However, the straws need to be transported to the packaging device after production is completed, and the existing ones are basically transported manually. In addition, the straws usually need to be disinfected before packaging, and manual transportation is also adopted in the process of transporting the straws to the disinfection device, which makes this process time-consuming, labor-intensive and inefficient. Summary of the invention

The straws then enter the rotating assembly, and then the controller controls the rotating assembly to start. While the rotating assembly drives the straws to rotate and transport, the rotating assembly disinfects and performs surface inspection on the straws, so that the straws are disinfected and their surface is inspected for damage during the transportation process, thereby saving the straw production and transportation process and improving the yield rate of the straws in subsequent packaging.

[0005] Preferably, suspension boards are symmetrically arranged on both sides of the machine body, the suspension boards are connected to the machine body via a support frame, and legs are arranged on the suspension boards for support.

[0006] Preferably, the rotating assembly includes: a rotating chamber, the rotating chamber is arranged in the body, a rotating column is arranged in the rotating chamber, the rotating column is rotatably connected to the rotating chamber, conveying plates are symmetrically arranged on both sides of the rotating column, a motor is arranged in the suspension plate, and the driving shaft of the motor is connected to the conveying plate.

[0007] Preferably, a plurality of rotating grooves are provided on the rotating column, and the plurality of rotating grooves are arranged around the axis of the rotating column. An ultraviolet light source and a detector are provided on the inner wall of the rotating groove, and the rotating groove is used for placing a straw.

[0008] Preferably, a plurality of movable grooves are provided on the conveying plate, and the plurality of movable grooves are arranged around the axis of the conveying plate. An extrusion column is provided on the movable groove, and a spring is provided between the extrusion column and the rotating column. The extrusion column is slidably connected to the movable groove, and the extrusion column corresponds to the rotating groove one by one.

[0009] Preferably, an air storage chamber is provided inside the rotating column, the air storage chamber is filled with ozone, an air delivery channel is provided inside the conveying plate, an air pump is provided inside the air storage chamber, and the air pump is connected to the air delivery channel through a pipeline.

[0010] Preferably, an output port is provided on one side of the extrusion column close to the rotating groove, the output port is connected to the air supply channel through a telescopic tube, the diameter of the output port is smaller than the inner diameter of the straw, and a rubber pad is also provided on one side of the extrusion column close to the rotating groove.

[0011] Preferably, a protrusion is provided on a side of the suspension plate close to the rotating column, and a side of the extrusion column away from the rotating column is slidably connected to the suspension plate.

[0012] Preferably, a plurality of guide rods are provided inside the funnel cavity, and the guide rods are equidistantly arranged along the side of the funnel cavity, and the distance between the top of the guide rods and the bottom of the funnel cavity decreases from the edge of the funnel cavity to the center of the funnel cavity.

[0013] First, the straw is transported to the funnel cavity. Since a number of guide rods are arranged in the funnel cavity, the straw enters the gap between two adjacent guide rods, so that the straw is transported to the feed port in an orderly manner, avoiding the dislocation of the straw during the movement, thereby blocking the feed port and affecting the normal transportation of the straw, thus ensuring the stable operation of the equipment; When the straw is transported to the rotating chamber through the feed port, one of the rotating grooves is connected to the feed port, and the straw falls into the rotating groove. Then the controller controls the motor to start, and the driving shaft of the motor drives the conveying plate to rotate. During the rotation of the conveying plate, the rotating column is driven to rotate, and the rotating column drives the rotating groove to rotate. When the rotating groove rotates, the straw moves, and the rotating groove drives the straw to rotate toward the side close to the discharge port. When the rotating groove drives the straw to rotate, the next rotating groove will be connected to the feed port. Through the rotation of the rotating column, the straws enter the rotating grooves one by one, realizing the continuous conveying of the straws. When the conveying plate rotates, it drives the moving groove to rotate, and the moving groove drives the squeezing column to rotate, so that the squeezing column and the rotating groove rotate synchronously. Since a protrusion is provided on the side of the suspension plate close to the rotating column, the squeezing column slides on the surface of the suspension plate around the axis of the suspension plate when it rotates. When the squeezing column encounters the protrusion during the sliding process, the protrusion squeezes the squeezing column, so that the squeezing column moves to the side close to the rotating groove. The diameter of the output port is smaller than the inner diameter of the straw. The output port extends into the inner cavity of the straw under the action of the squeezing column. Since a rubber pad is also provided on the side of the squeezing column close to the rotating groove, both ends of the straw are blocked by the rubber pad, so that the inner cavity of the straw is in a closed state. When the straw rotates toward the discharge port, the controller controls the ultraviolet light source in the rotating tank to start, and the ultraviolet light source immediately irradiates the outer surface of the straw to disinfect the outer surface of the straw. At the same time, the controller also controls the air pump in the air storage chamber to start, and the air pump extracts ozone in the air storage chamber, and transports it to the air delivery channel in the conveying plate through the pipeline, and then transports it to the output port through the air delivery channel through the telescopic tube, and then the ozone flows in the inner cavity of the straw, and then the ozone disinfects the inner cavity of the straw. Through the cooperation of the ultraviolet light source and the ozone, the outer side and the inner cavity of the straw are disinfected synchronously, thereby improving the efficiency of straw disinfection; During the process of straw disinfection, the detector in the rotating tank always detects the light intensity emitted by the ultraviolet light source in the rotating tank. If the surface of the straw is damaged, the inner cavity of the straw will be in a connected state with the rotating tank, and then the ozone flowing in the inner cavity of the straw will leak into the rotating tank through the damaged part of the straw, and then the ozone will absorb the ultraviolet light, and then the light intensity of the ultraviolet light in the rotating tank will be disturbed. The detector converts the light intensity signal into an electrical signal and rotates it to the controller, and the controller analyzes the electrical signal. If the light intensity of the ultraviolet light in the rotating tank changes, the surface of the straw is damaged. If the light intensity of the ultraviolet light in the rotating tank does not change significantly, the surface of the straw is not damaged. Through the characteristic of ozone absorbing ultraviolet light, the effect of detecting damage on the surface of the straw is achieved during the process of ozone and ultraviolet light disinfection of the straw, which further saves the process of straw transportation, thereby improving the efficiency of straw production and manufacturing, and ensuring the yield rate of the straw when it is output; When the rotating groove drives the straw to move to the discharge port, the extrusion column is separated from the protrusion, and then the extrusion column moves to the side away from the rotating column, so that the output port is separated from the inner cavity of the straw, and then the straw moves from the rotating groove to the discharge port for output.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. If the surface of the straw is damaged, the inner cavity of the straw will be connected to the rotating groove, and the ozone flowing in the inner cavity of the straw will leak into the rotating groove through the damaged part of the straw, and the ozone will absorb ultraviolet light, and the light intensity of the ultraviolet light in the rotating groove will be disturbed. The detector converts the light intensity signal into an electrical signal and rotates it to the controller. The controller analyzes the electrical signal. If the light intensity of the ultraviolet light in the rotating groove changes, the surface of the straw is damaged. If the light intensity of the ultraviolet light in the rotating groove does not change significantly, the surface of the straw is not damaged. Through the characteristic of ozone absorbing ultraviolet light, in the process of disinfecting the straw with ozone and ultraviolet light, the effect of detecting damage on the surface of the straw is achieved, which further saves the process of straw transportation, thereby improving the efficiency of straw production and manufacturing, and ensuring the yield rate of the straw during output.

[0026] As a specific embodiment of the present invention, a plurality of guide rods 15 are arranged inside the funnel cavity 11, and the plurality of guide rods 15 are arranged equidistantly along the side of the funnel cavity 11, and the distance between the top of the guide rods 15 and the bottom of the funnel cavity 11 decreases from the edge of the funnel cavity 11 to the center of the funnel cavity 11.

[0027] Working principle of the present invention: First, the straw is transported to the funnel cavity 11. Since a plurality of guide rods 15 are provided in the funnel cavity 11, the straw enters the gap between two adjacent guide rods 15, so that the straw is transported to the feed port 12 in an orderly manner, thereby preventing the straw from being misplaced during the movement, thereby blocking the feed port 12 and affecting the normal transportation of the straw. When the straw is transported to the rotating chamber 21 through the feed port 12, one of the rotating grooves 24 is connected to the feed port 12, and the straw falls into the rotating groove 24. Then the controller controls the motor to start, and the driving shaft of the motor drives the conveying plate 23 to rotate. During the rotation of the conveying plate 23, the rotating column 22 is driven to rotate, and the rotating column 22 drives the rotating groove 24 to rotate. When the rotating groove 24 rotates, the straw moves, and the rotating groove 24 drives the straw to rotate toward the side close to the discharge port 13. When the rotating groove 24 drives the straw to rotate, the next rotating groove 24 will be connected to the feed port 12, and the straws will enter the rotating grooves 24 one by one through the rotation of the rotating column 22, so that the straws can be continuously transported; When the conveying plate 23 rotates, it drives the moving groove to rotate, and the moving groove drives the squeezing column 25 to rotate, so that the squeezing column 25 and the rotating groove 24 rotate synchronously. Since a protrusion 141 is provided on the side of the suspension plate 14 close to the rotating column 22, the squeezing column 25 slides on the surface of the suspension plate 14 around the axis of the suspension plate 14 when rotating. When the squeezing column 25 encounters the protrusion 141 during the sliding process, the protrusion 141 squeezes the squeezing column 25, so that the squeezing column 25 moves to the side close to the rotating groove 24. The diameter of the output port 251 is smaller than the inner diameter of the straw. The output port 251 extends into the inner cavity of the straw under the action of the squeezing column 25. Since a rubber pad is also provided on the side of the squeezing column 25 close to the rotating groove 24, both ends of the straw are blocked by the rubber pad, so that the inner cavity of the straw is in a closed state. When the straw rotates toward the discharge port 13, the controller controls the ultraviolet light source in the rotating groove 24 to start, and the ultraviolet light source immediately irradiates the outer surface of the straw to disinfect the outer surface of the straw. At the same time, the controller also controls the air pump in the air storage chamber 26 to start, and the air pump extracts ozone in the air storage chamber 26, and transports it to the air delivery channel in the conveying plate 23 through the pipeline, and then transports it to the output port 251 through the air delivery channel through the telescopic tube, and then the ozone flows in the inner cavity of the straw, and then the ozone disinfects the inner cavity of the straw. Through the cooperation of the ultraviolet light source and the ozone, the outer side and the inner cavity of the straw are disinfected synchronously; During the process of straw disinfection, the detector in the rotating groove 24 always detects the light intensity emitted by the ultraviolet light source in the rotating groove 24. If the surface of the straw is damaged, the inner cavity of the straw will be in a connected state with the rotating groove 24, and then the ozone flowing in the inner cavity of the straw will leak into the rotating groove 24 through the damaged part of the straw, and then the ozone will absorb the ultraviolet light, and then the light intensity of the ultraviolet light in the rotating groove 24 will be disturbed. The detector converts the light intensity signal into an electrical signal and rotates it to the controller, and the controller analyzes the electrical signal. If the light intensity of the ultraviolet light in the rotating groove 24 changes, the surface of the straw is damaged. If the light intensity of the ultraviolet light in the rotating groove 24 does not change significantly, the surface of the straw is not damaged. Through the characteristic of ozone absorbing ultraviolet light, the effect of detecting damage on the surface of the straw is achieved during the process of ozone and ultraviolet light disinfection of the straw. When the rotating groove 24 drives the straw to move to the discharge port 13, the squeezing column 25 is disengaged from the protrusion 141, and then the squeezing column 25 moves to the side away from the rotating column 22, so that the output port 251 is disengaged from the inner cavity of the straw, and then the straw moves from the rotating groove 24 to the discharge port 13 for output.
