Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to an air cooling and shaping device for extruded bag films. Background Art

[0002] The air cooling and shaping device for extruded bag film is a device used to cool and shape the extruded bag film. It is usually composed of a fan, an air ring, a cooling pipe, etc. During the extrusion process, the molten plastic is extruded through the extruder and enters the air cooling and shaping device. The fan blows air into the air ring to form a high-speed airflow to cool the extruded bag film, thereby improving the quality of the bag film and production efficiency.

[0003] The power source of the currently used air cooling device is set to be a fan. However, given that the wind source itself will inevitably attract dust, causing dust to adhere to the plastic film product. For example, in an actual production environment, the airflow formed when the fan is running may carry dust particles in the surrounding environment, and these dust particles may adhere to the surface of the extruded plastic film with the airflow. Therefore, in order to effectively avoid the situation where dust is retained on the surface of the product over a large area, in this specific situation, a wind-cooled shaping device for extruded bag film is specially proposed.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A wind-cooling shaping device for extruded bag film comprises a blowing pipe 2, two hanging plates 1 are installed on the blowing pipe 2, an air inlet pipe 3 is installed on the blowing pipe 2, and the other end of the air inlet pipe 3 is connected to an air inlet component, such as a fan and other components. The blowing pipe 2 can be hoisted and installed on the top of the wall of a processing workshop by relying on the hanging plate 1. The bag film body 8 is located under the blowing pipe 2 and is moved by means of a roller component in the prior art. The air is blown out through the blowing pipe 2 to realize the wind-cooling shaping operation.

[0022] The blowing pipe 2 is provided with multiple blowing ports 9, and a rotating frame 4 is rotatably provided on the blowing pipe 2 through a limiting mechanism. Multiple intercepting nets 5 are provided on the rotating frame 4 through multiple installation ports, and an installation groove is provided on the inner wall of the installation port for convenient insertion of the intercepting net 5. A T-shaped plug rod 14 is slidably penetrated through the rotating frame 4 by a dragging mechanism, and a slot corresponding to the T-shaped plug rod 14 is provided on the intercepting net 5. A fixing plate 10 is provided on the blowing pipe 2, and a driving motor 11 is provided on the fixing plate 10, and the driving motor 11 is connected to the rotating frame 4 through a rotating mechanism.

[0023] The limiting mechanism includes a limiting ring 16 installed on the rotating frame 4, and an annular limiting groove corresponding to the limiting ring 16 is provided on the blowing pipe 2. As shown in the figure, the limiting ring 16 and the annular limiting groove are both T-shaped in vertical cross-section, wherein the annular limiting groove is not numbered, and its current state is designed corresponding to the limiting ring 16. The above-mentioned current states of the two can ensure that the rotating frame 4 can stably rotate outside the blowing pipe 2.

[0024] The dragging mechanism includes a dragging spring 15 which is sleeved on the outside of the T-shaped rod 14. The two ends of the dragging spring 15 are elastically connected to the outer wall of the head of the T-shaped rod 14 and the outer wall of the rotating frame 4 respectively. The dragging spring 15 realizes the dragging of the T-shaped rod 14 and ensures that the other end thereof can be stably located in the slot on the intercepting net 5 in the installation groove.

[0025] The rotating mechanism includes a driving gear 12 installed on the fixed plate 10 and connected to the output shaft of the driving motor 11. The rotating frame 4 is provided with an engaging ring gear 13 that meshes with the driving gear 12. With the help of the above-mentioned driving gear 12 and the engaging ring gear 13, the power transmission of the driving motor 11 is realized, and the rotation operation of the rotating frame 4 can be realized after the driving motor 11 is started.

[0026] A fixing ring 6 is fixedly provided on the blowing pipe 2, and a disassembly opening 7 is provided on the fixing ring 6. By means of the disassembly opening 7, the interception net 5 that has been removed from the rotating frame 4 can be disassembled by horizontal movement.

[0027] Multiple interception nets 5 are distributed at equal intervals around the rotating frame 4. The equal interval distribution makes it easy to rotate and adjust the interception nets 5. The adjustment range can be determined according to their number. For example, if six interception nets 5 are installed, the driving motor 11 can drive the rotating frame 4 to rotate 60 degrees at a time.

[0028] When the utility model is in use, the blowing pipe 2 can be hoisted and installed on the top of the wall of the processing workshop by relying on the hanging plate 1. The bag film body 8 is under the blowing pipe 2 and moves with the help of the roller assembly in the prior art. The wind is blown out by the blowing pipe 2 to realize the wind cooling and shaping operation. The cold wind is blown out through the blowing port 9 and is intercepted and filtered by the interception net 5 to avoid contamination to the bag film body 8. When the interception nets 5 corresponding to the multiple blowing ports 9 become dirty, the driving motor 11 is started, and the driving motor 11 drives the active gear 12 to rotate. The active gear 12 cooperates with the meshing gear ring 13 to drive the rotating frame 4 to rotate. The rotating frame 4 can rotate the other clean interception net 5 to correspond to the blowing port 9, and move the dirty one to correspond to the disassembly and assembly port 7. At this time, if it needs to be disassembled for cleaning or replacement, it only needs to drag the T-shaped plug rod 14 to disengage its end from the slot on the interception net 5, and then pull it horizontally to disengage it from the blowing port 9. If it does not need to be disassembled for cleaning or replacement, it can be rotated to one side without disassembly, and it can be cleaned with the help of a vacuum cleaner.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
