(I)

[0031] Please refer to Figures 1 to 5 In order to prevent the existing mixing mixer with rotating shaft stirring structure from causing residue to stay in the sealing ring, causing the rotating shaft in the inner cavity to coke and other problems. The present application provides a shaft sleeve spiral sealing assembly 1 to replace the sealing ring of the existing structure, specifically, the shaft sleeve spiral sealing assembly 1 of the present application comprises: an outer shaft sleeve 11, a shaft end sealing sleeve 12, a spiral shaft sleeve 13, wherein the outer shaft sleeve 11 is sleeved outside the spiral shaft sleeve 13, the shaft end sealing sleeve 12 is connected with the first end of the outer shaft sleeve 11 to limit the spiral shaft sleeve 13 at least partially in the outer shaft sleeve 11, as shown in Figure 1 The first side of the spiral shaft sleeve 13 has a part of the sleeve body extending out of the shaft end sealing sleeve 12, wherein the outer wall of the spiral shaft sleeve 13 is provided with spiral blades 14, and the spiral blades 14 are defined as a spiral interval between the spiral blades 14 to define a material channel 15, wherein the material channel 15 is spiral to extend to the second end of the outer shaft sleeve 11.

[0032] Further, in the preferred embodiment, the inner ring of the shaft end sealing sleeve 12 is further provided with a sealing ring 16, which is arranged in a toothed or undulating shape to form a sealing effect with the first end of the spiral shaft sleeve 13, wherein the first end of the spiral shaft sleeve 13 is provided with a locking hole 17 for adapting with a screw 18, so that after the spiral shaft sleeve 13 is sleeved with the adapted rotating shaft 2, a locking is formed, and a limiting is formed at the first end of the shaft end sealing sleeve 12.

[0033] In addition, in order to further ensure that the residue entering the channel 15 can be discharged, the shaft end sealing sleeve 12 is further provided with an air channel 19, which is in communication with the channel 15 of the spiral shaft sleeve 13, so that the high-pressure air provided by an external air supply device such as an air compressor 24 can flush the channel 15, thereby effectively preventing the residue from remaining in the channel 15. In addition, even if the spiral shaft sleeve 13 rotates to drive the spiral of the channel 15, the air supply of the air channel 19 will not be affected, and a better chip removal effect can be achieved with the air entering the channel 15.

[0034] In a preferred embodiment, the spiral shaft sleeve 13 is provided with a closing ring 10, which forms a limit at the second end of the shaft end sealing sleeve 12. On the one hand, the closing ring 10 can block the residue in the channel 15 from flowing backward and even clogging the air channel 19. On the other hand, the closing ring 10 can form a limit for the shaft end sealing sleeve 12 with the screw 18 at the locking hole 17, thereby forming a firm assembly structure.

[0035] In another preferred embodiment, the closing ring 10 can be disc-shaped, which is arranged at the outlet of the air channel 19 to form a flow division for the incoming air. In this way, the air input by the air channel 19 can be divided into two air flows in opposite directions, which can prevent the residue in the channel 15 from flowing backward and being discharged, and also prevent foreign matter from entering the shaft end sealing sleeve 12. In this way, a two-way foreign matter discharge air resistance structure is formed.

[0036] In addition, in order to reduce the possibility of residue remaining in the channel 15 and also to better adapt to the air flow input by the air compressor 24 to reduce wind resistance, in this embodiment, the bottom of the channel 15 is arc-shaped and slot-shaped, which can reduce wind resistance and also reduce the residue dead angle of the channel 15 from the structure, thereby further ensuring that the residue will not remain in the channel 15.

[0037] In this way, the shaft sleeve spiral sealing assembly 1 provided by the present application can effectively prevent the residue from remaining in the sealing ring, avoid the material residue from staying in the sealing ring for a long time to cause coking due to friction and heat, thereby improving the production stability of such mixing and stirring machines, eliminating safety hazards, and further improving the service life of the equipment. (II)

[0039] Please refer to Figures 1 to 6To achieve the above object, according to another aspect of the present application, there is provided a mixing blender, comprising a mixing box 21, a blender 22, a driving unit 23, an air compressor 24, and a shaft sleeve sealing assembly 1, wherein the shaft sleeve sealing assembly 1 comprises an outer shaft sleeve 11, a shaft end sealing sleeve 12, and a helical shaft sleeve 13, the outer shaft sleeve 11 is sleeved on the helical shaft sleeve 13, the shaft end sealing sleeve 12 is connected with the first end of the outer shaft sleeve 11 to limit the helical shaft sleeve 13 to be at least partially located in the outer shaft sleeve 11, the helical shaft sleeve 13 is provided with helical blades 14, and the helical blades 14 are spaced apart to define discharge channels 15, the discharge channels 15 are communicated with the mixing box 21, the shaft end sealing sleeve 12 is further provided with air channels 19, the air channels 19 are communicated with the discharge channels 15 and the air compressor 24, the second end of the outer shaft sleeve 11 is fixed at a driving port of the mixing box 21, the driving end of the blender 22, i.e., the rotating shaft 2, is sleeved on the helical shaft sleeve 13 and is drivingly connected with the driving unit 23 to form a helical stirring structure, and in addition, it is to be noted that the driving unit 23 preferably comprises a driving motor 231 and a bearing support 232, the bearing support 232 is used to support the rotating shaft 2 of the driving end of the blender 22 at a predetermined position so that the helical shaft sleeve 13 can be located in the coaxial position of the outer shaft sleeve 11.

[0040] Thus, the rotating shaft 2 of the driving end of the blender 22 is drivingly connected with the driving motor 231 through the bearing support 232 to ensure that the helical blades 14 on the helical shaft sleeve 13 can always normally operate in the running state.

[0041] The inner ring of the shaft end sealing sleeve 12 is provided with a sealing ring 16, the sealing ring 16 is arranged in a toothed manner to be matched with the first end of the helical shaft sleeve 13, it is to be noted that the sealing ring 16 is designed to prevent external dust and garbage from entering the outer shaft sleeve 11 and to prevent the gas blown by the air compressor 24 from leaking outward, thereby stabilizing the gas pressure of the air compressor 24 to the discharge channels 15, the first end of the helical shaft sleeve 13 is provided with a locking hole 17 to be matched with a screw 18, and the first end of the shaft end sealing sleeve 12 is limited. In addition, the helical shaft sleeve 13 is provided with a closing ring 10, and the closing ring 10 is limited at the second end of the shaft end sealing sleeve 12.

[0042] Wherein in the working state of the mixing blender, the screw shaft sleeve 13 is locked and fixed with the transmission shaft following the blender 22 by the screw 18 to form synchronous rotation, and the screw blade 14 can be set according to the left and right positions of the transmission shaft to make the screw feeding direction always towards the mixing box 21, so that when the blender 22 brings the material residues into the gap between the screw shaft sleeve 13 and the outer sleeve 11, the material residues will always be sent back into the mixing box 21 by the screw rotation of the material channel 15 of the screw shaft sleeve 13, thereby avoiding the residues between the screw shaft sleeve 13 and the outer sleeve 11, forming coking and other problems.

[0043] In addition, according to the characteristics and process requirements of the stirred material, sometimes there are problems such as large residue viscosity or large residue particle size, which can easily cause the material channel 15 to be blocked or to be retained in the material channel 15. At this time, the air compressor 24 can continuously or at a preset interval frequency and air pressure blow air into the material channel 15, thereby dredging the material channel 15 and returning the material residues into the mixing box 21, thereby ensuring that all types of material residues cannot be retained in the material channel 15 for a long time to form coking, thereby stabilizing the equipment operation.

[0044] In the preferred embodiment, in order to reduce the possibility of residue remaining in the material channel 15 and also better adapt to the air flow input by the air compressor 24 to reduce wind resistance, the bottom of the material channel 15 is in the form of an arc-shaped groove, thereby reducing wind resistance on the one hand and also reducing the residue dead angle of the material channel 15 from the structure to further ensure that the material channel 15 will not retain residues.

[0045] In summary, the mixing blender provided by the present application can effectively prevent residues from being retained in the sealing ring and avoid material residues from being retained in the sealing ring for a long time to generate heat through friction and cause coking, thereby improving the production stability of such mixing blenders, eliminating safety hazards, and further improving the service life of the equipment.
