Description
Technical Field
[0001] The utility model relates to the technical field of cement production, in particular to a cement production packaging machine. Background Art
[0002] With the acceleration of current construction projects, the demand for cement is increasing, but finished cement is in a scattered state and is more suitable for large-scale projects. In order to facilitate the storage of cement and to be suitable for small-scale projects with small sites and small amounts, cement is usually packaged, so cement packaging machines are used more and more frequently.
[0003] In the production process of cement, the measurement and packaging links are particularly critical. Although the traditional belt scale can achieve quantitative transportation of cement to a certain extent, due to its limited carrying capacity, the belt is prone to wear and breakage after long-term operation, and the replacement frequency is high, which seriously affects the continuity and production efficiency of the production line. In addition, the maintenance cost of the belt scale is high. Once a failure occurs, the maintenance cycle is long, which has a great impact on the entire production process.

DETAILED DESCRIPTION
[0021] The following description is only a preferred embodiment of the cement production packaging machine, and does not limit the protection scope of the utility model. Example 1
[0022] A cement production packaging machine, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a support frame 1, a protection box 2, a storage table 3, a body 4, a feed port 5, a pressure block 8, a spring 9, a push rod 10, a limit block 11, a sensor 12, and a fixed ring 14. The storage table 3 is installed on the four support frames 1. The body 4 is installed on the storage table 3. The body 4 is provided with a feed port 5 on the top. The top of the feed port 5 is provided with a fixed ring 14. A protection box 2 is placed on the bottom right of the storage table 3. A pressure block 8 is slidably penetrated on the top of the protection box 2. A push rod 10 is installed at the bottom of the pressure block 8. A spring 9 is sleeved on the push rod 10. The inside of the protection box 2 A cylinder is placed below the push rod 10, and a groove is opened on the cylinder. The upper end of the spring 9 is fixed on the push rod 10, and the lower end of the spring 9 is installed on the top of the cylinder. A limit block 11 is movably arranged in the groove of the cylinder to limit the downward movement range of the push rod 10. For example, the standard weight of a bag of cement should be 50KG. When the limit block 11 is placed on the second layer, it is the standard weight. A sensor 12 is installed on the limit block 11. The push rod 10 is slidably inserted into the groove of the cylinder and contacts with the sensor 12. The push rod 10 presses the sensor 12 downward to send a signal.
[0023] like Figure 1 , Figure 3 and Figure 6As shown, it also includes a guide column 6, a bellows 15, a screw rod 7, a second motor 25, an observation window 13 and a receiver 26. The second motor 25 is installed in the body 4, and the receiver 26 is installed on the second motor 25. The output shaft of the second motor 25 is connected to the screw rod 7 through a coupling. The guide column 6 is installed on the outer wall of the screw rod 7. The guide column 6 serves to guide the cement. The front end of the guide column 6 is sleeved with a bellows 15. The cylindrical thin-walled corrugated shell with multiple transverse corrugations on the bellows 15 is elastic. Pressing or pulling the bellows 15 can cause it to move. Observation windows 13 for observing the screw rod 7 are set on the left and right sides of the body 4.
[0024] The staff uses the fixing ring 14 to connect and fix the feeding pipe with the feeding port 5 of the packaging machine, adjusts the limit block 11 to the slot of the corresponding weight, turns on the power, and the cement enters the machine body 4 from the feeding port 5. At this time, the second motor 25 works to drive the screw rod 7 to rotate. Under the action of the guide column 6, the cement is transmitted to the bellows 15 along the screw groove of the screw rod 7, and then poured into the packaging bag through the bellows 15. As the weight of the packaging bag becomes heavier, the pressing block 8 squeezes it downward under the gravity of the cement in the packaging bag. At this time, the push rod 10 is inserted into the groove of the cylinder until it is squeezed to the sensor 12 on the limit block 11. At this time, the sensor 12 transmits an electrical signal to be received by the receiver 26, and controls the motor to stop working, the feeding pipe stops feeding, and the staff observes the state of the screw rod 7 through the observation window 13. When the screw rod 7 no longer rotates to transport cement, it indicates that the cement in the packaging bag has reached the filling weight standard. Example 2
[0025] On the basis of Example 1, Figure 3 and Figure 4 As shown, it also includes a mounting frame 16, a first sliding rod 17, a second sliding rod 1701, a fixed block 18, a hook 19 and a U-shaped block 20. The mounting frame 16 is installed on the support frame 1 on the right side of the storage table 3, and the U-shaped block 20 is installed on the mounting frame 16. The first sliding rod 17 and the second sliding rod 1701 are installed on the left and right ends of the U-shaped block 20. The first sliding rod 17 and the second sliding rod 1701 both slide along the mounting frame 16, and the second sliding rod 1701 is installed on the fixed block 18. The bottom end of the corrugated tube 15 is installed on the circular ring of the fixed block 18, and a plurality of hooks 19 for unfolding and hanging the opening of the packaging bag are installed around the bottom of the circular ring of the fixed block 18.
[0026] like Figure 5As shown, it also includes a screw 21, a first bevel gear 22, a second bevel gear 23 and a first motor 24. A long strip block (not shown in the figure) is installed on the support frame 1 on the front side of the storage table 3. The first motor 24 is installed on the long strip block. The output shaft of the first motor 24 is connected to the second bevel gear 23 through a coupling. The second bevel gear 23 is meshed with the first bevel gear 22. A screw 21 is installed on the central axis of the first bevel gear 22, and the U-shaped block 20 is threadedly installed on the screw 21.
[0027] When the sizes of packaging bags are different, it is necessary to adjust the height of the hook 19 to adapt to the packaging bags. At this time, the first motor 24 works, the second bevel gear 23 rotates and engages with the first bevel gear 22, and the screw 21 rotates with the first bevel gear 22. The U-shaped block 20 threadedly mounted on the screw 21 drives the first sliding rod 17 and the second sliding rod 1701 to move up and down, thereby adjusting the height of the hook 19 so that when the bottom of the packaging bag is placed on the pressing block 8, the mouth of the packaging bag can be hung by the hook 19.
