Description

Technical Field

[0001] This application relates to the field of packaging bag processing technology, and in particular to a packaging bag opening device. Background Technology

[0002] After processing, products such as edamame will enter the packaging stage. As the final step in the product production process, the efficiency of packaging directly affects the production capacity of the product.

[0003] Before packing the product into the packaging bag, the bag needs to be opened. Currently, this is usually done manually by opening the packaging bag and then packing the product into it. However, manually opening the packaging bag is a complex and inefficient process, especially in scenarios involving large-scale continuous production. The high degree of manual involvement leads to high labor intensity and a high risk of errors.

[0004] In view of the aforementioned technologies, the inventors believe there is a need to provide a packaging bag opening device. Utility Model Content

[0005] In order to automate the opening of packaging bags and improve the packaging efficiency of products, this application provides a packaging bag opening device.

[0006] The packaging bag opening device provided in this application adopts the following technical solution:

[0007] A packaging bag opening device includes a transfer tray, a plurality of clamping assemblies mounted on the transfer tray for clamping the packaging bag, and a bag opening assembly for opening the packaging bag. The bag opening assembly includes a bag opening frame, two bag opening arms mounted on the bag opening frame and arranged opposite to each other, suction cup assemblies disposed at the ends of the bag opening arms, and a first driving member for driving the bag opening arms to move closer or further apart from each other.

[0008] By adopting the above technical solution, the packaging bag opening device can automatically open packaging bags, effectively replacing manual operation. The transfer tray, in conjunction with the clamping and opening components, can stably clamp and open packaging bags during continuous production, significantly improving packaging efficiency and reducing labor intensity. Specifically, the relative arrangement of the opening arms, combined with the driving function of the first drive component, allows the opening arms to precisely move closer or further apart, ensuring the packaging bag is fully opened. The suction cup component further enhances the gripping and fixing effect on the bag opening, improving operational stability. The entire device achieves automated bag opening, improving product packaging efficiency.

[0009] Optionally, the suction cup assembly includes a fixing member detachably mounted to the end of the bag opening arm and a suction cup component mounted on the fixing member at the end away from the bag opening arm.

[0010] By adopting the above technical solution, the suction cup assembly is detachably connected to the bag opening arm via a fixing component, and the suction cup is installed at the end of the fixing component furthest from the bag arm. This method makes the installation and replacement of the suction cup assembly more convenient, allowing for quick replacement of worn or damaged suction cups during long-term use, thus ensuring the normal operation of the device. At the same time, the detachable design also facilitates the selection of appropriate suction cups based on the material and specifications of different packaging bags, improving the adaptability and working efficiency of the device.

[0011] Optionally, each of the two bag-opening arms is provided with a connecting post, and the bag-opening assembly further includes a first return spring with both ends respectively connected to the connecting post.

[0012] By adopting the above technical solution, the first return spring enables the two bag-opening arms to automatically return to their initial positions after completing the opening action, thereby improving the automation level and work efficiency of the device. Specifically, the connecting column provides a stable mounting point for the first return spring, and the elastic restoring force of the first return spring ensures the precise reset of the bag-opening arms, reduces operational errors caused by manual intervention, and further improves the stability and reliability of the bag-opening process.

[0013] Optionally, one of the bag-opening arms has a drive gear connected to the first drive member at one end near the bag-opening frame, and the other bag-opening arm has a driven gear meshing with the drive gear.

[0014] By adopting the above technical solution, the relative movement between the bag-opening arms is achieved by the meshing transmission of the driving gear and the driven gear. This structural design not only ensures the synchronization and stability of the bag-opening arms' movements but also effectively improves the operating accuracy of the bag-opening assembly. Compared with the traditional direct drive method, gear transmission can maintain high reliability under complex working conditions, thereby reducing the equipment failure rate and further improving the consistency and efficiency of the bag-opening operation.

[0015] Optionally, the clamping assembly includes two sets of transfer rods disposed on the transfer tray, clamping claws mounted on the ends of the transfer rods, and a second driving member for driving the transfer rods to rotate.

[0016] By adopting the above technical solution, the clamping assembly includes two sets of transfer rods, clamping claws installed at the ends of the transfer rods, and a second driving component that drives the transfer rods to rotate. This enables stable clamping and precise positioning of the packaging bag. The second driving component drives the transfer rods to rotate, achieving precise adjustment of the clamping claws. When the bag opening assembly opens the packaging bag, the two sets of transfer rods move closer to each other, which helps to stably clamp the packaging bag after it is opened.

[0017] Optionally, a fixing collar is provided at the end of the transfer rod away from the clamping claw, the second driving member is fixed to the bottom of the transfer disk, and the fixing collar is fixedly sleeved on the output shaft of the second driving member.

[0018] By adopting the above technical solution, the fixed collar allows the transfer rod to be securely connected to the output shaft of the second drive component, thereby achieving precise rotation of the transfer rod. This connection method not only improves the stability of the clamping assembly but also ensures the accurate positioning of the packaging bag during the transfer process. Furthermore, the design of fixing the second drive component to the bottom of the conveyor tray optimizes the spatial layout, making the overall structure more compact and rational, and facilitating maintenance and assembly.

[0019] Optionally, the clamping assembly further includes a second return spring with both ends connected to the two sets of transfer rods respectively.

[0020] By adopting the above technical solution, the second return spring is set in the clamping assembly, which enables the two sets of transfer rods to return to their initial positions after they approach each other and the bagging is completed. This improves the automation level and working efficiency of the device, and further enhances the stability and reliability of the bag opening process.

[0021] The components are connected in a flexible manner. This design effectively improves the stability of the clamping components and reduces the displacement of the transfer rod due to external vibration or improper operation when clamping the packaging bag, thereby ensuring that the packaging bag is accurately clamped.

[0022] Optionally, the packaging bag opening device further includes a support assembly and a third drive component located on the transfer tray for driving the support assembly to move up and down.

[0023] By adopting the above technical solution, since the third driving component can drive the support component to rise and rotate, the support component can be inserted into the packaging bag after the bag opening component opens the packaging bag, which helps to stabilize the inner wall of the packaging bag and can transfer the opened packaging bag to the bagging process.

[0024] Optionally, the support assembly includes a support rod for insertion into a packaging bag, a support bracket for mounting the support rod, an air inlet pipe disposed on the support rod for blowing air into the packaging bag, and a fourth drive member for driving the support rod to move radially along the transfer tray.

[0025] By adopting the above technical solution, the specific composition of the support component is disclosed. The support component includes a support rod, a support bracket, an air inlet pipe, and a fourth driving component. After the support rod is inserted into the packaging bag, the air inlet pipe can blow air into the packaging bag to make the packaging bag in an inflated state, which facilitates the fourth driving component to drive the support rod to move radially along the transfer plate, so that the support rod is close to the inner wall of the packaging bag, thereby facilitating the subsequent loading of the product into the packaging bag.

[0026] Optionally, the support rod includes a support portion for abutting against the inner wall of the packaging bag, a guide portion connected to the top of the support portion, and clearance portions at both ends horizontally connected to the guide portion and the support bracket, respectively, wherein the guide portion is inclined downward toward the inside of the packaging bag.

[0027] By adopting the above technical solution, the specific structure of the support component is disclosed. The support rod includes a support part, a guide part, and a clearance part. The support part can ensure that the packaging bag is fully unfolded and avoid the bag opening from collapsing or deforming, thereby improving the stability of subsequent bagging. The guide part is inclined downward towards the inside of the packaging bag, which helps to put the product into the packaging bag later. The clearance part provides top space for putting the product into the packaging bag, making it convenient to put the product into the packaging bag.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. A packaging bag opening device, which achieves automatic opening and stable clamping of packaging bags through the coordinated operation of a transfer tray, a clamping component and an opening component, thereby improving product packaging efficiency, reducing manual intervention and effectively reducing labor intensity;

[0030] 2. By detachably installing a fixing part and a suction cup part at the end of the bag opening arm of the suction cup assembly, the installation and replacement of the suction cup assembly is more convenient. During long-term use, worn or damaged suction cup parts can be quickly replaced, thereby ensuring the normal operation of the device.

[0031] 3. By setting a first return spring between the two bag-opening arms, the two bag-opening arms can automatically return to their initial positions after completing the opening action, thereby improving the automation level and working efficiency of the device. Attached Figure Description

The second return spring 25 helps the two sets of transfer rods 22 return to their initial positions after they approach each other and the bag is filled. The fixing collars 21 are fixedly sleeved on the output shaft of the second driving member 24, so that the second driving member 24 drives the fixing collars 21 to rotate, thereby driving the transfer rods 22 and the clamping claws 23 to rotate. The clamping claws 23 on the two sets of transfer rods 22 approaching each other helps to stably clamp the packaging bag after it is opened. In this embodiment, the second driving member 24 is a cylinder.
