Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing and production technology, and in particular to a double-sided marking system for refractory bricks that facilitates product quality inspection and traceability. Background Technology

[0002] Currently, refractory bricks account for over 60% of the total output of refractory materials, and come in a wide variety. Due to the influence of different application scenarios and application areas, different types of refractory bricks vary in size and material. If the wrong type is used, it will cause serious quality and safety hazards. Therefore, each brick must be marked with the product model, production date, and production team to facilitate identification and subsequent traceability of quality issues.

[0003] Currently, all manufacturers of refractory bricks use manual marking, which has a low degree of mechanization and is time-consuming and labor-intensive. In addition, when marking manually, only one side of the brick is often marked. When the refractory bricks are stacked on the transfer rack, the marking is easily obscured, making it difficult to distinguish the model of the whole stack of refractory bricks. This greatly increases the labor intensity of workers and the number of operating procedures. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a double-sided marking system for refractory bricks. This system can mark both sides of refractory bricks to facilitate quality traceability and also allows for rapid quality inspection of brick dimensions, thus ensuring the product quality of refractory brick products.

[0005] To achieve the above objectives, the present invention can adopt the following technical solution: The refractory brick double-sided marking system of this utility model includes a frame and a conveyor belt driven by a motor to horizontally transport refractory bricks, which is mounted on the frame. A marking platform is arranged at the end of the conveyor belt. The marking platform is composed of multiple horizontally arranged support rollers, and the axial direction of each support roller is parallel to the width direction of the conveyor belt. Rotating mechanisms are symmetrically arranged on the left and right sides of the marking platform. Marking cylinders are respectively connected to the two rotating mechanisms. The telescopic ends of the marking cylinders are detachably connected to pressure heads for marking on the surface of the refractory bricks. The two marking cylinders are driven to rotate by the rotating mechanisms and have a first working posture with the two telescopic ends facing each other horizontally and a second working posture with the two telescopic ends pointing vertically downward.

[0006] Furthermore, each of the two marking cylinders is provided with an open-top paint box directly below it. The paint box contains high-temperature resistant paint. When the rotating mechanism drives the marking cylinder to maintain the second working posture, the telescopic end of the marking cylinder can extend downwards, so that the pressure head dips into the high-temperature resistant paint in the paint box, thus preventing the paint on the pressure head from drying out and causing the marking to be impossible or unclear.

[0007] Furthermore, a load detection sensor is provided at the front end of the conveyor belt to detect the refractory bricks placed on it. When the load detection sensor detects that refractory bricks are placed on the conveyor belt, the conveyor belt starts to horizontally transport the refractory bricks to the end.

[0008] Furthermore, a position detection sensor is installed between the conveyor belt and the marking platform to detect the passage of the refractory brick. When the position detection sensor detects that the conveyor belt is transporting the refractory brick to the marking platform, the rotating mechanism and the marking cylinder are activated to perform the marking action, and the conveyor belt will also pause transporting the refractory brick.

[0009] Furthermore, a first gantry frame is installed across the middle of the conveyor belt. The first gantry frame is equipped with a size detection sensor for measuring the dimensions of the refractory bricks. The size detection sensor can measure and compare the dimensions of the refractory bricks passing through the first gantry frame to a standard, and will promptly issue an alarm signal to remind the workers if the dimensions of the refractory bricks do not meet the requirements. Additionally, a second gantry frame is installed across the conveyor belt in front of the first gantry frame. The second gantry frame is equipped with a cleaning brush for cleaning the upper surface of the refractory bricks. The cleaning brush can clean the surface of the refractory bricks before the size detection sensor takes measurements, ensuring a clean and tidy surface and guaranteeing the accuracy of subsequent size measurements.

[0010] Furthermore, multiple crossbars for securing the refractory bricks can be arranged at intervals on the outer surface of the conveyor belt. The length direction of the crossbars is consistent with the width direction of the conveyor belt, and a brick-laying groove can be formed between two adjacent crossbars to secure the refractory bricks, thereby improving the stability of the conveyor belt when horizontally conveying the refractory bricks.

[0011] The advantages of this invention are that by using a marking platform arranged at the end of the conveyor belt and marking cylinders symmetrically arranged on the left and right sides of the marking platform and driven by a rotating mechanism, the automatic conveying and double-sided marking of refractory bricks can be easily realized, improving the mechanization and automation of refractory brick marking, reducing the labor intensity of workers, reducing the difficulty and time of operation, and at the same time, it can also prevent the markings from being obscured to the greatest extent, so that at least one side of the markings can be exposed when the refractory bricks are stacked, making it easy to distinguish the model of the whole stack of refractory bricks.

[0014] 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.

[0015] like Figure 1 , 2 As shown, the refractory brick double-sided marking system of this utility model includes a frame 1 and a conveyor belt 2 driven by a motor and mounted on the frame 1. The conveyor belt 2 is horizontally positioned and conveys the refractory bricks 100 placed on it from the front end to the rear end. A marking platform 3 is arranged at the rear end of the conveyor belt 2. The marking platform 3 is composed of multiple horizontally arranged support rollers. All support rollers are fixedly mounted on the frame 1 by a pair of mounting plates, and the axial direction of each support roller is parallel to the width direction of the conveyor belt 2. In addition, rotating mechanisms 4 are symmetrically arranged on the left and right sides of the marking platform 3. The two rotating mechanisms 4 can be fixed to the frame 1 by connecting brackets, or they can be fixed to other equipment around them as needed. Each rotating mechanism 4 has a corresponding marking cylinder 5 connected to its rotating drive end. The telescopic end of the marking cylinder 5 is connected to a pressure head 6 for marking on the surface of the refractory brick 100. The pressure head 6 is detachably connected to the telescopic end of the marking cylinder 5 so as to replace the pressure head 6 with different markings as needed. The two marking cylinders 5 are driven to rotate by the rotating mechanism 4 and have a first working posture with the two telescopic ends facing each other horizontally and a second working posture with the two telescopic ends pointing vertically downward. The first working posture is the marking posture, and the second working posture is the intermittent feeding posture.

[0016] Furthermore, to ensure clear marking with the pressure head 6 each time, a paint box 7 with an open top should be installed directly below each marking cylinder 5. The paint box 7 contains high-temperature resistant paint. When the rotating mechanism 4 drives the marking cylinder 5 to maintain its second working posture, the telescopic end of the marking cylinder 5 can extend downwards, allowing the pressure head 6 to dip into the high-temperature resistant paint in the paint box 7, preventing the paint on the pressure head 6 from drying out and causing marking failure or unclear marking. To improve the stability of the conveyor belt 2 in transporting refractory bricks 100, multiple crossbars 8 for securing refractory bricks 100 can be arranged at intervals on the outer surface of the conveyor belt 2. The length direction of the crossbars 8 is consistent with the width direction of the conveyor belt 2, and the space between two adjacent crossbars 8 can form a brick-laying groove for securing the refractory bricks 100, thus making the refractory bricks 100 more stable.

[0017] Furthermore, to ensure automation, the entire double-sided marking system for refractory bricks should be controlled by a PLC controller. A load detection sensor 9, which can be a piezoelectric sensor, can be installed at the front end of the conveyor belt 2 to detect whether a refractory brick 100 has been placed on the conveyor belt 2. Simultaneously, a position detection sensor 10, which can be a photoelectric sensor, can be installed between the conveyor belt 2 and the marking platform 3 to detect whether a refractory brick 100 has been moved horizontally from the end of the conveyor belt 2 onto the marking platform 3. When the mechanical gripper, working in conjunction with the entire double-sided marking system, picks up a refractory brick 100 that has been pressed in the press and places it onto the conveyor belt 2, the load on the conveyor belt 2 will change. The load detection sensor 9 will then detect this change and transmit the signal to the PLC controller. The PLC controller will then control the conveyor belt 2 to start, horizontally conveying the refractory brick 100 to the end of the conveyor belt 2. When the refractory brick 100 is pushed onto the standardization platform 3 by the conveyor belt 2, the position detection sensor 10 will detect that the refractory brick 100 is in position and transmit the signal to the PLC controller. The PLC controller then controls the conveyor belt 2 to stop and controls the two rotating mechanisms 4 to rotate from the second working posture to the first working posture. Then, it controls the telescopic ends of the two marking cylinders 5 to extend towards each other, thereby realizing double-sided marking of the refractory brick 100 on the standardization platform 3. After the marking is completed, the mechanical gripper can pick up the refractory brick 100 and stack it, which improves the mechanization and automation of the marking of the refractory brick 100, reduces the labor intensity of workers, reduces the difficulty of operation and operation time, and at the same time can prevent the marking from being blocked to the greatest extent, so that at least one side of the marking is exposed when the refractory bricks are stacked, making it easier for workers to distinguish the model of the whole stack of refractory bricks.

[0018] In addition, a first gantry frame 11 can be installed across the middle of the conveyor belt 2, and a size detection sensor 12 can be installed on the first gantry frame 11. The size detection sensor 12 can be a photoelectric distance sensor. The size detection sensor 12 can measure the size of the refractory brick 100 passing through the first gantry frame 11, and then transmit the measured data to the PLC controller. The PLC controller will then compare the data. When the measured size of the refractory brick 100 does not meet the requirements, the entire system can be stopped in time and an alarm signal can be issued to remind the staff. Of course, to ensure the accuracy of dimensional measurement, a second portal frame 13 can be installed across the conveyor belt 2 located in front of the first portal frame 11, and a cleaning brush 14 for cleaning the upper surface of the refractory brick 100 can be installed on the second portal frame 13. When the refractory brick 100 is moved horizontally on the conveyor belt 2, it will first pass through the second portal frame 13. At this time, the cleaning brush 14 can just brush the upper surface of the refractory brick 100, so that the protruding loose feet and attached particles on the surface of the brick are cleaned up, ensuring that the surface of the brick is clean and tidy before passing through the dimensional detection sensor 12, ensuring that the dimensional detection sensor 12 can accurately measure the size of the refractory brick 100.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
