Description

Technical Field

[0001] The invention relates to the technical field of spinning, in particular to a cotton cleaning device for a spinning frame. Background Art

[0002] The spinning frame is the primary spinning machine that drafts, twists, and winds semi-finished roving or sliver into cops. The sliver is drafted and twisted on the roving frame to create roving, the comber combs the fibers to create combed sliver, the gilling frame combines the slivers, and the pins draft to improve the sliver structure. The roving is further twisted and spun into fine yarn on the ring spinning frame. The spinning frame is the primary spinning machine. The yield and quality of fine yarn are a comprehensive reflection of the quality of each spinning process.

[0003] A cotton cleaning device needs to be installed in the spinning frame to clean the textile yarn. For example, the Chinese utility model patent with the authorization announcement number CN209052824U discloses a flow-guiding cotton cleaning device for textile production, which has columns symmetrically arranged on both sides of the textile yarn. The columns are hinged with telescopic rods on the side opposite to the textile yarn, and the ends of the telescopic rods are fixed and hinged through a cover plate; a plurality of diversion grooves are provided on the lower end surface of the cover plate along the length direction of the textile yarn, and a plurality of exhaust pipes are provided on the bottom end surface of the guide groove along the length direction. The upper ends of the exhaust pipes are connected to the main pipeline after passing through the cover plate. The upper end of the main pipeline is connected to one side of the exhaust pump through a pipeline, and the other side of the exhaust pump is connected to the impurity removal box. The flow-guiding cotton cleaning device for textile production has a simple structure and promotes rapid flow and cleaning of the textile yarn.

[0004] The above utility model patent has the following shortcomings: the main function of the guide groove is to guide the flow of the textile thread, and the cotton cleaning and impurity removal mainly rely on the airflow formed by the exhaust pump. Although a certain cotton cleaning and impurity removal effect can be achieved, it still needs to be further improved to meet the production requirements of higher quality yarn. Summary of the Invention

[0005] The purpose of the present invention is to provide a spinning frame cotton cleaning device with good cotton cleaning and impurity removal effects.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a spinning frame cotton cleaning device, comprising a seat plate, a plurality of air flow ducts, a collecting pipe, and an exhaust device installed on the collecting pipe, the seat plate is provided with a plurality of guide grooves, the two ends of the air flow duct are respectively an air inlet and an air outlet, the air inlet is located on the inner wall of the guide groove, the air outlet is connected to the collecting pipe, an elastic steel sheet is installed on the seat plate, the elastic steel sheet is used to contact the textile line in the guide groove, the seat plate is slidingly provided with a detection seat, a pressure resistive sensor is installed on the detection seat, the pressure resistive sensor is used to contact the elastic steel sheet, and the pressure resistive sensor is connected to a detection circuit.

[0007] By adopting this technical solution, the textile yarn moves forward and passes through the guide groove. The elastic steel sheet contacts the textile yarn and scrapes away the cotton and debris attached to its surface, improving the cleaning effect. The exhaust device operates to generate airflow, which carries away the cotton and debris scraped off the textile yarn.

[0008] If the shape of the elastic steel sheet changes significantly during long-term operation, the interaction force between the elastic steel sheet and the textile thread may be too small or too large. If it is too small, the scraping effect will be unsatisfactory, while if it is too large, the textile thread may become taut or even break. Considering that the elastic steel sheet is deformed during normal operation, it is impossible to detect whether the position of the elastic steel sheet is within the normal range. Therefore, after the equipment is shut down, it is necessary to move the detection base to the designed designated position and the pressure resistance sensor to the designated position. By determining the pressure applied to the pressure resistance sensor, it can be determined whether the shape of the elastic steel sheet has been permanently deformed and whether it needs to be replaced.

[0009] The present invention is further configured such that: along the moving direction of the textile line, the elastic steel sheet is located upstream of the air inlet or the elastic steel sheet is located at the air inlet.

[0010] By adopting the above technical solution, the scraped cotton wool and debris can be discharged from the air flow duct along with the air flow.

[0011] The present invention is further configured as follows: the elastic steel sheet includes a middle section and a contact section connecting the two ends of the middle section, the two contact sections respectively contact different positions of the textile line in the guide groove, and the number of the pressure resistive sensors is two and corresponds to the two contact sections respectively.

[0012] The present invention is further configured as follows: the detection seat includes a block seat and several seat bodies fixed to the block seat, the seat plate is provided with several sockets, the lower ends of the sockets are connected to the interior of the guide groove, the seat bodies are inserted into the sockets, and the block seat is threaded with bolts, which rest against the upper end surface of the seat plate.

[0013] By adopting the above technical solution, the bolt abuts against the end surface of the seat plate, preventing the detection seat and the pressure resistance sensor from contacting and interfering with the normal operation of the elastic steel sheet. When the position of the elastic steel sheet needs to be checked, the adjustment bolt is rotated to disengage it from the seat plate, and the stopper automatically descends to a position that abuts the seat plate.

[0014] The present invention is further configured as follows: it also includes a debris removal box, which is installed in the middle of the collecting pipe, a debris removal channel is formed in the debris removal box, a first filter screen and a second filter screen are provided in the debris removal channel, a debris collection chamber is formed in the debris removal box, a first connecting port and a second connecting port are formed on the side wall of the debris removal channel, the first connecting port and the second connecting port connect the debris removal channel with the debris collection chamber, and the debris removal box is provided with a driving assembly, and the driving assembly is used to drive the first filter screen to pass through the first connecting port and drive the second filter screen to pass through the second connecting port.

[0015] By adopting the above technical solution, in order to improve the level of automation and reduce manual work, the present invention adopts the design of a first filter and a second filter. When there is too much debris attached to the first filter, it will affect the passage of airflow. At this time, the driving component drives the first filter through the first connection port and enters the debris collection chamber from the debris removal channel, and the debris attached to the first filter falls into the debris collection chamber. When there is enough debris attached to the second filter or the time is long enough, the driving component drives the first filter from the debris collection chamber into the debris removal channel, and the second filter from the debris channel into the debris collection chamber, and the debris attached to the second filter falls into the debris collection chamber.

[0016] The present invention is further configured as follows: two first rubber strips are fixed to the side walls on both sides of the first connecting port, and two second rubber strips are fixed to the side walls on both sides of the second connecting port.

[0017] By adopting the above technical solution, the first rubber strip and the second rubber strip are used to reduce the gas exchange between the impurity removal channel and the debris collection chamber, thereby preventing the airflow in the impurity removal channel from affecting the debris collection chamber.

[0018] The present invention is further configured as follows: the first filter screen includes a first frame body and a first mesh body installed in the middle of the first frame body, and the distance between the first mesh body and the end face of the first frame body is greater than or equal to the thickness of the first rubber strip; the second filter screen includes a second frame body and a second mesh body installed in the middle of the second frame body, and the distance between the second mesh body and the end face of the second frame body is greater than or equal to the thickness of the second rubber strip.

[0019] By adopting the above technical solution, when the first filter screen passes through the first connection port, the interference of the first rubber strip on the debris attached to the first filter screen is reduced. When the second filter screen passes through the second connection port, the interference of the second rubber strip on the debris attached to the second filter screen is reduced.

[0020] The present invention is further configured as follows: a first brush body and a second brush body are fixed to the inner wall of the debris collection chamber, the first brush body is used to brush off debris on the first filter screen, and the second brush body is used to brush off debris on the second filter screen.

[0021] The present invention is further configured as follows: the drive assembly includes a cylinder, a rocker arm hinged to the inner wall of the debris collection chamber, a first connecting rod and a second connecting rod hinged to the rocker arm, the first connecting rod is hinged to the first filter screen, the second connecting rod is hinged to the second filter screen, a first slide rail and a second slide rail are provided in the debris removal box, the first filter screen is slidably connected to the first slide rail, the second filter screen is slidably connected to the second slide rail, and the cylinder piston rod is hinged to the rocker arm.

[0022] By adopting the above technical solution, the cylinder piston rod extends to drive the rocker arm to move. The rocker arm drives the first filter screen to move through the first connecting rod and drives the second filter screen to move through the second connecting rod. The movement directions of the first filter screen and the second filter screen are opposite.

[0023] The present invention is further configured as follows: a third filter is installed in the impurity removal channel, and along the airflow direction, the first filter is located upstream of the second filter, and the second filter is located upstream of the third filter.

[0024] By adopting the above technical solution, during the switching process between the first filter and the second filter, a small amount of debris will pass through with the airflow, so a third filter is set to perform filtering.

[0025] The beneficial effects of the present invention are: 1. The present invention uses a detection seat, a pressure resistance sensor and a detection circuit to determine whether the detection value of the sensor is within the normal value range to determine whether the position and shape of the elastic steel sheet have changed, thereby controlling the relative position and interaction force between the elastic steel sheet and the textile thread. When scraping away cotton wool and debris, it can not only ensure the scraping effect, but also prevent the textile thread from being damaged or even broken due to excessive force.

[0026] 2. The present invention uses a drive assembly to adjust the positions of the first and second filters, enabling automated switching between them. Filtering occurs within the debris removal channel or debris is brushed off within the debris collection chamber. This highly automated system eliminates the need for manual intervention to clean debris from the first and second filters; only pre-set cylinder actuation timing is required. Furthermore, a single cylinder in the drive assembly drives the movement of both filters, reducing manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The technical solutions of the present invention will be described clearly and completely below with reference to specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0037] A spinning frame cleaning device, such as Figure 1 、 Figure 2 、 Figure 3As shown, the base plate 1 includes a plurality of airflow ducts 2 and a collection pipe 3. The lower end of the base plate 1 is provided with a plurality of guide grooves 11, each corresponding to each of the airflow ducts 2. The airflow ducts 2 have an air inlet and an air outlet at either end, respectively. The air inlet is located on the inner wall of the guide groove 11, and the air outlet is connected to the interior of the collection pipe 3. The base plate 1 is mounted with a plurality of elastic steel plates 7, each corresponding to each of the guide grooves 11. The elastic steel plates 7 include a middle section 71 and two contact sections 72 connected at both ends of the middle section 71. The two contact sections 72 are used to contact different positions of the textile yarn within the guide groove 11. Along the direction of movement of the textile yarn, the elastic steel plates 7 are located upstream of the air inlet.

[0038] like Figure 2 、 Figure 3 As shown, a detection seat 6 is provided on the seat plate 1, and the detection seat 6 includes a block seat 61 and a plurality of seat bodies 62 fixed on the block seat 61. A plurality of sockets 12 are provided on the upper end surface of the seat plate 1, the upper end opening of the socket 12 is located on the upper end surface of the seat plate 1, and the lower end opening is located on the inner wall of the guide groove 11. The plurality of seat bodies 62 are respectively plugged into the plurality of sockets 12. A bolt 64 is threadedly connected to the block seat 61, and the lower end of the bolt 64 rests on the upper end surface of the seat plate 1. Two pressure resistive sensors 63 are installed on each seat body 62, and the two pressure resistive sensors 63 are respectively used to detect the two contact sections 72. The pressure resistive sensor 63 is connected to a detection circuit.

[0039] Working principle of detection base 6: When the cotton cleaning device is operating normally, multiple textile threads pass through multiple guide grooves 11, and the two contact sections 72 of the elastic steel sheet 7 contact different positions of the textile threads, scraping away cotton and debris attached to the textile threads. When the cotton cleaning device stops operating, the bolt 64 is rotated to retract its lower end into the stopper 61, and the stopper 61 and the base 62 both descend. The pressure resistance sensor 63 on the base 62 contacts the elastic steel sheet 7, and the detection circuit detects the value of the pressure resistance sensor 63. By comparing the detected value to see if it is within the normal range, it can be determined whether the position of the elastic steel sheet 7 is normal and whether it needs to be replaced.

[0040] like Figure 4 、 Figure 5 As shown, the spinning frame cleaning device also includes a dust removal box 4 and an exhaust device, both of which are mounted on the collection pipe 3. A dust removal channel 43 is formed within the dust removal box 4, with both ends of the channel 43 connected to the collection pipe 3. A first filter screen 41, a second filter screen 42, and a third filter screen are mounted within the channel 43. In the direction of airflow, the first filter screen 41 is located upstream of the second filter screen 42, and the second filter screen 42 is located upstream of the third filter screen.

[0041] like Figure 6 、 Figure 7As shown, a debris collection chamber 44 is formed in the debris removal box 4, and a first connection port 45 and a second connection port 46 are formed on the side wall of the debris removal channel 43. The first connection port 45 and the second connection port 46 connect the debris removal channel 43 with the debris collection chamber 44. A first slide rail 8 and a second slide rail 9 are installed in the debris removal box 4. The first filter screen 41 is slidably connected to the first slide rail 8 and can slide along the first slide rail 8. It can enter the debris collection chamber 44 from the debris removal channel 43 through the first connection port 45, and can also enter the debris collection chamber 44 from the debris collection chamber 44 through the first connection port 45. The second filter screen 42 is slidably connected to the second slide rail 9 and can slide along the second slide rail 9. It can enter the debris collection chamber 44 from the debris collection chamber 43 through the second connection port 46, and can also enter the debris removal channel 43 from the debris collection chamber 44 through the second connection port 46.

[0042] like Figure 6 As shown, two first rubber strips are fixed to the side walls of the first connection port 45, and two second rubber strips are fixed to the side walls of the second connection port 46. The first filter 41 includes a first frame 411 and a first mesh 412 mounted in the middle of the first frame 411. The distance between the first mesh 412 and the end face of the first frame 411 is greater than or equal to the thickness of the first rubber strip. The second filter 42 includes a second frame 421 and a second mesh 422 mounted in the middle of the second frame 421. The distance between the second mesh 422 and the end face of the second frame 421 is greater than or equal to the thickness of the second rubber strip. A first brush 441 and a second brush 442 are fixed to the inner wall of the debris collection chamber 44. The first brush 441 is used to brush debris off the first filter 41, and the second brush 442 is used to brush debris off the second filter 42.

[0043] like Figure 6 、 Figure 7 As shown, the debris removal box 4 is provided with a drive assembly 5, which is used to drive the first filter 41 through the first connection port 45 and the second filter 42 through the second connection port 46. The drive assembly 5 includes a cylinder 51, a swing arm 52 hinged to the inner wall of the debris collection chamber 44, and a first connecting rod 53 and a second connecting rod 54 hinged to the swing arm 52. The first connecting rod 53 is hinged to the first filter 41, and the second connecting rod 54 is hinged to the second filter 42. The piston rod of the cylinder 51 is hinged to the swing arm 52.

[0044] Working principle of the debris removal box 4: The first filter 41 is located in the debris removal channel 43 and plays a filtering role. The second filter 42 is located in the debris collection chamber 44 for standby. When there is too much cotton wool and debris attached to the first filter 41, the piston rod of the cylinder 51 extends, driving the rocker arm 52 to move. The rocker arm 52 drives the first filter 41 to move through the first connecting rod 53, and drives the second filter 42 to move through the second connecting rod 54. The first filter 41 passes through the first connecting port 45 from the debris removal channel 43 and enters the debris collection chamber 44. The second filter 42 passes through the second connecting port 46 from the debris collection chamber 44 and enters the debris removal channel 43. The cotton wool and debris attached to the first filter 41 are brushed off by the first brush body 441 and fall into the debris collection chamber 44. The second filter 42 is located in the debris removal channel 43 and plays a filtering role. When there are enough cotton wool and debris attached to the second filter screen 42, the piston rod of the cylinder 51 retracts, driving the rocker arm 52 to swing. At this time, the second filter screen 42 enters the debris collection chamber 44, and the first filter screen 41 enters the debris removal channel 43 to perform a filtering effect. There is no need to manually clean the debris on the filter screen, thereby improving the level of automation.
