Description

Technical Field

[0001] The utility model belongs to the field of nut filling, in particular to a bag feeding and straightening mechanism for a nut filling machine. Background Art

[0002] Nuts are a type of closed fruit with a hard peel and one or more seeds. Nuts are the essence of plants and are generally rich in nutrients. They contain high levels of protein, oil, minerals, and vitamins. They are very effective in promoting human growth and development, strengthening physical fitness, and preventing diseases. When processing nuts, the last step is to bag the nuts for subsequent storage.

[0003] After the nuts are filled, the filled bags need to be sent to the next station for sealing. In existing factories, when the nuts are filled, most of them use a conveyor to directly send the filled bags to the next station. In this way, the filled bags are prone to tilt during the conveying process, resulting in unstable bag delivery. Although there is also a straightening mechanism above the conveyor to clamp and straighten the filled bags, the nuts are prone to fall from the bag opening. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a bag feeding and straightening mechanism for a nut filling machine, aiming to solve the problem that the bag feeding process of the existing bag feeding and straightening mechanism for nut filling machines is unstable and nuts are easy to fall from the bag mouth.

[0005] The utility model adopts the following technical scheme: the bag feeding and straightening mechanism includes a carrier, a slide seat is provided at the bottom of the carrier, a pair of clamping arms are rotatably provided at the bottom of the slide seat, a pair of clamping rods are provided inwardly on the clamping arms, a clamping plate is commonly provided on the same pair of clamping rods, a pair of connecting plates are formed downwardly on the clamping arms, a clamping frame is provided inwardly on the same pair of connecting plates, a clamping mechanism for driving the two clamping arms to clamp is provided on the slide seat, the clamping mechanism includes a pair of clamping cylinders rotatably mounted on the slide seat, the two clamping cylinders are oppositely arranged, rotating plates are rotatably provided on both sides of the slide seat, the top of the rotating plate is rotatably connected to the driving shaft of the clamping cylinder, and the bottom is rotatably connected to the clamping arm.

[0006] Furthermore, the connecting plate is provided with a plurality of adjustment holes along the height direction, the clamping frame comprises a pair of threaded rods, a clamping plate is provided at the ends of the two threaded rods, a pair of locking nuts are provided on the threaded rods, and the locking nuts are located on both sides of the connecting plate.

[0007] Furthermore, a driving wheel and a driven wheel are respectively provided on the side walls of the carrier, and a matching belt is sleeved between the driving wheel and the driven wheel. The slide seat is connected to the belt through a connecting block, and a sliding motor for driving the driving wheel to rotate is also provided on the carrier.

[0008] Furthermore, the clamping plate is located directly above the clamping frame.

[0009] The beneficial effect of the utility model is that after the nut filling is completed, the transmission platform is supported on the filling bag, and at this time the clamping mechanism drives the two clamping arms to rotate toward each other until the clamping frame clamps and straightens the packaging bag, and at this time the bag mouth of the filling bag is clamped by the two clamping plates, and then the bag opening mechanism is reset, the bag clamping mechanism releases the filling bag, and finally the slide seat slides backward, and the transmission platform starts to work at the same time until the filling bag is sent to the next station for sealing the bag mouth of the canning bag.

[0012] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0013] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0014] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0015] Combination Figure 1-2 As shown, the bag feeding and straightening mechanism includes a carrier 1, a slide seat 2 is provided at the bottom of the carrier 1, a pair of clamping arms 3 are rotatably provided at the bottom of the slide seat 2, a pair of clamping rods 4 are provided inwardly on the clamping arms 3, and a clamping plate 5 is provided on the same pair of clamping rods 4, a pair of connecting plates 6 are formed downwardly on the clamping arms 3, and a clamping frame 7 is provided inwardly on the same pair of connecting plates 6, and a clamping mechanism for driving the two clamping arms 3 to clamp is provided on the slide seat 2, and the clamping mechanism includes a pair of clamping cylinders 8 rotatably mounted on the slide seat 2, and the two clamping cylinders 8 are oppositely arranged, and rotating plates 9 are rotatably provided on both sides of the slide seat 2, respectively, the top of the rotating plate 9 is rotatably connected to the driving shaft of the clamping cylinder 8, and the bottom is rotatably connected to the clamping arm 3, and the clamping plate 5 is located directly above the clamping frame.

[0016] The bag-feeding and righting mechanism is mainly used in conjunction with a filling machine. In the embodiment, a pair of bag-clamping mechanisms are provided at both ends of the filling bucket of the filling machine. A transmission platform is provided directly below the bag-feeding and righting mechanism. The filling machine is also provided with a bag-opening mechanism.

[0017] After the nuts have been processed, they need to be filled with a filling machine to facilitate their subsequent storage. When the nuts are being filled, the two ends of the bag opening of the filling bag used to fill the nuts are clamped by the bag clamping mechanism, and the bag opening of the filling bag is opened by the bag opening mechanism. At this time, the bottom of the filling bucket corresponds to the bag opening of the filling bag to realize the filling of the nuts.

[0018] After the nuts are filled, the transmission platform is supported on the filling bag. At this time, the clamping mechanism drives the two clamping arms to rotate toward each other until the clamping frame clamps and straightens the packaging bag. At this time, the bag mouth of the filling bag is clamped by two clamping plates, and then the bag opening mechanism is reset, the bag clamping mechanism releases the filling bag, and finally the slide slides backward, and the transmission platform starts working at the same time until the filling bag is sent to the next station for sealing the bag mouth of the canned bag. In this structure, the bag opening mechanism and the bag clamping mechanism are not the key contents of this mechanism, so they are not specially explained here.

[0019] When the clamping mechanism clamps and straightens the filling bag, the two clamping cylinders simultaneously drive the top of the rotating plate on the same side to rotate outward. During this process, the bottoms of the two rotating plates rotate inward, and the two clamping arms rotate inward synchronously until the two clamping frames clamp the filling bag and the clamping plates clamp the bag opening of the filling bag. The whole process is relatively simple, and during the bag delivery process, the filling bag is always clamped and straightened by the clamping frame, and the bag opening of the filling bag is clamped by the clamping plate to prevent nuts from falling during the bag delivery process.

[0020] As a preferred structure, the connecting plate 6 is provided with a plurality of adjustment holes 10 along the height direction, the clamping frame 7 includes a pair of threaded rods 71, and a clamping plate 72 is provided at the ends of the two threaded rods 71. A pair of locking nuts (not shown in the figure) are provided on the threaded rods 71, and the locking nuts are located on both sides of the connecting plate.

[0021] In this mechanism, the installation height of the clamp can be adjusted according to actual conditions. When the installation height of the clamp needs to be adjusted, specifically: first unscrew the locking nut on the same side and located on the outside of the connecting plate, then the same pair of threaded rods can be removed from the connecting plate, and then the two threaded rods are inserted into the adjustment holes of the corresponding heights, and finally the locking nut is screwed onto the threaded rod until the threaded rod is locked on the connecting plate.

[0022] Further as a preferred structure, a driving wheel 11 and a driven wheel 12 are respectively provided on the side walls of the carrier 1, and a matching belt 13 is sleeved between the driving wheel 11 and the driven wheel 12, the slide 2 is connected to the belt through a connecting block 14, and the carrier is also provided with a sliding motor 15 for driving the driving wheel to rotate.

[0023] When the slide seat needs to slide along the length direction of the carrier, the sliding motor drives the driving wheel to rotate, so that the belt rotates, thereby driving the slide seat to slide.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
