DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0024] The following disclosure provides many different embodiments or examples for implementing different solutions of the present utility model.

[0025] Refer to Figures 1 to 3As shown in the figure, a wrapping paper output device includes a frame 1, a material placement module 2, a tensioning module 3, and a discharging module 4. The material placement module 2 is used to place a material roll. After the wrapping paper is output from the material roll, it passes through the tensioning module 3 and the discharging module 4 in sequence. The discharging module 4 includes a discharging component 41, a cutting component 42, and a limiting component 43 arranged from bottom to top. The limiting component 43 includes two limiting plates 431 arranged horizontally at intervals. A gap adapted to the thickness of the wrapping paper is provided between the two limiting plates 431. The wrapping paper passes through the discharging component 41, the cutting component 42, and the gap from bottom to top in sequence.

[0026] A limiting component 43 is provided above the cutting component 42. The limiting component 43 constructs a gap. After the wrapping paper passes through the gap, the part between the discharging module 4 and the gap is in a vertical state or tends to be in a vertical state. At this time, the cutting component 42 can cut the wrapping paper smoothly and can easily cut off the wrapping paper.

[0027] In this embodiment, the limiting plates 431 extend along the width direction of the wrapping paper. The two limiting plates 431 are arranged at intervals along the thickness direction of the wrapping paper. A gap is formed between the two limiting plates 431. The distance between the two limiting plates 431 is adjustable so that the width of the gap can be changed to adapt to the thickness of the wrapping paper.

[0028] Specifically, the position of the limiting plate 431 can be adjusted through a waist-shaped hole, thereby changing the distance between the two limiting plates 431.

[0029] In this embodiment, the cutting component 42 includes a cutter 421 fixed on the frame 1 and a driving roller 422 rotatably arranged on the frame 1. At least one pressing piece 423 is fixed on the outer wall of the driving roller 422. The rotation axes of the pressing piece 423, the cutter 421, and the driving roller 422 are all parallel to the width direction of the wrapping paper. The driving roller 422 rotates under the drive of a first motor 424 to press the wrapping paper onto the cutter 421 for cutting. The driving roller 422 rotates periodically to control the output length of the wrapping paper.

[0030] In this embodiment, the discharging component 41 includes a driving roller 411 and a driven roller 412 arranged at intervals along the thickness direction of the wrapping paper. The driving roller 411 and the driven roller 412 are in transmission cooperation. The driving roller 411 rotates under the drive of a second motor 413. The wrapping paper passes between the driving roller 411 and the driven roller 412. Relying on the pushing of the driving roller 411 and the driven roller 412, the wrapping paper can move upward.

[0031] Specifically, a driving gear is provided on the driving roller 411, and a driven gear is provided on the driven roller 412. The driving gear and the driven gear are meshed. Therefore, when the driving roller 411 rotates, it will drive the driven roller 412 to rotate.

[0032] In this embodiment, at least one support roller 414 is provided below the driving roller 411. The wrapping paper output by the tensioning module 3 bypasses the support roller 414 and then enters between the driving roller 411 and the driven roller 412, thereby restricting the output position of the wrapping paper and ensuring that the wrapping paper passes through between the driving roller 411 and the driven roller 412.

[0033] In this embodiment, a swing arm 415 is rotatably provided on the frame 1, the driven roller 412 is provided on the swing arm 415, and the swing arm 415 can rotate under the drive of the driving member 416; when material discharging jams occur, the driving member 416 can be started to swing the driven roller 412 to move the driven roller 412 away from the driving roller 411, so that a relatively large gap appears between the driving roller 411 and the driven roller 412 to loosen the wrapping paper; the driving member 416 can be a cylinder.

[0034] In this embodiment, the tensioning module 3 includes a plurality of positioning rollers 31 and a plurality of follower rollers 32. The positioning rollers 31 are fixedly arranged on the frame 1 at intervals in the horizontal direction. A lifting plate 33 that can slide up and down is provided on the frame 1, and the follower rollers 32 are fixed on the lifting plate 33. The wrapping paper alternately bypasses the positioning rollers 31 and the follower rollers 32 and then enters the discharging module 4.

[0035] When the discharging module 4 pulls the wrapping paper, the follower rollers 32 will rise. When the discharging module 4 does not pull the wrapping paper, the follower rollers 32 will drop by gravity to pull out the wrapping paper on the material roll, thereby preventing the feeding speed from falling behind the pulling speed.

[0036] Specifically, guide columns are provided on the frame 1, and guide sleeves are provided on the lifting plate 33. The guide sleeves are slidably matched with the guide columns, so that the lifting plate 33 can freely slide up and down.

[0037] In this embodiment, two material supporting rollers 34 are fixedly arranged on the frame 1 at intervals. The tensioning module 3 is located between the two material supporting rollers 34. The wrapping paper bypasses one material supporting roller 34 and then is input into the tensioning module 3, and the wrapping paper output from the tensioning module 3 bypasses the other material supporting roller 34. The two material supporting rollers 34 mainly restrict the input position and the output position of the wrapping paper to facilitate the docking of the material placing module 2 and the discharging module 4.

[0038] In this embodiment, the material placing module 2 includes a material placing roller 21 and a third motor 22 for driving the material placing roller 21 to rotate. The material roll is mounted on the material placing roller 21, and the third motor 22 drives the material placing roller 21 to rotate, so as to let the material roll unwind.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
