The block breaking device 100 is a special device for breaking the blocks of the materials in the saggar 200 burnt in the kiln, and in popular terms, the powdered materials such as graphite powder and the like in the saggar 200 are easy to agglomerate in the burning process and are not beneficial to the automatic production of the subsequent production process, so that the agglomerated materials can be broken by the block breaking device 100 to be reduced into powder, and the automatic production is facilitated.

As shown in fig. 1, the chunking apparatus 100 includes a sagger conveyor 20, a sagger elevating device 30 located below the sagger conveyor 20, and a material chunking device 10 located above the sagger conveyor 20 and disposed corresponding to the sagger elevating device 30.

The sagger 200 burned in the kiln is horizontally conveyed by the sagger conveying device 20 to be conveyed to a material processing station corresponding to the material block breaking device 10, and then the sagger 200 is lifted to a preset height by the sagger lifting device 30 to be close to the material block breaking device 10, so that the block breaking processing operation is performed, and the materials agglomerated in the sagger 200 are reduced into powder. In the chunking apparatus 100, after the chunking process is completed, the chunking lift 30 lowers and transfers the chunking lift to the sagger conveyor 20, and the sagger conveyor 20 performs a further horizontal conveying operation, such as conveying to a next station.

In the above-described structure, the sagger transfer device 20 is formed with a hollow area 20a corresponding to the material block processing station for passing through the sagger lift device 30 to lift or lower the sagger 200.

The aforementioned sagger elevating device 30 is disposed corresponding to the hollow area 20a, and when the sagger 200 is located at the fragment processing station corresponding to the hollow area 20a, the sagger elevating device 30 can penetrate and extend from the hollow area 20a and support the sagger 200 to rise to a certain height, that is, the sagger 200 is elevated to a predetermined height position and separated from the sagger conveying device 20. Like this, on the one hand be convenient for broken piece device 10 of material to carry out the broken piece processing to sagger 200, on the other hand, can protect sagger conveyor 20 is whole, avoid broken piece device 10 of material to carry out the thrust of broken piece and cause the damage to sagger conveyor 20, simultaneously, also can protect sagger 200 self, the surface contact of sagger elevating gear 30 and the bottom of sagger 200 compares in the point contact between sagger 200 and first conveying roller 111 or second conveying roller 121, realizes the protection to sagger 200.

Moreover, the aerial area 20a is also beneficial to accurately positioning the sagger 200 in the conveying process, and the sagger 200 is ensured to be positioned on a material block breaking processing station. In addition, the sagger conveying device 20 can efficiently and quickly convey the sagger 200.

As shown in fig. 2 to 4, the sagger transporting device 20 includes: conveying part 1, installation part 2, material stopping part 3 and guide part 4.

As shown in fig. 4, the conveying unit 1 includes: two first conveyor units 11 and two second conveyor units 12.

The two first conveying units 11 are disposed along the preset conveying direction of the sagger 200 at a predetermined interval, and the two second conveying units 12 are interposed between the two first units and disposed opposite to each other, and the conveying directions of the two first conveying units 11 and the two second conveying units 12 are kept in agreement, thereby conveying the sagger 200 along the preset conveying direction. A hollow area 20a corresponding to the chipping processing station is formed between the two first conveying units 11 and the two second conveying units 12.

As shown in fig. 3 and 4, the mounting portion 2 serves as a main body carrying portion of the entire sagger conveyor 20 for mounting and fixing the two first conveying units 11 and the two second conveying units 12 and the material blocking portion 3 and the guide portion 4. Specifically, the mounting portion 2 includes two first longitudinal plates 21 disposed at intervals at a predetermined interval, a transverse plate 22 fixedly connected between the two first longitudinal plates 21, and second longitudinal plates 23 respectively fixedly disposed adjacent to the first longitudinal plates 21. Next, a flat plate 22 is fixed between the two fixed side plates 21. In addition, the mounting portion 2 further includes two second longitudinal plates 23 fixed at positions respectively adjacent to the longitudinal plates 21.

The first conveying unit 11 includes a plurality of first conveying rollers 111, and the plurality of first conveying rollers 111 are sequentially disposed on the left and right sides of the broken block processing station along the conveying direction. In particular, as shown in fig. 2 and 4, the first transport units 11 each only show a partial schematic view next to the left and right of the chipping processing station, i.e. the two first transport units each include two first transport rollers 111.

The second conveying unit 12 includes a plurality of second conveying rollers 121, and the plurality of second conveying rollers 121 are disposed at upper and lower sides corresponding to the chipping processing stations. Specifically, as shown in fig. 2 and 4, the second conveying unit 12 includes three second conveying rollers 121 disposed on the upper and lower sides of the chipping processing station, respectively.

In the solution of the present embodiment, generally, the fragment processing station is located at the central position of the fragment device 100, so the two conveying units 11 have the same structure and function, and only the arrangement positions are different; of course, there may be differences in the position of the chipping processing station in the chipping device 100, such as an off-center position, which results in different lengths of the first conveying units 11 on both sides of the chipping processing station, i.e., different numbers of the first conveying rollers 111, and the others remain the same. In addition, the two second conveyance units 12 are also identical in structure and function and are different only in the arrangement position, and therefore, only one of the first conveyance roller 111 and the second conveyance roller 121 will be described in detail here, and detailed description of the other identical first conveyance roller 111 and second conveyance roller 121 will be omitted.

In addition, the length of the second conveyor roller 121 is smaller than the length of the first conveyor roller 111, so that a hollow area 20a corresponding to the chipping process station is formed between the first conveyor roller 111 and the second conveyor roller 121 disposed adjacent to the chipping process station. Preferably, the length of the second conveying roller 121 is less than half of the length of the first conveying roller 111.

In addition, the size of the hollow region 20a matches the size of the bottom of the sagger 200, specifically, the size of the bottom of the sagger 200 in the conveying direction is taken as the length, and the size in the direction perpendicular to the conveying direction is taken as the width, and based on this, at least the width value of the bottom size of the sagger 200 is larger than the corresponding width of the hollow region 20a, so that when the sagger 200 is at the position of the hollow region 20a, the bottom surface of the sagger 200 is at least contacted with the second ceramic wheel 121b, and the sagger 200 can be supported.

In other words, the size of the hollow area 20a is smaller than the size of the bottom of the sagger 200 to ensure that the hollow area 20a has a predetermined area, thereby facilitating the elevating movement of the sagger elevating unit 30. And sufficient contact area can be ensured between the sagger lifting device 30 and the bottom of the sagger 200, so that the sagger 200 is supported and protected in the material block breaking process, specifically, damage to the first conveying roller 111 and/or the second conveying roller 121 due to the pushing force of the material block breaking device 10 caused by the fact that the sagger 200 is placed on the second conveying roller 121 and/or the first conveying roller 111 to directly perform the block breaking process is avoided, and surface contact is formed between the sagger lifting device 30 and the bottom of the sagger 200, so that the protection of the sagger 200 is realized compared with point contact between the sagger 200 and the first conveying roller 111 and/or the second conveying roller 121.

The first conveying roller 111 includes: a first roller shaft 111a, two first ceramic wheels 111b, and two elastic members 111 c.

The length of the first roller shaft 111a matches the interval between the two first longitudinal plates 21 of the mounting part 2, thereby ensuring that both ends of the first roller shaft 111a are rotatably fixed to the two first longitudinal plates 21. The two first ceramic wheels 111b are sleeved on the first roller shaft 111a at a preset interval, the two elastic pieces 111c are respectively clamped between the two first ceramic wheels 111b and the end portions of the corresponding first roller shafts 111a, and in a normal conveying state, the two elastic pieces 111c are in a compression state, so that the corresponding first ceramic wheels 111b are pushed to drive the first ceramic wheels 111b to synchronously rotate along with the first roller shafts 111 a.

The second conveying roller 121 includes: a second roller 121a, a second ceramic wheel 121b, and an elastic member 121 c.

The second roller shaft 121a is rotatably fixed on the first longitudinal plate 21 of the mounting portion 2 through a bearing seat, the second ceramic wheel 121b is sleeved on the second roller shaft 121a and is flush with the corresponding first ceramic wheel 111b on the first roller shaft 111a, the elastic member 121c is clamped between the second ceramic wheel 121b and the end portion of the second roller shaft 121a, and in a normal conveying state, the elastic member 121c is also in a compression state, so that the corresponding second ceramic wheel 121b is pushed against and driven to drive the second ceramic wheel 121b to synchronously rotate along with the second roller shaft 121 a.

All of the first conveying roller 111 and the second conveying roller 121 are driven to rotate by a driving mechanism not shown in the figure, thereby conveying the sagger 200 thereon.

The material blocking part 3 is arranged at a position close to the broken block processing station and used for blocking the conveyed sagger 200 to stop conveying and just on the broken block processing station. Specifically, the material blocking portion 3 includes a material blocking cylinder 31 and a baffle 32.

The material blocking cylinder 31 is fixed on the transverse plate 22 of the mounting part 2, and the position of the transverse plate 22 does not interfere with the lifting movement of the sagger lifting device 30 and is used for providing power to drive the baffle 32 to move in a stretching and contracting manner.

The baffle 32 is fixed at the piston rod of the material blocking cylinder 31 and the extending ends of the two guide rods, and in the initial state, the material blocking cylinder 31 is positioned below the first conveying roller 111, and the top of the baffle 32 is not higher than the horizontal plane of the first conveying roller 111, so that the conveying of the sagger 200 is prevented from being interfered. When the sagger 200 is conveyed to a position close to the material block breaking processing station, the baffle 32 is lifted by the power provided by the material blocking cylinder 31 and then contacts the side wall of the sagger 200 so as to block the sagger 200, so that the sagger 200 stops conveying and stays on the block breaking processing station.

When the material blocking portion 3 blocks the sagger 200, the friction force between the sagger 200 and the second ceramic wheel 121b is increased, so that the second ceramic wheel 121b overcomes the pushing force applied by the corresponding second elastic member 121c, and the second roller 121a idles in the second ceramic wheel 121b, thereby preventing the sagger 200 from being damaged or worn due to the friction generated between the synchronous rotation of the second ceramic wheel 121b and the bottom of the sagger 200. Similarly, if the bottom of the sagger 200 is in contact with the first ceramic wheel 111b, the friction between the sagger 200 and the first ceramic wheel 111b is increased, so that the first ceramic wheel 111b overcomes the pushing force of the first elastic member 111c to rotate the first roller shaft 111a in the first ceramic wheel 111b, thereby preventing the first ceramic wheel 111b from rubbing the sagger 200 to damage or wear the sagger 200.

The two guide portions 4 are respectively provided on upper and lower sides of the conveying direction along the conveying direction, and are used for positioning and guiding the sagger 200 in the conveying process of the sagger 200.

In the present embodiment, the two guide portions 4 have the same structure and function, and are disposed at different positions, and only one of the guide portions 4 will be described in detail, and the detailed description of the other guide portion 4 will be omitted.

As shown in fig. 3 to 5, the guide portion 4 includes: a cylinder 41 and a guide 42. Fig. 5 is a schematic structural view of the guide portion 4 located above in fig. 4.

The cylinder 41 is disposed at a corresponding position on one side of the sagger 200, and is fixed to the second longitudinal plate 23 of the mounting part 2, for providing power to the guide 42 to position the guide 42 at a predetermined distance on one side of the sagger 200.

The guide 42 is for guiding the sagger 200 during the transportation, and the guide 42 includes: a cross bar 421 fixedly connected with the piston rod 411 and the two guide rods 412 of the cylinder 41, two guide posts 422 fixed at both ends of the cross bar 421, and two elastic sleeves 423 respectively arranged at the ends of the guide posts 422 facing the sagger 200.

Based on the structure of the guide part 4, the transverse plate 421 and the two guide posts 422 are driven to synchronously move by the telescopic movement of the piston rod 411 driven by the cylinder 41, so that the elastic sleeve 423 at the end part of the guide posts 422 keeps a preset distance with the sagger 200. As shown in fig. 3 and 5, in the present embodiment, the two guiding portions 4 are designed to face away from each other by the guide rod cylinders 41, so that when the sagger 200 is inclined and deviated during transportation, the sagger 200 is guided and positioned by the pushing action of the four elastic sleeves 423 on both sides on the sagger 200, so that the sagger 200 is kept stable during transportation. Here, the elastic member 423 is made of an elastic material, such as a polyurethane material, so as to ensure that the elastic member 423 is in soft contact when providing a resisting force to the sagger 200 during the guiding and positioning processes, thereby preventing the sagger 200 from being damaged or worn by rigid contact.

Based on the above structure, the sagger conveying device 20 performs the sagger conveying process as follows:

the first roller shaft 111a and the second roller shaft 121a are driven to rotate by the driving mechanism, and the first ceramic wheel 111b and the second ceramic wheel 121b synchronously rotate due to the abutting action of the first elastic piece 111c and the second elastic piece 121c, so that the sagger 200 is conveyed onto the first ceramic wheel 111b from one end, and the conveying of the sagger 200 is gradually realized. The material blocking cylinder 31 drives the baffle 32 to extend to a height position higher than the first conveying roller 111, when the sagger 200 is conveyed to be blocked by the baffle 32, the conveying is stopped, at this time, the friction force between the sagger 200 and the second ceramic wheel 121b is increased, so that the second ceramic wheel 121b overcomes the pushing force of the corresponding second elastic piece 121c and does not rotate, and the second roller shaft 121a is kept idle in the second ceramic wheel 121 b. Next, the sagger elevating device 30 elevates the sagger 200 to a height close to the material crushing device 10 so as to be separated from the sagger conveying device 20, and the material crushing operation is performed; after the block breaking operation is completed, the sagger 200 is lowered by the sagger lifting device 30, so that the sagger 200 is supported on the sagger conveying device 20 again. Then, the material blocking cylinder 31 drives the blocking plate 32 to retract, so that the sagger 200 is continuously conveyed along the conveying direction.

Through above sagger transportation process, guarantee that the sagger after the kiln is fired can be carried to the broken piece fast on handling the station by the high efficiency, be convenient for carry out the broken piece processing operation of material safely moreover, avoid causing the damage to sagger conveyor, greatly promoted sagger conveying efficiency and whole production efficiency.

Secondly, in above-mentioned structure, the second conveying roller is for adopting the broken axle design in comparison with first conveying roller, breaks the original whole root axle back, has formed the lift space that sagger lifting device corresponds, makes things convenient for jacking and descending, furthest increases jacking area and the area of contact to the bearing of sagger.

Thirdly, first conveying roller and second conveying roller adopt long-pending formula roller of putting, and elastic design, after the casket-like bowl was kept off the material portion and is blockked, the idle rotation of roller has avoided the friction between ceramic wheel and the casket-like bowl to produce the foreign matter, and the ceramic wheel adopts spring, lock ring, friction disc design, and the adjustment is convenient, even also can adjust at work.

Finally, the two guide parts are designed in a back-to-back mode through the air cylinder with the guide rod, the distance can be conveniently adjusted according to the size of the sagger, and the sagger deviation caused by the fact that the air cylinders are asynchronous is avoided.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims.
