Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging device technology, specifically a packaging device for finished folding chairs. Background Technology
[0002] Folding chairs are characterized by their compact structure and ease of storage and transportation, making them widely used in outdoor leisure, exhibitions, and temporary storage. In the large-scale production process of folding chairs, finished product packaging is a crucial step. Its core lies in reducing the volume of the folding chair to minimize transportation space usage and ensuring structural stability during transport through securing and binding.
[0003] Currently, most common folding chair packaging devices on the market adopt a design mode that separates the compression process from the bundling process. After compression, the folding chairs need to be manually handled or transferred to the bundling area through a complex conveyor mechanism, which leads to a longer production cycle and makes it difficult to meet the continuous needs of assembly line operations. Moreover, when compressing folding chairs, it is impossible to monitor the pressure, which can easily cause excessive pressure to damage the folding chairs, thereby increasing production costs and reducing packaging efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example
[0022] Please see Figures 1 to 3This utility model provides a technical solution for a folding chair finished product packaging device, including a work platform 8, a bracket 7 fixedly connected to the upper left part of the work platform 8, a second electric telescopic rod 6 installed on the upper part of the bracket 7, an upper pressure plate 1 fixedly connected to the lower end of the output rod of the second electric telescopic rod 6, a strapping machine 10 installed between the two brackets 7 on the upper part of the work platform 8, and a lower pressure plate 3 slidably connected to the upper left part of the work platform 8 inside the bracket 7.
[0023] Specifically, the strapping machine 10 is a semi-automatic hot melt strapping machine 10, model KB-508, which includes a strap feeding mechanism, a tightening mechanism and a hot melt cutter. The strapping tape is suitable for a width of 12-19mm, a thickness of 0.5-1.0mm, and is made of PP or PET.
[0024] Please refer to Figure 3. The front and rear parts of the bracket 7 have a sliding groove 2 on the inner side of the bracket 7. The inner side of the sliding groove 2 is slidably connected to the slider 12. The side of the slider 12 near the upper pressure plate 1 is fixedly connected to the upper pressure plate 1.
[0025] Please refer to Figure 1. A first electric telescopic rod 5 is installed on the upper right side of the work platform 8. A push plate 4 is fixedly connected to the left end of the output rod of the first electric telescopic rod 5 in the left direction. The bottom of the push plate 4 slides on the upper part of the work platform 8.
[0026] Please refer to Figure 3. The lower part of the working platform 8 is threaded with an external threaded nail 11 below the lower pressure plate 3. A lower electrode block 14 is provided above the external threaded nail 11, and an upper electrode block 13 is provided below the lower pressure plate 3.
[0027] Specifically, the pitch of the external threaded pin 11 is 1.5mm, the adjustment range is 0-30mm, and both the upper electrode block 13 and the lower electrode block 14 are made of copper with a contact surface size of 20mm×20mm.
[0028] Please refer to Figure 1 to Figure 3 The upper electrode block 13 is connected in series with the control circuit of the strapping machine 10, and the lower electrode block 14 is connected in series with the control circuit of the strapping machine 10.
[0029] Specifically, the control circuit includes a DC24V power supply, a PLC controller (model: S7-200 SMART), and relays.
[0030] Please refer to Figure 1 and Figure 3 Elastic telescopic rods 15 are provided on the lower front and rear sides of the pressure plate 3. The lower part of the elastic telescopic rods 15 is fixedly connected to the working platform 8. The lower part of the working platform 8 is fixedly connected to the support legs 9.
[0031] Specifically, the elastic coefficient of the elastic telescopic rod 15 is 50-80 N / mm, and in its natural state, the upper surface of the pressure plate 3 is flush with the upper surface of the work platform 8.
[0032] During use, rotating the external threaded pin 11 allows it to move up and down via the threaded connection between it and the work platform 8, thereby moving the lower electrode block 14 up and down. The position of the lower electrode block 14 can be determined based on the material of the folding chair. Then, the folding chair is placed on the work platform 8, positioned to the left of the push plate 4. The first electric telescopic rod 5 is then activated, pushing the push plate 4 to the left, which in turn pushes the folding chair to the left, placing it onto the lower pressure plate 3. Finally, the second electric telescopic rod 6 is activated, causing... The second electric telescopic rod 6 pushes the upper pressure plate 1 downward, and the slider 12 slides downward inside the slide groove 2. The upper pressure plate 1 compresses the folding chair and also pushes the lower pressure plate 3 downward to compress the elastic telescopic rod 15. When the upper electrode block 13 and the lower electrode block 14 come into contact, the strapping machine 10 starts to strap the folding chair. After strapping, the second electric telescopic rod 6 drives the upper pressure plate 1 to rise, and the first electric telescopic rod 5 continues to push the strapped folding chair to the left through the push plate 4, so that the strapped folding chair leaves the lower pressure plate 3, thereby completing the packaging of the folding chair.
