Abstract

The utility model discloses a discharging device of a continuous rolling plastic bag packing machine, which comprises a first roller and a second roller, wherein plastic bag rolls of continuous rolling plastic bags are placed on the first roller and the second roller; at least one of the first roller and the second roller is a power roller, the power roller drives the plastic bag roll to rotate and unreel when rotating, the emptying device further comprises a counterweight rod, and the counterweight rod is placed inside the plastic bag roll; the utility model discloses because the setting of counter weight stick, even roller rotational speed is too fast, the plastic bag book can not follow and drop between two rollers under counter weight stick's pressure is held. When the plastic bag roll continuously supplies materials and the plastic bag on the plastic bag roll continuously reduces, the friction force between the plastic bag roll and the roller is increased through the counterweight rod, the plastic bag roll and the roller can still normally rotate to unreel, the plastic bag is normally conveyed, therefore, efficient unreeling is achieved, and unreeling failure is avoided.

Description

Material feeding device of continuous roll plastic bag packaging machine

Technical Field

The utility model relates to a roll up plastic bag packagine machine's blowing device even for the blowing of plastic bag book.

Background

Patent document with publication number CN206955277U discloses a material discharging device for continuous rolling bags, which comprises a material discharging support, a power roller and an unpowered roller which are parallel to each other are mounted on the material discharging support, and a power device is also mounted on the material discharging support and drives the power roller to rotate. The emptying device adopts the structure of two rollers, the continuous rolling bag is placed on the two rollers during emptying, the power roller drives the continuous rolling bag to rotate under the driving of the power device, the unpowered roller is used for supporting the continuous rolling bag and rotates along with the continuous rolling bag, and the continuous rolling bag (plastic bag roll) can be conveniently placed and taken out by the structure device.

However, if the rotating speed of the rollers is too high, the plastic bag roll can fall off between the two rollers, and normal production operation is affected. In addition, when the plastic bag roll continuously supplies materials, the plastic bags on the plastic bag roll continuously decrease, and when the plastic bags are reduced to a small amount, the friction force between the plastic bag roll and the roller is reduced, the plastic bag roll cannot normally rotate to unreel, and the plastic bags cannot be normally conveyed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a roll up plastic bag packagine machine's blowing device even is provided, realizes the high-efficient blowing of plastic bag book.

In order to solve the technical problem, the discharging device of the continuous rolling plastic bag packaging machine comprises a first roller and a second roller, wherein plastic bag rolls of continuous rolling plastic bags are placed on the first roller and the second roller; at least one of the first roller and the second roller is a power roller, the power of the power roller is a motor, and the motor drives the power roller. The power roller drives the plastic bag roll to rotate and unreel when rotating, and the emptying device further comprises a counterweight rod which is placed inside the plastic bag roll.

In order to prevent the position of the plastic bag roll from shifting when the plastic bag roll is rotated and unreeled, two ends of the plastic bag roll are provided with limiting rods. The position of the limiting rod is adjustable, so that the limiting rod can be adjusted according to the width of the plastic bag roll. Further, as preferred, the counter weight stick is the U type, the opening part of U type counter weight stick has the connecting piece of connecting U type counter weight stick both ends, the gag lever post is arranged in U type counter weight stick. The connecting piece can slide to the middle part direction of counter weight stick for U type counter weight stick and gag lever post combine closely, prevent that the plastic bag book from upwards beating, adopt lighter counter weight stick, alright realize the efficiency of heavier counter weight stick.

The utility model discloses because the setting of counter weight stick, even roller rotational speed is too fast, the plastic bag book can not follow and drop between two rollers under counter weight stick's pressure is held. When the plastic bag roll continuously supplies materials and the plastic bag on the plastic bag roll continuously reduces, the friction force between the plastic bag roll and the roller is increased through the counterweight rod, the plastic bag roll and the roller can still normally rotate to unreel, the plastic bag is normally conveyed, therefore, efficient unreeling is achieved, and unreeling failure is avoided.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a schematic view of the present invention.

Fig. 2 is a schematic view of the plastic bag roll of the present invention.

Detailed Description

As shown in fig. 1 and 2, the discharging device of the continuous rolling plastic bag packaging machine comprises a discharging frame 1, a first roller 2 and a second roller 3 are mounted on the discharging frame 1, and a plastic bag roll 8 of a continuous rolling plastic bag is placed on the first roller 2 and the second roller 3. The first roller 2 is a power roller, the power of the power roller is a motor 4, the motor 4 drives the power roller to rotate, and the second roller 3 is an unpowered roller. When the first roller 2 rotates, the plastic bag roll 8 is driven to rotate and unreel.

The two ends of the plastic bag roll 8 are provided with limiting rods 5, so that the position of the plastic bag roll 8 is prevented from deviating when the roll is rotated and unreeled.

The discharging device further comprises a counterweight rod, and the counterweight rod is placed inside the plastic bag roll 8. In this way, even if the rollers rotate at too high a speed, the roll 8 of plastic bags will not fall out between the two rollers under the pressure of the counterweight rod. When the plastic bag roll 8 continuously supplies materials and the plastic bag on the plastic bag roll 8 continuously reduces, the friction force between the plastic bag roll 8 and the roller is increased through the counterweight rod, the plastic bag roll 8 and the roller still normally rotate to unreel, and the plastic bag is normally conveyed, so that efficient unreeling is realized, and unreeling failure is avoided.

The counterweight rod is U-shaped, the opening of U-shaped counterweight rod 6 is provided with a connecting piece 7 connected with two ends of U-shaped counterweight rod 6, and the limiting rod 5 is arranged in U-shaped counterweight rod 6, as shown in figure 1. Connecting piece 7 can slide to the middle part direction of U type counter weight stick 6 for U type counter weight stick 6 and gag lever post 5 zonulae occludens prevent that the plastic bag from rolling up 8 and upwards beating, like this, adopt lighter counter weight stick, alright realize the efficiency of heavier counter weight stick.

The above-mentioned embodiment does not limit the utility model in any way, and all the technical solutions that adopt the mode of equivalent replacement or equivalent transform to obtain all fall within the protection scope of the utility model.
