Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a sliver guide frame of a combing lap machine for cleaning cotton sliver short fluff. Background Art

[0002] The combing lap machine is an integral part of the combing preparation process in the textile industry. It is mainly used to combine and stretch the pre-combined slivers and improve the parallelism of the fibers to reduce the combing burden and improve the combing output and quality. The slivers are pulled by the guide frame and fed into the cotton guide platform, which can effectively prevent the irregular arrangement of the slivers. Since the slivers contain some short fibers and some flying fibers are attached during processing, a scraper is set at the guide frame in the prior art, such as the FA1398 lap machine, and the scraper is used to scrape off the short fibers and flying fibers to improve the yarn quality.

[0003] However, for this structure, since the scraper is made of plastic and fixed to the guide frame, it is easy to accumulate frequently at the scraper due to the influence of temperature and humidity, and the lint of the cotton sliver. After accumulation, a large number of defects will enter the next process with the cotton sliver, affecting the quality of the yarn. Therefore, it is necessary for the lathe operator to clean it frequently, which not only increases the workload, but also has the problem of inconvenience in cleaning due to the obstruction of the scraper, especially there will be residues between the scraper and the cotton sliver. For example, patent CN201721753082.2 discloses a cleaning device for the cotton guide roller of a combing machine, which scrapes off cotton wax and lint through a scraper, drops them on a cleaning tray, and then cleans them. Utility Model Content

[0004] The utility model aims to provide a sliver guide frame for a combing lap machine for cleaning short lint in cotton slivers in view of the deficiencies of the prior art. The sliver guide frame has a simple structure, can effectively clean short lint and flying flowers, has a good cleaning effect, and is easy to maintain.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a combing sliver roll machine guide frame for cleaning short lint of cotton slivers, which includes a frame, two sliver guide rollers, and at least two lint rollers. The sliver guide rollers are respectively arranged at the two ends of the frame, and the lint roller is located between the two sliver guide rollers and arranged in parallel with the sliver guide rollers. The frame is provided with a plurality of grooves, and bearings and bearing supports are provided at both ends of the lint roller. The lint roller is movably connected with the groove of the frame through the bearing support. The cotton slivers pass through the guide frame respectively under the guidance of the two sliver guide rollers. The lint roller is located above the cotton slivers and a small gap is reserved. The lint roller has no external power. The cotton slivers will hit the lint roller during the traction process, driving the lint roller to rotate. While the lint roller rotates, the short lint and flying flowers on the cotton slivers can be wound around the lint roller, thereby separating them from the cotton slivers. Compared with the situation that the scraper scrapes off the short lint, the short lint accumulates at the location where the accumulation space is limited, which requires frequent cleaning, the technical solution winds the short lint on the lint roller, which greatly saves space and significantly reduces the frequency of cleaning. When cleaning the short lint, the lint roller can be quickly and conveniently removed, and then a new lint roller can be put down.

[0006] Preferably, the circumferential surface of the lint roller is provided with fine cotton lint to increase the adsorption capacity for short lint.

[0007] Preferably, the number of the velvet rollers is three, and the distance between adjacent velvet rollers is greater than 3 cm, so that the velvet rollers can be easily removed by hand.

[0008] Preferably, the frame is provided with 3-5 groups of grooves, each group of grooves corresponds to a bearing support at both ends of a velvet roller, the velvet roller can be placed in a suitable position as needed, and grooves of different depths can be set. When the short velvet wound on the velvet roller has a certain thickness, it can be transferred to a shallower groove for continued use to avoid excessive pressure between the velvet roller and the cotton strip. The velvet roller is connected to the velvet roller support through a bearing, and the velvet roller can rotate flexibly.

[0009] The groove is located on the upper side of the frame, and the velvet roller is located above the cotton strip, so it is convenient to remove and replace the velvet roller.

[0010] The beneficial effects of the utility model are: the utility model has a simple structure, can conveniently clean short lint and flying flowers, has a high cleaning efficiency, reduces the accumulation of short lint and flying flowers, improves the yarn quality, reduces the labor intensity of workers, reduces their workload, and the lint roller can be quickly removed and installed, and can be transferred to other positions to clean the short lint on the lint roller, which is easy to operate.

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0017] like Figure 1 , 2 As shown, a sliver guide frame for a combed lap machine for cleaning short lint of cotton slivers in this embodiment comprises a frame 1, two sliver guide rollers 2, and at least two lint rollers 3. Among them, the frame 1 is a metal frame, which is used to be installed and fixed on the combed lap machine. The sliver guide rollers 2 are respectively arranged at both ends of the frame, and the sliver guide rollers 2 are driven to rotate by the combed lap machine. The lint roller 3 is located between the two sliver guide rollers 2 and arranged parallel to the sliver guide rollers 2. The frame 1 is provided with a plurality of grooves. The two ends of the lint roller 3 are provided with bearings and bearing supports. The lint roller 3 is movably connected to the groove of the frame 1 through the bearing support. The cotton sliver 4 passes through the sliver guide frame respectively under the guidance of the two sliver guide rollers. The lint roller 3 is located above the cotton sliver 4. When the cotton sliver 4 is pulled, the lint roller 3 is driven to rotate. When the lint roller 3 rotates, the short lint and flying flowers on the cotton sliver 4 can be wound around the lint roller 3, thereby separating them from the cotton sliver 4.

[0018] Since the short lint is wound on the lint roller 3, the short lint will not accumulate on the surface of the sliver 4, thus preventing the short lint from entering the next process with the sliver 4 and affecting the yarn quality. Compared with the prior art, the short lint is wound more tightly and can be distributed on the entire circumference of the lint roller, which greatly increases the area for collecting the short lint and eliminates the need for frequent manual cleaning.

[0019] The groove is located on the upper side of the frame 1, and the velvet roller 3 is located above the cotton strip 4. The circumferential surface of the velvet roller 3 is provided with fine cotton fluff to increase the adsorption capacity for short fluff. There are three velvet rollers 3, and the distance between adjacent velvet rollers 3 is greater than 3 cm. The frame 1 is provided with 3-5 groups of grooves, and each group of grooves corresponds to the bearing supports at both ends of a velvet roller 3. The grooves have different depths. When in use, the velvet roller 3 can be placed in the deeper groove first. When the short fluff wrapped around the velvet roller 3 has a certain thickness, it can be transferred to the shallower groove for continued use. When the velvet roller 3 has a lot of short fluff, it can be directly removed and a new velvet roller 3 can be placed. The removed velvet roller 3 can be transferred to other locations for cleaning.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
