A steaming and washing box for printing and dyeing

Abstract

The invention relates to the technical field of textile steam-cleaning boxes, and in particular to a steam-cleaning box for printing and dyeing, a steam-cleaning box body, and a cloth inlet and a cloth outlet are respectively arranged on the left and right sides of the steam-cleaning box body. The invention provides a turbulence generator. When in use, cloth enters the steam-cleaning box body through the cloth inlet, and is successively wound up and down by a first guide roller, a second guide roller, and a third guide roller to be transported to the cloth outlet. During the cleaning process, the cloth is fixed between the limit plates and contacts with the surface of an annular cylinder. As the third guide roller rotates, an adjustment mechanism causes a blade to rotate back and forth around a first rotating shaft and a second rotating shaft between the annular cylinder and an adjustment support, and the inclination angle of the blade is continuously adjusted. At the same time, the annular cylinder drives the blade to rotate along the moving direction of the cloth, thereby generating kinetic energy for the cleaning liquid, and pushing the cleaning liquid in the steam-cleaning box body to move back and forth along the length direction of the third guide roller, causing the cleaning liquid to form turbulence, increasing the friction and impact force between the cleaning liquid and the cloth surface, and thus significantly improving the cleaning effect of the cloth.

DETAILED DESCRIPTION

Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention.

To be more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0035] When the existing steam-cleaning box is in use, a proper amount of cleaning liquid is usually injected into the box body, and the cloth is input from the cloth inlet through the cloth guide roller, and is transported through the roller shaft in the box body, so that the cloth contacts the high-temperature cleaning liquid, and is finally output from the cloth outlet to the next processing unit. When the cloth moves in the steam-cleaning box, the cleaning liquid remains stationary, making it difficult to completely separate the cloth from the oil, lint and other dirt on the cloth, thereby affecting the cleaning effect. In order to solve the above technical problems, this case proposes the following technical solutions:

[0036] Reference Figures 1 to 13 As shown, a steam-washing box for printing and dyeing, the structure of which includes: a steam-washing box body 1, a cloth inlet and a cloth outlet are respectively arranged on the left and right sides of the steam-washing box body 1, a cloth guide group assembly is arranged inside the steam-washing box body 1, and the cloth guide group assembly includes a first guide roller 2 respectively arranged at the cloth inlet and the cloth outlet and a second guide roller 3 arranged at the top of the steam-washing box body 1, and also includes a third guide roller 4 arranged between the first guide rollers 2 at the cloth inlet and the cloth outlet, cloth 5 is wound on the first guide roller 2, the second guide roller 3, and the third guide roller 4, and the third guide roller 4 includes a plurality of turbulence generators 41 arranged in parallel, and limit plates 42 arranged on both sides of the cloth 5, which are located between two adjacent turbulence generators 41 and the turbulence generators. The turbulence generator 41 comprises an annular cylinder 411, an adjusting support 412 arranged in the middle of the annular cylinder 411, a plurality of blades 413 are distributed in an annular shape between the inner side of the annular cylinder 411 and the adjusting support 412, a first rotating shaft 414 and a second rotating shaft 415 are respectively provided at the upper and lower ends of the blades 413, a plurality of mounting holes 416 correspondingly provided on the inner wall of the annular cylinder 411 and rotatably matched with the first rotating shaft 414 are provided, and an adjusting mechanism for synchronously adjusting the inclination angle of the blades 413 in the annular cylinder 411 is provided in the adjusting support 412; a transmission mechanism 6 for driving the third guide roller 4 to rotate along the moving direction of the cloth 5 is also provided outside the steam-washing box 1.

[0037] Therefore, in use, the cloth enters the steaming and washing box 1 through the cloth inlet, and is wound up and down by the first guide roller 2, the second guide roller 3, and the third guide roller 4 in turn and transported to the cloth outlet. During the cleaning process, the cloth is fixed between the limit plates 42 and contacts the surface of the annular cylinder 411, and the transmission mechanism 6 drives the third guide roller 4 to rotate along the moving direction of the cloth 5. As the third guide roller 4 rotates, the adjustment mechanism causes the blade 413 to rotate back and forth around the first rotating shaft 414 and the second rotating shaft 415 between the annular cylinder 411 and the adjustment support 412, and continuously adjusts the inclination angle of the blade 413. At the same time, the annular cylinder 411 drives the blade 413 to rotate along the moving direction of the cloth, thereby generating kinetic energy for the cleaning liquid, pushing the cleaning liquid in the steaming and washing box 1 to move back and forth along the length direction of the third guide roller 4, causing the cleaning liquid to form turbulence, increasing the friction and impact force between the cleaning liquid and the cloth surface, thereby significantly improving the cleaning effect of the cloth.

[0038] The diameter of each annular cylinder 411 is the same, and the width is 20-50 cm, and the distance between two adjacent annular cylinders 411 is kept consistent, so that the cloth is evenly stressed when being conveyed on the third guide roller 4, preventing the cloth from deforming and ensuring the stability of the cloth conveying.

[0039] In addition, the limit plates 42 on both sides of the third guide roller 4 are fixedly installed inside the steam-washing box 1 through bearings, and one end of each of the limit plates 42 is mechanically connected to the transmission mechanism 6. Therefore, the limit plates 42 are driven to rotate through the transmission mechanism 6. At the same time, the limit plates 42, the connecting parts 43 and the turbulence generator 41 are fixedly connected, thereby prompting the transmission mechanism 6 to drive the third guide roller 4 to rotate in the steam-washing box 1.

[0040] Specifically, the outer side of the adjustment support 412 is provided with a plurality of positioning holes 417 corresponding to the second rotating shaft 415, and the outer side of the second rotating shaft 415 is surrounded by a driving slide groove 418. The adjustment mechanism includes a slider 71 slidably connected to the inner side of the adjustment support 412 and arranged corresponding to the positioning hole 417. The adjustment support 412 is provided with a T-slot 419 for the slider 71 to slide. The slider 71 is provided with a connecting groove 72 that cooperates with the second rotating shaft 415. The inner wall of the connecting groove 72 is provided with a protrusion 73 that cooperates with the driving slide groove 418. The protrusion 73 slides along the driving slide groove 418 for a quarter of a circle to cause the second rotating shaft 415 to rotate ninety degrees. A return spring 74 is also provided between the connecting groove 72 and the second rotating shaft 415. The adjustment support 412 is also provided with a driving mechanism that pushes the slider 71 to reciprocate in the T-slot 419.

[0041] It should be noted that the driving slide 418 is composed of four sections of slides that slide in a circular upward and downward manner. The upper and lower ends of each section of the slide are provided with sliding inclined surfaces that enable the protrusion 73 to slide into the next section of the slide. Therefore, each time the protrusion 73 slides along the slide to the top, it slides along the inclined surface of the slide to the bottom of the next section of the slide when it slides down, thereby driving the second rotating shaft 415 to rotate 90 degrees.

[0042] Moreover, the blades 413 are initially at an angle of 30°-60° to the diameter of the annular tube 411, thereby ensuring that after each rotation, the blades 413 and the annular tube 411 are at a certain angle. As the annular tube 411 drives the blades 413 to rotate, kinetic energy is generated on the water flow, driving the water flow to move, thereby generating turbulence.

[0043] Therefore, as the annular cylinder 411 rotates in the steam-washing box 1, the driving mechanism drives the slider 71 to reciprocate in the T-slot 419 of the adjustment support 412. When the slider 71 slides toward the blade 413, the return spring 74 is compressed, and the protrusion 73 moves up along the driving slide groove 418. After moving to the top of the driving slide groove 418, it moves down along the slide groove. At the same time, the return spring 74 is expanded downward, thereby driving the blade 413 to rotate through the second rotating shaft 415, thereby continuously adjusting the inclination angle of the blade 413, causing the cleaning liquid in the steam-washing box 1 to form turbulence, increasing the friction and impact force between the cleaning liquid and the surface of the cloth, thereby significantly improving the cleaning effect of the cloth.

[0044] Further, the front and rear ends of the slider 71 are respectively provided with guide slide columns 75, and the driving mechanism includes a driving roller 81 coaxially arranged in the adjustment support 412, and the two ends of the driving roller 81 are respectively fixedly connected to the front and rear ends of the steam-washing box 1, and the adjustment support 412 is sleeved on the outside of the driving roller 81. The driving roller 81 is provided with a limiting step groove 82 for the slider 71 to rotate around the axis, and the two sides of the limiting step groove 82 are respectively provided with guide rails 83 slidably connected to the guide slide column 75. When the guide slide column 75 slides along the guide rail 83, it causes the slider 71 to reciprocate in the T-slot 419;

[0045] It should be noted that the guide rail 83 is composed of a number of guide rail sections equal to the number of blades 413, and each section of the guide rail 83 is connected to each other in an arc shape. When the guide slide column 75 slides to the bottom end along the guide rail 83, it drives the slider 71 to move downward in the T-slot 419. When it moves to the top end of the guide rail 83, it pushes the slider 71 to move upward in the T-slot 419, thereby realizing the reciprocating motion of the slider 71 in the T-slot 419.

[0046] Therefore, since the driving roller 81 remains fixed in the steam-washing box 1, as the third guide roller 4 moves in the steam-washing box 1, the annular cylinder 411, the blades 413, the adjustment support 412 and the driving roller 81 move relative to each other, causing the guide slide column 75 to slide along the guide rail 83, thereby driving the slider 71 to reciprocate in the T-slot 419, so that the blades 413 continuously adjust the inclination angle, thereby causing the cleaning liquid to form turbulence.

[0047] The limiting plate 42 is provided with a through hole for the driving roller 81 to pass through, thereby ensuring that the third guide roller 4 rotates normally in the steaming and washing box 1.

[0048] One end of the driving roller 81 is fixed in the steam-washing box 1, and the other end is connected to the outside of the steam-washing box 1, and an air duct for gas circulation is provided in the driving roller 81. A plurality of aeration heads 84 are distributed on the surface of the driving roller 81, and the aeration heads 84 are connected to the air duct. One end of the driving roller 81 that passes through the outside of the steam-washing box 1 is connected to a high-pressure air pipe 9. Therefore, during the cleaning process, the high-pressure gas is transported into the air duct of the driving roller 81 through the high-pressure air pipe 9, causing the high-pressure gas to be ejected outward through the aeration head 84, which not only enhances the contact and friction between the cleaning liquid and the cloth, but also improves the dirt removal efficiency, thereby significantly improving the cleaning effect of the cloth.

[0049] Specifically, the transmission mechanism 6 includes a transmission gear 61 fixed on the limit plate 42, and the transmission gear 61 is connected by a chain 62. A motor 63 is also provided outside the steam-washing box 1 to drive the transmission gear 61 to rotate. Therefore, when in use, the motor 63 drives the transmission gear 61 to rotate, so that the transmission gear 61 drives one of the third guide rollers 4 to rotate, and the chain 62 drives the transmission gears 61 on the other third guide rollers 4 to rotate synchronously, thereby causing the cleaning liquid in the steam-washing box 1 to generate strong turbulence and improve the cleaning effect of the cloth.

[0050] The manner in which the motor 63 and the transmission gear 61 drive the other transmission gear 61 to rotate via the chain 62 is known to those skilled in the art and will not be described in detail here.

[0051] The connecting piece 43 is distributed in a spiral shape, and the diameter of the connecting piece 43 is the same as the diameter of the annular cylinder 411. The connecting piece 43 is symmetrically arranged from the middle of the third guide roller 4 to both ends, so that when the third guide roller 4 drives the cloth to rotate, it can play a flattening role to prevent the cloth from shifting. At the same time, the spiral connecting piece 43 is used for connection, which has more aeration space, makes the gas flow smoother, and can further improve the aeration effect.

[0052] The inclination angles of the blades 413 of the two adjacent groups of turbulence generators 41 on the third guide roller 4 are symmetrically arranged. Therefore, as the inclination angles of the blades 413 are adjusted synchronously, the rapid flow and turbulence formation of the cleaning liquid are promoted, thereby enhancing the collision and friction between the liquid and the surface of the cloth, and significantly improving the cleaning efficiency.

[0053] The thickness of the blade 413 gradually decreases from the middle to both ends, which can effectively guide the flow of the cleaning liquid and enhance the formation of turbulence. As the blade 413 extends toward both ends, the gradual decrease in thickness helps to reduce flow resistance, allowing the cleaning liquid to pass more smoothly.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
