Description

Technical Field

[0001] The present invention relates to the technical field of textile desizing, and particularly relates to a desizing device for efficient water circulation fabric desizing. Background Art

[0002] In the production process of textiles, desizing is a crucial step. Desizing refers to the process of removing the sizing agent on the fabric to improve the subsequent processing performance of the fabric. Before weaving, in order to improve the breaking strength and wear resistance of the warp yarn, the warp yarn is usually sized. However, these sizing agents will affect the wettability, dyeing uniformity and hand feeling of the fabric, so they need to be removed in the subsequent process.

[0003] Chinese Patent with application number 201810228280.X discloses a desizing method for fabrics, in which the fabric to be processed is sequentially subjected to plasma treatment, drying treatment and desizing treatment during the process of being conveyed on the conveying mechanism; wherein, before the plasma treatment, the moisture regain of the fabric is controlled to be 3%-8%, the moving speed of the fabric on the conveying mechanism is 50-70m / min, and in the drying treatment, the moisture regain of the fabric treated by plasma is controlled to be 2%-7%; this invention can realize the continuous production of the plasma treatment and desizing treatment processes, and has the advantages of high desizing rate, fast desizing speed, and can greatly reduce the use amount of chemicals in the desizing liquid and thus reduce pollution.

[0004] Chinese Patent with application number 202011251190.6 discloses a desizing and washing device for relatively thick fabrics, including a box body, an installation space is arranged inside the box body, and a cleaning mechanism is arranged inside the installation space. The cleaning mechanism includes a cleaning box fixedly connected to the lower inner wall of the installation space. This invention is provided with a cleaning mechanism, which can clean the surface of the fabric to prevent the fluff on the fabric surface from affecting the desizing effect. By tightening the fabric to the entrance of the liquid absorption box and making the desizing agent penetrate through the fabric by suction, even if the fabric is relatively thick, a good desizing effect can be achieved, ensuring that high-quality products can be obtained in the subsequent processing and dyeing processes.

[0005] Traditional desizing processes have problems such as large water consumption and low desizing efficiency. Moreover, when desizing fabrics similar to the above-mentioned prior art, multiple transmission shafts are arranged in the desizing tank to tension the fabric and drive the fabric to move in the desizing tank, so that the desizing liquid can be in full contact with the fabric for desizing. However, during the contact process between the fabric and the transmission shaft, if the surface of the shaft body becomes rough due to aging or adsorption of foreign objects, the fabric will be scratched and the surface of the fabric will be damaged and unusable.

[0006] Meanwhile, to improve the desizing effect on fabrics, multiple desizing tanks are usually set up to desize the fabrics multiple times. If the desizing liquid in the same desizing tank is not replaced for a long time, its desizing ability for the fabrics will decline. If the desizing liquid is replaced frequently, it will cause unnecessary waste, which is not conducive to production. Moreover, the desizing liquid will separate after standing for a long time, affecting the desizing effect on the fabrics.

[0007] Therefore, it is necessary to invent a desizing device for efficient water circulation fabric desizing to solve the above problems. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention

[0042] First embodiment

[0043] As Figure 1 shown, the present invention provides a fabric desizing process with efficient water circulation, including the following steps

[0044] S1. Pretreatment of textile fabric: Use a carding machine to card the fabric 1 and perform deep cleaning and impurity removal on the fabric 1

[0045] S2. Prepare desizing liquor: According to the type of the fabric 1, prepare desizing liquor and put the desizing liquor into the desizing equipment for mixing

[0046] S3. Padding and desizing of textile fabric: Put the fabric 1 into the desizing equipment containing desizing liquor through a transmission device and perform padding treatment on the fabric 1

[0047] S4. Post-treatment of textile fabric: Keep the fabric 1 after padding treatment at a certain temperature and stack it, and wash the fabric through a water washing device to remove the residual desizing liquor and sizing agent

[0048] Among them, the padding treatment of fabric 1 in S3 is specifically a high-temperature padding treatment method, and the used desizing liquor in the desizing equipment is recycled by a purification and recovery equipment. There are multiple desizing equipments, and the multiple desizing equipments are connected end to end to perform desizing on fabric 1 multiple times. The desizing equipment at the head end is connected to the transmission device, and the desizing equipment at the tail end is connected to the water washing equipment.

[0049] Compared with the traditional fabric desizing process, this embodiment can recycle the wastewater generated during the desizing process, remove the sizing residues, oils and other pollutants in the wastewater through physical, chemical or biological methods, make the water quality meet the standard for reuse, greatly reduce the demand for fresh water, and save a large amount of water while ensuring the desizing effect of the textile fabric compared with the traditional process.

[0050] Second Embodiment

[0051] As Figure 2 shown, this embodiment provides a desizing equipment for efficient water circulation fabric desizing. The equipment includes a connecting part 2, and a padding part 3 is fixedly connected to the connecting part 2. A conveying part 4 is provided at both ends of the padding part 3. A conveying part 5 is provided in the padding part 3. Fabric 1 passes through multiple padding parts 3 in sequence through the conveying part 4. A temperature sensor is provided in the padding part 3, and the temperature sensor is used to detect the temperature of the desizing liquor in the padding part 3. The padding part 3 is provided with a heating element. By setting a temperature sensor in the padding part 3 to detect the temperature of the desizing liquor in real time, and controlling the heating element to heat the desizing liquor according to its temperature change, the temperature of the desizing liquor in the padding part 3 is always kept within a preset range, so as to ensure the desizing effect of the desizing liquor on fabric 1. At the same time, through the setting of multiple conveying parts 4, fabric 1 can pass through multiple desizing equipments in sequence for multiple desizing, further improving the desizing effect of the device.

[0052] As Figure 3 shown, the connecting part 2 includes multiple first connecting rods 21. Multiple second connecting rods 22 are provided between two first connecting rods 21 on the same side. Multiple load-bearing rods 23 are provided between the second connecting rods 22 at the bottom on both sides. Multiple support rods 24 are fixedly connected to the bottom of the second connecting rods 22 at the bottom. Adjacent desizing equipments are connected by the same first connecting rod 21. By respectively arranging multiple second connecting rods 22 at both ends of a first connecting rod 21, multiple desizing equipments are connected together, so that fabric 1 can pass through multiple desizing equipments in sequence for desizing operations, further improving the desizing effect on fabric 1. At the same time, through the setting of multiple desizing equipments, the problem that the desizing effect is not ideal due to excessive use of the desizing liquor in the desizing equipment can be avoided.

[0053] As Figures 4 - 5As shown in the figure, the padding section 3 includes a housing 31 which is fixedly installed on the connecting section 2. In the middle of the inner cavity of the housing 31, a plurality of desizing tanks 32 are provided. Adjacent two desizing tanks 32 are partitioned by the same limiting member 33. At both ends of the inner cavity of the housing 31 distributed along the length direction, a feed tank 34 and a discharge tank 35 are respectively provided. A plurality of observation windows 38 are fixedly connected to the housing 31, and the observation windows 38 correspond to the desizing tanks 32 one by one. By arranging a plurality of desizing tanks 32 in the housing 31 and partitioning the plurality of desizing tanks 32 by the limiting member 33, the fabric 1 entering the housing 31 can sequentially pass through the plurality of desizing tanks 32 to complete the desizing operation. At the same time, through the arrangement of the plurality of observation windows 38, the usage situation of the desizing liquid in each desizing tank 32 can be visually observed, which is convenient for subsequent replenishment and replacement of the desizing liquid, and avoids the problem that the desizing ability cannot meet the actual usage requirements due to excessive use of the desizing liquid.

[0054] The conveying section 4 includes rotating seats. Two rotating seats on one side of the feed tank 34 are fixedly connected to the housing 31. Two rotating seats on one side of the discharge tank 35 are fixedly connected to the first connecting rod 21. A rotating roller is provided between the two rotating seats on the same side. The conveying section 5 includes conveying rollers 51. A plurality of conveying rollers 51 are sequentially arranged above the feed tank 34, the limiting member 33 and the discharge tank 35 and are rotatably connected to the housing 31. Below each desizing tank 32, a padding roller 52 is provided. The fabric 1 is fed into the feed tank 34 through the conveying section 4, and sequentially passes through a plurality of conveying rollers 51 and padding rollers 52 and moves towards the discharge tank 35, and the fabric 1 is sent out of the padding section 3 by the conveying section 4. When desizing operation needs to be carried out on the fabric 1, the rotating roller is driven to rotate by a motor, so that the fabric 1 moves into the feed tank 34, and the fabric 1 is moved into a desizing tank 32 by the conveying roller 51 arranged on the feed tank 34. Subsequently, the padding roller 52 arranged in the desizing tank 32 continues to drive the fabric 1 to move into the second desizing tank 32 and makes it turn and move into the second desizing tank 32 through the conveying roller 51 arranged on the limiting member 33. At the same time, the padding roller 52 in the second desizing tank 32 drives the fabric 1 to move towards the conveying roller 51 on the discharge tank 35, and the desizing operation on the fabric 1 is completed.

[0055] It should be noted that when the fabric 1 is conveyed multiple times by a plurality of conveying rollers 51 and padding rollers 52, a section of the fabric 1 located in the desizing equipment is distributed in an "S" shape, so that the fabric 1 continuously contacts the desizing liquid in the plurality of desizing tanks 32 and completes the desizing operation.

[0056] A dust removal member 36 is provided in the feed tank 34. The dust removal member 36 is fixedly connected to the side wall of the desizing tank 32 close to the feed tank 34, and one end of the dust removal member 36 penetrates the side wall and extends into the desizing tank 32. A water absorption member 37 is also provided in the feed tank 34. The water absorption member 37 is fixedly connected to the inner wall of the housing 31. By respectively arranging the dust removal member 36 and the water absorption member 37 in the feed tank 34, when the fabric 1 moves from the feed tank 34 to the desizing tank 32, the impurities adsorbed on the fabric 1 and the desizing liquid are first scraped and cleaned, thus avoiding the problem that the impurities on the fabric 1 contaminate the desizing liquid too much.

[0057] The third embodiment

[0058] Based on the desizing equipment of the above embodiments, the operator found that the equipment has the problem of large water consumption. At the same time, when the fabric 1 is desized, during the contact process between the fabric 1 and the transmission shaft, the surface of the shaft body will become rough due to the aging of the transmission shaft or the adsorption of foreign objects, thus scratching the fabric 1 and causing the surface of the fabric 1 to be damaged and unusable. And if the desizing liquid in the same desizing tank 32 is not replaced for a long time, its desizing ability for the fabric 1 will decline. If the desizing liquid is replaced frequently, it will cause unnecessary waste and is not conducive to production. At the same time, the desizing liquid will separate after standing for a long time, and the device cannot effectively clean the impurities suspended on the desizing liquid, thus affecting the desizing effect.

[0059] Therefore, to solve the above technical problems, the device is improved according to the method described in this embodiment.

[0060] As Figures 6 - 10 shown, the conveying part 5 further includes a collecting roller 53. The collecting roller 53 is arranged above the desizing tank 32. One end of the collecting roller 53 penetrates the housing 31 and is in transmission connection with the rotating motor. The other end of the collecting roller 53 penetrates the housing 31 and is connected with a conveying pipe 54. The other end of the conveying pipe 54 is communicated with the padding roller 52 in another desizing tank 32. A water pumping part 56 is arranged on the conveying pipe 54. The collecting roller 53 and the padding roller 52 have the same structure. The collecting roller 53 is provided with a plurality of water outlet holes 55 in an annular array along the axial side. The collecting roller 53 is of a hollow structure, and the inner cavity of the collecting roller 53 is communicated with the conveying pipe 54. By arranging the collecting roller 53 above the desizing tank 32 and connecting one end of the collecting roller 53 with the conveying pipe 54, and at the same time connecting the other end of the conveying pipe 54 with the padding roller 52 in another desizing tank 32, when the rotating motor drives the collecting roller 53 to rotate, by controlling the water pumping part 56 to work, under the suction force, the collecting roller 53 sucks the desizing liquid in one desizing tank 32 into the conveying pipe 54 and conveys it to another desizing tank 32 through the conveying pipe 54, so as to realize the recycling of the desizing liquid.

[0061] It should be noted that when the desizing operation is carried out on the fabric 1, in order to ensure the desizing effect, multiple desizing devices need to be set. Refer to Figure 6As shown in the figure, taking the setting of two desizing devices as an example, when it is necessary to recycle the desizing liquid, the desizing liquid that contacts the fabric 1 later is transported to the desizing tank 32 that contacts the fabric 1 first through the water pumping part 56. Since the components for desizing in the desizing liquid that contacts the fabric 1 later are relatively pure compared to the components for desizing in the desizing liquid that contacts the fabric 1 first, transporting the desizing liquid that contacts the fabric 1 later to the desizing tank 32 that contacts the fabric 1 first can improve the purity of the desizing liquid in the desizing tank 32 that contacts the fabric 1 first. At the same time, the formulated desizing liquid is sent into the desizing tank 32 that contacts the fabric 1 later through the transfer pipe 54, and the desizing liquid that contacts the fabric 1 first is sent into the purification and recovery device through the transfer pipe 54 for purification treatment and secondary use, thereby realizing the efficient recycling of the desizing liquid, greatly avoiding the problem of desizing liquid waste. At the same time, by continuously replacing the desizing liquid, the desizing effect of the desizing liquid on the fabric 1 in each desizing tank 32 is further improved, and the problem of the decline in desizing ability caused by excessive use of the desizing liquid is avoided.

[0062] A scraping part 6 is provided on the limiting part 33. The scraping part 6 includes a base 61. The base 61 is fixedly connected to the top of the limiting part 33. Two telescopic parts 62 are symmetrically arranged at both ends of the base 61 distributed in the width direction. One connecting part 63 is fixedly connected to the end of each telescopic part 62 away from the base 61. An elastic part 64 is fixedly connected between the two connecting parts 63. The elastic part 64 is arranged in the upper half area of the two connecting parts 63, and the telescopic part 62 is arranged in the lower half area of the connecting part 63. The elastic part 64 includes an elastic layer and a cleaning layer. The elastic layer is located below the cleaning layer. The cleaning layer includes a water-absorbing sponge.

[0063] First, when it is necessary to move the fabric 1 from the feeding tank 34 to the first desizing tank 32, the conveying roller 51 arranged above the feeding tank 34 is controlled to drive the fabric 1 to move into the first desizing tank 32. When it is necessary to move the fabric 1 from the first desizing tank 32 to the second desizing tank 32, the dipping roller 52 in the first desizing tank 32 and the conveying roller 51 arranged on the limiting part 33 are controlled to drive the fabric 1 to move from the first desizing tank 32 to the second desizing tank 32. During this process, the collecting roller 53 in the second desizing tank 32 transports the desizing liquid in the second collecting roller 53 to the dipping roller 52 in the first desizing tank 32 through the working of the water pumping part 56, and discharges it through a plurality of water outlet holes 55 arranged on the dipping roller 52. At this time, since the dipping roller 52 keeps rotating, the water flow sprayed out by the dipping roller 52 contacts the fabric 1 to drive the fabric 1 to move instead of the transmission shaft, thereby avoiding the problem that the surface of the fabric 1 is scratched during the moving process and cannot be used continuously later.

[0064] Secondly, the rotation of the padding roller 52 causes the water ejected from the water outlet holes 55 to contact the surface of the fabric 1 and scour the surface of the fabric 1. On the one hand, the desizing liquor can fully penetrate into the fabric 1 to improve the desizing effect on the fabric 1. On the other hand, new desizing liquor is discharged to the bottom of the desizing tank 32 and the desizing liquor is secondarily mixed under the rotation of the padding roller 52, thereby avoiding the problem of precipitation and stratification of the desizing liquor after being placed in the desizing tank 32 for a long time, and further improving the desizing effect of the device on the fabric 1.

[0065] Thirdly, when it is necessary to clean the impurities adsorbed on the upper and lower surfaces of the fabric 1 located in the desizing tank 32, the telescopic member 62 is controlled to extend away from the base 61, so that the elastic member 64 provided on the telescopic member 62 is changed from a bent state to a horizontal state through the connecting member 63. At this time, the side of the elastic member 64 will contact the lower surface of the fabric 1 and scrape off the impurities adsorbed on the lower surface of the fabric 1. At the same time, by controlling the suction force of the water pumping part 56, the amount of water discharged outward by the padding roller 52 is changed, so that the desizing liquor discharged from the water outlet holes 55 flushes the upper surface of the fabric 1, separates the impurities adsorbed on the upper surface of the fabric 1 from the fabric 1, and the impurities move upward under the drive of the water flow. The collecting roller 53 collects and processes the impurities, thereby avoiding the problem that the excessive impurities adsorbed on the surface of the fabric 1 cause the fabric 1 to not be in full contact with the desizing liquor.

[0066] Finally, when it is necessary to clean the surface of the collecting roller 53 provided above the limiting member 33, the water pressure of the desizing liquor discharged outward by the padding roller 52 is controlled to become smaller, thereby reducing the tension of the fabric 1 and making the fabric 1 slide relative to the collecting roller 53 provided on the limiting member 33. At this time, the collecting roller 53 here cannot drive the fabric 1 to move continuously. At the same time, by controlling the telescopic member 62 to move towards the base 61, the elastic member 64 is changed from a horizontal state to an upwardly bent state, so as to contact the bottom of the collecting roller 53 here and scrape off the impurities adsorbed on the collecting roller 53, thereby avoiding the problem that the impurities adsorbed on the collecting roller 53 scratch the surface of the fabric 1 when contacting the fabric 1 under the extrusion force. At the same time, by controlling the size of the water flow ejected from the padding roller 52, the tension of the fabric 1 can be adjusted according to the thermal expansion and contraction of different fabrics 1, avoiding the problem that the fabric 1 is overstretched and broken during the desizing process.

[0067] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
