Description
Technical Field
[0001] This application relates to the technical field, and particularly to a textile fabric drying and shaping device. Background Art
[0002] With the continuous development of the social economy and the increasing improvement of the scientific and technological level, the textile industry in China is also booming. As a device for drying and shaping fabrics after fabric printing and dyeing, the fabric drying and shaping device can make the shrinkage rate of the fabric stable after drying and reduce the occurrence of fabric decolorization after washing, so it plays an important role in the textile industry.
[0003] There is a fabric drying and shaping device in the prior art, which includes a machine body. A drying chamber is opened in the machine body, and a plurality of conveying rollers are also arranged in the drying chamber. A drying mechanism is also arranged on the machine body. The drying mechanism is used to draw external air into itself and heat the drawn air and then introduce it into the drying chamber. A winding mechanism is also arranged on the machine body. The winding mechanism is located at one end of the machine body and is used to wind the dried fabric. When in use, the conveying rollers and the winding mechanism transport the fabric into the drying chamber. During this process, the drying mechanism heats the external gas and introduces it into the drying chamber to dry the fabric, and then the winding mechanism leads the dried fabric out of the drying chamber and winds it up.
[0004] In view of the above related technologies, since the surface of the fabric still has a relatively high temperature after being dried by the drying mechanism in the prior art, and in the prior art, after the fabric is dried, the winding mechanism drives the fabric to directly enter the external normal-temperature air, causing the fabric to cool naturally. However, the temperature difference between the drying chamber and the outside is too large, which makes the fabric prone to rebound and shrinkage when cooling in the normal-temperature air, thus resulting in a reduction in fabric quality. Utility Model Content
[0005] In order to reduce the probability of the fabric rebounding and shrinking during cooling, this application provides a textile fabric drying and shaping device.
[0006] A textile fabric drying and shaping device provided by this application adopts the following technical solutions:
[0007] A textile fabric drying and shaping device includes a machine body. A drying mechanism for drying the fabric is arranged on the machine body. A drying chamber is opened in the machine body, and a pre-cooling chamber is also arranged in the machine body. One end of the pre-cooling chamber is communicated with the drying chamber. The fabric enters the pre-cooling chamber through the drying chamber and exits from the other end of the pre-cooling chamber. A ventilation pipe is also arranged on the machine body. One end of the ventilation pipe is communicated with the bottom end of the drying chamber, and the other end of the ventilation pipe is communicated with the pre-cooling chamber. An exhaust fan is also arranged on the ventilation pipe.
[0008] By adopting the above technical solution, compared with the prior art where the dried fabric is directly led to the outside air for natural cooling, in this application, by setting up an air pipe and an exhaust fan, the exhaust fan can extract the gas that has exchanged heat with the fabric at the bottom of the drying chamber and cooled down from the drying chamber, and then introduce it into the pre-cooling chamber through the air pipe, so that the cooled gas can come into contact with the fabric. The temperature of the gas after heat exchange is lower than that in the drying chamber and higher than the outside temperature. Thus, the gas after heat exchange can pre-cool the fabric, thereby reducing the probability of rebound shrinkage caused by too large a temperature difference when the fabric contacts the outside air, ensuring the quality of the fabric after drying, and at the same time, the gas in the drying chamber can be reused.
[0009] Preferably, a leveling mechanism is further provided on one side of the drying chamber close to the pre-cooling chamber. The leveling mechanism includes a placement rack and leveling rollers. The placement rack is connected to the inner wall of the drying chamber and is used for placing the fabric. The bottom end of the leveling roller contacts the top wall of the fabric.
[0010] By adopting the above technical solution, the setting of the leveling mechanism enables the leveling roller to abut against the top wall of the dried fabric, and the leveling roller and the placement rack cooperate with each other to level the dried fabric, thereby reducing the probability of wrinkles in the dried fabric and effectively ensuring the quality of the fabric after drying.
[0011] Preferably, the leveling mechanism further includes a mounting rack and a driving component. The leveling roller is arranged on the mounting rack. The mounting rack is slidably connected to the machine body. The driving component is used to drive the mounting rack to slide along its own sliding direction.
[0012] By adopting the above technical solution, the setting of the driving component enables relevant personnel to drive the mounting rack to drive the leveling roller to displace through the driving component, thereby changing the abutting effect of the leveling roller on the fabric, and then adjusting the leveling effect on the fabric, effectively facilitating the control of the leveling effect of the fabric by relevant personnel. At the same time, relevant personnel can also adjust the distance between the leveling roller and the mounting rack through the driving component to adapt to fabrics of different thicknesses, increasing the scope of application of this application.
[0013] Preferably, a buffer rack is further provided on the mounting rack. The leveling roller is rotatably connected to the buffer rack. The buffer rack is slidably connected to the mounting rack. The sliding direction of the buffer rack is the same as the sliding direction of the mounting rack. A buffer spring is further arranged between the buffer rack and the mounting rack. The two ends of the buffer spring respectively abut against the buffer rack and the mounting rack.
[0014] By adopting the above technical solution, the setting of the buffer frame enables relevant personnel to control the displacement amount of the mounting frame when the leveling roller contacts the fabric, thereby controlling the pressure when the leveling roller abuts against the fabric. At the same time, it can also reduce the probability of collision and damage between the leveling roller and the placement frame, playing a buffering role.
[0015] Preferably, a transition box is further provided at the bottom end of the machine body. The ventilation pipe is communicated with the drying cavity via the transition box, and a filter screen is further provided at one end of the ventilation pipe communicated with the transition box.
[0016] By adopting the above technical solution, the setting of the filter screen can effectively block some sundries in the drying cavity, thereby reducing the probability of the sundries in the drying cavity being sucked into the machine by the exhaust fan, effectively ensuring the service life of the exhaust fan, and at the same time reducing the probability of the sundries passing through the ventilation pipe to the pre-cooling cavity.
[0017] Preferably, a storage box with an open upper end is further provided in the transition box. The storage box is slidably connected to the transition box and is located below the filter screen.
[0018] By adopting the above technical solution, the setting of the storage box enables relevant personnel to pull out the storage box after the equipment in this application is used, thereby facilitating the cleaning of the garbage in the transition box and facilitating the operation of relevant personnel.
[0019] Preferably, a plurality of guide rollers are further provided in the pre-cooling cavity. The guide rollers are arranged staggeredly along the height direction of the machine body, and each guide roller is rotatably connected to the machine body.
[0020] By adopting the above technical solution, the setting of the guide rollers effectively prolongs the residence time of the fabric in the pre-cooling box, thereby improving the pre-cooling effect on the fabric and reducing the probability of the fabric shrinking due to insufficient pre-cooling after passing to the outside.
[0021] Preferably, a plurality of ventilation hoods are further provided in the pre-cooling cavity. The plurality of ventilation hoods are respectively located on the upper and lower sides of the fabric in the pre-cooling cavity. A plurality of ventilation holes are opened on one side of each ventilation hood close to the fabric, and the ventilation pipe is communicated with each ventilation hood.
[0022] By adopting the above technical solution, the setting of the ventilation hoods enables the pre-cooling gas introduced through the ventilation pipe to blow to the upper and lower surfaces of the fabric through the two ventilation hoods, thereby improving the pre-cooling effect on the fabric and reducing the probability of the fabric shrinking due to insufficient pre-cooling after passing to the outside.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The arrangement of the vent pipe and the exhaust fan enables the exhaust fan to extract the gas cooled by heat exchange with the fabric at the bottom end of the drying chamber from the drying chamber, and pass it into the pre-cooling chamber through the vent pipe, so that the cooled gas can contact the fabric, and the gas after heat exchange can pre-cool the fabric. This reduces the probability of rebound shrinkage of the fabric caused by excessive temperature difference after contacting the outside air, ensures the quality of the fabric after drying, and can also recycle the gas in the drying chamber.
[0025] 2. The arrangement of the leveling mechanism enables the leveling roller to abut against the top wall of the fabric after drying, and the leveling roller and the placement rack cooperate to level the fabric after drying, thereby reducing the probability of wrinkles in the fabric after drying and effectively ensuring the quality of the fabric after drying.
[0026] 3. The arrangement of the guide roller effectively extends the residence time of the fabric in the pre-cooling box, thereby improving the pre-cooling effect on the fabric and reducing the probability of shrinkage of the fabric due to insufficient pre-cooling after passing to the outside.
