Description

A metal iron chain processing iron wire feeding reel device

Technical field

The invention relates to the technical field of iron chain processing, and specifically relates to a metal iron chain processing iron wire feeding reel device.

Background technique

Iron chains mostly use machines to cut iron wires and process iron wires of equal lengths so that the iron wires are processed into iron rings of the same size and connected to each other, thereby achieving a processed iron chain. When transporting iron wires, they are usually The two feed trays are pressed against each other and the wire is placed in the middle. The rotation of the two feed trays drives the wire to move and cut and process it.

When the feed tray is used to transport the iron wire, if the iron wire is not rough-machined into a straight state or the wire is bent under the action of gravity due to the long length, the iron wire will swing when the feed tray is transporting the wire, thereby affecting the quality of the iron wire. The transportation efficiency of the iron wire affects the processing, so that the length of the iron wire is reduced when the iron wire is subsequently cut, which in turn causes the shorter iron wire to be unable to be processed into iron chains, resulting in a waste of material. At the same time, the feeding tray is used for a long time. The contact surface with the iron wire will be reduced due to loss, which will lead to lower transportation efficiency of the iron wire, further affecting the subsequent cutting and processing of the iron wire.

In view of the shortcomings of the existing technology, the present invention provides a metal iron chain processing iron wire feeding reel device, which has the advantage of preventing the reduction of the efficiency of transporting iron wire due to the swing of the iron wire and the reduction of the contact area between the feeding plate and the iron wire during iron wire transportation. , solves the problem of reduced efficiency of transporting wire due to wire swing and wear of the feed plate itself.

As an optimization, the outer panels are symmetrically installed on the front and rear sides of the inner panel, and the combination of the outer panels and the inner panels is installed symmetrically on the surface of the installation plate in pairs to prevent the iron wires from being inside the two outer panels. There was considerable shaking during transportation.

As an optimization, a gap is opened in the center of the outer plate. The cross-sectional size of the gap is larger than the cross-sectional size of the annular block. The annular block is fixedly installed at the gap and does not penetrate the outer plate. The driving rod is movably connected inside the annular block. One end of the driving rod close to the mounting plate is fixedly connected to the rotating end of the motor. After the motor is driven, the driving rod is driven to rotate.

As an optimization, the cavity is located at one end of the outer plates that are close to each other. The number of push rods is the same as the number of arc blocks, and the projection of the push rods on the surface of the arc block is located in the middle of the arc block, and the arc block rotates When the iron wire is driven to move, the push rod rotates to one end close to the iron wire and drives the pressing rod to move through the connecting rod on the left side of the trapezoidal block.

As an optimization, the cross-sectional shapes of the trapezoidal block and the top of the push rod are both right-angled trapezoids, and the two right-angled trapezoidal inclined plates are opposite. The vertical top of the push rod is located above the vertical bottom of the trapezoidal block. When the rod rotates, the trapezoidal block exerts forces in two directions: toward the cavity and away from the driving rod. The trapezoidal block is limited in the direction away from the driving rod, so that the trapezoidal block moves under the force toward the cavity.

As an optimization, the arc-shaped block is fixedly connected to the driving rod. A protruding block is provided at the proximal end of the arc-shaped block. The top of the connecting plate is located below the protruding block. When the connecting plate moves, the protruding block is pushed to drive the arc.

When an iron wire is placed on the top of the trigger block, the maximum static friction force between the trigger block and the iron wire is equal to the maximum static friction force between the driving rod and the annular block. When the trigger block and the iron wire are in full contact, they are subject to friction in two opposite directions and with the same magnitude. The cross-sectional size of the bump is smaller than the cross-sectional size of the slot, and the bump is engaged inside the slot so that the shaft sleeve is fixed.

The beneficial effects of the present invention are: the metal iron chain processing iron wire feeding reel device, when the arc block rotates to transport the iron wire, the ring block and the arc block rotate at the same speed, and the arc block contacts the iron wire and drives the iron wire to move At this time, the ring block drives the pressing rod to press the iron wire through the push rod, so that the iron wire is close to the inside of the inner plate, preventing the iron wire from swinging due to its own material and other reasons during transportation, which affects the transportation speed, and avoids the iron wire from causing damage when the transportation speed is reduced. The stamping device at the rear end reduces the length of the iron wire when it punches the iron wire periodically to prevent the cut iron wire from being processed into an iron chain normally.

At the same time, the metal iron chain processes the iron wire feeding reel device. When the arc-shaped block rotates for a long time to drive the iron wire to move, the arc-shaped block and the trigger block cannot close to the iron wire due to surface loss due to friction, which in turn causes the trigger block to be damaged by the iron wire. The reaction force is less than the force of the drive rod driving the ring block to rotate. At this time, the trigger block rotates under the action of the support rod and drives the shaft sleeve to move through the connecting line, which then drives the arc block to move toward the wire, making the arc block close to The iron wire increases the contact area with the iron wire, thereby preventing the arc block from being lost during long-term transportation, resulting in a reduction in transportation speed, and avoiding a reduction in the length of the cutting wire during subsequent processing of the iron wire.

A protruding block is provided at the proximal end of the arc-shaped block 12. The top of the connecting plate 14 is located below the protruding block. The connecting plate 14 When moving, the protruding block is pushed to drive the arc block 12 to move toward the edge of the outer plate 2. The left and right sides of the front and rear ends of the arc block 12 are rotatably connected to spring rods 13. The two ends of the spring rod 13 are respectively rotatably connected to adjacent The proximal end of the arc block 12 and the trigger block 24 will not swing under the action of the spring rod 13 and the arc block 12 when moving. The end of the connecting plate 14 away from the center of the inner plate 3 is fixedly connected to the driving rod 4. The driving rod 4. The rotation drives the connecting plate 14 to rotate. A chute is provided on the surface of the inner plate 3. The slider 15 is slidingly connected inside the chute. The connecting plate 14 can only move along the direction of the chute under the action of the slider 15.

A connecting plate 14 is movably connected to the interior of the proximal end of the arc block 12, a slider 15 is fixedly installed at the rear end of the center of the connecting plate 14, a support rod 16 is fixedly installed on the surface of the inner plate 3, and a shaft sleeve is slidably connected to the surface of the support rod 16 17. The left and right sides of the sleeve 17 are rotatably connected with telescopic rods 18. The telescopic rod 18 and the support rod 16 form an acute angle. When the axle sleeve 17 moves, it can drive the connecting plate under the action of the telescopic rod 18 and the support rod 16. 14 moves toward the edge of the inner panel 3, the tops of the telescopic rod 18 and the lever 20 are fixedly connected through the fixed rod and the center line of the telescopic rod 18 and the lever 20 is a straight line, the connecting pin 19 is fixedly connected to the surface of the inner panel 3, the telescopic rod 18 and the lever 20 rotate with the connecting pin 19 as the center of the circle. The end of the telescopic rod 18 away from the sleeve 17 is rotatably connected to the connecting pin 19, and the end of the connecting pin 19 away from the telescopic rod 18 is rotatably connected to the lever 20.

A winding group 21 is fixedly installed on the surface of the support rod 16, and a spiral reed 22 is movably connected inside the winding group 21. The two ends of the spiral reed 22 are fixedly connected with connecting wires, and the connecting wires are connected to the shaft sleeve 17 and the fixed pin respectively. 25 is fixedly connected, a support rod 23 is fixedly installed on the surface of the annular block 10, and a trigger block 24 is fixedly installed at one end of the support rod 23 away from the annular block 10. The top of the trigger block 24 and the top of the arc block 12 are at the same vertical height.

Arc-shaped grooves are provided at the tops of the arc-shaped block 12 and the trigger block 24. The iron wire is placed inside the groove to be more stable during transportation. When the iron wire is placed at the top of the trigger block 24, the maximum static friction between the trigger block 24 and the iron wire is equal to the driving force. The maximum static friction force between the rod 4 and the annular block 10. When the trigger block 24 is in full contact with the iron wire, it is stationary due to friction forces of the same magnitude and in opposite directions. The cross-sectional size of the bump 28 is smaller than the cross-sectional size of the slot 29. The bump 28 is engaged inside the slot 29 so that the sleeve 17 is fixed, and a fixing pin 25 is fixedly installed on the front end of the support rod 23;

An inner groove 26 is provided inside the shaft sleeve 17 . A return spring 27 is fixedly installed at the top of the inner groove 26 . A bump 28 is fixedly installed at the bottom of the return spring 27 . A retaining groove 29 is provided at the top of the support rod 16 .

When in use, place the iron wire on the top of the inner plate 3 between the two outer plates 2, drive the motor to rotate the driving rod 4, and the driving rod 4 rotates to drive the fixedly connected arc block 12 to rotate. When the arc block 12 rotates, The iron wires on the top of the inner plate 3 rub against each other, thereby driving the iron wires to be transported forward. When the motor drives the driving rod 4 to rotate for a certain period, the stamping equipment cuts and processes the iron wires;

When the drive rod 4 rotates, the annular block 10 movablely connected to the surface of the drive rod 4 is rubbed and rotates with the drive rod 4. When the annular block 10 rotates, it drives the fixedly connected push rod 11 to rotate. When the arc block 12 rotates to the inner plate 3 When the push rod 11 rotates to the top, the push rod 11 pushes the trapezoidal block 9 so that the trapezoidal block 9 moves toward the inside of the outer panel 2. When the trapezoidal block 9 moves, the connecting rod 8 drives the pressing rod 7 toward the inner panel 3. Move, and then push the moving wire through the pressing rod 7, so that the vertical movement of the wire moving direction is limited, preventing the wire from swinging during transportation due to its non-straightness, and then causing the arc block 12 to rotate to drive the wire The efficiency of movement is higher, which prevents the iron wires of different specifications from swinging during transportation, causing the movement speed to decrease, which in turn causes the length of the iron wire to gradually become shorter when the stamping device cuts the iron wire, making it impossible to process the iron chain normally, so that the iron chain cannot be processed normally during transportation. The effect of transporting wires of different specifications at a faster rate;

The arc block 12 constantly rubs against the iron wire while rotating and driving the iron wire for transportation. The top heights of the arc block 12 and the trigger block 24 are the same, so the trigger block 24 is subject to a tangential force in the opposite direction of the movement of the iron wire. At the same time, the annular block 10 Affected by the tangential force in the moving direction of the iron wire generated when the drive rod 4 rotates, the maximum static friction force between the trigger block 24 and the iron wire is equal to the maximum static friction force between the drive rod 4 and the annular block 10, so the trigger block 24, the support rod 23 and the annular block 10 The combination of the block 10 is subjected to two forces of opposite directions and equal magnitude, thereby causing the trigger block 24 to remain stationary. After long-term use, the surfaces of the arc-shaped block 12 and the trigger block 24 are rubbed smoother. At this time, the trigger block 24 The friction between the wire and the iron wire is reduced;

The trigger block 24, the support rod 23 and the annular block 10 rotate with the driving rod 4. When the support rod 23 rotates, the connecting line on its surface pulls the spiral reed 22 inside the winding group 21, and the spiral reed 22 rotates and passes through the other end. The connecting line pulls the sleeve 17 to move toward the center of the inner plate 3. When the sleeve 17 moves, the bump 28 compresses the return spring 27. When the bump 28 moves to the inside of the adjacent slot 29 closer to the center of the inner plate 3, The sleeve 17 is fixed on the surface of the support rod 16. When the sleeve 17 moves, the combination of the telescopic rods 18 and the lever 20 on the left and right sides rotates with the connecting pin 19 as the center of the circle, thereby driving the connecting plate 14 that is rotationally connected to the lever 20. Move toward the wire;

When the connecting plate 14 moves, it pushes the arc block 12 to move, and then the friction between the arc block 12 and the iron wire increases, so that the support rod 23 no longer moves with the arc block 12. At this time, the spiral spring 22 shrinks to complete the tightening of the connecting rope, so that the arc-shaped block 12 transports the iron wire at its current position, thereby preventing the arc-shaped block 12 from reducing the transport speed due to reduced friction during long-term transport of the wire.

To sum up, in this metal chain processing iron wire feeding reel device, when the arc block 12 rotates and transports the iron wire, the rotation speeds of the ring block 10 and the arc block 12 are the same, and the arc block 12 contacts and drives the iron wire. When the iron wire moves, the ring block 10 drives the pressing rod 7 to press the iron wire through the push rod 11, so that the iron wire is close to the inside of the inner plate 3, preventing the iron wire from swinging due to its own material and other reasons during transportation, affecting the transportation speed, and preventing the iron wire from being transported during transportation. When the speed decreases, the length of the iron wire is reduced when the rear-end stamping device periodically punches the iron wire, preventing the cut iron wire from being processed into an iron chain normally.

At the same time, when the metal iron chain processing iron wire feeding reel device drives the iron wire to move through the long-term rotation of the arc-shaped block 12, the arc-shaped block 12 and the trigger block 24 cannot adhere to the wire due to surface loss due to friction, which in turn causes the trigger block The reaction force of the iron wire 24 is less than the force of the driving rod 4 to drive the annular block 10 to rotate. At this time, the trigger block 24 rotates under the action of the support rod 23 and drives the shaft sleeve 17 to move through the connecting line, thereby driving the arc block 12 toward The direction of the iron wire moves so that the arc-shaped block 12 is close to the iron wire and increases the contact area with the iron wire, thereby preventing the arc-shaped block 12 from being lost during long-term transportation and causing a reduction in the transportation rate, and avoiding the reduction in the length of the cutting wire during subsequent processing of the iron wire. .
