Description

Technical Field

[0001] This utility model relates to the field of automated brush production equipment technology, and more specifically, to a nail dropping mechanism for a nail remover. Background Technology

[0002] In modern industrial manufacturing, with the continuous improvement of automation levels, the requirements for production efficiency and process precision are becoming increasingly stringent. Among the many assembly processes for brushes, the nail picker removes nails from the nail magazine in a specified order. After the brush head and handle are installed, the equipment automatically drives the nails into the connection point, securing the brush head and handle. The precise arrangement and efficient handling of nails are crucial to overall production efficiency. Currently, most small and medium-sized enterprises still use traditional manual nail removal methods, which are not only inefficient (only 40-60 nails can be sorted per minute on average) but also suffer from high labor intensity and high sorting error rates. Even companies that have adopted automated equipment generally face technical bottlenecks such as inaccurate nail picking, high nail jamming rates, and poor equipment compatibility. These problems severely restrict the overall efficiency improvement of the production line and increase the operating costs of enterprises.

[0003] The nail-dropping mechanism of a nail extractor precisely removes the sequenced nails and transports them to the automated nailing equipment via a pipe connected to its outlet. If the nail-dropping mechanism cannot smoothly and accurately remove the nails from the sequence, it will severely impact production progress. Therefore, there is an urgent need for a nail-dropping mechanism that can achieve high-speed, stable, and precise nail removal to meet the demands of modern intelligent manufacturing. Summary of the Invention

[0004] To address the lack of a fast, stable, and precise nail-dropping mechanism in existing nail removers, this solution proposes a nail-dropping mechanism that utilizes a base, side seat, and nail-pushing plate in cooperation to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This application provides a nail-dropping mechanism for a nail remover, including...

[0007] The base is fixed to the nail plate;

[0008] Side seat, which is connected to the base, and a slide and a nail drop channel are formed between the side seat and the base;

[0009] A nail pusher plate is slidably connected within the slide rail and has a nail pusher groove located at the exit of the nail-carrying channel. The nail pusher groove receives nails falling from the exit of the nail-carrying channel and moves the nails into the nail-dropping channel.

[0010] During operation, nails falling sequentially from the nail-feeding channel are moved by a nail-pushing plate to the nail-dropping channel formed between the base and the side seat. The nail at the very front of the nail-feeding channel falls into a nail-pushing groove on the nail-pushing plate. As the nail-pushing plate moves, the groove carries the nail directly above the nail-dropping channel, where it slides down under gravity, completing the precise nail removal process. In this process, the nail-pushing plate can remove nails quickly, stably, and accurately, with fewer steps, reducing potential jamming or blockages. Through the precise fit between the base and the side seat, the nail-dropping channel design not only improves the overall structural stability but also optimizes the nail's flow path.

[0011] In the nail-dropping mechanism of the nail remover provided in this application, the base further includes a positioning groove at its top, which engages and is fixed with a positioning block located on the nail-dispensing plate. The positioning groove and the positioning block enable quick engagement while ensuring the accuracy of the engagement.

[0012] In the nail-dropping mechanism of the nail remover provided in this application, the base further includes an extension groove on its top, located directly below the first nail-carrying groove, extending the depth of the first nail-carrying groove. The extension groove increases the depth of the first nail-carrying groove at the base, allowing even longer nails to pass smoothly through the base without jamming.

[0013] In the nail-dropping mechanism of the nail remover provided in this application, the base further includes a groove for slidably connecting the nail-pushing plate. The groove is part of a slide track. The groove is used to slidably connect the nail-pushing plate, allowing the nail-pushing plate to slide smoothly and circulate within the slide track.

[0014] In the nail-dropping mechanism of the nail remover provided in this application, the base is further provided with a guide rounded corner adapted to the nail-pushing plate. The guide rounded corner protrudes from the connection between the nail-pushing groove and the base. The guide rounded corner can protrude into the nail-pushing groove. When the nail moves downward in the nail-pushing groove, the guide rounded corner can push the nail towards the center of the nail-dropping channel, thereby avoiding the connection seam between the nail-pushing groove and the base and preventing the nail from getting stuck in the connection seam.

[0015] In the nail dropping mechanism of a nail remover provided in this application, the nail dropping channel further includes a first half-groove formed on the base.

[0016] In the nail-dropping mechanism of the nail remover provided in this application, the first semi-groove has a first guide surface, a second guide surface, a third guide surface, and a fourth guide surface that are smoothly connected in sequence in the third direction. The cross-sectional opening size of the first guide surface decreases along the third direction, the cross-sectional opening size of the second guide surface increases along the third direction, the cross-sectional opening size of the third guide surface decreases along the third direction, and the cross-sectional opening size of the fourth guide surface is adapted to the size of the nail head and its opening size remains unchanged. The cross-sectional opening size of the first guide surface decreases along the third direction, making the first guide surface present a funnel shape, which facilitates the reception of nails falling from the guide groove. The cross-sectional opening size of the second guide surface increases along the third direction, so that after the nail falls from the first guide surface into the second guide surface, it will basically not contact the inner wall of the second guide surface, avoiding the risk of nail jamming due to scraping and tilting of the second guide surface. The nail falling from the second guide surface enters the third guide surface. The opening size of the third guide surface decreases along the third direction. Inside the third guide surface, the nail is straightened by the third guide surface, ensuring that the nail head is on top and the nail post is below when it falls. The nail falling from the third guide surface enters the fourth guide surface. The opening size of the fourth guide surface remains unchanged, allowing the nail to be further corrected after entering the fourth guide surface, ensuring that it falls vertically downwards out of the nail dropping channel.

[0017] In the nail-dropping mechanism of the nail remover provided in this application, a first cut is further provided at the junction of the top of the base and the nail-separating plate. The first cut is located directly above the first semi-groove, and its depth decreases along a third direction. The first cut is located at the junction of the base and the nail-separating plate, so that the nail can avoid the gap between the base and the nail-separating plate in the nail-pushing groove during the falling process, and prevent the nail from getting stuck at this point.

[0018] In the nail dropping mechanism of the nail remover provided in this application, the nail dropping channel further includes a second half-groove formed on the side seat, the second half-groove being disposed opposite to the first half-groove, and the two covering each other to form the nail dropping channel.

[0019] In a nail remover provided in this application, the second semi-groove further comprises a fifth guide surface, a sixth guide surface, and a seventh guide surface that are smoothly connected in a third direction. The fifth guide surface has a uniform cross-sectional opening size and is composed of a straight section and a semi-circular section. The cross-sectional opening size of the sixth guide surface decreases along the third direction, and the cross-sectional opening size of the seventh guide surface is uniform. The fifth and sixth guide surfaces face the nail pusher groove. The fifth guide surface, composed of a straight section and a semi-circular section, increases its cross-sectional area, facilitating the lateral movement of the nail within the nail pusher groove and its entry into the fifth guide surface without jamming. The nail falls from the fifth guide surface into the sixth guide surface. The sixth guide surface, with its cross-sectional opening size decreasing along the third direction, corrects the nail's falling direction, ensuring a vertical fall and reducing the risk of the nail post and head scraping and jamming.

[0020] In the nail-dropping mechanism of a nail remover provided in this application, the nail-pushing plate further includes a push plate slidably connected within the slide rail. The push plate has a nail-pushing groove formed along a third direction. The nail-pushing groove travels back and forth between the exit of the nail-moving channel and the nail-dropping channel, moving the nails falling from the exit of the nail-moving channel into the nail-dropping channel. The nail-pushing groove can circulate back and forth between the nail-moving channel and the nail-dropping channel, laterally pushing nails falling from the nail-moving channel into the nail-dropping channel. The nail-pushing groove pushes only one nail at a time, ensuring that only one nail enters the nail-dropping channel at a time.

[0021] In a nail remover provided in this application, the nail-pushing groove further comprises a first groove segment, a second groove segment, and a third groove segment that are smoothly connected in sequence. The first groove segment is located at the port of the nail-pushing groove; the opening size of the second groove segment increases along a third direction; and the opening size of the third groove segment increases along a first direction. The first groove segment is used to push the nail, and the increasing size of the second groove segment along a third direction reduces the chance of the nail contacting the sidewall of the second groove segment. The increasing size and depth of the opening of the third groove segment along the first direction further reduces the risk of the nail getting stuck due to contact with the sidewall of the second groove segment.

[0022] In a nail remover provided in this application, the push plate further includes a side cut, which is disposed on the side of the push plate facing the nail separator, and the cut extends from the edge of the nail pusher groove in a second direction. The side cut can prevent the front end of the nail from getting stuck in the gap between the push plate and the base or nail separator during the pushing process of the nail pusher groove, reducing the risk of nail jamming.

[0023] In the nail-dropping mechanism of the nail remover provided in this application, the size or depth of the side cut gradually decreases along the second direction. This gradual decrease in the size or depth of the side cut along the second direction prevents the nail from falling completely into the cut, reducing the risk of nail jamming.

[0024] In the nail-dropping mechanism of the nail remover provided in this application, a second slit is further provided on the push plate. The second slit is located at the end of the nail-dropping groove, and its depth decreases along the third direction, while its width decreases from both sides towards the middle. The decreasing depth of the second slit along the third direction prevents the nail head from hanging on the top surface of the push plate. The decreasing width of the second slit from both sides towards the middle prevents the nail head from hanging on the top surface of the side wall of the push plate, reducing the risk of nail jamming.

[0025] In the nail-dropping mechanism of a nail remover provided in this application, further, a nail-pushing auxiliary groove is formed on the side of the push plate away from the nail-separating plate along a third direction, and the nail-pushing auxiliary groove is arranged parallel to the nail-pushing slot. The depth of the nail-pushing auxiliary groove increases along the third direction, and there are multiple nail-pushing auxiliary grooves and nail-pushing slots, which are arranged alternately, and the width at the center of adjacent nail-pushing slots is the same as the width at the center of adjacent nail-pushing auxiliary grooves. When the nail-pushing slot returns to the nail-carrying channel, the nail-pushing auxiliary groove is directly opposite the nail-dropping channel, and the nail-pushing auxiliary groove can form a circular channel with the upper half of the nail-dropping channel for nails to pass through. When a nail is stuck in the upper half of the nail-dropping channel, during the process of the nail-pushing slot retracting to the nail-carrying channel, the push plate will touch the stuck nail, so that the stuck nail can enter the lower half of the nail-dropping channel through the circular channel formed by the nail-pushing auxiliary groove and the upper half of the nail-dropping channel, thus eliminating the nail-stuck problem.

[0026] In the nail-dropping mechanism of the nail remover provided in this application, the push plate further includes a cross-section at its bottom, which is inclined to one side of the nail-dispensing plate. The inclined surface can avoid the sixth guide surface in the nail-dropping channel, preventing the included angle with the sixth guide surface from being too small, thereby avoiding nail jamming problems.

[0027] In the nail-dropping mechanism of the nail remover provided in this application, the nail-pushing plate further includes a slider, which is fixedly connected to the bottom of the push plate and slidably connected within the slide rail, sliding with the push plate. The slider is connected to the push plate, increasing the contact area between the nail-pushing plate and the slide rail, ensuring stability during the sliding process. Furthermore, the slider also plays an auxiliary clamping role during push plate processing, making the nail-pushing grooves on the push plate easier to process.

[0028] In the nail-dropping mechanism of the nail remover provided in this application, one end of the nail-pushing plate is connected to the output end of a cylinder, and the cylinder drives the nail-pushing plate to reciprocate within the slide.

[0029] In the nail-dropping mechanism of the nail remover provided in this application, the height difference between the top surface of the nail-pushing plate and the upper surface of the nail-separating plate is 0.5mm to 1mm. When the height is less than 0.5mm, the nail heads of the outermost nail and the second-to-last nail at the exit of the nail-feeding channel cannot be stacked vertically. When the outermost nail is pushed laterally by the nail-catching groove, the outermost nail head and the second-to-last nail head collide with each other, causing the nails in the entire nail-feeding channel to vibrate in the opposite direction, easily resulting in nail jamming due to the superimposed force on the nails in the entire nail-feeding channel. When the height difference is greater than 1mm, the edge of the nail head is prone to hanging at the exit of the nail-feeding channel, resulting in nail jamming. When the height difference is in the range of 0.5mm to 1mm, the outermost nail falls into the nail-feeding groove, the height of the outermost nail head decreases, and then the nail head of the second-to-last nail presses on the nail head of the outermost nail. When the outermost nail is pushed laterally, the contact area between its head and the second-to-last nail post is small, so it will not generate a reverse thrust on the second-to-last nail, thus avoiding the problem of nails getting stuck in the nail path.

[0030] In the nail-dropping mechanism of the nail remover provided in this application, the nail-dropping mechanism further includes an air jet device. The air jet device has an air compressor and an air supply channel connected to the air compressor outlet. The air supply channel is located inside the base or side seat, and the air outlet of the air supply channel is located on the side wall of the nail-dropping channel. The air jet device can inject compressed gas into the nail-dropping channel through the air supply channel, providing thrust for the nails falling in the nail-dropping channel, so that the nails can smoothly reach the nail-driving equipment of the automated equipment. Compared with the air supply channel being located at the top of the nail-dropping channel, the air outlet of the air supply channel being located on the side wall of the nail-dropping channel can avoid turbulent compressed gas airflow, which could push the nails to move in the opposite direction within the nail-dropping channel and affect nail dropping.

[0031] In the nail-dropping mechanism of the nail remover provided in this application, the jetting device further includes an air distribution plate fixed to the base. The air distribution plate includes a main air passage and several branch air passages connecting to the main air passages. The main air passages are connected to the air compressor, and the several branch air passages are respectively connected to different air supply channels. The air distribution plate can evenly guide the compressed gas from the air compressor into each air drop channel and ensure the consistency of the compressed air injection time in each air drop channel.

[0032] In the nail-dropping mechanism of the nail remover provided in this application, the nail-dropping mechanism further includes a cover plate pressing on the side seat. The cover plate has a nail-stopping groove that surrounds the area between the outlet of the nail-carrying channel and the inlet of the nail-dropping channel. The nail-stopping groove on the cover plate, positioned between the outlet of the nail-carrying channel and the inlet of the nail-dropping channel, allows the nail to move within the nail-stopping groove when the nail-pushing plate pushes the nail, preventing the nail from detaching from the nail-pushing plate.

[0033] In the nail-dropping mechanism of a nail remover provided in this application, the nail-stopping groove further includes a circular groove and a vertical groove communicating with the circular groove. The circular groove surrounds the nail-dropping channel, and the vertical groove is located in the channel between the outlet of the nail-moving channel and the nail-dropping channel inlet. When the nail moves laterally, it can move along the vertical groove and enter the nail-dropping channel from the circular groove. A guide hook is connected to the circular groove near the nail-separating plate. The guide hook guides the nail as it enters the circular groove, causing it to move towards the center of the circular groove and enter the nail-dropping channel from the center, preventing the nail from getting stuck at the edge of the circular groove.

[0034] The beneficial effects of this application are:

[0035] This application provides a nail-dropping mechanism for a nail remover, including a base and a side seat, and a nail-dropping channel formed between them. Nails that fall out sequentially from the nail-moving channel are moved into the nail-dropping channel between the base and the side seat by a nail-pushing plate. The nail at the front of the nail-moving channel falls into a nail-pushing groove on the nail-pushing plate after exiting the channel. The nail-pushing groove moves with the nail-pushing plate, bringing the nail directly above the nail-dropping channel. The nail slides into the nail-dropping channel under gravity, completing the precise nail removal. In this process, the nail-pushing plate can remove nails quickly, stably, and accurately, with fewer removal steps, reducing potential jamming or blockage problems during nail removal. Through the precise cooperation between the base and the side seat, the design of the nail-dropping channel not only improves the stability of the overall structure but also optimizes the flow path of the nails.

[0066] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0067] like Figure 1As shown, this application provides a nail remover, including a nail feeding mechanism 100, a feeding mechanism 200, a nail arranging mechanism 300, and a nail dropping mechanism 400. The nail feeding mechanism 100 includes a nail-separating plate 110 and a first nail feeding groove 120 formed on the nail-separating plate 110, the first nail feeding groove 120 being used for arranging nails 600. The feeding mechanism 200 is fixed to one end of the nail-separating plate 110 and has a nail magazine 210 for accommodating a plurality of nails 600. The bottom of the nail magazine 210 has a magazine opening 220 communicating with the first nail feeding groove 120. The nail arranging mechanism 300 is fixed to the nail-separating plate 110 and has a second nail feeding groove 310 thereon. The second nail feeding groove 310 and the first nail feeding groove 120 cover each other to form a nail feeding channel 320 for arranging nails 600. The nail dropping mechanism 400 is fixed to one end of the nail-separating plate 110 away from the feeding mechanism 200. It is provided with a nail dropping channel 410. The nail inlet of the nail dropping channel 410 is located at the lower end of the exit of the nail-moving channel 320. It receives the nails 600 falling from the nail-moving channel 320. The nails 600 are ejected from the exit of the nail dropping channel 410 under the force.

[0068] During operation, several nails 600 are loaded into the nail magazine 210 of the feeding mechanism 200. The nails 600 enter the first nail-feeding groove 120 through the magazine opening 220 of the nail magazine 210, with the nail post of the nail 600 entering the groove and the nail head of the nail 600 engaging on the surface of the groove. The several nails 600 are arranged sequentially in the first nail-feeding groove 120. When the nail picker is installed on automated equipment, it is placed at an angle, allowing the nails 600 to move sequentially along the first nail-feeding groove 120 under gravity. The second nail-feeding groove 310 of the nail-laying mechanism 300 closes with the first nail-feeding groove 120 to form a nail-feeding channel 320. The nails 600 arranged on the first nail-feeding groove 120 sequentially enter the nail-feeding channel 320, moving and arranging themselves within it. The nail feeding channel 320 prevents nails 600 from slipping out of the first nail feeding slot 120 or from stacking together during their movement, thus avoiding nail jamming. Nails 600 sequentially enter the nail dropping channel 410 of the nail dropping mechanism 400 at the exit of the nail feeding channel 320, and each nail 600 falls out sequentially from the exit of the nail dropping channel 410. The nail retriever can arrange the disordered nails 600 in the hopper in order, and finally they fall out sequentially from the nail dropping channel 410. During this process, the nails 600 are arranged sequentially, and nail jamming is virtually nonexistent.

[0069] Nail-walking mechanism 100:

[0070] like Figure 2 As shown, the nail-feeding mechanism 100 includes a first nail-feeding groove 120 and a nail-separating plate 110.

[0071] The first nail guide groove 120 extends along the first direction 510 (the length direction of the nail guide plate 110 or the extension direction of the nail guide channel 320) and penetrates the end of the nail guide plate 110. The width of the first nail guide groove 120 is greater than the width of the nail post of the nail 600 and less than the width of the nail head of the nail 600. The first nail guide groove 120, extending along the first direction 510 and penetrating the end of the nail guide plate 110, can effectively guide the nail 600 to move in a predetermined direction, ensuring that the nails 600 are arranged in an orderly manner and transported smoothly, avoiding nail jamming or misalignment. The width of the first nail guide groove 120, greater than the width of the nail post of the nail 600 and less than the width of the nail head of the nail 600, allows the nails 600 to be arranged with the nail post facing down and the nail head facing up, ensuring that the nails 600 within the first nail guide groove 120 all face the same direction.

[0072] A first viewing groove 130 is provided on the nail-separating plate 110. The first viewing groove 130 is located on the side of the nail-separating plate 110 opposite to the first nail-guiding groove 120 and communicates with the first nail-guiding groove 120. The width of the first viewing groove 130 is greater than the width of the first nail-guiding groove 120. Through the first viewing groove 130, the arrangement of the nails 600 in the first nail-guiding groove 120 can be clearly observed, and the specific position of the stuck nails can be determined. In addition, by operating the first viewing groove 130, the position of the stuck nails 600 can be flexibly adjusted to ensure that the nails 600 move smoothly without obstruction. The fact that the width of the first viewing groove 130 is greater than the width of the first nail-guiding groove 120 can prevent the nail post from contacting the inner wall of the first viewing groove 130, reducing the risk of the nails 600 getting stuck.

[0073] Feeding mechanism 200:

[0074] like Figure 4 As shown, the feeding mechanism 200 includes a first baffle 211, an arc plate 212, a side plate 213, and a top plate 214. The first baffle 211, the arc plate 212, the side plate 213, and the top plate 214 together form a nail chamber 210.

[0075] The staple cartridge 210 includes a first baffle 211. The first baffle 211 is fixed to the end of the staple distribution plate 110 facing away from the exit of the staple conveying channel 320. One end of the arc-shaped plate 212 is fixed above the first staple conveying channel 320 and is positioned opposite to the first baffle 211. The two ends of the side plate 213 are respectively connected to the first baffle 211 and the arc-shaped plate 212, forming the staple cartridge 210 together with the first baffle 211 and the arc-shaped plate 212. The bottom of the staple cartridge 210 has a compartment opening 220 that communicates with the first staple conveying groove 120. The two ends of the top plate 214 are respectively connected to the top of the arc-shaped plate 212 and the first baffle 211, and are used to open and close the staple cartridge 210. The staple cartridge 210, through the reasonable layout of the first baffle 211, the arc-shaped plate 212, the side plate 213 and the top plate 214, forms a closed structure, ensuring the stable storage and efficient delivery of the staples 600. The openable top plate 214 facilitates quick nail replacement and maintenance; the precisely aligned slot 220 allows nails 600 to automatically fall into the nail feeding slot, improving continuous operation efficiency. The overall structure is compact and highly adaptable, suitable for automated feeding of nails 600 of different specifications, significantly improving the reliability and production efficiency of nailing equipment, and applicable to high-demand scenarios such as construction and packaging.

[0076] The feeding mechanism 200 includes a nail-pulling device 230 disposed within the nail magazine 210. This device has a rotating shaft 231 and a nail-pulling plate 232. Both ends of the rotating shaft 231 are rotatably connected to the inner wall of the nail magazine 210. One end of the nail-pulling plate 232 is fixed to the rotating shaft 231, rotating with the shaft and agitating the nails 600 within the nail magazine 210. The function of the nail-pulling plate 232 is to agitate the nails 600 within the nail magazine, preventing squeezing at the magazine opening 220 and ensuring that the nails 600 can smoothly pass through the magazine opening 220 and enter the first nail guide groove 120, avoiding nail jamming. The nail-pulling plate 232 includes a first blade and a second blade. One end of the first blade is fixed to the rotating shaft 231, and the second blade is detachably connected to the first blade. The second blade is used to scrape the nails 600 and is generally made of plastic material; it can be easily replaced after wear.

[0077] Nail mounting mechanism 300 and nail-carrying channel 320:

[0078] like Figure 3-5 As shown, the nail-laying mechanism 300 includes a nail-feeding plate 330. A second nail-feeding groove 310 is formed on the nail-feeding plate 330, which closes with the first nail-feeding groove 120 to form a nail-feeding channel 320. The nail-feeding channel 320 prevents the nails 600 from detaching from the first nail-feeding groove 120. The design of the nail-feeding channel 320 also effectively reduces the shaking and deviation of the nails 600 during the conveying process, ensuring that each nail 600 moves stably along a predetermined path. By precisely controlling the movement trajectory of the nails 600, the working efficiency and reliability of the nail remover can be further improved.

[0079] The width of the second nail guide groove 310 is greater than that of the first nail guide groove 120 and the width of the nail head 600. This greater width creates a T-shaped nail guide channel 320, which completely restricts the movement of the nail 600 after it enters the channel, preventing stacking and reducing the risk of jamming. Simultaneously, the greater width of the second nail guide groove 310 allows the nail head to smoothly engage in the groove, restricting its movement to the direction of the nail guide channel 320.

[0080] The depth of the second nail guide groove 310 is between 1.1mm and 1.6mm. When the depth of the second nail guide groove 310 is less than 1.1mm, the nail head is prone to significant friction with the bottom wall of the second nail guide groove 310, thus causing the nail to get stuck. When the depth of the second nail guide groove is greater than 1.6mm, the nail heads of the front and rear nails 600 tend to overlap, which is not conducive to the movement of the nails 600 within the nail guide channel 320, thus causing the nail to get stuck.

[0081] The nail inlet of the nail-carrying channel 320 is located inside or connected to the nail magazine 210. The nail inlet of the nail-carrying channel 320 being located inside the nail magazine 210 ensures that nails 600 on the first nail-carrying channel 320 within the nail magazine 210 can directly enter through this inlet. Nails 600 that fail to fall into the first nail slot 120 and remain in the nail-carrying channel 320 can be returned to the nail magazine 210 by the nail-removing plate 232, thus achieving the recycling of the nails 600.

[0082] The nail feed plate 330 is located on one side of the nail magazine 210 and has a nail-lifting surface 331. The two ends of the nail-lifting surface 331 are smoothly connected to the surfaces of the nail divider plate 110 and the nail feed plate 330, respectively. The nail-lifting surface 331 smoothly connects the surfaces of the nail divider plate 110 and the nail feed plate 330, eliminating the step at the connection between the nail divider plate 110 and the nail feed plate 330 (the nail inlet of the nail channel 320), so that the nail-removing plate 232 can remove the nails 600 piled up at the connection between the nail divider plate 110 and the nail feed plate 330 when removing nails, avoiding the nail jamming phenomenon caused by the stacking and squeezing of nails 600.

[0083] The nail feed plate 330 is provided with a second viewing slot 340 that connects to the nail feeding channel 320. The second viewing slot 340 allows the arrangement of nails 600 in the nail feeding channel 320 to be viewed from one side of the nail feed plate 330. When a nail gets stuck in the nail feeding channel 320, the location of the stuck nail can be directly found through the second viewing slot 340, and the stuck nail 600 can be easily moved through the second viewing slot 340 to remove the stuck nail.

[0084] The nail feed plate 330 includes a first plate 332 and a second plate 333. The first plate 332 and the second plate 333 are joined at one end and detachably connected to the nail guide plate 110 along the nail feeding channel 320. The second plate 333 is detachably connected to the nail guide plate 110. When a nail 600 becomes stuck in the second plate 333, only the second plate 333 needs to be removed to eliminate the jamming, without needing to completely remove the entire nail feed plate 330, thus saving maintenance time.

[0085] The distance L between the end of the nail feed plate 330 at the exit of the nail feeding channel 320 and the end of the nail separating plate 110 is 0.5~1.5mm. When the end distance L is greater than 1.5mm, the nail 600 is likely to jump out from the exit of the nail feeding channel 320. When the end distance L is less than 0.5mm, when the edge of the nail head of the nail 600 moves laterally to the nail dropping channel 410, the edge of the nail head is likely to get stuck at the exit of the nail feeding channel 320, preventing the nail 600 from smoothly entering the nail dropping channel 410.

[0086] like Figure 6 As shown, a third cut 112 is provided at the exit of the nail-carrying channel 320. The third cut 112 extends from the exit of the nail-carrying channel 320 in the opposite direction to the second direction 520, and the depth decreases. The third cut 112 can guide the nail 600 when it moves laterally, and at the same time, it can prevent the nail from getting stuck at the exit of the nail-carrying channel 320.

[0087] 400-degree pin-down mechanism:

[0088] like Figure 7-8 As shown, the nail dropping mechanism 400 includes a base 420, a side seat 430, and a nail pusher plate 440.

[0089] Base 420, which is fixed on the nail plate 110;

[0090] Side seat 430, the side seat 430 is connected to the base 420, and a slide 470 and a nail drop channel 410 are formed between the side seat 430 and the base 420;

[0091] A nail pusher plate 440 is slidably connected within the slide rail 470 and has a nail pusher groove 441. The nail pusher groove 441 is located at the exit of the nail-carrying channel 320. The nail pusher groove 441 receives the nails 600 that fall from the exit of the nail-carrying channel 320 and moves the nails 600 into the nail-dropping channel 410.

[0092] During operation, nails 600 falling sequentially from the nail-feeding channel 320 are moved by the nail-pushing plate 440 to the nail-dropping channel 410 formed between the base 420 and the side seat 430. The nail 600 at the very front of the nail-feeding channel 320 falls into the nail-pushing groove 441 on the nail-pushing plate 440. As the nail-pushing plate 440 moves, the nail-pushing groove 441 carries the nail 600 directly above the nail-feeding channel 320, where it slides down into the nail-dropping channel 410 under gravity, completing the precise nail removal process. In this process, the nail-pushing plate 440 can remove nails quickly, stably, and accurately, with fewer removal steps, reducing potential jamming or blockages during nail removal. Through the precise cooperation between the base 420 and the side seat 430, the design of the nail-dropping channel 410 not only improves the overall structural stability but also optimizes the flow path of the nails 600.

[0093] Nails 600, falling sequentially from the nail-feeding channel 320, are laterally moved by the nail-pushing plate 440 into the nail-feeding channel 410 formed between the base 420 and the side seat 430. The nails 600 then enter a pipe connected to the nail-feeding channel 410. The air jet device 450 injects compressed air into the nail-feeding channel 410, pushing the nails 600 in the channel or pipe to the automated nail-driving equipment connected to the other end of the pipe. The nail-feeding mechanism 400 ensures that the nails 600 are delivered accurately and efficiently to the target position, avoiding jamming or clogging problems that may occur in traditional methods. Through the precise cooperation between the base 420 and the side seat 430, the design of the nail-feeding channel 410 not only improves the stability of the overall structure but also optimizes the flow path of the nails 600.

[0094] Base 420:

[0095] like Figure 9 As shown, the base 420 includes a positioning groove 421 located at its top. The positioning groove 421 is engaged and fixed with a positioning block 111 located on the nail plate 110. The positioning groove 421 and the positioning block 111 can achieve quick engagement while ensuring the accuracy of the engagement.

[0096] The base 420 includes an extension slot 422 located on its top, directly below the first nail guide slot 120, extending the depth of the first nail guide slot 120. The extension slot 422 extends the depth of the first nail guide slot 120 at the base 420, allowing even longer nails 600 to pass smoothly through the base 420 without jamming.

[0097] The base 420 includes a groove 423 for slidingly connecting the pusher plate 440. The groove 423 is part of the slide rail 470. The groove 423 is used to slidely connect the pusher plate 440, so that the pusher plate 440 can smoothly slide within the slide rail 470.

[0098] The base 420 is provided with a guide rounded corner 424 that is adapted to the pusher plate 440. The guide rounded corner 424 protrudes from the connection between the pusher groove 441 and the base 420. The guide rounded corner 424 can protrude into the pusher groove 441. When the nail 600 moves downward in the pusher groove 441, the guide rounded corner 424 can push the nail 600 towards the center of the nail drop channel 410, thereby avoiding the connection seam between the pusher groove 441 and the base 420 and preventing the nail 600 from getting stuck in the connection seam.

[0099] Nail drop channel 410:

[0100] like Figure 9-10 As shown, the nail-dropping channel 410 includes a first semi-groove 411 formed on the base 420. The first semi-groove 411 has a first guide surface 4111, a second guide surface 4112, a third guide surface 4113, and a fourth guide surface 4114 that are smoothly connected in sequence along a third direction 530. The cross-sectional opening size of the first guide surface 4111 decreases along the third direction 530, the cross-sectional opening size of the second guide surface 4112 increases along the third direction 530, the cross-sectional opening size of the third guide surface 4113 decreases along the third direction 530, and the cross-sectional opening size of the fourth guide surface 4114 is adapted to the size of the nail head of the nail 600, and its opening size remains unchanged. The decreasing cross-sectional opening size of the first guide surface 4111 along the third direction 530 makes the first guide surface 4111 present a trumpet shape, facilitating the reception of the nail 600 falling into the guide groove. The opening size of the second guide surface 4112 increases towards the third direction 530. After the nail 600 falls from the first guide surface 4111 into the second guide surface 4112, it will not come into contact with the inner wall of the second guide surface 4112, avoiding the risk of the nail 600 getting stuck due to scraping or tilting of the second guide surface 4112. The nail 600 falls from the second guide surface 4112 into the third guide surface 4113. The opening size of the third guide surface 4113 decreases towards the third direction 530. The nail 600 will be straightened by the third guide surface 4113, so that the nail 600 falls with the head on top and the nail post on the bottom. The nail 600 falling from the third guide surface 4113 enters the fourth guide surface 4114. The opening size of the fourth guide surface 4114 remains unchanged, so that after the nail 600 enters the fourth guide surface 4114, the falling state of the nail 600 can be further corrected, so that it can fall out of the nail drop channel 410 in a vertical downward state.

[0101] A first cut 425 is provided at the junction of the top of the base 420 and the nail-separating plate 110. The first cut 425 is located directly above the first half-groove 411, and its depth decreases along the third direction 530. The first cut 425 is located at the junction of the base 420 and the nail-separating plate 110, so that the nail 600 can avoid the gap between the base 420 and the nail-separating plate 110 in the nail-pushing groove 441 during the falling process, and prevent the nail 600 from getting stuck at this point.

[0102] The nail-dropping channel 410 includes a second semi-groove 412 formed on the side seat 430. The second semi-groove 412 is disposed opposite to the first semi-groove 411, and the two cover each other to form the nail-dropping channel 410. The second semi-groove 412 has a fifth guide surface 4121, a sixth guide surface 4122, and a seventh guide surface 4123 that are smoothly connected in sequence in the third direction 530. The fifth guide surface 4121 has the same cross-sectional opening size and is composed of a straight section 4124 and a semi-circular section 4125. The cross-sectional opening size of the sixth guide surface 4122 decreases along the third direction 530, and the cross-sectional opening size of the seventh guide surface 4123 is the same. The fifth guide surface 4121 and the sixth guide surface 4122 face the push-pin groove 441. The fifth guide surface 4121 is composed of a straight section 4124 and a semi-circular section 4125, which increases the cross-sectional area of ​​the fifth guide surface 4121, making it easier for the nail 600 to move laterally within the push-pin groove 441 and enter the fifth guide surface 4121 without getting stuck. After the nail 600 falls out of the fifth guide surface 4121, it enters the sixth guide surface 4122. The size of the cross-sectional opening of the sixth guide surface 4122 decreases along the third direction 530, which can correct the falling direction of the nail 600, keeping it in a vertical falling state, thereby reducing the risk of the nail post and nail head scraping and getting stuck.

[0103] Push nail plate 440 and push nail groove 441:

[0104] like Figure 11-12 As shown, the pusher plate 440 includes a pusher plate 442 and a slider 443, which are fixedly connected and form an "L" shape.

[0105] A push plate 442 is slidably connected within a slide rail 470. A nail-pushing groove 441 is formed on the push plate 442 along a third direction 530 (the thickness direction of the nail-spreading plate 110 or the extension direction of the nail-dropping channel 410). The nail-pushing groove 441 travels back and forth between the exit of the nail-walking channel 320 and the nail-dropping channel 410, moving the nails 600 that fall from the exit of the nail-walking channel 320 into the nail-dropping channel 410. The nail-pushing groove 441 can circulate back and forth between the nail-walking channel 320 and the nail-dropping channel 410, laterally pushing the nails 600 that fall from the nail-walking channel 320 into the nail-dropping channel 410. The nail-pushing groove 441 pushes only one nail 600 at a time, ensuring that only one nail 600 enters the nail-dropping channel 410 at a time.

[0106] The push-pin groove 441 includes a first groove segment 4411, a second groove segment 4412, and a third groove segment 4413 that are smoothly connected in sequence. The first groove segment 4411 is located at the port of the push-pin groove 441. The opening size of the second groove segment 4412 increases along a third direction 530. The opening size of the third groove segment 4413 increases along a first direction 510. The first groove segment 4411 is used to push the nail 600. The increasing size of the second groove segment 4412 along the third direction 530 reduces the chance of the nail 600 contacting the sidewall of the second groove segment 4412. The increasing size and depth of the opening of the third groove segment 4413 along the first direction 510 further reduces the risk of the nail 600 contacting the sidewall of the second groove segment 4412 and getting stuck.

[0107] The push plate 442 includes a side cut 4421. The side cut 4421 is located on the side of the push plate 442 facing the nail-separating plate 110, and its cut extends from the edge of the push-nail groove 441 towards the second direction 520 (the width direction of the nail-separating plate 110). The side cut 4421 prevents the front end of the nail 600 from getting stuck in the gap between the push plate 442 and the base 420 or the nail-separating plate 110 during the pushing process of the nail 600 in the push-nail groove 441, reducing the risk of nail jamming. The size or depth of the side cut 4421 gradually decreases along the second direction 520. This gradual decrease in the size or depth of the side cut 4421 along the second direction 520 prevents the nail from falling completely into the cut, further reducing the risk of nail jamming.

[0108] A second notch 4422 is provided on the push plate 442. The second notch 4422 is located at the end of the push pin groove 441. Its depth decreases along the third direction 530, and its width decreases from both sides towards the middle. The decreasing depth of the second notch 4422 along the third direction 530 prevents the nail head 600 from hanging on the top surface of the push plate 442. The decreasing width of the second notch 4422 from both sides towards the middle prevents the nail head 600 from hanging on the top surface of the side wall of the push plate 442, reducing the risk of nail jamming.

[0109] A pusher plate 442 has a pusher groove 4423 on the side opposite to the nail-separating plate 110 along the third direction 530. The pusher groove 4423 is arranged parallel to the pusher slot 441. The depth of the pusher groove 4423 increases along the third direction 530. There are multiple pusher grooves 4423 and pusher slots 441, which are arranged alternately. The width at the center of an adjacent pusher slot 441 is the same as the width at the center of an adjacent pusher groove 4423. When the pusher groove 441 returns to the area directly below the nail-carrying channel 320, the pusher groove 4423 faces the nail-dropping channel 410. The pusher groove 4423 and the upper part of the nail-dropping channel 410 can form a circular channel through which nails 600 can pass. When a nail 600 is stuck in the upper part of the nail-dropping channel 410, as the pusher groove 441 retracts to the area directly below the nail-carrying channel 320, the pusher plate 442 will touch the stuck nail, allowing the stuck nail to pass through the circular channel formed by the pusher groove 4423 and the upper part of the nail-dropping channel 410 and enter the lower part of the nail-dropping channel 410, thus eliminating the nail-stuck problem.

[0110] The push plate 442 includes a cross-section 4424 at its bottom, which is inclined toward the nail-separating plate 110. The inclined surface can avoid the sixth guide surface 4122 in the nail drop channel 410, and avoid the angle between it and the sixth guide surface 4122 being too small, thereby avoiding nail jamming.

[0111] The pusher plate 440 includes a slider 443, which is fixedly connected to the bottom of the pusher plate 442. The slider 443 is slidably connected within the slide rail 470 and slides with the pusher plate 442. The slider 443, connected to the pusher plate 442, increases the contact area between the pusher plate 440 and the slide rail 470, ensuring stability during the sliding process. Furthermore, during the machining of the pusher plate 442, the slider 443 also provides auxiliary clamping, making it easier to machine the pusher groove 441 and other features on the pusher plate 442.

[0112] One end of the pusher plate 440 is connected to the output end of the cylinder 444, and the cylinder 444 drives the pusher plate 440 to reciprocate within the slide rail 470.

[0113] The height difference between the top surface of the pusher plate 440 and the upper surface of the nail divider plate 110 is 0.5mm to 1mm. When the height difference is less than 0.5mm, the nail heads of the outermost nail 600 and the second-to-last nail 600 at the exit of the nail channel 320 cannot be stacked vertically. When the outermost nail 600 is pushed laterally by the nail-locking groove, the outermost nail head and the second-to-last nail head collide with each other, causing the nails 600 in the entire nail channel 320 to vibrate in the opposite direction, which can easily lead to nail jamming due to the superimposed force on the nails 600 in the entire nail channel 320. When the height difference is greater than 1mm, the edge of the nail head is prone to hanging at the exit of the nail channel 320, resulting in nail jamming. When the height difference is within the range of 0.5mm to 1mm, the outermost nail 600 falls into the nail guide groove, and the height of the outermost nail 600 head decreases. Consequently, the nail head of the second-to-last nail 600 presses onto the nail head of the outermost nail 600. When the outermost nail 600 is pushed laterally, the contact area between its nail head and the second-to-last nail 600 post is small, so it will not generate a reverse thrust on the second-to-last nail 600, thus avoiding the problem of nails getting stuck in the nail guide channel 320.

[0114] Jet unit 450:

[0115] like Figure 10 As shown, the jet device 450 includes an air supply channel 451 formed within the base 420 or the side seat 430, with the outlet of the air supply channel 451 located on the side wall of the nail dropping channel 410. The jet device 450 injects compressed gas into the nail dropping channel 410 through the air supply channel 451, providing thrust to the nails 600 falling within the channel, ensuring the nails 600 reach the automated nailing equipment smoothly. Compared to having the air supply channel 451 located at the top of the nail dropping channel 410, having its outlet on the side wall prevents turbulent compressed gas flow that could push the nails 600 backward within the channel, thus affecting nail dropping.

[0116] The jet device 450 includes an air distribution plate 453, which is fixed on the base 420. The air distribution plate 453 includes a main air passage 4511 and several branch air passages 4512 connecting to the main air passages 4511. The main air passages 4511 are connected to the air compressor, and the several branch air passages 4512 are respectively connected to different air supply channels 451. The air distribution plate 453 can evenly guide the compressed gas from the air compressor into each air supply channel and ensure the consistency of the compressed air injection time in each air supply channel.

[0117] Cover plate 460:

[0118] like Figure 14As shown, the nail dropping mechanism 400 includes a cover plate 460 that presses against the side seat 430. A nail-stopping groove 461 is provided on the cover plate 460, surrounding the area between the outlet of the nail-carrying channel 320 and the nail-dropping channel 410. The nail-stopping groove 461 on the cover plate 460 is positioned between the outlet of the nail-carrying channel 320 and the nail-dropping channel 410, ensuring that when the nail-pushing plate 440 pushes the nail 600, the nail 600 moves within the nail-stopping groove 461, preventing the nail 600 from detaching from the nail-pushing plate 440.

[0119] The nail-stopping groove 461 includes a circular groove 4611 and a vertical groove 4612 communicating with the circular groove 4611. The circular groove 4611 surrounds the nail-dropping channel 410, and the vertical groove 4612 is located in the channel between the outlet of the nail-carrying channel 320 and the nail-dropping channel 410 inlet. When the nail 600 moves laterally, it can move along the vertical groove 4612 and enter the nail-dropping channel 410 from the circular groove 4611. A guide hook 462 is connected to the side of the circular groove 4611 near the nail-separating plate 110. The guide hook 462 guides the nail 600 as it enters the circular groove 4611, causing the nail 600 to move towards the center of the circular groove 4611 and enter the nail-dropping channel 410 from the center of the circular groove 4611, thus preventing the nail 600 from getting stuck at the edge of the circular groove 4611.

[0120] The first direction 510 is the extension direction of the nail-carrying channel 320 (the length direction of the nail-separating plate 110). The second direction 520 is perpendicular to the nail-carrying channel 320 (the width direction of the nail-separating plate 110); the third direction 530 is the extension direction of the nail-dropping channel 410 (the thickness direction of the nail-separating plate 110).

[0121] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
