Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a bottle driving mechanism. Background Art

[0002] As one of the indispensable equipment in the packaging industry, packaging machines are mainly used to group and package the products off the production line. The packaged bottles and cans are easy to transport and store, and can also play a certain protective role for bottles and cans with high requirements on appearance.

[0003] Driven by the conveyor aisle, bottles and cans will be divided into bottles and cans arranged in a certain order after passing through the grouping device. However, when the grouped bottles and cans are transported on the conveyor aisle, some bottles and cans have insufficient friction with the conveyor aisle and slide relative to each other, which makes the arrangement of the grouped bottles and cans not compact enough and the bottles and cans are easy to loosen during packaging. Therefore, a bottle-driving device is needed to sort the bottles and cans, such as a bottle-driving mechanism with Chinese patent publication number CN212448244U, which includes a bottle-driving channel and a frame, which is arranged above the bottle-driving channel; a transmission assembly, which is provided with two, both of which are installed inside the frame and relatively distributed on both sides of the bottle-driving channel, and the transmission assembly includes a driving wheel, a driven wheel and a chain; a bottle-driving assembly, both ends of which are respectively installed on two chains; a transition plate, which is arranged inside the bottle-driving channel, and the bottle-driving assembly can push the bottles and cans to move on the transition plate. When the bottle-driving mechanism is running, the two driving wheels drive the two chains to drive, and the two chains drive the bottle-driving assembly to circulate on the inside of the frame. When the bottles and cans in the bottle-driving channel are transported to the transition plate, the bottle-driving assembly will contact the bottles and cans and push the bottles and cans to move on the transition plate. During the movement, the bottles and cans will be close to each other, so that the arrangement between the bottles and cans is more compact. When the bottles and cans enter the conveying channel, the bottles and cans may be stuck with the bottle-driving rod. If the bottle-driving rod cannot be displaced, the bottles and cans may be damaged due to the squeezing of the bottle-driving rod. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a bottle-driving mechanism which can prevent the bottle-jamming phenomenon from occurring.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a bottle-driving mechanism, comprising a plurality of bottle-driving rods arranged at equal intervals and a chain driving mechanism for driving the bottle-driving rods to circulate in a conveying channel; the chain driving mechanism comprises chains, a driving sprocket group, a passive sprocket group and a servo motor arranged on both sides of the conveying belt, the chain is sleeved on the driving sprocket group and the passive sprocket group, the servo motor drives the driving sprocket group, and the two ends of the bottle-driving rod are respectively connected to the chains on both sides; an anti-bottle jamming mechanism is provided at the inlet of the conveying channel, the anti-bottle jamming mechanism comprises an upper mounting plate arranged on the outer side of the chain, a pressure block pressed on the chain and a cylinder assembly driving the pressure block to move up and down, the cylinder assembly comprises a cylinder mounted on the upper mounting plate, a rotating shaft arranged between the two upper mounting plates and a swing arm connected to the rotating shaft, the telescopic rod of the cylinder acts on the rotating shaft, and the pressure block is mounted on the swing arm. The principle of the utility model is as follows: the bottle enters the conveying channel horizontally, and the bottle-driving rod tilts from top to bottom to enter the conveying channel. A photoelectric switch is arranged at the entrance of the conveying channel to detect the bottle jamming phenomenon. When the bottle and the bottle-driving rod are squeezed and jammed, the photoelectric switch transmits a signal to the cylinder, and the cylinder drives the rotating shaft to rotate. The rotating shaft drives the pressure block to tilt upward through the swing arm, and the upper constraint of the chain is removed. The squeezed bottle-driving rod will bounce outward with the chain to prevent the bottle-driving rod from damaging the bottle. When the fault is eliminated, the cylinder drives the pressure block to reset.

[0006] As an improvement, the pressing block is a long strip of rubber block, and the lower end of the pressing block is pressed on the roller in the middle of the chain.

[0007] As an improvement, inclined support bars are provided on both sides of the inlet of the conveying channel, and the chain section at the inlet of the conveying channel is provided between the support bars and the pressing block.

[0008] As an improvement, a lower mounting plate is provided below the inlet of the conveying channel and on the outer side of the chain, and the two ends of the support bar are respectively fixed on the upper mounting plate and the lower mounting plate.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] When the bottle is squeezed and stuck by the bottle-driving rod, the cylinder drives the shaft to rotate, and the shaft drives the pressure block to tilt upward through the swing arm. The upper constraint of the chain is removed, and the squeezed bottle-driving rod will bounce outward with the chain to prevent the bottle-driving rod from damaging the bottle.
