Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of warp production and processing, in particular to a yarn outlet roller mechanism for warp sizing. Background Technique
[0002] After the warp passes through the sizing vat for secondary sizing, a yarn outlet roller must be installed to achieve the function of separating the yarns. Also, since direct contact between the warp and the yarn outlet roller will cause friction and result in sizing scraping, it is necessary to add a lubricant between the yarn outlet roller and the warp to reduce friction. Therefore, taking advantage of the characteristic that heat conducts from a high-temperature area to a low-temperature area to cause condensation, cold water is injected into the yarn outlet roller, so that the surface of the yarn outlet roller generates condensation due to the action of the external high temperature and acts as a lubricant.
[0003] When the machine stops, the condensed water generated on the surface of the yarn outlet roller cannot be used up in time. Excessive condensed water soaking the warp will cause a reduction in sizing and single fiber breakage of the warp, resulting in quality defects. Content of the Utility Model
[0004] To solve the technical problems in the background technique, the utility model proposes a yarn outlet roller mechanism for warp sizing.
[0005] The yarn outlet roller mechanism for warp sizing proposed by the utility model includes a yarn outlet roller, a water tank, a negative pressure tank, and a valve. A condensation channel is coaxially opened in the yarn outlet roller along its length direction. One end of the yarn outlet roller is connected with a water inlet pipe through a first rotary joint, and the other end is coaxially connected with a water outlet pipe through a second rotary joint. Both the water inlet pipe and the water outlet pipe are communicated with the condensation channel. The first inlet of the valve is fixedly communicated with the water tank through a water pump, the second inlet is fixedly communicated with the negative pressure tank, and the first outlet is fixedly communicated with the water inlet pipe, so that the water inlet pipe is communicated with the water tank or the negative pressure tank through the valve.
[0006] Preferably, the valve is specifically a three-way solenoid valve. When the coil of the three-way solenoid valve is energized, the first inlet is opened and the second inlet is closed. When the coil of the three-way solenoid valve is de-energized, the first inlet is closed and the second inlet is opened.
[0007] Preferably, the outlet end of the water outlet pipe is communicated with the water return port on the water tank.
[0008] Preferably, the water return port on the water tank is located above the water surface in the water tank.
[0009] Preferably, a pressure relief valve is also opened at the top of the water tank.
[0010] Preferably, the number of yarn outlet rollers is multiple, and the multiple yarn outlet rollers are arranged in parallel.
[0011] Preferably, the water inlet pipe includes a main pipe and multiple branch pipes all communicated with the main pipe. The inlet end of the main pipe is communicated with the first outlet on the valve, and the outlets of the multiple branch pipes are respectively communicated with the condensation channels of the multiple yarn outlet rollers through the first rotary joints.
[0012] For the yarn delivery roller mechanism proposed by the present utility model, when the machine stops, the first inlet on the valve closes, and the second inlet opens. The condensation channel in the yarn delivery roller communicates with the negative pressure tank, thereby quickly draining the cooling water in the condensation channel, thus avoiding the continuous generation of dew. The dew on the yarn delivery roller soaking the warp yarn will cause a decrease in sizing, and the single fiber breakage of the warp yarn will cause quality defects. Brief Description of the Drawings
[0013] Figure 1 It is a schematic structural diagram of a yarn delivery roller mechanism for warp sizing proposed by the present utility model. Detailed Embodiment
[0014] Referring to Figure 1 , a yarn delivery roller mechanism for warp sizing proposed by the present utility model includes a yarn delivery roller 1, a water tank 2, a negative pressure tank 3, and a valve 4. A condensation channel penetrating along its length direction is coaxially provided in the yarn delivery roller 1. One end of the yarn delivery roller 1 is connected with a water inlet pipe 7 through a first rotary joint, and the other end is coaxially connected with a water outlet pipe 5 through a second rotary joint. Both the water inlet pipe 7 and the water outlet pipe 5 communicate with the condensation channel. The first inlet on the valve 4 is fixedly communicated with the water tank 2 through a water pump, the second inlet is fixedly communicated with the negative pressure tank 3, and the first outlet is fixedly communicated with the water inlet pipe 7, so that the water inlet pipe 7 communicates with the water tank 2 or the negative pressure tank 3 through the valve 4.
[0015] Specifically, when the machine is in normal use, the first inlet opens, and the second inlet closes. The external driving mechanism drives the yarn delivery roller 1 to rotate for yarn delivery. The cooling water in the water tank 2 enters the condensation channel on the yarn delivery roller 1 through the first inlet on the valve 4 and the water inlet pipe 7 under the drive of the water pump, cools the yarn delivery roller 1 to cause dew on the yarn delivery roller 1 for lubrication. When the machine stops, the second inlet opens, and the first inlet closes. At this time, the cooling water remaining in the condensation channel continues to flow towards the water outlet pipe 5 under the negative pressure in the negative pressure tank 3 until the cooling water in the condensation channel is completely discharged, avoiding the problem that when the machine is in the stopped state, the cooling water remaining in the condensation channel causes a large amount of dew on the yarn delivery roller 1, and the large amount of dew soaking the warp yarn causes a decrease in sizing and the single fiber breakage of the warp yarn causes quality defects.
[0016] In the above embodiment, the valve 4 can be a manual valve. When the machine stops, the first inlet is closed, and the second inlet is opened to make the condensation channel communicate with the negative pressure tank 3 for drainage. However, the manual valve is relatively troublesome and cannot be switched in time when the machine stops. Therefore, to improve the automation performance of this mechanism during use, the valve 4 in the present utility model is specifically a three-way solenoid valve. When the coil of the three-way solenoid valve is energized, the first inlet opens, and the second inlet closes. When the coil of the three-way solenoid valve is de-energized, the first inlet closes, and the second inlet opens.
[0017] It should be further noted that the outlet end of the water outlet pipe 5 is connected to the water return port on the water tank 2, which is convenient for recycling the cooling water. When the machine is working, the water inlet pipe 7, the condensation channel, the water outlet pipe 5, and the water tank 2 together form a circulation loop, so that the cooling water can continuously pass through the condensation channel to cool the yarn outlet roller 1.
[0018] In the above embodiment, the water return port on the water tank 2 is located above the water surface in the water tank 2.
[0019] To avoid excessive pressure in the water tank 2, a pressure relief valve 6 is also provided at the top of the water tank 2.
[0020] It should be further noted that there are multiple yarn outlet rollers 1 in the yarn outlet roller mechanism on the existing sizing machine, and the multiple yarn outlet rollers 1 are arranged in parallel to achieve the purpose of yarn separation. In the above embodiment, each yarn outlet roller 1 can be respectively connected with a valve 4 through the water inlet pipe 7. However, if set in this way, the production cost of the mechanism will be increased. To reduce the cost on the basis of multiple yarn outlet rollers 1, in this new type, the water inlet pipe 7 includes a main pipe 71 and multiple branch pipes 72 all communicating with the main pipe 71. The inlet end of the main pipe 71 is connected to the first outlet on the valve 4, and the outlets of the multiple branch pipes 72 are respectively connected to the condensation channels of the multiple yarn outlet rollers 1 through the first rotary joints. The condensation channels in the multiple yarn outlet rollers 1 are connected to the water tank 2 or the negative pressure tank 3 through the same water inlet pipe 7 and valve 4, so that the setting of the mechanism is simpler and its production cost is reduced.
[0021] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
