DETAILED DESCRIPTION

[0030] The specific implementation of the utility model will be further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model.

[0031] "Top surface", "bottom", "bottom surface" take the normal use state of the electrospinning receiving device as reference, only for the convenience of describing the utility model and simplifying the description, and not indicating or implying that the device or element referred to must have a specific orientation, structure and operation in a specific orientation, therefore, it cannot be understood as a limitation on the utility model.

[0032] As shown in Figure 2 and 3 , an electrospinning receiving device for preparing a water treatment nanofiber membrane substrate, comprising a mounting seat 1; a rotating shaft 203 is rotatably arranged on the mounting seat 1 about its own axis, and the mounting seat 1 is fixedly connected with a first driving part 201 in transmission connection with the rotating shaft 203; two rotating discs 202 are coaxially fixed on both ends of the rotating shaft 203 respectively; at least two rollers 4, the rollers 4 are parallel to each other with the rotating shaft 203, and are rotatably arranged between the two rotating discs 202 about their own axes, each roller 4 is distributed at equal intervals around the rotating shaft 203, and the roller 4 is detachably connected with the rotating disc 202.

[0033] The receiving device is used for receiving the formed spinning in the electrospinning process, and forming a nanofiber membrane on the receiving device, wherein the first driving member 201 is a self-locking motor, which is installed on the mounting seat 1 and used for driving the rotating disc 202 to rotate, so as to realize the switching of the positions between the rollers 4; when the roller 4 receives the spinning, the spinning is uniformly distributed on the outer surface of the roller 4 through the rotation of the roller 4, so as to improve the quality of the formed fiber membrane; when the fiber membrane production is completed, the roller 4 rotates around the rotating shaft 203, so as to realize the switching of the positions of the rollers 4, and the cleaned roller 4 is sent to the working position for receiving the spinning; and the other roller 4 rotates to the idle position, so that the fiber membrane on the roller 4 can be taken off, and the roller 4 can be cleaned and wound with new release paper; in this way, the electrospinning equipment can be continuously operated, and the production efficiency of the equipment is improved.

[0034] In the receiving device, the number of the rollers 4 is two, so that the switching of the rollers can be realized, the equipment can be continuously operated, and the cost of the equipment can be reduced, so that the production cost is reduced; the two rollers 4 are symmetrically arranged about the rotating shaft 203, so that the stability of the rotation of the rotating disc 202 and the roller 4 can be improved, and the shaking of the equipment is reduced; the rotating discs 202 arranged on the two sides also have the function of blocking the airflow, so that the influence of the airflow on the direction of the spinning injection is reduced, the uniformity of the receiving of the spinning by the receiving device is improved, and the quality of the produced fiber membrane is improved.

[0035] Further improvement is that, as shown in Figure 4 the both ends of the roller 4 are connected with the rotating disc 202 through the sliding seat 401, the roller 4 is rotationally connected with one of the sliding seats 401, and the other sliding seat 401 is provided with a power mechanism 403 which is in driving connection with the roller 4. The sliding seat 401 is detachably connected with the rotating disc 202, so that the roller 4 can be conveniently detached, which is beneficial to taking off the formed fiber membrane from the roller 4, and the convenience of cleaning and maintaining the roller 4 is improved; the power mechanism 403 is arranged for driving the roller 4 to rotate, so that the spinning is uniformly deposited on the roller 4.

[0036] Further improvement is that, as shown in Figure 7 the roller 4 is coaxially provided with a support shaft 405 which is fixedly connected with the sliding seat 401, and the roller 4 is connected with the support shaft 405 through a bearing. The roller 4 is in tubular structure, and is made of stainless steel. The stainless steel has good conductivity, which can effectively conduct the electric charge away. In the electrospinning process, when the spinning with electric charge flies to the roller 4 under the action of the electric field, the stainless steel roller 4 can quickly conduct the electric charge away, so as to avoid the influence of the accumulation of the electric charge on the deposition of the fiber, and the stainless steel also has good corrosion resistance, which can prolong the service life; the support shaft 405 is used for supporting the roller 4, and the bearing is used for connecting the support shaft 405 and the roller 4, and improving the smoothness of the rotation of the roller 4.

[0037] Further improvement is that, as shown inFigure 4 As shown in the figure, the power mechanism 403 is inserted into one end of the roller 4. The power mechanism 403 inserted into the roller 4 can effectively support one end of the roller 4, and when both ends of the roller 4 are reliably supported, the stability of the roller 4 can be greatly improved. The power mechanism 403 is arranged inside the roller 4, which can reduce the space occupation of the power mechanism 403 and make the use of the equipment more flexible and convenient.

[0038] Further improvement is that, as shown in the figure, Figure 5 The power mechanism 403 includes a rotating sleeve 4031 coaxially inserted into the end of the roller 4. The inner side of the rotating sleeve 4031 is provided with a support 4033 fixedly connected with the sliding seat 401. The support 4033 is fixedly connected with a second driving member 4034 for driving the rotating sleeve 4031 to rotate.

[0039] Specifically, the second driving member 4034 is a servo motor, which is fixedly connected with the sliding seat 401 through the support 4033. The rotating sleeve 4031 is fixed on the driving shaft of the servo motor and is driven to rotate by the servo motor. At the same time, the servo motor is covered inside the rotating sleeve 4031, which can realize the protection of the servo motor. In use, the rotating sleeve 4031 is inserted into one end of the roller 4, and the friction between them makes the rotating sleeve 4031 drive the roller 4 to rotate. At the same time, the rotating sleeve 4031 also stably supports the end of the roller 4, and makes the disassembly and assembly of the rotating sleeve 4031 and the roller 4 more convenient.

[0040] Further improvement is that, as shown in the figure, Figure 5 and 6 The outer periphery of the rotating sleeve 4031 is provided with a limiting groove 4032 along the axial direction. The inner wall of the end of the roller 4 is provided with a limiting strip 404 along the axial direction. The limiting strip 404 is inserted into the limiting groove 4032. The limiting groove 4032 and the limiting strip 404 cooperate with each other to increase the friction between them when the rotating sleeve 4031 drives the roller 4 to rotate, prevent slipping between them, and further improve the stability of transmission between them and the stability of rotation of the roller 4.

[0041] Further improvement is that, as shown in the figure, Figure 5 The end of the rotating sleeve 4031 close to the roller 4 is in a semispherical structure or a conical structure. Both the spherical structure and the cylindrical structure can play a guiding role, which facilitates the butt joint between the rotating sleeve 4031 and the roller 4 and improves the convenience of assembly between them.

[0042] Further improvement is that, as shown in the figure, Figure 1 Between the two rotating discs 202, an annular conveying belt 3 is further arranged. Each roller 4 is arranged on the inner side of the conveying belt 3 and is in rolling connection with the conveying belt 3.

[0043] The surface of the roller 4 is curved, and the effective receiving area is relatively small compared with the flat plate receiver. During the spinning process, part of the spinning jet may not be accurately deposited on the surface of the roller 4 due to the influence of factors such as electric field distribution, airflow, etc., thereby resulting in low receiving efficiency of the spinning. Therefore, the conveying belt 3 is arranged between the two rollers 4, the surface of the part of the conveying belt 3 between the two rollers 4 is a flat structure, and the receiving efficiency of the spinning can be improved by directing the spinning to the flat structure part. Meanwhile, the conveying belt 3 can be moved by the roller 4 to uniformly lay the spinning on the surface of the conveying belt 3, so that a larger fiber membrane can also be produced. The angle of the side of the conveying belt 3 for receiving the spinning can be adjusted by the rotation of the rotating disc 202, thereby further improving the receiving efficiency of the spinning. The above conveying belt 3 is a conveying belt with conductive performance.

[0044] Further improvement is that, as shown in Figure 3 the side of the rotating disc 202 close to the rotating shaft 203 is provided with a sliding rail 204 along the radial direction thereof, and the sliding seat 401 is in sliding cooperation with the sliding rail 204. The sliding rail 204 and the sliding seat 401 are in cooperation with each other to realize the disassembly and assembly between the roller 4 and the rotating disc 202, and the relative position between the roller 4 and the rotating disc 202 can be adjusted. By adjusting the distance between the two rollers 4, conveying belts 3 with different lengths can be arranged on the two rollers 4, so that the size of the receiving spinning surface can be controlled, and the size of the fiber membrane can be controlled by controlling the surface area of the conveying belt 3, thereby improving the practicability of the equipment.

[0045] Further improvement is that, as shown in Figure 5 the sliding seat 401 is provided with a sliding groove 406 matched with the sliding rail 204, the width of the opening of the sliding groove 406 is smaller than the width of the inside of the sliding groove 406, the sliding seat 401 is threadedly connected with a locking screw 402, and the front end of the locking screw 402 abuts against the sliding rail 204. The sliding groove 406 is a T-shaped groove or a dovetail groove to improve the stability of the connection between the sliding seat 401 and the sliding rail 204, and the locking screw 402 can realize the locking and unlocking between the sliding seat 401 and the sliding rail 204, thereby realizing the adjustment of the position of the sliding seat 401 and the disassembly of the sliding seat 401, and improving the convenience of the maintenance of the equipment.

In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model.
