Description

Technical Field

[0001] This utility model relates to the field of plastic granule production, and more specifically, it relates to a plastic granule raw material mixing device that prevents clogging. Background Technology

[0002] In the production of plastic pellets, it is usually necessary to mix various plastic pellet raw materials with different properties to meet the performance requirements of the product.

[0003] Then, because the plastic granules are irregularly shaped, they tend to accumulate inside the mixing tank when the feeding component adds them, leading to poor material conveying or even complete blockage. Secondly, in traditional mixing devices, the stirring position of the agitator is usually fixed. During the mixing process, when encountering plastic granules that are highly viscous or prone to clumping, the agitator with a fixed stirring position cannot generate sufficient impact and shear force on these granules, and cannot break up the material. At the same time, material tends to adhere to the blades, which in turn causes blockage of the mixing chamber due to particle accumulation.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a plastic granule raw material mixing device that prevents clogging. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plastic granule raw material mixing device that prevents clogging.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plastic granule raw material mixing device for preventing blockage, comprising a cylindrical mixing tank with an open top, a lifting platform driven by a reciprocating mechanism above the mixing tank, such that the lifting platform can move up and down slightly along the vertical direction of the mixing tank under the action of the reciprocating mechanism, a power device for driving the stirring paddle located below it to rotate is provided at the top of the lifting platform, and a feeding component is also installed on the lifting platform.

[0007] Preferably, the feeding assembly includes feeding pipes arranged in a circumferential array and embedded in the lifting platform, and each feeding pipe is equipped with a metering valve. The top ends of each feeding pipe are interconnected with a raw material storage tank, and the top end of the raw material storage tank is threadedly connected with a cover.

[0008] Preferably, the reciprocating mechanism includes a support plate fixed to the outer wall of the mixing tank, and a connecting shell with an open surface is provided on the support plate. A motor is installed on the inner bottom wall of the connecting shell, and a reciprocating lead screw is installed on the drive shaft of the motor. A rod sleeve is threaded onto the outer wall of the reciprocating lead screw. Guide rails for sliding of the slider are fixedly connected to both sides of the connecting shell. A connecting plate is fixedly connected between the slider and the rod sleeve, and a vertical rod is fixedly connected to the top of the connecting plate. A through slot for the vertical rod to pass through is opened on the top of the connecting shell. An mounting plate is fixedly connected to the side end of the lifting platform, and the head of the vertical rod is connected to the bottom of the mounting plate.

[0009] Preferably, the inner top wall of the connecting shell is rotatably connected to a reciprocating lead screw via a bearing.

[0010] Preferably, the mounting plate and the vertical rod are detachably connected.

[0011] Preferably, the bottom end of the mounting plate is fixedly connected to a frame-shaped slot, the top end of the vertical rod is fixedly connected to a connecting block that can be inserted into the frame-shaped slot, the top end of the connecting block is fixedly connected to a plurality of screws, the mounting plate is provided with through holes for the screws to pass through, and a nut is threaded onto the outer side wall of the screw.

[0012] Preferably, the surface of the mixing tank is provided with an observation window.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model uses a reciprocating mechanism to drive a lifting platform to make small-amplitude vertical movements along the mixing tank, thereby causing the stirring paddle and feeding assembly to move up and down slightly. When encountering plastic granules with high viscosity or easy clumping, the small-amplitude up and down movement of the stirring paddle can increase the impact and shearing force on these granules. When the upper blades move downward, they can apply greater pressure to the granules that are piled up or stuck to the bottom or inner wall of the mixing tank, breaking them up. When they move upward, they can shake off the granules attached to the blades, preventing the granules from accumulating on the blades, thus avoiding blockage of the mixing chamber due to granule accumulation and maintaining the smooth operation of the mixing device. At the same time, the up and down movement will also produce a vibration effect on the feeding assembly. The vibration can destroy the friction and accumulation structure between the granules, allowing the granules to enter the mixing tank more smoothly under the action of gravity, avoiding the accumulation of raw materials in the feeding assembly, thus solving the problems in the background art.

[0015] 2. In this utility model, the feeding pipes arranged in a circular array are embedded in the lifting platform, which allows various plastic granule raw materials to enter evenly from different positions on the top of the mixing tank, avoiding local accumulation, accelerating the dispersion speed of the raw materials, and creating good conditions for thorough mixing.

[0016] 3. In this utility model, the mounting plate and the vertical rod are detachably connected. During equipment maintenance and repair, if the reciprocating mechanism or the lifting platform malfunctions, the mounting plate and the vertical rod can be quickly separated, thereby removing the lifting platform and its connected structure from the mixing device for repair or replacement, which greatly shortens the maintenance time and also facilitates the cleaning of the stirring paddle connected to the lifting platform.

Detailed Implementation

[0024] like Figure 1-5 As shown, this utility model provides a plastic granule raw material mixing device for preventing blockage, including a cylindrical mixing tank 1 with an open top. A lifting platform 2 driven by a reciprocating mechanism 3 is provided above the mixing tank 1, so that the lifting platform 2 can move up and down slightly along the vertical direction of the mixing tank 1 under the action of the reciprocating mechanism 3. A power device 12 is provided at the top of the lifting platform 2 to drive the stirring paddle 4 located below it to rotate. A feeding component 5 is also installed on the lifting platform 2.

[0025] During operation, the reciprocating mechanism 3 drives the lifting platform 2 to make small-amplitude vertical movements along the mixing tank 1, thereby causing the stirring paddle 4 and the feeding component 5 to move up and down slightly. When encountering plastic granules with high viscosity or easy clumping, the small-amplitude up and down movement of the stirring paddle 4 can increase the impact and shearing force on these granules. When the blades move downward, they can apply greater pressure to the granules that are piled up or stuck to the bottom or inner wall of the mixing tank, breaking them up; when they move upward, they can shake off the granules attached to the blades, preventing the granules from accumulating on the blades, thus avoiding blockage of the mixing chamber due to granule accumulation and maintaining the smooth operation of the mixing device. At the same time, the up and down movement also produces a vibration effect on the feeding component 5 (the inertial force generated by the lifting directly acts on the feeding component 5, thus forming a vibration-like effect). The vibration can destroy the friction and accumulation structure between the granules, allowing the granules to enter the mixing tank 1 more smoothly under the action of gravity, avoiding the accumulation of raw materials in the feeding component 5.

[0026] Furthermore, the feeding assembly 5 includes feeding pipes 501 arranged in a circumferential array and embedded on the lifting platform 2. Each feeding pipe 501 is equipped with a metering valve 502. The top ends of each feeding pipe 501 are interconnected with raw material storage tanks 503, and the top ends of the raw material storage tanks 503 are threadedly connected to caps 504. In use, the caps 504 at the top of the raw material storage tanks 503 are opened, and various sufficient quantities of plastic granules are placed into different raw material storage tanks 503. The metering valves 502 control the flow of raw material from each feeding pipe 501 into the raw material storage tanks 503. The addition amount of various raw materials placed in the mixing tank 1 is precisely controlled. The feeding pipes 501, arranged in a circumferential array, are embedded in the lifting platform 2, which allows various plastic granule raw materials to enter evenly from different positions on the top of the mixing tank 1, avoiding local accumulation, accelerating the dispersion speed of raw materials, and creating good conditions for thorough mixing. In addition, the surface of the mixing tank 1 is provided with an observation window 11, through which the operator can observe the mixing status of the plastic granules in the tank in real time, and judge whether the raw materials are mixed evenly and whether there is any clumping or accumulation.

[0027] This utility model also provides a specific structure of the reciprocating mechanism 3: the reciprocating mechanism 3 includes a support plate 301 fixed on the outer wall of the mixing tank 1, and a connecting shell 302 with an open surface is provided on the support plate 301. A motor 303A is installed on the inner bottom wall of the connecting shell 302, and a reciprocating screw 304 is installed on the transmission shaft of the motor 303A. A rod sleeve 305 is threadedly connected to the outer wall of the reciprocating screw 304. Guide rails 306 for sliding slider 307 are fixedly connected to both sides of the connecting shell 302. A connecting plate 308 is fixedly connected between the slider 307 and the rod sleeve 305, and a vertical rod 309 is fixedly connected to the top of the connecting plate 308. A through groove 310 for the vertical rod 309 to pass through is opened at the top of the connecting shell 302. An mounting plate 311 is fixedly connected to the side end of the lifting platform 2, and the head of the vertical rod 309 is connected to the bottom of the mounting plate 311.

[0028] When the reciprocating mechanism 3 is working, the motor 303 starts, and its transmission shaft drives the reciprocating screw 304 to rotate. The reciprocating screw 304 drives the sleeve 305 to move up and down. The sleeve 305 drives the slider 307 to move up and down linearly along the guide rail 306 through the connecting plate 308, so as to maintain the vertical linear movement of the sleeve 305 and the connecting plate 308. This causes the connecting plate 308 to drive the vertical rod 309 to make vertical reciprocating motion in the through groove 310 at the top of the connecting shell 302. The vertical rod 309 is connected to the mounting plate 311, and finally transmits the motion to the lifting platform 2, driving the lifting platform 2 to make small-amplitude lifting and lowering movements along the vertical direction of the mixing tank 1, thereby achieving the purpose of driving the stirring paddle 4 and the feeding component 5 to move up and down.

[0029] The inner top wall of the connecting shell 302 is rotatably connected to the reciprocating screw 304 via a bearing 312. The bearing 312 provides stable axial and radial support for the reciprocating screw 304, preventing it from shifting or shaking when rotating at high speed or under stress. This ensures the accuracy of the linear reciprocating motion of the sleeve 305 along the axial direction of the reciprocating screw 304, thereby ensuring the smoothness and reliability of the lifting platform 2's lifting motion. Furthermore, the mounting plate 311 and the vertical rod 309 are detachably connected. During equipment maintenance and repair, if the reciprocating mechanism 3 or the lifting platform 2 malfunctions, the mounting plate 311 and the vertical rod 309 can be quickly separated, allowing the lifting platform 2 and its connected structures to be disassembled from the mixing device for repair or replacement. This significantly shortens maintenance time and also facilitates cleaning of the stirring paddle 4 connected to the lifting platform 2.

[0030] The following is the specific detachable structure between the mounting plate 311 and the vertical rod 309: The bottom end of the mounting plate 311 is fixedly connected to a frame-shaped slot 6, the top end of the vertical rod 309 is fixedly connected to a connecting block 7 that can be inserted into the frame-shaped slot 6, the top end of the connecting block 7 is fixedly connected to multiple screws 8, the mounting plate 311 is provided with through holes 9 for the screws 8 to pass through, and nuts 10 are threaded onto the outer side wall of the screws 8.

[0031] During installation, align the frame-shaped slot 6 on the mounting plate 311 with the connecting block 7 at the top of the vertical rod 309, and then insert it. After insertion, the screw 8 on the connecting block 7 will pass through the through hole 9 on the mounting plate 311. Then, rotate the nut 10 clockwise to install the nut 10 on the screw 8. The nut 10 moves downward along the screw 8 and slowly abuts against the top of the mounting plate 311, thus completing the fixation between the mounting plate 311 and the vertical rod 309, and completing the installation of the lifting platform 2 and its connected structures. This method of positioning first using the frame-shaped slot 6 and the connecting block 7 and then fixing ensures that the screw 8 and the through hole 9 are properly aligned. It can quickly and accurately align without repeated adjustments, greatly reducing installation time and operational difficulty. In addition, the positioning structure plays a temporary fixing role before the nut 10 is fixed, preventing the components from shifting during installation and ensuring the smooth progress of the fixing process. Ultimately, it achieves a stable and reliable connection between the mounting plate 311 and the vertical rod 309, enhancing the reliability and stability of the entire reciprocating mechanism 3. Similarly, during disassembly, the nut 10 is removed first, and the frame-shaped slot seat 6 is pulled off the connecting block 7 to separate the mounting plate 311 and the vertical rod 309, thereby removing the lifting platform 2 and its connected structures from the mixing device.
