Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of film cutting machine, concretely to a tension adjusting mechanism of film cutting machine. BACKGROUND

[0002] The film cutting machine is a kind of mechanical equipment that cuts wide paper, mica tape or film into multiple narrow materials, commonly used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. The main application of the cutting machine is: non-woven fabric, mica tape, paper, insulation materials and various film materials cutting, especially suitable for narrow tape (non-woven fabric, paper, insulation materials, mica tape, film, etc.).

[0003] When cutting plastic film, the tension between the films is very important. Most cutting machines will change tension after a long time of work, which will cause the films not to be in a tight state and affect the cutting effect, resulting in poor cutting effect.

[0004] The prior art with application number CN202221337462.9 proposes a plastic film cutting machine with tension adjusting mechanism. The specific working principle is that when the tension is relaxed and affects the cutting effect, the test plate will contact and press the control button at this time. At this time, the control button is connected with the cylinder through the wire to start the cylinder. The cylinder drives the rack to slide on the second mounting plate through the connecting plate. When the rack slides, the rack drives the gear to rotate, and the gear drives the second threaded rod to rotate. Through the rotation of the second threaded rod, the second threaded rod drives the adjusting frame to move upwards, and the adjusting frame drives the tension roller to move upwards, thereby achieving the effect of adjusting the tension between the plastic films. The above-mentioned plastic film cutting machine with tension adjusting mechanism cannot adjust the tension on one side when adjusting the tension. In actual use, when the tension on one side is relaxed, the adjusting frame will rise as a whole, which will cause the tension on the normal side to be too large. Therefore, the above-mentioned problem needs to be improved. SUMMARY

[0005] The purpose of this section is to outline some aspects of the embodiments of the present utility model and briefly introduce some preferred embodiments.

[0024] In order to make the above objects, features and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0025] In the following description, a lot of specific details are set forth in order to give a thorough understanding of the present application, but the present application can be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0027] In order to make the objects, technical schemes and advantages of the present application more clear, the embodiments of the present application will be described in further detail below in combination with the drawings.

[0028] The present application provides the following technical scheme: a tension adjusting mechanism of a film cutting machine, in the use process, through the spring installed at the top and bottom of the bearing block, the tension of the film body can be effectively reduced when the film body is subjected to the tension generated by conveying, and damage of the film body caused by excessive tension is prevented, when the pressure on both sides of the tension detection roller is too large, the tension detection roller on both sides applies pressure to the direction of the pressure sensor, when the pressure sensor detects that the pressure exceeds the preset value, the controller drives the electric telescopic rod to work, the electric telescopic rod rises to drive the tension adjusting roller to rise, the distance between the tension detection roller and the tension adjusting roller is adjusted, so as to reduce the tension of the film body, compared with the prior art, the device can be adjusted on one side, and the practicability is greatly improved.

[0029] Figures 1-4 The structure schematic diagram of the first embodiment of the tension adjusting mechanism of the film cutting machine of the present application is shown, please refer to Figures 1-4 The tension adjusting mechanism of the film cutting machine of the present application comprises a film cutting machine body 100.

[0030] The film cutting machine body 100 is provided with a tension adjusting assembly 200, which comprises a tension detection roller 210 and a tension adjusting roller 220.

[0031] The film cutting machine body 100 is provided with a tension adjusting assembly 200, which comprises a tension detection roller 210 and a tension adjusting roller 220.

[0032] The film cutting machine body 100 is provided with a tension adjusting assembly 200, which comprises a tension detection roller 210 and a tension adjusting roller 220.

[0033] The tension detection roller 210 is used for detecting the tension of the film body, which comprises a bearing frame 230, a spring 240 connected to the bottom of the bearing frame 230, a bearing block 250 for bearing the shaft rod 260, and a roller body 270 connected to the shaft rod 260. When the film body passes over the top of the tension detection roller 210, the roller body 270 will be pressed downward when the film body is subjected to tension. First, the spring 240 below the bearing block 250 absorbs the tension. When the pressure exceeds the absorption limit of the spring 240, the pressure sensor 280 detects that the pressure on the bearing frame 230 exceeds the preset value, and the controller controls the electric telescopic rod 290 to work, driving the tension adjusting roller 220 to rise, thereby reducing the tension of the film body. When the pressure sensor 280 detects that the pressure has recovered, the electric telescopic rod 290 drives the tension adjusting roller 220 to descend. When the film body is loose, the pressure on the tension detection roller 210 is 0, so the pressure on the pressure sensor is lower than the preset value. The controller controls the electric telescopic rod 290 to drive the tension adjusting roller 220 to move downward, so that the film body maintains a certain tension.

[0034] The tension adjusting roller 220 is used for adjusting its position when the pressure received by the tension detecting roller 210 exceeds the preset value, so as to reduce the tension received by the film body, which specifically comprises a bearing frame 230, a spring 240 arranged on the top of the bearing frame 230, which can preliminarily absorb the tension, a bearing block 250 used for bearing a shaft rod 260, the shaft rod 260 used for connecting a roller body 270, the roller body 270 used for conveying the film body, a pressure sensor 280 used for detecting the pressure received by the tension detecting roller 210, and an electric telescopic rod 290 used for driving the tension adjusting roller 220 to rise and fall;

[0035] The spring 240 mounted on the top and bottom of the bearing block 250 can effectively reduce the tension received by the film body when the film body receives the tension generated during conveying, so as to prevent the film body from being damaged due to the excessive tension. When the pressure on both sides of the tension detecting roller 210 is too large, the tension detecting roller 210 applies pressure to the pressure sensor 280. When the pressure sensor 280 detects that the pressure exceeds the preset value, the controller drives the electric telescopic rod 290 to work. When the electric telescopic rod 290 rises, the tension adjusting roller 220 rises, so as to adjust the distance between the tension detecting roller 210 and the tension adjusting roller 220, thereby reducing the tension received by the film body. Compared with the prior art, the device can be adjusted on one side, so as to greatly improve the practicability.

[0036] Although the present application has been described with reference to the embodiments above in the foregoing description, it is not intended to limit the present application to the above embodiments. Rather, various modifications made to the above embodiments and equivalents thereof within the scope of the present application are to be included. In particular, each feature introduced in the above description and each combination of two or more separate features can be realized by means of an arbitrary technical and / or non-technical measure, even if the feature or features are not explicitly described above in this respect.
