Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag conveying, in particular to a packaging bag conveying correction device. Background Art

[0002] In the process of puttingty powder packaging, the packaging bag is first filled with putty powder material by the machine, and then sealed and conveyed. Common conveying methods include conveyor belts and conveyor rollers, both of which can effectively transport the packaging bag from the filling station to other subsequent processing procedures.

[0003] The existing conveying system has a significant defect in the process of handling packaging bags: it cannot automatically correct the conveying angle of the packaging bags. After filling and sealing, whether the packaging bags are placed on the conveyor belt manually or automatically, it is difficult to ensure that the placement angle of each packaging bag is consistent. This inconsistency in placement will cause subsequent machinery to misidentify the packaging bags, causing processing delays and other problems. The common solution is to manually correct the position by standing by the conveyor belt, which invisibly increases more labor costs.

[0004] Therefore, it is necessary to set a packaging bag conveying and correction device at the conveyor belt to solve the above technical defects. Utility Model Content

[0005] The utility model aims to provide a packaging bag conveying correction device to solve the problem that the conveying angle of the packaging bag cannot be automatically corrected in the above-mentioned background technology.

[0007] Preferably, a locking groove is provided in the bottom end of each of the vertical rods, an adjustable mounting rod is installed in the locking groove, the mounting rod and the locking groove are locked in position by locking bolts respectively, and a group of clamping plates are fixedly connected to each of the locking bolts.

[0008] Preferably, the clamping sides of the clamping plates are respectively bonded with rubber plates, and two groups of the clamping plates are arranged in the gantry and are symmetrically distributed.

[0009] Preferably, two groups of connecting arms are provided, and the two groups of connecting arms are centrally symmetrically distributed about the center point of the turntable.

[0010] Preferably, a leveling mechanism for automatically correcting the flatness of the packaging bag is provided on the left side of the inner wall of the gantry, and the leveling mechanism includes a roller frame fixed to the left side of the inner wall of the gantry, and the roller frame is fixedly connected to a driving motor, and the output shaft of the driving motor is fixedly connected to a pressure roller, and the pressure roller is assembled in the roller frame.

[0011] Preferably, a mounting frame is provided below the roller frame, and the mounting frame is provided in two rows and is arranged at both ends below the pressure roller. Three groups of rollers are installed on each mounting frame, and each group of rollers is arranged in parallel. The roller frame and the mounting frame are fixed to the gantry frame by fixing angle steels.

[0013] Preferably, the width and height of the gantry are arranged according to the conveyor belt, and the gantry does not contact the conveyor belt.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the packaging bag conveying and correcting device not only realizes the rapid correction of the packaging bag angle, thereby facilitating the subsequent clamping of the robot arm, but also realizes that the material is filled in the packaging bag through the squeezing of the pressure roller, which is convenient for the subsequent stacking of the packaging bag, and the clamping plate can be flexibly adjusted;

[0015] (1) By setting a driving motor, a roller frame, a fixed angle steel, a conveyor belt, a limit rod, a fixed seat, a turntable, a servo motor, a connecting arm, a connecting block, and a sliding sleeve, when the packaging bag is filled with putty powder material and transferred to the conveyor belt, it enters from the right side of the gantry and is transmitted between the two groups of clamping plates. The servo motor drives the turntable to rotate, driving the two groups of connecting arms to pull the fixed seat to move. The fixed seat slides relatively on the outside of the limit rod through the sliding sleeve, so that the two groups of clamping plates move relatively to clamp the passing packaging bag from the side once, thereby correcting the conveying angle of the packaging bag.

Multiple sets of rollers play a limiting role to prevent the packaging bag from shifting after being squeezed, and to avoid the problem of uneven distribution of putty powder materials inside the packaging bag when the packaging bag is placed on the conveyor belt. The squeezing of the pressure rollers can fill the packaging bag with materials, which is convenient for the subsequent stacking of the packaging bags;

Rubber plates are pasted on their surfaces to avoid clamping damage to the packaging bag. The initial installation position of the clamp is adjustable, and the specific adjustment is made by loosening the locking bolts and moving the installation rod up and down in the locking groove, which has higher flexibility.

When the packaging bag is filled with putty powder material and transferred to the conveyor belt 12, it enters from the right side of the gantry 1 and is transmitted between the two groups of clamping plates 22. The servo motor 16 drives the turntable 15 to rotate, driving the two groups of connecting arms 17 to pull the fixed seat 14 to move. The fixed seat 14 slides relatively on the outside of the limit rod 13 through the sliding sleeve 19, so that the two groups of clamping plates 22 move relatively to clamp the traveling packaging bag from the side once, thereby correcting the conveying angle of the packaging bag.

[0026] Embodiment 2: A leveling mechanism for automatically correcting the flatness of the packaging bag is arranged on the left side of the inner wall of the gantry 1, and the leveling mechanism comprises a roller frame 10 fixed to the left side of the inner wall of the gantry 1, and a driving motor 9 is fixedly connected to the roller frame 10, and a pressure roller 8 is fixedly connected to the output shaft of the driving motor 9, and the pressure roller 8 is assembled in the roller frame 10, and a mounting frame 6 is arranged below the roller frame 10, and the mounting frame 6 is arranged in two rows and arranged at both ends below the pressure roller 8, and three groups of rollers 7 are respectively arranged at the mounting frame 6, and each group of rollers 7 is arranged in parallel, and the roller frame 10 and the mounting frame 6 are fixed to the gantry 1 by fixing the angle steel 11;

A group of clamping plates 22 are fixedly connected at each locking bolt 21, and a rubber plate 25 is respectively bonded to the clamping side of the clamping plate 22. Two groups of clamping plates 22 are arranged in the gantry 1 and are symmetrically distributed. The width and height of the gantry 1 are arranged according to the conveyor belt 12, and the gantry 1 does not contact the conveyor belt 12. The width and height of the gantry 1 are arranged according to the conveyor belt 12, and the gantry 1 does not contact the conveyor belt 12.

[0029] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the two sets of clamps 22 are both designed in a long strip shape, which conforms to the thickness of the packaging bag after it is filled with putty powder material.

When the packaging bag is filled with putty powder material and transferred to the conveyor belt 12, it enters from the right side of the gantry 1 and is transmitted between the two groups of clamping plates 22. The servo motor 16 drives the turntable 15 to rotate, driving the two groups of connecting arms 17 to pull the fixed seat 14 to move. The fixed seat 14 slides relatively on the outside of the limit rod 13 through the sliding sleeve 19, so that the two groups of clamping plates 22 move relatively to clamp the passing packaging bag from the side once, thereby correcting the conveying angle of the packaging bag. After the packaging bag has corrected its position, it continues to move from the double-row rollers 7 to the other side of the gantry 1. Its top is slightly squeezed by the pressure roller 8, which can level the internal putty powder material. The multiple groups of rollers 7 play a limiting role to prevent the packaging bag from shifting after being squeezed, and to avoid the problem of uneven distribution of materials inside the packaging bag when it is placed on the conveyor belt 12. The squeezing of the pressure roller 8 can fill the packaging bag with materials, which is convenient for the subsequent stacking of packaging bags.
