[0036] The following is a further detailed description of the specific implementations of the present invention in conjunction with the accompanying drawings. These implementations are only used to illustrate the present invention, but not to limit the present invention.

[0037] In the description of the present invention, it should be noted that the terms "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", "fourth", and "fifth" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figure 1 and Figure 2 As shown, the utility model provides a wire suction guide rail for a cigarette making machine, the wire suction guide rail comprises a guide rail base 1, along the width direction of the guide rail base 1, the bottom of the guide rail base 1 is sequentially spaced with an outer guide rail 2, a middle guide rail 3 and an inner guide rail 4, a first wire suction channel is formed between the outer guide rail 2, the middle guide rail 3 and the guide rail base 1, and a second wire suction channel is formed between the inner guide rail 4, the middle guide rail 3 and the guide rail base 1. The two side walls of the first wire suction channel (i.e., the side of the outer guide rail 2 and the middle guide rail 3 facing the first wire suction channel) and the two side walls of the second wire suction channel (i.e., the side of the inner guide rail 4 and the middle guide rail 3 facing the second wire suction channel) are both working surfaces, a total of four working surfaces. The working surface is formed by tungsten steel inlaid on an alloy material.

[0040] During operation, the suction belts are respectively arranged at the top of the first suction channel and the second suction channel. The negative pressure suction air above the suction belts can absorb and fix the tobacco entering the first suction channel and the second suction channel from below through the suction belts. The tobacco is formed into a tobacco strip with a rectangular cross-section under the joint shaping action of the guide rails on both sides and the suction belts.

[0041] To facilitate more tobacco shreds to enter the first and second suction channels, preferably, the bottom width of the first suction channel is greater than the top width of the first suction channel, and the bottom width of the second suction channel is greater than the top width of the second suction channel. Specifically, a downwardly inclined surface can be provided at the bottom of each work, so that the bottom of the cross-section of the first and second suction channels is in a trumpet shape and the top is in a rectangular shape, that is, the bottom width of the channel is greater than the top width.

[0042] like Figure 1 and Figure 2 As shown, along the width direction of the guide rail base 1, three groups of mounting holes are arranged on the guide rail base 1 at intervals, namely the first group of mounting holes, the second group of mounting holes and the third group of mounting holes. The first group of mounting holes includes a plurality of first mounting holes 11 arranged at intervals along the length direction of the guide rail base 1, and the first mounting holes 11 are connected to the top of the outer guide rail 2 through a first fastener 61. The second group of mounting holes includes a plurality of second mounting holes 12 arranged at intervals along the length direction of the guide rail base 1, and the second mounting holes 12 are waist-shaped holes, which are connected to the top of the middle guide rail 3 through two second fasteners 62. The third group of mounting holes includes a plurality of third mounting holes 13 arranged at intervals along the length direction of the guide rail base 1, and the third mounting holes 13 are connected to the top of the inner guide rail 4 through a third fastener 63. At the same time, a plurality of first through holes 21 arranged at intervals along the length direction of the outer guide rail 2 are opened on the outer guide rail 2, and the first through holes 21 and the middle guide rail 3 are connected through a fourth fastener 64 with a first adjustment block 51 sleeved thereon. The inner guide rail 4 is provided with a plurality of second through holes 41 spaced apart along the length direction of the inner guide rail 4, and the second through holes 41 are connected to the middle guide rail 3 via a fifth fastener 65 sleeved with a second adjustment block 52. Those skilled in the art can change the size of the first adjustment block 51 and the second adjustment block 52 as required, thereby changing the spacing between the outer guide rail 2 and the middle guide rail 3, and between the inner guide rail 4 and the middle guide rail 3, so as to meet the requirements of cigarette molding of different weights and sizes.

[0043] The assembly sequence of the wire suction guide rail of the utility model is as follows:

[0044] Use the second fastener 62 to connect with the second mounting hole 12 to fix the middle guide rail 3 on the guide rail base 1;

[0045] The fourth fastener 64 is passed through the outer guide rail 2, the first adjustment block 51 and the middle guide rail 3 in sequence to fix the outer guide rail 2 and the middle guide rail 3 relatively, and then the first fastener 61 is used to connect with the first mounting hole 11 to fix the outer guide rail 2 on the guide rail base 1;

[0046] The fifth fastener 65 is passed through the inner guide rail 4, the second adjustment block 52 and the middle guide rail 3 in sequence to relatively fix the inner guide rail 4 and the middle guide rail 3. Then, the third fastener 63 is used to connect with the third mounting hole 13 to fix the inner guide rail 4 on the guide rail base 1.

[0047] Compared with the multi-point positioning guide rail assembly method used in the prior art, each guide rail in the utility model is relatively fixed to the guide rail base 1 through the "two-point positioning" method, and is assembled into an integral guide rail through the above method, which can not only solve the internal stress deformation problem caused by multi-point positioning, ensure the stability of the overall structure, but also adjust the width of the first wire suction channel and the second wire suction channel as needed to meet various cigarette forming requirements.

[0048] The first fastener 61 , the second fastener 62 , the third fastener 63 , the fourth fastener 64 and the fifth fastener 65 are all screws.

[0049] The outer guide rail 2, the middle guide rail 3, and the inner guide rail 4 are all formed by hardening alloy materials, and then coated on the surfaces of the three, and the friction coefficient of the film layer is 0.15. The coating is specifically a diamond-like coating. With the above solution, the friction force from the side of the guide rail when the tobacco moves in the suction channel is small, which is conducive to forming a stable tobacco flow.

[0050] Furthermore, a plurality of support blocks for supporting the suction wire belt are provided in the first suction wire channel and the second suction wire channel. The support block is located between two adjacent adjustment blocks. Both the support block and the adjustment block can support the suction wire belt, thereby ensuring the flatness of the suction wire belt and further ensuring the uniformity of the thickness of the tobacco layer adsorbed on the lower surface of the suction wire belt.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
