Description

Technical Field

[0001] The utility model relates to the field of ceramic bottle production, in particular to a cutting mechanism for cutting and shaping ceramic clay blanks and ceramic products. Background Art

[0002] To ensure the manufacturing quality of ceramic containers, the blanks of the container main body and the upper opening of the container are separately molded and trimmed, and then bonded together for firing. To ensure that the bonding between the main body and the upper opening has better molding quality, when the main body blank is molded separately, its upper end is still molded together with the upper opening to be cut off. After the main body blank is formed, the excess part of its upper end needs to be cut off with a cutting knife, so that the upper end of the main body blank forms a smooth and flat opening for bonding the blank of the upper opening. In addition, before or after firing, some ceramic products usually need to be cut to form an annular shape on their outer end surface, so that the outer side of the molded product has an annular molding groove.

[0003] When cutting ceramic clay or ceramic products, manual cutting results in high workload, low efficiency, and unstable cutting quality. To address these issues, a tool for cutting the bottle mouth of a ceramic blank is disclosed in the prior art. A horizontally rotatable turntable is provided on a base for placing the bottle blank, allowing the bottle blank to be rotated and cut with a cutting blade. A support rod is laterally provided above one side of the turntable via a support member. The support rod provides support for the cutting blade via a horizontal support surface, replacing manual lifting. During use, a worker places the cutting blade on the support surface and applies a certain downward force to keep the cutting blade at the same height. Cutting is completed simply by advancing the blade as the bottle blank rotates.

[0004] After adopting the above-mentioned tooling, although the cutting quality is more stable and the efficiency is higher than manual cutting, it is necessary to manually apply pressure to the support rod to cut the ceramic mud blank, which is inconvenient to operate and has low cutting efficiency. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a cutting mechanism for cutting and shaping ceramic clay blanks and ceramic products, so as to solve the problems of inconvenient operation and low cutting efficiency of the existing cutting devices.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A cutting mechanism for cutting and shaping ceramic clay and ceramic products, comprising a driving motor and a tool holder turntable connected to the output end of the driving motor, a plurality of tool mounting racks centered on the tool holder turntable and arranged in the radial direction of the tool holder turntable are installed on the lower end surface of the tool holder turntable, each tool mounting rack can slide and be positioned in the radial direction of the tool holder turntable under the drive of a tool holder driving mechanism, a cutting tool can be detachably installed at the lower end of each tool mounting rack, the installation heights of the various cutting tools are consistent and in the same horizontal plane, and the blades of the cutting tools are arranged toward the center of the tool holder turntable, and the blade end forms a cutting space for cutting the upper end of the clay; the driving motor and the tool holder driving mechanism are both connected to a controller, and the controller can control the start and stop of the driving motor and the tool holder driving mechanism. In this way, a cutting mechanism is used to replace the cutting knife in the existing ceramic bottle mouth cutting tool. The cutting mechanism includes a tool holder turntable, a tool mounting frame, and a cutting tool. When cutting, the tool holder turntable drives the tool mounting frame to rotate. At the same time, each tool mounting frame can move radially, so as to meet the cutting needs of ceramic clay or ceramic products of different sizes. When cutting, by controlling the radial movement of the cutting tool and the rotation of the tool holder turntable, it is possible to adapt to different cutting needs and accurately control the cutting depth. The multiple cutting tools used, and the cutting tools are at the same installation height and the same plane, are cut synchronously by multiple cutting tools at one time. Compared with cutting with one tool, the cutting is faster and more efficient. In addition, for the demand for overall cutting at the upper end, the cutting edge formed after cutting is smoother, the subsequent bonding is more convenient, and the molding quality is higher.

[0008] Furthermore, a positioning mechanism connected to the tool holder turntable and used to position the upper end of the workpiece is provided in the middle of the tool holder turntable. The positioning mechanism is placed in the space enclosed by the tool mounting frame and includes a central transmission disk. The central transmission disk is mounted at the center of the lower end of the tool holder turntable through a sleeve. A plurality of vertically arranged positioning arms are mounted on the central transmission disk. A driving assembly connected to the controller is connected to the sleeve. The controller can control the driving assembly to drive all positioning arms to slide and position along the radial direction of the central transmission disk, thereby achieving synchronous gathering or synchronous separation. In this way, after a positioning mechanism is provided in the middle of the tool holder turntable with an empty sleeve at its lower end, the positioning mechanism can position the upper end of the workpiece to be cut (i.e., ceramic clay blank or ceramic product), so that when the workpiece is cut, the upper end of the ceramic clay blank or ceramic product will not be offset, thereby affecting the cutting quality. After the cutting is completed, the positioning arms are synchronously gathered, which can facilitate separation from the cut ceramic clay blank or ceramic product. Specifically, the positioning arm on the positioning mechanism is also set to a structure that can be closed and separated, which can also meet the positioning needs of ceramic clay blanks or ceramic products with different diameters of the inner space, and will not interfere with the assembly and movement position of the cutting tool on the outside. At the same time, compared with the method of clamping and positioning the outside of the workpiece, this positioning method is more convenient for positioning. For ceramic clay blanks or ceramic products with irregular upper ends, the support positioning method is more stable.

[0009] Furthermore, the central transmission disc is provided with multiple directional guides centered around the center of the central transmission disc. Each directional guide is equipped with a corresponding translation slider. The directional guides are radially arranged along the central transmission disc, and the positioning arms are fixedly connected to the translation sliders. Thus, the directional guides and translation sliders on the central transmission disc ensure the sliding direction of each positioning arm, providing greater stability during sliding. The connection assembly, in conjunction with the drive assembly, drives the synchronous radial movement of each positioning arm.

[0010] Furthermore, the tool mounting bracket is vertically arranged, with both upper and lower ends horizontally bent toward the center of the tool holder turntable. The upper end is fixedly connected to the tool holder turntable, and the lower end is fixedly connected to the cutting tool via a fastener. In this way, the upper end of the tool mounting bracket is horizontally bent, which facilitates the fit and fixation between the tool holder turntable and the lower end is horizontally bent, which facilitates the installation of the cutting tool.

[0011] Furthermore, the tool holder turntable is fixedly mounted with multiple radially arranged guide rails, each of which is equipped with a corresponding guide slider. These sliders are fixedly connected to the corresponding tool mounting bracket. The tool holder drive mechanism is mounted on the outside of the corresponding guide slider and is capable of driving the sliders for radial movement and positioning. In this way, the guide rails and guide sliders ensure more stable movement and guidance of the tool mounting bracket, while the mounting base provides support for the tool holder drive mechanism. The guide blocks convert the rotational force output by the tool holder drive mechanism into movement, resulting in a compact overall structure.

[0012] Furthermore, a horizontal support plate is provided on the tool rest turntable, the drive motor is fixedly mounted on the horizontal support plate, and the output shaft of the drive motor passes through the horizontal support plate and is connected to the tool rest turntable. In this way, the horizontal support plate can provide sufficient support for the tool rest turntable and the transmission mechanism.

[0013] Furthermore, the drive assembly is mounted on the horizontal support plate and connected to each positioning arm via a connecting assembly. The connecting assembly includes: a rotating mechanism connected to the drive assembly so as to rotate under the drive of the drive assembly; a plurality of connecting rods, each of which is provided in a one-to-one correspondence with the plurality of positioning arms and rotatably connected to the positioning arms. The plurality of connecting rods are rotatably connected to the rotating mechanism, and the rotating mechanism drives the corresponding positioning arm to move by connecting to each connecting rod. In this way, the drive assembly is also mounted on the horizontal support plate, and the structure is compact. The drive assembly is simple in structure, and the movement of multiple positioning arms can be achieved using only one drive, resulting in a compact overall structure.

[0019] like Figure 1-Figure 3As shown, the cutting mechanism for cutting and forming ceramic clay and ceramic products disclosed in this embodiment is installed on a lifting mechanism, which can move up and down and be positioned with the lifting mechanism, including a driving motor and a tool holder turntable 2 connected to the output end of the driving motor. A plurality of tool mounting brackets 3 are installed on the lower end surface of the tool holder turntable 2, centered on the center of the tool holder turntable 2 and arranged along the radial direction of the tool holder turntable 2. Each tool mounting bracket 3 can slide and be positioned in the radial direction of the tool holder turntable 2 under the drive of a tool holder driving mechanism 5. A cutting tool 4 can be detachably installed at the lower end of each tool mounting bracket 3. The installation heights of the various cutting tools 4 are consistent and in the same horizontal plane, and the blade of the cutting tool 4 is set toward the center direction of the tool holder turntable 2, and the blade end forms a cutting space for cutting the upper end of the clay blank; the driving motor and the tool holder driving mechanism 5 are both connected to a controller (not shown in the figure), and the controller can control the start and stop of the driving motor and the tool holder driving mechanism 5. The cutting mechanism includes a tool holder turntable 2, a tool mounting frame 3, and a cutting tool 4. During cutting, the tool holder turntable 2 drives the tool mounting frame 3 to rotate. At the same time, each tool mounting frame 3 can move radially, thereby meeting the cutting requirements of ceramic clay or ceramic products of different sizes. During cutting, by controlling the radial movement of the cutting tool and the rotation of the tool holder turntable, it can adapt to different cutting requirements and accurately control the cutting depth. The use of multiple cutting tools 4, and the cutting tools 4 being at the same installation height and the same plane, can ensure that an annular incision is formed after cutting, and the cutting efficiency is high, and the cutting process can be completed within a few seconds.

[0020] The cutting tool 4 in this embodiment can be made of metal material or non-metal material (such as diamond).

[0021] During the cutting process, if the ceramic clay or ceramic product is cut directly by controlling the cutting tool 4 to rotate around the cutting position of the bottle mouth and move radially, the cut position has no support during the cutting process and is prone to tilting during the cutting process, while the cutting height of the cutting tool 4 remains unchanged, which will affect the cutting quality. Based on this, it is necessary to set a positioning mechanism to position the bottle mouth: a positioning mechanism 9 is also provided in the middle of the tool holder turntable 2, which is connected to the tool holder turntable 2 and is used to position the upper end of the workpiece. The positioning mechanism 9 is placed in the space enclosed by the tool mounting frame 3 and includes a central transmission disk 91. The central transmission disk 91 is hollowly sleeved at the center position of the lower end of the tool holder turntable 2 through a sleeve. A plurality of vertically arranged positioning arms 92 are installed on the central transmission disk 91. A drive assembly connected to the controller is connected to the sleeve. The controller can control the drive assembly to drive all positioning arms 92 to slide along the radial direction of the central transmission disk 91 to achieve synchronous gathering or synchronous separation. In this way, after a positioning mechanism 9 is provided in the middle of the tool holder turntable 2 and is hollowly sleeved at its lower end, the positioning mechanism can position the upper end of the ceramic clay blank or ceramic product so that when cutting, the upper end of the ceramic clay blank or ceramic product will not be offset, which would affect the cutting quality. The positioning arm on the positioning mechanism is also configured to have a structure that can be closed and separated, which can also meet the positioning requirements of ceramic clay blanks or ceramic products with different calibers. The positioning method for the inside of the bottle will not interfere with the assembly and movement position of the cutting tool 65 on the outside. At the same time, compared with the clamping positioning method for the outside of the bottle mouth, this positioning method is more convenient for positioning. For ceramic blanks with irregular upper ends, the open positioning method is more stable.

[0022] Furthermore, the drive assembly is connected to each positioning arm 92 through a connecting assembly. When the motor of the drive assembly rotates forward or reverses, the connecting assembly connected thereto simultaneously drives each positioning arm 92 to move in the radial direction of the central transmission disk 91. A plurality of directional guides are provided on the central transmission disk 91 with the center of the central transmission disk 91 as the center of the circle. A translation slider that cooperates with the directional guide is provided on each directional guide. The directional guide is arranged radially along the central transmission disk 91, and the positioning arm 92 is fixedly connected to the translation slider. Specifically, the structure of the drive assembly and the connecting assembly is the prior art, such as the drive assembly and the connecting assembly structure of the gripping device disclosed in the application number 2019219780751. The directional guides and the translation slider provided on the central transmission disk 91 can ensure the sliding direction of each positioning arm 92, making it more stable when sliding. After the provided connecting assembly cooperates with the drive assembly, it can drive each positioning arm 92 to move radially synchronously.

[0023] Furthermore, the tool mounting frame 3 is arranged vertically, and both the upper and lower ends are horizontally bent toward the center of the tool holder turntable 2. The upper end is fixedly connected to the tool holder turntable 2, and the lower end is provided with a tool assembly hole. The cutting tool 4 is inserted into the tool assembly hole, with the end extending out of the tool assembly hole and fixed to the tool mounting frame 3 by fasteners. In a specific implementation, the cutting tool can be directly placed at the lower end of the tool mounting frame 3 and fixed by fasteners. In this way, after the upper end of the tool mounting frame 3 is horizontally bent, it is convenient to fit and fix it with the tool holder turntable 2. After the lower end is horizontally bent, the tool assembly hole is deeper, which is convenient for increasing the friction between the cutting tool 4 and the tool mounting frame 3 after assembly, making it more stable and less likely to break after long-term use. The tool assembly hole passes through the horizontally bent portion of the lower end and is arranged along the length direction of the horizontally bent portion. A plurality of threaded holes for fasteners to pass through are provided in the horizontally bent portion, so that the cutting tool 4 is also more convenient to replace.

[0024] Furthermore, a plurality of radially arranged guide rails 21 are fixedly mounted on the tool holder turntable 2. Each guide rail 21 is provided with a guide slider 22 that matches it. A guide block 6 is provided between the guide slider 22 and the corresponding tool mounting frame 3, with its upper and lower ends fixedly connected to the guide slider 22 and the tool mounting frame 3 respectively. A threaded hole is provided in the middle of the guide block 6. A mounting seat 7 is fixedly mounted on the tool holder turntable 2 and on one side of each tool mounting frame 3. The tool holder drive mechanism 5 is fixedly mounted on the mounting seat 7, and the output end of the tool holder drive mechanism 5 passes through the mounting seat 7 and is threadedly engaged with the threaded hole of the guide block 6. In this way, the guide rails 21 and guide slider 22 can make the tool mounting frame 3 move more stably and guide it, while the mounting seat 7 can provide support for the tool holder drive mechanism 5. The guide block 6 can convert the rotational force output by the tool holder drive mechanism 5 into movement, and the overall structure is compact.

[0025] Furthermore, a horizontal support plate 1 is provided on the tool holder turntable 2, and the drive motor is fixedly mounted on the horizontal support plate 1. The output shaft of the drive motor passes through the horizontal support plate 1 and is connected to the tool holder turntable 2. In this way, the horizontal support plate 1 can provide sufficient support for the tool holder turntable 2 and the transmission mechanism.

[0026] Furthermore, the drive assembly (not shown) is mounted on the horizontal support plate 1. The drive assembly is connected to each positioning arm 92 via a connecting assembly. The connecting assembly includes a rotation mechanism connected to the drive assembly for rotation under the drive of the drive assembly; and a plurality of connecting rods, each corresponding to each of the positioning arms 92 and rotatably connected to each of the positioning arms 92. The plurality of connecting rods are each rotatably connected to the rotation mechanism, and the rotation mechanism drives the corresponding positioning arm 92 to move by connecting to each of the connecting rods. In this way, the drive assembly is also mounted on the horizontal support plate 1, resulting in a compact structure. The provided drive assembly has a simple structure, and a single drive is used to achieve movement of multiple positioning arms 92, resulting in a compact overall structure.

[0027] In this embodiment, the side end of the horizontal support plate 1 is connected to the lifting mechanism, and a protective cover 8 is provided on the horizontal support plate 1. The drive assembly and the drive motor are both mounted on the horizontal support plate 1 and housed within the protective cover 8. The protective cover 8 can protect the various transmission devices and enhance the safety performance of the product.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the present invention that do not depart from the purpose and scope of the technical solution of the present invention should be included in the scope of the claims of the present invention.
