Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ceramic body roll forming, in particular to a ceramic body roll forming device capable of continuously rotating and discharging. BACKGROUND

[0002] The ceramic body roll forming is a common ceramic forming process, mainly used for producing circular or axisymmetric ceramic products (such as bowls, plates, cups, jars and the like), and the technical core is to uniformly press the clay into the required body shape through the cooperation of a rotating mold and a roll head.

[0003] The rotating mold cooperates with the roll head, the mold (female mold) is usually a gypsum mold or a metal mold with the shape of the target body inner cavity, and is fixed on a rotating workbench; the roll head (male mold) is a roll tool matched with the mold shape, and is used for uniformly extending the clay to the inner wall of the mold through pressure to form a body; the mold and the roll head are synchronously rotated (in the same direction or in opposite directions) to uniformly distribute the clay by using centrifugal force and mechanical pressure; the clay is placed in the mold, and finally the body consistent with the inner cavity of the mold is formed, and then the body is demolded and dried.

[0004] As for the design of the roll head system, the roll head is usually made of wear-resistant metal (such as stainless steel) or covered with elastic material (such as rubber), and the down pressure of the roll head is controlled by a hydraulic or pneumatic system; for example, the patent with the publication number CN208163923U discloses a new roll head for ceramic body roll forming, which drives the entire slide to rotate by means of a lower roll upper cam and a rear pull cam, and presses the upper roll main shaft with the upper roll head into the top mold disc to complete the roll forming of the body, but the formed body needs to be discharged after the entire head is reset and the formed body is taken out, and the roll head is in the idle state at this time, which reduces the ceramic forming efficiency; therefore, the application provides the ceramic body roll forming device capable of continuously rotating and discharging. SUMMARY

[0010] Further, the sliding base plate top and located in the fixed connection with the support in the rotating shaft one, and the support one end penetrates the rotating disc and is fixedly connected with the positioning disc, the rolling frame side wall top is fixed with the clamp cover through the bolt, the drive assembly is installed in the clamp cover, the male die is installed on the drive assembly output end, the rolling frame other side is fixedly connected with the air cylinder, the air cylinder end is fixedly connected with the alternating suction disc assembly.

[0011] Further, the sliding base plate top is fixedly connected with the positioning frame, the positioning frame both sides channel is movably connected with the tooth plate one and the tooth plate two, the drive gear is movably connected in the positioning frame, and the tooth plate one and the tooth plate two opposite side are meshed with the drive gear both sides.

[0012] Further, the sliding base plate top and located in the fixed connection with the support in the rotating shaft one, and the support one end penetrates the rotating disc and is fixedly connected with the positioning disc, the rolling frame side wall top is fixed with the clamp cover through the bolt, the drive assembly is installed in the clamp cover, the male die is installed on the drive assembly output end, the rolling frame other side is fixedly connected with the air cylinder, the air cylinder end is fixedly connected with the alternating suction disc assembly.

[0013] Further, the rotating disc is fixedly connected with the mold storage cylinder, and the mold storage cylinder is movably connected with the female die, and the female die is movably connected with the abutting sleeve.

[0014] The continuous rotation discharging ceramic body rolling forming method is:

[0015] The passive abutting forming is carried out, the male die position of the drive assembly end on the rolling frame is fixed, the sliding base plate on the horizontal drive table and the vertical drive table is controlled to move, so that the positioning disc side rolling area corresponds to the male die, and then the female die is fixedly installed in the mold storage cylinder on the rotating disc;

[0016] As the ceramic blank is cut and placed in the female mold, the mold storage cylinder with the blank is moved to the bottom of the rolling area on the positioning plate side by rotating the shaft 120 degrees. As the arc-shaped chuck continues to rotate, the cams at the two ends of the rotating shaft press down the U-shaped tilting rod, causing the tooth plate in the positioning frame on the other side to move down, pushing the abutment sleeves on both sides of the tooth plate to move up, and pushing the abutment sleeves in the mold storage cylinder upward, causing the female mold with the ceramic blank to contact the male mold at the end of the driving assembly. The driving groove disk rotates to drive the convex disk and the abutment sleeve to rotate, realizing the rotation of the female mold, and the driving assembly drives the male mold to rotate to complete the rolling of the ceramic blank.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention realizes continuous rolling production of ceramic green bodies, and significantly improves efficiency. The 120° intermittent rotation design of the turntable realizes the cyclic switching of the three stations of green body adding, rolling forming, and unloading, eliminating the idle period of stopping the machine to take out the green body in the traditional process. Compared with the existing technology, the efficiency of ceramic green body rolling forming is improved by 20%, and uninterrupted continuous production is achieved. At the same time, it is different from the traditional downward pressure contact rolling forming. A mechanical linkage mechanism is adopted. The cam, U-shaped tilting rod, and tooth plate automatically control the lifting and rotation of the female mold, and cooperate with the drive assembly to drive the male mold to rotate synchronously, ensuring the rolling accuracy while further improving the molding efficiency. The unloading station drives the alternating suction cup assembly through the cylinder to automatically adsorb the molded green body. No manual operation is required throughout the process, reducing labor intensity.

[0020] 2. In the present invention, the forming quality of the blank is improved and deformation of the blank is avoided. The linkage design of the female mold and the abutment sleeve, combined with the precise driving of the convex disk by the driving groove disk, ensures that the rotation speed of the female mold and the male mold matches, avoiding deformation or eccentricity of the blank due to the rotation speed difference. The scraper arranged on the side of the positioning disk can synchronously remove the edge waste, further ensuring the surface smoothness of the blank. At the same time, the horizontal drive platform and the vertical drive platform cooperate to control the position of the sliding base plate to realize the rapid alignment of the mold and the rolling head. The drive component can adjust the angle and pressure of the male mold to adapt to the production needs of ceramic products of different specifications, and has strong scalability.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-7 , the present invention provides a technical solution:

[0031] Regarding the rolling forming of porcelain blanks, the present invention adopts a passive upward push method, actively pushing the mold with the blank upward to contact the rolling head in a fixed position, and automatically changing position after the blank is formed. Compared with the method of pressing the rolling head downward to contact the blank, the efficiency of porcelain blank rolling forming is improved by 20%;

[0032] like Figure 1 As shown, the horizontal drive platform 2 and the vertical drive platform 3 are installed on the rolling frame 1, and the sliding base plate 4 is installed on the vertical drive platform 3. The vertical drive platform 3 moves to control the position of the entire sliding base plate 4 on the rolling frame 1. For the specific position adjustment of the sliding base plate 4, the specific coordinates can be set according to the movement principle of conventional cutting machine tools.

[0033] The top of the sliding base plate 4 is provided with two layers of plates, namely the turntable 8 and the positioning plate 14. The turntable 8 is driven to rotate by the rotating shaft 7. The rotating shaft 7 is hollow and has a support column extending from the inside thereof connected to the top positioning plate 14. That is, the turntable 8 can rotate while the entire positioning plate 14 remains stationary.

[0034] The holes on the entire positioning plate 14 are matched with the mold storage cylinder 9 on the bottom turntable 8, such as Figure 7 As shown, it is divided into a passive rolling area, a forming and demoulding area and a blank adding area, wherein the passive rolling area corresponds to the male mold 26 installed on the rolling frame 1, and the forming and demoulding area is responsible for taking out the rolled porcelain blank. Finally, the blank adding area is provided with a discharge robot arm to automatically place the sheared raw materials into the corresponding mold;

[0035] Since the rotating shaft 7 drives the turntable 8 to rotate, and the corresponding mold storage cylinder 9 needs to be moved to the corresponding area, a special rotating drive mechanism is set for this purpose, such as Figure 4 As shown, a hemispherical disk shell 15 is fixedly mounted on the rotating shaft 1 7, and a second rotating shaft 16 is provided on the driving side. The rotating shaft 16 is driven by the motor at the bottom of the sliding base plate 4. An arc-shaped chuck 18 is fixedly mounted on the second rotating shaft 16. The arc-shaped chuck 18 is divided into two parts, the upper part is an arc block, and the lower part is a hook block, which corresponds to the entire hemispherical disk shell 15.

[0036] When the entire second rotating shaft 16 rotates, the hook block on the arc chuck 18 contacts the deep arc cut on the hemispherical shell 15, driving the entire hemispherical shell 15 to rotate 120 degrees. Subsequently, the arc block on the arc chuck 18 contacts the shallow arc cut on the hemispherical shell 15. The second rotating shaft 16 rotates on its own without driving the entire first rotating shaft 7 to rotate.

[0037] Returning to the entire rotation path of the rotating shaft 7, it first rotates 120 degrees and then stops for a period of time, so that the turntable 8 on the top of the rotating shaft 7 rotates at a fixed angle, and the mold storage cylinder 9 is moved to the corresponding working area on the positioning disk 14. Similarly, the blank adding area will finish feeding the material, and after 120 degrees of rotation, the blank will be moved to the passive rolling area, and the molding material in the passive rolling area will be moved to the molding demolding area. This cycle is repeated to improve the overall rolling efficiency of the ceramic body.

[0038] Since the mold storage cylinder 9 at the top of the turntable 8 is located at the bottom of the positioning disk 14, and the male mold 26 at the end of the drive assembly 25 is located at the top of the positioning disk 14, the female mold 10 in the mold storage cylinder 9 cannot achieve contact between the blank and the male mold 26. Figure 4 As shown, a cam 17 is also sleeved and mounted on the second rotating shaft 16, and a U-shaped tilting rod 19 is rotatably connected to the sliding base plate 4 on the side of the cam 17. The U-shaped tilting rod 19 contacts the cam 17, and as the cam 17 rotates, one side is squeezed and tilted up, and the squeezed side rotates and descends. A positioning frame 20 is fixed on the other side of the top of the sliding base plate 4;

[0039] The two sides of the positioning frame 20 are respectively connected in a sliding manner with a tooth plate 1 22 and a tooth plate 2 23. Under normal conditions, the weight of the tooth plate 23 is greater than that of the tooth plate 1 22 and the storage height is less than that of the tooth plate 1 22. A convex column is set on one side of the tooth plate 23, such as Figure 3 and Figure 6 As shown, an abutment sleeve 11 is installed in the mold storage cylinder 9, one end of the abutment sleeve 11 passes through the mold storage cylinder 9 and is sleeved with a snap ring. The abutment sleeve 11 should be clamped in the mold storage cylinder 9, and the storage position is fixed. As the turntable 8 rotates, the side of the abutment sleeve 11 with the snap ring is moved to the side of the positioning frame 20 on the top of the sliding base plate 4, causing the protrusion on the tooth plate 23 on the side of the positioning frame 20 to be fixedly contacted with the snap ring. Therefore, the upward movement of the tooth plate 23 can push the abutment sleeve 11 to move in the mold storage cylinder 9;

[0040] The female mold 10 is installed in the mold storage cylinder 9 and is clamped with the top of the abutment sleeve 11 in the mold storage cylinder 9. Therefore, the rotation of the abutment sleeve 11 can also realize the rotation of the female mold 10. The height adjustment of the abutment sleeve 11 indirectly promotes the movement of the female mold 10. By utilizing this, a U-shaped tilting rod 19 is connected to the cam 17 on the sliding base 4;

[0041] When the arc block on the entire arc chuck 18 contacts the shallow arc cutout of the hemispherical disk shell 15, the cam 17 at this time contacts the end of the U-shaped tilting rod 19, pressing down to cause the other side of the U-shaped tilting rod 19 to move downward and rotate synchronously, and the other side of the U-shaped tilting rod 19 is located above the tooth plate 1 22, synchronously pushing the entire tooth plate 1 22 down, and the tooth plate 1 22 and the tooth plate 2 23 are meshed and connected by the driving teeth 21 in the positioning frame 20. The tooth plate 1 22 descends and the tooth plate 2 23 rises, pushing the entire tooth plate 2 23 and the side wall abutment sleeve 11 to rise synchronously, causing the female mold 10 at the end of the abutment sleeve 11 to rise, gradually move through the positioning disk 14 and drive the blank to contact the male mold 26;

[0042] At this time, the driving assembly 25 drives the male mold 26 to rotate and the female mold 10 to rotate synchronously, so that the blank can be roll-formed in the mold. Correspondingly, the positioning plate 14 is also provided with a scraper on the side of the rolling working area to scrape off the edge waste generated by the roll forming. The entire driving assembly 25 is fixed on the clamping cover 24, and the position and deflection angle can be adjusted with a high degree of freedom.

[0043] To ensure that the rolling head and the mold rotation speed match, the abutment sleeve 11 at the bottom of the female mold 10 also needs to rotate, such as Figure 3 As shown, the bottom of the abutment sleeve 11 is slidably connected to a rotating rod 12, as shown in FIG. Figure 5 and Figure 6As shown, the bottom of the rotating rod 12 is also fixed with a convex disc 13, and a limiting groove 5 is opened on the sliding base plate 4 corresponding to the convex disc 13, the whole limiting groove 5 is provided with a special circular channel in the passive rolling area, a driving groove disc 6 is movably connected in the limiting groove 5 and on the sliding base plate 4, and a transverse groove is arranged on the top of the driving groove disc 6 and is matched with the overall arc-shaped groove of the limiting groove 5;

[0044] With the rotation of the rotating disc 8, the bottom convex disc 13 on the mold storage cylinder 9 is continuously slid in the limiting groove 5, when the convex disc 13 moves to the passive rolling area, at this time, the two protrusions on the bottom of the convex disc 13 contact the groove on the driving groove disc 6, and under the directional rotation of the rotating disc 8, the two protrusions on the convex disc 13 and the straight groove on the driving groove disc 6 are connected in a straight line, at this time, the rotation of the driving groove disc 6 can drive the rotation of the convex disc 13, and the abutting sleeve 11 connected thereto and the female mold 10 on the abutting sleeve 11 also start to rotate, cooperate with the rotation of the top male mold 26, and the rolling head and the mold rotation speed are matched to avoid the deformation of the blank, and finally form a blank consistent with the inner cavity of the mold, and then demold and dry;

[0045] After the blank is formed, the raw material in the subsequent mold storage cylinder 9 is continuously supplemented, and for the formed blank, an automatic unloading mechanism is also arranged on the rolling frame 1, which uses a suction cup assembly to grab and unload, and before unloading, considering that the structure of the just-formed blank is unstable, direct grabbing can easily cause deformation of the blank, an auxiliary drying assembly can be installed in the unloading area to heat and shape the entire formed blank, and then the formed blank is grabbed and unloaded by the alternating suction cup assembly 28 installed on the side of the cylinder 27, which facilitates the continuous work of the ceramic blank rolling forming device.

[0046] The above content is only an example and description of the structure of the present application, and those skilled in the art can make various modifications or supplements or use similar ways to replace the described specific embodiments, as long as they do not deviate from the structure of the present application or exceed the scope defined by the present claims, which shall belong to the protection scope of the present application.
