Description
Technical Field
[0001] The utility model relates to the technical field of tobacco machinery and equipment, in particular to a flow guiding device at a vibration conveying end before shredding. Background Art
[0002] The shredder is an important equipment in the shredder production line. It is used to make tobacco leaves into shredded tobacco that meets the process requirements. Metal detectors are widely used in front of the shredder. Metal detectors can detect metal debris in tobacco leaves and effectively remove them, thereby improving the purity of tobacco leaves. The metal detector is installed above the vibrating conveyor before shredding. When the metal detector detects that there are metal debris in the tobacco leaves passing below it, the unloading baffle of the vibrating conveyor opens downward, allowing the impure tobacco leaves to fall into the storage device from the outlet at the unloading baffle, preventing metal debris from entering the shredder and causing failures such as knife breakage. According to actual work, the width of the discharge baffle of the vibrating conveyor is smaller than the width of the vibrating conveyor. It is very likely that the impure tobacco leaves will bypass the discharge baffle from the side of the vibrating conveyor and enter the shredder. In order to ensure that all the impure tobacco leaves are removed, fixed guide plates are often installed on both sides of the conveying channel of the vibrating conveyor, so that the tobacco leaves pass above the discharge baffle. However, due to the fixed guide plates on both sides of the vibrating conveyor, the width of the vibrating conveyor becomes narrower and the material is not easy to pass through. If the production flow increases, it is very easy to cause blockage and flow interruption here. Especially in summer, when the ambient temperature and humidity are high, the moisture in the material increases relatively, the adhesion increases, and the risk of blockage and shutdown also increases accordingly.

[0024] like Figures 1 to 4 As shown, the utility model provides a flow guide device for the vibrating conveying end before cutting.
[0025] It includes a vibrating conveying channel 1 and a guide device 2 symmetrically arranged on the left and right side walls thereof, the guide device 2 includes a rotating shaft 201 and a fixed plate 202 sleeved on the outside thereof, a threaded hole 203 is provided on the surface of the fixed plate 202, the upper and lower ends of the rotating shaft 201 are respectively connected with a fixed sleeve plate I 204 and a fixed sleeve plate II 205, the side ends of the fixed sleeve plate I 204 and the fixed sleeve plate II 205 are commonly connected with a guide plate 206, the rotating shaft 201 is connected with a rotating cylinder through a cylinder hole 207 opened at the top thereof, and the rotating cylinder is fastened to the rotating shaft 201 by a top screw, the bottom surface of the vibrating conveying channel 1 is provided with a feed opening 4 and a limiting column 3, and the feed opening 4 is provided with a feed opening baffle;
[0026] In the embodiment of the utility model, the fixing plate 202 is sleeved on the middle outer wall surface of the rotating shaft 201, and the rotating shaft 201 can rotate relative to the fixing plate 202. The threaded holes 203 are evenly arranged at the left and right ends of the fixing plate 202. The fixing plate 202 is fixed to the side wall surface of the vibration conveying channel 1 by the cooperation of the screws and the threaded holes 203, and then the guide device 2 is installed at the corresponding position of the side wall surface of the vibration conveying channel 1;
[0027] In the embodiment of the utility model, the fixed sleeve plate I 204 and the fixed sleeve plate II 205 are respectively fixedly connected to the upper and lower ends of the rotating shaft 201, and the side end face and the bottom end face of the fixed sleeve plate I 204, and the side end face and the top end face of the fixed sleeve plate II 205 are respectively fixedly connected to the guide plate 206, and there is a gap between the middle side end of the guide plate 206 and the fixed plate 202. The setting of the gap can ensure that the rotating shaft 201 rotates relative to the fixed plate 202 and then drives the guide plate 206 to rotate more smoothly through the fixed sleeve plate I 204 and the fixed sleeve plate II 205, so as to avoid the middle side end of the guide plate 206 from contacting with the surface of the fixed plate 202 and getting stuck;
[0028] In the embodiment described in the utility model, the rotary cylinder has the function of driving the rotating shaft 201 to rotate. The rotary cylinder includes a cylinder body end and a rotary piston end. A top screw hole 208 penetrating the cylinder hole 207 is provided on the side of the fixed sleeve plate I 204. The rotary piston end of the rotary cylinder penetrates the cylinder hole 207 and is fastened to the top of the rotating shaft 201 in cooperation with the top screw and the top screw hole 208, ensuring that the rotary piston end of the rotary cylinder rotates synchronously with the rotating shaft 201.

[0029] In the embodiment described in the utility model, the feed opening 4 is located behind the guide device 2, and the feed opening baffle can be controlled to flip so that the feed opening 4 is opened and connected with the vibration conveying channel 1; it should be noted that the mechanism component for controlling the flipping of the feed opening baffle belongs to the prior art and does not belong to the scope of protection of the invention;
[0030] In the embodiment described in the utility model, the limiting column 3 has the function of limiting the rotation angle of the flow guide device 2 relative to the side wall of the vibrating conveying channel 1. The limiting column 3 is located on the rotation trajectory of the end of the flow guide device 2 away from the rotating shaft 201. When the rotating cylinder drives the flow guide device 2 to rotate toward the inside of the vibrating conveying channel 1, the limiting column 3 blocks the flow guide device 2 from continuing to rotate, so that the opposite surfaces of the flow guide device 2 symmetrically arranged on the left and right side walls of the vibrating conveying channel 1 form a discharge channel that can just allow the impurity-containing materials to smoothly enter the discharge port 4, ensuring that the impurity-containing materials fall from the discharge channel through the discharge port 4 into the storage device located below the discharge port 4, thereby avoiding the impurity-containing materials from entering the next process equipment and causing damage to it;
[0031] In the embodiment described in the utility model, a metal detector is arranged above the vibrating conveying channel 1, and the metal detector is located in front of the guide device 2. The metal detector can detect whether there are metal debris in the material passing thereunder, and the metal detector is electrically connected to the rotating cylinder. The rotating cylinder controls the rotation movement through an external solenoid valve and an air source. When the metal detector detects the presence of metal debris in the material passing thereunder, the metal detector sends an electrical signal to the solenoid valve to control the compressed gas to enter the rotating cylinder, thereby causing the rotating piston end of the rotating cylinder to rotate and simultaneously driving the guide device 2 to rotate toward the inner side of the vibrating conveying channel 1.
[0032] In combination with the above content, the working principle of the utility model is:
[0033] During shutdown and normal production, that is, when the material does not contain metal impurities, the symmetrically arranged flow guide device 2 is in a state of being close to the left and right side walls of the vibrating conveying channel 1, and the material is transported to the next process equipment through the vibrating conveying channel 1. When the metal detector detects the presence of metal impurities in the material passing below it, the material discharge baffle plate flips to open the material discharge port 4 and connect it to the vibrating conveying channel 1. At the same time, the metal detector sends an electrical signal to the solenoid valve to control the compressed gas to enter the rotating cylinder, thereby causing the rotating piston end of the rotating cylinder to rotate and simultaneously drive the rotating shaft 201 fastened thereto to rotate in the same direction. The rotating action of the rotating shaft 201 drives the fixed sleeve plate I 204, the fixed sleeve plate II 205 and the flow guide plate 20 connected to the rotating shaft 201. 6 can rotate toward the inside of the vibrating conveying channel 1 with the rotating shaft 201 as the center at the side end of the vibrating conveying channel 1. When the guide device 2 rotates a certain angle relative to the side wall of the vibrating conveying channel 1, the limiting column 3 blocks the guide device 2 from continuing to rotate, so that the opposite surfaces of the guide device 2 symmetrically arranged on the left and right side walls of the vibrating conveying channel 1 form a discharge channel that can just allow the impurity-containing materials to smoothly enter the discharge port 4, ensuring that the impurity-containing materials fall from the discharge channel through the discharge port 4 into the storage device located below the discharge port 4. After a certain delay, the discharge baffle is flipped again to close the discharge port 4, and at the same time, the rotating cylinder drives the guide device 2 to reset, and normal tobacco leaves continue to pass through the surface of the vibrating conveying channel 1 and go to the next process equipment in parallel.
