[0002] In the modern industrial manufacturing field, with the continuous improvement of automation level, the requirements of production efficiency and process precision are increasingly strict. In many assembly processes, the accurate arrangement and efficient taking and placing of nails are one of the key links affecting the overall production efficiency. At present, most small and medium-sized enterprises still adopt the traditional manual nail taking mode, which not only has low efficiency (only 40-60 nails can be sorted per minute on average), but also has problems such as high labor intensity, high sorting error rate and the like. Even some enterprises using automatic equipment also generally face technical bottlenecks such as inaccurate nail sorting of the nail taking device, high nail jamming rate, poor equipment compatibility and the like. These problems seriously restrict the overall efficiency improvement of the production line and increase the operating cost of the enterprise.

[0003] The main function of the nail falling channel is to receive the nails pushed by the nail pushing plate and smoothly guide them to the pipeline below, which is directly connected to the automatic nailing equipment. At present, it is an urgent problem to be solved to facilitate the processing of the nail falling channel and ensure that the nails smoothly enter the pipeline below without obstruction. SUMMARY

[0004] In view of the technical problem in the prior art that there is no nail taking device nail falling channel that is convenient to process and does not jam nails, the present scheme provides a nail taking device nail falling channel, which solves the problem of the prior art by cooperating the first half groove and the second half groove.

[0005] To achieve the above-mentioned purpose, the technical scheme provided by the utility model is as follows:

[0006] A nail taking device nail falling channel comprises

[0007] A first half groove is provided on the base and extends in a third direction.

[0008] A second half groove is provided on the side seat and extends in the third direction. The second half groove is arranged opposite to the first half groove, and the two form the nail falling channel by covering each other. In this application, the nail falling channel is divided into the first half groove and the second half groove, and the first half groove and the second half groove cover each other. The first half groove and the second half groove can be machined separately, making the machining of the nail falling channel more convenient. In addition, by machining the first half groove and the second half groove separately, the internal shape of the first half groove and the second half groove can be easily machined and adjusted, which can eliminate the nail jamming steps in the falling process of the nails or correct the posture of the nails in the falling process by using the nail falling channel, greatly reducing the risk of nail jamming.

[0009] In the falling nail passage of the nail extractor provided in the present application, further, the first half slot comprises a first guide surface, and the cross-sectional opening size of the first guide surface decreases along the third direction. 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 nail falling from the guide slot.

[0010] In the falling nail passage of the nail extractor provided in the present application, further, the first half slot comprises a second guide surface, and the cross-sectional opening size of the second guide surface increases along the third direction. The cross-sectional opening size of the second guide surface increases along the third direction, so that after the nail falling from the first guide surface enters the second guide surface, the nail basically does not contact the inner wall of the second guide surface, avoiding the risk of nail jamming due to the scraping and tilting of the second guide surface.

[0011] In the falling nail passage of the nail extractor provided in the present application, further, the first half slot comprises a third guide surface, and the cross-sectional opening size of the third guide surface decreases along the third direction. After 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, so that the nail passes through the third guide surface in the third guide surface, and the third guide surface rightens the nail, so that the nail can fall in the state of the nail head up and the nail column down.

[0012] In the falling nail passage of the nail extractor provided in the present application, further, the first half slot comprises a fourth guide surface, the cross-sectional opening size of the fourth guide surface is matched with the size of the nail head of the nail, and the opening size of the fourth guide surface is constant. After the nail falling from the third guide surface enters the fourth guide surface, the opening size of the fourth guide surface is constant, so that after the nail enters the fourth guide surface, the falling state of the nail can be further corrected, so that the nail can fall out of the falling nail passage in the state of vertical downward.

[0013] In the falling nail passage of the nail extractor provided in the present application, further, the first half slot has a first guide surface, a second guide surface, a third guide surface and a fourth guide surface which are sequentially and smoothly connected 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 of the nail and is constant. 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 in the first guide surface will not contact the inner wall of the second guide surface after entering the second guide surface, avoiding the risk of nail jamming due to the scraping of the second guide surface. The nail falling in 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 will be righted in the third guide surface, so that the nail can fall in the state of the nail head up and the nail column down. The nail falling in 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 entering the fourth guide surface, so that it can keep a vertical downward state to fall out of the falling nail passage.

[0014] In the falling nail passage of the nail extractor provided in the present application, further, the second half slot includes a fifth guide surface, and the cross-sectional opening size of the fifth guide surface is the same, which is composed of a straight section and a semicircular section. The fifth guide surface composed of a straight section and a semicircular section can increase the cross-sectional area of the fifth guide surface, facilitating the lateral movement of the nail in the pushing nail slot and entering the fifth guide surface, and avoiding jamming.

[0015] In the falling nail passage of the nail extractor provided in the present application, further, the second half slot includes a sixth guide surface, and the cross-sectional opening size of the sixth guide surface decreases along the third direction. The fifth guide surface falls out of the nail and enters the sixth guide surface, and the cross-sectional opening size of the sixth guide surface decreases along the third direction, which can correct the falling direction of the nail, so that it can keep a vertical falling state, thereby reducing the risk of nail column and nail head scraping and jamming.

[0016] In the falling nail passage of the nail extractor provided in the present application, further, the second half slot includes a seventh guide surface, and the cross-sectional opening size of the seventh guide surface is the same. The same cross-sectional opening size of the seventh guide surface can correct the inclined nail column during the falling process of the nail, avoid its falling out of the falling nail passage outlet in an excessively inclined state, and make the nail jam in the pipeline.

[0017] In the falling nail channel of the nail extractor provided in the present application, further, the second half slot has a fifth guide surface, a sixth guide surface and a seventh guide surface which are sequentially and smoothly connected in the third direction, the fifth guide surface has the same cross-sectional opening size and is composed of a straight section and a semicircular 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 the same. The fifth guide surface, the sixth guide surface and the seventh guide surface are sequentially and smoothly connected, which can reduce the risk of nail hanging in the falling nail channel, and in addition, the falling posture of the nail in the fifth guide surface, the sixth guide surface and the seventh guide surface is corrected, avoiding the risk of nail jam caused by excessive deflection of the nail.

[0018] The beneficial effects of the present application are:

[0019] The present application provides a falling nail channel of a nail extractor, which is divided into a first half slot and a second half slot, and the first half slot and the second half slot are overlapped. The first half slot and the second half slot can be machined respectively, making the machining of the falling nail channel more convenient. In addition, by machining the first half slot and the second half slot respectively, the internal shape of the first half slot and the second half slot is easy to process and adjust, which is convenient for eliminating the nail jamming step in the falling process of the nail or correcting the posture of the nail in the falling process by using the falling nail channel, greatly reducing the risk of nail jamming.

[0050] For further understanding of the present application, the present application will be described in detail with reference to the drawings and examples.

[0051] As 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.

[0052] 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.

[0053] Nail-walking mechanism 100:

[0054] like Figure 2 As shown, the nail-feeding mechanism 100 includes a first nail-feeding groove 120 and a nail-separating plate 110.

[0055] 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.

[0056] 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.

[0057] Feeding mechanism 200:

[0058] 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.

[0059] The nail bin 210 comprises a first baffle 211. The first baffle 211 is fixed on the end of the split nail plate 110 away from the outlet of the nail channel 320. An arc-shaped plate 212 is fixed on the upper side of the first nail channel 320 at one end and is arranged opposite to the first baffle 211. Side plates 213 are connected to the two sides of the first baffle 211 and the arc-shaped plate 212 respectively at two ends, and form the nail bin 210 together with the first baffle 211 and the arc-shaped plate 212. A bin opening 220 is formed at the bottom of the nail bin 210 and is connected to the first nail channel 120. A top plate 214 is connected to the top of the arc-shaped plate 212 and the first baffle 211 respectively at two ends, and is used to open and close the nail bin 210. The nail bin 210 forms a closed structure through the reasonable layout of the first baffle 211, the arc-shaped plate 212, the side plates 213 and the top plate 214, thereby ensuring the stable storage and efficient conveying of the nails 600. The openable and closable top plate 214 facilitates fast nail replenishment and maintenance. The precisely docked bin opening 220 enables the nails 600 to automatically fall into the nail channel, thereby improving the continuous operation efficiency. The overall structure is compact and has strong adaptability, and can be applied to the automatic conveying of nails 600 of different specifications, thereby significantly improving the reliability and production efficiency of the nailing equipment and being suitable for high-demand scenarios such as construction and packaging.

[0060] The blanking mechanism 200 comprises a nail poking device 230 arranged in the nail bin 210. The nail poking device 230 has a rotating shaft 231 and a nail poking plate 232. The rotating shaft 231 is rotatably connected to the inner wall of the nail bin 210 at two ends. The nail poking plate 232 is fixed on the rotating shaft 231 at one end and rotates together with the rotating shaft 231 to poke the nails 600 in the nail bin 210. The nail poking plate 232 is used to disturb the nails 600 in the nail bin, thereby preventing the nails 600 from being squeezed at the bin opening 220, ensuring that the nails 600 can smoothly pass through the bin opening 220 and enter the first nail channel 120, and avoiding the nails 600 from being stuck. The nail poking plate 232 comprises a first blade and a second blade. The first blade is fixed on the rotating shaft 231 at one end, 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. The second blade can be easily replaced after being worn out.

[0061] The nail arranging mechanism 300 and the nail channel 320:

[0062] As shown in Figures 3-5 , the nail arranging mechanism 300 comprises an entering nail plate 330. The entering nail plate 330 is provided with a second nail channel 310. The second nail channel 310 is combined with the first nail channel 120 to form the nail channel 320. The nail channel 320 can prevent the nails 600 from separating from the first nail channel 120. The design of the nail channel 320 can also effectively reduce the shaking and deviation of the nails 600 during the conveying process, thereby ensuring that each nail 600 moves stably along the predetermined path. By accurately controlling the movement trajectory of the nails 600, the working efficiency and reliability of the nail extractor can be further improved.

[0063] The second nail groove 310 has a width greater than the width of the first nail groove 120 and the nail head of the nail 600. The second nail groove 310 has a width greater than the width of the first nail groove 120, which can form a T-shaped nail channel 320. When the nail 600 enters the nail channel 320, it is completely positioned and cannot be stacked, thereby reducing the risk of jamming. Meanwhile, the second nail groove 310 has a width greater than the width of the nail head of the nail 600, which allows the nail head to be smoothly inserted into the second nail groove 310 and positioned, and only move along the extension direction of the nail channel 320.

[0064] The second nail groove 310 has a depth of 1.1mm to 1.6mm. When the depth of the second nail groove 310 is less than 1.1mm, the nail head and the nail part of the nail are prone to generate large friction with the bottom wall of the second nail groove 310, thereby jamming the nail. When the depth of the second nail groove is greater than 1.6mm, the nail heads of the front and rear nails 600 are prone to be stacked vertically, which is not conducive to the movement of the nail 600 in the nail channel 320, thereby jamming the nail.

[0065] The nail inlet of the nail channel 320 is located in the nail magazine 210 or communicates with the nail magazine 210. The nail inlet of the nail channel 320 is arranged inside the nail magazine 210, which ensures that the nails 600 on the first nail channel 320 within the range of the nail magazine 210 can directly enter through the nail inlet. As for those nails 600 that fail to fall into the first nail groove 120 and are stranded in the nail channel 320, they can be sent back to the nail magazine 210 under the action of the nail pushing plate 232, thereby realizing the recycling of the nails 600.

[0066] The nail inlet plate 330 is provided with a nail lifting surface 331 on one side of the nail magazine 210. 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, eliminating 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), so that the nail pushing plate 232 can push away the nails 600 stacked at the connection between the nail separating plate 110 and the nail inlet plate 330 when pushing the nails, thereby avoiding the jamming of the nails 600 caused by stacking and extrusion.

[0067] 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. When the nails 600 are jammed in the nail channel 320, the jammed position can be directly found from the second viewing groove 340, and the jammed nails 600 can be easily pushed through the second viewing groove 340 to eliminate the jamming.

[0068] The entering nail plate 330 comprises a first plate body 332 and a second plate body 333. The first plate body 332 and the second plate body 333 are connected to the separating nail plate 110 at one end and are detachably connected along the extending direction of the nail channel 320. The second plate body 333 is detachably connected to the separating nail plate 110. When the nail 600 is stuck in the second plate body 333, the stuck nail can be eliminated by detaching the second plate body 333, without the need to completely detach the entire entering nail plate 330, thereby saving maintenance time.

[0069] The entering nail plate 330 is located at the end of the outlet of the nail channel 320 and the end of the separating nail plate 110, and the distance L is 0.5-1.5 mm. When the distance L is greater than 1.5 mm, the nail 600 is easy 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 nail 600 is easy to be stuck in the outlet of the nail channel 320 when moving laterally to the falling nail channel 410, so that the nail 600 cannot smoothly enter the falling nail channel 410.

[0070] As shown in Figure 6 , a third cutout 112 is arranged at the outlet of the nail channel 320, the third cutout 112 extends in the opposite direction of the second direction 520 from the outlet of the nail channel 320, and the depth decreases. The third cutout 112 can guide the lateral movement of the nail 600 and avoid the problem of stuck nails at the outlet of the nail channel 320.

[0071] The falling nail mechanism 400 comprises a base 420, a side seat 430, a pushing nail plate 440, and a jet device 450.

[0072] As shown in Figures 7-8 , the falling nail mechanism 400 comprises a base 420, a side seat 430, a pushing nail plate 440, and a jet device 450.

[0073] The base 420 is fixed on the separating nail plate 110 and is located below the outlet of the nail channel 320. The side seat 430 is connected to the base 420, and a slide 470 and a falling nail channel 410 are formed between the base 420 and the side seat 430. The pushing nail plate 440 is slidingly connected in the slide 470, and a pushing nail groove 441 is arranged on the pushing nail plate 440. The pushing nail groove 441 is located below the outlet of the nail channel 320, receives the nail 600 dropped from the outlet of the nail channel 320, and moves the nail 600 to the falling nail channel 410. The jet device 450 comprises an air compressor, and the air outlet of the air compressor is communicated to the falling nail channel 410 and injects compressed gas into the falling nail channel 410 to push the nail 600 to move.

[0074] The nails 600 dropped in the nail passing channel 320 in turn are moved horizontally by the nail pushing plate 440 into the nail dropping channel 410 formed between the base 420 and the side seat 430. The nails 600 pass through the nail dropping channel 410 into the pipe connected to the nail dropping channel 410, and the jet device 450 pushes the nails 600 in the nail dropping channel 410 or the pipe to the automatic nailing device connected to the other end of the pipe by injecting compressed air into the nail dropping channel 410. The nail dropping mechanism 400 is used to ensure that the nails 600 can be accurately and efficiently delivered to the target position, avoiding the jamming or blocking problems 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 dropping channel 410 not only improves the stability of the overall structure, but also optimizes the flow path of the nails 600.

[0075] The base 420:

[0076] As shown in Figure 9 , the base 420 includes a positioning groove 421 located 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 achieve quick clamping while ensuring the accuracy of clamping.

[0077] The base 420 includes an extension groove 422 opened on the top thereof, which is located directly below the first nail passing groove 120 and extends the depth of the first nail passing groove 120. The extension groove 422 can extend the depth of the first nail passing groove 120 at the base 420, so that the nails 600 with longer nail columns can also smoothly pass through the base 420 without causing nail jamming at the base 420.

[0078] The base 420 includes a sliding groove 423 in which the nail pushing 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 nail pushing plate 440, so that the nail pushing plate 440 can smoothly slide in the sliding channel 470.

[0079] The base 420 is provided with a rounded corner guide 424 adapted to the nail pushing plate 440, which protrudes from the connection between the nail pushing groove 441 and the base 420. The rounded corner guide 424 can protrude into the nail pushing groove 441, and when the nails 600 move downward in the nail pushing groove 441, the rounded corner guide 424 can push the nails 600 to the center of the nail dropping channel 410, thereby avoiding the connection seam between the nail pushing groove 441 and the base 420 and preventing the nails 600 from being stuck on the connection seam.

[0080] The nail dropping channel 410:

[0081] As shown in 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 is opened on the base 420 and extends along the third direction 530. A second half slot 412 is opened on the side base 430 and extends along the third direction 530; the second half slot 412 is arranged opposite to the first half slot 411, and the two form the nail falling channel 410.

[0082] The nail falling channel is divided into the first half slot 411 and the second half slot 412, and the first half slot 411 and the second half slot 412 are combined. The first half slot 411 and the second half slot 412 can be machined separately, making it more convenient to machine the nail falling channel 4110. In addition, by machining the first half slot 411 and the second half slot 412 separately, the internal shape of the first half slot 411 and the second half slot 412 is easy to adjust, which is convenient for eliminating the nail step during the falling process of the nail 600 or correcting the posture of the nail 600 during the falling process by using the nail falling channel 410, greatly reducing the risk of nail 600 jamming.

[0083] 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 that are smoothly and sequentially connected 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, which is convenient for guiding the falling of the nail 600. The cross-sectional opening size of the second guide surface 4112 increases along the third direction 530, so that after the nail 600 falling from the first guide surface 4111 enters the second guide surface 4112, it will not be in contact with the inner wall of the second guide surface 4112, avoiding the risk of nail jamming due to the scraping of the second guide surface 4112. 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 will be righted by the third guide surface 4113 in the third guide surface 4113, so that the nail 600 can fall in a state of the nail cap on top and the nail column on the bottom. The nail 600 falling from the third guide surface 4113 enters the fourth guide surface 4114, and the opening size of the fourth guide surface 4114 does not change, so that after the nail 600 enters the fourth guide surface 4114, it can be further corrected to maintain a vertical downward state and fall out of the nail falling channel 410.

[0084] The first cutout 425 is located at the top of the base 420 and is above the first half groove 411, and the depth of the first cutout 425 decreases along the third direction 530. The first cutout 425 is located at the junction of the base 420 and the nail splitting plate 110, so that the nail 600 can avoid the gap between the base 420 and the nail splitting plate 110 in the pushing groove 441 during the falling process, and the nail 600 is prevented from being stuck at this position.

[0085] The falling nail channel 410 includes a second half groove 412 formed on the side base 430, and the second half groove 412 is arranged opposite to the first half groove 411, and the two half grooves form the falling nail channel 410. The second half groove 412 has a fifth guide surface 4121, a sixth guide surface 4122 and a seventh guide surface 4123 which are smoothly and sequentially connected in the third direction 530. The cross-sectional opening size of the fifth guide surface 4121 is the same, and the fifth guide surface 4121 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 pushing 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 lateral movement of the nail 600 in the pushing groove 441 and the entry of the nail 600 into the fifth guide surface 4121, and prevent the nail 600 from being stuck. The fifth guide surface 4121 falls out of the nail 600 and enters 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 scratching and sticking of the nail 600. The cross-sectional opening size of the seventh guide surface 4123 is the same, which can correct the inclined nail shank of the nail 600 during the falling process, avoid the nail 600 from falling out of the falling nail channel 410 in an excessively inclined state, and prevent the nail 600 from being stuck in the pipeline.

[0086] The pushing plate 440 and the pushing groove 441:

[0087] As shown in Figures 11-12 The pushing plate 440 includes a pushing plate 442 and a sliding block 443, and the pushing plate 442 and the sliding block 443 are fixedly connected and present an "L" shape.

[0088] The push plate 442 is slidingly connected in the slide 470. A nail pushing groove 441 is formed on the push plate 442 in the third direction 530 (the thickness direction of the separating plate 110 or the extending direction of the nail falling channel 410). The nail pushing groove 441 reciprocates between the outlet of the nail walking channel 320 and the nail falling channel 410, and moves the nails 600 falling from the outlet of the nail walking channel 320 into the nail falling channel 410. The nail pushing groove 441 can reciprocate between the nail walking channel 320 and the nail falling channel 410, and laterally push the nails 600 falling from the nail walking channel 320 into the nail falling channel 410. The nail pushing groove 441 pushes only one nail 600 at a time, so that only one nail 600 enters the nail falling channel 410 at a time.

[0089] The nail pushing groove 441 comprises a first groove section 4411, a second groove section 4412 and a third groove section 4413 connected in sequence. The first groove section 4411 is located at the port of the nail pushing groove 441. The opening size of the second groove section 4412 increases along the third direction 530. The opening size of the third groove section 4413 increases along the first direction 510. The first groove section 4411 is used to push the nails 600. The increasing opening size of the second groove section 4412 along the third direction 530 can reduce the contact opportunity between the nails 600 and the side wall of the second groove section 4412. The increasing opening size of the third groove section 4413 along the first direction 510 can increase the opening size and depth, further reduce the contact between the nails 600 and the side wall of the second groove section 4412, and reduce the risk of nail jamming.

[0090] The push plate 442 comprises a side cutout 4421. The side cutout 4421 is arranged on the push plate 442 and faces the separating plate 110. The cutout extends from the edge of the nail pushing groove 441 to the second direction 520 (the width direction of the separating plate 110). The side cutout 4421 can avoid the nail shank front end of the nail 600 from being stuck in the gap between the push plate 442 and the base 420 or the separating plate 110 during the pushing process of the nail pushing groove 441, and reduce the risk of nail jamming. The cutout size or depth of the side cutout 4421 gradually decreases along the second direction 520. The gradually decreasing cutout size or depth of the side cutout 4421 can avoid the nail shank from falling completely into the cutout, and reduce the risk of nail jamming.

[0091] A second cutout 4422 is formed on the push plate 442. The second cutout 4422 is located at the port of the nail pushing groove 441. The depth of the second cutout 4422 decreases along the third direction 530, and the width of the second cutout 4422 decreases from both sides to the middle direction. The decreasing depth of the second cutout 4422 along the third direction 530 can avoid the nail head of the nail 600 from hanging on the top surface of the push plate 442. The decreasing width of the second cutout 4422 from both sides to the middle direction can avoid the nail head of the nail 600 from hanging on the top surface of the side wall of the push plate 442, and reduce the risk of nail jamming.

[0092] 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.

[0093] 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. The inclined surface can avoid the sixth guide surface 4122 in the nail falling channel 410, so as to avoid the problem of stuck nails caused by the small included angle between the inclined surface and the sixth guide surface 4122.

[0094] The push nail plate 440 includes a sliding block 443 fixedly connected to the bottom of the push plate 442, and the sliding block 443 is slidingly connected in the slide 470 and slides with the push plate 442. The sliding block 443 is connected to the push plate 442, and the sliding block 443 can increase the contact area between the push nail plate 440 and the slide 470, thereby ensuring the stability of the sliding process. 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.

[0095] 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.

[0096] The height difference between the top surface of the push nail plate 440 and the upper surface of the nail separating plate 110 is 0.5-1 mm. When the height difference is less than 0.5 mm, the nail heads of the outermost nail 600 and 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 heads of the outermost nail 600 and the second-to-last nail 600 collide with each other, 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 forced to stack and be stuck. When the height difference is greater than 1 mm, the edges of the nail heads are likely to hang at the outlet of the nail channel 320, causing the nails to be stuck. When the height difference is 0.5-1 mm, the outermost nail 600 falls into the nail slot, the height of the nail head of the outermost nail 600 is lowered, and the nail head of the second-to-last nail 600 is pressed on the nail head of the outermost nail 600. When the outermost nail 600 is pushed horizontally, the nail head 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, thereby avoiding the problem of the nails being stuck in the nail channel 320.

[0097] The air injection device 450 includes a gas supply channel 451 formed in the base 420 or the side base 430, and the gas outlet of the gas supply channel 451 is arranged on the side wall of the nail falling channel 410.

[0098] As shown in Figure 10 The air injection device 450 can inject compressed gas into the nail falling channel 410 through the gas supply channel 451 to provide a pushing force for the falling nails 600 in the nail falling channel 410, so that the nails 600 can smoothly reach the automatic nailing device. Compared with arranging the gas supply channel 451 on the top of the nail falling channel 410, arranging the gas outlet of the gas supply channel 451 on the side wall of the nail falling channel 410 can avoid the disorder of the compressed gas flow, prevent the nails 600 from moving in the opposite direction in the nail falling channel 410, and affect the nail falling.

[0099] The air injection device 450 includes a gas distribution plate 453 fixed on the base 420, which includes a main gas channel 4511 and a gas distribution channel 4512 communicating with the main gas channel 4511. The main gas channel 4511 is in communication with the air compressor, and the gas distribution channel 4512 is in communication with different gas supply channels 451. The gas distribution plate 453 can uniformly guide the compressed air from the air compressor into each gas falling channel, and can ensure the consistency of the injection time of the compressed air in each gas falling channel.

[0100] The cover plate 460 includes a plurality of gas supply channels 451 arranged on the cover plate 460, and the gas supply channels 451 are in communication with the gas distribution plate 453.

[0101] As shown in Figure 14As shown, the nail dropping mechanism 400 comprises a cover plate 460 which is pressed on the side seat 430, and the cover plate 460 is provided with a nail blocking groove 461 which is arranged between the outlet of the nail walking channel 320 and the nail inlet of the nail dropping channel 410. The nail blocking groove 461 arranged on the cover plate 460 is arranged between the outlet of the nail walking channel 320 and the nail inlet of the nail dropping channel 410, so that when the nail pushing plate 440 pushes the nail 600, the nail 600 moves in the nail blocking groove 461, avoiding the nail 600 from being separated from the nail pushing plate 440.

[0102] The nail blocking groove 461 comprises a circular groove 4611 and a vertical groove 4612 which is communicated with the circular groove 4611, the circular groove 4611 is arranged above the nail dropping channel 410, and the vertical groove 4612 is arranged on the channel between the outlet of the nail walking channel 320 and the nail inlet of the nail dropping channel 410. When the nail 600 moves horizontally, it can move along the vertical groove 4612 and enter the nail dropping channel 410 from the circular groove 4611 when it reaches the circular groove 4611. The circular groove 4611 is connected with a guide hook 462 on the side close to the nail separating plate 110. The guide hook 462 can guide the nail 600 during the process of entering the circular groove 4611, so that the nail 600 moves towards the center of the circular groove 4611 and enters the nail dropping channel 410 from the center of the circular groove 4611, avoiding the nail 600 from being stuck at the edge of the circular groove 4611.

[0103] The first direction 510 is the extending direction of the nail walking channel 320 (the length direction of the nail separating plate 110), the second direction 520 is the direction perpendicular to the nail walking channel 320 (the width direction of the nail separating plate 110), and the third direction 530 is the extending direction of the nail dropping channel 410 (the thickness direction of the nail separating plate 110).

[0104] The above has described the utility model and its embodiments in a schematic way, which is not restrictive, and the drawings only show one of the embodiments of the utility model, and the actual structure is not limited thereto. Therefore, if the ordinary skilled in the art is inspired thereby, without departing from the creative purpose of the utility model, similar structural modes and embodiments are designed without creativity, which should all belong to the protection scope of the utility model.
