DETAILED DESCRIPTION

[0026] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] It should be noted that if there are directional indications (such as up, down, bottom, top, etc.) involved in this embodiment, the directional indication is only used to explain the relative position relationship, movement, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0028] like Figure 1-Figure 7 As shown, a cutting device suitable for products of multiple specifications includes a supporting platform mechanism, a tool holder seat 1 and a driving module capable of driving the supporting platform mechanism to move horizontally toward the tool holder seat 1; the supporting platform mechanism includes a vacuum rotating platform 2, a vacuum platform 3 arranged on the vacuum rotating platform 2, and an outer ring supporting platform 4 sleeved on the outer periphery of the vacuum platform 3, and a gap is left between the vacuum platform 3 and the outer ring supporting platform 4, and the tool holder seat 1 is provided with several groups of pressing roller mechanisms capable of pressing down on the outer ring supporting platform 4 and the vacuum platform 3, and a cutting mechanism capable of extending into the gap from the notch 401 on the outer ring supporting platform 4.

[0029] In the above technical solution, the material to be cut into discs can be prevented from being placed on the vacuum platform 3, and the vacuum rotating platform 2 drives the vacuum platform 3 to rotate along the fixed rotating axis, and the driving module drives the vacuum rotating platform 2 to move toward the tool holder seat 1, so that the cutting mechanism can start from passing through the notch 401 on the outer ring supporting platform 4, and cooperate with the vacuum rotating platform 2 that drives the material to rotate, and the pressure roller mechanism that can press down on the surface of the material to prevent the material from jumping and deforming, to cut the material. The distance between the position where the cutting mechanism falls on the material and the position of the rotating axis of the vacuum platform 3 at this time is the outer diameter size of the material after cutting. This technical solution can adjust the specifications of the material cutting by adjusting the distance that the vacuum rotating platform 2 moves toward the tool holder, and can meet the specification cutting requirements within a certain range without changing stamping dies of different specifications. At the same time, the automatic cutting device of this technical solution can not only cut discs, but also cut elliptical material sheets.

[0030] Furthermore, in order to further increase the cutting range of the cutting device, as Figure 3As shown, a support seat 5 is provided on the vacuum rotating platform 2, and a pneumatic flexible positioner 6 is embedded on the support seat 5 and is positioned and connected with the vacuum platform 3. A pneumatic slip ring 7 is passed through the vacuum rotating platform 2, and a vacuum pipeline 8 is laid on the vacuum rotating platform 2 through the pneumatic slip ring 7. The pneumatic slip ring 7 is used as the basis for laying the pipeline, and is externally connected to a negative pressure gas source, which can effectively solve the problem of the vacuum pipeline 8 being entangled when the vacuum platform 3 rotates. At the same time, a trachea quick connector 9 is provided on the vacuum pipeline 8, and the trachea quick connector 9 can connect the pneumatic flexible positioner 6 and the vacuum platform 3. The pneumatic flexible positioner 6 cooperates with the trachea quick connector 9 to quickly complete the disassembly, installation and replacement of the vacuum platform 3, reduce the time for daily maintenance of the equipment, and provide convenience for maintenance personnel. At the same time, according to the properties of the required cutting material itself, the vacuum platform 3 of different materials can be adjusted and replaced in a targeted manner to ensure the cutting quality, and the vacuum platform 3 of different specifications can also be quickly replaced to further increase the scope of application of the device.

[0031] Furthermore, in the above technical solution, if Figure 2 As shown, the cutting mechanism includes a support plate 10 disposed on a knife holder 1, and a cutting knife 11 disposed opposite to the support plate 10. The support plate 10 can rotate freely, and the gap between the cutting knife 11 and the support plate 10 is small, which will form a certain shear force. When the material passes between the cutting knife 11 and the support plate 10, it will be cut and divided.

[0032] Furthermore, in the above technical solution, if Figure 5 , Figure 6 As shown, the roller mechanism includes a roller rod 12 and a flip assembly that can drive the roller rod 12 to flip. At the same time, since different positions have different linear speeds when the material rotates, a plurality of bearing seats 13 are movably provided on the roller rod 12, and each bearing seat 13 is provided with a plurality of rollers 14 that can rotate independently. While increasing the contact area between the roller mechanism and the material, the rollers 14 on the roller mechanism can press down on the material according to different cutting requirements to prevent the material from jumping, wrinkling, and deforming during the cutting process. At the same time, in order to prevent the roller 14 from pressing down on the material with too much force, an elastic member 15 is sleeved on the bearing seat 13, and the two ends of the elastic member 15 can be elastically abutted against the bearing seat 13 and the roller rod 12 respectively, so that the pressure of the roller 14 pressing down on the material can be adaptively adjusted, and the roller 14 can effectively prevent the roller 14 from pressing and deforming the material. In this technical solution, preferably, the elastic member 15 can be a relatively low-priced compression spring with a long service life.

[0033] Further, such as Figure 6As shown, in the present technical solution, the flip assembly can use a flip cylinder or other mechanical standard parts with a flip driving structure, and can also use a mechanical structure with a simple, practical structure and low cost. Specifically, the flip assembly includes a roller seat 16 and a driving cylinder 17. The roller seat 16 is provided with a limiting groove 1601. The roller rod 12 is L-shaped, and the bending part of the roller rod 12 can slide along the limiting groove 1601. The piston rod on the driving cylinder 17 is hinged to the end of the roller rod 12. The driving cylinder 17 can drive the bending part of the roller rod 12 to slide along the limiting groove 1601, thereby driving the roller rod 12 to flip upward, so that the roller 14 is away from the material on the vacuum platform 3, so that the vacuum rotating platform 2 and the vacuum platform 3 can carry the material to the next step.

[0034] Furthermore, in order to accurately control the displacement distance of the vacuum rotating platform 2 toward the tool holder seat 1, as Figure 1 As shown, the driving module includes a carrier 18 and a servo slide 19 arranged on the carrier 18 , and the vacuum rotating platform 2 and the pneumatic slip ring 7 are both arranged on a slide plate 20 on the servo slide 19 .

[0035] In this embodiment, in order to ensure that the cutting knife 11 can accurately cut the material, including but not limited to, the visual technology in the prior art can be used to identify the product diameter and the position of the material cutting, and cooperate with the drive module and the telescopic cylinder to accurately adjust the position of the cutting knife 11 falling on the material to increase the accuracy of material cutting.

[0036] Further, such as Figure 1 As shown, a material unloading track 21 is provided on the carrier 18, and a waste material recovery box 22 is provided at the end of the material unloading track 21. The cut materials can fall into the waste material recovery box 22 along the material unloading track 21, which is convenient for unified recycling management.

[0037] Furthermore, in order to facilitate the adjustment of the cutting angle of the cutting knife 11, as shown in FIG. Figure 1 , Figure 7 As shown, a fixing plate 23 is provided at the bottom of the tool holder seat 1, and two sets of parallel bearing connection seats 24 are hinged at the bottom of the fixing plate 23, and the two sets of bearing connection seats 24 are respectively provided on the pads 25, and the two pads 25 are connected to the same bottom plate 27 through the screw set 26. In the present technical solution, the fixing plate 23 can rotate relative to the same set of bearing connection seats 24, and the screw set 26 includes a screw, a gasket, and a nut. By increasing or decreasing the number of gaskets on the screw, the distance between the gasket 25 and the bottom plate 27 can be increased, so that the entire tool holder seat 1 is tilted at a certain angle, so as to adjust the cutting angle of the cutting knife 11.

[0038] Working principle: Before cutting, the servo slide 19 can be used to drive the vacuum rotating platform 2, vacuum platform 3, and outer ring support platform 4 to move aside, so as to facilitate the material to be spread flat on the vacuum platform 3, and then the negative pressure gas source is started to absorb the material through vacuum negative pressure. Then the servo slide 19 is used to drive the vacuum platform 3 to move toward the tool holder 1 again, and the vacuum rotating platform 2 drives the vacuum platform 3 to drive the material to rotate at a uniform speed, and the driving cylinder 17 drives the roller 14 on the pressure roller rod 12 to press down on the surface of the material, and the cutting knife 11 cooperates with the support plate 10 to cut the material. By adjusting the distance that the vacuum rotating platform 2 moves toward the tool holder, the specifications of the material cutting can be adjusted, and the cutting requirements within a certain range of specifications can be completed without replacing stamping dies of different specifications.

[0039] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model. The technical scope of this utility model is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
