Description

Technical Field

[0001] The utility model belongs to the field of manufacturing and production of notebook shells, and specifically relates to a device for blowing and removing films on holes. Background Art

[0002] The shell of a notebook is usually divided into shells A, B, C, and D. Shell A represents the back cover of the screen (the top surface of the notebook cover), shell B represents the front frame of the screen (the circle around the liquid crystal screen), shell C represents the upper cover of the main body (surrounding the keyboard - generally including the palm rest and usually also including the touchpad), and shell D represents the lower cover of the main body (the bottom).

[0003] Currently, during the manufacturing and production of notebook shells, a film needs to be coated on the notebook shell to protect the notebook shell, thereby reducing scratches. However, during the process of coating the film on the notebook shell, the film will be directly pressed on the shell. After the film coating is completed, the film on the hole part of the notebook shell is blown off by a compressed gas jet head on the device. At this time, film waste fragments will be left on the table. If the film waste fragments are not cleaned up in time, it will affect the subsequent film coating process of the notebook shell.

[0004] Therefore, we propose a device for blowing and removing films on holes to solve the problems mentioned above. Content of the Utility Model

[0005] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a device for blowing and removing films on holes.

[0006] To solve the above problems, the technical solution adopted by the utility model is as follows: A device for blowing and removing films on holes includes a production rack for placing a notebook shell and a bracket arranged at the upper end of the production rack. There are also holes on the surface of the notebook shell. A roller is arranged inside the bracket, and a film is covered on the surface of the roller. After the notebook shell passes through the roller, the film will be pressed on the shell. It also includes a compressed gas jet head placed at the upper end of the bracket. A cleaning component is also arranged on the surface of the production rack, and the cleaning component is used for collecting film waste fragments. The cleaning component includes a fitting plate arranged on the surface of the production rack and air holes evenly opened on the surface of the fitting plate. Gas can flow through the air holes. The lower end of the fitting plate is hermetically connected to an air diffuser hood. The lower end of the air diffuser hood is connected to a collection structure for collecting waste fragments. One side of the collection structure is connected to a conduit. The end of the conduit far from the collection structure is connected to an air pump. The other end of the air pump is connected to an exhaust pipe. When the air pump is started, air can be pumped through the conduit, so that air and film waste fragments enter the air diffuser hood through the air holes and finally are moved into the collection structure for collection.

[0007] Preferably, multiple sets of compressed gas jet heads are provided and connected to a compressor through pipelines. When the compressor is started, the compressed gas jet heads can eject compressed gas to blow off the film on the hole part of the notebook shell.

[0008] Preferably, a cross plate is arranged at the upper end of the production rack, and a cross bar is arranged on one side of the cross plate. The whole formed by the cross plate and the cross bar can support the compressed gas jet head.

[0009] Preferably, a dust-proof cover is sleeved on the outer side of the end of the exhaust pipe far away from the air pump, and the dust-proof cover is used for dust prevention.

[0010] Preferably, the collection structure includes a collection frame and a cover plate hinged to the opening of the collection frame. A filter screen for filtering is installed inside the collection frame. The filter screen can filter the gas, so that the film waste fragments are retained in the collection frame.

[0011] Preferably, an electric push rod is installed on the outer side of the collection frame, and the telescopic end of the electric push rod is connected with a push plate. The push plate is placed inside the collection frame. When the electric push rod operates, it can push the push plate to move, and can push the film waste fragments out of the collection frame.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the arranged roller, compressed gas jet head and cleaning member, after the notebook shell passes through the roller 3, the film will be pressed on the shell. After the film covering is completed, the compressed gas jet head 4 on the equipment blows off the film on the hole part of the notebook shell, and then the cleaning member can clean the film waste fragments on the surface of the production rack and collect them, making the surface of the production rack clean and conducive to subsequent film covering of the notebook shell.

[0014] 2. Through the arranged electric push rod and push plate, the film waste fragments in the collection frame can be pushed out of the collection frame, which is convenient for taking out the film waste fragments, with simple operation and labor saving. BRIEF DESCRIPTION OF THE DRAWINGS
