Embodiment approach

[0053] Such as image 3 As shown, according to an embodiment of the present invention, the tension sensor is connected to the film pulling module through a connecting screw 210 , the connecting screw 210 passes through the sensor 200 vertically, and is connected to the screw 510 inside the sensor. The connecting screw 210 is provided with a nut 220 above the film pulling module.

[0054] Such as Figure 4 As shown, there is a hole 2101 in the middle of the connecting screw 210 , and the screw 510 passes through the hole 2101 on the connecting screw and is connected to the film stretching module 100 .

[0055]With the above-mentioned design, the connecting screw 210 can rotate in the horizontal direction relative to the film-drawing module. While the film-drawing module moves along the direction of the screw through the telescopic module, it can also rotate to a certain extent relative to the screw and the sensor, that is, tension is generated along the direction of the screw....

Embodiment

[0076] This embodiment provides a controllable tension film pulling device, such as figure 1 As shown, it mainly includes a film pulling module 100 , a tension sensor 200 , a digital display module 300 , an optical platform 400 , and a telescopic module 500 ; The film is placed between the base 110 and the pressing block 120, and the pressing block 120 is tightly pressed onto the base 110 using the quick clamp 130 to fix the film; one end of the tension sensor 200 is connected to the film pulling module 100, and the other end is connected to the telescopic screw 510 , the telescopic screw 510 drives the tension sensor 200 and the film pulling module to move backward under the tightening of the nut 520, thereby making the film tense, and at the same time, the tension value applied to the film is displayed by the digital display module 300 of the tension sensor; by adjusting The numerical value on the digital display module 300 connected with the nut 520 and the tension sensor 2...

Abstract

The invention relates to a tension-controllable film drawing device which is characterized by comprising a film drawing module, a tension sensor and a telescopic module, and the film drawing module isused for clamping and fixing a film; the telescopic module comprises a screw rod, a nut and a fixing block, the screw rod penetrates through the fixing block and can move forwards and backwards in the axial direction relative to the fixing block, the screw rod is fixedly connected with the tension sensor in one side of the fixing block, and the screw rod is in threaded connection with the nut inthe other side of the fixing block; and the tension sensor is connected with the film drawing module. Tension control over the thin film can be conveniently achieved, multiple sets of film drawing combinations can be further applied in different directions of the thin film, and the tension of the thin film is uniform.

Description

technical field [0001] The invention relates to the technical field of film stretching, in particular to a film stretching device with controllable tension. Background technique [0002] Nuclear radiation detectors are components that detect nuclear radiation by using the ionization effect, luminescence, physical or chemical changes caused by nuclear radiation in gas, liquid or solid. Charged particles interact with the medium as they pass through it, losing some of their energy through excitation of bound electrons in atoms or ionization. In general, excitation occurs at lower energies of charged particles, and ionization plays a major role at higher energies. The ionization process refers to the incident particles in the medium, through scattering, transfer part of the energy to the electrons in the atoms, so that the electrons are directly detached from the nucleus to form electron-ion pairs. Nuclear radiation detectors can directly or indirectly determine the type, ene...
