Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a dust removal device for the surface of flame-retardant synthetic leather. Background Art

[0002] Flame retardant synthetic leather is a permanent flame retardant product that does not burn, melt, drip, or emit black smoke when exposed to fire, and maintains flame retardant properties after multiple washings. During the processing of flame retardant synthetic leather, a lot of dust will be generated and remain. If it is directly cleaned, it is easy to cause dust, which will have a certain impact on the health of the workers. Therefore, we propose a flame retardant synthetic leather surface dust removal device;

[0003] For example, a Chinese utility model patent disclosed in the Chinese patent publication with publication number CN215314141U and authorization announcement date of December 28, 2021 discloses a surface dust removal device for synthetic leather processing, comprising a supporting base plate, a fixed plate is arranged on one side of the top of the supporting base plate, a collecting box is arranged on the top of the supporting base plate, a discharging handle is arranged on the front side wall of the collecting box, exhaust fans are symmetrically arranged on the left and right sides of the top of the supporting base plate, a material guide pipe and a collecting pipe are respectively connected between the two groups of exhaust fans and the collecting box, supporting frames are symmetrically arranged on the left and right sides of the top of the supporting base plate, a conveying device is arranged between the two groups of supporting frames, a dust removal box is arranged on the front side wall of the fixed plate, the dust removal box is located above the conveying device, shielding doors are rotatably connected to the left and right sides of the dust removal box, a material blocking device is arranged on the right shielding door, an electric push rod is arranged on the top of the dust removal box, and a dust removal device is arranged at the bottom of the electric push rod through a connecting plate;

[0004] Although the above-mentioned device uses the design of structures such as a scraper and a dust removal brush to initially clean the surface of synthetic leather, in actual use, the scraper is provided with a downward thrust by a spring, so that the scraper can smoothly contact the surface of the synthetic leather and then clean the dust on the surface of the synthetic leather, but the thrust applied by the spring cannot be adjusted, that is, the thrust of the spring on the scraper is always constant, so when the scraper faces thicker synthetic leather, it is easy to scratch the surface of the synthetic leather. In addition, the above-mentioned device uses a dust removal brush to brush the surface of synthetic leather to brush off the dust on the surface of synthetic leather, but static electricity is generated in the process of the dust removal brush brushing, so some dust will be firmly attached to the surface of synthetic leather due to the influence of static electricity, and the dust generated when the dust removal brush brushes may be attached to the surface of synthetic leather under the influence of static electricity, thereby resulting in poor dust removal effect of synthetic leather. Utility Model Content

[0005] The utility model aims to provide a dust removal device for the surface of flame-retardant synthetic leather, so as to solve the problem that the flame-retardant synthetic leather is prone to generate dust during dust removal.

[0017] The utility model uses two cleaning rollers to brush the two sides of the synthetic leather, thereby brushing off the dust on the surface of the synthetic leather, or loosening the dust firmly attached to the surface of the synthetic leather, so as to facilitate subsequent cleaning. The baffle and the guide plate are designed to prevent the dust generated when the cleaning rollers are brushing from floating around in the box, and the dust will fall into the dust collecting box along the guide plate. In addition, the first vacuum cleaner and the second vacuum cleaner are designed to suck away the dust loosened by the cleaning rollers, thereby improving the dust removal effect. The second motor is designed to drive the bidirectional threaded rod to rotate, so that the two dust hoods can move synchronously in opposite directions, so as to adjust the distance between the two dust hoods, so that synthetic leathers of different thicknesses can pass through. In addition, since the cleaning roller generates static electricity when brushing the surface of the synthetic leather, some dust is firmly attached to the surface of the synthetic leather due to static electricity. Therefore, the dust on the surface of the synthetic leather that has not been cleaned due to static electricity is cleaned up by the design of the electrostatic dust removal rubber roller, thereby improving the dust removal effect of the synthetic leather.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figure 1-5 The utility model provides a technical solution: a dust removal device for the surface of flame-retardant synthetic leather, comprising a box body 1, two cleaning rollers 2 are rotatably connected to the top of the inner wall of the box body 1, one end of the two cleaning rollers 2 are fixedly connected to a first gear 3, the two first gears 3 are meshed and connected, the box body 1 is located at both ends of the two cleaning rollers 2 and are respectively fixedly connected to baffles 4, the bottom of the baffle 4 is fixedly connected to a guide plate 5, a first dust collector 6 is arranged on the top of the box body 1, and a second dust collector 7 is arranged at one end of the bottom of the guide plate 5, the first dust collector 6 and the second dust collector 7 are connected to a dust cover 9 through a connecting pipe 8, and the two dust covers 9 are symmetrically arranged and slidably connected to the box body 1,

[0026] In this embodiment, the design of two cleaning rollers 2 facilitates cleaning of both sides of the synthetic leather. The surface of the cleaning roller 2 is provided with a plurality of relatively soft bristles, which not only improves the cleaning effect of the cleaning roller 2 but also does not cause damage to the synthetic leather. In actual use, only the bristles of the cleaning roller 2 are in contact with the synthetic leather. The design of the first gear 3 allows the two cleaning rollers 2 to rotate synchronously in opposite directions. In this way, when in use, only one cleaning roller 2 needs to be driven to rotate, and the other cleaning roller 2 can rotate. In addition, the baffle 4 is located at both ends of the cleaning roller 2, and the synthetic leather will pass through the baffle 4 during the movement. The guide plate 5 at the bottom of the baffle 4 is in the shape of a rectangular duct and extends to the bottom of the box 1. In this way, under the action of the baffle 4 and the guide plate 5, the dust generated when the cleaning roller 2 is brushed will not float around. In addition, the dust on the surface of the synthetic leather that is not brushed off by the cleaning roller 2 is sucked away by the design of the first vacuum cleaner 6 and the second vacuum cleaner 7. The synthetic leather passes between the two dust hoods 9, so that both sides of the synthetic leather can be cleaned.

[0027] A first through hole 10 is provided at one end of the baffle 4. In the present embodiment, the design of the first through hole 10 allows the synthetic leather to pass through the baffle 4 smoothly. In actual use, a brush can be arranged around the first through hole 10, so that the dust generated by the cleaning roller 2 brushing the synthetic leather is difficult to float out from the first through hole 10.

[0028] A plurality of guide rollers 11 are rotatably connected inside the housing 1. In the present embodiment, the design of the guide rollers 11 allows the synthetic leather to smoothly pass between the two cleaning rollers 2 and between the two dust hoods 9 in the housing 1.

[0029] A first motor 12 is fixedly connected to one end of the outer wall of the box body 1, and the output end of the first motor 12 is fixedly connected to the cleaning roller 2. In the present embodiment, since a driving force is required for the cleaning roller 2 to rotate, the first motor 12 is designed to drive the cleaning roller 2 to rotate. It should be noted that the two cleaning rollers 2 are meshed and connected together through two first gears 3, so only one first motor 12 needs to be installed to drive the two cleaning rollers 2 to rotate at the same time.

[0030] The two ends of the dust hood 9 are respectively fixedly connected with connecting blocks 13, one end of the connecting block 13 is fixedly connected with a slider 14, and the inner walls of the box body 1 are respectively provided with sliding grooves 15 at both ends of the dust hood 9, and the slider 14 is slidingly connected with the sliding groove 15. In this embodiment, the design of the slider 14 and the sliding groove 15 allows the two dust hoods 9 to be smoothly slidably connected with the box body 1.

[0031] A second motor 16 is fixedly connected to one end of the box body 1 adjacent to the slide groove 15, and a bidirectional threaded rod 17 is fixedly connected to the output end of the second motor 16. The bidirectional threaded rod 17 is threadedly connected to the connecting block 13. In this embodiment, the bidirectional threaded rod 17 is driven to rotate by the second motor 16, thereby driving the two dust hoods 9 to move synchronously in opposite directions, so that the distance between the two dust hoods 9 can be adjusted, thereby facilitating the passage of synthetic leather of different thicknesses.

[0032] A dust box 18 is slidably connected to the bottom of the inner wall of the box body 1, a second through hole 25 is provided at one end of the side wall of the box body 1, and a dust shield 19 adapted to the second through hole 25 is fixedly connected to one end of the dust box 18. In the present embodiment, the dust falling from the guide plate 5 is collected by the dust box 18, wherein the guide plate 5 is located above the side wall of the dust box 18, thereby facilitating the removal of the dust box 18. In addition, the top of the second through hole 25 is higher than the top of the second vacuum cleaner 7 (excluding the connecting pipe 8), so that the operator can easily clean the dust inside the second vacuum cleaner 7. In addition, the dust shield 19 completely covers the second through hole 25, thereby preventing dust from floating to the outside of the box body 1, and a handle is installed on the outer wall of the dust shield 19.

[0033] A feed port 20 is provided at one end of the top of the side wall of the box body 1 , and a discharge port 21 is provided at the bottom of the side wall of the box body 1 away from the feed port 20 . In this embodiment, the design of the feed port 20 and the discharge port 21 allows the synthetic leather to pass through the box body 1 smoothly.

[0034] Two electrostatic dust removal rubber rollers 22 are rotatably connected inside the box body 1 at adjacent positions to the discharge port 21. One end of the two electrostatic dust removal rubber rollers 22 is fixedly connected to a second gear 23, and the two second gears 23 are meshingly connected. In this embodiment, under the action of the electrostatic field generated by the electrostatic dust removal rubber roller 22, the charges from the local electrostatic field will be adsorbed to the surface of the object, thereby causing electrostatic adsorption of the dust and the electrostatic dust removal rubber roller 22, allowing the dust to adhere tightly to the electrostatic dust removal rubber roller 22, wherein the electrostatic field generated by the electrostatic dust removal rubber roller 22 is much larger than the electrostatic field generated by the cleaning roller 2 brushing the synthetic leather.

[0035] A third motor 24 is fixedly connected to one end of the outer wall of the box body 1, and the output end of the third motor 24 is fixedly connected to the electrostatic dust removal rubber roller 22. In the present embodiment, the electrostatic dust removal rubber roller 22 is driven to rotate by the third motor 24, so as to prevent dust from concentrating on a certain part of the electrostatic dust removal rubber roller 22. Since the two electrostatic dust removal rubber rollers 22 are meshed and connected together by two second gears 23, only one third motor 24 needs to be installed to simultaneously drive the two electrostatic dust removal rubber rollers 22 to rotate.

[0036] Working principle: When in use, first turn on the first motor 12, then the two cleaning rollers 2 will rotate synchronously in opposite directions, thereby brushing the surface of the synthetic leather. The dust brushed off will fall into the dust box 18 along the guide plate 5. In addition, the dust generated during the brushing process will not float around due to the obstruction of the baffle 4 and the guide plate 5. After the first motor 12 is turned on, the first vacuum cleaner 6 and the second vacuum cleaner 7 are turned on at the same time. Under the action of the first vacuum cleaner 6 and the second vacuum cleaner 7, the dust on the surface of the synthetic leather will enter the connecting pipe 8 along the dust cover 9, and finally enter the first vacuum cleaner 6 and the second vacuum cleaner 7. When facing synthetic leathers of different thicknesses, it is necessary to adjust the distance between the two dust covers 9. At this time, turn on the first motor 12, and under the drive of the second motor 16, the bidirectional threaded rod 17 will rotate, thereby driving the two dust hoods 9 to move synchronously in the opposite direction, and then the distance between the two dust hoods 9 can be adjusted, so that synthetic leather of different thicknesses can pass smoothly. Since the cleaning roller 2 generates static electricity when brushing the synthetic leather, some dust will firmly adhere to the surface of the synthetic leather under the action of static electricity, and it is difficult for the first vacuum cleaner 6 and the second vacuum cleaner 7 to completely suck away the dust. Therefore, two electrostatic dust removal rubber rollers 22 are arranged at adjacent positions of the discharge port 21 in the box body 1. Under the action of the electrostatic dust removal rubber rollers 22, the dust attached to the surface of the synthetic leather due to static electricity can be cleaned up. In actual operation, the third motor 24 can be turned on to drive the two electrostatic dust removal rubber rollers 22 to rotate synchronously in the opposite direction, so as to avoid the dust from concentrating on a certain point of the electrostatic dust removal rubber rollers 22.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
