Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental floss production technology, specifically to a dental floss stick testing device for dental floss abrasion resistance. Background Technology
[0002] Among the various quality indicators in dental floss production, abrasion resistance is one of the key factors. Dental floss needs to rub against the tooth surface between teeth during use. If its abrasion resistance is poor, the floss is prone to breakage, failing to achieve a good cleaning effect and negatively impacting the user experience.
[0003] Currently, the traditional method for testing the abrasion resistance of dental floss usually relies on manual simulation of dental floss use for simple tests. This method is not only prone to hand fatigue, but also lacks accuracy due to the variability in manual operation. Utility Model Content
[0004] The purpose of this invention is to design a dental floss abrasion testing device for dental floss sticks, so as to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A dental floss abrasion testing device for dental floss picks includes a support plate, a side plate on one side of the support plate, a sliding hole in the middle of the side plate, a sliding rod slidably fitted in the sliding hole, a drive mechanism on the support plate for reciprocating motion of the sliding rod, a vertical plate connected to the end of the sliding rod away from the drive mechanism, two opposing clamping mechanisms on the side of the vertical plate away from the sliding rod, dental floss clamped between the two clamping mechanisms, two support rods connected to the side plate, abrasion-resistant heads connected to the sides of the two support rods that are close to each other, the clamping mechanism being located between the side plate and the abrasion-resistant heads, the gap between the two abrasion-resistant heads being smaller than the diameter of the dental floss and aligned with the dental floss.
[0007] Furthermore, the driving mechanism includes a motor and a turntable. The motor is fixed to the side of the side plate, and the output end of the motor passes through the side plate and is fixedly connected to the turntable. A push rod is rotatably connected to the turntable near its edge, and a connecting block is rotatably connected to the other end of the push rod. The end of the slide rod away from the vertical plate is fixedly connected to the connecting block.
[0008] Furthermore, a bearing is fixedly connected inside the side plate, and the output end of the motor is fixedly connected to the inner ring of the bearing.
[0009] Furthermore, the clamping mechanism includes a clamping block and a clamping plate. The clamping block is fixedly connected to the vertical plate. The clamping block is provided with two symmetrically arranged limiting holes. Each of the two limiting holes is slidably fitted with a limiting rod. One end of each limiting rod is fixedly connected to the clamping plate, and the other end is fixedly connected through a connecting plate. The connecting plate is provided with a first screw hole. A screw rod is threaded into the first screw hole. One end of the screw rod is rotatably connected to the clamping block, and the other end is fixedly connected to a rotating handle.
[0010] Furthermore, the clamping block has an arc-shaped limiting groove on the side near the clamping plate.
[0011] Furthermore, the clamping plate is provided with an anti-slip rubber pad on the side near the clamping block.
[0012] Furthermore, each of the two wear-resistant heads is fixedly connected to an adjusting rod on the side away from each other. The supporting rod is provided with an adjusting hole that slides with the adjusting rod. The top of the supporting rod is provided with a second threaded hole that communicates with the adjusting hole. An adjusting bolt is threaded into the second threaded hole.
[0013] Furthermore, the lower part of the support plate is fixedly connected to a support foot, which is fixed to the workbench by screws.
[0014] The beneficial effects of this utility model are as follows:
[0015] By fixing the dental floss to be tested between two clamping mechanisms, the drive mechanism drives the slide bar to reciprocate. The slide bar drives the clamping mechanism through the vertical plate, thereby causing the dental floss to repeatedly pass through the gap between the two abrasion-resistant heads. This causes the dental floss to rub against the surface of the abrasion-resistant heads multiple times. After the drive mechanism has reciprocated a certain number of times, it stops. If the dental floss does not break, the dental floss is considered to have passed the test. This testing method not only prevents hand fatigue but also greatly reduces operational variability and improves the accuracy of the test results. Attached Figure Description

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0025] like Figure 1-5As shown, a dental floss abrasion testing device for dental floss picks includes a support plate 1, a side plate 2 on one side of the support plate 1, a sliding hole 3 in the middle of the side plate 2, a sliding rod 4 slidably fitted in the sliding hole 3, a drive mechanism on the support plate 1 to drive the sliding rod 4 to reciprocate, a vertical plate 5 connected to the end of the sliding rod 4 away from the drive mechanism, two opposing clamping mechanisms on the side of the vertical plate 5 away from the sliding rod 4, and dental floss 28 clamped between the two clamping mechanisms. The drive mechanism drives the sliding rod 4 to reciprocate, and the sliding rod 4 drives the clamping mechanism to move through the vertical plate 5, thereby driving the dental floss 28 to reciprocate, thus replacing manual operation of the dental floss 28 and preventing hand fatigue; the side plate 2 is connected to... Two support rods 6 are connected to wear-resistant heads 7 on their adjacent sides. The wear-resistant heads 7 are made of a wear-resistant material similar to the surface of teeth, and their surface shape is designed to match the curvature of the tooth surface to improve the authenticity of the dental floss 28 test. The clamping mechanism is located between the side plate 2 and the wear-resistant heads 7. The gap between the two wear-resistant heads 7 is smaller than the diameter of the dental floss 28 and is aligned with the dental floss 28. The dental floss 28 reciprocates, allowing it to pass through the gap between the two wear-resistant heads 7 multiple times, so that the dental floss 28 rubs against the surface of the wear-resistant heads 7 multiple times to perform wear resistance testing on the dental floss. The lower part of the support plate 1 is fixedly connected to the support foot 27, which is fixed to the worktable by screws.
[0026] The drive mechanism includes a motor 8 and a turntable 9. The motor 8 is fixed to the side of the side plate 2, and the output end of the motor 8 passes through the side plate 2 and is fixedly connected to the turntable 9. The motor 8 drives the turntable 9 to rotate. A bearing 12 is fixedly connected inside the side plate 2, and the output end of the motor 8 is fixedly connected to the inner ring of the bearing 12. The bearing 12 can improve the stability of the output end of the motor 8 during rotation. A push rod 10 is rotatably connected to the turntable 9 near its edge. The other end of the push rod 10 is rotatably connected to a connecting block 11. The end of the slide rod 4 away from the vertical plate 5 is fixedly connected to the connecting block 11. When the turntable 9 rotates, the push rod 10 can push the slide rod 4 to reciprocate within the sliding hole 3. The motor 8 is also electrically connected to a controller, which can set the number of times the output end of the motor 8 rotates, thereby controlling the number of times the slide rod 4 reciprocates.
[0027] The clamping mechanism includes a clamping block 13 and a clamping plate 14. The clamping block 13 is fixedly connected to the vertical plate 5. The clamping block 13 has two symmetrically arranged limiting holes 15. Each limiting hole 15 has a limiting rod 16 that slides within it. One end of each limiting rod 16 is fixedly connected to the clamping plate 14, and the other end is fixedly connected to a connecting plate 17. The connecting plate 17 has a first screw hole 18, and a screw 19 is threaded into the first screw hole 18. One end of the screw 19 is rotatably connected to the clamping block 13, and the other end is fixedly connected to a handle 20. The handle 20 drives the screw 19 to rotate, which can move the connecting plate 17 away from or away from the clamping block 14. The clamping plate 14 moves closer to or further away from the clamping block 13 via the limiting rod 16, allowing the clamping plate 14 to clamp or release the dental floss 28. The clamping block 13 has an arc-shaped limiting groove 21 on the side near the clamping plate 14 for placing the dental floss 28. When the dental floss 28 is clamped, it can limit the position of the dental floss 28, improving its stability and the accuracy of the test. The clamping plate 14 has an anti-slip rubber pad 22 on the side near the clamping block 13 to increase the friction on the dental floss 28 and prevent the dental floss from slipping.
[0028] Two wear-resistant heads 7 are fixedly connected to adjusting rods 23 on opposite sides. The support rod 6 has adjusting holes 24 that slide with the adjusting rods 23. The top of the support rod 6 has a second screw hole 25 that communicates with the adjusting holes 24. An adjusting bolt 26 is threaded into the second screw hole 25. When the adjusting bolt 26 is tightened, it can press the adjusting rod 23 into the adjusting hole 24, thereby fixing the wear-resistant head 7. When the adjusting bolt 26 is loosened, the gap between the two wear-resistant heads 7 can be adjusted, or the worn wear-resistant head 7 can be replaced, increasing its practicality.
[0029] Working principle:
[0030] like Figure 1-3 As shown, when using the dental floss abrasion testing equipment, the two ends of the dental floss 28 to be tested are placed in the limiting grooves 21 of the two clamping blocks 13 respectively. Then, by rotating the handle 20, the screw 19 is rotated, which drives the connecting plate 17 to move away from the clamping block 13. In turn, the connecting plate 17 drives the clamping plate 14 to move closer to the clamping block 13 through the limiting rod 16, so that the clamping plate 14 can clamp the dental floss 28.
[0031] After both ends of the dental floss 28 are fixed, the controller starts the motor 8, which drives the turntable 9 to rotate. While the turntable 9 is rotating, the push rod 10 pushes the slide rod 4 to reciprocate within the slide hole 3. The slide rod 4 drives the clamping mechanism through the vertical plate 5, which in turn drives the dental floss 28 to reciprocate, replacing manual operation of the dental floss 28 and preventing hand fatigue. The reciprocating motion of the dental floss 28 allows it to pass through the gap between the two abrasion-resistant heads 7 multiple times, causing the dental floss to rub against the surface of the abrasion-resistant heads 7 multiple times, thus performing a wear resistance test on the dental floss. After the output end of the motor 8 rotates a certain number of times, the controller stops the motor 8. If no breakage occurs in the dental floss, the dental floss is considered to have passed the test. This testing method can greatly reduce the variability of operation and improve the accuracy of the test results.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
