The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 5, the utility model is used for the cloth-pressing device of granny rag machine, comprises left plate 1, right plate 16, by bolt work feed belt wheel 12 is installed on left and right side plate.In work feed belt wheel 12 installed inside work feed cylinder 5 is arranged.The cutting cloth slides into above the cloth guide plate for 5 times by the work feed cylinder.To reach the previous work requirement of compress.The cloth guide plate 10 that is obliquely installed is installed below work feed cylinder 5, and cloth guide plate 10 comes support fixation by cloth guiding stay pipe 11 and the cloth guide plate carriage 9 that is located between the left and right side plate.Cloth guide plate 10 is installed on cloth guiding stay pipe 11 and the cloth guide carriage 9 by screw.Cloth guide carriage 9 is installed on the left and right side plate by screw.
Guide supporting pipe 7 fixedly is located between described left plate 1, the right plate 16, and guide supporting pipe 7 and cloth guiding stay pipe 11 can keep the constant distance of and arranged on left and right sides plate.Center fixed seat 6 is fixedly mounted on the inboard of guide supporting pipe 7, center fixed seat 6 offers the endoporus of perforation, the compressing tablet fixed axis is located in the endoporus, and the compressing tablet fixed axis comprises compressing tablet left side fixed axis 22, compressing tablet center fixed axle 4 and the compressing tablet right side fixed axis 18 that is linked in sequence.Center fixed seat 6 can split from the centre, and purpose is the convenient compressing tablet center fixed axle 4 of installing.The same side of compressing tablet left side fixed axis 22, compressing tablet center fixed axle 4 and compressing tablet right side fixed axis 18 is planished, and forms surface planing, and compress sheet 8 is fastenedly connected on this surface planing by screw, and compress sheet 8 extends to the upper surface of cloth guide plate 10.Shown in Fig. 6 A, Fig. 6 B, be concavo-convex embedded connection between compressing tablet left side fixed axis 22, compressing tablet center fixed axle 4 and the compressing tablet right side fixed axis 18.In when work, compressing tablet left side fixed axis 22, compressing tablet center fixed axle 4 and compressing tablet right side fixed axis 18 rotate simultaneously along center line, and remain on the same axis.
As shown in Figure 3, Figure 4, drive unit is located at the outside of left plate 1 and right plate 16, comprise electric clutch 2, connecting plate 17 (as Fig. 7), pressing plate 15 and microswitch 13, the output shaft 3 of electric clutch 2 connects with connecting plate 17, the end of compressing tablet fixed axis is socketed in the middle position of connecting plate 17, one end of connecting plate 17 connects with pressing plate 15, and pressing plate 15 is provided with near the position of microswitch 13.
On left and right side plate, be separately installed with electric clutch seat 19 by fixed axis 20, back-up ring 21.Electric clutch 2 is installed on electric clutch seat 19.In use, put behind cloth guide plate 10 when cutting cloth shop, the primary control program of granny rag machine can send a signal to controller PLC, and controller PLC can provide a 24V power supply to electric clutch 2 by control relay.Electric clutch 2 starts under the effect of 24V power supply, and the output shaft 3 of electric clutch 2 is made stretching motion, promotes connecting plate 17 and rotatablely moves.
Connecting plate 17 and pressing plate 15 be contained in compressing tablet left side fixed axis 22, compressing tablet center fixed axle 4 by locking Guan County, above the compressing tablet right side fixed axis 18.Connecting plate 17 and pressing plate 15 opposite direction settings are 180 degree and install.
When connecting plate 17 rotatablely moves, can make compressing tablet left side fixed axis 22, compressing tablet center fixed axle 4, compressing tablet right side fixed axis 18 rotatablely move in the same way, be installed in compressing tablet left side fixed axis 22, compressing tablet center fixed axle 4, the compress sheets above the compressing tablet right side fixed axis 18 simultaneously and rotatablely move in the same way, promptly and the cutting cloth that put on cloth guide plate 10 8 pairs of shops of compress sheet carries out the compress process.
As shown in Figure 4, simultaneously, after 8 pairs of cutting clothes of compress sheet carry out the compress process, because connecting plate 17 is the opposite direction setting with pressing plate 15, when pressing plate 15 touches microswitch 13, microswitch 13 can transmit the primary control program that a signal is given the granny rag machine, and the order cut-off knife cuts the cutting cloth.After cut-off knife was finished cutting operation to the cutting cloth, the primary control program of granny rag machine can be cut off the electricity supply, and made electric clutch 2 be in the state of quitting work.Because of electric clutch 2 resets to the home position, make pressing plate 15, compressing tablet left side fixed axis 22, compressing tablet center fixed axle 4, compressing tablet right side fixed axis 18 return to reset condition by connecting plate 17 drives, compress sheet 8 also resets simultaneously.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
