Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco processing, in particular to a tobacco crushing and screening device. Background Art

[0002] Tobacco is a plant of the genus Nicotiana in the Solanaceae family. It is an annual or perennial herb that blooms and bears fruit in summer. Its leaves can be processed into a variety of products including cigars, cigarettes, snuff, cut tobacco, and flavored hookah.

[0003] In the production process of raw tobacco products, crushing is an indispensable link. The main purpose of crushing is to make the particle size of tobacco more uniform to meet the needs of subsequent processing and cigarette manufacturing. However, although the current crushing equipment can achieve a certain degree of crushing effect, there is often a problem of insufficient crushing. In order to solve this problem, it is usually necessary to use screening equipment to screen the crushed tobacco so as to select the insufficiently crushed tobacco. These insufficiently crushed tobacco will then be sent back to the crushing equipment for secondary crushing to ensure that it reaches the required particle size. However, this process is not only time-consuming and labor-intensive, but also greatly reduces the work efficiency of the entire tobacco processing. Utility Model Content

[0021] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a tobacco crushing and screening device. Figure 1-5As shown, the tobacco crushing and screening device includes: a base plate 1, two support plates 2 are fixedly installed on the top of the base plate 1, and the two support plates 2 are fixedly installed with the same box body 3; a feed pipe 4 rotatably installed on the box body 3, and a mesh cylinder 5 for screening tobacco is fixedly installed on the feed pipe 4; a rotating shaft 6 rotatably installed on the box body 3 and the mesh cylinder 5; a plurality of crushing blades 7 fixedly installed on the rotating shaft 6 for crushing tobacco; a driving motor 8 fixedly installed on the box body 3, and the output shaft of the driving motor 8 is fixedly connected to one end of the rotating shaft 6; a rotating mechanism mounted on the box body 3 for rotating the mesh cylinder 5; and a screening mechanism mounted on the two support plates 2 for screening tobacco.

[0023] In this embodiment, when in use, the tobacco to be crushed is put into the mesh cylinder 5 from the feed pipe 4, and then the drive motor 8 is started. The drive motor 8 will drive the rotating shaft 6 to rotate, and the rotating shaft 6 will drive multiple crushing blades 7 to rotate to crush the tobacco in the mesh cylinder 5. At the same time, the rotation of the rotating shaft 6 will also drive the rotation mechanism to operate, and the rotating mechanism will drive the mesh cylinder 5 to rotate, so that the tobacco can be screened at the same time during the crushing process. The tobacco that meets the crushing requirements will pass through the mesh holes of the mesh cylinder 5, and then be discharged from the box 3 and fall into the screening mechanism. It is then screened by the screening mechanism to screen out the fine residue in the crushed tobacco, thereby ensuring the processing quality of the tobacco, and those tobaccos that do not meet the crushing requirements will continue to remain in the mesh cylinder 5 until they are crushed to meet the standards. This solves the problem that the existing tobacco crushing and screening process is more time-consuming and labor-intensive and affects work efficiency.

[0024] In a further preferred embodiment of the present invention, the rotating mechanism includes: a connecting rod 9 rotatably mounted on the box body 3; two sprockets 10 respectively fixedly mounted on the connecting rod 9 and the rotating shaft 6; a chain 11 sleeved on the two sprockets 10; a gear 12 fixedly sleeved on the connecting rod 9; and a gear ring 13 fixedly sleeved on the net cylinder 5, the gear ring 13 being engaged with the gear 12.

[0025] In this embodiment, the rotating mechanism is used to rotate the mesh drum 5. During the rotation of the rotating shaft 6, the connecting rod 9 will be driven to rotate through the two sprockets 10 and the chain 11. The connecting rod 9 will drive the gear 12 to rotate, the gear 12 will drive the gear ring 13 to rotate, and the gear ring 13 will drive the mesh drum 5 to rotate. In this way, the mesh drum 5 can drive the tobacco inside to turn over, and the tobacco can be screened at the same time during the crushing process.

[0026] In a further preferred embodiment of the present invention, the screening mechanism includes: a plurality of first support blocks 14 respectively fixedly mounted on the two support plates 2, and a spring 15 is fixedly mounted on the top of the plurality of first support blocks 14; a plurality of second support blocks 16 respectively fixedly mounted on the plurality of springs 15; a screen frame 17 fixedly mounted on the plurality of second support blocks 16; and a vibration motor 18 fixedly mounted on the bottom of the screen frame 17.

[0027] In this embodiment, the screening mechanism is used to screen tobacco. After the tobacco is crushed, it will fall into the mesh frame 17, and the vibration motor 18 will be started. After the vibration motor 18 is started, with the cooperation of multiple springs 15, the mesh frame 17 can be vibrated, and then the fine residue in the tobacco can be screened out, which can ensure the processing quality of the tobacco.

[0028] In a further preferred embodiment of the present invention, a support base 19 is fixedly mounted on the top inner wall of the box body 3 , and the support base 19 is rotatably connected to the connecting rod 9 .

[0029] In this embodiment, the support seat 19 can provide a better supporting effect on the connecting rod 9 to prevent the connecting rod 9 from becoming unstable during rotation.

[0030] In a further preferred embodiment of the present invention, a non-slip pad is fixedly installed on the bottom of the base plate 1, and the non-slip pad is made of rubber.

[0031] In this embodiment, the device can be stably placed on the ground by using the rubber anti-slip pad, and is not prone to slipping.

[0032] In a further preferred embodiment of the present invention, a collection box is provided on the top of the bottom plate 1, and the collection box is used to collect tobacco debris.

[0033] In this embodiment, the sieved fine residues can be collected by a collection box, so as to facilitate centralized use of the fine residues.

[0034] In a further preferred embodiment of the present invention, a discharge port is provided at the bottom of the box body 3, and the plurality of springs 15 are all made of stainless steel.

[0035] In this embodiment, the spring 15 is made of stainless steel, which has good corrosion resistance and durability and a good service life.

[0036] To sum up, compared with the relevant technology, this solution can put the tobacco that needs to be crushed into the mesh cylinder 5 through the feed pipe 4. Through the use of the driving motor 8, the rotating shaft 6 can drive multiple crushing blades 7 to crush the tobacco in the mesh cylinder 5. During the crushing process, the rotating shaft 6 will drive the rotating mechanism to operate, causing the mesh cylinder 5 to rotate, causing the tobacco to flip in the mesh cylinder 5, so that the tobacco can be screened at the same time during the crushing process. Tobacco that meets the crushing requirements will pass through the mesh holes of the mesh cylinder 5, while those that do not meet the crushing requirements will continue to remain in the mesh cylinder 5 until they are crushed to meet the standards. This solves the problem that the existing tobacco is time-consuming, labor-intensive and affects work efficiency during the crushing and screening process. The fine residue in the crushed tobacco can be screened out through the screening mechanism, thereby ensuring the processing quality of the tobacco.

[0037] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.
