Description

A kind of rolling-up mechanism of plastic packaging film

Technical field

The utility model relates to packaging film production equipment technologies, more specifically, it relates to a kind of plastic packaging film Rolling-up mechanism.

Background technique

Plastic packaging film is the film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, For packing, and it is used as coating layer.Shared share is increasing on the market for plastics package and plastic packet product, especially It is composite plastic flexible package, has been widely used for the fields such as food, medicine, chemical industry, wherein again with food packaging institute accounting Example is maximum, such as beverage packaging, quick-frozen food packaging, cooking food packaging, fast food packaging etc., these products all give people Life brings great convenience.

And packaging film needs the mode by semi-finished plastic packaging film machinery to be wound into material volume in production, after convenient Continuous production line processing, and traditional winding roller surface is smooth, need packaging film first on wind-up roll around it is upper a few, Cai Nengji It is continuous that it is wound；But by packaging film in advance around up during, the packaging film of some softnesses is easy to produce wrinkle；And one A little packaging films that elasticity is good need to press it, and operating process is cumbersome, brings inconvenience.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of winders of plastic packaging film Structure has and is convenient for packaging film around the advantage being rolled on wind-up roll.

To achieve the above object, the utility model provides following technical solution:

A kind of rolling-up mechanism of plastic packaging film, including rack and wind-up roll, the wind-up roll are divided into two semi-cylindricals The first fixture block and the second fixture block, the end face at first fixture block both ends is provided with the sliding slot in the center of circle, second fixture block Both ends be provided with slide along the chute so that the first fixture block and the second fixture block close to or far from slide bar, be provided on the slide bar The shaft connecting with gantry rotation, when first fixture block merges with the second fixture block, the axis of the shaft and wind-up roll exists On one straight line.

Preferably, the sliding slot is T-slot, and the end of the slide bar is provided with T-block, and the sliding slot is set close to opening It is equipped with the limited block that can be offseted with T-block.

Preferably, the bottom of the sliding slot is provided with the extension spring connecting with T-block.

Preferably, the wind-up roll is located at the first fixture block and the joint of the second fixture block is provided with easy kerve.

Preferably, the plane that first fixture block can be bonded with the second fixture block is provided with salient point, the second fixture block setting There is the groove that can cooperate with salient point.

Preferably, the motor being connect with one of shaft with for driving wind-up roll to rotate is provided in the rack.

Preferably, the slide bar and shaft are detachably connected by keyway.

Compared with prior art, the utility model has the following beneficial effects:

When needing to wind packaging film, the first fixture block is pulled to far from the second fixture block direction by easy kerve, So that slide bar is overcome the elastic force of extension spring, form gap between the first fixture block and the second fixture block, after packaging film is put into, makes first Packaging film is clamped in fixture block reset, is cooperated by salient point and groove, packaging film is lockked, prevents it from skidding off；It is driven by motor Shaft rotation, increased winding efficiency；Slide bar and shaft are detachably connected by keyway, convenient for the packaging film wound is removed, The utility model is solved in coiling packaging film, need manually by its elder generation around it is upper a few the problem of, realize convenient for by packaging film Around the advantage being rolled on wind-up roll.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the present embodiment；

Fig. 2 is the schematic diagram of part A in Fig. 1.

In figure: 1, rack；2, the first fixture block；21, sliding slot；211, limited block；212, extension spring；22, salient point；3, second Fixture block；31, slide bar；311, T-block；32, shaft；33, groove；4, easy kerve；5, motor.

Specific embodiment

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

A kind of rolling-up mechanism of plastic packaging film, referring to Fig.1 with 2 comprising rack 1 and wind-up roll, wind-up roll are divided into two The first fixture block 2 and the second fixture block 3 of a semi-cylindrical, the end face at 2 both ends of the first fixture block are provided with the sliding slot 21 in the center of circle, the The both ends of two fixture blocks 3 are provided with the slide bar 31 of 21 slidings along the chute so that the first fixture block 2 and the second fixture block 3 close to or far from, when When first fixture block 2 merges with the second fixture block 3, the axis of shaft 32 and wind-up roll in a straight line, wind-up roll stability of rotation；Pass through First fixture block 2 clamps packaging film with the second fixture block 3, without first by packaging film around upper several circles, realizing the effect convenient for winding.

It is provided with the shaft 32 being rotatablely connected with rack 1 on slide bar 31, is provided in rack 1 and connects with one of shaft 32 The motor 5 connect, to promote winding efficiency for driving wind-up roll to rotate；Shaft 32 passes through keyway and cunning perpendicular to slide bar 31 Bar 31 is detachably connected, convenient for removing the packaging film wound；Sliding slot 21 is T-slot, and the end of slide bar 31 is provided with T-block 311, sliding slot 21 is provided with the limited block 211 that can be offseted with T-block 311 close to opening, there is the sliding for limiting slide bar 31 Range prevents it to be detached from sliding slot 21；The bottom of sliding slot 21 is provided with the extension spring 212 connecting with T-block 311, passes through stretching The elastic force of spring 212, packaging film clamping is tighter, in addition, wind-up roll can be limited in rotation, the first fixture block 2 and the second fixture block 3 The trend being located remotely from each other；Wind-up roll is located at the first fixture block 2 and the joint of the second fixture block 3 is provided with easy kerve 4, and easy kerve 4 is Gap on first fixture block 2 or the second fixture block 3 is set, and convenient for pulling out the first fixture block 2 to applied force, the first fixture block 2 can be with The plane of second fixture block 3 fitting is provided with salient point 22, and the second fixture block 3 is provided with the groove 33 that can cooperate with salient point 22, by convex Packaging film is locked in point 22 and the cooperation of groove 33, is prevented from skidding off, is increased the stability of winding.
