Description

Technical Field

[0001] The present invention relates to the technical field of fruit bag paper production, and specifically to an antibacterial fruit bag paper production device and its process. Background Art

[0002] As a key protective material in fruit cultivation, fruit bag paper is widely used in the bagging cultivation of economic crops such as apples and grapes, which can effectively isolate pests and diseases, reduce pesticide residues, and improve the appearance of fruits. Fruit bag paper is mostly made of wood pulp fibers through a papermaking process. In the prior art, antibacterial fruit bag paper is mostly achieved through an impregnation method or a surface coating process, that is, a treatment liquid containing chemical antibacterial agents such as silver ions and quaternary ammonium salts is added after the paper is formed. Before the fruit bag paper is formed, a papermaking production device is used to form the paper, which is convenient for subsequent slitting and the like.

[0003] Usually, when forming and papermaking, to improve the quality of the finished product, the pulp will be simply filtered, or filtration is used to separate fine paper and coarse paper. For example, in a waste paper treatment device disclosed in the prior patent publication number CN115029950B, it includes a base, a coarse pulp conveyor belt, a pulp hanging coarse sand screen, a drainage shell, a pulp hanging fine sand screen, a first motor, a heating roller, a dehydration roller, a fine pulp conveyor belt, a first film winding roller, a second film winding roller, a sixth motor, and a third motor; the slurry is poured into the pulp hanging coarse sand screen, and the slurry in the pulp hanging coarse sand screen flows through the pulp outlet on it and falls onto the coarse pulp conveyor belt; after the slurry falling from the pulp hanging coarse sand screen falls onto the coarse pulp conveyor belt, most of the water in the slurry and part of the slurry will seep down into the drainage shell under the pulp hanging coarse sand screen, and the remaining water and slurry are driven by the coarse pulp conveyor belt to move backward; most of the water flowing into the drainage shell will flow into the first water storage tank through the filter holes, and the remaining slurry and a small amount of water will flow downward along the drainage shell, and after passing through the side flow channels on both sides, it will flow into the pulp hanging fine sand screen and fall onto the fine pulp conveyor belt from the pulp outlet under the pulp hanging fine sand screen.

[0004] However, in the above papermaking operation, the flow of the pulp adopts physical penetration and cannot be dynamically adjusted. It is not convenient to control the pulp concentration of the coarse paper and the fine paper. The pulp concentration is unstable during papermaking, which will affect the uniformity of the finished products of both the coarse paper and the fine paper at the same time. This forced production mode of distinction limits the flexibility of the product, cannot uniformly regulate the paper properties according to requirements, and results in high equipment energy consumption and high maintenance costs. In view of the above problems, an antibacterial fruit bag paper production device and its process are proposed. Summary of the Invention

[0049] Among them, the feeding mechanism 4 includes a feeding tray 41 and a filtering tray 42. A base 43 for supporting the sliding of the feeding tray 41 is provided at the bottom of the feeding tray 41.

[0052] The slurry is sent to the slurry storage tank 51 through the slurry guiding hopper 52 for storage, and then can flow out from the slurry discharge box 53 into the mesh belt paper feeding mechanism 2 and the blanket paper feeding mechanism 3 for slurry spreading and conveying. Excess water can be squeezed out during the conveying and collected in the collection mechanism 8;

[0053] The formed original paper of the antibacterial fruit bag paper can be sent to the drying mechanism 6 for drying, and then output from the discharging mechanism 7 and sent to the next processing point for slitting and die pressing.

[0054] Nano silver antibacterial agent and chitosan solution are directly added in the raw material mixing stage, and the antibacterial agent and the fiber are evenly dispersed and in-situ compounded through the three-level synergistic effect of the filter plate 42, the feed plate 41 and the pulp guide bucket 52.

The anti-aging agent directionally migrates to the surface of the paper at the gradient temperature, and the weather resistance is increased by 2 times.

[0055] See also Figures 4-7 The base 43 includes two groups of seat bodies 431, and the bottom of the feeding tray 41 is slidably connected to the seat body 431 through a slider; a support frame 432 is provided on the side away from the two groups of seat bodies 431, and the top of the support frame 432 is connected to the wave guide rail 433; specifically, the feeding tray 41 can slide on the seat body 431 to promote the flow of slurry on the feeding tray 41;

[0056] The toggle member 44 includes a motor box 441 and a movable seat 444. The bottom of the feed tray 41 is connected to the motor box 441 through a mounting rod 47. The mounting rod 47 passes through the support frame 432. A motor is installed in the motor box 441. An eccentric block 442 is installed on the motor shaft at the power output end of the motor. The eccentric block 442 is rotatably connected to a connecting rod 443 at one end away from the motor shaft. The connecting rod 443 is rotatably connected to a movable seat 444 at one end away from the eccentric block 442. One side of the movable seat 444 is connected to a pulling member 45. Specifically, the motor in the motor box 441 can drive the eccentric block 442 to rotate around the axis of the motor shaft, and the movable seat 444 can be pulled to move through the connecting rod 443. Through the connection of the pulling member 45, the filter plate 42 can be pulled to move back and forth.

[0057] The seat body 431 is provided with a slide groove A434 for the motor box 441 to slide and a slide groove B437 for the moving seat 444 to slide. Both sides of the motor box 441 are connected with a through rod 435 that slides with the seat body 431. The through rod 435 is sleeved with a first spring 436 arranged in the slide groove A434. The slide groove B437 is provided with a sleeve rod 438 that slides with the moving seat 444. The sleeve rod 438 is sleeved with a second spring 439. One set of the through rods 435 can extend into the sleeve rod 438.

[0058] When the moving seat 444 moves, it slides on the sleeve rod 438 and repeatedly presses the second spring 439. At the same time, during the movement of the moving seat 444, since the through rods 435 are connected to both sides of the motor box 441, the motor box 441 can slide in the chute A434 and repeatedly press the first springs 436 on both sides under the drive of the reverse force of the mechanisms such as its own vibration and the connecting rod 443. Driven by the eccentric block 442 and the connecting rod 443, both the feeding tray 41 and the filtering tray 42 move reciprocally. At the same time, under the action of the first spring 436 and the second spring 439, they move reciprocally irregularly, improving the vibration feeding effect.

[0059] Please refer to Figures 4-6 , the pulling member 45 includes a support frame 451 connected to the moving seat 444. A floating block 452 is slidably connected in the lifting groove at the top of the support frame 451. A pull rod 453 is slidably connected in the floating block 452. One end of the pull rod 453 is connected to the filtering tray 42, and the other end is connected to a limiting plate. Third springs 454 sleeved on the pull rod 453 are provided on both sides of the floating block 452; the shock-absorbing member 46 includes a wheel seat 461.

[0060] Specifically, when the moving seat 444 moves, it will pull the filtering tray 42 to move. At the same time, when the guide wheel 463 rolls on the wave guide 433, it will repeatedly press the fourth spring 462, and the filtering tray 42 will vibrate. During the vibration, the floating block 452 slides in the lifting groove in the support frame 451, the pull rod 453 slides in the floating block 452, and presses the third spring 454. The filtering tray 42 will vibrate irregularly, introducing a dynamic disturbance mechanism, which can maintain the fluidity of the slurry in the case of extremely high solid content.

[0061] Furthermore, a plurality of slurry delivery pipes are provided in the slurry outlet box 53, and concentration sensors 54 are installed on the corresponding slurry delivery pipes. An electric telescopic rod 55 is installed at the convex part on one side of the slurry outlet box 53. The movable end of the electric telescopic rod 55 extends into the slurry outlet box 53 and is connected to a sealing plate for blocking the outlet of the slurry delivery pipe; a support plate 57 is installed on the top of the slurry storage tank 51, and a liquid level detector 58 is installed on the support plate 57.

[0062] The liquid level detector 58 can detect the liquid level height in the slurry storage tank 51, which is beneficial for other control devices to control the slurry delivery amount to the filtering tray 42.

[0063] A plurality of electric telescopic rods 55 are provided. The plurality of electric telescopic rods 55 uniformly control a group of sealing plates to block the discharging part of the slurry feeding pipe and control the flow. The concentration sensor 54 performs concentration detection, facilitating concentration control and enabling the slurry feeding pipe to stably output slurry with a moderate concentration.

[0064] Please refer to Figure 8 and Figure 9 As shown in FIGS. and, a mixing member 56 is further installed on the slurry storage tank 51. The mixing member 56 includes a mixing frame 561 rotatably installed in the slurry storage tank 51. One end of the mixing frame 561 is connected to a first synchronous pulley A 562 through a connecting shaft. The shaft ends of a group of the second conveying rollers 31 at the top are connected to a second synchronous pulley A 563. The first synchronous pulley A 562 and the second synchronous pulley A 563 are drivingly connected through a synchronous belt A.

[0065] Specifically, during the rotation of the second conveying roller 31, through the transmission of the second synchronous pulley A 563 and the synchronous belt A, the first synchronous pulley A 562 is driven to rotate, enabling the mixing member 56 to perform a mixing operation and making the slurry in the slurry storage tank 51 mix evenly.

[0066] Please refer to Figure 1 and Figure 3 As shown in FIGS. and, the mesh belt paper feeding mechanism 2 includes a plurality of first conveying rollers 21 and a mesh belt 22 installed on the first conveying rollers 21; the blanket paper feeding mechanism 3 includes a plurality of second conveying rollers 31 and a papermaking blanket 32 installed on the second conveying rollers 31; the mesh belt 22 is placed at the bottom of the papermaking blanket 32; there is a slurry feeding area between a group of second conveying rollers 31 located at the top and close to the feeding mechanism 4 and a group of first conveying rollers 21 located at the top and close to the feeding mechanism 4. Another group of first conveying rollers 21 for tensioning the mesh belt 22 is provided at the bottom of the group of first conveying rollers 21 close to the slurry feeding area, and the remaining first conveying rollers 21 are arranged on the top of the collecting mechanism 8; the second conveying rollers 31 are sequentially arranged in the direction close to the drying mechanism 6.

[0067] The slurry enters the slurry feeding area through the feeding mechanism 4. The mesh belt 22 and the papermaking blanket 32 run synchronously, clamping and conveying the slurry forward. The pore structure of the mesh belt 22 allows the initial seepage of water, realizing the pre-dehydration of the slurry. At the same time, the flexible surface of the papermaking blanket 32 assists in the uniform distribution of the slurry. The flexible surface of the papermaking blanket 32 can compensate for the thickness fluctuation of the slurry, avoiding local accumulation or being too thin, and improving the uniformity of the formed paper. The mesh belt 22 extends to the top of the collecting mechanism 8 after being tensioned, completing the continuous auxiliary conveying of the slurry from the wet state to the semi-dry state. The papermaking blanket 32 carries the slurry into the subsequent drying stage, shortening the exposure time of the wet paper web and reducing the risk of rewetting before drying.

[0068] Please refer to Figure 3 and Figure 11The collecting mechanism 8 comprises a collecting pool 81, a cleaning member 82 arranged on the top of the collecting pool 81 and an output pipe 83 installed on one side of the collecting pool 81; wherein the cleaning member 82 comprises two groups of driving rollers 821 rotatably mounted on the frame 1, cleaning belts 822 are installed on the two groups of driving rollers 821, the surfaces of the cleaning belts 822 are connected with a plurality of cleaning scrapers 823, and the side of the cleaning scrapers 823 away from the cleaning belts 822 is connected with a brush; the shaft ends of a group of the first conveying rollers 21 arranged near the cleaning member 82 are connected with the second synchronous wheel B825, and the ends of one group of the driving rollers 821 are connected with the first synchronous wheel B824, and the first synchronous wheel B824 and the second synchronous wheel B825 are connected through the transmission of the synchronous belt B;

[0069] Specifically, when the mesh belt 22 is running, the driving roller 821 of the cleaning member 82 is driven to rotate by the synchronous belt B, and the cleaning scraper 823 presses against the surface of the mesh belt 22 at a certain angle to scrape off the adhered pulp blocks or fiber clumps. The scraped waste moves with the cleaning belt 822 to the top of the collection pool 81, and is separated from the cleaning belt 822 due to gravity or vibration and falls into the pool for centralized treatment, thereby cleaning the mesh belt 22 and extending the cleaning cycle and service life of the mesh belt 22.
