Abstract
Description
Technical Field
[0001] This invention relates to the field of tobacco machinery technology, specifically to a follow-type slicer and a slicing method. Background Technology
[0002] In the rapid development of the tobacco processing industry, the slicing machine, as one of the core pieces of equipment on the cigarette production line, is used to slice extruded tobacco blocks to ensure that the tobacco sheets can smoothly enter the subsequent loosening and rehydration stages, thereby improving the hygroscopicity and processing performance of the tobacco. The performance and efficiency of the slicing machine are directly related to the stability and efficiency of the entire production process. Traditionally, the slicing machines widely used in tobacco processing are mainly divided into two categories: vertical and horizontal. In actual production, both types have a problem: material stagnation during the slicing operation. Specifically, when the slicing machine cuts the tobacco blocks, the continuous conveying of the tobacco blocks must be temporarily interrupted. The conveying can only be resumed after the cutting is completed and the tobacco sheets are separated. This discontinuous material handling method not only leads to poor material flow on the production line, which can easily cause fluctuations in the feed of subsequent processing equipment (such as loosening machines and rehydration machines), thus affecting the uniformity and stability of tobacco quality, but also significantly reduces overall production efficiency and increases production costs and energy consumption. Summary of the Invention
[0003] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a follow-up slicer and slicing method that can slice materials during material movement without stopping the material, thus effectively improving work efficiency.
[0004] To achieve the above objectives, the present invention provides a follow-type slicer, including a conveying device and a cutting device. The cutting device includes a cutter, a cutting drive mechanism for driving the cutter to move linearly, and a synchronous drive device, a position detection device, and a control system. The conveying device includes a first conveyor, a second conveyor, and a cutting table. Both the first and second conveyors are linearly conveying along the X-direction, and the first conveyor is positioned in front of the second conveyor along the conveying direction. The cutting table is positioned between the first and second conveyors and is capable of accommodating the insertion of the cutter. The cutter of the cutting device is located above the second conveyor, and... The cutter moves vertically up and down along the Z direction, which is perpendicular to the X direction. The synchronous drive device is connected to the cutting device and can drive the cutting device to reciprocate linearly along the X direction. The position detection device is communicatively connected to the control system and includes a detection light generator set on the side of the first conveyor. The detection light generator can emit detection light towards the first conveyor, and when the detection light is blocked by material on the first conveyor, the position detection device will emit a corresponding signal. The detection light emitted by the detection light generator is perpendicular to the X direction and the detection light is less than the thickness of the cutter. The control system is connected to both the cutting device and the synchronous drive device.
[0005] Furthermore, it also includes a floating pressure plate device, which includes a movable plate, a lifting mechanism mounted on the movable plate, a pressure plate mounted on the lifting mechanism, and a linkage mechanism. The floating pressure plate device is connected to the cutting device through the linkage mechanism, so that the pressure plate can reciprocate synchronously with the cutting device along the X direction. The lifting mechanism can drive the pressure plate to move vertically up and down along the Z direction. The pressure plate is located in front of the cutter of the cutting device.
[0006] Furthermore, the floating pressure plate device also includes a first guide mechanism disposed between the pressure plate and the moving plate, the first guide mechanism being used to guide the pressure plate to move linearly up and down along the Z direction.
[0007] Furthermore, it also includes a fixed frame, the cutting device includes a cutting frame, the cutting frame is installed on the fixed frame and can reciprocate along the conveying direction of the first conveyor, the cutter and the cutting drive mechanism are both installed on the cutting frame and move synchronously with the cutting frame, the cutting frame is provided with an elongated slot extending linearly along the Z direction, the linkage mechanism of the floating pressure plate device includes a linkage rod fixed on the pressure plate, the linkage rod is installed in the elongated slot, the linkage rod is clearance-fitted with the two sides of the elongated slot, and can move linearly up and down in the elongated slot along the Z direction.
[0008] Furthermore, it includes a second guide mechanism disposed between the cutting frame and the fixed frame, the second guide mechanism being used to guide the cutting frame to reciprocate linearly along the X direction.
[0009] Furthermore, the linkage has a guide roller, which is located in an elongated groove.
[0010] Furthermore, the floating pressure plate device includes a connecting frame fixedly installed on the fixed frame and a third guide mechanism disposed on the connecting frame. The moving plate is connected to the third guide mechanism, and the moving plate can reciprocate linearly along the X direction relative to the connecting frame through the third guide mechanism.
[0011] Furthermore, the synchronous drive device includes a synchronous power cylinder fixedly mounted on a fixed frame, wherein the piston rod of the synchronous power cylinder is along the X direction and fixedly connected to the cutting frame.
[0012] Furthermore, the position detection device includes a detection light receiver, which is disposed opposite to the detection light generator on both sides of the second conveyor and is capable of receiving detection light emitted by the detection light generator. Material on the second conveyor can enter between the detection light receiver and the detection light generator.
[0013] The present invention also provides a follow-up slicing method, which uses the above-mentioned follow-up slicer and includes the following steps:
[0014] S1. When the cutting device is in the initial state, the cutter is located on the upper side of the second conveyor; the first and second conveyors convey at the same conveying speed. The material to be sliced enters the second conveyor and the second conveyor conveys the material on it to the first conveyor.
[0015] S2. When the front end of the material to be sliced reaches the detection light emitted by the detection light generator of the position detection device, the position detection device sends a signal to the control system as a slicing working signal.
[0016] S3, Slicing:
[0017] S31. Cutting action: After receiving the signal to start the cutting action, the control system controls the synchronous drive device to move along the X direction at the same speed as the material. At the same time, the control system controls the cutting drive mechanism of the cutting device to move the cutter downward in a straight line towards the second conveyor. The cutter cuts the material, and when the cutter moves to the cutting table, the cutter passes through the material to be sliced and inserts into the cutting table, cutting the material to be sliced. The material slices are obtained on the front side of the cutter, and the material on the rear side of the cutter is reformed into the material to be sliced.
[0018] S32. Reset action: The cutting device first moves in the same direction and at the same speed as the material. The cutting drive mechanism drives the cutter to move upward and retracts the cutter. Then the control system controls the synchronous drive device to reverse the action and drive the cutting device to move along the X direction toward the side where the second conveyor is located. The cutting device returns to the initial state. At this time, the front end of the material to be sliced has not been reached.
[0019] S4. Repeat steps S2 to S3 to continuously slice the material.
[0020] As described above, the follow-up slicer and slicing method of the present invention have the following beneficial effects:
[0021] By setting up a synchronous drive device, a position detection device, a first conveyor, a second conveyor, and a cutting table, the position detection device detects the material position and uses it as a signal to start slicing. The control system automatically controls the synchronous drive device to move the cutting device at the same speed and in the same direction as the material, so that the cutter moves synchronously with the material while cutting downwards. Slicing can be completed during the material conveying process. At the same time, the remaining slices can be automatically detected and sliced again, thereby achieving continuous automatic slicing, effectively improving work efficiency. It can be applied to the cutting of tobacco blocks, reducing tobacco fragmentation and improving the overall processing quality. Attached Figure Description

[0059] See Figures 1 to 7 This invention provides a follow-up slicer, including a conveying device 1 and a cutting device 2. The cutting device 2 includes a cutter 21 and a cutting drive mechanism for driving the cutter 21 to move linearly. It also includes a synchronous drive device 3, a position detection device 7, and a control system. The conveying device 1 includes a first conveyor 11, a second conveyor 12, and a cutting platform 13. Both the first conveyor 11 and the second conveyor 12 convey linearly along the X direction, and the first conveyor 11 is located in front of the second conveyor 12 along the conveying direction. The X direction can be horizontal or slightly inclined to the horizontal plane. The cutting platform 13 is located between the first conveyor 11 and the second conveyor 12 and can accommodate the insertion of the cutter 21. The width of the cutting platform 13 in the X direction is selected as a smaller value according to the actual situation, so as not to affect the material 6 on the second conveyor 12 from crossing the cutting platform 13 to enter the first conveyor 11. The cutter 21 of the cutting device 2 is located above the second conveyor 12, and the cutter 21 moves vertically up and down along the Z direction perpendicular to the X direction. The synchronous drive device 3 is connected to the cutting device 2 and can drive the cutting device 2 to reciprocate linearly along the X direction. The position detection device 7 is connected to the control system. The position detection device 7 adopts photoelectric detection and includes a detection light generator 71 set on the side of the first conveyor 11. The detection light generator 71 can emit detection light towards the first conveyor 11. When the detection light is blocked by the material 6 on the first conveyor 11, the position detection device 7 will emit a corresponding signal. The detection light emitted by the detection light generator 71 is perpendicular to the X direction and the detection light is less than the thickness of the cutter 21, that is, the detection light can pass through the cutting gap generated when the cutter 21 cuts in the material 6. The control system is connected to both the cutting device 2 and the synchronous drive device 3.
[0060] The following-type slicer of this invention is capable of slicing various materials 6, especially for slicing tobacco blocks in tobacco production. In the initial stage of use, the cutting device 2 is positioned at a suitable location on the second conveyor 12, and the cutter 21 is in a retracted state, located at a suitable height above the second conveyor 12. The second conveyor 12 and the first conveyor 11 convey at the same speed. After the material 6 to be sliced enters the second conveyor 12, it is conveyed forward by the second conveyor 12 and crosses the cutting platform 13 to enter the first conveyor 11. When the front end of the material 6 to be sliced reaches the detection light emitted by the detection light generator 71 of the position detection device 7, the position detection device 7 sends a signal to the control system to start the cutting action. At this time, the control system controls the following-type slicer to start one slicing operation, first performing a cutting action. Specifically, the control system controls the synchronous drive device 3 to operate, driving... The cutting device 2 moves along the X direction in the same direction and at the same speed as the material 6. Simultaneously, the cutting drive mechanism of the cutting device 2 is activated, driving the cutter 21 to move downwards in a straight line towards the second conveyor 12. Thus, the cutter 21 moves synchronously with the material 6 while cutting it downwards. The downward speed and conveying speed of the cutter 21 are carefully controlled so that when the cutter 21 moves to the cutting platform 13 in the X direction, it passes through the material 6 to be sliced and inserts into the cutting platform 13, cutting the material 6. This avoids damage to the first and second conveyor channels 11 and 12 by the cutter 21. The front side of the cutter 21 receives... Material 6 is sliced, and the portion of material 6 behind the cutter 21 is reformed into material 6 to be sliced. Then, the cutting device 2 is reset. The cutting device 2 first moves in the same direction and at the same speed as the material 6. The cutting drive mechanism drives the cutter 21 to move upward and retract the cutter 21. At this time, the cutter 21 and the detection light generator 71 still have a certain distance in the X direction. Then, the control system controls the synchronous drive device 3 to reverse the action, driving the cutting device 2 to move backward along the X direction (i.e., the side where the second conveyor 12 is located). The cutting device 2 returns to its initial state. The reset action of the cutting device 2 is relatively fast. At this point, the front end of the material 6 to be sliced has not yet reached the detection light emitted by the detection light generator 71, and the detection light emitted by the detection light generator 71 is still blocked by the previously sliced material 6. During the conveying process, there is a cutting gap formed by the cutter 21 between the material 6 to be sliced and the material 6 slice in front of it. When the cutting gap reaches the detection light, the detection light is no longer blocked, so the previous slicing operation signal of the position detection device 7 stops. Subsequently, when the front end of the material 6 to be sliced reaches the detection light emitted by the detection light generator 71, the next slicing operation is started. During the continuous process of material 6, the slicing operation is continuously performed according to the start cutting action signal of the position detection device 7, and the material 6 does not need to stop, thereby effectively improving the slicing efficiency.
[0061] See Figures 1 to 7The present invention will be further described below with reference to a specific embodiment:
[0062] In this embodiment, see Figure 1 and Figure 3 As a preferred design, in this embodiment, both the first conveyor 11 and the second conveyor 12 are horizontal, that is, the X direction is horizontal, and the Z direction of movement of the cutter 21 is vertical. In other embodiments, the X direction may also be tilted at a certain angle relative to the horizontal plane.
[0063] In this embodiment, see Figure 2 , Figure 3 and Figure 7 As a preferred design, the following slicer also includes a floating pressure plate device 4. The floating pressure plate device 4 includes a moving plate 41, a lifting mechanism mounted on the moving plate 41, a pressure plate 43 mounted on the lifting mechanism, and a linkage mechanism. The floating pressure plate device 4 is connected to the cutting device 2 through the linkage mechanism, so that the pressure plate 43 moves synchronously with the cutting device 2 along the X direction. The lifting mechanism can drive the pressure plate 43 to move vertically up and down along the Z direction. The pressure plate 43 is located in front of the cutter 21 of the cutting device 2. In use, when the cutter 21 of the cutting device 2 moves forward and downward to cut the material 6, the pressure plate 43 also moves forward synchronously. At the same time, the lifting mechanism drives the pressure plate 43 to move downward along the X direction, pressing on the material 6 slice located in front of the cutter 21, thereby stabilizing the position of the material 6 slice, facilitating the cutter 21 to cut the material 6, and the cutter 21 to reset and be pulled out. After the cutter 21 pulls the material 6 out upward, the lifting mechanism drives the pressure plate 43 to reset upward.
[0064] In this embodiment, see Figure 7 As a preferred design, the floating pressure plate device 4 also includes a first guide mechanism 45 disposed between the pressure plate 43 and the moving plate 41. The first guide mechanism 45 is used to guide the pressure plate 43 to move linearly up and down along the Z direction. The first guide mechanism 45 adopts a guide rod and a sliding sleeve in combination, or other forms may be adopted.
[0065] In this embodiment, see Figure 1 and Figure 2 As a preferred design, it also includes a fixed frame 5, and the conveying device 1, the cutting device 2, the synchronous drive device 3, the floating pressure plate device 4 and the position detection device 7 are all installed on the fixed frame 5.
[0066] In this embodiment, see Figure 1 , Figure 5 and Figure 6As a preferred design, the cutting device 2 includes a cutting frame 24, which is mounted on the fixed frame 5 and can reciprocate along the conveying direction of the first conveyor 11. The cutter 21 and the cutting drive mechanism are both mounted on the cutting frame 24 and move synchronously with it. A second guide mechanism 8 is located between the cutting frame 24 and the fixed frame 5. This second guide mechanism 8 guides the cutting frame 24 to reciprocate linearly along the X direction. The second guide mechanism 8 can be a combination of a linear guide rail and a slider, or other suitable forms. Three second guide mechanisms 8 are provided, respectively connecting the two sides and the top of the cutting frame 24.
[0067] In this embodiment, see Figure 5 The cutting device 2 can adopt an existing design, wherein the cutting drive mechanism includes a cutting drive motor 23 and a transmission component 22 connecting the cutting drive motor 23 and the cutter 21. The transmission component 22 can specifically adopt an existing suitable structure. When the cutting drive motor 23 rotates, it drives the cutter 21 to move up and down linearly through the transmission component 22.
[0068] In this embodiment, see Figure 3 , Figure 5 and Figure 7 As a preferred design, the cutting frame 24 of the cutting device 2 is provided with an elongated slot 241 extending linearly along the Z direction. The linkage mechanism of the floating pressure plate device 4 includes a linkage rod 44 fixed to the pressure plate 43. The linkage rod 44 is installed in the elongated slot 241, and the linkage rod 44 is clearance-fitted with both sides of the elongated slot 241. It can move linearly up and down in the Z direction within the elongated slot 241. Preferably, the linkage rod 44 has a guide roller 441 that cooperates with the elongated slot 241, and the guide roller 441 is located in the elongated slot 241. When the cutting device 2 moves in the X direction, the cutting frame 24 drives the linkage rod 44 to move in the X direction through the elongated slot 241, thereby driving the pressure plate 43 and the moving plate 41 to move synchronously in the X direction. The pressure plate 43 can move up and down in the Z direction. At this time, the linkage rod 44 moves up and down in the elongated slot 241, and the guide roller 441 rolls relative to the elongated slot 241 to reduce frictional resistance. In addition, in other embodiments, the linkage mechanism may also take other suitable forms, such as directly connecting the moving plate 41 to the cutting frame 24.
[0069] In this embodiment, see Figure 3 and Figure 7The floating pressure plate device 4 includes a connecting frame 46 fixedly installed on the fixed frame 5, and a third guide mechanism 47 disposed on the connecting frame 46. A movable plate 41 is connected to the third guide mechanism 47, and the movable plate 41 can reciprocate linearly along the X direction relative to the connecting frame 46 via the third guide mechanism 47. The third guide mechanism 47 adopts a combination of a linear guide rail and a slider, or other suitable forms. The third guide mechanism 47 guides the linear movement of the movable plate 41 and the pressure plate 43 in the X direction for stable guidance. In this embodiment, the lifting mechanism includes a lifting power cylinder 42 fixed to the movable plate 41. The lifting power cylinder 42 can specifically be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. Its piston rod is fixedly connected to the pressure plate 43, resulting in a simple, stable, and reliable structure. It can apply a certain downward pressure to the pressure plate 43, allowing the pressure plate 43 to stably press the material 6.
[0070] In this embodiment, see Figure 1 As a preferred design, the synchronous drive device 3 includes a synchronous power cylinder 31 fixedly mounted on the fixed frame 5. The synchronous power cylinder 31 can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The piston rod of the synchronous power cylinder 31 is along the X direction and is fixedly connected to the cutting frame 24. Multiple synchronous power cylinders 31 can be configured to move synchronously. The extension and retraction of the piston rods of the synchronous power cylinders 31 is controlled by the control system, driving the cutting device 2 to move linearly in the X direction. The structure is simple, stable, and reliable.
[0071] In this embodiment, see Figure 6 As a preferred design, the position detection device 7 includes a detection light receiver 72, which is disposed opposite to the detection light generator 71 on both sides of the first conveyor 11. The detection light receiver 72 can receive the detection light emitted by the detection light generator 71. Material 6 on the first conveyor 11 can enter between the detection light receiver 72 and the detection light generator 71, blocking the detection light. When this blocks the detection light, the detection light receiver 72 no longer receives the signal and thus emits a corresponding signal. In other embodiments, the position detection device 7 can also employ a reflective photoelectric detection principle, where the detection light emitted by the detection light generator 71 is reflected by a relatively disposed reflector before being received.
[0072] In this embodiment, see Figure 3 As a preferred design, both the first conveyor 11 and the second conveyor 12 of the conveying device 1 use conveyor belts for conveying. The conveyor belts are driven by motors and rollers to move and transport materials, which can effectively control the conveying speed of the first conveyor 11 and the second conveyor 12 and stably transport the material 6. In other embodiments, the first conveyor 11 and the second conveyor can also be conveyor roller conveyors composed of multiple conveyor rollers.
[0073] The present invention also provides a follow-up slicing method, which uses the above-mentioned follow-up slicer and includes the following steps:
[0074] S1. When the cutting device 2 is in the initial state, the cutter 21 is located on the upper side of the second conveyor 12, and the pressure plate 43 of the floating pressure plate device 4 is also located on the upper side of the second conveyor 12 initially. The first conveyor 11 and the second conveyor 12 convey at the same conveying speed. The material 6 to be sliced enters the second conveyor 12, and the second conveyor 12 conveys the material 6 on it to the first conveyor 11.
[0075] S2. When the front end of the material 6 to be sliced reaches the detection light emitted by the detection light generator 71 of the position detection device 7, the position detection device 7 sends a signal to the control system as a slicing working signal.
[0076] S3, Slicing:
[0077] S31. Cutting Action: After receiving the signal to start the cutting action, the control system controls the synchronous drive device 3 to move, driving the cutting device 2 to move in the same direction and at the same speed as the material 6 along the X direction. At the same time, the cutting device 2 drives the floating pressure plate device 4 to move synchronously. The control system also controls the cutting drive mechanism of the cutting device 2 to move, driving the cutter 21 to move downward in a straight line towards the second conveyor 12. The cutter 21 preferably moves downward at a uniform speed, cutting the material 6. The control system also controls the lifting mechanism of the floating pressure plate device 4 to move, driving the pressure plate 43 to move down and press on the material 6. When the cutter 21 moves to the cutting table 13, the cutter 21 just passes through the material 6 to be sliced and inserts into the cutting table 13, cutting the material 6 to be sliced. The material 6 slices obtained on the front side of the cutter 21 are output from the first conveyor 11 and finally sent to the next process. The material 6 portion on the rear side of the cutter 21 is reformed into the material 6 to be sliced, and the pressure plate 43 remains pressed on the material 6 to be sliced.
[0078] S32, Reset Action: The cutting device 2 first moves in the same direction and at the same speed as the material 6. At this time, the floating pressure plate device 4 also moves forward synchronously. The cutting drive mechanism drives the cutter 21 to move upward and retracts the cutter 21. Preferably, when the cutter 21 leaves the material 6, the lifting mechanism of the floating pressure plate device 4 drives the pressure plate 43 to move upward and leave the material 6. Then, the control system controls the synchronous drive device 3 to reverse the action and drive the cutting device 2 to move along the X direction toward the side where the second conveyor 12 is located. The cutting device 2 returns to the initial state, and the floating pressure plate device 4 also returns to the initial state. At this time, the front end of the material 6 to be sliced has not been reached.
[0079] S4. Repeat steps S2 to S3 to continuously slice the material into pieces.
[0080] As described above, the follow-up slicer and slicing method of the present invention have the following beneficial effects:
[0081] 1. By setting up a synchronous drive device 3, a position detection device 7, a first conveyor 11, a second conveyor 12, and a cutting platform 13, the position detection device 7 detects the position of the material 6 and uses it as a signal to start slicing. The control system automatically controls the synchronous drive device 3 to drive the cutting device 2 to move at the same speed and in the same direction as the material 6, so that the cutter 21 moves synchronously with the material 6 while cutting downwards. Slicing can be completed during the material 6 conveying and moving. At the same time, the remaining part of the slice can be automatically detected and sliced again, thereby realizing continuous automatic slicing, effectively improving work efficiency. It can be applied to the cutting of tobacco blocks, reducing tobacco fragmentation and improving the overall processing quality.
[0082] 2. By setting up a floating pressure plate device 4, which moves synchronously with the cutting device 2, and cooperates with the slicing work of the cutter 21, the device presses down the material 6 slices in front of the cutter 21 during the cutting process, ensuring the stability of the material 6 during the cutting process, reducing the breakage of tobacco sheets, and improving the overall processing quality.
[0083] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
[0084] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
