Description

Technical Field

[0001] This utility model relates to the technical field of sanitary napkin paper processing equipment, specifically a dust collection device for a paper covering mechanism. Background Technology

[0002] Currently, in the production process of disposable hygiene products such as sanitary napkins, the white paper wrapping is a crucial step. In this step, absorbent materials such as cotton cores are typically wrapped and shaped using white paper. However, existing white paper wrapping mechanisms inevitably generate a certain amount of cotton core fiber fragments and fine particles of polymeric materials during high-speed conveying, cutting, or shaping of the cotton core material (such as fluff pulp) and potentially added superabsorbent polymer (SAP). These fragments and particles easily disperse and form dust.

[0003] However, in the existing technology, the dust generated by the white paper wrapping mechanism during the production process is usually cleaned locally by a traditional handheld vacuum cleaner or by relying on the overall ventilation and dust removal system of the workshop. These methods not only require dedicated manpower for operation and maintenance, but also increase the labor costs of the production enterprise.

[0004] Moreover, manual cleaning often fails to achieve real-time and comprehensive coverage, and the dust collection effect is limited. More importantly, dust that is not effectively controlled will remain suspended in the air of the production workshop, posing a potential threat to the respiratory health of on-site operators, and may also adversely affect product quality as well as the cleanliness and stability of production equipment.

[0005] Therefore, we propose to design a dust collection device for a small white paper wrapping mechanism. Utility Model Content

[0006] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0007] To address the problems of high labor costs, untimely and incomplete dust removal, and impacts on operator health and product quality in the existing technology, this utility model provides the following technical solution:

[0008] A dust collection device for a white paper wrapping mechanism includes a frame, a conveyor belt inside the frame, a fixed plate fixedly connected to one side of the outer wall of the frame, a motor fixedly connected to one end of the fixed plate, a drive shaft of the motor passing through the fixed plate and fixedly connected to a threaded rod, a slider threadedly connected to the outer wall of the threaded rod, a negative pressure pipe fixedly connected to the top of the slider, two corrugated pipes connected to the bottom of the negative pressure pipe, and a paper separating blade on the top of the frame.

[0009] A fixing rod is fixedly connected to one side wall of the fixing plate. A limit cylinder is connected to the outer side wall of the fixing rod by a bearing. The limit cylinder and the outer side wall of the conveyor belt are jointly provided with a small white paper body. A fixing frame is provided at the top of the fixing rod. A photoelectric displacement sensing module is fixedly connected to the outer side wall of the fixing frame.

[0010] As a preferred embodiment of the dust collection device of the small white paper wrapping mechanism described in this utility model, the top of the fixed plate is provided with a sliding groove, and the outer wall of the slider is slidably connected to the inner wall of the sliding groove. Under the drive of the threaded rod, the slider can be driven to slide in the sliding groove to limit the movement direction of the negative pressure tube.

[0011] As a preferred embodiment of the dust collection device for the white paper wrapping mechanism described in this utility model, the bottom of the two corrugated pipes is fixedly connected to negative pressure heads, and the two negative pressure heads are respectively located on both sides of the top of the conveyor belt. By sliding the two negative pressure heads along the edges of both sides of the conveyor belt, it is convenient to adsorb the dust remaining on both sides during the production of white paper.

[0012] As a preferred embodiment of the dust collection device for the small white paper wrapping mechanism described in this utility model, the probe of the photoelectric displacement sensing module corresponds to the middle position of the small white paper body. The probe of the photoelectric displacement sensing module measures the stroke of the small white paper, thereby controlling the periodic forward and reverse rotation of the motor drive shaft to drive the negative pressure tube to reciprocate and fully adsorb the dust on both sides of the conveyor belt.

[0013] As a preferred embodiment of the dust collection device of the small white paper wrapping mechanism described in this utility model, one end of the negative pressure pipe is connected to the suction end of the external air extractor, and the negative pressure pipe is connected to two corrugated pipes. After the negative pressure head draws the dust into the negative pressure pipe, it is discharged to a fixed external position by the external air extractor for unified treatment.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes the cooperation of a conveyor belt, a fixed plate, a negative pressure pipe, and a motor to target the key dust-generating areas of the white paper conveying mechanism. Dust collection pipes are installed at both ends of the conveying mechanism, and a central collection pipe is used to uniformly discharge the collected dust to a designated location for treatment. Displacement sensors on the conveyor line can detect the position of specific components or materials on the production line in real time. Based on this position information, the drive motor is intelligently controlled to rotate in both directions, achieving precise positioning of the dust collection port. This assists the cleaning mechanism in performing effective actions, and ultimately, through the principle of negative pressure adsorption, the dust generated during the production process is efficiently and automatically removed.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figure 1-3 This utility model provides a dust collection device for a small white paper wrapping mechanism, including a frame 1, a conveyor belt 2 inside the frame 1, a fixed plate 3 fixedly connected to one side of the outer wall of the frame 1, a motor 4 fixedly connected to one end of the fixed plate 3, a drive shaft of the motor 4 passing through the fixed plate 3 and fixedly connected to a threaded rod 5, and a slider 6 threadedly connected to the outer wall of the threaded rod 5.

[0025] The top of the fixed plate 3 is provided with a sliding groove 7. The outer wall of the slider 6 is slidably connected to the inner wall of the sliding groove 7. Driven by the threaded rod 5, the slider 6 can slide in the sliding groove 7 to limit the movement direction of the negative pressure pipe 8.

[0026] The top of the slider 6 is fixedly connected to a negative pressure pipe 8, and the bottom of the negative pressure pipe 8 is connected to two corrugated pipes 9. The bottom of the two corrugated pipes 9 is fixedly connected to a negative pressure head 10. One end of the negative pressure pipe 8 is connected to the suction end of an external air extractor, and the negative pressure pipe 8 is connected to the two corrugated pipes 9. After the negative pressure head 10 draws the dust into the negative pressure pipe 8, it is discharged to a fixed external location by the external air extractor for unified treatment.

[0027] Two negative pressure heads 10 are located on the top of the conveyor belt 2 on both sides. By sliding the two negative pressure heads 10 along the edges of the conveyor belt 2, it is easy to adsorb the dust remaining on both sides during the production of white paper.

[0028] A paper-splitting blade 11 is provided on the top of the frame 1. When the small white paper body 14 passes through the paper-splitting blade 11, it is easy to divide the small white paper into multiple strips for continued conveying.

[0029] A fixing rod 12 is fixedly connected to one side wall of the fixing plate 3. A limit cylinder 13 is connected to the outer side wall of the fixing rod 12 by a bearing. The limit cylinder 13 and the outer side wall of the conveyor belt 2 are jointly provided with a small white paper body 14. A fixing frame 15 is provided at the top of the fixing rod 12. A photoelectric displacement sensing module 16 is fixedly connected to the outer side wall of the fixing frame 15. The probe of the photoelectric displacement sensing module 16 corresponds to the middle position of the small white paper body 14. The travel of the small white paper is measured by the probe of the photoelectric displacement sensing module 16, thereby controlling the periodic forward and reverse rotation of the drive shaft of the motor 4, driving the negative pressure pipe 8 to reciprocate, and fully adsorbing the dust on both sides of the conveyor belt 2.

[0030] In use, the end of the white paper body 14 is connected to the external conveying mechanism and is driven by the conveyor belt 2. The conveying path of the white paper body 14 can be limited by the limiting cylinder 13 to keep it in a stable conveying direction.

[0031] A photoelectric displacement sensing module 16 is provided at the top of the limiting cylinder 13. The photoelectric displacement sensing module 16 includes an optical displacement sensor, a controller and a signal processing unit, which facilitates the measurement of the stroke of the white paper body 14.

[0032] After the white paper body 14 travels a certain distance, the optical displacement sensor measures the surface of the white paper in a non-contact manner and converts the displacement into an electrical signal. The controller compares this signal with the preset target position, thereby driving the motor 4 to periodically rotate forward and reverse, which in turn drives the slider 6 and the negative pressure tube 8 to move back and forth on the top of the conveyor belt 2 to adsorb the dust at the edge of the white paper body 14.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
