Description

Technical Field

[0001] This utility model relates to the field of dental floss production and processing technology, specifically to a dental floss transfer device for achieving smooth transfer of dental floss between the production and packaging stages. Background Technology

[0002] In dental floss production, the injection molding process is crucial. It precisely integrates the fiber filaments and the handle into a single piece, resulting in a complete and practical floss structure. After injection molding, the dental floss undergoes subsequent processing such as high-temperature sterilization and coloring to meet hygiene standards and market demands.

[0003] To make production more compact and efficient, the finished dental floss is strung on a fixture that connects to the injection molding machine, simplifying the process and improving efficiency. However, existing dental floss carrier designs have limitations, focusing primarily on the production process and lacking adaptability to automated packaging. For automated packaging, a transfer device is needed to guide the dental floss from the production fixture to the packaging line. Currently, however, the packaging transfer device and the production fixture lack effective docking, preventing seamless integration. In actual production, manual transfer of the dental floss is often required. This is not only labor-intensive and inefficient but also prone to damage or inaccurate transfer due to human error, affecting packaging quality and schedule. Summary of the Invention

[0004] To overcome the above-mentioned defects, this utility model provides a dental floss transfer device that can achieve a smooth connection between the dental floss production and packaging stages, thereby reducing material turnover and lowering production costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is to provide a dental floss transfer device, including a transfer tray and a transfer component. The transfer tray includes a support plate and a plurality of partitions evenly spaced on the support plate, and a floss insertion assembly is provided between adjacent partitions.

[0006] The insert assembly is movably connected to the support plate and includes multiple insert rods. Each insert rod includes a cylindrical body for threading dental floss and a conical body integrally connected to the end of the cylindrical body. The conical body has a mating slope, which is inclined outward along the central axis of the insert rod and toward the axial section.

[0007] The transfer component is in the shape of a cylindrical rod, with a guide portion at one end that can overlap the conical body. The guide portion includes an overlapping plane that matches the docking slope and a guide slope that is opposite to the overlapping plane.

[0008] As a further improvement of this utility model, dental floss is inserted through the annular portion of the floss onto the cylindrical body. The cylindrical body is provided with a positioning plane, which is connected to the mating inclined surface and formed on the axial section of the cylindrical body.

[0009] Meanwhile, an arc-shaped recess is provided in the middle of the positioning plane.

[0010] As a further improvement of this utility model, the guide slope is inclined outward along the central axis of the transfer member and toward the axial section side, and the radial section formed by the guide slope and the overlapping plane at the end of the transfer member is a circular arc trapezoid.

[0011] As a further improvement of this utility model, the angle between the positioning plane and the mating inclined plane is in the range of 160° to 180°.

[0012] As a further improvement of this utility model, limiting cuts are respectively provided at both ends of the transfer component. The limiting cuts have a bottom surface formed on the axial section of the transfer component and oblique cut surfaces provided on both sides of the bottom surface in the axial direction.

[0013] The oblique cut surface at one end of the guide portion facing the transfer component is connected to the overlapping plane.

[0014] As a further improvement of this utility model, the angle between the oblique surface and the bottom surface ranges from 145° to 170°.

[0015] As a further improvement of this utility model, the insert assembly further includes:

[0016] A carrier block, wherein multiple positioning slots are spaced apart along its length;

[0017] An auxiliary rod is provided on the carrier block corresponding to the insert rod, so that the dental floss is strung on the insert rod with a uniform orientation;

[0018] The insert rod also includes a positioning block adapted to the positioning groove, and a support block disposed between the positioning block and the cylindrical body.

[0019] As a further improvement of this utility model, the support plate is provided with positioning pins between two adjacent partitions, and the carrier block of the insert assembly is provided with pin holes that are adapted to the positioning pins.

[0020] As a further improvement of this utility model, the support plate is provided with multiple weight-reducing grooves.

[0021] As a further improvement of this utility model, the partition has an L-shaped structure, and its horizontal section is detachably connected to the support plate.

[0022] The beneficial effects of this utility model are: by setting up the insert component and the transfer component, the dental floss production and packaging processes can be directly and efficiently connected; at the same time, after the dental floss on the transfer tray is fed, it can be directly returned to the production process for reuse, reducing material turnover, saving production processes and reducing costs.

[0030] The preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] See Figures 1 to 5 This utility model provides a dental floss transfer fixture, which mainly consists of two parts: a transfer tray 1 and a transfer component 2. The transfer tray 1 is used to realize the transfer of dental floss between different processes in the production process; the transfer component 2 serves to connect the production process and the packaging process. It can dock with the transfer tray 1 to transfer the dental floss on the transfer tray 1 to the fully automatic dental floss packaging machine, thereby completing the packaging operation of the dental floss.

[0032] It should be noted that the function of the transfer component is consistent with that of the "material-carrying chopsticks" disclosed in the Chinese invention patent application CN114313416B, entitled "Fully Automatic Dental Floss Packaging Machine." Both are used to string dental floss and ensure its smooth flow between various mechanisms of the fully automatic packaging machine. Specifically, the Chinese invention patent discloses: a dental floss feeding mechanism for picking up a turnover box and transferring the material-carrying chopsticks containing a number of dental flosses from the turnover box to the dental floss conveyor device; and a dental floss counting and supplementary mechanism for picking up the material-carrying chopsticks from the dental floss conveyor device and quantitatively transferring the dental floss to the bagging mechanism. The rotary packaging device is equipped with a bag loading station, a filling station, and a sealing station. The rotary packaging device picks up the packaging bags from the bag feeding mechanism at the bag loading station and moves them to the filling station. The bag opening forming mechanism is used to open and form the bag opening of the moved packaging bag, and the filling mechanism neatly stacks the dental floss into the packaging bag. The rotary packaging device can drive the filled packaging bag to the sealing station for sealing.

[0033] The difference lies in the fact that the transfer component in this embodiment can directly connect with the transfer tray, thus eliminating the need for an additional turnover box and achieving a direct and efficient connection between the dental floss packaging and production processes. Furthermore, after the dental floss on the transfer tray has been unloaded, the tray can be directly returned to the production process for reuse as a material-carrying fixture, effectively improving the utilization rate of production resources, reducing unnecessary material turnover, thereby saving on production flow and lowering production costs.

[0034] Specifically, the transfer tray 1 includes a support plate 11 and multiple partitions 12 evenly spaced on the support plate 11. The support plate is used to position the insert assembly to ensure its stability during transfer. The partitions 12 divide the space into independent, non-interfering spaces, ensuring the orderly placement of the dental floss F. The partitions 12 are L-shaped, with their horizontal sections detachably connected to the support plate 11. This detachable connection provides great flexibility, allowing for easy adjustment of the spacing between the partitions 12 to meet the production requirements of different specifications or quantities of dental floss. The support plate 11 has multiple weight-reducing grooves 112, which reduce the overall weight of the fixture while maintaining the strength of the support plate 11, facilitating operation and handling. The support plate 11 is provided with positioning pins 111 between two adjacent partitions 12. The carrier block 132 of the insert assembly 13 is provided with pin holes 1322 that are adapted to the positioning pins 111. Through the cooperation of the positioning pins 111 and the pin holes 1322, the insert assembly 13 is accurately positioned and stably installed on the support plate 11, while ensuring that the insert assembly can quickly detach from the support plate under the action of external force.

[0035] The insert assembly 13 is movably connected to the support plate 11 and includes a carrier block 132 and multiple insert rods 131 and auxiliary rods 133 arranged on the carrier block 132. The carrier block 132 has multiple positioning slots 1321 spaced apart along its length. The auxiliary rods 133 are correspondingly positioned on the carrier block 132 to the insert rods 131. The dental wire F passes through the annular portion on the carrier block 132 and is inserted onto the cylindrical body 1311 of the insert rod 131. The auxiliary rods 133 are located beside the insert rods, allowing the dental wires to be strung on the insert rods 131 with a uniform orientation. Figure 1 As shown, the floss handle is positioned precisely between two adjacent auxiliary rods, ensuring the neatness of the floss string. The insert rod 131 includes a cylindrical body 1311, a conical body 1312 integrally connected to the end of the cylindrical body 1311, a positioning insert 1313 adapted to the positioning groove 1321, and a support block 1314 disposed between the positioning insert 1313 and the cylindrical body 1311. The cylindrical body 1311 has a positioning plane 13111, which is connected to the mating inclined surface 13121 of the conical body 1312 and formed on the axial section of the cylindrical body 1311. An arc-shaped recess is provided in the middle of the positioning plane 13111, so that the floss fiber F0 is just suspended above the positioning plane. On the one hand, it effectively limits the movement of dental floss and prevents it from shaking during the transfer process, ensuring the stability of the floss position and avoiding problems such as floss misalignment and tangling caused by shaking, thus ensuring the smooth progress of the transfer process. On the other hand, when the floss is being connected, the small contact area between the floss and the insert rod during the movement reduces the friction between the two, ensuring the transfer of the floss.

[0036] The included angle β between the positioning plane 13111 and the docking inclined plane 13121 is in the range of 160° to 180°, preferably 170°. This angle design ensures the structural strength of the insert rod 131 and facilitates docking with the transfer piece 2.

[0037] Furthermore, the transfer component 2 is a cylindrical long rod, with a guide portion 21 at one end that can overlap the conical body 1312. The guide portion 21 includes an overlapping plane 211 adapted to the mating inclined surface 13121, and a guide inclined surface 212 disposed opposite to the overlapping plane 211. The guide inclined surface 212 is inclined outward along the central axis of the transfer component 2 and towards the axial section side. The radial section formed by the guide inclined surface 212 and the overlapping plane 211 at the end of the transfer component 2 is a circular arc trapezoid, so as to facilitate the smooth and even transition of the dental wire from the insert rod 131 to the transfer component 2, while ensuring that the transition process does not cause jamming.

[0038] Limiting cuts 213 are also provided at both ends of the transfer piece 2. The limiting cuts 213 have a bottom surface 2131 formed on the axial section of the transfer piece 2 and oblique cut surfaces 2132 on both sides of the bottom surface 2131. The oblique cut surface 2132 facing the guide part 21 of the transfer piece 2 is connected to the overlapping plane 211. The angle α between the oblique cut surface 2132 and the bottom surface 2131 is in the range of 145° to 170°, preferably 156°. The limiting cuts 213 can further limit the docking of the transfer piece 2 and the insert rod 131 to ensure the accuracy of the docking. At the same time, the setting of the limiting cuts is used to realize the stable conveying of the transfer piece on the dental floss conveyor device of the fully automatic packaging machine.

[0039] Understandably, to ensure the smooth transfer of dental floss from the insert rod to the transfer unit, existing mature methods can be used before the docking operation begins. For example, a high-precision, stable robotic arm can be used to smoothly and completely lift the insert assembly from the support plate, and then adjust it to a horizontal position, as shown in Figure 2. After the dental floss on the insert assembly is transferred to the transfer unit, the robotic arm resets the insert assembly to a vertical position and then places it back on the support plate, thus achieving the cyclical use of the transfer tray.

[0040] In summary, the dental floss transfer device provided by this utility model has a simple structure and is easy to operate. Through the insertion component and the transfer mechanism, it achieves direct and efficient connection between the dental floss packaging and production stages. Furthermore, after the dental floss on the transfer tray has been unloaded, the transfer tray can be directly returned to the production stage as a reusable material carrier, effectively improving the utilization rate of production resources, reducing unnecessary material turnover, thereby saving on production flow processes and reducing production costs.
