Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a quartz stone plate trimming machine. Background Art

[0002] Quartz stone slabs have become a popular decorative material due to their high hardness and nearly seamless splicing. Its main material is quartz sand, and the rich combination of colors gives it the texture of natural stone and a beautiful surface gloss.

[0003] In order to facilitate use, quartz stone slabs often need to be trimmed and beautified. Under existing conditions, a quartz stone slab trimming machine such as the one disclosed in CN210791546U is used, which can position the quartz stone slabs and facilitate cutting of quartz stone slabs of different sizes. However, the quartz stone slabs have certain sizes, so it is necessary to frequently adjust the position of the slabs or the cutter, or even perform a relatively large-scale flipping operation. The prior art also requires frequent loosening and tightening operations during the adjustment of the quartz stone slabs, which not only affects the trimming efficiency, but also makes it more likely to cause the quartz stone to slip and fall off.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 A quartz stone slab trimming machine comprises a processing machine table 1, and two ends of the processing machine table 1 are fixedly connected with left-right symmetrically distributed load-bearing brackets 2, and the upper end of the load-bearing bracket 2 is provided with a first motor 4 and a first clamping piece 6 driven to rotate by the first motor 4 and used to fit one end of the quartz stone slab.

[0023] The load-bearing bracket 2 is provided with a limiting mechanism for fixing the other end of the quartz stone plate through the ball screw 7. Figure 2 With attached Figure 3 :

[0024] On the one hand, the limiting mechanism includes a moving nut 8 that is配套设置于滚珠丝杆7上 (matched and arranged on the ball screw 7), and a guide rod 9 that is fixedly installed on the moving nut 8 and slides through the load-bearing bracket 2. A moving bracket 10 is fixedly installed on the guide rod 9, and a driven shaft 11 is rotatably installed in the moving bracket 10. A second clamping member 12 is fixedly installed on the driven shaft 11. Under the traction of the moving nut 8, the plate can be horizontally moved, that is, the plate is preliminarily sleeved and limited by the first clamping member 6 and the second clamping member 12. A U-shaped cavity 13 and a limiting notch 14 that are connected are formed in the second clamping member 12. A rotating shaft 15 is rotatably installed in the U-shaped cavity 13. A driving gear 16 is key-connected to the rotating shaft 15. Two driven racks 17 that are meshed with the driving gear 16 are slidably sleeved in the U-shaped cavity 13. A clamping plate 18 that is movably pulled by the driven rack 17 and is used for clamping the quartz stone plate is rotatably installed in the limiting notch 14. By controlling the opening and closing movement of the clamping plate 18 in the second clamping member 12, the end of the quartz stone plate located in the second clamping member 12 is clamped and limited.

[0025] On the other hand, a turntable 20 is fixedly installed on the driven shaft 11, and a plurality of limiting holes 21 are formed in the turntable 20. A limiting bolt 22 corresponding to the limiting holes 21 is slidably sleeved in the second clamping member 12. A strong spring 23 that is welded to the second clamping member 12 is fixedly sleeved on the limiting bolt 22. Under the tension of the strong spring 23, the limiting bolt 22 can extend into the limiting hole 21 therein to fix the angles of the turntable 20 and the rotating shaft 15 rotated to a predetermined angle.

[0026] A load-bearing truss 3 that is symmetrically distributed front and back is fixedly arranged between the two load-bearing brackets 2. A driver 24 and a cutter 25 that is controlled by the driver 24 to open and close are arranged in the load-bearing bracket 2. The cutter 25 is controlled by the driver 24 to contact the quartz stone plate and perform edge cutting on the quartz stone plate.

[0027] Based on this, it can be further extended:

The ball screw 7 is rotatably installed between the two load-bearing brackets 2. The rotating ball screw 7 drives the second clamping member 12 to move horizontally through the moving nut 8.

[0029] The second clamping member 12 is horizontally corresponding to the first clamping member 6, and the two driven racks 17 are symmetrically arranged on both sides of the driving gear 16.

[0030] A traction connecting rod 19 is pin-connected between the driven rack 17 and the clamping plate 18.

[0031] The limiting holes 21 are equidistantly distributed in the circumferential direction, so that the limiting plugs 22 can fix the angle of the turntable 20 rotated to any angle.

[0032] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0033] The functional principle of the utility model can be explained through the following operation modes:

[0034] Put the two ends of the plate into the first clamping member 6 and the second clamping member 12 respectively, and control the second motor 5 to start;

[0035] The second motor 5 drives the ball screw 7 to rotate, and the moving nut 8 drives the driven shaft 11 to move horizontally through the guide rod 9 and the moving bracket 10, so that the second clamping member 12 moves toward the first clamping member 6, and the end of the plate contracts into the first clamping member 6;

[0036] The limiting plug 22 is pulled out from the limiting hole 21 to release the limiting of the rotating shaft 15, and the rotating shaft 15 and the driving gear 16 are controlled to rotate, driving the two driven racks 17 to move in the opposite direction. The driven racks 17 support the clamping plate 18 to open through the traction connecting rod 19, so as to clamp and fix one end of the plate in the second clamping member 12;

[0037] Controlling the first motor 4 to start, so as to drive the plate to flip;
