Description

Technical Field

[0001] This utility model relates to the field of ceramic production equipment technology, and in particular to a device for realizing the vertical erection of ceramic roller blanks. Background Technology

[0002] Vertical drying of ceramic blanks is a drying process specifically designed for blanks of certain shapes (such as tubular or long strip blanks with a large length-to-diameter ratio). By placing the blanks vertically, this process not only improves drying efficiency but also reduces the risk of deformation. Specifically, vertical drying involves placing the ceramic blanks vertically on supports or conveyor devices, using hot air circulation or radiant heating to allow moisture to evaporate evenly and slowly from the inside of the blank. Perforated supports or clamps are used to fix the blanks, ensuring their vertical stability and preventing tipping. The core advantages of vertical drying are: the blanks only contact the supports through their bottom or a few contact points, thus reducing the risk of localized stress and deformation caused by the support surface; the vertical direction facilitates even radial distribution of moisture, reducing the possibility of radial deformation and cracking, while also avoiding collapse and bending caused by their own weight when laid flat; hot air flows along the axial direction of the blanks, reducing the temperature difference in the radial cross-section and preventing cracking caused by uneven evaporation at different points in the radial cross-section; the vertical arrangement allows the blanks to occupy more space upwards, enabling denser placement in the drying chamber, which is especially suitable for long ceramic roller products.

[0003] In summary, combining vacuum extrusion molding of ceramic rollers with vertical drying offers significant technical advantages. However, in traditional processes, vacuum extrusion molding of ceramic roller preforms typically employs horizontal extrusion equipment. Therefore, implementing this technology requires horizontally transporting the ceramic roller preform from the extrusion molding area to a vertical drying chamber and performing the vertical operation within the chamber. This process easily leads to deformation or breakage of the preform, thus limiting the practical application of this technology to some extent.

[0004] Therefore, it is necessary to develop a device for achieving the vertical erection of ceramic roller blanks. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a device for erecting ceramic roller blanks, thereby realizing the automated erection of ceramic roller blanks, reducing the labor intensity of workers, and reducing the risk of deformation and breakage of ceramic roller blanks during operation.

[0006] To solve the above-mentioned technical problems, this utility model provides a device for erecting a ceramic roller blank, comprising a first rotary drive mechanism, a second rotary drive mechanism, and a fixing groove plate arranged sequentially. The ceramic roller blank is supported by a core tube. The first rotary drive mechanism drives the ceramic roller blank to rotate until the front end of the core tube abuts against the fixing groove plate. The second rotary drive mechanism drives the ceramic roller blank to rotate further until it is erected.

[0007] As an improvement to the above solution, the first rotary drive mechanism is provided with a first guide wheel, and the second rotary drive mechanism is provided with a second guide wheel. Both the first and second guide wheels have grooved surfaces for rolling contact with the ceramic roller blank. The initial position of the second guide wheel is below the first guide wheel.

[0008] As an improvement to the above solution, the top of the first rotary drive mechanism is provided with a conveyor belt and a lifting drive mechanism. The conveyor belt is used to transport the ceramic roller blank towards the fixed groove plate. The lifting drive mechanism is connected to the first guide wheel and is used to drive the first guide wheel to lift, thereby pushing the ceramic roller blank away from the conveyor belt.

[0009] As an improvement to the above solution, the conveyor belt includes a belt, a driving pulley and a driven pulley that cooperate with the belt for transmission, and a plurality of transition pulleys evenly distributed between the driving pulley and the driven pulley. The driving pulley, the driven pulley, and the transition pulleys are all provided with positioning grooves circumferentially around the wheel body in the middle section of the wheel body. Each positioning groove includes a horizontally arranged cylindrical surface and frustum surfaces symmetrically arranged on both sides of the cylindrical surface.

[0010] As an improvement to the above solution, a billet erecting frame is also included. The first rotary drive mechanism further includes a first telescopic drive mechanism and a transfer frame. The conveyor belt and the lifting drive mechanism are both connected to the transfer frame; one end of the transfer frame near the second rotary drive mechanism is hinged to the billet erecting frame; the first telescopic drive mechanism is connected to the billet erecting frame; the telescopic end of the first telescopic drive mechanism is connected to the transfer frame, for driving the first telescopic drive mechanism transfer frame to rotate relative to the billet erecting frame.

[0011] As an improvement to the above solution, the lifting drive mechanism is configured to be at least two, and the two lifting drive mechanisms are separated by a conveyor belt.

[0012] As an improvement to the above solution, a billet erecting frame is also included. The second rotary drive mechanism includes a rotating arm, a second telescopic drive mechanism, a slide block, and a third telescopic drive mechanism. Specifically, the end of the rotating arm near the fixed slot plate is rotatably connected to the billet erecting frame; the fixed end of the second telescopic drive mechanism is connected to the billet erecting frame, and its telescopic end faces the first rotary drive mechanism and is connected to the slide block; the slide block and the billet erecting frame form a sliding fit; the fixed end of the third telescopic drive mechanism is connected to the slide block, and its telescopic end is hinged to the rotating arm.

[0013] As an improvement to the above solution, the fixed groove plate includes a base plate, a rounded corner plate, and a vertical plate arranged sequentially from bottom to top, wherein the rounded corner plate is an arc-shaped transition plate connecting the base plate and the vertical plate.

[0014] As an improvement to the above solution, both the rounded corner plate and the upright plate are provided with opposing folded edges on the left and right sides facing the second rotary drive mechanism.

[0015] As an improvement to the above solution, the bottom plate, the rounded corner plate, and the upright plate are provided with cushioning material on the side facing the core.

[0016] Implementing this utility model has the following beneficial effects:

[0017] This utility model discloses a device for erecting ceramic roller blanks. Through the cooperation of a first rotary drive mechanism, a second rotary drive mechanism, and a fixed groove plate, the ceramic roller blank, supported by a core tube, first rotates under the drive of the first rotary drive mechanism, causing its front end to abut against the fixed groove plate. Subsequently, under the drive of the second rotary drive mechanism, further processing is completed, ultimately achieving the automatic erection of the ceramic roller blank. This device effectively reduces the labor intensity of workers and also reduces the risk of deformation and breakage of the ceramic roller blank by automating the erection of the ceramic roller blank.

[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, this utility model discloses an embodiment of a device for erecting a ceramic roller blank, comprising a first rotary drive mechanism 1, a second rotary drive mechanism 2, and a fixing groove plate 3 arranged sequentially. The ceramic roller blank is formed on a core. The first rotary drive mechanism 1 drives the ceramic roller blank to rotate until the front end of the core abuts against the fixing groove plate 3. The second rotary drive mechanism 2 drives the ceramic roller blank to rotate further to an upright position.

[0026] In this embodiment, the first rotary drive mechanism 1 cooperates with the second rotary drive mechanism 2 and the fixed groove plate 3 to make the ceramic roller blank supported by the tube core rotate under the drive of the first rotary drive mechanism 1 until the end of the tube core abuts against the fixed groove plate 3. Then, under the drive of the second rotary drive mechanism 2, it continues to rotate until it is upright. This realizes the automated uprighting operation of the ceramic roller blank, reduces the labor intensity of workers, and reduces the risk of deformation and breakage of the ceramic roller blank.

[0027] During the production process, the green body erection device is located inside the drying chamber, where the ceramic roller green body erected by it is dried.

[0028] In this embodiment, the billet erecting device is provided with a billet erecting frame 4. The first rotary drive mechanism 1 and the second rotary drive mechanism 2 of the billet erecting device are both mounted on the billet erecting frame 4, and the hinge position between the first rotary drive mechanism 1 and the billet erecting frame 4 is located obliquely above the hinge position between the second rotary drive mechanism 2 and the billet erecting frame 4. The second rotary drive mechanism 2 can increase the tilt angle of the ceramic roller billet within a wider angle range.

[0029] The first rotary drive mechanism 1 is equipped with a first guide wheel 11, and the second rotary drive mechanism 2 is equipped with a second guide wheel 21. Both the first guide wheel 11 and the second guide wheel 21 have grooved surfaces for rolling contact with the ceramic roller blank. The initial position of the second guide wheel 21 is below the first guide wheel 11. The grooved surfaces of the first guide wheel 11 and the second guide wheel 21 ensure that the ceramic roller blank's deviation is limited during transport and erection. Furthermore, the contact points between the first guide wheel 11 and the second guide wheel 21 and the ceramic roller blank are wrapped with a soft material to prevent deformation of the ceramic roller blank. The soft material provides excellent cushioning during the erection of the ceramic roller blank, reducing damage while ensuring automated erection. The soft material includes, but is not limited to, foam materials (such as polyurethane foam, polystyrene foam, polyethylene foam, etc.), elastic polymers (such as silicone, latex, etc.), fibers and fabrics (such as felt, sponge, etc.), and natural materials (such as cork, natural rubber, etc.). When the first rotary drive mechanism 1 drives the ceramic roller blank to rotate, the first guide wheel 11 rolls in contact with the ceramic roller blank so that when the ceramic roller blank tilts as the first rotary drive mechanism 1 rotates, it moves toward the fixed groove plate 3 on the first guide wheel 11 until the end of the tube abuts against the fixed groove plate 3; when the second rotary drive mechanism 2 drives the ceramic roller blank to rotate, the second guide wheel 21 rolls in contact with the ceramic roller blank so that the tube core rotates with the abutment position of the front end against the fixed groove plate 3 as the fulcrum until the tube core is completely upright.

[0030] In this embodiment, a conveyor belt 12 and a lifting drive mechanism 13 are preferably provided on top of the first rotary drive mechanism 1. The conveyor belt 12 transports the ceramic roller blank; the lifting drive mechanism 13 is connected to the first guide wheel 11 and is used to drive the first guide wheel 11 to lift the ceramic roller blank away from the conveyor belt 12. During the inclined downward movement of the ceramic roller blank, the sliding friction between the ceramic roller blank and the conveyor belt 12 is changed to rolling friction with the first guide wheel 11, which greatly reduces the friction on the surface of the ceramic roller blank and protects the outer surface of the ceramic roller blank from damage.

[0031] The first rotary drive mechanism 1 in this embodiment also includes a first telescopic drive mechanism 15 and a transfer frame 16. Each conveyor belt 12 is connected through the transfer frame 16, and each lifting drive mechanism 13 is also fixed to the transfer frame 16. The end of the transfer frame 16 near the second rotary drive mechanism 2 is hinged to the billet erecting frame 4; the first telescopic drive mechanism 15 is connected to the billet erecting frame 4, and its telescopic end is connected to the transfer frame 16 to drive the transfer frame 16 to rotate relative to the billet erecting frame 4, that is, to adjust the tilt angle of the conveyor belt 12.

[0032] During the process of the first rotary drive mechanism 1 driving the ceramic roller blank to rotate until the end of the tube core abuts against the fixed groove plate 3, the following two rotation processes can be selected as needed:

[0033] Firstly, the first telescopic drive mechanism 15 of the first rotary drive mechanism 1 drives the transmission frame 16 to tilt relative to the upright frame 4 of the blank, changing the conveying of the ceramic roller blank on the conveyor belt 12 from horizontal to inclined. When the ceramic roller blank is conveyed to the third preset position (at which point the front end of the core is about to touch the fixed groove plate 3), the lifting drive mechanism 13 drives the first guide wheel 11 to lift the ceramic roller blank (a sensor can be set at the preset position, and the controller controls the action of the lifting drive mechanism 13 by feedback from the position sensor on whether the ceramic roller blank has been conveyed to the specified position, ensuring that the front end of the core is lifted away from the conveyor belt 12 by the first guide wheel 11 before it comes into contact with the fixed groove plate 3). The ceramic roller blank is supported by the first guide wheel 11 and moves towards the fixed groove plate 3 until the front end of the core comes into contact with the fixed groove plate 3. In this rotation process, when the first telescopic drive mechanism 15 drives the transmission frame 16 to start rotating, the ceramic roller blank is still being conveyed at an incline on the conveyor belt 12. When the front end of the tube core is about to reach the fixed groove plate 3, the ceramic roller blank is separated from the surface of the conveyor belt 12. This avoids the ceramic roller blank from being violently rubbed against the surface of the conveyor belt 12 during the high-speed movement stage of the downward slide (when it is about to reach the end point) due to the acceleration of gravity, thereby further avoiding the occurrence of surface damage to the ceramic roller blank.

[0034] Secondly, the lifting drive mechanism 13 lifts the ceramic roller blank before the first rotary drive mechanism 1 drives it to rotate. That is, when the conveyor belt 12 transports the ceramic roller blank to the first preset position, the ceramic roller blank is lifted by the first guide wheel 11 driven by the lifting drive mechanism 13 (a sensor can be set at the first preset position, and the controller controls the action of the lifting drive mechanism 13 by feeding back whether the ceramic roller blank has been transported to the specified position through the position sensor). At this time, the ceramic roller blank will move forward a certain distance under the action of inertia, reaching the second preset position. After that, the first telescopic drive mechanism 15 drives the transmission frame 16 to rotate relative to the blank vertical frame 4. Due to gravity, the ceramic roller blank moves towards the fixed groove plate 3 on the first guide wheel 11 until the core abuts against the fixed groove plate 3. During this process, when each conveyor belt 12 transports the ceramic roller blank to the first preset position, the lifting drive mechanism 13 drives the first guide wheel 11 to lift, thereby pushing the ceramic roller blank away from the conveyor belt 12. At this time, the first rotation drive mechanism 1 drives the ceramic roller blank to rotate for the first time, so that the front end of the core tube comes into contact with the fixed groove plate 3. In this rotation process, the movement trajectory of the ceramic roller blank is more stable and controllable, and the rotation speed can reach a higher level, avoiding the generation of sliding friction between the ceramic roller blank and the surface of the conveyor belt 12, and better protecting the surface of the ceramic roller blank.

[0035] Specifically, in this embodiment, at least two lifting drive mechanisms 13 are provided, and the two lifting drive mechanisms 13 are separated by a conveyor belt 12 so that the first guide wheel 11 on the lifting unit can stably support the ceramic roller blank on the conveyor belt 12. At least one conveyor belt 12 is provided, and in this embodiment, there are two. One conveyor belt 12 is located between the two lifting drive mechanisms 13, and the other conveyor belt 12 is located on the side of the first guide wheel 11 away from the second rotary drive mechanism 2.

[0036] In this embodiment, second limiting rollers 14 are provided on both sides of the conveyor belt 12 to ensure that the ceramic roller blank remains on the mirror plane of the vertical device and does not roll off during the transmission of the conveyor belt 12. The conveyor belt 12 in this embodiment includes a belt a, a driving pulley b, a driven pulley c, and a transition pulley d. The transition pulley d is evenly distributed between the driving pulley b and the driven pulley c. The driving pulley b, driven pulley c, and transition pulley d, which cooperate with the belt a, are all provided with positioning grooves circumferentially around the wheel body in the middle section of the wheel body. The positioning groove includes a horizontally arranged cylindrical surface and inclined or concave arc surfaces symmetrically arranged on both sides of the cylindrical surface; in this embodiment, a frustum surface is preferred. The positioning groove structure designed for the driving pulley b, driven pulley c, and transition pulley d allows belt a to be suspended above the cylindrical surface of the positioning groove when not transporting the ceramic roller blank. When belt a transports the ceramic roller blank, it wraps around the lower part of the blank, increasing the contact area between belt a and the blank. This also prevents the bottom of the blank from making hard contact with belt a during transport, ensuring stability and preventing deformation of the blank during transport. Unlike the driven pulley c, the driving pulley b also has circumferentially protruding teeth at both ends, extending axially to the inclined edge of the frustum surface to drive belt a.

[0037] The second rotary drive mechanism 2 in this embodiment specifically includes a rotating arm 22, a second telescopic drive mechanism 23, a slide block 24, and a third telescopic drive mechanism 25. One end of the rotating arm 22 near the fixed groove plate 3 is rotatably connected to the blank erecting frame 4, and the top of the other end is provided with a second guide wheel 21. The fixed end of the second telescopic drive mechanism 23 is connected to the blank erecting frame 4; the telescopic end of the second telescopic drive mechanism 23 faces the first rotary drive mechanism 1 and is hinged to the slide block 24; the slide block 24 is slidably engaged with the blank erecting frame 4, and the fixed end of the third telescopic drive mechanism 25 is connected to the slide block 24; the telescopic end of the third telescopic drive mechanism 25 is hinged to the rotating arm 22. To increase the support points for the ceramic roller blank, the second guide wheel 21 on the rotating arm 22 can be set to two or more. As the second telescopic drive mechanism 23 retracts to drive the slide block 24 to move, and the third telescopic drive mechanism 25 extends, the swing range of the rotating arm 22 gradually increases until the ceramic roller blank is erected.

[0038] The fixing groove plate 3 of the billet erecting device can be connected to the billet erecting frame 4 or set separately in the drying oven. The fixing groove plate 3 is roughly L-shaped and specifically includes a base plate 31, a rounded corner plate 32, and a vertical plate 33 arranged sequentially from bottom to top. The base plate 31 is horizontally set and close to the ground, while the vertical plate 33 can be perpendicular to the ground or its top can be set to lean towards the base plate 31. The rounded corner plate 32 is an arc-shaped transition plate connecting the base plate 31 and the vertical plate 33. After the tube core abuts against the fixing groove plate 3, the rounded corner plate 32 can provide relatively stable support for the front end of the tube core during the erection process, helping to maintain the stability of the front end fulcrum during the rotation of the tube core. In this embodiment, both the rounded corner plate 32 and the vertical plate 33 have folded edges on the left and right sides (the surfaces on both sides are not flat) that are bent towards the second rotation drive mechanism to help prevent the front end of the tube core from sliding out of the fixing groove plate 3. In this embodiment, a layer of buffer material is also provided on the side of the base plate 31, the rounded corner plate 32, the upright plate 33 opposite to the core tube, so as to buffer the end of the core tube.

[0039] In this embodiment, the blank erecting frame 4 is equipped with casters 41 and retractable adjustable support legs 42. The casters 41 not only provide stability but also facilitate the movement of the blank erecting frame 4 when the two support legs 42 are retracted. After the blank erecting frame 4 has moved to a preset position, the support legs 42 are lowered to fix the frame position. Once the ceramic roller blanks in one drying chamber are erected, the ceramic roller blank erecting device can be moved to the next drying chamber via the casters, offering good flexibility.

[0040] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
