The mechanisms located at the periphery of the turntable 1 are substantially the same as those of the prior art, such as a bag feeding device, a feeding device and a vacuum bag sealing device, and are not described in detail herein. The main improvements of the utility model are a bag clamp mechanism 2 and a bag supporting mechanism 4, which are specifically described below.

As shown in fig. 1, each bag clamp mechanism 2 includes two left and right bag clamp assemblies 20, and as shown in fig. 2, each bag clamp assembly 20 includes a sleeve 201, a pull rod 202, and two clamp blocks 200. The sleeve 201 is rotatably connected to the turntable 1 (the sleeve 201 rotates to expand the bag mouth), the pull rod 202 is slidably arranged in the sleeve 201, one of the clamping blocks 200 is rotatably connected to the front end of the sleeve 201 up and down through a hinge arm 203, the pull rod 202 is hinged to the hinge arm 203, the pull rod 202 is connected with an upper guide wheel 204, as shown in fig. 5, a guide member 3 is slidably arranged on the turntable 1 through a guide rail (the guide member 3 is slidably arranged on the guide rail which is arranged on the turntable), the guide member 3 is provided with a swing groove 30, and the upper guide wheel 204 is positioned in the swing groove 30 (the sleeve 201 rotates, and the upper guide wheel 204 moves in the swing groove 30); in addition, the turntable 1 is provided with a bag supporting mechanism 4, the bag supporting mechanism 4 comprises a lower supporting plate 40 which can move up and down, and a bag supporting mechanism 4 is correspondingly arranged below each bag clamping mechanism 2.

The working principle of the turntable type mechanical clamping device is as follows: when the bag clamping mechanism 2 clamps the bag at the bag loading station, that is, the two clamping blocks 200 of each bag clamping assembly 20 clamp the bag, and the bag is turned to the bag opening station, the guide member 3 is driven to move forward, the guide member 3 pulls the upper guide wheel 204 to move synchronously, and since the upper guide wheel 204 is connected to the pull rod 202, the pull rod 202 is also pulled to move forward, and the clamping blocks 200 of the bag clamping mechanism 2 are turned downward by 90 ° (as shown in fig. 2); then, the bag is horizontally laid by means of external positive pressure blowing (in the working position, a blowing device is arranged on the outer side of the rotating disc 1), and then the lower supporting plate 40 of the bag supporting mechanism 4 moves upwards to support the bag (shown in fig. 7); then the bag clamp mechanism 2 comes to the feeding station, at which time the sleeve 201 of each bag clamp assembly 20 is driven to rotate, as shown in fig. 8, the front ends of the two sleeves 201 of the bag clamp mechanism 2 are close, because the guide member 3 is provided with the swing groove 30, the upper guide wheel 204 can move in the swing groove 30, so that the clamp blocks 200 of the two bag clamp assemblies 20 are close without influencing the relationship with the guide member 3, the mouth of the bag is opened, and the feeding device feeds the material into the packaging bag; after the materials are added, the bag clamping mechanism 2 tightens the bag opening of the packaging bag, and finally the packaging bag is sent into a vacuum bag sealing device for vacuumizing and heat sealing.

The slip of guide 3 on carousel 1 can be realized through independent power supply drive, also can utilize the rotation of carousel 1 self to realize removing, but the former need install independent power supply, because carousel 1 is pivoted, consequently more difficult realization, also can realize certainly, only the structure is more complicated, and the cost is than higher, for this reason the utility model discloses specifically adopt the latter, utilize the rotation of carousel 1 self promptly, order about the slip of guide 3 on carousel 1. The concrete structure is as follows: a cam groove 13 is provided in the base, and a guide wheel 31 is connected to the guide 3, the guide wheel 31 being positioned in the cam groove 13. With the rotation of the rotary disc 1, the guide wheel 31 on the guide member 3 moves in the cam groove 13, and the cam groove 13 can be designed to guide the movement of the guide wheel 31, so that the guide member 3 can be driven to move back and forth on the rotary disc 1. The structure greatly reduces the equipment cost and is not easy to break down.

As described above, after the bag is laid down, the bag needs to be held by the lower supporting plate 40 of the bag holding mechanism 4, and therefore, the lower supporting plate 40 of the bag holding mechanism 4 needs to move up and down, when the lower supporting plate 40 is at a low position, there is enough space between the lower supporting plate 40 and the bag clamping mechanism 2 to allow the bag to be put in, and when the lower supporting plate 40 is at a high position, the bag is held by the lower supporting plate 40. The lower support plate 40 moves up and down in many ways, and the following description specifically describes the bag supporting mechanism 4: as shown in fig. 3, a support 49 is connected to the turntable 1, a guide rod 46 is arranged on the support 49, an upper connecting member 41 is connected to the guide rod 46, the upper connecting member 41 is hinged to an upper connecting arm 42 and a lower connecting arm 43, the bottom of the lower supporting plate 40 is connected to a connecting column 401, the upper connecting arm 42 and the lower connecting arm 43 are correspondingly hinged to the connecting column 401 up and down, a lower connecting member 45 capable of sliding up and down is arranged on the guide rod 46, the lower connecting member 45 is hinged to one end of the driving arm 44, and the other end of the driving arm 44 is hinged to the lower connecting arm 43. With this structure, as long as the lower connecting member 45 is driven to move up and down, the lower connecting member 45 can drive the lower supporting plate 40 to move up and down through the driving arm 44. The lower supporting plate 40 of the bag supporting mechanism 4 does not move up and down in a horizontal posture, but moves up and down (can also be called as swinging, but the central point of the lower supporting plate 40 moves up and down) in a movement posture that the movement amplitude of the front end of the lower supporting plate 40 is larger than that of the rear end, and the structure has the advantage that a sufficient bag feeding space can be formed between the front end of the lower supporting plate 40 and the bag clamping mechanism 2 only by a transmission structure with a small transmission stroke, so that the transmission structure is protected, the noise of equipment is reduced, and meanwhile, the optimization of the transmission structure is more facilitated.

Similarly, the slip of lower connecting piece 45 on guide arm 46 can be realized through independent power supply drive, also can utilize the rotation of carousel 1 self to realize removing, but the former need install independent power supply, because carousel 1 is the pivoted, consequently more difficult realization, also can realize certainly, only the structure is more complicated, and the cost is than higher, for this reason the utility model discloses specifically adopt the latter, utilize the rotation of carousel 1 self promptly, order about down connecting piece 45 and remove on guide arm 46. The concrete structure is as follows: as shown in fig. 5, the lower connecting member 45 is connected with a positioning roller 47, as shown in fig. 9, the base is provided with a lifting cam plate 11, the positioning roller 47 acts on a cam surface of the lifting cam plate 11, the cam surface has a low cam surface 110 and a high cam surface 111, the base is provided with a connecting wheel block 5 for connecting the positioning roller 47, the connecting wheel block 5 is positioned on one side of the lifting cam plate 11, the height of the connecting wheel block 5 is the same as that of the high cam surface 111 (the height of the connecting wheel block 5 can be higher), and the connecting wheel block 5 is in transmission connection with a connecting wheel power source for driving the connecting wheel block 5 to partially move from the side of the high cam surface 111 to the side of the low cam surface 110; and a lifting power source 6 for lifting the lower connecting piece 45 is arranged on the machine base.

The lifting principle of the lower connecting member 45 is as follows: when the bag supporting mechanism 4 and the bag clamping mechanism 2 come to a specific station, the lifting power source 6 drives the lower connecting piece 45 to be lifted, so that the positioning roller 47 on the lower connecting piece 45 rises to a certain height from the low cam surface 110 of the lifting cam disc 11, as shown in fig. 9 and 10, then the connecting wheel power source drives the connecting wheel block 5 to partially move from the side of the high cam surface 110 to the side of the low cam surface 110, then the lifting power source 6 lifts the lower connecting piece 45, so that the positioning roller 47 on the lower connecting piece 45 acts on the high cam surface 110 of the lifting cam disc 11, the lower supporting plate 40 is at a high position to support a bag, and as the turntable 1 rotates, the positioning roller 47 on the lower connecting piece 45 runs on the high cam surface 110 of the lifting cam disc 11, and the lower supporting plate 40 always supports the bag to run through a plurality of stations. It is worth mentioning that, since the lower plate 40 needs to be lifted from the lower position to the upper position at one station, the lifting range is large within a certain rotation angle range, and therefore, it is difficult to drive the lower plate 40 to be lifted by lifting the cam surface of the cam plate 11, and the lifting is preferably realized by the above structure.

Of course, in order to prevent the lifting power source 6 or the connecting wheel power source from failing to cause the lower positioning roller 47 to be unable to transit from the low cam surface to the high cam surface of the lifting cam plate 11, as shown in fig. 10, the present invention also transits between the low cam surface 110 and the high cam surface 111 of the cam surface through the inclined surface 112, and the inclined surface 112 can ensure that the positioning roller 47 transits from the low cam surface 110 to the high cam surface 111 of the lifting cam plate 11 in case of the above failure, so as to prevent the positioning roller from being stuck and dead. As described above, just because the moving posture of the lower tray 40 with the moving amplitude of the front end larger than that of the rear end moves up and down, the transmission stroke of the transmission structure is reduced, so that the height difference between the low cam surface 110 and the high cam surface 111 of the cam surface is reduced as much as possible, and the transition of the inclined surface 112 between the low cam surface 110 and the high cam surface 111 of the cam surface can be realized (if the height difference is too large, the transition of the inclined surface cannot be realized, and the positioning roller 47 cannot climb onto the high cam surface 111 from the low cam surface 110 of the cam surface), which is the reason of "optimization of the more useful transmission structure" described above.

Some of the packaged materials contain juice, and in order to prevent the juice from flowing out by centrifugal force, it is preferable to incline the bottom of the bag downward so that the juice in the bag lying flat does not flow out, and in this case, the lower plate 40 is lowered a little, and for this reason, the present invention further includes a guide rod 46 slidably provided on a support 49 up and down, and a lowering roller 48 connected to a lower end of the guide rod 46, and a lowering cam plate 12 provided on the support, the lowering cam plate 12 having a lowering cam surface or a lowering cam groove for moving the lowering roller 48 downward. With this structure, the guide rod 46 can be lifted and lowered as the lowering roller 48 moves on the lowering cam plate 12, and the lifting and lowering of the guide rod 46 can directly drive the lower support plate 40 to move up and down, so that the bottom of the bag can be inclined downward to prevent juice from flowing out due to centrifugal force. Of course, some packaged materials do not contain juice and do not require such a construction.

As described above, the two clamp blocks 200 of the bag clamp assembly 20 clamp the bag, so that the two clamp blocks 200 are hinged together and clamped together by the tension spring, as shown in fig. 2, one of the clamp blocks 200 is hinged to the sleeve 201 by the hinge arm 203, the other clamp block 200 is connected with the unclamping roller 205, and one side of the turntable 1 is provided with an unclamping mechanism acting on the unclamping roller 205 to drive the two clamp blocks 200 to open. When it is desired to open the two clamp blocks 200, the opening mechanism acts on the opening guide wheel 205, such that one of the clamp blocks 200 is actuated, the two clamp blocks 200 are opened, the bag is placed between the two clamp blocks 200, and then the opening mechanism no longer acts on the opening guide wheel 205, and the two clamp blocks 200 are clamped together under the action of the tension spring, thereby clamping the bag.

Finally, it is worth mentioning that, in order to order about sleeve 201 to rotate, as shown in fig. 4, the utility model discloses be connected with gear 206 on sleeve 201, gear 206 meshing on two sleeves 201 of bag clamp mechanism 2 is in the same place, is connected with on the sleeve 201 and opens the bag guide pulley, and is equipped with on the frame and opens the bag cam, opens the bag guide pulley and locates on opening the bag cam. One of the sleeves 201 can be driven to rotate by guiding the bag opening cam to the bag opening guide wheel, and the two sleeves 201 of the bag clamping mechanism 2 can rotate relatively by the transmission of the gear 206, so that the opening of the bag opening is realized. Of course, other structures may be adopted to realize the rotation of the sleeve 201, for example, the invention patent with the publication number CN103241410B discloses a manner of rotating the sleeve, and will not be described herein again.
