Description

Technical Field

[0001] This utility model relates to the field of nylon processing technology, and in particular to an environmentally friendly pretreatment device for nylon dyeing. Background Technology

[0002] Nylon, also known as nylon, has advantages such as high strength, high abrasion resistance, high chemical resistance, good deformation resistance, and anti-aging properties. Pretreatment of nylon is an indispensable step in the dyeing process, mainly to ensure that the dyeing effect reaches the best state. Before dyeing nylon fabric, washing is a more important part of the pretreatment process. The nylon fabric is washed to remove surface dirt or residues, so as to ensure that the dye can fully penetrate into the nylon fibers.

[0003] Common environmentally friendly pretreatment devices for nylon dyeing have a relatively simple structure. They typically use brushes to clean the top and bottom of the nylon fabric while it is moving horizontally. However, this cleaning method has certain drawbacks. When the nylon fabric is in a horizontal state, the wastewater and impurities remaining after cleaning the top cannot be removed in time. They can easily penetrate into the inside of the nylon fabric or even the bottom, causing secondary pollution. Therefore, this method is not practical enough. So, we propose an environmentally friendly pretreatment device for nylon dyeing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Common environmentally friendly pretreatment devices for nylon dyeing have relatively simple structures. Typically, the top and bottom of the nylon fabric are cleaned with a brush while the fabric is moving horizontally. However, this cleaning method has certain drawbacks. In a horizontal state, the wastewater and impurities remaining after cleaning the top of the nylon fabric cannot be removed in time and can easily penetrate into the interior of the nylon fabric or even the bottom, thus causing secondary pollution and making it impractical.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An environmentally friendly pretreatment device for nylon dyeing includes a housing, and cleaning mechanisms are symmetrically installed inside the housing near the left and right sides.

[0009] As a preferred embodiment of this utility model, an observation door is rotatably connected to the front of the housing near the top, and a sealing strip is adhered to the outer periphery of the observation door where it contacts the housing.

[0010] The technical advantages of adopting the above-mentioned further solution are: the observation door allows users to easily observe the cleaning status of the nylon fabric, and the cleaning mechanism can also be inspected and maintained through the observation door, thus improving ease of use.

[0011] As a preferred embodiment of this utility model, a filter screen is installed inside the housing near the bottom.

[0012] The technical effect of adopting the above-mentioned further solution is that dust and impurities in the cleaning water can be filtered through the filter screen, which facilitates the reuse of the cleaning water.

[0013] As a preferred embodiment of this utility model, a drainage pipe is installed at the inner bottom of the shell.

[0014] The technical advantage of adopting the above-mentioned further solution is that the filtered cleaning water can be easily discharged through the drainage pipe, thus improving the ease of use.

[0015] As a preferred embodiment of this utility model, a water inlet pipe is installed on the back side of the nozzle, extending to the back side of the housing.

[0016] The technical effect of adopting the above-mentioned further solution is that cleaning water can be continuously injected into the nozzle through the water inlet pipe, thereby improving the usage effect.

[0017] As a preferred embodiment of this utility model, the driving component includes a slide block, which is fixedly connected to the output end of the cylinder, and an electric slider is slidably connected inside the slide block, which is fixedly connected to the nozzle.

[0018] The technical effect of adopting the above-mentioned further solution is that the electric slider can drive the nozzle and cleaning brush to move back and forth inside the slide block, thereby washing the nylon fabric.

[0019] As a preferred embodiment of this utility model, the auxiliary component includes a support frame, which is fixedly connected to a slide block. A slide rod is slidably connected to the outer side of the support frame near the top and through the inner side. A scraper is fixedly installed at one end of the slide rod near the inner side. A spring is sleeved around the slide rod and between the support frame and the scraper.

[0020] The technical effect of adopting the above-mentioned further solution is that the spring can push the scraper to move inward, thereby scraping away the excess water in the washed nylon fabric, which facilitates the subsequent drying operation and improves the ease of use.

[0021] As a preferred embodiment of this utility model, the scraper is made of silicone material, and the sharp angle near the inner side is chamfered.

[0022] The technical effect of adopting the above-mentioned further solution is: the chamfering prevents the nylon fabric from being scratched by the shaving strip, thus improving the stability of use.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] In this invention, through the design of the housing and the cleaning mechanism, and by the coordinated use of the inlet, outlet, first auxiliary roller, second auxiliary roller, cylinder, drive assembly, nozzle, cleaning brush and auxiliary components, nylon fabric can be cleaned stably and efficiently. Compared with traditional cleaning methods, it can effectively prevent secondary pollution and greatly improve practicality. Attached Figure Description

The cleaning mechanism 2 includes a cylinder 201, which is fixedly installed inside the housing 1. A drive assembly 202 is fixedly installed at the output end of the cylinder 201. A nozzle 203 is installed inside the drive assembly 202, and a cleaning brush 204 is adhered to the inside of the nozzle 203. An auxiliary assembly 205 is installed at the top of the drive assembly 202.

[0036] Example 2

[0037] like Figure 1-4As shown, an observation door 105 is rotatably connected to the front of the housing 1 near the top. A sealing strip is adhered to the outer periphery of the observation door 105 where it contacts the housing 1. The observation door 105 allows the user to easily observe the cleaning status of the nylon fabric and also allows for the inspection and maintenance of the cleaning mechanism 2, improving ease of use. A filter screen 106 is installed inside the housing 1 near the bottom. The filter screen 106 can filter dust and impurities in the cleaning water, facilitating the reuse of the cleaning water. A drain pipe 107 is installed at the inner bottom of the housing 1, which facilitates the discharge of the filtered cleaning water, improving ease of use. A water inlet pipe 2031 is installed on the back of the nozzle 203 extending to the back of the housing 1. The water inlet pipe 2031 can continuously inject cleaning water into the nozzle 203, improving the usage effect. The drive assembly 202 includes a slide 2021, which is fixedly connected to the output end of the cylinder 201. An electric slider is slidably connected inside the slide 2021. 2022, the electric slider 2022 is fixedly connected to the nozzle 203. The electric slider 2022 can drive the nozzle 203 and the cleaning brush 204 to move back and forth inside the slide 2021, thereby washing the nylon fabric. The auxiliary component 205 includes a support frame 2051, which is fixedly connected to the slide 2021. A slide rod 2052 is slidably connected to the outer side of the support frame 2051 near the top and through the inner side. The inner end of the slide rod 2052 is fixedly mounted. The scraper 2053 is equipped with a spring 2054 fitted around the outer periphery of the slide bar 2052 and between the support frame 2051 and the scraper 2053. The spring 2054 can push the scraper 2053 to move inward, thereby scraping off excess water from the washed nylon fabric, facilitating subsequent drying operations and improving ease of use. The scraper 2053 is made of silicone, and the sharp corners near the inner side are beveled to prevent the scraper 2053 from scratching the nylon fabric and improve its stability during use.

[0038] The working process of this utility model is as follows: When using a nylon dyeing environmentally friendly pretreatment device to clean nylon fabric, firstly as follows... Figure 2As shown, one end of the nylon fabric is fed into the housing 1 through the inlet 101, and wound around the first auxiliary roller 103 and the second auxiliary roller 104, passing between the two cleaning mechanisms 2, and exiting from the outlet 102. Then, through the extension of the cylinder 201, the drive assembly 202 and the nozzle 203 are moved inward until the cleaning brush 204 is in contact with the surface of the nylon fabric. Then, cleaning water is continuously injected into the nozzle 203 through the water inlet pipe 2031 to spray and wet the nylon fabric. The electric slider 2022 drives the nozzle 203 and the cleaning brush 204 to reciprocate forward and backward. The nylon fabric is then slid back to wash its surface. In conjunction with the external feeding equipment, the nylon fabric is slowly pulled through the two cleaning mechanisms 2 to complete the cleaning operation. During the process, the cleaning water sprayed from the nozzle 203 washes the dust and impurities downwards into the housing 1, which can effectively prevent secondary pollution of the cleaned areas by the impurities and dust. After being filtered by the filter screen 106, the water is discharged from the housing 1 through the drain pipe 107. The spring 2054 pushes the scraper 2053 inward to remove excess water from the surface of the nylon fabric, which is convenient for subsequent drying operations.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
