Description

Technical Field

[0001] This invention relates to the field of ironing technology for packaging boxes and packaging films, specifically a modular hexahedral synchronous ironing device. Background Technology

[0002] To ensure the intrinsic quality of goods and enhance their appearance, manufacturers wrap them in PVC transparent film. To guarantee the quality of this packaging, heat shrinkage is used for external shaping to achieve a smooth, glossy finish and improved aesthetics. However, the methods employed are mostly mechanical, randomly ironing two parallel faces of the six-sided film; or ironing two corresponding faces in stages, often only managing to iron four sides, and some even still rely on manual ironing with a soldering iron.

[0003] Traditional random ironing involves first ironing two parallel sides of the six-sided package, then ironing the two parallel end faces. If the remaining two vertical sides need to be ironed, an additional station is required to rotate the package 90° to achieve ironing on all six sides. This method is cumbersome, requires many workstations, and has complex transmission mechanisms. The traditional method of manually ironing with a fixed soldering iron is a rather primitive one. It involves manually pressing each of the six sides of the package against the heated soldering iron in turn. This method is inefficient, has a low safety factor, and is prone to burns if not handled properly.

[0004] To address this, we provide a modular hexahedral synchronous ironing device. Summary of the Invention

[0005] The purpose of this invention is to provide a modular hexahedral synchronous ironing device that can efficiently, safely, and automatically iron all sides of a hexahedral packaging box at one time and simultaneously, and can automatically unload the material, so as to solve the problems of multiple processes, low efficiency, poor safety, and easy retention of finished products in the prior art.

[0006] The present invention can be achieved by the following technical solution: a modular hexahedral synchronous ironing device, including a guide rail base, a lifting component installed above the guide rail base, and the lifting component driving a pair of upper soldering iron plates installed at the bottom of the base at a vertical angle. Below the lifting assembly, a lower fixed soldering iron plate is fixedly installed between the two sides of the guide rail base at a certain angle. A lower flip soldering iron plate is rotatably installed on the side wall of the guide rail base on one side of the lower fixed soldering iron plate. Two end floating soldering irons are symmetrically installed on the side walls of the guide rail base above the lower fixed soldering iron plate. When the lifting assembly lowers the two upper soldering iron plates to a certain height, the linkage structure drives the lower flip soldering iron plate to rotate until it is perpendicular to the lower fixed soldering iron plate. At the same time, the linkage structure drives the two end floating soldering iron plates and the lower flip soldering iron plate to move and abut against the corresponding sides of the six-sided packaging body, thereby realizing the synchronous ironing operation of each side of the six-sided packaging body.

[0007] A further technical improvement of the present invention is that: a guide rail base plate is installed at the position adjacent to the previous work station, and side guide rails are symmetrically installed at corresponding positions on both sides of the guide rail base, thereby forming an input channel to guide the six-sided package into the ironing work station, and the working surface of the guide rail base plate is provided with a V-shaped pattern.

[0008] A further technical improvement of the present invention is that: the lifting assembly includes a lifting plate that can move up and down, a reciprocating bearing member is fixed on the top of the lifting plate, the top of the reciprocating bearing member is fixed to the nut of the screw drive assembly by a connecting rod, and the connecting rod is guided by a slide rail slider; The bottom of the lifting plate is symmetrically hinged with two L-shaped hinge plates, and the two upper soldering iron plates are fixed to the two L-shaped hinge plates and are naturally in a vertical state.

[0009] A further technical improvement of the present invention is that: the lead screw transmission assembly includes a transmission lead screw that is vertically rotatably mounted to the frame via a bearing seat; protective arc plates are symmetrically arranged at the bottom of the bearing seat; a mounting plate for mounting the bearing is fixed together at the bottom of the two protective arc plates; the bottom end of the transmission lead screw is fixed to the inner ring of the corresponding bearing; a gap is provided between the two protective arc plates to allow the connecting rod to pass through; and the top of the transmission lead screw is fixed to the motor output end via a coupling.

[0010] A further technical improvement of the present invention is that the linkage mechanism includes two fan-shaped flip arms that are coaxially fixed with the lower flip soldering iron plate, and each fan-shaped flip arm and the lifting plate are provided with a transmission link whose ends are respectively hinged to both of them; The end floating soldering iron plate is slidably connected to the side wall of the guide rail base through a floating pin and a compression spring. A pressing pin is fixed in the center of the end floating soldering iron plate, and the pressing pin abuts against the wedge-shaped surface of the clamping brake block fixed inside the fan-shaped flipping arm.

[0011] A further technical improvement of the present invention is that: the top of the L-shaped hinge plate is symmetrically provided with positioning bosses, and the lifting plate is threadedly connected with positioning pins. By adjusting the extension length of the positioning pins and abutting against the positioning bosses, the angle and posture of the L-shaped hinge plate can be adjusted and fixed.

[0012] A further technical improvement of the present invention is that a lever is fixed on the side of the lower flip soldering iron plate near the lower fixed soldering iron plate, and the top of the lever is higher than the working surface of the lower flip soldering iron plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention achieves simultaneous ironing of all six sides of a six-sided package by using a lifting plate driven by the same servo motor and two vertically aligned upper soldering iron plates on the lifting plate. A linkage mechanism converts the linear motion of the lifting plate into the rotational motion of the lower rotating soldering iron plates and the horizontal linear motion of the two end floating soldering iron plates. Compared to existing technologies that require multiple steps, processes, or additional flipping stations, this invention significantly simplifies the process, reduces station occupancy, simplifies the transmission structure, and improves ironing efficiency.

[0014] 2. The present invention has a lever fixed on the lower flipping soldering iron plate. After ironing is completed, the lower flipping soldering iron plate rotates in the opposite direction under the drive of the linkage mechanism. The lever can lift the ironed six-sided package and make it suspended in the air. The package slides into the output channel by its own weight, realizing the automatic emptying function of the finished product, effectively preventing product retention, and further improving the automation level of the device.

[0015] 3. By setting a positioning pin that cooperates with the positioning boss on the L-shaped hinge plate, the present invention can finely adjust and fix the angle and posture of the two upper soldering iron plates, thereby accurately matching the posture of the six-sided packaged body entering the synchronous ironing station, ensuring the ironing fit and uniformity, and improving the ironing quality.

[0016] 4. By setting up a floating pin, a compression spring, and a pressing pin in conjunction with a clamping brake block, the floating soldering iron plate at the end can adaptively adjust its position within a certain range. This ensures reliable ironing pressure on the six-sided packaging surface while avoiding damage to the packaging or equipment caused by rigid contact, thus providing good buffering and protection.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0021] Please see Figure 1-5 As shown, a modular six-sided synchronous ironing device includes a guide rail base 1, on which a guide rail textured plate 2 is installed. The guide rail textured plate 2 is connected to the upstream processing station, and the working surface is uniformly provided with V-shaped textures to reduce the friction between the PVC packaging film covering the six-sided packaging and the channel, preventing scratches on the appearance. Side guide rails 3 are symmetrically installed on both sides of the guide rail base 1 to bind and guide the six-sided packaging to smoothly enter the synchronous ironing station. Side support plates 4 are vertically fixed on both sides of the top of the guide rail base 1. A top plate 5 is fixed between the tops of the two side support plates 4. A servo motor 6 is fixedly installed in the middle of the top plate 5. The output end of the servo motor 6 passes through the top plate 5 and is coaxially connected to one end of the transmission screw 9 through the coupling 8. The top end of the transmission screw 9 is axially fixed through the bearing seat 7 fixed to the bottom of the top plate 5. The outer circumference of the transmission screw 9 is threaded with a screw nut 13. A connecting rod 12 is fixed on the outer circumference of the screw nut 13. Slider blocks are fixed on both sides of the connecting rod 12 and are connected to the slide rail installed on the side wall of the side support plate 4 for lifting and lowering through the sliders. A reciprocating bearing seat 11 is provided on the outside of the lead screw nut 13. The connecting rod 12 passes through the reciprocating bearing seat 11 and is fixedly connected to the reciprocating bearing seat 11. An installation plate is slidably installed inside the reciprocating bearing seat 11. A bearing is provided in the middle of the installation plate. The bottom of the transmission lead screw 9 is axially limited by the bearing. Two protective arc plates 10 are symmetrically arranged between the installation plate and the bearing seat 7. The two ends of the two anti-slip plates 10 are fixedly connected to the bearing seat 7 and the installation plate respectively. A gap is left between the two protective arc plates 10 to allow the connecting rod 12 to move up and down. A lifting plate 14 is fixedly installed below the reciprocating bearing seat 11. L-shaped hinge plates 15 are symmetrically arranged on both sides below the lifting plate 14. The L-shaped hinge plates 15 are rotatably installed by hinge blocks 16 fixed to the bottom of the lifting plate 14. Two upper soldering iron plates 18 are fixed between the two L-shaped hinge plates 15, and the two upper soldering iron plates 18 are perpendicular to each other. Each L-shaped hinge plate 15 has a symmetrical positioning boss on its top. The corresponding position of the lifting plate 14 is threaded with a positioning pin 17. By adjusting the extension length of the two positioning pins 17 and abutting against the corresponding positioning boss, the angle and posture of the L-shaped hinge plate 15 can be finely adjusted and fixed, thereby matching the posture of the six-sided packaged body entering the synchronous ironing station.

[0022] A lower fixed soldering iron plate 19 is fixed at a certain angle at the end of the guide rail base 1 located on the guide rail base plate 2. Two end floating soldering iron plates 24 are symmetrically arranged on both sides above the lower fixed soldering iron plate 19. A lower flip soldering iron plate 20 is rotatably connected to the side wall of the guide rail base 1 on one side of the lower fixed soldering iron plate 19. The soldering iron plate group on the guide rail base 1 forms a synchronous ironing station. When the two upper soldering iron plates 18 descend, the two end floating soldering iron plates 24 and the lower flip soldering iron plate 20 are driven to move and abut against the corresponding sides of the six-sided packaging body through the linkage mechanism so as to realize synchronous ironing operation.

[0023] The linkage structure includes a fan-shaped flipping arm 22 that is coaxially fixed with the lower flipping soldering iron plate 20. One end of the fan-shaped flipping arm 22 is connected to the lifting plate 14 by a transmission link 23. The two ends of the transmission link 23 are respectively hinged to the fan-shaped flipping arm 22 and the lifting plate 14. The end floating soldering iron plate 24 is slidably connected to the side wall of the guide rail base 1 by multiple floating pins 25, and each floating pin 25 is coaxially provided with a compression spring 26 on its outer periphery. The two ends of the compression spring 26 abut against the end protrusions of the guide rail base 1 and the floating pin 25, respectively, so that the end floating soldering iron plate 24 tends to move away from the inner side wall of the guide rail base 1. The center of the end floating soldering iron plate 24 is fixed with a pressing pin 27 that penetrates the side wall of the guide rail base 1, which abuts against and cooperates with the clamping brake block 28 fixed inside the fan-shaped flip arm 22. Since the clamping brake block 28 is a wedge-shaped structure, during the rotation of the fan-shaped flip arm 22, the clamping brake block 28 and the pressing pin 27 cooperate to adjust the distance between the end floating soldering iron plate 24 and the side wall of the guide rail base 1.

[0024] More specifically, a lever 21 is fixed to the side wall of the lower flip soldering iron plate 20 near the lower fixed soldering iron plate 19. The top of the lever 21 is a certain distance higher than the working surface of the lower flip soldering iron plate 20, generally set to 2mm, so that after the packaging body is ironed on all six sides, the lever 21 tilts and flips the ironed packaging body along with the lower flip soldering iron plate 20 at the same time as the lower flip soldering iron plate 20 rotates. At this time, the packaging body is in a suspended state and slides into the output channel by its own weight, thereby realizing the function of automatic emptying to prevent the finished product from being stuck.

[0025] Based on the above device structure, when the servo motor 6 drives the transmission screw 9 to rotate through the coupling 8, the connecting rod 12 fixed to the screw nut 13 moves up and down reciprocally, and the reciprocating bearing 11 fixed to the connecting rod 12 moves back and forth accordingly, thereby driving the two upper soldering iron plates 18 below it to move up and down at a vertical angle. Simultaneously, during the up-and-down movement of the lifting plate 14, the transmission linkage 23 drives the fan-shaped flipping arm 22 to rotate, thereby driving the lower flipping soldering plate 20, which is coaxially fixed with it, to flip. When the fan-shaped flipping arm 22 rotates, the clamping brake block 28 fixed on its inner side cooperates with the squeezing pin 27 to adjust the distance between the two end floating soldering plates 24. When the lifting plate 14 descends (or rises) to a certain height, the fan-shaped flipping arm 22 rotates 90 degrees in the forward (or reverse) direction, thereby driving the lower flipping soldering plate 20 to flip 90 degrees to be in contact with the six-sided packaging body (or to form an output slide relative to the six-sided packaging body). At the same time, it drives the two end floating soldering plates 24 to move closer to each other and (or move away from each other) the six-sided packaging body to achieve synchronous ironing operation (or to achieve unloading).

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
