Detailed Embodiments

[0034] In order to make the technical problems, technical solutions, and beneficial effects solved by the present application clearer, the following will further describe the present application in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] Please refer to Figures 1 to 7 , a multifunctional coating machine, including a frame body 1,

[0036] a coating platform 2, which is arranged on the frame body 1;

[0037] The traction device 3 is arranged on the frame body 1 and is located below the coating platform 2, and is used for continuously conveying the fabric 4 onto the coating platform 2;

[0038] The rotary tool rest device 5 is arranged on the frame body 1 and is located above the coating platform 2, and is used for evenly applying the coating on the fabric 4 passing through the coating platform 2;

[0039] The coating platform 2 includes a lifting U-shaped frame 21, a center roller 22, a lifting silver coating device 23, and a top knife device 24 which are located below the fabric 4 and are arranged in sequence along the moving path of the fabric 4.

[0040] A multifunctional coating machine of the present application can respectively realize floating knife coating, roll coating, silver coating, curtain fabric and airbag fabric coating processes by moving the rotary tool rest device located above the frame body to cooperate with the lifting U-shaped frame, the center roller, and the lifting silver coating device located on the coating platform, and then driving the fabric to move along the coating platform through the traction device, so as to meet the different process requirements of different customers.

[0041] Further, as a preferred implementation manner of this solution rather than a limitation, when the rotary tool rest device 5 moves to cooperate with the lifting U-shaped frame 21, it is a coating process mode; when the rotary tool rest device 5 moves to cooperate between the silver coating device 23 and the top knife device 24, it is a silver coating process mode.

[0042] In this embodiment, by moving the rotary tool rest device to cooperate with the lifting U-shaped frame or between the silver coating device and the top knife device, flexible switching between the coating process mode and the silver coating process mode is realized. In the coating process mode, the rotary tool rest device cooperates with the lifting U-shaped frame, and the coating can be evenly applied on the fabric, which is suitable for conventional coating treatment of the fabric. In the silver coating process mode, the rotary tool rest device moves to cooperate between the silver coating device and the top knife device, and the fabric can be silver-coated to meet the production requirements of special products. This design enables the coating machine to be quickly adjusted according to different process requirements, improving the adaptability and production efficiency of the equipment.

[0043] Further, as a preferred implementation manner of this solution rather than a limitation, the lifting silver coating device 23 includes a worm 231 connected to the output end of the motor, a screw 232 connected to the worm 231, and a cloth supporting plate 233 arranged at the top of the screw 232, and the forward or reverse rotation of the motor drives the cloth supporting plate 233 to rise or fall.

[0044] In this embodiment, when the motor rotates forward or backward, the worm drives the screw rod to rotate, causing the cloth support plate to rise or fall for preliminary debugging. Subsequently, through the downward pressure of the rotary tool rest device, the angle between the cloth and the rotary tool rest device is adjusted to achieve the controllability of the uniformity and thickness of silver coating, so as to meet the silver coating requirements of different products and optimize the silver coating effect.

[0045] Further, as a preferred implementation manner rather than a limitation of this solution, when in the silver coating process mode, the cloth support plate 233 rises or falls to achieve preliminary adjustment, and the rotary tool rest device 5 presses down or rises to gradually reduce or increase the angle formed at the contact between the cloth 4 and the rotary tool rest device 5.

[0046] Further, as a preferred implementation manner rather than a limitation of this solution, when in the coating process mode, the lifting U-shaped frame 21 rises or falls relative to the machine frame body 1 to achieve preliminary adjustment, and the rotary tool rest device 5 presses down to adjust the depth at which the rotary tool rest device 5 presses the cloth 4 onto the lifting U-shaped frame 21.

[0047] In this embodiment, the operator accurately adjusts the position preliminarily through the lifting U-shaped frame according to the thickness of the cloth and the requirements of the coating. Subsequently, the contact pressure between the cloth and the tool rest is adjusted by the downward pressure of the rotary tool rest device to ensure the uniformity and consistency of the coating. In addition, this adjustable design also helps to improve the adaptability of the coater, enabling it to handle different types and characteristics of cloth, thus expanding its application range.

[0048] Further, as a preferred implementation manner rather than a limitation of this solution, the top knife device 24 includes a gear box 241, a mounting seat 242 connected to the output end of the gear box 241, a rear cloth guiding roller 243 rotatably connected to the mounting seat 242, and a top knife 244 provided on the mounting seat 242. The gear box 241 drives the mounting seat 242 to rotate to adjust the angle at the contact between the top knife 244 and the cloth 4.

[0049] In this embodiment, the drive of the gearbox 241 enables the mounting seat 242 to rotate, thereby adjusting the angle at which the top knife 244 contacts the fabric 4. This design not only improves the uniformity and accuracy of coating, but also enhances the adaptability and flexibility of the equipment. By adjusting the contact angle between the top knife 244 and the fabric 4, it is possible to adapt to fabrics of different thicknesses and materials, ensuring the consistency and quality of the coating. For example, when processing thicker fabrics, the contact angle can be increased to increase the pressure, so that the coating can penetrate more evenly into the fabric; while when processing thinner fabrics, reducing the contact angle can reduce the pressure on the fabric and avoid damage during the coating process. In addition, this adjustable design also facilitates the use of the coater in different application scenarios. For example, when producing products such as sunshade fabrics and airbags, the settings of the top knife device 24 can be adjusted according to specific process requirements to achieve the best coating effect.

[0050] Further, as a preferred implementation manner rather than a limitation of this solution, the lifting silver coating device 23 further includes baffles 234 located on both sides of the fabric supporting plate 233, and a second water tank 235 is provided below the lifting silver coating device 23.

[0051] In this embodiment, by providing baffles on both sides of the fabric supporting plate, it is possible to effectively prevent the leakage of the coating slurry during the silver coating process. The setting of the second water tank can prevent the coating from dripping onto the fabric or the ground below, thereby avoiding the pollution of the coating quality and the production environment. When the coating in the second water tank is full, it can be manually removed and cleaned to ensure the normal operation of the coater and the cleanliness of the production environment, which helps to reduce the waste of the coating and improve the utilization rate of materials. Further embodiments may include installing an automatic sensing device in the second water tank 235 to automatically send a signal when the coating reaches a certain amount, reminding the operator to clean it, thereby further improving the automation level. In addition, it can be considered to add a coating or special material to the baffle 234 to improve its wear resistance and anti-pollution ability and extend its service life.

[0052] Further, as a preferred implementation manner rather than a limitation of this solution, the frame body 1 is provided with a slide rail 11 arranged in the front-rear direction. The rotary tool rest device 5 includes a first mounting table 51 slidably connected to the slide rail 11, a second mounting table 52 slidably connected to the first mounting table 51 in the vertical direction, a tool rest mounting seat 53 rotatably connected to the second mounting table 52, a first scraper 54 and a second scraper 55 provided on the tool rest mounting seat 53 and arranged along the rotation direction of the tool rest mounting seat 53, a first motor 56 for driving the first mounting table 51 to move back and forth along the slide rail 11, a second motor 57 for driving the second mounting table 52 to move up and down along the first mounting table 51, and a third motor 58 for driving the tool rest mounting seat 53 to rotate.

[0053] In this embodiment, by providing a slide rail on the frame body and enabling the rotary tool rest device to include a first mounting table slidably connected to the slide rail, a second mounting table slidably connected to the first mounting table in the vertical direction, a tool rest mounting seat rotatably connected to the second mounting table, and motors for respectively driving the first mounting table, the second mounting table, and the tool rest mounting seat to move or rotate, precise adjustment of the position and posture of the rotary tool rest device is achieved, thereby meeting the requirements of different coating processes for the position and angle of the doctor blade. The forward and backward movement of the first mounting table 51 along the slide rail 11, the up and down movement of the second mounting table 52 along the first mounting table 51, and the rotation of the tool rest mounting seat 53 together achieve precise positioning and control of the first doctor blade 54 and the second doctor blade 55. This design not only enables the coater to adapt to fabrics 4 of different thicknesses and characteristics, but also allows dynamic adjustment of the contact pressure and angle between the doctor blade and the fabric during the coating process, thereby optimizing the uniformity and quality of the coating.

[0054] Further, as a preferred implementation manner rather than a limitation of this solution, it further includes a slurry sweeping device 6 provided on the frame body 1 and located above the rotary tool rest device 5.

[0055] Further, as a preferred implementation manner rather than a limitation of this solution, the first doctor blade 54 and the second doctor blade 55 are respectively provided as a pointed knife and a round knife.

[0056] In this embodiment, by respectively providing the first doctor blade and the second doctor blade as a pointed knife and a round knife, adaptability and optimized processing of different types and characteristics of coating materials can be achieved. The pointed knife and the round knife have their own unique shapes and edge characteristics, and can provide different scraping effects for different coating materials.

[0057] Specifically, the pointed knife usually has a sharp edge and a small contact area, and is suitable for scraping coating materials with high viscosity and poor fluidity, such as adhesives or sealants. The sharp edge of the pointed knife can easily penetrate the surface of the coating material to achieve fast and uniform scraping, while the small contact area can reduce the shear and damage to the coating material.

[0058] The round knife usually has a relatively blunt edge and a large contact area, and is suitable for scraping coating materials with low viscosity and good fluidity, such as paints or inks. The blunt edge of the round knife can reduce the cutting and scratching of the coating material, while the large contact area can provide better scraping pressure and covering effect.

[0059] Further, as a preferred implementation manner rather than a limitation of this solution, the traction device 3 includes a pressure roller 31, a traction roller 32, a tension roller 33, a bending roller 34, and a front side guiding roller 35 sequentially arranged along the moving path of the fabric 4.

[0060] In this embodiment, by arranging a cloth pressing roller, a traction roller, a tension roller, a bending roller and a front side cloth guiding roller in the traction device and reasonably arranging their order and positions, stable traction and transmission of the cloth can be achieved, and appropriate tension control can be provided to meet the requirements of the coating process for the flatness and consistency of the cloth.

[0061] Further, as a preferred implementation manner rather than a limitation of this solution, a water scraping device 7 is further included and is in contact with the rotating surface of the central roller 22 on the frame body 1.

[0062] In this embodiment, by arranging a water scraping device in contact with the rotating surface of the central roller on the frame body, timely cleaning of the excess coating or moisture adhering to the central roller can be achieved, thereby avoiding interference and influence on the subsequent coating process. The central roller is an important component in the coater for supporting and transmitting the cloth, and the cleanliness of its surface directly affects the quality and uniformity of the coating. When a part of the contact surface of the central roller is immersed in the water in the first water tank, it may cause excessive moisture or diluted coating to adhere to its surface. If not cleaned in time, these excess moisture or coating may be transferred to the cloth during the coating process, resulting in problems such as dilution, foaming or unevenness of the coating.

[0063] Further, as a preferred implementation manner rather than a limitation of this solution, a first water tank 8 is provided below the central roller 22 for a part of it to sink into.

[0064] In this embodiment, an effective coating dilution and control mechanism is provided for the coater. This design enables a part of the surface of the central roller 22 to contact the liquid in the water tank, thereby achieving dilution of the coating, which is crucial for controlling the thickness and uniformity of the coating.

[0065] Further, as a preferred implementation manner rather than a limitation of this solution, by arranging a motor and a feedback device and setting their parameters and performing PLC programming, precise control of the rotary tool rest device is achieved, enabling it to automatically find the zero position according to a preset program and complete horizontal, vertical and rotational movements. Specifically, the motor, as an actuator, is responsible for providing the power required by the rotary tool rest device, while the feedback device is used to monitor and feedback the position and status information of the rotary tool rest device in real time. Through PLC programming, appropriate control parameters and logical relationships can be set according to the process requirements and equipment characteristics, enabling the motor to make corresponding adjustments and controls based on the information of the feedback device, thereby achieving precise positioning and motion control of the rotary tool rest device. This design not only improves the automation degree and production efficiency of the equipment, but also enhances the stability and reliability of the equipment.

[0066] Furthermore, as a preferred implementation manner rather than a limitation of this solution, the width distance in the width direction of the automatic slurry sweeping device can be adjusted according to the width change of the fabric made by the customer, so as to meet the requirements of coating fabrics with different widths on the same coating machine. Since there may be certain variations in the width of the fabric, or fabrics with different widths need to be coated on the same coating machine, the width of the slurry sweeping device also needs to be adjusted accordingly to match the width of the fabric. These width adjustments can be achieved through the electrical control in the slurry sweeping device. Specifically, the electrical control can automatically adjust the width of the slurry sweeping device according to the width information of the fabric to keep it consistent with the width of the fabric, thereby ensuring that the slurry sweeping device can effectively remove the excess coating on the fabric and improve the coating quality. This design not only improves the adaptability and flexibility of the equipment, but also enhances the automation degree and production efficiency of the equipment.
