Description

Technical Field

[0001] This application relates to the field of food packaging technology, and in particular to a cooling mechanism for a packaging machine. Background Technology

[0002] Packaging machines are machines used for product packaging, protecting and beautifying the products to be packaged. Food production packaging machines, in particular, are used to preserve freshness, protect food safety, and enhance the appearance of packaged foods, and are widely used in the food packaging industry. In the streamlined food production process, some processed foods are at high temperatures and cannot be packaged directly. Therefore, during the packaging process, cooling fans are generally used to cool the food inside the package.

[0003] The published patent document CN211732052U discloses a food packaging machine with a cooling mechanism. This patent document uses a cooler and a cooling pipe to facilitate cooling of the food by cooling the inside of the cooling cylinder. The cooled food is then output to the conveyor belt through the discharge pipe. However, the aforementioned patent document only uses water cooling as the cooling method, which results in a slow cooling effect. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a cooling mechanism for a packaging machine, which overcomes the shortcomings of the prior art and aims to solve the problem that the cooling effect is slow when cooling food by only water cooling.

[0005] To achieve the above objectives, this application provides the following technical solution: a cooling mechanism for a packaging machine, comprising a cooling cylinder, a cooling water circulation pipe sleeved around the outer surface of the cooling cylinder, a feed hopper fixedly installed at the top of the cooling cylinder, a discharge pipe fixedly installed at the bottom of the cooling cylinder, a conveying pipe fixedly installed on the inner wall of the cooling cylinder, an air-cooled heat sink fixedly installed inside the cooling cylinder on the inner side of the conveying pipe, an air inlet of the air-cooled heat sink fixedly connected to the air outlet of the air-cooling mechanism through an air supply pipe, a rotating frame arranged near the lower end inside the air-cooled heat sink, and a filter screen arranged inside the rotating frame.

[0006] By adopting the above technical solution, the cooling water circulation pipe and the matching water-cooled cooler are used to facilitate water cooling of the cooling cylinder, thereby cooling the food. The air-cooled heat dissipation cylinder, air supply pipe and air-cooling mechanism work together to ensure that cooling air can be effectively transferred from the air-cooling mechanism to the interior of the cooling cylinder, thereby achieving effective heat dissipation of the food. By setting a filter screen to filter the cooling air delivered by the air-cooling mechanism, impurities and bacteria are removed to ensure food safety. This device can achieve simultaneous heat dissipation and cooling of food by both water cooling and air cooling, improving cooling efficiency, shortening cooling time and improving work efficiency.

[0007] As a preferred technical solution of this application, an installation groove is provided inside the air-cooled heat sink near the lower end, and mounting seats are symmetrically connected on both sides of the outer wall of the air-cooled heat sink on the mounting groove. A rotating rod is fixedly installed inside one of the mounting seats, and the rotating frame is rotatably sleeved on the outer surface of the rotating rod.

[0008] By adopting the above technical solution, and by setting a rotating rod and a mounting base, the rotating frame is movably installed inside the mounting slot, so that the staff can replace the filter screen.

[0009] As a preferred technical solution of this application, another mounting base has a threaded hole through the top and a fixing bolt is threadedly connected to the threaded hole, and the mounting base is fixedly installed to the rotating frame by the fixing bolt.

[0010] By adopting the above technical solution, the rotating frame is limited and fixed by setting fixing bolts to prevent the rotating frame from shifting position during operation, and to ensure that the filter screen can filter the cooling air delivered by the air-cooling mechanism.

[0011] As a preferred technical solution of this application, the upper surface of the rotating frame is provided with symmetrical limit holes on both sides of the filter screen, and the inner diameter of the limit holes is adapted to the outer diameter of the rotating rod and the fixing bolt respectively.

[0012] By adopting the above technical solution, the necessary conditions for the installation of the rotating frame are provided.

[0013] As a preferred technical solution of this application, the outer surface of the air-cooled heat sink is provided with a number of air outlets located inside the cooling cylinder, and the outer surface of the air-cooled heat sink is provided with a vent above the cooling cylinder.

[0014] By adopting the above technical solution, it is ensured that cooling air can be effectively transferred from the air-cooled heat sink to the interior of the cooling cylinder to cool the food.

[0015] As a preferred embodiment of this application, the conveying pipe is spiral in shape and extends downwards, with its upper end connected to the lower end of the feed hopper and its lower end connected to the upper end of the discharge pipe.

[0016] By adopting the above technical solution, the material conveying pipeline is set in a spiral shape and downward direction, which effectively propels the material forward. The spiral downward design can increase the fluidity of the material, reduce the possibility of blockage, and also facilitate the uniform conveying of the material.

[0017] As a preferred technical solution of this application, a support leg is fixedly installed on the lower surface of the cooling cylinder, and the number of the support legs is four and they are evenly distributed in a linear array on the lower surface of the cooling cylinder.

[0018] By adopting the above technical solution, the stability of the cooling cylinder during placement is ensured.

[0019] As a preferred technical solution of this application, the cooling cylinder, conveying pipe, discharge pipe, feed hopper and air-cooled heat dissipation cylinder are all made of food-grade stainless steel.

[0020] By adopting the above technical solutions, it is ensured that food will not be contaminated with harmful substances during the cooling process, thus ensuring food safety.

A conveying pipe 5 is fixedly installed on the inner wall of the cooling cylinder 1. An air-cooled heat sink 6 is fixedly installed inside the cooling cylinder 1, inside the conveying pipe 5. The air inlet of the air-cooled heat sink 6 is fixedly connected to the air outlet of the air-cooling mechanism 7 through an air supply pipe 8. A rotating frame 10 is provided near the lower end inside the air-cooled heat sink 6. A filter screen 9 is provided inside the rotating frame 10. During use, the cooling water circulates... The cooperation between pipe 2 and the water-cooled cooler that matches the cooling water circulation pipe 2 facilitates water cooling of the cooling cylinder 1, thereby cooling the food. The cooperation between the air-cooled heat dissipation cylinder 6, the air supply pipe 8, and the air-cooling mechanism 7 ensures that cooling air can be effectively transferred from the air-cooling mechanism 7 to the interior of the cooling cylinder 1, thereby achieving effective heat dissipation of the food. The cooling air delivered by the air-cooling mechanism 7 is filtered by the filter screen 9 to remove impurities and bacteria, ensuring food safety. This device can achieve simultaneous heat dissipation and cooling of food by both water cooling and air cooling, improving cooling efficiency, shortening cooling time, and increasing work efficiency.

The outer wall of the air-cooled heat sink 6 is symmetrically connected to the two sides of the installation groove 11 with mounting seats 12.

In use, by setting the rotating rod 16 and the mounting seat 12, the rotating frame 10 is movably installed inside the installation groove 11, so that the staff can replace the filter screen 9.

[0032] In this embodiment, as Figure 4 As shown, another mounting base 12 has a threaded hole 14 through the top and a fixing bolt 15 is threadedly connected through the threaded hole 14. The mounting base 12 is fixedly installed to the rotating frame 10 by the fixing bolt 15. In use, the rotating frame 10 is limited and fixed by the fixing bolt 15 to prevent the rotating frame 10 from shifting position during operation, and to ensure that the filter screen 9 can filter the cooling air delivered by the air-cooling mechanism 7.

[0033] In this embodiment, as Figure 4 As shown, the upper surface of the rotating frame 10 has symmetrical limit holes 13 on both sides of the filter screen 9.

The upper end of the conveying pipe 5 is connected to the lower end of the feed hopper 3, and the lower end of the conveying pipe 5 is connected to the upper end of the discharge pipe 4. In use, by setting the conveying pipe 5 into a spiral shape and a downward direction, the material is effectively pushed forward. The spiral downward design can increase the fluidity of the material, reduce the possibility of blockage, and also facilitate the uniform conveying of the material.

[0036] In this embodiment, as Figure 2 As shown, four support legs 19 are fixedly installed on the lower surface of the cooling cylinder 1 and are evenly distributed in a linear array on the lower surface of the cooling cylinder 1 to ensure the stability of the cooling cylinder 1 when it is placed during use.

During use, this ensures that food will not be contaminated with harmful substances during the cooling process, thus ensuring food safety.

[0038] Working principle: When using the cooling mechanism for a packaging machine according to this application, the cooling water circulation pipe 2 and the matching water-cooled cooler work together to cool the cooling cylinder 1, thereby cooling the food. The air-cooled heat dissipation cylinder 6, the air supply pipe 8 and the air-cooling mechanism 7 work together to ensure that the cooling air can be effectively transferred from the air-cooling mechanism 7 to the interior of the cooling cylinder 1, thereby achieving effective heat dissipation of the food.
