Description

Technical Field

[0001] The utility model relates to the technical field of mixers, and specifically, to a plastic particle mixer. Background Art

[0002] Mixers are used for processes such as mixing, stirring, and coloring of materials in industries such as plastics, rubber, daily chemical industry, and food. They are special equipment for producing plastic sheets, pipes, profiles, and degradable plastics. Generally, when processing plastic particles, a mixer is required to mix them.

[0003] After retrieval, a Chinese patent with the publication number of CN214447587U discloses a plastic particle mixer, which includes a mixer body. The mixer body includes a cylinder body. The top of the cylinder body is connected to a flange by welding. The top of the flange is welded to a cover plate. Above the cover plate, there is a motor group. The bottom of the motor group is connected to a rotating shaft. The rotating shaft extends downward through the cover plate and the flange and then reaches the bottom of the cylinder body. A stirring member is provided on the rotating shaft. In this plastic particle mixer, by setting the cylinder body as a conical body and connecting a discharge pipe at its bottom opening, it is convenient for discharging. By adding transverse channel steel and longitudinal channel steel for splicing, the vibration of the motor during operation on the cover plate, the flange, and the entire cylinder body can be greatly reduced, effectively extending the service life of the entire device.

[0004] There are some drawbacks in the existing devices during use. For example, when stirring plastic particles, generally, a motor drives a spiral blade fixed on a rotating rod to stir the plastic particles. During the stirring process, the stirring structure of the existing device is too single, and it can only stir the plastic particles at a fixed position. This kind of stirring makes the plastic particles not be fully stirred and not be fully mixed. Therefore, a plastic particle mixer is designed to meet people's needs. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a plastic particle mixer to solve the problem that during the stirring process, some smaller plastic particles will adhere to the inner wall of the container and cannot be cleaned and stirred.

A plurality of support frames are annularly arranged at the lower bottom end of the housing. A rubber ring is fixedly installed on the upper end surface of the housing. A cover plate is fixedly installed on the upper end surface of the rubber ring. A stirring mechanism for stirring plastic particles is arranged inside the housing, and a lifting mechanism for assisting in stirring plastic particles is arranged inside the housing.

[0007] As a preference of the above technical solution, the stirring mechanism includes a plurality of fixed columns. The lower end surfaces of the plurality of fixed columns are fixedly connected to the upper end surface of the cover plate. A support plate is fixedly installed on the upper end surface of the fixed column. A driving motor is fixedly installed on the lower end surface of the support plate. A bidirectional lead screw is fixedly installed at the power output end of the driving motor. A lifting plate is sleeved on the threaded portion of the bidirectional lead screw.

[0008] As a preference of the above technical solution, the lifting mechanism includes a bidirectional lead screw vertically penetrating through the fixed frame. The bidirectional lead screw is rotatably connected to the fixed frame. Two first transmission wheels are fixedly connected to the side wall of the bidirectional lead screw. A first transmission belt is sleeved on the side walls of the two first transmission wheels. The other end of the first transmission belt is sleeved with a second transmission wheel. The second transmission wheel is rotatably connected to the outer shell.

[0009] As a preference of the above technical solution, a spline shaft is fixedly installed on the end face of the second transmission wheel. A spline sleeve is fixedly installed on the side wall of the spline shaft. A spiral blade is fixedly installed on the lower side wall of the spline sleeve. A bearing is fixedly installed on the upper side wall of the spline sleeve. The outer side wall of the bearing is fixedly connected to the lifting plate. A plurality of bellows protective covers are fixedly connected to the end face of the lifting plate. The other ends of the plurality of bellows protective covers are fixedly connected to the fixed frame

[0010] As a preference of the above technical solution, a discharge pipe is vertically penetrated and installed at the bottom of the outer shell. The outer side wall of the discharge pipe is fixedly connected to the outer shell. A valve is rotatably installed on the side wall of the discharge pipe.

During the lifting process, the spiral blade will also rotate to stir the plastic particles, making full use of the internal space of the container, breaking the traditional form of stirring plastic particles at a fixed position, enabling the plastic particles to be fully stirred and fully mixed together, greatly improving the mixing efficiency of the device.

In the specific use process, the raw materials are added into the outer shell 1 through the feed pipe 31. Two feed pipes 31 are opened on the top of the cover plate 7, which can add materials simultaneously to improve the feeding rate. Through the design of arranging a plurality of support frames 2 at the bottom of the outer shell 1, the device is supported, the stability of the device is improved, and the device runs more smoothly. Through the design of fixedly connecting the rubber ring 6 to the upper end surface of the outer shell 1, the vibration of the driving motor 43 on the cover plate 7 and the outer shell 1 during operation can be greatly reduced, and the service life of the entire equipment can be effectively extended.

[0020] As an implementation manner in this embodiment, as Figure 1 and Figure 2 shown, the stirring mechanism 4 includes a plurality of fixed columns 41. The lower end surfaces of the plurality of fixed columns 41 are fixedly connected to the upper end surface of the cover plate 7. A support plate 42 is fixedly installed on the upper end surface of the fixed column 41. A driving motor 43 is fixedly installed on the lower end surface of the support plate 42. A bi-directional lead screw 44 is fixedly installed at the power output end of the driving motor 43. A lifting plate 445 is sleeved on the threaded part of the bi-directional lead screw 44. In the specific use process, the motor is started, the power output end of the motor rotates, and the power output end of the motor rotates to drive the bi-directional lead screw 44 to rotate. During the rotation of the bi-directional lead screw 44, the lifting plate 445 sleeved on its side wall moves up and down.

[0021] As an implementation manner in this embodiment, as Figure 3As shown in the figure, the lifting mechanism includes a bidirectional lead screw 44 vertically penetrating through the fixed frame 441. The bidirectional lead screw 44 is rotatably connected to the fixed frame 441. Two first conveyor wheels 442 are fixedly connected to the side wall of the bidirectional lead screw 44. A first conveyor belt 444 is sleeved on the side walls of the two first conveyor wheels 442. The other end of the first conveyor belt 444 is sleeved with a second conveyor wheel 443. The second conveyor wheel 443 is rotatably connected to the housing 1. A spline shaft 448 is fixedly installed on the end face of the second conveyor wheel 443. A spline sleeve 447 is fixedly installed on the side wall of the spline shaft 448. A spiral blade 449 is fixedly installed on the lower side wall of the spline sleeve 447. A bearing 446 is fixedly installed on the upper side wall of the spline sleeve 447. The outer side wall of the bearing 446 is fixedly connected to the lifting plate 445. A plurality of bellows protective covers 4411 are fixedly connected to the end face of the lifting plate 445. The other ends of the plurality of bellows protective covers 4411 are fixedly connected to the fixed frame 441. In the specific use process, when the bidirectional lead screw 44 rotates, it drives the lifting plate 445 to move up and down, and at the same time drives the two first conveyor wheels 442 to rotate. When the two first conveyor wheels 442 rotate, they drive the second tooth conveyor wheel to rotate through the connection of the conveyor belt. When the second conveyor wheel 443 rotates, it drives the spline shaft 448 to rotate. When the spline shaft 448 rotates, it drives the spline sleeve 447 to rotate. When the spline sleeve 447 rotates, it drives the spiral blade 449 to rotate. Through the connection of the bearing 446 to the spline sleeve 447 and the design of connecting the lifting plate 445 to the bearing 446, the spiral blade 449 can move up and down while rotating.

[0022] As an implementation method in this embodiment, as Figure 1 shown, a discharge pipe 5 is vertically penetrated and installed at the bottom of the housing 1. The outer side wall of the discharge pipe 5 is fixedly connected to the housing 1. A valve 51 is rotatably installed on the side wall of the discharge pipe 5. In the specific use process, through the design of the material outlet at the bottom connection of the housing 1, it is convenient to discharge materials. When the particle plastics are mixed completely, by rotating the valve 51, the mixed materials can be taken out.

[0023] As an implementation method in this embodiment, as Figure 1 shown, jacks 3 are symmetrically opened on the upper end face of the cover plate 7. The two jacks 3 penetrate through the cover plate 7. A feed pipe 31 is fixedly installed in the two jacks 3. In the specific use process, by setting a plurality of feeding ports at the top, materials can be added simultaneously, improving the feeding rate.

[0024] Working principle: The raw materials are added into the interior of the outer shell 1 through the feeding pipe 31. Two feeding pipes 31 are provided at the top of the cover plate 7. Start the motor, and the power output end of the motor rotates. The rotation of the power output end of the motor drives the bidirectional lead screw 44 to rotate. When the bidirectional lead screw 44 rotates, it drives the spiral blade 449 fixed on its side to rotate, so as to stir and mix the plastic particles. When the bidirectional lead screw 44 rotates, during the rotation process, it drives the lifting plate 445 to move up and down, and also drives two first transmission wheels 442 to rotate. When the two first transmission wheels 442 rotate, they drive the second toothed transmission wheel to rotate through the connection of the conveyor belt. When the second transmission wheel 443 rotates, it drives the spline shaft 448 to rotate. When the spline shaft 448 rotates, it drives the spline sleeve 447 to rotate. When the spline sleeve 447 rotates, it drives the spiral blade 449 to rotate. The spline sleeve 447 is connected by a bearing 446, and the lifting plate 445 is connected to the bearing 446. This design enables the spiral blade 449 to move up and down while rotating. When the mixing of the particle plastics is completed, the mixed materials are discharged by rotating the valve 51.
