Description

Technical Field

[0001] This invention relates to the field of lightweight brick processing technology, specifically to a molding and cutting device for processing ultra-lightweight, high-strength mullite-corundum lightweight bricks. Background Technology

[0002] The production process of lightweight bricks includes: feeding, mixing, pouring, foaming, demolding, cutting, stacking, curing and leaving the factory. After the formed green body has been initially cured and solidified to reach the cutting strength, it can be demolded and cut. A large green body is conveyed to the cutting equipment for longitudinal and transverse cutting to cut into the corresponding specifications.

[0003] According to patent CN219634096U, an aerated concrete block cutting device is used to adjust the required cutting angle by setting a rotating component, and then directly process and treat the bricks. Based on the cooperation of the thrust bearing, the fixed plate and the rotating plate, the rotating plate rotates on the fixed plate, so that the bricks can be rotated for cutting and trimming.

[0004] However, in the actual operation of the above-mentioned patent, since the brick blank is transmitted to the longitudinal groove after being cut in the transverse groove, and the brick blank needs to be continuously transmitted and cut, the brick blank itself is not limited. As a result, in the subsequent turning transmission process, it is easy to force several blank strips to disperse or deviate from the running track, which affects the effect of longitudinally cutting the blank strips into blocks and causes the specifications of the cut bricks to be inconsistent, thus reducing the efficiency of lightweight bricks.

[0005] To address this technical deficiency, a solution is proposed. Summary of the Invention

[0006] The purpose of this invention is to improve the efficiency of lightweight brick cutting by setting up a top frame, a platform, a positioning component and a cutting mechanism in combination, and to perform horizontal and vertical equidistant cutting on the brick blank after clamping and positioning the whole brick blank, while simultaneously grinding the cut surfaces. This not only improves the efficiency of lightweight brick cutting, but also ensures the quality of the cut bricks.

[0007] The objective of this invention can be achieved through the following technical solution: a molding and cutting device for processing ultra-lightweight and high-strength mullite corundum lightweight bricks, comprising a concave operating frame, a square platform, and a top frame. The bottom of the platform is movably connected to the center of the inner wall of the bottom of the operating frame via a pivot. The top frame is movably disposed on the top surface of the operating frame and located above the platform. Uprights are fixedly installed at four corners of the top of the top frame, and inserts are fixedly installed at corresponding positions on the inner wall of the top of the operating frame and the four uprights. The four uprights are respectively inserted into the corresponding inserts, and spring coils are wound around the sections of the outer wall of the uprights inside the inserts. A positioning component is provided on one side of the platform.

[0008] The positioning component includes a cylinder, which is located on the inner wall of the operating frame away from the opening. A push rod is attached to one end of the cylinder. A concave abutment frame is fixedly installed at the end of the push rod away from the cylinder. Abutment pieces are movably connected to the front and rear inner walls of the concave abutment frame. The two sets of abutment pieces are arranged with their opposite sides and the ends near the opening of the concave abutment frame are beveled. Long rods are fixedly installed on both sides of the two sets of abutment pieces away from each other. One end of the long rod passes through and extends to the outside of the concave abutment frame. A spring coil is arranged on the outside of the long rod between the abutment piece and the inner wall of the concave abutment frame. A vertical plate is fixedly installed on the top surface of the concave abutment frame on one side of the front and rear frame. A round shaft is fixedly installed at the top of the opposite sides of the two sets of vertical plates.

[0009] Furthermore, the front half of the top frame is open, and the front and rear ends of the top frame are provided with a sloping groove on one side, and both ends of the sloping groove are provided with horizontal grooves. The two sets of circular shafts are slidably connected inside the horizontal grooves near the bottom.

[0010] Furthermore, the front and rear inner walls of the top frame are provided with movable grooves at the ends away from the openings. A sliding plate is connected between the two sets of movable grooves, and a cylinder is provided between the sliding plate and the inner wall of one side of the top frame through a push rod. An L-shaped fixing frame with three-quarters of its own length is provided on the side of the sliding plate away from the cylinder.

[0011] Furthermore, the sliding plate and the L-shaped fixing frame are both provided with sliding grooves. A cutting mechanism is provided between the two sets of sliding grooves at the rear end. A crossbar is fixedly installed at the rear end of the inner wall of the top frame near the opening, and a round shaft is fixedly installed at one end of the bottom surface of the crossbar.

[0012] Furthermore, the cutting mechanism includes a first horizontal frame and a second horizontal frame. The first horizontal frame and the second horizontal frame are distributed front to back and slidably connected inside the first sliding groove. The first horizontal frame and the second horizontal frame are fixedly connected at both ends by connecting rods. A pusher is fixedly installed at the tail end of the second horizontal frame away from the first horizontal frame, and several sets of inclined grooves are evenly arranged on the top surface of the pusher. A straight groove is provided on the surface of the pusher between the beginning and end of two adjacent sets of inclined grooves.

[0013] Furthermore, both the first and second horizontal frames are provided with rectangular inner grooves near one end, and a dual-axis motor is provided between the first and second horizontal frames near one end. The front and rear bearings of the dual-axis motor extend into the corresponding rectangular inner grooves and are respectively fixedly installed with a toothed disc and a turntable, and the bottom of the toothed disc extends to the outside of the rectangular inner groove.

[0014] Furthermore, a circular block is fixedly installed at one end of the center of the side of the turntable away from the sawtooth disk. The circular block is slidably connected to a vertical frame. The upper and lower ends of the vertical frame extend to the outside of the rectangular inner groove, and the bottom of the vertical frame is provided with a conical rough surface. A movable shaft is fixedly installed at the center of the side of the vertical frame away from the circular block, and the movable shaft is slidably connected to the inside of the second sliding groove opened on the inner wall of the corresponding rectangular inner groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention involves setting up a platform, a top frame, and a positioning component. The brick blank is placed on the platform, and a cylinder is activated to move the concave abutment frame toward the brick blank. Two sets of elastic abutment plates are used to adaptively clamp and position the brick blank to reduce the deviation of the blank body and affect the directional and equidistant cutting effect. At the same time, two sets of vertical plates move with the concave abutment frame, and the first round shaft moves from the inside of the horizontal groove to the inside of the inclined groove, forcing the top frame and its internal cutting components to be close to the surface of the brick blank, so as to facilitate the subsequent directional cutting of the brick blank and improve the brick blank cutting efficiency.

[0017] 2. The present invention also includes a cutting mechanism that works in conjunction with the internal structure of the top frame. A cylinder drives the cutting mechanism to move back and forth. The saw toothed disc is located at the starting end on the side of the blank. A dual-axis motor drives the saw toothed disc to rotate and first cut the blank laterally. The saw toothed disc moves to the other end of the blank. Then, a cylinder drives the saw toothed disc to reset and move again, passing through the cutting line to make additional cuts to the blank, so as to avoid some blanks sticking together during the initial cutting.

[0018] When the horizontal frame is reset and moved, the push bar and the horizontal bar move relative to each other, and force the second round shaft to slide into the corresponding inclined groove, forcing the push bar, the first horizontal frame and the second horizontal frame to move in an orientation. The saw toothed disc then moves sequentially and equidistantly to the next cutting point on the side of the blank. The above steps are repeated, and so on, to cut into several blanks at equal intervals. This structure not only facilitates equidistant positioning and cutting to avoid the blanks being cut into different sizes, but also speeds up the cutting efficiency of the blanks, reducing the situation of partial sticking of the blanks due to insufficient cutting, and further improving the efficiency of lightweight brick forming and cutting.

[0019] 3. The present invention also sets up a turntable, a circular block and a vertical frame, etc. The dual-axis motor drives the saw tooth disk and causes the turntable to rotate. The bottom end of the vertical frame is aligned with the side of the cutting line. During this process, the turntable moves synchronously with the horizontal frame and rubs and scrapes the side wall of the brick to speed up the removal of impurities on the cutting surface. At the same time, the rotation of the turntable pulls the vertical frame to move back and forth, thereby realizing the reciprocating motion of the vertical frame and further accelerating the removal of scraps from the cutting surface.

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1 - Figure 8As shown, a molding and cutting device for processing ultra-lightweight and high-strength mullite corundum lightweight bricks includes a concave operating frame 1, a square platform 2, and a top frame 3. The bottom of the platform 2 is movably connected to the center of the bottom inner wall of the operating frame 1 via a pivot. The top frame 3 is movably set on the top surface of the operating frame 1 and located above the platform 2. The front half of the top frame 3 is open, and the front and rear ends of the top frame 3 are provided with a sloping groove 301 on one side.

[0032] Furthermore, the inclined groove 301 is provided with a transverse groove 302 at both ends, and two sets of round shafts 78 are slidably connected inside the transverse groove 302 near the bottom. The top of the top frame 3 is fixedly installed with uprights 4 at the four corners, and the inner wall of the top of the operating frame 1 is fixedly installed with inserts 5 at the corresponding positions of the four sets of uprights 4. The four sets of uprights 4 are inserted into the corresponding inserts 5, and the section of the outer wall of the uprights 4 inside the inserts 5 is wound with spring coils 6. A positioning component 7 is provided on one side of the shelf 2.

[0033] The positioning component 7 includes a cylinder 71, which is located on the inner wall of the operating frame 1 away from the opening. A push rod 72 is provided at one end of the cylinder 71. A concave abutment frame 73 is fixedly installed at the end of the push rod 72 away from the cylinder 71. Abutment pieces 74 are movably connected to the front and rear inner walls of the concave abutment frame 73. The two sets of abutment pieces 74 are set with a beveled end near the opening of the concave abutment frame 73. Long rods 75 are fixedly installed at the ends of the two sets of abutment pieces 74 away from each other and on both sides. One end of the long rod 75 passes through and extends to the outside of the concave abutment frame 73. A spring coil 76 is provided between the abutment piece 74 and the inner wall of the concave abutment frame 73 on the outside of the long rod 75. A vertical plate 77 is fixedly installed on the top surface of the concave abutment frame 73 on one side of the front and rear frame. A round shaft 78 is fixedly installed at the top of the two sets of vertical plates 77 opposite to each other.

[0034] Place the entire brick blank at the center of the surface of the platform 2, and then start the cylinder 71. The cylinder 71 drives the concave abutment frame 73 to move using the push rod 72. The opening of the concave abutment frame 73 is aligned with the brick blank. As the concave abutment frame 73 continues to move, the beveled surfaces of the two sets of abutment plates 74 move toward the front and rear ends of the brick blank respectively. The two sets of abutment plates 74 are used to adaptively clamp and straighten the brick blank to reduce the brick blank from shifting during subsequent cutting. At the same time, it reduces the unevenness caused by the separation of several sets of blank strips during directional and fixed-distance cutting, which affects the effect of subsequent longitudinal cutting into blocks.

[0035] At the same time, the two sets of upright plates 77 move synchronously with the concave abutment frame 73, and the round shaft 78 first moves along the inside of the transverse groove 302, and then moves sequentially to the inside of the inclined groove 301. As a result, the top frame 3 is pulled down and sinks, and the four sets of upright rods 4 also move down along the inside of the insert 5, forcing the spring coil 6 to compress. As the top frame 3 sinks, the cutting parts inside it also get closer to the brick blank, which facilitates the directional cutting of the subsequent brick blank.

[0036] After the blank is horizontally cut into several strips by the cutting mechanism 8, the cylinder 71 drives the concave abutment frame 73 to move in the opposite direction, and the concave abutment frame 73 moves away from the strips. At the same time, the round shaft 78 slides from the inclined groove 301 to the bottom horizontal groove 302, and under the rebound force of the spring coil 6, it forces the top frame 3 to return to its original position. Thus, the top frame 3 also moves away from the strips. Then, the bottom pivot of the table 2 is rotated to ninety degrees to adjust the placement angle of the strips. The above clamping process is repeated to clamp and straighten the longitudinally placed strips so that the strips can be cut into blocks longitudinally.

[0037] Example 2: Please refer to Figure 4 As shown, movable grooves 303 are provided on the inner walls of the top frame 3 at the ends away from the opening. A sliding plate 304 is connected between the two sets of movable grooves 303. A cylinder 306 is provided between the sliding plate 304 and the inner wall of one side of the top frame 3 via a push rod 305. An L-shaped fixing frame 307, three-quarters of its own length, is provided on the side of the sliding plate 304 away from the cylinder 306. A sliding groove 308 is provided on the opposite sides of the sliding plate 304 and the L-shaped fixing frame 307. A cutting mechanism 8 is provided at the rear end between the two sets of sliding grooves 308.

[0038] A crossbar 309 is fixedly installed at the rear end of the inner wall of the top frame 3 near the opening, and a round shaft 310 is fixedly installed at one end of the bottom surface of the crossbar 309; when the top frame 3 sinks to the top of the billet, the cylinder 306 is started, and the push rod 305 drives the slide plate 304, the L-shaped fixing frame 307 and the cutting mechanism 8 to reciprocate, and the end of the slide plate 304 moves along the inside of the movable groove 303, and the cutting mechanism 8 cuts the billet at a fixed distance.

[0039] Please see Figure 4 - Figure 6 As shown, the cutting mechanism 8 includes a first horizontal frame 81 and a second horizontal frame 82. The first horizontal frame 81 and the second horizontal frame 82 are distributed front to back and slidably connected inside the first sliding groove 308. The first horizontal frame 81 and the second horizontal frame 82 are fixedly connected at both ends by connecting rods. A pusher 83 is fixedly installed at the tail end of the second horizontal frame 82 away from the first horizontal frame 81. Several sets of inclined grooves 84 are evenly arranged on the top surface of the pusher 83. A straight groove 85 is provided on the surface of the pusher 83 between the beginning and end of two adjacent sets of inclined grooves 84. A rectangular inner groove 86 is provided near one end of both the first horizontal frame 81 and the second horizontal frame 82.

[0040] A dual-axis motor 87 is provided near one end between the first horizontal frame 81 and the second horizontal frame 82. The front and rear bearings of the dual-axis motor 87 extend into the corresponding rectangular inner groove 86 and are respectively fixedly installed with a saw toothed disc 88 and a turntable 89. The bottom of the saw toothed disc 88 extends to the outside of the rectangular inner groove 86. Before the brick blank is cut, the first horizontal frame 81 is located at the top of the blank and the saw toothed disc 88 is located at the starting end of the side of the blank. Then, the second cylinder 306 is started, which drives the sliding plate 304, the first horizontal frame 81 and the second horizontal frame 82 to move to one side, and the saw toothed disc 88 moves in a straight line along the cutting point on the side of the blank.

[0041] At the same time, the dual-axis motor 87 is started, which drives the saw tooth disk 88 to rotate, so that the high-speed rotating blade can be used to cut the blank laterally. The saw tooth disk 88 moves to the other side of the blank, that is, the cylinder 2 306 drives the slide plate 304 to move back again, and the saw tooth disk 88 passes through the cutting line again to make additional cuts on the blank, so as to avoid some blanks still sticking together during the initial cutting. Thus, the saw tooth disk 88 slides back to its position with the horizontal frame 1 81 and is placed on the side of the blank.

[0042] As the cutting mechanism 8 gradually returns to its original position, the push bar 83 moves toward the crossbar 309, and the second round shaft 310 is inserted into the port of the second inclined groove 84. The second round shaft 310 and the second inclined groove 84 move relative to each other. The inner wall of the second round shaft 310 is resisted, which forces the first horizontal frame 81 and the second horizontal frame 82 to move. As a result, the sawtooth disk 88 moves sequentially and equidistantly to the next cutting point on the side of the blank until the second round shaft 310 moves to the outside of the second inclined groove 84. The above cutting operation is repeated. The push bar 83 moves in the opposite direction and away from the crossbar 309. At this time, the second round shaft 310 moves relative to the corresponding straight groove 85 until it is separated from the vertical groove 85.

[0043] This process is repeated, which facilitates the automatic fixed-distance displacement of the saw blade 89 to complete the transverse fixed-distance cutting of the blank. After the transverse switching is completed, the positioning mechanism 7 loses its grip on the blank strip and rotates the bottom pivot of the platform 2 to ninety degrees, forcing several groups of blank strips to also rotate ninety degrees. Then, the above cutting process is repeated to longitudinally cut the blank strips. This structure realizes the alternating transverse and longitudinal fixed-distance cutting of the blank, so as to simultaneously divide multiple groups of lightweight bricks, thereby improving the processing efficiency of lightweight bricks.

[0044] Example 3: Please refer to Figure 7 - Figure 8 As shown, a round block 810 is fixedly installed at one end of the center of the side of the turntable 89 away from the sawtooth disk 88. The round block 810 is slidably connected to a vertical frame 811. The upper and lower ends of the vertical frame 811 extend to the outside of the rectangular inner groove 86, and the bottom of the vertical frame 811 is set with a conical rough surface. A movable shaft 812 is fixedly installed at the center of the side of the vertical frame 811 away from the round block 810, and the movable shaft 812 is slidably connected to the inside of the groove 813 opened in the inner wall of the corresponding rectangular inner groove 86.

[0045] As the cutting mechanism 8 moves forward, the horizontal frame 81 and the toothed disc 88 move sequentially to the next cutting point of the brick blank, while the turntable 89 moves sequentially to the position where the blank has been cut. The vertical frame 811 is aligned with the side of the cutting line. As the cylinder 306 pulls the cutting mechanism 8 to move, the bottom tip of the vertical frame 811 is inserted into the cutting interval and uses its rough surface to rub and remove the protruding scraps on the cutting surface of the lightweight brick, keeping the cutting surface of the lightweight brick smooth. At the same time, the dual-axis motor 87 drives the toothed disc 88 to rotate while also making the turntable 89 rotate. The round block 810 slides up and down along the inside of the vertical frame 811 while rotating with the turntable 89, so as to force the vertical frame 811 to move back and forth, so as to further rub the cutting surface of the blank and improve the cutting effect of the lightweight brick.

[0046] In summary, when using this invention, the entire brick blank is first placed at the center of the surface of the platform 2, and then the cylinder 71 is activated. The push rod 72 drives the concave abutment frame 73 to move, and the opening of the concave abutment frame 73 is aligned with the brick blank. As the concave abutment frame 73 continues to move, the oblique surfaces of the two sets of abutment plates 74 move toward the front and rear ends of the brick blank, respectively. The two sets of abutment plates 74 are used to adaptively clamp and straighten the brick blank.

[0047] At the same time, the two sets of upright plates 77 move synchronously with the concave abutment frame 73, and the round shaft 78 first moves along the inside of the transverse groove 302, and then moves sequentially to the inside of the inclined groove 301. As a result, the top frame 3 is pulled down and sinks, and the four sets of upright rods 4 also move down along the inside of the insert 5. The spring coil 6 is compressed. As the top frame 3 sinks, the transverse frame 81 is located at the top of the billet, and the serrated disc 88 is located at the starting end of the side of the billet.

[0048] Next, cylinder 2 306 is started, which drives slide plate 304, cross frame 1 81 and cross frame 2 82 to move to one side, while saw tooth disk 88 moves in a straight line along the cutting point on the side of the billet. At the same time, dual-axis motor 87 is started, which drives saw tooth disk 88 to rotate. The high-speed rotating blades cut the billet laterally. Saw tooth disk 88 moves to the other side of the billet, and then cylinder 2 306 drives slide plate 304 back. Saw tooth disk 88 passes through the cutting line again to make additional cuts on the billet, so as to prevent some billets from sticking together during the initial cutting. Thus, saw tooth disk 88 slides back to its original position with cross frame 1 81 and is placed on the side of the billet.

[0049] As the cutting mechanism 8 gradually returns to its original position, the push bar 83 moves towards the crossbar 309, and the second round shaft 310 is inserted into the end of the second inclined groove 84. The second round shaft 310 and the second inclined groove 84 move relative to each other. The inner wall of the second round shaft 310 is pushed, which forces the first horizontal frame 81 and the second horizontal frame 82 to move. As a result, the saw tooth disk 88 moves sequentially to the next cutting point on the side of the blank. The above operation is repeated, and so on, to complete the transverse fixed-distance division of the blank.

[0050] Finally, rotate the bottom pivot of the platform 2 to ninety degrees, forcing the several groups of blank strips that have been horizontally cut on the top surface of the platform 2 to also rotate ninety degrees. Then repeat the above cutting process and cut the blank strips vertically so as to divide multiple groups of lightweight bricks at the same time.
