Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing, in particular to a raw tobacco collection and storage tobacco leaf loosening device. Background Art

[0002] Industrial and commercial handover is one of the important front-end links of tobacco raw materials, and it is an important checkpoint link for the back-end tobacco raw material roasting and processing. Through the application of raw tobacco storage equipment, it can effectively ensure the safety of tobacco unloading personnel, improve the efficiency of industrial and commercial handover storage, and at the same time improve the level of intelligent storage management, providing a good foundation for the subsequent stacking and warehousing of tobacco leaves.

[0003] At present, most of the tobacco leaves in China are processed by manufacturers, compressed into tobacco bricks, and then packaged and provided to cigarette factories in the form of finished cigarette packages for the next step of production. Cigarette packages need to be unpacked and sampled offline by sampling personnel in cigarette factories. Since the inside of a 40kg cigarette package may be relatively compact, samplers may sample from the outer tobacco leaves that are easier to sample. The sampling process is irregular and inaccurate, and is greatly affected by subjective human factors, and the quality of random sampling cannot be guaranteed. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1 to 5 As shown, the utility model provides a raw tobacco collection and storage tobacco leaf loosening device, comprising a first belt conveyor 100, a second belt conveyor 200 and a lifting assembly 300. Among them, a plurality of scrapers 120 are arranged on the conveying belt 110 of the first belt conveyor 100, and the plurality of scrapers 120 are evenly distributed along the length direction of the conveying belt 110; the front end of the second belt conveyor 200 is located below the rear end of the first belt conveyor 100; the lifting assembly 300 includes a bracket 310, a driving member 320 and a baffle 330, the bracket 310 is composed of two longitudinal beams 311 and a cross beam 312, the two longitudinal beams 311 are arranged on both sides of the rear end of the first belt conveyor 100, one end of the cross beam 312 is fixedly connected to the top of one longitudinal beam 311, and the other end of the cross beam 312 is fixedly connected to the top of the other longitudinal beam 311, the driving member 320 is arranged on the longitudinal beam 311, the baffle 330 is fixedly connected to the telescopic end of the driving member 320, and the driving member 320 is configured to drive the baffle 330 to move up and down.

[0033] The utility model provides a raw tobacco collection and storage tobacco leaf loosening device. The sampling personnel open the outer packaging of the tobacco leaves and place the tobacco leaves on the conveyor belt 110. Since the conveyor belt 110 will generate a certain amplitude of vibration during operation, the scraper 120 installed on the conveyor belt 110 can achieve a certain degree of loosening function for the tobacco leaves during the tobacco leaf conveying process. At the same time, the telescopic end of the driving member 320 performs cyclic telescoping to drive the baffle 330 to repeatedly move up and down. The downward movement of the baffle 330 will squeeze and separate the tobacco leaves transported to the bottom of the baffle 330 on the conveyor belt 110, thereby loosening the tobacco leaves. The loosened tobacco leaves are continued to be transported by the conveyor belt 110 and then fall into the second belt conveyor 200. The sampling personnel randomly sample the loosened tobacco leaves, which can ensure the standardization and accuracy of the random sampling process of tobacco leaves, reduce the subjective influence of human factors, and ensure the quality of random sampling.

[0034] In some embodiments, the longitudinal beam 311 is provided with a slide rail 313 in the vertical direction, and the slide rail 313 is slidably provided with a slider 314, and the slider 314 is fixedly connected to the baffle 330. By providing the slide rail 313 and the slider 314 slidably connected to the slide rail 313, the up and down movement path of the baffle 330 can be guided to prevent the baffle 330 from deflecting during the movement. The driving member 320 is provided with a mounting frame 321, and the mounting frame 321 is fixedly connected to the longitudinal beam 311, and the mounting frame 321 can support the driving member 320. Specifically, the driving member 320 can be, but is not limited to, a cylinder or a linear motor.

[0035] A lower limit positioning photoelectric detection switch and an upper limit positioning photoelectric detection switch are provided on the longitudinal beam 311. The installation position of the lower limit positioning photoelectric detection switch is higher than the horizontal plane where the top of the scraper 120 is located. The circuit control loop of the lower limit positioning photoelectric detection switch and the circuit control loop of the upper limit positioning photoelectric detection switch are both electrically connected to the driving member 320. During operation, the driving member 320 drives the baffle 330 to move downward, and the baffle 330 moves to the lower limit position to trigger the lower limit positioning photoelectric detection switch, and the lower limit positioning photoelectric detection switch controls the driving member 320 through its circuit control loop to drive the baffle 330 to move upward, and then the baffle 330 moves to the upper limit position to trigger the upper limit positioning photoelectric detection switch, and the upper limit positioning photoelectric detection switch controls the driving member 320 through its circuit control loop to drive the baffle 330 to move downward, and the above operations are repeated to realize the driving member 320 driving the baffle 330 to move back and forth up and down, and by installing the lower limit positioning photoelectric detection switch higher than the horizontal plane where the top of the scraper 120 is located, it can be avoided that the baffle 330 interferes with the scraper 120 and is damaged when moving downward.
