Description

Technical Field

[0001] The utility model belongs to the technical field of ring spinning production, and in particular relates to a cleaning device for a ring compact spinning machine. Background Art

[0002] Compact spinning is a new spinning technology that is carried out on an improved new ring spinning frame. Its spinning mechanism is mainly to add a fiber coagulation zone in front of the traction device of the ring spinning frame, which basically eliminates the spinning twisting triangle between the front roller and the twisting point. When twisting high-count linen yarn into high-count linen yarn, it needs to be completed by compact spinning. While compact spinning is in operation, a large amount of short lint, cotton neps and fiber flocs will be generated. In order to avoid static electricity and fire when the spinning machine is working, a large amount of short lint, cotton neps and fiber flocs need to be cleaned by a cleaning device.

[0003] The Chinese patent network CN217616496U discloses a cleaning device for ring spinning technology textiles, comprising: a spinning machine body and a gantry, wherein the spinning machine body is arranged at the center position inside the spinning machine body, an electric telescopic rod is connected to the gantry, a dust removal mechanism is arranged on the gantry, and a cleaning machine is arranged on the gantry.

[0004] When the air outlet pipe blows the short lint, cotton knots and fiber flocs on the spinning machine body, since the two sides of the gantry are not blocked, the blown short lint, cotton knots and fiber flocs are easily dropped to the outside of the gantry. At this time, it is not easy for the suction pump to absorb the short lint, cotton knots and fiber flocs that float to the outside of the gantry. The above phenomenon makes the cleaning device ineffective in cleaning the short lint, cotton knots and fiber flocs on the spinning machine body.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0028] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1-Figure 6 As shown, the utility model is a cleaning device for a ring compact spinning machine, comprising a mounting plate 1, a first shielding cover 2 and a second shielding cover 3 are movably connected to the front of the mounting plate 1, a spinning assembly 4 is fixedly installed to the front of the mounting plate 1, a driving groove 5 is opened on the front of the mounting plate 1, a driving assembly 6 is arranged inside the driving groove 5, a driving end of the driving assembly 6 is fixedly connected to the first shielding cover 2 and the second shielding cover 3, a blowing assembly 7 is arranged inside the first shielding cover 2, a gathering assembly 8 is arranged on one side of the second shielding cover 3, and a collecting assembly 9 is arranged at the bottom of the gathering assembly 8.

[0031] The driving component 6 can drive the first shielding cover 2 and the second shielding cover 3 and make the two shielding covers close together. The closed first shielding cover 2 and the second shielding cover 3 can provide all-round shielding for the spinning component 4. At this time, the blowing component 7 on the first shielding cover 2 can blow the short fluff, cotton knots and fiber flocs on the spinning component 4. The blown short fluff, cotton knots and fiber flocs float to the inside of the gathering component 8 under the guidance of the two shielding covers. At the same time, the airflow can flow out from the inside of the gathering component 8, and the short fluff, cotton knots and fiber flocs in the gathering component 8 fall into the inside of the collecting component 9.

[0032] Through the driving component 6, the first shielding cover 2 and the second shielding cover 3 can be closed together and cover the spinning component 4 in all directions, so that when the blowing component 7 blows the short fluff, cotton knots and fiber flocs on the spinning component 4, the first shielding cover 2 and the second shielding cover 3 can guide the floating short fluff, cotton knots and fiber flocs and make them float directly to the inside of the gathering component 8, and then the collecting component 9 collects the short fluff, cotton knots and fiber flocs inside the gathering component 8. The above-mentioned arrangement enables the collecting component 9 to collect all the short fluff, cotton knots and fiber flocs blown down from the spinning component 4 under the shielding and guidance of the first shielding cover 2 and the second shielding cover 3, thereby improving the overall cleaning effect of the cleaning device.

[0033] In one embodiment, for the above-mentioned spinning component 4, the spinning component 4 includes a connecting plate 401, a connecting column 402 is fixedly connected to the front side of the connecting plate 401, one end of the connecting column 402 is fixedly connected to the spinning machine body 403, and a baffle plate 404 is fixedly connected to the front side of the connecting plate 401. Two baffle plates 404 are symmetrically arranged on the upper and lower sides of the front side of the connecting plate 401, and a wire hole 405 is opened on the top of the baffle plate 404.

[0034] The plurality of high-count flax yarns to be twisted into one strand are passed into the interior of the spinning machine body 403 through the wire holes 405 on the upper side, and the high-count flax yarn twisted into one strand passes through the wire holes 405 on the lower side, and is wound up on the outside of the two shielding covers. The arrangement of the shielding plate 404 and the wire holes 405 makes it convenient to lead the high-count flax yarn into the interior of the spinning machine body 403. At the same time, the arrangement of winding up the high-count flax yarn on the outside of the two shielding covers prevents the short lint, cotton knots and fiber flocs on the spinning machine body 403 from falling to the outside of the wound-up high-count flax yarn when cleaning them. This also prevents the subsequent winding of the high-count flax yarn from entangling the short lint, cotton knots and fiber flocs.

[0035] In one embodiment, for the above-mentioned first shielding cover 2, the top and bottom of the first shielding cover 2 and the second shielding cover 3 are both provided with through grooves 10, the shielding plate 404 is movably connected to the corresponding through grooves 10, and the front of the first shielding cover 2 and the second shielding cover 3 are both provided with glass 11.

[0036] When the first shielding cover 2 and the second shielding cover 3 are closed together, the two shielding plates 404 can be directly moved to the inside of the corresponding through groove 10, so that the sealing of the first shielding cover 2 and the second shielding cover 3 after they are closed together can be ensured, and at the same time, the internal conditions of the two closed shielding covers can be conveniently checked through the glass.

[0037] In one embodiment, for the above-mentioned driving component 6, the driving component 6 includes a driving bar 601, and the driving bar 601 is movably connected to the driving slot 5. The driving bar 601 is arranged on the back of the first shielding cover 2 and the second shielding cover 3. The driving slot 5 is internally rotatably connected with a bidirectional screw 602, and the bidirectional screw 602 is threadedly connected to the driving bar 601. A motor 603 is fixedly installed on one side of the mounting plate 1, and the output end of the motor 603 is fixedly connected to one end of the bidirectional screw 602. The driving slot 5 is provided with multiple ones, and the driving slot 5 is internally fixedly connected with a guide column 604, and the first shielding cover 2 and the second shielding cover 3 are movably connected to the guide column 604 through the corresponding driving bar 601.

[0038] By driving the motor 603, the motor 603 drives the bidirectional screw 602 to rotate, and the bidirectional screw 602 drives the first shielding cover 2 and the second shielding cover 3 through the two driving bars 601, so that the two shielding covers complete the covering of the spinning component 4. At the same time, the guide column 604 can guide the two moving shielding covers through the corresponding driving bar 601, so that the stability of the shielding covers when moving can be guaranteed. At the same time, with the support of the two guide columns 604, the stability of the two shielding covers when covering the spinning component 4 can be guaranteed.

[0039] In one embodiment, for the above-mentioned blowing component 7, the blowing component 7 includes a wind plate 701, the wind plate 701 is fixed on one side of the first shielding cover 2, the front of the wind plate 701 is inside the first shielding cover 2, the front of the wind plate 701 is fixedly connected with a nozzle 702, the back of the wind plate 701 is fixedly connected with a connecting pipe 703, the gathering component 8 includes a gathering cover 801, the gathering cover 801 is fixedly connected to the back of the second shielding cover 3, the back of the gathering cover 801 is fixedly connected with a pressure relief pipe 802, the inner wall of the pressure relief pipe 802 is obliquely provided with a gauze 803, the bottom of the inner wall of the pressure relief pipe 802 is provided with a collecting groove 804, and the collecting groove 804 is located on the inner side of the gauze 803.

[0040] The external air supply device can be connected to the connecting tube 703, so that the air supply device can transport airflow to the inside of the wind plate 701 through the connecting tube 703. When cleaning the short fluff, cotton knots and fiber flocs on the spinning machine body 403, the nozzle 702 can spray the airflow from the inside of the wind plate 701. At this time, the short fluff, cotton knots and fiber flocs on the spinning machine body 403 float toward the gathering cover 801 under the blowing of the air flow and the guidance of the first shielding cover 2 and the second shielding cover 3. At the same time, the short fluff, cotton knots and fiber flocs directly float to the inside of the pressure relief pipe 802 under the guidance of the gathering cover 801. At this time, the airflow The lint, cotton knots and fiber flocs can flow from the gauze 803 to the outside of the pressure relief pipe 802, and the gauze 803 blocks the lint, cotton knots and fiber flocs. The blocked lint, cotton knots and fiber flocs can fall into the inside of the collecting tank 804 under the guidance of the inclined gauze 803. The arrangement of the pressure relief pipe 802 and the gauze 803 prevents the flowing airflow from blowing the lint, cotton knots and fiber flocs collected inside the collecting component 9, so that the collecting component 9 can better collect the lint, cotton knots and fiber flocs. At the same time, the inclined arrangement of the gauze 803 prevents the lint, cotton knots and fiber flocs from accumulating on the gauze 803.

[0041] In one embodiment, for the above-mentioned collecting component 9, the collecting component 9 includes a connecting frame 901, and the connecting frame 901 is fixedly connected to the bottom of the pressure relief pipe 802 corresponding to the collecting groove 804, and the bottom end of the connecting frame 901 is fixedly connected to a supporting frame 902, and the inside of the supporting frame 902 is movably connected to a collecting box 903, and a supporting column 904 is fixedly connected between one side of the supporting frame 902 and the bottom of the second shielding cover 3.

[0042] The short lint, cotton knots and fiber flocs inside the collecting groove 804 can fall directly into the collecting box 903 under the guidance of the connecting frame 901. When cleaning the short lint, cotton knots and fiber flocs collected inside the collecting box 903, the collecting box 903 can be directly moved out from the connecting frame 901. The whole cleaning process is relatively convenient. At the same time, the setting of the support column 904 enables the support frame 902 to better support the collecting box 903.

[0043] In summary, with the aid of the above-mentioned technical scheme of the utility model, a plurality of high-count flax yarns to be twisted into one strand are passed through the wire hole 405 on the upper side into the interior of the spinning machine body 403, and at the same time, the high-count flax yarn twisted into one strand passes through the wire hole 405 on the lower side and is fixed on the external winding device of the two shielding covers, and then the motor 603 is driven, and the motor 603 drives the bidirectional screw 602 to rotate, and the bidirectional screw 602 drives the first shielding cover 2 and the second shielding cover 3 through the two driving bars 601, so that the two shielding covers complete the covering of the spinning assembly 4, and at this time, the air supply device transports the airflow to the interior of the wind plate 701 through the connecting pipe 703, and the nozzle 702 sprays the airflow inside the wind plate 701 out The short fluff, cotton knots and fiber flocs on the spinning machine body 403 float toward the gathering cover 801 under the blowing of the air flow and the guidance of the first shielding cover 2 and the second shielding cover 3. At the same time, the short fluff, cotton knots and fiber flocs float directly to the inside of the pressure relief pipe 802 under the guidance of the gathering cover 801. At this time, the air flow can flow from the gauze 803 to the outside of the pressure relief pipe 802. At the same time, the gauze 803 blocks the short fluff, cotton knots and fiber flocs. The blocked short fluff, cotton knots and fiber flocs can fall directly into the inside of the collecting box 903 through the collecting groove 804 and the connecting frame 901 under the guidance of the inclined gauze 803. When the short fluff, cotton knots and fiber flocs collected in the collecting box 903 are cleaned, the collecting box 903 can be directly moved out from the inside of the connecting frame 901.

[0044] Through the above technical scheme, 1. The first shielding cover 2 and the second shielding cover 3 can be closed together through the driving component 6 to cover the spinning component 4 in all directions, so that when the blowing component 7 blows the short lint, cotton knots and fiber flocs on the spinning component 4, the first shielding cover 2 and the second shielding cover 3 can guide the floating short lint, cotton knots and fiber flocs and make them float directly to the inside of the gathering component 8, and then the collecting component 9 collects the short lint, cotton knots and fiber flocs inside the gathering component 8. The above arrangement enables the collecting component 9 to collect the short lint, cotton knots and fiber flocs inside the gathering component 8 under the shielding and guidance of the first shielding cover 2 and the second shielding cover 3. 1. All the short fluff, cotton knots and fiber flocs blown down from the part 4 are collected, thereby improving the overall cleaning effect of the cleaning device; 2. By driving the motor 603, the motor 603 can drive the first shielding cover 2 and the second shielding cover 3 to separate through the bidirectional screw 602 and the driving bar 601, and no longer shield the spinning machine body 403. In addition, the setting of the shielding plate 404 and the thread hole 405 makes it more convenient to guide the high-count flax yarn into the interior of the spinning machine body 403, and the two shielding covers will not affect the movement of the high-count flax yarn and the high-count flax yarn after they are closed together.
