Description

Technical Field

[0001] This invention relates to the field of steel wire mesh production technology, specifically to a diamond blade and cutting equipment for improving the cutting quality of steel wire mesh. Background Technology

[0002] Steel wire mesh pipes, with their excellent wear resistance and corrosion resistance, are gradually being used and promoted in fields such as tailings and slurry transportation. Currently, most of the matching wear-resistant steel wire mesh pipe fittings are steel-lined wear-resistant pipe fittings, and the connection method is flange connection.

[0003] Steel wire mesh pipe has higher pressure resistance. At the same time, this composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas transmission pipeline systems. The pipe fittings used in steel wire mesh pipe are polyethylene electrofusion fittings. During connection, the heating element inside the fitting melts the outer plastic layer of the pipe and the inner plastic layer of the fitting, reliably connecting the pipe and fitting together.

[0004] Existing wire mesh pipes generally require cutting during use. However, existing cutting equipment requires the cutting disc to be activated to cut the wire mesh pipe after it has been transported a certain distance, which complicates the operation and reduces cutting efficiency.

[0013] A transmission control mechanism is disposed on the horizontal plate and connected to the bidirectional rotation component and the drive component. The horizontal plate is also provided with a trigger component connected to the transmission control mechanism and the drive component. The trigger component can be activated when the drive component moves and control the bidirectional rotation component to move through the transmission control mechanism, so as to drive the second rotating rod to rotate.

[0016] As a further embodiment of the present invention: the driving assembly includes a rotating sleeve rotatably mounted on one end of the horizontal plate facing the base and symmetrically arranged, a pulley fixed to one end of the rotating sleeve away from the horizontal plate, a conveyor belt sleeved on the pulley, a first support rod fixed on the conveyor belt, the first support rod cooperating with the groove, and the rotating sleeve connected to the transmission control mechanism and the triggering assembly.

[0018] As a further embodiment of the present invention: the transmission control mechanism includes a slot formed on the side wall of the rotating sleeve, a limiting ring that cooperates with the slot is movably installed inside the rotating sleeve, a spring that abuts against the limiting ring is sleeved on the rotating sleeve, a locking assembly that connects to the limiting ring and the first belt is provided on the horizontal plate, and the limiting ring is connected to the triggering assembly.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: The present application can perform equidistant cutting of wire mesh tubes. When it is necessary to cut the wire mesh tube, under the action of the drive component, the cutting disc is controlled to reciprocate in the horizontal direction by the guide mechanism. When the drive component and the trigger component cooperate, the transmission control mechanism is driven to move, so that the bidirectional rotating component moves, thereby driving the conveying roller to rotate through the second rotating rod. Under the action of the conveying roller, the wire mesh tube is conveyed. When the drive component and the trigger component are separated, the transmission control mechanism no longer controls the bidirectional rotating component to move. At this time, the drive component can drive the cutting disc to cut the wire mesh tube through the guide mechanism. Repeat the above steps to perform equidistant cutting of the wire mesh tube.

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.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0035] Please see Figures 1-9 In this embodiment of the invention, a cutting device includes:

[0036] A base 1, on which symmetrically arranged fixing plates 2 are fixedly installed, and a horizontal plate 5 is fixed between the fixing plates 2;

[0037] Baffle 3, fixedly installed on the base 1, with symmetrically arranged support rollers 4 rotatably mounted on the baffle 3;

[0038] When it is necessary to cut the wire mesh tube, the wire mesh tube can be placed on the support roller 4. The support roller 4 is symmetrically inclined to ensure support for the wire mesh tube.

[0039] Please see Figures 1-3 , Figure 5 , Figure 6 A guiding mechanism is provided on the fixed plate 2. A blade is connected to the guiding mechanism. The guiding mechanism includes a guide rod 6 fixedly installed on the fixed plate 2. A guide sleeve 7 is movably installed on the guide rod 6. A movable plate 8 is fixed to the side wall of the guide sleeve 7. A limiting component connected to the guide sleeve 7 and the guide rod 6 is provided on the fixed plate 2. The movable plate 8 is connected to the blade. The limiting component is connected to the driving component. The limiting component includes a limiting groove formed in the inner wall of the guide sleeve 7. A limiting rod that engages with the limiting groove is fixed to the side wall of the guide rod 6. A receiving plate 10 is fixed on the side of the guide sleeve 7 away from the movable plate 8. A groove connected to the driving component is formed on the receiving plate 10.

[0040] In detail, this application controls the reciprocating motion of the cutting disc 9 in the horizontal direction to cut intermittently conveying pipes. Initially, the cutting disc 9 is at the end of its stroke towards one of the fixed plates 2. When cutting the wire mesh pipe is required, the receiving plate 10 with a groove is controlled to move under the action of the drive assembly, thereby driving the guide sleeve 7 to move. Because the limiting groove and the limiting rod are engaged, the guide sleeve 7 moves along the length of the guide rod 6 without deflection. The guide sleeve 7 also drives... The movable plate 8 moves, thereby driving the cutting disc 9 to move towards the wire mesh tube. The movable plate 8 is also equipped with a motor to drive the cutting disc 9 to rotate. When the cutting disc 9 moves to the position of contact with the wire mesh tube, it cuts the wire mesh tube under the action of the cutting disc 9. After the cutting is completed, the guide sleeve 7 moves to the end of its stroke towards the other fixed plate 2. At this time, the wire mesh tube can be controlled to travel a certain distance, and under the action of the drive component, the cutting disc 9 is controlled to move towards the initial position to perform intermittent cutting of the wire mesh tube.

[0041] Please see Figures 1-5 , Figures 7-9 The horizontal plate 5 is provided with a drive assembly connected to the guide mechanism. The drive assembly can drive the blade to reciprocate in the horizontal direction through the guide mechanism. The drive assembly includes a rotating sleeve 11 rotatably mounted on one end of the horizontal plate 5 facing the base 1 and arranged symmetrically. A pulley 12 is fixed to one end of the rotating sleeve 11 away from the horizontal plate 5. A conveyor belt 13 is sleeved on the pulley 12. A first support rod 14 is fixed on the conveyor belt 13. The first support rod 14 cooperates with the groove. The rotating sleeve 11 is connected to the transmission control mechanism and the trigger assembly.

[0042] It should be noted that, in the initial state, the first support rod 14 is located at the end of the stroke of one of the pulleys 12 towards one of the fixed plates 2. When it is necessary to control the movement of the cutting disc 9, the rotating sleeve 11 can be driven to rotate, thereby driving the pulley 12 to rotate. The pulley 12 will also drive the conveyor belt 13 to move, thereby driving the first support rod 14 to move. The first support rod 14 is located in the groove and slides in the groove, causing the receiving plate 10 with the groove to move, so that the cutting disc 9 moves along the length direction of the guide rod 6. When the first support rod 14 moves to the end of the stroke of the other pulley 12 towards the other fixed plate 2, the cutting disc 9 moves to the end of the stroke, and the pulley 12 continues to rotate, causing the cutting disc 9 to move towards the initial position. The above steps are repeated, thereby driving the cutting disc 9 to reciprocate.

[0043] Also includes:

[0044] Please see Figures 1-5A second rotating rod 30 is rotatably mounted on the base 1 and symmetrically arranged. A conveying roller 31 is fixed on the second rotating rod 30. A bidirectional rotating assembly connected to the second rotating rod 30 is provided on the horizontal plate 5. The bidirectional rotating assembly can control the two conveying rollers 31 to rotate in opposite directions through the second rotating rod 30. The bidirectional rotating assembly includes a first rotating rod 27 rotatably mounted on the horizontal plate 5 and symmetrically arranged. Two meshing gears 28 are fixed on the two first rotating rods 27 respectively. A first belt 26 is sleeved on the end of the first rotating rod 27 away from the base 1. A second belt 29 is sleeved on the end of the first rotating rod 27 facing the base 1. The second belt 29 is connected to the second rotating rod 30. The first belt 26 is connected to the transmission control mechanism.

[0045] Furthermore, when the wire mesh tube is placed on the support roller 4, it fits snugly against the conveyor roller 31. Under the action of the conveyor roller 31, the wire mesh tube is ensured not to shift during movement. When the wire mesh tube needs to be cut, the transmission control mechanism moves and controls the first belt 26 to move. The first belt 26 will drive the first rotating rod 27 connected to it to rotate, causing the gear 28 fixed on the first rotating rod 27 to rotate. Since the two gears 28 mesh with each other, the other first rotating rod 27 rotates, and the two first rotating rods 27 rotate in opposite directions. The two first rotating rods 27 will drive the second rotating rod 30 to rotate through the second belt 29, causing the conveyor roller 31 to rotate, and the two conveyor rollers 31 rotate in opposite directions. Under the action of the conveyor roller 31, the wire mesh tube is conveyed. When the wire mesh tube moves to the required position, the transmission control mechanism drives the first belt 26 to move again, causing the first rotating rod 27 to stop rotating, and the conveyor roller 31 to stop rotating.

[0046] Please see Figures 1-5 , Figures 7-9A transmission control mechanism is provided on the horizontal plate 5 and connected to the bidirectional rotation assembly and the drive assembly. The transmission control mechanism includes a slot 16 formed on the side wall of the rotating sleeve 11. A limiting ring 20 that cooperates with the slot 16 is movably installed inside the rotating sleeve 11. A spring 25 that abuts against the limiting ring 20 is sleeved on the rotating sleeve 11. A locking assembly that connects to the limiting ring 20 and the first belt 26 is provided on the horizontal plate 5. The limiting ring 20 is connected to the trigger assembly. The locking assembly includes a hollow rod 23 rotatably installed on the horizontal plate 5. A limiting tooth 24 is fixed at the end of the hollow rod 23. A movable rod 21 that penetrates the horizontal plate 5 and is movably connected to the hollow rod 23 is movably installed inside the rotating sleeve 11. A fixed tooth 22 that cooperates with the limiting tooth 24 is fixed at one end of the movable rod 21 facing the limiting tooth 24. The movable rod 21 is fixedly connected to the limiting ring 20.

[0047] Furthermore, in the initial state, spring 25 is compressed, causing the limiting ring 20 to be at the end of its stroke away from the horizontal plate 5, and the movable rod 21 to be at the end of its stroke away from the limiting tooth 24. At this time, the limiting tooth 24 and the fixed tooth 22 are separated. When it is necessary to control the movement of the wire mesh tube, the movement of the conveyor belt 13 will control the movement of the trigger component. Under the action of the trigger component, one of the limiting rings 20 is controlled to move along the length direction of the slot 16, and the movable rod 21 is driven to move. The movable rod 21 will also drive the fixed tooth 22 to move. When the limiting ring 20 moves to the end of its stroke, the fixed tooth... When the 22 moves to the position where it engages with the limiting tooth 24, the rotating sleeve 11 rotates, and drives the limiting ring 20 to rotate through the slot 16, which in turn drives the movable rod 21 to rotate. Since the limiting tooth 24 engages with the fixed tooth 22, the hollow rod 23 rotates synchronously, which drives the first rotating rod 27 to rotate through the first belt 26, causing the conveying roller 31 to rotate. When the wire mesh tube moves to the required position, the trigger component resets, the spring 25 is released elastically, and the limiting ring 20 and the movable rod 21 reset. The fixed tooth 22 separates from the limiting tooth 24, and the hollow rod 23 no longer rotates. The above steps are repeated to intermittently convey the wire mesh tube.

[0048] Please see Figures 1-5 , Figure 7 , Figure 8The horizontal plate 5 is also provided with a trigger component connected to the transmission control mechanism and the drive component. The trigger component can be activated when the drive component moves and control the bidirectional rotation component to rotate through the transmission control mechanism, thereby driving the second rotating rod 30 to rotate. The trigger component includes a fixed sleeve 19 fixedly installed at one end of the horizontal plate 5 facing the base 1 and symmetrically arranged. A fixed rod 18 is movably installed inside the fixed sleeve 19. A limit plate 17 is fixed at one end of the fixed rod 18 away from the fixed sleeve 19. A second support rod 15 that cooperates with the limit plate 17 is fixed on the conveyor belt 13. The limit plate 17 abuts against the limit ring 20.

[0049] In detail, the end face of the limiting plate 17 is inclined. In the initial state, the limiting ring 20 abuts against the limiting plate 17, and the second support rod 15 is separated from the limiting plate 17, so that the fixed rod 18 is located at the end of its stroke away from the fixed sleeve 19. When the wire bend needs to be conveyed, the conveyor belt 13 moves, driving the second support rod 15 to move. When the second support rod 15 moves to the position where it abuts against the inclined surface of the limiting plate 17, it drives the limiting plate 17 to move towards the horizontal plate 5, thereby driving the fixed rod 18 towards the fixed sleeve 19. During the movement of the 9th inner limit plate 17, the limit plate 17 will also drive the limit ring 20 to move, and through the movable rod 21, the fixed locking tooth 22 will move towards the limit locking tooth 24. When the limit ring 20 moves to the end of its stroke, the limit locking tooth 24 engages with the fixed locking tooth 22, so that the hollow rod 23 follows the rotating sleeve 11 to rotate, thereby causing the conveying roller 31 to rotate. When the second support rod 15 moves to the position where it is separated from the limit plate 17, the spring 25 is released elastically, thereby controlling the limit plate 17 to reset through the limit ring 20. The above steps are repeated to intermittently convey the wire mesh tube.

[0050] A diamond blade for improving the cutting quality of steel wire mesh pipes includes: a cutting disc 9 rotatably mounted on the movable plate 8.
