Description

Technical Field

[0001] The utility model belongs to the technical field of trouser leg cutting, and particularly relates to a trouser leg cutting device for the production of Western-style trousers. Background Technique

[0002] In daily dressing, the trousers purchased may not be of the right length for oneself, and there may be a section that is too long at the trouser leg, so it is necessary to cut the trouser leg into an appropriate length to achieve a better matching effect.

[0003] For example, the Chinese patent with the publication number CN217454037U discloses a trouser leg cutting device for the production of women's casual Western-style trousers, which relates to the field of clothing processing equipment and includes a bottom plate, a pressing mechanism, a locking mechanism, and a cutting mechanism; a pressing mechanism and a locking mechanism are provided on the bottom plate. The pressing mechanism includes two parallel strip-shaped plates, a hinge, and a hinge support. The hinge support is fixedly installed on the bottom plate, and the hinge support is respectively hinged to the rear ends of the two strip-shaped plates through the hinge. The top surfaces of the two strip-shaped plates are provided with chutes distributed along the length direction of the strip-shaped plates; the locking mechanism includes a track and a limiting block. The track is located on the bottom plate at the front end of the strip-shaped plate, and the limiting block is located above the track and is movably connected to the track; a cutting mechanism is provided on the strip-shaped plate. This device presses the trouser leg through the pressing mechanism, locks the pressing mechanism through the locking mechanism to prevent loosening during cutting, and cuts the pressed trouser leg through the cutting mechanism.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use. For example, when the device is used for the trouser leg and for cutting the trouser leg, manual operations by personnel are required, which is rather troublesome, time-consuming, and laborious. Moreover, when disassembling or installing the cutting knife of this device, fastening bolts and auxiliary tools are needed, which is rather inconvenient. In view of this, we propose a trouser leg cutting device for the production of Western-style trousers. Content of the Utility Model

[0006] The purpose of the utility model is to provide a trouser leg cutting device for the production of Western-style trousers to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a trouser leg cutting device for the production of Western-style trousers, including:

[0008] Workbench, two cylinders one are fixedly installed at the bottom of the workbench, the output shafts of the two cylinders one both penetrate through the bottom of the workbench and are fixedly installed with the same U-shaped plate, two pressing plates are fixedly installed inside the U-shaped plate, two sliding grooves are formed in the U-shaped plate, sliders are slidably installed in the two sliding grooves, the tops of the two sliders are fixedly installed with the same fixing plate, a cylinder two is fixedly installed at the top of the fixing plate, the output shaft of the cylinder two penetrates through the fixing plate and is fixedly installed with a connecting plate, two grooves are formed in the bottom of the connecting plate, a second threaded rod is rotatably installed in the groove, a U-shaped block is slidably installed on the second threaded rod in the groove, two mounting blocks are fixedly installed at the bottom of the connecting plate, a cutting knife is inserted and installed in the mounting block, one end of the U-shaped block penetrates through one side of the mounting block and extends into the cutting knife, and a cutting groove is formed in the workbench and directly below the U-shaped plate;

[0009] Driving assembly, the driving assembly is located in one of the sliding grooves and is used to drive the displacement of one of the sliders.

[0010] In this technical solution, during use, the staff first draws a cutting line at the trouser leg. Subsequently, place the trouser leg on the workbench and below the U-shaped plate, and make the cutting line directly above the cutting groove. Then, start the two cylinders one, so that the output shafts of the two cylinders one drive the U-shaped plate to move downward until the rubber pad at the bottom of the U-shaped plate contacts the trouser leg and presses it on the workbench. At this time, the two pressing plates will also press the trouser leg, and the cutting line on the trouser leg will be located between the two pressing plates, ensuring that the trouser leg can be firmly fixed when cutting the trouser leg, making the cutting effect better. Then, the staff starts the cylinder two, so that the output shaft of the cylinder two drives the connecting plate to move downward. The connecting plate will drive the two mounting blocks and the two cutting knives to move downward until the lower end of the cutting knife enters the cutting groove between the two pressing plates. Subsequently, through the provided driving assembly, the driving assembly drives the displacement of one of the sliders. Then, the slider will drive the fixing plate to move, and the fixing plate will drive the other slider to move. Then, the two cutting knives will move in the direction of the trouser leg. During the movement, one of the cutting knives will cut the trouser leg. After cutting, turn off the servo motor, so that the output shafts of the two cylinders one drive the U-shaped plate to move upward, so that the U-shaped plate no longer presses the trouser leg, and then take it out;

[0011] When disassembling the cutting knife, the staff rotates the handle on the second threaded rod in the forward direction by hand and drives the second threaded rod to rotate. Under the action of the thread, the second threaded rod will drive the U-shaped block to displace, so that one end of the U-shaped block moves out of the cutting knife. At this time, the cutting knife will be released from the limit and can be disassembled and replaced. During installation, insert the upper end of the cutting knife into the installation block from bottom to top. Subsequently, the staff rotates the handle on the second threaded rod in the reverse direction by hand and drives the second threaded rod to rotate. Under the action of the thread, the second threaded rod will drive the U-shaped block to displace. At this time, one end of the U-shaped block will move within the installation block and make one end of the U-shaped block insert into the cutting knife, thereby fixing it within the installation block.

One side of the U-shaped plate is fixedly installed with a servo motor, and the output shaft of the servo motor penetrates through one side of the U-shaped plate and extends into one of the sliding grooves and is coaxially connected to one end of the first threaded rod.

[0014] In this technical solution, start the servo motor to drive the first threaded rod to rotate by the output shaft of the servo motor. Under the action of the thread, the first threaded rod will drive one of the sliders to displace; ensure that one of the sliders can be driven to displace.

[0015] In the above technical solution, further, one of the sliders is threadedly connected to the first threaded rod, and the output shaft of the servo motor is rotatably connected to one side of the U-shaped plate and one of the sliding grooves.

[0016] In this technical solution, under the action of the thread, when the first threaded rod rotates, it will drive one of the sliders to displace; ensure that the servo motor can operate normally.

[0017] In the above technical solution, further, a round rod is fixedly installed in the other sliding groove, and one end of the round rod penetrates through the other slider, and the slider is slidably connected to the round rod.

[0018] In this technical solution, during cutting, the other slider will slide above the round rod to ensure stability during displacement.

[0019] In the above technical solution, further, the two pressing plates are located on both sides of the cutting groove, and the distance between the two pressing plates is equal to the width of the cutting groove. The width of the cutting knife is equal to the width of the cutting groove. One end of the second threaded rod penetrates through one side of the groove and extends to the outside and is fixedly installed with a handle.

[0020] In this technical solution, it is ensured that the cutting knife can enter the cutting groove so as to better cut the trouser legs; it is guaranteed that personnel can rotate the second threaded rod through the handle, which is relatively convenient.
