Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tobacco processing, and particularly relates to a stem filament conveyor. BACKGROUND

[0002] In the tobacco processing process, stem filament, as one of the important raw materials, usually needs to go through pretreatment processes such as alcoholization and moisture removal. Due to the high water content of stem filament, it needs to be transported by transfer equipment before processing. At present, the conveyor with a single-layer transmission belt structure is generally used in the industry to complete the transmission task of stem filament. However, this single-layer transmission belt structure has many problems in actual application, which seriously affects the processing efficiency and product quality of stem filament.

[0003] Firstly, the single-layer transmission belt is closely attached to the bottom support, resulting in poor air flow between the transmission belt and the stem filament. The stem filament is prone to dampness and adhesion during the transmission process due to poor ventilation. This not only affects the physical properties of the stem filament, but also may cause uneven distribution of the stem filament in the subsequent processing process, ultimately affecting the quality of the tobacco product. Secondly, although the mesh design of the single-layer transmission belt helps to drop some stem filament debris, due to the lack of sufficient gap between the transmission belt and the support, the stem filament debris is easy to be stuck in the mesh, causing incomplete dropping. This not only increases the maintenance frequency of the equipment, but also may cause the transmission belt to be blocked, affecting the production efficiency. In addition, the single-layer transmission belt structure has many cleaning dead angles, especially in the contact area between the transmission belt and the support, which is easy to accumulate stem filament debris and dust. These residues are not only difficult to clean, but also may breed bacteria, posing a threat to the hygiene and safety of the product. Although the existing technology tries to alleviate this problem by increasing cleaning equipment or improving the transmission belt material, these methods are often costly and have limited effect.

[0016] 1. The cut stem conveyor of the present application adopts a double-layer conveying member structure, including an outer transmission belt and an inner auxiliary belt. The transmission belt is used to carry cut stems, and the auxiliary belt forms a ventilation channel with the transmission belt. This design significantly improves the ventilation conditions during the cut stem conveying process, so that airflow can flow in the ventilation channel, and the airflow can be blown to the cut stems through the first material falling hole communicating with the ventilation channel to achieve the dehumidification of the cut stems.

[0018] 3. As a preferred embodiment of the present application, the design of the second chain plate further enhances the overall strength of the equipment, while ensuring that the cuttings can smoothly fall through the ventilation channel through a larger hole diameter (2mm to 5mm).

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0039] As shown in Figures 1 to 4 A cut tobacco conveying machine, comprising a machine body 1, a driving mechanism 2, a conveying member and a support structure 8 are arranged on the machine body 1, the driving mechanism 2 can drive the conveying member to make a cyclic reciprocating motion around the support structure 8, the conveying member comprises an auxiliary belt 4 located on the inner side and a transmission belt 3 located on the outer side, the outer surface of the transmission belt 3 is a cut tobacco carrying surface 31, the transmission belt 3 and the auxiliary belt 4 are connected through a support member, the transmission belt 3 and the auxiliary belt 4 have a ventilation channel 6 therebetween, and the transmission belt 3 has a plurality of first material falling holes 32 communicating with the ventilation channel 6.

[0040] The tobacco shred conveyor of the present application adopts a double-layer conveying member structure, including an outer conveying belt 3 and an inner auxiliary belt 4. The conveying belt 3 is used to carry the tobacco shreds, and the auxiliary belt 4 forms a ventilation channel 6 with the conveying belt 3. This design significantly improves the ventilation conditions during the conveying of the tobacco shreds, so that the airflow can flow in the ventilation channel 6, and the airflow can be blown to the tobacco shreds through the first material falling hole 32 in communication with the ventilation channel 6 to achieve the dehumidification of the tobacco shreds. In actual work process, the environment humidity in the tobacco processing workshop is usually high, and the existence of the ventilation channel 6 can effectively promote the air circulation and keep the tobacco shreds dry, thereby improving the quality of the subsequent processing procedures. In addition, the first material falling hole 32 on the auxiliary belt 4 is in communication with the ventilation channel 6, which provides a falling space for the debris in the tobacco shreds to slide to the first material falling hole 32, avoiding the accumulation of debris in the first material falling hole 32, thereby ensuring the communication of the tobacco shreds on the tobacco shred carrying surface 31 with the ventilation channel 6, and avoiding the jamming of the conveying member caused by the accumulation of debris, and optimizing the structural design of the tobacco shred conveyor. Furthermore, the provision of the ventilation channel 6 provides a working space for the cleaning member for the cleaning of the tobacco shred conveyor, and the debris will not be jammed in the first material falling hole 32, reducing the number of cleaning dead angles and helping to reduce the cleaning pressure of the tobacco shred conveyor.

[0041] It should be noted that, due to the circulation rotation of the conveying member of the present application, the conveying belt 3 and the auxiliary belt 4 are both circulated and rotated together, so that the outer surface of the conveying belt 3 is partially upward and partially downward or has other orientations, and the tobacco shred carrying surface 31 referred to in the present application refers to the upward part of the conveying belt 3, and is not specifically the outer surface of a certain section of the conveying belt 3. The tobacco shred conveyor of the present application is used to transfer the tobacco shreds between two procedures, Figure 2 The arrow X indicates the rotation direction of the conveying belt, and the conveying belt 3 has a feeding end 33 and a discharging end 34. The feeding end 33 is used to carry the tobacco shreds of the previous procedure, and the tobacco shreds are sent to the next procedure through the discharging end 34 after being transferred by the conveying machine. Due to the different processing times between the procedures, the processing time of the next procedure is not the same, and the tobacco shreds may need to be temporarily stored on the tobacco shred carrying surface 31, so that the tobacco shreds accumulated together have the possibility of being dampened, and need to be fully ventilated and dehumidified.

[0042] As a preferred embodiment of the present application, as shown in Figure 3 The conveying belt 3 is configured as a first chain plate, and the first material falling hole 32 is a chain plate hole of the first chain plate. The diameter of the first material falling hole 32 is L1, and 0.5mm≤L1≤1.5mm.

[0043] The transmission belt 3 is set as the first chain plate. The first chain plate has high strength and wear resistance, and can realize uniform distribution and partial discharge of cut stem through the chain plate holes. The design of the hole diameter ranging from 0.5 mm to 1.5 mm can ensure the smooth falling of cut stem and slag, and prevent larger particles of cut stem from passing through, thereby avoiding waste. In a tobacco processing workshop, this design can effectively reduce the loss of cut stem during transmission, and reduce the risk of equipment blockage.

[0044] As a preferred embodiment of the present embodiment, as shown in Figure 4 , the auxiliary belt 4 is configured as a second chain plate, and the second chain plate is provided with a second discharge hole 41 communicating with the ventilation channel 6. The second discharge hole 41 has a hole diameter L2, and 2 mm≤L2≤5 mm.

[0045] The design of the second chain plate further enhances the overall strength of the equipment, and ensures that the cut stem and slag can smoothly fall through the ventilation channel 6 through a larger hole diameter (2 mm to 5 mm). In actual use, this design is particularly suitable for tobacco processing workshops in high humidity environments, and can effectively prevent cut stem and slag from accumulating in the ventilation channel 6, thereby maintaining long-term stable operation of the equipment.

[0046] The second discharge hole 41 on the auxiliary belt 4 can be implemented in various ways. For example, the second chain plate can be made of wear-resistant materials to improve its service life; the second discharge hole 41 can be processed by punching or laser cutting to ensure the consistency and precision of the hole diameter. In addition, multiple second discharge holes 41 can be arranged at different positions of the second chain plate to further enhance the ventilation effect and slag discharge capacity.

[0047] The first chain plate and the second chain plate are used as the transmission belt 3 and the auxiliary belt 4, which on the one hand reduces the manufacturing difficulty of the transmission belt 3 and the auxiliary belt 4, and on the other hand, the first chain plate and the second chain plate have a flexible structure, which is convenient for bending to realize the circular reciprocating motion.

[0048] As a preferred example of the present embodiment, as shown in Figure 1 , Figure 2 , the support member includes a plurality of vertically extending first support rods 5, and the first support rods 5 are respectively connected to the outer edges of the auxiliary belt 4 and the transmission belt 3. Adjacent two first support rods 5 are arranged at intervals and form a ventilation hole 7 therebetween.

[0049] By setting the first support rod 5, not only the stable connection between the conveying belt 3 and the auxiliary belt 4 is realized, but also the ventilation holes 7 are formed between adjacent support rods. This design further enhances the ventilation performance of the device, ensuring that the cut tobacco remains dry during the conveying process. In actual use, the presence of the ventilation holes 7 can effectively deal with the high humidity environment in the tobacco processing workshop, reduce the occurrence of cut tobacco sticking phenomenon, and at the same time reduce the failure rate of the device due to poor ventilation.

[0050] Preferably, the support rod further comprises a plurality of vertically extending second support rods, which are located inside the first support rod 5 and are connected to the auxiliary belt 4 and the conveying belt 3 respectively.

[0051] In this application, the design of the support rod system solves the problems of air flow and stability of the single-layer conveying belt 3 structure by introducing the second support rod. The design of the second support rod further enhances the support effect between the conveying belt 3 and the auxiliary belt 4, ensuring the stability and uniformity of the conveying belt 3 during operation. In actual use, the equipment in the tobacco processing workshop usually needs to run continuously for a long time, and the design of the second support rod can effectively disperse the stress of the conveying belt 3, reduce the deformation or wear of the equipment due to long-term operation, and thus prolong the service life of the equipment. Specifically, the number and spacing of the second support rods can be adjusted according to actual needs to adapt to different specifications and models of cut tobacco conveyors. Through reasonable design and configuration, the performance of the cut tobacco conveyor can be further optimized, and the production efficiency and product quality can be improved.

[0052] As a preferred embodiment of the present application, as shown in Figure 1 、 Figure 2 The driving mechanism 2 comprises a driving member 21 to drive a driving roller 22, the number of driving rollers 22 is two and they are located at both ends of the conveying member, the auxiliary belt 4 is sleeved outside the driving roller 22, and the driving member 21 drives the driving roller 22 to rotate to drive the auxiliary belt 4 to rotate.

[0053] The driving member 21 drives the two driving rollers 22 to rotate, thereby driving the auxiliary belt 4 to rotate. This design can ensure the stable operation of the auxiliary belt 4, avoiding the problem of poor air flow caused by the close contact between the conveying belt and the bottom support in the traditional single-layer conveying belt structure. And this design can ensure the synchronous operation of the conveying belt 3 and the auxiliary belt 4, avoiding the problem of uneven distribution of cut tobacco or device jamming caused by asynchronization. In actual use, the arrangement of the driving roller 22 makes the device run more smoothly, and it is especially suitable for high-intensity continuous operation environment in the tobacco processing workshop.

[0054] The driving mechanism 2 can be designed in various ways. The driving member 21 can be an electric motor connected to the driving roller 22 through a transmission belt or a gear transmission, thereby driving the driving roller 22. In addition, the driving roller 22 can be made of a material with good wear resistance to prolong its service life. In order to further improve the transmission efficiency, anti-skid texture can be provided on the surface of the driving roller 22 to prevent the auxiliary belt 4 from slipping during rotation.

[0055] As a preferred embodiment of the present embodiment, as shown in Figure 1 、 Figure 2 The support structure 8 includes a plurality of support rollers 81 and a rotating shaft 82, the rotating shaft 82 is installed on the machine body 1, the support rollers 81 are sleeved on the rotating shaft 82 and can rotate around the rotating shaft 82, and the support rollers 81 are arranged in multiple numbers along the extension direction of the conveying member.

[0056] The present application further enhances the support effect of the transmission belt 3 by providing a plurality of support rollers 81, thereby reducing the sagging or deviation of the transmission belt 3 during operation. In actual use, this design can effectively cope with the high load demand of the cut tobacco conveying in the tobacco processing workshop, and ensure the stability and reliability of the equipment during long-time operation.

[0057] As a preferred embodiment of the present application, it further includes a ventilation unit installed on the machine body 1, the ventilation unit includes a fan and a ventilation pipe connected to the air outlet end of the fan, and the ventilation pipe has an air outlet towards the ventilation channel 6. Since the cut tobacco conveyor is usually arranged inside the workshop, the air flow in the workshop is poor, which cannot meet the needs of cut tobacco dehumidification and heat dissipation. By adding the ventilation unit, the ventilation of the cut tobacco conveyor is enhanced, and a good ventilation environment is provided for the cut tobacco. In actual use, the ventilation unit can adjust the ventilation intensity in real time according to the humidity of the workshop environment, so as to ensure that the cut tobacco always maintains the best state during the conveying process. This design is particularly suitable for tobacco processing workshops in high humidity environments, and can significantly improve the processing quality and production efficiency of cut tobacco.
