Abstract
Description
Technical Field
[0001] The utility model relates to the field of cigarette production equipment, in particular to a light beam blocking mechanism. Background Art
[0002] Laser punching is an important process in the production process of the tobacco industry. It is generally used to make smoke holes on cigarette packs, filter holes on cigarette packs, logos and patterns on cigarette packs, and to create tiny holes in cigarette paper, regulate the circulation speed and path of smoke in cigarettes, and control the oxygen content in the smoke.
[0003] The application of lasers not only meets production needs, but also has certain risks. When the equipment has occasional failures or equipment maintenance, the laser may cause harm to the operator. This problem has existed for a long time and has not been effectively solved. Therefore, in order to prevent laser harm to operators as much as possible, while setting up other protective devices, a beam blocking mechanism is proposed to solve the above-mentioned problem.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.
[0020] Example: Figure 1-5 As shown, a beam blocking mechanism in this embodiment includes a baffle 1, a cylinder 2 and an air path auxiliary component 3, the baffle 1 is fixedly connected to the cylinder 2, the cylinder 2 is fixedly connected to the external shell 5 of the steering mirror mechanism 4, and two groups of air path auxiliary components 3 are provided on one side of the cylinder 2.
[0021] Among them, the baffle 1 is coated with a special black light-absorbing coating, which can better absorb the energy of the light beam, thereby improving the blocking effect and ensuring that the light beam cannot pass through or penetrate the baffle 1, thereby weakening or eliminating the transmission of the laser beam, and effectively reducing the reflection of light, avoiding the laser beam from reflecting on the surface of the baffle 1 and causing interference or loss.
[0022] Two groups of piston rods are arranged at the top of the cylinder 2, which can evenly control the rise and fall of the baffle 1.
[0023] The baffle 1 is circular in shape, which ensures the uniformity of the laser beam during the blocking process and does not cause deflection or distortion of the laser beam transmission.
[0024] The size of the baffle 1 is larger than the size of the laser light path inlet, which effectively prevents the laser beam leakage from causing harm to the operator.
[0025] In addition, the operation process of the utility model is:
[0026] When it is necessary to block the light beam, the gas enters the cylinder 2 through the gas path auxiliary part 3, causing its piston rod to extend, driving the baffle 1 to rise, and blocking the light beam; when it is not necessary to block, the gas is released through the gas path auxiliary part 3, the piston rod of the cylinder 2 retracts, driving the baffle 1 to descend, and releasing the light beam.
[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0028] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Those skilled in the art should understand that those modifications or equivalent substitutions of the technical solution of the utility model without departing from the purpose and scope of the technical solution should be included in the scope of the claims of the utility model.
