Description

Technical Field

[0001] The present invention relates to the technical field of high-frequency welding, and more specifically, to a high-frequency welding machine. Background Art

[0002] High frequency welding machine is a high frequency welding equipment, mainly used for welding plastic materials. High frequency welding machine uses high frequency electromagnetic field to repeatedly twist and rub polar molecules inside plastic (such as polyvinyl chloride and other materials), thereby generating heat. This heat is gathered at the welding part of the plastic. When the temperature reaches the melting point of the plastic, the two plastic parts are fused together under the action of pressure. At present, in the field of medical equipment, the connection between the infusion tube and the infusion bag is welded by high frequency welding machine.

[0003] According to the search, the patent number CN218804071U discloses a high-frequency welding machine, including a heat sealing plate, a booster cylinder for driving the heat sealing plate to press vertically downward, and a horizontal workbench, the workbench is provided with a guide rail, a base frame is slidably provided on the guide rail, and the base frame is provided with a fixing part for fixing the grey cloth and a calibration part for facilitating the adjustment of the position of the print and the grey cloth; at the same time, a limit block is provided on the guide rail for limiting the end point of the sliding of the base frame, when the base frame abuts against the limit block, the print is located directly below the heat pressing plate, thereby improving the accuracy of the hot pressing, and converting the alignment of the heat sealing plate and the print into the alignment of the grey cloth, the print and the base frame, thereby reducing the probability of the line of sight being blocked by the heat sealing plate during alignment.

[0004] With regard to the above-mentioned related technologies, when welding the infusion tube and the infusion bag, it is first necessary to put the infusion tube on the cylindrical mold to prevent the infusion tube from deforming during welding, and then put the bag mouth of the infusion bag on the outside of the infusion tube, and then turn on the high-frequency welding machine to weld the infusion tube and the infusion bag. However, in the actual operation process, when using the welding machine to weld the infusion tube and the infusion bag, there is a probability that incomplete welding caused by material factors, equipment factors or operation factors will be found. Incomplete welding will cause leakage problems in the infusion bag, and it is difficult for the staff to distinguish and judge, resulting in difficulty in ensuring the machine's yield rate. Unified transportation and use will seriously affect the subsequent filling of the liquid medicine. For this reason, a high-frequency welding machine is proposed. Summary of the invention

The staff will remove the infusion bag that does not meet the requirements. When the sliding table 260 and the L-shaped table 220 move, the rotating rod 252 will be pulled by the pull rope to rotate, and at this time the torsion spring 253 will be tightened, and the ratchet block 243 will move inside the ratchet groove 241,When the L-shaped platform 220 stops moving, the ratchet block 243 cooperates with the ratchet groove 241 to lock the L-shaped platform 220 that has stopped moving. After all the infusion tubes and infusion bags are welded, the staff removes all qualified finished products, and then pulls the ratchet block 243 out of the ratchet groove 241. The torsion spring 253 will drive the rotating rod 252 and the winding roller 254 to rotate and wind up the pull rope, thereby pulling the L-shaped platform 220 and the sliding platform 260 to reset, and the sliding platform 260 is buffered by the buffer pad 255. The staff will then place it again, thereby repeating the welding of the infusion tube and the infusion bag.

[0044] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
