Description

Technical Field

[0001] The invention belongs to the technical field of slitting devices, and in particular relates to a medical blister packaging forming and slitting device. Background Art

[0002] The medical blister packaging forming and slitting device is a device specially used in the medical industry. Its main function is to form the heated and softened thermoplastic plastic sheet into blister packaging of various shapes through a mold, and accurately cut the formed packaging through the slitting device to meet the packaging needs of different medical supplies. However, the existing slitting device cannot quickly replace the corresponding cutting tool to suit the cutting of blister packaging according to different usage requirements. For example, the use of a straight cutter (flat knife) is suitable for harder plastic materials and can produce a flat and smooth incision. The edge of the material cut by a circular cutter will not have obvious burrs; a serrated cutter effectively cuts soft plastic materials, and a V-shaped cutter has a sharp blade and is suitable for cutting softer plastic materials.

[0003] At present, Chinese patent CN201710531976.5 discloses a dialysis paper slitting device, including a frame, a heating plate, a slitting knife and a bottom plate. Support frames are installed on both sides of the top of the frame, a driving shaft is installed at the output end of the first motor, and driven shafts are installed on the support frames on both sides of the driving shaft. A heating plate is installed at the bottom end of the telescopic rod, and an irregular concave ring is installed on the transmission shaft inside the second shell, and a slitting knife is installed at the bottom end of the irregular concave ring. The present invention is provided with a first motor, a driving shaft, a driven shaft and a belt. The dialysis paper is sleeved on the upper driven shaft and passes between the driving shaft and the driven shaft, passes between the bottom plate and another driving shaft and the driven shaft, and is wound around the upper driven shaft, so that the dialysis paper automatically moves forward and is collected, thereby integrating the operation and collection and sorting of the device, enhancing the mobility of the device and facilitating the use of the staff.

[0004] Chinese Patent CN202110967412.2 A medical dialysis paper slitting device comprises a fixed plate, a protective mechanism is installed on the fixed plate for installing the overall structure on the wall, a fixing mechanism for fixing the dialysis paper tube is installed on the fixed plate, a pressing mechanism for guiding the dialysis paper is provided on the fixed plate, a clamping mechanism located on the bottom side of the pressing mechanism is provided on the fixed plate, a driving mechanism is installed on the fixed plate, a slitting mechanism is installed on the fixed plate, the driving mechanism controls the slitting mechanism to cut the dialysis paper, and a buffer mechanism for buffering the fixing mechanism is provided on the fixed plate; the clamping mechanism on the fixed plate cooperates with the pressing mechanism to clamp the dialysis paper, and when the required dialysis paper is cut off, the pressing mechanism and the clamping mechanism can also clamp the beginning of the dialysis paper on the fixed mechanism, push the pressing mechanism to leak the dialysis paper, and then pull out the dialysis paper, which is convenient for taking out the dialysis paper next time.

[0005] The current patents are mainly aimed at the clamping, positioning and cutting of the slitting mechanism to avoid contamination, but there is no innovation on how to achieve quick tool change to be suitable for the cutting of a variety of injection molding packaging materials, which greatly increases the cost when replacing the tool.

[0036] See also Figure 1-3The present invention provides a technical solution: a medical blister packaging forming and slitting device, comprising a workbench 1, a support frame 2 is arranged on the workbench 1, a conveying mechanism 3 and a limiting mechanism 4 are arranged on the support frame 2, a lifting cylinder 5 is arranged on the top of the support frame 2, the lifting cylinder 5 passes through the support frame 2 and is connected to a quick-change tool slitting mechanism 6, and the quick-change tool slitting mechanism 6 is located on the top of a positioning platform 7.

[0037] The positioning platform 7 is located at the front end of the conveying mechanism 3 .

[0038] The limiting mechanism 4 includes a telescopic cylinder 41, a connecting plate 42 and a limiting wheel 43, wherein the connecting plate 42 is connected to the telescopic cylinder 41, and the limiting wheel 43 is rotatably connected to the connecting plate 42. The limiting transmission of both ends of the medical blister packaging is realized to ensure accurate cutting by the tool.

[0039] The quick-change tool slitting mechanism 6 includes a protective shell 61 , a connecting piece 62 , a rotating cylinder 63 and a plurality of cutting tools 64 . The plurality of cutting tools 64 are detachably connected to the rotating cylinder 63 , and the rotating cylinder 63 is connected to the protective shell 61 via the connecting piece 62 .

[0040] The bottom of the protective shell 61 is provided with a slot 8 , and the cutter 64 at the bottom extends out of the slot 8 .

[0041] The tool 64 is provided with a buffer 9 so that the tool can achieve buffering during the slitting process.

[0042] The protective shell 61 is provided with a first limiting groove 10 , the rotating cylinder 63 is provided with a second limiting groove 11 , one end of the connecting member 62 is connected to the first limiting groove 10 , and the other end is connected to the second limiting groove 11 .
