Description

Technical Field

[0001] This utility model relates to the field of punching dies, and in particular to a blister pack punching die. Background Technology

[0002] Currently, many medicines are packaged in blister packs (also known as blister packs). Since the blister pack is initially a relatively large blister, it needs to be divided into several smaller blister packs before being individually packaged in a box. Patent publication CN114311072B discloses a device for dividing blister packs. This device relies on a cutting blade for division. This method of dividing with a cutting blade is not only inefficient, but also results in relatively large dimensional errors between different blister packs after division. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a blister pack punching die, which cuts and divides blister packs using a punching method. This not only results in high cutting and dividing efficiency but also minimizes dimensional errors between different blister packs after cutting.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A blister pack punching die includes a first template and a second template. A guide rod is provided on the second template, and the guide rod is slidably engaged with a guide hole on the first template. An extrusion die is provided on the first template, and a bottom template is provided on the second template. A through hole is provided on the bottom template, and the through hole is a passage for the extrusion die.

[0006] In this type of blister pack punching die, a large blister pack is placed between the extrusion die and the bottom die plate. Then, the first die plate moves towards the second die plate, and the extrusion die moves towards the through hole of the bottom die plate. When the extrusion die enters the through hole, the large blister pack can be cut into several independent small blister packs. Therefore, this punching mode cuts and divides the blister pack by punching, which not only has high cutting and dividing efficiency, but also results in relatively small dimensional errors between different blister packs after cutting.

[0007] In this type of punching die, guide rods are provided to guide the movement in order to ensure that the first and second templates remain stable and do not shift when they move relative to each other.

[0008] Optionally, the second template has a material picking hole, which overlaps with the through hole.

[0009] The purpose of setting up the material removal hole is to facilitate the removal of the small medicine blister after it has been punched and formed.

[0010] Optionally, it also includes a guide sleeve, which is disposed in the guide hole of the first template. A retainer is disposed inside the guide sleeve and is sleeved on the guide rod. The retainer and the guide sleeve are slidably engaged.

[0011] The cage's function is to reduce friction between the guide rod and the guide sleeve, ensuring smoother sliding of the guide rod relative to the guide sleeve.

[0012] Optionally, it also includes a limiting screw, one end of which is engaged with the second template, and the limiting screw is slidably engaged with a limiting hole on the first template.

[0013] The specific function of the limiting screw is to prevent the first template from completely separating from the second template by having its end stick to the first template.

[0014] Optionally, the first template is provided with a waste cutter, and the angle between the waste cutter and the second template is 5 degrees to 7 degrees.

[0015] The purpose of the waste cutter is to remove the waste material from the large blister pack after punching.

[0016] Optionally, the second template is provided with a guide plate.

[0017] The function of the guide plate is to facilitate the smooth sliding of waste material. Specifically, the guide plate is arc-shaped.

[0018] Optionally, the extrusion die is parallel to the guide rod.

[0019] Optionally, the guide rod is perpendicular to the first template and the second template, and the first template and the second template are in a parallel state.

[0020] Optionally, there are two guide rods, which are parallel and do not contact each other.

[0021] Optionally, the number of extrusion dies and through holes is equal, and the extrusion surface of the extrusion die is not planar.

[0022] The beneficial effects of this utility model are: cutting and dividing the medicine blister pack by punching not only has high cutting and dividing efficiency, but also relatively small dimensional error between different medicine blister packs after cutting. Attached Figure Description
