Abstract
Description
Technical Field
[0001] This utility model relates to the field of beverage equipment, specifically a centrally adjustable lifting screw device. Background Technology
[0002] The bottle feed screw assembly is an important component of packaging machinery such as filling equipment, mainly used to transport bottles to designated locations in an orderly manner. The bottle feed screw is driven by a transmission system to rotate around its own axis. The bottle is guided into the spiral groove of the bottle feed screw, and under the push of the spiral groove, the bottle moves forward along the bottle feed channel and is finally transported to the designated location. It then cooperates with subsequent transfer components to complete the filling and other packaging processes.
[0003] Traditional bottle feeding screw devices typically have fixed installations at both the driving and driven ends of the screw. When producing small-diameter bottles, it is necessary to replace them with corresponding large-diameter screws, increasing production costs. For large-diameter and special bottle types, the fixed screw position may prevent production. Utility Model Content
[0004] To address the problems of existing technologies, this invention provides a centrally adjustable lifting screw device that is compatible with different bottle types, expands the production range, adapts to the needs of small batches and multiple varieties, and reduces wear on seals by adding lubrication lines, thereby improving the service life of the equipment.
[0005] This utility model provides a center-adjustable lifting screw device, including a screw with an active end and a passive end. The active end is connected to the mounting base in sequence through an upper gear cavity and a universal joint. The transmission shaft inside the upper gear cavity drives the lower transmission shaft inside the mounting base to rotate through the universal joint. The passive end and the upper gear cavity are fixed to a side plate. The side plate is connected to a lifting and left-right adjustment mechanism, which adjusts the height of the screw and its distance from the center of the bottle.
[0006] In a further improvement, oil holes are provided at the drive shaft of the upper gear cavity and the mounting base, and the oil holes are connected by lubrication pipelines containing lubricating oil.
[0007] The beneficial effects of this utility model are as follows: 1. It can be compatible with different bottle types, expand the production range, and meet the needs of small batches and multiple varieties.
[0008] 2. For small-diameter bottles, adjusting the screw position can reduce the screw diameter, saving raw materials, simplifying processing, and reducing production costs.
[0009] 3. Bottle shape adjustment within a certain diameter range can be achieved without replacing or adjusting the screw, thus improving production efficiency.
[0010] 4. By increasing the lubrication pipeline, wear on seals can be reduced, thus extending the service life of the equipment. Attached Figure Description

[0018] This utility model provides a centrally adjustable lifting screw device, such as... Figure 1 and Figure 2 As shown, the device includes a screw with an active end 2 and a passive end 1. The active end 2 is connected to the mounting base 6 in sequence through an upper gear cavity 3 and a universal joint 5. The transmission shaft inside the upper gear cavity drives the lower transmission shaft inside the mounting base to rotate through the universal joint. The passive end and the upper gear cavity are fixed on the side plate. The side plate is connected to a lifting and left-right adjustment mechanism 7. The lifting and left-right adjustment mechanism adjusts the height of the screw and the distance from the center of the bottle.
[0019] The lifting and left-right adjustment mechanism 7 is as follows: Figure 3 and Figure 4 As shown, it includes a left-right adjustment mechanism and a lifting mechanism.
[0020] Oil holes are provided at the drive shaft of the upper gear cavity and the mounting base, and the oil holes are connected by a lubrication pipeline 4 containing lubricating oil.
