DETAILED DESCRIPTION

[0024] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0025] In a first aspect, the present invention provides an insulating paperboard cross-cutting edge processing device, such as Figures 1 to 7 As shown, it mainly includes a first conveying part 10, a second conveying part 20, a first cross-cutting unit 30, a second cross-cutting unit 40, an upstream flap 50, a downstream flap 60 and a first driving device 80.

[0026] Specifically, if Figure 1 As shown, the first conveying portion 10 and the second conveying portion 20 are used to convey the vehicle along a predetermined conveying path, for example Figure 1 In this embodiment, the first conveying part 10 and the second conveying part 20 can be independent conveying mesh belts or roller groups, such as Figure 1 and Figure 2 As shown, there is a preset gap between the first conveying portion 10 and the second conveying portion 20 , and the gap forms a first cutting seam 31 for cooperating with the first cross-cutting unit 30 to perform cutting.

[0027] Reference Figure 1 、 Figure 2 As shown, the first cross-cutting unit 30 is disposed downstream of the first conveying section 10. Its cutting tool, such as a cutter disc, can extend into the first slit 31 during operation to perform a transverse cut on the embryonic paper conveyed thereto. The second cross-cutting unit 40 is disposed downstream of the second conveying section 20. Its structure and function are similar to those of the first cross-cutting unit 30, and it is used to perform another transverse cut on the embryonic paper.

[0028] Reference Figure 1 、 Figure 3 The upstream flap 50 and the downstream flap 60 are positioned downstream of the second conveyor 20, i.e., below the working area of ​​the second cross-cutting unit 40. In this embodiment, both the upstream flap 50 and the downstream flap 60 are plate-like structures, capable of switching between a horizontal position and an inclined position. When both are in the horizontal position, their surfaces together form a flat support platform, supporting the embryonic paper flowing through the second conveyor 20. Simultaneously, a gap is formed between the upstream flap 50 and the downstream flap 60, which serves as the second slit 70 for facilitating cutting by the second cross-cutting unit 40.

[0029] The first driving device 80 is in transmission connection with both the upstream flap 50 and the downstream flap 60. As a specific embodiment, Figure 7 As shown, the transmission connection. As a specific embodiment, as Figure 7 As shown, the first drive device 80 may include two independent cylinders, which are hingedly connected to the bottom of the upstream flap 50 and the downstream flap 60 via respective connecting rod mechanisms, thereby independently controlling the flipping movement of each flap. In this embodiment, the first drive device 80 can be controlled by a control system such as a PLC (not shown) and is configured to execute the following two core drive modes: independent drive mode and linked drive mode.

[0030] In the independent driving mode, the control system can independently drive the upstream flap 50 or the downstream flap 60 to flip. In the linkage driving mode, the control system can simultaneously drive the upstream flap 50 and the downstream flap 60 to switch synchronously from the horizontal position to the inclined position.

[0031] Specifically, the paper embryo has a first thickness and a second thickness, the first thickness is smaller than the width of the second slit 70 , and the second thickness is larger than the width of the second slit 70 .

[0032] When processing the paper blank of the first thickness, the paper blank is relatively light and thin, and the control system will adopt an independent drive mode: the first drive device 80 independently drives the downstream flap 60 to switch to an inclined position to discharge the paper head waste, and independently drives the upstream flap 50 to switch to an inclined position to discharge the paper tail waste.

[0033] When processing the second thickness of embryonic paper, which is relatively thick and heavy, the control system switches to a linked drive mode for tail paper discharge: the first drive device 80 independently drives the downstream flap 60 to a tilted position to discharge the head waste, while simultaneously driving the upstream flap 50 and downstream flap 60 to tilted positions to discharge the tail waste. This avoids turning only the upstream flap 50, which could cause the tail waste to rest on the downstream flap 60, thereby ensuring reliable and smooth discharge of the thick and heavy tail waste.

[0034] In a second aspect, the present invention also provides a method for cross-cutting and edge processing of insulating paperboard, which is applied to the above-mentioned device, and its working process is as follows: S1: Convey the embryonic paper to the downstream flap 60 and stop. The control system activates the first conveying unit 10 and the second conveying unit 20 to convey the continuous embryonic paper to the predetermined cutting position. This position may be the position where the front end of the embryonic paper passes the second slit 70 for a distance and rests on the surface of the downstream flap 60. Then, the first conveying unit 10 and the second conveying unit 20 stop.

[0035] S2: The first and second cross-cutting units 30 and 40 are activated to cut the embryonic paper transversely along the first and second slits 31 and 70, separating the paper waste. After the first and second conveyor sections 10 and 20 stop, the control system simultaneously initiates commands to activate the first and second cross-cutting units 30 and 40, driving their respective cutting tools to move transversely, cutting the stationary embryonic paper transversely along the first and second slits 31 and 70, respectively. After these cuts, the leading end of the embryonic paper is separated as the paper waste, and the entire embryonic paper is cut into product segments of the target length.

[0036] S3: The downstream flap 60 is driven to tilt to an inclined position to discharge the waste paper. After cutting is completed, the first drive device 80 drives the downstream flap 60 from a horizontal position to an inclined position. The waste paper on it slides down to the waste collection area below due to gravity. The downstream flap 60 then returns to a horizontal position to prepare for the next process.

[0037] S4: The embryonic paper is continued to be conveyed to the upstream flap 50 and stops. The first conveying section 10 and the second conveying section 20 are started, and the cut embryonic paper product segment is continued to be conveyed forward until the product segment located upstream in the conveying direction, that is, the embryonic paper product segment located on the first conveying section 10 during the first cutting, is conveyed to the second conveying section 20, and the tail of the product segment reaches the plate surface of the upstream flap 50. The first conveying section 10 and the second conveying section 20 stop again.

[0038] S5: Start the second transverse cutting unit 40 to transversely cut the tail of the paper embryo along the second slit 70 to separate the paper tail waste.

[0039] S6: The flap action is selected based on the thickness of the paper blank. When the paper blank is thinner than the width of the second slit 70, the upstream flap 50 is driven alone to flip and discharge the waste paper. When the paper blank is thicker than the width of the second slit 70, both the upstream flap 50 and the downstream flap 60 are driven simultaneously to flip and discharge the waste paper. After completing these steps, the device enters the next operating cycle, thus achieving efficient and continuous automated production.

[0040] In some embodiments, as Figure 1 As shown, the first cross-cutting unit 30 and the second cross-cutting unit 40 can adopt the same structural design. The second cross-cutting unit 40 will be described below as an example.

[0041] The second cross-cutting unit 40 mainly includes a frame 41, a cutter seat 42, a cutter head 43 and a second driving device 44 for driving the cutter head 43 to move horizontally.

[0042] The frame 41 is the supporting skeleton of the entire cross-cutting unit. In this embodiment, the frame 41 includes L-shaped columns 411 on both sides and crossbeams 412 connecting the columns, forming a gantry structure, which provides a basic platform for the installation and stable operation of other components.

[0043] The cutter seat 42 is slidably mounted on the frame 41, and the second drive device 44 drives the cutter seat 42 to move horizontally, perpendicular to the conveying direction. Specifically, a linear track 413 is provided on the crossbeam 412. The cutter seat 42 slides on this linear track 413 and moves along this track under the drive of the second drive device 44. The second drive device 44 precisely controls the movement speed, start and stop positions, and number of round trips of the cutter seat 42 through commands from the control system.

[0044] The cutter head 43, mounted on the cutter seat 42, is the component that directly performs the cutting task. Vertically, the cutter head 43 of the first cross-cutting unit 30 at least partially extends into the first slit 31, and the cutter head 43 of the second cross-cutting unit 40 at least partially extends into the second slit 70. This arrangement ensures that the cutter head 43 can completely cut through the embryonic paper during the cutting process without interfering with the conveying unit or flap below, resulting in a good cutting effect.

[0045] In some embodiments, as Figure 5 、 Figure 6As shown, the cutter base 42 is equipped with a motor 45 that drives the cutter head 43, a cylinder 46, a vertically extending slide rail 47, and a slider 48 that slides with the slide rail 47. The cutter head 43 is detachably mounted on the slider 48. The piston rod of the cylinder 46 is connected to the slider 48 to drive the slider 48 to move vertically along the slide rail 47. When not cutting, the cutter head 43 can be raised to a safe position to avoid accidental contact with the paper blank. When cutting is required, the cutter head 43 can be precisely lowered to a preset working height to ensure the cutting depth, adapting to paper blanks of varying thicknesses and meeting different process requirements.

[0046] When implementing it specifically, Figure 6 As shown, the cutter head 43 is a cutter disc, which is coaxially fixedly connected to a first bevel gear 431 , and the output shaft of the motor 45 is coaxially fixedly connected to a second bevel gear 451 meshing with the first bevel gear 431 .

[0047] In some embodiments, the second cross-cutting unit 40 further includes a cleaning brush (not shown) that is slidably connected to the crossbeam 412 and contacts the surfaces of the upstream flap 50 and the downstream flap 60. During operation, after the upstream flap 50 and the downstream flap 60 are reset, the cleaning brush cleans paper scraps from the upper surfaces of the upstream flap 50 and the downstream flap 60. As a feasible implementation, the cleaning brush 90 is connected to the crossbeam 412 of the frame 41 via a sliding bracket that can slidably engage with an independent guide rail provided on the crossbeam 412 and is driven by, for example, a stepper motor in conjunction with a lead screw or a synchronous belt. When the cutting and waste discharge processes are completed and the upstream flap 50 and the downstream flap 60 are reset to the horizontal position, the control system will start the motor driving the cleaning brush 90, causing it to perform one or more reciprocating motions on the beam 412. During this process, the cleaning brush 90 sweeps across the entire surface of the upstream flap 50 and the downstream flap 60, sweeping off attached paper scraps and other debris to prevent the residual paper scraps from causing unexpected damage to the paper blank.

[0048] In some embodiments, as Figure 4As shown, the second driving device 44 specifically includes: a driving wheel 441, a driven wheel 442, a synchronous belt 443, a chuck 444, and a driving motor 445. The driving wheel 441 and the driven wheel 442 are respectively arranged at both ends of the crossbeam 412, with their rotation axes parallel to each other and perpendicular to the length direction of the crossbeam 412; the synchronous belt 443 is wound around the driving wheel 441 and the driven wheel 442, with its straight section perpendicular to the conveying direction; the chuck 444 is a connecting member, one end of which is firmly fixed to the outer surface of the synchronous belt 443, and the other end is rigidly connected to the cutter seat 42, so that the movement of the cutter seat 42 is completely coupled to the linear motion of the synchronous belt 443; the driving motor 445 is a power source, and its output shaft is connected to the driving wheel 441 through a coupling or a reducer.

[0049] The operating principle of the second drive unit 44 is as follows: When the control system issues a command to the drive motor 445, the drive motor 445 rotates, and its power is transmitted to the driving wheel 441 via the output shaft, causing the driving wheel 441 to rotate. This rotation of the driving wheel 441 in turn drives the timing belt 443 in a circular motion. Because the chuck 444 is fixed to the timing belt 443, the circular motion of the timing belt 443 is converted into linear reciprocating motion of the chuck 444 and the cutter seat 42 connected to it. By controlling the number of rotations and direction of the drive motor 445, the distance, speed, and position of the cutter seat 42 on the crossbeam 412 can be precisely controlled, thereby completing the transverse cutting stroke of the first and second cross-cutting units 30 and 40.

[0050] The insulating cardboard cross-cut edge processing device and processing method provided in the embodiment of the present application, by setting up two synchronously acting cross-cutting units, can complete paper head separation and product segment cutting with a single stop of the conveying mechanism, shortening the production cycle of a single cardboard and improving production efficiency; at the same time, using two independently or linked controllable flaps, the paper head and paper tail waste are discharged in a time-sharing manner, ensuring the continuity of the production process and avoiding platform contamination; in addition, the device can adaptively select the waste discharge action according to the thickness of the cardboard, improving the versatility and operational stability for products of different specifications.
