Description

Technical Field

[0001] This utility model belongs to the field of plastic powder production technology, specifically relating to a mixing machine for sample making. Background Technology

[0002] Powder coating is a thermosetting powder coating used for electrostatic spraying. Before production based on demand, manufacturers will create samples to avoid resource waste during large-scale production. After the sample passes various performance tests and is approved by the customer, formal production can begin. Sampling includes a mixing process, during which operators manually or with a mixer thoroughly mix the weighed materials.

[0003] The double cone mixer is a widely used type of mixer. The double cone mixer used for prototyping is smaller and has a simpler mechanism compared to the one used in production. It typically includes a support frame, a rotating shaft mounted on and rotatably connected to the support frame, a hopper fixed to the rotating shaft, and a motor that controls the rotation of a fixed rod. The motor controls the hopper's tumbling, ensuring uniform mixing of the materials within. While the prototyping double cone mixer is simple and easy to use, it becomes unusable in the event of a motor failure, hindering the mixing process. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a hybrid machine that can switch between manual and electric operation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sample mixing machine, comprising a support, a material bucket, and a motor. There are two supports, and the material bucket is disposed between the two supports. A rotating shaft one and a rotating shaft two are fixed to the outer wall of the material bucket. The two supports are respectively provided with a through hole one for rotating shaft one and a through hole two for rotating shaft two to pass through. The machine also includes a fixed frame separately disposed from the supports and a limiting member restricting the movement of the fixed frame. The motor is disposed on the fixed frame and includes a mating shaft. The end of rotating shaft one away from the material bucket is connected to the mating shaft via a perforated coupling. The perforated coupling includes two fixing parts respectively connected to the mating shaft and rotating shaft one. The end of rotating shaft two away from the material bucket is provided with a square connecting end, and an operating handle is sleeved on the connecting end. The operating handle includes a connecting groove whose shape is complementary to that of the connecting end.

[0006] With the above solution, the operating handle and the connecting end are set separately during daily use. The motor drives the material barrel to tumble through the rotating shaft. When the motor fails, the restriction of the limiting parts is released and the fixed frame is moved away from the support, so that the two fixed parts of the plum blossom coupling are separated. The connecting groove of the operating handle is then fitted onto the connecting end, and the material barrel can be manually rotated by the operating handle. This allows the motor maintenance and mixing process to be carried out simultaneously, preventing the material feeding process from being affected by the motor failure.

[0007] As a further feature of this utility model, it also includes a base, the bracket is fixed to the base, the base is provided with a guide rod fixedly connected to the base and a screw rod rotatably connected to the base, the guide rod and the screw rod both extend toward the bracket, the fixed frame is provided with a guide hole for the guide rod to pass through and a threaded hole for the screw rod to pass through, the screw rod is threadedly engaged with the threaded hole, the end of the screw rod away from the bracket passes through the base, and the end of the screw rod away from the bracket is provided with an operating part.

[0008] The above scheme ensures that the mating shaft, rotating shaft one, and rotating shaft two are always coaxially aligned, facilitating the separation and engagement of the plum blossom coupling. Through the engagement of the guide rod and guide hole, and the engagement of the screw rod and threaded hole, the motor can perform linear reciprocating motion, facilitating the insertion and separation of the two fixed parts.

[0009] As a further feature of this utility model, it also includes a U-shaped plug-in, and the bracket that cooperates with the second rotating shaft is provided with two insertion holes. The symmetrical plane of the two insertion holes passes through the axis of the second through hole. The two ends of the plug-in are inserted into the two insertion holes. The operating handle is L-shaped and is provided with a sleeve end. The connecting groove is located on the sleeve end.

[0010] Using the above solution, after the motor repair is completed, the operating handle and the bracket are kept relatively fixed by the plug, which can prevent the rotating shaft from rotating when the two fixed parts of the plum blossom coupling are connected, and facilitate the reconnection of the plum blossom coupling.

[0011] As a further feature of this utility model, one of the outer walls of the connecting end is provided with a first mark, the bracket is provided with a second mark, and the sleeve end is provided with a third mark. The second mark is located on the side of the opening of the second through hole, and the second mark coincides with the symmetrical plane of the two insertion holes.

[0012] Using the above scheme, when Mark 1, Mark 2, and Mark 3 are aligned simultaneously, the two fixing parts are in a convenient docking position, and the operating handle is located between the two sockets. When the operating handle is fitted onto the connecting end, first align Mark 1 with Mark 2, then align Mark 3 with Mark 2, place the operating handle between the two sockets, and fit it onto the connecting end. After the motor repair is completed, the operating handle can be fixed between the two sockets by the cooperation of the plug and the socket. At this time, the two fixing parts are in a convenient docking position, and then the screw can be turned to dock the two fixing parts.

[0013] As a further feature of this utility model, the limiting member includes a clamping seat disposed on the base, the clamping seat having a clamping hole for the screw to pass through, the inner wall of the clamping hole having an opening extending to the outer wall of the clamping seat, and clamping holes disposed opposite to each other on the two side walls opposite to the opening, a clamping rod passing through the clamping hole, the two ends of the clamping rod having a knob and an external thread respectively, and an internal thread cooperating with the external thread in the clamping hole away from the knob.

[0014] Using the above solution, when the screw does not need to be rotated, by rotating the knob, the side wall where the first clamping hole is located is brought closer to the side wall where the second clamping hole is located, so that the clamping hole and the outer wall of the screw are interference-fitted, preventing the screw from affecting the motor's drive of the second rotating shaft due to its own rotation.

[0015] As a further feature of this invention, there are two guide rods, which are evenly distributed on both sides of the screw.

[0016] By adopting the above scheme, the motor can move stably along the axis of the screw.

[0017] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Specific embodiments of this utility model are shown in the accompanying drawings.

[0025] A sample mixing machine includes a base 1, on which a bracket 2 is fixedly connected and a fixed frame 3 is slidably connected.

[0026] There are two supports 2, and a material bucket 4 is provided between the two supports 2. The outer wall of the material bucket 4 is fixed with a rotating shaft 1 41 and a rotating shaft 2 42. The two supports 2 are respectively provided with a through hole 1 21 for rotating shaft 1 41 to pass through and a through hole 22 for rotating shaft 2 42 to pass through. A motor 5 is provided on the fixed frame 3. The motor 5 includes a mating shaft 51. The mating shaft 51, rotating shaft 1 41 and rotating shaft 2 42 are always coaxially arranged. The end of rotating shaft 1 41 away from the material bucket 4 is connected to the mating shaft 51 through a plum blossom coupling. The plum blossom coupling includes two fixing parts a respectively connected to the mating shaft 51 and rotating shaft 1 41. The end of rotating shaft 2 42 away from the material bucket 4 is provided with a square connecting end 421. An operating handle 6 is sleeved on the connecting end 421. The operating handle 6 is L-shaped and has a sleeve end 61. The sleeve end 61 has a connecting groove 62 that is complementary in shape to the connecting end 421.

[0027] The base 1 is provided with a guide rod 71 fixedly connected to the base 1 and a screw 72 rotatably connected to the base 1. Both the guide rod 71 and the screw 72 extend towards the support 2. The fixed frame 3 is provided with a guide hole 31 for the guide rod 71 to pass through and a threaded hole 32 for the screw 72 to pass through. The screw 72 is threadedly engaged with the threaded hole 32. The end of the screw 72 away from the support 2 passes through the base 1. The end of the screw 72 away from the support 2 is provided with an operating part 73.

[0028] In daily use, the operating handle 6 and the connecting end 421 are set separately. The motor 5 drives the material bucket 4 to tumble through the cooperating shaft 51. When the motor 5 fails, the fixed frame 3 can be moved away from the bracket 2 by the cooperation of the guide rod 71 and the guide hole 31, and the screw 72 and the threaded hole 32, so that the two fixed parts a are separated. The connecting groove 62 of the operating handle 6 is fitted onto the connecting end 421, and the material bucket 4 can be manually rotated by the operating handle 6. This allows the maintenance of the motor 5 and the mixing process to be carried out at the same time, preventing the material feeding process from being affected by the failure of the motor 5.

[0029] The bracket 2, which mates with the rotating shaft 42, has two insertion holes 23. The symmetrical planes of the two insertion holes 23 pass through the axis of the through hole 22. Inserts 8 are inserted into the insertion holes 23. The inserts 8 are U-shaped and inserted into the two insertion holes 23 at both ends. After the motor 5 is repaired, the operating handle 6 is fixed to the bracket 2 by the inserts 8. This prevents the rotating shaft 41 from rotating when the two fixed parts a are connected, and facilitates the reconnection of the plum blossom coupling.

[0030] One outer wall of the connecting end 421 is marked with a first mark 422, the bracket 2 is marked with a second mark 24, and the sleeve end 61 is marked with a third mark 63. The second mark 24 is located on the side of the opening of the second through hole 22, and the second mark 24 coincides with the symmetrical plane of the two insertion holes 23. When the first mark 422, the second mark 24, and the third mark 63 are aligned at the same time, the two fixing parts a are in a convenient docking position, and the operating handle 6 is located between the two insertion holes 23. When the operating handle 6 is sleeved on the connecting end 421, first align the first mark 422 with the second mark 24, and then align the third mark 63 with the second mark 24, so that the operating handle 6 is placed between the two insertion holes 23 and sleeved on the connecting end 421. After the motor 5 is repaired, the operating handle 6 can be fixed between the two insertion holes 23 by the cooperation of the plug 8 and the insertion holes 23. At this time, the two fixing parts a are in a convenient docking position. Then, by rotating the screw 72, the two fixing parts a can be docked.

[0031] The base 1 is equipped with a clamping seat 9, which has a clamping hole 91 for the screw 72 to pass through. The inner wall of the clamping hole 91 has an opening 92 extending to the outer wall of the clamping seat 9. On opposite sides of the opening 92, clamping holes 93 are provided. A clamping rod 10 passes through the clamping hole 93. Both ends of the clamping rod 10 are respectively equipped with a knob 101 and an external thread. The clamping hole 93 furthest from the knob 101 has an internal thread that mates with the external thread. When the screw 72 does not need to be rotated, rotating the knob 101 moves the side wall of clamping hole 93 one closer to the side wall of clamping hole 93 two, thus achieving an interference fit between the clamping hole 91 and the outer wall of the screw 72. This prevents the screw 72 from rotating on its own and affecting the motor 5's drive of the rotating shaft 42.

[0032] There are two guide rods 71, which are evenly distributed on both sides of the screw 72. This allows the motor 5 to move stably along the axis of the screw 72.

[0033] This utility model is not limited to the specific embodiments described above. Those skilled in the art can implement this utility model using other specific embodiments based on the content disclosed in this utility model. Any simple changes or modifications made to the design structure and concept of this utility model will fall within the protection scope of this utility model.
