Description

Technical Field

[0001] This utility model relates to the technical field of fabric dryers, specifically a fabric dryer. Background Technology

[0002] In the processing and production of clothing products such as knitted pants and loungewear, fabric drying is an indispensable and important step. Its drying effect directly affects the quality, performance and production efficiency of the products. Knitted fabrics and loungewear materials are usually made of pure cotton, spandex, chemical fiber blends and other materials. These fabrics have the characteristics of being soft, moisture-absorbing and elastic, but at the same time, they also place higher demands on drying equipment.

[0003] Currently, Chinese patent CN221811462U discloses a textile fabric drying mechanism, including a drying chamber, a dryer, and a textile fabric. The dryer is installed at the lower end of one side of the drying chamber. This invention, through the setting of three guide rollers and hot air pipes, etc., allows the dryer to blow hot air through the hot air pipes during use. The three guide rollers guide the textile fabric in an M-shape inside the drying chamber, while the three hot air pipes simultaneously dry the upper and lower surfaces of the textile fabric. This ensures efficient and uniform drying of the textile fabric, effectively avoiding problems such as uneven distribution of hot air in the drying chamber, resulting in insufficient hot air volume on some parts of the fabric, leading to incomplete drying and affecting the softness and fluffiness of the fabric, and insufficient temperature control precision of the hot air during the drying process, which may damage the fabric fibers and affect its service life.

[0004] The aforementioned textile drying mechanism still has some problems in use. Although it can effectively avoid the problem of insufficient hot air volume in some parts of the fabric due to uneven distribution of hot air in the drying chamber, when drying thicker fabrics, heat transfer is difficult to penetrate into the fabric quickly and evenly. This means that the surface of the fabric may appear to be dry, but there may be a lot of moisture inside. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This embodiment provides a fabric dryer, including a drying chamber 100. The left side of the drying chamber 100 has an inlet 107 for the fabric to enter the chamber, and the right side of the drying chamber 100 has an outlet 102 for the dried fabric to leave. Three sets of guide rollers 106 are rotatably connected inside the drying chamber 100. The three sets of guide rollers 106 are arranged in an inverted V shape. The left side of the drying chamber 100 is equipped with a squeezing component for squeezing the fabric to reduce its moisture content. The bottom of the drying chamber 100 is equipped with a drying component for supplying hot air into the drying chamber 100 to dry the fabric.

[0029] The extrusion assembly includes a fixed plate 201 fixedly installed in the upper left inner cavity of the drying chamber 100 and arranged along its width. A rotating roller 203 is rotatably connected inside the drying chamber 100 and below the fixed plate 201. An extrusion roller 202 is arranged below the fixed plate 201. Bearings 204 are rotatably sleeved at both ends of the extrusion roller 202. Connecting rods 206 are fixedly connected to the tops of the two sets of bearings 204. The tops of the two sets of connecting rods 206 extend upward through the corresponding side ends of the fixed plate 201. An elastic pushing member is provided on the surface of the connecting rod 206 located between the bearings 204 and the fixed plate 201 to push the extrusion roller 202 downward so as to cooperate with the rotating roller 203 to extrude the fabric. An adjusting member is provided above the fixed plate 201 for pulling the connecting rod 206 upward so as to adjust the height of the extrusion roller 202.

[0030] The drying assembly includes a dryer 304 disposed at the bottom of the drying chamber 100. A fixing ring 303 is fitted on the outer circumference of the dryer 304. The top of the fixing ring 303 is fixedly connected to the bottom surface of the drying chamber 100. The air outlet of the dryer 304 is connected to a conveying pipe 305. The end of the conveying pipe 305 extends upward into the drying chamber 100 and is located between three sets of guide rollers 106. The end of the conveying pipe 305 located between the three sets of guide rollers 106 is connected to a hollow block 306. Several sets of air jet pipes 30 are respectively connected to the top of both sides of the hollow block 306. 7. The air outlets of the jet pipes 307 on both sides are inclined upwards to the corresponding sides. Through the arrangement of the extrusion assembly and the drying assembly, the elastic pusher pushes the extrusion roller 202 downwards, which works with the rotating roller 203 to extrude the fabric, thereby removing most of the moisture from the fabric in advance. At the same time, the hot air generated by the dryer 304 enters the hollow block 306 through the conveying pipe 305. The jet pipes 307 on both sides of the hollow block 306 are inclined upwards to the opposite sides, so that the hot air is sprayed onto the fabric surface, thereby allowing the hot air to penetrate into the fabric quickly and evenly, avoiding localized insufficient drying.

[0031] The elastic pusher includes two sets of springs 205, which are respectively sleeved on the surface of the connecting rod 206. The two ends of the two sets of springs 205 contact the bottom of the fixed plate 201 and the top of the bearing 204, respectively. Through the setting of the elastic pusher, the two sets of springs 205 act on the two ends of the extrusion roller 202, which can automatically adjust the extrusion pressure according to the fabric thickness, avoiding uneven dehydration caused by uneven fabric. At the same time, the elastic thrust of the springs 205 makes the extrusion roller 202 and the rotating roller 203 form a flexible extrusion surface, reducing damage to the fabric fibers. It is suitable for various types of fabrics.

[0032] The adjusting component includes a connecting plate 200 fixedly connected to the top of the two sets of connecting rods 206. A hand-tightening bolt 207 is threadedly connected to the middle of the connecting plate 200. The end thread of the hand-tightening bolt 207 passes through the connecting plate 200 and abuts against the top of the fixed plate 201. Through the setting of the adjusting component, the combination structure of the hand-tightening bolt 207 and the connecting plate 200 allows the operator to adjust the height of the extrusion roller 202 by hand, improving the efficiency of parameter adjustment in the production process. Furthermore, by rotating the hand-tightening bolt 207, the extrusion roller 202 can be moved up and down, and the extrusion force can be precisely controlled to meet the dewatering process requirements of different fabrics.

[0033] A U-shaped plate 300 is fixedly connected inside the drying chamber 100 and below the rotating roller 203. The two ends of the U-shaped plate 300 extend upward to both sides of the rotating roller 203. A drain pipe 105 is inserted into the rear surface of the drying chamber 100. The inner cavity of the drain pipe 105 is connected to the inner cavity of the U-shaped plate 300. The U-shaped plate 300 is set around the bottom of the rotating roller 203, which can accurately catch the water dripping during the squeezing process and prevent liquid splashing and contamination of the fabric. The drain pipe 105 is directly connected to the inner cavity of the U-shaped plate 300 to ensure that the squeezed water is discharged in time and to avoid water accumulation in the chamber affecting the stability of the equipment operation.

[0034] The dryer 304 has a steam-water separator 302 connected to its suction end, and a suction pipe 301 connected to the input end of the steam-water separator 302. The other end of the suction pipe 301 is bent upward and extends into the inner cavity of the U-shaped plate 300. Through the suction pipe 301, the suction pipe 301 penetrates into the inner cavity of the U-shaped plate 300 to draw in humid and hot air. After being separated by the steam-water separator 302, the air is recycled, reducing the heat loss of the dryer 304. At the same time, the separated dry air returns to the drying cycle, reducing the risk of water vapor condensation in the pipe and preventing internal corrosion of the equipment.

[0035] Among them, the steam-water separator 302 is a well-known technical means in the art. For its specific working principle and structure, please refer to the steam-water separator 302 body in a heating drying device with publication number CN222317478U. Other details will not be elaborated here.

[0036] The top of the drying chamber 100 is open 104, and a lid 101 is provided on the top of the drying chamber 100. A frame 103 is provided at the bottom of the drying chamber 100 to support the drying chamber 100. The open 104 on the top of the drying chamber 100 makes it easy for the staff to open the lid 101 and directly access the internal guide rollers 106, squeeze rollers 202 and other components, which makes it easy to wrap the fabric around the surface of the guide rollers 106. At the same time, it is easy to clean the inside of the drying chamber 100 and the surfaces of the guide rollers 106 and squeeze rollers 202.

[0037] Working principle;

[0038] First, the fabric enters the drying chamber 100 through the feed inlet 107 on the left side. It passes between the extrusion roller 202 and the rotating roller 203. The operator removes the cover 101. Then, through the opening 104, the end of the fabric passes around the three sets of guide rollers 106 arranged in an inverted V shape, forming an S-shaped movement path inside the drying chamber 100. It then passes out through the discharge outlet 102 and is finally connected to the winding equipment. The cover 101 is then placed over the opening 104 of the drying chamber 100 to close the opening 104.

[0039] At this time, the dryer 304 is turned on. The hot air generated by the dryer 304 enters the hollow block 306 through the conveying pipe 305, and then is ejected from the jet pipes 307 on both sides of the hollow block 306. The tilt angle of the jet pipes 307 can make the hot air act evenly on the fabric surface, improving the drying efficiency.

[0040] Then, the winding equipment is turned on to wind up the fabric. At the same time, the extrusion roller 202 is continuously pushed downward under the action of the spring 205, thus working closely with the rotating roller 203 to squeeze the fabric and effectively reduce the moisture content in the fabric.

[0041] Furthermore, the squeezed water will drip into the U-shaped plate 300 and then be discharged from the drying oven 100 through the drain pipe 105;

[0042] When the dryer 304 is running, the hot and humid air in the U-shaped plate 300 is drawn into the steam-water separator 302 through the suction pipe 301. The hot and humid air undergoes gas-liquid separation in the steam-water separator 302. The separated dry air returns to the suction end of the dryer 304, mixes with the newly generated hot air, and is then circulated back into the drying chamber 100 to form a hot air circulation. This can recover heat and reduce energy consumption.

[0043] When the extrusion pressure needs to be adjusted, simply rotate the hand-tightening bolt 207. Pushing the connecting plate 200 upward will drive the connecting plate 200 and the connecting rod 206, causing the extrusion roller 202 to rise and reduce the extrusion pressure; conversely, the extrusion roller 202 will fall and the extrusion pressure will increase.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
