Description

Polishing equipment for printing ink transfer medium

Technical Field

The invention relates to the technical field of printing, in particular to polishing equipment for an ink transfer medium.

Background

The rubber blanket is a composite material product formed by a rubber layer and a base material, and particularly, the rubber blanket generally comprises a cloth bottom, an air cushion layer and a rubber layer on the surface. In offset lithography, ink is transferred from a printing plate to a substrate using the offset lithography.

After the blanket is manufactured, the blanket needs to be polished, so that the blanket which is relatively flat and has certain roughness is obtained. Now, the blanket is generally roughly ground and then finely ground, but the pressure between the blanket and the grinding roller during grinding may be too large or too small, thus resulting in poor flatness of the blanket.

Disclosure of Invention

In view of the defects of the prior art, the invention provides a polishing device for an ink transfer medium, which can obtain the ink transfer medium with better flatness and uniform surface roughness.

To achieve the above and other objects, the present invention provides an ink transfer medium polishing apparatus comprising:

an unwinding roller;

the polishing assembly is positioned on one side of the unwinding roller;

the polishing assembly is positioned between the unwinding roller and the winding roller;

the polishing assembly comprises a plurality of polishing rollers and a plurality of guide rollers, wherein the polishing rollers are arranged on the clutch, the polishing rollers are close to the unwinding rollers, pressure sensors are arranged on the polishing rollers, and the pressure sensors are connected with the clutch.

Further, the ink transfer medium passes through the plurality of burnishing rollers and the plurality of guided rollers in sequence.

Further, the pressure sensor is arranged on the second polishing roller and used for detecting the pressure of the printing ink transfer medium and the second polishing roller.

Further, when the pressure sensor detects that the pressure of the printing ink transfer medium and the pressure of the second polishing roller are smaller than a threshold value, the clutch reduces the unwinding speed of the unwinding roller.

Further, when the pressure sensor detects that the pressure of the printing ink transfer medium and the pressure of the second polishing roller are larger than a threshold value, the clutch improves the unwinding speed of the unwinding roller.

Further, the polishing assembly further comprises a deviation rectifier, and the deviation rectifier is arranged between the third polishing roller and the fourth polishing roller.

Further, the deviation rectifier is used for adjusting the position of the ink transfer medium.

Further, the polishing equipment further comprises an exhaust fan, and the exhaust fan is arranged on the polishing assembly.

Further, a constant torque motor is arranged on the winding roller.

Further, the polishing assembly further comprises a detector, wherein the detector is positioned on the polishing roller and is used for measuring the thickness of the ink transfer medium.

In summary, the present invention provides a polishing apparatus for an ink transfer medium, which can detect a pressure between the ink transfer medium and a polishing roller, that is, detect a pressure between the ink transfer medium and the polishing roller by a pressure sensor, and feed back the pressure value to a clutch. When the pressure value is smaller than the threshold value, the unwinding speed of the unwinding roller wheel can be reduced through the clutch, and when the pressure value is larger than the threshold value, the unwinding speed can be improved through the clutch. Therefore, the unreeling speed can be matched with the rotating speed of the polishing roller wheel, and the position of the ink transfer medium is adjusted through the deviation rectifier, so that the surface roughness of the ink transfer medium is improved, and the problems of uneven thickness, surface ripples and the like caused by uneven tension are solved.

The first fabric material within the above range is not elongated, is not broken, and is not deformed, has a good affinity with the air cushion layer 12 and the surface adhesive layer 14, and is easily adhered to and not easily detached from the air cushion layer and the surface adhesive layer, so that the first base material layer 11 based on the first fabric material can make the ink transfer medium 10 bear a radial force of 500kg or more, further, bear a radial force of 1000kg without being deformed, and has good compressibility and flexibility.

As shown in fig. 3, the first adhesive layer 112 is located between the first cloth layer 111 and the second cloth layer 113 for adhering them without glue leakage, and the interlayer adhesion between the first cloth layer 111 and the second cloth layer 113 should have an adhesive force of 1.5KN/m or more, and further 1.8KN/m or more, based on the adhesion of the first adhesive layer 112, so that the ink transfer medium 10 is prevented from being broken by a radial force during use. The first adhesive layer 112 may employ, for example, an anaerobic adhesive such as butyl acrylate and C2 to C10 alkyl esters, which are usually acrylic acids; epoxy resins, for example one-component resin adhesives, such as dicyandiamide (cyanoguanidine), or two-component systems using polyfunctional amines or polyfunctional acids as curing agents, or using cyanoacrylates; or a hot melt adhesive such as polyethylene, polyvinyl acetate, polyamide, hydrocarbon resin, resinous material, and wax, and may also be a pressure sensitive adhesive. The thickness of the first adhesive layer 112 is, for example, 0.1mm to 1mm, such as 0.13mm, 0.2mm, 0.3mm, 0.5mm, 0.7 mm.

As shown in fig. 4 and 6, the air cushion layer 12 is disposed on the first substrate layer 11, the air cushion layer 12 has a micro-porous structure and further comprises microspheres, specifically, the raw material components of the air cushion layer 12, such as the microspheres, rubber components, and additives, are vulcanized at a certain temperature and in a plurality of temperature ranges to form a foamed micro-porous structure, the micro-pores are fully closed micro-pores with diameters of, for example, 0.005-0.03mm, such as 0.01mm, 0.013mm, and have uniform and complete pores with an average porosity of 70-80%, and have compressibility of 0.10-0.18 mm, such as 0.20mm, 0.66mm, and 0.1mm, so that the micro-pores absorb printing pressure during printing without bulging the surface of the ink transfer medium 10 to cause deformation, and when the printing pressure is removed, the micro-pores are rapidly recovered, while the pressure during printing remains substantially constant, the printing speed can be up to 1.5 million prints of high speed printing, further 1.8 million prints or more, for example 2 million prints, based on the characteristics of the air bearing layer 12.

In some embodiments, the microspheres may be a polyurethane microsphere blowing agent, the polyurethane microspheres comprising a polyurethane shell and a gas encapsulated therein, forming tiny spherical plastic particles, which soften when heated and expand the gas within the shell, causing the expanded microspheres to increase in volume and become a 100% enclosure and return to their original volume after the pressure is released. The polyurethane microsphere foaming agent has a foaming temperature of, for example, 80-190 ℃ and a diameter of, for example, 0.7-1.4. mu.m, such as 0.8. mu.m, 1 μm. The microspheres may be formed from acrylonitrile or a copolymer of acrylonitrile, and further include isobutane, 2, 4-dimethylbutane, 2-methylpentane, 3-methylpentane, n-hexane, cyclohexane, heptane, isooctane, or any combination thereof in the raw material components of the microspheres, or other suitable polymeric microspheres, such as those prepared by emulsion polymerization, emulsified to obtain polymeric particles, which are then sieved and dried to obtain the microspheres, wherein the average particle diameter of the polymeric particles may be 0.02-0.05mm, such as 0.02-0.05 mm.

As shown in fig. 4 to 6, the penetration thickness of the air cushion layer 12 on the first substrate layer 11 is equal to or less than the thickness of the first substrate layer 11, which specifically means that there is no penetration of the glue layer paste of the air cushion layer 12 on the other side of the first substrate layer 11, and is further smaller than the thickness of the first substrate layer 11, for example, the penetration thickness of the air cushion layer 12 on the second fabric layer 113 may be equal to or less than the thickness of the second fabric layer 113, specifically, for example, 0mm, 0.06mm, 0.1mm, 0.2mm, 0.35 mm. When the penetration thickness of the air cushion layer 12 on the first substrate layer 11 is smaller than or equal to the thickness of the first substrate layer 11, and the first substrate layer 11 is taken as the innermost layer, the surface of the first substrate layer 11 is prevented from being uneven due to the penetration of the air cushion layer 12, so that the printing quality is not ideal.

As shown in fig. 2, the air cushion layer 12 is located between the first substrate layer 11 and the second substrate layer 13, and the interlayer adhesion between the first substrate layer 11 and the second substrate layer 13 should have an adhesive force of 1.5KN/m or more, and further 1.8KN/m or more, based on the air cushion layer 12, so that the ink transfer medium 10 is prevented from being broken by a radial force during use. Specifically, the air bearing layer 12 within the above range can solve the balance between the adhesion and the slurry bleeding, and further, for example, the use of a raw material component containing an organic solvent can be avoided during the production and the application of the air bearing layer 12.

As shown in FIG. 2, said first stepTwo substrate layers 13 are disposed on the air cushion layer 12, and the second substrate layer 13 may comprise, for example, a multi-layer structure formed by cloth and an adhesive, which has the same structure as the first substrate layer 11, but may be, for example, only one cloth layer, and the cloth layer may have the same structure as the first cloth layer 111, for example, long-staple cotton cloth, hemp cloth, non-woven cloth, and the like, for example, long-staple cotton cloth, and further, have a thickness of 0.3-0.5mm, such as 0.35mm, 0.37mm, 0.39mm, 0.4mm, and have cloth seams (i.e., gaps between the warp and the weft) of 0.03 mm-0.8 mm, such as 0.04mm, 0.06mm, 0.069mm, and have a thickness of 180-250g/m²Gram weight of (2), e.g. 200g/m²、220g/m²Has a radial strength of 1800 or more, further 1900 or more, for example 1950, 2000, 2200 and, more importantly, the third substrate layer 13 has a radial elongation of 5% or less, further 4.8% or less, for example 4.5%, 4%, and has a constant elongation of 1.6% or less, further 1.5% or less, for example 1.4%, 1.3%.

As shown in fig. 2, 7-8, the size layer 14 is located on the second substrate layer 13, and the size layer 14 is the outermost layer of the ink transfer medium 10, directly contacts the ink, and transfers it to the printing material 103. The surface of the topcoat layer 14, that is, the surface of the ink transfer medium 10, in some embodiments, from the viewpoint of obtaining the ink transfer medium 10 with hardness, wear resistance, oil erosion resistance, chemical corrosion resistance, and the like, the surface roughness Ra of the topcoat layer 14 is 0.8 to 1.4um, such as 0.9um, 1.0um, 1.3um, the section roughness, such as Rz, is 3 to 5um, the variation of the unevenness is less than or equal to 0.03mm, further, such as less than or equal to 0.02mm, and the shore a hardness is, for example, 70 ° to 85 °, such as 76 °, 78 °, 81 °.

In some embodiments, the raw material components of the surface adhesive layer 14 include a first nitrile rubber and/or a second nitrile rubber, a nanomaterial, zinc chloride, stearic acid, a plasticizer, an anti-aging agent and/or an anti-aging agent white carbon black and/or light calcium carbonate, a first colorant, a second colorant, sulfur, a first accelerator, a second accelerator, and a scorch retarder, and the surface adhesive layer 14 can be obtained by mixing and vulcanizing the raw material components.

In the invention, the nano silicon dioxide is amorphous white powder, is nontoxic, tasteless and pollution-free, and has a spherical microstructure and a flocculent and reticular quasi-particle structure. The graphene has good resistance to ink penetration, and can enhance the performances of ink erosion resistance and chemical corrosion resistance. The carbon nanotube has a special structure, the radial dimension is nanometer magnitude, the axial dimension is micrometer magnitude, and both ends of the tube are basically sealed. The carbon nanotube mainly comprises several layers to tens of layers of coaxial circular tubes formed by carbon atoms arranged in a hexagon, wherein a fixed distance is kept between the layers, the distance is about 0.34nm, and the diameter is generally 2-20 nm. When the nano material is the combination of graphene and nano silicon dioxide, the network structure of the nano silicon dioxide is matched with the honeycomb structure of the graphene, so that the hardness, the wear resistance and other properties of the surface adhesive layer 14 are further enhanced. When the nano material is a combination of the carbon nano tube and the nano silicon dioxide, the nano silicon dioxide can be adsorbed on the tube wall of the carbon nano tube, and the hardness, the wear resistance and other properties of the system can be further enhanced, so that the surface adhesive layer 14 has a good ink transfer effect.

As shown in fig. 8, the thickness of the surface adhesive layer 14 is, for example, 0.15 to 0.5mm, such as 0.15mm, 0.23mm, 0.33mm, and 0.45mm, when the surface adhesive layer 14 provided by the present invention is formed on the second substrate layer 13, the surface adhesive layer 14 and the second substrate 13 do not penetrate into each other, that is, the surface roughness Ra of the surface adhesive layer 14 is 0.8 to 1.4nm, and the variation of the unevenness is less than or equal to 0.03mm, so as to avoid the texture structure of the second substrate 13 from being transferred to the printing material 103, which results in an unsatisfactory printing effect.

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 measuring 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.

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.

According to the invention, 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 assembly 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 assembly, the flatness and the 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 assembly may include a plurality of sanding rollers 401 and a plurality of guide rollers 404. When the ink transfer medium 10 enters the polishing assembly, it first contacts the polishing roller 401 and sequentially passes through the polishing rollers 401, for example, the upper and lower surfaces of the ink transfer medium 10 respectively contact different polishing rollers 401, so that both the upper and lower surfaces of the ink transfer medium 10 can be polished.

As shown in fig. 20, in this embodiment, a pressure sensor 402 may be further provided at the second burnishing roller 401 (second burnishing roller), 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 (e.g., the second polishing roller) is decreased (i.e., is less than the threshold), 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 become large (i.e., greater than the threshold), that is, the unwinding speed is less 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. In this embodiment, the pressure sensor 402 is disposed on the second polishing roller, and the second polishing roller is close to the unwinding roller 101, so as to improve the accuracy of pressure detection.

In this embodiment, when the ink transfer medium 10 is offset from the scrub roller 401, for example, when the ink transfer medium 10 is offset from the scrub roller 401 by a distance of 5mm, the position of the ink transfer medium 10 can be corrected by the deviation corrector 402.

As shown in fig. 20, in the present embodiment, the ink transfer medium 10 is moved by the polishing roller 401 and the guide roller 404, and when the ink transfer medium 10 passes through the polishing roller 401, the ink transfer medium 10 can be polished, so that a smoother ink transfer medium can be obtained. During the sanding process, the dust generated can also be drawn away by suction fan 405, thereby reducing the impact of the dust on ink transfer medium 10. The suction fan 405 may be positioned above the sanding assembly. It should be noted that the arrows in the sanding assembly indicate the direction of movement of the ink transfer medium 10.
