Description

Perforating device for POF heat shrinkable film

Technical Field

The utility model relates to a POF thermal contraction membrane perforating device belongs to POF thermal contraction membrane processing equipment field.

Background

The POF heat shrinkable film is a novel environment-friendly shrink film which is most widely used and rapidly developed in the world at present, has the advantages of high transparency, high shrinkage, high toughness, high heat sealing performance, antistatic property, excellent cold resistance, safety, reliability and the like, and is widely applied to outer packaging and integral packaging of products in various industries such as food, cosmetics, gifts, medicines, stationery, toys, audio and video products, electronics, wood products, plastic hardware, daily necessities and the like.

For the convenience of using the POF heat shrinkable film after preparation, the prepared film needs to be perforated with easy-to-tear lines sometimes, so that the film is more convenient to use.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: provides a POF thermal contraction film perforating device with smooth perforation and lower cost.

POF thermal contraction membrane perforating device, including support body and platen, the top of platen is equipped with first guide roll, backing roll, second guide roll, third guide roll and wind-up roll from a left side to the right side in proper order, first guide roll, backing roll and second guide roll are the V type, are fixed with step motor and cylinder on the support body, step motor hookup wind-up roll, the tailpiece of the piston rod portion of cylinder runs through the platen and is fixed with the connecting plate, the top of connecting plate is fixed with the faller, install one row and the corresponding perforating needle of backing roll on the faller.

Both ends of the bottom of the connecting plate are fixed with guide shafts, the two guide shafts are matched with guide sleeves, the two guide sleeves are embedded at the top of the bedplate, the guide effect is achieved, and the working stability is better.

The stepping motor is connected with the winding roller through a transmission belt.

The supporting roller is a rubber roller.

Compared with the prior art, the utility model beneficial effect who has is:

Drawings

Fig. 1 is a front view of the present invention;

fig. 2 is a cross-sectional view at a-a in fig. 1.

In the figure: 1. a frame body; 2. a stepping motor; 3. a transmission belt; 4. a platen; 5. a wind-up roll; 6. a third guide roller; 7. a second guide roller; 8. a support roller; 9. a first guide roller; 10. a POF heat shrinkable film; 11. a cylinder; 12. a guide sleeve; 13. a guide shaft; 14. a perforating needle; 15. a needle plate; 16. a connecting plate.

Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings:

as shown in fig. 1 and 2, POF thermal contraction membrane perforating device, including support body 1 and platen 4, the top of platen 4 is equipped with first guide roll 9, backing roll 8, second guide roll 7, third guide roll 6 and wind-up roll 5 from a left side to the right side in proper order, first guide roll 9, backing roll 8 and second guide roll 7 are the V type, be fixed with step motor 2 and cylinder 11 on the support body 1, step motor 2 hookup wind-up roll 5, platen 4 is run through to the piston rod tip of cylinder 11 and is fixed with connecting plate 16, the top of connecting plate 16 is fixed with faller 15, install one row and the corresponding perforating needle 14 of backing roll 8 on the faller 15.

In a preferred embodiment: guide shafts 13 are fixed at two ends of the bottom of the connecting plate 16, guide sleeves 12 are matched on the two guide shafts 13, and the two guide sleeves 12 are embedded at the top of the bedplate 4 to play a role in guiding and have better working stability; the stepping motor 2 is connected with the winding roller 5 through a transmission belt 3; the support roller 8 is a rubber roller.

When the POF heat shrinkable film perforating machine is used, POF heat shrinkable films sequentially pass through the first guide roller 9, the support roller 8, the second guide roller 7 and the third guide roller 6 and are wound through the winding roller 5 under the action of the stepping motor 2, when the POF heat shrinkable films reach a perforating position, the air cylinder 11 acts, a piston rod of the air cylinder 11 extends out, the perforating needle 14 is driven by the connecting plate 16 and the needle plate 15 to pierce the POF heat shrinkable films on the support roller 8, so that perforating of easy-tear lines of the POF heat shrinkable films is completed, after the perforating is completed, the air cylinder 11 retracts to wait for next perforating, and meanwhile, the stepping motor 2 drives the winding roller 5 to continue to wind.
