Since the bottom diameter of the funnel-shaped feed hopper is small, when the staff pours a large amount of material into the feed hopper at one time, it is easy to cause the raw materials to accumulate at the bottom of the hopper, that is, it will cause the hopper to be blocked, thereby affecting the subsequent stirring efficiency of the material. For this reason, we propose a powder coating stirring device to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A powder coating stirring device includes a stirring box 1, a feeding hopper 2 is provided at the top of the stirring box 1, a discharge port 3 is provided at the bottom of the stirring box 1, a double-shaft motor 4 is provided inside the stirring box 1, and second rotating shafts 8 are symmetrically distributed at both ends of the double-shaft motor 4, and stirring blades 10 are evenly connected to the outer side of the second rotating shaft 8. The second rotating shaft 8 is a prior art and can drive two groups of first rotating shafts 5 to rotate synchronously. The specific working principle is not described in detail here. A linkage rod 14 is connected to the upper side of the second rotating shaft 8, and the linkage The outer side of the rod 14 is symmetrically connected with a sleeve rod 15, and an insertion rod 17 is inserted inside the sleeve rod 15. Since the linkage rod 14 is connected to one group of the second rotating shafts 8, and the sleeve rod 15 and the insertion rod 17 extend to the inside of the feed hopper 2, when the second rotating shaft 8 rotates, the linkage rod 14 can be driven to rotate at the same time, and the sleeve rod 15 and the insertion rod 17 connected to the outer side of the linkage rod 14 are stirred inside the feed hopper 2 to achieve unblocking of the feed hopper 2, and can effectively prevent the feed hopper 2 from being blocked during use.

[0023] Further, see Figure 2 It can be known that the two ends of the dual-axis motor 4 are symmetrically connected with the first rotating shaft 5, and the sides of the first rotating shaft 5 away from each other are respectively sleeved with bevel gear sets 7, and the bevel gear sets 7 are all sleeved at the top position of the second rotating shaft 8. Each group of bevel gear sets 7 is composed of two bevel gears, and the two bevel gears are respectively sleeved on the outside of the first rotating shaft 5 and the top of the second rotating shaft 8. Therefore, when the first rotating shaft 5 rotates, it can drive the two groups of second rotating shafts 8 to reverse rotation. Because the two groups of bevel gear sets 7 are symmetrically distributed, the directions of the two groups of second rotating shafts 8 can be opposite, so that the stirring directions of the two groups of stirring blades 10 are opposite, so as to achieve sufficient stirring of the raw materials.

[0024] Further, see Figure 1 and Figure 4 It can be known that the bottom end of the second rotating shaft 8 is movably sleeved with a support sleeve 12, and the outer side of the support sleeve 12 is connected to the inner wall of the mixing box 1 through a cross bar 13. Through the cooperation between the support sleeve 12 and the cross bar 13, the support of the bottom end of the second rotating shaft 8 can be achieved. Since the support sleeve 12 and the second rotating shaft 8 are movably connected, the normal rotation of the second rotating shaft 8 will not be affected, and the stability of the second rotating shaft 8 during rotation can be guaranteed.

[0025] Further, see Figure 1 and Figure 2It can be known that a support cover 6 is installed on the outside of the bevel gear set 7, and the top of the support cover 6 is set to an arc structure. The side of the support cover 6 is connected to the inner wall of the mixing box 1 through a support rod 9, and each bevel gear is connected to the inner wall of the support cover 6 through a bearing. When in use, through the setting of the support cover 6, while protecting the bevel gear set 7, the stability of the bevel gear set 7 during rotation can also be ensured. Since the top of the support cover 6 is set to an arc shape, it can prevent the accumulation of materials. Through the setting of the support rod 9, the support cover 6 can be supported and fixed.

[0026] Further, see Figure 2 It can be known that a protective cover is provided on the outside of the dual-axis motor 4, and the front and back sides of the protective cover are connected to the inner wall of the mixing box 1 through a connecting rod. The protective cover is arranged as a columnar structure. The protective cover arranged through the columnar structure can protect the dual-axis motor 4 while preventing the accumulation of materials.

[0027] Further, see Figure 2 and Figure 3 It can be known that the inner wall of the sleeve rod 15 is laterally connected with a spring 16, and the other end of the spring 16 is fixedly connected to the insertion rod 17, the end of the insertion rod 17 is connected with an impact bar 18, and the inner wall of the feed hopper 2 is equidistantly distributed with fixed bars 19. During the rotation of the linkage rod 14, the spring 16 connected to the inner side of the insertion rod 17 can provide a certain activity space for the impact bar 18. Therefore, when the linkage rod 14 rotates, the two groups of impact bars 18 can intermittently impact each group of fixed bars 19, so that the feed hopper 2 is subjected to force vibration, so that the material attached to its inner wall falls smoothly, so as to further prevent the feed hopper 2 from being blocked during use.

[0028] Further, see Figure 1 and Figure 4 It can be seen that rectangular grooves are respectively opened inside the stirring blade 10, and the inner walls of the rectangular grooves are equidistantly connected with reinforcing ribs 11. By opening the rectangular grooves, the movement obstruction of the material can be effectively reduced to achieve the protection of the stirring blade 10. Combined with the connection of multiple groups of reinforcing ribs 11, the overall structural strength of the stirring blade 10 can be effectively guaranteed, thereby effectively extending the service life of the stirring blade 10.

[0029] Working principle: When the utility model is in use, the staff can first start the work of the double-axis motor 4, so that it drives the two sets of first rotating shafts 5 to rotate simultaneously, and cooperates with the bevel gear set 7 sleeved on the outer side of the first rotating shaft 5 to realize the reversing rotation of the second rotating shaft 8. In addition, since the two sets of bevel gear sets 7 are symmetrically distributed, the rotation directions of the two sets of second rotating shafts 8 can be opposite. At this time, the staff can pour the raw materials to be mixed into the inside of the feed hopper 2, and then the materials can fall into the inside of the mixing box 1 due to gravity. With the two sets of stirring blades 10 set in opposite directions, the raw materials can be fully stirred. In addition, due to the top of the linkage rod 14 and one of the second rotating shafts 8 The sleeve rod 15 and the insertion rod 17 connected to the outside of the linkage rod 14 can be rotated inside the feed hopper 2 to realize the turning of the material, thereby effectively preventing the material from being blocked inside the feed hopper 2. In addition, when the insertion rod 17 rotates, it is combined with the spring 16 connected to its end to drive the impact bar 18 to intermittently impact each group of fixed bars 19, and transmit the impact force to the feed hopper 2. Since the feed hopper 2 is made of metal, it can generate resonance when subjected to force, thereby knocking off the material attached to its inner wall, thereby ensuring the falling speed of the material, thereby further preventing the material from being blocked inside the feed hopper 2. The above is the entire working principle of the utility model.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
