Description

[0002] When the roll-formed ceramic plate comes out of the press production line, it is a continuous length of slab, which needs to be cut online by cutting equipment into rectangular plates of specified size specifications. As shown in Figure 1, the cutting equipment consists of a conveyor, a transverse cutter, a longitudinal cutter and a control system. Among them, the movement direction of the transverse cutter is set at an angle α with the conveying direction of the slab (X direction); when performing transverse cutting, while the conveyor transports the slab along the X direction, the transverse cutting head of the transverse cutter needs to move along a fixed track for cutting (that is, the transverse cutting head moves along a guide rail that forms an angle α with the conveying direction of the slab (X direction)), and the transverse cutting head needs to meet V1 = V*sinα when cutting, where V1 is the slab movement speed and V is the speed of the cutting head moving along the guide rail, in order to cut into rectangular plates of specified specifications.

[0003] Existing cutting equipment can only cut at a fixed angle at a specified speed. When the moving speed of the slab changes, for example, when the moving speed of the slab is accelerated, that is, Vx>V*sinα, Vx: the moving speed of the slab after acceleration, the cutting equipment cannot complete the cutting of the rectangular plate, that is, the range of processed products is limited by the moving speed of the cutting head and the angle α, and production cannot be flexibly arranged according to product specifications and pressing speed.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims. In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0038] In addition, in this application, unless otherwise specified, "plurality" refers to two or more. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0039] The slabs coming out of the press production line are all continuous in length, so cutting equipment is needed to cut the slabs online into rectangular slabs of specified dimensions. As shown in Figure 1, the movement direction of the transverse cutter is set at an angle α to the slab conveying direction (X direction); during transverse cutting, while the conveyor transports the slab in the X direction, the transverse cutting head of the transverse cutter needs to move along a fixed track to cut (that is, the transverse cutting head moves along a guide rail that forms an angle α with the slab conveying direction (X direction)). Moreover, when cutting, the speed V of the cutting head along the guide rail must satisfy V1 = V*sinα, where V1 is the slab movement speed, in order to cut into rectangular slabs of specified dimensions.

[0040] The above-mentioned cutting equipment can only cut along a fixed angle (i.e. α) at ​​a specified speed. Since the speed of the slabs conveyed out of the press production line will change according to factors such as product specifications, the slab conveying speed of the conveyor also needs to change accordingly; and when the slab moving speed of the conveyor changes, for example, when the slab moving speed is accelerated, that is, Vx>V*sinα, Vx: the moving speed of the slab after acceleration, then the cutting equipment cannot complete the cutting of the rectangular plate, that is, the range of processed products is limited by the moving speed of the cutting head and the angle α, and production cannot be flexibly arranged according to product specifications and pressing speed.

[0041] In combination with Figures 2 and 3, the present application provides an apparatus for online cutting of ceramic plates, which includes: a conveyor 50; a cross-cutter 30, which is arranged on the conveyor 50; the cross-cutter 30 includes a transverse moving mechanism, a longitudinal moving mechanism and a cross-cutting assembly 330; the cross-cutting assembly 330 moves along a cutting track under the joint action of the transverse moving mechanism and the longitudinal moving mechanism, and is used to cut the slab 10 on the conveyor 50 into quadrilateral plates of corresponding specifications.

[0042] Compared with the prior art, the present application synthesizes a cutting trajectory through the joint action of the transverse moving mechanism and the longitudinal moving mechanism, and then moves the cross-cutting component 330 along the cutting trajectory to cut the slab 10 into a rectangular plate 20; the present application abandons the structure and cutting method of the transverse cutting machine in the prior art, and innovatively uses the method of synthesizing the cutting trajectory with the help of two mechanisms, and changes the moving speed of the two mechanisms so as to flexibly arrange production according to product specifications and pressing speeds, and prepare quadrilateral plates of corresponding specifications.

[0043] In a specific embodiment, the equipment for online cutting of ceramic plates of the present application is powered on, the conveyor 50 conveys the slab 10, and the lateral moving mechanism applies a lateral movement trend at a first speed to the cross-cutting component 330, while the longitudinal moving mechanism applies a longitudinal movement trend at a second speed to the cross-cutting component 330 to synthesize different cutting trajectories for cutting the slab on the conveyor into rectangular plates 20 of corresponding specifications.

[0044] Specifically, the lateral movement mechanism and the longitudinal movement mechanism both apply corresponding lateral movement trends and longitudinal movement trends to the cross-cutting assembly 330. By changing the speed of the lateral movement trend (i.e., the first speed) and the speed of the longitudinal movement trend (i.e., the second speed), the cutting trajectories synthesized by the two mechanisms will be different. As shown in Figure 2, since the purpose of this embodiment is to cut the rectangular plate 20, for this purpose, the current cutting trajectories are all oblique cutting trajectories with an angle β relative to the conveying direction of the conveyor 50. By changing the first speed and the second speed, the size of the angle β is changed, thereby having different oblique cutting trajectories. Among them, the first speed is the same as the conveying speed of the conveyor 50, and the direction of the lateral movement trend is the same as the conveying direction of the conveyor 50, so that it can be used in conjunction with the conveying speed of the slab 10 of the press production line; the direction of the longitudinal movement trend is set perpendicular to the conveying direction of the conveyor 50, and the second speed is a preset speed; or the first speed is the same as the conveying speed of the conveyor, and the second speed is related to the conveying speed of the conveyor 50.

[0045] It should be noted that, in addition to being used for online continuous cutting of slabs 10 continuously produced by a continuous roller forming production line for ceramic slabs, the present application can also be used for cutting slabs 10 intermittently produced by a traditional hydraulic brick press, and the present application does not impose any restrictions on this.

[0046] In one embodiment, the conveying speed of the conveyor 50 changes with the conveying speed of the slab 10 of the press production line, so that the conveying speed of the conveyor 50 is synchronized with the conveying speed of the slab 10 of the press production line, so that it can be used in conjunction with the conveying speed of the slab 10 of the press production line; that is, when the conveying speed of the slab 10 of the press production line is 2m / s, the conveying speed of the conveyor 50 is 2m / s; and when the conveying speed of the slab 10 of the press production line is changed to 3m / s, the conveying speed of the conveyor 50 is synchronously changed to 3m / s.

[0047] Alternatively, the conveying speed of the conveyor 50 is determined according to the processing specifications so as to be able to cooperate with the cutting of the slab 10 for intermittent brick production by a traditional hydraulic brick press; that is, the conveying speed of the conveyor is adjusted according to the processing specifications of the rectangular plate to be cut. For example, if a 2.5m*1m rectangular plate needs to be cut, the conveying speed of the conveyor 50 can be set to 2.5m / s.

[0048] In one embodiment, the first speed is the same as the conveying speed of the conveyor, and the second speed is related to the conveying speed of the conveyor.

[0049] Specifically, the second speed V y Satisfies the following formula: Among them, V xis the first speed, l y is the length of the rectangular plate in the y direction (i.e., the direction perpendicular to the conveying direction of the conveyor), l x is the length of the rectangular plate in the x direction (i.e. the conveying direction of the conveyor). In a specific embodiment, when it is necessary to cut a rectangular plate with a specification of 2.5m*1m, i.e. l x =2.5m,l y =1m, the first speed V x =2.5m / s, then V y ≥1m / s.

[0050] Regarding the structures of the transverse movement mechanism and the longitudinal movement mechanism, in one embodiment, the transverse movement mechanism includes a transverse frame 310, the longitudinal direction of which is the same as the conveying direction of the conveyor 50; the longitudinal movement mechanism includes a longitudinal frame 320, which is slidably connected to the transverse frame 310 and moves along the longitudinal direction of the transverse frame 310; and the cross-cutting assembly 330 is slidably connected to the longitudinal frame 320 and moves along the longitudinal direction of the longitudinal frame 320. During the cutting process of the slab 10, as shown in FIG2 , the longitudinal frame 320 moves backward along the longitudinal direction of the transverse frame 310, while the cross-cutting assembly 330 moves leftward along the longitudinal direction of the longitudinal frame 320, thereby cutting the slab 10 along the cutting trajectory.

[0051] It should be noted that the cross-cutting assembly 330 includes a cutting blade and a drive motor for rotating the cutting blade. The drive motor drives the cutting blade to rotate to cut the slab 10. The sliding of the longitudinal frame 320 on the transverse frame 310 and the sliding of the cross-cutting assembly 330 on the longitudinal frame 320 can be achieved using a linear transmission structure, such as a motor-driven synchronous belt, a motor-driven screw, or a motor-driven gear toothed belt. Other conventional technical means known to those skilled in the art can also be used, and this application does not limit this.

[0052] Furthermore, as shown in Figures 2 and 3, there are two transverse frames 310, which are respectively arranged on opposite sides of the conveyor 50; one end of the longitudinal frame 320 is slidably connected to one of the transverse frames 310, and the other end of the longitudinal frame 320 is slidably connected to the other transverse frame 310. In the above manner, the present application arranges transverse frames 310 on opposite sides of the conveyor 50, i.e., on the left and right sides, and makes the left and right ends of the longitudinal frame 320 slidably connected to the left and right sides of the transverse frame 310, respectively, to increase the stability of the longitudinal frame 320 during lateral movement.

[0053] In one embodiment, the cross-cutting component 330 has a starting position and a finishing position relative to the cross-cutting machine 30, and the finishing position is located at the end point of the cutting trajectory; when the cross-cutting component 330 is located at the finishing position, the cross-cutting component 330 returns to the starting position and does not contact the slab 10 of the conveyor 50 during the returning process, waiting for the next cutting.

[0054] Furthermore, the cross-cutting assembly 330 is connected to the longitudinal frame 320 through a lifting mechanism so that the cross-cutting assembly 330 is controlled to move downward to cut the slab 10 during cutting, and is controlled to move upward to not cut the slab 10 when returning to the original position.

[0055] In one embodiment, as shown in Figures 2 and 3, the equipment for online cutting of ceramic plates also includes: a longitudinal cutting machine 40, which is arranged on the conveyor 50, and is used to cut the rectangular plate 20 on the conveyor 50, and cut the rectangular plate 20 longitudinally into two or three pieces or other quantities according to processing specifications, or cut the leftover material on both sides of the rectangular plate 20.

[0056] Furthermore, the slitting machine 40 includes a slitting frame 410 and at least one slitting assembly 420. The slitting frame 410 is disposed across the conveyor 50. The slitting assembly 420 is connected to the slitting frame 410 and is configured to cut the rectangular slabs 20 on the conveyor 50. In this embodiment, the number of slitting assemblies 420 can be adjusted based on the processing specifications. The slitting assemblies 420 are positioned above the rectangular slabs 20 and connected to the slitting frame 410 via a lifting mechanism. This allows the slitting assembly 420 to be controlled to move downward to cut the slab 10 during cutting, and to move upward to not cut the slab 10 when cutting is not required.

[0057] Furthermore, the longitudinal cutting assembly 420 is slidably connected to the longitudinal cutting frame 410 and moves along the length direction of the longitudinal cutting frame 410 so as to adjust the cutting position of the longitudinal cutting assembly 420 .

[0058] It should be noted that, in addition to being able to cut into rectangular plates, the present application can also be cut into parallelogram plates; specifically, as shown in FIG4 , by adjusting the speed of the lateral moving mechanism so that when the first speed is inconsistent with the conveying speed of the conveyor, the cutting shape is a parallelogram; specifically,

[0059] Satisfies the following formula, Among them, V x is the first speed, V y is the second speed, V is the speed of the conveyor, l yis the length of the parallelogram plate in the y direction (i.e., the direction perpendicular to the conveying direction of the conveyor), and L is the offset length of the parallelogram plate relative to the rectangular plate in the x direction (i.e., the conveying direction of the conveyor). After determining the value of L based on the parallelogram to be cut, V can be calculated. x The numerical value of .

Therefore, this application is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this application should also fall within the scope of protection of the claims of this application.
