Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic production equipment of brushes, and more particularly to a nail taking device. BACKGROUND

[0002] In the field of modern industrial manufacturing, with the continuous improvement of automation level, the requirements for production efficiency and process precision are increasingly strict. Among the many assembly processes of brushes, the nail taking device is used to take nails out of the nail magazine in a specified order. After the brush head and handle are installed, the device automatically nails the nails into the connection between the brush head and handle, fixing the brush head and handle. The precise arrangement and efficient taking and placing of nails are one of the key links that affect the overall production efficiency. Currently, most small and medium-sized enterprises still use traditional manual nail taking methods, which not only have low efficiency (only 40-60 nails can be sorted per minute on average), but also have problems such as high labor intensity, high sorting error rate, etc. Even some enterprises that use automated equipment are generally faced with technical bottlenecks such as inaccurate nail taking device sorting, high nail jamming rate, and poor equipment compatibility. These problems seriously restrict the overall efficiency improvement of the production line and increase the operating costs of enterprises. Therefore, there is an urgent need for an automated device that can achieve high-speed, stable, and precise nail taking to meet the needs of modern intelligent manufacturing. SUMMARY

[0003] In view of the lack of automatic nail taking devices in the prior art, the present application provides a nail taking device that cooperates with a nail walking mechanism, a discharging mechanism, a nail arranging mechanism, and a nail dropping mechanism to achieve automatic nail taking and solve the deficiencies of the prior art.

[0004] To achieve the above-mentioned purpose, the technical scheme provided by the present application is as follows:

[0005] The present application provides a nail taking device, which comprises

[0006] a nail walking mechanism, the nail walking mechanism comprising a nail separating plate and a first nail walking groove formed on the nail separating plate, the first nail walking groove being used for arranging nails;

[0007] a discharging mechanism, the discharging mechanism being fixed on one end of the nail separating plate and having a nail magazine for accommodating a plurality of nails, the bottom of the nail magazine being provided with a magazine opening communicating with the first nail walking groove;

[0008] a nail arranging mechanism, the nail arranging mechanism being fixed on the nail separating plate and having a second nail walking groove, the second nail walking groove and the first nail walking groove being combined to form a nail walking channel for arranging the nails;

[0009] The nail falling mechanism is fixed on the end of the nail distribution plate away from the feeding mechanism, and is provided with a nail falling channel. The inlet of the nail falling channel is located at the lower end of the outlet of the nail walking channel, and receives the nails falling from the nail walking channel. The nails are forced to shoot out of the outlet of the nail falling channel.

[0010] In use, a plurality of nails are loaded into the nail magazine of the feeding mechanism. The nails enter the first nail walking groove from the magazine opening of the nail magazine mechanism, the nail shanks of the nails enter the first nail walking groove, and the nail heads of the nails are clamped on the surface of the first nail walking groove. The plurality of nails are arranged in the first nail walking groove in sequence. When the nail extractor is installed on the automatic equipment in an inclined state, the nails in the first nail walking groove can move along the first nail walking groove in sequence under the action of gravity. The second nail walking groove of the nail arranging mechanism covers the first nail walking groove to form a nail walking channel. The nails arranged on the first nail walking groove enter the nail walking channel in sequence, move in the nail walking channel, and are arranged in sequence. The nail walking channel can avoid the problem of nail clamping caused by the nails sliding out of the first nail walking groove or being stacked in front of and behind each other during movement. The nails enter the nail falling channel of the nail falling mechanism in sequence at the outlet of the nail walking channel, and each nail falls out of the outlet of the nail falling channel in sequence. The nail extractor can arrange the disordered nails in the magazine in sequence, and finally fall out of the nail falling channel in sequence. During this process, the nails are arranged in sequence, and the problem of nail clamping basically does not occur.

[0011] In the nail extractor provided in the present application, further, the first nail walking groove extends along a first direction and penetrates the end of the nail distribution plate. The width of the first nail walking groove is greater than the width of the nail shank and less than the width of the nail head.

[0012] The first nail walking groove extends along a first direction and penetrates the end of the nail distribution plate, which can effectively guide the nails to move in a predetermined direction, ensure the orderly arrangement and smooth conveying of the nails, and avoid nail clamping or misplacement. The width of the first nail walking groove is greater than the width of the nail shank and less than the width of the nail head, which can arrange the nail shanks downward and the nail heads upward, and ensure that the nails in the first nail walking groove are all oriented in the same direction.

[0013] In the nail extractor provided in the present application, further, a first viewing groove is formed in the nail distribution plate, which is formed on the side of the nail distribution plate away from the first nail walking groove and communicates with the first nail walking groove. The width of the first viewing groove is greater than the width of the first nail walking groove. Through the first viewing groove, the arrangement of the nails in the first nail walking groove can be clearly observed, and the specific position of the clamped nail can be determined. In addition, through the operation of the first viewing groove, the nail clamped at the position can be flexibly adjusted to ensure smooth and unobstructed movement of the nail. The width of the first viewing groove is greater than the width of the first nail walking groove, which can avoid the contact between the nail shank and the inner wall of the first viewing groove, and reduce the risk of nail clamping.

[0014] In the nail extractor provided in the application, further, the nail magazine comprises

[0015] A first baffle is fixed on one end of the nail separating plate away from the outlet of the nail channel;

[0016] An arc-shaped plate is fixed on one end above the first nail channel and is arranged opposite to the first baffle;

[0017] Side plates are connected on both sides of the first baffle and the arc-shaped plate respectively, and the first baffle and the arc-shaped plate are enclosed to form the nail magazine, and the bottom of the nail magazine is provided with the magazine opening communicating with the first nail channel;

[0018] A cover plate is connected on the top of the arc-shaped plate and the first baffle respectively to open and close the nail magazine.

[0019] The nail magazine forms a closed structure through the reasonable layout of the first baffle, the arc-shaped plate, the side plates and the cover plate, ensuring the stable storage and efficient conveying of nails. The openable and closable cover plate facilitates quick nail replenishment and maintenance; the precisely docked magazine opening enables the nails to automatically fall into the nail channel, improving the continuous operation efficiency. The compact overall structure has strong adaptability and can be applied to the automatic conveying of nails of different specifications, significantly improving the reliability and production efficiency of the nailing equipment, and is suitable for high-demand scenarios such as construction and packaging.

[0020] In the nail extractor provided in the application, further, the discharging mechanism comprises a nail pushing device arranged in the nail magazine, which has a rotating shaft and a nail pushing plate, and the rotating shaft is rotatably connected to the inner wall of the nail magazine at both ends; one end of the nail pushing plate is fixed on the rotating shaft and rotates with the rotating shaft to push the nails in the nail magazine. The function of the nail pushing plate is to disturb the nails in the nail box to prevent the squeezing phenomenon at the magazine opening, ensuring that the nails can smoothly pass through the magazine opening and enter the first nail channel, avoiding the occurrence of nail jamming.

[0021] In the nail extractor provided in the application, further, the nail pushing plate comprises a first blade and a second blade, one end of the first blade is fixed on the rotating shaft, and the second blade is detachably connected to the first blade.

By accurately controlling the movement trajectory of the nails, the working efficiency and reliability of the nail extractor can be further improved.

[0023] In the nail extractor provided in the application, further, the second nail groove has a width greater than the width of the nail cap of the nail and the width of the first nail groove. The second nail groove has a width greater than the width of the first nail groove, so that the nail groove forms a nail channel with a "T" shaped cross section. The nails entering the nail channel are completely limited, and the stacking phenomenon is avoided, thereby reducing the risk of jamming. Meanwhile, the second nail groove has a width greater than the width of the nail cap of the nail, so that the nail cap is smoothly clamped into the second nail groove, and the nail cap is limited and can only move along the extension direction of the nail channel.

[0024] In the nail extractor provided in the application, further, the nail feeding port of the nail channel is located in the nail magazine or communicates with the nail magazine. The nail feeding port of the nail channel is arranged in the nail magazine, so that the nails on the first nail groove in the range of the nail magazine can directly enter the nail feeding port. The nails that fail to fall into the first nail groove and are retained in the nail channel can be sent back to the nail magazine under the action of the nail pushing plate, so that the nails are recycled.

[0025] In the nail extractor provided in the application, further, a nail lifting surface is arranged on one side of the nail magazine, and the two ends of the nail lifting surface are smoothly connected to the surfaces of the nail separating plate and the nail feeding plate. The nail lifting surface is smoothly connected to the surfaces of the nail separating plate and the nail feeding plate, so that the step at the connection between the nail separating plate and the nail feeding plate (the nail feeding port of the nail channel) is eliminated. When the nail pushing plate pushes the nails, the nails accumulated at the connection between the nail separating plate and the nail feeding plate can be pushed away, so that the nails are not jammed due to the stacking and extrusion.

[0026] In the nail extractor provided in the application, further, a second viewing groove is formed on the nail feeding plate and communicates with the nail channel. The second viewing groove can observe the arrangement of the nails in the nail channel from one side of the nail feeding plate.

The second plate body is detachably connected to the nail distributing plate. When a nail is stuck in the second plate body, the nail can be removed by detaching the second plate body, without the need to completely detach the whole nail feeding plate, thereby saving the maintenance time.

[0028] In the nail extractor provided in the present application, further, the distance L between the end face of the outlet of the nail feeding channel and the end face of the nail distributing plate is 0.5-1.5 mm. When the distance L is greater than 1.5 mm, the nail is easy to jump out of the outlet of the nail feeding channel. When the distance L is less than 0.5 mm, the edge of the nail cap is easy to be stuck in the outlet of the nail feeding channel when the edge of the nail cap moves transversely to the nail falling channel, so that the nail cannot smoothly enter the nail falling channel.

[0029] In the nail extractor provided in the present application, further, the nail falling mechanism comprises

[0030] a base fixed to the nail distributing plate and located below the outlet of the nail feeding channel;

[0031] a side base connected to the base and forming a sliding channel and the nail falling channel between the base and the side base;

[0032] a nail pushing plate slidably connected in the sliding channel and provided with a nail pushing groove below the outlet of the nail feeding channel, the nail pushing groove receiving the nail dropped from the outlet of the nail feeding channel and moving the nail to the nail falling channel;

[0033] a jet device comprising an air compressor, the air outlet of the air compressor being communicated to the nail falling channel and injecting compressed gas into the nail falling channel for pushing the nail to move.

[0034] The nails dropped from the nail feeding channel in sequence are moved to the nail falling channel formed between the base and the side base by the nail pushing plate. The nail enters the pipe connected to the nail falling channel through the nail falling channel. The jet device pushes the nail in the nail falling channel or the pipe to the automatic nailing device connected to the other end of the pipe by injecting compressed air into the nail falling channel. The nail falling mechanism is used to ensure that the nail can be accurately and efficiently delivered to the target position, avoiding the jamming or blocking problem that may occur in the traditional way. Through the precise cooperation of the base and the side base, the design of the nail falling channel not only improves the stability of the overall structure, but also optimizes the flow path of the nail.

[0035] In the nail extractor provided in the application, further, the base comprises a positioning groove on the top thereof, which is clamped and fixed with a positioning block on the nail separating plate.

The cross-sectional opening size of the first guide surface decreases along the third direction, so that the first guide surface presents a horn mouth shape, facilitating the falling of the nail in the guide slot. The cross-sectional opening size of the second guide surface increases along the third direction, so that the nail falling from the first guide surface basically does not contact the inner wall of the second guide surface, avoiding the risk of nail jamming due to the scraping of the second guide surface. The nail falling from the second guide surface enters the third guide surface, the cross-sectional opening size of the third guide surface decreases along the third direction, and the nail in the third guide surface is righted by the third guide surface, so that the nail can fall in a state of the nail head up and the nail column down. The nail falling from the third guide surface enters the fourth guide surface, and the opening size of the fourth guide surface is constant, so that the falling state of the nail can be further corrected after the nail enters the fourth guide surface, and the nail can be kept in a vertical downward state to fall out of the nail falling channel.

[0093] In order to further understand the content of the present application, the present application will be described in detail in combination with the drawings and examples.

[0094] As Figure 1 shown, the present application provides a nail extractor, which comprises a nail walking mechanism 100, a feeding mechanism 200, a nail arranging mechanism 300 and a nail dropping mechanism 400. The nail walking mechanism 100 comprises a nail separating plate 110 and a first nail walking groove 120 opened on the nail separating plate 110, and the first nail walking groove 120 is used for arranging nails 600. The feeding mechanism 200 is fixed on one end of the nail separating plate 110, and has a nail magazine 210 for accommodating a plurality of nails 600, and the bottom of the nail magazine 210 is provided with a magazine opening 220 communicating with the first nail walking groove 120. The nail arranging mechanism 300 is fixed on the nail separating plate 110, and has a second nail walking groove 310 thereon, and the second nail walking groove 310 covers the first nail walking groove 120 to form a nail walking channel 320 for arranging the nails 600. The nail dropping mechanism 400 is fixed on the end of the nail separating plate 110 away from the feeding mechanism 200, and is provided with a nail dropping channel 410, and the inlet of the nail dropping channel 410 is located at the lower end of the outlet of the nail walking channel 320, and the nails 600 dropped from the nail walking channel 320 are received in the nail dropping channel 410, and the nails 600 are forced to be ejected from the outlet of the nail dropping channel 410.

[0095] 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.

[0096] Nail-walking mechanism 100:

[0097] like Figure 2 As shown, the nail-feeding mechanism 100 includes a first nail-feeding groove 120 and a nail-separating plate 110.

[0098] 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.

[0099] 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.

[0100] Feeding mechanism 200:

[0101] 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.

[0102] The staple cartridge 210 includes a first baffle 211. The first baffle 211 is fixed to the end of the staple distribution plate 110 opposite to the exit of the staple conveying channel 320. One end of the arc-shaped plate 212 is fixed above the first staple conveying groove 120 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.

[0103] The blanking mechanism 200 includes a nail poking device 230 arranged in the nail magazine 210, which has a rotating shaft 231 and a nail poking plate 232, and the two ends of the rotating shaft 231 are rotatably connected to the inner wall of the nail magazine 210. One end of the nail poking plate 232 is fixed on the rotating shaft 231, and the nail poking plate 232 rotates with the rotating shaft 231 and pokes the nails 600 in the nail magazine 210. The function of the nail poking plate 232 is to disturb the nails 600 in the nail box, prevent the squeezing phenomenon from occurring at the magazine opening 220, ensure that the nails 600 can smoothly pass through the magazine opening 220 and enter the first nail groove 120, and avoid the occurrence of the situation that the nails 600 are stuck. The nail poking plate 232 includes a first blade and a second blade. One end of the first blade is fixed on 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, which is generally made of plastic material, and the second blade can be easily replaced after being worn out.

[0104] The nail arranging mechanism 300 and the nail groove 320:

[0105] As shown in Figures 3-5 , the nail arranging mechanism 300 includes a nail entering plate 330. The nail entering plate 330 is provided with a second nail groove 310, and the second nail groove 310 and the first nail groove 120 are combined to form a nail groove 320. The nail groove 320 can avoid the nails 600 from separating from the first nail groove 120. The design of the nail groove 320 can also effectively reduce the shaking and deviation of the nails 600 during the conveying process, and ensure that each nail 600 moves stably along the predetermined path. By accurately controlling the motion trajectory of the nails 600, the working efficiency and reliability of the nail extractor can be further improved.

[0106] The width of the second nail groove 310 is greater than the width of the first nail groove 120 and the nail cap of the nail 600. The width of the second nail groove 310 is greater than the width of the first nail groove 120, which can form a nail groove 320 with a “T” shaped cross section. After the nail 600 enters the nail groove 320, it is completely limited and cannot be stacked, reducing the risk of being stuck. At the same time, the width of the second nail groove 310 is greater than the width of the nail cap of the nail 600, so that the nail cap can be smoothly clamped into the second nail groove 310, and the nail cap can only move along the extension direction of the nail groove 320.

[0107] The depth of the second nail groove 310 is between 1.1mm and 1.6mm. When the depth of the second nail groove 310 is less than 1.1mm, the nail cap and the nail part are easy to produce large friction with the bottom wall of the second nail groove 310, thereby causing the nail to be stuck. When the depth of the second nail groove is greater than 1.6mm, the nail caps of the front and rear nails 600 are easy to be stacked up and down, which is not conducive to the movement of the nails 600 in the nail groove 320, thereby causing the nails to be stuck.

[0108] The nail inlet of the nail channel 320 is located in the nail cartridge 210 or communicates with the nail cartridge 210. The nail inlet of the nail channel 320 is arranged inside the nail cartridge 210, which ensures that the nails 600 on the first nail channel 120 within the range of the nail cartridge 210 can directly pass through the nail inlet. As for those nails 600 that fail to fall into the first nail channel 120 and are stranded in the nail channel 320, they can be sent back to the nail cartridge 210 under the action of the nail pushing plate 232, thereby realizing the recycling of the nails 600.

[0109] The nail inlet plate 330 is provided with a nail lifting surface 331 on one side of the nail cartridge 210, and the two ends of the nail lifting surface 331 are smoothly connected to the surfaces of the nail separating plate 110 and the nail inlet plate 330, respectively. The nail lifting surface 331 smoothly connects the surface of the nail separating plate 110 and the surface of the nail inlet plate 330, eliminates the step at the connection between the nail separating plate 110 and the nail inlet plate 330 (the nail inlet of the nail channel 320), and enables the nail pushing plate 232 to push away the nails 600 accumulated at the connection between the nail separating plate 110 and the nail inlet plate 330 when pushing the nails, thereby avoiding the nail jamming caused by the stacking and extrusion of the nails 600.

[0110] The nail inlet plate 330 is provided with a second viewing groove 340 that communicates with the nail channel 320. The second viewing groove 340 can view the arrangement of the nails 600 in the nail channel 320 from one side of the nail inlet plate 330, directly find the jamming position of the nails 600 from the second viewing groove 340 when the nails 600 are jammed in the nail channel 320, and facilitate the pushing of the jammed nails 600 through the second viewing groove 340 to eliminate the jamming.

[0111] The nail inlet plate 330 includes a first plate body 332 and a second plate body 333. The first plate body 332 and the second plate body 333 are butted at one end and detachably connected to the nail separating plate 110 along the extension direction of the nail channel 320. The second plate body 333 is detachably connected to the nail separating plate 110. When the nails 600 are jammed in the second plate body 333, the second plate body 333 only needs to be detached to eliminate the jamming, without the need to completely remove the entire nail inlet plate 330, thereby saving maintenance time.

[0112] The distance L between the end portion of the nail inlet plate 330 at the outlet of the nail channel 320 and the end portion of the nail separating plate 110 is 0.5-1.5 mm. When the distance L is greater than 1.5 mm, the nails 600 are prone to jump out of the outlet of the nail channel 320. When the distance L is less than 0.5 mm, the edge of the nail cap of the nails 600 is prone to be jammed at the outlet of the nail channel 320 when moving transversely to the nail falling channel 410, so that the nails 600 cannot smoothly enter the nail falling channel 410.

[0113] As Figure 6As shown, a third cutout 112 is provided at the exit of the nail passage 320, the third cutout 112 extends in the opposite direction of the second direction 520 from the exit of the nail passage 320 and decreases in depth. The third cutout 112 can guide the nail 600 when it moves laterally, and can avoid the problem of nail jamming at the exit of the nail passage 320.

[0114] The nail falling mechanism 400:

[0115] As shown, Figures 7-8 The nail falling mechanism 400 includes a base 420, a side seat 430, a nail pushing plate 440, and a jet device 450.

[0116] The base 420 is fixed on the nail separating plate 110 and is located below the exit of the nail passage 320. The side seat 430 is connected to the base 420, and a slide 470 and a nail falling passage 410 are formed between the base 420 and the side seat 430. The nail pushing plate 440 is slidingly connected in the slide 470, and a nail pushing groove 441 is provided on the nail pushing plate 440, the nail pushing groove 441 is located below the exit of the nail passage 320, the nail pushing groove 441 receives the nail 600 falling from the exit of the nail passage 320, and moves the nail 600 into the nail falling passage 410. The jet device 450 includes an air compressor, the air outlet of the air compressor is connected to the nail falling passage 410, and compressed gas is injected into the nail falling passage 410 to push the nail 600 to move.

[0117] The nails 600 falling in the nail passage 320 in turn are moved laterally by the nail pushing plate 440 to the nail falling passage 410 formed between the base 420 and the side seat 430. The nail 600 enters a pipe connected to the nail falling passage 410 through the nail falling passage 410. The jet device 450 pushes the nail 600 in the nail falling passage 410 or the pipe to the automatic nailing device connected to the other end of the pipe by injecting compressed air into the nail falling passage 410. The nail falling mechanism 400 is used to ensure that the nail 600 can be accurately and efficiently delivered to the target position, avoiding the problem of jamming or blocking that may occur in the traditional way. Through the precise cooperation of the base 420 and the side seat 430, the design of the nail falling passage 410 not only improves the stability of the overall structure, but also optimizes the flow path of the nail 600.

[0118] As shown, Figure 9 The base 420 includes a positioning groove 421 at the top thereof. The positioning groove 421 is clamped and fixed with the positioning block 111 located on the nail separating plate 110. The positioning groove 421 and the positioning block 111 can realize quick clamping and ensure the accuracy of clamping.

[0119] The base 420 comprises an elongated slot 422 opened on the top of the base 420, which is located directly below the first spike slot 120 and elongates the depth of the first spike slot 120. The elongated slot 422 elongates the depth of the first spike slot 120 at the base 420, so that the nail 600 with a longer nail column can also pass through the base 420 smoothly without being stuck at the base 420.

[0120] The base 420 comprises a sliding groove 423 in which the push nail plate 440 is slidably connected. The sliding groove 423 is part of the sliding channel 470. The sliding groove 423 is used to slidably connect the push nail plate 440, so that the push nail plate 440 can be smoothly slid in the sliding channel 470.

[0121] The base 420 is provided with a rounded corner guide 424 matched with the push nail plate 440, which protrudes from the connection between the push nail slot 441 and the base 420. The rounded corner guide 424 can protrude into the push nail slot 441, and when the nail 600 moves downward in the push nail slot 441, the rounded corner guide 424 can push the nail 600 to the center of the nail drop channel 410, thereby avoiding the connection gap between the push nail slot 441 and the base 420, and preventing the nail 600 from being stuck on the connection gap.

[0122] The nail drop channel 410:

[0123] As Figures 9-10As shown, the nail falling channel 410 includes a first half slot 411 opened on the base 420. The first half slot 411 has a first guide surface 4111, a second guide surface 4112, a third guide surface 4113 and a fourth guide surface 4114 connected in turn and smoothly transitioned in the 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 cap of the nail 600 and does not change. The cross-sectional opening size of the first guide surface 4111 decreases along the third direction 530, so that the first guide surface 4111 presents a horn mouth shape, facilitating the falling of the nail 600 in the guide slot. The cross-sectional opening size of the second guide surface 4112 increases along the third direction 530, so that the nail 600 falling from the first guide surface 4111 does not substantially contact the inner wall of the second guide surface 4112, avoiding the risk of nail jamming due to the second guide surface 4112 rubbing and tilting. The nail 600 falling from the second guide surface 4112 enters the third guide surface 4113, and the cross-sectional opening size of the third guide surface 4113 decreases along the third direction 530. The nail 600 in the third guide surface 4113 will be righted by the third guide surface 4113, so that the nail 600 can fall in a state with the nail cap on top and the nail shank on the bottom. The nail 600 falling from the third guide surface 4113 enters the fourth guide surface 4114, and the cross-sectional opening size of the fourth guide surface 4114 does not change, so that the falling state of the nail 600 can be further corrected after entering the fourth guide surface 4114, so that it can remain in a vertical downward state and fall out of the nail falling channel 410.

[0124] A first cutout 425 is opened on the top of the base 420 at the junction with the nail separating plate 110. The first cutout 425 is located directly above the first half slot 411 and has a decreasing depth along the third direction 530. The first cutout 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, avoiding the nail 600 from being stuck there.

[0125] The falling nail channel 410 includes a second half slot 412 opened on the side seat 430, and the second half slot 412 is arranged opposite to the first half slot 411, and the two are combined to form the falling nail channel 410. The second half slot 412 has a fifth guide surface 4121, a sixth guide surface 4122 and a seventh guide surface 4123 which are sequentially and smoothly connected in the third direction 530. The cross-sectional opening size of the fifth guide surface 4121 is the same, which is composed of a straight section 4124 and a semicircular section 4125. The cross-sectional opening size of the sixth guide surface 4122 decreases along the third direction 530. 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 nail groove 441. The fifth guide surface 4121 composed of the straight section 4124 and the semicircular section 4125 can increase the cross-sectional area of the fifth guide surface 4121, facilitate the transverse movement of the nail 600 in the push nail groove 441 and into the fifth guide surface 4121, and avoid jamming. The fifth guide surface 4121 falls out of the nail 600 into the sixth guide surface 4122. The cross-sectional opening size of the sixth guide surface 4122 decreases along the third direction 530, which can correct the falling direction of the nail 600 and keep it in a vertical falling state, thereby reducing the risk of nail column and cap scratching and jamming of the nail 600.

[0126] The push nail plate 440 and the push nail groove 441:

[0127] As shown in Figures 11-12 , the push nail plate 440 includes a push plate 442 and a sliding block 443, and the push plate 442 and the sliding block 443 are fixedly connected and present an "L" shape.

[0128] The push plate 442 is slidingly connected in the slide 470. The push plate 442 has a push nail groove 441 opened thereon along the third direction 530 (the thickness direction of the nail plate 110 or the extension direction of the falling nail channel 410). The push nail groove 441 reciprocates between the outlet of the nail walking channel 320 and the falling nail channel 410, and moves the nails 600 falling from the outlet of the nail walking channel 320 into the falling nail channel 410. The push nail groove 441 can reciprocate between the nail walking channel 320 and the falling nail channel 410, and transversely push the nails 600 falling from the nail walking channel 320 into the falling nail channel 410. The push nail groove 441 pushes only one nail 600 at a time, so that only one nail 600 enters the falling nail channel 410 at a time.

[0129] The push-nail groove 441 comprises a first groove section 4411, a second groove section 4412 and a third groove section 4413 connected in sequence and smoothly. The first groove section 4411 is located at the port of the push-nail groove 441. The second groove section 4412 has an opening size increasing along the third direction 530. The third groove section 4413 has an opening size increasing along the first direction 510. The first groove section 4411 is used for pushing the nail 600. The second groove section 4412 has an opening size increasing along the third direction 530, which can reduce the contact opportunity between the nail 600 and the side wall of the second groove section 4412. The third groove section 4413 has an opening size increasing along the first direction 510, which can increase the opening size and depth, further reduce the contact between the nail 600 and the side wall of the second groove section 4412, and cause the risk of nail clamping.

[0130] The push plate 442 comprises a side notch 4421. The side notch 4421 is arranged on the push plate 442 and faces one side of the nail separating plate 110. The notch extends from the edge of the push-nail groove 441 to the second direction 520 (the width direction of the nail separating plate 110). The side notch 4421 can avoid the nail column front end of the nail 600 from being clamped in the gap between the push plate 442 and the base 420 or the nail separating plate 110 during the pushing process of the push-nail groove 441, and reduce the risk of nail clamping. The notch size or depth of the side notch 4421 gradually decreases along the second direction 520. The notch size or depth of the side notch 4421 gradually decreases along the second direction 520, which can avoid the nail column from falling into the notch completely, and reduce the risk of nail clamping.

[0131] The push plate 442 is provided with a second notch 4422. The second notch 4422 is located at the port of the push-nail groove 441.

[0132] The push plate 442 is provided with a plurality of push nail auxiliary grooves 4423 on the side away from the nail separating plate 110 along the third direction 530, and the push nail auxiliary grooves 4423 are parallel to the push nail grooves 441. The depth of the push nail auxiliary grooves 4423 increases along the third direction 530, and the push nail auxiliary grooves 4423 and the push nail grooves 441 are alternately arranged, and the width of the center of adjacent push nail grooves 441 is the same as the width of the center of adjacent push nail auxiliary grooves 4423. When the push nail grooves 441 return to the position directly below the nail walking channel 320, the push nail auxiliary grooves 4423 are directly opposite the nail falling channel 410, and the push nail auxiliary grooves 4423 can form a circular channel with the upper half of the nail falling channel 410 through which the common nails 600 pass. When a nail 600 is stuck in the upper half of the nail falling channel 410, the push plate 442 will touch the stuck nail during the process of the push nail grooves 441 retreating to the position directly below the nail walking channel 320, so that the stuck nail can pass through the circular channel formed by the push nail auxiliary grooves 4423 and the upper half of the nail falling channel 410 and enter the lower half of the nail falling channel 410, thereby eliminating the problem of stuck nails.

[0133] The push plate 442 includes a horizontal cross section 4424 at the bottom thereof, and the horizontal cross section 4424 is inclined to the side of the nail separating plate 110.

In addition, the sliding block 443 can also play an auxiliary clamping role when the push plate 442 is processed, so that the push nail grooves 441 and the like on the push plate 442 are easier to process.

[0135] One end of the push nail plate 440 is connected to the output end of the air cylinder 444, and the air cylinder 444 drives the push nail plate 440 to reciprocate in the slide 470.

[0136] The height difference between the top surface of the pushing plate 440 and the upper surface of the separating plate 110 is 0.5-1 mm. When the height difference is less than 0.5 mm, the nail cap of the outermost nail 600 and the nail cap of the second-to-last nail 600 cannot be stacked vertically at the outlet of the nail channel 320, and when the outermost nail 600 is pushed horizontally by the nail slot, the nail cap of the outermost nail 600 collides with the nail cap of the second-to-last nail 600, causing the nails 600 in the entire nail channel 320 to vibrate in the opposite direction, which can easily cause the nails 600 in the entire nail channel 320 to be stacked and jammed. When the height difference is greater than 1 mm, the edge of the nail cap is easily suspended at the outlet of the nail channel 320, causing the nail to be jammed. When the height difference is 0.5-1 mm, the outermost nail 600 falls into the nail slot, the height of the nail cap of the outermost nail 600 is lowered, and the nail cap of the second-to-last nail 600 is pressed on the nail cap of the outermost nail 600. When the outermost nail 600 is pushed horizontally, the nail cap of the outermost nail 600 has a small contact area with the nail column of the second-to-last nail 600, which does not generate a reverse thrust on the second-to-last nail 600, and the problem of jamming of the nail channel 320 can be avoided.
