Detailed Description
The following detailed description of the embodiments of the present invention will be given in order to provide those skilled in the art with a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention.
Example 1:
as shown in fig. 1-4, the present invention provides a tobacco negative pressure dispersing apparatus, which comprises a base 1, a driving device arranged in the base 1, a supporting frame 5 arranged on the base 1, a negative pressure conveyor belt mechanism arranged inside the supporting frame 5, a negative pressure cavity 6, and a negative pressure fan 7 arranged at a suction opening of the negative pressure cavity 6. The surface of the upper part of the negative pressure cavity 6 is provided with an air inlet which is a negative pressure adsorption surface.
The supporting frame 5 has a pair of both sides vertically installed on the base 1, the negative pressure conveyor belt mechanism includes a plurality of belt pulleys 2 and a punching belt 3 wound on the belt pulleys 2, and the punching belt 3 is provided with a plurality of ventilation holes 8 to produce a negative pressure adsorption effect. The belt pulleys 2 are positioned at two sides of the contact surface of the punching belt 3 and are rotatably arranged at the inner sides of the supporting frames 5 at the corresponding sides. If there is no obstacle such as the negative pressure chamber 6 or the transmission mechanism between the pulleys 2, a conveying roller for increasing the contact surface with the punching belt 3 is installed between the pair of pulleys 2. The supporting frame 5 is a hollow frame vertically installed on the base 1 and is provided with an access window allowing a person to enter the inner side of the negative pressure conveying belt mechanism.
The belt pulley 2 which is positioned at the lower part of the belt pulley 2 and is close to the discharge end is in transmission connection with the driving device through a transmission mechanism, and is a driving belt pulley, and the belt pulleys 2 at other parts are driven belt pulleys. The negative pressure conveyor belt mechanism comprises a section of negative pressure dispersion area which is obliquely and upwards conveyed, and the punching belt 3 in the area is a belt inclined section and can be divided into a gentle conveying section and an inclined dispersion section. The inclination angle of the gentle conveying section is not more than 30 degrees, and the gentle conveying section can also extend horizontally and is mainly used for conveying tobacco leaves which are not scattered after feeding.
The belt pulley 2 is internally provided with a belt pressing wheel 4 arranged in the negative pressure dispersion area, the belt pressing wheel 4 presses on the inclined section of the belt to divide the inclined section of the belt into a gentle conveying section and an inclined dispersion section, the inclined angle of the inclined dispersion section ranges from 60 degrees to 85 degrees, and tobacco leaves are conveyed upwards from the position pressed by the belt pressing wheel 4. The negative pressure cavity 6 is arranged on the inner side of the belt inclined section of the negative pressure dispersion area, the part of the gentle conveying section, which is close to the belt pinch roller 4, and the whole section of the inclined dispersion section are close to the negative pressure adsorption surface of the negative pressure cavity 6, and the negative pressure cavity 6 influences the negative pressure adsorption effect. The shape of the negative pressure adsorption surface corresponds to that of the inclined section of the belt, the negative pressure adsorption surface is provided with two planes respectively corresponding to the gentle conveying section and the inclined dispersion section, and the cambered surface transition section between the gentle conveying section and the inclined dispersion section is matched with the cambered surface of the belt pinch roller 4.
In this embodiment, the belt pinch rollers 4 are two driven wheels respectively pressed on two sides of the punching belt 3, and a space for allowing tobacco leaves to pass through is formed between the belt pinch rollers 4. The vent holes 8 on the punching belt 3 are divided into a plurality of punching areas 9, and non-punching areas are arranged among the punching areas 9 at intervals. The length of the perforation areas 9 is more than 60cm, the width of the perforation areas is more than 20cm, and the spacing distance between the adjacent perforation areas 9 is more than 50 cm.
The perforated areas 9 are kept at certain intervals, which is more favorable for the sliding and spreading of the stacked tobacco leaves. The tobacco leaves after primary selection are conveyed on the punching belt 3, and are adsorbed on the upper belt surface of the punching belt 3 under the action of the negative pressure cavity 6 when passing through the inclined fractional section, and if some tobacco leaves are accumulated on other tobacco leaves, the tobacco leaves cannot be adsorbed because negative pressure cannot penetrate through the lower tobacco leaves, and slide downwards until the tobacco leaves are contacted with the punching area 9 without the tobacco leaves on the surface and are adsorbed by the negative pressure to be conveyed upwards. Therefore, the tobacco leaves can be automatically dispersed and spread while being conveyed by the belt through the device, and the tobacco leaves basically have only one layer, so that the device is very suitable for later visual detection.
The invention also provides a tobacco leaf dispersing method realized by using the device according to the tobacco leaf negative pressure dispersing device, which comprises the following steps:
and 3, after the tobacco leaves are scattered and spread to be thin, the tobacco leaves enter the horizontal top of the negative pressure conveyor belt mechanism to be conveyed backwards continuously after reaching the top of the negative pressure scattering area until the tobacco leaves reach the rear end discharge end for discharging.
This embodiment is because the tobacco leaf that adopts gentle transport section to accept from slope dispersion section landing is consequently needn't worry the landing tobacco leaf speed too fast, is not adsorbed by the negative pressure and drops promptly, and consequently slope dispersion section landing can set to the great structure of angle of inclination, and the tobacco leaf is more difficult to receive the retardation of bottom tobacco leaf like this, and the easy landing improves dispersion efficiency. Therefore, the tobacco leaf dispersing device has a good tobacco leaf dispersing effect, fed tobacco leaves do not need to be primarily flattened, and the dispersed tobacco leaves are basically only one layer, so that the visual detection is convenient to carry out on the back.
