Description

Technical Field

[0001] This invention relates to the field of papermaking machinery technology, and in particular to a high-gloss grey cardboard production equipment with an integrated calendering and cooling system. Background Technology

[0002] The calendering and cooling steps in the production equipment for high-gloss grey cardboard are key steps in forming its unique surface. After preliminary forming and drying, the cardboard enters a multi-roll calender for finishing. In this step, the cardboard passes through a series of high-precision, highly polished metal rollers under high temperature and high pressure. These rollers intensely crush and rub the surface of the cardboard, making its fiber structure tightly compacted, thereby obtaining extremely high smoothness and gloss. Immediately afterwards, the hot cardboard that has undergone calendering enters the cooling stage. Through direct contact with the surface of large-area cold metal rollers, the cardboard is cooled down rapidly and evenly.

[0003] The present invention, CN1768180B, relates to a method for manufacturing paper / paperboard that re-wets the paper web / paperboard at a location between wet pressing (I) and rewinding (VI), and to an apparatus for implementing the method. In this method, prior to re-wetting, the paper web / paperboard is calendered and / or dried in at least one operation (III) using a processing assembly (1) of the type of metal belt calender. The processing assembly (1) includes a metal belt (2) adapted to travel around at least one guide member (3), with at least one reaction member (5) disposed on the outside of the metal belt, forming a contact surface with the metal belt, thereby establishing a paper web processing area (N) between the metal belt and the reaction member, through which the paper web to be processed passes. In this processing assembly, the length of the processing area is adjusted by providing the metal belt guide member and / or shaping the reaction member. In a subsequent process after re-wetting (IV), the paper web / paperboard is finally calendered (V) using a desired calendering technique.

[0004] However, in the production process of high-gloss grey cardboard, the traditional process separates the calendering and cooling processes. After high-temperature calendering, the cardboard needs to be transferred to the cooling unit by a conveyor device. During this process, the cardboard is exposed to the air for a long time and is prone to reabsorbing moisture due to the ambient humidity, resulting in a decrease in surface gloss and poor stability, which affects the processing quality of grey cardboard. Summary of the Invention

[0005] In view of this, the present invention provides a high-gloss grey cardboard production equipment with an integrated calendering and cooling system. This equipment integrates the calendering and cooling processes into a single unit, completely eliminating the transmission gap caused by the cardboard being exposed to air after high-temperature calendering, effectively preventing moisture reabsorption due to environmental humidity, and improving the processing quality of grey cardboard. The anti-wrinkle spreading plate achieves efficient flattening of the cardboard before calendering through reciprocating movement and elastic pressure from the bonding spring, avoiding wrinkles. The cleaning scraper and dust collector work together to remove debris from the surface of the chrome-plated hot press rollers in real time, preventing impurities from being pressed into the cardboard surface. Combined with the uniform guidance of the limiting clamping rollers, this further ensures the structural stability of the cardboard during cooling. The preheating fan and preheating chamber work together to recover residual heat from the cooling process for cardboard preheating, reducing additional heating energy consumption. The air duct adjustment baffle can flexibly adjust the air cooling range according to the cardboard width, avoiding airflow waste during narrow-width production.

Multiple sets of dust collection inlets 105 are provided, and the multiple sets of dust collection inlets 105 are fixedly connected to the lower rear end of the dust collector 8. All sets of dust collection inlets 105 are located above the cleaning scraper 104.

[0031] The calendering auxiliary mechanism also includes: an anti-wrinkle support platform 106, an anti-wrinkle drive motor 107, an anti-wrinkle transmission gear set 108, an anti-wrinkle drive screw 109, an anti-wrinkle slide 110, and an anti-wrinkle drive slider 111; the anti-wrinkle support platform 106 is fixedly connected to the front end of the integrated support platform 1; the anti-wrinkle drive motor 107 is fixedly connected to the front end of the dust collector 8; the anti-wrinkle transmission gear set 108 consists of three sets of meshing bevel gears, the middle set of gears of the anti-wrinkle transmission gear set 108 is connected to the output shaft of the anti-wrinkle drive motor 107, and the anti-wrinkle transmission gear set 108 is rotatably connected to the dust collector 8. The front end of the dust collector 8 includes two sets of anti-wrinkle drive screws 109, both of which are reciprocating screw structures. The two sets of anti-wrinkle drive screws 109 are coaxially fixedly connected to the outer ends of the left and right gears of the anti-wrinkle transmission gear set 108. Two sets of anti-wrinkle slides 110 are also provided, fixedly connected to the left and right sides of the front end of the dust collector 8. Two sets of anti-wrinkle drive sliders 111 are also provided, slidably connected to the front end of the anti-wrinkle slides 110, and threadedly connected to the anti-wrinkle drive screws 109.

[0032] The calendering auxiliary mechanism also includes: an anti-wrinkle spreading plate 112 and an anti-wrinkle bonding spring 113; two sets of anti-wrinkle spreading plates 112 are provided, and the two sets of anti-wrinkle spreading plates 112 are slidably connected to the bottom of the anti-wrinkle drive slider 111, and the lower ends of the two sets of anti-wrinkle spreading plates 112 are made of rubber material; two sets of anti-wrinkle bonding springs 113 are provided, and the two sets of anti-wrinkle bonding springs 113 are fixedly connected to the bottom of the anti-wrinkle drive slider 111, and the lower ends of the two sets of anti-wrinkle bonding springs 113 are fixedly connected to the anti-wrinkle spreading plate 112.

[0033] The specific usage and function of this embodiment are as follows: When calendering gray cardboard, the inlet end of the gray cardboard is placed above the anti-wrinkle support platform 106. The anti-wrinkle drive motor 107 is turned on, and the output shaft of the anti-wrinkle drive motor 107 rotates, driving the anti-wrinkle transmission gear set 108 to rotate. The rotation of the anti-wrinkle transmission gear set 108 drives the anti-wrinkle drive screw 109 to rotate, and the rotation of the anti-wrinkle drive screw 109 drives the anti-wrinkle drive slider 111 to move left and right. The left and right movement of the anti-wrinkle drive slider 111 drives the anti-wrinkle spreading plate 112 to move left and right. Under the action of the anti-wrinkle bonding spring 113, the left and right movement of the anti-wrinkle spreading plate 112 keeps it in contact with the gray cardboard. At the same time, the left and right movement of the anti-wrinkle spreading plate 112 flattens the gray cardboard, avoiding wrinkles during the calendering of the gray cardboard and improving the processing quality of the gray cardboard. The cleaning scraper 104 contacts the chrome-plated hot press roller 5, realizing the cleaning of the debris on the surface of the chrome-plated hot press roller 5 and preventing the debris from being pressed into the cardboard. On the surface, the debris collected during cleaning accumulates above the cleaning scraper 104 and enters the dust collector 8 through the dust collection inlet 105. The dust collector 8 filters the debris in the air and discharges the exhaust gas. The gray cardboard completes the calendering process under the pressure of the chrome-plated hot press roller 5 and the rubber-coated pressure roller 4. The adjusting contact roller 102 realizes the tension detection of the cardboard before it enters the cooling process. Once the pressure sensor of the adjusting contact roller 102 detects that the pressure of the cardboard is too high or too low, the pressure sensor of the adjusting contact roller 102 controls the adjusting drive 103 to start. The push rod of the adjusting drive 103 extends or retracts, causing the tension adjusting link 101 to swing. The swing of the tension adjusting link 101 causes the adjusting contact roller 102 to swing. The swing of the adjusting contact roller 102 realizes the adjustment of the tension of the cardboard, while ensuring that the cardboard enters the cooling area with the optimal tension to avoid wrinkles or stretching deformation. After the tension adjustment, the cardboard comes into contact with the chrome-plated cooling roller 6 to achieve initial cooling.

[0034] Example 2: like Figures 1 to 8 As shown: The present invention provides a high-gloss grey cardboard production equipment with an integrated calendering and cooling system. Based on the first embodiment, it also includes a multi-stage cooling mechanism, which is set inside the integrated processing box 2.

[0035] The multi-stage cooling mechanism includes: an air-cooled housing 601, air duct adjusting baffles 602, air duct adjusting bolts 603, and cooling connecting pipes 604. Two sets of air-cooled housings 601 are provided, fixedly connected to the upper and lower sides of the integrated processing housing 2, respectively, and positioned behind the chrome-plated cooling rollers 6. Four sets of air duct adjusting baffles 602 are provided, slidably connected to the left and right sides of the air-cooled housing 601. Four sets of air duct adjusting bolts 603 are provided, rotatably connected to the outer side of the air duct adjusting baffles 602, and threadedly connected to the air-cooled housing 601. Two sets of cooling connecting pipes 604 are provided, fixedly connected to the outer side of the air-cooled housing 601, and connected to an external cold air duct via a tee.

[0036] The multi-stage cooling mechanism also includes a switching electric valve 605; the switching electric valve 605 is an electric T-type three-way valve structure, the switching electric valve 605 is fixedly connected to the connection position of the cooling connection pipe 604, and the drive motor of the switching electric valve 605 is a reciprocating motor structure.

[0037] The multi-stage cooling mechanism also includes: a limiting guide 606 and a cooling guide slider 607; multiple sets of limiting guides 606 are provided, and the multiple sets of limiting guides 606 are fixedly connected to the left and right sides inside the integrated processing box 2; two sets of cooling guide sliders 607 are provided, and the two sets of cooling guide sliders 607 are slidably connected to the opposite ends of the limiting guides 606.

[0038] The multi-stage cooling mechanism also includes: a limiting support spring 608 and a limiting clamping roller 609; multiple sets of limiting support springs 608 are provided, and the multiple sets of limiting support springs 608 are respectively fixedly connected to the upper and lower ends of the cooling guide slider 607, and the outer sides of the multiple sets of limiting support springs 608 are respectively fixedly connected to the limiting guide member 606; multiple sets of limiting clamping rollers 609 are provided, and the multiple sets of limiting clamping rollers 609 are respectively rotatably connected to the opposite ends of the cooling guide slider 607.

[0039] The multi-stage cooling mechanism also includes: a preheating exhaust box 610, a preheating fan 611, and a preheating housing 612; the preheating exhaust box 610 is fixedly connected to the left side of the integrated processing housing 2, and the preheating exhaust box 610 is connected to the air-cooled area inside the integrated processing housing 2; the preheating fan 611 is fixedly connected to the left side of the integrated processing housing 2, and the air inlet of the preheating fan 611 is connected to the preheating exhaust box 610; the preheating housing 612 is fixedly connected to the front end of the integrated support platform 1, and the air inlet of the preheating housing 612 is connected to the air outlet of the preheating fan 611, and the air outlet of the preheating housing 612 is connected to an external exhaust gas pipe.

[0040] The specific usage and function of this embodiment: When the gray cardboard, which has been initially cooled by the chrome-plated cooling roller 6, enters the air-cooling area, the limiting clamping roller 609 limits the gray cardboard. External cold air enters the interior of the air-cooling box 601 through the cooling connecting pipe 604. The air-cooling box 601 blows cooling air onto the gray cardboard, achieving further cooling. At the same time, the switching electric valve 605 is opened, which alternately connects the cooling pipe to the two sets of cooling connecting pipes 604, causing the cooling air from the air-cooling box 601 to alternately blow onto the gray cardboard. The limiting guide 606 and the cooling guide slider 60... Guided by 7, the gray cardboard moves slightly up and down, preventing it from sticking to the chrome-plated cooling roller 6. At the same time, by rotating the air duct adjusting bolt 603, the air duct adjusting bolt 603 drives the air duct adjusting baffle 602 to move left and right. The left and right movement of the air duct adjusting baffle 602 adjusts the width of the air duct of the air-cooled box 601, reducing the waste of cold air. The preheating fan 611 is turned on, and the preheating fan 611 introduces the cold air that has completed heat exchange into the preheating box 612 through the preheating exhaust box 610. The preheating box 612 preheats the gray cardboard, reducing the energy consumption of the entire device.
