[0037] The first direction A can refer to Figure 1 and Figure 2 The second direction B can be referred to as Figure 2 The direction shown is perpendicular to the first direction A.

[0038] The embodiment of the present disclosure provides a shredder, which includes: a roller cutter 10, a blowing device 1 and a driving device. The roller cutter 10 extends along a first direction A and is configured to cut tobacco leaves. The blowing device 1 includes at least one nozzle, which is configured to spray a cleaning airflow for cleaning the roller cutter 10 to the roller cutter 10. The driving device is connected to the blowing device 1 and is configured to drive the blowing device 1 to change its posture so as to adjust the position and / or direction of the nozzle relative to the roller cutter 10.

[0039] The driving device may include, for example, an actuator, such as a motor, a hydraulic cylinder, etc. The actuator is directly connected to the blowing device 1 to drive the blowing device 1 to move or rotate. The actuator may, for example, drive the blowing device 1 to move along a certain direction. Figure 2 The first direction A shown is moved to change the position of the nozzle relative to the roller cutter 10 along the first direction A, so as to facilitate the clean airflow to clean the axial edge of the roller cutter 10. The actuating part can also drive the blowing device 1 to rotate around the axial direction of the blowing device 1 to change the direction of the nozzle relative to the roller cutter 10, so as to facilitate changing the blowing position of the blowing device 1. If the actuating part drives the blowing device 1 to swing back and forth, the clean airflow can also form a dynamic blowing process, so that the tobacco leaves are more easily peeled off the roller cutter 10. The driving device can further include a transmission part arranged between the actuating part and the blowing device 1, and the transmission part can include, for example, a gear rack mechanism, a threaded screw mechanism, a connecting rod mechanism, etc.

[0040] The shredder may include a protective cover covering the roller cutter 10 and the blowing device 1. This arrangement is helpful to prevent the stripped tobacco leaves from being blown around by the clean airflow.

[0041] By providing a blowing device 1 including at least one nozzle, and providing a driving device connected to the blowing device 1, the blowing device 1 is driven to change its posture to adjust the position and / or direction of the nozzle relative to the roller cutter 10. This arrangement is conducive to the driving device changing the blowing angle of the blowing device 1, so that the clean airflow can clean the tobacco leaves adhering to different positions of the roller cutter 10, increase the blowing area and amplitude, thereby maintaining the cutting surface of the roller cutter clean, so as to improve the cutting quality of tobacco shreds, and at the same time, it is conducive to changing the direction of the clean airflow after the tobacco leaves are peeled off the roller cutter 10, so that the tobacco shreds fall more smoothly, and there is no need to manually stop the machine to clean the roller cutter 10, which is also conducive to improving production efficiency.

[0042] In some embodiments, the shredder includes: two roller cutters 10 and two blowing devices 1. The two roller cutters 10 are arranged side by side along a second direction B perpendicular to the first direction A, and the two roller cutters 10 rotate in opposite directions so that the tobacco leaves pass between the two roller cutters 10.

[0043] like Figure 1 As shown, the first direction A corresponds to Figure 1 The left and right directions shown are also Figure 1 The left and right direction of the material box 2 of the middle cutting machine. Figure 2 As shown, the two roller cutters 10 can be arranged side by side along the second direction B, and the second direction B corresponds to Figure 2 In some embodiments, the Figure 2 The roller cutter 10 on the left side rotates clockwise and is located Figure 2 The roller cutter 10 on the middle right side rotates counterclockwise, and the tobacco leaves can fall downwards between the two roller cutters 10 onto the unloading plate 22 .

[0044] The two blowing devices 1 are respectively installed on both sides of the two roller cutters 10 along the second direction B. The driving device is connected to the two blowing devices 1 and is configured to drive at least one of the two blowing devices 1 to translate and / or rotate around an axis extending along the first direction A to adjust the position and / or direction of the nozzle relative to the two roller cutters 10.

[0045] For example, Figure 1 As shown, the two blowing devices 1 may include a first blowing device 1A and a second blowing device 1B, and the driving device may drive the first blowing device 1A or the second blowing device 1B to change its position, or may drive the first blowing device 1A and the second blowing device 1B to change their position at the same time. For another example, the driving device may drive one of the first blowing device 1A and the second blowing device 1B to move in translation, and drive the other to rotate. The driving device may drive the first blowing device 1A and / or the second blowing device 1B to move in translation along the first direction A, or may drive them to move in translation along any direction perpendicular to the first direction A, for example, to move in translation along the second direction B, so as to approach or move away from the two roller cutters 10, so as to facilitate the nozzle to approach the position where the tobacco leaves adhere to the roller cutter 10, and to align the tobacco leaves for cleaning. For another example, the driving device can drive the blowing device 1 to rotate to change the blowing angle of the nozzle, which is beneficial to change the direction of the clean airflow after it is blown out from the nozzle, so that the adhered tobacco leaves leave the surface of the roller cutter 10 and fall downward to the unloading plate 22 located under the two roller cutters 10 through the clean airflow, thereby preventing the tobacco leaves from flying and polluting the environment.

[0046] It should be understood that the above examples are only for illustrative purposes, and other embodiments of the present disclosure should not be limited thereto. After combining the drawings, description and claims of the present disclosure, it should be obvious to those skilled in the art that according to the present invention, other variations of the driving device for driving the two blowing devices 1 in any combination of translation direction, posture change state (including translation or rotation) and the number of blowing devices 1 driven by the driving device can be made.

[0047] The above arrangement is conducive to enabling the blowing device to blow the tobacco leaves adhering to the roller cutter 10 in a targeted manner, so as to improve the utilization rate of the clean airflow, save energy, and improve the cleaning efficiency of the blowing device 1. In addition, the driving device can drive the blowing device 1 to move in a direction away from the roller cutter 10, which is convenient for the staff to perform daily maintenance and repair on the roller cutter 10, so that the blowing device 1 will not block the staff's work.

[0048] In some embodiments, at least one nozzle of the blowing device 1 includes a plurality of first nozzles 1a, and the plurality of first nozzles 1a are arranged in a row along the first direction A. Figure 2 and 3 As shown, the blowing device 1 may include a first body 11 and a first nozzle 1a. The first body 11 includes a blowing pipe 111 and a plurality of tube columns 112 arranged on the blowing pipe 111. The plurality of tube columns 112 are arranged in rows and spaced apart along the first direction A on the blowing pipe 111, and the central hole of each tube column 112 is connected to the central hole of the blowing pipe 111. The opening of the central hole of each tube column 112 away from the blowing pipe 111 forms a first nozzle 1a. The cross section of the first nozzle 1a is circular. Compared with the nozzle arranged flush with the outer surface of the blowing pipe 111, this arrangement is more conducive to guiding the injection direction of the clean airflow, and is also conducive to concentrating the clean airflow to form a stronger impact force on the tobacco leaves adhered to the roller cutter 10, which helps to more effectively peel off the attached tobacco leaves.

[0049] The radial dimension of the center hole of the tube column 112, that is, the radial dimension of the first nozzle 1a can be one-third to one-quarter of the radial dimension of the center hole of the blow tube 111. This arrangement is beneficial to reducing the diffusion of the airflow at the first nozzle 1a, so that the force generated by the clean airflow can act more concentratedly on the tobacco leaves, and at the same time is beneficial to reducing the air pressure of the input clean airflow.

[0050] In addition, in an embodiment not shown in the figure, the cross-sectional shape of the first nozzle 1a can be a square, an ellipse, a triangle or other geometric shapes.

[0051] A plurality of first nozzles 1a are arranged and spaced apart along the first direction A to form a row of first nozzles 1a, which is beneficial to increasing the cleaning force and cleaning range, so that the cleaning airflow can clean the area adhering to the edge of the roller cutter 10 close to the first direction A.

[0052] In some embodiments, at least one nozzle of the blowing device 1 includes a plurality of rows of first nozzles 1a, and each row of first nozzles 1a is arranged at intervals along the circumference of the blowing device 1. Figure 4 As shown, two rows of first nozzles 1a are arranged along the circumference of the blowing device 1, and the first nozzles 1a in different rows have different directions, and the first nozzles 1a in each row can be arranged in pairs along the first direction A. In an embodiment not shown in the figure, three or more rows of first nozzles 1a can also be arranged; the first nozzles 1a in each row can also be arranged in a staggered manner, which is conducive to increasing the cleaning range of the cleaning airflow.

[0053] This arrangement is beneficial for increasing the number of nozzles without changing the overall structural dimensions of the blowing device 1, while increasing the blowing range of the blowing device 1, thereby facilitating faster blowing of tobacco leaves adhered to the roller cutter 10 when the driving device drives the blowing device 1 to rotate, and is particularly beneficial for cleaning tobacco leaves adhered to the lower portion of the roller cutter 10.

[0054] In some embodiments, at least one nozzle of the blowing device 1 includes a second nozzle, and the second nozzle is configured as a narrow and long opening extending along the first direction A. The size of the second nozzle along the circumferential direction of the blowing device 1 can be, for example, one-third to one-quarter of the circumferential size of the blowing device 1, and the second nozzle can be arranged in the middle of the blowing device 1 along the first direction A, and the size of the second nozzle along the first direction A can be two-thirds to four-fifths of the size of the blowing device 1 along the first direction A.

[0055] On the one hand, this arrangement helps the cleaning air flow to form a linear airflow extending continuously along the axial direction of the roller cutter 10 at the second nozzle, thereby helping the blowing device 1 to increase the sweeping area. On the other hand, the structural arrangement of the second nozzle is easy to process, thereby helping to reduce manufacturing costs.

[0056] In some embodiments, the at least one nozzle of the blowing device 1 includes two or more second nozzles, and the two or more second nozzles are arranged at intervals along the circumference of the blowing device 1 .

[0057] This arrangement is advantageous in increasing the number of nozzles without changing the overall structural dimensions of the spray device 1, while increasing the blowing amplitude of the spray device 1. Moreover, compared with the case where only one second nozzle is provided, when the driving device drives the spray device 1 to rotate, multiple second nozzles simultaneously spray clean airflows, which is advantageous in increasing the blowing force acting on the tobacco leaves.

[0058] In some embodiments, the shredder further comprises an air source 6, which is connected to the blowing device 1 and is configured to provide a clean air flow to the blowing device 1. The pressure of the air source 6 is adjustable. For example, the air source 6 may comprise a pressure gauge and a compressor, and the initial pressure of the clean air flow may be detected in real time by the pressure gauge, and the compressor parameters may be adjusted based on the detection result of the pressure gauge to adjust the initial pressure of the clean air flow. The air source 6 may also be a gas tank.

[0059] Setting the pressure of the air source 6 to be adjustable is conducive to maintaining the pressure of the clean airflow within an appropriate range, thereby helping to avoid the situation where the blowing force of the clean airflow at the nozzle is too small to effectively clean the tobacco leaves adhering to the roller cutter 10, or the situation where the blowing force of the clean airflow at the nozzle is too large to drop the tobacco leaves. In addition, setting the pressure of the air source 6 to be adjustable is conducive to appropriately increasing the initial pressure of the clean airflow when there are two or more blowing devices 1, thereby avoiding the situation where the pressure of the clean airflow entering each blowing device is too small due to diversion, and the tobacco leaves adhering to the roller cutter 10 cannot be effectively cleaned.

[0060] In some embodiments, the shredder further comprises a pressure reducing device, which is installed between the air source 6 and the blowing device 1 and is configured to adjust the pressure of the cleaning airflow.

[0061] This arrangement is beneficial for reducing the gas pressure when the pressure of the clean airflow provided by the air source 6 is too high, thereby helping to maintain the gas pressure of the clean airflow output from the blowing device 1, avoiding excessive gas pressure from blowing the tobacco leaves into the space outside the shredder and causing environmental pollution or requiring staff to clean the ground additionally, thereby increasing the cleaning work.

[0062] In some embodiments, the pressure reducing device comprises an air filter pressure reducing device 4. Figure 5 As shown, the air filter pressure reducer 4 is in communication with the air source 6 and is configured to adjust the air pressure of the clean air flow and filter the clean air flow before the clean air flow enters the first blowing device 1A and the second blowing device 1B.

[0063] This arrangement is conducive to filtering impurities in the clean air flow, preventing impurities from clogging the nozzle and reducing the cleaning efficiency. In addition, this arrangement is conducive to using one device to achieve air pressure regulation and filtering at the same time, which is conducive to reducing the number of equipment, reducing maintenance costs, and reducing space occupation.

[0064] In some embodiments, the shredder further comprises a flow control device, which is configured to adjust the flow of the cleaning airflow entering the blowing device 1 .

[0065] This arrangement is conducive to adjusting the clean air flow to a suitable flow before entering the blowing device 1, reducing the gas flow when the flow of the clean air flow provided by the air source 6 is too large, thereby avoiding wasting the clean air flow, or increasing the gas flow when the flow of the clean air flow is too small to maintain the gas pressure ejected from the nozzle.

[0066] In some embodiments, the shredder includes more than two blowing devices 1. The flow control device includes a first flow control unit and a second flow control unit. The first flow control unit is configured to adjust the total flow of the clean airflow entering the more than two blowing devices 1. The second flow control unit is configured to adjust the flow of the clean airflow entering each blowing device 1.

[0067] For example, Figure 5 As shown, the first flow control unit can be a manual ball valve 3. Opening the manual ball valve 3 allows the clean air flow to flow into the first blowing device 1A and the second blowing device 1B; closing the manual ball valve 3 can adjust the flow of the clean air flow to zero; turning the handle of the manual ball valve 3 can adjust the total flow of the clean air flow. For another example, the second flow control unit can be a three-way valve, which is connected to the air source 6, the first blowing device 1A and the second blowing device 1B respectively. The total flow of the clean air flow input by the air source 6 can be distributed to the first blowing device 1A and the second blowing device 1B through the three-way valve. The three-way valve can make the flow of the clean air flow input to the first blowing device 1A and the second blowing device 1B the same, or different. This setting is conducive to adjusting the flow size of each blowing device 1 according to the tobacco leaf adhesion of each of the multiple roller cutters 10, so as to improve the controllability and cleaning efficiency of cleaning.

[0068] The first flow control unit is provided to adjust the flow of the clean airflow in general, thereby facilitating efficient use of the clean airflow and avoiding waste of the clean airflow. The second flow control unit is provided to accurately control the flow of the clean airflow input to each blowing device 1, thereby facilitating adjusting the flow of the clean airflow sprayed from a single blowing device 1 when the tobacco leaf adhesion conditions on multiple roller cutters 10 are inconsistent, performing targeted cleaning, and further improving the cleaning efficiency.

[0069] On the other hand, an embodiment of the present disclosure provides a silk making system, which includes the silk cutting machine provided by an embodiment of the present disclosure.

[0070] The silk-making system of the disclosed embodiment has the advantages of the silk-cutting machine of the disclosed embodiment. The cleaning process of the silk-cutting machine does not need to be stopped, which is conducive to improving the production efficiency of the silk-making system.

[0071] The following combination Figures 1 to 5 The wire cutter of the embodiment of the present disclosure and the method for cleaning the wire cutter by the blowing device 1 are described in detail. Figure 1 , Figure 2 and Figure 5 As shown, the shredder includes a material box 2, two roller cutters 10, two blowing devices 1 (including a first blowing device 1A and a second blowing device 1B), a driving device, a protective cover (not shown), an air source 6, an air filter pressure reducer 4, a manual ball valve 3 and a three-way joint 5.

[0072] like Figure 3 In the embodiment shown, the blowing device 1 has a first body 11 and a first nozzle 1a. The first body 11 includes a blowing pipe 111 extending along a first direction A and a plurality of pipe columns 112 arranged on the blowing pipe 111. Figure 4 As shown, the pipe columns 112 form two rows, and the pipe columns 112 in each row (for example, 9 in number) are arranged at intervals along the first direction A. The two rows of pipe columns 112 are arranged at intervals around the circumference of the injection pipe 111. The central hole of each pipe column 112 is connected to the central hole of the injection pipe 111, and the orifice on one side away from the injection pipe 111 forms a first nozzle 1a.

[0073] Thus, the plurality of first nozzles 1a are distributed in two rows along the circumference of the blowing tube 111, and the number of first nozzles 1a in each row is the same as the number of corresponding rows of pipe columns 112 (e.g., 9) and are arranged at intervals along the first direction A. This arrangement is conducive to increasing the blowing amplitude of the first blowing device 1A.

[0074] like Figure 1 and Figure 2 As shown, the driving device is connected to the first blowing device 1A and the second blowing device 1B, and drives the first blowing device 1A and the second blowing device 1B to rotate. The driving device can drive the first blowing device 1A and the second blowing device 1B to rotate simultaneously, or can drive one of the first blowing device 1A and the second blowing device 1B to rotate, so as to change the blowing angle of the first nozzle 1a on the first blowing device 1A and the second blowing device 1B respectively, so as to facilitate targeted cleaning of the positions on the two roller cutters 10 where tobacco leaves are adhered. In addition, the setting of the first nozzle 1a is conducive to the concentration of the clean airflow blown out, which is more convenient to control and more environmentally friendly than the cleaning method of the air gun.

[0075] The material box 2 includes a square box body and four brackets 21. The four brackets 21 are respectively located at the four corners of the box body. The first blowing device 1A and the second blowing device 1B are respectively installed on two of the four brackets 21 along the first direction A, so that the first blowing device 1A and the second blowing device 1B are respectively located on both sides of the two roller cutters 10 along the second direction B. The material box 2 also includes a material discharge plate 22, which is arranged below the two roller cutters 10. The shield is arranged on the top of the box body and forms a closed space with the box body (not shown), which is conducive to all tobacco leaves peeled off from the roller cutters 10 falling into the box body.

[0076] like Figure 5 As shown, in this embodiment, the air source 6 is connected with the air filter pressure reducer 4, the manual ball valve 3, the three-way joint 5 and the two blowing devices 1 in sequence. The air source 6 includes a pressure gauge and a compressor, and the compressor produces a clean airflow and makes the clean airflow have a pressure that can be passed to the nozzle of the blowing device 1. The air filter pressure reducer 4 filters the clean airflow and can reduce the air pressure of the clean airflow, so as to reduce the pressure of the clean airflow to a first pressure range. Within the first pressure range, the clean airflow is delivered to the first nozzle 1a and sprayed out without damaging or scattering the tobacco leaves.

[0077] The clean air flow is first provided to the air filter pressure reducer 4 by the air source 6, and then passes into the manual ball valve 3 after being reduced in pressure and filtered by the air filter pressure reducer 4, and then is divided into two ways from the manual ball valve 3 through the three-way joint 5 and respectively passes into the two blowing devices 1, and finally is sprayed out from the first nozzles 1a of the two blowing devices 1.

[0078] According to the following Figure 5 Specific instructions for cleaning the shredder:

[0079] First open the manual ball valve 3, then open the air source 6;

[0080] Observe the air pressure value of the barometer of the air source 6 and adjust the initial pressure of the air source 6;

[0081] According to the position of tobacco leaves attached to the roller cutter 10, the driving device drives the first blowing device 1A and the second blowing device 1B to rotate or translate respectively, so that the spray direction of the clean airflow is aimed at the tobacco leaves;

[0082] The handle of the manual ball valve 3 is turned to adjust the total flow of the clean airflow. This arrangement is conducive to simplifying the operation. The flow of the clean airflow sprayed from the first nozzles 1a of the two spraying devices 1 can be adjusted by simply adjusting the manual ball valve 3;

[0083] After use, first close the air source 6 and then close the manual ball valve 3.
