[0023] The present invention provides a packaging device for medicines, such as Figure 1 As shown, including:

[0024] A frame, on which a winding roller 411, a tensioning device, a bag-supporting mechanism 42 and a web cutting mechanism 43 are arranged;

[0025] The winding roller 411 is used to wind the ziplock bag roll, and the tightening device is used to tighten the ziplock bag roll extending from the winding roller 411;

[0026] The bag-opening mechanism 42 is capable of opening the bag opening of the ziplock bag roll extending from the tightening device;

[0027] The web cutting mechanism 43 can cut the ziplock bag web extending from the bag-opening mechanism 42 .

[0028] Here, if Figure 1 As shown, the tensioning device includes six tensioning rollers 412, and the six tensioning rollers 412 are all located above the winding roller 411, wherein the six tensioning rollers 412 are divided into two groups, wherein the first group includes four tensioning rollers 412, and the second group includes two tensioning rollers 412, the first group is located above the second group, and a slide rail 413 extending in the up and down direction is provided on the frame, and one of the tensioning rollers 412 in the second group can slide in the up and down direction along the slide rail 413, and the tensioning roller 412 can move downward along the slide rail 413 under the action of its own gravity, so that the ziplock bag roll can be tightened.

[0029] The four tensioning rollers 412 in the first group are arranged in a row in the left-right direction, and a roller is provided corresponding to the leftmost and rightmost tensioning rollers 412. The outer side surface of the roller abuts against the outer side surface of the tensioning roller 412, thereby preventing the tensioning roller 412 from rotating too fast. In addition, the roller can move in the left-right direction, thereby adjusting the degree of extrusion between the roller and the corresponding tensioning roller 412.

[0030] In this embodiment, the bag-supporting mechanism 42 includes: a horizontal rod 4211 and a vertical rod 4212, wherein the horizontal rod 4211 extends in the front-to-back direction, and the top end of the vertical rod 4212 is fixedly connected to the front end of the horizontal rod 4211;

[0031] A first vertical plate 4221 and a second vertical plate 4222 are disposed below the horizontal rod 4211. The first and second vertical plates are symmetrically and parallelly disposed in the left direction. The first and second vertical plates can be away from or close to each other.

[0032] Two rotating wheels 423 distributed along the left-right direction are arranged below the first and second vertical plates. The rotating shafts 4232 of the two rotating wheels 423 extend along the front-back direction, and the outer side surfaces of the two rotating wheels 423 abut against each other.

[0033] Here, if Figure 2 and Figure 3 As shown, the first vertical plate 4221 is located on the right side, and the second vertical plate 4222 is located on the left side; a first cylinder 4281 is arranged on the right side of the first vertical plate 4221, and the first cylinder 4281 can drive the first vertical plate 4221 to move in the left and right directions; a second cylinder 4282 is arranged on the left side of the second vertical plate 4222, and the second cylinder 4282 can drive the second vertical plate 4222 to move in the left and right directions; therefore, under the drive of the first and second cylinders, the first and second vertical plates can move away from or close to each other.
