Description

Technical Field

[0001] The present application relates to the technical field of sliver lap machines, and in particular to a sliver lap machine for carding cotton. Background Art

[0002] Sliver lap machine is one of the preparatory machines for cotton combing. It arranges the combed slivers or pre-drawn slivers in parallel to form sliver laps. It is mainly composed of feeding, drafting, pressing and lapping mechanisms. 14-20 slivers are usually drawn out from the sliver cans on both sides, turned 90° by the sliver guide rollers to be arranged in parallel with the sliver guide frame, and enter the drafting device for slight drafting. The pressing roller presses the cotton layer, and the lap rollers wind it onto the bobbin to form a sliver lap for the combing machine.

[0003] In existing sliver lappers, the broken slivers are usually re-twisted manually after they are broken. However, the fibers at the broken slivers are arranged in a disorderly manner, and the creases formed have poor lateral uniformity, which will affect the quality of subsequent combing. Therefore, a sliver lapper that can repair broken slivers well is needed. Utility Model Content

[0004] In order to maintain good lateral uniformity of broken slivers after they are reconnected and repaired, the present application provides a sliver lap machine for carding cotton.

[0005] The present application provides a sliver lap machine for carding that adopts the following technical solution:

[0006] A strip winding machine for carding cotton comprises a plurality of strip barrels arranged at intervals and tilting, cotton strips extending outward from the strip barrels, a guide roller being provided on one side of the strip barrel, a pre-guide structure and a strip guide structure being provided at the front end of the guide roller; repair splints for clamping the cotton strips are sleeved on the upper and lower sides of the cotton strips, the repair splints can be inserted into the pre-guide structure and the strip guide structure; a removal structure is provided on one side of the strip guide structure close to the front end, the strip guide structure being inserted into and abutting against the repair splint; a rolling structure is provided at the front end of the strip guide structure.

[0007] By adopting the above technical solution, adding a repair splint to an ordinary sliver winding machine can help repair and reconnect broken cotton slivers, and the repair splint can be squeezed by the rollers as the cotton slivers move, so as to evenly repair and connect the broken slivers. At the same time, the repair splint can also reduce the force on the broken sliver, so that it can be smoothly moved to other processes. At the same time, the dismantling structure can remove the repair splint at the set position, thereby eliminating the need for manual tracking of the repair splint.

[0008] Preferably, the dismantling structure includes a pressure-resistant guide plate and a guide rail, the pressure-resistant guide plates are respectively fixed on the side of the repair splints away from each other, the pressure-resistant guide plates are elastic, and the front end of the pressure-resistant guide plates is open; the guide rails are respectively fixedly arranged at intervals, and the pressure-resistant track is lower on the side close to the barrel and higher on the side close to the rolling structure, and the guide rail is passed through the front end of the pressure-resistant guide plate on one side of the pressure-resistant guide plate.

[0009] By adopting the above technical solution, the compression-resistant guide plate can maintain its original shape after being compressed and be combined with the guide track, so that the compression-resistant guide plate has good controllability and can move or deform according to the shape of the guide track.

[0010] Preferably, the guide strip structure includes a conveying roller and a pressing roller, the conveying roller rotates up and down and is connected to the cotton strip setting; the pressing roller rotates up and down and is connected to the cotton strip setting, and the pressing roller is located on the side of the conveying roller close to the rolling structure, and the guide track is located between the conveying roller and the pressing roller.

[0011] By adopting the above technical solution, the compacting roller is inverted behind the conveying roller process, so that the cotton strips can be directly wound into rolls after being formed into sheets. By fusing the broken strips with other cotton strips, the force can be dispersed to prevent the broken strips from breaking again due to the pulling of the conveying roller.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] 1. Adding a repair splint to an ordinary sliver lap machine can help to repair and reconnect the broken slivers, and the repair splint can be squeezed by the rollers as the slivers move, so as to evenly repair and connect the broken slivers. At the same time, the repair splint can also reduce the force on the broken sliver, so that it can be smoothly moved to other processes. At the same time, the removal structure can remove the repair splint at the set position, so there is no need for manual tracking of the repair splint;

[0014] 2. The compression guide plate can maintain its original shape after being compressed and is combined with the guide track, so that the compression guide plate has good controllability and can move or deform according to the shape of the guide track;

[0015] 3. The compacting roller is placed inverted behind the conveying roller, so that the cotton strips can be directly wound into rolls after they are formed into sheets. By fusing the broken strips with other strips, the force can be dispersed to prevent the broken strips from breaking again due to the pulling of the conveying roller.

[0019] The present application is further described in detail below in conjunction with the accompanying drawings.

[0020] The present application embodiment discloses a sliver lap machine for carding cotton, referring to Figure 1 It includes a plurality of strip barrels 1 which are arranged at intervals and tilted, and cotton strips extend outward from the strip barrels 1. A guide roller 2 for guiding all the cotton strips to move forward in parallel is provided on one side of the strip barrel 1, and a pre-guide structure 3 is provided at the front end of the guide roller 2.

[0021] Reference Figure 1 The pre-guiding structure 3 includes a sliver guide roller 31 and a pre-traction roller 32. The sliver guide roller 31 rotates up and down and is connected to the cotton strip setting. The sliver guide roller 31 clamps the cotton strip and makes the cotton strip initially stretch laterally; the pre-traction roller 32 rotates up and down and is connected to the cotton strip setting, and pulls the cotton strip forward, and the pre-traction roller 32 is located on the side of the sliver guide roller 31 opposite to the sliver barrel 1.

[0022] Reference Figure 1 A guide strip structure 4 is provided at the front end of the pre-traction roller 32, and the guide strip structure 4 includes a conveying roller 41 and a pressing roller 42. The conveying roller 41 rotates up and down and is connected to the cotton strip setting, and conveys the cotton strip to the rear; the pressing roller 42 rotates up and down and is connected to the cotton strip setting, and the pressing roller 42 is located on the side of the conveying roller 41 away from the pre-traction roller 32. The pressing roller 42 combines and compacts the cotton strips, and a rolling structure 7 is provided on the side of the pressing roller 42 opposite to the conveying roller 41.

[0023] Reference Figure 1 The rolling structure 7 includes a cotton roll 71 and a support belt 72. The cotton roll 71 is wound on the side of the cotton strip relative to the strip barrel 1; the support belt 72 is relatively rotatably connected to the bottom of the cotton roll 71, so as to roll the cotton strip into pieces;

[0024] Reference Figure 1 , 2 When the cotton strip breaks, repair splints 5 that can clamp the cotton strip are sleeved on the upper and lower sides of the cotton strip. The repair splint 5 is a soft magnet, and the upper and lower ends of the repair splint 5 can be magnetically attracted to each other. Since the cotton strip fibers at the broken part of the broken cotton strip are elongated, the cotton strips at both ends of the broken belt are connected by overlapping and applying the repair splint 5 at the broken part. The repair splint 5 can be inserted between the guide roller 31, the pre-traction roller 32, the conveying roller 41 and the pressing roller 42, so as to assist in the connection of the broken cotton strip.

[0025] Reference Figure 1 , 2A dismantling structure 6 for dismantling the repair splint 5 is provided between the conveying roller 41 and the pressing roller 42. The dismantling structure 6 includes a pressure-resistant guide plate 61 and a guide rail 62. The pressure-resistant guide plates 61 are respectively fixed to the side of the repair splint 5 away from each other. The pressure-resistant guide plates 61 are elastic, and the front end of the pressure-resistant guide plates 61 is open; the pressure-resistant guide plate 61 includes an inner plate 611, an outer plate 612 and a connecting plate 613. The outer plate 612 is sleeved on the outside of the repair splint 5 and is elastic, and is inclined toward the side of the barrel 1, and the front end of the outer plate is open near the guide rail 62; the inner plate 611 is accommodated between the inner plate 611 and the repair splint 5 and is elastic, and a gap is left between the inner plate 611 and the outer plate 612.

[0026] Reference Figure 1 , 2 The guide rails 62 are fixedly arranged at intervals, and the compression-resistant rail is lower on the side close to the barrel 1 and higher on the side close to the rolling structure 7. The guide rail 62 is passed through the front end opening of the outer plate 612 on one side of the outer plate 612. The connecting plate 613 is connected to the side of the inner plate 611 and the outer plate 612 relative to the guide rail 62. The connecting plate 613 is used to enhance the connection strength between the inner plate 611 and the outer plate 612.

[0027] The working process of the present application is as follows: when the cotton strip breaks, the repair splint 5 is clamped at both ends of the break to cope with the auxiliary force of the guide roller 31 and the conveying roller 41 of the pre-traction roller 32, and connect the front and rear ends of the break, so that the front and rear ends of the cotton strip can complete the strip roll normally. At the same time, the repair splint 5 applies pressure to the cotton strip to help restore the connection at the break of the cotton strip.

[0028] When the repair splint 5 moves to the guide track 62, the guide track 62 pulls the pressure-resistant guide plate 61 to separate. At this time, the broken part enters between the pressing rollers 42. The pressing rollers 42 gather all the spaced cotton strips and connect the adjacent cotton strips to each other, so that the broken part of the cotton strip that has separated from the repair splint 5 is fused with the adjacent cotton strips and subjected to force together, preventing it from breaking again when being wound around the cotton roll 71.

[0029] At the same time, the guide rail 62 is arranged before the rearmost clamping roller, so that when a break occurs during the front process, the repair splint 5 can be used for repair, so that the repair splint 5 can repair more processes.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
