Description

Technical Field

[0001] The invention relates to the technical field of special-shaped refractory materials, in particular to an automatic forming machine for special-shaped refractory materials. Background Art

[0002] Refractory bricks are called fire bricks for short. They are refractory materials with certain shapes and sizes. According to the preparation process, refractory bricks can be divided into fired bricks, unfired bricks, fused bricks (fused cast bricks), and refractory insulation bricks; according to the shape and size, they can be divided into standard bricks, ordinary bricks, special bricks, etc. They can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures.

[0003] Patent document CN201310419007.2 discloses a refractory brick forming mold and a brick forming method thereof. The mold cavity is rectangular, and the upper and lower forming surfaces of the formed brick product have no positive or negative tolerances. Therefore, triangular seams can be eliminated during the masonry process, thereby increasing the service life of the masonry. In addition, the friction between the brick product and the cavity template is eliminated, forming a frictionless separation between the brick product and the cavity template, effectively protecting the cavity template and increasing the frequency of reuse; the cavity template can be adjusted and formed multiple times according to the thickness of the support plate. After the friction generated between the cover plate and the mold cavity causes local damage to the mold cavity, the thickness of the support plate is reduced and then the mold is formed.

[0071] The processing mechanism 3 includes a material discharge mechanism 4, a compaction mechanism 5 and a material discharge mechanism 6 which are sequentially arranged along the transmission direction of the transmission assembly 1, wherein the material discharge mechanism 4 and the compaction mechanism 5 are located above the mold assembly 2 and the material discharge mechanism 6 is located below the mold assembly 2;

[0072] The mold assembly 2 includes a frame assembly 21 adapted to the side of the refractory brick 100 , a plurality of groups of module assemblies 22 mounted on the frame assembly 21 , and a support assembly 23 disposed below the frame assembly 21 .

[0073] In this embodiment, a feeding mechanism 4 is provided to cooperate with the mold assembly 2. When the raw material accumulates from bottom to top in the mold assembly 2, the barrier portion corresponding to the irregular vacant portion of the refractory brick 100 extends out to prevent the raw material from moving to the irregular vacant portion of the refractory brick. At the same time, the mold assembly 2 can be quickly disassembled after molding, which is convenient for the automatic output of the refractory bricks, and the mold assembly 2 can be quickly assembled after the output, thereby improving the stability of the overall operation of the equipment and thereby improving the working efficiency of the equipment.

[0074] Secondly, according to the sequence of refractory brick forming processes, this equipment sequentially arranges the unloading process, the compacting process and the output process. Each functional structure is reasonably arranged in accordance with the sequence of processes, and the functional areas are clearly divided, each performing its own function, thereby improving work efficiency.

[0075] Further, if Figures 4 to 8 As shown, the frame assembly 21 includes a base 211 installed on the transmission assembly 1, a bottom frame 212 fixedly installed on the base 211, and four groups of template units 213 distributed in a rectangular structure, and the template units 213 include two groups of long plates 214 arranged opposite to each other and two groups of short plates 215 arranged opposite to each other and located between the two groups of long plates 214;

[0076] Any group of the long plates 214 and the short plates 215 are driven to reciprocate by a driving member 216, and the driving member 216 includes a support 2161 installed on the base frame 212, a screw rod 2162 rotating on the support 2161, and a slider 2163 threadedly connected to the screw rod 2162 and connected to the template unit 213, the slider 2163 is slidably arranged in a guide groove 2164 opened in the base frame 212, the adjacent ends of the two groups of the screw rods 2162 are connected by bevel gears 2165, and the other end of the screw rod 2162 located on one side of the long plate 214 is connected to a driving wheel 2166.

[0077] Further, if Figure 6As shown, a first active rack 41 meshing with the active wheel 2166 is arranged in front of the unloading mechanism 4, and a second active rack 42 meshing with the active wheel 2166 and arranged opposite to the teeth of the first active rack 41 is arranged behind the compacting mechanism 5.

[0078] In this embodiment, by arranging the frame assembly 21 to cooperate with the first active rack 41, the frame assembly 21 is automatically retracted and tightly connected under the drive of the first active rack 41 before it is transmitted into the unloading mechanism 4, thereby avoiding leakage of raw materials during unloading and improving the molding quality; at the same time, by cooperating with the second active rack 42, the frame assembly 21 is automatically unfolded and the pressure is released after the refractory bricks are formed, thereby facilitating the automatic output of the formed refractory bricks and improving the degree of automation of production.

[0079] It should be noted that self-locking is achieved through screw transmission, the mechanical transmission efficiency is high, maintenance is convenient, and the front and rear work are easy to control.

[0080] In detail, when the driving wheel 2166 is transmitted to the first driving rack 41, the driving wheel 2166 rotates, the screw rod 2162 is driven, and the long plate 214 slides toward the long plate 214 on the opposite side through the slider 2163 limited in the guide groove 2164. At the same time, the rotating screw rod 2162 drives the screw rod on one side of the short plate 215 on the other side to synchronously drive through the bevel gear 2165, and the short plate 215 slides toward the short plate 215 on the opposite side through the slider 2163 limited in the guide groove 2164, thereby realizing that the long plate 214 and the short plate 215 on the side form a closed rectangular structure, which is conducive to the unloading of raw materials;

[0081] On the contrary, when the driving wheel 2166 is transmitted to the second driving rack 42, the driving wheel 2166 rotates in the opposite direction, the screw rod 2162 is transmitted, and the long plate 214 slides toward the long plate 214 on the opposite side through the slider 2163 limited in the guide groove 2164. At the same time, the rotating screw rod 2162 drives the screw rod on one side of the short plate 215 on the other side to transmit synchronously through the bevel gear 2165 again, and the short plate 215 slides toward the short plate 215 on the opposite side through the slider 2163 limited in the guide groove 2164, thereby realizing that the long plate 214 and the short plate 215 on the side form a non-closed rectangular structure, completing the pressure relief, which is beneficial to the output of the formed refractory bricks.

[0082] Further, if Fig.11 and Fig.12 As shown, the module assembly 22 includes:

[0083] A driving shaft 221, wherein the driving shaft 221 is installed on the template unit 213 via a connecting spring 222;

[0084] A transmission shaft 223, wherein the transmission shaft 223 is elastically mounted inside the driving shaft 221;

[0085] Magnet a225, the magnet a225 is arranged on the outer shaft of the driving shaft 221 and attracts the magnet b on the corresponding template unit 213, and the magnet b is an electromagnet;

[0086] The push rod 226 is arranged at the outer end of the driving shaft 221 and is a spherical structure.

[0087] It should be noted that the connecting spring 222 supports the driving shaft 221. In addition, a rubber ring 224 is provided at the connection between the transmission shaft 223 and the long plate (or short plate) to seal the driving shaft 221 and prevent the infiltration of raw materials. At the same time, the rubber ring 224 is made of elastic material. When the press 51 is pressed, the transmission shaft 223 can be pressed down to keep the stamping margin floating, thereby ensuring that the refractory bricks are stamped densely in place.

[0088] Further, if Fig.12 , Fig.13 As shown, the module assembly 22 is driven by the first drive assembly 24 and the second drive assembly 25 to reciprocate;

[0089] The first driving assembly 24 includes a first driving unit 26 installed on the first telescopic unit 423 and synchronously driven with the first filling assembly 42, and a second driving unit 27 installed on the second telescopic unit 433 and synchronously driven with the second filling assembly 43, and the first driving unit 26 and the second driving unit 27 both include a first wedge block 262 intermittently contacting the push rod 226;

[0090] The second driving assembly 25 includes a transmission frame 251 that is synchronously driven with the first pneumatic unit 411 and a second wedge block 252 disposed at the telescopic end of the transmission frame 251 .

[0091] In this embodiment, by arranging the module assembly 22 to cooperate with the first driving assembly 24, when the first filling assembly 42 is unloaded to a specific position, the first filling assembly 42 drives the module assembly 22 to extend into the frame assembly 21 through the first driving assembly 24, and fills the special-shaped part of the refractory brick, ensuring that the height of the raw material filling is lower than the height of the transmission shaft 223 extending therein, so that the transmission shaft 223 is inserted horizontally and fully extended to the bottom without being blocked by the accumulation of raw materials, thereby improving the quality of refractory brick forming;

[0092] In addition, the module assembly 22 is used in conjunction with the second drive assembly 25, and the second drive assembly 25 uses the first drive assembly 24 to synchronously complete the resetting of the module assembly 22 and the avoidance of the refractory brick discharge, thereby realizing the rapid disassembly and assembly between the module assembly 22 and the frame assembly 21; on the other hand, the same driving force is used to complete the two tasks simultaneously, saving additional power output and reducing production costs.

[0093] In detail, the first driving unit 26 moves downward and drives the first wedge block 262 to act on the outer end of one group of push rods 226. The push rods 226 drive the driving shaft 221 to extend into the frame assembly 21, and the magnet a225 moves to the magnet b. The two attract each other. At this time, one end of the transmission shaft 223 completes entering the frame assembly 21 and abuts against the inner wall of the plate. After the raw material is filled, the second driving unit 27 moves downward and drives the first wedge block 262 of the group to act on the outer end of another corresponding push rod 226. The push rods 226 drive the driving shaft 221 to extend into the frame assembly 21, and the magnet a225 moves to the magnet b. One end of the transmission shaft 223 of the group completes entering the frame assembly 21 and abuts against the inner wall of the plate, completing the limit and preventing the raw material from penetrating into this position; under the attraction of the magnet, the two or more groups of module assemblies 22 are firmly positioned in the frame assembly 21 to achieve positioning, which is conducive to the final forming of the refractory bricks;

[0094] After the refractory bricks are formed and move to the bottom of the second driving assembly 25, the transmission frame 251 drives the second wedge block 252 to move downward, and the second wedge block 252 acts on the end of the push rod 226, and the magnet a225 is separated from the magnet b under the action of external force.

[0095] It should be noted that the inclined cutouts of the first wedge block 262 and the second wedge block 252 are arranged in opposite directions.

[0096] Further, if Fig.16 and Fig.17 As shown, an oscillating member 227 is disposed in the transmission shaft 223, and the oscillating member 227 includes:

[0097] A rotating rod 2271, the inner end of which is rotatably disposed in a limiting ring 2273 of the transmission shaft 223 via a spring a2272; and the outer end of which is matched and transmitted in an arc groove 2274 of the driving shaft 221;

[0098] knocking rods 2275, wherein the knocking rods 2275 are arranged in a plurality of groups along the length direction of the rotating rod 2271;

[0099] A trigger block a2276, wherein the trigger block a2276 is disposed at the outer end of the rotating rod 2271;

[0100] The linkage member 2277 includes a one-way rack 2278 installed on the unloading mechanism 4, a meshing wheel 2279 installed on the bottom frame 212 and meshing with the one-way rack 2278, and a cam 2270 that is synchronously transmitted with the meshing wheel 2279 and drives the trigger block a2276 to transmit regularly.

[0101] In this embodiment, by setting the unloading mechanism 4 in conjunction with the oscillating member 227, the raw materials are synchronously and fully oscillated during the process of filling the module assembly 22, thereby improving the fluidity of the raw materials, increasing the density of the brick-making raw materials, and improving the quality of the products.

[0102] In detail, when the first filling assembly 42 is reset, the one-way rack 2278 is lifted up with the first telescopic unit 423, the one-way rack 2278 drives the meshing wheel 2279 to rotate, the meshing wheel 2279 drives the cam 2270 to transmit synchronously, the cam 2270 drives the touch block a2276 to transmit regularly, the rotating rod 2271 reciprocates in the limit ring 2273, the knocking rod 2275 knocks the inner wall of the transmission shaft 223 with a frequency to complete the vibration of the transmission shaft 223, thereby realizing the orderly filling of the raw materials on the outside of the transmission shaft 223, and the touch block a2276 is set to an elastic rubber material;

[0103] In addition, the working principle of the second filler assembly 43 is the same as that of the first filler assembly 42, which will not be described in detail here.

[0104] It should be noted that, according to actual working conditions, an opening may be opened on the bottom frame 212, and the one-way rack may move downward and extend into the opening and then extend downward.

[0105] Further, if Figures 18 to 23 As shown, the feeding mechanism 4 comprises:

[0106] A starting component 41, the starting component 41 comprises a first pneumatic unit 411, a mounting frame 412 arranged at the output end of the first pneumatic unit 411, and a material storage box 413 mounted on the mounting frame 412, a material discharge port 414 is arranged at the lower end of the material storage box 413, and the material discharge port 414 is controlled by a valve to start and stop operation;

[0107] A first filling assembly 42, the first filling assembly 42 comprises a second pneumatic unit 421, a first material baffle plate 422 arranged at an output end of the second pneumatic unit 421 through a first telescopic unit 423 and matching and sliding on the material storage box 413, a limit block a424 installed on the first telescopic unit 423, and a limit block b425 installed on the mounting frame 412 and intermittently abutting against the limit block a424; and

[0108] A second filling assembly 43, the second filling assembly 43 comprises a third pneumatic unit 431, a second material baffle plate 432 arranged at the output end of the third pneumatic unit 431 through a second telescopic unit 433 and matching and sliding on the material storage box, a limit block c434 installed on the second telescopic unit 433, and a limit block d435 installed on the mounting frame 412 and intermittently abutting against the limit block c434;

[0109] A third baffle plate 44 is also provided at the connection between the first baffle plate 422 and the second baffle plate 432 and both are hollow plate structures. The upper ends of the first baffle plate 422 and the second baffle plate 432 are intermittently connected and engaged with the third baffle plate 44 through a rubber clamping block 45.

[0110] In this embodiment, a feeding mechanism 4 is provided to cooperate with the module assembly 22. When the raw material is filled to a certain height not higher than the lower end after the bottom transmission shaft is inserted, the first baffle plate 422 moves down to the upper surface of the raw material in the frame assembly, and then the raw material output from the discharge port 414 is output to one side of the first baffle plate 422 to prevent the raw material from falling to the other side of the first baffle plate 422. The module assembly is then put in place by utilizing the descending first wedge block 262. When the first baffle plate 422 is reset, the lower end of the raw material therein loses the limit and automatically feeds to one side of the module assembly. The oscillating member 227 has a regular amplitude through the transmission shaft 223, so that the raw material on the edge is fully infiltrated, thereby ensuring the molding quality of special-shaped refractory bricks while improving production efficiency.

[0111] In detail, when the frame assembly moves to the bottom of the unloading mechanism 4, the first pneumatic unit 411 is started, the material storage box 413 is lowered to the upper end of the frame assembly, the valve opens the discharge port 414, and the raw material is output from the material storage box 413 to the support plate. When the raw material is output to a certain amount, the second pneumatic unit 421 is started, and the first baffle plate 422 is lowered to the upper surface of the raw material. At this time, the limit block a424 moves to the limit block b425, the first baffle plate 422 is no longer moving, the first telescopic unit 423 continues to move downward, and the first wedge block 262 Acting on the outer end of the corresponding push rod 226, the module assembly 22 extends into the frame assembly 21, and then the first pneumatic unit 411 starts to reset, and the first material baffle plate 422 is lifted up, and the raw material in the first material baffle plate 422 is output to one side of the transmission shaft, and the raw material fully fills the bottom end of the transmission shaft under the vibration of the transmission shaft. At the same time, the discharge port 414 continues to discharge the material. After the raw material rises to a certain height, the third pneumatic unit 431 starts, and the working principle of the second filling assembly 43 is the same as that of the first filling assembly 42, which will not be repeated here.

[0112] In addition, through the shared third baffle plate 44, both the horizontal first baffle plate 422 and the vertical second baffle plate 432 can drive the third baffle plate 44 to automatically fill when they descend to complete the filling work, and at the same time, the rubber clamping block 45 with sufficient friction is used to complete the clamping synchronization work; on the other hand, it is also easy to automatically disengage from another set of output clamping blocks 45 when moving downward, and its structure is simple and ingenious.

[0113] It should be noted that the time and stroke of the second pneumatic unit 421 and the third pneumatic unit 431 are set, and they are opened and closed regularly; that is, when the discharge port 414 outputs a certain value of a certain quantity of raw materials, the second pneumatic unit 421 is started, and when the raw materials are higher than the module assembly 22 at the bottom, the second pneumatic unit 421 is reset, and when the discharge port 414 outputs a certain value of a certain quantity of raw materials again, the third pneumatic unit 431 is started, and when the raw materials are higher than the module assembly 22 at the high end, the third pneumatic unit 431 is reset.

[0114] It is worth mentioning that when the first baffle plate 422 moves downward, the raw materials in the storage box 413 automatically enter the upper end of the first baffle plate 422 and are stored inside the first baffle plate 422. When the first baffle plate 422 is lifted up, the raw materials inside the first baffle plate 422 are automatically output downward; the second baffle plate 432 has the same working principle as the first baffle plate 422, which will not be repeated here.

[0115] Further, if Figure 1 and Fig. 9 As shown, the compacting mechanism 5 includes a press and a first platform unit located below the press 51 and used for supporting the seat 233 .

[0116] In detail, under the action of the press, the press 51 acts on the raw material, and the raw material is extruded and formed; at the same time, the first platform unit completes the support work of the support seat 233. The first platform unit is controlled by a distance sensor. When the press 51 is started, the two groups of platform steel plates move in the same direction and combine to complete the support of the support seat 233. It is only necessary to open a position on it to avoid the connection between the bottom frame and the base.

[0117] It should be noted that the transmission component 1 is started intermittently, and the dwell time each time is consistent, which can be set in advance according to the actual working conditions.

[0131] Working process:

[0132] Step 1: The mold assembly 2 is driven by the transmission assembly 1 to be transmitted backward in sequence;

[0133] Step 2: The frame assembly 21 moves to the unloading mechanism 4, and the unloading mechanism completes the unloading work;

[0134] Step 3: The frame assembly 21 drives the filled raw material to move to the compacting mechanism 5 to complete the molding;
