Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, and in particular to a rapid cooling and shaping device for plastic products. Background Technology

[0002] In the industrial production of plastic products, processes such as injection molding, extrusion molding, and blow molding all require a cooling and solidification step to rapidly solidify the molten plastic. Cooling efficiency directly affects the molding accuracy, surface quality, mechanical properties, and production cycle of the finished product. Traditional cooling methods include natural cooling, water cooling, and air cooling.

[0003] Natural cooling is too slow, and some plastic products require rapid cooling and shaping, making it unsuitable for natural cooling. Water cooling, on the other hand, is widely used in industry, offering good cooling performance and rapid shaping. However, water cooling is more expensive, and water-cooled plastic products often require drying, adding an extra step and reducing production efficiency.

[0004] Air cooling is not only low-cost but also highly efficient. However, air cooling typically requires placing the plastic product in one spot to dissipate heat, resulting in uneven heating and inconsistent heat distribution across different parts of the product. Furthermore, moving and placing the plastic product during cooling and shaping can easily lead to compression or impacts, potentially causing deformation. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a rapid cooling and shaping device for plastic products, so as to solve the technical problem in the prior art of how to cool plastic products quickly and cost-effectively while ensuring uniform heating and avoiding extrusion deformation.

[0006] To achieve the above objectives, this utility model provides a rapid cooling and shaping device for plastic products, including a feed hopper installed below the discharge port of a plastic production device, and the rapid cooling and shaping device further includes:

[0007] A straight pipe is fixedly connected below the feed hopper, and the straight pipe is provided with several rows of air jet holes, which are arranged at equal angles on the inner wall of the straight pipe;

[0008] An air intake pipe is provided outside the straight pipe, the inner end of which is connected to the jet hole, and the outer end of which is connected to the air pump.

[0009] Furthermore, several external tubes are fixedly connected to the outer wall of the straight tube, and each row of jet holes is connected to the same external tube. The external tube is a square tube, and the air inlet pipe is fixedly connected to the external tube.

[0010] Furthermore, a pressure chamber is provided inside the external tube, the outlet end of the jet hole is obliquely upward and communicates with the inner cavity of the straight tube, while the inlet end of the jet hole is communicated with the pressure chamber.

[0011] Furthermore, the jet holes are arranged in 4-6 rows, and each row has 10-20 jet holes.

[0012] Furthermore, the intake pipe is also provided with several pipes, and each intake pipe is connected to a row of jet holes.

[0013] Furthermore, a soft pad is provided on the inner wall of the feed hopper.

[0014] Furthermore, the bottom of the straight pipe is provided with a discharge pipe, which is a curved pipe with a high degree of bending, and the outlet end of the discharge pipe faces the receiving box.

[0015] Furthermore, the upper end of the discharge pipe is provided with several elastic ropes, both ends of which are fixedly connected to the inner wall of the discharge pipe. Multiple elastic ropes are arranged in an alternating pattern to create multiple openings, and each opening allows plastic products to pass through.

[0016] The beneficial effects of this utility model are as follows: 1. A feeding hopper is installed below the discharge port of the production equipment, and a soft pad is provided on the inner wall of the feeding hopper. A straight pipe is connected below the feeding hopper. Therefore, after the plastic products are produced, they can directly enter the straight pipe through the feeding hopper for air cooling and shaping. Finally, the plastic products are collected in the receiving box by the discharge pipe conveyor belt below the straight pipe. Thus, air cooling and shaping are achieved during the material conveying process, eliminating the need for an additional cooling and shaping station, reducing costs and improving efficiency.

[0017] 2. Multiple rows of air jet holes are set on the inner wall of the straight pipe, and these rows of air jet holes are arranged at equal angles. Air is sprayed from multiple directions through the air jet holes to cool and shape the plastic product, ensuring that the plastic product can dissipate heat synchronously and be heated evenly from all directions. This not only improves the efficiency of cooling and shaping, but also makes the shaping effect better.

[0018] 3. The air outlet of the jet nozzle is set at an angle upward. By spraying air at an angle upward, it not only cools and shapes the plastic product, but also provides an upward thrust. Furthermore, because multiple rows of jet nozzles are set at equal angles, an upward airflow is formed. This upward airflow slows down the falling speed of the plastic product, extending the time the plastic product spends in the straight pipe and improving the cooling effect.

[0019] 4. Several elastic ropes are installed at the upper end of the discharge pipe, and multiple elastic ropes are arranged in an interlaced manner to create multiple openings. These elastic ropes are used to impede the falling of plastic products, which greatly reduces the falling speed of plastic products and alleviates the damage caused by impacts. Each opening allows plastic products to pass through without obstructing their passage. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0029] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, natural cooling is too slow, and some plastic products require rapid cooling and shaping, making it unsuitable for natural cooling. Water cooling is widely used in industry, offering good cooling and rapid shaping, but it is expensive, and water-cooled plastic products often require drying, adding an extra step and reducing production efficiency. Therefore, this solution uses air cooling for rapid cooling and shaping. First, a feed hopper 102 is installed below the discharge port of the plastic product production equipment, and a straight pipe 101 is fixedly connected below the feed hopper 102. Thus, after production, the plastic products can directly enter the straight pipe 101 through the feed hopper 102 for air cooling and shaping.

[0030] The key feature is that the straight pipe 101 has several rows of jet holes 106 arranged at equal angles on its inner wall. Several external pipes 103 are fixedly connected to the outer wall of the straight pipe 101, and each row of jet holes 106 is connected to the same external pipe 103. The external pipe 103 is a square tube, and the air intake pipe 104 is fixedly connected to the external pipes 103. The inner end of the air intake pipe 104 is connected to the jet holes 106, and the outer end of the air intake pipe 104 is connected to the air pump.

[0031] The plastic product is cooled and shaped by air jets from multiple directions through the jet holes 106, ensuring that heat is dissipated synchronously and evenly from all directions. This not only improves the efficiency of cooling and shaping but also results in a better shaping effect.

[0032] Preferably, the jet nozzles 106 are arranged in 4-6 columns, and each column preferably has 10-20 jet nozzles 106.

[0033] In addition, an air pressure chamber 107 is provided inside the external tube 103. The outlet end of the jet hole 106 is obliquely upward and communicates with the inner cavity of the straight tube 101, while the inlet end of the jet hole 106 is communicated with the air pressure chamber 107. Several air inlet pipes 104 are also provided, and each air inlet pipe 104 is connected to a row of jet holes 106.

[0034] Preferably, a soft pad is provided on the inner wall of the feed hopper 102.

[0035] The exhaust port 106 is angled upwards at its outlet. By spraying air upwards at an angle, it not only cools, shapes, and dissipates heat from the plastic product, but also provides an upward thrust. Furthermore, because multiple rows of exhaust ports 106 are arranged at equal angles, an upward airflow is ultimately formed. This upward airflow slows down the falling speed of the plastic product, extending the time the plastic product spends within the straight pipe 101 and improving the cooling effect.

[0036] The second aspect of this utility model is as follows: Figure 1 , Figure 3 and Figure 4 As shown, since air cooling typically requires placing plastic products in one location for heat dissipation, different parts of the product experience varying heat dissipation, resulting in uneven heating. Furthermore, the movement and placement of plastic products during cooling and shaping can easily lead to compression or impacts, potentially causing deformation. Therefore, this embodiment uses a feed hopper 102, a straight pipe 101, and a discharge pipe 105 to form a conveyor for transporting plastic products, allowing for simultaneous air cooling and shaping during transport.

[0037] Specifically, the discharge pipe 105 is fixedly connected to the bottom of the straight pipe 101, and the discharge pipe 105 is a 90-degree bent pipe, with the outlet end of the discharge pipe 105 facing the receiving box.

[0038] A feed hopper 102 is installed below the discharge port of the production equipment, and a soft pad is provided on the inner wall of the feed hopper 102. Therefore, after the plastic products are produced, they can directly enter the straight pipe 101 through the feed hopper 102 for air cooling and shaping. Finally, the plastic products are collected in the receiving box by the conveyor belt of the discharge pipe 105 below the straight pipe 101. Thus, air cooling and shaping can be achieved during the material conveying process, eliminating the need for an additional cooling and shaping station, reducing costs and improving efficiency.

[0039] In addition, several elastic ropes 108 are provided at the upper end of the discharge pipe 105. Both ends of the elastic ropes 108 are fixedly connected to the inner wall of the discharge pipe 105, and multiple elastic ropes 108 are arranged in an alternating manner to create multiple openings, and each opening can allow plastic products to pass through.

[0040] These elastic cords 108 are used to impede the falling of plastic products, greatly reducing the speed at which they fall and mitigating damage from impacts. Each opening allows plastic products to pass through without obstructing their passage.

[0041] In summary, this utility model 1 features a feeding hopper 102 located below the discharge port of the production equipment, with a soft pad on the inner wall of the feeding hopper 102. A straight pipe 101 connects to the bottom of the feeding hopper 102, allowing plastic products to directly enter the straight pipe 101 for air cooling and shaping after production. Finally, the plastic products are conveyed to a receiving box via a discharge pipe 105 below the straight pipe 101. This achieves air cooling and shaping during material conveying, eliminating the need for an additional cooling and shaping station, reducing costs and increasing efficiency. Several elastic ropes 108 are located at the upper end of the discharge pipe 105, arranged in a staggered pattern to create multiple openings. These elastic ropes 108 impede the falling of the plastic products, significantly reducing their falling speed and mitigating damage from impacts. Each opening allows the plastic products to pass through without obstructing their passage.

[0042] Multiple rows of air jets 106 are arranged at equal angles on the inner wall of the straight pipe 101. Air jets from multiple directions through these jets cool and shape the plastic product, ensuring simultaneous and uniform heat dissipation from all sides. This not only improves cooling and shaping efficiency but also enhances the shaping effect. Furthermore, the outlet ends of the jets 106 are angled upwards, providing an upward thrust while simultaneously cooling and shaping the plastic product. The multiple rows of equally angled jets 106 create an upward airflow, which slows the descent of the plastic product, extending its time within the straight pipe 101 and further improving cooling efficiency.
