Technical Field

[0001] This utility model relates to the field of electrostatic flash spinning, and in particular to an adjustable electrostatic flash spinning receiving device. Background Technology

[0002] Electrospinning is a method that uses a high-voltage electric field to stretch a polymer solution into ultrafine fibers, and it is widely used in biomedical materials, filtration materials, energy, and other fields. However, existing electrospinning receiving devices have some problems, such as being fixed and not adjustable, resulting in low fiber collection efficiency and susceptibility to contamination from dripping and splashing, which affects the quality of the fiber membrane.

[0003] In addition, after prolonged use, fibers tend to accumulate on the winding drum of traditional receiving devices, making them difficult to clean, which affects the service life and working efficiency of the equipment, and also makes it difficult to adjust the winding distance.

[0004] Therefore, it is necessary to propose an adjustable electrostatic flash spinning receiving device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable electrostatic flash spinning receiving device to solve the problems of traditional receiving devices where fibers tend to accumulate on the winding drum after prolonged use, making them difficult to clean, affecting the service life and working efficiency of the equipment, and making it difficult to adjust the winding distance.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable electrostatic flash spinning receiving device, comprising a winding drum, wherein two sliding rings are slidably disposed on the outer side of the winding drum, and a cleaning mechanism is provided on the side of the two sliding rings that are far apart from each other;

[0007] The cleaning mechanism includes two fixing plates, which are respectively fixed to the two sliding rings on opposite sides. A cleaning brush is fixed to the bottom of each fixing plate, and the bottom of the cleaning brush is attached to the outer surface of the winding drum.

[0008] Preferably, both ends of the take-up roller are provided with support plates, and the take-up roller is rotatably connected between the two support plates.

[0009] Preferably, a bidirectional lead screw is rotatably connected between the two support plates, the bidirectional lead screw is disposed above the winding drum, and a connecting plate is fixed to the top of each of the two sliding rings;

[0010] Two connecting plates are threaded onto the two reverse threads of the bidirectional lead screw, and a drive motor is fixed to one side of one of the support plates. The drive shaft of the drive motor is fixedly connected to one end of the bidirectional lead screw.

[0011] Preferably, each of the two fixing plates has a through groove on one side of its opposite side, through which the corresponding fixing plate and cleaning brush slide. The through groove extends through the other side of the fixing plate.

[0012] Preferably, the support plate has a groove on the side near the center of the winding drum, a spring is fixedly connected to the top of the groove, a pressure plate is fixedly connected to the bottom of the spring, and one end of the pressure plate extends out of the groove.

[0013] Preferably, the inner rings of both sliding rings are fixed with a sponge layer, and the inner rings of the sponge layer are attached to the outer side of the take-up roller.

[0014] Preferably, the two sliding rings have the same thickness and the same diameter.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In the actual operation of this utility model, the drive motor can drive the bidirectional lead screw to rotate. Simultaneously, the rotation of the bidirectional lead screw causes the two connecting plates to move their corresponding sliding rings closer together or further apart. This fixes the wound-up yarn between the two sliding rings, and the distance of the winding area can be expanded or shortened as needed.

[0017] 2. Furthermore, when the two sliding rings slide on the take-up cylinder, the outer side of the take-up cylinder can be cleaned by the sponge layer inside the sliding rings and the cleaning brush, reducing fiber residue and fiber accumulation, and protecting both sides of the limiting area.

[0018] 3. Each of the two fixed plates has a through groove on one side to allow the corresponding fixed plate and cleaning brush to slide through. The through groove extends through the other side of the fixed plate. The design of the through groove ensures that the cleaning mechanism will not interfere with other components during movement.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1 - Figure 3 An adjustable electrostatic flash spinning receiving device is shown, including a take-up roller 3. Two sliding rings 4 are slidably arranged on the outer side of the take-up roller 3. A cleaning mechanism is provided on the side of the two sliding rings 4 that are far apart from each other. Through the design of the cleaning mechanism, the fiber residue on the surface of the take-up roller 3 can be cleaned in real time to prevent fiber accumulation and thus improve fiber collection efficiency.

[0026] The cleaning mechanism includes two fixed plates 8, which are respectively fixed to the two sliding rings 4 on opposite sides. Each of the two fixed plates 8 has a cleaning brush 9 fixed to its bottom end. The bottom end of the cleaning brush 9 is attached to the outer surface of the winding drum 3. The cleaning brush 9 can move with the movement of the sliding rings 4 to clean the fiber residue on the surface of the winding drum 3 in real time, preventing fiber accumulation from affecting the subsequent collection effect.

[0027] Both ends of the winding drum 3 are provided with support plates 1, and the winding drum 3 is rotatably connected between the two support plates 1.

[0028] A bidirectional lead screw 6 is rotatably connected between two support plates 1. The bidirectional lead screw 6 is located above the winding drum 3. A connecting plate 5 is fixed to the top of each of the two sliding rings 4, and the two connecting plates 5 are threaded onto the two reverse threads of the bidirectional lead screw 6 respectively. A drive motor 2 is fixed to one side of one of the support plates 1, and the drive shaft of the drive motor 2 is fixedly connected to one end of the bidirectional lead screw 6.

[0029] In the actual operation of this invention, the drive motor 2 can drive the bidirectional lead screw 6 to rotate. Simultaneously, the rotation of the bidirectional lead screw 6 causes the two connecting plates 5 to move their corresponding sliding rings 4 closer together or further apart. This fixes the wound-up yarn between the two sliding rings 4. The distance of the winding area can be expanded or shortened as needed. The design of the bidirectional lead screw 6 and the sliding rings 4 allows the position of the cleaning mechanism to be adjusted as required, enhancing the flexibility and adaptability of the device.

[0030] Furthermore, when the two sliding rings 4 slide on the take-up cylinder 3, the outer side of the take-up cylinder 3 can be cleaned by the sponge layer 13 inside the sliding rings 4 and the cleaning brush 9, reducing fiber residue and fiber accumulation.

[0031] Each of the two fixed plates 8 has a through groove 7 on one side of its opposite side, through which the corresponding fixed plate 8 and cleaning brush 9 slide. The through groove 7 extends through the other side of the fixed plate 8. The design of the through groove 7 ensures that the cleaning mechanism will not interfere with other components during movement.

[0032] A groove 10 is provided on the side of the support plate 1 near the center of the winding drum 3. A spring 11 is fixedly connected to the top of the groove 10, and a pressure plate 12 is fixedly connected to the bottom of the spring 11. One end of the pressure plate 12 extends out of the groove 10.

[0033] Both sliding rings 4 have a sponge layer 13 fixed to their inner rings. The inner ring of the sponge layer 13 is attached to the outside of the take-up roller 3. The sponge layer 13 can absorb the static electricity generated during fiber collection and reduce the friction between the fiber and the take-up roller 3, thus protecting the integrity of the fiber.

[0034] The two sliding rings 4 have the same thickness and the same diameter, ensuring their stability and consistency when moving synchronously on the bidirectional lead screw 6. The moving design of the cleaning mechanism makes it easy to clean and maintain the device after use, extending the service life of the equipment.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
