Description

A baler automatically adds metal corner protection device

technical field

The invention relates to the technical field of automatic packaging, in particular to a device for automatically adding metal corner protectors to a packaging machine.

Background technique

In the current market, in the process of bundling and transportation, the protection of fragile or valuable products is to manually place corner guards to protect the edges of the products and then tighten the bundling with packing tapes. The disadvantage of this method is that it is difficult to pack bulk products due to artificial instability To ensure the stability of the packaging, the corner guard will fall off and the product will be damaged in the later transportation.

In addition, the manual placement of metal corner guards often results in that the metal corner guards on both sides of the product are not on the same horizontal line when packaging products, and the position of the metal corner guards needs to be adjusted before packaging, which increases the time cost.

At the same time, when the edges of some products are fragile, but high-strength tensile force is required, metal corner protectors will be selected when packaging. Because the thickness of iron corner protectors is within 0.2-0.5 mm, it is necessary to develop a kind of automatic metal adding machine for balers. Corner guards.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a device for automatically adding metal corner protectors to a baler, so as to solve the problems raised in the prior art.

To achieve the above object, the present invention provides the following technical solutions:

A baler automatically adds a metal corner guard device, including a feeding component, a grabbing component, an air jet component and a packaged product. The component is connected to the air-jet component through the air-jet tube, the feeding component can send the metal corner protector to the position of the grabbing component, the grabbing component can rotate the metal corner protector to a certain angle and then transfer it to the side of the packaged product, and the air-jet component can be placed on the metal corner protector. It has been placed on the side of the packaged product and the grabbing component has left the metal corner protector, but the packing belt has not been fully tightened to prevent the metal corner protector from falling off and packing failure.

The feeding assembly includes a connecting plate, an upper and lower feeding cylinder, a quick-change silo, a fixed seat, and a front and rear feeding cylinder. The front and rear feeding cylinders are installed under the connecting plate, and the connecting plate is installed below the front and rear feeding cylinders. Feeding cylinder, a support seat is installed on one side of the upper and lower feeding cylinders. The front and rear feeding cylinders and the upper and lower feeding cylinders can be transmitted to the underside of the corner guard jaws with the metal corner guard. The upper surface of the support seat is equipped with a quick-change material bin for quick material change. The silo is fixed on the support seat by a locating pin, and the locating pin can quickly replace another quick-change silo when the metal corner guard in the quick-change silo is used up.

The grabbing assembly includes a mounting seat, a connecting bridge, an angle guard jaw and a gripping jaw transfer cylinder. The inside of the mounting seat is connected with the middle parts on both sides of the connecting bridge. The mounting seat is installed below the gripper transfer cylinder, and the connecting bridge is U-shaped. The U-shaped can make the packing tape pass through the middle of the U-shaped connecting bridge, and the two ends of the U-shaped connecting bridge are provided with corner protectors.

A magnet is installed on the inner side of the corner protector. The corner protector can extend into the quick-change material bin when the quick-change material bin rises. The corner protector absorbs the metal corner through the magnet. There are holes on the corner protector. One end of the jet pipe is connected to the inner wall of the hole, and the position of the hole is close to the corner of the corner protector.

The lower ends of both sides of the mounting base are installed with a gripper rotating cylinder. The extension of the gripper rotating cylinder can drive the rotation of the angle guard and gripper. The gripper rotating cylinder is connected to the angle guard and gripper through a connecting rod. The angle of the strap can be adjusted, and the packing belt guide plate is installed on the rear side of the mounting seat, and the packing belt guide plate can determine the moving route of the packing belt.

There are also upper limit blocks installed on both sides of the mounting seat. The upper limit blocks can limit the rotation angle of the corner guard jaws. A mechanical limit block is installed below the upper limit block on one side. The distance between the grasped component and the packaged product.

The injector assembly includes an air inlet, a one-way valve, a metal strip, a bellows and a connecting sliding ball. One end of the bellows is connected to the air inlet. The bellows can supply air to the jet through its own expansion and contraction, and the other end of the bellows is connected to the air inlet. Jet pipe, a one-way valve is installed on one side of the air inlet. The one-way valve can control the flow of gas only from the outside to the inside of the air inlet, so that the gas will not be discharged from the end of the air inlet when the bellows is squeezed. There are metal strips on the outside of the tube, and the bending arc of the metal strips can be changed. The sliding beads are connected between the metal strips. The position of the connecting sliding beads in the horizontal direction is not on the same plane. The angle between the strip and the connecting sliding ball can be adjusted. The connecting sliding ball close to the air inlet is directly fixed on one side of the air inlet, and the connecting sliding ball far from the air inlet is directly fixed on the outside of the bellows as other connections. Fixing points for sliding beads and metal bars.

The connecting sliding balls can be divided into upper connecting sliding petals and lower connecting sliding petals. The lower connecting sliding petals are provided with bolts, and the connecting sliding balls can be separated. The connecting sliding petals contact the position corresponding to the bolts with threaded holes. The upper connecting sliding flap and the lower connecting sliding flap can be simply combined or disassembled, and when the length of the corrugated tube is too long, the metal strip can be extended by connecting the sliding ball.

A sliding groove is arranged inside the connecting sliding ball, and a sliding connecting head is arranged inside the sliding groove. The sliding connecting head is convenient to adjust the angle between the metal strip and the connecting sliding ball.

The sliding connection head is provided with a connecting ring, and the position where the metal strip is connected with the connecting sliding ball is provided with a metal strip connecting ring.

Compared with the prior art, the beneficial effects of the present invention are:

1. The position of the metal corner protectors on both sides cannot be guaranteed to be consistent during packaging by manually placing the metal corner protectors, which often leads to the need to re-adjust the position of the metal corner protectors during packaging. The present invention can target different products. Place the corner protector packaging and bundling at the position where the process is confirmed to be safe to ensure that the position of each packing tape is uniform on the corner protector, and the force is uniform, saving packaging time.

2. In order to prevent the metal corner protector from being easily moved under the suction force of the magnet of the corner protector clipping claw when the strapping belt fails to tighten in time during packaging, the jet assembly of the present invention can be squeezed when the clipping claw conveying cylinder moves backwards The corrugated pipe, and the middle section of the corrugated pipe will not sag under the support of the metal strip, to prevent the corrugated pipe from being completely squeezed and the gas ejected from the jet pipe is not enough, and the metal corner guard still falls. To ensure the smooth packaging process, will not waste packaging time.
