In accordance with the present invention, the use of organic solvents is avoided during the preparation of the ink transfer medium 10 such that the residual organic solvent content of the ink transfer medium 10 is less than or equal to 0.1 PPM.

As shown in fig. 11, the present embodiment provides a thickness measuring apparatus 100 for an ink transfer medium, and the thickness measuring apparatus 100 may include an unwinding roller 101, a first roller 102, a measuring roller 103, a detector 104, a second roller 105, a winding roller 106, and a receiver (not shown). The unwinding roller 101, the first roller 102, the measuring roller 103, the detector 104, the second roller 105 and the winding roller 106 are arranged in sequence. The unwinding roller 101 is used to unwind the ink transfer medium, and the first roller 101 and the second roller 105 are used to tension the ink transfer medium, whereby the ink transfer medium can be completely attached to the surface of the metering roller 103. Take-up roll 106 is used to collect the ink transfer medium. The detector 104 is used for emitting light to the measuring roller 103, the light is reflected by the measuring roller 103 to form reflected light, and the receiver is used for receiving the reflected light and recording the time of receiving the reflected light. The time of the light reaching the measuring roller 103 is equal to the time of the reflected light reaching the receiver, so that a half of the time of the reflected light received by the receiver can be defined as the time of the light reaching the measuring roller 103.

As shown in fig. 11, in the present embodiment, the measuring roller 103 may be located between the first roller 102 and the second roller 105, and the height of the measuring roller 103 is greater than that of the first roller 102 and the second roller 105, so that the ink transfer medium can be completely attached to the measuring roller 103.

s2: emitting light rays to the measuring roller wheel through the detector, wherein the light rays form reflected light rays through the measuring roller wheel;

s3: receiving the reflected light through the receiver, and recording the time of receiving the reflected light so as to calculate the distance from the detector to the measuring roller;

s4: disposing an ink transfer medium on the thickness measurement device to calculate a distance of the probe to the ink transfer medium;

s5: the thickness of the ink transfer medium is calculated.

As shown in fig. 11 and 13, in steps S1-S3, a thickness measuring device 100 is provided, and then a light beam is emitted to the measuring roller 103 through the detector 104, for example, the light beam emitted by the detector 104 is a first light beam L1, and the first light beam L1 forms a first reflected light beam after being reflected by the measuring roller 103. The first reflected light is received by the receiver, and the receiver simultaneously records the time of receiving the first reflected light, for example, the time of receiving the first reflected light by the receiver is defined as a first time t1, so that the distance between the detector 104 and the measuring roller 103 can be calculated according to the first time t 1. The distance between the detector 104 and the measuring roller 103 may be equal to c x t1/2, where c represents the speed of light and t1 represents the first time.

As shown in fig. 11 and 14 to 15, in steps S4 to S5, the ink transfer medium 10 is released by the unwinding roller 101 while the ink transfer medium 10 is tensioned by the first roller 102 and the second roller 105, so that the ink transfer medium 10 can be completely attached to the measuring roller 103. Then, a second light L2 is emitted to the measuring roller 103 by the detector 104, the second light L2 forms a second reflected light after being reflected by the ink transfer medium 10, the second reflected light is received by the receiver, and the time of receiving the second reflected light is recorded, for example, the time of receiving the second reflected light is defined as a second time t2, so that the distance between the detector 104 and the ink transfer medium 10 can be calculated, the distance between the detector 104 and the ink transfer medium 10 is equal to c × t2/2, wherein c represents the light speed, and t2 represents the second time. Since the ink transfer medium 10 has a certain thickness, the first time t1 is greater than the second time t2, and thus the thickness of the ink transfer medium 10 can be calculated. The thickness of the ink transfer medium 10 may be equal to (t1-t 2). times.c/2. The present embodiment uses light to irradiate the ink transfer medium 10 in real time, so that the thickness measuring apparatus 100 can always measure the thickness of the ink transfer medium 10 while the ink transfer medium 10 is continuously moving. If the thickness measuring device 100 detects that the thickness of a section of the ink transfer media 10 is not uniform, the ink transfer media 10 can also be processed and then the processed ink transfer media 10 can be applied to a printing process, thereby improving the quality of the printed product.

As shown in fig. 15, in the present embodiment, the length of the second light L2 may be equal to the width of the ink transfer medium 10, so that the second light L2 can completely measure the thickness of the ink transfer medium 10. The width of the second light L2 may be 1 cm.

As shown in fig. 11, in this embodiment, the thickness measuring apparatus 100 can measure the thickness of the ink transfer medium on line in real time, and the unevenness of the ink transfer medium can be controlled within 0.02mm by the thickness measuring apparatus 100, so that the quality of the printed matter can be greatly improved.

In summary, the present invention provides an ink transfer medium thickness measuring apparatus and a measuring method thereof, wherein before measuring the thickness of the ink transfer medium, a detector is calibrated, light is emitted to a measuring roller through the detector, reflected light is formed after the light is reflected by the measuring roller, the reflected light is received through a receiver, and the time of receiving the reflected light is recorded, so that the distance from the detector to the measuring roller can be calculated. The distance from the detector to the measuring roller may be equal to half the product of the speed of light and the reflected light. When the ink transfer medium is placed on the thickness measuring device, the ink transfer medium is tensioned through the first roller and the second roller, then light is emitted to the ink transfer medium through the detector, the light is reflected by the ink transfer medium to form reflected light, the reflected light is received by the detector, and the time of receiving the reflected light is recorded; then calculating the distance from the detector to the ink transfer medium; so that the thickness of the ink transfer medium can be calculated; the thickness of the ink transfer medium is equal to the difference between the distance from the probe to the measuring roller and the distance from the probe to the ink transfer medium. The thickness measuring device of the present invention can measure the thickness of the ink transfer medium in real time. If the uniformity of the thickness of the ink transfer media is poor, the ink transfer media can also be processed and then applied to a printing process, thereby improving the quality of the printed matter.

As shown in fig. 16, this embodiment also proposes a calendaring apparatus 200, which calendaring apparatus 200 can be used to manufacture ink transfer media. The calendaring apparatus 200 may include a first unwinding roller 201, and the first unwinding roller 201 is provided with a first material layer, that is, the first unwinding roller 201 may transmit a first material layer to the first calendaring roller, and the first material layer is, for example, a first substrate layer. A first calendering group is disposed at the rear end of the first unwinding roll 201, and the first calendering roll may include a first calendering roll 202 and a second calendering roll 203 of the opposing apparatus. The first unwind roll 203 is used to transfer the first layer of material to the first calender group, i.e., into the gap between the first calender roll 202 and the second calender roll 203. The diameters of the first reduction roll 201 and the second reduction roll 202 in the present embodiment may be the same, and the diameters of the first reduction roll 202 and the second reduction roll 203 may be 420 mm. Note that the arrow in the middle of the first unwinding roll 201 and the first calendering group indicates the moving direction of the first material layer.

As shown in fig. 16, in the present embodiment, after the first material layer passes through the first calendering roll 201 and the second calendering roll 202, the first material layer extends and then passes through the first tension roll 204 into the second calendering set. The first tension roller 204 can ensure that the first material layer enters the second calendering group in a linear manner, namely the first material layer enters the second calendering group after clinging to the third calendering roller 205, and the first material layer clings to the third calendering roller 205, so that air bubbles between the first material layer and the third calendering roller 205 can be reduced, and the product yield can be improved.

As shown in fig. 16, in the present embodiment, the second calendering group can include a third calendering roll 205 and a fourth calendering roll 206 that are oppositely disposed, with the third calendering roll 205 disposed on the fourth calendering roll 206. After passing through the third calender roll 205, the first material layer enters the gap between the third calender roll 205 and the fourth calender roll 206, and the first material layer is calendered again. Note that the gap between the first reduction roll 202 and the second reduction roll 203 is larger than the gap between the third reduction roll 205 and the fourth reduction roll 206, whereby the first material layer can be rolled again. In the present embodiment, the diameters of the third reduction roll 205 and the fourth reduction roll 206 may be the same, and the diameters of the third reduction roll 205 and the fourth reduction roll 206 may be 420 mm. A second unwinding roller 207 is further arranged at the rear end of the second rolling group, a second tension roller 208 is further arranged between the second unwinding roller 207 and the second rolling group, and the height of the second tension roller 208 is lower than that of the second unwinding roller 207. A second material layer is arranged on the second unwinding roll 207, and the second material layer can enter between the third calendering roll 205 and the fourth calendering roll 206 through a second tension roll 208. The second material layer can be ensured to enter the space between the third calendering roll 205 and the fourth calendering roll 206 in a straight line by providing a second tension roll 208. Since the gap between the third calendering roll 205 and the fourth calendering roll 206 is smaller than the gap between the first calendering roll 205 and the second calendering roll 206, the first material layer can be laminated on the second material layer or the second material layer can be laminated on the first material layer, and the second material layer can be a face glue layer or other material layer. Release layers are provided on each of the first calender roll 202, the second calender roll 203, the third calender roll 204 and the fourth calender roll 205, and thus the first material layer can be prevented from adhering between the first calender roll 202 and the second calender roll 203 or the second material layer can be prevented from adhering between the third calender roll 205 and the fourth calender roll 206. The arrow between the second unwinding roller 207 and the second tension roller 208 indicates the direction of movement of the second material layer. In the present example, the calendering rates of the first calendering group and the second calendering group are, for example, 5 to 15m/h, for example 10 m/h.

As shown in fig. 16, in the present embodiment, a wind-up roll 210 is further provided at the front end of the second rolling group, and a third tension roll 209 is further provided between the wind-up roll 210 and the second rolling group. After the first material layer and the second material layer pass through the third calender roll 205 and the fourth calender roll 206, a composite layer is formed. The composite layer passes through a third tension roller 209 and enters a wind-up roller 210, so that the composite layer is wound up. In this embodiment, the third tension roller 209 can ensure that the composite layer is formed into a line and enters the wind-up roller 210, so as to ensure that the winding is neat and prevent the material from shaking.

As shown in fig. 16, a thickness measuring device 211 is also provided directly below the third tension roller 209, and the thickness measuring device 211 is located directly below the contact surface between the third tension roller 209 and the composite layer. The thickness measuring apparatus 211 can be used to measure the thickness of the composite layer on-line. The thickness measuring apparatus 211 can measure the thickness of the composite layer by referring to the above description, and the embodiment is not illustrated.

As shown in fig. 17, this embodiment also proposes a manufacturing system for an ink transfer medium, including a calendaring apparatus and a vulcanizing apparatus 500. The structure of the rolling device 200 can refer to the above description. Of course, in some embodiments, the manufacturing system may include two curing apparatuses 500.

In summary, the present invention provides a rolling apparatus for an ink transfer medium and a manufacturing system thereof, in which a first unwinding roller is disposed at a front end of a first rolling group, a first tension roller is disposed at a rear end of the first unwinding roller, a second rolling group is disposed at a rear end of the first tension roller, a second unwinding roller is disposed at a rear end of the second rolling group, and a second unwinding roller is disposed between the second unwinding roller and the second rolling group. According to the utility model, the first material layer is conveyed into the first rolling group through the first unwinding roller, the second material layer is conveyed into the second rolling group through the second unwinding roller, and then when the rolling equipment works, the second material layer is pressed on the first material layer through the second rolling group. According to the utility model, the first tension roller and the second tension roller can ensure that the first material layer and the second material layer enter the second calendering roller, the rolling is tidy, and the placed material shakes. According to the utility model, the thickness measuring equipment is arranged right below the third tension roller, so that the thickness of the composite layer can be measured in time.

As shown in fig. 18, this embodiment further provides a glue filter 300, which is required to filter the configured glue when manufacturing the ink transfer medium 10, so as to filter out larger particles, thereby meeting the glue requirement of manufacturing the ink transfer medium 10, and thus ensuring the quality stability of the ink transfer medium 10.

As shown in fig. 18, in this embodiment, the glue filter 300 may include a roller 301, and the roller 301 includes a glue 302 therein. A plunger 303 is arranged on the top of the roller 301, the plunger 303 is connected with an oil cylinder 304, and the oil cylinder 304 drives the plunger 303 to move. When cylinder 304 moves plunger 303 downward, plunger 303 may be caused to squeeze cement 302, thereby causing cement 302 to move downward. Since a screen 305 is provided on the bottom of the drum 301, the mucilage 302 pressed by the plunger 303 can flow out of the screen 305 and into the pulp barrel 306. In this embodiment, the filter screen 305 is, for example, a 50-400 mesh steel mesh. In this embodiment, the filter screen 305 may be fixed at the bottom of the drum 301 by bolts, so that the filter screen 305 may be detached after the glue filter 300 is used for a period of time, thereby facilitating the cleaning of the filter screen 305.

As shown in fig. 18, in the present embodiment, a bracket 307 is further provided on the drum 301, and the bracket 307 may surround the drum 301. The bracket 307 is detachably fixed on the roller 301, and the pulp containing barrel 306 can be positioned above the ground due to the action of the bracket 307, so that universal wheels can be arranged at the bottom of the pulp containing barrel 306. Therefore, after the mortar containing barrel 306 is filled with the mortar, the mortar containing barrel 306 can be moved outwards conveniently.

As shown in fig. 19, in the present embodiment, the drum 301 may include a cover 3011 and a paddle 3012, for example, a region above a dotted line is defined as the cover 3011, and a region below the dotted line is defined as the paddle 3012. Opening cover 3011 allows placement of the cement into cylinder 3012, then plunger 303 into drum 301, and then locking cover 3011 and cylinder 3012. In this embodiment, the plunger 303 may pass through the cover 3011 to connect to the cylinder 304. The temperature of cement 302 increases as the bottom plate of plunger 303 presses cement 302 downward, but in this embodiment, the temperature of cement 302 can be controlled below 70 ℃, so that the temperature can be lower than the vulcanization temperature of cement 302, and cement 302 is prevented from being vulcanized. It should be noted that the bottom plate of the plunger 303 is also in contact with the inner wall of the drum 301, so that the paste 302 can be fully pressed.

As shown in fig. 18, in some embodiments, a pressure regulator may be further provided, by which the pressure of plunger 303 pressing cement 301 may be adjusted, thereby increasing the filtration rate of cement 301. In some embodiments, the drum 301 may be driven by a motor to rotate, so as to increase the filtering rate of the cement 301.

As shown in fig. 18, in the present embodiment, by pressing the paste 302 using the plunger 303, the paste 302 can be filtered out of the screen 305, and therefore, small particles of the paste 305 can be obtained, so that the quality of the ink transfer medium 10 can be improved. Meanwhile, in the process of extruding the paste 302, the heat generated by the plunger 303 and the paste 302 is small, so that the temperature of the paste 302 is low, that is, the paste 302 is not vulcanized, and the quality of the ink transfer medium 10 can be improved.

As shown in fig. 20, the present embodiment further provides a polishing apparatus 400 for an ink transfer medium, wherein the polishing apparatus 400 can polish the ink transfer medium 10, so as to obtain the ink transfer medium 10 with good thickness flatness and uniform surface roughness.

As shown in fig. 20, the present embodiment provides a polishing apparatus 400 for an ink transfer medium, and the polishing apparatus 400 may include a unwinding roller 101, a polishing area, and a winding roller 106. The unwinding roller 101 is used for placing the ink transfer medium 10, and after the ink transfer medium 10 passes through the polishing area, the flatness and thickness of the ink transfer medium 10 can be changed, and meanwhile, the surface roughness of the ink transfer medium 10 is also changed. After the ink transfer media 10 has been sanded, the ink transfer media 10 may be collected by a take-up roll 106.

As shown in fig. 20, in this embodiment, the unwinding roller 101 may be disposed on the clutch 1011, and the unwinding speed of the unwinding roller 101 may be controlled by the clutch 1011, so as to control the pressure between the ink transfer medium 10 and the polishing roller 401. The sanding zone may include a plurality of sanding rollers 401 and a plurality of guide rollers 404. When the ink transfer medium 10 enters the polishing area, the ink transfer medium first contacts the polishing rollers 401 and sequentially passes through the polishing rollers 401, for example, the upper surface and the lower surface of the ink transfer medium 10 respectively contact different polishing rollers 401, so that both the upper surface and the lower surface of the ink transfer medium 10 can be polished.

As shown in fig. 20, in this embodiment, a pressure sensor 402 may be further disposed on the second sanding roller 401, and the pressure sensor 402 may be connected to the clutch 1011. When the pressure sensor 402 detects that the pressure of the ink transfer medium 10 and the pressure of the polishing roller 401 change, the anti-rolling speed can be controlled through the clutch 1011, so that the pressure of the ink transfer medium 10 and the pressure of the polishing roller 401 can be adjusted, the problems of uneven thickness, surface waviness and the like caused by uneven tension can be solved, and the surface roughness grade of a product is improved. For example, when the pressure sensor 402 detects that the pressure between the ink transfer medium 10 and the polishing roller 401 is decreased, that is, the unwinding speed is greater than the rotation speed of the polishing roller 401, the unwinding speed of the unwinding roller 101 can be reduced by the clutch 1011, so that the unwinding speed of the unwinding roller 101 is matched with the rotation speed of the polishing roller 401. When the pressure sensor 402 detects that the pressure of the ink transfer medium 10 and the pressure of the polishing roller 401 are increased, that is, the unwinding speed is lower than the rotation speed of the polishing roller 401, the unwinding speed of the unwinding roller 101 can be increased through the clutch 1011, so that the unwinding speed of the unwinding roller 101 is matched with the rotation speed of the polishing roller 401.
