In addition, the present application can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or arrangements discussed.

[0053] Reference Figure 1 The application provides a mixing machine, which comprises a rack 100, a barrel member 200, a barrel cover member 300 and a stirring assembly 400.

[0055] The barrel cover member 300 is connected to the rack 100, and is used to open or close the mixing cavity.

[0056] The stirring assembly 400 is rotatably connected to the barrel cover member 300 through a stirring driving member 310, the stirring driving member 310 is connected to the barrel cover member 300, and the stirring assembly 400 comprises a stirring shaft 410, and the stirring driving member 310 is connected to the stirring shaft 410 through a transmission member 700.

[0057] In other words, the stirring driving member 310 is arranged above the barrel cover member 300, and drives the stirring shaft 410 located in the mixing cavity to rotate through the transmission member 700, thereby realizing stirring of the materials.

[0058] Reference Figure 2 , Figure 3 The barrel cover member 300 is connected to the rack 100, and is used to open or close the mixing cavity.

[0059] The first end 701 of the transmission member 700 extending into the mixing chamber is detachably connected to the stirring shaft 410 , and the second end 702 extending out of the mixing chamber is connected to the stirring driving member 310 .

[0060] The conventional stirring shaft 410 is directly mechanically connected to the transmission member 700, which makes it easy for materials to enter the gap between the transmission shaft and the sleeve member 600, resulting in obstructed rotation, large energy loss, and also causing bearing wear between the transmission shaft and the sleeve member 600.

[0061] In addition, the lubricating oil between the transmission shaft and the sleeve member 600 will directly drip into the mixing chamber, affecting the quality of the finished product.

[0062] In order to solve the above problems, the present application further provides a protective member 500 on the outside of the stirring shaft 410. The protective member 500 is located on the lower side of the sleeve member 600 and a rotation gap is formed between the protective member 500 and the sleeve member 600 to avoid interference between the protective member 500 and the sleeve member 600.

[0063] A protective surface 501 is formed on the outside of the protective member 500, which gradually shrinks away from the sleeve member 600. That is, the protective surface 501 is conical as a whole. The protective member 500 can protect the connection gap between the sleeve member 600 and the stirring shaft 410. The conical protective surface 501 is conducive to reducing material adhesion, preventing material from entering the connection gap, and avoiding interference with the rotation of the transmission member 700 and the stirring shaft 410 relative to the sleeve member 600.

[0064] Combine Figure 4 、 Figure 5 A transition portion 411 is formed at one end of the stirring shaft 410 connected to the protective member 500, a penetrating connecting channel 502 is formed in the protective member 500, and an inserting protrusion 412 is formed on the end surface of the transition portion 411, and the inserting protrusion 412 is inserted into the connecting channel 502.

[0065] Specifically, the plug-in protrusion 412 is an annular boss formed on the upper surface of the transition portion 411. The size of the plug-in protrusion 412 is adapted to the transition portion 411. The plug-in protrusion 412 is interference-connected to the bottom of the connecting channel 502 of the protective member 500 to avoid the formation of a gap between the plug-in protrusion 412 and the connecting channel 502.

[0066] In other embodiments, an upwardly extending connecting protrusion 413 is further formed on the end face of the transition portion 411, a threaded hole extending along the axial direction of the stirring shaft 410 is formed on the connecting protrusion 413, a connecting hole is formed on the transmission member 700 and is arranged to pass through the axial direction thereof, and the connecting end of the fastener 800 passes through the connecting hole from top to bottom and is connected to the threaded hole to realize a detachable connection between the transmission member 700 and the stirring shaft 410.

[0067] The fastener 800 is specifically a fastening screw structure, which is long enough to penetrate the transmission member 700 and the top end of the stirring shaft 410 to be fixed.

[0068] In some embodiments of the present application, the outer wall of the transition portion 411 is further formed with a matching surface tapering away from the protective member 500, and the matching surface and the protective surface 501 form a continuous tapered surface to make the transmission member 700 and the stirring shaft 410 more integrated.

[0069] The protective member 500 is further provided with an outer mounting recess 510 near one end of the sleeve member 600, the outer mounting recess 510 being an annular groove formed in the outer wall of the protective member 500, and the outer mounting recess 510 is provided with an outer sealing portion 511 for sealing the outer periphery of the rotating gap.

[0070] The outer sealing portion 511 can further reduce the entry of materials into the connecting gap, so that the connection environment between the sleeve member 600 and the transmission member 700 is better, and the lubricating oil between the sleeve member 600 and the transmission member 700 can be prevented from falling into the mixing cavity to ensure the quality of the finished product.

[0071] In some embodiments of the present application, the lower end of the transmission member 700 is inserted into the connecting channel 502, and the inner wall of the connecting channel 502 is further provided with an inner mounting recess, and the inner mounting recess is provided with an inner sealing portion 520 connected between the transmission member 700 and the inner mounting recess.

[0072] The inner sealing portion 520 is used to seal between the protective member 500 and the transmission member 700, to improve the stability of the connection between the protective member and the transmission member 700, and to prevent the lubricating oil between the sleeve member 600 and the transmission member 700 from overflowing.

[0073] Referring again to Figure 2 , the upper end of the sleeve member 600 is formed with a fixing flange 610, and the fixing flange 610 is dispersedly formed with a plurality of fixing holes, and the fastening screw passes through the corresponding fixing hole to fix the fixing flange 610 on the barrel cover member 300 to realize the connection and fixation of the sleeve member 600.

[0074] In some embodiments of the present application, the transmission member 700 is formed with a shaft shoulder portion 710, the size of the shaft shoulder portion 710 being greater than that of the rotating inner cavity, and the shaft shoulder portion 710 is correspondingly arranged at the upper end or the lower end of the sleeve member 600.

[0075] Taking the case that the shaft shoulder portion 710 is arranged near the upper end of the sleeve member 600, the transmission member 700 is connected into the rotating inner cavity of the sleeve member 600 from top to bottom.

[0076] When the shaft shoulder part 710 is arranged close to the lower end of the sleeve part 600, the transmission part 700 is connected into the rotating inner cavity of the sleeve part 600 from bottom to top, so as to realize the axial limiting of the transmission part 700.

[0077] At least one of the upper and lower ends of the sleeve part 600 is formed with a bearing chamber, and the first bearing part 630 is arranged in the bearing chamber.

[0078] Specifically, the bearing chambers are arranged at the upper and lower ends of the sleeve part 600, the sizes of the bearing chambers are greater than the size of the rotating inner cavity, the first bearing parts 630 are respectively arranged in the bearing chambers at the two ends of the sleeve part 600, the inner diameter of the first bearing part 630 is not greater than the inner diameter of the rotating inner cavity, and in the mounting state, the first bearing part 630 is in contact with the outer wall of the transmission part 700, thereby assisting the smooth rotation of the transmission part 700.

[0079] After the transmission part 700 is mounted, the axial position of the transmission part 700 is limited by the fixing seat 620.

[0080] The two ends of the sleeve part 600 are respectively detachably connected with the fixing seat 620, and the fixing seat 620 is sleeved outside the transmission part 700.

[0081] The circumferential side of the fixing seat 620 is also provided with penetrating fixing holes, and fastening structures such as fastening screws pass through the corresponding fixing holes to connect the fixing seat 620 to the two ends of the sleeve part 600.

[0082] The second bearing part 640 is arranged between the fixing seat 620 and the transmission part 700, and the second bearing part 640 is used to reduce the friction between the fixing seat 620 and the transmission part 700.

[0083] The abutting part 621 extending to the direction of the bearing chamber is formed on the fixing seat 620, the abutting part 621 is in abutment with the corresponding first bearing part 630, and the abutting part 621 is used to limit the first bearing part 630.

[0084] The specific mounting process of the stirring assembly 400 is as follows:

[0085] The sleeve part 600 is fixed on the barrel cover part 300 through the fixing flange 610.

[0086] The first bearing part 630 is arranged in the bearing chamber of the sleeve part 600.

[0087] The transmission part 700 passes through the rotating inner cavity and is limited by the shaft shoulder part 710.

[0088] The second bearing part 640 is pre-arranged on the fixing seat 620, is in contact with the outer wall of the transmission part 700, and connects the fixing seat 620 to the two ends of the sleeve part 600.

[0089] The abutting portion 621 on the fixing seat 620 is in contact with the first bearing member 630 to limit the first bearing member 630.

[0090] After the transmission member 700 is connected, the protective member 500 and the stirring shaft 410 are fixed on the transmission member 700 through the fastener 800 to realize the connection and fixation of the stirring shaft 410 and the transmission member 700.

[0091] In some embodiments of the present application, specifically, the stirring assembly 400 further comprises stirring blades 420 which are dispersedly arranged on the outer wall of the stirring shaft 410.

[0092] The stirring assembly 400 is rotatably connected to the barrel cover member 300 through the stirring driving member 310, and the stirring assembly 400 is arranged eccentrically to the barrel member 200.

[0093] In other words, the rotation center of the stirring shaft 410 does not coincide with the center of the barrel member 200, specifically, the stirring assembly 400 is arranged at an upper position in the barrel member 200 and is located upstream of the mixing cavity along the rotation direction of the barrel member 200.

[0094] When the barrel member 200 lifts the material upward from bottom to top, the material falls under the action of its own gravity after being further stirred by the stirring assembly 400, and thus the material is dispersed and mixed more uniformly through repeated stirring.

[0095] During work, the material in the mixing cavity is flipped upward to the corresponding stirring interval of the stirring assembly 400 along with the rotation of the barrel member 200, and is further mixed by the stirring blades 420.

[0098] Specifically, a hinged convex portion extending downward is formed on the connecting base 320, the hinged convex portion is hingedly connected to the rear side of the support stand 120 through a rotating shaft, so that the connecting base 320 is rotatably connected to the top of the support stand 120.

[0099] When the barrel cover 300 is opened, the connecting base 320 is flipped backward to open, so that the barrel cover 300 exposes the mixing cavity, facilitating the feeding of materials into the mixing cavity or the output of the mixed product.

[0100] In combination Figure 7 , Figure 9 and Figure 10 , the opening and closing of the barrel cover 300 is realized by the first driving member 322. Specifically, the first driving member 322 is formed on the support base 110, the fixed end of the first driving member 322 is hinged to the support base 110, and the telescopic end of the first driving member 322 is hinged to the support stand 120, for driving the opening and closing of the barrel cover 300.

[0106] The support base 110 is formed with a first photoelectric detection position 111 and a second photoelectric detection position 112. When the switch detection part 321 contacts the first photoelectric detection position 111, the barrel cover 300 is opened to the position. When the switch detection part 321 contacts the second photoelectric detection position 112, the barrel cover 300 is closed to the position.

[0107] The action of the first driving member 322 on the mixing machine is controlled by the control console, which includes a controller and an operation button. The operator triggers the operation button to control the action of the first driving member 322, and further controls the opening and closing of the barrel cover 300.

[0108] The first photoelectric detection position 111 and the second photoelectric detection position 112 are connected with the controller, the controller controls the switch of the first driving member 322, when the first photoelectric detection position 111 detects that the switch detection part 321 moves to the position, the first photoelectric detection position 111 sends the to-position signal to the controller, the controller controls the first driving member 322 to stop elongation, and the barrel cover member 300 is opened to the position.

[0109] When the second photoelectric detection position 112 detects that the switch detection part 321 moves to the position, the second photoelectric detection position 112 sends the to-position signal to the controller, the controller controls the first driving member 322 to stop contraction, and the barrel cover member 300 is closed to the position.

[0110] The first photoelectric detection position 111 and the second photoelectric detection position 112 provide photoelectric control for the switch of the barrel cover member 300, and the barrel cover limiting part provides mechanical limiting for the closing of the barrel cover member 300.
