Description

Technical Field

[0001] The utility model relates to the technical field of blister machines, in particular to feeding equipment of blister machines. Background Art

[0002] Blister forming is a type of plastics processing technology. Its main principle is to heat and soften a flat plastic sheet, then vacuum it onto a mold surface and cool it down to form the final product. Blister forming products are widely used in various industries, including electronics, electrical appliances, food, hardware tools, cosmetics, toys, daily necessities, pharmaceuticals, health products, automobiles, stationery, and sports supplies.

[0003] Blister machines are one of the commonly used equipment for blister processing. In order to save human resources, automatic feeding equipment for blister machines has appeared on the market. However, most of the feeding equipment currently used to convey plastic coils on the market only uses laser sensors to detect the tension of plastic coils. Laser sensors are prone to not sensing thinner plastic coils, resulting in a low yield rate. In addition, due to the lack of positioning parts, the plastic coils are prone to deviation during transportation, resulting in low positioning accuracy. Utility Model Content

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

Two lower sensors 502 are provided, a deceleration sensor 601 and a slidable slider 7 are provided on the slide rail 6, the upper sensor 401, the lower sensor 502 and the deceleration sensor 601 are all coordinated with the slider 7, a positioning groove 701 is provided on the side wall of the slider 7 away from the slide rail 6, a rotatable vertical shaft 702 is provided in the positioning groove 701, an upper positioning member 703 and a lower positioning member 704 are provided on the vertical shaft 702, and a positioning space 705 is formed between the vertical shaft 702, the upper positioning member 703 and the lower positioning member 704;

[0020] The material storage reel 1 is used to store plastic coils. After the plastic coil passes through the positioning space 705, it enters the feed roller 2, and the feed roller 2 conveys the plastic coil to the blister machine. The positioning space 705 limits the movement of the plastic coil to the left and right, which can prevent the plastic coil from deviating and improve the positioning accuracy. When the processing starts, the material storage drive device drives the material storage reel 1 to work and convey the plastic coil to the feed roller 2. At this time, the plastic coil drives the slider 7 to descend. When the slider 7 passes the deceleration sensor 601 during the descent process, the material storage drive device slows down the rotation speed of the material storage reel 1. When the slider 7 descends and touches the lower sensor 502, the material storage drive device stops driving the material storage reel 1 to work, and then the feed roller 2 conveys the plastic coil to the blister machine. At this time, the plastic coil drives the slider 7 to rise. When the slider 7 rises and touches the upper sensor 401, the material storage drive device starts driving the material storage reel 1 to work. The positioning detection device 3 can sense the tension of the thinner plastic coil and improve the yield rate.

[0021] In this embodiment, buffer members 706 are provided at both the upper and lower ends of the slider 7 to prevent the slider 7 from being damaged when it comes into contact with the upper sensor 401 and the lower sensor 502 .

[0022] In this embodiment, a bracket 101 is provided at the side end of the storage reel 1 , and a first rod 102 is provided on the bracket 101 . The first rod 102 lifts the plastic coil on one side of the storage reel 1 .
