Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch processing equipment, and particularly relates to a drying device for masterbatch production. Background Technique

[0002] In the process of masterbatch production, most traditional drying devices use high-temperature baking. Although this method has high drying efficiency, if the baking time and temperature are not well controlled, it is easy to damage the raw materials, and the feeding and discharging of materials are not convenient.

[0003] A Chinese patent with the authorization announcement number CN210880404U discloses a drying device for masterbatch production, including a load-bearing base. The beneficial effects are as follows: The device is provided with an air-drying barrel and a drying fan, etc. When in use, the masterbatch is poured into the air-drying barrel from one side of the air-drying barrel, and the limiting rod is correspondingly inserted into the limiting groove, so that the cover plate is in contact with the air-drying barrel. The rotating motor and the drying fan are started. The rotating motor drives the air-drying barrel to rotate, and the drying fan blows air through the small holes on the inner wall of the air-drying barrel onto the masterbatch inside it to uniformly dry it. The water generated by drying is thrown out through the small holes, and the design of the guide plate can prevent water from entering the rotating groove. After a period of time, the servo motor can be started to drive the roller to rotate, so that the side plate is tilted, and the cover plate is removed to pour out the masterbatch in the air-drying barrel. This design makes the discharging of the masterbatch very convenient and can continuously and uniformly dry it.

[0004] As common knowledge, during the drying process of this utility model, the air-drying barrel should rotate in a horizontal state. If the air-drying barrel is in an inclined state, the materials inside it will accumulate on one side of the air-drying barrel, thus affecting the drying efficiency.

[0005] After drying a batch of materials and completing the discharging process of this utility model, it is necessary to first rotate the air-drying barrel to reset. If it is rotated and reset to the horizontal state, the materials need to be poured into the air-drying barrel through the opening on the right side of the air-drying barrel. The opening is provided on the right side of the air-drying barrel. Compared with the commonly used top-opening method in the prior art, the feeding is more inconvenient, and the amount of materials that can be stored in the air-drying barrel is also less. If it is rotated to the state where the opening on the right side of the air-drying barrel is inclined upward, although there will be no inconvenience during feeding, after the feeding is completed, the air-drying barrel still needs to be rotated again to keep it horizontal. Compared with directly rotating the air-drying barrel to the horizontal state, an additional procedure is added, resulting in lower working efficiency.

[0006] To sum up, no matter which operation method this utility model adopts, its feeding process is not very convenient and there is still a large room for improvement.

[0007] Therefore, the utility model proposes a technical solution to solve the problem of inconvenient feeding process described above. Summary of the Invention

[0008] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a drying device for masterbatch production, aiming to achieve the technical effect of quickly and conveniently pouring the next batch of materials into the air-drying barrel after drying a batch of materials and completing the feeding, so as to improve the working efficiency.

[0009] A drying device for masterbatch production includes a base, a side plate rotatably connected to the top end of the base, a top plate fixed to the top end of the side plate, an air-drying device installed on the top plate, a holding device installed on the side plate, and a rotating device installed on the top end of the base;

[0010] The holding device includes an air-drying barrel part for holding materials and a rotating part for driving the air-drying barrel part to rotate;

[0011] The air-drying barrel part is in a horizontal shape extending horizontally from left to right. The air-drying barrel part includes an annular filter screen, a cylindrical rotating block, a first cover body and a second cover body. The annular filter screen is located directly below the air-drying device. A connecting ring is fixed to the right end of the annular filter screen. A plug rod for inserting the connecting ring is fixed on the second cover body. The cylindrical rotating block is fixed to the left end of the annular filter screen and is rotatably connected to the side plate through a bearing. The left end of the cylindrical rotating block passes through the side plate and is provided with a sunk groove. A through groove leading to the inside of the annular filter screen is provided at the bottom of the sunk groove. The first cover body is inserted into the sunk groove in a mating connection manner;

[0012] The rotating part includes a first motor, a driving wheel and a driven wheel. The first motor is installed on the left side wall of the side plate. The driving wheel is fixedly installed on the output shaft of the first motor. The driven wheel is fixedly sleeved on the outer side wall of the cylindrical rotation and corresponds to the driving wheel. The driving wheel and the driven wheel are connected by a belt drive.

[0013] By adopting the above technical solution, when it is necessary to pour the first batch of materials into the air-drying barrel part, first drive the side plate to rotate through the rotating device. The side plate drives the cylindrical rotating block to rotate, and the cylindrical rotating block drives the annular filter screen to rotate, so that the air-drying barrel part presents an inclined state with the left side higher than the right side. Then, the first cover body is pulled out from the sunken groove, so as to open the through groove. The materials are poured into the sunken groove, and the materials will fall into the annular filter screen along the inclined through groove. Since the right end of the annular filter screen is blocked by the second cover body and the insertion rod, the materials will gradually accumulate in the annular filter screen. After that, the first cover body is re-closed and the air-drying barrel part is driven by the rotating device to rotate and reset to a horizontal state. At this time, the annular filter screen is just located directly below the air-drying device. Then, the air-drying device is started, and the first motor is started. The first motor drives the driving wheel to rotate. The driving wheel drives the driven wheel to rotate through the belt. The driven wheel drives the cylindrical rotating block to rotate. The cylindrical rotating block drives the annular filter screen to rotate. Thus, the materials in the annular filter screen are evenly air-dried. After the first batch of materials is air-dried, the side plate is driven to rotate through the rotating device, and the air-drying barrel part presents an inclined state with the left side higher than the right side again. Then, the insertion rod is pulled out from the connecting ring, so that the connecting ring and the right end of the annular filter screen are no longer blocked by the second cover body and the insertion rod. The air-dried materials in the annular filter screen are automatically poured out. After all the air-dried materials in the annular filter screen are poured out, the insertion rod is re-inserted into the connecting ring, so that the second cover body and the insertion rod block the right end of the connecting ring and the annular filter screen. Then, the first cover body is directly pulled out from the sunken groove. The second batch of materials is directly poured into the annular filter screen through the sunken groove and the through groove. By repeating the above operations, each batch of materials can be continuously air-dried. After the utility model dries a batch of materials and completes the blanking, the next batch of materials can be quickly and conveniently poured into the air-drying barrel, thereby improving the working efficiency.

[0014] Further setting of the utility model: The rotating device includes two rotating parts for driving the side plate to rotate and a driving part for driving the two rotating parts to start and stop simultaneously;

[0015] The driving part includes a housing, a rotating rod, a second motor and two driving gears. The housing is fixed to the left side of the top of the base. The rotating rod is rotatably connected to the housing through a bearing and extends horizontally back and forth. The two driving gears are both fixedly sleeved on the outside of the rotating rod. The second motor is installed on the outer side wall of the housing for driving the rotating rod to rotate;

[0016] Both of the two rotating parts are located on the right side of the driving part and are symmetrically arranged front and back. The rotating part includes a mounting block, a fixing block, a lead screw, a nut seat, a connecting rod and a guide rail. The mounting block and the fixing block are both fixed to the top of the base and are symmetrically arranged left and right. The guide rail is fixedly connected between the mounting block and the fixing block. The lead screw is rotatably connected between the mounting block and the fixing block through a bearing. One end of the lead screw passes through the mounting block and penetrates into the housing and is fixed with a driven gear meshing with the driving gear. The nut seat is sleeved outside the lead screw in a threaded connection manner and is sleeved outside the guide rail in a sliding connection manner. One end of the connecting rod is hinged to the top of the nut seat, and the other end of the connecting rod is hinged to the side plate. The side plate is rotatably connected between the two mounting blocks through a pin shaft.

[0017] By adopting the above technical solution, when it is necessary to drive the side plate to rotate through the rotating device, the second motor is started. The second motor drives the rotating rod to rotate. The rotating rod drives the two driving gears to rotate simultaneously. The two driving gears respectively drive the two driven gears to rotate simultaneously. The driven gear drives the lead screw fixedly connected thereto to rotate. The rotation of the lead screw drives the nut seat to form a trend of rotating and sliding along the lead screw at the same time. At the same time, since the nut seat is slidably sleeved on the guide rail, the guide rail plays a circumferential limiting role on the nut seat. Therefore, the rotation trend of the nut seat is offset, and the nut seat only slides left and right along the lead screw and the guide rail. The nut seat drives the connecting rod to move and rotate. The connecting rod drives the side plate to rotate between the two mounting blocks.

[0018] A further setting of the present utility model: The cross-sectional shapes of the sinking groove and the through groove are both circular. The inner wall of the sinking groove is provided with a first internal thread, and the outer wall of the first cover body is provided with a first external thread that is cooperatively connected with the first internal thread.

[0019] By adopting the above technical solution, the setting of the first internal thread and the first external thread improves the connection stability between the first cover body and the sinking groove.

[0020] A further setting of the present utility model: The inner wall of the connecting ring is provided with a second internal thread, the outer wall of the inserting rod is provided with a second external thread that is cooperatively connected with the second internal thread, and the left side of the inserting rod is flush with the connecting ring.

[0021] By adopting the above technical solution, the setting of the second internal thread and the second external thread improves the connection stability between the inserting rod and the connecting ring. And the left side of the inserting rod is flush with the connecting ring, which can prevent materials from entering the connecting ring.

[0022] A further setting of the present utility model: The first cover body is fixed with an extension rod for penetrating into the through groove. The other end of the extension rod is fixed with a plug for blocking the through groove, and the right side of the plug is flush with the cylindrical rotating block.

[0023] By adopting the above technical solution, when the first cover body is completely located in the trough, the right side of the plug is flush with the cylindrical rotating block, and the plug blocks the through slot, thereby preventing materials from entering the through slot.

[0024] A further configuration of the utility model is that handles are fixed on both the first cover body and the second cover body.

[0025] By adopting the above technical solution, the provision of the handle facilitates the disassembly and assembly of the first cover body and the second cover body.

[0026] Compared with the prior art, the beneficial effects of the utility model are:

[0027] A drying device for masterbatch production. After drying a batch of materials and unloading them, the utility model can quickly and conveniently pour the next batch of materials into an air drying barrel, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] This embodiment is an improvement on the problem that in a drying device for masterbatch production with the authorization announcement number CN210880404U, no matter which operation method is adopted, the feeding process is not very convenient. Therefore, in this embodiment, the drying device is not specifically described, and its specific structure can refer to the relevant description in the Chinese patent "A Drying Device for Masterbatch Production" with the authorization announcement number CN210880404U.

[0035] The holding device includes a drying barrel part for holding materials and a rotating part for driving the drying barrel part to rotate;

The right side of the plug 13 is flush with the cylindrical rotating block 5.

[0039] The rotating part includes a first motor 14, a driving wheel 15 and a driven wheel 16. The first motor 14 is installed on the left side wall of the side plate 2. The driving wheel 15 is fixedly installed on the output shaft of the first motor 14. The driven wheel 16 is fixedly sleeved on the outer side wall of the cylindrical rotation part and corresponds to the driving wheel 15. The driving wheel 15 and the driven wheel 16 are connected by belt drive.

[0040] The rotating device includes two rotating parts for driving the side plate 2 to rotate and a driving part for driving the two rotating parts to start and stop simultaneously.

[0041] The driving part includes a housing 17, a rotating rod 18, a second motor 19 and two driving gears 20. The housing 17 is fixed to the left side of the top of the base 1. The rotating rod 18 is rotatably connected to the inside of the housing 17 through a bearing and extends horizontally in the front and back directions. The two driving gears 20 are both fixedly sleeved outside the rotating rod 18. The second motor 19 is installed on the outer side wall of the housing 17 for driving the rotating rod 18 to rotate.

[0042] The two rotating parts are both located on the right side of the driving part and are symmetrically arranged in the front and back directions. The rotating part includes a mounting block 21, a fixing block 22, a lead screw 23, a nut seat 24, a connecting rod 25 and a guide rail 26. The mounting block 21 and the fixing block 22 are both fixed to the top of the base 1 and are symmetrically arranged left and right. The guide rail 26 is fixedly connected between the mounting block 21 and the fixing block 22. The lead screw 23 is rotatably connected between the mounting block 21 and the fixing block 22 through a bearing. One end of the lead screw 23 passes through the mounting block 21 and penetrates into the housing 17 and is fixed with a driven gear 27 that meshes with the driving gear 20. The nut seat 24 is sleeved outside the lead screw 23 in a threaded connection manner and is sleeved outside the guide rail 26 in a sliding connection manner. One end of the connecting rod 25 is hinged to the top of the nut seat 24, and the other end of the connecting rod 25 is hinged to the side plate 2. The side plate 2 is rotatably connected between the two mounting blocks 21 through a pin shaft.

[0043] Additionally, handles 28 are both fixed on the first cover body 6 and the second cover body 7. The setting of the handles 28 facilitates the disassembly and assembly of the first cover body 6 and the second cover body 7.

[0044] Working principle: When it is necessary to pour the first batch of materials into the air-drying barrel part, first start the second motor 19. The second motor 19 drives the rotating rod 18 to rotate. The rotating rod 18 drives the two driving gears 20 to rotate simultaneously. The two driving gears 20 respectively drive the two driven gears 27 to rotate simultaneously. The driven gear 27 drives the lead screw 23 fixedly connected thereto to rotate. The rotation of the lead screw 23 drives the nut seat 24 to form a tendency to slide to the right along the lead screw 23 while rotating. At the same time, since the nut seat 24 is slidably sleeved on the guide rail 26, the guide rail 26 plays a circumferential limiting role on the nut seat 24. Therefore, the rotation tendency of the nut seat 24 is offset, and the nut seat 24 only slides to the right along the lead screw 23 and the guide rail 26. The nut seat 24 drives the connecting rod 25 to move and rotate. The connecting rod 25 drives the side plate 2 to rotate downward between the two mounting blocks 21. The side plate 2 drives the cylindrical rotating block 5 to rotate, and the cylindrical rotating block 5 drives the annular filter screen 4 to rotate, so that the air-drying barrel part presents an inclined state with the left side high and the right side low. The second motor 19 can adopt a brake servo motor. At this time, through the self-locking effect between the lead screw 23 and the nut seat 24 and the self-locking of the second motor 19, the inclined side plate 2 can be stably supported. And the side plate 2, the connecting rod 25 and the base 1 are triangular, further improving the stability of the inclined side plate 2.

[0045] Then rotate the first cover 6 out of the sunk groove 10 until both the extension rod 12 and the plug 13 are pulled out of the cylindrical rotating block 5, thereby opening the through groove 11. Pour the materials into the sunk groove 10, and the materials will fall into the annular filter screen 4 along the inclined through groove 11. Since the right end of the annular filter screen 4 is blocked by the second cover 7 and the plug rod 9, the materials will gradually accumulate in the annular filter screen 4.

[0046] After that, re-cover the first cover 6 and reverse the rotation of the output shaft of the second motor 19, thereby driving the air-drying barrel part to rotate upward and reset to a horizontal state. At this time, the annular filter screen 4 is just located directly below the air-drying device.

[0047] Then start the air-drying device and start the first motor 14. The first motor 14 drives the driving wheel 15 to rotate. The driving wheel 15 drives the driven wheel 16 to rotate through the belt. The driven wheel 16 drives the cylindrical rotating block 5 to rotate. The cylindrical rotating block 5 drives the annular filter screen 4 to rotate. Thus, the materials in the annular filter screen 4 are evenly air-dried.

[0048] After the first batch of materials is air-dried, start the second motor 19 again to drive the side plate 2 to rotate downward, so that the air-drying barrel part presents an inclined state with the left side high and the right side low again. Then rotate the second cover 7, thereby driving the plug rod 9 to rotate out of the connecting ring 8, so that the connecting ring 8 and the right end of the annular filter screen 4 are no longer blocked by the second cover 7 and the plug rod 9. The air-dried materials in the annular filter screen 4 are automatically poured out.

[0049] After all the materials to be air-dried inside the annular filter screen 4 are emptied, re-insert the insertion rod 9 into the connecting ring 8, so that the second cover body 7 and the insertion rod 9 block the right end of the connecting ring 8 and the annular filter screen 4.

[0050] Then directly rotate the first cover body 6 out of the sinking groove 10. Pour the second batch of materials directly into the annular filter screen 4 through the sinking groove 10 and the through groove 11. Repeating the above operations can continuously air-dry each batch of materials.

[0051] After drying a batch of materials and completing the feeding in the utility model, the next batch of materials can be quickly and conveniently poured into the air-drying barrel, thereby improving the working efficiency.
