Description

Technical Field

[0001] This invention relates to the field of artificial stone slab sawing technology, specifically to a sawing device for processing artificial stone slabs. Background Technology

[0002] Traditional clamping devices for artificial stone slabs typically have fixed clamping pressures or require manual adjustment, making it impossible to adapt to the thickness of the slab. For thicker slabs, insufficient clamping pressure can cause the slab to shift due to vibration or lateral forces during sawing, resulting in a deviation from the preset cutting path and affecting dimensional accuracy. For thinner slabs, excessive clamping pressure can easily lead to surface damage or internal cracks due to over-compression, especially for brittle artificial stone materials. This "one-size-fits-all" clamping method makes it difficult for the same equipment to process slabs of different thicknesses, requiring frequent replacement or adjustment of clamping components.

[0003] During the sawing process of artificial stone slabs, when the saw blade approaches the end of the slab, the uncut portion loses sufficient support and is prone to stress concentration under the shearing force and vibration of the saw blade. Traditional sawing devices lack a pre-pressure protection mechanism for the end, which often leads to defects such as edge chipping and cracking at the end of the sawing process, seriously affecting the flatness of the cut surface. Even if some devices attempt to set auxiliary supports at the end, they are mostly fixed structures that cannot be linked with the sawing progress, and the support force cannot match the fixed pressure at the front end, making it difficult to effectively offset stress concentration and still unable to completely solve the problem of end chipping. Summary of the Invention

[0004] The purpose of this invention is to provide a sawing device for processing artificial stone slabs, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sawing device for processing artificial stone slabs, comprising: a conveying structure, an adaptive adjustment device, and a fixing device; the conveying structure is capable of conveying artificial stone blanks; the adaptive adjustment device is disposed on the top surface of one end of the conveying structure, and the adaptive adjustment device is capable of adaptively fixing artificial stone slabs of different thicknesses with appropriate pressure; the fixing device is disposed at the center of the front end of the adaptive adjustment device; and the fixing device can cooperate with the adaptive adjustment device to saw half of the artificial stone slab laterally through the adaptive adjustment device, and the adaptive adjustment device is in contact with the power signal source of the fixing device, thereby pre-pressing and fixing the top end of the remaining unsawed half of the artificial stone blank, and the pressure of the pre-pressing and fixing is the same as the pressure of the adaptive adjustment device on the artificial stone blank, thereby preventing the end of the artificial stone slab from cracking.

[0006] Preferably, for conveying the artificial stone slabs, the conveying structure includes: a bearing plate, a roller conveyor belt, and stone slab support platforms. The bearing plate is used to support the connecting components on the top surface; the roller conveyor belt is located at one end of the top surface of the bearing plate; there are two stone slab support platforms, located at the other end of the top surface of the bearing plate, and there is a certain distance between the two stone slab support platforms.

[0007] Preferably, for sawing the artificial stone slab, the adaptive adjustment device includes: a first portal-shaped support plate, a cylindrical limiting cylinder, a second portal-shaped support plate, a first electric push rod, a connecting rod, a fixing rod, a three-section electric push rod, a high-speed spindle motor, a saw blade, a trigger rod, a drive assembly, a first elastic pressure plate, and a first pressure sensor.

A rod is disposed at the pushing end of the first electric push rod; a fixed rod is disposed at the bottom end of the connecting rod, and the fixed rod extends towards the rear end of the bottom of the connecting rod; a three-section electric push rod is disposed at the rear end of the bottom surface of the fixed rod; a high-speed spindle motor is disposed at the pushing end of the three-section electric push rod; a saw blade is disposed at the rotating end of the high-speed spindle motor; a trigger rod is disposed at the right end of the front side of the outer wall of the high-speed spindle motor; a drive assembly is disposed at the front end of the top face near the first portal support plate, and the two moving ends of the drive assembly are respectively sleeved in two cylindrical limiting cylinders; there are two first elastic pressure plates, which are respectively disposed at the two moving ends of the drive assembly; a first pressure sensor is embedded in the center of the bottom surface of one of the first elastic pressure plates.

[0008] Preferably, the connecting rod drives the fixed rod to move synchronously, so that the three-section electric push rod approaches the blank. The three-section electric push rod drives the high-speed spindle motor to move forward until the saw blade contacts the part of the blank to be cut. The high-speed spindle motor starts and drives the saw blade to rotate at high speed for transverse sawing.

[0009] Preferably, for fixing the artificial stone blank and the finished artificial stone slab, the driving assembly includes: a rack, a third portal-shaped support plate, bearing seats, a rotating rod, a gear, an eccentric cam, a first connecting rod, a second connecting rod, a third connecting rod, and a pressure rod. The rack is located at the top end of the front side of the outer wall of the connecting rod; the third portal-shaped support plate is located at the front end near the top surface of the two first portal-shaped support plates; there are two bearing seats, symmetrically arranged at the left and right ends of the rear side of the top of the outer wall of the third portal-shaped support plate; the rotating rod is sleeved in the two bearing seats, and the rotating rod can rotate through the two bearing seats; the gear is located at the left end of the center of the rotating rod, and the gear meshes with the rack; the eccentric cam... There are two eccentric cams, each located at one end of the rotating rod; two first connecting rods, each located at the eccentric end of the two eccentric cams; two second connecting rods, each located at one end of the outer wall of the two first connecting rods via a first bearing; two third connecting rods, each located at one end of the outer wall of the two second connecting rods via a second bearing; and two pressure rods, each located at the bottom end of the two third connecting rods. The two pressure rods are respectively fitted into two cylindrical limiting cylinders, and the two pressure rods can move up and down within the two cylindrical limiting cylinders, with each pressure rod being fixedly connected to the center of the top surface of the two first elastic pressure plates.

[0010] Preferably, the first electric push rod pushes the connecting rod to drive the rack and pinion gear to rotate, thereby causing the rotating rod to rotate and drive the two eccentric cams to drive the two pressure rods to move downward in the two cylindrical limiting cylinders through the two first connecting rods, the two second connecting rods, and the two third connecting rods, respectively, so that the two pressure rods drive the two first elastic pressure plates to move downward.

[0011] Preferably, for fixing the cut end of the artificial stone slab, the fixing device includes: a support plate, a second electric push rod, a second elastic pressure plate, a second pressure sensor, a connecting plate, a fixing block, an elongated cylinder, a spring, and a contact sensor. The support plate is disposed at the front end of the top of a first portal-shaped support plate; the second electric push rod is disposed at one end of the bottom surface of the support plate; the second elastic pressure plate is disposed at the pushing end of the second electric push rod; the second pressure sensor is embedded in the center of the bottom surface of the second elastic pressure plate, and the second pressure sensor is electrically connected to the first pressure sensor; the connecting plate is disposed at the center of the front side of the outer wall of the support plate; the fixing block is disposed at the front end of the bottom surface of the connecting plate; the elongated cylinder is disposed at one end of the fixing block, and the elongated cylinder extends towards the front end of the fixing block; the spring is disposed at one end inside the elongated cylinder; the contact sensor is disposed at one end of the spring, and the contact sensor is looped around the other end inside the elongated cylinder, and the contact sensor can move along the inner wall of the elongated cylinder.

[0012] Preferably, when the saw blade cuts to half the transverse position of the blank, the trigger rod on the high-speed spindle motor contacts the contact sensor inside the elongated cylinder. The contact sensor adapts to the movement trajectory of the trigger rod through spring deformation and sends a start signal to the second electric push rod.

[0013] Preferably, after receiving a signal, the second electric push rod drives the second elastic pressure plate to move downward, pre-pressing the top of the cut surface of the remaining unsawn blank. The pre-pressing pressure is made consistent with the fixed pressure by feedback adjustment between the second pressure sensor and the first pressure sensor.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The adaptive adjustment device, through the linkage design of the eccentric cam and linkage mechanism in the drive component, combined with the deformation characteristics of the first elastic pressure plate, can automatically adjust the fixed pressure according to the thickness of the artificial stone slab: for thicker slabs, it provides sufficient pressure to prevent deviation during sawing; for thinner slabs, it avoids cracking caused by excessive compression through adaptive pressure, effectively solving the problems of thick plate deviation and thin plate damage caused by the non-adjustable pressure in traditional fixed pressure, and significantly improving the adaptability and versatility of the device for artificial stone slabs of different thicknesses.

[0016] 2. The fixing device and the adaptive adjustment device work together. When the artificial stone slab is cut to half, the trigger rod contacts the contact sensor and drives the second elastic pressure plate to pre-press the top of the cut surface of the remaining uncut part. The second pressure sensor uses the pressure value of the first pressure sensor as a reference to ensure that the pre-pressing pressure is consistent with the adaptive fixing pressure, effectively offsetting the stress concentration at the end of the sawing, avoiding the problem of easy breakage at the end in traditional sawing, and significantly improving the flatness of the cut surface and the quality of the finished product.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-13This invention provides a sawing device for processing artificial stone slabs, comprising: a conveying structure 1, an adaptive adjustment device 2, and a fixing device 3. The conveying structure 1 conveys the artificial stone blank to the top surface of two stone slab support platforms 13 before fixing and sawing. The adaptive adjustment device 2 is located on the top surface of one end of the conveying structure 1 and can adaptively fix the pressure on artificial stone slabs of different thicknesses. This adaptive adjustment device 2 provides adaptive pressure fixation for artificial stone slabs of different thicknesses, exhibiting a certain degree of versatility and preventing thicker artificial stone slabs from shifting during sawing. Furthermore, the adaptive pressure adjustment can prevent excessive pressure from cracking thinner artificial stone slabs, thereby improving cutting quality; the fixing device 3 is located at the front center of the adaptive adjustment device 2; and the fixing device 3 can cooperate with the adaptive adjustment device 2 to saw half of the artificial stone slab horizontally through the adaptive adjustment device 2, and the adaptive adjustment device 2 and the power signal source of the fixing device 3 are in contact, thereby pre-pressing and fixing the top of the remaining unsawed artificial stone blank. The pressure of the pre-pressing and fixing is the same as the pressure of the adaptive adjustment device 2 on the artificial stone blank, thereby preventing the end of the artificial stone slab from cracking and improving cutting quality.

[0033] As a preferred option, further, such as Figure 2 As shown, the conveying structure 1 includes: a bearing plate 11, a roller conveyor belt 12, and a stone slab support platform 13. The bearing plate 11 is used to support the connecting parts on the top surface, providing bearing and support for the connecting parts on the top surface. The roller conveyor belt 12 is set at one end of the top surface of the bearing plate 11, and the roller conveyor belt 12 can convey the artificial stone blank. There are two stone slab support platforms 13, which are set at the other end of the top surface of the bearing plate 11, and there is a certain distance between the two stone slab support platforms 13. The distance between the two stone slab support platforms 13 provides cutting space for the saw blade 29.

[0034] As a preferred option, further, such as Figure 3 and Figure 4As shown, the adaptive adjustment device 2 includes: a first portal-shaped support plate 21, a cylindrical limiting cylinder 22, a second portal-shaped support plate 23, a first electric push rod 24, a connecting rod 25, a fixing rod 26, a three-section electric push rod 27, a high-speed spindle motor 28, a saw blade 29, a trigger rod 210, a drive assembly, a first elastic pressure plate 221, and a first pressure sensor 222. There are two first portal-shaped support plates 21, symmetrically arranged above the center of the top surface of the two stone slab support platforms 13. The two first portal-shaped support plates 21 provide crucial support for the adaptive adjustment device 2 and the fixing device 3. The portal-shaped structure design provides more stable support. The bottom is hollow, providing space for the conveying and movement of the artificial stone blank; there are two cylindrical limiting cylinders 22, which are respectively installed through the center of the top surface of the two first portal-shaped support plates 21; the second portal-shaped support plate 23 is located near the rear end of the top surface of the two first portal-shaped support plates 21, and the second portal-shaped support plate 23 supports the first electric push rod 24 and its connecting parts, and has a certain supporting force and stability; the first electric push rod 24 is located at the left end of the center of the top of the second portal-shaped support plate 23, and the first electric push rod 24 can push the connecting rod 25 to move; the connecting rod 25 is located at the pushing end of the first electric push rod 24, connecting... The connecting rod 25 is used to connect the first electric push rod 24 and the fixed rod 26; the fixed rod 26 is located at the bottom end of the connecting rod 25 and extends towards the rear end of the bottom of the connecting rod 25. The fixed rod 26 is used to support the connecting components of the three-section electric push rod 27; the three-section electric push rod 27 is located at the rear end of the bottom surface of the fixed rod 26; the high-speed spindle motor 28 is located at the pushing end of the three-section electric push rod 27, and the high-speed spindle motor 28 can ensure the cutting stability and accuracy of the saw blade 29; the saw blade 29 is located at the rotating end of the high-speed spindle motor 28; the trigger rod 210 is located at the right end of the front side of the outer wall of the high-speed spindle motor 28. 210 is used to contact the contact sensor 39; the drive assembly is located at the front end of the top face near the first portal support plate 21, and the two moving ends of the drive assembly are respectively sleeved in the two cylindrical limiting cylinders 22; there are two first elastic pressure plates 221, which are respectively located at the two moving ends of the drive assembly. The artificial stone blank may have a small thickness tolerance or a slight unevenness on the surface. The first elastic pressure plate 221 can follow these small dimensional changes through its own deformation; the first pressure sensor 222 is embedded in the center of the bottom surface of one of the first elastic pressure plates 221. The first pressure sensor 222 is used to detect the pressure of fixing the artificial stone blank.

[0035] As a preferred option, further, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the drive assembly includes: rack 211, third portal support plate 212, bearing seat 213, rotating rod 214, gear 215, eccentric cam 216, first connecting rod 217, second connecting rod 218, third connecting rod 219, and pressure rod 220. The rack 211 is located at the top of the front side of the outer wall of the connecting rod 25; the third portal support plate 212 is located at the front end near the top surface of the two first portal support plates 21, and the third portal support plate 212 provides support and load-bearing for the entire drive assembly; there are two bearing seats 213, which are symmetrically arranged at the rear of the top of the outer wall of the third portal support plate 212. The rotating rod 214 is sleeved within two bearing seats 213 on both sides, and can rotate through the two bearing seats 213. A gear 215 is located at the left end of the center of the rotating rod 214, meshing with a rack 211. Two eccentric cams 216 are located at both ends of the rotating rod 214. The eccentricity and variable radius profile of the eccentric cams 216 convert the rotational motion of the gear into an adjustable downward stroke of the three connecting rods. The final position of the connecting rods is passively limited by the thickness of the plate material itself, thus achieving adaptive fixing for plates of any thickness, ensuring reliable fixing while avoiding over-fixation. The compression is the core of the entire drive assembly. When the three links are under force, the force on the plate increases instantaneously, impacting the plate. The smooth transition curve from the proximal to the distal section of the eccentric cam 216 (this part of the profile is the cam's buffer path) plays a crucial role in ensuring a gradual transition in force and displacement when the three links are pushed, avoiding impact caused by abrupt changes in the profile. There are two first links 217, each located at the eccentric end of the two eccentric cams 216. There are two second links 218, each located at one end of the outer wall of the two first links 217 via a first bearing. The connecting rods 218 are rotatable through two first bearings; there are two third connecting rods 219, each set at one end of the outer wall of the two second connecting rods 218 through a second bearing, and the two third connecting rods 219 are rotatable through the two second bearings; there are two pressure rods 220, each set at the bottom end of the two third connecting rods 219, and the two pressure rods 220 are respectively sleeved in the two cylindrical limiting cylinders 22, and the two pressure rods 220 are respectively limited to move up and down within the two cylindrical limiting cylinders 22, and the two pressure rods 220 are respectively connected and fixed to the center of the top surface of the two first elastic pressure plates 221;The first electric push rod 24 pushes the connecting rod 25, which in turn drives the rack 211 to rotate the gear 215. This rotation of the rotating rod 214 causes the two eccentric cams 216 to drive the two pressure rods 220 downwards within the two cylindrical limiting cylinders 22 via the two first connecting rods 217, the two second connecting rods 218, and the two third connecting rods 219. This causes the two pressure rods 220 to move the two first elastic pressure plates 221 downwards. This drive assembly, through its ingenious mechanical linkage design, can adapt to the thickness of the slab and provide a stable and reliable fixing effect, making it ideal for cutting artificial stone slabs of varying thicknesses that require efficient and flexible processing.

[0036] As a preferred option, further, such as Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the fixing device 3 includes: a support plate 31, a second electric push rod 32, a second elastic pressure plate 33, a second pressure sensor 34, a connecting plate 35, a fixing block 36, an elongated cylindrical tube 37, a spring 38, and a contact sensor 39. The support plate 31 is disposed at the front end of the top of a first portal-shaped support plate 21, and the support plate 31 is used to support the entire fixing device 3. The second electric push rod 32 is disposed at one end of the bottom surface of the support plate 31, and the second electric push rod 32 can push the second elastic pressure plate 33 to move. The second elastic pressure plate 33 is located at the pushing end of the second electric push rod 32 and is used to fix the artificial stone blank; the second pressure sensor 34 is embedded in the center of the bottom surface of the second elastic pressure plate 33 and is electrically connected to the first pressure sensor 222; the connecting plate 35 is located at the center of the front side of the outer wall of the support plate 31 and serves to support the fixing block 36; the fixing block 36 is located at the front end of the bottom surface of the connecting plate 35; the elongated cylindrical tube 37 is located at one end of the fixing block 36 and is elongated in shape. The cylinder 37 extends towards the front end of the fixing block 36. Regardless of the thickness of the artificial stone slab being fixed, the trigger rod 210 can contact the contact sensor 39. For artificial stone slabs of different thicknesses, and given that the height of the trigger rod 210 will vary, the contact sensor 39 is designed to be elongated to facilitate contact with the trigger rod 210. The spring 38 is located at one end inside the elongated cylinder 37. The function of the spring 38 is to adapt to the movement requirements of the trigger rod 210 by deforming itself when the trigger rod 210 presses against the contact sensor 39. The contact sensor 39 is located at one end of the spring 38 and is looped around the other end inside the elongated cylinder 37. The contact sensor 39 can move along the inner wall of the elongated cylinder 37. The contact sensor 39 is electrically connected to the second electric push rod 32 and serves as the signal source for the second electric push rod 32. The second pressure sensor 34 is adjusted by using the first pressure sensor 222 as a pressure reference. Furthermore, this device can prevent the end of the artificial stone slab from cracking during sawing, thus improving the sawing quality.

[0037] Through the coordinated operation of the conveying structure 1, the adaptive adjustment device 2, and the fixing device 3, stable conveying, adaptive pressure fixing, and crack-free sawing of artificial stone slabs of different thicknesses are achieved. The specific working principle is as follows:

[0038] The conveying structure 1 is used to accurately transfer the artificial stone blank to the sawing area, providing a basic positioning for subsequent processing. The operating logic of its core components is as follows: The bearing plate 11 serves as the basic support component of the entire device, providing stable support for the top roller conveyor belt 12 and the stone slab support platform 13, ensuring that each component remains in a stable position during operation; after the roller conveyor belt 12 is started, it transports the artificial stone blank to be processed from its initial placement position to the sawing station of the device through the rotation of the rollers, until the part of the blank to be cut is aligned with the gap between the two stone slab support platforms 13 (this gap is reserved for the cutting space of the saw blade 29); after the blank is transported to the position, the two stone slab support platforms 13 jointly support the bottom of the blank, providing a basis for stable force during the sawing process.

[0039] The adaptive adjustment device 2 enables the fitting and sawing of blanks of different thicknesses. Its working process is divided into two stages: adaptive fixing and sawing execution.

[0040] (1) Adaptive fixing stage: The first electric push rod 24 is installed at the top center left end of the second portal support plate 23. After starting, its push end drives the connecting rod 25 to move downward; the rack 211 at the top end of the front side of the outer wall of the connecting rod 25 moves with the connecting rod 25 and meshes with the gear 215 at the center left end of the rotating rod 214, driving the rotating rod 214 to rotate on the third portal support plate 212 through two bearing seats 213; the eccentric cams 216 at both ends of the rotating rod 214 rotate synchronously with the rotating rod 214, and their eccentric ends are connected by the first connecting rod 217 and the second connecting rod 218 (through the first shaft) The sequential transmission of the first elastic pressure plate 221 (connected by the second bearing) and the third connecting rod 219 (connected by the second bearing) pushes the two pressure rods 220 downward within the cylindrical limiting cylinder 22; the first elastic pressure plate 221 connected to the bottom end of the pressure rod 220 moves downward and presses against the surface of the blank, adapting to blanks of different thicknesses through its own elastic deformation: providing sufficient pressure to thick plates to prevent deviation during sawing, and buffering thin plates through deformation to avoid excessive compression and damage; the first pressure sensor 222 embedded in the center of the bottom surface of the first elastic pressure plate 221 detects the current fixed pressure in real time, providing a pressure reference for subsequent end pre-pressing;

[0041] (2) Sawing execution stage: After the blank is self-adaptively fixed, the device enters the sawing execution stage. The specific process is as follows: The fixing rod 26 at the bottom of the connecting rod 25 moves synchronously with the connecting rod 25, driving the three-section electric push rod 27 at the rear end of its bottom surface to approach the blank; the three-section electric push rod 27 starts, and its pushing end drives the high-speed spindle motor 28 to move forward, so that the saw blade 29 at the rotating end of the high-speed spindle motor 28 contacts the part of the blank to be cut; the high-speed spindle motor 28 starts, driving the saw blade 29 to rotate at high speed, and performing transverse sawing on the blank.

[0042] When the saw blade 29 cuts to half the transverse position of the blank, the trigger rod 210 at the right end of the front side of the outer wall of the high-speed spindle motor 28 moves with the saw blade 29 and comes into contact with the contact sensor 39 inside the elongated cylinder 37. The contact sensor 39 adapts to the movement trajectory of the trigger rod 210 through the deformation of the spring 38 and sends a start signal to the second electric push rod 32. The second electric push rod 32, which is installed at one end of the bottom surface of the support plate 31, is activated, and its pushing end drives the second elastic pressure plate 33 to move downward, pre-pressing the top of the cut surface of the remaining uncut blank. The second pressure sensor 34, which is embedded in the center of the bottom surface of the second elastic pressure plate 33, is electrically connected to the first pressure sensor 222. Through feedback adjustment, it ensures that the pre-pressing pressure is consistent with the fixed pressure detected by the first pressure sensor 222, thereby evenly offsetting the stress concentration at the sawing end and preventing the blank from cracking.

[0043] In summary, the conveying structure 1 transports the blank to the top surface of two stone support platforms 13 via the roller conveyor belt 12, aligning the part to be cut with the gap between the two support platforms; the adaptive adjustment device 2 drives mechanical linkage through the first electric push rod 24, causing the first elastic pressure plate 221 to adaptively press and fix the blank, and the first pressure sensor 222 records the current pressure; the three-section electric push rod 27 drives the high-speed spindle motor 28 and saw blade 29 to move forward, and the saw blade 29 rotates at high speed to perform transverse sawing on the blank; when the blank is cut to half, the trigger rod 210 contacts the contact sensor 39, the fixing device 3 is activated, and the second elastic pressure plate 33 pre-presses the end of the blank with the same pressure as the first pressure sensor 222; the saw blade 29 continues to cut to the end, and the blank is sawed without cracking; through the above principle, the device achieves efficient and high-quality sawing of artificial stone slabs of different thicknesses, solving the problems of non-adjustable fixed pressure and easy cracking at the end of traditional devices.

[0044] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
