Description
Technical Field
The invention relates to the field of conductive cloth production equipment, in particular to an automatic adjusting and conveying device for copper plating of conductive cloth.
Background
The conductive cloth is used as a novel soft electromagnetic shielding material and is widely applied to electronic equipment such as mobile phones, computers and the like. The manufacturing principle is that a non-woven fabric is used as a base material to carry out vacuum sputtering of a nickel layer, and then a semi-finished product sputtered with the nickel layer is subjected to copper plating operation to obtain a material plated with nickel and copper. Firstly, nickel is sputtered on the conductive cloth, the conductive cloth (semi-finished conductive cloth) with a sputtered nickel layer is placed on a conductive cloth uncoiling roller shaft, the semi-finished conductive cloth is pulled by a conductive cloth uncoiling roller driven by a low-speed motor, the conductive cloth on the conductive cloth uncoiling roller shaft is transmitted to an electrolytic cell, the semi-finished conductive cloth is directly used as an electrode at one end of the electrolytic cell, copper is used as another electrode to perform electrolytic reaction of the copper, copper plating operation is performed on the nickel-plated conductive cloth again, and then the copper-plated conductive cloth is transmitted to a cleaning process through a guide transmission roller. Because electrically conductive cloth passes through in the electrolytic bath, can the more electrolytic bath solution of adhesion, set up and wash the pond and carry out the cleaning operation to electrically conductive cloth, the direction transfer roller conveys to wash the electrolyte that electrically conductive cloth surface was washed to the washing pond, passes through drying device stoving back again, rolls up the transfer roller by the book that second torque motor drove again and rolls up.
In the whole process of copper plating of the conductive cloth with the sputtered nickel layer, a low-speed motor in a production line is always kept to rotate at a constant speed relatively, so that the conductive cloth conveyed by the whole conveying roller is kept to be transmitted at a constant speed and with constant tension, the conductive cloth with the sputtered nickel layer needs to enter an electrolytic cell for electroplating after being uncoiled by a low-speed motor, if the rotating speed of the motor of the whole conveying mechanism is not constant, the tension for transmitting the semi-finished conductive cloth is too large or too small, after the conductive cloth electrolytic cell is used, copper plating on the surface of the conductive cloth is not uniform, so that one section of the conductive cloth after copper plating is uniform and uneven, the antistatic performance and the finished product quality of the conductive cloth are affected, and the requirements of customers cannot be met, and therefore the tension of the semi-finished conductive cloth during uncoiling needs to be matched with the tension of the conductive cloth during coiling.
When electrically conductive cloth tension was too big, because the material characteristic of electrically conductive cloth substrate non-woven fabrics, electrically conductive cloth has tensile properties and can be stretched, and the clearance can appear in the nickel layer of surface sputtering when electrically conductive cloth is stretched, directly influences the effect of the electrically conductive cloth of finished product after the copper facing again, leads to electrically conductive cloth performance greatly reduced, can't use even, can lead to electrically conductive cloth tensile fracture when serious. When the tension of the conductive cloth is not enough, the conductive cloth is loose, the deviation is caused on the conveying roller, the operation efficiency and the production efficiency of the equipment are greatly reduced, the copper plating effect of the whole section of the conductive cloth is not uniform, and the antistatic performance of the conductive cloth is poor.
In the whole uncoiling process of the conductive cloth roller, the conductive cloth roller on the conductive cloth uncoiling roller shaft is continuously conveyed, the number of layers of the conductive cloth roller is continuously reduced, and the diameter of the conductive cloth roller is continuously reduced; in the process of rolling the conductive cloth roller, the number of layers of the conductive cloth roller on the second torque motor conveying roller is continuously increased, and the diameter of the conductive cloth roller is also continuously increased, so that the diameter of the conductive cloth roller is continuously changed in the whole process, and the diameter of the conductive cloth roller influences the transmission speed of the conductive cloth. Even if the rotating speed of the low-speed motor is constant in the transmission process of the conductive cloth, the conveying speed of the conductive cloth is changed due to the change of the diameter of the conductive cloth roller. Therefore, the production quality of the conductive cloth can be ensured only by keeping the running speed of the conductive cloth in the copper plating quality range at a relatively constant speed through the continuous variable speed matching of the uncoiling motor in the whole transmission process, so that the automatic adjusting and conveying mechanism for copper plating of the conductive cloth is needed.

Frequency conversion transfer roller mechanism:
the variable-frequency conveying roller mechanism comprises a variable-frequency driving device and a variable-frequency conveying roller connected with the variable-frequency driving device; as shown in the attached drawings of the specification, fig. 1 and fig. 5, the variable frequency driving device comprises: the tension adjusting variable-frequency driving device is arranged at a starting point, and the winding variable-frequency driving device is arranged at a final point; the tension adjusting and frequency converting driving device at the starting point is used for adjusting the uncoiling tension of the semi-finished conductive cloth 8 roller, and the coiling and frequency converting driving device at the finishing point is used for coiling the finished conductive cloth 7 after copper plating.
The tension adjusting variable frequency driving device has the specific structure that: the conductive cloth uncoiling device comprises a conductive cloth uncoiling roll shaft 38 and a first torque motor 33 connected with the conductive cloth uncoiling roll shaft 38, wherein the first torque motor 33 drives the conductive cloth uncoiling roll shaft 38 to rotate so as to adjust the tension of the conductive cloth 7. The specific structure of the furling frequency conversion driving device is as follows: the second torque motor 34 is connected with the conductive cloth furling roll shaft 39, and the second torque motor 34 drives the conductive cloth furling roll shaft 39 to rotate. The torque motor can continuously operate at low speed even in a locked-rotor state without causing damage to the motor, and in the operating mode, the motor can provide stable torque for a load and the torque motor can also provide torque (braking torque) opposite to the operating direction. Because the whole transmission process of the conductive cloth 7 is very slow, the servo motor or other motors are selected to operate at low rotating speed for a long time, and the motor is damaged.
The second torque motor 34 drives the conductive cloth furling roller shaft 39 to rotate, the conductive cloth furling roller shaft 39 furls the copper-plated conductive cloth 7, meanwhile, the first torque motor 33 drives the conductive cloth uncoiling roller shaft 38 to rotate, the conductive cloth 7 is tensioned after the second torque motor 34 is furled, and the conductive cloth 7 on the uncoiling roller is transmitted to the electrolytic cell 36, the cleaning cell 37 and the drying device for processing through the guide conveying rollers of all levels of guide conveying roller mechanisms. When the copper-plated conductive cloth 7 passes through the electrolytic cell 36 and the cleaning cell 37, the conveying direction of the conductive cloth 7 needs to be switched, and the electrolytic solution on the surface of the conductive cloth 7 after copper plating is plated in the electrolytic cell 36 and cleaned, so that guiding conveying rollers are also arranged inside the bottom of the electrolytic cell 36 and inside the cleaning cell 37 to carry out reversing transmission on the conductive cloth 7.
The process of copper plating and winding of the conductive cloth 7 at the present stage is analyzed, when the first torque motor 33 drives the conductive cloth unwinding roller shaft 38 to rotate, the conductive cloth unwinding roller shaft 38 cannot pull the conductive cloth 7 to move backwards when rotating, and only the effect of adjusting the surface tension of the conductive cloth 7 in the transmission process can be achieved, and the transportation effect cannot be achieved. The second torque motor 34 is used for conveying the conductive cloth 7 and driving the conductive cloth furling roller shaft 39 to rotate, and the furling roller shaft rotates to drive the conductive cloth 7 to furl. When the conductive cloth 7 is plated with copper in the electrolytic cell 36, the quality of copper plating on the conductive cloth 7 can be ensured only by maintaining uniform transmission with constant tension, so that when the conductive cloth 7 is wound up by driving the conductive cloth take-up roller 39 through the second torque motor 34, transmission with constant speed and constant tension needs to be maintained. In order to avoid the influence of the multi-stage guiding conveying rollers between the conductive cloth furling roller shafts 39 on the uniform transmission when the conductive cloth furling roller shafts 39 furl the conductive cloth 7, the following structure is further improved:
further improvement:
a variable frequency driving device is arranged between the electrolytic cell 36 and the cleaning cell 37, so that the variable frequency driving device directly controls the operation speed of copper plating of the conductive cloth 7, the transmission speed of the conductive cloth 7 in the electrolytic cell 36 is controlled by accurately controlling the rotating speed of the variable frequency driving device, the semi-finished conductive cloth 8 slowly passes through the electrolytic cell 36 at a constant speed, sufficient reaction time is reserved for copper plating of the conductive cloth 7, and the quality of copper plating of the conductive cloth 7 is improved. The concrete structure includes: the frequency conversion driving device also comprises an uncoiling driving device, and the uncoiling driving device comprises two uncoiling rollers and an adjusting seat 24 assembly which are in close fit up and down;
as shown in fig. 1 and fig. 4 of the attached drawings of the specification, the upper decoiling roller and the lower decoiling roller which are tightly matched are arranged on the frame body 1 through the adjusting seat 24 assembly, the conductive cloth 7 penetrates through a gap between the upper decoiling roller and the lower decoiling roller, the conductive cloth 7 after being plated with copper is conveyed to the cleaning tank 37 by utilizing the friction force between the decoiling rollers and the conductive cloth 7, and the electrolyte on the surface of the conductive cloth 7 is cleaned. An uncoiling driving device is arranged on a roll shaft of the lower uncoiling roll 10, and the uncoiling driving device drives the roll shaft of the lower uncoiling roll 10 to further drive the upper uncoiling roll 9 to rotate, so that the conductive cloth 7 passing through the gap is conveyed to the next process. The roller connection of opening winding up roller 10 down is equipped with the gear, the gear passes through chain drive's mode, has the gear through the output shaft that sets up low-speed motor 35, and the gear revolve on the winding up roller 10 is opened under the chain drive for open winding up roller 10 down is through the rotation of low-speed motor 35 control, thereby the rotational speed of winding up roller 10 is opened in the control of the rotational speed through control low-speed motor 35, thereby the transmission rate of electrically conductive cloth 7 in electrolytic bath 36 is controlled. The low-speed motor 35 has the characteristics of small volume, low noise, maintenance-free performance and the like, the rotating speed is 0.83 r/min-300 r/min, and the low-rotating-speed motor can be realized without a speed reduction device.
In order to further accurately adjust the rotating speed of the lower winding roller 10, a speed measuring encoder 32 is connected to the shaft of the lower winding roller 10 of the variable-frequency conveying roller, the speed measuring encoder 32 is generally connected with the shaft, the pulse quantity of the speed measuring encoder 32 is fixed, when the shaft rotates, the speed measuring encoder 32 outputs pulses, a PLC control system or a counter receives the pulses, the total quantity of the received pulses in unit time is different according to different rotating speeds of the shaft, and the real speed meter/minute can be calculated according to the pulse quantity and the actual rotating length. The speed measuring encoder 32 measures and calculates the rotating speed of the shaft of the lower winding roller 10, and then the speed measuring encoder 32 measures the rotating speed of the variable frequency driving device, the speed measuring encoder 32 is connected with the computer system, so that the pulse frequency of the low-speed motor 35 is controlled by the computer system to monitor the rotating speed of the low-speed motor 35, and the change of the reaction time of the conductive cloth 7 in the electrolytic cell 36 caused by the large change of the rotating speed of the low-speed motor 35 is prevented, and the copper plating quality of the conductive cloth 7 is further influenced.
In the actual production process, the number of layers on the conductive cloth 7 rollers on the conductive cloth uncoiling roller shaft 38 and the conductive cloth coiling roller shaft 39 which are positioned at the two ends of the device is continuously changed along with time, and the number of layers of the conductive cloth 7 on the conductive cloth uncoiling roller shaft 38 is continuously reduced because the semi-finished conductive cloth 8 on the conductive cloth uncoiling roller shaft 38 needs to be plated with copper; since the conductive fabric 7 on the conductive fabric furling roller shaft 39 is the finished conductive fabric 7 and needs to be furled by the conductive fabric furling roller shaft 39, the number of layers of the conductive fabric 7 on the conductive fabric furling roller shaft 39 is increased continuously. Therefore, the radius of the semi-finished conductive cloth 8 on the conductive cloth unwinding roller shaft 38 is gradually reduced, and the diameter of the finished conductive cloth 7 on the conductive cloth winding roller shaft 39 is gradually increased, so that even if the rotating speeds of the low-speed motor 35 and the second torque motor 34 are constant, the transmission speed of the whole process of the conductive cloth 7 is affected by the diameter change of the conductive cloth 7. Therefore, the rotation speed of the first torque motor 33 is gradually increased, and the rotation speed of the second torque motor 34 is gradually decreased, so that the rotation speed of the low-speed motor 35 is reduced as much as possible in order to make the speed of the conductive cloth 7 passing through the electrolytic bath 36 uniform. The automatic control and regulation are realized through the following structures:
an automatic control section:
as shown in the attached figure 1 of the specification, a computer system is arranged in the variable frequency control cabinet 2, the computer system independently controls the motor rotating speed of the variable frequency driving device, the rotating speed of the motor is equal to 60 minutes multiplied by the power frequency divided by the pole pair number of the rotating magnetic field of the motor, so the pulse frequency of the motor power supply is in direct proportion to the rotating speed of the motor, and the rotating speed of the motor is controlled by controlling the pulse frequency of the motor power supply.
The locking shaft 3 of the start end guide conveying roller 4 and the locking shaft 3 of the end guide conveying roller 5 are provided with tension sensors 6, the whole process of the device for conveying the conductive cloth 7 is analyzed, the semi-finished conductive cloth 8 on the conductive cloth uncoiling roller shaft 38 is reversed by the guiding and conveying roller to enter the electrolytic cell 36, when the low-speed motor 35 drives the unwinding roller to drive the semi-finished conductive cloth 8 to pass through the electrolytic cell 36, the pressure of the tension of the conductive cloth 7 of the electrolytic cell 36 section is concentrated on the locking shaft 3 of the initial end guide conveying roller 4, because when the speed difference between the first torque motor 33 affected by the diameter of the roller of the conductive cloth 7 and the low speed motor 35 becomes smaller, the pressure of the tension of the conductive cloth 7 of the electrolytic bath 36 section gradually increases, therefore, a tension sensor 6 is arranged on the locking shaft 3 which leads the conveying roller 4 at the initial end to monitor the tension change value of the conductive cloth 7;
the tension sensor 6 arranged on the locking shaft 3 of the tail end guide conveying roller 5 is the same as that of the semi-finished conductive cloth 7, after copper plating is finished, the semi-finished conductive cloth 7 enters the cleaning pool 37 through the guide conveying roller, electrolyte on the surface is washed away, the second torque motor 34 and the low-speed motor 35 act together to transmit the conductive cloth 7, the low-speed motor 35 conveys the conductive cloth 7 after copper plating to the winding end of the second torque motor 34, when the speed difference between the second torque motor 34 and the low-speed motor 35 is increased, the locking shaft 3 positioned on the tail end guide conveying roller 5 is a concentrated point of the tensioning pressure of the conductive cloth 7, the numerical value measured by the tension sensor 6 is gradually increased, so that the tension sensor 6 is arranged to monitor the change value of the conductive cloth 7 at the winding end, the rotating speed of the second torque motor 34 is adjusted, and the rotating speed of the low-speed motor 35 is matched.
The computer system is in signal connection with the tension sensor 6, the tension sensor 6 measures tension data signals of the conductive cloth 7 on the surfaces of the initial end guide conveying roller 4 and the tail end guide conveying roller 5 in real time and transmits the tension data signals to the computer system, the computer system adjusts the output frequency of the variable frequency control cabinet 2 according to the received tension data signals, the rotating speeds of the first torque motor 33 and the second torque motor 34 are further controlled, the conveying speed of the conductive cloth 7 is adjusted, the tension of the conductive cloth 7 during transmission is adjusted, and the specific adjusting mode is as follows:
as for the whole copper plating process of the conductive cloth 7, the running speed of the conductive cloth 7 needs to be kept relatively constant within the time range of the copper plating quality, the time range of the copper plating quality is the time of the electrolytic reaction of the semi-finished conductive cloth 8 in the electrolytic cell 36, rather than only the semi-finished conductive cloth 7 needs to be kept to pass through the electrolytic cell 36 at a constant speed, the reaction time of the conductive cloth 7 needs to be controlled, the time range of the copper plating quality of the conductive cloth 7 is 40 +/-3 seconds, and the tension range detected by the tension sensor 6 is 200 +/-50N. Namely, the reaction time of the conductive cloth 7 in the electrolytic cell 36 is 37 s-43 s, the numerical range of the two tension sensors 6 is 150N-250N, and after the tension range of the tension sensors 6 is exceeded, the computer control system adjusts the speed according to the following original steps:
the monitoring principle of the tension sensor 6 is as follows: when the value detected by the tension sensor 6 on the locking shaft 3 of the initial end guide conveying roller 4 is higher than the range value, the rotating speed of the first torque motor 33 is increased by 5 percent, the rotating speed of the low-speed motor 35 is unchanged, and the rotating speed of the second torque motor 34 is unchanged; when the value detected by the tension sensor 6 on the locking shaft 3 of the initial end guide conveying roller 4 is lower than the range value, the rotating speed of the first torque motor 33 is reduced by 5 percent, the rotating speed of the low-speed motor 35 is unchanged, and the rotating speed of the second torque motor 34 is unchanged; when the detection value of the tension sensor 6 at the tail end is higher than the range value, the rotating speed of the first torque motor 33 is unchanged, the rotating speed of the low-speed motor 35 is unchanged, and the rotating speed of the second torque motor 34 is reduced by 5%; when the detected value of the front-end tension sensor 6 is lower than the range value, the rotating speed of the first torque motor 33 is unchanged, the rotating speed of the low-speed motor 35 is unchanged, and the rotating speed of the second torque motor 34 is increased by 5%.
For example, the current detection value of the front-end tension sensor 6 is 260N, 260N is higher than the copper plating tension range value of the conductive cloth 7, the rotating speed of the first torque motor 33 is increased by 5%, 5r/min is increased to 5.25r/min, the rotating speeds of the low-speed motor 35 and the second torque motor 34 are unchanged, if the current detection value of the tension sensor 6 is still larger than the range value, the rotating speed is continuously increased by 5%, 5.25r/min is increased to 5.56r/min, the value of the tension sensor 6 is 255N, the rotating speed is increased by 5% again until the value detected by the tension sensor 6 is within a reasonable range, and the speed increase is stopped. If the current detection value of the tension sensor 6 is 140N, the first torque motor 33 reduces the rotation speed by 5%, and the rotation speed at 6r/min is reduced to 5.7r/min until the tension sensor 6 falls within the normal value range. Since the tension sensor 6 is a real-time measurement value, and the first torque motor 33 and the second torque motor 34 have relatively low rotation speed, the sudden change of the measured tension is avoided, so that the tension in the transmission process of the conductive cloth 7 is adjusted by adjusting the rotation speed of the first torque motor 33 and the second torque motor 34 in time. If the sudden value is suddenly increased or decreased, alarm information is sent out to check the running state of the equipment.
A factor influencing the transmission speed of the conductive cloth 7 is also considered, namely the distance between the upper decoiling roller 9 and the lower decoiling roller 10, the pressure of the upper decoiling roller 9 acting on the lower decoiling roller 10, the friction force between the conductive cloth 7 and the lower decoiling roller 10, and the transmission speed of the conductive cloth 7. The pressure of the upper uncoiling roller 9 acting on the lower uncoiling roller 10 adjusts the distance between the upper uncoiling roller and the lower uncoiling roller 10 through the adjusting seat 24 assembly, so as to adjust the direct pressure of the upper uncoiling roller 9 and the lower uncoiling roller 10. The method is realized by the following specific structure:
as shown in the attached fig. 4 of the specification, the adjusting seat 24 assembly comprises a connecting block 23, an adjusting seat 24 and an adjusting bolt 25; the adjusting seat 24 assembly adjusts the gap between the upper uncoiling roller 9 and the lower uncoiling roller 10 by adjusting the position distance of the upper uncoiling roller in the adjusting seat 24. Adjusting seat 24 and support body 1 fixed connection, adjusting seat 24 top is equipped with adjustment screw 26, be equipped with the bearing in the connecting block 23, connecting block 23 passes through the bearing cooperation with the roll axle of opening a book and is connected for the roll axle of opening a book can be at connecting block 23 internal rotation. The connecting block 23 is arranged in the adjusting seat 24 in a sliding fit manner, so that the connecting block 23 slides in the adjusting seat 24, and the distance between the upper and lower winding rollers is adjusted. Go up connecting block 23 top and be equipped with sleeve 27, sleeve 27 fit in is equipped with limiting plate 28, limiting plate 28 and adjusting bolt 25 bottom fixed connection, adjusting bolt 25 and adjustment screw 26 threaded connection. When the gap between the upper and lower coiling rollers needs to be increased, the adjusting bolt 25 is screwed upwards, so that the bolt is matched with the threaded hole, the limiting plate 28 and the sleeve 27 are pulled to act, and the connecting block 23 is pulled upwards to slide upwards in the adjusting seat 24; when the clearance between the upper and lower opening rollers needs to be reduced, the bolt 25 is adjusted by the downward knob, so that the bolt drives the limiting plate 28 to act on the upper connecting block 23 downwards through the matching of the threaded hole, the connecting block 23 slides downwards, and the clearance between the upper and lower opening rollers is reduced. Adjust the clearance between the upper and lower opening roller through adjusting bolt 25, simple and practical avoids solving simple problem with complicated device, can be applicable to the electrically conductive cloth of different model thickness through adjusting the clearance between the upper and lower opening roller in addition for the practicality and the suitability of device are stronger.
Further improvement:
in order to facilitate electrically conductive cloth uncoiling roller shaft 38 and electrically conductive cloth furling roller shaft 39 to carry out quick dismantlement, change the roller that the electrically conductive cloth 7 reel of winding, so further set up quick detach structure and carry out quick installation:
the variable-frequency conveying roller mechanism further comprises a quick-release mounting assembly, and the quick-release mounting assembly comprises a quick-release structure clamping seat; the output shaft of the variable-frequency driving device is connected with one end of the roll shaft of the variable-frequency conveying roller through the coupler, a bearing is arranged on the roll shaft of the variable-frequency conveying roller, and the bearing is matched and locked with the quick-release structure clamping seat. The quick-release structure clamping seat is provided with a clamping groove 17 matched with a bearing of a variable-frequency conveying roller shaft, and the clamping groove 17 is divided into two parts and arranged in the quick-release structure clamping seat; so that the roller shaft wound with the conductive cloth 7 can be locked and fixed in the clamping seat without influencing the rotation. As shown in fig. 5 of the attached drawings of the specification, the quick release structure clamping seat specifically includes a fixed base 18, and a movable block 19 with one end hinged to the fixed base 18; the other end of the movable block 19 is provided with a limiting table 20, a movable groove 21 is formed in the same side of the fixed base 18 and the limiting table 20, a rotating shaft 22 is arranged in the movable groove 21, a locking stud is arranged on the rotating shaft 22 and provided with a locking nut, and the locking nut is matched and locked with the limiting table 20. The locking nut matched with the locking stud is screwed down, so that the locking nut presses the limiting table 20, and the movable block 19 hinged with the fixed base 18 is pressed tightly; when the roller shaft with the conductive cloth 7 needs to be replaced, the locking nut matched with the locking stud is unscrewed, and the rotating shaft 22 in the movable groove 21 is rotated, so that the locking nut is separated from the limiting table 20, and the movable block 19 is opened to replace the roller shaft of the conductive cloth 7.
A drying device:
after the conductive cloth 7 is washed away the electrolyte on the surface through the washing tank, a small amount of water is left on the surface of the conductive cloth 7, the conductive cloth 7 needs to be rolled up after being dried, and the following structures are arranged to dry the conductive cloth 7:
as shown in fig. 8 of the attached drawings of the specification, a drying device is further arranged on the frame body 1, and the drying device includes a housing 11 and a plurality of heating pipes 12 which are arranged on two sides of the housing 11 and are uniformly distributed from top to bottom; the heating pipe 12 is formed by uniformly distributing high-temperature resistance wires in a high-temperature resistant stainless steel seamless pipe, and densely filling crystalline magnesium oxide powder with good heat conduction performance and insulation performance in a gap part.
Because the electrolyte on both sides needs to be cleaned when the conductive cloth 7 is cleaned, the heating pipe 12 heats and dries the upper and lower sides of the conductive cloth 7 conveyed by the guide conveying roller during heating and drying, the water vapor evaporated during heating and drying is discharged through the exhaust port 13 on one side of the shell 11, and the end of the shell 11, which is far away from the exhaust port 13, is provided with the water outlet 14. As shown in fig. 8, the overall shape of the housing 11 is a wedge shape, and is divided into a high side and a low side, where the high side is the exhaust port 13 and the low side is the drain port 14. Because the water on the surface of the conductive cloth 7 is heated and evaporated, the water vapor is heated and expanded and discharged from the high side of the shell 11, and a small amount of water vapor is condensed into water drops under the action of gravity and discharged from the water outlet 14 at the low side and flows into the cleaning pool 37.
The exhaust port 13 and the water outlet 14 are movably connected with an adjusting plate 15, a long hole is formed in the adjusting plate 15, and the adjusting plate is fixed on the shell 11 through screws to adjust positions. The adjusting plate 15 is used for adjusting the height of the adjusting plate 15 according to the height of the conductive cloth 7 entering the shell 11 and the height of the conductive cloth 7 discharged from the shell 11, and if the height difference between the adjusting plate 15 and the conductive cloth 7 is too large, the drying effect of the heating pipe 12 on the conductive cloth 7 can be reduced, so that the heating evaporation rate is reduced.
As shown in the attached drawing fig. 3, the conductive cloth 7 is conveyed from the guiding conveying roller at the tail end of the cleaning tank 37 to the guiding conveying roller 5 at the tail end of the device, the conveying process is from low to high, the conductive cloth 7 is not wrinkled after being tensioned during conveying, and water can flow back to the cleaning tank 37 from the surface of the conductive cloth 7 through the height difference due to the smooth surface of the conductive cloth 7 after being plated with copper, so that the heating drying evaporation capacity of the heating pipe 12 is reduced. However, it should be particularly noted that in the above situation, in order to avoid that the conductive cloth 7 is too low in tension due to the speed difference between the low-speed motor 35 and the second torque motor 34, so that the conductive cloth 7 is stretched and falls onto the lower heating tube 12, and the conductive cloth 7 is damaged, and the finished conductive cloth 7 is scrapped, in the case that the surface of the conductive cloth 7 is tensioned, the following structure is further improved:
the side surface of the shell 11 is further provided with a plurality of anti-falling rods 16, the positions of the anti-falling rods 16 are shown in the attached drawing figure 8 of the specification, two anti-falling rods 16 are located in the middle section of the shell 11, and the positions of the anti-falling rods 16 are lower than the horizontal position conveyed by the conductive cloth 7 and higher than the position of the heating pipe 12 at the lower part. Because the surface tension of the conductive cloth 7 is too small, the conductive cloth 7 at the middle section firstly falls down in the transportation process, and the conductive cloth 7 with too small tension is supported by the anti-falling rod 16 arranged at the middle section, so that the conductive cloth 7 is prevented from being scalded by the heating pipe 12 below.
