When adopting technique scheme, further technical scheme below the utility model also can adopt or make up and adopt:
Described device be provided with send-back flower wheel bonded assembly first swinging gear, with fastening belt flower wheel bonded assembly second swinging gear; Described device also is provided with the main shaft of drive cam rotation and the drive motor of main shaft, is connected with first cam that acts on first swinging gear on the described main shaft.
Described send-back driving wheel is in the below of sending the band track, and the fastening belt driving wheel is in the top of sending the band track.
Described send-back driving wheel is in the below of sending the band track, and the fastening belt driving wheel is in the top of sending the band track.
The beneficial effects of the utility model are: the sending band, move back band of compress, the fastening belt apparatus structure is simple, send-back and fastening belt good working effect.Owing to adopt the technical solution of the utility model, provide send-back operation power and fastening belt operation power by a motor, and send-back work is integrated in the same wheels finishes, when guaranteeing that send-back and fastening belt work have good result, make compress in-to-in structure simpler.
The specific embodiment
With reference to accompanying drawing.The utility model comprises send-back flower wheel 12, the fastening belt driving wheel 21 of send-back driving wheel 11 and cooperation with it and the fastening belt flower wheel 22 that cooperates with it, described device is provided with main motor 3, and described main motor provides operation power to described send-back driving wheel, fastening belt driving wheel.
The utility model also is provided with tape handler 4 or chain drive, described main motor provides operation power by described tape handler or chain drive to described send-back driving wheel, and described tape handler or chain drive are speedup tape handler or chain drive.Also be tape handler 4 or chain drive and rotating speed send-back driving wheel bonded assembly flower wheel 41 greater than tape handler 4 or chain drive driving wheel 42.
Described main motor 3 provides operation power by train of reduction gears to the fastening belt driving wheel.
The utility model be provided with send-back flower wheel 12 bonded assemblys first swinging gear, with fastening belt flower wheel 22 bonded assemblys second swinging gear; Described device also is provided with the main shaft 5 of drive cam rotation and the drive motor 10 of main shaft 5, is connected with first cam that acts on first swinging gear on the described main shaft 5.
Described first swinging gear comprises swing arm 61, slave arm 62, slave arm 62 is provided with by the bearing 63 of first camming action, and slave arm 62 drives swing arm 61 swings, and the axle mounting of send-back flower wheel is on eccentric stiffener, eccentric stiffener is connected in the swing arm 61, and first swinging gear also is provided with reset tension spring.
Second swinging gear comprises suction tube 71 and fork 72, and described second swinging gear is by suction tube 71 pulling forks 72, and the axle mounting of fastening belt flower wheel is on eccentric stiffener, and eccentric stiffener is connected on the fork 72, between suction tube 71 and the fork 72 extension spring 73 is set.
As shown in Figure 3, Fig. 3 has demonstrated the structure of above-mentioned eccentric stiffener, above-mentioned eccentric stiffener comprises connecting panel 201 and is installed in the eccentric shaft 202 of connecting panel one side that eccentric shaft 202 links to each other with swinging gear, the opposite side connection fastening belt flower wheel of connecting panel or the axle 200 of send-back flower wheel.
Described send-back driving wheel is in the below of sending the band track, and the fastening belt driving wheel is in the top of sending the band track.
During work, when the send-back motor is just changeing, strap enters from forward (FWD) mouth 8, gap between process fastening belt flower wheel and fastening belt driving wheel is in tape track, send in the band process send-back driving wheel and send-back flower wheel to draw close the clamping strap, this draws close process by being installed on first camming action on the main shaft 5 in bearing 63, makes the swing of first swinging gear and realizes.
When moving back after band finishes, cam rotation is got back to original position, makes send-back driving wheel and send-back flower wheel separately, move back after band finishes, by inductive switching to, suction tube 71 adhesives make fastening belt driving wheel and fastening belt flower wheel clamp strap, begin to strain strap work.
