Description

Technical Field

[0001] This invention belongs to the field of ceramic processing technology, and more specifically, it is a method for rolling ceramic gel material. Background Technology

[0002] Ceramics are crafted from aluminosilicate minerals or certain oxides as the main raw materials, and are produced according to human intentions through specific physical and chemical processes at high temperatures and in a certain atmosphere. They are crafted into a certain type of rock, and the surface may be glazed or unglazed. Some porcelains also have different degrees of translucency. The whole body is composed of one or more crystals or amorphous cements and microstructures such as pores or clinker inclusions.

[0003] Patent document CN109514699A discloses a method for rolling and forming ceramic blanks. During rolling and forming, the rolling head rotates in the opposite direction to the mold, causing the upper and lower sides of the ceramic blank to be pressed against the rolling head and the inner wall of the mold, respectively. A scraper is positioned at a fixed point and moves to the upper edge of the mold without contacting the rolling head. An air jet device is installed, with its nozzle pointing towards the upper edge of the mold without contacting the rolling head. The air jet nozzle and the scraper fixed point are located on the upper sides of the pressing area. This method is applicable to the forming and processing of various shapes of bowls and plates. During the rolling and forming process, it can control the flatness of the upper edge of the bowl and plate blank and automatically collect excess ceramic scrap, preventing it from accidentally falling into the bowl or plate blank.

[0004] The above-mentioned process has certain shortcomings when performing ceramic gel roll forming. Roll forming is mainly suitable for forming bowls and plates. However, bowls and plates of different sizes have different rim sizes. During the roll forming process, the rims need to be cut. The above method cannot be adjusted according to the size of the rim, reducing the flexibility of the rim trimming operation. Secondly, during the roll forming process, the dried blanks need to be trimmed. However, the traditional method cannot trim multiple blanks at the same time, resulting in low efficiency and errors that are prone to occur during trimming, causing the shapes of multiple blanks to be different, reducing the trimming accuracy. Furthermore, the traditional method generates a lot of dust during trimming. The open operation results in a high dust content in the working environment, which poses a certain health hazard to users. Summary of the Invention

[0005] The purpose of this invention is to provide a method for rolling ceramic gel materials, which can solve the existing problems.

[0006] The problem solved by this invention is:

[0007] 1. Roll forming process is mainly applicable to the forming and processing of bowls and plates. However, bowls and plates of different sizes have different mouth sizes. During the roll forming operation, the mouth needs to be rolled and cut. The above method cannot be adjusted according to the size of the bowl and plate mouth, which reduces the flexibility of the mouth trimming operation.

[0008] 2. Secondly, during the roll forming process, the dried blanks need to be trimmed. However, the traditional method cannot trim multiple blanks at the same time, which is inefficient. Furthermore, errors are prone to occur during the trimming process, resulting in different shapes among the multiple blanks and reducing the trimming accuracy.

[0009] 3. Secondly, traditional methods generate a lot of dust during the trimming process. The open-air operation results in a high dust content in the working environment, which poses a certain threat to the health of users.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A method for rolling ceramic gel material includes the following steps:

[0012] Step 1: Place the ceramic gel material into a fully automatic clay extruder and use the fully automatic clay extruder to mix and extrude the ceramic gel material. Then, according to the ceramic processing requirements, cut the extruded ceramic gel material into blocks of the same size.

[0013] Step 2: Install the upper and lower molds of the steel mold onto the rotating platen and rotating base of the automatic rolling machine. First, place the slit ceramic gel material into the lower mold, cover the upper mold on top of the lower mold, and then use the rotation of the upper and lower molds to roll and shape the ceramic gel material. At the same time, use the edge trimming knife to cut off the scraps of the ceramic gel material to make a blank. Let the blank dry naturally to remove its excess moisture.

[0014] Step 3: Place the two sets of dried billets on the rotating chucks on both sides of the trimming machine, and then place the sample piece for comparison on the rotating chuck in the middle. Drive the three sets of rotating chucks to rotate through the motor and chain, so that the positioning rod of the trimmed piece moves along the surface of the sample piece. During the rotation of the billet, the cutting bar moves synchronously, completing the synchronous trimming operation of the two sets of billets.

[0015] Step 4: Place the trimmed blank in the kiln and fire it to evaporate and remove the colloid in the ceramic gel material, thus completing the bisque firing and colloid removal process of the blank.

[0016] Step 5: Apply glaze to the surface of the fired blank, and then place the glazed blank back into the kiln for firing to allow the glaze on the surface of the blank to solidify, thus completing the glaze firing process.

[0017] As a further technical solution of the present invention, when the automatic rolling press is in use, the user starts the hydraulic rod, which in turn drives the rotating disk downward by using the lifting rod and rotating base, thereby covering the rotating disk on top of the rotating base, so that the upper and lower molds of the steel film are pressed together, and the ceramic gel material is pressed into shape.

[0018] As a further technical solution of the present invention, when the automatic rolling machine is in use, the first motor drives the rotating disk to rotate, and the second motor drives the rotating base to rotate, so that the upper and lower molds of the steel film rotate, causing the cutting head of the trimming knife holder to contact the opening of the blank and rotate to remove the excess ceramic gel material at the opening.

[0019] As a further technical solution of the present invention, when the trimming knife holder is in use, the position of the knife head is adjusted laterally by means of the horizontal tie rod, and the position of the knife head is adjusted up and down by means of the lifting tie rod, so that the adjusted knife head is close to the opening of the blank.

[0020] As a further technical solution of the present invention, when the trimming knife holder is used, the baffle on the knife head allows the ceramic gel material after being rotated and cut to fall into the feed hopper, and then be discharged into the collection box for collection.

[0021] As a further technical solution of the present invention, when the blank is used, the lifting rod is pulled up by the lifting rod, so that the lifting rod drives the cutting rod and the positioning rod to move synchronously. When the positioning rod moves along the surface of the sample, the fixing frame and the limiting rod are used to drive the two sets of cutting rods to move in the same position, and the blank surface is trimmed through the ends of the two sets of cutting rods.

[0022] As a further technical solution of the present invention, when the blank is used, the tension spring and the limiting rod are used to push the fixing frame to move horizontally, so that the positioning rod on the fixing frame is in close contact with the surface of the sample part, and the positioning rod and the tool bar move synchronously, so that the tool bar is in close contact with the surface of the blank.

[0023] As a further technical solution of the present invention, when the trimming machine is in use, the lifting top rod and the limiting sliding buckle drive the lifting baffle to move upward, and then rotate the side rotating cover plate so that the side rotating cover plate covers the upper part of the lifting baffle, thereby sealing and isolating it during the trimming operation.

[0024] As a further technical solution of the present invention, the automatic rolling press includes a fixed base, a rotating disk, and a rotating base. The rotating base is movably installed at the upper middle part of the fixed base, and the rotating disk is movably installed at the upper part of the rotating base. The rotating disk is driven by a first motor, and the rotating base is driven by a second motor. A rotating rod is installed at the lower middle part of the rotating base. A lifting rod for adjusting the position of the rotating disk is provided at the upper end of the fixed base. One end of the lifting rod is movably connected to the fixed base through the rotating base. A trimming knife holder is installed on one side of the lifting rod. The trimming knife holder includes a lifting rod and a transverse rod. The lifting rod is movably installed at one end of the transverse rod. Both the lifting rod and the transverse rod are locked and fixed by bolts.

[0025] A cutter head is movably mounted on the lower end of the lifting rod, and a baffle is mounted on the tail of the cutter head. The fixed base has an internal fixed base for use with the trimming cutter holder. A weighing base is located at the bottom of the fixed base, and a feeding hopper is located at the upper end of the fixed base. The trimming machine includes a fixed base and a trimming component. The trimming component is movably mounted on the upper part of the fixed base. A lifting baffle is movably mounted on the outer side surface of the fixed base. Three sets of rotating brackets are movably mounted on the upper outer surface of the fixed base. The three sets of rotating brackets are synchronously driven by a motor, gears, and a chain. The trimming component includes a moving frame and a fixed frame. The movable frame is movably installed on one side of the fixed frame. The two ends of the movable frame and the fixed frame are movably connected by a limiting rod. A tension spring is sleeved on the outer surface of the limiting rod. Two tool bars and a positioning rod are fixedly installed on the outer surface of one side of the fixed frame. One end of the positioning rod is provided with a roller. One end of the tool bar has a beveled structure. A lifting rod is provided in the middle of the upper end of the movable frame. The fixed base and the lifting cover are movably connected by a lifting top rod. A side rotating cover plate is movably installed on one side of the lifting cover. The fixed base and the lifting cover are slidably connected by a limiting sliding buckle. The upper end of the fixed base is provided with a fixed side plate for use with the blank.

[0026] The beneficial effects of this invention are:

[0027] 1. In the roll forming method for ceramic gel material, the edge trimming blade holder can be used for bowl and plate blanks of different diameters. During edge trimming, the blade can be adjusted according to the diameter, ensuring the blade head is flush with the end of the blank, thus expanding its applicability. During operation, the user activates the hydraulic rod, which, in conjunction with the lifting rod and rotating base, moves the rotating disk downwards, placing it over the rotating base. This causes the upper and lower molds of the steel die to press together, forming the ceramic gel material. This method is primarily used for pressing bowl and plate ceramic products. The user operates via the first motor... The rotating disk is driven to rotate, and then the rotating base is driven to rotate via the second motor, causing the upper and lower molds of the steel mold to rotate. This causes the cutting head of the trimming knife holder to contact the opening of the blank, cutting off the excess ceramic gel material at the opening. When adjusting the trimming knife holder, the position of the cutting head is adjusted laterally by the horizontal tie rod and vertically by the lifting tie rod, so that the adjusted cutting head is close to the opening of the blank. The horizontal tie rod and the lifting tie rod are then locked and fixed by the bolt. Finally, the baffle on the cutting head causes the ceramic gel material that has been cut off to fall into the feeding hopper, and then into the receiving box for collection, completing the automatic material collection operation.

[0028] 2. In the roll forming process of ceramic gel material, by setting up a trimming component, multiple blanks can be trimmed simultaneously and precisely, improving trimming efficiency and accuracy while reducing errors between multiple blanks. During operation, a sample for comparison is first placed on a central rotating chuck. The blank is trimmed based on the sample's shape. A motor and chain drive three sets of rotating chucks to rotate, causing the blanks and sample mounted on the three sets to rotate synchronously. A tension spring and a limiting rod push the fixing frame to translate, ensuring the positioning rod on the fixing frame is in close contact with the sample surface, and simultaneously ensuring the cutter bar is in close contact with the sample surface. The tool holder and positioning rod are set to move synchronously, ensuring the tool holder is in close contact with the blank surface. A lifting rod is then used to pull the lifting rod upwards, causing the tool holder and positioning rod to move upwards synchronously, so that the positioning rod moves against the sample surface. Simultaneously, the tool holder moves to the same position. A fixed frame, in conjunction with a limiting rod, moves both sets of tool holders in the same position. The ends of the two sets of tool holders trim the blank surface, causing the positioning rod of the trimmed blank to move along the sample surface. During the blank's rotation, the tool holder moves synchronously, completing the synchronous trimming operation for both sets of blanks. Using the sample as a reference, the synchronous movement of the tool holder and positioning rod allows for precise replication of the sample, simultaneously completing the trimming operation for both sets of blanks.

[0029] 3. When performing the roll forming operation of ceramic gel material using this roll forming method, by setting up a lifting baffle, the user can drive the lifting baffle to move upward by using the lifting top rod in conjunction with the limiting sliding buckle during the blank trimming operation. This allows the lifting baffle to block the side of the three sets of rotating brackets. Then, the side rotating cover plate is rotated so that it covers the upper part of the lifting baffle. During the blank trimming operation, this seals and isolates the material, preventing the blank dust from scattering. Attached Figure Description

[0039] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0040] like Figure 1-7As shown, a method for rolling ceramic gel material includes the following steps:

[0041] Step 1: Place the ceramic gel material into a fully automatic clay extruder and use the fully automatic clay extruder to mix and extrude the ceramic gel material. Then, according to the ceramic processing requirements, cut the extruded ceramic gel material into blocks of the same size. The ceramic gel material is composed of potassium feldspar, sodium feldspar, quartz, aluminum powder, DMAA gel and MBAA gel.

[0042] Step 2: Install the upper and lower molds of the steel mold onto the rotating platen 8 and rotating base 9 of the automatic rolling machine, respectively. First, place the slit ceramic gel material into the lower mold, cover the upper mold on top of the lower mold, and then use the rotation of the upper and lower molds to make the ceramic gel material complete the rolling and shaping operation on the upper and lower molds. At the same time, the edge trimming knife holder 4 trims off the scraps of the ceramic gel material to make a blank. Let the blank dry naturally to remove its excess moisture.

[0043] Step 3: Place the two sets of dried billets on the rotating chucks 20 on both sides of the trimming machine, and then place the sample piece for comparison on the rotating chuck 20 in the middle. The motor and chain drive the three sets of rotating chucks 20 to rotate, so that the positioning rod 28 of the trimming piece 21 moves along the surface of the sample piece. During the rotation of the billet, the cutter bar 23 moves synchronously, completing the synchronous trimming operation of the two sets of billets.

[0044] Step 4: Place the trimmed blank in the kiln and fire it to evaporate and remove the colloid in the ceramic gel material, thus completing the bisque firing and colloid removal process of the blank.

[0045] Step 5: Apply glaze to the surface of the fired blank, and then place the glazed blank back into the kiln for firing. This allows the glaze on the surface of the blank to solidify, completing the glaze firing process.

[0046] When using the automatic rolling press, the user activates the hydraulic rod 16, which, in conjunction with the lifting rod 5 and the rotating base 6, moves the rotating disk 8 downward, thereby covering the rotating base 9 with the rotating disk 8, so that the upper and lower molds of the steel film are pressed together, and the ceramic gel material is pressed into shape.

[0047] When the automatic rolling machine is in use, the first motor 7 drives the rotating disk 8 to rotate, and the second motor 10 drives the rotating base 9 to rotate, so that the upper and lower molds of the steel mold rotate, causing the cutter head 11 of the trimming knife holder 4 to contact the opening of the blank and rotate to remove the excess ceramic gel material at the opening.

[0048] When in use, the position of the cutting head 11 is adjusted laterally by the horizontal tie rod 14 and vertically by the lifting tie rod 13, so that the adjusted cutting head 11 is close to the opening of the blank.

[0049] When the trimming knife holder 4 is in use, the baffle 12 on the knife head 11 allows the ceramic gel material after being rotated and cut to fall into the feed hopper 17, and then be discharged into the collection box 2 for collection.

[0050] When the blank 21 is in use, the lifting rod 22 pulls the moving frame 29 upward, so that the lifting rod 22 drives the cutter bar 23 and the positioning rod 28 to move synchronously. When the positioning rod 28 moves along the surface of the sample part, the fixing frame 30, together with the limiting rod 26, drives the two sets of cutter bars 23 to move in the same position, and the blank surface is trimmed through the ends of the two sets of cutter bars 23.

[0051] When the blank 21 is used, the tension spring 27 and the limiting rod 26 are used to push the fixing frame 30 to move horizontally, so that the positioning rod 28 on the fixing frame 30 is in close contact with the surface of the sample part. The positioning rod 28 and the tool bar 23 move synchronously, so that the tool bar 23 is in close contact with the surface of the blank.

[0052] When the trimming machine is in use, the lifting top rod 32, in conjunction with the limiting sliding buckle 31, drives the lifting baffle 25 to move upward, and then rotates the side rotating cover plate 19 so that the side rotating cover plate 19 covers the upper part of the lifting baffle 25, thus sealing and isolating it during the trimming operation.

[0053] The automatic rolling press includes a fixed base 3, a rotating disk 8, and a rotating base 9. The rotating base 9 is movably installed in the middle of the upper end of the fixed base 3. The rotating disk 8 is movably installed in the upper part of the rotating base 9. The rotating disk 8 is driven by a first motor 7, and the rotating base 9 is driven by a second motor 10. A rotating rod 1 is installed in the middle of the lower end of the rotating base 9. A lifting rod 5 for adjusting the position of the rotating disk 8 is provided at the upper end of the fixed base 3. One end of the lifting rod 5 is movably connected to the fixed base 3 through the rotating base 6. A trimming knife holder 4 is installed on one side of the lifting rod 5.

[0054] The trimming knife holder 4 includes a lifting rod 13 and a transverse rod 14. The lifting rod 13 is movably installed at one end of the transverse rod 14. Both the lifting rod 13 and the transverse rod 14 are locked and fixed by bolts. A cutter head 11 is movably installed at the lower end of the lifting rod 13. A baffle 12 is installed at the tail of the cutter head 11. A weighing base 15 is provided at the bottom of the fixed base 3. A feed hopper 17 is provided at the upper end of the fixed base 3.

[0055] The trimming machine includes a fixed base 18 and a trimming component 21. The trimming component 21 is movably installed on the upper part of the fixed base 18. A lifting baffle 25 is movably installed on the outer side surface of the fixed base 18. Three sets of rotating brackets 20 are movably installed on the upper outer surface of the fixed base 18. The three sets of rotating brackets 20 are synchronously driven by a motor in conjunction with gears and chains.

[0056] The blanking piece 21 includes a movable frame 29 and a fixed frame 30. The movable frame 29 is movably installed on one side of the fixed frame 30. The two ends of the movable frame 29 and the fixed frame 30 are movably connected by a limiting rod 26. A tension spring 27 is sleeved on the outer surface of the limiting rod 26. Two cutting rods 23 and a positioning rod 28 are fixedly installed on the outer surface of one side of the fixed frame 30. One end of the positioning rod 28 is provided with a roller. One end of the cutting rod 23 has a bevel structure. A lifting rod 22 is provided in the middle of the upper end of the movable frame 29. The fixed base 18 and the lifting baffle 25 are movably connected by a lifting top rod 32. A side rotating cover plate 19 is movably installed on one side of the lifting baffle 25. The fixed base 18 and the lifting baffle 25 are slidably connected by a limiting sliding buckle 31. The upper end of the fixed base 18 is provided with a fixed side plate 24 for use with the blanking piece 21.

[0057] In this roll forming method for ceramic gel material roll forming, the edge trimming knife holder 4 is designed to accommodate bowl and plate blanks of different diameters. During edge trimming, the knife can be adjusted according to the diameter, ensuring the trimmer head 11 of the edge trimming knife holder 4 is flush with the end of the blank, thus expanding its applicability. During operation, the user activates the hydraulic rod 16, which, in conjunction with the lifting rod 5 and the rotating base 6, moves the rotating disk 8 downwards, placing it over the rotating base 9. This causes the upper and lower molds of the steel film to press together, forming the ceramic gel material. This method is primarily used for pressing bowl and plate ceramic products. The user also uses the first motor 7 to rotate the rotating disk 8. The second motor 10 drives the rotating base 9 to rotate, causing the upper and lower molds of the steel film to rotate, thereby making the cutter head 11 of the trimming knife holder 4 contact the opening of the blank and rotate to cut off the excess ceramic gel material at the opening. When the trimming knife holder 4 is adjusted, the position of the cutter head 11 is adjusted laterally by the horizontal tie rod 14 and the position of the cutter head 11 is adjusted up and down by the lifting tie rod 13, so that the adjusted cutter head 11 is close to the opening of the blank. The horizontal tie rod 14 and the lifting tie rod 13 are locked and fixed by the bolt body. Finally, the baffle 12 on the cutter head 11 allows the rotated ceramic gel material to fall into the feed hopper 17 and be discharged into the collection box 2 for collection, completing the automatic collection operation of the edge material.

[0058] In the roll forming method for ceramic gel material, by setting up a trimming part 21, multiple blanks can be precisely trimmed simultaneously during the trimming operation, improving trimming efficiency and accuracy, and reducing errors between multiple blanks. During operation, the sample for comparison is first placed on the central rotating bracket 20. The blank is trimmed by referring to the shape of the sample. A motor and chain drive the three sets of rotating brackets 20 to rotate, causing the blanks and sample mounted on the three sets of rotating brackets 20 to rotate synchronously. A tension spring 27, in conjunction with a limiting rod 26, pushes the fixing frame 30 to translate, so that the positioning rod 28 on the fixing frame 30 is in close contact with the sample surface, and simultaneously, the cutter bar 23 is in close contact with the sample surface. The setting of the fixing frame 30 ensures that the cutter bar 23 and the positioning rod... 28 moves synchronously, positioning rod 28 and cutter bar 23 move synchronously, so that cutter bar 23 is close to the surface of the blank. Then, lifting rod 22 is used to pull lifting rod 22 upward, so that lifting rod 22 drives cutter bar 23 and positioning rod 28 to move synchronously upward, so that positioning rod 28 moves along the surface of the sample part, and at the same time, cutter bar 23 moves to the same position. Fixing frame 30 and limiting rod 26 drive the two sets of cutter bars 23 to move in the same position. The ends of the two sets of cutter bars 23 trim the surface of the blank, so that positioning rod 28 of the trimmed blank 21 moves along the surface of the sample part. During the rotation of the blank, the cutter bar 23 moves synchronously, completing the synchronous trimming operation of the two sets of blanks. Using the sample part as a reference, the synchronous movement of cutter bar 23 and positioning rod 28 can accurately replicate the sample part and complete the trimming operation of the two sets of blanks at the same time.

[0059] When performing the roll forming operation of ceramic gel material using this roll forming method, by setting up a lifting baffle 25, the user can drive the lifting baffle 25 upward by using the lifting top rod 32 in conjunction with the limiting sliding buckle 31 during the blank trimming operation, so that the lifting baffle 25 blocks the side of the three sets of rotating brackets 20, and then rotate the side rotating cover plate 19 so that the side rotating cover plate 19 covers the upper part of the lifting baffle 25, thus sealing and isolating it during the blank trimming operation to prevent the blank dust from scattering.

[0060] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
