Description

Technical Field

[0001] This utility model belongs to the technical field of drying equipment, specifically a drying device for processing plastic masterbatch. Background Technology

[0002] Plastic masterbatch is a special colorant for polymer materials, mainly used for coloring plastic products. It usually selects the same resin as the product resin as the carrier to ensure compatibility and flowability. It usually includes two categories: organic pigments and inorganic pigments.

[0003] In current technologies, drying devices for plastic masterbatch processing typically use resistance heating or increased ventilation to reduce the moisture inside the plastic masterbatch, thereby achieving the drying function and facilitating subsequent processing of the plastic masterbatch.

[0004] Existing drying devices for plastic masterbatch processing often result in uneven drying because the common resistance heating method causes heat to accumulate in a fixed location. Consequently, the plastic masterbatch closer to the heating device dries faster than that further away, leading to uneven drying. Therefore, a new drying device for plastic masterbatch processing is proposed to address this problem. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-4 This utility model provides a drying device for processing plastic masterbatch, including a device base 1; an auxiliary plate 2 is fixedly connected to the top of the device base 1; the auxiliary plate 2 has a sliding groove 10; a sliding block 9 is slidably connected to the inner wall of the auxiliary plate 2; a DC motor 19 is installed on the side of the sliding block 9; a drying barrel 3 is fixedly connected to the output end of the DC motor 19 through the sliding block 9; the drying barrel 3 is rotatably connected between the sliding blocks 9; a sliding rod 20 is fixedly connected to the bottom of the sliding block 9; an inner sliding rod 21 is slidably connected to the inner wall of the sliding rod 20; the inner sliding rod 21 is fixedly connected to the inner wall of the auxiliary plate 2; a spring 22 is fixedly connected to the sliding block 9 through the auxiliary plate 2; and a spring 22 is installed on the inner wall of the auxiliary plate 2. There is a trigger-type master switch 23; the trigger-type master switch 23 is electrically connected to the DC motor 19; during operation, when no plastic masterbatch is poured into the drying barrel 3, the sliding block 9 will rise due to the elastic force of the spring 22 and will no longer abut against the trigger-type master switch 23, thereby de-energizing the DC motor 19 and preventing it from starting arbitrarily. Until the drying barrel 3 is filled with plastic masterbatch for drying, the sliding block 9 is affected by its weight, causing the sliding block 9 to descend and compress the spring 22. At the same time, the sliding block 9 abuts against the trigger-type master switch 23, so that the trigger-type master switch 23 is activated, putting the DC motor 19 in a energized state, thereby allowing the DC motor 19 to start and rotate the drying barrel 3 to turn the material.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, a resistance heater 6 is installed on the outer wall of the drying barrel 3; the resistance heater 6 is electrically connected to the trigger-type master control switch 23; the resistance heater 6 is provided with multiple exhaust holes 7; a servo motor 8 is installed at the bottom of the drying barrel 3; a motor bevel gear 16 is fixedly connected to the output end of the servo motor 8; an external rod 11 is rotatably connected to the inner wall of the drying barrel 3; an internal rod 12 is rotatably connected to the inner wall of the external rod 11; a second bevel gear 18 is fixedly connected to one end of the internal rod 12; a first bevel gear 17 is fixedly connected to the outer wall of the external rod 11; the second bevel gear 18 and the first bevel gear 17 respectively mesh on the outer wall of the motor bevel gear 16; a first crushing rod 14 is fixedly connected to the outer wall of the external rod 11; an auxiliary frame 13 is fixedly connected to the other end of the internal rod 12; a second crushing rod 15 is fixedly connected to the side of the auxiliary frame 13; a feed pipe 4 is connected to the top of the drying barrel 3; a closing cover 5 is threadedly connected to the top of the feed pipe 4. During operation, plastic masterbatch can be poured into the device through the feed pipe 4. The resistance heater 6 and the exhaust port 7 are installed to heat and dry the material and expel humid air. When the servo motor 8 is started, the motor bevel gear 16 rotates. Since the first bevel gear 17 and the second bevel gear 18 mesh on both sides of the motor bevel gear 16, the first bevel gear 17 and the second bevel gear 18 will rotate in different directions. This will also cause the external rod 11 and the internal rod 12 to rotate in different directions, resulting in the first crushing rod 14 and the second crushing rod 15 rotating in different directions, thus breaking up the clumps of plastic masterbatch.

[0028] Working principle: When no plastic masterbatch is poured into the drying drum 3, the sliding block 9 will rise due to the elastic force of the spring 22, no longer resisting the trigger-type master control switch 23, thus de-energizing the DC motor 19 and preventing it from starting arbitrarily. When the drying drum 3 is filled with plastic masterbatch for drying, the sliding block 9, under its own weight, descends and compresses the spring 22, simultaneously causing the sliding block 9 to resist the trigger-type master control switch 23. This activates the trigger-type master control switch 23, energizing the DC motor 19, allowing it to start and rotate the drying drum 3 to turn the material along the feed pipe 4. Plastic masterbatch is poured into the device. The resistance heater 6 and the exhaust port 7 are installed to heat and dry the material and expel humid air. When the servo motor 8 is started, the motor bevel gear 16 rotates. Since the first bevel gear 17 and the second bevel gear 18 are meshed on both sides of the motor bevel gear 16, the first bevel gear 17 and the second bevel gear 18 will rotate in different directions. At the same time, the external rod 11 and the internal rod 12 will also rotate in different directions. As a result, the first crushing rod 14 and the second crushing rod 15 will rotate in different directions, thereby breaking up the plastic masterbatch clumps.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
