[0029] refer to Figures 1 to 4 The particle applying device of some embodiments of the present application includes a filter rod core material conveying device 20 and a particle dropping hopper 30. The filter rod core material conveying device 20 includes a plurality of conveying rollers 21 arranged in parallel. Each conveying roller 21 is rotatably arranged to convey the filter rod core material. The particle dropping hopper 30 is arranged above the filter rod core material conveying device 20 and has a dropping port. The dropping port is used to output particles so as to apply the particles to the filter rod core material, wherein the area of the dropping port can be adjusted.
[0030] The discharge port of the particle hopper 30 of the particle applying device of some embodiments of the present application is used to output particles downward, and the filter rod core material is transported below the particle discharge port 30, so that the particles can fall onto the filter rod core material. The filter rod core material is transported under the drive of multiple conveying rollers 21, so the area of the discharge port of the particle discharge port 30 can be adjusted, so that the number of particles falling onto the filter rod core material is adjustable, so the number of particles applied to the filter rod core material can be adjusted, so that the particle applying device of the embodiment of the present application can control the area of the discharge port according to the type of filter rod, and then adjust the number of particles applied to the filter rod core material, so that the particle applying device of the embodiment of the present application can be applied to the production of different types of filter rods, thereby increasing the scope of application.
[0031] The particle applying device of the embodiment of the present application is used to produce filter rods. The filter rod is an important part of cigarettes. The filter rod generally includes a filter rod core material and a forming paper wrapped around the outside of the filter rod core material. The filter rod core material includes acetate fiber tow, paper, polylactic acid fiber, etc. Therefore, the particle applying device of the embodiment of the present application is used to apply particles to the filter rod core material, and the type of the filter rod core material is not limited.
[0032] like Figure 2As shown, the filter rod core material conveying device 20 includes a plurality of conveying rollers 21 arranged in the conveying direction X. The axis of each conveying roller 21 is perpendicular to the conveying direction X. And the plurality of conveying rollers 21 are staggered in the height direction, so that when the filter rod core material is conveyed forward along the conveying direction X by the filter rod core material conveying device 20, the filter rod core material is not conveyed forward in a flat state, but is conveyed forward in a curved surface or an arc surface.
[0033] The particle drop hopper 30 is fixed, that is, its drop opening is also fixed. Therefore, when the filter rod core material is conveyed forward along the conveying direction X, it can receive particles only when it reaches the position corresponding to the drop opening, and then continue to convey forward after receiving the particles.
[0034] refer to Figure 3 In some embodiments, the particle drop hopper 30 includes a hopper body 31 and a plug plate 33. The hopper body 31 has a discharge port at the lower end. The plug plate 33 is movably arranged relative to the hopper body 31 to open at least part of the discharge port to form a drop port.
[0035] like Figure 3 As shown, in some embodiments, the particle drop hopper 30 includes a hopper body 31, and the hopper body 31 includes a cone.
[0036] The hopper body 31 includes a cone structure at the lower end. A discharge port is formed at the lower end of the cone structure. In some embodiments, the discharge port is rectangular. The insert plate 33 is movably arranged relative to the hopper body 31, so that when the insert plate 33 covers the entire discharge port, the discharge port of the hopper body 31 is in a closed state; when the insert plate 33 covers part of the discharge port, the uncovered part of the discharge port forms the discharge port. Therefore, by controlling the movement of the insert plate 33 to adjust the area of the discharge port covered by the insert plate 33, the size of the discharge port can be controlled, and then the amount of discharge can be adjusted.
[0037] In some embodiments, the length direction of the discharge port is perpendicular to the conveying direction X. In this way, the particles discharged from the discharge port can extend in the width direction of the filter rod core material, so that particles can be evenly distributed at various positions of the filter rod core material during the process of conveying the filter rod core material along the conveying direction, thereby improving the uniformity of particle distribution.
[0038] In order to further improve the uniformity of particle distribution, refer to Figure 2 In some embodiments, the particle applying device further comprises a particle conveying device 40 disposed below the drop port. The particle conveying device 40 has a conveying surface for receiving and conveying particles output from the drop port. The conveying direction of the conveying surface is opposite to the conveying direction X of the filter rod core material conveying device 20.
[0039] like Figure 2As shown, the particle conveying device 40 is arranged below the drop-out port. In this way, the particles output from the drop-out port will first fall on the conveying surface of the particle conveying device 40, and then the particles will be conveyed to the filter rod core material under the drive of the particle conveying device 40. The conveying direction X of the filter rod core material conveying device 20 is from right to left. The conveying direction of the particle conveying device 40 is opposite to the conveying direction of the filter rod core material conveying device 20, which is from left to right. In this way, the speed of the particles relative to the filter rod core material when falling can be reduced, avoiding the speed being too fast and unable to adhere to the filter rod core material, thereby allowing the particles to fall evenly on the filter rod core material.
[0040] like Figure 2 As shown, the discharge port of the hopper 30 is located near the left end of the conveying surface of the particle conveying device 40. The particles are discharged from the discharge port of the hopper 30 and fall on the conveying surface, and then transported to the right along with the conveying surface and fall through the right end of the conveying surface to the surface of the filter rod core material.
[0041] In order to further adjust the amount of particles output from the drop hopper 30 to the particle conveying device 40, in some embodiments, the distance between the drop opening and the conveying surface is adjustable. The distance here refers to the height from the drop opening to the conveying surface. This height determines the accumulation height of the particles dropped from the drop opening to the particle conveying device 40, and thus determines the amount of particles output to the particle conveying device 40.
[0042] like Figure 3 As shown, in some embodiments, the particle drop hopper 30 includes a hopper body 31 and a discharge shell 32. The hopper body 31 has a discharge port at the lower end. The discharge shell 32 is telescopically arranged outside the discharge port in the height direction. Figure 3 As shown, the lower end of the hopper body 31 is a square discharge port. The discharge shell 32 is also a square cylinder structure. The discharge shell 32 is telescopically arranged at the lower end of the hopper body 31, so the height between the discharge port and the conveying surface can be adjusted by controlling the telescopic movement of the discharge shell 32.
[0043] In some embodiments, the particles include filter particles, which include adsorbent materials, fragrance-carrying materials, or moisture-retaining materials.
[0044] After receiving the particles, the filter rod core material needs to be gathered together to form a particle filter rod segment. In some embodiments, the particle applying device further includes a gathering device 50. The gathering device 50 is used to gather the filter rod core material output by the filter rod core material conveying device 20 toward the middle. Figure 2 As shown, the filter rod core material continues to be conveyed forward under the conveyance of the filter rod core material conveying device 20 . In the embodiment of the present application, a gathering device 50 is arranged downstream of the filter rod core material conveying device 20 .
[0045] like Figure 4 As shown, in some embodiments, the gathering device 50 includes a bottom wall 51 and two side walls 52 respectively arranged on both sides of the bottom wall 51. In the conveying direction of the filter rod core material, the gap between the two side walls gradually becomes smaller to gather the filter rod core material toward the middle.
[0046] like Figure 4 As shown, the area between the two side walls 52 forms a space for carrying the filter rod core material, so that when the filter rod core material is transported between the gaps of the two side walls 52 along the conveying direction, the two side walls 52 limit the filter rod core material, and the gap between the two side walls 52 gradually becomes smaller, so that the filter rod core material gradually gathers toward the middle to form folds, thereby better adhering particles. The embodiment of the present application uses a gathering device 50 to reduce the drop of particles during the material gathering process.
[0047] like Figure 4 As shown, the side wall 52 includes an arc segment and a plane segment arranged in sequence in the conveying direction of the filter rod core material. The arc segment is close to the middle. The plane segment is arranged downstream in the conveying direction, so that the gap between the two side walls 52 gradually decreases and then remains consistent. In this way, the filter rod core material finally outputted is kept at a consistent width.
[0048] In some embodiments, Figure 1 As shown, the particle applying device further comprises a dust removing device 70. The dust removing device 70 comprises a negative pressure suction pipe, the suction port of which is arranged at the lower side of the outlet end of the conveying surface to suck out the dust in the particles.
[0049] The dust here includes fine particles in powder form. Then, when the filter rod core material enters the tobacco tongue of the forming machine, it is easy to overflow and fall on the joint glue, which will affect the bonding quality of the forming paper, and then cause the filter rod joint to be mixed with particles. The filter rod mixed with particles is easy to cause the filter rod to explode during the cigarette splicing process, making the glue-coated tipping paper unable to effectively wrap and stick to the transfer hub wheel, and the machine needs to be stopped for processing. In the process of unsuccessful filter splicing, a large amount of tobacco is wasted.
[0050] Therefore, in order to solve this problem, the particle applying device of the embodiment of the present application is provided with a dust removal device 70 to suck out fine particles such as dust in the particles, thereby avoiding the problem of the filter rod exploding.
[0051] Moreover, the suction port of the negative pressure suction pipe of this embodiment is arranged on the lower side of the outlet end of the conveying surface, so that the dust is removed from the particles before they are applied to the filter rod core material, thereby effectively ensuring that there is no dust in the particles.
[0052] In some embodiments, the negative pressure of the negative pressure suction pipe can be adjusted. Specifically, the negative pressure of the negative pressure suction pipe can be adjusted according to the dust content in the particles.
[0053] like Figure 1 As shown, in some embodiments, the particle applying device further comprises a body 10. The filter rod core material conveying device 20 and the particle dropping hopper 30 are both arranged inside the body 10. The body 10 has an inner cavity, and the filter rod core material conveying device 20 and the particle dropping hopper 30 are both arranged in the inner cavity of the body 10. And the body 10 is a bearing body of other components of the particle applying device.
[0054] In order to facilitate movement and greatly improve the utilization rate of the device, in some embodiments, a moving wheel 60 is provided on the lower side of the body 10 to enable the body 10 to be movably disposed.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution for protection in the present application.
