A first guide rail 34 and a second guide rail 35 which are parallel to each other are fixed on the top surface of the vibration feeding plate 2 along the length direction, a guide channel is formed between the first guide rail 34 and the second guide rail 35, the input ends (the ends connected with the transition rail 26) of the first guide rail 34 and the second guide rail 35 are in a horn mouth shape which is separated from each other, a first compression roller 36 and a second compression roller 37 are arranged above the vibration feeding plate 2, the first compression roller 36 is connected with a first driving mechanism which can enable the first compression roller to abut against or be far away from the top surface of the vibration feeding plate 2, the second compression roller 37 is connected with a second driving mechanism which can enable the second compression roller to abut against or be far away from the top surface of the vibration feeding plate 2, when the first compression roller 36 abuts against the vibration feeding plate 2, the first compression roller 36 is close to one side of the pull ring seat hole 4 and is positioned between the first guide rail 34 and the second guide rail 35, and when the second compression roller 37 abuts against the vibration feeding plate 2, the second compression roller 37, spacing 3 just can fix a position the setting at the top surface of vibration pay-off board 2 along the length direction slidable of vibration pay-off board 2, and dovetail groove 38 has been seted up along its length direction to the top surface of vibration pay-off board 2, and the bottom of spacing 3 is fixed with the forked tail slider, and the forked tail slider gomphosis is in dovetail groove 38, and the screw that link up its bottom surface is seted up to the top surface of spacing 3, and the spiro union has locking screw 39 in the screw. The leather pull-tab on the transition track 26 enters the vibration feeding plate 2, enters the guide channel along the horn mouths of the first guide track 34 and the second guide track 35, one end of the leather pull-tab penetrates through the square hole of the pull ring and is abutted to the limiting strip 3, then the first driving mechanism drives the first pressing roller 36 to be abutted to the top surface of the leather pull-tab, the second driving mechanism drives the second pressing roller 37 to be abutted to the top surface of the leather pull-tab, when the clamping mechanism pulls the pull ring in the clamping channel downwards, the leather pull-tab is limited by the first guide track 34 and the second guide track 35 on the one hand, so that the left side and the right side of the leather pull-tab can be aligned after being folded, and on the other hand, the end of the leather pull-tab can be prevented from being tilted to be separated from the guide channel due to the abutting effect of the first pressing roller 36 and the second pressing roller 37, the position of the. In this embodiment, the first driving mechanism includes a first air cylinder, the second driving mechanism includes a second air cylinder (both shown in the figure), the first air cylinder and the second air cylinder are fixed to the frame 1, and the first pressure roller 36 and the second pressure roller 37 perform up-and-down lifting through the extension and retraction of the first air cylinder and the second air cylinder.

The pushing mechanism comprises a pushing cylinder 40 and a thimble 41, the cylinder body of the pushing cylinder 40 is fixed with the frame 1, and the thimble 41 is vertically fixed with the piston rod of the pushing cylinder 40. The pushing cylinder 40 pushes the thimble 41 to move downward, and the thimble 41 pushes the pull ring in the material guiding hopper 13 to the clamping passage of the clamping plate.

The grip block includes left splint 5a and right splint 5b, forms the centre gripping passageway between left splint 5a and the right splint 5b, and left splint 5a and the mutual reverse bend in top of right splint 5b make the apical pore of centre gripping passageway be the loudspeaker form, and left splint 5a passes through compression spring 42 and the one side inner wall connection of pull ring seat hole 4, and right splint 5b passes through compression spring two 43 and the opposite side inner wall connection of pull ring seat hole 4. When pressing from both sides the pull mechanism and down pull-down the pull ring, the leather pulling-on piece receives the clamping effect veneer of left splint 5a and right splint 5b, sets up the effect of compression spring 42 and compression spring two 43 and makes left splint 5a and right splint 5b can laminate the leather pulling-on piece, can keep certain yielding again, makes the leather pulling-on piece smoothly pass through from the centre gripping passageway.

As shown in fig. 9, the screen layer 27 is fixed by an elastic collar 44 in contact with the inner wall of the cylinder surface of the inner cylinder 20 along the circumferential direction thereof, the elastic collar 44 has an open ring shape, and the elastic collar 44 has a mesh 44a penetrating the inner and outer ring surfaces.

A pulling-on piece leading-out plate 45 is arranged at the pulling-on piece outlet 24, one end of the pulling-on piece leading-out plate 45 is fixed with the inner wall of the outer roller 21, and the other end of the pulling-on piece leading-out plate is abutted against the outer wall of the inner roller 20, so that the glued leather pulling-on piece is separated from the pulling-on piece outlet 24.

In this embodiment, the actuator concerned is connected to a controller, for example, a cylinder in a driving mechanism for moving the shutter 6 laterally back and forth, a telescopic cylinder, a finger cylinder and a rotary cylinder 12 in a clamping and pulling mechanism, and the pushing cylinder 40 in the pushing mechanism, etc. are connected with a controller through a circuit, the controller can be arranged on the frame 1, in the whole working process, the execution action time of each execution element is debugged through the controller, so that the packaging from gluing to the pull ring of the leather pull sheet is smoothly carried out, in the embodiment, because the frame 1 is of the prior art structure, and the components can be connected with the frame 1 through a bracket and other modes, the structure of the bay 1 is therefore not shown in its entirety, nor is the pattern of connections of some components to the bay 1 shown in its entirety, such as the glue storage barrel 29 in the glue supply circulation mechanism, the pushing cylinder 40 in the pushing mechanism, etc., are all fixed with the frame 1 through a bracket.
