[0002] A garment fabric dyeing machine is a device used to evenly coat or penetrate dye into textile fabrics. Its main function is to control factors such as dye concentration, temperature, time, and mechanical force to achieve the desired color and quality during the dyeing process. Depending on the dyeing process and fabric type, there are various types of dyeing machines, including spray dyeing machines, flatbed printing machines, sizing dyeing machines, and automatic dyeing machines. The working principle of a garment fabric dyeing machine typically involves passing the fabric through a dyeing liquid and controlling the pressure, temperature, and time to allow the fabric fibers to fully absorb the dye. Common dyeing methods include immersion dyeing, spray dyeing, and continuous dyeing.

[0003] The existing Chinese utility model patent with publication number CN214032958U provides a garment fabric dyeing device. This device facilitates dust removal before dyeing, extrusion after dyeing, and adjustment of the dyeing height to facilitate dye mixing and prevent dye sedimentation over time. However, its shortcomings lie in the fact that this device uses paddles to mechanically agitate the dye. When the fabric is loose, it is easy for the dye to become entangled on the paddles, leading to fabric damage and paddle damage. Furthermore, the individual dyeing process results in slow dye absorption efficiency and uneven dyeing. Utility Model Content

[0004] The purpose of this invention is to provide a garment fabric dyeing machine that solves the problems of fabric easily getting tangled on the stirring blades, slow dye absorption efficiency, and uneven dyeing in existing dyeing equipment.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1: This embodiment provides a garment fabric dyeing machine, specifically as follows: Figure 1 , Figure 3 As shown, it includes: A dyeing box is used to hold dyes for dyeing fabrics. The dyeing section, installed on the dyeing box, is used to immerse the fabric in dye; it includes a support 103 and a set of holding rollers 106 and dyeing rollers 107 installed on the support 103, the dyeing rollers 107 being arranged between the holding rollers 106, and the fabric being wrapped around the holding rollers 106 and dyeing rollers 107. A dye circulation unit, installed on the dyeing tank, is used to prevent dye deposition while improving the dyeing quality of the fabric. It includes a spray pipe assembly 104, an extraction pipe 114, a conveying pipe 115, and a pump 105. The pump 105 is located outside the dyeing tank. The spray pipe assembly 104 is located at the bottom of the dyeing tank and below the fabric. The pump 105 is located on the conveying pipe 115. The conveying pipe 115 is connected to the spray pipe assembly 104 and the extraction pipe 114 respectively. The extraction pipe 114 extracts the upper layer of dye and sprays it out from the spray pipe assembly 104.

[0024] During operation, the external winding machine pulls the fabric, causing it to move. The holding roller 106 keeps the two ends of the fabric aligned with the fabric movement holes on the dyeing tank. The dyeing roller 107 presses the fabric down into the dye. At this time, the pump 105 starts, and the dye is drawn from the extraction pipe 114 and then sprayed from various spray points on the spray pipe assembly 104, flowing onto the fabric. The fabric is impacted by the dye, enabling it to be dyed more quickly and evenly. Furthermore, the dye is sprayed upwards from the bottom of the dyeing tank and then extracted from the dye liquid surface by the extraction pipe 114, which completes the circulation and agitation of the dye, preventing the dye from settling.

[0025] By setting up this dye circulation section, not only can the dye impact the fabric, accelerating the dyeing efficiency and quality, but it can also continuously agitate and circulate the dye, improving the uniformity of the dye and preventing color differences during dyeing; and since no stirring blades are set, the fabric will not get tangled on the blades and cause damage.

[0026] Example 2: This embodiment further expands the dye circulation section based on the above embodiment, specifically as follows: Figures 3-6 As shown, the dye circulation section also includes a filter assembly, which is disposed between the extraction pipe 114 and the delivery pipe 115. This filter assembly is used to filter fabric fibers and other impurities from the dye. This improves dye purity and quality, prevents excessive fiber adhesion to the fabric surface, and reduces fiber damage to the pump 105.

[0027] Furthermore, the filter assembly includes a filter box, in which a filter screen mounting base 119 is provided. A filter screen 118 is inserted into the filter screen mounting base 119, and the filter screen mounting base 119 is provided with at least two slots for inserting the filter screen 118. Because two slots are provided, when the filter screen 118 needs to be replaced, the operator only needs to insert a clean filter screen 118 first, and then remove the filter screen 118 to be replaced. During this process, all dye liquid flowing to the pump 105 is filtered, avoiding the situation where only one slot is provided, resulting in unfiltered dye flowing directly to the pump 105 during filter screen 118 replacement.

[0028] Furthermore, the filter box includes a filter box body 110, a filter box cover 116, and a buckle 117. The filter box cover 116 is rotatably connected to the filter box body 110, and the buckle 117 is used to lock the filter box cover 116 onto the filter box body 110. The filter screen mounting base 119 is slidably connected to the filter box body 110, and a spring 120 and a pressure alarm 121 are provided between the filter screen mounting base 119 and the filter box body 110. The pressure alarm 121 is a commercially available product and will not be described in detail here.

[0029] When the latch 117 locks the filter box cover 116 onto the filter box body 110, the filter screen mounting base 119 completely divides the impregnation box into two parts, which are only connected by the filter screen 118. When the filter screen 118 begins to be gradually clogged by impurities or fibers, since the flow rate at the pump 105 does not decrease, the negative pressure causes the filter screen mounting base 119 to move within the impregnation box, compressing the spring 120 until the filter screen mounting base 119 touches the pressure alarm 121. At this point, pressing... Alarm 121 sounds an alarm to remind staff that filter 118 is clogged and needs to be replaced immediately. To replace it, staff remove clip 117, open filter box cover 116, replace the clogged filter 118, remove the clogged filter 118, and then lock filter box cover 116. Since the new filter 118 is not clogged, the filter mounting bracket 119 will return to its original position under the action of spring 120, until filter 118 becomes clogged again. This design allows filter 118 to be automatically alerted to replacement without requiring manual visual inspection, making it convenient, quick, and efficient.

[0030] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0031] Example 3: This embodiment further expands the dyeing section based on the above embodiment, specifically as follows: Figure 1 , Figure 2 As shown, the dyeing section also includes an extrusion group mounted on the bracket 103. The extrusion group is disposed between the dyeing roller 107 and the holding roller 106. The extrusion group includes a set of extrusion rollers 108, and the dyed fabric is inserted between the extrusion rollers 108.

[0032] A set of extrusion rollers 108 are used to continuously squeeze the passing fabric, so that the excess dye attached to the fabric after dyeing can be squeezed off here, reducing dye waste and facilitating the subsequent drying process.

[0033] Furthermore, the dyeing section also includes a cleaning group installed on the bracket 103. The cleaning group is located between the dyeing roller 107 and the holding roller 106. The cleaning group includes a cleaning box 111, a negative pressure pipe 109, and a set of cleaning rollers 112. The fabric is inserted between the cleaning rollers 112 and begins to be immersed in dye after cleaning is completed.

[0034] The negative pressure pipe 109 is connected to an external suction device. When the fabric starts to move, a set of cleaning rollers 112 will rub the fabric surface, so that the surface fibers and impurities can be separated into the cleaning box 111. Then, under the negative pressure of the external suction device, they are discharged along the negative pressure pipe 109, reducing the amount of impurities that soak into the dye and keeping the dye clean.

[0035] Furthermore, the cleaning roller 112 is provided with a cleaning block 113, which is a truncated cone shape with smooth ends, used to clean fibers adhering to the fabric surface. The cleaning block 113 can improve its efficiency in removing fibers and impurities from the fabric surface.

[0036] Furthermore, a dryer is installed on the dyeing box. The dyeing box includes a dyeing box body 101 and a dyeing box cover 102. The dyeing box cover 102 is detachably installed on the dyeing box body 101, and the bracket 103 is installed on the dyeing box cover 102. After the fabric is squeezed by the squeeze roller 108, the dryer begins to dry the fabric. The detachable dyeing box cover 102 allows the dyeing box cover 102 to seal the dyeing box body 101 during daily operation, preventing external impurities from falling into the dye.

[0037] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
