Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a PET film gluing and drying tunnel component. Background Art

[0002] PET film drying is an important and indispensable procedure in the entire preparation process.

[0003] In the existing PET film drying process, the PET film is usually directly sent into a shell with a relatively high temperature.

[0004] Since the PET film needs to be fed into and taken out of the shell, an inlet and an outlet need to be opened on the shell. The setting of the inlet and outlet will cause the temperature in the shell to dissipate faster. Therefore, it is difficult to ensure that the temperature value in the shell is always maintained within the set range, resulting in poor stability. Summary of the invention

[0005] The purpose of the utility model is to provide a PET film gluing oven assembly with high stability and compact structure in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A PET film gluing drying tunnel assembly comprises a shell with a cavity inside, the shell is in a rectangular shape, and both ends of the shell have an inlet and an outlet connected to the inner cavity thereof. The assembly is characterized in that it also comprises an input pipe assembly and an output pipe assembly, the inner end of the input pipe assembly is located in the shell, and the outer end of the input pipe assembly extends out of the upper part of the shell, the inner end of the output pipe assembly is located in the shell, and the outer end of the output pipe assembly extends out of the upper part of the shell, the number of the input pipe assemblies and the output pipe assemblies is several, and the several input pipe assemblies and the output pipe assemblies are arranged adjacent to each other front to back along the length direction of the shell.

[0008] The PET film gluing drying tunnel component creatively arranges a plurality of front and rear adjacent input pipe components and output pipe components on the shell. The input pipe component can stably input the high-temperature airflow into the shell, and the output pipe component can stably transport the excess air along the shell to the smoke purification device.

[0009] Under the action of the input pipe assembly and the output pipe assembly, the high-temperature airflow can circulate in the shell, and the PET film in the shell is finally stably dried.

[0010] In the above-mentioned PET film gluing drying tunnel assembly, the input pipe assembly includes a main pipe, a connecting section and a branch pipe. The connecting section is arranged horizontally, and the number of the branch pipes is two. The two branch pipes are respectively connected to the two ends of the connecting section and are connected to each other. The inner end of the main pipe is connected to the middle of the connecting section, and the outer end of the main pipe is used to communicate with the hot air source. The branch pipe is located in the shell and has an air outlet on the branch pipe.

[0011] The main pipe is used to connect the hot air source, and under the action of the connecting section, the hot air source stably enters the shell through the two branch pipes.

[0012] In the above-mentioned PET film glue coating oven assembly, the main pipe is arranged transversely and is parallel to the top of the shell.

[0013] The transversely arranged main pipe can make it occupy less space and appropriately improve its structural compactness.

[0014] In the above-mentioned PET film gluing oven assembly, the branch pipe is close to the inner wall of the shell.

[0015] Such a structure can prevent the branch pipe from occupying too much space in the shell.

[0016] In the above-mentioned PET film gluing drying tunnel assembly, the number of the air outlets is several, and the several air outlets are evenly distributed along the height direction of the branch pipe.

[0017] The arrangement of multiple air outlets can input the hot air source to various positions in the shell, that is, each position in the shell has a relatively high height.

[0018] In the above-mentioned PET film gluing drying tunnel assembly, the output pipe assembly includes a guide cover and a guide pipe. The guide cover is fixedly connected to the top of the shell, the inner end of the guide pipe is connected to the guide cover, and the outer end of the guide pipe is used to connect to the smoke filtering device.

[0019] The smoke can stably enter the guide pipe through the guide cover, and since the guide pipe is used to communicate with the smoke filter device, the component causes as little pollution to the environment as possible during use.

[0020] In the above-mentioned PET film gluing drying tunnel assembly, the guide cover is cylindrical, the size of the lower end port of the guide cover is larger than the size of the upper end port of the guide cover, the lower end of the guide cover is fixedly connected to the upper part of the shell and the guide cover is connected to the inner cavity of the shell, and the inner end of the guide pipe is fixedly connected to the upper end of the guide cover and the two are connected.

[0021] Such a structure can allow smoke to smoothly enter the guide pipe.

[0022] In the above-mentioned PET film glue coating oven assembly, the above-mentioned guide pipe is located between two adjacent main pipes and the guide pipe is arranged in parallel with the main pipes.

[0023] This can effectively improve the structural compactness of the upper portion of the entire assembly.

[0024] In the above-mentioned PET film gluing drying tunnel assembly, there are several flow guide covers, which are evenly distributed at the top of the shell along the length direction of the flow guide tube, and each flow guide cover connects the inner cavity of the shell with the flow guide tube.

[0025] The provision of multiple deflector covers can enable smoke to enter the deflector pipe more stably and smoothly.

[0026] Compared with the prior art, the PET film gluing drying tunnel assembly has a plurality of input pipe assemblies and output pipe assemblies on the shell, so that the high-temperature airflow can circulate in the shell. As long as the input pipe assembly continuously and constantly inputs the high-temperature airflow, the temperature in the shell can be maintained within the set range. Therefore, its drying stability is relatively high.

[0027] At the same time, the main pipe and the guide pipe are arranged on the shell at the same height and are adjacent to each other in parallel front and back. The structure is relatively compact and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
