Description
Technical Field
[0001] The utility model relates to the technical field of shuttle looms, in particular to a weft oil replenishing device for shuttle looms. Background Art
[0002] During the weft yarn delivery during the weft delivery during the weft production, due to the high speed of the shuttle loom (up to 1500 rpm), the weft yarn delivery speed is also positively correlated. The weft yarn delivered at high speed passes through the porcelain eye, the tension regulator, the weft delivery conveyor belt, the slingshot compensation part, the weft hook and other links, which will aggravate the wear and tear of the single weft yarn fiber, resulting in the production of fabric belt surface with fuzzing or lock edge fuzzing and other quality abnormalities. For such situations, the current practice is to rewind the yarn on the winding machine and oil the weft yarn again to increase the oil content of the yarn, thereby inhibiting the wear of the weft yarn during the delivery process and improving the fuzzing phenomenon. The disadvantage is that the time efficiency is not enough, the production machine will have downtime waiting time, affecting production efficiency and increasing the production pressure and energy consumption of the winding machine. Utility Model Content

[0024] like Figure 1 As shown, a weft oil replenishing device for a shuttle loom includes a fixing seat 4 and an oil storage assembly, the oil storage assembly is mounted on the fixing seat 4, the fixing seat 4 is connected to the shuttle loom, a pressure rod 5 is arranged in the oil storage assembly, a porcelain eye 1 is arranged on the side wall of the oil storage assembly, the oil storage assembly contains winding oil, the upper limit oil level of the winding oil is lower than the porcelain eye 1, the pressure rod 5 is located below the upper limit oil level of the winding oil, the weft yarn passes through the porcelain eye and passes under the pressure rod and then is led out from the oil storage assembly, so that the weft yarn is immersed in the winding oil in the oil storage assembly. The porcelain eye is a through hole for the weft yarn to pass through.
[0025] The oil storage assembly is a PVC pipe 3, an opening 9 is provided on the upper side of the PVC pipe 3, both ends of the PVC pipe 3 are closed, and both ends of the pressure rod 5 are respectively connected to the two ends of the PVC pipe 3. The opening 9 is formed by cutting off a part of the side wall of the PVC pipe 3, and the coning oil can be directly added to the inside through the opening. The PVC pipe is a common material, and in particular, the remaining material after cutting can be used, and the specific length can be flexibly set.
[0026] The PVC pipe 3 is filled with a sponge 6, and the coning oil permeates the sponge 6. The pressure rod 5 presses the upper sponge 6. The sponge 6 fills the internal cavity of the PVC pipe, and the sponge absorbs the coning oil. Moreover, the sponge will not cause the coning oil in the PVC pipe to shake easily, or the coning oil will not splash when foreign matter falls into the pipe, which is safer and more reliable to use. The pressure rod presses the uppermost sponge. When the weft yarn enters the PVC pipe from the porcelain eye, it bypasses from the bottom of the pressure rod, so that the weft yarn will always contact the sponge during the transportation process and adhere to the coning oil on the sponge, so that there is no need to stop the machine for oiling, which can ensure the continuity of production and improve production efficiency.
[0027] Ceramic eyes 1 are symmetrically arranged at the same height on both sides of the opening of the PVC pipe 3, that is, the weft yarn 2 enters the inside from one side of the PVC pipe and then passes through the other side to be led to other processes. Several ceramic eyes are arranged at intervals along the axial direction of the PVC pipe, and multiple weft yarns can pass through at the same time.
[0028] End caps 8 are respectively installed at both ends of the PVC pipe 3, and the pressure rod 5 is connected to the end caps 8. The end caps 8 can be directly fastened to ensure airtightness. A sealing gasket can be placed in the end cap 8 first, or the end cap and the PVC pipe can be fastened by hot melt adhesive to improve the sealing and ensure that the winding oil in the PVC pipe will not leak out from the end cap.
[0029] The end cover 8 is provided with a nut 7 with an internal thread, and the end of the pressure rod 5 is provided with an external thread, and the end of the pressure rod 5 is locked and connected with the nut 7 on the end cover 8. The nut 7 protrudes outward on the end cover 8. The threaded connection is convenient for installation and disassembly.
[0030] The middle of the PVC pipe 3 is provided with a closed section, and both sides of the closed section are openings 9. The fixing seat 4 is fixedly installed with the closed section, and the closed section is the side wall of the PVC pipe. That is, when cutting the opening, a section in the middle of the PVC pipe is left uncut to facilitate the installation of the fixing seat.
[0031] The fixing seat 4 includes a fixing plate 41 and an arc-shaped cavity 42 arranged on the fixing plate. The lower side of the PVC pipe 3 is clamped in the arc-shaped cavity 42, and the assembly is more stable.
[0032] The fixing plate 41 of the fixing seat 4 is locked and installed with the shuttle loom by means of bolts.
[0033] During the specific assembly, one end of the pressure rod can be screwed and installed with the end cover first, and then the pressure rod can be extended from one end of the PVC pipe, and then screwed with the end cover at the other end of the PVC pipe, and the end cover and the PVC pipe can be fastened and installed. First, place the sponge in the PVC pipe, and then pour the winding oil to make the sponge fully absorb the winding oil. The filling amount of the sponge needs to ensure that the pressure rod can press down the sponge. Since the height of the porcelain eye is higher than the pressure rod, the introduced weft yarn needs to go around under the pressure rod. The sponge in the pipe has a certain oil storage capacity and siphon effect. The weft yarn is always in contact with the sponge when passing through, which increases the oil content. In actual production use, the process time of rewinding and refueling the winder is reduced, which avoids the long-term downtime waiting time of the machine and improves the production efficiency of the shuttle loom; at the same time, it reduces the backlog of production tasks and energy consumption of the winder; its main purpose is to ensure the quality of the ribbon products and improve and optimize the product quality qualification rate.
[0034] For example, the task is: the specification of the weft yarn is 75D, the material is 100KG / 100 pieces, and the winding machine is refueled and rewound. The weft yarn is 1KG*9000m*1000 / 75D=120000m (i.e. 100KG / 100 pieces / 120000m each), the refueling winding machine (machine speed) is 600m / per minute, 120000m / 600m (per minute) / 60 (minutes)=3.33H (i.e.: it takes 3.33H to rewind and refuel each head once), and it is calculated based on 20 spindles on the winding machine at the same time: 3.33H*(100 heads / 20)=16.6H is required to complete.
[0035] The winding time and the waiting time of the shuttle loom can be saved. The winding time of 16.6 hours is only the pure time of the weft yarn running on the winding machine, excluding the time of 5 times of tube loading and bobbin dropping and the time of abnormal handling. The actual operation will be more than 16.6 hours. The waiting time of the ribbon machine is the same as above.
[0036] Energy saving: One spindle of the winding machine is 260W, and the power consumption is 0.26 kWh*20 spindles*16.6H=86.3 kWh of electricity required.
[0037] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
