Description

Technical Field

[0001] The utility model relates to the technical field of bottle packaging machinery, in particular to an independent pressure-free square bottle feeding device. Background Art

[0002] Beverage packaging machines: Before leaving the factory, products like bottled water and beverages are packed into cartons (cartoning machines) in a specific vertical and horizontal arrangement. Before packaging, they pass through a conveyor-style bottle infeed. Bottled beverages are fed one by one from the conveyor. For packaging or film wrapping, the infeed mechanism separates them into groups of 4 columns and 3 rows, 6 columns and 4 rows, 3 columns and 2 rows, or x columns and x rows, preparing for subsequent packaging or film wrapping. In the bottled packaging industry, both round and square bottles are used. When round bottles are arranged, the two cylindrical surfaces are in linear contact, leaving ample space between them for the bottle-separating claw to engage. However, when square bottles are arranged, the two cylindrical surfaces are in surface contact, leaving only the chamfered corners of the cube for the bottle-separating claw to enter. This requires that each bottle-separating line should be free of significant compression deformation and ensure that the bottles are in close contact, leaving a small gap for the bottle-separating claw to enter. The current square bottle conveyor line, once debugged and installed, can only be used for one size of square bottles. If it is used to convey square bottles of other sizes, it is bound to cause the bottles to be squeezed and deformed or the gaps left are too large, resulting in bottles falling over. Therefore, there is a need for a conveyor that can adjust the distance between two adjacent square bottle conveyor chains on the conveyor line to accommodate the conveying of square bottles of various sizes.

The screw rod is fixed to the frame by a seat bearing 914, and one end of the screw rod is also connected to a crank handle 915.

[0025] The independent single-channel pressure-free square bottle feeding device has the following advantages:

[0026] 1. Turning the crank handle to rotate the screw can make the nuts at both ends of the screw relatively close to or away from each other, thereby driving the push plate to push the sliders located at both ends of the guide rod to move, so that the scissor mechanism can be compressed or expanded. Since the connecting rods of the scissor mechanism are of the same length, the sliders can be moved on the guide rod while the spacing between the sliders can be kept the same at all times. Each slider is connected to a conveyor chain through a connecting plate, which can also drive the conveyor chains so that the spacing between the conveyor chains can be adjusted synchronously. Driven by the adjusting device, the spacing between the conveyor chains can be adjusted according to the size of the bottle to adapt to the size of the bottle.

[0027] 2. Each conveyor chain is driven by an independent drive device, and can be adjusted to prevent interference with each other after the distance between the conveyor chains.

[0028] 3. A bottle shortage detection device is installed on the frame at one end of the conveyor chain to detect the number of bottles and thus control the speed of the bottle flow.

[0029] 4. The partition plates set on the frame can adjust the spacing between the partition plates according to the spacing of the conveyor chain, and separate the bottles according to their sizes to ensure that the bottles do not fall over.

[0030] There are two width adjustment devices, one at the front and rear ends of the frame. They are connected by a synchronization chain 10. A driving gear 11, which drives the synchronization chain, is located at the end of the lead screw of one width adjustment device. A driven gear 12, driven by the synchronization chain, is located at the end of the lead screw of the other width adjustment device. Because the conveyor chain is too long, a width adjustment device is installed at the front and rear ends of the frame. The synchronization chain ensures that the spacing between the width adjustment devices is the same, ensuring that the spacing between each conveyor chain is equal before and after adjustment.

[0031] The first and second connecting rods at both ends of the scissor mechanism are short connecting rods. The connecting rods at both ends of the scissor mechanism are half the length of the internal connecting rods. The hinged joints of the first and second connecting rods at both ends of the scissor mechanism are connected to the sliders at both ends of the guide rod via second latches, providing multiple degrees of freedom to facilitate relative movement of the sliders at both ends of the scissor mechanism.

[0032] The middle of the guide rod is provided with a positioning block 916, which is hinged to the middle of the first connecting rod and the second connecting rod in the middle of the scissor mechanism through a second latch pin, so that the conveyor chains on both sides can be moved closer to the middle.

[0033] The machine also includes a hexagonal shaft bearing seat 13 and a hexagonal shaft 14 mounted in the middle of the frame and below the conveyor chain. The ends of the hexagonal shaft are connected to a drive device that drives the hexagonal shaft to rotate, and the drive device is a motor. The hexagonal shaft 14 includes a first hexagonal shaft 141 and a second hexagonal shaft 142, respectively mounted on either side of the hexagonal shaft bearing seat. The conveyor chain is provided with a hexagonal hole sprocket 15 for the hexagonal shaft to pass through and can move along the hexagonal shaft to drive the conveyor chain to rotate. The conveyor chain can slide on the hexagonal shaft without interfering with the motor's drive of the conveyor chain. The hexagonal shaft bearing seat is used to independently install the two hexagonal shafts, allowing two independent motors to independently drive the two conveyor chains, reducing installation space and saving costs.

[0034] The bottle-out detection device 4 comprises a photoelectric counting switch 401 and a mounting frame 402. The mounting frame 402 includes racks 403 mounted vertically on either side of the frame. Gear lifters 404 are mounted on the racks, moving up and down along the racks. The two gear lifters are connected to a crossbar 406 via a synchronous connecting rod 405. One of the gear lifters is equipped with a worm gear reducer. Multiple photoelectric counting switches are mounted on the crossbar. The photoelectric counting switches in the bottle-out detection device detect the number of bottles on the conveyor chain, calculate the bottle flow rate, and transmit a signal to a servo controller that controls the motor. This signal then controls the conveyor chain speed, thereby controlling the bottle flow rate and achieving a pressure-free and bottle-out-free environment. The height of the photoelectric counting switches can be adjusted via the gear lifters to accommodate bottles of different sizes.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
