TECHNICAL FIELD

[0001] The application relates to the field of ceramic forming, in particular to a bacteriostatic and easy-to-clean ceramic preparation equipment and process. BACKGROUND

[0002] The bacteriostatic and easy-to-clean ceramic is a kind of ceramic material with special functions, which is endowed with the characteristics of bacteriostasis and easy cleaning by introducing specific chemical composition or structure on the ceramic surface. The ceramic rolling forming machine is a commonly used equipment in ceramic forming, which uses the rolling and pressing force to extend and press the plastic clay placed in the mold into a shape by rotating the rolling head and the mold containing clay in opposite directions around their own axes and moving towards each other.

[0003] In the ceramic rolling process, the scraper is responsible for scraping off the excess clay. However, whether it is manual or machine-controlled, the existing processing end stage usually directly pulls away or lifts up the scraper. When the clay used has a high water content or high plasticity, the clay has a large extension deformation and is easily deformed under stress during rolling, thereby increasing the contact adhesion between the clay and the scraper. This causes some clay to stick to the scraper when the scraper is pulled away, thereby affecting the integrity of the top surface of the formed clay and making the subsequent glaze forming uneven.

[0037] Step one, the clay B is placed in the mold A, conveyed to the rolling forming device 1 through the conveying line 2, and rolled and extruded by the rolling head 14 so that the clay B is shaped into a required product shape along the inner wall of the mold A;

[0038] Step two, the clay B is taken out of the mold A and conveyed to the first sintering device 3 through the conveying line 2 to be sintered so that the ceramic body is preliminarily solidified;

[0039] Step three, the preliminarily solidified ceramic body is conveyed to the glazing device 4 through the conveying line 2, and the body surface is covered with glaze in the glazing device 4;

[0040] Step four, then the glazed body is placed in the second sintering device 5 to sinter and solidify the glaze layer so as to form a ceramic product with a bacteriostatic and easy-to-clean surface;

[0041] Therefore, in step three, the surface glaze adopts the following scheme: 40-45 parts of sodium feldspar powder, 10-13 parts of iron lithium mica powder, 14-16 parts of calcined kaolin, 25-32 parts of quartz powder, 7-8.5 parts of calcined talc powder, 5-6 parts of titanium oxide, 3-3.6 parts of sodium silicate, 4-5 parts of rare earth oxide, 3-4 parts of high boron cake; wherein the rare earth oxide is a mixture of scandium oxide and lanthanum oxide, the mass ratio of scandium oxide to lanthanum oxide is 1: (1.25-1.35), the particle size of the sodium feldspar powder, the iron lithium mica powder and the calcined talc powder is 4000-5000 meshes, and the particle size of the calcined kaolin is 5000-6000 meshes.

[0042] In order to prevent unnecessary loose and damage of the rolled clay body in the rolling stage, in the embodiment, the machine body 11 is further movably provided with a material discharging assembly 6, which includes a scraper 61 for moving to the mold A to scrape the overflowed clay B on the mold A, and the material discharging assembly 6 includes a contact wheel 65 in transmission connection with the scraper 61, which is used to contact the mold A and rotate with the rotating mold A, and the rotating contact wheel 65 drives the scraper 61 to move away from the center of the mold A, so that the scraper 61 is laterally removed while the clay is formed, which ensures the completeness of the top surface of the formed clay, and further ensures the uniform coverage of the glaze, avoids the uneven glaze affecting the melting and leveling of the glaze, and avoids the glaze from having defects such as pinholes and bubbles.

[0043] As known, the material discharging assembly 6 needs to be movably arranged on the machine body 11, so as to be removed after the rolling operation is completed, thereby leaving space for taking away the mold A, at this time, the removal direction can be selected from the lateral direction and the vertical direction, in order to avoid occupying the lateral space and cooperate with the working direction of the rolling forming equipment 1, in the embodiment, the material discharging assembly 6 includes a mounting shell 62 and is movably arranged on the machine body 11 through a moving assembly 7, and the moving assembly 7 is in linkage cooperation with the working arm 12, the moving assembly 7 includes an output seat 76, the working arm 12 is provided with a linkage member 121 and is in contact with the moving assembly 7, when the working arm 12 swings downward, the output seat 76 of the moving assembly 7 is driven by the linkage member 121 to move downward to the mold A, and the output seat 76 drives the material discharging assembly 6 to move vertically, so that the material discharging assembly 6 moves in the vertical range.

[0044] For the moving assembly 7, the usual vertical sliding form will generate a large vertical stroke and uneven stress, therefore, in the embodiment, the swinging lifting form is adopted to make the moving assembly 7 swing on the machine body 11, the horizontal height of the moving assembly 7 after swinging upward is greater than or equal to the horizontal height of the rolling head 14 after swinging upward through the working arm 12, and the moving assembly 7 adopts a parallelogram mechanism to drive the output seat 76 to lift, the material discharging assembly 6 is provided to retain the vertical movement freedom degree under the connection of the moving assembly 7, and the movement freedom degree of the median line projection of the connecting rod swinging shaft to the horizontal direction, but the material discharging assembly 6 is in contact with the mold A through the contact wheel 65, thereby driving the scraper 61 to move, therefore, when the median line projection of the swinging shaft to the horizontal direction moves too much, the contact wheel 65 will have too large differential speed, and the scraper 61 will move too unevenly, therefore, in the embodiment, the material discharging assembly 6 is controlled to move vertically and the movement distance in the horizontal direction is less than the radius of the contact wheel 65.

[0045] To this end, the moving assembly 7 comprises a double parallelogram mechanism formed by several connecting rods for driving the output seat 76 to move vertically, which can reduce the horizontal movement of the discharging assembly 6. Specifically, the moving assembly 7 comprises a vertical seat 71, the double parallelogram mechanism comprises two front group swing arms 72 hingedly connected to the vertical seat 71, and a parallel edge connecting rod 73 is connected between the ends of the two front group swing arms 72, so that the two front group swing arms 72, the vertical seat 71 and the parallel edge connecting rod 73 form a first group of parallelogram mechanisms. A reset elastic member 78 is arranged between the front group swing arms 72 and the vertical seat 71, which provides an elastic force for driving the front group swing arms 72 to swing upward, so that the front group swing arms 72 also swing upward and reset after the working arm 12 is reset. Furthermore, the double parallelogram mechanism also comprises a rear group first swing arm 74 and a rear group second swing arm 75. The rear group first swing arm 74 has three connection points, i.e., one end, the other end and the middle part. The middle part of the rear group first swing arm 74 and one end of the rear group second swing arm 75 are hingedly connected to the ends of the two front group swing arms 72, and one end of the rear group first swing arm 74 and the rear group second swing arm 75 are hingedly connected to the output seat 76. The rear group first swing arm 74, the rear group second swing arm 75, the output seat 76 and the parallel edge connecting rod 73 form a second group of parallelogram mechanisms, and the rear group first swing arm 74 and the rear group second swing arm 74 at the ends of the front group swing arms 72 point to the direction of the vertical seat 71, so as to form an inside-out staggered state. Finally, the other end of the rear group first swing arm 74 is connected to the vertical seat 71 through a synchronous connecting rod 77. Thus, when the first group of parallelogram mechanisms moves, the second group of parallelogram mechanisms is driven to move synchronously by pulling or pushing the rear group first swing arm 74 through the synchronous connecting rod 77, so that the output seat 76 moves in a path approximately vertical to the vertical direction.

[0046] Meanwhile, the mounting shell 62 of the discharging assembly 6 is provided with a sliding member 63, which is slidingly installed on the output seat 76, and a reset pulling member 64 is arranged between the sliding member 63 and the output seat 76 to drive the sliding member 63 to reset. The sliding member 63 is initially located away from the output seat 76. After the output seat 76 is lowered following the swing, the discharging assembly 6 first contacts the mold A, and then the output seat 76 continues to descend, thereby leaving a certain amount of play, so as to ensure that the discharging assembly 6 can completely contact the mold A.

[0047] For the discharge assembly 6, the contact wheel 65 is provided with an input gear 66, the mounting shell 62 is provided with a reduction gear set 67, the scraper 61 is provided with a driving frame 69, the mounting shell 62 at the side end of the driving frame 69 is provided with an output gear 68 engaged with the driving frame 69, the output gear 68 is connected with the reduction gear set 67, the input gear 66 is connected with the driving frame 69 and the scraper 61 in transmission through the reduction gear set 67, in the embodiment, the input gear 66 is a bevel gear, the reduction gear set 67 includes a first contact gear 671, the first contact gear 671 is a bevel gear for engaging with the input gear 66, so as to convert the vertical rotation of the contact wheel 65 into the horizontal rotation of the reduction gear set 67, so as to drive the driving frame 69 to move horizontally;

[0048] It should be noted that, in order to reset the driving frame 69 after moving without working, the driving frame 69 at the rear end and the mounting shell 62 are provided with a torsion elastic element 691 for providing a reset force for the driving frame 69 and the scraper 61 to the mold A direction, and it should be noted that, in order to avoid the resistance of the reduction gear set 67 to the reset of the driving frame 69 causing the gear to be locked, the number of gears engaged in the reduction gear set 67 should be less than 4, and all are spur gears, and the influence of the input gear 66 with different rotation directions needs to be removed;

[0049] Therefore, in the embodiment, the contact wheel 65 is swingably arranged on the mounting shell 62 through the swing frame 651, the swing frame 651 drives the contact wheel 65 to swing downward to disengage the input gear 66 from the reduction gear set 67, the reduction gear set 67 further includes a synchronous driving wheel 672 and a driven wheel 673, the synchronous driving wheel 672 is coaxially connected with the first contact gear 671, the driven wheel 673 is engaged with the synchronous driving wheel 672, and the synchronous driving wheel 672 is coaxially connected with the output gear 68;

[0050] It is to be noted that in the present embodiment, the length of the scraper 61 extending into the inside of the mold A from the inside edge of the mold A is defined as L1, the length ratio of the circumference of the output gear 68 to L1 is 1:3~1:6, the process of the rolling head 14 descending to the mold A to extrude the mud B includes an extrusion stage, an overflow stage and a shaping stage, in the extrusion stage, the rolling head 14 extrudes the mud B to make the mud B adhere to the inner wall of the mold A, the overflow stage is that the excess mud B overflows from the edge of the mold A, and the shaping stage is a few idle strokes after the scraper 61 separates the overflowed mud B; the scraper 61 moving away from the center of the mold A is located inside the edge of the mold A in the overflow stage and the shaping stage, and the overflow stage and the shaping stage usually perform 3-6 strokes, therefore, the length ratio of the path length of the contact wheel 65 walking one circle on the mold A to the circumference length of the contact wheel 65 is 8:1~12:1, and the transmission ratio of the contact wheel 65 to the output gear 68 is 12:1~8:1, so that when the mold A rotates one circle, the output gear 68 also rotates nearly one circle, and the scraper 61 moves outward from the mold A by 3-6 units, and the unit number is determined according to the number of rotations of the mold A in the overflow stage and the shaping stage.

[0051] Meanwhile, the driving frame 69 includes a strip structure and is connected to the scraper 61 extending downward, the mounting shell 62 is provided with a sliding seat 621, the strip structure of the driving frame 69 is slidingly arranged in the sliding seat 621, the side of the sliding seat 621 facing the output gear 68 is provided with a movable port 622, the output gear 68 is provided with a driving tooth 68a, the strip structure is provided with a tooth step 69a with a thickness smaller than the diameter of the strip structure, the tooth step 69a extends from the movable port 622 and is provided with a driven tooth 69b for engaging with the driving tooth 68a, so as to rotate the output gear 68 to drive the driving frame 69 to move, and the driving frame 69 synchronously drives the scraper 61 to move.

[0052] In summary, in the first step, the working arm 12 swings downward and drives the front group swing arm 72 of the moving assembly 7 to swing downward in the direction of the mold A, the first group of parallelogram mechanisms swings downward, the second group of parallelogram mechanisms is driven to swing downward synchronously by the synchronous connecting rod 77, the output seat 76 is driven to move in a path approximately vertical to the vertical, the contact wheel 65 of the discharging assembly 6 contacts the mold A, the downward contact wheel 65 is driven to swing upward by the swing frame 651 to make the input gear 66 mesh with the first contact gear 671, the mold A rotates 4 turns in the overflow stage, the mud B overflows at the edge of the rotating mold A, the rotating mud B flies after contacting the scraper 61, the machine body 11 is also provided with a collecting bin 16 for collecting the overflowed and flown mud B, the contact wheel 65 is driven to rotate by the mold A, the contact wheel 65 drives the output gear 68 to rotate through the reduction gear set 67, the output gear 68 meshes with the driving frame 69 and rotates nearly 1 turn when the mold A rotates 1 turn, the scraper 61 moves outward from the mold A by 4 units, the mold A rotates 2 turns in the shaping stage, the scraper 61 moves outward from the mold A by 2 units and L1 is less than 0 at this time, the scraper 61 moves out of the mold A, and the mud B is also shaped in the mold A, the top of the shaped mud B is not covered by the blade and the scraper 61, avoiding the influence of the sudden lifting of the scraper 61 on the top surface shaping quality.

[0053] In addition, in the embodiment, the distance between the upper edge and the lower edge of the movable opening 622 is greater than the thickness of the tooth step 69a, thereby providing space for the downward swinging of the strip structure, the output gear 68 as the driving structure makes the strip structure of the driving frame 69 have a downward rotating trend around the axis during the movement of the driving frame 69 to the compressed torsion elastic member 691, the downward rotating scraper 61 has a gap with the top surface of the mold A before rotating, which is an objective gap and does not affect the molding effect, but in the embodiment, the downward rotating scraper 61 is in close contact with the top surface of the mold A.

[0054] Therefore, the bottom end of the driven tooth 69b extends to form an inclined driven tooth 69c inclined to the mold A, the torsion elastic member 691 applies a torsion force to the strip structure of the driving frame 69 to rotate upward around the axis; the output gear 68 as the driving structure makes the strip structure of the driving frame 69 rotate downward by overcoming the torsion force of the torsion elastic member 691 during the movement of the driving frame 69 to the compressed torsion elastic member 691, so that the scraper 61 is in close contact with the top surface of the mold A, ensuring the stability of the working position of the scraper 61, after the contact wheel 65 is separated from the mold A, the reduction gear set 67 loses power, the driving frame 69 is driven by the torsion elastic member 691 as the driving structure to rotate the output gear 68, during which the strip structure of the driving frame 69 is driven by the torsion elastic member 691 to rotate upward to reset.
