Description

Technical Field

[0001] The present application relates to the technical field of fiber stretching and forming equipment, and in particular to a silk fibroin fiber production stretching and forming equipment. Background Art

[0002] Silk fibroin fiber is silk. In the process of its production and processing, in order to show its high strength, high modulus and high orientation, it is often necessary to stretch it with a certain draft ratio to meet the use requirements in actual production and life.

[0003] However, when the existing stretching and forming equipment is stretching the silk fibroin fiber, the broken silk and the hairy silk caused by various factors are very easy to be entangled in the stretching roller, and the effective stretching radius of the stretching roller is increased invisibly during the continuous winding process, thereby increasing the stretching pressure of the stretching roller on the silk fibroin fiber, making the uniformity and stability of the stretching and forming of the silk fibroin fiber poor, and even causing the phenomenon of breaking;

[0004] Moreover, as the broken and fuzzy filaments are entangled in the stretching rollers, when the silk fibroin fibers are heated and insulated by the stretching rollers, the heat is difficult to transfer due to the obstruction of the broken and fuzzy filaments, which causes the temperature of the silk fibroin fibers to become lower accordingly, further affecting the uniformity and stability of the stretching and molding of the silk fibroin fibers by the stretching and molding equipment.

[0005] Therefore, there is an urgent need for a stretching and molding device for silk fibroin fibers to solve the defects of the above-mentioned existing stretching and molding devices during actual use. Summary of the invention

[0006] The present application proposes a silk fibroin fiber production stretching and forming equipment, which has the advantages of effectively avoiding the phenomenon of broken wires and entanglement of hairy wires in the stretching rollers thereon, so that the uniformity and stability of the stretching and forming of the silk fibroin fibers are higher, and is used to solve the problem that when the existing stretching and forming equipment is performing a stretching operation on the silk fibroin fibers, the broken wires and hairy wires caused by various factors are very likely to be entangled in the stretching rollers, and the effective stretching radius of the stretching rollers is invisibly increased during the continuous winding process, thereby increasing the stretching pressure of the stretching rollers on the silk fibroin fibers, making the uniformity and stability of the stretching and forming of the silk fibroin fibers poor, and even causing the fibers to break.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a silk fibroin fiber production stretching and forming equipment, including a support plate that can be fixedly installed on the stretching and forming equipment by bolts, a through hole is opened on the periphery of the front side of the support plate, and a plurality of groups of support plates can be assembled together by screws according to actual use needs to cooperate in use, so as to simultaneously stretch and form a plurality of groups of silk fibroin fibers, and a group of end covers are respectively provided on the front and rear sides of the support plate, a stretching roller is connected to the top of one side of the inner cavity of the support plate and between the two groups of end covers by an axis, and a stretching roller is fixedly installed at the bottom of the other side of the inner cavity of the support plate and between the two groups of end covers. There is a driving wheel group, and a transmission belt is connected between the stretching roller and the driving wheel group, so that when the driving wheel group is started, the transmission belt can be driven to rotate. One end of the stretching roller extends to the outside of the supporting disk, and the outer side surface of the transmission belt contacts the outer surface of the silk fibroin fiber, so that the silk fibroin fiber can be squeezed by the stretching roller and stretched and deformed. A negative pressure wheel group with an outer surface in contact with the transmission belt is provided in the middle of the other side of the inner cavity of the supporting disk and between the two groups of end covers. One end of the negative pressure wheel group is connected to a negative pressure pump, so that negative pressure can be formed inside it to absorb broken silk and hairy silk carried on the outer surface of the transmission belt.

[0008] Furthermore, the negative pressure wheel group includes a hollow shaft tube arranged in the middle of the other side of the inner cavity of the support plate through two groups of end covers, one end of the hollow shaft tube is connected to the negative pressure pump, a ring is fixedly sleeved in the middle of the outer surface of the hollow shaft tube, and a groove is provided on one side of the outer surface of the ring, a waist-shaped through groove connected to the inner cavity of the hollow shaft tube is provided inside the groove, a retaining ring is movably sleeved on the outer surface of the waist-shaped through groove, and a plurality of groups of connecting holes arranged in a ring array and connected to its outer surface and inner wall are provided inside the retaining ring, when the retaining ring rotates with the rotation of the transmission belt, only the connecting holes that rotate and move to the groove position can connect to the hollow shaft tube and generate negative pressure.

[0009] Furthermore, the groove is located above the contact point between the negative pressure wheel group and the transmission belt, so that the broken wires and hairy wires carried by the transmission belt can be adsorbed and removed before the transmission belt contacts the negative pressure wheel group, so as to effectively prevent them from adhering to the outer surface of the retaining ring and causing the connecting holes thereon to be blocked, and the outer surface of the retaining ring is in compression contact with the outer side surface of the transmission belt, causing the transmission belt to deform.

[0010] Furthermore, an annular groove is provided on the outer surface of the stretching roller, and during the transmission extrusion process, the transmission belt is deformed to match it, so that the silk fibroin fiber can be movably clamped in the annular groove to prevent it from swinging left and right during the stretching and forming process.

[0011] Furthermore, the driving wheel group includes an electric spindle whose two ends are movably connected to the two sets of end covers respectively, and an electric heating ring is fixedly connected to the middle of the outer surface of the electric spindle, and is in friction contact with the inner side of the transmission belt through the electric heating ring. Therefore, while providing rotational power for the transmission belt, the electric heating ring can be used to heat the transmission belt so that the silk protein fiber can be stretched within a certain temperature range.

[0012] Furthermore, the electric spindle is located on a vertical line of a contact point between the silk fibroin fiber and the stretching roller, and the stretching roller and the electric spindle are respectively located on both sides of the center of the support disk.

[0013] Furthermore, the line connecting the negative pressure wheel group and the center of the stretching roller is perpendicular to the line connecting the stretching roller and the center of the electric spindle. Therefore, the setting of the positions of the stretching roller, the negative pressure wheel group and the electric spindle can effectively improve the stability and reliability of the stretching forming equipment during operation.

[0014] The beneficial effects of the present invention are as follows:

[0015] The present application provides a silk fibroin fiber production stretching and molding equipment. Regarding the arrangement of the stretching roller, the driving wheel group and the negative pressure wheel group, the negative pressure wheel group can be used to absorb and remove the broken filaments and hairy filaments carried by the silk fibroin fiber, thereby effectively avoiding the problem of the entanglement of the broken filaments and hairy filaments on the outer surface of the stretching roller. The electric heating ring in the electric spindle is used to heat and insulate the transmission belt, so that the silk fibroin fiber can always be stretched within a certain range, resulting in higher uniformity and stability of the silk fibroin fiber stretching and molding equipment.
