[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1-11 As shown, the technical solution adopted by the present invention is as follows: a batching process for producing paper pulp, comprising the following steps: S1. Tilt the lifting assembly of the mixing and conveying mechanism to the left, and add materials to the second conveyor belt 29 of the mixing and conveying mechanism.

[0023] S2. The second conveyor belt 29 is conveyed to the right, and the materials are gathered on the left side of the jacking assembly. The mixing roller 11 in the mixing and conveying mechanism mixes the materials evenly.

[0024] S3. The lifting assembly is tilted to the right, and the second conveyor belt 29 drives the material to be conveyed to the right.

[0025] The mixing and conveying mechanism also includes two side panels 1, with a second conveyor belt 29 disposed between the two side panels 1. Specifically, two first transmission rollers 23 are rotatably mounted between the two side panels 1. A first motor 3 is fixedly mounted on the side panels 1, and the output shaft of the first motor 3 is fixedly connected to one of the first transmission rollers 23. The second conveyor belt 29 is wound between the two first transmission rollers 23.

[0026] One end of the jacking assembly is rotatably mounted on the side plate 1 , and the other end of the jacking assembly jacks up the corresponding portion on the upper side of the second conveyor belt 29 .

[0027] In this embodiment, there are two lifting assemblies, and the two lifting assemblies are spaced apart along the conveying direction of the second conveyor belt 29 .

[0028] The lifting assembly includes a rotating rod 25, a sliding rod 27, and a second drive roller 26. One end of the rotating rod 25 is rotatably mounted on the side panel 1. A second motor 4 is mounted on the side panel 1 to drive the rotating rod 25. A sliding groove is defined at the other end of the rotating rod 25. One end of the sliding rod 27 slides within the groove. A spring 28 is positioned within the groove. One end of the spring 28 is fixedly connected to the sliding rod 27, and the other end of the spring 28 is fixedly connected to the end wall of the groove. The end of the sliding rod 27, distal from the spring 28, is rotatably connected to the second drive roller 26. The second drive roller 26 is coupled to a second conveyor belt 29.

[0029] Mixing rollers 11 are installed on both sides of the jacking assembly and are rotatably mounted on the side panels 1. The mixing rollers 11 include mounting plates and thin rods. The mounting plates are rotatably connected to the side panels 1, and multiple thin rods are mounted on the rotating plates. The thin rods are perpendicular to the conveying direction of the second conveyor belt 29.

[0030] The mixing rollers 11 limit the second conveyor belt 29 , and the second conveyor belt 29 between the two mixing rollers 11 is lifted upward by the lifting assembly, and under the action of the lifting assembly, the second conveyor belt 29 is in a tensioned state. The second conveyor belt 29 is bent at the mixing rollers 11 .

[0031] The jacking assembly tilts to the left, and the mixing roller 11 on the left side of the jacking assembly bends the second conveyor belt 29 at an acute angle. The mixing roller 11 on the right side of the jacking assembly bends the second conveyor belt 29 at an obtuse angle.

[0032] When the material moves to the right to the left side of the jacking assembly, the jacking assembly is tilted to the left, so the material cannot pass over the upper end of the jacking assembly and continue to be transported forward. The material is gathered on the left side of the jacking assembly and is mixed evenly under the action of the mixing roller 11. After that, the jacking assembly is tilted to the right, and the material can pass over the jacking assembly and continue to be transported to the right.

[0033] A feeding mechanism is provided on one side of the mixing and conveying mechanism for quantitatively feeding materials onto the mixing and conveying mechanism. The discharge end of the feeding mechanism is located above the second conveyor belt 29.

[0034] The unloading mechanism includes a first conveyor belt 5, a connecting plate 7, and a vibrating assembly. A support leg is mounted at the lower end of the connecting plate 7. There are two connecting plates 7, with the first conveyor belt 5 mounted between them. Two support rollers are rotatably mounted between the two connecting plates 7, with the first conveyor belt 5 wound between them.

[0035] A hopper 6 is fixedly connected between the two connecting plates 7. Materials are added to the first conveyor belt 5 through the hopper 6.

[0036] The lower end of the hopper 6 is slidably provided with a baffle 20 that blocks the lower end of the hopper 6. The hopper 6 is provided with an electric push rod 21 that drives the baffle 20 to move. The electric push rod 21 drives the baffle 20 to move, thereby opening or closing the lower end of the hopper 6.

[0037] A plurality of partitions 8 are installed at intervals along the conveying direction on the first conveyor belt 5. Two adjacent partitions 8, the first conveyor belt 5 and the connecting plate 7 form a material holding cavity.

[0038] The hopper 6 is provided with a scraper 19 which cooperates with the partition 8. The material flows into the material holding cavity between the two partitions 8 on the first conveyor belt 5 through the hopper 6. As the first conveyor belt 5 conveys, the scraper 19 scrapes off the excess material in the material holding cavity, thereby achieving quantitative conveying.

[0039] A housing 10 is fixedly mounted on the outside of each connecting plate 7. The two housings 10 are symmetrically arranged. A first sprocket 16 and a second sprocket 18 are rotatably mounted within each housing 10. A chain 15 is wound between the first and second sprockets 16, 18. The first and second sprockets 16, 18 are each fixedly connected to a corresponding support roller. A groove is provided in the housing 10. The upper side of the chain 15 is in a tensioned state, while the lower side of the chain 15 is in a relaxed state. The connecting plates 7 have grooves extending into the housing 10, and the lower side of the chain 15 sags into the groove under its own weight.

[0040] The chain 15 is fixedly connected to the first conveyor belt 5, and the chain 15 drives the first conveyor belt 5 to move. As the chain 15 droops into the groove, a corresponding portion of the first conveyor belt 5 droops to form a drooping portion 22.

[0041] A support block 14 is installed in the housing 10 , and the support block 14 serves to limit the position of the chain 15 .

[0042] like Figure 3 、 Figure 4As shown, a third motor 9 is fixedly mounted on the housing 10 to drive the second sprocket 18. The third motor 9 drives the second sprocket 18 to rotate, causing the upper side of the chain 15 to move rightward. The second sprocket 18, via the upper side of the chain 15, drives the first sprocket 16 to rotate. The first sprocket 16 drives the lower side of the chain 15 to move leftward. The lower chain 15 passes through the groove and moves below the support block 14. The support block 14 acts as a limiter for the chain 15, ensuring that the chain 15 remains straight between the first sprocket 16 and the groove.

[0043] The vibration assembly includes a connecting rod 13 and a fourth motor 12. The fourth motor 12 is mounted on the connecting plate 7, with one end of the connecting rod 13 connected to the output shaft of the fourth motor 12. The connecting rod 13 rotates upward, lifting the drooping portion 22. When the connecting rod 13 disengages from the drooping portion 22, the drooping portion 22 rapidly drops under its own weight, causing the first conveyor belt 5 to vibrate and shake off any material adhering to the first conveyor belt 5.

[0044] The connecting plate 7 is provided with a notch 17 that cooperates with the connecting rod 13, and the notch 17 passes through the housing 10. The connecting rod 13 can be rotated to the outside of the housing 10 and quickly separated from the first conveyor belt 5.

[0045] A feeding port 2 is provided above the left end of the second conveyor belt 29 .

[0046] In this embodiment, papermaking pulp is primarily made from hardwood chips, maple chips, and pine chips. Mixed hardwood chips and maple chips are added to a second conveyor belt 29 through a feed port 2. Pine chips are added to the second conveyor belt 29 through a feed mechanism. The feed mechanism allows different amounts of pine chips to be fed to the second conveyor belt 29, thereby producing different types of paper. The hardwood chips, maple chips, and pine chips are evenly mixed on the second conveyor belt 29 and then conveyed to the right end.

[0047] Working principle: Initially, the lifting assembly tilts to the left, and the mixing and conveying mechanism is in a mixing state. The distorted portion of the second conveyor belt 29 on the left side of the lifting assembly is defined as a corner 24.

[0048] The mixed hardwood chips and maple chips are added to the second conveyor belt 29 through the discharge port 2, and a fixed amount of pine chips are transported to the second conveyor belt 29 through the discharge mechanism.

[0049] In the process of conveying the pine wood chips to the second conveyor belt 29 through the unloading mechanism, pine wood chips are added to the hopper 6, and the electric push rod 21 is started to open the lower end of the hopper 6, and the pine wood chips fall into the material holding cavity between two adjacent partitions 8 on the first conveyor belt 5.

[0050] Start the third motor 9, and the chain 15 moves, which drives the first conveyor belt 5 to move. When the pine chips pass through the scraper 19, the scraper 19 flattens the upper ends of the pine chips between the two adjacent partitions 8, thereby quantifying the pine chips between the two adjacent partitions 8. Afterwards, as the first conveyor belt 5 moves, the pine chips on the first conveyor belt 5 fall onto the second conveyor belt 29. Since the amount of pine chips between the two adjacent partitions 8 is fixed, the amount of pine chips in a single material chamber is fixed. If the pine chips in a single material chamber are defined as one portion, then by allowing different numbers of pine chips to fall onto the second conveyor belt 29, the amount of pine chips added can be controlled, achieving quantitative unloading of pine chips. The amount of pine chips added can also be easily adjusted to suit the production of different types of paper.

[0051] The fourth motor 12 is started, and the connecting rod 13 rotates, causing the connecting rod 13 to rotate upward and contact the sagging portion 22 of the first conveyor belt 5. When the connecting rod 13 contacts the first conveyor belt 5, it strikes the first conveyor belt 5, causing it to vibrate, thereby facilitating the removal of pine wood chips adhered to the first conveyor belt 5. As the connecting rod 13 continues to rotate, the connecting rod 13 gradually lifts the sagging portion 22 on the first conveyor belt 5 upward. Thereafter, as the connecting rod 13 continues to rotate, the connecting rod 13 passes through the notch 17 and rotates to the outside of the housing 10, thereby rapidly disengaging the connecting rod 13 from the first conveyor belt 5. The first conveyor belt 5 and the chain 15 fall into the groove under their own gravity, thereby causing the first conveyor belt 5 to vibrate, shaking off the pine wood chips adhered to the first conveyor belt 5, so that all the pine wood chips fall onto the first conveyor belt 5, facilitating the precise unloading of the pine wood chips.

[0052] After the broadleaf wood chips, maple wood chips and pine wood chips are added, the first motor 3 is started to move the upper side of the second conveyor belt 29 to the right.

[0053] When the broadleaf wood chips, maple wood chips and pine wood chips move to the left side of the jacking assembly, the jacking assembly is tilted to the left, so that the broadleaf wood chips, maple wood chips and pine wood chips cannot pass over the upper end of the jacking assembly and gather at the corner 24. The mixing roller 11 is rotated to mix the broadleaf wood chips, maple wood chips and pine wood chips at the corner 24 so that the broadleaf wood chips, maple wood chips and pine wood chips are evenly mixed.

[0054] It should be noted that the broadleaf wood chips, maple wood chips and pine wood chips all fall to the left side of the left jacking component, and the broadleaf wood chips, maple wood chips and pine wood chips are mainly mixed at the corner 24 of the left jacking component. If there are broadleaf wood chips, maple wood chips and pine wood chips passing over the upper end of the left jacking component, then the broadleaf wood chips, maple wood chips and pine wood chips that pass over the upper end of the left jacking component will gather at the corner 24 of the right jacking component, and the mixing roller 11 at the corner 24 of the right jacking component mixes the broadleaf wood chips, maple wood chips and pine wood chips.

[0055] The arrangement of the two jacking components can also perform two mixing operations on the broadleaf wood chips, maple wood chips and pine wood chips, which is conducive to making the broadleaf wood chips, maple wood chips and pine wood chips mixed more evenly.

[0056] After the broadleaf wood chips, maple wood chips and pine wood chips are evenly mixed, the second motor 4 is started to rotate the jacking assembly to the right, thereby tilting the jacking assembly to the right. Figure 11 Afterwards, as the upper side of the second conveyor belt 29 moves rightward, the hardwood chips, maple chips and pine chips mixed evenly on the second conveyor belt 29 move rightward along with the second conveyor belt 29.

[0057] After the conveying is completed, the second motor 4 is started again to rotate the jacking assembly to the left, so that the jacking assembly is tilted to the left by a certain angle so that the jacking assembly returns to the initial state and is ready for the next mixing.

[0058] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
