Description

TECHNICAL FIELD

[0001] The present application relates to a kind of punching device, specifically to a cigarette with filter longitudinal ventilation hole and its matching punching device. BACKGROUND

[0002] Generally, the cigarette in the filter portion uses online laser punching, rotates 360° to form one or more ventilation holes in the circumferential direction in the middle of the filter, or punches a hole in the range of the cigarette lighting end to achieve the setting of the ventilation degree of the cigarette.

[0003] However, the filter circumferential punching method forms holes in the circumferential direction, and the ventilation band formed by the ring hole is constant distance from the mouth end, and the ventilation degree of the filter is constant during the process of the cigarette burning.

[0004] Chinese patent 201620412747.2 punches the cigarette lighting segment, which arranges the holes along the axial line of the cigarette, compared with the distribution method of the filter circumferential punching, has certain dynamic effect, when the burning length of the cigarette changes after lighting, the ventilation effect of the cigarette also changes. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a device capable of transverse punching.

[0006] The technical solution of the present application to solve the above technical problems is:

[0007] A cigarette with filter longitudinal ventilation hole and its matching high-speed punching device mainly consists of a conveying device for conveying cigarettes and a laser punching device for punching holes on the surface of the specified cigarette, the conveying device mainly consists of a conveying belt and a telescopic sleeve for adsorbing cigarettes standing on the conveying belt, when the telescopic sleeve is conveyed to the working section of the laser punching device, the telescopic part of the telescopic sleeve extends outward horizontally and by a preset length at a preset speed while the telescopic sleeve moves longitudinally following the conveying device.

[0008] The main principle is that the laser punching device cannot move horizontally at high speed due to optical principles and its own weight, and generally performs punching at fixed points or changes the circumferential punching by optical angle refraction, which has no problem, but axial punching cannot be performed, therefore, we design a scheme: since the punching equipment cannot move, let the cigarette move horizontally, simply speaking, the cigarette extends outward horizontally while being conveyed horizontally, as long as the matching speed of the two is controlled (this can be completely realized in the current technical level), a straight hole row can be punched.

[0009] The further defined technical solution of the present application is:

[0010] Further, the telescopic set is one of a screw telescopic set, an electric telescopic set, a hydraulic telescopic set and a sliding telescopic set. The telescopic set is only responsible for pushing the cigarettes outward horizontally at a certain speed, and there is no special requirement, but different outward pushing ways, physical structures and costs are quite different, thus we hope to provide different solutions according to different requirements.

[0011] Further, the telescopic set for adsorbing the cigarettes is a sliding set, which comprises a fixed seat and a hollow shaft slidingly connected to the fixed seat, one end of the hollow shaft is provided with a guide shaft, a through groove communicating with a negative pressure cavity in the fixed seat is formed in the shaft body of the hollow shaft, and a cigarette insertion port is arranged at the other end of the hollow shaft; one side of the transmission device is provided with a guide groove for guiding the movement direction of the guide shaft; when the fixed seat moves forward longitudinally under the driving of the transmission belt, the hollow shaft extends outward horizontally under the constraint of the guide shaft and the guide groove. The sliding set is a non-powered sliding design, which needs to rely on the horizontal moving pulling force and the guide design of the sliding groove to complete the horizontal extension, and the use environment of the present application has the horizontal power source of the conveying belt, thus the two are combined, and the desired technical solution can be obtained, and the solution does not need an additional power source and a control system, only needs to increase the mechanical structure, is relatively safer and more reliable, and the subsequent maintenance cost is greatly reduced.

[0012] Further, the laser drilling device mainly comprises a laser light source, an optical tracking device arranged in the light path of the laser light source, and a focusing mirror arranged in the refraction light path of the optical tracking device, and the focusing mirror converges the laser to the surface of the cigarette.

[0013] Further, the fixed seats are equidistantly distributed on the horizontal conveying belt, and a negative pressure passage penetrating through the seat body is formed in the fixed seat, and the tail of the negative pressure passage is communicated with a negative pressure mechanism; the upper surface of the fixed seat is provided with a slide rail or a tubular cavity for sliding of the hollow shaft, and the two sliding ways are the most common and reliable, and other sliding ways can also be used to replace.

[0014] Further, the guide groove is composed of a slanting section and straight sections connected to both ends of the slanting section, the horizontal projection length of the slanting section is greater than the stroke of the optical tracking device, and the horizontal height difference of the slanting section is consistent with the length of the drilling section.

[0015] Further, the focusing mirror is an arc-shaped columnar mirror or an f-θ field lens.

[0016] Further, the optical tracking device is composed of a single or double shaft galvanometer, or a rotating prism, or a spiral reflector, or other light beam scanning devices.

[0017] Further, for the low speed punching application, the telescopic sleeve is not needed, thus the technical solution can be simplified. The telescopic sleeve for adsorbing the cigarette is a fixed adsorbing sleeve, which comprises a fixed seat and a hollow shaft connected to the fixed seat. One end of the hollow shaft is provided with a guide shaft. The shaft body of the hollow shaft is provided with a through slot communicating with the negative pressure cavity in the fixed seat. The other end of the hollow shaft is provided with a cigarette insertion port.

[0018] Further, the optimal solution is that the optical tracking device is a double-axis galvanometer.

[0019] Further, the transmission belt can be replaced by a conveying chain. It can be understood that there are many horizontal transmission modes, and the application point of the application is not in the horizontal transmission part.

[0020] A cigarette produced by the above-mentioned device has a plurality of air permeable holes distributed along the length direction of the cigarette.

[0021] A cigarette forming device adopts the above-mentioned punching device.

[0022] In summary, the above-mentioned device can quickly produce a cigarette with a filter longitudinal ventilation hole. The filter section of the cigarette is provided with at least one column of holes in the axial direction. By changing the length of the filter entering the oral cavity when the cigarette is smoked, the dynamic ventilation resistance of the cigarette and the setting of the smoke concentration are achieved. A punching device for achieving the dynamic ventilation resistance of the cigarette is also disclosed. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0029] EMBODIMENT

[0030] A cigarette with filter longitudinal ventilation hole and its matching punching device, mainly composed of horizontal conveying device 1 for conveying cigarettes 3 and laser punching device 2 for punching holes on the surface of the cigarettes at the designated horizontal conveying section, the horizontal conveying device 1 is mainly composed of horizontal conveying belt 1.1 and telescopic sleeve 1.2 standing on the horizontal conveying belt, when the telescopic sleeve is conveyed to the working section of the laser punching device 2, the telescopic sleeve extends outward by a preset length at a preset speed while following the movement of the horizontal conveying device 1, and the sliding part of the telescopic sleeve extends to the side of the laser punching device 2.

[0031] Briefly speaking: the telescopic sleeve can be extended outward by a screw rod, or extended outward by electricity or hydraulic pressure, etc. In fact, as long as the equipment can extend outward as required, it can be used or implemented. However, since the equipment is compact, it is generally recommended to be designed as simply as possible, so we prefer a non-powered sliding structure. Its feature is to use the power of the conveying belt and the guide groove guide shaft to realize the axial extension of the cigarette.

[0032] Reference Figure 4 and Figure 5 The sliding sleeve 1.2 includes a fixed seat 1.2.1 and a hollow shaft 1.2.2 slidingly connected to the fixed seat, the fixed seats 1.2.1 are equally distributed on the horizontal conveying belt, and a negative pressure passage 1.3 is opened through the seat body on the fixed seat 1.2.1, the tail of the negative pressure passage 1.3 is connected to a negative pressure mechanism; the upper surface of the fixed seat is provided with a sliding rail 1.2.7 or a tubular cavity 1.2.8 for the hollow shaft to slide, the difference between the two is only the sliding fit relationship, and the others are the same.

[0033] The hollow shaft 1.2.2 has a guide shaft 1.2.3 standing at one end, a through slot is opened in the shaft body of the hollow shaft 1.2.2 to communicate with the negative pressure cavity in the fixed seat 1.2.1, and a cigarette insertion port 1.2.4 is arranged at the other end of the hollow shaft 1.2.2; one side of the horizontal conveying device is provided with a guide groove 1.2.5 for guiding the movement direction of the guide shaft 1.2.3; when the fixed seat 1.2.1 moves forward under the driving of the horizontal conveying belt 1.1, the hollow shaft 1.2.2 extends outward under the constraint of the guide shaft 1.2.3 and the guide groove 1.2.5.

[0034] The guide groove 1.2.5 is set on the guide plate 1.2.6 and is composed of a slanting section and straight sections connected to both ends of the slanting section, so that the guide shaft 1.2.3 will inevitably move laterally when moving in the slanting section. The horizontal projection length of the slanting section is greater than the stroke of the optical tracking device, so as to ensure that the entire punching range is the effective stroke. The horizontal height difference D of the slanting section is consistent with the length of the punching section, which is actually to ensure a gentle slope to ensure the speed of the lateral movement.

[0035] The laser punching device 2 is mainly composed of a laser light source 2.1, an optical tracking device 2.2 set in the light path of the laser light source 2.1, and a focusing mirror 2.3 set in the refractive light path of the optical tracking device 2.2. The focusing mirror 2.3 converges the laser to the surface of the cigarette to complete the punching.

[0036] As an option, the focusing mirror is an arc-shaped cylindrical mirror or an f-θ field lens, or other equivalent optical lens.

[0037] As an option, the optical tracking device is composed of a single or double shaft galvanometer, or a rotating prism, or a spiral reflector, or other equivalent beam scanning devices.

[0038] In addition to the above embodiments, the present application can have other implementation manners. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
