Description

Technical Field

[0001] This invention relates to the field of ceramic tile production technology, and in particular to an intelligent edge trimming machine for ceramic tile blanks. Background Technology

[0002] Ceramic tiles are a type of building or decorative material made of refractory metal oxides and semi-metal oxides through grinding, mixing, pressing, glazing, and sintering. They are resistant to acids and alkalis and are made of porcelain or stone. The raw materials are mostly a mixture of clay, quartz sand, etc.

[0003] An edge trimming machine is a device specifically developed for online corner trimming and edge trimming of ceramic tiles. Existing edge trimming equipment technology uses multiple motors and multiple grinding discs. Because the position of the grinding discs is fixed during edge trimming, the edge of the tile must be parallel and equidistant from the grinding disc's trajectory as the tile moves. However, to maintain this parallelism and equidistant alignment, the tile needs to be dried to increase its strength and ensure centering. This is difficult to adapt to the original tile blank. If the tile blank is slightly misaligned, edge trimming cannot proceed properly. This places extremely high demands on the precision of the production line, resulting in low edge trimming efficiency. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an intelligent edge trimming machine for ceramic tile blanks, comprising a frame, left and right edge trimming devices, and front and rear edge trimming devices. The frame is provided with a first support frame, a second support frame, and a third support frame.

The first sliding mechanism is symmetrically arranged on the first support frame along the length of the frame, and the cutter head assembly is mounted on the first sliding mechanism. The front and rear edge trimming devices include a second sliding mechanism and a cutter head assembly. Both the second and third support frames are provided with a second sliding mechanism, and the cutter head assemblies are symmetrically mounted on the second sliding mechanisms of the second and third support frames.

[0005] The first sliding mechanism includes a first cutter head bracket, a first ball screw, and a first geared motor. The first cutter head bracket slides on a first support frame via a track. The first ball screw is connected to the rotating end of the first geared motor via a coupling. The first ball screw drives the first cutter head bracket to slide longitudinally.

[0006] The second sliding mechanism includes a second cutter head bracket, a third cutter head bracket, a second ball screw, a second geared motor, and a third geared motor. The second cutter head bracket slides longitudinally on a second or third support frame via a track. The second geared motor drives the second cutter head bracket to slide via a belt. The third cutter head bracket slides laterally on the second cutter head bracket via a track. The third geared motor is connected to the second ball screw, and the second ball screw drives the third cutter head bracket to slide.

[0007] The cutter head assembly includes a cutting motor, a V-shaped cutter, and a laser displacement sensor.

[0024] Reference Figure 2-3The first sliding mechanism 2 includes a first cutter head support 21, a first ball screw 22 and a first geared motor 23. The first cutter head support 21 slides on the first support frame 11 via a track. The first ball screw 22 is connected to the rotating end of the first geared motor 23 via a coupling 24. The first ball screw 22 drives the first cutter head support 21 to slide longitudinally.

[0025] Reference Figure 4-6 The second sliding mechanism 3 includes a second cutter head support 31, a third cutter head support 32, a second ball screw 33, a second geared motor 34, and a third geared motor 35. The second cutter head support 31 slides longitudinally on the second support frame 12 or the third support frame 13 via a track. The second geared motor 34 drives the second cutter head support 31 to slide via a belt 36. The third cutter head support 32 slides laterally on the second cutter head support 31 via a track. The third geared motor 35 is connected to the second ball screw 33, and the second ball screw 33 drives the third cutter head support 32 to slide.

[0026] Reference Figure 7-8 The cutter head assembly 4 includes a cutting motor 41, a V-shaped cutter 42, and a laser displacement sensor 43. The cutting motor 41 is fixed vertically on the motor mounting base 44, and the V-shaped cutter 42 is connected to the lower rotating part of the cutting motor 41. A sensor plate 45 is installed at the bottom of the motor mounting base 44, and the laser displacement sensor 43 is installed on the sensor plate 45. The data measured in real time by the laser displacement sensor 43 is transmitted to the PLC through the AD data module. After calculation by the PLC, pulses are output to control the feed of each motor, thereby achieving real-time tracking.

[0027] In this embodiment, refer to Figure 1 Several rollers 101 are arranged along the length of the frame 1. The rollers 101 are connected to the servo motor through synchronous teeth and synchronous belt.

[0028] In this embodiment, refer to Figure 7 and 9 The cutter head assembly 4 is equipped with a height adjustment assembly 5, which includes a first dovetail slide 51, a second dovetail slide 52, an adjusting screw 53, and an adjusting handle 54.

[0030] This invention trims the edges of the brick blank 6 using left and right trimming devices and front and rear trimming devices. The first sliding mechanism 2 of the left and right trimming devices can drive the cutter head assembly 4 to move longitudinally, and the second sliding mechanism 3 of the front and rear trimming devices can drive the cutter head assembly 4 to move longitudinally and laterally. Non-contact tracking measurement is performed using the laser displacement sensor 43 on the cutter head assembly 4, which does not damage the surface of the ceramic tile. The cutter head assembly 4 is equipped with a precision V-shaped cutter 42, which is suitable for ceramic tile blanks produced by the press of the ceramic production line. The trimming cutter can automatically follow the edge to be processed according to the product. The position of the product does not need to be absolutely straight when it moves or stops. It can also ensure trimming within a certain range of deviation.

[0031] Compared with existing technologies:

[0032] The existing X-direction cutter is a circular grinding disc, which requires 4 cutting motors. The X-direction cutter of this invention adopts a V-shaped cutter, which requires 2 cutting motors, reducing the number of motors by 2 and shortening the wire frame length.

[0033] The existing Y-direction cutting tool is a V-shaped cutting tool, which requires one cutting motor, but only processes two edges on one face. The Y-direction cutting tool of this invention adopts a V-shaped cutting tool, which requires two cutting motors, but ensures that all four edges on the left and right end faces can be processed.

[0034] The existing method of installing X-direction cutters involves using four cutting motors in the X direction, all of which are fixed on both sides of the production line frame and cannot be moved. This invention uses two cutting motors in the X direction and installs them on a slide rail mechanism on the production line frame, allowing the X-direction cutters to slide in the X direction to adapt to different brick blank specifications.

[0035] The existing method of installing the Y-direction cutter is to use one cutting motor in the Y direction and install it on the gantry above the line frame. The present invention uses two cutting motors in the Y direction and installs them on two left and right slide rail mechanisms above the production line frame, which can slide in the X and Y directions to adapt to different brick blank 6 specifications.

[0036] Existing trimming equipment lacks a following function. This invention installs a laser sensor next to the cutting tool, which can measure the distance in real time and realize automatic following of the brick edge that needs to be processed, thereby ensuring that the brick edge can be processed 100% when it moves or stops.

[0037] In summary, the above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Anyone skilled in the art can readily implement the present invention based on the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, based on the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
