[0001] This utility model relates to the technical field of nail packing equipment, and in particular to a nail feeding device. Background Technology

[0002] As a key consumable in fields such as construction and furniture manufacturing, the packaging efficiency of staples directly affects production costs and delivery cycles. In the packaging process, staples are typically fed through a hopper. Traditional hoppers use a single-stage baffle structure, resulting in a predictable falling trajectory and causing staple clusters to clump together and become difficult to break. The standard deviation of staple distribution within cartons is as high as 15%–20%, with a rate exceeding 8%, requiring manual secondary sorting. More seriously, clumped staples rub against each other during transport, causing staple head bending and a scrap rate exceeding 5%. Existing equipment is not compatible with multiple staple sizes; switching staple types requires readjusting the hopper height, resulting in poor adaptability. Utility Model Content

Detailed Implementation

[0018] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0019] See Figures 1-3 , Figure 1 This is a schematic diagram of the structure of a nail feeding device according to an embodiment of this application; Figure 2 This is a schematic diagram of the structure of the feeding component of a nail feeding device according to an embodiment of this application; Figure 3 This is a cross-sectional view of the feeding component of a staple feeding device according to an embodiment of this application. As shown in the figure, the device includes: a mounting frame 100 and a feeding component. The mounting frame 100 is disposed on the conveying path of the carton, and the feeding component is connected to the mounting frame 100. The feeding component includes: a first housing 200 with a feed inlet at its upper end, and an inclined first baffle 230 inside the first housing 200; a second housing 300 detachably connected to the first housing 200, and an inclined second baffle 310 inside the second housing 300, the lower end of the second housing 300 being connected to the carton; and a vertical drive unit 400 fixed to the mounting frame 100, connected to the first housing 200, and used to drive the first housing 200 and the second housing 300 to rise and fall. By setting a baffle plate inside the feeding assembly, the falling path of the staples is bent multiple times, forcibly separating the sticky staple clusters; by setting a vertical drive unit 400, the feeding assembly can dynamically adapt to the height of the carton, allowing the feeding assembly to move to the top edge of the carton, reducing dust pollution inside the carton; by setting a split first box 200 and a second box 300, it is easy to disassemble and maintain.

[0020] See Figure 3 Furthermore, in this embodiment, the first housing 200 includes a first cavity 210 and a second cavity 220 that are connected; the volume of the first cavity 210 is larger than that of the second cavity 220, and the connection between the first cavity 210 and the second cavity 220 is inclined to form a retaining ramp 240. The volume difference between the large and small cavities forms a natural buffer zone, allowing the nails to decelerate in the larger cavity and smoothly enter the smaller cavity, significantly reducing impact damage. The inclined retaining ramp 240 guides the nails to turn in an orderly manner, eliminating the problem of bent nails caused by disordered collisions and improving product consistency.

[0021] See Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of the structure of the first box 200 of a nail feeding device according to an embodiment of this application.

[0022] Furthermore, in this embodiment, the first baffle plate 230 is provided with two pieces. The first ends of the two baffle plates are connected to the middle of the feed inlet of the first cavity 210, and the second ends of the two baffle plates extend downward to above the baffle slope 240. By setting the two first baffle plates 230 as a structure with two-sided guides, the nail flow is evenly distributed, avoiding local congestion. The suspended design at the end of the baffle plate allows the nails to be pre-dispersed, laying the foundation for subsequent secondary distribution and reducing the risk of clumping from the source. During feeding, the nails are poured in from the feed inlet, dispersed once by the first baffle plate 230, dispersed again by falling into the baffle slope 240, and finally dispersed a third time by entering the second box 300 and being dispersed a third time by the second baffle plate 310.

[0023] Preferably, the first baffle plate 230 has connecting plates 231 on both sides, and the upper end of the connecting plates 231 has a hook; the upper middle part of the first cavity 210 has a bayonet, and the hook engages with the bayonet. By setting the connecting plates 231, the first baffle plate 230 can be disassembled and assembled without tools, allowing maintenance personnel to replace it by hand. The engagement of the hook and the bayonet ensures accurate resetting, eliminating the calibration process after traditional welding replacement and significantly reducing equipment downtime.

[0024] See Figure 3 Furthermore, in this embodiment, the lower end of the second cavity 220 is inserted into the second housing 300, and the outer side of the second cavity 220 is detachably connected to the second housing 300 via a snap fastener 500. The housing insertion and locking mechanism, combined with the rotating snap fastener 500, achieves a unified system of reliable sealing and rapid decoupling, improving maintenance efficiency; the deep insertion structure ensures connection stability under various operating conditions.

[0025] See Figure 2 Furthermore, in this embodiment, a detachable feed box 600 is connected to the upper end of the first cavity 210. The inner cavity of the feed box 600 gradually expands from one side near the first cavity 210 to the other side. The gradually expanding inlet softens the impact of the nail feed and protects the nail heads. The modular design supports quick replacement, and no adjustment of the main structure is required when adapting to different nail types, significantly improving the flexibility of the production line.

[0026] See Figure 3 Furthermore, in this embodiment, the inclination directions of the first baffle plate 230, the second baffle plate 310, and the baffle ramp 240 are different. The combination of different inclination angles forces the nails to follow a multi-directional zigzag path, continuously breaking the nail clusters together through direction changes.

[0027] See Figure 1 Furthermore, in this embodiment, two sets of vertical drive units 400 are provided, and the two sets of vertical drive units 400 are symmetrically arranged on both sides of the mounting frame 100. The dual-drive force symmetrical layout automatically cancels the off-center load torque, ensuring that the box body rises and falls smoothly without tilting.

[0028] See Figure 1 Furthermore, in this embodiment, the vertical drive unit 400 includes: a guide post 410, vertically disposed on the mounting frame 100; a sliding plate 420, sleeved on the guide post 410, the sliding plate 420 being connected to the first housing 200; and a drive cylinder 430, fixed to the sliding plate, the power output end of the drive cylinder 430 being connected to the mounting frame 100. By fixing the drive cylinder 430 to the sliding plate 420, the driving force is always ensured to be collinear with the direction of the slide plate's movement, completely avoiding the risk of off-center loading.

[0029] Furthermore, in this embodiment, the surfaces of the first baffle plate 230, the second baffle plate 310, and the baffle inclined surface 240 are provided with a wear-resistant ceramic layer. The ceramic layer gives the baffle surface extremely strong wear resistance and an extremely smooth surface, almost eliminating the adhesion of the pins. The surface corrosion resistance is suitable for harsh working conditions, and it requires no maintenance for life, reducing overall costs.

[0030] Furthermore, in this embodiment, the lower end of the second box 300 is connected to the carton on the conveyor belt, and the side of the second box 300 is provided with a magnetic suction array device for material discharge.

[0031] As can be seen from the above, the staple feeding device of this utility model causes the staple falling path to bend multiple times by setting a baffle plate in the feeding component, thus forcibly separating the sticky staple clusters; by setting a vertical drive unit, the feeding component can dynamically adapt to the height of the carton, so that the feeding component moves to the upper edge of the carton, reducing dust pollution inside the carton; by setting a split first box and a second box, it is easy to disassemble and maintain.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
