Abstract
The utility model relates to lapping machine technical field, in particular to a film drawer for a lapping machine. The utility model comprises a chassis which is provided with a film fixing bar and a transmission rod fixing skeleton; a transmission rod is arranged between the transmission rod fixing skeleton and the chassis; a rotary stand, on which an auxiliary transmission rod is arranged, is installed on the transmission rod fixing skeleton; a top pressure block is arranged between the side face of the auxiliary transmission rod and the rotary stand; one end of a rotary screw threads through the rotary stand to prop up the top pressure block. The auxiliary transmission rod of the utility model is arranged on the rotary stand, so spinning of the film is convenient. Furthermore, the rotary screw props up the top pressure block, so friction to the transmission rod can be increased by exerting pressure to the top pressure block by the rotary screw, realizing the effect of pressing the film tight so as to draw the film. The utility model has the advantages of simple structure and good using effects.
Description
Technical field:
The utility model relates to the wrapping machine technical field, particularly wrapping machine film stretching device.
Background technology:
Wrapping machine is used for film is wrapped in predetermined object automatically, play the dustproof and fixing effect that waits in order to will be scheduled to the object parcel, the film stretching device of wrapping machine generally comprises film fixed link, a plurality of drive link, when the film coiled strip is installed, earlier the film coiled strip is placed on the film fixed link, then film is walked around between a plurality of drive links, drawn outside the film stretching device stand-by again.Wherein, this existing film stretching device has bigger defective: one, because drive link plays the effect of accessory drives, distance between each drive link is very little, and the position of drive link is a predetermined fixed, the dismounting inconvenience is so will draw also very inconvenience from walking around between a plurality of drive links with film at every turn; Two, for film can rationally be utilized, the general practice that film is elongated that adopts, but the film coiled strip of buying when producing is unstretched, and the film stretching device of wrapping machine only has the film fixation and can not film be stretched, and can't resolve new technical matters.
The utility model content:
The purpose of this utility model is to provide wrapping machine film stretching device at the deficiencies in the prior art.
For achieving the above object, the utility model adopts following technical scheme:
It comprises underframe, has film fixed link and drive link fixed mount on the underframe, between drive link fixed mount and the underframe drive link is installed; On the drive link fixed mount swivel mount is installed, the accessory drives bar is installed on the swivel mount; Be folded with the roof pressure piece between the side of accessory drives bar and the swivel mount, an end of rotary screw passes swivel mount conflict roof pressure piece.
One side of described roof pressure piece is that arc, a side relative with this arcwall face offer containing hole, and spring is installed in the containing hole, and an end and spring that rotary screw passes swivel mount offset.
Described roof pressure piece is positioned at the first half of accessory drives bar.
The beneficial effects of the utility model are: accessory drives bar of the present utility model is installed on the rotating swivel mount, so rotating easily of film, in addition, because rotary screw conflict roof pressure piece so can exert pressure to the roof pressure piece by rotating rotary screw, is given the accessory drives bar with this transmission of pressure again, and then increase is to the friction force of drive link, thereby realize pressing the effect of film, make film obtain stretching, have advantages such as simple in structure, that result of use is preferable.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of roof pressure piece of the present utility model
The specific embodiment:
See accompanying drawing 1, the utility model comprises underframe 10, and underframe 10 is directly fixed on the wrapping machine; Have film fixed link 12 and drive link fixed mount 14 on the underframe 10, the film coiled strip promptly is placed on the film fixed link 12, between the upper surface of drive link fixed mount 14 and the underframe 10 drive link 16 is installed vertically; Swivel mount 20 is installed on the drive link fixed mount 14, swivel mount 20 can rotate in drive link fixed mount 14, accessory drives bar 22 vertically is installed on the swivel mount 20, with swivel mount 20 when the inner rotary, can make accessory drives bar 22 away from drive link 16, promptly can draw the stretching device outside with film very easily this moment from passing between accessory drives bar 22 and the drive link 16, when swivel mount 20 is inwardly rotated, can reduce the distance between accessory drives bar 22 and the drive link 16, be butted on drive link 16 until accessory drives bar 22, this moment, accessory drives bar 22 compressed film with drive link 16; Be folded with roof pressure piece 30 between the side of accessory drives bar 22 and the swivel mount 20, one end of rotary screw 40 passes swivel mount 20 conflict roof pressure pieces 30, because rotary screw 40 conflict roof pressure pieces 30, so can exert pressure to roof pressure piece 30 by rotating rotary screw 40, give accessory drives bar 22 with this transmission of pressure again; Rotating speed by control drive link 16, accessory drives bar 22 is twined the effect of film and external pull, driven rotary frame 20 steerage gear bars 16, drive link 16 compresses film and rotation simultaneously jointly with accessory drives bar 22, and the film externally effect of pulling force and drive link 16 and the pressure of accessory drives bar 22 produces down and stretches.
See accompanying drawing 2, better match with accessory drives bar 22 for making roof pressure piece 30 that a side of described roof pressure piece 30 is an arc, this arc one side matches with accessory drives bar 22; A side relative with this arcwall face of roof pressure piece 30 offers containing hole 32, and spring 34 is installed in the containing hole 32, and an end and spring 34 that rotary screw 40 passes swivel mount 20 offset; Rotary screw 40 compresses spring 34 when rotating, deformation generation elastic force by spring 34 acts on the roof pressure piece 30, and to sinciput, roof pressure piece 30 stressed backs are to sinciput accessory drives bar 22 with roof pressure piece 30, make accessory drives bar 22 press film, thereby make film obtain stretching.
Described roof pressure piece 30 is positioned at the first half of accessory drives bar 22, so just can be both an end of accessory drives bar 22 be applied application force, makes film obtain stretching, and has simplified the structure of device.
The utility model not only can make the film roll material easy for installation but also can make film obtain stretching, Have the advantages such as simple in structure, that result of use is better.
