Technical Field

[0001] This utility model belongs to the field of cement bag opening technology, and in particular relates to a rotary cutting type cement bag opening machine. Background Technology

[0002] Cement is a powdered hydraulic inorganic binder that forms a paste when mixed with water. It hardens in air or water and can firmly bind materials such as sand and stone together. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, national defense and other projects.

[0003] The conventional method of unpacking cement bags is mainly done manually. People use a knife to cut open the bag opening or remove the seal, and then pour the cement into the storage tank. This operation is not only labor-intensive but also unsafe. In addition, the cement dust generated by manually dumping cement will fly everywhere, increasing the dust content in the air and affecting the respiratory health of workers, posing a certain safety hazard.

[0004] Therefore, it is necessary to provide a new rotary cutting type bag-opening machine for cement to solve the above-mentioned technical problems. Utility Model Content

[0022] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A first three-dimensional structural schematic diagram of the rotary cutting type bag-opening machine for cement provided by this utility model; Figure 2 A second three-dimensional structural schematic diagram of the rotary cutting type bag-opening cement machine provided by this utility model; Figure 3 This is a third perspective structural diagram of the rotary-cutting bagged cement unpacking machine provided by this utility model. The rotary-cutting bagged cement unpacking machine includes: a support plate 1, on which a hollow groove is formed; four support rods 101 are fixedly installed at the bottom of the support plate 1, and the four support rods 101 are distributed in a rectangular array along the bottom of the support plate 1; a rotary cutting mechanism, a conveying mechanism, and a material receiving mechanism are provided on the support plate 1.

[0023] The rotary cutting mechanism includes a feeding bin 2, which is fixedly installed in a hollow groove. A rotating rod 201 is rotatably installed in the feeding bin 2. A rotary cutting blade 202 is fixedly sleeved on the rotating rod 201. A transmission wheel 203 is fixedly connected to one end of the rotating rod 201 that extends outside the feeding bin 2.

[0024] The conveying mechanism includes four fixed frames 3, which are fixedly installed on the support plate 1. A rotating rod 301 is rotatably installed between two of the fixed frames 3. Two gears 302 are fixedly sleeved on the rotating rod 301. A rack conveyor belt 303 is wound between the two gears 302. A plurality of positioning pins 304 are fixedly installed on the rack conveyor belt 303. The plurality of positioning pins 304 are equidistantly distributed along the outside of the rack conveyor belt 303. A transmission wheel 305 is fixedly connected to one end of the corresponding rotating rod 301.

[0025] The receiving mechanism includes a receiving bin 4, which is fixedly installed at the bottom of the feeding bin 2. A conveying auger 401 is rotatably installed inside the receiving bin 4, and a conical wheel 402 is fixedly connected to one end of the conveying auger 401 that extends outside the receiving bin 4.

[0026] like Figure 3 As shown, a mounting bracket 5 is fixedly installed on the support plate 1, a motor 501 is fixedly installed on the mounting bracket 5, two connecting rods 502 are fixedly installed on the support plate 1, and a rotating rod 503 is rotatably installed between the two connecting rods 502. One end of the rotating rod 503 is fixedly connected to the output shaft of the motor 501. A conical wheel 504 is fixedly sleeved on the rotating rod 503. The conical wheel 504 meshes with a conical wheel 402. A transmission wheel 505 is fixedly connected to one end of the rotating rod 503. A transmission belt 506 is wound between the transmission wheel 505, the transmission wheel 205, and the transmission wheel 203.

[0027] The mounting bracket 5 is powered on, which drives the rotating rod 3 503 to rotate. The rotating rod 3 503 then drives the conical wheel 2 504 to rotate. The conical wheel 1 402, which meshes with the conical wheel 2 504, will be driven to rotate. Then, the rotating rod 3 503 simultaneously drives the transmission wheel 3 505 to rotate, so that the transmission wheel 3 505 drives the transmission wheel 1 203 to rotate through the transmission belt 506. Then, the transmission wheel 1 203 drives the transmission wheel 2 305 to rotate through the transmission belt 506, thereby achieving the transmission and linkage of kinetic energy.

[0028] like Figure 1 As shown, a dust cover 6 is fixedly installed on the support plate 1. Dust baffles 601 are provided on both sides of the dust cover 6. The top of the dust baffles 601 is rotatably hinged to the dust cover 6. The top of the feeding bin 2 is located inside the dust cover 6.

[0029] By providing a dust cover 6, the processes of cutting the cement bag and pouring the cement out of the bag can be completed inside the dust cover 6, thereby preventing cement dust from spreading into the air.

[0030] like Figure 1As shown, four buffer pads 7 are fixedly installed on the dust cover 6, and one side of the dust baffle 601 abuts against the buffer pads 7.

[0031] By setting a buffer pad 7, after the cement bag pushes the dust baffle 601 open and completely enters the dust cover 6, the dust baffle 601 can be pushed against the buffer pad 7 when it resets and rotates, which makes it easy for the dust baffle 601 to quickly position and block the port of the dust cover 6, reducing the amount of dust that can be diffused.

[0032] like Figure 1 As shown, the dustproof baffle 601 has a slot, which is adapted to the positioning pin 304;

[0033] By providing slots in the dustproof baffle 601, the dustproof baffle 601 will not block the movement of the positioning pin 304 when the rack and pin conveyor belt 303 drives the positioning pin 304 to move.

[0034] like Figure 2 As shown, the inner cavity of the feeding bin 2 is configured with an inclined structure, and the feeding bin 2 is connected to the receiving bin 4;

[0035] The inclined structure of the inner cavity of the feeding hopper 2 is designed to facilitate the rapid flow of cement from the inclined surface into the receiving hopper 4, where the cement is then collected and discharged.

[0036] The working principle of the rotary cutting type bag-opening machine for cement provided by this utility model is as follows:

[0037] First step: By placing the cement bag on two rack conveyor belts 303, and then inserting the positioning pins 304 on the rack conveyor belts 303 into both ends of the cement bag, the cement bag is positioned. Then, the mounting frame 5 is powered on and drives the rotating rod 3 503 to rotate. Then, the rotating rod 3 503 drives the conical wheel 2 504 to rotate. Then, the rotating rod 3 503 drives the transmission wheel 3 505 to rotate, so that the transmission wheel 3 505 drives the transmission wheel 1 203 to rotate through the transmission belt 506. Then, the transmission wheel 1 203 drives the transmission wheel 2 305 to rotate through the transmission belt 506.

[0038] The second step: After the transmission wheel 2 305 is driven to rotate, it can drive the rotating rod 2 301 to rotate. Then the rotating rod 2 301 drives the gear 302 to rotate, so that the gear 302 drives the rack and pinion conveyor belt 303 to move. After that, the cement bag fixed on the rack and pinion conveyor belt 303 pushes open the dust baffle 601 and enters the dust cover 6. Then, after the cement bag approaches the rotary cutting blade 202, the transmission wheel 1 203 driven to rotate will drive the rotating rod 1 201 to rotate. Then the rotating rod 1 201 drives the rotary cutting blade 202 to rotate, so that the rotary cutting blade 202 can cut the middle part of the cement bag. Then the cement flows out of the bag and falls into the feeding hopper 2.

[0039] The third step: The cement that falls into the feeding bin 2 will enter the receiving bin 4. Then, the conical wheel 1 402 will rotate through the second conical wheel 504. The first conical wheel 402 will then drive the conveying auger 401 to rotate, so that the conveying auger 401 can push the cement to the port of the receiving bin 4 for collection. When the cement in the bag is empty, the empty cement bag will be moved out from the other side port of the dust baffle 601 and will be conveyed to the bottom of the positioning nail 304, so that the empty cement bag will fall automatically.
