[0031] Embodiment 1: Figure 1 As shown, a spinning push-injection device comprises: a push plate 1, a first fixing member 2, a second fixing member 3 and a third fixing member 4; the push plate 1 is connected to the first fixing member 2. The push plate 1 can be a rectangular flat plate made of stainless steel with sufficient strength and wear resistance. The first fixing member 2 can be an annular clamp with a groove matching the outer diameter of the push rod inside. The material of the clamp can be rubber or silicone to increase the friction with the push rod to prevent sliding during the push-injection process. The push plate 1 can be connected to the first fixing member 2 by bonding or by screws. A threaded hole is reserved on the push plate 1, and a corresponding threaded hole is also designed on the first fixing member 2. The screw passes through the threaded hole of the push plate 1 and is screwed into the threaded hole on the first fixing member 2 to achieve a tight connection between the two. This connection method is simple and convenient, and is easy to disassemble and repair.

[0032] The first fixing member 2 is used to fix the push rod of the syringe; the second fixing member 3 is connected to the push plate 1 through the sliding member 5, and the second fixing member 3 is used to fix the syringe barrel of the syringe. The second fixing member 3 can be a plate-like structure with a fixing hole, the size and shape of the fixing hole match the outer diameter of the syringe, and the syringe is inserted into the fixing hole, and the fixing hole plays a role in fixing the syringe. The sliding member 5 can be a structure of a slide rail and a slider, the slide rail is fixed on the second fixing member 3, and the slider is connected to the push plate 1. The slider can move freely on the slide rail, and the push plate 1 is pushed by controlling the movement of the slider.

[0033] The first fixing member 2 and the second fixing member 3 are located on the same horizontal line, which can ensure that the push rod and the syringe of the syringe always remain parallel and stable during the injection process. This stability is crucial for the uniform advancement of the spinning solution and can prevent the unstable flow or blockage of the spinning solution caused by the angle deviation between the push rod and the syringe.

[0034] The third fixing member 4 is connected to the second fixing member 3, and the third fixing member 4 is used to fix the liquid outlet of the syringe. The third fixing member 4 can be an annular structure with a clamping device, and the clamping device can be an adjustable clamp or a clamp. The inner diameter of the clamping device matches the outer diameter of the liquid outlet, and the liquid outlets of different diameters can be fixed by adjusting the clamping device.

[0035] In this embodiment, the push plate 1 is pushed forward along the sliding member 5. The movement of the push plate 1 drives the first fixing member 2 and the push rod of the syringe forward, thereby pushing the spinning solution out of the syringe. Since the first fixing member 2 and the second fixing member 3 are located on the same horizontal line, the push rod and the syringe always remain parallel and stable during the push injection process, ensuring that the spinning solution is pushed evenly. The spinning solution passes through the liquid outlet end of the syringe, and the liquid outlet end of the syringe is fixed by the third fixing member 4, and the liquid outlet end of the syringe does not shake or deviate during the push injection process.

[0036] Embodiment 2: Considering that the spinning solution is injected into the syringe before the injection begins, the end of the push rod is located outside the syringe and away from the syringe. Under the action of gravity, the end of the push rod is tilted downward. When the push plate of the injection device touches the push rod, an uneven contact force between the push rod and the inner wall of the syringe will be caused. This uneven contact force may cause the push rod to shake during the first push, thereby affecting the uniformity and stability of the spinning solution push out.

[0037] In order to solve the above problem, in a possible implementation manner, Figure 2As shown, the first fixing member 2 includes a ring sleeve 201, which is connected to the side wall of the push plate 1 and is used to fix the push rod of the syringe; the ring sleeve 201 can be made of elastic material, such as rubber or silicone, and the ring sleeve 201 is an annular structure, and its inner diameter is slightly smaller than the maximum outer diameter of the push rod. The wall thickness of the ring sleeve should be sufficient to provide sufficient elasticity and wrapping force. When the end of the push rod is inserted into the ring sleeve 201, the ring sleeve will automatically wrap the push rod to ensure that the push rod can be firmly fixed in the ring sleeve 201. The ring sleeve 201 can support the bottom of the syringe push rod to prevent the syringe push rod from tilting downward under the action of gravity. The ring sleeve 201 can be bonded to the side wall of the push plate 1 by an adhesive, or it can be fixedly connected by screws. For example, a small hole is opened on the side wall of the push plate 1 for passing the screw. A small hole is also opened on the outer edge of the ring sleeve 201 to align with the hole on the push plate 1. A small screw is used to pass through the two holes to fix the ring sleeve 201 on the side wall of the push plate 1.

[0038] The second fixing member 3 includes a fixing plate 301, and a fixing hole 302 is provided on the fixing plate 301, and the fixing hole 302 is used to fix the middle part of the syringe; the fixing plate 301 is a solid flat plate structure, which is designed to provide a stable support and fixing point. A fixing hole 302 is provided on the fixing plate 301, and the shape and size of the fixing hole 302 match the middle part of the syringe, which can ensure that the syringe is firmly fixed in the fixing hole 302. When fixing the syringe on the fixing plate 301, first align the middle part of the syringe with the fixing hole 302, and then gently insert the syringe into the hole. Since the fixing hole 302 matches the size of the syringe, the syringe will be firmly fixed in the fixing hole 302 and will not shake or deviate during the injection process. In a possible embodiment, an elastic pad is provided in the fixing hole 302, and the elastic pad can fill the gap between the fixing hole 302 and the syringe, further improving the fixing effect of the fixing hole 302.

[0039] The third fixing member 4 includes a first fixing ring 401, which is connected to the fixing plate 301 via a connecting member 6, and is used to fix the liquid outlet of the syringe; the first fixing ring 401 is connected to the fixing plate 301, and the connecting member 6 is used. The connecting member 6 can be a screw, a bolt or other fastener, which is used to fix the first fixing ring 401 and the fixing plate 301 together. This connection method is simple and reliable, and can ensure that the first fixing ring 401 maintains a stable position during the injection process, thereby ensuring that the liquid outlet of the syringe will not shake or deviate.

[0040] The centers of the ring sleeve 201 , the fixing hole 302 and the first fixing ring 401 are located on the same horizontal line.

[0041] In this embodiment, the ring sleeve 201 wraps around the end of the push rod to ensure that the push rod can be firmly fixed in the ring sleeve 201. The ring sleeve 201 supports the bottom of the push rod to prevent the push rod from tilting downward under the action of gravity. During the push injection process, since the centers of the ring sleeve 201, the fixing hole 302 and the first fixing ring 401 are located on the same horizontal line, when the centers of the ring sleeve 201, the fixing hole 302 and the first fixing ring 401 are located on the same horizontal line, the push rod, the middle of the syringe and the center of the liquid outlet are all on the same vertical line. This alignment method can ensure that during the push injection process, the push rod moves in a straight line along the axis of the syringe, avoiding any lateral deviation or shaking. The stability and parallelism of the push rod, the syringe and the liquid outlet during the push injection process are ensured, and the uniformity and stability of the spinning solution are further improved.

[0042] Embodiment 3: Considering the different sizes of the end of the push rod, in order to provide stable support for the ends of the push rods of different sizes, in a possible implementation manner, Figure 3 As shown, the ring sleeve 201 includes a plurality of sub-ring sleeves, the plurality of sub-ring sleeves are co-centered, and the radius of each sub-ring sleeve is different. The sub-ring sleeve is made of elastic material, and the sub-ring sleeve can be designed into a nested structure, that is, a sub-ring sleeve can be inserted into another sub-ring sleeve inside, and can also be pulled out from another sub-ring sleeve. In this way, push rods of different sizes can select different numbers of sub-ring sleeves for nesting and use.

[0043] In this embodiment, a suitable sub-ring is selected for use according to the actual size of the push rod end. Since the radius of each sub-ring is different, it can adapt to push rod ends of different diameters. By inserting the end of the push rod into the suitable sub-ring, the ring will automatically wrap around the push rod, ensuring that the push rod is firmly fixed in the ring.

[0044] Since the ring sleeve 201 provides a stable support, the push rod will no longer tilt downward under the action of gravity. This ensures that when the push plate 1 starts to push the push rod, the push rod is in uniform contact with the inner wall of the injection barrel, thereby avoiding shaking. This design not only improves the uniformity and stability of the spinning solution push, but also enhances the flexibility and applicability of the push injection device.

[0045] Embodiment 4: In order to further improve the stability of the syringe during the push injection process, Figure 4 As shown, a second fixing ring 402 is disposed inside the first fixing ring 401, and the second fixing ring 402 is used to fix the needle of the syringe. Through the fixation of the second fixing ring 402, the needle is not easy to shake or deviate from the predetermined position during the push injection process, thereby improving the accuracy and stability of the overall push injection.

[0046] Embodiment 5: Figure 5As shown, considering that the solution at the syringe needle is easy to drip into the experimental box, the connector 6 includes a connecting portion 601 and an extension portion 602, one end of the connecting portion 601 is connected to the bottom of the first fixing ring 401, the other end of the connecting portion 601 is connected to the bottom of the fixing plate 301, one end of the extension portion 602 is connected to the connecting portion 601, and the other end of the extension portion 602 is located below the syringe needle. The connector 6 can be a connecting plate, the connecting portion 601 of the connecting plate is connected to the first fixing ring 401 and the fixing plate 301, the extension portion 602 of the connecting plate is located below the syringe needle, if the spinning solution at the needle drops, the extension portion 602 of the connecting plate can receive the dropped spinning solution.

[0047] Embodiment 6: In a possible implementation manner, Figure 6 As shown, it also includes: a driving member 7, the output end of the driving member 7 is connected to the push plate 1, and the driving member 7 is used to drive the push plate 1 to move toward the second fixed member 3. Wherein, the driving member 7 can be a motor. The driving member 7 includes a driving device 701, a baffle 702, a first gear 703, a second gear 704 and a third gear 705; the driving device 701 is arranged on the baffle 702, the output end of the driving device 701 passes through the baffle 702 and is connected to the first gear 703, and the first gear 703 is respectively engaged with the second gear 704 and the third gear 705; the sliding member 5 includes a first screw rod 501 and a second screw rod 502, one end of the first screw rod 501 is rotatably connected to the second fixed member 3, and the other end of the first screw rod 501 passes through the push plate 1 and is fixedly connected to the second gear 704; one end of the second screw rod 502 is rotatably connected to the second fixed member 3, and the other end of the second screw rod 502 passes through the push plate 1 and is fixedly connected to the third gear 705.

[0048] In this embodiment, a driving device 701 (such as a motor) is mounted on a baffle 702. The output end of the driving device 701 is connected to the first gear 703 through the baffle 702. When the driving device 701 is started, it drives the first gear 703 to rotate. The first gear 703 is meshed with the second gear 704 and the third gear 705 at the same time. Therefore, when the first gear 703 rotates, it drives the second gear 704 and the third gear 705 to rotate synchronously. The device includes two screw rods, namely a first screw rod 501 and a second screw rod 502. One end of the first screw rod 501 is rotatably connected to the second fixing member 3, and the other end is fixedly connected to the second gear 704 through the push plate 1. This means that when the second gear 704 rotates, it drives the first screw rod 501 to rotate. Similarly, one end of the second screw rod 502 is rotatably connected to the second fixing member 3, and the other end is fixedly connected to the third gear 705 through the push plate 1. Therefore, when the third gear 705 rotates, it drives the second screw rod 502 to rotate. Since the first screw rod 501 and the second screw rod 502 are both threadedly connected to the push plate 1, when the two screw rods rotate, they work together to push the push plate 1 toward the second fixing member 3. This design can ensure that the movement of the push plate 1 is smooth and accurate. By controlling the start, stop and rotation direction of the driving device 701, the moving speed and position of the push plate 1 can be accurately controlled, thereby achieving accurate control of the injection process.

[0049] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
