[0053] Reference Figure 1-Figure 3 , the embodiment of the present application provides a tumbling mixer, comprising:

[0054] Two support frames 1 are arranged at intervals, and a lower crossbeam 2 is connected between the two support frames 1;

[0055] Two guide plates 3 are arranged on the lower cross beam 2, and a receiving area is formed between the two guide plates 3;

[0056] A material rack 4, the bottom of which is provided with casters 9; and

[0057] The hopper 5 is arranged on the material frame 4, and a guide frame 6 is arranged at the bottom of the hopper 5. The extension direction of the guide frame 6 is parallel to the extension direction of the lower cross beam 2, and positioning wheels 7 are rotatably arranged at both ends thereof. The two positioning wheels 7 are respectively used for guiding and cooperating with the two guide plates 3 to set the hopper 5 in the accommodating area.

[0058] The support frame 1 can be fixed on the ground by welding or screwing to provide support for other mechanisms. The casters 9 on the material rack 4 make the material rack 4 movable, so that the hopper 5 on the material rack 4 can be pushed to any specified position. By setting positioning wheels 7 on the guide frame 6 of the hopper 5, the two positioning wheels 7 cooperate with the two guide plates 3 respectively, and the positioning wheels 7 drive the overall deflection and positioning of the material rack 4 under the action of the guide plates 3, so that the material rack 4 can be stably pushed into the accommodating area between the two guide plates 3 during the movement, ensuring the accurate positioning of the hopper 5, facilitating work operations, and effectively avoiding the problem that the material rack 4 hits the guide plate 3, resulting in the material rack 4 being unable to be pushed, and the hopper 5 needs to be repeatedly pulled out and pushed in to adjust the entry posture of the hopper 5, thereby reducing labor intensity and ensuring production efficiency.

[0059] A manual valve 8 is also provided on the guide frame 6. A handle for convenient valve switching is provided on the manual valve 8. The manual valve 8 is screwed to the bottom of the guide frame 6. In addition, the positioning wheel 7 is also screwed to the guide frame 6. The positioning wheel 7 can roll flexibly. On the one hand, it serves as a guide when the hopper 5 is manually pushed in, reducing repeated alignment. On the other hand, since the mounting holes of the manual valve 8 on the guide frame 6 and the mounting holes of the positioning wheel 7 are made integrally with the guide frame 6, the size is easy to ensure. No matter whether the manufacturing or installation deviation of the hopper 5 and the material frame 4 occurs, it will not affect the positional relationship between the positioning wheel 7 and the manual valve 8. Therefore, when the hopper 5 with materials enters the next process for unloading after the material mixing is completed, the positioning mechanism on the unloading station can accurately position the manual valve 8 and the handle, so that the automatic valve opening mechanism can accurately turn the valve of the manual valve 8 to achieve the purpose of stable unloading.

[0060] Reference Figure 1-Figure 3 In some embodiments, the material rack 4 includes two first frames 41 spaced apart, a second frame 42 is connected between the two first frames 41, both ends of the guide frame 6 are aligned with the two first frames 41 respectively, and guide wheels 18 are rotatably provided on the two first frames 41. The guide wheels 18 are screwed and installed on the first frames 41 and can roll flexibly. The guide wheels 18 are used in conjunction with the positioning wheels 7 to reduce repeated alignment when the hopper 5 is pushed in.

[0061] The casters 9 include fixed casters 91 and universal casters 92, wherein two fixed casters 91 are provided, and two universal casters 92 are provided, and both fixed casters 91 and universal casters 92 are screwed and installed at the bottom of the material rack 4, so as to realize the reliability and stability of the movement of the material rack 4. Specifically, the two universal casters 92 are respectively connected to the two ends of the second frame 42, and the two fixed casters 91 are respectively connected to the ends of the two first frames 41 away from the second frame 42.

[0062] The first frame 41 and the second frame 42 are both fixedly provided with a vertical rod 43, and the other end of the vertical rod 43 is used to abut against the outer edge of the hopper 5. A plurality of vertical rods 43 are evenly spaced along the circumference of the hopper 5 to ensure the stability of the support for the hopper 5. The abutting connection makes it easy to take or place the hopper 5 on the vertical rod 43, and the hopper 5 can also be replaced to adapt to different hoppers 5 to improve the versatility of the rack 4. Of course, in order to ensure the reliability and safety of the hopper 5, the hopper 5 is welded on the vertical rod 43, and the hopper 5 is stably supported by a plurality of vertical rods 43.

[0063] Reference Figure 1 In some embodiments, the two guide plates 3 are movably arranged on the lower cross beam 2 along the extension direction of the lower cross beam 2, and are fixed by a movably arranged locking member. The lower cross beam 2 is provided with a plurality of waist-shaped holes spaced apart along its own extension direction, and the guide plates 3 are screwed to the waist-shaped holes of the lower cross beam 2, and the guide plates 3 can move along the extension direction of the lower cross beam 2. The locking member includes a screw or a bolt, etc. The guide plates 3 are screwed to the waist-shaped holes at the corresponding positions through the locking member to achieve the fixing of the guide plates 3, and the fixed guide plates 3 can guide the hopper 5.

[0064] The tumble mixer also includes a stirring mechanism 10, and an upper crossbeam 11 is also connected between the two support frames 1, and the upper crossbeam 11 is located above the upper crossbeam 11, and a cover 16 is provided on the upper crossbeam 11, and the stirring mechanism 10 is arranged above the cover 16, and the bottom of the cover 16 is used to cooperate with the hopper 5; wherein the cover 16 is a cylindrical structure that is arranged through the top and bottom, and the stirring mechanism 10 is located above the cover 16. It should be noted that the stirring mechanism 10 in the embodiment of the present application can adopt any stirring mechanism 10 in the existing mixer, and this embodiment has no structural improvement on the stirring mechanism 10, so as to achieve the stirring effect. As an example, the stirring mechanism 10 includes a stirring motor, a stirring shaft and a stirring blade, the stirring motor is installed on the cover 16 by flange screw connection, the stirring shaft and the stirring blade are installed on the motor shaft of the stirring motor, and the stirring blade can be moved to the inside of the cover 16 to stir the material inside.

[0065] Reference Figure 1-Figure 5An upper crossbeam 11 is also connected between the two support frames 1, and the upper crossbeam 11 is located above the upper crossbeam 11. The tumbling mixer also includes two sets of lifting and locking mechanisms 12, and the lifting and locking mechanisms 12 include:

[0066] A clamping jaw 121, wherein the cross-section of the clamping jaw 121 is arc-shaped and is coaxially arranged with the hopper 5, and the two clamping jaws 121 are axially symmetrically arranged about the central axis of the hopper 5 and are located on both sides of the hopper 5 in the radial direction; and

[0067] The driving assembly 122 has a movable end connected to the clamping jaw 121 to drive the clamping jaw 121 to move up and down.

[0068] The two clamps 121 clamp the opposite sides of the hopper 5, and the driving assembly 122 drives the clamps 121 to rise to drive the hopper 5 to rise synchronously until the top of the hopper 5 abuts against the bottom of the cover body 16, thereby realizing the alignment connection between the hopper 5 and the cover body 16, and the subsequent stirring operation can be performed through the stirring mechanism 10.

[0069] The driving assembly 122 includes a driver 1221 and an elastic member 1222, wherein the elastic member 1222 is arranged on the upper beam 11, and the connecting end of the driver 1221 passes through the elastic member 1222 and is connected to the upper beam 11; wherein the driver 1221 is used to drive the lifting and lowering of the clamping jaw 121, and the driver 1221 is screwed to the upper beam 11 through the elastic member 1222, wherein the driver 1221 can be a structure in which a cylinder or a motor and a screw rod cooperate, etc. Optionally, the driver 1221 adopts a screw motor, and the screw motor is screwed through the elastic member 1222 and installed on the upper beam 11, and the working drive of the screw motor drives the lifting and lowering of the screw rod connected thereto, and the clamping jaw 121 is connected to the screw rod of the screw motor to realize the lifting and lowering of the clamping jaw 121. When the screw motor moves to raise the screw to the predetermined position, the cover 16 and the hopper 5 are clamped. However, in fact, due to the gap in the mechanism and the vibration of the equipment, the cover 16 and the hopper 5 may still have the risk of poor sealing. At this time, the role of the elastic member 1222 is to provide a pre-tightening force to the clamping state of the clamping jaw 121 through the elastic deformation of the elastic member 1222, so as to further fix the cover 16 and the hopper 5. The elastic member 1222 can be any component with elastic properties, such as an elastomer or a disc spring.

[0070] The lifting and locking mechanism 12 further includes:

[0071] A guide frame 123 is disposed on the upper cross beam 11, and a guide hole 126 is formed through the guide frame 123, wherein the cross-sectional shape of the guide hole 126 is the same as the cross-sectional shape of the outer wall of the hopper 5; and

[0072] The guide arm 124 connects the movable end of the driving assembly 122 and the clamping jaw 121 , and a guide wheel 125 is disposed on the guide arm 124 , and the guide wheel 125 is rotatably disposed in the guide hole 126 .

[0073] The guide wheel 125 can roll in the guide hole 126 of the guide frame 123 to reduce friction, and through the cooperation between the guide wheel 125 and the guide hole 126, when the screw rod is raised or lowered, the clamping jaw 121 can only move along a predetermined trajectory under the limiting effect of the guide wheel 125.

[0074] In some embodiments, a plurality of limit members 13 are spaced apart on one side of the upper beam 11 toward the lower beam 2. The plurality of limit members 13 cooperate with the hopper 5 to limit the maximum moving distance of the material rack 4 after it moves to the accommodating area, thereby avoiding the situation where the material rack 4 moves into the accommodating area and then moves out of the accommodating area.

[0075] The screw motor drives the screw to rise or fall, and drives the clamping claw 121 connected to the screw to perform an upward or downward movement along the guide hole 126 of the guide frame 123 along a fixed trajectory. The elastic member 1222 between the screw motor and the cover body 16 can provide a continuous pre-tightening force to the entire lifting and locking mechanism 12 after the screw motor stops moving, so that the cover body 16 and the hopper 5 can be reliably sealed. On the one hand, the clamping claw 121 can lift up and clamp the hopper 5, and on the other hand, its arc-shaped structure is coaxial with the hopper 5, and its diameter is slightly larger than the diameter of the hopper 5, so that in the lifting process, it can cooperate with the positioning of the limit member 13 to make the hopper 5 more securely abutted.

[0076] Reference Figure 1-Figure 7 Optionally, a positioning assembly 14 is also provided on the cover body 16. The positioning assembly 14 includes a driving positioning member 141 and a positioning block 142. The positioning block 142 is connected to the lifting end of the driving positioning member 141. The driving positioning member 141 is provided on the cover body 16. The positioning block 142 is used to cooperate with the hopper 5. The positioning block 142 and the limiting member 13 are located on opposite sides of the hopper 5, so as to further limit the position of the hopper 5 through the mutual cooperation between the positioning block 142 and the limiting member 13. Among them, the driving positioning member 141 includes a cylinder or an electric push rod, etc. In this application, the driving positioning member 141 adopts a cylinder, and the positioning block 142 is connected to the piston rod of the cylinder, and the lifting and lowering of the positioning block 142 is driven by the extension and retraction of the cylinder piston rod.

[0077] The overturning mixer also includes a overturning mechanism 15, the movable end of which is connected to the upper beam 11 to drive the upper beam 11 to rotate; the overturning mechanism 15 drives the upper beam 11 to rotate to drive the cover body 16 to rotate synchronously, and under the action of the connection between the cover body 16 and the hopper 5, the hopper 5 is overturned synchronously with the rotation of the cover body 16, thereby improving the uniformity of material mixing in the hopper 5.

[0078] The flip mechanism 15 includes a flip motor 151, which is disposed on one of the support frames 1. The flip motor 151 is connected to the upper crossbeam 11 via a rotating shaft, and both ends of the rotating shaft can be rotatably disposed on the two support frames 1 via bearing seats. A plurality of electrical switches can also be disposed on the flip motor 151 to accurately control its rotation angle.

[0079] In some embodiments, the bottom of the cover 16 is provided with a lower flange 161, the top of the hopper 5 is provided with an upper flange 51, the lower flange 161 is provided with an annular sealing groove, and a sealing member is provided in the annular sealing groove; the sealing member is provided to seal the connection between the cover 16 and the hopper 5, thereby ensuring the sealing fit between the cover 16 and the hopper 5. In addition, by providing the upper flange 51 on the hopper 5, a clamping position can be provided for the clamping jaws 121, thereby further ensuring the reliability and stability of the clamping jaws 121 clamping the hopper 5.

[0080] In some embodiments, the flipping further includes an auxiliary clamping mechanism 17, and the auxiliary clamping mechanism 17 includes:

[0081] A power device 171 is disposed on the cover body 16;

[0082] A buckle 172, used for abutting against a side of the upper flange 51 away from the lower flange 161; and

[0083] The transmission assembly 173 connects the movable end of the power device 171 and the fastening member 172 to drive the fastening member 172 to rotate.

[0084] The power device 171 drives the rotation of the fastening member 172 through the transmission assembly 173 to further fix the hopper 5 and the cover body 16. The power device 171 includes an electric push rod or a power cylinder. The power device 171 in the present application adopts a power cylinder, which is arranged on the cover body 16. The transmission assembly 173 includes a first transmission plate and a second transmission plate. The first transmission plate is connected to the piston rod of the power cylinder. The second transmission plate is arranged at the bottom edge of the cover body 16. A first connecting rod is hinged between the first transmission plate and the fastening member 172, and a second connecting rod is hinged between the fastening member 172 and the second transmission plate; therefore, the extension and retraction of the piston rod of the power cylinder will drive the reciprocating swing of the fastening member 172, so that the fastening member 172 is clamped and matched with the upper flange 51 of the hopper 5.

[0085] Reference Figure 1-Figure 7In summary, in the tumble mixer provided by the present application, the hopper 5 containing the material to be mixed is manually pushed into the lower part of the cover 16, and the hopper 5 has been roughly positioned with the cover 16 through the guidance of the guide plate 3 and the limiting of the plurality of limiting members 13 distributed along the circumference on the rear side of the cover 16. Subsequently, the driving positioning member 141 of the positioning assembly 14 installed on the front side of the cover 16 is actuated to lower the positioning block 142 thereon, thereby further limiting the hopper 5. Next, the lifting and locking mechanism 12 is activated, and the clamping jaws 121 rise along a fixed trajectory to lift up the hopper 5, and the hopper 5 is corrected by the arc structure of the clamping jaws 121 until it abuts and clamps against the sealing ring of the lower flange 161 at the bottom of the cover body 16; because the current lifting and locking mechanism 12 is distributed on the left and right sides, in order to ensure that the front side of the abutment will not be detached due to the bending moment generated by its own weight when the hopper 5 is turned over, the auxiliary clamping mechanism 17 on the front side is activated at this time, and the bottom of the cover body 16 is turned down and clamped with the upper flange 51 of the hopper 5, so that the seal is more reliable. Then, the flipping motor 151 is started, and the rotating shaft drives the cover body 16 to rotate 180° counterclockwise; then, the stirring motor is started, and the stirring blades rotate rapidly to mix the materials evenly. After the preset mixing time is reached, the stirring motor stops, and the flipping mechanism 15 rotates 180° clockwise, and can be further rotated about 15° (the angle is set according to needs) to make the mixed material surface more uniform and reduce the material attached to the wall of the hopper 5. After a period of time is set to maintain this state, the flipping motor 151 drives the rotating shaft and the cover body 16 to rotate counterclockwise to a completely vertical position. These multiple stop positions are precisely controlled by several electrical switches installed on the side of the flipping motor 151; then the auxiliary clamping mechanism 17 is released, and the lifting and locking mechanisms 12 on both sides drive the screw rod to descend, thereby driving the clamping jaws 121 to descend, and the hopper 5 descends accordingly, completing the mixing of the materials in the hopper 5.
