Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coating devices, in particular to a continuous coating device with adjustable width and a control method thereof. BACKGROUND

[0002] With the continuous development of global science and technology and the rapid progress of manufacturing industry, especially under the background of the increasing environmental awareness, the textile industry is facing the dual challenges of environmental requirements and production efficiency. Coating device is a common method for producing functional fabrics. The earliest coating device usually cannot realize continuous coating and cannot automatically adjust the coating width, and has many shortcomings such as low production efficiency, poor coating consistency, high production cost, poor process stability, etc. In recent years, continuous coating devices have been gradually developed, which have many advantages. First, the coating materials commonly used in continuous coating process can be water-based or environmentally friendly, which greatly reduces the use of organic solvents and is conducive to environmental protection and ecological balance. Second, the waste generated in the continuous coating process is relatively small, reducing material waste and pollution. In addition, continuous coating does not need to start and stop the production line repeatedly, and the energy consumption is relatively low. Especially with the application of new energy-efficient equipment, it can further reduce energy consumption and carbon emissions, in line with the environmental protection concept of energy saving and emission reduction. Finally, continuous coating has outstanding product quality, and the coating layer is more likely to form a uniform coating structure in continuous operation, so the products of continuous coating often have better surface smoothness, adhesion and durability, which can meet the needs of consumers for high-quality coated products.

[0003] Although the continuous coating device has improved the problems of coating efficiency, consistency and process stability to some extent, it still has certain limitations. The coating width used in most current continuous coating devices is usually fixed and difficult to adjust according to the needs of different products. This fixed width design limits the adaptability of the device to different product specifications, affecting the flexibility and production efficiency in the actual production process. Therefore, there is an urgent need for a coating device that can adjust the coating width in real time and ensure continuous production. SUMMARY

[0010] As a further improvement, a blowing mechanism is arranged between the coating mechanism and the winding roller, which is used to dry the coating on the surface of the base fabric.

[0011] As a further improvement, the slurry box specifically comprises a box body, the mounting slot is a columnar slot recessed towards the inside of the box body in the horizontal direction, the upper end of the mounting slot is provided with an inlet in communication with the inside of the box body, and the lower end of the mounting slot is provided with an outlet not in communication with the inside of the box body.

[0012] The feeding mechanism specifically comprises a cartridge, which is a columnar body matched with the mounting slot, a plurality of storage bins are arranged at intervals on the outer periphery of the cartridge, an adjusting motor is arranged at one end of the cartridge away from the scraping mechanism through a connecting shaft, and the adjusting motor rotates according to the control signal sent by the coating control unit.

[0013] The slurry in the box body enters the storage bin of the cartridge through the inlet, and falls from the outlet onto the base fabric after the storage bin containing the slurry corresponds to the outlet with the rotation of the cartridge.

[0014] As a further improvement, the thickness scraper is connected with a lifting screw rod, and the lifting screw rod adjusts the height of the thickness scraper according to the control signal sent by the coating control unit.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features.

[0040] A continuous coating device with adjustable width, comprising:

[0041] A temperature-controlled platform 1;

[0042] A conveying mechanism, comprising a pair of auxiliary wheels 31 arranged at the position of the feeding port 222 of the temperature-controlled platform 1, and a winding roller 32 arranged at the position of the discharging port 223 of the temperature-controlled platform 1, the base fabric 0 passing between the two auxiliary wheels 31 and winding around the outer periphery of the winding roller 32;

[0043] A coating mechanism 2 arranged on the temperature-controlled platform 1 and located between the auxiliary wheels 31 and the winding roller 32, the coating mechanism 2 comprising a rack 11, a slurry box 22 being detachably arranged on the rack 11, a plurality of mounting grooves 221 being arrayed on the slurry box 22, a feeding mechanism 21 with adjustable feeding amount being detachably arranged in each mounting groove 221, a thickness scraper 24 vertically adjustable and a pair of width scrapers 23 adjustably approaching / away from each other being arranged on the side of the rack 11 away from the feeding mechanism 21, specifically, a plurality of feeding mechanisms 21 are sequentially numbered 1, 2, 3...N, wherein N is a natural number not less than 2, and the corresponding regions of the base fabric 0 are correspondingly numbered.

[0044] A control module is arranged on the coating device, and the control module comprises a speed control unit, a coating control unit and a temperature control unit, the speed control unit is connected with the winding roller 32, and the speed control unit is used for sending a corresponding cloth conveying speed signal to adjust the winding speed of the winding roller 32; the coating control unit is connected with the coating mechanism 2, and the coating control unit is used for controlling the height of the thickness scraper 24, the interval between the two width scrapers 23 and the feeding speed of the feeding mechanism 21; and the temperature control unit is connected with the temperature control platform 1, and the temperature control unit is used for controlling the working temperature of the temperature control platform 1 as a whole.

[0045] Specifically, the thickness scraper 24 is a long strip-shaped scraper perpendicular to the conveying direction of the base fabric 0, and the two width scrapers 23 are flexible pad scrapers in the same direction as the conveying direction of the base fabric 0, and the lower end surface of the width scraper 23 is in close contact with the upper end surface of the base fabric 0.

[0046] In order to improve the adjustment accuracy of the coating width and avoid that the coating cannot be limited by the width scrapers 23 because the coating falls outside the two width scrapers 23, as a further improvement, the two width scrapers 23 are gradually inclined towards each other in the direction close to the thickness scraper 24.

[0047] As a further improvement, the angle between the inclination angle of the two width scrapers 23 and the conveying direction of the base fabric 0 is not more than 5°.

[0048] The feeding mechanism 21 at the central axis position of the base fabric 0 must be in an open state, so that coating is prone to accumulate near the central axis position of the base fabric 0, and coating is prone to be insufficient away from the central axis position. In order to prevent the central axis position from accumulating coating and better supplement the areas on both sides, as a further improvement, the side surface of the thickness scraper 24 close to the auxiliary wheel 31 gradually thins towards both sides.

[0049] As a further improvement, the coating mechanism 2 and the winding roller 32 are further provided with a blowing mechanism 4, and the blowing mechanism 4 is used for air drying the coating on the surface layer of the base fabric 0.

[0050] In order to ensure that when the coating width increases, a single scraping mechanism is not enough to coat the coating to the rated width area, the coating mechanism 2 and the blowing mechanism 4 are further provided with a secondary scraping mechanism, and the structure of the secondary scraping mechanism is the same as that of the scraping mechanism. When the secondary scraping mechanism is provided, the height of the thickness scraper 24 in the scraping mechanism is 1-1.5 mm higher than the rated height.

[0051] As a further improvement, the slurry box 22 specifically comprises a box body, the mounting groove 221 is a columnar groove recessed towards the interior of the box body in a horizontal direction, an upper end of the mounting groove 221 is provided with a feeding port 222 in communication with the interior of the box body, and a lower end of the mounting groove 221 is provided with a discharging port 223 not in communication with the interior of the box body.

[0052] The feeding mechanism 21 specifically comprises a material box 211, the material box 211 is a columnar body matched with the mounting groove 221, a periphery of the material box 211 is provided with a plurality of storage compartments 2111 at intervals, and an end of the material box 211 away from the scraping mechanism is provided with an adjusting motor 213 through a connecting shaft 212, the adjusting motor 213 rotates according to a control signal sent by the coating control unit.

[0053] The slurry in the box body enters the storage compartment 2111 of the material box 211 through the feeding port 222, and falls onto the base fabric 0 from the discharging port 223 after the storage compartment 2111 filled with the slurry corresponds to the discharging port 223 with the rotation of the material box 211.

[0054] As a further improvement, the thickness scraper 24 is connected with a lifting lead screw 24a, the lifting lead screw 24a adjusts the height of the thickness scraper 24 according to a control signal sent by the coating control unit.

[0055] As a further improvement, the two width scrapers 23 are arranged on the rack 11 through a double-head screw 23a, the two width scrapers 23 abut against the thickness scraper 24, and the double-head screw 23a adjusts the spacing between the two width scrapers 23 according to a control signal sent by the coating control unit.

[0056] The application further provides a control method of the continuous coating device with adjustable width, which is applied to any one of the continuous coating devices with adjustable width and comprises the following steps:

[0057] S1. Obtain the cloth processing information;

[0058] S2. Number the plurality of feeding mechanisms 21 in sequence as 1, 2, 3...N, wherein N is a natural number not less than 2, and number the corresponding regions of the base fabric 0 correspondingly;

[0059] S3. Determine the corresponding relationship between the coating width information in the cloth processing information and the numbered regions of the base fabric 0, send corresponding control signals to the coating mechanism 2 according to the corresponding relationship, and keep continuous coating processing.

[0060] As a further improvement, the S1 specifically comprises the following steps:

[0061] S1. obtaining the coating thickness information and the coating width information in the cloth processing;

[0062] S2. according to the cloth processing information, the processing process of the cloth is divided into a stable processing section, a width-reducing processing section, and a width-increasing processing section. After the base cloth 0 passes through the width-reducing processing section or the width-increasing processing section, it enters the stable processing section.

[0063] As a further improvement, the S3 specifically includes the following working conditions:

[0064] A301. In the stable processing section, the middle axis of the region to be processed of the base cloth 0 is taken as the symmetry line, and the rotation directions of the adjusting motors 213 of the feeding mechanisms 21 on both sides are opposite, i.e., the tangent lines of the lowermost ends of the feeding mechanisms 21 point to the middle axis of the base cloth 0.

[0065] A302. When entering the width-reducing processing section from the stable processing section, the coating control unit sends a speed-reducing signal to the winding roller 32, and sends a speed-reducing signal to the adjusting motor 213 of the feeding mechanism 21 not located in the region to be processed of the base cloth 0 in the next processing section when the base cloth 0 has a length of 10-30 cm entering the next processing section, and the base cloth 0 has a length of 2-5 cm entering the next processing section to achieve shutdown. After passing through the width-reducing processing section, an acceleration signal is sent to the winding roller 32 until the rated transmission speed is restored.

[0066] A303. When entering the width-increasing processing section from the stable processing section, the coating control unit sends a speed-reducing signal to the winding roller 32, and sends a direction-changing signal to the two adjusting motors 213 adjacent to the two most lateral adjusting motors 213 of the base cloth 0 in the current processing section, so that the tangent lines of the lowermost ends of the feeding mechanisms 21 corresponding to the two adjusting motors 213 are all opposite to the middle axis of the base cloth 0. When the base cloth 0 has a length of 2-5 cm entering the next processing section, the coating control unit sends an acceleration signal to the winding roller 32, and when the base cloth 0 has a length of 0.5-1 cm entering the next processing section, a start signal is sent to the adjusting motor 213 of the feeding mechanism 21 additionally added in the next processing section and located in the region to be processed of the base cloth 0. After the initial 10-30 cm length of the next processing section is processed, a rotating signal is sent to the two reversed adjusting motors 213 to adjust the rotation direction to be the same as that of the adjusting motor 213 on the same side, and the winding roller 32 restores the rated transmission speed.

[0067] To further improve the applicability of the present application, the width-reducing processing section is divided into a continuous width-reducing processing section and a sudden width-reducing processing section.

[0068] When entering the sudden width-reducing processing section from the stable processing section, the adjustment is performed according to the working condition A302.

[0069] When transitioning from the stable processing section to the continuous reduction processing section, the process enters condition A302a:

[0070] When the base fabric 0 has 10-30cm of length left before entering the next processing section, the coating control unit sends a deceleration signal to the winding roller 32. At the same time, it judges the feeding mechanism 21 corresponding to the start and end positions of the continuous shrinking section. If the feeding mechanism 21 corresponding to the end position is only 2 fewer than the feeding mechanism 21 corresponding to the start position, then a deceleration signal is sent to the two feeding mechanisms 21. When the base fabric 0 reaches the end position when there is 1 / 3 of the total length of the continuous shrinking processing section left, the machine stops. During the transmission process, the two width scrapers 23 gradually move towards each other with the double-headed screw 23a.

[0071] If the feeding mechanism 21 at the end position is at least four fewer than the feeding mechanism 21 at the beginning position, then the feeding mechanisms 21, which are symmetrically arranged in pairs along the central axis of the base fabric 0, are grouped into groups 1A, 2A...NA, where N is a natural number not less than 2. The position node where the area corresponding to group 1A completely falls into the processing area is defined as the starting point of group 1A, and the position node where the area corresponding to group 1A does not fall into the processing area is defined as the ending point of group 1A, and so on. When entering the starting point of group 1A, a deceleration signal is sent to the two feeding mechanisms 21 of group 1A, and the machine stops when the base fabric 0 reaches the ending point of group 1A at a position where 1 / 3 of the total length from the starting point to the ending point of group 1A is still present. During the transmission process, the two width scrapers 23 gradually move towards each other along with the double-headed screw 23a. Similarly, subsequent feeding mechanism groups 21, such as group 2A, complete the change in coating width using the same adjustment method.

[0072] As a further improvement, the following steps are also included:

[0073] S4. Based on the base fabric 0 transmission speed signal in the control signal, a corresponding temperature control signal is sent to the blower mechanism 4. When the base fabric 0 transmission speed, i.e. the rotation speed of the winding roller 32, decreases, the blower mechanism 4 adjusts accordingly downwards, and vice versa.

[0074] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
