This utility model discloses a thickness measuring device for a winding tape, relating to the field of materials science and technology. The utility model includes a base and four support columns fixedly connected to the outer surface of the base. A thickness measuring box is fixedly connected to the top of the four support columns. The inner wall of the thickness measuring box is provided with an adjustment mechanism. The top of the base is provided with a tape pressing mechanism. This utility model incorporates a movable frame. The rotation of two small gears causes the rack to move, which in turn drives the two movable frames to move closer to each other.

Description

Technical Field

[0001] This utility model belongs to the field of materials science and technology, and in particular relates to a device for measuring the thickness of a winding tape. Background Technology

[0002] Stretch wrap is a type of tape used for binding, securing, or protecting items. It is typically made of plastic, metal, or other flexible materials and can be used in various fields such as packaging, transportation, and storage to help maintain the stability and integrity of items. Stretch wrap thickness measuring devices are equipment used to measure the thickness of stretch wrap. These devices are mainly used in packaging, manufacturing, or other industrial fields to ensure that the thickness of the stretch wrap meets standard requirements.

[0003] Existing wrapping tape thickness measuring devices typically clamp the wrapping tape and then test its thickness. This method may introduce errors due to the clamping of the wrapping tape. If the wrapping tape could be placed between two rollers, and the thickness of the wrapping tape could be measured by the displacement change of the rollers when the wrapping tape is adapted to the rollers, it would be more accurate. Therefore, we propose a wrapping tape thickness measuring device. Utility Model Content

[0004] The purpose of this utility model is to provide a device for measuring the thickness of a winding tape. The rotation of the pinion (205) causes the rack (204) to move, and then the rack (204) drives the two moving frames (203) to move towards each other. At this time, the moving frames (203) drive the first roller (217) to gradually approach the winding tape, thus solving the problem of measuring the thickness of the winding tape by changing the displacement of the roller.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a device for measuring the thickness of a winding tape, including a base and four support columns fixedly connected to the outer surface of the base. A thickness measuring box is fixedly connected to the top of the four support columns. The inner wall of the thickness measuring box is provided with an adjustment mechanism. The top of the base is provided with a tape pressing mechanism. The adjustment mechanism includes two connecting plates fixedly connected to the inner wall of the thickness measuring box. A laser displacement sensor is fixedly connected to the inner wall of each of the two connecting plates. Two movable frames are provided inside the thickness measuring box. The output end of the laser displacement sensor corresponds to the outer surface of the two movable frames respectively. A first roller is rotatably connected to the inner wall of each of the two movable frames. Two racks are fixedly connected to one side of each of the two movable frames. A pinion is meshed on the outer surface of each of the two racks. A display screen is fixedly connected to one side of the thickness measuring box. A driving component is provided on the other side of the thickness measuring box for rotating the pinion.

[0006] Furthermore, the driving component includes a motor housing and a motor fixedly connected to the other side of the thickness measuring box. The motor is located inside the motor housing, and the output shaft of the motor is fixedly connected to a rotating shaft via a coupling. One end of the rotating shaft penetrates the outer surface of the thickness measuring box.

[0007] Furthermore, the outer surface of the rotating shaft is fixedly connected to the inner wall of the small gear, and a first large gear is fixedly connected to the outer surface of the rotating shaft. The first large gear is disposed inside the thickness measuring box, and a second large gear meshes with the bottom of the first large gear. A driven shaft is fixedly connected to the inner wall of the second large gear, and the outer surface of the driven shaft is fixedly connected to the inner wall of the small gear.

[0008] Furthermore, two limiting rings are fixedly connected to the outer surfaces of the driven shaft and the rotating shaft, and the outer surfaces of the two limiting rings are rotatably connected to the inner wall of the thickness measuring box.

[0009] Furthermore, two connecting blocks are fixedly connected to the other side of each of the two movable frames, and limit rods are slidably connected to the inner walls of the two connecting blocks. The top and bottom of the limit rods are fixedly connected to the outer surfaces of the two connecting plates, and two limit cylinders are fixedly connected to the outer surfaces of the two connecting plates. The inner sides of the two limit cylinders are sleeved with the outer surfaces of the limit rods.

[0010] Furthermore, the pressing mechanism includes two wrapping shells fixedly connected to the top of the base. Two first connecting strips and two second connecting strips are fixedly connected to the side of the two wrapping shells near the thickness measuring box, respectively. The two first connecting strips are all arranged above the two second connecting strips. A pressing shell is fixedly connected between the two first connecting strips and the two second connecting strips. A movable frame is provided inside the pressing shell. Two pressure rollers are rotatably connected to the inner wall of the movable frame. Four sliding rods are fixedly connected to the side of the movable frame away from the pressure rollers. The outer surfaces of the four sliding rods are slidably connected to the inner wall of the pressing shell. Four springs are fixedly connected between the outer surface of the movable frame and the inner wall of the pressing shell. The inner sides of the four springs are respectively sleeved on the outer surfaces of the four sliding rods. A limit plate is fixedly connected to one end of the four sliding rods.

[0011] Furthermore, the inner walls of the two winding shells are respectively fixedly connected to connecting shafts, and electric rollers are rotatably connected to the outer surfaces of the connecting shafts.

[0012] Furthermore, driven bars are fixedly connected to both sides of the movable frame, and two fixed rods are slidably connected to the inner wall of the driven bars, with the two ends of the two fixed rods fixedly connected to the inner wall of the pressure belt shell.

[0013] This utility model has the following beneficial effects: 1. This utility model incorporates a movable frame. The rotation of the two small gears causes the rack to move, which in turn drives the two movable frames to move closer to each other. At this time, the movable frames also cause the connecting block to slide along the limiting rod, allowing the first roller to gradually approach the winding tape. When the winding tape is just able to drive the first roller to rotate, the motor stops. During this process, the laser displacement sensor continuously emits a laser beam onto the movable frame. Through the rack that can drive the movable frame to move, the thickness of the winding tape can be measured by the displacement change of the movable frame.

[0014] 2. This utility model incorporates a movable frame. The winding tape pushes the pressure roller, which in turn rotates the pressure roller. The pressure roller then pushes the movable frame, which in turn causes the driven strips on both sides to slide along the fixed rod. The movable frame then pushes the limiting plate via the sliding rod and compresses the spring. The spring's return pushes the movable frame. By using a spring that can push the movable frame, the swaying of the winding tape during continuous movement is reduced, thus minimizing its impact on test data.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-8 As shown, this utility model is a winding tape thickness measuring device, including a base 101 and four support columns 102 fixedly connected to the outer surface of the base 101. A thickness measuring box 103 is fixedly connected to the top of the four support columns 102. An adjustment mechanism 2 is provided on the inner wall of the thickness measuring box 103. A tape pressing mechanism 3 is provided on the top of the base 101. This device can be adjusted in the thickness measuring box 103 by the adjustment mechanism 2, and then the thickness of the winding tape can be measured by displacement. At the same time, the movement of the winding tape can be stabilized by the tape pressing mechanism 3. The adjustment mechanism 2 includes two connecting plates 201 fixedly connected to the inner wall of the thickness measuring box 103. A laser displacement sensor 202 is fixedly connected to the inner wall of each of the two connecting plates 201. Two movable frames 203 are provided inside the thickness measuring box 103. The output end of the laser displacement sensor 202 corresponds to the outer surface of the two movable frames 203 respectively. The movable frames 203 will move inside the thickness measuring box 103. At this time, the laser displacement sensor 202 will measure the movement of the movable frames 203. The thickness of the winding tape is measured by the distance moved by the movable frames 203. The inner walls of the two movable frames 203 are respectively rotatably connected to the first roller 217. Two racks 204 are fixedly connected to one side of each of the two movable frames 203. Two racks 204 have pinions 205 meshing on their outer surfaces. The pinions 205 can rotate, which causes the racks 204 to move. The racks 204 then drive the moving frame 203 to move. A display screen 206 is fixedly connected to one side of the thickness measuring box 103, and a drive unit is provided on the other side of the thickness measuring box 103 for rotating the pinions 205. The data measured by the laser displacement sensor 202 is reflected on the display screen 206 in real time, and the data can be observed and recorded through the display screen 206.

[0021] The driving components include a motor housing 207 and a motor 208 fixedly connected to the other side of the thickness measuring box 103. The motor 208 is located inside the motor housing 207. The output shaft of the motor 208 is fixedly connected to a rotating shaft 209 via a coupling. One end of the rotating shaft 209 passes through the outer surface of the thickness measuring box 103. The motor 208 causes the rotating shaft 209 to rotate. At this time, the rotating shaft 209 drives the pinion 205 to rotate, thereby allowing the pinion 205 to perform the next transmission step.

[0022] The outer surface of the rotating shaft 209 is fixedly connected to the inner wall of the pinion 205. A first large gear 210 is fixedly connected to the outer surface of the rotating shaft 209. The first large gear 210 is located inside the thickness measuring box 103. The rotating shaft 209 will also drive the first large gear 210 to rotate. Then the first large gear 210 can carry out the next transmission. A second large gear 211 is meshed at the bottom of the first large gear 210. A driven shaft 212 is fixedly connected to the inner wall of the second large gear 211. The outer surface of the driven shaft 212 is fixedly connected to the inner wall of the pinion 205. The first large gear 210 will drive the second large gear 211 to rotate. At this time, the second large gear 211 will drive the driven shaft 212 to rotate. Then the driven shaft 212 will also drive the pinion 205 to rotate, thereby making the movement of the moving frame 203 more stable.

[0023] Two limiting rings 213 are fixedly connected to the outer surfaces of the driven shaft 212 and the rotating shaft 209, respectively. The outer surfaces of the two limiting rings 213 are rotatably connected to the inner wall of the thickness measuring box 103. Both the driven shaft 212 and the rotating shaft 209 will drive the limiting rings 213 to rotate inside the thickness measuring box 103. At this time, the limiting rings 213 play a limiting role, making the rotation of the rotating shaft 209 and the driven shaft 212 more stable.

[0024] Two connecting blocks 214 are fixedly connected to the other side of each of the two movable frames 203. Limiting rods 215 are slidably connected to the inner walls of the two connecting blocks 214. The top and bottom of the limiting rods 215 are fixedly connected to the outer surfaces of the two connecting plates 201. The movable frame 203 will drive the connecting blocks 214 to slide along the limiting rods 215. At this time, the connecting blocks 214 play a limiting role, making the movement of the movable frame 203 more stable. Two limiting cylinders 216 are fixedly connected to the outer surfaces of the two connecting plates 201. The inner sides of the two limiting cylinders 216 are sleeved on the outer surfaces of the limiting rods 215. The limiting cylinders 216 restrict the movement of the movable frame 203, preventing the outer surface of the movable frame 203 from getting too close to the output end of the laser displacement sensor 202, and preventing the measurement deviation of the laser displacement sensor 202.

[0025] The tape pressing mechanism 3 includes two tape winding shells 301 fixedly connected to the top of the base 101. Two first connecting strips 302 and two second connecting strips 303 are fixedly connected to the side of the two tape winding shells 301 near the thickness measuring box 103, respectively. The two first connecting strips 302 are all arranged above the two second connecting strips 303. The tape winding shells 301 provide a certain support for the first connecting strips 302 and the second connecting strips 303, so that the device can work more stably. A tape pressing shell 304 is fixedly connected between the two first connecting strips 302 and the two second connecting strips 303. A movable frame 305 is provided inside the tape pressing shell 304. Two pressure rollers 306 are rotatably connected to the inner wall of the movable frame 305. Four sliding rods 307 are fixedly connected to the side of the movable frame 305 away from the pressure rollers 306. The pressure rollers 306 will press the winding tape tightly to reduce the shaking of the winding tape during the movement, thereby reducing the impact of shaking on the measurement results. The outer surfaces of the four slide rods 307 are slidably connected to the inner wall of the pressure plate shell 304. Four springs 308 are fixedly connected between the outer surface of the moving frame 305 and the inner wall of the pressure plate shell 304. The inner sides of the four springs 308 are respectively sleeved on the outer surfaces of the four slide rods 307. A limit plate 309 is fixedly connected to one end of the four slide rods 307. The slide rods 307 restrict the movement of the springs 308, so that the springs 308 can only move along the slide rods 307, preventing the springs 308 from tilting or deviating during the movement.

[0026] Two winding housings 301 are respectively fixedly connected to the inner walls of the two winding housings 301. Electric rollers 311 are rotatably connected to the outer surfaces of the connecting shafts 310. The winding tape can be wound onto the two electric rollers 311. At this time, the winding tape can drive the electric rollers 311 to rotate, thereby assisting in the measurement.

[0027] The movable frame 305 is fixedly connected to two sides by driven bars 312. Two fixed rods 313 are slidably connected to the inner wall of the driven bars 312. The two fixed rods 313 are fixedly connected to the inner wall of the pressure plate shell 304 at both ends. The movable frame 305 will drive the driven bars 312 to slide along the fixed rods 313. At this time, the driven bars 312 play a stabilizing role to prevent the movable frame 305 from deviating during the movement.

[0028] One specific application of this embodiment is: When the staff needs to use the equipment, first wrap the winding tape around the electric roller 311, and then start the electric roller 311. At this time, the electric rollers 311 at both ends will make the winding tape move continuously along the electric roller 311. During the movement of the winding tape, since the winding tape itself has a certain thickness, the winding tape will push the pressure roller 306. At the same time, the winding tape will also drive the pressure roller 306 to rotate. Then the pressure roller 306 will push the moving frame 305. At the same time, the moving frame 305 will also drive the driven bars 312 on both sides to slide along the fixed rod 313. Then the moving frame 305 will push the limiting plate 309 through the slide rod 307. At the same time, the moving frame 305 will also squeeze the spring 308. Then, the reset of spring 308 will push the moving frame 305, causing the pressure roller 306 to clamp the winding tape, which can reduce the shaking of the winding tape during continuous movement and reduce the impact on test data. At this time, the initial state of the connecting block 214 is in contact with the limit cylinder 216, and the motor 208 can be started. At this time, the motor 208 will cause the rotating shaft 209 to rotate. Then the rotating shaft 209 will drive the first large gear 210 to rotate. Then the first large gear 210 will drive the driven shaft 212 to rotate through the second large gear 211. At this time, the rotating shaft 209 and the driven shaft 212 will simultaneously drive the two small gears 205 to rotate. Then the rotation of the two small gears 205 will cause the rack 204 to move. Then the rack 204 will drive the two moving frames 203 to move closer to each other. At this time, the moving frames 203 will also drive the connecting block 214 to slide along the limit rod 215, so that the first roller 217 gradually approaches the winding tape. When the winding tape can just drive the first roller 217 to rotate, the motor 208 stops. During this process, the laser displacement sensor 202 will continuously emit a laser beam to the moving frame 203 and measure the reflected light signal to calculate the distance moved by the moving frame 203. Finally, the measurement result is displayed on the display screen 206, achieving the effect of measuring the thickness of the winding tape by the displacement change of the moving frame 203.
