Description

Technical Field

[0001] The utility model belongs to the technical field of flame-retardant fabric production, in particular to a production device for reducing flame-retardant color change of flame-retardant fabric. Background Art

[0002] Usually, the colors of protective workwear are mainly dark series such as gray and dark blue, and the dyes used for dyeing are mainly active series. This series of active dyes will change color obviously before and after flame retardant ammonia fumigation, and it is easy to cause uneven discoloration on the cloth surface, resulting in color spots and difficulty in repair, which will cause relatively large economic losses to manufacturers and cause particularly great trouble to clothing production. Flame retardant finishing of all-cotton knitted fabrics requires oxidation in an overflow machine, and the width will be first processed from flat width to rope processing. Therefore, an intermittent method is required for production. The dyed all-cotton knitted fabric is first rolled in a flat width for flame retardant drying, then cross-linked in an ammonia fumigation instrument, and then entered into an overflow machine in a rope form for oxidation, neutralization, and formaldehyde washing to complete the flame retardant protection function of the fabric. When knitting flame retardant khaki, gray, olive green and other sensitive colors, it is easy to have inconsistent color difference before and after, and transitional color defects, which seriously affect product quality. Therefore, it is necessary to reduce the production equipment of color change to cool it down to ensure that the temperature of the fabric quickly returns to a stable state after ammonia fumigation, but it still has the following disadvantages in actual use:

[0003] After the flame retardant fabric is fumigated with ammonia, the surface temperature of the fabric is relatively high. The fabric is cooled directly by passing through a drum with cooling water flowing inside. During the cooling process, the cooling water needs to be continuously passed through, and additional equipment for cooling the cooling water needs to be operated. The plant area occupied during operation is relatively large, and the equipment cost is relatively high.

[0004] After ammonia fumigation, flame-retardant fabrics need to be transported to cooling drums for cooling. After cooling, they are transported to the next processing equipment for processing. During the production and processing process, the cooling drums that the fabrics pass through are usually combined, the heat dissipation area that the fabrics pass through is limited, and the heat dissipation efficiency is not high enough. Utility Model Content

[0005] The utility model aims to provide a production device for reducing the flame retardant color change of flame retardant fabrics. By arranging a drum, a central rotating shaft, a fixing frame and an air inlet duct, the utility model solves the problem that in the work of cooling the flame retardant fabrics to prevent the color change after ammonia fumigation, the cooling water and the drum are required to cooperate with the equipment, the cost is high, the floor space is large, the fabric does not pass through the heat dissipation drum sufficiently, and the heat dissipation efficiency is not high enough.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a production device for reducing the flame retardant color change of flame retardant fabrics, comprising a drum, a central rotating shaft, a fixing frame and an air inlet tube, the inner wall of the drum is fixed with heat sinks in an annular array, the drum is provided with a central rotating shaft penetrating along the central axis, the two ends of the central rotating shaft are connected to the fixing frame for common rotation, the fixing frame is provided with air inlet tubes on both sides, the air inlet tubes are arranged at the end of the drum, when working, the drum is provided with a flame retardant ammonia fumigated dyed fabric to cool down, the central rotating shaft is driven to rotate when rotating, the flame retardant ammonia fumigated dyed fabric is cooled through its surface by the rotation of the drum, the central rotating shaft is supported on an external bracket by the fixing frame, air is blown into the drum through the structure in the air inlet tube, and the drum is cooled down faster.

[0008] Furthermore, fixed shafts are evenly fixed on the circumference of the central rotating shaft, and ends of all the fixed shafts away from the central rotating shaft are fixed on the inner wall of the drum, and the central rotating shaft is fixed to the drum via the fixed shafts.

[0009] Furthermore, the fixed frame includes a fixed plate and a movable hole. Fixed plates are provided at both ends of the drum. The bottom of the fixed plate is fixed on an external bracket. A movable hole is opened inside the fixed plate between the two air inlet tubes along the extension line of the central axis of the drum. The two ends of the central rotating shaft are respectively rotatably connected to the two fixed plates, and the fixed frame supports the central rotating shaft on the external bracket through the fixed plates.

[0010] Furthermore, a driving motor is fixed on the side of the fixed plate between the two air inlet cylinders away from the drum, a driving shaft is fixed on the output end of the driving motor, the driving shaft is inserted into the movable hole, and the end of the driving shaft away from the driving motor is fixed to the central rotating shaft.

[0011] Furthermore, the fixing frame also includes a roller, and the two short sides of the two fixing plates close to each other are rotatably connected to the roller, and the roller is arranged outside the outer circumference of the drum.

[0014] The utility model solves the problem that the flame retardant fabric needs cooling water and a drum to cooperate with each other in the work of cooling down and preventing color change after ammonia fumigation, which has high equipment cost and large floor space by arranging a drum, a central rotating shaft and an air inlet pipe. When the drum rotates, the internal fan is started, the internal fan draws in external air, and then blows it into the drum through the air inlet pipe. After the heat is dissipated by the heat sink fixed on the inner wall of the drum, the surface temperature of the drum is rapidly reduced, which speeds up the cooling efficiency of the drum for the flame retardant ammonia fumigated dyed fabric. Therefore, the flame retardant fabric does not need cooling water to cooperate in the work of cooling down and preventing color change after ammonia fumigation, and the equipment cost is lower and the floor space is smaller.

[0015] The utility model solves the problem that the fabric does not pass through the heat dissipation roller sufficiently and the heat dissipation efficiency is not high enough by arranging a roller, a central rotating shaft and a fixing frame. When the dyed fabric after flame-retardant ammonia fumigation is conveyed to the roller, it is guided to the surface of the roller by a rotating roller. After the fabric is guided to the surface of the roller, it is guided to the next processing equipment by another rotating roller for processing, so that the fabric can fit the roller well, the heat dissipation efficiency of the fabric is guaranteed, and the waste of the heat dissipation efficiency of the roller is reduced.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0025] See also Figure 1-5 The utility model is a production device for reducing the flame retardant color change of flame retardant fabrics, including a drum 1, a central rotating shaft 2, a fixing frame 3 and an air inlet 4. The inner wall of the drum 1 is fixed with heat sinks 101 in a circular array. When the drum 1 is working, the dyed fabric after flame retardant ammonia fumigation passes through its surface for cooling, so that the temperature of the dyed fabric passing through the surface of the drum 1 is quickly reduced to near normal temperature. The drum 1 increases the heat dissipation efficiency of the dyed fabric through the heat sink 101 therein. A central rotating shaft 2 is provided along the central axis of the drum 1. When the central rotating shaft 2 rotates, the drum 1 is driven to rotate. The two ends of the central rotating shaft 2 are connected to the fixing frame 3 for common rotation. The fixing frame 3 supports the drum 1 on an external supporting structure. Air inlet 4 is provided on both sides of the fixing frame 3. The air inlet 4 is provided at the end of the drum 1. Air is blown into the drum 1 through the structure in the air inlet 4 to cool the drum 1.

[0026] Specifically, fixed shafts 201 are evenly fixed on the circumference of the central rotating shaft 2 , and ends of all fixed shafts 201 away from the central rotating shaft 2 are fixed on the inner wall of the drum 1 , and the central rotating shaft 2 and the drum 1 are connected together through the fixed shafts 201 .

[0027] Furthermore, the fixing frame 3 includes a fixing plate 301 and a movable hole 302. The fixing plates 301 are provided at both ends of the drum 1. The inside of the fixing plate 301 between the two air inlet tubes 4 is provided with a movable hole 302 that passes through along the extension line of the central axis of the drum 1. The two ends of the central rotating shaft 2 are rotatably connected to the two fixing plates 301 respectively, and the central rotating shaft 2 is connected thereto through the fixing plate 301, and is movably connected to the drive shaft 203 through the movable hole 302.

[0028] Furthermore, a driving motor 202 is fixed on the side of the fixed plate 301 between the two air inlet tubes 4 away from the drum 1, and a driving shaft 203 is fixed on the output end of the driving motor 202. The driving shaft 203 is inserted into the movable hole 302, and the end of the driving shaft 203 away from the driving motor 202 is fixed to the central rotating shaft 2. The driving shaft 203 is driven to rotate by the power generated by the driving motor 202. When the driving shaft 203 rotates, the central rotating shaft 2 is driven to rotate. When the central rotating shaft 2 rotates, the drum 1 is driven to rotate.

[0029] Furthermore, the fixed frame 3 also includes a roller 303. The two short sides of the two fixed plates 301 close to each other are rotatably connected to the roller 303. The roller 303 is arranged on the outside of the outer peripheral surface of the drum 1. When the flame-retardant ammonia fumigated and dyed fabric is transported to the drum 1, it is guided to the surface of the drum 1 through a roller 303. After the surface of the drum 1 is cooled, it is guided to the next processing equipment for processing through another roller 303.

[0030] The operation process of this embodiment is as follows: during operation, when the flame-retardant ammonia fumigated dyed fabric is conveyed onto the drum 1, it is guided onto the surface of the drum 1 by a rotating roller 303. After the fabric is guided onto the surface of the drum 1, it is guided to the next processing equipment by another rotating roller 303. When the fabric is guided onto the surface of the drum 1, the drum 1 dissipates heat through the heat sink 101 on its inner wall, thereby accelerating the heat dissipation efficiency of the fabric. At the same time, the driving motor 202 is started, and the driving shaft 203 is driven to rotate by the power generated by the driving motor 202. When the driving shaft 203 rotates, the central rotating shaft 2 is driven to rotate. When the central rotating shaft 2 rotates, it is fixed to the drum 1 by the fixed shaft 201 on the peripheral side of the central rotating shaft 2, thereby driving the drum 1 to rotate, so that the peripheral side of the drum 1 continuously circulates to cool the flame-retardant ammonia fumigated dyed fabric. Specific embodiment 2

[0031] See also Figure 1 , 2 5. On the basis of the specific embodiment 1, mounting plates 401 are fixed on the outer circumferential surfaces of the two air inlet tubes 4, and mounting holes 402 are formed through the two corners of the mounting plates 401 away from the air inlet tube 4. Internal fixing rods 403 are fixed in a circular array on the inner wall of the air inlet tube 4, and internal fans 404 are fixed at the ends of the internal fixing rods 403 close to each other. The air inlet tube 4 is installed through the mounting holes 402 on the mounting plates 401, and the internal fans 404 are fixed therein through the internal fixing rods 403. Air is drawn into the air inlet tube 4 through the internal fans 404 and then transported to the drum 1.

[0032] The operation process of this embodiment is as follows: during operation, when the drum 1 rotates, the internal fan 404 is started, the internal fan 404 draws in external air, and then blows it into the drum 1 through the air inlet pipe 4. After the heat is dissipated by the heat sink 101 fixed on the inner wall of the drum 1, the surface temperature of the drum 1 is rapidly reduced, thereby accelerating the cooling efficiency of the drum 1 on the dyed fabric after flame-retardant ammonia fumigation.
