[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1:

[0027] Reference Figure 1-4 , an automatic film-loading device for a bean filling packaging machine, comprising a frame 1, on which a driven roller 101 is rotatably connected, and also comprising: two groups of telescopic push rods 102, both of which are fixedly connected to the frame 1, and the telescopic ends of the telescopic push rods 102 pass through the frame 1, and the telescopic ends of the two groups of telescopic push rods 102 are arranged opposite to each other; two groups of wire harness sensors 104, respectively fixedly connected to the telescopic ends of the telescopic push rods 102, and the wire harness sensors 104 are used to detect that the center of the packaging film is located between the telescopic ends of the two groups of telescopic push rods 102; a telescopic cylinder 3, fixedly connected to the frame 1, and a support plate 4 is fixedly connected to the telescopic end of the telescopic cylinder 3, and the support plate 4 is used to place the packaging film, and a chip is set to record data and control various devices.

[0028] One of the wire harness sensors 104 in the present device is a wire harness transmitting end, and the other is a receiving end. When in use, the packaging film to be installed is placed on the support plate 4, and then the height of the packaging film can be adjusted by the telescopic cylinder 3 until the center of the packaging film and the center of the telescopic end of the telescopic push rod 102 are at the same level. The specific operation process is that the packaging film does not block the wire harness initially, and when the packaging film moves up, the wire harness is blocked, and when it moves up again, the wire harness will be received again. At this time, the position information of the telescopic end of the telescopic cylinder 3 is recorded, and the telescopic cylinder 3 continues to move. When the wire harness is blocked again, the telescopic cylinder 3 stops moving and records the position. At this time, the distance recorded in the middle is the center of the packaging film. Move up again by half the distance of the recorded position to reach the center of the circle. At this time, the telescopic push rod 102 is extended and can be inserted into the center of the circle to complete the automatic installation of the packaging film without manual holding for installation.

[0029] Then the film on the packaging film can be torn off, wound on the driven roller 101, and the film is installed on the bean filling packaging machine to package the bean filling.

[0030] When in use, it is also necessary to cooperate with the limiting device of the packaging machine. The limiting device is two movable plates or rollers, which are used to hold the two ends of the packaging film to prevent it from moving left and right, so that it can only rotate stably.

[0031] Embodiment 2:

[0032] Reference Figure 4-6 , an automatic film-loading device for a bean filling packaging machine, which is basically the same as Example 1, and further: a launching rod 201 and a receiving rod 202 are fixedly connected to a frame 1, and a packaging film is located between the launching rod 201 and the receiving rod 202, a plurality of groups of air outlet holes 2011 are arranged on the launching rod 201, and an air pipe 2012 is arranged in the launching rod 201, the air outlet holes 2011 are communicated with the air pipe 2012, and the air outlet end of the air outlet holes 2011 faces the receiving rod 202, and a plurality of groups of grooves are arranged on the receiving rod 202, and the grooves correspond to the positions of the air outlet holes 2011 one by one, and an air flow sensor 2021 is connected in the grooves, a bracket 103 is fixedly connected to the frame 1, a telescopic cylinder 3 is installed on the bracket 103, and a connecting pipe 203 is connected to the frame 1, and the connecting pipe 203 is used to supply air to the air pipe 2012.

[0033] After the packaging film is installed, the film can be passed through between the transmitting rod 201 and the receiving rod 202, and then a small air pump is installed. The air outlet end of the air pump is connected to the connecting pipe 203, and air is blown at this time. At this time, the gas blown out of the air outlet 2011 will be blocked by the film and cannot be detected by the airflow sensor 2021. When there is a hole in the film, the gas will pass through the film and contact the airflow sensor 2021. At this time, it can be known that there is damage and packaging is stopped. In order to reduce the contamination of the bean filling caused by the damage of the packaging, this section of the film can be cut off and re-installed.

[0034] There may be a situation where the membrane is small and some airflow sensors 2021 have been receiving airflow from the beginning. At this time, the built-in chip shields these sensors.

[0035] The utility model can move the packaging film up and down through the cooperation of the telescopic cylinder 3 and the support plate 4, and at the same time determine whether it is located between the telescopic ends of the telescopic push rod 102 through the wire harness sensor 104. Then the packaging film can be restricted by the telescopic push rod 102, so that the packaging film can be self-delivered, the labor intensity of the staff is reduced, and it is easy to use.

[0036] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
