Description

Technical Field

[0001] This application belongs to the field of packaging machines, and particularly relates to a vibrating blanking device for a packaging machine. Background Art

[0002] In the vast field of the packaging industry, ensuring the ideal compactness and uniform distribution of materials during the packaging process is crucial for enhancing the appearance quality of products, reducing transportation losses, and optimizing storage space.

[0003] Traditional packaging machines generally use the structure of a beating plate to achieve the compact arrangement of materials in the packaging container. The original intention of this design is to reduce the gaps between materials through mechanical vibration, thereby enhancing the tightness of the packaging. However, in practical applications, on the one hand, the beating plate applies force to the packaging bag from both sides, which easily causes the packaging bag to fall off the machine clamp, resulting in the scrapping of the packaged bag. On the other hand, since the installation position of the beating plate on the traditional packaging machine is often fixed and difficult to adjust flexibly, this directly limits its adaptability and vibration effect under different packaging requirements. Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a vibrating blanking device for a packaging machine to solve the technical problems of poor flexibility in use and easy bag dropping of the vibrating blanking device in the prior art.

[0030] Please refer to Figures 1 to 3 , and a vibration feeding device for a packaging machine provided by an embodiment of this application will be described hereinafter. This vibration feeding device for a packaging machine includes a frame table board 101, a lifting shaft 102, an adjusting rod 103, a connecting rod 104, a tray 105, and a vibrator 106. Among them:

[0031] The lifting shaft 102 is vertically connected to the frame table board 101 and can lift relative to the frame table board 101 along its own axis; the adjusting rod 103 is sleeved on the lifting shaft 102 and can move relative to the lifting shaft 102 along the axis of the lifting shaft 102 and can also rotate relative to the lifting shaft 102 around the central axis of the lifting shaft 102. Here, it can be understood that when the adjusting rod 103 is adjusted to a proper position by moving in the axial and circumferential directions of the lifting shaft 102, the adjusting rod 103 can be fixed to the lifting shaft 102 through a fastener. In this way, the position of the adjusting rod 103 during operation is controlled by the lifting shaft 102; the connecting rod 104 has a first connecting arm 141 and a second connecting arm 142 that are perpendicularly connected to each other. The first connecting arm 141 is connected to the adjusting rod 103 and is parallel to the lifting shaft 102, and the second connecting arm 142 is perpendicular to the lifting shaft 102; the tray 105 is sleeved on the second connecting arm 142 and can move relative to the second connecting arm 142 along the axis of the second connecting arm 142; the vibrator 106 is connected to the tray 105 and is used to vibrate the tray 105. Similarly, it can be understood that after the tray 105 is adjusted to a proper position by moving on the second connecting arm 142, the tray 105 can also be relatively fixed to the second connecting arm 142 through a fastener.

[0032] According to the above structure provided in this embodiment, the vibration blanking device for the packaging machine provided in this embodiment is installed below the feeding station of the bag - type packaging machine. When the machine clamp of the packaging machine transfers an empty packaging bag to the feeding station and the feeding assembly of the packaging machine adds materials into the packaging bag 114, the tray 105 rises and the vibrator 106 vibrates the packaging bag 114 through the tray 105 at a low amplitude and high frequency to hold the bottom of the packaging bag 114, so that the materials are quickly compacted in the packaging bag 114. Among them, since the lifting shaft 102 can lift relative to the machine frame platen 101 along its own axis, and the adjusting rod 103 sleeved on the lifting shaft 102 can move relative to the lifting shaft 102 along the axis of the lifting shaft 102 and can rotate relative to the lifting shaft 102 around the central axis of the lifting shaft 102, the connecting rod 104 connected to the adjusting rod 103 can flexibly move following the adjusting rod 103, and make the tray 105 connected to the connecting rod 104 and the vibrator 106 connected to the tray 105 move to different positions more flexibly in space. In addition, since the tray 105 itself can also move relative to the connecting rod 104 along the axis of the second connecting arm 142, this can make the vibration blanking device for the packaging machine provided in this embodiment form a more flexible adjustment effect, far superior to the prior art.

[0033] In another embodiment of the present application, please refer to Figures 1 to 3 , at least two groups of connecting rods 104, trays 105 and vibrators 106 are correspondingly provided, and all the connecting rods 104 are connected to the same adjusting rod 103. According to the above structure provided in this embodiment, at least two groups of connecting rods 104, trays 105 and vibrators 106 can make the vibration blanking device for the packaging machine provided in this embodiment applicable to packaging bags 114 of different specifications and form a better vibration effect. In addition, several connecting rods 104 connected to the same adjusting rod 103 can move synchronously along the axis of the lifting shaft 102 through the adjusting rod 103, which is beneficial to further improving the adjustment flexibility of the vibration blanking device for the packaging machine in this embodiment.

[0034] In another embodiment of the present application, please refer to Figures 1 to 3 , the vibration blanking device further includes a sliding bearing 107 connected to the machine frame platen 101, and the lifting shaft 102 is slidably connected to the machine frame platen 101 through the sliding bearing 107. According to the above structure provided in this embodiment, the sliding bearing 107 connected to the machine frame platen 101 can make the lifting shaft 102 slide relative to the machine frame platen 101 more stably and smoothly, which is beneficial to further improving the adjustment flexibility of the vibration blanking device for the packaging machine in this embodiment.

[0035] In another embodiment of the present application, please refer to Figures 1 to 3, the vibrating blanking device further includes a sealing ring 108 sleeved on the lifting shaft 102. The sealing ring 108 abuts against the sliding bearing 107 to form a sealed connection between the lifting shaft 102 and the sliding bearing 107. According to the above structure provided in this embodiment, the sealing ring 108 sleeved on the lifting shaft 102 can prevent dust and impurities from entering the inside of the sliding bearing 107 by abutting against the sliding bearing 107, which is beneficial to significantly increase the service life of the vibrating blanking device for the packaging machine in this embodiment.

[0036] In another embodiment of the present application, please refer to Figures 1 to 3 , the vibrating blanking device further includes a fixed seat 109 connected to the frame platen 101 and a cylinder 110 installed on the fixed seat 109; the lifting shaft 102 is connected to the output end of the cylinder 110 and can be driven by the cylinder 110. According to the above structure provided in this embodiment, the cylinder 110 connected to the fixed seat 109 can drive the lifting shaft 102 to stably lift relative to the frame platen 101. In this way, after the packaging bag 114 is filled with materials, the cylinder 110 drives the lifting shaft 102 to lower the tray 105 to avoid interference with the path of the transfer station of the packaging bag 114. When the feeding component of the packaging machine fills the packaging bag 114 with materials, the cylinder 110 drives the tray 105 to hold the packaging bag 114 to prevent the packaging bag 114 from falling off the machine clamp of the packaging machine when vibrating the materials, which is beneficial to further improve the adjustment flexibility of the vibrating blanking device for the packaging machine in this embodiment.

[0037] In another embodiment of the present application, please refer to Figures 1 to 3 , the vibrating blanking device further includes a guide sleeve 111 connected to the fixed seat 109 and a guide rod 112 slidably connected to the guide sleeve 111; the lifting shaft 102 is connected to the guide rod 112, and the sliding direction of the guide rod 112 relative to the guide sleeve 111 is parallel to the axial direction of the lifting shaft 102. According to the above structure provided in this embodiment, the lifting shaft 102 and the guide rod 112 are fixedly connected through a connecting plate 113. In this way, the guide rod 112 connected to the lifting shaft 102 can, on the one hand, prevent the lifting shaft 102 from rotating around its own central axis by connecting with the guide sleeve 111, and on the other hand, can also provide sliding guidance for the lifting of the lifting shaft 102 relative to the frame platen 101, which is beneficial to further improve the adjustment flexibility of the vibrating blanking device for the packaging machine in this embodiment.

[0038] In another embodiment of the present application, please refer to Figures 1 to 3, the lifting shaft 102 penetrates through the machine frame platen 101 so that the tray 105 and the cylinder 110 are located on both sides of the machine frame platen 101. According to the above structure provided in this embodiment, the tray 105 and the cylinder 110 being arranged on both sides of the machine frame platen 101 can avoid mechanical interference between the two, which is beneficial to further improving the adjustment flexibility of the vibration feeding device for the packaging machine in this embodiment.

[0039] The foregoing is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
