[0043] Example 1

[0044] like Figures 1 to 4As shown, the high-sealing cylinder mechanism includes a hollow cylinder body 11, a bag-pressing assembly 12 for fixing ton bags, and an airbag assembly 13 fitted onto the cylinder body 11. The bag-pressing assembly 12 is fitted onto the cylinder body 11. The cylinder body 11 has a cylinder inlet 111 on its upper surface and a cylinder outlet 112 on its lower surface. The airbag assembly 13 includes an airbag body 131 and a hollow airbag shell 132. The airbag shell 132 is fitted onto the cylinder body 11 via an assembly step 113 on the outer circumferential surface of the cylinder body 11. The lower end face of the airbag shell 132 mates with the upper end face of the assembly step 113. The bag-pressing assembly 12 includes a pressure... The upper pressure plate 121, the lower pressure plate 122, and the pressure brackets 123 disposed on both sides of the material cylinder body 11 are provided. The outer end face of the upper pressure plate 121 is connected to the pressure bracket 123. The lower inner end face of the upper pressure plate 121 is engaged with the upper end face of the lower pressure plate 122. The lower end face of the lower pressure plate 122 is engaged with the upper end face of the airbag shell 132. The lower end face of the lower pressure plate 122, the inner circumferential surface of the airbag shell 132, the outer circumferential surface of the material cylinder body 11, and the upper end face of the assembly step 113 enclose and form an airbag receiving space for accommodating the airbag body 131. After the airbag body 131 is inflated, it is squeezed towards the lower end face of the lower pressure plate 122.

[0045] The working principle of Example 1 is as follows:

[0046] 1) Lift the upper pressure plate 121 of the bag to separate the upper pressure plate 121 and the lower pressure plate 122 of the bag, and place the ton bag into the separation gap between the upper pressure plate 121 and the lower pressure plate 122 of the bag; after the ton bag is placed, press the upper pressure plate 121 onto the lower pressure plate 122 of the bag, so that the ton bag is sandwiched between the upper pressure plate 121 and the lower pressure plate 122 of the bag;

[0047] 2) Inflate the cavity of the airbag body 131 with air, so that the airbag body 131 expands in the airbag containment space;

[0048] 3) After the airbag body 131 is inflated to a certain volume, it will be squeezed towards the lower end face of the pressure bag lower pressure plate 122, thereby applying an upward pressure to the pressure bag lower pressure plate 122, thus increasing the clamping force between the pressure bag upper pressure plate 121 and the pressure bag lower pressure plate 122.

[0049] The beneficial effects of Example 1 are as follows: By setting the airbag assembly 13, this example increases the clamping force between the upper pressure plate 121 and the lower pressure plate 122 of the bag, thereby improving the assembly compactness of the bag assembly 12. At the same time, it prevents dust materials from leaking between the upper pressure plate 121 and the lower pressure plate 122 of the bag, and improves the sealing performance of the material cylinder mechanism.

[0050] Preferably, the airbag body 131 includes an upper fixing part 1311, a lower fixing part 1312, and an expansion part 1313. The upper fixing part 1311 is fixed to the upper end face of the airbag shell 132, the lower fixing part 1312 is fixed to the lower end face of the airbag shell 132, and the expansion part 1313 corresponds to the inner circumferential surface of the airbag shell 132, forming a cavity within the airbag body 131 between the expansion part 1313 and the inner circumferential surface of the airbag shell 132. With the above arrangement, the airbag body 131 can be fixed inside the airbag shell 132 by the upper fixing part 1311 and the lower fixing part 1312.

[0051] Preferably, the outer peripheral surface of the airbag shell 132 is provided with an inflation port 1321 that communicates with the cavity of the airbag body 131. With the above arrangement, the airbag body 131 can be inflated from the outside into the cavity of the airbag body 131 through the inflation port 1321.

[0052] Preferably, the airbag assembly 13 further includes an upper airbag pressure plate 133 and a lower airbag pressure plate 134. The lower end face of the lower airbag pressure plate 122 engages with the upper end face of the airbag housing 132 via the upper airbag pressure plate 133. The lower end face of the airbag housing 132 engages with the upper end face of the assembly step 113 via the lower airbag pressure plate 134. An upper fixing part 1311 is fixed between the lower end face of the upper airbag pressure plate 133 and the upper end face of the airbag housing 132, and a lower fixing part 1312 is fixed between the upper end face of the lower airbag pressure plate 134 and the lower end face of the airbag housing 132. This configuration improves the assembly stability of the airbag body 131 and the airbag housing 132, preventing the airbag body 131 from detaching.

[0053] Preferably, a dust collection component 14 is fitted at the material cylinder inlet 111. The dust collection component 14 has a dust collection channel 141 inside, a dust collection hole 142 communicating with the dust collection channel 141 on its inner circumferential surface, and a dust collection port 143 communicating with the dust collection channel 141 on its outer circumferential surface. The dust collection port 143 is connected to an external air extraction device. The lower end face of the dust collection component 14 mates with the upper end face of the pressure plate 121 on the pressure bag. Through the above arrangement, the dust collection component 14 can absorb the dust floating at the material cylinder inlet 111, thereby avoiding the waste of dusty materials; and the distance between the dust collection component 14 and the material cylinder inlet 111 is close, resulting in good dust collection effect.

[0054] Preferably, the bag-pressing assembly 12 further includes a lifting device 124 disposed on the bag-pressing bracket 123. The outer end face of the upper pressing plate 121 is connected to the bag-pressing bracket 123 through the lifting device 124. The lifting end of the lifting device 124 is drively connected to the upper pressing plate 121. The lifting device 124 is a hydraulic cylinder or a pneumatic cylinder. With the above arrangement, the lifting device 124 can lift the upper pressing plate 121, thereby separating the upper pressing plate 121 from the lower pressing plate 122, which is beneficial for the automated setting of the material cylinder mechanism.

[0055] Preferably, a feed top cover 15 is detachably installed at the feed inlet 111 of the material cylinder. With the above arrangement, when the material cylinder mechanism is not working, the feed top cover 15 can be placed on the feed inlet 111 of the material cylinder to prevent external dust and impurities from entering the inside of the material cylinder mechanism and contaminating the powder material.

[0056] Example 2

[0057] like Figure 5 As shown, the feeding device includes a frame 2; it also includes a high-sealing material cylinder mechanism 1 as described in any of Embodiment 1, the high-sealing material cylinder mechanism 1 being mounted on the frame 2.

[0058] The beneficial effects of Example 2 are as follows: By setting an airbag assembly 13 on the high-sealing material cylinder mechanism 1, this example increases the clamping force between the upper pressure plate 121 and the lower pressure plate 122 of the bag pressing, thereby improving the assembly compactness of the bag pressing assembly 12. At the same time, it prevents dust materials from leaking between the upper pressure plate 121 and the lower pressure plate 122 of the bag pressing, thus improving the sealing performance of the feeding equipment.

[0059] Preferably, the system further includes a screen mechanism 3 and an iron removal mechanism 5, which are mounted on the frame 2 and sequentially positioned below the high-sealing material cylinder mechanism 1. Through this arrangement, dusty materials sequentially pass through the high-sealing material cylinder mechanism 1, the screen mechanism 3, and the iron removal mechanism 5; the screen mechanism 3 is used to screen and filter the dusty materials, and the iron removal mechanism 5 is used to remove iron from the dusty materials.

[0060] Preferably, the system further includes a vibrating chamber mechanism 4 mounted on the frame 2. The vibrating chamber mechanism 4 is positioned between the screen mechanism 3 and the iron removal mechanism 5, and the screen mechanism 3 is mounted on the frame 2 via the vibrating chamber mechanism 4. With this configuration, the vibrating chamber mechanism 4 can drive the screen mechanism 3 to vibrate together, facilitating the easier and faster passage of dusty materials through the screen mechanism 3.

Therefore, the present invention is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
