Description

Technical Field

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

[0002] In the process of rolling paper production, the paper roll needs to be placed in the packaging bag and then sealed by plastic sealing. The existing fully automatic rolling paper packaging device uses the bag opening mechanism to open the packaging bag, and the push arm pushes the neatly arranged paper rolls into the packaging bag. Then, the push arm pushes the paper package to the sealing mechanism for sealing; because the rolling paper has a certain elasticity, the paper roll will be pressed when it is placed in the packaging bag, but due to the elasticity of the paper roll itself, the paper roll will naturally rebound in the process of the push arm pushing the paper package to move to the sealing mechanism. After the paper package is sealed, it is very loose and will deform during the transportation process, that is, the two ends of the paper package droop, which is not beautiful and affects the later sales. The existing semi-automatic packaging device usually arranges the rolling paper in a matrix form, opens the packaging bag, pushes the push plate into the packaging bag, and then manually moves the paper package to the plastic sealing process. In this way, before plastic sealing, the staff will squeeze the paper package to make the paper roll in a compacted state, so the packaged paper package is tight and beautiful, but this working method requires a lot of manpower, low efficiency and high cost. Utility Model Content

[0003] The utility model aims to provide a packaging device to solve the problem that the existing packaging device cannot solve the paper roll rebound problem, the paper package after packaging is not tight and beautiful, which affects the later transportation and sales.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses a packaging device, comprising a working platform, a mounting plate is arranged above the working platform, a material pushing mechanism is arranged on the side of the mounting plate, a bag opening mechanism is arranged on the top surface of the working platform, a sealing mechanism is arranged on the front side of the bag opening mechanism, and a bag pressing mechanism is arranged on the front side of the sealing mechanism.

[0006] Furthermore, the pushing mechanism includes a push arm operating servo motor, which is arranged on the top surface of the mounting plate near the rear side, and a push arm is arranged below the mounting plate. The push arm operating servo motor drives the push arm to move forward and backward through a first transmission component, and a follower suction port servo motor is arranged on the top surface of the mounting plate, and a follower suction port is arranged below the mounting plate. The follower suction port servo motor drives the follower suction port to move forward and backward through a second transmission component, and the follower suction port is connected to the vacuum pumping device through an air duct, a gas flow channel is arranged inside the push arm, and an air suction hole is arranged on the push plate of the push arm, and the vacuum pumping device is connected to the air suction hole through the air duct and the gas flow channel.

[0007] Furthermore, the first transmission assembly includes a first active synchronous wheel, which is mounted on the output shaft of the servo motor running the push arm. A first driven synchronous wheel is arranged on the bottom surface of the mounting plate near the front side. The first active synchronous wheel and the first driven synchronous wheel are connected by a first synchronous belt transmission, and the push arm is arranged on the first synchronous belt.

[0008] Furthermore, the second transmission assembly includes a second active synchronous wheel, which is mounted on the output shaft of the follower suction port servo motor, and a second driven synchronous wheel is provided on the top surface of the mounting plate near the front side, and the second active synchronous wheel and the second driven synchronous wheel are connected by a second synchronous belt transmission, and the follower suction port is provided on the second synchronous belt.

[0012] Furthermore, a bag pressing brush is arranged between the bag opening mechanism and the sealing mechanism.

[0013] Compared with the prior art, the beneficial technical effects of the utility model are:

[0014] The utility model utilizes a bag opening mechanism to open the packaging bag, utilizes a push arm to push the neatly arranged paper roll into the packaging bag, and a follower suction port waits for the push arm near the bag opening mechanism. After the push arm is connected with the follower suction port, a vacuum treatment is performed on the packaging bag. Thereafter, the push arm and the follower suction port move forward together until the paper bag is sent to the sealing mechanism for sealing. The entire packaging process is completed in one go without manual operation, with a high degree of automation and high work efficiency. The push arm and the follower suction port move together, and the inside of the paper bag is kept vacuumed from the time when the paper roll is loaded into the packaging bag to the time when the paper bag is sealed. The vacuum state makes the packaging bag always close to the surface of the paper roll. In addition, the thrust of the push plate keeps the paper roll in a compressed state until the sealing is completed. The thrust and vacuum suction disappear, and the paper roll can expand slightly. Since the sealing work has been completed at this time, the expansion force between the paper rolls will only make the entire paper package tighter and the appearance smoother, which is convenient for later transportation; the follow-up suction port is positioned in a fixed position, so that the roll paper has no rebound action and the tightness is stable, which solves the problems of loose and misaligned finished paper after bagging, replaces the previous manual compression, saves labor, reduces costs and improves efficiency.

[0024] Specifically, the first transmission assembly includes a first active synchronous wheel 3, which is installed on the output shaft of the push arm running servo motor 1, and a first driven synchronous wheel 4 is installed on the bottom surface of the mounting plate 11 near the front side.

[0031] Take the paper roll packaging as an example to illustrate the working process of the utility model:

[0032] First, multiple paper rolls are conveyed to the working platform 12, and the push arm operation servo motor 1 is started. The push plate 202 of the push arm 2 pushes the multiple paper rolls to move forward. At this time, the bag opening mechanism 13 has already opened the packaging bag.

The follower suction port 7 moves forward together with the push arm 2, and the push plate 202 pushes the paper bag to continue to move forward. During this process, the packaging bag is always kept in a vacuum state; when the paper bag moves to the bottom of the sealing mechanism, the push arm 2 is retracted, and the sealing mechanism seals the paper bag. The push arm operation servo motor 1 rotates in the opposite direction, driving the push arm 2 to move backward to the initial position to prepare for the next work.

[0033] In the present invention, from the time when the paper roll is loaded into the packaging bag to the time when the paper bag is sealed, the inside of the paper bag is always kept in a vacuum state, so that the packaging bag is always close to the surface of the paper roll, and the thrust of the push plate keeps the paper roll in a compressed state until the sealing is completed, the thrust and vacuum suction disappear, and the paper roll can expand slightly. Since the sealing work has been completed at this time, the expansion force between the paper rolls will only make the entire paper bag tighter and the appearance smoother, which is convenient for later transportation. The present invention solves the major problems of non-compact packaging and inconsistent long and short packages of fully automatic middle packaging equipment by setting a pushing mechanism. The pushing mechanism described in the present invention can be applied to various fully automatic models, including a series of fully automatic middle packaging equipment such as a multi-row fully automatic middle packaging machine for round rolls, a fully automatic middle packaging machine for horizontal flat rolls, a fully automatic middle packaging machine for paper drawing, and a fully automatic middle packaging machine for bottom drawing.
