Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a fabric pretreatment device for fabric processing. Background Technology

[0002] Among various fabric materials, nylon is a synthetic fiber material with excellent properties such as high strength and abrasion resistance. Because nylon has better tensile strength and durability than most fiber materials, it can cope with most daily use situations. In order to further enhance the abrasion resistance of nylon fabric, adding a layer of ultrafine glass particle coating to the nylon fabric can significantly enhance the hardness and abrasion resistance of the nylon fabric. This coating can protect the nylon fabric from damage caused by friction and scratches, and extend the service life of the nylon fabric. Before applying the ultrafine glass particle coating to the nylon fabric, pretreatment processes such as washing and drying are required.

[0003] For example, Chinese Patent Publication No. CN208821796U discloses a fabric pretreatment device for garment production, comprising a fabric cleaning machine and garment fabric. First conveying rollers are installed on both the left and right sides of the upper surface of the fabric cleaning machine. A drying chamber is fixedly connected to the upper surface of the fabric cleaning machine, near the left side of the first conveying roller. A hot air fan is installed on the upper surface of the fabric cleaning machine, near the left side of the drying chamber. This fabric pretreatment device effectively absorbs and dries moisture from already damp garment fabric, eliminating the problem of production being carried out with the fabric in a wet state.

[0004] The above application still has shortcomings. In the above application, hot air is blown out of the hot air outlet pipe onto the fabric being transported and dried. However, the contact time between the hot air and the fabric is short, and the fabric is difficult to dry sufficiently. At the same time, there is a lack of pretreatment before drying the wet fabric, resulting in poor drying effect.

[0005] Therefore, it is necessary to provide a fabric pretreatment device before fabric processing to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a fabric pretreatment device before fabric processing, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: a fabric pretreatment device for fabric processing, comprising a base plate, a serpentine tube fixed to the top side of the base plate, an inlet and an outlet at both ends of the serpentine tube, a ventilation cavity formed in the side wall of the serpentine tube, an air blowing hole communicating with the ventilation cavity formed on the inner side wall of the serpentine tube, an air inlet pipe communicating with the ventilation cavity fixed to the outer side wall of the serpentine tube, a support platform fixed to the top side of the base plate, and a pre-compression component located on the inlet side of the support platform.

[0008] As a further embodiment of this utility model, two guide rollers are provided at the corners of the serpentine tube, and both ends of the guide rollers are rotatably connected to the side wall of the serpentine tube.

[0009] As a further embodiment of this utility model, the pre-compression assembly includes a support plate fixed to the side of the top of the support platform. Two support plates are provided and the two support plates are symmetrically distributed. A pressure roller is provided between the two support plates. One end of the pressure roller is fixed with an end shaft arranged coaxially with the pressure roller. The end shaft is rotatably connected to the support plate. A motor is fixed on the side of the support plate, and the output end of the motor is fixed to the end shaft.

[0010] As a further embodiment of this utility model, the pressure roller has an inner cavity, and a suction hole communicating with the inner cavity is provided on the cylindrical side of the inner cavity. A connector sleeve is fixed on the end of the pressure roller away from the end shaft, and a suction tube is rotatably connected to the end port of the connector sleeve away from the pressure roller through a bearing.

[0011] As a further embodiment of this utility model, the suction holes are provided in multiple locations and are equidistantly distributed.

[0012] As a further embodiment of this utility model, a support plate is fixed on the top side of the base plate, and the serpentine tube is fixed on the top of the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The fabric moves in through the inlet and out through the outlet, and is conveyed in a serpentine path inside the serpentine tube. During this process, hot air is delivered to the ventilation chamber through the air inlet pipe and is evenly blown out through multiple equally spaced air holes onto both sides of the fabric moving inside the serpentine tube. This allows for simultaneous and uniform drying of both sides of the fabric, improving the drying efficiency. At the same time, the serpentine path of the fabric greatly increases the contact between the fabric and the hot air blown out of the air holes, effectively improving the drying effect.

[0015] 2. Before the fabric enters the hot air drying tube, the pre-compression component squeezes out the moisture from the fabric, thereby greatly reducing the water content in the fabric. This allows the fabric to be pre-treated before entering the hot air drying tube, effectively reducing the load on the hot air drying inside the tube and improving the fullness of fabric drying.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-6This utility model provides a fabric pretreatment device before fabric processing, including a base plate 9, a serpentine tube 3 fixed on the top side of the base plate 9, an inlet 4 and an outlet 5 at both ends of the serpentine tube 3, a ventilation cavity 11 opened in the side wall of the serpentine tube 3, an air blowing hole 6 communicating with the ventilation cavity 11 opened on the inner side wall of the serpentine tube 3, an air inlet pipe 2 communicating with the ventilation cavity 11 fixed on the outer side wall of the serpentine tube 3, a support platform 8 fixed on the top side of the base plate 9, and a pre-compression component 1 located on the top of the support platform 8 on the side of the inlet 4; in use, the fabric is wound and conveyed by a winding roller, the fabric moves into the inlet 4 and out through the outlet 5, and the fabric moves and is conveyed in a serpentine path inside the serpentine tube 3. A hot air fan is connected to the air inlet pipe 2. During the process of the fabric moving and being conveyed in a serpentine path inside the serpentine tube 3... Hot air is delivered to the air inlet duct 2 by a hot air blower, and then to the ventilation chamber 11 through the air inlet duct 2. The hot air is then evenly blown out through multiple equally spaced air blowers 6 onto both sides of the fabric moving inside the serpentine tube 3, thereby simultaneously and evenly drying both sides of the fabric and improving the drying efficiency. At the same time, the serpentine path of the fabric greatly improves the contact between the fabric and the hot air blown out of the air blowers 6, effectively improving the drying effect of the fabric. Before the fabric enters the hot air drying inside the serpentine tube 3, the fabric moves through the pre-compression component 1. During this process, the pre-compression component 1 squeezes out the moisture in the fabric, thereby greatly reducing the water content in the fabric. This achieves pretreatment of the fabric before it enters the hot air drying inside the serpentine tube 3, effectively reducing the load of the hot air drying inside the serpentine tube 3 and ensuring that the fabric is fully dried.

[0027] Further as Figure 1 , Figure 5 and Figure 6 As shown, it is worth noting that the pre-compression assembly 1 includes a support plate 107 fixed to the side of the top of the support platform 8. Two support plates 107 are provided and symmetrically distributed. A pressure roller 101 is arranged between the two support plates 107. One end of the pressure roller 101 is fixed with an end shaft 106 arranged coaxially with the pressure roller 101. The end shaft 106 is rotatably connected to the support plate 107. A motor 108 is fixed to the side of the support plate 107, and the output end of the motor 108 is fixed to the end shaft 106. Before the fabric enters the hot air drying chamber of the serpentine tube 3, the fabric adheres to the top side of the support platform 8 and passes through the bottom of the pressure roller 101. The pressure roller 101 and the fabric are pressed together. During this process, the pressure roller 101 is rotated by the motor 108, thereby squeezing out the moisture from the fabric through the pressure roller 101. This greatly reduces the water content in the fabric, achieving pretreatment of the fabric before it enters the hot air drying chamber of the serpentine tube 3. This effectively reduces the load on the hot air drying inside the serpentine tube 3 and ensures that the fabric is fully dried.

[0028] Further as Figure 6As shown, it is worth noting that the pressure roller 101 has an inner cavity 104 inside. The cylindrical side of the inner cavity 104 has suction holes 105 that communicate with the inner cavity 104. There are multiple suction holes 105, and the multiple suction holes 105 are evenly distributed. A connector sleeve 102 is fixed on the end of the pressure roller 101 away from the end shaft 106. The end port of the connector sleeve 102 away from the pressure roller 101 is rotatably connected to a suction pipe 103 through a bearing. In specific operation, the suction pipe 103 is connected to a suction pump. The suction pump creates a negative pressure suction between the suction pipe 103 and the inner cavity 104, thereby sucking out the liquid squeezed out of the fabric by the pressure roller 101 through the multiple suction holes 105, and promptly removing the squeezed liquid to improve the drying pretreatment effect of the fabric.

[0029] This solution has the following working process: Before the fabric enters the serpentine tube 3 for hot air drying, the fabric adheres to the top side of the support platform 8 and passes through the bottom of the pressure roller 101. The pressure roller 101 and the fabric are in contact. During this process, the motor 108 drives the pressure roller 101 to rotate, thereby squeezing out the moisture in the fabric and greatly reducing the water content in the fabric. The squeezed fabric moves into the inlet 4 and out through the outlet 5. The fabric moves and is conveyed in a serpentine path inside the serpentine tube 3. During the process of the fabric moving and being conveyed in a serpentine path inside the serpentine tube 3, the hot air is delivered to the ventilation chamber 11 through the air inlet pipe 2 and is evenly blown out through multiple equally spaced air holes 6 onto both sides of the fabric moving inside the serpentine tube 3, thereby simultaneously and evenly drying both sides of the fabric.

[0030] Further as Figure 1 As shown, it is worth noting that a support plate 10 is fixed on the top side of the base plate 9, and the serpentine tube 3 is fixed on the top of the support plate 10. In actual operation, the support plate 10 ensures that the inlet 4 has a certain height.

[0031] Further as Figure 3 and Figure 4 As shown, it is worth noting that two guide rollers 7 are provided at the corners of the serpentine tube 3. Both ends of the guide rollers 7 are rotatably connected to the side wall of the serpentine tube 3. In actual operation, the guide rollers 7 are used to guide the fabric to move and transport, thereby improving the stability of the fabric movement and transport inside the serpentine tube 3.

[0032] In summary: The fabric moves in through inlet 4 and out through outlet 5, moving along a serpentine path inside the serpentine tube 3. A hot air blower is connected to the air inlet 2. During this serpentine movement, the hot air blower delivers hot air into the air inlet 2 and then into the ventilation chamber 11. The hot air is then evenly blown out through multiple equidistant air holes 6 onto both sides of the fabric moving within the serpentine tube 3, thus simultaneously and evenly drying both sides of the fabric and improving drying efficiency. The serpentine path also significantly increases the contact between the fabric and the hot air blown out through the air holes 6, effectively improving the drying effect. Before entering the hot air drying chamber of the serpentine tube 3, the fabric passes through the pre-compression component 1. During this process, the pre-compression component 1 squeezes out moisture from the fabric, greatly reducing its water content. This pre-treatment of the fabric before it enters the hot air drying chamber of the serpentine tube 3 effectively reduces the load on the hot air drying process inside the serpentine tube 3, ensuring thorough drying of the fabric.

[0033] The motor 108 can be purchased from the market. The motor 108 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
