Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment, specifically to a self-adjusting follow-up die-cutting equipment based on the tilt angle of the object being cut. Background Technology

[0002] In existing technologies, when cutting objects using die-cutting equipment, the objects often become skewed due to factors such as conveyor belt deviation, changes in material tension, or external interference. If the skew is not identified in time before cutting, the die-cutting carriage will cut the objects according to the set cutting program, resulting in the scrapping of the objects and affecting production quality and efficiency.

[0003] To address this issue, manual identification of each product directly impacts cutting efficiency and can lead to visual fatigue, resulting in inconsistent cutting of products in the same batch. Therefore, this invention proposes a self-adjusting follow-up die-cutting device based on the tilt angle of the object being cut, thereby solving the problems of product scrapping and low cutting efficiency caused by the tilt of the object. Utility Model Content

[0004] The purpose of this invention is to solve the above problems by proposing a self-adjusting follow-up die-cutting device based on the tilt angle of the object being cut.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-adjusting follow-up die-cutting device based on the tilt angle of the object being cut, comprising a frame, an angle-adjustable crossbeam assembly mounted on the frame, and several movably mounted die-cutting trolleys on the crossbeam assembly; characterized in that it further comprises a rotating shaft mounted on the frame and rotatably connected to the crossbeam assembly, and an adjustment mechanism mounted on one side of the frame 1, which drives the crossbeam assembly to rotate around the rotating shaft as a base point to adjust the tilt angle of the crossbeam assembly. The adjustment mechanism comprises a driver, a transmission component driven by the driver, and an adjustment structure that drives the crossbeam assembly to adjust the tilt angle based on the rotating shaft.

[0006] More preferably, it also includes a rotating shaft fixing block mounted on the stand for fixing the rotating shaft, and a connecting piece disposed on one side of the crossbeam assembly and rotatably connected to the rotating shaft.

[0007] Further preferably, it also includes a bias sensor baffle mounted on the transmission component and a sensor mounted on the test bench.

[0008] More preferably, the transmission component includes a ball screw that is connected to the drive unit, a ball nut that is movably mounted on the ball screw and moves linearly on the ball screw, and a linkage component that is connected to the ball nut and is used to drive the alignment structure to move and thus push the crossbeam assembly to move.

[0009] A further preferred embodiment includes a rotating pull plate mounted on the crossbeam assembly, wherein the crossbeam assembly or the rotating pull plate is provided with a waist-shaped groove adapted to the adjustment structure.

[0010] A further preferred embodiment includes a bearing column disposed on the linkage component.

[0011] Further preferably, it also includes a bearing mounted on the bearing column to reduce the friction between the alignment structure and the rotating pull plate or between the alignment structure and the crossbeam assembly.

[0012] A further preferred embodiment includes a number of guide wheels mounted on the platform to limit and guide the movement of the crossbeam assembly, and guide components mounted on the crossbeam assembly to cooperate with the guide wheels.

[0013] More preferably, the beam assembly includes a beam, several motors mounted on a connector on one side of the beam, a tensioning wheel on the other side of the beam, and a synchronous belt that is connected to the motors and tensioning wheel and fixedly connected to the die-cutting carriage to drive the die-cutting carriage to move on the beam. It also includes a tensioning seat installed on one side of the crossbeam, a tensioning shaft movably installed on the tensioning seat and used for movably installing the tensioning wheel, and a screw installed on the tensioning seat and connected to the tensioning shaft for adjusting the position of the tensioning wheel and thus adjusting the tension of the timing belt. The tensioning seat is provided with a guide groove that limits and guides the tensioning shaft. It also includes a detector connected to the die-cutting carriage, the detector being equipped with an image acquisition device.

[0014] A control method for a self-adjusting follow-up die-cutting device based on the tilt angle of the object being cut, characterized in that: it further includes a controller installed within the die-cutting device for controlling the entire die-cutting device, and the control method is as follows: a. The movement of the die-cutting carriage connected to the detector is controlled by the controller; b. During the movement, the detector controls the image acquisition device through the controller to detect the boundary points of the object being cut and identify the QR code on the object being cut. The controller archives the coordinates of the detected boundary points. c. The controller retrieves the cutting program from its database based on the recognized QR code, and compares the boundary point of the object to be cut in the cutting program with the measured boundary point to determine whether the object to be cut is skewed. d. If there is no skew, the controller controls the die-cutting carriage to cut the workpiece according to the set cutting program; e. If there is a deviation, the deviation amount is obtained by comparing the boundary point of the object being cut with the measured boundary point in the cutting process. f. The controller starts the driver according to the skew amount. The driver drives the ball screw to rotate the corresponding number of revolutions, which in turn moves the skew adjustment structure by the corresponding skew amount. g. The alignment structure pushes the crossbeam assembly to rotate by a corresponding angle based on the rotation axis, so that the crossbeam assembly is parallel to the object being cut; h. The controller controls the die-cutting carriage to cut the workpiece according to the set cutting program.

[0015] The beneficial effects of this utility model are as follows: By setting up the deviation adjustment mechanism, the angle of the crossbeam is adjusted according to the deviation state of the object to be cut before the cutting operation. Thus, the crossbeam and the object to be cut are in a parallel state without the need to adjust the angle position of the object to be cut, thereby achieving the purpose of deviation correction. This allows the die-cutting carriage to accurately cut the object to be cut, avoiding the problem that the crossbeam and the object to be cut will tilt due to the deviation of the object to be cut, which would prevent the die-cutting carriage on the crossbeam from accurately cutting the object to be cut, causing the object to be scrapped, resulting in waste and low production efficiency.

[0018] The self-adjusting follow-up die-cutting equipment based on the tilt angle of the object being cut, as described in this utility model, will now be further described with reference to the accompanying drawings.

[0019] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can also mean a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] See Figures 1-6 As shown, the self-adjusting follow-up die-cutting equipment based on the tilt angle of the object being cut includes a frame 1, an angle-adjustable beam assembly mounted on the frame 1, and several die-cutting trolleys 2 movably mounted on the beam assembly; characterized in that it also includes a rotating shaft 14 mounted on the frame and rotatably connected to the beam assembly, and an adjustment mechanism mounted on one side of the frame 1, which drives the beam assembly to rotate around the rotating shaft 14 as a base point to adjust the tilt angle of the beam assembly. The adjustment mechanism includes a driver 3, a transmission component 4 driven by the driver 3, and an adjustment structure 5 driven by the transmission component 4 to drive the beam assembly to adjust the tilt angle based on the rotating shaft 14. By setting up the deviation adjustment mechanism, the angle of the crossbeam 7 is adjusted according to the deviation state of the object to be cut before the cutting operation. This allows the crossbeam 7 to be parallel to the object to be cut without adjusting the angle position of the object, thus achieving the purpose of deviation correction. This enables the die-cutting carriage 2 to cut the object accurately, avoiding the problem that the crossbeam 7 and the object to be cut will tilt due to the deviation of the object, which would prevent the die-cutting carriage 2 on the crossbeam 7 from cutting accurately, causing the object to be scrapped, resulting in waste and low production efficiency. When adjusting the crossbeam assembly: by starting the driver 3, the driver 3 drives the transmission component 4 to move, and the transmission component 4 drives the adjustment structure 5 to move linearly. During the linear movement, the adjustment structure 5 pushes the crossbeam assembly to move linearly, and the other side of the crossbeam assembly deflects based on the rotation axis 14 as the base point.

[0022] It also includes a rotating shaft fixing block 13 mounted on the frame 1 for fixing the rotating shaft 14, and a connector 15 disposed on one side of the crossbeam assembly and rotatably connected to the rotating shaft 14; One side of the crossbeam assembly is rotatably connected to the rotating shaft 14 via a connector 15, allowing the crossbeam assembly to rotate based on the rotating shaft 14 as a base point to adjust the angle position of the crossbeam assembly.

[0023] In one embodiment, the transmission component 4 includes a ball screw 41 that is connected to the driver 3, a ball nut 42 that is movably mounted on the ball screw 41, and a linkage component 43 that is connected to the ball nut 42 and is used to install the alignment structure 5. The driver 3 can be a motor. When the driver 3 is started, the driver 3 drives the ball screw 41 to rotate. During the rotation, the ball screw 41 drives the ball nut 42 to move linearly on the ball screw 41 through the cooperation between the ball screw 41 and the ball nut 42. The ball nut 42 then drives the linkage 43 and the adjustment structure 5 to move linearly.

[0024] In one embodiment, it also includes a rotating pull plate 6 mounted on the crossbeam assembly, and the crossbeam assembly or the rotating pull plate 6 is provided with a waist-shaped groove 61 adapted to the adjustment structure 5. During the process of being pushed, the waist-shaped groove 61 of the rotating pull plate 6 or the crossbeam assembly moves based on the adjustment structure 5, and the rotating pull plate 6 drives the crossbeam assembly to deflect based on the rotation axis 14 as the base point; the waist-shaped groove 61 plays a guiding and limiting role in the rotation of the rotating pull plate 6 or the crossbeam assembly, while avoiding interference with the adjustment structure 5.

[0025] In one embodiment, the alignment structure 5 includes a bearing column 51 disposed on the linkage 43; It can be directly connected to the rotating pull plate or crossbeam assembly via the bearing column, and the rotating pull plate or crossbeam assembly can be driven by the bearing column.

[0026] In one embodiment, a bearing 52 mounted on the bearing column 51 is also included to reduce the friction between the alignment structure 5 and the rotating pull plate 6 or between the alignment structure 5 and the crossbeam assembly. By setting the bearing 52, the friction between the adjustment structure 5 and the rotating pull plate 6 or the crossbeam assembly is reduced during the operation of the adjustment structure 5, thereby improving smoothness.

[0027] In one embodiment, it further includes a plurality of guide wheels 11 disposed on the platform 1 to limit and guide the movement of the crossbeam assembly, and a guide member 12 mounted on the crossbeam assembly and cooperating with the plurality of guide wheels 11. By setting the guide wheel 11 and guide component 12, the crossbeam assembly is supported on one side and its movement is limited and guided. The guide wheel 11 also reduces resistance.

[0028] In one embodiment, the beam assembly includes a beam 7, a plurality of motors 71 mounted on a connector 15 on one side of the beam 7, a tensioning wheel 72 disposed on the other side of the beam 7, and a synchronous belt 73 that is connected to the motors 71 and the tensioning wheel 72 and is fixedly connected to the die-cutting carriage 2 to drive the die-cutting carriage 2 to move on the beam 7. When the die-cutting carriage 2 moves laterally on the crossbeam 7, the motor 71 is started, and the motor 71 drives the synchronous belt 73 to move, which in turn drives the die-cutting carriage 2 to move laterally on the crossbeam 7.

[0029] In one embodiment, it further includes a tensioning seat 74 installed on one side of the crossbeam 7, a tensioning shaft 75 movably installed on the tensioning seat 74 and used to movably install the tensioning wheel 72, and a screw 76 installed on the tensioning seat 74 and connected to the tensioning shaft 75 for adjusting the position of the tensioning wheel 72 to adjust the tension of the timing belt 73. The tensioning seat 74 is provided with a guide groove 77 that limits and guides the tensioning shaft 75. The tension shaft 75 and screw 76 are used to adjust the tension of the synchronous belt 73. During adjustment, the screw 76, which is threadedly connected to the tension shaft 75, is rotated. When the tail end of the screw 76 presses against the tension seat 74, rotating the screw 76 causes the tension shaft 75 to move along the guide groove 77 through the threaded engagement with the tension shaft 75. The tension shaft 75 then drives the tension wheel 72 to move accordingly, thereby adjusting the tension of the synchronous belt 73. The guide groove 77 serves to limit and guide the movement of the tension shaft 75 on the tension seat 74.

[0030] In one embodiment, a detector 8 connected to the die-cutting carriage 2 is also included, the detector 8 being equipped with an image acquisition device 81; the image acquisition device 81 is configured to capture images of the surface of the object being cut and transmit them to the controller of the die-cutting equipment.

[0031] When using this utility model: First, the controller in the die-cutting equipment starts the motor 71, which drives the die-cutting carriage 2 connected to the detector 8 to move laterally along the crossbeam 7. At the same time, the drive device in the die-cutting equipment is controlled to drive the crossbeam assembly to move on the die-cutting equipment. During the movement, the detector controls the image acquisition device through the controller to detect the boundary points of the object being cut and to identify the QR code on the object being cut. The controller archives the coordinates of the detected boundary points. The controller retrieves the cutting program from its database based on the recognized QR code, and compares the boundary point of the object to be cut in the cutting program with the measured boundary point to determine whether the object to be cut is skewed. If there is no skew, the controller controls the die-cutting carriage to cut the object according to the set cutting program; If a deviation exists, the boundary point of the object being cut in the cutting process is compared with the measured boundary point to determine the deviation amount; the controller then controls the adjustment mechanism to adjust the deflection angle of the crossbeam assembly based on the deviation amount. When adjusting the angle position of the crossbeam assembly, the controller controls the start of the driver 3, which drives the ball screw 41 to rotate. During the rotation, the ball screw 41 drives the ball nut 42 to move linearly through the cooperation between the ball screw 41 and the ball nut 42. The ball nut 42 then drives the linkage 43 and the adjustment structure 5 to move linearly. During the linear movement, the adjustment structure 5 pushes the rotating pull plate 6 to move linearly. During the pushing process, the waist groove 61 of the rotating pull plate 6 moves based on the adjustment structure 5. The rotating pull plate 6 drives the crossbeam assembly to deflect at the corresponding angle based on the rotation axis 14, so that the crossbeam assembly is parallel to the object being cut. The number of rotations of the ball screw 41 is controlled according to the displacement. The displacement of the ball nut 42 driven by the ball screw 41 for each rotation is measured in advance and set in the controller.

[0032] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
