Description

Technical Field

[0001] This application relates to the field of creasing roller technology, and in particular to a carton creasing roller assembly. Background Technology

[0002] In the carton production process, the creasing roller assembly is used to press crease lines into cardboard or corrugated cardboard for subsequent folding and shaping.

[0003] Traditional crease roller assemblies typically consist of a single pressure roller placement table. During operation, the operator places the cardboard on the placement table, allowing the cardboard to pass between the two. The pressure roller surface has annular raised crease teeth. Under mechanical pressure, the crease teeth locally indent the cardboard to form continuous crease lines, while maintaining the integrity of the cardboard fibers to facilitate subsequent folding.

[0004] In actual operation, existing creasing devices are prone to lateral displacement or angular deflection of the cardboard due to the need for positioning. This positional deviation causes the creasing rollers to misalign with the intended creasing position, resulting in the creasing trajectory deviating from the design path and causing quality issues such as creasing misalignment. Utility Model Content

[0005] To address the issue that traditional creasing rollers have limited adjustment range in creasing depth and width, making them difficult to adapt to different cardboard thicknesses and leading to either shallow creasing resulting in unclear creases or excessively deep creasing causing cardboard breakage, this application provides a carton creasing roller assembly.

[0006] The cardboard box creasing wheel assembly provided in this application adopts the following technical solution:

[0007] A carton creasing wheel assembly includes a workbench, a support frame fixedly connected to the top of the workbench, a creasing wheel body disposed inside the support frame, a dual-axis motor fixedly connected to the bottom of the workbench, transmission rods fixedly connected to the output ends on both sides of the dual-axis motor, a lead screw fixedly connected to one end of the transmission rod, a bushing threaded onto the surface of the lead screw, a movable plate fixedly connected to the outer wall of the bushing, a limit plate fixedly connected to one end of the movable plate, and a guide plate fixedly connected to one side of the limit plate.

[0008] Preferably, the bottom of the workbench is provided with limiting grooves on both sides, and limiting blocks are slidably connected inside the limiting grooves. The bottom of the limiting blocks is fixedly connected to the movable plate.

[0009] Preferably, an extension plate is fixedly connected to the back of the guide plate, and a spring is fixedly connected between the extension plate and the limiting plate.

[0010] Preferably, an electric push rod is fixedly connected to the bottom of the support frame, a support plate is fixedly connected to the bottom of the electric push rod, limit blocks are fixedly connected to both sides, a moving groove is provided on both sides of the inner sidewall of the support frame, a limit block is slidably connected to the inner wall of the moving groove, and the pressure wheel body is rotatably connected to the support plate.

[0011] Preferably, a connecting block is rotatably connected to the surface of the transmission rod, the top of the connecting block is fixedly connected to the worktable, and a bearing is provided inside the connecting block.

[0012] Preferably, the guide surface of the guide plate is inclined or arc-shaped, and the number of springs is at least two, symmetrically distributed on both sides of the extension plate.

[0013] Preferably, the pressure wheel body is made of high-strength alloy steel, and the contact surface of the pressure wheel body is provided with annular pressure protrusions.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. The dual-axis motor drives the transmission rod, lead screw and bushing to drive the limiting plate and guide plate on the movable plate to symmetrically limit the cardboard from both sides, preventing its lateral displacement or angular deflection, and can limit cardboard of different widths to improve versatility.

[0016] 2. The height of the creasing roller can be adjusted by moving the push rod to adapt to the creasing requirements of cartons of different thicknesses and specifications, thus improving the versatility and flexibility of the components. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Reference Figure 1-4 This utility model provides a carton creasing wheel assembly, including a workbench 1, a support frame 101 fixedly connected to the top of the workbench 1, a creasing wheel body 102 inside the support frame 101, a dual-axis motor 2 fixedly connected to the bottom of the workbench 1, transmission rods 201 fixedly connected to the output ends on both sides of the dual-axis motor 2, a lead screw 202 fixedly connected to one end of the transmission rod 201, a bushing 203 threadedly connected to the surface of the lead screw 202, a movable plate 204 fixedly connected to the outer wall of the bushing 203, a limit plate 3 fixedly connected to one end of the movable plate 204, and a guide plate 301 fixedly connected to one side of the limit plate 3.

[0024] When creasing the cardboard is required, to prevent the cardboard from skewing, the dual-axis motor 2 is started, and its output ends on both sides drive the transmission rod 201 to rotate. The lead screw 202 connected to one end of the transmission rod 201 rotates accordingly. Since the bushing 203 is threadedly connected to the lead screw 202, and a movable plate 204 is fixed to the outer wall of the bushing 203, the bushing 203 moves linearly along the axis of the lead screw 202 during rotation, thereby driving the movable plate 204 to move. One end of the movable plate 204 is connected to a limiting plate 3, and a guide plate 301 is fixed to one side of the limiting plate 3. When the cardboard is placed on the workbench 1 to enter the creasing area, the guide plate 301 first contacts the edge of the cardboard, providing initial guidance. As the movable plate 204 moves, the limiting plate 3 gradually approaches the cardboard, limiting it from both sides to prevent lateral displacement.

[0025] The dual-axis motor 2 drives the transmission rod 201, lead screw 202 and bushing 203, which in turn drives the limiting plate 3 and guide plate 301 on the movable plate 204 to symmetrically limit the cardboard from both sides, preventing its lateral displacement or angular deflection. It can also limit cardboard of different widths to improve versatility.

[0026] In a preferred embodiment, the bottom of the workbench 1 is provided with limiting grooves 4 on both sides, and limiting blocks 401 are slidably connected inside the limiting grooves 4. The bottom of the limiting blocks 401 is fixedly connected to the movable plate 204.

[0027] The limiting block 401 fixed at the bottom of the movable plate 204 will slide within the limiting grooves 4 on both sides of the bottom of the worktable 1. The limiting grooves 4 guide and limit the movement of the limiting block 401, so that the movable plate 204 can only move in a straight line along the direction of the limiting grooves 4, thereby ensuring the accurate movement direction of the limiting plate 3 and the guide plate 301.

[0028] In a preferred embodiment, an extension plate 302 is fixedly connected to the back of the guide plate 301, and a spring is fixedly connected between the extension plate 302 and the limiting plate 3.

[0029] When the carton enters the creasing position under the guidance of the guide plate 301, the dimensional deviation of the carton may generate a certain impact force on the guide plate 301, allowing the guide plate 301 to move within a certain range and buffer the external force. When the external force disappears, the spring will return to its original state, causing the guide plate 301 to return to the preset position. The guide plate 301 and the extension plate 302 are made of soft materials such as engineering plastics.

[0030] In a preferred embodiment, an electric push rod 5 is fixedly connected to the bottom of the support frame 101, a support plate 501 is fixedly connected to the bottom of the electric push rod 5, and limit blocks 502 are fixedly connected to both sides of the electric push rod 5. Movable grooves 503 are provided on both sides of the inner wall of the support frame 101, and the limit blocks 502 are slidably connected to the inner wall of the movable grooves 503. The pressure wheel body 102 is rotatably connected to the support plate 501.

[0031] When the height of the crease roller body 102 needs to be adjusted according to different carton sizes, the electric push rod 5 is activated. The electric push rod 5 is fixed to the bottom of the support frame 101, and the support plate 501 connected to its bottom moves up and down as the electric push rod 5 extends and retracts. The limiting blocks 502 fixed on both sides of the support plate 501 slide within the moving grooves 503 on both sides of the inner wall of the support frame 101, serving as guides and limits, ensuring that the support plate 501 can only move in a straight line up and down. The crease roller body 102 is rotatably connected to the support plate 501, and therefore moves up and down as the support plate 501 moves, thereby achieving the adjustment of the height of the crease roller body 102.

[0032] The electric push rod 5 can adjust the height of the creasing wheel body 102 to adapt to the creasing requirements of cartons of different thicknesses and specifications, thus improving the versatility and flexibility of the components.

[0033] In a preferred embodiment, a connecting block 2011 is rotatably connected to the surface of the transmission rod 201, the top of the connecting block 2011 is fixedly connected to the workbench 1, and a bearing is provided inside the connecting block 2011.

[0034] When the dual-axis motor 2 drives the transmission rod 201 to rotate, the bearing inside the connecting block 2011 reduces rotational friction, making the transmission smoother. The connecting block 2011 stably fixes the transmission rod 201 on the worktable 1, preventing shaking during transmission.

[0035] In a preferred embodiment, the guide surface of the guide plate 301 is inclined or arc-shaped, and the number of springs is at least two, symmetrically distributed on both sides of the extension plate 302.

[0036] The guide surface of the guide plate 301 is designed with an inclined or curved structure. When the carton enters the creasing position under the guidance of the guide plate 301, the inclined or curved structure can better adapt to the feeding direction of the carton, allowing the carton to reach the creasing roller body 102 more smoothly. The inclined or curved guide surface can improve the smoothness of carton feeding.

[0037] In a preferred embodiment, the pressure roller body 102 is made of high-strength alloy steel, and the contact surface of the pressure roller body 102 is provided with annular pressure protrusions.

[0038] The high-strength alloy steel material ensures that the pressure roller body 102 is not easily worn or deformed during long-term use, and the annular pressure protrusions are clearer.

[0039] The foregoing description of an exemplary embodiment of a carton creasing roller assembly provided by this disclosure refers to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
