Description

Technical Field

[0001] The utility model relates to the technical field of straw processing, in particular to a paper straw fixed-point cutting device. Background Art

[0002] Traditionally, beverage straws were primarily made of plastic. These materials are difficult to degrade after use and are often disposed of in landfills, causing significant environmental pollution. In recent years, the United Kingdom and other developed countries have introduced plastic bans to reduce plastic pollution. Subsequently, other developing and developed countries, such as India, South Africa, Thailand, and Costa Rica, have also implemented similar measures to restrict the use of plastic straws and promote the importance of paper straws. Customers' preference for environmentally friendly packaging will drive significant demand for paper straws. Paper straws are processed using cutting equipment.

[0003] For example, the Chinese patent application number CN202121705007.5 discloses an automatic paper straw tip cutting machine, which includes a first cutter disc and a second cutter disc. The second cutter disc is arranged directly above the first cutter disc, and a single bevel is provided on the outer side of the first cutter disc and the second cutter disc. The cutting machine cuts paper straws with the cutter discs. During cutting, the straws can be cut by rotating the first cutter disc clockwise and the second cutter disc counterclockwise. The surface of the cut paper straws is smooth and not deformed. However, due to the limited size of the cutter discs, during the cutting process, the two sets of cutter discs can often only cut a single set of straws. Therefore, in batch processing, low efficiency will occur, affecting mass production. Utility Model Content

[0004] In response to the above problems, the present invention proposes a fixed-point cutting device for paper straws to solve the problem that during the cutting process of existing cutting equipment, two sets of knife discs can often only cut a single set of straws, resulting in low efficiency in batch processing.

[0024] The straws that need to be cut are transported between the two sets of mounting plates 1 by the guide wheel for cutting, and the guide holes 3 on the positioning plate 2 limit the position of the straws.

[0025] Two movable rods 7 are placed up and down between the two sets of positioning plates 2. Multiple sets of cutting tools 8 are fixed on the outer side of the movable rods 7. The two adjacent cutting tools 8 are staggered. The two ends of the movable rods 7 pass through the two sets of mounting plates 1 respectively. The mounting plates 1 are slidably connected to the movable rods 7.

[0026] One of the mounting plates 1 is detachably connected to a mounting box B5 , and a power device for pushing the two movable rods 7 to move relative to each other is provided in the mounting box B5 .

[0027] The power device pushes the two movable rods 7 to move relative to each other, and the cutting edges of the two adjacent cutters 8 above and below are staggered to form a shear force, which quickly cuts the straws. When the movable rods 7 move, the cutters 8 can move synchronously. Therefore, the cutting equipment can cut multiple groups of straws at the same time, with high processing efficiency.

[0028] The detachable installation method of the installation box B5 facilitates maintenance of the power unit within the installation box B5 by the operator. Specifically, the installation box B5 includes a first assembly plate 51 and a first sheath 52. The first sheath 52 is mounted on one side of the first assembly plate 51, which is fixedly connected to the mounting plate 1. A bolt plate is fixedly provided on the side of the first sheath 52 near the mounting plate 1. A second fixing bolt 53 is threadedly connected to the bolt plate. The second fixing bolt 53 passes through the bolt plate and is threadedly connected to a threaded hole 11 on the outside of the mounting plate 1. When the installation box B5 is opened, the second fixing bolt 53 on the bolt plate is unscrewed from the threaded hole 11 on the outside of the mounting plate 1, and the first sheath 52 can be completely removed from the mounting plate 1 and the first assembly plate 51.

[0029] About the powerplant:

[0030] The power unit includes two sets of toothed plates 9, each fixedly connected to two movable rods 7. A gear 10 is disposed between the two sets of toothed plates 9. Gear 10 is rotatably connected to a first assembly plate 51, meshing with the toothed plates 9. A motor for controlling the rotation of gear 10 is disposed on the side of the first assembly plate 51 away from gear 10. The motor drives gear 10 to rotate, which meshes with the two sets of toothed plates 9 during rotation, driving the two sets of toothed plates 9 to move synchronously, one left and one right. The movable rod 7 fixed to the toothed plates 9 also drives the cutter 8 to move synchronously, achieving the desired straw cutting effect.

[0031] In a preferred solution, a mounting box A4 is detachably connected to another set of mounting plates 1 , and a guide device for limiting the horizontal movement of the movable rod 7 is provided in the mounting box A4 .

A bolt plate is fixedly mounted on the side of second sheath 42 adjacent to mounting plate 1. A third fixing bolt is threadedly connected to the bolt plate. The third fixing bolt passes through the bolt plate and is threadedly engaged with threaded hole 11 on the outside of mounting plate 1. Similarly, when mounting box A4 is opened, the third fixing bolt on the bolt plate is unscrewed from threaded hole 11 on the outside of mounting plate 1, and second sheath 42 can be completely removed from mounting plate 1 and second assembly plate 41.

[0033] Specifically, the guide device includes two polygonal prisms 44, a sliding sleeve 43 is provided on the outer side of the polygonal prism 44, the polygonal prism 44 is slidably connected to the sliding sleeve 43, the sliding sleeve 43 is fixedly connected to the second sheath 42, and the polygonal prism 44 is fixedly connected to the end of the movable rod 7 away from the installation box B5.

[0034] When the movable rod 7 is pulled by the power device and moves left and right, the polygonal prism 44 fixed to the movable rod 7 will slide along the inner wall of the sliding sleeve 43. The sliding sleeve 43 cooperates with the polygonal prism 44 to guide the polygonal prism 44, thereby improving the stability of the movable rod 7 during movement.

[0035] To facilitate maintenance of the cutting tool 8 on the movable rod 7, the positioning plate 2 is removably fixed between the two sets of mounting plates 1. In a preferred embodiment, the positioning plate 2 includes two sets of upper and lower facing sealing plates. The guide holes 3 are provided on the opposite sides of the two sets of positioning plates 2. A plurality of first fixing bolts 6 are threadedly connected at both ends of the sealing plates.

When removing the positioning plate 2 from the mounting plate 1, the first fixing bolts 6 at both ends of the sealing plates are unscrewed from the bolt holes on the outside of the mounting plate 1.

[0036] How this application works:

[0037] Straws to be cut are transported between two sets of mounting plates 1 by a guide wheel for cutting. Guide holes 3 on positioning plate 2 limit the straws' position. A power unit drives two movable rods 7 relative to each other, staggering the cutting edges of two adjacent cutters 8, creating a shearing force that quickly severs the straws. As the movable rods 7 move, the cutters 8 move synchronously, allowing the cutting machine to simultaneously cut multiple sets of straws, achieving high processing efficiency.
