[0002] In industries such as packaging, printing, and advertising production, self-adhesive cutting equipment is a key piece of equipment for cutting self-adhesive materials to specific specifications, providing a basic guarantee for the advancement of subsequent processes.

[0003] Existing cutting equipment using transmission methods such as gears and toothed belts suffers from insufficient rigidity, susceptibility to vibration, and transmission slippage. This results in poor positioning accuracy and stability of the cutting components during movement, affecting not only the flatness of the cut interface but also limiting further increases in cutting speed, making it difficult to meet the demands for high-speed, high-precision cutting. Therefore, there is an urgent need for a self-adhesive label cutting device with sufficient transmission rigidity, stable operation, and the ability to adapt to high-speed operations. Utility Model Content

[0004] This invention solves the problems mentioned in the background art by using a cutting motor to drive a lead screw to rotate, and with the guidance of a linear guide rail, driving the cutting component that works with the lead screw to reciprocate linearly along the linear guide rail.

The cutting assembly includes a drive block that forms a helical transmission pair with the lead screw, a guide block that is slidably connected to the linear guide rail, and a cutter mounted on the drive block. The cutting motor drives the lead screw to rotate, which in turn causes the cutting assembly to reciprocate linearly along the linear guide rail, thereby cutting the self-adhesive material.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 : Example 1: This embodiment provides a self-adhesive label cutting device, including a workbench 1, and further comprising: The drive mechanism 2 includes a cutting motor 20 mounted on one side of the worktable 1, a lead screw 21 driven to rotate by the cutting motor 20, and a linear guide rail 22 connected to the worktable 1. The cutting assembly 3 includes a drive block 30 that forms a helical transmission pair with the lead screw 21, a guide block 31 that is slidably connected to the linear guide rail 22, and a cutter 32 mounted on the drive block 30. The cutting motor 20 drives the lead screw 21 to rotate, which in turn drives the cutting assembly 3 to reciprocate linearly along the linear guide rail 22, thereby cutting the self-adhesive material 8.

[0018] The workbench 1 is mostly constructed as a rectangular plate or platform to accommodate material conveying and cutting operations, and serves as an installation platform for the drive mechanism 2, cutting assembly 3, and other auxiliary components.

[0019] The drive mechanism 2 includes a cutting motor 20, a lead screw 21, and a linear guide rail 22, which provide power to the cutting assembly 3 and guide its movement trajectory. The cutting motor 20 is the power source of the drive mechanism 2. It is a motor with rotary drive function and is bolted to one side of the worktable 1. Its output end is connected to the lead screw 21 through a coupling, and is used to drive the lead screw 21 to rotate by outputting rotary motion. The lead screw 21 is the transmission component in the drive mechanism 2. It is constructed as a rod-shaped structure with helical patterns on its surface. It is connected to the cutting motor 20 and parallel to the linear guide rail 22. It is used to convert the rotary motion of the cutting motor 20 into the linear motion of the drive block 30 and forms a helical transmission pair with the drive block 30. The linear guide rail 22 is the guide component in the drive mechanism 2. It is constructed as a long strip structure with a slide rail. It is detachably fixed to the worktable 1 by bolts and is parallel to the lead screw 21. It is used to limit the movement direction of the cutting assembly 3 and ensure that it moves smoothly along a straight line. It is slidably connected to the guide block 31.

[0020] The cutting assembly 3 includes a drive block 30, a guide block 31, and a cutter 32, used for cutting the self-adhesive material 8. The drive block 30 is a transmission connector in the cutting assembly 3, constructed as a block structure with internal threads, sleeved on the lead screw 21 and connected to the guide block 31 and the cutter 32, used to convert the rotational motion of the lead screw 21 into its own linear motion, driving the cutter 32 to move. The guide block 31 is a guide connector in the cutting assembly 3, constructed as a block structure adapted to the linear guide rail 22, one end adapted to the cross-sectional shape of the linear guide rail 22 to ensure sliding connection, and the other end integrally formed with the drive block 30, used to cooperate with the linear guide rail 22 to limit the movement trajectory of the cutting assembly 3 and ensure smooth movement. The cutter 32 is a cutting execution component in the cutting assembly 3, constructed as a sheet structure with a blade, installed on the drive block 30 and corresponding to the cutting position of the self-adhesive material 8, used to cut the self-adhesive material 8 under the drive of the drive block 30.

[0021] According to the above design, during cutting, the cutting motor 20 starts and drives the lead screw 21 to rotate. Since the drive block 30 and the lead screw 21 form a helical transmission pair, the rotation of the lead screw 21 drives the drive block 30 to move linearly along the axis of the lead screw 21. At the same time, the guide block 31 slides with the linear guide rail 22 to ensure that the drive block 30 and the cutter 32 mounted on it move smoothly back and forth along the direction of the linear guide rail 22. When the cutter 32 moves with the cutting assembly 3, it contacts the self-adhesive material 8 and completes the cutting action. The continuous cutting of the self-adhesive material 8 is achieved through the reciprocating motion of the cutting assembly 3.

[0022] It also includes a feeding roller 4 and a discharging roller 5 for conveying the self-adhesive material 8, with the drive mechanism 2 located between the feeding roller 4 and the discharging roller 5. The purpose of this design is to achieve continuous and stable conveying of the self-adhesive material 8 by setting the feeding roller 4 and the discharging roller 5. The two are fixedly installed at the inlet and outlet ends of the worktable 1 by bearing seats or support seats, respectively, and each is equipped with an independent motor. The feeding roller 4 is driven by the motor to rotate and convey the self-adhesive material 8 to be cut to the cutting area where the drive mechanism 2 is located in the middle. The discharging roller 5 rotates synchronously under the drive of the motor to discharge the cut material outward. The drive mechanism 2 is located between the two, so that the cutting component 3 can accurately dock with the material being conveyed, ensuring that the cutting action and the material conveying are coordinated, without the need for manual assistance in loading and unloading, and maintaining the continuity of the cutting process.

[0023] The cutter 32 is a double-edged blade. The purpose of this design is to fully utilize the reciprocating motion of the cutting assembly 3 by making the cutter 32 a double-edged blade. The double-edged blade has a sheet-like structure with blades on both sides. When the cutting assembly 3 moves in one direction under the drive mechanism 2, one blade of the cutter 32 can cut the self-adhesive material 8; during the return motion, the other blade can continue to perform the cutting action, avoiding idleness during the return stroke. This ensures that the reciprocating motion of the cutting assembly 3 is converted into effective cutting operations, reducing time consumption caused by ineffective motion, ensuring the continuity of the cutting process, and adapting to the needs of batch cutting.

[0024] The cutter 32 and the drive block 30 are detachably connected. The purpose of this design is to facilitate the replacement and maintenance of the cutter 32 by making the connection between the cutter 32 and the drive block 30 detachable. A bolt connection is preferred for this detachable connection. Specifically, the connection points of the cutter 32 and the drive block 30 are provided with corresponding screw holes, through which bolts are passed to secure the two. When the cutter 32 experiences blade wear due to long-term use, or when it needs to be replaced with a different type of cutter 32 according to the different specifications of the self-adhesive material 8, simply unscrew the bolts to remove the old cutter 32, replace it with a new cutter 32, and then tighten the bolts to complete the fixation. No adjustments to other parts of the equipment are required. The operation is simple and convenient, reducing downtime caused by replacing the cutter 32 and ensuring continuous cutting operations.

[0025] It also includes a clamping mechanism 6, located above the worktable 1, for clamping the self-adhesive material 8 before cutting. The purpose of this design is to fix the self-adhesive material 8 before the cutting work begins by setting the clamping mechanism 6 above the worktable 1, so as to avoid the material shifting or wrinkling during the cutting process.

[0026] The clamping mechanism 6 includes a crossbeam 60, a clamping drive 61, and a clamping part 62. The crossbeam 60 spans across the workbench 1, the clamping drive 61 is mounted on the top of the crossbeam 60, and the clamping part 62 is connected to the output end of the clamping drive 61 and can be driven by it to move up and down. The purpose of this design is to achieve stable clamping of the self-adhesive material 8 through the coordinated operation of the crossbeam 60, the electric cylinder, and the clamping part 62. The crossbeam 60 is a long strip-shaped plate structure, with both ends fixed to the two sides of the workbench 1 by bolts, spanning across the workbench 1 to form a stable support. The clamping drive 61 is an electric cylinder with linear power output function, which is fixedly mounted on the top of the crossbeam 60 by bolts. The clamping part 62 is connected to the output end of the electric cylinder and is used to clamp the self-adhesive material 8. When it is necessary to clamp the material, the electric cylinder starts and outputs power, driving the clamping part 62 to move downward until it contacts the self-adhesive material 8 on the surface of the worktable 1 and applies pressure. After the cutting is completed, the electric cylinder drives the clamping part 62 to move upward and reset, releasing the clamping of the material. Through this liftable structure design, the material can be firmly fixed before cutting without affecting the material conveying and the output after cutting, ensuring the smoothness of the cutting process.

[0027] The clamping part 62 includes a connecting frame 620, two lower support blocks 621 and an upper pressure block 622. The connecting frame 620 is fixed to the output end of the clamping drive member 61. The two lower support blocks 621 are respectively fixed to the opposite sides of the crossbeam 60. The upper pressure block 622 is fixed to the bottom of the connecting frame 620 and corresponds vertically to the position of the lower support blocks 621. The purpose of this design is to achieve balanced clamping of the self-adhesive material 8 through the cooperation of the connecting frame 620, two lower support blocks 621, and upper pressure block 622. The connecting frame 620 is a frame structure, with its top fixed to the output end of the electric cylinder by bolts, providing mounting support for the upper pressure block 622. The two lower support blocks 621 are both block-shaped structures, respectively fixed to opposite sides of the crossbeam 60 by welding, and kept flush with the surface of the worktable 1. The upper pressure block 622 is a block structure adapted to the lower support blocks 621, fixed to the bottom of the connecting frame 620 by bolts, and its position corresponds vertically to the two lower support blocks 621. When the electric cylinder drives the connecting frame 620 to descend, the upper pressure block 622 moves down synchronously with the connecting frame 620, cooperating with the two lower support blocks 621 below to apply pressure from above, so that the material is stably clamped between them, avoiding displacement or wrinkling during cutting. The corresponding clamping structure on both sides ensures that the material is subjected to uniform force, ensuring a smooth cutting process.

[0028] The bottom of the upper pressure block 622 and the top of the lower support block 621 are provided with buffer pads 7 made of elastic material. The purpose of this design is to fix the buffer pads 7 made of elastic material to the bottom of the upper pressure block 622 and the top of the lower support block 621 by adhesive bonding. The elastic material of the buffer pads 7 can be selected from rubber, silicone, or polyurethane, etc., forming a flexible contact when pressing the self-adhesive material 8. The buffer pads 7 conform to the shape of the bottom of the upper pressure block 622 and the top of the lower support block 621. When the electric cylinder drives the upper pressure block 622 to descend and cooperate with the lower support block 621 to press the material, the buffer pads 7 can absorb part of the pressing force, avoiding indentation or damage to the material surface caused by rigid contact. At the same time, with the help of the deformation characteristics of the elastic material, the pressing force is applied to the material more evenly, further enhancing the stability of the material fixation, and can adapt to the slight undulations of the material surface, ensuring that the material remains flat during the cutting process.

[0029] According to this embodiment, during operation, the self-adhesive material 8 enters the working area via the feeding roller 4 and is received by the lower support block 621. After reaching the preset position, the control console controls the electric cylinder to drive the connecting frame 620 to descend, so that the upper pressure block 622 and the lower support block 621 come into contact and apply a clamping force to the material. Subsequently, the control console coordinates the start of the cutting motor 20 and drives the lead screw 21 to rotate, causing the drive block 30 to move in one direction along the linear guide rail 22. One side of the double-edged cutter 32 completes one cut. After cutting, the control console controls the electric cylinder to rise and reset, and the feeding roller 4 pushes the material a certain distance. Then, the electric cylinder descends again, so that the upper pressure block 622 and the lower support block 621 cooperate to clamp the material. The cutting motor 20 drives the lead screw 21 to rotate in the opposite direction, causing the drive block 30 to move back. The other side of the double-edged cutter 32 completes a second cut, constituting a complete reciprocating cutting operation. The discharge roller 5 simultaneously discharges the cut material. All components are connected in an orderly manner under the coordination of the control console. The buffer pad 7 prevents damage to the material surface. The bidirectional cutting, continuous conveying, and pressing actions work together to ensure a smooth cutting process, guaranteeing neat cuts and maintaining the material's stability at all times. The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
