Description

Technical Field

[0001] The utility model relates to the technical field of garment processing, in particular to a tunic cutting machine. Background Art

[0002] The gabi is a traditional Chinese handicraft material, usually used to make cloth shoes, hats, bags and other items. It is a stiff cloth made of multiple layers of cotton or linen cloth bonded together with a paste made of flour, pressed and dried. The gabi cutting machine is a mechanical device specially used for cutting gabi. This machine is usually used in a mass production environment to improve cutting efficiency and ensure cutting accuracy.

[0003] At present, when the existing tunic cutting machine is cutting the tunic, it is necessary to first pull out the workbench of the machine, then place the tunic flatly on the workbench of the machine, then place the mold at a specified position of the tunic, and then push the workbench of the machine back, and press the mold down by the machine to cut the tunic. After completing one cutting, the workbench of the machine is pulled out again, and then the mold is replaced for the next cutting. The cutting operation of this tunic cutting machine is relatively cumbersome, resulting in low cutting efficiency.

[0004] In order to solve the above problems, we propose a tunic cutting machine, which can perform automatic material feeding and position change operations to improve the cutting efficiency. Utility Model Content

[0005] In order to overcome the disadvantages of the existing garb cutting machine that the operation is complicated during cutting, resulting in low cutting efficiency, the utility model provides a garb cutting machine, which can perform automatic material feeding and position change operations to improve the cutting efficiency.

[0006] The technical solution is as follows: a machine for cutting tunics, comprising a mounting frame, a hydraulic cylinder fixedly connected to the mounting frame, a cutting template fixedly connected to the telescopic end of the hydraulic cylinder, a placing platform slidably connected to the mounting frame, and a driving motor fixedly connected to the mounting frame, a threaded rod fixedly connected to the output shaft of the driving motor, the threaded rod being rotatably connected to the mounting frame, the threaded rod being threadedly connected to the placing platform, a traction assembly being provided on the placing platform, the traction assembly being used to traction the tunic and place it on the placing platform, and a pushing assembly being provided on the mounting frame for pushing the tunic flat.

[0007] Preferably, feet are fixedly connected to the four corners of the bottom end of the mounting frame.

[0008] Preferably, the traction assembly includes a laterally symmetrical electric guide rail, which is fixedly connected to the placement platform, a lower pressure plate is slidably connected between the laterally symmetrical electric guide rails, an upper pressure plate is slidably connected to the lower pressure plate, and a left-right symmetrical elastic member is connected between the upper and lower pressure plates.

[0009] Preferably, a groove is provided in the middle of the upper pressing plate to facilitate lifting.

[0010] Preferably, a rubber pad is fixedly connected to one side of the upper pressing plate and the lower pressing plate where they are close to each other for anti-slip purposes.

[0011] Preferably, the push-flattening assembly includes a transversely symmetrical mounting block, which is fixedly connected to the mounting frame, a rotating rod is rotatably connected to the mounting block, a torsion spring is connected between the rotating rod and the adjacent mounting block, and a push-flattening roller is rotatably connected between the rotating rods.

[0012] The beneficial effect of the utility model is that the lower pressing plate and the upper pressing plate clamp one end of the tunic, and then pull the tunic backward and place it on the placing platform without manual handling. After the tunic is placed, the hydraulic cylinder extends to drive the cutting template downward to carry out cutting. After one cutting is completed, the driving motor controls the threaded rod to rotate to drive the placing platform to move backward, and then automatically drives the tunic to move backward for change of position, so as to carry out the next cutting. When the tunic moves backward for change of position, the flattening roller rotates to push the tunic flat, avoiding the tunic wrinkles from affecting the cutting effect. In this way, operations such as material discharge and change of position can be carried out automatically without manual operation, and it is more convenient to use.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Embodiment 1: A trouser cutting machine, such as Figure 1-Figure 7 As shown, it includes a mounting frame 1, a hydraulic cylinder 2, a cutting template 3, a placement platform 4, a driving motor 5, a threaded rod 6, a traction assembly and a push-flattening assembly. The four corners of the lower side of the mounting frame 1 are fixedly connected with feet, the upper part of the mounting frame 1 is fixedly connected with a hydraulic cylinder 2, the telescopic end of the hydraulic cylinder 2 is fixedly connected with the cutting template 3, the lower part of the mounting frame 1 is slidably connected with the placement platform 4, the front side of the lower part of the mounting frame 1 is fixedly connected with a driving motor 5, the output shaft of the driving motor 5 is fixedly connected with a threaded rod 6, the rear end of the threaded rod 6 is rotatably connected to the rear part of the mounting frame 1, the threaded rod 6 is threadedly connected to the placement platform 4, a traction assembly is provided on the placement platform 4, the traction assembly is used to pull the jacket and place it on the placement platform 4, and a push-flattening assembly for pushing the jacket flat is provided on the mounting frame 1.

[0023] When using the device, the staff uses the traction component to pull the jacket backward and place it on the placement platform 4. After the jacket is placed, the staff controls the hydraulic cylinder 2 to extend and drive the cutting template 3 to move downward to cut the jacket. After completing one cutting, the staff controls the hydraulic cylinder 2 to shorten and drive the cutting template 3 to move upward and reset. At this time, the staff controls the driving motor 5 to operate, and the output shaft of the driving motor 5 rotates to drive the threaded rod 6 to rotate. The threaded rod 6 rotates to drive the placement platform 4 to slide backward. The placement platform 4 slides backward to drive the jacket to move backward for replacement, and the jacket moves backward. When the tunic is cut, the flattening assembly can flatten the tunic to prevent wrinkles in the tunic from affecting the cutting effect. After the tunic moves backward, the staff controls the hydraulic cylinder 2 to extend and drive the cutting template 3 to move downward for cutting again. When the cutting of the entire tunic is completed, the staff controls the output shaft of the driving motor 5 to reverse, and the reversed output shaft of the driving motor 5 drives the threaded rod 6 to reverse, and the reversed threaded rod 6 drives the placement platform 4 to slide forward and reset. The staff can remove the cut tunic from the placement platform 4. In this way, operations such as material discharge and position change can be performed automatically without manual operation, which is more convenient to use.

[0024] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the traction assembly includes an electric guide rail 7, a lower pressure plate 8, an upper pressure plate 9 and an elastic member 10. The electric guide rails 7 are fixedly connected on both sides of the placement platform 4. The lower pressure plate 8 is slidably connected between the left and right electric guide rails 7. The upper pressure plate 9 is slidably connected to the lower pressure plate 8. A groove is provided in the middle of the upper pressure plate 9 for easy lifting. A rubber pad is fixedly connected to the side where the upper pressure plate 9 and the lower pressure plate 8 are close to each other for anti-slip. A left-right symmetrical elastic member 10 is connected between the upper pressure plate 9 and the lower pressure plate 8.

[0025] When using this device, the staff pulls the upper pressing plate 9 to slide upward, the elastic member 10 is deformed, and after the upper pressing plate 9 slides upward and opens, the staff puts one end of the jacket between the lower pressing plate 8 and the upper pressing plate 9. After the jacket is placed, the staff releases the upper pressing plate 9. Under the action of the resetting of the elastic member 10, the upper pressing plate 9 slides downward and resets to cooperate with the lower pressing plate 8, thereby fixing one end of the jacket. Then the staff drives the lower pressing plate 8 to slide backward through the electric guide rail 7, and the lower pressing plate 8 slides backward to drive the upper pressing plate 9 to move backward, thereby pulling the jacket backward, pulling the jacket backward and placing it on the placement platform 4 for cutting. When the cutting is completed, the staff drives the lower pressing plate 8 to slide forward and reset through the electric guide rail 7, and the upper pressing plate 9 moves forward and resets accordingly. In this way, the jacket can be automatically pulled backward and placed on the placement platform 4 without manual handling.

[0026] like Figure 1 , Figure 6 and Figure 7 As shown, the flattening assembly includes a flattening roller 11, a rotating rod 12, a torsion spring 13 and a mounting block 14. The upper front side of the mounting frame 1 is fixedly connected to a left-right symmetrical mounting block 14, the mounting block 14 is rotatably connected to the rotating rod 12, the torsion spring 13 is connected between the rotating rod 12 and the adjacent mounting block 14, and the flattening roller 11 is rotatably connected between the left and right rotating rods 12.

[0027] When using the device, when the lower pressing plate 8 and the upper pressing plate 9 are driven to move backward, the staff first controls the rotating rod 12 to rotate upward, the torsion spring 13 is deformed, the rotating rod 12 rotates upward to drive the flattening roller 11 to lift upward, and after the lower pressing plate 8 and the upper pressing plate 9 have placed the tunic, the staff releases the rotating rod 12, and under the action of the torsion spring 13 resetting, the rotating rod 12 rotates downward and drives the flattening roller 11 to move downward and press the tunic. When cutting, when the placing platform 4 drives the tunic to move backward for changing position, the flattening roller 11 can rotate to push the tunic flat to prevent the tunic wrinkles from affecting the cutting effect.
