Description

Technical Field

[0001] The utility model belongs to the technical field of capsule manufacturing, in particular to a capsule monomer cutting device. Background Art

[0002] A hollow capsule is a container formed by two capsule monomers butted together to form a closed inner cavity. The capsule monomer is a cylindrical body with one end open and the other end closed by an arc surface. It is formed by dipping a cylindrical mold into a glue solution and then taking it out and coating it with the glue solution to solidify it. After forming, it is threshed from the mold to form a capsule monomer with an inner cavity. The length of the formed capsule monomer blank is not uniform, and the end of the open end is not flush. The open end needs to be cut and trimmed to a fixed length to make the capsule monomer standard and flush. Most of the existing capsule cutting machines are single-process equipment, which collects the formed and threshed capsule monomers and puts them into the hopper uniformly. The arranging feeding mechanism receives the capsule monomers from the hopper and feeds them to the cutting mechanism in a quantitative and directional manner. The cutting mechanism sets a groove on the outer wall of the drum to receive the capsule monomer blanks with the center line in a horizontal direction. The outer wall of the drum is provided with a movable top shaft inserted into the capsule cavity to support the capsule, and cooperates with the disc cutting knife to achieve cutting; the arranging feeding mechanism uses a vertical hole (notch) on the outer edge of the disc to receive the vertical drop of the center line of the capsule monomer in the hopper, and then cooperates with the baffle plate to realize the dumping of the capsule monomer from the vertical direction to the horizontal direction, corresponding to the horizontal capsule monomer received by the drum, and realizes the cyclic arrangement and feeding through the rotation of the disc. Such an arranging feeding mechanism is prone to problems of material jamming and inaccurate drop during the process of discharging, feeding and dropping, and the structure is relatively complex.

[0003] The fully automatic production line on the market uses the threshing device to clamp the threshing device and then directly feed the material into the chuck clamping hole of the cutting device for cutting. It is not suitable for the process of threshing and collecting first and then cutting. The fully automatic production line equipment is expensive and the production efficiency is not high, making the equipment cost-effective. Utility Model Content
