Description

Technical Field

[0001] This utility model relates to the field of paper alignment technology, and in particular to an adjustable paper cutter alignment mechanism. Background Technology

[0002] In the paper and packaging paperboard production process, the paper cutter is the main equipment for cutting paper. During the paper cutting process, the paper needs to be aligned to ensure that the edges of the cut paper are neat and precise. Therefore, an adjustable paper cutter alignment mechanism is used.

[0003] To address this, patent CN218699328U discloses an alignment mechanism for a paper cutter that facilitates cutting. The mechanism includes an operating table and sliders. Two sliders are slidably connected inside the operating table, and these sliders are fixedly connected to the outer wall of a base plate. The base plate is slidably connected to the surface of the operating table. An alignment mechanism is installed inside the base plate, and a frame is fixedly attached to the surface of the operating table. Through the cooperation of a bracket, a first hydraulic cylinder, a pressure block, a spring, a support rod, and a connecting rod, the first hydraulic cylinder drives the bracket to slide, causing the inner walls of the two side brackets to adhere to the paper. Releasing the connecting rod allows the springs to drive the pressure block downwards under elastic force, pressing down on the upper surface of the paper to prevent it from becoming disordered during movement. The two side brackets replace manual alignment, preventing accidents. The cooperation between the bracket and the pressure block makes paper alignment easier during cutting.

[0004] Although the paper cutter alignment mechanism mentioned above makes it easier to align the paper during cutting by cooperating with the support and pressure block, it is inconvenient to position and align one end of the paper, resulting in inconsistent paper lengths and low applicability. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable paper cutter alignment mechanism to solve the problem of inconvenient positioning in existing adjustable paper cutter alignment mechanisms.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable paper cutter alignment mechanism, including a worktable and a support;

[0007] A support is fixed to the top of the workbench, a cutting assembly is provided on the top of the support, and an alignment structure is fixed to the top of the workbench on one side of the support.

[0008] A movable structure is fixed on one side of the top of the workbench;

[0009] A positioning structure is provided on one side of the top of the worktable. The positioning structure includes an internal cavity, a second threaded rod, a second servo motor, a moving block, a positioning plate, a slider, and a slide groove. The internal cavity is located on one side of the top of the worktable. The second threaded rod is installed inside the internal cavity. A second servo motor is installed on the outer wall of the worktable at one end of the second threaded rod. A moving block is threaded to the outer side of the second threaded rod. The top of the moving block extends to the outside of the worktable and is fixed with a positioning plate. Slide grooves are provided on the top of the worktable on both sides of the internal cavity. A slider is installed inside each slide groove.

[0010] When using this device, the positioning structure facilitates alignment, thereby improving the applicability of the adjustable paper cutter alignment mechanism; the moving structure facilitates auxiliary alignment, thereby improving the convenience of use; and the alignment structure facilitates left and right alignment, thereby improving the stability of use.

[0011] Preferably, the movable structure includes a vertical plate, a first electric push rod, a movable plate, and guide rods. The vertical plate is fixed to one side of the top of the worktable. The first electric push rod passes through the interior of the vertical plate, and one end of the first electric push rod is fixed to the movable plate. Guide rods pass through the interior of the vertical plates on both sides of the first electric push rod. When the first electric push rod is activated, it moves the movable plate, which in turn moves the guide rods within the vertical plate. The guide rods enhance the stability of the movable plate during movement.

[0012] Preferably, the guide rod and the vertical plate form a sliding structure, and one end of the guide rod is fixedly connected to one side of the movable plate. After moving, the movable plate abuts against the side of the paper away from the positioning plate, and under the action of the movable plate and the positioning plate, the front and back of the paper are aligned.

[0013] Preferably, the cutting assembly includes a second electric push rod, a slide rod, a fixing plate, a fixing seat, and a cutting blade. The second electric push rod extends through the top of the bracket, and a fixing plate is fixed to the bottom end of the second electric push rod. The cutting blade is fixed to the bottom end of the fixing plate, and a fixing seat is fixed to the bottom of the cutting blade. Slide rods extend through the interior of the bracket on both sides of the second electric push rod. When the second electric push rod is activated, it moves the fixing plate, which in turn moves the slide rods within the bracket.

[0014] Preferably, the slide rod and the bracket form a sliding structure, with the bottom end of the slide rod fixedly connected to the top end of the fixed plate, and a knife groove provided on the top of the worktable below the fixed seat. The slide rod enhances the stability of the fixed plate during movement, and the fixed plate, through the cutting blade, drives the fixed seat to cut the paper.

[0015] Preferably, the alignment structure includes a fixed frame, a first threaded rod, a movable groove, a movable block, a movable seat, a first servo motor, an alignment plate, a support plate, a threaded column, a pressure plate, a guide groove, and a handle. The fixed frame is fixed to the top of the workbench. The top of the fixed frame is provided with a first threaded rod. A first servo motor is installed on the outer wall of the fixed frame at one end of the first threaded rod. Movable seats are threaded to the outer sides of both ends of the first threaded rod. Movable blocks are fixed to the top of each movable seat. Movable grooves are opened inside the fixed frame at the top of each movable block. Alignment plates are fixed to the bottom of each movable seat. Support plates are fixed to one side of each alignment plate. Threaded columns penetrate the interior of each support plate. Handles are fixed to the top of each threaded column. Pressure plates are rotatably connected to the bottom of each threaded column. Guide grooves are opened on one side of the bottom of each alignment plate. The first servo motor is started, which drives the first threaded rod to rotate. Since the threads at both ends of the first threaded rod are in opposite directions, the first threaded rod drives the moving seats at both ends to move in opposite directions. The moving seats drive the movable blocks to move inside the movable slots. Under the action of the movable blocks, the moving seats are prevented from rotating with the first threaded rod. The moving seats drive the alignment plate to move. Under the action of the alignment plate, the paper of different widths can be aligned left and right.

[0016] Preferably, one end of the first threaded rod extends to the outside of the fixed frame and is fixedly connected to the output end of the first servo motor. The threads at both ends of the first threaded rod are in opposite directions. The movable block and the fixed frame form a sliding structure through the movable groove. The threaded column and the support plate are designed with a threaded connection. The pressure plate and the alignment plate form a sliding structure through the guide groove. Rotating the handle causes the threaded column to rotate inside the support plate. The threaded column causes the pressure plate to move inside the guide groove. Under the action of the guide groove, the stability of the pressure plate during movement is enhanced. After moving, the pressure plate presses on the top of the paper to limit the paper of different thicknesses.

[0017] Preferably, one end of the second threaded rod extends to the outside of the worktable and is fixedly connected to the output end of the second servo motor. The top end of the slider extends to the outside of the worktable and is fixedly connected to the bottom end of the positioning plate. The slider and the worktable form a sliding structure through a groove. Paper is placed on the top of the worktable, with one end of the paper abutting against one side of the positioning plate. Under the action of the positioning plate, the paper is easily positioned. The second servo motor is started, driving the second threaded rod to rotate inside the built-in cavity. The second threaded rod drives the moving block to move, and the moving block, through the positioning plate, drives the slider to move inside the groove. Under the action of the slider, the stability of the positioning plate during movement is enhanced, facilitating the positioning of papers of different lengths.

[0018] The adjustable paper cutter alignment mechanism provided by this utility model has the following advantages:

[0019] By setting up a positioning structure, the paper is placed on the top of the worktable, so that one end of the paper abuts against one side of the positioning plate. Under the action of the positioning plate, the paper is easily positioned. The second servo motor is started, and the second servo motor drives the second threaded rod to rotate inside the built-in cavity. The second threaded rod drives the moving block to move. The moving block drives the slider to move inside the slide groove through the positioning plate. Under the action of the slider, the stability of the positioning plate during movement is enhanced, so as to position paper of different lengths. This realizes the function of easy alignment of the device, thereby improving the applicability of the adjustable paper cutter alignment mechanism in use.

[0020] By setting up a movable structure, the first electric push rod is activated, which drives the movable plate to move. The movable plate drives the guide rod to move inside the vertical plate. Under the action of the guide rod, the stability of the movable plate during movement is enhanced. After moving, the movable plate abuts against the side of the paper away from the positioning plate. Under the action of the movable plate and the positioning plate, the front and back of the paper are aligned, realizing the function of the device to facilitate alignment, thereby improving the convenience of the adjustable paper cutter alignment mechanism in use.

[0021] By incorporating an alignment structure, the first servo motor is activated, driving the first threaded rod to rotate. Since the threads at both ends of the first threaded rod are in opposite directions, the first threaded rod drives the moving seats at both ends to move in opposite directions. The moving seats drive the movable blocks to move within the movable grooves. Under the action of the movable blocks, the moving seats are prevented from rotating along with the first threaded rod. The moving seats drive the alignment plate to move, allowing for left-right alignment of papers of different widths. Rotating the handle causes the threaded column to rotate within the support plate. The threaded column drives the pressure plate to move within the guide grooves. The guide grooves enhance the stability of the pressure plate during movement. The moved pressure plate presses against the top of the paper, limiting the movement of papers of different thicknesses. This achieves the function of easy left-right alignment, thereby improving the stability of the adjustable paper cutter alignment mechanism during use. Attached Figure Description
