Description

Technical Field

[0001] The utility model belongs to the technical field of papermaking transportation, in particular to a papermaking transportation device. Background Art

[0002] At present, in the papermaking industry, paper transportation is one of the important links in the production process. Traditional conveyors mostly adopt belt or chain structures, and realize continuous paper transportation through motor drive. However, these traditional conveyors have problems such as low efficiency and poor stability in actual use, especially their performance on high-speed production lines is not satisfactory, which seriously affects the production capacity and quality control of the entire production line. In order to improve the efficiency and stability of paper transportation, the industry has adopted several different improvement measures. Among them, the more common ones are: (1) increasing the friction coefficient of the conveyor belt to reduce the phenomenon of paper sliding; (2) improving the power distribution of the drive system to ensure the synchronization between each roller; (3) adding a guide device to help the paper enter the next process more smoothly. Although these methods have improved the transportation performance to a certain extent, they still cannot fully meet the needs of modern high-speed production lines. (4) In some cases, air flotation conveying technology is also used to reduce the contact between the paper and the conveying surface, thereby reducing the risk of wear and damage. However, this method is expensive and relatively complex to maintain. In summary, although the existing paper transportation technology has undergone a series of improvements, it still has many shortcomings when facing the high-precision and high-speed modern papermaking needs. The main problems were: low efficiency, difficulty adapting to the rapidly changing production pace; poor stability, which easily led to paper shifting and accumulation; difficult maintenance, which increased the company's operating costs; and the lack of inspection steps during the conveying process, resulting in defective paper and an inability to remove the defective paper. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned technical problems and provide a papermaking transportation device, which can detect paper and separate defective paper during transportation to improve the quality.

[0005] In this technical solution, the first conveyor assembly delivers paper to a conveyor belt, which is driven by a first motor to rotate and transport the paper. A detector inspects the paper and then controls a separation assembly to screen the paper. This process detects and separates defective paper during paper conveyance, improving the quality of the finished paper.

[0007] In this technical solution, a first motor drives a first conveyor belt via first and second conveyor rollers. While the first conveyor belt is transporting paper, a detector inspects the paper to identify defective paper and improve the quality of the finished paper.

[0009] In this technical solution, the paper stack is placed on the loading plate. The paper feeding unit transports the paper at the top of the stack one by one, and the lifting unit raises the paper stack on the loading plate. This prevents the height of the paper stack from decreasing as the number of papers on the stack decreases, preventing the paper feeding unit from being unable to operate. This improves work efficiency.

[0013] In this technical solution, the first exhaust fan uses a suction nozzle to attract paper to the bottom of the shroud, separating the paper from the paper below it and preventing multiple sheets from being transported together. The third motor drives the friction output wheel via the first rotating roller to rotate, and the friction output wheel transports the paper through the friction force of the wheel surface. The shroud prevents the first exhaust fan from reducing the influence of external airflow when operating through the suction nozzle.

[0015] In the above technical solution, further, the second transport component includes a fourth motor, the fourth motor is fixedly arranged on the support frame, the output of the fourth motor is connected to the second transport belt, the first transport belt is arranged on the top of the support frame, and the third transport belt is arranged below the second transport belt. The third transport belt is arranged on the support frame corresponding to the first guide plate, the output of the third transport belt is connected to the fifth motor, and the fifth motor is fixedly arranged on the support frame.

[0016] In this technical solution, if qualified paper passes inspection and one side of the paper contacts the first driven roller, the first air nozzle activates suction and the second air nozzle activates air discharge, causing the paper to move upward a certain distance, preventing it from entering the first guide plate and landing on the second conveyor belt. If defective paper is present, the first air nozzle activates air discharge and the second air nozzle activates suction, causing it to move downward, enter the first guide plate, and land on the third conveyor belt. This separate transport of paper improves transportation efficiency and paper product quality.

[0017] The beneficial effects of the utility model are:

[0018] 1. By setting up a lifting unit, the loading plate can not only move up and down, but also bear the force evenly on both sides to avoid falling during transportation.

[0019] 2. By setting up a paper feeding unit, multiple sheets of paper are prevented from overlapping and being transported together. The third motor drives the friction output wheel to rotate through the first rotating roller, and the friction output wheel transports the paper through the friction force of the wheel surface.

[0020] 3. By setting the first air nozzle and the second air nozzle, the paper is transported separately, which improves the transportation efficiency and also improves the quality of paper products. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example 1:

[0035] This embodiment provides a papermaking transport device that detects paper and separates defective paper during transport, thereby improving quality.

[0036] In view of this, the utility model provides a papermaking conveyor, such as Figure 1 As shown, the paper conveyor comprises a support frame 1, a first conveying assembly 2, which is mounted on the support frame 1; a first motor 4, which is fixedly mounted on the support frame 1; a first conveyor belt 6, which is connected to the first motor 4; a detector 5, which is mounted directly above the conveyor belt; and a separation assembly 3, which is mounted on the support frame 1 on the side away from the conveyor assembly. The first conveyor assembly 2 conveys paper onto the conveyor belt, which rotates driven by the first motor 4. The first conveyor belt 6 transports the paper, and the detector 5 detects the paper and then controls the separation assembly 3 to screen the paper. During the paper conveying process, defective paper is detected and separated, thereby improving the quality of the finished paper.

[0037] like Figure 2 As shown, the output end of the first motor 4 is coaxially connected to a first conveyor roller, which is rotatably mounted within a mounting frame. The first conveyor roller 17 is connected to a second conveyor roller 18 via a first conveyor belt 6. The second conveyor roller 18 is rotatably mounted within a support frame 1, away from the first conveyor roller 17. A first mounting frame 7 is fixedly mounted on the support frame 1, and a detector 5 is fixedly mounted on the first mounting frame. The first motor 4 drives the first conveyor belt 6 to rotate via the first and second conveyor rollers. As the first conveyor belt 6 transports paper, the detector 5 inspects the paper to identify defective paper and improve the quality of the finished paper. The detector 5 is well-known and will not be described in detail.

[0038] like Figure 2 As shown, the first conveying assembly 2 includes a second mounting frame 14, which is symmetrically arranged inside the support frame 1. A first slide bar 12 is fixedly arranged inside the second mounting frame, and a carrier plate 11 is slidably arranged on the first slide bar 12. The output of the carrier plate 11 is connected to a lifting unit, and the lifting unit moves the carrier plate 11 up and down on the slide bar. A paper feeding unit is fixedly arranged on the second mounting frame 14, and the paper feeding unit transports the single sheets of paper stacked on the carrier plate 11 to the conveyor belt. The paper stack is placed on the carrier plate 11, and the paper feeding unit transports the paper at the top of the paper stack one by one. The lifting unit raises the paper stack on the carrier plate 11 to avoid the height of the paper stack itself decreasing when the paper on the paper stack decreases, and the paper feeding unit cannot work. This improves work efficiency.

[0039] like Figure 4 As shown, the lifting unit includes a first screw 13, which is threadedly connected to one side of the carrier 11. The other side of the carrier 11 is threadedly connected to a second screw 23. One end of the first screw 13 is rotatably mounted on the second mounting bracket 14, and the other end passes through the second mounting bracket 14 and is coaxially connected to a first gear 22. One end of the second screw 23 is rotatably mounted on the second mounting bracket 14, and the other end passes through the second mounting bracket 14 and is coaxially connected to a second gear 24. The first gear 22 is connected to the second gear 24 via a first chain 16. The first gear 22 is coaxially fixed with a second motor 15, which is fixed to the support frame 1. The second motor 15 drives the first gear 22 to rotate, and the first gear 22 drives the second gear 24 to rotate via a first sprocket. The first gear 22 and the second gear 24 rotate in the same direction, so that the first screw 13 and the second screw 23 act on the carrier 11 simultaneously. The carrier 11 can not only move up and down, but also has a uniform force on both sides, preventing it from falling during transportation.

[0040] like Figure 3As shown, the paper feeding unit includes a shroud 9, which is fixed to the top of the second mounting frame 14. A first exhaust fan 10 is fixedly installed inside the shroud 9. An air suction nozzle 19 is installed at the bottom of the first exhaust fan 10. A friction output wheel 21 is installed on one side of the first exhaust fan 10. The friction output wheel 21 is coaxially fixed to the first rotating roller 20. The friction output wheel 21 is linearly arranged on the first rotating roller 20 along the length direction of the first rotating roller 20. The first rotating roller 20 is rotatably installed on the inner wall of the shroud 9. The output of the first rotating roller 20 is connected to the third motor 8, which is fixed to the top of the shroud 9. The first exhaust fan 10 absorbs the paper at the bottom of the shroud 9 through the air suction nozzle 19, separates the paper from the paper below it, and prevents multiple sheets of paper from overlapping and being transported together. The third motor 8 drives the friction output wheel 21 to rotate through the first rotating roller 20. The friction output wheel 21 transports the paper through the friction force of the wheel surface. The air guide cover 9 prevents the first exhaust fan 10 from being affected by external airflow when the first exhaust fan 10 operates through the air suction nozzle 19 .

[0041] Example 2:

[0042] This embodiment provides a papermaking transport device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] like Figure 6 As shown, the separation component 3 includes an L-shaped mounting frame 25, which is fixedly arranged on the support frame 1. The top of the L-shaped mounting frame 25 is provided with a first air nozzle 29 with an opening downward, and the bottom of the L-shaped mounting frame 25 is provided with a second air nozzle 30 with an opening upward. A first driven roller 33 is rotatably arranged inside the L-shaped mounting frame 25, and a first guide plate is fixedly arranged on the side of the L-shaped mounting frame 25 away from the first conveyor belt 6. The first guide plate is connected to the second conveyor component, and the second conveyor component separately transports the defective paper separated from the qualified paper.

[0044] like Figure 5As shown, the second transport assembly includes a fourth motor 26, which is fixed to the support frame 1. The output of the fourth motor 26 is connected to a second transport belt 31. The first transport belt 6 is mounted on the top of the support frame 1. A third transport belt 32 is mounted below the second transport belt 31. The third transport belt 32 is mounted on the support frame 1 corresponding to the first guide plate 28. The output of the third transport belt 32 is connected to a fifth motor 27, which is fixed to the support frame 1. After the paper passes inspection, if the paper passes the inspection, as soon as one side of the paper contacts the first driven roller 33, the first air nozzle 29 activates suction and the second air nozzle 30 activates air discharge, causing the paper to move upward a certain distance to prevent it from entering the first guide plate, and the paper then lands on the second transport belt 31. If the paper is defective, as soon as one side of the paper contacts the first driven roller 33, the first air nozzle 29 activates air discharge and the second air nozzle 30 activates suction, causing the paper to move downward to enter the first guide plate, and then land on the third transport belt 32. This separate transport of paper improves transportation efficiency and paper product quality.

[0045] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
