[0023] like Figs. 1 to 4 As shown, the present invention provides a novel feed hopper guide plate for a shredder.
[0024] It includes a shredder hopper 11, with a shredder support frame at the top of the hopper 11. Two guide plates are symmetrically arranged inside the hopper 11. A rotating shaft 5 is located at the top of the guide plates. A planar mounting position 9 is provided at the center of the surface of the rotating shaft 5. The length of the planar mounting position 9 on the surface of the rotating shaft 5 is equal to the width of the guide plate. The top of the guide plate is fastened to the planar mounting position 9 of the rotating shaft 5 with screws. The front and rear ends of the rotating shaft 5 are respectively connected to fixed supports 4 through transmission bearings 8. The fixed supports 4 are configured with a stepped structure and are fixed to the top of the shredder support frame by pins. A rotating cylinder 6 is connected to one end of the rotating shaft 5, and the rotating cylinder 6 is connected to an external air source.
[0025] In the embodiments of the present invention, the guide plate includes an upper guide plate 1 and a lower guide plate 3 connected to its bottom end by a hinge 2. The upper guide plate 1 is configured as a flat plate structure. The width of the upper guide plate 1 is equal to the distance between the front and rear side walls of the inner side wall of the shredder hopper 11, so that the side end face of the upper guide plate 1 can be completely fitted with the inner wall surface of the shredder hopper 11. This avoids the situation where smoke and dust enter between the side end face of the guide plate and the inner wall surface of the shredder hopper 11, thus preventing the growth of smoke insects and increasing the quality risk. It also further reduces the frequency and intensity of maintenance by operators.
[0026] In the embodiments described in this invention, the lower guide plate 3 hangs freely relative to the upper guide plate 1 inside the feed hopper 11 of the shredder.
[0027] In the embodiments of the present invention, a plurality of threaded holes 10 are evenly distributed on the surface of the planar mounting position 9. The length of the planar mounting position 9 on the surface of the rotating shaft 5 is equal to the width of the guide plate, so that the top end of the upper guide plate 1 can just fit against the planar mounting position 9, so that the upper guide plate 1 can be fastened to the middle position of the rotating shaft 5 with the cooperation of the threaded holes 10 and screws, and avoid the rotating shaft 5 from displacing the guide plate during the rotation process, which would affect the feeding effect of the shredder.
[0028] Specifically, there are two rotating shafts 5, which are symmetrically arranged above the shredder support frame. The planar mounting positions 9 on the surfaces of the two rotating shafts 5 are opposite to each other. The two rotating shafts 5 have the same rotation angle range and opposite rotation directions. Under the action of the rotating cylinder 6, the two rotating shafts 5 can move synchronously, so that the two rotating shafts 5 drive the two guide plates to move closer or further away from each other. There are six threaded holes 10.
[0029] In the embodiments of the present invention, the surface of the fixed support 4 is provided with pin holes 7. With the cooperation of the pin holes 7 and the pin shaft, the fixed supports 4 located at the front and rear ends of the rotating shaft 5 are symmetrically fastened to the upper surfaces of the front and rear ends of the shredder support frame. The fixed supports 4 are arranged at a distance away from the end side of the shredder support frame, so that there is a gap between the guide plate and the left and right side walls of the shredder hopper 11, so as to provide a sufficiently wide rotation angle range when the rotating shaft 5 drives the guide plate to rotate.
[0030] Specifically, the number of fixed supports 4 is set to four, and each fixed support 4 has two pin holes 7 on its surface.
[0031] In the embodiments described in this invention, the rotary cylinder 6 provides rotational power to the rotary shaft 5. Under the action of an external air source, the rotary cylinder 6 can control the rotary shaft 5 to rotate forward and backward at a certain angle according to the actual needs of the production process. This, in turn, controls the upper guide plate 1 to rotate at a corresponding angle towards the inner and outer sides of the shredder hopper 11. This achieves the purpose of accurately determining the rotation angle of the guide plate by adjusting the rotation angle of the rotary shaft 5, thereby controlling the opening and closing degree between the two guide plates symmetrically arranged inside the shredder hopper 11. This ensures that the incoming tobacco leaves at different temperatures can pass through the two guide plates symmetrically arranged inside the shredder hopper 11 uniformly and without voids, so as to smoothly form a solid tobacco cake, ensuring the feeding effect of the shredder and improving the subsequent shredding quality.
[0032] Specifically, in the actual production process, the feeding status of the feed hopper 11 of the shredder will change with the temperature of the incoming tobacco leaves. When the temperature of the incoming tobacco leaves is higher than the preset temperature, the amount of incoming tobacco leaves fed needs to be increased. When the temperature of the incoming tobacco leaves is lower than the preset temperature, the amount of incoming tobacco leaves fed needs to be reduced to ensure that a solid tobacco cake is formed smoothly and that the subsequent shredding effect is not affected.
[0033] Based on the above, the specific operating steps of this utility model include:
[0034] Step S1: Pre-production preparation
[0035] Before the production process begins, the rotary cylinder 6 is controlled by an external air source to operate according to the different cigarette brands and formula characteristics. The rotary cylinder 6 controls the two guide plates symmetrically arranged inside the feed bin 11 of the shredder to rotate at a certain angle through the rotary shaft 5, so as to ensure that the two guide plates are in the predetermined initial position before the production begins.
[0036] Step S2: Production in Progress
[0037] During production, the feeding status of the shredder hopper 11 changes with the temperature of the incoming tobacco leaves. When the temperature of the incoming tobacco leaves is higher than the preset temperature, it is necessary to increase the feeding amount. This is achieved by controlling the rotary cylinder 6 through an external air source. The rotary cylinder 6 controls the rotating shaft 5 to rotate at a certain angle, thereby causing the two guide plates symmetrically arranged inside the shredder hopper 11 to rotate simultaneously towards the outside of the shredder hopper 11, thus increasing the feeding amount. When the temperature of the incoming tobacco leaves is lower than the preset temperature, it is necessary to reduce the feeding amount. This is also achieved by controlling the rotary cylinder 6 through an external air source. The rotary cylinder 6 controls the rotating shaft 5 to rotate at a certain angle, thereby causing the two guide plates symmetrically arranged inside the shredder hopper 11 to rotate simultaneously towards the inside of the shredder hopper 11, thus reducing the feeding amount.
[0038] Step S3: After production is completed
[0039] After the production process in step S2 is completed, the rotary cylinder 6 is controlled by an external air source to rotate the rotary shaft 5 back to the initial angle, thereby restoring the two guide plates symmetrically arranged inside the shredder hopper 11 to the predetermined initial position, thus completing the entire production process.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
