Description

Technical Field

[0001] This utility model relates to the field of dialysis paper packaging technology, and in particular to a feeding and positioning mechanism for heat-sealing packaging of dialysis paper. Background Technology

[0002] Medical packaging dialysis paper is a special material used in medical packaging, primarily for the sterilization and packaging of high-end medical devices. It is typically composed of high-density polyethylene (HDPE) and dialysis paper, with HDPE on one side and dialysis paper on the other. This design allows steam to pass through while preventing bacteria and other microorganisms from entering the packaging, ensuring the sterility of the medical device.

[0003] In the field of medical packaging, blow molding to produce blister packs and heat sealing with dialysis paper is a common aseptic packaging method. Existing packaging equipment has an easy-tear opening in one corner of the heat-sealing area for easy unsealing. This area is usually controlled by the heat-sealing equipment, which leads to high requirements for the temperature control, size and installation progress of the heat-sealing equipment. Moreover, a certain amount of compression will be generated during the heat-sealing process. The lack of necessary support equipment will cause the rotating plate used to switch the heat-sealing processing area to become loose, tilted or even break at the connection point. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a feeding and positioning mechanism for heat-sealing packaging of dialysis paper.

[0005] This utility model is achieved through the following technical solution:

[0006] A feeding and positioning mechanism for heat-sealing packaging of dialysis paper includes a mounting box, a motor, a rotating plate, a support mechanism, a heat-sealing box, and a pad mechanism. The motor is installed inside the bottom of the mounting box, the rotating plate is connected to the output end of the motor, the support mechanism is installed inside the mounting box, the heat-sealing box is fixed to the rotating plate, and the pad mechanism is disposed outside the heat-sealing box. The pad mechanism includes an electric telescopic rod, a moving frame, a mounting base, a guide rod, a spring, and a pad. The moving frame is fixedly disposed at the telescopic end of the electric telescopic rod, the mounting base is fixedly disposed at one end of the moving frame, the guide rod is fixedly disposed inside the mounting base, the spring is sleeved outside the guide rod, and the pad is sleeved outside the guide rod.

[0007] In a preferred embodiment of the present invention, the support mechanism includes a support frame, a limiting frame and ball bearings. The support frame is fixed to the inside of the mounting box, the limiting frame is disposed on the inner bottom and inner top of the support frame, and the ball bearings are engaged inside the limiting frame.

[0008] The support mechanism mainly provides auxiliary support for the edge of the rotating plate, while the ball bearings effectively ensure the normal operation of the rotating plate and reduce friction.

[0009] In a preferred embodiment of this utility model, the outer edge of the rotating plate is engaged between the top ball bearing and the bottom ball bearing of the support frame.

[0010] In a preferred embodiment of this utility model, the electric telescopic rod is installed on the outside of the heat-sealing box, and the surface of the heat-sealing box is provided with a locking hole that cooperates with the pad.

[0011] The pad is positioned between the blister pack and the dialysis paper, preventing some areas from being effectively heat-sealed and creating an opening that is easy to open, thus reducing the requirements for the size and installation accuracy of the heat-sealing equipment.

[0012] In a preferred embodiment of the present invention, a limiting support ring is provided on the inner side of the heat-sealing box, and a pad is provided on the top outer side of the limiting support ring on the inner side of the heat-sealing box.

[0013] In a preferred embodiment of this utility model, the pad is fitted to the inner top of the mounting base, and the spring is disposed at the bottom of the pad;

[0014] Ensure the pad is effectively positioned between the blister pack and the dialysis paper, and automatically fall under pressure when the heat sealing equipment is pressed down, ensuring a good fit and reducing obstruction to the dialysis paper.

[0015] The beneficial effects of this utility model are:

[0016] The feeding and positioning mechanism for heat-sealing dialysis paper effectively supports the edge of the rotating plate of the feeding mechanism, thereby ensuring smooth operation of the rotating plate and preventing it from tilting due to single-point pressure from the heat-sealing equipment. During the heat-sealing process, a pad is placed in one corner between the blister pack and the dialysis paper to facilitate the formation of an easy-tear opening, reducing the requirements for the shape, size, and installation accuracy of the heat-sealing equipment.

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0024] like Figure 1-5 The feeding and positioning mechanism for heat-sealing packaging of dialysis paper shown includes a mounting box 1, a motor 2, a rotating plate 3, a support mechanism 4, a heat-sealing box 5, and a pad mechanism 6. The motor 2 is installed inside the bottom of the mounting box 1, the rotating plate 3 is connected to the output end of the motor 2, the support mechanism 4 is installed inside the mounting box 1, the heat-sealing box 5 is fixed to the rotating plate 3, and the pad mechanism 6 is set outside the heat-sealing box 5. The pad mechanism 6 includes an electric telescopic rod 61, a moving frame 62, a mounting base 63, a guide rod 64, a spring 65, and a pad 66. The moving frame 62 is fixedly set at the telescopic end of the electric telescopic rod 61, the mounting base 63 is fixedly set at one end of the moving frame 62, the guide rod 64 is fixedly set inside the mounting base 63, the spring 65 is sleeved outside the guide rod 64, and the pad 66 is sleeved outside the guide rod 64.

[0025] Specifically, the support mechanism 4 includes a support frame 41, a limiting frame 42, and ball bearings 43. The support frame 41 is fixed to the inside of the mounting box 1. The limiting frame 42 is located on the inner bottom and inner top of the support frame 41. The ball bearings 43 are locked inside the limiting frame 42. The outer edge of the rotating plate 3 is locked between the top ball bearings 43 and the bottom ball bearings 43 of the support frame 41. The electric telescopic rod 61 is installed on the outside of the heat sealing box 5. The surface of the heat sealing box 5 has a locking hole that mates with the pad 66. The inside of the heat sealing box 5 is provided with a limiting support ring. The pad 66 is located on the top outer side of the limiting support ring inside the heat sealing box 5. The pad 66 is in contact with the top inner side of the mounting base 63. The spring 65 is located at the bottom of the pad 66.

[0026] In this embodiment, the blister pack to be heat-sealed is placed inside the heat-sealing box 5. The limiting support ring on the inner side of the heat-sealing box 5 effectively supports the edge of the blister pack. Then, the electric telescopic rod 61 retracts, causing the moving frame 62 at its telescopic end to move backward. The pad 66, which is installed in the mounting base 63, is inserted into the heat-sealing box 5. The pad 66 is set on the top outer side of one end of the blister pack and covers one corner of the blister pack. At this time, the dialysis paper used for packaging is covered on the top of the blister pack.

[0027] Furthermore, driven by motor 2, the rotating plate 3 rotates, conveying the heat-sealing box 5 containing blister packs and dialysis paper to the bottom of the heat-sealing machine. The working end of the heat-sealing equipment descends to heat-seal the edge where the dialysis paper and blister packs are in contact. At this time, the pad 66 is subjected to pressure and slightly descends under the action of guide rod 64. Spring 65 is compressed and contracts. The initial height of pad 66 is higher than that of blister pack, effectively avoiding interference between pad 66 and blister pack when pad 66 extends. After heat sealing is completed, electric telescopic rod 61 extends to pull pad 66 away, and pad 66 automatically returns to its original position under the action of spring 65. During the heat sealing process, support mechanism 4 effectively supports the edge of rotating plate 3. The ball bearings 43, which are movably set on the inner side of support mechanism 4 through limit frame 42, not only effectively support rotating plate 3, but also ensure the normal rotation of rotating plate 3 and reduce friction. Support mechanism 4 avoids tilting and deformation of rotating plate 3 caused by pressure from heat-sealing machine, thereby ensuring heat sealing positioning and heat sealing effect. The rotating heat-sealing box 5 facilitates continuous processing.
