Description

Technical Field

[0001] This utility model relates to the field of high-voltage electrospinning machine technology, specifically a high-voltage electrospinning machine with adjustable spinning angle. Background Technology

[0002] The high-voltage electrospinning device consists of a base, a jet nozzle, a high-voltage power supply, and a receiving screen. The basic principle is to apply an electrostatic field of tens of thousands of volts between the jetting device and the receiving device, forming a jet from the cone end of the spinning solution, which is stretched in the electric field and finally forms non-woven nanofibers on the receiving device.

[0003] Currently, the jetting device in high-voltage electrospinning equipment is usually installed directly on a desktop. This installation method results in the spinning liquid jetted by the jetting device not being evenly distributed on the upper part of the receiving screen, thus affecting the uniformity of the nanofiber distribution on the receiving screen.

[0004] Therefore, we propose a high-voltage electrospinning machine with adjustable spinning angle to solve the problems mentioned above. Utility Model Content

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.

[0023] Example 1: Please refer to Figures 1-3A high-voltage electrostatic spinning machine with adjustable spinning angle includes a support platform 1 and support legs 2 fixedly installed at the four corners of the lower end of the support platform 1. A high-voltage power supply assembly 3 is installed in the middle of one side of the upper end of the support platform 1. A high-voltage power source 4 is connected to the wiring port of the high-voltage power supply assembly 3. A receiving assembly 5 is installed at one end of the upper end of the support platform 1. A spraying assembly 6 is installed at the other end of the upper end of the support platform 1 through a reciprocating assembly 7. The reciprocating assembly 7 is set to drive the spraying assembly 6 to reciprocate, thereby spraying the solution from the spraying assembly 6 evenly onto the outer surface of the receiving assembly 5.

[0024] After the needle of the injection syringe 67 is connected to the high-voltage power supply 4 of the high-voltage power supply assembly 3, the polymer solution becomes charged with high-voltage static electricity and is squeezed out of the syringe under the action of electric field force.

[0025] High-voltage power supply component 3 is a current technology and is not limited here. It can be installed by purchasing commercially available finished products, such as the TRC2025 series push high-voltage power supply.

[0026] The reciprocating assembly 7 includes a drive mechanism 71 and a mounting mechanism 72 installed at the upper middle part of the drive mechanism 71. A clamping mechanism 73 is fixedly installed at one end of the outer wall of the mounting mechanism 72. The mounting mechanism 72 is configured to be suitable for installing the spray assembly 6. The clamping mechanism 73 is configured to improve the stability of the connection between the high-voltage power source 4 and the nozzle of the spray assembly 6.

[0027] The receiving component 5 includes a support base 51 and a first rotating ring 52 installed on the lower end of one side of the outer wall of the support base 51.

[0028] A transmission belt 53 is wound around the outer surface of the first rotating ring 52. A second rotating ring 54 is provided at one end of the transmission belt 53. A receiving roller 55 is installed in the middle of the second rotating ring 54 via a coupling. The first rotating ring 52 and the transmission belt 53 are driven to rotate by a motor, so that the transmission belt 53 drives the receiving roller 55 installed in the middle of the second rotating ring 54 via the coupling to rotate together, thereby realizing the rotation setting of the receiving roller 55.

[0029] The spray assembly 6 includes a mounting base 61 and a connecting shaft 62 disposed on one side of the outer wall of the mounting base 61. A second motor (not shown in the figure) is mounted on one end of the connecting shaft 62. The second motor (not shown in the figure) is installed in the inner cavity of the mounting base 61. A first gear 63 is connected to one end of the connecting shaft 62. The first gear 63 is meshed with a second gear 64. A threaded rod 65 is provided in the middle of one end of the second gear 64. A corresponding drive block 66 is threadedly connected to the outer surface of the threaded rod 65. A spray syringe 67 is connected to one end of the corresponding drive block 66.

[0030] The second motor drives the connecting shaft 62 to rotate, which in turn drives the first gear 63 to rotate. The first gear 63 meshes with and drives the second gear 64 to rotate, which in turn drives the threaded rod 65 to rotate. This causes the corresponding drive block 66, which is threaded onto the threaded rod 65, to move. The second motor rotates in both directions to achieve the reciprocating motion of the corresponding drive block 66, thereby pushing the spray syringe 67 to spray the solution. The spray syringe 67 is fixedly mounted on the upper side of the mounting base 61.

[0031] The drive mechanism 71 includes a fixed bracket 711 and guide rods 712 fixedly installed on both sides of one end of the fixed bracket 711. An auxiliary frame 713 is fixedly installed on one end of the guide rod 712. The guide rod 712 is movably installed in the inner cavity of the circular groove 718. The guide rod 712 is arranged to guide the sliding base 716 in a sliding manner.

[0032] A forward and reverse motor 714 is fixedly installed at the other end of the fixed bracket 711. A lead screw 715 is installed at the output end of the forward and reverse motor 714. A sliding base 716 is threadedly connected to the outer surface of the lead screw 715. A threaded groove 717 is opened in the middle of the lower end of the sliding base 716. Circular grooves 718 are opened on both sides of the lower end of the sliding base 716. The threaded groove 717 is threadedly connected to the outer surface of the lead screw 715.

[0033] The mounting mechanism 72 includes a concave block 721 and a circular threaded groove 722 formed in the middle of one side of the inner wall of the concave block 721. A first screw 723 is threadedly connected to the inner cavity of the circular threaded groove 722. A first bearing 724 is installed at one end of the first screw 723, and a clamping plate 725 is installed at one end of the first bearing 724.

[0034] Sliding blocks 726 are respectively provided on both sides of the lower end of the clamping plate 725. The sliding blocks 726 are slidably installed in the inner cavity of the sliding grooves 727 opened on both sides of the upper end of the concave block 721. The sliding blocks 726 are provided to improve the stability of the movement of the clamping plate 725.

[0035] In this embodiment: the mounting base 61 is placed on the upper end of the concave block 721, so that the side wall of the mounting base 61 is placed against the inner wall of the concave block 721. By rotating the first screw 723 threaded in the inner cavity of the circular screw groove 722, the first screw 723 drives the first bearing 724 and the clamping plate 725 to move, so that the clamping plate 725 presses and fixes the inner wall of the mounting base 61 to the upper end of the concave block 721. By starting the forward and reverse motor 714, the lead screw 715 is driven to rotate, so that the sliding base 716 threaded on the outer surface of the lead screw 715 drives the concave block 721 and the spraying assembly 6 to move together, so that the spraying assembly 6 reciprocates at the upper end of the drive mechanism 71, thereby moving the spraying position of the spraying assembly 6.

[0036] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 4-5 The clamping mechanism 73 includes a corner support rod 731 and a hollow cylinder 732 fixedly installed on one side of the upper end of the corner support rod 731. A second screw 733 is threadedly connected to the middle of the upper end of the outer wall of the hollow cylinder 732. A second bearing 734 is installed at one end of the second screw 733, and a semi-circular clamping plate 735 is installed at one end of the second bearing 734. The high-voltage power source 4 is movably installed in the inner cavity of the hollow cylinder 732, and the high-voltage power source 4 is limited and fixed by the semi-circular clamping plate 735.

[0037] In this embodiment: When the spray assembly 6 is working, the needle position of the spray syringe 67 is connected to the high-voltage power source 4. Since the spray assembly 6 moves under the drive of the drive mechanism 71, in order to improve the connection stability between the high-voltage power source 4 and the needle position of the spray syringe 67, the high-voltage power source 4 is passed through the inner cavity of the hollow cylinder 732. By rotating the second screw 733, which is threaded to one side of the inner wall of the hollow cylinder 732, the second bearing 734 and the semi-circular clamp 735 are moved, so that the semi-circular clamp 735 presses the high-voltage power source 4 against one side of the inner wall of the hollow cylinder 732, thereby improving the stability of the connection between the upper end of the high-voltage power source 4 and the needle of the spray syringe 67.

[0038] Working principle: The mounting base 61 is placed on the upper end of the concave block 721, so that the side wall of the mounting base 61 is placed against the inner wall of the concave block 721. By rotating the first screw 723, which is threaded into the inner cavity of the circular screw groove 722, the first screw 723 drives the first bearing 724 and the clamping plate 725 to move, so that the clamping plate 725 presses and fixes the inner wall of the mounting base 61 to the upper end of the concave block 721. By starting the forward and reverse motor 714, the lead screw 715 is driven to rotate, so that the sliding base 71, which is threaded onto the outer surface of the lead screw 715, moves. The 6 drives the concave block 721 and the spray assembly 6 to move together, so that the spray assembly 6 reciprocates at the upper end of the drive mechanism 71, thereby moving the spray position of the spray assembly 6 to spray. The needle of the spray syringe 67 is connected to a high-voltage power source 4. The high-voltage power source 4 is passed through the inner cavity of the hollow cylinder 732. By rotating the second screw 733, which is threaded to one side of the inner wall of the hollow cylinder 732, the second bearing 734 and the semi-circular clamp 735 are moved, so that the semi-circular clamp 735 presses the high-voltage power source 4 against one side of the inner wall of the hollow cylinder 732.
