The function of the feeding strip machine is to process the tobacco into a uniform and continuous tobacco bundle with a certain filling density through a series of production processes. Before the continuous tobacco is sent to the rolling and forming machine, it needs to be trimmed into tobacco strips that meet the process quality requirements by a leveler device, and the tobacco trimmed by the leveler device is sent back to the storage area through the wire recycling system of the feeding strip machine to wait for the recycled wire to be reused.
[0003] The wire return system of the YJ17 feeder strip machine is mainly composed of the main wire return device, the auxiliary wire return device, the wire return vibration trough, etc. The discharge end of the auxiliary wire return device is located above the feed end of the main wire return device, and the discharge end of the main wire return device is located above the feed end of the wire return vibration trough. The main and auxiliary wire return conveyor belts convey the trimmed and fallen tobacco to the wire return vibration trough. The wire return vibration trough is connected to the storage area. The wire return vibration trough vibrates periodically and conveys a certain proportion of the trimmed tobacco back to the storage area behind the feeder strip machine. Too much tobacco trimmed by the feeder strip machine causes certain damage to the structure of the tobacco (the proportion of long, short, and broken wire), which is commonly known as the phenomenon of tobacco shredding. The shredding of tobacco is an inevitable phenomenon in the process of mechanically conveying tobacco by the YJ17 feeder strip machine. The shredded tobacco phenomenon will lead to uneven filling of cigarettes, increased weight deviation, and increased empty rate. Quality problems.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0017] like Figures 1 to 6 The present invention provides a new type of tobacco shreds separation and shredding vibration groove. It includes a vibration trough body 1, which is provided with a feeding end and a discharging end. The bottom end surface of the vibration trough body 1 is provided with installation positioning holes Ⅰ2, a rectangular blanking mesh plate 3 with the same width as the vibration trough body 1, a wire dropping port 5 and installation positioning holes Ⅱ6 from right to left. A separation mesh plate 7 connected to the side wall of the vibration trough body 1 is provided above the rectangular blanking mesh plate 3. A baffle connected to the bottom end surface of the vibration trough body 1 is provided at one end of the separation mesh plate 7 close to the wire dropping port 5. A working window 8 that can be flipped open and closed is provided on the surface of the separation mesh plate 7. A guide shell 9 that is tightly connected to the side wall of the vibration trough body 1 is provided below the rectangular blanking mesh plate 3.
[0018] In the embodiment of the present invention, the installation positioning hole I2 and the installation positioning hole II6 can respectively cooperate with the positioning screws to install the vibration trough body 1 at a predetermined position of the entire wire recycling system. The installation positioning hole I2 is located at the feeding end of the vibration trough body 1, and the installation positioning hole II6 is located at the discharging end of the vibration trough body 1. The wire drop port 5 has the function of discharging the shredded tobacco that meets the process requirements separated by the separation mesh plate 7 to the wire storage area. Specifically, the length of the vibration trough body 1 is 1150 mm, the wall thickness is 2 mm, and the width of the outer wall surface is 118 mm.
[0019] In the embodiment of the present invention, the surface of the rectangular blanking mesh plate 3 is provided with a plurality of rectangular mesh holes 4 in a staggered arrangement. The rectangular blanking mesh plate 3 can completely discharge the shredded tobacco that does not meet the process requirements separated by the separation mesh plate 7 from the rectangular mesh holes 4 and guide them into the foam suction box through the guide housing 9. Specifically, the rectangular blanking mesh plate 3 is arranged at a distance of 280 mm from the side wall surface of the feeding end of the vibration trough body 1, and the size of the rectangular blanking mesh plate 3 is 114 mm*70 mm.
[0020] In the embodiment described in the present invention, the separation mesh plate 7 extends from the upper side of the rectangular drop mesh plate 3 to the side wall surface of the feeding end of the vibration trough body 1, and the baffle plate can prevent the shredded tobacco screened by the separation mesh plate 7 from rushing out of the area surrounded by the lower surface of the separation mesh plate 7 and the bottom end surface of the vibration trough body 1 during the vibration conveying process, and then the material is discharged from the drop port 5, and the left and right ends of the baffle plate are respectively connected to the side wall surface of the vibration trough body 1; the surface of the separation mesh plate 7 is evenly provided with a plurality of separation mesh holes in the form of staggered arrangement, the mesh number of the separation mesh holes is 15 meshes, and the diameter of the separation mesh holes is 2.5 mm, and the diameter of the separation mesh holes can meet the requirements for separating shredded tobacco from waste silk in a moving state, and the separation mesh plate 7 can screen the shredded tobacco in the waste silk falling on the surface of the separation mesh plate 7 from the separation mesh holes to the bottom end surface of the vibration trough body 1 under the periodic vibration provided by the external vibration mechanism. Specifically, the length of the separation mesh plate 7 is 400 mm and the thickness is 2 mm. In order to meet the requirement that the shredded tobacco can be normally vibrated and transported, the distance from the lower surface of the separation mesh plate 7 to the bottom end surface of the vibration trough body 1 is set to 8 mm, so that the shredded tobacco screened by the separation mesh plate 7 can be smoothly vibrated and transported to the rectangular blanking mesh plate 3 in the area surrounded by the lower surface of the separation mesh plate 7 and the bottom end surface of the vibration trough body 1, avoiding blockage when the shredded tobacco is vibrated and transported in this area.
[0021] In the embodiment of the present invention, the separation mesh openings on the surface of the separation mesh plate 7 are larger than the rectangular mesh openings 4 on the surface of the rectangular blanking mesh plate 3, so as to ensure that all the shredded tobacco that does not meet the process requirements and falls into the waste tobacco inside the vibration tank body 1 can be separated by the separation mesh plate 7; By setting up a double-layer structure such as a separation mesh plate 7 and a rectangular blanking mesh plate 4, the tobacco shreds that meet the process requirements and the shredded tobacco shreds that do not meet the process requirements can be effectively separated. The tobacco shreds that meet the process requirements are transported to the tobacco storage area to wait for recycling, and the shredded tobacco shreds that do not meet the process requirements are separated by the separation mesh plate 7 and then discharged into the foam suction box through the rectangular blanking mesh plate 3. This not only ensures the filling amount of tobacco shreds that meet the process requirements in the cigarettes, but also reduces the filling amount of shredded tobacco in the cigarettes. At the same time, it also reduces the occurrence of empty cigarettes and foam in cigarettes, and further reduces the occurrence of uneven filling of cigarettes, increased weight deviation, increased empty head rate, etc., so that the whole shred rate filled into the tobacco bundle is kept in the optimal state to the maximum extent, thereby meeting the product process technology requirements.
[0022] In the embodiment of the present invention, the working window 8 is opened on the surface of the separation mesh plate 7 opposite to the location of the installation positioning hole Ⅰ2. In the maintenance state, the working window 8 is flipped up and the positioning screw at the installation positioning hole Ⅰ2 on the bottom end surface of the vibration groove body 1 is rotated to facilitate the removal or installation of the vibration groove body 1 from the wire recycling system. In the working state, the working window 8 is closed so that the upper surface of the working window 8 is kept flush with the upper surface of the separation mesh plate 7, so that the tobacco can maintain normal vibration transportation after falling into the vibration groove body 1 during the wire recycling process.
[0023] In the embodiment of the present invention, the guide shell 9 has the function of receiving the shredded tobacco dropped from the rectangular mesh holes 4 of the rectangular blanking mesh plate 3 and introducing it into the foam suction box through the opening at the bottom thereof, and the guide shell 9 is provided with a guide inlet end and a guide outlet end located below it, and the guide inlet end is provided with a positioning side wall, and a side wing is further provided at the edge of the guide inlet end next to the positioning side wall, and the positioning side wall of the guide shell 9 is fastened to the side wall surface of the vibration groove body 1 by the cooperation of screws and nuts, thereby further fixing the guide shell 9 below the rectangular blanking mesh plate 3 of the vibration groove body 1, and at this time, the side wing located at the guide inlet end is tightly attached to the vibration groove body The guide outlet end of the guide housing 9 faces the direction of the feeding end of the vibration trough body 1, the opening size of the guide outlet end is smaller than the opening size of the guide inlet end, and the guide outlet end is offset to the side by one end relative to the guide inlet end, so that one of the connecting surfaces between the guide inlet end and the guide outlet end is a vertical plane, and the other connecting surfaces are inclined planes. The purpose of this setting method of the connecting surface between the guide inlet end and the guide outlet end is to avoid the support frame that provides support for the vibration trough body 1 to prevent collision with it during the vibration feeding process, and can also achieve the purpose of changing the discharge position of the shredded tobacco. Specifically, the screws and nuts that fasten the guide shell 9 to the bottom end of the vibration groove body 1 are two matching screws and nuts of model M6; the guide shell 9 is made of stainless steel, with a wall thickness of 1mm, a length of the guide inlet end of 128mm, a width of the guide inlet end of 104mm, a width of the guide outlet end of 31mm, an inclination angle of one of the inclined planes between the guide inlet end and the guide outlet end of 52°, and the centerline position of the guide outlet end is offset to the side by 50mm relative to the centerline position of the guide inlet end.
[0024] The present invention also includes determining the motion parameters of the vibration trough body 1, and determining whether the motion state of the vibration trough body 1 meets the working requirements by analyzing the force of the tobacco, which specifically includes: 1. Determination of vibration parameters: (1)Amplitude A The value range of A varies with the excitation mechanism. Usually, for the inertial drive mechanism (eccentric block exciter), medium frequency and medium amplitude should be used, that is, A=0.5-6mm, and 5mm is selected; (2) Mechanical index The mechanical index is the ratio of the maximum acceleration Xmax of the load-bearing tank to the gravity acceleration g, that is, K=4π 2 f 2 A / g In the formula, w = 2πf. To ensure reliable operation of the equipment and extend its service life, K = 3~5 is selected for commonly used inertial vibration equipment, and the mechanical index K = 4 is selected; (3) Excitation frequency When the mechanical index K and amplitude A are determined, f = (gk / 4π 2 A) 0.5 Calculate the excitation frequency; (value range: f = 10 ~ 25Hz equivalent to 600-1500 times / min), from K = 4, A = 5mm, we get f = 14Hz.
[0025] (4) Vibration direction angle The vibration direction angle depends on the purpose of the equipment and the properties of the material. In order to increase the conveying speed, the optimal vibration direction angle corresponds to the mechanical index: when K=4, δ=30-60°, select δ=45°.
[0026] (5) Throwing index D The throw index is the ratio of the vertical component of the maximum acceleration of the bearing vibration trough body 1 to the gravity acceleration g, that is: D=Aω 2 sinσ / gcosα Where α is the inclination angle of the vibrating equipment. In order to make the conveyed material slide in a micro-parabolic state, it is generally taken as 1 <D<3 .3。
[0027] 2. Analysis of the movement of cut tobacco on the vibrating trough body 1 For the force conditions of the materials in the vibrating trough body 1 and the vibrating trough body 1, please refer to Figure 7 ; Vibration direction angle δ: Select 45 degrees; Material throwing index D: From D = Ksinδ, it can be known that D = 4sin45° and D = 2.83; The vibrating trough body 1 performs simple harmonic motion s = Asinwt. From the dynamic equilibrium equation, we can get: N = mgcosα - mssinδ; When the cut tobacco is thrown off the working surface during transportation, the instantaneous positive pressure N = 0.
[0028] D = Aω 2 sinδ / gcosα In the above formula, D = 2.83, A = 0.005m, δ = 45°, ω = √(Kg / A).
[0029] It can be obtained that α = 0°, that is, the vibrating trough body 1 is horizontally arranged.
[0030] When D < 1, the material is relatively stationary or only slides on the vibrating trough body 1; when D > 1, the movement state of the material relative to the vibrating trough body 1 is mainly in a throwing motion state. This can reduce the resistance of the material movement and reduce the wear of the material on the vibrating trough body 1. However, if the throwing motion is too intense, it is easy to break the material or make the conveying state unstable. Generally, 1 < D < 3.3 is taken. Therefore, the calculated D = 2.83 meets the working requirements.
[0031] The present invention also provides a use method of a new type of return wire vibrating trough for separating and crushing cut tobacco, which is applied to the above-mentioned new type of return wire vibrating trough for separating and crushing cut tobacco. The specific steps include: Step S1: Start the equipment Start the external vibration mechanism that provides periodic vibration for the vibrating trough body 1, so that the vibrating trough body 1 is in a working preparation state. At this time, the working window 8 opened on the surface of the vibrating trough body 1 is in a closed state, ensuring that the upper surface of the working window 8 is flush with the upper surface of the separation mesh plate 7, so as to ensure that the cut tobacco can maintain normal vibrating transportation after falling into the vibrating trough body 1 during the return wire process; Step S2: Separate the crushed cut tobacco When the waste tobacco falls onto the surface of the separation mesh plate 7 inside the vibration trough body 1 and vibrates forward from the feeding end of the vibration trough body 1 toward the discharging end of the vibration trough body 1, the tobacco shreds that meet the process requirements in the waste tobacco will be vibrated and transported to the drop port 5 through the upper surface of the separation mesh plate 7 under the action of periodic vibration and then discharged to the designated position, and the shredded tobacco shreds that do not meet the process requirements in the waste tobacco will be screened into the area surrounded by the lower surface of the separation mesh plate 7 and the bottom end surface of the vibration trough body 1 through the separation mesh holes of the separation mesh plate 7 under the action of periodic vibration. Step S3: Discharging shredded tobacco After the shredded tobacco in the waste silk falls into the area enclosed by the lower surface of the separation mesh plate 7 and the bottom end surface of the vibration trough body 1, it continues to move toward the discharge end of the vibration trough body 1 under the action of continuous periodic vibration until the shredded tobacco in the waste silk reaches the rectangular blanking mesh plate 3 located below the separation mesh plate 7. The shredded tobacco will be completely discharged from the rectangular mesh holes 4 of the rectangular blanking mesh plate 3 and introduced to the designated position through the guide housing 9, thereby completing the separation process of the shredded tobacco; Step S4: Equipment maintenance When the separation process of shredded tobacco is completed and the equipment is repaired, the working window 8 is flipped up and the positioning screw used in the installation positioning hole Ⅰ2 on the bottom end surface of the vibration tank body 1 is rotated to facilitate the removal or installation of the vibration tank body 1 from the wire recycling system.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
