[0036] According to the present invention, a stirring paddle with lifting and locking functions is provided, such as... Figures 1 to 7 As shown, the stirring paddle with lifting and locking functions is used in a stirring device, which can be, for example, a stirring pot including a pot body 10. The stirring blade 1 of the stirring paddle with lifting and locking functions is located inside the pot body 10 and can stir the materials inside the pot body 10. After stirring, if it is necessary to clean the stirring device, the stirring blade 1 can be moved to the desired position using the lifting component 4 of the stirring paddle with lifting and locking functions. Figure 1 The upper part is raised, allowing the operator to clean the bottom of the pot 10, avoiding the need to disassemble the stirring paddle in existing structures. This also avoids the difficulty of cleaning large stirring devices. Furthermore, since the stirring paddle with lifting and locking functions is located at the bottom of the pot 10, some liquid inside the pot 10 flows downwards when the stirring paddle 1 is raised. The first sealing component 6 ensures the overall sealing of the stirring paddle, preventing liquids such as water from entering the stirring paddle and damaging the structure. When the main shaft 2 is lowered, it can be locked by the locking component, ensuring the stability of subsequent operations. This stirring paddle with lifting and locking functions includes stirring paddle 1, main shaft 2, outer shaft 3, and lifting component 4.

[0037] In the following description, reference will be made to Figures 1 to 3 The detailed structure of the stirring blade 1, main shaft 2, outer shaft 3, and lifting assembly 4 of the stirring paddle with lifting and locking functions is described in detail.

[0038] like Figures 1 to 7 As shown in the embodiment, the stirring paddle with lifting and locking functions includes a stirring blade 1, a main shaft 2, an outer shaft 3, and a lifting assembly 4. Specifically, the stirring blade 1 can be located inside the stirring device, such as the pot body 10, and the stirring blade 1 can be fixedly connected to the main shaft 2 via a stirring paddle clamping nut 101. The main shaft 2 is connected to the stirring blade 1 and is used to drive the stirring blade 1 to rotate. The outer shaft 3 is sleeved on the outside of the main shaft 2. By designing the shaft of the stirring paddle in the form of an inner and outer shaft, the inner shaft (i.e., the main shaft 2) is lifted upward to achieve the function of lifting and lowering while the outer shaft remains stationary and maintains its position and support. The lifting assembly 4 lifts the main shaft 2 and resets the main shaft 2 via a reset assembly 5.

[0039] Preferably, such as Figures 1 to 7As shown, in this embodiment, the lifting assembly 4 may include a locking member and a lifting member. The locking member can be used for axial locking of the main shaft 2 and the outer shaft 3. The locking member can be disposed inside the main shaft. The lifting member can be disposed at the end of the main shaft 2 away from the stirring blade 1, and the locking member abuts against the lifting member. Specifically, the lifting member may include a lifting cylinder 401, a lifting rod 402, and a guide sleeve 403. The lifting cylinder 401 abuts against the locking member through the lifting rod 402 and the guide sleeve 403. The lifting cylinder 401 can be, for example, a device in the prior art that can lift the stirring blade with lifting and locking functions. The end face of the lifting cylinder 401 connected to the reducer 902 described below has multiple threaded holes, which can be used to fix it to the reducer 902. Preferably, the lifting rod 402 can be formed into a cuboid structure. The cuboid structure of the lifting rod 402 can prevent rotation during the lifting of the main shaft 2, making the lifting process more stable. The guide sleeve 403 can be formed as an approximately cuboid structure with a recess. The steel ball control lever 404 can be connected to the top of the cuboid structure. The recess can be formed as a cuboid and cooperate with the lifting rod 402 to achieve guidance during the lifting process.

[0040] Preferably, such as Figures 1 to 7 As shown, in this embodiment, the locking component may include a steel ball control lever 404, a first return spring 406, locking steel balls 407, and a retaining ring 408. The first end of the steel ball control lever 404 extends into the interior of the main shaft 2, and the second end of the steel ball control lever 404 abuts against the guide sleeve 403. The first return spring 406 is sleeved on the second end of the steel ball control lever 404. The retaining ring 408 is located at the end of the outer shaft 3 away from the stirring blade 1. Multiple locking steel balls 407 are located on the outer periphery of the steel ball control lever 404, with one end abutting against the steel ball control lever 404 and the other end passing through the side wall of the main shaft 2 and abutting against the retaining ring 408. Specifically, the steel ball control lever 404 is used to unlock and lock the multiple locking steel balls 407. Figure 5 and Figure 6As shown, each locking steel ball 407 may include a connecting part and two steel balls located at both ends of the connecting part. The two steel balls respectively abut against the steel ball operating lever 404 and the retaining ring 408. The retaining ring 408 may have screw holes and be fixedly connected to the outer shaft 3 through the screw holes. The first return spring 406 is sleeved on the second end of the steel ball operating lever 404, that is, the end near the lifting member. In this way, after the lifting member pushes the steel ball operating lever 404 upward, the steel ball operating lever 404 can be reset by the first return spring 406. Preferably, a retaining ring 405 is provided at the end of the first return spring 406 near the lifting member. The retaining ring 405 is sandwiched between the main shaft 2 and the steel ball operating lever 404 to fix the first return spring 406. Preferably, the steel ball control lever 404 has an unlocking part, which is disposed at the first end of the steel ball control lever 404 and correspondingly locks the steel ball 407. The unlocking part is recessed inward from the outer surface of the steel ball control lever 404, so that the diameter of the unlocking part is smaller than the diameter of the steel ball control lever 404. Thus, when the steel ball control lever 404 is lifted upward by the lifting member, the unlocking part causes the multiple locked steel balls 407 to move towards the steel ball control lever 404, thereby separating from the retaining ring 408 and realizing the axial separation of the main shaft 2 and the outer shaft 3.

[0041] Preferably, such as Figures 1 to 7 As shown, in this embodiment, the reset assembly 5 may include a second reset spring 501 and a spring cover 502. The second reset spring 501 is disposed between the outer shaft 3 and the main shaft 2. The spring cover 502 is sleeved on the main shaft 2 and abuts against the second reset spring 501. A retaining ring 408 is sleeved on the spring cover 502. A locking steel ball 407 passes through the side wall of the main shaft 2 and abuts against the spring cover 502 and the retaining ring 408. The reset assembly 5 enables the main shaft 2 to reset after being lifted. The reset can be achieved by the gravity of the main shaft 2 and the restoring force of the second reset spring 501. The second reset spring 501 is disposed between the main shaft 2 and the outer shaft 3. A spring cover 502 is disposed at the end of the second reset spring 501 near the lifting member to fix the second reset spring 501. In addition, the setting position of the spring cover 502 is also the setting position of the locking steel ball 407. Thus, the locking steel ball 407 needs to pass through the spring cover 502 first and then the retaining ring 408, which can also achieve secondary fixation.

[0042] Preferably, such as Figures 1 to 7As shown, in this embodiment, the first sealing assembly 6 may include a sealing mounting member 601. The first end of the sealing mounting member 601 extends into the stirring blade 1. A first sealing ring 603 is provided between the sealing mounting member 601 and the stirring blade 1. There may be two first sealing rings 603, and a spacer sleeve 602 may be provided between the two first sealing rings 603 for fixing and separation. The second end of the sealing mounting member 601 is sleeved on the outer periphery of the main shaft 2. A first waterproof seal 604 and a second sealing ring 605 are provided between the second end of the sealing mounting member 601 and the main shaft 2. The second sealing ring 605 is located at the end of the first waterproof seal 604 away from the stirring blade 1. The first sealing ring 603 may be, for example, an O-ring. The first waterproof seal 604 may be, for example, a waterproof seal with an umbrella-shaped structure, used to provide waterproofing and prevent liquid inside the pot 10 from flowing into the main shaft 2. The second sealing ring 605 may be, for example, a lip seal, achieving a secondary seal.

[0043] Preferably, such as Figures 1 to 7 As shown in the embodiment, the stirring paddle with lifting and locking functions can be used in a stirring device. The stirring paddle blade 1 extends into the stirring device. The stirring paddle with lifting and locking functions can also include a positioning component 7, which is disposed on the outer periphery of the outer shaft 3. The positioning component 7 can include a support base 701, a bearing 702, and an outer shaft end cap 703. The support base 701 is sleeved on the outer shaft 3, and the outer shaft 3 and the support base 701 are connected by a bearing. One end of the support base 701 is connected to the stirring device, and the outer shaft end cap 703 is disposed at the end of the outer shaft 3. The support base 701 is used to fix the pot body 10 and fix the outer shaft 3, thus fixing the entire device. The number of bearings 702 can be, for example, two. The two bearings 702 are respectively sleeved on the upper and lower ends of the outer shaft 3. The outer shaft end cap 703 is disposed at the bottom of the bearing 702 located at the lower end of the outer shaft 3, for fixing the bearing 702 and the outer shaft 3.

[0044] Preferably, such as Figures 1 to 7 As shown, in this embodiment, a second sealing assembly 8 is provided at the end of the support base 701 near the stirring blade 1. The second sealing assembly 8 may include a second waterproof seal 801 and a third sealing ring 802. The third sealing ring 802 is disposed between the main shaft 2 and the support base 701, and the second waterproof seal 801 is disposed at the end of the third sealing ring 802 near the stirring blade 1. The second waterproof seal 801 may be, for example, formed as an umbrella-shaped waterproof ring to provide waterproofing, and the third sealing ring 802 may be, for example, formed as a lip-shaped sealing ring to achieve secondary sealing. The first sealing assembly 6 and the second sealing assembly 8 together achieve secondary sealing of the entire structure.

[0045] Preferably, such as Figure 7As shown in the embodiment, the surface of the main shaft 2 is provided with a keyway 201, and the outer shaft 3 is connected to the keyway 201 via a pin 202. The pin 202 on the main shaft 2 can drive the outer shaft 3 to rotate, realizing the synchronous movement of the stirring paddle. In addition, due to the cooperation between the pin 202 and the keyway 201, the lifting range of the main shaft 2 is within the length range of the keyway 201 when it is raised or lowered, and the pin 202 also plays a guiding role.

[0046] Preferably, such as Figures 1 to 4 As shown, in this embodiment, a first groove is formed at the first end of the guide sleeve 403, and a second groove is formed at the second end of the guide sleeve 403. The first groove and the second groove are arranged back to back. The guide sleeve 403 is sleeved on one end of the lifting rod 402 through the first groove, and the guide sleeve 403 abuts against the second end of the steel ball control lever 404 through the second groove. When the main shaft 2 rotates, the guide sleeve 403 rotates together with the main shaft 2. Preferably, the guide sleeve 403 can be formed into a cylindrical structure, and the side of the cylindrical structure extends outward to form a protrusion. The protrusion can cooperate with the slot formed by the reducer 902 described below to achieve rotation with the main shaft 2. Preferably, the guide sleeve 403 can be made of a material with a low coefficient of friction, such as polytetrafluoroethylene, which can effectively reduce the torque transmitted to the lifting rod 402, ensure the stable working conditions of the lifting rod 402 (with anti-rotation structure), and improve the service life of the lifting cylinder 401.

[0047] Preferably, such as Figures 1 to 4 As shown, in this embodiment, the stirring paddle with lifting and locking functions may further include a power assembly 9. The power assembly 9 may include a motor 901 and a reducer 902. The motor 901 is connected to the reducer 902, which is located at the end of the main shaft 2 away from the stirring blade 1. The motor 901 may be, for example, an asynchronous motor of model YBVP-250, and the reducer 902 may be, for example, a reducer of model WKAF87. The reducer 902 can be fixedly connected to the support base 701 via a connecting cover 903.

[0048] This stirring paddle, equipped with lifting and locking functions, features a main shaft 2 and an outer shaft 3 designed separately. When it is raised, only the main shaft 2 moves, while the bearings fitted onto the outer shaft 3 do not need to move simultaneously. Furthermore, different bearings can be selected according to the specific model of the outer shaft 3, resulting in precise overall workmanship and meeting the needs of both large and small stirring devices.

[0049] The working process of the stirring paddle with lifting and locking functions is as follows: The main shaft 2 is rotated by the power component 9. The support base 701 is used to fix the stirring paddle with lifting and locking functions and is fixedly connected to the pot body 10 and the reducer 902. The stirring blade 1 is located inside the pot body 10 and can stir the materials inside the pot body 10. During cleaning, the main shaft 2 is lifted by the lifting component. When lifted, the steel ball control lever 404 unlocks and locks the steel ball 407. The main shaft 2 drives the stirring blade 1 to rise, so that the operator can clean the bottom of the pot body 10 without disassembling the stirring blade 1. During the cleaning process, due to the first sealing component 6 and the second sealing component 8, even if the liquid in the pot body 10 flows down, it will not enter the interior of the stirring paddle, ensuring the overall seal. After cleaning, the main shaft 2 is reset by the reset component 5. At the same time, the steel ball control lever 404 is also reset and axially locked with the locking steel ball.

[0050] The stirring paddle with lifting and locking functions can raise and lower the main shaft through the cooperation of the main shaft and the outer shaft. When raised, the structure can be sealed by the first sealing component, and when lowered, it can be locked by the locking component. The stirring paddle with lifting and locking functions can clean the root area of ​​the stirring paddle without removing the stirring paddle blades, making cleaning convenient, achieving cleaning and improving work efficiency.
