Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to an anti-vibration mixer. Background Art

[0002] The stability of the mixer's operation will be affected by the processing accuracy and installation accuracy of the parts. When the mixing drum is driven alone, the mixer runs smoothly. When the high-speed rotor in the mixing drum is driven alone, the mixer can also run smoothly. When the mixing drum and the high-speed rotor in the mixing drum are driven at the same time, since the high-speed rotor in the mixing drum and the mixing drum are supported by cantilever beams. When the high-speed rotor in the mixing drum and the mixing drum rotate at the same time, the mixing drum is affected by centrifugal force during the rotation process, and the contact part between the mixing drum and the sealing ring is more likely to have uneven friction, and the mixer will produce more obvious vibrations.

[0003] Existing equipment solves the above problems by improving the processing accuracy and installation accuracy of parts and reducing the accumulated errors when installing the various parts of the mixer. However, the overall installation accuracy of the mixer is high and the fault tolerance is poor. Some equipment still vibrates significantly during use, and the shock-absorbing effect is not obvious. Therefore, an anti-vibration mixer is proposed to solve the above problems. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1 and Figure 2 As shown, a vibration-proof mixer comprises: a frame 1, a sealing cover 4, a sealing ring 6 and a shock-absorbing mechanism.

[0028] A sealing cover, the sealing cover is rotatably connected to the frame, and a stirring component is arranged on the sealing cover, the stirring component is used to stir the material in the mixing barrel

[0029] The frame is rotatably provided with a mixing barrel, wherein a driving member (not shown in the figure) is provided on the frame 1, wherein the driving member is arranged at the lower part of the frame 1, wherein the mixing barrel 3 is rotatably connected to the frame 1 through a rotary bearing (not shown in the figure), and a driven shaft is arranged at the bottom of the mixing barrel 3, preferably, the output end of the driving member is connected to the driven shaft through a first gear set (not shown in the figure), the driven shaft is coaxially arranged with the mixing barrel 3, the output end of the driving member is meshed and connected to the first gear set, the first gear set is meshed and connected to the driven shaft, the driving member drives the driven shaft to rotate, and the rotating shaft drives the mixing barrel 3 to rotate. Of course, the driving member can also be connected to the driven shaft by belt transmission, thereby driving the mixing barrel 3 to rotate.

[0030] The right side of the frame 1 is rotatably connected to the sealing cover 4 through the support frame 16, and the sealing cover 4 is provided with a stirring assembly 5. By lifting the support frame 16, the sealing cover 4 can be separated from the mixing barrel 3, so as to facilitate the cleaning of the mixing barrel 3, the sealing cover 4 and the stirring assembly 5. In addition, the stirring assembly 5 is arranged on the bottom surface of the sealing cover 4, and is mainly used to stir the materials in the mixing barrel 3.

[0031] In one embodiment of the utility model, a sealing ring 6 is sleeved on the outer peripheral side of the sealing cover 4, and the inner wall of the sealing ring 6 is tightly fitted with the outer wall of the sealing cover 4. The sealing ring 6 is fixed to the outer peripheral side of the sealing cover 4 by screws. After the sealing cover 4 is docked with the mixing barrel 3, the outer wall of the sealing ring 6 is rotatably connected to the inner wall of the mixing barrel 3 to prevent material spillage and leakage. When the mixing barrel 3 rotates, the sealing cover 4 and the sealing ring 6 are both in a stationary state, and the sealing ring 6 serves as a rotating connection component between the sealing cover 4 and the mixing barrel 3.

[0032] like Figure 3 As shown, the shock absorbing mechanism includes: a mounting seat 7, the mounting seat 7 is connected to the frame 1 through a bolt rod, wherein the mounting seat 7 is rotatably connected to a rotating shaft 8, a driven roller 9 is sleeved on the rotating shaft 8, and the outer peripheral side of the driven roller 9 abuts against the outer peripheral side of the mixing cylinder 3. When the mixing cylinder 3 rotates at a high speed, the driven roller 9 applies a certain supporting force to the position where the mixing cylinder 3 and the sealing ring 6 match, thereby reducing the vibration amplitude of the mixing cylinder 3 and the sealing ring 6, and playing a role in stabilizing the mixing cylinder 3.

[0033] During operation, after adding materials into the mixing drum 3, the sealing cover 4 is docked at the port position of the mixing drum 3, wherein the inner wall of the sealing ring 6 is tightly fitted with the outer wall of the sealing cover 4, and the outer wall of the sealing ring 6 is rotatably connected to the inner wall of the mixing drum 3. While the stirring assembly 5 rotates at high speed, the driving member drives the mixing drum 3 to rotate at high speed. During the high-speed rotation of the mixing drum 3, the driven roller 9 abuts against the outer peripheral side of the mixing drum 3 and applies a certain supporting force to the position where the mixing drum 3 and the sealing ring 6 cooperate, so that the contact part of the mixing drum 3 and the sealing ring 6 has uniform friction, and the vibration generated between the mixing drum 3 and the sealing ring 6 is minimized while the material in the mixing drum 3 is efficiently stirred.

[0034] In one embodiment of the utility model, bearing seats 10 are symmetrically arranged on both sides of the mounting seat 7, and bearings 11 are arranged in the two bearing seats 10, wherein the outer peripheral side of the bearing 11 is fixedly connected to the bearing seat 10, and the two bearings 11 are respectively sleeved and connected to the two ends of the rotating shaft 8. Since the mixing cylinder 3 has a certain supporting force on the driven roller 9 when rotating, the bearing seat 10 and the bearing 11 provide a certain supporting force for the rotating shaft 8; at the same time, when the rotating shaft 8 rotates, the friction resistance received by the rotating shaft 8 can be reduced as much as possible.

[0035] A first retaining ring 13 is set at one end of the rotating shaft 8, and the first retaining ring 13 is clamped and connected to the outer peripheral side of the rotating shaft 8. A nut 14 is set at the other end of the rotating shaft 8. The first retaining ring 13 and the nut 14 can fix the bearing 11, adjust the clearance of the bearing 11, and bear the axial force of the bearing 11, so that the bearing can be accurately installed in the bearing seat 10, thereby improving the stability of the rotating shaft 8 and the driven roller 9.

[0036] A bearing end cover 12 is arranged on the outer side of the bearing seat 10, and the bearing end cover 12 is snap-connected to the bearing seat 10. Furthermore, bolt holes are arranged on the bearing end cover 12, and the bearing end cover 12 is further sealed and connected to the outer side of the bearing seat 10 through bolt rods. On the one hand, the bearing end cover 12 can fix the bearing 11, adjust the clearance of the bearing 11, and bear the axial force of the bearing 11. On the other hand, the bearing end cover 12 can play a role of dustproof and sealing. In addition to being dustproof and sealing itself, it can also cooperate with the bearing seat 10 to seal the bearing 11.

[0037] An annular baffle 20 and a second baffle ring 15 are arranged on the rotating shaft 8, and the annular baffle 20 and the second baffle ring 15 are respectively arranged on both sides of the driven roller 9, wherein the annular baffle 20 is arranged below the driven roller 9, the top surface of the annular baffle 20 is rotationally matched with the bottom surface of the driven roller 9, and the bottom surface of the second baffle ring 15 is rotationally matched with the top surface of the driven roller 9, and the annular baffle 20 and the second baffle ring 15 simultaneously play a certain axial limiting role on the driven roller 9 to prevent the driven roller 9 from moving left and right on the rotating shaft 8.

[0038] It should be noted that the driven roller 9 is made of elastic material. Under the premise of ensuring that the driven roller 9 has a certain elastic deformation, the hardness of the elastic material is relatively large, that is, the elastic coefficient is large enough. When the driven roller 9 supports the mixing cylinder 3, it can reduce the vibration amplitude of the mixing cylinder 3 and also have a good shock-absorbing and buffering effect.

[0039] Preferably, the elastic material is preferably a rubber material. The rubber material has high wear resistance and can effectively extend the service life of the driven roller 9. On the other hand, the driven roller 9 made of rubber material also has a large elastic coefficient, which is more in line with the requirements for the material of the driven roller 9.

[0040] The stirring assembly 5 includes: a stirring shaft 501, which is rotatably connected to the bottom surface of the sealing cover 4, wherein the stirring shaft 501 passes through the sealing cover 4, and a rotating bearing is arranged at the connection position between the stirring shaft 501 and the sealing cover 4, and the arrangement of the rotating bearing effectively reduces the friction between the stirring shaft 501 and the sealing cover 4, and improves the transmission efficiency of the stirring shaft 501. In addition, a plurality of first stirring blades 502 are arranged in an array on the outer peripheral side of the stirring shaft 501, and the first stirring blades 502 are used to stir the materials in the mixing barrel 3.

[0041] It should be noted that the rotation direction of the stirring shaft 501 is opposite to that of the mixing drum 3. When the mixing drum 3 drives the internal materials to rotate, the first stirring blade 502 can stir the materials in the mixing drum 3 to mix the materials.

[0042] A support frame 16 is provided on one side of the sealing cover 4, one end of the support frame 16 is hingedly connected to the frame 1, and the other end of the support frame 16 is connected to the sealing cover 4. When the sealing cover 4 needs to be opened, the support frame 16 is lifted, and the sealing cover 4 is synchronously lifted upward and separated from the mixing barrel 3. Preferably, the other end of the support frame 16 is directly fixed to the sealing cover 4 by bolts, which is convenient for later maintenance and disassembly, and the specific position of the sealing cover 4 can be adjusted according to the situation, and the flexibility is high.

[0043] Of course, the other end of the support frame 16 can also be directly fixed to the sealing cover 4 by welding, so that the sealing cover 4 will not become loose or move due to long-term use, and the overall stability of the mixer will be better during operation.

[0044] A driving motor 17 is provided on the top surface of the support frame 16, and the output end of the driving motor 17 is connected to the stirring shaft 501. When the support frame 16 is lifted, the sealing cover 4 and the driving motor 17 move synchronously. The support frame 16, the sealing cover 4, the stirring assembly 5 and the driving motor 17 can be regarded as a whole. When the sealing cover 4 is separated from the mixing barrel 3, the transmission connection between the driving motor 17 and the stirring assembly 5 is not damaged, and the overall structural design is scientific and reasonable.

[0045] Preferably, the output end of the driving motor 17 is connected to the stirring shaft 501 by means of a belt drive, a driving pulley (not shown in the figure) is arranged at the output end of the driving motor 17, a driven pulley (not shown in the figure) is arranged at the top end of the stirring shaft 501, the driving pulley and the driven pulley (not shown in the figure) are connected by a transmission belt, and the driving motor 17 drives the stirring shaft 501 by means of a belt drive.

[0046] Of course, the output end of the driving motor 17 may also be connected to the stirring shaft 501 through a gear meshing transmission mode, and the transmission connection form between the driving motor 17 and the stirring shaft 501 is not limited.

[0047] A driving cylinder 2 is arranged on both sides of the frame 1, wherein the driving cylinder 2 is vertically arranged on the frame 1, and the upper end of the driving cylinder 2 is hingedly connected to the middle part of the support frame 16 through a piston rod. When the sealing cover 4 needs to be separated from the mixing barrel 3, the driving cylinder 2 drives the piston rod to extend, and the piston rod pushes the support frame 16 upward, and one end of the support frame 16 drives the sealing cover 4 to move upward, so as to separate the sealing cover 4 from the mixing barrel 3. In addition, when the sealing cover 4 needs to be docked with the mixing barrel 3, the driving cylinder 2 can drive the support frame 16 to move downward by retracting the piston rod.

[0048] A stirring rod 18 is provided on the bottom surface of the sealing cover 4, wherein the stirring rod 18 is fixedly connected to the sealing cover 4. When the mixing drum 3 rotates relative to the sealing cover 4, the stirring rod 18 can assist the stirring assembly 5 in stirring the materials in the mixing drum 3. In addition, a second stirring blade 19 is provided at the bottom end of the stirring rod 18, and the bottom surface of the second stirring blade 19 is arranged parallel to the bottom surface of the inner wall of the mixing drum 3, and the second stirring blade 19 is as close as possible to the inner wall of the mixing drum 3, which can scrape the bottom of the mixing drum 3, so that the materials in various places in the mixing drum 3 can be evenly mixed and stirred.

[0049] When the utility model is used, after the sealing cover 4 is docked at the port position of the mixing barrel 3, the driving member drives the mixing barrel 3 to rotate at a high speed, and the first stirring blade 502 and the second stirring blade 19 begin to stir the material in the mixing barrel 3. While the mixing barrel 3 rotates at a high speed, the driving motor 17 drives the stirring shaft 501 to rotate at a high speed, and the first stirring blade 502 further accelerates the stirring speed of the material in the mixing barrel 3 until the material stirring is completed.

[0050] In summary, when the stirring assembly 5 and the mixing drum 3 rotate at high speed at the same time, the driven roller 9 abuts against the outer peripheral side of the mixing drum 3 and applies a certain supporting force to the position where the mixing drum 3 and the sealing ring 6 match, so that the concentricity of the mixing drum 3 and the sealing ring 6 is within an allowable fluctuation range, and the contact part of the mixing drum 3 and the sealing ring 6 has uniform friction, which effectively reduces the vibration generated between the mixing drum 3 and the sealing ring 6.

[0051] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0052] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
