Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement processing technology, specifically to a cement packaging machine. Background Technology
[0002] Cement is a powdered hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or water and can firmly bind materials such as sand and stone together. After the cement is processed, it needs to be bagged and packaged.
[0003] When using existing cement packaging machines, it is generally necessary to manually place the bag opening onto the machine's discharge port before feeding cement into the bag. However, since cement is a powder, a large amount of dust is generated during the feeding process, which can affect the health of nearby workers and pollute the environment. Therefore, further improvements are needed. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides the following technical solution: a cement packaging machine, comprising a fixed frame, a feeding machine mounted on the top of the fixed frame, a feeding hopper fixedly mounted on the top of the feeding machine, a belt conveyor positioned directly below the bottom of the feeding machine's discharge head, a sealing and dustproof component positioned on the top side of the middle section of the belt conveyor, and the sealing and dustproof component located directly below the feeding machine, the feeding machine's discharge head entering the interior of the sealing and dustproof component, and also including a bag support component mounted on the belt conveyor for supporting and positioning the packaging bag. By placing the packaging bag into the bag support component for support and positioning, it can move along the belt conveyor to the interior of the sealing and dustproof component, and then cement can be poured into the packaging bag through the feeding machine's discharge head. Since the filling is carried out within the sealed sealing and dustproof component, no dust will be emitted outwards.
[0005] As an optimization, the sealing and dustproof assembly includes a sealed box fixedly installed on the top side of the belt conveyor. The front of the sealed box is provided with a transparent observation window, and both sides of the sealed box are provided with automatically lifting and opening baffles. Infrared sensors for controlling the baffles are also provided on both sides of the sealed box. A weighing device is provided inside the belt conveyor corresponding to the center of the sealed box, and a dust suction device for suction is provided on the back of the sealed box. When the infrared sensors detect the passing of the packaging bag, the baffles will rise, thus facilitating the packaging bag to enter the sealing box and be filled below the discharge head.
[0006] As an optimization, the door stop includes door panels that are slidably inserted into both sides of the sealed box. Limiting strips are fixedly installed on both sides of the door panels. Limiting grooves are opened on the inner walls of both sides of the sealed box corresponding to the limiting strips. The limiting strips are slidably inserted into the inside of the limiting grooves. A screw is screwed to the center of the door panel. Servo motors are fixedly installed on both sides of the unloading machine. The top of the screw is fixedly installed at the bottom of the output shaft of the servo motor through a coupling. The servo motor is connected to an infrared sensor signal. By driving the door panel to lift and lower, it is convenient for the packaging bags to enter and exit.
[0007] As an optimization, the dust collection component includes an air extractor, an air extraction pipe, and a dust collection hood. The air extraction pipe is connected between the air extraction port of the air extractor and the dust collection hood, and the dust collection hood is fixedly installed inside the sealed box. A dust collection box is connected to the exhaust port of the air extractor through a flexible hose. The dust raised in the sealed box is sucked up and collected in the dust collection box.
[0008] As an optimization, the bag support assembly includes a bottom ring, four support rods and a top ring. The support rods are fixedly installed between the bottom ring and the top ring. It also has a locking plate that is snapped onto the outside of the top ring to position the edge of the packaging bag. The locking plate positions the packaging bag to facilitate filling.
[0009] As an optimization, the clamping plate includes a flexible clamp, and a pull rod is fixedly installed in the middle of the clamp.
[0010] The beneficial effects of this utility model are: This cement processing packaging machine positions the packaging bag by rolling the edge of the bag around the outside of the top ring and then clamping it with a clamp. This keeps the bag opening open for easy filling. Since the filling takes place in a sealed box, it prevents internal dust from spreading outward, thus achieving a dustproof effect and preventing dust from affecting the health of workers.
[0011] This cement processing packaging machine uses a servo motor to drive the screw to rotate in the middle of the door panel, which in turn lifts the door panel to open the sealed box, facilitating the entry and exit of packaging bags. The bags are then accurately filled using a weighing device. By activating the exhaust fan, air is drawn along the exhaust pipe, which then sucks in the dust from the sealed box through the dust extraction hood and collects it in the dust collection box, thus further preventing dust from escaping.

[0014] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1 A cement packaging machine includes a fixed frame 1, a feeding machine 2 mounted on the top of the fixed frame 1, a feeding hopper 3 fixedly mounted on the top of the feeding machine 2, a belt conveyor 4 located directly below the bottom of the discharge head of the feeding machine 2, a sealing and dustproof component 5 located on the top side of the middle of the belt conveyor 4, and the sealing and dustproof component 5 located directly below the feeding machine 2. The discharge head of the feeding machine 2 passes into the interior of the sealing and dustproof component 5. The machine also includes a bag support component 6 mounted on the belt conveyor 4 for supporting and positioning the packaging bag. The packaging bag is placed into the bag support component 6 for support and positioning, and then moves along the belt conveyor 4 to the interior of the sealing and dustproof component 5. Cement is then poured into the packaging bag through the discharge head of the feeding machine 2. Afterward, the bag moves along the belt conveyor 4 to the sealing stage. Since the filling is carried out inside the sealed sealing and dustproof component 5, dust will not be emitted outward, thus avoiding dust affecting the health of the workers. Please see Figure 2The sealing and dustproof assembly 5 includes a sealing box 7 fixedly installed on the top side of the belt conveyor 4. The front of the sealing box 7 is provided with a transparent observation window 8. Both sides of the sealing box 7 are provided with automatically lifting and opening baffles. Infrared sensors for controlling the baffles are also provided on both sides of the sealing box 7. A weighing device is provided inside the belt conveyor 4 corresponding to the center of the sealing box 7. A dust suction device for suctioning dust is provided on the back of the sealing box 7. When the infrared sensor detects the passing of the packaging bag, the baffles will rise, allowing the packaging bag to enter the sealing box 7 below the discharge head and above the weighing device. At this time, the belt conveyor 4 stops, and cement can be filled into the packaging bag through the discharge head. When the specified weight is reached, the weighing device transmits a signal to control the baffles and the belt conveyor 4 to start, so that the filled packaging bag can be moved out to the sealing stage. Please see Figure 2 The door stop includes door panels 9 that are slidably inserted into both sides of the sealed box 7. Limiting strips 10 are fixedly installed on both sides of the door panels 9. Limiting grooves 11 are opened on the inner walls of both sides of the sealed box 7 corresponding to the limiting strips 10. The limiting strips 10 are slidably inserted into the inside of the limiting grooves 11. A screw 12 is screwed into the center of the door panel 9. Servo motors 13 are fixedly installed on both sides of the unloading machine 2. The top end of the screw 12 is fixedly installed at the bottom end of the output shaft of the servo motor 13 through a coupling. The servo motor 13 is connected to the infrared sensor signal. By starting the servo motor 13, the screw 12 will rotate in the middle of the door panel 9, which will drive the door panel 9 to rise and fall, so as to automatically lift and open, making it convenient for the packaging bags to enter and exit. Please see Figure 2 The dust collection component includes a vacuum pump 14, a vacuum pipe 15, and a dust collection hood 16. The vacuum pipe 15 is connected between the air intake of the vacuum pump 14 and the dust collection hood 16, and the dust collection hood 16 is fixedly installed inside the sealed box 7. The exhaust port of the vacuum pump 14 is connected to a dust collection box 17 through a flexible hose. By starting the vacuum pump 14, air can be drawn along the vacuum pipe 15, which will then draw the dust from the sealed box 7 from the dust collection hood 16 and collect it in the dust collection box 17, thereby further preventing dust from being stirred up. Please see Figure 3 The bag support assembly 6 includes a bottom ring 18, four support rods 19, and a top ring 20. The support rods 19 are fixedly installed between the bottom ring 18 and the top ring 20. It also has a clamping plate for positioning the edge of the packaging bag by clamping it on the outside of the top ring 20. The clamping plate includes an elastic clamp 21. A pull rod 22 is fixedly installed in the middle of the clamp 21. By rolling the edge of the packaging bag to the outside of the top ring 20 and then clamping the clamping plate on the outside of the top ring 20, the packaging bag can be positioned to facilitate filling.
[0017] In use, first roll the edge of the packaging bag around the outside of the top ring 20, then clamp the clamp 21 around the outside of the top ring 20 to position the packaging bag, so that the bag opening is always open for easy filling. Then the packaging bag can be transported by the belt conveyor 4. When it passes the infrared sensor, the servo motor 13 is started to drive the screw 12 to rotate in the middle of the door panel 9, so that the door panel 9 will rise up to open the sealing box 7, and the packaging bag can be transported to the bottom of the discharge head in the sealing box 7 and above the weighing device. At this time, the belt conveyor 4 stops, and the door panels 9 on both sides will return to their original position to form a sealed space, and the weighing device will accurately fill the bag. During the filling process, by starting the vacuum pump 14, air can be drawn along the vacuum pipe 15, which will then suck the dust from the sealed box 7 through the dust extraction hood 16 and collect it in the dust collection box 17 to further prevent dust from being generated. After filling is completed, the door panel 9 can be lifted again and the belt conveyor 4 can be started to move the filled packaging bag to the next sealing stage.
[0018] In summary, this cement processing packaging machine can position the packaging bag by rolling the edge of the packaging bag around the outside of the top ring 20 and then clamping the clamp 21 around the outside of the top ring 20, so that the opening of the packaging bag is always open, which is convenient for filling. Moreover, since the filling is carried out in a sealed box 7, it can prevent the internal dust from spreading outward, thus playing a role in sealing and dust prevention, and avoiding dust from affecting the health of workers. By starting the servo motor 13, the screw 12 rotates in the middle of the door panel 9, which in turn causes the door panel 9 to rise and open the sealed box 7, facilitating the entry and exit of packaging bags. The bags are then accurately filled using a weighing device. By starting the vacuum pump 14, air is drawn along the vacuum pipe 15, which then sucks the dust from the sealed box 7 through the dust extraction hood 16 and collects it in the dust collection box 17, thereby further preventing dust from being generated.
