Description

Technical Field

[0001] This utility model relates to the field of washing machine connector technology, and in particular to a rotary joint for a bucket washing machine. Background Technology

[0002] Bottled water is widely used in daily life and offices, and its barrels are reusable. Therefore, after collecting empty barrels, bottled water manufacturers must conduct strict cleaning and disinfection processes before refilling. In this process, a fully automatic bottled water barrel cleaning machine is a key piece of equipment. Referring to the patent publication number CN210503487U, entitled "A Barrel Cleaning Machine in a Bottled Water Production Line," the cleaning machine extends a cleaning pipe into the water barrel, simultaneously spraying cleaning liquid and clean water to clean the inner wall. With the development of cleaning machines, the cleaning pipe has now been improved to be rotatable, combined with high water pressure... The water tank is sprayed from all directions, resulting in better cleaning. However, in the existing technology, the water source is connected to the water inlet spindle via a rotary joint. The water inlet spindle is fitted with a drive wheel, and the top of the water inlet spindle is connected to the cleaning pipe. Since one end of the cleaning pipe needs to extend into the water tank, the cleaning pipe is much higher than the cleaning platform. Such a cleaning pipe is too long and lacks support, making it prone to swaying and instability during high-speed rotation. Currently, the only solution is to connect the cleaning pipe by setting a raised bearing seat on the cleaning platform. However, the excessively high bearing seat structure can easily obstruct the water tank. Therefore, there is an urgent need for a structure that can improve the stability of the cleaning pipe.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] As shown in the attached figure, the present invention discloses a rotary joint for a bucket washing machine, comprising a fixed housing 1 installed at the bottom of the washing platform and a central shaft 2 rotatably disposed within the fixed housing 1. The top of the fixed housing 1 is installed at the bottom of the washing platform, and the bottom of the fixed housing 1 is provided with a water inlet pipe section 10, which has an outward convex structure for connecting to a water source. A sealing ring 20 is provided on the inner side of the fixed housing 1, and the sealing ring 20 abuts against the outer side of the bottom end of the central shaft 2. A washing pipe 3 is fixedly connected to the top end of the central shaft 2.

[0019] This utility model discloses a rotary joint for a bucket washing machine. The fixed housing 1 is hidden and installed at the bottom of the washing platform. The central shaft 2 is directly connected to the washing pipe 3 and transmits water. This does not affect the entry and exit of the washing pipe 3 into and out of the bucket for washing. At the same time, the fixed housing 1 serves as a force support and is connected to the washing platform at the top. The rotational connection between the central shaft 2 and the fixed housing 1 is located below the force support, so that the radial force generated by the rotation of the central shaft 2 can be directly transmitted to the washing platform through the fixed housing 1, ensuring that the washing pipe 3 is more stable.

[0020] Specifically, the top of the fixed housing 1 has an outward protrusion of an installation ring 11, which is fixedly installed under the cleaning table. The installation ring 11 has an opening for screws to pass through and fix the cleaning table. The fixed housing 1 is an integrally formed structure.

[0021] Specifically, the sealing ring 20 is disposed on the lower inner side of the fixed housing 1. At least two sealing rings 20 are provided. When there are two sealing rings 20, the two sealing rings 20 are spaced apart. The sealing rings 20 are step seal sealing rings 20. The two sealing rings 20 are spaced apart to form two seals, and the two sealing rings 20 are spaced apart and do not affect each other.

[0022] Specifically, the fixed housing 1 and the central shaft 2 are rotatably connected by a bearing 30, which is located between the mounting ring 11 and the sealing ring 20. The central shaft 2 is rotatably mounted inside the fixed housing 1 using the bearing 30. The central shaft 2 is driven to rotate by the power unit, and water enters through the fixed water inlet pipe section 10. The water is then transmitted to the cleaning pipe 3 through the rotating central shaft 2. Moreover, the bearing 30 is located below the mounting ring 11, so that the radial force generated by the rotation of the central shaft 2 can be directly transmitted to the cleaning table through the fixed housing 1, reducing the radial force transmitted to the cleaning pipe 3. Furthermore, the water inlet pipe section 10 is located at the bottom, and the cleaning fluid and water enter from the bottom and are blocked by the sealing ring 20 to prevent them from entering the bearing 30. At least two bearings 30 are provided. When two bearings 30 are provided, they are spaced apart, and a spacer 300 is provided between the two bearings 30. Using two or more bearings 30 can effectively improve the rotational stability of the central shaft 2 and avoid single-point support. At the same time, the spacer 30 prevents the two bearings 30 from affecting each other.

[0023] Specifically, the top of the central shaft 2 protrudes from the fixed housing 1, and a transmission component 21 is provided on the outside. The transmission component 21 may be equipped with a synchronous pulley or gear, etc. The transmission component 21 is connected to a power unit, which provides power to drive the central shaft 2 to rotate.

[0024] Specifically, a tungsten carbide coating is provided on the outer side of the central shaft 2, and the tungsten carbide coating corresponds to the sealing ring 20, making the contact area between the central shaft 2 and the sealing ring 20 more wear-resistant.

[0025] Specifically, a gap 100 is provided between the bottom of the central shaft 2 and the fixed housing 1 to prevent the end face of the central shaft 2 from contacting the fixed housing 1. To prevent the fixed housing 1 from directly rubbing against the end of the central shaft 2 when the central shaft 2 rotates, the contact is changed to a side sealing ring 20, and the sealing structure is close to the bearing 30 to maintain the stability of the central shaft 2 at high speed.

[0026] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
