With the promotion of automatic packing technology, balers with automatic packing function are widely used, and the arrow baler is the most commonly used packing equipment.

[0003] The arrow guides on standard arrow threading and strapping machines are positioned by the shape of the components and the friction between the steel parts. This positioning mechanism can cause significant friction wear and deformation of the arrow shaft during use, making threading and strapping difficult and causing them to become stuck.

[0004] This case arose in response to the above-mentioned structural defects. Utility Model Content

[0022] The utility model provides an arrow shaft positioning mechanism of an arrow piercing baler, which is a group of components of the arrow piercing baler. The arrow piercing baler is as follows Figure 1 As shown, its structure mainly includes a gantry 3, a driving device 4, a lead device, and the arrow shaft 1 and arrow body guide body 2 of the utility model. The arrow body guide body 2 is arranged at one end of the bottom of the gantry 3, and the driving device 4 is used to send the arrow shaft 1 from the other end of the gantry 3 to the arrow body guide body 2. The structure of the sword-threading and baling machine is the existing technology and will not be repeated in this case. The technical point to be protected in this case is the structure of the specific arrow shaft positioning mechanism of the arrow shaft 1 and the arrow body guide body 2.

[0023] like Figure 2-4As shown, the arrow shaft positioning mechanism includes an arrow shaft 1 and an arrow shaft guide body 2. The arrow shaft guide body 2 includes a groove-shaped groove body 21. The bottom of the groove of the groove body 21 is provided with a sliding member 22 that slidably fits with the bottom surface of the arrow shaft 1. The sliding member 22 can be a bearing, or other components that achieve the same function, such as a pulley. The bearing is used to reduce friction between the bottom of the arrow shaft 1 and the arrow shaft guide body 2. Sliding members 23 are provided on both sides of the groove of the groove body 21, which slidably fit with the top surfaces of the arrow shaft 1 on both sides. The sliding member 23 is a cam follower, or other components that achieve the same function, such as a pulley. On the one hand, the cam follower is used to reduce the friction at the top of both sides of the arrow shaft 1; on the other hand, it has a guiding function. After the arrow shaft 1 has been used for a long time, the head of the arrow shaft 1 is at risk of bending upward. When the upward bent end of the arrow shaft 1 hits the cam follower, the cam follower can rotate and press the arrow shaft 1 downward, so that it enters the bottom of the cam follower, limiting the up and down freedom of the arrow shaft 1, achieving the effect of smooth strapping, and avoiding difficulties and jams in the strapping process.

[0024] The utility model provides bearings and cam followers at the bottom and sides of the slot body 21, and adopts rolling friction of the bearings and cam followers to replace traditional rigid collision friction, which can greatly reduce the friction loss of parts and the deformation of the arrow shaft 1, and extend the service life of the arrow shaft 1 and the smoothness during use.

[0025] like Figure 3 As shown, to prevent the arrow shaft 1 from hitting the entrance when entering the arrow body guide body 2, the two sides of the open end of the slot body 21 facing the arrow shaft 1 are outer octagonal guide slides 24. When the arrow shaft 1 deviates when entering the slot body 21, the guide slides 24 can assist the arrow shaft 1 to slide in.

[0026] like Figure 4 As shown, a layer of polymer wear-resistant material is covered in the groove of the groove body 21. By providing the polymer wear-resistant material 25 in the groove body 21, when the arrow shaft 1 contacts the inner wall of the groove body 21, the wear of the arrow shaft 1 can be reduced, and the arrow shaft 1 can be prevented from being deformed by impact.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
