Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spinning production, in particular to a high-low pressure conversion structure of composite elasticizer. BACKGROUND

[0002] When a TMT-S+Z composite elasticizer produces different products on A surface and B surface, the pressure needs to be converted according to the different pressure of the products. At present, one set of pressure system is used for one composite elasticizer in production, that is, two pipes with valves are respectively drawn out from the high-pressure manifold and the low-pressure manifold, then the two pipes are connected to the inlet end of the filter bubble bottle, and then the gas is supplied to the two sides of the TMT-S+Z composite elasticizer through the three-way outlet pipe of the filter bubble bottle. When the products produced on A surface and B surface have the same pressure, the corresponding valve is opened to supply the gas to A surface and B surface at the same time, so that the products can be produced at the same time.

[0003] However, when the products with different pressures are produced, the TMT-S+Z composite elasticizer must be stopped because of the unreasonable pressure, and only one surface can be stopped, which brings inconvenience to the production, increases the labor intensity, reduces the indicators, and wastes the pressure and electricity in the energy-saving aspect. Therefore, under the premise of using one set of pressure pipe for one machine, the gas circuit needs to be improved so that the A surface and the B surface of the TMT-S+Z composite elasticizer can adjust the pressure according to different products.

[0021] like Figure 1 As shown, a high-low pressure conversion structure for a composite texturing machine includes a low-pressure main pipe 6 and a high-pressure main pipe 5 arranged in parallel, a low-pressure drain pipe 9 with a valve on one side of the low-pressure main pipe 6, a high-pressure drain pipe 10 with a valve on one side of the high-pressure main pipe 5, a first air supply pipe 1 and a second air supply pipe 21 connected to the air inlet pipes on both sides A and B of the composite texturing machine, respectively. The first air supply pipe 1 has a first filter bubble bottle 4 at its inlet end, and the second air supply pipe 21 has a second filter bubble bottle 17 at its inlet end. The low-pressure drain pipe 9 has a low-pressure airflow regulating device 8 at its outlet end, and the high-pressure drain pipe 10 has a high-pressure airflow regulating device at its outlet end. In configuration 7, the low-pressure airflow regulating device 8 and the high-pressure airflow regulating device 7 are connected in parallel. The low-pressure gas output from the low-pressure drain pipe 9 can be supplied to any one of the first filter bubble bottles 4 or the second filter bubble bottle 17 through the low-pressure airflow regulating device 8. The high-pressure gas output from the high-pressure drain pipe 10 can be supplied to any one of the first filter bubble bottles 4 or the second filter bubble bottle 17 through the high-pressure airflow regulating device 7. The first gas supply pipe 1 and the second gas supply pipe 21 can be supplied with gas separately by the low-pressure airflow regulating device 8 and the high-pressure airflow regulating device 7 simultaneously.

[0022] Compared with the original pressure system, in the improvement, the operating pipeline between the low-pressure drainage pipe 9 and the high-pressure drainage pipe 10, the first gas supply pipe 1 and the second gas supply pipe 21 is completely removed and redesigned. In actual production, the valves on the low-pressure drainage pipe 9 and the high-pressure drainage pipe 10 are generally in the open state, the low-pressure gas in the low-pressure main pipe 6 is transported to the low-pressure gas flow regulating device 8 through the low-pressure drainage pipe 9, and the two air pressure pipes of the compound elasticizer are communicated with the first gas supply pipe 1 and the second gas supply pipe 21 respectively, and the A surface and the B surface are separately supplied with air through the first gas supply pipe 1 and the second gas supply pipe 21. Among them, the low-pressure gas output by the low-pressure drainage pipe 9 can be separately supplied to the first filter bubble bottle 4 or the second filter bubble bottle 17 through the low-pressure gas flow regulating device 8, or can be simultaneously supplied; and the high-pressure gas output by the high-pressure drainage pipe 10 can be separately supplied to the first filter bubble bottle 4 or the second filter bubble bottle 17 through the high-pressure gas flow regulating device 7, or can be simultaneously supplied. For example, when the A surface needs to use low-pressure gas and the B surface needs to use high-pressure gas, the gas output by the low-pressure drainage pipe 9 is transported to the first filter bubble bottle 4 through the low-pressure gas flow regulating device 8, and then the low-pressure gas is transported into the first gas supply pipe 1 through the first filter bubble bottle 4, so as to realize the low-pressure gas supply of the A surface; and the gas output by the high-pressure drainage pipe 10 is transported to the second filter bubble bottle 17 through the high-pressure gas flow regulating device 7, and then the high-pressure gas is transported into the second gas supply pipe 21 through the second filter bubble bottle 17, so as to realize the high-pressure gas supply of the B surface; when the A surface and the B surface need to use high-pressure or low-pressure gas at the same time, the corresponding gas flow regulating device can be closed, or the corresponding valve can be controlled by cutting off, so as to realize that when a TMT-S+Z compound elasticizer produces different products on the A surface and the B surface, the A surface and the B surface can be simultaneously and separately supplied with air. When the A surface and the B surface produce products with different pressures, the switching is convenient, the flexibility is high, the machine does not need to be stopped for operation, the spinning is more convenient, the labor intensity is lower, and the problem of resource waste does not occur. Among them, the use of two filter bubble bottles can realize the separate filtration of the two surfaces of a TMT-S+Z compound elasticizer, so as to reduce the number of shutdowns and achieve better energy-saving effect.

[0023] Further improvement is that the low-pressure gas flow regulating device 8 comprises a low-pressure shunt pipe 11 in communication with the low-pressure drainage pipe 9, two low-pressure flow direction control valves 12 arranged at both ends of the low-pressure drainage pipe 9, and a low-pressure flow guide pipe 13 arranged between the gas outlets of the two low-pressure flow direction control valves 12 and the first filter bubble bottle 4 and the second filter bubble bottle 17 respectively.

[0024] When the flow direction of the gas flow is controlled by the low-pressure gas flow regulating device 8, the low-pressure gas output by the low-pressure flow guide pipe 9 can be supplied to both ends through the low-pressure shunt pipe 11, and the two low-pressure flow direction control valves 12 at both ends can be opened and cut off in a targeted manner, so that the gas flow flows to the first filtered bubble bottle 4 or the second filtered bubble bottle 17 along different low-pressure flow guide pipes 13, thereby effectively delivering the low-pressure gas flow to the required first gas supply pipe 1 or the second gas supply pipe 21 for gas supply. In operation, it is more simple and convenient, and when gas supply is not required, the two low-pressure flow direction control valves 12 can be cut off at the same time to block the gas flow, which is more flexible in operation and can effectively avoid waste of gas.

[0025] Further improvement is that the high-pressure gas flow regulating device 7 comprises a high-pressure shunt pipe 14 in communication with the high-pressure flow guide pipe 10, two high-pressure flow direction control valves 15 arranged at both ends of the high-pressure flow guide pipe 10, and high-pressure flow guide pipes 16 arranged between the gas outlets of the two high-pressure flow direction control valves 15 and the first filtered bubble bottle 4 and the second filtered bubble bottle 17, respectively.

[0026] When the flow direction of the gas flow is controlled by the high-pressure gas flow regulating device 7, the high-pressure gas output by the high-pressure flow guide pipe 10 can be supplied to both ends through the high-pressure shunt pipe 14, and the two high-pressure flow direction control valves 15 at both ends can be opened and cut off in a targeted manner, so that the gas flow flows to the first filtered bubble bottle 4 or the second filtered bubble bottle 17 along different high-pressure flow guide pipes 16, thereby effectively delivering the high-pressure gas flow to the required first gas supply pipe 1 or the second gas supply pipe 21 for gas supply. In operation, it is more simple and convenient, and when gas supply is not required, the two high-pressure flow direction control valves 15 can be cut off at the same time to block the gas flow, which is more flexible in operation and can effectively avoid waste of gas.

[0027] Further improvement is that the two adjacent low-pressure flow guide pipes 13 and high-pressure flow guide pipes 16 are connected to the corresponding first filtered bubble bottle 4 and second filtered bubble bottle 17.

[0028] Since the pipes are all made of metal pipes with a diameter of more than 10 cm, the overall weight is relatively large, and the structure is connected in series, which makes the layout of the pipes more tidy, the overall weight lighter, and the safety higher when suspended.

[0029] Further improvement is that a first shunt pipe 2 is arranged between the first gas supply pipe 1 and the gas outlet of the first filtered bubble bottle 4, and a second shunt pipe 19 is arranged between the second gas supply pipe 21 and the gas outlet of the second filtered bubble bottle 17.

[0030] The first shunt pipe 2 is connected between the first gas supply pipe 1 and the gas outlet of the first filtering bubble bottle 4, which can make the position of the first shunt pipe 2 more flexible, and can facilitate the gas supply of other devices in the later period, and is more expandable, and the second shunt pipe 19 is the same.

[0031] Further, one end of the first shunt pipe 2 and the second shunt pipe 19 are connected in series by welding, and a sealing baffle 20 is welded at the series connection position of the first shunt pipe 2 and the second shunt pipe 19; the outer end of the first shunt pipe 2 and the second shunt pipe 19 is provided with a plug 3.

[0032] When the first shunt pipe 2 and the second shunt pipe 19 are modified, the original pipe is formed by cutting, and the two are connected again by the sealing baffle 20, and the overall modification cost is lower, and the outer end of the first shunt pipe 2 and the second shunt pipe 19 is plugged by the plug 3, when it is needed to be connected with other devices or pipes again, only the plug 3 needs to be disassembled to realize the connection, which effectively improves the flexibility of the gas pressure delivery in the spinning workshop.

[0033] Further, the inlet and outlet pipes of the first filtering bubble bottle 4 and the second filtering bubble bottle 17 are provided with pressure gauges 18. The high and low gas pressures can be accurately controlled by the pressure gauges 18, so that the unstable gas pressure delivery can be avoided.

[0034] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application are within the scope of protection of the present application.
