Automatic blood taking needle packaging equipment

Abstract

The invention relates to the technical field of blood taking needle packaging equipment, in particular to automatic blood taking needle packaging equipment. The automatic blood taking needle packagingequipment comprises a rack and also comprises a material taking and distance changing device, a winding device, a material storing and transferring device, a packaging bag processing production line,a packaging bag sealing and transferring device, a hot welding device and an output device which are arranged on the rack, wherein the packaging bag processing production line comprises a packaging bag taking and aligning device, a packaging bag pre-opening device and a packaging bag opening device. According to the automatic blood taking needle packaging equipment, blood taking needles can be efficiently and accurately taken, wound and fed into a packaging bag, and then the packaging bag is smoothly moved to the hot welding device to be subjected to hot welding sealing, so that the automation degree of blood taking needle packaging is greatly improved.

Description

technical field [0001] The invention relates to the technical field of packaging equipment for blood collection needles, in particular to automatic packaging equipment for blood collection needles. Background technique [0002] The blood collection needle is an instrument used to collect blood samples in the medical examination process. It consists of a needle and a needle bar. The needle is set at the head of the needle bar, and a sheath is slidably connected to the needle bar. A return spring is arranged between and the initial position of the sheath is located at the head of the needle and the needle bar. After the blood collection needles are produced, they need to be individually packaged one by one. When packaging, the blood collection needles need to be grabbed, wound into a roll, the rolled blood collection needles are packed into a separate packaging bag, and then the packaging bag is sealed. [0003] The existing blood collection needle packaging equipment has a l...

AI Technical Summary

Problems solved by technology

[0003] The existing blood collection needle packaging equipment has a low degree of automation, and at least includes the following deficiencies in use: (1) There is basically no special blood collection needle retrieving device, and some enterprises use the method of directly grabbing the blood collection needle with a manipulator, which takes up a large space for the equipment and is difficult to operate. Low efficiency, not only easy to damage the blood collection needle during the grabbing process, but also irregular blood collection needle, which is not conducive to the subsequent winding operation; (2) The blood collection needle winding device is semi-automatic, manual feeding, manual winding, low work efficiency, during the winding process It is easy to cause pollution in the medium, and it is easy to cause damage to the hose, and the winding quality is unstable

The degree of automation of some automatic winding devices is not high, the operation continuity is poor, and the coiled blood collection needle hose is easily damaged during the process of removing it from the equipment; (3) when transferring the wound blood collection needle to the packaging bag During the transfer process, the degree of automation of the transfer equipment is not high. During the transfer process, the blood collection needle tube tends to rebound and loosen, which leads to the failure of the blood collection needle coil to be smoothly packed into the packaging bag. The stability of the blood collection needle coil is poor. In addition, there is a risk of falling; (4) There is no special packaging bag alignment mechanism, which causes the packaging bag to be shifted after it is taken out of the storage bin for the packaging bag, and there is inconvenience in the subsequent opening process of the bag. After the bag is taken down, it is directly moved to the bag opening device for bag opening operation. During the moving process, the packaging bag is easy to fall off, and the packaging bag is directly opened on the opening device, which is prone to deformation of the opening end of the packaging bag, and the inside of the packaging bag is not damaged. If the blood collection needle is opened properly, the bagging of the blood collection needle fails; (5) The blood collection needle wound into a roll is transferred to the packaging bag by the transfer device, and then the transfer device needs to be pulled out from the packaging bag. At the mouth, it affects the subsequent transfer to the sealing device and the sealing operation. The packaging bag contains some air, and the existing transfer equipment cannot smoothly press out the air in the packaging bag. After the wind sealing is completed, the packaging bag is squeezed and easy to explode; ( 6) The packaging bag heat welding device cannot flexibly adjust the relative positions of the upper pressing mechanism and the lower pressing mechanism according to the actual needs such as the thickness of the packaging bag, and the local structures in the upper pressing mechanism and the lower pressing mechanism cannot be repaired and replaced after damage. convenient
