Description

Technical Field

[0001] This utility model belongs to the field of membrane conveying, and specifically relates to a material dragging device for a thin film ring. Background Technology

[0002] Infusion sets are one of the most common medical devices in daily life. Medical infusion sets are usually assembled from tubing and various connectors. For pre-assembled medical infusion sets, they are usually rolled up to form an infusion set roll, and then a narrow membrane ring is used to clamp the outside of the infusion set roll. The membrane ring itself has a certain degree of elasticity, so the infusion set is not easy to loosen.

[0003] The film ring involves a conveying process before it is cut and formed. Current technology does not provide a film ring conveying device that is suitable for the purpose of film ring cutting, and further research and development are needed. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a film ring dragging device to adapt to the subsequent cutting process.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution.

[0006] A film ring dragging device includes a dragging telescopic drive and a telescopic platform connected to the movable end of the dragging telescopic drive. A dragging base plate is installed on the telescopic platform, and the film ring can be placed on the dragging base plate. A dragging bridge plate is also mounted on the dragging base plate. A dragging drive is provided on the dragging bridge plate. A dragging pressure plate is connected to the movable end of the dragging drive. The dragging pressure plate is driven by the dragging drive to press down on the film ring on the dragging base plate. The dragging telescopic drive drives the dragging pressure plate to move forward, thereby moving the film ring forward to complete the dragging action.

[0007] Furthermore, a lifting structure is connected to the movable end of the dragging drive component, and the lifting structure moves up and down simultaneously with the dragging pressure plate.

[0008] Furthermore, the lifting structure includes a lifting support plate that is laterally fixed to the movable end of the dragging drive component and lifting blocks located on both sides of the lifting support plate. The lifting blocks are L-shaped and have flat strips parallel to the conveying direction of the film ring. The flat strips can contact the edge of the film ring to lift it.

[0009] Furthermore, the flat strip has a chamfered bevel on the side facing the drag plate.

[0010] Furthermore, the flat strip also has side guards.

[0011] Furthermore, the material dragging base plate is provided with material limiting steps on both sides.

[0012] Furthermore, the top of the material limiting step is also equipped with an inward-facing upper baffle.

[0013] Compared with the prior art, the material feeding device of this invention can be used for feeding materials, and at the same time, it can work with the subsequent positioning components to press the two sides of the film ring together, which is convenient for the cutter to cut. The material feeding device is multi-purpose, with a compact overall structure, saving production space, and can efficiently complete the feeding and cutting pressing of the film ring.

[0014] The material dragging device of this utility model also includes a material lifting structure, which can effectively avoid the problem of the film ring end sagging when the material dragging device retreats. It can make the film ring end clamped by the subsequent positioning structure in a more relaxed state, thus avoiding the problem of overlapping wrinkles that may occur when the film ring end is clamped. The design is ingenious.

[0015] This material handling device can also be used for conveying thin materials similar to film rings, and its application is not limited. Attached Figure Description

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical solution of the present invention will be further described, but the present invention is not limited to these embodiments.

[0020] This specific embodiment is merely an explanation of the present invention, and the directions indicated are for the convenience of describing the technical content. It is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0021] like Figure 1 , 2As shown, this embodiment provides a film ring dragging device, including a dragging telescopic drive 1 and a telescopic platform 2 connected to the movable end of the dragging telescopic drive 1. The dragging telescopic drive 1 is mounted on a frame (not shown in the figure), and a dragging base plate 3 is mounted on the telescopic platform 2. The film ring can be placed on the dragging base plate 3. A dragging bridge plate 4 is also mounted on the dragging base plate 3, and a dragging drive 5 is provided on the dragging bridge plate 4. A dragging pressure plate 6 is connected to the movable end of the dragging drive 5. The dragging pressure plate 6 is driven by the dragging drive 5 to press down on the film ring on the dragging base plate 3. The dragging telescopic drive 1 drives the dragging pressure plate 6 to move forward, thereby moving the film ring forward to complete the dragging action.

[0022] A lifting structure 7 is also connected to the movable end of the dragging drive 5. The lifting structure 7 moves up and down simultaneously with the dragging pressure plate 6. The lifting structure 7 includes a lifting support plate 71 that is laterally fixed to the movable end of the dragging drive 5 and lifting blocks 72 located on both sides of the lifting support plate 71. The lifting blocks 72 are L-shaped and have flat strips 73 parallel to the film ring conveying direction. The flat strips 73 can contact the edge of the film ring to lift it. The side of the flat strip 73 facing the dragging base plate 3 has a beveled chamfer 74 so that the flat strip 73 can smoothly lift the film ring. The flat strips may also have side guards 75 to limit the lifting of the film ring laterally.

[0023] The material-carrying drive 5 drives the material-carrying pressure plate 6 to descend, pressing the film ring tightly onto the material-carrying base plate 53. Simultaneously, the flat strip 573 of the lifting structure 57 descends to the lower edge of the material-carrying base plate 53. Afterward, the material-carrying telescopic drive 51 drives the material-carrying base plate 53 to move forward, forming the film ring conveying process.

[0024] When the lifting structure 7 rises with the dragging platen 6, the lifting block 72 rises as well. When the dragging extension drive 1 drives the dragging platen 6 to move backward, the lifting block 72 moves backward simultaneously. The lifting block 72 can lift both ends of the film ring originally located at the front end of the dragging platen 6, making it easier for the subsequent positioning structure (not shown in the figure) to clamp the film ring for cutting. The lifting structure 7 can prevent the front end of the film ring from drooping after the dragging platen 6 moves backward, which would affect the subsequent clamping and cutting accuracy.

[0025] In this embodiment, the two sides of the material-carrying base plate 3 are provided with limiting steps 31 to limit the two sides of the film ring and prevent it from shifting. The top of the limiting steps 31 is also provided with an inward upper baffle 32 to limit the film ring in the vertical direction and prevent the film ring on it from arching upward when the material-carrying base plate 3 moves backward.

[0026] The working process of this device is as follows:

[0027] In the initial state, the material carrier plate 3 contains a film ring, which is an uncut strip. The material carrier plate 6 is pressed against the material carrier plate 3. Then, the material carrier drive 5 drives the material carrier plate 6 to rise, and simultaneously the flat strip block 73 rises. The material carrier extension drive 1 drives the material carrier plate 3 to retract to allow material to pass, while the flat strip block 73 retracts. The lifting block 72 gradually lifts both sides of the uncut film ring, bringing it to a relatively flat position. The positioning structure then clamps and positions the lifted edges of the film ring. Simultaneously, the material carrier drive 5 drives the material carrier plate 6 to descend, pressing the film ring firmly onto the material carrier plate 3. The flat strip block 73 of the lifting structure 7 descends synchronously to the lower edge of the material carrier plate 3. The two sides of the film ring to be cut are held and fixed by the material carrier plate 6 and the positioning structure, respectively. Then, the cutter cuts the film ring between the material carrier plate 6 and the positioning structure. After the film ring is cut, the dragging plate 6 rises, and the film ring remaining on the dragging base plate 3 continues to repeat the above dragging process.
