Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spinning, in particular to a receiving device and electrostatic spinning equipment. Background Art

[0002] Electrospinning is a process in which a spinning solution is formed into filaments under the influence of an electric field and then deposited into a film material. A receiving electrode is placed on one side of the receiving device. The filaments are first deposited on a receiving conveyor belt and then separated from it. Because the receiving electrode and the filaments are electrically charged, the receiving device must be well insulated to prevent the electric field from affecting other components of the spinning equipment.

[0003] Some existing receiving conveyor belts are constructed of insulating materials, providing a certain degree of insulation between the conveyor belt and the conveyor pulleys that drive the conveyor belt. However, under the influence of an electric field, the insulating conveyor belt will become charged. When the charge accumulates to a certain level, it will discharge into the equipment. This inadequate insulation can affect the operation of the receiving device and other components of the spinning equipment, even causing damage and creating safety issues. Utility Model Content

[0016] Preferably, an insulating member is provided between the receiving electrode plate and the base, and the receiving electrode plate is insulated from the base by the insulating member.

[0028] like Figure 1 and Figure 2 As shown, a receiving device includes a base 1, on which is provided a receiving electrode plate 2, which is insulated from the base 1. An active conveying roller 3 and a driven conveying roller 4 are rotatably connected to the base 1, and an insulating receiving belt 5 is wound around the active conveying roller 3 and the driven conveying roller 4. The receiving electrode plate 2 is located on the back side of the receiving surface of the insulating receiving belt 5. Taking downward spinning as an example, the upper side of the upper half of the insulating receiving belt 5 is the receiving surface, and the receiving electrode plate 2 is located on the lower side of the upper half of the insulating receiving belt 5. The receiving electrode plate 2 is connected to one pole of the electric field. During spinning, the fiber filaments are deposited on the insulating receiving belt 5 under the action of the electric field. The receiving electrode plate 2 can be grounded or connected to high voltage.

[0029] The outer periphery of the active conveying roller 3 is provided with a first insulating structure, and the outer periphery of the driven conveying roller 4 is provided with a second insulating structure. The active conveying roller 3 is insulated from the insulating receiving belt 5 through the first insulating structure, and the driven conveying roller 4 is insulated from the insulating receiving belt 5 through the second insulating structure.

[0030] The receiving electrode plate 2 is insulated from the base 1, and the voltage and current of the receiving electrode plate 2 are not transmitted to the base 1; at the same time, the insulating receiving belt 5 is insulated from the active conveying roller 3 by a first insulating structure, and the insulating receiving belt 5 is insulated from the driven conveying roller 4 by a second insulating structure. Although the insulating receiving belt 5 will carry an electric charge under the action of the electric field, the insulation effect between the insulating receiving belt 5 and the active conveying roller 3 and the driven conveying roller 4 is improved under the insulation effect of the first insulating structure and the second insulating structure, and the difficulty of the charge on the insulating receiving belt 5 to discharge to the active conveying roller 3 and the driven conveying roller 4 is increased, thereby improving the stability and safety of the spinning equipment.

[0031] In some specific embodiments, the active conveying roller 3 is a first rubber-coated roller, which includes a first outer rubber ring 31 located on the outer periphery. The middle part of the first rubber-coated roller is made of metal to improve the structural strength. The first insulating structure includes the first outer rubber ring 31.

[0032] The active conveying roller 3 is a rubber-coated roller, and the first outer rubber ring 31 of the first rubber-coated roller is used as the first insulating structure, so the structure is relatively simple.

[0033] Furthermore, the thickness h1 of the first outer rubber ring 31 is 50-200 mm. When the first outer rubber ring 31 is within this thickness range, the charge isolation effect is better and the diameter of the first rubber-coated roller is not too large.

[0034] Furthermore, the first outer rubber ring 31 is made of insulating and corrosion-resistant materials such as nylon, polyethylene, silicone or polytetrafluoroethylene.

[0035] In some specific embodiments, the driven conveyor roller 4 is a second rubber-coated roller, which includes a second outer rubber ring 41 located on the outer periphery. The middle part of the second rubber-coated roller is made of metal to improve the structural strength, and the second insulating structure includes the second outer rubber ring 41.

[0036] The driven conveying roller 4 is a rubber-coated roller, and the second outer rubber ring 41 of the second rubber-coated roller is used as the second insulating structure, which is relatively simple in structure. The thickness and material of the second outer rubber ring 41 can be set with reference to the thickness and material of the first outer rubber ring 31.

[0037] In some specific embodiments, referring to Figure 2 A first insulating mounting seat 11 and a second insulating mounting seat are fixedly connected to the base 1, the active conveying roller 3 is rotatably connected to the first insulating mounting seat 11, the active conveying roller 3 is insulated from the base 1 through the first insulating mounting seat 11, and the driven conveying roller 4 is rotatably connected to the second insulating mounting seat, and the driven conveying roller 4 is insulated from the base 1 through the second insulating mounting seat.

[0038] The active conveyor roller 3 and the driven conveyor roller 4 are insulated from the base 1 by a first insulating mounting seat 11 and a second insulating mounting seat, respectively. This further increases the difficulty of discharging the charge on the insulating receiving belt 5 to the base 1 via the active conveyor roller 3 and the driven conveyor roller 4, thereby improving the stability and safety of the spinning equipment. The active conveyor roller 3 is rotatably connected to the first insulating mounting seat 11 via a bearing, and the driven conveyor roller 4 is rotatably connected to the second insulating mounting seat via a bearing.

[0039] In some specific embodiments, an insulating member 6 is provided between the receiving electrode plate 2 and the base 1 , and the receiving electrode plate 2 is insulated from the base 1 by the insulating member 6 .

[0040] Furthermore, the height h2 of the insulating member 6 is 5-100 cm. When the insulating member 6 is within this height range, the effect of isolating the electric field is better.

[0041] In another aspect, an electrospinning device having the above-mentioned receiving device is provided. The electrospinning device includes a frame and a spinneret assembly. The base is fixed to the frame. The spinneret assembly is directly opposite the receiving surface of the insulating receiving belt 5. A spinning electric field is formed between the spinneret assembly and the receiving electrode plate 2. The spinneret assembly ejects a spinning solution, which is deposited on the insulating receiving belt 5 under the action of the spinning electric field.

[0042] By adopting the above-mentioned receiving device, the insulation effect between the insulating receiving belt 5 and the active conveying roller 3 and the driven conveying roller 4 can be improved, and the difficulty of the charge on the insulating receiving belt 5 to discharge to the active conveying roller 3 and the driven conveying roller 4 is increased, thereby improving the stability and safety of the electrospinning equipment.

[0043] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
