Technical Field

[0001] The utility model relates to the field of tobacco machinery and equipment, in particular to a material tray rotating and lifting device. Background Art

[0002] In modern tobacco logistics systems, the filter rod in and out conveying platform is usually connected to the filter rod loading and unloading tray machine through a lifting device. The lifting device is used to lift the special lifting plate for rods from the exit of the loading and unloading tray machine to the entrance of the conveying platform. Therefore, the stability of the lifting device and the efficiency of the lifting transfer will directly affect the efficiency of the filter rod logistics operation.

[0026] This embodiment provides a material tray rotating and lifting device, such as Figure 1 , Figure 2 As shown, it includes a lifting plate 20 for placing a material tray, a side plate 2 and a motor 1 installed on the side plate 2. The side plate 2 is provided with a planetary gear mechanism for connecting the lifting plate 20. The motor 1 drives the planetary gear mechanism to rotate and drives the lifting plate 20 to rotate horizontally.

[0027] Specifically, Figure 1 As shown, in this embodiment, the planetary gear mechanism includes a first transmission shaft 7 fixed to the side plate 2, a first bearing seat 5 rotatably sleeved on the outside of the first transmission shaft 7 through a bearing group, a cantilever plate 9 fixedly connected to the first bearing seat 5, and a second transmission shaft 12 rotatably arranged on the cantilever plate 9. The lifting plate 20 is horizontally arranged at one end of the second transmission shaft 12.

[0028] The first transmission shaft 7 and the second transmission shaft 12 are driven by a chain 19. A driven gear 8 is disposed at the lower end of the first bearing seat 5, and a driving gear 4 is disposed on the motor shaft 3 of the motor 1. The driving gear 4 is meshed with the driven gear 8 for transmission.

[0029] In order to determine the rotation position of the lifting plate, a proximity switch 14 for detecting the position of the planetary gear mechanism is provided on the side plate 2. A sensing element that senses and cooperates with the proximity switch 14 is provided on the cantilever plate 9. A switch bracket 15 is provided on the outside of the proximity switch 14. In order to reduce friction, a second bearing seat 11 is fixedly provided on the cantilever plate 9, and the other end of the second transmission shaft 12 is rotationally matched with the second bearing seat 11 through a bearing 13.

[0030] In this embodiment, in order to realize the horizontal rotation of the lifting plate, a driving sprocket 6 is provided on the first transmission shaft 7 , and a driven sprocket 10 is provided on the second transmission shaft 12 .

[0031] In order to improve the safety of equipment operation, a first protective cover 16 is provided on the side plate 2, and a second protective cover 17 is provided on the cantilever plate 9. In order to facilitate installation and disassembly, the lifting plate 20 is connected to one end of the second transmission shaft 12 through a hoop 21.

[0032] Example 2

[0033] This embodiment provides a tray rotating and lifting device, which is different from Embodiment 1 mainly in that, in this embodiment: in order to improve the rotation positioning accuracy, the motor is a servo motor.

[0034] Example 3

[0035] This embodiment provides a material tray rotating and lifting device, which is different from the embodiment 1 mainly in that: Figure 3 As shown, a tensioning sprocket 18 is further provided between the driven sprocket 10 and the driving sprocket 6 .

[0036] Example 4

[0037] This embodiment provides a material tray rotating and lifting device, which is different from the embodiment 1 mainly in that: Figure 4 As shown, in order to ensure that the material tray is stably placed on the lifting plate, a material tray limiting plate 22 is provided on the lifting plate 20.

[0038] Specifically, the utility model provides a material tray rotating lifting device, and the specific lifting steps are as follows:

[0039] The electric drive mechanism drives the driven gear at the inner end of the cantilever mechanism to rotate, thereby driving the entire cantilever mechanism to rotate. The plate lifting mechanism is installed on the transmission shaft at the outer end of the cantilever mechanism and rotates with the driven gear as the center of the circle while following the cantilever mechanism. The cantilever mechanism drives the two sprockets at the inner and outer ends through the chain so that the plate lifting mechanism rotates in the opposite direction with the same angular velocity of the cantilever rotation with the transmission shaft at the outer end of the cantilever mechanism as the center of the circle. This ensures that the lifting plate always remains horizontal during the cantilever rotation process, achieving the purpose of lifting and conveying the lifting plate. At the same time, the transmission ratio of the electric drive mechanism and the two gears in the cantilever mechanism can be adjusted to ensure the adaptation with the conveying speed of the upstream and downstream machines.

[0040] Specifically, when the lifting plate reaches the top of the lifting plate, the motor starts, causing the driving gear to rotate, and the driving gear drives the driven gear to rotate, thereby driving the cantilever plate, the transmission shaft, the driven sprocket, and the bearing seat to start rotating around the transmission shaft. At this time, since the driving sprocket is connected to the transmission shaft and fixed to the side plate, it rotates relative to the cantilever plate. At the same time, since the chain connects the driving sprocket to the driven sprocket, the driven sprocket and the cantilever plate rotate relative to each other, and the rotation speed is the same as the cantilever plate and in the opposite direction. The lifting plate and the hoop block are fixed on the transmission shaft, synchronized with the driven sprocket. Since the relative rotation speed is the same and in the opposite direction, the lifting plate always remains in a horizontal state.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
