AI Technical Summary
During the cutting process of energetic materials, the uniform and continuous feeding of the drug strip or bundle can cause the cutter to cut at an angle, affecting product quality.
The conveyor belt is controlled by a servo motor to move in a high-frequency stepping mode, and the medicine strips are conveyed in a high-frequency stepping mode. The cutting frequency of the cutter is matched with the conveying frequency of the medicine strips by the program control, so that the medicine strips stop at the moment of cutting. Precise cutting is achieved by using a clamping device and a cutter assembly.
Ensure smooth cut surfaces, improve product quality, and maintain efficient production capacity.

Abstract
Description
Technical Field
[0001] This utility model relates to a high-frequency stepping energetic material cutting device, belonging to the field of energetic drug strip cutting technology. Background Technology
[0002] In the production of energetic materials, dried drug strips and bundles need to be cut into granules of specified lengths. This is typically achieved by either conveying the drug strips at a constant speed and having a cutter reciprocate at a certain frequency to cut the strips or bundles into granules of fixed lengths, or by conveying the drug strips at a constant speed and having a rotary cutter cut them at a certain rotation speed. During this process, because the drug strips are continuously transported forward at a constant speed, the cutting process continues as the strips or bundles move forward, which can cause the granules to have a slanted cut. This slant is more pronounced when cutting larger diameter drug strips, affecting product quality.
[0003] To address the aforementioned issues, a high-frequency stepping energetic material cutting device was designed. This device uses a servo motor to control the conveyor belt to move in a high-frequency stepping manner, thereby controlling the forward transport of the drug strips and bundles in a high-frequency stepping manner. Furthermore, the control program controls the cutting frequency of the cutter to match the drug strip transport frequency, ensuring that the drug strip is stationary at the moment of cutting, preventing oblique cuts and thus improving product quality. Utility Model Content
[0004] The purpose of this invention is to provide a high-frequency stepping energetic material cutting device.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] This utility model discloses a high-frequency stepping energetic material cutting device, which includes a support frame, a conveyor belt disposed on the upper surface of the support frame, a servo motor for driving the conveyor belt, a pressure device and a cutter assembly disposed above the middle of the conveyor belt, and a weighing bucket disposed at the outlet end of the conveyor belt.
[0007] The clamping device is used to clamp the drug strip to be cut, the cutting blade assembly is used to cut the drug strip, and the weighing bucket is used to weigh the drug strip after cutting.
[0008] Work process
[0009] The drug strips to be cut are placed on the conveyor belt, and the servo motor drives the conveyor belt to transport them backward. When the drug strips are transported backward to a position below the clamping device, the servo motor controls the conveyor belt to pause; the clamping device acts to press the drug strips to be cut; at the same time, the cutting assembly acts to cut the drug strips; then the servo motor controls the conveyor belt to run a predetermined distance again and pause again, repeating the pressing and cutting operations until all the drug strips to be cut are completed, and then a new drug strip is placed; the cut drug cartridges continue to be transported backward along the conveyor belt and enter the weighing barrel, where the weighing barrel weighs the drug strips in the barrel, and when the weight reaches a predetermined value, a new weighing barrel is replaced.
[0010] Beneficial effects
[0011] This utility model's high-frequency stepping energetic material cutting device ensures that there is no lateral movement between the drug strip / bundle and the cutter during the cutting process, guaranteeing a flat cut surface without oblique cuts, improving the product quality of the cutting process, and ensuring production capacity through high-frequency stepping.

[0017] The clamping device 4 is used to clamp the medicine strip to be cut, the cutting blade assembly 3 is used to cut the medicine strip, and the weighing bucket 5 is used to weigh the medicine strip after cutting.
[0018] Work process
[0019] The drug strips to be cut are placed on the conveyor belt 6, and the servo motor 1 drives the conveyor belt 6 to convey them backward. When the drug strips to be cut are transported backward to a position below the clamping device 4, the servo motor 1 controls the conveyor belt 6 to stop running; the clamping device 4 acts to clamp the drug strips to be cut; at the same time, the cutting assembly 3 acts to cut the drug strips; then the servo motor 1 controls the conveyor belt 6 to run a predetermined distance again and then stops running again, repeating the clamping and cutting operations until all the drug strips to be cut are completed, and then a new drug strip is placed; the cut drug cartridges continue to be conveyed backward along the conveyor belt 6 and enter the weighing tank 5, where the weighing tank 5 weighs the drug strips in the tank, and when the weight reaches a predetermined value, a new weighing tank 5 is replaced.
