Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] To achieve the above objectives, the technical solution of this utility model is as follows:

[0024] See Figure 1-3As shown, this embodiment provides a packaging bag conveying device, including: a bag storage bin 21, a bag retrieval pull-down module 22, and a bag opening and transfer assembly 23. The bag storage bin 21 includes a packaging bag placement seat 211, and a packaging bag placement position 212 is provided on the packaging bag placement seat 211. An opening 213 is provided at the bottom of the packaging bag placement position 212. The bag retrieval pull-down module 22 is located below the opening 213. The bag opening and transfer assembly 23 is provided on the side of the bag storage bin.

[0025] Furthermore, several protective baffles 214 are provided around the perimeter of the opening 213, and a support piece 215 for supporting the guarantee bag is provided at the bottom of the protective baffle 214. The protective baffles 214 can limit the guarantee bag on the packaging bag placement position 212 and are supported by the support piece 215.

[0026] Furthermore, the bag-retrieving pull-down module 22 includes a bag-retrieving pull-down motor 221, a bag-retrieving pull-down swing rod 222, and a bag-retrieving pull-down suction cup 223. One end of the bag-retrieving pull-down swing rod 222 is connected to the output end of the bag-retrieving pull-down motor 221, and the other end is connected to the bag-retrieving pull-down suction cup 223. In this application, when the bag-retrieving pull-down motor 221 is working, it can drive the bag-retrieving pull-down swing rod 222 to swing up and down around the motor output shaft, thereby driving the bag-retrieving pull-down suction cup 223 to move up and down. The bag-retrieving process of the bag-retrieving pull-down module 22 is as follows: the bag-retrieving pull-down suction cup 223 moves upward to below the packaging bag placement position 212 and sucks up the packaging bag on the packaging bag placement position 212 from the opening 213; then it moves downward to pull the packaging bag on the packaging bag placement position 212 from the opening 213, and continues to move downward until the packaging bag is adjusted to a horizontal state for the bag opening and transfer component 23 to remove.

[0027] Furthermore, two horizontal support plates 24 are provided below the packaging bag placement position 212, and the upper ends of the horizontal support plates 24 are fixedly connected to the packaging bag placement seat 211; the bag-removing pull-down suction cup 223 is disposed between the two horizontal support plates 24, and a space is also provided between the two horizontal support plates 24 to avoid the vertical movement of the bag-removing pull-down suction cup 223. In this application, after the bag-removing pull-down suction cup 223 picks up the packaging bag, it adjusts the packaging bag to a horizontal state and places it on the two horizontal support plates 24 for the bag opening and transfer component 23 to remove.

[0028] Furthermore, a tray 25 is provided below the horizontal support plate 24. Under normal circumstances, the bag-removing suction cup 223 picks up only one packaging bag at a time. When the suction cup pulls out more than one packaging bag, the excess packaging bags will fall onto the tray 25 below, thereby avoiding affecting the operation of the device.

[0029] Furthermore, the bag opening and transfer assembly 23 includes a horizontal transfer module 231 and a bag opening module 232. The bag opening module 232 is connected to the horizontal transfer module 231, and the bag opening module 232 and the horizontal support plate 24 are on the same horizontal plane. The horizontal transfer module 231 can drive the bag opening module 232 to move back and forth between the horizontal support plate 24 and the product bagging mechanism, which can suck open the packaging bag on the horizontal support plate 24 and transfer it to the product bagging mechanism for product bagging.

[0030] Furthermore, the horizontal transfer module 231 includes a horizontal transfer motor 2311, a horizontal transfer drive wheel 2312, a horizontal transfer timing belt 2313, a horizontal transfer driven wheel 2314, and a timing belt pressure plate 2315. The horizontal transfer drive wheel 2312 is connected to the output end of the horizontal transfer motor 2311. The horizontal transfer drive wheel 2312 and the horizontal transfer driven wheel 2314 are connected by the horizontal transfer timing belt 2313. The bag opening module 232 is fixedly installed on the horizontal transfer timing belt 2313 by the timing belt pressure plate 2315. When the horizontal transfer module 231 is working, the horizontal transfer motor 2311 drives the horizontal transfer timing belt 2313 to rotate, thereby realizing the horizontal movement of the bag opening module 232.

[0031] Furthermore, the horizontal transfer module 231 also includes a horizontal transfer guide rail 2316 parallel to the horizontal transfer timing belt 2313. A horizontal transfer slider 2317 is slidably mounted on the horizontal transfer guide rail 2316, and the bag opening module 232 is fixedly connected to the horizontal transfer slider 2317. During the horizontal movement of the bag opening module 232, it is guided by the horizontal transfer guide rail 2316 to prevent positional deviation.

[0032] Furthermore, the bag opening module 232 includes a bag opening mounting plate 2321, a bag opening drive motor 2322, two bag opening suction cups 2323 arranged vertically opposite each other, and two sets of suction cup transmission assemblies 2324 arranged vertically symmetrically. The bag opening drive motor 2322 is fixedly mounted on the bag opening mounting plate 2321. The two bag opening suction cups 2323 are respectively connected to the bag opening drive motor 2322 through a set of suction cup transmission assemblies 2324, so that the two bag opening suction cups 2323 can move synchronously towards each other or backwards to realize the suction opening of the packaging bag. When the bag opening module 232 is working, the two bag opening suction cups 2323 open backwards, respectively located on the upper and lower sides of the packaging bag, and then move towards each other to clamp and suction the packaging bag from the upper and lower sides, and then move backwards to suction and open the packaging bag, and move it to the product bagging mechanism for positioning, so as to facilitate the product bagging.

[0033] Furthermore, the suction cup transmission assembly 2324 includes a first joint 23241, a second joint 23242, a locking block 23243, a connecting shaft 23244, a swing seat 23245, a swing shaft 23246, and a suction cup fixing plate 23247. The output end of the bag opening drive motor 2322 is connected to the swing plate 23248. The first joints 23241 of the two sets of suction cup transmission assemblies 23244 are symmetrically rotatably connected to the two ends of the swing plate 23248, and the end of the first joint 23241 away from the swing plate 23248 is connected to the second joint. One end of the second joint 23242 is fixedly connected, and the other end of the second joint 23242 is rotatably connected to the locking block 23243. The locking block 23243 is fixedly connected to one end of the connecting shaft 23244, and the other end of the connecting shaft 23244 is fixedly connected to the swing seat 23245. The end of the swing seat 23245 away from the connecting shaft 23244 is rotatably connected to one end of the swing shaft 23246. The other end of the swing shaft 23246 is fixedly connected to the suction cup fixing plate 23247, and the bag opening suction cup 2323 is fixed on the suction cup fixing plate 23247. With the above structural design, the bag opening drive motor 2322 can drive the two sets of symmetrical suction cup transmission components 2324 to move synchronously and symmetrically up and down through the up and down swing of the swing plate 23248. This, in turn, can drive the two bag opening suction cups 2323 to move synchronously towards or away from each other in the up and down direction, thus achieving bag opening by adsorption. The first joint 23241, the second joint 23242, the locking block 23243, the connecting shaft 23244, the swing seat 23245, and the swing shaft 23246 are rotatably or fixedly connected to each other. This allows the swing seat 23245 and the swing shaft 23246 to swing up and down with the connecting shaft 23244 as the axis. During the swing, the movement can reduce vibration, thereby driving the bag opening suction cups 2323 to move stably up and down.

[0034] Furthermore, the suction cup transmission assembly 2324 also includes a bearing seat 23249, a joint fixing plate 23250, a third joint 23251, a joint connecting rod 23252, a fourth joint 23253, and a swing shaft connecting plate 23254. The bearing seat 23249 is fixed on the bag opening mounting plate 2321. The connecting shaft 23244 passes through the bearing seat 23249 and is connected to the bearing seat 23249 through a bearing. One end of the joint fixing plate 23250 is fixed on the bearing seat 23249, and the other end is rotatably connected to one end of the third joint 23251. The other end of the third joint 23251 is fixedly connected to one end of the joint connecting rod 23252 and the other end is fixedly connected to one end of the fourth joint 23253. The other end of the fourth joint 23253 is rotatably connected to one end of the swing shaft connecting plate 23254. The other end of the swing shaft connecting plate 23254 is fixedly connected to the end of the swing shaft 23246 near the swing seat 23245. Through the above structural design, the swing seat 23245 and the swing shaft 23246 can be held in place by the movable buffer structure formed by the joint fixing plate 23250, the third joint 23251, the joint connecting rod 23252, the fourth joint 23253, and the swing shaft connecting plate 23254 during the up and down swinging process. This buffer structure can also cushion the swinging of the swing seat 23245 and the swing shaft 23246, reducing their vibration. The swing seat 23245 can not only drive the swing shaft 23246 to swing up and down, but also provide a certain degree of freedom of movement for the swing shaft 23246 through the rotational connection between the two, making the swinging of the swing shaft 23246 more stable, thereby improving the stability of the bag opening suction cup 2323.

[0035] Furthermore, the first joint 23241, the second joint 23242, the third joint 23251, the joint connecting rod 23252, and the fourth joint 23253 all adopt fisheye joint bearings. One end of the fisheye joint bearing can be rotatably connected to other components through a rotating shaft, and the other end is a rod-shaped structure that can be fixed with other components, thereby realizing the transmission and shock absorption effect of the suction cup transmission assembly 2324.

[0036] Furthermore, a bearing is provided at one end of the swing shaft 23246, which is rotatably connected to the swing seat 23245 through the bearing.

[0037] Furthermore, the horizontal transfer slider 2317 is fixed on the bag opening mounting plate 2321, and the synchronous belt pressure plate 2315 is fixed on the bearing seat 23249 of one of the suction cup transmission components 2324.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
