Description

Technical Field

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

[0002] Waste film recycling refers to the process of collecting, processing and reusing waste plastic films (such as agricultural films, packaging films, industrial films, etc.). Plastic films are widely used in packaging, agriculture, industry and other fields, and generate a large amount of waste after use. Therefore, waste film recycling equipment is needed to collect the waste films.

[0003] The waste film recovery mechanism in current double-sided sealing systems is fixed below the side seal mechanism. If the side seal mechanism adjusts as the product width changes, the adjusted side seal mechanism and the waste film recovery mechanism will become misaligned. This requires at least two corner idler wheels to turn the waste film to the film collection tray before it can be collected. During this process, film jams and breakages may occur. Therefore, a waste film recovery device that can solve these film jam and breakage problems is urgently needed. Utility Model Content

[0004] In order to solve the problems mentioned in the above background technology, a waste film recovery device is proposed. The technical solution adopted by the present utility model is as follows: a waste film recovery device, including a conveying platform for conveying products, a film sealing mechanism with adjustable width and continuous sealing, a waste film recovery mechanism that can move synchronously and adaptively with the film sealing mechanism, and a movable guide rail and a connecting plate for moving the waste film recovery mechanism; the waste film recovery mechanism is slidably installed on the movable guide rail, and the waste film recovery mechanism is fixedly connected to the film sealing mechanism through the connecting plate, and the conveying platform is fixedly installed in the middle position of the film sealing mechanism on both sides.

[0005] Furthermore, the waste film recovery mechanism includes a base, a drive motor, a transmission chain, a micro switch, a rocker arm and a film collection disk; the drive motor is fixedly mounted on the upper surface of the base, and the output shaft of the drive motor is transmission-connected to the transmission chain.

[0006] Furthermore, the transmission chain is connected to the rocker arm and the film collecting disk by chain shaft transmission, and the rocker arm is arranged between the transmission chain and the film collecting disk.

[0007] Furthermore, a roller with wide sides and thin middle is provided at one end of the rocker arm, and a semicircular handle is provided at the other side. A reaction bar of a micro switch is provided at the upper end of the outer surface of the semicircular handle and contacts the semicircular handle.

[0008] Furthermore, the micro switch is fixedly arranged on the outer cover of the transmission chain and is located at the upper end of the rocker arm.

[0009] Furthermore, a servo motor is provided in the conveying platform, and the surface of the conveying platform is a belt driven by the servo motor.

[0010] The beneficial effects of the waste film recovery device of the utility model are as follows:

[0011] 1. By using a connecting plate to fix the film sealing mechanism and the waste film recovery mechanism, the waste film recovery mechanism and the film sealing mechanism can move synchronously, solving the problem of waste film turning, resulting in film jamming and film breakage in traditional waste film recovery mechanisms.

[0012] 2. By setting up a drive motor, a micro switch and a rocker arm structure in the waste film recovery mechanism, and utilizing the functional relationship between the rocker arm and the waste film and the coordination between the rocker arm and the micro switch, the operation and stop mode of the drive motor can be adjusted to achieve the effect of adaptive film collection and solve the problem of possible film breakage.

[0019] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-5As shown, a waste film recovery device includes a conveying platform 1 for conveying products, a film sealing mechanism 2 with adjustable width and continuous sealing, a waste film recovery mechanism 3 that can move synchronously with the film sealing mechanism 2 and is adaptive, and a movable guide rail 4 and a connecting plate 5 for moving the waste film recovery mechanism 3; the waste film recovery mechanism 3 is slidably installed on the movable guide rail 4, and the waste film recovery mechanism 3 is fixedly connected to the film sealing mechanism 2 through the connecting plate 5, and the conveying platform 1 is fixedly installed in the middle position of the film sealing mechanism 2 on both sides.

[0021] The waste film recovery mechanism 3 includes a base 301, a drive motor 302, a transmission chain 303, a micro switch 304, a rocker arm 305 and a film collection disk 306; the drive motor 302 is fixedly installed on the upper surface of the base 301, and the output shaft of the drive motor 302 is connected to the transmission chain 303.

[0022] The transmission chain 303 is connected to the rocker arm 305 and the film receiving disk 306 through chain shaft transmission, and the rocker arm 305 is arranged between the transmission chain 303 and the film receiving disk 306.

[0023] The rocker arm 305 is provided with a roller with wide sides and thin middle at one end, and a semicircular handle at the other side. The upper end of the outer surface of the semicircular handle is provided with a reaction bar of the micro switch 304 in contact with the semicircular handle; the lower end of the roller passes through the waste film.

[0024] The micro switch 304 is fixedly mounted on the outer cover of the transmission chain 303 and is located at the upper end of the rocker arm 305 .

[0025] A servo motor is provided in the conveying platform 1 , and the surface of the conveying platform 1 is a belt driven by the servo motor.

[0026] When the film sealing mechanism 2 continues to seal the edges, residual film is generated. Excessive residual film will loosen, causing the rocker arm 305 to sag. When the rocker arm 305 sags, the micro switch 304 is triggered, and the drive motor 302 rotates, thereby driving the film collection tray 306 to collect the film. When the film collection tray 306 collects the film, the residual film generates a pulling force to lift the rocker arm 305. When it is lifted to a certain height, the micro switch 304 is deactivated, the drive motor 302 stops rotating, and the film collection tray 306 stops collecting the film.

[0027] The specific implementation is as follows:

[0028] After the machine is turned on, the conveyor platform 1 operates, delivering the product to the film sealing mechanism 2. At this point, the film sealing mechanism 2 seals the upper and lower films, forming residual film. If excess film is generated, it will loosen, causing the rocker arm 305, which is in contact with the residual film, to sag. When the rocker arm 305 sags, the microswitch 304 is triggered, and the drive motor 302 rotates, thereby driving the film collection tray 306 to collect the film. As the film collection tray 306 collects the film, the residual film generates a pulling force that lifts the rocker arm 305. When it is lifted to a certain height, the microswitch 304 is deactivated, the drive motor 302 stops rotating, and the film collection tray 306 stops collecting the film. By using the connecting plate 5 to fix the film sealing mechanism 2 and the waste film recovery mechanism 3, and arranging the drive motor 302, the micro switch 304 and the rocker arm 305 in the waste film recovery mechanism 3, and utilizing the functional relationship between the rocker arm 305 and the waste film and the cooperation between the rocker arm 305 and the micro switch 304, the operation and stopping mode of the drive motor 302 is adjusted, thereby solving the problem mentioned in the background technology that "the current double-sided sealing waste film recovery mechanism 3 is fixed under the edge sealing mechanism. If the edge sealing mechanism will be adjusted in position as the product width changes, the adjusted edge sealing mechanism will be misaligned with the waste film recovery mechanism 3; in this way, the waste film needs at least two corner idler wheels to turn the waste film to the film collection tray 306, and finally it can be collected into the waste film tray. During this process, film jamming and film breakage will occur."

[0029] The above describes the present invention and its implementation methods. This description is not restrictive. What is shown in the accompanying drawings is only one of the implementation methods of the present invention. The actual structure is not limited to this. In short, if ordinary technicians in this field are inspired by it, without departing from the inventive purpose of the present invention, they can design structural methods and embodiments similar to the technical solution without creative design, which should all fall within the scope of protection of the present invention.
