Description

Technical Field

[0001] The present invention relates to the technical field of masterbatch drying, and specifically relates to a masterbatch drying system. Background Art

[0002] Color masterbatch is a kind of masterbatch, which is a plastic colorant formed by well-dispersing a high proportion of pigments or additives and thermoplastic resins. When traditional color masterbatch is produced and manufactured, since there is a certain amount of moisture inside the raw materials, when the moisture content is relatively high, the color masterbatch is prone to adhesion, which is not conducive to transportation and storage, and easily affects the use effect and service life of the color masterbatch. Therefore, it is necessary to dry the color masterbatch through a drying device.

[0003] An existing masterbatch drying device, such as a color masterbatch dryer with the publication number of CN203888066U, includes a drying pipe and an air supply pump. The drying pipe includes a feed inlet and a discharge outlet. A hopper for placing the color masterbatch is provided at the feed inlet. The drying pipe includes an inner wall and an outer wall, and a cavity is provided between the inner wall and the outer wall. A plurality of air outlet holes are provided on the inner wall and are arranged along the direction from the feed inlet to the discharge outlet. The air outlet holes communicate with the cavity, and an air supply pipe is provided between the air supply pump and the cavity.

[0004] Although the above patent can dehydrate and dry the color masterbatch, the color masterbatch only realizes the drying effect by automatically falling by gravity. Since the moisture content of the color masterbatch is relatively high when it enters initially, some color masterbatches will stick together and cannot be dispersed, thus affecting the drying effect of the color masterbatch. Even if the adhered color masterbatches can be completely dried, since multiple color masterbatches are adhered and fixed after drying and cannot be separated, the production quality of the color masterbatch is affected. Therefore, in view of the above problems, a masterbatch drying system is designed to better meet the actual use requirements. Summary of the Invention

[0005] The purpose of the present invention is to provide a masterbatch drying system to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A masterbatch drying system includes a drying box and a motor. The motor is fixed to the side of the drying box. The output end of the motor is fixed with an elliptical wheel. The elliptical wheel is arranged inside the drying box. A material shaking mechanism is installed inside the drying box. The material shaking mechanism includes a shaking plate, a feeding port, a cylinder, a vertical rod, a circular plate, a spring and a fixed rod. There are two shaking plates arranged inside the drying box, and the two shaking plates are equally angularly provided with feeding ports, and the feeding ports on the upper shaking plate and the feeding ports on the lower shaking plate are staggeredly distributed. A material cleaning mechanism is arranged inside the feeding port. A material distributing mechanism is installed on the shaking plate. The shaking plate is equally angularly fixed with cylinders. The shaking plate is slidably connected to the vertical rod fixed inside the drying box. A circular plate is fixed on the vertical rod. The circular plate is slidably connected inside the cylinder. A spring is fixed between the circular plate and the shaking plate. A fixed rod is fixed on the shaking plate. The fixed rod is slidably connected to the elliptical wheel.

[0007] Preferably, a feed pipe is arranged at the upper end of the drying box, and the feed pipe is connected to a hopper. An exhaust hole is installed at the upper end of the drying box, and a discharge port is installed at the lower end of the drying box. A air supply mechanism is fixed inside the drying box. Through the above structure, the entry and exit of materials can be realized, and through the exhaust hole, the gas can be conveniently discharged, providing a basic guarantee for the normal operation of the device.

[0008] Preferably, the material cleaning mechanism includes a circular ring, a connecting rod, a fixing frame, a guiding rod and a movable block. The circular ring is fixed on the vertical rod, and the circular ring and the shaking plate are in one-to-one correspondence. The circular ring is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the fixing frame. The fixing frame and the feeding port are in one-to-one correspondence. When the shaking plate is stressed and moves, with the transmission of the connecting rod, a basic acting force can be provided for the movement of the fixing frame.

[0009] Preferably, the fixing frame is slidably connected to the guiding rod, and the guiding rod is fixed on the shaking plate. When the fixing frame moves, with the sliding guiding effect between the fixing frame and the guiding rod, the stability of the movement of the fixing frame can be ensured.

[0010] Preferably, a movable block is fixed on the fixing frame, and the movable block is slidably connected to the feeding port. The two ends of the movable block are gradually narrowed in width. When the fixing frame moves, the movable block is synchronously driven to move. Through the action of the movable block, the feeding port can be cleaned to prevent the feeding port from being blocked by materials and affecting the normal operation of the device.

[0011] Preferably, the material distribution mechanism includes a rotating shaft, a baffle plate, a loosening rod, a material distribution plate, a striking plate, a round rod, a spiral groove, and a sliding rod. The rotating shaft is connected to the upper vibrating plate through a bearing, and is slidably connected to the lower vibrating plate. A baffle plate is fixed on the rotating shaft, and the baffle plate cooperates with the feed pipe to achieve a sealing effect. When the upper vibrating plate moves, it can provide a basic acting force for the movement of the rotating shaft. Through the movement of the rotating shaft, the baffle plate can be driven to move synchronously, so as to realize the opening and closing of the feed pipe, and then realize intermittent feeding, and then ensure the drying effect of the material.

[0012] Preferably, a loosening rod is fixed on the baffle plate, and the loosening rod is arranged in the hopper. Through the rotation of the loosening rod, the material can be loosened, so as to avoid the adhesion of the material and affect the normal feeding function, and ensure the normal operation of the device.

[0013] Preferably, a material distribution plate is fixed on the rotating shaft, and strip-shaped holes are evenly formed in the material distribution plate. A striking plate is also fixed on the rotating shaft. When the material falls onto the material distribution plate, through the rotational centrifugal action of the material distribution plate, the material can be dispersed. And when the material splashes under the action of the vibrating plate, the material can be struck by the striking plate, so as to effectively avoid the adhesion of the material and ensure the drying effect of the material.

[0014] Preferably, a round rod is fixed at the lower end of the rotating shaft, and a spiral groove is formed in the round rod. The spiral groove is slidably connected to the sliding rod, and the sliding rod is fixed on the lower vibrating plate. When the lower vibrating plate moves downward, the sliding rod is driven to move synchronously. With the sliding action between the sliding rod and the spiral groove, it can provide a basic acting force for the rotation of the round rod, the striking plate, and the loosening rod, and ensure the normal operation of the device.

[0015] Preferably, the air supply mechanism includes an air inlet pipe, a wind guiding ring, and a spray head. The air inlet pipe is connected to the wind guiding ring, and the wind guiding ring is evenly fixed in the drying box. Spray heads are fixed at equal angles on the inner side of the wind guiding ring. Through the above structure, dry hot air can be sent into the drying box, thus providing a basic guarantee for realizing the drying of the material.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The masterbatch drying system adopts a vibrating material shaking mechanism, which can not only achieve the function of shaking and dispersing the materials to avoid material adhesion, but also increase the retention time of the materials in the drying box, thereby increasing the drying time and improving the drying effect of the materials. Specifically, by driving the elliptical wheel to rotate with a motor, and coordinating the sliding action between the elliptical wheel and the fixed rod and the elastic action of the spring, the shaking plate can move up and down orderly. Through the up and down movement of the shaking plate, the function of shaking and dispersing the materials can be achieved. And during the process of shaking and dispersing the materials, some materials fall through the feeding port, and some materials continue to fall onto the shaking plate for the next shaking, so as to ensure the drying effect of the materials. Moreover, when the shaking plate moves, the spring can be protected in cooperation with the cylinder, avoiding the adhesion of materials on the spring and affecting the normal operation of the device;

[0018] 2. The masterbatch drying system adopts a linked material distribution mechanism, which can not only achieve the function of intermittent feeding to avoid excessive feeding at one time and affecting the drying effect, but also loosen the materials to avoid material adhesion and affecting the normal feeding function. It can also strike the materials splashed by the shaking of the shaking plate to further disperse the materials and avoid material adhesion. Specifically, when the upper shaking plate moves up and down, it can drive the rotating shaft and the baffle to move, thereby realizing the opening and closing of the feeding pipe, and then realizing intermittent feeding. When the lower shaking plate moves up and down, in cooperation with the sliding rod, the spiral groove and the round rod, the rotating shaft, the distribution plate and the striking plate can be rotated. Through the centrifugal action of the distribution plate, the materials are evenly dispersed around. In cooperation with the function of the striking plate, the function of striking and dispersing the splashed materials can be achieved;

[0019] 3. The masterbatch drying system adopts a linked cleaning mechanism, which can effectively avoid the blockage of the feeding port by materials and affect the normal operation of the device. Specifically, when the shaking plate moves up and down, in cooperation with the transmission of the connecting rod, the fixed frame and the movable block move. In cooperation with the sliding action between the movable block and the feeding port, the blocked materials in the feeding port can be pushed and cleaned to ensure the normal operation of the device.

Specific embodiments

[0029] Please refer to Figures 1 - 7, the present invention provides a technical solution: a masterbatch drying system, including a drying box 1 and a motor 2.

The material shaking plate 401 is equally angularly fixed with cylinders 403. The material shaking plate 401 is slidably connected with a vertical rod 404 fixed inside the drying box 1. A circular plate 405 is fixed on the vertical rod 404, and the circular plate 405 is slidably connected inside the cylinder 403.

A fixed rod 407 is fixed on the material shaking plate 401, and the fixed rod 407 is slidably connected with the elliptical wheel 3.

[0030] An inlet pipe 101 is arranged at the upper end of the drying box 1, and the inlet pipe 101 is connected with a hopper 102. An exhaust hole 103 is installed at the upper end of the drying box 1, and an outlet 104 is installed at the lower end of the drying box 1. And an air supply mechanism 7 is fixed inside the drying box 1; The material distributing mechanism 6 includes a rotating shaft 601, a baffle 602, a loosening rod 603, a material distributing plate 604, a striking plate 605, a round rod 606, a spiral groove 607 and a sliding rod 608. The sliding rod 608 is made of high-strength alloy steel. The rotating shaft 601 is connected with the upper material shaking plate 401 through a bearing, and the rotating shaft 601 is slidably connected with the lower material shaking plate 401. And a baffle 602 is fixed on the rotating shaft 601, and at the same time, the baffle 602 cooperates with the inlet pipe 101 to achieve a sealing effect; A loosening rod 603 is fixed on the baffle 602, and the loosening rod 603 is arranged inside the hopper 102; A material distributing plate 604 is fixed on the rotating shaft 601, and strip-shaped holes are evenly opened on the material distributing plate 604. A striking plate 605 is also fixed on the rotating shaft 601; A round rod 606 is fixed at the lower end of the rotating shaft 601, and a spiral groove 607 is opened on the round rod 606, and the spiral groove 607 is slidably connected with the sliding rod 608. At the same time, the sliding rod 608 is fixed on the lower material shaking plate 401; The air supply mechanism 7 includes an air inlet pipe 701, a wind guiding ring 702 and a spray head 703. The air inlet pipe 701 is connected with the wind guiding ring 702, and the wind guiding ring 702 is evenly fixed inside the drying box 1. And spray heads 703 are evenly angularly fixed inside the wind guiding ring 702;

[0031] When using this masterbatch drying system, such as Figures 1 - 7As shown, the air inlet pipe 701 is connected to the hot air delivery pipe. At this time, hot air enters through the air inlet pipe 701 and is dispersed into the air guide ring 702, and is ejected through the nozzle 703, thus providing a basic guarantee for the drying of the masterbatch. When drying the masterbatch, the masterbatch to be dried is placed in the hopper 102 for storage, and then the motor 2 is controlled to start. The elliptical wheel 3 is driven by the motor 2 to rotate. During the rotation of the elliptical wheel 3, when the fixed rod 407 slides from the flat side to the convex side of the elliptical wheel 3, the fixed rod 407 is forced to move, thereby driving the upper and lower two vibrating plates 401 to move towards each other, and the spring 406 is forced to contract. When the fixed rod 407 slides from the convex side to the flat side of the elliptical wheel 3, at this time, due to the elastic action of the spring 406, the vibrating plate 401 is reset. According to the above principle, the vibrating plate 401 can perform orderly up and down movements. When the vibrating plate 401 moves, the sliding guiding effect between the vibrating plate 401 and the vertical rod 404 can ensure the stability of the movement of the vibrating plate 401. And when the upper vibrating plate 401 moves, it can synchronously drive the rotating shaft 601, the baffle 602, the loosening rod 603, the material distribution plate 604, the striking plate 605, the round rod 606 and the spiral groove 607 to move. The sliding effect between the rotating shaft 601 and the lower vibrating plate 401 can ensure the stability of the movement of the rotating shaft 601. When the rotating shaft 601 and the baffle 602 move upward, at this time, the baffle 602 is separated from the feed pipe 101, and the closing effect of the feed pipe 101 is released, so that the material in the hopper 102 can fall into the drying box 1. When the rotating shaft 601 and the baffle 602 move downward, at this time, the baffle 602 is reset to block the hopper 102, thereby realizing the intermittent feeding function, avoiding excessive feeding at one time and affecting the drying effect. And when the rotating shaft 601 and the baffle 602 move upward, at this time, the round rod 606 and the spiral groove 607 move upward synchronously, while the sliding rod 608 moves downward with the lower vibrating plate 401. With the sliding effect between the sliding rod 608 and the spiral groove 607, the rotating shaft 601, the baffle 602, the loosening rod 603, the material distribution plate 604 and the striking plate 605 are rotated. Thus, when the feed pipe 101 is opened, through the rotating action of the loosening rod 603, the masterbatch in the hopper 102 can be stirred, effectively avoiding the adhesion between the masterbatches and normal feeding. And the material entering through the feed pipe 101 first falls onto the material distribution plate 604. Through the bar holes on the material distribution plate 604, part of the masterbatch directly falls onto the upper vibrating plate 401 through the bar holes on the material distribution plate 604. Part of the masterbatch is dispersed around under the rotational centrifugal force of the material distribution plate 604, so that the falling masterbatch can be evenly dispersed onto the upper vibrating plate 401. Combined with the hot air ejected by the nozzle 703, the drying of the masterbatch can be realized. When the masterbatch falls onto the upper vibrating plate 401, due to the orderly up and down reciprocating movement of the upper vibrating plate 401, the throwing and shaking and dispersing effect of the masterbatch can be realized. And when the upper vibrating plate 401 throws the masterbatch upward,With the function of the striking plate 605, the masterbatch can be dispersed once to avoid adhesion. The masterbatch struck by the striking plate 605 has a certain potential energy and falls onto the upper vibrating plate 401 after colliding with the inner wall of the drying box 1, which can achieve the secondary collision and dispersion effect of the masterbatch, thus effectively avoiding the adhesion of the masterbatch. When the masterbatch falls onto the upper vibrating plate 401, a part of it falls onto the lower vibrating plate 401 through the material discharge opening 402 on the upper vibrating plate 401, and a part of it falls onto the upper vibrating plate 401 again, and then the secondary throwing and dispersing effect is carried out. Moreover, for the masterbatch falling onto the lower vibrating plate 401, through the up and down movement of the lower vibrating plate 401, the throwing and dispersing effect is carried out again. This can not only effectively ensure the dispersion effect of the masterbatch and the production quality of the masterbatch, but also extend the retention time of the masterbatch in the drying box 1 to ensure the drying effect of the masterbatch. Finally, the dried masterbatch falls through the material discharge opening 402 on the lower vibrating plate 401 and is discharged through the discharge port 104 for collection;

[0032] The material cleaning mechanism 5 includes a circular ring 501, a connecting rod 502, a fixing frame 503, a guide rod 504 and a movable block 505. The circular ring 501 is fixed on the vertical rod 404, and the circular ring 501 and the vibrating plate 401 are distributed in a one-to-one correspondence. Moreover, one end of the circular ring 501 is rotatably connected to the connecting rod 502, and the other end of the connecting rod 502 is rotatably connected to the fixing frame 503. The fixing frame 503 and the material discharge opening 402 are distributed in a one-to-one correspondence; the fixing frame 503 and the guide rod 504 are slidably connected, and the guide rod 504 is fixed on the vibrating plate 401; the fixing frame 503 is fixed with a movable block 505, and the movable block 505 and the material discharge opening 402 are slidably connected, and the two ends of the movable block 505 are gradually narrowed in width;

[0033] During the drying process of the masterbatch, as Figures 1 - 7 shown, when the vibrating plate 401 moves up and down, with the transmission function of the connecting rod 502, the fixing frame 503 and the movable block 505 move in an orderly reciprocating manner. With the sliding guiding function between the fixing frame 503 and the guide rod 504, the stability of the movement of the fixing frame 503 and the movable block 505 can be ensured. During the movement of the movable block 505, through the sliding action between the movable block 505 and the material discharge opening 402, the blocked masterbatch in the material discharge opening 402 can be extruded and removed to ensure the normal operation of the device. Moreover, through the reciprocating movement of the movable block 505, when the falling masterbatch contacts the movable block 505, through the movement of the movable block 505, the masterbatch can be struck at different angles, which can not only make the masterbatch more evenly dispersed in the drying box 1 to ensure the drying effect, but also through the movement of the movable block 505, part of the material discharge opening 402 can be blocked, further reducing the falling speed of the masterbatch through the material discharge opening 402, thereby further increasing the drying time of the masterbatch and ensuring the drying effect of the masterbatch. This is the working principle of the masterbatch drying system.

[0034] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
