Description

Technical Field

[0001] This utility model relates to the field of plastic particle cooling technology, specifically to a cooling device for shaping plastic particles. Background Technology

[0002] Currently, plastic strips are manually stretched and initially cooled in water before being pulled out of the water. Because plastic granules are fragile when cut at low temperatures, the strip temperature is generally not too low to ensure that the plastic granules are not damaged during cutting. The strips are then directly sheared into plastic particles by a shearing device and packaged without further cooling. At this point, the plastic particles are still relatively hot, indicating insufficient cooling. This can lead to adhesion in subsequent processes, and shearing debris or dust is still generated during the shearing process. If not removed, this can affect product quality. Summary of the Invention

[0003] I. Technical problems to be solved

[0004] The technical problem this invention aims to solve is insufficient cooling, which may lead to sticking, and the shearing process may generate shear debris or shear dust, affecting product quality.

[0005] II. Technical Solution

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a cooling device for shaping plastic particles, including a cooling shell 1, a feeding pipe 2 connected to one side of the bottom end of the cooling shell 1, a discharging pipe 3 connected to one side of the top end of the cooling shell 1, a feeding tray 4 inside the cooling shell 1, one end of the feeding tray 4 communicating with the feeding pipe 2 and the other end communicating with the discharging pipe 3, a driving component connected to the cooling shell 1 that can drive the material to be discharged from the discharging pipe 3 along the feeding tray 4; a filter cylinder 5 is provided at the center of the cooling shell 1, the filter cylinder 5 is provided with a plurality of filter holes 6 arranged in a circumferential ring, the top end of the filter cylinder 5 is connected to the top wall of the cooling shell 1, the bottom end of the filter cylinder 5 is connected to the bottom wall of the cooling shell 1, the outer wall of the filter cylinder 5 is connected to the inner side wall of the feeding tray 4, a ventilation mechanism that can communicate with the outside is provided inside the filter cylinder 5, the ventilation mechanism drives the airflow from outside the cooling shell 1 through the feeding tray 4 into the filter cylinder 5 and then discharges, a dust discharge pipe 7 is connected to the cooling shell 1 below the filter cylinder 5.

[0007] Furthermore, the driving component includes a vibration motor 11 connected to the cooling shell 1. The vibration motor 11 can drive the material on the feeding tray 4 to move upward along the direction of the feeding tray 4, which facilitates the movement of the material along the feeding tray. At the same time, it can also vibrate and flatten the material on the feeding tray, which facilitates the uniform distribution of the material and improves the cooling uniformity.

[0008] Furthermore, the feeding tray has a spiral structure and is evenly distributed with a number of sieve holes. The diameter of the sieve holes is smaller than the diameter of the plastic particles, which improves the passage of cold air between the feeding trays, thereby improving cooling efficiency and also facilitating the introduction of dust from the upper layer to the bottom of the feeding tray.

[0009] Furthermore, a plurality of damping rods are circumferentially connected to the bottom end of the cooling shell, and a base is connected to the other end of the damping rods. A spring is connected between the base and the cooling shell, and the spring is sleeved on the outside of the damping rods. The combination of the damping rods, the base and the spring helps to reduce the impact of the vibration motor on the base and the components connected to the base.

[0010] Furthermore, the filter holes are arranged tangentially through the side wall of the filter cartridge, allowing dust-laden air to swirl downwards along the inner wall of the filter cartridge, thus aiding in dust removal in conjunction with the connecting cylinder.

[0011] Furthermore, a conical shell structure is provided between the filter cartridge and the dust discharge pipe. The conical shell structure of the connecting cylinder facilitates the smooth discharge of dust through the dust discharge pipe, avoiding dust accumulation dead corners.

[0012] Furthermore, the ventilation mechanism includes an air inlet pipe 8 connected to one side of the top of the cooling shell 1. An exhaust pipe 9 extending out of the cooling shell 1 is connected to the middle of the cooling shell 1. The exhaust pipe 9 is located inside the filter cartridge 5 and is coaxially arranged with the filter cartridge 5. The other end of the exhaust pipe 9 extends to the bottom of the filter cartridge 5. An exhaust fan 10 is provided inside the exhaust pipe 9. Through the ventilation components and the arrangement of the filter holes, the dust-laden airflow enters the filter cartridge 5 tangentially from outside the cooling shell 1 through the feeding tray 4, thereby facilitating the spiral sinking of impurities in the airflow and their discharge through the dust exhaust pipe, while the clean airflow is discharged through the exhaust pipe.

[0013] III. Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] The drive component facilitates the feeding of materials onto the feeding tray, while the ventilation component facilitates the airflow from outside the cooling shell 1 through the feeding tray 4 into the filter cartridge 5 and then out, thereby facilitating the cooling of the materials on the feeding tray. At the same time, the filter holes on the filter cartridge facilitate the entrainment of impurities in the materials during the ventilation process and guide them into the filter cartridge for further dust removal, which is then discharged through the dust exhaust pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combined with appendix Figure 1 , Figure 2 , Figure 3 and Figure 4 A cooling device for shaping plastic particles includes a cooling shell 1. A feed pipe 2 is connected to one side of the bottom of the cooling shell 1, and a discharge pipe 3 is connected to one side of the top of the cooling shell 1. A feeding tray 4 is provided inside the cooling shell 1. The feeding tray 4 has a spiral structure and is evenly distributed with a plurality of sieve holes 12. The diameter of the sieve holes 12 is smaller than the diameter of the plastic particles. One end of the feeding tray 4 is connected to the feed pipe 2, and the other end is connected to the discharge pipe 3. A drive mechanism is connected to the cooling shell 1 to drive the material along the feeding tray 4 and out through the discharge pipe 3. In specific implementation, based on the principle of a spiral vibrating elevator, the drive component may include a vibration motor 11 connected to the cooling shell 1, which can drive the material on the feeding tray 4 to move upwards along the direction of the feeding tray 4; or in specific implementation, the outer side of the feeding tray 4 is not connected to the cooling shell 1, and the filter cartridge 5 is rotatably connected to the cooling shell 1. The drive component can achieve the purpose of feeding by connecting a rotary motor to the cooling shell 1, and the rotary motor drives the filter cartridge 5 to rotate the feeding tray 4 through a gear set.

[0024] The combination of the feeding tray and the drive component in the above structure facilitates the feeding of materials upward along the feeding tray 4. The vibration motor 11 not only ensures that the materials are fed upward along the feeding tray 4, but also vibrates and flattens the materials on the feeding tray 4, which facilitates uniform material distribution and improves cooling uniformity.

[0025] A filter cylinder 5 is connected to the middle of the cooling shell 1. The filter cylinder 5 has a plurality of filter holes 6 arranged in a circumferential annular array. The filter holes 6 are arranged tangentially through the side wall of the filter cylinder 5. The top end of the filter cylinder 5 is connected to the top wall of the cooling shell 1, and the bottom end of the filter cylinder 5 is connected to the bottom wall of the cooling shell 1. The outer wall of the filter cylinder 5 is connected to the inner side wall of the feeding tray 4. A ventilation mechanism is provided inside the filter cylinder 5, allowing communication with the outside. This ventilation mechanism drives airflow from outside the cooling shell 1, through the feeding tray 4, into the filter cylinder 5, and then out. The ventilation mechanism includes an air inlet pipe 8 connected to one side of the top of the cooling shell 1. An exhaust pipe 9 extending out of the cooling shell 1 is connected to the middle of the cooling shell 1. The exhaust pipe 9 is located inside the filter cartridge 5 and is coaxially arranged with the filter cartridge 5. The other end of the exhaust pipe 9 extends to the bottom of the filter cartridge 5. An exhaust fan 10 is provided inside the exhaust pipe 9. A dust discharge pipe 7 is connected to the cooling shell 1 below the filter cartridge 5. A valve is connected to the dust discharge pipe. A conical shell structure connecting cylinder 15 is connected between the filter cartridge 5 and the dust discharge pipe 7.

[0026] The exhaust fan in the above structure creates a negative pressure inside the filter cartridge. At this time, the bottom of the dust exhaust pipe is closed, and the negative pressure drives the air inlet pipe to introduce cold air between the filter cartridge and the cooling shell. Due to the setting of the feeding tray, most of the cold air is transmitted along the direction of the feeding tray, which facilitates the cooling of the plastic particles on the feeding tray. Some of the cooling air carries dust and is introduced into the filter cartridge, which facilitates the dust removal operation of the plastic particles.

[0027] Example 2

[0028] Based on Example 1, and in conjunction with Appendix Figure 3 The cooling shell 1 is circumferentially connected to a plurality of damping rods 13, and the other end of the damping rods is connected to a base. A spring 14 is connected between the base and the cooling shell 1, and the spring 14 is sleeved on the outside of the damping rods 13.

[0029] The combination of damping rod 13, base and spring 14 in the above structure helps to reduce the impact of the vibration motor on the base and the components connected to the base.

[0030] The specific usage method is as follows:

[0031] By starting the vibration motor, the feeding tray 4, driven by the vibration motor, transfers plastic particles from one end of the feed pipe 2 to one end of the discharge pipe 3. By starting the exhaust fan 10, the exhaust fan 10 drives external cold air to be introduced from one side of the air inlet pipe 8 between the cooling shell 1 and the filter cartridge 5. The diameter of the sieve hole 12 is smaller than the diameter of the plastic particles, which improves the passage of cold air between the feeding trays 4, which facilitates the improvement of cooling efficiency and also facilitates the introduction of dust from the upper layer to the bottom of the feeding tray 4. The vibrating plastic particles are constantly thrown up and down, which facilitates the flat distribution of plastic particles and also facilitates a larger contact area between the plastic particles and the cold air, so as to improve the cooling efficiency. Meanwhile, the debris and dust mixed in the plastic particles are driven by the cold air to be introduced into the filter cartridge 5 through the filter hole 6. The filter hole 6 is set along the tangential direction of the filter cartridge 5 through the side wall of the filter cartridge 5, so that the dust-laden air can swirl downward along the inner wall of the filter cartridge 5. With the setting of the conical shell connecting cylinder 15, the dust can be discharged through the dust discharge pipe 7, and the clean gas after dust removal is discharged through the exhaust pipe 9.
