Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a rotating stand device for a die-cutting machine. Background Art

[0002] Die-cutting machines are widely used in the packaging field. They are used to die-cut sheet-shaped packaging materials such as corrugated cardboard and plastic sheets according to the set size and shape for downstream processing stations. Common die-cutting machines include feeding stations, processing and die-cutting stations, and discharging stations. The processed materials are transported to each station through a conveying device, processed in each station in turn, and then sent to the downstream station after completion.

[0003] In a modular machine, depending on the arrangement of each processing station, it is often necessary to turn the conveying direction of the material to be processed, for example, by 90 degrees. For this purpose, the die-cutting machine is commonly equipped with a rotating table device. After the material to be processed is conveyed to the carrying table of the table device by conveying devices such as conveyor belts and rollers, the carrying table is driven by a motor to rotate from a first orientation to a second orientation, and then sent to the next processing station or device. At the same time, the carrying table is driven by a motor to return from the second orientation to the first orientation to receive additional material to be processed.

[0004] However, in the die-cutting machine that uses a motor to drive the carrier, the motor and its mounting structure include multiple mechanical and electronic components, which require regular maintenance and servicing to ensure their normal operation, thereby increasing the maintenance cost and workload of the system, and due to the limitations of the mounting structure, the maintenance and servicing operation of the existing mechanism for rotating the carrier is not convenient. On the other hand, the motor-driven rotating table requires continuous consumption of electrical energy to achieve rotation, which may result in high energy consumption, especially in large-scale or continuous operation.

[0005] Therefore, it is expected to improve the rotating table in the existing die-cutting machine to reduce the manufacturing and maintenance costs, and also to make the operation more reliable and the energy consumption lower. Utility Model Content

[0049] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0050] In the following description, “axial direction” refers to the direction along the rotation axis A of the rotating gantry 20, and “radial direction” refers to the direction relative to the rotation axis A of the rotating gantry 20 (see Figure 4 ) in the radial direction, unless otherwise specified.

[0051] like Figure 1 and Figure 2 As shown, the rotating platform device 1 according to the present invention mainly includes a base 10 and a rotating platform 20, and the base 10 and the rotating platform 20 can rotate relative to each other within a set rotation range. The base 10 is the fixed part of the rotating platform device, and the rotating platform 20 is the rotating part of the rotating platform device, that is, the base 10 is stationary, and the rotating platform 20 rotates relative to the base 10 around the rotation axis A.

[0052] In a preferred embodiment, the rotating platform 20 can be rotated to the following two positions and stop at these two positions: Figure 1 The first orientation shown may also be referred to as the 0° position, and Figure 2 The second orientation shown may also be referred to as the 90° position. That is, the rotation range of the rotating table device 1 of the preferred embodiment is 90 degrees, and the processed material carried on the device 1 can rotate 90 degrees from the first orientation to the second orientation along with the rotating table 20. It should be understood that the angle between the two static positions may also be determined to be other angles according to the requirements of the use scenario. Alternatively, in other alternative embodiments, the rotating table 20 may have three static positions, for example, a 0° position, a +90° position, and a -90° position.

[0053] In a preferred embodiment, if Figure 1 - Figure 4 As shown, the rotating platform 20 mainly includes a side frame 21, a bottom plate 22 located at the lower side of the side frame 21, and a panel 24 located at the upper side of the side frame 21. The bottom plate 22 and the panel 24 are arranged substantially in parallel and are separated from each other by a distance by means of the side frame 21. One side of the panel 24 is usually used to carry the processed sheet, such as cardboard or other material sheets, directly or through other trays or supporting members. Figure 4As shown, the bottom plate 22, the panel 24 and the side frame 21 form a receiving chamber of the rotating platform 20. In a preferred embodiment, the receiving chamber 25 of the rotating platform 20 is in the shape of a flat rectangular parallelepiped, and the components of the rotating actuator 50 and the components of the rotating support assembly 60 are accommodated in the space of the receiving chamber 25, which will be further described below.

[0054] Figure 3 A schematic diagram of a rotary actuator 50 according to a preferred embodiment is shown, and the panel 24 of the rotating stage device 1 is removed to clearly show the specific structure of the rotary actuator 50. The rotary actuator 50 is configured to provide a rotary driving force for the rotating stage 20 so that the rotating stage 20 rotates relative to the base 10 with the rotation axis A as the center.

[0055] Specifically, the rotary actuator 50 mainly includes an actuating cylinder 51 and a mutually meshing gear portion 52 and a rack portion 53. The actuating cylinder 51, also commonly referred to as a pneumatic cylinder or a pneumatic actuator, uses compressed air to move a load along a linear path. The actuating cylinder 51 includes a cylinder body 511 and a telescopic rod 512, one end of the telescopic rod 512 having a piston (not shown) located in the cylinder body 511 and moving with the pressure change in the cylinder 51. When the actuating cylinder 51 receives a start or excitation signal, the telescopic rod 512 of the actuating cylinder 51 can extend or contract relative to the cylinder body 511 to provide an actuating force, so that the gear portion 52 and the rack portion 53 that mesh with each other move relative to each other. Preferably, the actuating cylinder 51 can be a double-acting cylinder to controllably and accurately extend and retract the telescopic rod.

[0056] Furthermore, if Figure 2 As shown, the gear portion 52 is fixedly mounted on the base 10. In order to allow the rotating platform 20 to rotate 90 degrees, the embodiment of the present application is provided with a gear portion 52 of a 90-degree arc segment. It should be understood that the arc of the arc segment of the gear portion 52 can be set according to the set rotation range, but a full circle of gears can also be set along the outer surface of the base 10. In other alternative embodiments, the gear portion 52 can also be an integral part of the base 10.

[0057] like Figure 4 As shown, a circular opening 23 is provided in the middle of the bottom plate 21, and the base 10 protrudes upward through the opening 23 into the accommodating cavity 25 of the rotating platform 20. The base 10 has a cylindrical outer surface, and a step portion 110 is formed on the cylindrical outer surface. The step portion 110 has a horizontal surface 113 perpendicular to the rotation axis A and a vertical surface 112 parallel to the rotation axis A. The gear portion 52 is matched to the step portion 110, and the two are fixed by a plurality of fasteners. The two surfaces of the gear portion 52 respectively abut against the horizontal surface 113 and the vertical surface 112 of the step portion 110 to accurately position the gear portion 52.

[0058] On the other hand, the rack portion 53 is attached to the telescopic rod 512 of the actuating cylinder 51 to move with the extension and retraction of the telescopic rod 512. Preferably, the rack portion 53 is mounted on a slider, and the slider can be matched to the guide member 54 and can slide linearly along the guide member 54. In a preferred embodiment, the guide member 54 is a straight slide rail fixed on the surface of the bottom plate 22 along the rotating stage 20. It is advantageous to install the slide rail along the surface of the bottom plate 22, which can provide a smooth movement of the rack portion 53 on the one hand, and make the overall structure of the rotary actuator more compact on the other hand.

[0059] Preferably, two sliders are provided to carry the rack portion 53, and the two sliders are arranged at a distance from each other, so that one end of the rack portion 53 is mounted on one slider, and the other end of the rack portion 53 is mounted on the other slider. In this way, the rack portion 53 moves along the guide member 54 by means of the two sliders.

[0060] In order to facilitate maintenance and repair of the rotary actuator 50, preferably, a plurality of hollow portions are provided on the panel 25 to expose multiple portions of the rotary actuator 50 below. Figure 4 As shown, the hollow portion is configured to expose both ends of the actuating cylinder 51, and at the same time, also expose the portion where the teeth of the rack portion 53 and the teeth of the gear portion 52 mesh with each other.

[0061] The travel of the rack portion 53 can be limited by the limiter 30 fixed to the bottom plate 22 or the side frame 21 of the rotating platform 20. In some alternative embodiments, the limiter 30 can also be fixed to the guide member. Figure 2 As shown, preferably, the two limiters 30 are respectively fixed to the side frames 21 of the rotating gantry 20, and when the rotating gantry 20 is in the first orientation, the stop surface of the limiter 30 abuts against one end of the rack portion 53, and when the rotating gantry 20 is in the second orientation, the stop surface of the limiter 30 abuts against the other end of the rack portion 53, thereby limiting the travel range of the rack portion 53 in two directions.

[0062] Preferably, the limiter 30 may also have an adjustment device, such as a threaded adjustment device, so that the limit range of the limiter 30 is adjustable, thereby fine-tuning the stroke of the rack portion 53 and correspondingly adjusting the rotation angle range of the rotating platform 20.

[0063] In a preferred embodiment, in the flat rectangular accommodating chamber 25 of the rotating platform 20, the cylinder 511 in the rotary actuator 50 is arranged adjacent to one long side of the accommodating chamber 25, and the rack portion 53 is located inside the cylinder 511 and directly adjacent to the gear portion 52. The open portion 23 of the bottom plate 22 of the rotating platform 20 is arranged approximately in the center, and the radius of the tooth surface of the arc segment gear portion 52 is preferably greater than or equal to one quarter of the length of the short side of the rectangular bottom plate 22.

[0064] In addition, the rotating platform device 1 further includes a rotating support assembly 60, which is installed in the accommodating cavity 25 of the rotating platform. In a preferred embodiment, the rotating support assembly 60 includes a thrust bearing 62 and a radial bearing 61, which respectively provide axial rotating support and radial rotating support. Preferably, the thrust bearing 62 and the radial bearing 61 are both ball bearings.

[0065] Specifically, Figure 5 As shown, the thrust bearing 62 is arranged radially inside the radial bearing 61. On one hand, the bearing ring of one side of the thrust bearing 62 is connected to the rotating gantry 20, and the bearing ring of the other side of the thrust bearing 62 is connected to the base 10; on the other hand, the bearing ring of one side of the radial bearing 61 is connected to the rotating gantry 20, and the bearing ring of the other side is connected to the base 20. In a preferred embodiment, the rotating gantry 20 is mounted to the rotating support assembly 60 from the top side, and the base 10 is fixed to the rotating support assembly 60 from the radial side and the bottom side of the rotating support assembly 60.

[0066] Based on the thrust bearing 62 and the radial bearing 61, the rotary support assembly 60 is divided into a first part and a second part that can rotate relative to each other. Figure 4 and Figure 5 As shown, the first part of the rotating support assembly 60 includes a connection plate 63 to which the panel 24 of the rotating gantry 20 is fixed from above. The second part of the rotating support assembly 60 includes a part of the base 10, or may also include a connection member attached to the base 10.

[0067] In other alternative embodiments, the rotation support assembly 60 may also include a single slewing bearing, which is a special bearing designed to support axial, radial and bending moment loads at the same time, and it can also enable rotation or slewing motion between the base 10 and the rotating platform 20.

[0068] The operating method of the rotating stage device 1 according to the present utility model is as follows.

[0069] Figure 1 The rotating stage 20 is shown in a first orientation or 0° position, with the long side of the rotating stage 20 at Figure 1 At this time, the telescopic rod 512 is retracted in the cylinder body 511, and the rack portion 53 abuts against the stopper 30 on one side of the guide member 54. As the telescopic rod 512 extends out of the cylinder body 51, the telescopic rod 512 drives the rack portion 53 to move along the guide member 54 toward the stopper 30 on the other side of the guide member 54. At the same time, the teeth of the rack portion 53 mesh with the teeth of the gear portion 52, so that the rotating platform 20 rotates 90 degrees around the base 10, and the rotating platform 20 rotates counterclockwise around the rotation axis A as shown in FIG. Figure 2The second orientation or 90° position shown is when the long side of the rotating platform 20 is arranged vertically. When the telescopic rod 512 is retracted again, the rotating platform 20 will rotate clockwise around the base 10 as shown in FIG. Figure 1 First orientation shown.

[0070] During the operation of the rotating stage device 1, all components fixedly mounted on the rotating stage 20 will rotate with the rotating stage 20, that is, the actuating cylinder 51, the rack portion 53 attached to the actuating cylinder 51, and the stopper 30 will rotate together with the rotating stage 20; while the base 10 and the gear portion 52 thereon are stationary. During the rotation of the rotating stage 20, the teeth of the rack portion 53 and the gear portion 52 are always kept in meshing.

[0071] The rotating platform device according to the utility model adopts an actuating cylinder to drive the rotation of the rotating platform, thereby reducing the manufacturing and maintenance costs of the rotating platform. When in use, the platform rotates smoothly and the energy consumption is relatively low.

[0072] Although the utility model is disclosed as above with preferred embodiments, it is not intended to limit the utility model. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the utility model. Therefore, any modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the content of the technical solution of the utility model shall fall within the protection scope defined by the claims of the utility model.
