton bag body 100. When packaging the koji powder, the koji powder can be fed into the ton bag body 100 through the inlet 200. The outlet 300 can be located at the bottom of the ton bag body 100 and can also be configured as a cylindrical tube structure, which can also be coaxially configured with the ton bag body 100. Once the ton bag is delivered to the target location, the koji powder inside the ton bag can be unloaded from the discharge port 300.

[0034] like Figure 1As shown, the ratio of the side length of the ton bag body 100 to the diameter of the outlet 300 is preferably between 1.05 and 1.9. In this embodiment, the side length of the ton bag can be set to 950 mm, and the diameter of the outlet 300 can be set to 700 mm. In this case, the ratio of the side length of the ton bag body 100 to the diameter of the outlet 300 is approximately 1.36. Of course, in some embodiments, when the side length of the ton bag is set to 950 mm, the diameter of the outlet 300 can also be set to 900 mm, in which case the ratio of the side length of the ton bag body 100 to the diameter of the outlet 300 is approximately 1.06. In other embodiments, when the side length of the ton bag is set to 950 mm, the diameter of the outlet 300 can also be set to 500 mm, in which case the ratio of the side length of the ton bag body 100 to the diameter of the outlet 300 is 1.9.

[0035] Verification showed that when the ratio of the side length of the ton bag body 100 to the diameter of the outlet 300 is greater than 1.9, the diameter of the outlet 300 is relatively small. This can meet the unloading requirements of flour, but cannot meet the unloading requirements of koji powder. Specifically, the unloading speed of koji powder is too slow, and it is also prone to clumping and clogging of the outlet 300. Conversely, when the ratio of the side length of the ton bag body 100 to the diameter of the outlet 300 is less than 1.05, the diameter of the outlet 300 is relatively large, and its excessively fast discharge speed easily generates a large amount of dust.

[0036] It is understandable that by packaging the ton bag body 100 with the koji powder, this application can prevent the koji powder from generating excessive dust during and after packaging. Furthermore, by setting the cross-section of the ton bag body 100 to be rectangular and the cross-section of the discharge port 300 to be circular, and by setting the ratio of the side length of the ton bag body 100 to the diameter of the discharge port 300 to be between 1.05 and 1.9, it is possible to ensure that the koji powder can be unloaded quickly while also preventing the generation of dust during the unloading process. Thus, this application can effectively improve the problems of excessive dust and slow unloading speed when packaging and transporting koji powder.

[0037] Specifically, the ton bag body 100 includes an inner bag 110 and a thickening layer 120. The thickening layer 120 is provided with four pieces, and the inner bag 110 is located within the enclosing structure of the four thickening layers 120. The inner bag 110 is connected to all four thickening layers 120.

[0038] like Figure 1 and Figure 2As shown in this embodiment, the inner bag 110 is mainly used for packaging the koji powder and can be made of flexible fabric. The inlet 200 and outlet 300 can both be integrally formed with the inner bag 110, in which case the inlet 200 and outlet 300 are made of the same material as the inner bag 110. The inlet 200 is made of flexible fabric, allowing it to be fitted onto other shaped discharge ports during packaging, such as the rectangular discharge port of a telescopic chute; simultaneously, it allows the inlet 200 to be laid flat on one side of the top of the ton bag body 100 after packaging, preventing the koji powder from spilling due to the shaking of the ton bag body 100. The outlet 300 is also made of flexible fabric, making it easy to open and close, thus improving unloading efficiency.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the thickened layer 120 can be configured as a composite layer structure containing supporting materials such as a metal wire interlayer and a metal braided layer. The thickened layer 120 can consist of four pieces, all of which can be rectangular and of the same size. The four thickened layers 120 can be sequentially spliced ​​together to form a square tube-shaped structure. The inner bag 110 can be disposed within the enclosed structure of the four thickened layers 120, and the inner bag 110 can be connected to all four thickened layers 120. The connection between the inner bag 110 and the four thickened layers 120 can be by sewing. The thickened layer 120 mainly serves as a supporting structure, ensuring that the cross-section of the ton bag body 100 is square, and also facilitating the maintenance of the shape of the ton bag body 100 during the packaging and transport of the powder.

[0040] It is understood that by setting the ton bag body 100 as an inner bag 110 and four thickened layers 120 surrounding the inner bag 110, this embodiment can facilitate the ton bag body 100 to maintain its shape during the packaging and transportation of koji powder, so that the koji powder can be packaged into the inner bag 110 through the inlet 200; and it can also prevent the inner bag 110 from sagging due to the enlargement of the outlet 300 when the ton bag body 100 discharges koji powder from the inner bag 110 through the outlet 300, thereby improving the unloading speed. Thus, this embodiment can further improve the problems of large dust and slow unloading speed when packaging and transporting koji powder.

[0041] Specifically, the powder packaging and transfer bag also includes a connecting part 400, which connects the ton bag body 100 and the discharge port 300. The top of the connecting part 400 has the same cross-sectional shape as the ton bag body 100, and the bottom of the connecting part 400 has the same cross-sectional shape as the discharge port 300.

[0042] like Figure 1 and Figure 3As shown in this embodiment, the connecting part 400 can be configured as a tapered tubular structure that is wider at the top and narrower at the bottom. The shape of its top end can be the same as the cross-sectional shape of the ton bag body 100, i.e., a square; while the shape of its bottom end can be the same as the cross-sectional shape of the discharge port 300, i.e., a circle. With the aforementioned structure, the connecting part 400 can achieve a smooth transition between the ton bag body 100 and the discharge port 300. It is easy to see that the sides of the connecting part 400 arranged in any axial section are inclined; the axial section of the connecting part 400 is the longitudinal section passing through its axis.

[0043] It is understood that by setting the connecting part 400 in this embodiment, and adapting the shapes of the two ends of the connecting part 400 to the cross-sectional shapes of the ton bag body 100 and the discharge port 300 respectively, the connecting part 400 can be set in a conical shape, so that the powder concentrates towards the discharge port 300 during unloading, thereby further improving the discharge efficiency.

[0044] Specifically, the powder packaging and transfer bag also includes a cloth bag 500, and the ton bag body 100 includes a first side wall 130 and a second side wall 140 arranged opposite to each other. One end of the cloth bag 500 in the length direction is connected to the bottom of the first side wall 130, and the other end of the cloth bag 500 in the length direction is detachably connected to the bottom of the second side wall 140.

[0045] like Figure 1 and Figure 3 As shown in this embodiment, the two opposite sidewalls of the ton bag body 100 can be a first sidewall 130 and a second sidewall 140. Both the first sidewall 130 and the second sidewall 140 can be rectangular and have the same dimensions. A pocket 500 can be provided at the bottom of the ton bag body 100. The pocket 500 can be square and can also be made of fabric. The length direction of the pocket 500 can be along the first sidewall 130 of the ton bag body 100 towards the second sidewall 140. One end of the pocket 500 along its length direction can be connected to the first sidewall 130 of the ton bag body 100, and the connection method can be sewing. Preferably, the pocket 500 is sewn onto the thickened layer 120. The other end of the pocket 500 along its length direction can be detachably connected to the second sidewall 140 of the ton bag body 100.

[0046] like Figure 1 and Figure 3As shown, in this embodiment, when the koji powder is packaged into the ton bag body 100 through the feed inlet 200, the discharge outlet 300 can be closed, and then the lining 500 is connected to the second side wall 140 of the ton bag body 100. At this time, the lining 500 can support the koji powder inside the ton bag body 100. When the koji powder is unloaded from the ton bag body 100 through the discharge outlet 300, the lining 500 can be separated from the second side wall 140 of the ton bag body 100, and then the discharge outlet 300 can be opened.

[0047] It is understood that by providing a detachable tarpaulin 500 at the bottom of the ton bag body 100, this embodiment can improve the safety of the powder packaging and transportation, and at the same time prevent the inner bag 110 from falling during the packaging and transportation process.

[0048] More specifically, the ton bag body 100 is provided with a number of sliding buckles 600 on the bottom of the second side wall 140, and the bag cloth 500 is provided with a number of connecting straps 510 at the end connected to the second side wall 140, and the connecting straps 510 are threaded through and tied to the sliding buckles 600.

[0049] like Figure 1 and Figure 3 As shown in this embodiment, the detachable connection between the lining 500 and the second side wall 140 of the ton bag body 100 can be achieved by binding the connecting strap 510 and the sliding buckle 600. The sliding buckle 600 can be threaded through the bottom of the second side wall 140 of the ton bag body 100. It can be a circular structure and can be made of metal to provide high structural strength and load-bearing capacity. The connecting strap 510 can be a thickened cloth rope, strong enough to withstand human force. When it is necessary to connect the lining 500 to the second side wall 140 of the ton bag body 100, the connecting strap 510 is threaded through and bound to the sliding buckle 600; when it is necessary to separate the lining 500 from the second side wall 140 of the ton bag body 100, the connecting strap 510 is released from the sliding buckle 600 and removed from it. The connecting strap 510 and the sliding buckle 600 can each be set to a number. The number of connecting straps 510 and the number of sliding buckles 600 can be set at equal intervals, and the number of connecting straps 510 and the number of sliding buckles 600 can correspond one-to-one to avoid errors during the binding process.

[0050] It is understood that in this embodiment, the cloth 500 is detachably connected to the second side wall 140 of the ton bag body 100 by the sliding buckle 600 and the connecting strap 510, which makes the connection and separation of the cloth 500 and the ton bag body 100 more convenient, thereby improving the efficiency of packaging and transporting koji powder.

[0051] More specifically, the ton bag body 100 also includes a third side wall 150 and a fourth side wall 160 disposed opposite to and on both sides of the first side wall 130 and the second side wall 140. The ton bag body 100 also has a sliding buckle 600 at the bottom of the third side wall 150 and the fourth side wall 160, and the bag 500 also has connecting straps 510 at both ends in the width direction.

[0052] like Figure 1 and Figure 3 As shown in this embodiment, by way of example, the other two side walls of the ton bag body 100 can be the third side wall 150 and the fourth side wall 160, respectively. It is easy to see that the third side wall 150 and the fourth side wall 160 are arranged opposite to each other and are respectively arranged on both sides of the first side wall 130 and the second side wall 140. The two ends of the cloth 500 in the width direction can also be detachably connected to the third side wall 150 and the fourth side wall 160 of the ton bag body 100, and the detachable connection can also be in the form of a connecting strap 510 and a sliding buckle 600. At this time, the sliding buckle 600 can be arranged at the bottom of the third side wall 150 and the fourth side wall 160 of the ton bag body 100, and it can be set at equal intervals in several places; while the connecting strap 510 can be arranged at both ends in the width direction of the cloth 500, and it can also be set at equal intervals in several places, and can correspond one-to-one with the sliding buckle 600.

[0053] In this embodiment, when the koji powder is packaged into the ton bag body 100 through the feed inlet 200, the discharge outlet 300 can be closed. Then, the connecting strap 510 on the lining 500 is sequentially threaded through the sliding buckles 600 on the second side wall 140, third side wall 150, and fourth side wall 160 of the ton bag body 100 and tied to the sliding buckles 600 to improve the connection effect between the lining 500 and the ton bag body 100. When the koji powder is unloaded from the ton bag body 100 through the discharge outlet 300, the connecting strap 510 on the lining 500 can be sequentially released from the sliding buckles 600 on the second side wall 140, third side wall 150, and fourth side wall 160 of the ton bag body 100 and removed from the sliding buckles 600. Then, the discharge outlet 300 is opened.

[0054] It is understood that by providing sliding buckles 600 at the bottom of the third side wall 150 and the fourth side wall 160 of the ton bag body 100, and providing connecting straps 510 at both ends of the cloth 500 in the width direction, this embodiment can enable the cloth 500 to better support the koji powder inside the ton bag body 100 during the packaging and transportation process, thereby further improving the safety of the koji powder during packaging and transportation, and improving the anti-falling effect of the inner bag 110.

[0055] More specifically, the number of clips 600 on the second sidewall 140 is greater than the number of clips 600 on the third sidewall 150 and the fourth sidewall 160.

[0056] like Figure 1 and Figure 3 As shown in this embodiment, by way of example, during the unloading process, the connecting straps 510 at both ends of the cloth 500 in the width direction can be loosened from the sliding buckles 600 at the bottom of the third side wall 150 and the fourth side wall 160 and removed from the sliding buckles 600. At this time, the two ends of the cloth 500 in the length direction are still connected to the ton bag body 100, so that the cloth 500 still carries the powder in the ton bag body 100. Then, the connecting strap 510 at the end of the cloth 500 that is connected to the second side wall 140 in the length direction can be loosened from the sliding buckles 600 at the bottom of the second side wall 140 and removed from the sliding buckles 600, and then the discharge port 300 can be opened. If the connecting strap 510 at one end of the length of the hood 500 used to connect with the second side wall 140 is untied first, and then the connecting strap 510 at either end of the width of the hood 500 is untied, the supporting force exerted by the hood 500 on the bottom of the ton bag body 100 will be uneven, making the inner bag 110 prone to falling.

[0057] like Figure 1 As shown, in this embodiment, the number of sliding buckles 600 on the second sidewall 140 is preferably greater than the number of sliding buckles 600 on the third sidewall 150 and the fourth sidewall 160. For example, the number of sliding buckles 600 at the bottom of the ton bag body 100 can be ten, two of which can be respectively set at the connection between the second sidewall 140 and the third sidewall 150 and the connection between the second sidewall 140 and the fourth sidewall 160. The middle part of the second sidewall 140 can be provided with four sliding buckles 600, and the middle parts of the third sidewall 150 and the fourth sidewall 160 can each be provided with two sliding buckles 600. The connecting strap 510 is set on the pocket fabric 500 in the same way.

[0058] Of course, in some embodiments, the number of sliding buckles 600 at the bottom of the ton bag body 100 can also be other, such as nine, eleven, twelve, etc.

[0059] It is understood that by setting the number of sliding buckles 600 on the second sidewall 140 to be greater than the number of sliding buckles 600 on the third sidewall 150 and the fourth sidewall 160, this embodiment can ensure that the bag 500 still has a relatively high load-bearing capacity when the powder is unloaded and the two ends of the bag 500 in the width direction are separated from the ton bag body 100, but the bag 500 still supports the ton bag body 100 through its two ends in the length direction.

[0060] Specifically, the length of the blouse 500 is not less than the side length of the ton bag body 100, and is greater than the sum of the heights of the connecting part 400 and the discharge port 300.

[0061] likeFigure 1 As shown in this embodiment, the height of the connecting part 400 and the discharge port 300 is the distance between their two axial ends, and the length of the tarpaulin 500 is the distance between its two ends in the longitudinal direction. In this embodiment, the length of the tarpaulin 500 can preferably be no less than the side length of the ton bag body 100 and greater than the sum of the heights of the connecting part 400 and the discharge port 300. For example, the tarpaulin 500 can be set as a square, with both its length and width set to 950mm, while the height of the connecting part 400 can be set to 300mm, and the height of the discharge port 300 can be set to 400mm. When the detachable end of the tarpaulin 500 body in the longitudinal direction is connected to the second sidewall 140, the tarpaulin 500 can at least completely cover the bottom of the ton bag body 100.

[0062] It is understood that by reasonably setting the length of the sling 500 and the height of the connecting part 400 and the discharge port 300, this embodiment can ensure that the sling 500 completely covers the connecting part 400 and the discharge port 300 during the packaging and transportation of the powder, thereby ensuring the load-bearing effect of the sling 500 on the ton bag body 100.

[0063] Specifically, the powder packaging and transfer bag also includes lifting straps 700, which are provided on at least two opposite side walls of the ton bag body 100.

[0064] like ​ As shown in this embodiment, the lifting strap 700 can be used by automated equipment such as forklifts to lift the ton bag body 100, thereby reducing the labor intensity during packaging and transportation and improving work efficiency. The lifting strap 700 can be configured in a shape similar to an inverted "U". The open end of the "U" shape can extend from the top of the ton bag body 100 to the bottom of the ton bag body 100 and can be connected to the side wall of the ton bag body 100, and the connection method can still be sewing; while the closed end of the "U" shape can be spaced apart from the bottom of the ton bag body 100 to facilitate lifting. There can be two lifting straps 700, which can be respectively set on two opposite side walls of the ton bag body 100, such as the first side wall 130 and the second side wall 140, or the third side wall 150 and the fourth side wall 160. This embodiment uses the latter.

[0065] It is understood that this embodiment uses slings 700 to facilitate the automated hoisting of the ton bag body 100, making it more convenient to package and transport the koji powder using the ton bag body 100.

[0066] Specifically, the powder packaging and transfer bag also includes a tightening strap 800, which binds the discharge port 300 to close the discharge port 300, and the tightening strap 800 is loosened to open the discharge port 300.

[0067] like ​ As shown in this embodiment, the binding strap can be made of the same material as the connecting strap 510. It can be separately set from the discharge port 300, or it can be at least partially fixedly connected to the discharge port 300. This embodiment takes the former as an example. During the packaging and transportation of the koji powder, the binding strap binds the discharge port 300 to close it. When the koji powder is unloaded, the bag is tightened to loosen the discharge port 300 to open it.

[0068] It is understandable that this embodiment uses a tightening strap 800 to facilitate the opening and closing of the discharge port 300, thereby improving the efficiency of packaging and transporting the koji powder.

[0069] The implementation principle of the powder packaging and transfer bag provided in this application embodiment is as follows:

[0070] When the koji powder needs to be packaged and transported, the discharge port 300 is first secured with the tightening strap 800 to close it. Then, the tightening straps 800 on the tarpaulin 500 are sequentially threaded through the sliding buckles 600 at the bottom of the second side wall 140, the third side wall 150, and the fourth side wall 160, and secured to the sliding buckles 600. The koji powder is then fed into the ton bag body 100 through the inlet 200. When the koji powder is packaged, the ton bag body 100 can be lifted using the lifting straps 700 to move it to the target location, where the koji powder is then unloaded. When unloading, the fastening straps 800 on the cloth 500 can be loosened from the sliding buckles 600 at the bottom of the second side wall 140, the third side wall 150 and the fourth side wall 160 in sequence, and the fastening straps 800 can be taken out from the sliding buckles 600. Then the fastening straps 800 can be loosened to open the discharge port 300.

[0071] This application uses a ton bag body 100 to package the koji powder, which makes it less likely to generate a lot of dust during and after the packaging process. By setting the cross-section of the ton bag body 100 to be rectangular and the cross-section of the discharge port 300 to be circular, and setting the ratio of the side length of the ton bag body 100 to the diameter of the discharge port 300 to be between 1.05 and 1.9, it can ensure that the koji powder can be unloaded quickly while also making it less likely to generate dust during the unloading process. Thus, this application can effectively improve the problems of large dust and slow unloading speed when packaging and transporting koji powder.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
