Description

Technical Field

[0001] The utility model relates to the technical field of film-coating packaging equipment, in particular to a pneumatic scissor device with toothed strap blades. Background Art

[0002] With the rapid development of packaging and logistics, more and more products are transported and circulated by packaging. During the transportation and turnover process, products need to be tied and fixed with the help of strapping tape. When strapping, the products are usually packaged with the help of automatic strapping machines, so the quality requirements for the strapping tape to be rolled into a reel are relatively high.

[0003] After the strapping tape is wound, it needs to be cut. The traditional way of cutting the strapping tape is to do it manually, but the labor cost is high and does not meet the requirements of modern automated production. Therefore, automatic strapping tape cutting mechanisms have gradually emerged. For example, the applicant previously applied for an authorization announcement number CN218988460U, and the authorization announcement date is May 9, 2023. The patent name is "A cutting mechanism for a strapping tape winder". The cutting mechanism includes a knife holder, a driving cylinder, a bottom plate, a knife holder mounting plate, a lever and a swing cylinder. When cutting the strapping tape, it is necessary to drive the knife holder to extend through a rodless cylinder, and the knife core is closed under the drive of the driving cylinder to cut the strapping tape. In this scheme, the cutting of the strapping tape requires the cooperation of two groups of cylinders, that is, the cooperation between the rodless cylinder and the driving cylinder, so the structure is relatively complex, which increases the manufacturing cost of the equipment. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of the utility model is to provide a pneumatic scissors device with toothed strap blades, so as to solve the problems of complex structure and increased cost caused by the need for cooperation between multiple cylinders when cutting the strapping tape in the existing strapping tape cutting device.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] The present application provides a pneumatic scissors device with teeth on a strapping blade, the pneumatic scissors device comprising a driving cylinder, an externally opening blade core and a single-board blade shell, the single-board blade shell being formed with a slide groove, a side surface of the single-board blade shell adjacent to the externally opening blade core being formed with a cutting surface for shearing in cooperation with the externally opening blade core, the externally opening blade core being slidably installed in the slide groove, the driving cylinder being fixedly connected to the externally opening blade core for driving the externally opening blade core to move back and forth horizontally.

[0007] Furthermore, a plurality of continuously arranged saw teeth are formed on the blade of the outer opening blade core.

[0008] Furthermore, a feeding space which gradually decreases along the feeding direction of the strapping tape is formed on the outer opening knife core.

[0009] Furthermore, the pneumatic scissors device also includes a base plate, and the single-plate blade housing is fixedly mounted on the base plate.

[0010] The beneficial effects of the utility model are:

[0011] 1. A slide groove is provided on the single-board blade shell, and a cut surface is provided on one side of the adjacent outer opening blade core, the outer opening blade core is slidably installed in the slide groove, when the driving cylinder drives the outer opening blade core to move linearly along the slide groove, the distance between the outer opening blade core and the cut surface on the single-board blade shell gradually decreases, and the two cooperate to cut the strapping tape, the whole cutting device has a simple structure, is easy to manufacture, and has a reduced cost;

[0012] 2. By adopting the saw-shaped outer opening knife core shape structure, when cutting the strapping tape, the outer opening knife core can better complete the cutting operation of the strapping tape and prevent the strapping tape from slipping during cutting.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] See attached Figure 1 To Attachment Figure 2 As shown, this embodiment provides a pneumatic scissors device 100 with toothed strap blades, which includes a driving cylinder 20, an externally open blade core 40, a single-plate blade housing 30 and a bottom plate 10.

[0021] The single-board blade shell 30 is fixedly mounted on the base plate 10, and a slide groove penetrating the front and rear end surfaces is formed at the center position of the single-board blade shell 30. The outer opening blade core 40 is installed in the slide groove, and the outer opening blade core 40 forms a sliding connection with the slide groove, that is, the outer opening blade core 40 can move back and forth horizontally relative to the slide groove.

[0022] Refer to the attached Figure 4 As shown, the outer opening knife core 40 has a plurality of continuously arranged tooth-like serrations 41 formed on its blade, and the plurality of serrations 41 extend from top to bottom along the blade of the outer opening knife core 40. The arrangement of the serrations 41 can improve the clamping force of the outer opening knife core 40 on the strapping tape during cutting, thereby preventing the strapping tape from slipping at the outer opening knife core 40 during the cutting process.

[0023] Continue to refer to the attached Figure 4 As shown, in order to facilitate the strapping tape to enter the feeding space 50 formed between the outer opening blade core 40 and the single plate blade shell 30, the feeding space 50 is formed into a space structure that gradually shrinks along the feeding direction of the strapping tape.

[0024] Refer to the attached Figure 1 and attached Figure 2 As shown, the outer side of the single-board blade shell 30 adjacent to the outer opening blade core 40 is formed with a cut surface 31 that cooperates with the outer opening blade core 40 for shearing. Figure 1 To Attachment Figure 3 As shown, the outer opening knife core 40 is fixedly connected to the driving cylinder 20. When the strapping tape is cut, (refer to the attached Figure 3 ) The driving cylinder 20 drives the outer opening knife core 40 to move closer to one side of the single board knife shell 30, that is, the distance between the outer opening knife core 40 and the cut surface 31 on the outer side of the single board knife shell 30 gradually decreases, and the outer opening knife core 40 cooperates with the cut surface 31 on the single board knife shell 30 to achieve the cutting of the packing tape.
