Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

A kind of dedusting mechanism of PVC film production line rotates between two racks 1 as shown in Figure 1, including two racks 1 Connection is the prior art there are five chill roll 2,2 structure of chill roll, and details are not described herein.After film by two chill rolls 2 Outside is fixed with cloth set 3 (as shown in Figure 5), and cloth set 3 is made and cylindrical of non-woven fabrics, therefore PVC film first passes through three After a chill roll 2 is quickly cooled down sizing, the chill roll 2 of cloth set 3 is cased with using two, so that surface dust is removed, then It is wound, is conducive to improve product quality.

As shown in Figure 1, two chill rolls 2 for being cased with cloth set 3 are provided with clearer 4 respectively at upper and lower two sides, clearer 4 is The rubber layer of one layer of adhesive dust is covered on the outside of dedusting rubber roller, i.e. metallic roll.Clearer 4 and cloth set 3 are close to, therefore PVC is thin Film from cloth set 3 away from the side of clearer 4 around out-of-date, clearer 4 can remove the dust being attached in cloth set 3, and then make cloth set 3 Good dust removing effects can be kept for a long time；When PVC film passes through between cloth set 3 and clearer 4, be conducive to improve removal Effect.

As shown in Figure 2 and Figure 3,4 both ends of clearer are provided with attachment base 5, and attachment base 5 is connected towards the side of clearer 4 There is connector 9, connector 9 includes the support semi-ring 91 for being fixedly connected with attachment base 5 and being close to 4 end of clearer downside, branch Support 91 one end of semi-ring is hinged with locking semi-ring 92.Support semi-ring 91 and locking semi-ring 92 can rotate towards each other until encasing clearer 4 Axle portion, support semi-ring 91 and locking semi-ring 92 are fixedly connected to latch 93, two latch 93 away from one end of hinged place Between connected by clamping screw 94 and locking nut 95.After backing out clamping screw 94 and locking nut 95, locking semi-ring 92 is just It can separate, just can be separated with support semi-ring 91 after being lifted on clearer 4 and remove with support semi-ring 91, and then convenient for cleaning or more It changes.

As shown in Fig. 2, 1 upside of rack or downside are fixedly connected with the connection frame 6 being caught in for attachment base 5.Connection frame 6 is in door Font, attachment base 5 are only capable of moving up and down in connection frame 6.The tune being threadedly coupled with attachment base 5 is vertically provided in connection frame 6 Screw rod 7 is saved, 7 one end of adjusting screw rod and the rotation connection of connection frame 6, the other end and rack 1 are rotatablely connected.Therefore adjusting screw rod 7 is twisted Seat 5 just can be drivingly connected after turning to move up and down, so that clearer 4 is mobile towards or away from cloth set 3.5 two sides of attachment base are equal It is fixedly connected with guide pad 51, the guide groove 61 for being caught in and moving up and down for guide pad 51 is provided on the inside of connection frame 6.Attachment base The compactness connected between 5 and connection frame 6 improves.

As shown in Fig. 2, Fig. 5,1 inner cavity of rack is adjusting cavity 11, and adjusting cavity is protruded into one end of adjusting screw rod 7 towards rack 1 11 and it is connected with actuator 8, actuator 8 includes the driven gear 81 being fixedly and coaxially connected with adjusting screw rod 7, and driven gear 81 is nibbled Conjunction has driving gear 82, and driving gear 82 and driven gear 81 are bevel gear.Driving gear 82 has been fixedly and coaxially connected level The drive shaft 83 of setting, drive shaft 83 and rack 1 are rotatablely connected.Therefore after rotate driving axis 83, driving gear 82 can just be driven Rotation, driving gear 82 drive driven gear 81 to rotate, so that adjusting screw rod 7 rotates, clearer 4 is just moved up and down.It drives Moving axis 83 stretches out rack 1 and is fixedly connected with driving handle 84, twists convenient for staff.1 upside of rack or downside screw thread connect It is connected to the locking bolt 85 for holding out against drive shaft 83.After tightening locking bolt 85, drive shaft 83 just not can rotate, so that cleaning The position of roller 4 is relatively fixed.

The course of work:

PVC film first bypasses three chill rolls 2, further around two cloth sets 3 are crossed, and completes cooling and shaping and dedusting.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model Within the scope of.
