Description

Technical Field

[0001] This utility model relates to the field of ceramic trimming technology, and in particular to a precision trimming knife set for ceramic tableware. Background Technology

[0002] The production of ceramic tableware typically includes key processes such as throwing, drying, trimming, glazing, and firing. Among these, trimming is a crucial step, as it determines the final shape accuracy, wall thickness uniformity, surface smoothness, and overall weight of the vessel. The value of a fine ceramic tableware piece largely stems from the exquisite craftsmanship demonstrated in the trimming process.

[0003] Currently, the traditional manual trimming method is widely used in the trimming process of ceramic tableware. This involves craftsmen using trimming knives of fixed shapes. One of the biggest problems with this method is the lack of precision and stability. When trimming areas with complex curves, such as the inner wall of a bowl or the edge of a plate with a curved surface, the craftsman's hand stability and experience are crucial in maintaining the optimal contact angle between the blade and the surface of the ceramic piece. Although experienced craftsmen can reduce errors through long-term practice and accumulation, uneven trimming thickness, blade skipping, or excessive thinning in certain areas still exist, making it difficult to fully guarantee product consistency and quality. Furthermore, to trim different parts of the ceramic piece, it is usually necessary to frequently change trimming knives of different shapes, sizes, and angles. This operation not only increases the number of interruptions in the production process and reduces overall work efficiency, but also places higher demands on tool management, requiring the purchase and storage of a large number of trimming knives, increasing production costs and management workload. Therefore, we propose a precision trimming knife set for ceramic tableware. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Currently, the traditional manual trimming method is commonly used in ceramic tableware trimming, where artisans use trimming knives of fixed shapes. One of the biggest problems with this method is insufficient precision and stability. When trimming areas with complex curves, such as the inner wall of a bowl or the edge of a plate with a curved surface, the artisan's hand stability and experience are crucial in maintaining the optimal contact angle between the blade and the surface of the ceramic piece. Although experienced artisans can reduce errors through long-term practice and accumulation, uneven trimming thickness, blade skipping, or excessively thin areas still exist, making it difficult to fully guarantee product consistency and quality. Furthermore, to trim different parts of the ceramic piece, it is usually necessary to frequently change trimming knives of different shapes, sizes, and angles. This operation not only increases the number of interruptions in the production process and reduces overall work efficiency, but also places higher demands on tool management, requiring the purchase and storage of a large number of trimming knives, increasing production costs and management workload.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision trimming knife set for ceramic tableware includes a handle and a replaceable blade. The replaceable blade is installed at the front end of the handle, and a quick-change interface is installed at the front end of the handle. A connecting seat is provided at the end of the replaceable blade, and the connecting seat and the quick-change interface are engaged and locked together.

[0007] Furthermore, the handle is an irregularly shaped handle that conforms to the shape of the hand, and is made of anodized aluminum alloy. A steering module is installed inside the front end of the handle below the quick-change interface.

[0008] Furthermore, the steering module consists of a ball joint and a locking ring. The ball joint is mounted on the top of the locking ring, and the replaceable cutter head can be adjusted to an angle of 0°-15° via the steering module.

[0009] Furthermore, the quick-change interface is a short cylindrical shape, a first release button is provided on one outer wall of the quick-change interface, and three claws are arranged in a circular pattern inside the front end of the quick-change interface.

[0010] Furthermore, each of the claws has a first anti-slip texture on its contact surface, and each claw has a compression spring connected to its rear end, with the compression spring being linked to the first release button.

[0011] Furthermore, a second release button is installed on the outer wall of the connector, and a locking post is provided on one end of the connector that contacts the quick-change interface. The outer wall of the locking post is provided with a second anti-slip texture, and the diameter of the locking post is larger than the circular diameter formed by the three claws in the initial state.

[0012] Furthermore, a connecting rod is provided at the bottom of the inner part of the snap-fit ​​post, and a shrink plate is installed at the end of the connecting rod.

[0013] Furthermore, the second release button is linked to the connecting rod, and the diameter of the expanded retractable plate is the same as the inner diameter of the quick-change interface.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model achieves precise multi-angle adjustment and locking of the blade within the range of 0°-15° through a steering module. This allows craftsmen to pre-adjust and fix the blade to the optimal cutting angle according to the curvature of different parts of the tableware blank. This design fundamentally overcomes the drawback of the traditional method, which relies entirely on the craftsman's feel and experience to maintain the angle. It effectively avoids defects such as uneven thickness of the blank, localized excessive thinness, or blade skipping caused by angle deviation, and greatly ensures the consistency of the product and the quality of the finished product.

[0016] 2. This utility model adopts a highly efficient quick-change interface structure. Through the engagement of the claw at the handle end and the locking post at the cutter head end, combined with the dual linkage design of the first release button and the second release button, the "one-click" quick replacement and connection of the cutter head is realized. This solves the pain point of needing to frequently find and replace a large number of different shaped cutters in the traditional blank repair process, greatly reduces production interruption time, simplifies the operation process, and thus significantly improves the overall work efficiency.

[0026] Example 1

[0027] like Figure 1-4 As shown, this utility model provides a technical solution: a precision trimming knife set for ceramic tableware, including a handle 1 and a replaceable blade 2. The replaceable blade 2 is installed at the front end of the handle 1, and a quick-change interface 101 is installed at the front end of the handle 1. A connecting seat 201 is provided at the end of the replaceable blade 2. The connecting seat 201 and the quick-change interface 101 fit together and engage. A set of knives is equipped with replaceable blades 2 of various shapes (such as arc, triangle, square, etc.). Each replaceable blade 2 has a connecting seat 201 at the end that matches the handle interface. The craftsman does not need to replace the entire tool. He can change the blade in seconds by simply pressing a button, which greatly improves efficiency.

[0028] Example 2

[0029] like Figure 1-4 As shown, the handle 1 is an irregularly shaped handle conforming to the shape of the hand, and is made of anodized aluminum alloy. A steering module 3 is installed inside the front end of the handle 1 below the quick-change interface 101. The steering module 3 consists of a ball joint 301 and a locking ring 302. The ball joint 301 is mounted on the top of the locking ring 302. The replaceable cutter head 2 can be adjusted from 0° to 15° via the steering module 3. Through the universal joint structure, the cutter head can be precisely adjusted to the most suitable cutting angle for the current blank surface and locked at that angle. This ensures that the blade always contacts the blank at the optimal cutting angle, significantly reducing reliance on operator skill and improving the consistency and accuracy of the blank thickness.

[0030] The quick-change interface 101 is a short cylindrical shape. A first release button 102 is provided on one outer wall of the quick-change interface 101. Three jaws 103 are arranged in a circular pattern inside the front end of the quick-change interface 101. Each jaw 103 has a first anti-slip texture 104 on its contact surface. Each jaw 103 has a compression spring connected to its rear end. The compression spring is linked to the first release button 102. The compression spring provides continuous pressure so that each jaw 103 is always locked when the button is not pressed. Pressing the first release button 102 will push an internal wedge block. This wedge block will push the jaws outward, compressing the compression spring and releasing the cutter head.

[0031] A second release button 202 is installed on the outer wall of the connector 201. A locking post 203 is provided on one end of the connector 201 that contacts the quick-change interface 101. A second anti-slip texture 204 is provided on the outer wall of the locking post 203. The diameter of the locking post 203 is larger than the diameter of the circle formed by the three claws 103 in the initial state. A connecting rod 205 is provided at the bottom of the inner side of the locking post 203. A shrink plate 206 is installed at the end of the connecting rod 205. The second release button 202 is linked with the connecting rod 205. The diameter of the shrink plate 206 when it is unfolded is the same as the inner diameter of the quick-change interface 101. When the locking post 203 is inserted into the quick-change interface 101, the three claws 103 lock the locking post 203 under the pressure of the compression spring. When the second release button 202 is pressed, the shrink plate 206 extends and unfolds to prevent the locking post 203 from moving outward.

[0032] The working process of this utility model is as follows: When using a precision trimming knife set for ceramic tableware, the craftsman first selects a suitable replaceable blade head 2 according to the part of the tableware to be trimmed. When installing the knife, the connecting seat 201 at the end of the blade head is aligned with the quick-change interface 101 at the front end of the handle 1 and inserted directly. The locking pin 203 on the connecting seat 201 will open the three locking claws 103 inside the interface. When the anti-slip groove on the locking pin 203 moves to the position of the locking claw 103, the locking claw 103 quickly rebounds under the pressure of the internal compression spring. Then, the second release button 202 is pressed, and the shrink plate 206 inside the locking pin 203 unfolds, completing the automatic locking and fixing of the blade head.

[0033] After the cutter head is installed, the craftsman can rotate the handle 1 and steplessly adjust the angle of the cutter head through the steering module 3 at its front end to match the best cutting angle of the blank surface. After adjustment, tighten the locking ring 302 to fix the ball joint 301, and then start trimming the blank. During this process, the locked angle can ensure that the blade always contacts the blank at the most ideal angle, thereby trimming a blank with uniform thickness and smooth surface.

[0034] When it is necessary to change the cutter head to process different parts, the craftsman can press the first release button 102 on the handle 1 and the second release button 202 on the cutter head simultaneously or separately. Pressing the first release button 102 will push the internal wedge block to push the pawl 103 outward and release the lock on the locking post 203. Pressing the second release button 202 will push the end shrink plate 206 to retract through the connecting rod 205, moving the locking post 203 outward from the interface, thereby realizing the quick and effortless separation of the cutter head and preparing for the replacement of the next cutter head.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
