Description

Technical Field

[0001] This utility model belongs to the field of paperboard machinery pressure roller technology, and in particular relates to a corrugated paper cutting pressure roller device. Background Technology

[0002] After production, corrugated cardboard needs to undergo processing such as cutting and creasing to form carton blanks of specific specifications. In this process, the corrugated cardboard cutting device is a key piece of equipment. Its function is to accurately cut and creasing the continuously conveyed corrugated cardboard. This device usually includes a pair of relatively rotating pressure rollers, one of which is a cutting roller equipped with a cutter, and the other is a pressure roller that cooperates with the cutting. Its core function is to provide stable and uniform support force for cutting, ensuring that the cutter can fully contact the corrugated cardboard and complete a clean and neat cut, while preventing the cardboard from tearing or deforming during the cutting process. In order to adapt to the cutting needs of different widths, pressure roller devices with diameter adjustment functions have emerged.

[0003] Existing corrugated paper cutting roller devices still have some problems during use. For example, after adjusting the diameter, a physical gap will be generated between the fixed base roller surface and the movable adjustment roller surface, causing the overall outline of the roller to no longer be a complete circle. When cutting, this recessed area cannot provide effective support for the corrugated cardboard, resulting in quality problems such as incomplete cutting and unclear creases, which seriously affect production efficiency and yield.

[0004] To address this issue, we provide a corrugated paper cutting roller device. Utility Model Content

[0005] The purpose of this utility model is to provide a corrugated paper cutting pressure roller device. By setting up an extension mechanism, it solves the problem in the prior art that a physical gap will occur between the fixed base roller surface and the movable adjustment roller surface after the diameter is adjusted in the corrugated paper cutting pressure roller device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a corrugated paper cutting pressure roller device, comprising a fixed roller surface, an adjusting roller surface disposed inside the fixed roller surface, an expansion mechanism disposed inside the fixed roller surface, the expansion mechanism comprising a pushing component disposed inside the fixed roller surface, an adjusting block fixedly connected to one side of the adjusting roller surface, a resetting component disposed inside the fixed roller surface, a limiting component disposed inside the fixed roller surface, a filling component disposed on the outer surface of the fixed roller surface, and a rubber sleeve disposed outside the adjusting roller surface.

[0008] The present invention is further configured such that the pushing assembly includes a screw disposed inside the fixed roller surface, a threaded sleeve threadedly connected to the surface of the screw, and a pushing block fixedly connected to one side of the threaded sleeve.

[0009] The present invention is further configured such that an inlet and outlet through groove adapted to the adjusting roller surface is provided inside the fixed roller surface, and a support plate is fixedly connected inside the fixed roller surface.

[0010] The present invention is further configured such that the reset assembly includes a reset groove formed inside the fixed roller surface, a reset rod fixedly connected inside the reset groove, a spring sleeved on the surface of the reset rod, and a reset block fixedly connected to one end of the spring.

[0011] The present invention is further configured such that the limiting component includes a limiting block disposed inside the fixed roller surface, and a limiting rod fixedly connected to one side of the limiting block.

[0012] The present invention is further configured such that the filling component includes a filling airbag disposed on the surface of the fixed roller, mounting blocks fixedly connected to both sides of the filling airbag, and a fixing ring threadedly connected to both sides of the fixed roller, wherein the surface of the fixed roller is provided with a limiting groove adapted to the mounting block.

[0013] The present invention is further configured such that hollow rods are fixedly connected to both sides of the fixed roller surface, and the hollow rods are movably connected to the external cutting machine through bearings. A rotary joint is fixedly connected inside the left hollow rod, one end of the rotary joint is connected to an external air pipe, and the other end of the rotary joint is connected to a diverter pipe.

[0014] This invention has the following advantages: by rotating the screw, the screw sleeve and the push block move linearly, which in turn pushes the adjusting block to make the adjusting roller surface extend from the fixed roller surface. During this process, the reset component stores energy, and the limiting component ensures stable movement. After the adjustment is completed, the filling airbag inflates and expands, effectively filling the gap caused by the adjustment and forming continuous support for the rubber sleeve. This allows the pressure roller to maintain a complete circular outline after the diameter is adjusted, effectively solving the problem of uneven support caused by the gap in traditional adjustable pressure rollers and improving the cutting quality of corrugated cardboard.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0025] Please see Figures 1-6 This utility model is a corrugated paper cutting pressure roller device, including a fixed roller surface 1, an adjusting roller surface 2 inside the fixed roller surface 1, an expansion mechanism 3 inside the fixed roller surface 1, the expansion mechanism 3 including a pushing component 31 inside the fixed roller surface 1, an adjusting block 32 fixedly connected to one side of the adjusting roller surface 2, a reset component 33 inside the fixed roller surface 1, a limiting component 34 inside the fixed roller surface 1, a filling component 35 on the outer surface of the fixed roller surface 1, and a rubber sleeve 36 on the outside of the adjusting roller surface 2.

[0026] As a preferred embodiment of the above, the function of the extension mechanism 3 is to realize the flexible adjustment of the diameter of the pressure roller, and to ensure that the roller surface still maintains a complete circular outline after adjustment through the filling component 35. The external motor drives the screw 311 to rotate, which drives the two screw sleeves 312 with opposite directions of rotation on its surface to move towards or away from each other. The screw sleeves 312 transmit linear motion to the adjustment block 32 fixed to the adjustment roller surface 2 through the pushing block 313, thereby forcing the adjustment roller surface 2 to extend outward or retract inward from the inlet and outlet groove of the fixed roller surface 1. When the adjustment roller surface 2 extends outward, the spring 332 of the reset component 33 is compressed and stored to provide power for reset. At the same time, the limiting component 34 ensures that the screw sleeves 312 only move in a straight line and do not rotate. When the adjustment roller surface 2 extends to the predetermined position, the filling air bag 351 located between them inflates and expands, effectively filling the physical gap caused by adjustment, forming uniform support for the external rubber sleeve 36, so that the pressure roller always maintains a complete outline of approximately circular shape under the working diameter. Example

[0027] Please see Figures 1-6Based on Embodiment 1, the pushing assembly 31 includes a screw 311 disposed inside the fixed roller surface 1, a threaded sleeve 312 threadedly connected to the surface of the screw 311, and a pushing block 313 fixedly connected to one side of the threaded sleeve 312. The threads on the surfaces of the screw 311 are opposite in direction. There are two threaded sleeves 312 and two pushing blocks 313. The pushing block 313 has a movable through hole adapted to the screw 311 inside. The fixed roller surface 1 has an inlet / outlet through groove adapted to the adjusting roller surface 2. There are ten adjusting roller surfaces 2 and ten adjusting blocks 32. All ten adjusting rollers are located inside the inlet / outlet through grooves. The adjusting rollers are designed with uniformly spaced circular spacing. A support plate 4 is fixedly connected inside the fixed roller surface 1. The screw 311 is movably connected to the support plate 4 through a bearing. The reset assembly 33 includes a reset groove opened inside the fixed roller surface 1, a reset rod 331 fixedly connected inside the reset groove, a spring 332 sleeved on the surface of the reset rod 331, and a reset block 333 fixedly connected to one end of the spring 332. One side of the reset block 333 is fixedly connected to the adjusting roller surface 2. A reset through hole is opened inside the reset block 333, and the reset rod 331 is located inside the reset through hole. The limiting assembly 34 includes a fixed... The fixed roller surface 1 has a limiting block 341 inside and a limiting rod 342 fixedly connected to one side of the limiting block 341. The support plate 4 has a limiting through hole inside, and the limiting rod 342 is located inside the limiting through hole. One side of the limiting block 341 is fixedly connected to the threaded sleeve 312. The filling assembly 35 includes a filling airbag 351 disposed on the surface of the fixed roller surface 1, mounting blocks 352 fixedly connected to both sides of the filling airbag 351, and a fixing ring 353 threadedly connected to both sides of the fixed roller surface 1. The surface of the mounting block 352 is provided with mounting threads adapted to the fixing ring 353. The rubber sleeve 36 is fixedly connected to the fixing ring. On the surface of the fixed roller surface 1, a limiting groove 5 adapted to the mounting block 352 is provided. The filling airbag 351 is set between the two adjusting roller surfaces 2. Hollow rods 6 are fixedly connected to both sides of the fixed roller surface 1. The hollow rods 6 are movably connected to the external cutting machine through bearings. A rotary joint 7 is fixedly connected inside the left hollow rod 6. One end of the rotary joint 7 is connected to the external air pipe, and the other end of the rotary joint 7 is connected to the diverter pipe 8. The other end of the diverter pipe 8 is connected to the filling airbag 351. One end of the screw 311 extends to the outside of the right hollow rod 6 and is fixedly connected to the motor output end in the external cutting machine.

[0028] As a preferred embodiment of the above: With the push assembly 31, an external motor drives the screw 311 to rotate. The screw 311 drives the screw sleeve 312 and the push block 313 to move. After the push block 313 contacts the adjusting block 32, it pushes the adjusting roller surface 2, which is fixed to the adjusting block 32, to extend outward, thereby expanding the externally fitted rubber sleeve 36. The in-and-out through groove provides space for the outward expansion and repositioning of the adjusting roller surface 2. The support plate 4 provides support for the screw 311. The repositioning assembly 33 compresses the spring 332 during the outward extension of the adjusting roller surface 2. When the adjusting roller surface 2 needs to reposition inward, the screw sleeve 312 drives the push block 313 to reposition. After the adjusting block 32 loses its pushing force, the spring 332 repositions the adjusting roller surface 2 back into the in-and-out groove. The limiting assembly 34 provides a limit for the screw sleeve 312, preventing it from rotating during movement. The filling assembly 35 fills the airbag 351 on both sides. The mounting block 352 is placed into the limiting groove 5 of the fixed roller surface 1, and then the fixing ring 353 is tightened to make the fixing ring 353 threadedly connected to the fixed roller surface 1 and the mounting block 352, thereby completing the fixing of the filling airbag 351. The threaded fixing method facilitates the maintenance of the filling airbag 351. Multiple filling airbags 351 are set between two adjusting roller surfaces 2. After the adjusting roller surface 2 extends outward, the filling airbag 351 is inflated, causing it to expand and provide effective support for the rubber sleeve 36 sleeved on the outside, making the rubber sleeve 36 more circular. This effectively fills the gap between the fixed roller surface 1 and the adjusting roller surface 2 after the diameter is adjusted, ensuring the continuity of the shape and the stability of the structure of the rubber sleeve 36. The hollow rod 6 provides support for the installation of the fixed roller surface 1. The rotary joint 7 and the diverter 8 allow gas to be delivered to the filling airbag 351 when the fixed roller surface 1 rotates, inflating or deflating the filling airbag 351, thereby adjusting the supporting pressure on the rubber sleeve 36.

[0029] The working principle of this utility model is as follows: When the diameter of the pressure roller needs to be adjusted, the external motor starts and drives the screw 311 to rotate. Under the constraint of the limiting component 34, the two screw sleeves 312 with opposite directions of rotation move in a straight line along the axis of the screw 311, thereby driving the pushing block 313 to move synchronously. The pushing block 313 directly acts on the adjusting block 32 which is fixedly connected to the adjusting roller surface 2, and transmits the force to the adjusting roller surface 2, so that it stably extends outward or retracts inward from the inlet and outlet groove of the fixed roller surface 1. During the outward extension of the adjusting roller surface 2, the spring 332 of the reset component 33 is compressed and stores energy, preparing for the subsequent reset action.

[0030] After the diameter adjustment of the adjusting roller surface 2 is completed and the position is fixed, the filling component 35 located between the adjacent adjusting roller surfaces 2 starts to work. The external air source inflates the filling air bag 351 through the rotary joint 7 and the diverter pipe 8, causing it to expand. The bulging filling air bag 351 effectively fills the physical gap between the fixed roller surface 1 and the adjusting roller surface 2 caused by the movement of the adjusting roller surface 2, and forms a uniform and continuous support for the rubber sleeve 36 sleeved on the entire roller body.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
