Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to an automatic blade-changing label die-cutting machine. Background Technology

[0002] Label die-cutting machines are mechanical equipment used to process paper products such as paper boxes and cartons, and to perform die-cutting, creasing and waste removal. They can meet the die-cutting requirements of various specifications and sizes, and can also perform operations such as slitting, rolling and folding of paper.

[0003] However, traditional label die-cutting machines often lack guiding mechanisms, which can easily cause material to shift during the cutting process, resulting in cutting errors. Secondly, the power transmission path of traditional label die-cutting machines is complex, which limits the stability and response speed of the cutting mechanism, making it difficult to achieve efficient and precise cutting operations. In addition, traditional label die-cutting machines usually use manual blade changing, a cumbersome and inefficient process that not only increases the difficulty of operation and labor intensity but also hinders the improvement of production efficiency and cost reduction.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0016] like Figures 1-5 As shown, the present invention proposes an automatic blade-changing label die-cutting machine, which includes a die-cutting machine body 1, a cutting component 2 on the die-cutting machine body 1, and a rotary blade-changing component 3 at the bottom of the cutting component 2.

[0017] The cutting assembly 2 includes a pair of telescopic cylinders 21 symmetrically arranged on the die-cutting machine body 1. The telescopic cylinders 21 adjust the position of the side baffles 22 by telescopic rods to accommodate materials of different sizes. The top of the telescopic rods of both telescopic cylinders 21 are equipped with baffles 22 to prevent the material from shifting during the cutting process and to ensure the accuracy of the cutting. The die-cutting machine body 1 is equipped with a support frame 23, which provides the mounting base for other components in the cutting assembly 2. The top of the support frame 23 is equipped with a motor 24, which provides power to drive the rotating shaft 25 to rotate. The transmission end of the motor 24 is equipped with the rotating shaft 25, which provides the mounting base for the sprocket 26 and the second sprocket 27 and transmits the rotational power of the motor 24. The sprocket 26 is sleeved on the outside of the rotating shaft 25, and the second sprocket 27 is sleeved on the outside of the rotating shaft 25. The second sprocket 27 is located directly below the sprocket 26.

[0018] A pair of support seats 28 are symmetrically arranged on the inner wall of one side of the support frame 23. The support seats 28 provide stable support for the lead screw 29, ensuring the stability of the lead screw 29 during rotation. The lead screw 29 is inserted into the two support seats 28. A sprocket 210 is fitted on the top of the lead screw 29 at the position corresponding to the sprocket 26. A transmission chain 217 is arranged between the sprocket 26 and the sprocket 210. When the motor 24 drives the shaft 25, sprocket 26, and sprocket 27 to rotate, the sprocket 26 transmits power to the sprocket 210 through the transmission chain 217, thereby driving the lead screw 29 to rotate. The support frame 23 moves away from the lead screw. A pair of support seats 211 are symmetrically arranged on one inner wall of rod 29. Support seats 211 provide stable support for lead screw 212, ensuring the stability of lead screw 212 when rotating. Lead screw 212 is inserted into the two support seats 211. A sprocket 4 213 is sleeved on the top of lead screw 212 at the position corresponding to sprocket 27. A transmission chain 214 is arranged between sprocket 27 and sprocket 4 213. When motor 24 drives shaft 25, sprocket 26 and sprocket 27 to rotate, sprocket 27 transmits power to sprocket 4 213 through transmission chain 214, thereby driving lead screw 212 to rotate.

[0019] Lead screw 29 and lead screw 212 rotate in the same direction and rotate synchronously, converting the rotational motion of lead screw 29 and lead screw 212 into the linear motion of drive block 215, thereby controlling the lifting and lowering of cutter 39. Drive block 215 is spirally sleeved on the outer side of lead screw 29 and lead screw 212. Drive block 215 provides the mounting base for rotary blade changing assembly 3. A pair of lifting guide rails 216 are provided on both sides of support frame 23. Drive block 215 is slidably mounted on lifting guide rails 216. Lifting guide rails 216 provide the track for linear motion of drive block 215, ensuring the stability of drive block 215 during lifting and lowering.

[0020] The rotary tool changer assembly 3 includes a mounting box 31 located on one side of the bottom of the drive block 215. The mounting box 31 provides a mounting base for other components in the rotary tool changer assembly 3. A telescopic cylinder 32 is provided on one side of the mounting box 31. The telescopic rod of the telescopic cylinder 32 passes through the mounting box 31. The rack 33 is driven to move by the extension and retraction of the telescopic rod of the telescopic cylinder 32. The rack 33 is located at the top of the telescopic rod of the telescopic cylinder 32. The rack 33 meshes with the gear 37 to transmit power. A slide rail 34 is provided inside the mounting box 31. The rack 33 is slidably mounted in the slide rail 34. The slide rail 34 provides a moving track for the rack 33 to ensure the stability of the rack 33 when it moves. A cover plate 310 is provided on one side of the mounting box 31 to protect the components inside the mounting box 31.

[0021] A pair of bearing seats 35 are symmetrically arranged at the bottom of the drive block 215. The bearing seats 35 support the second rotating shaft 36 to ensure its stable rotation. The second rotating shaft 36 is inserted into the two bearing seats 35. One end of the second rotating shaft 36 passes through the cover plate 310. The second rotating shaft 36 provides a mounting base for the mounting seat 38 and the cutter 39. A gear 37 is sleeved on the outer side of one end of the second rotating shaft 36. The gear 37 meshes with the rack 33. The telescopic cylinder 32 drives the rack 33 to move along the slide rail 34 through the telescopic rod. The rack 33 transmits power to the gear 37 through meshing, thereby driving the second rotating shaft 36 to rotate and realize the function of automatic blade changing. Several mounting seats 38 are arranged on the outer side of the second rotating shaft 36. Each mounting seat 38 is equipped with a cutter 39. The cutter 39 located directly below directly acts on the label to perform the cutting operation. When a cutter 39 is worn and no longer sharp, other spare cutters 39 can be rotated to the lower position to continue the cutting operation, avoiding the time cost of changing cutters 39 midway.

[0022] In use, the user can first adjust the baffles 22 on both sides according to the size of the material to be cut. The extension and retraction of the telescopic rod of the telescopic cylinder 21 allows the baffles 22 on both sides to move closer or further apart, preventing the material to be cut from shifting and causing inaccurate cutting. Then, the motor 24 drives the rotating shaft 25 to rotate. When the rotating shaft 25 rotates, it drives the sprockets 26 and 27 to rotate synchronously. The sprocket 26 drives the sprocket 210 to rotate through the transmission chain 217, and the sprocket 27 drives the sprocket 213 to rotate through the transmission chain 214, thereby achieving... Lead screw 29 and lead screw 212 rotate synchronously, with lead screw 29 and lead screw 212 rotating in the same direction. The rotational motion of lead screw 29 and lead screw 212 is converted into linear motion of drive block 215, causing drive block 215 and other components installed at its bottom to descend along lifting guide rail 216, so that cutter 39 cuts material. After cutting, motor 24 drives shaft 25 to reverse, causing drive block 215 and other components installed at its bottom to rise along lifting guide rail 216. The above steps are repeated until the material cutting operation is completed.

[0023] After a period of use, the cutter 39 will become dull due to wear. The user can control the telescopic rod of the telescopic cylinder 32 to extend and retract, driving the rack 33 to move along the slide rail 34. The rack 33 transmits power to the gear 37 through meshing, thereby driving the rotating shaft 36 to rotate and turn the other spare cutters 39 on the rotating shaft 36 to the bottom, realizing the function of automatic cutter changing, ensuring the smooth progress of cutting operations, avoiding frequent manual replacement of cutters 39, and reducing production efficiency.

[0024] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
