Description

Technical Field

[0001] The present invention relates to an improved invention of express bag making equipment, and in particular to an improved invention of a gluing equipment for express bags. Background Art

[0002] With the rise of online shopping and live streaming, the demand for express packaging bags is also increasing. Existing express bags use self-adhesive glue with release paper at the bag opening for quick bonding. However, during the gluing process of the express bag, the gluing mechanism is located behind the variable speed traction roller group. Since the variable speed traction roller group transports the bag body in the form of acceleration, uniform speed, and deceleration, the glue sprayed on the bag body by the gluing mechanism is uneven, affecting product quality and increasing the cost of glue spraying. In addition, the glue is applied to the bag opening of the bag body, and no free ends are reserved on the edges of both sides of the bag opening for the release paper to be quickly lifted up, affecting the convenience of use. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a gluing device for express bags with a reasonable structure and uniform gluing.

[0004] In order to solve the above technical problems, the present invention is implemented by adopting the following technical scheme: the gluing equipment of the express bag includes a frame and a control system, and is characterized in that: the frame is provided with a bag conveying mechanism, a release paper unwinding mechanism, a gluing mechanism and a sealing and cutting mechanism, the bag conveying mechanism is sequentially provided with a measuring wheel, a uniform speed traction roller group, a material storage component and a variable speed traction roller group, the express bag and the release paper pass through the uniform speed traction roller group, the material storage component, the variable speed traction roller group and the sealing and cutting mechanism in turn, the gluing mechanism is arranged on the release paper unwinding path, and the gluing mechanism is an intermittent glue spraying mechanism, the spray gun of the gluing mechanism corresponds to the lower surface of the release paper, the release paper after gluing and the bag body are compounded on the uniform speed traction roller group, the sealing and cutting mechanism is provided with a knife edge alignment sensor, and the knife edge alignment sensor is arranged before the variable speed traction roller group.

[0005] The gluing mechanism is hydraulically driven, and the glue spraying speed is adjustable.

[0006] The gluing mechanism comprises a spray gun, a rubber hose and a glue machine. The spray gun and the glue machine are connected through the rubber hose, and a hydraulic driving structure is arranged in the glue machine.

[0007] The variable speed traction roller group is provided with two groups, front and rear, and a tensioning component is provided between the two groups.

[0008] The bag conveying mechanism is also equipped with a color mark tracking sensor, which is arranged before the uniform speed traction roller group.

[0009] The release paper unwinding mechanism is equipped with a storage structure, which includes an upper storage roller and a lower storage roller. The lower storage roller is installed on a swing arm, and the release paper is wound back and forth between the upper storage roller and the lower storage roller in sequence.

[0010] The beneficial effect of the present invention is that the improved express bag gluing equipment arranges the gluing mechanism before the uniform speed traction roller group, so that during the gluing process, the release paper is conveyed at a uniform speed to ensure uniform glue spraying, and the gluing mechanism is intermittent glue spraying, and the release paper parts on the edges of both sides of the bag opening corresponding to the bag body are not sprayed with glue, leaving a free end for the release paper to be quickly lifted up; at the same time, a knife edge alignment sensor is arranged to overcome the position deviation of the bag body during the transmission process and ensure the accuracy of the sealing and cutting position of the sealing and cutting mechanism.

[0015] The accompanying drawings show the structure of the present invention, and the relevant details are further described below in conjunction with the accompanying drawings. In this embodiment, the gluing equipment for the express bag includes a frame and a control system, and the control system can be a PLC control system. The frame is provided with a bag conveying mechanism 1, a release paper unwinding mechanism 2, a gluing mechanism 3 and a sealing and cutting mechanism 4. The bag conveying mechanism 1 is provided with a measuring wheel 5, a uniform speed traction roller group 6, a storage component 7 and a variable speed traction roller group 8 in sequence. The uniform speed traction roller group 6 and the variable speed traction roller group 8 are respectively driven by their own servo motors. The express bag and the release paper pass through the uniform speed traction roller group 6, the storage component 7, the variable speed traction roller group 8 and the sealing and cutting mechanism 4 in sequence. The gluing mechanism 3 is arranged on the release paper unwinding path, and the gluing mechanism 3 is an intermittent glue spraying mechanism. The spray gun of the gluing mechanism 3 corresponds to the lower surface of the release paper. The release paper and the bag body after gluing are compounded on the uniform speed traction roller group 6. The sealing and cutting mechanism 4 is provided with a knife edge alignment sensor 9, and the knife edge alignment sensor 9 is arranged before the variable speed traction roller group 8. The bag conveying mechanism 1 includes a plurality of guide rollers, the release paper unwinding mechanism 2 includes an unwinding wheel and its power structure, the sealing and cutting mechanism 4 includes a heat sealing cutter, and the material storage component 7 includes a material storage roller.

[0016] The working principle of the present invention is that the release paper is unwound by the release paper unwinding mechanism 2 and pulled by the uniform speed traction roller group 6, the gluing mechanism 3 sprays glue on the lower surface of the release paper, and adopts intermittent glue spraying. The release paper parts on the edges of the bag opening on both sides of the bag body are not sprayed with glue, and a free end for the release paper to be lifted is reserved. The connected bag body is pulled by the uniform speed traction roller group 6, and the release paper and the bag body after spraying glue are compounded on the uniform speed traction roller group 6. The compounded release paper and the bag body are quickly pulled by the variable speed traction roller group 8 in sequence by acceleration, uniform speed and deceleration. After reaching the position, it stops for the sealing and cutting mechanism 4 to seal and cut to form an independent express bag, wherein the knife edge alignment sensor 9 is used to sense the sealing and cutting line position of the previous connected bag body, and then the measuring wheel 5 monitors that when the bag body transmits the width of a bag body, the sealing and cutting mechanism 4 performs sealing and cutting to ensure the sealing and cutting accuracy.

[0017] As a further improved specific implementation, the gluing mechanism 3 is hydraulically driven, and the glue spraying speed is adjustable; preferably, the gluing mechanism 3 includes a spray gun, a hose and a glue machine, the spray gun and the glue machine are connected through the hose, and a hydraulic drive structure is provided in the glue machine. In order to avoid wasting the material of the bag body and the release paper during the process of the uniform speed traction roller group 6 accelerating from static to uniform speed when the gluing equipment is turned on, the glue spraying speed is adjusted to adapt to the uniformity of the glue spraying during the acceleration of the release paper, that is, the release paper is transported faster, and the glue spraying speed is also accelerated. Among them, the gluing mechanism 3 realizes the change of the glue spraying speed by adjusting the hydraulic pressure. The structure of this gluing mechanism 3 is the existing technology, and the specific working principle is not described in detail.

[0018] As a further improved specific implementation, the variable speed traction roller group 8 is provided with two groups, front and rear, and a tensioning component 11 is provided between the two groups to improve the stability of bag transmission and avoid lateral deviation.

[0019] As a further improved specific implementation, the bag conveying mechanism 1 is further equipped with a color mark tracking sensor 10, which is arranged before the uniform speed traction roller group 6. It is used to track the bag film with patterns, spray glue on the release paper according to the pattern, and then match the composite release paper and the bag.

[0020] As a further improved specific implementation method, the release paper unwinding mechanism 2 is equipped with a material storage structure 12, which includes an upper row of material storage rollers and a lower row of material storage rollers. The lower row of material storage rollers are installed on a swing arm. The release paper is wound back and forth between the upper row of material storage rollers and the lower row of material storage rollers in sequence, and the storage and tension of the release paper are automatically adjusted as the swing arm swings up and down.
