Description

Technical Field

[0001] This application belongs to the technical field of carton processing equipment, and particularly relates to a stacking mechanism for a corrugated carton printing machine. Background Technology

[0002] After printing, the cardboard boxes need to be laminated. During this process, the cardboard boxes must be fed one by one into the laminating equipment. The traditional method involves workers manually placing the cardboard boxes one by one onto a conveyor belt, which then transports the cardboard to the laminating equipment. This method relies on manual operation, is inefficient, and makes it difficult to ensure continuous feeding, which affects the smooth progress of the laminating process.

[0003] Therefore, a mechanism is needed to stack printed cardboard boxes to facilitate subsequent lamination work. Utility Model Content

[0004] The purpose of this application is to provide a stacking mechanism for a corrugated cardboard box printing machine that can solve the above-mentioned problems.

[0005] The purpose of this application is to provide a stacking mechanism for a corrugated cardboard box printing machine, comprising:

[0006] The frame has a roller conveyor mechanism on top for transporting cartons;

[0007] A material blocking mechanism, mounted on the frame, is used to block the conveying of cartons;

[0008] Clamping mechanism, used to clamp the carton after it has been blocked;

[0009] The lifting mechanism includes a housing and lifting components mounted on the housing;

[0010] The lifting component is connected to the clamping mechanism and is used to drive the clamping mechanism to move up and down.

[0011] The stacking mechanism of the corrugated cardboard printing machine described above involves the following steps: during stacking, small stacks of cardboard are transported via a roller conveyor. A blocking mechanism blocks the cardboard, and after blocking, a lifting mechanism is activated, which in turn activates a clamping mechanism to clamp the cardboard. At this time, the lifting mechanism raises the clamping mechanism, thereby raising the cardboard. The next batch of cardboard is then transported and blocked. The lifting mechanism lowers the clamping mechanism and places the clamped cardboard on top of the blocked cardboard. This process is repeated to stack the cardboard. After stacking is complete, the blocking mechanism releases the cardboard, and the cardboard is finally transported to the next processing unit via the roller conveyor.

[0012] During the stacking process, the automatic stacking of cardboard boxes is achieved through the coordinated work of various components. Small stacks of cardboard boxes are transported by a roller conveyor mechanism, blocked by a material stop mechanism, clamped by a gripping mechanism, and moved up and down by a lifting mechanism, allowing the cardboard boxes to be stacked layer by layer in an orderly manner. After stacking is completed, the material stop mechanism is released, and the boxes are sent to the next processing component via the roller conveyor mechanism. The entire process requires no manual intervention, replacing traditional manual paper feeding, avoiding interruptions in manual operation, ensuring continuous paper feeding, and solving the problem of low work efficiency in traditional methods.

[0013] Furthermore, the lifting assembly includes:

[0014] The drive motor is located at the top of the housing;

[0015] The mounting bracket is located inside the housing, and the clamping mechanism is mounted on the frame;

[0016] A connecting bracket is provided on the top of the mounting bracket, and a threaded sleeve is provided on the top;

[0017] The output shaft of the drive motor is equipped with a threaded rod that connects to the threaded sleeve.

[0018] Furthermore, guide sliders are provided on both sides of the mounting bracket, and guide rails adapted to the guide sliders are provided on the side wall of the housing.

[0019] In this application, the lifting mechanism drives a threaded rod to rotate via a drive motor, causing the connecting frame and mounting frame to move up and down, thereby raising and lowering the clamping mechanism. This enables smooth lifting and lowering of the clamping mechanism, ensuring that the clamped cardboard is accurately placed onto the next batch of blocked cardboard, thus ensuring neat stacking. In existing technologies, it is difficult to accurately control the stacking height and alignment during traditional manual stacking; the stable lifting and lowering of the lifting mechanism solves this problem.

[0020] Meanwhile, the guide sliders on both sides of the mounting frame cooperate with the guide rails on the side wall of the housing to limit the movement direction of the mounting frame, preventing the mounting frame from shaking or deviating during lifting and lowering, further ensuring the stability of lifting and lowering, and making the stacking process more reliable.

[0021] Furthermore, the clamping mechanism includes:

[0022] Guide rails are located at the bottom of the mounting bracket;

[0023] Two clamps are provided and symmetrically installed at the bottom of the mounting frame, and each clamp is equipped with a guide frame at the top that is compatible with the guide rail;

[0024] The servo motor is located at the bottom of the mounting bracket, and its output shaft is equipped with a double-ended screw, which is threadedly connected to the guide bracket.

[0025] There are two guide rails, which are installed at an interval at the bottom of the mounting bracket.

[0026] In this application, the clamping mechanism is used to clamp the blocked cardboard. The double-headed screw is driven to rotate by a servo motor, so that the two clamping plates move in opposite directions along the guide rail to achieve clamping and releasing of the cardboard.

[0027] The two clamping plates are installed symmetrically, applying force evenly from both sides to ensure stable clamping and prevent the cardboard boxes from falling or shifting during lifting. In traditional manual handling and stacking, cardboard boxes are prone to tilting due to uneven force; the symmetrical clamping mechanism solves this problem. Furthermore, the cooperation between the guide rail and the guide frame makes the movement of the clamping plates smoother and more stable, avoiding jamming that could affect clamping efficiency.

[0028] Furthermore, the bottom of the clamping plate is provided with clamping teeth, and the end of the clamping teeth near the cardboard is provided with an inclined surface.

[0029] The teeth at the bottom of the clamp increase the contact friction with the cardboard, making the clamp more secure and preventing the cardboard from slipping during movement. At the same time, the inclined surface of the teeth near the cardboard can guide the clamp when it approaches the cardboard, allowing the teeth to make smoother contact with the cardboard and preventing the edges of the teeth from scratching the cardboard.

[0030] Furthermore, the inlet of the clamping plate is also provided with a guide plate, which is inclined.

[0031] The inclined guide plate installed at the clamping plate inlet can guide the carton board to enter the space between the two clamping plates more accurately, reducing the situation where the carton board cannot be accurately clamped due to slight deviation in position, and improving the working reliability of the clamping mechanism.

[0032] Furthermore, the material stopping mechanism includes:

[0033] The base is mounted on the rack.

[0034] The drive cylinder is mounted on the base;

[0035] The baffle includes a plate body and a connecting plate, the connecting plate being connected to the output shaft of the drive cylinder;

[0036] The connecting plate is also equipped with a guide slide rod, and the base is equipped with a guide sleeve that matches the guide slide rod.

[0037] The blocking mechanism obstructs the carton board during transport, stopping it at a designated position to prepare it for clamping by the gripping mechanism. In traditional paper feeding, the placement of the carton board is easily affected by human factors and varies. The blocking mechanism ensures that the blocked carton board is consistently positioned, laying the foundation for neat stacking later. A drive cylinder moves the blocking plate, switching between blocking and releasing. Combined with the guide rod and guide sleeve, this makes the movement of the blocking plate smoother and avoids deviations in the blocking position caused by plate wobbling.

[0038] The beneficial effects of this application are:

[0039] 1. By coordinating various components, the system replaces traditional manual paper feeding, enabling automatic stacking of cardboard boxes. This avoids interruptions in manual operation, ensures continuous paper feeding, and improves work efficiency.

[0040] 2. The material blocking mechanism ensures that the carton boards are in the same position, the clamping mechanism holds them, and the lifting mechanism adjusts their height, making the stacking more neat.

[0041] 3. By installing clamping teeth on the clamping plate, the convenience and stability of clamping can be enhanced. Combined with the inclined surface and guide plate, the carton can be clamped and stacked without damaging it. Attached Figure Description

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0051] The stacking mechanism of the corrugated cardboard box printing machine provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0052] Example 1:

[0053] like Figure 1 As shown, this application embodiment provides a stacking mechanism for a corrugated cardboard box printing machine, including:

[0054] The frame 100 has a roller conveyor mechanism 200 for conveying cartons on its top;

[0055] A material blocking mechanism 300 is mounted on the frame 100 and is used to block the conveyed cartons;

[0056] Clamping mechanism 400 is used to clamp the carton after it has been blocked;

[0057] The lifting mechanism includes a housing 500 and a lifting assembly 600 disposed on the housing 500;

[0058] The lifting component 600 is connected to the clamping mechanism 400 and is used to drive the clamping mechanism to move up and down.

[0059] In some embodiments of this application, such as Figure 1 As shown, in the stacking mechanism of the corrugated cardboard printing machine described above, during stacking, small piles of cardboard are transported by the roller conveyor mechanism 200. The blocking mechanism 300 blocks the cardboard. After blocking, the lifting mechanism starts and drives the clamping mechanism 400 to start, clamping the cardboard. At this time, the lifting mechanism drives the clamping mechanism 400 to rise, thereby driving the cardboard to rise. At this time, the next batch of cardboard is transported and blocked. The lifting mechanism drives the clamping mechanism 400 to fall and places the clamped cardboard on the blocked cardboard. This process is repeated to stack the cardboard. After stacking is completed, the blocking mechanism 300 is released, and finally the cardboard is transported to the next processing part by the roller conveyor mechanism 200.

[0060] During the stacking process, the automatic stacking of cardboard boxes is achieved through the coordinated work of various components. Small stacks of cardboard boxes are transported by the roller conveyor mechanism 200, blocked by the material stop mechanism 300, clamped by the clamping mechanism 400, and moved up and down by the lifting mechanism, allowing the cardboard boxes to be stacked layer by layer in an orderly manner. After stacking is completed, the material stop mechanism 300 is released, and the boxes are sent to the next processing component via the roller conveyor mechanism 200. The entire process requires no manual intervention, replacing the traditional manual paper feeding, avoiding interruptions in manual operation, ensuring the continuity of paper feeding, and solving the problem of low work efficiency in traditional methods.

[0061] Example 2:

[0062] This application provides a stacking mechanism for a corrugated carton printing machine. In addition to the above-mentioned technical features, the stacking mechanism of the corrugated carton printing machine in this application also includes the following technical features.

[0063] As shown in the figure, the lifting assembly 600 includes:

[0064] The drive motor 610 is located on the top of the housing 500;

[0065] Mounting bracket 620 is set inside housing 500, and clamping mechanism 400 is mounted on frame 100;

[0066] A connecting bracket 630 is disposed on the top of the mounting bracket 620, and a threaded sleeve 640 is provided on the top;

[0067] The output shaft of the drive motor 610 is provided with a threaded rod 650 that is connected to the threaded sleeve 640.

[0068] In this embodiment, further: guide sliders 660 are provided on both sides of the mounting bracket 620, and guide rails 670 adapted to the guide sliders 660 are provided on the side wall of the housing 500.

[0069] In this application, the lifting mechanism drives the threaded rod 650 to rotate via the drive motor 610, causing the connecting frame 630 and the mounting frame 620 to move up and down, thereby driving the clamping mechanism 400 to rise and fall. This enables the clamping mechanism 400 to rise and fall smoothly, ensuring that the clamped cardboard is accurately placed onto the next batch of blocked cardboard, thus ensuring the neatness of the stack. In the prior art, it is difficult to accurately control the stacking height and alignment during traditional manual stacking; the stable lifting mechanism solves this problem.

[0070] Meanwhile, the guide sliders 660 on both sides of the mounting bracket 620 cooperate with the guide rails 670 on the side wall of the housing 500 to limit the movement direction of the mounting bracket 620, prevent the mounting bracket 620 from shaking or deviating during the lifting process, further ensure the stability of the lifting and making the stacking process more reliable.

[0071] Example 3:

[0072] This application provides a stacking mechanism for a corrugated carton printing machine. In addition to the above-mentioned technical features, the stacking mechanism of the corrugated carton printing machine in this application also includes the following technical features.

[0073] As shown in the figure, the clamping mechanism 400 includes:

[0074] Guide rail 410 is located at the bottom of mounting bracket 620;

[0075] Two clamping plates 420 are provided and symmetrically installed at the bottom of the mounting bracket 620. Each clamping plate 420 has a guide bracket 430 adapted to the guide rail 410 at its top.

[0076] The servo motor 440 is located at the bottom of the mounting bracket 620, and its output shaft is equipped with a double-ended screw, which is threadedly connected to the guide bracket 430.

[0077] There are two guide rails 410, which are installed at intervals on the bottom of the mounting bracket 620.

[0078] In this embodiment of the application, the clamping mechanism 400 is used to clamp the blocked cardboard board. The servo motor 440 drives the double-headed screw to rotate, so that the two clamping plates 420 move in opposite directions along the guide rail 410 to achieve clamping and releasing of the cardboard board.

[0079] The two clamping plates 420 are symmetrically installed, applying force evenly from both sides to ensure stable clamping and prevent the cardboard boxes from falling or shifting during lifting. In traditional manual handling and stacking, cardboard boxes are prone to tilting due to uneven force; the symmetrical clamping of the clamping mechanism 400 solves this problem. Furthermore, the cooperation between the guide rail 410 and the guide frame 430 makes the movement of the clamping plates 420 smoother and more stable, avoiding jamming that could affect clamping efficiency.

[0080] Furthermore, the bottom of the clamping plate 420 is provided with clamping teeth 421, and the end of the clamping teeth 421 near the cardboard is provided with an inclined surface 422.

[0081] The clamping teeth 421 at the bottom of the board increase the contact friction with the cardboard, making the clamping more secure and preventing the cardboard from slipping during movement. At the same time, the end of the clamping teeth 421 near the cardboard is inclined surface 422, which can guide the clamping plate 420 when it approaches the cardboard, allowing the clamping teeth 421 to contact the cardboard more smoothly and preventing the edges of the clamping teeth 421 from scratching the cardboard.

[0082] Furthermore, the entrance of the clamping plate 420 is also provided with a guide plate 423, which is inclined.

[0083] The inclined guide plate 423 installed at the entrance of the clamping plate 420 can guide the carton board to enter the two clamping plates 420 more accurately, reducing the situation where the carton board cannot be accurately clamped due to slight deviation in position, and improving the working reliability of the clamping mechanism 400.

[0090] The connecting plate 340 is also provided with a guide slide rod 350, and the base 310 is provided with a guide sleeve 360 ​​that is adapted to the guide slide rod 350.

[0091] In this embodiment, the blocking mechanism 300 blocks the carton board during transport, stopping it at a designated position to prepare for clamping by the clamping mechanism 400. In traditional paper feeding, the placement of the carton board is easily affected by human factors and is inconsistent. The blocking mechanism 300 ensures that the blocked carton board is consistently positioned each time, laying the foundation for neat stacking later. The drive cylinder 320 moves the baffle, switching between blocking and releasing. Combined with the guide slide rod 350 and guide sleeve 360, this makes the movement of the baffle smoother and avoids deviations in the blocking position caused by baffle wobbling.
