Description

A semi-automatic box sealing machine

technical field

The invention relates to the field of article carton packaging equipment, in particular to a semi-automatic box sealing machine.

Background technique

The carton sealing machine uses instant tape to seal the cartons. It is economical, fast, and easy to adjust. It can complete the upper and lower sealing actions at one time. It can also use printing tape to improve the product image. It is the first choice for automatic packaging companies. The key component of the sealing machine is the drive motor. The more powerful the motor, the better. Features of the carton sealing machine: light and durable, easy to operate; side belt drive, suitable for narrow cartons; upper and lower belt drive. It is suitable for higher cartons; the carton sealer is the core energy-consuming part of the system, and the most direct and effective means to improve the system efficiency is to improve the efficiency of the carton sealer, which will significantly reduce the energy consumption of the system. At the same time, this can also avoid a large increase in material consumption caused by only taking measures on the system (such as blindly increasing the area of the heat exchanger, etc.). In recent years, with the increasingly severe energy shortage in the world, various countries have paid more and more attention to energy conservation, and put forward higher and higher requirements for the efficiency of energy-consuming products. Due to the existence of various losses such as friction, leakage, harmful heat transfer, motor loss, flow resistance, noise and vibration, the actual efficiency of the sealing machine is far lower than the theoretical efficiency. Therefore, in theory, any measure that can reduce any kind of loss can improve the efficiency of the box sealer. This objective fact has led to a wide range and direction of energy-saving research on box sealers, with various research topics and research results.

In the early days, the material used for the suspension mechanism of the tape sealing machine was I-beam; the self-weight was very large, and a lot of manpower and material resources were required for installation and transportation. At the same time, the forward-extending mechanism is in the form of I-beam cantilever, and its stress stability is far less portable and stable than the cable-type generally used at present. Today's tape sealing machine manufacturing industry is also booming like mushrooms, and the structure, technology and process of tape sealing machines have been greatly improved and improved.

When working, the carton automatic unfolding device is set above the carton clamping device, and the carton automatic unfolding device is suspended under the upper suspension device, so as to facilitate the downward movement of the carton automatic unfolding device. The vacuum suction cup absorbs the carton and cooperates with the carton clamping device to finish fixing and open the carton. The carton is moved to the working range of the automatic sealing mechanism by the load moving device. The automatic sealing mechanism uses the automatic sealing moving device to obtain an optimum sealing point, which also satisfies the need to adapt to the packaging of cartons of different specifications.

The carton automatic unfolding device is set above the carton clamping device, the carton is placed on the loading plate, and the motor drives the radial movement of the splint through the movement of the lead screw. The splint is close to the loading plate, and the stability of the carton clamping device is improved through the uniform rotation of the lead screw.

The load seat is installed on the base, connected with the base by a screw nut, and driven by the motor, it can move axially and horizontally; the carton clamping device is installed on the load seat, which is used for folding and tightening the carton.

The vacuum suction cup is connected with the cylinder and hung above the loading seat. When the box folding starts, the cylinder stretches to make the vacuum suction cup close to the carton. After the vacuum suction cup absorbs the carton, the cylinder retracts to slightly lift the upper part of the carton. The device and the motor work at the same time. The carton clamping device starts to clamp the carton with the lifting of the upper part of the carton, so that the carton continues to fold according to the original movement. Driven by the screw, the loading seat moves axially at a uniform speed at the same time to complete the folding action, and the vacuum suction cup stops. When working, the carton clamping device maintains the clamping state, and the loading seat continues to move axially. Under the action of the rear guide rod, the carton boards are folded inwardly to complete the box folding action. During the folding process, the adsorption force of the vacuum suction cup is not enough to completely fold the carton, so the function of the vacuum suction cup is to absorb the carton, and when the cylinder retracts, it drives the upper part of the carton to lift up at an angle, and then no longer absorbs the carton, but still with the When the carton is folded, it is raised and retracted slowly, and then the carton clamping device pushes the carton to make the carton folded to 90 degrees, and finally moves to the set value to complete the folding and clamping action of the carton.

The carton passes through the first roller, which is connected to the first connecting rod. After being pressed, the first roller drives the first connecting rod to rotate counterclockwise, and the first connecting rod passes through the middle connecting rod to drive the second connecting rod to rotate counterclockwise. , the spring generates tension to prevent the movement of the middle link, and at the same time the tension is transmitted to the first link and the second link through the middle link, which also produces resistance to the rotation of the first link and the second link, so that the first roller Press the surface of the carton with the second roller. At this time, the adhesive tape is also pressed on the carton by the first roller and the second roller. When the tail of the carton leaves the first roller, the second roller is still pressed on the surface of the carton. When the tail of the carton leaves After the second roller, under the action of the spring, the first roller and the first connecting rod rotate clockwise quickly, and under the transmission of the intermediate connecting rod, the second roller and the second connecting rod quickly move counterclockwise, and the blade follows the second The rollers fall down quickly, breaking the tape, and the last part of the tape is pressed against the side of the carton under the action of the second roller to complete the sealing action.

The automatic sealing moving device uses a horizontal cylinder to move the sealing device laterally, and a vertical cylinder to move the sealing device longitudinally. Through the control system to meet the packaging of cartons of different specifications.

In the load moving device, the large motor drives the rotation of the large lead screw, and the large lead screw drives the axial movement of the carton clamping device. The large motor, large lead screw and carton clamping device are fixed by the bottom plate to meet the stable transportation. The feature of the automatic box folding and sealing machine is that it does not require manual operation during the working process. After the box folding action is completed, the box can be sealed directly without manual flipping, so that the front side of the carton can be turned upside down to complete the box sealing, which shortens the working time and improves the quality of the carton. improved packaging efficiency.

The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, without departing from the inventive concept of the present invention, some modifications and improvements can also be made, and these all belong to the present invention. protection scope of the invention.
