Description

Technical Field

[0001] This invention belongs to the field of zinc material manufacturing technology, specifically relating to an automatic metering device for online zinc wire production. Background Technology

[0002] Zinc wire, as an important metallic material, is widely used in electronic component manufacturing, battery electrode materials, and other fields. Its production process requires a continuous drawing process to gradually draw large-diameter zinc wire blanks into fine zinc wires that meet customer requirements. In zinc wire drawing production, length measurement is a key quality control step, and subsequent processes need to cut or wind and package the zinc wires to a fixed length based on the measurement results.

[0003] Currently, the industry commonly uses a combination of encoder and measuring guide wheel for zinc wire length measurement. The encoder is coaxially fixed to the measuring guide wheel via a coupling, and the encoder's electrical signal output is electrically connected to a PLC controller. The zinc wire output from the drawing equipment adheres closely to the outer circumference of the measuring guide wheel during transport. The friction between the zinc wire and the measuring guide wheel drives the wheel to rotate synchronously in the direction of wire transport. The encoder converts the mechanical rotation of the measuring guide wheel into an electrical signal. The PLC controller receives this signal, calculates in real time, and outputs the actual transported length of the zinc wire, thus achieving zinc wire length measurement.

[0004] However, because the zinc wire changes length due to stretching deformation during the drawing process, it cannot fit with the metering guide wheel during feeding, resulting in slippage. Consequently, the actual length of the zinc wire is greater than the measured length of the metering guide wheel, causing a length measurement deviation. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides an automatic metering device for online zinc wire production. This invention adds a synchronization mechanism, which clamps and wraps the zinc wire with a clamping belt having a high coefficient of friction, causing the zinc wire to move synchronously with the clamping belt. The clamping belt indirectly drives the metering guide wheel to have the same amount of movement as the zinc wire, ensuring that the encoder accurately collects the true length of the zinc wire.

[0006] The specific technical solution adopted in this invention is as follows:

[0007] An automatic metering device for online zinc wire production includes a worktable and a metering guide wheel and an encoder mounted on the worktable. The encoder and the metering guide wheel are coaxially arranged. The electrical signal output terminal of the encoder is connected to a PLC controller. A synchronization mechanism is also provided on the worktable. The synchronization mechanism includes a clamping belt and a guide wheel assembly. The clamping belt is attached to the metering guide wheel by means of the guide wheel assembly and drives the metering guide wheel to rotate synchronously. The opening and closing side of the clamping belt faces the metering guide wheel and has the freedom to open and close. The opening and closing side of the clamping belt allows the zinc wire to enter the clamping channel of the clamping belt. The zinc wire moves synchronously with the clamping belt by being clamped and wrapped by the clamping belt.

[0008] The clamping band has a hollow tubular structure, and the hollow cavity of the clamping band forms a clamping channel. The cross-section of the clamping band has a claw-like structure, and the opening of the claw structure is the opening and closing side of the clamping band.

[0009] The clamping belt has longitudinal and transverse slits on its opening and closing sides. The longitudinal slits are arranged in multiple sets at intervals and are perpendicular to the axis of the clamping belt. The transverse slits pass through both ends of the clamping belt and are parallel to the axis of the clamping belt. The clamping belt between adjacent longitudinal slits forms a clamping unit. When the clamping unit passes through the guide wheel set, it bends and opens along the transverse slit to allow the zinc wire to enter the clamping channel. The zinc wire has the freedom to move synchronously with the clamping belt by means of the clamping and wrapping of the clamping unit.

[0010] The depth of the longitudinal cut is 2 / 3 to 3 / 4 of the diameter of the clamping band, and the distance between adjacent longitudinal cuts is 1-2 cm.

[0011] The clamping belt forms a circular motion trajectory with the help of the guide wheel group. The guide wheel group is provided with at least three sets. The first guide wheel, the second guide wheel and the third guide wheel are arranged in a triangular shape. The first guide wheel and the second guide wheel are respectively located close to the input end and the output end of the metering guide wheel. The opening and closing side of the clamping belt is in close contact with the metering guide wheel with the guidance of the first guide wheel and the second guide wheel. The clamping belt and the metering guide wheel rotate synchronously in opposite directions.

[0012] The workbench is provided with a feeding chute and a feeding cover plate. The gap between the feeding chute and the feeding cover plate forms a feeding channel. The feeding channel has an arc structure. The output end of the feeding channel is connected to the clamping channel of the belt at the first guide wheel.

[0013] The workbench is provided with a discharge chute and a discharge cover plate. The gap between the discharge chute and the discharge cover plate forms a discharge channel. The input end of the discharge channel is connected to the clamping channel of the belt at the second guide wheel.

[0014] The workbench is also equipped with a micro switch. The spring of the micro switch abuts against the connecting side of the clamping belt, and the spring and the metering guide wheel clamp the clamping belt together.

[0015] The clamping strap is made of rubber.

[0016] The beneficial effects of this invention are:

[0017] 1. The present invention includes a synchronization mechanism. Due to the high coefficient of friction of the clamping belt material, the zinc wire can be clamped and wrapped by the clamping belt, allowing the zinc wire to move synchronously with the clamping belt. That is, the length of movement of the zinc wire is equal to the length of movement of the clamping belt. The clamping belt then drives the metering guide wheel to rotate synchronously. Since the clamping belt is always taut and its material has a high coefficient of friction, slippage can be avoided. This ensures that the rotation of the metering guide wheel is consistent with the actual movement of the zinc wire, ensuring that the encoder accurately collects the true length of the zinc wire.

[0018] 2. The clamping belt in this invention is composed of multiple interconnected clamping units. Since the clamping units are independent of each other, when the first clamping unit passes the first guide wheel at the input end of the metering guide wheel and is bent and opened with a transverse slit, the other clamping units are still in a closed state. When the first clamping unit opens, it passes the zinc wire and allows the zinc wire to enter the clamping channel. As the first clamping unit continues to rotate, the first clamping unit moves away from the first guide wheel and returns to a straight cylindrical structure. That is, the opening and closing side of the first clamping unit closes again and clamps and wraps the zinc wire inside, thereby carrying the zinc wire through the metering guide wheel. When the first clamping unit passes the second guide wheel at the output end of the metering guide wheel, the first clamping unit is bent again by the second guide wheel, and the opening and closing side opens again, thereby allowing the zinc wire to detach from the clamping belt and be discharged. Through the above-described workflow, the synchronous movement of the clamping belt and the zinc wire is achieved, thereby ensuring that the movement of the clamping belt can reflect the actual length of the zinc wire and ensuring that the encoder accurately collects the true length of the zinc wire.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] Specific embodiments, such as Figure 1-6 As shown, the present invention provides an automatic metering device for online zinc wire production, including a workbench 1, a metering guide wheel 2 and an encoder disposed on the workbench 1. The encoder and the metering guide wheel 2 are coaxially arranged, and the electrical signal output terminal of the encoder is connected to a PLC controller. A synchronization mechanism is also provided on the workbench 1. The synchronization mechanism includes a clamping belt 3 and a guide wheel assembly. The clamping belt 3 is attached to the metering guide wheel 2 by means of the guide wheel assembly and drives the metering guide wheel 2 to rotate synchronously. The opening and closing side of the clamping belt 3 faces the metering guide wheel 2 and has the freedom to open and close. The opening and closing side of the clamping belt 3 allows the zinc wire to enter the clamping channel of the clamping belt 3. The zinc wire moves synchronously with the clamping belt 3 by means of the clamping and wrapping of the clamping belt 3.

[0028] Because the zinc wire undergoes length changes during the drawing process, it cannot adhere to the metering guide wheel 2 during feeding, resulting in slippage. Consequently, the actual length of the zinc wire is greater than the measured length of the metering guide wheel 2, causing a length measurement deviation.

[0029] Therefore, a synchronization mechanism is added to this invention. Since the clamping belt 3 itself has a high coefficient of friction, when the zinc wire is clamped and wrapped by the clamping belt 3, the zinc wire can move synchronously with the clamping belt 3. That is, the length of movement of the zinc wire is equal to the length of movement of the clamping belt 3. The clamping belt 3 then drives the metering guide wheel 2 to rotate synchronously. Since the clamping belt 3 is always in a taut state and its material has a high coefficient of friction, the phenomenon of slippage between the clamping belt 3 and the metering guide wheel 2 can be avoided. This ensures that the rotation amount of the metering guide wheel 2 is consistent with the actual movement amount of the zinc wire, ensuring that the encoder accurately collects the true length of the zinc wire.

[0030] like Figure 3-6 As shown, the clamping belt 3 has a hollow tubular structure, the hollow cavity of the clamping belt 3 forms a clamping channel, the cross section of the clamping belt 3 has a claw-like structure, and the opening of the claw structure is the opening and closing side of the clamping belt 3.

[0031] When the clamping belt 3 passes the input end between the first guide wheel 6 and the metering guide wheel 2, the opening and closing side of the clamping belt 3 opens like a claw. After the zinc wire enters, it closes again and clamps the zinc wire, which can ensure that the zinc wire is firmly clamped and avoid relative slippage between the clamping belt 3 and the zinc wire.

[0032] like Figure 3-6 As shown, the clamping belt 3 has longitudinal slits 4 and transverse slits 5 on its opening and closing side. The longitudinal slits 4 are arranged in multiple sets at intervals and the direction of the longitudinal slits 4 is perpendicular to the axis of the clamping belt 3. The transverse slits 5 pass through both ends of the clamping belt 3 and the direction of the transverse slits 5 is parallel to the axis of the clamping belt 3. The clamping belt 3 between adjacent longitudinal slits 4 forms a clamping unit. When the clamping unit passes through the guide wheel set, it bends and opens along the transverse slits 5 to allow the zinc wire to enter the clamping channel. The zinc wire has the freedom to move synchronously with the clamping belt 3 by means of the clamping and wrapping of the clamping unit.

[0033] Since the clamping units are independent of each other, when the first clamping unit passes the first guide wheel 6 at the input end of the metering guide wheel 2 and is bent to open the transverse slit 5, the other clamping units are still in a closed state. When the first clamping unit opens, it passes the zinc wire and allows the zinc wire to enter the clamping channel. As the first clamping unit continues to rotate, the first clamping unit moves away from the first guide wheel 6 and returns to a straight cylindrical structure. That is, the opening and closing side of the first clamping unit closes again and clamps and wraps the zinc wire inside, thereby carrying the zinc wire through the metering guide wheel 2. When the first clamping unit passes the second guide wheel 7 at the output end of the metering guide wheel 2, the first clamping unit is bent again by the second guide wheel 7, and the opening and closing side opens again, thereby allowing the zinc wire to detach from the clamping belt 3 and be discharged. Through the above workflow, the synchronous movement of the clamping belt 3 and the zinc wire is achieved, thereby ensuring that the movement of the clamping belt 3 can reflect the actual length of the zinc wire and ensuring that the encoder accurately collects the true length of the zinc wire.

[0034] In addition, the first guide wheel 6 and the second guide wheel 7 are provided with ring-shaped positioning protrusions along the circumferential direction. The positioning protrusions are located on the same plane as the transverse cut of the clamping belt 3. The positioning protrusions ensure that the clamping unit will open along the transverse cut 5.

[0035] The depth of the longitudinal cut 4 is 2 / 3 to 3 / 4 of the diameter of the clamping strap 3, and the distance between adjacent longitudinal cuts 4 is 1-2 cm.

[0036] If the longitudinal cut 4 is too shallow, the clamping belt 3 will not be able to open when passing the guide roller assembly. If the longitudinal cut 4 is too deep, the clamping belt 3 will open at too large an angle when passing the guide roller assembly, causing it to fold over and preventing it from closing again. Furthermore, an excessively deep longitudinal cut 4 will weaken the back connection point of the clamping belt 3, making it prone to breakage. The distance between adjacent longitudinal cuts 4 is the length of the clamping unit.

[0037] like Figure 1-2 As shown, the clamping belt 3 forms a circular motion trajectory with the help of the guide wheel group. The guide wheel group is provided with at least three sets, with the first guide wheel 6, the second guide wheel 7 and the third guide wheel 8 arranged in a triangular shape. The first guide wheel 6 and the second guide wheel 7 are respectively located close to the input end and the output end of the metering guide wheel 2. The opening and closing side of the clamping belt 3 is in close contact with the metering guide wheel 2 with the guidance of the first guide wheel 6 and the second guide wheel 7. The clamping belt 3 and the metering guide wheel 2 rotate synchronously in opposite directions.

[0038] The clamping belt 3 is supported by the guide wheel assembly to form a circular motion trajectory. The clamping belt 3 can rotate cyclically to realize the continuous feeding of zinc wire, which meets the continuous production requirements of zinc wire. The design position of the first guide wheel 6 and the second guide wheel 7 causes the clamping belt 3 between the first guide wheel 6 and the second guide wheel 7 to be bent and pressed. On the one hand, it ensures that the clamping belt 3 is in close contact with the metering guide wheel 2. On the other hand, it plays a tensioning role for the clamping belt 3, ensuring that the contact section between the clamping belt 3 and the metering guide wheel 2 always maintains a stable tension, ensuring that the clamping belt 3 and the metering guide wheel 2 are synchronized and there is no risk of slippage.

[0039] The third guide wheel is the driving wheel and is connected to the output end of the drive motor. The first guide wheel, the second guide wheel, and the metering guide wheel are all driven wheels, which are driven by the transmission of the clamping belt.

[0040] like Figure 1-2 As shown, the workbench 1 is provided with a feeding chute 9 and a feeding cover plate 10. The gap between the feeding chute 9 and the feeding cover plate 10 forms a feeding channel. The feeding channel has an arc-shaped structure. The output end of the feeding channel is connected to the clamping channel of the clamping belt 3 at the first guide wheel 6.

[0041] The feed channel guides the zinc wire at the input end of the metering device, ensuring that the zinc wire accurately enters the clamping channel at the six openings of the first guide wheel, thus preventing the zinc wire from deviating from the expected trajectory and failing to enter the clamping channel due to shaking.

[0042] like Figure 1-2As shown, the workbench 1 is provided with a discharge chute 11 and a discharge cover plate 12. The gap between the discharge chute 11 and the discharge cover plate 12 forms a discharge channel. The input end of the discharge channel is connected to the clamping channel of the clamping belt 3 at the second guide wheel 7.

[0043] The discharge channel allows for the straightening of zinc wires and strengthens lateral restraint, preventing the zinc wires from shifting during discharge and causing subsequent zinc wires to shift as a whole.

[0044] like Figure 1-2 As shown, a micro switch 13 is also provided on the workbench 1. The spring 14 of the micro switch 13 abuts against the connecting side of the clamping belt 3. The spring 14 and the metering guide wheel 2 together clamp the clamping belt 3.

[0045] In actual operation, the zinc wire may fail to enter the clamping channel. If this is not detected in time, the measurement data for the entire period will be inaccurate, seriously affecting the accuracy of the measurement data.

[0046] Therefore, a micro switch 13 is provided. When the zinc wire enters the clamping channel normally, the thickness of the clamping belt 3 will not change, the micro switch 13 will not be triggered, and the metering device will operate normally. When the zinc wire does not enter the clamping channel, that is, when the zinc wire is between the clamping belt 3 and the metering guide wheel 2, the micro switch 13 is triggered due to the change in the distance between the spring 14 and the metering guide wheel 2. At this time, the drive motor is turned off, the metering device stops moving, thus ensuring that the metering data before the micro switch 13 is triggered is accurate. Then, the operator makes adjustments, puts the derailed zinc wire into the clamping channel, restarts the metering device, and continues to perform metering.

[0047] The clamping strap 3 is made of rubber.

[0048] The rubber material has a high coefficient of surface friction. When the clamping belt 3 comes into contact with the zinc wire, the high coefficient of friction can generate sufficient static friction force to prevent the zinc wire from sliding relative to the clamping belt 3 during the clamping and conveying process, and to ensure that the moving length of the zinc wire is completely consistent with the moving length of the clamping belt 3.
