Description

Technical Field

[0001] The utility model relates to the technical field of film production, in particular to a static-eliminating roller structure for film production. Background Art

[0002] Medical film is an important imaging tool in the medical field. Static electricity will be generated due to friction during the production, transportation and collection of medical films. The static electricity generated will not only cause harm to the workers' health, but also bring hidden dangers to production. During the production process, the film will inevitably be charged due to friction with the production equipment and the film. The voltage on the film can reach 2000 volts, which will pose a safety hazard to production.

[0003] Medical film plays a vital role in the diagnosis process, and its image quality directly affects the accuracy of doctors' diagnosis. Static electricity can cause gray fog, dendritic, star-shaped or non-positioned static electricity on medical films, which will affect the image quality of the film and further affect the doctor's diagnosis, so it is necessary to eliminate the static electricity on the medical film. At present, most of the static electricity elimination devices for medical films are for single-side static electricity elimination. However, static electricity will be generated on both sides of medical films during the friction process of falling, pressing, etc. during transportation, so static electricity elimination is required for both sides of medical films.

[0013] 1. The medical film can first pass through the lower surface of the adjusting roller on one side, then pass through the upper surface of the main roller, and finally bypass the lower surface of the adjusting roller on the other side. When the tension spring can drive the sliding column to slide down on the support plate all the time, the connecting block will drive the conductive rod to press down, so that the multiple metal balls on the lower surface of the conductive rod can contact the top surface of the medical film. The metal balls can absorb the static electricity on the upper surface of the medical film and transmit it to the conductive ring, and then conduct it to the ground through the copper column, so it helps to eliminate the static electricity on the top surface of the medical film. By passing the medical tape through the bottom of the two adjusting rollers, and the bottom of the adjusting roller is provided with an arc-shaped static Brush plate, so that when the medical tape passes through the adjustment roller, when the tip of the eliminator in the arc-shaped static electricity brush plate approaches the charged body, it induces a charge with a polarity opposite to the electrostatic polarity on the charged body, thereby neutralizing the static electricity, so that the static electricity on the bottom surface of the medical film can be completely eliminated. Therefore, through this roller structure, the static electricity on both sides of the film can be eliminated synchronously, so as to ensure that the film will not affect the doctor's diagnosis when used. The rotation of the rotating column can make the bevel gear one and the bevel gear two mesh and rotate, and then the lifting screw rod is driven to rise and fall through the internal threaded cylinder, so that the distance between the arc-shaped static electricity brush plate and the adjustment roller can be adjusted, so it is convenient to adjust according to the thickness of the film.

[0014] 2. The worm can be driven to rotate by the rotary handle, so that the worm can drive the worm wheels on both sides to rotate in opposite directions, so that the two positioning shafts can drive their respective adjustment arms to rotate in opposite directions. The height positions of the two adjustment rollers can be adjusted by the ends of the adjustment arms, so as to facilitate the adjustment of the conveying tension of the medical film, thereby ensuring the transmission effect of the medical film, avoiding the problem of film slippage during conveying, and also ensuring the double-sided static electricity elimination effect of the film.

Detailed implementation manner

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 6 , in the embodiment of the present invention, an electrostatic removal roller structure for film production includes two support plates 101. A main roller 102 is rotatably connected between the two support plates 101. A base plate 201 is fixedly connected between the bottoms of the two support plates 101. Two sliding columns 103 are symmetrically and slidably connected to the tops of the two support plates 101. A connecting block 104 is fixedly connected between the tops of the two sliding columns 103. A conductive rod 106 is fixedly connected between the two connecting blocks 104. A plurality of metal balls 107 are movably connected to the bottom of the conductive rod 106 at equal intervals. A tension spring 105 fixedly connected to the connecting block 104 is sleeved outside the sliding column 103; One end of a copper column 109 is fixedly sleeved at the end of the conductive rod 106, and the other end of the copper column 109 is grounded.

[0024] Specifically, the medical film can first pass through from the lower surface of the adjusting roller 210 on one side, then pass through from the upper surface of the main roller 102, and finally pass around from the lower surface of the adjusting roller 210 on the other side. When the tension spring 105 can drive the sliding column 103 to always slide downward on the support plate 101, the connecting block 104 will drive the conductive rod 106 to press downward, so that the multiple metal balls 107 on the lower surface of the conductive rod 106 can contact the top surface of the medical film. The metal balls 107 can absorb the static electricity on the upper surface of the medical film and transmit it to the conductive ring 108, and then conduct it to the ground through the copper column 109. Therefore, it helps to eliminate the static electricity on the top surface of the medical film. Embodiment 1

[0025] As Figure 6 shown, in this embodiment, two limiting grooves 202 are symmetrically formed on the base plate 201. Limiting blocks 214 are symmetrically and slidably embedded in the two limiting grooves 202. The top ends of the limiting blocks 214 are fixedly connected with a sliding plate 212. A sleeve rod 211 is slidably sleeved outside the sliding plate 212. A connecting shaft 209 is rotatably connected between the two opposite sleeve rods 211. An adjusting roller 210 is fixedly sleeved outside the connecting shaft 209. A connecting plate 213 is fixedly connected between the bottom ends of the two sliding plates 212; A rotating column 215 is rotatably connected to the sliding plate 212. The end of the rotating column 215 is fixedly connected with a first bevel gear 216. A second bevel gear 217 is meshed and connected to one side of the first bevel gear 216. An internal thread cylinder 218 is fixedly connected to the central position of the second bevel gear 217. A lifting screw rod 219 is screwed and sleeved in the internal thread cylinder 218. The top end of the lifting screw rod 219 is fixedly connected with an arc-shaped static electricity brush plate 221. An L-shaped plate 220 fixedly connected to the connecting plate 213 is rotatably sleeved outside the internal thread cylinder 218. A telescopic column 222 fixedly connected to the bottom of the arc-shaped static electricity brush plate 221 is fixedly connected to the connecting plate 213.

[0026] In this embodiment, by passing the medical tape through the bottom of the two adjusting rollers 210, and an arc-shaped static electricity brush plate 221 is arranged at the bottom of the adjusting roller 210. When the medical tape passes through the adjusting roller 210, when the tip of the static eliminator in the arc-shaped static electricity brush plate 221 approaches the charged body, charges with opposite polarities to the static charges on the charged body are induced, thereby neutralizing the static electricity. Thus, all the static electricity on the bottom surface of the medical film can be eliminated. Therefore, through this roller structure, the static electricity elimination work on both sides of the film can be carried out synchronously, so as to ensure that the film will not affect the doctor's diagnosis during use. By rotating the rotating column 215, the first bevel gear 216 and the second bevel gear 217 can be meshed and rotated, and then the lifting screw rod 219 can be driven by the internal thread cylinder 218 to lift and lower, so as to adjust the distance between the arc-shaped static electricity brush plate 221 and the adjusting roller 210. Therefore, it is convenient to adjust according to the thickness of the film. Embodiment 2

[0028] During specific implementation, the worm 204 can be driven to rotate by the rotary handle 205, so that the worm 204 can drive the worm wheels 206 on both sides to rotate in opposite directions, so that the two positioning shafts 207 can drive their respective adjustment arms 208 to rotate in opposite directions, and the height positions of the two adjustment rollers 210 can be adjusted by the ends of the adjustment arms 208, so as to facilitate the adjustment of the conveying tension of the medical film, thereby ensuring the transmission effect of the medical film, avoiding the problem of film slippage during conveying, and also ensuring the double-sided static electricity elimination effect of the film.
