Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of labeling equipment, and in particular to an automatic labeling machine for a pre-filled tubing syringe. Background Technology
[0002] Pre-filled syringes are widely used in medical, health, and animal health fields. A pre-filled syringe is a syringe pre-injected with a certain amount of medication, typically consisting of a medication container and a syringe head. It reduces the steps required for users to dispensing and inject medication by pre-filling the syringe. The medication container is usually non-recyclable or non-reusable and contains a certain amount of air to act as the pressure source for ejecting the medication during injection. Labeling the syringes is necessary to effectively identify the medication information. However, when labeling small quantities, purchasing specialized syringe labeling equipment not only increases production costs but also occupies factory space. Existing technology publication number CN217023243U discloses a labeling device for storing syringes, including a support frame configured as a horizontal C-shaped plate; and a push block located in the middle of the support frame and horizontally slidably connected to it. The beneficial effects are: This invention incorporates the extensibility of an elastic rope, causing the horizontal elastic rope to deform upon contact with the outer wall of the syringe and wrap around it, thus pressing the label flat against the syringe wall for complete adhesion. The rotating block's rotation is restricted by the rotating block's structure and the limiting rod, causing the rotating block to open to both sides under the action of a rotating spring when the push block moves to the label position. This facilitates the transfer of the label to the front center of the clamping plate, and the label moves through the clamping action of the rotating block and the clamping plate. However, the clamping force is difficult to control, which can easily lead to the label not adhering properly or damage to the pre-filling needle. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a pre-filled tubing syringe automatic labeling machine that allows for easy adjustment of the labeling position, can compact the label, and ensure the label's firm adhesion.
