Description

Technical Field

[0001] The utility model relates to the technical field of strip coiling machine braking, in particular to a strip coiling machine braking component and a strip coiling machine. Background Art

[0002] The sliver lap is a key machine in the textile machinery industry, used for pre-combing preparation. Its primary function is to arrange combed or pre-drawn slivers in parallel to form laps. The sliver lap primarily consists of a sliver feeding mechanism, a drafting mechanism, a compacting mechanism, and a lap-forming mechanism. The sliver is conveyed from the sliver feeding mechanism to the drafting mechanism for slight drafting. After dyeing, the compacting mechanism compacts the sliver layer. Finally, the lap is conveyed to the lap-forming mechanism, where rollers wind the top layer onto bobbins, typically made of aluminum alloy, to form a lap.

[0003] The A191 sliver winding machine is a commonly used sliver winding machine in the textile industry. Traditional A191 sliver winding machines have a low level of automation, requiring manual operation for sliver roll changing. Chinese Patent CN217869268U discloses an automatic tube changing and unwinding device for a sliver winding machine. This modified A191 sliver winding machine uses a chuck to clamp an aluminum tube (i.e., an aluminum alloy bobbin) for winding. The chuck can be controlled to roll to a specified position in the sliver winding machine and eject a fully wound sliver roll, thus improving the A191 sliver winding machine's level of automation. The sliver winding process requires the chuck to be lowered and reset, and during this process, the chuck must be braked. Braking of the chuck is primarily achieved by the sliver winding machine's braking assembly, which includes a cooperating brake wheel and brake belt. The brake wheel is connected to the chuck via a drive mechanism. When the brake belt is tightened, the brake wheel brakes due to friction from the brake belt, which in turn drives the chuck to brake via the drive mechanism.

[0004] In existing sliver reel brake assemblies, the brake belt is tightened by a weight rod and a pneumatic cylinder. The weight rod is rotatably mounted within the sliver reel body. A weight is fixed to the front end of the weight rod, connected to the movable end of the brake belt. A cylinder is located above the rear end of the rod. During the downward return of the chuck, the cylinder's piston rod extends and presses down on the rear end of the rod, lifting the front end and loosening the brake belt. When braking is required, the cylinder's piston rod retracts, causing the front end of the rod to sink under the action of the weight, tightening the brake belt and achieving braking.

[0005] However, the front end of the weight rod in the existing slat winder brake assembly is always pressed down by the weight, which can easily cause the weight rod to deform or even break during long-term use; and the pressure provided by the weight to the weight rod is small and the control accuracy is poor, which has limited braking effect on the brake wheel and chuck. Utility Model Content

[0006] In order to solve the technical problems that the front end of the weight rod in the existing strip winder braking assembly is always pressed down by the weight, which can easily cause the weight rod to deform or even break during long-term use; and the pressure provided by the weight to the weight rod is small, the control accuracy is poor, and the braking effect on the brake wheel and the chuck is limited, the utility model provides a strip winder braking assembly and a strip winder, which can reduce the risk of the brake arm breaking, have a strong braking effect and high control accuracy, and can improve the braking efficiency of the strip winder.

[0007] In the first aspect, the utility model provides a strip winder braking assembly, including a brake wheel, which is connected to a chuck through a drive assembly; a brake belt is provided on the outer side of the wheel rim of the brake wheel, and the two ends of the brake belt are respectively a fixed end and a movable end, and the movable end of the brake belt passes around the brake wheel and is fixedly connected to one end of the brake arm, and the brake arm is rotatably arranged; it also includes a first cylinder, the first cylinder is vertically arranged, and the piston rod of the first cylinder is hinged below the end of the brake arm away from the brake belt.

[0008] Furthermore, the drive assembly includes a drive gear coaxially connected to the brake wheel, the drive gear is meshed with the drive rack, one end of the drive rack is connected to the clamping plate, the clamping plate is rotatably connected to the rotating shaft, and the rotating shaft is connected to the chuck.

[0009] Furthermore, a rim groove is provided on the rim of the brake wheel, and the brake belt can be embedded in the rim groove during the braking process to prevent the brake belt from falling off the brake wheel.

[0010] Furthermore, a connecting shaft is provided on the side of one end of the driving arm connected to the brake belt, and the movable end of the brake belt is connected to the connecting shaft.

[0011] In the second aspect, the utility model provides a strip winding machine, which uses the above-mentioned strip winding machine braking assembly, including a machine body, a brake wheel rotatably arranged in the machine body; the fixed end of the brake belt is fixed in the machine body; the brake arm is rotatably connected to the machine body, and the end of the brake arm away from the brake belt extends out of the machine body; the cylinder barrel of the first cylinder is connected to the machine body.

[0012] Furthermore, it also includes a second cylinder, which is vertically arranged, the cylinder barrel of the second cylinder is connected to the body, and the piston rod of the second cylinder is hinged above the end of the brake arm away from the brake belt.

[0013] The beneficial effects of the present invention are:

[0014] The utility model uses a first cylinder to control the rotation of the brake arm. The extension of the piston rod of the first cylinder can push the brake arm to rise away from one end of the brake belt, thereby driving the end of the brake arm connected to the brake belt to descend and tighten the brake belt, thereby achieving braking of the brake wheel and the chuck, eliminating the use of a heavy hammer, and the brake arm will not be continuously stressed during long-term use, reducing the risk of breakage of the brake arm; using the first cylinder as the power source for braking, the first cylinder can provide large thrust, strong braking effect, and high control accuracy, which can improve the braking efficiency of the strip winder.
