Description

Technical Field

[0001] This utility model relates to the field of clay blank rolling technology, and in particular to an automatic rolling forming device for daily-use ceramic blanks. Background Technology

[0002] An automatic ceramic blank rolling forming device is a device used to automatically roll ceramic clay into blanks of a specific shape.

[0003] In the production and processing of daily-use ceramics, the clay blanks are usually placed in the lower mold slot of the automatic ceramic blank rolling forming equipment. Then, the lower mold is placed inside the drive rotary table on the equipment platform, and the upper rolling mold is extended into the lower mold slot. Then, the equipment is started, driving the lower mold and the upper rolling mold to rotate in opposite directions. Relying on the shape of the upper rolling mold itself and the contact, squeezing, and friction between it and the clay blank, the clay blank is gradually rolled into the shape designed in the inner cavity of the lower mold.

[0004] However, in the existing technology, the lower mold in most automatic rolling forming equipment for daily ceramic blanks is placed directly inside the drive rotary table. When the upper rolling mold extends into the lower mold to squeeze the clay blank, it will generate a certain friction. Since the lower mold itself is cylindrical and has a smooth outer wall, and there are no limiting measures set inside the drive rotary table or the lower mold itself, the lower mold will slide inside the drive rotary table, affecting the rolling forming effect.

[0026] Please see Figure 1-8 This utility model provides a technical solution: an automatic rolling forming device for daily-use ceramic blanks, comprising: a worktable 1, a U-shaped support frame 2 fixedly installed at the middle position of both ends of the top of the worktable 1, a lifting structure 3 provided on the upper surface of the U-shaped support frame 2, a rolling mold structure 4 provided below the lifting structure 3, a driving rotary table structure 5 provided at the center of the surface of the worktable 1, a lower mold 6 movably embedded in the top of the driving rotary table structure 5, mounting grooves 601 being provided on both sides of the outer wall of the lower mold 6 near the bottom, and limiting sliders 602 being fixedly connected to the bottom of both sides of the outer wall of the lower mold 6, with the two limiting sliders 602 correspondingly located directly below the two mounting grooves 601, and a docking limiting structure 7 being provided inside the two mounting grooves 601.

[0027] Specifically: the hemispherical arc-shaped slide grooves 5011 and long slide grooves 5012 provided on both sides of the inner cavity of the rotary table 501 cooperate with the docking limiting structures 7 and limiting sliders 602 provided on both sides of the outer wall of the lower mold 6. The two long slide grooves 5012 limit and guide the two limiting sliders 602, so that the two limiting balls 703 are aligned with the two hemispherical arc-shaped slide grooves 5011. The two limiting balls 703 inside the two docking limiting structures 7 extend into the hemispherical arc-shaped slide grooves 5011 to limit the lower mold 6, thus preventing the lower mold 6 from sliding relative to each other inside the rotary table 501.

[0028] In one embodiment, the four ends of the bottom of the workbench 1 are fixedly connected with support legs 101, and the top of the workbench 1 is fixedly installed with a controller 8 on one side.

[0029] Specifically, such as Figure 1 As shown: support leg 101 is used for support, and controller 8 is used to control the operation of internal components of the device.

[0030] In one embodiment, the lifting structure 3 includes an electric cylinder 301 fixedly installed at the top center of the U-shaped support frame 2.

T-shaped slide rods 303 are fixedly connected to the bottom of both sides of the installation frame 302. One end of the two T-shaped slide rods 303 is correspondingly and movably fitted into the interior of the two T-shaped slide grooves 201.

[0031] Specifically, such as Figure 1-2 As shown: The T-shaped slide 201 provides vertical movement space for the T-shaped slide rod 303 and guides it, thereby guiding the mounting frame 302 and preventing the mounting frame 302 from shifting during vertical movement.

[0032] In one embodiment, the rolling die structure 4 includes a first motor 401 fixedly installed at the bottom of the inner cavity of the electric cylinder 301. The output end of the first motor 401 moves through the bottom of the electric cylinder 301 and is fixedly installed with a mud-cutting disc 402. An upper rolling die 403 is fixedly installed at the center of the bottom of the mud-cutting disc 402.

[0033] Specifically, such as Figure 2-3 As shown: The first motor 401 drives the upper rolling mold 403 to rotate and roll the clay blank.

[0034] In one embodiment, the drive rotary table structure 5 includes a rotary table 501 and a mounting base 502. The mounting base 502 is fixedly installed at the center of the bottom of the worktable 1. A second motor 504 is fixedly installed at the bottom of the inner cavity of the mounting base 502. The output end of the second motor 504 is fixedly connected to a connecting shaft 503. The surface of the connecting shaft 503 is embedded through a bearing and installed inside the worktable 1. The top of the connecting shaft 503 is fixedly installed at the bottom of the rotary table 501. The rotary table 501 is located above the worktable 1. The lower end of the surface of the lower mold 6 is movably fitted and embedded inside the rotary table 501.

[0035] Specifically, such as Figure 2-3 As shown: When the second motor 504 runs, it drives the connecting shaft 503 to rotate, and at the same time drives the rotary table 501 to rotate. The rotary table 501 provides a space for the lower mold 6.

[0036] In one embodiment, the docking limiting structure 7 includes a sleeve 701 fixedly installed on one side of the inner cavity of the mounting groove 601. A T-shaped cavity is provided through the inside of the sleeve 701. A T-shaped connecting rod 702 is movably fitted inside the T-shaped cavity. One end of the T-shaped connecting rod 702 passes through the inside of the sleeve 701 and is fixedly connected to a limiting ball 703. A spring 704 is movably fitted on the outer wall surface of the sleeve 701. One end of the spring 704 is fixedly connected to one side of the inner cavity of the mounting groove 601, and the other end of the spring 704 is fixedly connected to one side of the limiting ball 703. One side of the limiting ball 703 is movably fitted inside the mounting groove 601.

[0037] Specifically, such as Figure 5-6 As shown in Figure 8: Mounting slot 601 provides installation space for docking limiting structure 7.

[0038] In one embodiment, hemispherical arc-shaped grooves 5011 are provided on both sides of the inner cavity of the rotary table 501 near the bottom, and long grooves 5012 are provided on both sides of the inner cavity of the rotary table 501 from top to bottom. The two long grooves 5012 penetrate the interior of the two hemispherical arc-shaped grooves 5011. The surfaces of the two limiting sliders 602 are correspondingly and movably fitted into the interior of the two long grooves 5012, and the other side of the two limiting balls 703 are correspondingly and movably fitted into the interior of the two hemispherical arc-shaped grooves 5011.

[0039] Specifically, such as Figure 3 , 4 As shown in Figures 6 and 7: The long slide groove 5012 provides space for the vertical movement of the limiting slider 602 and guides and limits it; the hemispherical arc-shaped slide groove 5011 provides a placement space for the limiting ball 703 and limits it. Since the outer wall of the limiting ball 703 is arc-shaped and the inner wall of the hemispherical arc-shaped slide groove 5011 is also arc-shaped, when the lower mold 6 is pulled upward, the upward-moving limiting ball 703 will shrink into the mounting groove 601 due to the pressure against the upper wall of the inner cavity of the hemispherical arc-shaped slide groove 5011.

[0040] Working principle:

[0041] In the automatic rolling forming device for daily-use ceramic blanks, the prepared clay blank is placed inside the lower mold 6. Then, the top of the lower mold 6 is held and moved above the rotary table 501. The two limiting sliders 602 on both sides of the outer wall of the lower mold 6 are aligned and placed into the two long sliding grooves 5012. The lower mold 6 is then moved downwards. During the downward movement of the lower mold 6, the exposed side of the two limiting balls 703 at the bottom of its two sides will touch the inner wall of the rotary table 501. At this time, the limiting balls 703... The T-shaped connecting rod 702 will move inward and contract inside the sleeve 701, compressing the spring 704. When the limiting ball 703 moves to the hemispherical arc-shaped slide groove 5011 on both sides below the inner cavity of the two rotating tables 501, it will lose compression. At this time, the spring 704 will reset, causing the T-shaped connecting rod 702 and the limiting ball 703 to move outward and reset, and causing the other side of the limiting ball 703 to fit into the hemispherical arc-shaped slide groove 5011. The bottom of the two lower molds 6 will also move to the bottom of the inner cavity of the rotating table 501.

[0042] With the above structural arrangement, the two long slide grooves 5012 limit and guide the two limiting sliders 602, so that the two limiting balls 703 can be aligned with the two hemispherical arc-shaped slide grooves 5011. The two limiting balls 703 inside the two docking limiting structures 7 extend into the hemispherical arc-shaped slide grooves 5011 to limit the lower mold 6, so as to avoid the phenomenon of relative sliding of the lower mold 6 inside the rotary table 501.

[0043] Once the lower mold 6 is in place, it can be operated by the controller 8. Under the control of the preset program of the controller 8, the electric cylinder 301 will drive the mounting frame 302 to move down, so that the upper rolling mold 403 extends into the interior of the lower mold 6. The first motor 401 will drive the upper rolling mold 403 to rotate through the mud cutting disc 402, and the second motor 504 will drive the rotary table 501 to rotate through the connecting shaft 503, and cause the lower mold 6 to rotate synchronously. By setting the rotation directions of the first motor 401 and the second motor 504 to be opposite, the reverse rotation can be achieved to roll and form the clay blank.

[0044] The control method of this utility model is to control the operation through a controller. The control circuit of the controller and the power supply are common knowledge in the field. Furthermore, this utility model does not involve any improvement to the connection of the controller and the power supply circuit. Therefore, this utility model will not explain the control technology and circuit connection in detail.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
