Description

Technical Field

[0001] This utility model relates to the field of container bag processing technology, and in particular to a pneumatic compression machine for container bag processing. Background Technology

[0002] FIBCs (Flexible Intermediate Bulk Containers) are bags used to package various goods, facilitating transportation and storage during production and distribution. They are widely used in daily life and industrial production, and the commercial nature of the packaging itself is becoming increasingly prominent. FIBCs have become a special product no longer dependent on commodity production, but a widely used product indispensable to all commodities. In terms of manufacturing process, they are often classified as plastic FIBCs and composite FIBCs. In terms of raw materials, they are classified as high-pressure polyethylene (HPE) plastic bags, low-pressure polyethylene (LPPE) plastic bags, polypropylene (PP) plastic bags, polyvinyl chloride (PVC) plastic bags, etc. During the processing of FIBCs, they are often compressed using a compression machine to facilitate transportation.

[0003] When compressing FIBCs, in order to prevent residual air from accumulating locally inside the bag and causing local rupture during the compression process, devices such as compression rollers are usually used to expel some of the air from the bag before compression. Although this method reduces the risk of FIBC rupture to some extent, it ignores the fact that manual operation is often required in the pretreatment process, which increases the number of steps in equipment operation and thus reduces the overall work efficiency.

[0004] Therefore, a pneumatic compression machine for processing bulk bags is proposed. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The pneumatic compression machine for processing bulk bags, through the setting of rotating rod, transmission gear, first toothed plate, mounting plate and second toothed plate, enables the device to compress bulk bags. As the compression plate descends, the pressing roller will automatically move forward to squeeze out some of the air in the bulk bag, thereby reducing the working steps of the device and improving the compression effect of the device.

[0015] (2) The pneumatic compression machine for processing bulk bags, by installing a vertical plate, a first connecting block, a buffer spring and a buffer plate, enables the compression roller to move longitudinally according to the thickness of the bulk bag when it is squeezing the bulk bag. While adapting to bulk bags of various thicknesses, it increases the squeezing force of the compression roller on the bulk bag, and thus can better compress the bulk bag. Attached Figure Description

Detailed Implementation

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a pneumatic compression machine for processing bulk bags, including a base plate 1, a mounting frame 2 fixedly installed on the top of the base plate 1, a support frame 3 fixedly installed on the bottom of the base plate 1, two sets of limiting plates 5 fixedly installed on the top of the base plate 1 and distributed left and right, with a bulk bag 6 arranged between the two sets of limiting plates 5, and a transmission mechanism 8 arranged inside the support frame 3. The transmission mechanism 8 includes a rotating rod 801 rotatably installed inside the support frame 3, and also includes a transmission gear 802, a first toothed plate 803, a mounting plate 804 and a second toothed plate 805, so that when the device compresses the bulk bag 6, as the compression plate 12 descends, the pressing roller 14 automatically moves forward to squeeze out some of the air in the bulk bag 6, thereby reducing the working steps of the device and improving the compression effect of the device.

[0024] like Figure 1 and Figure 3As shown, a mounting vertical plate 16 is fixedly mounted on the top of the mounting plate 804. A first through groove is provided on the bottom plate 1. The top of the mounting vertical plate 16 extends to the top of the bottom plate 1 through the first through groove. A mounting rod 13 is provided between the mounting vertical plates 16. A crushing roller 14 is rotatably mounted on the mounting rod 13. The crushing roller 14 has multiple sets of exhaust holes 15 arranged in a ring. A second sliding groove is provided on the mounting vertical plate 16. A second slider is slidably mounted inside the second sliding groove. One side of the second slider is fixedly connected to the mounting rod 13. A second connecting block 17 is fixedly mounted on the other side of the second slider. A buffer plate 19 is fixedly mounted on one side of the mounting vertical plate 16. A buffer spring 18 is fixedly mounted between the second connecting block 17 and the buffer plate 19. This allows the crushing roller 14 to move longitudinally according to the thickness of the container bag 6 when it is squeezing the container bag 6. This allows it to adapt to container bags 6 of various thicknesses while increasing the squeezing force of the crushing roller 14 on the container bag 6, thus enabling better compression of the container bag 6.

[0025] like Figure 1 As shown, a hydraulic rod 9 is fixedly installed on the top of the mounting frame 2. The free end of the hydraulic rod 9 extends into the interior of the mounting frame 2 and is fixedly installed with a pressing plate 12. A first connecting block 10 is fixedly installed on the free end of the hydraulic rod 9. A connecting rod 11 is fixedly installed on the rear side of the first connecting block 10. A guide frame 20 is fixedly installed on the rear inner wall of the mounting frame 2. A second through groove is provided on the guide frame 20. One end of the connecting rod 11 extends to the outside of the mounting frame 2 through the second through groove and is fixedly connected to the first toothed plate 803. By controlling the hydraulic rod 9 to start, the pressing plate 12 is driven to move longitudinally, thereby enabling the device to pneumatically press the container bag 6, improving the practicality of the device.

[0026] like Figure 1 As shown, two sets of support rods 7 are fixedly installed between the mounting frame 2 and the base plate 1. A placement plate 4 is fixedly installed inside the support frame 3. The placement plate 4 allows workers to place some of the tools and materials related to the processing of bulk bags on the placement plate 4, which facilitates the processing of bulk bags and indirectly improves the processing effect and practicality of the device.

[0027] Working principle: In use, the container bag 6 is placed between the limiting plates 5. The hydraulic rod 9 is activated, which drives the pressing plate 12 to press down. The first connecting block 10, connecting rod 11 and guide frame 20 enable the pressing plate 12 to drive the first toothed plate 803 to descend. The transmission gear 802 and the second toothed plate 805 enable the first toothed plate 803 to drive the mounting plate 804 to move laterally. This allows the crushing roller 14 to squeeze the container bag 6, squeezing out the air inside the container bag 6. The air can be better discharged through the exhaust hole 15. The second connecting block 17, buffer spring 18 and buffer plate 19 enable the crushing roller 14 to move longitudinally to a certain extent, thereby adapting to different thicknesses of the container bag 6 and applying stronger squeezing force to the container bag 6. After the crushing roller 14 has squeezed the container bag 6 to a certain extent, the pressing plate 12 can descend to the surface of the container bag 6 and press the container bag 6. After the pressing plate 12 has finished pressing, the hydraulic rod 9 is controlled to lift the pressing plate 12 and drive the crushing roller 14 to reset, and can squeeze the container bag 6 again.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
