Description

Technical Field

[0001] The utility model relates to an air blowing separation device, in particular to a suspended air blowing separation device applied to the field of paper feeding machines. Background Art

[0002] The paper feeding mechanism of existing die-cutting machines generally adopts a leading edge paper feeding mechanism. The working principle of the leading edge paper feeding mechanism is that the corrugated cardboard is placed on a bellows that can generate negative pressure through a fan, and the rotation of the friction wheel on the bellows drives the corrugated cardboard forward until it is sent between the upper and lower paper feeding rollers, and then the paper is fed forward by the paper feeding rollers. The paper feeding mechanism is usually equipped with a blowing device during use.

[0003] During use, the paper feeding mechanism will transport corrugated paper of different thicknesses and quantities. As the quantity and thickness of the corrugated paper increase, the airflow strength requirement becomes higher. The stronger the wind force, the greater the power consumption of the blower. Long-term use will not only result in high operating costs, but the blower will also be prone to aging and damage, thereby increasing the maintenance cost of the paper feeding mechanism. Utility Model Content

[0004] In response to the above-mentioned existing technology, the technical problem to be solved by the present invention is that when the existing blowing device changes the airflow intensity, it is usually adjusted directly through a blower. However, after long-term use, not only does the blower consume a lot of electricity, but the blower is also prone to aging and damage, thereby increasing the later maintenance cost of the paper feeding mechanism.

[0005] In order to solve the above problems, the utility model provides a suspended blowing separation device, comprising a blower and a mounting tube fixedly connected to the air outlet of the blower, the outer surface of the mounting tube is fixedly connected to two telescopic hoses, the end of the telescopic hose away from the mounting tube is fixedly connected to the fixed tube, the upper end of the fixed tube is fixedly connected to a flange, the upper ends of the two fixed tubes are commonly fixedly connected to an air collecting box, the upper end of the air collecting box is fixedly connected to a supporting paper board, the upper end of the supporting paper board is cut with a plurality of accommodating grooves, a wear-resistant nylon wheel is rotatably connected in the accommodating groove, the front end of the supporting paper board is fixedly connected to a plurality of mounting blocks, a mounting rod is fixedly connected between two adjacent mounting blocks, and a surface sleeve of the mounting rod is rotatably provided with Two wear-resistant nylon wheels are provided, and multiple ventilation holes are carved on the upper end of the supporting paper board. An adjusting block is provided on the inner wall of the fixed tube, and an adjusting groove is carved through the surface of the adjusting block. An accommodating tube is provided in the inner cavity of the fixed tube, and the accommodating tube is located below the adjusting block. The outer surface of the accommodating tube is fixedly connected to two fixing rods, and the ends of the two fixing rods away from each other are fixedly connected to the inner wall of the fixed tube. An electric push rod is fixedly connected to the inner bottom wall of the accommodating tube, and the upper end of the electric push rod is fixedly connected to a slide plate, and the inner top wall of the accommodating tube is fixedly connected to a compression spring, and the upper end of the slide plate is fixedly connected to an adjusting rod, and the upper end of the adjusting rod moves in turn through the compression spring and the accommodating tube and is fixedly connected to a shielding ball, and the shielding ball is located in the adjusting groove.

[0006] In the above-mentioned suspended air blowing separation device, when blowing heavier or larger quantities of corrugated paper, there is no need to increase the wind force of the blower. Instead, the electric push rod drives the shielding ball to move up and down to block the diameter of the adjustment slot, thereby changing the size of the gap between the shielding ball and the diameter of the adjustment slot. The air pressure generated by the airflow through gaps of different sizes is also different, thereby achieving the effect of separating corrugated paper of different thicknesses and quantities from the paper feeding mechanism, thereby effectively reducing the power consumption of the blower.

[0007] As a further improvement of the present application, the longitudinal section of the adjustment groove is in the shape of an isosceles trapezoid, and the lower diameter of the adjustment groove is larger than the upper diameter.

[0008] As a further improvement of the present application, the diameter of the shielding ball is smaller than the upper diameter of the adjustment groove, and the shielding ball is made of steel.

[0009] As a further improvement of the present application, the outer surface of the slide is fitted with the inner wall of the accommodating tube, the lower end of the compression spring is fixedly connected to the upper end of the slide, and the diameter of the accommodating tube is smaller than the diameter of the shielding ball.

[0010] As another improvement of the present application, a wind pressure sensor is fixedly connected to the lower end of the paper support plate, and the wind pressure sensor and the electric push rod are both connected to the external controller signal.

[0011] To sum up, in actual application, after the blower is started, the electric push rod can be started to extend, thereby driving the slide plate and the adjusting rod to move upward, causing the shielding ball to move upward, and narrowing the gap between the shielding ball and the upper diameter of the adjusting slot. After the airflow enters the fixed tube, it is blown to the corrugated paper at the upper end of the paper feeding mechanism through the gap between the shielding ball and the adjusting slot. The air pressure generated by the airflow through gaps of different sizes is also different, which makes it easy to separate corrugated paper of different thicknesses and quantities from the paper feeding mechanism, so that the corrugated paper is in a slightly suspended state. The wind force can be changed without adjusting the wind force of the blower, thereby effectively reducing the power consumption of the blower. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method:

[0023] Figure 1 and Figure 2 Shown: a suspended air blowing separation device, including a blower 1 and a mounting tube 2 fixedly connected to the air outlet of the blower 1. Those skilled in the art can select a suitable model of blower 1 according to actual needs, for example: 2HG220. Two telescopic hoses 3 are fixedly connected to the outer surface of the mounting tube 2. The telescopic hose 3 facilitates the movement of the fixed tube 4 with the movement of the paper feeding mechanism. The end of the telescopic hose 3 away from the mounting tube 2 is fixedly connected to the fixed tube 4. The upper end of the fixed tube 4 is fixedly connected to a flange 5. The flange 5 facilitates the installation and fixing of the fixed tube 4 and the paper feeding mechanism. The upper ends of the two fixed tubes 4 are fixedly connected to an air collecting box 16. The air collecting box The upper end of 16 is fixedly connected to a supporting paper board 17, which is a mirror-polished steel plate. A plurality of accommodating grooves are cut on the upper end of the supporting paper board 17, and a wear-resistant nylon wheel 18 is rotatably connected in the accommodating groove. The front end of the supporting paper board 17 is fixedly connected to a plurality of mounting blocks, and a mounting rod 19 is fixedly connected between two adjacent mounting blocks. Two wear-resistant nylon wheels 20 are rotatably sleeved on the surface of the mounting rod 19. The outer surfaces of the wear-resistant nylon wheels 18 and 20 are located above the supporting paper board 17, which is convenient for conveying corrugated paper. A plurality of ventilation holes are cut on the upper end of the supporting paper board 17. After the gas enters the interior of the gas collecting box 16, it is blown toward the corrugated paper through the ventilation holes.

[0024] Figure 3 、 Figure 4 、 Figure 5 and Figure 6It is shown that: the inner wall of the fixed tube 4 is provided with an adjusting block 6, and the surface of the adjusting block 6 is penetrated by an adjusting groove 7. The longitudinal section of the adjusting groove 7 is an isosceles trapezoidal shape, and the lower diameter of the adjusting groove 7 is larger than the upper diameter, which is convenient for the entry and discharge of airflow. The inner cavity of the fixed tube 4 is provided with a accommodating tube 8, and the accommodating tube 8 is located below the adjusting block 6. The outer surface of the accommodating tube 8 is fixedly connected to two fixing rods 9, and the ends of the two fixing rods 9 that are away from each other are fixedly connected to the inner wall of the fixed tube 4. The fixing rods 9 can install and fix the accommodating tube 8. The inner bottom wall of the accommodating tube 8 is fixedly connected to an electric push rod 10. Those skilled in the art can select a suitable model of the electric push rod 10 according to actual needs, for example: MI10-25SCA. The upper end of the electric push rod 10 is fixedly connected to a slide plate 11, and the inner top wall of the accommodating tube 8 is fixedly connected to a compression spring 12. The compression spring 12 The lower end is fixedly connected to the upper end of the skateboard 11, and the compression spring 12 can dissipate the slight shaking caused by the airflow blowing the shielding ball 14, effectively extending the service life of the shielding ball 14 and the electric push rod 10. The outer surface of the skateboard 11 fits into the inner wall of the accommodating tube 8, and the upper end of the skateboard 11 is fixedly connected to the adjusting rod 13. The upper end of the adjusting rod 13 moves through the compression spring 12 and the accommodating tube 8 in turn and is fixedly connected to the shielding ball 14. The shielding ball 14 is located in the adjusting groove 7. The diameter of the shielding ball 14 is smaller than the upper diameter of the adjusting groove 7. The shielding ball 14 is made of steel. The diameter of the accommodating tube 8 is smaller than the diameter of the shielding ball 14. The extension and retraction of the electric push rod 10 can drive the skateboard 11 and the adjusting rod 13 to move longitudinally, thereby driving the shielding ball 14 to move up and down, thereby adjusting the size of the gap between the shielding ball 14 and the upper diameter of the adjusting groove 7.

[0025] During use, after the blower 1 is started, the electric push rod 10 can be started to extend, thereby driving the slide plate 11 and the adjusting rod 13 to move upward, so that the shielding ball 14 moves upward, and the gap between the shielding ball 14 and the upper diameter of the adjusting slot 7 becomes narrower. After the airflow enters the fixed tube 4, it is blown toward the corrugated paper at the upper end of the paper feeding mechanism through the gap between the shielding ball 14 and the adjusting slot 7. The air pressure generated by the airflow through gaps of different sizes is also different, which makes it easy to separate corrugated paper of different thicknesses and quantities from the paper feeding mechanism, so that the corrugated paper is in a slightly suspended state, so that the subsequent paper feeding mechanism can transport the corrugated paper. The wind force can be changed without adjusting the wind force of the blower 1, thereby effectively reducing the power consumption of the blower 1.

[0026] Second implementation method:

[0027] This embodiment is based on the first embodiment, and a wind pressure sensor 15 is added. The rest of the parts remain the same as the first embodiment.

[0028] Figure 7It is shown that a wind pressure sensor 15 is fixedly connected to the lower end of the paper support plate 17. Those skilled in the art can select a suitable model of wind pressure sensor 15 according to actual needs, for example: QDX50D. The wind pressure sensor 15 and the electric push rod 10 are both connected to the external controller signal.

[0029] During use, the wind pressure sensor 15 can monitor the wind pressure in the fixed pipe 4 in real time, so that the staff can adjust the height of the shielding ball 14 and use it conveniently.

[0030] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
