DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0036] Embodiment 1

[0037] Please refer to Figures 1-8 The present application provides a technical solution:

[0038] The continuous extrusion molding device for producing environment-friendly isolation film comprises an extrusion molding equipment 1. During production, the extrusion molding equipment 1 precisely extrudes and molds the isolation film 2 through a specific process. In order to effectively cool the isolation film 2, the extrusion molding equipment 1 is provided with an isolation film cooling mechanism 3. After the isolation film 2 is extruded, it will pass through the isolation film cooling mechanism 3 before being wound.

[0039] In this embodiment, the isolation film cooling mechanism 3 mainly comprises a pair of bases 31 fixed on the extrusion molding equipment 1, a plurality of cooling cylinders 32 playing a key cooling role, a plurality of cooling pipes 33 assisting in cooling, and a fan 34 providing cooling air flow.

[0040] Specifically, the cooling cylinder 32 comprises a cylinder body 321, a sleeve 322 sleeved in the cylinder body 321, an end cover 323 installed at the end of the cylinder body 321, and an end cover 324 arranged at the front end of the cylinder body 321 and fixedly connected with the base 31. The cooling cylinder 32 is located between the two bases 31 and is rotatably connected with the base 31. The isolation film 2 passes through the outside of the plurality of cooling cylinders 32 in sequence, so that the isolation film 2 can be in contact with the surface of each cooling cylinder 32. When the isolation film 2 is wound, the isolation film 2 can drive the cooling cylinder 32 to rotate under the action of friction, so that the heat on the isolation film 2 can be conducted to the cooling cylinder 32 when the isolation film 2 drives the cooling cylinder 32 to rotate.

[0041] Further, the sleeve 322 is in the shape of a hollow cylinder, and a plurality of annular fins 3221 are arranged at equal intervals in the sleeve 322. The outer end of the fin 3221 is connected with the inner wall of the sleeve 322, and the inner end of the fin 3221 extends to the central axis of the sleeve 322. The fins 3221 increase the heat dissipation area inside the cooling cylinder 32, so that the temperature on the surface of the cooling cylinder 32 can be quickly dissipated through the fins 3221, and the cooling effect is strengthened.

[0042] In addition, the outer end of the end cover 323 is provided with a hollow convex shaft 3231, which penetrates the base 31 and is rotatably connected with the base 31. An insertion column 3232 is arranged on the end face of the end cover 323 away from the convex shaft 3231, and the insertion column 3232 is inserted into the end of the cylinder body 321 and abuts against the sleeve 322, so that the sleeve 322 can be stably arranged inside the sleeve 322 under the action of the two insertion columns 3232. A flow guide opening 3233 in the shape of a horn is arranged on the inner end face of the insertion column 3232. The small aperture part of the flow guide opening 3233 is connected with the inside of the convex shaft 3231, and the diameter of the large aperture part of the flow guide opening 3233 is the same as the diameter of the insertion column 3232, which is used for guiding the airflow into the inside of the sleeve 322.

[0043] It is worth noting that the end cover 324 is used to cover and protect the end of the convex shaft 3231. The outer end of the end cover 324 is provided with a connecting pipe 3242, and the inner end face of the end cover 324 is provided with a cover cavity 3241. The leading end of the connecting pipe 3242 is inserted into the end cover 324.

[0044] It is worth mentioning that the cooling pipe 33 is placed parallel between two adjacent cooling cylinders 32, the cooling pipe 33 penetrates and is fixed between two bases 31, the isolation film 2 passes above the cooling pipe 33, a plurality of air outlet holes 331 are arranged on the upper surface of the cooling pipe 33, and an end plug 332 is fixed to the rear end of the cooling pipe 33, so that the rear end of the cooling pipe 33 is blocked. The air outlet end of the fan 34 is connected with a air supply pipe 341, the front end of the connecting pipe 3242 and the cooling pipe 33 are connected with the air supply pipe 341 in communication, and the end of the air supply pipe 341 is closed. When the fan 34 is started, the fan 34 blows air into the air supply pipe 341, so that the air enters the end cover 324 through the connecting pipe 3242, the air enters the inside of the sleeve 322 through the convex shaft 3231 and is discharged from the other end of the sleeve 322, and along with the flow of the air, the air carries the heat emitted from the surface of the fin 3221, so that the cooling cylinder 32 can be quickly cooled. At the same time, the air in the air supply pipe 341 directly enters the cooling pipe 33, so that the air is blown upward to the isolation film 2 through the air outlet holes 331, and the purpose of further cooling the isolation film 2 is achieved.

[0045] In use, the continuous extrusion molding device for producing the environment-friendly isolation film of the embodiment first extrudes the isolation film 2 through the extrusion molding equipment 1, then the isolation film 2 enters the isolation film cooling mechanism 3 and sequentially winds through the outside of the plurality of cooling cylinders 32, the fan 34 in the cooling mechanism is started, the air outside is sucked and blown into the air supply pipe 341 as a source of cooling air, then a part of the air in the air supply pipe 341 enters the end cover 324 through the connecting pipe 3242 and flows into the sleeve 322 along the convex shaft 3231, so that the air flows through the inside of the sleeve 322, then when the isolation film 2 is wound, the cooling cylinder 32 is driven to rotate due to the friction, and the heat on the isolation film 2 is conducted to the cooling cylinder 32, so that the cooling cylinder 32 cools and cools the isolation film 2, and at this time, the air flow through the fin 3221 can quickly take away the heat on the surface of the cooling cylinder 32, so as to realize the primary cooling of the isolation film 2, and finally, the other part of the air in the air supply pipe 341 directly enters the cooling pipe 33, the air in the cooling pipe 33 blows upward to the isolation film 2 through the air outlet holes 331, so as to further cool and cool the isolation film 2, and the whole cooling process is completed.

[0046] Embodiment 2

[0047] In order to prevent the air flow from blowing dust and other impurities in the air to the isolation film 2, the air supply pipe 341 is provided with a filter 342, and the filter 342 is arranged on the air supply pipe 341. Figure 9 and Figure 10As shown, the outlet end of the fan 34 and the head end of the air supply pipe 341 are provided with a sleeve 342, the head end and the tail end of the sleeve 342 are provided with a convex pipe 3421, the convex pipe 3421 at the two ends of the sleeve 342 is respectively inserted into the outlet end of the fan 34 and the head end of the air supply pipe 341, the sleeve 342 is filled with a filter core 3422, and it is worth mentioning that the outer diameter of the convex pipe 3421 is smaller than the outer diameter of the sleeve 342, so that the filter core 3422 can be stably clamped in the sleeve 342, preventing the filter core 3422 from being blown away under the strong wind of the fan 34, and ensuring the stability of the filtering structure. When the fan 34 is running, external air is sucked in, and in the process of passing through the sleeve 342, dust, particles and other impurities in the air are effectively intercepted and filtered by the filter core 3422, so that the clean airflow after purification enters the air supply pipe 341 and finally flows to the cooling cylinder 32 and the cooling pipe 33, which greatly reduces the risk of dust and other impurities adhering to the surface of the isolation film 2, ensures the cleanliness of the isolation film 2, and improves the product quality.

[0048] Moreover, the structure is very convenient to install and maintain. When the filter core 3422 needs to be replaced, the worker only needs to pull out the convex pipe 3421 at the two ends of the sleeve 342, so as to take out the sleeve 342 from between the fan 34 and the air supply pipe 341, and then quickly replace the internal filter core 3422, which is simple and efficient, and effectively saves equipment maintenance time and cost.

[0049] It is worth mentioning that the fan 34 involved in the present application is a conventional technology, which will not be described in the present application.

[0050] The basic principles, main features and advantages of the present application have been shown and described. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and do not limit the present application.
