Description

Technical Field

[0001] This invention relates to the field of dust removal technology in paper product processing, and more particularly to an air dust removal device for paper product manufacturing. Background Technology

[0002] Paper product manufacturing is a production activity that uses paper and paperboard as raw materials to produce paper products. It is a sub-sector of the manufacturing industry, covering container products such as corrugated boxes, paper boxes, and paper bags, as well as daily necessities such as toilet paper and notebooks. Its production process does not involve pulp manufacturing, but only involves forming, bonding, and printing processes on the base paper. It has the characteristics of low pollution and low emissions, and its main raw material relies on purchased paperboard.

[0003] In existing technologies, after cardboard boxes are folded and formed, they need to be trimmed to ensure that the edges can be folded into a box shape. However, during the trimming process, different materials will generate varying degrees of debris and dust. Existing technologies often rely on manual cleaning of the edges, using cleaning cloths for wiping, which is inefficient and easily leaves dust and debris residue, resulting in an unclean surface that affects the quality, delivery, and use of the boxes. Summary of the Invention

[0004] This invention proposes an air dust removal device for paper product manufacturing, which solves the problem in the prior art of how to automatically and thoroughly clean the debris and dust generated after the carton is cut, and avoid dust emission and pollution of the workshop environment.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An air dust removal device for paper product manufacturing includes a fixing mechanism for clamping and fixing the paper product to be dusted; two dust collection mechanisms are symmetrically arranged on both sides of the fixing mechanism; and an auxiliary dust removal mechanism is also included, which is directly opposite the fixing mechanism and transfers debris and dust on the paper product to the two dust collection mechanisms on both sides.

[0006] Furthermore, the fixing mechanism includes a first mounting plate on which a power motor is mounted. A first disc is fixed to the output shaft of the power motor, and the paper products to be dusted are placed on the first disc.

[0007] Furthermore, the fixing mechanism also includes a lifting platform, a first lifting drive component, a second mounting plate, and a second disc. The lifting platform is mounted on one side of the first mounting plate, and the second mounting plate is mounted on the lifting end of the lifting platform. There are two first lifting drive components, which are mounted on the first mounting plate near the lifting platform. The lifting ends of the first lifting drive components are connected to the second mounting plate. The second disc is rotatably mounted on the lower side of the second mounting plate, and the second disc is located directly above the first disc.

[0008] Furthermore, the auxiliary dust removal mechanism includes a frame facing the power motor and the first disc. Two first slide rails are symmetrically mounted on the frame. A first electric slide table is slidably mounted in each of the two first slide rails. A second slide rail is fixed to the top of the two first electric slide tables. Two second electric slide tables are slidably mounted in the second slide rails. A cleaning and collection component is mounted on each of the second electric slide tables.

[0009] Furthermore, the cleaning and collecting assembly consists of two cleaning brushes, which are symmetrically mounted on the upper and lower parts of the second electric slide.

[0010] Furthermore, the cleaning brush is equipped with an electrically controlled electrostatic generator.

[0011] Furthermore, the dust collection mechanism includes a dust collection housing, on which two telescopic hoses are connected. Each telescopic hose has a dust collection pipe connected to its end away from the dust collection housing, and the dust collection pipe is installed on the translation component. The translation component includes a first mounting frame, and four first mounting frames are provided. The four first mounting frames are installed on the working plane and are divided into two groups. A third slide rail is installed on the upper part of each group of first mounting frames. Two third electric slide tables are symmetrically slidably installed in the two third slide rails. Both sides of each dust collection pipe are fixed to the two third electric slide tables through two second mounting frames.

[0012] Furthermore, each of the dust collection pipes is equipped with an installation ring at the end away from the telescopic flexible hose, and a number of swing rods are equidistantly installed on the inner ring surface of the installation ring. The swing rods are provided with multiple branch rods at the end near the axis of the dust collection pipe.

[0013] Furthermore, the swing rod is hinged to the mounting ring, and the swing plane of the swing rod passes through the central axis of the dust collection pipe; It also includes a control component. The dust collection pipe has a strip-shaped limiting groove extending along the central axis. The control component includes a sliding seat and a moving ring. The sliding seat is slidably installed in the limiting groove. The moving ring is fixed to the sliding seat and is located inside the dust collection pipe. Several pulling rods are equidistantly connected to the moving ring. The other end of the pulling rod is hinged to the swing rod. The sliding seat is fixed to a second toothed rod at one end located outside the dust collection pipe. One end of the second toothed rod is connected to an elastic telescopic rod, and the other end of the elastic telescopic rod is fixed to the dust collection pipe. A mounting rod is fixedly connected to the dust collection pipe. A rotating shaft and a second gear are rotatably mounted on the mounting rod. A first gear and a missing gear are fixedly connected to the rotating shaft in sequence. The missing gear meshes with the second gear, and the first gear meshes with the second gear.

[0014] Furthermore, each of the dust collection pipes is provided with a control and adjustment assembly, which includes a third mounting bracket, a third mounting plate, a second lifting drive component, and a first gear. The third mounting plate is mounted on the third slide rails on both sides via the third mounting bracket, the second lifting drive component is mounted on the third mounting plate, and the first gear is mounted on the lifting end of the second lifting drive component.

[0015] The positive effects of this invention are: Two sets of cleaning brushes slide from the center of the cardboard box to both sides, physically cleaning and separating the stuck debris from the box; at the same time, the electrostatic generator on the cleaning brush is activated, using static electricity to attract the separated dust and debris onto the bristles, avoiding residue and secondary pollution caused by simple cleaning.

[0016] After the cleaning brush finishes cleaning, the dust collection tube moves horizontally and fits over the outside of the cleaning brush. At this time, the static electricity disappears, and some dust falls off naturally. Combined with the suction of the dust collection box, the first step of dust collection is completed. The whole process is carried out in a closed space to prevent dust from escaping.

[0017] During the reverse movement of the dust collection pipe, the missing gear engages with the second gear rack, driving the swing rod and the forked rod to swing back and forth, combing away the debris remaining in the cleaning brush bristles. The combed dust is collected by suction, achieving complete regeneration of the cleaning brush and ensuring the dust removal effect for continuous operation.

[0018] The toothed part of the missing gear drives the second rack, which in turn extends the elastic telescopic rod. Simultaneously, it moves the sliding seat and the moving ring closer to the swing rod. The moving ring then pushes the swing rod towards the opening of the dust collection pipe via the pull rod, causing the swing rod to swing towards the central axis of the dust collection pipe until it opens. When the toothless part of the missing gear reaches the second rack, the second rack loses its locking restraint, and the elastic force of the telescopic rod causes the second rack to reset, achieving an instantaneous pullback effect from the pull rod and a reset swing effect for the swing rod. This allows the swing rod and the forked rod to return to their original positions during the translation of the dust collection pipe. Furthermore, the swing rod and the forked rod comb away residual debris and dust from the bristles of the cleaning brush. The combed dust and debris are then collected into the dust collection box by suction, thus achieving thorough removal of dust and debris from the cleaning brush and efficient automated dust removal at the cut edges of cardboard boxes. This prevents dust and debris from escaping into the air and causing poor air quality in the workshop. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] like Figure 1-16 As shown, an air dust removal device for paper product manufacturing includes a fixing mechanism for clamping and fixing the paper product to be dusted; two dust collection mechanisms are symmetrically arranged on both sides of the fixing mechanism; and an auxiliary dust removal mechanism is also included, which is directly opposite the fixing mechanism and transfers debris and dust on the paper product to the two dust collection mechanisms on both sides.

[0022] The fixing mechanism includes a first mounting plate 1, on which a power motor 2 is mounted. A first disc 3 is fixed to the output shaft of the power motor 2, and the paper products to be dusted are placed on the first disc 3.

[0023] The fixing mechanism also includes a lifting platform 4, a first lifting drive component 5, a second mounting plate 6, and a second disc 7. The lifting platform 4 is installed on one side of the first mounting plate 1, and the second mounting plate 6 is installed on the lifting end of the lifting platform 4. There are two first lifting drive components 5, which are installed on the first mounting plate 1 near the lifting platform 4. The lifting end of the first lifting drive component 5 is connected to the second mounting plate 6. The second disc 7 is rotatably installed on the lower side of the second mounting plate 6 and is located directly above the first disc 3.

[0024] The auxiliary dust removal mechanism includes a frame 38, which faces the power motor 2 and the first disc 3. Two first slide rails 8 are symmetrically installed on the frame 38. A first electric slide table 9 is slidably installed in each of the two first slide rails 8. A second slide rail 10 is fixed to the top of the two first electric slide tables 9. Two second electric slide tables 11 are slidably installed in the second slide rails 10. A cleaning and collection component is installed on each second electric slide table 11.

[0025] The cleaning and collection assembly consists of two cleaning brushes 12, which are symmetrically mounted on the upper and lower parts of the second electric slide 11. Each cleaning brush 12 is equipped with an electrically controlled electrostatic generator, which can control the generation and cessation of static electricity in real time, thereby controlling the brush's attraction of dust and debris.

[0026] The dust collection mechanism includes a dust collection housing 13, on which two telescopic hoses 14 are connected. Each telescopic hose 14 is connected to a dust collection pipe 19 at the end away from the dust collection housing 13. The dust collection pipe 19 is installed on the translation component. The translation component includes a first mounting bracket 15, and four first mounting brackets 15 are provided. The four first mounting brackets 15 are installed on the working plane and are divided into two groups. Each group of first mounting brackets 15 has a third slide rail 16 installed on its upper part. Two third electric slide tables 17 are symmetrically slidably installed in the two third slide rails 16. The two sides of each dust collection pipe 19 are fixed to the two third electric slide tables 17 by two second mounting brackets 18.

[0027] Each dust collection pipe 19 has an installation ring 24 installed at the end away from the telescopic hose 14. Several swing rods 25 are installed at equal intervals on the inner ring surface of the installation ring 24. Several branch rods 26 are provided at the end of the swing rods 25 near the axis of the dust collection pipe 19.

[0028] The swing rod 25 is hinged to the mounting ring 24, and the swing plane of the swing rod 25 passes through the central axis of the dust collection pipe 19. It also includes a control assembly. The dust collection pipe 19 has a strip-shaped limiting groove 27 extending along the central axis. The control assembly includes a sliding seat 28 and a moving ring 29. The sliding seat 28 is slidably mounted in the limiting groove 27, and the moving ring 29 is fixed to the sliding seat 28. The moving ring 29 is located inside the dust collection pipe 19, and several pull rods 30 are equidistantly connected to the moving ring 29. The other end of each pull rod 30 is hinged. A swing arm 25 is connected to the sliding seat 28 located on the outside of the dust collection pipe 19. One end of the sliding seat 28 is fixedly connected to the second toothed rod 31. One end of the second toothed rod 31 is connected to an elastic telescopic rod 32. The other end of the elastic telescopic rod 32 is fixedly connected to the dust collection pipe 19. A mounting vertical rod 33 is fixedly connected to the dust collection pipe 19. A rotating shaft rod 34 and a second gear 37 are rotatably mounted on the mounting vertical rod 33. A first gear 35 and a missing gear 36 are fixedly connected to the rotating shaft rod 34 in sequence. The missing gear 36 meshes with the second toothed rod 31, and the first gear 35 meshes with the second gear 37.

[0029] Each dust collection pipe 19 is equipped with a control and adjustment assembly, which includes a third mounting bracket 20, a third mounting plate 21, a second lifting drive component 22, and a first gear 23. The third mounting plate 21 is mounted on the third slide rails 16 on both sides via the third mounting bracket 20. The second lifting drive component 22 is mounted on the third mounting plate 21. The first gear 23 is mounted on the lifting end of the second lifting drive component 22. The first gear 23 can disengage from and engage with the second gear 37.

[0030] Working principle: During use, the cut carton is conveyed to the position of the first disc 3 by the conveyor belt. Then, the first lifting drive 5 drives the lifting platform 4 to descend, which in turn drives the second mounting plate 6 to move downward, and then drives the second disc 7 to move downward. The downward movement of the second disc 7 clamps the carton on the first disc 3, realizing the positioning of the carton, while the edges of the carton are exposed.

[0031] Subsequently, the first motorized slide 9 moves within the first slide rail 8, causing the cleaning brush 12 to move closer to the cardboard box. Initially, both second motorized slides 11 are located in the middle of the second slide rail 10, and the two sets of cleaning brushes 12 are also close together at the middle of the cardboard box edge. Each set of cleaning brushes 12 consists of two brushes, one above the other, located on the upper and lower surfaces of the cardboard box edge, respectively. Then, the two second motorized slides 11 begin to slide to the sides of the second slide rail 10, moving away from each other. The two sets of cleaning brushes 12 then sweep away debris and dust from the cardboard box edge surface, physically cleaning away any adhering debris. Dust and debris separate from the cardboard box. At the same time, the electrostatic generator on the cleaning brush 12 is activated, and the cleaning brush 12 becomes statically charged. This allows all the debris and dust separated from the cardboard box to be attracted to the cleaning brush 12, preventing the residue of debris and dust from simple sweeping. Then, the two sets of cleaning brushes 12 leave from both sides of the cardboard box, thus completing the dust removal and cleaning of one edge of the cardboard box. Then, the power motor 2 drives the first disc 3 to rotate, and the first disc 3 drives the cardboard box on it to rotate 180 degrees, so that the other edge is facing the cleaning brush 12 for dust removal and cleaning of the other side.

[0032] In the initial state, due to the elastic force of the elastic telescopic rod 32, the toothed rod 31 is pulled. The toothed rod 31 then pulls the traction rod 30 through the sliding seat 28 and the moving ring 29, causing the traction rod 30 to pull the swing rod 25. The swing rod 25 rotates towards the inside of the dust collection pipe 19 and swings away from the central axis of the dust collection pipe 19. At this time, the swing rod 25 is in a folded state and is located close to the inner wall of the dust collection pipe 19.

[0033] After the cleaning brush 12 moves to both sides, the debris and dust carried on the cleaning brush 12 need to be collected. At this time, the two dust collection pipes 19 are aligned with the two cleaning brushes 12. Then, the third electric slide 17 slides in the third slide rail 16, and then drives the dust collection pipes 19 to move closer to the cleaning brushes 12 through the second mounting bracket 18. During the translation process, the dust collection pipes 19 will cover the outside of the cleaning brushes 12. At this time, the swing rod 25 is in a folded state, so it will not disturb the bristles on the cleaning brushes 12. During this process, the second lifting drive 22 is in a retracted state, driving the first toothed rod 23 away from the second gear 37 and in a non-meshing state. When the dust collection pipes 19 have completely covered the cleaning brushes 12, the electrostatic generator controls the static electricity on the cleaning brushes 12 to disappear. Some of the attracted dust and debris fall into the dust collection pipes 19. The suction of the dust collection box 13 sucks away some of the dust and debris in the dust collection pipes 19 through the telescopic hose 14. The first dust collection is completed, but there will still be residual debris and dust on the cleaning brush 12. At this time, the second lifting drive 22 drives the first gear 23 to move upward. The first gear 23 and the second gear 37 begin to mesh. Then, the third electric slide 17 starts to drive the dust collection pipe 19 to move in the opposite direction, moving towards disengagement from the dust collection pipe 19. Simultaneously, it drives the second gear 37 to move. The second gear 37 rolls on the first gear 23. Then, the second gear 37 drives the first gear 35 to rotate, so that the first gear 35 drives the missing gear 36 to rotate. The toothed part of the missing gear 36 drives the second gear 31 to move. The second gear 31 will stretch the elastic telescopic rod 32, and at the same time drive the sliding seat 28 to drive the moving ring 29 to move closer to the swing rod 25. Then, the moving ring 29 pushes the swing rod 25 towards the opening of the dust collection pipe 19 through the pull rod 30. Then, the swing rod 25 swings towards the central axis of the dust collection pipe 19, swinging to the open state. Figure 10 and Figure 13 As shown, the dust collection pipe 19 continues to move. When the toothless part of the missing gear 36 moves to the second toothed rod 31, the second toothed rod 31 loses the locking restriction of the missing gear 36. The elastic force of the elastic telescopic rod 32 drives the second toothed rod 31 to reset, thereby achieving the instantaneous pull-back effect of the pull rod 30 and the reset swing effect of the swing rod 25. Thus, during the translation of the dust collection pipe 19, the swing rod 25 and the forked rod 26 return to their original positions. This allows the swing rod 25 and the forked rod 26 to comb away the residual debris and dust on the bristles of the cleaning brush 12. The combed dust and debris are also collected into the dust collection box 13 by the suction. This achieves the thorough removal of dust and debris from the cleaning brush 12 and realizes efficient and automated dust removal at the cut edge of the cardboard box, avoiding the problem of dust and debris escaping into the air and causing poor air quality in the workshop.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
