Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle washing machine technology, and more specifically, it relates to a low-friction water spraying turntable mechanism for a bottle washing machine. Background Technology
[0002] Bottle washing machines are professional equipment widely used in the food, beverage, and pharmaceutical industries to clean various bottles and containers. Their main function is to remove dirt, impurities, microorganisms, etc. from the inner and outer surfaces of bottles through a series of cleaning processes, ensuring that the containers meet the hygiene standards for subsequent production or use.
[0003] Currently, bottle washing machines can be classified into three types according to their cleaning methods: immersion bottle washing machines, spray bottle washing machines, and brush bottle washing machines. Among them, spray bottle washing machines use high-pressure nozzles to spray cleaning liquid onto the inner and outer surfaces of bottles, achieving all-round spray cleaning of the bottles.
[0004] However, during the operation of the bottle washing machine, the water spray disc is a key actuator that sprays the bottles. However, as the water distribution plate in the water spray disc is continuously injected with cleaning fluid, the pressure increases. Under this pressure, the central shaft floats up. During the floating process, the central shaft will generate a large frictional force on the bearing and its internal components. Under the action of a large frictional force for a long time, the bearing and its internal components will deform or even be damaged. A low-friction water spray disc mechanism for bottle washing machines is proposed to improve the existing problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-friction water spraying turntable mechanism for bottle washing machines.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A low-friction water spray turntable mechanism for a bottle washing machine includes a central shaft, a water distribution plate seat on the outer side of the central shaft, a first injection port and a second injection port on the water distribution plate seat, the second injection port being located inside the first injection port, a second water distribution plate below the second injection port, a first water distribution plate below the first injection port, a branching hole plate below the first water distribution plate, a bearing assembly on the inner side of the branching hole plate, a base below the branching hole plate, and a first connector and a second connector on the outer side of the branching hole plate, the first connector being located above the second connector.
[0008] The bearing assembly includes a housing ring, a steel ball disposed below the housing ring, and a shaft ring disposed below the steel ball. The housing ring, steel ball, and shaft ring are combined to form a one-way thrust ball bearing.
[0009] By adopting the above technical solution, during the operation of the bottle washing machine, the base, bearing assembly, branching plate, and water distribution plate seat rotate relative to the central shaft. The first injection port, the first water distribution plate, and the first connector are connected in sequence, and the second injection port, the second water distribution plate, and the second connector are connected in sequence.

Through the reasonable arrangement of the seat ring, steel ball, and shaft ring structure, the friction force on the unidirectional thrust ball bearing is kept stable, and the damage to the bearing is correspondingly reduced.
[0010] The present invention is further configured such that: the bearing assembly includes a bearing housing, and the bearing housing is fixedly connected to the branch hole plate by bolts.
[0011] The present invention is further configured such that: a self-lubricating bushing is provided at the middle position between the bearing seat and the central shaft, and a bearing nut is provided at the bottom of the central shaft.

[0014] The present invention is further configured such that: an O-ring is provided at the midpoint between the pad and the central shaft, and a second sealing ring is provided at the midpoint between the pad and the second sealing ring.
[0015] By adopting the above technical solution, the central shaft can be positioned by setting the bearing nut. The central shaft may be subjected to axial force during operation. By tightening the bearing nut, the central shaft can be prevented from moving excessively along the axial direction, ensuring that the central shaft runs stably within a certain axial range.
[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0035] Example 1, please refer to Figure 1-3 The present invention provides the following technical solution:
[0036] See Figure 1 and Figure 3A low-friction water spray turntable mechanism for a bottle washing machine includes a central shaft 1, a water distribution plate seat 2 on the outer side of the central shaft 1, a first liquid inlet 3 and a second liquid inlet 4 on the water distribution plate seat 2, the second liquid inlet 4 being located inside the first liquid inlet 3, a second water distribution plate 102 below the second liquid inlet 4, a first water distribution plate 101 below the first liquid inlet 3, a branching hole plate 7 below the first water distribution plate 101, a bearing assembly 6 on the inner side of the branching hole plate 7, a base 5 below the branching hole plate 7, and a first connector 8 and a second connector 9 on the outer side of the branching hole plate 7, the first connector 8 being located above the second connector 9. During the operation of the bottle washing machine, the base 5, the bearing assembly 6, and the branching hole plate 7 rotate relative to the central shaft 1 and the water distribution plate seat 2.
[0037] The first injection port 3, the first water distribution plate 101, and the first connector 8 are connected in sequence. The second injection port 4, the second water distribution plate 102, and the second connector 9 are connected in sequence. The first cleaning solution is injected through the first injection port 3, flows through the first water distribution plate 101 to the first connector 8, and is sprayed into the bottle from the first connector 8 to achieve the purpose of cleaning the bottle. The second cleaning solution is injected through the second injection port 4, flows through the second water distribution plate 102 to the second connector 9, and is sprayed into the bottle from the second connector 9 to achieve the purpose of cleaning the bottle.
[0038] See Figure 2 The bearing assembly 6 includes a housing ring 67, a steel ball 68 disposed below the housing ring 67, and a shaft ring 69 disposed below the steel ball 68. The housing ring 67, the steel ball 68, and the shaft ring 69 are combined to form a one-way thrust ball bearing.
[0039] As cleaning fluid is continuously injected into the first water distribution plate 101 and the second water distribution plate 102, the pressure on the first water distribution plate 101 and the second water distribution plate 102 continuously increases. Under the action of pressure, the central shaft 1 will float relative to the first water distribution plate 101 and the second water distribution plate 102. During the floating process, the central shaft 1 will exert a force on the bearing. The force exerted on the ordinary bearing and the one-way thrust ball bearing is different.
[0040] The force process of a conventional bearing: When the central shaft 1 tends to float upward, it will generate an upward axial force. Under this condition, the contact force distribution between the balls of the conventional bearing and the inner and outer raceways will change. When the conventional bearing is subjected to a large axial force, it will generate an additional radial force. The additional radial force may cause the bearing to undergo additional deformation, and it will increase with the increase of the axial force. Moreover, when the conventional bearing is subjected to axial force, its limiting speed will decrease, and the friction will also increase accordingly, because the rolling state of the balls is disturbed by the axial force.
[0041] The force process of a one-way thrust ball bearing: When the central shaft 1 floats up, it coincides with the direction of the axial force borne by the one-way thrust ball bearing. The steel ball 68 between the shaft ring 69 and the housing ring 67 will bear this upward axial force. The steel ball 68 rolls on the raceway of the shaft ring 69 and the housing ring 67, mainly bearing the pressure in the axial direction. It will not generate a large additional radial force like ordinary bearings. Since the motion state of the steel ball 68 is mainly determined by the axial force and is not affected by the radial force, the one-way thrust ball bearing can maintain a relatively stable friction force and a low wear rate.
[0042] Through the rational arrangement of the seat ring 67, steel ball 68, and shaft ring 69, the frictional force on the one-way thrust ball bearing is kept stable, and the damage to the bearing is reduced accordingly.
[0043] See Figure 2 The bearing assembly 6 also includes a bearing housing 61, which is fixedly connected to the branch hole plate 7 by bolts.
[0044] See Figure 2 A self-lubricating bushing 62 is provided at the midpoint between the bearing housing 61 and the central shaft 1, and a bearing nut 66 is provided at the bottom of the central shaft 1.
[0045] See Figure 2 A first sealing ring 63 is provided below the self-lubricating bushing 62, and a seat ring 67 is provided below the first sealing ring 63.
[0046] See Figure 2 A pad 65 is provided on the outside of the bearing nut 66. The pad 65 is located below the shaft ring 69. The bearing nut 66 can be used to position the central shaft 1. The central shaft 1 may be subjected to axial force during operation. By tightening the bearing nut 66, the central shaft 1 can be prevented from moving excessively along the axial direction, ensuring that the central shaft 1 runs stably within a certain axial range.
[0047] See Figure 2 An O-ring 601 is provided at the midpoint between the pad 65 and the central shaft 1, and a second sealing ring 64 is provided at the midpoint between the pad 65 and the second sealing ring 64.
[0048] Specifically, the first cleaning fluid is injected through the first injection port 3, flows through the first water distribution plate 101 to the first connector 8, and is sprayed into the bottle through the first connector 8 to achieve the purpose of cleaning the bottle; the second cleaning fluid is injected through the second injection port 4, flows through the second water distribution plate 102 to the second connector 9, and is sprayed into the bottle through the second connector 9 to achieve the purpose of cleaning the bottle.
