[0002] Corrugated cardboard is a material widely used in the packaging industry. It is mainly composed of multiple layers of paper. It is light, high-strength and has good shock resistance. Cardboard drying is a key link in the production process of corrugated cardboard. The pressure of the ballast roller and the heat of the dryer can achieve uniform evaporation of moisture on the surface of the cardboard, preventing the cardboard from warping due to uneven drying. However, there are some problems with the existing cardboard drying ballast rollers, such as:

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0032] Reference Figure 1-7 A cardboard drying balanced ballast roller system for a corrugated cardboard production line comprises a frame 1, a plurality of rollers 2 are arranged in the frame 1, and a balancing mechanism 3 is arranged at the left and right outer ends of the rollers 2. The balancing mechanism 3 comprises a balancing seat 301, and the balancing seat 301 slides forward and backward in the frame 1. An adjusting mechanism 4 is arranged inside the plurality of balancing mechanisms 3 on the same side. The balancing mechanism 3 can bear the weight of the roller 2 and the dynamic load during operation through a stable supporting frame, and avoid the influence of vibration, so as to ensure stability during high-speed operation, thereby reducing jumping and impact. The designed adjusting mechanism 4 can adjust the height change according to the thickness of the cardboard to avoid excessive or insufficient pressing of the cardboard.
[0033] Furthermore, referring to Figure 6A bearing block 302 that slides up and down is arranged inside the balancing seat 301, and the roller 2 is installed between the corresponding bearing blocks 302 on both sides. A spring sheet 304 is arranged on the upper side of the bearing block 302, and a diagonal support block 309 is arranged on the upper side of the left and right ends of the spring sheet 304. Corresponding tightening blocks 310 are arranged on the outer sides of the two diagonal support blocks 309. The diagonal support blocks 309 slide left and right on the upper side of the balancing seat 301, and an inclined surface is arranged on the outer side of the diagonal support blocks 309. The tightening blocks 310 slide inside and outside on the upper side of the balancing seat 301, and corresponding inclined surfaces are arranged on the left and right sides of the inner sides of the tightening blocks 310. The adjusting mechanism 4 includes a dial bar 401, and the dial bar 401 is located at a plurality of tightening blocks 31 0, through the pull bar 401 in the tightening adjustment mechanism 4, the inner tightening blocks 310 are pushed to gather the left and right diagonal support blocks 309 inside the tightening blocks 310, thereby tightening or unfolding the lower spring sheet 304, thereby adjusting the elastic support of the lower bearing block 302. When the thickness of the paperboard is large, the diagonal support blocks 309 on both sides are adjusted to be far away, giving the spring sheet 304 a larger range of movement, and when the thickness of the paperboard is small, the diagonal support blocks 309 on both sides are adjusted to be close. At this time, the pressure of the spring sheet 304 on the lower bearing block 302 is more urgent, which is reflected on the paperboard on the lower side of the roller 2, and is also more compact;
[0034] Furthermore, referring to Figure 7 , a slide 307 located on the outside of the frame 1 is fixed on the outside of the balancing seat 301, and a balancing frame 305 located on the outside of the slide 307 is fixed on the outside of the bearing block 302. A slider that slides up and down is arranged on the outside of the slide 307, and a balancing spring 306 that is sleeved on the end of the roller 2 is arranged between the slider and the outer balancing frame 305. The balancing spring 306 is automatically adjusted according to the load change of the roller 2 to keep the roller 2 in a relatively balanced position to prevent tilting. The slider slides up and down on the slide 307 to compensate for the displacement of the roller 2 caused by the load change. The balancing frame 305 is fixed on the slide 307 to ensure that the pressure of the roller 2 is evenly distributed to prevent the deformation of the cardboard caused by excessive local pressure. The balancing spring 306 not only balances the roller 2, but also absorbs the vibration during operation, improves the stability of the system, and reduces the impact on the cardboard. The cooperation between the slider and the balancing frame 305 provides a guiding effect to ensure the consistency of the central axis of the roller 2. If the roller 2 deviates due to external factors, the spring and the slider can respond quickly to automatically adjust the height and pressure of the roller 2;
[0035] Furthermore, referring to Figure 4 , 5The adjusting mechanism 4 also includes two slides 402, which are fixed to the ends of the pull bar 401. The slides 402 slide inside and outside on the upper side of the frame 1. The frame 1 is rotatably connected with a block 408 on the outside. A torsion spring is provided at the junction of the block 408 and the frame 1, and a plurality of slots corresponding to the block 408 are provided on the surface of the slide 402. A spur gear 403 connected to the inner side of the frame 1 is provided on the lower side of the slide 402. A tooth groove meshing with the spur gear 403 is provided on the lower side of the slide 402. A bevel gear 404 is fixed on the outer side of the spur gear 403. Another bevel gear 404 meshing with the bevel gear 404 is provided on the outer side of the bevel gear 404. A knob 405 connected to the frame 1 is provided at the center of the block 408. The knob 405 is fixedly connected to another bevel gear 404 on the inner side of the frame 1. A ratchet 406 is fixed on the outer circumference of the knob 405. The block 408 A ratchet block 407 corresponding to the ratchet wheel 406 is arranged on the outside, and a torsion spring is arranged at the junction of the ratchet block 407 and the clamping block 408. The position of the lever 401 is adjusted by the adjusting mechanism 4 to adjust the spring sheet 304 in the balancing mechanism 3. The specific operation for adjusting the lever 401 inside and outside is to rotate the inner bevel gear 404 by the knob 405, and to realize the linkage of the spur gear 403 by another bevel gear 404. The spur gear 403 drives the movement of the lever 401 through the upper slide 402. The clamping block 408 and the corresponding clamping slot can realize the instant determination of the adjustment position. When the position of the lever 401 needs to be called back, the knob 405 is reversed, and the ratchet 406 on the outside of the knob 405 realizes the outward rotation of the clamping block 408 through the ratchet block 407. At this time, the slide 402 and the lever 401 connected thereto can be moved back.
[0036] Furthermore, referring to Figure 1 , 3, 6. The left and right outer sides of the frame 1 are connected to a plurality of paddles 7 corresponding to the balancing seat 301. A spur gear 6 is fixed on the inner side of the paddle 7. An adjusting rod 5 is arranged on the upper side of the plurality of spur gears 6. A plurality of tooth pieces 8 corresponding to the tooth grooves of the spur gear 6 are arranged around the adjusting rod 5. A limiting block 9 is fixed to the rear end of the adjusting rod 5, and a positioning groove block 10 corresponding to the limiting block 9 is arranged on the outer side of the frame 1. A rotating block 303 is rotatably connected to the outer side of the balancing seat 301. The paddle 7 passes through the rotating block 303 corresponding to the outer side of the balancing seat 301 on the front side, and a sliding groove corresponding to the paddle 7 is opened inside the rotating block 303. One side of the tooth piece 8 is a flat section. A plurality of limiting grooves 308 corresponding to the tooth piece 8 are opened on the lower side of the balancing seat 301, and a torsion spring is arranged at the connection of the adjusting rod 5. When it is necessary to adjust the spacing of the rollers 2, the adjusting rod 5 is turned down so that the tooth piece 8 falls into the corresponding tooth groove of the lower spur gear 6, and the adjustment is performed by pushing the adjusting rod 5 forward and backward. The rod 5 can adjust the angle of the meshing spur gear 6. When the adjustment position is determined, the adjusting rod 5 rotates under the action of the torsion spring, and a number of tooth pieces 8 are transferred into the corresponding limiting grooves 308 on the lower side of the balancing seat 301, so that the position of the balancing seat 301 after adjustment is immediately determined, and the limiting block 9 falls into the corresponding groove of the positioning groove block 10, so that the front and rear positions of the adjusting rod 5 are determined. Through the design of the adjusting rod 5 and the tooth pieces 8, the operator can quickly and easily adjust the spacing between the rollers 2. Compared with the traditional adjustment method, the adjustment time is significantly reduced, so that the production line can operate more efficiently. After adjustment, the tooth pieces 8 can be immediately locked in the limiting grooves 308 to ensure that the spacing of the rollers 2 is maintained at the desired position to avoid position changes due to vibration or other factors. The precise design of the adjustment mechanism 4 ensures that each adjustment can achieve a consistent spacing, thereby ensuring the consistency of the drying effect and the quality of the cardboard.
