Description

Technical Field

[0001] This utility model relates to the field of glass manufacturing equipment technology, and in particular to a glass manufacturing agitator with variable pitch stirring blades. Background Technology

[0002] In the glass manufacturing process, to ensure the uniformity of the glass melt's composition and eliminate streaks, a stirrer is typically used to forcibly agitate the high-temperature molten glass. The stirrer is a key piece of equipment in the glass homogenization process.

[0003] Existing glass manufacturing stirrers typically rely on the rotation of stirring blades to propel and mix molten glass. However, the temperature and viscosity of molten glass change continuously at different stages of melting and refining.

[0004] The inventors discovered in practice that many current agitators have a fixed blade angle. This fixed blade pitch design prevents the agitator from adjusting its stirring strategy based on the real-time viscosity of the molten glass. For example, at higher molten glass viscosities, a larger angle of attack is needed to generate sufficient stirring force, while at lower viscosities, the same angle of attack can lead to excessive shearing or energy consumption. This lack of flexibility results in poor adaptability of the agitator under different operating conditions, thus affecting stirring efficiency and the final homogeneity of the glass product.

[0005] Therefore, this invention proposes a glass-manufactured stirrer with variable-pitch stirring blades to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a glass manufacturing stirrer with variable pitch stirring blades, which aims to improve the problem that some glass manufacturing stirrers in the prior art have fixed stirring blade angles, making it impossible to adjust the stirring strategy according to the viscosity changes of the molten glass at different stages, resulting in reduced stirring efficiency.

[0007] This utility model provides a glass manufacturing stirrer with variable pitch stirring blades, including: a housing, a power supply unit installed inside the housing, and blades; and a lifting mechanism installed inside the housing and electrically connected to the power supply unit.

[0008] The lifting mechanism includes a transmission rod, a double-stayed rack, a gear, a rotating rod, a support rod, and a lifting assembly.

[0009] One end of the transmission rod is used to receive power from the power source.

[0010] Regarding the connection and assembly of the components, the double-stayed rack is connected to the other end of the transmission rod; the gear meshes with the double-stayed rack; the rotating rod is driven to rotate by the gear; the first support rod is pushed by the rotating rod; and the lifting assembly is connected to the first support rod.

[0011] The lifting assembly includes a lifting body, a rotating ring, and a second support rod. The lifting body is connected to the first support rod to perform lifting and reciprocating motion. The lifting body contacts the rotating ring through the rod, and the rotating ring drives the second support rod. The second support rod is connected to the blades and drives the blades. Preferably, the lifting mechanism also includes a limiting rod, which is used to limit the movement trajectory of the first support rod. This structure ensures that the first support rod moves stably along the preset trajectory during transmission, thus improving transmission accuracy.

[0012] Preferably, it also includes a rotating body, with the outer shell fixedly connected to the rotating body, so that the entire stirrer unit, including the lifting mechanism, can rotate together with the rotating body to perform the stirring task.

[0013] Preferably, it also includes a locking mechanism, which is used to connect and fix the lifting mechanism and the rotating body to ensure that there is no relative loosening between the two during rotation and pitch change.

[0014] Preferably, the locking mechanism includes a locking body, a shaft body, and a pin. The locking body is connected to the rotating body, and the shaft body can be inserted into the locking body to achieve the locking function through mechanical cooperation with the pin.

[0015] Preferably, the shaft body is provided with a first pressure plate and a second pressure plate. The first and second pressure plates are used to selectively pass through the pin, and the locking state or the unlocking state can be achieved by pushing and pulling the shaft body.

[0016] Preferably, the locking mechanism further includes a spring that elastically holds the pin in place, allowing it to remain in a fixed initial position when not in operation, preparing it for the next locking or unlocking.

[0017] Preferably, the locking mechanism further includes a washer, which is disposed on the pin to reduce friction and wear of the pin during movement and extend its service life.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting up a lifting mechanism, utilizes the linkage of the power supply main body to drive the transmission rod, double stationary rack, gear, rotating rod, support rod and lifting assembly, and finally drives the blade to swing and change pitch. This solves the problem in the prior art that the blade angle of the glass manufacturing stirrer is fixed and cannot be adjusted according to the change of the viscosity of the melt. It achieves the technical effect of being able to flexibly adjust the stirring angle, thereby improving the stirring efficiency and homogeneity.

[0019] 2. This utility model solves the problem of unstable linkage movement trajectory during transmission by setting a limiting rod in the lifting mechanism to limit the movement trajectory of the support rod, thereby achieving the technical effect of ensuring stable movement of the support rod and improving the accuracy of the lifting reciprocating motion of the lifting body.

[0020] 3. This utility model, by setting a locking mechanism, utilizes the cooperation between the first and second pressure plates on the shaft body and the pin, supplemented by springs and washers, to achieve the connection and fixation between the lifting mechanism and the rotating body. This solves the problem of unstable connection between the lifting mechanism and the rotating body during the operation of the agitator, and achieves the technical effects of reliable structural connection, convenient locking, reduced wear, and improved overall equipment stability.

The rotating rod 54 is driven to rotate by the gear 53. The first support rod 55 is pushed by the rotating rod 54. The lifting mechanism 5 also includes a lifting assembly 58, which includes a lifting body 581. The lifting body 581 is connected to the first support rod 55 and performs lifting and reciprocating motion. The lifting assembly 58 also includes a rotating ring 582 and a second support rod 583. The lifting body 581 contacts the rotating ring 582 through a rod. The rotating ring 582 drives the second support rod 583. The second support rod 583 is connected to the blade 57 to drive the blade 57 to swing and change pitch.

[0027] like Figure 4 As shown, the lifting mechanism 5 also includes a limiting rod 56, which is used to limit the movement trajectory of the support rod 55, ensuring that the support rod 55 moves stably along the preset trajectory when pushed by the rotating rod 54, thereby ensuring the accuracy of the lifting body 581's reciprocating motion.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The device also includes a rotating body 1, with a housing 2 fixedly connected to the rotating body 1. To achieve a stable connection between the lifting mechanism 5 and the rotating body 1, this embodiment also includes a locking mechanism 4. The locking mechanism 4 is used to connect and fix the lifting mechanism 5 and the rotating body 1. The locking mechanism 4 includes a locking body 41, which is connected to the rotating body 1. The locking mechanism 4 also includes a shaft body 42 and a pin 43. The shaft body 42 is used to insert into the locking body 41. The shaft body 42 is provided with a pressure plate 45 and a pressure plate 46. The pressure plate 45 and the pressure plate 46 are used to selectively pass through the pin 43 to lock or unlock. The locking mechanism 4 also includes a spring 44, which elastically holds the pin 43 to keep it in a fixed position. The locking mechanism 4 also includes a washer 47, which is provided on the pin 43 to reduce wear.

[0029] Reference Figure 4 The lifting mechanism 5 also includes a limiting rod 56, which is used to limit the movement trajectory of the support rod 55 and ensure that the support rod 55 moves stably along the preset trajectory.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The mechanism also includes a rotating body 1, with a housing 2 fixedly connected to the rotating body 1. It also includes a locking mechanism 4, which connects and fixes the lifting mechanism 5 to the rotating body 1. Specifically, the locking mechanism 4 includes a locking body 41 connected to the rotating body 1. The locking mechanism 4 also includes a shaft body 42 and a pin 43. The shaft body 42 is inserted into the locking body 41 to engage with the pin 43 for locking. The shaft body 42 is provided with a pressure plate 45 and a pressure plate 46, which selectively pass through the pin 43 to lock or unlock.

To reduce wear on the pin 43, the locking mechanism 4 also includes a washer 47, which is disposed on the pin 43.

[0031] The implementation principle of this application embodiment is as follows: When the power supply body 3 provides power to the lifting mechanism 5, the transmission rod 51 receives the power and drives the double stationary rack 52 to reciprocate. The gear 53 meshing with the double stationary rack 52 rotates accordingly. The gear 53 drives the rotating rod 54, and the rotating rod 54 pushes the first support rod 55. The first support rod 55 moves in the motion trajectory defined by the limit rod 56. The first support rod 55 is connected to the lifting body 581 in the lifting assembly 58, so that the lifting body 581 performs reciprocating motion of lifting. The lifting body 581 contacts and transmits motion to the rotating ring 582 through the rod. The rotating ring 582 drives the second support rod 583. The second support rod 583 is connected to the blade 57, which finally makes the blade 57 swing, completing the pitch change of the blade 57.

[0032] The locking mechanism 4 is used to connect and fix the lifting mechanism 5 and the rotating body 1. When locking, the shaft body 42 is inserted into the locking body 41, and the pressure plate 45 passes through the pin 43 to achieve locking. At this time, the spring 44 elastically holds the pin 43 to keep it in a fixed position. When it is necessary to release the lock, the shaft body 42 drives the pressure plate 46 to pass through the pin 43, and after contacting the pressure plate 45, it is pulled back, finally releasing the lock. The gasket 47 is set on the pin 43 to reduce wear. The outer shell 2 is fixedly connected to the rotating body 1 and is used to install the power supply body 3 and the lifting mechanism 5.
