DETAILED DESCRIPTION

[0023] Figures 1 to 4 It is the best embodiment of the utility model, and the following Figures 1 to 4 The utility model is further described.

[0024] like Figure 1 As shown, the utility model is a kiln production auxiliary destacking device, including a support frame 9, a column 12 and a fixing clamp 10. The column 12 is vertically and fixedly arranged on the support frame 9, the fixing clamp 10 is vertically slidably arranged on the column 12, and the fixing clamp 10 is connected with a lifting power part. The fixing clamp 10 includes two symmetrically arranged clamping arms 15 and two clamping claws 25. The two clamping arms 15 are slidably arranged on the column 12, and the two clamping claws 25 are respectively connected to the front ends of the clamping arms 15 through a pushing device. The pushing device pushes the clamping claws 25 forward so that the two clamping claws 25 are close to each other and clamp the conveyed material to fix it.

[0025] like Figure 2~3 As shown, in this embodiment, the conveyed material is a crucible 3, and four crucibles 3 are stacked into a group and conveyed to the device on the conveying roller 5 for destacking. The above-mentioned support frame 9, column 12 and fixing clamp 10 are fixing mechanism 1, and fixing mechanism 1 is arranged on one side of the conveying roller 5. The crucible 3 is conveyed to the fixing mechanism 1, and the staff or robot needs to disassemble the stacked crucible group one by one. However, since the crucible group has been fired in the kiln, there may be adhesion between the crucibles and they cannot be easily separated. Therefore, the fixing mechanism 1 is required to fix them, and then the crucibles 3 are separated one by one. Specifically, the pushing device drives the fixing clamp 10 to first clamp the second crucible 3 from top to bottom, so that the top crucible 3 is taken away, and then the lifting power part drives the fixing clamp 10 to move downward, and then clamps the second crucible 3 from top to bottom at this time, and the staff or robot takes away the top crucible 3 at this time, and repeats the above process to separate each crucible 3.

[0026] The conveying roller 5 is arranged on the fixed frame 6, and the conveying roller motor 7 drives the conveying roller 5 to rotate so as to convey the crucible 3. In the present embodiment, a tray 4 is arranged under each group of crucibles 3, and the fired crucible 3 is conveyed to the device. Each fixing clamp 10 of the fixing mechanism 1 is connected to the lifting block 16 through the clamping arm 15, and two relatively arranged fixing clamps 10 are connected to a lifting block 16. A slide rail 24 is arranged on the column 12, and the lifting block 16 can be slidably installed on the slide rail 24 of the column 12. The lifting block 16 is connected to the lifting motor 14, and a screw assembly is arranged between the lifting motor 14 and the lifting block 16. The output end of the lifting motor 14 is connected to the nut of the screw assembly, and the nut is threadedly connected to the screw. The lifting block 16 is fixedly connected to the screw, and the lifting motor 14 drives the nut to rotate and drives the screw to make a linear motion in the vertical direction, thereby driving the lifting block 16 to move up and down. Support plates 23 are also provided on both sides of the lifting motor 14 . The support plates 23 are fixedly connected to the columns 12 . The support plates 23 can play a role in strengthening the strength of the columns 12 .

[0027] The pushing device in this embodiment is a clamping cylinder 11, which is fixedly connected to the front end of the clamping arm 15, and the fixing clamp 10 is installed at the output end of the clamping cylinder 11. The fixing clamp 11 includes a connecting plate and clamping blocks arranged on both sides of the connecting plate. The clamping blocks are in the shape of a right triangle, and the hypotenuses of the two clamping blocks are arranged oppositely. When the stacked crucibles 3 are transported to the fixing mechanism 1, the lifting motor 14 lifts the fixing clamp 10 to a suitable position, and the two clamping cylinders 11 arranged oppositely push the two fixing clamps 10 to clamp the crucible 3. A drag chain 13 is also arranged on one side of the column 12, which is suitable for use in reciprocating motion occasions and can play a pulling and protective role for the built-in cables, etc.

[0028] The clamping position of the fixing clamp 10 is fixed. If the position of the crucible 3 is not in the middle of the fixing clamp 10 during transportation, the fixing clamp 10 will be off-center when clamping and fixing, and may even damage the surface of the crucible 3. Therefore, before the crucible 3 is transported to the fixing mechanism 1, it needs to be centered to ensure that the crucible 3 is exactly in the middle of the fixing clamp 10 when it is transported to the fixing mechanism 1. Therefore, a centering mechanism 2 is provided on one side of the fixing mechanism 1 close to the starting end of the conveying roller 3.

[0029] like Figure 4As shown, the centering mechanism 2 includes a centering jaw 19 symmetrically arranged on both sides of the conveying roller 5, the centering jaw 19 is connected to a telescopic power member, the centering mechanism 2 is fixedly mounted on the fixed frame 6 of the conveying roller 5 through a mounting block 17, and the telescopic power member in this embodiment is a centering cylinder 18, which is mounted on the fixed frame 6 on both sides of the conveying roller 5 through the mounting block 17, and the centering cylinders 18 on both sides simultaneously drive the two centering jaws 19 to move forward so that they clamp and fix the crucible 3. The centering jaw 19 also includes a connecting plate and clamping blocks arranged on both sides of the connecting plate, the clamping blocks are in the shape of a right triangle, and the hypotenuses of the two clamping blocks are arranged oppositely. A buffer roller 20 is arranged on the front side of the centering jaw 19, and the buffer roller 20 is vertically and rotatably connected to the centering jaw 19. Since the centering jaw 19 is fixed during the conveying process of the crucible 3, the buffer roller 20 can reduce the damage of the centering jaw 19 to the crucible 3.

[0030] Specifically, the centering jaw 19 includes a connecting plate 1901 and two clamping blocks 1902 symmetrically arranged on the connecting plate 1901. The two clamping blocks 1902 are respectively arranged near the two sides of the connecting plate 1901, and the sides where the two clamping blocks 1902 are close to each other are inclined. The clamping blocks 1902 are in the shape of a right triangle, and the hypotenuses of the two clamping blocks 1902 are arranged opposite to each other. Buffer rollers 20 are rotatably arranged at the ends of the two clamping blocks 1902. The rotatably arranged buffer rollers 20 can provide a rotational buffer margin when the centering jaw 19 contacts the crucible 3, thereby avoiding damage to the surface of the crucible 3 when the centering jaw 19 centers the crucible 3.

[0031] During the centering process, the conveying roller 3 is also continuing to convey the crucible 3, and it is necessary to prevent the crucible 3 from being further conveyed. Therefore, a fixed column 21 is also provided on one side of the centering clamp 19, and the fixed column 21 fixes the tray 4 to prevent the tray 4 from being further conveyed. A fixed column 21 is provided on one side of at least one centering clamp 19, and the fixed column 21 is vertically provided. The fixed column 21 is connected to a lifting power component. In this embodiment, the lifting power component is a fixed cylinder 22, and fixed columns 21 are provided on both sides of the conveying roller 5. The fixed cylinder 22 drives the fixed column 21 to press down and fix the tray 4. After the last group of crucibles 3 is destackered, the centering clamp 19 and the fixed column 21 release the crucible group, so that it continues to be conveyed to the fixing mechanism 1.

[0032] A limit column 8 is arranged between the fixing mechanism 1 and the conveying rollers 5 corresponding to the centering mechanism 2. The limit column 8 is connected with a lifting power part. In this embodiment, the lifting power part is a cylinder. The cylinder drives the limit column 8 to rise. The limit column 8 rises from between the conveying rollers 5 and is higher than the upper surface of the conveying roller 5. The limit column 8 blocks the front of the tray 4 of the crucible group, preventing it from moving forward.

[0033] When the utility model is in use, the conveying roller 5 conveys the crucible group to the centering mechanism 2, the fixed cylinder 22 drives the fixed column 21 to press down and fix the tray 4, and the two centering cylinders 18 simultaneously drive the two centering claws 19 to move forward to clamp and fix the crucible 3. After the crucible 3 is centered, the centering claws 19 release the crucible 3, and the tray fixing column 21 moves up to release the tray 4, so that it continues to be conveyed to the fixing mechanism 1. The fixing clamp 10 first clamps the second crucible 3, and the staff or robot clamps the top crucible 3 away, and then the lifting motor 14 drives the fixing clamp 10 to move down, and the fixing clamp 10 clamps the next crucible 3, and the staff or robot clamps the top crucible 3 at this time, repeating the above process, and the four crucibles 3 are separated and taken away by the staff or the robot. The utility model automation equipment reduces the repetitive labor that workers need to perform, reduces the labor intensity, improves the production enthusiasm and work efficiency of workers, and reduces the safety risks caused by manual operation.

[0034] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
