[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0022] like Figure 1-Figure 2As shown, the embodiment of the present application provides a device for loosening agglomerated tobacco shreds, which is used for loosening agglomerated tobacco shreds during the production process of tobacco shreds. In the production process of tobacco shreds, if agglomerated tobacco shreds appear in the tobacco shreds, it will have many negative effects. For example, in the tobacco blending process, the agglomerated tobacco shreds make the blending of the tobacco shreds not uniform. In the flavoring process, due to the presence of agglomerated tobacco shreds, the flavor cannot effectively penetrate into the center of the agglomerated tobacco shreds. When the agglomerated tobacco shreds are finally circulated to the cigarette-making machine, after the cigarette is rolled, the agglomerated tobacco shreds correspond to The quality of the cigarettes is also unqualified, causing a major quality risk. At present, the treatment of clumped tobacco is mostly to set rake nails at the outlet of the storage cabinet, or to use a vibration trough 100 to transport tobacco, and loosen the clumped tobacco through the vibration effect of the vibration trough 100. These methods are not ideal for loosening the clumped tobacco. The clumped tobacco loosening device provided in the present application is intended to improve the loosening effect of clumped tobacco, avoid the negative impact caused by the presence of clumped tobacco in each process step, and ensure the quality of tobacco and cigarettes.

[0023] The device for loosening agglomerated tobacco shreds includes a vibration trough 100, which is used for vibrating and conveying tobacco shreds, and also includes a first screen surface 201. A plurality of screen holes are evenly arranged on the first screen surface 201. The screen holes on the first screen surface 201 allow loose tobacco shreds to pass through, but do not allow agglomerated tobacco shreds to pass through. The first screen surface 201 is arranged on the vibration trough 100, and the first screen surface 201 can vibrate synchronously with the vibration, thereby realizing the conveyance of tobacco shreds on the first screen surface 201, and a gap is formed between the first screen surface 201 and the bottom of the vibration trough 100 for the loose tobacco shreds to flow forward, and also includes a blocking member. Along the flow direction of the tobacco shreds, the first screen surface 201 has an upstream end and a downstream end, the blocking member is arranged at the downstream end of the first screen surface 201, and the blocking member extends upward from the top of the first screen surface 201, and the blocking member can be inclined to extend upward from the top of the first screen surface 201, or can be perpendicular to the first screen surface 201 and extend upward from the top of the first screen surface 201.

[0024] In the working state, the tobacco shreds transported from the upstream fall onto the first screen surface 201, and driven by the vibration of the vibration trough 100, the tobacco shreds are transported forward on the first screen surface 201. While vibrating, the loose tobacco shreds pass downward through the first screen surface 201 and fall to the bottom of the vibration trough 100 and continue to be transported forward. As for the clumped tobacco shreds, they continue to vibrate forward on the first screen surface 201, and are blocked by the blocking member when running to the blocking member, so that the clumped tobacco shreds can be vibrated and loosened on the first screen surface 201 for a long time. After being loosened, they also pass downward through the first screen surface 201 and fall to the bottom of the vibration trough 100, and then continue to be transported forward. In this way, under the action of the blocking member and the first screen surface 201, the loose tobacco shreds fall onto the vibration trough 100 and are transported forward normally, and the clumped tobacco shreds are continuously vibrated and loosened on the first screen surface 201, which is more effective and thorough in loosening the clumped tobacco shreds.

[0025] In this embodiment, the blocking member can be a plate structure, preferably a second screen surface 202, and a plurality of screen holes are evenly arranged on the second screen surface 202. The screen holes on the second screen surface 202 can allow loose tobacco to pass through, but not allow clumped tobacco to pass through. The second screen surface 202 can be perpendicular to the first screen surface 201. Preferably, the second screen surface 202 is arc-shaped. When observing the second screen surface 202 in a direction perpendicular to the flow direction of the tobacco, the second screen surface 202 is an arc-shaped arc with the middle part arched toward the downstream. The arc angle of the second screen surface 202 is not greater than 90 degrees. Preferably, the arc angle of the second screen surface 202 is 60 degrees. The bottom of the second screen surface 202 is tangentially connected to the downstream end of the first screen surface 201. When a large amount of clumped tobacco is retained in front of the second screen surface 202, the loose tobacco can pass through the screen holes on the second screen surface 202 and fall into the vibration trough 100 during the vibration process, thereby preventing blockage or breakage.

[0026] In this embodiment, the vibration trough 100 includes a bottom wall 101, which is a planar structure. Side walls 102 are arranged on both sides of the bottom wall 101 along the flow direction of the tobacco, forming a trough-shaped channel for the flow of tobacco. The two sides of the first screen surface 201 are respectively connected to the side walls 102 on the left and right sides, and the left and right sides of the second screen surface 202 are also respectively connected to the side walls 102 on the left and right sides. Preferably, the first screen surface 201 is a planar structure, and the first screen surface 201 and the bottom wall 101 of the vibration trough 100 are parallel to each other, so that the tobacco on the first screen surface 201 is loosened by vibration, and the space between the first screen surface 201 and the bottom wall 101 of the vibration trough 100 is more uniform, which facilitates the forward movement of the loose tobacco.

[0027] More preferably, a heightening plate 300 is provided on the side wall 102 at a position corresponding to the second screen surface 202, and the heightening plate 300 protrudes upward from the side wall 102 of the vibration trough 100 at least to the upstream area of ​​the blocking member. Due to the upward extension of the second screen surface 202, a heightening plate 300 with a higher height is provided in the corresponding area on the side wall 102 of the vibration trough 100 to prevent the agglomerated tobacco retained on the second screen surface 202 from leaking out.

[0028] More preferably, a guide port 400 is provided on the side wall 102 upstream of the blocking member and close to the blocking member, and the guide port 400 is used to discharge the accumulated agglomerated tobacco to the outside. In the present embodiment, the guide port 400 passes through the side wall 102 of the vibration trough 100, and the bottom edge height of the guide port 400 is higher than the top of the first screen surface 201. The specific height difference can be determined according to production requirements. When too much agglomerated tobacco is retained in front of the second screen surface 202, the agglomerated tobacco can be discharged to the outside through the guide port 400 to prevent the agglomerated tobacco from crossing the second screen surface 202 and entering the next process, which is beneficial to improving the quality of the tobacco. A guide trough 401 can be provided on the outer side of the side wall 102 of the vibration trough 100 at a position corresponding to the guide port 400 to transport the discharged agglomerated tobacco to a designated location for subsequent processing.

[0029] The first screen surface 201 and the second screen surface 202 may both be screen plate structures.

[0030] The working principle of the present application is as follows: the upstream tobacco shreds are transported and fall onto the first screen surface 201, and the vibration trough 100 drives the first screen surface 201 to vibrate synchronously, and the loose tobacco shreds pass downward through the first screen surface 201 and fall onto the bottom wall 101 of the vibration trough 100 to continue to be transported forward, and the clumped tobacco shreds continue to move forward with the vibration on the first screen surface 201, and the second screen surface 202 causes the clumped tobacco shreds to be retained on the first screen surface 201, and the first screen surface 201 continuously vibrates and loosens the clumped tobacco shreds, and after loosening, the clumped tobacco shreds pass downward through the first screen surface 201 and fall onto the vibration trough 100 to be transported forward, thereby effectively improving the loosening effect of the clumped tobacco shreds, making the clumped tobacco shreds more thoroughly loosened, thereby avoiding the negative impact on the processing and production of tobacco shreds due to the presence of clumped tobacco shreds.
