Description

Technical Field

[0001] This utility model relates to the field of brick production technology, and in particular to a checker brick pressing and leveling device. Background Technology

[0002] As an indispensable key refractory component in industrial kilns, the production process of checker bricks typically involves several crucial steps, including raw material proportioning, mixing, molding, drying, and firing. Among these, the molding step is critical in determining the dimensional accuracy and internal density of the checker bricks, and the brick press is the core equipment in this process. The brick press applies pressure to the brick material loaded into the mold, causing the loose brick material to bind tightly together, forming a checker brick blank with a specific shape and strength.

[0003] As a crucial step before brick pressing, the quality of leveling directly affects the efficiency of the brick press. Traditional leveling methods often use flat-plate leveling devices, which, while ensuring a certain degree of surface flatness, struggle to achieve differentiated control of brick distribution. In some specialized industrial settings, customers have specific requirements for the density distribution of checker bricks: the center density must be lower than the edge density. This density distribution characteristic helps reduce thermal stress concentration during use, as the low-density central area has better thermal expansion buffering capacity, effectively offsetting the stress caused by temperature changes in the high-density edge areas, thus extending the service life of the checker bricks.

[0004] To meet this specific requirement, traditional leveling devices are no longer sufficient. Therefore, it is necessary to develop a checker brick leveling device that can adjust the density of pressed bricks. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art by proposing a checker brick pressing and leveling device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A checker brick pressing and leveling device includes a mounting plate that can be horizontally driven to move. A cylinder is detachably mounted on the mounting plate. A support plate is detachably mounted on the extended end of the cylinder. A geared motor is detachably mounted on the support plate. The extended end of the geared motor passes through the support plate and is detachably mounted on a leveling plate. The leveling plate has a downward convex center.

[0007] Preferably, a cover is detachably installed at the lower end of the tray, and the flat plate is located inside the cover.

[0008] Preferably, the two ends of the flat plate are attached to the inner wall of the cover.

[0009] Preferably, the upper ends of the two edges of the flat plate are chamfered, while the lower ends are not chamfered.

[0010] Preferably, the lower end of the extended end of the geared motor is provided with a through-shaft groove, the lower end of the groove is open, and the flat plate is embedded in the groove and locked by a self-locking bolt.

[0011] Preferably, the mounting plate is symmetrically provided with two sets of sliding rollers on the side away from the reduction motor, and the sliding rollers are horizontally slidably coupled with the slide rail.

[0012] Preferably, the slide rail is C-shaped, and the slide roller is encased inside the slide rail.

[0013] Preferably, the lower end face of the sliding roller is rotatably mounted with a rotating wheel at intervals along the length direction.

[0014] Preferably, the mounting plate is manually driven.

[0015] Preferably, the mounting plate is driven by a telescopic rod.

[0016] Compared with the prior art, this utility model provides a checker brick pressing and leveling device, which has the following beneficial effects: In this invention, the flat material plate has a downward-convex center. This causes the powder in the hopper to form a concave center during material sweeping, resulting in less material in the center. Consequently, during pressing, the density decreases while maintaining the same thickness, creating bricks with lower density in the center and higher density at the periphery, thus meeting the requirements of our product.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-9 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0029] Example 1: To address the problems existing in the prior art, this example provides a checker brick pressing and leveling device, including a mounting plate 4 that can be horizontally driven and moved. A cylinder 5 is detachably mounted on the mounting plate 4 via bolts. The cylinder 5 is a dual-shaft cylinder 5 or a double-group cylinder 5. A support plate 6 is detachably mounted on the extended end of the cylinder 5. External threads are provided on the outer wall of the shaft at the extended end of the cylinder 5, and at least two sets of nuts are screwed onto the external threads at intervals. The support plate 6 has a through hole for the extended end of the cylinder 5 to pass through. At least one set of nuts is provided on both the upper and lower sides of the through hole on the external threads. The support plate 6 is mounted on the telescopic end of the cylinder 5 by the cooperation of the upper and lower nuts. A reduction motor 7 is also detachably mounted on the support plate 6 via bolts. The support plate 6 has a through hole, through which the extended end of the reduction motor 7 passes. A leveling plate 9 is detachably mounted below the through hole at the extended end of the reduction motor 7, and the center of the leveling plate 9 protrudes downwards.

[0030] Based on the above technical solution: Mounting plate 4 can be driven to move horizontally. This feature enables the entire flattening structure to be adjusted horizontally above the hopper, allowing the flattening mechanism to move to the side of the hopper when feeding material, move to the top of the hopper after feeding material for flattening, and move away again before pressing material to avoid interference with pressing material.

[0031] The main function of cylinder 5 is to provide vertical driving force. Through the extension and retraction of its extended end, it drives the pallet 6, the geared motor 7, and the flat plate 9 to move up and down. This design is to prevent the material plate from colliding with the end face of the hopper when it moves horizontally.

[0032] The pallet 6 is made of cast iron and can absorb and attenuate the vibration generated by the geared motor 7 during operation.

[0033] Traditional material slabs, regardless of their structure, mostly have a flat bottom surface. This flat end is used to sweep across the surface of the powder in the hopper, achieving a "smoothing" effect. However, this effect contradicts our product requirements. Our product needs low density at the center and high density at the periphery. Therefore, we designed the flat material slab 9 with a downward-convex center. This way, during sweeping, the powder in the hopper forms a concave center, meaning the amount of powder in the center decreases. Consequently, during pressing, the density decreases while maintaining the same thickness.

[0034] In summary: When the equipment in this solution is in use: During material loading into the hopper, the mounting plate 4 is at the beginning of its stroke, and the flat plate 9 is located on the side of the hopper, not in contact with it. After loading is complete, the mounting plate 4 moves the flat plate 9 directly above the hopper. The cylinder 5 extends, causing the flat plate 9 to move down to the powder surface. The reduction motor 7 then drives the flat plate 9 to rotate, creating a groove on the powder surface through the convex structure at the center of the flat plate 9. After leveling, the cylinder 5 retracts, causing the flat plate 9 to move upwards. The mounting plate 4 then resets, causing the flat plate 9 to be misaligned with the hopper again, at which point pressing begins. Because the powder in the hopper has a groove in the center, when pressed into brick-like blocks (the powder is already agglomerated during the first pressing by the hydraulic press and will not disperse), it forms bricks with a low density in the center and a high density at the periphery, thus meeting the requirements of our desired product.

[0035] In Example 2, to prevent powder from being swept into the hopper from the edge of the flat material plate 9 during the sweeping process, a retaining cover 8 is detachably installed at the lower end of the support plate 6 via bolts, with the flat material plate 9 located inside the retaining cover 8. The upper surface of the retaining cover 8 has a ring array of multiple studs, and the support plate 6 has circular holes corresponding to these studs. Nuts are provided at both the upper and lower ends of the through holes extending from the studs. This allows for detachable installation and adjustment of the gap between the retaining cover 8 and the support plate 6, providing space for the connecting bolts between the geared motor 7 and the support plate 6.

[0036] During the leveling process, the extended end of cylinder 5 drives the support plate 6 to descend, and the cover 8 will be inverted and placed on the end face of the hopper, thereby isolating the powder in the hopper to prevent it from being swept away.

[0037] In Example 3, based on Example 2, the two ends of the flat plate 9 are fitted to the inner wall of the cover 8. This eliminates the gap between the end face of the flat plate 9 and the inner wall of the cover 8, preventing material from accumulating in the gap and causing phased density changes in the finished brick when the flat plate 9 is sweeping.

[0038] In Example 4, the upper ends of the two edges of the flat plate 9 are chamfered, while the lower ends are not. This facilitates the embedding of the flat plate 9 into the cover 8.

[0039] In Example 5, in order to achieve the cooperation between the flat plate 9 and the output end of the geared motor 7, the lower end of the extended end of the geared motor 7 is provided with a slot that passes through the shaft. The lower end of the slot is open, and the flat plate 9 is inserted into the slot and locked by a self-locking bolt, thereby achieving the locking and detachable cooperation between the flat plate 9 and the output shaft of the geared motor 7.

[0040] Two sets of self-locking bolts are spaced apart to prevent the flat plate 9 from deflecting and to make the installation more stable.

[0041] The output end of the geared motor 7 can be connected to a connecting shaft via a coupling, and the slot is set on the connecting shaft. In this way, the slot is machined on the connecting shaft and it is used to cooperate with the flat plate 9. There is no need to change the original structure of the output shaft of the geared motor 7, and it is also convenient to replace it when damaged.

[0042] In Example 6, to achieve horizontal movement of the mounting plate 4, two sets of sliding rollers 2 are symmetrically arranged on the side of the mounting plate 4 away from the reduction motor 7, and are also locked with bolts. The sliding rollers 2 are horizontally slidably fitted with slide rails 1, which are in turn fastened to the table surface of the frame or workbench with countersunk bolts. The cooperation between the sliding rollers 2 and the slide rails 1 provides guidance and support for the horizontal movement of the mounting plate 4. The two sets of sliding rollers 2 and slide rails 1 symmetrically balance the load, which can improve the load-bearing capacity and reduce the probability of deviation during movement.

[0043] The slide rail 1 is C-shaped, with the slide roller 2 encased within it. Compared to a dovetail-groove slide rail 1, this structure is easier to manufacture. Furthermore, the C-shaped design ensures that the upper and lower ends of the slide roller 2 abut against the upper and lower inner walls of the slide rail 1, respectively, thus restricting force on both sides of the slide rail 1 and effectively preventing the slide roller 2 from detaching from it, thereby improving equipment safety. Simultaneously, the C-shaped structure, coupled with a dustproof net, effectively reduces contamination of the mating surfaces of the slide rail 1 and slide roller 2 by external dust and debris, reducing wear and tear on the equipment.

[0044] Preferably, an annular brush can be provided at the port of the slide rail 1 facing the mounting plate 4, so that when the slide roller 2 extends and retracts from the port, it can sweep away the dust adhering to the outside, further reducing dust wear.

[0045] The lower end face of the slide roller 2 has multiple notches spaced along its length. A rotating seat is provided at each notch, and a rotating wheel 3 is rotatably mounted on the rotating seat. The rotating wheel 3 extends out of the notch and abuts against the inner wall of the slide roller 2. The rotating wheel 3 realizes the conversion between sliding friction and rolling friction, which greatly reduces frictional resistance, making the horizontal movement of the mounting plate 4 smoother and less strenuous, and reducing the difficulty of the drive device. At the same time, rolling friction can also reduce the wear between the slide roller 2 and the slide rail 1, extending the service life of the equipment.

[0046] Preferably, rollers 3 are provided at both the upper and lower ends of the sliding roller 2 for smoother sliding.

[0047] Preferably, when the mounting plate 4 moves to the end of the stroke, i.e. the material sweeping position, at least two sets of rollers 3 at both the upper and lower ends of the sliding roller 2 are still inside the slide rail 1. Alternatively, the bracket is symmetrically provided with two sets of brackets around the hopper, which allows the slide rail 1 to be extended, thus preventing the sliding roller 2 from being suspended in the air and making the movement more stable.

[0048] In Example 7, the mounting plate 4 moves horizontally through the cooperation of the sliding roller 2 and the slide rail 1. The driving method can be divided into two types: The first method is manual drive: workers wearing gloves hold the side of the mounting plate 4, or pull it by a handle on the side of the mounting plate 4, which controls the horizontal movement of the mounting plate 4. Although the sliding roller 2 moves within the slide rail 1, it has a starting end based on its length, i.e., a stroke locking point (the C-shaped slide rail 1 in the attached diagram is shown in an open state, but in actual use, in addition to setting a dust removal screen, the rear end is sealed, and the front end is equipped with a baffle, and the side wall of the sliding roller 2 is equipped with a stop block that cooperates with the baffle to limit the stroke and prevent the sliding roller 2 from slipping directly). At the beginning of the stroke, it is fine as long as it remains stationary; however, at the end of the stroke, i.e., when it needs to be aligned with the hopper, it must remain stable while the geared motor 7 and other equipment are running. At this time, a limiting device can be added, such as fixing an iron plate on the stop block on the sliding roller 2, and a magnet that cooperates with the iron plate on the baffle at the end of the stroke. The magnetic attraction between the magnet and the iron plate keeps the sliding roller 2 stable. Preferably, an electromagnet can be added for stronger magnetic attraction.

[0049] The second type is automatic drive: a telescopic rod is fixedly added to the mounting platform of the slide rail 1. The telescopic rod can be any one of a hydraulic rod, pneumatic rod, or electric telescopic rod, and the extended end of the telescopic rod is fixedly connected to the rear end face of the mounting plate 4. Through a preset stroke, the telescopic rod can drive the mounting plate 4 to move horizontally when it extends, and it is more stable.

[0050] In this design, all bolts, studs, and nuts are threaded and self-locking, meaning self-locking nuts and bolts are used to prevent stripping due to vibration. Alternatively, holes can be drilled at the bolt ends to install cotter pins for mechanical locking.
