Description

Technical Field

[0001] This utility model relates to the field of PE film production technology, and in particular to a cooling device. Background Technology

[0002] After extrusion molding, PE film needs to be cooled. Most existing cooling methods use cooling rings, which are installed at the outlet of the extruder. The extruded PE film passes through the cooling ring and is then cooled by air blown out from the air outlets around the cooling ring.

[0003] However, the existing cooling ring's air outlet structure is relatively simple and does not integrate the airflow, resulting in the airflow being relatively dispersed after it is blown out. This leads to a short distance of airflow traveling in the direction of travel, making it impossible to cool the ends of the PE film when the extruded length is long, resulting in low cooling efficiency and inconvenience in use. Therefore, we propose a cooling device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies mentioned in the background section by proposing a cooling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling device includes a cooling ring and multiple sets of air outlets installed around the ends of the cooling ring. A mounting base is placed inside the air outlet, and a rotating fan blade is movably installed inside the mounting base. The rotating fan blade can rotate inside the mounting base. Mounting blocks are provided around the outer wall of the mounting base, and mounting slots are opened around the inner wall of the air outlet. The mounting blocks extend into the interior of the mounting slots.

[0007] This allows the airflow to pass through the air outlet, causing the fan blades to rotate. This, in turn, drives the airflow, integrating the airflow and allowing it to travel a greater distance, thus improving the cooling effect on the PE film.

[0008] Preferably, the outer wall of the air outlet is provided with a rotating groove at the bottom of the mounting slot, and a rotating rod is provided inside the rotating groove, the rotating rod being in contact with the side wall of the mounting block;

[0009] After the mounting block is embedded into the mounting slot, the rotating rod can limit the mounting block to prevent it from falling out of the mounting slot, thus improving the stability of the mounting base and rotating fan blades after installation.

[0010] Preferably, the side wall of the mounting block is provided with a positioning slot, and the rotating rod can extend into the interior of the positioning slot;

[0011] This allows the rotating rod to be embedded inside the positioning slot, further preventing the mounting block from detaching from the mounting slot and improving the stability of the mounting base and rotating fan blades after installation.

[0012] Preferably, a rotating ring is sleeved around the air outlet, and the inner sidewall of the rotating ring is fixedly connected to the end of the rotating rod.

[0013] The rotating ring can be rotated to drive the rotating rod to rotate, making it easier for the rotating rod to be inserted into or removed from the positioning slot.

[0014] Preferably, the inner wall of the rotating slot is provided with a support spring, and the support spring is located on the side of the rotating rod away from the mounting block;

[0015] The support spring can support the rotating rod, thereby improving the stability of the rotating rod inside the positioning slot and preventing the rotating rod from directly leaving the positioning slot.

[0016] Preferably, the end of the support spring is provided with a movable block, and the movable block is in contact with the outer wall of the rotating rod;

[0017] The support spring can push the moving block to move the rotating rod, thereby increasing the contact area between the moving block and the rotating rod and improving the stability of the rotating rod after it is placed.

[0018] Preferably, the upper and lower ends of the movable block are in contact with the upper and lower ends of the inner wall of the rotating slot, the side wall of the movable block is arc-shaped, and the arc-shaped surface is adapted to the outer wall of the rotating rod.

[0019] This can improve the stability of the moving block, which in turn improves the stability of the rotating rod.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This utility model enables the wind to drive the rotating fan blades to rotate after passing through the air outlet, so that the rotating fan blades drive the wind to rotate and form a vortex, thereby completing the integration of wind power, so that the wind can be blown a farther distance, and thus better cool the PE film.

[0022] 2. This utility model can rotate the rotating ring to drive the rotating rod to rotate, thereby causing the rotating rod to disengage from the positioning slot. At this time, the mounting base and the rotating fan blade can be disassembled to facilitate cleaning of the rotating fan blade. After cleaning, the mounting block is re-embedded into the mounting slot. At this time, the support spring drives the rotating rod to rotate through the moving block, so that the rotating rod is re-embedded into the positioning slot for limiting and preventing the mounting base and the rotating fan blade from disengaging.

[0028] 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.

[0029] Reference Figure 1-4 The cooling device shown has air outlets 2 around the top of the cooling ring 1. A mounting base 3 is placed inside the air outlet 2, and a rotating fan blade 4 is rotatably mounted inside the mounting base 3. Mounting blocks 6 are fixedly mounted on the outer walls of the mounting base 3. The inner wall of the air outlet 2 has multiple sets of mounting slots 5, allowing the mounting blocks 6 to extend into the mounting slots 5. A rotating ring 9 is sleeved on the outside of the air outlet 2. A rotating rod 10 is fixedly mounted on the inner side wall of the rotating ring 9. A rotating slot 8 is formed on the outer wall of the air outlet 2 below the mounting slots 5, allowing the rotating rod 10 to extend into the rotating slot 8. The side wall of the mounting block 6 has a positioning slot 7, which allows the rotating rod 10 to be inserted into the positioning slot 7 after rotation for limiting and preventing the mounting slot 5 from dislodging from the mounting block 6.

[0030] For a detailed description of the support spring 11 in this embodiment, please refer to [link / reference]. Figure 3 A support spring 11 is fixedly installed at one end of the inner wall of the rotating slot 8, and a moving block 12 is fixedly installed at the other end of the support spring 11. The end of the moving block 12 is arc-shaped, and the arc surface of the moving block 12 is adapted to the rotating rod 10, so that the rotating rod 10 can be pushed to better embed into the interior of the positioning slot 7.

[0031] Working principle: When the air passes through the inside of the air outlet 2, the fan blades 4 can rotate, which in turn causes the airflow to rotate, making the airflow more concentrated and the airflow travels a longer distance, which can better cool the PE film.

[0032] Simultaneously, the rotating ring 9 can be rotated, causing the rotating rod 10 to rotate and disengage from the positioning slot 7. At this point, personnel can directly pull the rotating fan blade 4 to move the mounting base 3, causing the mounting base 3 to disengage the mounting block 6 from the mounting slot 5, thus completing the disassembly of the rotating fan blade 4 for easy cleaning. After installation, the rotating ring 9 is released, allowing the support spring 11 to push the rotating rod 10 through the moving block 12, thus limiting the position of the rotating rod 10 embedded in the positioning slot 7. The operation is simple and convenient.
