[0033] Embodiment 1

[0034] Refer to Figure 1 、 Figure 2 、 Figure 10 A closed powder bag-breaking feeding device of the present invention includes a material conveying cylinder assembly 1 and a bag-breaking cylinder assembly 2,

[0035] The material conveying cylinder assembly 1 is provided with a material conveying cylinder body 11. A clamping and sealing cover 12 is hinged to the top of the material conveying cylinder body 11. The clamping and sealing cover 12 is composed of two semi-circular cover bodies. The arc edges of the two semi-circular cover bodies are hinged to both sides of the material conveying cylinder body 11. Anti-slip sealing strips 13 are provided on the opening and closing sides (straight edges) of the two semi-circular cover bodies. The anti-slip sealing strips 13 can be bonded to the end faces of the two semi-circular cover bodies. An upper breather 14 is provided on the clamping and sealing cover 12. A number of support rods 15 are arranged radially along the bottom of the inner wall of the material conveying cylinder body 11. A sealing ring 16 is provided on the outer wall of the material conveying cylinder body 11.

[0036] See Figure 2 , Figures 9 to 11 , open the clamping and sealing cover 12 upward. The two semi-circular cover bodies flip outward. The powder material bag 4 is loaded into the material conveying cylinder body 11 from above. The powder material bag 4 is seated on a number of support rods 15. The support rods 15 extend radially from the inner wall of the material conveying cylinder body 11 towards the center, forming an angle with each other and the ends not intersecting, leaving a moving space for the bag-breaking cone. When the clamping and sealing cover 12 is closed, the sealing edge of the powder material bag 4 is clamped to realize the stretching posture of the powder material bag 4. The anti-slip sealing strip 13 is in direct contact with the powder material bag 4, which not only plays a role in clamping the powder material bag 4 but also plays a role in sealing the material conveying cylinder body 11. A breathing port 17 is provided on the clamping and sealing cover 12, and the upper breather 14 is fixedly installed on the breathing port 17 by screws. Sealing rings 18 are provided between the clamping and sealing cover 12, the upper breather 14 and the material conveying cylinder body 11.

[0037] See Figure 3 , Figure 4 , Figure 12 , the bag-breaking cylinder assembly 2 is provided with a bag-breaking cylinder body 21. A shaft seat 22 is provided at the center of the bag-breaking cylinder body 21. The shaft seat 22 is connected to the inner wall of the bag-breaking cylinder body 21 through a number of spokes 23. A bag-breaking cone 24 is provided on the shaft seat 22. The bag-breaking cone 24 is provided with a cone rod 241. A number of cutting knives 242 are arranged radially on the upper part of the cone rod 241. A retaining ring 243 is provided on the lower part of the cone rod 241. The cone rod 241 is installed on the shaft seat 22 through the retaining ring 243 and a shaft retaining ring 244. A lower breather 25 is provided on the outer wall of the bag-breaking cylinder body 21.

[0038] A vertical shaft hole is provided on the shaft seat 22. The lower end of the cone rod 241 is inserted into the shaft hole. The retaining ring 243 abuts against the upper end of the shaft hole. A retaining ring groove is provided at the lower end of the cone rod 241 extending out of the shaft hole, and the shaft retaining ring 244 is installed in the retaining ring groove to restrict the axial movement of the bag-breaking cone 24.

[0039] See Figure 12, the head end of the conical rod 241 of the bag-breaking cone 24 is conical, which is convenient for piercing a hole in the powder material bag 4 and laying a foundation for the subsequent bag-breaking by the cutter 242. The cutter 242 gradually widens from top to bottom along the conical surface of the head end and contracts inward in the middle and lower parts. On the one hand, it avoids interfering with the inner wall of the material conveying cylinder body, and on the other hand, it is convenient for inserting into and withdrawing from the hole of the powder material bag 4. The number of cutters 242 can be set as required, but not too many to avoid occupying too much space for material discharging.

[0040] See Figure 5 , Figure 6 , the bottom of the material conveying cylinder body 11 is inserted into the bag-breaking cylinder body 21, and the material conveying cylinder body 11 is hermetically connected to the bag-breaking cylinder body 21 through a sealing ring 16. The bottom of the bag-breaking cylinder body 21 is hermetically connected to the receiving device 3, and the material conveying cylinder body 11, the bag-breaking cylinder body 21 and the receiving device 3 form a closed and breathable space.

[0041] See Figure 8 , in this embodiment, a self-locking mechanism is further provided on the opening and closing side of the two semi-circular cover bodies. The self-locking mechanism includes a support 121 and a self-locking crank 122. The self-locking crank 122 is rotatably installed on the support 121 through a hinge shaft. A locking block 123 is provided below the hinge shaft, and a fork-shaped clip 124 is provided at the lower end of the self-locking crank 122. The support 121 is fixed on one of the semi-circular cover bodies.

[0042] See Figure 7 , Figure 8 , two self-locking mechanisms are provided along the opening and closing side of the two semi-circular cover bodies. Rotate the self-locking crank 122 downward, the locking block 123 presses the upper end of the opening and closing side of the two semi-circular cover bodies, and the fork-shaped clip 124 clamps on the outside of the opening and closing side of the two semi-circular cover bodies to realize the locking of the clamping seal cover 12. Rotate the self-locking crank 122 upward, the locking block 123 disengages from the opening and closing side of the two semi-circular cover bodies, and the fork-shaped clip 124 moves out of the outside of the opening and closing side of the two semi-circular cover bodies to realize the unlocking of the clamping seal cover 12.

[0043] Before actual production operation, the feeding equipment 3 is first comprehensively debugged. After the debugging is completed, the clamping and sealing cover 12 is opened, and the powder material bag 4 is put into the material conveying cylinder body 11. When the material bag falls, the supporting rod 15 fixes the position of the powder material bag through physical block or friction force, preventing it from rotating or shifting synchronously with the bag-breaking cone 24, and ensuring that the bag-breaking cone 24 can accurately act on a specific area of the powder material bag. Then the clamping and sealing cover 12 is closed. The top edge of the powder material bag 4 is located between the two anti-slip sealing strips 13, and the clamping and sealing cover 12 is locked through the self-locking mechanism. The material conveying cylinder body 11 is lifted to directly above the bag-breaking cylinder body 21 by a manipulator or other lifting device, and the material conveying cylinder body 11 is slowly lowered, so that the material conveying cylinder body 11 is inserted into the bag-breaking cylinder body 21 until the lower end of the material conveying cylinder body 11 contacts the spoke 23 in the bag-breaking cylinder body 21. The bottom of the powder material bag 4 is punctured and cut open by the bag-breaking cone 24 located in the bag-breaking cylinder body 21, and the powder then pours down from the bottom of the bag and flows into the feeding equipment 3. During the cooperation process of the material conveying cylinder body 11 and the bag-breaking cylinder body 21, the gas in the closed cavity of the bag-breaking cylinder body 21 and the material conveying cylinder body 11 is discharged through the upper breather 14 on the clamping and sealing cover 12 and the lower breather 25 on the bag-breaking cylinder body 21, which is beneficial to the insertion of the material conveying cylinder body 11 into the bag-breaking cylinder body 21; when the powder flows into the feeding equipment 3, the gas overflowing in the feeding equipment 3 will be discharged through the lower breather 25 on the bag-breaking cylinder body 21, which is beneficial to the falling of the powder. The bag-breaking and feeding are carried out in a closed and breathable space, preventing dust from overflowing, providing a healthy working environment, reducing the feeding loss, and improving the feeding efficiency. After the powder in the powder material bag becomes less, there is still residue. After the bag-breaking and feeding, the material conveying cylinder body 11 can be lifted up and down or twisted left and right in the circumferential direction within a certain range, so that the bag-breaking cone 24 in the bag-breaking cylinder body 11 forms a mechanical impact on the material bag, or scrapes the material bag. The impact between the material conveying cylinder body 11 and the spoke 23 causes the material bag to vibrate, just like the action of shaking the material bag, so as to further empty the powder material bag.

[0044] See Figure 11 , in this embodiment, a pair of L-shaped support plates 111 are respectively arranged on both sides of the material conveying cylinder body 11. Two connecting plates 125 extend horizontally from the outer sides of the two semi-circular covers. The two connecting plates 125 of one semi-circular cover are hinged to a pair of L-shaped support plates 111 on one side of the material conveying cylinder body, and the two connecting plates 125 of the other semi-circular cover are hinged to a pair of L-shaped support plates 111 on the other side of the material conveying cylinder body. The L-shaped support plates 111 can improve the structural strength and better support the semi-circular cover.

[0045] See Figure 10, in this embodiment, a reinforcing ring 112 is provided on the outer wall of the material conveying cylinder 11. One end of the support rod 15 is fixedly welded to the inner wall of the material conveying cylinder 11, and the reinforcing ring 112 is arranged corresponding to the welding position. The support rod 15 is of a cantilever structure. The structural strength of the side wall of the material conveying cylinder 11 is improved through the reinforcing ring to prevent the welded part from deforming under stress.

[0046] See Figure 9 , in this embodiment, a handle 126 is provided on the clamping and sealing cover 12. The handle 126 facilitates the operation of opening and closing the clamping and sealing cover 12.

[0047] See Figure 3 , Figure 5 , in this embodiment, a polytetrafluoroethylene spacer 26 is provided between the retaining ring 243 and the shaft seat 22. The spacer 26 is equivalent to a solid bearing. The bag-breaking cone 24 can rotate relative to the shaft seat 22 through the spacer 26. When the position of the bag-breaking cone 24 interferes with that of the support rod 15, the bag-breaking cone 24 rotates by a certain angle to avoid interference, which can protect the cutting edge of the cutter 242 from impact. When the bag-breaking cone 24 rotates, its surface structure forms a relative movement with the support rod 15, and the material bag is clamped between the two and bears the following forces: Tear propagation: After the cutter 242 of the bag-breaking cone 24 is inserted into the material bag, the crack continuously expands as the material bag moves downward, forming a controllable bag-breaking path. Vibration assistance: Rotating the material conveying cylinder 11 can generate a vibration effect between the bag-breaking cone 24 and the support rod 15, thereby vibrating the material bag, loosening the material, reducing adhesion, and accelerating discharge.

[0048] See Figure 3 , in this embodiment, an upwardly inclined bypass pipe 27 is provided on the outer wall of the bag-breaking cylinder 21, and the lower respirator 25 is installed on the bypass pipe 27. The bypass pipe 27 is arranged to be upwardly inclined, which facilitates the smooth discharge of gas.

[0049] See Figure 3 , in this embodiment, a hanging ring 28 is provided on the outer wall of the bag-breaking cylinder 21. The bag-breaking cylinder 21 can be quickly and hermetically connected to and separated from the inlet of different receiving devices 3 through the hanging ring 28.

[0050] See Figure 3 , in this embodiment, the upper end of the bag-breaking cylinder 21 is a flared opening 29, and the lower end of the bag-breaking cylinder 21 is funnel-shaped. When the material conveying cylinder 11 enters the bag-breaking cylinder 21 downward, the flared opening 29 can play a guiding role. When the bag-breaking cylinder 21 is connected to the receiving device 3, the funnel shape can play a guiding role and at the same time block part of the dust.

[0051] In this embodiment, the sealing ring 16 is made of felt material, and the anti-slip sealing strip 13 is made of rubber material.

[0052] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
