DETAILED DESCRIPTION

[0030] 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 of 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. Specific embodiment one:

[0032] See also Figure 1-8 As shown, the utility model is a medicine bag clamping mechanism, comprising a mounting base 1 and two extension clamps 2. The mounting base 1 comprises a rectangular plate body 11. At least two single ears 12 for mounting and fixing are fixed to one side of the rectangular plate body 11. A guide rail 13 is fixed to the other side of the rectangular plate body 11. The two extension clamps 2 are slidably mounted on the guide rail 13 through a slider 3 respectively, and the two extension clamps 2 are arranged opposite to each other. The two extension clamps 2 are driven to move relative to each other by a driving assembly 4 fixed to the side of the rectangular plate body 11. The mounting base 1 is installed on a turntable or a reciprocating linear row to participate in the medicine packaging line.

[0033] The extension clamp 2 includes a tube body 21, a telescopic rod 22, a clamping plate 23, a connecting rod 24 and a driving plate 25. The telescopic rod 22 is installed inside the tube body 21. The driving plate 25 is fixed to the telescopic end of the telescopic rod 22 by bolts. A rectangular flange plate 211 connected and matched with the slider 3 is fixed to the bottom of the tube body 21. A rack 212 matched with the driving assembly 4 is fixed to the side of the rectangular flange plate 211. A rectangular groove 213 for guiding and matching with the driving plate 25 is opened on the side wall of the other end of the tube body 21. A clamping bottom plate 214 is fixed to the outer wall of the rectangular groove 213 at the end of the tube body 21. The clamping plate 23 includes a circular sleeve 231. The circular sleeve 231 is installed between the opposite inner walls of the rectangular groove 213 through a first rotating shaft. A clamping pressure plate 232 matched with the clamping bottom plate 214 is fixed to the outer wall of the circular sleeve 231. The outer wall of the circular sleeve 231 is also fixed with double ears 233, and the double ears 233 are arranged perpendicularly to the clamping plate 232. The double ears 233 are connected to one end of the connecting rod 24 through a second rotating shaft. A U-shaped notch 251 is opened at the free end of the driving plate 25. The other end of the connecting rod 24 is installed between the inner walls opposite to the U-shaped notch 251 through a third rotating shaft.

[0034] When the telescopic rod 22 retracts, the clamping plate 23 moves closer to the clamping bottom plate 214 to clamp the medicine bag. When the telescopic rod 22 extends, the clamping plate 23 opens outward to achieve the clamping and releasing actions of the medicine bag.

[0035] In order to make the clamping bottom plate 214 and the clamping pressure plate 232 clamp the medicine bag therebetween more stably, a toothed groove 215 is provided on the clamping bottom plate 214. A rubber pad 234 is fixed on the side of the clamping pressure plate 232 relative to the clamping bottom plate 214. A soft rubber pad 234 is used on one side and a toothed groove 215 is provided on the other side. When clamping, the unit area pressure of the medicine bag on the toothed groove 215 side and the medicine bag increases, and the friction coefficient of the medicine bag on the rubber pad 234 side increases, and the overall friction force is effectively increased.

[0036] The telescopic rod 22 can be an electric telescopic rod or a cylinder. Preferably, the cylinder has a fast response speed.

[0037] The driving assembly 4 includes a gate-shaped seat plate 41 fixed on the rectangular plate body 11. A motor 42 is installed on the inner side of the gate-shaped seat plate 41. A driving gear 43 is installed after the output shaft of the motor 42 passes through the gate-shaped seat plate 41. A pair of baffles 44 for limiting and guiding the two racks 212 are fixed on the inner wall of the gate-shaped seat plate 41. A transmission shaft is installed on the top wall of the gate-shaped seat plate 41 through a bearing. A driving output gear 45 that cooperates with the two racks 212 is fixed to one end of the transmission shaft located on the inner side of the gate-shaped seat plate 41. A transmission gear 46 that meshes with the driving gear 43 is fixed to the other end of the transmission shaft. The extension clamp 2 uses the rack 212 to control the relative distance, which can conveniently control the clamping width in the initial state and has a wide range of adaptability to the width of the medicine bag.

[0038] The motor 42 of the driving assembly 4 drives the two racks 212 through the gear group consisting of the driving gear 43, the transmission gear 46 and the driving output gear 45 to drive the two extension clamps 2 to move relative to each other, thereby expanding the bag mouth clamped in the medicine bag state, facilitating the filling and packaging of liquid or powder medicine.
