[0003] Among the existing technical solutions, the patent number is CN219044030U, and its name is a masterbatch drying device. During the masterbatch drying process, its drying efficiency is relatively low. For this reason, we need to solve the problem of drying efficiency and design a new technical solution.

[0008] By pulling out the plug on the feed pipe, adding the masterbatch to be dried, the masterbatch will enter the cavity inside the cylinder through the feed pipe, and then the plug is inserted into the inside of the feed pipe. Since the through hole opened on the outside of the cylinder is smaller than the size of the masterbatch, the masterbatch to be dried will not fall out of the cavity of the cylinder. The motor rotates to drive the connecting shaft fixedly connected to its output shaft. Since the connecting shaft is rotatably connected to the hole groove opened on one side of the support frame, the cylinder fixedly connected to the connecting shaft can be driven to start rotating synchronously with the output shaft of the motor.

Since the interior of the arc-shaped plate body is provided with a cavity, and the evenly distributed air outlet pipes fixedly connected to the lower side of the arc-shaped plate body and the air inlet pipe fixedly connected to the upper side of the arc-shaped plate body form a complete ventilation channel, the hot air flow is connected to the air inlet pipe at this time, and it will be evenly blown to the masterbatch to be dried that is constantly rolling in the cylinder body, further accelerating the drying effect. The air flow blown out of the hot air pipe also acts on the heat generated by the heating plate on the lower side of the cylinder body, so that its heat acts more effectively on the masterbatch, thereby improving the drying effect.

[0036] By pulling out the plug on the feed pipe 43, the masterbatch to be dried is added therein, and the masterbatch will enter the cavity inside the cylinder 41 through the feed pipe 43, and then the plug is inserted into the inner side of the feed pipe 43. Since the through hole provided on the outer side of the cylinder 41 is smaller than the size of the masterbatch, the masterbatch to be dried will not fall out of the cavity of the cylinder 41. The motor 5 is rotated to drive the connecting shaft fixedly connected to its output shaft. Since the connecting shaft is rotatably connected to the hole groove provided on one side of the support frame 3, the cylinder 41 fixedly connected to the connecting shaft can be driven to start to rotate synchronously with the output shaft of the motor 5.

[0037] Among them, the annular protrusion 44 is fixedly connected to one side of the cylinder 41. Since the outer side of the annular protrusion 44 is correspondingly provided with an annular fixing block 45 that is in contact with it, and the annular fixing block 45 is fixedly connected to one side of the support frame 3, the annular protrusion 44 can rotate steadily in the annular notch provided in the annular fixing block 45 as the cylinder 41 rotates without displacement.

[0039] Then, a heating plate 61 is arranged on the lower side of the cylinder 41 to match the outer shape thereof and form a certain gap. The design of this shape can make the heating plate 61 and the masterbatch to be dried in the cylinder 41 have a larger contact area, so the masterbatch in the cylinder 41 can be heated to the maximum extent. Then, a heating tube 62 is fixedly connected in the heating plate 61 to further increase the uniform heating effect of the heating plate 61, and effectively apply heat to the masterbatch in the cavity of the cylinder 41, so that the masterbatch can obtain uniform heat, and will not be damaged by uneven temperature, thereby improving the yield rate and the economic benefits.

The air outlet pipe 72, the air inlet pipe 73 and the cavity opened in the arc-shaped plate body 71 form a complete ventilation channel.

[0041] Then, an arc-shaped plate 71 matching the shape of the upper side of the cylinder 41 and provided with a certain gap is provided on the upper side of the cylinder 41. Since the interior of the arc-shaped plate 71 is provided with a cavity, and the evenly distributed air outlet pipes 72 fixedly connected to the lower side of the arc-shaped plate 71, and the air inlet pipe 73 fixedly connected to the upper side of the arc-shaped plate 71 form a complete ventilation channel, the hot air flow is connected to the air inlet pipe 73 at this time, and it will be evenly blown to the masterbatch to be dried that is constantly rolling in the cylinder 41, further accelerating the drying effect.

The length of the square slot provided on one side of the support frame 3 is greater than the diameter length of the end cover plate 82. The end cover plate 82 can move up and down in the direction slot. One side of the end cover plate 82 is sealed and abutted with one side of the annular fixing block 45. The lower side of the end cover plate 82 is abutted with an arc-shaped positioning plate 83.

The lower side of the arc-shaped positioning plate 83 is fixedly connected to the upper side of the support plate 2 through the connecting block.

[0043] The other end of the cylinder 41 is provided with a through hole. At this time, the end cover plate 82 in the cover plate assembly 8 can be moved by the electric telescopic rod 81 to extend so that the end cover plate 82 can be lowered to the inner wall of the arc-shaped positioning plate 83 and sealed and abutted against the annular fixing block 45, thereby sealing the masterbatch inside the cylinder 41 and preventing it from leaking out.

[0044] Furthermore, a discharge assembly 9 is provided on one side of the cover plate assembly 8, and the discharge assembly 9 includes a discharge trough 91 and a discharge pipe 92.

[0047] Finally, when the masterbatch to be dried is dried, the motor in the motor 5 is turned off, and the electric telescopic rod 81 is retracted to make the end cover plate 82 move upward along the matching square groove opened in the support frame 3, so that the end cover plate 82 and the annular fixing block 45 are completely dislocated and separated. At this time, the end cover plate 82 is attached to the upper side of the annular fixing block 45. At this time, the pneumatic hydraulic rod 101 begins to extend. Under the cooperation of the hydraulic rod 101, the spherical part 102 and the limiting boss 103, the support plate 2 and the base 1 are further rotated upward with the connecting axis of the rotating shaft 11 as the axis, so that the cylinder 41 is in an inclined state, and the dried masterbatch in the cylinder 41 will smoothly move to the discharge trough 91, wherein the discharge trough 91 is also not designed to be inclined, and finally it will be smoothly collected through the valve control on the discharge pipe 92 or enter the next processing step;

[0048] Furthermore, the lower side of the base 1 is fixedly connected with uniformly distributed universal wheels 12 .

[0049] The specific usage and function of this embodiment are as follows:

[0050] When in use, firstly, the masterbatch drying device is powered on and turned on, and the masterbatch to be dried is added therein by pulling out the plug on the feed pipe 43. The masterbatch will enter the cavity inside the cylinder 41 through the feed pipe 43, and then the plug is inserted into the inner side of the feed pipe 43. Since the through hole provided on the outer side of the cylinder 41 is smaller than the size of the masterbatch, the masterbatch to be dried will not fall out of the cavity of the cylinder 41. The motor 5 is rotated to drive the connecting shaft fixedly connected to its output shaft. Since the connecting shaft is rotatably connected to the hole groove provided on one side of the support frame 3, the cylinder 41 fixedly connected to the connecting shaft can be driven to start to rotate synchronously with the output shaft of the motor 5.

[0051] The other end of the cylinder 41 is provided with a through hole. At this time, the end cover plate 82 in the cover plate assembly 8 can be moved by the electric telescopic rod 81 to extend so that the end cover plate 82 can be lowered to the inner wall of the arc-shaped positioning plate 83 and sealed and abutted against the annular fixing block 45, thereby sealing the masterbatch inside the cylinder 41 and preventing it from leaking out.

[0052] Among them, the annular protrusion 44 is fixedly connected to one side of the cylinder 41. Since the outer side of the annular protrusion 44 is correspondingly provided with an annular fixing block 45 that is in contact with it, and the annular fixing block 45 is fixedly connected to one side of the support frame 3, the annular protrusion 44 can rotate steadily in the annular notch provided in the annular fixing block 45 as the cylinder 41 rotates without displacement. At this time, the spiral leaves 42 that are evenly distributed and fixedly connected to the inner wall of the cylinder 41 can make the masterbatch to be dried tumble during the rotation of the cylinder 41, so that each masterbatch to be dried can obtain more opportunities to fully contact with the outside air to the greatest extent, and quickly evaporate the moisture in the masterbatch, thereby achieving the beneficial effects of accelerating the drying speed of the masterbatch and improving the drying effect obtained;

[0053] Then, a heating plate 61 is arranged on the lower side of the cylinder 41 to match the outer shape thereof and form a certain gap. The design of this shape can make the heating plate 61 and the masterbatch to be dried in the cylinder 41 have a larger contact area, so the masterbatch in the cylinder 41 can be heated to the maximum extent. Then, a heating tube 62 is fixedly connected in the heating plate 61 to further increase the uniform heating effect of the heating plate 61, and effectively apply heat to the masterbatch in the cavity of the cylinder 41, so that the masterbatch can obtain uniform heat, and will not be damaged by uneven temperature, thereby improving the yield rate and the economic benefits.

[0054] Then, an arc-shaped plate 71 matching the shape of the upper side of the cylinder 41 and provided with a certain gap is provided on the upper side of the cylinder 41. Since the interior of the arc-shaped plate 71 is provided with a cavity, and the evenly distributed air outlet pipes 72 fixedly connected to the lower side of the arc-shaped plate 71, and the air inlet pipe 73 fixedly connected to the upper side of the arc-shaped plate 71 form a complete ventilation channel, the hot air flow is connected to the air inlet pipe 73 at this time, and it will be evenly blown to the masterbatch to be dried that is constantly rolling in the cylinder 41, further accelerating the drying effect. The airflow blown out of the hot air pipe also acts on the heat generated by the heating plate 61 on the lower side of the cylinder 41, so that its heat acts more effectively on the masterbatch, thereby improving the drying effect.

[0055] Finally, when the masterbatch to be dried is dried, the motor in the motor 5 is turned off, and the electric telescopic rod 81 is retracted to make the end cover plate 82 move upward along the matching square groove opened in the support frame 3, so that the end cover plate 82 and the annular fixing block 45 are completely dislocated and separated. At this time, the end cover plate 82 is attached to the upper side of the annular fixing block 45. At this time, the pneumatic hydraulic rod 101 begins to extend. Under the cooperation of the hydraulic rod 101, the spherical member 102 and the limiting boss 103, the support plate 2 and the base 1 are further rotated upward through the connecting axis of the rotating shaft 11 as the axis, so that the cylinder 41 is in an inclined state, and the dried masterbatch in the cylinder 41 will smoothly move to the discharge trough 91, wherein the discharge trough 91 is also not tilted. Finally, it will be smoothly collected or enter the next processing step through the valve control on the discharge pipe 92. After the dried masterbatch is completely dumped, the above operation can be reversed to carry out the next round of drying process.
