In connection with figures and embodiments, the present invention is explained in more detail below, so that the object, the technical solutions and the advantages of the present invention will become clearer. It goes without saying that the detailed embodiments described here serve only to explain the present invention, instead of limiting the present invention.

How out 1 to 2 results, the drawing table for artificial leather includes a work table 1 , a two-axis synchronous belt sliding table 2 , a lifting mechanism 3 , a feed mechanism 4th , a pressing mechanism 5 , a pull-flat mechanism 6th and a drive mechanism 7th . At the work table 1 is an opening 11 that allows leather to pass through. The feeding mechanism 4th is at one end of the work table 1 arranged and used to put on a leather roll. The leather is upon entering the opening 11 starting from the lowest area of the work table 1 on the top surface of the work table 1 laid out flat. The pressing mechanism 5 is on the lower surface of the work table 1 arranged to press one end of the leather tightly, thereby affecting the on the top surface of the work table 1 flat leather through the retraction mechanism 4th while drawing is prevented. The pull-flat mechanism 6th is slidable on the work table 1 arranged and the drive mechanism 7th is at the work table 1 arranged to the flattening mechanism 6th to drive for horizontal reciprocation. Leather is drawn in by means of the flat drawing mechanism using negative pressure and the drive mechanism 7th becomes the flattening mechanism 6th moved in a lateral direction to lay out the leather flat. The two-axis synchronous belt sliding table 2 is on the work table 1 arranged and the lifting mechanism 3 is on the two-axis synchronous belt sliding table 2 arranged. The pen can be attached to the lifting mechanism 3 and moves under the drive of the two-axis synchronous belt sliding table 2 in the horizontal plane. For areas that do not require drawing, the pen is lifted by the lifting mechanism 3 raised and thus moved away from the leather.

How out 1 to 4th results, includes the pull-flat mechanism 6th specifically a scaffolding 61 , a first guide rod 62 , a movable plate 63 , an electric cylinder 64 , a press wheel 65 , a guide wheel 66 , a first press plate 67 , a feather 68 and a pull-flat case 69 . The first guide bar 62 is on two sides of the work table 1 arranged. The scaffolding 61 is on the first guide rod 62 arranged and on the inner wall of two sides of the frame 61 is a first guide groove in the vertical direction 611 provided in the two ends of the movable plate 63 are slidably arranged. The electric cylinder 64 is on the top surface of the scaffolding 61 arranged and with the movable plate 63 connected. Powered by the electric cylinder 64 the moving plate moves 63 vertical. On the upper surface of the flat draw case 69 are a plurality of spaced apart second guide rods 691 intended. Usually the second guide rods 91 provided in numbers of at least two. It goes without saying that depending on the length of the flat drawn housing 69 the number of second guide bars 691 can be increased. On the moving plate 63 are the second guide rods 691 associated guide bores are provided in which the second guide rods 691 are slidably arranged. The first feather 68 is on the second guide rod 691 pushed open and located between the movable plate 63 and the flat draw case 69 . At the top of the second guide rod 691 a stop is provided to separate the movable plate 63 from the flat draw case 69 to prevent. On the lower surface of the flat draw case 69 a sunk vacuum chamber is provided, on the side wall of which a connection connected to a vacuum generator is provided 692 is provided. The press wheel 65 is rollable at the lower end of the left and right side walls of the flat draw housing 69 arranged and the guide wheel 66 can be rolled inside the vacuum chamber and between the two press wheels 65 arranged. The first press plate 67 is at one of the opening 11 facing side of the movable plate 63 arranged. The first pressing plate is preferably located in the lowermost area 67 a pressure bar made of silicone rubber is provided. Alternatively, the lowest area is the first press plate 67 immediately covered with a rubber layer. The toughness of the rubber layer protects the leather from being damaged by pressing and at the same time increases the friction against the leather.

The following is the flattening of the leather using the flattening mechanism 6th detailed. First, the required leather is taken from the opening 11 pulled out and then using the locking mechanism 5 one end of the leather attached. The extracted leather is placed on the work table 1 laid out flat and powered by the drive mechanism 7th the flattening mechanism moves 6th up to the opening. The other end of the leather is lifted diagonally upwards by a worker in the direction of one end. Powered by the electric cylinder 64 the pull-flat housing moves 69 downward. The leather adheres to the press wheel by means of the pressure of the vacuum chamber 65 and the guide wheel 66 , after which the leather through the electric cylinder 64 is raised slightly. Then the flattening mechanism 6th by the drive mechanism 7th pulled towards one end, the leather is now stretched flat under the action of the tensile force. Then the pull-flat housing moves 69 driven by the electric cylinder 64 down and after pressing the leather against the work table further in a lateral direction. After reaching one end, the movable plate moves 63 driven by the electric cylinder 64 further down and through the first press plate 67 one end of the leather is pressed tightly. This enables the leather to be pulled flat and pressed into place. This avoids wrinkles during the drawing process.

In one embodiment, as in 1 to 4th shown includes the drive mechanism 7th a servo motor 71 , a first lead screw 72 and a moving block 73 . The first lead screw 72 is rotatable on the lowest area of the work table 1 arranged and runs parallel to the first guide rod 62 . The moving block 73 is on the first lead screw 72 connected and with the scaffolding 61 connected. The servo motor 71 drives the moving block 73 to move to the flattening mechanism 6th to set in motion.

In one embodiment, as in 1 to 2 shown, includes the compression mechanism 5 in one embodiment a compressed air cylinder 51 and a second press plate 52 . On the lower surface of the work table 1 is a U-shaped enclosure protruding downwards around the opening 12 intended. On the inside of the two side walls of the enclosure 12 is a second guide groove 13 provided in the two ends of the second press plate 52 are slidably arranged. The compressed air cylinder 51 is on the lower surface of the work table 1 attached to the second press plate 52 to drive for horizontal reciprocation. Through the second press plate 52 the leather becomes firmly against the enclosure 12 pressed. Preferably the press plate is 52 covered with a rubber layer. The toughness of the rubber layer protects the leather from being damaged by pressing and at the same time increases the friction against leather.

How out 1 to 2 results, it is provided in one embodiment that the pressing mechanism also has a role 14th comprises, wherein the lower end of the second press plate 51 and the top right corner of the opening each with the roller 14th are provided. Through the role 14th the scratching of the surface of the leather as a result of friction is avoided.

One end of the swing arm 41 and one end of the support air cylinder 42 are each arranged at the upper end or the lower end of a table leg, while the other end of the pivot arm 41 at the other end of the support air cylinder 42 is hinged. On the swivel arm 41 is a recess to accommodate the support shaft 43 intended. The support shaft 43 is used to attach a leather roll and its two ends are built into the recess. When retracting the support air cylinder 42 the swivel arm rotates 41 downwards so that the recess is lowered, with which the leather roll is pushed between the two lifting mechanisms. The support shaft 43 is inserted in the middle of the leather roll and its two ends are inserted into the recess. The support air cylinder 42 is driven to the swivel arm 41 to turn upwards and thus lift the leather roll.

How out 5 results, it is provided in one embodiment that the lifting mechanism 3 a basic carrier 31 , a third guide rod 32 , a stepper motor 33 , a lifting block 34 and a second lead screw 35 includes.
