Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, and more specifically, to a paper dust removal and humidity pretreatment device. Background Technology

[0002] Paper is a thin, sheet-like fibrous product made primarily from plant fibers through multiple processes including pulping, conditioning, papermaking, and processing. The production process typically begins by separating plant fiber raw materials such as wood, bamboo, and straw into individual fibers using chemical or mechanical methods to form pulp. This pulp then undergoes screening, purification, and beating to adjust fiber properties. Next, a paper machine evenly distributes the pulp onto a special wire mesh, allowing the fibers to interweave and bond, resulting in initial dehydration and shaping. Finally, pressing and drying processes remove moisture and enhance paper strength. Paper is characterized by its thinness, flexibility, writability, printability, and relatively low cost, making it widely used in writing, printing, packaging, hygiene products, and many other fields. It is an indispensable material in the development of human civilization. During paper processing, the original surface of the paper may contain dust or be damp, directly affecting its subsequent performance. Therefore, surface pretreatment is necessary to optimize its properties.

[0003] A search revealed that Chinese patent application number CN202323285844.9 discloses a paper surface treatment device, including a support, a transmission mechanism, a cleaning mechanism, a flattening mechanism, and a limiting mechanism. The transmission mechanism is provided on one side surface of the support, a fixing plate is fixedly connected to the upper surface of the support, the cleaning mechanism is provided on one side surface of the fixing plate, the flattening mechanism is provided on one side surface of the fixing plate, and the limiting mechanism is provided on the upper surface of the support.

[0004] While the aforementioned patent describes a method for cleaning thicker paper by using brushes to remove dust from its surface during transport, allowing dust to pass through a fixed groove into a filter chamber via an air pump, where it is filtered and stored in a storage bin, and the gas exiting the air pump through the filter chamber, thus cleaning the surface of thicker paper and driving the rollers to rotate, effectively flattening the paper and preventing wrinkles, the following shortcomings still exist in its application: 1. The device's limit plate adjustment requires individual adjustments in turn, which is cumbersome; 2. The filter in the filter chamber gradually becomes clogged during dust filtration, affecting the dust collection effect and making cleaning and replacement difficult. Furthermore, the flattening structure of the device is not easily adjustable to accommodate paper of different thicknesses.

[0005] Therefore, there is an urgent need for a paper dust removal and moisture pretreatment device to solve the above problems. Utility Model Content

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] A paper dust removal and moisture pretreatment device includes a work frame, with symmetrically distributed mounting plates fixedly connected to the top wall of the work frame, and symmetrically distributed fixing plates also fixedly connected to the top wall of the work frame. Symmetrically distributed drive shafts are rotatably connected to the outer wall of the work frame, and a conveyor belt is provided on the outer wall of the drive shaft. The device also includes:

[0009] A synchronous adjustment assembly includes a fixed rod fixedly connected between symmetrical mounting plates, a symmetrically distributed slider slidably connected to the outer wall of the fixed rod, a limit plate rotatably connected to the outer wall of the slider, a linkage frame fixedly connected to the outer wall of the slider, a bidirectional screw threadedly connected to the outer wall of the linkage frame, and a symmetrically distributed side frame rotatably connected to the outer wall of the bidirectional screw, and the side frame is fixedly connected to the working frame.

[0014] As a preferred technical solution of this application, the detachable component includes a filter chamber fixedly connected to the outer wall of the exhaust pipe A, and the filter chamber is fixedly connected to the working frame. The inner wall of the filter chamber is provided with symmetrically distributed sliding grooves, and a honeycomb filter plate is slidably connected to the inner wall of the sliding groove. The outer wall of the honeycomb filter plate is provided with symmetrically distributed slots, and the outer wall of the filter chamber is threadedly connected with symmetrically distributed side sealing covers, and the outer wall of the side sealing covers abuts against the outer wall of the slots.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the scheme of this application:

[0021] 1. By setting up a synchronous adjustment component, the adjustment of the limit plate no longer requires separate operation in turn.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0035] like Figure 1-9As shown, the paper dust removal and moisture pretreatment equipment proposed in this embodiment includes a work frame 1, with symmetrically distributed mounting plates 8 fixedly connected to the top wall of the work frame 1, and symmetrically distributed fixing plates 17 also fixedly connected to the top wall of the work frame 1. Symmetrically distributed drive shafts 7 are rotatably connected to the outer wall of the work frame 1, and a conveyor belt 2 is provided on the outer wall of the drive shaft 7. The equipment also includes:

[0036] The synchronous adjustment assembly includes a fixed rod 15 fixedly connected between symmetrical mounting plates 8. The outer wall of the fixed rod 15 is slidably connected to symmetrically distributed sliders 14. The outer wall of the sliders 14 is rotatably connected to a limit plate 16. The outer wall of the sliders 14 is fixedly connected to a linkage frame 13. The outer wall of the linkage frame 13 is threadedly connected to a bidirectional screw 10. The outer wall of the bidirectional screw 10 is rotatably connected to symmetrically distributed side frames 9, and the side frames 9 are fixedly connected to the work frame 1. When the bidirectional screw 10 rotates, the linkage frame 13 will drive the sliders 14 to slide on the fixed rod 15, thereby causing the limit plate 16 to move synchronously, thus completing the synchronous adjustment of the paper feeding width.

[0037] An extension frame 24 is fixedly connected to the outer wall of the work frame 1. An air pump 25 is fixedly connected to the top wall of the extension frame 24. An exhaust pipe A26 is fixedly connected to the air inlet of the air pump 25.

[0038] An adaptive component is mounted on the outer wall of the fixed plate 17;

[0039] A removable component is located on the outer wall of exhaust pipe A26.

[0040] like Figure 4-5 As shown, in a preferred embodiment, based on the above method, the adaptive component further includes a fixed column 18 fixedly connected to the outer wall of the fixed plate 17, a lifting block 34 slidably connected to the outer wall of the fixed column 18, a strong spring 20 sleeved on the outer wall of the fixed column 18, and the strong spring 20 fixedly connected to the lifting block 34. The end of the strong spring 20 away from the lifting block 34 is fixedly connected to the fixed plate 17. A heating shaft 21 is rotatably connected between the symmetrical lifting blocks 34. A roller 22 is fixedly connected to the outer wall of the heating shaft 21. During the paper conveying on the conveyor belt 2, the brush 19 on the outer wall of the symmetrical fixed plate 17 will perform preliminary cleaning on the paper surface. At the same time, the heating shaft 21 drives the roller 22 to rotate. Under the action of the strong spring 20, the roller 22 can adapt to paper of different thicknesses, flatten the paper and perform heating pretreatment, and adjust the paper humidity.

[0041] like Figure 7-9As shown, in a preferred embodiment, based on the above method, the detachable component further includes a filter chamber 27 fixedly connected to the outer wall of the exhaust pipe A26, and the filter chamber 27 is fixedly connected to the work frame 1. The inner wall of the filter chamber 27 is provided with symmetrically distributed sliding grooves 32, and a honeycomb filter plate 30 is slidably connected to the inner wall of the sliding grooves 32. The outer wall of the honeycomb filter plate 30 is provided with symmetrically distributed slots 33, and the outer wall of the filter chamber 27 is threadedly connected with symmetrically distributed side sealing covers 29, and the outer wall of the side sealing cover 29 abuts against the outer wall of the slot 33. When cleaning the honeycomb filter plate 30, it is only necessary to rotate the side sealing cover 29 to move the side sealing cover 29 out of the slot 33, and then slide the honeycomb filter plate 30 out of the sliding groove 32.

[0042] like Figure 7 As shown, in a preferred embodiment, based on the above method, a storage box 31 is further threadedly connected to the outer wall of the filter chamber 27, and an exhaust pipe B28 is fixedly connected to the outer wall of the filter chamber 27. A fixing box 23 is fixedly connected to the end of the exhaust pipe B28 away from the filter chamber 27, and the fixing box 23 is fixedly connected to the work frame 1. When the air pump 25 is started, the dust on the paper is sucked into the filter chamber 27 through the fixing box 23 and the exhaust pipe B28. After the air enters the filter chamber 27, it is first filtered by the honeycomb filter plate 30. The dust is intercepted on the honeycomb filter plate 30, and some of the dust falls into the storage box 31. The filtered air is finally discharged through the exhaust pipe A26 and the air outlet of the air pump 25.

[0043] like Figure 3 As shown, in a preferred embodiment, based on the above method, a turntable 11 is fixedly connected to the outer wall of the bidirectional screw 10, and the turntable 11 is rotatably connected to the side frame 9. A handle 12 is fixedly connected to the outer wall of the turntable 11. To adjust the width of the paper feed, the handle 12 is rotated, and the handle 12 drives the turntable 11 to rotate, which in turn drives the bidirectional screw 10 to rotate.

[0044] like Figure 1-2 As shown, in a preferred embodiment, based on the above method, a drive motor 3 is fixedly connected to the outer wall of the work frame 1, and a drive pulley 4 is fixedly connected to the output end of the drive motor 3. The drive pulley 4 is connected to a driven pulley 6 through the belt body 5, and the driven pulley 6 is fixedly connected to the transmission shaft 7. When the equipment starts the drive motor 3, its output end drives the drive pulley 4 to rotate. The drive pulley 4 drives the driven pulley 6 to rotate through the belt body 5, thereby causing the transmission shaft 7 to rotate. The transmission shaft 7 drives the conveyor belt 2 to rotate, thereby realizing the paper conveying.

[0045] like Figure 4 As shown, in a preferred embodiment, based on the above method, a brush 19 is further fixedly connected to the outer wall of the symmetrical fixing plate 17, and the brush 19 cleans the dust on the paper.

[0046] Specifically, when using this paper dust removal and humidity pretreatment equipment: to adjust the width of the paper conveying, turn the handle 12. The handle 12 drives the turntable 11 to rotate, and the turntable 11 drives the bidirectional screw 10 to rotate. Since the bidirectional screw 10 is threadedly connected to the linkage frame 13, when the bidirectional screw 10 rotates, the linkage frame 13 will drive the slider 14 to slide on the fixed rod 15, thereby causing the limiting plate 16 to move synchronously, completing the synchronous adjustment of the paper conveying width. During the paper conveying on the conveyor belt 2, the brush 19 on the outer wall of the symmetrical fixed plate 17 will perform preliminary cleaning on the paper surface. At the same time, the heated rotating shaft 21 drives the roller 22 to rotate, and the roller 22 is powered by a strong spring. Under the action of 20, it can adapt to paper of different thicknesses, flatten the paper and pre-treat it with heat, and adjust the paper humidity; when the air pump 25 is started, the dust on the paper is sucked into the filter chamber 27 through the fixed box 23 and the exhaust pipe B28. After the air enters the filter chamber 27, it is first filtered by the honeycomb filter plate 30. The dust is intercepted on the honeycomb filter plate 30, and some of the dust falls into the storage box 31. The filtered air is finally discharged through the exhaust pipe A26 and the air outlet of the air pump 25. When cleaning the honeycomb filter plate 30, you only need to rotate the side sealing cover 29 to move the side sealing cover 29 out of the slot 33, and then slide the honeycomb filter plate 30 out of the slide groove 32.

[0047] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
