Description

Technical Field

[0001] The utility model relates to the technical field of dust collecting bags, in particular to a non-woven dust collecting bag which is convenient for edge sealing processing. Background Art

[0002] The dust bag is the core component of the bag dust collector and the "heart" of the bag dust collector. The dust bag has two main functions: one is to remove dust by filtration; the other is to recycle the waste collected by the bag dust collector, which is of great significance in life.

[0003] In the production process of dust bags, a key link is to use an ultrasonic edge banding machine to seal the edges of the dust bags. At present, most of the dust bags on the market adopt a rectangular design. When performing edge banding, it is usually necessary to seal the four sides of the rectangle in turn. This operation process is relatively cumbersome, which not only increases the difficulty of operation for workers, but also leads to a decrease in the efficiency of dust bag edge banding. Therefore, improving the efficiency of edge banding has become an urgent problem to be solved in the production process of dust bags.

[0004] Therefore, it is necessary to provide a new non-woven dust bag that is convenient for edge sealing processing to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a non-woven dust bag which is convenient for edge sealing processing.

[0006] The utility model provides a non-woven dust bag that is convenient for edge sealing processing, comprising: a first non-woven fabric sheet, a second non-woven fabric sheet, a third non-woven fabric sheet and a clamping plate, wherein the lower surface of the first non-woven fabric sheet is symmetrically fixedly connected with the second non-woven fabric sheet, a third non-woven fabric sheet is arranged below the first non-woven fabric sheet, and the upper surface of the third non-woven fabric sheet is fixedly connected to the lower surface of the second non-woven fabric sheet, and the upper surface of the first non-woven fabric sheet is fixedly connected with the clamping plate; a positioning hole and a feeding hole, a positioning hole is opened on the central surface of the clamping plate, and the central surface of the first non-woven fabric sheet is fixedly connected with the clamping plate; a positioning hole and a feeding hole are opened on the central surface of the clamping plate, and a positioning hole is opened on the central surface of the first non-woven fabric sheet. A feeding hole is provided on the surface, the lower surface of the first non-woven fabric sheet is fixed to the upper surfaces of the two second non-woven fabric sheets, and the lower surfaces of the two second non-woven fabric sheets are fixed to the upper surface of the third non-woven fabric sheet to form the prototype of the dust collecting bag. When edge sealing processing is required, the second non-woven fabric sheet is bent and folded, and the edge sealing position forms an isosceles trapezoid. A partition is placed at the folding part of the second non-woven fabric sheet and put into an ultrasonic edge banding machine. Edge sealing can be performed at one time, and the clamp plate is convenient for shaping. The dust absorbed by the vacuuming equipment enters the dust collecting bag through the positioning hole and the feeding hole.

[0007] Preferably, the positioning hole and the feed hole are positioned coincidently, and the positioning hole and the feed hole have the same diameter and length, thereby ensuring that the diameters of the positioning hole and the feed hole are the same, thereby preventing the positioning hole and the feed hole from affecting the normal entry of dust due to their different diameters, and ensuring the accurate positions of the positioning hole and the feed hole.

[0008] Preferably, the edge sealing portions on both sides of the first non-woven fabric sheet and the third non-woven fabric sheet are designed in isosceles trapezoidal shape, and the edge sealing portions of the two second non-woven fabric sheets are designed in isosceles triangle shape. When performing the edge sealing process, it is ensured that the edge sealing portions of the first non-woven fabric sheet, the second non-woven fabric sheet and the third non-woven fabric sheet can fit tightly together. The second non-woven fabric sheet is folded, and a partition is processed at the folded position to facilitate one-time edge sealing.

[0009] Preferably, the first non-woven fabric sheet and the third non-woven fabric sheet have the same length and width, and the specific length and width of the first non-woven fabric sheet and the third non-woven fabric sheet are determined. In the process of producing the raw materials of the first non-woven fabric sheet and the third non-woven fabric sheet, they can be produced synchronously, and the first non-woven fabric sheet and the third non-woven fabric sheet are distinguished by opening a feed hole on the central surface of the first non-woven fabric sheet.

[0010] Preferably, the clamp plate is made of rubber material, which has good wear resistance, high elasticity, tear strength and elongation, and is the raw material for making tapes, hoses and rubber shoes. When the clamp plate is squeezed for a long time, it will not easily break and cause damage.

[0011] Preferably, a sealing ring is fixedly connected to the inner wall of the positioning hole, which increases the sealing performance of the positioning hole. When the dust collection device and the clamp plate are firmly connected, the sucked dust will not leak out from the gap between the positioning holes, thereby improving the practicality of the positioning hole.
