Description

Technical Field

[0001] The utility model relates to a multi-roller padding machine, belonging to the technical field of textile equipment. Background Art

[0002] In the production and dyeing and finishing processes of textile fabrics, there are many situations where the fabrics need to be impregnated with reagents. For example, the mercerizing process requires the mercerizing agent to be fully impregnated and penetrated into the fabric, and the fluorescent whitening treatment requires the fluorescent whitening agent to be impregnated and penetrated into the fabric. In order to ensure that the functional reagents can fully penetrate into the fabric fibers, such processes generally require the fabric to be impregnated and rolled in the reagent solution multiple times. However, the existing fabric impregnation production equipment is difficult to ensure that the reagents penetrate fully and evenly during the repeated impregnation and rolling operations on the fabric, and it is difficult to ensure the process effect. At the same time, it is easy to cause additional damage to the fabric, such as curling, creases, breakage, etc., which reduces the quality of the fabric. The impregnation production efficiency is low, the production cost is high, and it is not suitable for mass production. Therefore, there is an urgent need for a fabric impregnation rolling mill with good fabric impregnation effect, high quality, high production efficiency and low cost. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a multi-roller impregnation machine with good fabric impregnation effect, high quality, high production efficiency and low cost.

[0004] The purpose of this utility model is achieved in this way:

[0005] A multi-roller impregnation machine comprises a box body, a wire separation roller arranged at the left end of the box body, an immersion tank arranged at the bottom of the box body and filled with impregnation liquid, a plurality of steel rollers arranged horizontally in the immersion tank with the lower part immersed in the impregnation liquid, and a plurality of rubber rollers arranged horizontally above the steel rollers; each rubber roller is located between two adjacent steel rollers to form a herringbone structure, and a synchronous deflection action is achieved by a lifting mechanism; the steel rollers are driven by a gear chain and driven by a main motor to achieve synchronous and unidirectional rotation; the wire separation roller is rotated by an auxiliary motor through a worm gear, guiding the fabric into the box body, and the fabric circulates around a plurality of steel rollers and rubber rollers in turn, and then exits the box body from the bottom of the last steel roller.

[0006] Furthermore, the lifting mechanism includes a deflection shaft rotatably set on the box body, a support arm and a deflection arm respectively fixed on the two ends of the deflection shaft; the rubber roller is rotatably set on the support arm; the deflection arm is pushed by the cylinder to deflect around the deflection shaft, driving the deflection shaft and the support arm to deflect, and then driving the rubber roller to deflect.

[0007] Furthermore, the support arms corresponding to each rubber roller are hinged via a connecting rod, ensuring that each rubber roller performs synchronous deflection action.

[0008] Furthermore, both ends of the connecting rod are connected to the hinged portion of the support arm through external threaded joint bearings.

[0009] Furthermore, a tensioning sprocket is provided between two adjacent steel rollers to adjust the tightness of the transmission chain and ensure accurate and effective power transmission.

[0010] Furthermore, the wire separation roller is symmetrically provided with external threads extending toward both ends, so as to extend both side edges of the fabric outwards to prevent curling.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model adopts a method of horizontally arranging multiple synchronously rotating steel rollers in the same impregnation tank, and arranging rubber rollers with adjustable rolling pressure between the steel rollers, so that the fabric maintains constant tension and completes multiple impregnation and rolling operations when passing around each steel roller and rubber roller, greatly improving the impregnation permeability and uniformity of the fabric, improving the impregnation effect, improving the impregnation production efficiency, and reducing production costs. At the same time, symmetrical external rotating threads are arranged on the wire separation rollers to prevent the fabric from curling and preventing the fabric from being damaged during the impregnation production process, thereby improving the quality and grade of the fabric.

DETAILED DESCRIPTION

[0018] See also Figures 1 to 3 The utility model relates to a multi-roll impregnation mill, comprising a box body 1, a wire separation roller 5 arranged at the left end of the box body 1, an immersion tank 2 arranged at the bottom of the box body 1 and filled with an impregnation liquid, a plurality of steel rollers 3 arranged horizontally in the immersion tank 2 with the lower parts immersed in the impregnation liquid, and a plurality of rubber rollers 4 arranged horizontally above the steel rollers 3; the number of the rubber rollers 4 is one less than the number of the steel rollers 3, each rubber roller 4 is located between two adjacent steel rollers 3 to form a herringbone structure, and a synchronous deflection action is achieved by a lifting mechanism; in this embodiment, there are three steel rollers 3 and two rubber rollers 4;

[0019] The steel rollers 3 are driven by a gear chain and driven by a main motor 6 to achieve synchronous and unidirectional rotation. A tensioning sprocket 14 is provided between two adjacent steel rollers 3 to adjust the tightness of the transmission chain, ensuring accurate and effective power transmission, ensuring accurate synchronization of the speed of each steel roller 3, and preventing uneven tension of the fabric.

[0020] The lifting mechanism includes a deflection shaft 8 rotatably mounted on the housing 1, and support arms 9 and a deflection arm 10 fixedly mounted at both ends of the deflection shaft 8. The rubber roller 4 is rotatably mounted on the support arm 9. The deflection arm 10 is driven by a cylinder 11 to deflect about the deflection shaft 8, thereby driving the deflection shaft 8 and the support arm 9 to deflect, and further driving the rubber roller 4 to deflect. The cylinder 11 controls the rubber roller 4 to separate from or contact the steel roller 3, and adjusts the contact pressure between the rubber roller 4 and the steel roller 3, that is, the pressing force applied to the fabric.

[0021] The support arms 9 corresponding to each rubber roller 4 are hinged by a connecting rod 12. The hinged parts of the two ends of the connecting rod 12 and the support arms 9 are connected by external threaded joint bearings 13, which eliminate the activity error of the hinged parts and ensure the synchronization of the movements of each support arm 9. In this way, only one cylinder 11 is needed to control the synchronous deflection movement of all rubber rollers 4. At the same time, the consistency of the contact pressure of each rubber roller 4 on the steel roller 3 is ensured, so that the rolling pressure of the fabric between each group of rubber rollers 4 and steel rollers 3 remains stable, ensuring the stability of the tension of the fabric during multiple dipping and rolling processes;

[0022] The wire separation roller 5 is rotated by the auxiliary motor 7 through the worm gear transmission, guiding the fabric into the box body 1. The fabric circulates around several steel rollers 3 and rubber rollers 4 in sequence and exits the box body 1 from the bottom of the last steel roller 3; the wire separation roller 5 is symmetrically provided with external threads 15 that expand toward both ends, which expand the two side edges of the fabric outward to prevent curling and affect the quality of the fabric.

[0023] During production, the fabric is guided by the wire separation roller 5 into the impregnation tank 2 of the box body 1, and passes through the first steel roller 3 to complete the first impregnation, passes through the first steel roller 3 and the first rubber roller 4 for the first rolling, passes through the first rubber roller 4 and then passes through the first rubber roller 4 and the second steel roller 3 to complete the second impregnation, and then passes through the second steel roller 3 after three impregnations and four rollings. Finally, it passes through the bottom of the third steel roller 3 and exits the box body 1, completing multiple impregnation and rolling production. The utility model has a simple structure, good fabric impregnation effect, high quality, high production efficiency, and low cost.

[0024] In addition: It should be noted that the above specific implementation is only an optimization scheme of this patent. Any changes or improvements made by technicians in this field based on the above concept are within the scope of protection of this patent.
