[0057] The present invention discloses a ceramic roller press, comprising a frame, a first roller group 2, a second roller group 3, a first steel belt 4 sleeved on the first roller group 2, and a second steel belt 5 sleeved on the second roller group 3. The first roller group 2 and the second roller group 3 are positioned inside the frame. In order to facilitate the removal or replacement of the first steel belt 4 from the frame, the invention in this embodiment mainly lies in the improvement of the structure of the frame. The frame is described in detail below.

[0058] For details, please refer to Figures 1 to 3 The frame includes a main frame 1, a rotating frame 8, a fixed side plate 13 and a rotating side plate 10. The first roller group 2 and the second roller group 3 are both arranged on the main frame 1 and can rotate relative to the main frame 1 respectively, and drive the first steel belt 4 and the second steel belt 5 to rotate. The first roller group 2 includes a first active roller 21, a first pressure roller 22 and a first driven roller 23; the second roller group 3 includes a second active roller 31, a second pressure roller 32 and a second driven roller 33, wherein the first active roller 21 and the first driven roller 23 are transmission-connected to the first steel belt 4. The second active roller 31 and the second driven roller 33 are connected to the second steel belt 5 in a transmission manner. At least part of the surface of the first pressing roller 22 abuts against the first steel belt 4, and the second pressing roller 32 abuts against the second steel belt 5 at least partly. There is a gap between the first pressing roller 22 and the second pressing roller 32. When the material is placed between the first steel belt 4 and the second steel belt 5, and the material is transmitted along the first steel belt 4 and / or the second steel belt 5 to the gap formed by the first pressing roller 22 and the second pressing roller 32, the first pressing roller 22 and the second pressing roller 32 extrude and form the material. The fixed side plate 13 is used to position the first roller group 2 to prevent the first steel belt 4 from falling off the first roller group 2. The rotating side plate 10 is hingedly connected to the main frame 1 and can abut against the fixed side plate 13 to support or release the first roller group 2 and can withstand the pressure when the first roller group 2 is pressurized. The rotating side plate 10 is hingedly connected to the main frame 1 through a rotating shaft 15; one end of the rotating frame 8 is hingedly connected to the main frame 1, and the other end is engaged with the rotating side plate 10 to enclose to form the operating space of the first roller group 2.

[0059] It can be understood that the opening and closing directions of the rotating frame 8 and the rotating side plate 10 are different. In this embodiment, the opening and closing method of the rotating frame 8 is top-opening, and the rotating side plate 10 is side-opening, which can effectively reduce the space occupied by the opening and closing of the frame, and at the same time obtain a wider space for disassembly or replacement of the steel belt. Of course, the opening and closing directions of the two can also be changed, and such conversion methods all fall within the protection scope of the present invention.

[0060] Furthermore, the frame also includes a rotary drive cylinder 11, and an ear seat 101 is provided on the rotary side plate 10. One end of the rotary drive cylinder 11 is hingedly connected to the main frame 1, and the other end is hingedly connected to the ear seat 101 of the rotary side plate 10. The rotary drive cylinder 11 rotates relative to the main frame 1 to drive the rotary side plate 10 to rotate relative to the fixed side plate 13 to remove or replace the first steel belt 4 on the first roller group 2. For details, please refer to Figure 5 , a locking device 16 is provided on the rotating frame 8, which is used to engage and connect the rotating side plate 10 and the rotating frame 8. When the rotating side plate 10 is engaged with the rotating frame 8, it is used to enclose and form the running space of the first roller group 2; when the rotating frame 8 is disconnected from the rotating side plate 10 and the rotating side plate 10 rotates relative to the fixed side plate 13, a space for disassembling or replacing the first steel belt 4 wound on the first roller group 2 is formed; when the steel belt is disassembled or replaced, the locking device 16 is first released to engage the rotating side plate 10. The side plate 10 and the rotating frame 8 are snap-connected, the rotating frame 8 is rotated, and then the rotating side plate 10 is rotated until the plane of the rotating side plate 10 is perpendicular to the plane of the fixed side plate 13, and the first pressure roller 22 is lifted so that it does not abut against the first steel belt 4, and then the first steel belt 4 is removed or replaced from the first roller group 2. The first steel belt 4 can be removed and replaced without disassembling each roller in the first roller group 2, which significantly simplifies the process of steel belt replacement, saves manpower and material resources, and improves the efficiency of steel belt replacement.

[0061] It can be understood that a pad 14 is provided under the main frame 1 connected to one end of the rotating side plate 10. When the second steel belt 5 is disassembled or replaced, the pad 14 can be removed and the above-mentioned process of disassembling the first steel belt 4 is repeated. First, the locking device 16 is released from the locking connection between the rotating side plate 10 and the rotating frame 8, the rotating frame 8 is rotated, and then the rotating side plate 10 is rotated until the plane where the rotating side plate 10 is located is perpendicular to the plane where the fixed side plate 13 is located, so as to form a space for disassembling or replacing the second steel belt 5. With the cooperation of other auxiliary equipment, the second steel belt 5 is disassembled or replaced. Among them, other auxiliary equipment is not an improvement point of the present invention and will not be further elaborated here. The spacing between the second steel belt 5 and the first steel belt 4 is adjustable, and the thickness of the ceramic roller forming can be adjusted by adjusting the spacing between the second steel belt 5 and the first steel belt 4.

[0062] Specifically, a pair of upper support blocks are provided on the fixed side plate 13, namely the first upper support block 61 and the second upper support block 62, and a pair of lower support blocks are provided on the rotating side plate 10, namely the first lower support block 63 and the second lower support block 64. When the rotating side plate 10 abuts against the fixed side plate 13 to support the first roller group 2, the first upper support block 61 abuts against the first lower support block 63, and the second upper support block 62 abuts against the second lower support block 64. The paired upper and lower support blocks are used to support the fixed side plate 13 and increase the rigidity of the frame; a first detection device 7 is also provided on the fixed side plate 13, and the first detection device 7 is provided on the surface of the side where the fixed side plate 13 abuts against the rotating side plate 10, for detecting whether the rotating side plate 10 abuts against the fixed side plate 13; the frame also includes a limit plate 12, which is provided on the same side of the first detection device 7 on the fixed side plate 13, for rotational positioning of the rotating side plate 10.

[0063] Furthermore, the frame also includes a rotating mechanism 9, one end of the rotating mechanism 9 is hingedly connected to the main frame 1, and the other end is hingedly connected to the rotating frame 8. Please refer to Figure 4 and Figure 6 The rotating mechanism 9 includes a bracket 91 and a mounting seat 93. One end of the bracket 91 is fixedly connected to the main frame 1, and the other end is hingedly connected to the rotating frame 8. The mounting seat 93 is fixedly connected to the main frame 1. A first driving cylinder 94 is provided on the mounting seat 93. One end of the first driving cylinder 94 is hingedly connected to the mounting seat 93, and the other end is hingedly connected to the rotating frame 8. The rotating mechanism 9 also includes a second detection device 92. The second detection device 92 is fixedly provided on the bracket 91, and is used to detect whether the opening and closing angle of the rotating frame 8 reaches a preset angle.

[0064] Furthermore, the rotating mechanism 9 also includes a limit sleeve 95, which is slidably provided on the first driving cylinder 94 and can be positioned on the first driving cylinder 94 for positioning the limit position of the rotation of the rotating frame 8. When the first driving cylinder 94 drives the rotating frame 8 to rotate in the direction away from the rotating side plate 10 until the rotating frame 8 abuts against the limit sleeve 95, this position is the limit position of the rotation of the rotating frame 8. It can be understood that the limit position is not fixed. The operator can adjust the position of the limit sleeve 95 according to the actual required opening angle of the rotating frame 8. The limit sleeve 95 works together with the second detection device 92 to determine whether the rotation angle of the rotating frame 8 reaches the preset angle; the rotating mechanism 9 also includes a second driving cylinder 96 and a safety hook 97, one end of the safety hook 97 is hinged to the second driving cylinder 96, and the other end is hinged to the mounting seat 93; when the second driving cylinder 96 is in the extended state, the safety hook 97 is engaged with the rotating frame 8 for locking the rotating frame 8. Before closing the rotating frame 8, the safety hook 97 must be disconnected from the rotating frame 8.

[0065] To sum up, when the ceramic roller press in this embodiment performs the process of disassembling the first steel belt 4, first, the locking device 16 disconnects the locking connection between the rotating frame 8 and the rotating side plate 10, and the first drive cylinder 94 drives the rotating frame 8 to rotate in the direction away from the rotating side plate 10. The second detection device 92 determines whether the rotation angle of the rotating frame 8 reaches the preset angle. When the preset angle is reached or the rotating frame 8 abuts the limit sleeve 95, the first drive cylinder 94 stops working, exposing the first roller group 2. Then the user rotates the rotating side plate 10 until the plane where the rotating side plate 10 is located is perpendicular to the plane where the fixed side plate 13 is located, and lifts the first pressing roller 22 so that it does not abut against the first steel belt 4. Then, the first steel belt 4 is removed or replaced from the first roller group 2. The first steel belt 4 can be removed and replaced without disassembling the first roller group 2, which significantly simplifies the process of steel belt replacement, saves manpower and material resources, and improves the efficiency of steel belt replacement.
