Description

Technical Field

[0001] This utility model relates to the field of plastic raw material preheating and drying technology, specifically a plastic plug raw material preheating and drying device. Background Technology

[0002] In the production process of plastic plugs, the preheating and drying of raw materials is a crucial preliminary step, and its treatment effect directly affects the quality of subsequent molded products and production efficiency.

[0003] Taking patent CN222610114U as an example, the porous conveyor belt preheating and transmission method it adopts results in uneven distribution of raw materials on the conveyor belt, leading to differences in the contact area and time between hot air and raw materials, which can easily cause uneven heating and drying of raw materials.

[0004] Furthermore, the simple design of the stirring structure in this device prevents the raw materials from being thoroughly turned and mixed, leading to low heating efficiency and unstable drying quality. With the increasing demands for product precision and production efficiency in the plastics processing industry, there is an urgent need for a new type of preheating and drying device that can achieve uniform heating and efficient drying of raw materials to address the shortcomings of existing technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a preheating and drying device for plastic plug raw materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A preheating and drying device for plastic plug raw materials includes: a box body, gear one, gear two, and gear three. The front side of the box body is hollowed out. A feed inlet is provided at the upper left end of the box body, and a discharge outlet is provided at the lower right end of the box body. A rotary motor is provided in the middle of the upper end face of the box body. The rotating shaft of the rotary motor is fixedly connected to gear one. A first stirring fan blade group and a second stirring fan blade group are provided on the inner wall of the rear side plate of the box body. The rotating shaft of the stirring fan blade group passes through a circular bearing on the box body and is fixedly connected to gear two and gear three respectively. Gear one and gear two are both meshed with gear three. Hot air assembly one and hot air assembly two are provided on the left and right sides of the upper end face of the box body respectively. The hot air assembly is used to blow hot air into the box body to dry the plastic plug raw materials. A heating assembly is provided on the front side of the box body.

[0008] The mixing fan blade assembly is used to mix and transport the plastic plug material. The inlet and outlet are connected to the box body. Hot air assembly one and hot air assembly two have the same structure and work simultaneously. The heating assembly is embedded in the front of the box body and is used to heat the plastic plug material.

[0009] Preferably, the heating assembly contains a main unit that controls the operation of the rotary motor, hot air assembly one, and hot air assembly two. A touch screen is located on the front of the heating assembly, and multiple heating plates are located on the rear of the heating assembly. The heating plates are used to uniformly heat the plastic plug material at a certain temperature after being powered on. The touch screen is used to monitor the temperature of the plastic plug material inside the chamber and simultaneously control the rotation speed of the rotary motor, the power of the hot air assembly, and the power of the heating plates.

[0010] Preferably, the second hot air assembly includes a hot air blower and an air outlet hood. Multiple air outlet hoods connected to the housing are provided on the left and right sides of the upper end face of the housing. A hot air blower is provided on the left side of the second hot air assembly. After the infrared heating tube inside the hot air blower heats up, a strong airflow is generated by a centrifugal fan. The air outlet of the hot air blower is connected to multiple air outlet hoods through a pipe.

[0011] Preferably, base supports are provided on both the left and right sides of the bottom surface of the box, and the base supports are used to support the box.

[0012] Preferably, a valve is provided at the discharge port. When the valve is closed, preheating and drying are performed, and when the valve is opened, material is discharged.

[0013] Compared with the prior art, this utility model provides a preheating and drying device for plastic plug raw materials, which has the following beneficial effects:

[0014] The rotary motor drives gear one to rotate via a rotating shaft. Gear one, gear two, and gear three mesh with each other, thereby driving the first and second stirring fan blade groups on the inner wall of the rear side plate of the housing to rotate synchronously.

[0015] This gear transmission structure enables the stirring fan assembly to agitate the plastic plug material inside the chamber at a stable rotation speed from multiple angles and directions. During the agitation process, the stirring fan assembly not only fully disperses the accumulated material, but also ensures that each part of the material can be in maximum contact with the hot air blown out by the hot air assembly and the heat generated by the heating assembly, achieving the goal of uniform heating and avoiding the problem of localized overheating or incomplete drying caused by material accumulation as described in patent CN222610114U.

[0016] In summary, this device, through the innovation of the stirring fan blade assembly, achieves uniform heating of raw materials while efficiently completing material transfer, thus improving the preheating and drying effect of raw materials for plastic plugs. Attached Figure Description

Detailed Implementation

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-6As shown, this embodiment of a plastic plug raw material preheating and drying device includes a housing 1. The front side of the housing 1 is hollowed out, with a feed inlet 401 at the upper left end and a discharge outlet 402 at the lower right end. A rotary motor 2 is fixedly installed in the middle of the upper end face, and the rotating shaft of the rotary motor 2 is fixedly connected to the center of gear 1 701. A first stirring fan blade group 801 and a second stirring fan blade group 802 are arranged in parallel on the inner wall of the rear side plate of the housing 1. The rotating shafts of the two fan blade groups pass through the circular bearings of the rear side plate of the housing 1, and the ends are fixedly connected to gear 2 702 and gear 3 703 in sequence. Gear 1 701 and gear 2 702 are both meshed with gear 3 703 to form a single-stage gear transmission structure. Hot air assembly 1 (301) and hot air assembly 2 (302) are symmetrically arranged on the left and right sides of the upper end face of the housing 1. Each hot air assembly includes a hot air blower and multiple air outlet hoods (303). The hot air blower is connected to the air outlet hoods (303) through pipes and is used to blow hot air into the housing 1. A heating assembly 6 is embedded in the front side of the housing 1. The main unit inside the heating assembly 6 is electrically connected to the rotary motor 2 and the hot air assembly. A touch screen display 601 is set on the front side, and multiple heating plates 603 are fixed on the rear side. The heating plates 603 are attached to the inner wall of the front side of the housing 1 and are used to preheat the raw materials. The base bracket 5 is fixed to the left and right sides of the bottom surface of the housing 1 by bolts. An electric valve is installed at the discharge port 402 and is controlled to open and close by the main unit.

[0026] During operation, the raw material with the plastic plug is poured into the housing 1 through the inlet 401. The main unit starts the rotary motor 2, which drives gears 702 and 703 to rotate in opposite directions via gear 1 701. This causes the first stirring fan blade group 801 and the second stirring fan blade group 802 to cross-stir the raw material at the same speed. At the same time, the hot air assembly and the heating assembly 6 work synchronously. Hot air is blown evenly into the housing 1 from the top, and the heating plate 603 provides radiant heat from the front, forming a three-dimensional heating environment. The raw material moves slowly from left to right under the push of the stirring fan blade group and is finally discharged from the outlet 402, realizing integrated preheating and drying treatment.

[0027] In some examples, the hot air assembly's exhaust hood 303 has a removable filter inside. The filter is made of stainless steel wire mesh and can filter dust and impurities in the hot air to prevent contamination of raw materials. The filter is connected to the exhaust hood 303 by a snap-fit, making it easy to remove and clean regularly.

[0028] In some examples, the heating plate 603 integrates a temperature sensor, which can collect the temperature of the upper, middle and lower layers of raw materials in the chamber 1 in real time. The temperature parameters are sent to the host, and the host automatically adjusts the speed of the rotary motor 2 and the power of the hot air component through the host algorithm to keep the temperature difference of the raw materials in each layer within 2°C, so as to achieve precise temperature control.

[0029] The working principle of this utility model is as follows:

[0030] First, place the device stably on a level surface using the base support 5, which provides stable support. Set the preheating and drying parameters via the touchscreen display 601, including the rotation speed of the rotary motor 2, the power of the hot air assembly, the temperature of the heating plate 603, and the target drying time. Ensure the valve at the discharge port 402 is closed to prevent premature discharge of raw materials during the preheating and drying process. Then, pour the raw material from the plastic plug into the box 1 through the inlet 401 at the upper left side. The material falls into the central area of ​​the box 1 through the inlet 401, and the initial accumulation of material is initially received by the first stirring blade assembly 801 and the second stirring blade assembly 802.

[0031] The main unit inside the heating assembly 6 is activated, and the main unit controls the rotary motor 2 to start running. The shaft of the rotary motor 2 drives gear 1 701 to rotate clockwise. Since gear 1 701 and gear 2 702 are both meshed with gear 3 703, gear 1 701 drives gear 2 702 to rotate counterclockwise through gear 3 703, thereby causing the first stirring blade group 801 and the second stirring blade group 802, which are fixed on gear 2 702 and gear 3 703, to rotate synchronously in opposite directions. The blades of the two stirring blade groups are staggered at a certain angle, generating bidirectional shear force on the raw materials when rotating: on the one hand, it lifts and throws the accumulated raw materials upward, breaking up the raw material clumps; on the other hand, the axial thrust generated by the blade inclination angle pushes the raw materials to move slowly from the left side to the right side of the box 1. Under the stable drive of the gear transmission, the raw materials are continuously stirred at multiple angles and directions, ensuring that each part of the raw materials can break away from the initial piled state and form a uniformly dispersed fluidized motion.

[0032] While the stirring fan assembly is operating, hot air assembly 1 (301) and hot air assembly 2 (302) start simultaneously: the infrared heating tubes inside the hot air blower heat to the set temperature, generating a strong airflow through a centrifugal fan. The hot air is evenly blown into the chamber 1 through multiple air outlets 303 on the left and right sides of the upper end face of the chamber 1 via pipes, forming a top-down hot air circulation. At the same time, multiple heating plates 603 on the rear side of the heating assembly 6 are energized and radiate heat to the front of the chamber 1 at the same temperature, forming a three-dimensional heating environment with the top hot air convection. Under the stirring of the fan assembly, the raw materials are constantly in contact with the hot air and heating plates 603, and the moisture evaporates quickly. The touch display screen 601 monitors the temperature sensor data of the upper, middle and lower layers inside the chamber 1 in real time. When the temperature deviation in a certain area exceeds 2°C, the main unit automatically adjusts the speed of the rotary motor 2 and the power of the hot air assembly to ensure uniform heating of the raw materials.

[0033] Under the action of the stirring blade assembly, the raw material gradually moves from the upper left side of the inlet 401 to the lower right side of the outlet 402. During the entire transfer process, the raw material undergoes continuous stirring and heating for a certain period of time until it reaches the preset drying standard. When the touch display 601 detects that the raw material temperature has stabilized at the target drying temperature for a certain period of time, the main unit issues a command to open the valve of the outlet 402. The dried raw material is discharged from the outlet 402 under the force of gravity and the push of the stirring blade assembly, and enters the subsequent molding process.

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