Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts, in particular to an improved structure of a conveyor belt of two-in-one output channels of a YB416 cigarette packaging machine. Background Art

[0002] As shown in Figure 5-6, the two-in-one cigarette pack lifting part of the ZB416 packaging machine includes a driving wheel 1, a driven wheel 2 and a curved wheel 3; the three pulleys use a synchronous toothed conveyor belt 3 output mode, and the cigarette pack conveying function is realized through the synchronous toothed conveyor belt 3 with a rectangular push block 5. The currently designed push block is rectangular.

[0003] Under the action of the rectangular push block 5, the cigarette pack 4 is transported along the smoke guide plate. After entering the arc curve, the cigarette pack thrust F can be decomposed into two forces. The force F1 drives the cigarette pack forward, while the force F2 exerts pressure on the cigarette pack toward the slideway, thereby increasing the friction resistance of the slideway to the cigarette pack. Therefore, the push block must generate a sufficiently large thrust to drive the cigarette pack forward. When the cigarette pack passes through the curve during the transportation process, the extrusion force is relatively large, which can easily squeeze and deform the cigarette pack, causing cigarette squeezing, and the push block is also prone to fall off due to the force. Utility Model Content

[0004] In view of the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide an improved structure of the two-in-one output channel conveyor belt of the YB416 cigarette packaging machine to solve the problem that the cigarette packs are subjected to large extrusion force when passing through bends during the transportation process, which easily squeezes and deforms the cigarette packs, causes cigarette squeezing, and the push blocks are also easily fallen off due to the force.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] An improved structure of a two-in-one output channel conveyor belt of a YB1 cigarette packaging machine comprises a special-shaped push block fixedly connected to the conveyor belt; the special-shaped push block is used to push cigarette packs; the special-shaped push block is elastic.

[0007] Furthermore, the special-shaped push block is Ω-shaped.

[0008] Furthermore, the special-shaped push block is made of thermoplastic polyurethane elastomer material.

[0009] Furthermore, the bottom of the special-shaped push block is heat-fused together with the conveyor belt.

[0010] Furthermore, the special-shaped push block is vertically connected to the surface of the conveyor belt.

[0011] Furthermore, the surface of the special-shaped push block is provided with a wear-resistant coating.

[0012] Furthermore, the wear-resistant coating has a thickness of 0.1-0.2 mm.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The Ω-shaped push block replaces the rectangular push block, which can give the cigarette pack a tangential thrust along the curve when the cigarette pack passes through the curve, so that the cigarette pack will not be deformed, and the pressure on the cigarette pack during normal transportation is also small, which reduces the occurrence of cigarette pack damage; and the special-shaped push block is made of elastic material. When the cigarette pack is stuck due to abnormal reasons, the "Ω"-shaped push block will be deformed and can slide through the gap between the cigarette pack and the conveyor belt, which will not cause the problem of the push block falling off;

[0015] By setting the wear-resistant coating on the surface of the special-shaped push block, the service life of the special-shaped push block can be extended, and the number of uses is extended from the original 500,000 times to 1 million times. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] First of all, it should be noted that the discussion of any embodiment of the present invention is only exemplary and is not intended to imply that the scope of the present disclosure (including the claims) is limited to these examples; there are many other variations of different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity. Therefore, other embodiments are also within the scope of protection of the corresponding claims.

[0026] It should also be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meanings, especially there are no specific meanings of "primary" or "secondary" or arrangement order, and therefore cannot be understood as limiting the scope of protection of this application.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Example 1

[0029] As shown in Figure 1-6:

[0030] An improved structure of a two-in-one output channel conveyor belt of a YB416 cigarette packaging machine includes a special-shaped push block 6 fixedly connected to a conveyor belt 3; the special-shaped push block 6 is used to push cigarette packs 4; the special-shaped push block 6 is elastic.

[0031] The special-shaped push block 6 is Ω-shaped. The center line of the Ω-shaped special-shaped push block 6 is perpendicular to the surface of the conveyor belt 3.

[0032] Since the special-shaped push block 6 is elastic, when the cigarette pack 4 is occasionally stuck in the bend, the special-shaped push block 6 will deform itself, and the special-shaped push block 6 can pass through the gap between the cigarette pack 4 and the bend, which will not cause the push block to fall off the conveyor belt 3 due to its inability to deform, and also prevent the push block from damaging the cigarette pack 4.

[0033] As shown in FIG. 4 , after the special-shaped push block 6 is used, the force direction of the cigarette package 4 is basically consistent with the tangential direction of the bend, so that the cigarette package 4 can be prevented from being squeezed onto the side wall of the bend.

[0034] Example 2

[0035] The structure of this embodiment is basically the same as that of embodiment 1.

[0036] The difference is that the special-shaped push block 6 is made of thermoplastic polyurethane elastomer material.

[0037] The bottom of the special-shaped push block 6 is thermally fused with the surface of the conveyor belt 3 .

[0038] Thermoplastic polyurethane elastomer (TPU) is a type of elastomer that can be plasticized by heating and dissolved by solvents. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance and is widely used in defense, medical, food and other industries.

[0039] The outstanding features of polyurethane thermoplastic elastomers are excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low temperature resistance, good oil resistance, chemical resistance and environmental resistance. In a humid environment, the hydrolysis stability of polyether esters is far greater than that of polyesters.

[0040] Therefore, the thermoplastic polyurethane elastomer used in this embodiment has better effect than using elastic steel plates and is not easy to damage the cigarette pack.

[0041] The working principle of this embodiment is basically the same as that of Embodiment 1, and will not be described in detail.

[0042] Example 3

[0043] The structure of this embodiment is basically the same as that of embodiment 1.

[0044] The difference is that, as shown in FIG. 7 , it is found that the special-shaped push block 6 is generally used about 22,000 times, and its service life is a bit short, resulting in a high number of maintenance times, so the surface of the special-shaped push block 6 is provided with a wear-resistant coating 61 .

[0045] Repeated tests have shown that the thickness of the wear-resistant coating 61 is 0.1-0.2 mm. When the thickness is greater than 0.2 mm, the wear-resistant coating 61 will affect the elasticity of the special-shaped push block 6. When the thickness of the wear-resistant coating 61 is less than 0.1 mm, the bonding strength between the wear-resistant coating 61 and the surface of the special-shaped push block 6 is insufficient and is easy to fall off. In addition, due to the spraying process, the thickness of some parts is very thin and has no wear-resistant effect.

[0046] After applying the wear-resistant coating 61, the special-shaped push block 6 can be used about 1 million times.

[0047] The working principle of this embodiment is basically the same as that of Embodiment 1, and will not be described in detail.

[0048] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and its improved concept of the utility model, shall be covered by the protection scope of the utility model. The preferred implementation of this patent is described in detail above, but this patent is not limited to the above implementation. Within the knowledge of ordinary technicians in this field, various changes can be made without departing from the purpose of this patent.
