Description

Technical Field

[0001] This utility model relates to the technical field of knitted fabric accessories, specifically a moisture-proof structure for knitted fabric. Background Technology

[0002] Knitted fabric is a type of fabric formed by bending yarns into loops and interlocking them using knitting needles. The difference between knitted and woven fabrics lies in the form of the yarns within the fabric. Knitted fabrics are widely used in clothing fabrics and linings, home textiles, and other products, and are popular with consumers. After production and winding, knitted fabrics need to be stored in a moisture-proof environment, requiring the use of moisture-proof structures to achieve excellent moisture protection.

[0003] The utility model patent with the public license number CN 215400486 U discloses a moisture-proof structure for knitted fabric, including a knitted fabric roll. The fixed plate is provided with an elastic flip end that cooperates with the circumferential side of the knitted fabric roll. The inner wall of the elastic flip end cooperates with the circumferential side of the knitted fabric roll. Air is extracted from the sealed knitted fabric roll through the air extraction hole to reduce the internal air and prevent the knitted fabric roll from getting moldy and damp during storage and transportation.

[0004] However, its moisture-proof structure, after the air between the knitted fabric roll and the sealing sleeve is expelled, the air pressure inside the sealing sleeve will be lower than the external atmospheric pressure. This will cause the inner surface of the sealing sleeve to tightly wrap the outer side of the knitted fabric roll, and the sealing sleeve will exert greater pressure on the knitted fabric. If the knitted fabric is a wrinkle-prone material such as silk, the pressure generated by the sealing sleeve will cause wrinkles or creases in the silk knitted fabric, affecting its appearance. Therefore, its application range is relatively limited. Utility Model Content

[0005] The purpose of this invention is to provide a moisture-proof structure for knitted fabrics to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof structure for knitted fabric, comprising a winding drum, wherein the inner wall of the winding drum is provided with a plurality of first through holes in a ring shape from one side to the other side, the outer wall of the winding drum is wound with knitted fabric, the outer side of the knitted fabric is fitted with a sealing sleeve, both ends of the inner wall of the sealing sleeve are provided with circular plates, both ends of the outer wall of the sealing sleeve are tied with straps, one side of the inner wall of the circular plate is provided with an air replenishment component, the other side of the inner wall of the circular plate is fixedly connected with a horizontal pipe, a one-way valve is installed on the pipe of the horizontal pipe, an air extraction nozzle is fixedly connected to the outer end of the horizontal pipe, a circular groove seat is concentrically fixed to the inner surface of the circular plate, a rubber layer is fixedly connected to the inner wall of the circular groove seat, and the rubber layer abuts against the contact surface of the winding drum;

[0007] The air replenishment component includes a horizontal cylinder, a second through hole, a rubber ring, a first breathable plate, moisture-absorbing particles, a second breathable plate, a support rod, a knob, a socket, and a plug rod;

[0008] The outer wall of the horizontal cylinder is threadedly connected to the inner wall of a circular plate on one side. The inner wall of the horizontal cylinder has multiple annular second through holes. A rubber ring is fitted tightly against the outer side of each second through hole, and the rubber ring is fixedly connected to the contact surface of the circular plate. A first ventilated plate is provided on one side of each second through hole, and the first ventilated plate is fixedly connected to the inner wall of the horizontal cylinder. A second ventilated plate is provided on one side of the first ventilated plate, and the outer wall of the second ventilated plate is fixedly connected to the inner wall of the horizontal cylinder. Multiple moisture-absorbing particles are provided between the second ventilated plate and the first ventilated plate. Support rods are fixedly connected to both the upper and lower ends of one side surface of the second ventilated plate, and a knob is fixedly connected to one end of each support rod. Insertion holes are provided at both the upper and lower ends of one side surface of the horizontal cylinder, and insertion rods are inserted into the inner walls of the insertion holes.

[0009] Preferably, the outer wall of the circular plate is provided with an annular groove.

[0010] Preferably, a baffle is attached to the outer surface of the knob, a protruding nail is inserted into the top of the outer surface of the baffle, the protruding nail passes through the contact surface of the baffle and is fixedly connected to the contact surface of the knob, and a handle is fixedly connected to the bottom of the outer surface of the baffle.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the moisture-proof structure of this knitted fabric has the following advantages over traditional technology:

[0012] Through the cooperation between the winding drum, the first through hole, the knitted fabric, the sealing sleeve, the circular plate, the strap, the supplementary assembly, the horizontal tube, the one-way valve, the air extraction nozzle, the circular groove seat, and the rubber layer, when the knitted fabric is a wrinkle-prone knitted fabric, the operator needs to apply force to the knob to rotate the horizontal drum. The end of the second through hole separates from the inner wall of the rubber ring, and the second through hole is in a state of interconnection with the inside of the winding drum. At this time, outside air flows into the inside of the sealing sleeve. During this process, when the airflow passes through multiple moisture-absorbing particles, the moisture in the airflow can be absorbed by the moisture-absorbing particles, making the air injected into the inside of the sealing sleeve dry and without moisture. The air pressure inside the sealing sleeve is close to the outside air pressure. The sealing sleeve protects the internal knitted fabric without pressing it too hard, making it less likely to cause wrinkles or creases in the easily wrinkled knitted fabric. The scope of application is broadened, making it easier to promote and use. Attached Figure Description

An air-injection component 7 is provided on the inner wall of one circular plate 5, and a horizontal pipe 8 is fixedly connected to the inner wall of the other circular plate 5. A one-way valve 9, a diaphragm one-way valve, is installed on the horizontal pipe 8, allowing only outside air to flow into the interior of the horizontal drum 701 through the horizontal pipe 8. An air extraction nozzle 10 is fixedly connected to the outer end of the horizontal pipe 8. The air extraction nozzle 10 is internally connected to the horizontal tube 8, and the air extraction nozzle 10 can be connected to an external air extraction device. A circular groove seat 11 is concentrically fixed to the inner surface of the circular plate 5. A rubber layer 12 is fixed to the inner wall of the circular groove seat 11. The rubber layer 12 abuts against the contact surface of the winding drum 1. The air replenishment component 7 includes a horizontal cylinder 701, a second through hole 702, a rubber ring 703, a first vent plate 704, moisture-absorbing particles 705, a second vent plate 706, a support rod 707, a knob 708, an insertion hole 709, and an insertion rod 710. The outer wall of the horizontal cylinder 701 is threadedly connected to the inner wall of one side of the circular plate 5. The inner wall of the horizontal cylinder 701 has multiple second through holes 702 in an annular shape. The second through holes 702 are internally connected to the horizontal cylinder 701, and the outer side of the second through holes 702 abuts against a... A rubber ring 703, made of rubber, possesses a certain degree of flexibility. The rubber ring 703 abuts against the outer wall of the horizontal cylinder 701 and is fixedly connected to the contact surface of the circular plate 5. A first vent plate 704 is provided on one side of the second through hole 702, and is fixedly connected to the inner wall of the horizontal cylinder 701. A second vent plate 706 is provided on one side of the first vent plate 704. Both the first and second vent plates 704 are made of PVC material with numerous vent holes on their surfaces. The outer wall of the second vent plate 706 is fixedly connected to the inner wall of the horizontal cylinder 701. Multiple moisture-absorbing particles 705 are provided between the second vent plate 706 and the first vent plate 704. The moisture-absorbing particles 705 are SAP resin water-absorbing particles capable of adsorbing moisture. The moisture in the airflow can be absorbed by the moisture-absorbing particles 7, which can also be other non-toxic, highly absorbent materials. Support rods 707 are fixed to both the upper and lower ends of one side surface of the second breathable plate 706. A knob 708 is fixed to one end of one side of the support rod 707. Insertion holes 709 are opened at both the upper and lower ends of one side surface of the horizontal cylinder 701. Insertion rods 710 are inserted into the inner walls of the insertion holes 709, and the outer walls of the insertion rods 710 abut against the inner walls of the insertion holes 709. The contact surfaces of the insertion rods 710 and the knob 708 are fixedly connected. An annular groove is opened on the outer wall of the circular plate 5. A baffle 13 is attached to the outer surface of the knob. The baffle 13 is made of rubber and has a certain degree of flexibility. A protruding nail 14 is inserted into the top of the outer surface of the baffle 13, and the protruding nail 14 penetrates the baffle 13 and is fixedly connected to the contact surface of the knob 708.A handle 15 is fixedly attached to the bottom of the outer surface of the baffle 13. The handle 15 allows the operator to apply force to the baffle 13. The baffle 13 can block the outside of the knob 708, thus blocking the air inlet of the knob 708 when it is not necessary to add air into the winding drum 1, facilitating the long-term and effective use of the moisture-absorbing particles 705.

[0020] In the process of using the moisture-proof structure for knitted fabric, firstly, the two round groove seats 11 are respectively fitted onto the two ends of the take-up drum 1, so that the rubber layer 12 on the inner wall of the round groove seat 11 is pressed against the contact surface of the take-up drum 1. Next, the sealing sleeve 4 is fitted onto the outside of the knitted fabric 3, and the sealing sleeve 4 is tied to the upper part of the outer wall of the round plate 5 using the strap 6. Then, the air extraction device 10 is used to extract the air from the inside of the sealing sleeve 4, thus completing the sealing of the knitted fabric 3 to prevent it from getting damp and mildewed. If the knitted fabric 3 is a wrinkle-prone knitted fabric, the operator needs to apply force to the knob 708 to rotate the horizontal cylinder 701. Due to the threaded connection between the horizontal cylinder 701 and the inner wall of the round plate 5, the horizontal cylinder 701 can be moved towards the knitted fabric 3. The end of the second through hole 702 is connected to... The inner wall of the rubber ring 703 is separated, and the second through hole 702 is in a state of mutual communication with the inside of the winding drum 1. At this time, outside air flows into the inside of the sealing sleeve 4 through the knob 708, the second vent plate 706, multiple moisture-absorbing particles 705, the first vent plate 704, the second through hole 702, the first through hole 2, and the knitted fabric 3. During this process, when the airflow passes through multiple moisture-absorbing particles 705, the moisture in the airflow can be absorbed by the moisture-absorbing particles 705, so that the air injected into the sealing sleeve 4 is dry and moisture-free. The air pressure inside the sealing sleeve 4 is close to the outside air pressure. The sealing sleeve 4 protects the internal knitted fabric 3 without pressing it too hard, and it is not easy to cause wrinkles or creases in the easily wrinkled knitted fabric 3. The application range is broadened and it is easy to promote its use.
