Description

Technical Field

[0001] The invention relates to the technical field of cigarette making machines, in particular to a chopper assembly. Background Art

[0002] The chopper assembly of the ZJ118 cigarette making machine controls the weight of tobacco in the cigarette by trimming excess tobacco, so the chopper assembly is in direct contact with the tobacco. The interior of the chopper assembly is gear-driven and oil-lubricated. Once the oil seal is worn or aged, the lubricating oil will leak. The leaked lubricating oil drips onto the tobacco, causing the produced cigarettes to be unqualified products - oily cigarettes.

[0003] The machine power of the ZJ118 cigarette making machine is transmitted to the power input shaft of the chopper assembly, and then transmitted to the two rotating chopper discs through the gear box. The gear box lubricating oil of the chopper assembly enters the lubricating gear box from the oil inlet pipe and flows out from the oil outlet pipe. The oil seal seals the lubricating oil inside the gear box.

[0004] When in use, the chopper disc trims and removes the excess tobacco from the tobacco bundle, and the trimmed tobacco falls into the return trough, where it is reconstituted into a tobacco bundle after screening. Due to the functional requirements of the ZJ118 cigarette making machine, the chopper assembly is designed to be able to move up and down as a whole along the guide shaft. Since the power input shaft passes through the wall panel, an opening is left on the wall panel to avoid the up and down movement of the power input shaft. The existence of this opening allows the broken tobacco and cigarette dust at the front of the wall panel to enter the back of the wall panel. In order to avoid the broken tobacco and cigarette dust remaining inside the machine and being difficult to clean, a funnel is designed under the opening at the back of the wall panel, and an opening (3-13) is designed at the top of the return trough to guide the broken tobacco and cigarette dust into the return trough.

[0005] Although the ZJ118 cigarette making machine has the splitter assembly installed in the machine wall panel, and the oil inlet, oil outlet and oil seal of the splitter assembly are installed at the rear of the wall panel to avoid direct contact with the tobacco at the front, oily smoke is still produced after oil leakage.

[0039] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as limiting the present invention.

[0040] The invention provides a chopper assembly, which is used for shearing shredded tobacco and preventing the generation of oily smoke.

[0041] In the prior art, after the oil seal of the splitter assembly fails, the lubricating oil will contaminate the broken tobacco and cigarette dust. These broken tobacco and cigarette dust with oil stains enter the return wire groove from the funnel and then enter the cigarette with the tobacco bundle again to produce oily smoke. The broken tobacco and cigarette dust adhere to the oil seal, causing the oil seal to wear out quickly and fail to leak oil. After the oil seal fails, it is difficult to replace and takes a long time, which seriously affects the effective operation rate of the equipment. It is inconvenient to check whether there is cigarette dust accumulation at the oil seal. In order to solve the above problems, the present invention proposes a splitter assembly.

[0042] Please refer to Figures 1 to 4 The present invention provides a splitter assembly, comprising: a splitter assembly 1, a wallboard 2, a waste tobacco duct 3 and an anti-oil stain smoke assembly 4. The splitter assembly 1 is used to shear tobacco bundles, the wallboard 2 is used to provide support for the splitter assembly 1 and prevent part of the tobacco dust from entering the side of the wallboard 2 away from the splitter assembly 1, and the anti-oil stain smoke assembly 4 is used to prevent the possibly contaminated tobacco dust from re-entering the waste tobacco duct 3.

[0043] The splitting knife assembly 1 is used for trimming tobacco bundles; a lubricating oil channel is provided inside the splitting knife assembly 1, and the oil inlet and the oil outlet of the lubricating oil channel are arranged on the same side. The lubricating oil channel is provided to facilitate lubrication of the internal mechanism of the splitting knife assembly 1.

[0044] The wall panel 2 is arranged on one side of the splitting knife assembly 1, and the oil inlet and the oil outlet are both facing the wall panel 2; an adjustment hole 21 is arranged on the wall panel 2, and one end of the input shaft 11 on the splitting knife assembly 1 passes through the adjustment hole 21; the adjustment hole 21 is arranged to avoid the input shaft 11 so that the splitting knife assembly 1 can move up and down. In the specific arrangement, the adjustment hole 21 is a strip hole, and the splitting knife assembly 1 can move up and down along the strip hole. Of course, in order to realize the up and down movement and locking of the splitting knife assembly 1, a corresponding sliding and locking mechanism is also required. For those skilled in the art, this is achievable, and this is not the focus of the present invention, and will not be repeated here.

[0045] The wire return pipe 3 is installed below the chopper assembly 1, and a wire return port 31 is provided at the wire return pipe 3 directly opposite the chopper assembly 1. The wire return pipe 3 is arranged below the chopper assembly 1, and a wire return port 31 is arranged directly below the chopper assembly 1. The tobacco dust generated when the chopper assembly 1 shears the tobacco bundle falls into the wire return port 31 under the action of gravity, thereby realizing the recycling of tobacco. Of course, in actual use, negative pressure can also be generated in the wire return pipe 3 by an air pump, etc., so as to facilitate the suction of the falling tobacco dust into the wire return pipe 3.

[0046] Of course, since the adjustment hole 21 is provided to realize the function of adjusting the splitting knife assembly 1 up and down, part of the smoke can still enter the side of the wallboard 2 away from the splitting knife assembly 1 through the adjustment hole 21. And the oil seal at the oil inlet, oil outlet and input shaft are all located on the side of the wallboard 2 away from the splitting knife assembly 1. Therefore, this part of the smoke passing through the adjustment hole 21 is easily contaminated by oil, especially after the oil seal is aged and fails, it is the smoke contaminated by oil that is recycled to form oily smoke. In order to prevent the generation of oily smoke, the anti-oil smoke assembly 4 is installed on the side of the wallboard 2 away from the splitting knife assembly 1, and the anti-oil smoke assembly 4 is located below the input shaft 11; the anti-oil smoke assembly 4 has a receiving groove 41, the receiving groove 41 opens upward, and the receiving groove 41 is not connected to the wire return pipe 3. In this way, the contaminated smoke can be prevented from entering the wire return pipe 3, thereby preventing the generation of oily smoke.

[0047] During specific use, the tobacco bundle is sheared by the chopping knife assembly 1, and the cut tobacco falls down and enters the wire return duct 3 for reuse. As for the tobacco dust entering the receiving groove 41 through the adjustment hole 21, since this part of the tobacco dust is easily contaminated, it is collected in the receiving groove 41 by setting up an anti-oil stain smoke assembly 4, and this part of the tobacco foam is no longer recycled, thereby effectively preventing the generation of oil stain smoke.

[0048] During specific use, the cigarette dust is concentrated in the receiving groove 41, which easily causes the broken tobacco to adhere to the oil seal of the input shaft 11, and then causes the oil seal to wear quickly and fail to leak oil. After the oil seal fails, it is difficult to replace, which takes a long time and seriously affects the effective operation rate of the equipment. To solve this problem, in a preferred implementation, it also includes a dust suction pipe 5; one end of the dust suction pipe 5 is connected to the receiving groove 41, and the other end of the dust suction pipe 5 is connected to the external negative pressure pipe 6. In this way, negative pressure can be formed in the receiving groove 41. When cigarette dust enters the upper part of the receiving groove 41 through the regulating port, it quickly enters the receiving groove 41 under the dual effects of its own gravity and negative pressure. At the same time, it can prevent the cigarette dust from adhering to the oil seal, which is beneficial to increase the life of the oil seal.

[0049] As a preferred embodiment, the anti-oil smoke assembly 4 includes a protective cover 42 and a bottom plate 43; the protective cover 42, the wall plate 2 and the bottom plate 43 together surround the receiving groove 41; the bottom plate 43 is fixedly connected to the outer top wall of the waste wire duct 3. In specific implementation, the protective cover 42 is arranged opposite to the adjustment hole 41 and in the middle and lower part of the adjustment hole 41. The protective cover 42 is provided with a dust removal hole 421, and the dust removal hole 421 is connected to the receiving groove 41. In this way, it is convenient to discharge the smoke dust through the dust removal hole 421.

[0050] As a preferred implementation, the protective cover 42 is made of a transparent material, so that the amount of smoke in the receiving groove 41 can be easily observed and cleaned in time.

[0051] As a preferred embodiment, the protective cover 42 is further provided with an escape hole 422, which is configured to escape the oil inlet pipe 7 connected to the oil inlet and the oil outlet pipe 8 connected to the oil outlet. The escape hole 422 facilitates the escape of the oil inlet pipe 7 and the oil outlet pipe 8, and helps prevent the leaked oil from flowing out along the oil inlet pipe 7 or the oil outlet pipe 8 and contaminating the work surface.

[0052] As a preferred implementation, the opening of the receiving groove 41 gradually becomes larger from bottom to top. Specifically, the receiving groove 41 is funnel-shaped, so that more cigarette dust entering through the adjustment hole 41 can be collected.

[0053] As a preferred implementation, the chopping knife assembly 1 also includes a gear box 12, a chopping knife disc 13 and a mounting plate 14; specifically, the mounting plate 14 is slidably mounted on the wall panel 2 so that the chopping knife assembly 1 can slide in the up and down directions; in specific implementation, in order to ensure that the mounting plate 14 is fixed at a certain position, a locking device is also included. For those skilled in the art, the locking device can be implemented, and locking is not the key to the present invention, which will not be repeated here. Further, the input shaft 11 passes through the mounting plate 14, and the input shaft 11 is rotationally connected to the mounting plate 14; there are two chopping knife discs 13, and both of the two chopping knife discs 13 are transmission-connected to the gear box 12, and the two chopping knife discs 13 are configured to shear tobacco bundles. In specific implementation, the center lines of the two chopping knife discs 13 are vertically arranged.

[0054] As a preferred implementation, the wire return pipe 3 is a square tube.

[0055] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
