Description

Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a conical water tank filter net bag. Background Art

[0002] As people's living standards improve and their environmental awareness increases, they attach great importance to the classification, collection and treatment of kitchen waste. A filter woven with fine threads is placed in the dishwashing sink. When washing dishes, clean water will flow away and kitchen waste will be filtered out. This not only delays the odor of kitchen waste, but also keeps the sewer clean and hygienic.

[0003] There are two ways to process the bottom of traditional filter bags. The first is direct sewing with an edge-covering machine. This process is labor-intensive and has long thread ends after processing, so it is gradually being eliminated. The second process is heating, melting and bonding. More elastic yarns are added to the bottom of the water-cut bag to increase the density of the fabric, and ultrasonic welding is used to fuse the bottom together. This processing technology requires dense fabric at the bottom and requires the loom to run at high speed. Cutting threads are frequently added, which increases the difficulty of the process and the defective rate of the product. In addition, the ultrasonic welding process requires relatively high ultrasonic power. Long-term work in an ultrasonic environment is harmful to the health of the operators.

[0004] In summary, the previous method of sealing the bottom of the filter bag is relatively complicated, costly, and has a high defective rate. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, provide a conical water tank filter mesh bag, and solve the technical problems of the existing water tank filter mesh bag having a bottom closed structure with complex processing, high cost and high defective rate.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The present application provides a conical water tank filter bag, which is described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0033] In order to solve the technical problems of the bottom closure structure of the water tank filter mesh bag in the prior art, such as complex processing, high cost and high defective rate, an embodiment of the present application provides a conical water tank filter mesh bag, which is described in detail below.

[0034] like Figure 1 Figure 2 As shown, a conical water tank filter bag includes

[0035] The mesh bag body 1 is a tubular fabric, one end of which is used as a bag opening, and the other end of which is used as a bag bottom;

[0036] The bottom of the mesh bag body 1 is radially gathered to form a clustering portion;

[0037] A sol is filled in the mesh bag fabric of the clustering part;

[0038] The film 2 is wound in a ring shape on the outside of the mesh bag fabric of the bundling part, the sol dissolves the film 2 to form a bonding layer, and the film 2 is connected to the bundling part via the bonding layer so that the film 2 is circumferentially bonded and wrapped around the bundling part.

[0039] Specifically, as an optional implementation in this embodiment, the sol agent is acetone; the film 2 is cellulose diacetate film 2.

[0040] As another optional implementation in this embodiment, the sol agent is methanol; the film 2 is cellulose diacetate film 2.

[0041] Acetone, methanol and cellulose diacetate film 2 are all existing mature products and can be purchased directly in the market.

[0042] The width of the film 2 is 5-30 mm, and in this embodiment the width of the film 2 is 10 mm.

[0043] The bottom fabric 11 of the mesh bag body 1 is in the ring-shaped film 2. At this time, the film 2 serves as the bottom of the entire filter bag. Although it can meet the purpose of sealing the bottom of the bag, it is easy to scratch other mesh bags because the material of the film 2 is relatively hard. To this end, this embodiment provides an optional implementation method, in which the bottom fabric 11 of the mesh bag body 1 extends out from the ring-shaped film 2, such as Figure 1 As shown, the length of the bottom fabric 11 extending out is less than 0.5 mm. The bottom fabric 11 extends out from the film 2, making the bottom of the entire filter bag softer, avoiding the film 2 at the bottom of the mesh bag from directly contacting the outside, and preventing the film 2 from scratching other mesh bags.

[0044] As an optional implementation in this embodiment, the yarn material of the mesh bag body 1 is polyester yarn.

[0045] As an optional implementation in this embodiment, the bag opening of the mesh bag body 1 is provided with a cuff 3. Weaving the cuff 3 at the bag opening is a conventional method in the art and will not be described in detail here.

[0046] The conical water tank filter mesh bag of the utility model changes the traditional method of sewing or hot melting to seal the bottom of the mesh bag, and instead uses a film 2 + sol method to seal the bottom of the bag. The filter mesh bag needs to be radially contracted first, and the bottom of the filter mesh bag is ensured not to be wrapped by the film 2. The area wrapped by the film 2 needs to be sprayed with the sol, and then after the film 2 is wrapped on the mesh bag, a chemical reaction occurs between the sol and the film 2, and the film 2 dissolves to produce viscosity, so that the film 2 can be bonded to the mesh bag to seal the bottom of the bag.

[0047] Another embodiment provided by the present application provides a conical water tank filter bag, which is described in detail below.

[0048] like Figure 3 As shown, this embodiment is based on the first embodiment, and the difference is that the conical water tank filter mesh bag of this embodiment does not have a cuff 3. The main function of the cuff 3 is to provide radial tightening force for the bag mouth of the mesh bag, so that the mesh bag can be sleeved on the water tank. In the conical water tank filter mesh bag of this embodiment, at least one elastic line 4 is arranged in the mesh bag body, and the elastic line 4 is woven in the fabric layer of the mesh bag body. One end of the elastic line 4 is connected to the bag bottom, and the other end of the elastic line 4 is connected to the bag mouth. The elastic line 4 is spirally distributed in the length direction of the mesh bag body.

[0049] The elastic line 4 is made of any one of spandex coated yarn, spandex yarn, polyester yarn, and nylon yarn. As an optional implementation in this embodiment, the elastic line 4 is made of spandex coated yarn.

[0050] The number of elastic lines 4 is determined by the manufacturer according to the radial contraction force required by the mesh bag. The number of elastic lines 4 can be set to two or more. The more elastic lines 4 there are, the greater the radial contraction force that can be provided.

[0051] Since the filter mesh bag of the present embodiment does not have a cuff 3, the elastic cord 4 is woven into the mesh bag by spiral weft knitting during the weaving process. The weaving mechanism needs to be switched when weaving on a circular loom. The mesh bag body is woven normally on the circular loom, and the elastic cord 4 is weft knitted into the mesh bag throughout the entire weaving process of the mesh bag, thereby improving the weaving efficiency of the entire mesh bag, increasing the yield rate, and reducing consumption and increasing efficiency.
