Description

Technical Field

[0001] The invention belongs to the technical field of clothing fabric production, and in particular relates to a bacterial liquid supply device for antibacterial cashmere fabric. Background Art

[0002] Cashmere fiber is a porous material. After the fibers are stacked and woven to form a multi-layer body, its fabric structure is easy to absorb fungi. In addition to the harm to the human body, the parasites will also contaminate the fibers, so antibacterial cashmere fabrics came into being. Antibacterial cashmere fabrics are cashmere fabrics with added antibacterial functions. They can inhibit the growth of bacteria and fungi, keep the fabrics clean and hygienic, and extend the service life of the fabrics. It is suitable for making various clothing and textiles that require antibacterial functions, such as bed sheets, quilt covers, work clothes and underwear for hospitals and hotels. In addition, due to its excellent comfort and warmth retention, antibacterial cashmere fabrics are also widely used in the field of high-end clothing.

[0003] During the preparation process of antibacterial cashmere fabric, the antibacterial liquid needs to be transported to the surface of the fabric through a special liquid supply device. In the prior art, the antibacterial liquid is generally coated on the surface of the fabric by immersion. However, due to the particularity of cashmere fabric, too much antibacterial liquid will affect the feel, appearance and performance of the cashmere fabric. Therefore, it is necessary to control the spraying amount to ensure the uniform distribution and proper use of the antibacterial liquid. However, an ordinary coating roller is used and a simple leakage hole is set on the coating roller. This makes it difficult to ensure that the antibacterial liquid is evenly distributed throughout the cashmere fabric, and the coating liquid supply amount is difficult to control. In addition, the coverage and permeability of the antibacterial liquid are weak, and it is difficult for the antibacterial liquid to better penetrate into the fabric fibers. The bonding force between the antibacterial liquid and the fabric is poor, and it is difficult to maintain activity in the fabric for a longer time. At the same time, the entire coating roller is difficult to adapt to the coating of irregular cashmere fabrics, and the waste of antibacterial liquid is relatively serious.

DETAILED DESCRIPTION

[0032] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0033] Embodiment 1

[0034] In order to solve the problem that the existing technology generally adopts the method of immersion to apply the antibacterial liquid to the surface of the fabric, but due to the particularity of cashmere fabric, too much antibacterial liquid will affect the feel, appearance and performance of the cashmere fabric, and the ordinary coating roller is used, and a simple leak hole is set on the coating roller, which makes it difficult to ensure that the antibacterial liquid is evenly distributed to all parts of the cashmere fabric, and the coating liquid supply is difficult to control. Please refer to Figure 1-Figure 2 , Figure 4-Figure 7 The present invention provides a bacterial liquid supply device for antibacterial cashmere fabrics, comprising a workbench 2 for fixing cashmere fabrics and a coating assembly 3 located above the workbench 2 and used for applying antibacterial liquid to the cashmere fabrics. A liquid supply box 7 for supplying antibacterial liquid to the coating assembly 3 is provided on the side of the coating assembly 3, and a material barrel 8 for storing antibacterial liquid and connected to the liquid supply box 7 is provided above the liquid supply box 7. The antibacterial liquid is accurately supplied to the coating assembly 3 through the liquid supply box 7, and then the antibacterial liquid is evenly applied to all parts of the cashmere fabric through the special structure of the coating assembly 3.

[0035] A pressure plate 701 with a T-shaped cross section is provided in the liquid supply box 7, and a liquid outlet pipe 702 is provided on the side of the liquid supply box 7. The antibacterial liquid in the liquid supply box 7 is pressed out through the pressure plate 701, and the antibacterial liquid falls into the coating component 3 through the liquid outlet pipe 702.

[0036] In order to realize automated coating, a support platform 1 is provided under the workbench 2, and movable modules 101 are fixedly provided at the edges of both sides of the top of the support platform 1. A gantry 4 for driving the horizontal movement of the coating component 3 is slidably provided between the two movable modules 101, and an electric lifting rod 401 for driving the coating component 3 to move up and down is fixedly provided on the top of the crossbeam of the gantry 4.

[0037] The coating assembly 3 includes a coating body 301 and a plurality of balls 302 evenly distributed in a lattice shape and rollingly arranged at the bottom of the coating body 301, the balls 302 are used to apply antibacterial liquid to the cashmere fabric; a plurality of liquid storage tanks 301a evenly distributed in a lattice shape and corresponding one to one with the balls 302 are arranged on the top of the coating body 301, connecting holes 301b for communication are arranged between adjacent liquid storage tanks 301a, and a liquid outlet hole 301c for supplying antibacterial liquid to the balls 302 is arranged at the bottom of the liquid storage tank 301a. During application, the electric lifting rod 401 drives the coating component 3 to descend, so that the ball 302 contacts the cashmere fabric, and then the moving module 101 drives the coating component 3 to move horizontally. At this time, the ball 302 in contact with the cashmere fabric rolls, and the antibacterial liquid in the liquid storage tank 301a falls onto the ball 302 through the liquid outlet 301c, and is applied to the cashmere fabric through the ball 302. The ball 302 that is not in contact with the cashmere fabric does not roll, so the antibacterial liquid will not drip, so that the coating component 3 can adapt to the irregular cashmere fabric. The application of antibacterial liquid to the cashmere fabric will not cause waste of antibacterial liquid, and the overall application amount of the antibacterial liquid can be better controlled, so that accurate antibacterial liquid application can be performed. At the same time, when applying, the surface of the cashmere fabric is rolled by the ball 302, which can improve the application effect of the antibacterial liquid. When the ball 302 rolls on the surface of the cashmere fabric, the surface of the fabric is smoother, wrinkles and uneven areas are reduced, and the coverage and permeability of the antibacterial liquid are improved. At the same time, the pressure and friction during the rolling process can make the antibacterial liquid better penetrate into the fabric fibers and form a stronger bonding force with the fabric.

[0038] The coating assembly 3 further includes a cover plate 303 located on the top of the coating body 301 and a rubber plug 304 movably inserted into the liquid storage tank 301a. A liquid inlet is provided on the cover plate 303. The antibacterial liquid enters the liquid storage tank 301a through the liquid inlet. Since each liquid storage tank 301a is connected through the connecting hole 301b, it can be ensured that each liquid storage tank 301a has the same liquid level of antibacterial liquid, and based on the specifications of the cashmere fabric, a suitable number of liquid storage tanks 301a can be opened, and the remaining liquid storage tanks 301a can be closed by the rubber plug 304.

[0039] Embodiment 2

[0040] On the basis of the first embodiment, in order to further improve the coating effect of the coating component 3, the antibacterial liquid can better penetrate into the fabric fiber, such as Figure 8As shown, the coating component 3 also includes an ultrasonic generator 305 located on the side of the coating body 301 and a vibration unit 306 located in the internal cavity of the coating body 301 and abutting against the ultrasonic generator 305 for driving the ball 302 to vibrate; the vibration unit 306 includes a main vibration plate 306a abutting against the ultrasonic generator 305 and a plurality of branch vibration plates 306c abutting against the main vibration plate 306a, both sides of the main vibration plate 306a are provided with a plurality of second springs 306b fixed in the internal cavity of the coating body 301, and both sides of the branch vibration plate 306c are provided with a plurality of third springs 306d fixed in the internal cavity of the coating body 301; the branch vibration plate 306c abuts against the ball 302, and each ball 302 is surrounded by four branch vibration plates 306c evenly distributed along the circumference.

[0041] When in use, the ultrasonic generator 305 drives the main vibration plate 306a to vibrate at high frequency, the main vibration plate 306a drives each branch vibration plate 306c to vibrate at high frequency, each branch vibration plate 306c drives its own ball 302 to vibrate at high frequency, and the ball 302 drives the antibacterial liquid on its surface to vibrate at high frequency, thereby improving the dispersion and uniformity of the antibacterial liquid, thereby enhancing the covering effect of the antibacterial liquid and avoiding the accumulation and uneven distribution of the antibacterial liquid.

[0042] Embodiment 3

[0043] On the basis of the first and second embodiments, in order to solve the problem that the existing fabric bacterial liquid supply device is difficult to supply the corresponding antibacterial liquid based on the weight of the fabric, the use of a relatively complex sensor system is relatively expensive, such as Figure 1-Figure 4 As shown, it also includes a weighing assembly 5 located at the bottom center of the support platform 1 for collecting the weight of the cashmere fabric, and a lever mechanism 6 for amplifying gravity and feeding it back to the liquid supply box 7 is provided on the side of the weighing assembly 5. The weight of the cashmere fabric can be fed back to the lever mechanism 6 through the weighing assembly 5, and the lever mechanism 6 amplifies the gravity and feeds it back as a thrust in the liquid supply box 7. The antibacterial liquid in the liquid supply box 7 is pushed into the coating assembly 3 through the thrust. The whole system can adapt to the weight of the fabric and has a simple structure.

[0044] The top surface of the workbench 2 is provided with a plurality of vacuum adsorption holes evenly distributed in a lattice shape; movable rods 201 that are movably inserted into the support platform 1 are fixedly provided at the four corners of the bottom of the workbench 2, and a first spring 202 is sleeved on the movable rod 201 between the support platform 1 and the workbench 2. When the cashmere fabric is placed on the workbench 2, the fabric presses down the workbench 2 under the action of gravity, and the first spring 202 is compressed at this time. When the cashmere fabric is removed, the workbench 2 and the first air box 501 are reset under the reset action of the first spring 202.

[0045] The weighing assembly 5 includes a first air box 501 fixedly arranged at the bottom center of the support platform 1 and an air supply pipe 503 located at the bottom of the first air box 501 and connected thereto; the end of the piston rod in the first air box 501 passes through the support platform 1 and is fixedly connected to the workbench 2, and a locking unit 502 for locking the movement of the piston rod of the first air box 501 is provided at the top of the support platform 1; the locking unit 502 includes a sleeve 502a fixedly arranged at the top of the support platform 1 and used to be sleeved on the outside of the piston rod of the first air box 501, and an electric push rod 502b for pressing against the piston rod of the first air box 501 is provided on the side of the sleeve 502a. The top bracket of the cover plate 303 is provided with a limit unit 307 for adjusting the state of the locking unit 502; the limit unit 307 includes a metal contact piece 307a and an annular magnetic attraction plate 307b located around the metal contact piece 307a, and another metal piece matched with the metal contact piece 307a and another magnet matched with the magnetic attraction plate 307b are provided on the side of the liquid supply box 7, and the liquid supply circuit is connected through the contact between the metal contact piece 307a and the other metal piece to open the locking unit 502. The setting of the limit unit 307 and the locking unit 502 can ensure that when the coating component 3 is pushed to the side of the liquid supply box 7, the antibacterial liquid will drip from the liquid supply box 7, and the opening and closing of the locking unit 502 can be automatically realized, thereby improving the processing efficiency and accuracy.

[0046] In order to overcome the greater liquid resistance with a smaller gravity and improve the sensitivity of the entire weighing system, the lever mechanism 6 includes a support 601 and a lever body 602 hinged in the support 601; a second air box 603 and a third air box 604 are respectively provided on the sides of both ends of the lever body 602, and the piston rod end in the second air box 603 and the piston rod end in the third air box 604 are respectively hinged to the two ends of the lever body 602, the second air box 603 is connected to the first air box 501 through the air supply pipe 503, and the piston in the third air box 604 is fixedly connected to the pressure plate 701.

[0047] When in use, the coating component 3 is pushed to the side of the liquid supply box 7 until the metal contact piece 307a contacts another metal piece, the liquid supply circuit is turned on and the locking unit 502 is opened, and the cashmere fabric is placed on the workbench 2. Under the action of gravity, the fabric presses down the workbench 2, and drives the piston in the first air box 501 to press down, and presses the gas into the second air box 603. The piston in the second air box 603 moves immediately, and drives the piston rod to move. The piston rod drives one end of the lever body 602 to move. At this time, the lever body 602 rotates, and the other end of the lever body 602 drives the piston in the third air box 604 to move. The piston in the third air box 604 also drives the pressure plate 701 to move, and the antibacterial fluid in the liquid supply box 7 is pressed out.

[0048] The above-mentioned embodiment only expresses one implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
