[0038] As Figure 3 With Figure 4 As shown, the lifting trigger mechanism 4 includes a lifting plate 41, two groups of positioning assemblies, a trigger plate 45 and a through slot 46, the positioning assembly includes a positioning push plate 42, a second spring 43 and a passive supporting plate 44, wherein the lifting plate 41 is fixedly sleeved on the outside top of the threaded sleeve 37, the two groups of positioning assemblies are respectively located on the two sides of the inside of the lifting plate 41, the positioning push plate 42 is slidably nested on the top of the lifting plate 41, the second spring 43 is fixedly connected with the inside of the lifting plate 41 and the inner wall of the lifting plate 41, the passive supporting plate 44 is fixedly arranged on the inside top of the positioning push plate 42 and is in contact with the driving push block 36, the trigger plate 45 is fixedly arranged on the outside of the adjacent positioning push plate 42, and the through slot 46 is formed on the top of the trigger plate 45.

[0039] By setting the driving mechanism 3 and the lifting trigger mechanism 4, when the first motor 32 is started, the screw rod 33 drives the threaded sleeve 37 to rise, and the threaded sleeve 37 drives the lifting plate 41 to rise synchronously. In addition, during the rising of the threaded sleeve 37 and the lifting plate 41, the compressed first spring 34 gradually recovers. When the rising distance of the threaded sleeve 37 reaches the first threshold, the top of the lifting plate 41 contacts the refractory brick on the conveying belt 2, and the first spring 34 is completely reset. With the continuous rising of the threaded sleeve 37, the lifting plate 41 lifts the refractory brick.

[0040] When the rising distance of the threaded sleeve 37 reaches the second threshold, the first spring 34 pulls the driving push block 36 through the rotating block 35, thereby removing the blocking of the passive lifting plate 44 by the driving push block 36. At this time, under the pushing of the second spring 43, the two positioning push plates 42 respectively clamp the refractory brick from both sides, thereby completing the positioning of the refractory brick. At this time, the trigger plate 45 also moves synchronously due to the movement of the adjacent positioning push plate 42.

[0041] As shown in Figure 5 The closing mechanism 5 includes a closing cover 51, a friction cavity 52, two avoidance grooves 53, a mounting groove 54, a third spring 55, and a blocking plate 56. The closing cover 51 is fixedly nested on the top of the rack 1. The friction cavity 52 is opened at the bottom of the closing cover 51. The two avoidance grooves 53 are respectively opened at the two sides of the opening at the bottom of the friction cavity 52. The mounting groove 54 is opened at the left side of the bottom of the closing cover 51. The third spring 55 is fixedly connected to the top of the inner side of the mounting groove 54. The blocking plate 56 is slidingly arranged in the inner side of the mounting groove 54 and is fixedly connected with the third spring 55.

[0042] As shown in Figure 5 The adjustable friction mechanism 6 includes a plurality of friction assemblies arranged from left to right. Any one of the friction assemblies includes an adjusting rod 61, a connecting frame 62, a friction roller 63, a fourth spring 64, and an end plate 65. The adjusting rod 61 penetrates through the closing cover 51 and is slidingly connected with the closing cover 51. The connecting frame 62 is fixedly arranged at the bottom end of the adjusting rod 61. The friction roller 63 is rotatably nested in the inner side of the connecting frame 62 through a bearing. A second motor is fixedly arranged at the rear side of the connecting frame 62 and is in transmission connection with the friction roller 63. The fourth spring 64 and the end plate 65 are sequentially sleeved on the outer side of the adjusting rod 61 from bottom to top. The fourth spring 64 is located between the end plate 65 and the closing cover 51. The end plate 65 is fixedly connected with the adjusting rod 61.

[0043] Through the arrangement of the above structure, the second motor at the rear side of the connecting frame 62 can drive the friction roller 63 to continuously rotate, thereby realizing the friction on the refractory brick, and when the refractory brick is an arc-shaped refractory brick, the refractory brick can push the adjusting rod 61 through the friction roller 63, thereby making part of the adjusting rod 61 pull the fourth spring 64 through the end plate 65, so that part of the friction roller 63 rises, thereby enabling more friction rollers 63 to adhere to the surface of the refractory brick, so as to increase the friction detection area and make the detection result more accurate.

[0044] As shown in Figure 5 The dust removal and collection mechanism 7 includes an air pump 71, a shunt pipe 72, a valve 73, an air inlet channel 74, a dust discharge channel 75, a sealing cover 76, a dust filter net 77, and a dust collection cylinder 78. The air pump 71 is fixedly arranged on the top left side of the rack 1. The input end of the shunt pipe 72 is fixedly connected with the output end of the air pump 71. The first output end of the shunt pipe 72 is fixedly connected with the valve 73. The second output end of the shunt pipe 72 is fixedly and penetratingly arranged on the left side of the closed cover 51. The air inlet channel 74 is arranged on the left side of the closed cover 51 and is in communication with the blocking plate 56. The second output end of the shunt pipe 72 is in communication with the air inlet channel 74. The dust discharge channel 75 is fixedly and penetratingly arranged on the right side of the closed cover 51. The sealing cover 76 is fixedly connected with the bottom end of the dust discharge channel 75. The dust filter net 77 is fixedly and nestingly arranged on the front side of the dust discharge channel 75. The dust collection cylinder 78 is placed on the top right side of the bottom plate 31 and is threadedly connected with the sealing cover 76.

[0045] Through the arrangement of the above-mentioned closed mechanism 5 and dust removal and collection mechanism 7, under the normal state, since the air inlet channel 74 is blocked by the blocking plate 56 at this time, the airflow output by the air pump 71 pushes open the valve 73 and is output through the first output end of the shunt pipe 72. When the air inlet channel 74 is unblocked, the airflow output by the air pump 71 enters the inside of the air inlet channel 74 through the second output end of the shunt pipe 72, then passes through the through slot 46 to enter the inside of the friction chamber 52, and drives the dust generated by friction in the inside of the friction chamber 52 to enter the inside of the dust collection cylinder 78 through the dust discharge channel 75. The air passes through the dust filter net 77 and is discharged.

[0046] Embodiment 2

[0047] The application also provides a refractory brick detection method, which is characterized by comprising the following steps:

[0048] S1, start the air pump 71. Since the air inlet channel 74 is blocked by the blocking plate 56 at this time, the airflow output by the air pump 71 pushes open the valve 73 and is output through the first output end of the shunt pipe 72. Then, the refractory brick to be detected is placed on the conveyor belt 2, and the conveyor belt 2 conveys the refractory brick. When the refractory brick moves to the top of the lifting trigger mechanism 4, the first motor 32 is started.

[0049] S2, after the first motor 32 is started, the screw rod 33 drives the threaded sleeve 37 to rise, and the threaded sleeve 37 rises while driving the lifting plate 41 to rise synchronously. In addition, during the rising of the threaded sleeve 37 and the lifting plate 41, the compressed first spring 34 gradually recovers. When the rising distance of the threaded sleeve 37 reaches a first threshold value, the top of the lifting plate 41 contacts the refractory brick on the conveying belt 2, and at the same time, the first spring 34 is completely reset. With the continuous rising of the threaded sleeve 37, the lifting plate 41 lifts the refractory brick;

[0050] S3, when the rising distance of the threaded sleeve 37 reaches a second threshold value, the first spring 34 pulls the driving block 36 through the rotating block 35, and then the driving block 36 removes the blockage of the passive lifting plate 44. At this time, under the pushing of the second spring 43, the two positioning push plates 42 respectively clamp the refractory brick from both sides, thereby completing the positioning of the refractory brick. At this time, the trigger plate 45 also moves synchronously due to the movement of the adjacent positioning push plate 42.

[0051] S4, when the rising distance of the threaded sleeve 37 reaches a third threshold value, the trigger plate 45 enters the inside of the installation groove 54 under the driving of the lifting plate 41 and starts to push the blocking plate 56 upward. When the rising distance of the threaded sleeve 37 reaches a fourth threshold value, the refractory brick enters the inside of the friction chamber 52 under the lifting of the lifting plate 41. Subsequently, with the continuous rising of the lifting plate 41, the refractory brick pushes the plurality of friction rollers 63, thereby causing the adjusting rod 61 to pull the fourth spring 64 through the end plate 65. At this time, the plurality of friction rollers 63 are attached to the top of the refractory brick and are continuously rotated under the driving of the second motor at the rear side of the connecting frame 62, thereby causing the adjusting rod 61 to pull the fourth spring 64 through the end plate 65.

[0052] S5, when the rising distance of the threaded sleeve 37 reaches a fifth threshold value, the top of the lifting plate 41 is attached to the closed cover 51, forming a closed chamber in the friction chamber 52, and the first motor 32 is stopped. At this time, the blocking plate 56 no longer blocks the air inlet channel 74 under the pushing of the trigger plate 45. The airflow output by the air pump 71 enters the inside of the air inlet channel 74 through the second output end of the shunt pipe 72, and then enters the inside of the friction chamber 52 through the through slot 46. The dust generated in the friction chamber 52 by friction enters the inside of the dust collecting cylinder 78 through the dust removal channel 75, and the air is discharged through the dust filter net 77.

[0053] S6, after the friction is completed, the first motor 32 drives the screw rod 33 to rotate in the opposite direction, thereby causing the driving mechanism 3, the lifting trigger mechanism 4, the closing mechanism 5, and the adjusting type friction mechanism 6 to reset in sequence. At this time, the refractory brick after friction falls on the top of the conveying belt 2 and is output by the conveying belt 2. The technician checks the refractory brick after friction, thereby determining whether the refractory brick is qualified. At the same time, the weight change of the dust generated in the friction process can be determined by measuring the weight of the dust collecting cylinder 78, thereby determining whether the refractory brick is qualified.

[0054] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, as long as within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.

7. The refractory brick testing fixture according to claim 6, characterized in that: The air pump (71) is fixedly installed on the top left side of the frame (1). The input end of the diverter pipe (72) is fixedly connected to the output end of the air pump (71). A valve (73) is fixedly connected to the first output end of the diverter pipe (72).

The dust collection cylinder (78) is placed on the top right side of the base plate (31) and threadedly connected to the sealing cover (76).

8. A method for testing refractory bricks according to any one of claims 1-7, characterized in that, Specifically, the following steps are included: S1. Start the air pump (71). Since the air intake channel (74) is blocked by the baffle plate (56) at this time, the airflow output by the air pump (71) breaks through the valve (73) and is output through the first output end of the diverter (72). Then, place the refractory brick to be tested on the conveyor belt (2). The conveyor belt (2) transports the refractory brick. When the refractory brick moves to the top of the lifting trigger mechanism (4), start the first motor (32). S2. After the first motor (32) starts, it drives the threaded sleeve (37) to rise through the screw (33). When the threaded sleeve (37) rises, it drives the lifting plate (41) to rise synchronously. In addition, during the rising process of the threaded sleeve (37) and the lifting plate (41), the compressed first spring (34) gradually recovers. When the rising distance of the threaded sleeve (37) reaches the first threshold, the top of the lifting plate (41) contacts the refractory brick on the conveyor belt (2), and at the same time, the first spring (34) is completely reset. Subsequently, as the threaded sleeve (37) continues to rise, the lifting plate (41) lifts the refractory brick. S3. When the threaded sleeve (37) rises to the second threshold, the first spring (34) pulls the active push block (36) through the rotating block (35), thereby causing the active push block (36) to release the obstruction of the passive support plate (44). At this time, under the push of the second spring (43), the two positioning push plates (42) clamp the refractory brick from both sides, thereby completing the positioning of the refractory brick. At this time, the trigger plate (45) also moves synchronously due to the movement of the adjacent positioning push plate (42). S4. When the threaded sleeve (37) rises to the third threshold, the trigger plate (45) enters the inner side of the mounting groove (54) under the drive of the lifting plate (41) and begins to push the barrier plate (56) upward. When the threaded sleeve (37) rises to the fourth threshold, the refractory brick enters the inner side of the friction chamber (52) under the lifting of the lifting plate (41). Subsequently, as the lifting plate (41) continues to rise, the refractory brick pushes multiple friction rollers (63), thereby causing the adjusting rod (61) to pull the fourth spring (64) through the end plate (65). At this time, multiple friction rollers (63) are attached to the top of the refractory brick and drive the friction rollers (63) to rotate continuously under the drive of the second motor behind the connecting frame (62). S5. When the threaded sleeve (37) rises to the fifth threshold, the top of the lifting plate (41) is in contact with the closed cover (51), so that the friction chamber (52) forms a closed chamber and the first motor (32) is stopped. At this time, the baffle plate (56) no longer blocks the air intake channel (74) under the push of the trigger plate (45). The airflow output by the air pump (71) enters the inside of the air intake channel (74) through the second output end of the split pipe (72), and then passes through the through groove (46) into the inside of the friction chamber (52). This causes the dust generated by friction inside the friction chamber (52) to enter the dust collection cylinder (78) through the dust discharge channel (75). The air is discharged through the dust filter (77). S6. After the friction is completed, the first motor (32) drives the screw (33) to rotate in the opposite direction, thereby causing the drive mechanism (3), the lifting trigger mechanism (4), the sealing mechanism (5) and the adjustable friction mechanism (6) to reset in sequence. At this time, the refractory bricks after friction fall on the top of the conveyor belt (2) and are output by the conveyor belt (2). The technicians can check the refractory bricks after friction to determine whether the refractory bricks are qualified. At the same time, the weight of the dust generated during the friction process can be measured by the weight change of the dust collection cylinder (78) to determine whether the refractory bricks are qualified.
