Detailed description of the invention

Attached drawing 1 is the structural schematic diagram of plastic grain charger described in the utility model.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

It is a preferred embodiment of plastic grain charger described in the utility model, the modeling refering to shown in attached drawing 1 Material granule feeder is placed in the front end of plastic grain blender, specifically, be before the extruding machine of plastic grain machine is set, with Extruding machine is used cooperatively and carries out charging processing to extruding machine.The plastic grain charger include a balance control mechanism 1, one A automatic weighing machine structure 2.The balance control mechanism 1 includes the balance plate 11 being able to rotate, the control balance of balance plate 11 Balance the reset assembly 13 of control assembly 12 and the rotation reset of auxiliary balance plate 11.The balance control assembly 12 includes one Motor 121 is mounted on the gear 122 rotated on the main shaft of motor 121 by the drive of motor 121 and is meshed with gear 122 Rack gear connecting rod 123.The balance plate 11 is horizontally disposed, and there is balance plate 11 one to be set material 111, one, end balance end 112, institute State automatic weighing machine structure 2 be mounted on balance plate 11 set material end 111, automatic weighing machine structure 2 include one be fixed on balance plate 11 The electronics weighting platform 21 of upper end and the gravity sensor 22 under electronics weighting platform 21.The balance control assembly 12 is mounted on one On a console 3 and corresponding 112 top of balance end that balance plate 11 is set, linkage of the rack gear connecting rod 123 in gear 122 Under can compress when moving down the balance plate 11 balance end 112 top surface to prevent balance plate 11 from rotating.The console 3 On be provided with the controller 4 being electrically connected with motor 121, gravity sensor 22.The reset assembly 13 is mounted on console 3 simultaneously Close to the balance end 112 of balance plate 11, reset assembly 13 includes an adjustment plate unit connecting with console 3 and is connected to Adjust the reset tension spring 131 between plate unit and the balance end 112 of balance plate 11." balance plate 11 is prevented to rotate " refers to and works as After plastic grain is added on electronics weighing platform 21, as shown in Figure 1, since the balance of balance plate 11 is broken, at this point, balance plate 11 exists State shown in FIG. 1 just has the trend rotated counterclockwise, and the piston rod as balancing control assembly 12 at this time is described in compression The top surface of the balance end 112 of balance plate 11, therefore, the rotation of balance plate 11 is prevented from.

Preferably, the plastic grain charger further includes a rack 5, the flat installation rotated by a wheel shaft 6 In the rack 5, the console 3 is mounted in the rack 5, and the console 3 is provided through for about 123 rack gear connecting rod The through-hole 31 of sliding.

Specifically, the reset assembly 13 is arranged in below the balance end 112 of balance plate 11, the adjustment plate unit includes One adjustment plate 132 for being mounted on console 3 that can be dismantled, vertically screw togather be mounted on the adjustment plate 132 adjustment bolt 133, And it is mounted on the adjusting seat 134 on 133 top of adjustment bolt, the both ends of the reset tension spring 131 are separately fixed at adjusting seat 134 With the balance end 112 of balance plate 11.

What can also be dismantled in the rack 5 is equipped with a blade guide plate 7, and the setting of blade guide plate 7 is balancing The outside for setting material end 111 of plate 11, the upper half of the blade guide plate 7 is convexly curved towards wheel shaft 6 and its curvature and flat The rotary motion trace for setting 111 periphery of material end of weighing apparatus plate 11 is consistent.

Specifically, being connect with adjustment bolt 133 of can dismantling of the adjusting seat 134, it in the specific implementation, can be such as attached drawing Shown in 1, the threaded connection slot 135 that the bottom end setting of the adjusting seat 134 is threadedly engaged with adjustment bolt 133, adjusting seat 134 Upper end pillar 136 is set, the bottom end of reset tension spring 131 is fixed to be covered on pillar 136.It is of course also possible to by the adjustment 134 inlay cards of seat are on the top of adjustment bolt 133.

The principle that the plastic grain charger weighs and feeds automatically are as follows: plastic grain falls on electronics weighting platform 21 On, the gravity sensor 22 positioned at 21 lower section of electronics weighing platform acquires and is formed weight signal, and feedback arrives controller 4, if reached Predetermined value, the control of the controller 4 balance control assembly 12 act, and the motor 121 of balance control assembly 12 starts, band movable tooth 122 rotation of wheel, the linkage rack gear connecting rod 123 of gear 122 move up, and balance plate 11 loses the compacting of oscillating tooth bar connecting rod 123, along It rotates counterclockwise, the material being placed on electronics weighting platform 21 is unloaded.The subsequent rotation of balance plate 11 resets, and controller 4 is again Control balance control assembly 12 acts, so that the rack gear connecting rod 123 of balance control assembly 12 is moved downwardly until and is compressed on balance The top surface of the balance end 112 of plate 11.Repeatedly.The plastic grain charger can accurately unload plastic grain, will not The load of extruding machine is aggravated because of the preponderance for the plastic grain being added in extruding machine, it will not be because of in investment extruding machine Plastic grain it is very few and influence production efficiency.

From above to the description of the utility model: plastic grain charger described in the utility model can be controlled automatically System puts into the weight of the plastic grain in extruding machine, and the effect of extrusion moulding will not be influenced because of extruding machine overload, Structure design is simple, facilitates manual control, improves production efficiency while guaranteeing the effect of extrusion moulding.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
