Description

Technical Field

[0001] The invention relates to the technical field of paper calenders, and in particular to an intelligent paper calender with controllable middle and high roller zones. Background Art

[0002] During the pressurization process, the rollers of the paper calender will bend and deform due to the uniform load generated by their own weight and the external load applied to the bearings, resulting in the largest deflection in the middle, which in turn makes the pressure distribution in the entire pressure zone uneven. In order to solve this problem, most of the current technologies use intelligent controllable middle and high rollers, such as swimming rollers, controllable middle and high rollers, and zoned controllable rollers.

[0003] However, in the actual use of the calender, some shortcomings were found: when processing paper, static electricity is generated due to the continuous rolling friction between the pressure roller and the paper, which causes the pressure roller to absorb dust particles in the air, especially larger particles may be pressed into the paper during the process of the pressure roller rolling the paper, thus affecting the calendering effect; in addition, in order to reduce the occurrence of this situation, the pressure roller needs to be cleaned and maintained regularly, but the maintenance work requires downtime, which will affect the production cycle and efficiency.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] In the above scheme, by setting up a dust removal mechanism, the dust on the surface of the roller can be vacuumed during its rotation, thereby preventing the dust from being pressed into the inside of the paper and affecting the calendering effect; and the dust removal mechanism maintains the dust suction treatment method to effectively reduce the dust on the surface of the roller, thereby eliminating the need to stop the machine for cleaning and maintenance.

[0015] By setting up a cleaning component, the second rotating rod is used to rotate the arc tube to blow and suck air, and the dust on the surface of the roller body is sucked away by suction; and when sucking air, the air sucks the dust on the roller body into the arc plate through the through hole, and some dust accumulates in the dust box at the bottom end of the arc plate, and some dust follows the air inlet pipe into the arc tube. In this process, the filter isolates the dust in the incoming air to prevent the dust from accumulating in the arc tube for a long time; the filter is vibrated by blowing air, so as to achieve the purpose of cleaning the filter, which is further beneficial to dust collection.

[0016] By setting up multiple arc tubes, during the rotation process, two relatively arranged second rotating rods and the two arc tubes at the corresponding positions are squeezed and contacted. When the two arc tubes are no longer squeezed, the two second rotating rods continue to squeeze the two arc tubes at the next position. Therefore, continuous suction can be maintained during the process of suction and dust collection.

[0017] By opening an air leak hole on the second air outlet pipe, when the second air outlet pipe blows air into the collection tank, part of the air is discharged through the air leak hole. On the one hand, it prevents too much air from being blown into the collection tank, causing a large amount of dust to enter the air intake pipe. On the other hand, it allows the air in the hollow area to be discharged normally, so that the air intake pipe can normally take in air.

[0018] By setting a rubber tube made of anti-static rubber close to the surface of the roller, it helps to eliminate static electricity on the surface of the roller; in addition, the rubber tube is filled with coolant, which helps to maintain its temperature stable, further reduce the generation of static electricity, and thus facilitate dust collection.

[0044] like Figures 1 to 16 As shown, an embodiment of the present invention provides an intelligent papermaking calender that is easy to control in the middle and high roller partitions, including a calender body 1 and a power mechanism, the power mechanism is a device used in the calender body 1 in the prior art, and a pair of rollers 2 arranged up and down are installed on the calender body 1, the power mechanism drives the pair of rollers 2 to rotate, and the paper is calendered when passing between the pair of rollers 2; it also includes a dust removal mechanism, the dust removal mechanism includes a pair of arc plates 29 with hollow interiors, a plurality of through holes are opened on the surface of the arc plates 29 close to the rollers 2, a detachable dust box is provided at the bottom end of the arc plates 29, the pair of arc plates 29 are respectively covered on the pair of rollers 2, and the through holes are close to the rollers 2, dust is processed during the rotation of the rollers 2, and the dust removal mechanism is installed on the calender body 1.

[0045] like Figures 6 to 9As shown, the dust removal mechanism also includes a driving component and a cleaning component. The cleaning component includes a pair of mounting frames 6, a first rotating rod 7 is rotatably connected between the pair of mounting frames 6, and a fixed sleeve 8 is fixedly connected to the outer periphery of the first rotating rod 7, a rubber sleeve 11 is fixedly connected to the fixed sleeve 8, and a plurality of integrated arc tubes 12 are fixedly connected to the inner peripheral side wall of the rubber sleeve 11. The arc tubes 12 are made of elastic rubber material, and a hollow area 13 is provided in each of the plurality of arc tubes 12; a pair of brackets 9 are fixedly connected to the outer peripheral side wall of the first rotating rod 7, and a pair of brackets 9 are rotatably connected to the inner peripheral side wall of the first rotating rod 7. A second rotating rod 10 is movably connected to the roller body 2 and is in compression contact with the rubber sleeve 11; an annular tube 14 is fixedly connected to the outer peripheral side wall of the fixed sleeve 8, and a first air outlet pipe 16 and a plurality of inserting tubes 15 are fixedly connected to the annular tube 14, and the plurality of inserting tubes 15 all pass through the fixed sleeve 8 and are connected to the hollow area 13; one end of the first air outlet pipe 16 away from the annular tube 14 is connected to the arc plate 29, and a pair of air inlet pipes 36 are also arranged between the first air outlet pipe 16 and the roller body 2, one end of the pair of air inlet pipes 36 are connected to the first air outlet pipe 16, and the other ends of the pair of air inlet pipes 36 are respectively connected to a pair of arc plates 29.

[0046] Since the first rotating rod 7 is rotatably connected to a pair of mounting frames 6, the fixed sleeve 8 is fixed on a pair of mounting frames 6, and the first rotating rod 7 is located in the fixed sleeve 8, when the driving assembly works to drive the first rotating rod 7 to rotate, the second rotating rod 10 on the side wall of the first rotating rod 7 squeezes the surface of the arc tube 12 in the fixed sleeve 8, and the currently squeezed arc tube 12 is deformed, so that the air in the hollow area 13 is discharged outward through the first outlet pipe 16 and the inlet pipe 36. When the squeezed arc tube 12 is reset, the air enters the arc tube 12. In this process, the dust on the surface of the roller body 2 is sucked into the inlet pipe 36.

[0047] like Figures 11 to 13As shown, a ventilation component is arranged between the first air outlet pipe 16 and the air inlet pipe 36, and the ventilation component includes a first fixed pipe 17, a second fixed pipe 18 and a third fixed pipe 30, the second fixed pipe 18 is connected to the air inlet pipe 36, the first fixed pipe 17 is connected to the first air outlet pipe 16, the second fixed pipe 18 and the third fixed pipe 30 are an integrated horizontal pipe, the first fixed pipe 17 is a vertical pipe, the first fixed pipe 17 is located between the second fixed pipe 18 and the third fixed pipe 30, and an integrated pipeline structure is formed, and an air sealing component is arranged at the connection between the first fixed pipe 17 and the second fixed pipe 18 and between the first fixed pipe 17 and the third fixed pipe 30, the bottom end of the second fixed pipe 18 is fixedly connected to the mounting pipe 19, and the mounting pipe 19 is fixedly connected to the mounting pipe 19. There is a second air outlet pipe 21 connected to the third fixed pipe 30, and a detachable collecting tank 20 is installed at the bottom of the mounting tube 19. The function of one of the air sealing components is to allow the airflow in the first air outlet pipe 16 to be discharged only through the second air outlet pipe 21 during inhalation, and the function of the other air sealing component is to allow external air to enter only through the air inlet pipe 36 and the second fixed pipe 18 during inhalation; during inhalation, the air sucks the dust on the roller body 2 into the arc plate 29 through the through hole, part of the dust accumulates in the dust box at the bottom end of the arc plate 29, and part of the dust follows the air inlet pipe 36 into the arc tube 12. In this process, the filter 23 isolates the dust in the incoming air to prevent dust from accumulating in the arc tube 12 for a long time.

[0048] like Fig.12 , Fig.13 As shown, the air sealing component includes a baffle ring 26, in which an air vent 27 is provided, and a movable baffle 28 is fixedly connected to one end of the baffle ring 26, wherein the baffle 28 is made of rubber material and fits against the baffle ring 26 when not subjected to air pressure; once air pressure is applied, the baffle 28 will be pushed open, and in the absence of air pressure, the baffle 28 will return to its initial position; in addition, the baffle 28 is a circular structure adapted to the second fixed tube 18 or the third fixed tube 30, and a portion of the edge of the baffle 28 is fixed to one side of the baffle ring 26. During use, air can pass freely from the side where the baffle 28 is not installed, and at this time, the baffle 28 is pushed open under the action of air pressure to ensure air circulation; and when air passes from the side where the baffle 28 is installed, the baffle 28 is restricted by the baffle ring 26 and remains in a closed state, thereby preventing air from being discharged.

[0049] like Fig.12As shown, a first fixed ring 22 is fixedly connected inside the second fixed tube 18, a filter screen 23 is fixedly connected inside the first fixed ring 22, a second fixed ring 24 is fixedly connected to the filter screen 23, and one end of the second fixed ring 24 is fixedly connected to a fixing plate 25 extending into the collection tank 20, wherein the second fixed ring 24 does not contact the first fixed ring 22; when the air in the arc tube 12 is discharged, the air will enter the mounting tube 19 through the second air outlet pipe 21. Since the second air outlet pipe 21 is facing the fixing plate 25 in the collection tank 20, the air will blow toward the fixing plate 25 when entering the mounting tube 19, so that the fixing plate 25 drives the filter screen 23 to shake, thereby causing the dust on the filter screen 23 to be shaken off into the collection tank 20.

[0050] In addition, since there are multiple arc tubes 12, during the rotation process, two oppositely arranged second rotating rods 10 and the two arc tubes 12 at the corresponding positions are squeezed and contacted. When the two arc tubes 12 are no longer squeezed, the two second rotating rods 10 continue to squeeze the two arc tubes 12 at the next position. Therefore, continuous suction can be maintained during the process of suction and vacuuming.

[0051] like Fig.12 As shown, a plurality of air leakage holes 35 are provided on the side wall of the second air outlet pipe 21, and the third fixed pipe 30, the second air outlet pipe 21 and the mounting pipe 19 form an air passage, and the plurality of air leakage holes 35 are connected to the air passage. By providing the air leakage holes 35 on the second air outlet pipe 21, when the second air outlet pipe 21 blows air into the collecting tank 20, part of the air is discharged through the air leakage holes 35. On the one hand, it prevents too much air from being blown into the collecting tank 20, causing a large amount of dust to enter the air inlet pipe 36, and on the other hand, it allows the air in the hollow area 13 to be discharged normally, so that the air in the air inlet pipe 36 can be normally inhaled.

[0052] like Fig.15 , Fig.16 As shown, a pair of the arc plates 29 each include an inner cavity 38, and a plurality of through holes are fixedly connected with a rubber tube 31, and the rubber tube 31 is connected to the inner cavity 38; the end of the rubber tube 31 close to the roller body 2 expands outward to form a cover mouth 32, and an annular hole 33 is provided in the cover mouth 32, and a coolant is filled in the annular hole 33, and a notch 34 adapted to the arc surface of the roller body 2 is provided on the bottom wall of the cover mouth 32, and the notch 34 helps the roller body 2 to approach the rubber tube 31; the rubber tube 31 is made of anti-static rubber, and when it approaches the surface of the roller body 2, it helps to eliminate static electricity on the surface of the roller body 2; in addition, the rubber tube 31 is filled with coolant, which helps to maintain its temperature stability and further reduce the generation of static electricity.

[0053] like Figures 1 to 3As shown, the driving assembly includes a first pulley 3 connected to the power mechanism on the calendering machine body 1, and a second pulley 4 fixedly connected to the two ends of the first rotating rod 7, and a transmission belt 5 is tensioned between the first pulley 3 and one of the second pulleys 4; the power mechanism on the calendering machine body 1 is a prior art structure. When working, the power mechanism drives the roller body 2 to rotate, which is not repeated here; the first pulley 3 and one of the second pulleys 4 are tensionedly connected by a transmission belt 5, and when the roller body 2 rotates, the first rotating rod 7 is driven to rotate by the cooperation of the first pulley 3, the second pulley 4 and the transmission belt 5; the rotation speed of the first rotating rod 7 is consistent with the roller body 2, and the driving assembly can be replaced by the prior art structure to drive the first rotating rod 7. When using other structures for driving, it is necessary to adjust to an appropriate rotation speed to prevent the rotation speed from being too fast, affecting the normal discharge of airflow and the inhalation of dust; the two second pulleys 4 are respectively arranged at the upper and lower ends of the first rotating rod 7, playing the role of counterweights to maintain the rotation balance of the first rotating rod 7.

[0054] like Fig.10 As shown, the top of the arc plate 29 is fixedly connected to an external pipe 37, and the external pipe 37 includes a plurality of atomizing nozzles extending into the inner cavity 38. The external pipe 37 can be connected to an external water supply mechanism to realize the water supply function. The water supply mechanism and the adjustment of the water supply amount are both existing technologies. The water supply amount is accurately controlled by a programmable system and will not be described in detail. After the water enters the external pipe 37, it is sprayed in the inner cavity 38 through the atomizing nozzle, and contacts with the surface of the roller body 2 through the rubber tube 31 to increase the wettability, thereby enhancing the calendering effect and eliminating static electricity.

[0055] The working principle of the technical solution provided by the present invention is as follows: when the roller body 2 rotates, the driving assembly drives the first rotating rod 7 to rotate, and at the same time, the second rotating rod 10 squeezes the surface of the arc tube 12 in the fixed sleeve 8, and the arc tube 12 currently being squeezed is deformed, so that the air in the hollow area 13 is discharged outward through the first air outlet pipe 16 and the air inlet pipe 36; when the squeezed arc tube 12 is reset, the air enters the arc tube 12, and in this process, the air sealing component between the first fixed tube 17 and the third fixed tube 30 is in a closed state, and the air sealing component between the first fixed tube 17 and the second fixed tube 18 is in an open state, and the dust on the surface of the roller body 2 is sucked into the arc plate 29 through the air inlet pipe 36, part of the dust accumulates in the dust box at the bottom end of the arc plate 29, and part of the dust follows the air inlet pipe 36 into the arc tube 12, and the filter 23 isolates the dust in the incoming air to prevent the dust from accumulating in the arc tube 12 for a long time.

[0056] During exhaust, the air sealing component between the first fixed pipe 17 and the third fixed pipe 30 is in an open state, and the air sealing component between the first fixed pipe 17 and the second fixed pipe 18 is in a closed state. The air enters the mounting pipe 19 through the second air outlet pipe 21 and blows toward the fixing plate 25, so that the fixing plate 25 drives the filter screen 23 to shake, so that the dust on the filter screen 23 is shaken off into the collection tank 20.

[0057] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
