Description

Technical Field

[0001] The utility model relates to the technical field of cable reel equipment, in particular to a cable winding reel. Background Art

[0002] The electric drive winding drum used in cable production, etc., has the main function of driving the winding cable production equipment to produce continuously output cables through the replaceable drum under the driving force of the motor reduction mechanism. After the drum is suitable for winding the cable, the drum after winding the cable is removed and replaced with a new drum to continue winding the subsequent cables (the shaft rods on both sides of the drum are sleeved from top to bottom in the sleeve connected to the rotating shaft of the motor reduction mechanism of the electric drive winding drum, and the driven shaft rod sleeve of the other end support seat. The upper end and the inner end of the sleeve are open structures. After the shaft rods on both sides of the drum are sleeved in the two sleeves, bolts are passed through the sleeves and the shaft rod openings and fixed with nuts to fix the drum between the rotating shaft of the motor reduction mechanism and the inner side of the support seat). The electric drive winding drum is equipped with a guide mechanism at its front end. Under the control of the main control system, the guide mechanism drives the cable located between the two guide pulleys (the cable is located between the wheel grooves of the two pulleys) to move left and right through a small motor reduction mechanism, a lead screw, etc., so that the cable can be evenly wound on the drum. Under the control of the main control system, the motor reduction mechanism of the electric drive winding drum rotates from fast to slow in winding speed, so that the speed of the drum winding the cable is consistent with the speed of the cable output of the cable production equipment, ensuring the smooth progress of the cable winding work (initialization, the drum has no winding cable or the winding cable is less and the outer diameter is smaller, the main control system controls the drum to rotate relatively fast, after winding, the outer diameter of the drum gradually increases, and the main control system controls the drum to rotate slowly; there are also electric drive winding drums whose motor reduction mechanism power output end (shaft) and the shaft driving the drum to rotate are driven by rubber wheels, the motor reduction mechanism drives the active rubber wheel to rotate at a constant speed, the active rubber wheel friction drives the driven rubber wheel at the side end of the shaft to rotate, when the cable winding speed is fast and tightened, the active rubber wheel and the driven rubber wheel slip, and the drum does not rotate, on the contrary, when the cable winding speed is slow and loose, the active rubber wheel drives the driven rubber wheel to rotate, and the drum rotates to wind up the cable). In order to achieve the required length of the reeled cable, a meter is usually installed on the front end of the drum or guide mechanism to count the length. The staff visually observes the length data of the meter as needed. When the length is sufficient, the staff turns off the main power and removes the drum after the reeled cable.

[0003] Although the existing electric drive winding drum meets the actual production needs to a certain extent, there are still some problems that need to be improved due to structural limitations. Specifically, since the working power of the motor reduction mechanism is turned off by manually observing the length data of the meter counter and manually controlling the length of the meter counter, it will bring inconvenience to the staff and increase the labor intensity. In extreme cases, when the staff does not observe the meter counter in time after the meter count is reached, there is a probability that the length of the cable wound on the drum is too long and the cable needs to be unwound later, so it will more or less have an adverse effect on the actual production efficiency. In summary, it is particularly necessary to provide a cable winding drum that can automatically count the length of the cable continuously wound on the drum and automatically turn off the main power supply when the required length is reached.

[0017] Figure 1 , 2 As shown in Figure 3, the new type of electric drive winding drum body 1 is used for cable production and the like. The replaceable drum body 102 drives the winding cable production equipment to produce continuously output cables 7 under the driving force of the motor reduction mechanism 103. After the drum body 102 is suitable for winding the cable, the drum body 102 after winding the cable is removed and replaced with a new drum body to continue winding the subsequent produced cables (the shaft rods at both sides of the drum body are sleeved from top to bottom in the sleeve 104 connected to the rotating shaft of the motor reduction mechanism of the electric drive winding drum, and in the driven shaft rod sleeve 104 of the support seat at the other end, and the upper end of the sleeve and The inner end is an open structure. After the shaft rods at both side ends of the cylinder 102 are sleeved in the two sleeves, bolts 105 are passed through the sleeves and the shaft rod openings and fixed with nuts to fix the cylinder between the rotating shaft of the motor reduction mechanism and the inner side of the support seat); the electric drive winding drum is equipped with a guide mechanism 106 at its front end. Under the control of the main control system, the guide mechanism 106 drives the cable 7 located between the two guide pulleys (the cable is located between the wheel grooves of the two pulleys 21) to move left and right through a small motor reduction mechanism, a screw, etc., so that the cable 7 can be evenly wound on the cylinder 102. Under the control of the main control system, the motor deceleration mechanism of the electric drive winding drum body 1 rotates from fast to slow at a winding speed, so that the speed of the drum winding the cable is consistent with the speed of the cable output by the cable production equipment, ensuring the smooth progress of the cable winding work (initially, the drum has no winding cable or the winding cable is less and the outer diameter is smaller, and the main control system controls the drum to rotate relatively fast. After winding, the outer diameter of the drum gradually increases, and the main control system controls the drum to rotate gradually slower; there are also electric drive winding drums whose motor deceleration mechanism power output end (rotating shaft) and the shaft rod driving the drum to rotate are driven by rubber wheels, and the motor deceleration mechanism drives the active rubber wheel to rotate at a constant speed, and the active rubber wheel friction drives the driven rubber wheel at the side end of the shaft rod to rotate. When the cable winding speed is fast and tightened, the active rubber wheel and the driven rubber wheel slip, and the drum does not rotate. On the contrary, when the cable winding speed is slow and loose, the active rubber wheel drives the driven rubber wheel to rotate, and the drum rotates to wind up the cable). The above is an existing mature technology, and this application will not repeat it, nor will it provide any protection for the above technical points.

[0018] Figure 1 , 2As shown in Figure 3, after turning on the power switch D, the 3rd and 4th pins of the power module W1 output a stable DC 12V power supply to enter the power input end of the statistical circuit and the control circuit. After the staff turns on the power switch D1 of the portable reminder circuit, the wireless receiving circuit module W4 will be powered on. The 220V AC power supply enters the main power input end of the electric drive winding reel body 1 through the control power input end and the normally closed contact end of the relay K2, and the electric drive winding reel body 1 (M) reels the cable normally. The electric drive winding drum body 1 winds up the cable 7. When the cable is wound on the drum body 102 between the two pulleys 21, the cable will drive a pulley 21 connected to the shaft of the generator M to rotate. The generator M outputs an AC power supply of about 6V and enters the power input end of the bridge pile W2. The bridge pile W2 outputs a DC power supply (filtered by capacitor C1) which is divided by the adjustable resistor RP1 and the resistor R1, and the resistor R2 reduces the voltage and limits the current to charge the capacitor C2. In the initial period, when the capacitor C2 is not fully charged (when the length of the cable wound by the drum is not enough), for example, the time is less than 120 seconds, the 6V power supply is divided by the adjustable resistor RP1 and the resistor R1, and the resistor R2 reduces the voltage and limits the current to enter the base of the transistor Q1 below 0.7V, and the transistor Q1 will not be turned on, so the relay K2 continues to lose power, and the main power input end of the electric drive winding drum body (DJ) 1 continues to be powered and the cable is wound. After charging for a period of time, when capacitor C2 is fully charged (the length of the cable to be wound up by the drum reaches the required length), for example, the time reaches 120 seconds, the 6V power supply is divided by the adjustable resistor RP1 and the resistor R1, and the resistor R2 steps down and limits the current to enter the base of the transistor Q1, which is higher than 0.7V. The transistor Q1 will conduct the collector output low level and enter the negative power input terminal of the relay K1. The relay K1 is energized to close its control power input terminal and the normally open contact terminal. Subsequently, the buzzer B1 is energized to sound to remind the on-site staff that the length of the drum winding cable 7 is sufficient, the relay K2 is energized to close its control power input terminal and the normally closed contact terminal, the main power input terminal of the electric drive winding reel body 1 loses power, and the cable is no longer wound up. The wireless receiving circuit module W3 is energized to work and transmit the first wireless closing signal (the two contacts under the first transmitting button S1 are connected together). After the staff who are not on site carry the reminder circuit wireless receiving circuit module W4 with them, it receives the first wireless closing signal, and its 3-pin outputs a high level which enters the positive power input terminal of the buzzer B1. Then, the buzzer B1 is energized and sounds to remind the staff that the length of the drum winding cable is sufficient and they can arrive at the site for timely processing.

[0019] Figure 1 , 2 As shown in Figure 3, through the above, the new type can automatically count the length data of the drum winding cable by timing, and can immediately disconnect the main power supply after the length is sufficient, and alarm the staff on site through the buzzer and wirelessly remind the staff, thus preventing the drum winding cable from being too long, bringing convenience to the staff and correspondingly improving work efficiency. Figure 2 ,3 Among them, relays K1 and K2 are DC 12V relays; transistor Q1 is a NPN transistor of model 9013; power module W1 is a finished product of AC 220V to DC 12V switching power module; battery G1 is a 12V / 10Ah lithium battery; resistors R1 and R2 have resistance values ​​of 410K and 70K respectively; capacitors C1 and C2 are electrolytic capacitors of 470μF / 25V and 100μF / 25V respectively; wireless transmitting circuit module W3 and wireless receiving circuit module W4 are finished products of wireless transmitting and receiving circuit module components of model WF500, and the wireless signal receiving and sending distance is 500 meters (consistent with the principle of automotive wireless remote control components); buzzer B1 is a finished product of active continuous sound buzzer alarm of model FM12V; sounder B is a finished product of model The finished product of XQ12V active continuous sound alarm; the model of bridge pile W2 is KBP301; the generator M is a small 6V AC generator; the resistance value of the adjustable resistor RP1 is 8M (in this embodiment, it is adjusted to about 1.1M. Specifically, when the staff adjusts the resistance value to a larger value, the voltage division between it and the resistor R1 is larger, the charging time of the capacitor C2 is longer, the conduction time of the transistor Q1 is extended, and the length of the cable wound by the drum will become longer. When the staff adjusts the resistance value to a smaller value, the voltage division between it and the resistor R1 is smaller, the charging time of the capacitor C2 is faster, the conduction time of the transistor Q1 is shortened, and the length of the cable wound by the drum will become shorter. The actual production staff adjusts the cable winding length of the drum according to the number on the side of the adjustable resistor handle).
