Description

Technical Field

[0001] This utility model relates to the field of PET plastic bottle processing technology, and more specifically, to a PET plastic bottle cooling device. Background Technology

[0002] PET plastic bottles are made from polyethylene terephthalate (PET). They are lightweight, transparent, impact-resistant, and have good barrier properties, making them widely used in packaging for beverages, edible oils, etc. They are marked with "1" and can be recycled into fibers, etc. The cooling device is a key piece of equipment in blow molding, using air cooling or water cooling (including annular fan rings, etc.) to rapidly cool and solidify the bottle, ensuring its precision and strength.

[0003] Publication No. (CN212171287U) discloses a PET plastic bottle cooling device, including a main body with a cooling box. The cooling box has an open-bottom structure and a through hole at its upper end. A cooling fan is installed inside the through hole, and a combing plate is connected to one side of the cooling box. A conveyor belt is located at the lower end of the main body, with a support frame installed at its lower end. Baffles are located on both sides of the upper end of the conveyor belt. A fixing plate is connected to the upper end of the support frame, and mounting blocks are provided on both sides of the fixing plate. Fixing clamps are evenly distributed at the upper end of the fixing plate, and cooling pipes are engaged on the fixing clamps. Fixing clamps are also provided inside the cooling box and inside the cooling fan. This PET plastic bottle cooling device allows bottle preforms to be cooled on the conveyor belt, facilitating the transport of the cooled preforms and improving the cooling efficiency of the preforms, thus effectively improving the processing efficiency of PET plastic bottles.

[0004] However, this PET plastic bottle cooling device has the following drawbacks: Although it can cool the plastic, in actual use, the air may contain impurities. When the air is blown directly onto the plastic bottle without being filtered, the impurities will adhere to the surface of the plastic bottle and stick to it as it cools. Furthermore, the air can only be blown onto the plastic bottle at a single angle for cooling, which will cause uneven local temperatures and deformation of the plastic bottle, greatly affecting its smoothness and quality. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a PET plastic bottle cooling device to solve the problem that the prior art cannot uniformly cool the plastic bottle from multiple angles by filtering the air.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a PET plastic bottle cooling device, comprising...

[0007] The bracket and motor are provided. A processing box is fixedly connected to the outside of the bracket. A filter plate is detachably connected to the inner wall of the processing box. Two pressure plates are slidably connected to the inner wall of the filter plate. A locking block is fixedly connected to the outside of each of the two pressure plates. An elastic element is fixedly connected to the end of each pressure plate away from the locking block. Two support plates are fixedly connected to the inner wall of the bracket.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1: Please refer to Figures 1 to 7 This utility model provides a technical solution: a PET plastic bottle cooling device, including a bracket 1 and a motor 3. A processing box 2 is fixedly connected to the outside of the bracket 1. A filter plate 4 is detachably connected to the inner wall of the processing box 2. Two pressure plates 13 are slidably connected to the inner wall of the filter plate 4. A locking block 5 is fixedly connected to the outside of each of the two pressure plates 13. An elastic element 6 is fixedly connected to the end of the pressure plate 13 away from the locking block 5. Two support plates 14 are fixedly connected to the inner wall of the bracket 1. A diversion cone plate 15 is fixedly connected to the inner wall of each of the two support plates 14. The outside of the locking block 5 is in contact with the inner wall of the processing box 2. The end of the elastic element 6 away from the locking block 5 is fixedly connected to the inner wall of the processing box 2.

[0026] The cooperation between the locking block 5 and the elastic element 6 enables the quick disassembly of the filter plate 4 for subsequent rapid maintenance. The filter plate 4 effectively filters impurities in the air, improving the production quality of plastic bottles. Furthermore, the support plate 14 and the diversion cone plate 15 provide uniform cooling for the plastic bottles, preventing deformation caused by localized over-cooling during heat dissipation, which would otherwise reduce the production quality of the plastic bottles.

[0027] Example 2: Based on Example 1, in order to facilitate heat dissipation of the plastic bottle, the inner wall of the support 1 is provided with two air guide grooves 16, the support 1 is provided with two output grooves 17, the inner wall of the processing box 2 is provided with two connecting grooves 12, and the inner wall of the processing box 2 is provided with two card slots 11.

[0028] When the motor 3 drives the fan to rotate and allow air to enter the interior of the bracket 1, the air first blows from the output slot 17 onto the diversion cone 15 in the support plate 14. Under the influence of the holes in the support plate 14 and the diversion cone 15, the air is blown out evenly from the holes to cool the plastic bottle. Since the diversion cone 15 is cone-shaped, some air will enter the air guide slot 16 under its influence and then be discharged to cool the plastic bottle. This achieves uniform cooling of the plastic bottle from multiple angles, enabling rapid and uniform cooling of the plastic bottle and improving production efficiency.

[0029] Example 3: Based on Example 2, in order to facilitate the movement of the locking block 5, the end of the locking block 5 away from the elastic element 6 is locked into the inner wall of the locking groove 11. The two pressure plates 13 are fixedly connected to the adjacent ends of the two pressure plates 13. A pull ring 8 is sleeved on the outside of the pull rope 17. A pull rope 9 is fixedly connected to the outside of the pull ring 8. A pull plate 10 is fixedly connected to the end of the pull rope 29 away from the pull ring 8. The outside of the filter plate 4 is slidably connected to the inner wall of the connecting groove 12. The outside of the pull rope 17 is slidably connected to the inner wall of the filter plate 4. The outside of the pull rope 29 is slidably connected to the inner wall of the filter plate 4. The outside of the pull plate 10 is in contact with the outside of the filter plate 4.

[0030] By starting the motor 3 in the processing box 2, the motor 3 drives the fan to rotate, drawing in outside air filtered through the filter plate 4 and then into the support 1 to cool the PET plastic bottles. After prolonged filtration of air, impurities may accumulate in the filter plate 4. At this point, by pulling the pull plate 10, the second pull rope 9 pulls the first pull rope 7 through the pull ring 8. The force applied to the first pull rope 7 pulls the pressure plates 13 at both ends, causing the pressure plates 13 to compress the elastic element 6. This allows the elastic element 6 to deform and release space, causing the locking block 5 to leave the slot 11 in the processing box 2 and no longer lock. This allows for quick disassembly of the filter plate 4, facilitating subsequent maintenance. Furthermore, the filter plate 4's filtration of impurities in the air prevents impurities from being blown onto the surface of the plastic bottle, thus avoiding impurities from becoming embedded in the bottle's surface during subsequent cooling, which would severely affect the product quality.

[0031] The working process of this utility model is as follows:

[0032] First, by starting the motor 3 in the processing chamber 2, the motor 3 drives the fan to rotate, drawing in outside air filtered through the filter plate 4 and then feeding it into the support 1 to cool the PET plastic bottles. After prolonged air filtration, impurities may accumulate in the filter plate 4. At this point, pulling the pull plate 10 causes the pull rope 2 9 to pull the pull rope 1 7 via the pull ring 8. The force applied to the pull rope 1 7 pulls the pressure plates 13 at both ends, causing the pressure plates 13 to compress the elastic element 6. This deformation of the elastic element 6 releases the space, allowing the locking block 5 to disengage from the slot 11 in the processing chamber 2, thus enabling quick disassembly of the filter plate 4 and facilitating subsequent maintenance. Furthermore, the filter plate 4 effectively filters impurities from the air. Under this action, impurities in the air are prevented from being blown onto the surface of the plastic bottle, thus avoiding the presence of impurities on the bottle's surface. Furthermore, these impurities would become fixed on the bottle's surface during subsequent cooling, severely impacting production quality. Specifically, when the motor 3 drives the fan to rotate, allowing air to enter the support 1, the air first blows from the output slot 17 onto the diversion cone 15 in the support plate 14. The holes in the support plate 14 and the diversion cone 15 allow for uniform airflow, cooling the plastic bottle. Because the diversion cone 15 is cone-shaped, some air enters the air guide slot 16 and is subsequently discharged, further cooling the plastic bottle. This achieves uniform cooling of the plastic bottle from multiple angles, enabling rapid and uniform cooling and improving production efficiency.
