Description

Technical Field

[0001] The utility model relates to the field of plastic particles, in particular to a cooling device for processing plastic particles. Background Art

[0002] Plastic particles are the common name for plastic particles. They are the raw materials for storing, transporting and processing plastics in the form of semi-finished products. Plastic particles have a wide range of applications. In daily life, recycled particles can be used to make various plastic bags, buckets, basins, toys, furniture, stationery and other daily necessities and various plastic products. The processing and manufacturing of plastic particles requires multiple processes, including heating, stirring, cutting and cooling.

[0003] Most of the existing cooling devices for processing plastic particles place the plastic particles in a mixing barrel, and then cool them by passing cold air inward and cooperating with a stirring mechanism. However, in actual use, this cooling device always blows cold air in one direction, which leads to uneven temperature distribution in the mixing barrel, affecting the overall cooling effect. At the same time, the stirring mechanism will throw the internal plastic particles toward the inner wall of the mixing barrel, while the cold air is difficult to blow toward the inner wall of the mixing barrel, which further affects the cooling efficiency and increases the overall cooling cost.

[0004] To sum up, the above-mentioned cooling structure always blows in one direction during use, which causes uneven temperature distribution in the mixing barrel, affecting the overall cooling effect. The stirring mechanism will throw the internal plastic particles toward the inner wall of the mixing barrel, further affecting the cooling efficiency and increasing the overall cooling cost. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a cooling device for plastic particle processing to solve the technical problem that air is always blown in one direction during use, thereby causing uneven temperature distribution in the mixing barrel, and the stirring mechanism will throw the internal plastic particles toward the inner wall of the mixing barrel, thereby further affecting the cooling efficiency and increasing the overall cooling cost.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling device for processing plastic particles, comprising a cylinder, an air supply mechanism is arranged at the bottom of the cylinder, and an arc plate is arranged at the top of the air supply mechanism, and the arc plate is arranged in an inwardly concave manner, and an array of through holes is spread out from the center position to the surrounding areas on the arc plate, a driving assembly is arranged at the top of the cylinder, and a stirring mechanism is connected to the output end of the driving assembly that passes through the cylinder, a spiral flow channel is arranged in the interlayer of the cylinder, and an air inlet is connected to one end of the spiral flow channel, and the air inlet is located at the bottom of the arc plate.

[0007] By adopting the above technical solution, when the air supply mechanism is started, the cold air will be blown to the bottom of the arc plate and diffused to the surroundings. In this process, the cold air is diffused through the through holes on the arc plate and discharged to the plastic particles. Since the diffusion area of ​​the cold air is increased, part of the cold air will be discharged into the spiral flow channel through the air inlet. Under the action of the spiral flow channel, the inner wall of the cylinder is evenly dissipated, and the stirring mechanism is cooperated to accelerate the overall cooling efficiency. In this process, only a single set of air supply mechanism is needed to complete the cooling of the plastic particles, which greatly reduces the overall cooling cost.

[0008] The utility model is further configured that the driving component is a stirring motor, and the stirring motor is used to drive the stirring mechanism at the output end to rotate.

[0009] By adopting the above technical solution, it is convenient for the staff to adjust the rotation speed of the stirring mechanism according to the specific conditions of the plastic particles in the cylinder under the action of the stirring motor, thereby further improving the overall practicality.

[0010] The utility model is further configured that the stirring mechanism includes a stirring rod, transverse stirring blades and longitudinal stirring blades, the outer wall of the stirring rod is evenly provided with a plurality of transverse stirring blades, and longitudinal stirring blades are rotatably provided on the transverse stirring blades.

[0011] By adopting the above technical solution, when the stirring motor starts to drive the stirring rod to rotate, the horizontal stirring blades on its outer wall will also rotate. During the rotation, the plastic particles will impact the longitudinal stirring blades, so that the cooperation between the longitudinal stirring blades and the transverse stirring blades increases the disturbance range in the cylinder, thereby further improving the overall cooling efficiency.

[0012] The utility model is further configured that a feed port, a second exhaust port and a first exhaust port are respectively opened on the cylinder, and one end of the spiral flow channel is connected to the first exhaust port.

[0013] By adopting the above technical solution, the feed port makes it easier for the staff to discharge the plastic particles to be cooled into the cylinder. During the cooling process, the high-temperature air cooled in the cylinder will be discharged from the cylinder through the second exhaust port, and the gas in the spiral flow channel will also be discharged through the first exhaust port.

[0014] The utility model is further configured that the bottom of the cylinder is provided with an opening for air intake of the air supply mechanism.

[0015] By adopting the above technical solution, the setting of the opening makes it easy to draw cold air from the outside and discharge it into the cylinder when the air supply mechanism is started.

[0016] The utility model is further configured that the aperture of the through hole itself is smaller than the diameter of the plastic particles.

[0017] By adopting the above technical solution, plastic particles can be effectively prevented from getting stuck in the through holes during the stirring process, thereby preventing the through holes from being blocked, and further improving the overall cooling stability of the device.

[0018] The utility model is further configured such that a seal is provided between the first exhaust port and the spiral flow channel.

[0019] By adopting the above technical solution, the leakage of the cooled gas and the backflow in the spiral flow channel can be prevented, thereby further improving the overall cooling efficiency of the device.

[0020] The utility model is further configured that the front end of the cylinder is provided with an observation window.

[0021] By adopting the above technical solution, the staff can intuitively observe the cooling process of the plastic particles in the cylinder through the observation window.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with an air supply mechanism at the bottom of the cylinder and an arc-shaped plate at the top. When the air supply mechanism is started, cold air will be blown to the bottom of the arc-shaped plate and diffused to the surroundings. In this process, the cold air is diffused through the through holes in the arc-shaped plate and discharged to the plastic particles. Since the diffusion area of ​​the cold air is increased, the overall cooling effect is improved. At the same time, part of the cold air will be discharged into the spiral flow channel through the air inlet. Under the action of the spiral flow channel, uniform heat dissipation is achieved on the inner wall of the cylinder, and the stirring mechanism is cooperated to accelerate the overall cooling efficiency. In this process, only a single set of air supply mechanism is needed to complete the cooling of the plastic particles, which greatly reduces the overall cooling cost.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] Embodiment 1

[0032] A cooling device for processing plastic particles, such as Figure 1-Figure 3 As shown, it includes a cylinder 1, a stirring mechanism 6, a cooling mechanism and an air supply mechanism 9. The device is placed at a designated position, and then a feed port 5 is provided at the top of the cylinder 1. Under the action of the feed port 5, it is convenient for the staff to discharge the plastic particles to be cooled to the bottom of the cylinder 1. At the same time, an air supply mechanism 9 is provided at the bottom of the cylinder 1, and an arc plate 8 is provided at the top of the air supply mechanism 9, and the arc plate 8 is concavely provided. At the same time, an array of through holes 10 is spread from the center position to the surroundings on the arc plate 8. The staff starts the air supply mechanism 9. , and discharge the external cooling air to the cylinder 1. At this time, the cold air will blow to the bottom of the arc plate 8. Since the center of the arc plate 8 is sealed, the gas will diffuse to the surroundings of the arc plate 8. In this process, the cold air diffuses through the through holes 10 on the arc plate 8 and is discharged to the plastic particles. Since the diffusion area of ​​the cold air is increased, the overall cooling effect is improved, and a second exhaust port 3 is provided at the top of the cylinder 1. The cooled gas will be discharged to the outside of the cylinder 1 through the second exhaust port 3, thereby ensuring the cooling efficiency in the cylinder 1;

[0033] At the same time, a spiral flow channel 7 is arranged in the interlayer of the cylinder 1, and an air inlet 11 is connected to one end of the spiral flow channel 7, and the air inlet 11 is located at the bottom of the arc plate 8. When the gas diffuses at the bottom of the arc plate 8, part of the cold air will enter the spiral flow channel 7 through the air inlet 11. Under the action of the spiral flow channel 7, the inner wall of the cylinder 1 is evenly dissipated, and its cold air is fully utilized. A stirring motor 4 is arranged at the top of the cylinder 1, and the output end of the stirring motor 4 passes through the cylinder 1 and is connected to a stirring mechanism 6. When the spiral flow channel 7 dissipates heat to the inner wall of the cylinder 1, it cooperates with the stirring mechanism 6 to accelerate the overall cooling efficiency. In this process, only a single set of air supply mechanism 9 is required to complete the cooling of the plastic particles, which greatly reduces the overall cooling cost.

[0034] See also Figure 2 The aperture of the through hole 10 is smaller than the diameter of the plastic particles, which effectively prevents the plastic particles from getting stuck in the through hole 10 during the stirring process, thereby preventing the through hole 10 from being blocked, further improving the overall cooling stability of the device, wherein the first exhaust port 2 and the spiral flow channel 7 are sealed to prevent the cooled gas from leaking and flowing back in the spiral flow channel 7, further improving the overall cooling efficiency of the device.

[0035] Embodiment 2

[0036] like Figure 4 A cooling device for plastic particle processing shown in the figure has an overall structure similar to that of the first embodiment, wherein the stirring mechanism 6 includes a stirring rod 13, transverse stirring blades 12 and longitudinal stirring blades 14, and an array of transverse stirring blades 12 are evenly arranged on the outer wall of the stirring rod 13, and longitudinal stirring blades 14 are rotatably arranged on the transverse stirring blades 12. When the stirring motor 4 is started to drive the stirring rod 13 to rotate, the transverse stirring blades 12 on the outer wall will also rotate accordingly. During the rotation, the plastic particles will impact the longitudinal stirring blades 14, so that the cooperation of the longitudinal stirring blades 14 and the transverse stirring blades 12 increases the disturbance range in the cylinder 1, thereby further improving the overall cooling efficiency.

[0037] The working principle of the utility model is as follows: when in use, the plastic particles to be cooled are discharged into the interior of the cylinder 1 through the feed port 5, and then the air supply mechanism 9 at the bottom of the cylinder 1 is started, and the cold air is blown to the bottom of the arc plate 8 under the action of the air supply mechanism 9. Since the arc plate 8 is provided with an array of through holes 10 that diffuse from the center to the surroundings, the diffused cold air is discharged to the plastic particles under the action of the through holes 10, thereby increasing the diffusion area of ​​the cold air in the cylinder 1. At the same time, part of the cold air will enter the spiral flow channel 7 of the cylinder 1 through the air inlet 11, and under the action of the spiral flow channel 7, the cold air surrounds the cylinder 1 and is discharged through the first exhaust port 2, and then cooperates with the stirring mechanism 6 to accelerate the overall cooling efficiency.
