The purpose of this utility model is to provide a kind of inner structure simple by the type of drive that changes existing installation, and can be implemented in the folder of finishing different folding specification filter core processing on the equipment simultaneously.

In order to achieve the above object, technical solution of the present utility model is: a kind of folder that is used for filter material is folded processing, and by frame be provided with it on and interconnective power drive, fold movement, setting device and thrust counterweight and formed.Wherein, the folding movement that directly joins with power drive comprises the upper slitter extrapolation action cam that is fixed on the same axle, cam and be used to drive the disk with cam ring curved groove that upper and lower cutter is done upper and lower motion is moved in the cutter extrapolation down; This drive by power drive and rotatably support on the support plate that connects firmly with frame; Be used to connect the upper and lower knife rest of upper and lower blade affixed with upper and lower cutter push rod respectively, and when stirring cutter relieving by the rotation of upper and lower cutter extrapolation action cam, also by with the cam ring curved groove of its slide block that links to each other separately on disk in move, described slide block is also being done upper and lower motion simultaneously on the support plate slideway that is provided with between upper and lower cutter extrapolation action cam and the disk.

Described power drive comprises motor, retarder and frequency-shift keying, and drives the axle rotation of folding movement by chain.Said setting device comprises that output regulates platen and be used to regulate the driving cylinder of this platen position height or other connecting rod form a kind of, is hinged with driving cylinder piston rod and driving handle simultaneously by a pipe link that is positioned at the frame top.

Major advantage of the present utility model is:

Because the folding movement of this machine is a cam to be promoted upper and lower cutter and alternately moves up and down, and can regulate the position height of output platen arbitrarily and change its lap by setting device by adjustment to upper and lower blade fix screw, thereby realized under one pair of cutter, folding out the filter core of different size, and this stepless adjustment, simple, convenient, the safety of being adjusted into.Simultaneously, but the folding one-shot forming of the filter material of this machine, folding precision height, great efforts, and can finish and add the folding together filter core processing of two layers of twine, three metafiltration materials.

Because this movement adopts the cam drive mode, so stable action, noise is little, and simple in structure again, and cost is low, has promotion and use value.

Description of drawings of the present utility model is as follows:

Fig. 1 is the utility model folder front view;

Fig. 2 is the utility model folder cored structure figure;

Fig. 3 is the cam action schematic diagram of the folding movement of the utility model.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Referring to Fig. 1.This folder comprises frame and as motor, retarder 9 and the frequency-shift keying (not looking out among the figure) of power drive, the axle 4 that is driven folding movement by chain rotates.As shown in fig. 1, axle 4 rotatably supports are on the support plate 2 that connects firmly with frame.In the outside of support plate 2, has the disk 1 of cam ring curved groove with axle 4 affixed; The inboard of support plate 2, same and axle 4 are affixed and be arranged with upper slitter extrapolation action cam 6 and following cutter extrapolation action cam 14 successively respectively, and by pad 15 it are spaced from each other, in order to avoid interference.Concrete structure is referring to Fig. 2.Upper and lower cutter extrapolation action cam lobe branch, its phase difference is 180 °, their rotation can be stirred upper and lower

cutter push rod

5 and 8 respectively and also be driven and affixed upper and lower knife rest 16, the 17 curved orbiting motions of push rod thus; Simultaneously, be equipped with the slide block 3 of crank-like in the end parts of upper and lower knife rest, this slide block 3 both can move in the slideway on the support plate 2, and the cam ring curved groove that its end is also offered on the disk 1 that is arranged in support plate 2 opposite sides simultaneously moves.When this disk 1 rotated with axle 4, slide block 3 drove upper and

lower knife rest

16 and 17 and does upper and lower motion.At this moment, in the upper and lower cutter extrapolation action cam 6 of 180 ° of phase differences and 14 and have under the combined action of disk 1 of cam ring curved groove, upper and

lower knife rest
