Description

Technical Field

[0001] The invention relates to a bubble spinning device, belonging to the technical field of bubble spinning. Background Art

[0002] The nanofiber substrate can provide a good activity environment for cell proliferation, migration and differentiation. The pore structure of the fiber can exchange nutrients and information between cells, promoting tissue repair and regeneration. Electrospinning technology is the most effective method for preparing nanofibers of different sizes. Electrospinning technology is a common method for preparing small-caliber tissue engineering scaffolds. It can control the microscopic morphology of the scaffold by controlling the orientation of the fibers. However, since electrospinning requires the use of high-voltage power, it has certain potential dangers. He Jihuan and other researchers pointed out in "Bubble Spinning Technology and Industrial Production of Nanofibers" that from the perspective of environmental protection and cost, the airflow field bubble spinning method is safer and more convenient, but when the existing bubble spinning device is spinning, the bubble rupture will affect each other, resulting in low spinning efficiency and high spinning cost.

[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figures 1 to 4 The bubble spinning device shown in one embodiment of the present invention includes a liquid storage device 1, a plurality of foaming devices 2, an air supply device 4, a liquid supply device 5 and a receiving device 3. The liquid storage device 1 has a receiving chamber 11. A plurality of foaming devices 2 are arranged on the side wall of the liquid storage device 1, each foaming device 2 includes a shell 21 installed on the liquid storage device 1 and an injection mechanism 22 arranged in the shell 21, a liquid chamber 23 is formed in the shell 21, a switch 24 is arranged between the foaming device 2 and the receiving chamber 11 to connect or disconnect the foaming device 2 and the receiving chamber 11, and an injection hole 25 is opened on one end of the shell 21 away from the liquid storage device 1. The air supply device 4 is connected to the injection mechanism 22. The liquid supply device 5 supplies liquid to the liquid storage device 1. The receiving device 3 is arranged around the outer side of the side wall of the liquid storage device 1. During spinning, the gas supply device 4 delivers gas to the jet mechanism 22 and forms bubbles in the liquid chamber 23. Under the action of the airflow field, the bubbles ejected by the jet mechanism 22 are blown apart by the airflow at the jet hole 25 to form a jet, which is then drawn into filaments under the action of the airflow field and received by the receiving device 3. By arranging the housing 21 outside the jet mechanism 22, the bubbles generated by each jet mechanism 22 do not affect each other, so as to improve the spinning efficiency. A switch 24 is arranged between the foaming device 2 and the accommodating chamber 11, so as to control the number of foaming devices 2 involved in spinning according to actual needs, so as to save resources and further improve the spinning efficiency.

[0027] In this embodiment, the liquid storage device 1 has a barrel body 12 surrounding a receiving chamber 11. The barrel body 12 is cylindrical and has a plurality of openings (not shown). The plurality of foaming devices 2 are installed on the plurality of openings in a one-to-one arrangement. The switch 24 can be a valve or a partition. When the bubble spinning device is spinning, the number of the foaming devices 2 participating in the spinning is first determined according to actual needs, and the switches 24 on the foaming devices 2 not participating in the spinning are closed (e.g., Figure 3), so that the spinning liquid (not shown) in the liquid storage device 1 cannot enter the liquid cavity 23, and the gas supply device 4 cannot deliver gas to the jet mechanism 22, so that the jet mechanism 22 cannot generate bubbles in the liquid cavity 23, that is, the foaming device 2 does not participate in spinning. The foaming device 2 is conical, and the injection hole 25 is located at the top of the cone. The conical foaming device 2 makes the jet injection direction generated after the bubble bursts more accurate. Of course, in other embodiments, the foaming device 2 can also be set to other shapes, specifically a prism or a pyramid, which will not be exemplified here.

[0028] The air supply device 4 includes an air jet conduit 41 disposed in the liquid storage device 1 and an air supply device 42 connected to one end of the air jet conduit 41, and the air jet conduit 41 is connected to the air jet mechanism 22. Specifically, the air jet conduit 41 includes a main pipe 411 and a plurality of branch pipes 412 protruding from the main pipe 411, and the plurality of branch pipes 412 are connected one-to-one with the plurality of air jet mechanisms 22. The branch pipes 412 make it more convenient and tight to connect the air jet mechanism 22 with the main pipe 411, and also facilitate subsequent maintenance. Only the branch pipes 412 that are not tightly connected need to be replaced, without replacing the entire air jet conduit 41, thereby reducing the subsequent maintenance cost. In other embodiments, the branch pipes 412 may not be provided, and the air jet mechanism 22 is directly connected to the main pipe 411.

[0029] In this embodiment, the jet duct 41 is arranged in a spiral along the central axis of the liquid storage device 1. The jet duct 41 is spirally arranged in the liquid storage device 1, and correspondingly, the foaming device 2 is also spirally arranged on the side wall of the liquid storage device 1, so that the bubble spinning device can disperse the spinning when in use, further reducing the mutual influence of different foaming devices 2 during spinning, improving the spinning efficiency, and at the same time making the jet duct 41 arranged in the same manner as the foaming device 2, reducing the production cost of the jet duct 41 and saving resources. Of course, in other embodiments, the jet duct 41 can also be set to other arrangements, specifically a horizontal arrangement, which is not given one by one here, and can be adjusted according to actual needs.

[0030] The number of foaming devices 2 corresponding to one circle of the jet duct 22 around the liquid storage device 1 is 1 to 36. Specifically, the outer circumference of the liquid storage device 1 is 360°, and one circle around the liquid storage device 1 is a cycle. In each cycle, adjacent foaming devices 2 are arranged on the side wall of the liquid storage device 1 at a certain angle. When the minimum spacing angle between adjacent foaming devices 2 is less than 10°, the jets generated by adjacent foaming devices 2 will affect each other. Therefore, the number of foaming devices 2 corresponding to one circle around the liquid storage device 1 is set to 36 at most. In this way, the minimum spacing angle of each foaming device 2 is set to 10°, so as to avoid mutual influence between adjacent foaming devices 2 and improve spinning efficiency. It should be noted that in this example, the number of cycles is set to 3 times. In other examples, the number of cycles can be adjusted according to the size of the spinning device and the actual spinning requirements.

[0031] The liquid storage device 1 and the receiving device 3 can rotate relative to each other. Specifically, the bubble spinning device is provided with a driving device (not shown), and the driving device drives the liquid storage device 1 to rotate in a first direction, or the driving device drives the receiving device 3 to rotate in a second direction, or the driving device synchronously drives the liquid storage device 1 to rotate in the first direction and drives the receiving device 3 to rotate in the second direction. Among them, the first direction refers to clockwise or counterclockwise rotation along the central axis of the liquid storage device 1, and the second direction is opposite to the first direction. When the liquid storage device 1 rotates clockwise along its central axis, the receiving device 3 rotates in different directions from the liquid storage device 1, which is beneficial to the drafting of the jet and the orderly arrangement of the fibers on the receiving device 3. When the liquid storage device 1 rotates, the jet conduit 41 and the liquid storage device 1 keep coaxial, equidirectional and equispeed rotation, so that the jet conduit 41 and the jet mechanism 22 remain in a relatively static state.

[0032] In this embodiment, the bubble spinning device further includes a movable bracket 7, which is disposed on the receiving device 3, and the movable bracket 7 is driven by an external force to rotate the receiving device 3 along the second direction. It should be noted that the movable bracket 7 can also control the receiving device 3 to move along its axial direction to facilitate finishing work before and after spinning.

[0033] The central axis of the liquid storage device 1 and the central axis of the receiving device 3 are located on the same axis. In this embodiment, the receiving device 3 is a cylinder arranged around the outer side of the side wall of the liquid storage device 1, and the distance from each part to the liquid storage device 1 is equal, so that the distance between each foaming device 2 and the receiving device 3 is equal, so that the receiving device 3 can uniformly receive the jet to achieve uniform spinning.

[0034] In this embodiment, the central axis of the foaming device 2 is perpendicular to the central axis of the liquid storage device 1, and the center point of the injection hole 25 is located on the central axis of the foaming device 2. Therefore, the bubbles generated by each jet mechanism 22 can directly and quickly reach the injection hole 25, avoiding the bubbles from being broken by the air flow field in the liquid cavity 23, thereby improving the spinning efficiency.

[0035] The specific operation process of the spinning device of this embodiment is as follows: before use, the number of foaming devices 2 required to be used is determined, and the switch 24 between the foaming device 2 involved in spinning and the accommodating chamber 11 is turned on, so that the spinning liquid in the accommodating chamber 11 enters the liquid chamber 23 of the foaming device 2 involved in spinning. When in use, the gas supply device 42 transports gas to the jet mechanism 22 through the jet duct 41, and bubbles are formed in the spinning liquid in the liquid chamber 23. The bubbles reach the injection hole 25 and burst to form a jet under the action of the airflow field. The jet continues to be drawn into filaments under the action of the airflow field and is received by the receiving device 3.

[0036] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.

[0037] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
