Abstract

The utility model discloses a bag feeding mechanism for a bag feeding type packing machine. The bag feeding mechanism for the bag feeding type packing machine is characterized by comprising a bag feeding arm, a bag feeding swing arm, a bag clamping air cylinder and a clamping plate assembly, wherein the bag feeding arm is connected to a lower supporting shaft through the bag feeding swing arm and is connected to an upper supporting shaft through an adjusting rod, the bag feeding swing arm swings with the lower supporting shaft as a swing fulcrum and is pushed through a cam device, the clamping plate assembly is mounted on the bag feeding arm, and when the cam device pushes the bag feeding swing arm to swing, the clamping plate assembly is converted to a vertical state from a horizontal state; the clamping plate assembly is composed of a fixed clamping plate, a movable clamping plate and a clamping plate seat, the fixed clamping plate is fixedly connected with the bag feeding arm, the movable clamping plate is fixed to the clamping plate seat, the clamping plate seat is hinged to the bag feeding arm, the bag clamping motion of the movable clamping plate relative to the fixed clamping plate is pushed through the bag clamping air cylinder, and the bag clamping air cylinder is connected to the bag feeding arm. According to the bag feeding mechanism for the bag feeding type packing machine, motion of the bag feeding arm is achieved by adopting a four-bar linkage double-swing-rod structure, the structure is simple, and the motion is stable and reliable.

Description

Bag-feeding type package machine bag-loading mechanism

Technical field

The utility model relates to a kind of bag-feeding type package machine, is specifically related to a kind of bag-loading mechanism of bag-feeding type package machine.

Background technology

Bag-feeding type package machine, for the packing of particle, all kinds of special-shaped food, condiment and sauce, liquid type, is widely used on market.At present, in the packaging bag of bag-feeding type package machine, bag work completes by bag-loading mechanism, the upper bag of bag-loading mechanism need to will convert vertical laying state to after the packaging bag gripping of horizontal positioned, could allow like this machine on wrapping machine rotating disk clamp then conveying, the shortcoming of the bag-loading mechanism of prior art is: if realize packaging bag, convert the action of vertical laying state from horizontal positioned state to, structure relative complex, having stable behavior is reliably poor.

Summary of the invention

In view of the deficiency that background technology exists, the action that the purpose of this utility model is intended to provide the double swing-bar structure of a kind of employing four connecting rods to realize bag arm, simple in structure, having stable behavior failure-free bag-feeding type package machine bag-loading mechanism.

The utility model is implemented by following technical solution:

Bag-feeding type package machine bag-loading mechanism, it is characterized in that: comprise bag arm, the swing arm of upper bag, folder bag cylinder and cleat assembly, upper bag arm is connected on lower fulcrum by the swing arm of upper bag, going up in addition bag arm is connected on upper fulcrum by adjust bar, the following fulcrum of upper bag swing arm is done to swing to arrange for swing fulcrum and is promoted by cam gear, cleat assembly is arranged on bag arm, and when cam gear promotes upper bag swing arm swing, cleat assembly is transformed into vertical state from horizontality; Cleat assembly is comprised of strap, ambulatory splint and clamping plate seat, strap is fixedly connected with upper bag arm, ambulatory splint is fixed on clamping plate seat, clamping plate seat and upper bag arm are articulated and connected, the folder bag action of the relative strap of ambulatory splint is promoted by folder bag cylinder, and folder bag cylinder is connected on bag arm.

In technique scheme, adopted the double swing-bar structure of four connecting rods to realize the action of bag arm, the double swing-bar structure of four connecting rods be take upper and lower fulcrum as fixed pivot, by cam gear, promoting bag swing arm swings, in drive, bag arm is realized level and the vertically action of both direction, thereby make cleat assembly from horizontality to vertical state, coordinate the action of folder bag cylinder, realization will convert vertical laying state to after the packaging bag gripping of horizontal positioned, then allow wrapping machine disk machine clamp conveying, adopt after technique scheme, of the present utility model simple in structure, having stable behavior is reliable.

As preferably, described cam gear comprises cam, swing arm, connecting rod and crank, crank and lower fulcrum, lower fulcrum and the swing arm of upper bag form a fixed connection, small end is connected with crank, connecting rod lower end is connected with swing arm, swing arm swings and arranges, and swing arm is provided with roller and is close to cam working face, and camshaft is connected with main gear.

Accompanying drawing explanation

The utility model has following accompanying drawing:

Fig. 1 is the constructional drawing of bag-feeding type package machine bag-loading mechanism,

Fig. 2 is the left view of Fig. 1.

The specific embodiment

As shown in the figure, bag-feeding type package machine bag-loading mechanism of the present utility model, comprise bag arm 4, the swing arm 8 of upper bag, folder bag cylinder 3 and cleat assembly, upper bag arm 4 is connected on lower fulcrum 9 by the swing arm 8 of upper bag, going up in addition bag arm 4 is connected on upper fulcrum 1 by adjust bar 2, the following fulcrum 9 of upper bag swing arm 8 is done to swing to arrange for swing fulcrum and is promoted by cam gear, cleat assembly is arranged on bag arm 4, when cam gear promotes upper bag swing arm 8 swing, cleat assembly is transformed into vertical state from horizontality; Cleat assembly is comprised of strap 5, ambulatory splint 6 and clamping plate seat 7, strap 5 is fixedly connected with upper bag arm 4, ambulatory splint 6 is fixed on clamping plate seat 7, clamping plate seat 7 is articulated and connected with upper bag arm 4, the folder bag action of ambulatory splint 6 relative straps 5 is promoted by folder bag cylinder 3, and folder bag cylinder 3 is connected on bag arm 4; Described cam gear comprises cam 13, swing arm 15, connecting rod 12 and crank 11, crank 11 forms a fixed connection with the swing arm 8 of upper bag with lower fulcrum 9, lower fulcrum 9, connecting rod 12 upper ends are connected with crank 11, connecting rod 12 lower ends are connected with swing arm 15, connecting rod 12 is also undertaken drop-down by extension spring 10, swing arm 15 swings and arranges, and swing arm 15 is provided with roller 14 and is close to cam 13 driving surfaces, and camshaft is connected with main gear.

Working process of the present utility model is: when cleat assembly is horizontality (now going up bag arm is vertical state), ambulatory splint closes up the packaging bag of horizontal positioned is carried out to gripping with strap under folder bag cylinder promotes, then the connecting rod end of cam gear promotion swing arm upwarps, connecting rod upwards moves and promotes a bag swing arm by crank and clockwise rotates, under the combined action of the swing arm of upper bag and adjust bar, upper bag arm converts horizontality to from vertical state, and cleat assembly converts vertical state to from horizontality, then folder bag cylinder moves again, ambulatory splint unclamps the packaging bag of gripping, so vertically the packaging bag of state allows wrapping machine disk machine clamp then conveying, whole upper bag process action is simple, having stable behavior is reliable.
