Description

Technical Field

[0001] This invention relates to the field of lightweight building material processing technology, specifically to a quality testing device for finished lightweight building materials. Background Technology

[0002] Lightweight building materials mainly include: lightweight bricks, environmentally friendly lightweight concrete blocks, high-performance lightweight aggregate concrete, lightweight partition boards, and lightweight wall panel materials. In the production process of lightweight building materials, pressure testing machines are often used to test the load-bearing capacity of these materials to determine the quality of the finished product. However, current testing machines for lightweight building materials have the following drawbacks: 1. They require manual handling of the blocks onto the testing table, resulting in high labor intensity and low automation due to the weight of the blocks; 2. Waste material may splash during testing, leading to low safety performance of the machine. To address these issues, Chinese Utility Model Patent (Authorization Announcement No.: CN 211453151 U, Authorization Announcement Date: 2020.09.08) discloses a pressure testing machine for blocks. This machine uses a feeding device to transport the blocks to the testing table, reducing the operator's labor intensity, and incorporates safety devices to enhance safety.

[0003] However, in practical operation, the feeding device can only lift the blocks, but cannot accurately push them to the center of the test bench. Manual intervention is still required (e.g., rollers driven by a conveyor motor transport the blocks to the test bench, and the operator pushes the blocks directly under the test bench for testing). While this solution improves feeding efficiency to some extent, it cannot achieve accurate, fully automated feeding, and the level of automation needs further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a quality testing device for lightweight building materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A lightweight building material finished product quality testing device includes a base frame and further includes: a pressure testing machine, installed and fixed in the middle of the base frame, for performing pressure tests on the lightweight building material finished product; a feeding conveying device, installed and fixed in the front end of the base frame, for conveying the lightweight building material finished product to the base platform of the pressure testing machine; a discharging conveying device, installed and fixed in the rear end of the base frame, for discharging the lightweight building material finished product; and a pushing mechanism, installed and fixed in the front end of the base frame, the driving end of the pushing mechanism having a vertical push plate one and a vertical push plate two, the vertical push plate one being used to push the lightweight building material finished product at the end of the feeding conveying device to the base platform of the pressure testing machine, and the vertical push plate two being used to push the lightweight building material finished product on the base platform to the discharging conveying device.

[0007] The horizontally moving vertical pusher plate one can push the finished lightweight building material from the end of the feeding conveyor to the base platform of the pressure testing machine, so that the pressure testing machine can perform pressure testing on it. At the same time, the horizontally moving vertical pusher plate two can push the finished lightweight building material from the base platform to the discharge conveyor, through which the finished lightweight building material can be discharged.

[0008] Preferably, the pushing mechanism includes a pushing machine base plate, a lifting and telescopic element, a pushing telescopic element, and a pushing base plate. The pushing machine base plate is fixedly installed on the base frame by the surrounding columns. The lifting and telescopic element is fixedly installed on the pushing machine base plate. The telescopic end of the lifting and telescopic element is fixedly installed with a pushing frame plate. The pushing frame plate is fixedly installed with horizontally arranged pushing telescopic elements.

[0009] The pusher base plate is slidably fitted on the lower end face of the pusher frame plate, and an upper seat plate is fixedly connected to the pusher base plate. The upper seat plate is fixedly connected to the telescopic end of the pusher telescopic element.

[0010] The first vertical pusher plate and the second vertical pusher plate are fixedly connected to the lower end face of the pusher base plate.

[0011] Preferably, the pusher plate is also provided with a plurality of lifting guide rods, the upper ends of which are movably mounted on the pusher base plate.

[0012] Preferably, the pressure testing machine includes a pressure telescopic element, a support column, and a base platform fixed on the base frame. The base platform is fixedly mounted with a top base via the support column. The pressure telescopic element is fixedly mounted on the top base. The pressure telescopic element is mounted with a pressure seat for applying pressure to the finished lightweight building material via a ball joint.

[0013] Preferably, the feeding conveying device and the discharging conveying device adopt the same conveying mechanism. The conveying mechanism includes a conveyor frame that is fixed on the base frame. Multiple conveying rollers are rotatably mounted on the conveyor frame. A conveying motor for driving the conveying rollers to rotate is also installed on the side wall of the conveyor frame.

[0014] Preferably, it also includes a centering and positioning mechanism, which includes a centering telescopic element and a push plate. The centering telescopic element is fixedly installed on the side of the conveyor frame of the feeding conveyor via a centering base. The telescopic end of the centering telescopic element is fixedly installed with a centering push plate for pressing the side wall of the finished lightweight building material. With the cooperation of the centering and positioning mechanism, it can be ensured that the finished lightweight building material can be pushed directly under the pressure seat of the pressure testing machine.

[0015] Preferably, the device also includes a limiting and stopping mechanism, which comprises a limiting telescopic element and an L-shaped limiting baffle for stopping the finished lightweight building material. The limiting telescopic element is fixedly installed at the lower end of the conveyor frame of the feeding conveyor via a limiting base. One end of the L-shaped limiting baffle is fixedly connected to the telescopic end of the limiting telescopic element, and the other end of the L-shaped limiting baffle extends through the gap between the two conveying rollers. The L-shaped limiting baffle of the limiting and stopping mechanism can stop the finished lightweight building material and position it in the forward direction.

[0016] Preferably, the vertical section of the L-shaped limiting baffle is further provided with a set of vertical guide grooves, and a vertical guide strip is fixedly installed on the side wall of the limiting base near the vertical section of the L-shaped limiting baffle. The vertical guide strip is slidably connected to the vertical guide grooves. This ensures the structural stability of the L-shaped limiting baffle and ensures a good limiting effect.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The pusher mechanism of the present invention has a vertical pusher plate 1 and a vertical pusher plate 2. By driving the vertical pusher plate 1 and the vertical pusher plate 2 to move horizontally in sync, the horizontally moving vertical pusher plate 1 can push the finished lightweight building material at the end of the feeding conveyor to the base platform of the pressure testing machine, so that the pressure testing machine can perform pressure testing on it. At the same time, the horizontally moving vertical pusher plate 2 can push the finished lightweight building material on the base platform to the discharge conveyor, and the finished lightweight building material can be exported through the discharge conveyor.

[0018] Through the cooperation of the limiting and blocking mechanism, the centering and positioning mechanism and the feeding and conveying device, the pushing mechanism can accurately complete the above-mentioned pushing operation, ensuring that the finished lightweight building material to be tested can be accurately pushed onto the base platform of the pressure testing machine, and the finished lightweight building material after the test can be pushed out.

[0019] Compared with existing technologies, the entire testing process of this invention requires virtually no human intervention, has a higher degree of automation, and makes pressure testing operations more convenient. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] For ease of explanation, in this embodiment, the finished lightweight building material can specifically be a lightweight building block 200. Of course, in other embodiments, the finished lightweight building material can also be a lightweight partition board, lightweight brick, lightweight aggregate concrete, etc. The solution of the present invention is equally applicable, only the size ratio of each component of the present invention needs to be adjusted.

[0031] Please see Figures 1-8 A lightweight building material finished product quality testing device includes a base frame 100. The invention also includes a pressure testing machine 2, which is installed and fixed in the middle of the base frame 100 and is used to perform pressure tests on the lightweight building blocks 200.

[0032] The feeding conveyor 1 is installed and fixed at the front end of the base frame 100 and is used to convey lightweight building blocks 200 to the base platform 21 of the pressure testing machine 2.

[0033] The discharge conveyor 3 is installed and fixed at the rear end of the base frame 100 and is used to discharge the lightweight building blocks 200.

[0034] The pushing mechanism 4 is installed and fixed at the front end of the base frame 100. The driving end of the pushing mechanism 4 has a vertical push plate 431 and a vertical push plate 432. The vertical push plate 431 is used to push the lightweight building block 200 at the end of the feeding conveying device 1 to the base platform 21 of the pressure testing machine 2. The vertical push plate 432 is used to push the lightweight building block 200 on the base platform 21 to the discharge conveying device 3.

[0035] The pushing mechanism 4 of this invention has a vertical push plate 431 and a vertical push plate 432 at its driving end. By driving the vertical push plate 431 and the vertical push plate 432 to move horizontally in sync, the horizontally moving vertical push plate 431 can push the lightweight building block 200 at the end of the feeding conveying device 1 onto the base platform 21 of the pressure testing machine 2, so that the pressure testing machine 2 can perform pressure testing on it. At the same time, the horizontally moving vertical push plate 432 can simultaneously push the lightweight building block 200 on the base platform 21 onto the discharge conveying device 3, through which the lightweight building block 200 can be discharged. Compared with the prior art, the entire testing process of this invention basically requires no manual intervention, has a higher degree of automation, and the pressure testing operation is more convenient.

[0036] As a specific solution, the pushing mechanism 4 includes a pushing machine base plate 41, a lifting telescopic element 42, a pushing telescopic element 45, and a pushing base plate 43. The pushing machine base plate 41 is fixedly installed on the base frame 100 by the surrounding columns. The lifting telescopic element 42 is fixedly installed on the pushing machine base plate 41. The telescopic end of the lifting telescopic element 42 is fixedly installed on the pushing frame plate 44. The pushing telescopic element 45 is fixedly installed on the pushing frame plate 44.

[0037] The pusher base plate 43 is slidably fitted on the lower end face of the pusher frame plate 44, and an upper seat plate is fixedly connected to the pusher base plate 43. The upper seat plate is fixedly connected to the telescopic end of the pusher telescopic element 45.

[0038] The vertical push plate 431 and the vertical push plate 432 are fixedly connected to the lower end face of the push plate 43.

[0039] To ensure the smooth lifting of the pusher plate 44, multiple lifting guide rods 46 are also fixedly distributed on the pusher plate 44, and the upper ends of the lifting guide rods 46 are movably inserted into the pusher base plate 41.

[0040] The working principle of the pushing mechanism 4 is as follows: when it is necessary to push the lightweight building block 200, the lifting telescopic element 42 drives the pushing frame plate 44 and the pushing telescopic element 45 to descend. Then, the pushing telescopic element 45 drives the pushing base plate 43 to move horizontally. The vertical pushing plate 1 431 can push the lightweight building block 200 at the end of the feeding conveying device 1 onto the base platform 21 of the pressure testing machine 2. At the same time, the vertical pushing plate 2 432 pushes the lightweight building block 200 on the base platform 21 onto the discharge conveying device 3.

[0041] After the material is pushed, the lifting telescopic element 42 and the pushing telescopic element 45 are reset to prevent the vertical push plate 1 431 and the vertical push plate 2 432 from affecting the subsequent feeding of lightweight building blocks 200.

[0042] Specifically, the pressure testing machine 2 includes a pressure telescopic element 22, a support column 24, and a base platform 21 fixed on the base frame 100. The base platform 21 is fixedly mounted with a top base 25 via the support column 24. The pressure telescopic element 22 is fixedly mounted on the top base 25. The pressure telescopic element 22 is mounted with a pressure seat 23 for applying pressure to the lightweight building block 200 via a ball joint.

[0043] The working principle of the pressure testing machine 2 is as follows: the pressure telescopic element 22 is activated, and the pressure telescopic element 22 drives the pressure seat 23, so that the pressure seat 23 contacts the lightweight building block 200. Then, a pressure load is applied to the lightweight building block 200 uniformly at a speed of 2.0±0.3kN / s until the lightweight building block 200 is destroyed. The destruction pressure load can be recorded to verify whether the quality of the lightweight building block 200 is qualified.

[0044] As a specific embodiment, the feeding conveyor 1 and the discharging conveyor 3 adopt the same conveying mechanism, which includes a conveyor frame 11 fixed on the base frame 100. Multiple conveying rollers 12 are rotatably mounted on the conveyor frame 11, and a conveying motor for driving the conveying rollers 12 to rotate is also installed on the side wall of the conveyor frame 11. By driving the conveying rollers 12 to rotate via the conveying motor, the rotating conveying rollers 12 can move the lightweight building blocks 200. To ensure better conveying effect, a conveyor belt can also be fitted onto the conveying rollers 12 in this embodiment.

[0045] The present invention also includes a limiting and blocking mechanism, which includes a limiting telescopic element 13 and an L-shaped limiting baffle 14 for blocking the lightweight building blocks 200. The limiting telescopic element 13 is fixedly installed at the lower end of the conveyor frame 11 of the feeding and conveying device 1 through a limiting base. One end of the L-shaped limiting baffle 14 is fixedly connected to the telescopic end of the limiting telescopic element 13, and the other end of the L-shaped limiting baffle 14 passes through the gap between the two conveying rollers 12.

[0046] The working principle of the limiting and blocking mechanism is as follows: When the lightweight building block 200 is transported on the feeding conveyor 1, the limiting telescopic element 13 remains in a retracted state. At this time, the L-shaped limiting baffle 14 can block the lightweight building block 200 and position the lightweight building block 200 in the forward direction. After the positioning is completed, the conveying motor of the feeding conveyor 1 stops running. Then, the limiting telescopic element 13 extends and drives the L-shaped limiting baffle 14 to descend, releasing the limiting of the lightweight building block 200. Subsequently, the lightweight building block 200 can be pushed from the feeding conveyor 1 to the base platform 21 of the pressure testing machine 2 by the pushing mechanism 4.

[0047] Furthermore, in order to ensure the structural stability of the L-shaped limiting baffle 14, a set of vertical guide grooves 141 are also provided on the vertical section of the L-shaped limiting baffle 14. A vertical guide strip is also fixedly installed on the side wall of the limiting base near the vertical section of the L-shaped limiting baffle 14. The vertical guide strip is slidably connected to the vertical guide grooves 141.

[0048] As a further solution, in order to ensure that the lightweight building block 200 can be pushed directly under the pressure seat 23 of the pressure testing machine 2, the present invention also includes a centering positioning mechanism 5. The centering positioning mechanism 5 includes a centering telescopic element 51 and a push plate 52. The centering telescopic element 51 is fixedly installed on the side of the conveyor frame 11 of the feeding conveying device 1 through a centering base. The telescopic end of the centering telescopic element 51 is fixedly installed with a centering push plate 52 for pushing the side wall of the lightweight building block 200.

[0049] The working principle of the centering and positioning mechanism 5 is as follows: when the lightweight building block 200 is positioned by the limiting and blocking mechanism, the conveying motor of the feeding conveying device 1 stops running, and the centering telescopic elements 51 on both sides drive the push plate 52 to push the lightweight building block 200 so that the lightweight building block 200 is in the middle position. Then, the limiting telescopic element 13 extends to release the limiting of the lightweight building block 200.

[0050] The working principle of this invention is as follows: First, the lightweight building block 200 is transported by the feeding conveyor 1. When the lightweight building block 200 is transported on the feeding conveyor 1, the limiting telescopic element 13 remains in a contracted state. At this time, the L-shaped limiting baffle 14 can block the lightweight building block 200 and position the lightweight building block 200 in the forward direction.

[0051] After positioning is completed, the conveying motor of the feeding conveyor 1 stops running, the centering positioning mechanism 5 works, and the centering telescopic element 51 drives the push plate 52 to push the lightweight building block 200 so that the lightweight building block 200 is in the middle position.

[0052] Then, the limiting telescopic element 13 extends, releasing the restriction on the lightweight building block 200;

[0053] Next, the pushing mechanism 4 operates, driving the vertical push plate 1 431 and the vertical push plate 2 432 to move horizontally in sync. The horizontally moving vertical push plate 1 431 can push the lightweight building block 200 at the end of the feeding conveying device 1 onto the base platform 21 of the pressure testing machine 2, so that the pressure testing machine 2 can perform pressure testing on it. At the same time, the horizontally moving vertical push plate 2 432 can push the lightweight building block 200 on the base platform 21 to the discharge conveying device 3, through which the lightweight building block 200 can be discharged.
