Description

Technical Field

[0001] The utility model relates to a welding device for a first aid pack tie buckle. Background Art

[0002] First aid bandages are gauze bandages used to bandage wounds or affected areas. They are common medical supplies and come in many different types and bandaging methods. There are two traditional types of bandages. One is to fix a gauze bandage at the end of the bandage and bandage and fix it by tying the gauze bandage. The disadvantage of this type of bandage is that it requires both hands or the assistance of others to bandage and cannot be done with one hand. The other is to make the bandage self-adhesive by applying glue and adding wrinkles. This type of bandage can be fixed with one hand, but it has the disadvantage of poor air permeability and is easy to cause itching and stuffiness on the skin.

[0003] There is a new type of bandage now. There is a fixed shaft at the innermost end of the bandage, and a C-shaped buckle at the tail end of the bandage. After bandaging, the fixed shaft at the inner end of the bandage is directly inserted into the C-shaped buckle to complete the fixation. This bandage can ensure the breathability of the material and achieve one-handed bandaging. At present, the fixing method of this C-shaped buckle and the bandage is mostly to directly adhere to the bandage body with glue, usually manually apply glue, and then apply a certain pressure to fix the buckle. This method has the following four disadvantages:

[0004] (1) The amount of glue applied is difficult to control. Too little glue will result in insufficient bonding strength, while too much glue will cause glue overflow, affecting the appearance of the product.

[0005] (2) Manual pressure cannot guarantee the stability and uniformity of pressure, which may easily lead to the problem of insufficient buckle bonding strength.

[0006] (3) Glue is affected by the environment to a certain extent. When the temperature is too high, the viscosity of the glue will decrease or become ineffective.

[0007] (4) The production efficiency is low, the process is time-consuming and labor-intensive, and the product quality stability is low. Utility Model Content

[0008] In order to overcome the above defects, the technical problem to be solved by the utility model is to provide a welding device for a first aid bag tie buckle.

[0009] In order to achieve the above-mentioned purpose, the welding device of the first aid kit tie buckle of the utility model comprises an operating table; the operating table is composed of supporting legs and a tabletop arranged on the supporting legs;

[0010] A vibrator is arranged below the table; a working hole is arranged on the table corresponding to the vibrator; the working end of the vibrator is located in the working hole, and the working surface of the working end is flush with the upper surface of the table;

[0011] An inverted L-shaped cylinder support frame is arranged on the table top;

[0012] A cylinder is arranged on the cylinder support frame corresponding to the vibrator;

[0013] The lower end of the cylinder rod of the cylinder passes downward through the support frame and is located above the table top; a rectangular welding head is arranged at the lower end of the cylinder rod;

[0014] A positioning device is arranged on one side of the welding head.

[0015] Furthermore, the positioning device includes a fixing portion and a U-shaped spring sheet; one side arm of the U-shaped spring sheet is connected to the fixing portion.

[0016] The utility model adopts cylinder drive, and completes the welding of C-shaped buckle and bandage through ultrasonic high-frequency vibration and external pressure. This welding method applies constant pressure to the material, which is controllable and adjustable, and has the advantages of firm welding, uniform force, high efficiency and convenience, and is not affected by ambient temperature. At the same time, the positioning device can better position the C-shaped buckle to ensure the consistency and accuracy of the buckle position. BRIEF DESCRIPTION OF THE DRAWINGS
