[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0041] The present invention provides a linkage defoaming device, such as Figure 1-Figure 3As shown, it includes a debubbling station arranged on the machine plane of the frame 900, and a plurality of debubbling actuators 100 are arranged around the debubbling station. This embodiment is described by a debubbling device of a rectangular box body. Four debubbling actuators 100 are arranged around the debubbling station to form a rectangle matching the rectangular box body. The debubbling extrusion surface of the debubbling actuator 100 is parallel to one side of the corresponding box body. It should be understood that the number, installation position and shape of the debubbling surface of the debubbling actuator 100 should be adapted to the box body shape of the work object. A plurality of slideways are arranged on the frame 900 corresponding to the plurality of debubbling actuators 100, and the debubbling actuators 100 are slidably connected to the frame 900 through the slideways so that the debubbling actuators 100 can move along the slideways. A plurality of lever mechanisms 200 are provided on the frame 900 corresponding to each debubble execution component 100. The lever mechanism 200 is rotatably connected to the frame 900 and is connected to the corresponding debubble execution component 100 on one hand and is connected to a linkage mechanism 300 on the other hand. The linkage mechanism 300 is used to drive the plurality of lever mechanisms 200 to rotate and thereby drive the debubble execution component 100 to approach or move away from the debubble station.

[0042] Specifically, Figure 2 and Figure 3 As shown, the defoaming actuator 100 includes a fork mechanism 110 fixedly arranged at the bottom thereof, and a first strip-shaped notch 111 is provided on the fork structure 100. The lever mechanism 200 includes a special-shaped lever 210. The shape of the special-shaped lever 210 in this embodiment is approximately an L-shaped rod. The middle part of the special-shaped lever 210, i.e., the L-shaped corner, is hinged on the frame 900 to form a rotating connection. The lever mechanism 200 also includes a first end 220 and a second end 230 respectively located at both ends of the special-shaped lever 210. The first end 220 and the second end 230 can adopt a shape with a circular structure such as a sphere or a cylinder but is not limited to the shape. The first end 220 is located in the first strip-shaped notch 111 and the diameter of the first end 220 matches the width of the first strip-shaped notch 111, so that the first end 220 can rotate in the first strip-shaped notch 111 and translate along the first strip-shaped notch 111, thereby driving the defoaming actuator 100 to move. Preferably, the diameter of the first end portion 220 is larger than the cross-sectional width of the special-shaped lever 210, so that the first end portion 220 can rotate at a larger angle relative to the first strip-shaped notch 111. It should be understood that matching means that the original design purpose of the two sizes is equal, but considering the error relationship or for the convenience of production, use, installation, etc., the two sizes can be close, for example, the width of the first strip-shaped notch 111 is slightly larger than the diameter of the first end portion 220.

[0043] Specifically, Figure 3As shown, the linkage mechanism 300 includes a linkage frame 330 and a plurality of first guide posts 340, the axis of the first guide posts 340 is parallel to the direction of gravity and is fixedly connected to the frame, the linkage frame 330 is slidably arranged on the plurality of first guide posts 340, and can be lifted and lowered along the first guide posts 340, the linkage frame 330 is provided with a plurality of second strip-shaped notches 301 corresponding to the plurality of lever mechanisms 200, the second end 230 of the lever mechanism 200 is located in the second strip-shaped notch 301 and the diameter of the second end 230 matches the width of the second strip-shaped notch 301, preferably, the diameter of the second end 230 is greater than the cross-sectional width of the special-shaped lever 210, so that the rotation angle of the second end 230 relative to the second strip-shaped notch 111 is larger. It should be understood that matching means that the original design purpose of the two sizes is equal, but considering the error relationship or for the convenience of production, use, installation, etc., the two sizes can be close, for example, the width of the second strip-shaped notch 301 is slightly greater than the diameter of the second end 230.

[0044] When the linkage frame 330 moves up and down along the first guide column 340, the second strip-shaped notch 301 drives a number of special-shaped levers 210 to rotate, and then the first end 220 drives a number of fork structures 110 and the debubble execution component 100 to move closer to or away from the debubble station along the slide on the machine plane, so as to squeeze the box body for debubble removal or loosen the box body.

[0045] Preferably, the first end 220 adopts a rolling structure, including a first roller 221, and the first roller 221 is rotatably connected to the end of the special-shaped lever 210 as the first end; the second end 230 adopts a rolling structure, including a second roller 231, and the second roller 231 is rotatably connected to the end of the special-shaped lever 210 as the second end. By adopting a rolling structure for the first end 220 and the second end 230, the wear of the workpiece due to the sliding friction of the high-pair contact is reduced, and the service life of the equipment is increased.

[0046] like Figure 3 As shown, the lifting movement of the linkage frame 330 in this embodiment is described by taking the lead screw and nut mechanism as an example, but is not limited thereto. The lifting movement can also be achieved by a gear rack mechanism, a cylinder or a hydraulic cylinder.

[0047] Specifically, the linkage mechanism 300 also includes a lead screw 310, a first nut 320, a first power source 350 and a first mounting frame 360. The lead screw 310 passes through the linkage frame 330, and the extension line of its axis passes through the debubbling station and is parallel to the axis of the first guide column 340. The remaining mechanisms are symmetrically distributed around the lead screw 310, which is convenient for production assembly and use control. On the one hand, the first nut 320 is spirally connected with the lead screw 310 to form a lead screw nut pair, and on the other hand, it is fixedly connected with the linkage frame 330 along the axis direction of the lead screw 310, so that when the first nut 320 moves spirally on the lead screw 310, it can drive the linkage frame 330 to move along the axis direction of the lead screw 310 with the first nut 320, that is, to perform lifting and lowering movements. The first power source 350 is one of the rotating power sources such as but not limited to a motor, a stepper motor, a servo motor or a hydraulic motor. The first power source 350 is fixed on the linkage frame 330 through the first mounting frame 360, and its output shaft is connected to the first nut 320 through but not limited to a synchronous belt or a gear transmission to drive the first nut 320 to rotate and spirally move on the lead screw 310, driving the linkage frame 330 and the first power source 350 to rise and fall simultaneously. Preferably, a rolling body is provided between the first nut 320 and the lead screw 310, forming, for example, a roller screw nut mechanism to reduce the friction loss of the lead screw.

[0048] Preferably, if Figure 3 and Figure 4As shown, the present embodiment also includes a support direct-acting mechanism 400, which includes a support 410, a second nut 420 and a plurality of second guide columns 430. The support 410 is rotatably connected to one end of the lead screw 310 near the defoaming station through a bearing, and is slidably connected to the frame 900 through the second guide column 430. The axis of the second guide column 430 is parallel to the axis of the lead screw 310, and the second nut 420 is fixed on the frame 900 and is spirally connected to the lead screw 310. The support direct-acting mechanism 400 also includes a second power source 440 and a second mounting frame 450. The second power source 440 adopts but is not limited to one of the rotating power sources such as a motor, a stepper motor, a servo motor or a hydraulic motor. The second power source 350 is fixed on the second mounting frame 450, and its output shaft is connected to the screw 310 through but not limited to a synchronous belt or a gear transmission mechanism to drive the screw 310 to rotate. The second mounting frame 450 is slidably arranged on the first guide column 340 and is fixedly connected to the screw 310 along the axial direction of the screw 310. When the screw 310 rotates under the drive of the second power source 440, since the second nut 420 is fixed, the screw 310 performs a spiral motion, and the support 410 moves along the sliding direction of the second guide column 430 with the screw 310 under the action of the second guide column 430, that is, the support 410 performs a lifting motion. After receiving the box body, the support table 410 moves downward to place the box body at the defoaming station, and the first power source 350 drives the linkage mechanism 300 to drive a plurality of defoaming execution components 100 to perform extrusion defoaming operations.

[0049] The present invention also provides a box production device, comprising the linkage defoaming device as described in any one of the above items.

[0050] The linkage defoaming device provided by the present invention performs defoaming operations on several surfaces of the material box by arranging several defoaming execution components around the defoaming station, and connects the several defoaming execution components with the linkage mechanism through several lever mechanisms correspondingly connected to the defoaming execution components to perform linkage control on the several defoaming execution components. Compared with the prior art, the present invention drives several defoaming execution components to act simultaneously through the linkage mechanism, and there is no need to set up power sources separately, thereby reducing the production, assembly and use costs of the equipment.

[0051] Although the terms such as defoaming actuator, fork structure, first strip notch, lever mechanism, special-shaped lever, first end, first roller, second end, second roller, linkage mechanism, second strip notch, lead screw, first nut, linkage frame, first guide column, first power source, first mounting frame, support platform direct-acting mechanism, support platform, second nut, second guide column, second power source, second mounting frame and frame are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
