Technical Field
[0001] This utility model relates to a foam pushing device, and more particularly to a foam pushing device with a foam buffer conveying mechanism, belonging to the field of case packing machine technology. Background Technology
[0002] A case packer is a device used to automatically or semi-automatically pack unpackaged or small-packaged products into transport packaging (such as corrugated cardboard boxes, plastic boxes, etc.). Its main functions include automatic packing, sealing, and strapping.
[0003] During the packing process, foam is often packed together with the product into the box. The main reasons for including foam during packing are as follows:
[0004] I. Cushioning and Protection: Foam, especially EVA foam, has excellent cushioning properties. During packing, foam can absorb and dissipate the impact and vibration energy of the goods, thereby maintaining the relative stability of the goods during transportation and reducing the risk of damage caused by external factors such as bumps and collisions.
[0005] II. Filling and Securement: During the packing process, gaps often exist between items and between items and the carton walls. Foam can be placed in these gaps to fill them and prevent items from moving or shifting inside the box. This not only protects the items but also improves the tightness and stability of the packaging.
[0006] 3. Moisture and dust protection: Some foam materials also have good moisture and dust protection properties, which can protect items from the influence of the external environment to a certain extent.
[0007] Therefore, the main reason for including foam in packaging is its advantages in cushioning and protection, filling and fixing, flexible adaptation, and moisture and dust protection. These advantages make foam an indispensable material in the packaging process.
[0008] In one existing foam packing method, the foam is pushed into the packaging box by a foam pushing device, such as... Figure 1 As shown, the existing foam pushing device includes a lifting plate 1 and a horizontal pushing plate 2 located above the lifting plate 1. A stack of foam 3 is loaded on the lifting plate 1. During operation, the lifting plate 1 is raised a certain distance, thereby driving one or more foam 3 located at the upper position of the stack of foam 3 to rise to the pushing height of the horizontal pushing plate 2. Then, the horizontal pushing plate 2 is controlled to push the one or more foam 3 along the channel 4 for packing.
[0009] Therefore, in this foam packing method, a stack of foam 3 needs to be loaded onto the lifting plate 1 before the foam can be pushed. In existing technology, the foam is often manually stacked and loaded onto the lifting plate 1, but this increases the workload of workers and reduces efficiency. To improve the loading efficiency of foam, one existing method is to use a conveyor belt for loading, such as... Figure 2 As shown, a conveyor belt 5 is provided on one side of the lifting plate 1. Stacked foam 3 is placed on the conveyor belt 5. When a stack of foam 3 on the lifting plate 1 is used up, the next stack of foam 3 is conveyed to the lifting plate 1 by the conveyor belt 5 for continued use. This process is repeated until the entire packing work is completed.
[0010] While this method of using conveyor belts to transport multiple stacks of foam improves the loading efficiency of foam to some extent, the relatively light weight of foam and the considerable height of the stacked foam make it difficult to ensure the stability of the stacked foam during the conveyor belt transport process. Affected by various external factors, the stacked foam often collapses during transport, which in turn reduces the overall loading efficiency of foam and increases the labor intensity of workers.
[0011] In summary, designing a foam pushing device that can both ensure rapid loading of stacked foam and maintain the stability of the stacked foam during loading to prevent collapse, thereby improving foam loading efficiency and overall foam packing efficiency while reducing the labor intensity of workers, is an urgent technical problem to be solved.

The piston rod of the telescopic power cylinder is connected to the telescopic plate, so that the telescopic plate can move up and down in the vertical direction under the drive of the telescopic power cylinder.
[0023] The beneficial effects of this utility model are as follows: This utility model utilizes the cooperation between the foam insert plate and the foam buffer platform to form a foam buffer space, which limits and guides each stack of foam during movement, thereby ensuring that each stack of foam will not collapse during the process of moving from the foam buffer platform to the foam lifting tray. This allows for rapid loading of stacked foam while ensuring the stability of the stacked foam during loading, preventing collapse and improving the loading efficiency and overall foam packing efficiency, while reducing the labor intensity of workers. By setting a door panel with baffles, this utility model adds a limiting and guiding surface using the baffles. The U-shaped space of the foam insert plate and the baffles provide limiting and guiding on four sides of the foam stack, further ensuring the limiting and guiding of each stack of foam during movement and improving the stability of the foam stack during movement. By designing the foam box moving plate as a telescopic plate structure, the practicality of this utility model is increased, making it more suitable for the needs of actual working conditions.

[0050] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1:
[0051] like Figure 3 and Figure 4 As shown, a foam pushing device with a foam buffer conveying mechanism includes a foam lifting mechanism 6 with a foam lifting tray 611, a foam feeding drive mechanism 7 with a foam feeding moving plate 711, and a foam buffer conveying trough 8. The foam buffer conveying trough 8 is located above the foam lifting mechanism 6. The foam lifting tray 611 can move up and down under the drive of the foam lifting mechanism 6, so that the foam placed on the foam lifting tray 611 can move to one end of the foam buffer conveying trough 8. The foam feeding moving plate 711 is located above the foam buffer conveying trough 8, and the foam feeding moving plate 711 can move back and forth along the length of the foam buffer conveying trough 8 under the drive of the foam feeding drive mechanism 7. During operation, the foam lifting tray 611 is at the bottom position. At this time, a stack of foam is placed on the foam lifting tray 611. Then, the foam lifting mechanism 6 drives the foam lifting tray 611 to move upward, so that one or more foams in the upper position of the stack of foam placed on the foam lifting tray 611 rise to one end of the foam buffer conveying groove 8. Then, the foam box entry drive mechanism 7 drives the foam box entry moving plate 711 to move the one or more foams from the foam lifting tray 611 to the foam buffer conveying groove 8. Then, the one or more foams continue to move along the foam buffer conveying groove 8 to the carton for packing.
[0052] The foam buffer conveying mechanism is located on one side of the foam lifting mechanism 6. The foam buffer conveying mechanism includes a support frame 9, a foam buffer platform 10 mounted on the support frame 9, and a foam toothed plate 11 located on one side of the foam buffer platform 10. The foam toothed plate 11 is slidably connected to the support frame 9 via a toothed plate moving mechanism. The teeth of the foam toothed plate 11 are horizontally oriented, thus forming multiple foam buffer spaces between the foam toothed plate 11 and the foam buffer platform 10. Each foam buffer space contains a stack of foam. The height of the foam buffer platform 10 is the same as the height of the foam lifting tray 611 at the lower position. During operation, the toothed plate moving mechanism moves the foam toothed plate 11 along the foam buffer platform 10, thereby sequentially moving the stack of foam in each foam buffer space onto the foam lifting tray 611.
[0053] like Figure 5 As shown, the foam insert plate 11 is serrated and includes an insert plate base plate 111 and a plurality of toothed plates 112 vertically arranged on the insert plate base plate 111. Two adjacent toothed plates 112 and the insert plate base plate 111 form a U-shaped space 12, and the U-shaped opening of the U-shaped space 12 is oriented horizontally.
[0054] like Figure 6 As shown, when the foam insert plate 11 moves to the position above the foam buffer platform 10 under the drive of the insert plate moving mechanism, the foam buffer space 13 is formed between the platform of the foam buffer platform 10 and each U-shaped space 12. Since there are multiple U-shaped spaces 12, there are also multiple foam buffer spaces 13. The multiple foam buffer spaces 13 are distributed sequentially along the length direction of the foam buffer platform 10.
[0055] The specific working process of this embodiment is as follows: Let the length direction of the rectangular foam buffer platform 10 be the X direction, then the width direction of the rectangular foam buffer platform 10 is the Y direction. For example... Figure 7 and Figure 8 As shown, before operation, a stack of foam 3 is placed in each foam buffer space 13. In this embodiment, three stacks of foam, A, B, and C, are placed. During operation, the foam lifting mechanism 6 is used to lower the foam lifting tray 611 to a position flush with the surface of the foam buffer platform 10. Figure 9 and Figure 10 As shown, the toothed plate moving mechanism is then controlled to move the foam toothed plate 11 along the length direction (X direction) of the foam buffer platform 10, moving stack A of foam onto the foam lifting tray 611. At this time, stack B of foam moves to the original position of stack A, and stack C of foam moves to the original position of stack B. Figure 11As shown, the movement mechanism of the toothed plate is then controlled to move the foam toothed plate 11 along the width direction (Y direction) of the foam buffer platform 10, causing the foam toothed plate 11 to be extracted from the foam in stacks A, B, and C, leaving the foam in stack A alone on the foam lifting tray 611. This avoids interference and collision between the foam lifting tray 611 and the foam toothed plate 11 during lifting and lowering. At this time, the foam lifting tray 611 can be controlled to rise and cooperate with the foam box moving plate 711 to pack the foam in stack A on the foam lifting tray 611. During the packing process of the foam in stack A, the foam toothed plate 11 is controlled to move along the length direction (X direction) of the foam buffer platform 10 back to its original position. Figure 12 and Figure 13 As shown, after all the foam in stack A on the foam lifting tray 611 is packed, the foam lifting tray 611 is lowered again until it is flush with the surface of the foam buffer platform 10. Then, the foam insert plate 11 is moved along the width direction (Y direction) of the foam buffer platform 10, inserting the foam insert plate 11 into the foam in stacks B and C, so that the foam in stacks B and C is located in the foam buffer space 13 on the foam insert plate 11. Figure 14 As shown, the foam insert plate 11 is then controlled to move along the length direction (X direction) of the foam buffer platform 10, moving the B stack of foam onto the foam lifting tray 611. At this time, the C stack of foam moves to the original position of the B stack of foam. Figure 15 As shown, the foam insert plate 11 is then moved along the width direction (Y direction) of the foam buffer platform 10, causing the foam insert plate 11 to be pulled out from the foam in stacks B and C, leaving the foam in stack B alone on the foam lifting tray 611. At this point, the foam in stack B on the foam lifting tray 611 can be packed into boxes. This operation is repeated until all the foam in stacks A, B, and C are sequentially transported to the foam lifting tray 611 for packing.
[0056] This embodiment utilizes a foam insert plate and a foam buffer platform to form a foam buffer space, which limits and guides each stack of foam during movement. This ensures that each stack of foam will not collapse during the process of moving from the foam buffer platform to the foam lifting tray. This allows for rapid loading of stacked foam while maintaining its stability during loading, preventing collapse and improving the loading efficiency and overall foam packing efficiency, while reducing the labor intensity of workers.
[0057] like Figure 16As shown, the toothed plate moving mechanism includes a foam tooth front and rear movement cylinder 14 mounted on the mechanism support 9, a foam toothed plate support 16 slidably connected to the mechanism support 9 via a foam tooth front and rear movement linear guide rail 15, and a foam toothed left and right movement cylinder 17 mounted on the foam toothed plate support 16. The foam toothed plate 11 is slidably connected to the foam toothed plate support 16 via a foam toothed left and right movement linear guide rail 18. The foam toothed front and rear movement cylinder 14 is arranged along the width direction (Y direction) of the foam buffer platform 10, and its piston rod is connected to the foam toothed plate support 16, so that the foam toothed plate support 16 can move back and forth along the Y direction under the action of the foam toothed front and rear movement cylinder 14. The foam toothed left and right movement cylinder 17 is arranged along the length direction (X direction) of the foam buffer platform 10, and its piston rod is connected to the foam toothed plate support 16, so that the foam toothed plate 11 can move back and forth along the X direction under the action of the foam toothed left and right movement cylinder 17. Through the above structural design, the toothed plate moving mechanism forms a two-dimensional XY moving mechanism. During operation, the movement of the foam toothed plate 11 in both the X and Y directions is achieved by the driving of the toothed plate moving mechanism, which further facilitates the sequential transport of multiple stacks of foam. In this embodiment, the front and rear movement cylinders and the left and right movement cylinders of the foam toothed plate are all pneumatic cylinders, but other types of cylinders can also be used.
[0058] like Figure 17 As shown, a sensor 19 is provided on the foam buffer platform 10 and within each foam buffer space 13. The sensor 19 is used to sense whether each foam buffer space 13 is filled with foam. In this embodiment, the sensor 19 can be a photoelectric sensor. Multiple through holes 20 are provided on the foam buffer platform 10, and the sensor 19 is installed on the bottom surface of the foam buffer platform 10 corresponding to the through holes 20.
[0059] like Figure 3 As shown, a position detection switch 22 is provided on the foam insert plate 11 and at the upper position within each U-shaped space 12. When the foam is stacked in each U-shaped space 12, the position detection switch 22 can be used to detect the height position of each stack of foam, thereby ensuring that the number of stacks of foam meets the working requirements. Example 2:
[0060] like Figure 18 and Figure 19As shown, compared with Embodiment 1, the difference lies in that: a rotatably connected door plate 20 is also provided on the mechanism support 9 and at the U-shaped opening of the U-shaped space 12 of the foam insert plate 11. A baffle 21 is provided on the door plate 20, and the baffle 21 is provided on the inner side of the door plate 20. When filling foam, the door plate 20 is opened first, and then three stacks of foam A, B, and C can be filled into the U-shaped space 12. When working, the door plate 20 is closed first. At this time, the baffle 21 blocks the U-shaped opening of the U-shaped space 12, and limits and guides the three stacks of foam A, B, and C on the other side during their movement. In Embodiment 1, the foam stack was mainly guided and limited on three sides by the U-shaped space of the foam insert plate during movement. In this embodiment, an additional guiding and limiting surface is added by using a baffle. That is, in this embodiment, the U-shaped space of the foam insert plate and the baffle are used to guide and limit the foam stack on four sides. This further ensures the guidance and limiting of each stack of foam during movement, and improves the stability of the foam stack during movement. Example 3:
[0061] Compared with Embodiment 1, the difference is that the foam box moving plate 711 is a telescopic plate structure, which can extend and retract in the vertical direction.
[0062] like Figures 20 to 24 As shown, during operation, when the foam box moving plate 711 pushes one side of the foam 3 to move the foam 3 to a certain position on the foam buffer conveying trough 8, due to various unforeseen reasons, it may be necessary to reverse the foam 3 from that position back onto the foam lifting tray 611. If the foam box moving plate 711 cannot extend or retract, the foam 3 cannot be retracted. However, in this embodiment, the foam box moving plate 711 can be shortened first to avoid the foam 3, then moved to the other side of the foam 3, and then extended to push the foam 3 back onto the foam lifting tray 611. This design increases the practicality of the device and better meets the needs of actual working conditions.
[0063] like Figure 25 As shown, the foam box-entry moving plate 711 includes a moving plate body 7111 and a telescopic plate 7112. The moving plate body 7111 is connected to the foam box-entry driving mechanism 7. Under the action of the foam box-entry driving mechanism 7, the moving plate body 7111 can move back and forth in the horizontal direction. A telescopic power cylinder 23 is provided on the moving plate body 7111. The piston rod of the telescopic power cylinder 23 is connected to the telescopic plate 7112, so that the telescopic plate 7112 can move up and down vertically under the action of the telescopic power cylinder 23. In this embodiment, the telescopic power cylinder 23 can be a cylinder.
[0064] In summary, this invention utilizes the cooperation of a foam insert plate and a foam buffer platform to form a foam buffer space, providing limiting and guiding for each stack of foam during movement. This ensures that each stack of foam does not collapse during its movement from the foam buffer platform to the foam lifting tray. This allows for rapid loading of stacked foam while maintaining its stability during loading, preventing collapse and improving loading efficiency and overall foam packing efficiency, while reducing worker workload. By incorporating a door panel with baffles, this invention adds a limiting and guiding surface. The U-shaped space of the foam insert plate and the baffles provide limiting and guiding for the foam stacks on all four sides, further ensuring the stability of each stack during movement. Designing the foam loading and unloading platform as a telescopic structure increases the practicality of this invention and better meets the needs of actual working conditions.

Those skilled in the art can make various changes or modifications without departing from the spirit and scope of this utility model. Therefore, all equivalent technical solutions should also fall within the protection scope of this utility model, which is defined by the claims.
