Description

Technical Field

[0001] The utility model belongs to the technical field of hook-and-loop fastener dyeing, and particularly relates to a high-temperature dyeing device for hook-and-loop fasteners. Background Art

[0002] As a common connecting device, hook-and-loop fasteners have a wide range of applications in daily life. However, traditional hook-and-loop fasteners have a single color and are difficult to meet the diverse needs of the market. At present, although there are some hook-and-loop fastener dyeing technologies in the market, they often have problems such as poor color fastness, uneven color, and environmental pollution. The existing hook-and-loop fastener dyeing processes usually adopt traditional dipping or padding methods. Although these methods are simple and easy to operate, they often have problems such as high energy consumption, large amount of sewage discharge, and unsatisfactory dyeing effect. The dyes used in traditional dyeing processes often contain substances harmful to the human body and the environment, and the wastewater generated during the dyeing process is difficult to treat, causing great pressure on the environment. At the same time, the dyeing effect and color fastness of traditional processes also need to be improved.

[0003] Chinese Patent with Patent No. CN208104783U, a high-temperature dyeing device for hook-and-loop fastener production, includes a dyeing tank. The outer wall of the dyeing tank is successively provided with a temperature storage interlayer, a first rare earth heat preservation layer, a second rare earth heat preservation layer, a heat insulation and heat preservation layer, and a waterproof protection layer. The upper and lower ends of the temperature storage interlayer are respectively connected with an injection pipe and a discharge pipe. The temperature storage interlayer is filled with a phase change medium. A turntable is arranged at the bottom inside the dyeing tank. A rotating shaft is connected to the bottom of the turntable. The rotating shaft extends out of the dyeing tank and is connected with a motor. The motor is connected with a power supply. A plurality of stirring blades are arranged on the turntable. A cylinder is arranged at the top of the dyeing tank. The telescopic rod of the cylinder is located inside the dyeing tank and is connected with a hook-and-loop fastener placement cage at the bottom. The dyeing tank is respectively connected with a dyeing liquid inlet pipeline and a dyeing liquid outlet pipeline arranged up and down. A circulation pump is arranged on the dyeing liquid outlet pipeline. The dyeing liquid outlet pipeline and the dyeing liquid inlet pipeline are connected with a heat exchanger. The heat exchanger is connected with a high-temperature steam pipeline and a low-temperature gas pipeline. The high-temperature steam pipeline is connected with a steam generator. A plurality of thermoelectric generator plates are successively connected in series on the outer wall of the heat exchanger. The thermoelectric generator plates are connected with a backup storage battery. The motor is connected with the backup storage battery. This device performs multiple heat preservation treatments on the outer surface of the dyeing tank, reduces heat loss, and strengthens safe production. However, this device has a large water consumption, uneven dyeing, and low color fastness. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-temperature dyeing device for hook-and-loop fasteners aiming at the above existing technical problems, with less water consumption, uniform dyeing, and high color fastness.

[0005] In view of this, the present utility model provides a high-temperature dyeing device for hook-and-loop fasteners, which includes a bracket and a dyeing tank on the bracket. The dyeing tank is provided with a feed port and a discharge port at its opening, and further includes: a stirring tank, which is arranged outside the area of the dyeing tank; a heater, the bottom of which is connected to the bottom of the stirring tank; a supercharger, which is arranged on the side wall of the dyeing tank and is connected to the heater; a shunt pipe, which is arranged on the side wall of the tank and is connected to the supercharger; a spraying pipe, which penetrates through the dyeing tank and is connected to the shunt pipe.

[0006] In this technical solution, the stirring tank mixes the dye and water and stirs them to form a dyeing agent. The stirred dyeing agent is heated by the heater, and then through the pressurization of the supercharger, the dyeing agent flows into the shunt pipe and enters the spraying pipe to spray and dye the hook-and-loop fasteners in the dyeing tank. The dyeing agent has improved color fastness after heating. The hook-and-loop fasteners enter the dyeing tank under the action of external traction, and the spraying pipe sprays the high-temperature dyeing agent on the hook-and-loop fasteners to achieve a uniform dyeing effect. The stirring tank is prior art and will not be elaborated.

[0007] In the above technical solution, further, the spraying pipe includes spraying heads, which are linearly arranged in an array along the length direction of the spraying pipe on the surface of the spraying pipe.

[0008] In this technical solution, two spraying pipes are symmetrically arranged up and down, and the spraying heads correspond to each other. The hook-and-loop fasteners pass through between the two spraying pipes, so that both the upper and lower surfaces of the hook-and-loop fasteners are sprayed. The spraying heads spray the dyeing agent concentratedly and uniformly on the hook-and-loop fasteners, achieving a uniform dyeing effect.

[0009] In the above technical solution, further, it further includes an extrusion assembly. The extrusion assembly includes a first mounting plate, which is arranged in the dyeing tank. Hydraulic cylinders are symmetrically arranged on both sides of the mounting plate. The hydraulic cylinders are sleeved with first springs. The output ends of the hydraulic cylinders are connected to a second mounting plate. Fixed blocks are symmetrically arranged on both sides of the second mounting plate. An extrusion roller is movably arranged between the two fixed blocks.

[0010] In this technical solution, two extrusion assemblies are symmetrically arranged up and down in the dyeing tank. The hook-and-loop fasteners pass through between the two extrusion rollers. The hydraulic cylinders assist in the conversion of the deformation amount of the first springs. The conversion of the deformation amount of the first springs squeezes the hook-and-loop fasteners through the extrusion rollers. When the hook-and-loop fasteners are sprayed with the dyeing agent, the extrusion assembly squeezes the hook-and-loop fasteners, so that the dyeing agent better penetrates into the interior of the hook-and-loop fasteners and squeezes out the excess dyeing agent.

[0011] In the above technical solution, further, it further includes an adjustment component. The adjustment component is arranged below the extrusion component. The adjustment component includes a sliding groove. The sliding groove is arranged on the side wall of the dyeing tank. One of the extrusion components is movably arranged in the sliding groove. An adjustment unit is arranged below the sliding groove. The adjustment unit adjusts the position of the extrusion component in the sliding groove.

[0012] In this technical solution, when the extrusion component moves upward, the two extrusion components approach each other, and the first spring is compressed. The amount of deformation released by the first spring increases, making the extrusion effect of the two extrusion components stronger. When the extrusion component moves downward, the two extrusion components move away from each other, the first spring is relaxed, and the amount of deformation released by the first spring decreases, making the extrusion effect of the two extrusion components weaker.

[0013] In the above technical solution, further, the adjustment unit includes a rotating shaft. The rotating shaft is movably arranged in the dyeing tank. The rotating shaft is coaxially and fixedly connected with an eccentric disk. The two eccentric disks are symmetrically arranged on the rotating shaft. One end of the rotating shaft passes through the side wall of the dyeing tank and is coaxially and fixedly connected with a crank wheel.

[0014] In this technical solution, when the crank wheel is rotated manually, the crank wheel drives the rotating shaft to rotate. The rotating shaft drives the eccentric disk to rotate. Due to the change in the diameter of the eccentric disk, when the extrusion component contacts the surface of the eccentric disk, the extrusion component moves up and down in the sliding groove. The adjustment unit adjusts the displacement of the extrusion component.

[0015] In the above technical solution, further, it further includes a recovery component. The recovery component includes a diversion hopper. The diversion hopper is fixedly arranged at the bottom of the tank. The bottom of the diversion hopper is connected with a diversion pipe. The other end of the diversion pipe is connected with a filter. The filter is connected with a heater.

[0016] In this technical solution, the sprayed dyeing agent and the extruded dyeing agent fall into the diversion hopper at the bottom of the dyeing tank. The diversion hopper diverts these dyeing agents into the diversion pipe. The dyeing agent flows along the diversion pipe into the filter. The filter filters out the impurities in the dyeing agent. The filtered dyeing agent enters the heater again for secondary utilization. The recovery component recovers and utilizes the excess dyeing agent, reducing waste.

[0017] In the above technical solution, further, it further includes an air flow fan. The air flow fans are linearly arranged in an array above the feed inlet and the discharge outlet. The air flow fans are all arranged in the same direction.

[0018] In this technical solution, the air flow fans accelerate the air flow in the dyeing tank. The sprayed fasteners are affected by the air pressure of the air flow, improving the color fastness.

[0019] The beneficial effects of the present utility model are:

[0020] 1. By setting up an extrusion component, after the hook-and-loop fastener is sprayed with dye, the extrusion component extrudes the hook-and-loop fastener, enabling the dyeing agent to better penetrate into the interior of the hook-and-loop fastener and squeezing out the excess dyeing agent.

[0021] 2. By setting up a recycling component, the excess dyeing agent is recycled, reducing waste.

[0022] 3. By setting up an air flow fan, the air flow fan accelerates the air flow in the dyeing tank. The hook-and-loop fastener that has been sprayed is affected by the air pressure of the air flow, improving the color fastness. BRIEF DESCRIPTION OF THE DRAWINGS
