Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, and in particular relates to a drying device for plastic processing equipment. Background Technology

[0002] In the plastics processing industry, the pretreatment of plastic raw materials plays a crucial role in ensuring the quality and performance of the final product. During storage and transportation, plastic raw materials easily absorb moisture from the air. The presence of moisture can have many adverse effects on the plastic processing process and product quality. When plastic raw materials containing moisture are processed, the moisture will vaporize and form bubbles in the high-temperature molten state, resulting in defects such as pores and bubbles on the surface of plastic products, which seriously affects the appearance quality of the products. At the same time, the presence of moisture will also change the viscosity of the plastic melt, affecting its fluidity and molding performance, which will lead to a decrease in product dimensional accuracy and a deterioration in mechanical properties, such as reduced strength and toughness. It may even cause equipment failure during processing and reduce production efficiency.

[0003] According to the announcement, a drying device for engineering plastic processing equipment (publication number: CN 209191054U) includes a base, a drying shell, an electric heating layer, a blower, a stirring motor, a drying pipe, a hydraulic cylinder, a PLC control cabinet, and a discharge port. A first connecting seat and a second connecting seat are installed on the lower side of the drying shell. A connecting shaft is installed on one side of the upper end of the base, and the first connecting seat is hinged to the connecting shaft. A hydraulic cylinder is installed at one end of the base, and a telescopic rod is driven to the upper side of the hydraulic cylinder. The upper end of the telescopic rod is hinged to the second connecting seat. A stirring motor is installed on the outer side of one end of the drying shell, and an electric heating layer is installed inside the drying shell.

[0004] However, in the above design, during the drying process of plastic, the plastic accumulates in the lower half of the bucket, and when the plastic is stirred, it cannot be effectively and evenly dispersed, resulting in uneven drying, which needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a drying device for plastic processing equipment. Through the driving force of the motor, the motor, rotating shaft, stirring plate, transmission gear, connecting gear, fixed shaft, reciprocating screw, reciprocating sleeve, push plate and other components work together to start the motor that runs through the side of the support plate. The rotation of the motor drives the rotating shaft fixed at the end of the output shaft to rotate inside the heating cylinder, thus solving the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a drying device for plastic processing equipment, comprising a base and a support plate. The support plate is fixedly connected to the top of the base. A heating cylinder is rotatably connected to the side of the support plate. A feed inlet is located on the circumferential surface of the heating cylinder. A self-locking plate is provided on the circumferential surface of the heating cylinder. A uniform drying mechanism is provided inside the heating cylinder. The uniform drying mechanism includes a motor, which passes through the side of the support plate. A rotating shaft is fixedly connected to the end of the output shaft of the motor. A stirring plate is fixedly connected to the circumferential surface of the rotating shaft. A transmission gear is fixedly connected to the circumferential surface of the rotating shaft. A fixed shaft is rotatably connected to the inner wall of the heating cylinder. A reciprocating lead screw is fixedly connected to the circumferential surface of the fixed shaft. A reciprocating threaded sleeve is threaded to the circumferential surface of the reciprocating lead screw. A push plate is fixedly connected to the bottom of the reciprocating threaded sleeve. A connecting gear is fixedly connected to the circumferential surface of the fixed shaft.

[0008] Furthermore, a support bracket is fixedly connected to the bottom of the base, a limit rod is fixedly connected to the inner wall of the heating cylinder, and a limit plate is fixedly connected to the side of the reciprocating thread sleeve. The above design is conducive to the uniform drying of plastic.

[0009] Furthermore, the side cross-section of the reciprocating threaded sleeve is set to a rectangle, the limiting plate is slidably connected to the circumferential surface of the limiting rod, and the rotating shaft passes through the side of the heating cylinder. The above design is conducive to making the reciprocating threaded sleeve perform linear reciprocating motion.

[0010] Furthermore, the number of support plates is set to two, and the transmission gear and the connecting gear mesh with each other. The above design is beneficial because when the transmission gear rotates, it drives the connecting gear to rotate.

[0011] Furthermore, a temperature control mechanism is provided on the circumferential surface of the heating cylinder. The temperature control mechanism includes a hollow block that extends through the circumferential surface of the heating cylinder. An air vent plate is fixedly connected to the inner side wall of the hollow block. The above design helps to prevent the plastic from melting due to excessively high temperature.

[0012] Furthermore, a spring is fixedly connected to the side of the air vent plate, and a blocking plate is fixedly connected to the end of the spring away from the air vent plate. The above design is beneficial for automatic cooling when the temperature exceeds the threshold.

[0013] Furthermore, the blocking plate is slidably connected to the inner wall of the hollow block, which passes through the circumferential surface of the heating cylinder and is fixedly connected to the heating cylinder. This design helps to enhance the stability of the temperature control mechanism.

[0014] Furthermore, the number of support legs is set to several, and they are symmetrical to each other along the vertical central axis at the bottom of the base. This design helps to enhance the stability of the base.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses the driving force of an electric motor to drive the motor, rotating shaft, stirring plate, transmission gear, connecting gear, fixed shaft, reciprocating screw, reciprocating sleeve, push plate and other components to cooperate with each other, so as to start the motor that runs through the side of the support plate. The rotation of the motor drives the rotating shaft fixed at the end of the output shaft to rotate inside the heating cylinder. When the rotating shaft rotates, it drives the stirring plate fixed on the circumferential surface to make a circular motion to stir the material. When drying plastic, it prevents uneven stirring of plastic.

[0017] 2. This utility model uses air pressure to drive components such as the hollow block, air passage plate, spring, and blocking plate to work together. When the temperature and pressure inside the heating cylinder are too high, the air pressure enters the interior of the hollow block through the air passage plate fixed to the inner wall of the hollow block. At this time, the blocking plate slides on the inner wall of the hollow block under the pushing force of the air pressure, preventing the plastic from melting due to excessive temperature during the drying process.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-5 As shown, this utility model is a drying device for plastic processing equipment, including a base 1 and a support plate 2. The support plate 2 is fixedly connected to the top of the base 1. A heating cylinder 3 is rotatably connected to the side of the support plate 2. A feed inlet 4 is located on the circumferential surface of the heating cylinder 3. A self-locking plate 5 is provided on the circumferential surface of the heating cylinder 3. A uniform drying mechanism 6 is provided inside the heating cylinder 3. The uniform drying mechanism 6 includes a motor 61, which passes through the side of the support plate 2. A rotating shaft 62 is fixedly connected to the end of the output shaft of the motor 61. A stirring plate 63 is fixedly connected to the circumferential surface of the rotating shaft 62. A transmission gear 64 is fixedly connected to the circumferential surface of the rotating shaft 62. A fixed shaft 65 is rotatably connected to the inner wall of the heating cylinder 3. A reciprocating screw 66 is fixedly connected to the circumferential surface of the fixed shaft 65. A reciprocating threaded sleeve 67 is threadedly connected to the circumferential surface of the reciprocating screw 66. A push plate 68 is fixedly connected to the bottom of the reciprocating threaded sleeve 67. A connecting gear 69 is fixedly connected to the circumferential surface of the fixed shaft 65.

[0029] The bottom of the base 1 is fixedly connected to a support bracket 8, the inner wall of the heating cylinder 3 is fixedly connected to a limit rod 610, and the side of the reciprocating thread sleeve 67 is fixedly connected to a limit plate 611. The above design is conducive to the uniform drying of plastic.

[0030] The side section of the reciprocating threaded sleeve 67 is set as rectangular, the limiting plate 611 is slidably connected to the circumferential surface of the limiting rod 610, and the rotating shaft 62 passes through the side of the heating cylinder 3. The above design is conducive to making the reciprocating threaded sleeve 67 perform linear reciprocating motion.

[0031] The number of support plates 2 is set to two, and the transmission gear 64 and the connecting gear 69 mesh with each other. The above design is beneficial to drive the connecting gear 69 to rotate when the transmission gear 64 rotates.

[0032] A temperature control mechanism 7 is provided on the circumferential surface of the heating cylinder 3. The temperature control mechanism 7 includes a hollow block 71, which runs through the circumferential surface of the heating cylinder 3. An air vent plate 72 is fixedly connected to the inner side wall of the hollow block 71. The above design helps to prevent the plastic from melting due to excessive temperature.

[0033] A spring 73 is fixedly connected to the side of the air vent plate 72, and a blocking plate 74 is fixedly connected to the end of the spring 73 away from the air vent plate 72. The above design is beneficial for automatic cooling when the temperature exceeds the threshold.

[0034] The blocking plate 74 is slidably connected to the inner wall of the hollow block 71, which runs through the circumference of the heating cylinder 3 and is fixedly connected to it. This design helps to enhance the stability of the temperature control mechanism 7.

[0035] The number of support legs 8 is set to several, and they are symmetrical to each other along the vertical central axis of the bottom of the base 1. The above design helps to enhance the stability of the base 1.

[0036] A specific application of this embodiment is as follows: When drying plastic is required, the operator flips the self-locking plate 5, thereby removing the seal from the feed inlet 4. The operator then pours material into the feed inlet 4. After feeding is complete, the operator closes the self-locking plate 5, sealing the feed inlet 4. Simultaneously, the motor 61, which runs through the side of the support plate 2, is activated. The motor 61 rotates, causing the rotating shaft 62, fixed at the end of the output shaft, to rotate inside the heating cylinder 3. When the rotating shaft 62 rotates, it drives the stirring plate 63, fixed on the circumferential surface, to perform a circular motion to agitate the material. Simultaneously, the rotation of the rotating shaft 62 drives the transmission gear 64, fixed on the circumferential surface, to rotate. The rotation of the transmission gear 64 causes the meshing connecting gear 69 to be pushed, thereby causing the fixed shaft 65, rotating on the inner wall of the heating cylinder 3, to rotate. When the fixed shaft 65 rotates, it drives the reciprocating screw 66, fixed on the circumferential surface, to rotate, simultaneously driving the reciprocating threaded sleeve 67, threaded onto the circumferential surface, to move. The movement of the 67-axis motion drives the side limiting plate 611 to reciprocate linearly on the circumferential surface of the limiting rod 610, thereby causing the reciprocating threaded sleeve 67 to reciprocate linearly. When the reciprocating threaded sleeve 67 reciprocates linearly, it drives the push plate 68 fixed at the bottom to move, preventing material accumulation and ensuring effective drying. Finally, when the temperature and pressure inside the heating cylinder 3 are too high, the air pressure enters the interior of the hollow block 71 through the air passage plate 72 fixed to the inner wall of the hollow block 71. At this time, the blocking plate 74 slides on the inner wall of the hollow block 71 under the pushing force of the air pressure. When the blocking plate 74 slides, the spring 73 fixed to the side is in a stretched state. At the same time, when the blocking plate 74 slides to a certain position, the hollow block 71 is no longer in a sealed state, and the air pressure is discharged from the interior of the heating cylinder 3 through the hollow block 71. When the temperature returns to normal, the air pressure can no longer push the blocking plate 74. At this time, the spring 73 returns to its original position according to its own elasticity, thereby driving the blocking plate 74 to return to its original position, so that the hollow block 71 is in a sealed state.
