Description

Technical Field

[0001] The utility model relates to the field of air cooling devices, in particular to an air cooling device for extruding biodegradable resin. Background Art

[0002] After extrusion molding, the temperature of biodegradable resin is often high, and it is necessary to quickly reduce its temperature through an air cooling device to stabilize the physical and chemical properties of the resin and prevent deformation, aging or performance degradation caused by high temperature. At the same time, the air cooling device can shorten the cooling time of the resin, speed up the production process, and thus improve overall production efficiency.

[0003] However, the fans in existing air-cooling devices used for post-extrusion biodegradable resins typically operate in a fixed position, making it difficult for workers to adjust the cooling effect. Furthermore, because the airflow directly from the fans is too fast, this high-intensity cooling method can sometimes cause unnecessary damage to the surface of the biodegradable resin material, affecting its final quality.

[0004] Therefore, in order to address the situation where the fan in the above-mentioned air cooling device cannot be adjusted and the air flow speed blown directly by the fan is too fast, an air cooling device after extrusion of biodegradable resin can be designed. Through a threaded transmission structure and a belt transmission structure, the height of the fan can be adjusted while the wind speed of the air flow blown out by the fan can be slowed down. Utility Model Content

[0005] In order to overcome the problem that the fan in the air cooling device cannot be adjusted and the air flow speed directly blown out by the fan is too fast.

[0006] The technical solution of the utility model is: an air cooling device after extrusion of biodegradable resin, including a conveyor belt, support legs, a base plate, a door frame, an adjustment structure, an outer shell and a through slot; the lower end of the conveyor belt is fixedly connected with four support legs for support, the base plate is located at the lower end of the conveyor belt and the upper end of the base plate is fixedly connected with the door frame, the door frame consists of a crossbeam and two columns, the two columns are respectively located on the left and right sides of the conveyor belt, the adjustment structure is installed at the lower end of the door frame, a lifting plate is provided in the adjustment structure, the outer shell is fixedly connected to the lower end of the lifting plate, and a through slot is opened through the center of the upper end of the lifting plate.

[0007] Preferably, the conveyor belt is responsible for carrying and transmitting the biodegradable resin material extruded from the extruder, which ensures that the material can be continuously and smoothly moved to the air-cooling area for subsequent cooling treatment. The base plate provides an installation basis for other components, such as the gantry and the rotating support seat. The gantry consists of a crossbeam and two columns to form a stable frame structure. It is a component that supports the outer shell and the adjustment structure. The adjustment structure is used to adjust the height of the outer shell, so as to control the air-cooling effect. A fan is installed inside the outer shell for air-cooling the resin material on the conveyor belt. The through groove provides installation space for the dust cover.

[0008] Preferably, two rotating support seats are symmetrically fixedly connected to the upper end of the base plate, and a rotating motor is installed at the upper end of the door frame. The function of the rotating support seat is to serve as the rotating fulcrum of the No. 1 threaded rod and the No. 2 threaded rod, ensuring that the threaded rod can rotate smoothly without deviation. The rotating support seat is made of solid metal material and is designed with a bearing mechanism inside to reduce friction and wear during the rotation of the threaded rod. The rotating motor is the power source for driving the No. 1 threaded rod to rotate, and the No. 1 threaded rod can be driven to rotate through the output shaft of the rotating motor.

[0009] Preferably, the lower end of the No. 1 threaded rod is rotatably connected to the rotating support seat on the left side, and the upper end of the No. 1 threaded rod is equipped with a coupling and is connected to the output shaft of the rotating motor through the coupling. The coupling is connected between the output shaft of the rotating motor and the No. 1 threaded rod, and is used to transmit the power of the rotating motor to the No. 1 threaded rod. The No. 1 threaded rod drives the driving wheel to rotate by rotating.

[0010] Preferably, the adjustment structure includes a No. 2 threaded rod and a lifting plate; the lower end of the No. 2 threaded rod is rotatably connected to the rotating support seat on the right, and the upper end of the No. 2 threaded rod extends upward to the upper end of the door frame. An internal thread that is compatible with the external thread of the No. 1 threaded rod and the No. 2 threaded rod is provided in the lifting plate. The No. 1 threaded rod and the No. 2 threaded rod are threadedly connected in the lifting plate. When the No. 1 threaded rod and the No. 2 threaded rod rotate at the same time, the lifting plate can be pushed up and down by the action between the threads, thereby adjusting the height of the outer shell, and then adjusting the distance between the fan and the biodegradable resin material, thereby achieving the effect of controlling the air cooling effect.

[0011] Preferably, the upper outer wall of the No. 1 threaded rod is fixedly connected to a driving wheel, and the upper outer wall of the No. 2 threaded rod is fixedly connected to a driven wheel. The driving wheel and the driven wheel rotate together and are connected by a belt. The driving wheel, the driven wheel and the belt constitute a belt transmission structure, which is connected to the upper ends of the No. 1 threaded rod and the No. 2 threaded rod to achieve synchronous rotation of the two. When the rotating motor drives the No. 1 threaded rod to rotate, the No. 2 threaded rod can be driven to rotate synchronously through the belt transmission structure. The belt transmission mechanism has the advantages of simple structure, smooth transmission and low noise.

[0012] Preferably, a dust cover is fixedly connected to the through slot, a fan with a built-in power supply is installed in the outer shell and the fan is located at the lower end of the dust cover. The dust cover is a component fixed in the through slot, which is used to prevent external dust, debris, etc. from entering the fan area and protect the fan from pollution and damage. The fan rotates using the power provided by the built-in power supply to generate airflow to perform air cooling operation on the biodegradable resin material on the conveyor belt.

[0013] Preferably, the inner walls of the front and rear ends of the shell are fixedly connected with an inverted V-shaped speed reducer, the lower end of the shell is fixedly connected with a funnel-shaped wind collecting frame, the air outlet of the wind collecting frame is fixedly connected with a partition, and the surface of the partition is penetrated with air outlet holes. The inverted V-shaped speed reducer is used to slow down the speed of the airflow, thereby avoiding damage to the biodegradable resin material caused by excessive wind force. The funnel-shaped wind collecting frame is used to gather and guide the airflow generated by the fan, so that the airflow can be discharged to the outside of the shell more concentratedly through the air outlet. The partition is a component fixed at the air outlet of the wind collecting frame, which is used to provide an installation basis for the air outlet. At the same time, the air outlet allows the airflow to blow evenly to the biodegradable resin material, thereby improving the air cooling effect.

[0027] See also Figure 2 and Figure 6In this embodiment, a dust cover 16 is fixedly connected to the through slot 6, a fan 17 with a built-in power supply is installed in the shell 5 and the fan 17 is located at the lower end of the dust cover 16, and an inverted V-shaped deceleration plate 18 is fixedly connected to the inner walls of the front and rear ends of the shell 5. A funnel-shaped wind gathering frame 19 is fixedly connected to the lower end of the shell 5, and a partition 20 is fixedly connected to the air outlet of the wind gathering frame 19. An air outlet hole 21 is opened on the surface of the partition 20. The dust cover 16 is a component fixed in the through slot 6, which is used to prevent external dust, debris, etc. from entering the fan 17 area, protecting the fan 17 from pollution and damage. The fan 17 uses a built-in power supply to The electric power supplied is used to rotate, thereby generating airflow to cool the biodegradable resin material on the conveyor belt 1.

With the help of the belt 15, the No. 2 threaded rod 11 also rotated. The interaction between the threads allowed the lifting plate 12 to move vertically, thereby adjusting the height of the fan 17 in the housing 5.

Then, the airflow is slowly blown out from the air outlet under the guidance of the wind gathering frame 19 to perform air cooling on the biodegradable resin material.
