Description

Technical Field

[0001] This utility model relates to the field of bag-supporting packaging technology, and more specifically, to a foolproof bag-supporting device. Background Technology

[0002] In automated packaging production, materials are typically fed into the packaging bags below through the inlet. However, because the packaging bags are flexible and prone to collapse, the bag opening is easily closed or rolled up before it is fully opened, causing uneven material feeding, jamming, or spillage, thus affecting bagging efficiency and product quality.

[0003] However, in the existing bag opening process, relying solely on suction cups to open the packaging bag or using air to open the packaging bag can easily lead to problems such as material spillage due to improper positioning, which greatly affects the feeding operation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a foolproof bag-holding device to solve the above problems.

[0005] The present invention adopts the following solution:

[0006] This application provides a foolproof bag-supporting device for installation in the feeding area of ​​a packaging machine. The bag-supporting device includes a base plate with a feeding port at the top, a bag-supporting assembly disposed at the bottom of the base plate, and a power component for linkage with the bag-supporting assembly. The power component and the bag-supporting assembly are connected by a linkage assembly. The bag-supporting assembly is configured to have a bag-supporting state (open to connect the feeding port and the packaging bag below) and a foolproof state (closed to seal the feeding port). The power component acts on the linkage assembly to trigger the bag-supporting assembly to freely switch states. In the bag-supporting state, the bag-supporting assembly can extend into the packaging bag and pull the opening of the packaging bag outward, thereby expanding the opening of the packaging bag so that materials and accessories fed along the feeding port can smoothly enter the packaging bag.

[0007] As a further improvement, the substrate includes a hopper disposed on the front side, the feed inlet being formed at the upper end of the hopper, and the bag support assembly being disposed at the lower end of the hopper.

[0008] As a further improvement, the substrate also includes a longitudinally arranged guide rail, on which the hopper is mounted to move longitudinally relative to the substrate.

[0009] As a further improvement, the base plate also includes a push rod arranged longitudinally on the back side, the push rod being connected to the hopper for pushing the hopper to perform lifting and lowering movements.

[0010] As a further improvement, the power assembly includes a drive rod positioned longitudinally on the hopper, which, when moved downwards, switches the bag-supporting assembly from the bag-supporting state to the foolproof state.

[0011] As a further improvement, the bag support assembly includes swing portions positioned opposite each other on both sides to form an opening and closing spout, the lower ends of the two swing portions being at least partially accommodated within the packaging bag; the two swing portions are hinged together, and the linkage assembly is linked to one of the swing portions.

[0012] As a further improvement, the linkage assembly includes a transmission rod hinged to the output shaft of the drive rod, the transmission rod being connected to an adjacent swing section.

[0013] As a further improvement, the transmission rod is V-shaped, with one end integrally connected to the swing part and the other end having a strip groove. The output shaft of the drive rod is provided with a hinge shaft that can move flexibly within the strip groove.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0015] The foolproof bag-holding device of this application, when no material is fed or the packaging bag is not in place, the bag-holding component is in a foolproof state and closes the feed inlet to avoid the risk of material spillage. When feeding and packaging begin, the power component drives the linkage component, which in turn triggers the bag-holding component to switch to the bag-holding state, automatically opening to form a feeding channel, realizing synchronous extension and opening and closing actions, ensuring that the bag-holding action is coordinated and consistent. Moreover, the bag-holding component can extend into the packaging bag and pull the bag opening outward to fully open the bag opening, making it easy for the material to enter the bag smoothly. Therefore, it can adapt to different specifications of packaging bags, is easy to adjust, and has strong versatility. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0021] Example

[0022] Combination Figures 1 to 3 This embodiment provides a foolproof bag-supporting device for installation in the feeding area of ​​a packaging machine. The device includes a base plate 2 with a feed inlet 1 at the top, a bag-supporting assembly 3 disposed at the bottom of the base plate 2, and a power component 4 for linkage with the bag-supporting assembly 3. The power component 4 and the bag-supporting assembly 3 are connected by a connecting rod assembly 5. The bag-supporting assembly 3 is configured to have a bag-supporting state (open to connect the feed inlet 1 to a packaging bag below, not shown) and a foolproof state (closed to seal the feed inlet 1). The power component 4 acts on the connecting rod assembly 5 to trigger the bag-supporting assembly 3 to freely switch states. In the bag-supporting state, the bag-supporting assembly 3 can extend into the packaging bag and open the bag's opening, thereby expanding the opening of the packaging bag so that materials and accessories fed through the feed inlet 1 can smoothly enter the packaging bag.

[0023] The aforementioned foolproof bag-holding device, when no material is being fed or the packaging bag is not in place, the bag-holding component 3 is in a foolproof state and closes the feed inlet 1 to avoid the risk of material spillage. When feeding and packaging begin, the power component 4 drives the connecting rod component 5, which in turn triggers the bag-holding component 3 to switch to the bag-holding state, automatically opening to form a feeding channel, realizing synchronous extension and opening and closing actions, ensuring that the bag-holding action is coordinated and consistent. Moreover, the bag-holding component 3 can extend into the packaging bag and pull the bag opening outward to fully open the bag opening, making it easy for the material to enter the bag smoothly. Thus, it can adapt to different specifications of packaging bags, is easy to adjust, and has strong versatility.

[0024] like Figure 2 and Figure 3As shown, in this embodiment, the substrate 2 includes a hopper 6 disposed on the front side, a feed inlet 1 correspondingly formed at the upper end of the hopper 6, and a bag-supporting assembly 3 correspondingly disposed at the lower end of the hopper 6. Clearly, with the hopper 6 disposed on the front side and the feed inlet 1 formed at the upper end of the hopper 6, material can smoothly fall into the hopper 6 through the feed inlet 1. The bag-supporting assembly 3, disposed at the lower end of the hopper 6, can extend into the packaging bag and pull the bag opening outwards, fully opening the packaging bag to facilitate the smooth entry of material into the packaging bag, ensuring bagging efficiency and bagging stability.

[0025] It is worth mentioning that the bag support assembly 3 can close the feed inlet 1 when the packaging bag is not in place, preventing the material from being accidentally fed in, thereby avoiding waste and pollution and improving production safety. Through the reasonable layout of the base plate 2, hopper 6 and bag support assembly 3, the smooth guidance of materials from feeding to bag entry is achieved, which is particularly suitable for the feeding process of high-speed automatic packaging lines, improving production efficiency and reliability.

[0026] Specifically, the base plate 2 further includes a longitudinally arranged guide rail 7, and the hopper 6 is mounted on the guide rail 7 to move longitudinally relative to the base plate 2. This facilitates the vertical adjustment of the relative positions of the hopper 6 and the bag support assembly 3 with the packaging bag, adapting to different specifications of packaging bags or production process requirements, and improving the adaptability and flexibility of the bagging device.

[0027] Furthermore, the base plate 2 also includes a push rod 8 longitudinally disposed on the back side, which is connected to the hopper 6 and used to push the hopper 6 to perform lifting and lowering movements. This enables the height adjustment of the hopper 6, ensuring that the material feeding and bag-opening actions are matched at the same height, thereby improving the operational accuracy of the device.

[0028] like Figure 3 As shown, in this embodiment, the power assembly 4 includes a drive rod 9 vertically positioned on the hopper 6. Moving the drive rod 9 downwards switches the bag-supporting assembly 3 from the bag-supporting state to the foolproof state. Through the linkage between the drive rod 9 and the bag-supporting assembly 3, the device automatically closes the inlet 1 when the packaging bag is not in place, improving the foolproof protection effect and preventing accidental material feeding or device damage.

[0029] It is worth noting that the push rod 8 is arranged upwards and the drive rod 9 is arranged downwards, with both acting on the upper hopper 6 and the lower bag support assembly 3, respectively. Furthermore, both the push rod 8 and the drive rod 9 are selected as electric rods, direct push rods, direct drive components, etc.

[0030] like Figure 1 and Figure 3As shown, in this embodiment, the bag-supporting assembly 3 includes two opposing swing portions 10 forming an opening and closing spout. At least a portion of the lower ends of the two swing portions 10 are housed within the packaging bag. The two swing portions 10 are hinged together, and the connecting rod assembly 5 is linked to one of the swing portions 10. Thus, the two swing portions 10 are hinged together to form an openable and closable "spout-shaped structure," with at least a portion of the lower end extending into the packaging bag. When driven by the power assembly 4, the two swing portions 10 open outwards to support and expand the opening of the packaging bag from the inside, allowing the bag opening to fully expand and facilitating the smooth entry of materials into the bag. Through the linkage transmission between the connecting rod assembly 5 and the swing portions 10, the synchronous opening and closing of the bag-supporting assembly 3 can be achieved, resulting in coordinated action and sensitive response.

[0031] It should be noted that the two opposing swing parts 10 of the hinge are similar to a scissor-type opening and closing structure, so as to freely switch between the bag-supporting state after opening and the foolproof state after closing.

[0032] like Figure 3 As shown, in this embodiment, the linkage assembly 5 includes a transmission rod 11 hinged to the output shaft of the drive rod 9, and the transmission rod 11 is connected to the adjacent swing part 10. On one hand, the output shaft of the drive rod 9 is connected to the transmission rod 11 via a hinge, allowing power to be smoothly transmitted to the bag-supporting assembly 3 when the drive rod 9 moves up and down or reciprocates. On the other hand, the transmission rod 11 is directly connected to the adjacent swing part 10, enabling the swing part 10 to swing around the hinge point quickly, thus realizing the opening and closing action of the bag-supporting assembly 3.

[0033] The transmission rod 11 is V-shaped, with one end integrally connected to the swing part 10 and the other end having a slot 12. The output shaft of the drive rod 9 has a hinge pin 13 that can move flexibly within the slot 12. The V-shaped transmission rod 11 is integrally connected to the swing part 10, allowing it a certain range of motion during operation to adapt to angle changes during the opening and closing of the bag support assembly 3, thus ensuring the continuity and smoothness of the transmission path. Furthermore, the slot 12 at the other end of the transmission rod 11 and the hinge pin 13 sliding within the slot 12 on the output shaft of the drive rod 9 enable variable displacement and angle compensation within a specified range during the driving process.

[0034] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
