Description

Technical Field

[0001] The present invention relates to the technical field of ceramic slab processing, and more particularly to a hot bending processing device for ceramic slabs. Background Art

[0002] As a high-performance building material, ceramic slabs have been widely used in the fields of architectural decoration and furniture manufacturing due to their excellent properties such as high strength, high hardness, wear resistance, and high temperature resistance. However, traditional ceramic slab processing methods often struggle to meet the requirements for complex shapes and curvatures, which limits the application scope of ceramic slabs in certain fields;

[0003] For example, during the processing, a template that perfectly fits the formed ceramic slab is required. However, since the slab is a plate-shaped structural material with inconsistent density during the forming process, when it is hot bent, the structure becomes unstable due to the two factors of extrusion and heating during the hot bending process. During the hot bending process, the side of the slab closer to the heat source receives more heat and has a higher temperature, while the other side receives less heat and has a relatively lower temperature. At this time, when extrusion shaping is performed, the slab is prone to breakage due to the temperature difference of the slab.

[0004] Therefore, we have made improvements in this regard and proposed a hot bending processing device for ceramic slabs. Summary of the Invention

[0005] The purpose of the present invention is to address the current situation where during hot bending, the side of the slab closer to the heat source receives more heat and has a higher temperature, while the other side receives less heat and has a relatively lower temperature.

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0038] As described in the background art, during the hot bending process, the side of the sheet material closer to the heat source receives more heat and has a higher temperature. Conversely, the other side receives less heat and has a relatively lower temperature. At this time, when extrusion shaping is performed, the sheet material is likely to break due to the temperature difference of the sheet material.

[0039] To solve this technical problem, the present invention provides a hot bending processing device for ceramic rock slabs, which is applied to enable the sheet material to be stably formed and avoid defective materials.

[0040] Specifically, please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 8 , a hot bending processing device for ceramic rock slabs specifically includes:

[0041] It includes a frame 1 and a lifter 2 arranged above the frame 1 and moving in the vertical direction. A cover plate 4 is arranged on the lifter 2. A loading device 5 is arranged inside the frame 1. A conveying device 6 is arranged on the frame 1. The loading device 5 includes a sliding seat 507 arranged inside the frame 1. A moving column 508 for carrying the rock slab is arranged on one side of the sliding seat 507. Two through grooves 509 are formed on the moving column 508. The sliding seat 507 is rotationally connected to the telescopic rod 506 through a ratchet and a pawl. A clamping plate 510 is fixedly connected to the sliding seat 507. A toothed groove plate 511 is fixedly connected to the sliding seat 507. A sliding groove 512 is formed on the sliding seat 507. The clamping plate 510 does not coincide with the sliding groove 512. The conveying device 6 includes a plurality of heating plates 603 installed at the bottom of the cover plate 4 for heating the rock slab.

[0042] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0044] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0045] Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10, A ceramic rock plate hot bending processing device. The carrying device 5 further includes a plurality of drive motors 501 fixedly connected to the inner wall of the bottom of the frame 1. On the outer wall of the top of a single drive motor 501, an installation frame 502 is fixedly connected, and the output end of the drive motor 501 is fixedly connected with a threaded rod 504.

[0046] By using multiple threaded rods 504, the positions between each threaded block 505 can be adjusted to different positions, so that they can be arranged in a semi-circular or wavy arc structure on the circular side of the moving column 508, enabling the plate to be extruded into a semi-cylindrical structure and combined into a complete cylindrical structure by splicing, making the selection more diverse during the hot bending process of the device and enabling the processed products to be more diverse.

[0047] The carrying device 5 further includes a threaded block 505 slidably connected to the installation frame 502. The threaded block 505 is threadedly connected to the threaded rod 504, and a telescopic rod 506 is fixedly connected to one side of the threaded block 505.

[0048] By adjusting the positions of the two sliding seats 507 at both ends on the frame 1 through the telescopic rod 506, the hot-bent part of the plate is changed under the action of the threaded column 609 and the extrusion die 610 at its top, causing local hot bending of the plate.

[0049] Please refer to Figure 8 and Figure 9 , A ceramic rock plate hot bending processing device. The number of sliding seats 507 between the two telescopic rods 506 is two, and the number of moving columns 508 between the two sliding seats 507 is one.

[0050] The carrying device 5 further includes a return spring 513 fixedly connected to the bottom end of the sliding groove 512. The top of the return spring 513 is fixedly connected with a sliding block 514. The sliding block 514 is slidably connected in the sliding groove 512, and a cross sleeve 515 is fixedly connected to the moving column 508.

[0051] After the moving column 508 is extruded by the extrusion die 610 at the top, it will also move in the sliding seat 507, resulting in a change in the support points of the moving column 508 on the plate.

[0052] The carrying device 5 further includes a perfusion fan 516 rotatably connected to the cross sleeve 515. A transmission gear 517 is fixedly connected to the perfusion fan 516. The transmission gear 517 is connected to the sliding block 514 through a bearing, and the tooth part of the transmission gear 517 meshes with the tooth part of the tooth groove plate 511.

[0053] Example 2 further optimizes the ceramic rock plate hot bending processing device provided in Example 1. Specifically, as Figure 3 、Figure 4 and Figure 5 As shown in Figure 5 , the conveying device 6 further includes a sealing groove 601 formed in the frame 1. A support column 602 is fixedly connected to the inner wall of the frame 1. A movement groove 604 is formed in the sealing groove 601. An anchoring block 605 that cooperates with the elevator 2 to lift itself is fixedly connected to the cover plate 4.

[0054] The cover plate 4 is lifted and lowered from the frame 1 by the elevator 2, so that the internal structure of the frame 1 is separated from the internal and external spaces, and the dissipation trend of the temperature in the frame 1 is reduced.

[0055] The conveying device 6 further includes two sealing plates 606 symmetrically arranged and fixedly connected to the outer wall of the cover plate 4. An adaptation groove 607 that engages with the mounting frame 502 is formed in a single sealing plate 606. A transverse groove 608 is formed in the cover plate 4. A threaded column 609 is rotatably connected in the transverse groove 608. The threaded column 609 is rotated by a motor on the cover plate 4, not marked in the figure, and is shown in Figure 5 which is shown in

[0056] Furthermore, as Figure 5 shown, the conveying device 6 further includes an extrusion die 610 threadedly connected to the threaded column 609 through a threaded sleeve. A plurality of pressure relief holes 611 are formed in the cover plate 4. A moving table 6041 is hinged in the movement groove 604 through a block. A unloading rack 612 is hinged to the moving table 6041 through two hinge plates.

[0057] The moving table 6041 can exist inside or outside the frame 1 in two states where the cover plate 4 covers the frame 1 or not.

[0058] The conveying device 6 further includes placing grooves 613 formed on both sides of the unloading rack 612. Four anti - detachment plates 614 for preventing the ceramic slab from falling off are slidably connected to the unloading rack 612. Two threaded buttons 615 are threadedly connected to a single anti - detachment plate 614. A plurality of support sleeves 616 that cooperate with the support columns 602 are fixedly connected to the side of the unloading rack 612 away from the moving table 6041.

[0059] The use process of a ceramic slab hot - bending processing device provided by the present invention is as follows:

[0060] 1. In the initial state when the device is in use, the cover plate 4 is lifted by the elevator 2 through a chain. The cover plate 4 moves on the frame 1 through a plurality of rollers. In Figure 4As shown in the figure, the internal space of the rack 1 can be exposed, and the sheet material is transported through the placement groove 613 between the anti - detachment plates 614 on the unloading rack 612. Rotate the threaded knob 615 so that the two anti - detachment plates 614 approach each other and completely clamp the sheet material (the threaded knob 615 is threadedly connected to the anti - detachment plate 614). After the clamping action is completed, the unloading rack 612 is flipped manually so that the support sleeve 616 contacts the support column 602 and at the same time the sheet material reaches the inside of the rack 1 (the support sleeve 616 is snap - connected to the support column 602). At the same time, it is necessary to push the moving table 6041 inward so that the moving table 6041 and the adaptation groove 607 on the sealing plate 606 are in the same plane. After the cover plate 4 drops and contacts the rack 1, the moving table 6041 is fitted into the adaptation groove 607 (the shape of the adaptation groove 607 is adapted to the shape of the moving table 6041).

[0061] 2. The preparatory work has been completed, and the sheet material already exists inside the rack 1. At this time, the cover plate 4 is pressed down to start the heating plate 603 (ventilation holes are provided at the bottom of the inner cavity of the rack 1 and the top of the cover plate 4, and the ventilation holes are prior art) to heat the sheet material. At this time, the position of the extrusion die 610 is adjusted by the movement of the threaded column 609.

[0062] After the sheet material is heated to soften, control the movement of the extrusion die 610. The extrusion die 610 extrudes the sheet material to shape the softened sheet material. Control the driving motor 501 to drive the threaded rod 504 to rotate, thereby controlling the upward movement of the threaded block 505 and the moving column 508. When the moving column 508 contacts the sheet material, continue to control the moving column 508 to rise. At this time, due to the blockage of the moving column 508 by the sheet material, relative movement occurs between the moving column 508 and the telescopic rod 506 in the vertical direction. The transmission gear 517 on the moving column 508 drops accordingly. Under the cooperation of the tooth groove plate 511, the transmission gear 517 and the perfusion fan 516 rotate. The air inside the rack 1, under the action of the perfusion fan 516, rushes into the moving column 508 through the end of the moving column 508 and is finally discharged upward through the through - slot 509, and then transmitted to the bottom of the sheet material, reducing the temperature difference between the top and bottom of the sheet material and avoiding the fracture of the sheet material during the hot - bending shaping process. After the hot - bending process tends to be stable, slightly adjust the positions of the threaded block 505, the moving column 508, and the telescopic rod 506 downward through the threaded rod 504 so that the sheet material gradually separates from the extrusion die 610. At the same time, the transmission gear 517 rotates under the cooperation of the tooth groove plate 511 due to the change in the position of the moving column 508. Due to the air duct effect, wind is provided for the stretching part and the temperature of the part of the sheet material extruded by the extrusion die 610 is lower than the temperature of the surrounding area, making the structure of this part more stable.

[0063] 3. When the hot bending gradually stabilizes, the sheet gradually shows an arc. After waiting for the processing duration to end and the sheet has been processed, the internal and external pressures are stabilized through the pressure relief hole 611, and the temperature is gradually decreased to an appropriate temperature. Then, the cover plate 4 is opened. At this time, due to the disappearance of the extrusion force, the reset spring 513 will gradually lift the sheet. When the temperature of the sheet reaches the normal temperature level, the sheet is separated from the bearing structure at its bottom, achieving the effect of stable demolding. At this time, the moving table 6041 is pulled and the unloading rack 612 is flipped to take out the material.
