DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] See also Figure 1-Figure 5 In the embodiment of the utility model, a flattening structure of a flat die-cutting machine includes a base 1 and a flattening structure. A hydraulic cylinder 7 is provided on the front and rear sides above the base 1. A moving mechanism for driving the flattening structure to move left and right is symmetrically provided above the output ends of the front and rear hydraulic cylinders 7. A flattening structure for flattening packaging materials and symmetrical left and right is provided between the front and rear symmetrical moving structures. The output end of the hydraulic cylinder 7 works to lower the flattening structure to a suitable position to press the packaging material.

[0024] The moving structure includes a slide 2, a bidirectional screw 3 is passed through the slide 2, half of the bidirectional screw 3 is provided with a right-handed thread and the other half is provided with a left-handed thread, a first moving block 5 is provided on the right-handed thread and is matched and connected with the thread of the right-handed thread, a second moving block 8 is provided on the left-handed thread and is matched and connected with the thread of the left-handed thread, and a motor 4 for driving the bidirectional screw 3 is provided at the right end of the slide 2. The first moving block 5 and the second moving block 8 are respectively matched and connected with the left and right threads, so that when the motor 4 drives the bidirectional screw 3 to rotate, the first slider and the second slider can simultaneously perform linear motion on the bidirectional screw 3.

[0025] A connecting frame 6 is provided between the first moving blocks 5 and the second moving blocks on the bilaterally symmetrical moving structure, and a flattening structure is provided below the connecting frame 6 .

[0026] The flattening structure includes a first connecting rod 16 arranged at the lower left side of the adjustment frame 9, a sleeve 13 is fixedly connected to the first connecting rod 16, a rotating shaft 15 is rotatably connected inside the sleeve 13, a flattening frame 14 is arranged on the rotating shaft 15, and a steering engine 12 for driving the rotating shaft 15 to rotate is arranged at one end of the rotating shaft 15, and a second connecting rod 17 is arranged at the lower right side of the adjustment frame 9, a supporting frame 10 is arranged on the second connecting rod 17, and a flattening roller 11 is rotatably connected to the supporting frame 10. The steering engine 12 drives the rotating shaft 15 to rotate and turn the side of the flattening frame 14 with the pressing block to the horizontal, and moves to the edge of the packaging material left and right through the moving structure to flatten the curling edge. The cross section of the flattening frame 14 is trapezoidal, and the edge of the flattening frame 14 is acute.

[0027] The flattening frame 14 rotates with the rotating shaft 15 to press the packaging material, and a smooth pressing block is provided on one side of the packaging material. The surface of the packaging material is mostly smooth, so as to avoid pulling and deforming the packaging material and flatten the curling edge.

[0028] Example 2

[0029] The outside of the leveling roller 11 is evenly distributed with heating rods 18, and the outside of the heating rods 18 is covered with a wear-resistant heat-conducting shell 19. When the leveling roller 11 rolls, the heating rods 18 work through the wear-resistant heat-conducting shell 19 to flatten the wrinkles.

[0030] The side of the leveling frame 14 provided with the pressing block is flush with the bottom of the wear-resistant heat-conducting shell 19 when adjusted to a horizontal level.

[0031] The working principle of the utility model is as follows: when the packaging material is placed under the flattening structure, the steering gear 12 drives the rotating shaft 15 to rotate and turn the side of the flattening frame 14 with the pressure block to a horizontal position, the hydraulic cylinder 7 moves to lower the flattening structure to a suitable position to press the packaging material, and the heating rod 18 works. At this time, the motor 4 drives the bidirectional screw 3 to rotate so that the first slider and the second slider move left and right on the bidirectional screw 3 in the slide 2, and at the same time drives the flattening structure to move toward the edge of the packaging material to flatten the wrinkles of the packaging material and flatten the curling. The steering gear 12 works to adjust the flattening frame 14 to the upper side of the flattening roller 11, and the motor 4 works to make the flattening roller 11 move back and forth on the packaging material until the packaging material is flattened.
