During the folding operation of the blister box, the conveying mechanism 2 conveys the blister box to be folded, and the folding mechanism 4 provides a three-side folding station for the blister box. The lifting cylinder of the clamping mechanism 3 makes the heating knife on the clamping mechanism 3 vertically descend, compresses the blister box, and completes the three-side folding of the blister box.

[0043] By adopting the above technical solution, by setting the lead screw 51 and the movable seat 53, when the lead screw 51 rotates, the lead screw 51 drives the movable seat 53 to move horizontally, and the movable seat 53 causes the U-shaped fixed plate 41 and the folding bottom plate 42 to move horizontally synchronously through the cylinder 43, thereby realizing the adjustment of the distance between the two folding bottom plates 42, which is convenient for folding blister boxes of different widths.

[0044] A rotating handle 52 is fixedly mounted on one end of each of the four lead screws 51 .

[0045] By adopting the above technical solution and providing the rotating handle 52 , it is convenient for the operator to rotate the lead screw 51 .

[0046] A second guide rod 54 is fixedly mounted on the folding machine frame 1 , and two second guide blocks 55 are slidably mounted on the second guide rod 54 . One second guide block 55 is fixedly connected to a mounting base of a cylinder 43 via a mounting plate.

[0047] By adopting the above technical solution, by providing the second guide rod 54 and the second guide block 55 , the second guide block 55 enables the movable seat 53 to keep moving in the horizontal direction through the cylinder 43 .

[0048] The disassembly and assembly mechanism 6 includes four push-pull seats 61, spring rods 62 are fixedly installed on both sides of the push-pull seats 61, and a trapezoidal limit block 63 is fixedly installed on one end of the spring rod 62 away from the push-pull seat 61. Through holes 64 are provided on the two folded bottom plates 42, and two trapezoidal limit grooves 65 are provided on the inner wall of the through hole 64. The trapezoidal limit block 63 and the inner wall of the trapezoidal limit groove 65 are in active contact.

[0049] By adopting the above technical solution, by setting the push-pull seat 61, the spring rod 62, the trapezoidal limit block 63 and the trapezoidal limit groove 65, when the push-pull seat 61 moves horizontally, the push-pull seat 61 causes the trapezoidal limit block 63 to move horizontally synchronously through the spring rod 62, when the trapezoidal limit block 63 and the trapezoidal limit groove 65 are horizontally corresponding, the spring rod 62 extends, and pushes the trapezoidal limit block 63 into the trapezoidal limit groove 65, and the trapezoidal limit block 63 fixes the folded bottom plate 42 on one side of the U-shaped fixed plate 41 through the trapezoidal limit groove 65, when the push-pull seat 61 moves horizontally in the opposite direction, the push-pull seat 61 causes the trapezoidal limit block 63 to move horizontally synchronously through the spring rod 62, and the trapezoidal limit block 63 moves along the hypotenuse of the trapezoidal limit groove 65, and squeezes the spring rod 62 to contract, so that the trapezoidal limit block 63 is separated from the trapezoidal limit groove 65.

[0050] Two support plates 66 are fixedly mounted on the inner walls of the two U-shaped fixing plates 41 . A threaded rod 67 is rotatably mounted on the support plate 66 . One end of the threaded rod 67 away from the support plate 66 is rotatably connected to one side of the push-pull seat 61 .

[0051] By adopting the above technical solution, the threaded rod 67 is rotated, and the threaded rod 67 drives the push-pull seat 61 to move in the horizontal direction.

[0052] A knob 68 is fixedly installed on one end of the threaded rod 67 close to the support plate 66, and an extension plate 69 is fixedly installed on one end of the support plate 66. A slide groove 7 is opened on the extension plate 69, and a slider 71 is slidably installed on the inner wall of the slide groove 7. An L-shaped connecting plate 72 is fixedly installed on the upper surface of the slider 71. The end of the L-shaped connecting plate 72 away from the slider 71 is fixedly connected to one side of the push-pull seat 61.

[0053] By adopting the above technical solution, by setting the knob 68, when the operator manually turns the knob 68, the knob 68 causes the threaded rod 67 to rotate, and by setting the slide groove 7, the slider 71 and the L-shaped connecting plate 72, the slider 71 slides horizontally along the inner wall of the slide groove 7, and the slider 71 guides the push-pull seat 61 in the horizontal direction through the L-shaped connecting plate 72, so that the push-pull seat 61 keeps moving in the horizontal direction.

[0054] Working principle: when folding blister boxes of different widths is required, the operator rotates two adjacent rotating handles 52 at the same time, the rotating handles 52 rotate the lead screw 51, the lead screw 51 drives the moving seat 53 to move horizontally, and the moving seat 53 causes the U-shaped fixing plate 41 and the folding bottom plate 42 to move horizontally synchronously through the cylinder 43, so that the spacing between the two folding bottom plates 42 matches the width of the blister box to be folded, thereby conveniently realizing the spacing adjustment between the two folding bottom plates 42, and then facilitating the folding operation of blister boxes of different widths;

[0055] By setting two folding bottom plates 42, two cylinders 43, steel bars 46, L-shaped sliding plates 47 and receiving plates 49, when the conveying mechanism 2 conveys the blister box, the blister box passes through the steel bars 46 through the receiving plates 49 and enters between the two folding bottom plates 42 along the L-shaped sliding plates 47. The two folding bottom plates 42 realize two folding positions of the blister, and the steel bars 46 realize the third folding position of the blister box, thereby conveniently realizing the three-side folding of the blister box without a bottom plate. Compared with the existing technology, by installing bottom plates of different sizes, the operating cost of folding the blister box is effectively reduced, and at the same time, personal injuries caused by frequent replacement of bottom plates are avoided;

[0056] When the hemming bottom plate 42 needs to be installed, the operator first places the hemming bottom plate 42 on one side of the U-shaped fixing plate 41, and then manually turns the knob 68, which turns the threaded rod 67, and the threaded rod 67 drives the push-pull seat 61 to move horizontally toward one side of the hemming bottom plate 42, and the push-pull seat 61, the spring rod 62 and the trapezoidal limit block 63 enter the through hole 64, and the trapezoidal limit block 63 moves horizontally along the inner wall of the through hole 64. When the trapezoidal limit block 63 and the trapezoidal limit groove 65 are in contact with each other, the push-pull seat 61, the spring rod 62 and the trapezoidal limit block 63 are in contact with each other, and ... After horizontal correspondence, the spring rod 62 extends and pushes the trapezoidal limit block 63 into the trapezoidal limit groove 65. At this time, the trapezoidal limit block 63 is in a fit state with the trapezoidal limit groove 65. The trapezoidal limit block 63 fixes the folding bottom plate 42 to one side of the U-shaped fixing plate 41 through the trapezoidal limit groove 65, thereby conveniently realizing the fixed installation of the folding bottom plate 42, thereby effectively improving the convenience of installing the folding bottom plate 42, and at the same time facilitating the subsequent replacement of the folding bottom plate 42 by the operator.
