DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0028] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0029] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown in the figure, in the embodiment of the utility model, a stirring paddle material accumulation blowing structure suitable for a wet machine comprises a material cylinder 1, a stirring paddle 2 is arranged at the bottom of the material cylinder 1, a cylinder cover 3 is arranged at the upper opening of the material cylinder 1, a quick-release joint 31 is arranged at the top of the cylinder cover 3, and a blowing assembly is connected to the quick-release joint 31.

[0031] The purge assembly includes a purge pipe seat 41, a purge pipe 42, and a locking assembly located between the purge pipe 42 and the purge pipe seat 41. The purge pipe seat 41 is connected to the quick-release connector 31 to form a sealing fit. The purge pipe 42 is inserted into the purge pipe seat 41 and forms a fit therewith.

[0032] The upper end of the purge pipe 42 is an air inlet and is connected to an air inlet pipe 43. The lower end of the purge pipe 42 is an air outlet and extends into the interior of the material cylinder 1. The purge pipe 42 can move relative to the purge pipe seat 41 and has a first purge position with the air outlet close to the stirring paddle 2 and a first mixing position with the air outlet away from the stirring paddle 2.

[0033] With this arrangement, when materials need to be mixed or the lid is opened and in a non-discharging state, the purge pipe is pulled up to the first mixing position and locked to avoid interfering with other structures in the cylinder. When discharging is required, the purge pipe is moved down to the first purge position close to the agitator paddle and locked. Ventilation and purge through the air intake pipe can reduce the adhesion of materials to the agitator paddle, thereby reducing material waste.

[0034] The outer periphery of the upper end of the purge pipe seat 41 has an external thread section, and the locking assembly includes a locking nut 51, and the locking nut 51 includes a tightening portion 511 and a threaded connection portion 512 from top to bottom. The inner periphery of the threaded connection portion 512 forms a threaded fit with the outer periphery of the upper end of the purge pipe seat 41, and a first sealing member 52 is provided between the inner periphery of the tightening portion 511, the inner periphery of the upper end of the purge pipe seat 41, and the outer periphery of the purge pipe 42.

[0035] The outer periphery of the upper end of the first sealing member 52 has a first outer conical surface 521 , and the inner periphery of the abutting portion 511 is correspondingly provided with a first inner conical surface 5111 that matches the shape of the first outer conical surface 521 and forms an abutting fit.

[0036] With this arrangement, when the position of the purge pipe needs to be locked, the locking nut is rotated downward. During the downward movement of the locking nut, the first inner conical surface is pressed against the first outer conical surface of the first sealing member, so that the purge pipe, the purge pipe seat, and the first sealing member are pressed against each other to form a lock. When the position of the purge pipe needs to be adjusted, the locking nut is rotated upward to complete the unlocking, which is not only convenient for adjustment but also stable for locking. In this embodiment, the first sealing member is specifically a non-standard sealing ring.

[0037] The upper end of the purge pipe seat 41 is provided with a second inner conical surface 4111 on its inner periphery, and the lower end of the first sealing member 52 is correspondingly provided with a second outer conical surface 522 which is adapted in shape to the second inner conical surface 4111 and forms a tight fit.

[0038] With this arrangement, when the locking nut is moved downward for locking, the second outer conical surface abuts against the second inner conical surface, further improving the locking stability of the locking structure.

[0039] The purge pipe 42 includes a first pipe portion 421, a second pipe portion 422 and a third pipe portion 423 which are connected in sequence from top to bottom. The second pipe portion 422 is located in the purge pipe seat 41 and forms a movable fit therewith. The third pipe portion 423 is located in the material cylinder 1 and its outer diameter is smaller than that of the second pipe portion 422. The bottom of the third pipe portion 423 is bent toward the direction of the feeding port 11. The side wall of the material cylinder 1 has a feeding port 11. When the purge pipe 42 is located in the first purge position, the air outlet is located corresponding to the feeding port 11.

[0040] This arrangement is helpful to further disperse the material and optimize the effect of preventing the material from sticking to the stirring paddle.

[0041] The outer diameter of the second tube portion 422 is smaller than that of the first tube portion 421 and a limiting step 4211 is formed therebetween. When the purge tube 42 is located at the first purge position, the limiting step 4211 is located above the purge tube seat 41 or against the upper end of the purge tube seat 41 .

[0042] Through this arrangement, the purge pipe can be prevented from extending excessively into the material cylinder and affecting the operation of the stirring paddle. In this embodiment, when the purge pipe is located in the first purge position, the limiting step abuts against the upper end of the purge pipe seat, thereby improving the stability of the connection between the purge pipe and the purge pipe seat during purge.

[0043] The outer wall of the second tube portion 422 is provided with scales.

[0044] This setting is helpful to confirm the position of the sweep pipe in the material cylinder.

[0045] The purge pipe seat 41 includes an upper connection seat 411 that cooperates with the locking assembly, and a lower connection seat 413 that is inserted into the quick connector 31 and forms a sealing fit therewith. An abutment convex ring 412 extends outward from the connection between the upper connection seat 411 and the lower connection seat 413, and the lower end ring surface of the abutment convex ring 412 abuts against the upper end surface of the quick connector 31.

[0046] Through this arrangement, the abutting convex ring improves the stability of the connection between the purge and blow pipe seat and the quick-release connector, and at the same time, a detachable fixed connection between the two can be achieved through a clamp.

[0047] A first sealing ring 44 is provided between the outer periphery of the lower seat 413 and the inner periphery of the quick-release connector 31 , and a second sealing ring 45 is provided between the inner periphery of the lower seat 413 and the outer periphery of the purge pipe 42 .

[0048] Through this arrangement, the first sealing ring and the second sealing ring improve the sealing performance between the purge pipe, the purge pipe seat and the quick-release connector.

[0049] The air intake pipe 43 is provided with a one-way valve 431 .

[0050] Controlling the air intake pipe by a one-way valve can prevent leakage of materials in the material cylinder, wherein the specific control method of the one-way valve is prior art and will not be described in detail here.

[0051] The air inlet at the upper end of the purge pipe 42 is connected to a quick-twist elbow 424 and is connected to the air inlet pipeline 43 through the quick-twist elbow 424 .

[0052] This arrangement improves the convenience of disassembly and assembly of the air intake duct.

[0053] There are 7 evenly arranged at the bottom of the purge pipe 42. The hole is used as an air outlet to blow away the material accumulated on the stirring paddle.

[0054] The top of the cylinder cover 11 is an inclined surface, and the quick-release connector 31, the purge pipe seat 41, and the purge pipe 42 are all inclined, and the inclination between the vertical direction is set to 3-7°, preferably 5°. The third tube portion 423 of the purge pipe 42 includes a first fold portion 4231 and a second fold portion 4232. The first fold portion 4231 prevents the purge pipe from colliding with the mounting structure of the stirring paddle 2. The second fold portion 4232 is parallel to the bottom surface of the cylinder 1, and the air outlet is located on the second fold portion 4232, thereby further improving the purge effect and preventing the material from sticking to the stirring paddle.

[0055] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
