Description

Technical Field

[0001] The invention belongs to the technical field of tobacco packaging equipment, and in particular relates to a transmission mechanism of a tobacco strip packaging beautifying device. Background Art

[0002] At present, the main shape of tobacco packaging is long strips, that is, tobacco strips, and the outer side of the tobacco strips is a transparent packaging film, which is sealed on the outer side of the tobacco strips by hot pressing.

[0003] In the prior art, the transparent packaging film on the outside of the tobacco is processed by a strip pack beauty device. The driving units of the various components of the strip pack beauty device are relatively independent driving components, which have the following problems:

[0004] 1. The equipment debugging time is long. To ensure that each driving component works together, a lot of time is needed to debug the work of each component before the equipment is operated.

[0005] 2. Low processing quality and high noise. Although debugged, each component will be out of sync and unstable after a period of operation due to the equipment's own operation problems, which seriously affects the product processing quality. In addition, the operation of multiple drive components will generate relatively large noise.

[0006] 3. The control system is complex and the linkage is poor. Each drive unit requires a corresponding control system, which makes the control system complex; it is difficult to establish linkage between the device and the production line power system, and the adaptability to the production line is poor. Summary of the invention

[0007] In view of the problems existing in the prior art, the present invention provides a transmission mechanism of a tobacco strip bag beautifying device which solves the problems of a complex driving system and poor stability of the tobacco strip bag beautifying device.

[0008] The present invention is implemented as follows: a transmission mechanism of a tobacco strip beautifying device includes a frame, and is characterized in that it also includes a double-plate drive shaft, a double-plate flat groove cam, a lower plate drive shaft, a lower plate flat groove cam, a lever flat groove cam, a feed drive shaft, a feed lever, a side pressure drive shaft and two side pressure cylindrical cams.

[0009] The double-plate drive shaft is installed on the frame, and the axis of the double-plate drive shaft is horizontally arranged and rotates around its own axis; the double-plate plane groove cam is installed on the double-plate drive shaft, and the two end surfaces of the double-plate plane groove cam are provided with grooves; the lower plate drive shaft is installed on the frame, the axis of the lower plate drive shaft is parallel to the axis of the double-plate drive shaft, and the lower plate drive shaft rotates around its own axis, and the lower plate drive shaft is connected to the double-plate drive shaft through gear transmission; the lower plate plane groove cam is installed on the lower plate drive shaft, and the end surface of the lower plate plane groove cam is provided with a groove; the shift rod plane groove cam is installed on the lower plate drive shaft, The end surface of the planar groove cam of the lever is provided with a groove; the feed drive shaft is installed on the frame, the axis of the feed drive shaft is parallel to the axis of the double-plate drive shaft, and the feed drive shaft rotates around its own axis; the end of the feed lever is sleeved on the feed drive shaft, and the other end of the feed lever is provided with a lever roller engaged with the groove of the planar groove cam of the lever; the side pressure drive shaft is installed on the frame, the axis of the side pressure drive shaft is parallel to the axis of the double-plate drive shaft, and the side pressure drive shaft is transmission-connected with the lower plate drive shaft; the two side pressure cylindrical cams are installed on the side pressure drive shaft, and the circumferential surface of the side pressure cylindrical cam is provided with a groove.

[0010] In the above technical solution, preferably, the feed drive shaft is connected to the upper plate drive shaft through a spiral bevel gear commutator, the upper plate drive shaft is installed on the frame, the axis of the upper plate drive shaft is parallel to the axis of the lower plate drive shaft and rotates around its own axis.

[0011] In the above technical solution, preferably, the two ends of the double-plate drive shaft are connected to the cam divider through a transmission belt.

[0012] The advantages and effects of the present invention are:

[0013] 1. The equipment debugging time is short. The transmission system has a single power input shaft and other drive shafts linked with the double-plate drive shaft as the power input shaft. The other drive shafts can output all the power required by each moving part of the strip bag beauty container. The equipment only needs to be connected according to the designed transmission parameters, which greatly reduces the debugging time and workload before the equipment is put into operation.

[0014] 2. Stable operation and low noise. The independent power input method can ensure the coordination of each power output component, and the components work stably, with low failure rate and low noise.

[0015] 3. Simple control and strong adaptability. Compared with the transmission multi-drive unit, the independent power greatly simplifies the complexity of the control system, and the independent power is easier to connect with the strip bag production line. BRIEF DESCRIPTION OF THE DRAWINGS
