Description

Technical Field

[0001] This invention relates to a feeding device, and more particularly to a soft hopper and its manufacturing method. Background Technology

[0002] A silo is a device mainly used for temporary storage of materials. The bottom of the silo is usually equipped with a discharge cone. When the material stored in the silo needs to be transferred, the material stored in the silo is discharged from the discharge cone.

[0003] As shown in patents CN201920190646.9 and CN202220799119.X, the discharge cones at the bottom of silos used in the existing material conveying field are made of stainless steel 304 or 316. The interior of such stainless steel discharge cones needs to be mirror polished, resulting in high material costs, large product weight, and labor-intensive installation. Moreover, the overall shape is large, cannot be bent, and has high requirements for installation space, resulting in poor flexibility. In particular, it is not easy to solve the problem when material blockage occurs in the discharge cone. Furthermore, it occupies a lot of space during transportation, is inconvenient to move, and increases transportation costs. Summary of the Invention

[0004] Therefore, it is necessary to provide a soft bucket to address the technical problems of existing stainless steel feeding cone buckets, such as high material cost, large product weight, poor flexibility, inconvenient transportation, and easy material blockage.

[0005] The technical solution of this invention is as follows:

[0006] A soft container, characterized in that it comprises a main body, a fixing part for shaping the main body, a first flange at one end of the main body, a second flange at the other end of the main body, a first silicone layer attached to the inner side of the main body, a second silicone layer connecting one end of the main body to the first flange, and a third silicone layer connecting the other end of the main body to the second flange. The main body, the first flange, and the second flange are made of canvas, and the first silicone layer, the second silicone layer, and the third silicone layer are cured liquid silicone.

[0007] In one embodiment, the main body is formed by rolling up a sheet of fabric, with the two sides of the fabric overlapping and bent to one side to form a three-layer structure, and the fixing part seals and fixes the three-layer structure.

[0008] In one embodiment, the fixing part is a sewn thread.

[0009] In one embodiment, the first silicone layer is disposed on the inside of the body and covers the stitching.

[0010] In one embodiment, the main body includes a main segment and a plurality of first fixed segments connected to one end of the main segment and a plurality of second fixed segments connected to the other end of the main body. The main segment is generally arranged in a funnel shape that is larger at the top and smaller at the bottom. A first silicone layer is attached to the inner side of the main segment. An upper opening is formed at the upper end of the main segment and a lower opening is formed at the lower end of the main segment.

[0011] In one embodiment, the first fixing segment of the main body is connected to the opening edge of the upper opening, and the second fixing segment of the main body is connected to the opening edge of the lower opening.

[0012] In one embodiment, the first fixed segments are evenly spaced apart, and a first gap is formed between two adjacent first fixed segments. The first gap is V-shaped. The second fixed segments are evenly spaced apart, and a second gap is formed between two adjacent second fixed segments. The second gap is V-shaped.

[0013] In one embodiment, there are two first flanges, the first fixing section is disposed between the two first flanges, the two first flanges seal the first gap, the first fixing section is connected to the first flange through the second silicone layer, and a first fold is formed between the two first flanges, the first fixing section and the second silicone layer.

[0014] In one embodiment, there are two second flanges, and the second fixing section is disposed between the two second flanges. The two second flanges seal the second gap opening, and the second fixing section is connected to the second flanges through a third silicone layer. A second flange is formed between the two second flanges, the second fixing section, and the third silicone layer.

[0015] This invention also provides a method for manufacturing a soft bucket, characterized by comprising the following steps:

[0016] Cutting: The canvas material is cut into a fan-shaped main body, a first flange set in a ring, and a second flange set in a ring. Multiple cuts are made on the upper and lower edges of the main body to form multiple cuts on the upper and lower edges of the main body.

[0017] The main body is rolled into a funnel shape, and the left and right edges of the main body overlap and bend to one side to form a three-layer structure. The three-layer structure is then sealed and fixed by sewing.

[0018] Apply adhesive: Apply a mixture of liquid silicone and curing agent to the inner surface of the funnel-shaped main body, and apply the mixture of liquid silicone and curing agent to the first flange and the second flange.

[0019] Folding and fixing: the upper and lower sides of the main body prototype are bent outward along the cut, so that the main body prototype forms a main body segment and several first fixed segments connected to one end of the main body segment and several second fixed segments connected to the other end of the main body segment. Then, two first flanges are installed on the first fixed segments and two second flanges are installed on the second fixed segments.

[0020] The liquid silicone is cured, forming a first silicone layer on the inside of the main body section, a second silicone layer between the first fixed section and the first flange, and a third silicone layer between the second fixed section and the second flange.

[0021] The beneficial effects of the flexible hopper of this invention are as follows: the flexible hopper can be used in place of a metal hopper; the canvas after silicone curing has excellent sealing, waterproofing, high temperature resistance, and tensile strength, while also having good tear resistance and elongation. Furthermore, the flexible hopper of this invention is lightweight and foldable, making it both economical and convenient, effectively reducing material costs, installation costs, and transportation costs. In addition, the flexible hopper of this invention effectively solves the problem of material blockage; when material blockage occurs inside the hopper, it can be resolved by tapping the outer wall.

An upper opening 111 is formed at the upper end of the main body segment 11, and a lower opening 112 is formed at the lower end of the main body segment 11. The first fixing segments 12 of the main body segment 10 are connected to the opening edge of the upper opening 111. The first fixing segments 12 are evenly spaced apart, and a first gap 121 is formed between two adjacent first fixing segments 12. In this embodiment, the first gap 121 is a V-shaped opening. The second fixing segments 13 of the main body segment 10 are connected to the opening edge of the lower opening 112. The second fixing segments 13 are evenly spaced apart, and a second gap 131 is formed between two adjacent second fixing segments 13. In this embodiment, the second gap 131 is a V-shaped opening.

[0037] Please continue reading. Figure 4 , Figure 5 The present invention also provides a method for manufacturing a soft bucket, which includes the following steps:

[0038] (1) Cutting: The canvas material is cut into a fan-shaped main body prototype 10', a first flange 20 arranged in a ring, and a second flange 30 arranged in a ring. The upper and lower edges of the main body 10 are arc-shaped. Multiple cuts are made on the upper and lower edges of the main body 10 to form multiple cuts 14 on the upper and lower edges of the main body 10.

[0039] (2) Shaping: The main body prototype 10' is rolled into a funnel shape. The left and right sides of the main body prototype 10' are overlapped and bent to one side to form a three-layer structure. The three-layer structure is sealed and fixed by sewing.

[0040] (3) Mixing: Mix liquid silicone and curing agent in a ratio of (40-50):1 and stir evenly.

[0041] (4) Apply adhesive: Apply a mixture of liquid silicone and curing agent to the inner side of the funnel-shaped main body prototype 10', and apply the mixture of liquid silicone and curing agent to the first flange 20 and the second flange 30.

[0042] (6) Folding and fixing: The upper and lower parts of the main body prototype 10' are bent outward along the cut 14, thereby forming the main body segment 11 of the main body 10 and several first fixed segments 12 connected to one end of the main body segment 11, and several second fixed segments 13 connected to the other end of the main body 10. A first gap 121 is formed between two adjacent first fixed segments 12, and a second gap 131 is formed between two adjacent second fixed segments 13. The main body segment 11 is generally arranged in a funnel shape, which is larger at the top and smaller at the bottom. An upper opening 111 is formed at the upper end of the main body segment 11, and a lower opening 112 is formed at the lower end of the main body segment 11. Then, two first flanges 20 are installed on the first fixed segments 12, and two second flanges 30 are installed on the second fixed segments 13, thereby forming a soft funnel prototype. The two first flanges 20 seal the first gap 121, and the two second flanges 30 seal the second gap 131.

[0043] (7) Curing: Place the soft-shell prototype for 24 hours. During this time, the main body section 11 remains partially open to prevent the liquid silicone on the inside of the main body section 11 from sticking together. After curing, the liquid silicone on the inside of the main body section 11 forms a first silicone layer 40, the liquid silicone between the first fixing section 12 and the first flange 20 forms a second silicone layer 50, and the liquid silicone between the second fixing section 13 and the second flange 30 forms a third silicone layer 40. A first folded edge 70 is formed between the two first flanges 20, the first fixing section 12, and the second silicone layer 50, and a second folded edge 80 is formed between the two second flanges 30, the second fixing section 13, and the third silicone layer 40.

[0044] (8) Drilling holes: Drill a first functional hole 71 on the first folded edge 70. The first functional holes 71 are evenly spaced on the first folded edge 70. Drill a second functional hole 81 on the second folded edge 80. The second functional holes 81 are evenly spaced on the second folded edge 80.
