Description

Technical Field

[0001] The present invention relates to the technical field of coating equipment, and more particularly to a multi-layer continuous coating equipment. Background Art

[0002] Coating equipment is mainly used for fabric surface coating process production. This equipment is a device that applies a layer of glue, paint or ink on the rolled substrate and finally rewinds it.

[0003] When modern fabrics require multiple layers of coating, it is necessary to wait for the first layer of coating to dry before applying the second coating. Therefore, a drying device is required behind each coating roller. PUR hot melt adhesive cures slowly and has high viscosity, so it is necessary to increase the temperature inside the drying device or set up multiple drying devices, resulting in a larger space required for the complete equipment. If the hot melt adhesive comes into contact with other rollers or objects during the coating process on the coating roller, it will affect the viscosity and flatness of the hot melt adhesive, affect the quality of the auxiliary glue on the coating roller, and affect the coating quality. In addition, during the use of the equipment, the thickness of the coated fabrics is different. If the same temperature is used to solidify the glue, the glue cannot be fixed for thicker fabrics, and the glue will over-cure and crack for thinner fabrics.

[0018] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0019] A multi-layer continuous coating device, such as Figure 1 、 Figure 2 and Figure 6As shown, it includes a body 1, and the top surface of the body 1 is rotatably connected to a unwinding roller 2, so that the cloth is lowered for coating. The conveying direction of the cloth on the unwinding roller 2 is perpendicular to the ground, and the cloth can be coated and cured at the same time during the downward movement of the cloth, so that there is no need to add additional special equipment to achieve the curing of the glue, thereby reducing the floor space of the equipment. The side of the unwinding roller 2 close to the ground is sequentially provided with a glue coating roller 1 3 and a glue coating roller 2 4, which are driven to rotate by a motor 3. The positions of the glue coating roller 1 3 and the glue coating roller 2 4 are fixed, so that the glue can be coated in the process of the cloth moving downward. When the glue is applied to the fabric, the moving direction of the fabric is set to be perpendicular to the ground. When external dust and impurities fall on the fabric, they will roll down under their own gravity until they fall to the ground, preventing the impurities from staying on the fabric for a long time and solidifying on the fabric along with the glue. The glue-applying roller 1 3 and the glue-applying roller 2 4 are facing the fabric, preventing other rollers or objects from contacting the glue-applying roller 1 3 and the glue-applying roller 2 4 and contaminating the glue. The lower glue roller 1 5 and the lower glue roller 2 6 are fixedly connected between the glue-applying roller 1 3 and the unwinding roller 2, and between the glue-applying roller 1 3 and the glue-applying roller 2 4, respectively. The central axes of the lower glue roller 1 5 and the lower glue roller 2 6 are both located at the glue-applying roller 1 3 is on the side away from the cloth. Since the glue roller 3 and the glue roller 2 4 are against the cloth, if the lower glue roller 5 is set on the side of the glue roller 3 close to the cloth, the glue dripping on the glue roller 3 will also partially drip onto the cloth. At this time, the glue will be distributed in a linear shape and drip downwards, and it needs to be scraped flat again later, which affects the work efficiency. The lower glue roller 5 is set on the side of the glue roller 3 and away from the cloth. Therefore, the glue dripping from the lower glue roller 5 will first adhere to the side of the glue roller 3 away from the cloth, and then the glue will be applied to the cloth by the glue roller 3, ensuring the uniformity of the coating. The lower glue roller 5 and the lower glue roller 2 6 are close to the ground. A plurality of glue dripping tubes 13 are arranged in an array on one side to reduce the distance between the lower glue roller 5 and the glue coating roller 3, so as to avoid the glue dripping on the outer wall of the glue coating roller 3 and splashing under the force. The glue dripping tubes 13 arranged in the array can ensure that the outer wall of the glue coating roller 3 can be evenly coated with glue. The distance between adjacent glue dripping tubes 13 is less than the diameter of the glue dripping tube 13, so as to avoid the situation where there is no glue on the glue coating roller 3 located between the adjacent glue dripping tubes 13 due to the large gap between the adjacent glue dripping tubes 13. One end of the glue coating roller 3 is provided with a guide tube connected to the interior thereof, and glue is continuously added to the glue coating roller 3 through the setting of the guide tube.

[0020] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, a connecting plate 7 is provided between the glue coating roller 13 and the glue coating roller 24, and a receiving box 14 is fixedly connected to the top surface of the connecting plate 7 near the glue coating roller 13. The receiving box 14 is used to receive the glue dripping from the glue coating roller 3 to avoid waste and environmental impact caused by direct dripping of the glue. The bottom surface of the connecting plate 7 is fixedly connected to the lower glue roller 26, and a guide groove 15 passing through the connecting plate 7 is provided on the receiving box 14. The guide groove 15 located inside the connecting plate 7 is connected to the glue dripping tube 13 of the lower glue roller 26, so that the glue collected in the receiving box 14 will drip from the receiving box 14 to the connecting plate 7, and then drip from the connecting plate 7. It falls into the lower glue roller 2 6, and finally the glue is coated on the glue coating roller 2 4, so as to save the glue that needs to be added during the coating process. The inner top surface of the receiving box 14 is set as an inclined surface inclined toward the guide groove 15. The setting of the inclined surface can achieve the guidance of the glue, and avoid a large amount of glue accumulating in the receiving box 14, which leads to insufficient glue entering the lower glue roller 2 6. The two side walls in the width direction of the receiving box 14 are fixedly connected with a heating plate 1, and a number of heating plates 2 are fixedly connected to the connecting plate 7. The setting of the heating plate 1 and the heating plate 2 can avoid the glue solidifying when it is cold, thereby ensuring the stable flow of the glue.

[0021] like Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown, one end of the lower glue roller 2 6 is provided with an addition tube 16 for filling a diluent therein, so that the viscosity of the glue applied on the cloth for the second time is less than the viscosity of the glue applied on the cloth by the glue roller 1 3. The diluent can be selected from high melting point wax or resin to reduce the initial adhesion of the hot melt adhesive. Since the applied glue is PUR hot melt adhesive, heating wires need to be added to the glue roller 1 3 and the glue roller 2 4 to ensure that the hot melt adhesive dripping on the glue roller 1 3 and the glue roller 2 4 is in liquid state. Since the glue roller 2 4 applies glue after the glue roller 1 3, the glue roller 1 3 can firmly adhere the higher viscosity glue to the cloth, and the low viscosity glue applied for the second time can better fill the unevenness of the first glue application, thereby ensuring the uniformity of the coating. At the same time, when the low viscosity glue is applied on the cloth, it will not In order to prevent the glue liquid applied for the first time from being peeled off from the fabric due to its own high viscosity, a stirring roller 17 for mixing the glue liquid and the diluent is connected to the lower glue roller 26, and the stirring roller 14 is driven to rotate by the motor 5. The adding tube 16 is set above the stirring roller 17, so that the diluent entering the lower glue roller 26 will drip downward, and thus pass through the stirring roller 17 to mix it with the glue liquid evenly, so as to ensure that the glue liquid attached to the glue roller 24 has been evenly mixed, thereby ensuring the coating quality. A receiving box 2 18 is placed on the side of the lower glue roller 26 close to the ground. The widths of the receiving box 14 and the receiving box 2 18 are both larger than the widths of the glue roller 1 3 and the glue roller 2 4, and the receiving box 14 and the receiving box 2 18 are both located directly below the glue roller 1 3 and the glue roller 2 4, ensuring that both can collect the glue liquid stably.

[0022] like Figure 2 、 Figure 3 and Figure 6As shown, a scraper 8 and a thermostat 9 are provided on the side of the connecting plate 7 close to the cloth. The scraper 8 is provided on the side of the thermostat 9 away from the ground, so that the scraper 8 can further flatten the glue applied on the cloth to avoid the uneven surface of the cloth after curing. Since the applied glue is PUR hot melt adhesive, the isocyanate group in the PUR hot melt adhesive reacts with moisture in the air to generate a polyurea structure and release carbon dioxide to form a cross-linked network. Therefore, if it is to be cured, it needs to have sufficient moisture in contact with it. During the curing process, the room temperature needs to be stably controlled. The temperature of 20-40°C is applied to the cloth inside the thermostat 9 to achieve rapid curing of the colloid. A thermostat 2 is provided on the side of the connecting plate 7 close to the ground. By increasing the number of thermostats, it is ensured that the cloth is always at the hottest temperature after the glue is applied. The appropriate curing temperature ensures the curing quality, and since the distance between the thermostatic tube 1 9 and the thermostatic tube 2 and the fabric is short, the temperature flowing out of the thermostatic tube 1 9 and the thermostatic tube 2 will flow between the fabric connecting plate 7, thereby ensuring the uniform temperature of the entire area. In winter, the overall room temperature will be lower than 20-40°C. Therefore, the setting of the thermostatic tube 1 9 and the thermostatic tube 2 ensures that the temperature in contact with the fabric is always at the most suitable temperature, avoiding the situation where the curing reaction is reduced due to the decrease in room temperature, resulting in incomplete curing. The side of the fabric away from the lower glue roller 1 5 is fixedly connected to a support plate 12 for supporting the fabric. The support plate 12 provides support for the fabric coating process, avoiding the fabric from being deformed by the pressure applied to it by the glue roller 1 3 and the glue roller 2 4, thereby ensuring the stable coating of the glue on the fabric.

[0023] like Figure 3 、 Figure 4 and Figure 5As shown, a receiving groove 23 is provided in the support plate 12, and a temperature control component is provided in the receiving groove 23. The temperature control component includes a humidity control plate 24 fixedly connected to the inner wall of the receiving groove 23 and a temperature insulation plate 25 slidably connected in the height direction of the receiving groove 23. The humidity control plate 24 is fixedly connected to the side of the receiving groove 23 away from the cloth. The humidity control plate 24 is composed of a plurality of humidifying tubes. The water is broken into tiny particles by an ultrasonic industrial humidifier and sprayed into the receiving groove 23 through the humidifying tubes, so as to increase the air humidity in the receiving groove 23. A plurality of micropores for humid air to flow out are provided on the side of the support plate 12 close to the cloth. By reducing the diameter of the micropores, the moisture in the humid air is reduced from directly contacting the cloth through the micropores. Since the cross-sectional area of ​​the cloth is smaller than the cross-sectional area of ​​the support plate 12, and the plurality of micropores are provided on both sides of the width direction of the support plate 12 and the part that does not contact the cloth, the humidity of the air in contact with the cloth can be increased, so that the relative humidity of the air is maintained at 40%-7 0%, in order to accelerate the curing speed of the glue, a rotating shaft 26 is rotatably connected to the inner top surface of the receiving groove 23, and the thermal insulation sheet 25 is wound on the rotating shaft 26, and a slide groove is provided on the two inner side walls along the height direction of the receiving groove 23, and a slider slidably connected to the side wall of the thermal insulation sheet 25 is fixedly connected to the side wall of the thermal insulation sheet 25. The vertical sliding of the thermal insulation sheet 25 is ensured by the arrangement of the slide groove and the slider and will not deviate during the sliding process. A plurality of through grooves are provided on the thermal insulation sheet 25, and the width of the through grooves is less than the distance between adjacent through grooves. When the cloth to be coated with glue is thinner, the thermal insulation sheet 25 will be lowered to between the humidity regulating plate 1 24 and the plurality of micropores. Due to the presence of the through grooves, a small amount of moisture can still pass through the micropores and contact the cloth, thereby ensuring that no matter how thick the cloth is, there is always an appropriate amount of moisture in contact with the glue, and the humidity regulating plate 1 24 will always generate moisture that can pass through the micropores to react with the glue, thereby ensuring the firmness of the curing of the glue and the coating quality.

[0024] like Figure 3 、 Figure 4 、 Figure 5 and Figure 8As shown, a clamping plate for clamping the cloth is provided on the top surface of the support plate 12, and the clamping plate includes a plate 19 fixedly connected to the top surface of the support plate 12 and a plate 20 slidably connected to the top surface of the support plate 12. The cloth passes between the plate 19 and the plate 20. The plate 19 and the plate 20 are fixedly connected by an elastic member 21. The elastic member 21 is configured as a spring. The configuration of the elastic member 21 ensures that there is always pressure between the plate 19 and the plate 20 to keep the two close to each other. When the elastic member 21 is at a normal length, the thickness of the cloth passing between the plate 19 and the plate 20 is relatively thin. When the cloth passing between the plate 19 and the plate 20 is relatively thick, since the plate 19 cannot move, Therefore, the cloth will exert a thrust on plate 2 20 to move it away from plate 1 19, and keep the elastic member 21 in a stretched state. The side of the unwinding roller 2 close to plate 1 19 is fixedly connected to a laser emitter 22, and the end of the unwinding roller 2 away from plate 19 is fixedly connected to a laser receiver. Plate 2 20 is slidably connected to the emission path of the laser emitter 22, and the rotating shaft 26 wrapped around the thermal insulation sheet 25 is driven by motor 1. The start of motor 1 is driven by the receiving end 1 connected to the laser receiver by Bluetooth. When the cloth passing between plate 1 19 and plate 2 20 is thin, plate 2 20 will not move away from plate 19. At this time, the light emitted by the laser emitter 22 can be received by the laser receiver. When the laser receiver can receive the light, the receiving end rotates the motor to lower the insulation plate, so that the water vapor inside the receiving tank 23 cannot enter the air through the micropores, and the glue on the cloth is solidified only through the thermostat tube 1 9 and the thermostat tube 2. Since the cloth is thin, the cloth can be quickly solidified by the low-temperature gas generated by the thermostat tube 1 9 and the thermostat tube 2 during movement. If the moisture content in the air is increased, the surface of the glue will solidify too quickly while the inside will not be completely solidified. If the cloth passing between the plate 1 19 and the plate 2 20 is thick, the plate 2 20 will be pushed by the cloth and move away from the plate 1 19. At this time, the plate 19 is located at the laser emission point. Between the emitter 22 and the laser receiver, the light emitted by the laser emitter 22 will be blocked by the plate 20. When the laser receiver cannot receive the light, the receiving end receives the signal and reverses the motor, so that the thermal insulation sheet 25 is rewound on the rotating shaft 26. At this time, the humid air in the receiving groove 23 will enter the air through the micropores to increase the humidity of the air in contact with the fabric, thereby increasing the moisture in contact with the fabric and allowing the moisture to better enter the glue layer, ensuring the complete solidification of the deep glue. At this time, the temperature of the contact part of the support plate 12 with the fabric is still low, and the low temperature can be transferred to the fabric at the same time, so that the low temperature is transferred to the depth of the glue layer, ensuring the stable solidification of the glue.

[0025] like Figure 1 、 Figure 3 、 Figure 7 and Figure 8As shown, a winding roller 10 is provided on one side of the glue coating roller 2 4, and the winding roller 10 is driven to rotate by the motor 2, so that the cloth is wound on the winding roller 10, and the winding roller 10 will apply tension to the cloth during the rotation, so that the unwinding roller 2 rotates to realize the lowering of the cloth, and the winding roller 10 is placed on the ground. When the vertical cloth passes through the glue coating roller 2 4, it will move in a direction horizontal to the ground under the drive of the winding roller 10. A refrigeration box 11 horizontal to the ground is provided between the glue coating roller 2 4 and the winding roller 10. When the cloth passes through the refrigeration box 11, the side of the cloth that forms glue faces the ground. The inner bottom surface of the refrigeration box 11 is provided with a temperature regulating plate 2, and the inner top surface of the refrigeration box 11 is provided with a plurality of water mist pipes, and the water is broken into tiny particles by an ultrasonic industrial humidifier The particles are sprayed into the refrigeration box 11 through the water mist pipe. The outer top surface of the refrigeration box 11 is rotatably connected to a fixed roller 1 and a fixed roller 2 at both ends along its length direction. A blocking plate 19 is wound on the fixed roller 1, and a pull rope 2 is fixedly connected to the fixed roller 2 on the side of the blocking plate 19 away from the fixed roller 1. The outer bottom surface of the refrigeration box 11 is rotatably connected to a fixed roller 3 and a fixed roller 4 at both ends along its length direction. A blocking plate 20 is wound on the fixed roller 3, and a side of the blocking plate 20 away from the fixed roller 3 is wound on the fixed roller 4. When the cloth enters the refrigeration box 11, the low-temperature gas generated by the temperature regulating plate 2 will quickly solidify the glue on the cloth, and the humid air generated by the water mist pipe will also diffuse in the refrigeration box 11 and contact the cloth, thereby achieving glue solidification. The glue liquid is solidified. Since the viscosity of the glue liquid coated by the glue coating roller 2 4 is low, the temperature of the temperature regulating plate 2 and the amount of humid air sprayed from the water mist pipe are reduced. While ensuring the stable solidification of the glue liquid, it is avoided that the temperature is too low, which greatly delays the moisture penetration and chemical reaction, resulting in a long curing time or even incomplete curing. Several fixed rollers are driven to rotate by motor 4. The rotation of motor 4 is controlled by receiving end 2, and receiving end 2 is also connected to the laser receiver by Bluetooth. When the cloth entering the refrigeration box 11 is thin, the laser receiver receives the light, thereby driving several fixed rollers to rotate, so that the blocking plate 19 and the blocking plate 20 move towards the direction close to the fixed roller 2 and the fixed roller 4, so that the two can cover the temperature regulating plate 2 and the water mist pipe, through the blocking plate 19 And the blocking plate 20 is used to prevent the low-temperature gas and moisture from directly contacting the cloth. The setting of the refrigeration box 11 can retain the low temperature and moisture inside it and contact the cloth. Since the density of moisture is relatively low, the moisture inside the refrigeration box 11 will be deposited below the refrigeration box 11, thereby ensuring stable contact with the glue and solidifying it. The two ends of the refrigeration box 11 in the length direction are open, and the diameter of the opening is greater than the thickness of the cloth. Therefore, while ensuring the transmission of the cloth, a small amount of moisture and low temperature in the refrigeration box 11 can overflow into the air, so that there is some moisture that contacts the cloth in advance between the end of the refrigeration box 11 close to the support plate 12 and the glue coating roller 2 4, which accelerates the curing efficiency of the glue on the cloth, and finally the cloth after the glue is solidified is wound on the winding roller 10.

[0026] Working principle: The cloth to be coated with glue is wound on the unwinding roller 2, and the cloth is moved downward in a direction perpendicular to the ground. During the downward movement, the cloth will first contact the glue roller 3. Since the glue dripping tube 13 can apply the glue inside the lower glue roller 5 to the glue roller 3, it is ensured that there is always glue on the glue roller 3 that can be coated on the cloth. During the downward transmission of the cloth, the scraper 8 will scrape the glue on the surface of the cloth flat, and then use the temperature regulating tube 9 and the temperature regulating tube 9 to adjust the temperature. Tube 2 and the moisture in the air entering from the micropores realize the solidification of the cloth. In this process, the glue dripping from the glue roller 3 will pass through the receiving box 14 and the connecting plate 7 into the lower glue roller 2 6. Since there is a diluent in the lower glue roller 2 6, the viscosity of the glue dripping from the lower glue roller 2 6 onto the glue roller 2 4 is less than the viscosity of the glue on the glue roller 1 3. When the cloth completes the second glue coating, it will pass through the refrigeration box 11 to realize the solidification of the glue on the cloth, and finally the cloth is wound up.
