Description

Technical Field

[0001] This utility model relates to the technical field of die-cutting dies, and in particular to a die-cutting die mechanism and a die-cutting machine. Background Technology

[0002] In modern industrial production, die-cutting technology is widely used in packaging, labeling, electronics, printing, and many other fields. Die-cutting machines use die-cutting dies to cut materials (such as cardboard). As the diversity of die-cut samples increases, the patterns produced become more complex, and the forming requirements for die-cut products become more stringent.

[0003] In related technologies, the shapes cut by die-cutting dies are relatively rough, and there is a lot of waste material on the cut edges that cannot be peeled off from the material, requiring manual intervention and affecting product forming. Utility Model Content

[0004] To overcome the technical problems of low product forming efficiency caused by the rough shape and excessive waste marks on the cutting edge of existing die-cutting dies, this utility model provides a die-cutting die mechanism, including a kit and a cutter. The kit has a cavity that runs vertically through the cavity. The cutter is disposed in the cavity and has a blade tip and a limiting part. The peripheral wall of the limiting part is in contact with the peripheral wall of the cavity. The kit drives the blade tip to extend out of the cavity or retract into the cavity.

[0005] Furthermore, it also includes a connector, the kit having a first position and a second position relative to the connector, the kit being in the first position with the blade tip extending out of the cavity; the kit being in the second position with the blade tip extending into the cavity.

[0006] Furthermore, the connector has an upper and lower communicating mounting cavity, and the kit is fitted into the mounting cavity and slidably connected to the mounting cavity.

[0007] Furthermore, it also includes an adjustment element for connecting the kit, the cutting tool, and the connector.

[0008] Furthermore, the adjusting component includes a positioning shaft, which is fixedly connected to the cutting tool.

[0009] Furthermore, the kit has a sliding hole that communicates with the cavity, and the end of the positioning shaft away from the tool passes through the sliding hole. The positioning shaft has a first position and a second position.

[0010] Furthermore, the adjusting component also includes an adjusting pad, the connecting component has a positioning hole that communicates with the mounting cavity, the adjusting pad is located on the outer wall of the connecting component, the positioning shaft passes through the sliding hole, and the positioning hole is fixedly connected to the adjusting pad.

[0011] Furthermore, the cross-section of the cutting tool, the kit, and the connector is circular.

[0012] This utility model also provides a die-cutting machine, including a drive motor and a waste discharge roller. The drive motor is installed at one end of the waste discharge roller and is used to drive the waste discharge roller to move. It also includes a die-cutting die mechanism as described above, which is installed at the other end of the waste discharge roller.

[0013] Furthermore, the end of the kit away from the cutter is sleeved on the end of the waste discharge roller away from the drive motor, and the connecting piece is fixedly installed on the waste discharge roller.

[0014] Beneficial effects:

[0015] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0016] The kit has a through-cavity housing, within which the cutting tool is mounted. The peripheral wall of the cutting tool's limiting portion conforms to the peripheral wall of the cavity. The cutting tool can reciprocate along the length of the cavity. The cavity restricts the wobble of the cutting tip, ensuring stable extension and retraction of the tip from and out of the cavity without displacement. The cutting tip moves in a predetermined direction and cuts onto materials (e.g., cardboard), forming a precise pattern and avoiding the limitations of existing methods. The existing technology suffers from the drawback of producing rough shapes and leaving numerous waste marks on the cut edges. When the kit moves downwards relative to the cutter, the cutter's tip moves upwards until it extends from the cavity and penetrates the material (e.g., cardboard) for cutting. After cutting, the tip retracts into the cavity, carrying away waste from the material (e.g., cardboard) during the retraction process. Most of the waste is confined outside the cavity, completing the process of removing waste glass material (e.g., cardboard). This avoids the technical drawback of the existing technology where a significant amount of waste remains on the cut edges. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] Please refer to Figures 1 to 2 A die-cutting die mechanism includes a kit 1 and a cutter 2. The kit 1 has a cavity 11 that extends vertically through the cavity 11. The cutter 2 is disposed in the cavity 11 and has a blade tip 21 and a limiting portion 22. The peripheral wall surface of the limiting portion 22 is in contact with the peripheral wall surface of the cavity 11. The kit 1 drives the blade tip 21 to extend out of the cavity 11 or retract into the cavity 11.

[0024] In this technical solution, the kit 1 has a through cavity 11, and the cutter 2 is installed in the cavity 11. The peripheral wall of the limiting part 22 of the cutter 2 is in contact with the peripheral wall of the cavity 11. The cutter 2 can move back and forth along the length of the cavity 11. The cavity 21 of the kit 2 restricts the wobbling of the cutting tip 21 of the cutter 2, so that the cutting tip 21 can stably extend out of or retract into the cavity 11 without displacement. The cutting tip 21 can move along a predetermined direction and cut on the material (e.g., cardboard). The material (e.g., cardboard) can be cut into a predetermined shape, and the cut pattern is relatively... It is precise and avoids the technical defects of existing technologies, such as rough shapes and a lot of waste traces on the cutting edge. When the kit 1 moves downward relative to the cutter 2, the tip 21 of the cutter 2 moves upward until the tip 21 of the cutter 2 extends out of the cavity 11 and penetrates into the material (e.g., cardboard) for cutting. After cutting, the tip 21 retracts into the cavity 11. During the retraction, the tip 21 carries away the waste on the material (e.g., cardboard). Most of the waste is restricted outside the cavity 11, completing the action of waste glass material (e.g., cardboard). This avoids the technical defects of existing technologies, such as a lot of waste that cannot be removed from the cutting edge.

[0025] The specific embodiment of the kit 1 driving the blade tip 21 to extend outside the cavity 11 or retract inside the cavity 11 is described in the following example. Figure 1 and Figure 2 As shown, it also includes a connector 3. The kit 1 has a first position and a second position relative to the connector 3. When the kit 1 is in the first position, the blade tip 21 extends out of the cavity 11. When the kit 1 is in the second position, the blade tip 21 extends into the cavity 11. In this embodiment, the connector 3, the kit 1, and the cutter 2 are connected sequentially from the outside to the inside. The connector 3 has an upper and lower communicating mounting cavity 31. The kit 1 is fitted into the mounting cavity 31 and slidably connected to the mounting cavity 31, so that the kit 1 has a first position and a second position relative to the connector 3. When the kit 1 moves to the first position, the kit 1 moves downward relative to the connector 3, and the cutter 2 moves upward relative to the kit 1, so that the tip 21 of the cutter 2 moves upward and extends out of the cavity 11. When the kit 1 moves to the second position, the kit 1 moves downward relative to the connector 3, and the cutter 2 moves downward relative to the kit 1, so that the tip 21 of the cutter 2 moves downward and retracts into the cavity 11. The overall structure is simple. Preferably, the cross-section of the cutter 2, the kit 1, and the connector 3 is circular, and the diameter is usually small, which is suitable for fine die cutting and for the removal of small area waste or fine patterns, such as labels, small packaging boxes, etc. It causes little damage to the material and is suitable for high-precision die cutting.

[0026] Furthermore, by Figure 1 and Figure 2 As shown, it also includes an adjusting component 4, which is used to connect the kit 1, the cutter 2 and the connector 3, and to adjust the relative positions between the kit 1, the cutter 2 and the connector 3.

[0027] Specifically, the assembly relationship between the cutting tool 2 and the adjusting component 4 is determined by... Figure 2 As shown, the adjusting component 4 includes a positioning shaft 41, which is fixedly connected to the cutting tool 2 and can drive the cutting tool 2 to move.

[0028] Furthermore, the assembly relationship between the positioning axis 41 and the tool 2 in kit 1 is determined by... Figure 2 As shown, the kit 1 has a sliding hole 12, which communicates with the cavity 11. The end of the positioning shaft 41 away from the cutter 2 passes through the sliding hole 12. The positioning shaft 41 has a first position and a second position. In this embodiment, for structural stability, two sliding holes 12 are provided, which are symmetrically arranged. The positioning shaft 41 passes through the two sliding holes 12 and drives the cutter 2 to move up and down along the length of the sliding hole 12, thereby driving the tip portion 21 of the cutter 2 to extend out of or retract into the cavity 11. When the positioning shaft 41 moves to the first position, it moves towards the tip portion 21, and the kit 1 moves downward relative to the connecting member 3, causing the tip portion 21 to move upward and extend out of the cavity 11. When the positioning shaft 41 moves to the second position, it moves towards the limiting portion 22, and the kit 1 moves upward relative to the connecting member 3, causing the tip portion 21 to move downward and retract into the cavity 11.

[0029] Furthermore, the assembly relationship of the positioning shaft 41, the tool 2, and the kit 1 on the connecting member 3 is determined by... Figure 2 As shown, the adjusting component 4 also includes an adjusting pad 42. The connecting component 3 has a positioning hole 32, which communicates with the mounting cavity 31. The adjusting pad 42 is located on the outer wall of the connecting component 3. The positioning shaft 41 passes through the sliding hole 12, and the positioning hole 32 is fixedly connected to the adjusting pad 42. In this embodiment, for structural stability, two positioning holes 32 are provided, symmetrically arranged. The positioning shaft 41 passes through the sliding hole 12, and the positioning hole 32 is fixedly connected to the adjusting pad 42. The cutting tool 2 and the kit 1 are connected in the mounting cavity 31 of the connecting component 3. The adjusting pad 42 is installed on the outer wall of the connecting component 3. By moving the position of the adjusting pad 42, the kit 1 moves relative to the connecting component 3, thereby allowing the cutting tip 21 of the cutting tool 2 to extend out of or retract into the cavity 11. The operation is convenient, simple, and highly flexible.

[0030] This utility model also provides a die-cutting machine, including a drive motor and a waste discharge roller. The drive motor is installed at one end of the waste discharge roller and is used to drive the waste discharge roller to move. It also includes a die-cutting die mechanism as described above, installed at the other end of the waste discharge roller. Several of these die-cutting die mechanisms can be customized according to the shape of the die-cutting pattern and the distribution of waste material, suitable for complex patterns or irregularly shaped die-cutting waste materials, such as irregular packaging boxes, art cards, etc. It offers high flexibility and is suitable for personalized production. The end of the kit 1 away from the cutter 2 is fitted onto the end of the waste discharge roller away from the drive motor, and the connecting piece is fixedly installed on the waste discharge roller. When the drive motor starts, the waste discharge roller moves towards the cutter 2, abutting against the limiting portion 22 of the cutter 2, allowing the blade tip 21 to extend from the cavity 11. When the drive motor stops operating, the waste discharge roller returns to its natural state, separating from the limiting portion 22 of the cutter 2, and the blade tip 21 retracts into the cavity 11. Operation is simple.
