Description

Technical Field

[0001] The invention belongs to the technical field of coral fleece, and in particular relates to a coral fleece fabric cleaning device. Background Art

[0002] Coral fleece is a new type of fabric. Coral fleece is a fabric made of polyester fiber, also known as polyester coral fleece. Coral fleece, as the name suggests, is a colorful, coral-shaped textile fabric with good coverage. It is a new type of fabric with fine texture, soft touch, not easy to shed, not pilling, not fading, no irritation to the skin, no allergies, beautiful appearance, rich colors, mainly used in nightgowns, baby products, children's clothing, pajamas, shoes and hats, toys, car interior accessories, handicrafts, home accessories and other fields, and is becoming more and more popular in the home textile industry. A large number of coral fleece bedding has emerged on the market, gradually replacing traditional bedding, such as coral fleece blankets, quilts, pillows, sheets, pillowcases and bedding four-piece sets, etc., which are deeply trusted by consumers.

[0003] At present, after the production of finished coral fleece fabrics, negative pressure vacuuming is used to clean the debris and dust. However, the fiber density of coral fleece fabrics is relatively high. When the broken fibers and dust are mixed deep in the fabric fibers, the traditional method of directly using vacuuming equipment to vacuum the fabric fibers is not effective due to the deep hiding problem. In addition, after the coral fleece fabrics are vacuumed, the fibers are prone to barbs, unevenness, and other flatness and softness conditions that affect the cleaning quality level.

[0004] Therefore, a coral fleece fabric cleaning device is needed to solve the problems existing in the prior art. Summary of the invention

[0005] The object of the present invention is to provide a coral fleece fabric cleaning device to solve the problems raised in the above background technology.

The fixed-point rotating seat is rotatably connected in the inner cavity of the negative pressure dust collection box, and the combing tooth plate is fixed at the center of the lower end surface of the fixed-point rotating seat. The combing tooth plate inside the negative pressure dust collection box can comb the fibers of the coral fleece fabric along the movement direction, thereby ensuring the flatness and softness of the fibers of the coral fleece fabric after vacuuming and cleaning. In addition, the combing tooth plate with elastic flipping can adapt to the fiber area depth of the coral fleece fabric during the combing process and reduce the trouble of scratching the fabric caused by hard combing; The internal lifting of the negative pressure dust box is provided with an adaptive sealing mechanism, and the adaptive sealing mechanism includes an elastic resistance shell, a spring sleeve and a telescopic slide rod. The elastic resistance shell is inserted into the interlayer of the negative pressure dust box, and the spring sleeve is arranged above the elastic resistance shell. The telescopic slide rod is slidably connected to the inside of the spring sleeve. The elastic resistance shell is adaptively fitted on the coral fleece fabric using an anti-wear gasket under the action of the rebound force of the reset spring in the spring sleeve. In this way, the elastic resistance shell and the negative pressure dust box cooperate to form a relatively sealed space to ensure the stability of the negative pressure suction and the anti-spill dust collection operation.

[0010] As a preferred implementation, one end of the torsion spring is fixed to the side surface of the flip shaft, and the other end of the torsion spring is fixed to the inner end wall of the fixed sleeve.

[0011] As a preferred embodiment, the two groups of combing tooth plates are respectively located at the front and rear sides of the inner cavity of the negative pressure dust collector box, and the spreading roller is arranged in the middle of the two groups of combing tooth plates.

[0012] As a preferred implementation, a lifting slot is provided inside the negative pressure dust collection box, and the elastic force support shell is slidably connected in the lifting slot of the negative pressure dust collection box.

[0016] Compared with the prior art, the coral fleece fabric cleaning device provided by the present invention has at least the following beneficial effects: Through the adaptive sealing mechanism, the elastic shell is adaptively fitted on the coral fleece fabric using anti-wear gaskets under the action of the rebound force of the reset spring in the spring sleeve, so that the elastic shell and the negative pressure dust box cooperate to form a relatively sealed space to ensure the stability of the negative pressure suction and prevent spillage of the dust collection operation.

[0017] Through the fiber spreading mechanism, the spreading roller spreads the fibers on the coral fleece fabric through the spreading bumps on the surface, which facilitates the negative pressure vacuuming operation of dust accumulated deep in the fibers of the coral fleece fabric and improves the situation where traditional vacuuming cleaning is not thorough enough.

[0018] Through the combing mechanism, the combing tooth plate inside the negative pressure vacuum box can comb the fibers of the coral fleece fabric along the direction of movement, thereby ensuring the smoothness and softness of the fibers after the coral fleece fabric is vacuumed and cleaned.
