[0002] In the processing of disposable hygiene products, large rolls of raw materials are flattened, cut, and folded. The cutting step involves cutting rollers and negative pressure rollers. The cutting rollers have cutters, and the negative pressure rollers have several air holes. Negative pressure air enters the negative pressure rollers through the air holes. During cutting, the negative pressure air adsorbs the disposable hygiene products onto the negative pressure rollers for cutting. After cutting is completed, the adsorption ends, and the folding mechanism folds them.

[0003] The standard practice for using negative pressure air now is to install a negative pressure fan unit next to the folding and slitting device, which is connected to the folding and slitting device through pipes to provide negative pressure air to the negative pressure roller.

[0004] Negative pressure fans are bulky and require more floor space; the connection between the negative pressure fan and the folding and cutting device via pipes can also cause losses due to the excessive length of the pipes; and the air blown out of the negative pressure fan is not utilized and is directly discharged outdoors, resulting in a significant waste of resources.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The system includes a frame plate 1, several structural frames 2 installed between the frame plates 1, and cutter rollers 3 and negative pressure rollers 4 rotatably connected between the frame plates 1. Further, a vacuum pump 10 is detachably connected to any position on the frame plate 1, and the input end of the vacuum pump 10 is connected to the negative pressure roller 4 via a pipeline. The vacuum pump 10 includes a drive device 12, which is detachably connected to any position on the frame plate 1. A turbine fan 13 is detachably connected to the output end of the drive device 12. An input connection pipe 14 is installed at the input end of the turbine fan 13, and a distribution pipe 15 is detachably connected to the input connection pipe 14. The input connection pipe 14 and the distribution pipe 15 are connected, and the distribution pipe 15 is detachably connected to the top of the frame plate 1. The distribution pipe 15 is connected to the negative pressure roller 4 via a pipeline, and an output connection pipe 17 is installed at the output end of the turbine fan 13.

[0025] The shelf 1 consists of two pieces, supported by six structural frames 2 between them. These six structural frames 2 are part of the shelf 1. The cutter and negative pressure roller 4 between the two shelf 1 pieces are responsible for cutting disposable sanitary products according to design requirements. Because the vacuum pump 10 provides negative pressure to the negative pressure roller 4, it can be connected to the negative pressure roller 4 via pipelines. Therefore, the vacuum pump 10 can be installed at any position on the shelf 1. The output connection pipe 17 and input connection pipe 14 installed on the turbine blower 13 have convenient disassembly and extension functions for connecting to other pipelines, allowing the turbine blower 13 to be installed in a suitable position. The distribution pipe 15 is designed according to requirements. It needs to be installed in the middle of the top of the two frame plates 1. This position allows for better communication with the negative pressure roller 4. During operation, the drive device 12 drives the turbine fan 13 to rotate. The turbine fan 13 draws in air from the input connecting pipe 14, which promotes air circulation. The intake connecting pipe is connected to the distribution pipe 15, which is connected to the negative pressure roller 4 through a pipeline. At the same time, the air drawn in by the turbine fan 13 is carried out through the output connecting pipe 17, thus providing negative pressure air to the negative pressure roller 4. This design structure achieves the effect of small space occupation without affecting supply and demand, and also reduces the occurrence of negative pressure air loss caused by excessively long pipeline connections.

[0026] Furthermore, the distribution pipe 15 is connected to several branch pipes 16, and the branch pipes 16 are connected to the negative pressure roller 4 through pipelines.

[0027] The distribution pipe 15 is connected to eight branch pipes 16, with four at one end near the input connection pipe 14 and four at the other end. The diameter of the branch pipes 16 is designed according to the negative pressure required at each position of the negative pressure roller 4. Generally, the diameter of the four branch pipes 16 near the input connection pipe 14 is smaller than the diameter of the other four branch pipes 16. This design enables the negative pressure roller 4 to more accurately and evenly adsorb disposable hygiene products through the adsorption points.

[0028] Furthermore, a filter element 18 is detachably connected inside the input connection pipe 14.

[0029] The filter element 18 inside the input connecting pipe 14 can filter impurities that fall from disposable hygiene products, and can protect the turbine fan 13 and the cleanliness of the exhaust air.

[0030] Furthermore, the input and output ports of the input connector 14 are symmetrically provided with speaker interfaces 19.

[0031] Figure 3The direction indicated by the middle arrow is the airflow direction. The port closer to the right arrow is the input port, and the port further away from the arrow on the left is the output port. The horn-shaped interfaces 19 symmetrically arranged inside the input connection pipe 14 can allow the incoming and outgoing air to pass through the filter element 18 better, reducing the maintenance cost of the filter element while ensuring ventilation volume. The arrow indicates the flow direction of the negative pressure air.

[0032] Furthermore, the output connector 17 has a built-in muffler.

[0033] The high-speed contact between the turbine fan 13 and the air will generate noise. By adding a silencer to the output connection pipe 17 at the output end of the turbine fan 13, the impact of the noise generated can be reduced.

[0034] Furthermore, the vacuum pump 10 also includes a pump body bracket 11, the drive unit 12 is detachably connected to the frame plate 1 via the pump body bracket 11, and the turbine fan 13 is detachably connected to the pump body bracket 11.

[0035] The pump body bracket 11 is detachably connected to the turbine fan 13 and the drive unit 12. By integrating them into the pump body bracket 11, it is easy to install and maintain, and at the same time, it provides stable support. The drive unit 12 can be a brushless motor, a DC motor, a stepper motor, or a servo motor.

[0036] Furthermore, the pump body bracket 11 can be detachably connected to any one of the following positions on the frame plate 1: top left, top right, top middle, bottom left, and bottom other side.

[0037] The pump body bracket 11 is preferably located in any one of the following positions: top left, top right, top middle, bottom left, and bottom other side. This allows it to be integrated with the frame plate 1 without affecting other existing devices and parts. The optimal choice is to place the pump body bracket 11 in the middle of the top outer side of either of the two frame plates 1. This allows the turbine fan 13 to be closer to the distribution pipe 15, reducing the occurrence of reduced wind pressure due to excessively long pipes, and further improving the negative pressure wind force generated by the turbine fan 13.

[0038] Furthermore, the structural frame 2 is a hollow design, and the output connecting pipe 17 is connected to either end of the structural frame 2 through a pipeline.

[0039] The structural frame 2 is hollow, which can reduce weight while providing support for the frame plate 1. The high-speed contact between the turbine fan 13 and the air generates heat. By connecting the output connecting pipe 17 to the six structural frames 2, the working environment temperature can be increased when the working environment temperature is low, thus reducing the energy consumption of other heating devices.

[0040] Furthermore, the end of the structural frame 2 that is away from the pipe connected to the output connection pipe 17 is connected to a pipe wind turbine.

[0041] The wind speed is still high through the six structural frames 2, which can collect the wind in the six structural frames 2 to power the pipeline wind turbine, further recovering energy and improving economic efficiency.

[0042] To elaborate further, the output end of the pipeline wind turbine is connected to the motor that needs cooling through a pipeline.

[0043] The equipment for processing disposable hygiene products requires several motors to drive it. The wind speed and temperature are greatly reduced by the wind turbine through the pipeline. At this time, the excess air from the wind turbine can be transported to the motors that need heat dissipation through the pipeline, which can reduce the occurrence of motor overheating, reduce the motor failure rate, and extend the service life.

[0044] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
