Description

Technical Field

[0001] The utility model relates to the technical field of tobacco material processing equipment, and more specifically, to a tobacco stem air separator rotating net cleaning device. Background Art

[0002] Although brush rollers continuously clean the outer circumference of the screens used in tobacco stem winnowing machines in the tobacco-making workshop, mesh clogging is inevitable. This clogged mesh reduces the wind speed within the winnowing machine, compromising the overall dust removal performance. Utility Model Content

[0003] One purpose of the present invention is to provide a new technical solution for a tobacco stem air separator rotary screen cleaning device to solve the problems raised in the above-mentioned background technology.

[0004] According to a first aspect of the present invention, a tobacco stem air separator rotary screen cleaning device is provided, comprising an air duct, a rotary screen body, and a rotary screen support frame;

[0005] A connecting ring is provided at the outlet of the air duct, and the rotating net support frame is composed of a plurality of support rods in a ring array, and the rotating net body is sleeved on the outside of the support rods; one end of the support rod is connected to the rotating ring, and the inner side of the rotating ring and the outer side of the connecting ring are both provided with slides, and the slides are connected by ball sliding; the other end of the support rod is bent inward and connected to a connecting plate, and a connecting hole is provided in the center of the connecting plate, and the connecting hole is used to connect the rotating net motor to drive the rotating net support frame and the rotating net body to rotate;

[0006] A compressed air reflection plate is further provided on the side of the connecting plate facing the air duct, and the compressed air reflection plate can reflect the compressed air in the air duct to the rotating net body.

[0007] Optionally, according to the tobacco stem air separator rotary net cleaning device described in the present invention, the side of the compressed air reflection plate facing the air duct is an annular groove structure, and the groove of the compressed air reflection plate has an uneven arc surface structure.

[0008] Optionally, according to the tobacco stem air separator rotary net cleaning device described in the utility model, the air outlet of the air duct is sealed and provided with a direct blowing pipe, and the direct blowing pipe extends to the groove of the compressed air reflection plate.

[0009] Optionally, according to the tobacco stem air separator rotary net cleaning device described in the utility model, an opening and closing angle actuator is provided in the air duct, and the opening and closing angle actuator is connected to the straight blowing pipe.

[0010] Optionally, according to the tobacco stem air separator rotary net cleaning device described in the present invention, the outer side of the air duct is also connected to an air bag through a compressed air pipeline to increase the wind force of the direct blowing pipe blowing toward the compressed air reflection plate.

[0011] Optionally, according to the tobacco stem air separator rotary net cleaning device described in the utility model, a solenoid valve is also provided on the compressed air pipeline.

[0012] The utility model is designed with a compressed air reflector plate, so that the compressed air that extends into the interior of the rotating net can be reflected by the compressed air reflector and blown to the proximal and distal cylindrical surfaces of the rotating net. Furthermore, the arc surface of the compressed air reflector is irregularly set, so that the rotating net speed increases the compressed air blowing speed, increasing the compressed air reflection speed. At the same time, on the basis of air bag pressurization, the compressed air blowing force is further increased, thereby strengthening the cleaning force of the rotating net surface. The use of compressed air positive pressure to clean the rotating net mesh inside the rotating net avoids the existing design of using a brush roller to continuously clean the outer circumference of the rotating net, thereby avoiding the mesh clogging phenomenon caused by the use of a brush roller.

DETAILED DESCRIPTION

[0019] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0020] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0021] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0022] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0023] according to Figure 1 and Figure 2 As shown, the utility model provides a tobacco stem air separator rotary net cleaning device, comprising an air duct 1, a rotary net body 2 and a rotary net support frame;

[0024] A connecting ring 3 is provided at the outlet of the air duct 1. The rotary net support frame is composed of a plurality of support rods 8 in a circular array. The rotary net body 2 is sleeved on the outside of the support rods 8. One end of the support rod 8 is connected to the rotating ring 9. The inner side of the rotating ring 9 and the outer side of the connecting ring 3 are both provided with slideways 10. The slideways 10 are connected by ball sliding. The other end of the support rod 8 is bent inward and connected to a connecting plate 11. The center of the connecting plate 11 is provided with a connecting hole. The connecting hole is used to connect the rotary net motor to drive the rotary net support frame and the rotary net body 2 to rotate.

[0025] A compressed air reflection plate 12 is further provided on the side of the connecting plate 11 facing the air duct 1 . The compressed air reflection plate 12 can reflect the compressed air in the air duct 1 to the rotary screen body 2 .

[0026] The rotating net support frame is divided into six equal sections by six brackets. A connecting plate 11 is fixed to one end for mounting on the drive shaft of the rotating net motor. A rotating ring 9 is located at the other end to support the cylindrical rotating net. A number of balls can be placed into the slideway 10 through a pre-set ball loading port. Once loaded, the port can be locked, allowing the balls to roll freely within the slideway 10. After being loaded with balls, the rotating ring 9 mates with the connecting ring 3 on the air duct 1. When the rotating net motor drives the rotating net body 2 to rotate, the balls slide within the slideway 10.

[0027] Furthermore, the side of the compressed air reflector 12 facing the air duct 1 is annularly grooved, with the groove of the compressed air reflector 12 having an uneven, curved surface. The air outlet of the air duct 1 is sealed and equipped with a direct blow pipe 13, which extends to the groove of the compressed air reflector 12. The air bag 5 installed on the compressed air pipeline 4 further increases the compressed air purge force, enhancing the cleaning effect on the rotary screen surface.

[0028] When the screen-rotating motor rotates, the compressed air deflector 12 rotates with it, and compressed air is ejected through a direct blowpipe 13 extending from the deflector 12 to the inlet of the deflector 12. The deflector 12 is designed to have an irregular groove shape. Since the direct blowpipe 13 is fixed in position, the inlet of the deflector 12 remains at the same angle and circle. However, the deflector 12 reflects air at different angles when rotating, allowing the outlet to reach both the proximal and distal cylindrical surfaces of the screen.

[0029] Furthermore, to increase the speed of the net rotation and the compressed air purge, the base of the compressed air reflector 12 can be configured to have a gradually increasing thickness. This allows the compressed air reflector 12 to impart a rotational thrust to air molecules during rotation, increasing the speed of the compressed air reflection. When cleaning the proximal and distal cylindrical surfaces of the net, the rotation speed of the net body 2 can be varied by the net motor, allowing for a combination of slow, meticulous cleaning and fast, powerful cleaning.

[0030] Furthermore, an opening / closing angle actuator 7 is installed within the air duct 1 and connected to the direct blowing pipe 13. As described above, the opening / closing angle actuator 7 is located outside the air duct 1 and is connected to an actuator located inside the air duct 1. The actuator controls the opening and closing of the air duct 1 through the opening / closing angle actuator 7. When cleaning the rotary screen, the actuator closes the air duct 1, creating a relatively sealed space within the rotary screen body 2.

[0031] Furthermore, an air bag 5 is connected to the outside of the air duct 1 via a compressed air pipe 4 to increase the wind force blowing from the direct blow pipe 13 toward the compressed air reflector 12. A solenoid valve 6 is also installed on the compressed air pipe 4. This solenoid valve 6 controls the flow of compressed air within the air bag 5, which increases the compressed air pressure required to clean the rotating screen surface.

[0032] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art will appreciate that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art will appreciate that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
