The implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0021] like Figures 1 to 6 As shown, a bag moving mechanism for compounding an inner bag and an outer bag of a composite bag comprises an equipment base 1, a bag moving mechanism 2 and an opening mechanism arranged on the equipment base 1, the opening mechanism comprises opening brackets 4 arranged in pairs, a first driving mechanism 6 for driving the opening brackets 4 to move horizontally and an opening assembly 5 arranged at the end of the opening bracket 4, a bag moving bracket 101 is arranged above the equipment base 1, the bag moving mechanism 2 comprises a guide rail 201 extending along the length direction of the equipment base 1, a mobile platform 202 movably connected to the guide rail 201, a clamping assembly 3 arranged on the mobile platform 202 and a second driving mechanism 203 for driving the mobile platform 202 to reciprocate along the guide rail 201.

[0022] like Figure 1 As shown, when the utility model is in use, one end of the device base 1 is provided with the opening mechanism, and the opening mechanism is used to open the two ends of the outer bag. The upper part of the device base 1 is provided with the bag moving mechanism 2, and the bag moving mechanism 2 is used to pull the inner bag into the outer bag in the open state;

[0023] like Figures 2 to 5As shown in the figure, in the opening mechanism of the present utility model, the opening mechanism includes a pair of opening brackets 4, a first driving mechanism 6 for driving the opening brackets 4 to move towards and away from each other, and an opening assembly 5 provided at the ends of the opening brackets 4. Among them, the opening brackets 4 move towards each other under the drive of the first driving mechanism 6. When the opening brackets 4 move towards each other, the spreading rods 502 on the opening brackets 4 rotate circumferentially around the opening brackets 4, so that the spreading rods 502 extend into the outer bag along the opening of the outer bag and keep the outer bag opening in a spread state;

[0024] Specifically, the first driving mechanism 6 includes a rotary motor 601, transmission gears 602 and a transmission track 603. The number of the transmission gears 602 is two. The inner end surface of the transmission track 603 meshes with the transmission gears 602. The output end of the rotary motor 601 is vertically upward and connected to any one of the transmission gears 602. The number of the opening brackets 4 is two, which are respectively fixedly connected to the transmission tracks 603 on both sides of the transmission gears 602;

[0025] As Figure 3 , Figure 4 and Figure 5 shown, in use, the rotary motor 601 drives the transmission gears 602 to rotate. The transmission gears 602 mesh with the tooth-shaped surfaces of the transmission tracks 603. The rotation of the transmission gears 602 drives the transmission tracks 603 to rotate. The number of the opening brackets 4 is two, which are respectively arranged on the transmission tracks 603 with different movement directions on both sides of the transmission gears 602. The rotation of the transmission gears 602 drives the opening brackets 4 to move towards or away from each other. When the opening brackets 4 move towards each other, the spreading rods 502 extend into the outer bag along the opening of the outer bag, so as to evenly spread the opening of the outer bag to both sides;

[0026] It should be noted that a strip-shaped groove 102 penetrating along its thickness direction is provided along the width direction of the equipment base 1. A rack 103 is provided on the inner surface of one side of the strip-shaped groove 102. The opening assembly 5 includes an annular part 501 sleeved on the opening bracket 4 and a spreading rod 502. A toothed ring is provided on the outer surface of the annular part 501. The outer edge of the toothed ring meshes with the tooth-shaped surface of the rack 103. While the first driving mechanism 6 drives the opening brackets 4 to move towards each other, the annular part 501 rotates self under the meshing transmission of the rack 103 and the toothed ring, so that the spreading rod 502 rotates towards the direction of the outer bag opening. The spreading rod 502 rotates into the outer bag opening in the open state, and keeps the opening of the outer bag in a spread state, so that the openings at both ends of the outer bag maintain the same opening posture;

[0027] It should be noted that the first driving mechanism 6 is arranged below the strip groove 102, the bottom end of the opening bracket 4 is fixedly connected to the first driving mechanism 6, the top end of the opening bracket 4 is bent toward the strip groove 102 and extends upward along the strip groove 102, the length dimension of the rack 103 matches the width dimension of the outer bag in the opening state, when the opening bracket 4 moves toward each other, the annular portion 501 moves toward the middle along the two ends of the rack 103, that is, moves from both sides of the outer bag opening toward the middle, the distance between the end of the rack 103 and the edge of the outer bag opening is equal to the circumferential rotation distance of the opening rod 502, so that the opening rod 502 can rotate into place while moving toward the edge of the outer bag opening to play a better opening role.

[0028] It should be noted that the annular portion 501 is provided with a pair of expansion rods 502 distributed up and down, the expansion rods 502 on both sides are arranged horizontally, and one end is fixed to the outer surface of the annular portion 501, and the annular portion 501 and the expansion rods 502 are both circular cylinders.

[0029] Furthermore, in the above scheme, a suction cup assembly 7 is provided on one side of the device base 1 corresponding to the strip groove 102, and the suction cup assembly 7 includes a suction cup bracket 701, a fourth driving mechanism 703 arranged at the end of the suction cup bracket 701, and a negative pressure suction cup 702 arranged at the output end of the fourth driving mechanism 703. When the outer bag is in an unopened state, the outer bag is spread flat on the device base 1, and the negative pressure suction cup 702 is driven by the fourth driving mechanism 703 to suck up the upper edge of the outer bag, so that the opening of the outer bag is in a half-open state, which facilitates the extension of the opening rod 502 into the outer bag.

[0030] Further, when the opening of the outer bag is opened by the opening mechanism, the inner bag is moved to the outer bag in the open state by the bag moving mechanism 2. Specifically, the guide rail 201 is arranged above the equipment base 1, and the movable platform 202 is sleeved on the guide rail 201. The second driving mechanism 203 is arranged at one end of the guide rail 201, and the output end is connected to the movable platform 202. The second driving mechanism 203 is a linear driving cylinder. Specifically, the bottom end surface of the movable platform 202 is provided with the clamping assembly 3. The second driving mechanism 203 drives the movable platform 202 to reciprocate along the length direction of the guide rail 201, so that the clamping assembly 3 reciprocates in and out along the middle of the outer bag in the open state to move the inner bag into the outer bag.

[0031] like Figure 6As shown in the figure, further, in the above solution, the clamping assembly 3 includes a first L-shaped clamping plate 301 and a second L-shaped clamping plate 302. The first L-shaped clamping plate 301 is fixed to the bottom end face of the moving platform 202, and the second L-shaped clamping plate 302 is movably connected to the moving platform 202. A third driving mechanism 303 for driving the second L-shaped clamping plate 302 to lift is provided at the top of the moving platform 202;

[0032] Further, in the above solution, the second L-shaped clamping plate 302 includes a vertical rod body 304 and a horizontally arranged clamping plate 305. A through hole is provided along the thickness direction of the moving platform 202, and the output end of the third driving mechanism 303 vertically penetrates through the through hole and is connected to the rod body 304;

[0033] It should be noted that in one of the implementation manners, when the inner bag needs to be clamped, the moving platform 202 moves towards the outer bag through the second driving mechanism 203. The first L-shaped clamping plate 301 and the second L-shaped substrate extend into the outer bag from the opening of the outer bag and extend out from the other end following the movement of the moving platform 202. The second L-shaped clamping plate 302 is controlled by the third driving mechanism 303 to move and fit the first L-shaped clamping plate 301 to clamp the inner bag. After the moving platform 202 is reset, the inner bag can be more accurately sent into the opened outer bag.

[0034] The above are only the preferred implementation manners of the present invention. It should be pointed out that for those of ordinary skill in the art of the present technology, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
