Abstract

The invention discloses a transverse sealing and cutting device for a granule packaging machine. The transverse sealing and cutting device comprises two vertical guide rods, wherein a movement seat capable of sliding up and down is arranged on the two vertical guide rods; two sets of symmetric clamping claws are arranged on two sides of the movement seat respectively; the outer ends of the clamping claws are connected to two ends of a jacking rod through pin shafts; the middle parts of the clamping claws are arranged on the two guide rods through shaft holes in a rotatable manner; cutter holders are correspondingly arranged on the side faces between the two clamping claws; a transverse cutter with opposite cutting edges is arranged on one cutter holder; a connecting rod is upwards arranged on the middle part of the upper face of the movement seat; the upper end of the connecting rod is connected with a crank shaft in a rotatable manner; one end of the crank shaft is horizontally arranged on the tops of the two guide rods through a bearing pedestal; and the other end of the crank shaft is provided with a driving wheel on the outer side of the guide rod. The transverse sealing and cutting device is particularly suitable for packaging small-capacity back-sealing bags, and has the advantages of high sealing and cutting quality and high efficiency.

Description

A kind of particles packing machine horizontal sealing cutting apparatus

Technical field:

The present invention relates to the mechanical engineering element, particularly a kind of low capacity back of the body envelope particles packing machine horizontal sealing cutting apparatus of packing fast that is applicable to.

Background technology:

Present particles packing machine horizontal sealing cutting apparatus has two kinds, and a kind of is continuous rotary, and another kind is the open-close type at intermittence.Continuous rotary horizontal sealing cutting apparatus is on two horizontal sealing axles, to be engaged with a pair of driven wheel; On two horizontal sealing axles, also be separately installed with a vertically sealed roller that rotates in opposite directions; Updrift side between two vertically sealed rollers is equipped with a vertical sealing roller, and symmetry is evenly equipped with four envelope knife assemblies respectively on two vertically sealed rollers.The shortcoming that this structure exists is that the time effect too short, back of the body envelope of cutting because of envelope is relatively poor, and the batch (-type) sealing-cutting device is that a cover actuating device is installed respectively on two vertically sealed rollers, though that the effective envelope of back of the body envelope is cut efficient is low.

Summary of the invention:

The purpose of this invention is to provide a kind of envelope particles packing machine horizontal sealing cutting apparatus that quality is good, efficient is high of carrying on the back.

Technical scheme of the present invention is accomplished as follows; It includes two vertical type guide rods, it is characterized in that: the kinematic nest that can slide up and down is installed on two vertical type guide rods, is separately installed with the jaw of a cover symmetry in the both sides of kinematic nest; Each outer end of overlapping jaw is connected the two ends of a push rod respectively with bearing pin; The middle part of each jaw is rotatably installed on two guide rods by axis hole respectively, and correspondence is equipped with a tool rest respectively on the side between two jaws, and a revolving knife that the edge of a knife is relative is installed on a tool rest; The middle part upwards is equipped with a connecting rod on kinematic nest; Small end is rotatably connected to a crank shaft, and an end of crank shaft is installed in the top of two guide rods by the bearing seat level, in the guide rod outside drive wheel is installed at an end of crank shaft.This device is specially adapted to low capacity back of the body bagging and packaging is had envelope and cuts the advantage that quality is good, efficient is high.

Description of drawings:

Fig. 1 is a structural representation of the present invention; Fig. 2 is the A-A cutaway view of Fig. 1; Fig. 3 is the B-B cutaway view of Fig. 1.

The specific embodiment:

Describe embodiment in detail in conjunction with above accompanying drawing; This device is that the kinematic nest 3 that can slide up and down is installed on two vertical type guide rods 7; Be separately installed with the jaw 8 of a cover symmetry in the kinematic nest both sides, each outer end of overlapping jaw is connected the two ends of a push rod 6 respectively with bearing pin 5, and the middle part of each jaw is rotatably installed on two guide rods by axis hole respectively; Correspondence is equipped with a tool rest 9 respectively on the side between two jaws; A revolving knife 10 that the edge of a knife is relative is installed on a tool rest, and the middle part upwards is equipped with a connecting rod 4 on kinematic nest, and small end is rotatably connected to a crank shaft 2; The crank shaft two ends are installed in the top of two guide rods by the bearing seat level, in the guide rod outside drive wheel 1 are installed at an end of crank shaft.Make crank shaft when revolution by the driven by motor drive wheel during work, kinematic nest is done straight reciprocating motion, drives push rod and does straight reciprocating motion; Make the jaw swing, when jaw was opened, the film tube was in advance through bag length of jaw; Begin to be synchronized with the movement, jaw is being followed the film tube when descending, and push rod ejects rapidly; The top puts in place static a period of time of back, and the jaw revolution is closed, begins to seal and cuts.Before jaw moved to limit position, bottom, push rod was withdrawn rapidly, got back to behind the position still staticly, and up to next action cycle, jaw is opened upward movement, gets back to initial point position, top.Accomplish an action cycle.Whole horizontal sealing is cut in the process, and the motion of film tube is continuous, and jaw moves downward in the process and to accomplish envelope and cut action following the film tube, cuts the time so have long envelope, guarantees that envelope cuts packaging quality, and can realize high-speed packaging.
