Description

Technical Field

[0001] The invention relates to the technical field of cigarette making equipment, and in particular to a cigarette waste amount sampling device for a cigarette making machine. Background Art

[0002] The PROTOS 70 cigarette making unit or ZJ17 cigarette making machine is a commonly used cigarette making equipment in the tobacco industry. Its tobacco supply system has the functions of storing, loosening, removing impurities, and controlling the flow rate of tobacco. In the process of cigarette rolling, tobacco will pass through the leveler of the cigarette making machine to trim the tobacco bundle. The leveler moves up and down according to the change of tobacco density in the tobacco rod. The tobacco bundle is trimmed by the chopper disc with grooves to make the cross section of the tobacco bundle basically uniform and the weight of the tobacco bundle on a fixed length meets the process requirements. The excess tobacco is trimmed by the leveler, and the amount of tobacco waste will be generated at this time. The tobacco trimmed by the leveler is sent to the feeding system through the waste conveying device for repeated use. The ratio of the mass of waste to the total mass of tobacco supply is called the waste amount. The difference in the control of the amount of waste will directly affect the processing quality of cigarette rolling. Insufficient waste will lead to an increase in the empty rate of cigarettes and unstable cigarette quality. Excessive waste will lead to excessive tobacco fragmentation and an increase in the dust content of cigarettes.

[0003] At present, the PROTOS 70 winding and splicing unit does not have a device for directly removing the waste wire. The waste wire conveying device usually adopts a two-stage mechanical structure: the first stage adopts a screw propeller for conveying; the second stage adopts a vibration trough for conveying.

[0004] The documents implemented by our factory require that the amount of wire return be detected after each brand change, and that the amount of wire return be detected once a week for each locomotive if the brand is not changed. When detecting the amount of wire return, because the upper part of the auxiliary wire return conveyor belt is a spiral mechanical transmission, there is a motor blocking the auxiliary wire return conveyor belt and the wire drop vibration groove, so it is impossible to take samples at the outlet of the auxiliary wire return conveyor belt, and the samples can only be taken out manually from below the wire drop vibration groove.

[0005] When sampling, it is necessary to open the rear protective cover of the locomotive and manually use tools such as cardboard to take out the waste wire under the wire drop vibration groove. The waste wire sampling time is 2 minutes. This method has the following problems: First, there are potential safety hazards and personal injury may occur; Second, it is easy to cause debris to fall; Third, it wastes manpower. The distance between the wire drop trough and the bottom is small, only about 10 cm in height. In addition, there is a lot of returned tobacco, which will accumulate above the wire drop trough, causing the locomotive to stop due to tobacco blockage. To avoid this situation, you need to use your hands to constantly move the tobacco under the wire drop trough. Therefore, one person cannot complete the sampling, and two people are needed to cooperate in timing and sampling. Fourth, different personnel have different methods, which will cause differences in data; Fifth, after sampling, it is necessary to go to a fixed area in the workshop to weigh it, which wastes time. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention develops a wire waste sampling device for a cigarette making machine, which can accurately and efficiently sample and weigh the wire waste of the cigarette making machine, thereby solving the problems of inaccurate and low efficiency in measuring the wire waste in the prior art.

[0007] The technical solution of the present invention to solve the technical problem is: The present application provides a wire waste sampling device for a cigarette making machine, comprising a bracket, an electronic scale and a conveying device, wherein the conveying device is connected to the top of the bracket, the electronic scale is arranged at the bottom of the bracket and is located below the output end of the conveying device, a universal wheel is arranged at the bottom end of the bracket, the input end of the conveying device extends outwardly and is located below the wire drop vibration groove of the cigarette making machine, and the wire waste vibrated out of the wire drop vibration groove is conveyed to the electronic scale by the conveying device.

[0008] As an improvement of the above solution, a bottom plate is provided at the bottom of the bracket, and the electronic scale is placed above the bottom plate.

[0009] As an improvement of the above solution, one side of the upper end of the bracket extends outward in a cantilever shape, and the conveying device is arranged on this side, and the input end of the conveying device is inserted below the wire drop vibration groove.

[0010] As an improvement of the above-mentioned scheme, the conveying device includes an active roller, a driven roller, a belt and a baffle, the belt is wound around the active roller and the driven roller, the baffle is symmetrically arranged above the belt, and the inner side of the baffle is inclined toward the input end of the conveying device, so that the distance between the two baffles gradually decreases from the input end to the output end of the conveying device.

[0011] As an improvement of the above solution, both ends of the active roller and the driven roller are connected to the bracket through a support plate.

[0012] As an improvement of the above solution, it also includes a control device with a timer for controlling the operating speed and time of the conveying device.

[0013] Compared with the prior art, the above solution has the following advantages or beneficial effects: The present application provides a wire waste sampling device for a cigarette making machine. Through the cooperation of a conveying device and an electronic scale, the wire waste can be accurately weighed, thereby improving the accuracy of measuring the wire waste amount. The baffle design in the conveying device allows the wire waste to gather to the middle of the belt, ensuring that all the wire waste falls into the electronic scale, avoiding the spillage of the wire waste and improving the measurement accuracy.

The electronic scale 2 is located below the output end of the conveying device 3. The input end of the conveying device 3 extends outward and is located below the wire drop vibration groove A. The wire waste is vibrated from the wire drop vibration groove A to the conveying device 3, and is transported by the conveying device 3 and slides from its output end into the electronic scale 2 to weigh the wire waste.

[0022] One side of the upper end of the bracket 1 extends outward in a cantilevered shape, and the conveying device 3 is arranged on this side, so that the input end of the conveying device 3 can be inserted below the wire drop vibration groove A.

[0023] The conveying device 3 comprises an active roller 31, a driven roller 32, a belt 33 and a baffle 34. The belt 33 is wound around the active roller 31 and the driven roller 32, and the upper surface of the belt 33 is tilted toward the side of the electronic scale 2, so that the waste yarn falls smoothly into the electronic scale 2. The baffle 34 is symmetrically arranged above the belt 33, and the inner side of the baffle 34 is tilted toward the input end of the conveying device 3, that is, the distance between the two baffles 34 gradually decreases from the input end to the output end of the conveying device 3, so that the waste yarn can gather in the middle of the belt 33, ensuring that all the waste yarn falls into the electronic scale 2, avoiding the spillage of the waste yarn and improving the measurement accuracy.

[0024] Both ends of the active roller 31 and the driven roller 32 are connected to the bracket 1 through a support plate 5 .

[0025] In the prior art, a plurality of wire dropping holes A1 are provided on the wire dropping vibration groove A. The belt 33 is located below the wire dropping holes A1 and its width is greater than the overall length of the wire dropping holes A1, so that the waste wire dropped from the wire dropping holes A1 can completely fall onto the belt 33.
