Description

Technical Field

[0001] The invention belongs to the technical field of papermaking dust removal, and more specifically, particularly relates to a safe and efficient dust removal device for a papermaking machinery rewinder. Background Art

[0002] A rewinder is a special equipment for paper, mica tape and film. Its purpose is to rewind the paper rolls (called base paper rolls) produced by the papermaking machine in sequence. After rewinding, the paper is made into finished paper and shipped out. It has become a development trend in the papermaking machinery industry to use AC drive instead of DC drive for rewinders. The paper rolls rolled by the paper reel are relatively soft, and may be damaged or broken inside, with uneven edges on both sides and paper width. They cannot be directly used in paper processing or printing machines. They must be rewound on the paper roll core to form finished paper rolls of certain specifications and certain tightness requirements before they can be shipped out.

[0003] 1. Due to the particularity of paper in the pulping process, mechanical stirring, grinding and other operations will release dust and impurities in the raw materials, making it easy for dust to fly in the surrounding environment, and making it easy for dust to adhere to the surface of the formed paper and be transported. As a result, in the subsequent rewinding process of the paper, some dust is likely to remain on the surface of the paper and easily fall into the winder and rewinder, affecting the use. The practicality is insufficient and needs to be improved;

[0004] 2. The existing rewinding machine usually adopts a simple dust suction process when removing dust. Since some dust will adhere to the surface of the paper through static electricity, the suction force of the dust suction is difficult to remove the dust on the surface of the paper without anti-static treatment, and the practicality is insufficient and needs to be improved;

[0005] 3. The existing rewinding machine usually adopts a simple dust suction process when performing dust removal. Since the rewound paper has been wound by the paper reel before, the dust on the surface of the paper will be firmly adhered to the surface of the paper. At this time, the suction force generated by the dust suction process is difficult to complete the treatment of the paper dust, which leads to low dust removal efficiency and insufficient practicality, which needs to be improved;

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a safe and efficient papermaking machinery rewinder dust removal device is provided, in order to achieve a more practical purpose. Summary of the invention

[0007] In order to solve the above technical problems, the present invention provides a safe and efficient dust removal device for a papermaking machinery rewinder to solve the above problems.

[0008] A safe and efficient dust removal device for a papermaking machine rewinder, comprising a rewinder body:

[0009] Dust removal mechanisms are symmetrically and fixedly installed at the upper end of the rewinder body;

[0010] The dust removal mechanism includes brackets. The overall shape of the two brackets is "Ji" shaped. Chutes are symmetrically opened on the inner sides of the two brackets. Connecting rods are slidably installed inside each chute. Connecting blocks are fixedly installed between every two of the connecting rods. The overall shape of the two connecting blocks is funnel-shaped. A housing is fixedly installed between the two connecting blocks. The interior of the housing is hollow. The housing is located inside the rewinder body. An ion air bar is provided on the side wall of the housing. An air outlet is provided at the lower end of the ion air bar. The input pipe of the ion air bar is connected to an air pump. A first through groove is penetrated and opened on the side wall of the housing. A dust suction head is fixedly installed on the side wall of the housing away from the ion air bar. A second through groove is penetrated and opened inside the dust suction head. The overall shape of the second through groove is L-shaped. The pipe of the dust suction head is connected to a vacuum cleaner. The pipe connecting the dust suction head and the vacuum cleaner is a flexible pipe. The housing, the ion air bar, and the dust suction head are integrally in a "C" shape.

[0011] Preferably, the housing communicates with the inside of the dust suction head through the first through groove and the second through groove. A rotating shaft is rotatably installed inside the housing. Part of the rotating shaft is exposed outside the housing.

[0012] Preferably, first gears are symmetrically and fixedly installed on the circumferential surface of the rotating shaft. Both of the first gears are located outside the housing. A cleaning roller is fixedly installed on the circumferential surface of the rotating shaft. The cleaning roller is located inside the housing. A retaining bar is fixedly installed inside the housing.

[0013] Preferably, the retaining bar is located on one side of the first through groove. The cleaning roller is adapted to the retaining bar.

[0014] Preferably, limiting grooves are symmetrically opened on the side walls of each chute. Limiting blocks are slidably installed inside each limiting groove. Each limiting block is fixedly installed with the connecting rod.

[0015] Preferably, electric telescopic rods are fixedly installed at the upper ends of the two brackets. The output shafts of the two electric telescopic rods are slidably installed with the brackets. The output shafts of the two electric telescopic rods are fixedly installed with the connecting blocks. A tension roller assembly is provided inside the rewinder body. Second gears are symmetrically and fixedly installed on the circumferential surface of the tension roller assembly. Both of the second gears are parallel to the first gears. Both of the second gears are meshed with the first gears. The housing, the ion air bar, and the dust suction head are located above the tension roller assembly.

[0016] Preferably, a winding roller is provided inside the rewinder body. The winding roller is adapted to the ion air bar. A winding roller is provided inside the rewinder body. The winding roller is adapted to the dust suction head.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, by turning on the electric telescopic rod, the output shaft of the electric telescopic rod can pull the shell, the ion wind rod, and the dust collector head to rise through the connecting block, thereby avoiding the shell, the ion wind rod, and the dust collector head being located on the surface of the tension roller assembly to affect the worker's winding, avoid pinching hands, and improve portability and safety.

[0019] In the present invention, by providing an ion wind rod, a shell and a dust collector head, the dust on the paper can first be driven away by the ion wind rod to remove the dust adhering to the surface of the paper due to static electricity, so that the dust is in a loose state. At the same time, through the shell, the rotation of the tension roller assembly can indirectly drive the cleaning roller to rotate, so that the cleaning roller can complete the cleaning of the dust that is not adhering to the paper due to static electricity, thereby basically eliminating the dust on the paper, and subsequently the dust can be uniformly collected by the dust collector head, which greatly improves the overall dust removal rate of the device and improves its practicality.

[0020] In the present invention, by setting the second gear and the first gear, when the tension roller assembly rotates, it can actively drive the second gear to rotate and mesh with the first gear, so that the first gear can produce a direction opposite to the second gear and drive the cleaning roller to rotate, thereby completing the cleaning of the paper. At the same time, it can also improve the energy saving performance of the device to a certain extent and improve the practicality.

[0021] In the present invention, since the cleaning of dust by the cleaning roller will cause some dust to adhere to the cleaning roller, by providing a baffle bar inside the shell, when the cleaning roller rotates, the cleaning cotton strips of the cleaning roller will actively collide with the baffle bar, thereby having a shaking effect on the cleaning cotton strips, and by providing the first through groove and the second through groove, the dust can directly enter the interior of the vacuum cleaner head through the first through groove and the second through groove for processing, thereby further improving the overall practicality of the device.

[0022] In the present invention, by arranging an ion wind rod and a dust collector head on the side wall of the shell, efficient dust removal can be achieved. At the same time, since the overall shape of the shell, the ion wind rod and the dust collector head is combined into a "C" shape, the shell, the ion wind rod and the dust collector head can fit the paper to the greatest extent for dust removal, thereby further improving the dust removal effect.

[0023] In the present invention, by optimizing the structure and layout of the device, the dust removal mechanism is installed as a whole on the bracket, so that the staff only needs to install the bracket on the rewinding machine body to complete efficient dust removal processing. The modification cost is low, which is conducive to promotion and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] See also Figure 1 - Figure 8 The present invention provides a safe and efficient dust removal device for a papermaking machine rewinder, comprising a rewinder body 11:

[0035] A dust removal mechanism is symmetrically fixedly mounted on the upper end of the rewinding machine body 11;

[0036] The dust removal mechanism includes a bracket 12. The overall shape of the two brackets 12 is "U-shaped". Symmetrical sliding grooves 13 are provided on the inner sides of the two brackets 12. A connecting rod 14 is slidably installed inside each sliding groove 13. Connecting blocks 15 are fixedly installed between every two connecting rods 14. The overall shape of the two connecting blocks 15 is funnel-shaped. A housing 16 is fixedly installed between the two connecting blocks 15. The interior of the housing 16 is hollow. The housing 16 is located inside the rewinder body 11. An ion air bar 17 is provided on the side wall of the housing 16. An air outlet is provided at the lower end of the ion air bar 17. The input pipe of the ion air bar 17 is connected to an air pump. A first through groove 18 is penetratingly provided on the side wall of the housing 16. A dust suction head 19 is fixedly installed on the side wall of the housing 16 away from the ion air bar 17. A second through groove 21 is penetratingly provided inside the dust suction head 19. The overall shape of the second through groove 21 is L-shaped. The pipe of the dust suction head 19 is connected to a vacuum cleaner. The pipe connecting the dust suction head 19 and the vacuum cleaner is a flexible hose. The housing 16, the ion air bar 17, and the dust suction head 19 are integrally in a "C" shape. By optimizing the structure and layout of the device, the dust removal mechanism is integrally installed on the bracket 12, enabling the staff to simply install the bracket 12 on the rewinder body 11 in the future to complete efficient dust removal. The modification cost is low, facilitating promotion, with strong practicability. Also, by setting the ion air bar 17, the housing 16, and the dust suction head 19, the dust on the paper can first be removed by the ion air bar 17, removing the dust electrostatically adhered to the paper surface and making the dust in a loose state. At the same time, through the housing 16, the rotation of the tension roller assembly 29 can indirectly drive the cleaning roller 24 to rotate, enabling the cleaning roller 24 to clean the dust not electrostatically adhered to the paper, thus basically eliminating the dust on the paper. Subsequently, the dust can be uniformly collected through the dust suction head 19, greatly improving the overall dust removal rate of the device and enhancing practicability.

[0037] The housing 16 communicates with the inside of the dust suction head 19 through the first through groove 18 and the second through groove 21. A rotating shaft 22 is rotatably installed inside the housing 16. Part of the rotating shaft 22 is exposed outside the housing 16. By providing the first through groove 18 and the second through groove 21, the dust can directly enter the inside of the dust suction head 19 through the first through groove 18 and the second through groove 21 for processing, further improving the overall practicability of the device.

[0038] The first gears 23 are symmetrically fixedly installed on the circumferential surface of the rotating shaft 22, and the two first gears 23 are both located outside the shell 16. A cleaning roller 24 is fixedly installed on the circumferential surface of the rotating shaft 22, and the cleaning roller 24 is located inside the shell 16. A baffle 25 is fixedly installed inside the shell 16, and the baffle 25 is located on one side of the first through groove 18. The cleaning roller 24 is adapted to the baffle 25. Since the cleaning of dust by the cleaning roller 24 will cause some dust to adhere to the cleaning roller 24, by arranging the baffle 25 inside the shell 16, when the cleaning roller 24 rotates, the cleaning cotton strip of the cleaning roller 24 will actively collide with the baffle 25, thereby having a shaking effect on the cleaning cotton strip.

[0039] Limiting grooves 26 are symmetrically provided on the side walls of each slide groove 13, and a limiting block 27 is slidably installed inside each limiting groove 26. Each limiting block 27 is fixedly installed with the connecting rod 14. By setting the limiting blocks 27, when the electric telescopic rod 28 pulls the connecting block 15 to rise, it will synchronously drive the connecting rod 14 and the limiting block 27 to slide inside the slide groove 13 and the limiting groove 26 respectively, thereby providing additional limiting and increasing stability.

[0040] Electric telescopic rods 28 are fixedly installed on the upper ends of the two brackets 12, and the output shafts of the two electric telescopic rods 28 are slidably installed with the brackets 12, and the output shafts of the two electric telescopic rods 28 are fixedly installed with the connecting block 15. By turning on the electric telescopic rods 28, the output shafts of the electric telescopic rods 28 can pull the shell 16, the ion wind rod 17, and the dust collector head 19 to rise through the connecting block 15, thereby avoiding the shell 16, the ion wind rod 17, and the dust collector head 19 being located on the surface of the tension roller assembly 29. The influence on the staff's winding is avoided, the hands are avoided, and the portability and safety are improved.

[0041] A tension roller assembly 29 is provided on the inner side of the rewinder body 11, and a second gear 33 is symmetrically fixedly installed on the circumferential surface of the tension roller assembly 29. The two second gears 33 are parallel to the first gear 23, and the two second gears 33 are meshed with the first gear 23. The shell 16, the ion wind rod 17, and the dust collector 19 are located above the tension roller assembly 29. A winding roller 31 is provided on the inner side of the rewinder body 11, and the winding roller 31 is adapted to the ion wind rod 17. A winding roller 32 is provided on the inner side of the rewinder body 11, and the winding roller 32 is adapted to the dust collector 19. By setting the second gear 33 and the first gear 23, when the tension roller assembly 29 rotates, it can actively drive the second gear 33 to rotate and mesh with the first gear 23, so that the first gear 23 can produce a steering direction opposite to the second gear 33 and drive the cleaning roller 24 to rotate, so that the cleaning of the paper can be completed. At the same time, the energy saving performance of the device can be improved to a certain extent, and the practicality can be improved.

[0042] Working principle:

[0043] In the first step, when using, the staff can first turn on the electric telescopic rod 28, so that the output shaft of the electric telescopic rod 28 rises, and then pulls the connecting block 15 to rise as a whole, so that the connecting block 15 drives the connecting rod 14 and the limit block 27 to slide in the slide groove 13 and the limit groove 26 respectively, thereby driving the shell 16, the ion wind rod 17, and the dust collector head 19 to move upward through the connecting block 15, and then the staff can install the paper roll that needs to be rewound in the winding roller 31, and install the wound paper roll on the winding roller 32, and wrap the paper roll at the end of the winding roller 31 around the tension roller assembly 29 and connect it to the winding roller 31;

[0044] By turning on the electric telescopic rod 28, the output shaft of the electric telescopic rod 28 can pull the shell 16, the ion wind rod 17, and the dust head 19 to rise through the connecting block 15, thereby avoiding the shell 16, the ion wind rod 17, and the dust head 19 being located on the surface of the tension roller assembly 29 to affect the worker's winding, avoid pinching hands, and improve portability and safety.

[0045] In the second step, the staff can then connect the input pipe of the ion wind rod 17 (the ion wind rod 17 is an existing device, which is a special device for fixed static elimination and belongs to a rod-type static elimination product) to the output pipe of the air pump, and connect the pipe of the dust collector head 19 to the vacuum cleaner. Then the staff can turn on the rewinder body 11, the air pump (the air pump is an existing structure, which is mainly a device for removing air from a closed space or adding air from a closed space. It uses electricity to continuously compress the air to generate air pressure to achieve inflation, exhaust and other effects), the vacuum cleaner and the tension roller assembly 29 (the tension roller assembly 29 is an existing structure, consisting of a tension roller and a motor). At this time, the tension roller assembly 29 and the winding roller 31 of the rewinder body 11 will actively rotate, and the paper will be transported on the tension roller assembly 29. At the same time, since the inside of the ion wind rod 17 will be in a high-voltage electric field state, under the action of high voltage, the gas molecules blown out by the air pump (such as oxygen or water molecules in the air) will be dissociated into positive ions and negative ions. These ions start to move under the action of the electric field, generating an airflow of charged ions, namely "ion wind", so that the ion wind removes static electricity from the surface of the paper. At this time, the elimination of static electricity will achieve the dust that was originally attached to the surface of the paper by static electricity. Adhere to the paper and be in a loose state;

[0046] By providing the ion wind rod 17, the shell 16 and the dust collector head 19, the dust on the paper can first be removed by the ion wind rod 17 due to static electricity adhering to the surface of the paper, so that the dust is in a loose state. At the same time, through the shell 16, the rotation of the tension roller assembly 29 can indirectly drive the cleaning roller 24 to rotate, so that the cleaning roller 24 can complete the cleaning of the dust that is not adhering to the paper due to static electricity, thereby basically eliminating the dust on the paper, and subsequently the dust can be uniformly collected by the dust collector head 19, which greatly improves the overall dust removal rate of the device and improves its practicality.

[0047] In the third step, due to the rotation of the tension roller assembly 29, the tension roller assembly 29 will actively drive the second gear 33 to rotate, thereby causing the second gear 33 to mesh with the first gear 23, so that the first gear 23 generates a radial force to drive the shaft 22 to rotate inside the housing 16. At the same time, the rotation of the shaft 22 will cause the cleaning roller 24 to contact the surface of the paper, thereby sweeping away the dust on the surface of the paper that is not adhered to by static electricity. At the same time, the dust collector 19 will vacuum the dust on the surface of the paper and uniformly transport the dust into the dirt box inside the vacuum cleaner.

[0048] By setting the second gear 33 and the first gear 23, when the tension roller assembly 29 rotates, it can actively drive the second gear 33 to rotate and mesh with the first gear 23, so that the first gear 23 can produce a direction opposite to the second gear 33 and drive the cleaning roller 24 to rotate, thereby completing the cleaning of the paper. At the same time, it can also improve the energy saving performance of the device to a certain extent and improve the practicality.

[0049] In the fourth step, when the rotating shaft 22 rotates, the rotation of the rotating shaft 22 will cause the cleaning cotton strip of the cleaning roller 24 to collide with the blocking strip 25, thereby shaking the cleaning cotton strip of the cleaning roller 24, so that the dust stuck on the surface of the rotating shaft 22 can be shaken off, and the dust is transported into the interior of the dust collector 19 through the first through groove 18 and the second through groove 21 for processing;

[0050] Since the cleaning roller 24 cleans the dust, some of the dust will adhere to the cleaning roller 24. By setting a baffle 25 inside the shell 16, when the cleaning roller 24 rotates, the cleaning cotton strip of the cleaning roller 24 will actively collide with the baffle 25, thereby having a shaking effect on the cleaning cotton strip.

[0051] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
