Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of dental floss stick production, and more particularly to a method for detecting the breaking strength of a dental floss stick. Background Art
[0002] Dental floss is a product used in conjunction with a toothbrush in daily oral care. It easily reaches narrow spaces between teeth that are difficult to reach with brushing, rinsing, and flossing. It effectively removes food debris, plaque, and soft tartar between teeth, thereby reducing the discomfort of foreign matter stuck between teeth and improving oral hygiene. Medical research shows that dental floss is more effective in preventing dental diseases than a toothbrush.
[0003] Dental floss sticks have become increasingly familiar to consumers in recent years. Dental floss sticks are made by attaching dental floss to a stick, allowing users to hold the stick and floss between teeth. Therefore, the tightness of the floss directly affects its ability to clean between teeth. Currently, dental floss sticks are tested for tensile strength before leaving the factory. This involves testing the tensile strength of each stick individually after it's formed. This process is inefficient, impacting the overall production efficiency of dental floss sticks. Summary of the Invention
[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a method for detecting the breaking strength of a dental floss stick.
[0005] To achieve the above object, the present invention has the following innovative features: specifically comprising the following steps:
[0006] S1. Injection-molded dental floss sticks: The dental floss sticks formed on the injection mold are taken out as a whole, and the dental floss sticks on each injection mold are divided into a group, and adjacent dental floss sticks in each group are in a state of being connected to each other;
[0007] S2. Testing the strength of the dental floss: Performing a tensile test on the dental floss sticks in each group. Dental floss sticks that meet the tensile strength requirements are kept connected, while dental floss sticks that fail the tensile test are dropped from each group.
[0008] S3. Cutting: Cut each set of dental floss sticks with qualified dental floss strength.
[0009] Furthermore, in step S2, all dental floss sticks in each group are tested simultaneously using a three-point testing method.
[0010] Furthermore, the specific process of the above three-point detection method is as follows: use several three-point clamps to clamp the two ends and the center position of the dental floss of each dental floss stick respectively, then fix the dental floss stick, and use external force to pull the three-point clamps to complete the tension test of the dental floss stick.
[0011] Furthermore, the above-mentioned three-point clamp includes three connecting rods connected by hinged ends and three fixing rings. The top of the fixing ring is connected to the connecting rod, the bottom of the fixing ring is provided with a wire clamping groove, the inside of the fixing ring is provided with a hook groove extending toward the wire clamping groove, the top of the three connecting rods is provided with a pull ring, and fixing columns are connected in series between several pull rings.
[0012] Furthermore, a plurality of positioning threaded holes are evenly distributed on the fixing column, and a fixing bolt is provided on the pull ring. The fixing bolt is aligned with the positioning threaded holes so that the fixing seat is fixed inside the pull ring.
[0013] Technical effects and advantages of the present invention:
[0014] 1. The present invention provides a method for testing the breaking strength of dental floss sticks. Before cutting the dental floss sticks one by one, a tensile strength test is performed on each group of dental floss sticks. This test can identify dental floss sticks with unqualified tensile strength in advance, and finally cut the dental floss sticks with qualified tensile strength, thereby reducing the cutting of dental floss sticks with unqualified tensile strength and improving the production efficiency of dental floss sticks.
[0015] 2. The present invention provides a method for testing the breaking strength of dental floss sticks. The three-point testing method can simultaneously test both ends and the center of the dental floss stick, providing a more comprehensive tensile testing position. Furthermore, during the testing process, if the tensile strength of the dental floss stick fails to meet the requirements, the ends of the dental floss stick will also break under the force, thereby automatically removing the dental floss sticks with unqualified tensile strength from each group of dental floss sticks. This reduces the need for manual removal of unqualified dental floss sticks and further ensures the production efficiency of dental floss sticks.
[0016] 3. The present invention provides a method for testing the breaking strength of a dental floss stick. When the fixing column is connected in series to the interior of the pull ring, the positioning threaded hole can position the fixing column in series inside the pull ring, ensuring that the pull ring is evenly distributed on the fixing seat. The fixing bolts and the positioning threaded holes are fixed so that the pull ring is fixed inside the pull ring, ensuring that the fixing seat can remain stable when the pull ring is pulled, thereby ensuring the stability of the tension test.

[0018] Figure 2 This is a structural diagram of the fixing column inside the pull ring of the present invention. DETAILED DESCRIPTION
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] like Figures 1 to 2 A specific embodiment of the present invention includes the following steps:
[0021] S1. Injection-molded dental floss sticks: The dental floss sticks formed on the injection mold are taken out as a whole, and the dental floss sticks on each injection mold are divided into a group, and adjacent dental floss sticks in each group are in a state of being connected to each other;
[0022] S2. Testing the strength of the dental floss: Performing a tensile test on the dental floss sticks in each group. Dental floss sticks that meet the tensile strength requirements are kept connected, while dental floss sticks that fail the tensile test are dropped from each group.
[0023] S3. Cutting: Cut each set of dental floss sticks with qualified dental floss strength.
[0024] In the present invention, before the dental floss sticks are cut one by one, the tensile force test is performed on the dental floss sticks in each group first. This test can identify the dental floss sticks with unqualified tensile force in advance, and finally the dental floss sticks with qualified tensile force are cut, thereby reducing the cutting of dental floss sticks with unqualified tensile force, thereby improving the production efficiency of dental floss sticks.
[0025] In the present invention, as a preferred solution, in step S2, all dental floss sticks in each group are tested simultaneously using a three-point testing method.
[0026] In the present invention, as a preferred embodiment, the three-point detection method is specifically designed as follows: a plurality of three-point clamps are used to clamp the two ends and the center of the dental floss of each dental floss stick respectively, and then the dental floss stick is fixed, and an external force is applied to pull the three-point clamps to complete the tensile force test of the dental floss stick.
[0027] In the present invention, the three-point detection method can simultaneously detect both ends and the center position of the dental floss stick, and the tension detection position is more comprehensive. Moreover, during the detection process, if the tension of the dental floss stick is unqualified, the end of the dental floss stick will also break under the force, so that the dental floss stick with unqualified tension will automatically be separated from each group of dental floss sticks, reducing the process of manually removing unqualified dental floss sticks and further ensuring the production efficiency of dental floss sticks.
[0028] In the present invention, as a preferred embodiment, the above-mentioned three-point clamp includes three connecting rods 1 and three fixed rings 2 connected by hinges at the three ends. The top of the fixed ring 2 is connected to the connecting rod 1, and the bottom of the fixed ring 2 is provided with a wire clamping groove 21. The inside of the fixed ring 2 is provided with a hook groove 22 extending toward the wire clamping groove 21. The tops of the three connecting rods 1 are provided with pull rings 3, and fixed columns 4 are connected in series between several pull rings 3.
[0029] In the present invention, the working principle of the three-point clamp is as follows: the wire clamping grooves 21 on the three fixing rings 2 are respectively clamped into the two ends and the middle position of the dental floss pick, and then the three positions are sequentially clamped into the inside of the hook groove 22, so that the hook groove 22 hooks the dental floss, and finally the external force pulls the fixing column 4, and the fixing column 4 pulls the pull ring 3 at the same time, so as to realize the tension test of all dental floss picks in each group.
[0030] In the present invention, as a preferred solution, a plurality of positioning threaded holes 41 are evenly distributed on the fixing column 4, and a fixing bolt 31 is provided on the pull ring 3. The fixing bolt 31 is aligned with the positioning threaded holes 41 so that the fixing seat is fixed inside the pull ring 3.
[0031] In the present invention, when the fixing column 4 is connected in series into the interior of the pull ring 3, the positioning threaded hole 41 can position the position of the fixing column 4 in series inside the pull ring 3, ensuring that the pull ring 3 is evenly distributed on the fixing seat, and the fixing bolt 31 and the positioning threaded hole 41 are fixed so that the pull ring 3 is fixed inside the pull ring 3, ensuring that the fixing seat can remain stable when pulling the pull ring 3, thereby ensuring the stability of the tension detection.
