Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, in particular to a tobacco thread and stem cutting feeding device. Background Art

[0002] During the tobacco shred process, tobacco leaves go through processes such as dehydration, drying, and cutting to eventually form shredded tobacco. When cutting the tobacco leaves, some shorter and thinner shredded tobacco will be produced, which are called shredded tobacco. They are usually not suitable for direct use in cigarette production, but can be used as filler materials in filling tobacco products.

[0003] Due to the disordered and irregular characteristics of the wire stems themselves, when the wire stems are accumulated in the feeding device after being conveyed, they may be entangled with each other and easily form agglomerates. Some existing feeding devices cannot break up the agglomerated wire stems, which not only causes the wire stems to be not loose enough, affecting the processing of subsequent processes, but also may block the feeding device and cause feeding interruption;

[0004] At the same time, in order to improve tobacco production efficiency, tobacco factories often have to operate multiple cigarette production lines at the same time. However, most feeding devices can only feed a single production line, which will increase the investment and maintenance costs of feeding equipment. In addition, in order to maintain product consistency and control production costs, it is usually necessary to feed the wire stem shreds in a quantitative manner. Some existing feeding devices cannot feed the wire stem shreds in a quantitative manner, which will lead to unstable quality of the final product and waste of wire stem shreds. Utility Model Content

[0021] See also Figure 1-5As shown, a feeding device for tobacco silk thread stems comprises an operating box 1, an inner wall of the operating box 1 is fixedly connected with a fixing strip 2, the number of the fixing strips 2 is several and evenly distributed, the fixing strips 2 are inclined, a connecting plate 3 is fixedly connected to one side of the operating box 1, a first motor 4 is installed on one side of the top of the connecting plate 3, a supporting plate 5 is fixedly connected to the other side of the top of the connecting plate 3, the number of the supporting plates 5 is two, a breaking mechanism 6 is provided in the inner cavity of the operating box 1, the fixing strip 2, the first motor 4 and the supporting plate 5 are all used in conjunction with the breaking mechanism 6, and can break up the agglomerated thread stems so that they can remain in a scattered state after falling, which not only reduces the risk of clogging the feeding device, but also facilitates subsequent production and processing, and a material is connected to the top of the operating box 1. The material frame 14 is in the shape of a cone with a top opening larger than a bottom opening. When a large amount of wire stems are loaded, the material frame 14 can provide protection and constraints around it, thereby effectively reducing the situation where the wire stems fall or overflow. The four corners of the bottom of the operation box 1 are fixedly connected with support columns 7, and the bottom end of the support column 7 is fixedly connected with a collecting frame 8. A through groove is provided in the center of the collecting frame 8. The bottom of the collecting frame 8 is funnel-shaped all around, and a feeding pipe 11 is connected to the bottom of the collecting frame 8 all around. The inner wall of the collecting frame 8 is fixedly connected with a mounting plate 18, and a through hole is provided in the center of the mounting plate 18. The inner wall of the through hole of the mounting plate 18 is fixedly connected with a supporting frame 9. The inner cavity of the supporting frame 9 is installed with a second motor 10, and the output shaft of the second motor 10 is installed through The through hole of the plate 18 extends to the top thereof, and the output shaft of the second motor 10 is fixedly connected with a cone disk 17, and the center of the cone disk 17 corresponds to the center of the operation box 1. The wire stems falling from the bottom of the operation box 1 will fall to the surface of the cone disk 17. When the second motor 10 provides power, it can drive the cone disk 17 to rotate on the top of the mounting plate 18. The bottom of the cone disk 17 and the top of the mounting plate 18 are both provided with arc-shaped guide rails and grooves for use in conjunction, so that the cone disk 17 can remain stable when rotating on the top of the mounting plate 18. The centrifugal force of the cone disk 17 can be used to evenly disperse the wire stems on its surface to the surface of the collection frame 8, and then it will continue to slide down and be discharged from the discharge pipe 11, thereby realizing simultaneous feeding of multiple production lines, and the surface of the cone disk 17 is evenly arranged There are guide grooves 15, which can increase the contact area between the wire stem wire and the surface of the cone disk 17, thereby increasing the friction between them, and can effectively guide the wire stem wire to slide and distribute more evenly along the surface of the cone disk 17. The bottom of the operation box 1 is fixedly connected with a material cover 16 through a plurality of pillars. The material cover 16 is located above the cone disk 17. The material cover 16 can provide a barrier to effectively prevent the wire stem wire from being thrown out due to the excessive rotation speed of the cone disk 17. The inner cavity of the feeding tube 11 is provided with a quantitative mechanism 12, and the surface of the support frame 9 is installed with an electric push rod 13. The number of the electric push rod 13 corresponds to that of the quantitative mechanism 12 and they are used in conjunction with each other, so as to control the wire stem wire falling from the feeding tube 11, thereby achieving the purpose of accurate quantitative feeding.It can not only reduce the generation of waste and excessive consumption, but also can be adjusted as needed to meet different production requirements.

[0022] The dispersing mechanism 6 includes movable bars 64. There are several movable bars 64 and they are evenly distributed in the inner cavity of the operating box 1. The movable bars 64 are inclined in design. The movable bars 64 and the fixed bars 2 are staggered with each other. Both ends of the movable bars 64 penetrate to the outside of the operating box 1 and are slidably connected to its inner wall. There is a certain gap between the slide bar 61 and the fixed bar 2, which can make the loose wire stems slide down. The tops of the movable bars 64 and the fixed bars 2 are fixedly connected with several teeth 65. One end of the movable bar 64 is fixedly connected to a connecting rod 63, and one end of several movable bars 64 can be fixedly connected together through the connecting rod 63. One side of the connecting rod 63 is fixedly connected to a slide bar 61. One end of the slide bar 61 penetrates to the outside of the two support plates 5 and is slidably connected to their inner walls. A slide groove frame 62 is arranged in the middle of the slide rod 61, and a through-hole is provided on the surface of the slide groove frame 62. The output shaft of the first motor 4 is fixedly connected with a curved rod 66, one end of which extends to the inner cavity of the slide groove frame 62 and is slidably connected with its inner wall. When the first motor 4 provides power to drive the curved rod 66 to rotate, one end of the curved rod 66 can slide along the inner wall of the slide groove frame 62, and under the sliding locking connection of the support plate 5, the slide rod 61 can drive the movable bar 64 to synchronously move back and forth in the operation box 1 through the connecting rod 63. At this time, the agglomerated wire stems can be broken up by the reciprocating movement of the teeth 65 at the top of the fixed bar 2 and the movable bar 64, and can be scattered and fall from the gap between the fixed bar 2 and the movable bar 64, and will remain scattered when falling to the surface of the cone disk 17, which can effectively solve the problem of wire stem agglomeration, not only can reduce the risk of blockage, but also is conducive to subsequent production and processing.

[0023] The quantitative mechanism 12 includes a load-bearing scale 121, which is located below the inner cavity of the feeding tube 11. The load-bearing scale 121 can receive and weigh the wire stems dropped from the feeding tube 11. One side of the load-bearing scale 121 penetrates into one side of the feeding tube 11 and is slidably connected to its inner wall. The top of the load-bearing scale 121 and the outer part of the feeding tube 11 are hinged with a connecting rod 122 through a support. The connecting rod 122 is inclined in design. The top of the connecting rod 122 is hinged with a baffle 123 through a support. One end of the baffle 123 penetrates into the inner cavity of the feeding tube 11 and is slidably connected to its inner wall. The middle position of the connecting rod 122 is rotatably connected with a support shaft 124. Both sides of the support shaft 124 are fixedly connected to one side of the feeding tube 11 through a support. The output shaft of the electric push rod 13 is fixedly connected to one side of the load-bearing scale 121. The load-bearing scale 121 and the electric push rod 1 3 is electrically connected. When the wire stems on the top of the load-bearing scale 121 reach the set weight, the load-bearing scale 121 will transmit a signal to the electric push rod 13. At this time, the electric push rod 13 will shrink its own stroke to let the load-bearing scale 121 slide out of the discharge tube 11, so that the wire stems supported on its surface can be discharged from the discharge tube 11, thereby achieving the effect of quantitative feeding, avoiding excessive or insufficient feeding, so that the production of cigarettes can be kept consistent and stable, and the setting of the load-bearing scale 121 can be adjusted according to different production needs to adapt to more different production needs. In addition, the load-bearing scale 121 that slides out of the discharge tube 11 will allow the connecting rod 122 to rotate around the support shaft 124, so that the baffle 123 can be pushed into the inner cavity of the discharge tube 11, and the continuously falling wire stems can be temporarily supported, thereby further improving the accuracy of quantitative feeding.

[0024] It is worth noting that the load-bearing scale 121 proposed in this technical solution is a prior art, and its working principle and beneficial effects when used are not described in detail here.

[0025] Working principle: First, the wire stems are put into the operation box 1 from the top, and then the first motor 4 is started to drive the curved rod 66 to rotate, so that one end of the curved rod 66 slides in the inner wall of the slide groove frame 62, and then the sliding rod 61 can drive the movable bar 64 to move back and forth in the operation box 1 through the connecting rod 63. Through the cooperation of the fixed bar 2 and the teeth 65 on the top of the movable bar 64, the agglomerated wire stems can be broken, and the loose wire stems after breaking will fall on the surface of the cone disk 17, and then the second motor 10 is started to drive the cone disk 17 to rotate, and under the action of the centrifugal force of the cone disk 17, the wire stems that fall from the bottom of the operation box 1 can be crushed. The wire stems are evenly distributed on the surface of the collecting frame 8 and then slide into the feeding tube 11. In the next step, when the wire stems reach the set weight at the top of the load-bearing scale 121, the electric push rod 13 will shrink the stroke to allow the load-bearing scale 121 to slide out of the feeding tube 11, so that the wire stems on the surface can fall from the feeding tube 11 to achieve the effect of quantitative feeding. The moving load-bearing scale 121 can make the connecting rod 122 rotate around the supporting shaft 124, and then the baffle 123 can be pushed into the inner cavity of the feeding tube 11, which can temporarily receive the continuously falling wire stems and improve the accuracy of quantitative feeding.
