[0036] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0037] like Figure 1 , Figure 2 As shown, at least one embodiment provides a ton bag integrated bag opening station, including: a mounting frame 1; a feeding bin 2, disposed on the mounting frame 1, with a standard bag feeding port 21 on the side of the feeding bin 2 and a ton bag feeding port 22 on the top of the feeding bin 2; a negative pressure filter mechanism 3, inserted into the feeding bin 2 and disposed near the standard bag feeding port 21; a tapping mechanism 4, disposed on the mounting frame 1 and located above the ton bag feeding port 22; and a control module electrically connected to the negative pressure filter mechanism 3 and the tapping mechanism 4, configured to control the negative pressure filter mechanism 3 to operate and create negative pressure in the feeding bin 2 to prevent dust from escaping when the standard bag feeding port 21 is in use, and further configured to control the tapping mechanism 4 to tap the ton bag when the ton bag feeding port 22 is in use; wherein, a bag clamping mechanism 5 for clamping the ton bag outlet is provided at the ton bag feeding port 22.
[0038] In this embodiment, by providing a standard bag feeding port 21 on the side and a ton bag feeding port 22 on the top of the feeding hopper 2, the feeding hopper 2 can accommodate material bags of both ton bags and standard bags. At the same time, by providing a negative pressure filtration mechanism 3, dust will not be generated when the standard bag feeding port 21 is in use. By providing a tapping mechanism 4, the ton bag feeding port 22 will help the material fall when in use. By providing a bag clamping mechanism 5, the ton bag feeding port 22 can clamp the ton bag outlet during feeding, thereby preventing dust from escaping.
[0039] like Figure 1 As shown, in some embodiments, a ton bag bracket 11 is provided on the top of the mounting frame 1; wherein the ton bag bracket 11 is located above the ton bag feeding port 22.
[0040] In this embodiment, after the ton bag is hoisted, it is placed on the ton bag bracket 11. At this time, the ton bag outlet extends through the ton bag bracket 11 to the ton bag feeding port 22.
[0041] like Figure 1 As shown, in some embodiments, a discharge pipe 23 is provided at the upper part of the feeding bin 2; wherein the discharge pipe 23 is located below the ton bag bracket 11; the upper end of the discharge pipe 23 is the ton bag feeding port 22.
[0042] like Figure 3 As shown, in some embodiments, the bag clamping mechanism 5 is disposed on the discharge pipe 23 and includes: a pair of lifting cylinders 51 symmetrically disposed on the side wall of the discharge pipe 23; a lower pressure ring 52 connected to the drive end of the two lifting cylinders 51 and coaxial with the discharge pipe 23; wherein, the control module is electrically connected to the two lifting cylinders 51 and is configured to control the two lifting cylinders 51 to descend synchronously to clamp the discharge port of the ton bag after the ton bag outlet is sleeved on the discharge pipe 23.
[0043] In this embodiment, the ton bag outlet passes through the lower pressure ring 52 and is fitted onto the upper end of the discharge pipe 23. Then, the lower pressure ring 52 is lowered by the lifting cylinder 51 to press the ton bag outlet tightly, so that dust will not escape when the ton bag outlet is opened for feeding.
[0044] In some embodiments, the inner diameter of the pressure ring 52 is the same as the inner diameter of the discharge pipe 23, thereby facilitating the material to fall.
[0045] like Figure 4 As shown, in some embodiments, the lower surface of the pressure ring 52 is provided with an annular mounting groove 521; an elastic sealing ring 522 is provided in the annular mounting groove 521; wherein, the elastic sealing ring 522 protrudes from the annular mounting groove 521.
[0046] In this embodiment, the compressed elastic sealing ring 522 prevents gaps from forming at the outlet of the compressed ton bag.
[0047] like Figure 3 As shown, in some embodiments, the striking mechanism 4 includes at least two lifting cylinders 41; wherein each lifting cylinder 41 is mounted on the mounting frame 1 and surrounds the discharge pipe 23; and the driving end of the lifting cylinder 41 is provided with an arc-shaped push block 42.
[0048] In this embodiment, the control module may be, but is not limited to, using a PLC; when the material has poor flowability, the control module controls the lifting cylinder 41 to push forward intermittently, thereby patting the material to help it fall.
[0049] like Figure 1 As shown, in some embodiments, the negative pressure filtration mechanism 3 includes: a housing 31, which is disposed on the feeding bin 2 and communicates with the feeding bin 2; a filter element 32, which is disposed inside the housing 31 and extends into the feeding bin 2 at one end; and an air pipe 33, one end of which is communicated with the housing 31 and the other end of which is used to connect to a negative pressure source.
[0050] In this embodiment, when the negative pressure source is working, the escaping dust will be drawn towards the filter element 32 and thus adhere to the filter element 32.
[0051] like Figure 3 As shown, in some embodiments, a pulse jet assembly 6 is connected to the air tube 33; wherein the pulse jet assembly 6 includes an air bag 61 and a pulse valve; the air bag 61 is connected to the air tube 33 through a conduit; the pulse valve is located at the air outlet of the air bag 61.
[0052] In this embodiment, after the filter element 32 has been used for a certain period of time, a large amount of dust will be attached to it, which will greatly reduce the adsorption effect. At this time, the negative pressure source is turned off, and air is blown in the opposite direction through the air bag 61 and the blowing frequency is controlled by the pulse valve, so that the filter element 32 receives air from the inside out, thereby causing the dust attached to the filter element 32 to fall off.
[0053] like Figure 1 As shown, in some embodiments, a label bag placement position is provided in the feeding bin 2, and a plurality of support rods 211 are provided in the label bag placement position; wherein each support rod 211 is equidistant.
[0054] In this embodiment, each support rod 211 forms a label bag placement position. When the label bag is placed on the support rod 211, the label bag is cut open by a knife, allowing the material to fall.
[0055] In summary, this integrated ton bag opening station allows the feeding bin 2 to accommodate both ton bags and label bags by setting a label bag feeding port 21 on the side and a ton bag feeding port 22 on the top. Simultaneously, a negative pressure filtration mechanism 3 prevents dust from escaping during the use of the label bag feeding port 21, a tapping mechanism 4 helps the material fall through the ton bag feeding port 22, and a bag clamping mechanism 5 prevents dust from escaping during ton bag feeding.
