Description

Technical Field

[0001] This invention relates to the field of ceramic tile processing equipment technology, and in particular to an integrated ceramic tile cutting machine that achieves full-cut edge cutting of ceramic tiles. Background Technology

[0002] In construction and decoration projects, tile laying requires cutting finished tiles to size according to the dimensions to be laid on site. Manual integrated tile cutters have long been the most widely used tile cutting equipment on construction sites due to their advantages such as no external power supply required, high portability, low operating threshold, and controllable processing costs.

[0003] Existing manual integrated tile cutters typically have only a single cutting wheel at the cutting end. The hardened edge of the wheel carves continuous, deep lines on the tile surface, and the machine's built-in crushing mechanism causes the tile to break cleanly along the carved path. However, when starting the cut at the tile edge, the circular contour of the cutting wheel cannot completely conform to the edge face of the tile for a complete cut, often resulting in missing lines at the tile edge and insufficient cutting depth.

[0004] To ensure effective marking on the entire tile, operators typically employ a two-step method: first, make a reverse cut from the starting point on the tile's edge to complete the edge segment; then, proceed forward from the starting point of the cut to complete the entire marking. This method has the following problems: firstly, the operation steps are cumbersome and the cutting efficiency is low; secondly, the two-step process relies entirely on the operator's feel, which can easily lead to misalignment and uneven marking depth; and thirdly, when starting the reverse cut, the blade impacts and cuts inward from the tile's edge, which can easily cause stress damage to the tile's corners, leading to edge cracking and chipping.

[0005] Some existing technologies attempt to improve the cutting effect by using auxiliary wheels (see CN119489510A), but these auxiliary wheels mainly serve a guiding and protective function. The cutting force is limited by the compression design, but the technical problem of cutting the edge of the tile with a single cut has not been solved. Summary of the Invention

[0006] The main objective of this invention is to provide an integrated tile cutting machine that enables full-cut edge cutting of tiles, aiming to solve the problems of reverse pre-cutting, cumbersome operation, and easy misalignment in the existing technology for cutting tile edges.

[0007] To achieve the above objectives, the present invention proposes an integrated tile cutting machine for cutting the edge of a tile in one pass, comprising a cutting machine body, wherein the cutting machine body has a cutting head assembly and a wheel frame mounting base, characterized in that the cutting head assembly comprises:

[0008] Auxiliary front wheel, mounted on the wheel frame mounting base;

[0009] A cutting blade wheel is mounted on the wheel frame mounting base, and the cutting blade wheel and the auxiliary front wheel are spaced back and forth along the cutting direction.

[0010] The vertical height of the lowest point of the auxiliary front wheel is higher than that of the lowest point of the cutting wheel, forming a height difference h. The auxiliary front wheel contacts the tile surface before the cutting wheel and forms a pre-pressure support, so that the cutting wheel smoothly transitions from the edge of the tile to the surface of the tile, and completes the whole continuous cut in a single forward feed.

[0011] In one embodiment, the height difference h ranges from 0.2 mm to 1.5 mm.

[0012] In one embodiment, a gap S is provided between the cutting blade wheel and the auxiliary front wheel along the cutting direction.

[0013] In one embodiment, the interval distance S ranges from 2mm to 10mm.

[0014] In one embodiment, the auxiliary front wheel and the cutting wheel are respectively mounted on the wheel frame mounting base via a rotating connector, so that the cutting wheel and the auxiliary front wheel can rotate about the axis of their respective rotating connectors.

[0015] In one embodiment, the rotating connector is a bolt.

[0016] In one embodiment, a laser alignment groove is provided on the outer peripheral surface of the auxiliary front wheel.

[0017] In one embodiment, the laser alignment groove is a circumferential annular groove surrounding the outer peripheral surface of the auxiliary front wheel.

[0018] In the technical solution of this invention, an auxiliary front wheel is set in front of the cutting wheel, and a fixed height difference is formed between the bottom of the auxiliary front wheel and the bottom of the cutting wheel. During tile cutting, the auxiliary front wheel can contact and pre-press onto the tile surface before the cutting wheel, providing support and guidance for the cutting wheel's entry position. This allows the cutting wheel to smoothly transition from the tile edge to the tile surface without reverse pre-marking. A single forward feed is sufficient to complete a continuous cut from the edge to the inside of the tile, ensuring the integrity and continuity of the marking and improving cutting efficiency. This simplifies the cutting operation process, ensures the integrity and continuity of the cutting marking, avoids the problem of misalignment between two markings, improves the cross-sectional quality of the tile after crushing, and also avoids chipping damage to the tile edge caused by reverse cutting, reducing material waste during tile processing. Simultaneously, a laser alignment groove is set on the outer circumferential surface of the auxiliary front wheel, which facilitates rapid calibration of the laser marking and improves cutting accuracy.

[0029] This invention provides an integrated tile cutting machine that enables full-cut edge cutting of tiles.

[0030] The integrated tile cutting machine for achieving full-cut edge cutting of tiles provided in this embodiment of the invention includes a main frame of the cutting machine, a linear guide rail assembly mounted on the frame, a cutting head assembly slidably mounted on the guide rail assembly, and a pressing operation mechanism. The cutting head assembly is equipped with a wheel assembly structure for forming depth lines on the tile surface. The core improvement of this invention lies in the structural design of this wheel assembly. The conventional structure of the rest of the main body of the cutting machine can refer to the general structure of existing manual integrated tile cutting machines, and will not be described in detail here.

[0031] like Figure 1 As shown, the wheel assembly structure for completing the tile marking operation includes an auxiliary front wheel 10 and a cutting blade wheel 20. The two wheels are arranged at intervals along the cutting direction of the cutting machine. During the actual cutting feed, the auxiliary front wheel 10 is located at the front of the direction of travel, and the cutting blade wheel 20 is located at the rear of the direction of travel. Both are mounted on the wheel frame mounting seat of the cutting head assembly. The wheel frame mounting seat is connected to the pressing mechanism of the cutting head, which can evenly transmit the operating pressure to the two wheels.

[0032] like Figure 2 and Figure 3 As shown, the vertical height of the lowest point of the bottom of the auxiliary front wheel 10 is higher than the vertical height of the lowest point of the bottom of the cutting wheel 20, thus forming a fixed height difference h between the bottoms of the two wheels.

[0033] When actually cutting the edge of a tile, the operator first fixes the cutting machine frame at the position of the tile to be processed, aligning the cutting path with the edge line of the tile to be cut. Then, the operator holds the operating handle of the cutting head and pushes it forward. As the cutting head assembly moves forward along the guide rail, the auxiliary front wheel 10, which is located at the front, contacts the upper surface of the tile first and presses against the tile. At this time, the cutting blade wheel 20 located at the rear corresponds exactly to the edge end face of the tile.

[0034] Since the auxiliary front wheel 10 has been pre-pressed onto the tile surface to form a stable support reference, there is only a small distance h between the bottom of the cutting wheel 20 and the tile surface. As the cutting head continues to advance, the cutting wheel 20 can smoothly climb up along the edge of the tile and transition to the upper surface of the tile, and then directly cut into the surface of the tile to form a continuous scribing line. Only one forward push operation is needed to complete the complete scribing from the edge of the tile to the entire cutting path, without the need for additional reverse pre-scibing operations.

[0035] During the normal planar cutting stage, the cutting wheel 20 cuts completely into the tile surface. At this time, the auxiliary front wheel 10 is suspended in the air and does not contact the tile surface. All the downward pressure is applied to the cutting wheel 20, ensuring that the depth of the cutting line is stable and that the cutting force is not weakened by the support of the auxiliary front wheel 10.

[0036] For example, the height difference h is set between 0.2mm and 1.5mm. This range is the optimal range determined after multiple tests and verifications, taking into account the actual needs of the cutting operation. If the height difference h is too large, the distance between the cutting wheel 20 and the tile surface will be too far. During the feeding process, the cutting wheel 20 will have difficulty climbing smoothly from the edge of the tile to the surface, resulting in incomplete edge cutting and missing lines, and failing to achieve a complete cut. If the height difference h is too small, during normal cutting on the tile surface, the bottom of the auxiliary front wheel 10 will contact or even press against the tile surface, sharing the downward pressure of the cutting wheel 20. This will result in insufficient cutting depth of the cutting wheel 20, affecting the depth and clarity of the lines, and consequently affecting the subsequent crushing effect. By controlling the height difference within this range, it is possible to ensure that the cutting wheel 20 can climb smoothly and cut into the edge, achieving complete line marking on the edge segment, while also ensuring that the auxiliary front wheel 10 does not interfere with the normal operation of the cutting wheel 20 during flat cutting, ensuring uniform line depth.

[0037] In addition, a gap S is provided between the auxiliary front wheel 10 and the cutting blade wheel 20 along the cutting direction. The value of this gap S ranges from 2mm to 10mm. If the gap S is too large, the lever arm of the auxiliary front wheel 10 during pre-load support will be too long. During the feeding process, the lateral force on the auxiliary front wheel 10 will be easily amplified, causing the auxiliary front wheel 10 to shift position, which will affect the straightness of the cutting line and reduce the cutting accuracy. If the gap S is too small, the gap between the two wheels will be insufficient, and mutual interference and friction will easily occur during assembly and rotation. This will increase the resistance of the cutting feed, making the pushing operation more difficult, and will also aggravate the wear of the wheel contact surface, shortening the service life of the equipment. By controlling the gap distance within this range, the stability of the pre-load support can be maximized while ensuring that the two wheels do not interfere with each other, ensuring the accuracy of the cutting line, and also taking into account the compactness of the structure.

[0038] Both the cutting wheel 20 and the auxiliary front wheel 10 have a rotating connector 30 at their axial center positions. The two wheels are respectively mounted on the wheel frame via the rotating connector 30, and both can rotate freely around the axis of the corresponding rotating connector 30. In this embodiment, the rotating connector 30 adopts a bolt structure. The bolt passes through the shaft hole at the center of the wheel body and is locked and fixed to the mounting position on the wheel frame. The wheel body and the bolt have a clearance fit, thereby achieving free rolling of the wheel body. Using a bolt as the rotating connector 30 ensures smooth wheel rotation, effectively reduces rolling resistance during the cutting feed process, makes the scribing process smoother and more uniform, and improves the continuity of the scribing. At the same time, the bolt structure facilitates easy disassembly and assembly, making it convenient for subsequent replacement and maintenance of worn wheels, and also helps control production costs, adapting to the needs of mass production.

[0039] A laser alignment groove 40 is provided on the surface of the auxiliary front wheel 10, and this laser alignment groove 40 is arranged in a ring around the circumferential surface of the auxiliary front wheel 10. Integrated tile cutting machines are usually equipped with a laser marking device to assist operators in aligning the cutting path. The laser line needs to be kept in a straight line with the cutting edge of the cutting wheel 20 to ensure that the marking position is completely consistent with the laser indication position. After setting the ring-shaped laser alignment groove 40 on the auxiliary front wheel 10, the laser line can be projected into the groove during laser calibration. The position of the groove can be quickly matched to the cutting edge position of the cutting wheel 20, greatly improving the convenience and accuracy of laser calibration. The ring-shaped structural design also ensures that the groove can receive the laser line no matter what angle the auxiliary front wheel 10 rotates to, without affecting the calibration operation, adapting to different usage scenarios.

All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
