Description

Technical Field

[0001] The utility model relates to the technical field of PE film recovery equipment, in particular to a side material recovery machine for PE film production. Background Art

[0002] PE protective film is a macromolecular organic compound with the simplest structure and the most widely used macromolecular material in the world today. PE protective film uses special polyethylene plastic film as the base material and is divided into high-density polyethylene protective film, medium-density polyethylene protective film and low-density polyethylene protective film according to different densities. The biggest advantage of PE film is that the protected product is not polluted, corroded or scratched during production, processing, transportation, storage and use, and the original smooth and shiny surface is protected.

[0003] In the production process of PE film, in order to ensure the beauty of the finished film roll, the excess edge material is often cut off, and the edge material falls beside the cutting machine. Since PE film has a certain elasticity, these edge materials are very easy to bend and curl after cutting. Over time, these edge materials accumulate. The fluffy edge materials not only occupy the space around the production equipment and make the work area messy, but also need to be compressed before packaging when recycled, which brings trouble to the recycling of PE film residues.

[0024] The outer wall of the reel 6 is sleeved with a disposable paper tube 7, and a triangular prism 8 is fixedly connected to the outer wall of the reel 6. Three triangular prisms 8 are provided, and the three triangular prisms 8 are evenly distributed on the outside of the reel 6 in a ring shape. The triangular prisms 8 fit tightly with the inner wall of the disposable paper tube 7, and the triangular prisms 8 squeeze the inner wall of the disposable paper tube 7, so that the disposable paper tube 7 is sleeved and fixed on the outside of the reel 6.

[0025] In this embodiment, two through holes 9 are provided on the outer walls at both ends of the disposable paper tube 7. The two through holes 9 are connected to each other. One end of the PE film production scraps is passed through the through hole 9 and fixed, and then the PE film scraps are rolled up as the disposable paper tube 7 is rolled up.

[0026] A limiting mechanism 17 is arranged inside the right bracket 3, and the limiting mechanism 17 includes a mounting groove 11 opened on the inner side of the right bracket 3, arc grooves 12 are opened on both sides of the inner wall of the mounting groove 11, and the inner wall of the arc groove 12 is slidably connected to a limiting block 13, and a spring 14 is fixedly connected between the limiting block 13 and the inner wall of the arc groove 12, and a connecting rope 15 is fixedly connected to the bottom of the limiting block 13, and the connecting rope 15 passes through the side wall of the right bracket 3 and is fixedly connected to a pull rod 16, and the support seat 10 is located inside the mounting groove 11, and the winding shaft 6 can be limited by the limiting mechanism 17, and when unlocking, it is only necessary to pull the pull rod 16 to drive the connecting rope 15 to pull the two limiting blocks 13 to contract, so as to release the limit on the support seat 10.

[0027] Among them, the driving shaft of the servo motor 4 passes through the left bracket 2 and is fixedly connected to the shaft seat 5. The winding shaft 6 is rotatably connected to the inside of the shaft seat 5 through a rotating shaft. When one end of the winding shaft 6 loses the limit of the limiting mechanism 17, it can rotate around the rotating shaft inside the shaft seat 5, lift the winding shaft 6, and replace the disposable paper roll 7.

[0028] A base 18 is fixedly connected to one side of the outer wall of the base 1, a linear motor 19 is fixedly connected to the top of the base 18, a slide 20 is fixedly connected to the driving end of the linear motor 19, both ends of the top of the slide 20 are fixedly connected to vertical frames 21, and a shaping roller 22 is connected to the bearing between the two vertical frames 21.

[0029] Among them, the two upright frames 21 are fixedly connected to the sides close to each other with arc blocks 23, and the arc blocks 23 are located between the two shaping rollers 22. Through the limiting of the smooth arc blocks 23 on both sides and the rubbing of the two shaping rollers 22, it is convenient to limit the shape of the scraps so that they can be shaped into thin strips as much as possible. When the position is adjusted by sliding with the linear motor 19, it is convenient to make the PE film scraps be evenly reciprocated and connected to the outside of the disposable paper tube 7.

[0030] Before use, first connect the servo motor 4 and the linear motor 19 to an external power supply, pass one end of the cut PE film scrap through two shaping rollers 22, and then pass through the through holes 9 at either end to be tied and fixed.

[0031] When in use, start the servo motor 4 to drive the winding shaft 6 to rotate, and drive the PE film scraps to be rolled around the disposable paper tube 7, so as to facilitate the recycling of the scraps. At the same time, start the linear motor 19 to drive the slide 20 to reciprocate on its top, so that the PE film cut scraps are reciprocated and evenly wound around the outside of the disposable paper tube 7. This not only increases the total amount of scraps that can be wound on the unit disposable paper tube 7, but also makes the rolling and recycling uniform. After taking it down, it is easy to recycle and pack, which brings convenience to the staff.

[0032] When the disposable paper roll 7 is rolled into place, the pull rod 16 is pulled to drive the two limit blocks 13 to be retracted into the arc groove 12.

The support base 10 and the winding shaft 6 are fixed by the spline shaft at the end surface, and can be directly pulled out for disassembly. Then the disposable paper tube 7 is removed from the outside, and the PE film scraps are packaged and recycled. At the same time, a new disposable paper tube 7 is replaced and sleeved on the outside. Repeat the above preparations to continue the scrap recycling work.
