[0002] A cotton filling machine is a mechanical device used in the filling process, primarily in the textile and packaging industries, especially in clothing, home textiles, toys, and bedding. Its main function is to evenly fill the interior of products with cotton or other filling materials (such as down, foam, etc.) to improve comfort, warmth, or appearance. Automated filling reduces reliance on manual labor and minimizes human error. It is not limited to clothing and bedding but can also be used to fill toys, sofas, and other upholstered furniture. Besides cotton, cotton filling machines can process various other filling materials, including synthetic fibers, down, and sponge particles. Cotton filling machines are an indispensable piece of equipment in modern production, helping to improve production efficiency and product quality.
[0003] Conventional small cotton filling machines are small in size and can only fill small textiles. During the filling process, they are prone to clogging, which prevents the machine from working properly and requires internal repairs. Repeated clogging repairs can damage the equipment. Therefore, a small cotton filling machine with anti-clogging function and increased filling efficiency is designed to solve the above problems. Utility Model Content

It solves the problems of conventional small cotton filling machines, which are small in size and can only fill small textiles. During the filling process, they are prone to clogging, which prevents the cotton filling machine from working properly and requires internal maintenance. Furthermore, repeated clogging and maintenance can damage the equipment.
[0006] (II) Technical Solution
[0007] To achieve the aforementioned anti-clogging function and increase filling efficiency, this utility model provides the following technical solution: A small cotton filling machine includes a base plate and support legs located on the underside of the base plate. A machine housing is located on the upper side of the base plate. A protective cover is located on the top of the machine housing, and a cotton conveying port is located on the upper side of the protective cover. A cotton conveying hood is fixedly installed on the inner wall of the machine housing, and a conveying spiral blade is installed inside the cotton conveying hood. A tumbling mechanism is installed below the spiral blade shaft and is located at the bottom of the machine housing. An air pump and a filling pipe are respectively installed on both sides of the machine housing, and the output end of the air pump and the interior of the filling pipe are connected to the tumbling mechanism. Cotton is fed into the machine housing through the cotton conveying port and is located inside the cotton conveying hood. The spiral blade shaft inside the cotton conveying hood conveys the cotton inside, causing it to fall to the bottom of the machine housing. The tumbling mechanism tumbles the cotton to prevent it from clogging the internal channels of the machine housing during filling. The air pump inflates the tumbling mechanism and the surrounding cotton, allowing the cotton to be filled into the textile through the filling pipe.
[0008] Preferably, the tumbling mechanism includes a connecting shaft and a tumbling plate, with the connecting shaft mounted on the inner wall of the housing and the tumbling plate fixedly mounted on the outer side of the connecting shaft. The tumbling plate has multiple openings inside. There are at least three openings inside the tumbling plate, and the openings are triangular in shape. The triangular openings effectively prevent cotton from entering the interior, and also allow the strong airflow generated by the air pump to push the cotton into the filling tube.

Its output end is located inside the machine housing and is fixedly connected to the upper end of the spiral blade shaft. The conveying motor drives the spiral blade shaft to rotate inside the cotton conveying hood, thereby conveying the cotton inside the cotton conveying hood so that the cotton can fall to the bottom of the machine housing.
[0011] Preferably, the lower end of the cotton conveying hood is provided with a concentrating hood, which is fixedly installed on the inner wall of the machine housing. The lower end of the machine housing has a cotton feeding channel and an exhaust pipe, with the cotton feeding channel connected to the interior of the cotton filling pipe. The exhaust pipe is connected to the output end of the air pump, and a protective net is installed at the output end of the air pump. The connecting shaft and the turning plate are located inside the lower end of the concentrating hood. Cotton falls uniformly into the concentrating hood, which has a funnel-shaped upper end and a hollow cylindrical lower end. Grooves on both sides of the lower end of the concentrating hood are connected to the cotton feeding channel and the exhaust pipe. The air pump provides strong air to the exhaust pipe, which drives the cotton at the bottom of the concentrating hood into the cotton feeding channel. The cotton is then filled into the filling pipe, and the protective net at the air pump output end prevents cotton from entering the air pump. The connecting shaft and the turning plate are located at the lower end of the concentrating hood, at the cotton feeding channel.
[0012] Preferably, a lifting bracket is fixedly installed at one end of the base plate, and the lifting bracket is positioned below the filling tube. Small filling machines are generally manually operated, and conventional filling machines can only be operated by hand. The lifting bracket can assist the operator in filling the cotton; simply place the textile on the upper side of the lifting bracket for easy filling.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a small cotton filling machine with the following beneficial effects: In this small cotton filling machine, cotton is put into the machine box through the cotton inlet and placed inside the cotton conveying hood. The spiral blade shaft inside the cotton conveying hood transports the cotton inside, causing it to fall to the bottom of the machine box. Then, the cotton is tumbled by the tumbling mechanism to prevent it from blocking the internal channels of the machine box during filling. Finally, the tumbling mechanism and the cotton around it are inflated by an air pump, so that the cotton is filled into the textile through the filling tube, thereby achieving the effects of anti-clogging function and increasing filling efficiency.
