Abstract
Description
Technical Field
[0001] This utility model relates to the field of mortar production and bagging technology, and in particular to a quantitative bagging device for mortar production. Background Technology
[0002] In construction, mortar is an indispensable material used for bricklaying, plastering, and tile bonding. Mortar production equipment for quantitative bagging is used to package mortar produced in the factory into bags of specific specifications. This step is of great significance. On the one hand, packaged mortar is easy to store and transport, reducing losses during handling and extending its shelf life. On the other hand, standardized bagged mortar allows construction workers to accurately control the amount used, improving construction efficiency and avoiding waste or delays caused by improper material usage.
[0003] Current quantitative bagging equipment uses a screw conveyor to transport materials from the hopper during bagging. As a result, the amount of material inside the hopper decreases continuously during the material transport process, and when the material height is lower than the screw conveyor, it cannot be effectively collected at the screw conveyor.
[0004] This results in low efficiency in the material conveying and bagging process, and some material will remain at the bottom of the silo after all the material is bagged, causing material waste.
[0005] To address this issue, this utility model proposes a quantitative bagging device for mortar production. Utility Model Content
[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0007] Therefore, the purpose of this utility model is to provide a quantitative bagging device for mortar production, including a main cabinet and a weighing platform. A hopper is fixedly connected to the top of the main cabinet, a bagging cylinder is provided at the bottom of the hopper, and two support plates are fixedly connected to one side of the hopper.
[0008] The support plate is rotatably connected to a rotating shaft inside. Two driving pulleys are fixedly connected to the outside of the rotating shaft. Two driven pulleys are rotatably connected to the outside of the two driving pulleys via a belt. A rotating drum is fixedly connected to the inside of the driven pulleys. The outside of the rotating drum is rotatably connected to the inside of the hopper.
[0009] The rotating drum is internally threaded with a screw rod, which is externally located inside the hopper. One end of the screw rod is fixedly connected to a collecting plate, and a limiting slide plate is fixedly connected to one side of the collecting plate. The external side of the limiting slide plate is slidably connected to the inside of the hopper.
[0010] Preferably, in any of the above solutions, a first motor is provided on the top of one of the support plates, and the output end of the first motor is fixedly connected to one end of the rotating shaft.
[0011] Preferably, of any of the above embodiments, a feed shell is fixedly connected to the top of the silo, a partition is fixedly connected to the inside of the silo, and a maintenance door is hinged to one side of the silo.
[0012] Preferably, in any of the above embodiments, two conveying cylinders are fixedly connected inside the partition, a discharge pipe is provided at the bottom of the conveying cylinder, the discharge pipe is located inside the bagging cylinder, and two rotating shafts are rotatably connected inside the hopper.
[0013] Preferably, in any of the above embodiments, the outside of the rotating shaft is rotatably connected to the inside of the conveying cylinder, and a spiral conveying plate is fixedly connected to the outside of the rotating shaft.
[0014] Preferably, one of the above solutions is that two second motors are provided on one side of the hopper, and the output end of the second motor is fixedly connected to one end of the rotating shaft.
[0015] Preferably, one side of the main unit cabinet is hinged with an access door, and the other side of the main unit cabinet is equipped with a display.
[0016] The technical effect achieved by adopting the above solution is that the weight of the material being bagged can be displayed in real time on the monitor for personnel to view.
[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:
[0018] Because the quantitative bagging equipment transports the material in the hopper through a screw conveyor plate when bagging the material, the material inside the hopper decreases continuously during the material transport process. When the material height is lower than the screw conveyor plate, it cannot be effectively gathered at the screw conveyor plate. This results in low transport efficiency and some material remains at the bottom of the hopper after all the material is bagged, causing material waste.
[0019] The material collection plate can be used to concentrate the material inside the silo. During material conveying, the material collection plate moves continuously towards the center to concentrate the remaining material, which facilitates the material conveying and bagging process. This solves the problems of low efficiency and material waste in material conveying and bagging, and helps to improve the working efficiency of quantitative bagging equipment for material bagging.

[0029] Example 1: As Figures 1 to 6 As shown, a quantitative bagging device for mortar production includes a main cabinet 1 and a weighing platform 2. The main cabinet 1 is equipped with electronic equipment to control the bagging and weighing operations. The weighing platform 2 is a known technology, and the technology is currently very mature. Those skilled in the art can and should understand its specific functions and structure, so it will not be described in detail here. When bagging materials, the electronic equipment inside the main cabinet 1 can control the large and small double spiral conveyor plates 20 to perform two feeding methods, coarse feeding and fine feeding, to ensure the working accuracy of the quantitative bagging device. The weighing platform 2 is also used to detect the weight of the material in real time when bagging. A hopper 4 is fixedly connected to the top of the main cabinet 1, and a bagging cylinder 5 is set at the bottom of the hopper 4. Two support plates 6 are fixedly connected to one side of the hopper 4. The two support plates 6 are L-shaped and square, respectively. The L-shaped support plate 6 is convenient for installing the motor, so the first motor 14 is set on the L-shaped support plate 6.
[0030] A rotating shaft 7 is rotatably connected inside the support plate 6. Two driving pulleys 8 are fixedly connected to the outside of the rotating shaft 7. Two driven pulleys 9 are rotatably connected to the outside of the two driving pulleys 8 via belts. A rotating drum 10 is fixedly connected inside the driven pulleys 9. The outside of the rotating drum 10 is rotatably connected to the inside of the hopper 4. The output end of the first motor 14 can drive the rotating shaft 7 to rotate. The rotating shaft 7 rotates inside the support plate 6, which drives the driving pulleys 8 to rotate. The driving pulleys 8 drive the driven pulleys 9 to rotate synchronously via belts. At this time, the driven pulleys 9 drive the rotating drum 10 to rotate. It should be noted that a retaining ring is provided on one side of the rotating drum 10. When the rotating drum 10 rotates, the retaining ring will rotate inside the hopper 4, so that the rotating drum 10 rotates inside the hopper 4 and thus maintains a relatively fixed position when rotating.
[0031] A screw 11 is internally threaded onto the rotating drum 10. The screw 11 is externally located inside the hopper 4. One end of the screw 11 is fixedly connected to a collecting plate 12. A limiting slide plate 13 is fixedly connected to one side of the collecting plate 12. The limiting slide plate 13 is slidably connected to the inside of the hopper 4. Because the screw 11 is externally threaded onto the rotating drum 10, the screw 11 moves inside the rotating drum 10 when the rotating drum 10 rotates. Simultaneously, the movement of the screw 11 inside the hopper 4 drives the collecting plate 12 to move. The movement of the collecting plate 12 also causes the limiting slide plate 13 to slide inside the hopper 4. Plate 13 limits the movement distance of the collecting plate 12 to prevent excessive movement of the collecting plate 12 and collision with the screw conveyor plate 20. It should be noted that the external threads of the two screws 11 are opposite, so that when the drum 10 rotates, the two screws 11 will move in opposite directions synchronously, thereby realizing that the two collecting plates 12 will move towards the center or move outward to reset synchronously. The collecting plate 12 can concentrate the material inside the hopper 4. During material conveying, the collecting plate 12 continuously moves towards the center to continuously concentrate the remaining material, which facilitates the bagging of materials and helps to improve the working efficiency of the quantitative bagging equipment for bagging materials.
[0032] Furthermore, because the two spiral conveyor plates 20 are of different sizes, the thicknesses of the two collecting plates 12 are also set differently. The collecting plate 12 on the side closer to the larger spiral conveyor plate 20 is relatively thinner, while the collecting plate 12 on the side closer to the smaller spiral conveyor plate 20 is relatively thicker. This is mainly to compensate for the distance difference caused by the different sizes of the two spiral conveyor plates 20 when the two collecting plates 12 move synchronously. By setting the thicknesses of the two collecting plates 12 differently, it can be prevented that when the collecting plate 12 on the side of the larger spiral conveyor plate 20 moves to its limit distance, there will still be a certain distance between the collecting plate 12 on the other side and the smaller spiral conveyor plate 20. This would prevent the material on the side of the smaller spiral conveyor plate 20 from being properly concentrated and conveyed.
[0033] One of the support plates 6 has a first motor 14 on its top, and the output end of the first motor 14 is fixedly connected to one end of the rotating shaft 7.
[0034] The top of the silo 4 is fixedly connected to the feed shell 15, and the inside of the silo 4 is fixedly connected to the partition 16. A maintenance door is hinged to one side of the silo 4. When using the quantitative bagging equipment, the material to be bagged is transported to the feed shell 15 by the conveying device. The material is added into the silo 4 through the feed shell 15. After the material is bagged, it is transferred to the conveyor belt to be transported to the next process.
[0035] Two conveying cylinders 17 are fixedly connected inside the partition 16. A discharge pipe 18 is provided at the bottom of the conveying cylinder 17. The discharge pipe 18 is located inside the bagging cylinder 5. Two rotating shafts 19 are rotatably connected inside the hopper 4.
[0036] The rotating shaft 19 is rotatably connected to the inside of the conveying cylinder 17. A spiral conveyor plate 20 is fixedly connected to the outside of the rotating shaft 19. The output ends of the two second motors 21 drive the rotating shaft 19 to rotate, which in turn drives the spiral conveyor plate 20 to rotate, thus conveying the material inside the hopper 4 to the inside of the conveying cylinder 17. When the material is fed inside the conveying cylinder 17, it will pass through the discharge pipe 18 and enter the bagging cylinder 5. At this time, the material is added into the packaging bag through the bagging cylinder 5. It should be noted that the two spiral conveyor plates 20 are of different sizes, so that the functions of coarse and fine processing of the material can be realized. When the material is first bagged, the two spiral conveyor plates 20 rotate rapidly in sync to quickly convey the material for coarse processing and bagging. When the material weighing is about to reach the set range, the large spiral conveyor plate 20 stops working, and the small spiral conveyor plate 20 works slowly to fine process the material.
[0037] Two second motors 21 are installed on one side of the hopper 4, and the output end of the second motor 21 is fixedly connected to one end of the rotating shaft 19.
[0038] One side of the main unit cabinet 1 is hinged with an inspection door, and the other side of the main unit cabinet 1 is equipped with a display 3. The display 3 can display the weight of the material when it is bagged in real time for personnel to check.
[0039] A quantitative bagging device for mortar production, the working principle of which is as follows:
[0040] First, when using the quantitative bagging equipment, the material to be bagged is transported to the feed shell 15 by the conveying device. The material is added into the hopper 4 through the feed shell 15. When bagging the material, the packaging bag is manually opened and placed outside the bagging cylinder 5.
[0041] Secondly, the output ends of the two second motors 21 drive the rotating shaft 19 to rotate, thereby driving the screw conveyor plate 20 to rotate and transport the material inside the hopper 4 to the inside of the conveying cylinder 17. When the material is fed inside the conveying cylinder 17, it will pass through the discharge pipe 18 and enter the inside of the bagging cylinder 5. At this time, the material is added into the inside of the packaging bag through the bagging cylinder 5. When the material is filled into the packaging bag, the weighing platform 2 will weigh it in real time. The weight of the material when it is bagged can be displayed in real time through the display 3 for personnel to check.
[0042] Finally, the output of the first motor 14 drives the rotating shaft 7 to rotate. The rotating shaft 7 rotates inside the support plate 6, which in turn drives the drive pulley 8 to rotate. The drive pulley 8 then drives the driven pulley 9 to rotate synchronously via a belt. At this time, the driven pulley 9 drives the rotating drum 10 to rotate. Because the screw 11 is threadedly connected to the inside of the rotating drum 10, the screw 11 moves inside the rotating drum 10 when the drum 10 rotates. Simultaneously, the screw 11 moves inside the hopper 4, which in turn drives the collecting plate 12 to move. The collecting plate 12 can concentrate the material inside the hopper 4. During material conveying, the collecting plate 12 continuously moves towards the center to continuously concentrate the remaining material, which facilitates the bagging of materials and improves the working efficiency of the quantitative bagging equipment. After the material is bagged, it is transferred to the conveyor belt for conveying to the next process.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
