Embodiment

It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further Description, but the utility model is not limited to these embodiments.

As shown in figure 1, this removal of impurities splicing machine includes base 1, lower guideway 21, upper rail 22, crossbeam 23, the and of blowing roller 24 Rewinding roller 25, lower guideway 21 and crossbeam 23 are fixedly linked with base 1, and two are provided between upper rail 22 and lower guideway 21 and is indulged Beam 26, guide groove 1 is offered on crossbeam 23, two longerons 26 can slide along guide groove 1, blowing roller 24 and rewinding roller 25 are arranged on crossbeam 23, and a support roller 32 is respectively arranged with two longerons 26, motor is provided with base 1 33, being provided between motor 33 and rewinding roller 25 can drive rewinding roller 25 to rotate and turn when rewinding roller 25 The transmission device that rewinding roller 25 passively stops when dynamic resistance is larger；Cutting for sponge can be cut off by being provided between two longerons 26 Disconnected device；The clamping device for when sponge is cut, preventing sponge from continuing transmission is provided between upper rail 22 and crossbeam 23； Sponge to be detected is furled on blowing roller 24, rewinding roller 25 is furled again, by transmission device, makes sponge Transmission becomes flexible, and when finding some position existing defects of sponge, shearing device cuts off the tool of sponge for defective one section, with This coordinates the soft transmission of transmission device simultaneously, and sponge is had defective both ends clamping and clamped, cut and spelled by clamping device Connect.

As depicted in figs. 1 and 2, transmission device includes the rotating shaft 34 being fixedly linked with rewinding roller 25, and rotating shaft 34 is hollow Structure, is inserted with interior axle 35 in rotating shaft 34, with the oval inner chamber in cross section in rotating shaft 34, is fixedly installed in interior axle 35 The oval valve element 36 in cross section, the major axis of valve element 36 and the short axle equidimension of inner chamber, interior intracavitary are filled with lubricating oil, driving The output shaft of motor 33 is connected with interior axle 35；On the one hand lubricating oil enables to be lubricated between rotating shaft 34 and interior axle 35, Lubricating oil can also be formed the change of volume in interior intracavitary, and lubricating oil is flowed in interior intracavitary under the rotation of valve element 36, from In the presence of mental and physical efforts and stirring inertial flow, rotating shaft 34 is transmitted, and when rotating shaft 34 runs into larger resistance, rotating shaft 34 can It is not damaged, and is only stopped.

It is connected between the output shaft of motor 33 and interior axle 35 by belt.

Shown as shown in Figure 1, Figure 3 and Figure 4, shearing device includes the guide groove 2 41 being opened on longeron 26, is set on longeron 26 Have to be rotatably connected in guide groove 2 41 and push roller 42, be provided with cylinder 1 on upper rail 22, two push roller 42 it Between be connected with a connecting rod 44, offer guide groove 3 45 on connecting rod 44, pushing roller 42 can move along guide groove 3 45, upper rail 22 On be provided with cylinder 1, push rod and the connecting rod 44 of cylinder 1 are fixedly linked, and two cutting blades 46 are provided with connecting rod 44.

It was found that when sponge is locally defective, cylinder 1 drives connecting rod 44 to move down, two on connecting rod 44 cutting blade 46 Cut-out has the both ends of defective sponge.

It is in one 15 ° of angles between guide groove 2 41 and longeron 26；The presence of the angle, can be when cutting off sponge, lower press rolls Cylinder 42 can support being pressed on for sponge larger area on roller 32, and the end after preventing sponge cut-off departs from.

It is in one 15 ° of angles between cutting blade 46 and longeron 26；The presence of the angle can increase the area of sponge otch, Make splicing more firm, can also optimize the aesthetics of splicing mouth.

There are some catch 47 on crossbeam 23, some grades of bars 48, catch 47 are fixedly installed in the side wall of blowing roller 24 It is flexible；Blowing roller 24 is under the stop of shelves bar 48 and catch 47, in the absence of the effect two due to inertia force by blowing Situation, and the tensile force of retracting can be increased, make sponge retracting neat.

As shown in Figure 1 and Figure 4, it is provided with glue spreading apparatus on cutting blade 46；Glue spreading apparatus includes a glue box 51, cutter The discharge opening 52 communicated with glue box 51 is offered on piece 46, the insertion external world is offered on the outside of the lower end of cutting blade 46 with going out Expect the recess 53 in hole 52, be rotatably connected to a roller 54 in recess 53, be provided with limited step 55 on roller 54, in discharge opening 52 Reed 56 is provided with, the outer end of reed 56 is ridden against on limited step 55, and reed 56 can limit the single direction rotation of roller 54.

After sponge is cut the cut-out of blade 46, pulls back, the passive rotation of roller 54, the glue in discharge opening 52 is applied It can splice fixation under the adhesive attraction of glue when being put on sponge otch, then two sponge ports being docked.

Two can be promoted positioned at the cylinder 2 57 in the outside of two longerons 26, cylinder 2 57 respectively by being provided with base 1 Longeron 26 moves towards.

As shown in figure 1, clamping device includes two positioning rolls 61 being rotatably connected on base 1, two positioning rolls 61 have been respectively articulated with a swing arm 62 respectively close to blowing roller 24 and rewinding roller 25, the both ends of upper rail 22, swing arm 62 One end is be hinged with upper rail 22, and the other end of swing arm 62 is fixedly connected with a hold-down roll 63, and two hold-down rolls 63 distinguish position In the top of two positioning rolls 61, one end of hold-down roll 63 and the longeron 26 close to the hold-down roll 63 are connected in swing arm 62 Between an extension spring 64 is set, extension spring 64 is in extended state；Two longerons 26 move in the presence of cylinder 2 57 toward middle part, make The restoring force of extension spring 64 increases, so that swing arm 62 can be pressed on positioning rolls 61, the both ends of sponge are fixed.

Helical spring is provided with pin joint between swing arm 62 and upper rail 22；Under normal conditions, swing arm 62 is in spiral bullet In the presence of spring, certain altitude is lifted, positioning rolls 61 and hold-down roll 63 depart from.

The principle of this sponge removal of impurities splicing machine is as follows：

Sponge is furled to rewinding roller 25 from blowing roller 24, operator observes sponge and whether there is difference and defect, It was found that during defect, start cylinder 1, move down connecting rod 44, push roller 42 and move down, cutting blade 46 moves down, so as in Jiang Hai In the case of continuous both ends clamping, cutting blade 46 cuts off the position of sponge existing defects, when being moved down due to pushing roller 42, Sponge cutting part is not in horizontality, now, cylinder 2 57 or so, two longerons 26 is gone in the same direction, extension spring 64 is drawn Movable pendulum arm 62 moves down, and hold-down roll 63 can press the sponge on positioning rolls 61, prevents its loosening, cylinder one 43 times Position, cutting blade 46 moves up, glue is applied on the otch of sponge, and longeron 26 continues to go in the same direction, until by the two of sponge Individual otch docking, and be compacted to its splicing and fix, this link can manual-alignment otch, after the completion of, unclamp cylinder 2 57, recover just Often, so repeatedly.

Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
