Description

Technical Field

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

[0002] In modern industrial production, die-cutting technology is widely used in packaging, labeling, electronics, printing and other fields.

[0003] Die-cutting machines typically include a feed rack for feeding alignment and tension balancing. In existing technology, the feed rack, in addition to the support frame and feeding platform, also includes a pressure roller or pressure plate, fixedly connected to the support frame to prevent the die-cutting material from bouncing. However, when the gap between the pressure plate and the feeding platform is too small, the die-cutting material cannot enter the gap; when the gap is too large, the bouncing of the die-cutting material is significant, resulting in greater action and reaction forces between the die-cutting material and the pressure plate, easily causing scratches on the die-cutting material, especially during high-speed die-cutting, where the scratches are more severe. Utility Model Content

[0004] To overcome the technical problem of uncontrollable material feeding gap in existing die-cutting machines, this utility model provides a die-cutting machine feeding mechanism, including a base; a first roller, including a first rotating roller body, with one end of the first roller away from the first rotating roller body connected to the base; a second roller assembly, including a second rotating roller body, an adjusting section, and a sliding section, the adjusting section and the sliding section being connected to the second rotating roller body, the adjusting section being connected to the base and having a first position and a second position relative to the base; a power assembly, mounted on the base, the sliding section being connected to the power assembly and having a first rotation direction and a second rotation direction relative to the power assembly, wherein when the power assembly is in the first rotation direction, the adjusting section is in the first position, and the sliding section drives the second rotating roller body closer to the first rotating roller body; when the power assembly is in the second rotation direction, the adjusting section is in the second position, and the sliding section drives the second rotating roller body away from the first rotating roller body.

[0005] Furthermore, the power assembly includes a drive source and a cam, one end of the drive source is fixedly connected to the base, and the other end of the drive source is rotatably connected to the cam. The cam has a first rotation direction and a second rotation direction, and the sliding segment is connected to the cam.

[0006] Furthermore, it also includes a roller, which is rotatably connected to the sliding section and moves along the outer contour of the cam.

[0007] Furthermore, the outer contour of the cam has an elliptical structure.

[0008] Furthermore, the sliding section includes a connecting rod, one end of which is fixedly connected to the second rotating roller, and the other end of which is rotatably connected to the roller.

[0009] Furthermore, the adjustment section includes a tension rod and an airbag, one end of the airbag being fixedly connected to the base, and the other end of the airbag being fixedly connected to the tension rod.

[0010] Furthermore, the tension rod is hinged to the sliding section.

[0011] Furthermore, there is an angle between the adjusting section and the sliding section.

[0012] Beneficial effects:

[0013] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0014] One end of the first roller is fixedly connected to the base, and the end of the first roller away from the base is also connected. An adjusting section, a second rotating roller, and a sliding section are sequentially connected together to form a second roller assembly. The sliding section is connected to a power assembly, and the end of the power assembly away from the sliding section is mounted on the base. The adjusting section is connected to the base and can move on the base. The adjusting section has a first position and a second position relative to the base, and the sliding section has a first rotation direction and a second rotation direction relative to the power assembly. The adjusting section is used to pull the sliding section so that the sliding section can continuously move with the first rotation direction or the second rotation direction of the power assembly, causing the second rotating roller to move closer to or away from the first rotating roller. When the power assembly is in the first rotation direction, the adjusting section is in the first position, and the sliding section causes the second rotating roller to move closer to the first rotating roller. When the power assembly is in the second rotation direction, the adjusting section is in the second position, and the sliding section causes the second rotating roller to move away from the first rotating roller. The movement of the second roller assembly is controlled by the power component. The second rotating roller moves closer to or further away from the first rotating roller, making the material feed gap between the two rotating rollers controllable. This avoids the technical defects in the prior art where the material feed gap is too small, preventing the die-cutting material from entering the gap, and where the material feed gap is too large, easily causing scratches on the die-cutting material.

[0020] 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.

[0021] Please refer to Figures 1 to 2 A die-cutting machine feeding mechanism includes a base 1; a first roller 2, including a first rotating roller body 21, with one end of the first roller 2 away from the first rotating roller body 21 connected to the base 1; a second roller assembly 3, including a second rotating roller body 31, an adjusting section 32, and a sliding section 33, the adjusting section 32 and the sliding section 33 being connected to the second rotating roller body 31, the adjusting section 32 being connected to the base 1 and having a first position and a second position relative to the base 1; and a power assembly 4, mounted on the base 1, the sliding section 33 being connected to the power assembly 4 and having a first rotation direction and a second rotation direction relative to the power assembly 4. When the power assembly 4 is in the first rotation direction, the adjusting section 32 is in the first position, and the sliding section 33 drives the second rotating roller body 31 closer to the first rotating roller 21; when the power assembly 4 is in the second rotation direction, the adjusting section 32 is in the second position, and the sliding section 33 drives the second rotating roller 31 away from the first rotating roller 21.

[0022] In this technical solution, one end of the first roller 2 is fixedly connected to the base 1, and the end of the first roller 2 away from the base 1; the adjusting section 32, the second rotating roller body 31, and the sliding section 33 are sequentially connected together to form the second roller assembly 3. The sliding section 33 is connected to the power assembly 4, and the end of the power assembly 4 away from the sliding section 33 is mounted on the base 1. The adjusting section 32 is connected to the base 1 and can move on the base 1. The adjusting section 32 has a first position and a second position relative to the base 1, and the sliding section 33 has a first rotation direction and a second rotation direction relative to the power assembly 4. The adjusting section 32 is used for pulling... The sliding section 33 is pulled so that it can continuously move with the first or second rotation direction of the power assembly 4, causing the second rotating roller 31 to move closer to or away from the first rotating roller 21. When the power assembly 4 is in the first rotation direction, the adjusting section 32 is in the first position, and the sliding section 33 causes the second rotating roller 31 to move closer to the first rotating roller 21. When the power assembly 4 is in the second rotation direction, the adjusting section 32 is in the second position, and the sliding section 33 causes the second rotating roller 31 to move away from the first rotating roller 21. By controlling the movement of the second roller assembly 3 through the power assembly 4, the second rotating roller 31 moves closer to or away from the first rotating roller 21, making the material passage gap between the second rotating roller 31 and the second rotating roller 21 controllable. This avoids the technical defects in the prior art where the material passage gap is too small, preventing the die-cutting material from entering the gap, and where the material passage gap is too large, easily causing scratches on the die-cutting material.

[0023] The specific embodiments of the power component 4 are as follows: Figure 2 As shown, the power assembly 4 includes a drive source 41 and a cam 42. One end of the drive source 41 is fixedly connected to the base 1, and the other end of the drive source 41 is rotatably connected to the cam 42. The cam 42 has a first rotation direction and a second rotation direction, and the sliding segment 33 is connected to the cam 42. The driving source 41 is a drive motor, which is fixed on the base 1. The drive shaft of the drive motor is away from the base 1. The cam 42 is mounted on the drive shaft of the drive motor. When the drive motor drives, it drives the cam 42 to rotate. In this embodiment, the sliding segment 33 can move along the outer contour of the cam 42. Preferably, the outer contour of the cam 42 is elliptical. The cam 42 has a first rotation direction and a second rotation direction. When the cam 42 rotates along the first rotation direction, the adjusting segment 32 is in the first position, the sliding segment 33 rotates with the first rotation direction, and the second rotating roller 31 moves closer to the first rotating roller 21. When the cam 42 rotates along the second rotation direction, the adjusting segment 32 is in the second position, the sliding segment 33 rotates with the second rotation direction, and the second rotating roller 31 moves away from the first rotating roller 21.

[0024] In this embodiment, the sliding section 33 is connected to the outer contour of the cam 42 via the roller 5. Specifically, the die-cutting machine feeding mechanism also includes the roller 5, which is rotatably connected to the sliding section 33 and moves along the outer contour of the cam 42. During the rotation of the cam 42, the adjusting section 32 continuously pulls the sliding section 33, allowing the roller 5 to continuously move along the outer contour of the cam 42. An angle 6 exists between the adjusting section 32 and the sliding section 33, and the roller 5 moves continuously towards the angle 6. When the small radius of the cam 42 contacts the roller 5, i.e., the power assembly 4 is in the second rotation direction, the adjusting section 32 is in the second position, and the sliding section 33 drives the second rotating roller 31 away from the first rotating roller 21. When the power assembly 4 rotates from the second rotation direction to the first rotation direction, the adjusting section 32 moves from the second position to the first position, pulling the sliding section 33 so that the large radius of the cam 42 contacts the roller 5, and the sliding section 33 drives the second rotating roller 31 closer to the first rotating roller 21.

[0025] The assembly relationship between sliding section 33 and roller 5 is determined by... Figure 2 As shown, the sliding section 33 includes a connecting rod 331. One end of the connecting rod 331 is fixedly connected to the second rotating roller 31, and the other end of the connecting rod 331 is rotatably connected to the roller 5, so that when the adjusting section 32 pulls the connecting rod 331, it drives the roller 5 to move along the outer contour of the cam 42.

[0026] The specific embodiment of the adjustment section 32 is as follows: Figure 2 As shown, the adjusting section 32 includes a tension rod 321 and an airbag 322. One end of the airbag 322 is fixedly connected to the base 1, and the other end of the airbag 322 is fixedly connected to the tension rod 321. In this embodiment, an inflation device can be used to inflate or deflate the airbag 322, causing the size of the airbag 322 to change, resulting in a first position and a second position for the tension rod 321. The tension rod 321 is hinged to the sliding section 33. When the tension rod 321 is in the first position, it drives the sliding section 33 to the first position, and the roller 5 is in the first position. At this time, the large radius of the cam 42 is in contact with the roller 5, and the second rotating roller 31 is close to the first rotating roller 21. When the tension rod 321 is in the second position, it drives the sliding section 33 to the second position, and the roller 5 is also in the second position. At this time, the small radius of the cam 42 is in contact with the roller 5, and the second rotating roller 31 is away from the first rotating roller 21, ensuring the accuracy of the material passage gap and providing users with a good product experience.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
