Description
Technical Field
The invention relates to the technical field of cable processing, in particular to a full-automatic quantitative spacer smearing device and a control method thereof in the production process of a silicone rubber cable.
Background
The wire and cable is simply called a cable, and is a wire product for transmitting electric (magnetic) energy, information and realizing electromagnetic conversion. Several cables need to be attached with talcum powder in the production process, such as silicone rubber cables, and because the silicone rubber is relatively sticky, talcum powder is required to be attached to the surfaces of the cables before winding and packaging to serve as an isolating substance, so that an isolating effect is achieved between the cables, and the cables are prevented from being sticky to each other. In all the processes of attaching the isolating material, the isolating layer is required to be continuous and uniform.
At present, the commonly used isolating materials are powdered talcum powder and liquid isolating agent. The existing isolating material has the following problems in the actual processing process:
1. the powdery talcum powder has the problem of air environment pollution, and has higher requirements on dust explosion-proof grade of a production workshop;
2. although the traditional liquid isolating agent has no talcum powder, the smearing process is greatly influenced by the change of the cable conveying speed and the change of the wire diameter in the production process, and the problems of uneven smearing, excessive smearing or insufficient smearing easily occur, namely the using amount of the isolating agent cannot be accurately controlled, and the using amount of the isolating agent is large.
Therefore, how to solve the above-mentioned drawbacks of the prior art is a subject to be studied and solved by the present invention.

The control unit 19 may be a PC, a PLC, or the like.
The control unit 19 collects the cable speed signal and the outer diameter signal, and sends control signals to the constant displacement pump 11, the proportional throttle valve 13 and the drying processing unit 3 through automatic operation in combination with the set parameters. When the speed and the outer diameter are increased, the interval time between two starts is reduced by the constant displacement pump 11 under the control of the control unit 19, the opening degree of the proportional throttle valve 13 is increased under the control of the control unit 19, the dropping speed of the isolating agent is increased, and the drying power is increased by the drying processing unit 3; conversely, when the speed and the outer diameter are reduced, the fixed displacement pump 11 increases the interval time between two starts, the proportional throttle 13 decreases the opening degree, and the drying processing unit 3 decreases the drying power.
The quantitative supply unit 2 quantitatively supplies the isolating agent to the smearing unit 1, the quantitative pump 11 intermittently extracts the quantitative isolating agent from the storage tank 10, that is, automatically stops when the accumulated extraction flow reaches a set value after each start, starts after waiting for the control unit 19 to send a start signal again, and automatically stops again when the accumulated flow reaches the set value, and the circulation is performed. The starting signal of the control unit 19 is obtained from the fixed displacement pump 11 and then started until the next time, which is called a "fixed displacement pump start cycle".
The flow rate of the release agent is determined not only by the fixed displacement pump 11 but also by the opening of the proportional throttle 13, and the release agent flows into the applying unit 1 by its own weight. During a start-up period of the dosing pump 11, the isolating agent in the intermediate buffer tank 12 may be required to flow all the way through the proportional throttle valve 13 into the application unit 1, i.e. the intermediate buffer tank 12 may be in a emptied state before the dosing pump 11 is started again.
The control method of the full-automatic release agent quantitative smearing device is now described as follows:
the control method comprises the following steps:
step one, preparing work; adding a sufficient amount of a release agent to the tank 10 of the dosing unit 2; adding a release agent into the coating inner core 8 of the coating unit 1 to ensure that the release agent is attached to the surface of the cable 6 at the beginning; the cable 6 is put into the smearing unit 1, the smearing inner core 8 is stuck and wrapped on the surface of the cable 6, and then the cable 6 is pulled and passes through the speed measuring unit 4 and the wire diameter measuring unit 5.
At this time, since the cable 6 is still in a stationary state, the cable speed signal v=0 detected by the speed measuring unit 4, and the opening degree signal c=v×d×k1×δ=0 of the proportional throttle 13;
when meeting the requirementsAnd f (T) =v×d×t×δ, the fixed displacement pump is started, and at this time, the start cycle T of the fixed displacement pump is= infinity;
the heating and drying unit 3 is stopped because of the power level signal w=v×d×k2×δ=0; wherein:
t is time;
v is the cable speed signal detected by the speed measuring unit;
d is the cable outer diameter signal detected by the wire diameter unit;
delta is a thickness parameter of a coating 9 on the surface of the cable 6, which needs to be attached with a release agent, and can be set according to process requirements before working;
v is the single supply quantity of the quantitative pump, and the value is a fixed set value which can be manually set according to the process requirement;
k1 and k2 are debugging coefficients, and are set during equipment debugging;
step two, starting work; at this time, the cable speed signal v detected by the speed measuring unit 4 is more than 0, and the cable outer diameter signal d detected by the wire measuring unit 5 is more than 0; after receiving the cable speed signal v detected by the speed measuring unit 4 and the cable outer diameter signal d detected by the wire diameter unit 5, the control unit 19 calculates a start period T of the fixed displacement pump 11, an opening degree signal C of the proportional throttle valve 13, and a power level signal W of the heating and drying unit 3 according to the calculation method in the first step, and then outputs control signals to the fixed displacement pump 11, the proportional throttle valve 13, and the heating and drying unit 3, respectively.
The quantitative pump 11 starts to run after obtaining signals, and the isolating agent in the storage tank 10 is sent into the middle buffer tank 12 through the discharging pipeline 14; the proportional throttle valve 13 is opened corresponding to the opening degree after receiving the signal, and the isolating agent flows into the coating inner core 8 of the coating unit 1 from the intermediate buffer tank 12 through the feed pipeline 15 by gravity through the proportional throttle valve 13 and is coated on the surface of the cable 6 to form the isolating agent coating 9;
the liquid isolating agent attached to the surface of the cable 6 is heated and solidified by the heating and drying unit 3, the power W of the heating and drying unit 3 is directly related to the product of the speed v of the cable and the wire diameter d, and the power W is dynamically and automatically adjusted.
Step three, in the process of smearing the release agent, when meeting the following conditionsAnd f (t) =v×d×t×δ, the fixed displacement pump is started again and re-clocked (tball).
Wherein the flow rate of the isolating agent instantaneously conveyed by the constant displacement pump 11 is larger than that of the isolating agent passing through the proportional throttle valve 13; the constant delivery pump 11 is automatically stopped after the accumulated flow reaches a set amount, and the intermediate buffer tank 12 temporarily stores the redundant isolating agent and slowly releases the isolating agent to the smearing unit 1 under the action of gravity, and can completely release the isolating agent before the constant delivery pump 11 is started next time; the opening of the proportional throttle valve 13 is positively correlated with the product of the speed and the wire diameter of the cable 6, and is dynamically and automatically adjusted.
By means of the design, the starting period of the constant displacement pump 11 and the opening degree of the proportional throttle valve 13 can be controlled in real time according to the transmission speed and the line diameter change data of the cable 6, the total supply of the isolating agent can be regulated through the secondary control of the supply quantity of the isolating agent, the accurate supply of the using quantity of the isolating agent can be realized, the total quantity of the isolating agent is greatly reduced, and a large amount of related cost is saved for a producer.
