Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packaging production equipment, and particularly relates to an inner frame paper oil injection device. Background Art

[0002] During the transportation process of the inner frame paper, there is dust attached to the surface. If not cleaned for a long time, it will cause quality defects such as discoloration of the inner frame paper, blockage of the inner frame paper transportation, and creases on the inner frame paper. Therefore, it is necessary to regularly oil the inner frame paper. In the transportation process section of the inner frame paper, the inner frame paper extends from the head of the inner frame paper roll and is wound around a plurality of paper guide rollers in sequence, and the inner frame paper is guided and transported by relying on the plurality of paper guide rollers.

[0003] In the prior art, the oil injection method for the inner frame paper is as follows: A felt is installed at the paper guide roller close to the inner frame paper roll. The felt is manually oiled by hand holding an oil pot, and then the oil is coated on the surface of the inner frame paper in contact with it through the felt. This oil injection method has the following disadvantages: Since manual oiling of the felt is required, it is difficult to control the oil injection time and the amount of oil injected. When the oil injection is not timely, quality defects such as discoloration of the inner frame paper are likely to occur; if the oil injection is excessive and too much oil adheres to the inner frame paper, it will affect the subsequent wrapping and forming of the inner frame paper.

The following embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.

[0017] See Figures 1 to 3, this embodiment discloses an inner frame paper oil injection device. The conveying process section of the inner frame paper 14 includes a frame 1, on which a paper roll mounting shaft 2 and multiple guide rollers are installed. The paper roll mounting shaft 2 is used to mount the inner frame paper roll 3, and the multiple guide rollers are used to guide and convey the inner frame paper 14. Among the multiple guide rollers, the guide roller at the outermost end is the end guide roller 4, and an oil injection device is provided at the end guide roller 4. The oil injection device includes an oil tank adjustment assembly and an oil storage barrel 10. The oil injection device includes a base 5, a cylinder 6, an oil tank 7, and a felt 8. The base 5 is installed on the frame 1. A vertically extending kidney-shaped hole 9 is opened on the base 5. By passing a screw through the cylinder block of the cylinder 6 and the kidney-shaped hole 9 and tightening the nut, the installation of the cylinder 6 and the base 5 is realized. The vertical installation position of the base 5 can be adjusted through the kidney-shaped hole 9, so as to ensure the accuracy of the vertical position of the felt 8, and thus ensure the oiling quality of the inner frame paper 14. The cylinder 6 is installed on the base 5. The piston rod of the cylinder 6 extends upward and is connected to the bottom of the oil tank 7. The felt 8 is installed in the oil tank 7 through screws and extends upward from the open end at the top of the oil tank 7, and the felt 8 is located below the end guide roller 4. The oil tank 7 and the felt 8 are driven by the cylinder 6 to move vertically up and down, so as to drive the felt 8 to contact or separate from the inner frame paper 14 conveyed below the end guide roller 4; the oil storage barrel 10 is installed on the frame 1 and is located above one side of the oil tank 7. A fuel injection pipe 11 is provided at the bottom of the oil storage barrel 10, and a valve 12 is provided on the fuel injection pipe 11. The oil is injected into the oil tank 7 through the fuel injection pipe 11. The oil outlet end at the bottom of the fuel injection pipe 11 is retracted to form a conical oil outlet end 13.

[0018] A liquid level switch is provided in the oil tank 7, which can detect the liquid level in the oil tank 7 in real time, so as to be used as the basis for the opening and closing of the valve 12 on the fuel injection pipe 11, and ensure that the oil volume in the oil tank 7 always remains within a certain range.

[0019] For the inner frame paper oil injection device provided in this embodiment, when the device is working, the cylinder 6 drives the oil tank 7 to rise, so that the felt 8 is always in contact with the inner frame paper 14 to inject oil into the inner frame paper 14; when the device stops, the cylinder 6 drives the oil tank 7 to descend, so that the felt 8 is separated from the inner frame paper 14, avoiding excessive oil on the inner frame paper 14 due to too long contact time between the felt 8 and the inner frame paper 14, which affects subsequent packaging.

[0020] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
