Description

Technical Field

[0001] The present application belongs to the technical field of cloth processing equipment, and in particular, relates to an automatic cloth stretching machine. Background Art

[0002] In the clothing production industry, cloth pulling and cloth cutting play a vital role. Only regular pieces can sew clothes that meet the specifications. If the pieces are not regular, even the best sewing machines and the best sewing workers can hardly sew high-quality clothes. Cloth pulling is the first process of clothing making, and the quality of cloth pulling determines the quality of the entire production. At present, industrial cloth pulling and cloth spreading on the market mainly rely on manual handling of cloth rolls. The cloth is pulled around the rollers manually, and then cut manually at the designated fixed points, and then the cloth is manually flattened with tools. However, this is not only inefficient, but also requires a large number of workers to work, and the human resource cost is high. Summary of the invention

[0003] The purpose of this application is to provide an automatic cloth-stretching machine that can solve the above-mentioned problems.

[0004] The purpose of this application is to provide an automatic cloth-pulling machine, comprising:

[0005] frame;

[0006] A transport device, which is arranged on the frame and is used to transport the fabric roll;

[0007] A cloth pulling device, which is arranged on the frame and is used to stretch, flatten and cut the cloth;

[0008] It also includes a cloth clamping device, which is arranged on the frame and located on the side of the transporting device close to the cloth pulling device. The cloth clamping device is used to receive the transported cloth roll and clamp the cloth on the cloth roll to the cloth pulling device.

[0009] By adopting the above-mentioned automatic cloth-pulling machine, through the coordinated use of the conveying device, the cloth clamping device and the cloth-pulling device, the cloth roll can be automatically transported, and the cloth can be stretched and flattened, and finally the cloth can be cut. The corresponding mechanism replaces the staff, which not only reduces the workload of the staff, but also effectively reduces the labor cost. During processing, the staff places the cloth roll on the conveying device, and the conveying device transports the cloth roll to the cloth-pulling device. At this time, the cloth clamping device starts and fixes the cloth head on the cloth roll on the cloth-pulling device. The cloth-pulling device stretches the cloth, and finally cuts the cloth to complete the processing of the cloth.

[0010] Furthermore, the transport device comprises:

[0011] A lifting mechanism, the lifting mechanism comprising a supporting frame, a conveyor belt arranged on the supporting frame, and a first driver for driving the conveyor belt to operate;

[0012] The turning mechanism comprises a turning bucket and a second driver for driving the turning bucket to rotate, wherein one end of the turning bucket is hinged to the supporting frame;

[0013] Wherein, a plurality of strip-shaped protrusions are evenly arranged on the conveyor belt.

[0014] The fabric roll is placed on the tipping bucket, and the tipping bucket can be adjusted within 90° around the hinge point through the second driver. The fabric roll in the tipping bucket is moved to the conveyor belt by adjusting the angle. The conveyor belt consists of a horizontal section and an inclined section. The setting of the horizontal section can prevent the fabric in the tipping bucket from directly contacting the inclined section and falling, so that the fabric roll can be safely lifted. The setting of the inclined section can transport the fabric roll at a low place to a high place. At the same time, U-shaped raising protrusions are evenly arranged on the conveyor belt. The fabric can be fixed between the two strip-shaped protrusions, which play a supporting role when the fabric is lifted to prevent the fabric roll from falling.

[0015] Further: the cloth pulling device comprises:

[0016] A workbench, arranged on the frame;

[0017] A cloth guide seat is arranged on the workbench and can move on the workbench;

[0018] A cloth pressing mechanism is arranged on the cloth guide seat and is used to fix the cloth;

[0019] A cutting mechanism is arranged on the cloth guide seat and is used to cut the fixed cloth;

[0020] Among them, the workbench is also provided with a first driving mechanism for driving the cloth guide seat to move. The first driving mechanism includes a first screw arranged at the bottom of the workbench, a first motor drivingly connected to the first screw, and a first slider arranged on the first screw. The first slider is connected to the cloth guide seat.

[0021] When the cloth roll is transported to the cloth pulling device through the lifting mechanism, the cloth clamping device will start to fix the cloth head on the cloth roll on the cloth pulling device. After the cloth head is fixed, the first driving mechanism drives the cloth guide seat to move, moves the cloth guide seat to the edge of the workbench, and fixes the cloth head to the edge of the workbench. Then the first driving mechanism drives the cloth guide seat to return along the workbench. During the return process of the cloth guide seat, the cloth is stretched, and then the cutting mechanism cuts the stretched cloth.

[0022] Furthermore, the cloth pressing mechanism comprises:

[0023] a first cloth pressing structure, which is arranged on the cloth guiding seat and comprises a cloth guiding roller, a third driver for driving the cloth guiding roller, a first guide roller arranged on one side of the cloth guiding roller, a second guide roller arranged on the other side of the cloth guiding roller, and a pressing roller arranged between the second guide roller and the cloth guiding roller;

[0024] A second cloth pressing structure, which is arranged at one end of the workbench away from the handling device, and comprises a pressing rod and a first cylinder driving the pressing rod to move up and down;

[0025] There are multiple first guide rollers, and the multiple first guide rollers are arranged on one side of the cloth guiding seat close to the lifting mechanism.

[0026] Before cutting, the first cloth pressing structure and the second cloth pressing structure need to be used together to fix the cloth. Under the action of the cloth clamping device, the cloth is led out from the cloth roll, passes through the first guide roller, the cloth guide roller and the second guide roller in sequence, and is finally fixed by the pressing roller to prevent the cloth from falling off. After the pressing roller fixes the cloth, the cloth guide seat moves to the side of the second cloth pressing structure, the first cylinder starts to lift the pressing rod, and when the end of the cloth moves to the bottom of the pressing rod, the first cylinder drives the pressing rod to move downward, and the pressing rod presses the cloth. At this time, the cloth guide seat returns to its original position along the workbench. At this time, the cloth will be stretched, which is convenient for subsequent cutting.

[0027] Furthermore, the cutting mechanism includes a support frame, which is arranged on the cloth guide seat, and a sliding rod is arranged on the support frame, and a movable knife seat is arranged on the sliding rod, and a cutting knife is arranged at the bottom of the movable knife seat.

[0028] After the second cloth pressing structure fixes the cloth, the cloth guide seat will gradually move away from the second cloth pressing structure along the workbench. When it moves to a suitable position, the cloth guide seat stops. At this time, the movable knife seat on the sliding rod starts, driving the cutting knife to move along the sliding rod to cut the cloth, thus completing the cloth cutting work. This saves manpower and is quick and efficient. It moves along the sliding rod during cutting, and the cutting is more precise.

[0029] Furthermore, the cloth clamping device comprises:

[0030] A fixed frame, the fixed frame is movably arranged on the workbench;

[0031] A rotating rod is rotatably arranged on the fixing frame, and a fourth driver for driving the rotating rod to rotate is also arranged on the fixing frame;

[0032] The cloth clamping structure comprises a clamping rod symmetrically arranged on the rotating rod, the clamping rod comprises a first rod body and a second rod body hinged to each other, one end of the first rod body is mounted on the clamping rod, and a second cylinder is hingedly connected to the first rod body, and an output shaft of the second cylinder is hingedly connected to the second rod body;

[0033] Wherein, a clamping claw is arranged on one end of the second rod body away from the first rod body, and the clamping claw is used for clamping cloth.

[0034] When fixing the cloth, it is necessary to first pull the cloth head on the cloth roll onto the first cloth pressing structure. During pulling, the fourth driver starts and adjusts the angle of the rotating rod. During pulling, the angle between the clamping rod and the fixed frame gradually becomes smaller. When it moves to a suitable position, the second cylinder starts. When the output shaft of the second cylinder is pushed out, the angle between the first rod body and the second rod body gradually becomes larger. When the output shaft of the second cylinder is retracted, the angle between the first rod body and the second rod body gradually becomes smaller, and cooperates with the angle adjustment of the rotating rod to realize the position change of the clamping claw, which can better clamp the cloth head and improve the clamping efficiency. After clamping the cloth head, the fixed frame moves and pulls the cloth head to the first cloth pressing structure during the movement, completing the pulling of the cloth, which is convenient for the subsequent fixing and cutting of the cloth.

[0035] Furthermore, the cloth clamping device also includes a receiving seat arranged on the cloth guiding seat, the receiving seat is composed of two limit baffles and a plurality of round tubes arranged between the two limit baffles, and the receiving seat is used to receive the cloth roll transported by the lifting mechanism.

[0036] The receiving seat composed of multiple round tubes and limit baffles can play a certain protective role for the fabric roll when storing the fabric roll. The setting of the round tubes can prevent the fabric roll from being damaged during reception, and the setting of the limit baffles can play a blocking role to prevent the fabric roll from falling outside the receiving seat.

[0037] Furthermore, a second driving mechanism for driving the fixed frame to move is also provided at the bottom of the workbench. The second driving mechanism includes a second lead screw arranged at the bottom of the workbench, a second motor drivingly connected to the second lead screw, and a second slider arranged on the second lead screw. The second slider is connected to the fixed frame.

[0038] In the process of pulling the cloth head to the first cloth pressing structure, the fixed frame needs to be moved. The cloth guide seat will not move during the traction process. Driven by the second motor, the second slider moves on the second screw rod and drives the fixed frame to move, thereby driving the cloth clamping device to move, and then driving the cloth head to move to complete the traction work. Among them, the inner diameter of the fixed frame is larger than the outer diameter of the cloth guide seat, and the movement of the two will not affect each other to avoid collision.

[0039] The beneficial effects of this application are:

[0040] 1. The above-mentioned automatic cloth-pulling machine can automatically transport the cloth roll, stretch and flatten the cloth, and finally cut the cloth through the coordinated use of the conveying device, the cloth clamping device and the cloth-pulling device. The corresponding mechanism replaces the staff, which not only reduces the workload of the staff, but also effectively reduces the labor cost;

[0041] 2. After the second cloth pressing structure fixes the cloth, the cloth guide seat will gradually move away from the second cloth pressing structure along the workbench. When it moves to a suitable position, the cloth guide seat stops. At this time, the moving knife seat on the slide rod starts, driving the cutting knife to move along the slide rod to cut the cloth, thus completing the cloth cutting work, saving manpower and being fast and efficient. When cutting, it moves along the slide rod, and the cutting is more accurate.

[0042] 3. During traction, the fourth driver starts and adjusts the angle of the rotating rod. During traction, the second cylinder starts. When the output shaft of the second cylinder is pushed out, the angle between the first rod body and the second rod body gradually increases. When the output shaft of the second cylinder is retracted, the angle between the first rod body and the second rod body gradually decreases. The angle adjustment of the rotating rod is combined with the position change of the clamping claw to better clamp the fabric head and improve the clamping efficiency. After clamping the fabric head, the fixed frame moves and pulls the fabric head to the first cloth pressing structure during the movement to complete the traction of the fabric, which is convenient for the subsequent fixation and cutting of the fabric.
