Description

Technical Field

[0001] The utility model relates to the technical field of tobacco equipment, in particular to a stripping knife roller. Background Art

[0002] Tobacco flakes are dried and then sliced ​​or shredded. The online shredding process is to cut the flakes into the length required by the process, with a width of about 1mm. The shredding method includes first cutting into 1mm wide strips longitudinally and then using a spiral knife to cut into strips of a certain length, or first using a fixed-length cross-cut knife to cut a certain length of staggered cuts on the flakes and then cutting into 1mm wide strips longitudinally. During the cutting process of the spiral knife, the length is not controlled, resulting in a large range of shredded lengths that does not meet the process requirements. Figure 1-2 As shown, Figure 1 It is a schematic diagram of the principle of cutting a typical thin sheet into tobacco shreds of fixed length and width in the prior art; Figure 2 The figure is a schematic diagram of a typical thin sheet cut into fixed length and fixed width tobacco in the prior art.

[0003] Fixed-length crosscut knives can solve the problem of consistent length, but in the process of crosscutting thin slices, the blade of the crosscutting knife roller cuts the thin slices and continues to rotate. The thin slices may get stuck on the blade and roll up with the rotation of the knife roller, causing the thin slices to be unable to enter the longitudinal cutting knife group to complete the shredding. If the thin slices are not handled manually in time after winding, they will become thicker and eventually cause the equipment to shut down, affecting production continuity, and in serious cases, the knife roller will be damaged.

[0004] In the prior art, the following methods are used to remove the slices from the knife roller. The first method is to use elastic foam or the like adhered to the outer surface of the cross-cutting knife roller, with a thickness slightly higher than the height of the blade. The elastic foam is compressed during cross-cutting, and rebounds after cross-cutting to eject the slice stuck on the blade to achieve the purpose of removing the slices. This method is simple, effective and low-cost in other industries, but it cannot be used in the tobacco industry because the foam has a certain elasticity. During the cross-cutting process, it cannot be guaranteed that the blade will come out of the same incision every time, and a slight offset will occur. After a period of use, the blade will cut tiny foam filaments from the elastic foam and mix them into the tobacco. This non-metallic impurity is not easy to detect and remove. In addition, after a long period of use, it will age, break, fall off and mix into the tobacco, which is a huge quality accident for the tobacco industry.

[0005] The second method is to install a set of compressed air blowing pipes under the cross-cutting knife roller, and blow the compressed air to the cross-cutting knife roller at a certain angle, so as to use the airflow to remove the stuck slices from the cross-cutting knife roller. Although this method is clean, its reliability needs to be improved, and it is particularly difficult to adjust. If the pressure is too high, the slices will be blown off and difficult to enter the longitudinal cutter, and if the pressure is too low, it will be difficult to blow the slices off; if the angle is not appropriate, the effect will not be good.

[0006] In summary, how to effectively solve the problem that the thin slices get stuck on the blade and cannot fall off to form a tangled web during the online fixed-length slicing process is an urgent problem that technicians in this field need to solve. Utility Model Content

DETAILED DESCRIPTION

[0047] The core of the utility model is to provide a stripping knife roller, which effectively solves the problem that the thin slices are stuck on the blade and cannot fall off to form winding during the online fixed-length cutting process of the thin slices.

[0048] 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 the embodiments. Based on the embodiments in 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.

[0049] Please refer to Figures 3 to 9 , Figure 3 A schematic diagram of the structure of a stripping knife roller provided in a specific implementation manner of the utility model; Figure 4 is a cross-sectional view of a stripping knife roller; Figure 5 It is the structural schematic diagram of the knife roller; Figure 6 is a cross-sectional view of the knife roller; Figure 7 It is a structural schematic diagram of the air intake disk; Figure 8 is a cross-sectional view of the air intake disc; Fig. 9 Schematic diagram of the cross-cutting knife group.

[0050] During the cross-cutting process of the thin slice 100, the blade of the cross-cutting knife roller 1 cuts the thin slice 100 and continues to rotate. The thin slice 100 may be stuck on the blade and rotate with the knife roller to form a coil, which makes the thin slice 100 unable to enter the longitudinal cutting knife group 300 to complete the shredding. If the thin slice 100 is not handled manually in time after winding, it will become thicker and thicker, and eventually the equipment will stop, affecting production, and in serious cases, it will damage the knife roller. To solve this problem, a new way of shedding the thin slice 100 is adopted, that is, the thin slice 100 is blown off by the internal blowing method.

[0051] Specifically, the stripping knife roller provided by the utility model comprises:

[0052] The cross-cutting knife roller 1 has a plurality of air inlet holes 7 distributed along the circumferential direction on its first end surface, and the air inlet holes 7 extend toward the second end surface of the cross-cutting knife roller 1 to form a plurality of air inlet channels, and the roller surface of the cross-cutting knife roller 1 has a plurality of exhaust holes 8 connected to one of the air inlet channels;

[0053] The air inlet disc 2 is installed at the connecting shaft of the cross-cutting knife roller 1 and is rotatably connected to the cross-cutting knife roller 1. The air inlet disc 2 includes an air inlet 10 connected to the air source and an air delivery port 11 connected to a plurality of air inlet holes 7. The air delivery port 11 is located on the discharge side of the cross-cutting knife roller 1. When working, the cross-cutting knife roller 1 rotates so that the air inlet holes 7 in the circumferential direction are connected to the air delivery port 11 in sequence.

[0054] In the above structure, the stripping knife roller includes a cross-cutting knife roller 1 and an air inlet disc 2. The air inlet disc 2 is installed at the connecting shaft of the cross-cutting knife roller 1. The air inlet disc 2 is connected to the bracket and is relatively stationary. The cross-cutting knife roller 1 is connected to the motor, and the cross-cutting knife roller 1 rotates relative to the air inlet disc 2.

[0055] A plurality of air inlet holes 7 are distributed on the first end surface of the cross-cutting knife roller 1 . The plurality of air inlet holes 7 are distributed along the circumferential direction. Preferably, the plurality of air inlet holes 7 are evenly distributed along the circumferential direction.

[0056] The air inlet disk 2 includes an air inlet 10 and an air delivery port 11. The air inlet 10 is connected to the air source, and compressed air enters the air inlet disk 2 from the air inlet 10. The air delivery port 11 is connected to the air inlet 10, and compressed air enters the air delivery port 11 from the air inlet 10. The air delivery port 11 is located on the side where the cross-cutting knife roller 1 discharges the material. When working, the cross-cutting knife roller 1 rotates so that the air inlet holes 7 in the circumferential direction are connected with the air delivery port 11 in sequence, and the compressed air enters the air inlet holes 7.

[0057] The air inlet 7 extends toward the second end face of the cross-cutting roller 1 to form a plurality of air inlet channels, and preferably, the axial direction of the plurality of air inlet channels is the same as the axial direction of the cross-cutting roller 1. Of course, the axial direction of the air inlet channel may also be different from the axial direction of the cross-cutting roller 1, and the air inlet channel is a spiral channel.

[0058] The roller surface of the cross-cutting knife roller 1 has a plurality of exhaust holes 8, which are connected to one of the air inlet channels. The gas in the air inlet channel is ejected from the exhaust holes 8 to blow off the thin slice 100 that may be stuck on the cross-cutting blade 9 from the knife roller.

[0059] The sheet-removing knife roller provided by the utility model has a simple structure. Compressed air passes through the air inlet disk 2 and is finally sprayed from the exhaust hole 8 to the thin slice 100, so that the thin slice 100 falls off the knife roller without being entangled with the roller. The sheet-removing is achieved by blowing clean compressed air from the inside of the knife roller to the outside, and no foreign matter will be mixed into the tobacco, thereby greatly improving the reliability.

[0060] On the basis of the above-mentioned specific embodiments, the air inlet passage penetrates the transverse cutting roller 1 in the axial direction, the second end surface of the transverse cutting roller 1 has an air inlet hole 7, and both ends of the transverse cutting roller 1 are equipped with air inlet disks 2.

[0061] In a specific embodiment, the air inlet channel is a through channel, which penetrates the cross-cutting knife roller 1 in the axial direction, that is, the second end face of the cross-cutting knife roller 1 has an air inlet hole 7, and the air inlet holes 7 on both end faces are connected.

[0062] At this time, air intake plates 2 are installed at both ends of the cross-cutting knife roller 1, and the compressed air at both ends enters the air intake channel at the same time. The air intake channel takes in air at both ends, shortening the flow path of the compressed air, ensuring that there is sufficient compressed air at the end of the air intake channel and along the entire length, and ensuring that the gas pressure ejected from each exhaust hole 8 is sufficient to blow the thin film 100 stuck on the cross-cutting blade 9 off the knife roller.

[0063] On the basis of the above-mentioned specific embodiments, the axial direction of the air inlet passage is consistent with the axial direction of the transverse cutting roller 1, and exhaust holes 8 are provided on both sides of each transverse blade.

[0064] In a specific embodiment, the air inlet channel is a straight channel, the axial direction of the air inlet channel is consistent with the axial direction of the cross-cutting knife roller 1, and the length of the air inlet channel is short, which further shortens the stroke of the compressed air and ensures that the compressed air pressure ejected from each exhaust hole 8 is relatively high.

[0065] On the basis of the above-mentioned specific embodiments, exhaust holes 8 are provided on both sides of each transverse blade, and two air inlet channels are provided between two adjacent transverse blades of the transverse cutting roller 1 in the circumferential direction.

[0066] In a specific embodiment, in the circumferential direction, an air inlet channel is provided between the two transverse blades, and the air inlet channel may be one, two, or even more, and the number of air inlet channels is determined according to the distance between two adjacent transverse blades. The cross-cutting knife roller 1 has exhaust holes 8 in the axial and circumferential directions, and the exhaust holes 8 are distributed at various positions of the cross-cutting knife roller 1, so as to blow off the slices 100 stuck at different positions of the cross-cutting knife roller 1 from the knife roller.

[0067] Preferably, when the diameter of the cross-cutting knife roller 1 is the same, the diameter of the air inlet channel is reduced by increasing the number of air inlet channels. The smaller the diameter of the air inlet channel, the smaller the diameter of the exhaust hole 8. When the compressed air pressure remains unchanged, the smaller the exhaust hole 8, the greater the pressure, and the more conducive it is to blow the sheet 100 off the knife roller. For example, the diameter of the air inlet channel is 10 mm, and the diameter of the exhaust hole 8 is less than 5 mm, which increases the compressed air pressure.

[0068] On the basis of the above-mentioned specific embodiments, it also includes a main air pipe 3 with one end connected to the compressed gas, a tee 5 with a first port connected to the other end of the main air pipe 3, and two bronchi 6 connected to the second and third ports of the tee 5 respectively, and the other end of the bronchial pipe 6 is connected to the air inlet 10 of the air inlet disk 2.

[0069] In a specific embodiment, one end of the main air pipe 3 is connected to the compressed gas, the first port of the tee 5 is connected to the other end of the main air pipe 3, the two bronchial pipes 6 are respectively connected to the second port and the third port of the tee 5, and the other end of the bronchial pipe 6 is connected to the air inlet 10 of the air inlet disk 2. The tee 5 divides the air path into two paths, which are respectively connected to the air inlet disks 2 at both ends, so that compressed air can enter both ends of the cross-cutting knife roller 1 at the same time, ensuring that the air volume in the entire axial direction of the cross-cutting knife roller 1 is sufficient and the compressed air pressure meets the use requirements.

[0070] Based on the above specific embodiments, it also includes:

[0071] A pressure sensor for detecting the gas pressure in the air inlet disk 2;

[0072] A pressure regulating mechanism 4 connected to the pressure sensor is used to reduce the pressure of the compressed gas when the gas pressure in the air intake disk 2 is greater than a first preset value; and to pressurize the compressed gas when the gas pressure in the air intake disk 2 is less than a second preset value.

[0073] In practical applications, a pressure sensor is provided at the air inlet 10 of the air inlet disk 2 to detect the gas pressure in the air inlet disk 2 .

[0074] The pressure regulating mechanism 4 is connected to the pressure sensor, and the pressure regulating mechanism 4 receives the gas pressure value in the air intake disk 2 sent by the pressure sensor. The pressure regulating mechanism 4 is provided with a first preset value and a second preset value, and the pressure regulating mechanism 4 compares the gas pressure value in the air intake disk 2 with the first preset value and the second preset value. When the gas pressure in the air intake disk 2 is greater than the first preset value, the pressure regulating mechanism 4 decompresses the compressed gas; when the gas pressure in the air intake disk 2 is less than the second preset value, the pressure regulating mechanism 4 pressurizes the compressed gas to ensure that the compressed air pressure entering the air intake disk 2 is appropriate, so as to blow off the thin slice 100 stuck on the cross-cutting blade 9 from the knife roller, and prevent the thin slice 100 from being blown away or shaken greatly due to excessive pressure, so as to ensure that the thin slice 100 can be tangentially along the cutting point of the cross-cutting knife group 200, so as to smoothly enter the longitudinal cutting knife group 300.

[0075] Preferably, the pressure regulating mechanism 4 is a filter pressure reducing valve installed on the main air pipe 3, which can filter the compressed air to prevent debris from entering the air intake passage; and can also adjust the pressure, which is easy to operate and has precise pressure control.

[0076] On the basis of the above-mentioned specific embodiments, an angle adjustment mechanism for adjusting the angle between the gas delivery port 11 and the cutting point of the cross-cutting knife roller 1 is also included.

[0077] In practical applications, the position of the air delivery port 11, that is, the angle between the air delivery port 11 and the cutting point of the cross-cutting knife roller 1, is adjusted by the angle adjustment mechanism to ensure that the slice 100 is sprayed after cross-cutting, reduce the number of empty sprays of compressed air, ensure the accuracy of the spraying timing, improve the utilization rate of compressed air, and improve the spraying efficiency.

[0078] Based on the above specific embodiments, the angle adjustment mechanism includes:

[0079] An angle sensor for detecting the angle between the gas delivery port 11 and the cutting point of the cross-cutting knife roller 1;

[0080] A rotating part connected to the angle sensor, used for rotating the air inlet disk 2 to adjust the air delivery port 11 to within a preset limit angle when the current angle between the air delivery port 11 and the cutting point of the cross-cutting knife roller 1 is greater than a preset limit angle.

[0081] In practical applications, an angle sensor is provided at the gas delivery port 11 of the gas inlet disk 2 to detect the angle between the gas delivery port 11 and the cutting point of the cross-cutting knife roller 1 .

[0082] The rotating part is connected to the angle sensor, and receives the angle information of the cutting point between the gas outlet 11 and the cross-cutting knife roller 1, and compares it with the preset limit angle. When the current angle between the cutting point between the gas outlet 11 and the cross-cutting knife roller 1 is greater than the preset limit angle, it means that the gas outlet 11 is far away from the cutting point. The rotating part rotates the air inlet disk 2 to adjust the gas outlet 11 to within the preset limit angle, ensuring that the gas outlet 11 is close to the cutting point and within the blowing range.

[0083] Preferably, the angle between the air outlet 11 and the cutting point of the cross-cutting knife roller 1 is set at 30°-45°, which is within the standard blowing angle range. The cross-cutting knife roller 1 and the thin film 100 have a small wrap angle, and the compressed air blowing angle is large, which makes it easy to blow the thin film 100 off the knife roller.

[0084] In the above embodiment, the position of the gas delivery port 11 is precisely adjusted by the rotating part and the angle sensor, ensuring that the blowing angle of the gas delivery port 11 is easy to blow the sheet 100 off the knife roller.

[0085] Based on the above specific embodiments, the rotating part includes:

[0086] A receiving unit for receiving angle information of the gas delivery port 11 and the cutting point of the cross-cutting knife roller 1 detected by the angle sensor;

[0087] A judgment unit connected to the receiving unit and used to judge whether the current angle between the gas delivery port 11 and the cutting point of the cross-cutting knife roller 1 is within the standard blowing angle range;

[0088] A calculation unit connected to the judgment unit, for calculating the rotation angle of the air inlet disc 2 according to the current angle between the air delivery port 11 and the cutting point of the cross-cutting knife roller 1;

[0089] A rotation execution unit connected to the calculation unit and used for controlling the rotation of the air intake disc 2 according to the rotation angle calculated by the calculation unit.

[0090] In practical applications, the receiving unit receives the angle information of the gas delivery port 11 and the cutting point of the cross-cutting knife roller 1 detected by the angle sensor, and sends the detected current angle information to the judging unit.

[0091] A standard blowing angle range is set in the judgment unit. The judgment unit compares the current angle between the gas supply port 11 and the cutting point of the cross-cutting knife roller 1 with the standard blowing angle range, judges whether the current angle between the gas supply port 11 and the cutting point of the cross-cutting knife roller 1 is within the standard blowing angle range, and the judgment unit sends the judgment information to the calculation unit.

[0092] The calculation unit receives the judgment information of the judgment unit. If it is within the standard blowing angle range, the calculation unit obtains that the rotation angle of the air inlet disc 2 is zero; if not, the rotation angle of the air inlet disc 2 is calculated based on the current angle between the air delivery port 11 and the cutting point of the cross-cutting knife roller 1.

[0093] The rotation execution unit is connected to the calculation unit, and controls the rotation of the air inlet disk 2 according to the rotation angle calculated by the calculation unit, so as to rotate the angle between the air delivery port 11 and the cutting point of the cross-cutting knife roller 1 to within the standard blowing angle range.

[0094] In the above embodiment, the rotating part rotates the gas delivery port 11 to within the standard blowing angle range, and the position of the gas delivery port 11 is automatically adjusted, which is convenient and accurate to adjust.

[0095] Based on the above specific embodiments, the rotation execution unit includes:

[0096] A power assembly for providing power;

[0097] A transmission assembly connected to the power assembly for realizing the rotation of the air intake disc 2.

[0098] In practical applications, the power assembly provides power, such as a telescopic cylinder, which does not pollute the sheet 100, has low cost and fast response speed. Of course, it can also be an oil cylinder or an electric push rod, all of which are within the protection scope of the utility model.

[0099] One end of the transmission assembly is connected to the power assembly, and the other end is connected to the air intake disc 2. The power is transmitted to the air intake disc 2 through the transmission assembly to realize the rotation of the air intake disc 2. Specifically, the air intake disc 2 and the cross-cutting knife roller 1 are connected through a bearing, and the telescopic cylinder is connected to the ear plate of the air intake disc 2. The telescopic cylinder telescopically drives the air intake disc 2 to rotate relative to the rotating cross-cutting knife roller 1 at a set angle, which has a simple structure and convenient connection.

[0100] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
