Description

Technical Field

[0001] This utility model relates to the field of textile material processing technology, and in particular to a flame retardant impregnation device for coated Oxford cloth. Background Technology

[0002] By uniformly impregnating the surface of Oxford cloth with flame retardant, a strong flame retardant coating is formed, thereby improving the flame retardant performance of Oxford cloth. It is widely used in outdoor equipment (such as tents, backpacks, etc.) and industrial protective equipment (such as fireproof clothing, high-temperature work clothes, etc.). Using flame retardant treated Oxford cloth can effectively improve the safety and durability of products.

[0003] In existing coated Oxford cloth production processes, flame retardant coating is typically carried out manually or with simple mechanical devices. These methods often suffer from uneven coating, low efficiency, and complex operation, while larger devices are quite expensive. Therefore, developing a device that can simply, stably, and uniformly coat flame retardants is of great significance for improving the production quality and efficiency of coated Oxford cloth. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that rely on manual or simple mechanical methods, which often suffer from uneven coating, low efficiency, and complex operation, while larger devices are also expensive. Therefore, this invention proposes a flame retardant impregnation device for coating Oxford cloth.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flame retardant impregnation device for coated Oxford cloth, comprising a housing;

[0007] An impregnation tank and a main coating roller are used to apply flame retardant to the surface of Oxford cloth. The impregnation tank is fixedly installed on the bottom inner wall of the housing, and the main coating roller is rotatably installed inside the impregnation tank.

[0008] A guide assembly for guiding Oxford cloth is disposed inside the housing. The guide assembly includes a first guide roller and two second guide rollers, which are rotatably disposed on both sides inside the housing. The first guide roller is disposed inside the housing and is located above the main coating roller.

[0009] In one possible design, the guide assembly further includes a rotating rod rotatably mounted on one side of the housing. A through-hole is provided on one side of the housing, through which the shaft of the first guide roller extends to the outside of the housing. A sliding plate is slidably mounted on one side of the housing and fitted onto the outer wall of the first guide roller. A sliding shell is fixedly mounted on one side of the sliding plate, with an inner cavity inside the sliding shell. A sliding rod is slidably mounted inside the inner cavity. A spiral groove and an annular groove are provided on the outer wall of the rotating rod, with the annular groove located below the spiral groove. The bottom end of the spiral groove communicates with the outer side of the top inner wall of the annular groove. One end of the sliding rod engages with both the spiral groove and the annular groove.

[0010] In one possible design, a second compression spring is provided inside the inner cavity, and the two ends of the second compression spring are respectively fixedly provided on one end of the slide rod and one side of the inner wall of the inner cavity. A limit rod is fixedly provided on one side of the outer shell, and the slide plate is slidably sleeved on the outer wall of the limit rod. A first compression spring is sleeved on the outer wall of the limit rod, and the two ends of the first compression spring are respectively fixedly provided on one side of the outer shell and the bottom of the slide plate.

[0011] In one possible design, a pull plate is fixedly provided on the outer wall of the slide rod, and one end of the pull plate slides through to the outside of the slide shell.

[0012] In one possible design, the guide assembly further includes two meshing bevel gears, one end of the main paint roller rotates through to the outside of the housing, the two bevel gears are respectively fixedly sleeved on the outer wall of the rotating rod and the outer wall of the main paint roller, and a servo motor is provided on one side of the housing, the output shaft of the servo motor is fixedly provided at one end of the main paint roller.

[0013] In one possible design, a secondary paint roller is rotatably mounted inside the housing, with one end of the secondary paint roller rotatably extending to the outside of the housing. Synchronous pulleys are fixedly mounted on the outer walls of both the secondary paint roller and the main paint roller, and the outer walls of the two synchronous pulleys are driven by the same synchronous belt.

[0014] In one possible design, at least one scraper is provided inside the housing.

[0015] In this application, during actual use, the Oxford cloth passes between the guide roller and the coating roller. Then, the servo motor is activated to drive the main coating roller. When the main coating roller rotates, it drives the rotating rod to rotate via the bevel gear. At this time, the slide rod, influenced by the spiral groove, moves the sliding housing downwards. The sliding housing, through the sliding plate, moves the first guide roller downwards. The first guide roller then moves the fabric downwards, bringing it into contact with the coating roller below. Simultaneously, the slide rod moves to the side of the annular groove. The slide rod, under the force of the second compression spring, causes one end to enter the interior of the annular groove, fixing the first guide roller in place. Figure 3The diagram shows that when it is necessary to release the fixation, simply pull the pull plate. The pull plate will move the slide rod to disengage it from the inside of the annular groove. Then, the first guide roller can be reset by the first compression spring.

[0016] In this utility model, the flame retardant impregnation device for coated Oxford cloth, through the guide component, can achieve uniform coating of flame retardant and stable transport of Oxford cloth, and can make the Oxford cloth stably contact the coating roller during the initial placement, thereby improving coating quality and efficiency.

[0017] In this invention, the flame retardant impregnation device for coated Oxford cloth can remove excess flame retardant by scraping off the scraper, ensuring the thickness and uniformity of the coating and improving the coating quality.

[0018] In this invention, after the fabric is passed through the coating roller and the guide roller, the coating roller is driven to rotate, which in turn drives the guide roller to move downward until the fabric comes into contact with it. When the coating roller rotates, the flame retardant impregnated on the surface of the fabric is coated onto the fabric surface. The operation is simple and can ensure the contact between the fabric and the coating roller. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1-2 An impregnation device includes: a housing 1, an impregnation tank 2, a secondary coating roller 3, a main coating roller 4, and guide components, etc.

[0029] The impregnation tank 2 is fixedly installed on the bottom inner wall of the outer casing 1 and is used to hold the flame retardant. The main coating roller 4 is rotatably installed inside the impregnation tank 2, and its surface is in contact with the flame retardant, thereby applying the flame retardant to the surface of the Oxford cloth as it rotates.

[0030] The guiding assembly guides the Oxford cloth through the device, ensuring its stability and accuracy during the coating process. The guiding assembly includes a primary guide roller 5, two secondary guide rollers 6, a rotating rod 13, a sliding plate 15, a sliding housing 16, a sliding rod 12, a spiral groove 11, an annular groove 10, a limiting rod 14, a primary compression spring 18, a secondary compression spring 20, and a pull plate 17. The two secondary guide rollers 6 are rotatably mounted on opposite sides inside the outer casing 1, while the primary guide roller 5 is positioned above the main coating roller 4.

[0031] Reference Figure 4-5 A rotating rod 13 is rotatably mounted on one side of the outer casing 1, and a first guide roller 5 extends to the outside through a through hole. A sliding plate 15 is slidably mounted on one side of the outer casing 1 and sleeved on the outer wall of the first guide roller 5 to control its position. A sliding shell 16 is fixedly mounted on one side of the sliding plate 15, and has an inner cavity 19 for mounting a sliding rod 12 and a second compression spring 20. One end of the sliding rod 12 engages with the spiral groove 11 and annular groove 10 on the outer wall of the rotating rod 13. A first compression spring 18 is sleeved on the outer wall of the limiting rod 14 and fixed to both the outer casing 1 and the sliding plate 15 to provide the restoring force for the sliding plate 15. A pull plate 17 is fixedly mounted on the outer wall of the sliding rod 12 and slides through to the outside of the sliding shell 16 for easy manual operation of the sliding rod 12.

[0032] The guide assembly also includes two meshing bevel gears 7, one of which is fixedly sleeved on the outer wall of the rotating rod 13, and the other is fixedly sleeved on the outer wall of the main paint roller 4. The main paint roller 4 is driven to rotate by a servo motor 8, which in turn drives the rotating rod 13 to rotate.

[0033] Specifically, the Oxford cloth passes between the guide roller and the coating roller. Then, the servo motor 8 is activated to drive the main coating roller 4. When the main coating roller 4 rotates, it drives the rotating rod 13 to rotate via the bevel gear 7. At this time, the slide rod 12, influenced by the spiral groove 11, causes the sliding housing 16 to move downwards. The sliding housing 16, through the sliding plate 15, drives the first guide roller 5 downwards. The first guide roller 5 then moves the fabric downwards, bringing it into contact with the coating roller below. Simultaneously, the slide rod 12 moves to the side of the annular groove 10. The slide rod 12, under the force of the second compression spring 20, causes one end to enter the interior of the annular groove 10, fixing the first guide roller 5 in place. Figure 3 The diagram shows that when it is necessary to release the fixation, simply pull the pull plate 17. The pull plate 17 drives the slide rod 12 to move so that it is disengaged from the inside of the annular groove 10. Then the first guide roller 5 can be reset by the first compression spring 18.

[0034] This application can be used in the field of textile material processing, or in other fields applicable to this application.

[0035] Example 2

[0036] refer to Figure 2 , Figure 4 An improvement upon Example 1 is provided: a flame retardant impregnation device for coated Oxford cloth, applied in the field of textile material processing. The auxiliary coating roller 3 is rotatably disposed inside the outer casing 1, with one end extending to the outside of the casing 1 and connected to the main coating roller 4 via a synchronous pulley and synchronous belt 9. Thus, when the main coating roller 4 rotates, it can drive the auxiliary coating roller 3 to rotate synchronously, further improving the uniformity and efficiency of coating.

[0037] To further improve coating quality, at least one scraper 22 is also provided inside the housing 1. The scraper 22 cooperates with the adjacent coating roller to scrape off excess flame retardant, ensuring the thickness and uniformity of the coating.

[0038] Reference Figure 6 A protective shell is provided on one side of the outer casing 1, and the normal operation of the device is ensured by placing equipment such as the servo motor 8 inside it.
