Description

Modified plastic discharging control and packaging integrated device

Technical Field

The utility model relates to the field of packaging, concretely relates to integrative device of modified plastic ejection of compact control, packing.

Background

Need pack after the plastic granules shaping, at present use the wrapping bag to pack usually, during the packing, open the wrapping bag and relative back with the discharge gate of hopper, fashioned plastic granules falls into in the wrapping bag from the discharge gate, after treating to fill with plastic granules in the wrapping bag, takes off the wrapping bag from the hopper and shifts to the banding process and accomplish plastic granules's packing to the wrapping bag promptly. The existing hopper is high, if the packaging bag is directly placed on the ground, a certain distance is reserved between the opening of the packaging bag and the discharge hole, plastic particles fall out of the discharge hole, and the plastic particles are easy to splash outside the packaging bag before falling into the packaging bag, so that waste is caused; in addition, only place the wrapping bag below the hopper and also can't guarantee that wrapping bag and discharge gate align, under the circumstances of wrapping bag skew, plastic granules also can drop outside the wrapping bag. If the packaging bag is sleeved at the lower end of the hopper upwards, the packaging bag needs to be lifted upwards manually, the downward pressure on the packaging bag is gradually increased along with the increase of plastic particles in the packaging bag, and the packaging bag is difficult to position manually.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a modified plastic ejection of compact control, integrative device of packing to fix a position the wrapping bag.

In order to achieve the above purpose, the utility model adopts the following technical scheme: modified plastics ejection of compact control, integrative device of packing, including driving piece and two fixed units, two fixed units all include two centre gripping subassemblies, and the centre gripping subassembly includes swing piece and briquetting, and the driving piece is connected with swing piece and is used for the swing of drive pendulum rod, and the briquetting is fixed on swing piece, and two briquetting of one of them fixed unit are relative with two briquetting of another fixed unit respectively.

The beneficial effect of this scheme does:

1. when packing, two relative centre gripping subassemblies can carry out the centre gripping to the wrapping bag, make the wrapping bag can overlap the lower extreme at the hopper, avoid plastic granules to fall to the wrapping bag and lead to extravagantly outward. In addition, the plastic particles are not required to be lifted upwards manually in the process of being added into the packaging bag, so that the workload is reduced, and the operation is convenient.

2. When the installation, on the device in this scheme located the hopper, two centre gripping subassemblies of same fixed unit were located the both sides of hopper respectively this moment, when fixing the wrapping bag, two centre gripping subassemblies of two fixed units carry out the centre gripping to the both ends of wrapping bag respectively, and the briquetting can not exert pressure to the hopper this moment, can avoid the hopper to warp and lead to the discharge gate ejection of compact not smooth.

Furthermore, the fixing unit also comprises a connecting rod, and two ends of the connecting rod are respectively fixed on the swinging pieces of the two clamping components.

The beneficial effect of this scheme does: the connecting rod is connected with the swing piece of two centre gripping subassemblies, can make two swing piece synchronous oscillations, realizes the centre gripping of wrapping bag both sides simultaneously and relaxs, and after plastic granules fell into the wrapping bag completely, the wrapping bag can keep the horizontality and fall downwards, avoids the wrapping bag skew and leads to the plastic granules in the wrapping bag to spill.

Furthermore, the swinging piece comprises a swinging rod and a fixed rod, the two ends of the connecting rod and the driving piece are both connected with the swinging rod, and the two ends of the fixed rod are respectively fixed on the connecting rod and the pressing block.

The beneficial effect of this scheme does: when the pressing block is used for clamping the two sides of the packaging bag, the middle part of the packaging bag is pressed on the hopper by the pressing belt, so that gaps between the packaging bag and the hopper are further avoided, and plastic particles are prevented from falling out.

Further, the pressing belt is an elastic belt.

The beneficial effect of this scheme does: when the elastic band is stretched, the pressure of the elastic band on the packaging bag is larger, and the positioning effect on the middle part of the packaging bag is better. Compared with a hard pressing structure, the elastic belt in the scheme is flexible, so that the opening part of the packaging bag can be pressed on the hopper according to the shape of the lower end of the hopper, the position of the packaging bag opposite to the pressing belt is completely attached to the hopper, and the elastic belt is suitable for hoppers with different shapes; and in the use, even the hopper lower extreme takes place to warp and also guarantees that the wrapping bag can laminate with the hopper.

Further, the section of the pressing block along the horizontal direction is annular.

The beneficial effect of this scheme does: compare with flat-plate, two lateral walls of briquetting in this scheme can be perpendicular to two other lateral walls, when carrying out the centre gripping to the wrapping bag, the vertically lateral wall can support the lateral wall of briquetting and wrapping bag contact, avoids the lateral wall of briquetting and wrapping bag contact to take place bending deformation, so can make the briquetting keep better centre gripping effect to the wrapping bag.

Further, the fixed unit below is equipped with ejection of compact unit, and ejection of compact unit includes conveyer belt and railing, and the conveyer belt side direction is located along vertical to the railing, and the length direction of railing edge conveyer belt extends.

The beneficial effect of this scheme does: after adding plastic granules in the wrapping bag, relax the briquetting, the wrapping bag can be on the conveyer belt of whereabouts under the action of gravity, and the railing can carry on spacingly to the wrapping bag this moment, avoids the wrapping bag to empty, leads to the plastic granules in the wrapping bag to spill.

Further, rotate on the pendulum rod and be connected with the fixed block, be equipped with the bar groove on the fixed block, bar inslot lateral sliding is connected with the control lever, and the both sides of fixed block all are equipped with limiting plate and two limiting plates and all fix on the control lever, and the driving piece is connected with the one end that the fixed block was kept away from to the control lever and is used for drive control lever along endwise slip.

The beneficial effect of this scheme does: the control lever in this scheme carries out linear motion, and driving piece such as cylinder, pneumatic cylinder or linear actuator can be adopted to the driving piece this moment, compares with the motor, and above-mentioned power piece can make the briquetting bigger to the clamping-force of wrapping bag, improves the centre gripping effect to the wrapping bag.
