Description

Technical Field

[0001] This utility model relates to the field of sofa fabric dyeing equipment technology, and in particular to a dyeing device for precise temperature control of sofa fabric dyeing. Background Technology

[0002] With the development of the textile industry and the increasing demand for personalized home decoration from consumers, sofa fabric, as an important home decoration material, is receiving more and more attention from the market for its diverse colors and patterns. The processing of sofa fabric requires dyeing equipment.

[0003] For example, in the prior art (a dyeing device for a sofa fabric that facilitates drainage disclosed in prior patent application number: CN202020129380.X), although the dyeing device has an auxiliary drainage structure that can speed up the drainage by lowering the iron and pressing it onto the sofa fabric, when the iron is pressed down onto the sofa fabric, the large friction between the bottom surface of the iron and the upper surface of the sofa fabric causes the sofa fabric being conveyed to the right to be pulled and torn, thereby reducing the reliability of the dyeing device during drainage. In addition, the dyeing box in the existing dyeing device lacks an effective anti-settling structure, which makes it easy for the dye to settle inside the dyeing box, thus affecting the dyeing effect on the sofa fabric. Utility Model Content

[0004] This disclosure relates to a precision temperature-controlled dyeing apparatus for sofa fabric. Through the design of the water-squeezing mechanism, the friction between the upper surface of the sofa fabric and the outer circumference of the water-squeezing roller is extremely small, effectively preventing tearing caused by excessive frictional resistance. This significantly improves the stability and reliability of the dyeing apparatus during draining, ensuring smooth dyeing operations and stable product quality output. Furthermore, the anti-sedimentation mechanism effectively prevents dye sedimentation inside the dyeing chamber, significantly improving the dyeing quality and uniformity of the sofa fabric.

[0005] In a first aspect, this disclosure provides a precision temperature-controlled dyeing apparatus for fabric dyeing, specifically comprising: a dyeing chamber, a support frame plate mounted on the upper surface of the dyeing chamber, and a guide roller rotatably connected to the upper surface of the support frame plate; a heating pipe mounted on the lower side inside the dyeing chamber, and a liquid temperature sensor mounted on the rear side wall inside the dyeing chamber; a controller mounted on the front surface of the dyeing chamber; two fabric roller frames symmetrically mounted on the left side of the upper surface of the support frame plate, with fabric rollers placed on the upper ends of the two fabric roller frames; a pressing mechanism mounted on the left side of the upper surface of the support frame plate, and a support plate fixedly mounted on the right side of the upper surface of the support frame plate, with a squeezing mechanism provided on the upper surface of the support plate; and an anti-sedimentation mechanism provided at the lower end inside the dyeing chamber.

[0006] In at least some embodiments, a frame-shaped flow-limiting plate is provided at the edge of the upper surface of the support frame plate; a polytetrafluoroethylene plate is fixedly connected to the middle side of the upper surface of the support frame plate.

[0007] In at least some embodiments, the pressing mechanism includes a U-shaped support plate, a first electric cylinder, a lifting plate, and a pressing roller. The U-shaped support plate is fixedly installed on the left side of the upper end face of the support frame plate, and the first electric cylinder is fixedly installed on the upper end face of the U-shaped support plate. The telescopic rod of the first electric cylinder passes through the top of the U-shaped support plate, and the lower end of the telescopic rod of the first electric cylinder is fixedly connected to the lifting plate. The upper end face of the lifting plate is provided with four vertical guide rods that pass through the top of the U-shaped support plate, and the bottom of the lifting plate is rotatably connected to the pressing roller.

[0008] In at least some embodiments, the dewatering mechanism includes a U-shaped support frame, a second electric cylinder, a lifting plate, and a dewatering roller. The U-shaped support frame is fixedly installed on the upper surface of the support plate and is located outside the polytetrafluoroethylene plate. The second electric cylinder is fixedly installed on the top surface of the U-shaped support frame, and the telescopic rod of the second electric cylinder passes through the top of the U-shaped support frame. The lower end of the telescopic rod of the second electric cylinder is fixedly connected to the lifting plate, and a sliding guide rod passing through the top of the U-shaped support frame is provided at each of the four corners of the upper surface of the lifting plate. The dewatering roller is rotatably connected to the bottom of the lifting plate in a uniform manner.

[0009] In at least some embodiments, the anti-sedimentation mechanism includes stirring shafts, drive rods, a drive motor, and sprockets. There are six stirring shafts, each externally connected to a sealing bushing fixed to the bottom surface of the dyeing chamber. All six stirring shafts penetrate the bottom of the dyeing chamber. Each stirring shaft has a stirring blade fixedly mounted on its upper external side, and a first bevel gear fixedly mounted at its lower end. There are two drive rods, both rotatably connected to the bottom of the dyeing chamber. Each drive rod has a sprocket fixedly mounted on its right end, and the two sprockets are connected by a chain drive. Each drive rod has two second bevel gears fixedly mounted externally, and the four second bevel gears mesh with the four first bevel gears respectively. The drive motor is fixedly mounted at the bottom of the dyeing chamber, and the right end of the drive motor's shaft is fixedly connected to the left end of the front drive rod.

[0010] This invention provides a precise temperature-controlled dyeing device for dyeing sofa fabrics, which has the following beneficial effects:

[0011] 1. By setting up the water-squeezing mechanism, during the dyeing process, the telescopic rod of the second electric cylinder can be controlled to extend downward, thereby moving the lifting plate and the water-squeezing roller downward, squeezing the dyed sofa fabric downward onto the upper surface of the polytetrafluoroethylene plate. Since the friction between the upper surface of the sofa fabric and the outer circumference of the water-squeezing roller is extremely small, and the upper surface of the polytetrafluoroethylene plate also has low friction characteristics, the tearing of the sofa fabric caused by excessive frictional resistance is effectively prevented. This significantly improves the stability and reliability of the dyeing device during the draining process, and effectively ensures the smooth progress of the dyeing operation and the stable output of product quality.

[0012] 2. By setting up an anti-sedimentation mechanism, the drive motor can be started, driving one driving rod on the front, two sprockets, and one driving rod on the rear to rotate synchronously. Then, six second bevel gears drive six first bevel gears and six stirring shafts to rotate, thereby driving six stirring blades to stir. This effectively avoids the phenomenon of dye sedimentation inside the dyeing box and significantly improves the dyeing quality and uniformity of the sofa fabric.

[0013] 3. During the dyeing process, the heating pipes can be activated to heat the dye inside the dyeing chamber. Then, the temperature of the dye inside the dyeing chamber is monitored in real time by a liquid temperature sensor, and the temperature value is transmitted to the controller. The controller can precisely control the temperature of the dye inside the dyeing chamber by setting a preset temperature value, so that the temperature of the dye inside the dyeing chamber is kept within a certain range, which effectively improves the stability and consistency of dyeing, thereby improving the dyeing quality of the sofa fabric.

[0029] This utility model proposes a precise temperature-controlled dyeing device for sofa fabric dyeing, comprising: a dyeing chamber 1, a support frame plate 101 mounted on the upper surface of the dyeing chamber 1, and a guide roller 105 rotatably connected to the upper surface of the support frame plate 101; a heating tube 106 mounted on the lower side inside the dyeing chamber 1, and a liquid temperature sensor 107 mounted on the rear side wall inside the dyeing chamber 1. Multiple liquid temperature sensors 107 can be used to further improve the accuracy of dye temperature control. The front of the dyeing chamber 1... A controller 103 is installed on the end face; two sofa fabric roller frames 104 are symmetrically installed on the left side of the upper end face of the support frame plate 101, and sofa fabric rollers are placed on the upper end of the two sofa fabric roller frames 104; a pressing mechanism 2 is installed on the left side of the upper end face of the support frame plate 101, and a support plate 108 is fixedly installed on the right side of the upper end face of the support frame plate 101, and a squeezing mechanism 3 is provided on the upper end face of the support plate 108; an anti-settling mechanism 4 is provided at the lower end of the inside of the dyeing box 1 to prevent the dye inside the dyeing box 1 from settling.

Polytetrafluoroethylene is a polymer material with unique low friction properties, so it can reduce the frictional resistance generated between the lower surface of the sofa fabric and the upper surface of the polytetrafluoroethylene plate 109.

[0031] The pressing mechanism 2 includes a U-shaped support plate 201, a first electric cylinder 202, a lifting plate 203, and a pressing roller 204. The U-shaped support plate 201 is fixedly installed on the left side of the upper end face of the support frame plate 101, and the first electric cylinder 202 is fixedly installed on the upper end face of the U-shaped support plate 201. The telescopic rod of the first electric cylinder 202 passes through the top of the U-shaped support plate 201, and the lower end of the telescopic rod of the first electric cylinder 202 is fixedly connected to the lifting plate 203. The upper end face of the lifting plate 203 is provided with four vertical guide rods that pass through the top of the U-shaped support plate 201, and the bottom of the lifting plate 203 is rotatably connected to the pressing roller 204. Through the setting of the pressing mechanism 2, it is used to move the squeezing mechanism 3 downward to perform squeezing work.

[0032] The dewatering mechanism 3 includes a U-shaped support frame 301, a second electric cylinder 302, a lifting plate 303, and a dewatering roller 304. The U-shaped support frame 301 is fixedly installed on the upper surface of the support plate 108 and is located outside the polytetrafluoroethylene plate 109. The second electric cylinder 302 is fixedly installed on the top surface of the U-shaped support frame 301, and the telescopic rod of the second electric cylinder 302 passes through the top of the U-shaped support frame 301. The lower end of the telescopic rod of the second electric cylinder 302 is fixedly connected to... The lifting plate 303 has a sliding guide rod at each of the four corners of its upper surface, which passes through the top of the U-shaped support frame 301. The bottom of the lifting plate 303 is uniformly rotatably connected to the water-squeezing roller 304. The second electric cylinder 302, the first electric cylinder 202, the heating pipe 106, and the liquid temperature sensor 107 are all electrically connected to the controller 103. The water-squeezing mechanism 3 is used to squeeze out excess water from the dyed sofa fabric, thereby improving the subsequent drying efficiency.

[0033] Example 2, based on Example 1, such as Figure 2 and Figure 4 As shown, the anti-sedimentation mechanism 4 includes stirring shafts 401, driving rods 402, a drive motor 403, and a sprocket 404. There are six stirring shafts 401, and each stirring shaft 401 is rotatably connected to a sealing bushing fixed to the bottom end face of the dyeing chamber 1. All six stirring shafts 401 penetrate the bottom of the dyeing chamber 1. A stirring blade is fixedly installed on the upper side of each stirring shaft 401, and a first bevel gear is fixedly installed at the lower end of each stirring shaft 401. There are two driving rods 402, and both driving rods 402 are rotatably connected to the bottom of the dyeing chamber 1. Furthermore, a sprocket 404 is fixedly installed on the right end of each drive rod 402, and the two sprockets 404 are connected by chain drive. Two second bevel gears are fixedly installed on the outside of each drive rod 402, and the four second bevel gears mesh with the four first bevel gears respectively. The drive motor 403 is fixedly installed at the bottom of the dyeing box 1, and the right end of the shaft of the drive motor 403 is fixedly connected to the left end of the front drive rod 402. Through the setting of the anti-sedimentation mechanism 4, the phenomenon of dye sedimentation inside the dyeing box 1 can be effectively avoided, thereby improving the dyeing quality and uniformity of the sofa fabric.

[0034] The working principle of this embodiment is as follows: When in use, dye is first added to the dyeing box 1, and then the drive motor 403 is started by the controller 103, which drives the front drive rod 402, two sprockets 404 and the rear drive rod 402 to rotate synchronously. Then, the six second bevel gears drive the six first bevel gears and the six stirring shafts 401 to rotate, thereby driving the six stirring blades to perform stirring motion.

[0035] Next, the heating element 106 is started by the controller 103, and the dye inside the dyeing chamber 1 is heated by the heating element 106. Then, the temperature of the dye inside the dyeing chamber 1 is monitored in real time by the liquid temperature sensor 107, and the temperature value is transmitted to the controller 103. The controller 103 uses the preset temperature value to precisely control the temperature of the dye inside the dyeing chamber 1, so that the temperature of the dye inside the dyeing chamber 1 is kept within a certain range.

[0036] Then, the fabric roller is placed on the upper part of the two fabric roller frames 104. Next, the fabric wound on the fabric roller is pulled to the right and passes through the bottom of the lower pressure roller 204, the upper part of the guide roller 105 and the bottom of the squeezing roller 304 in sequence. Then, the telescopic rod of the first electric cylinder 202 is controlled to extend downward, moving the lifting plate 203 and the lower pressure roller 204 downward, so that the lower pressure roller 204 carries the fabric into the dyeing box 1, so that the fabric is soaked in dye and dyed. Then, the fabric is conveyed to the right by the external conveying equipment, thus completing the dyeing of the fabric.

[0037] During the dyeing process, the telescopic rod of the second electric cylinder 302 is controlled to extend downward, thereby moving the lifting plate 303 and the squeezing roller 304 downward, squeezing the dyed sofa fabric downward onto the upper surface of the polytetrafluoroethylene plate 109. Since the upper surface of the sofa fabric has a small frictional force with the outer peripheral surface of the squeezing roller 304, and the upper surface of the polytetrafluoroethylene plate 109 also has a small frictional force, the tearing of the sofa fabric conveyed to the right is effectively avoided.
