Description

Technical Field

[0001] The present invention relates to the technical field of ceramic processing, and particularly to a ceramic rolling forming device. Background Art

[0002] Rolling forming is an efficient modern forming process. It uses a rotating forming die and a rolling die to apply uniform pressure to the clay blank, causing the clay blank to gradually become dense inside the die and finally form the desired shape. However, the connection between the formed clay blank and the inner wall of the forming die is relatively tight. To reduce the breakage rate when removing the formed clay blank, in actual operation, the formed clay blank and the die are taken out together, and the clay blank is waited to be partially cured before separation. This step means that each formed clay blank needs to occupy a die until it is cured, resulting in a relatively long cycle of the die.

[0003] In a ceramic production line, since the die cannot be reused immediately, a large number of dies are required to meet the continuous production demand. This not only increases the purchase cost of the forming die but also occupies a large amount of storage space. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Embodiment 1: Reference Figures 1-5 , a ceramic rolling forming device, comprising a rotating base 1, a forming die 2, a rolling assembly 3, an ejecting assembly 4 and a locking assembly 5, and a mud collecting assembly 6 can be selectively provided. Each assembly cooperates with each other to jointly complete the rolling forming of ceramic products. The rotating base 1 is the basic supporting component of the whole device, including a fixed seat and a rotating seat, which is the prior art and will not be elaborated here. A placing groove 11 can be provided in the middle of the rotating seat, and the forming die 2 can be coaxially placed in the placing groove 11. The forming die 2 contains and forms the green body, which can realize the stable installation of the forming die 2. The rotating seat can be rotated by a driving device such as a motor to drive the forming die 2 to rotate synchronously for rolling forming operations. The rolling assembly 3 is arranged on the top of the rotating base 1 and is used in cooperation with the forming die 2 to apply uniform pressure to the green body to complete the rolling forming operation of the ceramic green body. The ejecting assembly 4 is arranged in the placing groove 11 and at the bottom of the forming die 2, and can smoothly and safely eject the formed ceramic product from the forming die 2 to realize the separation of the formed green body from the forming die 2, so as to realize the reuse of the forming die 2, shorten the cycle period of the forming die 2, reduce the number of forming dies 2, and reduce the production cost and storage space requirements. The locking assembly 5 is arranged on the rotating base 1 and can lock the forming die 2 on the rotating base 1 to ensure the stability of the forming die 2 during the rolling process, thereby improving the quality of the formed green body.

[0025] In some embodiments, the molding die 2 includes a molding ring 21 and a molding disc 22. The molding ring 21 is coaxially arranged in the placement groove 11 and can define the outer shape of the molded green body. The molding disc 22 is coaxially arranged in the molding ring 21 and is fixedly connected to the ejection assembly 4. The molding disc 22 can support the green body to be molded. The molding disc 22 can slide vertically in the molding ring 21. When the molding disc 22 cooperates with the molding ring 21 and the rolling die 33, a rolling cavity for the green body can be formed, so that the green body is rolled into the required shape in the rolling cavity. The cross-sections of the molding ring 21 and the molding disc 22 can both be isosceles trapezoids. The design with an upward slope can change the height of the molding ring 21 in the molding disc 22, thereby changing the gap between the outer wall of the molding ring 21 and the inner wall of the molding disc 22, thereby improving the sealing performance of the molding disc 22 covering the molding ring 21, facilitating the ejection of the molded green body, reducing the difficulty of separating the molded green body from the inner wall of the molding ring 21, and improving the integrity of the molded green body after ejection.

[0026] In some embodiments, the rolling assembly 3 includes a fixed frame 31, a rotating frame 32, a rotating motor, and a rolling die 33. The fixed frame 31 is fixedly connected to one end of the top of the rotating base 1, which can provide a stable and reliable support for the installation and operation of subsequent components, ensuring the position accuracy and stability of each component during the rolling process. The rotating frame 32 is rotatably connected to the fixed frame 31 and can rotate around a fixed point. The rotating motor is connected to the rotating frame 32. When the rotating motor is started, it can drive the rotating frame 32 to rotate, thereby adjusting the position and angle of the rolling die 33, realizing the insertion and separation of the rolling die 33 in the placement groove 11. The rolling die 33 is rotatably connected to the bottom of the rotating frame 32, and the rolling die 33 is in contact with the molding die 2 through the green body. A rolling motor is connected to the rolling die 33. Driven by the rolling motor, the rolling die 33 starts to rotate. During the rotation of the rolling die 33, pressure and friction are applied to the green body, and it cooperates with the molding die 2 to gradually compact the green body and roll the green body into the required shape, realizing the molding operation of the molded green body.

[0027] In some embodiments, the rolling assembly 3 further includes a rotatable edge pressing wheel 34. The edge pressing wheel 34 is arranged on one side of the rolling die 33 and can be connected to the bottom of the rotating frame 32 through a fixed shaft. The edge pressing wheel 34 and the fixed shaft can be connected through a bearing, so that the edge pressing wheel 34 is in contact with the green body. When the green body is thrown to the edge of the molding die 2 by centripetal force, the edge pressing wheel 34 is forced to rotate. Through the rotation of the edge pressing wheel 34, the impact force of the green body can be consumed, thereby suppressing the upward movement trend of the green body, ensuring that the excess green body enters the gap between the edge pressing wheel 34 and the top surface of the molding die 2, ensuring the edge shape of the molded green body. At the same time, the rotating edge pressing wheel 34 can improve the uniformity of the force applied by the edge pressing wheel 34 to the green body, ensuring the molding of the excess green body at the edge.

[0028] The gap between the wheel surface of the edge pressing wheel 34 and the top surface of the forming mold 2 is precisely calculated to ensure that the edge of the clay blank can be leveled during the rolling process while avoiding excessive extrusion. The edge pressing wheel 34 is fixed on the fixed frame 31, and the clay blank is pressed between the edge pressing wheel 34 and the top surface of the forming mold 2. During the rolling process, the edge pressing wheel 34 compacts and shapes the edge of the clay blank, which can improve the edge quality of the formed clay blank, avoid problems such as uneven edges and uneven thickness, and make the final formed ceramic products more beautiful and meet quality standards; at the same time, through the edge pressing effect of the edge pressing wheel 34, the inner high edge structure of the formed clay blank can be formed between the edge pressing wheel 34 and the rolling mold 33, so that the inner high edge structure is formed in one piece, avoiding the operation of sharpening the blank in the later stage, reducing the operation steps in the forming process, and improving the forming speed of the inner high edge forming clay blank.

[0029] In some embodiments, the locking assembly 5 includes a fixed ring 51, a plurality of mounting blocks 52, a rotating rod 53, a rotating hammer 54 and a locking claw 55. The fixed ring 51 is mounted on the rotating seat of the rotating base 1 and can be welded and fixed. The various parts of the locking assembly 5 can be tightly connected with the rotating seat to provide a stable foundation for the subsequent locking action. The plurality of mounting blocks 52 are arranged on the fixed ring 51 at equal intervals. The mounting blocks 52 can be fixed blocks with openings. The mounting blocks 52 provide a precise installation position for the rotating rod 53 to ensure that the rotating rod 53 can be accurately installed on the fixed ring 51 and can rotate smoothly. The mounting blocks 52 can be six to ensure uniform distribution of the locking force. The rotating rod 53 is hinged on the mounting blocks 52 so that it can rotate freely around the hinge point. The rotating hammer 54 is arranged at the bottom of the rotating rod 53. When the rotating seat starts to rotate, the rotating hammer 54 will generate an outward centrifugal force due to its own mass and rotational motion. According to the principles of physics, the magnitude of the centrifugal force is related to the rotation speed and the mass of the rotating hammer 54. As the rotation speed increases, the centrifugal force generated by the rotating hammer 54 will also increase accordingly. This centrifugal force will drive the rotating rod 53 to rotate around the hinge point while following the rotation of the rotating seat, providing a power source for the subsequent locking action. The locking claw 55 is arranged on the top of the rotating rod 53 and can rotate freely around the rotating shaft 57. The locking claw 55 can be buckled on the top of the forming mold 2 to achieve the locking of the mold. This avoids the problems of reduced shape accuracy and dimensional deviation caused by the unstable fixation of the forming mold 2, displacement or shaking.

[0030] In some embodiments, the locking assembly 5 further includes a rotating groove 56, a rotating shaft 57, and a torsion spring. The rotating groove 56 is provided at the top of the rotating rod 53. The rotating shaft 57 is fixedly provided in the rotating groove 56, and a rotatable locking claw 55 is sleeved on the rotating shaft 57. The rotating shaft 57 can provide support and an axis for the rotation of the locking claw 55. The torsion spring is provided between the rotating shaft 57 and the locking claw 55, and the torsion spring can provide a certain amount of torsion to provide an automatic reset force for the locking claw 55. In the normal state, the torsion of the torsion spring keeps the locking claw 55 in a specific position. When the rotating rod 53 rotates under the centrifugal force generated by the rotating hammer 54, it will drive the locking claw 55 to move together. When it rotates to a suitable position, the locking claw 55 will buckle on the top of the forming die 2, thereby realizing a firm lock of the forming die 2, ensuring that the forming die 2 will not be displaced or shaken during the rolling process, and thus improving the stability and convenience of locking. The locking claw 55 can be an L-shaped block, and a rubber block is provided on the bottom surface of the locking claw 55 that buckles on the top of the forming die 2. The rubber block can increase the friction between the locking claw 55 and the forming die 2, thereby enhancing the locking force of the locking claw 55 on the forming die 2.

[0031] In some embodiments, a mud collecting assembly 6 is further included, which can timely process the excess mud generated during the rolling process, ensure the appearance quality of the ceramic product, and at the same time recycle the excess mud to avoid environmental pollution. The mud collecting assembly 6 includes a mud collecting cover 61 and a mud collecting knife 62. The mud collecting cover 61 is obliquely provided on the side of the pressing wheel 34 away from the rolling die 33, and can guide and collect the excess mud generated during the rolling process. When the mud is scraped off, it will slide down along the inclined surface of the mud collecting cover 61, which is convenient for centralized collection and cleaning, and improves the efficiency of mud collection and discharge. The mud collecting knife 62 is provided at the bottom of the opening of the mud collecting cover 61, and the bottom of the mud collecting knife 62 is closely attached to the top surface of the forming die 2. During the rolling process, the mud collecting knife 62 can accurately scrape off the excess mud on the top surface of the forming die 2 and make it fall into the mud collecting cover 61. In this way, the excess mud is prevented from remaining on the formed green body, ensuring the cleanliness and smoothness of the surface of the ceramic product, reducing the subsequent operations of the formed green body, and improving the production efficiency.

[0032] In some embodiments, the ejection assembly 4 includes a lifting groove 41, a lifting plate 42, a plurality of sliding grooves 45, an ejector 43, and a connecting rod 44. The lifting groove 41 is coaxially provided at the bottom of the placement groove 11, which can provide a specific movement range for the movement of the lifting plate 42 and the ejector 43, ensuring accurate movement, avoiding deviation or jamming, and guaranteeing the smooth progress of the ejection process. The lifting plate 42 is coaxially arranged in the lifting groove 41 and can be lifted in the lifting groove 41. By the rising and falling of the lifting plate 42, the subsequent formed green body is ejected. The plurality of sliding grooves 45 are annularly arranged on the inner wall of the lifting groove 41 for installing the ejector. The sliding groove 45 can provide a running path for the sliding of the ejector 43, ensuring that the ejector 43 can slide along a predetermined path and guaranteeing the accuracy and stability of the ejection action. The ejector 43 is slidably arranged in the sliding groove 45. The top end of the connecting rod 44 is hinged to the bottom of the lifting plate 42, and the bottom end of the connecting rod 44 is hinged to the ejector 43. The sliding groove 45 can be obliquely upwardly arranged, facilitating the sliding of the ejector 43 in the sliding groove 45 under its own gravity when the rotating seat is stationary, realizing reset. The ejector 43 includes a slide rod 431 and a slider 432. The slide rod 431 can freely slide in the sliding groove 45, and one end of the slide rod 431 close to the lifting groove 41 is hinged to the connecting rod 44. The slider 432 is slidably arranged in the sliding groove 45 and is fixedly connected to the slide rod 431. By the sliding of the slider 432 in the sliding groove 45, the ejection of the formed green body and the formation of the forming cavity are realized. The slider 432 can be a spherical ball, which can reduce the friction between the slider 432 and the inner wall of the sliding groove 45, thereby reducing the resistance when the slider 432 slides.

[0033] Specifically, when the slider 432 is in the initial state, the lifting plate 42 is located in the placement groove 11, and there is a gap between the bottom of the lifting plate 42 and the bottom of the forming ring 21. When rolling is required, the rotating seat on the base 1 rotates, and the slider 432 rotates along with it. During the rotation process, a centrifugal force is generated. Under the action of this centrifugal force, the slider 432 slides in the sliding groove 45 away from the lifting groove 41, and the connecting rod 44 will change its angle along with the movement of the slider 432. Since the top end of the connecting rod 44 is hinged to the bottom of the lifting plate 42 and the bottom end is hinged to the ejector 43, the angle change of the connecting rod 44 will drive the lifting plate 42 to descend in the lifting groove 41, thereby driving the forming plate 22 to descend, covering the bottom of the forming ring 21. The rolling die 33 extends into the placement groove 11 and jointly forms a rolling cavity with the forming plate 22 and the forming ring 21. The green body is rolled into a corresponding shape in this rolling cavity. After rolling forming, the rolling die 33 is withdrawn, and the rotating seat slowly stops rotating. During this process, the centrifugal force generated by the rotation of the slider 432 gradually decreases, so that the slider 432 gradually slides towards the lifting groove 41. Similarly, through the hinged action of the connecting rod 44, the lifting plate 42 is lifted, thereby driving the forming plate 22 to rise and reset. During the rising process of the forming plate 22, the formed green body is driven to rise, thereby realizing the separation of the formed green body from the forming ring 21, facilitating the removal of the formed green body, shortening the cycle period of the forming die 2, reducing the number of forming dies 2, and reducing the production cost and the storage space requirement.

[0034] In some embodiments, a plurality of guiding grooves are annularly provided on the inner wall of the lifting groove 41, the guiding grooves are vertically arranged, guiding strips adapted to the shapes of the guiding grooves are provided on the side wall of the lifting plate 42, the guiding strips are inserted and matched with the guiding grooves, and the guiding strips can slide in the guiding grooves. By sliding the guiding strips in the guiding grooves, the sliding path of the lifting plate 42 in the lifting groove 41 can be guided, thereby improving the stability of the lifting plate 42 during the lifting process. A plurality of guiding wheels can be provided on the inner walls on both sides of the guiding grooves, and the guiding wheels are in rolling connection with the surface of the guiding strips, which can reduce the friction between the guiding strips and the guiding grooves, thereby reducing the energy consumption during the ejection process and ensuring the smooth ejection of the formed green body.

[0035] In some embodiments, the ejector 43 further includes an ejector spring 433 disposed between the inner wall of the sliding groove 45 and the slider 432. The ejector spring 433 functions to buffer and reset. When the ejector 43 is subjected to centrifugal force, the ejector spring 433 will undergo elastic deformation, absorbing and dispersing the impact force, enhancing the stability of the descent of the forming disk 22; when the centrifugal force disappears, the ejector spring 433 will return to its original state, driving the ejector 43 to reset, enhancing the stability of the ejection process. At the same time, through the buffering of the ejector spring 433, the instantaneous impact of the ejector 43 on the formed green body can be avoided, enabling the slow separation of the formed green body from the forming ring 21, ensuring the smoothness of the ejection process, protecting the formed green body from damage, and enhancing the integrity of the formed green body when it is taken out, thereby improving production efficiency.

[0036] The specific working principle is as follows: During specific rolling forming, first, the cut green body is placed on the forming disk 22 of the forming die 2, and the driving device of the rotating base 1 is started to make the rotating seat rotate, thereby driving the forming die 2 to start rotating. As the rotating seat rotates, the rotating hammer 54 of the locking assembly 5 rotates along with it, and a centrifugal force acting outward is generated during the rotation process, causing the rotating hammer 54 to swing away from the rotating base 1. The swinging of the rotating hammer 54 drives the swinging of the rotating rod 53, causing the locking claw 55 at the top of the rotating rod 53 to swing towards the forming die 2, thereby fastening to the top of the forming die 2. The combined action of multiple locking claws 55 realizes the locking of the forming die 2.

[0037] When the rotating seat rotates, the slider 432 rotates along with the rotating seat. During the rotation process, a centrifugal force is generated. Under the action of this centrifugal force, the slider 432 slides in the sliding groove 45 away from the lifting groove 41. The connecting rod 44 will change its angle along with the movement of the slider 432. Since the top end of the connecting rod 44 is hinged to the bottom of the lifting disk 42 and the bottom end is hinged to the ejector 43, the angle change of the connecting rod 44 will drive the lifting disk 42 to descend in the lifting groove 41, thereby driving the forming disk 22 loaded with the green body to descend. The descent of the forming disk 22 will cover the bottom of the forming ring 21.

[0038] Start the rotating motor and the rolling motor simultaneously. The rolling motor drives the rolling die 33 to rotate, and the rotating motor drives the rotating frame 32 to rotate along a set trajectory, adjusting the position and angle of the rolling die 33 so that the rolling die 33 extends into the placement groove 11, jointly forming a rolling cavity with the forming disk 22 and the forming ring 21, and contacting the green body on the forming die 2. The green body is subjected to the force between the rolling die 33, the forming disk 22, and the forming ring 21 within this rolling cavity, and under the centrifugal force, it deforms, moves, and continuously densifies, being rolled into the corresponding shape. During this process, the green body that is thrown to the top of the forming ring 21 by the centrifugal force will be compacted and shaped under the action of the edge pressing wheel 34. The green body away from the edge pressing wheel 34 will be scraped out by the mud scraping knife 62. The scraped green body will enter the mud collecting cover 61 under the inertia of rotation, realizing the collection of excess green body.

[0039] After the formed green body is roll-formed, the rotating motor drives the rotating frame 32 to rotate along a set trajectory, adjusting the position and angle of the rolling die 33 so that the rolling die 33 is withdrawn from the placement groove 11, and the rolling motor stops rotating. After the rolling die 33 is withdrawn, the rotating seat slowly stops rotating. During this process, the centrifugal force generated by the rotation of the slider 432 gradually decreases, causing the slider 432 to gradually slide towards the direction close to the lifting groove 41. Similarly, through the hinge action of the connecting rod 44, the lifting disk 42 rises, thereby driving the forming disk 22 to rise and reset. During the rising process of the forming disk 22, it will drive the formed green body to rise, realizing the ejection of the formed green body from the forming die 2, thus realizing the separation of the formed green body from the forming ring 21, facilitating the removal of the formed green body, and further shortening the cycle period of the forming die 2, reducing the number of forming dies 2, and lowering the production cost and the storage space requirement.

[0040] Meanwhile, the rotating seat stops rotating, and the centrifugal force generated by the rotation of the rotating hammer 54 disappears. Under the action of the torsion spring, the locking claw 55 releases the locking of the forming die 2, and the rotating hammer 54 returns to its original position under its own gravity.

[0041] After taking out the ejected formed green body from the forming die 2, the next forming operation can be carried out, realizing the efficient and continuous production of the formed green body.

[0042] Embodiment 2: Refer to Figure 6 In this embodiment, the difference from Embodiment 1 is that the ejecting member 43 includes a sliding rod 431. The sliding rod 431 is slidably disposed in the sliding groove 45. One end of the sliding rod 431 close to the lifting groove 41 is hinged to the connecting rod 44, and the other end penetrates through the rotating base 1 and is hinged to the rotating rod 53.

[0043] When the rotating hammer 54 rotates, an outward centrifugal force is generated, causing the rotating hammer 54 to swing outward under the action of this centrifugal force. The swinging of the rotating hammer 54 drives the sliding rod 431 to slide away from the lifting groove 41 in the sliding groove 45. The connecting rod 44 will change its angle with the movement of the slider 432. Since the top end of the connecting rod 44 is hinged to the bottom of the lifting disc 42 and the bottom end is hinged to the ejector member 43, the sliding of the sliding rod 431 will cause the connecting rod 44 to change its angle, thereby driving the lifting disc 42 to descend in the lifting groove 41, and finally driving the forming disc 22 loaded with green bricks to descend, covering the bottom of the forming ring 21, preparing for the subsequent rolling forming.

[0044] After the rolling forming is completed, the rotating seat gradually stops rotating, the centrifugal force of the rotating hammer 54 gradually disappears, and the rotating hammer 54 resets, driving the sliding rod 431 to slide in the sliding groove 45 towards the direction close to the lifting groove 41. Through the transmission of the connecting rod 44, the lifting disc 42 is lifted, so as to eject the formed green bricks from the forming die 2.

[0045] The structure of the ejector member 43 enables the centrifugal force of the rotating hammer 54 to not only be used to drive the locking assembly 5 to lock the forming die 2, but also to drive the ejector assembly 4 to adjust the position of the forming disc 22 at the same time, thereby optimizing the power transmission and cooperative working performance of the device, and improving the overall operation efficiency and stability of the device.
