Description

Technical Field

[0001] The utility model relates to the technical field of cigarette detection, in particular to a cigarette bursting bead high-speed counter. Background Art

[0002] With the development of the tobacco industry, the demand and quality of new tobacco materials are showing an upward trend. Among them, the use of popping beads in new tobacco has a wide range of applications. In order to improve the production process and detection technology of popping beads for tobacco, the number of popping beads needs to be accurately counted in the production and packaging process to improve the quantity standard of each box of popping bead products. It is necessary to use accurate counting methods to ensure the uniform quantity standard of each box of popping bead products. Now a high-accuracy counting device is needed to provide a counting function for the packaging of popping bead products. At the same time, it provides data reference for the production packaging process and the material loading and unloading process;

[0003] The existing detection methods for cigarette bursting beads are:

[0004] 1. Counting by hand with the help of simple tools;

[0005] 2. Machine vision method, using image method to count them through machine vision detection;

[0006] 3. Count the samples roughly by weighing and dividing them equally;

[0007] The disadvantages of existing detection methods are:

[0008] 1. Counting is done manually with the help of simple tools. This method is inefficient, labor-intensive, and has poor accuracy for large numbers.

[0009] 2. The disadvantages of the machine vision method are high cost, high requirements for mechanical complexity, high requirements for software compatibility, and single requirements for product diameter and color, which cannot achieve compatibility of various samples under the same parameters;

[0010] 3. Approximately count the samples by the weighing and equal distribution method. Weigh a box of samples to get the total weight, then weigh the weight of a single bursting bead, and divide the total weight by the weight of a single bursting bead to get the approximate number of bursting beads in a box. This method can be used as long as each bursting bead is the same weight, but there is still a certain error.

[0011] Therefore, it is necessary to develop a high-speed counter for cigarette explosion beads to solve the above problems. Utility Model Content
