Abstract
Description
Technical Field
[0001] This invention relates to the field of food packaging machinery, and more particularly to a strip-shaped packaging production line. Background Technology
[0002] In existing strip packaging production lines, the strips can be sheet-like, and their cross-sections can be circular, elliptical, or other shapes. The cutting device is usually independently set up, with continuous material directly entering the cutting device to be cut into segments. These segments are then conveyed to the subsequent packaging device via a conveyor. The current specific process flow is as follows: the segments cut by the cutting device are conveyed at equal intervals via a conveyor belt, and then pushed synchronously by pushers into the material trough of the packaging device's feeding mechanism for packaging. Current cutting devices only have a single up-and-down cutting function, and this existing technology has several problems: 1. For sticky strips, such as candy bars, the cut pieces tend to stick together at the cut point after the cutter finishes cutting the continuous material. This often requires an additional pushing device to separate them downstream. 2. Due to the inherent adhesiveness of candy, the cutter blade easily adheres to the material after cutting. If not cleaned promptly, this directly affects the quality of subsequent cuts. 3. Existing production lines have cutting and packaging devices positioned too far apart, suitable only for flat, continuous strips. They cannot handle round or irregularly shaped strips, affecting the consistency of finished product specifications and the yield rate of the packaging unit. 4. Existing packaging units use a chain hook conveyor system, which is complex, has too many cleaning dead zones, and requires too many replacement parts for product specification changes, making debugging difficult. 5. Continuous strips are prone to lateral shifting during forward conveying, leading to inaccurate cutting positions and misalignment with subsequent packaging, affecting the consistency of finished product specifications and causing defective products. In the process of removing defective products, existing rejection mechanisms are often complex in structure and occupy a large space, which increases the difficulty of the layout of the entire production line. Summary of the Invention
[0003] This invention addresses the shortcomings of existing technologies by providing a strip-shaped material packaging production line to solve the technical problems of easy adhesion at the cut end of strip-shaped materials, easy adhesion of materials to the blade surface, and limited applicability to a single material specification and type.
[0004] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention, by adopting the above technical solutions, has significant technical effects: A strip-shaped material packaging production line includes a first conveying device, a cutting device, and a subsequent packaging device. The first conveying device is used to convey several continuous strip-shaped materials side by side along a first conveying direction. The cutting device cuts the continuous strip-shaped materials located on the first conveying device and outputs segmented materials. The cutting device includes a cutting frame and a cutter. The cutting blade extends perpendicular to the first conveying direction. The cutter is connected to a cutter power source through a lifting transmission assembly. The cutter power source drives the cutter to move up and down, so that the movement path of the cutter has a lowest point and a highest point. The subsequent packaging device is used to package the segmented materials output by the cutting device. The cutter is connected to a lateral movement power source via a lateral transmission assembly. This lateral movement power source and the cutter's power source may be the same or different. When the cutter passes its lowest point, the lateral movement power source drives the cutter to move in the first conveying direction, pushing the material segments downstream and separating them at the cut point. When the cutter reaches its highest point, its horizontal position resets. By setting the lateral movement power source to drive the cutter to move in the first conveying direction after cutting, the cutter simultaneously pushes the material segments downstream and separates them at the cut point, preventing material segments from sticking together. The horizontal position resets when the cutter reaches its highest point, thus integrating the cutting and material separation functions into the same cutter movement trajectory, simplifying the structure of the cutting device.
[0005] Preferably, the power source for the cutter is connected to a rotating shaft with both ends mounted on the cutting machine frame. The lifting transmission assembly includes a lifting drive wheel and a lifting connector. One end of the lifting connector is movably connected to the cutter, and the other end is connected to the lifting drive wheel. The lifting connector and the lifting drive wheel are either eccentrically connected, or the lifting drive wheel is a cam. By eccentrically connecting the lifting connector to the lifting drive wheel or setting the lifting drive wheel as a cam, the rotational motion is reliably converted into the lifting motion of the cutter, so that the rotating shaft completes one cycle after each revolution. The motion trajectory is stable, and the transmission structure is simple.
[0006] Preferably, the lateral movement transmission assembly includes a lateral movement mounting base that can move back and forth relative to the cutting frame, a follower slider, and a vertical guide bar. The vertical guide bar is fixedly connected to the lateral movement mounting base, and the follower slider is slidably connected to the vertical guide bar. The lateral movement mounting base is connected to a lateral movement power source, and the follower slider is fixedly connected to the cutter. The lateral movement power source drives the lateral movement mounting base, which in turn drives the follower slider, to move the cutter horizontally. The cutter power source drives the cutter to move up and down, causing the follower slider to move up and down along the vertical guide bar. Through the fixed installation of the vertical guide bar and the lateral movement mounting base, and the sliding engagement of the follower slider and the vertical guide bar, the cutter gains horizontal lateral movement freedom while the vertical guide bar provides guidance for the cutter's up and down movement, ensuring the accuracy and stability of the combined up and down movement of the cutter.
[0007] Preferably, the lateral movement power source and the cutting blade power source are the same power source. The lateral movement transmission assembly includes a lateral movement drive wheel and a lateral movement connector. One end of the lateral movement connector is movably connected to the lateral movement mounting base, and the other end of the lateral movement connector is connected to the lateral movement drive wheel. The lateral movement connector and the lateral movement drive wheel are either eccentrically connected, or the lateral movement drive wheel is a cam. By setting the lateral movement power source and the cutting blade power source to the same power source, and achieving lateral movement through the eccentric connection or cam transmission between the lateral movement connector and the lateral movement drive wheel, the number of power sources is reduced, making the cutting device more compact, improving synchronization, facilitating control, and reducing equipment costs.
[0008] Preferably, both the lifting drive wheel and the lateral drive wheel are cams. The projection of the central axis of the lifting connector and the central axis of the lateral drive connector onto the vertical plane forms a 90° angle. When the lifting connector drives the cutter to its lowest point and rises, the lateral drive connector drives the lateral mounting base to move the cutter horizontally downstream of the production line. When the lifting connector drives the cutter to its lowest point, the lateral drive connector is at its farthest position from the cutter. When the cutter rises, the lateral drive connector drives the lateral mounting base to move inward horizontally. By setting both the lifting drive wheel and the lateral drive wheel as cams, and ensuring that the projection of the central axis of the lifting connector and the central axis of the lateral drive connector onto the vertical plane forms a 90° angle, the phase relationship between the two connectors is defined: when the cutter reaches its lowest point, the lateral drive connector is at its farthest position from the cutter; when the cutter rises, the lateral drive connector drives the lateral mounting base to move inward. This achieves precise phase coordination between the lifting cutting and the lateral pushing, ensuring that the cutter completes the pushing and resetting actions at the appropriate time.
[0009] Preferably, the lifting connector includes a sleeve, a screw, an adjusting nut, and a locking nut. The top of the screw is connected to the lifting drive wheel, and the bottom of the sleeve is rotatably connected to the cutter. The bottom end of the screw extends into a through hole at the top of the sleeve. The adjusting nut is located above the locking nut, and the locking nut is threadedly engaged with the screw. The adjusting nut is fixed to the screw or threadedly engaged with it. Rotation changes the screw's insertion depth relative to the sleeve, and the locking nut contacts the sleeve, locking the screw's position. The thread can be a single-stage thread, locked by the locking nut after rotation. The screw can also have two stages of threads with different directions and pitches, using the principle of differential threads for fine adjustment. The purpose is to allow for fine adjustment of the cutter's height on one side, ensuring that the bottom of the cutter is completely parallel to the conveying plane, thereby improving the cutting effect.
[0010] Preferably, one end of the transverse connecting member is movably connected to the transverse mounting base and is connected to a first connecting rod. One end of the first connecting rod is hinged to the transverse connecting member, and the other end is hinged to the transverse mounting base via a second connecting rod. The central section of the first connecting rod is hinged to the cutting frame, causing the movement direction of the second connecting rod to be opposite to that of the transverse connecting member. By setting the first and second connecting rods between the transverse connecting member and the transverse mounting base, and hinged the central section of the first connecting rod to the cutting frame, the lever principle is used to make the movement direction of the second connecting rod opposite to that of the transverse connecting member. Thus, the change of movement direction is achieved with a simple linkage mechanism, which facilitates flexible adjustment of the installation position of the transverse mounting base according to the spatial layout of the cutting frame.
[0011] Preferably, the cutting device further includes an anti-sticking component, which is disposed on the downstream side and / or upstream side of the cutting path of the cutter. There is a space for material to pass through between the anti-sticking component and the supporting surface of the first conveying device. Each anti-sticking component is disposed opposite to one side of the cutter's blade surface. The anti-sticking component is fixedly connected to the transverse mounting base so that the horizontal relative position between the anti-sticking component and the cutter remains unchanged. When the cutter completes a single cutting action at the lowest point and moves towards the highest point, it moves upward relative to the anti-sticking component. During the upward movement of the cutter, the anti-sticking component holds back the material adhering to the blade surface of the cutter, causing the adhered material to detach from the blade surface. By fixing the anti-sticking component to the transverse mounting base, the horizontal relative position between the anti-sticking component and the cutter remains unchanged. During the process of the cutter moving to the highest point after completing the cut, the cutter moves upward relative to the anti-sticking component, and the anti-sticking component sweeps across the cutter surface or at close range, thereby effectively preventing material from adhering to the cutter surface, or allowing the material that has already adhered to the cutter surface to detach from the cutter surface in time. Since the anti-sticking component is linked with the transverse mounting base, there is no need to configure a separate drive mechanism, and the relative motion is generated by the movement of the cutter.
[0012] Preferably, the cutting device further includes an anti-sticking member disposed downstream and / or upstream of the cutting path of the cutter. Each anti-sticking member is disposed opposite to one side of the cutter's blade surface. After the cutter completes a single cutting action at its lowest point, the anti-sticking member has a downward relative displacement relative to the cutter, at least in the vertical direction, causing it to sweep across the cutter's blade surface or at a distance no greater than the thickness of the material adhesion layer, thus detaching the adhered material from the blade surface. By providing an anti-sticking member that has a downward relative displacement relative to the cutter, at least in the vertical direction, after the cutter completes the cutting, allowing it to sweep across or closely pass over the blade surface, another anti-sticking implementation method is provided. This method effectively prevents material adhesion or promotes the detachment of already adhered material, and has a simple structure.
[0013] Preferably, the first conveying device includes a first conveyor belt; the first conveyor belt is equipped with a guiding mechanism for lateral limiting and guiding the continuous material. Since the material needs to travel a relatively long conveying path, such as undergoing cold treatment or powdering, multiple guiding mechanisms can be set along the conveying path to prevent lateral deviation of the material during conveying, thereby ensuring that the cutting device can accurately position and cut the material. Using a conveyor belt ensures that the material is laid flat and conveyed using friction during transfer or transport, solving the problems of difficult adjustment of the chain hook distance and easy snagging of material on the chain hooks in traditional chain conveyors.
[0014] Preferably, the guiding mechanism includes a guide roller located above the first conveyor belt. The guide roller has several limiting wheels arranged axially or integrally formed, with an annular groove formed between adjacent limiting wheels. Continuous strip-shaped material is placed within this annular groove, and the sidewalls of the limiting wheels guide and limit the sides of the strip-shaped material, ensuring it travels along the extension direction of the annular groove during conveying. The guide roller is configured to rotate around its axis or remain stationary. By configuring the guiding mechanism as a guide roller with several limiting wheels, the annular groove formed between adjacent limiting wheels accommodates the continuous strip-shaped material, and the sidewalls of the limiting wheels guide and limit the material on both sides, ensuring stable travel along the extension direction of the annular groove. Compared to traditional spaced guide plates, the guide roller prevents material jamming because guide plates need to be positioned above the conveyor belt and have a certain distance from it. Therefore, strip-shaped material easily enters the gap between the guide plate and the conveyor belt during the guiding process. The guide roller's method of lifting the material provides stable and jam-free guidance for continuously conveyed materials.
[0015] Preferably, the conveying speed of the conveying device connected to the downstream of the first conveying device is faster than that of the first conveying device, so that the material conveying speed at the end of the first conveying device is faster than the material below the cutter. This achieves a certain distance between the segments of material, facilitating subsequent packaging.
[0016] Preferably, the downstream packaging device is equipped with a second conveying device, and a waste removal conveying mechanism is provided between the first conveying device and the second conveying device. The waste removal conveying mechanism is a telescopic conveyor belt extending from the second conveying device or the first conveying device, or the waste removal conveying mechanism removes materials by flipping up and down or moving horizontally. The waste removal conveying mechanism and the second conveying device have the same conveying speed, and the conveying speed is greater than that of the first conveying device, so as to create a distance difference between the cut materials through the difference in conveying speed.
[0017] This invention, by adopting the above technical solutions, has significant technical effects: The equipment utilizes a continuous conveying method for intermediate processes, and then sends the material to the cutting device for cutting before it directly enters the packaging process. This eliminates the need for pre-cutting and intermittent conveying, making the equipment more integrated with the production and packaging process. Furthermore, the continuous processing method without the need for transfer simplifies the conveying process, making it more convenient and resulting in a higher yield.
[0018] It integrates cutting and material separation functions. After the cutter completes the cutting, it uses its own displacement to directly push the cut material downstream, so that the materials do not stick together. No additional material feeding mechanism is needed, which simplifies the equipment structure, reduces production costs, and greatly saves the space required for the production line. The anti-stick component effectively prevents materials from adhering to the cutter, ensuring cutting accuracy and material integrity, and resulting in a higher yield rate for the equipment.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Example
[0022] A strip-shaped packaging production line, such as Figure 1 As shown, the assembly line includes a first conveying device 2, a cutting device 1, and a subsequent packaging device 3. The first conveying device 2 is used to convey several continuous strip-shaped materials side-by-side along a first conveying direction. The strip-shaped materials on the first conveying device 2 are continuous, and the conveyed materials can be directly output from equipment that manufactures materials, such as sugar-making equipment, or output after longitudinal cutting, or output in roll form. The cutting device 1 is correspondingly located at the end of the first conveying device 2, and cuts the continuous strip-shaped materials conveyed on the first conveying device 2 before still being sent out through the first conveying device 2. If the first conveying device 2 has a preceding processing step, it needs to be composed of multiple conveyor belt segments connected together until it reaches the cutting device 1. However, if it is sent directly to the cutting device 1 without processing, then the first conveying device 2 can also be a single conveyor belt segment. The assembly line can be a single line or a series of other lines. Figure 2 As shown, multiple production lines are arranged in parallel. A continuous strip of material is diverted and distributed to the first conveyor device 2 of each production line for subsequent processing. The cutting device 1 cuts the continuous strip of material on the first conveyor device 2 and outputs segmented material. The cutting device 1 includes a cutting frame 11 and a cutter 12. The blade of the cutter 12 extends perpendicular to the first conveying direction. The cutter 12 is connected to a cutter power source 51 through a lifting transmission assembly. The cutter power source 51 drives the cutter 12 to move up and down, so that the movement path of the cutter 12 has a lowest point and a highest point. The subsequent packaging device 3 is used to package the segmented material output by the cutting device 1. like Figure 4-8As shown, the cutter 12 is also connected to a lateral movement power source 41 via a lateral movement transmission assembly. The lateral movement power source 41 and the cutter power source 51 may be the same power source or different power sources. When the cutter 12 passes the lowest point, the lateral movement power source 41 drives the cutter 12 to move in the first conveying direction, pushing the segmented material downstream and separating the material at the cut point. When the cutter 12 reaches the highest point, the cutter 12 resets its position in the horizontal direction. The lateral movement transmission assembly is connected to the cutter in a fixed or movable manner. The lateral movement transmission assembly and the lifting transmission assembly may include, but are not limited to, slider guide rails, connecting rods or connecting rod groups, cam connecting rods, lead screws and nuts, and gear racks. The lateral movement power source and the cutter power source 51 may be motors, cylinders, or other conventional power sources in the art. Their purpose is to realize the lifting and lateral movement of the cutter, and therefore they are not limited. The horizontal position reset of the cutter 12 can be achieved by the lateral movement force source 41 through cyclic or reciprocating motion of the lateral transmission component, or by the cutter being connected to the cutting frame 11 with a spring for limiting and resetting using the elasticity of the spring. The subsequent packaging device 3 can be one or more integrated units of packaging equipment commonly used in the art, such as four-side sealing packaging devices, packaging film packaging, and canning packaging machines. Since this is not the technical solution that this invention aims to protect, its specific type and mechanism are not limited here.
[0023] In one embodiment of the present invention, the power source 51 for the cutter and the lifting transmission assembly are implemented such that the power source 51 for the cutter is connected to a rotating shaft 13 with both ends mounted on the cutting frame 11. The lifting transmission assembly includes a lifting drive wheel 53 and a lifting connector 52. One end of the lifting connector 52 is movably connected to the cutter 12, and the other end of the lifting connector 52 is connected to the lifting drive wheel 53. The lifting connector 52 and the lifting drive wheel 53 are eccentrically connected, or the lifting drive wheel 53 is a cam. The purpose is to make the top of the lifting connector 52 eccentrically set relative to the rotating shaft 13, and to lift the bottom lifting connector 52 connected to the cutter end by rotating the rotating shaft 13.
[0024] like Figure 7-8 As shown, in one embodiment of the present invention, the transverse transmission assembly includes a transverse mounting base 42, a follower slider 43, and a vertical guide bar 44 that are movable back and forth relative to the cutting frame 11. The vertical guide bar 44 is fixedly connected to the transverse mounting base 42, and the follower slider 43 is slidably connected to the vertical guide bar 44. The transverse mounting base 42 is driven by a transverse power source 41, and the follower slider 43 is fixedly connected to the cutter 12. The transverse power source 41 drives the transverse mounting base 42 to move horizontally in conjunction with the follower slider 43, and the cutter 12 moves horizontally. The cutter power source 51 drives the cutter 12 to move up and down, causing the follower slider 43 to move up and down along the vertical guide bar 44. The vertical guide bar 44 can be a guide post passing through the follower slider 43 or it can be guided and engaged with the follower slider 43 in a sliding rail manner.
[0025] like Figure 5-6 As shown, further, as one possible synchronous linkage method, the lateral movement power source 41 and the cutter power source 51 are the same power source. The lateral movement transmission assembly includes a lateral movement drive wheel 45 and a lateral movement connector 46. One end of the lateral movement connector 46 is movably connected to the lateral movement mounting base 42, and the other end of the lateral movement connector 46 is connected to the lateral movement drive wheel 45. The lateral movement connector 46 and the lateral movement drive wheel 45 are eccentrically connected, or the lateral movement drive wheel 45 is a cam. As shown in the figure, both the lifting drive wheel 53 and the transverse drive wheel 45 are cams. The lifting connector 52 and the transverse connector 46 are fixedly connected to the lifting drive wheel 53 and the transverse drive wheel 45 respectively or are integrally formed. The projection of the central axis of the lifting connector 52 and the central axis of the transverse connector 46 on the vertical plane is 90°. When the lifting connector 52 drives the cutter 12 to reach the lowest point and rises, the transverse connector 46 drives the transverse mounting base 42 to move the cutter 12 in the horizontal direction downstream of the production line. When the lifting connector 52 drives the cutter 12 to reach the lowest point, the transverse connector 46 is at the position farthest from the cutter 12. When the cutter 12 rises, the transverse connector 46 drives the transverse mounting base 42 to move inward in the horizontal direction.
[0026] like Figure 7 As shown, as an optional further embodiment, a connecting rod 47 is connected to one end of the transverse connecting member 46 and the transverse mounting base 42. One end of the connecting rod 47 is hinged to the transverse connecting member 46, and the other end is hinged to the transverse mounting base 42 via a connecting rod 48. The central section of the connecting rod 47 is hinged to the cutting frame 11 so that the movement direction of the connecting rod 48 is opposite to that of the transverse connecting member 46.
[0027] like Figure 8 As shown, the lifting connector 52 includes a sleeve 521, a screw 522, an adjusting nut 523, and a locking nut 524. The top end of the screw 522 is connected to the lifting drive wheel 53, and the bottom end of the sleeve 521 is rotatably connected to the cutter 12. The bottom end of the screw 522 extends into the through hole at the top end of the sleeve 521. The adjusting nut 523 is located above the locking nut 524, and the locking nut 524 is threadedly engaged with the screw 522. The adjusting nut 523 is fixed to the screw 522 or threadedly engaged with it. Rotation changes the screw 522's screw depth relative to the sleeve 521. The locking nut 524 contacts the sleeve 521 and locks the position of the screw 522. The screw can be a single-segment thread, which is locked by the locking nut 524 after rotation. The screw 522 can also have two segments of threads with different directions and pitches, allowing for fine-tuning using differential threads.
[0028] In one embodiment of the present invention, the lateral movement power source 41 and the cutter power source 51 are the same power source. The cutting device 1 also includes the anti-adhesion component 6, which works in conjunction with this power source. The anti-adhesion component 6 is located downstream and / or upstream of the cutting path of the cutter 12. There is a space for material to pass through between the anti-adhesion component 6 and the supporting surface of the first conveying device 2. Each anti-adhesion component 6 is positioned opposite to one side of the cutter 12. The anti-adhesion component 6 is fixedly connected to the lateral movement mounting base 42, so that the horizontal relative position between the anti-adhesion component 6 and the cutter 12 remains unchanged. When the cutter 12 moves from the lowest point to the highest point after completing a single cutting action, it moves upward relative to the anti-adhesion component 6. During the upward movement of the cutter 12, the anti-adhesion component 6 holds back the material adhering to the cutter surface of the cutter 12, causing the adhered material to detach from the cutter surface.
[0029] In another embodiment of the present invention, the anti-adhesion member 6 is provided with an independent additional power source, or the anti-adhesion member 6 is not connected to any power source but achieves its desired effect by utilizing the displacement of the cutter. The cutting device 1 also includes the anti-adhesion member 6, which is disposed downstream and / or upstream of the cutting path of the cutter 12. Each anti-adhesion member 6 is disposed opposite to one side of the blade surface of the cutter 12. After the cutter 12 completes a single cutting action at the lowest point, the anti-adhesion member 6 has a downward relative displacement relative to the cutter 12 at least in the vertical direction, so that the anti-adhesion member 6 sweeps across the blade surface of the cutter 12 or at a distance from the blade surface not greater than the thickness of the material adhesion layer, and the material used for adhesion is removed from the blade surface.
[0030] like Figure 1-3 As shown, in one embodiment, the first conveying device 2 includes a first conveyor belt; a guide mechanism 21 is provided on the first conveyor belt for lateral limiting and guiding continuous material. The guide mechanism can be vertically spaced guide plates, but such guide plates need to be positioned above the conveyor belt and at a certain distance from the conveyor belt. The guide mechanism 21 can also include a guide roller, which is located above the first conveyor belt. The guide roller is arranged along the axial direction or integrally formed with several limiting wheels 212. An annular groove 211 is formed between adjacent limiting wheels 212. The continuous strip-shaped material is placed in the annular groove 211. The sidewalls of the limiting wheels 212 limit and guide the side of the strip-shaped material, so that the strip-shaped material keeps moving along the extension direction of the annular groove 211 during the conveying process; the guide roller is configured to rotate about its axis or remain stationary.
[0031] The conveying speed of the conveying device connected to the downstream of the first conveying device 2 is faster than that of the first conveying device 2, so that the material conveying speed at the end of the first conveying device 2 is faster than that of the material below the cutter 12. This achieves a certain distance between the segments of material, facilitating subsequent packaging. As one embodiment, the downstream packaging device 3 is provided with a second conveying device 31, and a waste removal conveying mechanism 7 is provided between the first conveying device 2 and the second conveying device 31. The waste removal conveying mechanism 7 is a telescopic conveyor belt extending from the second conveying device 31 or the first conveying device 2, or the waste removal conveying mechanism 7 removes material by flipping up and down or moving horizontally. The conveying speeds of the waste removal conveying mechanism 7 and the second conveying device 31 are the same, and this conveying speed is greater than that of the first conveying device 2, so as to create a distance difference between the segments of material through the difference in conveying speed. The telescopic conveyor belt can have two platforms for installing the conveyor belt. The two platforms can extend and retract relative to each other, so that one conveyor belt is hidden under the other, thus leaving the area under the conveyor path empty. The telescopic conveyor belt or the waste removal conveyor mechanism 7 is a conventional setting in the field and will not be described in detail here.
[0032] One working principle of a single power source: The lateral movement power source 41 and the cutting blade power source 51 are the same power source, which can be a servo motor.
[0033] The first conveying device 2 is a first conveyor belt with guide rollers on top. The guide rollers are integrally formed with several limiting wheels 212. An annular groove 211 is formed between adjacent limiting wheels. Continuous strip-shaped materials are placed in the annular grooves. The side walls of the limiting wheels limit the material to the left and right. The lower surface of the continuous strip-shaped materials is attached to the first conveyor belt and flips upward over the guide rollers when passing through multiple guide rollers. If there are other guiding mechanisms such as guide plates, the materials can also be limited to the left and right until the materials reach the cutting position of the cutting device 1.
[0034] The cutting blade power source 51 is connected to the rotating shaft 13 at both ends of the cutting machine frame 11. The lifting drive wheel 53 and the transverse drive wheel 45 are both cams, which are fixedly installed on the rotating shaft 13. One end of the lifting connector 52 is hinged to the cutter 12, and the other end is eccentrically connected to the lifting drive wheel 53; one end of the transverse connector 46 is hinged to the transverse mounting base 42 through connecting rod 1 47 and connecting rod 2 48, the central section of connecting rod 1 47 is hinged to the cutting frame 11, and the other end is eccentrically connected to the transverse drive wheel 45. The power source drives the rotating shaft 13 to rotate. The central axis of the lifting connector 52 and the horizontal moving connector 46 are projected at 90° in the vertical plane. When the rotating shaft 13 rotates to the point where the cutter 12 reaches the lowest point, a single cut is completed. The lifting connector 52 drives the cutter 12 to rise, and at the same time, the horizontal moving connector 46 reaches the point furthest from the rotating shaft 13 in the horizontal direction. Through the linkage, the horizontal moving mounting base 42 moves downstream of the production line, so that the cutter 12 moves obliquely upward in this section of the path, pushing the segmented material to separate from the continuous material upstream. When the rotating shaft 13 rotates 90° again, and the cutter 12 rises but does not reach the highest point, the horizontal moving connector 46 moves inward again, causing the horizontal moving mounting base 42 to drive the cutter 12 to reset its horizontal position. In the horizontal direction, the reset position is consistent with the cutting position of the cutter 12 at the lowest point.
[0035] The anti-stick component 6 is a scraper, which is fixedly installed on the horizontal moving mounting base 42. Therefore, in the horizontal direction, the horizontal moving mounting base 42, the follower slider 43, the vertical guide bar 44, the anti-stick component 6, and the cutter 12 all move synchronously without relative displacement.
[0036] As one implementation method of linkage, the cutting frame 11 has a lateral moving mounting base 42 that can move back and forth. In the figure, the cutting frame 11 has slots on both sides for the lateral moving mounting base 42 to move. The lateral moving mounting base 42 has a guide rod extending along the lateral direction. The lateral moving mounting base 42 moves relative to the cutting frame 11 by sliding the slider at the rear with the guide rod. The power source drives the rotating shaft 13, which in turn drives the lateral moving connecting piece 46 to swing. As a result, the connecting rod 1 47 and the connecting rod 2 48 move the lateral moving mounting base 42 laterally. The vertical guide bar 44 fixed on the lateral moving mounting base 42 and the follower slider 43 installed on the vertical guide bar 44 move laterally in sync, which drives the cutter 12 fixed to the follower slider 43 to move laterally. At the same time, due to the linkage of the lifting connecting piece 52, the cutter 12 is in a lifting motion. The cutter 12 drives the follower slider 43 to rise and fall along the vertical guide bar 44. This lifting and falling does not affect their respective displacements in the horizontal direction.
[0037] The anti-sticking component 6 is arranged opposite to the two sides of the blade of the cutter 12. Only one side of the anti-sticking component 6 is shown in the figure, and the other side is not shown. When the cutter 12 rises, it moves upward relative to the anti-sticking component 6. The anti-sticking component 6 sweeps across the blade and scrapes off the adhered material.
[0038] A waste rejection conveying mechanism 7 is provided between the second conveying device 31 and the first conveying device of the post-packaging device 3. It is a conveyor belt that can be flipped up and down. When unqualified materials are detected, the conveyor belt flips to reject the materials.
[0039] If the power source is an independently controlled structure, the working principle is different from the above in that the lateral movement power source 41 and the cutting power source 51 are different power sources. As one option, the cutting power source 51 can be a hydraulic cylinder, and the lateral movement power source 41 can be a pneumatic cylinder.
[0040] When the continuous material passes through the cutting device, the cutting device intermittently cuts the continuous material; the cutter 12 is connected to the cutter power source 51 through the lifting transmission assembly, and the cutter power source 51 drives the cutter to rise and fall to complete the cutting; the transverse mounting base 42 is connected to the transverse force source 41, and the transverse force source 41 drives the transverse mounting base 42 to move horizontally; the follower slider 43 is fixedly connected to the cutter and slides in cooperation with the vertical guide bar 44 on the transverse mounting base; After the cutter completes the cutting at the lowest point, the lateral power source 41 drives the lateral mounting base to move the cutter downstream of the production line, thus promoting material conveying; when the cutter reaches the highest point, the lateral power source 41 drives the lateral mounting base to reset.
[0041] The anti-sticking component 6 is located downstream of the cutting path of the cutter 12. When the cutter finishes cutting and rises, the anti-sticking component remains stationary, and the cutter 12 moves obliquely upward relative to the anti-sticking component 6. The anti-sticking component 6 sweeps across the blade surface and scrapes off the adhered material.
