Description

Technical Field

[0001] This invention relates to the field of die-cutting machine technology, and in particular to an adaptive material receiving module for a die-cutting machine. Background Technology

[0002] The process of cutting an entire printed product into a single graphic product is called die cutting. Die cutting machines are important equipment for post-printing packaging processing. The working principle of a die cutting machine is to use die cutting blades, steel blades, hardware molds, and templates carved from steel plates. Then, a certain pressure is applied through the printing plate to cut the printed product or cardboard into a certain shape.

[0003] The receiving module of the die-cutting machine is the last stage of the die-cutting machine. The die-cutting machine transports the cut cardboard to the receiving module through the die-cutting machine's conveying module. The receiving module is equipped with a vertically adjustable lifting support and a carrying trolley placed directly on the top of the lifting support to carry the cardboard. The cut cardboard is placed on the top of the carrying trolley, and then the carrying trolley pulls the cut cardboard out of the die-cutting machine's receiving module.

[0004] Regarding the aforementioned technologies, the inventors believe that: the receiving module, driven by a motor combined with sprockets and chains, allows the lifting bracket to slide vertically. However, the lifting bracket, driven by the motor, is prone to vibration. If the carrying trolley is placed directly on top of the lifting bracket, this vibration will cause horizontal displacement between the trolley and the lifting bracket. In this situation, not only will the cardboard be stacked crookedly, but the carrying trolley may even move horizontally until it detaches from the lifting bracket. Summary of the Invention

[0005] To address the issue of the relative horizontal displacement between the carrier trailer and the lifting support caused by vibration when the carrier trailer is placed directly on the top surface of the lifting support, this application provides an adaptive material receiving module for a die-cutting machine.

[0006] This application provides an adaptive material receiving module for a die-cutting machine, which adopts the following technical solution:

[0007] An adaptive receiving module for a die-cutting machine includes a receiving chamber body with a discharge port at its top, a support rod that slides vertically within the receiving chamber body via a linear guide rail, a lifting bracket vertically fixed to the side wall of the support rod away from the discharge port, a carrying trolley disposed on the top surface of the lifting bracket for loading cardboard, and a driving mechanism disposed within the receiving chamber body for driving the lifting bracket to move vertically. The lifting bracket has a cavity, and a locking protrusion is hinged to the inner bottom surface of the cavity. A locking slot is formed on the top surface of the lifting bracket along its length. The end of the locking protrusion protrudes through the locking slot from the top surface of the lifting bracket. A locking mechanism is disposed within the lifting bracket for driving the locking protrusion to insert into the bottom of the carrying trolley.

[0008] By adopting the above technical solution, the operator first pushes the carrier trailer to the top surface of the lifting bracket. The hinged locking protrusion is pressed against the bottom surface of the carrier trailer by the carrier trailer. Due to the action of the locking mechanism, the locking protrusion is inserted into the bottom of the carrier trailer through the carrier groove, thereby fixing the carrier trailer to the top surface of the lifting bracket.

[0009] Optionally, several lifting brackets are arranged along the length of the supporting rod. Adjacent lifting brackets are provided with a release mechanism for releasing the locking protrusion from the connection between the locking protrusion and the carrying trailer. The release mechanism includes a drive slider that slides within the cavity of the lifting bracket via a linear slide rail, and a transmission straight plate that slides between adjacent lifting brackets. Adjacent lifting brackets have vertically formed drive slots on their adjacent sidewalls. The end of the transmission straight plate passes through the drive slot and is fixedly connected to the drive slider. The release mechanism also includes a locking cylinder vertically fixed to the sidewall of the locking protrusion, and a guide straight plate vertically arranged on the sidewall of the locking protrusion. The guide straight plate has a vertically formed guide slot on its sidewall, and the locking cylinder passes through the guide slot into the sidewall of the guide straight plate. A reset mechanism for resetting the locking protrusion is provided between the guide straight plate and the drive slider. The locking mechanism is located between adjacent lifting brackets.

[0010] By adopting the above technical solution, the transmission straight plate drives the drive slider to slide along the length direction of the lifting bracket. The drive slider drives the guide straight plate to move through the reset mechanism. The guide straight plate drives the locking protrusion to rotate through the locking cylinder until the locking protrusion is disengaged from the bottom of the carrying trailer, and the carrying trailer can be moved out of the receiving chamber body.

[0011] Optionally, the reset mechanism includes a telescopic sleeve disposed between the drive slider and the locking protrusion, two telescopic rods respectively passing through the ends of the telescopic sleeve, and a telescopic spring fixed to the near ends of the two telescopic rods, wherein one end of the telescopic rod is fixed to the side wall of the drive slider, and the other end of the telescopic rod is fixed to the side wall of the guide plate; the release mechanism includes a lifting plate fixedly connected to the near side walls of two adjacent lifting brackets, and a plurality of transmission cylinders vertically fixed to the side wall of the transmission plate away from the discharge port, wherein the plurality of transmission cylinders pass through the lifting plate; the release mechanism further includes a limiting panel fixed to the end of the transmission cylinder away from the transmission plate, and a limiting spring fixedly connected between the limiting panel and the near side wall of the lifting plate.

[0012] By adopting the above technical solution, when the operator pushes the carrier trailer to the top of the lifting bracket, the telescopic spring deforms due to the compression of the carrier trailer, causing the locking protrusion to rotate until it fits against the bottom surface of the carrier trailer. Then, the telescopic spring, through its own deformation, drives the locking protrusion to rotate and insert into the carrier groove. When the operator presses the limit panel, the limit spring deforms due to the compression of the limit panel. When the limit panel is no longer pressed, the limit spring, through its own deformation, drives the transmission plate to return to its initial position, so that the transmission plate can perform subsequent operations.

[0013] Optionally, the side wall of the limiting panel is provided with a pressing mechanism to facilitate the operator to press the transmission straight plate. The pressing mechanism includes a transmission bracket fixed to the side wall of the limiting panel away from the lifting straight plate, and a foot pedal is hinged to the ends of several transmission brackets away from the limiting panel. The pressing mechanism also includes a limiting triangular plate fixed to the bottom surface of the transmission bracket and a return spring fixedly connected between the foot pedal and the limiting triangular plate.

[0014] By adopting the above technical solution, the operator presses the foot pedal with their foot. The foot pedal drives the transmission cylinder to slide through the transmission bracket, and the transmission cylinder drives the drive slider to slide along the length of the lifting bracket through the transmission straight plate. The operation is convenient and easy. Since the operator presses the foot pedal with their foot, the overall area of ​​the foot pedal is large enough. To minimize hard collisions between the trailer and the foot pedal, a return spring is fixed between the foot pedal and the limiting triangle plate. The return spring allows the foot pedal to be adjusted at multiple angles. When no external force is applied, the foot pedal always remains vertical.

[0015] Optionally, the receiving chamber body is provided with a drive mechanism for driving the lifting bracket to slide vertically. The drive mechanism includes a first sprocket, a second sprocket, and a winding pulley rotatably mounted on the inner wall of the receiving chamber body, several turns of steel wire rope wound around the circumference of the winding pulley, and a chain vertically fixed to the top surface of the linear guide slider. The second sprocket is located between the first sprocket and the winding pulley, and below the first sprocket and the winding pulley. The chain sequentially wraps around the outer circumference of the first sprocket, the outer circumference of the second sprocket, and the outer circumference of the winding pulley. The end of the chain that is close to the steel wire rope is fixedly connected. The outer wall of the receiving chamber body is provided with a power mechanism for driving the winding pulley to rotate.

[0016] By adopting the above technical solution, the power mechanism drives the winding pulley to rotate, and the winding pulley drives the chain in the linear slide rail to move vertically downward through the wire rope, thereby realizing the drive mechanism to drive the lifting bracket to slide in the vertical direction.

[0017] Optionally, the power mechanism includes a transmission roller shaft rotating on the side wall of the receiving chamber body and a drive motor fixed to the outer side wall of the receiving chamber body, with the output shaft of the drive motor coaxially fixed to the end of the transmission roller shaft; the power mechanism also includes a large pulley and a small pulley rotatably mounted on the outer side wall of the receiving chamber body, and a transmission belt sleeved on the outer circumferential surfaces of the large pulley and the small pulley, with the large pulley coaxially fixedly connected to the winding pulley and the small pulley coaxially fixedly connected to the transmission roller shaft.

[0018] By adopting the above technical solution, the drive motor is powered on to drive the transmission roller shaft to rotate, and the large pulley and the small pulley cooperate through the conveyor belt to realize that the transmission roller shaft drives several winding pulleys to rotate synchronously.

[0019] Optionally, the drive roller shaft is provided with a discharge mechanism to prevent the cardboard from clogging the discharge port. The discharge mechanism includes a plurality of drive rings coaxially mounted on the drive roller shaft and an arc plate fixed to the outer circumferential surface of the drive rings. The arc plate is made of elastic rubber material.

[0020] By adopting the above technical solution, each time the drive roller rotates once, the outer arc surface of the arc plate will pull a layer of cardboard to the top of the carrier trailer. Due to the different diameters of the large and small pulleys, the speeds of the drive roller and the winding pulley are different. This ensures that when a layer of cardboard is stacked on the top of the carrier trailer, the lifting bracket drives the carrier trailer to descend one level, always keeping the top surface of the lifting bracket flush with the bottom surface of the support plate. This demonstrates the carrier trailer's ability to adapt to the stacking of cardboard.

[0021] Optionally, the receiving chamber is provided with a braking mechanism for controlling the start and stop of the drive motor. The braking mechanism includes a pressing plate fixed to the end of the chain near the wire rope, a braking plate fixed to the inner wall of the receiving chamber, and a contact switch installed on the top of the braking plate. The contact switch is electrically connected to the drive motor.

[0022] By adopting the above technical solution, when the suspended carrier trailer is about to touch the ground, the pressure plate moves vertically downward with the steel wire rope until the pressure plate presses the contact switch, and the carrier trailer stops descending as the drive motor is de-energized.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Each time the drive roller rotates once, the outer arc surface of the arc plate pulls a layer of cardboard to the top of the carrier trailer. Due to the different diameters of the large and small pulleys, the drive roller and the winding pulley rotate at different speeds. This allows the lifting bracket to lower the carrier trailer by one level each time a layer of cardboard is stacked on top of the carrier trailer, keeping the top surface of the lifting bracket flush with the bottom surface of the support plate. This demonstrates the carrier trailer's ability to adapt to the stacking of cardboard.

[0025] 2. When the suspended trailer is about to touch the ground, the pressure plate moves vertically downward with the wire rope until the pressure plate presses the contact switch, and the trailer stops descending as the drive motor is de-energized. Attached Figure Description

[0040] Reference Figure 1 and Figure 5 The receiving chamber body 11 has two side walls equipped with drive devices 48 for vertically sliding the lifting bracket 16. Each drive device 48 includes a first rotating shaft 49, a second rotating shaft 50, and a third rotating shaft 51 that pass through the side walls of the receiving chamber body 11. The first rotating shaft 49, second rotating shaft 50, and third rotating shaft 51 are arranged sequentially from front to back. The first rotating shaft 49 and third rotating shaft 51 are installed at the same level, while the second rotating shaft 50 is located below the first rotating shaft 49 and third rotating shaft 51. The distance between the first rotating shaft 49 and third rotating shaft 51 and the second rotating shaft 50 is equal. A first sprocket 52 is coaxially fixed to the end of the first rotating shaft 49 located inside the receiving chamber body 11. A second sprocket 53 is coaxially fixed to the end of the second rotating shaft 50 located inside the receiving chamber body 11.

[0041] Reference Figure 1 and Figure 6The receiving chamber body 11 is equipped with a braking device 57 for controlling the start and stop of the drive motor 44. The braking device 57 includes a braking plate 58 fixed to the inner wall of the receiving chamber body 11, and a chain 56 passes through the braking plate 58 vertically. A clearance groove 59 is provided on the top surface of the braking plate 58, and a contact switch 60 is fixed to the braking plate 58 through the clearance groove 59. The contact switch 60 is electrically connected to the drive motor 44. A pressing plate 61 is horizontally fixed to the end where the chain 56 and the wire rope 55 are combined, and the wire rope 55 passes through the pressing plate 61 vertically. The ends of the two third shafts 51 away from the winding pulley 54 protrude from the side wall of the receiving chamber body 11, and a large pulley 62 is coaxially fixed to the ends of the two third shafts 51 away from the winding pulley 54. Small pulleys 63 are coaxially fixed to the circumference of both ends of the transmission roller shaft 42, and the small pulleys 63 are located on the outside of the receiving chamber body 11. A transmission belt 64 is fitted between the large pulley 62 and the small pulley 63 on the same side wall of the receiving chamber body 11.

[0042] The implementation principle of the adaptive receiving module of the die-cutting machine in this embodiment is as follows: The operator first pushes the carrying trolley 17 to the top surface of the lifting bracket 16. The locking protrusion 33 is pressed against the bottom surface of the carrying trolley 17 by the carrying trolley 17 until the locking protrusion 33 is inserted into the bottom of the carrying trolley 17 through the carrying groove 28, thereby fixing the carrying trolley 17 to the top surface of the lifting bracket 16. The drive motor 44 is energized and rotates, driving the transmission roller shaft 42 to rotate in the opposite direction. The transmission roller shaft 42 drives the lifting bracket 16 to slide vertically to the top of the receiving cavity body 11. At this time, the top surface of the lifting bracket 16 is flush with the bottom surface of the support plate 13. The conveying module of the die-cutting machine will transport the cardboard to the receiving cavity body 11 through the discharge port 12. The drive motor 44 is energized and drives the transmission roller shaft 42 to rotate in the forward direction. The transmission roller shaft 42 drives the arc plate 47 installed on its periphery to rotate. Each time the drive roller 42 rotates once, the outer arc surface of the arc plate 47 will pull a layer of cardboard to move to the top surface of the carrying trailer 17.

[0043] The small pulley 63 on the side of the transmission roller shaft 42 drives the large pulley 62 on the side of the third rotating shaft 51 to rotate via the transmission belt 64. The large pulley 62 drives the winding pulley 54 to rotate via the third rotating shaft 51. The winding pulley 54 drives the chain 56 in the linear slide rail 34 to move vertically downward via the wire rope 55. This enables the lifting bracket 16 to lower the carrying trailer 17 by one step when each layer of cardboard is stacked on the top surface of the carrying trailer 17, always keeping the top surface of the lifting bracket 16 flush with the bottom surface of the support plate 13. This demonstrates the ability of the carrying trailer 17 to adapt to the stacking of cardboard.

[0044] As the suspended carrier trailer 17 is about to touch the ground, the pressure plate 61 moves vertically downward along with the wire rope 55 until it presses the contact switch 60, at which point the carrier trailer 17 stops descending as the drive motor 44 is de-energized. The operator presses the foot pedal 26 with their foot, which drives the transmission cylinder 22 to slide via the transmission bracket 25. The transmission cylinder 22 drives the drive slider 32 to slide along the length of the lifting bracket 16 via the transmission plate 21. The drive slider 32 drives the guide plate 38 to move via the telescopic sleeve 35 and the telescopic rod 36. The guide plate 38 drives the locking protrusion 33 to rotate via the locking cylinder 40 until the locking protrusion 33 is disengaged from the bottom of the carrier trailer 17, at which point the carrier trailer 17 can be moved out of the receiving chamber body 11.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
