Description

Technical Field

[0001] This utility model relates to the field of leather cutting technology, and more specifically to a cutting device for automotive seat leather. Background Technology

[0002] Car seats are an essential part of a car. To improve the comfort and aesthetics of car seats, leather is used to cover the surface of the car seats. During the leather processing, the rolled leather needs to be cut into small pieces and then further processed according to the specific shape of the seat.

[0003] When cutting and processing rolled leather, the leather is usually laid on the cutting table first, then flattened and pressed to fix it, and then cut with a cutter. However, when the ambient temperature is low, the leather is harder. If the leather is directly flattened and pressed to fix it, it is difficult to flatten and the flattening effect is not thorough, which makes it difficult to meet the purpose of subsequent flat cutting and processing of the leather.

[0004] In view of this, the present invention proposes a cutting device for automotive seat leather. Utility Model Content

[0007] The flat support assembly includes two mounting slide rods symmetrically slidably connected to the left and right ends of the upper surface of the lifting plate. A connecting frame is fixedly installed at the bottom end of the mounting slide rod. A support spring is sleeved on the surface of the mounting slide rod to press the connecting frame downward and support it. A flat support roller is rotatably connected to the inner wall of the connecting frame. A servo motor that drives the flat support roller to rotate is fixedly installed on the front of the connecting frame.

[0008] The heating and cutting assembly includes a raised platform fixedly installed at the bottom of the lifting plate. A cutter is fixedly installed at the bottom of the raised platform. An air duct extending to the bottom side is opened inside the raised platform. A hot air fan is embedded on the surface of the lifting plate, and the air outlet of the hot air fan faces the inside of the air duct.

[0009] As a further description of the above technical solution: the surface of the cutting table is provided with a knife groove, which runs vertically through the table and corresponds to the position of the cutting blade; by setting the knife groove, the cutting blade can be avoided, thereby achieving the purpose of protecting the cutting blade.

[0010] As a further description of the above technical solution: the driving direction of the servo motor on the left is clockwise, and the driving direction of the servo motor on the right is counterclockwise.

[0011] As a further description of the above technical solution: the surface of the flattening roller is symmetrically provided with spiral patterns for flattening the leather to the front and back sides, and the spiral patterns on the left and right flattening roller surfaces are in opposite directions; by setting the spiral patterns, the leather can be flattened to the front and back sides during the rotation of the flattening roller, thereby further improving the flattening effect of the leather.

[0012] As a further description of the above technical solution: a first balance slide rod is fixedly installed on the surface of the lifting plate, and the first balance slide rod is slidably connected to the top frame; by setting the first balance slide rod, the movement path of the lifting plate can be limited, and the purpose of preventing torsion protection of the extension and retraction end of the hydraulic rod can be achieved.

[0013] As a further description of the above technical solution: the bottom end of the support spring abuts against the top of the connecting frame, and the top end of the support spring abuts against the bottom end of the lifting plate.

[0014] As a further description of the above technical solution: a second balance slide bar is fixedly installed on the surface of the connecting frame, and the second balance slide bar is slidably connected to the lifting plate; by setting the second balance slide bar, the stability of the connecting frame when it moves can be ensured and the connecting frame can be prevented from shaking.

[0015] As a further description of the above technical solution: a collection box is fixedly installed at the bottom of the cutting table, and a collection drawer is inserted into the front of the collection box; by setting up the collection box, cutting debris can fall through the blade groove onto the surface of the collection drawer, thereby achieving the purpose of collecting cutting debris and facilitating the maintenance of a clean processing environment.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with existing technologies, leather raw material rolls are conveyed to the cutting table surface via an external conveyor belt. The lifting plate moves down by extending the hydraulic rod, and two supporting rollers pre-contact the leather. Two servo motors drive the two supporting rollers to rotate, which can achieve the effect of supporting the leather horizontally. At the same time, a hot air blower blows hot air onto the surface of the leather, which can achieve the effect of heating and softening the leather, ensuring the effect of supporting. Then, it is further compressed by the support spring, and the cutter contacts the leather to cut the leather into blocks to meet the leather requirements of subsequent automotive seat processing.
