Description

TECHNICAL FIELD

[0001] The utility model relates to tobacco production technical field, concretely relates to a kind of synchronous belt laminated pressure conveying formula sun-cured tobacco leaf muscle-removing equipment. BACKGROUND

[0002] Sun-cured tobacco (also known as "raw cut tobacco", hereinafter referred to as "tobacco") is the main raw material for producing clove cigarettes in Indonesia and other ASEAN countries, accounting for about 56% of the use amount in clove-type cigarettes, and has the effects of improving aroma quality and reducing tar; Currently, after the mature tobacco is picked, the tobacco needs to be scraped by tobacco farmers using a sugar cane knife and a peeler to remove the main veins of the tobacco, and then it is cut and dried. According to the production specification, 2 / 3 of the middle tobacco leaves and 1 / 3 of the upper and lower tobacco leaves need to be scraped, but in actual operation, due to the high labor cost of scraping (6-8 scraping workers are needed per mu), the tobacco farmers may not scrape the tobacco properly or not at all, which greatly increases the cost of picking and sorting in the later processing stage and reduces the yield and customer satisfaction.

[0003] Therefore, there is an urgent need to develop an automatic or semi-automatic scraping machine to replace manual scraping and improve the efficiency and standardization of scraping. The existing automatic equipment usually sets a muscle-removing knife above the conveyor belt to cut the main veins of the tobacco, but since the muscle-removing knife is located above the belt, it may cause resistance to the tobacco, and the pressure of the roller shaft is not enough to hold the tobacco, which may cause the tobacco to tilt and the scraping blade to damage the tobacco. Moreover, there is no guiding mechanism for the main veins of the tobacco on the belt, and the muscle-removing knife and the main veins of the tobacco are not accurately aligned, such as the "sun-cured tobacco vein scraping machine" disclosed in Chinese Utility Model Patent No. CN209403555U. SUMMARY

[0004] The utility model provides a kind of sun-cured tobacco leaf muscle-removing equipment, using synchronous belt laminated pressure conveying, muscle-removing knife is set in lower conveying belt, upper and lower laminated belt conveying can effectively hold tobacco.

[0005] The specific technical scheme of the utility model is a kind of sun-cured tobacco leaf muscle-removing equipment, including the lower conveying belt of carrying and transporting fresh tobacco leaf forward, the upper conveying belt is arranged on the lower conveying belt, and the middle of the belt of the lower conveying belt is left with a gap, which is opened along the length direction of the lower conveying belt.

[0006] Elastic supporting sheet is installed in the gap, and a special-shaped blade is also installed in the gap at the rear side of the elastic supporting sheet along the running direction of the lower conveying belt.

[0007] Further, preferably, the upper conveying belt is arranged at the tail side of the lower conveying belt through a mounting seat.

[0008] Furthermore, preferably, a driving gear is installed on the tail shaft of the lower conveyor belt, and a driven gear is correspondingly installed on the upper conveyor belt shaft, and the driving gear is meshed with the driven gear.

[0009] Furthermore, preferably, a main rib guide groove is further included, and the main rib guide groove is correspondingly installed on the front side of the elastic support piece.

[0010] Furthermore, preferably, a motor is installed on the frame of the lower conveyor belt, and the motor drives the tail shaft of the lower conveyor belt to rotate through a transmission belt.

[0011] Further, preferably, the gap is arranged along the center line of the lower conveyor belt, which separates the belt of the lower conveyor belt into a left conveyor belt and a right conveyor belt.

[0012] The beneficial effects of the utility model are as follows: the machine device is used to scrape the tobacco stems, effectively replacing manual labor, improving efficiency, and unifying quality, solving the problem of tobacco farmers' daily inadequate tobacco scraping, solving the problem of high stem content in tobacco after sun-drying, solving the problem of high processing and picking labor costs, and solving the problem of low tobacco processing yield, and ultimately realizing the beautiful vision of the processing plant no longer having to pick the tobacco stems and directly processing them after unpacking; the conveyor belt acts as a forward thrust and a platform for placing tobacco leaves; the upper conveyor belt acts to press and flatten the tobacco leaves (increasing the pressure area to effectively prevent the tobacco leaves from running off or rolling up), and with the joint cooperation of the upper and lower belts' clamping and conveying force, the main tobacco stems are scraped and removed, and the special-shaped device arranged in the middle of the lower conveyor belt accurately removes the main vein tobacco stems.

The lower conveyor belt 1 is the existing technology, which adopts a frame mechanism frame 101, and belt rollers are installed at the front and rear ends of the frame 101. The upper conveyor belt 2 is arranged on the tail side of the lower conveyor belt 1 through the mounting seat 3.

[0025] A motor 102 is installed on the frame 101 of the lower conveyor belt 1, and the motor 102 drives the tail pulley of the lower conveyor belt 1 to rotate through the transmission belt 103.

[0026] A driving gear 104 is installed on the tail shaft of the lower conveyor belt 1 , and a driven gear 201 is correspondingly installed on the shaft of the upper conveyor belt 2 , and the driving gear 104 is meshed with the driven gear 201 .

[0027] The upper and lower superimposed belt conveyors are driven by coaxial gears to achieve synchronous and unidirectional movement of the upper and lower belt contact surfaces, and the upper belt conveyor can rotate around the axis to open and close.

[0028] A gap 4 is left in the middle of the belt of the lower conveyor belt 1, and the gap 4 is set along the center line of the lower conveyor belt 1, which divides the belt of the lower conveyor belt 1 into a left conveyor belt 105 and a right conveyor belt 106. That is, a boss is set in the middle of the belt roller, so that the belt roller can be fitted with two belts, forming a gap 4 on the center line.

[0029] like Figure 1 and Figure 5 As shown, a main rib guide groove 5, an elastic support sheet 6 and a special-shaped blade 7 are sequentially installed in the gap 4 along the running direction of the lower conveyor belt 1.
