Description

Technical Field

[0001] The utility model relates to the technical field of artificial stone production equipment, in particular to a crack texture machine. Background Art

[0002] The crack texture of the cracked artificial stone in the prior art is obtained by subjecting the artificial stone mixture to crack processing through a crack texture machine.

[0003] During the crack treatment process, it is necessary to use one or more top-crack expanders in the top-crack mechanism to lift the belt supporting the artificial stone mixture, so that the corresponding position of the bottom of the artificial stone mixture protrudes upward, and cracks are generated at the corresponding parts of the surface of the artificial stone mixture, and then powder of a different color from the mixture is sprayed on the cracks, so as to obtain a crack texture on the surface of the artificial stone.

[0004] The nozzle of the spray gun is easily clogged by agglomerated powder or slurry, so it is often necessary to replace the spray gun and clean the nozzle of the disassembled spray gun.

[0005] The spray gun is prone to tilt or deviation during installation, causing the sprayed powder or slurry to fail to completely cover the corresponding cracks, resulting in unqualified output products that need to be reworked or scrapped. Utility Model Content

[0092] The top cracking mechanism 3 includes a plurality of top cracking expanders 312, which are arranged in a matrix inside the frame 2; the top cracking expanders 312 are used to push up the belt 1 so as to generate cracks on the surface of the artificial stone mixture on the surface of the belt 1;

[0094] The spray gun moving mechanism 7 is mounted above the belt 1; the opening of the nozzle 51 is vertically aligned downward with the transport surface of the belt 1;

[0095] The spray gun moving mechanism 7 drives the spraying mechanism 5 to move forward and backward, left and right, or up and down above the transport surface.

[0096] like Figure 1 and Fig.10 As shown, the crack texture machine of the utility model sprays powder or slurry on the cracks through a spray gun 51 to form crack textures on the cracks, and limits the top surface of the spray gun 51 through a limiting device so that the opening of the nozzle 512 is vertically aligned downward with the transport surface of the belt 1 to avoid the spray gun from being skewed or offset during installation, thereby avoiding the output product being unqualified due to the sprayed powder or slurry failing to completely cover the corresponding cracks, reducing rework or scrapping, and thereby improving the qualified rate of products.

[0097] Specifically, the driving mechanism 6 includes a reduction motor 60, an active roller 61, a passive roller 62, two driven rollers 63, two auxiliary rollers 64, a plurality of roller shaft fixing seats 66 and a plurality of drivers 65;

[0098] The driver 65 is mounted on each of the four corners of the frame 2; the roller shaft fixing seats 66 are mounted on both the left and right ends of the driven roller 63;

[0099] The output end of the driver 65 is connected to the front end surface of the roller fixing seat 66 close to the front end of the frame 2, or the output end of the driver 65 is connected to the rear end surface of the roller fixing seat 66 close to the rear end of the frame 2; the output end of the driver 65 drives the corresponding roller fixing seat 66 to move forward or backward a set distance through the corresponding roller fixing seat 66 to loosen or tighten the belt 1.

[0100] like Figure 1-3 and Figure 6-7As shown in the figure, the passive roller 62 and the active roller 61 are respectively mounted near the top surface of the front and rear ends of the frame 2, and the output end of the reduction motor 60 is connected to the left or right end of the active roller 61; the two auxiliary rollers 64 are respectively mounted near the bottom of the front and rear ends of the frame 2; the two driven rollers 63 are respectively mounted near the middle of the front and rear ends of the frame 2; along the up and down direction, the driven roller 63 is located between the passive roller 62 or the active roller 61 and the auxiliary roller 64; one end of the belt 1 passes around the top surface of the outer circumference of the active roller 61, and then passes around the main roller 61 in sequence.

[0101] like Figure 1 , Figure 6 and Figure 7 As shown, when it is necessary to use the top splitting expansion device of the top splitting mechanism 3 to lift the artificial stone mixture upward, the four drivers 65 located at the four corners will synchronously retract the corresponding output ends, so that the two roller fixing seats 66 close to the front end of the frame 2 will synchronously move forward a set distance, and the two roller fixing seats 66 close to the rear end of the frame 2 will synchronously move backward a set distance, so that the belt 1 is relaxed, and then the corresponding parts of the belt 1 are lifted upward by some of the top splitting expansion devices in the top splitting mechanism 3, so that cracks are generated in the corresponding parts of the surface of the artificial stone mixture located on the top surface of the belt 1, and then the powder or slurry of a different color from the mixture is sprayed at each crack by the spraying mechanism 5 to form a crack track to complete the corresponding crack texture processing.

[0102] After the above crack texture processing is completed, the raised top crack expander descends and resets, and the corresponding output ends of the four drivers 65 located at the four corners of the frame 2 are synchronously extended, so that the two roller fixing seats 66 close to the front end of the frame 2 are synchronously moved backward by a set distance, and the two roller fixing seats 66 close to the rear end of the frame 2 are synchronously moved forward by a set distance, so that the belt 1 is tensioned and reset, thus completing a cycle of relaxation and tensioning of the belt 1.

[0109] The bearing fixing sleeve 662 is a hollow ring, and the bearing fixing sleeve 662 is embedded and fixed in the middle of the sliding seat 661; the inner wall surface of the bearing fixing sleeve 662 is connected to the outer peripheral surface of the rotating shaft sleeved on the left end or the right end of the driven roller 63;

[0110] The connecting portion 6613 is an end portion of the sliding seat 661 away from the center of the frame 2, and a mounting hole is provided in the middle of the connecting portion 6613; the output end of the driver 65 passes through the mounting hole and is fixed to one end of the sliding seat 661 by a fastener.

[0111] like Fig. 9 As shown, the driver 65 drives the sliding seat 661 and the driven roller 63 to move along the guide rail 663 close to the front end face or the rear end face of the frame 2 by pulling the connecting portion 6613, so as to relax the belt 1; the driver 65 drives the sliding seat 661 and the driven roller 63 to move away from the front end face or the rear end face of the frame 2 along the guide rail 663 by pushing the connecting portion 6613, so as to reset the driven roller 63 and tighten the belt 1 again.

[0112] Furthermore, it also includes a PLC control unit; the driving mechanism 6 also includes a positioning component 67;

[0116] The distance between the first sensor 672 and the second sensor 673 is the set distance; the trigger end of the first sensor 672 and the trigger end of the second sensor 673 are respectively located at the top of the first sensor 672 and the second sensor 673; the first sensor 672, the second sensor 673 and the driver 65 are respectively connected to the PLC control unit signal.

[0117] like Figure 8 As shown, when the belt 1 needs to be relaxed, the four drivers 65 are started synchronously and retract the corresponding output ends, and drive the two driven rollers 63 to approach the front end face and the rear end face of the frame 2 respectively, and synchronously drive the positioning rod 671 to leave the top of the corresponding first sensor 672, and the positioning rod 671 continues to move following the left end or the right end of the corresponding driven roller 63. When the positioning rod 671 reaches the top of the corresponding second sensor 673, the corresponding second sensor 673 is triggered and sends a signal to the corresponding driver 65 through the PLC control unit. The corresponding driver 65 stops retracting the corresponding output end after receiving the signal. At this time, the distance moved by the driven roller 63 to the front end face or the rear end face of the frame 2 is the set spacing, so that the belt 1 reaches the set relaxation requirement.

[0118] On the contrary, when it is necessary to tension the belt 1, the four drivers 65 are started synchronously and the corresponding output ends are extended, driving the two driven rollers 63 to leave the front end and rear end faces of the adjacent frame 2 respectively and move toward the middle of the frame 2, and synchronously driving the positioning rod 671 to leave the top of the corresponding second sensor 672, and the positioning rod 671 continues to move following the left end or right end of the corresponding driven roller 63. When the positioning rod 671 reaches the top of the corresponding first sensor 673, the corresponding first sensor 673 is triggered and sends a signal to the corresponding driver 65 through the PLC control unit. The corresponding driver 65 stops extending the corresponding output end after receiving the signal. At this time, the distance moved by the driven roller 63 to the middle of the frame 2 is the set spacing, so that the two driven rollers 63 are reset and the belt 1 is tensioned again.

[0119] Furthermore, the driving mechanism 6 also includes a limit block 68 and a limit plate 69;

[0120] The front end face or the rear end face of the limit block 68 is used to abut against the side surface of the roller fixing seat 66 away from the connecting portion 6613, and the corresponding rear end face or the front end face of the limit block 68 is fixed to the frame 2;

[0124] like Figure 8 As shown, when the belt 1 is tightened, the limit block 68 can limit the maximum stroke of the driven roller 63 approaching the middle of the frame 2 to prevent the driven roller 63 from being displaced when resetting. Conversely, when the belt 1 is loosened, the limit plate 69 can limit the maximum stroke of the driven roller 63 approaching the front and rear ends of the frame 2 to prevent the driven roller 63 from being displaced when the belt 1 is loosened.

[0125] Artificial stone mixtures of different thicknesses or weights require different jacking heights, so the distance between the first sensor 672 and the second sensor 673 needs to be adjusted accordingly.

[0126] By using the horizontal mounting groove 6741, the operational convenience of adjusting the distance between the first sensor 672 and the second sensor 673 can be improved; when the first sensor 672 and / or the second sensor 673 is misaligned, the misalignment of the first sensor 672 and / or the second sensor 673 can be corrected by adjusting the relative position of the first sensor 672 and / or the second sensor 673 in the horizontal mounting groove 6741, which is convenient for operation.

[0127] Furthermore, the four corners of the frame 2 are provided with mounting frames 24;

[0128] The installation frame 24 includes a first vertical frame plate 241 and a second vertical frame plate 242;

[0132] A driver mounting hole 2411 is provided in the middle of the exposed vertical surface of the first vertical frame plate 241;

[0133] The driver installation hole 2411 penetrates the first vertical frame plate 241 from front to back; the output end of the driver 65 passes through the driver installation hole 2411 and the middle of the connecting portion 6613 in sequence, and is fixed to one end of the sliding seat 661 by a fastener;

[0138] By shielding the first vertical frame plate 241 and the second vertical frame plate 242, the front and rear surfaces of the left or right end of the passive roller 62, the driven roller 63 and the auxiliary roller 64, as well as the front and rear surfaces of the roller fixing seat 66, the positioning assembly 67, the limit block 68 and the limit plate 69 can be prevented from being collided during operation, thereby improving the operating safety and stability of the corresponding components.

[0139] It should be noted that the exposed vertical surface of the first vertical frame plate 241 refers to the plate surface of the first vertical frame plate 241 exposed at the front end surface or the rear end surface of the frame 2 .

[0140] The central axis of the driver mounting hole 2411 and the central axis of the connecting part 661 are located on the same horizontal straight line, which can improve the operating stability of the output end of the driver 65 and the consistency of the synchronous moving distance of the left and right ends of the same driven roller 63, and avoid skewing or displacement of one of the left and right ends of the same driven roller 63.

[0141] When installing the driver 65, the output end of the driver 65 can be supported by hand through the installation operation hole 691, which can improve the operational convenience of installing the output end of the driver 65. The installation operation hole 691 can also be used to detect whether the central axis of the output end of the driver 65 is in a horizontal state to ensure the installation quality of the driver 65.
