Description

A packaging film winding and take-up device Technical Field

[0001] This utility model relates to the field of new material processing technology, and in particular to a packaging film winding and taking device. Background Technology

[0002] Packaging film is a thin film material used for packaging and protecting products. Commonly used films include PE film, suitable for protecting various surfaces such as wooden furniture, plastic packaging, electrical appliances, glass, and metal. PE protective film has excellent adhesion and water resistance. It plays a vital role in logistics and packaging, effectively protecting goods from drops, scratches, and moisture, and is widely used in electronics, food packaging, and many other fields.

[0003] Traditional packaging film production involves installing a drive source at the end of the winding roller during the take-up process. This installation structure causes the packaging film to be wrinkled because one end experiences a large torque while the other end experiences a small torque. To improve the above defects, this application discloses a packaging film winding and take-up device. Summary of the Invention

[0004] The purpose of this invention is to address existing problems by providing a packaging film winding and take-up device.

[0005] This utility model is achieved through the following technical solution: a packaging film winding and taking device, including a bed frame, upper guide rollers are arranged at intervals at one end of the bed frame, lower guide rollers are arranged below the upper guide rollers, a tensioning mechanism is arranged behind the upper guide rollers, a power roller is arranged at the other end of the bed frame, a driven wheel is connected to one end of the power roller, the driven wheel is connected to the driving wheel through a belt, the driving wheel is connected to the output shaft of a motor, a take-up roller is arranged behind the power roller, and the end shaft of the take-up roller is rotatably connected to the wall panel.

[0006] As a further improvement to the above solution, the number of upper guide rollers is not less than two, and they are installed at intervals above the bed frame;

[0007] Ensure that the packaging film has sufficient contact surface with the upper guide roller to enhance the friction between the surfaces of the packaging film and the upper guide roller.

[0008] As a further improvement to the above solution, the lower guide roller is installed below the bed frame and positioned directly below the two upper guide rollers;

[0009] Used to enhance the friction between the packaging film and the surface of the upper guide roller.

[0010] As a further improvement to the above solution, the tensioning mechanism includes a tensioning roller, the two ends of which are symmetrically connected to the outer ends of the support plate, the inner end of the support plate is connected to the outer side of the support plate, the end shaft is rotatably connected to the side plate, the side plate is provided with an arc-shaped groove, a pin is slidably arranged in the arc-shaped groove, and the inner end of the pin is connected to the support plate.

[0011] The tension roller is brought to its lowest position by its own weight, while the pin is at the bottom of the arc groove. Under the force of the displaced packaging film, the tension roller rotates through the end shaft, and at the same time the pin rotates with the support plate. The pin rotates in the arc groove, thereby tensioning the displaced packaging film.

[0012] As a further improvement to the above solution, a sliding groove is provided through the wall panel, and the sliding groove is inclined on the wall panel.

[0013] The inclined chute ensures that the take-up roller is always in contact with the drive roller, thus guaranteeing that the take-up roller rotates with the drive roller to wind up the packaging film.

[0014] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. It uses a motor-driven power roller to pull the packaging film wound on the guide roller. At the same time, under the action of gravity, the tension roller rotates in the arc groove under the guidance of the support plate and the pin shaft, and tensions the displaced packaging film. Driven by the power roller, the take-up roller rotates and winds the packaging film. In addition, the take-up roller moves away from the power roller as the packaged film is wound in the groove, which avoids wrinkles in the packaging film during the winding process.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] As shown in Figures 1 to 4, a packaging film winding and taking device includes a bed frame 1. Upper guide rollers 2 are spaced apart at one end of the bed frame 1, and lower guide rollers 3 are arranged below the upper guide rollers 2. A tensioning mechanism 4 is arranged behind the upper guide rollers 2. A power roller 5 is arranged at the other end of the bed frame 1. One end of the power roller 5 is connected to a driven wheel 6. The driven wheel 6 is connected to a driving wheel 8 through a belt 7. The driving wheel 8 is connected to the output shaft 9 of a motor. A take-up roller 10 is arranged behind the power roller 5. The end shaft 45 of the take-up roller 10 is rotatably connected to a wall panel 11. The wall panel 11 is mounted on the bed frame 1 through a corner bracket 13.

[0021] As a further improvement to the above solution, the number of upper guide rollers 2 is not less than two, and they are installed at intervals above the bed frame 1;

[0022] Ensure that the packaging film has sufficient contact surface with the upper guide roller 2 to enhance the friction between the surfaces of the packaging film and the upper guide roller 2.

[0023] As a further improvement to the above solution, the lower guide roller 3 is installed below the bed frame 1 and positioned directly below the two upper guide rollers 2;

[0024] This is used to enhance the friction between the packaging film and the surface of the upper guide roller 2.

[0025] As a further improvement to the above solution, the tensioning mechanism 4 includes a tensioning roller 41, the two ends of which are symmetrically connected to the outer ends of the support plate 42. The inner end of the support plate 42 is connected to the outer side of the end shaft 45, and the end shaft 45 is rotatably connected to the side plate 46. An arc-shaped groove 43 is provided on the side plate 46, and a pin 44 is slidably arranged in the arc-shaped groove 43. The inner end of the pin 44 is connected to the support plate 42.

[0026] The tension roller 41 is brought to its lowest position by its own weight, while the pin 44 is at the lowest end of the arc groove 43. Under the force of the displaced packaging film, the tension roller 41 rotates through the end shaft 45, and at the same time the pin 44 rotates with the support plate 42. The pin 44 rotates in the arc groove 43, thereby tensioning the displaced packaging film.

[0027] As a further improvement to the above solution, a sliding groove 12 is provided through the wall panel 11, and the sliding groove 12 is inclined on the wall panel 11;

[0028] The inclined chute 12 ensures that the take-up roller 10 is always in contact with the power roller 5, thus ensuring that the take-up roller 10 rotates with the power roller 5 to take up the packaging film.

[0029] The working principle of a packaging film winding and taking device is as follows: the power roller 5 driven by the motor pulls the packaging film wound on the guide roller. At the same time, the tension roller 41 rotates in the arc groove 43 under the action of gravity and the support plate 42 rotates in the direction of the pin shaft 44, thus tensioning the displaced packaging film. Driven by the power roller 5, the take-up roller 10 rotates and winds the packaging film. In addition, the take-up roller 10 moves away from the power roller 5 as the packaged film is wound and moves in the slide groove 12.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
