Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for adhesive tape production, in particular to a coating roller used in conjunction with an adhesive tape coating machine. Background Art

[0002] In the production of tapes (such as perforated tapes used in solar panel assembly, high-temperature tapes, frame sealing tapes, etc.), glue (also called adhesive, which is dried after coating) needs to be coated on the base tape through a coating machine through related equipment to give the finished product a certain degree of bonding ability.

[0003] When the existing coating machine uses glue to coat the substrate tape, the liquid raw material in the glue tank is generally input into the coating roller of the coating machine through a glue pump, and then the glue with a certain pressure flows out from the multiple glue outlet holes on the surface of the coating roller to the substrate tape (the rear end of the coating roller of the coating machine also has a scraping mechanism and a drying mechanism, which can scrape the glue on the substrate tape flat, so that the glue is evenly coated on the substrate tape and subsequently dried). Although the existing coating rollers meet the coating needs to a certain extent, they are limited by the structure and still have the following technical problems. Specifically, when the temperature in the production area is low, the fluidity of the glue will deteriorate after entering the coating roller. In this way, the glue will not easily flow out evenly from the multiple glue outlet holes on the surface of the coating roller, which will more or less have an adverse effect on the gluing effect of the substrate. In summary, it is very necessary to provide a coating roller that can ensure the fluidity of the glue as much as possible. Utility Model Content

It also has a rotating power supply mechanism 3 and a control circuit 4; a connecting shaft 101 and a connecting pipe 102 are horizontally welded in the middle of both sides of the glue roller body 1, and the outer sides of the middle parts of the connecting shaft 101 and the connecting pipe 102 are tightly sleeved in the inner rings of the bearing seats 2 on the left and right sides, and the inside of the connecting pipe 102 is interconnected with the inside of the glue roller body 1, the motor reduction mechanism M1 and the lower ends of the two sets of bearing seats 2 are respectively installed on both sides of the glue coating station of the coating machine (not shown in the figure) by bolts, and ... The right end of the rotating shaft of the mechanism M1 and the left end of the connecting shaft 101 are welded together; a bearing 103 is tightly sealed inside the right end of the connecting pipe 102, and a sealing ring is sealed on the inner and outer rings of the left and right sides of the bearing 103 respectively (to prevent the glue entering the glue roller body 1 from escaping), and a glue inlet pipe 104 is tightly sealed in the inner ring of the bearing 103. The outer side of the upper end of the glue inlet pipe 101 is connected to the outlet pipe of the glue pump of the coating machine through a pipeline, and the upper left outer end of the glue inlet pipe 104 and the upper right side of the right end bearing seat 2 are welded together through a connecting rod 5; there are three electric heating pipes RT, and three wire seats 105 and three wire holes 105 are respectively distributed in an annular manner on the inner right end and left end of the glue roller body 1. 6. The left and right side ends of each electric heating tube RT have external threads respectively. The left and right ends of the three electric heating tubes RT are respectively screwed into the internal threads of the three wire seats 105 and the internal threads of the three wire holes 106 on the right side of the rubber coating roller through the external threads, and then the three electric heating tubes RT are sealed and installed in the rubber coating roller body 1 at an annular spacing. The left terminal of the three electric heating tubes RT is located on the left side of the outer end of the rubber coating roller body 1; the rotating power supply mechanism includes an insulating sleeve 31, a copper metal ring T, and a copper contact piece H. The inner side of the plastic sleeve 31 is tightly sleeved on the outside of the right side of the connecting shaft 101 (sealing the spacing between the left side of the connecting shaft 101 and the right side of the left end bearing seat 2), and the inner sides of the two metal rings T are tightly sleeved on the sleeve 31 at a spacing of left and right. On the outside of the left end bearing seat 2, a wire groove 107 is horizontally distributed on the upper end of the sleeve, and a wire is welded to the inner side of each of the two metal rings T. The two wires are glued in the wire groove and the upper end height is lower than the upper end height of the metal ring T. The right side of the two wires and the power input end of the left outer end of the three electric heating tubes RT are respectively connected in parallel; an insulating seat 6 is horizontally glued to the middle of the front side of the left end bearing seat 2, and the rear ends of the two contact pieces H are hot-melt welded to the upper end of the insulating seat 6 at a distance from each other; a connecting plate is horizontally welded to the upper end of the left end bearing seat 2, and the infrared temperature measurement module A2 is vertically distributed and installed on the right side of the connecting plate 7; the power module A1 and the control circuit 4 are installed in the electrical control box 8 of the coating machine.

[0017] Figure 1 、 2As shown in Figures 3 and 4, the front lower side of the contact piece H is in electrical sliding contact with the outer sides of the upper ends of the two metal rings T. The detection head of the infrared temperature measurement module A2 is directed downwardly toward the outer left side of the upper end of the glue roller body 1. The surface of the glue roller body has multiple glue outlet holes 108. The control circuit includes an adjustable resistor R2, resistors R1 and R3, a transistor Q1, and a relay J1, which are connected via circuit board wiring. One end of the adjustable resistor R2 is connected to one end of the first resistor R1 and one end of the second resistor R3. The other end of the second resistor R3 is connected to the base of the transistor Q1. The collector of the transistor Q1 is connected to the negative power input terminal of the relay J1. The other end of the adjustable resistor R2 is connected to the emitter of the transistor Q1 and the control power input terminal of the relay J1. The power input terminals 1 and 2 of the power module A1 are connected to the two poles of the AC 220V power supply via wires, respectively. The power output terminals 3 and 4 of the power module A1 are connected to the power input terminals 1 and 2 of the infrared temperature measurement module A2, the positive power input terminal of the control circuit's power input relay J1, and the emitter of the transistor Q1 via wires, respectively. The signal output terminal 3 of the infrared temperature measurement module A2 is connected to the other end of the adjustable resistor R1 at the signal input terminal of the control circuit via a wire. The normally closed contact terminal of the control circuit's power output relay J1, the positive power output terminal 3 of the power module A1, and the power input terminals of the two contact pieces T are connected via wires, respectively.

[0018] Figure 1 、 2As shown in Figures 3 and 4, after the main power switch is turned on, the motor reduction mechanism M1 and power module A1 are energized and operated. Pins 3 and 4 of power module A1 output a stable 24V DC power supply, which enters the power input terminal of the control circuit, etc. When the motor reduction mechanism M1 is energized and operated, its rotating shaft drives the glue roller body 1 to rotate clockwise. The glue pump (mature technology, not described in detail in this application) extracts the liquid raw material from the glue tank and pressurizes it into the glue inlet pipe 104. Then, it enters the glue roller body 1 through the glue inlet pipe 104 (the left side of the glue inlet pipe 104 is located inside the inner ring of the bearing 103, and the right side of the glue roller body 1 rotates along the outer ring of the bearing 103 through the connecting pipe 102, while the glue inlet pipe does not rotate). The glue under a certain pressure then flows out of the multiple glue outlet holes 108 on the surface of the glue roller body 1 onto the substrate belt (the rear end of the glue roller of the coating machine also has a glue scraping mechanism and a drying mechanism, which can scrape the glue on the substrate belt, ensuring that the glue is evenly coated on the substrate belt and subsequently dried). The DC 24V power supply enters the two contact pieces H through the power input terminal and the normally closed contact terminal of the relay J1. The two contact pieces H contact the outer sides of the two rotating metal rings T. In this way, the rotating metal rings T can effectively supply power to the three electric heating tubes RT, and the three electric heating tubes RT are energized to heat the glue in the glue roller body 1. When the glue temperature in the glue roller body 1 is lower than a certain level (for example, lower than 60°C), the detection head of the infrared temperature measurement module A2 detects it and its signal output terminal 3 pin, the output signal voltage is divided by the resistor R1 and the adjustable resistor R2, and the resistor R3 reduces the voltage and limits the current to enter the base of the transistor Q1 below 0.7V, the transistor Q1 will not be turned on, and the relay J1 will not be energized and absorbed. The control power input terminal and the normally closed contact terminal continue to be closed, and the three electric heating tubes RT continue to be energized to heat the glue in the glue coating roller body; when the glue temperature in the glue coating roller body 1 is higher than a certain temperature (for example, higher than 60°C), the detection head of the infrared temperature measurement module A2 detects it and its signal output terminal 3 pin, the output signal voltage is divided by the resistor R1 and the adjustable resistor R2, the resistor R3 reduces the voltage and limits the current to enter the base of the transistor Q1 is higher than 0.7V, the transistor Q1 will turn on the collector output low level to enter the negative power input terminal of the relay J1, the relay J1 will be energized to close its control power input terminal and the normally closed contact terminal is open, and the three electric heating tubes RT will no longer be energized to heat the glue in the glue coating roller body. Through the above, in this new application, the electric heating tube can heat the glue entering the glue coating roller body at a constant temperature under the action of the control circuit, infrared temperature measurement module, etc., and because it has the function of a rotating power supply mechanism, it can ensure that the rotating electric heating tube is effectively heated, thereby ensuring the fluidity of the glue as much as possible and improving the quality of the substrate with uniform glue coating. Figure 4In the figure, relay J1 is a DC24V relay; power module A1 is a finished product of a 220V AC to 24V DC switching power module; resistors R1 and R3 have resistance values ​​of 4.7K and 20K respectively; transistor Q1 is a 9013 NPN transistor; motor reduction mechanism M1 (220V) is an electric gear reducer with a power of 1.2KW; adjustable resistor R2 has a resistance value of 470K (the larger the resistance is, the greater the partial pressure is, so that when the temperature inside the subsequent coating roller body 1 is relatively low, the transistor Q1 will be turned on, that is, the temperature of the new type of coating roller is relatively low). The threshold is set relatively low; the smaller the resistance is adjusted to, the smaller the partial pressure is, so that when the temperature inside the subsequent coating roller body 1 is relatively high, the transistor Q1 will be turned on, that is, the temperature threshold of the new model is set relatively high); the electric heating tube RT is a finished stainless steel armored strip electric heating tube (power 800W); the infrared temperature measurement module A2 is a finished online infrared thermometer temperature sensor model SA10AS, which has two power input terminals and a signal output terminal. As the probe detects different temperatures, the signal output terminal will output a dynamically changing voltage signal of 0-5V.
