Description

Technical Field

[0001] This utility model relates to the field of narrow strip canvas production technology, specifically a rapid cooling device for narrow strip canvas after impregnation with adhesive. Background Technology

[0002] Narrow striped canvas refers to a thick woven fabric with a narrow width. It is made of cotton or linen as the main raw material and is processed through spinning, warping, and weaving. The finished product is characterized by wear resistance, high strength, and dense texture. The production of narrow striped canvas first uses spinning equipment to make fibers into yarn, and then weaves it into a wide canvas fabric on a loom. Then, according to the needs, the fabric is precisely cut into narrow strips of a few centimeters to more than ten centimeters using a slitting machine. Some products also need to undergo post-processing processes such as impregnation, edge locking, coating, and printing to enhance durability and functionality. After narrow strip canvas is impregnated with adhesive, it needs to be cooled. Forced cooling can quickly solidify and cure the adhesive layer on the surface, thereby locking in its physical and chemical properties and preventing the material from deforming or sticking due to residual heat. The cooling process can also effectively prevent the adhesive from aging or becoming brittle due to prolonged exposure to high temperatures, ensuring that its wear-resistant, anti-slip, and weather-resistant design functions can be stably realized. However, the commonly used cooling method is to use wind power for cooling during the transmission process. In order to effectively cool the PVC-impregnated canvas, a long transmission track is usually required so that the canvas is continuously moved and receives the cold air blown by the fan. This results in a significant increase in the floor space occupied by the entire cooling equipment and a waste of energy. Therefore, a rapid cooling device for narrow strip canvas after PVC impregnation is proposed to address the above problems. Utility Model Content

The control box is installed on one side of the cooling transfer box, and the servo motor is installed on the other side. A mounting frame is welded to the outside of the cooling transfer box, and a cooling fan is bolted to the upper end of the mounting frame. A conveying roller assembly is rotatably installed inside the cooling transfer box, and a liquid injection assembly is sleeved on the outside of the conveying roller assembly.

Detailed Implementation

[0014] 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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A rapid cooling device for narrow strip canvas after impregnation includes a cooling transfer box 1, a control box 2, and a servo motor 3. The control box 2 is installed on one side of the cooling transfer box 1, and the servo motor 3 is installed on the other side. A mounting frame 4 is welded to the outside of the cooling transfer box 1. A cooling fan 5 is bolted to the upper end of the mounting frame 4. A conveying roller assembly 6 is rotatably installed inside the cooling transfer box 1. A liquid injection assembly 7 is sleeved on the outside of the conveying roller assembly 6. The conveying roller assembly 6 includes a roller core 61. A circular hole 62 is opened on the outside of the roller core 61. A roller body 63 is fixedly connected through the roller core 61. A groove 64 is opened on the outside of the roller body 63. A baffle 65 is clamped on the outside of the roller body 63. A fin 66 is fixedly connected to one side of the baffle 65. Two mutually symmetrical bars 67 are fixedly connected to one side of the baffle 65. A locking block 68 is fixedly connected to the side of the baffle 65 near the roller body 63. A rubber band 69 is glued to the side of the bars 67 away from the baffle 65.

[0017] As a further implementation of this solution, the liquid injection assembly 7 includes a rotating ring 71. An annular groove 72 is provided on the inner side of the rotating ring 71, and a liquid infusion pipe 73 is installed on the outer side of the rotating ring 71. A liquid infusion nozzle 74 is installed on one side of the liquid infusion pipe 73. The rotating ring 71 and the roller core 61 form a rotational fit. The annular groove 72 is connected to the circular hole 62. The liquid infusion pipe 73 is U-shaped. Both ends of the liquid infusion pipe 73 are connected to rotating rings 71 that are symmetrically distributed vertically. The rotational fit between the rotating ring 71 and the roller core 61 ensures that the rotating ring 71 remains stationary when the roller core 61 rotates in the rotating ring 71, thus preventing the liquid infusion pipe 73 and the liquid infusion nozzle 74 connected to it from changing position and hindering the fabric transmission. The U-shaped design of the liquid infusion pipe 73 allows it to better simultaneously infuse liquid into the rotating rings 71 connected to both ends, improving the injection efficiency of the coolant. As a further implementation of this solution, multiple conveyor roller assemblies 6 are provided. These multiple conveyor roller assemblies 6 are divided into two groups, and the two groups of conveyor roller assemblies 6 are centrally symmetrically distributed inside the cooling transmission box 1. The main shaft of the servo motor 3 is fixedly connected to any one of the multiple conveyor roller assemblies 6. A cavity is opened on the inner side of the roller core 61. The central axis of the roller core 61 and the central axis of the roller body 63 are on the same straight line. The roller body 63 is shaped like a frustum. The diameter of the roller body 63 at the maximum diameter end is twice the diameter at the minimum diameter end. The shape of the roller body 63 causes the fabric to deflect to a certain extent from the horizontal plane when it is wrapped around the conveyor roller assembly 6. This causes the upper and lower layers of the fabric to be staggered and flipped when the fabric is wrapped back and forth, which greatly increases the exposed area of ​​the front and back sides of the fabric, so that it can be better blown by the cooling fan 5 installed on the upper end of the mounting frame 4. As a further implementation of this scheme, the groove 64 is annular in shape, and multiple grooves 64 are evenly and equidistantly distributed on the surface of the roller body 63. Three locking blocks 68 are provided, with the distance between any two adjacent locking blocks 68 being the same. Part of the locking blocks 68 are disposed in the grooves 64. The baffles 65 are arranged symmetrically in pairs on the outer side of the roller body 63. The fins 66 are arc-shaped. The included angle between the elastic band 69 and the bar 67 is 90°. The upper and lower ends of the elastic band 69 are simultaneously connected to two bars 67. 7. The three locking blocks 68, when locked in the groove 64, can improve the stability of the baffle 65 fixedly connected to it, thus better limiting the position of the fabric by the baffle 65. The arc-shaped design of the fins 66 can better adapt to the shape of the baffle 65, thus providing a more effective heat dissipation effect on one side of the baffle 65. The rubber band 69 allows the fixed bar 67 to exert tension on the upper and lower baffles 65 at the same time, thus locking the baffle 65 onto the roller body 63.

[0018] Working process: When the device is in use, the fabric is wound back and forth on multiple conveyor roller assemblies 6 in the cooling transfer box 1. The shape of the roller body 63 causes the fabric to deflect to a certain extent from the horizontal plane when it is wound on the conveyor roller assembly 6, so that the upper and lower layers of the fabric are staggered when it is wound back and forth. This setting ensures that the fabric has enough length to be cooled by the airflow blown by the cooling fan 5 fixedly installed above the mounting frame 4 during the transfer process. In addition, the fabric will flip when it is wound back and forth, so that both sides of the fabric can be effectively cooled by air. Opening the infusion nozzle 74 allows coolant to be injected into the rotating ring 71 through the infusion nozzle 74 and the infusion tube 73. The coolant in the rotating ring 71 flows into the cavity of the roller core 61 through the annular groove 72 on the inner side of the rotating ring 71 and the circular hole 62 on the roller core 61. The servo motor 3 and the cooling fan 5 are started by the control box 2. When the servo motor 3 starts, the main shaft of the servo motor 3 will drive a conveying roller assembly 6 to rotate. The fabric is wound around the conveying roller assembly 6. As the roller core 61 rotates inside the rotating ring 71, it will also drive the roller body 63 to rotate, thereby conveying the fabric. According to the relative position of the fabric and the roller body 63, the baffle 65 is moved so that the baffle... The side of plate 65 without fins 66 is in contact with the fabric. This arrangement allows the heat from the edge of the fabric to be transferred to the baffle plate 65 and quickly dissipated through the fins 66. The upper and lower baffle plates 65 are respectively subjected to the tension generated by the elastic bands 69 between the bars 67 fixed to them, so that the locking block 68 can be locked into the groove 64, thereby preventing the fabric from sliding on the roller body 63 during conveying. At this time, part of the heat of the fabric wrapped around the conveying roller assembly 6 is transferred to the roller core 61 through the roller body 63 and absorbed by the coolant in the cavity inside the roller core 61. This allows the fabric to dissipate heat through contact with the conveying roller assembly 6 when it is being cooled by the cooling fan 5.

[0019] 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.
