Description

Technical Field

[0001] This application relates to the field of lunchbox production equipment, and in particular to a high-efficiency punching and cutting device. Background Technology

[0002] The process of producing lunch boxes involves first producing sheet material, then pressing individual lunch boxes onto a single sheet material using a mold, and finally cutting the lunch boxes off the sheet material using a punching and cutting device.

[0003] Different lunch boxes require different upper die cutting. After changing the upper die, the vertical position of the upper die needs to be constantly adjusted during the trial run so that the upper die is positioned just to cut the lunch box.

[0004] However, during the trial run, it is usually necessary to stop the machine to adjust the position of the upper die, which requires the production line to be repeatedly started and stopped, which is quite inconvenient. Summary of the Invention

[0005] To address the issue of repeated start-ups and shutdowns of the production line during die-cutting debugging, this application provides a highly efficient debugging punching and cutting device.

[0006] This application provides a high-efficiency punching and cutting device, which adopts the following technical solution:

[0007] A high-efficiency punching and cutting equipment includes a base, a tool holder, and a drive mechanism that drives the tool holder to move vertically. A support is fixed to the top of the base, and a fixing plate is fixed to the top of the support. The fixing plate and the top surface of the base are spaced apart.

[0008] The tool holder is located between the top surface of the base and the fixed plate. The top of the fixed plate is provided with several vertical guide columns. A mounting plate is slidably connected to the guide columns. The sliding direction of the mounting plate is vertical. The driving mechanism is located on the mounting plate. The driving mechanism is connected to a connecting column. The bottom end of the connecting column passes through the fixed plate and is connected to the tool holder.

[0009] An automatic telescopic mechanism for adjusting the distance between the mounting plate and the fixed plate is provided between the fixed plate and the mounting plate.

[0010] By adopting the above technical solution, after replacing the die, if the die height needs to be adjusted during the trial run, the height of the mounting plate can be adjusted via the automatic telescopic mechanism without stopping the production line. Furthermore, the die holder is directly connected to the mounting plate via a connecting column, meaning the automatic telescopic mechanism only needs to support the die holder, connecting rod, mounting plate, and drive mechanism, reducing the load on the automatic telescopic mechanism and extending its service life.

[0011] Optionally, the automatic telescopic mechanism includes a threaded sleeve, a threaded column, an adjusting gearbox, and an adjusting motor. The threaded sleeve is fixed to the top surface of the fixed plate, the adjusting gearbox is fixed to the mounting plate, the input end of the adjusting gearbox is drivenly connected to the rotating shaft of the adjusting motor, the output end of the adjusting gearbox is coaxially fixed to the threaded column, the threaded column is threadedly connected to the threaded sleeve, and the axis of the threaded column is in the vertical direction.

[0012] By adopting the above technical solution, the speed of the motor is adjusted by regulating the speed of the gearbox, which in turn drives the threaded column to rotate. This causes the threaded column to rise or fall within the threaded sleeve, thereby raising or lowering the mounting plate and tool holder. The motor is connected to the production management system, and the number of rotations of the motor can be controlled via the control panel of the production management system, thus controlling the lifting height of the tool holder.

[0013] Optionally, the outer wall of the threaded post is provided with an external thread, and the pitch of the external thread is 0.01 mm.

[0014] By adopting the above technical solution, the position of the cutter holder can be finely adjusted, making the cutting position of the lunchbox more precise. During operation, the upper die is installed on the cutter holder, and the lower die is installed on the top surface of the base. If the upper die is positioned too high, the lunchbox will be difficult to cut; if the upper die is positioned too low, the overlapping area between the upper and lower dies will be too large, resulting in faster blade wear and reduced blade life.

[0015] Optionally, the regulating motor is a servo motor.

[0016] By adopting the above technical solutions, servo motors are easier for production management systems to control, resulting in precise and more sensitive control.

[0017] Optionally, the connecting column includes an upper fixed column, a lower fixed column, and a rotating column connecting the upper fixed column and the lower fixed column. The top end of the rotating column is coaxially rotatably connected to the upper fixed column, and the bottom end of the rotating column is threadedly connected to the lower fixed column. The upper fixed column is connected to a driving mechanism, and the lower fixed column is connected to the top surface of the tool holder.

[0018] By adopting the above technical solution, when a significant adjustment of the tool holder height is required, manual rotation of the rotating column can be used for adjustment, which is more efficient. Then, a trial run and debugging can be conducted, and an automatic telescopic mechanism can be used for fine-tuning of the height.

[0019] Optionally, the drive mechanism includes a drive reduction gearbox, a drive motor, an eccentric wheel, and a wheel ring. The drive reduction gearbox is fixed to the mounting plate. The shaft of the drive motor is coaxially fixed to the input end of the drive reduction gearbox. The output shaft of the drive reduction gearbox is connected to the eccentric wheel. The wheel ring is sleeved on the eccentric wheel. The top end of the connecting column is fixed to the bottom end of the wheel ring. The bottom end of the connecting column is hinged to a tool holder.

[0020] By adopting the above technical solution, using an eccentric wheel structure instead of a hydraulic cylinder structure to drive the vertical movement of the tool holder, the punching process becomes more stable and the punching speed is faster.

[0021] Optionally, the eccentric wheel, the wheel ring, and the connecting column are provided in two sets. The two eccentric wheels are symmetrically arranged on both sides of the drive reduction gearbox, and the connecting column is symmetrically connected to both sides of the center of gravity of the tool holder.

[0022] By adopting the above technical solution, two eccentric wheels are symmetrically arranged on both sides of the drive reduction gearbox, which makes the reduction gearbox run stably. The connecting column is symmetrically connected to both sides of the center of gravity of the tool holder, which makes the sliding of the tool holder stable.

[0023] Optionally, the support portion consists of four support columns fixed to the four corners of the fixing plate, and a slide cylinder is fixed on the tool holder. The slide cylinder is sleeved on the support column, and the inner wall of the slide cylinder slides to contact the outer wall of the support column.

[0024] By adopting the above technical solution, the sliding cylinder is sleeved on the support column, which makes the sliding of the sliding cylinder more stable and improves the sliding stability of the tool holder.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When the height of the die needs to be adjusted, the height of the mounting plate is adjusted by an automatic telescopic mechanism, without stopping the production line;

[0027] 2. The tool holder is directly connected to the mounting plate via a connecting column, so that the automatic telescopic mechanism only needs to support the tool holder, connecting rod, mounting plate and drive mechanism, reducing the weight load of the automatic telescopic mechanism and improving its service life.

[0028] 3. When a significant adjustment to the tool holder height is required, manual rotation of the rotating column is a more efficient method.

[0029] 4. Two eccentric wheels are symmetrically arranged on both sides of the drive reduction gearbox to ensure stable operation of the reduction gearbox. The connecting columns are symmetrically connected to both sides of the center of gravity of the tool holder to ensure stable sliding of the tool holder. Attached Figure Description

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1

[0036] Embodiment 1 of this application discloses a high-efficiency punching and cutting device. This high-efficiency punching and cutting device is used on a lunch box production line to precisely punch off pre-formed but uncut lunch boxes from a whole sheet.

[0037] Reference Figure 1 , Figure 2 The efficient punching equipment includes a base 1, a tool holder 3, and a drive mechanism 4. A support part 2 is fixed to the top of the base 1, and a fixing plate 21 is fixed to the top of the support part 2. In this embodiment, the support part 2 consists of four vertically arranged support columns, which are respectively fixed below the four corners of the rectangular fixing plate 21, supporting the fixing plate 21 above the top surface of the base 1, with the fixing plate 21 spaced apart from the top surface of the base 1.

[0038] The tool holder 3 is used to mount the upper die (not shown in the figure), which is located in the space between the top surface of the base 1 and the fixing plate 21. Slide cylinders 31 are fixed at the four corners of the tool holder 3. Each slide cylinder 31 is fitted onto a support column, and the inner wall of the slide cylinder 31 slides against the outer wall of the support column, allowing the tool holder 3 to slide precisely vertically along the support column without horizontal offset or wobbling, ensuring smooth operation of the tool holder 3.

[0039] Several guide posts 5 are vertically fixed to the top of the fixed plate 21. A sliding hole is provided on the mounting plate 6 for the guide posts 5 to pass through, and the guide posts 5 are slidably connected to the mounting plate in the sliding hole in the vertical direction. A drive mechanism 4 is mounted on the mounting plate 6 to provide punching power. The drive mechanism drives the tool holder 3 to reciprocate vertically.

[0040] Reference Figure 2 The drive mechanism 4 includes a drive reduction gearbox 41, a drive motor (not shown in the figure), an eccentric wheel 42, and a wheel ring 43. The drive reduction gearbox 41 is fixed on the top surface of the mounting plate 6. The shaft of the drive motor is coaxially and fixedly connected to the input end of the drive reduction gearbox 41. The output shaft of the drive reduction gearbox 41 is connected to the eccentric wheel 42, and the wheel ring 43 is sleeved on the eccentric wheel 42.

[0041] The top end of the connecting column 7 is fixedly connected to the bottom end of the wheel ring 43. The bottom end of the connecting column 7 passes through the fixing plate 21 and is connected to the top surface of the tool holder 3 by hinge. When the drive motor is running, the rotational motion of the eccentric wheel 42 is converted into the reciprocating punching motion of the tool holder 3 in the vertical direction through the wheel ring 43 and the connecting column 7.

[0042] The output shaft of the drive reduction gearbox 41 is bidirectional, and the drive mechanism 4 is equipped with two sets of power output units. Each power output unit includes an eccentric wheel 42, a wheel ring 43, and connecting columns 7. Two eccentric wheels 42 are symmetrically connected to both sides of the drive reduction gearbox 41, and a wheel ring 43 is fitted onto each eccentric wheel 42. The top ends of the two connecting columns 7 are fixedly connected to the two wheel rings 43, and the bottom ends of the two connecting columns 7 are symmetrically hinged to the top surface of the tool holder 3, with the two hinge points located on either side of the center of gravity of the tool holder 3.

[0043] The symmetrical dual-drive design ensures that the driving force of the drive mechanism 4 acts evenly and in a balanced manner on the tool holder 3, preventing the tool holder 3 from tilting or jamming during high-speed reciprocating motion, thus ensuring the stability of the punching process and the life of the equipment. It is suitable for large or wide-width die-cutting molds.

[0044] An automatic telescopic mechanism 8 is provided between the fixed plate 21 and the mounting plate 6. The automatic telescopic mechanism 8 includes a threaded sleeve 81, a threaded post 82, an adjusting gearbox 83, and an adjusting motor. The threaded sleeve 81 is fixedly installed at the center of the top surface of the fixed plate 21. The adjusting gearbox 83 is fixedly installed at the center of the bottom surface of the mounting plate 6. The adjusting motor is a servo motor, and its shaft is coaxially fixedly connected to the input end of the adjusting gearbox 83. The output end of the adjusting gearbox 83 is coaxially fixed to the threaded post 82. The axis of the threaded post 82 is vertical, and its lower end is screwed into and threadedly connected to the threaded sleeve 81. The outer wall of the threaded post 82 has external threads with a pitch of 0.01 mm.

[0045] The working principle of the high-efficiency punching equipment in Embodiment 1 of this application is as follows: During production, the adjusting motor remains stationary, the length of the automatic telescopic mechanism 8 is fixed, and the relative positions of the mounting plate 6 and the fixed plate 21 are locked. At this time, the drive mechanism 4 drives the tool holder 3 to move up and down within its stroke range through the connecting column 7 to perform punching operations.

[0046] When adjusting the cutter height after replacing the upper die, if the cutter height is incorrect and further adjustment is needed, the operator does not need to stop the machine. The adjusting motor can be started via the control panel on the production management system, and the number of rotations can be set. This, in turn, drives the threaded column 82 to rotate via the adjusting gearbox 83. Since the threaded sleeve 81 remains stationary, the rotation of the threaded column 82 translates into a slight vertical movement of the adjusting gearbox 83 along with the entire mounting plate 6 along the guide column 5. The up-and-down movement of the mounting plate 6 synchronously changes the initial reference position of the drive mechanism 4, thereby indirectly and precisely fine-tuning the overall working range of the cutter holder 3 in the vertical direction. This allows for non-stop fine-tuning, facilitating the rapid adjustment of the newly installed upper die to the critical position where it can just cut the lunchbox. The entire production line does not need to be stopped, achieving efficient and continuous debugging.

[0047] Example 2

[0048] The difference between Embodiment 2 and Embodiment 1 in this application is that, referring to... Figure 3 In this embodiment 2, the connecting column 7 includes an upper fixed column 71, a lower fixed column 73, and a rotating column 72 connecting the two. The top end of the upper fixed column 71 is connected to the wheel ring 43 of the drive mechanism 4. The top end of the rotating column 72 is coaxially rotatably connected to the upper fixed column 71 via a bearing component. The bottom end of the rotating column 72 is threaded, and the top end of the lower fixed column 73 is threaded. The bottom end of the rotating column 72 is threadedly connected to the internally threaded hole at the top end of the lower fixed column 73. The bottom end of the lower fixed column 73 is hinged to the top surface of the tool holder 3.

[0049] The working principle of the high-efficiency punching equipment in Embodiment 2 of this application is as follows: After changing the tool, the worker first manually rotates the rotating column 72 to roughly adjust the position of the tool holder 3, and then the automatic telescopic mechanism 8 is used for trial operation for fine adjustment.
