Description

Technical Field

[0001] This application relates to the field of cardboard cutting, and more specifically, to a semi-automatic die-cutting machine. Background Technology

[0002] The use of corrugated cardboard is becoming increasingly widespread. Many products are packaged using corrugated cardboard during the sales process. Corrugated cardboard has low manufacturing costs, effectively protects products after packaging, and facilitates transportation and storage, making it popular with both manufacturers and consumers. During the corrugated cardboard processing, the formed cardboard needs to be cut to specific dimensional requirements to facilitate processing.

[0003] During the cutting process of cardboard boxes, a conveyor belt moves the cardboard, and a cutter cuts it. When the cutter cuts the cardboard, the conveyor belt stops, and the motor driving the conveyor belt must also stop. After the cutter cuts the cardboard, the motor restarts. This frequent starting and stopping of the motor during repeated cutting reduces its lifespan. Summary of the Invention

[0004] To reduce the repeated starting and stopping of the motor driving the conveyor belt, this application provides a semi-automatic die-cutting machine.

[0005] This application provides a semi-automatic die-cutting machine, which adopts the following technical solution:

[0006] A semi-automatic die-cutting machine includes a machine body and a conveyor belt. The machine body includes a movable frame and a driving component. The driving component drives the movable frame to move vertically. The movable frame is equipped with a cutter and a partition plate. The conveyor belt is equipped with a drive motor and a drive rod. The drive motor drives the drive rod to rotate. The conveyor belt includes a rotating roller. A fixed plate is coaxially connected to the rotating roller. A sliding rod and a retaining spring are provided at the end of the fixed plate away from the rotating roller. A sliding plate slides on the sliding rod in the same direction as the length of the sliding rod. The sliding plate is circumferentially fixed to the sliding rod. A retaining spring is connected to the end of the sliding plate near the fixed plate. The spring force of the retaining spring causes the sliding plate to press against the drive rod. When the driving component drives the movable frame to move downward, the cutter moves towards the conveyor belt, and the partition plate causes the sliding plate to slide away from the drive rod.

[0007] With the above technical solution, when the sliding plate abuts against the drive rod, the drive rod drives the sliding plate to rotate to control the rotation of the roller. When the drive component drives the cutter to move closer to the conveyor belt, the sliding plate separates from the drive rod when the partition plate moves, causing the roller to stop rotating. When the drive component drives the cutter to move away from the conveyor belt, the clamping spring causes the sliding plate to abut against the drive rod, and the roller rotates again. This eliminates the need to repeatedly start and stop the drive motor, allowing the drive motor to operate normally and extending its service life.

[0008] Furthermore, the drive rod is equipped with a drive plate, which is located at the end of the drive rod near the sliding plate. The vertical cross-sectional area of ​​the drive plate is larger than the vertical cross-sectional area of ​​the drive rod. The elastic force of the clamping spring causes the sliding plate to press against the drive plate, thereby pressing against the drive rod.

[0009] By using the above technical solution, a drive plate is set up, which increases the contact area with the sliding plate, making it easier to drive the sliding plate and the roller to rotate when the drive plate and the sliding plate are pressed together.

[0010] Furthermore, the drive plate has an insert at one end near the sliding plate, and the sliding plate has an insert hole at one end near the drive plate for the insert to be inserted.

[0011] The above technical solution involves setting up inserts and holes, with the inserts embedded in the holes. When the inserts are embedded in the holes, the drive plate and the sliding plate are more tightly fixed, making it easier for the drive plate to control the rotation of the rollers.

[0012] Furthermore, the sliding plate is provided with an inclined surface, which is located at one end of the sliding plate near the drive plate and extends toward the drive plate in a direction close to the center of the sliding plate.

[0013] With the above technical solution, an inclined surface is set. When the partition plate moves down and presses against the inclined surface, the inclined surface is subjected to the horizontal component of the force when the partition plate is pressed down, making it easier for the sliding plate to slide away from the drive plate. Moreover, compared with the sliding plate and the drive plate being completely attached, the setting of the inclined surface makes it easier for the partition plate to separate the sliding plate and the drive plate from the point of contact between the two.

[0014] Furthermore, the partition plate is provided with an inclined surface two, which is located at one end of the partition plate near the sliding plate and at the corner of the partition plate. The inclined direction of the inclined surface two is parallel to the inclined direction of the inclined surface one. When the partition plate moves down, the inclined surface two abuts against the inclined surface one.

[0015] By using the above technical solution, an inclined surface two is set, and the inclined surface two is located at the corner of the partition plate. When the partition plate moves down, the inclined surface two fits and abuts against the inclined surface one, which reduces the wear between the partition plate and the sliding plate.

[0016] Furthermore, the sliding plate is provided with a sliding hole, the side wall of the sliding hole is provided with a fixing groove, and the sliding rod is provided with a protrusion, the protrusion being embedded in the fixing groove.

[0017] The above technical solution involves setting a fixed groove and a protrusion. The protrusion is embedded in the fixed groove to reduce the circumferential rotation of the sliding plate around the sliding rod, so that when the sliding plate and the drive plate are in contact, the sliding plate and the rotating roller rotate together.

[0018] Furthermore, the end of the protrusion away from the axis of the sliding rod has a gap with the bottom of the fixing groove.

[0019] The above technical solution reduces the contact area between the protrusion and the sliding rod, resulting in less friction on the sliding plate as it slides along the axis of the sliding rod. This reduces the impact on the horizontal sliding of the sliding plate while restricting its rotation, making the overall sliding more stable.

[0020] Furthermore, the machine body includes a storage rack, on which cardboard boxes located on the conveyor belt are cut by a knife and enter the storage rack. The storage rack has a sliding storage plate, which slides vertically. The machine body is provided with a return spring, and the elastic force of the return spring restricts the downward movement of the storage plate.

[0021] With the above technical solution, a storage board and a return spring are set up. When the cut cardboard is conveyed to the storage board by the conveyor belt, the return spring restricts the storage board from moving down. In actual use, by setting a return spring with a suitable elastic coefficient, the distance between the uppermost storage board and the ground is always maintained at a certain distance when the cardboard is conveyed to the storage board, which reduces the situation of the cardboard hitting the storage rack and causing wear when it is conveyed to the storage board.

[0022] Furthermore, the storage rack is equipped with two storage baffles, both of which are vertical in length. The storage plate slides on the storage baffles. The storage baffles are equipped with buffers that the storage plate abuts against, and the buffers restrict the movement of the storage plate.

[0023] By using the above technical solution, a buffer is set up so that when the cardboard is conveyed to the top of the storage board, the storage board moves down, the return spring contracts and generates a certain vibration, and the setting of the buffer reduces the vibration of the return spring.

[0024] Furthermore, the storage baffle is provided with a storage groove, and the buffer includes a limiting spring and a limiting plate. The limiting plate slides horizontally in the storage groove, and the limiting plate is provided with a guide surface that extends upward toward the storage groove. The limiting spring is located in the storage groove and abuts against the limiting plate. When the storage plate moves downward, the storage plate abuts against the guide surface, and the limiting plate moves toward the limiting spring, causing the limiting spring to contract.

[0025] With the above technical solution, when the storage plate moves down, the force on the return spring is reduced by the contact of the guide surface, which reduces the vibration of the storage plate. When the storage plate is below the limiting plate, the staff removes the cardboard from the storage plate, the return spring pushes the storage plate upward, and the limiting plate presses against the upper surface of the storage plate to prevent the storage plate from moving up suddenly.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] (1) By setting a partition plate, when the drive unit drives the cutter to move, the partition plate moves together and the sliding plate separates from the drive rod, so that the motor continues to run while the roller stops rotating, thus extending the service life of the motor.

[0028] (2) By setting up inserts and holes, the interlocking of the inserts and holes is tight, making the drive plate and the sliding plate fit more closely;

[0029] (3) By setting a limit spring and a limit plate, the vibration of the storage plate is reduced, and the situation of the storage plate suddenly moving upward is also reduced. Attached Figure Description

[0037] The present application is further described in detail below with reference to the accompanying drawings.

[0038] This application discloses a semi-automatic die-cutting machine.

[0039] Example:

[0040] See Figure 1 and Figure 2A semi-automatic die-cutting machine for cutting cardboard boxes includes a machine body 1 and a conveyor belt 2. The machine body 1 is equipped with a movable frame 3 and a fixed rod 4. The movable frame 3 slides on the machine body 1. The lower end face of the movable frame 3 is equipped with a cutter 5 and a partition plate 6. The cutter 5 is used to cut the cardboard boxes. The fixed rod 4 is located on the machine body 1 and above the movable frame 3. The fixed rod 4 is equipped with a driving component 7, which is used to drive the movable frame 3 to move vertically. In actual use, the driving component 7 is a cylinder. Both the movable frame 3 and the fixed rod 4 can be replaced as a whole.

[0041] When the drive unit 7 drives the moving frame 3 to move downward, the cutter 5 located on the lower end face of the moving frame 3 and the partition plate 6 move downward together. When the cutter 5 touches the upper end face of the conveyor belt 2, the drive unit 7 stops driving the moving frame 3 to move downward and drives the moving frame 3 to move upward again. The cardboard of the conveyor belt 2 is cut by repeating the above operation.

[0042] The conveyor belt 2 includes a rotating roller 8, which is coaxially connected to a fixed plate 9. The fixed plate 9 is provided with a sliding rod 10 and a retaining spring 11, both located at the end of the fixed plate 9 away from the rotating roller 8. The sliding rod 10 is provided with a sliding plate 28, with the retaining spring 11 connected to the end of the sliding plate 28 closest to the rotating roller 8. The sliding plate 28 has a through sliding hole 12, through which the sliding plate 28 slides, with the sliding direction of the sliding plate 28 being the length direction of the sliding rod 10. The side wall of the sliding hole 12 is provided with a fixing groove 13, and the sliding rod 10 is provided with a protrusion 14. The protrusion 14 is embedded in the fixing groove 13 to restrict the sliding plate 28 from rotating circumferentially relative to the sliding rod 10. The end of the protrusion 14 away from the axis of the sliding rod 10 has a gap with the bottom of the fixing groove 13 to reduce the frictional force received by the sliding plate 28 during sliding.

[0043] See Figure 2 and Figure 3 The conveyor belt 2 is equipped with a drive motor 15 and a drive rod 16. Both the drive motor 15 and the drive rod 16 are located on the side of the sliding plate 28 away from the rotating roller 8. The drive motor 15 is used to drive the drive rod 16 to rotate. The end of the drive rod 16 near the sliding plate 28 is provided with a drive plate 17. The vertical cross-sectional area of ​​the drive plate 17 is larger than the vertical cross-sectional area of ​​the drive rod 16. The elastic force of the clamping spring 11 makes the sliding plate 28 press against the drive plate 17. The setting of the drive plate 17 increases the contact area with the sliding plate 28, which makes it easier for the drive motor 15 to drive the drive plate 17 to rotate and drive the rotating roller 8 to rotate together.

[0044] See Figure 3 and Figure 4The sliding plate 28 has an inclined surface 18, which is located at the end of the sliding plate 28 near the drive plate 17. The inclined surface 18 extends from the center of the sliding plate 28 toward the drive plate 17. The partition plate 6 has an inclined surface 19, which is located at the end of the partition plate 6 near the sliding plate 28 and at the corner of the partition plate 6 near the cutter 5. The inclined direction of the inclined surface 19 is parallel to the inclined direction of the inclined surface 18. When the partition plate 6 moves downward, the inclined surface 19 abuts against the inclined surface 18. The arrangement of the inclined surfaces 18 and 19 reduces the contact wear between the partition plate 6 and the sliding plate 28, and when the partition plate 6 abuts against the sliding plate 28, the sliding plate 28 receives a larger component force toward the rotating roller 8, making it easier for the sliding plate 28 to separate from the drive plate 17.

[0045] See Figure 4 and Figure 5 The drive plate 17 is provided with an insert 20, which is located at one end of the drive plate 17 near the sliding plate 28. The sliding plate 28 is provided with an insert hole 21, which is located at one end of the sliding plate 28 near the drive plate 17 and at a position where the inclined surface 18 is not provided. The insert hole 21 is for the insert 20 to be inserted. When the sliding plate 28 moves toward the drive plate 17, the insert 20 is inserted into the insert hole 21. The drive plate 17 drives the sliding plate 28 to rotate, thereby driving the rotating roller 8 to rotate. In actual use, the side wall of the insert hole 21 near the drive plate 17 can be provided with a fitting slope to facilitate the insertion of the insert 20. The fitting slope extends toward the inclined surface in the direction of the drive plate 17.

[0046] When the drive unit 7 drives the moving frame 3 to move downward, the cutter 5 moves toward the conveyor belt 2, and the partition plate 6 moves toward the sliding plate 28. Subsequently, when the inclined surface 19 of the partition plate 6 abuts against the inclined surface 18 of the sliding plate 28, the horizontal component of the force of the partition plate 6 causes the sliding plate 28 to move away from the drive plate 17, and causes the insert 20 to disengage from the hole 21.

[0047] See Figure 1 and Figure 6The machine body 1 is equipped with a storage rack 22, located on one side of the conveyor belt 2, for storing cut cardboard boxes. The storage rack 22 has two storage baffles 23, one on each side of the rack 22, with a storage plate 29 sliding between them in a vertical direction. The machine body 1 has a return spring 24, with a sliding plate 28 located on the lower surface of the storage plate 29. The spring force of the return spring 24 restricts the downward movement of the storage plate 29. When the return spring 24 is normally extended, the height of the upper surface of the storage plate 29 is lower than the height of the upper surface of the conveyor belt 2. In actual use, when cardboard boxes cut by the cutter 5 are conveyed to the storage plate 29 via the conveyor belt 2, the spring coefficient of the return spring 24 is set to ensure that the height of the uppermost cardboard box on the storage plate 29 from the ground is always maintained at the required height.

[0048] The storage baffle 23 is provided with a storage groove 25, which is located at one end of the storage baffle 23 that is close to each other. The storage baffle 23 is provided with a buffer 26, which is used by the storage plate 29 to abut against, and the buffer 26 restricts the movement of the storage plate 29. The buffer 26 includes a limiting plate 262 and a limiting spring 261. The limiting plate 262 slides horizontally in the receiving groove 25. The limiting spring 261 is located at the bottom of the receiving groove 25. One end of the return spring 24 abuts against the bottom of the receiving groove 25 and the other end is connected to the limiting plate 262. The elastic force of the return spring 24 restricts the limiting plate 262 from moving towards the bottom of the receiving groove 25. The limiting plate 262 is provided with a guide surface 27. The guide surface 27 is located at the end of the limiting plate 262 away from the bottom of the receiving groove 25 and extends upward towards the receiving groove 25. When the receiving plate 29 moves downward, the receiving plate 29 abuts against the guide surface 27, and the limiting plate 262 moves towards the limiting spring 261 and causes the limiting spring 261 to contract.

[0049] The working principle of this embodiment is as follows:

[0050] When the machine body 1 is running, the rotating roller 8 drives the conveyor belt 2 to run, and the conveyor belt 2 carries the cardboard. When the cardboard moves to below the cutter 5, the drive unit 7 drives the moving frame 3 to move closer to the conveyor belt 2. This causes the cutter 5 to move closer to the conveyor belt 2. When the cutter 5 moves closer to the conveyor belt 2, the inclined surface 19 of the partition plate 6 presses against the inclined surface 18 of the sliding plate 28, causing the sliding plate 28 to move away from the drive plate 17 and disengage the insert 20 from the insertion hole 21. At this time, the rotating roller 8 stops rotating, the conveyor belt 2 stops running, and the cutter 5 continues to move downward and cut the cardboard. When the cutter 5 moves upward, the retaining spring 11 pushes the sliding plate 28 closer to the drive plate 17, causing the insert 20 to embed into the insertion hole 21. At this time, the rotating roller 8 rotates again, and the conveyor belt 2 continues to transport the cardboard.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
