Description

Technical Field

[0001] This utility model belongs to the field of plastic particle processing technology, and specifically relates to a stirring device for a plastic particle dryer. Background Technology

[0002] The stirring device of a plastic particle dryer is the core component inside the dryer, which uses a screw rod to agitate and tumble the plastic particles. Its design purpose is to break the static accumulation state of the material through continuous mechanical movement, allowing the plastic particles to fully contact the drying hot air, thereby improving drying efficiency and uniformity.

[0003] Current mixing devices transport and mix plastic granules using a single screw, which can easily lead to dead zones during particle pushing, preventing the particles from fully contacting the hot air in the dryer, increasing drying time. Furthermore, the screw surface wears down over time, requiring users to stop the machine and disassemble multiple components such as bearings, seals, and transmission boxes for maintenance. A single maintenance session typically takes four to eight hours, impacting the drying efficiency of the plastic granules. Utility Model Content

[0004] The purpose of this utility model is to provide a stirring device for a plastic particle dryer. Its advantages are that it avoids the accumulation of plastic particles due to dead corners during stirring and allows for quick disassembly of the screw rod and the device after long-term use.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a stirring device for a plastic particle dryer, comprising a stirring tank, a drive motor fixedly installed on the right side of the top surface of the stirring tank, a transmission assembly rotatably connected to the right side of the top of the stirring tank, the transmission assembly comprising a drive wheel and a drive gear, the bottom of the drive wheel being rotatably connected to the stirring tank, a positioning plate being snapped into the top of the stirring tank, a connecting assembly being fixedly installed on the top of the positioning plate, the bottom of the positioning plate being snapped into the stirring tank, a stirring assembly being snapped into the bottom of the positioning plate, the stirring assembly comprising a fixed shell and a first spiral rod, the top of the fixed shell being slidably connected to the positioning plate, the bottom of the first spiral rod being slidably connected to the inner cavity of the stirring tank, an inlet shell communicating with the bottom of the front side of the stirring tank, and an outlet pipe communicating with the side of the front side of the stirring tank away from the inlet shell.

[0006] The above technical solution addresses the following: When it's necessary to prevent plastic particles from accumulating in dead corners during mixing, the user activates the transmission component. This component drives the mixing component to transport the plastic particles from the feed tank to the mixing drum. Subsequently, the planetary gear set formed by the gear ring, limit gear, and fixed gear in the mixing component simultaneously drives the first and second screw rods to transport the plastic particles, preventing accumulation in dead corners during mixing. For quick maintenance of the mixing component after prolonged use, the user disconnects the transmission component from the mixing component. Then, the user detaches the positioning plate from the mixing drum, releasing the locking plate and positioning shell from the mixing component, thus enabling quick maintenance after extended use.

[0007] The present invention is further configured such that the bottom of the transmission wheel is fixedly installed with the output end of the transmission motor, the top of the transmission wheel is rotatably connected to a limiting shell, the right side of the bottom of the limiting shell is slidably connected to the mixing tank, the right side of the top of the inner cavity of the limiting shell is slidably connected to the transmission gear, and a transmission belt is used to drive the transmission gear and the transmission wheel.

[0008] The above technical solution is adopted as follows: the transmission motor drives the transmission wheel to rotate, and the transmission wheel transmits power to the transmission gear through the transmission belt, realizing long-distance and precise power transmission. The limiting shell constrains the position of the transmission wheel and the transmission gear to avoid slippage and affect the transmission efficiency. The sliding connection between the limiting shell and the mixing tank facilitates the adjustment of the overall transmission position of the transmission component.

[0009] The present invention is further configured such that the connecting assembly includes two locking shells, the inner cavity of the locking shell is movably connected to the positioning plate through a shaft pin, the rear side of each locking shell is movably connected to a positioning shell, the bottom of the positioning shell is fixedly installed to the positioning plate, and the opposite side of the inner cavity of the positioning shell and the locking shell is engaged with the fixed shell.

[0010] The above technical solution is adopted: the locking shell connected by the shaft pin can rotate on the top of the positioning plate, forming a clamping space with the positioning shell, which clamps the stirring component to the bottom of the positioning plate, realizing a stable connection between the stirring component and the positioning plate, and also facilitating the quick assembly and disassembly of the stirring component and the positioning plate in the future.

[0011] The present invention is further configured such that a positioning plate is fixedly installed on the top of the positioning shell, and the inner cavity of the positioning plate is slidably connected to the positioning shell.

[0012] The above technical solution is adopted: the positioning plate slides on the top of the positioning shell and embeds into the positioning shell, locking the relative position of the positioning shell and the positioning shell, preventing them from separating due to vibration during the stirring process, and further strengthening the connection of the stirring components. The sliding operation of the positioning plate is convenient, and locking and unlocking can be completed quickly, which facilitates the disassembly and maintenance of the stirring components, taking into account both connection reliability and operational efficiency.

[0013] The present invention is further configured such that a toothed ring is engaged in the inner cavity of the fixed shell, two limiting gears mesh in the inner cavity of the toothed ring, a fixed gear meshes between the two limiting gears on opposite sides, the top of the limiting gear is slidably connected to the positioning plate, the top of the fixed gear is in contact with the positioning plate, the inner cavity of the fixed gear is engaged with a first spiral rod, a gear shaft is fixedly installed on the top of the fixed gear, the top surface of the gear shaft meshes with a transmission gear, and a second spiral rod is engaged in the inner cavity of the limiting gear.

[0014] The above technical solution is adopted: the fixed gear drives the transmission gear and the inner cavity of the gear shaft to rotate, and the fixed gear drives the two limit gears on both sides to revolve around it. At the same time, the meshing of the limit gears and the gear ring forms a planetary transmission structure, so that the screw rod driven by the fixed gear and the screw rod driven by the limit gear produce different speeds and directions, eliminating the dead angle of stirring, avoiding particle accumulation, and improving the drying uniformity.

[0015] The present invention is further configured such that a locking block is fixedly installed on the top of both the first and second spiral rods, and the surface of the locking block is respectively engaged with the inner cavity of the fixed gear and the limiting gear.

[0016] The above technical solution utilizes a snap-fit ​​structure between the locking block and the gear cavity to facilitate quick replacement and maintenance of either the first or second screw rod after prolonged use.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. When it is necessary to prevent plastic particles from accumulating in dead corners during mixing, the user can activate the transmission component to drive the mixing component to transport the plastic particles inside the feed tank to the mixing drum. Then, through the planetary gear set formed by the toothed ring, limit gear, and fixed gear in the mixing component, the screw rod one and screw rod two are driven to transport the plastic particles, preventing the plastic particles from accumulating in dead corners during mixing.

[0019] 2. When a quick maintenance of the mixing component is required after prolonged use, the user should disconnect the part connecting the transmission component and the mixing component from the mixing component. Then, the user should disconnect the positioning plate from the mixing tank and release the locking plate and positioning shell from the mixing component, thus completing the quick maintenance of the mixing component after prolonged use.
