Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat shrinkable film rolling, in particular to a PE heat shrinkable film rolling device. Background Art
[0002] PE heat shrink film is a thermoplastic polymer material, mainly made of PE polyethylene.
[0003] When the PE heat shrink film is made into a continuous tubular film through an extruder, it is then blown to expand the continuous tubular film to form a biaxially stretched film. Next, it will pass through a traction forming cooling device to cool the film and maintain a stable width and thickness. Later, the heat shrink film will be rolled up by a film rolling device for later storage in the warehouse.
[0004] When a film roll on a film roll device has rolled up a certain amount of film body and can no longer roll up the film, it is necessary to cut the film body first, then remove the film roll with a certain amount of film body, and then install a new film roll so that it can be rolled up onto the new film roll later.
[0005] At present, when the existing membrane winding device is used to cut the membrane body, due to the high toughness and softness of the membrane body itself, when an ordinary cutting knife is used to cut it, the membrane body at the cutting position is easy to adhere to the surface of the ordinary cutting knife, affecting the cutting operation, and further affecting the normal film winding working stroke of the membrane body.
[0006] In addition, since the membrane body itself is in a stretched and flattened state and has a certain tensile force, after being cut, the cut part of the membrane body will shrink rapidly toward the traction molding and cooling device. The operator also needs to stretch and flatten the shrunken and deformed membrane body again, which is very troublesome. Utility Model Content

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] An upper clamping plate 52 is provided on the upper slide 51, a lower slide 61 is slidably connected in the lower slide groove 6, a lower clamping plate 62 is provided on the lower slide 61, a bearing seat 31 is provided on the bracket 3, and a bearing 32 is provided in the bearing seat 31;
[0030] A double-thread screw 7 is provided in the bearing 32, and a rotating handle 71 is provided on the double-thread screw 7. Damping plates 8 are provided on the upper clamping plate 52 and the lower clamping plate 62. The cutting cylinder 4 and the slide seat 41 are a group, and the whole is a commonly used rodless cylinder.
[0031] The traction forming cooling device 21 is a device commonly used in the film body film rolling device process. In addition, the film body 22 is a PE heat shrinkable film, which are all existing technologies.
[0032] The laser head 43 is arranged at the lower end of the laser generator 42. There is a distance between the lower end surface of the laser head 43 and the upper end surface of the membrane body 22. The laser generator 42 and the laser head 43 are a group, which is the existing technology.
[0033] The bracket 3 is a U-shaped structure and is through-through from left to right. The inner longitudinal width of the bracket 3 is not less than the longitudinal width of the membrane body 22 to avoid collision and friction between the bracket 3 and the membrane body 22.
[0034] The double-wire screw 7 is threadedly connected to the upper slide 51 and the lower slide 61 respectively, and the turning handle 71 is arranged at the top of the double-wire screw 7. The double-wire screw 7 is a forward and reverse rotating threaded rod. When the double-wire screw 7 rotates forward and reverse, the upper slide 51 and the lower slide 61 can be moved closer or farther away at the same time, and the upper splint 52 and the lower splint 62 can be moved closer or farther away at the same time, which is very convenient.
[0035] The bearing 32 is embedded in the bearing seat 31 , and the mounting hole of the bearing 32 is fixedly sleeved with the double-thread screw 7 to prevent the double-thread screw 7 from sliding up and down.
[0036] The sliding connection part between the upper slide 51 and the upper slide 5 is a trapezoidal structure when viewed from above, and the sliding connection part between the lower slide 61 and the lower slide 6 is a trapezoidal structure when viewed from above, so as to prevent the upper slide 51 and the lower slide 61 from slipping.
[0037] The damping plates 8 are respectively arranged at one end of the upper clamping plate 52 and the lower clamping plate 62 facing the membrane body 22. The damping plates 8 are made of NBR nitrile rubber, have excellent damping and anti-slip properties, and will not cause pinching to the membrane body 22.
[0038] Working method: The film body 22 is stretched and flattened horizontally to the right from the right discharge port of the traction forming and cooling device 21, and then a part of the right end of the film body 22 is rolled onto the right film rolling roller 12 to achieve the overall stretching and flattening positioning effect of the film body 22. Then, the film rolling motor 11 is started to drive the film rolling roller 12 to rotate clockwise at a uniform speed, and the film body 22 can be rolled from left to right at a uniform speed (this is the existing technology);
[0039] When a certain amount of the film body 22 is rolled up, the film can no longer be rolled up, the film rolling motor 11 is stopped, and then the cutting cylinder 4 and the laser generator 42 are started. The cutting cylinder 4 will drive the slide 41, the laser generator 42, and the laser head 43 to slide longitudinally at a uniform speed and then reset. In the process of longitudinal sliding, the started laser generator 42 will emit a laser beam vertically downward at the laser head 43. The laser beam emitted vertically downward will move longitudinally and perform accurate and rapid laser cutting of the film body 22 below. It is necessary to cut the film body first to avoid the film body 22 sticking to the surface of the ordinary cutting knife during the cutting operation of the film body 22, thereby avoiding affecting the cutting operation, thereby ensuring the normal film rolling working stroke of the film body 22;
[0040] Then the film roll 12 on which a certain amount of film body 22 is currently rolled is removed, and a new film roll 12 is installed so as to be rolled onto the new film roll 12 later (this is the prior art).
[0041] In addition, before cutting the membrane body 22, the handle 71 can be rotated clockwise to drive the double-thread screw 7 to rotate clockwise, and the upper slide plate 51 can be driven to slide downward along the upper slide groove 5 through the thread transmission, and the lower slide plate 61 can be driven to slide upward along the lower slide groove 6 at the same time. After the upper clamping plate 52 and the lower clamping plate 62 both clamp the membrane body 22 stably by the damping plate 8, the rotation of the handle 71 can be stopped and the cutting operation can be performed. After cutting, since the left side of the membrane body 22 is clamped, the cut part of the left side of the membrane body 22 is prevented from shrinking rapidly toward the traction molding cooling device 21, thereby avoiding the operator having to perform the troublesome operation of stretching and flattening the shrunken and deformed membrane body 22 again.
[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
