The wrapping paper of the wrapping machine is conveyed in two steps. The longitudinal conveying of the wrapping paper of the GD series wrapping machine is divided into pre-cutting conveying and post-cutting conveying. The pre-cutting conveying is driven by a paper pulling roller to convey the wrapping paper on the conveying roller. The post-cuting conveying is conveyed to the end position of the longitudinal conveying of the wrapping paper by seven toothed belts, needs to be stopped for a short time to ensure that the wrapping paper is in a position that can be clamped by a paper pulling clamp, and is finally sent to a wrapping paper folding station by the clamp. The wrapping paper is stopped for a short time by the pressure of a paper pressing fan wheel at the end of the longitudinal conveying, and if the pressure of the fan wheel is not properly adjusted or the positioning or timing is not properly adjusted, the wrapping paper cannot be accurately stopped at the clamping position of the clamp, or the conveying of the wrapping paper is skewed, thereby causing a folding failure of the wrapping paper and reducing the operating efficiency of the equipment.

DETAILED DESCRIPTION

[0023] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following examples are only exemplary and can only be used to explain and illustrate the technical solutions of the present application, but cannot be interpreted as a limitation of the technical solutions of the present application.

[0024] As Figs. 1-3 shown, the present application provides a packaging machine transparent paper conveying device, which comprises a transparent paper conveying table 1, and a conveying toothed belt 2 is arranged on the transparent paper conveying table 1. In the present application, the source direction of the transparent paper 6 is the front end of the conveying toothed belt, and the other end is the rear end of the conveying toothed belt. In the technical solution of the present application, the position and installation of the conveying toothed belt on the transparent paper conveying table are all prior art.

[0025] A guide shaft 3 is fixedly arranged on the transparent paper conveying table near the rear end of the conveying toothed belt. In the present application, the axial center line of the guide shaft is perpendicular to the transparent paper conveying table and corresponds to the midpoint of the transverse center line of the conveying toothed belt, thereby playing a guiding role.

[0026] A transparent paper conveying sector roller 13 is arranged on the transparent paper conveying table at the front end of the conveying toothed belt. This structure is also prior art, and will not be described in detail in the present application.

[0027] A transparent paper clamp 12 is arranged on the side of the conveying toothed belt. The transparent paper clamp is used to clamp the transparent paper 6 conveyed from the conveying toothed belt and pull it to the standby position. The transparent paper clamp and the subsequent process still use the original technical solution.

[0028] The intermediate connecting plate 4 comprises a connecting plate body. A through hole is arranged in the middle of the connecting plate body. The connecting plate body is sleeved on the guide shaft 3 through the through hole. A magnet adsorption rod 11 is arranged on the lower surface of each end portion of the connecting plate body. The lower end of each magnet adsorption rod penetrates the transparent paper conveying table and extends into the electromagnet support 9 to be opposite to the electromagnet 10. When the electromagnet is electrified, a magnetic force is generated to move the magnet adsorption rod to the direction of the electromagnet. The magnet adsorption rod drives the connecting plate body to move downward to the lowest point synchronously by overcoming the restoring force of the restoring device. When the electromagnet is de-energized, the connecting plate body moves upward under the action of the restoring device to return to the original position, waiting for the next action.

[0029] In the present application, the restoring device is arranged on the guide shaft between the intermediate connecting plate and the transparent paper conveying table. In the present application, the restoring device is a restoring spring.

[0030] The two adsorption rods are parallel to each other and parallel to the moving direction of the conveying toothed belt, and a plurality of parallel adsorption pipes 7 are arranged on each adsorption rod, each adsorption pipe is communicated with the adsorption rod, the axial center line of each adsorption pipe is perpendicular to the conveying toothed belt, and the lower end of the adsorption pipe is higher than the upper surface of the transparent paper conveyed on the conveying toothed belt when each adsorption pipe drops to the lowest point, so that when the clamped transparent paper moves laterally to the conveying toothed belt, the conveying toothed belt does not need to stop, and when the next transparent paper moves on the conveying toothed belt, the previous transparent paper is already higher than the upper surface of the next transparent paper, so that the movement of the next transparent paper is not interfered, and the purpose of non-stop of the conveying toothed belt is achieved.

[0031] In the present application, the lower end surfaces of the adsorption pipes on the two sides are not in the same plane, and the lower end surface of the adsorption pipe on the side from which the transparent paper is moved out of the conveying toothed belt is lower than the lower end surface of the adsorption pipe on the other side. Fig. 1 As shown in the figure, the lower end surface of the adsorption pipe on the side close to the transparent paper clamp is lower than the lower end surface of the adsorption pipe on the side away from the transparent paper clamp, in the present application, the side close to the transparent paper clamp is called the inner side, and the side away from the transparent paper clamp is called the outer side, so that when the adsorption pipes on the two sides suck up the transparent paper, the transparent paper forms a certain inclination angle relative to the conveying toothed belt, this structure can avoid the influence or interference of the sagging of the middle part of the transparent paper on the subsequent transparent paper conveying, and because the lower end surface of the adsorption pipe on the outer side is slightly higher, when the transparent paper is pulled out of the conveying toothed belt by the transparent paper clamp, especially when the transparent paper on the side away from the transparent paper clamp is separated from the adsorption pipe on the side, the falling time of the transparent paper on the side is relatively delayed, avoiding the outer side of the transparent paper from contacting the upper surface of the conveying toothed belt or contacting the next transparent paper, thereby disturbing the flatness of the next transparent paper.

[0032] An electromagnet support 9 is arranged on the lower surface of the transparent paper conveying belt and opposite to the two ends of the middle connecting plate, and an electromagnet 10 is arranged in each electromagnet support, the electromagnet is connected with a power supply, and when the electromagnet is turned on, the middle connecting plate can be attracted to move downward, and the specific movement is as described above.

[0033] A suction pipe 8 is connected to each adsorption rod, the other end of the suction pipe is connected with a negative pressure air source, and a solenoid valve is arranged on the suction pipe.

[0034] The present technical solution also includes a controller and a photoelectric sensor, in the embodiment, the controller and the photoelectric sensor are not embodied, and the specific positions of the controller and the photoelectric sensor can be designed according to actual needs. The photoelectric sensor is used to detect whether the transparent paper on the conveying toothed belt is located at the clamping position, and all positions capable of achieving the function of the photoelectric sensor can be achieved.

[0035] The controller of the present application is respectively connected with the electromagnet, the electromagnetic valve, the photoelectric sensor and the transparent paper clamp electric signal.

[0036] Working principle:

[0037] The transparent paper is conveyed by the conveying toothed belt, the photoelectric sensor detects that the transparent paper is conveyed to the clamping position, and the detected signal is fed back to the controller, the controller controls the electromagnetic valve to open, so that the suction pipe and the suction rod are connected with the negative pressure air source through the suction pipe, at the same time, the controller controls the electromagnet to be electrified, the electromagnet adsorbs the middle connecting plate to move downward, synchronously drives the suction rod and the suction pipe to move downward, and adsorbs the transparent paper. Since the lower end of the suction pipe is higher than the upper surface of the transparent paper conveyed on the conveying toothed belt, after the transparent paper is adsorbed, the transparent paper moves upward to improve the vertical position of the transparent paper, and is separated from the conveying toothed belt. The transparent paper is stopped at the clamping position of the transparent paper clamp under the adsorption, the controller controls the transparent paper clamp to clamp the transparent paper, so that the transparent paper clamp can smoothly pull the transparent paper to the next station, the transparent paper is pulled by the transparent paper clamp, and is separated from the suction pipe. At this time, the controller controls the electromagnetic valve to close, and the electromagnet is de-energized. The middle connecting plate drives the suction rod and the suction pipe to reset under the action of the reset device, and waits for the arrival of the next transparent paper.

[0038] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme are not described in detail. It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the technical scheme of the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the technical scheme of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the specification should not be regarded as limiting the claims involved.
