Description

Technical Field

[0001] This utility model relates to the field of ceramic processing technology, and in particular to an improved ceramic roll forming equipment. Background Technology

[0002] Ceramic roll forming equipment is a ceramic processing device used to process ceramic blanks. Chinese utility model patent CN221697281U, authorized by the applicant, describes a ceramic roll forming device, including a roll forming head mechanism, an upper mold frame, a lower mold frame, an upper mold, a lower mold, pneumatic components, a pneumatic rotary joint, a rotating device, and a top mold device. During ceramic roll forming, the pneumatic pressure rod mechanism also rotates synchronously, ensuring that the upper and lower molds do not move vertically.

[0003] However, this ceramic roll forming equipment has the following drawbacks during use: 1. At least two pneumatic pressure rod mechanisms are fixedly connected to the side of the upper mold frame. During the roll forming process, the pneumatic pressure rod mechanisms rotate with the rotation of the upper mold frame. Since the pneumatic pressure rod mechanisms protrude from the outer circumferential wall of the upper mold frame, they are prone to hitting the operators working on the side during rotation, causing injury. 2. A pneumatic rotary joint is installed on the rotating shaft between the bottom of the lower mold frame and the top surface of the machine frame, which not only increases the equipment cost but also increases the installation height of the lower mold frame (i.e., the height from the top surface of the machine frame). Utility Model Content

[0004] This utility model provides an improved ceramic roll forming equipment, which aims to solve the problems of existing ceramic roll forming equipment that easily injure operators during operation.

Several lifting devices are fixedly installed on the step, and the upper shell is fixedly connected to the top of the lifting devices. When the top mold device pushes the upper mold and the lower mold to the highest position, the lifting device lifts the upper shell until it is aligned with the bottom surface of the lower mold.

[0010] In a preferred embodiment, the rotating device includes a rotating shaft and a power mechanism for driving the rotating shaft to rotate. The rotating shaft is fixedly connected to the bottom of the lower mold frame. A mounting housing is also fixedly provided on the side wall of the frame. The mounting housing covers the outside of the rotating shaft, and the rotating shaft is rotatably inserted through the mounting housing via a bearing.

[0011] In a preferred embodiment, two gas channels are provided on the side wall of the aforementioned rotating shaft, each gas channel having a first air pipe interface and a second air pipe interface; a first sealed chamber and a second sealed chamber are formed between the rotating shaft and the mounting housing, respectively corresponding to the first air pipe structure of the two gas channels; the first sealed chamber and the second sealed chamber each have an air hole on the corresponding side wall of the mounting housing, and the two air holes are respectively connected to the gas source system; each second air pipe port is connected to several air pipes, and each air pipe is connected to a solenoid valve, the solenoid valve being correspondingly connected to the lifting cylinder and the pressure rod cylinder.

[0012] In a preferred embodiment, a first sealing element is fixedly installed between the rotating shaft and the mounting housing at the upper and lower parts of one of the first tracheal ports, and the first sealing element, the rotating shaft, and the mounting housing form the first sealed chamber; a second sealing element is fixedly installed between the rotating shaft and the mounting housing at the upper and lower parts of the other first tracheal port, and the second sealing element, the rotating shaft, and the mounting housing form the second sealed chamber.

[0013] In a preferred embodiment, the top mold device includes a top plate, a top rod, a connecting rod, and a top mold cylinder. The rotating shaft has a central hole along its central axis.

[0016] As can be seen from the above description of the structure of this utility model, this utility model has the following advantages: 1. The ceramic roll forming equipment of this utility model is equipped with a mold shell that covers the pneumatic pressure rod mechanism and the mold frame inside. The top surface of the upper shell of the mold shell is not lower than the top surface of the pneumatic pressure rod mechanism when the roll forming is in operation, which can prevent the pneumatic pressure rod mechanism from hitting the operator when it rotates with the mold frame, thus ensuring the safety of the operator. The opening side wall of the mold shell is located outside the maximum projection range of the mold frame in the vertical direction, which ensures that the mold frame can be smoothly lifted by the top mold device.

[0017] 2. The ceramic roll forming equipment of this utility model has several lifting devices fixed on the steps for driving the upper shell to rise or fall.

[0018] 3. The ceramic roll forming equipment of this utility model has two gas channels on the rotating shaft. A first sealed chamber, connected to the first gas pipe interface of each of the two gas channels, and a second sealed chamber, connected to a vent, are respectively installed between the rotating shaft and the housing. Both the first and second sealed chambers have air holes on their side walls. When the rotating shaft rotates, the housing remains stationary, and the first gas pipe interfaces of the two gas channels are always connected to their corresponding sealed chambers. Using the above-described rotating shaft and housing structure to supply air to pneumatic components and cylinders eliminates the need for pneumatic rotary joints, saving equipment costs and reducing the installation height of the mold frame.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details. Well-known components, methods, and processes will not be described in detail below.

[0026] An improved ceramic roll forming equipment, referring to Figure 1 It includes a frame 1, a rolling head mechanism 20, a mold frame, a mold, a pneumatic pressure bar mechanism 50, a rotating device 60, and a top mold device 70.

[0027] Reference Figure 1 The mold frame shown in this embodiment includes an upper mold frame 31 and a lower mold frame 32, and the mold includes an upper mold 41 and a lower mold 42. The lower mold 42 is positioned and installed inside the lower mold frame 32. An installation groove is provided on the inner top side of the lower mold frame 32, and a rubber ring 321 is installed on the installation groove. A positioning groove 421 is provided on the side wall of the lower mold 42, and the lower mold 42 is engaged with the rubber ring 321 through the positioning groove 421. The upper mold 41 is installed on the top of the lower mold 42 through a positioning groove and a positioning protrusion. The rolling head mechanism 20 is located above the mold cavity formed by the upper mold 41 and the lower mold 42. During ceramic rolling molding, the rolling head mechanism 20 rolls the clay placed in the upper mold 41 and the lower mold 42. The rolling head mechanism is a common clay rolling mechanism in the art and is not the focus of the improvement of the solution, so it will not be described in detail here.

[0028] Reference Figure 1 and Figure 2The outer wall of the lower mold frame 32 is fixedly connected to the upper mold frame 31 by threads. The connection height of the upper mold frame 31 can be adjusted according to the size of different molds. A step 311 is fixedly provided on the outer wall of the upper mold frame 31. The step 311 can be a continuous annular step or multiple steps spaced apart. At least two pneumatic pressure rod mechanisms 50 are fixedly connected to the step 311. In this embodiment, there are two pneumatic pressure rod mechanisms 50, which are symmetrically arranged on the steps 311 on both sides of the upper mold frame 31. The pneumatic pressure rod mechanism 50 includes a pneumatic component, a pressure rod 52, and a support rod 53. The pneumatic component is specifically a pressure rod cylinder 51. A pressure rod 52 is hinged to the front end of the piston rod of the pressure rod cylinder 51. One end of the support rod 53 is hinged to the pressure rod cylinder 51, and the other end of the support rod 53 is hinged to the pressure rod 52.

[0029] Refer to 1 and Figure 4 The top edge of the upper mold 41 is provided with several notches 410. In this embodiment, two notches 410 are provided on the top edge of the upper mold 41, and the ends of the pressure rods 52 of the two pneumatic pressure rod mechanisms 50 are respectively pressed on the two notches 410.

[0030] Reference Figures 1 to 4 The lower mold frame 32 is further provided with a mold shell 33, which encloses the pneumatic pressure rod mechanism 50, the upper mold frame 31, and the lower mold frame 32. Specifically, the mold shell 33 consists of a mold cylinder 331 and an upper shell 332. The upper shell 332 is located above the mold cylinder 331, and an opening 3320 is formed in the middle of the top surface of the upper shell 332. The sidewalls of the opening 3320 are located outside the maximum vertical projection range of the upper mold frame 31 and the lower mold frame 32, ensuring that the upper and lower mold frames can be smoothly lifted by the top mold device 70. The upper shell 332 is also provided with a clearance groove 3321 on each of the two sides of the opening to provide clearance space for the pressure rod of the pneumatic pressure rod mechanism to rotate upward.

[0031] Reference Figure 3 and Figure 4 The aforementioned step 311 is also equipped with a lifting device for driving the upper housing 332 to move up and down. This embodiment shows two lifting devices on the step 311. The lifting devices are lifting cylinders 34, with the cylinder base fixed to the step and the end of the cylinder's extension rod fixedly connected to the bottom surface of the upper housing. When the top mold device 70 pushes the upper mold 41 and lower mold 42 to their highest positions, the lifting cylinder 34 lifts the upper housing 332 until it is aligned with the bottom surface of the lower mold 42, facilitating the transfer of the rolled mold to the conveyor.

[0032] Reference Figure 1 and Figure 5The rotating device 60 includes a rotating shaft 61 and a power mechanism 62. The rotating shaft 61 is connected to the bottom center of the lower mold frame 32. A mounting housing 63 is also fixed on the side wall of the frame 1. The mounting housing 63 covers the outside of the rotating shaft, and the rotating shaft 61 is rotatably inserted into the mounting housing 63 through a bearing 64. In this embodiment, the rotating shaft 61 is preferably T-shaped, wherein the vertical part of the rotating shaft 61 is composed of multiple connecting segments of different diameters, and the diameters of the multiple connecting segments decrease sequentially from top to bottom.

[0033] Reference Figure 5 Two gas channels 65 are provided on the side wall of the rotating shaft 61. Each gas channel has a first gas pipe interface 651 and a second gas pipe interface 652. A first sealed chamber 611 and a second sealed chamber 612 are formed between the rotating shaft 61 and the mounting housing 63, respectively corresponding to and communicating with the first gas pipe interfaces 651 of the two gas channels 65. Specifically, a first sealing element 661 is fixedly installed on the upper and lower parts of one of the first gas pipe interfaces 651 between the rotating shaft 61 and the mounting housing 63, and the first sealing element 661, the rotating shaft 61 and the mounting housing 63 form the first sealed chamber 611; a second sealing element 662 is fixedly installed on the upper and lower parts of the other first gas pipe interface 651 between the rotating shaft 61 and the mounting housing 63, and the second sealing element 662, the rotating shaft 61 and the mounting housing 63 form the second sealed chamber 612. The first sealed chamber 611 and the second sealed chamber 612 each have an air hole 631 on the corresponding side wall of the mounting housing 63, and the two air holes 631 are respectively connected to the air source system.

[0034] To prevent the first sealing element 661 of the first sealed chamber 611 and the second sealing element 662 of the second sealed chamber 612 from moving up and down when air enters through the vent, a support ring 663 is provided between the two first sealing elements 661 and between the two second sealing elements. Each support ring has a corresponding through hole 664 that communicates with the vent 631.

[0035] When the shaft rotates, the two gas channels rotate with the shaft, while the mounting housing remains stationary. The first gas pipe interface of the two gas channels is always connected to its corresponding sealed chamber.

[0036] Reference Figure 4 The two second air pipe interfaces 652 are respectively located on both sides of the top end of the T-shaped rotating shaft 61. Since there are two lifting cylinders 34 and two lever cylinders 51, each second air pipe interface 652 in this embodiment is connected to two air pipes 653, and each air pipe 653 is connected to a solenoid valve. The four solenoid valves are correspondingly connected to the lifting cylinder 34 and the lever cylinder 51. For example: Refer to... Figure 6In this embodiment, a two-position three-way solenoid valve is specifically used. Four air pipes 653 are respectively connected to the A port of the four two-position three-way solenoid valves. The B ports of the two two-position three-way solenoid valves on the same second air pipe interface are respectively connected to the air inlet of the two lifting cylinders 34, and the two C ports are respectively connected to the air outlet of the two lifting cylinders 34. The B ports of the other two two-position three-way solenoid valves are respectively connected to the air inlet of the two pressure rod cylinders, and the two C ports are respectively connected to the air outlet of the two pressure rod cylinders.

[0037] The following functions are achieved through the switching control of solenoid valves: When all two-position three-way solenoid valves are connected to their A and C ports, the two pressure rod cylinders can be controlled to lift upwards to press the pressure rods against the upper mold, while the lifting cylinders act downwards to lower the upper housing until it is aligned with the top surface of the pressure rods; when all two-position three-way solenoid valves are switched to connect their A and B ports, the two pressure rod cylinders can be controlled to pull downwards to release the pressure rods from the upper mold, while the cylinders act upwards to raise the upper housing until it is aligned with the bottom surface of the lower mold.

[0038] Reference Figure 1 The power mechanism 62 includes a driving pulley 621, a driven pulley 622, a connecting belt 623, and a drive motor 624. The drive motor 624 is fixed to the side wall of the frame 1, the driving pulley 621 is mounted on the motor shaft of the drive motor 624, the driven pulley 622 is fixed to the rotating shaft 61, and the driving pulley 621 and the driven pulley 622 are connected by the connecting belt 623.

[0039] Reference Figure 1 Below the lower mold frame 32, a top mold device 70 is also provided. The top mold device 70 includes a top rod 71, a top plate 72, a connecting rod 73, and a top mold cylinder 74. A central hole 610 is provided on the rotating shaft 61 along its central axis. The top rod 71 passes through the central hole 610 and the bottom of the lower mold frame 32 and enters the lower mold frame 32. The top of the top rod 71 is fixedly connected to a top plate 72. The top mold cylinder 74 is provided on the side wall of the frame 1. The piston rod end of the top mold cylinder 74 is connected to the bottom of the top rod 71 through the connecting rod 73.

[0040] Reference Figure 3 and Figure 4 An elastic pad 322 is provided on the inner bottom of the lower mold frame 32, and an annular sealing ring 721 is provided on the bottom surface of the top plate 72. The lower mold frame 32, rubber ring 321, lower mold 42, elastic pad 322, top plate 72 and annular sealing ring 721 form a vacuum chamber. A central through hole 710 is opened in the axial direction of the push rod 71, passing through the top surface of the top plate 72. The upper end of the central through hole 710 is connected to the vacuum chamber. A filter screen 711 is also installed at the upper end of the central through hole 710. A vacuum mechanism is connected to the lower end of the central through hole.

[0041] When producing ordinary ceramics, the pneumatic pressure bar mechanism on the upper mold frame and its outer wall is disassembled, and an integrated mold is installed in the lower mold frame to replace the upper and lower molds. A vacuum mechanism draws air, evacuating the gas inside the evacuation chamber, pressing the mold tightly against the rubber ring. This prevents slippage of the mold during rolling, which would wear the rubber ring and affect the rolling quality of the green body. Furthermore, when producing green bodies with protruding feet at the bottom, the vacuum allows clay to be drawn into the corresponding cavity of the mold, filling the cavity and compensating for poor green body quality caused by incomplete rolling by the roller head. After rolling, the vacuum mechanism releases air, allowing air to fill the evacuation chamber, and the mold can then be separated from the lower mold frame. Therefore, this ceramic rolling forming equipment is used for producing ordinary ceramics and does not require a pneumatic pressure bar mechanism to press the mold.

[0042] During ceramic roll forming, the bottom surface of the upper housing 332 is located above the top surface of the pressure rod 52. The mold shell 33 encloses the pneumatic pressure rod mechanism 50, the upper mold frame 31, and the lower mold frame 32 inside to prevent them from hitting the operators nearby when rotating. After ceramic roll forming, when the upper mold 41 and the lower mold 42 move upward to demold, the extension and retraction of the piston rod of the pneumatic component 51 causes the pressure rod 52 to rotate upward, forming a certain angle with the horizontal plane. The top mold device 70 then pushes the upper mold 41 and the lower mold 42 upward. At the same time, the lifting device pushes the upper housing up until its top surface is aligned with the bottom surface of the lower mold.

[0043] The above-mentioned pneumatic lever mechanism 50 can also use a lever cylinder commonly available on the market.

[0044] The pneumatic lever mechanism 50 shown in the above embodiments is not limited to two; it can also be three or more. When there are three pneumatic lever mechanisms and three lifting cylinders, each second air pipe interface is connected to three air pipes respectively.

[0045] The molds shown in the above embodiments are of a split upper and lower mold type, but the mold of this utility model is not limited to this; it can also be an open-type integrated mold. Similarly, although the mold frame adopts a combination structure of upper and lower mold frames, in other embodiments, the mold frame can also be an integrated mold frame. When an integrated mold frame is used, the steps of the upper mold shell can be directly fixed to the side of the mold frame.

[0046] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
