Description

Technical Field

[0001] The invention relates to the technical field of tobacco leaf manufacturing, and in particular to a leaf threshing, redrying and feeding process method based on a swing handle machine. Background Art

[0002] Tobacco redrying is a further deep processing of tobacco leaves after primary drying. Its purpose is to thresh and redry the tobacco leaves, remove the tobacco stems, control the moisture, physical and chemical indicators, tobacco color, insecticide and sterilization, remove sand and debris, and pack them into boxes according to different quality requirements. Tobacco leaves are classified into several different grades according to quality, and different cigarette varieties have their own different tobacco grade formulas. In production, different grades of tobacco leaves must be matched according to the formula requirements and then threshed and redryed. Swinging is a term in the tobacco industry. It refers to the process of taking tobacco leaves out of the tobacco frame according to different quality and quantity requirements and placing them on the transfer workbench during the redrying production. This process is the first step of the entire redrying production line and is crucial to the subsequent steps of the production line.

[0003] The "Tobacco Leaf Swinging Machine, Tobacco Leaf Swinging System, and Tobacco Leaf Swinging Method" with application number CN202310623913.8 can effectively solve the above problems. The invention uses a tobacco frame rotating body to automatically swing the tobacco leaves in the tobacco frame, realizing automated and orderly placement, and the tobacco leaves are completely output and will not be scattered during the swinging process. Bulk tobacco leaves need to be sorted in advance before being placed in the swinging machine, but the automatic swinging equipment in the above patent is only equipped with a set of standard leaf-laying tobacco frames. It is inefficient to manually place tobacco leaves in the standard leaf-laying tobacco frames batch by batch, and the turnover tobacco frames for transporting tobacco leaves are not compatible with the size of the standard leaf-laying tobacco frames. The turnover tobacco frames cannot enter the area where the standard leaf-laying tobacco frames are located for use, which requires manual transfer of tobacco leaves to the standard tobacco frames of the swinging machine, reducing production efficiency. If all the turnover tobacco frames are replaced with standard leaf-laying tobacco frames, the replacement cost will be too high. Summary of the invention

[0004] The purpose of the present invention is to provide a leaf threshing and re-roasting feeding process method based on a swing handle machine, so as to solve the problem that the size of the turnover tobacco frame and the standard leaf laying tobacco frame in the prior art are not compatible.

[0005] To achieve this purpose, the present invention adopts the following technical solution: The present invention provides a leaf threshing and re-roasting feeding process based on a swing handle machine, comprising the following steps:

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0025] Under the existing technology, tobacco leaves need to be placed manually in the standard cigarette frame inside the swing machine, which is inefficient. The turnover cigarette frame is the main component for transporting tobacco leaves, and its size is greatly different from the standard cigarette frame. If all the turnover cigarette frames are replaced with the standard cigarette frame size inside the swing machine, the cost will be high.

[0026] In order to solve the above problems, Figure 1 to Figure 2 As shown, the present invention provides a leaf threshing and re-roasting feeding process method based on a swing handle machine, comprising the following steps:

[0027] S1, open the circulating cigarette frame 12, and place the tobacco leaves on the first bottom plate of the circulating cigarette frame 12;

[0028] S2, conveying the turnover cigarette frame 12 to the frame changing device 1, and the frame changing device 1 inverts the standard cigarette frame 13 on the frame changing device 1;

[0029] S3, the frame changing device 1 connects the second bottom plates of the turnover cigarette frame 12 and the standard cigarette frame 13 with each other, and the tobacco leaves are clamped between the first bottom plate and the second bottom plate;

[0030] S4, the frame changing device 1 rotates the standard cigarette frame 13 and the turnover cigarette frame 12 synchronously by 180 degrees, so that the tobacco leaves are switched and placed on the second bottom plate;

[0031] S5, conveying the tobacco leaves in the standard tobacco frame 13 to the automatic tobacco stemming machine for stemming.

[0032] The turnover cigarette frame 12 of the present invention is U-shaped, and the first side panels on both sides of the turnover cigarette frame 12 can rotate around the first bottom plate. When tobacco leaves need to be placed, the first side panels are opened and the tobacco leaves are placed on the first bottom plate. The turnover cigarette frame 12 of the present invention can carry 500kg of tobacco leaves. At this time, the standard cigarette frame 13 is placed at the lower end of the bracket 11, and the bracket 11 is rotated so that the standard cigarette frame 13 on the bracket 11 is inverted on the bracket 11. The bracket 11 is symmetrical up and down. At this time, the turnover cigarette frame 12 is plugged into the bracket 11 again. The upper and lower sides of the bracket 11 are provided with telescopic devices, so that the turnover cigarette frame 12 with tobacco leaves rises and the empty standard cigarette frame 13 is lowered, so that the first bottom plate and the second bottom plate clamp the tobacco leaves. At this time, the bracket 11 is rotated to exchange the positions of the standard cigarette frame 13 and the turnover cigarette frame 12. The tobacco leaves fall into the standard cigarette frame 13 on the lower side by gravity, and the turnover cigarette frame 12 is inverted in mid-air. After that, the standard cigarette frame 13 is taken out of the bracket 11 and enters the swing machine for The handle is automatically swung, and finally the tobacco leaves enter the handle platform, and the standard cigarette frame 13 will be sent back to the bracket 11. On the other side, the bracket 11 rotates again to rotate the turnover cigarette frame 12 to the lower side. The turnover cigarette frame 12 includes a first side panel and a first bottom panel. The first side panel is rotatably installed on both sides of the first bottom panel. The turnover cigarette frame 12 can be stacked on each other. The turnover cigarette frame 12 is taken out from the bracket 11 to make room for the installation of the standard cigarette frame 13 for unloading the tobacco leaves. The first side panel is folded, which can reduce the volume of the turnover cigarette frame 12. It can also be folded by an automatic cigarette frame folding machine or manually. The automatic cigarette frame folding machine realizes the folding function by pushing the outer side of the first side panel to improve work efficiency. After stacking multiple turnover cigarette frames 12, they are transported to the bulk tobacco leaves by forklift or transportation tools, and the bulk tobacco leaves are placed on the first bottom panel again manually, so that the turnover cigarette frame 12 and the standard cigarette frame 13 can be recycled so as to carry the tobacco leaves into the bracket 11 again.

[0033] By installing the frame changing equipment 1, the upper and lower relative positions of the turnover cigarette frame 12 and the standard cigarette frame 13 can be replaced, so that the tobacco leaves can be directly switched to the standard cigarette frame 13 on the other side, thereby realizing the switching of tobacco leaves in the turnover cigarette frame 12 and the standard cigarette frame 13. There is no need to replace all the turnover cigarette frames 12, thereby reducing the modification cost. At the same time, workers can place different types of tobacco leaves in different turnover cigarette frames 12 in advance, and the standard cigarette frame 13 can provide tobacco leaves immediately when needed, thereby improving the efficiency of tobacco leaf processing.

[0034] Two rows of tobacco leaves are laid on the first bottom plate, with the head of each tobacco leaf facing outwards, and the tobacco leaves are placed horizontally in the gap between the two rows of tobacco leaves, so that each group of tobacco leaves can be evenly distributed on the first bottom plate, so that the first bottom plate and the second bottom plate can fully contact the tobacco leaves, compacting the tobacco leaves to prevent the tobacco leaves from leaking during the rotation of the bracket 11.

[0035] The frame changing device 1 includes a bracket 11 and a rotating shaft, which is rotatably installed on the side of the bracket 11. A standard cigarette frame 13 is connected to one side of the bracket 11, and a turnover cigarette frame 12 is connected to the other side of the bracket 11. The standard cigarette frame 13 and the turnover cigarette frame 12 can move along the height direction of the bracket 11, so that the first bottom plate and the second bottom plate can abut against each other and change the distance between the two.

[0036] A first sleeve is installed on one side of the bracket 11, and multiple groups of mutually parallel first limiting beams are installed on the first sleeve, a first gap is formed between the first limiting beams, and a first plug-in portion is formed at the bottom of the first base plate, and the first plug-in portion is plugged into the first gap. When the bracket 11 inverts the turnover cigarette frame 12, the turnover cigarette frame 12 can be hung on the first limiting beam through the first plug-in portion and the first gap, thereby realizing the detachable hanging of the turnover cigarette frame 12, which is convenient for workers to take and place the turnover cigarette frame 12 from the bracket 11.

[0037] A second sleeve is installed on the other side of the bracket 11, and multiple groups of parallel second limiting beams are installed on the second sleeve, a second gap is formed between the second limiting beams, and a second plug-in portion is formed at the bottom of the second base plate, and the second plug-in portion is plugged into the second gap. Through the cooperation of the second plug-in portion and the second gap, the standard cigarette frame 13 can be hung on the second limiting beam during the inversion process, thereby realizing the detachable connection of the standard cigarette frame 13, which is convenient for workers to take and place the standard cigarette frame 13 from the bracket 11.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
