Description

Technical Field

[0002] A coating machine is a device used to apply glue, coating or ink with specific functions on a roll substrate. It is widely used in packaging, textiles, footwear, papermaking, printing, electronics and other fields. Pressure-sensitive adhesive coating is a process of evenly coating pressure-sensitive adhesive on a substrate. It is widely used in the production of pressure-sensitive adhesive tapes, labels, protective films and other products. The pressure-sensitive adhesive coating machine is a key equipment to achieve this process. It improves production efficiency, product quality and expands application areas through technical features such as automatic control system, multi-functional coating head, high-efficiency drying system and adjustable coating pressure.

[0003] The pressure-sensitive adhesive coating process uses the special properties of pressure-sensitive adhesive to coat it on the surface of the substrate and achieve adhesion between the adhesive layer and the substrate by applying pressure. The pressure-sensitive adhesive has high viscosity and will produce adhesion when it comes into contact with the substrate, but it will not destroy the surface structure of the substrate. The coated adhesive is dried to solidify the adhesive to form an adhesive layer. The finished product is then rolled up and sorted.

[0037] Based on the above structure, preferably, the pressure-sensitive adhesive is also provided with a heating mechanism, and the heating mechanism is used to transport the heated pressure-sensitive adhesive to the temperature control box 52. The temperature control box 52 is used to keep warm and appropriately adjust the temperature.

In order to control the adjustment range, a temperature sensor is preferably provided in the temperature control box 52. When the temperature in the temperature control box 52 needs to be increased, the current of the electric heating wire is correspondingly increased; when the power pump 56 extracts the pressure-sensitive adhesive, the pressure-sensitive adhesive passes through the detection channel 54, driving the paddle 542 to drive the rotating rod 541 to rotate. The fluidity of the pressure-sensitive adhesive can be judged based on the rotation amplitude of the counting slot 543 detected by the visual detection unit, which can be used as a basis for judging the quality of the glue coating.

[0039] It should be noted that when the fluidity of the pressure-sensitive adhesive is insufficient, the pressure-sensitive adhesive can be stirred by driving the rotating rod 541 to rotate and improve the fluidity and uniformity. That is, the electromagnetic block 548 is energized to adsorb the top of the rotating rod 541, so that the rotating motor 546 can drive the rotating rod 541 to rotate. In order to avoid affecting other structures, the electromagnetic block 548 is only provided with an adsorption surface that can generate magnetic force at the bottom position. Conversely, the top of the rotating rod 541 is correspondingly provided with an iron material for cooperating with the adsorption.

[0040] The temperature control box 52 is provided with a double-layer structure, wherein the upper layer is a pressure-sensitive adhesive containing layer 522, and the lower layer is an air box 523. The air box 523 is externally connected with an input device and an output device. The input device is used to transport external gas into the air box 523 for heating, and the output device is used to transport the heated gas to the processing mechanism. The input device and the output device are devices such as air pumps.

[0041] One end of the adjustment frame 51 is hinged on the frame 1, and the other end is connected to a driving cylinder, which is fixed on the frame 1. The distance between the adjustment frame 51 and the coating wheel 12 can be adjusted by the telescopic movement of the driving end of the driving cylinder, so that the temperature control box 52 can be close to the front substrate 3 to avoid leakage of the upper side pressure-sensitive adhesive.

[0042] The scraper module 53 is composed of a scraper 531 and a telescopic cylinder 532, wherein the scraper 531 is fixed to the driving end of the telescopic cylinder 532, the scraper 531 is arranged with a certain curvature in cooperation with the coating wheel 12, and the telescopic cylinder 532 is used to adjust the distance between the scraper 531 and the coating wheel 12. In actual operation, the front substrate 3 is evenly coated by the scraper 531 after avoiding adhesion of the pressure-sensitive adhesive.

[0043] The pressure wheel 13 includes a fixed wheel 131, a movable wheel 132 and two adjusting cylinders 133, wherein both ends of the movable wheel 132 are respectively connected and fixed to the driving ends of the adjusting cylinders 133, the fixed wheel 131 and the movable wheel 132 are at the same horizontal height and are equal in size, and the adjusting cylinders 133 are used to drive the movable wheel 132 to move so as to adjust the distance between the fixed wheel 131 and the movable wheel 132.

[0045] The front substrate processing assembly 6 includes a processing box 61 and a nozzle assembly 62, wherein the nozzle assembly 62 rotates in the processing box 61, and openings are provided on both sides of the processing box 61 for conveying the front substrate 3. A plurality of fins 611 are fixed on the upper side of the inner wall of the processing box 61, and the fins 611 are made of a material with good heat absorption performance. The nozzle assembly 62 is provided with nozzles corresponding to the spacing of the fins 611, and one end of the nozzle assembly 62 is connected to the gas box 523, and the other end of the nozzle assembly 62 is provided with an adjustment module 63, and the adjustment module 63 is used to adjust the injection angle of the nozzle assembly 62. The processing box 61 is externally connected to an exhaust device for extracting gas in the processing box 61. It should be supplemented that: the adjustment module 63 adopts but is not limited to a motor gear driven structure, and the front substrate 3 passes through the lower side of the nozzle assembly 62, and its upper side surface is the glue coating surface, i.e., the surface that needs to be cleaned.

[0046] In actual operation, the nozzle assembly 62 is used to spray high-temperature airflow to the adhesive coating surface of the front substrate 3, thereby removing surface impurities and preheating the front substrate 3 to improve the coating quality of the pressure-sensitive adhesive; the fins 611 are used to form several airflow channels to guide the flow of air, and at the same time can absorb the heat of the airflow, thereby achieving a certain thermal insulation effect in the processing box 61.

[0047] Furthermore, a slide plate 64 is slidably provided in the processing box 61 , a detection block 65 is fixed to the inner wall of the processing box 61 , a tension detection unit is laid on the detection block 65 , and a spring 66 is connected between the detection block 65 and the slide plate 64 .

[0048] It should be noted that the slide plate 64 is used to reduce the airflow space inside the processing box 61 according to the width of the front substrate 3 passing through, and the detection block 65 is used to detect whether the airflow inside the processing box 61 is too fast to cause excessive internal pressure, and adjust the nozzle assembly 62 according to the detection result.

[0049] The post-substrate processing component 7 includes a scraper 71 and a negative pressure chamber 72, wherein the scraper 71 is arranged on the cleaning wheel 14, and the negative pressure chamber 72 is fixed on the upper side of the scraper 71. The scraper 71 is used to scrape off impurities on the surface of the cleaning wheel 14, and the negative pressure chamber 72 is externally connected to an exhaust device to remove impurities accumulated on the scraper 71.

[0050] Furthermore, when used for preheating the surface of the rear substrate 4, the cleaning wheel 14 is provided with a cavity for introducing a high-temperature airflow.

[0051] A plurality of heating lamps 81 are provided on the upper and lower sides of the drying box 8 for drying.

[0052] The specific implementation methods are as follows:

[0053] Step 1: The substrate is unrolled, and the front substrate 3 and the rear substrate 4 are put into the roller conveying mechanism;

[0054] Step 2: pretreatment of the substrate, the processing mechanism cleans the surface of the front substrate 3 and the rear substrate 4 from impurities and preheats them;

[0055] Step 3: Pretreatment of the pressure-sensitive adhesive. The pressure-sensitive adhesive is heated to a suitable temperature by a heating mechanism and then input into a temperature control box 52 for heat preservation. The detection cylinder 544 extracts the pressure-sensitive adhesive in the temperature control box 52. The pressure-sensitive adhesive fluidity is judged to be in the best coating state according to the rotation amplitude of the counting slot 543. The temperature of the temperature control box 52 is adjusted or the rotating rod 541 is driven to automatically stir to improve the uniformity of the pressure-sensitive adhesive.

[0056] Step 4: Glue coating. The front substrate 3 passes through the coating wheel 12. The power pump 56 draws the pressure-sensitive adhesive to the upper space of the temperature control box 52. The pressure-sensitive adhesive is coated on the surface of the front substrate 3 and evenly coated by the scraper module 53.

[0057] Step 5: Pressing: the front substrate 3 and the rear substrate 4 are combined at the pressing wheel 13 and pressed and outputted by the pressing wheel 13;

[0058] Step 6: Drying and rolling up. The front substrate 3 and the rear substrate 4 after lamination are dried by a processing mechanism and then rolled up for storage.

[0059] Specifically, the viscosity and viscoelasticity of pressure-sensitive adhesives are important physical properties that affect the ease of coating. The viscosity of pressure-sensitive adhesives is greatly affected by temperature and shear rate. The higher the temperature and shear rate, the lower the viscosity and the better the fluidity. At a fixed temperature, when most polymer molecular chains are stretched and oriented, the viscosity value will stabilize. Therefore, the temperature setting during coating needs to take into account the viscosity and viscoelasticity of the pressure-sensitive adhesive to ensure the uniformity of coating and the quality of the adhesive layer.

[0060] In step three, it is set to record that the pressure-sensitive adhesive is in an ideal flow state (the temperature of the pressure-sensitive adhesive is in an ideal state range), the power pump 56 draws a certain amount of pressure-sensitive adhesive through the detection channel 54, the pressure-sensitive adhesive drives the rotating rod 541 to rotate, and the counting slot 543 at the upper end of the rotating rod 541 rotates, and the visual inspection unit records the rotation speed as a comparison range, and the viscosity of the pressure-sensitive adhesive is adjusted by adjusting the temperature in the temperature control box 52, and the uniformity of the pressure-sensitive adhesive is improved by the automatic stirring of the rotating rod 541, thereby improving the coating quality.

[0061] In step 2, the temperature control box 52, the front substrate processing component 6 and the rear substrate processing component 7 can form a heat recycling system, wherein the temperature control box 52 mainly provides the temperature required by the pressure-sensitive adhesive, and the heat generated can be used to heat the airflow input into the air box 523. The heated airflow is respectively transported to the front substrate processing component 6 and the cleaning wheel 14 for removing impurities from the surface of the front substrate 3 and preheating the rear substrate 4. The airflow output from the cleaning wheel 14 will pass into the negative pressure chamber 72 to remove impurities accumulated on the scraper 71. Finally, the front substrate processing component 6 and the negative pressure chamber 72 output the airflow that has lost heat and is entrained with impurities, which is re-input into the temperature control box 52 for heating after passing through a separately arranged filter box, forming a heat utilization cycle.
