Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a feeding device for the production of chopped shreds, such as... Figures 1-5 As shown, the feeding device includes a collection box 1, a conveyor belt 2 connected to the top of the collection box 1, a box body 3 with a transparent top and bottom fixedly connected to the top of the collection box 1, a hinged door 4 at the bottom of the box body 3, a spring 5 fixedly connected to the outer wall of the door 4, the end of the spring 5 away from the door 4 fixedly connected to the outer wall of the box body 3, an overlapping block 6 fixedly connected to the outer wall of the door 4, a stirring rod 7 rotatably connected inside the box body 3, a motor 8 for driving the stirring rod 7 to rotate on the outer wall of the box body 3, a cam 9 for squeezing the overlapping block 6 fixedly connected to the outer surface of the stirring rod 7 near the motor 8, and a first transmission belt 10 for driving the stirring rod 7 and the conveyor belt 2.

[0025] Specifically, the motor 8 enables the stirring rod 7 to have a start-stop point of rotation, so that when the cut tobacco is concentrated in the box 3, the motor 8 can be started to drive the output shaft of the motor 8 to rotate the stirring rod 7, so that the stirring rod 7 can stir the cut tobacco in the box 3 to separate the cut tobacco, avoid the cut tobacco from being clumped to affect the mixing effect with the glue, and ensure that the cut tobacco can be mixed with the glue in a one-by-one manner. During the rotation of the stirring rod 7, the first transmission belt 10 drivingly connected thereto can drive the conveying belt 2 to operate, so that the conveying belt 2 is in a feeding state. During the rotation of the stirring rod 7, the cam 9 can be synchronously rotated, so that the cam 9 can extrude the lapping block 6 every time the cam 9 contacts the lapping block 6, so that the lapping block 6 is extruded by the cam 9 to open the switch door 4, so that the separated cut tobacco can fall downward through the switch door 4, so that the cut tobacco can be fed onto the conveying belt 2. When the cam 9 loses the extrusion of the lapping block 6, the switch door 4 can be reset by the elastic adjusting force between the spring 5 and the box 3, so that the switch door 4 is in a closed state. The cut tobacco entering the box 3 is prevented from falling downward through the switch door 4 without being separated, so that each batch of cut tobacco is first separated and then falls downward onto the conveying belt 2 for feeding. The above structure can integrate the feeding and stirring separation of the cut tobacco, so that the production efficiency of the cut tobacco can be effectively improved without using an additional stirring mechanism.

[0026] The top of the collecting box 1 is fixedly connected with a scraper 11 for cleaning the conveying belt 2. The top of the collecting box 1 is rotatably connected with a reciprocating lead screw 12. The reciprocating lead screw 12 is drivingly connected with the conveying belt 2 through a second transmission belt 13.

[0027] The outer surface of the reciprocating lead screw 12 is threadedly connected with a threaded sleeve 14. The outer surface of the threaded sleeve 14 is fixedly connected with a cleaning brush 15 for cleaning the scraper 11.

[0028] Specifically, when the conveying belt 2 is feeding the cut filaments, some cut filaments may adhere to the conveying belt 2, so that the cut filaments adhering to the conveying belt 2 can be scraped off by the scraper 11 when moving to the scraper 11, preventing the cut filaments from adhering to the conveying belt 2 all the time and falling into the collection box 1, facilitating subsequent centralized removal. When the conveying belt 2 is operating, the second transmission belt 13 drivingly connected thereto can drive the reciprocating lead screw 12 to rotate, so that the threaded sleeve 14 threadedly connected thereto can drive the cleaning brush 15 to reciprocate, facilitating the cleaning brush 15 to effectively clean the scraper 11, preventing some cut filaments from adhering to the scraper 11 when the scraper 11 scrapes the cut filaments adhering to the conveying belt 2, affecting the scraping effect of the scraper 11, ensuring the scraping efficiency of the scraper 11, and enabling the scraper 11 to be in a clean state to effectively scrape the cut filaments adhering to the conveying belt 2.

[0029] The collection box 1 is fixedly connected with a limiting rod 16 at the top, and the cleaning brush 15 is slidingly connected to the outer surface of the limiting rod 16.

[0030] Specifically, the limiting rod 16 enables the cleaning brush 15 to have a limiting point, and the sliding of the cleaning brush 15 on the outer surface of the limiting rod 16 also ensures the normal movement of the cleaning brush 15, preventing the threaded sleeve 14 from rotating in place with the reciprocating lead screw 12 when the reciprocating lead screw 12 rotates, thereby causing the cleaning brush 15 to fail to move normally. The threaded sleeve 14 can only move correspondingly by being limited by the limiting rod 16, ensuring that the reciprocating lead screw 12 can drive the cleaning brush 15 to smoothly reciprocate when the threaded sleeve 14 rotates, so that the cleaning brush 15 can smoothly clean the cut filaments adhering to the scraper 11.

[0031] The collection box 1 is fixedly connected with a protective cover 17 at the top, and the reciprocating lead screw 12 is located in the protective cover 17.

[0032] Specifically, the shielding effect of the protective cover 17 enables the falling cut filaments to fall into the collection box 1, avoiding the cut filaments falling on the reciprocating lead screw 12 to cause the reciprocating lead screw 12 to be stuck and fail to rotate normally, so that the reciprocating lead screw 12 can always rotate normally, ensuring that the cleaning brush 15 can clean the cut filaments adhering to the scraper 11.

[0033] The collection box 1 is slidingly connected with a placement block 18 inside, and the outer wall of the collection box 1 is fixedly connected with a discharge plate 19.

[0034] Specifically, the placing block 18 enables the cut filaments falling into the collecting box 1 to be pulled outwards, facilitating subsequent centralized taking out of the cut filaments in the collecting box 1, and the discharging plate 19 enables the cut filaments to be concentrated and discharged, so that the cut filaments on the conveying belt 2 can slide downwards to other production procedures for other processing when the cut filaments move to a certain position, preventing the cut filaments from being scattered randomly.

[0035] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent substitutions or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
