Description

Technical Field

[0001] The invention belongs to the technical field of coil nail guns, and in particular relates to a coil nail gun. Background Art

[0002] In the prior art, the coiled nails placed in the coiled nail gun are all wound by metal wire or metal card, and there are intervals between the nails, so a coiled nail gun that can use the coiled nails is specially equipped. CN203650447U discloses a nail feeding mechanism of a pneumatic coiled nail gun, including a gun head, a ballistic trajectory arranged in the gun head, a movable cover plate hinged on the gun head, a coiled nail box, and a nail placement frame arranged between the coiled nail boxes, characterized in that: a five-toothed nail feeding claw is provided at the junction of the ballistic trajectory and the nail placement frame; a nail stopping block matching the five-toothed nail feeding claw is provided on the movable cover plate; a position correction block matching the ballistic trajectory is provided on the movable cover plate; a compression spring is provided between the position correction block and the movable cover plate;

[0003] The coil nail gun can only be used with coil nails with spacing, and is not compatible with coil nails bonded in rows by flexible belts (the nails in the rows of coil nails are tightly fitted together); when the coil nail gun is used to drive nails, since the nails are connected in rows by cards or wires, the cards or wires remaining on the nails will wear out or remain in the driving path every time the nails are detached, causing the nails to get stuck later; every time the coil nail gun is used to operate on an object, it is also easy for iron wire to remain on the surface of the workpiece, causing the object to be scratched and broken. For example, if there is iron wire remaining on the surface of a pallet containing chemical products, the container will leak liquid, thereby affecting the product's qualification rate. Summary of the invention

[0004] The present invention is mainly aimed at the above-mentioned problems existing in the coil nail gun, and invents a coil nail gun. The present invention can smoothly push nails bonded in a row by a flexible belt into a nail guide structure, thereby avoiding the nail jamming phenomenon when driving nails and also improving the qualified rate of the product.

[0005] The above technical problem of the present invention is implemented through the following technical solutions: a coil nail gun, comprising a nail guide structure fixedly connected to a nail gun body and used for guiding the nails to be driven, and a nail storage structure capable of storing coil nails; characterized in that it comprises a nail feeding mechanism fixedly connected between the nail guide structure and the nail storage structure, the nail feeding mechanism comprising a nail feeding plate for guiding and limiting the moving direction of the coil nails, a pushing structure for pushing the coil nails toward the nail guide structure is provided on one side of the nail feeding plate, and both sides of the pushing structure in the same direction are respectively provided with a non-return assembly for preventing the coil nails from moving back to the nail storage structure; a clamping structure capable of pressing one end of the nail storage structure is provided above the nail feeding mechanism, and the clamping structure is also provided with a lever capable of moving the pushing structure and the non-return assembly away from the nails.

[0006] Preferably, the pushing structure comprises a pushing member and a moving member 1 arranged to surround the pushing member, and at least two pushing members are provided; a first groove is provided below the moving member 1, and the first groove is slidably matched with a first boss with a slope in the linkage member, wherein the linkage member semi-surrounds the pushing member and the moving member; perpendicular to the bottom of the nail transport plate, one end of the linkage member is connected through a brake, and the brake drives the pushing structure to reciprocate.

[0007] In the above arrangement, when the coil nail is pushed, the pushing member at this moment is higher than the plane of the nail transport plate and presses the coil nail against the cover plate, and the coil nail is pushed toward the nail guide structure under the action of the brake, wherein the brake is a one-way cylinder, and when the pushing structure moves toward the nail storage structure, the pushing member at this moment slides toward the lowest point of the slope of the first boss along with the moving member to release the pressure on the coil nail, thereby achieving smooth pushing in a reciprocating cycle.

[0008] Preferably, the non-return assembly includes a non-return member and a second movable member arranged to enclose the non-return member, and a second groove is provided below the second movable member; correspondingly, below the movable member, a second boss slidably engaged with the second groove is also provided on the nail transport plate, and the second boss has an inclined slope with respect to the horizontal plane.

[0009] In the above arrangement, when the pushing structure is not working and the pressure on the nails is released, since the coiled nails in the nail storage structure are gradually reduced, a spring sheet is provided on the circumference of the coiled nails to prevent them from loosening, thereby forming a force for pulling the coiled nails back. In the absence of a non-return component, the nails are prone to rewinding toward the nail storage structure. In the present invention, a section of the coiled nail will be left after the coiled nails are used up to the end, and the remaining coiled nails are the length from the separation from the pressure of the pushing structure to the guide nail structure. At this time, the non-return component arranged close to the guide nail structure plays a role in compressing the remaining coiled nails, which helps the newly installed coiled nails to seamlessly connect with the coiled nails left in the early stage. Even if there is a last nail left in the early stage, the nail can be effectively and smoothly pushed into the guide nail structure.

[0010] Preferably, perpendicular to the moving direction of the coil nail, waist-shaped holes are respectively provided on both sides of the moving member 1 and the moving member 2, and a protrusion 1 is provided on the side of the moving member 1 and the moving member 2 facing the shifting rod.

[0011] In the above arrangement, the provided raised portion 1 avoids the interference of the lever and is also conducive to the lever being able to quickly push the moving parts 1 and 2 toward the guide nail structure, wherein the first groove and the second groove provided below the moving parts 1 and 2 respectively can be set to a T-shape or a V-shape, so as to improve the stability of the sliding cooperation with the first boss and the second boss. During the movement of the moving parts 1 and 2, the moving push parts and the check parts move down along the waist-shaped holes by their own weight without the support of the first boss and the second boss, thereby releasing the pressure on the coiled nails.

[0012] Preferably, an openable or closable cover is provided above the nail transport plate, one end of the cover is hinged to the nail guide structure, and the other end of the cover extends toward the nail storage structure; along the moving direction of the rolled nail, two planes where the nail transport plate and the cover are in contact are also provided with slots for avoiding nail caps, and the slots are provided in multiple and equally spaced arrangements.

[0013] In the above arrangement, when the clamp is manually pushed toward the second protruding portion, the cover plate is separated from the connection with the nail feeding plate and the clamping structure also releases the pressure on the nail storage structure. Therefore, the arrangement of the cover plate combined with the clamping structure is convenient for coiling nails and also helps in daily maintenance and care of the present invention. The notches provided on the cover plate are used to avoid the nail caps of the nails on the one hand, and on the other hand, the multiple notches are compatible with nails of different lengths. The nails used can be T-shaped or F-shaped, thereby improving the versatility of the present invention.

[0014] Preferably, near the direction of the nail storage structure, one end of the cover plate is provided with a second protrusion, and a positioning portion is also provided relative to the second protrusion; the fixing structure includes a clamping member, and the clamping member slides in the positioning portion; perpendicular to the top of the cover plate, the second protrusion is threadedly engaged with a screw, and the elastic member is sleeved on the screw and arranged between the second protrusion and the clamping member; the clamping member is also provided with an extension portion extending toward the lever, and a floating member is also provided below the clamping member and is slidably engaged with the nail delivery plate.

[0015] The lever in the above arrangement is provided with a raised portion three for pushing the moving member one and the moving member two, and waist-shaped holes are respectively provided at both ends of the lever and slidably cooperate with the pins embedded in the nail feeding plate. Therefore, whenever the present invention needs to load the coil nail, the clamping member is manually pushed to move toward the raised portion two, and the lever, the moving member one and the moving member two are all moved toward the nail guide structure, so that the pushing member and the non-return member are moved away from the coil nail to leave a position for loading the coil nail; when the floating member is separated from the pressing of the clamping member, the floating member is extended toward the cover plate by the spring reset, and the lever is also separated from the push of the extension part. After that, the lever moves toward the nail storage structure under the action of the tension spring, and the end thereof abuts against one side of the floating member to limit the lever from continuing to move, thereby leaving a position for the clamping member to be locked back, thereby realizing the automatic locking function.

[0016] Preferably, a guide strip parallel to the nail transport plate is provided between the nail guide structure and the nail storage structure.

[0017] The guide strip in the above arrangement is provided with a slot, a plane in the slot is in the same plane as the nail transport plate, the guide strip assists the nail transport plate and restricts the freedom of the rolled nail in multiple directions, ensuring that the pushed nail is perpendicular to the moving direction of the rolled nail, thereby ensuring that the nail jamming phenomenon can be avoided when driving the nail.

[0018] Preferably, the nail transport plate is further provided with a nail limiting groove that enables the U-shaped nail sleeve to move on the nail transport plate.

[0019] The U-shaped nail in the above-mentioned setting is a kind of coiled nail, which is also bonded into a row by a flexible belt and can be coiled. On the one hand, the nail storage structure in which the coiled U-shaped nail is placed is consistent with the nail storage structure in which the T- and F-shaped nails are placed, thereby reducing the frequency of replacing the nail storage structure; on the other hand, the nail feeding mechanism can effectively push the T, F, and U-shaped nails into the nail guide structure to complete the nailing operation, thereby improving the versatility of the present invention.

[0020] Preferably, the fixing structure further comprises a wrench, wherein the wrench is fixedly connected to one end of the rotating shaft, and the other end of the rotating shaft extending toward the brake through the nail transport plate is fixedly connected to a steering member.

[0021] In the above arrangement, when a person manually pulls the pull member to rotate toward the nail storage structure, the steering member fixedly connected to the other end of the rotating shaft also rotates toward the nail guide structure. The steering member pushes the lever to move during the rotation, and the lever also pushes the moving member 1 and the moving member 2 to move, prompting the pushing member and the check member to release the pressure on the rolled nail. The above linkage structure cleverly solves the problem of being able to quickly load nails manually.

[0022] Preferably, a signal rod extending toward the coil nail is provided between the pushing structure and the brake.

[0023] In the above arrangement, the signal rod is installed on one side of the brake and an elastic member is installed therebetween. One end of the signal rod extending vertically is close to the guide nail structure, and one end extending toward the cover plate is also provided in the middle of the signal rod. When there is no coiled nail against the end of the signal rod extending out, under the action of the elastic member, one end of the signal rod is close to the guide nail structure to limit the movement of the safety switch, causing the present invention to be unable to be used normally, and it is also a signal to remind the user that there is no nail.

[0024] In summary, the present invention has the following advantages compared with the prior art:

[0025] When the coil nails are installed in the present invention, the manual operation pushes the clamping structure to move, and the lever linked to the clamping structure also pushes the pushing structure and the non-return assembly to move toward the nail guide mechanism, prompting the pushing structure and the non-return assembly to move away from the coil nails to make way for the nail installation position, so that the manual operation can smoothly install the coil nails bonded in a row by the flexible belt on the nail transport plate, and then the pushing structure and the non-return assembly press the coil nails; after the nail installation is completed, under the action of the brake, the pushing structure pushes the pressed coil nails back and forth; wherein the pushing structure moves toward the nail guide structure to press the coil nails, and the pushing structure moves toward the nail storage structure to release the pressing of the coil nails, so the cycle is repeated to realize the automatic and smooth pushing of the coil nails into the nail driving path, and the nail jamming phenomenon is not easy to occur during the pushing process; the coil nails used in the present invention are bonded by the flexible belt, and the combination of the two can effectively avoid the occurrence of nail jamming during nail driving, for example, even if there is still a flexible belt remaining on the nail, it will not cause damage to the nail driving path, and it can also effectively avoid scratches and cuts on objects.

[0040] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0041] Embodiment 1:

[0042] like Figures 1 to 8 As shown, the coil nail gun includes a nail feeding mechanism 3 fixedly connected between the nail guide structure 2 and the nail storage structure 4, the nail feeding mechanism 3 includes a nail feeding plate 31 for guiding and limiting the moving direction of the coil nail, a pushing structure 32 for pushing the coil nail toward the nail guide structure 2 is provided on one side of the nail feeding plate 31, and a non-return assembly 33 for preventing the coil nail from moving back to the nail storage structure 4 is provided on both sides of the pushing structure 32 in the same direction; a clamping structure 35 for pressing one end of the nail storage structure 4 is provided above the nail feeding mechanism 3, and the clamping structure 35 is also provided with a lever 351 capable of moving the pushing structure 32 and the non-return assembly 33 away from the coil nail.

[0043] The pushing structure 32 includes a pushing member 321 and a moving member 322 arranged to surround the pushing member 321, and at least two pushing members 321 are provided; a first groove 3221 is provided below the moving member 322, and the first groove 3221 is slidably matched with a first boss 3231 with a slope in the linkage member 323, wherein the linkage member 323 semi-surrounds the pushing member 321 and the moving member 322; perpendicular to the bottom of the nail transport plate 31, one end of the linkage member 323 is connected through the brake 36, and the brake 36 drives the pushing structure 32 to reciprocate. In this embodiment, when the coil nail is pushed, the pushing member 321 at this moment is higher than the plane of the nail transport plate 31 and presses the coil nail against the cover plate 34. Under the action of the brake 36, the coil nail is pushed to move toward the nail guide structure 2. When the pushing structure 32 moves toward the nail storage structure 4, the pushing member 321 at this moment slides toward the lowest point of the slope of the first boss 3231 along with the moving member 1 322 to release the pressure on the coil nail, thereby realizing smooth pushing in a reciprocating cycle.

[0044] The non-return assembly 33 includes a non-return member 331 and a second moving member 332 arranged to enclose the non-return member 331, and a second groove 3321 is provided below the second moving member 332; correspondingly, below the second moving member 332, a second boss 311 slidably matched with the second groove 3321 is also provided on the nail transport plate 31, wherein the second boss 311 has an inclined slope with respect to the horizontal plane. In the present embodiment, when the pushing structure 32 is not in operation and the pressure on the nails is released, a spring sheet is provided in the circumferential direction of the coiled nails to prevent the coiled nails in the nail storage structure 4 from becoming loose as the number of coiled nails gradually decreases, thereby forming a force for pulling the coiled nails back. In the absence of the non-return component 33, the nails are prone to rewinding toward the nail storage structure 4. In the present invention, a section of the coiled nails will be left after the coiled nails are used to the end. The remaining coiled nails are the length from the separation from the pressure of the pushing structure 32 to the guide nail structure 2. At this time, the non-return component 33 arranged close to the guide nail structure 2 plays a role in pressing the remaining coiled nails, which helps the newly installed coiled nails to seamlessly connect with the coiled nails left in the early stage. Even if there is a last nail left in the early stage, the nail can be effectively and smoothly pushed into the guide nail structure 2. The present invention achieves smooth pushing of the coiled nails while also avoiding the phenomenon of nail jamming.

[0045] Perpendicular to the moving direction of the coil nail, waist-shaped holes 3222 are respectively provided on both sides of the moving member 1 322 and the moving member 2 332 , and a protrusion 1 3322 is provided on one side of the moving member 1 322 and the moving member 2 332 facing the lever 351 . The raised portion 3322 provided in the present embodiment avoids the interference of the lever 351 and is also conducive to the lever 351 to quickly push the moving member 1 322 and the moving member 2 332 to move toward the guide nail structure 2, wherein the first groove 3221 and the second groove 3321 respectively provided under the moving member 1 322 and the moving member 2 332 can be set to a T-shape or a V-shape, so as to improve the stability of the sliding cooperation with the first boss 3231 and the second boss 311. During the movement of the moving member 1 322 and the moving member 2 332, the moving push member 321 and the check member 331 move down along the waist-shaped hole 3222 under their own weight without the support of the first boss 3231 and the second boss 311, thereby releasing the pressure on the coil nail.

[0046] A cover plate 34 that can be opened or closed is provided above the nail feeding plate 31, one end of the cover plate 34 is hinged to the nail guide structure 2, and the other end of the cover plate 34 extends toward the nail storage structure 4; along the direction of movement of the rolled nail, the two planes where the nail feeding plate 31 and the cover plate 34 are attached are also provided with notches 312 for avoiding the nail cap, and the notches 312 have multiple and equally spaced arrangements. In this embodiment, when the clamp 352 is manually pushed toward the second protrusion 341, the cover plate 34 is disconnected from the nail feeding plate 31 and the clamping structure 35 also releases the pressure on the nail storage structure 4. Therefore, the combination of the cover plate 34 and the clamping structure 35 is convenient for rolling nail feeding and also helps the daily maintenance and care of the present invention; the notches 312 provided on the cover plate 34 are used to avoid the nail cap of the nail, and on the other hand, the multiple notches 312 can be compatible with nails of different lengths, and the nails used can be T-shaped or F-shaped, thereby improving the versatility of the present invention.

[0047] Close to the nail storage structure 4, one end of the cover plate 34 is provided with a second protrusion 341, and a positioning portion 342 is further provided relative to the second protrusion 341; the fixing structure 35 includes a clamping member 352, and the clamping member 352 slides in the positioning portion 342; perpendicular to the top of the cover plate 34, the second protrusion 341 is threadedly matched with a screw, and the elastic member 353 is sleeved on the screw and arranged between the second protrusion 341 and the clamping member 352; the clamping member 352 is also provided with an extension portion 3521 extending toward the lever 351, and a floating member 37 is also provided below the clamping member 352 to slide with the nail transport plate 31. In this embodiment, the lever 351 is provided with a protrusion 3 for pushing the moving member 1 322 and the moving member 2 332. Both ends of the lever 351 are also provided with waist-shaped holes and slideably cooperate with the pins embedded in the nail transport plate 31. Therefore, whenever the present invention needs to load the coiled nail, the clamping member 352 is manually pushed to move toward the protrusion 2 341, and the lever 351, the moving member 1 322 and the moving member 2 332 are all moved toward the nail guide structure 2, so that the pushing member 321 and the check member 321 are pushed. Component 331 is away from the coil nail and leaves a position for loading the coil nail; when the floating component 37 is released from the pressure of the clamping component 352, the floating component 37 is extended toward the cover plate 34 through the spring reset. At this time, the lever 351 is also released from the push of the extension part 3521. Then, the lever 351 moves toward the nail storage structure 4 under the action of the tension spring, and the end of the lever 351 abuts against one side of the floating component 37 to limit the lever 351 from continuing to move, thereby leaving a position for the clamping component 352 to be locked back, thereby realizing the automatic locking function.

[0048] A guide bar 38 parallel to the nail transport plate 31 is further provided between the nail guide structure 2 and the nail storage structure 4. In this embodiment, a notch is provided in the guide bar 38, and a plane in the notch is in the same plane as the nail transport plate 31. The guide bar 38 assists the nail transport plate 31 and restricts the freedom of the rolled nail in multiple directions, ensuring that the pushed nails are perpendicular to the moving direction of the rolled nails, thereby ensuring that the nail jamming phenomenon can be avoided when driving the nails.

[0049] A signal rod 39 extending toward the coiled nail is provided between the push structure 32 and the brake 36. The signal rod 39 provided in this embodiment is installed on one side of the brake 36 and an elastic member is also installed therebetween. One end of the signal rod 39 extending vertically is close to the nail guide structure 2, and one end extending toward the cover plate 34 is also provided in the middle of the signal rod 39. When there is no coiled nail against the end of the signal rod 39 extending out, under the action of the elastic member, one end of the signal rod 39 is closely attached to the nail guide structure 2 to limit the movement of the safety switch, so that the present invention cannot be used normally, and it is also a signal to remind the user that there is no nail.

[0050] Directions:

[0051] Before using the present invention, the cover plate 34 is first opened to load the rolled nails into the nail storage structure 4. At this moment, the clamping structure 35 is manually pushed to move relative to the nail storage structure 4. At the same time, the lever 351 linked to the clamping structure 35 also pushes the pushing structure 32 and the non-return assembly 33 to move toward the direction of opening the cover plate 34, so that the pushing structure 32 and the non-return assembly 33 are both lower than the plane where the rolled nails are placed on the nail feeding plate 31. Therefore, the manual operation can quickly load the rolled nails into the guide strip 38 and the notch 312 provided on the nail feeding plate 31 to limit the rolling nails. The coiled nail is free, and after the nailing is completed, the cover is closed, and the pushing structure 32 and the non-return assembly 33 compress the coiled nail. Under the action of the brake, the pushing structure 32 moves back and forth, thus cyclically repeating to automatically and smoothly push the coiled nail into the nailing path; wherein the pushing structure 32 sends a nail each time with a distance greater than that of a nail, so after the nail is sent, the nail still has a strong support to keep the first nail in the nailing path against the cover plane, thus ensuring that the nail is parallel to the nailing path, and effectively avoiding the nail jamming during the nailing process.

[0052] Embodiment 2:

[0053] like Figures 9 to 12 As shown, the difference between this embodiment and embodiment 1 is that the nail transport plates used for guiding and limiting nails are inconsistent, and the way in which the locking structure presses the nail box cover is also inconsistent.

[0054] The nail feeding plate 31 is also provided with a nail limiting groove 313 that allows the U-shaped nail sleeve to move on the nail feeding plate 31. The U-shaped nail in this embodiment is a kind of coiled nail, which is also adhered in a row by a flexible belt and can be coiled. On the one hand, the nail storage structure 4 in which the coiled U-shaped nail is placed is consistent with the nail storage structure 4 in which the T and F-shaped nails are placed, thereby reducing the frequency of replacing the nail storage structure 4; on the other hand, the nail feeding mechanism 3 can effectively push the T, F, and U-shaped nails into the nail guide structure 2 to complete the nailing operation, thereby improving the versatility of the present invention.

[0055] The clamping structure 35 further includes a puller 354, which is fixedly connected to one end of the rotating shaft 355. The other end of the rotating shaft 355 extending through the nail feeding plate 31 toward the brake 36 is fixedly connected to a steering member 356. In this embodiment, when a person manually pulls the puller 354 to rotate toward the nail storage structure 4, the steering member 356 fixedly connected to the other end of the rotating shaft 355 at this moment also rotates toward the nail guide structure 2. The steering member 356 pushes the lever 351 to move during the rotation process, and the lever 351 also pushes the moving member 1 322 and the moving member 2 332 to move, so that the pushing member 321 and the check member 331 release the pressure on the rolled nail. The above linkage structure cleverly solves the problem of manual fast loading of nails.

[0056] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
