[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] The following is combined with Figure 1-5Detailed description, a cotton knitted fabric oxidative impregnation bio-enzyme pretreatment system comprises an empty water washing box 101, two empty soaking boxes 102, two supporting legs 103, two limiting rollers 104, two contact rollers 105, two limiting support plates 106 and two winding rollers 107, both ends of the empty water washing box 101 are fixedly connected to the empty soaking box 102 by welding, the two supporting legs 103 are fixedly connected to the bottom of the two empty soaking boxes 102 by welding, the two limiting rollers 104 are respectively rotatably connected to the two sides above the empty water washing box 101 by shafts, the two contact rollers 105 are both rotatably connected in the empty water washing box 101 by shafts, the two limiting support plates 106 are respectively fixedly connected in the two empty soaking boxes 102 by welding, and the two winding rollers 107 are respectively rotatably connected to the two limiting support plates 106.

[0031] Furthermore, water is stored in the washing empty box 101, and the water in the washing empty box 101 can be poured onto the cotton knitted fabric to complete the pretreatment of the cotton knitted fabric and the removal of the oxidative impregnation biological enzyme on the cotton knitted fabric. The two soaking empty boxes 102 can store hydrogen peroxide, and the two rolls of cotton knitted fabric can be soaked in the two soaking empty boxes 102. During the soaking process, the oxidative impregnation biological enzyme on the cotton knitted fabric can be treated for the first time, and then the two rolls of cotton knitted fabric that have been soaked can be washed to complete the removal of the oxidative impregnation biological enzyme on the cotton knitted fabric. The bottom of the washing empty box 101 and the two soaking empty boxes 102 are fixedly connected with drain pipes with valves, and the water and hydrogen peroxide in the washing empty box 101 and the two soaking empty boxes 102 are discharged through multiple drain pipes with valves. The two supporting legs 103 are used to support and fix the device, and the device is stably placed on the ground. The two limiting rollers 104 can provide support for the two rolls of cotton knitted fabrics to prevent the two rolls of cotton knitted fabrics from directly contacting the edge of the washing empty box 101, thereby playing a protective role and preventing the two rolls of cotton knitted fabrics from being scratched by the washing empty box 101. The two contact rollers 105 can be used to limit the two rolls of cotton knitted fabric. The two rolls of cotton knitted fabric first contact with the two limiting rollers 104, and then the two rolls of cotton knitted fabric contact with the two contact rollers 105. Finally, the two rolls of cotton knitted fabric are discharged. The two limiting support plates 106 can provide a placement space for the two winding rollers 107. The two rolls of cotton knitted fabric can be wound on the two winding rollers 107 respectively, and then the two winding rollers 107 are placed on the two limiting support plates 106. At this time, the two rolls of cotton knitted fabric wound on the two winding rollers 107 will be immersed in the two soaking In the empty box 102, the first step of removing the oxidative impregnation biological enzyme on the two rolls of pure cotton knitted fabric is completed. After soaking for a period of time, the two rolls of pure cotton knitted fabric are taken out and contacted with two limiting rollers 104. Then, the two rolls of pure cotton knitted fabric are placed in the empty water washing box 101 and contacted with two contact rollers 105. After that, the two rolls of pure cotton knitted fabric are transmitted out and are wound around two external collecting rollers. The two rolls of pure cotton knitted fabric are collected by rotating the two collecting rollers, and the two rolls of pure cotton knitted fabric that have been washed are collected, and the treatment of the oxidative impregnation biological enzyme on the two rolls of pure cotton knitted fabric is completed.

[0032] The following is combined with Figure 1-4In detail, the pretreatment system also includes two groups of two notched round rods 201, two groups of two horizontal vertical plates 202 and two bidirectional lead screws 1203. The two groups of two notched round rods 201 are respectively slidably connected to the two immersion empty boxes 102 through grooved circular holes, the two groups of two notched round rods 201 are respectively slidably connected to the two ends of the two winding rollers 107 through circular holes, the two groups of two horizontal vertical plates 202 are respectively fixedly connected to the two groups of two notched round rods 201 through welding, the two bidirectional lead screws 1203 are respectively rotatably connected to the two immersion empty boxes 102 through circular holes, and the two ends of the two bidirectional lead screws 1203 are respectively threadedly connected to the two groups of two horizontal vertical plates 202.

[0033] Furthermore, a plurality of notches are provided on the notched round rod 201. When the notched round rod 201 is slidably connected to the soaking empty box 102 and limited, the notched round rod 201 can only slide forward and backward, and two groups of two notched round rods 201 are used to limit the two winding rollers 107 to prevent the two winding rollers 107 from moving up and down. When the two winding rollers 107 are placed on the two limiting support plates 106, the two groups of two notched round rods 201 are slidably connected to the two ends of the two winding rollers 107 respectively to limit the two winding rollers 107, and two groups of two cross-linked vertical plates 202 are used to drive the two groups of two notched round rods 201 to move. The threads at both ends of the two-way lead screw I203 have opposite rotation directions. When the two-way lead screw I203 rotates, it will drive the two cross-linked vertical plates 202 connected thereto to move inward or outward at the same time, thereby changing the positions of the two groups of two notched round rods 201, and limiting or releasing the limiting of the two winding rollers 107.

[0034] The following is combined with Figure 1-3 6 is described in detail, the pretreatment system also includes a bearing seat plate I301, a reduction motor 302, a shaft circular plate 303 and a plurality of horizontal stirring vertical plates 304, the bearing seat plate I301 is fixedly connected to the water washing empty box 101 by welding, the reduction motor 302 is fixedly connected to the bearing seat plate I301 through a flange plate, the shaft circular plate 303 is fixedly connected to the output shaft of the reduction motor 302 by a keyway and a retaining spring, the water washing empty box 101 and the shaft circular plate 303 are rotatably connected through a circular hole, and a plurality of horizontal stirring vertical plates 304 are evenly fixedly connected to the shaft circular plate 303 by welding.

[0035] Furthermore, the bearing seat plate I301 can provide a fixed space for the reduction motor 302. After starting the reduction motor 302, it can drive the shaft circular plate 303 to rotate. When the shaft circular plate 303 rotates, it can drive multiple horizontal stirring vertical plates 304 to rotate. The rotation of multiple horizontal stirring vertical plates 304 can be used to stir the water in the empty washing box 101, which can keep the water in the empty washing box 101 free of impurities, further ensuring the washing effect of the two-roll cotton knitted fabric.

[0036] According to the instruction manual Figure 1-3 , 7 and 8 illustrate in detail that the pretreatment system also includes two feeding pipes 401, and the two feeding pipes 401 are fixedly connected to the front and rear ends of the water washing empty box 101 by welding.

[0037] Furthermore, two feeding tubes 401 are used to add manganese dioxide into the empty washing box 101, so that the manganese dioxide contacts and reacts with the hydrogen peroxide in the water in the empty washing box 101, and the hydrogen peroxide is converted into water, thereby ensuring that there is no hydrogen peroxide residue in the empty washing box 101. Because the two rolls of cotton knitted fabric that have been soaked are both adhered to hydrogen peroxide, when the two rolls of cotton knitted fabric enter the empty washing box 101, the hydrogen peroxide will also enter the water in the empty washing box 101. At this time, manganese dioxide is needed to treat the hydrogen peroxide, converting the hydrogen peroxide into water, thereby ensuring that there is no hydrogen peroxide in the empty washing box 101.

[0038] According to the instruction manual Figure 1-3 , 7 and 8 illustrate in detail that the pretreatment system also includes two hollow rotating chambers 402, two material storage barrels 403 and two cross supporting plates 404. The two hollow rotating chambers 402 are fixedly connected to the two feeding pipes 401 by welding, the two material storage barrels 403 are fixedly connected to the two hollow rotating chambers 402 by welding, the two cross supporting plates 404 are fixedly connected to the two material storage barrels 403 by welding, and the water washing empty box 101 is fixedly connected to the two cross supporting plates 404 by welding.

[0039] Furthermore, two horizontal support plates 404 are used to fix the two storage barrels 403. Manganese dioxide is placed in the two storage barrels 403. The manganese dioxide stored in the two storage barrels 403 enters the two feeding pipes 401 respectively through the two hollow rotating cavities 402, and finally the manganese dioxide is added to the water-washing empty box 101. After that, the rotation of multiple horizontal stirring vertical plates 304 is used to stir the water in the water-washing empty box 101, so as to accelerate the reaction of manganese dioxide and hydrogen peroxide.

[0040] According to the instruction manual Figure 1 and 7 -9 describes in detail that the pretreatment system also includes two rotating circular plates 501 and two groups of multiple communicating circular holes 502. The two rotating circular plates 501 are respectively connected in two hollow rotating cavities 402 through cavity rotation, and the two groups of multiple communicating circular holes 502 are respectively and evenly arranged on the two rotating circular plates 501.

[0041] Furthermore, the two rotating circular plates 501 can rotate in the two hollow rotating chambers 402. When the two rotating circular plates 501 rotate, they will drive the two groups of multiple connecting circular holes 502 to rotate. When the connecting circular holes 502 are connected with the hollow rotating chamber 402 and the storage barrel 403, the manganese dioxide in the two storage barrels 403 will enter the two feeding pipes 401, and finally the manganese dioxide will be added to the water washing empty box 101, so as to realize the intermittent addition of manganese dioxide to the water washing empty box 101 and prevent excessive manganese dioxide from being added to the water washing empty box 101. If more manganese dioxide enters the water washing empty box 101, the quality of water in the water washing empty box 101 will be affected.

[0042] According to the instruction manual Figure 1-3 As described in detail in 7-9, the pretreatment system also includes two bearing seat plates II601 and two bevel gear shafts 602. The two bearing seat plates II601 are fixedly connected to the front and rear ends of the water washing empty box 101 by welding, and the two bevel gear shafts 602 are respectively connected to the two bearing seat plates II601 by shaft rotation, and the two rotating circular plates 501 are respectively fixedly connected to the two bevel gear shafts 602.

[0043] Furthermore, the two bearing seat plates II601 can provide rotation space for the two bevel gear shafts 602, and the rotation of the two bevel gear shafts 602 can be used to drive the two rotating circular plates 501 to rotate, ensuring that the two groups of multiple connecting circular holes 502 on the two rotating circular plates 501 rotate, allowing the connecting circular holes 502 to be intermittently connected to the hollow rotating cavity 402 and the storage barrel 403, so as to realize the intermittent addition of manganese dioxide into the water-washing empty box 101.

[0044] According to the instruction manual Figure 1-3 6, the pretreatment system further comprises a bevel gear 701, which is fixedly connected to the shaft circular plate 303 through a keyway and a retaining spring, and the two bevel gear shafts 602 are meshed and transmission-connected with the bevel gear 701.

[0045] Furthermore, when the circular plate with shaft 303 rotates, it will drive the bevel gear 701 to rotate, and when the bevel gear 701 rotates, it will drive the two bevel gear shafts 602 to rotate, ensuring that manganese dioxide is intermittently added to the empty water washing box 101 when the water in the empty water washing box 101 is stirred. Not only can the water in the empty water washing box 101 be stirred, but also the manganese dioxide and hydrogen peroxide can be stirred, thereby shortening the reaction time of manganese dioxide and hydrogen peroxide.

[0046] According to the instruction manual Figure 1 and 10In detail, the pretreatment system also includes two vertical trough plates 801, two groups of two slide block plates 802, two squeezing rollers 803 and two bidirectional lead screws II901. The two vertical trough plates 801 are fixedly connected to the water washing empty box 101 by welding, the two groups of two slide block plates 802 are slidingly connected to the two vertical trough plates 801 through slide grooves, the two squeezing rollers 803 are rotatably connected between the corresponding two slide block plates 802 through shafts, the two bidirectional lead screws II901 are rotatably connected to the two vertical trough plates 801 through bearing holes, and the two groups of two slide block plates 802 are respectively connected to the two ends of the two bidirectional lead screws II901 through threaded transmission.

[0047] Furthermore, the two vertical groove plates 801 can provide sliding space for the two groups of two slide block plates 802, and the two groups of two slide block plates 802 can provide rotating space for the two squeezing rollers 803. When the two rolls of cotton knitted fabric are washed, the two rolls of cotton knitted fabric are allowed to enter between the two squeezing rollers 803, and the two squeezing rollers 803 are used to squeeze the two rolls of cotton knitted fabric to squeeze out the water in the two rolls of cotton knitted fabric. The squeezed water will return to the empty washing box 101 to avoid wasting water resources. The thread rotation direction is opposite. After rotating the two bidirectional screws II901, the two groups of two slide block plates 802 can be driven to move at the same time, thereby changing the distance between the two extrusion rollers 803, and completing the extrusion processing of the two-roll cotton knitted fabric with different thicknesses. When adjusting the distance between the two extrusion rollers 803, the two bidirectional screws II901 need to be rotated at the same speed at the same time, so that the two groups of two slide block plates 802 can slide at the same speed at the same time, ensuring that the two extrusion rollers 803 move smoothly and complete the extrusion processing of the two-roll cotton knitted fabric.

[0048] Furthermore, the treatment method of the all-cotton knitted fabric oxidative impregnation bio-enzyme pretreatment system, the test method comprises the following steps:

[0049] Step 1: Add water into the water-washing empty box 101, and evenly add hydrogen peroxide into the two soaking empty boxes 102;

[0050] Step 2: Winding two rolls of pure cotton knitted fabric onto two winding rollers 107 respectively, and then soaking the two rolls of pure cotton knitted fabric wound onto the two winding rollers 107 into two soaking empty boxes 102, thereby completing the first step of removing the oxidative impregnation biological enzyme on the two rolls of pure cotton knitted fabric;

[0051] Step 3: After soaking for a period of time, the two rolls of cotton knitted fabric are taken out and contacted with the two limiting rollers 104;

[0052] Step 4: Place two rolls of pure cotton knitted fabrics into the empty washing box 101 and contact them with two contact rollers 105 to complete the oxidation and impregnation bio-enzyme treatment on the two rolls of pure cotton knitted fabrics.
