Description

Glue spreading extrusion device

Technical Field

The utility model relates to the field of tire production equipment, in particular to a gluing extrusion device.

Background

In the manufacturing process of the tire, the rubber-coated steel wire is conveyed to the machine head of the extruder after being led out from the spindle stock roll, tension controlled and preheated, the extruder extrudes rubber materials through a screw rod to reach a steel wire passing area, and when the steel wire leaves the machine head of the extruder, a layer of rubber is coated on the surface of the steel wire and enters a downstream ring section for material storage and drum surface winding.

The production process of the rubberized steel wire is generally a high-speed, high-pressure and high-temperature working condition environment, and the working procedures from upstream to downstream are generally continuous production, and once a certain link fails to cause shutdown, the production efficiency and the product quality of the whole wire can be affected. The extrusion gluing link frequently fails due to the influences of various factors such as steel wire tension, steel wire connectors, temperature, feeding fluctuation, leakage, head pressure fluctuation and the like, and if the quick response and automatic adjustment are met in the gluing link, the production efficiency and the product quality stability are greatly improved.

As a process of pressure coating by extrusion, the coating amount on the surface of the steel wire and the extrusion conveying amount have large deviation, namely, a high supply amount and a low demand amount, and if the excessive material conveyed to the coating machine head stays in the machine head for a long time and cannot be discharged along with the steel wire or other paths, the material performance change, such as local scorching or blocking of a mouth-shaped channel, is necessarily caused in a cavity with difficult high-temperature and high-pressure flow, so that the coating quality is affected.

In addition, the surface of the steel wire is coated with the adhesive at a high linear speed, and the thickness and the uniformity of the coating are also indicators of high attention of users, such as common copper leakage defects or uneven thickness defects on the surface of the steel wire, so that the problems of raw material steel wires and sizing materials are eliminated, and the adhesive is generally greatly related to the internal material pressure, temperature control and speed control of a gluing machine head. How to make up pressure under low pressure and how to release pressure under high pressure, the pressure and the temperature in a material pool of a steel wire gluing area are always kept uniform and stable, and a good solution is lacking in the industry.

The current gluing extrusion devices used in the industry have shortcomings in solving the problems, and the gluing process generally depends on manual adjustment and lacks feedback control. For example, patent CN 114013007B discloses a solution for improving coating uniformity of a steel wire coating extruder head assembly, but the mounting and opening and closing operations of the extruder head are manual, and the adjustment control of the extruder head can only be manually selected to be opened or closed, and the control is too dependent on the feedback of signals of manual work or other links downstream, so that the problem of coating fluctuation cannot be automatically responded, which is insufficient for long-time stable control of coating under continuous production.

Therefore, the prior art has the problem of poor usability of the gumming extrusion device.

When the glue extrusion apparatus of the present utility model is used, the first and second heads 10 and 40 can communicate through the locking ring 30. When the machine is installed, the locking ring 30 is firstly adjusted to the yielding position, after the second machine head 40 is aligned with the first machine head 10, the first flow channel 11 of the first machine head 10 and the second flow channel 41 of the second machine head 40 can be kept in a communicated state by switching the locking ring 30 from the yielding position to the limiting position, meanwhile, the second machine head 40 is in a locking state, and at the moment, sizing material can enter the first flow channel 11 from the machine barrel 20 and be coated on the surface of a steel wire after entering the second flow channel 41 through the first flow channel 11. And at this time the locking ring 30 is in the limit position, the second handpiece 40 cannot be switched from the locked state to the unlocked state. When the second runner in the second machine head needs to be replaced, the locking ring 30 can be adjusted in position, so that the locking ring 30 rotates relative to the first machine head 10 and the second machine head 40 and is switched from the limiting position to the yielding position, and then the second machine head 40 communicated with the first machine head 10 is switched from the locking state to the unlocking state, at the moment, the second machine head can move relative to the first machine head, and operations of replacing the second runner, the shaping block, the pore plate and the like can be performed. Thus, the opening and closing operation between the first and second handpieces 10 and 40 can be achieved by the operation of the locking ring 30 in the present utility model. Therefore, the gluing extrusion device effectively solves the problem of poor service performance of the gluing extrusion device in the prior art.

At this time, the end of the second head 40 adjacent to the first head 10 cannot be withdrawn from the locking ring 30 due to the restraining interaction between the first wedge block 311 and the second wedge block 421, so the second head 40 is in the locked state at this time. Or the second wedge 421 on the second handpiece 40 is now blocked by the corresponding first wedge 311. In the present utility model, on the other hand, the locking ring 30 is rotated, so that the first wedge block 311 of the locking ring 30 is blocked on the movement path of the second wedge block 421 when the second handpiece 40 withdraws from the locking ring 30, and thus the locking between the first wedge block 311 and the second wedge block 421 is achieved. Preferably, in order to ensure easier rotation of the locking ring 30, the side of the first wedge block 311 where it contacts the second wedge block 421 and the side of the first and second handpieces 10 and 40 where it contacts each other are not parallel to each other, but have an included angle of more than 0 degrees.

In one embodiment of the present utility model, when the second handpiece 40 is locked: the second handpiece 40 with the second flow channel 41, the orifice plate, the shaping block and the positioning pressure release mechanism 80 is close to the first handpiece 10 by taking the rotation axis of the locking ring 30 as the center, and the axes are coincident, at this time, the first wedge teeth of the locking ring 30 and the second wedge teeth of the second handpiece 40 are staggered in a concave-convex manner, and the position detection assembly 70 can detect the angle position of the locking ring 30, so that the first handpiece 10 and the second handpiece 40 are in a loose state.

In the present utility model, when the second flow path 41 is replaced, the second handpiece 40 may be replaced with a part having the second flow path 41.

When the sizing material reaches the machine head, the sizing material sequentially passes through the first pressure temperature detection assembly 82, the first flow channel 11, the gluing area and the second pressure temperature detection assembly 83 and enters the pressure release channel 43, and under the condition that the whole linear speed does not need to be changed, the optimal coating state of the rubber material in the gluing area is always maintained by ensuring the stability of the pressure difference delta P between the second pressure temperature detection assembly 83 and the first pressure temperature detection assembly 82. When the pressure difference Δp exceeds the recipe control range, the pressure release mechanism 80 adjusts the position of the pressure release valve shaft, that is, adjusts the position of the pressure release shaft body, discharges materials from the pressure release channel 43 and monitors Δp in real time, and resumes the working position of the pressure release valve shaft after reaching the recipe control range. For some user specific process requirements, such as specific materials, not allowing for long residence times within the handpiece, this configuration may allow the pressure relief channel 43 to be normally open.

In addition, the first pressure temperature detection component 82 and the first pressure temperature detection component 82 can detect the material temperature in real time, and alarm when the temperature is abnormal, and at the moment, whether the temperature is reduced through pressure relief or speed reduction can be judged by combining pressure data so as to ensure the rheological property of the sizing material.
