Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment, and in particular to a drying machine for imitation wax printed fabrics. Background Technology

[0002] Imitation wax printing is a type of rotary screen printing process that requires good penetration to make the colors of the front and back of the fabric similar. Because the reverse side of the fabric also contains a lot of dye, it cannot have any contact with the rollers when it first enters the dryer. It can only come into contact with the rollers when the surface is dried to the point that it is basically free of dye. Therefore, the first layer of fabric in this type of dryer is suspended.

[0003] Chinese utility model patent No. 202120278057.3 discloses a wax-printed fabric drying oven, which consists of several drying oven units connected in series along the production line. Each drying oven unit has a first upper air duct and a first lower air duct horizontally arranged on its upper inner side; a second upper air duct horizontally arranged in the middle of the unit; and a third upper air duct horizontally arranged in the lower part. The air outlets of the first upper air duct and the first lower air duct are opposite each other. An upper fabric channel is formed between the first and first lower air ducts; a middle fabric channel is formed between the second and third upper air ducts; and a lower fabric channel is formed between the third upper air duct and the inner bottom wall of the drying oven unit. During operation, only fabric with wax-printed pigments on its front side enters the drying oven through the inlet and passes through the upper, middle, and lower fabric channels sequentially, finally exiting through the outlet. However, this structure has the following problems in actual production:

[0004] 1) The machine speed during operation should not be too fast. If the machine speed is too fast, the fabric surface will be too wet and will contaminate the return roller, causing color dragging. The upper fabric channel should not be too long either, as the fabric tension will be too high if it is too long.

[0005] 2) Because the fabric in the upper fabric channel is suspended in the middle and hangs down, the distance between the upper and lower air outlets cannot be too small. If the distance between the air nozzle and the fabric surface is too large, the drying efficiency will be low.

[0006] 3) Because the fabrics leaving the drying room at the end still need to retain a certain moisture content, and the drying capacity of the middle and lower fabric channels is more than sufficient, only some air vents can be closed, resulting in a waste of effective resources.

[0007] 4) During the drying process, the hot water vapor in the middle and lower fabric channels moves upward, resulting in high humidity in the upper part of the dryer, which is not conducive to drying the first layer of fabric.

[0008] Given the shortcomings of existing wax-printed fabric drying rooms, there is an urgent need to improve them in order to increase drying efficiency and save energy consumption. Utility Model Content

[0009] The purpose of this invention is to provide a drying machine for imitation wax printed fabrics.

[0010] The technical solution to achieve the purpose of this utility model is: a wax-printed fabric drying machine, which includes a drying chamber body, wherein the drying chamber body is composed of several drying chamber units connected in series along the production line direction. Within the drying chamber body, a first blowing unit is horizontally arranged in the lower middle part of each drying chamber unit to form a first blowing array. The first blowing unit includes a first upper air pipe and a first lower air pipe arranged opposite each other. A first mesh belt is horizontally installed above the first blowing array. Above the first mesh belt, a second upper air pipe is horizontally arranged in the middle of each drying chamber unit to form a second blowing array. Above the second blowing array, a second mesh belt is horizontally installed. Above the second mesh belt, a third upper air pipe is horizontally arranged in the upper part of each drying chamber unit to form a third blowing array. All the upper air pipes... Both the upper and lower air ducts are connected to the main air duct. All upper air ducts have air inlets only at the bottom, and all lower air ducts have air inlets only at the top. A first fabric channel is formed between the first upper air duct and the first lower air duct, and a second fabric channel is formed between the first mesh belt and the second air blowing array. A third fabric channel is formed between the second mesh belt and the third air blowing array. The first mesh belt and the second mesh belt pass through the second fabric channel and the third fabric channel, respectively. The main body of the drying chamber is provided with a fabric inlet and a fabric outlet. The fabric inlet is aligned vertically with the first fabric channel, and the fabric outlet is aligned vertically with the third fabric channel. The fabric enters through the fabric inlet, passes through the first fabric channel, the second fabric channel, and the third fabric channel in sequence, and exits through the fabric outlet.

[0011] Furthermore, guide rollers for guiding the fabric upward are provided at the turning points where the fabric enters the second fabric channel from the first fabric channel and the third fabric channel from the second fabric channel.

[0012] Furthermore, the first upper air duct and the first lower air duct are mounted on the frame in a height-adjustable manner.

[0013] Furthermore, both the first upper duct and the first lower duct have duct bodies, one end of which is open to form an air inlet. A branch air outlet is provided on the main duct, with each air inlet corresponding to a branch air outlet. The air inlet is located at the branch air outlet corresponding to it, and the vertical height of the air inlet is less than the vertical height of the branch air outlet. A baffle plate is circumferentially fixed to the edge of the air inlet, located within the main duct and fitting against the edge of the branch air outlet. A height adjustment mechanism is installed at each end of the duct body, each height adjustment mechanism including an adjustment rod screwed to the frame. The adjustment rod passes through the frame and connects to the duct body, and a handle is installed on the adjustment rod.

[0014] This invention revolutionizes the fabric feeding mode of existing wax-printed fabric drying rooms. The first fabric channel is located at the bottom of the drying room body, and the fabric is fed in a serpentine pattern inside the drying room body and exits through the third fabric channel located above. This allows the fabric to enter in a relatively dry environment and is not affected by the superposition of the upper fabric channels, which is conducive to fabric drying and improves drying efficiency. In addition, the heat of the first and second fabric channels is fully utilized, saving energy. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 to Figure 4As shown, a wax-printed fabric drying machine includes a drying chamber body 10, which is composed of several drying chamber units 1 connected in series along the production line direction. Within the drying chamber body 10, a first air blowing unit is horizontally arranged in the lower middle part of each drying chamber unit 1, forming a first air blowing array 2. Each first air blowing unit includes a first upper air duct 21 and a first lower air duct 22 arranged opposite to each other. A first mesh belt 3 is horizontally installed above the first air blowing array 2. Above the first mesh belt 3, a second upper air duct 41 is horizontally arranged in the middle of each drying chamber unit 1, forming a second air blowing array 4. Above the second air blowing array 4, a second mesh belt 5 is horizontally installed. Above the second mesh belt 5, a third upper air duct 61 is horizontally arranged in the upper part of each drying chamber unit 1, forming a third air blowing array 6. All the upper and lower air ducts are connected to the main air duct 7. The drying chamber is interconnected, with all upper air ducts having air outlets 201 only at their bottom and all lower air ducts having air outlets 201 only at their top. A first fabric channel 100 is formed between the first upper air duct 21 and the first lower air duct 22; a second fabric channel 200 is formed between the first mesh belt 3 and the second air blowing array 4; and a third fabric channel 300 is formed between the second mesh belt 5 and the third air blowing array 6. The first mesh belt 3 and the second mesh belt 5 pass through the second fabric channel 200 and the third fabric channel 300, respectively. The main body of the drying chamber is provided with a fabric inlet 101 and a fabric outlet 102. The fabric inlet 101 is vertically aligned with the first fabric channel 100, and the fabric outlet 102 is vertically aligned with the third fabric channel 300. Fabric 30 enters through the fabric inlet 101, sequentially passes through the first fabric channel 100, the second fabric channel 200, and the third fabric channel 300, and then exits through the fabric outlet 102. Fabric output; guide rollers 8 are provided at the turning points where the fabric 30 enters the second fabric channel 200 from the first fabric channel 100 and enters the third fabric channel 300 from the second fabric channel 200.

[0021] Furthermore, both the first upper air duct 21 and the first lower air duct 22 have an air duct body 20. One end of the air duct body 20 is open to form an air inlet 202. The main air duct 7 has a branch air outlet 71. The air inlet 202 and the branch air outlet 71 correspond one-to-one. The air inlet 202 is located at the branch air outlet 71 corresponding to the air inlet 202. The vertical height A of the air inlet 201 is less than the vertical height B of the branch air outlet 71. A baffle plate 203 is fixed circumferentially to the edge of the air inlet 202. The baffle plate 203 is located in the main air duct 7 and fits against the edge of the branch air outlet 71. A height adjustment mechanism 9 is installed at each end of the air duct body 20. The height adjustment mechanism 9 includes an adjustment rod 91 screwed to the frame 104. The adjustment rod 91 passes through the frame 104. The adjusting rod 91 is connected to the duct body 20 and has a handle 92 installed on it.

[0022] During operation, fabric 30 enters through inlet 101, undergoes pre-drying in a suspended state in the first fabric channel 100, and then enters the second fabric channel 200. It is then laid on the first mesh belt 3 for the second stage of drying, and the first mesh belt 3 carries the fabric forward. Next, the fabric enters the third fabric channel 300, where it is laid on the second mesh belt 5 for the third stage of drying, and the second mesh belt 5 carries the fabric forward. Finally, it exits through outlet 102. The air outlets 201 of the first upper air duct 21, the first lower air duct 22, the second upper air duct 41, and the third upper air duct 61 all face the fabric surface. This bottom-up fabric path ensures that the fabric enters in a relatively dry environment, without interference from the superimposed upper fabric channels, which is beneficial for fabric drying, improves drying efficiency, and fully utilizes the heat from the first and second fabric channels, saving energy.

[0023] When adjusting the height of the first upper air duct 21, manually rotate the adjusting rod 91. Depending on the direction of rotation, this will either lift the two ends of the duct body 20 of the third upper air duct upwards or pull the two ends of the duct body of the first upper air duct downwards. During this process, the baffle plate 202 remains in contact with the edge of the air distribution port 71 to prevent air leakage. The height of the first lower air duct can be adjusted similarly.

[0024] The installation structure of the first upper air duct and the first lower air duct of this utility model is not limited to that shown in the embodiment. The liftable structure allows the equipment to be adjusted according to the droop of the fabric, so that the air outlet is as close as possible to the fabric surface, thereby improving the drying efficiency. The lifting method of the first upper air duct and the first lower air duct is not limited to the manual adjustment shown in the embodiment, but can also be pneumatic adjustment. The number of drying room units is customized according to actual production needs.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent process transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
