Description

Technical Field

[0001] This utility model relates to the field of medicine column processing technology, and in particular to a medicine column cutting tool. Background Technology

[0002] Combustion chamber propellant is a solid propellant with a specific geometric shape and size. Currently, the outer surface processing of propellant is mainly done manually using machine tools, requiring multiple employees to operate on-site. The process mainly includes multiple steps such as feeding, product clamping, machine tool processing, product turning, and unloading. The technology is outdated, the labor intensity is high, and the production efficiency is low. At the same time, the processing tools for this product are somewhat dangerous, and the industry has prominent hygiene and safety hazards.

[0003] During workpiece processing, the propellant cartridges need to be cut off. The waste material from the cut cartridges falls off, affecting the processing of other cartridges. For example, patent CN117047477A discloses an automated propellant cartridge cutting equipment and method, including a frame with a fixed material station on the outside. A transfer clamping mechanism is set at the bottom of the fixed material station on the frame. A center clamping mechanism and a chuck clamping mechanism are sequentially arranged directly above the transfer clamping mechanism on the frame. The center clamping mechanism is driven and connected by a center lifting mechanism, which is connected to a center counterweight mechanism. The chuck clamping mechanism is driven and connected by a chuck lifting mechanism, which is connected to a chuck counterweight mechanism. A cutting mechanism is set beside the fixed material station. However, this only provides a propellant cartridge processing clamping and positioning structure; the cut waste material will fall off, posing a risk of affecting the processing of other cartridges.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0025] like Figures 1 to 4 As shown, the cutting tool for cutting medicinal materials includes a tool holder 1, a movable frame 4, a cutting blade 5, a drive cylinder 8 for moving the movable frame, and a gripper mechanism for holding and cutting the medicinal materials. The cutting blade 5 is mounted on the movable frame, which is mounted on the tool holder 1 via a guide rail structure 3. The drive cylinder is mounted on the tool holder, and the gripper mechanism is mounted on the tool holder and located inside the movable frame.

[0026] The guide rail structure of the tool holder 1 is provided with a sliding block 11. The driving part of the driving cylinder is connected to the sliding block. There is a pair of moving frames 4, which are located on opposite sides of the sliding block. The cutting blade is located between one end of the pair of moving frames, and the cutting blade is reliably positioned. The cutting blade is driven by the moving frames on both sides to perform cutting operations. The medicine column cutting tool is used for overall cutting of the medicine column, completing the one-time cutting of most of the medicine column, and realizing efficient processing of the medicine column.

[0027] One end of the tool holder 1 is equipped with a quick-change disc 2 for quick installation or removal from the industrial robot arm; the main structure of the tool is mounted on the quick-change disc, and automatic tool switching is achieved through the quick-change disc.

[0028] The tool holder includes a base plate and end plates fixed at both ends of the base plate. The end plates are equipped with pneumatic switches 9 for controlling the drive cylinder. The pneumatic switches are set with corresponding sliders, ensuring stable and reliable operation; and the structure is compact.

[0029] The guide rail structure is located on one side of the substrate. The gripper mechanism includes a gripper cylinder 12 and a pair of grippers 10 on the gripper cylinder. The gripper cylinder is located on the other side of the substrate. The pair of grippers are arranged opposite each other to ensure that the drug column will not fall during the cutting process. The pair of grippers are located inside a pair of moving frames and the cutting blade. They are built-in and have a compact structure.

[0030] Limiting plates 6 are provided at both ends on the other side of the substrate; furthermore, polyurethane limiting blocks 7 are provided on the inner side of the limiting plates; during processing, they are used to limit the drug column, and the shape of the limiting blocks is manually changed according to the shape of the drug column.

[0031] Furthermore, the substrate is provided with a pushing structure for pushing down the cutting cartridge. Preferably, the pushing structure includes a feeding cylinder 13 and a push block 14 disposed at the piston rod end of the feeding cylinder. The substrate is provided with a positioning groove, the feeding cylinder is disposed in the positioning groove, and the push block is disposed corresponding to the gripper.

[0032] After the drug cartridge is cut, the industrial robot arm moves the cutting tool to the top of the waste bin. A pair of grippers open, and the unloading cylinder drives the pusher block to move downwards. The pusher block smoothly pushes the cut drug cartridge down into the waste area, avoiding the problem of the drug cartridge getting stuck in the grippers and causing poor unloading.

[0033] The utility model of the cutting tool for cutting medicinal materials has a reasonable structural design. It integrates a medicinal material waste clamping structure and a cutting blade structure that do not interfere with each other. The cut waste will not fall off, and the cut medicinal material can be placed in a fixed position, making the processing stable and reliable.
