Description

Technical Field

[0001] The invention relates to the technical field of paper calendering, and in particular to a high-density paper calendering device and process. Background Art

[0002] The calender is a device used to improve the glossiness of paper surface. It is a kind of calendering and glazing process. After the surface of the printed matter is coated, wait for the glazing layer to dry. If the smoothness and glossiness of the glazing coating need to be improved again, it can be calendered by the calender. Generally, the glossiness of glazing is about 65-85%. After calendering, the glossiness can reach more than 90-95%. The working mode of the calender is usually continuous rolling. The printed matter is transported from the paper feeding table to the calendering belt between the hot pressing roller and the pressure roller. Under the action of temperature and pressure, the coating adheres to the surface of the calendering belt and is calendered. After calendering, the glazing layer gradually cools down to form a bright surface layer.

[0003] The Chinese patent application number 201910065914.9 discloses a paper smoothing calendering device in the paper processing process, including a frame, a guide wheel mechanism, a preheating mechanism, and a calendering mechanism are arranged on the frame, and the paper passes through the guide wheel mechanism, the preheating mechanism, and the calendering mechanism in sequence, and finally outputs the paper; the calendering mechanism includes a main pressing roller and an auxiliary pressing roller, the main pressing roller includes an outer cylinder and an inner cylinder, the gap between the outer cylinder and the inner cylinder forms a heating channel, the outer cylinder is driven to rotate by a driving motor, the inner cylinder is statically arranged in the outer cylinder, and an oil inlet and outlet cylinder is also arranged in the inner cylinder, one end of the oil inlet and outlet cylinder is sealed and fixed with one end of the inner cylinder, connected to the oil supply system and the oil return system, the oil inlet and outlet cylinder is connected to the heating channel through a plurality of oil channels, and the outer cylinder, the inner cylinder and the oil inlet and outlet cylinder are coaxially arranged. The calendering device can ensure the uniformity of the roller surface temperature, thereby reducing energy consumption and improving the calendering effect.

[0004] The heating effect of the hot pressing rollers of the above-mentioned technologies on the paper is limited, and the calendering effect of the paper is not ideal. Moreover, the tension and wrinkle degree of the paper may change during the calendering process, which may affect the final calendering effect of the paper. Furthermore, since the heat source enters from one end and is discharged from the other end, during the heat conduction process, the heat loss will affect the uniformity of the temperature on the hot pressing roller surface, and also affect the hot pressing quality of the paper.

[0025] Technical effects and advantages of the present invention:

[0026] 1. The present invention sets a support component, and a heat-conducting component and an adjusting component are set on one side of the support component. The heat-conducting component can heat and squeeze the paper to achieve the purpose of calendering the paper, and the adjusting component can adjust the tension of the paper to ensure the calendering effect of the paper. The heat-conducting component includes a heat-conducting pipe, and a plurality of heat-conducting fins are set inside the heat-conducting pipe. After the high-temperature steam enters the heat-conducting pipe, it can exchange heat with the heat-conducting fins to achieve heating of the heat-conducting pipe, and the heat-conducting pipe can heat the raw paper by heat transfer. The setting of the heat-conducting fins improves the heat exchange efficiency between the high-temperature steam and the heat-conducting pipe, thereby improving the heating efficiency of the heat-conducting component on the paper, and further improving the calendering effect of the paper;

[0027] 2. The present invention sets a heat-conducting component, wherein two heat-conducting components are set, and the heat-conducting component includes a mounting plate, and a connecting seat is set on one side of the mounting plate, and the connecting seat is set on the supporting component through a pin shaft, and a hydraulic rod is also set on one side of the mounting plate. The setting of the hydraulic rod and the connecting seat enables the heat-conducting component to rotate around the pin shaft, so that the two heat-conducting components can move relative to each other, and then the two heat-conducting components can apply pressure to the paper from two directions. Compared with the traditional calendering machine using a hot roller and a pressure roller to calender the paper, the present application heats and pressurizes the paper at the same time through the heat-conducting component, simplifies the device structure, and facilitates the maintenance of the device;

[0028] 3. The present invention provides a heat-conducting pipe, and a fixed pipe is provided inside the heat-conducting pipe. The fixed pipe can guide the high-temperature steam. A fixed rod is provided inside the fixed pipe, and a guide part with a spiral structure is provided outside the fixed rod. The setting of the guide part can guide the high-temperature steam, so that the high-temperature steam can move in the heat-conducting pipe along a spiral path, thereby improving the contact surface between the high-temperature steam and the heat-conducting fins, thereby further improving the heat conduction efficiency of the heat-conducting component.

The fixed guide section is a solid structure, and the adjustable guide section is a hollow structure of an expansion material. The hollow structure of the adjustable guide section is connected to the inside of the adjustment roller through an air inlet and an air inlet pipe. After the adjustment roller is squeezed and deformed, the air inside it is squeezed and enters the hollow structure of the adjustable guide section through the air inlet pipe and the air inlet, so that the adjustable guide section expands. After the volume of the expanded adjustable guide section increases, the gap between it and the through groove is reduced, which has a better blocking effect on the flowing high-temperature steam, prolongs the time for the high-temperature steam to flow through the adjustable guide section, and increases the heat exchange time between the paper to be calendered and the high-temperature steam at this position, thereby increasing the hot pressing effect, compensating for the reduction in calendering effect caused by the above-mentioned temperature difference, and thereby maximizing the overall calendering effect of the calendered paper.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The present invention provides Figures 1 to 13A high-density paper calendering device shown includes a supporting component 1, a heat-conducting component 2, an adjusting component 3 and a raw paper 4. Two heat-conducting components 2 are provided, and the two heat-conducting components 2 are distributed up and down, and the two heat-conducting components 2 are both arranged above the adjusting component 3, and the raw paper 4 is arranged between the heat-conducting component 2 and the adjusting component 3. The heat-conducting component 2, the adjusting component 3 and the raw paper 4 are all arranged on one side of the supporting component 1.

[0046] The support assembly 1 includes a support frame 101, a support 102 is fixedly provided at the bottom end of the support frame 101; an extension frame 104 is fixedly provided at the top end of the support frame 101, and a guide roller 105 is provided on the inner side of the extension frame 104. The setting of the guide roller 105 facilitates the reversing output of the raw paper 4 after calendering treatment.

[0047] The heat conducting assembly 2 includes a heat conducting pipe 201, which is arranged on one side of the support frame 101; specifically, a mounting plate 202 is arranged at both ends of the heat conducting pipe 201, a connection seat 203 is fixedly arranged on the top of one side of the mounting plate 202, and the connection seat 203 is movably arranged on the inner wall of the support frame 101 through a pin shaft, and a hydraulic rod 204 is movably arranged on the bottom end of one side of the mounting plate 202 through a pin shaft, and the bottom end of the hydraulic rod 204 is movably arranged on the bottom end of the inner wall of the support frame 101 through a pin shaft. By adjusting the hydraulic rod 204, the hydraulic rod 204 drives the bottom end of the mounting plate 202 to move, so that the mounting plate 202 rotates around the pin shaft, and then the position of the heat conducting pipe 201 is adjusted, and the two groups of hydraulic rods 204 respectively extend or retract, so that the two heat conducting pipes 201 move closer or farther, so that the two heat conducting pipes 201 can clamp or loosen the raw paper 4.

[0048] More specifically, the heat pipe 201 is configured as a hollow structure, a connecting sleeve 205 is fixedly provided at one end of the heat pipe 201, a driving pulley 206 is fixedly provided at one end of the connecting sleeve 205, a driving motor 207 is fixedly provided on the outer side surface of the mounting plate 202, a driving pulley 208 is fixedly provided on the output shaft of the driving motor 207, and a transmission belt is provided between the driving pulley 208 and the driving pulley 206.

[0049] In addition, a fixed tube 209 is arranged inside the heat pipe 201, and the fixed tube 209 is movably arranged inside the connecting sleeve 205 through a sealed bearing. Air guide holes 210 are arranged through both ends of the outer wall of the fixed tube 209. The arrangement of the air guide holes 210 facilitates the input and output of high-temperature steam.

[0050] Moreover, a plurality of through grooves 211 are provided around the outer wall of the fixed tube 209, a fixed rod 212 is fixedly provided inside the fixed tube 209, and a guide portion 213 with a spiral structure is provided around the outer side of the fixed rod 212. The high-temperature steam enters the fixed tube 209 through the conduit 216, and the high-temperature steam moves in the fixed tube 209. During this process, the high-temperature steam moves in a spiral motion under the guidance of the spiral guide portion 213, and a part of the high-temperature steam passes through the through grooves 211 and enters the heat-conducting tube 201 during the spiral motion. There is a gap between the guide portion 213 and the inner wall of the fixed tube 209, so that on the one hand, a part of the high-temperature steam passes through the through grooves 211 and enters the heat-conducting tube 201 under the guidance of the guide portion 213; on the other hand, a part of the high-pressure steam can continue to move forward through the gap between the guide portion 213 and the inner wall of the fixed tube 209, thereby improving the uniformity of the high-temperature steam distribution in the heat-conducting tube 201, thereby ensuring the high-temperature calendering effect.

[0051] During normal operation, since high-temperature steam enters from the air guide hole 210 at one end and flows out from the air guide hole 210 at the other end, as the steam moves forward along the guide part 213, the heat gradually dissipates outward and acts on the raw paper to be calendered at high temperature. Therefore, the temperature of the air guide hole 210 near the air inlet end will actually be higher than the temperature of the air guide hole 210 near the air outlet end, and a certain temperature difference will occur at the two positions. This temperature difference is likely to cause inconsistent calendering quality on both sides of the paper when calendering wet paper with relatively large wrinkles, which is likely to affect the product quality of the calendered paper. Therefore, the structural setting of the guide part 213 is further optimized. Specifically, the guide portion 213 includes a fixed guide section 2131 and an adjustable guide section 2132. The fixed guide section 2131 is a solid structure, and the adjustable guide section 2132 is a hollow structure of an expandable material. After gas is introduced into the hollow structure of the adjustable guide section 2132, the adjustable guide section 2132 will expand. After the volume of the expanded adjustable guide section 2132 increases, the gap between it and the through groove 211 is reduced, which has a better blocking effect on the flowing high-temperature steam, prolongs the time for the high-temperature steam to flow through the adjustable guide section 2131, and increases the heat exchange time between the paper to be calendered and the high-temperature steam at this position, thereby increasing the hot pressing effect, compensating for the reduced calendering effect caused by the above-mentioned temperature difference, and thereby maximizing the overall calendering effect of the calendered paper.

[0052] Furthermore, a plurality of heat conducting fins 214 are fixedly provided on the inner wall of the heat conducting pipe 201 , and a gap is provided between the heat conducting fins 214 and the outer wall of the fixed pipe 209 . The setting of the gap prevents the heat conducting fins 214 from being affected by the fixed pipe 209 when rotating with the heat conducting pipe 201 .

[0053] Furthermore, the heat-conducting fins 214 are arranged in a "<" structure, and a plurality of through holes 215 are penetrated through the outer wall of the heat-conducting fins 214, and the through holes 215 are arranged in a conical structure with a larger outer side and a smaller inner side. The setting of the conical structure increases the area of ​​the inner wall of the through hole 215, thereby increasing the contact area between the through hole 215 and the high-temperature steam, thereby improving the heat conduction efficiency of the heat-conducting fins 214.

[0054] In addition, a conduit 216 is fixedly provided at the groove of the through hole 215, and a blocking rod 217 is fixedly provided between the two mounting plates 202. The blocking rod 217 can play a certain blocking and protective role for the heat pipe 201 to prevent the staff from accidentally touching the heat pipe 201 and getting injured. At the same time, the blocking rod 217 can also connect the two mounting plates 202 to improve the structural strength of the heat conducting component 2.

[0055] The adjusting component 3 includes an adjusting roller 301, which is arranged above the support 102. By adjusting the height of the adjusting roller 301, the tension of the raw paper 4 can be adjusted to provide conditions for better calendering of the raw paper. Specifically, a slide groove 103 is opened through the outer wall of the support frame 101, and movable seats 302 are arranged at both ends of the adjusting roller 301. A lifting cylinder 303 is fixedly arranged at the bottom end of the movable seat 302, and the lifting cylinder 303 is fixedly arranged on the upper surface of the support 102.

[0056] More specifically, a slider 304 is fixedly provided on one side of the movable seat 302, and the slider 304 is arranged in the slide groove 103. The slide groove 103 cooperates with the slider 304 so that the movable seat 302 can slide up and down, and the slider 304 and the slide groove 103 are both arranged in a "⊥" shape structure, thereby ensuring the installation strength of the movable seat 302 in the horizontal direction, and further ensuring the stability of the paper during the calendering process.

[0057] When high-density paper is calendered at high temperature, the spacing between the two heat-conducting tubes 201 is adjusted by two sets of hydraulic rods 204 according to the wrinkle degree of the wetted paper to be calendered, so that the two heat-conducting tubes 201 are squeezed and contacted with each other (the squeezing degree of the two heat-conducting tubes 201 can be controlled by controlling the two hydraulic rods 204 to ensure that the forward transmission and winding of the raw paper 4 are not affected while the raw paper 4 is calendered at high temperature), and the raw paper 4 is calendered during its forward movement. According to the size of the wrinkles on the raw paper 4 to be calendered, the squeezing degree of the two heat-conducting tubes 201 is adjusted by the two sets of hydraulic rods 4, thereby adjusting the calendering effect on the raw paper 4.

[0058] Furthermore, after the two heat conducting tubes 201 are adjusted to a suitable spacing by the two sets of hydraulic rods 204, the adjusting roller 301 is adjusted to a first height by the lifting cylinder 303, so that the adjusting roller 301 is pressed and contacted with the heat conducting tube 201 above it. In this way, the wetted raw paper 4 is firstly calendered by the adjusting roller 301 and the heat conducting tube 201 pressed and contacted therewith, and then is calendered twice by the two pressed heat conducting tubes 201, thereby improving the calendering effect on the raw paper 4.

[0059] Furthermore, when the material of the raw paper 4 changes or the surface wrinkles become larger and the calendering effect needs to be improved, the adjusting roller 301 is adjusted to a second height through the lifting cylinder 303, and the second height is greater than the first height, so that the adjusting roller 301 is further squeezed on the heat pipe 201, and the squeezing force causes the elastic material adjusting roller 301 to deform. Since the hollow structure of the adjusting guide section 2132 is connected to the inside of the adjusting roller 301 through the air inlet hole 2133 and the air inlet pipe. After the adjustment roller 301 is deformed, the air inside it is squeezed and enters the hollow structure of the adjustment guide section 2132 through the air inlet pipe and the air inlet hole 2133, causing the adjustment guide section 2132 to expand. After the volume of the expanded adjustment guide section 2132 increases, the gap between it and the through groove 211 is reduced, which has a better blocking effect on the flowing high-temperature steam, prolongs the time for the high-temperature steam to flow through the adjustment guide section 2131, and increases the heat exchange time between the paper to be calendered and the high-temperature steam at this position, thereby increasing the hot pressing effect, compensating for the reduction in calendering effect caused by the above-mentioned temperature difference, and thereby maximizing the overall calendering effect of the calendered paper. At the same time, the further squeezing of the adjustment roller 301 and the heat-conducting pipe 201 below can also better improve the calendering effect on the raw paper.

[0060] Furthermore, during the inspection and maintenance of the device, the distance between the two heat-conducting tubes 201 is adjusted by two sets of hydraulic rods 204, so that when the two heat-conducting tubes 201 are squeezed and contacted, when the two heat-conducting tubes 201 rotate in opposite directions, they can clean each other from the paper fluff or debris accumulated on their surfaces, thus creating conditions for better heat conduction of the two heat-conducting tubes 201; similarly, the height of the lower heat-conducting tube 201 is adjusted by a set of hydraulic rods 204 at the bottom and the height of the adjusting roller 301 is adjusted by the lifting cylinder 303, so that the two heat-conducting tubes 201 are squeezed and contacted. In the process of the lower heat-conducting pipe 201 driving the adjusting roller 301 to rotate, the paper fluff or debris accumulated on the surface of the lower heat-conducting pipe 201 can be cleaned up, thereby creating conditions for better heat conduction of the lower heat-conducting pipe 201; similarly, the height of the upper heat-conducting pipe 201 is adjusted by a group of hydraulic rods 204 at the top, so that it is squeezed and contacted with the guide roller 105. In the process of the upper heat-conducting pipe 201 driving the guide roller 105 to rotate, the paper fluff or debris accumulated on the surface of the upper heat-conducting pipe 201 can be cleaned up, thereby creating conditions for better heat conduction of the upper heat-conducting pipe 201.

[0061] In addition, the present invention also provides a calendering process for a high-density paper calendering device, comprising the following steps:

[0062] Step 1: feeding, pulling the paper to be calendered into the device, so that the raw paper 4 in the unloading mechanism passes through the adjustment component 3, the two heat-conducting components 2 and the guide roller 105 in sequence and then reaches the receiving mechanism;

[0063] When the raw paper 4 is pulled, the raw paper 4 is led out from the unloading mechanism, and then the raw paper 4 passes through the adjusting roller 301 and the two heat conducting pipes 201 in sequence, and then passes through the guide roller 105, and finally reaches the winding mechanism, so that the pulling and placing of the raw paper 4 is completed;

[0064] Step 2: tension adjustment: by adjusting the position of the adjusting component 3, the position between the adjusting component 3 and the heat conducting component 2 is adjusted, thereby adjusting the tension of the raw paper 4;

[0065] After the raw paper 4 is pulled, the lifting cylinder 303 is adjusted to make the movable seat 302 move downward, and the movable seat 302 drives the adjusting roller 301 to move downward. Since both ends of the raw paper 4 are restricted by the unwinding mechanism and the winding mechanism respectively, the raw paper 4 is in a tensioned state in the adjusting component 3 and the heat conducting component 2. When the adjusting roller 301 moves, the position between the adjusting roller 301 and the heat conducting pipe 201 changes, so that the tension of the raw paper 4 is adjusted.

[0066] Step 3: Pressure adjustment: by adjusting the position between the two heat-conducting components 2, the two heat-conducting components 2 press the raw paper 4 from two directions;

[0067] When adjusting the position of the heat conducting component 2, the hydraulic rod 204 is adjusted so that the hydraulic rod 204 drives the bottom end of the mounting plate 202 to move, so that the mounting plate 202 rotates around the pin shaft, and the position of the heat conducting tube 201 is adjusted. The two groups of hydraulic rods 204 extend and retract respectively, so that the two heat conducting tubes 201 move toward each other, and the two heat conducting tubes 201 can clamp the raw paper 4.

[0068] Step 4: calendering treatment, by conveying high-temperature steam to the heat-conducting component 2, the heat-conducting component 2 heats the paper and pulls the raw paper 4 at the same time. At this time, the heated raw paper 4 is squeezed by the two heat-conducting components 2, so as to achieve the effect of calendering treatment on the raw paper 4;

[0069] When the heat-conducting component 2 heats the raw paper 4, the high-temperature steam enters the fixed pipe 209 through the conduit 216, and the high-temperature steam moves in the fixed pipe 209. In this process, the high-temperature steam moves in a spiral motion under the guidance of the spiral guide part 213. During the spiral motion, the high-temperature steam passes through the through groove 211 and enters the heat-conducting pipe 201. The high-temperature steam in the heat-conducting pipe 201 contacts the heat-conducting fins 214. At this time, the heat in the high-temperature steam is transferred to the heat-conducting fins 214 by heat transfer, and then the heat is transferred to the heat-conducting pipe 201 through the heat-conducting fins 214, and then transferred to the raw paper 4 through the heat-conducting pipe 201. At this time, the raw paper 4 can be heated;

[0070] After the raw paper 4 is heated, the driving motor 207 drives the driving pulley 208 to rotate, and the driving pulley 208 drives the driving pulley 206 to rotate through the transmission belt, thereby driving the heat pipe 201 to rotate, so that the heat pipe 201 rotates around the fixed tube 209. The heat pipe 201 can achieve auxiliary traction of the raw paper 4 during the rotation process. During this process, the winding mechanism pulls the raw paper 4 at the same speed, thereby achieving calendering treatment of the raw paper 4.
