Description

Technical Field

[0001] The invention relates to the field of extrusion molding, and in particular to an automatic cutting and extrusion molding device for ceramic brick electric kiln blanks. Background Art

[0002] The traditional flat plate extrusion forming method of ceramic tiles is: first filter the 38% water slurry into 18-20% mud, use a vacuum mud machine to vacuum mud, then age for 24 hours, add the extruder to extrude a flat plate of a certain width and thickness, and then use a roller to mold the required concave and convex patterns on the surface of the flat plate. Cut it into the required size and put it into the drying kiln for drying.

[0003] In the traditional flat plate extrusion of ceramic tiles, the width-to-thickness ratio cannot be too large due to the differences in extrusion pressure and material uniformity in the width and thickness directions when the clay material is pushed forward for extrusion. The current width-to-thickness ratio of extrusion molding does not exceed 40, which means that the width of the extruded plate is 800mm and the thickness is not less than 20mm. The ceramic tiles on the market are usually 10mm thick and 300-1200mm wide, and the specifications are getting larger and larger. Due to the problems of internal uniformity and extrusion stress, the traditional extrusion molding uses a round roller to increase the width after the plate material is extruded. It can meet the requirements of ceramic tiles with specifications less than 600*600mm, while the common large-sized ceramic tiles on the market, such as 800*800mm, 1200*2400, etc., still have the problem of uneven shrinkage and deformation in various parts. Summary of the invention

[0004] In order to overcome the problems that the width-to-thickness ratio of the clay blank cannot be too large during the extrusion of traditional ceramic tile flat plates, large-sized ceramic tile blanks have the problem of uneven shrinkage and deformation in various parts, and the position of the clay blank needs to be manually adjusted multiple times during the rolling process so that the clay blank can be aligned with the rolling roller.

When the circular mud blanks are separated, under the buffering effect of the arc-shaped baffle, the circular mud blanks can be prevented from falling too quickly due to gravity in the latter half of the circle, causing microcrack damage, thereby improving the quality of the circular mud blanks after separation, thereby improving the precision and quality of the ceramic tiles after forming.

[0016] 2. Due to the size difference between the inner and outer surfaces of the circular mud blank, radial extension is carried out on the basis of the circle.

[0017] 3. The connecting frame drives the pressing plate to move, and the reset spring is compressed accordingly. After the pressing plate moves, it presses the circular ring clay blank being cut, thereby preventing the circular ring clay blank from loosening during the cutting process, thereby improving the flatness of the circular ring clay blank during cutting, and further improving the quality of the circular ring clay blank, thereby further improving the accuracy and quality of the ceramic after forming.

[0018] 4. The gears continuously rotate forward and reverse, driving the two driven racks to move back and forth continuously. The two driven racks drive the two correction plates to move continuously toward or away from each other. The two correction plates can perform centering correction on the unfolded circular mud blank, so that the unfolded circular mud blank can be more accurately aligned with the three calendering rollers, trimming rollers and embossing rollers, thereby improving the quality of the unfolded circular mud blank after rolling, thereby further improving the precision and quality of the ceramic tile after forming.

The electric ring slider 92 will slide along the annular guide rail 91. A hydraulic rod 93 is fixedly installed on the electric ring slider 92, and a ring cutting knife 94 is installed on the telescopic rod of the hydraulic rod 93.

[0041] The cutting mechanism includes a transverse guide rail 101, an electric transverse slider 102 and a cutting knife 103.

[0042] The calendering mechanism includes a base frame 111, an electric conveying roller 112, a conveying belt 113, a side frame 114, a support plate 115, a calendering roller 116, a trimming roller 117 and an embossing roller 118. The base frame 111 is installed on the base plate 1, two electric conveying rollers 112 are rotatably arranged on the base frame 111, a conveying belt 113 is wound between the two electric conveying rollers 112, two side frames 114 are installed on the base frame 111, and a support plate 115 is installed between the middle parts of the two side frames 114. Plate 115, the support plate 115 is located inside the conveyor belt 113, the support plate 115 is fitted with the inner top of the conveyor belt 113, and three calendering rollers 116 for rolling the circular mud blanks, a trimming roller 117 for trimming the circular mud blanks, and an embossing roller 118 for embossing the circular mud blanks are rotatably installed in sequence between the upper parts of the two side frames 114 in the direction away from the circular mud blank extruder 7, and the electric push rod, the electric roller body, the electric ring slider and the electric cross slider are all powered by the electric slip ring.

[0043] The curvature of the rolled surfaces of the three rolling rollers 116 from the middle to the two ends is a gradual arc shape, and the spacing between the three rolling rollers 116 and the supporting surface on the conveyor belt 113 towards the trimming roller 117 is from large to small. The minimum spacing between the rolling roller 116 and the supporting surface on the conveyor belt 113 is equal to the required brick thickness, the embossing surface on the trimming roller 117 is straight, and the embossing roller 118 is provided with a concave and convex texture.

[0044] The operator first delivers an appropriate amount of mud material into the circular mud blank extruder 7 through the hollow feeding pipe 3, and then controls the telescopic rods of the two electric push rods 82 near the inspection door 21 to shorten, and the telescopic rods of the two electric push rods 82 drive one of the sliding frames 81, the electric roller body 83, the support roller 84 and the arc baffle 85 to move toward the direction close to the circular mud blank extruder 7. After the electric roller body 83 and the support roller 84 are aligned with the circular mud blank extruder 7, the telescopic rods of the two electric push rods 82 stop shortening, and the circular mud blank extruder 7 extrude the circular mud blank onto the electric roller body 83 and the support roller 84. After the circular mud blank is squeezed to the required length, the operator controls the telescopic rod of the hydraulic rod 93 to extend to drive the ring cutter 94 to move and insert the circular mud blank. Then the operator controls the electric ring slider 92 to move 360 ​​degrees along the annular guide rail 91 and then stop, the electric ring slider 92 drives the ring cutter 94 to cut the circular mud blank, and then the operator controls the telescopic rod of the hydraulic rod 93 to shorten and drive the ring cutter 94 to move and reset; then the operator controls the telescopic rods of the two electric push rods 82 near the inspection door 21 to extend, and the telescopic rods of the two electric push rods 82 drive one of the sliding frames 81, the electric roller body 83, the support roller 84, the arc baffle 85 and the cut circular mud blank to move away from the circular mud blank extruder 7, and after the sliding frame 81, the electric roller body 83, the support roller 84 and the arc baffle 85 move and reset, the telescopic rods of the two electric push rods 82 stop extending;Then the operator starts the output shaft of the servo motor 5 and rotates it 90 degrees and then stops. The output shaft of the servo motor 5 drives the cross guide frame 4 to rotate 90 degrees and then stop through the transmission assembly 6. The cross guide frame 4 drives four sliding frames 81, eight electric push rods 82, four electric roller bodies 83, a number of support rollers 84 and four arc baffles 85 to rotate 90 degrees and then stop. One of the sliding frames 81, the electric roller bodies 83, the support rollers 84, the arc baffles 85 and the cut circular mud blanks move to the top of the conveyor belt 113, and the other sliding frame 81, the electric roller body 83, the support rollers 84 and the arc baffles 85 move to the circular mud blank extruder 7 to support the extruded circular mud blank again. This is repeated, so that the four sliding frames 81, the electric roller bodies 83, the support rollers 84 and the arc baffles 85 can be moved to the circular mud blank extruder 7 to support the extruded circular mud blank again. The frame 81, four electric roller bodies 83, four supporting rollers 84 and four arc-shaped baffles 85 work alternately in turn. After the cut circular mud blank moves to the top of the conveyor belt 113, the operator starts the electric horizontal slide block 102 to move back and forth along the horizontal guide rail 101 and then stops. The electric horizontal slide block 102 drives the cutting knife 103 to cut the circular mud blank, and then controls the electric roller body 83 and several supporting rollers 84 to rotate 360 ​​degrees and then stop. The cut circular mud blank is separated from the electric roller body 83 and several supporting rollers 84 radially from the bottom, and the circular mud blank is extruded through the circular mud blank extruder 7. The uniformity of each part of the circular mud blank is significantly improved compared with the flat plate, which can meet the requirements of uniform density of each part of large-sized flat bricks, avoiding the occurrence of sintering. Uncontrollable deformation occurs. When the circular mud blank is separated, the buffering effect of the arc baffle 85 can prevent the circular mud blank from falling too quickly due to gravity when it is in the latter half of the circle, causing microcrack damage, thereby improving the quality of the circular mud blank after separation, thereby improving the accuracy and quality of the ceramic tile after molding; at the same time, the operator starts the rotation of the two electric conveying rollers 112, and the two electric conveying rollers 112 drive the conveyor belt 113 to move. The speed of the electric roller body 83 and the supporting roller 84 for separating the circular mud blank is adjusted by the rotation speed of the electric roller body 83, and matches the moving speed of the conveyor belt 113. After the cut circular mud blank is unfolded on the conveyor belt 113, it passes through three calendering rollers 116, trimming rollers 117 and embossing rollers 118 in sequence. The curvature of the calendering surface of the calendering roller 116 from the middle to the two ends is in a gradually changing arc shape. The spacing between the three calendering rollers 116 and the supporting surface on the bottom conveyor belt 113 is from large to small. When the unfolded circular mud blank is calendered, the thickness of the unfolded circular mud blank is gradually thinned and the width is widened, and the mud material is gradually formed to the required size. Under the action of the support plate 115, the contact surface of the conveyor belt 113 with the three calendering rollers 116, the trimming roller 117 and the embossing roller 118 will not be deformed. After the rolled circular mud blank passes through the trimming roller 117, the overall thickness becomes uniform. When the circular mud blank trimmed to the required thickness passes through the embossing roller 118, the embossing roller 118 embosses the circular mud blank with the required concave and convex patterns, and then cuts it into the required size before entering the next process.Since there is a size difference between the inner and outer surfaces of the circular mud blank, it is radially extended on the basis of the circle, and the three calendering rollers 116 are radially calendered from the circumference. During the calendering, the inner surface is further squeezed and extended to make up for the size difference generated when the inner and outer surfaces of the circular ring are expanded, and the quality of the circular mud blank is further improved, thereby further improving the accuracy and quality of the ceramic tile after forming. When the device needs to be repaired, the operator can open the two inspection doors 21 to repair the device. ;

[0045] Embodiment 2: Based on embodiment 1, Figure 8-Figure 12 As shown, it also includes a pressing mechanism, which is arranged on the arc baffle 85 and the cutting mechanism. The pressing mechanism is used to press the cut circular mud blank. The pressing mechanism includes a pressing plate 121, a connecting frame 122, a return spring 123 and a roller 124. A pressing plate 121 for pressing the circular mud blank is slidably provided on each arc baffle 85. The pressing plate 121 passes through the arc baffle 85. A connecting frame 122 is installed on the pressing plate 121. Both sides of the connecting frame 122 are set as inclined surfaces. A plurality of return springs 123 are connected between the connecting frame 122 and the arc baffle 85. A roller 124 is provided on the electric cross slide 102, and the roller 124 contacts one of the inclined surfaces on the connecting frame 122.

[0046] When the electric horizontal slider 102 moves back and forth, it drives the roller 124 to move back and forth. After the roller 124 contacts the inclined surface on the connecting frame 122, the connecting frame 122 will move in the direction close to the arc baffle 85, and the connecting frame 122 drives the pressing plate 121 to move, and the reset spring 123 is compressed accordingly. After the pressing plate 121 moves, it presses the circular ring clay blank being cut, thereby preventing the circular ring clay blank from loosening during the cutting process, thereby improving the flatness of the circular ring clay blank during cutting, and further improving the quality of the circular ring clay blank, thereby further improving the accuracy and quality of the ceramic after forming. After the electric horizontal slider 102 drives the roller 124 to reset, the roller 124 contacts one of the inclined surfaces on the connecting frame 122 again, and under the action of the reset spring 123, the connecting frame 122 drives the pressing plate 121 to move and reset, and the pressing plate 121 no longer presses the cut circular ring clay blank.

[0047] Embodiment 3: Based on embodiment 2, Figure 14-16As shown, it also includes a correction mechanism, which is arranged on the calendering mechanism. The correction mechanism is used to correct the mud blanks that have been cut and dropped on the conveyor belt 113. The correction mechanism includes a corrugated groove circular plate 131, a driving frame 132, a driving rack 133, a gear 134, a driven rack 135 and a correction plate 136. A corrugated groove circular plate 131 is installed on both sides of one of the electric conveying rollers 112. A corrugated groove is opened on the side away from each other of the two corrugated groove circular plates 131. A driving frame 132 is slidably provided at the bottom of the support plate 115. Two protrusions are provided on one side of the driving frame 132. The driving frame 132 is provided with two protrusions. The two protrusions on the frame 132 are respectively located in the corrugated grooves opened on the two corrugated groove circular plates 131. A driving rack 133 is installed on the other side of the driving frame 132. A gear 134 is rotatably provided at the bottom of the support plate 115. The driving rack 133 is engaged with the gear 134. Two driven racks 135 are slidably provided at the bottom of the support plate 115. The two driven racks 135 are respectively located on both sides of the gear 134. The two driven racks 135 are engaged with the gear 134. A correction plate 136 for correcting the circular mud blank is installed on the side of the two driven racks 135 away from each other.

[0048] The two correction plates 136 are both located above the conveyor belt 113 , and one side of the two correction plates 136 close to the corrugated groove circular plate 131 is configured as an arc surface.

[0049] Since the sides of the two correction plates 136 close to the corrugated groove circular plate 131 are both set as cambered surfaces, the unfolded circular mud blank can more conveniently enter between the two correction plates 136 when moving on the conveyor belt 113. When one of the electric conveying rollers 112 rotates, it drives the two corrugated groove circular plates 131 to rotate. Under the action of the two corrugated grooves on the two corrugated groove circular plates 131, the driving frame 132 and the driving rack 133 will continuously reciprocate, and the driving rack 133 drives the gear 134 to continuously rotate forward and reverse. The gear 134 continuously rotates forward and reverse. The rotation drives the two driven racks 135 to move back and forth continuously, and the two driven racks 135 drive the two correction plates 136 to move continuously toward or away from each other.
