Technical Field
[0001] This utility model belongs to the technical field of small bag packaging machines, specifically relating to a measuring mechanism for a dental floss packaging machine. Background Technology
[0002] As people's living standards improve, the use of dental floss is becoming increasingly widespread, and the market demand for dental floss packaging is also constantly increasing. However, existing dental floss packaging measurement mechanisms have many problems. Dental floss has a non-standard shape, and traditional packaging measurement methods are difficult to accurately count and neatly arrange, resulting in inaccurate quantities and messy arrangements of dental floss inside the packaging, affecting product quality and user experience.
[0003] Currently, the metering mechanisms of some dental floss packaging machines are complex in structure, cumbersome to operate, have high maintenance costs, and are inefficient, failing to meet the needs of large-scale production. Furthermore, some metering mechanisms lack adaptability and flexibility when dealing with dental floss of different specifications and shapes. These problems limit the development of the dental floss packaging industry, urgently requiring an innovative metering mechanism to solve them. Utility Model Content
[0004] To address the problems mentioned in the background section, this invention provides a highly efficient and precise metering mechanism for dental floss packaging machines. This mechanism enables accurate metering and neat arrangement of dental floss for packaging, meeting the needs of multi-piece dental floss packaging while improving packaging efficiency and reducing production costs.
[0005] Structural composition: The metering mechanism is mainly composed of a base plate, guide groove, upper and lower cylinders of the feeding groove, left and right cylinders of the feeding claw, upper and lower cylinders of the feeding claw, clamping cylinder of the feeding claw, clamping cylinder of the pushing claw, pushing cylinder, feeding cylinder, unloading cylinder and other components.
[0006] Connection and Position Relationships: The guide channel is mounted on the base plate, and the feeding trough is installed on the upper and lower cylinders of the feeding trough, with the feeding trough located above the guide channel on one side. The left and right cylinders of the feeding claw control the horizontal movement of the feeding claw, and the upper and lower cylinders of the feeding claw control the vertical movement of the feeding claw. The feeding claw clamping cylinder is used to control the clamping or releasing of the feeding claw. The pushing claw clamping cylinder controls the clamping and releasing of the pushing claw, and the pushing cylinder drives the pushing claw to move horizontally. The feeding cylinder and the unloading cylinder are used to push the feeding thread into the unloading preparation position and open the unloading gate to allow the feeding thread to enter the bag maker, respectively.
[0007] During equipment operation, the dental floss is first neatly placed in the feeding trough. The feeding claw's left and right cylinders move to the right, and after reaching the designated position, the feeding claw's up and down cylinders move downwards, positioning the dental floss in the middle of the feeding claw. Then, the feeding claw clamping cylinder operates, clamping the dental floss, and the feeding trough moves downwards. The feeding claw moves to the left, pulling the dental floss into the guide groove. The pushing claw releases and moves to the rightmost end, then clamps again and moves to the left, ensuring the dental floss is always under leftward pressure. When the equipment gives the discharge signal, the feeding cylinder pushes the dental floss forward into the discharge preparation position, and then the discharge cylinder opens the discharge gate, allowing the dental floss to enter the bag maker downwards.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] Neat arrangement and accurate measurement: Through the coordinated operation of a series of cylinders, the dental floss inside the package can be arranged neatly, while achieving precise measurement and packaging of multiple pieces of dental floss, thus improving product quality.
[0010] Easy to operate and highly efficient: The metering mechanism has a reasonable structural design, is easy to operate, and the various actions are closely coordinated, which effectively improves packaging efficiency and reduces production costs.
[0011] Highly adaptable: It can adapt well to non-standard shapes of dental floss and can effectively measure and package dental floss of different specifications and shapes. Attached Figure Description
