Description

Technical Field

[0001] This utility model relates to the field of cement packaging technology, and in particular to a dust-proof cement packaging device. Background Technology

[0002] Cement is a powdery 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. It is the most common material in various engineering projects. After production, cement needs to be packaged for convenient transportation and sale, so packaging equipment is required.

[0003] In existing cement bagging equipment, workers typically place the bag under the cement storage device after positioning it, open the discharge device, and the cement automatically falls into the bag. Workers then remove the bag and seal it. However, this method does not seal the discharge port and the bag, generating a large amount of dust during the cement's descent. This dust can easily be inhaled by workers, affecting their health. Furthermore, the large amount of dust floating in the workshop poses a potential risk of dust explosion. Therefore, there is room for improvement. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figure 1 , Figure 2 and Figure 3 A dust-proof cement packaging device includes a base frame 1, a drive assembly fixedly connected to the right side of the base frame 1, a support frame 2 fixedly connected to the back of the base frame 1, a circular hole on the upper surface of the support frame 2, a storage cylinder 3 fixedly connected to the inner wall of the circular hole, a feed hopper 4 fixedly connected to the top of the storage cylinder 3, a sealing cap 5 threadedly connected to the inner wall of the feed hopper 4, a discharge assembly slidably connected to the inner wall of the storage cylinder 3, and a groove on the front of the support frame 2, with a dustproof assembly slidably connected to the inner wall of the groove.

[0024] The drive component is used for loading and unloading packaging bags, the unloading component is used for automatic cement unloading, and the dustproof component is used to reduce the dust generated during the cement unloading process.

[0025] The drive assembly includes a first servo motor 6, the output end of which is fixedly connected to a threaded rod 7. A strip groove is formed on the upper surface of the bottom frame 1. The left end of the threaded rod 7 is rotatably connected to the inner wall of the strip groove. A strip frame 8 is slidably connected to the inner bottom wall of the strip groove. Two circular discs 9 are fixedly connected to the upper surface of the strip frame 8. Packaging bag clamps 10 are fixedly connected to the upper surface of each of the two circular discs 9. The first servo motor 6 can drive the strip frame 8 to move left and right in the strip groove through the threaded rod 7. When the strip frame 8 moves to the rightmost position, the left packaging bag clamp 10 moves to the position below the feeding assembly. When the strip frame 8 moves to the leftmost position, the right packaging bag clamp 10 moves to the position below the feeding assembly. This enables the two packaging bag clamps 10 to perform synchronous feeding and feeding operations, thereby improving the efficiency of cement packaging.

[0026] The feeding assembly includes a feeding sleeve 11, the surface of which has an arc-shaped groove. The diameter of the feeding sleeve 11 is smaller than the diameter of the packaging bag clamp 10. Two limiting grooves are formed on the inner wall of the storage cylinder 3. Two limiting blocks 12 are fixedly connected to the surface of the feeding sleeve 11, and the two limiting blocks 12 are slidably connected to the inner walls of the two limiting grooves respectively. A feeding disc 13 is fixedly connected to the inner wall of the feeding sleeve 11. A feeding hole is formed on the upper surface of the feeding disc 13, and a cavity is formed inside the feeding disc 13. An electric push rod 14 is fixedly connected to the inner wall of the storage cylinder 3. A baffle 15 is fixedly connected to the output end of the electric push rod 14. The position of the baffle 15 corresponds to the position of the discharge hole. The size of the baffle 15 is larger than the size of the discharge hole. The discharge sleeve 11 can move up and down on the inner wall of the storage cylinder 3 through two limit blocks 12. At the same time, after the electric push rod 14 is started, it can drive the baffle 15 to extend and retract. When the baffle 15 retracts, the cement in the storage cylinder 3 falls through the discharge hole. When the baffle 15 extends, it can block the cement from falling.

[0027] Example 2: Refer to Figure 1 and Figure 4The dustproof assembly includes a movable block 16, a strip frame 17 fixedly connected to the front of the movable block 16, a moving groove on the front of the strip frame 17, a positioning rod 18 fixedly connected to the inner top wall of the moving groove, a spring 19 sleeved on the surface of the positioning rod 18, a rectangular block 20 slidably connected to the inner wall of the moving groove, the rectangular block 20 slidably connected to the surface of the positioning rod 18, the top end of the spring 19 overlaps with the lower surface of the rectangular block 20, the bottom end of the spring 19 overlaps with the inner bottom wall of the moving groove, a connecting rod 21 fixedly connected to the front of the rectangular block 20, the front end of the connecting rod 21 fixedly connected to the surface of the feeding sleeve 11, and a hydraulic cylinder 22 fixedly connected to the back of the support frame 2. A transmission plate 23 is fixedly connected to the back of the rectangular block 20. The transmission plate 23 passes through the moving groove and the slide groove. The length of the transmission plate 23 is greater than the length of the movable block 16. The output shaft of the hydraulic cylinder 22 is fixedly connected to the upper surface of the transmission plate 23. The hydraulic cylinder 22 can drive the strip frame 17 to move down as a whole through the transmission plate 23. When the movable block 16 moves to the bottom of the slide groove, the hydraulic cylinder 22 can drive the rectangular block 20 to move down. The rectangular block 20 can drive the feeding sleeve 11 to move down through the connecting rod 21. At the same time, it squeezes the spring 19 on the surface of the positioning rod 18. The feeding sleeve 11 can extend into the inside of the packaging bag, thereby avoiding a large amount of leakage during the cement feeding process.

[0028] A positioning frame 24 is fixedly connected to the front of the strip frame 17. A second servo motor 25 is fixedly connected to the right side of the positioning frame 24. A positive and negative threaded rod 26 is fixedly connected to the output end of the second servo motor 25. A slot is formed on the front of the positioning frame 24. The left end of the positive and negative threaded rod 26 is rotatably connected to the inner wall of the slot. Two grippers 27 are slidably connected to the inner wall of the slot. Both grippers 27 are adapted to the arc-shaped groove. The two grippers 27 are threaded to the positive and negative threads on the surface of the positive and negative threaded rod 26, respectively. Next, when the strip frame 17 moves down to the bottom, the height of the two grippers 27 is lower than the height of the top of the packaging bag clamp 10. At the same time, after the second servo motor 25 is started, it can drive the two grippers 27 to move towards the middle through the positive and negative threaded rods 26 until the two grippers 27 can press the packaging bag into the arc groove on the surface of the feeding sleeve 11, thereby improving the sealing between the packaging bag and the feeding sleeve 11, reducing the dust generated during the cement feeding process, and improving the protection effect for workers.

[0029] Working principle: First, the packaging bag is placed on the packaging bag clamp 10. The circular ring on the packaging bag clamp 10 restricts the bag opening. At this time, the first servo motor 6 starts, driving the strip frame 8 to move to the left through the threaded rod 7. The packaging bag clamp 10 with the packaged bag moves to the position below the feeding sleeve 11, while the other packaging bag clamp 10 moves to the other end, making it convenient for the staff to place another packaging bag. At this time, the hydraulic cylinder 22 starts, driving the strip frame 17 to descend through the transmission plate 23. When the strip frame 17 drives the movable block 16 to the bottom of the chute, the hydraulic cylinder 22 continues to extend, and through the transmission plate... 23 drives the rectangular block 20 to move downwards. The rectangular block 20 can drive the feeding sleeve 11 to move downwards via the connecting rod 21. At the same time, the rectangular block 20 can compress the spring 19 during the downward movement, causing it to deform. When the strip frame 17 moves to the bottom, the two grippers 27 can move to the lower side of the ring above the packaging bag hoop 10. When the rectangular block 20 moves to the bottom, the feeding sleeve 11 extends into the packaging bag. At the same time, the arc groove corresponds to the position of the two grippers 27. The second servo motor 25 starts and drives the two grippers 27 to move towards the middle via the positive and negative threaded rods 26. The two grippers 27 can press the surface of the packaging bag tightly against the arc groove. In the groove, the sealing effect between the packaging bag and the surface of the feeding sleeve 11 is improved. At this time, the electric push rod 14 opens and drives the baffle 15 to disengage from the feeding hole. The cement in the storage cylinder 3 can automatically fall into the packaging bag, completing the cement packaging operation. Due to the clamping effect of the two claws 27, the packaging bag is tightly sealed with the feeding sleeve 11. Therefore, the dust generated during the feeding process will not float directly in the air, but will dissipate directly inside the packaging bag, thus achieving a good dust prevention effect and avoiding the health impact of workers from inhaling large amounts of dust. After the packaging is completed, the electric push rod 14 drives the baffle 15 to extend and block the feeding hole. The second servo motor 25 drives the two grippers 27 to detach from the surface of the packaging bag via the positive and negative threaded screws 26. At the same time, the hydraulic cylinder 22 drives the transmission plate 23 to rise. The rectangular block 20 moves upward first, thereby raising the feeding sleeve 11. When the rectangular block 20 moves to the top, the hydraulic cylinder 22 continues to retract. The rectangular block 20 can drive the strip frame 17 to move upward as a whole, and make the position of the two grippers 27 higher than the packaging bag hoop 10. At this time, the first servo motor 6 starts, driving the strip frame 8 to move to the right. The packaged bag moves to the right position after being packaged, while the left packaging bag moves to the feeding sleeve 11 position. The above operation can be repeated.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
