[0034] See also Figure 1-Figure 8A cement conveying and packaging device comprises a filling component 1, a conveyor belt 2 and a sealing component 3. The filling component 1 comprises a filling bucket 101. The bottom end of the filling bucket 101 is connected to a No. 1 butterfly valve 102 through a flange. The bottom end of the No. 1 butterfly valve 102 is fixedly connected to a feed pipe 103. The No. 1 butterfly valve 102 is bolted to a weighing sensor 104. The bottom end of the weighing sensor 104 is bolted to a quantitative cylinder 105. The bottom end of the quantitative cylinder 105 is flanged to a No. 2 butterfly valve 106. The bottom end of the No. 2 butterfly valve 106 is fixedly connected to a cannula 107.

[0035] The sealing assembly 3 includes two support rods 301, the top of the support rod 301 is fixedly connected to an ultrasonic generator 302, the back of the ultrasonic generator 302 is installed with a fixing plate 303, the outer surface of the fixing plate 303 is connected to a cover 304 by bolts, a transducer 305 is installed inside the cover 304, the bottom end of the transducer 305 is connected to an amplitude change rod 306 by a flange, the bottom end of the amplitude change rod 306 is fixedly connected to an adapter 307, the inner side of the adapter 307 is rotatably connected to a welding head 308, the outer surfaces of the cover 304 and the fixing plate 303 are fixedly connected to a C-shaped frame 309, the inner side of the C-shaped frame 309 is rotatably connected to a plurality of pulleys 310 and an auxiliary wheel 311, the plurality of pulleys 310 are transmission-connected with a synchronous belt 312, and a servo motor 313 is installed on the top of the C-shaped frame 309.

[0036] Furthermore, the outer surface of the filling bucket 101 is fixedly connected to the support frame 4, and a square shell 5 is welded to the bottom of the filling bucket 101, and the two sides of the square shell 5 are rotatably connected to the first connecting plate 6 and the second connecting plate 7, one end of the first connecting plate 6 is fixedly connected to the first clamping plate 8, and one end of the second connecting plate 7 is fixedly connected to the second clamping plate 9. The advantage is that the bag mouth of the cement packaging bag is manually put on the outer surface of the insertion tube 107, and then the output end of the cylinder 10 is extended by starting the cylinder 10 to drive the first connecting plate 6 to rotate around the pin connected to the square shell 5, so that the first connecting plate 6 can drive the first clamping plate 8 to approach the insertion tube 107, and the first connecting plate 6 will pull the connecting rod 11, and the connecting rod 11 will pull the second connecting plate 7 to rotate around the pin connected to the square shell 5, so that the second connecting plate 7 also drives the second clamping plate 9 to approach the insertion tube 107, and finally the first clamping plate 8 cooperates with the second clamping plate 9 to firmly clamp the bag mouth of the packaging bag.

[0037] Furthermore, the outer surface of the No. 1 connecting plate 6 is rotatably connected to the cylinder 10, and the cylinder end of the cylinder 10 is rotatably connected to the two sides of the square shell 5, and the No. 1 connecting plate 6 and the No. 2 connecting plate 7 are rotatably connected to the connecting rod 11. The advantage is that cement is loaded into the filling bucket 101, and the entire filling assembly 1 is supported by the support frame 4. When the No. 1 butterfly valve 102 is opened, the cement in the filling bucket 101 will automatically fall, and the cement will enter the quantitative cylinder 105 through the feeding pipe 103 for storage. At this time, the weighing sensor 104 measures the cement in the quantitative cylinder 105. When the threshold value set by the weighing sensor 104 is reached, the No. 1 butterfly valve 102 is immediately closed, and the material is no longer discharged from the filling bucket 101. The measured cement is temporarily stored in the quantitative cylinder 105. At this time, the No. 2 butterfly valve 106 is opened to make the cement in the quantitative cylinder 105 fall through the insertion tube 107. It is only necessary to put the bag mouth of the packaging bag on the insertion tube 107 to achieve quantitative filling of cement.

[0038] Furthermore, the conveyor belt 2 includes a vertical plate 201 mounted on the frame, and the outer surface of the vertical plate 201 is fixedly connected to a limit rod 202. The advantage is that after the cement filling in the packaging bag is completed, the cement can be transported through the conveyor belt 2, and the cement packaging bag can be limited by setting two sets of limit rods 202 to keep it standing and prevent it from tipping to the sides of the conveyor belt 2.

[0039] Furthermore, four weighing sensors 104 are arranged circumferentially around the axis direction of the feeding tube 103, and the feeding tube 103 is inserted into the inside of the quantitative cylinder 105, and the outer wall of the feeding tube 103 does not contact the inner wall of the quantitative cylinder 105. The advantage is that by arranging four weighing sensors 104 circumferentially around the axis direction of the feeding tube 103, the weighing can be monitored from multiple angles, ensuring that the measurement of the weight of the cement in the quantitative cylinder 105 is more accurate and stable, the outer wall of the feeding tube 103 does not contact the inner wall of the quantitative cylinder 105, and the friction or collision between the feeding tube 103 and the quantitative cylinder 105 during the feeding process can be avoided to interfere with the measurement of the weighing sensor 104, further improving the measurement accuracy, the feeding tube 103 is inserted into the inside of the quantitative cylinder 105 and does not contact the inner wall, providing a relatively independent channel for the feeding of cement, so that the cement can flow more smoothly from the feeding tube 103 into the quantitative cylinder 105, reducing the risk of blockage during the feeding process, and ensuring the high efficiency of the feeding.

[0040] Furthermore, a sealing ring 12 is sleeved on the outer wall of the feed pipe 103, and the top of the metering cylinder 105 abuts against the sealing ring 12. The advantage is that, since cement will go through a process from high to low when falling from the feed pipe 103 into the metering cylinder 105, dust will appear. By providing the sealing ring 12 and the top of the metering cylinder 105 abutting against the sealing ring 12, dust leakage can be effectively prevented.

[0041] Furthermore, a PLC control box 13 is installed on the outer surface of the support frame 4, and both the No. 1 butterfly valve 102 and the No. 2 butterfly valve 106 are electric butterfly valves. The advantage is that the PLC control box 13 can accurately receive the signal of the weighing sensor 104, realize high-precision measurement of the weight of cement, and can accurately determine when the set weight threshold is reached, so as to timely control the opening and closing of the No. 1 butterfly valve 102, ensure that the filling amount of each bag of cement is accurate and consistent, and control the No. 1 butterfly valve 102 and the No. 2 butterfly valve 106 more accurately, and can realize fast and accurate opening and closing actions, avoiding the problem of too much or too little material discharge due to inaccurate control.

[0042] Furthermore, the output shaft of the servo motor 313 is connected to a pulley 310, and the two C-shaped frames 309 are internally rotatably connected with a plurality of pulleys 310 arranged at equal intervals. The advantage is that by starting the servo motor 313, one of the pulleys 310 can be driven to rotate, and since the other pulleys 310 are all connected through the synchronous belt 312, the plurality of pulleys 310 can rotate synchronously, and the synchronous belt 312 can rotate cyclically, so that when the bag opening of the packaging bag enters between the two synchronous belts 312, the synchronous belt 312 can squeeze the bag opening, so that the bag opening remains flat, thus preparing for the subsequent sealing.

[0043] Furthermore, the auxiliary wheel 311 is in rolling contact with the synchronous belt 312, and there is a 5 mm gap between the two C-shaped frames 309. The advantage is that by providing an auxiliary wheel 311 between the two pulleys 310 to change the angle at which the synchronous belt 312 wraps around the pulley 310, the pulley 310 and the synchronous belt 312 are in full contact, so that the pulley 310 can rotate with the synchronous belt 312.

[0044] Furthermore, the ultrasonic generator 302 is connected to the transducer 305 via a cable, and a groove is provided on the outer surface of the welding head 308. When the opening of the cement bag is rolled and contacted by the welding head 308 under the guidance of the synchronous belt 312, a high-frequency electrical signal of 20kHz to 40kHz is generated by the ultrasonic generator 302, and then the transducer 305 receives the high-frequency electrical signal from the ultrasonic generator 302 and converts it into a high-frequency mechanical vibration. The synchronous horn 306 amplifies the amplitude of the mechanical vibration generated by the transducer 305, and the adapter 307 serves to connect the horn 306 and the welding head 308, and it smoothly transmits the mechanical vibration from the horn 306 to the welding head. 308. When the bag opening contacts the welding head 308, the welding head 308 acts on the sealing part of the packaging bag with high-frequency vibration. The molecules on the surface of the two layers of plastic materials at the bag opening rub against each other under the high-frequency vibration of the welding head 308, generating local high temperature. This high temperature causes the plastic material to melt rapidly. Under the continuous action of pressure, the molten plastic material fuses together to achieve the purpose of sealing. The overall structure can perform sealing operations immediately after cement filling, avoiding subsequent sealing, and can transport cement through the conveyor belt 2. The overall structure improves the efficiency of cement processing.

[0045] When in use, first manually pick up the cement packaging bag and put its bag mouth on the insertion tube 107, then start the cylinder 10 to extend its output end to drive the No. 1 connecting plate 6 to rotate around the pin connected to the square shell 5, so that the No. 1 connecting plate 6 can drive the first clamping plate 8 to approach the insertion tube 107, and the No. 1 connecting plate 6 will pull the connecting rod 11, and the connecting rod 11 will pull the No. 2 connecting plate 7 to rotate around the pin connected to the square shell 5, so that the No. 2 connecting plate 7 also drives the second clamping plate 9 to approach the insertion tube 107, and finally the first clamping plate 8 cooperates with the second clamping plate 9 to firmly clamp the bag mouth of the packaging bag; then the PLC The control box 13 controls the No. 1 butterfly valve 102 to open, so that the cement in the filling bucket 101 will fall into the inside of the quantitative cylinder 105 through the discharge pipe 103, and the cement will be measured by the weighing sensor 104. When the set weight threshold is reached, the weighing sensor 104 sends a signal to the PLC control box 13, and the PLC control box 13 closes the No. 1 butterfly valve 102 to stop the discharge, and then immediately opens the No. 2 butterfly valve 106, so that the cement in the quantitative cylinder 105 will be automatically transported to the inside of the packaging bag through the cannula 107, and then the No. 2 butterfly valve 106 is closed again, and the cylinder 10 is reset to make the first clamping plate 8 The second clamping plate 9 releases the bag opening, so that the packaging bag and the cement inside it automatically fall onto the conveyor belt 2. Since two limit rods 202 are set to limit the packaging bag, it is prevented from tipping over to the two sides of the conveyor belt 2. The cement packaging bag is moved to the vicinity of the sealing component 3 through the conveyor belt 2, and the bag opening is manually guided to enter between the two synchronous belts 312. By starting the servo motor 313, one of the pulleys 310 can be driven to rotate. Since the other pulleys 310 are connected by the synchronous belt 312, several pulleys 310 can rotate synchronously, and the synchronous belt 312 can rotate cyclically. In this way, when the bag opening of the packaging bag enters When between the two synchronous belts 312, the synchronous belt 312 can squeeze the bag opening so that the bag opening remains flat, and finally the sealing part of the packaging bag is contacted by the welding head 308, and at the same time the welding head 308 can be driven to rotate by one of the pulleys 310. Since the ultrasonic generator 302 is set to generate a high-frequency electrical signal, which is transmitted to the transducer 305 and converted into mechanical vibration, the vibration amplitude is increased by the amplitude rod 306, and then the high-frequency vibration is transmitted to the welding head 308 through the adapter 307, so that the welding head 308 can seal the cement packaging bag, and finally the sealed cement is transported away by the conveyor belt 2 to complete the entire packaging and transportation process.
