Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic bottle cap production, and particularly relates to a blanking machine for plastic bottle cap production. Background Art
[0002] Plastic bottle caps are very common items in daily life and are widely used in the packaging of various products such as beverages, seasonings, cosmetics, and medicines. The main function of plastic bottle caps is to seal containers, prevent the contents from leaking, deteriorating, or being contaminated, and at the same time facilitate consumers to open and reseal. The production process of plastic bottle caps usually includes multiple links such as injection molding, cooling, demolding, ring cutting, padding, etc. The blanking machine plays a role in this stage or a certain stage before it to ensure that raw materials or semi-finished products can be accurately and efficiently put into an injection molding machine or other production equipment according to production requirements.
[0003] Common blanking machines for plastic bottle cap production are usually composed of structures such as a frame, a screening component, a blanking component, a conveying component, and a control component. The screening component screens and classifies raw materials or semi-finished products, the blanking component transports the screened materials or semi-finished products from the screening component to subsequent production processes, and the conveying component transports the bottle caps from the blanking hopper to the capping port or other processing positions.
[0004] For traditional blanking machines for plastic bottle cap production, when the blanking machine conveys raw materials, the raw materials need to have a certain degree of uniformity and consistency. When there are too many impurities, uneven particle sizes, or irregular shapes in the raw materials, it will affect the normal operation of the blanking machine and the production quality of the bottle caps. To solve the above problems, some blanking machines for plastic bottle cap production are provided with a screening component inside the machine, such as a screening mesh plate, etc. When the raw materials pass through the screening component, the raw materials with impurities, uneven particle sizes, or irregular shapes in the raw materials are separated, so that the qualified raw materials pass through the screening component and descend and are transported to the processing link, thus avoiding affecting the normal operation of the blanking machine and the production quality of the bottle caps. However, in this way, since the raw materials with impurities, uneven particle sizes, or irregular shapes are intercepted at the top of the screening component, it will not only hinder the screening of normal raw materials, resulting in a reduction in the screening effect, but also require regular shutdown for cleaning, increasing the maintenance cost and time and affecting production continuity. Therefore, a blanking machine for plastic bottle cap production is proposed. Content of the Utility Model
[0005] (1) Technical Problems to be Solved

[0028] Please refer to Figure 3, the screening mesh plate 8 is arranged at the center of the inner cavity of the equipment housing 1 and is in close contact with the arc-shaped rod 7. Positive conical plates 9 are added to the front and rear ends of the top of the screening mesh plate 8. The screening mesh plate 8 corresponds to the side scraper 11, and receiving concave plates 13 are installed at the lower parts on both sides of the equipment housing 1. The raw materials are introduced into the equipment housing 1 through the feeding funnel 4, and the raw materials are screened by the screening mesh plate 8.
