Description

Technical Field

[0001] This utility model belongs to the technical field of garment trimming devices, and particularly relates to a trimming device for knitted garments. Background Technology

[0002] Knitted garments are made by weaving yarn into loops using knitting needles and interlocking them. They have good elasticity, breathability, and softness, are comfortable to wear, and come in a variety of styles, such as T-shirts, sweaters, and sportswear.

[0003] For example, Chinese patent CN222251481U discloses a knitted garment trimming device, belonging to the field of garment processing technology. It includes a carrier plate, a driving mechanism connected to one side of the carrier plate, and a trimming mechanism located at the output end of the driving mechanism on the other side of the carrier plate. This invention features a collection component; an adsorption frame and a vacuum cleaner are placed inside the collection box, and a support block supports the adsorption frame. A moving wheel drives the collection box closer to the carrier plate. Magnetic blocks on the sidewalls of the collection box and the adsorption tank adhere and fix each other. The adsorption force generated by the vacuum cleaner enters the adsorption frame through the suction pipe. During the trimming process, debris falls into the adsorption frame under the action of the vacuum cleaner. A protective net prevents debris from falling into the suction pipe, ensuring proper collection and preventing blockage of the suction pipe. This facilitates the collection and handling of debris generated during the trimming process.

[0004] The aforementioned patent has the following problems:

[0005] The patented device has some drawbacks in use, such as: the device easily causes fabric wrinkles during the hemming process, resulting in an uneven garment surface after hemming; and the circular cutter of the device requires replacement with tools after long-term use, making it difficult to operate without the necessary tools, thus limiting the device's applicability. Therefore, we propose a hemming device for knitted garments. Utility Model Content

[0008] The housing is fixedly installed on the top of the base. Two first fixing plates and two second fixing plates are fixedly installed on the top of the base and on both sides of the housing. A raw material roller is rotatably installed between the two first fixing plates. A first motor is fixedly installed on one side of one of the second fixing plates. The output shaft of the first motor passes through one of the second fixing plates and is fixedly installed with a rotating shaft.

[0009] Two rotating columns are rotatably installed inside the housing. Two arc-shaped grooves are opened on each of the two rotating columns. A second motor is fixedly installed on both sides of the housing. The output shafts of the two second motors pass through the housing and are fixedly installed on the fixed columns. The two circular cutters are respectively inserted into the two fixed columns.

[0010] A drive assembly, located within the housing, is used to drive the two rotating columns to rise and fall.

[0011] Two sets of fixing components are located inside the housing and are used to fix the positions of the two circular cutters respectively.

[0012] In this technical solution, when it is necessary to trim the edges of knitted garments, the drive assembly can drive two rotating columns to move downwards. When both rubber sleeves are in close contact with the fabric, the first motor is started and drives the rotating shaft to rotate. The rotating shaft drives the fabric to move slowly in the direction of the rotating shaft. The fabric drives the two rotating columns to rotate through the two rubber sleeves. The two rubber sleeves can flatten the fabric and ensure that no wrinkles appear during trimming. At the same time, two second motors are started, and the two second motors drive the two fixed columns and two circular cutters to rotate. The two circular cutters can trim the edges of the fabric.

[0013] The disc can be removed using the fixed assembly, and then the circular cutter can be taken out. A new circular cutter can also be installed using the fixed assembly, and the operation is simple and requires no tools.

When both rubber sleeves are in close contact with the fabric, the first motor is activated and drives the rotating shaft to rotate. The rotating shaft drives the fabric to move slowly in the direction of the rotating shaft. The fabric drives the two rotating columns to rotate through the two rubber sleeves. The two rubber sleeves can flatten the fabric and ensure that no wrinkles appear during trimming. At the same time, two second motors are activated. The two second motors drive the two fixed columns and the two circular cutters to rotate. The two circular cutters can trim the edges of the fabric.

[0017] In the above technical solution, the fixing component further includes:

[0020] In this technical solution, when it is necessary to replace two circular cutters, the above operation can drive the two rotating columns to move upward, and then rotate the gear ring. The gear ring drives the several first gears meshing with it to rotate, and the several first gears drive the several second gears to rotate. The several second gears drive the several racks meshing with them to slide away from the fixed column, and the several racks drive the several rectangular blocks to slide. At the same time, several springs are compressed and contracted. After the several rectangular blocks are disengaged from the several limiting blocks, the disc can be taken out, and then the circular cutter can be taken out. The new circular cutter can be installed by reversing the above operation. The operation is simple and does not require the use of tools.

[0021] In the above technical solution, a fixing block is further fixedly installed on the gear ring, one end of the fixing block passes through the limiting groove and extends to the outside, and the fixing block is rotatably connected to the limiting groove.

[0022] In this technical solution, a fixed block is provided to facilitate the rotation of the gear ring by the operator.
