Description

Technical Field

[0001] The utility model relates to the technical field related to the production of thermal films, in particular to a thermal film anti-static roller. Background Art

[0002] Thermal film uses a blue polyester base, with a photosensitive emulsion coated on the front and an anti-halation layer coated on the back. The film has rich layers and good clarity. The film is suitable for different medical images. Such as: tomograms, digital subtraction, ultrasonic imaging, etc. During the production process, thermal film needs to be conveyed by guide rollers. When the guide rollers convey the materials, static electricity will be generated on the surface of the materials due to friction. The existence of static electricity will affect the subsequent production process and product quality. At the same time, there are safety hazards, that is, static electricity has a great impact on the production of thermal film. Therefore, it is necessary to remove static electricity from the surface of the thermal film. In the prior art, static electricity is often eliminated by a guide roller or a brush grounded by a wire. The brush has a higher static electricity conduction capacity than the guide roller, but the brush does not have the effect that the guide roller can rotate, which will increase the friction during the film conveying process.

[0003] Therefore, we propose a heat-sensitive film anti-static roller to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a heat-sensitive film static-eliminating roller.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A heat-sensitive film anti-static roller comprises a center roller, a hollow roller sleeve, a conductive inner cylinder and two insulating fixed seats; the hollow roller sleeve is sealingly and rotatably sleeved on the center roller, and the two insulating fixed seats are respectively fixedly connected to the two ends of the center roller, a plurality of sieve holes are evenly arranged on the hollow roller sleeve, a plurality of bristles are evenly arranged on the surface of the conductive inner cylinder, and the plurality of bristles extend to the outside of the hollow roller sleeve through the sieve holes, the conductive inner cylinder is rotatably sleeved on the center roller and coaxially and fixedly connected with the hollow roller sleeve, and the conductive inner cylinder is electrically connected to a grounding wire, one end of which passes through the center roller and is grounded.

[0007] Preferably, the bristles are made of superconducting carbon fiber material.

[0008] Preferably, the center roller is made of hard insulating plastic material.

[0009] Preferably, a bearing structure is installed between the hollow roller sleeve and the two insulating fixing seats.

[0010] Preferably, the conductive inner cylinder is configured as a metal fixed cylinder fixedly mounted on the center roller and a metal mesh cylinder rotatably mounted on the metal fixed cylinder, the metal mesh cylinder is coaxially fixedly connected to the hollow roller sleeve, a plurality of the bristles are fixedly mounted on the metal mesh cylinder, and the grounding wire is electrically connected to the metal fixed cylinder.

[0011] Preferably, the hollow roller sleeve is made of insulating heat-conductive plastic material.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the roller can remove static electricity on the thermal film during the process of conveying the thermal film, wherein the bristles contact the thermal film to absorb static electricity, and then transfer the static electricity to the conductive inner cylinder, which is grounded by a wire to remove static electricity, thereby realizing the static electricity removal function, and the static electricity removal structure is arranged on the guide roller, without the need to additionally arrange a static electricity removal structure, thereby simplifying the equipment structure; the second phase cooperates with the bristle structure, and has a higher effect on the absorption and removal of static electricity. At the same time, due to the arrangement of the guide roller, a large friction with the thermal film is avoided, and the thermal film can be cleaned to a certain extent while removing static electricity.

A number of sieve holes are evenly arranged on the hollow roller sleeve 2, and a number of bristles 5 are evenly arranged on the surface of the conductive inner cylinder 3, and the bristles 5 extend to the outside of the hollow roller sleeve 2 through the sieve holes, and the bristles 5 contact the thermal film to absorb static electricity.

[0020] In some embodiments, the bristles 5 are made of superconducting carbon fiber material to fully ensure the effects of electrostatic adsorption and conduction, and the texture is made soft to avoid damaging the thermal film. The center roller 1 is made of hard insulating plastic material to avoid static electricity being affected by the conduction of the center roller 1, thereby ensuring the overall static electricity removal effect. The hollow roller sleeve 2 is made of insulating thermal conductive plastic material, which can also play a certain role in heat conduction cooling for the thermal film.
