Description

Technical Field

[0001] This utility model relates to the field of cement product manufacturing equipment technology, and in particular to a high-pressure column forming machine. Background Technology

[0002] A column forming machine is a piece of equipment used to manufacture columns. There are several types, including push-type cement column forming machines, high-pressure forming machines, and precast concrete column forming machines. Column forming machines are used in concrete manufacturing because they can precisely proportion and mix raw materials, mold concrete and other materials into columns using molds, and utilize vibration systems to make the slurry more compact, ensuring the density and strength of the columns. They also enable automated control, improving production efficiency, saving manpower and resources, and producing high-quality columns that meet the needs of various fields such as construction, roads, and agriculture.

[0003] The column forming machine mainly consists of a mixing system, a feeding system, a mold forming system, and a control system. Its working principle is that the mixed raw materials (such as cement, sand, etc.) are precisely proportioned and fully mixed by the mixing system, and then sent to the mold forming system through the feeding system, so that the raw materials are arranged more tightly in the mold, improving the density and strength. The entire process is automated by the control system.

[0004] In existing technologies, some column forming machines require concrete to be fed into a mold and wait for the mold to solidify the concrete. However, when the concrete is fed into the mold, air can enter the concrete and form air bubbles, resulting in voids inside the concrete and affecting the quality of concrete production. To address this issue, a high-pressure column forming machine is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-pressure column forming machine, which aims to improve the problem in the prior art where air enters the concrete when it is fed into the mold, forming air bubbles, resulting in voids in the concrete and affecting the quality of concrete production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-pressure column forming machine includes a base plate. A connecting column is rotatably connected to the left side of the base plate. Cams are fixedly connected to both the front and rear ends of the connecting column. A motor is fixedly connected to the outside of the front end of the cam. A connecting plate is fixedly connected to the outside of the cam. A bearing plate is fixedly connected to the other end of the connecting plate. A limit component is provided on the outside of the bearing plate to limit the bearing plate. Two adjustment components are provided on the right side of the base plate to flexibly adapt to processing requirements.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes multiple fixing plates. The outer sides of the fixing plates are fixedly connected to the front and rear sides of the bearing plate, and the other end of the fixing plates is fixedly connected to the front and rear sides of the base plate. A feeding hopper is fixedly connected to the top of the bearing plate.

[0010] As a further description of the above technical solution:

[0011] A storage box is fixedly connected to the top left side of the base plate, a motor is fixedly connected to the left side of the storage box, and a conveying auger is fixedly connected to the drive end of the motor.

[0012] As a further description of the above technical solution:

[0013] The external rotatable connection of the conveying auger is to the inside of the storage box. The top of the storage box is fixedly connected to the inlet, and the bottom right side of the storage box is provided with the outlet.

[0014] As a further description of the above technical solution:

[0015] A connecting frame is fixedly connected to the outside of the base plate, a hydraulic cylinder is fixedly connected to the inside of the connecting frame, a pressure plate is fixedly connected to the drive end of the hydraulic cylinder, and the outside of the pressure plate is in contact with the inner wall of the feed hopper.

[0016] As a further description of the above technical solution:

[0017] A mold is provided on the top of the base plate. Two rotating rods are rotatably connected to the front and rear sides of the mold. Side plates are hinged to the left and right sides of the outside of the mold. The front and rear sides of the side plates are provided with slots. The outside of the rotating rods is engaged with the inner wall of the slots.

[0018] As a further description of the above technical solution:

[0019] The adjustment assembly includes an adjustment rod, the external thread of which is connected to the inside of the base plate. One end of the adjustment rod is fixedly connected to a handle, and the end of the adjustment rod away from the handle is fixedly connected to a blocking plate. Two limiting posts are fixedly connected to the side of the blocking plate near the adjustment rod, and springs are sleeved on the outside of the limiting posts.

[0020] As a further description of the above technical solution:

[0021] The base plate has two limiting grooves on its front and rear sides. The limiting post is slidably connected to the inner wall of the limiting groove. One end of the spring is fixedly connected to the outside of the limiting post, and the other end of the spring is fixedly connected to one side of the inner wall of the limiting groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor drives the connecting column to rotate, which in turn drives the cam to rotate at a constant speed. The protruding part of the cam periodically presses the connecting plate, causing the connecting plate to reciprocate and shake, which in turn causes the bearing plate to shake. Since the bearing plate is stably connected to the base plate through the fixing plate, the shaking of the bearing plate is transmitted to the base plate, which ultimately causes the mold placed on the base plate to shake violently. The concrete inside the mold is subjected to continuous and regular vibration, and the air can be quickly discharged, avoiding defects such as a large number of air holes and voids inside the concrete. It can ensure that the concrete evenly fills all corners of the mold in a short time, effectively reducing the hidden dangers such as column cracking and insufficient load-bearing capacity caused by concrete quality problems.

[0024] 2. In this utility model, the front and rear sides of the mold are engaged with the slots on the side plates via rotating rods. The rotating rods are connected to the mold by pins, ensuring flexible rotation and facilitating quick installation and disassembly of the mold. The high-precision machining of the slots ensures that the rotating rods are tightly fixed after insertion, effectively preventing horizontal displacement of the mold. During mold installation, the blocking plate tightly abuts against the mold, restricting mold shaking or displacement from the side. Together with the limiting of the rotating rods and slots, they form an all-round three-dimensional protection, enabling the mold to maintain accurate positioning even under multiple forces such as concrete filling, pressure plate extrusion, and base plate shaking, ensuring that the column forming dimensions meet the requirements. At the same time, the operation is simple and convenient, reducing the labor intensity of workers, improving production efficiency, and reducing the defect rate caused by mold displacement.

[0032] 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.

[0033] Reference Figures 1 to 2 This utility model provides an embodiment of a high-pressure column forming machine, including a base plate 1, which is the foundation of the entire forming machine. A connecting column 2 is rotatably connected to the left side inside the base plate 1. Cams 3 are fixedly connected to both the front and rear ends of the connecting column 2. The cams 3 are symmetrically fixedly connected to the front and rear ends of the connecting column 2 to ensure that the cams 3 will not loosen or fall off when rotating at high speed. A motor 2 is fixedly connected to the outside of the front cam 3, and a connecting plate 4 is fixedly connected to the outside of the cam 3. When the motor 2 is started, it drives the cam 3 to rotate at a uniform speed.

[0034] The protruding part of the cam 3 periodically presses the connecting plate 4. The other end of the connecting plate 4 is fixedly connected to the bearing plate 6. The bearing plate 6 is provided with a limiting component on its exterior. The limiting component can limit the bearing plate 6. The limiting component includes multiple fixing plates 5. The fixing plates 5 are fixedly connected to the front and rear sides of the bearing plate 6. During the operation of the equipment, the fixing plates 5 bear the lateral tension and pressure generated when the bearing plate 6 shakes. With its own strength and rigidity, the bearing plate 6 is firmly fixed above the base plate 1 to prevent the bearing plate 6 from shifting in the front-back or left-right directions.

[0035] The other end of the fixed plate 5 is fixedly connected to the front and rear sides of the base plate 1. A storage box 7 is fixedly connected to the top left side of the base plate 1. The storage box 7 is used to store materials to be processed. A motor 8 is fixedly connected to the left side of the storage box 7. The motor 8 serves as the power source for conveying materials in the storage box 7. A conveying auger 9 is fixedly connected to the drive end of the motor 8. When the motor 8 starts, it drives the central shaft of the conveying auger 9 to rotate, and the spiral blades rotate accordingly. The material at the bottom of the storage box 7 is pushed forward along the axis by the thrust of the spiral surface. The external rotatable connection of the conveying auger 9 is connected to the inside of the storage box 7. A feed inlet is fixedly connected to the top of the storage box 7, and a discharge outlet is opened on the bottom right side of the storage box 7. The material is discharged from the discharge outlet at the bottom of the storage box 7 under the squeezing and pushing of the spiral blades.

[0036] A connecting frame 10 is fixedly connected to the outside of the base plate 1, and a hydraulic cylinder 11 is fixedly connected inside the connecting frame 10. The hydraulic cylinder 11 is firmly fixed to the connecting frame 10 with bolts. The connecting frame 10 can withstand the reaction force generated by the hydraulic cylinder 11 during the extension and retraction process, preventing deformation of the connecting frame 10 or loosening of the connection with the base plate 1 due to uneven force. A pressure plate 12 is fixedly connected to the drive end of the hydraulic cylinder 11. The outside of the pressure plate 12 contacts the inner wall of the feeding hopper 13, which can evenly cover the upper opening of the feeding hopper 13 and apply uniform pressure to the concrete. The feeding hopper 13 is fixedly connected to the top of the bearing plate 6. The hydraulic cylinder 11 can achieve precise extension and retraction according to a preset program, converting hydraulic energy into mechanical energy, driving the pressure plate 12 to move downward and apply pressure to the concrete in the feeding hopper 13. A mold 14 is set on the top of the base plate 1, and the bearing plate 6 is located above the base plate 1, mainly used to support the feeding hopper 13 and support the mold 14.

[0037] Reference Figures 3 to 5 Two rotating rods 15 are rotatably connected to both the front and rear sides of the mold 14. The connection between the rotating rods 15 and the mold 14 adopts a pin structure, which allows the rotating rods 15 to rotate flexibly, facilitating the installation and disassembly of the mold 14. Side plates 16 are hinged to the left and right sides of the outside of the mold 14, serving as auxiliary closing structures for the mold 14.

[0038] The side plate 16 has slots 17 on both the front and rear sides. The outer side of the rotating rod 15 engages with the inner wall of the slot 17, and the slot 17 provides a locking and positioning function for the rotating rod 15. Two adjustment components are provided on the right side of the interior of the base plate 1. The adjustment components can flexibly adapt to processing requirements. The adjustment components include an adjustment rod 18, the outer side of which is threaded into the interior of the base plate 1. The adjustment rod 18 can fix and disassemble the mold 14.

[0039] One end of the adjusting rod 18 is fixedly connected to a handle 19, which allows the operator to manually rotate the adjusting rod 18. The end of the adjusting rod 18 away from the handle 19 is fixedly connected to a blocking plate 20, which prevents the mold 14 from shifting. When the adjusting rod 18 is rotated, the blocking plate 20 can be moved closer to or away from the mold 14, thereby clamping or loosening the mold 14 and meeting the installation, disassembly and fixation requirements of the mold 14. The operation is flexible and convenient.

[0040] Two limiting posts 22 are fixedly connected to the side of the blocking plate 20 near the adjusting rod 18. A spring 23 is sleeved on the outside of the limiting post 22. Two limiting grooves 21 are opened on the front and rear sides of the bottom plate 1. The outside of the limiting post 22 is slidably connected to the inner wall of the limiting groove 21. The limiting groove 21 provides a precise sliding channel for the limiting post 22, which can ensure that the limiting post 22 can slide freely and effectively limit its lateral displacement. One end of the spring 23 is fixedly connected to the outside of the limiting post 22.

[0041] During the installation of mold 14, when the handle 19 is turned to push the adjusting rod 18 to bring the blocking plate 20 closer to mold 14, the limiting post 22 is forced to slide inward along the limiting groove 21, and the spring 23 is compressed. At this time, the spring 23 stores elasticity. When mold 14 needs to be disassembled, the handle 19 is turned in the opposite direction, the spring 23 releases its elasticity, and helps the limiting post 22 slide outward, driving the blocking plate 20 away from mold 14. Throughout the process, the limiting post 22 effectively constrains the movement trajectory of the blocking plate 20, preventing it from deviating or getting stuck. The other end of the spring 23 is fixedly connected to one side of the inner wall of the limiting groove 21. When the blocking plate 20 moves away from mold 14, the spring 23 returns to its original state, helping the limiting post 22 return to its position, ready for the next installation operation of mold 14.

[0042] Working principle: First, place the base plate 1 in a suitable position. Then, put the material into the storage box 7 through the feed inlet. Then, start the motor 8. Driven by the motor 8, the conveyor auger 9 conveys the material and discharges it into the feed hopper 13 through the bottom outlet. Then, start the hydraulic cylinder 11. Driven by the hydraulic cylinder 11, the pressure plate 12 squeezes the concrete downward into the mold 14. Then, start the second motor. Driven by the second motor, the connecting column 2 rotates. As the connecting column 2 rotates, it drives the cam 3 to rotate. As the cam 3 rotates, it drives the connecting plate 4 to shake, which in turn drives the bearing plate 6 to shake. As the bearing plate 6 shakes, it drives the fixing plate 5 to shake, thus making the base plate 1 shake. As the base plate 1 shakes, the mold 14 will flatten the concrete inside, avoiding a large amount of air inside the concrete.

[0043] Then, turn handle 19. When handle 19 is turned, it will drive adjusting rod 18 to move outward. At this time, blocking plate 20 will contact the inner wall of base plate 1 along with adjusting rod 18. At the same time, limiting post 22 will slide against the inner wall of limiting groove 21 under force, so that spring 23 will be compressed under force, thereby allowing mold 14 to be removed. Then, turn rotating rod 15 outward. When rotating rod 15 separates from slot 17, side plate 16 can be removed, thereby removing concrete. Then, side plate 16 is installed on the outside of mold 14. Place mold 14 on top of base plate 1. Turn handle 19. Through adjusting rod 18, push blocking plate 20 away from the inner wall of base plate 1. At the same time, limiting post 22 slides outward from the inner wall of limiting groove 21. Spring 23 is stretched under force, and blocking plate 20 can hold mold 14, preventing it from slipping when base plate 1 shakes.

[0044] 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.
