Detailed implementation manners

[0053] To more clearly understand the technical solutions in this application, the related technologies will be described first.

[0054] The fiber material has been made into a continuous strip-shaped semi-finished product through the opening and carding processes in the previous processes, but it cannot be directly spun into fine yarn because there is still a large gap between the quality and structural state of the sliver and the requirements of the final yarn. The straightening degree and separation degree of the fibers are both poor.

[0055] For example, most of the fibers in the sliver are still in a buckled or hooked state, and there are also some small fiber bundles; while the combed sliver has better fiber straightening degree, but its evenness is poor. If these slivers are directly spun into yarn after roving, it will inevitably affect the yarn quality. Therefore, they must all be processed through the drawing process first.

[0056] At this time, 6-8 cotton slivers need to be first combined and fed into the drawing frame to make one cotton sliver. Since the thick and thin sections of each cotton sliver have the opportunity to overlap with each other, the unevenness of the long section of the sliver is improved. The weight unevenness of the sliver is about 4.0% or so, and after combination, the weight unevenness of the drawn sliver should be reduced to less than 1%.

[0057] This process is accompanied by the drafting and mixing processes at the same time. On the one hand, it is for diameter control and improving the fiber state, and on the other hand, it is for performance improvement through the mixing of different materials (blending, integrating the advantages of different materials).

[0058] The roving frame is a key equipment in the textile industry for processing fiber sliver (roving) into roving. Its core function is to provide a suitable intermediate product for the spinning process through drafting, twisting, and winding forming.

[0059] The yarn obtained from the drawing process is generally placed in a yarn bobbin, then transported to the roving frame for use. At this time, the yarn is wound and layered in the yarn bobbin, and when in use, the yarn is sequentially pulled out from the yarn bobbin through tension.

[0060] The following further elaborates on the technical solutions in this application in conjunction with the accompanying drawings.

[0061] This application discloses a combined drawing and roving frame system. In some examples, the combined drawing and roving frame system disclosed in this application includes a guiding track 1, a transport trolley 2, and an automatic wire connecting module 3. The drawing frame and the roving frame are respectively arranged at both ends of the guiding track 1. Generally, the guiding track 1 uses a circular track or a C-shaped track, and the yarn bobbins on the drawing frame side and the roving frame side are both arranged in a single row.

[0062] Please refer to Figure 1 and Figure 2 , the transport trolley 2 is arranged on the guiding track 1, and the transport trolley 2 is configured to transport the yarn bobbin to move on the guiding track 1. When using a circular track, the moving mode of the transport trolley 2 is one-way movement, and when using a C-shaped track, the moving mode of the transport trolley 2 is reciprocating movement.

[0063] The automatic wire connecting module 3 is independently arranged or installed on the roving frame, and is used to connect the yarn. Here, connecting the yarn means connecting the end of the yarn in the previous yarn bobbin with the start end of the yarn in the next yarn bobbin, which can enable the roving frame to carry out continuous production and at the same time liberate the manpower from this work.

[0064] Please refer to Figure 3 , the transport trolley 2 includes a moving vehicle body 21, a horizontal linear moving module 22, a rotating table 23, and a transport belt module 24. Specifically, the horizontal linear moving module 22 is fixedly installed on the moving vehicle body 21, and the moving direction of the horizontal linear moving module 22 is perpendicular to the moving direction of the moving vehicle body 21, and its main function is to adjust the positions of the rotating table 23 and the transport belt module 24.

[0065] This is because during the process of taking the yarn bobbin, the transport belt module 24 needs to move closer to and away from in the horizontal direction to cooperate with the push rod to realize the movement of the yarn bobbin and at the same time avoid physical contact, and this process needs to be realized by the horizontal linear moving module 22.

[0066] The rotating table 23 is installed on the horizontal linear movement module 22, and two conveyor belt modules 24 are symmetrically arranged on the rotating table 23. The first conveyor belt module 24 is responsible for transferring the yarn bobbins filled with yarn, and the second conveyor belt module 24 is responsible for transferring the empty yarn bobbins.

[0067] The rotating table 23 realizes the position exchange of the two conveyor belt modules 24 by rotation.

[0068] For example, as Figure 4 shown, at the drawing frame process, the yarn bobbin filled with yarn ( Figure 4 No. 1 in Figure 4 ) is first transferred to the first conveyor belt module 24, and then the transport cart 2 will move to the roving process. At this time, the empty yarn bobbin (

[0069] No. 2 in

[0070] ) is first transferred to the second conveyor belt module 24, and then the rotating table 23 rotates 180°. The first conveyor belt module 24 transfers the yarn bobbin filled with yarn to the vacant position at the roving process.

[0071] Please refer to Figure 5 , the automatic wire connecting module 3 includes a lifting table 31, a negative pressure operating table 32 and a separator 33 (not shown). The lifting table 31 is independently arranged or installed on the roving frame. Two negative pressure operating tables 32 are both arranged on the lifting table 31 and can be adjusted in the height direction along with the lifting table 31.

[0072] There is a gap between the two negative pressure operating tables 32 and the width of the gap is adjustable. This part will be introduced later.

[0073] The separator 33 is also arranged on the lifting table 31. The working end of the separator 33 can extend into the space between the first negative pressure operating table 32 and the second negative pressure operating table 32. The function of the separator 33 is to loosen the yarn, and then cooperate with the two negative pressure operating tables 32 to realize the connection between the end of the yarn in the previous yarn bobbin and the start of the yarn in the next yarn bobbin.

[0074] At this time, it is required that at least one negative pressure operating table 32 can move in a direction perpendicular to the working direction of the lifting table 31, that is, in the horizontal direction, and the two negative pressure operating tables 32 can move relative to each other. The relative movement mode of the two negative pressure operating tables 32 can twist the end of the yarn in the upper yarn bobbin together with the beginning of the yarn in the lower bobbin.

[0075] Please refer to Figure 5 , the negative pressure operating table 32 includes a telescopic unit 321, a first linear movement module 322 and a negative pressure adsorption plate 323. The telescopic unit 321 is detachably and fixedly connected to the lifting table 31. Generally, a linear motor is used for the telescopic unit 321 here, and the first linear movement module 322 is installed on the telescopic unit 321.

[0076] The moving direction of the first linear movement module 322 is perpendicular to the moving direction of the telescopic unit 321. The function of the telescopic unit 321 is to adjust the gap width between the two negative pressure operating tables 32, and the function of the first linear movement module 322 is to enable the two negative pressure operating tables 32 to move relative to each other in the horizontal direction.

[0077] The negative pressure adsorption plate 323 is fixed on the first linear movement module 322. A negative pressure cavity 324 is provided inside the negative pressure adsorption plate 323, and adsorption holes 325 are provided on the working surface of the negative pressure adsorption plate 323. The adsorption holes 325 are communicated with the negative pressure cavity 324, as Figure 6 shown.

[0078] The negative pressure adsorption plate 323 realizes negative pressure through an external pipeline. Here, the external pipeline is connected to a connecting nozzle on the negative pressure adsorption plate 323, and the connecting nozzle is communicated with the negative pressure cavity 324.

[0079] The function of the negative pressure adsorption plate 323 is to cooperate with the separator 33 to separate the cotton yarn. The separation here refers to unfolding the yarn with a circular or quasi-circular cross-sectional shape on the negative pressure adsorption plate 323, and the shapes of the end of the yarn in the upper yarn bobbin and the beginning of the yarn in the lower bobbin both become fan-shaped.

[0080] The fan shape can increase the contact area between the two sections of yarn. At this time, combined with the relative movement between the two negative pressure adsorption plates 323, the end of the yarn in the upper yarn bobbin can be twisted together with the beginning of the yarn in the lower bobbin.

[0081] Please refer to Figure 7 , the separator 33 includes a horizontal position adjustment module 331, a second linear telescopic module 332 and an electric push rod 333. The horizontal position adjustment module 331 is fixedly installed on the lifting table 31, the electric push rod 333 is fixedly installed on the second linear telescopic module 332, and the separation claw 4 is installed on the second linear telescopic module 332 and connected to the electric push rod 333.

[0082] Specifically, the horizontal position adjustment module 331 is responsible for realizing the movement in the horizontal direction, aiming to adjust the distance between the separating claw 4 and the two negative pressure adsorption plates 323. The second linear telescopic module 332 is responsible for the movement in the vertical direction, and the electric push rod 333 is responsible for driving the separating claw 4.

[0083] As can be seen in Figure 7 , the thick solid line on the left is the end of the yarn in the upper yarn bobbin, and the thick solid line on the right is the start of the yarn in the lower bobbin. The movement of the horizontal position adjustment module 331 in the horizontal direction aims to make the separating claw 4 contact these two yarns respectively.

[0084] The end of the yarn in the upper yarn bobbin needs to be adjusted from top to bottom, and the end of the yarn in the lower yarn bobbin needs to be adjusted from bottom to top, which exactly corresponds to a complete reciprocating movement of the second linear telescopic module 332.

[0085] Please refer to Figure 7 and Figure 8 . The separating claw 4 includes a main body pipe 41, a piston 42, a claw body 43 and a guiding body 44. The main body pipe 41 is fixedly installed on the second linear telescopic module 332. The piston 42 is slidably connected to the main body pipe 41 and connected to the electric push rod 333. The electric push rod 333 pushes the piston 42 to reciprocate inside the main body pipe 41.

[0086] The first end of the claw body 43 is hinged to the piston 42, and the second end is a free end. The purpose of the hinge is to allow local angle adjustment of the first end of the claw body 43. As can be seen through Figure 8 , when the claw body 43 retracts into the main body pipe 41, the distance between the second ends is relatively close. When the claw body 43 extends out of the main body pipe 41, the distance between the second ends is relatively far. This requires the claw body 43 to be made of an elastic material.

[0087] The guiding body 44 is arranged on the main body pipe 41 or the second linear telescopic module 332, and its function is to guide the moving direction of the claw body 43. Multiple guiding holes are arranged on the guiding body 44, and each claw body 43 passes through the corresponding guiding hole. The guiding holes are used to increase the distance between the second ends of adjacent claw bodies 43. That is, for two adjacent guiding holes, the axial directions are not parallel.

[0088] The guiding holes can also force the claw body 43 to bend.

[0089] In some possible implementation manners, the guiding hole includes a straight section parallel to the axis of the main body pipe 41 and an inclined section not parallel to the axis of the main body pipe 41.

[0090] In this way, when the extending length of the claw body 43 increases, the distance between the second ends of adjacent claw bodies 43 will also increase synchronously. In this way, the shape of the end of the yarn in the previous yarn bobbin and the start of the yarn in the next bobbin can be changed into a fan shape.

[0091] For the automatic wire connecting module 3, multiple automatic wire connecting modules 3 can be set at different fixed positions, or a single automatic wire connecting module 3 can be deployed using a lateral movement method. The automatic wire connecting module 3 is generally located between the roving frame and the yarn bobbin.

[0092] In some examples, refer to Figure 9 , a yarn loading module 5 is also added. The function of the yarn loading module 5 is to automate the picking up of the start of the yarn in the next bobbin. Specifically, the yarn loading module 5 includes a manipulator 51, a negative pressure adsorption hood 52, and a purging pipeline 53. The negative pressure adsorption hood 52 is fixed at the moving end of the manipulator 51 and can adjust its position within a three-dimensional coordinate system as the manipulator 51 moves.

[0093] The purging pipeline 53 is also fixed at the moving end of the manipulator 51 and faces the negative pressure adsorption hood 52. Its function is to blow the start of the yarn in the next bobbin into the interior of the negative pressure adsorption hood 52 through an air flow. At this time, the negative pressure adsorption hood 52 adsorbs a part of the start of the yarn in the next bobbin on the inner wall of the negative pressure adsorption hood 52.

[0094] At this time, when the manipulator 51 moves to the negative pressure adsorption plate 323, the handover of the start of the yarn in the next bobbin can be achieved.

[0095] From the above description, it can be seen that a channel needs to be set on the negative pressure adsorption hood 52 at this time, or the negative pressure adsorption hood 52 needs to be composed of two semi-adsorption hoods, so that after the handover of the start of the yarn in the next bobbin is completed, the negative pressure adsorption hood 52 can be disengaged from the yarn in the next bobbin.

[0096] Refer to Figure 10 , in this application, a section of yarn needs to be reserved on the outer wall of the yarn bobbin, and the general length is controlled at about 15 - 20 centimeters. As Figure 10 shown, the negative pressure adsorption hood 52 first moves to press this reserved section of yarn. At this time, the purging pipeline 53 blows air, causing this section of yarn to pass through the negative pressure adsorption hood 52. Then the negative pressure adsorption hood 52 is activated to adsorb the middle part of this section of yarn through the holes on the inner wall. The head of this section of yarn protrudes from the upper end of the negative pressure adsorption hood 52 and remains vertical with the support of the purging pipeline 53.

[0097] From the description of this section of content, it can be seen that there are only holes in a limited area on the inner wall of the negative pressure adsorption hood 52, and the purpose is to adsorb the yarn at a fixed position.

[0098] Next, the manipulator 51 drives the yarn exposed from the upper end of the purging pipeline 53 to move to the negative pressure adsorption plate 323 and is adsorbed by the negative pressure adsorption plate 323.

[0099] The embodiments of the specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
