Description

Technical Field

[0001] The utility model relates to the technical field of jade processing, in particular to a long-line wire cutting machine. Background Art

[0002] Jade cutting is a very important step in jade processing. The shape and form of the jade are designed and cut according to the jade material, so that the jade craftsmen can use it rationally. Small pieces of jade are further cut into the required size using saw blades.

[0003] Specifically, application number CN202011424290.4 discloses a cutting device, and more particularly relates to a long jade cutting device. A long jade cutting device is provided that does not require manual fixing of jade by staff, has high jade cutting efficiency, and high cutting accuracy. The present invention provides such a long jade cutting device, comprising a base, a discharging mechanism, and a cutting mechanism; a discharging mechanism is provided on the top of the base, and a cutting mechanism is provided on the left side of the top of the base. Through the cooperation between the limit block and the card plate, after the jade strip is cut by the second cutting blade, the card plate clamps the limit block so that the jade strip is fixed during the process of rotating from the second cutting blade to the first cutting blade, making it convenient for the first cutting blade to continue cutting the jade strip, thereby improving cutting efficiency; through the cooperation between the storage basket and the screening plate, the cut jade blocks fall onto the screening plate in the storage basket. Since the volume of the jade blocks is larger than the sieve holes of the screening plate, the jade blocks remain on the screening plate.

[0004] Another example is application number CN202221801699.8, which discloses a jade cutting machine comprising a cutting platform, a cutting mechanism disposed on the cutting platform, a cutting saw blade driven to rotate thereby being mounted on the cutting mechanism, a clamping device being provided on the top of the cutting platform, the clamping device being slidably connected to the top of the cutting platform along the cutting direction of the cutting saw blade; an auxiliary push handle for assisting staff in pushing the clamping device is provided on the pushing slide. After the jade workpiece is clamped on the clamping device, the staff can push the clamping device to move along the cutting direction of the cutting saw blade, so that the jade workpiece is close to the cutting saw blade for cutting, thereby effectively avoiding the disadvantage of manually fixing the jade workpiece, effectively improving the safety of jade cutting, and reducing the possibility of staff being cut by the cutting saw blade.

[0005] However, during the jade cutting process, due to the thickness of the saw blade itself, the surface of the manually cut small pieces of jade is uneven, resulting in a large number of defects after processing and excessive loss of jade.

[0006] Therefore, during the jade cutting process, abrasive wires are used for sawing. The friction between the guide wheel and the abrasive wire drives the wire in a single direction, achieving the desired effect. However, throughout the sawing process, the guide wheel suffers from constant friction, leading to severe wear. This necessitates regular replacement to ensure proper operation, reducing overall processing efficiency and increasing maintenance costs. Utility Model Content

[0007] Based on this, in order to solve the problem that the guide wheel of the traditional jade wire cutting machine is severely worn and needs to be replaced regularly, resulting in low work efficiency and high maintenance cost, the utility model provides a long-line wire cutting machine, and its specific technical solution is as follows:

[0008] A long-line wire cutting machine comprises a frame, a cutting line and a feeding device, wherein the feeding device controls the workpiece to abut against and away from the cutting line, and the feeding device is mounted on the frame; and further comprises:

[0010] a base, the base being slidably connected to the frame;

[0011] A thread rolling drum, wherein the cutting wire is wound around the thread rolling drum and the guide wheel assembly, and both ends of the cutting wire are fixed to the outer surface of the thread rolling drum;

[0012] a first driving device, the first driving device winding the cutting wire by controlling the wire rolling drum to rotate forward and reverse, the first driving device being mounted on the base;

[0013] A feeding assembly is installed on the base and connected to the output end of the first driving device. The feeding assembly controls the base to feed along the axial direction of the thread rolling cylinder through the first driving device.

[0014] The above-mentioned long-line wire cutting machine is provided with a guide wheel group and a wire rolling drum, and the cooperation between the guide wheel group and the wire rolling drum is used to realize that the cutting wire is wound around the guide wheel group and the wire rolling drum; further, the first driving device winds the cutting wire by controlling the forward and reverse rotation of the wire rolling drum. Compared with the traditional wire cutting machine that drives the sanding wire to move in one direction by the friction generated between the guide wheel and the sanding wire to achieve the cutting of the workpiece, the wire rolling drum of the utility model can wind the long-line cutting wire and control the forward and reverse rotation of the wire rolling drum by the first driving device to realize the reciprocating motion of the cutting wire, thereby avoiding the wear of the guide wheel group, thereby greatly extending the service life of the guide wheel group and reducing the replacement The number of times the guide wheel group is rotated reduces downtime and improves cutting efficiency. In particular, the cutting wire is wound around the wire rolling drum and the guide wheel group, and both ends of the cutting wire are fixed to the outer surface of the wire rolling drum, so that the long-line cutting wire can be wound around the wire rolling drum. Compared with the single-line and single-direction operation of the transmission wire cutting machine, the way the wire rolling drum is wound around the cutting wire is combined with the forward and reverse rotation of the wire rolling drum, so that the guide wheel is not easy to wear. At the same time, the first drive device drives the wire rolling drum to rotate while also controlling the feed movement of the base along the axis of the wire rolling drum, and then controls the feed movement of the wire rolling drum, thereby avoiding overlapping of the cutting wire wound on the wire rolling drum. This long-line wire cutting machine has the advantages of simple and compact structure, low failure rate, wear-resistant wearing parts and high cutting efficiency.

[0016] Furthermore, the base is provided with a bearing seat, and the transmission shaft is inserted into the bearing seat.

[0017] Furthermore, the axis of the transmission shaft and the axis of the thread rolling cylinder are coaxially arranged.

[0018] Furthermore, the feed assembly includes a screw, a second pulley and a second transmission belt; the second pulley is sleeved on the screw and rotates synchronously with the screw, and the screw is threadedly connected to the frame; the transmission shaft is connected to the second pulley through the second transmission belt.

[0019] Furthermore, the axis of the screw rod is parallel to the axis of the transmission shaft.

[0020] Furthermore, the long-line wire cutting machine also includes a first slide rail and a first slider slidably connected to the first slide rail. The length direction of the first slide rail extends along the axial direction of the wire rolling drum and is installed on the frame. The first slider is installed on the base.

[0036] The "first", "second" in the present application do not represent the specific number and order, but only for the name of the distinction.

[0037] As Figures 1-6As shown, a long-line wire cutting machine in one embodiment of the utility model includes a frame 1, a cutting wire 2 and a feeding device 3, the feeding device 3 controls the workpiece 35 to abut and move away from the cutting wire 2, and the feeding device 3 is installed on the frame 1; it also includes a guide wheel group 4, a base 5, a thread rolling drum 6, a first drive device 7 and a feeding assembly 8; the guide wheel group 4 is installed on the frame 1; the base 5 is slidably connected to the frame 1; the cutting wire 2 is wound around the thread rolling drum 6 and the guide wheel group 4, and both ends of the cutting wire 2 are fixed to the outer surface of the thread rolling drum 6; the first drive device 7 controls the thread rolling drum 6 to rotate forward and reverse to wind the cutting wire 2, and the first drive device 7 is installed on the base 5; the feeding assembly 8 is installed on the base 5 and is connected to the output end of the first drive device 7, and the feeding assembly 8 controls the base 5 to feed along the axial direction of the thread rolling drum 6 through the first drive device 7.

[0038] The above-mentioned long-line wire cutting machine is provided with a guide wheel group 4 and a wire rolling drum 6, and the cooperation between the guide wheel group 4 and the wire rolling drum 6 is used to realize that the cutting wire 2 is wound around the guide wheel group 4 and the wire rolling drum 6; further, the first driving device 7 winds the cutting wire 2 by controlling the forward and reverse rotation of the wire rolling drum 6. Compared with the traditional wire cutting machine that drives the sanding wire to move in one direction by the friction force generated between the guide wheel and the sanding wire to achieve the cutting of the workpiece, the wire rolling drum 6 of the utility model can wind the long-line cutting wire 2, and control the forward and reverse rotation of the wire rolling drum 6 through the first driving device 7 to realize the reciprocating motion of the cutting wire 2, avoiding the wear of the guide wheel group 4, thereby greatly extending the service life of the guide wheel group 4 and reducing the replacement of the guide wheel group 4. The number of times the wheel group 4 is rotated reduces downtime and improves cutting efficiency. In particular, the cutting wire 2 is wound around the thread rolling drum 6 and the guide wheel group 4, and both ends of the cutting wire 2 are fixed to the outer surface of the thread rolling drum 6, so that the long-line cutting wire 2 can be wound around the thread rolling drum 6. Compared with the single-line and single-direction operation of the transmission wire cutting machine, the way the thread rolling drum 6 winds the cutting wire 2 is combined with the forward and reverse rotation of the thread rolling drum 6, so that the guide wheel 96 is not easy to wear. At the same time, the first driving device 7 drives the thread rolling drum 6 to rotate while also controlling the feed movement of the base 5 along the axial direction of the thread rolling drum 6, and then controls the feed movement of the thread rolling drum 6, so as to avoid overlapping of the cutting wire 2 when wound on the thread rolling drum 6. The long-line wire cutting machine has the advantages of simple and compact structure, low failure rate, wear-resistant wearing parts and high cutting efficiency.

[0039] This long-line wire cutting machine is used for cutting jade, jade articles or other materials.

[0040] Preferably, the cutting line 2 is a sand line.

[0041] like Figure 2 and Figure 5As shown, in one of the embodiments, the first driving device 7 comprises a transmission shaft 71, a rotary motor 72, a first pulley 73 and a first transmission belt 74; the transmission shaft 71 is arranged on the base 5 and can rotate relative to the base 5; the first pulley 73 is sleeved on the transmission shaft 71, and one end of the transmission shaft 71 is inserted into the rolling thread cylinder 6; the output end of the rotary motor 72 is in transmission connection with the first pulley 73 through the first transmission belt 74, and the rotary motor 72 is arranged on the base 5.

[0042] Further, as shown, Figure 3 The rack 1 is provided with a first proximity switch 54 and a second proximity switch 55, and the rotary motor 72 is in communication connection with the first proximity switch 54 and the second proximity switch 55. That is, the positions of the base 5 or the rolling thread cylinder 6 are monitored by using the first proximity switch 54 and the second proximity switch 55, so as to control the rotary motor 72 to rotate forward and reverse. That is, when the rolling thread cylinder 6 rotates to cut the wire 2 to be continuously wound and moves forward along the axis direction of the rolling thread cylinder 6, the first proximity switch 54 monitors that the base 5 or the rolling thread cylinder 6 reaches a predetermined position, and then the first proximity switch 54 controls the rotary motor 72 to slow down and stop, and then the rotary motor 72 rotates in the opposite direction and moves backward along the axis direction of the rolling thread cylinder 6. When the second proximity switch 55 monitors that the rolling thread cylinder 6 or the base 5 moves to a predetermined position, the second proximity switch 55 controls the rotary motor 72 to slow down and stop, and then rotates in the opposite direction and moves, and the above-mentioned actions are repeated.

[0043] In one of the embodiments, the base 5 is provided with a bearing seat 51, and the transmission shaft 71 is inserted into the bearing seat 51.

[0044] Preferably, the number of the bearing seats 51 is two, and the two bearing seats 51 are arranged at intervals, and the transmission shaft 71 is inserted into the bearing seat 51.

One end of the second transmission belt 83 is sleeved on the third pulley 84, and the other end of the second transmission belt 83 is sleeved on the second pulley 82. In this way, the transmission efficiency and stability between the transmission shaft 71, the second pulley 82, the third pulley 84, the lead screw 81 and the second transmission belt 83 are ensured.

[0049] Preferably, as Figure 2 With Figure 5 As shown, the diameter of the second pulley 82 is greater than that of the third pulley 84. In this way, when the rotary motor 72 controls the transmission shaft 71 and the rolling wire barrel 6 to rotate one revolution through the first transmission belt 74 and the first pulley 73, at the same time, the third pulley 84 and the second transmission belt 83 control the second pulley 82 to rotate, the second pulley 82 rotates and drives the lead screw 81 to rotate, thereby controlling the base 5 to move forward or backward along the axis of the rolling wire barrel 6 by 0.5MM. The rolling wire barrel 6 is realized to rotate while moving, so that overlapping is avoided when the cutting wire 2 on the rolling wire barrel 6 is wound.

[0050] In one embodiment, the axis of the lead screw 81 is parallel to the axis of the transmission shaft 71.

[0051] In one embodiment, the long-line wire cutting machine further comprises a first sliding rail 52 and a first sliding block 53 in sliding connection with the first sliding rail 52. The length direction of the first sliding rail 52 extends along the axis direction of the rolling wire barrel 6 and is arranged on the rack 1, and the first sliding block 53 is arranged on the base 5. In this way, the smoothness of the movement of the base 5 is ensured, and the hard friction with the rack 1 is reduced.

[0053] In one embodiment, the first proximity switch 54 and the second proximity switch 55 are arranged on the side of the first sliding rail 52 and are arranged in the length direction of the first sliding rail 52. The first proximity switch 54 and the second proximity switch 55 are used to monitor the position of the base 5, and when the base 5 reaches a predetermined position, the first proximity switch 54 and the second proximity switch 55 send an electrical signal to the rotary motor 72. In this way, by monitoring the position of the base 5, the forward rotation and reverse rotation of the rotary motor 72 are controlled.

In this way, by using the gravity of the counterweight 91, a transverse pulling force is applied to the second sliding block 93, i.e. a pulling force is applied to any one of the guide wheels of the guide wheel set 4, so as to ensure the tension of the cutting wire 2, thereby ensuring the cutting quality.

[0055] In one embodiment, the tensioning assembly 9 further comprises a second sliding rail 94 and a third sliding rail 95; the second sliding rail 94 is arranged in a vertical direction on the frame 1, and the counterweight 91 is in sliding connection with the second sliding rail 94; the third sliding rail 95 is arranged in a transverse direction on the frame 1, and the second sliding block 93 is in sliding connection with the third sliding rail 95.

[0056] In one embodiment, the guide wheel set 4 is composed of a first guide wheel 41, a second guide wheel 42, a third guide wheel 43 and a fourth guide wheel 44; the first guide wheel 41 and the second guide wheel 42 are arranged side by side and spaced apart, and the third guide wheel 43 and the fourth guide wheel 44 are arranged side by side and spaced apart; the first guide wheel 41 is located above the third guide wheel 43, and the second guide wheel 42 is located above the fourth guide wheel 44; the wire rolling cylinder 6 is located between the first guide wheel 41 and the second guide wheel 42, and the wire rolling cylinder 6 is located above the first guide wheel 41 and the second guide wheel 42; the cutting wire 2 is wound around the wire rolling cylinder 6, the first guide wheel 41, the second guide wheel 42, the third guide wheel 43 and the fourth guide wheel 44.

[0057] Preferably, the second sliding block 93 is fixedly connected with the first guide wheel 41; and the extension line of the third sliding rail 95 intersects with the extension line of the first sliding rail 52.

[0058] That is, the counterweight 91 controls the distance between the first guide wheel 41 and the second guide wheel 42 by using the gravity, and the greater the distance, the greater the tension.

[0059] In one embodiment, the tensioning assembly 9 further comprises a guide wheel 96, and the traction wire 92 is in contact with the guide wheel 96. In this way, it is ensured that the traction wire 92 does not interfere with the frame 1, and it is ensured that the second sliding block 93 moves transversely along the third sliding rail 95.
