Description

Technical Field

[0001] This utility model relates to the field of slitting blade adjustment mechanism, specifically to a slitting blade adjustment mechanism for anti-counterfeiting labels. Background Technology

[0002] Many products require anti-counterfeiting labels after being boxed. Anti-counterfeiting labels are usually printed in rolls with multiple columns, such as four columns, in the width direction. When used, the roll of labels needs to be separated. After printing, anti-counterfeiting labels are usually cut by a label slitting machine. Slitting involves cutting the large-format label paper into smaller formats using a cutter to facilitate subsequent storage and use.

[0003] In existing technologies, anti-counterfeiting label slitting machines typically use a fixed blade structure, meaning that the distance between each blade is preset at the factory. When cutting anti-counterfeiting labels of different widths, operators need to manually replace the entire blade assembly or adjust the equipment structure, which is time-consuming, labor-intensive, and prone to causing excessive downtime, thus reducing production efficiency and making it less adaptable.

[0004] Therefore, it is necessary to invent a cutting blade adjustment mechanism for anti-counterfeiting labels to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a slitting blade adjustment mechanism for anti-counterfeiting labels. By setting an adjustment component and a linkage component, rotating the knob can change the spacing between multiple blades while keeping the spacing equal. This solves the problem in the prior art where the slitting blades are connected in a fixed manner, making it inconvenient to flexibly adjust the distance between them.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slitting blade adjustment mechanism for anti-counterfeiting labels, disposed above the blade, including...

[0007] An adjustment component is used to adjust the position of the blade. The adjustment component includes a housing and a movable block. The movable block is connected to the blade via a fixing component. The housing is a cuboid with an opening at the bottom. A screw is rotatably connected to the inner wall of the housing. A knob is fixedly connected to the right side of the screw. A threaded sleeve is threadedly connected to the outer wall of the screw. The number of movable blocks is set to multiple. The outer wall of the threaded sleeve is fixedly connected to the inner wall of the leftmost movable block. Except for the leftmost movable block, the remaining movable blocks have no contact with the screw.

[0008] A linkage assembly, used to adjust the blade spacing, is located on the top of the moving block. The linkage assembly includes a first connecting rod and a pin. The number of first connecting rods is set to multiple, with their ends hinged to each other. The middle part of the first connecting rod is hinged to the top of the moving block, and the multiple first connecting rods form a fork shape with their ends connected. The right end of the rightmost first connecting rod is hinged to a second connecting rod. The inner wall of the end of the second connecting rod away from the first connecting rod is rotatably connected to the outer wall of the pin. The bottom of the pin is fixedly connected to the top of the rightmost moving block, and the top of the pin is fixedly connected to the top of the inner wall of the outer shell. The left end of the leftmost first connecting rod is hinged to a third connecting rod. The end of the third connecting rod away from the first connecting rod is hinged to the top of the leftmost moving block.

[0009] Preferably, the circumferential surface of the knob is provided with anti-slip texture, and the central axis of the knob coincides with the central axis of the screw.

[0010] Preferably, the adjustment assembly further includes a guide rod, which is fixedly connected to the inner wall of the housing, and the outer wall of the guide rod is slidably connected to the inner wall of the moving block.

[0011] Preferably, the number of guide rods is set to two sets, and the two sets of guide rods and screws are on the same horizontal plane and parallel to each other.

[0012] Preferably, the lengths of the second link and the third link are equal, and the length of the first link is twice the length of the second link.

[0013] Preferably, the fixing component includes a protrusion fixedly connected to the top of the blade, and the bottom of the movable block is provided with a groove, the protrusion being inserted into the inner wall of the groove, and the protrusion being detachably connected to the movable block by a fixing bolt.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention features an adjustment assembly. By rotating a screw with a knob, the leftmost moving block moves. Through the hinged transmission of multiple connecting rods in the linkage assembly, and the coordinated action of connecting rods two and three, the other moving blocks move synchronously, and the spacing between the multiple moving blocks remains equal. As the multiple moving blocks move, the blades at the bottom of the moving blocks follow the movement, enabling the multiple blades to expand or contract at equal intervals. This stabilizes the blade spacing, improves the uniformity of the anti-counterfeiting label slices, meets the slitting requirements of labels of different sizes, and enhances the adaptability of the anti-counterfeiting label slitting equipment.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1-5 The slitting blade adjustment mechanism for an anti-counterfeiting label shown is located above the blade 1 and includes an adjustment component 3 and a linkage component 4.

[0026] Adjustment component 3 is used to adjust the position of blade 1. Adjustment component 3 includes housing 31 and moving block 35. Housing 31 can be installed on the output shaft of an external power unit. For example, the top of housing 31 can be fixedly connected to the bottom of the output shaft of an electric cylinder. Then, the electric cylinder drives the blade at the bottom of housing 31 to move up and down to cut the anti-counterfeiting labels on the slitting machine. Moving block 35 is connected to blade 1 through fixing component 5. Housing 31 is set as a cuboid with an opening at the bottom. A screw 33 is rotatably connected to the inner wall of housing 31. A knob 32 is fixedly connected to the right side of screw 33. The circumferential surface of knob 32 is provided with anti-slip texture. The central axis of knob 32 coincides with the central axis of screw 33. The outer wall of screw 33 is threadedly connected with threaded sleeve 34. The helix angle of screw 33 is less than the equivalent friction angle between tooth surfaces, so that when threaded sleeve 34 and screw 33 are engaged, threaded sleeve 34 will not move due to load changes. The number of moving blocks 35 is set to multiple. The outer wall of threaded sleeve 34 is fixedly connected to the inner wall of the leftmost moving block 35. Except for the leftmost moving block 35, the remaining moving blocks 35 have no contact relationship with screw 33. When screw 33 rotates, it will only affect the leftmost moving block 35.

[0027] The linkage assembly 4, used to adjust the spacing of the blades 1, is located on the top of the moving block 35. The linkage assembly 4 includes a first connecting rod 41 and a pin 43. Multiple first connecting rods 41 are hinged together end-to-end, with the middle of each connecting rod 41 hinged to the top of the moving block 35. These multiple connecting rods 41 form a transmission chain, transmitting the movement of the threaded sleeve 34 to other moving blocks 35, thus achieving synchronous movement of the multiple blades 1. The multiple first connecting rods 41 form a fork shape with their ends connected. A second connecting rod 42 is hinged to the right end of the rightmost first connecting rod 41. The inner wall of the end of the second connecting rod 42 furthest from the first connecting rod 41 rotates with the outer wall of the pin 43. The bottom of the pin 43 is fixedly connected to the top of the rightmost moving block 35, and the top of the pin 43 is fixedly connected to the top of the inner wall of the outer casing 31. The left end of the leftmost connecting rod 1 41 is hinged to the connecting rod 3 44. The end of the connecting rod 3 44 away from the connecting rod 1 41 is hinged to the top of the leftmost moving block 35. The length of the connecting rod 2 42 is equal to the length of the connecting rod 3 44, and the length of the connecting rod 1 41 is twice the length of the connecting rod 2 42. By rotating the screw 33, the multiple moving blocks 35 are extended or retracted at equal intervals through the linkage component 4, thereby keeping the spacing of the blade 1 stable and improving the uniformity of the anti-counterfeiting label slices.

[0028] like Figure 2 , Figure 4 , Figure 5As shown, the adjustment assembly 3 also includes a guide rod 36, which is fixedly connected to the inner wall of the housing 31. The outer wall of the guide rod 36 is slidably connected to the inner wall of the moving block 35. The number of guide rods 36 is set to two sets. The two sets of guide rods 36 and screws 33 are on the same horizontal plane and parallel to each other. By setting the guide rods 36, the stability of the moving block 35 during displacement is improved, so that the moving block 35 can make more precise linear movements.

[0029] like Figures 1-3 As shown, the fixing component 5 includes a protrusion 51, which is fixedly connected to the top of the blade 1. The bottom of the moving block 35 is provided with a groove 52. The protrusion 51 and the groove 52 are interference fit to achieve a stable connection. The protrusion 51 is inserted into the inner wall of the groove 52. The protrusion 51 is detachably connected to the moving block 35 by a fixing bolt 53. By setting the fixing component 5, it is convenient to install and replace the blade 1. When a single blade 1 is damaged, since the blade 1 is set separately at the bottom of the housing 31, the damaged blade 1 can be replaced individually without replacing the entire device, thus reducing material consumption and operating costs.

[0030] The working principle of this utility model is as follows: When adjusting the position and spacing of the blade 1, the operator first rotates the knob 32. The knob 32 drives the screw 33 to rotate. The thread of the screw 33 drives the threaded sleeve 34 to move along the axial direction of the screw 33. The movement of the threaded sleeve 34 drives the leftmost moving block 35 to move. Due to the limiting effect of the guide rod 36, the moving block 35 is linearly displaced along the axial direction of the screw 33. At the same time, the movement of the moving block 35 will drive the blade 1 at the bottom to move horizontally to adjust its cutting position.

[0031] Based on the above working principle, when the leftmost moving block 35 moves, through the hinged transmission of multiple connecting rods 41 in the linkage component 4, and the coordinated action of connecting rods 42 and 44, the other moving blocks 35 move synchronously and the spacing between the multiple moving blocks 35 remains equal. When the multiple moving blocks 35 are displaced, the blades 1 at the bottom of the moving blocks 35 follow the displacement, realizing that the multiple blades 1 unfold or retract at equal intervals, thereby keeping the spacing between the blades 1 stable, improving the uniformity of the anti-counterfeiting label slices, and is suitable for anti-counterfeiting label slitting machines, printing and cutting equipment and other scenarios, meeting the slitting requirements of labels of different sizes and improving the adaptability of anti-counterfeiting label slitting equipment.

[0032] 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.
