Description

Technical Field

[0001] The utility model belongs to the technical field of dyeing equipment, and in particular relates to a dyeing machine for cotton yarn production and processing. Background Art

[0002] Exhaust dyeing, also known as exhaust dyeing, is a dyeing method. Specifically, it is a method of immersing the dyed material in a dye bath containing the dye and necessary auxiliaries. The dye is gradually dyed into the dyed material through dye bath circulation or movement of the dyed material. This method is characterized by uniform coloring and low equipment requirements. It can be operated either manually or mechanically. During the dyeing process, the dyeing is a complex physical and chemical process involving multiple stages such as dye dissolution, adsorption, diffusion and fixation. Exhaust dyeing is one of the most commonly used dyeing methods in the textile printing and dyeing industry, and is suitable for dyeing yarn, knitted fabrics and some woven fabrics.

[0003] Patent application number 202210300529.X discloses a dyed yarn dyeing device with a combing structure and a dyeing method thereof. The application uses a partition to put dye and clean water into two grooves of the dyeing tank respectively, installs a reel wrapped with yarn through a first mounting rod, fixes an empty reel through a second mounting rod, and fixes one end of the yarn to the empty reel. The two sections of the undyed yarn are immersed in the dye and clean water respectively through the combing mechanism, and the yarn is passed through the dye and then into the clean water to clean the surface and then wound on the empty reel through the second mounting rod. The spacing between the clamping wheels is adjusted by the spacing adjustment mechanism, thereby adjusting the spacing. The distance between the yarn entering the dye and the clean water is adjusted to prevent the yarns from being entangled, which solves the problem that the existing dyeing device cannot adjust the spacing between multiple yarns, and the colored yarns in the dye are prone to entanglement; combined with the above application, and compared with the existing dyeing device, when using dyeing, when the cotton yarn is dyed and taken out of the dyeing tank, the dyed cotton yarn will absorb some residual dye solution, causing waste of dye solution. At the same time, it may also cause local color difference in the dyed cotton yarn during the drying process, thereby affecting the practicality of the dyeing equipment. For this reason, we propose a dyeing machine for cotton yarn production and processing. Utility Model Content

In addition, it may also cause local color difference of the dyed cotton yarn during the drying process, thereby affecting the practicality of the impregnation dyeing equipment.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dyeing machine for cotton spinning production and processing, comprising a dyeing box, a drain pipe is installed at the bottom of the front surface of the dyeing box, a first guide wheel is installed on the top of one side of the dyeing box, a reversing line-passing wheel is installed at the bottom of one side of the dyeing box, a second guide wheel is installed on the top of the other side of the dyeing box, and the same reversing line-passing wheel is symmetrically arranged on the bottom of the other side of the dyeing box.

[0006] Preferably, the lifting adjustment frame is lifted and adjusted by a lifting screw, and the lifting limit rod passes through the top of the support frame and performs lifting and limiting.

[0007] Preferably, the convex guide wheel is installed directly above the convex guide wheel.

[0008] Preferably, compensation seats are provided on both sides of the lifting and adjusting frame, and limiting grooves are also provided on both sides of the lifting and adjusting frame. A guide wheel shaft is installed on the convex guide wheel, and both ends of the guide wheel shaft pass through the limiting grooves and limiting blocks are provided in the compensation seat, and a buffer limiting rod is installed on the inner side of the compensation seat.

[0009] Preferably, the buffer limit rod passes through the limit block, and the convex guide wheel can be raised and lowered and adjusted in the compensation seat through the guide wheel shaft and the limit block.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) The dyeing device with a liquid squeezing structure is provided. When the device is used to dye cotton yarn, the cotton yarn passes through the guide wheel and the interior of the dyeing box for dyeing. The cotton yarn can then be squeezed by the provided concave squeezing guide wheel and the convex guide wheel. The cotton yarn adsorbed with the dye liquid is dehydrated by squeezing. The dye liquid can flow back into the dyeing box after squeezing and be reused. This avoids waste and also avoids color difference on the dyed cotton yarn caused by drying of the dye liquid. This improves the practicality of the device while achieving better dyeing.

[0013] (2) In addition, when the device is used, since the cotton yarn after dyeing is squeezed through the concave extrusion guide wheel and the convex guide wheel, in order to avoid hard contact and yarn breakage when the yarn passes through, the convex guide wheel is set to have an elastic structure. During the dyeing process, the yarn can be prevented from being torn when passing through the concave extrusion guide wheel and the convex guide wheel. At the same time, the elastic installation method can be applied to the dyeing and extrusion of yarns of different thicknesses, thereby improving the practicality of the device.

A support frame 200 is fixedly installed on the top of the dyeing box 100, and a wire wheel shaft rod 201 is fixedly installed at the bottom of the support frame 200. A concave extrusion guide wheel is rotatably installed on the wire wheel shaft rod 201 202, a lifting screw 205 is installed on the top of the support frame 200, one end of the lifting screw 205 is located on the inner top of the support frame 200, and a lifting adjustment frame 203 is installed. The lifting adjustment frame 203 can be adjusted up and down by the lifting screw 205 to facilitate the passage of yarn. Lifting limit rods 206 are installed on both sides of the top of the lifting adjustment frame 203, and a convex guide wheel 204 is also rotatably installed on the bottom of the lifting adjustment frame 203. When the cotton yarn is dyed using the dip dyeing device in the application, the yarn The yarn passes through the first guide wheel 102 and the reversing wire wheel 103 to the reversing wire wheel 103 at the bottom of the other side, and passes through the second guide wheel 104, and then passes through the bottom of the support frame 200. When the yarn passes through, 105 is rotated to lift the lifting adjustment frame 203 to a certain height. Then, after the yarn passes around the concave extrusion guide wheel 202, the lifting screw 205 is rotated to lower the lifting adjustment frame 203 to a certain height to ensure that the yarn passes through the concave extrusion guide wheel 202 and the convex guide wheel 204 for extrusion.

[0021] Specifically, the lifting and adjusting frame 203 is lifted and adjusted by the lifting screw 205, and the lifting limit rod 206 passes through the top of the support frame 200 and performs lifting and limiting to ensure the stability of the lifting and adjusting frame 203 when working.
