In the present invention, unless otherwise explicitly stated or limited, the terms "disposed," "mounted," "connected," "communicating," and the like are to be construed broadly, e.g., as being either fixedly or removably connected; may be a mechanical connection; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1-2, a vacuum track machine conveying guide device comprises protection bars arranged on two sides of a track machine, open angle protection bars 11 are arranged at two ends of each protection bar, a plurality of clamping grooves 12 are regularly formed in the area between the open angle protection bars 11, and rollers 13 are arranged in the clamping grooves 12.

The guard bar is in a square tube structure; after the tobacco sheets are loaded into the basket in actual production, the weight of the single basket can reach more than 400kg, and the using requirements can be met according to the tensile strength 600Mpa and the yield strength 355Mpa of steel, and the bearing capacity of a square tube is equal to the pressure/the cross section area is less than allowable stress. In this example, the square tube was 1800mm long, 40mm wide, 80mm high and was made of 45# steel.

For the opening angle of the opening angle guard bar 11, it is found through analysis that:

if the two ends of the guard bar are in right angles to receive the impact of the tobacco baskets, the durability of the guard bar is poor, so that the inlet end and the outlet end of the guard bar are required to be opened, and the durability of equipment is improved. Therefore, two ends of the smoke basket are designed to be of hyperbolic structures, so that the impact of the smoke frame on the protective bar is reduced, the inclined smoke basket track alignment is facilitated to be corrected by increasing the opening angle radian of the protective bar, and the phenomenon that the inclined smoke basket collides with the protective bar, the inclined degree of the smoke basket is aggravated, and the operation is blocked is avoided.

The stress is measured and calculated according to the maximum deflection angle, when the maximum deflection is ensured to be corrected smoothly, the appearance of the protective bar does not cause negative influence on the production space, other equipment and personnel safety, and the analysis result is shown in table 1:

TABLE 1

Testing angle	Correcting trajectory	Analysis of
			4°	Invalidation	Tobacco frame inclined 5 degree clamping frame
5°	Is effective	Friction through
			6°	Nullification	The open angle does not play a supporting role
7°	Invalidation	Easy collision of pedestrian

According to the analysis result, the open angle of the guard bar is determined to be 5 degrees, namely the inner angle is 185 degrees, the outer angle is 175 degrees, namely the open angle of the open-angle guard bar 11 faces the outer side of the track, and the open angle is transited with the open area of the clamping groove 12 through a cambered surface.

The notch of draw-in groove 12 is inboard towards the track machine, and cylinder 13 rolls and installs in corresponding draw-in groove 12, and cylinder 13 salient in protective bar medial surface, makes it just contact with the last conveying product of track machine.

In order to ensure that the tobacco baskets can pass smoothly and just contact the surface of the roller 13 when the conveying track runs, so that the roller 13 generates adhesive force and traction force on the tobacco baskets to play a role in guiding actively, the diameter of the roller 13 is smaller than the width of the clamping groove 12, the ratio of the radius of the clamping groove 12 to the distance between the clamping groove 12 is 1:1, and the ratio of the axis of the roller 13 to the distances between the inner side surface and the outer side surface of the protective bar is 1: 2.

In this embodiment, it is known that the width of the 45# square tube is 40mm, the width of the clamping groove 12 is 40mm, the diameter of the roller 13 is 35mm, and it is determined that 4.5mm is needed for the roller 13 to leak out of the inner side surface of the guard bar by analyzing the distance between the smoke basket and the rail guard bar, so the axis of the roller 13 is selected to be 27mm away from the outer side surface of the square tube. In order to ensure that the rollers 13 are uniformly arranged, the distance between the center positions of the rollers 13 is determined to be 60 mm.

Based on the length of the guard bar and the spacing between the centers of the rollers 13, the optimum number of rollers 13 is determined by an experimental method, and the results are shown in table 2:

TABLE 2

Number of cylinders	Smooth and steady effect
		16	Difference (D)
18	Good effect
		20	Good effect
22	It is excellent in
		24	It is excellent in

The experimental result shows that when the number of the rollers 13 is 22 or more, there is no friction between the rollers 13, and the friction force is the smallest and the most smooth, but considering the cost, the number of the rollers 13 is determined to be 22.

The roller 13 is preferably a hollow cylindrical nylon roller with the diameter of 30mm, the thickness of 5mm and the length of 50 mm.

The protective bar is symmetrically fixed on two sides of the track machine through the base and the bolts, and a double-bolt fixed conveying guide device is adopted for ensuring the stability of the structure. Specifically, referring to fig. 3-4, the base comprises a height adjusting plate 21, a supporting rod 22 and an interval adjusting bolt, a plurality of waist holes which are beneficial to adjusting the fixed height are formed in the height adjusting plate 21, the height adjusting plate 21 is fixed below two sides of the rail machine, the interval adjusting bolt is fixed on the protective bars, and the interval between the protective bars on two sides is adjusted through adjusting the fixed depth of the interval adjusting bolt. The device is fixed at the head and the tail of the rail machine through bolts by measurement, avoids the open angle positions of the front and the rear guard bars, and is fixed with the rail machine at the positions which are about 1/5 away from the two ends.

In the implementation process, after the conveying and guiding device is installed, the safety of the tobacco basket is checked mainly through the sense organ check of workers before use: checking whether the main stress components of the smoke basket have the phenomena of integral or local instability, fatigue deformation, cracks, severe corrosion and the like; the connection of the metal structure and the welding seam have no obvious deformation cracking; whether the bolt connection is loosened or damaged or not and whether enough pretightening force exists or not so as to avoid influencing the calibration effect of the basket position running track.

Debugging operation and effect verification

After installation and safety inspection, the vacuum rail machine is utilized to convey the tobacco baskets;

and continuously testing 20 batches of cigarettes, recording the failure times, and displaying the failure times to be 0 according to the result, so that the device can realize the expected effect and is put into application.

It should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
