Technical Field

[0001] The utility model relates to the technical field of cigarette manufacturing machinery, in particular to a tobacco sizing device for a mixing cabinet. Background Art

[0002] The workshop's mixing cabinets are currently fed with distribution-type material distribution vehicles. During the feeding process, the material distribution is uneven. The tobacco is thick in some places and thin in some places, and there is a large gap in the middle of the mixing cabinet. This results in uneven discharge of tobacco from the mixing cabinet and uneven distribution when it falls on the conveyor belt. During the conveyor belt conveyor process, the uneven thickness of the tobacco may cause the belt to run off track and cut obliquely, which may cause the tobacco to leak and fall to the ground, causing waste and increasing the extra work of cleaning. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a tobacco mixing cabinet tobacco mixing device, which is used to solve the problem that the thickness of the current tobacco is uneven when it falls on the belt, causing the belt to run off-center during the process of conveying the tobacco by the belt conveyor, thereby possibly causing the tobacco to leak and fall to the ground, causing waste and increasing the extra work of cleaning.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A tobacco shaving device for a mixing cabinet is used to scrape and even tobacco on a belt that transports tobacco in the mixing cabinet, comprising a crossbeam fixedly mounted on a distribution vehicle, a height adjustment device mounted on the crossbeam, and a scraper plate mounted on the height adjustment device; the scraper plate is located above the belt.

[0006] Furthermore, the height adjustment device includes a guide device fixedly connected to the crossbeam, a screw rotatably connected to the crossbeam, a nut fixedly connected to the scraper plate, and a power device for driving the screw to rotate; the scraper plate is slidably connected to the guide device; the nut is threadedly connected to the screw.

[0007] Furthermore, the power device includes a bracket fixedly connected to the crossbeam and a motor with a reducer whose housing is fixedly connected to the bracket; the output end of the motor is connected to the lead screw.

[0008] Furthermore, the lead screw is transmission-connected to the output end of the motor via a coupling.

[0009] Furthermore, the guide device includes a guide shaft with one end fixedly connected to the crossbeam and a slider slidably connected to the guide shaft; the slider is fixedly connected to the scraper plate; and the other end of the guide shaft is open.

[0010] Furthermore, a fixing block is provided on the crossbeam; and the fixing block is fixedly connected to the guide shaft.

[0011] Furthermore, the scraper plate is L-shaped, and the horizontal sides of the L-shape are respectively fixed to the slider and the nut; the bottom of the vertical side of the scraper plate is set to be sawtooth-shaped.

[0012] Furthermore, reinforcing ribs are provided between two sides of the scraper plate.

[0013] The positive effects of the utility model are:

[0014] By installing a scraper plate at the bottom of the fabric trolley of the mixing cabinet, the scraper plate moves forward and backward with the movement of the fabric trolley, so that the tobacco in uneven positions can be scraped to a uniform height in time, so that the tobacco can be evenly discharged from the cabinet; avoiding the deviation of the belt due to uneven tobacco;

[0015] At the same time, the scraper plate can also be adjusted up and down in height through the lead screw and nut, and adjusted up and down with the height of the tobacco in the cabinet, ensuring that the height of the tobacco in the cabinet is basically in a uniform plane, so that the thickness of the tobacco on the belt is consistent.

[0023] Example 1

[0024] like Figure 1 to Figure 2 As shown,

[0025] A tobacco shaving device for a mixing cabinet is used for scraping and shaving tobacco on a belt 2 that transports tobacco in a mixing cabinet 1. The device comprises a crossbeam 4 fixedly mounted on a distribution vehicle 3, a height adjustment device mounted on the crossbeam 4, and a scraper plate 5 mounted on the height adjustment device; the scraper plate 5 is located above the belt 2.

[0026] The height adjustment device includes a guide device fixedly connected to the crossbeam 4, a screw 45 rotatably connected to the crossbeam 4, a nut 44 fixedly connected to the scraper plate 5, and a power device for driving the screw 45 to rotate; the scraper plate 5 is slidably connected to the guide device; the nut 44 is threadedly connected to the screw 45.

[0027] The detailed structure is that the nut 44 is spot welded to the top of the scraper plate 5; a seat bearing 46 is fixed on the crossbeam 4, and the screw 45 is rotatably connected to the seat bearing 46; when the screw 45 rotates, the nut 44 will move up and down along the screw 45.

[0028] The power device includes a bracket 47 fixedly connected to the crossbeam 4 and a motor 48 with a reducer whose housing is fixedly connected to the bracket 47 ; the output end of the motor 48 is connected to the lead screw 45 .

[0029] The lead screw 45 is drivingly connected to the output end of the motor 48 via a coupling 49 .

[0030] The guide device includes a guide shaft 42 with one end fixedly connected to the crossbeam 4 and a slider 41 slidably connected to the guide shaft 42; the slider 41 is fixedly connected to the scraper plate 5; and the other end of the guide shaft 42 is open.

[0031] There are two guide shafts 42, which are respectively arranged on both sides of the lead screw 45. When the scraper plate 5 is adjusted up and down, it is easy to keep balance.

[0032] The cross beam 4 is provided with a fixing block 43 ; the fixing block 43 is fixedly connected to the guide shaft 42 .

[0033] The working process of the utility model is as follows:

[0034] The material distributing vehicle 3 moves back and forth linearly above the mixing cabinet 1 to distribute tobacco shreds onto the belt 2 in the mixing cabinet 1;

[0035] The scraper plate 5 moves with the distributing vehicle 3 , so that the tobacco shreds scattered by the distributing vehicle 3 onto the belt 2 can be scraped flat, thereby preventing the tobacco shreds on the belt 2 from being uneven.

[0036] When the thickness of the tobacco on the belt 2 needs to be adjusted due to different types of tobacco, the motor 48 (the motor is provided with forward and reverse functions) drives the lead screw 45 to rotate, thereby adjusting the upper and lower positions of the nut 44, and the nut 44 drives the scraper plate 5 to move up and down.

[0037] Example 2

[0038] like Figure 3 and Figure 4 As shown, the difference between this embodiment and embodiment 1 is that:

[0039] The scraper plate 5 is L-shaped, and the horizontal sides of the L-shape are respectively fixed to the slider 41 and the nut 44; the bottom of the vertical side of the scraper plate 5 is set to a sawtooth shape 52. The bottom side of the sawtooth shape 52 is in contact with the tobacco, which reduces some resistance during scraping and makes it easier to scrape the tobacco flat.

[0040] A reinforcing rib 51 is provided between the two sides of the scraper plate 5. By providing the reinforcing rib 51, the strength of the scraper plate 5 can be increased to avoid deformation during use.

[0041] Example 3

[0042] The structure of this embodiment is basically the same as that of embodiment 1.

[0043] The only difference is that automatic measurement and automatic control structures are added.

[0044] The crossbeam 4 is provided with a distance sensor, which is used to measure the thickness of the tobacco;

[0045] A controller is also provided, and the controller is connected to the distance sensor and the motor 48 signals.

[0046] The controller sets a thickness threshold of the tobacco on the belt 2. When the distance sensor measures that the tobacco thickness is greater than the set threshold, the controller sends a signal to the motor 48, and the scraper plate 5 descends to scrape the high tobacco to a lower place, so that the thickness of the tobacco on the belt 2 is uniform.
