Description

TECHNICAL FIELD

[0001] The utility model relates to tobacco conveying technical field, concretely relates to a spread thin tobacco conveying vibration conveyor. BACKGROUND

[0002] The vibration conveyor is mainly composed of a vibrating trough, a balance body, a rack, a swing arm assembly and a transmission assembly. The motor drives the eccentric shaft to rotate continuously through the triangular belt, drives the vibrating trough to vibrate along the inclined direction, and promotes the continuous movement of the material.

[0003] The vibration conveyor has the following application scenarios in the tobacco industry: material conveying of the tobacco production line: in the tobacco processing, such as tobacco conveying after cutting and after drying, the vibration conveyor can uniformly and continuously convey the tobacco to the next process, guarantee the smooth production process, and the conveying capacity can be adjusted according to the production requirements to meet the production requirements of different scales.

[0004] Chinese patent CN201621190199.X discloses a tobacco leaf vibrating screen material distributor, which comprises a vibrating screen 1, a moisture detector 9 and a PLC control system arranged on the vibrating screen 1, a first conveying belt 18 and a second conveying belt 19 arranged at the discharge end of the vibrating screen 1, and a material distribution device arranged between the first conveying belt 18 and the second conveying belt 19.

[0005] In the tobacco conveying line, the tobacco leaves become tobacco after passing through the tobacco cutter, and there is a situation that the tobacco contains sundries. However, since the tobacco conveying layer on the vibrating trough of the outlet vibration conveyor is about 6-8 cm thick, if the sundries are just buried in the tobacco, the sundries detection and identification device cannot detect them. Therefore, the conveying vibrating trough needs to be improved to detect the sundries in the tobacco. UTILITY MODEL CONTENT

[0006] In view of the above problems, the utility model provides a vibration conveyor for spreading thin tobacco, which can automatically shake and spread the tobacco during the vibration conveying process, so as to facilitate the sundries detection and identification device to identify the sundries.

[0007] Specifically, the utility model is implemented as follows:

[0008] A vibration conveyor for spreading thin tobacco, comprising a transmission assembly, a swing arm assembly and a vibrating trough, wherein the vibrating trough is internally provided with a bottom plate, the height of the bottom plate is higher than that of the swing arm assembly, and the vibrating trough comprises:

[0009] an inlet section;

[0010] a spreading section located downstream of the inlet section and having a width greater than that of the inlet section;

[0011] The spreading section is provided with a sundries detection and identification device.

[0012] Further, the connection between the inlet section and the thinning section is trumpet-shaped, flaring towards the thinning section.

[0013] Further, the vibrating conveyor further comprises: an outlet section, the connection between the thinning section and the outlet section is trumpet-shaped, flaring towards the outlet section, and the outlet section is connected to a downstream conveying device.

[0014] Further, the vibrating conveyor further comprises: an alarm connected to the foreign matter detection and identification device, and the alarm is used to issue an alarm when foreign matter is detected.

[0015] Further, the width of the inlet section is 600mm, the width of the thinning section is 1000-1200mm, and the length of the thinning section (33) is not less than 1500mm.

[0016] The working principle of the utility model is as follows:

[0017] After the cut tobacco enters the inlet section 32, it is vibrated and conveyed forward, and when it reaches the thinning section 33, it loses the blockage of the two side plates. During the vibration process, the cut tobacco gradually spreads to both sides. When the cut tobacco is conveyed in the thinning section 33, the cut tobacco in the middle part will also gradually spread to both sides along with the conveying process, and finally spread into a thin cut tobacco layer. The foreign matter mixed in the cut tobacco layer is exposed, so that the foreign matter detection and identification device 4 can detect the foreign matter.

[0018] Compared with the prior art, the utility model has the beneficial effects that:

[0019] (1) The vibrating conveyor provided by the utility model utilizes the principle that the cut tobacco will jump during the conveying process of the vibrating conveyor, adopts the expansion and spreading mode, gradually thins the cut tobacco, and exposes the foreign matter mixed in the cut tobacco layer, so that the foreign matter detection and identification device can detect the foreign matter.

[0020] (2) The local thinning mode effectively avoids the influence of the workshop environment temperature and humidity on the moisture of the cut tobacco caused by the whole-section thinning of the vibrating trough, and is beneficial to the accurate control of the subsequent process quality indexes.

[0021] (3) After detecting the foreign matter, the alarm can remind the worker to handle it, effectively avoiding the inflow of the foreign matter into the next process and affecting the product quality. DRAWINGS

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figures 1-3 As shown, this embodiment provides a vibratory conveyor for thinning tobacco shreds, including: a transmission assembly 1, a swing arm assembly 2, and a vibratory trough 3. The vibratory trough 3 has a built-in base plate 31, the height of which is higher than that of the swing arm assembly 2, allowing the base plate 31 to expand to both sides. The vibratory trough 3 is divided into an inlet section 32, a thinning section 33, and an outlet section 34. The overall width of the inlet section 32 is consistent with that of a conventional conveyor (600mm in this embodiment). The thinning section 33 is located between the inlet section 32 and the outlet section 34, and is used for thinning the tobacco shreds and subsequent gathering to restore them to their initial thickness. A debris detection and identification device 4 is installed after the thinning section 33. The debris detection and identification device 4 is an optical camera that takes real-time pictures of materials such as tobacco shreds, and then compares and analyzes them to identify debris with a significant color difference from the tobacco shreds. It should be noted that this application does not involve improvements to the debris identification method; all identification algorithms involved are existing algorithms.

[0031] Specifically, the entrance of the thinning section 33 is a funnel-shaped structure that widens towards the thinning section 33, and the exit is a funnel-shaped structure that narrows towards the exit section 34. The base plate 31 is changed accordingly. The width of the thinning section 33 is 1000-1200mm, and the length is 1500mm. For example... Figure 4 As shown, the 6-8cm thick tobacco layer in the inlet section 32, upon reaching the flared end, loses the obstruction of the side plates. During vibration, the tobacco gradually spreads out to both sides, forming a thin tobacco layer during the thinning section 33. This exposes impurities mixed in the tobacco layer, allowing the impurity detection and identification device 4 to detect them. Upon detecting impurities, the device 4 alerts manual handling via an alarm (not shown), effectively preventing impurities from flowing into the next process and affecting product quality. After the tobacco is thinned and inspected, it reaches the closing section. Under the closing action, the tobacco gathers towards the center, and simultaneously, under vibration, gradually becomes more uniform in thickness before finally being fed into the downstream conveying equipment.

[0032] The utility model is described above with specific examples, which is only used for helping to understand the utility model and does not limit the utility model. For the skilled in the art to which the utility model belongs, according to the idea of the utility model, a number of simple deductions, deformations or substitutions can be made.
