[0014] Beneficial effects
[0015] This invention provides a length measuring device for sofa leather production. Compared with the prior art, it has the following advantages:
[0016] This sofa leather production length measuring device, through the inclusion of limiting and adjusting components within the device, allows a first motor to drive a first bidirectional screw, two sets of clamping frames, and a sliding rod in a coordinated manner. The clamping frames move the sofa leather to the center of the connecting plate. A cylinder assembly, in conjunction with the clamping strip, limits the movement of the sofa leather from the upper side, thus correcting deviations and improving subsequent docking accuracy. The sofa leather is positioned between two sets of L-shaped plates. Through the coordinated movement of a height adjustment component, a second motor, a pulley assembly, two sets of second bidirectional screws, two sets of sliders, and the L-shaped plates, the width and thickness of the sofa leather are limited and clamped.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0032] In use, the user transfers the produced sofa leather to the upper middle of the connecting plate 2 via an external feeding device. The first motor 33 drives the first bidirectional screw 34 to rotate, and the first bidirectional screw 34 drives the two sets of clamping frames 35 to move along the slide bar 36 towards both sides of the sofa leather. After the clamping frames 35 move the sofa leather to the middle of the connecting plate 2, the height of the clamping strip 32 is adjusted by the cylinder assembly 31 so that the clamping strip 32 fits against the upper side of the sofa leather, thereby limiting the width and thickness of the sofa leather. The horizontal position of the sofa leather is finely adjusted so that the sofa leather is located between the two sets of L-shaped plates 56. The second motor 53 and the pulley assembly 54 cooperate to drive the two sets of second bidirectional screws 52 to rotate. The two sets of second bidirectional screws 52 adjust the distance between the two sets of sliders 55, L-shaped plates 56 and unidirectional screws 574 so that the two L-shaped plates 56 on both sides fit against the sides of the sofa leather.
[0033] The bottom of the sofa leather fits into the upper part of the slider 55. The position of the sofa leather is finely adjusted so that the back side of the sofa leather contacts the back side of the L-shaped plate 56. The third motor 571, the cross shaft 572, the two sets of sleeves 573, and the bevel gear assembly 575 work together to drive the two sets of one-way screws 574 to rotate. The rotating one-way screws 574 drive the clamping plate 58 to slide vertically along the L-shaped plate 56, so that the L-shaped plate 56 clamps the sofa leather on the slider 55. The electric slide rail 4 drives the adjusting component 5 to move horizontally. The adjusting component 5 pulls the sofa leather to move. After the end of the sofa leather moves to the underside of the clamping strip 32, the cylinder assembly 31 works with the clamping strip 32 to clamp the sofa leather. The length of the sofa leather is calculated by the displacement of the adjusting component 5.
