Detailed Description

As shown in fig. 1 and 2, the novel carousel-type food bag transfer device comprises a carousel 2 and a main shaft 1, wherein the main shaft 1 is driven to rotate by a main power source, and the carousel 2 realizes intermittent rotation. Four bag clamping mechanisms 3 are equidistantly installed on the turntable 2, each bag clamping mechanism 3 comprises a static clamp 30 and a movable clamp 31, one end of each movable clamp 31 is rotatably arranged through a rotating shaft 32, and the movable clamp 31 rotates to be closed with the static clamp 30 to clamp the packaging bag.

As shown in fig. 1, the four bag clamping mechanisms 3 respectively correspond to the bag loading station a, the transition station C and the two bag discharging stations B which are opposite to each other, the packaging bag 5 is always loaded at the bag loading station a, the packaging bag 5 is discharged from the bag discharging station B all the time, when the packaging bag 5 is discharged from the bag discharging station B, the packaging bag is clamped by a mechanical arm and sent to the vacuum box 6 for vacuumizing, because the two sides of the interior of the vacuum box 6 can only be vacuumized at the same time (the vacuumization is carried out after the covers at the two sides are closed), the upper bag outlet station B and the lower bag outlet station B in the figure 1 have to synchronously discharge bags, and only in these two positions, the bag can be discharged, on the basis of which, in the four bag holder mechanisms 3, the opening and rotating directions of the movable clamps 31 of two adjacent bag clamping mechanisms 3 are clockwise, and the opening and rotating directions of the movable clamps 31 of the other two adjacent bag clamping mechanisms 3 are counterclockwise.

As shown in fig. 5, when the clamping openings of the two bag clamping mechanisms 3 at the upper and lower bag outlet stations B face to the left, the vacuum box 6 is on the left, and the movable clamps 31 of the two bag clamping mechanisms 3 are half opened, the mechanical arm takes away the upper and lower packaging bags together; and when two bag clamp mechanism 3 that are in a bag station B press from both sides the mouth and all face right, the bag clamp mechanism 3 that is located above bag station B is closed at this moment to prevent that the wrapping bag from dropping, and the bag clamp mechanism 3 that is located below bag station B is half-open, because this bag clamp mechanism 3 that goes out bag station B will half-open all the time, also fully open when going to last bag station A is prepared for simultaneously.

Here, the term "fully opened" refers to an angle at which the movable clamp 31 is opened to allow the packaging bag 5 to enter, and is generally 90 °, and the term "half opened" refers to an angle at which the movable clamp 31 is opened to allow the packaging bag 5 to be taken out of the bag, and is generally less than 45 °.

In order to make the clamp 31 realize the above-mentioned action, the utility model discloses a cam mechanism 4 of original drives, under cam mechanism 4's drive, through the transmission of transmission subassembly again, moves the clamp 31 and realizes opening the clamp (move promptly the clamp 31 and move the transmission subassembly transmission that the clamp 31 opened the clamp and be connected), and moves the clamp 31 and realize closing the clamp under the effect of piece 38 that resets (move promptly the clamp 31 and order about to move the reset piece 38 that the clamp 31 closed the clamp and be connected). Therefore, a cam mechanism 4 for driving the transmission assembly to move is arranged below the turntable 2, the cam mechanism 4 includes a first cam 40, a second cam 41 and a clamping opening power source (a motor, not shown) for driving the first cam 40 and the second cam 41 to rotate back and forth, and the first cam 40 and the second cam 41 can rotate back and forth together within an angle by the driving of the clamping opening power source, so as to control the clamping opening and the clamping closing of the clamp 31.

Of course, the transmission assembly includes an acting element 37 acting on the cam mechanism 4 (the acting element 37 may be a roller, a slider or other acting element capable of acting on a cam, where the roller friction is the smallest, and the effect is better), and the cam mechanism 4 directly acts on the acting element 37 to drive the transmission assembly to drive the movable clamp 31 to open. In order to control the movable clamps of the four bag clamp mechanisms 3 through the cam mechanism 4 to realize the above-mentioned actions, as shown in fig. 4, the utility model discloses a first cam 40 has a first high-position bulge 401 which lets the movable clamp 31 be fully opened through the acting piece 37 at the position corresponding to the bag feeding station a, and a first cam 40 has two first low-position bulges 402 which lets the movable clamp 31 be half opened through the acting piece 37 at the position corresponding to the two bag discharging stations B; the second cam 41 has a second high-level projection 411 for fully opening the movable clamp 31 through the acting element 37 at a position corresponding to the bag feeding station a, and the second cam 41 has a second low-level projection 412 for half opening the movable clamp 31 through the acting element 37 at a position corresponding to the bag discharging station B; wherein the acting pieces 37 of the two bag clamping mechanisms 3 with the same opening and clamping rotation directions of the movable clamp 31 act on the first cam 40, and the acting pieces 37 of the other two bag clamping mechanisms 3 act on the second cam 41.
