[0034] Please refer to Figure 1 A blender includes an equipment rack 1, a first mounting part 2, a hoist motor 3, a second mounting part 4, a drive motor 5, a stirring shaft 6, and a controller 7.

[0035] The equipment rack 1 includes a base 1-1 and a rack body 1-2. The base 1-1 is concave and is used to be placed on the ground. After the material to be stirred is placed in the container, the container is placed in the recess of the base 1-1. The rack body 1-2 is fixedly connected to the middle position of the base 1-1.

[0036] Please refer to Figure 1 and Figure 5 , the first mounting part 2 is connected to the side of the frame 1-2 near the notch of the base 1-1 in a sliding manner. More specifically, a linear guide can be designed between the first mounting part 2 and the frame 1-2, or the first optical axis 2a can be designed as a guide rod between the first mounting part 2 and the frame 1-2. The frame 1-2 has a blocking part 1a for the first mounting part 2 to abut against. That is, when the first mounting part 2 abuts against the blocking part 1a, the lower limit position is reached.

[0037] Please refer to Figure 1 , the hoisting motor 3 is installed on the equipment frame 1 to drive the first mounting part 2 to move.

[0038] In some embodiments, the hoisting motor 3 is directly above the first mounting part 2. The steel wire rope 3a wound / unwound by the hoisting motor 3 is directly connected to the first mounting part 2.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the hoisting motor 3 is installed on the side of the frame 1-2 away from the notch of the base 1-1. Two fixed pulleys 1b and a resilient member 1c are arranged on the top of the frame 1-2. The two fixed pulleys 1b are used for the steel wire rope 3a of the hoisting motor 3 to pass through. The resilient member 1c makes the distance between the two fixed pulleys 1b tend to increase. More specifically, the frame 1-2 has two mounting blocks 1d; the resilient member 1c can act on the fixed pulley 1b near the hoisting motor 3, and the wheel seat of the fixed pulley 1b is fixedly provided with two second optical axes 1b1; the second optical axes 1b1 pass through and are slidingly connected to the two mounting blocks 1d, and a stop block is further fixedly arranged between the two mounting blocks 1d; the resilient member 1c is two compression springs, which are respectively sleeved on the two second optical axes 1b1, one end abuts against the stop block, and the other end abuts against the mounting block 1d away from the hoisting motor 3. The first mounting part 2 is provided with a movable pulley 2b for the steel wire rope 3a to pass through.

[0040] That is, the steel wire rope 3a of the hoisting motor 3 passes through the two fixed pulleys 1b and the movable pulley 2b, and is then fixedly connected to the frame 1-2. More specifically, the end of the steel wire rope 3a can be made into a loop by a U-shaped clamp, and the frame 1-2 is fixedly provided with a connecting pin for connecting the loop.

[0041] When the first mounting part 2 does not reach the lower limit position, in the side view direction, the steel wire rope 3a on both sides of the movable pulley 2b is vertical, the steel wire rope 3a between the two fixed pulleys 1b is horizontal, and the steel wire rope 3a between the fixed pulley 1b and the hoisting motor 3 is vertical. After the first mounting part 2 reaches the lower limit position, even if the hoisting motor 3 continues to unwind a part of the steel wire rope 3a and then stops, the steel wire rope 3a can be kept taut under the action of the resilient member 1c.

[0042] Referring to Figure 1 and Figure 5 The second mounting portion 4 is fixedly connected to the first mounting portion 2 and can be adjusted in the up-down direction. That is, the second mounting portion 4 can move up and down relative to the first mounting portion 2, and a limiting member for limiting the movement of the second mounting portion 4 is arranged between the two. In addition, the second mounting portion 4 is concave, and the position of the concave portion corresponds to the movable pulley 2b of the first mounting portion 2, without interfering with the steel wire rope 3a and the movable pulley 2b.

[0043] Referring to Figure 2 and Figure 5 In some embodiments, the first mounting portion 2 has two vertical first optical axes 2a. The two first optical axes 2a are used for sliding connection with the frame body 1-2 and for fixed connection of the second mounting portion 4. That is, the sliding connection between the first mounting portion 2 and the frame body 1-2 is achieved by using the above-mentioned method of designing the first optical axis 2a between the first mounting portion 2 and the frame body 1-2 as a guide rod. More specifically, a linear bearing matched with the first optical axis 2a can be fixedly connected to the top of the frame body 1-2.

[0044] Compared with a linear guide rail, the first optical axis 2a not only achieves the up-down sliding connection between the first mounting portion 2 and the frame body 1-2, but also conveniently provides a fixed connection for the second mounting portion 4. Correspondingly, the second mounting portion 4 can be adjusted in the fixed position by using a hand screw bolt 4a as a limiting member for limiting the movement of the second mounting portion 4. The second mounting portion 4 has a threaded hole for threaded connection of the hand screw bolt 4a, and the threaded hole is in communication with a through hole for the first optical axis 2a to pass through.

[0045] Referring to Figure 4 In some embodiments, a gear and rack mechanism is further arranged between the second mounting portion 4 and the first mounting portion 2. In combination with the above-mentioned embodiment of the first mounting portion 2 having two vertical first optical axes 2a, a plurality of notches can be formed on the first optical axis 2a to form a rack 2a1, and a gear 4b is rotatably connected to the second mounting portion 4 and engaged with the rack 2a1.

[0046] When the second mounting portion 4 needs to be adjusted in the fixed position, the hand screw bolt 4a is loosened, and the gear 4b is manually rotated to drive the second mounting portion 4 to move up and down relative to the first mounting portion 2.

[0047] Referring to Figure 1 The drive motor 5 is mounted on the second mounting portion 4.

[0048] The stirring shaft 6 is mounted on the output shaft of the drive motor 5.

[0049] The controller 7 is mounted on the frame body 1-2 and is used to control the hoist motor 3 and the drive motor 5.

[0050] In use, the container is first placed in the recess of the base 1-1, then the hoist motor 3 lowers the first mounting portion to abut against the blocking portion 1a, reaching the lower limit position, and the stirring shaft 6 extends into the container, then the second mounting portion 4 is adjusted up and down in the fixed position of the first mounting portion 2, i.e. the stirring shaft 6 is adjusted up and down in the container, finally the drive motor 5 is started, and the stirring shaft 6 rotates to stir the material in the container.

[0051] Referring to Figure 5 In some embodiments, the first mounting portion 2 is provided with a rotating block 2c at the bottom. The blocking portion 1a has a through slot 1a1 for the rotating block 2c to pass through. The rotating block 2c is used to limit the separation of the first mounting portion 2 and the blocking portion 1a when the first mounting portion 2 abuts against the blocking portion 1a. That is, when the first mounting portion 2 reaches the lower limit position, the rotating block 2c passes out of the through slot 1a1, and the top surface of the rotating block 2c and the bottom surface of the blocking portion 1a are in the same plane; the rotating block 2c is rotated to misalign the rotating block 2c and the through slot 1a1, so that the rotating block 2c cannot pass through the through slot 1a1, and the first mounting portion 2 cannot move upward, thereby maintaining abutment against the blocking portion 1a.

[0052] After the hoist motor 3 lowers the first mounting portion to abut against the blocking portion 1a, reaching the lower limit position, the rotating block 2c can be rotated to maintain the abutment of the first mounting portion 2 against the blocking portion 1a. During subsequent stirring, the first mounting portion 2 can be more stable.

[0053] Referring to Figure 6 In some embodiments, the rotating block 2c is a rotating handle of a rotary switch. More specifically, the bottom surface of the first mounting portion 2 can have a mounting slot 2d, and the seat body of the rotary switch is mounted in the mounting slot 2d, so that the bottom surface of the first mounting portion 2 can be attached to the blocking portion 1a, and the rotating handle of the rotary switch extends out of the mounting slot 2d. The rotary switch is connected to the drive motor 5, i.e. the rotary switch is connected in the circuit between the drive motor 5 and the controller 7. When the rotating block 2c limits the separation of the first mounting portion 2 and the blocking portion 1a, the drive motor 5 is in a connected state that can be started, i.e. the rotary switch is in a connected state at this time; when the rotating block 2c does not limit the separation of the first mounting portion 2 and the blocking portion 1a, the drive motor 5 is in a disconnected state that cannot be started, i.e. the rotary switch is in a disconnected state at this time.

[0054] During the lifting and lowering of the first mounting portion 2, the circuit between the drive motor 5 and the controller 7 is kept disconnected, and the drive motor 5 cannot be started to rotate the stirring shaft 6. After the first mounting portion is lowered to abut against the blocking portion 1a, reaching the lower limit position, the rotary switch also needs to be rotated to maintain the abutment of the first mounting portion 2 against the blocking portion 1a, so that the drive motor 5 can be started to rotate the stirring shaft 6. This improves the safety during operation.
