Description

Technical Field

[0001] This utility model belongs to the field of arrow-piercing technology for packaging machines, specifically relating to the corner structure for arrow piercing. Background Technology

[0002] The arrow-shaped corner structure is a key guiding component in a strapping machine, primarily used to guide the strapping to smoothly turn at 90-degree corners. This structure is typically made of high-strength alloy or wear-resistant engineering plastics, and its internal design features precise, smooth, arc-shaped channels that effectively reduce frictional resistance of the strapping during sharp turns.

[0003] However, the corner structure of the baling machine in the current technology is usually made by integral casting, which makes the parts heavy and bulky, making it extremely inconvenient to operate in the narrow equipment installation space. In addition, the fixing bolt holes are designed on the inside of the structure, making it difficult to reach the installation tools. It is often necessary to disassemble and reassemble repeatedly to complete the tightening. The excessively large structure also occupies the valuable maintenance space inside the equipment. When replacing vulnerable parts or troubleshooting, it is necessary to disassemble the entire corner assembly first, which seriously affects the maintenance efficiency and has certain limitations. Utility Model Content

[0004] To address the technical problem that existing baling machines have an integrated arrow-piercing corner design, resulting in an excessively large structure that is extremely inconvenient to operate in confined installation spaces and makes maintenance difficult, this utility model provides an arrow-piercing corner structure.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] The arrow-piercing corner structure includes two symmetrically arranged aluminum frames; each aluminum frame has a straight module at its lower part at one end close to the other; each straight module has an arrow-piercing groove at one end close to the other; an arrow-piercing rod is installed in the arrow-piercing groove and connected to the straight module; a transmission groove is provided between the two arrow-piercing grooves, and the arrow-piercing grooves are connected to each other through the transmission groove; a belt inlet transition piece is provided at the upper part of one arrow-piercing groove; a belt inlet R-angle piece is provided above the belt inlet transition piece; a belt outlet transition piece is provided on the other arrow-piercing groove at the position corresponding to the belt inlet transition piece, and the height of the belt outlet transition piece is higher than the height of the belt inlet transition piece; a belt outlet R-angle piece is provided above the belt outlet transition piece at the position corresponding to the belt inlet R-angle piece.

[0007] Furthermore, each of the arrow slots is equipped with a guide wheel assembly at its bottom, which overlaps with the arrow rod inside the arrow slot.

[0008] Furthermore, the tape feed transition member has a first inclined groove at one end near the transmission groove; the tape output transition member has a second inclined groove at one end near the transmission groove.

[0009] Furthermore, the first inclined groove is wider at the top and narrower at the bottom; the second inclined groove is narrower at the top and wider at the bottom.

[0010] Furthermore, both the inlet and outlet R-corner pieces are triangular in shape, and the side closest to the transmission groove is curved.

[0011] Furthermore, a protrusion is provided on the lower part of the tape exit transition piece near the transmission groove; the arrow through groove below the tape exit transition piece is provided with a matching groove corresponding to the position of the protrusion.

[0012] Furthermore, the inclination angle of the second inclined groove is greater than that of the first inclined groove.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model facilitates the installation of the overall structure through modular design of the aluminum frame, infeed transition piece, guide wheel assembly, and outfeed R-corner piece. It is simple and quick to install, and the R-corner piece does not move. Only the arrow rod, infeed guide piece, and outfeed guide piece move. The space is relatively small, and the packing adaptability is stronger. It solves the technical problem that the existing packing machine is not integrated with the arrow corner, and the structure is too large, which makes it extremely inconvenient to operate in a narrow equipment installation space, resulting in difficulties in installation, maintenance and repair.

[0015] 2. In this utility model, the inlet and outlet R-corner pieces are both curved surfaces near the conveyor trough. Compared to a flat surface, the curved surface not only provides a smoother guiding path for the strapping, effectively reducing the frictional resistance of the strapping material during the conveying process and facilitating the output and conveying of the strapping, but also ensures that the strapping maintains an ideal bending angle when entering and exiting the conveyor trough, avoiding deformation or jamming of the strapping material caused by sharp turns, thus improving the overall working efficiency and reliability of the strapping machine.

[0016] 3. In this utility model, the inclination angle of the second inclined groove is greater than that of the first inclined groove. The packing strap passes through the conveyor groove from the first inclined groove and enters the second inclined groove. The larger inclination angle of the second inclined groove can provide stronger guiding force for the packing strap, ensuring that the strap material enters the next process quickly and accurately. In addition, the angle difference between the two inclined grooves forms a natural tension adjustment zone, which effectively avoids the slack or deviation of the packing strap during transmission, making the entire packing process smoother and more reliable.

[0017] 4. This utility model utilizes the structure of the first inclined groove, which is wider at the top and narrower at the bottom, to provide a larger margin of error when the packing strap enters, facilitating the initial centering and positioning of the strap. Furthermore, the design of the second inclined groove, which is wider at the bottom and narrower at the top, creates a natural guiding and expanding effect during the output stage of the packing strap, effectively preventing edge jamming of the strap during high-speed transmission. The gradual structure of the two inclined grooves works together to form an optimized transmission path from convergence to expansion, which not only significantly improves the smoothness of the packing strap's passage but also reduces frictional loss between the strap and the groove wall, increasing practicality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5As shown, the arrow-piercing corner structure includes two symmetrically arranged aluminum frames 1; a straight module 6 is provided at the lower part of the two aluminum frames 1 at their close ends; an arrow-piercing groove 5 is provided at the close ends of the two straight modules 6; an arrow-piercing rod is provided in the arrow-piercing groove 5, which is connected to the straight module 6, and the straight module 6 drives the arrow-piercing rod to move; a transmission groove 2 is provided between the two arrow-piercing grooves 5, and the arrow-piercing grooves 5 are connected to each other through the transmission groove 2, which is used to facilitate the transmission of packing straps; a guide wheel assembly 7 is provided at the bottom of each arrow-piercing groove 5, which overlaps with the arrow-piercing rod inside the arrow-piercing groove 5 to support the arrow-piercing rod.

[0027] One of the arrow slots 5 is provided with a strapping transition piece 4 at the top, which is rectangular in shape. The end of the strapping transition piece 4 near the transmission slot 2 is provided with a first oblique slot 11, which is wider at the top and narrower at the bottom, and is used to guide the strapping to move towards the transmission slot 2. A strapping R-corner piece 3 is provided above the strapping transition piece 4, which is triangular in shape and has an arc surface on the side near the transmission slot 2, to facilitate the movement of the strapping.

[0028] Another arrow-through groove 5 is provided with an exit transition piece 9 at the position corresponding to the inlet transition piece 4, and the height of the exit transition piece 9 is higher than the height of the inlet transition piece 4; a protrusion 13 is provided on the lower part of the exit transition piece 9 near the end of the transmission groove 2; a second inclined groove 12 is opened at the end of the exit transition piece 9 near the transmission groove 2, the upper part of the second inclined groove 12 is narrower and the lower part is wider, which is used to guide the packing tape away from the transmission groove; the inclination angle of the second inclined groove 12 is greater than that of the first inclined groove 11; a matching groove 10 is opened in the arrow-through groove 5 at the position corresponding to the protrusion 13, which is used to increase the inclination angle of the second inclined groove 12 to facilitate the output of the packing tape.

[0029] Above the tape exit transition piece 9, corresponding to the position of the tape entry R-corner piece 3, there is a tape exit R-corner piece 8. The tape exit R-corner piece 8 has a triangular structure and the side near the conveyor groove is curved to facilitate the output of the packing tape.

[0030] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0031] In use, the packing strap enters through the inlet R-angle piece 3. At this time, the operator operates the linear module 6 to move the through rod in the through groove 5. The packing strap is guided onto the through rod by the inlet guide. Then, the through rod carries the packing strap through the inlet transition groove into the transmission groove 2. The packing strap is moved from the transmission groove 2 to one end of the outlet transition piece 9. The outlet guide then carries the packing strap onto the outlet transition piece 9. Finally, the packing strap enters the outlet R-angle piece 8 and is output from the outlet R-angle piece 8, completing the guiding work of the packing strap.

[0032] In this utility model, the aluminum frame 1, the infeed transition piece 4, the guide wheel assembly 7, and the outfeed R-corner piece 8 are all modularly installed, which is convenient, simple and quick to install. The R-corner piece does not move, and only the arrow rod, the infeed guide piece and the outfeed guide piece move. The space is relatively small, and the packing adaptability is stronger. It solves the technical problem that the existing packing machine is not integrated with the arrow corner and has an excessively large structure, which makes it extremely inconvenient to operate in a narrow equipment installation space, resulting in difficulties in installation, maintenance and repair.

[0033] Furthermore, in this utility model, the inlet R-corner piece 3 and the outlet R-corner piece 8 have curved surfaces on the side closest to the conveyor trough. Compared to a flat surface, the curved surface not only provides a smoother guiding path for the strapping, effectively reducing the frictional resistance of the strapping material during the conveying process and facilitating the output and conveying of the strapping, but also ensures that the strapping maintains an ideal bending angle when entering and exiting the conveyor trough, avoiding deformation or jamming of the strapping material caused by sharp turns, thus improving the overall working efficiency and reliability of the strapping machine.

[0034] Furthermore, the inclination angle of the second inclined groove 12 in this invention is greater than that of the first inclined groove 11. The packing strap passes through the conveyor groove from the first inclined groove 11 and enters the second inclined groove 12. The larger inclination angle of the second inclined groove 12 can provide stronger guiding force for the packing strap, ensuring that the strap material enters the next process quickly and accurately. In addition, the angle difference between the two inclined grooves forms a natural tension adjustment zone, which effectively avoids the slack or deviation of the packing strap during transmission, making the entire packing process smoother and more reliable.

[0035] Furthermore, this invention utilizes the structure of the first inclined groove 11, which is wider at the top and narrower at the bottom, to provide a larger margin of error when the packing strap enters, facilitating the initial alignment and positioning of the strap. The design of the second inclined groove 12, which is wider at the bottom and narrower at the top, creates a natural guiding expansion effect during the strap output stage, effectively preventing edge jamming of the strap during high-speed transmission. The gradual transitions of the two inclined grooves work together to form an optimized transmission path from convergence to expansion, significantly improving the smoothness of the strap passage and reducing frictional loss between the strap and the groove walls, thus increasing practicality.
