Embodiment Construction

[0023] The present invention will be described in further detail below by means of specific embodiments:

[0024] The reference signs in the accompanying drawings of the specification include: frame 1, pressure roller 2, guide groove 21, second elastic member 22, pressure roller shaft 23, winding shaft 3, retractable block 31, block groove 32, film roll 4. Groove 41 , toothed part 51 , non-toothed part 52 , driving gear 6 , transmission mechanism 7 , first rack 8 , limit ring 81 , first elastic member 82 , and push block 83 .

[0025] The embodiment is basically as figure 1 , figure 2 , image 3 Shown:

[0026] 1) Set the film roll 4 on the winding shaft 3. When the set is set, the retractable flap 31 on the winding shaft 3 is pressed into the flap groove 32 provided on the winding shaft 3 by the film roll 4. When the concave on the film roll 4 When the groove 41 moves to the block slot 32, the retractable block 31 pops out of the block slot 32 and snaps into the groove 4...

Abstract

The invention discloses a heat shrinkage film winding method. The method comprises the following steps that (1) a film reel is arranged on a winding shaft in a sleeving mode to be positioned; (2) a machine is started, the film reel rotates along with the winding shaft, a heat shrinkage film passes through the space between a press roll and the film reel and is pressed and wound onto the film reel; the press roll is jacked up by the film reel continuously; meanwhile, the press roll pushes a second rack located at the upper end of the press roll to vertically move upwards; a first elastic element arranged between a limiting buckle and the end of a first rack arranged close to the side of the winding shaft is compressed along with horizontal movement of the first rack; (3) when the heat shrinkage film is wound onto the film reel, the first rack is driven by the first elastic element to be rapidly popped towards the film reel and provide push force to the film reel; under the action of the push force, the film reel slides out of the winding shaft, and reel discharging is completed; and (4) after completion of reel discharging, the press roll loses upward supporting force and moves vertically downwards, and a device restores. By means of the scheme, the problem that reel discharging cannot be completed automatically in the prior art can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic film processing, and in particular relates to a method for winding heat-shrinkable films. Background technique [0002] In the film production line, the auxiliary equipment that winds the produced film on the paper core to form a roll is called a winder or a coiler. [0003] During the winding process of the film, the cooperation of the pressure roller and the winding roller is usually required to timely discharge the air in the film roll and flatten the film surface so as to achieve the purpose of dense film roll and smooth film surface. At present, the commonly used winding devices for heat shrinkable films are generally used in conjunction with a pressure roller and a winding roller up and down. By applying a certain pressure on the pressure roller, the pressure roller is closely attached to the winding roller to achieve The purpose of exhaust flattening. Considering the effect of frict...
