Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a hollow filter rod detection device. Background Art

[0002] On the one hand, the hollow filter rod can reduce the consumption of the filter rod forming paper. On the other hand, it has a novel appearance, high recognition and anti-counterfeiting functions. Therefore, the application of the hollow filter rod in cigarettes is becoming more and more extensive.

[0003] During the cigarette production process, after connecting the filter tip with the cut tobacco, the outer layer is wrapped with tipping paper, and then the filter tip is cut into single cigarettes, and finally the cigarettes are packaged. During the packaging process, the end face of the cigarette filter tip is photographed and analyzed and detected, and the whole box of cigarettes with deformed inner hole shape or broken hollow filter rods is removed. However, during the process of rubbing and wrapping the tipping paper, the hollow filter rod section will be squeezed, rubbed and cut, and the hollow filter rod is very likely to have problems such as inner hole deformation or even breakage. If the hollow filter rod is detected again during the cigarette packaging process, the whole box of cigarettes with deformed inner hole shape or broken hollow filter rods will be removed, resulting in waste of cigarettes and certain economic losses. Therefore, there is an urgent need for a hollow filter rod detection device to detect the hollow filter rod after extrusion, rubbing and cutting before the hollow filter rod is used, and determine whether it meets the conditions for production on the machine.

[0041] The following will be combined with Figure 1 and further illustrate the technical solutions of the present utility model through specific embodiments.

[0042] With the increasing development of cigarette production technology, the hollow filter rod 10, as a new type of hollow filter rod, can improve the sensory experience and the smoking taste, and is more and more widely used in cigarettes. During the cigarette production process, after connecting the filter tip with the tobacco, the outer layer is wrapped with tipping paper, and then the filter tip is cut into single cigarettes, and finally the cigarettes are packaged. During the packaging process, the end face of the cigarette filter tip is photographed and analyzed and detected, and the whole box of cigarettes with deformed or cracked inner hole shapes of the hollow filter rod 10 is removed. However, during the cigarette production process, when tipping paper is rubbed and joined, the hollow filter rod 10 will be squeezed, rubbed and cut, and the hollow filter rod 10 is extremely prone to problems such as inner hole deformation or even rupture. If the hollow filter rod 10 is further detected during the cigarette packaging process, the whole box of cigarettes with deformed or cracked inner hole shapes of the hollow filter rod 10 will be removed, resulting in waste of cigarettes and certain economic losses.

[0043] To solve the above problems, an embodiment of the present utility model provides a hollow filter rod detection device, which includes a base 1, an upper rubbing plate 2, a lower rubbing plate 3, a conveying mechanism 4 and a cutting mechanism 5. The upper rubbing plate 2 is fixedly arranged on the base 1, the lower rubbing plate 3 is arranged below the upper rubbing plate 2, the upper surface of the lower rubbing plate 3 and the lower surface of the upper rubbing plate 2 are arranged opposite to each other, and the distance therebetween is less than the diameter of the hollow filter rod 10. The upper surface of the lower rubbing plate 3 is provided with first teeth 31 distributed in a first direction; the conveying mechanism 4 is arranged below the lower rubbing plate 3 and can drive the lower rubbing plate 3 to move in the first direction; the cutting mechanism 5 is arranged at one end of the lower rubbing plate 3 and is used for cutting the hollow filter rod 10 after extrusion and rubbing, and then detecting the end face quality of the cut hollow filter rod 10. After simulating the process of rubbing and joining tipping paper by extruding, rubbing and cutting the hollow filter rod 10, and then detecting the hollow filter rod 10 after extrusion, rubbing and cutting, the quality of the hollow filter rod 10 is ensured and the cigarette quality is improved.

[0044] In order to further ensure the accuracy of the detection of the hollow filter rod 10, the hollow filter rod detection device in this embodiment further includes a detection mechanism, which can photograph the end face of the hollow filter rod 10 and perform image comparison and analysis, so as to judge whether there are phenomena such as deformation and rupture in the inner hole of the hollow filter rod 10. The detection method of the hollow filter rod 10 is not limited to this, and it can also be through manual observation and other methods.

[0045] Specifically, when detecting the hollow filter rod 10, the hollow filter rod 10 is placed between the upper rubbing plate 2 and the lower rubbing plate 3, the conveying mechanism 4 drives the lower rubbing plate 3 to move in the first direction, so that the upper rubbing plate 2 and the lower rubbing plate 3 extrude and rub the hollow filter rod 10, and then the cutting mechanism 5 cuts the hollow filter rod 10 after extrusion and rubbing, and then detects the hollow filter rod 10. The qualified hollow filter rods 10 are transferred to the next process for processing, and the unqualified ones are removed, thus ensuring the quality of the hollow filter rod 10 and further improving the cigarette quality.

[0046] In order to achieve the effect of squeezing the hollow filter rod 10, the distance between the upper rubbing plate 2 and the lower rubbing plate 3 should be smaller than the diameter of the hollow filter rod 10. In this embodiment, the distance between the upper rubbing plate 2 and the lower rubbing plate 3 is 2-4 mm smaller than the diameter of the hollow filter rod 10. Exemplarily, the distance between the upper rubbing plate 2 and the lower rubbing plate 3 is 2 mm, 3 mm, or 4 mm smaller than the diameter of the hollow filter rod 10.

[0047] Preferably, in this embodiment, a second tooth 21 is provided on the lower surface of the lower rubbing plate 3, which increases the friction between the hollow filter rod 10 and the upper rubbing plate 2 and the lower rubbing plate 3, enables the upper rubbing plate 2 and the lower rubbing plate 3 to better rub and wrap the hollow filter rod 10, and improves the accuracy of the hollow filter rod detection device.

[0048] In this embodiment, the second teeth 21 are distributed in the second direction, and the second direction is perpendicular to the first direction, that is, the tooth shapes of the first teeth 31 and the second teeth 21 are perpendicular to each other, which increases the friction between the hollow filter rod 10 and the upper rubbing plate 2 and the lower rubbing plate 3. Further, both the first teeth 31 and the second teeth 21 are straight teeth, the tooth pitch is 0.5-1.5 mm. Exemplarily, the tooth pitch can be 0.5 mm, 1 mm, or 1.5 mm; the tooth height is 0.5-1.5 mm. Exemplarily, the tooth height can be 0.5 mm, 1 mm, or 1.5 mm; the tooth shape angle is 50°-70°. Exemplarily, the tooth shape angle can be 50°, 60°, or 70°, which improves the effect of the hollow filter rod detection device in rubbing and wrapping the hollow filter rod 10.

[0049] In order to achieve continuous extrusion and rubbing of multiple hollow filter rods 10, as Figure 1 shown, a plurality of grooves 32 are provided on the upper surface of the lower rubbing plate 3. The depth of the grooves 32 is smaller than the diameter of the hollow filter rod 10 and is used to place the hollow filter rod 10 to prevent the hollow filter rod from sliding on the lower rubbing plate 3. A stop bar 22 is provided at one end of the upper rubbing plate 2 away from the cutting mechanism 5. The stop bar 22 extends out of the lower surface of the upper rubbing plate 2 and is used to pick out the hollow filter rod 10 from the groove 32 to the side of the groove 32 opposite to the moving direction of the lower rubbing plate 3 and allows it to enter between the upper rubbing plate 2 and the lower rubbing plate 3 under the drive of the lower rubbing plate 3. Specifically, when the hollow filter rod 10 moves to contact the stop bar 22, the stop bar 22 applies a force opposite to the moving direction of the hollow filter rod 10 to the hollow filter rod 10, and the hollow filter rod 10 slides out of the groove 32. During this process, the lower rubbing plate 3 continues to move in the first direction. Under the drive of the lower rubbing plate 3, the hollow filter rod 10 enters between the upper rubbing plate 2 and the lower rubbing plate 3. Moreover, the lower rubbing plate 3 moves relative to the upper rubbing plate 2 in the first direction, and the hollow filter rod 10 rolls on the lower rubbing plate 3. As the lower rubbing plate 3 continues to move in the first direction, the hollow filter rod 10 rolls into another adjacent groove 32, that is, the groove 32 on the side opposite to the moving direction of the lower rubbing plate 3, and then the cutting mechanism 5 cuts the hollow filter rod. It should be particularly noted that while the hollow filter rod 10 slides out of the groove, the lower rubbing plate 3 drives the hollow filter rod 10 to enter between the upper rubbing plate 2 and the lower rubbing plate 3.

[0050] Preferably, the maximum width of the groove 32 is designed according to the diameter of the hollow filter rod 10, and the depth of the groove 32 is 1 / 3 of the diameter of the hollow filter rod 10.

[0051] Furthermore, when the lower rubbing plate 3 moves in the first direction, in order to stably place the hollow filter rod 10 in the groove 32, a negative pressure hole 33 is provided in the bottom wall of the groove 32. The negative pressure holes 33 are arranged in one-to-one correspondence with the grooves 32. The negative pressure holes 33 are connected to an air extraction device to form negative pressure in the holes, so as to stably adsorb the hollow filter rod 10 in the groove 32. The air extraction device is a prior art and will not be elaborated here.

[0052] As Figure 1 shown, in this embodiment, the conveying mechanism 4 includes a conveyor belt 41, a guide rail 42, and a slider 43. The conveyor belt 41 is located below the lower rubbing plate 3. The guide rail 42 is arranged between the lower rubbing plate 3 and the conveyor belt 41. The guide rail 42 is distributed in the first direction. The slider 43 is fixedly arranged on the conveyor belt 41, and the lower rubbing plate 3 is fixedly arranged on the slider 43. The slider 42 is slidably connected to the slide rail 42. Driven by the conveyor belt 41, the slider 43 can slide on the guide rail 42 in the first direction, thereby driving the lower rubbing plate 3 to move in the first direction. The sliding speed of the conveyor belt 41 can be adjusted in the range of 0 - 600 m / min. The guide rail 42 and the slider 43 are prior arts and will not be elaborated here.

[0053] In this embodiment, the position of the upper rubbing plate 2 on the base 1 in the vertical direction can be adjusted to make the hollow filter rod detection device adapt to hollow filter rods 10 with different diameters. Preferably, a vertical slide rail 11 is provided on the base 1, and the upper rubbing plate 2 is slidably arranged on the slide rail 11. By adjusting the position of the upper rubbing plate 2 on the base 1, the distance between the upper rubbing plate 2 and the lower rubbing plate 3 is adjusted to make the hollow filter rod detection device applicable to hollow filter rods 10 with different diameters.

[0054] Preferably, the cutting mechanism 5 includes a blade 51, and the blade 51 can cut the hollow filter rod 10 after extrusion and rubbing, so as to realize the inspection of the inner hole shape of the hollow filter rod 10.

[0055] The following details the specific extrusion, rubbing, and cutting processes of the hollow filter rod detection device for the hollow filter rod 10 in this embodiment:

[0056] A plurality of hollow filter rods 10 to be detected are placed at intervals in the grooves 32 on the lower rubbing plate 3. The distance between the upper rubbing plate 2 and the lower rubbing plate 3 is adjusted according to the diameter of the hollow filter rod 10. The conveyor belt 41 moves in the first direction and drives the hollow filter rods 10 on the lower rubbing plate 3 to move in the first direction at the same time. When the hollow filter rod 10 moves to contact the stop bar 22, the hollow filter rod 10 slides out of the groove 32 and enters between the upper rubbing plate 2 and the lower rubbing plate 3 under the drive of the lower rubbing plate 3. The upper rubbing plate 2 and the lower rubbing plate 3 squeeze and rub the hollow filter rod 10. After the hollow filter rod 10 slides a distance of 2-3 times the circumferential length on the lower rubbing plate, the hollow filter rod 10 slides into another adjacent groove 32 again. The cutting mechanism 5 cuts the squeezed and rubbed hollow filter rod 10. By simulating the process of the hollow filter rod 10 being spliced with tipping paper, the end face of the cut hollow filter rod 10 is detected to judge whether the shape of the inner hole has changed.

[0057] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
