Description

Technical Field

[0001] This utility model belongs to the field of mixers, and specifically relates to a mixer main shaft support rod with adjustable length. Background Technology

[0002] A mixer is a mechanical device that uses mechanical force and gravity to uniformly mix two or more materials. In existing technology, there is a paddle mixer, whose structure includes a machine body, a mixing chamber housed within the machine body, a rotating shaft within the mixing chamber, and paddles mounted on the shaft via support rods to form a rotor. Currently, the length of the support rods on the rotating shaft of these mixers is fixed. The optimal support rod length and paddle position differ for different types of materials to achieve the best mixing effect; however, the length of the support rods on the rotating shaft of current mixers cannot be adjusted. Utility Model Content

[0003] The purpose of this invention is to provide a mixer main shaft support rod with adjustable length, which can be adjusted and installed to adapt to different types of materials and optimize the mixing effect.

[0004] The purpose of this utility model is achieved as follows: A mixer spindle support rod with adjustable length includes a rotating spindle. Multiple mounting sleeves are arranged sequentially along the length direction on the rotating spindle. The mounting sleeves are fitted onto the rotating spindle. Each mounting sleeve is provided with a radial support rod. The support rod includes a fixed sleeve fixed to the mounting sleeve. An adjusting rod is inserted into the fixed sleeve. The fixed sleeve has several adjusting holes spaced apart along the length direction. The support rod has mounting holes. An adjusting bolt passes through the corresponding adjusting hole and mounting hole. A locking nut is fitted onto the end of the adjusting bolt. A stirring assembly is provided at the end of the support rod.

[0005] The rotating spindle of this invention is installed inside the mixer. The rotation of the spindle drives the stirring rod on the support rod to stir the material. When the length of the support rod needs to be adjusted, the locking nut is loosened, the position of the adjusting rod is moved axially, the adjusting bolt is passed through the corresponding adjusting hole of the fixing sleeve, and the locking nut is tightened to complete the adjustment of the support rod length. Compared with the prior art, the advantages of this invention are: it allows for adjustable installation of the support rod to adapt to different types of materials and optimizes the mixing effect.

[0006] As a further improvement of this utility model, the mounting sleeves are arranged at equal intervals. The mounting sleeves are fixed to the rotating spindle by screws.

[0007] As a further improvement of this utility model, the cross-section of the support rod is rectangular, and both the sleeve hole and the outer periphery of the fixing sleeve are rectangular. A row of equally spaced adjustment holes is provided on both the left and right walls of the fixing sleeve. Adjustment bolts are sequentially inserted through the adjustment hole on the left side of the fixing sleeve, the mounting hole, and the adjustment hole on the right side of the fixing sleeve. The locking nut presses against the right side wall of the fixing sleeve. The bolt seat of the adjustment bolt presses against the left side wall of the fixing sleeve.

[0008] As a further improvement of this utility model, each of the support rods is staggered circumferentially.

[0009] As a further improvement of this utility model, the stirring assembly includes a transverse stirring rod disposed at the end of the support rod, and a longitudinal stirring rod disposed on both the left and right sides of the middle of the transverse stirring rod. Both the transverse and longitudinal stirring rods are welded and fixed to the support rod, and the length of the longitudinal stirring rod is shorter than the length of the transverse stirring rod. The transverse and longitudinal stirring rods enhance the mixing effect.

[0010] As a further improvement of this utility model, an inclined reinforcing rod is welded and fixed to both the left and right sides of each of the longitudinal stirring rods, and the ends of the reinforcing rods are welded and fixed to the transverse stirring rods. The reinforcing rods serve to improve the strength of the transverse and longitudinal stirring rods. Attached Figure Description

Horizontal stirring rod; 11. Longitudinal stirring rod; and 12. Reinforcing rod. Detailed Implementation

[0017] like Figure 1-5As shown, a mixer spindle support rod with adjustable length includes a rotating spindle 1. Multiple mounting sleeves 2 are arranged sequentially along the length of the rotating spindle 1, and are fitted onto the rotating spindle 1. The mounting sleeves 2 are arranged at equal intervals. The mounting sleeves 2 are fixed to the rotating spindle 1 by screws. Each mounting sleeve 2 is provided with a radial support rod 3, and the support rods 3 are staggered circumferentially. The support rod 3 includes a fixing sleeve 4 fixed to the mounting sleeve 2. An adjusting rod 5 is inserted into the fixing sleeve 4. The fixing sleeve 4 has several adjusting holes 6 spaced apart along the length. The support rod 3 has mounting holes 7. An adjusting bolt 8 passes through the corresponding adjusting hole 6 and mounting hole 7. A locking nut 9 is fitted onto the end of the adjusting bolt 8. A stirring assembly is provided at the end of the support rod 3. The mixing assembly includes a transverse mixing rod 10 disposed at the end of the support rod 3, and a longitudinal mixing rod 11 disposed on both the left and right sides of the middle of the transverse mixing rod 10. Both the transverse mixing rod 10 and the longitudinal mixing rod 11 are welded and fixed to the support rod 3. The length of the longitudinal mixing rod 11 is less than the length of the transverse mixing rod 10. The transverse mixing rod 10 and the longitudinal mixing rod 11 enhance the mixing effect. An inclined reinforcing rod 12 is welded and fixed to both the left and right sides of each longitudinal mixing rod 11, and the end of the reinforcing rod 12 is welded and fixed to the transverse mixing rod 10. The reinforcing rod 12 serves to increase the strength of the transverse mixing rod 10 and the longitudinal mixing rod 11.

[0018] The cross-section of the strut 3 is rectangular, and the sleeve hole and outer periphery of the fixing sleeve 4 are also rectangular. A row of equally spaced adjusting holes 6 are provided on both the left and right walls of the fixing sleeve 4. Adjusting bolts 8 are sequentially inserted through the adjusting hole 6 on the left side of the fixing sleeve 4, the mounting hole 7, and the adjusting hole 6 on the right side of the fixing sleeve 4. Locking nuts 9 are tightened against the right side wall of the fixing sleeve 4. The bolt seat of the adjusting bolt 8 is tightened against the left side wall of the fixing sleeve 4.

[0019] The rotating spindle 1 of this invention is installed inside the mixer. The rotation of the spindle 1 drives the stirring rod on the support rod 3 to stir the materials. When the length of the support rod 3 needs to be adjusted, the locking nut 9 is loosened, then the position of the adjusting rod 5 is moved axially, and then the adjusting bolt 8 is passed through the corresponding adjusting hole 6 of the fixing sleeve 4. The locking nut 9 is then tightened to complete the adjustment of the length of the support rod 3. The advantage of this invention is that it allows for the adjustment and installation of the support rod 3 to accommodate different types of materials and optimize the mixing effect.
