Description

Technical Field

[0001] This utility model relates to the field of printing and packaging technology, and in particular to an ultrasonic paper edge trimming device. Background Technology

[0002] In the mass production process of paperboard in the printing and packaging industry, after the printed paperboard is made, it is often necessary to trim one side to ensure that all paperboards are dimensionally uniform in the width direction. This meets the dimensional accuracy requirements of subsequent processes such as carton forming and product packaging. This process is one of the key links to ensure the quality stability of printed and packaged products.

[0003] Currently, for the aforementioned demand for continuous single-sided trimming of large-volume, long-sized printed cardboard, existing technologies primarily employ roller cutters as the core processing equipment. Their working principle is as follows: utilizing the continuous rotation of a circular blade in conjunction with a matching anvil, the high-speed rotation of the blade generates shearing force to continuously cut one side of the long-sized printed cardboard during transport, thus achieving efficient trimming. Due to its high cutting speed and adaptability to continuous production processes for long-sized cardboard, this type of roller cutter is widely used in large-scale printed cardboard processing scenarios such as carton production lines, effectively supporting the mass production needs of the printing and packaging industry.

[0004] However, in actual production, different types of printed packaging products have different requirements for cardboard width. To meet the single-sided cutting requirements of cardboard of different widths, manufacturers need to equip their rotary cutters with various specifications of circular blades. When production orders switch to processing cardboard of different widths, workers need to stop the machine, disassemble the current specification of the circular blade, and replace it with a new specification that matches the target cardboard width. This process not only consumes a lot of downtime for blade replacement, seriously affecting the continuous operation efficiency of the production line and extending the production cycle, but also requires additional costs for the purchase, storage, and daily maintenance of multiple specifications of circular blades, increasing the burden on the company's production operations. In addition, frequent disassembly and installation of circular blades may reduce the matching accuracy between the circular blade and the cutter due to operational errors or component wear, thereby affecting the dimensional accuracy and edge flatness of subsequent cardboard cutting and adversely affecting the stability of product quality.

[0005] Therefore, it is necessary to propose an improved technical solution to address the above problems. Utility Model Content

The cross-section at the position where the lever abuts against the support bars is a cam structure. A downward pressure spring is also provided between the top of the limiting groove and the tensioning slider. Wherein: On the feeding power roller module, one guide roller is rotatably connected between two rotating shaft fixing plates and is connected to the motor through a synchronous belt pulley transmission mechanism. The other guide roller is rotatably connected between two tension sliders. At one end of the two guide rollers, there are meshing gears. The two guide rollers are driven by the gears. In the pre-cutting and post-cutting power roller modules, the power roller is rotatably connected between two rotating shaft fixing plates and is transmitted to the motor through a synchronous belt pulley transmission mechanism.

Furthermore, the distance between the power roller module and the ultrasonic cutter before cutting can be adjusted in parallel to accommodate the conveying needs of different cardboard thicknesses. For thicker cardboard, the distance can be increased to reduce conveying resistance, while for thinner cardboard, the distance can be reduced to ensure stable tension before cutting, preventing wrinkles or shifting of the cardboard during conveying and further improving the accuracy of the cutting edge dimensions. In addition, the high-frequency vibration cutting of the ultrasonic cutter reduces burrs on the cardboard edges. Combined with the circular groove guidance of the feed guide roller and the clamping conveying of the power rollers before and after cutting, the overall cutting edge flatness and operational stability are improved. Simultaneously, the waste discharge trough ensures timely waste discharge, preventing waste accumulation from affecting equipment operation and optimizing the smoothness of automated operations.

Detailed Implementation

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Please see Figure 1-7 In this embodiment of the invention, an ultrasonic paper edge trimming device is used for trimming paperboard. It includes a machine body 10, on which a feeding power roller module 20, a pre-cutting power roller module 30, an ultrasonic cutting module 40, and a post-cutting power roller module 50 are sequentially installed from front to back. A waste discharge groove 60 is also provided on the machine body 10 below the ultrasonic cutting module 40. The feeding power roller module 20 includes two guide rollers 21 with upper and lower power outputs. The surface of the guide roller 21 is surrounded by a plurality of equally spaced circular grooves. The pre-cutting power roller module 30 and the post-cutting power roller module 50 both include a power roller 70 and a pressing roller 80 docked on the power roller 70. The two guide rollers 21 and the power roller 70 and the pressing roller 80 generate a rolling force that propels the paperboard forward. The ultrasonic cutting module 40 includes at least two parallel first sliding rods 41, a first adjusting block 42 slidably connected to the two first sliding rods 41, an ultrasonic cutter 43 fixedly mounted on the first adjusting block 42, two second adjusting blocks 44 fixedly mounted at both ends of the two first sliding rods 41, a second sliding rod 45 slidingly engaged with the second adjusting block 44, and a support rod 46 fixed below both ends of the second sliding rod 45 and fixedly connected to the machine body 10. The first sliding rods 41 and the second sliding rods 45 are perpendicular to each other. A first tightening member (not shown) is provided on both the first adjusting block 42 and the second adjusting block 44. The first tightening member on the first adjusting block 42 abuts against the first sliding rod 41 to fix the first adjusting block 42, and the first tightening member on the second adjusting block 44 abuts against the second sliding rod 45 to fix the second adjusting block 44. The blade of the ultrasonic cutter 43 faces the cutting front power roller module 30.

[0022] When the ultrasonic paper edge trimming device is working, the feeding power roller module 20 first receives the paperboard to be trimmed and printed. The upper and lower guide rollers 21 with equally spaced circular grooves generate rolling force through line contact, which smoothly conveys the paperboard forward to the cutting power roller module 30. The power roller 70 and the pressure roller 80 of the cutting power roller module 30 clamp the paperboard and convey it to the ultrasonic cutting module 40 at a stable speed. The ultrasonic cutting module 40 is fixed to the machine body 10 by the support rod 46. According to production needs, the operator can first loosen the first tightening part on the second adjusting block 44, and move the two second adjusting blocks 44 along the second sliding rod 45 parallel to the paperboard conveying direction. This will drive the two first sliding rods 41 connected to the second adjusting block 44 and the entire ultrasonic cutter 43 assembly to move synchronously, so as to achieve the initial positioning of the distance between the power roller module 30 and the ultrasonic cutter 43 before cutting. Then, loosen the first tightening part on the first adjusting block 42, and finely adjust the position of the first adjusting block 42 along the first sliding rod 41 perpendicular to the paperboard conveying direction, so that the blade of the ultrasonic cutter 43 is accurately aligned with the single side of the paperboard that needs to be cut. After positioning, tighten all the first tightening parts. The ultrasonic cutter 43 starts and cuts the single side of the paperboard through high-frequency vibration. The cutting waste falls into the waste discharge trough 60 below and is discharged. Finally, the cut paperboard is clamped by the power roller 70 and the pressure roller 80 of the power roller module 50 after cutting and continues to be conveyed, completing the entire edge cutting process.

[0023] In the above technical solution, the cutting spacing and edge alignment can be achieved without replacing the cutting tool through the cooperation of the first sliding rod 41, the second sliding rod 45 and the adjusting block, shortening the downtime during order switching, ensuring the continuous operation efficiency of the production line and reducing operating costs. Moreover, the distance between the power roller module 30 and the ultrasonic cutter 43 before cutting can be adjusted in parallel to adapt to the conveying needs of paperboards of different thicknesses. For thicker paperboards, the distance can be increased to reduce conveying resistance, and for thinner paperboards, the distance can be reduced to ensure the tension stability before cutting, avoiding wrinkles or deviations in the paperboard during conveying, and further improving the dimensional accuracy of the cutting edge. In addition, the high-frequency vibration cutting of the ultrasonic cutter 43 can reduce the burrs on the edges of the paperboard. Combined with the circular groove guidance of the feed guide roller 21 and the clamping conveying of the power rollers 70 before and after cutting, the overall cutting edge flatness and operational stability are improved. At the same time, the waste discharge trough 60 enables timely discharge of waste, avoiding waste accumulation from affecting equipment operation and optimizing the smoothness of automated operation.

[0024] Please see Figure 2 The first sliding rod 41 is a round rod structure, and two first sliding rods 41 are provided. The first adjusting block 42 has two through holes that mate with the first sliding rod 41. The first adjusting block 42 is slidably connected to the first sliding rod 41 through the through holes. The first adjusting block 42 also has a first threaded hole 421 that is normally connected to the through holes. The first tightening element of the first adjusting block 42 is a nut screw threaded into the first threaded hole 421. The round rod structure of the first sliding rod 41, combined with the two corresponding through holes on the first adjusting block 42, allows the first adjusting block 42 to slide more smoothly along the first sliding rod 41, avoiding slippage. The jamming phenomenon is eliminated. At the same time, the matching structure of the double through hole and the double round rod can effectively prevent the first adjusting block 42 from deflecting when sliding or fixing, ensuring that the ultrasonic cutter 43 maintains a stable posture during the fine adjustment of the cutting edge position, and improving the accuracy of the cutting edge position. The first tightening part uses a nut screw and is matched with the first threaded hole 421 of the normal connecting through hole. When tightened, it can directly press against the round rod-shaped first sliding rod 41. Not only is the locking operation simple and labor-saving, but the locking strength can also be flexibly controlled by adjusting the tightening force of the nut screw. This avoids the cutter from shifting due to excessively loose locking, and also prevents the surface of the first sliding rod 41 from being damaged by excessively tight locking. The lower end of the first adjusting block 42 has a fixed part 422 formed downwards, and the ultrasonic cutter 43 is fixed on the fixed part 422. This provides a stable installation base for the ultrasonic cutter 43. Compared with adding a fixed component separately, it reduces the vibration transmission error caused by the gap between the components, ensures that the high-frequency vibration of the ultrasonic cutter 43 is more stable when it is working, further improves the flatness of the cut edge, and simplifies the installation and disassembly process of the cutter, making it easier for later maintenance and replacement.

[0025] Please see Figure 2The second sliding rod 45 is a square rod structure, and the second adjusting block 44 is a right-angled structure mounted on the second sliding rod 45. A fixing rod 47 connects the two second adjusting blocks 44, and two rollers 471 are connected to the fixing rod 47 to abut against the lower ends of the two second sliding rods 45, allowing the second adjusting blocks 44 to slide on the second sliding rods 45. At least two second threaded holes 441 are also provided on the second adjusting blocks 44. The first tightening element of the second adjusting block 44 is a nut screw threaded into the second threaded hole 441. The second adjusting block 44 is fixed to the second sliding rod 45 by the upper and lower tightening force applied by the first tightening element and the rollers 471. In this technical solution, due to the limiting effect of the first sliding rod 41, the two second adjusting blocks 44 can restrain the left and right position offset of the two second adjusting blocks 44 by abutting against the two second sliding rods 45 when they cooperate with each other. This prevents the two second adjusting blocks 44 from being too tightly abutted against the second sliding rods 45 due to the tension of the first sliding rod 41 under excessive constraint, which would cause the adjustment to be unsmooth. Therefore, the second sliding rods 45 adopt a square rod structure to cooperate with the right-angled second adjusting blocks 44, which can directly constrain the adjustment through the planar limiting effect of the square rods, thereby improving the adjustment accuracy of the distance between the power roller module 30 and the cutter before cutting. The fixed rod 47 connecting the two second adjusting blocks 44 and the roller 471 on the rod abutting against the lower end of the second sliding rod 45 not only reduce the resistance of the second adjusting block 44 sliding along the square rod through rolling friction, making the spacing adjustment more effortless and smooth, but also form a symmetrical clamping structure with the nut screw above. When the nut screw in the second threaded hole 441 is tightened, the supporting force of the roller 471 on the lower end of the second sliding rod 45 can firmly lock the second adjusting block 44 on the square rod through the clamping force. Its structure is simple and ingenious, which can better cooperate the second adjusting block 44 connected to both ends of the first sliding rod 41 with the second sliding rod 45.

[0026] Please see Figure 3-6 The feeding power roller module 20, the pre-cutting power roller module 30, and the post-cutting power roller module 50 each include a motor 90, a synchronous belt pulley transmission mechanism 91, and two rotating shaft fixing plates 92. The motor 90 is fixedly mounted on the machine body 10, and the two rotating shaft fixing plates 92 are oppositely distributed and vertically mounted on the machine body 10. A limit groove 921 is provided on the rotating shaft fixing plate 92, and a tensioning slider 93 is slidably connected within the limit groove 921. A toggle rod 94 is rotatably connected between the tensioning sliders 93 of the two rotating shaft fixing plates 92, and both ends of the toggle rod 94 extend beyond the other side of the two tensioning sliders 93. Support bars 95 are installed on the opposite surfaces of the two rotating shaft fixing plates 92, and the toggle rod 94 abuts against the support bars 95. The cross-section at the position where the toggle rod 94 abuts against the support bars 95 is a cam structure 941. A compression spring 96 is also provided between the top of the limit groove 921 and the tensioning slider 93. On the feeding power roller module 20, one of the guide rollers 21 is rotatably connected between two rotating shaft fixing plates 92 and is connected to the motor 90 through the synchronous belt pulley transmission mechanism 91. The other guide roller 21 is rotatably connected between two tension sliders 93. At one end of the two guide rollers 21, there are meshing gears 22. The two guide rollers 21 are driven by the gears 22. On the pre-cutting power roller module 30 and the post-cutting power roller module 50, the power roller 70 is rotatably connected between two rotating shaft fixing plates 92 and is transmitted to the motor 90 through the synchronous belt pulley transmission mechanism 91. The pressure roller 80 is rotatably connected between two tension sliders 93.

[0027] In the above technical solution, the motor 90 of each power roller 70 module cooperates with the synchronous belt pulley transmission mechanism 91 to provide a stable and adjustable driving force for the guide roller 21 or the power roller 70, ensuring uniform paperboard conveying speed and avoiding edge deviation caused by power fluctuations; the limiting groove 921, tension slider 93 and pressure spring 96 on the rotating shaft fixing plate 92 form an elastic adjustment structure, which, together with the abutment design of the toggle rod 94 and the support bar 95, can adaptively adjust the distance between the upper and lower guide rollers 21 according to the paperboard thickness; the pressure spring 96 applies continuous and uniform downward pressure to the upper guide roller 21 or pressure roller 80 through the tension slider 93, ensuring that paperboards of different thicknesses can be stably clamped. The conveying mechanism is designed to prevent excessive pressure from deforming the cardboard. Simultaneously, the adjustable sliders 93 extending from both ends of the lever 94, which are connected to the support bar 95 via cam structures 941, allow operators to quickly lift the sliders 93 simply by moving the lever 94. This facilitates cardboard feeding or equipment maintenance, offering greater convenience compared to traditional bolt adjustments. Furthermore, the two guide rollers 21 in the feed roller module 20 are driven by gears 22, ensuring synchronized rotation speeds of the upper and lower guide rollers 21. This further enhances the stability and guidance of cardboard conveying, reducing the risk of cardboard deviation during transport. The overall structure balances the reliability of automated conveying with operational flexibility, adapting to diverse cardboard processing needs in mass production.

[0028] Please see Figure 3-4The feeding power roller module 20 also includes a base plate 23 fixedly mounted on the machine body 10, a T-shaped slide rail 24 fixed in front of the base plate 23, two T-shaped limiting blocks 25 slidably connected to the T-shaped slide rail 24, and two guide rods 26 rotatably connected between two first rotating shaft fixing plates 92. The two first rotating shaft fixing plates 92 are mounted on the base plate 23, the two guide rods 26 are located in front of the two guide rollers 21, and the space between the two guide rods 26 is used to pass through the cardboard. The T-shaped slide rail 24 is located in front of the two guide rods 26. A second tightening member (not shown in the figure) is connected to the T-shaped limiting block 25. The second tightening member abuts against the T-shaped slide rail 24 to fix the T-shaped limiting block 25. In this technical solution, the base plate 23 provides a stable mounting foundation for the first rotating shaft fixing plate 92 and various components, ensuring that the overall structure of the feeding power roller module 20 is not easily deformed during long-term operation and ensuring conveying stability; the two guide rods 26 are located in front of the guide roller 21 and form a cardboard channel, which can initially limit the cardboard before it enters the guide roller 21, preventing the cardboard from being misaligned in the subsequent cutting edge due to the initial position deviation of the cardboard during conveying; and the T-shaped slide rail 24 cooperates with the slidable T-shaped limit block 25, allowing the operator to loosen the second tightening piece according to the width of the cardboard and adjust the two along the T-shaped slide rail 24. The spacing of the T-shaped limiting blocks 25 is designed to match the width of the cardboard, thereby accurately positioning the cardboard again in front of the guide rod 26. This double limiting structure significantly reduces the risk of lateral deviation during cardboard conveying. At the same time, the T-shaped slide rail and the limiting blocks fit tightly, allowing for smooth sliding adjustment and preventing loosening once locked. The second tightening component's clamping and fixing method is simple to operate and can be adjusted without complicated tools. It can quickly adapt to the feeding requirements of cardboard of different widths, further improving the flexibility of the device in handling multi-specification orders in mass production and reducing the adjustment time when switching specifications.

[0029] Please see Figure 1 and Figure 7The machine body 10 has a waste outlet (not shown in the figure) located below the ultrasonic cutting module 40. The waste outlet 60 includes an end plate 61 connected to one side of the waste outlet, two baffles 62 connected to the front and rear sides of the waste outlet, and a guide plate 63 connected to the lower end of the end plate 61 and the baffles 62. The guide plate 63 has a structure design that gradually slopes downward from one side of the end plate 61 to the other side, so that the part of the waste outlet 60 away from the end plate 61 forms a waste outlet (not shown in the figure). The waste is led out along the side of the machine body 10. The waste inlet on the machine body 10 is directly connected to the bottom of the ultrasonic cutting module 40, ensuring that the waste generated during cutting can fall into the waste discharge trough 60 immediately, preventing waste from accumulating in the cutting area and affecting the cutting accuracy of the ultrasonic cutter 43 or the paperboard conveying; the end plate 61 of the waste discharge trough 60 and the two baffles 62 form a three-sided enclosure structure, which can prevent waste from scattering from the side into the machine body 10 or the production environment during the conveying process, keeping the inside of the equipment and the workshop environment clean; the guide plate 63 adopts a design that gradually slopes downward from the end plate 61 to the other side. It can achieve non-powered conveying by the weight of the waste itself, allowing the waste to slide naturally along the inclined surface to the discharge port without the need for additional drive components, thus reducing equipment energy consumption and maintenance costs. The discharge port is set along the side of the machine body 10, which can directly lead the waste to the collection device outside the machine body 10. The staff does not need to frequently open the equipment to clean the waste, which reduces downtime for cleaning and avoids the safety risks that may be caused by manual cleaning. Overall, it optimizes the automation and convenience of waste handling in the mass production process and ensures the continuous and stable operation of the edge cutting operation.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
