Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of film cutting machines, and in particular relates to a film pressing and cutting device for a tobacco silk thread film cutting machine. Background Art
[0002] In order to facilitate the storage and transportation of tobacco leaves, tobacco leaves are compressed into blocks to increase the packaging density, and in order to prevent slag from falling off during transportation and storage, a layer of plastic film is wrapped around the outside of the tobacco blocks. During the processing, the tobacco blocks need to be unpacked first, and then the plastic film is cut and removed by a film cutter before entering the next process. When the cutting machine cuts the film of the tobacco block, it first uses a pressing plate to press the film on both sides of the tobacco block onto the tobacco block, and then the cutter moves in a straight line to cut the film. Since the existing pressing plate is a flat smooth structure, when pressing the film, the film is relatively smooth and cannot be completely compressed. When cutting, the film is easy to move with the cutter, resulting in the problem that the film cannot be smoothly and completely cut off. Therefore, it is necessary to propose improvements. Utility Model Content
[0003] The technical problem solved by the utility model is to provide a film pressing and cutting device for a tobacco silk thread film cutting machine. The utility model aims to achieve complete pressing of the film by improving the pressure plate structure on the film cutting machine. The cutting knife will not move with the plastic film during cutting, thereby achieving complete and smooth cutting of the plastic film and facilitating subsequent film removal work.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] The film pressing and cutting device of the tobacco silk thread cutting machine comprises two gantries arranged front and back, a horizontally mounted longitudinal beam is connected between the middle parts of the columns on the same side of the two gantries, a horizontal cantilever cross frame is connected to the upper part of the horizontally mounted longitudinal beam, the horizontal cantilever cross frame is cantilevered toward the inner side of the gantry, a horizontal longitudinal bracket is arranged on the upper part of the horizontal cantilever cross frame, the horizontal longitudinal bracket can automatically move left and right along the horizontal transverse direction on the horizontal cantilever cross frame, a knife holder is arranged on the horizontal longitudinal bracket which automatically slides along the horizontal longitudinal direction, a cutting knife is fixed on the knife holder, the front side of the horizontal longitudinal bracket is connected to a pressing plate through a pressing plate bracket support, and a plurality of small pressing bumps are evenly arranged on the pressing surface of the front side of the pressing plate.
[0006] As a further limitation of the above solution, the small pressing bump is a small arc-shaped bump.
[0007] As a further limitation of the above solution, the small pressing bump is a small conical bump.
[0008] As a further limitation of the above scheme, the lower portion of the horizontal cantilever cross frame is connected to the horizontally installed longitudinal beam via a reinforcing rib plate.
[0009] To further define the above scheme, the automatic horizontal and transverse movement structure of the horizontal longitudinal bracket on the horizontal cantilever cross frame is as follows: a slideway is provided on the horizontal cantilever cross frame along the horizontal and transverse direction, a slider is provided at the lower part of the horizontal longitudinal bracket, the slider is slidably fitted together with the slideway, a driving cylinder is fixed to the rear part of the horizontal cantilever cross frame, and the piston rod of the driving cylinder is fixedly connected to the slider.
[0010] To further limit the above scheme, the implementation structure of the tool holder's automatic horizontal and longitudinal sliding on the horizontal longitudinal bracket is as follows: an electromagnetic cylinder is provided on the upper part of the horizontal longitudinal bracket, a tool holder moving block is fixedly connected to the electromagnetic cylinder, and the tool holder is placed in front of the electromagnetic cylinder and fixedly connected to the tool holder moving block.
[0011] The advantages of this utility model compared with the prior art:
[0012] 1. In this scheme, the structure of the pressing plate on the film cutting machine is improved, and a plurality of small pressing protrusions are evenly distributed on the pressing surface of the pressing plate. In the process of pressing the outer film of the cigarette block, the small pressing protrusions can be embedded in the cigarette block along the plastic film, thereby achieving complete pressing of the film, and the cutting knife will not move with the plastic film during cutting, thereby achieving complete and smooth cutting of the plastic film, which is convenient for the subsequent film removal work;
[0013] 2. In this solution, the small pressing bumps on the pressing plate are made into arc-shaped or conical-shaped small bumps, which not only facilitates pressing the plastic film into the cigarette block to achieve pressing, but also prevents the plastic film from being crushed, thereby preventing the subsequent pressing plate from being unable to smoothly detach from the film.
