Description

Technical Field

[0001] The utility model relates to the printing and dyeing industry, in particular to a high-efficiency cloth spreading device. Background Art

[0002] In the printing and dyeing industry, the raw material is a white cloth roll, which needs to be unrolled and laid out before it can be evenly dyed.

[0003] At present, a Chinese patent with the authorization announcement number CN209081070U discloses a cloth-making machine, wherein a swingable square swing frame is installed at the top of the frame, and a No. 1 cloth-making roller and a No. 2 cloth-making roller are installed from bottom to top on the swing frame, and the No. 1 cloth-making roller and the No. 2 cloth-making roller are arranged front and back, and a No. 3 cloth-making roller is installed on the frame, and the No. 3 cloth-making roller is connected to the No. 1 cloth-making roller through a transmission belt, and the No. 2 cloth-making roller is on top of the transmission belt, and a swing rod is connected to both sides of the swing frame, and a swing wheel is connected to each end of the two swing rods. The color grey cloth passes through the No. 3 cloth-making roller, the No. 2 cloth-making roller, and the No. 1 cloth-making roller from the top of the frame in turn, and is initially flattened by the swing of the swing frame, and the No. 1 cloth-making roller and the No. 2 cloth-making roller are arranged front and back, so that the grey cloth can be initially flattened better, and at the same time, the No. 2 cloth-making roller is on top of the transmission belt, which plays a role in tightening the transmission belt.

[0004] This cloth-moving machine has a simple structure, but during use, as the cloth passes between the No. 1 cloth-moving roller and the No. 2 cloth-moving roller and falls onto the transport trolley below, as the amount of cloth on the transport trolley increases, the distance the cloth falls will gradually become shorter. Therefore, the cloth will be arranged in a pyramid shape on the transport trolley, and workers are required to arrange the cloth in order to fully utilize the space on the transport trolley, affecting production efficiency. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a high-efficiency cloth spreading device to achieve the purpose of improving production efficiency.

[0007] To implement the above technical solution, the cloth is passed around the first conveyor roller and the second conveyor roller and then through the conduction groove, and finally through the channel between the first slide bar and the second slide bar. At the same time, the power structure drives the rocker arm to swing back and forth, and the rocker arm drives the slider to move back and forth along the length direction of the support rod through the linkage assembly. Since the swing amplitude of the rocker arm is kept constant, the stroke of the slider is kept constant, and the process of the cloth falling from the channel is vertical falling, so that the cloth in the channel has a uniform flat state, thereby eliminating the subsequent sorting process of workers, greatly improving production efficiency.

[0008] As a preferred solution of the utility model, the linkage assembly includes a sliding sleeve and a connecting rod. The connecting rod is fixed on the rocker arm and arranged along the length direction of the rocker arm. The outer wall of the sliding sleeve is rotatably connected to the outer wall of the slider. The end of the connecting rod away from the rocker arm is inserted into the sliding sleeve.

[0009] To implement the above technical solution, during the swinging process of the swing rod, the connecting rod contacts the inner wall of the slide groove and pushes the slider along the length direction of the support rod. At the same time, the connecting rod drives the sliding sleeve to rotate and slides along the sliding sleeve.

[0010] As a preferred solution of the utility model, the sliding block is provided with an adjusting structure for adjusting the distance between the first sliding rod and the second sliding rod.

[0011] By implementing the above technical solution and adjusting the setting of the structure, the distance between the first slide bar and the second slide bar can be adjusted to adapt to fabrics of different thicknesses, thereby improving practicality.

[0013] To implement the above technical solution, the slide is moved along the length direction of the slide groove, thereby adjusting the distance between the first slide rod and the second slide rod to adapt to the current thickness of the fabric, and then the locking bolt is tightened so that the locking bolt and the slider are pressed tightly, and the friction force generated realizes the positioning of the slide and the second slide rod.

[0014] As a preferred solution of the utility model, the outer walls of the first sliding rod and the second sliding rod are both sleeved with anti-slip layers, and the anti-slip layers are made of rubber.

[0015] By implementing the above technical solution, the anti-skid layer increases the friction between the first slide bar, the second slide bar and the fabric, so that the first slide bar and the second slide bar rotate more smoothly.

[0016] As a preferred solution of the utility model, the power structure includes a power motor, a first linkage wheel, and a second linkage wheel. The power motor is fixed on the frame, the first linkage wheel is coaxially fixed on the first conveying roller, and the second linkage wheel is coaxially fixed on the second conveying roller. The power motor drives the first linkage wheel and the second linkage wheel to rotate through a first belt.

[0017] To implement the above technical solution, the power motor is started, and the first interlocking wheel and the second interlocking wheel are driven to rotate synchronously and in the same direction through the first belt, so that the first conveying roller and the second conveying roller are rotated synchronously and in the same direction.

[0018] As a preferred solution of the utility model, the power structure also includes a reduction wheel, an L-shaped rod, and a connecting rod. The reduction wheel is rotatably connected to the frame, the reduction wheel is connected to the first linkage wheel through a second belt, one end of the L-shaped rod is fixed to the reduction wheel, one end of the connecting rod is hinged to the L-shaped rod, and the other end is hinged to the rocker arm.

[0019] To implement the above technical solution, the second belt drives the reduction wheel to rotate, the reduction wheel drives the L-shaped rod to rotate, and the L-shaped rod causes the swing rod to swing back and forth through the connecting rod. BRIEF DESCRIPTION OF THE DRAWINGS
