Description

Technical Field

[0001] The utility model belongs to the technical field of spinning machine drafting, and in particular relates to a roving drafting component for a spinning machine. Background Art

[0002] Drafting is a mechanical equipment used in the drafting and twisting process of yarn production. The yarn spun by the spinning machine has a certain linear density, strength, elongation and other physical properties after drafting and twisting. At present, the production process of coarse yarn requires the use of drafting components to perform drafting work.

[0003] However, the existing roving drafting assembly for spinning machines usually achieves roving drafting through the speed difference between the intermediate pulley and the lower ratchet, which makes it difficult for this type of roving drafting assembly to integrate the drafting of the roving and the cleaning of waste chips. As a result, a large amount of waste chips often fall off during the drafting process of the roving, which requires manual cleaning, causing a certain amount of labor consumption, and the waste chips affect the overall aesthetics of the device. Therefore, a roving drafting assembly for a spinning machine is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a roving drafting assembly for a spinning machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coarse yarn drafting assembly for a spinning machine, comprising a platform, a shell fixedly connected to one side of the platform, a connecting plate fixedly connected to the top of the platform, two bearings clamped in the connecting plate, rollers rotatably connected in both bearings, one end of one of the rollers fixedly connected to a motor, and the output shaft of the motor fixedly connected to one end of one of the rollers.

[0006] A stretching roller is fixedly connected to the outside of the roller, and a connecting shell is fixedly connected to the front of the two stretching rollers. Gears are fixedly connected to the outside of the two rollers, and the two gears are meshed. A toggle block is fixedly connected to the back of one of the gears, and a guide block is provided outside the toggle block. A connecting strip is fixedly connected above the guide block, and shovel edges are fixedly connected to both sides of the connecting strip, and the shovel edges are arranged above the platform.

[0007] As a preferred implementation, a bolt is threadedly connected to the top of the connection shell, and an arc-shaped positioning block is fixedly connected to the bottom end of the bolt.

[0008] As a preferred implementation, a telescopic rod is fixedly connected to one side of the guide block, and the telescopic rod is fixedly connected in the housing.

[0009] As a preferred implementation manner, a motor fixing block is fixedly connected to the outside of the motor, and one side of the motor fixing block is fixedly connected to one side of the platform.

[0010] As a preferred embodiment, two drop holes are provided in the platform, and two discharge ports are fixedly connected to the bottom of the platform, and the positions of the discharge ports correspond to the drop holes.

[0011] As a preferred embodiment, a baffle is slidably connected in the discharge port, and support legs are fixedly connected to the four corners of the bottom of the platform.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model is provided with rollers, gears, drafting rollers, a toggle block, a guide block and a shovel edge. When one of the rollers drives one of the gears to rotate, the other gear meshed with it can drive the other roller to rotate, so that the two rollers respectively drive the drafting rollers to rotate, so as to achieve the purpose of drafting the coarse yarn. At the same time, one of the gears can drive the toggle block to rotate synchronously, so that when the toggle block rotates in the guide block, it can squeeze the guide block to drive the connecting strip to move left and right repeatedly, so that the connecting strip drives the two shovel edges to push the waste chips on the platform into the two drop holes, and then this device can integrate the drafting of the coarse yarn and the cleaning of the waste chips, so that a large amount of waste chips falling in the process of drafting the coarse yarn does not need to be cleaned manually, thereby avoiding a certain amount of labor consumption and preventing the waste chips from affecting the overall aesthetics of the device.

[0014] The utility model is provided with a drop hole, a discharge port and a baffle. The drop hole allows the waste chips pushed by two shovel edges to have space to fall into the discharge port. At the same time, the discharge port allows the waste chips to have space to be discharged to prevent the waste chips from accumulating in the discharge port. The baffle allows the discharge port of the discharge port to have the function of opening or closing to prevent the waste chips from accidentally falling through the discharge port.
